This communication contains "forward-looking statements" within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. In this context, forward-looking statements often address expected future business and financial performance and financial condition, and often contain words such as "expect," "anticipate," "intend," "plan," "believe," "seek," "see," "will," "would," "target," and similar expressions and variations or negatives of these words.

Forward-looking statements address matters that are, to varying degrees, uncertain and subject to risks, uncertainties and assumptions, many of which that are beyond DuPont's control, that could cause actual results to differ materially from those expressed in any forward-looking statements. Forward-looking statements are not guarantees of future results. Some of the important factors that could cause DuPont's actual results to differ materially from those projected in any such forward-looking statements include, but are not limited to: (i) the parties’ ability to meet expectations regarding the timing, completion and accounting and tax treatments of the proposed transaction with IFF; changes in relevant tax and other laws, (ii) failure to obtain necessary regulatory approvals, approval of IFF’s shareholders, anticipated tax treatment or any required financing or to satisfy any of the other conditions to the proposed transaction with IFF, (iii) the possibility that unforeseen liabilities, future capital expenditures, revenues, expenses, earnings, synergies, economic performance, indebtedness, financial condition, losses, future prospects, business and management strategies that could impact the value, timing or pursuit of the proposed transaction with IFF, (iv) risks and costs and pursuit and/or implementation of the separation of the N&B Business, including timing anticipated to complete the separation, any changes to the configuration of businesses included in the separation if implemented, (v) risks and costs related to the Dow Distribution and the Corteva Distribution (together, the “Distributions”) including (a) with respect to achieving all expected benefits from the Distributions; (b) the incurrence of significant costs in connection with the Distributions, including costs to service debt incurred by the Company to establish the relative credit profiles of Corteva, Dow and DuPont and increased costs related to supply, service and other arrangements that, prior to the Dow Distribution, were between entities under the common control of DuPont; (c) indemnification of certain legacy liabilities of E.

4

credit rating downgrade and (ix) other risks to DuPont's business, operations and results of operations including from: failure to develop and market new products and optimally manage product life cycles; ability, cost and impact on business operations, including the supply chain, of responding to changes in market acceptance, rules, regulations and policies and failure to respond to such changes; outcome of significant litigation, environmental matters and other commitments and contingencies; failure to appropriately manage process safety and product stewardship issues; global economic and capital market conditions, including the continued availability of capital and financing, as well as inflation, interest and currency exchange rates; changes in political conditions, including tariffs, trade disputes and retaliatory actions; impairment of goodwill or intangible assets; the availability of and fluctuations in the cost of energy and raw materials; business or supply disruption, including in connection with the Distributions; ability to effectively manage costs as the company’s portfolio evolves; security threats, such as acts of sabotage, terrorism or war, natural disasters, weather events and patterns, and global health risks and pandemics, which could result in a significant operational event for DuPont, adversely impact demand or production; ability to discover, develop and protect new technologies and to protect and enforce DuPont's intellectual property rights; unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism or outbreak of war or hostilities, as well as management's response to any of the aforementioned factors. These risks are and will be more fully discussed in DuPont's current, quarterly and annual reports and other filings made with the U.S. Securities and Exchange Commission, in each case, as may be amended from time to time in future filings with the SEC. While the list of factors presented here is considered representative, no such list should be considered a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material adverse effect on DuPont’s consolidated financial condition, results of operations, credit rating or liquidity. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made. DuPont assumes no obligation to publicly provide revisions or updates to any forward-looking statements whether as a result of new information, future developments or otherwise, should circumstances change, except as otherwise required by securities and other applicable laws. A detailed discussion of some of the significant risks and uncertainties which may cause results and events to differ materially from such forward-looking statements is included in the section titled “Risk Factors” (Part I, Item 1A of this Form 10-K).

DuPont de Nemours, Inc.

PART I

ITEM 1.  BUSINESS

DuPont is a Delaware corporation formed in 2015 (formerly, DowDuPont Inc.), for the purpose of effecting an all-stock merger of equals transactions between The Dow Chemical Company ("Historical Dow") and E. I. du Pont de Nemours and Company ("Historical EID"). Effective August 31, 2017, pursuant to the merger of equals transaction contemplated by the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017 ("DWDP Merger Agreement"), Historical Dow and Historical EID each merged with subsidiaries of DowDuPont Inc. ("DowDuPont") and, as a result, Historical Dow and Historical EID became subsidiaries of DowDuPont (the "Merger"). Prior to the Merger, DowDuPont did not conduct any business activities other than those required for its formation and matters contemplated by the DWDP Merger Agreement. For purposes of DowDuPont's financial statement presentation, Historical Dow was determined to be the accounting acquirer in the Merger and Historical EID's assets and liabilities are reflected at fair value as of the Merger Effectiveness Time. The financial statements of Historical Dow for periods prior to the Merger are considered to be the historical financial statements of the Company.

Effective as of 5:00 p.m. on April 1, 2019, DowDuPont completed the separation of its materials science business into a separate and independent public company by way of a distribution of Dow through a pro rata dividend in-kind of all of the then-issued and outstanding shares of Dow’s common stock, par value $0.01 per share (the “Dow Common Stock”), to holders of the Company’s common stock, par value $0.01 per share (the “DowDuPont common stock”), as of the close of business on March 21, 2019 (the “Dow Distribution”).

Effective as of 12:01 a.m. on June 1, 2019, DuPont de Nemours, Inc. (formerly known as DowDuPont Inc.), completed the separation of its agriculture business into a separate and independent public company by way of a distribution of Corteva through a pro rata dividend in-kind of all of the then-issued and outstanding shares of Corteva’s common stock, par value $0.01 per share (the “Corteva Common Stock”), to holders of the Company’s common stock, par value $0.01 per share, as of the close of business on May 24, 2019 (the “Corteva Distribution” and, together with the Dow Distribution, the “Distributions”).

Following the Corteva Distribution, the Company holds the specialty products business. On June 1, 2019, DowDuPont changed its registered name from "DowDuPont Inc." to "DuPont de Nemours, Inc." doing business as "DuPont" (the "Company"). Beginning on June 3, 2019, the Company's common stock is traded on the NYSE under the ticker symbol "DD".

Today, DuPont is a global innovation leader with technology-based materials, ingredients and solutions that help transform industries and everyday life by applying diverse science and expertise to help customers advance their best ideas and deliver essential innovations in key markets including electronics, transportation, building and construction, health and wellness, food and worker safety. The Company had approximately 35,000 employees as of December 31, 2019. The Company has subsidiaries in about 70 countries worldwide and manufacturing operations in about 40 countries. See Note 24 to the Consolidated Financial Statements for details on the location of the Company's sales and property.

On December 15, 2019, DuPont and Nutrition & Biosciences, Inc. (presently a wholly owned subsidiary of DuPont) (“N&B Inc.”), entered into definitive agreements, including the Merger Agreement, with IFF, and Neptune Merger Sub I Inc. (a wholly owned subsidiary of IFF) (“Merger Sub I”), pursuant to which and subject to the terms and conditions therein, (1) DuPont will transfer its Nutrition and Biosciences business (the "N&B Business") to N&B Inc. (the “Contribution”), (2) DuPont will distribute to its stockholders all of the issued and outstanding shares of common stock, par value $0.01 per share, of N&B Inc. (the “N&B Inc. Common Stock”) held by DuPont by way of either (at DuPont’s option) a pro rata dividend or an exchange offer (the “N&B Distribution”), and (3) Merger Sub I will merge with and into N&B Inc., with N&B Inc. as the surviving corporation (the “N&B Merger” and collectively with the Contribution and the N&B Distribution, the "Proposed N&B Transaction"). As a result of the N&B Merger, the existing shares of N&B Inc. will be automatically converted into the right to receive a number of shares of IFF common stock, par value $0.125 per share (“IFF Common Stock”). When the N&B Merger is completed, holders of DuPont’s common stock (“DuPont Common Stock”) will own approximately 55.4% of the outstanding shares of IFF on a fully diluted basis. The actual value of IFF Common Stock received by DuPont stockholders will depend on the value of such shares at the time the transaction closes, and DuPont stockholders may receive more or less than the value announced at the time of the signing of the definitive agreements. In addition, as part of the proposed transaction, DuPont will receive a one-time $7.3 billion cash payment, subject to adjustment, (the “Special Cash Payment”). The Special Cash Payment is subject to adjustment due to, among other things, variances in net working capital, and, therefore, could be less or more than anticipated.

6

At DuPont's election (subject to certain restrictions), the N&B Distribution may be effected by means of a pro rata dividend in a spin-off transaction or an exchange offer for outstanding DuPont shares in a split-off transaction (or a combination of both). If DuPont elects a spin-off transaction, all DuPont stockholders will participate on a pro rata basis. If DuPont elects a split-off, then it will conduct an exchange offer and all DuPont stockholders will elect whether to exchange DuPont shares for shares of N&B Inc. (subject to any terms and conditions announced by DuPont with respect thereto). However, to the extent the split-off does not result in the distribution of all of the outstanding shares of N&B Inc., the additional shares of N&B Inc. still held by DuPont would be distributed in a spin-off transaction on a pro rata basis to all DuPont stockholders.

The Proposed N&B Transaction is expected to close by the end of the first quarter of 2021, subject to approval by IFF stockholders and other customary closing conditions, including regulatory approvals and receipt by DuPont of an opinion of tax counsel.

Basis of Presentation

The Consolidated Financial Statements included in this annual report present the financial position of DuPont as of December 31, 2019 and 2018 and the results of operations of DuPont for the years ended December 31, 2019, 2018 and 2017 giving effect to the Distributions, with the historical financial results of Dow and Corteva reflected as discontinued operations.

SEGMENT INFORMATION

DuPont’s worldwide operations are managed through global businesses, which are reported in five reportable segments: Electronics & Imaging; Nutrition & Biosciences; Transportation & Industrial; Safety & Construction, and Non-Core.

Effective June 1, 2019, DuPont changed its management and reporting structure resulting in the creation of a new Non-Core segment ("Second Quarter Segment Realignment").

These changes resulted in the following being realigned to Non-Core:

• Photovoltaic and Advanced Materials business unit (including the HSC Group joint ventures: DC HSC Holdings LLC and Hemlock Semiconductor L.L.C) from the Electronics & Imaging segment;

• Biomaterials and Clean Technologies business units from the Nutrition & Biosciences segment;

• DuPont Teijin Films joint venture from the Transportation & Industrial (formerly Transportation & Advanced Polymers) segment; and

• Sustainable Solutions business unit from the Safety & Construction segment.

In addition, the following changes have occurred:

• Consolidation of the Nutrition & Health business with the Industrial Biosciences business within the Nutrition & Biosciences reportable segment. Previously, Nutrition & Health and Industrial Biosciences were separate operating segments which did not meet the quantitative thresholds.

• Pre-commercial activities related to the Biomaterials business unit was realigned from Corporate to Non-Core, with the remaining pre-commercial activities realigned to the Nutrition & Biosciences segment.

In addition to the Second Quarter Segment Realignment, effective October 1, 2019, Electronics & Imaging realigned its product lines as Image Solutions, Interconnect Solutions and Semiconductor Technologies.

See Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations and Note 24 to the Consolidated Financial Statements for additional information concerning the Company’s operating segments.

SIGNIFICANT CUSTOMERS AND COMPETITION

In 2019, no significant portion of the Company's sales was dependent upon a single customer. The markets in which the Company participates compete primarily through technology, range of products and services, performance, quality, reliability, brand, reputation, service and support. The Company provides extensive support, technical services and testing services for its customers, in addition to new product development. The Company believes that its proprietary product and process technologies, robust product and application development pipelines, customer intimacy, global manufacturing capability and local service capability enable it  to compete successfully.

Against this competitive backdrop, value-in-use is the primary driver of price for the Company’s products, although price is impacted by many factors including, among others, fluctuations in supply and demand, and availability and cost of key manufacturing inputs including raw materials and energy.

DISTRIBUTION

Most products are marketed primarily through the Company's sales organization, although in some regions, more emphasis is placed on sales through distributors. The Company has a diverse worldwide network which markets and distributes the Company's brands to customers globally. This network consists of the Company's sales and marketing organization partnering with distributors, independent retailers, cooperatives and agents throughout the world.

BACKLOG

In general, the Company does not manufacture its products against a backlog of orders and does not consider backlog to be a significant indicator of the level of future sales activity. Production and inventory levels are based on the level of incoming orders as well as projections of future demand. Therefore, the Company believes that backlog information is not meaningful to understanding its overall business and should not be considered a reliable indicator of the Company's ability to achieve any particular level of revenue or financial performance.

INTELLECTUAL PROPERTY

Trade Secrets: Trade secrets are an important part of the Company's intellectual property. Many of the processes used to make products are kept as trade secrets which, from time to time, may be licensed to third parties. DuPont vigilantly protects all of its intellectual property including its trade secrets. When the Company discovers that its trade secrets have been unlawfully taken, it reports the matter to governmental authorities for investigation and potential criminal action, as appropriate. In addition, the Company takes measures to mitigate any potential impact, which may include civil actions seeking redress, restitution and/or damages based on loss to the Company and/or unjust enrichment.

16

Patents: The Company continually applies for and obtains patents in many countries, including the U.S., and has access to a large patent portfolio, both owned and licensed. DuPont’s rights under these patents and licenses, as well as the products made and sold under them, are important to the Company in the aggregate. The protection afforded by these patents varies based on country, scope of individual patent coverage, as well as the availability of legal remedies in each country. The term of these patents is generally about twenty years, but varies depending on country. This significant patent estate may be leveraged to align with the Company’s strategic priorities within and across product lines. At December 31, 2019, the Company owned more than 27,000 patents and patent applications globally. Approximately 80% of the Company’s patent estate has a remaining term of more than 5 years.

Trademarks: The Company owns or licenses many trademarks that have significant recognition at the consumer retail level and/or has a product line to product line level. Ownership rights in trademarks do not expire if the trademarks are continued in use and properly protected.

DowDuPont Intellectual Property Agreements: In connection with the separation and distribution of Dow and Corteva, effective April 1, 2019 and June 1, 2019, respectively, the Company entered into intellectual property license agreements related to fields of use within the scope of the respective businesses, (together, the “IP License Agreements”). The IP License Agreements set forth the terms and conditions under which the applicable parties may use in their respective businesses, certain know-how (including trade secrets), copyrights, trademarks, and software, and certain patents and standards, allocated to another party pursuant to the DowDuPont Separation and Distribution Agreement.

ITEM 1A. RISK FACTORS

The Company's operations could be affected by various risks, many of which are beyond its control. Based on current information, the Company believes that the following identifies the most significant risk factors that could affect its operations. Past financial performance may not be a reliable indicator of future performance and historical trends should not be used to anticipate results or trends in future periods.

Risks Relating to the Proposed N&B Transaction and the Dow and Corteva Distributions

DuPont is pursuing a plan to separate and combine its Nutrition & Biosciences business with IFF in a Reverse Morris Trust transaction. This proposed transaction involves risks, including risks that the proposed transaction may not be completed on the currently contemplated timeline or at all and may not achieve the intended benefits.

On December 15, 2019, DuPont and IFF announced they had entered definitive agreements to combine DuPont’s Nutrition & Biosciences business (the "N&B Business") with IFF in a transaction that would result in IFF issuing shares to DuPont shareholders. The proposed transaction with IFF, (the "Proposed N&B Transaction") is expected to close by the end of the first quarter of 2021, subject to approval by IFF stockholders and other customary closing conditions, including regulatory approvals and receipt by DuPont of an opinion of tax counsel. A voting agreement was entered on December 15, 2019, with Winder Investment Pte. Ltd., a shareholder of IFF. Pursuant to the voting agreement, Winder agrees, among other things, to vote in favor of the issuance of IFF common stock in connection with the N&B Transaction and any proposal or action presented to effectuate the issuance. The voting agreement terminates on September 30, 2020. The satisfaction of the required conditions could delay the consummation of the proposed transaction with IFF or prevent it from occurring. Further, there can be no assurance that the conditions to the closing of the proposed transaction will be satisfied or waived or that the proposed transaction will be consummated. With respect to regulatory approvals, there can be no assurance that the required regulatory approvals will be received in a timely manner or at all, or that such approvals will not contain adverse conditions. Failure to consummate the proposed transaction in a timely manner or at all could negatively impact the market price of DuPont’s Common Stock, as well as DuPont’s future business and its financial condition, results of operations and cash flows.

The announcement and pendency of the Proposed N&B Transaction could cause disruptions in DuPont’s and IFF’s respective businesses, including potential adverse reactions or changes to business relationships and competitive responses to the transaction. The transaction will also require significant amounts of time and effort which could divert management’s attention from operating and growing our business. DuPont has incurred and expects to incur a number of non-recurring costs in connection with the Proposed N&B Transaction. These costs and expenses include financial, legal, accounting, consulting and other advisory fees and expenses; reorganization and restructuring costs; severance/employee benefit-related expenses; regulatory and SEC filing fees and expenses; printing expenses and other related charges some of which are payable by DuPont regardless of whether the proposed transaction is consummated. The Merger Agreement with IFF also generally requires DuPont to operate the N&B Business in the ordinary course pending consummation of the Mergers and restricts DuPont, without IFF’s consent, from taking certain specified actions until the proposed transaction is consummated or the Merger Agreement is terminated, including making certain acquisitions and divestitures and entering into certain contracts. Any of the foregoing could adversely affect DuPont’s business, financial condition and results of operations. Declines in sales, earnings and cash flows could also result in future asset impairments (including goodwill).

Even if the proposed transaction is completed, there can be no assurance that DuPont will be able to realize the anticipated value and benefits therefrom or that the new combined company will perform as expected. Further, if the proposed transaction is completed, the combined value of the DuPont Common Stock and the shares of IFF Common Stock issued as consideration in the N&B Merger could be greater than, less than or equal to what the value of DuPont’s Common Stock would have been had the proposed transaction not occurred.

In connection with the proposed transaction with IFF, N&B Inc. entered into a Bridge Commitment Letter to secure from certain financing sources, committed financing in an aggregate principal amount of $7.5 billion, (the “Bridge Loans”) provided that such commitment shall be reduced by, among other things, (1) the amount of net cash proceeds received by N&B Inc. from any issuance of senior unsecured notes pursuant to a Rule 144A offering or other private placement (the "N&B Notes Offering") and (2) certain qualifying term loan commitments under senior unsecured term loan facilities. The proceeds of funded Bridge Loans, if any, would be used by N&B Inc. to make the Special Cash Payment and to pay the related transaction fees and expenses.

In January 2020, N&B Inc. entered into a senior unsecured term loan agreement in the amount of $1.25 billion split evenly between three- and five-year facilities, the proceeds of which shall be used to make the Special Cash Payment and to pay the related transaction fees and expenses. Such term loan facility, reduced the commitments under the Bridge Commitment Letter. The remaining $6.25 billion is expected to be funded through the N&B Notes Offering, if any, and/or the Bridge Loans. The commitments under the Bridge Commitment Letter and the availability of funding under the term loan are subject to customary closing conditions.

18

Borrowing under the term loan facility and, if any, under the Bridge Loans would occur substantially concurrently with closing of the transaction. Any issuance of senior unsecured notes pursuant to a Rule 144A offering or other private placement for some or all the remaining $6.25 billion would likely occur in advance of the closing. If such issuance occurred prior to the closing, during the period between the offering and the closing of the Proposed N&B Transaction the debt of DuPont on a consolidated basis would be materially increased. Such increase, if any, is not expected to adversely impact DuPont’s results of operations, financial position or access to liquidity. If any notes are issued prior to closing and the proposed transaction with IFF is subsequently terminated, DuPont expects that N&B Inc. would immediately repay any such debt.

The separation and combination of DuPont’s Nutrition & Biosciences business with IFF could result in significant tax liability to DuPont.

Following the N&B Merger with N&B Inc. as the surviving company, except as agreed by the parties, N&B Inc. will merge with and into Neptune Merger Sub II LLC (a wholly owned subsidiary of IFF) (“Merger Sub II”), with Merger Sub II surviving as a wholly owned subsidiary of IFF (the “Second Merger,” and together with the N&B Merger, the “Mergers”).

The N&B Distribution and Mergers are expected to be tax-free to DuPont stockholders for U.S. federal income tax purposes (except to the extent that cash is paid to DuPont stockholders in lieu of fractional shares pursuant to the Merger Agreement), and the Contribution, N&B Distribution, and Special Cash Payment are expected to result in no recognition of gain or loss by DuPont for U.S. federal income tax purposes.

The proposed transaction with IFF is conditioned on DuPont's receipt of an opinion from Skadden, Arps, Slate, Meagher & Flom LLP regarding (i) the qualification of the Contribution, N&B Distribution and Special Cash Payment as a “reorganization” within the meaning of Sections 368(a), 361 and 355 of the Internal Revenue Code of 1986 (the “Code”), (ii) the nonrecognition of gain or loss by DuPont on receipt of the Special Cash Payment (subject to certain conditions), (iii) the qualification of the N&B Distribution as a distribution described in Section 355 and to which Section 355(e) does not apply and (iv) the qualification of the Mergers as a “reorganization” within the meaning of Section 368(a) of the Code. This opinion will be based upon and rely on, among other things, certain facts and assumptions, as well as certain representations, statements and undertakings of DuPont, N&B Inc., IFF and Merger Sub 1 and Merger Sub II. If any of these representations, statements or undertakings are, or become, inaccurate or incomplete, or if any party breaches any of its covenants in the relevant transaction documents, the opinion may be invalid and the conclusions reached therein could be jeopardized. Notwithstanding the receipt of such opinion, the Internal Revenue Service (the “IRS”) could determine that the separation of DuPont’s Nutrition & Biosciences business should be treated as a taxable transaction if it determines that any of the facts, assumptions, representations, statements or undertakings upon which the opinion of counsel was based are false or have been violated, or if it disagrees with the conclusions in the opinion. An opinion of counsel is not binding on the IRS and there can be no assurance that the IRS will not assert a contrary position.

If the Contribution, N&B Distribution and Special Cash Payment failed to qualify for the treatment described above, DuPont would be required to generally recognize taxable gain on the transactions and stockholders of DuPont who receive N&B Inc. Common Stock (and subsequently, IFF Common Stock) pursuant to a pro-rata dividend distribution or an exchange offer would be subject to tax on their receipt of the N&B Inc. Common Stock. Additionally, if certain internal transactions related to the separation of the Nutrition & Biosciences business fail to qualify for their intended tax-free treatment under U.S. federal, state, local tax and/or foreign tax law, DuPont could incur additional tax liabilities.

Under the tax matters agreement to be entered into by DuPont with N&B Inc. and IFF, N&B Inc. or IFF would generally be required to indemnify DuPont for any taxes resulting from the separation of the Nutrition & Biosciences business (and any related costs and other damages) to the extent such amounts resulted from (i) certain actions taken by N&B Inc. or IFF involving the capital stock of N&B Inc. or IFF or any assets of the N&B Inc. group (excluding actions required by the documents governing the proposed transactions), or (ii) any breach of certain representations and covenants made by N&B Inc. or IFF.

DuPont is subject to continuing contingent tax-related liabilities of Dow and Corteva following the separations and Distributions.

After the separations and Distributions, there are several significant areas where the liabilities of Dow and Corteva may become the Company’s obligations, either in whole or in part. For example, to the extent that any subsidiary of the Company was included in the consolidated tax reporting group of either Historical Dow or Historical EID for any taxable period or portion of any taxable period ending on or before the effective date of the Merger, such subsidiary is jointly and severally liable for the U.S. federal income tax liability of the entire consolidated tax reporting group of Historical Dow or Historical EID, as applicable, for such taxable period. In connection with the separations and Distributions, DuPont, Dow and Corteva have entered into a Tax Matters Agreement, as amended, that allocates the responsibility for prior period consolidated taxes among Dow, Corteva and DuPont. If Dow or Corteva are unable to pay any prior period taxes for which it is responsible, however, DuPont could be required to pay the entire amount of such taxes, and such amounts could be significant. Other provisions of federal, state, local, or foreign law

19

may establish similar liability for other matters, including laws governing tax-qualified pension plans, as well as other contingent liabilities.

In connection with the separations and Distributions, certain liabilities are allocated to or retained by DuPont through assumption or indemnification of Dow and/or Corteva, as applicable. If DuPont is required to make payments pursuant to these indemnities to Dow and/or Corteva, DuPont may need to divert cash to meet those obligations, and the Company’s financial results could be negatively impacted. In addition, certain liabilities are allocated to or retained by Dow and/or Corteva through assumption or indemnification, or subject to indemnification by other third parties. These indemnities may not be sufficient to insure the Company against the full amount of liabilities, including PFAS Stray Liabilities, allocated to or retained by it, and Dow, Corteva and/or third parties may not be able to satisfy their respective indemnification obligations in the future.

Pursuant to the Separation and Distribution Agreement, the Employee Matters Agreement, and the Tax Matters Agreement, as amended, (collectively, the “Core Agreements”) with Dow and Corteva, as well as the Letter Agreement between DuPont and Corteva, DuPont has agreed to assume, and indemnify Dow and Corteva for, certain liabilities. (See discussion of the Core Agreements in Note 4 to the Consolidated Financial Statements and Litigation and Environmental Matters in Note 16 to the Consolidated Financial Statements.) Payments pursuant to these indemnities may be significant and could negatively impact the Company’s business, particularly indemnities relating to the Company’s actions that could impact the tax-free nature of the distributions. Third parties could also seek to hold it responsible for any of the liabilities allocated to Dow and Corteva, including those related to Historical EID’s materials science and/or agriculture businesses, or for the conduct of such businesses prior to the distributions, and such third parties could seek damages, other monetary penalties (whether civil or criminal) and/or other remedies. Additionally, DuPont generally assumes and is responsible for the payment of the Company’s share of (i) certain liabilities of DowDuPont relating to, arising out of or resulting from certain general corporate matters of DuPont and (ii) certain separation expenses not otherwise allocated to Corteva or Dow (or allocated specifically to it) pursuant to the Core Agreements, and third parties could seek to hold it responsible for Dow’s or Corteva’s share of any such liabilities. Dow and/or Corteva, as applicable, have agreed to indemnify it for such liabilities; however, such indemnities may not be sufficient to protect it against the full amount of such liabilities or from other remedies, and Dow and/or Corteva, as applicable, may not be able to fully satisfy their indemnification obligations. Even if DuPont ultimately succeeds in recovering from Dow and/or Corteva, as applicable, any amounts for which DuPont are held liable, DuPont may be temporarily required to bear these losses. Each of these risks could negatively affect the Company’s business, financial condition, results of operations and cash flows.

Generally, as described in Litigation and Environmental Matters, losses related from liabilities related to discontinued and/or divested operations and businesses of Historical EID that are not primarily related to its agriculture business or specialty products business, (“Stray Liabilities”), are allocated to or shared by each of Corteva and DuPont. Stray Liabilities include liabilities arising out of actions to the extent related to or resulting from Historical EID’s development, testing, manufacture or sale of per- or polyfluoroalkyl substances, (“PFAS Stray Liabilities”). In connection with Historical EID’s separation of its Performance Chemicals segment through the spinoff of The Chemours Company (“Chemours”), Chemours indemnifies certain PFAS Stray Liabilities as well as other litigation, environmental and other liabilities that arose prior to the Chemours Separation,

Certain Stray Liabilities are subject to third party indemnities, including certain PFAS Stray Liabilities as discussed above and further described in Note 16 to the Consolidated Financial Statements; however, such indemnities may not be sufficient to protect the Company against the full amount of such liabilities or such third parties may refuse or otherwise claim defenses to payment. For example, as described in Note 16 to the Consolidated Financial Statements, on May 13, 2019, Chemours filed suit in the Delaware Court of Chancery against Historical EID, Corteva and the Company in an attempt to limit its responsibility for the litigation and environmental liabilities allocated to and assumed by Chemours under the Chemours Separation Agreement.

Although the Company believes it is remote, there can be no assurance that any such third party would have adequate resources to satisfy its indemnification obligation when due, or, would not ultimately be successful in claiming defenses against payment. Even if recovery from the third party is ultimately successful, DuPont may be temporarily required to bear these losses. Each of these risks could negatively affect the Company’s business, financial condition, results of operations and cash flows.

If the completed distribution of Corteva or Dow, in each case, together with certain related transactions, were to fail to qualify for non-recognition treatment for U.S. federal income tax purposes, then the Company could be subject to significant tax and indemnification liability.

The completed distributions of Corteva and Dow were each conditioned upon the receipt of an opinion from Skadden, Arps, Slate, Meagher & Flom LLP, the Company’s tax counsel, regarding the qualification of the applicable distribution along with certain related transactions as a tax-free transaction under Section 355 and Section 368(a)(1)(D) of the Internal Revenue Code of 1986, as amended (the “Code,” and such opinions, collectively, the “Tax Opinions”). The Tax Opinions relied on certain facts, assumptions, and undertakings, and certain representations from the Company, Dow and Corteva, as applicable, as well as the IRS Ruling (as defined below). Notwithstanding the Tax Opinions and the IRS Ruling, the Internal Revenue Service (the “IRS”) could determine

20

on audit that either, or both, of the distributions and certain related transactions should be treated as taxable transactions if it determines that any of these facts, assumptions, representations or undertakings are not correct or have been violated, or that the distributions should be taxable for other reasons, including if the IRS were to disagree with the conclusions of the Tax Opinions.

Even if a distribution otherwise constituted a tax-free transaction to stockholders under Section 355 of the Code, the Company could be required to recognize corporate level tax on such distribution and certain related transactions under Section 355(e) of the Code if the IRS determines that, as a result of the Merger or other transactions considered part of a plan with such distribution, there was a 50 percent or greater change in ownership in the Company, Dow or Corteva, as relevant. In connection with the Merger, the Company sought and received a private letter ruling from the IRS regarding the proper time, manner and methodology for measuring common ownership in the stock of the Company, Historical EID and Historical Dow for purposes of determining whether there was a 50 percent or greater change of ownership under Section 355(e) of the Code as a result of the Merger (the “IRS Ruling”). The Tax Opinions relied on the continued validity of the IRS Ruling and representations made by the Company as to the common ownership of the stock of Historical Dow and Historical EID immediately prior to the Merger, and concluded that there was not a 50 percent or greater change of ownership for purposes of Section 355(e) as a result of the Merger. Notwithstanding the Tax Opinions and the IRS Ruling, the IRS could determine that a distribution or a related transaction should nevertheless be treated as a taxable transaction to the Company if it determines that any of the Company’s facts, assumptions, representations or undertakings was not correct or that a distribution should be taxable for other reasons, including if the IRS were to disagree with the conclusions in the Tax Opinions that are not covered by the IRS Ruling.

Generally, corporate taxes resulting from the failure of a distribution to qualify for non-recognition treatment for U.S. federal income tax purposes would be imposed on the Company. Under the Tax Matters Agreement, as amended, that the Company entered into with Dow and Corteva, Dow and Corteva are generally obligated to indemnify the Company against any such taxes imposed on it. However, if a distribution fails to qualify for non-recognition treatment for U.S. federal income tax purposes for certain reasons relating to the overall structure of the Merger and the distributions, then under the Tax Matters Agreement, as amended, the Company and Corteva, on the one hand, and Dow, on the other hand, would share the tax liability resulting from such failure in accordance with the relative equity values of the Company and Dow on the first full trading day following the distribution of Dow, and the Company and Corteva would in turn share any such resulting tax liability in accordance with the relative equity values of the Company and Corteva on the first full trading day following the distribution of Corteva. Furthermore, under the terms of the Tax Matters Agreement, as amended, a party also generally will be responsible for any taxes imposed on the other parties that arise from the failure of either distribution to qualify as tax-free for U.S. federal income tax purposes within the meaning of Section 355 of the Code or the failure of certain related transactions to qualify for tax-free treatment, to the extent such failure to qualify is attributable to actions, events or transactions relating to such party, or such party's affiliates’, stock, assets or business, or any breach of such party's representations made in connection with the IRS Ruling or in any representation letter provided to a tax advisor in connection with certain tax opinions, including the Tax Opinions, regarding the tax-free status of the distributions and certain related transactions. To the extent that the Company is responsible for any liability under the Tax Matters Agreement, as amended, there could be a material adverse impact on the Company's business, financial condition, results of operations and cash flows in future reporting periods.

The separations and Distributions may expose the Company to potential liabilities arising out of state and federal fraudulent conveyance laws and legal distribution requirements.

Although DuPont received a solvency opinion from an investment bank confirming that DuPont, Dow and Corteva would each be adequately capitalized following the separations and Distributions, the separations and Distributions could be challenged under various state and federal fraudulent conveyance laws. Fraudulent conveyances or transfers are generally defined to include transfers made or obligations incurred with the actual intent to hinder, delay or defraud current or future creditors or transfers made or obligations incurred for less than reasonably equivalent value when the debtor was insolvent, or that rendered the debtor insolvent, inadequately capitalized or unable to pay its debts as they become due. Any unpaid creditor could claim that DuPont did not receive fair consideration or reasonably equivalent value in the separations and distributions, and that the separations and distributions left DuPont insolvent or with unreasonably small capital or that DuPont intended or believed DuPont would incur debts beyond the Company’s ability to pay such debts as they mature. If a court were to agree with such a plaintiff, then such court could void the separations and distributions as a fraudulent transfer or impose substantial liabilities on it, which could adversely affect the Company’s financial condition and the Company’s results of operations.

The separations and Distributions are also subject to review under state corporate distribution statutes. Under the Delaware General Corporation Law, a corporation may only pay dividends to its stockholders either (i) out of its surplus (net assets minus capital) or (ii) if there is no such surplus, out of its net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. Although DuPont’s Board of Directors made the distributions out of DuPont’s surplus and received an opinion that DuPont had adequate surplus under Delaware law to declare the dividends of Corteva and Dow common stock in connection with the Distributions, there can be no assurance that a court will not later determine that some or all of the distributions were unlawful.

Risks Relating to DuPont’s Business

Changes in the Company’s credit ratings could increase the Company’s cost of borrowing or restrict the Company’s ability to access debt capital markets. The Company’s credit ratings are important to the Company’s cost of capital.

DuPont relies on access to the debt capital markets and other short-term borrowings to finance the Company’s long-term and day-to-day operations. A decrease in the ratings assigned to it by the ratings agencies may negatively impact the Company’s access to the debt capital markets and increase the Company’s cost of borrowing. The major rating agencies will routinely evaluate the Company’s credit profile and assign debt ratings to it. This evaluation is based on a number of factors, which include weighing the Company’s financial strength versus business, industry and financial risk. The addition of further leverage to the Company’s capital structure could impact the Company’s credit ratings. Failure to maintain an investment grade rating at the Company’s current level would adversely affect the Company’s cost of funding and the Company’s results of operations and could adversely affect the Company’s liquidity and access to the capital markets. Any limitation on the Company’s ability to continue to raise money in the debt capital markets could have a substantial negative effect on the Company’s liquidity. If DuPont is unable to generate sufficient cash flow or maintain access to adequate external financing, including from significant disruptions in the global credit markets, it could restrict the Company’s current operations, activities under its current and future stock buyback programs, and the Company’s growth opportunities, which could adversely affect the Company’s operating results.

A significant percentage of the Company’s net sales are generated from the Company’s international operations and are subject to economic, political, regulatory, foreign exchange and other risks.

The percentage of net sales generated by the international operations of DuPont, including U.S. exports, was approximately 70 percent of net sales on a continuing operations basis for the year ended December 31, 2019. With Asia Pacific as the Company’s largest region, DuPont expects the percentage of the Company’s net sales derived from international operations to continue to be significant. Risks related to international operations include:

• difficulties and costs associated with complying with a wide variety of complex, and often conflicting, laws, treaties and regulations, including antitrust regulations;

• restrictions on, as well as difficulties and costs associated with, the repatriation of cash from foreign countries to the United States and the allocation of revenues or distributions of cash between the Company’s foreign subsidiaries;

• exchange control regulations;

• fluctuations in foreign exchange rates;

• labor compliance costs, including wage, salary and benefit controls and other costs associated with a global workforce, as will as difficulties in hiring and maintaining a qualified staff outside of the United States, especially in the Asia Pacific region;

• government mandated price controls;

• foreign investment laws;

• potential for changes in global trade policies, including import, export and other trade restrictions (such as sanctions and embargoes) and tariffs;

• trends such as populism, economic nationalism and negative sentiment toward multinational companies, as well as government takeover or nationalization of businesses; and

• instability and uncertainty arising from the global geopolitical environment and the evolving international and domestic political, regulatory and economic landscape.

These and other factors can impair the Company’s flexibility in modifying product, marketing, pricing or other strategies for growing the Company’s businesses, as well as the Company’s ability to improve productivity and maintain acceptable operating margins.

The Company’s international operations expose it to fluctuations in foreign currencies relative to the U.S. dollar, which could adversely affect the Company’s results of operations. For its continuing operations as of the year ended December 31, 2019, the Company’s largest currency exposures are the Chinese renminbi and the Taiwan dollar. U.S. dollar fluctuations against foreign currency have an impact to commercial prices and raw material costs in some cases and could result in local price increases if the price or raw material costs is denominated in U.S. dollar.

Sales and expenses of the Company’s non-U.S. businesses are also translated into U.S. dollars for reporting purposes and fluctuations of foreign currency against the U.S. dollar could impact U.S. dollar-denominated earnings. In addition, the Company’s assets and liabilities denominated in foreign currencies can also be impacted by foreign currency exchange rates against the U.S. dollar, which could result in exchange gain or loss from revaluation.

DuPont also faces exchange rate risk from the Company’s investments in subsidiaries owned and operated in foreign countries.

22

DuPont has a balance sheet hedging program and actively looks for opportunities in managing currency exposures related to earnings. However, foreign exchange hedging activities bear a financial cost and may not always be available to it or be successful in completely mitigating such exposures.

DuPont generates significant amounts of cash outside of the United States that is invested with financial and non-financial counterparties. While DuPont employs comprehensive controls regarding global cash management to guard against cash or investment loss and to ensure the Company’s ability to fund the Company’s operations and commitments, a material disruption to the counterparties with whom DuPont transacts business could expose it to financial loss.

Any one or more of the above factors could adversely affect the Company’s international operations and could significantly affect the Company’s business, results of operations, financial condition and cash flows.

Volatility in energy and raw material costs could have a significant impact on the Company’s sales and earnings.

The Company’s manufacturing processes consume significant amounts of energy and raw materials, the costs of which are subject to worldwide supply and demand as well as other factors beyond the Company’s control. Significant variations in the cost of energy, which primarily reflect market prices for oil, natural gas and raw materials, affect the Company’s operating results from period to period. Legislation to address climate change by reducing greenhouse gas emissions, creating a carbon tax or implementing a cap and trade program could create increases in energy costs and price volatility.

When possible, DuPont purchases raw materials through negotiated long-term contracts to minimize the impact of price fluctuations. Additionally, DuPont uses over-the-counter and exchange traded derivative commodity instruments to hedge the Company’s exposure to price fluctuations on certain raw material purchases, including food ingredients. DuPont also takes actions to offset the effects of higher energy and raw material costs through selling price increases, productivity improvements and cost reduction programs. Success in offsetting higher raw material costs with price increases is largely influenced by competitive and economic conditions and could vary significantly depending on the market served. As a result, volatility in these costs may negatively impact the Company’s business, results of operations, financial condition and cash flows.

The Company’s results will be affected by competitive conditions and customer preferences.

Demand for the Company’s products, which impacts revenue and profit margins, will be affected by (i) the development and timing of the introduction of competitive products; (ii) the Company’s response to downward pricing trends to stay competitive; (iii) changes in customer order patterns, such as changes in the levels of inventory maintained by customers and the timing of customer purchases which may be affected by announced price changes, changes in the Company’s incentive programs, or the customer’s ability to achieve incentive goals; (iv) the impact of tariffs or trade disputes on availability of raw materials; and (v) changes in customers’ preferences for the Company’s products, including the success of products offered by the Company’s competitors, and changes in customer’s designs for their products that can affect the demand for some of the Company’s products.

Additionally, success in achieving the Company’s growth objectives is significantly dependent on the timing and market acceptance of the Company’s new product offerings, including the Company’s ability to renew the Company’s pipeline of new product offerings and to bring those offerings to market. This ability may be adversely affected by difficulties or delays in product development, such as the inability to identify viable new products, obtain adequate intellectual property protection, or gain market acceptance of new products. There are no guarantees that new products will prove to be commercially successful. The Company’s success will depend on several factors, including the Company’s ability to:

• correctly identify customer needs and preferences and predict future needs and preferences;

• allocate the Company’s research & development funding to products and services with higher growth prospects;

• anticipate and respond to the Company’s competitors’ development of new products and services and technological innovations;

• differentiate the Company’s offerings from the Company’s competitors’ offerings and avoid commoditization;

• innovate and develop new technologies and applications, and acquire or obtain rights to third-party technologies that may have valuable applications in the Company’s served markets;

• obtain adequate intellectual property rights with respect to key technologies before the Company’s competitors do;

• successfully commercialize new technologies in a timely manner, price them competitively and cost-effectively manufacture and deliver sufficient volumes of new products of appropriate quality on time;

• obtain necessary regulatory approvals of appropriate scope; and

• stimulate customer demand for, and convince customers, to adopt new technologies.

There are no guarantees that new product offerings will prove to be commercially successful. Additionally, the Company’s expansion into new markets may result in greater-than-expected risks, liabilities and expenses.

23

The costs of complying with evolving regulatory requirements could negatively impact the Company’s business, results of operations, financial condition and cash flows. Actual or alleged violations of environmental laws or permit requirements could result in restrictions or prohibitions on plant operations and substantial civil or criminal sanctions, as well as the assessment of strict liability and/or joint and several liability.

DuPont continues to be subject to extensive federal, state, local and foreign laws, regulations, rules and ordinances relating to pollution, protection of the environment, greenhouse gas emissions, and the generation, storage, handling, transportation, treatment, disposal and remediation of hazardous substances and waste materials. Costs and capital expenditures relating to environmental, health or safety matters are subject to evolving regulatory requirements and depend on the timing of the promulgation and enforcement of specific standards which impose the requirements. Moreover, changes in environmental regulations could inhibit or interrupt the Company’s operations, or require modifications to the Company’s facilities. Changes to regulations or the implementation of additional regulations, especially in certain highly regulated markets served by the Company’s Nutrition & Biosciences businesses, such as regulatory modernization of food safety laws and evolving standards and regulations affecting pharmaceutical excipients, microbials, or in reaction to new or next-generation technologies, including advances in protein engineering, gene editing and gene mapping, or novel uses of existing technologies may result in significant costs or capital expenditures or require changes in business practice that could result in reduced margins or profitability.

Accordingly, environmental, health or safety regulatory matters could result in significant unanticipated costs or liabilities causing a negative impact on the Company’s business, cash flows and results of operations.

The Company’s business, results of operations and reputation could be adversely affected by industry-specific risks including process safety and product stewardship/regulatory compliance issues.

DuPont is subject to risks which include, but are not limited to, product safety or quality; shifting consumer preferences; federal, state, and local regulations on manufacturing or labeling; environmental, health and safety regulations; and customer product liability claims. While DuPont maintains general liability insurance, the amount of liability that may result from certain of these risks may not always be covered by, or could exceed, the applicable insurance coverage. In addition, negative publicity related to product liability, food safety, safety, health and environmental matters may damage the Company’s reputation. The occurrence of any of the matters described above could adversely affect the Company’s business, results of operations, financial condition and cash flows.

In most jurisdictions, DuPont must test the safety, efficacy and environmental impact of the Company’s products to satisfy regulatory requirements and obtain the needed approvals. In certain jurisdictions, DuPont must periodically renew the Company’s approvals, which may require it to demonstrate compliance with then-current standards. The regulatory approvals process is lengthy, complex and in some markets unpredictable, with requirements that can vary by product, technology, industry and country. Additionally, the regulatory environment may be impacted by the activities of non-governmental organizations and special interest groups and stakeholder reactions to the actual or perceived impacts of new technology, products or processes on safety, health and the environment. Obtaining and maintaining regulatory approvals will require submitting a significant amount of information and data, which may require participation from technology providers. Regulatory standards and trial procedures are continuously changing. The pace of change together with the lack of regulatory harmony could result in unintended noncompliance. To maintain the Company’s right to produce or sell existing products or to commercialize new products, DuPont must be able to demonstrate the Company’s ability to satisfy the requirements of regulatory agencies.

The failure to meet existing and new requirements or receive necessary permits or approvals could have near- and long-term effects on the Company’s ability to produce and sell certain current and future products, which could significantly increase operating costs and adversely affect the Company’s business, results of operations, financial condition and cash flows.

The Company’s business, results of operations, financial condition and cash flows could be adversely affected by interruption of the Company’s supply chain, information technology or network systems and other business disruptions.

Supply chain disruptions, plant and/or power outages, labor disputes and/or strikes, information technology system and/or network disruptions, whether caused by acts of sabotage, employee error, malfeasance or other actions, geo-political activity, weather events and natural disasters, including hurricanes or flooding that impact coastal regions, and global health risks or pandemics could seriously harm the Company’s operations as well as the operations of the Company’s customers and suppliers. In addition, terrorist attacks and natural disasters have increased stakeholder concerns about the security and safety of chemical production and distribution.

Supply chain and other business disruptions may also be caused by security breaches, which could include, for example, attacks on information technology and infrastructure by hackers, viruses, breaches due to employee error, malfeasance or other actions or other disruptions. DuPont and/or the Company’s suppliers may fail to effectively prevent, detect and recover from these or other security breaches and, therefore, such breaches could result in misuse of the Company’s assets, loss of property including trade secrets and confidential or personal information, some of which is subject to privacy and security laws, and other business

24

disruptions. As a result, DuPont may be subject to legal claims or proceedings, reporting errors, processing inefficiencies, negative media attention, loss of sales, interference with regulatory compliance which could result in sanctions or penalties, liability or penalties under privacy laws, disruption in the Company’s operations, and damage to the Company’s reputation, which could adversely affect the Company’s business, results of operations, financial condition and cash flows.

Like most major corporations, DuPont is the target of industrial espionage, including cyber-attacks, from time to time. DuPont has determined that these attacks have resulted, and could result in the future, in unauthorized parties gaining access to certain confidential business information. Although management does not believe that DuPont has experienced any material losses to date related to these security breaches, including cybersecurity incidents, there can be no assurance that DuPont will not suffer such losses in the future.

DuPont seeks to actively manage the risks within the Company’s control that could lead to business disruptions and security breaches. As these threats continue to evolve, particularly around cybersecurity, DuPont may be required to expend significant resources to enhance the Company’s control environment, processes, practices and other protective measures. Despite these efforts, such events could have a material adverse effect on the Company’s business, results of operations, financial condition and cash flows.

Enforcing the Company’s intellectual property rights, or defending against intellectual property claims asserted by others, could adversely affect the Company’s business, results of operations, financial condition and cash flows.

Intellectual property rights, including patents, trade secrets, know-how and other confidential information, trademarks, tradenames and other forms of trade dress, are important to the Company’s business. DuPont endeavors to protect the Company’s intellectual property rights in jurisdictions in which the Company’s products are produced or used and in jurisdictions into which the Company’s products are imported. However, DuPont may be unable to obtain protection for the Company’s intellectual property in key jurisdictions. Further, changes in government policies and regulations, including changes made in reaction to pressure from non-governmental organizations, or the public generally, could impact the extent of intellectual property protection afforded by such jurisdictions.

DuPont has designed and implemented internal controls intended to restrict access to and distribution of the Company’s intellectual property. Despite these precautions, the Company’s intellectual property is vulnerable to unauthorized access through employee error or actions, theft and cybersecurity incidents, and other security breaches. When unauthorized access and use or counterfeit products are discovered, DuPont considers the matter for report to governmental authorities for investigation, as appropriate, and take measures to mitigate any potential impact. Protecting intellectual property related to biotechnology is particularly challenging because theft is difficult to detect and biotechnology can be self-replicating. Accordingly, the impact of such theft can be significant.

Competitors are increasingly challenging the Company’s intellectual property positions, and the potential outcomes can be highly uncertain. Third parties may also claim the Company’s products violate their intellectual property rights. Defending such claims, even those without merit, is time-consuming and expensive. In addition, as a result of such claims, DuPont has and could be required in the future to enter into license agreements, develop non-infringing products or engage in litigation that could be costly. If challenges are resolved adversely, it could negatively impact the Company’s ability to obtain licenses on competitive terms, commercialize new products and generate sales from existing products.

In addition, because of the rapid pace of technological change, the confidentiality of patent applications in some jurisdictions and/or the uncertainty in predicting the outcome of complex proceedings relating to ownership or the scope of protection of patents relating to certain emerging technologies, competitors may be unexpectedly issued patents that DuPont does not anticipate. These patents could reduce the value of the Company’s commercial or pipeline products or, to the extent they cover key technologies on which DuPont has unknowingly relied, require it to seek to obtain licenses or cease using the technology, no matter how valuable to the Company’s business. If DuPont decided to obtain licenses to continue using the technology, it cannot ensure DuPont would be able to obtain such a license on acceptable terms.

Legislation and jurisprudence on patent protection is evolving, and changes in laws could affect the Company’s ability to obtain or maintain patent protection for the Company’s products.

Any one or more of the above factors could significantly affect the Company’s business, results of operations, financial condition and cash flows.

25

Increased concerns regarding chemicals in commerce and their potential impact on the environment have resulted in more restrictive regulations, may lead to new regulations and compliance may be costly.

Concerns about chemicals and biotechnology, as well as their potential impact on health and the environment, reflect a growing trend in societal demands for increasing levels of product safety and environmental protection. These concerns could manifest themselves in stockholder proposals, preferred purchasing, delays or failures in obtaining or retaining regulatory approvals, delayed product launches, lack of market acceptance, product discontinuation, continued pressure for and adoption of more stringent regulatory intervention and litigation. These concerns could also influence public perceptions, the viability or continued sales of certain of the Company’s products, the Company’s reputation and the cost to comply with regulations and, as a result, could have a negative impact on the Company’s business, results of operations and financial condition.

An impairment of goodwill or intangible assets could negatively impact the Company’s financial results.

At least annually, DuPont must assess both goodwill and indefinite-lived intangible assets for impairment. Intangible assets with finite lives are tested for impairment when events or changes in circumstances indicate their carrying value may not be recoverable. If testing indicates that goodwill or intangible assets are impaired, their carrying values will be written down based on fair values with a charge against earnings. Where DuPont utilizes discounted cash flow methodologies in determining fair values, continued weak demand for a specific product line or business could result in an impairment. Accordingly, any determination requiring the write-off of a significant portion of goodwill or intangible assets could negatively impact the Company’s results of operations.

As a result of the Merger and related acquisition method of accounting, Historical EID’s assets and liabilities were measured at fair value, and any declines in projected cash flows could have a material, negative impact on the fair value of the Company’s reporting units and assets. Future impairments of the Company’s goodwill or intangible assets also could be recorded due to changes in assumptions, estimates or circumstances and the magnitude of such impairments may be material to it.

Failure to effectively manage acquisitions, divestitures, alliances and other portfolio actions could adversely impact the Company’s business, results of operations, financial condition and cash flows.

DuPont from time to time evaluates acquisition candidates that may strategically fit the Company’s business and/or growth objectives. If DuPont is unable to successfully integrate and develop acquired businesses, DuPont could fail to achieve anticipated synergies and cost savings, including any expected increases in revenues and operating results, which could have a material adverse effect on the Company’s financial results. DuPont expects to continually review the Company’s portfolio of assets for contributions to the Company’s objectives and alignment with the Company’s growth strategy. The Letter Agreement between the Company and Corteva limits DuPont’s ability to separate certain businesses and assets to third parties without assigning certain of its indemnification obligations under the Separation and Distribution Agreement to the transferee of such businesses and assets or meeting certain other alternative conditions. DuPont may be unable to meet the conditions under the Letter Agreement, if applicable. Even if the conditions under the Letter Agreement are met or are not applicable, DuPont may not be successful in separating underperforming or non-strategic assets, and gains or losses on the divestiture of, or lost operating income from, such assets may affect the Company’s earnings. Moreover, DuPont might incur asset impairment charges related to acquisitions or divestitures that reduce the Company’s earnings. In addition, if the execution or implementation of acquisitions, divestitures, alliances, joint ventures and other portfolio actions is not successful and/or the Company fails to effectively manage its cost as its portfolio evolves, it could adversely impact the Company’s business, results of operations, financial condition and cash flows.

The Company’s results of operations could be adversely affected by litigation and other commitments and contingencies.

DuPont faces risks arising from various unasserted and asserted litigation matters, including product liability, patent infringement and other intellectual property disputes, contract and commercial litigation, claims for damage or personal injury, antitrust claims, governmental regulations and other actions. An adverse outcome in any one or more of these matters could be material to the Company’s business, results of operations, financial condition and cash flows.

In the ordinary course of business, DuPont may make certain commitments, including representations, warranties and indemnities relating to current and past operations, including those related to divested businesses, and DuPont may issue guarantees of third-party obligations. If DuPont is required to make payments as a result, they could exceed the amounts accrued therefor, thereby adversely affecting the Company’s results of operations.

DuPont is subject to numerous laws, regulations and mandates globally which could adversely affect the Company’s operating results and forward strategy.

DuPont does business globally in more than 60 countries. DuPont is required to comply with the numerous and far-reaching laws and regulations administered by United States federal, state, local and foreign governmental authorities. DuPont is required to comply with other general business regulations covering areas such as income taxes, anti-corruption, anti-bribery, global trade, trade sanctions, environmental protections, product safety, and handling and production of regulated substances. DuPont expects to frequently face challenges from U.S. and foreign tax authorities regarding the amount of taxes due. These challenges may include questions regarding the timing and amount of deductions and the allocation of income among various tax jurisdictions.

26

In evaluating the exposure associated with various tax filing positions, DuPont expects to record reserves for estimates of potential additional tax DuPont may owe. Any failure to comply with applicable laws and regulations or appropriately resolve these challenges could subject it to administrative, civil and criminal remedies including fines, penalties, disgorgement, injunctions and recalls of the Company’s products, and damage to the Company’s reputation.

Governmental policies, including antitrust and competition law, trade restrictions, regulations related to medical applications and devices, food safety regulations, sustainability requirements, traceability and other government regulations and mandates, can impact the Company’s ability to execute this strategy successfully. See also “A significant percentage of the Company’s net sales are generated from the Company’s international operations and are subject to the economic, political, regulatory, foreign exchange and other risks.”

Failure to maintain a streamlined operating model and sustain operational improvements may reduce the Company’s profitability or adversely impact the Company’s business, results of operations, financial condition and cash flows.

The Company’s profitability and margin growth will depend in part on the Company’s ability to maintain a streamlined operating model and drive sustainable improvements, through actions and projects, such as consolidation of manufacturing facilities, transitions to cost-competitive regions and product line rationalizations. A variety of factors may adversely affect the Company’s ability to realize the targeted cost synergies, including failure to successfully optimize the Company’s facilities footprint, the failure to take advantage of the Company’s global supply chain, the failure to identify and eliminate duplicative programs, and the failure to otherwise integrate Historical EID’s or Historical Dow’s respective specialty products businesses, including their technology platforms. There can be no assurance that DuPont is be able to achieve or sustain any or all of the cost savings generated from restructuring actions.

The Company’s U.S. and non-U.S. tax liabilities will be dependent, in part, upon the distribution of income among various jurisdictions in which DuPont operates.

The Company’s future results of operations could be adversely affected by changes in the effective tax rate as a result of a change in the mix of earnings in countries with differing statutory tax rates, changes in tax laws, regulations and judicial rulings (or changes in the interpretation thereof), changes in generally accepted accounting principles, changes in the valuation of deferred tax assets and liabilities, changes in the amount of earnings permanently reinvested offshore, the results of audits and examinations of previously filed tax returns and continuing assessments of the Company’s tax exposures and various other governmental enforcement initiatives. The Company’s tax expense includes estimates of tax reserves and reflects other estimates and assumptions, including assessments of future earnings of the Company which could impact the valuation of the Company’s deferred tax assets. Changes in tax laws or regulations, including further regulatory developments arising from U.S. tax reform legislation as well as multi-jurisdictional changes enacted in response to the action items provided by the Organization for Economic Co-operation and Development (OECD), will increase tax uncertainty and impact the Company’s provision for income taxes.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Effective August 31, 2017, pursuant to the merger of equals transactions contemplated by the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017 ("DWDP Merger Agreement"), The Dow Chemical Company ("Historical Dow") and E. I. du Pont de Nemours and Company ("Historical EID") each merged with subsidiaries of DowDuPont Inc. ("DowDuPont") and, as a result, Historical Dow and Historical EID became subsidiaries of DowDuPont (the "Merger"). Prior to the Merger, DowDuPont did not conduct any business activities other than those required for its formation and matters contemplated by the DWDP Merger Agreement. Historical Dow was determined to be the accounting acquirer in the Merger.

As discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, DowDuPont previously announced its intent to separate into three, independent, publicly traded companies - one for each of its agriculture, materials science and specialty products businesses. DowDuPont formed two wholly owned subsidiaries: Dow Inc. ("Dow", formerly known as Dow Holdings Inc.), to serve as a holding company for its materials science business, and Corteva, Inc. ("Corteva"), to serve as a holding company for its agriculture business.

Effective as of 5:00 p.m. on April 1, 2019, DowDuPont completed the separation of its materials science business into a separate and independent public company by way of a distribution of Dow through a pro rata dividend in-kind of all of the then-issued and outstanding shares of Dow’s common stock, par value $0.01 per share (the “Dow Common Stock”), to holders of the Company’s common stock, par value $0.01 per share (the “DowDuPont common stock”), as of the close of business on March 21, 2019 (the “Dow Distribution”).

Effective as of 12:01 a.m. on June 1, 2019, DuPont de Nemours, Inc. (formerly known as DowDuPont Inc.), completed the separation of its agriculture business into a separate and independent public company by way of a distribution of Corteva through a pro rata dividend in-kind of all of the then-issued and outstanding shares of Corteva’s common stock, par value $0.01 per share (the “Corteva Common Stock”), to holders of the Company’s common stock, par value $0.01 per share, as of the close of business on May 24, 2019 (the “Corteva Distribution” and, together with the Dow Distribution, the “Distributions”).

Following the Corteva Distribution, the Company holds the specialty products business. On June 1, 2019, DowDuPont changed its registered name from "DowDuPont Inc." to "DuPont de Nemours, Inc." doing business as "DuPont" (the "Company"). Beginning on June 3, 2019, the Company's common stock is traded on the NYSE under the ticker symbol "DD".

These Consolidated Financial Statements present the consolidated financial position of DuPont as of December 31, 2019 and December 31, 2018 and the results of operations of DuPont for the years ended December 31, 2019, 2018 and 2017 giving effect to the Distributions, with the historical financial results of Dow and Corteva reflected as discontinued operations. The cash flows related to Dow and Corteva have not been segregated and are included, as applicable, in the Consolidated Statements of Cash Flows for all periods presented. Unless otherwise indicated, the information included in Management's Discussion and Analysis refer only to DuPont's continuing operations and do not include discussion of balances or activity of Dow or Corteva.

The statements of operations and pro forma statements of operations included in this report and as discussed below include costs previously allocated to the materials science and agriculture businesses that did not meet the definition of expenses related to discontinued operations in accordance with Financial Accounting Standards Codification 205, "Presentation of Financial Statements" ("ASC 205") and thus are reflected in the Company's results of continuing operations. A significant portion of these costs relate to Historical Dow and consist of leveraged services provided through service centers, as well as other corporate overhead costs related to information technology, finance, manufacturing, research & development, sales & marketing, supply chain, human resources, sourcing & logistics, legal and communications, public affairs & government affairs functions. These costs are no longer incurred by the Company following the Distributions.

ANALYSIS OF OPERATIONS

Portfolio Changes: Business Separations and Distribution

Intended Nutrition & Biosciences Separation

DuPont and International Flavors & Fragrances Inc. ("IFF") announced on December 15, 2019, the entry into a definitive agreement for the merger of IFF and DuPont’s Nutrition & Biosciences business (the "N&B Business"). The combination will be executed through a Reverse Morris Trust transaction (the "Proposed N&B Transaction"). The Proposed N&B Transaction is expected to be tax-free to DuPont and its shareholders for U.S. federal income tax purposes. Upon completion of the proposed transaction with IFF, DuPont shareholders will own 55.4% of the combined company and IFF’s shareholders will own 44.6%. In addition, as part of the proposed transaction, DuPont will receive a one-time $7.3 billion cash payment, subject to adjustment, (the “Special Cash Payment”). The Special Cash Payment is subject to adjustment due to, among other things, variances in net working capital, and, therefore, could be less or more than anticipated. The Proposed N&B Transaction is expected to close by the end of the first quarter of 2021, subject to approval by IFF stockholders and other customary closing conditions, including regulatory approvals and receipt by DuPont of an opinion of tax counsel. See Item 1 for additional information. See discussion of Nutrition & Biosciences Financing under Liquidity & Capital Resources below for information regarding actions in connection with the Proposed N&B Transaction and Special Cash Payment.

Dow and Corteva Distributions

In connection with the Dow Distribution and Corteva Distribution, DuPont has entered into certain agreements that provide for the allocation of DuPont’s assets, employees, liabilities and obligations (including its investments, property, employee benefits and tax-related assets and liabilities) among DuPont, Dow, and Corteva (together, the “Parties” and each a “Party”), and provides a framework for DuPont’s relationship with Dow and Corteva following the Distributions.

In addition to the agreements above, DuPont has entered into certain various supply agreements with Dow. These agreements provide for different pricing than the historical intercompany and intracompany practices prior to the Distributions.

Effective June 1, 2019, in connection with the Corteva Distribution, DuPont and Corteva entered into the following agreements:

• Intellectual Property Cross-License Agreement - DuPont and Corteva entered into an Intellectual Property Cross-License Agreement (the “DuPont-Corteva IP Cross-License Agreement”). The DuPont-Corteva IP Cross-License Agreement sets forth the terms and conditions under which the applicable parties may use in their respective businesses, following the Corteva Distribution, certain know-how (including trade secrets), copyrights, software, and certain patents and standards, allocated to another Party pursuant to the Separation and Distribution Agreement.

• Letter Agreement - The Company entered into a letter agreement (the "Letter Agreement") with Corteva that sets forth certain additional terms and conditions related to the Corteva Distribution, including certain limitations on DuPont’s and Corteva's ability to transfer certain businesses and assets to third parties without assigning certain of such Party’s indemnification obligations under the Separation and Distribution Agreement to the other Party to the transferee of such businesses and assets or meeting certain other alternative conditions. The Letter Agreement further outlines the allocation between DuPont and Corteva of liabilities associated with certain legal and environmental matters, including liabilities associated with discontinued and/or divested operations and businesses of Historical EID. See Note 16 to the Consolidated Financial Statements for more information regarding the allocation.

34

• Amended and Restated Tax Matters Agreement - The Parties entered into an amendment and restatement of the Tax Matters Agreement, between DuPont, Corteva and Dow, effective as of April 1, 2019 (as so amended and restated, the “Amended and Restated Tax Matters Agreement”). The Amended and Restated Tax Matters Agreement governs the Parties’ rights, responsibilities and obligations with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and other matters regarding taxes. The Parties amended and restated the Tax Matters Agreement in connection with the Corteva Distribution in order to allocate between the DuPont and Corteva certain rights and obligations of the Company provided in the original form of the Tax Matters Agreement.

Other Divestitures

In the third quarter of 2019, the Company completed the sale and separation of its Sustainable Solutions business unit, a part of the Non-Core segment, to Gyrus Capital. The sale resulted in a pre-tax gain of $28 million ($22 million net of tax) which was recorded in "Sundry income (expense) - net" in the Company's Consolidated Statements of Operations.

In September 2019, DuPont announced an agreement to sell its compound semiconductor solutions business, a part of the Electronics & Imaging segment, to SK Siltron for approximately $450 million. The transaction is expected to close in the first quarter of 2020, pending satisfaction of customary closing conditions, including receipt of regulatory approval.

2019 versus 2018

The Company reported net sales for the year ended December 31, 2019 of $21.5 billion, down 5 percent from $22.6 billion for the year ended December 31, 2018, due to a 4 percent decrease in volume, a 2 percent unfavorable currency impact and a 1 percent decline in portfolio actions slightly offset by a 2 percent increase in local price. Volume declined across all geographic regions and all segments with the exception of Nutrition & Biosciences and Safety & Construction which were both flat. The most notable volume decreases were in Non-Core (down 11 percent) and Transportation & Industrial (down 10 percent). Currency was down 2 percent compared with last year, driven primarily by EMEA currencies (down 5 percent). Local price was up 2 percent compared with last year. Local price increased in all geographic regions and in all segments except Electronics & Imaging (flat). Portfolio and other changes contributed 1 percent of the sales decrease which impacted Safety & Construction (down 4 percent; within EMEA), Non-Core (down 3 percent) and Nutrition & Biosciences (down 1 percent).

2018 versus 2017

Net sales for the year ended December 31, 2018 were $22.6 billion, up 94 percent from $11.7 billion for the year ended December 31, 2017, due to a 91 percent increase in portfolio actions, primarily reflecting the Merger, a 2 percent increase in local price and a 1 percent increase in volume. Volume increases in Electronics & Imaging (up 4 percent), Safety & Construction (up 2 percent) and Nutrition & Biosciences (up 1 percent) more than offset volume declines in Non-Core (down 4 percent) and Transportation & Industrial (down 2 percent). Local price was up 2 percent compared with the prior year. Local price increased in all geographic regions and in most segments except Electronics & Imaging (down 1 percent) and Non-core (flat). Currency was flat compared with the prior year.

2018 versus 2017 (Pro Forma)

Net sales for the year ended December 31, 2018 were $22.6 billion, up 8 percent from pro forma net sales of $21.0 billion for the year ended December 31, 2017, due to a 3 percent increase in volume, a 2 percent increase in portfolio actions, a 2 percent increase in local price, and a 1 percent favorable currency impact. Volume increased across most geographic regions, except EMEA (flat), and in most segments with the exception of Non-Core (down 3 percent). Volume increases were in Electronics & Imaging (up 4 percent), Nutrition & Biosciences (up 3 percent), Safety & Construction (up 3 percent) and Transportation & Industrial (up 2 percent). Portfolio and other changes increased 2 percent primarily due to a 11 percent increase in Nutrition and Biosciences related to the acquisition of FMC’s Health & Nutrition business. Local price was up 2 percent compared with the prior year. Local price increased in all geographic regions and in most segments except Electronics & Imaging (down 1 percent). Currency was up 1 percent compared with prior year, driven by EMEA currencies (up 5 percent) which was partially offset by Latin America currencies (down 4 percent).

Cost of Sales

Cost of sales was $14.1 billion for the year ended December 31, 2019, down from $15.3 billion for the year ended December 31, 2018. Cost of sales decreased for the year ended December 31, 2019 primarily due to lower sales volume, cost synergies, portfolio actions related to current year divestitures, currency impacts, and lower costs previously allocated to the materials science and agriculture businesses that did not meet the definition of expenses related to discontinued operations in accordance with ASC 205 and therefore remained as costs of continuing operations for periods prior to the Distributions.

Cost of sales as a percentage of net sales for the year ended December 31, 2019 was 65 percent compared with 68 percent for the year ended December 31, 2018.

For the year ended December 31, 2018, cost of sales was $15.3 billion, up from $9.6 billion for the year ended December 31, 2017. Cost of sales increased for the year ended December 31, 2018 primarily due to the Merger partially offset by cost synergies and currency impacts.

Cost of sales as a percentage of net sales for the year ended December 31, 2018 was 68 percent compared with 82 percent for the year ended December 31, 2017.

Cost of sales for the years ended December 31, 2018 and December 31, 2017 was negatively impacted by a $77 million and $1,355 million charge, respectively, related to amortization of the fair value step-up in Historical EID's inventories as a result of the Merger and the acquisition of FMC Corporation's Health and Nutrition business in November 2017.

Research and Development Expense ("R&D")

R&D expense was $955 million for the year ended December 31, 2019 and $1,070 million for the year ended December 31, 2018. The decrease for the year ended December 31, 2019 was primarily due to lower R&D costs previously allocated to the materials science and agriculture businesses that did not meet the definition of expenses related to discontinued operations in accordance with ASC 205 and therefore remained as costs of continuing operations for periods prior to the Distributions. R&D as a percentage of net sales was 4 percent and 5 percent for the years ended December 31, 2019 and 2018, respectively.

38

R&D expense was $1,070 million and $657 million for the years ended December 31, 2018 and 2017, respectively. The change was primarily due to the Merger. R&D as a percentage of net sales was 5 percent and 6 percent for the years ended December 31, 2018 and 2017, respectively.

Selling, General and Administrative Expenses ("SG&A")

For the year ended December 31, 2019, SG&A expenses totaled $2,663 million, down from $3,028 million in the year ended December 31, 2018. SG&A as a percentage of net sales was 12 percent and 13 percent for the years ended December 31, 2019 and 2018, respectively.

The decrease for the year ended December 31, 2019 as compared with the prior year was primarily due to lower SG&A costs previously allocated to the materials science and agriculture businesses that did not meet the definition of expenses related to discontinued operations in accordance with ASC 205 and therefore remained as costs of continuing operations for periods prior to the Distributions. In addition, SG&A decreased due to cost synergies.

SG&A expense was $3,028 million and $1,615 million for the years ended December 31, 2018 and 2017, respectively. The change was primarily due to the Merger. SG&A as a percentage of net sales was 13 percent and 14 percent for the years ended December 31, 2018 and 2017, respectively.

Amortization of Intangibles

Amortization of intangibles was $1,050 million for the year ended December 31, 2019, $1,044 million for the year ended December 31, 2018 and $505 million for the year ended December 31, 2017. Amortization in 2019 compared with 2018 was relatively flat. The increase in amortization in 2018 compared with 2017 was primarily due to the Merger. See Notes 3 and 14 to the Consolidated Financial Statements for additional information on intangible assets.

Restructuring and Asset Related Charges - Net

Restructuring and asset related charges - net were $314 million, $147 million, and $288 million for the years ended December 31, 2019, 2018 and 2017, respectively.

The activity for the year ended December 31, 2019 includes $138 million of charges related to the 2019 Restructuring Program, $113 million of charges related to the Synergy Program and a $63 million asset impairment charge related to an equity method investment. The charges for the year ended December 31, 2018 related to the Synergy Program. The charges for the year ended December 31, 2017 were comprised of $217 million related to the Synergy Program and $71 million related to other asset related impairments.

See Note 6 to the Consolidated Financial Statements for additional information.

Goodwill Impairment Charges

Goodwill impairments charges were $1,175 million during the year ended December 31, 2019. The goodwill impairment charges relate to the Nutrition & Biosciences and Non-Core segments. There were no goodwill related impairments in the years ended December 31, 2018 or 2017. See Note 14 to the Consolidated Financial Statements for additional information.

Integration and Separation Costs

Integration and separation costs, primarily reflecting costs related to the Merger, post-Merger integration, the Distributions, and beginning in the fourth quarter of 2019, the intended separation of the Nutrition & Biosciences business, were $1,342 million in 2019, $1,887 million in 2018 and $1,007 million in 2017.

Equity in Earnings of Nonconsolidated Affiliates

The Company's share of the earnings of nonconsolidated affiliates was $84 million, $447 million, and $367 million for the years ended December 31, 2019, 2018 and 2017, respectively. The decrease in 2019 was primarily due to lower equity earnings from the HSC Group which was mainly attributable to asset impairment charges partially offset by benefits associated with customer contract settlements. The increase in earnings of nonconsolidated affiliates for the year ended December 31, 2018 compared to the year ended December 31, 2017 is primarily due to the Merger. The year ended December 31, 2018 represents a full year of equity affiliate earnings for the Historical EID affiliates, compared to four months for the year ended December 31, 2017.

Sundry Income (Expense) - Net

Sundry income (expense) - net includes a variety of income and expense items such as foreign currency exchange gains or losses, interest income, dividends from investments, gains and losses on sales of investments and assets, non-operating pension and other post employment benefit plan credits or costs, and certain litigation matters. Sundry income (expense) - net for the year ended December 31, 2019 was $153 million compared with $92 million and $66 million in the years ended December 31, 2018 and 2017, respectively.

The year ended December 31, 2019 included a net gain on sale of assets and investments of $157 million, income related to non-operating pension and other post employment benefit plans of $74 million, and interest income of $55 million partially offset by foreign currency exchange losses of $110 million and miscellaneous expenses of $23 million which includes a $48 million charge reflecting a reduction in gross proceeds from lower withholding taxes related to a prior year legal settlement. The net gain on sale of assets includes income of $92 million related to a sale of assets within the Electronics & Imaging segment and as well as a gain of $28 million related to the sale of the Sustainable Solutions business unit within the Non-Core segment.

The year ended December 31, 2018 included income related to non-operating pension and other post employment benefit plans of $96 million, miscellaneous income of $83 million and interest income of $39 million, partially offset by foreign currency exchange losses of $93 million and loss on divestiture and change in joint venture ownership of $41 million. The foreign currency exchange losses included a $50 million foreign currency exchange loss related to adjustments to foreign currency exchange contracts as a result of U.S. tax reform. The loss on divestitures and change in joint venture ownership include a $14 million loss on the divestiture of the European XPS STYROFOAM^TM business (related to Safety & Construction) and a $27 million negative impact for adjustments related to the Dow Silicones ownership restructure (related to Non-Core).

The year ended December 31, 2017 include a net gain on sale of assets and investments of $65 million and income related to non-operating pension and other post employment benefit plans of $35 million, partially offset by foreign currency exchange losses of $54 million.

See Notes 7 and 20 to the Consolidated Financial Statements for additional information.

Interest Expense

Interest expense was $668 million and $55 million for the years ended December 31, 2019 and 2018, respectively. There was no interest expense related to continuing operations for year ended December 31, 2017 and less than one quarter of interest expense for the year ended December 31, 2018 as the Company did not have outstanding borrowings until the 2018 Senior Notes issuance in the fourth quarter of 2018. Refer to Note 15 to the Consolidated Financial Statements for additional information.

Provision for Income Taxes on Continuing Operations

The Company's effective tax rate fluctuates based on, among other factors, where income is earned and the level of income relative to tax attributes. For the year ended December 31, 2019, the Company's effective tax rate was (29.5) percent on a pre-tax loss from continuing operations of $474 million. The negative tax rate for the year ended December 31, 2019, was principally the result of the non-tax-deductible goodwill impairment charges impacting the Nutrition & Biosciences and Non-Core segments. See Note 14 for more information regarding the goodwill impairment charges. The underlying factors affecting the Company’s overall tax rate are summarized in Note 8 to the Consolidated Financial Statements.

For the year ended December 31, 2018, the Company's effective tax rate was 32.6 percent on pre-tax income from continuing operations of $600 million. The effective tax was favorably impacted by the geographic mix of earnings but was more than offset by a $67 million charge associated with a valuation allowance recorded against the net deferred tax asset position of the Company’s legal entity in Brazil related to the separated agriculture business.

For the year ended December 31, 2017, the Company's effective tax rate was 115.3 percent on a pre-tax loss from continuing operations of $1,525 million. The tax rate for 2017 was primarily impacted by the impact of the enactment of the Tax Cuts and Jobs Act (“Act”). The Act resulted in a one-time transition tax and required the Company to remeasure its U.S. federal deferred tax assets and liabilities. See Note 8 to the Consolidated Financial Statements for more information regarding the impact of the Act on the Company.

Income from Discontinued Operations, Net of Tax

Income from discontinued operations, net of tax was $1,214 million, $3,595 million and $1,058 million for the years ended December 31, 2019, 2018 and 2017, respectively. The decrease in 2019 is attributable to the timing of the Distributions. The increase from 2017 to 2018 is attributable to the timing of the Merger.

Refer to Note 4 to the Consolidated Financial Statements for additional information.

40

Net Income Attributable to Noncontrolling Interests

Net income attributable to noncontrolling interests, including the portion attributable to discontinued operations, was $102 million, $155 million, and $132 million, for the years ended December 31, 2019, 2018, and 2017 respectively.

Net income attributable to noncontrolling interests of continuing operations was $30 million, $39 million, and $16 million, for the years ended December 31, 2019, 2018, and 2017 respectively.

SUPPLEMENTAL UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

The following supplemental unaudited pro forma financial information (the “unaudited pro forma financial statements”) was derived from DuPont’s Consolidated Financial Statements, adjusted to give effect to certain events directly attributable to the Merger and the Distributions. In contemplation of the Distributions and to achieve the respective credit profiles of each of the current companies, in the fourth quarter of 2018, DowDuPont borrowed $12.7 billion under the 2018 Senior Notes and entered the Term Loan Facilities with an aggregate principal amount of $3.0 billion. Additionally, DuPont issued approximately $1.4 billion in commercial paper in May 2019 in anticipation of the Corteva Distribution (the “Funding CP Issuance” together with the 2018 Senior Notes and the Term Loan Facilities, the "Financings"). The unaudited pro forma financial statements below were prepared in accordance with Article 11 of Regulation S-X. The historical consolidated financial information has been adjusted to give effect to pro forma events that are (1) directly attributable to the Merger, the Distributions and the Financings (collectively the "Transactions"), (2) factually supportable and (3) with respect to the statements of operations, expected to have a continuing impact on the results. The unaudited pro forma statements of operations for the years ended December 31, 2019, 2018 and 2017 give effect to the pro forma events as if the Transactions had occurred on January 1, 2017.

Restructuring or integration activities or other costs following the Distributions that may be incurred to achieve cost or growth synergies of DuPont are not reflected. The unaudited pro forma statements of operations provides shareholders with summary financial information and historical data that is on a basis consistent with how DuPont reports current financial information.

The unaudited pro forma financial statements are presented for informational purposes only, and do not purport to represent what DuPont's results of operations or financial position would have been had the Transactions occurred on the dates indicated, nor do they purport to project the results of operations or financial position for any future period or as of any future date.

SEGMENT RESULTS

The Company's measure of profit/loss for segment reporting purposes is pro forma Operating EBITDA as this is the manner in which the Company's chief operating decision maker ("CODM") assessed performance and allocates resources. The Company defines pro forma Operating EBITDA as pro forma earnings (i.e. pro forma "Income (loss) from continuing operations before income taxes") before interest, depreciation, amortization, non-operating pension / other post employment benefits (“OPEB”) / charges, and foreign exchange gains/losses, excluding the impact of costs historically allocated to the materials science and agriculture businesses that did not meet the criteria to be recorded as discontinued operations and adjusted for significant items.

Pro forma adjustments were determined in accordance with Article 11 of Regulation S-X. Pro forma financial information is based on the Consolidated Financial Statements of DuPont, adjusted to give effect to the impact of certain items directly attributable to the Merger, the Distributions, and the Term Loan Facilities, the 2018 Senior Notes and the Funding CP Issuance (together, the "Financings"), including the use of proceeds from such Financings (collectively the "Transactions"). The historical consolidated financial information has been adjusted to give effect to pro forma events that are (1) directly attributable to the Transactions, (2) factually supportable and (3) with respect to the statements of operations, expected to have a continuing impact on the results. Events that are not expected to have a continuing impact on the combined results are excluded from the pro forma adjustments. Those pro forma adjustments include the impact of various supply agreements entered into in connection with the Dow Distribution ("supply agreements") and are adjustments to "Cost of sales." The impact of these supply agreements are reflected in pro forma Operating EBITDA for the periods noted above as they are included in the measure of profit/loss reviewed by the CODM in order to show meaningful comparability among periods while assessing performance and making resource allocation decisions. Refer to the Supplemental Unaudited Pro Forma Combined Financial Information section for further information.

2019 Versus 2018

Electronics & Imaging net sales were $3,554 million for the year ended December 31, 2019, down from $3,635 million for the year ended December 31, 2018 due to a 1 percent volume decline and a 1 percent unfavorable currency impact, primarily in Asia Pacific and EMEA. Volume decreased overall as Semiconductor Technologies and Interconnect Solutions declines more than offset volume gains in Image Solutions. Within Semiconductor Technologies, weakened demand in the memory sector was partially offset by increased volumes related to semiconductor packaging materials. Demand for advanced materials for smartphones remained strong but overall volumes in Interconnect Solutions were down due to soft circuit board demand. Volume growth in Image Solutions reflects increased demand for organic light emitting diode ("OLED") materials partially offset by volume declines in flexographic printing.

Pro forma operating EBITDA was $1,147 million for the year ended December 31, 2019, down 5 percent compared with $1,210 million for the year ended December 31, 2018, as higher raw material costs, volume declines and an unfavorable currency impact more than offset cost synergies and income associated with an asset sale.

2018 Versus 2017

Electronics & Imaging net sales were $3,635 million for the year ended December 31, 2018, up from pro forma net sales of $3,592 million for the year ended December 31, 2017. Net sales increased due to a 4 percent volume increase and a 1 percent favorable currency impact, partially offset by a 3 percent portfolio decrease, primarily related to the prior year divestiture of the SKC Haas Display Films business, and a 1 percent decrease in local price. Volume growth in the segment was driven by gains in Semiconductor Technologies, Image Solutions and Interconnect Solutions, primarily in Asia Pacific.

Pro forma Operating EBITDA was $1,210 million for the year ended December 31, 2018, up 2 percent compared with $1,190 million for the year ended December 31, 2017 as cost synergies and volume growth more than offset higher raw material costs.

Electronics & Imaging Outlook for 2020

Electronics & Imaging's 2020 sales are expected to benefit from stronger volumes partially offset by lower pricing gains. In addition, cost savings partially offset by the absence of gains associated with an asset sale are expected to favorably impact the segment.

2019 Versus 2018

Nutrition & Biosciences net sales were $6,076 million for the year ended December 31, 2019, down from $6,216 million for the year ended December 31, 2018, due to a 2 percent unfavorable currency impact, primarily in EMEA and Latin America, and a 1 percent decrease from portfolio actions partially offset by a 1 percent increase in local price. Volume was flat year over year as volume gains in Food & Beverage, primarily in cellulosics from growing demand in the meat alternatives and high protein nutritional beverages, was offset by declines in Health & Biosciences due to continued market-driven softness in biorefineries and decreased volume related to home and personal care applications which were partially offset by strength in food enzymes.

Pro forma operating EBITDA was $1,427 million for the year ended December 31, 2019, down 1 percent compared with $1,445 million for the year ended December 31, 2018 as unfavorable impacts related to product mix and currency were partially offset by cost synergies, productivity actions and pricing gains.

2018 Versus 2017

Nutrition & Biosciences net sales were $6,216 million for the year ended December 31, 2018, up from pro forma net sales of $5,389 million for the year ended December 31, 2017. The increase was due to a 11 percent increase from portfolio actions due to the acquisition of FMC’s Health & Nutrition business, a 3 percent increase in volume and a 1 percent increase in local price. Volume growth in the segment was led by gains in probiotics, specialty proteins, systems and texturants and pharmaceutical excipients, driven by demand in Asia Pacific. Demand for bioactives in home and personal care applications and animal nutrition also contributed to volume growth. Pricing gains were led by microbial control and systems and texturants.

Pro forma Operating EBITDA was $1,445 million for the year ended December 31, 2018, up 24 percent compared with $1,162 million for the year ended December 31, 2017, driven by favorable portfolio actions, cost synergies and volume growth, partially offset by higher costs due to growth investments.

Nutrition & Biosciences Outlook for 2020

Nutrition & Biosciences’ 2020 sales are expected to benefit from stronger volumes partially offset by decreases in local price. In addition, the segment is expected to benefit from productivity and cost savings.

2019 Versus 2018

Transportation & Industrial net sales were $4,950 million for the year ended December 31, 2019, down from $5,422 million for the year ended December 31, 2018. The change in net sales was due to a 10 percent decrease in volume and a 2 percent unfavorable currency impact, primarily in EMEA and Asia Pacific, which more than offset a 3 percent increase in local price. Volume declines were primarily due to destocking in the automotive channel and decreased demand in automotive and electronics markets in Asia Pacific and EMEA. Local price increased across all regions and primarily in Mobility Solutions.

Pro forma operating EBITDA was $1,313 million for the year ended December 31, 2019, down 14 percent compared with $1,518 million for the year ended December 31, 2018 as volume declines, higher raw material costs and an unfavorable currency impact were partially offset by pricing gains and cost synergies.

2018 Versus 2017

Transportation & Industrial net sales were $5,422 million for the year ended December 31, 2018, up from pro forma net sales of $4,958 million for the year ended December 31, 2017 due to a 6 percent increase in local price, 2 percent volume growth and a 1 percent benefit from currency, driven by EMEA. The increase in local price, primarily in Mobility Solutions, was driven by tight polymer supply and higher feedstock costs. Volume growth in the segment was primarily due to Healthcare & Specialty, led by growth in KALREZ® and VESPEL® high-performance parts in the electronics and aerospace markets, Industrial & Consumer, due to growth in DELRIN® and HYTREL® in the automotive market, and in Mobility Solutions due to growth in ZYTEL®. Broad based volume growth was led by U.S & Canada and Asia Pacific.

Pro forma Operating EBITDA was $1,518 million for the year ended December 31, 2018, up 23 percent compared with $1,235 million for the year ended December 31, 2017 due to price and volume gains, cost synergies and favorable currency impacts, partially offset by higher raw material costs.

Transportation & Industrial Outlook for 2020

Transportation & Industrial's 2020 sales are expected to decline as decreases in local price, primarily related to nylon, are anticipated to more than offset stronger volumes. The segment is expected to benefit from cost savings.

2019 Versus 2018

Safety & Construction net sales were $5,201 million for the year ended December 31, 2019, down from $5,294 million for the year ended December 31, 2018 as portfolio declines of 4 percent and a 1 percent unfavorable impact from currency in all regions more than offset a 3 percent increase in local price. The portfolio impact reflects the prior year divestiture of the European XPS STYROFOAM™ business on December 1, 2018. Local price increased across all businesses and in all regions.

Volume was flat compared with the prior year as volume growth in Water Solutions was offset by declines in Safety Solutions and Shelter Solutions. Water Solutions volume gains were driven by strong demand for ion exchange and reverse osmosis membranes mainly in the industrial market. Safety Solutions volume declined as a result of supply constraints and planned maintenance downtime which more than offset TYVEK® volume gains from increased demand in the personal protection market. Volume declines in Shelter Solutions were primarily due to weakness in the construction market.

Pro forma operating EBITDA was $1,419 million for the year ended December 31, 2019, up 11 percent compared with $1,283 million for the year ended December 31, 2018 due to local price gains, cost synergies, productivity improvements and volume gains partially offset by an unfavorable impact from currency.

2018 Versus 2017

Safety & Construction net sales were $5,294 million for the year ended December 31, 2018, up from pro forma net sales of $5,003 million for the year ended December 31, 2017 due to 3 percent volume growth, a 2 percent increase in local price and a 1 percent benefit from currency.

Volume growth in the segment was driven by broad based demand in industrial applications, with strength across all lines of business, particularly in Safety Solutions, as well as gains in Shelter Solutions and Water Solutions. The increase in local price was due to price gains across most businesses.

Pro forma Operating EBITDA was $1,283 million for the year ended December 31, 2018, up 9 percent compared with $1,178 million for the year ended December 31, 2017, due to cost synergies, volume and price gains and a favorable impact of currency, partially offset by the absence of prior year one-time gains and higher raw material and freight costs.

Safety & Construction Outlook for 2020

Safety & Construction's 2020 sales are expected to benefit primarily from increased volumes and favorable impacts related to the acquisitions in Water Solutions. Cost savings and higher local price partially offset by manufacturing headwinds in the first quarter of 2020 are expected to benefit the segment.

2019 Versus 2018

Non-Core net sales were $1,731 million for the year ended December 31, 2019, down from $2,027 million for the year ended December 31, 2018 due to a 11 percent decrease in volume, a 3 percent portfolio decline and a 2 percent unfavorable impact from currency, primarily in Asia Pacific, which more than offset a 1 percent increase in local price. Portfolio declines were due to the sale of the Sustainable Solutions business in the third quarter of 2019. Volume declines in Photovoltaic & Advanced Materials were driven by weak demand for trichlorosilanes due to low polysilicon production and lower paste sales in electronic component end markets. Biomaterials volume declines were primarily a result of a slow-down in demand in the carpet and apparel markets.

Pro forma operating EBITDA was $491 million for the year ended December 31, 2019, down 27 percent compared with $677 million for the year ended December 31, 2018 as a result of volume declines, lower HSC Group equity earnings due to lower customer settlements, and unfavorable impacts from currency and portfolio actions, which were partially offset by cost synergies and a gain on the sale of the Sustainable Solutions business.

2018 Versus 2017

Non-Core net sales were $2,027 million for the year ended December 31, 2018, down from pro forma net sales of $2,058 million for the year ended December 31, 2017. Net sales declined due to a 3 percent decrease in volume partially offset by a 1 percent increase in local price. Volume declines were primarily due to a decline in Photovoltaic & Advanced Materials demand related to metallization pastes and TEDLAR® backsheet materials, which were partially offset by volume increases in Clean Tech as a result of higher catalyst, alkylation, brinks and acid equipment sales.

Pro forma Operating EBITDA was $677 million for the year ended December 31, 2018, up 2 percent compared with $661 million for the year ended December 31, 2017 as volume declines and higher raw material and production costs were partially offset by higher HSC Group equity earnings due to higher customer settlements.

50

Non-Core Outlook for 2020

Non-Core's 2020 sales are expected to be down due to an unfavorable impact from portfolio declines due to the sale of the Sustainable Solutions business in the third quarter of 2019 and anticipated declines in volume and local price. The segment is also expected to be unfavorably impacted by lower HSC Group equity earnings due to lower customer settlements and the absence of a gain from the sale of the Sustainable Solutions business, partially offset by cost savings.

Liquidity & Capital Resources

The Company continually reviews its sources of liquidity and debt portfolio and occasionally may make adjustments to one or both to ensure adequate liquidity. The Company’s primary source of incremental liquidity is cash flows from operating activities. Management expects the generation of cash from operations and the ability to access the debt capital markets and other sources of liquidity will continue to provide sufficient liquidity and financial flexibility to meet the Company’s and its subsidiaries obligations as they come due.

In November 2018, DuPont consummated the offering of the senior unsecured notes (the "2018 Senior Notes") in an aggregate principal amount of $12.7 billion. The offering consisted of $0.5 billion in floating rate notes due November 2020, $0.3 billion in floating rate notes due November 2023, and six tranches of fixed-rate notes: $1.5 billion due November 2020, $2.5 billion due November 2023, $1.85 billion due November 2025, $2.25 billion due November 2028, $1.65 billion due November 2038 and $2.15 billion due November 2048. The net proceeds of the offering after the underwriting discount was $12.6 billion. See Note 15 to the Consolidated Financial Statements for additional information on the interest related to the 2018 Senior Notes.

Pending receipt of the proceeds from the Special Cash Payment, the Company expects to refinance the November 2020 maturities for the interim period.

Term Loan and Revolving Credit Facilities

In November 2018, the Company entered into a term loan agreement that establishes two term loan facilities in the aggregate principal amount of $3 billion, (the “Term Loan Facilities”) as well as a five-year $3 billion revolving credit facility (the “Five-Year Revolving Credit Facility”). Effective May 2, 2019, the Company fully drew the two Term Loan Facilities in the aggregate principal amount of $3.0 billion and the Five-Year Revolving Credit Facility became effective and available. In June 2019, the Company entered into a 364-day $750 million revolving credit facility (the “364-Day Revolving Credit Facility”). The Five-Year Revolving Credit Facility is generally expected to remain undrawn, and serve as a backstop to the Company’s commercial paper and letter of credit issuance. The 364-Day Revolving Credit Facility may be drawn against for general corporate purposes, including but not limited to net working capital, costs and expenses. The Company intends to renew the 364-Day Revolving Credit Facility on or prior to expiration.

Commercial Paper

In April 2019, DuPont authorized a $3 billion commercial paper program (the “DuPont Commercial Paper Program”). As of December 31, 2019, the Company issued $1.8 billion of commercial paper. The Company’s issuance under the Commercial Paper Program included the issuance of $1.4 billion (the “Funding CP Issuance”) in May 2019 in anticipation of the Corteva Distribution, as well as borrowings for general corporate purposes.

The net proceeds from the 2018 Senior Notes, Term Loan Facilities, and commercial paper together with cash from operations were used to fund cash contributions to Dow and Corteva, and DowDuPont’s November 2018 $3.0 billion share repurchase program, which was completed in the first quarter of 2019. The remaining proceeds were used to reduce outstanding liabilities of Historical EID that would otherwise be attributed to Corteva; and further pay any related premiums, fees and expenses.

Nutrition & Biosciences Financing    

In connection with the Proposed N&B Transaction, N&B Inc. entered into a Bridge Commitment Letter in an aggregate principal amount of $7.5 billion, (the “Bridge Loans”) to secure committed financing for the Special Cash Payment and related financing fees and expenses. The aggregate commitment under the Bridge Letter is reduced by, among other things, (1) the amount of net cash proceeds received by N&B Inc. from any issuance of senior unsecured notes pursuant to a Rule 144A offering or other private placement, (the "N&B Notes Offering") and (2) certain qualifying term loan commitments under senior unsecured term loan facilities.

51

In January 2020, N&B Inc. entered into a senior unsecured term loan agreement in the amount of $1.25 billion split evenly between three- and five-year facilities. As a result of entry into the term loan agreement, the commitments under the Bridge Commitment Letter were reduced to $6.25 billion. The remaining $6.25 billion is expected to be funded through the N&B Notes Offering and/or the Bridge Loans. The proceeds from drawdowns on the term loan facilities and the N&B Notes Offering, if any, and/or the Bridge Loans would be used to make the Special Cash Payment and to pay the related financing fees and expenses. The commitments under the Bridge Commitment Letter and the availability of funding under the term loan agreement are subject to customary closing conditions including among others, the satisfaction of substantially all the conditions to the consummation of the proposed transaction with IFF.

Borrowing under the term loan agreement and, if any, under the Bridge Loans would occur immediately prior to the closing of the Proposed N&B Transaction. Any issuance of the N&B Note Offering for some or all the remaining $6.25 billion would likely occur in advance of the closing.

Pursuant to the Merger Agreement, the fees and expenses associated with the financing, including fees associated with any prepayment will be borne A) entirely by N&B Inc. if the transaction closes; and (B) equally by DuPont and IFF if the Merger Agreement terminates. However, if the Merger Agreement is terminated by IFF, in accordance with its terms, for breach by DuPont, such fees and expenses will be borne entirely by DuPont; and if terminated by DuPont in accordance with its terms for breach by IFF, such fees and expenses will be borne entirely by IFF.

Credit Ratings

The Company's credit ratings impact its access to the debt capital markets and cost of capital. The Company remains committed to maintaining a strong financial position with a balanced financial policy focused on maintaining a strong investment-grade rating and driving shareholder value and remuneration. At January 31, 2020, DuPont's credit ratings were as follows:

Credit Ratings	Long-Term Rating	Short-Term Rating	Outlook
Standard & Poor’s	A-	A-2	Negative Watch
Moody’s Investors Service	Baa1	P-2	Stable
Fitch Ratings	BBB+	F-2	Stable

The Company's indenture covenants include customary limitations on liens, sale and leaseback transactions, and mergers and consolidations, subject to certain limitations. The 2018 Senior Notes also contain customary default provisions. The Term Loan Facilities, the Five-Year Revolving Credit Facility and the 364-Day Revolving Credit Facility contain a financial covenant, typical for companies with similar credit ratings, requiring that the ratio of Total Indebtedness to Total Capitalization for the Company and its consolidated subsidiaries not exceed 0.60. At December 31, 2019, the Company was in compliance with this financial covenant.

The Company's cash, cash equivalents and marketable securities at December 31, 2019 and December 31, 2018 were $1.5 billion and $8.6 billion, respectively, of which $1.4 billion at December 31, 2019 and $2.1 billion at December 31, 2018 were held by subsidiaries in foreign countries, including United States territories. The decrease in cash and cash equivalents held by subsidiaries in foreign countries is due to repatriation activities. For each of its foreign subsidiaries, the Company makes an assertion regarding the amount of earnings intended for permanent reinvestment, with the balance available to be repatriated to the United States.

Summary of Cash Flows

The Company’s cash flows from operating, investing and financing activities, as reflected in the Consolidated Statements of Cash Flows, are summarized in the following table. The cash flows related to Dow and Corteva have not been segregated and are included in the Consolidated Statements of Cash Flows for all periods presented, as applicable.

Cash Flows from Operating Activities

Cash provided by operating activities was $1,409 million and $4,731 million for the years ended December 31, 2019 and 2018, respectively. Cash provided by operating activities decreased in 2019 compared with 2018, primarily due to the impact of the Dow and Corteva Distributions to period earnings, partially offset by a decrease in the use of cash for net working capital versus the prior period. Cash used for operating activities for the year ended December 31, 2017 was $765 million. Cash provided by operating activities increased in 2018 compared to 2017, primarily driven by a decrease in cash used for working capital requirements and higher cash earnings, which were partially offset by increased pension contributions, higher integration and separation costs, and the absence of certain cash receipts in 2017.

1. Net working capital has been restated to exclude the assets and liabilities related to the Distributions which are presented as assets and liabilities of discontinued operations, respectively, in the Consolidated Balance Sheets for all periods presented.

Cash Flows from Investing Activities

Cash used for investing activities in 2019 was $2,313 million compared to cash used for investing of $2,462 million in 2018. The decrease in cash used was primarily attributable to lower capital expenditures, partially offset by a decrease in proceeds from sales and maturities of investments, net of purchases of investments, as well as a decline in proceeds from interests in trade accounts receivable conduits. Cash used for investing activities in 2018 was primarily for capital expenditures and purchases of investments, which were partially offset by proceeds from sales and maturities of investments and proceeds from interests in trade accounts receivable conduits. Cash provided by investing activities in 2017 was $14,325 million primarily from proceeds from interests in trade accounts receivable conduits, cash acquired in the Merger, proceeds from sales and maturities of investments and divestitures related primarily to businesses within Corteva and Dow. These items were partially offset by capital expenditures, purchases of investments and loans to nonconsolidated affiliates.

Cash Flows from Financing Activities

Cash used for financing activities in 2019 was $11,550 million compared with $1,918 million in 2018. The primary driver of the increased use of cash is the cash held by Dow and Corteva at the respective Distributions, reflecting cash on the balance sheet of each at the time of their respective spinoff; as well as payments of long-term debt of Historical Dow and Historical EID prior to the Distributions. These uses were partly offset by issuance of long-term debt in the form of the Term Loan Facilities draw in May 2019. Cash used for financing activities in 2018 included payments of notes payable and long-term debt, repurchases of DowDuPont common stock and dividends paid to stockholders. These items were largely offset by proceeds from the issuance of long-term debt. Cash used for financing activities was $6,554 million in 2017 and included dividends paid to stockholders, repurchases of DowDuPont common stock and payments of notes payable and long-term debt.

Dividends

The following table provides dividends paid to common shareholders for the years ended December 31, 2019, 2018, and 2017:

Dividends Paid	December 31, 2019		December 31, 2018		December 31, 2017

Dividends paid to common stockholders 2	$	1,611	$	3,491	$	3,394

1. The 2017 dividend is comprised of $0.38 per share of DowDuPont dividends declared and paid in the fourth quarter of 2017 and the remaining amount relates to payments of Historical Dow dividends declared prior to the Merger.

2. The 2017 dividend consists of $885 million paid to DowDuPont common stockholders for dividends declared after the Merger, as well as $2,179 million paid to Historical Dow common stockholders for dividends declared prior to the Merger, and $330 million paid to Historical EID common stockholders after the Merger for dividends declared prior to the Merger.

On February 12, 2020, the DuPont Board of Directors declared a first quarter dividend of $0.30 per share payable on March 16, 2020, to shareholders of record on February 28, 2020.

53

Share Buyback Programs

On June 1, 2019, the Company's Board of Directors authorized a new $2 billion share buyback program, which expires on June 1, 2021. At December 31, 2019, the Company had repurchased 10.8 million shares under this program at a total cost of $750 million.

See Part II, Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities and Note 18 to the Consolidated Financial Statements, for additional information.

Pension and Other Post Employment Plans

Historical Dow and Historical EID did not merge their pension plans and other post employment benefit plans as a result of the Merger. Historical Dow and Historical EID had defined benefit pension plans in the United States and a number of other countries. Subsequent to the Distributions, the Company retained defined benefit pension plans in a number of other countries but does not have any qualified defined benefit pension plan in the United States.

The Company's funding policy is to contribute to defined benefit pension plans based on pension funding laws and local country requirements. Contributions exceeding funding requirements may be made at the Company's discretion. The Company expects to contribute approximately $85 million to its pension plans in 2020. The amount and timing of the Company’s actual future contributions will depend on applicable funding requirements, discount rates, investment performance, plan design, and various other factors, separations and distributions. See Note 20 to the Consolidated Financial Statements for additional information concerning the Company’s pension plans.

Historical Dow's funding policy was to contribute to plans when pension laws and/or economics either require or encourage funding. Prior to the Dow Distribution, Historical Dow made discretionary contributions exceeding funding requirements. In 2018 and 2017, Historical Dow contributed $1,656 million and $1,676 million to its pension plans, respectively, including contributions to fund benefit payments for its non-qualified pension plans. In the third quarter of 2018, Historical Dow made $1,100 million discretionary contributions to their principal U.S. pension plans, which are included in the 2018 contribution amounts above. The discretionary contributions were based on Historical Dow's funding policies, which permit discretionary contributions to defined benefit pension plans when economics encourage funding, and reflected considerations relating to tax deductibility and capital structure. During the three months of 2019, Historical Dow made contributions of $103 million to Historical Dow plans that were separated with Dow after the Distributions.

Historical EID's funding policy was to contribute to defined benefit pension plans based on pension funding laws and local country requirements. Prior to the Corteva Distribution, Historical EID made discretionary contributions exceeding funding requirements. Historical EID contributed $1,308 million, including discretionary contributions of $1,100 million to its principal U.S. pension plans, in 2018 and $68 million post-Merger in 2017 to its pension plans. These contributions included contributions to fund benefit payments for non-qualified pension plans. The discretionary contributions were based on Historical EID's funding policies, which permit discretionary contributions to defined benefit pension plans when economics encourage funding, and reflected considerations relating to tax deductibility and capital structure. During the five months of 2019, Historical EID made $36 million contributions to plans that were separated from the Company in conjunction with the Corteva Distribution.

Restructuring

In June 2019, DuPont approved restructuring actions to simplify and optimize certain organizational structures following the completion of the Distributions (the "2019 Restructuring Program"). As a result of these actions, the Company has recorded pre-tax restructuring charges of $138 million inception-to-date, consisting of severance and related benefit costs of $104 million, and asset related charges of $34 million. The Company expects actions related to this program to be substantially complete by the second half of 2020. Future cash payments related to the 2019 Restructuring Program are anticipated to $86 million and relate to the payment of severance and related benefits.

In September and November 2017, the Company approved post-merger restructuring actions under the DowDuPont Cost Synergy Program, adopted by the DowDuPont Board of Directors. The Synergy Program was designed to integrate and optimize the organization following the Merger and in preparation for the Distributions whereby the Company has recorded pre-tax restructuring charges attributable to the continuing operations of DuPont of $485 million inception-to-date, consisting of severance and related benefit costs of $215 million, asset related charges of $209 million and contract termination charges of $61 million. The activities related to the Synergy Program are expected to result in additional cash expenditures of $76 million and relate primarily to the payment of severance and related benefit costs. Actions associated with the Synergy Program, including employee separations, are considered substantially complete (see Note 6 to the Consolidated Financial Statements).

54

Off-balance Sheet Arrangements

Guarantees arise in the ordinary course of business from relationships with customers and nonconsolidated affiliates when the Company undertakes an obligation to guarantee the performance of others if specific triggering events occur. At December 31, 2019 and December 31, 2018, the Company had directly guaranteed $187 million and $199 million, respectively, of such obligations.

The Company anticipates a macro environment similar to 2019 with modest demand improvement in select areas, most notably for next generation smart phones, probiotics, and in semiconductor markets, to be offset by challenging nylon market dynamics and continued weakness in automotive markets. In addition, the Company expects productivity improvements and cost actions to be more than offset by increased amortization of intangible assets and integration and separation costs related to the intended separation of the N&B Business. The Company continues to closely monitor macroeconomic and geopolitical developments. 

Recent Accounting Pronouncements

See Note 2 to the Consolidated Financial Statements for a description of recent accounting pronouncements.

Critical Accounting Estimates

The Company's significant accounting policies are more fully described in Note 1 to the Consolidated Financial Statements. Management believes that the application of these policies on a consistent basis enables the Company to provide the users of the financial statements with useful and reliable information about the Company's operating results and financial condition.

The preparation of the Consolidated Financial Statements in conformity with generally accepted accounting principles ("GAAP") in the United States of America requires management to make estimates and assumptions that affect the reported amounts, including, but not limited to, receivable and inventory valuations, impairment of tangible and intangible assets, long-term employee benefit obligations, income taxes, restructuring liabilities, environmental matters and litigation. Management's estimates are based on historical experience, facts and circumstances available at the time and various other assumptions that are believed to be reasonable. The Company reviews these matters and reflects changes in estimates as appropriate. Management believes that the following represent some of the more critical judgment areas in the application of the Company's accounting policies which could have a material effect on the Company's financial position, liquidity or results of operations.

Pension Plans

Accounting for employee benefit plans involves numerous assumptions and estimates. Discount rate and expected return on plan assets are two critical assumptions in measuring the cost and benefit obligation of the Company's pension plans. Management reviews these two key assumptions when plans are re-measured. These and other assumptions are updated periodically to reflect the actual experience and expectations on a plan specific basis as appropriate. As permitted by GAAP, actual results that differ from the assumptions are accumulated on a plan by plan basis and to the extent that such differences exceed 10 percent of the greater of the plan's benefit obligation or the applicable plan assets, the excess is amortized over the average remaining service period of active employees or the average remaining life expectancy of the inactive participants if all or almost all of a plan’s participants are inactive.

For the majority of the benefit plans, the Company utilizes the Aon AA corporate bond yield curves to determine the discount rate, applicable to each country, at the measurement date.

The Company establishes strategic asset allocation percentage targets and appropriate benchmarks for significant asset classes in accordance with the laws and practices of those countries. Where appropriate, asset-liability studies are also taken into consideration. For plans, the long-term expected return on plan assets pension expense is determined using the fair value of assets.

55

The following table highlights the potential impact on the Company's pre-tax earnings due to changes in certain key assumptions with respect to the Company's pension plans based on assets and liabilities at December 31, 2019:

Pre-tax Earnings Benefit (Charge) (Dollars in millions)	1/4 Percentage Point Increase		1/4 Percentage Point Decrease
Discount rate	$	1	$	1
Expected rate of return on plan assets	9		(9		)

Additional information with respect to pension plans, liabilities and assumptions is discussed under "Long-term Employee Benefits" beginning on page 59 and in Note 20 to the Consolidated Financial Statements.

Legal Contingencies

The Company's results of operations could be affected by significant litigation adverse to the Company, including product liability claims, patent infringement and antitrust claims, and claims for third party property damage or personal injury stemming from alleged environmental torts. The Company records accruals for legal matters when the information available indicates that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Management makes adjustments to these accruals to reflect the impact and status of negotiations, settlements, rulings, advice of counsel and other information and events that may pertain to a particular matter. Predicting the outcome of claims and lawsuits and estimating related costs and exposure involves substantial uncertainties that could cause actual costs to vary materially from estimates. In making determinations of likely outcomes of litigation matters, management considers many factors. These factors include, but are not limited to, the nature of specific claims including unasserted claims, the Company's experience with similar types of claims, the jurisdiction in which the matter is filed, input from outside legal counsel, the likelihood of resolving the matter through alternative dispute resolution mechanisms, and the matter's current status. Considerable judgment is required in determining whether to establish a litigation accrual when an adverse judgment is rendered against the Company in a court proceeding. In such situations, the Company will not recognize a loss if, based upon a thorough review of all relevant facts and information, management believes that it is probable that the pending judgment will be successfully overturned on appeal. A detailed discussion of significant litigation matters is contained in Note 16 to the Consolidated Financial Statements.

Income Taxes

The breadth of the Company's operations and the global complexity of tax regulations require assessments of uncertainties and judgments in estimating taxes the Company will ultimately pay. The final taxes paid are dependent upon many factors, including negotiations with taxing authorities in various jurisdictions, outcomes of tax litigation and resolution of disputes arising from federal, state and international tax audits in the normal course of business. The resolution of these uncertainties may result in adjustments to the Company's tax assets and tax liabilities. It is reasonably possible that changes to the Company’s global unrecognized tax benefits could be significant; however, due to the uncertainty regarding the timing of completion of audits and possible outcomes, a current estimate of the range of increases or decreases that may occur within the next twelve months cannot be made.

Deferred income taxes result from differences between the financial and tax basis of the Company's assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Significant judgment is required in evaluating the need for and magnitude of appropriate valuation allowances against deferred tax assets. The realization of these assets is dependent on generating future taxable income, as well as successful implementation of various tax planning strategies. For example, changes in facts and circumstances that alter the probability that the Company will realize deferred tax assets could result in recording a valuation allowance, thereby reducing the deferred tax asset and generating a deferred tax expense in the relevant period. In some situations, these changes could be material.

At December 31, 2019, the Company had a net deferred tax liability balance of $3.3 billion, net of a valuation allowance of $0.6 billion. Realization of deferred tax assets is expected to occur over an extended period of time. As a result, changes in tax laws, assumptions with respect to future taxable income, and tax planning strategies could result in adjustments to deferred tax assets. See Note 8 to the Consolidated Financial Statements for additional details related to the deferred tax liability balance.

Goodwill

The assets and liabilities of acquired businesses are measured at their estimated fair values at the dates of acquisition. The excess of the purchase price over the estimated fair value of the net assets acquired, including identified intangibles, is recorded as goodwill. The determination and allocation of fair value to the assets acquired and liabilities assumed is based on various assumptions and valuation methodologies requiring considerable management judgment, including estimates based on historical information, current market data and future expectations. The principal assumptions utilized in the Company's valuation

56

methodologies include the projected revenue, earnings before interest, depreciation and amortization (EBITDA) margins, the weighted average costs of capital, the terminal growth rates, and other market data. Although the estimates are deemed reasonable by management based on information available at the dates of acquisition, those estimates are inherently uncertain.

Assessment of the potential impairment of goodwill, other intangible assets, property, plant and equipment, investments in nonconsolidated affiliates, and other assets is an integral part of the Company's normal ongoing review of operations. Testing for potential impairment of these assets is significantly dependent on numerous assumptions and reflects management's best estimates at a particular point in time. The dynamic economic environments in which the Company's diversified product lines operate, and key economic and product line assumptions with respect to projected selling prices, market growth and inflation rates, can significantly affect the outcome of impairment tests. Estimates based on these assumptions may differ significantly from actual results. Changes in factors and assumptions used in assessing potential impairments can have a significant impact on the existence and magnitude of impairments, as well as the time in which such impairments are recognized. In addition, the Company continually reviews its diverse portfolio of assets to ensure they are achieving their greatest potential and are aligned with the Company's growth strategy. Strategic decisions involving a particular group of assets may trigger an assessment of the recoverability of the related assets. Such an assessment could result in impairment losses.

The Company performs goodwill impairment testing at the reporting unit level which is defined as the operating segment or one level below the operating segment. One level below the operating segment, or component, is a business in which discrete financial information is available and regularly reviewed by segment management. The Company aggregates certain components into reporting units based on economic similarities. Subsequent to the Distributions and as part of the Second Quarter Segment Realignment, the Company assessed and redefined certain reporting units effective June 1, 2019. The Company tests goodwill for impairment annually (during the fourth quarter), or more frequently when events or circumstances indicate it is more likely than not that the fair value of the reporting unit has declined below its carrying value. As of the date of the annual impairment test, the Company identified nine reporting units, of which seven have goodwill assigned.

For purposes of goodwill impairment testing, 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. Qualitative factors assessed at the Company level include, but are not limited to, GDP growth rates, long-term commodity prices, equity and credit market activity, discount rates, foreign exchange rates, and overall financial performance. Qualitative factors assessed at the reporting unit level include, but are not limited to, changes in industry and market structure, competitive environments, planned capacity and new product launches, cost factors such as raw material prices, and financial performance of the reporting unit. 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 performed, 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. The Company determined fair values for each of the reporting units using a combination of the income approach and 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 uses its internal forecasts to estimate future cash flows and includes an estimate of long-term future growth rates based on its most recent views of the long-term outlook for each reporting unit. The discounted cash flow valuations are completed using the following key assumptions: projected revenue growth rates; discount rates; tax rates; and terminal values. These key assumptions are determined through evaluation of the Company as a whole and underlying business fundamentals and industry risk. Actual results may differ from those assumed in the Company’s forecasts. The Company derives its discount rates using a capital asset pricing model and analyzing published rates for industries relevant to its reporting units to estimate the cost of equity financing. The Company uses discount rates that are commensurate with the risks and uncertainty inherent in the respective reporting units and in its internally developed forecasts. Discount rates used in the Company’s reporting unit valuations ranged from 7.25% to 9.75%.

Under the market approach, the Company used the Guideline Public Company Method ("GPCM"). The selected peer sets were based on close competitors and reviews of analysts' reports, public filings, and industry research related to firms operating in the respective reporting units industries. In selecting the EBIT/EBITDA multiples and determining the fair value, the Company considered the size, growth, and profitability of each reporting unit versus the relevant guideline public companies.

Estimating the fair value of reporting units requires the use of estimates and significant judgments that are based on a number of factors including actual operating results. It is reasonably possible that the judgments and estimates described above could change in future periods.

57

2019 Interim Goodwill Impairment Testing

During the second quarter of 2019, the Internal SP Distribution and the Second Quarter Segment Realignment served as triggering events requiring the Company to perform impairment analyses related to goodwill. This analysis resulted in an aggregate pre-tax, non-cash impairment charge of $1,175 million impacting the Nutrition & Biosciences and Non-Core segments.

The Company performed an interim impairment analysis for all reporting units using a discounted cash flow model (a form of the income approach), utilizing Level 3 unobservable inputs. The Company’s significant estimates in this analysis include, but are not limited to, future cash flow projections, the weighted average cost of capital, the terminal growth rate, and the tax rate. The Company believes the assumptions and estimates utilized are both reasonable and appropriate. The key assumption driving the change in fair value was the lower financial projections resulting from developing market conditions, events and circumstances that evolved throughout 2019. Future cash flow estimates are, by their nature, subjective and actual results may differ materially from the Company’s estimates. If the Company’s ongoing estimates of future cash flows are not met, the Company may have to record additional impairment charges in future periods. The Company’s estimates of future cash flows are based on current regulatory and economic climates, recent operating results, and planned business strategy. These estimates could be negatively affected by changes in federal, state, or local regulations or economic downturns. The impairment charges impacting the Non-Core segment were determined through utilization of the market approach which was considered most appropriate as the Company continues to evaluate strategic options for these businesses. The assumptions and estimates used in determining the fair values of the reporting units contain uncertainties, and any changes to these assumptions and estimates could have a negative impact and result in a future impairment. For further information see Note 14 to the Consolidated Financial Statements.

2019 Annual Goodwill Impairment Testing

In the fourth quarter of 2019, quantitative testing was performed on all of the Company’s reporting units that carry goodwill. Based on the results of the testing, the estimated fair value of each of the reporting units exceeded their carrying values. The dynamic economic environments in which the Company's diversified product lines operate, and key economic and product line assumptions with respect to projected selling prices, market growth and inflation rates, can significantly affect the outcome of impairment tests. Estimates based on these assumptions may differ significantly from actual results. Certain reporting units within the Non-Core segment have limited headroom and changes in factors, circumstances and assumptions used in assessing potential impairments can have a significant impact on the existence and magnitude of impairments, as well as the time in which such impairments are recognized.

Contractual Obligations

Information related to the Company's significant contractual obligations is summarized in the following table:

			Payments Due In
In millions	Total at December 31, 2019		2020		2021-2022		2023-2024		2025 and beyond
Long-term debt obligations 1,2	$	15,710	$	2,004	$	3,006	$	2,800	$	7,900
Expected cash requirements for interest 3	7,234		666		1,133		902		4,533
Finance lease obligations	4		1		2		—		1
Operating leases	615		148		221		100		146

Total contractual obligations	$	25,699	$	3,350	$	4,838	$	3,984	$	13,527

1. Included in the Consolidated Financial Statements.

2. Includes long-term debt due within one year, but excludes unamortized debt fees of $95 million.

3. Cash requirement for interest on long-term debt was calculated using current interest rates at December 31, 2019 and includes $255 million of various floating rate notes and debt instruments.

4. Represents enforceable and legally binding agreements in excess of $1 million to purchase goods or services that specify fixed or minimum quantities; fixed, minimum or variable price provisions; and the approximate timing of the agreement.

5. Includes liabilities related to environmental remediation, legal settlements, and other noncurrent liabilities. The table excludes uncertain tax positions due to uncertainties in the timing of the effective settlement of tax positions with the respective taxing authorities and deferred tax liabilities as it is impractical to determine whether there will be a cash impact related to these liabilities. The table also excludes deferred revenue as it does not represent future cash requirements arising from contractual payment obligations.

The Company expects to meet its contractual obligations through its normal sources of liquidity and believes it has the financial resources to satisfy the contractual obligations that arise in the ordinary course of business.

58

Long-term Employee Benefits

The Company has various obligations to its employees and retirees. The Company maintains retirement-related programs in many countries that have a long-term impact on the Company's earnings and cash flows. These plans are typically defined benefit pension plans. The Company has a few medical, dental and life insurance benefits for employees, pensioners and survivors and for employees (other post employment benefits or "OPEB" plans).

Pension coverage for employees of the Company's non-U.S. consolidated subsidiaries is provided, to the extent deemed appropriate, through separate plans. The Company regularly explores alternative solutions to meet its global pension obligations in the most cost effective manner possible as demographics, life expectancy and country-specific pension funding rules change. Where permitted by applicable law, the Company reserves the right to change, modify or discontinue its plans that provide pension, medical, dental and life insurance. Benefits under defined benefit pension plans are based primarily on years of service and employees' pay near retirement.

Pension benefits are paid primarily from trust funds established to comply with applicable laws and regulations of the sovereign country in which the pension plan operates. Unless required by law, the Company does not make contributions that are in excess of tax deductible limits. The actuarial assumptions and procedures utilized are reviewed periodically by the plans' actuaries to provide reasonable assurance that there will be adequate funds for the payment of benefits. Thus, there is not necessarily a direct correlation between pension funding and pension expense. In general, however, improvements in plans' funded status tends to moderate subsequent funding needs.

The Company contributed $487 million, $93 million, and $30 million to its funded pension plans for the years ended December 31, 2019, December 31, 2018, and December 31, 2017, respectively.

The Company does maintain one U.S. pension benefit plan. This plan is a separate unfunded plan and these benefits are paid to employees from operating cash flows. The Company's remaining pension plans with no plan assets are paid from operating cash flows. The Company made benefit payments of $71 million, $61 million, and $21 million to its unfunded plans for the years ended December 31, 2019, December 31, 2018, and December 31, 2017, respectively.

The Company's OPEB plans are unfunded and the cost is paid from operating cash flows. Pre-tax cash requirements to cover payments for the Company's OPEB plans was $1 million for the years ended December 31, 2019 and December 31, 2018. For the year ended December 31, 2017, the pre-tax cash requirement was immaterial.

In 2020, the Company expects to contribute approximately $85 million to its funded pension plans and its remaining plans with no plan assets, and about $1 million for its OPEB plans. The amount and timing of actual future contributions will depend on applicable funding requirements, discount rates, investment performance, plan design, and various other factors.

The Company's income can be significantly affected by pension and defined contribution charges/(benefits) as well as OPEB costs. The following table summarizes the extent to which the Company's income for the years ended December 31, 2019, December 31, 2018, and December 31, 2017 was affected by pre-tax charges related to long-term employee benefits:

	For the Years Ended
In millions	December 31, 2019		December 31, 2018		December 31, 2017
Long-term employee benefit plan charges (benefit)	$	98	$	75	$	98

The above charges (benefit) for pension and OPEB are determined as of the beginning of each period. See "Pension Plans and Other Post Employment Benefits" under the Critical Accounting Estimates section beginning on page 55 of this report for additional information on determining annual expense.

For 2020, long term employee benefit expense from continuing operations is expected to increase by about $35 million. The increase is mainly due to lower expected return on plan assets.

59

Environmental Matters

The Company operates global manufacturing, product handling and distribution facilities that are subject to a broad array of environmental laws and regulations. Such rules are subject to change by the implementing governmental agency, and the Company monitors these changes closely. Company policy requires that all operations fully meet or exceed legal and regulatory requirements. In addition, the Company implements voluntary programs to reduce air emissions, minimize the generation of hazardous waste, decrease the volume of water use and discharges, increase the efficiency of energy use and reduce the generation of persistent, bioaccumulative and toxic materials. Management has noted a global upward trend in the amount and complexity of proposed chemicals regulation. The costs to comply with complex environmental laws and regulations, as well as internal voluntary programs and goals, are significant and will continue to be significant for the foreseeable future.

Pre-tax environmental expenses charged to income from continuing operations are summarized below:

(Dollars in millions)	For the Year Ended December 31, 2019		For the Year Ended December 31, 2018		For the Year Ended December 31, 2017
Environmental operating costs	$	183	$	182	$	61
Environmental remediation costs	28		15		3
	$	211	$	197	$	64

Based on existing facts and circumstances, management does not believe that year-over-year changes, if any, in environmental expenses charged to current operations will have a material impact on the Company's financial position, liquidity or results of operations. Annual expenditures in the near term are not expected to vary significantly from the range of such expenditures experienced in the past few years. Longer term, expenditures are subject to considerable uncertainty and may fluctuate significantly.

Environmental Operating Costs

As a result of its operations, the Company incurs costs for pollution abatement activities including waste collection and disposal, installation and maintenance of air pollution controls and wastewater treatment, emissions testing and monitoring, and obtaining permits. The Company also incurs costs related to environmental related research and development activities including environmental field and treatment studies as well as toxicity and degradation testing to evaluate the environmental impact of products and raw materials.

Remediation Accrual

Changes in the remediation accrual balance are summarized below:

(Dollars in millions)
Balance at December 31, 2017	$	51
Remediation payments	(15		)
Net increase in remediation accrual	15
Balance at December 31, 2018	$	51
Remediation payments	(12		)
Net increase in remediation accrual	28
Net change, indemnification 1	10
Balance at December 31, 2019	$	77

1. Represents the net change in indemnified remediation obligations based on activity pursuant to the Separation and Distribution Agreement and Letter Agreement as discussed below and in Notes 4 and 16 to the Consolidated Financial Statements.

Considerable uncertainty exists with respect to environmental remediation costs, and, under adverse changes in circumstances, the potential liability may range up to $170 million above the amount accrued as of December 31, 2019. However, based on existing facts and circumstances, management does not believe that any loss, in excess of amounts accrued, related to remediation activities at any individual site will have a material impact on the financial position, liquidity or results of operations of the Company.

Pursuant to the Separation and Distribution Agreement and the Letter Agreement discussed in Notes 4 and 16 to the Consolidated Financial Statements, the Company indemnifies Dow and Corteva for certain environmental matters. The Company has recorded an indemnification liability of $42 million corresponding to the Company's accrual balance related to these matters at December 31, 2019. The indemnification liability is included in the total remediation accrual liability of $77 million.

60

Environmental Capital Expenditures

Capital expenditures for environmental projects, either required by law or necessary to meet the Company’s internal environmental goals, were $33 million for the year ended December 31, 2019. The Company currently estimates expenditures for environmental-related capital projects to be approximately $35 million in 2020.

Climate Change

The Company believes that climate change is an important global issue that presents risks and opportunities. For instance, the Company continuously evaluates opportunities for existing and new product and service offerings to meet the anticipated demands of a low-carbon economy. In 2019, the Company announced nine new sustainability goals, including an Acting on Climate goal to achieve a 30 percent reduction in absolute greenhouse gas (GHG) emissions by 2030 and carbon neutral operations by 2050. DuPont reports on its progress against these goals in its annual sustainability report.

The Company is actively engaged in efforts to develop constructive public policies to reduce GHG emissions and encourage lower-carbon forms of energy. Such policies may bring higher operating costs as well as greater revenue and margin opportunities. Legislative efforts to control or limit GHG emissions could affect the Company's energy source and supply choices as well as increase the cost of energy and raw materials derived from fossil fuels. Such efforts are also anticipated to provide the business community with greater certainty for the regulatory future, help guide investment decisions, and drive growth in demand for low-carbon and energy-efficient products, technologies, and services. Similarly, demand is expected to grow for products that facilitate adaptation to a changing climate. However, the current unsettled policy environment in the U.S., where many company facilities are located, adds an element of uncertainty to business decisions, particularly those relating to long-term capital investments.

In addition, significant differences in regional or national approaches could present challenges in a global marketplace. An effective global climate policy framework will help drive the market changes that are needed to stimulate and efficiently deploy new innovations in science and technology, while maintaining open and competitive global markets.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company’s global operations are exposed to financial market risks relating to fluctuations in foreign currency exchange rates, commodity prices, and interest rates. The Company has established a variety of programs including the use of derivative instruments and other financial instruments to manage the exposure to financial market risks as to minimize volatility of financial results. In the ordinary course of business, the Company enters into derivative instruments to hedge its exposure to foreign currency, interest rate and commodity price risks under established procedures and controls. For additional information on these derivatives and related exposures, see Note 22 to the Consolidated Financial Statements. Decisions regarding whether or not to hedge a given commitment are made on a case-by-case basis, taking into consideration the amount and duration of the exposure, market volatility and economic trends. Foreign currency exchange contracts are also used, from time to time, to manage near-term foreign currency cash requirements.

Foreign Currency Exchange Rate Risks

The Company has significant international operations resulting in a large number of currency transactions that result from international sales, purchases, investments and borrowings. The primary currencies for which the Company has an exchange rate exposure are the European euro ("EUR"), Chinese renminbi, Taiwan dollar, Swiss franc, and South Korean won. The Company uses forward exchange contracts to offset its net exposures, by currency, related to the foreign currency denominated monetary assets and liabilities of its operations. In addition to the contracts disclosed in Note 22 to the Consolidated Financial Statements, from time to time, the Company will enter into foreign currency exchange contracts to establish with certainty the U.S. dollar ("USD") amount of future firm commitments denominated in a foreign currency.

The following table illustrates the fair values of outstanding foreign currency contracts at December 31, 2019, and the effect on fair values of a hypothetical adverse change in the foreign exchange rates that existed at December 31, 2019. The sensitivities for foreign currency contracts are based on a 10 percent adverse change in foreign exchange rates.

	Fair Value Asset/(Liability)			Fair Value Sensitivity
In millions	December 31, 2019			December 31, 2019
Foreign currency contracts	$	(1	)	$	(222	)

Since the Company's risk management programs are highly effective, the potential loss in value for each risk management portfolio described above would be largely offset by changes in the value of the underlying exposure.

Concentration of Credit Risk

The Company maintains cash and cash equivalents, marketable securities, derivatives and certain other financial instruments with various financial institutions. These financial institutions are generally highly rated and geographically dispersed and the Company has a policy to limit the dollar amount of credit exposure with any one institution.

As part of the Company's financial risk management processes, it continuously evaluates the relative credit standing of all of the financial institutions that service DuPont and monitors actual exposures versus established limits. The Company has not sustained credit losses from instruments held at financial institutions.

The Company's sales are not materially dependent on any single customer. As of December 31, 2019, no one individual customer balance represented more than five percent of the Company's total outstanding receivables balance. Credit risk associated with its receivables balance is representative of the geographic, industry and customer diversity associated with the Company's global product lines.

The Company also maintains strong credit controls in evaluating and granting customer credit. As a result, it may require that customers provide some type of financial guarantee in certain circumstances. Length of terms for customer credit varies by industry and region.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company maintains a system of disclosure controls and procedures to give reasonable assurance that information required to be disclosed in the Company's reports filed or submitted under the Securities Exchange Act of 1934 (Exchange Act) is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. These controls and procedures also give reasonable assurance that information required to be disclosed in such reports is accumulated and communicated to management to allow timely decisions regarding required disclosures.

As of December 31, 2019, the Company's Chief Executive Officer (CEO) and Chief Financial Officer (CFO), together with management, conducted an evaluation of the effectiveness of the Company's disclosure controls and procedures pursuant to Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based on that evaluation, the CEO and CFO concluded that these disclosure controls and procedures are effective.

Changes in Internal Control Over Financial Reporting

There were no changes in the Company's internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 and 15d-15 that was conducted during the last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

In connection with the Distributions, there were several processes, policies, operations, technologies and information systems that were integrated following the Merger which have been or will be replicated, transferred or separated. During the quarter ended December 31, 2019, the Company continued to take steps to ensure that adequate controls were designed and maintained throughout this transition period.

The Company has completed its evaluation of its internal controls and has concluded that the Company's system of internal controls over financial reporting was effective as of December 31, 2019 (see page F-2).

ITEM 9B. OTHER INFORMATION

In anticipation of and to facilitate the proposed transaction with IFF, DuPont is planning for the internal separation of the N&B Business, both domestically and internationally, through a series of transactions that are intended to be tax-efficient from both a United States and foreign perspective (collectively, the "N&B Internal Separations"). See Part I, Items 1 and 1A of this report for more information regarding the proposed transaction. The N&B Internal Separations are currently expected to consist of internal transactions undertaken by DuPont and its subsidiaries to separate ownership of the N&B Business from ownership of their other businesses, including a number of distributions intended to qualify as tax-free spinoffs for United States tax purposes under Section 355 of the Internal Revenue Code.

The N&B Internal Separations are expected to occur in the United States and in (or involving entities domiciled in) various jurisdictions, including (but not limited to) China, India and the Netherlands. Following the completion of the N&B Internal Separations, DuPont expects that DuPont will effectuate the separation, pending DuPont Board approval, in a distribution intended to qualify as a tax-free spinoff for United States tax purposes under Section 355 of the Internal Revenue Code.

The DuPont subsidiaries, or their successors, that are included in the current plans for the N&B Internal Separations as distributing corporations in the N&B Internal Separations (each in one or more tax-free spinoffs for United States tax purposes under Section 355 of the Internal Revenue Code) are the following: Rohm and Haas Electronic Materials (Shanghai) Ltd; DDP Specialty Products India Private Limited; Specialty Electronic Materials Netherlands Holding 5, B.V.; Specialty Electronic Materials Netherlands B.V.; DuPont Services Company B.V.; Performance Specialty Products NA, LLC; Specialty Products US 2, LLC; Specialty Products US, LLC; DDP Specialty Electronic Materials US, Inc; Rohm and Haas Electronic Materials CMP Inc; DDP Specialty Electronic Materials US 5, LLC; DDP Specialty Electronic Materials US 4, LLC; DDP Specialty Electronic Materials US 8, LLC; Specialty Products US 4, LLC; and DDP Specialty Electronic Materials US 9, LLC.

Management's Reports on Responsibility for Financial Statements and

Internal Control over Financial Reporting

Management's Report on Responsibility for Financial Statements

Management is responsible for the Consolidated Financial Statements and the other financial information contained in this Annual Report on Form 10-K. The financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") and are considered by management to present fairly the Company's financial position, results of operations and cash flows. The financial statements include some amounts that are based on management's best estimates and judgments. The financial statements have been audited by the Company's independent registered public accounting firms, PricewaterhouseCoopers LLP and Deloitte & Touche LLP. The purpose of their audit is to express an opinion as to whether the Consolidated Financial Statements included in this Annual Report on Form 10-K present fairly, in all material respects, the Company's financial position, results of operations and cash flows in conformity with GAAP. Their reports are presented on the following pages.

Management's Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining an adequate system of internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The Company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. The Company's internal control over financial reporting includes those policies and procedures that:

i. pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

ii. provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles and that receipts and expenditures of the Company are being made only in accordance with authorization of management and directors of the Company; and

iii. provide reasonable assurance regarding prevention or timely detection of unauthorized acquisitions, use or disposition of the Company's assets that could have a material effect on the financial statements.

Internal control over financial reporting has certain inherent limitations which may not prevent or detect misstatements. In addition, changes in conditions and business practices may cause variation in the effectiveness of internal controls.

Management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2019, based on criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in Internal Control-Integrated Framework (2013). Based on its assessment and those criteria, management concluded that the Company maintained effective internal control over financial reporting as of December 31, 2019.

PricewaterhouseCoopers LLP, an independent registered public accounting firm, has audited the effectiveness of the Company's internal control over financial reporting as of December 31, 2019, as stated in their report, which is presented on the following pages.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of DuPont de Nemours, Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheet of DuPont de Nemours, Inc. and its subsidiaries (the “Company”) as of December 31, 2019, and the related consolidated statements of operations, comprehensive income, equity and cash flows for the year then ended, including the related notes and schedule of valuation and qualifying accounts for the year ended December 31, 2019 appearing under Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, based on our audit and the report of other auditors, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2019, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America. Also in our opinion the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

We did not audit the financial statements of The Dow Chemical Company, which was a wholly owned subsidiary prior to the April 1, 2019 distribution discussed in Note 4, which statements reflect, for the period from January 1, 2019 to March 31, 2019, total net sales of $13,582 million (of which $1,604 million is included in continuing operations and $11,978 million is included in discontinued operations in the Company’s consolidated statement of operations) for the period then ended. Those statements were audited by other auditors whose report thereon has been furnished to us, and our opinion expressed herein, insofar as it relates to the amounts included for The Dow Chemical Company for period from January 1, 2019 to March 31, 2019 is based solely on the report of the other auditors.

Change in Accounting Principles

As discussed in Note 1 to the consolidated financial statements, the Company changed the manner in which it accounts for leases and the manner in which it accounts for inventory in 2019.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audit of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit and the report of other auditors provide a reasonable basis for our opinions.

F-3

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Goodwill impairment assessments for certain reporting units

As described in Notes 1 and 14 to the consolidated financial statements, the Company’s consolidated goodwill balance was $33.2 billion as of December 31, 2019. Management conducts impairment tests for goodwill annually during the fourth quarter, or more frequently, if events or circumstances indicate the carrying value of goodwill may be impaired. In the second quarter, management recorded goodwill impairment charges of $933 million and $242 million related to the Industrial Biosciences reporting unit within the Nutrition & Biosciences segment and certain reporting units within the Non-Core segment, respectively. In addition, certain reporting units within the Electronics & Imaging and Non-Core segments had limited headroom between the estimated fair value and the carrying value of the reporting units. Goodwill impairment is identified by comparing the fair value of a reporting unit to its carrying value. Fair value of goodwill is estimated using a combination of a discounted cash flow model and/or market approach.

The principal considerations for our determination that performing procedures relating to the goodwill impairment assessments for certain reporting units is a critical audit matter are (i) there was significant judgment by management when developing the fair value measurements of the reporting units, which in turn led to a high degree of auditor judgment, effort, and subjectivity in performing procedures and in evaluating audit evidence relating to the Company’s discounted cash flow and market approach models and significant assumptions, including the projected revenue, earnings before interest, depreciation and amortization (EBITDA) margins, the weighted average costs of capital, the terminal growth rates, and other market data, (ii) management recorded impairment charges for certain reporting units and certain other reporting units had limited headroom between the estimated fair value and carrying value of the reporting unit, and (iii) the audit effort involved the use of professionals with specialized skill and knowledge to assist in evaluating the audit evidence obtained from these procedures.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s goodwill impairment assessments, including controls over the determination of the fair value of the Company’s reporting units. These procedures also included, among others, evaluating the appropriateness of the models and reasonableness of the significant assumptions used by management in developing the fair value measurements, including the projected revenue, EBITDA margins, the weighted average costs of capital, the terminal growth rates, and other market data. Evaluating the reasonableness of assumptions related to projected revenue and EBITDA margins involved considering the current economic conditions and recent operating results and whether the assumptions used by management were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in evaluating the appropriateness of the Company’s discounted cash flow and market approach models and reasonableness of certain significant assumptions, including the weighted average costs of capital and terminal growth rates.

F-4

Tax-free determination of certain internal distributions and reorganizations and the distributions of Dow, Inc. and Corteva, Inc.

As described in Notes 1 and 4 to the consolidated financial statements, management has determined that certain internal distributions and reorganizations and the distributions of Dow, Inc. (Dow) on April 1, 2019, and Corteva, Inc. (Corteva) on June 1, 2019, qualified as tax-free transactions under the applicable sections of the Internal Revenue Code. As such, the Company is not required to pay corporate taxes on the transactions. The determination of the tax-free nature relating to certain internal distributions and reorganizations and the distributions of Dow and Corteva requires management to make judgments about the application of tax laws and regulations. As disclosed by management, the Internal Revenue Service could determine on audit that either, or both, of the distributions or certain internal reorganizations should be treated as taxable transactions, which would have a material adverse impact on the Company.

The principal considerations for our determination that performing procedures relating to the tax-free determination of certain internal distributions and reorganizations and the distributions of Dow and Corteva is a critical audit matter are (i) there was significant judgment made by management regarding the transactions and the application of tax laws and regulations in determining that certain internal distributions and reorganizations and the distributions of Dow and Corteva qualify for tax-free status, and (ii) the significant impact to the financial statements if the tax-free determinations were determined to be inappropriate by the Internal Revenue Service. This in turn led to a significant degree of auditor judgment and effort in performing procedures and in evaluating audit evidence relating to the tax-free determination of certain internal distributions and reorganizations and the distributions of Dow and Corteva. In addition, the audit effort involved the use of professionals with specialized skill and knowledge to assist in evaluating the audit evidence obtained from these procedures.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the key judgments, including inputs and assumptions, relating to the determination of the tax-free nature of the transactions. These procedures also included, among others, (i) evaluating the information, including third party opinions, tax law, and other relevant evidence used by management to support management’s position that the transactions qualified for tax-free status, and (ii) evaluating certain internal distributions and reorganization transactions implemented prior to the distributions of Dow and Corteva and related tax consequences. Professionals with specialized skill and knowledge were used to assist in the evaluation of the transactions, related assumptions, and certain representations from management, as well as the application of relevant tax laws.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of DuPont de Nemours, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of DuPont de Nemours, Inc. and subsidiaries (the "Company") as of December 31, 2018, the related consolidated statements of income, comprehensive income, equity, and cash flows, for each of the two years in the period ended December 31, 2018, and the related notes and the schedule listed in the Index at Item 15a(2) for the two years ended December 31, 2018 (collectively referred to as the "financial statements"). In our opinion, based on our audits and the report of the other auditors, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2018, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2018, in conformity with accounting principles generally accepted in the United States of America.

We did not audit the consolidated financial statements of E. I. du Pont de Nemours and Company (“EID”), a wholly-owned subsidiary of the Company, which consolidated financial statements reflected total assets of $101,025 million as of December 31, 2018, and total revenues of $26,279 million for the year ended December 31, 2018 and $7,053 million for the period from August 31, 2017 (date of merger) to December 31, 2017. Those statements were audited by other auditors whose report has been furnished to us, and our opinion, insofar as it relates to the amounts included for EID as of December 31, 2018 and for the period from August 31, 2017 (date of the merger) to December 31, 2017 and the year ended December 31, 2018, is based solely on the report of the other auditors.

Changes in Accounting Principles

As discussed in Note 1 to the financial statements, in the first quarter of 2018, the Company changed its method of accounting for revenue due to the adoption of Accounting Standards Codification Topic 606, Revenue From Contracts With Customers. As discussed in Note 1 and Note 11 to the financial statements, the accompanying financial statements have been retrospectively adjusted for a change in the method of accounting for inventory of the specialty products business from last-in, first-out to the average cost method.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits and the report of the other auditors provide a reasonable basis for our opinion.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation and Basis of Presentation

The accompanying Consolidated Financial Statements of DuPont de Nemours, Inc. ("DuPont” or “the Company”) were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The significant accounting policies described below, together with the other notes that follow, are an integral part of the Consolidated Financial Statements.

Effective August 31, 2017, pursuant to the merger of equals transaction contemplated by the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017 ("DWDP Merger Agreement"), The Dow Chemical Company ("Historical Dow") and E. I. du Pont de Nemours and Company ("Historical EID") each merged with subsidiaries of DowDuPont Inc. ("DowDuPont") and, as a result, Historical Dow and Historical EID became subsidiaries of DowDuPont (the "Merger"). Prior to the Merger, DowDuPont did not conduct any business activities other than those required for its formation and matters contemplated by the DWDP Merger Agreement. For purposes of DowDuPont's financial statement presentation, Historical Dow was determined to be the accounting acquirer in the Merger and Historical EID's assets and liabilities are reflected at fair value as of the Merger Effectiveness Time. The financial statements of Historical Dow for periods prior to the Merger are considered to be the historical financial statements of the Company.

Except as otherwise indicated by the context, the term "Historical Dow" includes Historical Dow and its consolidated subsidiaries, "Historical EID" includes Historical EID and its consolidated subsidiaries, and "Dow Silicones" means Dow Silicones Corporation, a wholly owned subsidiary of Historical Dow.

Distributions

Effective as of 5:00 p.m. on April 1, 2019, the Company completed the separation of its materials science business into a separate and independent public company by way of a distribution of Dow Inc. (“Dow”) through a pro rata dividend in-kind of all of the then-issued and outstanding shares of Dow’s common stock (the “Dow Common Stock”), to holders of the Company’s common stock (the “DowDuPont common stock”), as of the close of business on March 21, 2019 (the “Dow Distribution”).

Effective as of 12:01 a.m. on June 1, 2019, the Company completed the separation of its agriculture business into a separate and independent public company by way of a distribution of Corteva, Inc. (“Corteva”) through a pro rata dividend in-kind of all of the then-issued and outstanding shares of Corteva’s common stock (the “Corteva Common Stock”), to holders of the Company’s common stock as of the close of business on May 24, 2019 (the “Corteva Distribution” and, together with the Dow Distribution, the “Distributions”).

Following the Corteva Distribution, DuPont holds the specialty products business as continuing operations. On June 1, 2019, DowDuPont changed its registered name from "DowDuPont Inc." to "DuPont de Nemours, Inc." doing business as "DuPont." Beginning on June 3, 2019, the Company's common stock is traded on the NYSE under the ticker symbol "DD".

These Consolidated Financial Statements present the financial position of DuPont as of December 31, 2019 and 2018 and the results of operations of DuPont for the years ended December 31, 2019, 2018 and 2017 giving effect to the Distributions, with the historical financial results of Dow and Corteva reflected as discontinued operations. The sum of the individual earnings per share amounts from continuing operations and discontinued operations may not equal the total company earnings per share amounts due to rounding. The cash flows and comprehensive income related to Dow and Corteva have not been segregated and are included in the Consolidated Statements of Cash Flows and Consolidated Statements of Comprehensive Income, respectively, for all periods presented. Unless otherwise indicated, amounts or activity of Dow and Corteva are consistently included or excluded from the Notes to the Consolidated Financial Statements based on the respective financial statement line item.

On December 15, 2019, the Company entered into definitive agreements to separate and combine the Nutrition & Biosciences business segment (the "N&B Business") with International Flavors & Fragrances Inc. ("IFF") in a tax-efficient Reverse Morris Trust transaction, (the "Proposed N&B Transaction"). The transaction is expected to close by the end of the first quarter of 2021, subject to approval by IFF shareholders and other customary closing conditions, including regulatory approvals and receipt by DuPont of an opinion of tax counsel. The financial results of the N&B Business are included in continuing operations for the periods presented.

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.

F-15

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, 2019 and 2018, 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.

Reverse Stock Split

On June 1, 2019, immediately following the Corteva Distribution, the Company completed a 1-for-3 reverse stock split of DuPont's outstanding common stock (the "Reverse Stock Split") and as a result, DuPont common stockholders now hold one share of common stock of DuPont for every three shares held prior to the Reverse Stock Split. The authorized number of shares of common stock was reduced from 5,000,000,000 shares to 1,666,666,667 shares, par value remained $0.01 per share. Stockholders entitled to fractional shares as a result of the Reverse Stock Split received a cash payment in lieu of receiving fractional shares. All share and share-related information presented in these Consolidated Financial Statements have been retroactively adjusted in all periods presented to reflect the decreased number of shares resulting from the Reverse Stock Split. The retroactive adjustments resulted in the reclassification of $16 million from "Common stock" to "Additional paid-in capital" in the Consolidated Balance Sheets for all periods presented.

Leases

The Company adopted the Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)" in the first quarter of 2019. 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 "Deferred charges and other assets" on the Consolidated Balance Sheets. Operating lease liabilities are included in "Accrued and other current liabilities" and "Other noncurrent obligations" on the Consolidated Balance Sheets. Finance lease ROU assets are included in "Property, plant and equipment - net" and the corresponding lease liabilities are included in "Short-term borrowings and finance lease obligations" and "Long-term debt" on the Consolidated Balance Sheets.  

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, and lease expense is recognized 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. Additionally, for certain equipment leases, the portfolio approach is applied to account for the operating lease ROU assets and lease liabilities. In the Consolidated Statements of Operations, lease expense for operating lease payments 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 Notes 2 and 17 for additional information regarding the Company's leases.

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

Restricted cash represents trust assets of $37 million and $43 million as of December 31, 2019 and 2018, respectively, and is included within "Other current assets" on the Consolidated Balance Sheets. See Note 7 for further information.

F-16

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.

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 local 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 (local 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 the year, 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 the local currency is the functional currency, assets and liabilities denominated in local 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 loss in equity. Assets and liabilities denominated in other than the local currency are re-measured into the local 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 the period.

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.

Prior to the Corteva Distribution, the Company recorded inventory under the last-in, first-out ("LIFO"), first-in, first-out ("FIFO") and average cost methods. During the second quarter of 2019, effective after the Corteva Distribution, DuPont elected to change the method of accounting for inventories of the specialty products business recorded under the LIFO method to the average cost method. The effects of the change in accounting principle have been retrospectively applied to all prior periods presented. See Note 11 for more information regarding the change in inventory accounting method.

F-17

Approximately 17 percent and 83 percent of the Company's inventories were accounted for under the FIFO and the average cost methods, respectively, at both December 31, 2019 and December 31, 2018. Inventories accounted for under the FIFO method are primarily comprised of products with shorter shelf lives such as certain food-ingredients and enzymes. The Company establishes allowances for obsolescence of 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 annually during the fourth quarter, 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.

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. The Company determines fair values for each of the reporting units using a combination of the income approach and/or 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. Under the market approach, the Company selected peer sets based on close competitors and reviewed the EBIT/EBITDA multiples to determine the fair value. See Note 14 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's fair value methodology is primarily based on discounted cash flow techniques.

Definite-lived intangible assets are amortized over their estimated useful lives, generally on a straight-line basis for periods ranging primarily from 1 to 26 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.

Impairment and Disposals 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 or loss is reported in "Accumulated other comprehensive loss" ("AOCL") until it is cleared to earnings during the same period in which the hedged item affects earnings.

F-18

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 AOCL generally remains in AOCL 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.

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 5 for additional information on revenue recognition.

Cost of Sales

Cost of sales 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 and other operational expenses. No amortization of intangibles is included within costs of sales.

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, enhancement of existing products and regulatory approval of new and existing products.

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, the Distributions, and beginning in the fourth quarter of 2019, the intended separation of the Nutrition & Biosciences business. 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

Accruals for legal matters 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.

F-19

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.

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 Company accrues for other tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated. The current portion of uncertain income tax positions is included in income taxes payable and the long-term portion is included in other noncurrent obligations in the Consolidated Balance Sheets.

NOTE 2 - RECENT ACCOUNTING GUIDANCE

Recently Adopted Accounting Guidance

In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, Leases (Topic 842), and associated ASUs related to Topic 842, which requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. The new guidance requires that a lessee recognize assets and liabilities for leases, and recognition, presentation and measurement in the financial statements depends on whether the lease is classified as a finance or operating lease. In addition, the new guidance requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. Lessor accounting remains largely unchanged from previous U.S. GAAP but does contain some targeted improvements to align with the new revenue recognition guidance, referred to as "Topic 606," issued in 2014.

The Company adopted the new standard in the first quarter of 2019, which allows for a modified retrospective transition approach, applying the new standard to all leases existing at the date of initial adoption. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statement as its date of initial application. The Company has elected to apply the transition requirements at the January 1, 2019 effective date rather than at the beginning of the earliest comparative period presented. This approach allows for a cumulative effect adjustment in the period of adoption, and prior periods are not restated and continue to be reported in accordance with historic accounting under ASC 840 (Leases). In addition, the Company has elected the package of practical expedients permitted under the transition guidance within the new standard which does not require reassessment of prior conclusions related to contracts containing a lease, lease classification and initial direct lease costs. As an accounting policy election, the Company chose to not apply the standard to certain existing land easements, excluded short-term leases (term of 12 months or less) from the balance sheet and accounts for nonlease and lease components in a contract as a single component for all asset classes. The following table summarizes the impact of adoption to the Consolidated Balance Sheet:

1. The as reported December 31, 2018 information has been updated to reflect the impact of the reverse stock split and the change in accounting policy discussed in Note 1.

2. The net impact to retained earnings was primarily a result of the recognition of a deferred gain associated with a prior sale-leaseback transaction.

The adoption of the new guidance did not have a material impact on the Company's Consolidated Statement of Operations and had no impact on the Consolidated Statement of Cash Flows.

In August 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Topic 715-20), Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. This amendment modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans by removing and adding certain disclosures for these plans. The eliminated disclosures include the amounts in "Accumulated Other Comprehensive Income" expected to be recognized in net periodic benefit costs over the next fiscal year and the effects of a one-percentage-point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for postretirement health care benefits. New disclosures include the interest crediting rates for cash balance plans, and an explanation of significant gains and losses related to changes in benefit obligations. The new standard is effective for fiscal years beginning after December 15, 2020, and must be applied retrospectively for all periods presented. Early adoption is permitted. The Company early adopted the new guidance in the fourth quarter of 2019, and adoption did not have a material impact on the Consolidated Financial Statements.

Accounting Guidance Issued But Not Adopted at December 31, 2019

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and associated ASUs related to Topic 326. The new guidance introduces the current expected credit loss (“CECL”) model, which requires organizations to record an allowance for credit losses for certain financial instruments and financial assets, including trade receivables, based on expected losses rather than incurred losses. Under this update, on initial recognition and at each reporting period, an entity will be required to recognize an allowance that reflects the entity’s current estimate of credit losses expected to be incurred over the life of the financial instrument. This update will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, and early adoption is permitted.

The Company has a cross-functional team in place to evaluate and implement the new guidance and the Company has substantially completed the implementation of the standard to be in compliance with accounting and reporting requirements. The team continues to review existing financial instruments and update business processes and controls related to the new guidance for credit losses. Collectively, these activities are expected to facilitate the Company's ability to meet the new accounting and disclosure requirements upon adoption in the first quarter of 2020.

The ASU requires a modified retrospective transition approach, applying the new standards cumulative-effect adjustment as of the beginning of the first reporting period in which the guidance is effective. Therefore, this cumulative-effect will be reflected as of January 1, 2020 and prior periods will not be restated. The Company is finalizing the evaluation of the January 1, 2020 impact and estimates that the impact to the Company’s Consolidated Balance Sheet will not be material. The impact to the Company's Consolidated Statements of Operations and Consolidated Statement of Cash Flows is expected not to be material.

NOTE 3 - BUSINESS COMBINATIONS

Merger of Equals of Historical Dow and Historical EID

At the effective time of the Merger, each share of common stock, par value $2.50 per share, of Historical Dow ("Historical Dow Common Stock") (excluding any shares of Historical Dow Common Stock that were held in treasury immediately prior to the effective time of the Merger, which were automatically canceled and retired for no consideration) was converted into the right to receive one fully paid and non-assessable share of common stock, par value $0.01 per share, of DowDuPont ("DowDuPont Common Stock"). Upon completion of the Merger, (i) each share of common stock, par value $0.30 per share, of Historical EID (“Historical EID Common Stock”) (excluding any shares of Historical EID Common Stock that were held in treasury immediately prior to the effective time of the Merger, which were automatically canceled and retired for no consideration) was converted into the right to receive 1.2820 fully paid and non-assessable shares of DowDuPont Common Stock, in addition to cash in lieu of any fractional shares of DowDuPont Common Stock, and (ii) each share of Historical EID Preferred Stock $4.50 Series and Historical EID Preferred Stock $3.50 Series (collectively, the “Historical EID Preferred Stock”) issued and outstanding immediately prior to the effective time of the Merger remains issued and outstanding and was unaffected by the Merger. The Historical EID Preferred Stock was separated from the Company at the time of the Corteva Distribution.

As provided in the DWDP Merger Agreement, at the effective time of the Merger, Historical Dow stock options and other equity awards were generally automatically converted into stock options and equity awards with respect to DowDuPont Common Stock and Historical EID stock options and other equity awards, after giving effect to the exchange ratio, were converted into stock options and equity awards with respect to DowDuPont Common Stock, and otherwise generally on the same terms and conditions under the applicable plans and award agreements immediately prior to the effective time of the Merger. See Notes 18 and 21 for additional information.

Allocation of Purchase Price

Based on an evaluation of the provisions of Accounting Standards Codification ("ASC") 805, "Business Combinations" ("ASC 805"), Historical Dow was determined to be the accounting acquirer in the Merger. DowDuPont applied the acquisition method of accounting with respect to the assets and liabilities of Historical EID, which were measured at fair value as of the date of the Merger.

Historical EID's assets and liabilities were measured at estimated fair values at August 31, 2017, primarily using Level 3 inputs. Estimates of fair value represent management's best estimate and require a complex series of judgments about future events and uncertainties. Third-party valuation specialists were engaged to assist in the valuation of these assets and liabilities.

At the time of the Merger, the total fair value of consideration transferred was $74,680 million. Total consideration is comprised of the equity value of the DowDuPont shares at August 31, 2017, that were issued in exchange for Historical EID shares, the cash value for fractional shares, and the portion of Historical EID's share awards and share options earned at August 31, 2017. Share awards and share options converted to DowDuPont equity instruments, but not vested, were $144 million at August 31, 2017, which was expensed over the remaining future vesting period.

The following table provides "Net sales" and "Loss from continuing operations before income taxes" related to Historical EID's specialty products business which are included in the Company's continuing operations results for the period September 1 through December 31, 2017. Included in the results from Historical EID was $92 million of "Restructuring and asset related charges - net", $1,320 million that was recognized in "Cost of sales" as inventory was sold related to the fair value step-up of inventories and $220 million of "Integration and separation costs" in the Consolidated Statement of Operations.

Unaudited Supplemental Pro Forma Information

The unaudited pro forma results presented below were prepared pursuant to the requirements of ASC 805 and give effect to the Merger as if it had been consummated on January 1, 2016. The pro forma results do not necessarily represent what the revenue or results of operations would have been had the Merger been completed on January 1, 2016, are not intended to be a projection of future operating results and do not reflect synergies that might be achieved by the Company. In addition, amounts below have been revised to give effect to the discontinued operations of Dow and Corteva.

The pro forma results include adjustments for the purchase accounting impact (including, but not limited to, depreciation and amortization associated with the acquired tangible and intangible assets, amortization of the fair value adjustment to investment in nonconsolidated affiliates, and reduction of interest expense related to the fair value adjustment to long-term debt, along with the related tax impacts), the alignment of accounting policies, and the elimination of transactions between Historical Dow and Historical EID. Costs incurred to prepare for the Merger have been excluded from the 2017 pro forma results presented below based on an assumption they were incurred in 2016. The costs incurred related to integration and to prepare for the Distributions are reflected in the pro forma results. In addition, the Company incurred an after-tax charge of $1,038 million in 2017 related to the fair value step-up of inventories acquired and sold. The 2017 pro forma results were adjusted to exclude this charge based on an assumption the charge was incurred in 2016.

The unaudited pro forma results for all periods presented below exclude the results of operations of the businesses reflected as discontinued operations.

Acquisition of H&N Business

On March 31, 2017, Historical EID entered into a definitive agreement (the "FMC Transaction Agreement") with FMC Corporation ("FMC") for FMC to acquire the assets related to Historical EID's crop protection business and research and development ("R&D") organization (the "Divested Ag Business") that Historical EID was required to divest in order to obtain European Commission ("EC") approval of the Merger Transaction. In addition, under the FMC Transaction Agreement, Historical EID agreed to acquire certain assets relating to FMC’s Health and Nutrition segment, excluding its Omega-3 products (the "H&N Business") (the sale of the Divested Ag Business and acquisition of the H&N Business referred to collectively as the "FMC Transactions"). See Note 4 for further discussion of the Divested Ag Business.

On November 1, 2017, Historical EID completed the FMC Transactions through the acquisition of the H&N Business and the divestiture of the Divested Ag Business. The acquisition was integrated into Nutrition & Biosciences to enhance the Company’s position as a leading provider of sustainable, bio-based food ingredients and allow for expanded capabilities in the pharma excipients space. Historical EID accounted for the acquisition in accordance with ASC 805, which requires the assets acquired and liabilities assumed to be recognized on the balance sheet at their fair values as of the acquisition date. Total consideration of the H&N Business was $1,970 million.

The Company evaluated the disclosure requirements under ASC 805 and determined the H&N Business was not considered a material business combination for purposes of disclosing the revenue and earnings of the H&N Business since the date of acquisition or supplemental pro forma information.

2019 Acquisitions

During the fourth quarter of 2019, DuPont completed acquisitions of the following, all within the Safety & Construction segment:

• inge GmbH, an ultrafiltration membrane business from BASF,

• Memcor, the ultrafiltration and membrane bioreactor technologies division from Evoqua Water Technologies Corp.,

• OxyMem Limited, a company that develops and produces Membrane Aerated Biofilm Reactor technology.

The aggregate purchase price of the above acquisitions was approximately $175 million and was primarily allocated to goodwill, other intangibles and property, plant and equipment.

Separation Agreements

In connection with the Dow Distribution and the Corteva Distribution, the Company has entered into certain agreements that, among other things, effect the separations, provide for the allocation of assets, employees, liabilities and obligations (including its investments, property and employee benefits and tax-related assets and liabilities) among DuPont, Dow, and Corteva (together, the “Parties” and each a “Party”), and provide a framework for DuPont’s relationship with Dow and Corteva following the Distributions. Effective April 1, 2019, the Parties entered into the following agreements:

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

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

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

• Intellectual Property Cross-License Agreement - DuPont entered into an Intellectual Property Cross-License Agreement with Dow (the “DuPont-Dow IP Cross-License Agreement”). The DuPont-Dow IP Cross-License Agreement sets forth the terms and conditions under which the applicable Parties may use in their respective businesses, following each of the Distributions, certain know-how (including trade secrets), copyrights, software, and certain patents and standards, allocated to another Party pursuant to the Separation and Distribution Agreement.

In addition to the agreements above, DuPont has entered into certain various supply agreements with Dow. These agreements provide for different pricing than the historical intercompany and intracompany practices prior to the Distributions.

Effective June 1, 2019, in connection with the Corteva Distribution, DuPont and Corteva entered into the following agreements:

• Intellectual Property Cross-License Agreement - DuPont and Corteva entered into an Intellectual Property Cross-License Agreement (the “DuPont-Corteva IP Cross-License Agreement”). The DuPont-Corteva IP Cross-License Agreement sets forth the terms and conditions under which the applicable parties may use in their respective businesses, following the Corteva Distribution, certain know-how (including trade secrets), copyrights, software, and certain patents and standards, allocated to another Party pursuant to the Separation and Distribution Agreement.

• Letter Agreement - The Company entered into a letter agreement (the "Letter Agreement") with Corteva that sets forth certain additional terms and conditions related to the Corteva Distribution, including certain limitations on DuPont’s and Corteva's ability to transfer certain businesses and assets to third parties without assigning certain of such Party’s indemnification obligations under the Separation and Distribution Agreement to the other Party to the transferee of such businesses and assets or meeting certain other alternative conditions. The Letter Agreement further outlines the allocation between DuPont and Corteva of liabilities associated with certain legal and environmental matters, including liabilities associated with discontinued and/or divested operations and businesses of Historical EID. See Note 16 for more information regarding the allocation.

• Amended and Restated Tax Matters Agreement - The Parties entered into an amendment and restatement of the Tax Matters Agreement, between DuPont, Corteva and Dow, effective as of April 1, 2019 (as so amended and restated, the “Amended and Restated Tax Matters Agreement”). The Amended and Restated Tax Matters Agreement governs the Parties’ rights, responsibilities and obligations with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and other matters regarding taxes. The Parties amended and restated the Tax Matters Agreement in connection with the Corteva Distribution in order to allocate between DuPont and Corteva certain rights and obligations of the Company provided in the original form of the Tax Matters Agreement. See Note 8 for additional information on the Tax Matters Agreement and the Amended and Restated Tax Matters Agreement.

Management has determined that certain internal distributions and reorganizations, and the distributions of Dow on April 1, 2019, and of Corteva on June 1, 2019, qualified as tax-free transactions under the applicable sections of the Internal Revenue Code. If the completed distribution of Corteva or Dow, in each case, together with certain related transactions, were to fail to qualify for non-recognition treatment for U.S. federal income tax purposes, then the Company could be subject, under the Tax Matters Agreement, to significant tax and indemnification liability. To the extent that the Company is responsible for any liability under

F-24

the Amended and Restated Tax Matters Agreement there could be a material adverse impact on the Company's business, financial condition, results of operations and cash flows in future reporting periods.

NOTE 5 - REVENUE

Revenue Recognition

Products

Substantially all of DuPont's revenue is derived from product sales. Product sales consist of sales of DuPont's products to supply manufacturers and distributors. DuPont 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.

Revenue from product sales is recognized when the customer obtains control of the Company’s product, which occurs at a point in time, usually upon shipment, with payment terms typically in the range of 30 to 60 days after invoicing depending on business and geographic region. The Company elected the practical expedient to not adjust the amount of consideration for the effects of a significant financing component for all instances in which the period between payment and transfer of the goods will be one year or less. When the Company performs shipping and handling activities after the transfer of control to the customer (e.g., when control transfers prior to 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. The Company elected to use the practical expedient to expense cash and non-cash sales incentives as the amortization period for the costs to obtain the contract would have been one year or less.

F-29

The transaction price includes estimates for reductions in revenue from customer rebates and rights of return on product sales. These amounts are estimated based upon the most likely amount of consideration to which the customer will be entitled. All estimates are based on historical experience, anticipated performance, and the Company’s best judgment at the time to the extent it is probable, that a significant reversal of revenue recognized will not occur. All estimates for variable consideration are reassessed periodically.

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.

Disaggregation of Revenue

The Company disaggregates its revenue from contracts with customers by segment and business or major product line and geographic region, as the Company believes it best depicts the nature, amount, timing and uncertainty of its revenue and cash flows. Refer to Note 24 for the breakout of net sales by geographic region.

On June 1, 2019, the Company realigned certain businesses resulting in changes to its management and reporting structure, including the creation of a new Non-Core segment ("Second Quarter Segment Realignment") (refer to Note 24 for additional details). In conjunction with the Second Quarter Segment Realignment, DuPont made the following changes to its major product lines:

• Realigned its product lines within Nutrition & Biosciences as Food & Beverage, Health & Biosciences, and Pharma Solutions;

• Renamed its product lines within Transportation & Industrial (formerly known as Transportation & Advanced Polymers) as Mobility Solutions, Healthcare & Specialty, and Industrial & Consumer (formerly known as Engineering Polymers, Performance Solutions, and Performance Resins, respectively); and

• Realigned and renamed its product lines within Safety & Construction as Safety Solutions, Shelter Solutions, and Water Solutions.

On October 1, 2019, Electronics & Imaging realigned its product lines as Image Solutions, Interconnect Solutions and Semiconductor Technologies.

Contract Balances

From time to time, the Company enters into arrangements in which it receives payments from customers based upon contractual billing schedules. The Company records accounts receivables when the right to consideration becomes unconditional. Contract assets include amounts related to the Company’s contractual right to consideration for completed performance obligations not yet invoiced. Contract liabilities primarily reflect deferred revenue from advance payment for product that the Company has received from customers. The Company classifies deferred revenue as current or noncurrent based on the timing of when the Company expects to recognize revenue.

Revenue recognized for the years ended December 31, 2019 and 2018 from amounts included in contract liabilities at the beginning of the period was $40 million and $37 million, respectively. The amount of contract assets reclassified to receivables as a result of the right to the transaction consideration becoming unconditional was insignificant. The Company did not recognize any asset impairment charges related to contract assets during the period.

At December 31, 2018, $129 million was included in "Accrued and other current liabilities" and $13 million was included in "Other noncurrent obligations" in the Consolidated Balance Sheets.

Equity Method Investment Impairment Related Charges

During the second quarter of 2019, in preparation for the Corteva Distribution, Historical EID completed the separation of the assets and liabilities related to its specialty products businesses into separate legal entities (the “SP Legal Entities”) and on May 1, 2019, Historical EID distributed the SP Legal Entities to DowDuPont (the “Internal SP Distribution”). The Internal SP Distribution served as a triggering event requiring the Company to perform an impairment analysis related to equity method investments held by the Company as of May 1, 2019. The Company applied the net asset value method under the cost approach to determine the fair value of the equity method investments in the Nutrition & Biosciences segment. Based on updated projections, the Company determined the fair value of the equity method investment was below the carrying value and had no expectation the fair value would recover in the short-term due to the current economic environment. As a result, management concluded the impairment was other-than-temporary and recorded an impairment charge of $63 million in “Restructuring and asset related charges - net” in the second quarter of 2019. This impairment charge related to the Nutrition & Biosciences segment. See Notes 14 and 23 for additional information.

Other Impairment Related Charges

In the fourth quarter of 2017, the Company recognized other pretax impairment charges of $71 million, including charges related to manufacturing assets. The impairment charges were included in "Restructuring and asset related charges - net" in the Consolidated Statements of Operations and related to Electronics & Imaging ($39 million) and Safety & Construction ($32 million).

1. The year ended December 31, 2019 includes income of $92 million, related to a sale of assets within the Electronics & Imaging segment and as well as a gain of $28 million related to the sale of the Sustainable Solutions business unit within the Non-Core segment.

2. Includes a $50 million foreign exchange loss for the year ended December 31, 2018 related to adjustments to Historical EID's foreign currency exchange contracts as a result of U.S. tax reform.

3. Miscellaneous income and expenses - net, for the year ended December 31, 2019 includes a $48 million charge reflecting a reduction in gross proceeds from lower withholding taxes related to a prior year legal settlement and a $74 million charge related to tax indemnifications, primarily associated with an adjustment to a one-time transition tax liability required by the Tax Cuts and Jobs Act of 2017, which were recorded in accordance with the Amended and Restated Tax Matters Agreement. These charges were offset by various indemnification and lease income amounts. The miscellaneous income for the year ended 2018 primarily relates to legal settlements.

Cash, Cash Equivalents and Restricted Cash

The Company is required to set aside funds for various activities that arise in the normal course of business. These funds typically have legal restrictions associated with them and are deposited in an escrow account or held in a separately identifiable account by the Company. Historical EID entered into a trust agreement in 2013 (as amended and restated in 2017), establishing and requiring Historical EID to fund a trust (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. After the Corteva Distribution, the Trust assets related to Corteva employees were transferred to a new trust for Corteva (the "Corteva Trust"). As a result, the Trust currently held by DuPont relates to funding obligations to DuPont employees. At December 31, 2019, the Company had restricted cash of $37 million ($43 million at December 31, 2018) included in "Other current assets" in the Consolidated Balance Sheets which was completely attributed to the Trust.

F-33

Accrued and Other Current Liabilities

"Accrued and other current liabilities" in the Consolidated Balance Sheets were $1,342 million at December 31, 2019 and $1,129 million at December 31, 2018. Accrued payroll, which is a component of "Accrued and other current liabilities," was $479 million at December 31, 2019 and $506 million at December 31, 2018. No other components of "Accrued and other current liabilities" were more than five percent of total current liabilities.

NOTE 8 - INCOME TAXES

For periods between the Merger and the Distributions, DuPont's consolidated federal income tax group and consolidated tax return included the Dow and Corteva entities. Generally, the consolidated tax liability of the DuPont U.S. tax group for each year was apportioned among the members of the consolidated group in accordance with the terms of the Amended and Restated Tax Matters Agreement. DuPont, Corteva and Dow intend that to the extent Federal and/or State corporate income tax liabilities are reduced through the utilization of tax attributes of the other, settlement of any receivable and payable generated from the use of the other party’s sub-group attributes will be in accordance with the Amended and Restated Tax Matters Agreement.

On December 22, 2017, the Tax Cuts and Jobs Act (“The Act”) was enacted. The Act reduced the U.S. federal corporate income tax rate from 35 percent to 21 percent, required companies to pay a one-time transition tax on earnings of foreign subsidiaries that were previously tax deferred, created new provisions related to foreign sourced earnings, eliminates the domestic manufacturing deduction and moves towards a territorial system. At December 31, 2018, the Company had substantially completed its accounting for the tax effects of The Act.

• As a result of The Act, the Company remeasured its U.S. federal deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21 percent. In prior years, the Company recorded a cumulative benefit of $2,784 million ($118 million benefit in 2018 and $2,666 million benefit in 2017) to “Provision (Credit) for income taxes on continuing operations” in the Consolidated Statements of Operations with respect to the remeasurement of the Company's deferred tax balances.

• The Act required a mandatory deemed repatriation of post-1986 undistributed foreign earnings and profits (“E&P”), which results in a one-time transition tax. The Company recorded a cumulative net charge of $1,574 million ($65 million benefit in 2019, $59 million charge in 2018, and $1,580 million charge in 2017) to "Provision (Credit) for income taxes on continuing operations" with respect to the one-time transition tax.

• In the year ended December 31, 2018, the Company recorded an indirect impact of The Act related to prepaid tax on the intercompany sale of inventory. The amount recorded related to the inventory was a $54 million charge to "Provision for income taxes on continuing operations."

Each year the Company files hundreds of tax returns in the various national, state and local income taxing jurisdictions in which it operates. These tax returns are subject to examination and possible challenge by the tax authorities. Positions challenged by the tax authorities may be settled or appealed by the Company. As a result, there is an uncertainty in income taxes recognized in the Company’s financial statements in accordance with accounting for income taxes and accounting for uncertainty in income taxes. The ultimate resolution of such uncertainties is not expected to have a material impact on the Company's results of operations.

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

Undistributed earnings of foreign subsidiaries and related companies that are deemed to be permanently invested amounted to $7,823 million at December 31, 2019. In addition, the U.S. federal tax imposed by The Act on all accumulated unrepatriated earnings through December 31, 2017, The Act introduced additional U.S. federal tax on foreign earnings, effective as of January 1, 2018. The undistributed foreign earnings at December 31, 2019 may still be subject to certain taxes upon repatriation, primarily where foreign withholding taxes apply. It is not practicable to calculate the unrecognized deferred tax liability on undistributed foreign earnings due to the complexity of the hypothetical calculation.

NOTE 9 - EARNINGS PER SHARE CALCULATIONS

On May 23, 2019, stockholders of DowDuPont approved a reverse stock split of the Company's common stock at a ratio of not less than 2-for-5 and not greater than 1-for-3, with the exact ratio determined by and subject to final approval of the Company’s board of directors. The board of directors approved the Reverse Stock Split with a ratio of 1 new share of DowDuPont common stock for 3 shares of current DowDuPont common stock with par value of $0.01 per share. The Reverse Stock Split became effective immediately following the Corteva Distribution on June 1, 2019. All comparable periods presented have been retrospectively revised to reflect this change.

The following tables provide earnings per share calculations for the years ended December 31, 2019, 2018 and 2017:

Weighted-average common shares - diluted 3	746.3	771.8	532.7
Stock options and restricted stock units excluded from EPS calculations 4	3.3	3.2	0.5

1. Historical Dow restricted stock units are considered participating securities due to Historical Dow's practice of paying dividend equivalents on unvested shares.

2. Earnings per share amounts are computed independently for income from continuing operations, income from discontinued operations and net income attributable to common stockholders. As a result, the per share amounts from continuing operations and discontinued operations may not equal the total per share amounts for net income attributable to common stockholders.

3. As a result of the Merger, the share amounts for the year ended December 31, 2017 reflect a weighted averaging effect of Historical Dow shares outstanding prior to August 31, 2017 and DowDuPont shares outstanding on and after August 31, 2017.

4. These outstanding options to purchase shares of common stock and restricted stock units were excluded from the calculation of diluted earnings per share because the effect of including them would have been antidilutive.

Effective June 1, 2019, after the Corteva Distribution, the Company changed its method of valuing certain inventories of the specialty products business from the LIFO method to the average cost method. Management believes that the change in accounting is preferable as it results in a consistent method to value inventory across all regions of the business, it improves comparability with industry peers, and it more closely resembles the physical flow of inventory. The effects of the change in accounting principle from LIFO to average cost have been retrospectively applied to all periods presented. This change resulted in an increase to "(Accumulated Deficit) Retained Earnings" of $21 million as of January 1, 2017.  

In addition, certain financial statement line items in the Company’s Consolidated Statement of Operations for the year ended December 31, 2017 were adjusted as follows:

1. DC HSC Holdings LLC holds an 80.5 percent percent indirect ownership interest in Hemlock Semiconductor Operations LLC.

Sales to nonconsolidated affiliates represented less than 3 percent of total net sales for the year ended December 31, 2019 and 2018, and approximately 4 percent of total net sales for the year ended December 31, 2017. Sales to nonconsolidated affiliates are primarily related to the sale of trichlorosilane, a raw material used in the production of polycrystalline silicon, to the HSC Group. Sales of this raw material to the HSC Group are reflected in Non-Core. Purchases from nonconsolidated affiliates represented less than 2 percent of “Cost of sales” in 2019, 2018, and 2017.

HSC Group

The carrying value of the Company's investments in the HSC Group, which represents Hemlock Semiconductor L.L.C. and DC HSC Holdings LLC, was adjusted as a result of the HSC Group's adoption of Topic 606 on January 1, 2019 in accordance with the effective date of Topic 606 for non-public companies. The resulting impact to the Company's investments in the HSC Group was a reduction to "Investment in nonconsolidated affiliates" of $71 million and an increase to "Other noncurrent obligations" of $168 million, as well as an increase to "Deferred income tax assets" of $56 million and a reduction to "(Accumulated Deficit) Retained earnings" of $183 million in the Consolidated Balance Sheet at January 1, 2019.

The Company's investment in and equity earnings from the HSC Group are shown in the tables below:

NOTE 14 - GOODWILL AND OTHER INTANGIBLE ASSETS

The following table summarizes changes in the carrying amount of goodwill for the years ended December 31, 2019 and 2018. After the completion of the Distributions, the Company changed its reportable segments. Prior year data has been updated to conform with the current year presentation for changes in reportable segments discussed in Note 24.

1. On November 1, 2017, Historical EID acquired FMC's H&N Business. The excess of the consideration for the H&N Business over the net fair value of assets acquired and liabilities assumed resulted in the recognition of $732 million of goodwill, of which $14 million was recorded in 2018 as a measurement period adjustment.

2. The prior year amounts have been revised for a reclassification of allocated goodwill between reporting units.

The Company tests goodwill for impairment annually during the fourth quarter, or more frequently when events or changes in circumstances indicate that the fair value is below its carrying value. As a result of the related acquisition method of accounting in connection with the Merger, Historical EID’s assets and liabilities were measured at fair value resulting in increases to the Company’s goodwill and other intangible assets. The fair value valuation increased the risk that any declines in financial projections, including changes to key assumptions, could have a material, negative impact on the fair value of the Company’s reporting units and assets, and therefore could result in an impairment.

In preparation for the Corteva Distribution, Historical EID completed the separation of the assets and liabilities related to its specialty products businesses into separate legal entities (the “SP Legal Entities”) and on May 1, 2019, Historical EID completed the Internal SP Distribution. The Internal SP Distribution served as a triggering event requiring the Company to perform an impairment analysis related to goodwill carried by its Historical EID existing reporting units as of May 1, 2019. Subsequent to the Corteva Distribution, on June 1, 2019, the Company realigned certain businesses resulting in changes to its management and reporting structure, including the creation of a new Non-Core segment. As part of the Second Quarter Segment Realignment, the Company assessed and re-defined certain reporting units effective June 1, 2019, including reallocation of goodwill on a relative fair value basis as applicable to new reporting units identified. Goodwill impairment analyses were then performed for reporting units impacted by the Second Quarter Segment Realignment.

In connection with the analyses described above, the Company recorded aggregate, pre-tax, non-cash impairment charges of $1,175 million for the year ended December 31, 2019 impacting the Nutrition & Biosciences and Non-Core segments. As part of this analysis, the Company determined that the fair value of its Industrial Biosciences reporting unit was below carrying value resulting in a pre-tax, non-cash goodwill impairment charge of $933 million. The Industrial Biosciences reporting unit, part of the Nutrition & Biosciences segment prior to the Second Quarter Segment Realignment, was comprised solely of Historical EID assets and liabilities, the carrying values of which were measured at fair value in connection with the Merger, and thus considered at risk for impairment. Revised financial projections of the Industrial Biosciences reporting unit reflected unfavorable market conditions, driven by slowed demand in the biomaterials business unit which was realigned to the new Non-Core segment effective June 1, 2019, coupled with challenging conditions in U.S. bioethanol markets. These revised financial projections resulted in a reduction in the long-term forecasts of sales and profitability as compared to prior projections. The $242 million in goodwill impairment charges impacting the Non-Core segment also relates to multiple reporting units comprised solely of Historical EID assets and liabilities, the carrying values of which were measured at fair value in connection with the Merger, and thus considered at risk for impairment. The impairment charges impacting Non-Core were determined through utilization of the market approach which was considered most appropriate as the Company continues to evaluate strategic options for these businesses. As a result of the impairment, these Non-Core reporting units' carrying value are indicative of fair value and are at risk to have impairment charges in future periods.

F-43

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

In the fourth quarter of 2019, the Company performed quantitative testing on all of its reporting units and determined that no further impairments existed. The Company used a combination of discounted cash flow models (a form of the income approach) utilizing Level 3 unobservable inputs and the Guideline Public Company Method (a form of the market approach). The Company’s significant assumptions in these analyses include, but are not limited to, projected revenue, EBITDA margins, the weighted average cost of capital, the terminal growth rate, derived multiples from comparable market transactions and other market data. As of the fourth quarter testing date, a reporting unit within the Electronics & Imaging segment had limited headroom between the estimated fair value and the carrying value. Subsequent to the fourth quarter testing date, in connection with the Electronics & Imaging realignment of its product lines, this reporting unit is now a part of different reporting unit. The new reporting unit is not considered at risk for impairment.

The weighted-average interest rate on notes payable and commercial paper at December 31, 2019 and December 31, 2018 was 2.79 percent and 8.25 percent, respectively. The decrease in the interest rate from 2018 is primarily due to commercial paper issuance at lower interest rates. The Company issued $1,829 million of commercial paper for the year ended December 31, 2019, of which approximately $1,400 million was issued in anticipation of the Corteva Distribution (the “Funding CP Issuance”).

Senior Notes

In contemplation of the Distributions and in preparation to achieve the intended credit profiles of Corteva, Dow and DuPont, in the fourth quarter of 2018, the Company consummated a public underwritten offer of eight series of senior unsecured notes (the "2018 Senior Notes") in an aggregate principal amount of $12.7 billion. The 2018 Senior Notes are a senior unsecured obligation of the Company and will rank equally with the Company's future senior unsecured debt outstanding from time to time. On November 1, 2018, the Company announced a $3 billion share buyback program, which expired on March 31, 2019. In the first quarter of 2019, proceeds from the 2018 Senior Notes were used to purchase $1.6 billion of shares. As a result, the share buyback program was complete at March 31, 2019.

Term Loan and Revolving Credit Facilities

In May 2019, the Company fully drew the two term loan facilities it entered into in the fourth quarter of 2018 (the “Term Loan Facilities”) in the aggregate principal amount of $3,000 million. In May 2019, the Company amended its $3,000 million five-year revolving credit facility (the “Five-Year Revolver”) entered into in the fourth quarter of 2018 to become effective and available as of the amendment. In addition, in June 2019, the Company entered into a $750 million, 364-day revolving credit facility (the "364-day Revolving Credit Facility"). The Company intends to renew the 364-Day Revolving Credit Facility on or prior to expiration.

Uncommitted Credit Facilities and Outstanding Letters of Credit

Unused bank credit lines on uncommitted credit facilities were $566 million at December 31, 2019. 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, 2019. These letters of credit support commitments made in the ordinary course of business.

Debt Covenants and Default Provisions

The Company's indenture covenants include customary limitations on liens, sale and leaseback transactions, and mergers and consolidations, subject to certain limitations. The 2018 Senior Notes also contain customary default provisions. The Term Loan

Facilities, the Five-Year Revolving Credit Facility and the 364-Day Revolving Credit Facility contain a financial covenant requiring that the ratio of Total Indebtedness to Total Capitalization for the Company and its consolidated subsidiaries not exceed 0.60. At December 31, 2019, the Company was in compliance with this financial covenant. There were no material changes to the debt covenants and default provisions at December 31, 2019.

F-46

Nutrition & Biosciences Financing

In connection with the Proposed N&B Transaction, DuPont and Nutrition & Biosciences, Inc. (presently a wholly owned subsidiary of DuPont) (“N&B Inc.”) entered into a Bridge Commitment Letter (the “Bridge Letter”) in an aggregate principal amount of $7.5 billion (the “Bridge Loans”) to secure committed financing for the Special Cash Payment and related financing fees. The aggregate commitment under the Bridge Letter is reduced by, among other things, (1) the amount of net cash proceeds received by N&B Inc. from any issuance of senior unsecured notes pursuant to a Rule 144A offering or other private placement (the "N&B Notes Offering") and (2) certain qualifying term loan commitments under senior unsecured term loan facilities.

In January 2020, N&B Inc. entered into a senior unsecured term loan agreement in the amount of $1.25 billion split evenly between three- and five-year facilities. As a result of entry into the term loan agreement, the commitments under the Bridge Commitment Letter were reduced to $6.25 billion. The remaining $6.25 billion is expected to be funded through the N&B Notes Offering and/or the Bridge Loans. The proceeds from drawdowns on the term loan facilities and the N&B Notes Offering, if any, and/or Bridge Loans would be used to make the Special Cash Payment and to pay the related transaction fees and expenses. The commitments under the Bridge Letter and the availability of funding under the term loan are subject to customary closing conditions including among others, the satisfaction of substantially all the conditions to the consummation of the proposed transaction with IFF.

NOTE 16 - COMMITMENTS AND CONTINGENT LIABILITIES

Litigation and Environmental Matters

As of December 31, 2019, the Company had recorded liabilities of $20 million associated with litigation matters and $77 million associated with environmental matters. These recorded liabilities include the Company’s indemnification obligations to each of Dow and Corteva.

Under the Separation and Distribution Agreement, liabilities, including cost and expenses, associated with litigation and environmental matters that primarily related to the materials science business, the agriculture business or the specialty products business were generally allocated to or retained by Dow, Corteva or the Company, respectively, through retention, assumption or indemnification. Related to the foregoing, at December 31, 2019, DuPont has recorded (i) a liability of $35 million (although it is reasonably possible that the ultimate cost could range up to $108 million above the amount accrued) for retained or assumed environmental liabilities, (ii) a liability of $3 million for retained or assumed litigation liabilities, and (iii) an indemnification liability related to legal and environmental matters of $58 million. Liabilities associated with discontinued and/or divested operations and businesses of Historical Dow generally were allocated to or retained by Dow. The allocation of liabilities associated with the discontinued and/or divested operations and businesses of Historical EID is discussed below.

The liabilities allocated to and assumed by Dow and Corteva are reflected as discontinued operations of the Company at December 31, 2018. Such liabilities assumed by Dow as of the consummation of the Dow Distribution on April 1, 2019 include the following: Asbestos-Related Matters of Union Carbide Corporation, Urethane Matters, Rocky Flats Matter, Dow Silicones Chapter 11 Related Matters, Midland Off-Site Environmental Matters, Dow Silicones Midland, Michigan, Freeport, Texas, Plaquemine, Louisiana and St. Charles, Louisiana Steam-Assisted Flares Matters, Freeport, Texas, Facility Matter, Mt. Meigs, Alabama Matter, Union Carbide Matter and Union Carbide - Seadrift, Texas and, with indemnity from DuPont and Corteva, the Sabine Plant, Orange Texas-EPA Multimedia Inspection. Such liabilities assumed by Corteva as of the consummation of the Corteva Distribution on June 1, 2019, include the following: La Porte Plant, La Porte, Texas - Crop Protection-Release Incident Investigation and La Porte Plant, La Porte, Texas - EPA Multimedia Inspection.

Discontinued and/or Divested Operations and Businesses ("DDOB") Liabilities of Historical EID

Under the Separation and Distribution Agreement and the Letter Agreement between Corteva and DuPont, DDOB liabilities of Historical EID primarily related to Historical EID’s agriculture business were allocated to or retained by Corteva and those primarily related to Historical EID’s specialty products business were allocated to or retained by the Company. Historical EID DDOB liabilities not primarily related to Historical EID’s agriculture business or specialty products business (“Stray Liabilities”), are allocated as follows

• Generally, indemnifiable losses as defined in the Separation and Distribution Agreement, (“Indemnifiable Losses”) for Stray Liabilities, to the extent they do not arise out of actions related to or resulting from the development, testing, manufacture or sale of PFAS, defined below, (“Non-PFAS Stray Liabilities”) that are known as of April 1, 2019 are borne by Corteva up to a specified amount set forth in the schedules to the Separation and Distribution Agreement and/or Letter Agreement. Non-PFAS Stray Liabilities in excess of such specified amounts and any Non-PFAS Stray Liabilities not listed in the schedules to the Separation and Distribution Agreement or Letter Agreement are borne by Corteva and/or DuPont up to separate, aggregate thresholds of $200 million each to the extent Corteva or DuPont, as applicable, incurs an Indemnifiable Loss. Once Corteva’s or DuPont’s $200 million threshold is met, the other

F-47

would generally bear all Non-PFAS Stray Liabilities until meeting its $200 million threshold. After the respective $200 million thresholds are met, DuPont will bear 71 percent of such losses and Corteva will bear 29 percent of such losses.

• Generally, Corteva and the Company will each bear 50 percent of the first $300 million (up to $150 million each) for Indemnifiable Losses arising out of actions to the extent related to or resulting from the development, testing, manufacture or sale of per- or polyfluoroalkyl substances, which include collectively perfluorooctanoic acids and its salts (“PFOA”), perfluorooctanesulfonic acid (“PFOS”) and perfluorinated chemicals and compounds (“PFCs”) (all such substances, “PFAS” and such Stray Liabilities referred to as “PFAS Stray Liabilities”). Indemnifiable Losses to the extent related to PFAS Stray Liabilities in excess of $300 million generally will be borne 71 percent by the Company and 29 percent by Corteva, unless either Corteva or DuPont has met its $200 million threshold. In that event, the other company would bear all PFAS Stray Liabilities until that company meets its $200 million threshold, at which point DuPont will bear 71 percent of such losses and Corteva will bear 29 percent of such losses.

• Indemnifiable Losses incurred by the companies in relation to PFAS Stray Liabilities up to $300 million (e.g., up to $150 million each) will be applied to each company’s respective $200 million threshold.

Non-PFAS Stray Liabilities

While DuPont believes it is probable that it will incur a liability related to Non-PFAS Stray Liabilities, such liability is not reasonably estimable at December 31, 2019. Therefore, at December 31, 2019, DuPont has not recorded an accrual related to Non-PFAS Liabilities.

PFAS Stray Liabilities

DuPont expects to continue to incur costs and expenses such as attorneys’ fees and expenses and court costs in connection with the matters described below, which the Company will expense as incurred in accordance with its accounting policy for litigation matters.

Chemours Suit

On July 1, 2015, Historical EID completed the separation of Historical EID’s Performance Chemicals segment through the spinoff of all the issued and outstanding stock of The Chemours Company (“Chemours”) to holders of Historical EID common stock. In connection with the spin, Historical EID and Chemours entered into a Separation Agreement (as amended, the "Chemours Separation Agreement"). Pursuant to the Chemours Separation Agreement, Chemours is obligated to indemnify Historical EID, including its current or former affiliates, against certain litigation, environmental and other liabilities that arose prior to the Chemours Separation. 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, Historical EID and Chemours amended the Chemours Separation Agreement to provide for a limited sharing of potential future PFOA liabilities for a five-year period that began on July 6, 2017. The amended agreement provides that during that five-year period, Chemours will annually pay the first $25 million of future PFOA liabilities and, if that amount is exceeded, Historical EID will pay any excess amount up to the next $25 million, with Chemours annually bearing any excess liabilities above that amount. If Historical EID were required to pay PFOA liabilities pursuant to the amended agreement, fifty percent of such obligation would be borne by the Company in accordance with the Letter Agreement. In connection with the foregoing, the Company has not recorded or paid a PFOA liability. At the end of the five-year period, this limited sharing agreement will expire, and Chemours’ indemnification obligations under the Chemours Separation Agreement will continue unchanged.

On May 13, 2019, Chemours filed suit in the Delaware Court of Chancery against Historical EID, Corteva and the Company in an attempt to limit its responsibility for the litigation and environmental liabilities allocated to and assumed by Chemours under the Chemours Separation Agreement. Chemours is asking the court to rewrite the Chemours Separation Agreement by either limiting Chemours’ liabilities or, alternatively, ordering the return to Chemours of all or a portion of a $3.91 billion dividend that Chemours paid to Historical EID, Chemours’ then-sole-shareholder, just prior to the spin of Chemours. DuPont and Corteva, acting jointly, have filed a motion to dismiss the lawsuit for lack of subject matter jurisdiction and have initiated an arbitration of the dispute as required under the Chemours Separation Agreement. In December 2019, following argument, the Delaware Court of Chancery stayed arbitration pending resolution of the motion to dismiss. The court is expected to rule on the motion in the first quarter of 2020. Indemnifiable Losses related to the Chemours suit are PFAS Stray Liabilities subject to the sharing arrangement between DuPont and Corteva, described above. The Company believes the probability of a final unappealable judgment of liability with respect to the Chemours suit to be remote; the defendants continue to vigorously defend full indemnity rights as set forth in the Chemours Separation Agreement.

PFAS Matters

Historical EID is a party to legal proceedings relating to the use of PFOA and PFCs by its former Performance Chemicals segment. Indemnifiable Losses related to PFAS liabilities allocated to and assumed by Chemours under the Chemours Separation Agreement generally are PFAS Stray Liabilities subject to the sharing arrangement between DuPont and Corteva, described above.

Generally, Chemours, with reservations, including as to alleged fraudulent conveyance and voidable transactions, is defending and indemnifying Historical EID in the PFAS Matters discussed below. Although Chemours has refused the tender of the Company’s defense in the limited actions in which the Company has been named, DuPont believes it is remote that it will ultimately incur a liability in connection with these PFAS Matters.

Personal Injury and Other PFAS Actions

DuPont, which was formed after the spinoff of Chemours, is not named in the personal injury and other PFAS actions discussed below.

Personal Injury

In 2004, Historical EID settled a West Virginia state court class action, Leach v. DuPont, which alleged that PFOA from Historical EID’s former Washington Works facility had contaminated area drinking water supplies and affected the health of area residents. Historical EID has residual liabilities under the Leach settlement related to 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.

Members of the Leach class have standing to pursue personal injury claims for just six health conditions that an expert panel appointed under the Leach 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. In 2017, Chemours and Historical EID each paid $335 million to settle the multi-district litigation in the U.S. District Court for the Southern District of Ohio (“Ohio MDL”), thereby resolving claims of about 3,550 plaintiffs alleging injury from exposure to PFOA in drinking water. The 2017 settlement did not resolve claims of Leach class members who did not have claims in the Ohio MDL or whose claims are based on diseases first diagnosed after February 11, 2017. To date several dozen claims alleging personal injury, including kidney and testicular cancer claims, have been filed since the 2017 settlement. These claims are currently pending in the Ohio MDL. Trial of a kidney cancer claim and a testicular cancer claim began in the first quarter of 2020 and trial of additional cancer claims are scheduled to begin in June 2020.

Natural Resource Damage Claims and Other Claims for Environmental Damages

In addition to the actions described above, there are about 100 cases alleging damages to natural resources, the environment and/or property as well as various other allegations. DuPont which is named in certain of these actions as discussed below, is increasingly named in suits filed since May 2019.

Drinking Water

Since May 2017, a number of municipal water districts and state attorneys general have filed lawsuits against Historical EID, Chemours, 3M, and others, claiming contamination of public water systems by certain PFAS compounds. Such actions are currently pending in Ohio, Michigan, New Jersey, New Hampshire, New York, and Vermont. Generally, the states seek economic impact damages for alleged harm to natural resources, punitive damages, and present and future costs to cleanup contamination from certain PFAS compounds and to abate the alleged nuisance.

DuPont is a named party in the New Jersey suit related to its site in Parlin, New Jersey. In addition, the New Jersey Attorney General and New Jersey State Department of Environmental Protection filed two directives, one of which names DuPont. The directives seek information on the historical and current use of PFAS. DuPont is also a named party to the Vermont suit and the Michigan suit. The amended complaints in the New Jersey and Vermont cases and the complaint filed by Michigan include additional causes of action based on allegations that the transfer by Historical EID of certain PFAS liabilities to Chemours prior to spinning off Chemours resulted in a fraudulent conveyance or voidable transaction.

Lawsuits have been filed by residents and several water districts against Historical EID and Chemours in New York federal and state courts, including a putative class action, alleging exposure to PFOA from third-party defendant manufacturing operations and seeking compensatory, consequential and punitive damages, medical monitoring and attorneys’ fees, expenses and interest.

F-49

Other PFAS Actions

There are several actions pending in federal court against Historical EID and Chemours, relating to discharges of PFCs, including GenX, into the Cape Fear River. GenX is a polymerization processing aid and a replacement for PFOA introduced by Historical EID which Chemours continues to manufacture at its Fayetteville Works facility in Bladen County, North Carolina. One of these actions is a consolidated putative class action that asserts claims for damages and other relief 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. In addition, an action is pending in North Carolina state court on behalf of about 100 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.

Aqueous Film Forming Foam

As of January 2020, more than 200 cases have been filed in various federal and state courts alleging contamination of neighboring drinking and groundwater from the use of aqueous film forming foam to fight fires on military installations, air force bases, commercial airports and refineries. The majority of these cases have been transferred, or will be transferred, to a multi-district litigation docket in federal district court in South Carolina (the “SC MDL”). Historical EID and Chemours are named in about 150 of these cases, approximately 100 of which also name the Company. The number of cases filed that name as a defendant, the Company, among others including Historical EID and Chemours, has increased significantly since May 2019. In addition, most of these more recent cases were filed directly in the SC MDL and include allegations that exposure to PFAS caused kidney, testicular and other cancers principally in firefighters. 3M and several foam manufacturers are also named defendants in the SC MDL cases. The claims against Historical EID and Chemours involve alleged sales of PFOA and PFOS products to foam manufacturers, including 3M, who are also defendants in the SC MDL. Historical EID and the Company have never made or sold aqueous film forming foam, PFOS or PFOS containing products.

Additionally, a case filed by a former firefighter is pending in the Southern District of Ohio seeking certification of a nationwide class of individuals who have detectable levels of PFAS in their blood serum. The suit was filed against 3M and several other defendants in addition to Chemours and Historical EID. The complaint specifically seeks, among other things, the creation of a “PFAS Science Panel” to study the effects of PFAS, but expressly states that the class does not seek compensatory damages for personal injuries. In February 2020, the court denied the defendants' motion to transfer this case to the SC MDL.

Other Litigation Matters

In addition to the specific matters described above, the Company is party to other claims and lawsuits arising out of the normal course of business with respect to product liability, patent infringement, governmental regulation, contract and commercial litigation, and other actions. Certain of these actions may purport to be class actions and seek damages in very large amounts. It is the opinion of the Company’s management that the possibility is remote that the aggregate of all such other claims and lawsuits will have a material adverse impact on the results of operations, financial condition and cash flows of the Company.

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 based on current law and existing technologies. At December 31, 2019, the Company had accrued obligations of $77 million for probable environmental remediation and restoration costs, inclusive of $35 million retained and assumed following the Distributions and $42 million of indemnified liabilities. These obligations are included in "Accrued and other current liabilities" and "Other noncurrent obligations" in the 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 $170 million above the amount accrued at December 31, 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. At December 31, 2018, the Company had accrued obligations of $51 million for probable environmental remediation and restoration costs.

Pursuant to the Separation and Distribution Agreement, the Company is required to indemnify certain clean-up responsibilities and associated remediation costs. The accrued environmental obligations of $77 million as of December 31, 2019 includes amount for which the Company indemnifies Dow and Corteva. At December 31, 2019, the Company has indemnified Dow and Corteva $8 million and $34 million, respectively.

F-50

Guarantees

Obligations for Equity Affiliates & Others

The Company has directly guaranteed various debt obligations under agreements with third parties related to equity affiliates and customers. At December 31, 2019 and December 31, 2018, the Company had directly guaranteed $187 million and $199 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. The Company would be required to perform on these guarantees in the event of default by the guaranteed party.

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.

In certain cases, the Company has recourse to assets held as collateral, as well as personal guarantees from customers. Assuming liquidation, these assets are estimated to cover approximately 19 percent of the $22 million of guaranteed obligations of customers. The following table provides a summary of the final expiration year and maximum future payments for each type of guarantee:

Guarantees at December 31, 2019	Final Expiration Year	Maximum Future Payments
In millions
Obligations for customers 1:
Bank borrowings	2020	$	22
Obligations for non-consolidated affiliates2:
Bank borrowings	2020	165
Total guarantees		$	187

1. Existing guarantees for select customers, as part of contractual agreements. The terms of the guarantees are equivalent to the terms of the customer loans that are primarily made to finance customer invoices. Of the total maximum future payments, $22 million had terms less than a year.

2. Existing guarantees for non-consolidated affiliates' liquidity needs in normal operations.

NOTE 17 - LEASES

The Company has operating and finance leases for real estate, an airplane, railcars, fleet, certain machinery and equipment, and information technology assets. The Company’s leases have remaining lease terms of approximately 1 year to 40 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 is included in the related lease liability in the Consolidated Balance Sheet other than certain finance leases that include the maximum residual value guarantee amount in the measurement of the related liability given the election to use the package of practical expedients at the date of adoption. At December 31, 2019, the Company has future maximum payments for residual value guarantees in operating leases of $19 million with final expirations through 2031. The Company's lease agreements do not contain any material restrictive covenants.

The components of lease cost for operating and finance leases for the year ended December 31, 2019 were as follows:

Operating lease ROU assets and lease 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.

NOTE 18 - STOCKHOLDERS' EQUITY

On May 23, 2019, stockholders of DowDuPont approved a 1-for-3 reverse stock split of DowDuPont shares of common stock with par value of $0.01 per share, which became effective immediately following the Corteva Distribution on June 1, 2019. All comparable periods presented have been retrospectively revised to reflect this change.

Share Repurchase Program

On June 1, 2019, the Company's Board of Directors approved a new $2 billion share buyback program, which expires on June 1, 2021. For the year ended December 31, 2019, the Company had repurchased and retired 10.8 million shares under this program at a total cost of $750 million.

NOTE 20 - PENSION PLANS AND OTHER POST EMPLOYMENT BENEFITS

Historical Dow and Historical EID did not merge their defined benefit pension and other post employment benefit (OPEB) plans as a result of the Merger. See Note 3 for additional information on the Merger. In connection with the Distributions, the Historical Dow U.S. qualified defined benefit plan and the Historical EID U.S. principal qualified defined benefit plan were separated from the Company to Dow and Corteva, respectively. The defined benefit pension plans that were related to Historical Dow that were not separated with Dow or Corteva were not merged with any Historical EID plans. The Company retained a portion of pension liabilities relating to foreign benefit plans for both Historical EID and Historical Dow. The Company retained select OPEB liabilities relating to foreign Historical EID benefit plans but did not retain any Historical Dow OPEB plans. The Company also retained an immaterial portion of the non-qualified US pension liabilities and other post employment benefit plans relating to Historical EID US benefit plans. The significant defined benefit pension and OPEB plans of Historical Dow and Historical EID are summarized below.

Defined Benefit Pension Plans

Historical Dow

Historical Dow had both funded and unfunded defined benefit pension plans that covered employees in the United States and a number of other countries. The U.S. qualified plan covering the parent company was the largest plan. Benefits for employees hired before January 1, 2008, were based on length of service and the employee’s three highest consecutive years of compensation. Employees hired after January 1, 2008, earned benefits based on a set percentage of annual pay, plus interest.

The Employee Matters Agreement with Dow provides that employees of Dow no longer participate in benefit plans sponsored or maintained by the Company, and that employees of the Company no longer participate in benefit plans sponsored or maintained by Dow, as of the effective time of the Dow Distribution. The U.S. qualified plan is no longer an obligation of the Company, the fundings, maintenance and ultimate payout of the plan is the sole responsibility of Dow. Historical Dow's funding policy was to contribute to the plans when pension laws and/or economics either require or encourage funding.

The Company has both funded and unfunded defined benefit pension plans that cover employees in a number of non-US countries.

Historical EID

Historical EID had both funded and unfunded noncontributory defined benefit pension plans covering a majority of the U.S. employees. The U.S. qualified plan was the largest pension plan held by Historical EID. Most employees hired on or after January 1, 2007, were not eligible to participate in the U.S. defined benefit pension plans. The benefits under these plans were based primarily on years of service and employees' pay near retirement. Historical EID froze the pay and service amounts used to calculate pension benefits for employees who participated in the U.S. pension plans as of November 30, 2018. Therefore, as of November 30, 2018, employees that participated in the U.S. pension plans no longer accrued additional benefits for future service and eligible compensation received.

The Employee Matters Agreement with Corteva provides that employees of Corteva no longer participate in benefit plans sponsored or maintained by the Company, and that employees of the Company no longer participate in benefit plans sponsored or maintained by Corteva, as of the effective time of the Corteva Distribution. The U.S. qualified plan is no longer an obligation of the Company; the fundings, maintenance and ultimate payout of the plan is the sole responsibility of Corteva Inc. The Company has both funded and unfunded defined benefit pension plans that cover executives in the United States and employees in a number of non-US countries.

Historical EID's funding policy was consistent with the funding requirements of federal laws and regulations. Pension coverage for employees of Historical EID's non-U.S. consolidated subsidiaries was 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. Total 2019 contributions also includes contributions to fund benefit payments for Historical EID's pension plans where funding is not customary.

DuPont

DuPont has both funded and unfunded defined benefit pension plans covering employees in a number of non-US countries that formerly relate to both Historical Dow and Historical EID. The United Kingdom qualified plan is the largest pension plan held by DuPont.

F-57

DuPont's funding policy is consistent with the funding requirements of each country's laws and regulations. Pension coverage for employees of DuPont'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. During 2019, the Company contributed $697 million to its pension plans, which included $139 million of contributions to plans that were separated in connection with the Distributions. DuPont expects to contribute approximately $85 million to its pension plans in 2020.

The weighted-average assumptions used to determine pension plan obligations and net periodic benefit costs for all plans are summarized in the table below:

Weighted-Average Assumptions for Pension Plans	Benefit Obligations  at December 31,				Net Periodic Costs for the Years Ended
	2019		2018		2019 1		2018		2017 2
Discount rate	1.21	%	3.80	%	3.80	%	3.26	%	3.50	%
Interest crediting rate for applicable benefits	1.25	%	3.72	%	3.72	%	3.61	%	3.45	%
Rate of compensation increase 3	3.14	%	3.42	%	3.42	%	3.95	%	3.88	%
Expected return on plan assets	—		—		6.46	%	6.68	%	6.94	%

1. Includes three months of Dow activity (January - March), five months of Corteva activity (January - May) and twelve months of DuPont activity, all based on dates of the Distributions.

2. Includes Historical EID plans subsequent to the Merger date.

3. The December 31, 2018 rate did not include Historical EID's U.S. pension plans as employees of these plans no longer accrued additional benefits for future service and eligible compensation.

Other Post employment Benefit Plans

Historical Dow

Historical Dow provided certain health care and life insurance benefits to retired employees and survivors. Historical Dow’s plans outside of the United States were not significant; therefore, this discussion relates to the U.S. plans only. The plans provide health care benefits, including hospital, physicians’ services, drug and major medical expense coverage, and life insurance benefits. In general, for employees hired before January 1, 1993, the plans provide benefits supplemental to Medicare when retirees are eligible for these benefits. Historical Dow and the retiree share the cost of these benefits, with the Historical Dow portion increasing as the retiree has increased years of credited service, although there was a cap on the Historical Dow portion. Historical Dow had the ability to change these benefits at any time. Employees hired after January 1, 2008, are not covered under the plans.

The Employee Matters Agreement with Dow provides that employees of Dow no longer participate in benefit plans sponsored or maintained by the Company, and that employees of the Company no longer participate in benefit plans sponsored or maintained by Dow, as of the effective time of the Dow Distribution.

No Historical Dow other post-employment benefit plans were retained by the Company in connection with the Dow Distribution. All other post-employment benefit plans both those inside the US and those outside, are the sole responsibility of Dow.

Historical EID

Historical EID provided medical, dental and life insurance benefits to pensioners and survivors. The associated plans for retiree benefits were unfunded and the cost of the approved claims was paid from Historical EID company funds. Essentially 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 pensioners and survivors' contributions adjusted annually to achieve a 50/50 target for sharing of cost increases between Historical EID and pensioners and survivors. In addition, limits were applied to Historical EID's portion of the retiree medical cost coverage. For Medicare eligible pensioners and survivors, Historical EID provided a funded Health Reimbursement Arrangement ("HRA"). In November 2016, Historical EID announced that OPEB eligible employees who will be under the age of 50 as of November 30, 2018, as defined above, will not receive post-employment medical, dental and life insurance benefits. Beginning January 1, 2015, eligible employees who retire on and after that date will receive the same life insurance benefit payment, regardless of the employee's age or pay. The majority of U.S. employees hired on or after January 1, 2007, are not eligible to participate in the post-employment medical, dental and life insurance plans.

The Employee Matters Agreement with Corteva provides that employees of Corteva no longer participate in benefit plans sponsored or maintained by the Company, and that employees of the Company no longer participate in benefit plans sponsored or maintained by Corteva, as of the effective time of the Corteva Distribution. The vast majority of U.S. other post employment benefit obligations are no longer the obligations of the Company; the fundings, maintenance and ultimate payout of the plans are the sole responsibility of Corteva Inc.

F-58

DuPont

The Company retained U.S. and foreign other post employment benefit obligations with the Canadian plan being the largest plan and accounting for the vast majority of the Company's total other post employment benefit obligations. In comparison to the Company's defined benefit pension plans, the Company's other post-employment benefit plans are not significant.

The weighted-average assumptions used to determine other post-employment benefit obligations and net periodic benefit costs are provided below:

Weighted-Average Assumptions for Other Postretirement Benefits Plans	Benefit Obligations  at December 31,				Net Periodic Costs for the Year Ended
	2019		2018		2019 1		2018		2017 2

Historical EID plans	N/A		2028		2028		2023		2023

1. Includes three months of Dow activity (January - March), five months of Corteva activity (January - May) and twelve months of DuPont activity, all based on dates of the Distributions.

2. Includes Historical EID plans subsequent to the Merger date.

Assumptions

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.

Service cost and interest cost for all other plans are determined on the basis of the discount rates derived in determining those plan obligations.The discount rates utilized to measure the majority of pension and other postretirement obligations are based on the Aon AA corporate bond yield curves applicable to each country at the measurement date. DuPont utilizes the mortality tables and generational mortality improvement scales, where available, developed in each of the respective countries in which the Company holds plans.

A significant component of the overall decrease in the Company's actuarial losses for the year ended December 31, 2019 was due to the Distributions and the spins of the Company's main US plans. The increase in the Company's actuarial losses for the year ended December 31, 2018 was primarily due to the changes in weighted-average discount rates, which increased from 3.26 percent at December 31, 2017 to 3.80 at December 31, 2018.

The accumulated benefit obligation for all pension plans was $4.5 billion and $51.4 billion at December 31, 2019 and 2018, respectively.

Plan Assets

Historical Dow

Plan assets consist primarily of equity and fixed income securities of U.S. and foreign issuers, and include alternative investments such as real estate, private market securities and absolute return strategies. At December 31, 2018, plan assets totaled $22.5 billion and included no directly held common stock of DowDuPont.

Historical Dow's investment strategy for the plan assets was to manage the assets in relation to the liability in order to pay retirement benefits to plan participants over the life of the plans. This was accomplished by identifying and managing the exposure to various market risks, diversifying investments across various asset classes and earning an acceptable long-term rate of return consistent with an acceptable amount of risk, while considering the liquidity needs of the plans.

The plans were permitted to use derivative instruments for investment purposes, as well as for hedging the underlying asset and liability exposure and rebalancing the asset allocation. The plans used value-at-risk, stress testing, scenario analysis and Monte Carlo simulations to monitor and manage both the risk within the portfolios and the surplus risk of the plans.

Equity securities primarily included investments in large- and small-cap companies located in both developed and emerging markets around the world. Fixed income securities included investment and non-investment grade corporate bonds of companies diversified across industries, U.S. treasuries, non-U.S. developed market securities, U.S. agency mortgage-backed securities, emerging market securities and fixed income related funds. Alternative investments primarily included investments in real estate, private equity limited partnerships and absolute return strategies. Other significant investment types included various insurance contracts and interest rate, equity, commodity and foreign exchange derivative investments and hedges.

Historical Dow mitigated the credit risk of investments by establishing guidelines with investment managers that limit investment in any single issue or issuer to an amount that was not material to the portfolio being managed. These guidelines were monitored for compliance both by Historical Dow and external managers. Credit risk related to derivative activity was mitigated by utilizing multiple counterparties, collateral support agreements and centralized clearing, where appropriate.

Historical EID

Plan assets consisted primarily of equity and fixed income securities of U.S. and foreign issuers, and included alternative investments such as real estate and private market securities. At December 31, 2018, plan assets totaled $18.9 billion and included directly held common stock of DowDuPont of $684 million.

Historical EID established 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 were selected in accordance with the laws and practices of those countries. Where appropriate, asset liability studies were utilized in this process. U.S. plan assets and a portion of non-U.S. plan assets are managed by investment professionals employed by Historical EID. The remaining assets are managed by professional investment firms unrelated to Historical EID. Historical EID's pension investment professionals had discretion to manage the assets within established asset allocation ranges approved by management. Additionally, pension trust funds were permitted to enter into certain contractual arrangements generally described as derivative instruments. Derivatives were primarily used to reduce specific market risks, hedge currency and adjust portfolio duration and asset allocation in a cost-effective manner.

F-62

Global equity securities include varying market capitalization levels. U.S. equity investments are primarily large-cap companies. 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.

DuPont

Plan assets consist primarily of equity and fixed income securities of U.S. and foreign issuers, and alternative investments such as pooled investment vehicles and private market securities. At December 31, 2019, plan assets totaled $3.8 billion and included directly held common stock of DuPont of less than $1 million.

The Company 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.

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. Alternative investments primarily included investments in real estate, various insurance contracts and interest rate, equity, commodity and foreign exchange derivative investments and hedges. Other investments include cash and cash equivalents, pooled investment vehicles, hedge funds and private market securities such as interests in private equity and venture capital partnerships.

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

Target Allocation for Plan Assets at December 31, 2019	DuPont
Asset Category
Equity securities	25	%
Fixed income securities	19
Alternative investments	10
Other investments	46
Total	100	%

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 other pension plan assets for which observable inputs are used, fair value is derived through the use of fair value models, such as a discounted cash flow model or other standard pricing models.

F-63

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.

Certain pension plan assets are held in funds where fair value is based on an estimated net asset value per share (or its equivalent) as of the most recently available fund financial statements which are received 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 to arrive at an estimated net asset value per share at the measurement date. Where available, audited annual financial statements are obtained and reviewed for the investments as support for the manager’s investment valuation. These funds are not classified within the fair value hierarchy.

The following table summarizes the bases used to measure the Company’s pension plan assets at fair value for the years ended December 31, 2019 and 2018:

Trust Assets

Historical EID entered into a trust agreement in 2013 (as amended and restated in 2017) that established and required Historical EID to fund a trust (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. After the distribution of Corteva, the Trust assets related to Corteva employees were transferred to a new trust for Corteva. As a result, the Trust currently held by DuPont relates solely to funding obligations to DuPont employees. At December 31, 2019, the balance in the Trust was $37 million compared to $43 million at December 31, 2018.

Defined Contribution Plans

Historical Dow

U.S. employees participated in defined contribution plans (Employee Savings Plans or 401(k) plans) by contributing a portion of their compensation, which was partially matched by Historical Dow. Defined contribution plans also covered employees in some subsidiaries in other countries, including Australia, Brazil, Canada, Italy, Spain and the United Kingdom. Expense recognized for all defined contribution plans was $242 million in 2018 and $367 million in 2017.

Historical EID

Historical EID provided defined contribution benefits to its employees. The most significant was the U.S. Retirement Savings Plan ("the Plan"), which covered all U.S. full-service employees. This Plan included a non-leveraged Employee Stock Ownership Plan ("ESOP"). Employees were not required to participate in the ESOP and those who did were free to diversify out of the ESOP. The purpose of the Plan was to provide retirement savings benefits for employees and to provide employees an opportunity to become stockholders of the Company. The Plan was a tax qualified contributory profit sharing plan, with cash or deferred arrangement and any eligible employee of Historical EID could participate. Historical EID's contributions to the Plan were $183 million in 2018 and post-Merger contributions were $53 million in 2017. Historical EID's matching contributions vested immediately upon contribution. The 3 percent nonmatching employer contribution vested after employees completed three years of service.

In addition, Historical EID made contributions to other defined contribution plans of $51 million in 2018 and post-Merger contributions to other defined contribution plans of $17 million in 2017.

F-65

DuPont

The Company provides defined contribution benefits to its employees. The most significant is the U.S. Retirement Savings Plan ("the Plan"), which covers all 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 the Company may participate. Currently, the Company 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. The Company's matching contributions vest immediately upon contribution. The 3 percent nonmatching employer contribution vests after employees complete three years of service. The Company's contributions to the Plan in 2019 related to continuing operations were $82 million.

In addition, the Company made contributions to other defined contribution plans in 2019 in the amount of $24 million related to continuing operations.

NOTE 21 - STOCK-BASED COMPENSATION

On May 23, 2019, stockholders of DowDuPont approved a reverse stock split of DowDuPont shares of common stock. DowDuPont's Board of Directors established a reverse stock split ratio of 1 new share of DowDuPont common stock for every 3 shares of current DowDuPont common stock with par value of $0.01 per share. The stock split became effective immediately following the Corteva Distribution on June 1, 2019. All comparable periods presented have been retrospectively revised to reflect this change.

Effective with the Merger, on August 31, 2017, DowDuPont assumed all Historical Dow and Historical EID equity incentive compensation awards outstanding immediately prior to the Merger. The fair values of the converted awards were based on valuation assumptions developed by management and other information including, but not limited to, historical volatility and exercise trends of Historical Dow and Historical EID. All outstanding Historical Dow stock options and restricted stock unit ("RSU") (formerly termed deferred stock) awards were converted into stock options and RSU awards with respect to DowDuPont Common Stock. All outstanding and nonvested Historical Dow performance stock unit ("PSU") (formerly termed performance deferred stock) awards were converted into RSU awards with respect to DowDuPont Common Stock at the greater of the applicable performance target or the actual performance as of the effective time of the Merger.

In addition, the Company also assumed sponsorship of each equity incentive compensation plan of Historical Dow and Historical EID. Historical Dow and Historical EID did not merge their equity incentive plans as a result of the Merger. The Historical Dow and Historical EID stock-based compensation plans were assumed by DowDuPont and remained in place with the ability to grant and issue DowDuPont common stock until the Distributions. Immediately following the Corteva Distribution, DuPont adopted the DuPont Omnibus Incentive Plan ("DuPont OIP") which provides for equity-based and cash incentive awards to certain employees, directors, independent contractors and consultants. Upon adoption of the DuPont OIP, the Historical Dow and Historical EID plans were maintained and rolled into the DuPont OIP as separate subplans. The equity awards under these subplans have the same terms and conditions that were applicable to the awards under the Historical Dow and Historical EID plans immediately prior to the Distributions.

A description of the Company's stock-based compensation is discussed below followed by a description of Historical Dow and Historical EID stock-based compensation.

Accounting for Stock-Based Compensation

The Company grants stock-based compensation awards that vest over a specified period or upon employees meeting certain performance and/or retirement eligibility criteria. The fair value of equity instruments issued to employees is measured on the grant date. The fair value of liability instruments issued to employees is measured at the end of each quarter. The fair value of equity and liability instruments is expensed over the vesting period or, in the case of retirement, from the grant date to the date on which retirement eligibility provisions have been met and additional service is no longer required. The Company estimates expected forfeitures.

DuPont recognized share-based compensation expense in continuing operations of $106 million, $92 million and $19 million during the years ended December 31, 2019, 2018 and 2017, respectively. The income tax benefits related to stock-based compensation arrangements were $22 million, $19 million and $4 million for the years ended December 31, 2019, 2018 and 2017, respectively.

F-66

Total unrecognized pretax compensation cost related to nonvested stock option awards of $23 million at December 31, 2019, is expected to be recognized over a weighted-average period of 1.6 years. Total unrecognized pretax compensation cost related to RSUs and PSUs of $83 million at December 31, 2019, is expected to be recognized over a weighted average period of 2.0 years. The total fair value of RSUs and PSUs vested in the year ended December 31, 2019 was $37 million. The weighted average grant-date fair value of restricted stock units granted during 2019 was $72.67.

DuPont Omnibus Incentive Plan

The Company grants stock-based compensation awards to certain employees, directors, independent contractors and consultants in the form of stock incentive plans, which include stock options, RSUs and PSUs. The DuPont OIP has two subplans that have the same terms and conditions of the Historical Dow and Historical EID plans immediately prior to the Distributions. Awards previously granted under those plans that were nonvested will now vest in each subplan. All new awards will be granted by the OIP. Under the DuPont OIP, a maximum of 14 million shares of common stock may be awarded.

OIP 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. Stock option awards expire 10 years after the grant date. The plan allows retirement-eligible employees of the Company to retain any granted awards upon retirement provided the employee has rendered at least six months of service following the grant date.

The Company uses the Black-Scholes option pricing model to determine the fair value of stock option awards and the assumptions set forth in the table below. The weighted-average grant-date fair value of options granted for the year ended December 31, 2019. The weighted-average assumptions used to calculate total stock-based compensation are included in the following table:

OIP Weighted-Average Assumptions	2019
Dividend yield	1.8	%
Expected volatility	21.1	%
Risk-free interest rate	1.6	%
Expected life of stock options granted during period (years)	6.1

The Company determines the dividend yield by dividing the annualized dividend on DuPont's common stock by the option exercise price. A historical daily measurement of volatility (using DowDuPont stock information after the Merger date and a weighted average of Historical Dow and Historical EID prior to Merger date) is determined based on the expected life of the option granted. 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 DuPont's historical experience, adjusted for expected exercise patterns of in-the-money options.

The following table summarizes stock option activity for 2019 under the OIP:

OIP Stock Options	For the Year Ended December 31, 2019
	Number of Shares  (in thousands)		Weighted Average Exercise Price (per share)		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands)

1. No awards have vested under the OIP as of December 31, 2019.

F-67

The aggregate intrinsic values in the table above represent the total pretax intrinsic value (the difference between the closing stock price on the last trading day of 2019 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 year end.

OIP Restricted Stock Units and Performance Deferred Stock

The Company grants RSUs to certain employees that serially vested over a three-year period and, upon vesting, convert one-for-one to DuPont 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. 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 under a subplan of the DuPont OIP. Vesting for PSUs granted is based upon achieving certain adjusted operating EBITDA targets and certain return on invested capital ("ROIC") targets, weighted evenly between the metrics. Performance and payouts are determined independently for each metric. The actual award, delivered as DuPont common stock, can range from zero percent to two-hundred percent of the original grant. The weighted-average grant-date fair value of the PSUs is based upon the market price of the underlying common stock as of the grant date.

Nonvested awards of RSUs and PSUs are shown below.

OIP RSUs and PSUs	2019
	Number of Shares (in thousands)		Weighted Average Grant Date Fair Value (per share)
Nonvested at January 1, 2019	—		$	—
Granted	566		$	66.55
Vested	—		$	—
Forfeited	(5	)	$	66.06
Nonvested at December 31, 2019	561		$	66.56

Historical Dow Plans

Historical Dow granted stock-based compensation to employees and non-employee directors in the form of stock incentive plans, which include stock options, RSUs and restricted stock. Historical Dow also provided stock-based compensation in the form of PSUs and the Employee Stock Purchase Plan ("ESPP"), which grants eligible employees the right to purchase shares of Historical Dow Common Stock at a discounted price.

Historical Dow Valuation Methods and Assumptions

Historical Dow previously used a lattice-based option valuation model to estimate the fair value of stock options and used a Monte Carlo simulation for the market portion of PSU awards. Effective with the first quarter of 2018 grant, Historical Dow began using the Black-Scholes option valuation model to estimate the fair value of stock options. This valuation methodology was adopted as a result of the Merger to align valuation methodologies with Historical EID and better align with industry practice. Historical Dow used the Black-Scholes option valuation model for subscriptions to purchase shares under the ESPP. The weighted-average assumptions used to calculate total stock-based compensation are included in the following table:

Historical Dow Weighted-Average Assumptions 1	2018		2017
Dividend yield	2.13	%	3.01	%
Expected volatility	23.34	%	23.71	%
Risk-free interest rate	2.83	%	1.28	%
Expected life of stock options granted during period (years)	6.2		7.5
Life of Employee Stock Purchase Plan (months)	—		3

1. No awards were granted by the Company out of the Historical Dow plan during 2019.

The dividend yield assumption was equal to the dividend yield on the grant date, which reflected the most recent DowDuPont quarterly dividend payment of $0.38 per share in 2018 ($0.46 per share in 2017 on Historical Dow Common Stock). The expected volatility assumptions for the 2017 stock options and ESPP were based on an equal weighting of the historical daily volatility for the contractual term of the awards and current implied volatility from exchange-traded options. The expected volatility assumptions for the 2018 stock options were based on an equal weighting of the historical daily volatility for the expected term of the awards and current implied volatility from exchange-traded options. The expected volatility assumption for the market portion of the 2017 PSU awards were based on historical daily volatility for the term of the award. The risk-free interest rate was based on the weighted-average of U.S. Treasury strip rates over the contractual term of the 2017 options. The risk-free interest rate was based on the

F-68

U.S. Treasury strip rates over the expected life of the 2018 options. The expected life of stock options granted was based on an analysis of historical exercise patterns.

Historical Dow Stock Incentive Plan

Historical Dow previously granted equity awards under various plans (the "Prior Plans"). On February 9, 2012, Historical Dow's Board of Directors authorized The Dow Chemical Company 2012 Stock Incentive Plan (the "2012 Plan"), which was approved by stockholders at Historical Dow's annual meeting on May 10, 2012 ("Original Effective Date") and became effective on that date. On February 13, 2014, Historical Dow's Board of Directors adopted The Dow Chemical Company Amended and Restated 2012 Stock Incentive Plan (the "2012 Restated Plan"). The 2012 Restated Plan was approved by stockholders at Historical Dow's annual meeting on May 15, 2014, and became effective on that date. The Prior Plans were superseded by the 2012 Plan and the 2012 Restated Plan (collectively, the "2012 Plan"). Under the 2012 Plan, Historical Dow may grant options, RSUs, PSUs, restricted stock, stock appreciation rights and stock units to employees and non-employee directors until the tenth anniversary of the Original Effective Date, subject to an aggregate limit and annual individual limits. The terms of the grants are fixed at the grant date. Historical Dow's stock-based compensation programs were assumed by DowDuPont and continue in place with the ability to grant and issue DowDuPont common stock.

In connection with the Merger, on August 31, 2017 ("Conversion Date") all outstanding Historical Dow stock options and RSU awards were converted into stock options and RSU awards with respect to DowDuPont Common Stock. The stock options and RSU awards have the same terms and conditions under the applicable plans and award agreements prior to the Merger. All outstanding and nonvested PSU awards were converted into RSU awards with respect to DowDuPont Common Stock at the greater of the applicable performance target or the actual performance as of the effective time of the Merger. Changes in the fair value of liability instruments are recognized as compensation expense each quarter. Upon the adoption of the OIP, the 2012 Plan became an inactive sub plan of the OIP and no longer grants new awards. All previously granted awards still vest under the 2012 Plan with the same terms and conditions that were applicable to the awards immediately prior to the Distributions.

Historical Dow Stock Options

Historical Dow granted stock options to certain employees, subject to certain annual and individual limits, with terms of the grants fixed at the grant date. The exercise price of each stock option equals the market price of Historical Dow’s stock on the grant date. Options vest from one year to three years, and had a maximum term of 10 years.

The following table summarizes stock option activity for 2019:

Historical Dow Stock Options	2019

Total incremental pretax compensation expense resulting from the conversion of PSU awards into RSU awards was $25 million ($20 million was recognized in the second half of 2017 and $5 million to be recognized over the remaining service period). Approximately 5,000 employees were impacted by the conversion.

Historical Dow Performance Stock Units

Historical Dow granted performance stock units to certain employees. The grants vest when specified performance targets are attained, such as return on capital and relative total shareholder return, over a predetermined period, generally one year to three years. In November 2017, DowDuPont granted PSUs to senior leadership measured on the realization of cost savings in connection with cost synergy commitments, as well as the Company’s ability to complete the Intended Business Separations. Performance and payouts are determined independently for each metric. Compensation expense related to PSU awards is recognized over the lesser of the service or performance period. Changes in the fair value of liability instruments are recognized as compensation expense each quarter.

The following table shows the PSU awards granted:

Historical Dow PSU Awards		Target Shares Granted 1	Grant Date Fair Value 2

Historical Dow Restricted Stock

Under the 2012 Plan, Historical Dow had the option to grant shares (including options, stock appreciation rights, stock units and restricted stock) to non-employee directors over the 10-year duration of the program, subject to the plan's aggregate limit as well as annual individual limits. The restricted stock issued under this plan cannot be sold, assigned, pledged or otherwise transferred by the non-employee director, until retirement or termination of service to Historical Dow. The following table shows the restricted stock issued under this plan:

Historical Dow Employee Stock Purchase Plan

On February 9, 2012, Historical Dow's Board of Directors authorized The Dow Chemical Company 2012 Employee Stock Purchase Plan (the "2012 ESPP") which was approved by stockholders at Historical Dow’s annual meeting on May 10, 2012. When offered, most employees are eligible to purchase shares of common stock of Historical Dow valued at up to 10 percent of their annual base salary. The value is determined using the plan price multiplied by the number of shares subscribed to by the employee. The plan price of the stock is set at an amount equal to at least 85 percent of the fair market value (closing price) of the common stock on a date during the fourth quarter of the year prior to the offering, or the average fair market value (closing price) of the common stock over a period during the fourth quarter of the year prior to the offering, in each case, specified by Historical Dow's Executive Vice President of Human Resources. The last offering of Historical Dow's 2012 ESPP closed on July 15, 2017. The ESPP was not offered in 2019 or 2018 and no current offerings remain outstanding.

Historical EID Plans

Prior to the Merger, Historical EID provided share-based compensation to its employees through grants of stock options, RSUs and PSUs. Most of these awards have been granted annually in the first quarter of each calendar year. Subsequent to the Merger, DowDuPont assumed sponsorship of the equity incentive compensation plan of Historical EID.

F-71

Historical EID Equity Incentive Plan

Historical EID's Equity Incentive Plan ("Historical EID EIP"), as amended and restated effective August 31, 2017, provides for equity-based and cash incentive awards to certain employees, directors and consultants. Under the Historical EID EIP, the maximum number of shares reserved for the grant or settlement of awards was 110 million shares, provided that each share in excess of 30 million that was issued with respect to any award that was not an option or stock appreciation right be counted against the 110 million share limit as four and one-half shares. Historical EID satisfied stock option exercises and vesting of RSUs and PSUs with shares of DowDuPont Common Stock. Upon the adoption of the OIP, Historical EID EIP became an inactive sub plan of the OIP and no longer grants new awards. All previously granted awards still vest under the Historical EID EIP with the same terms and conditions that were applicable to the awards immediately prior to the Distributions.

Historical EID Stock Options

The exercise price of shares subject to option is equal to the market price of Historical EID's stock on the date of grant. When converted into the right to receive 1.282 shares of DowDuPont Common Stock, the exercise price was also adjusted by the 1.282 conversion factor. All options vest serially over a three-year period. Stock option awards granted between 2010 and 2015 expire seven years after the grant date and options granted between 2016 and 2018 expire ten years after the grant date. The plan allowed retirement-eligible employees of Historical EID to retain any granted awards upon retirement provided the employee has rendered at least six months of service following the grant date. The awards have the same terms and conditions as were applicable to such equity awards immediately prior to the Merger closing date.

Historical EID used the Black-Scholes option pricing model to determine the fair value of stock option awards and the assumptions set forth in the table below. The weighted-average grant-date fair value of options granted for the years ended December 31, 2019, December 31, 2018 and December 31, 2017 was $15.69, $15.46 and $28.56, respectively. The weighted-average assumptions used to calculate total stock-based compensation are included in the following table:

Historical EID Weighted-Average Assumptions	2019		2018		2017
Dividend yield	1.6	%	2.1	%	2.2	%
Expected volatility	19.8	%	23.3	%	23.59	%
Risk-free interest rate	2.4	%	2.8	%	2.1	%
Expected life of stock options granted during period (years)	6.1		6.2		7.2

Historical EID 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 (using DowDuPont stock information after the Merger date and a weighted average of Historical Dow and Historical EID prior to Merger date) is determined based on the expected life of the option granted. 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 Historical EID's historical experience, adjusted for expected exercise patterns of in-the-money options.

The following table summarizes stock option activity for 2019 under Historical EID's EIP:

Historical EID Stock Options	2019
	Number of Shares (in thousands)		Weighted Average Exercise Price (per share)		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands)

Historical EID RSUs and PSUs

Historical EID issued RSUs that serially vested over a three-year period and, upon vesting, convert one-for-one to DowDuPont 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 were also granted periodically to key senior management employees. These RSUs generally vested over periods ranging from three years to five 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 awards have the same terms and conditions as were applicable to such equity awards immediately prior to the Merger closing date.

Historical EID granted PSUs to senior leadership. Upon a change in control, Historical EID's EIP provisions required PSUs to be converted into RSUs based on the number of PSUs that would vest by assuming that target levels of performance are achieved. Service requirements for vesting in the RSUs replicate those inherent in the exchanged PSUs.

Vesting for PSUs granted in 2016 and for the period January 1 through August 31, 2017 is based upon total shareholder return ("TSR") relative to peer companies. Vesting for PSUs granted in 2015 is equally based upon change in operating net income relative to target and TSR relative to peer companies. Operating net income is net income attributable to Historical EID excluding income from discontinued operations after taxes, significant after-tax benefits (charges), and non-operating pension and other postretirement benefit costs. Performance and payouts are determined independently for each metric. The actual award, delivered as DowDuPont 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 for the period January 1 through August 31, 2017, subject to the TSR metric, was $91.56, and estimated using a Monte Carlo simulation. The weighted-average grant-date fair value of the PSUs, subject to the revenue metric, was based upon the market price of the underlying common stock as of the grant date.

In accordance with the DWDP Merger Agreement, PSUs converted to RSU awards based on an assessment of the underlying market conditions in the PSUs at the greater of target or actual performance levels as of the closing date. As the actual performance levels were not in excess of target as of the closing date, all PSUs converted to RSUs based on target and there was no incremental benefit from the DWDP Merger Agreement when compared with Historical EID’s EIP.

In November 2017, DowDuPont granted PSUs to senior leadership that vest partially based on the realization of cost savings in connection with cost synergy commitments, as well as DowDuPont’s ability to complete the Intended Business Separations. Performance and payouts are determined independently for each metric. The actual award, delivered in DowDuPont 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 November 2017 of $71.16 was based upon the market price of the underlying common stock as of the grant date. There were no PSUs granted in the years ended December 31, 2019 and December 31, 2018.

Nonvested awards of RSUs and PSUs are shown below.

2. Equity securities with a readily determinable fair value. Presented in accordance with ASU 2016-01. "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities."

3. Presented net of cash collateral where master netting arrangements allow.

At December 31, 2019, the Company had $417 million ($8,226 million at December 31, 2018) 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. At December 31, 2018, the Company had $29 million 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 1 year at the time of purchase. The Company’s investments in held-to-maturity securities are held at amortized cost, which approximates fair value. These 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, interest rate 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 derivatives or 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. 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	December 31, 2019		December 31, 2018

Derivatives not designated as hedging instruments:
Foreign currency contracts 1	$	26	$	2,057
Commodity contracts	$	11	$	9

F-74

Derivatives not Designated in Hedging Relationships

Foreign Currency Contracts

The Company routinely uses forward 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 certain foreign currency-denominated revenues so that gains and losses on the contracts offset changes in the USD value of the related foreign currency-denominated revenues.

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 soybeans, soybean oil and soybean meal.

Fair Value of Derivative Instruments

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:

Fair Value of Derivative Instruments at December 31, 2019
In millions	Balance Sheet Classification	Gross		Counterparty and Cash Collateral Netting 1			Net Amounts Included in the Consolidated Balance Sheet

1. Counterparty and cash collateral amounts represent the estimated net settlement amount when applying netting and set-off rights included in master netting arrangements between the Company and its counterparties and the payable or receivable for cash collateral held or placed with the same counterparty. The Company held cash collateral of $20 million as of December 31, 2018.

F-75

Effect of Derivative Instruments

Foreign currency derivatives not designated as hedges are used to offset foreign exchange gains or losses resulting from the underlying exposures of foreign currency-denominated assets and liabilities. The amount charged on a pretax basis related to foreign currency derivatives not designated as a hedge, which was included in “Sundry income (expense) - net” in the Consolidated Statements of Operations, was a loss of $62 million for the year ended December 31, 2019 ($94 million gain for the year ended December 31, 2018 and $91 million gain for the year ended December 31, 2017). The income statement effects of other derivatives were immaterial.

Reclassification from AOCL

The Company does not expect to reclassify gains related to foreign currency contracts from AOCL to income within the next 12 months.

NOTE 23 - FAIR VALUE MEASUREMENTS

Fair Value Measurements on a Recurring Basis

The following tables summarize the basis used to measure certain assets and liabilities at fair value on a recurring basis:

2. Primarily time deposits with maturities of greater than three months at time of acquisition.

3. See Note 22 for the classification of derivatives in the Consolidated Balance Sheets

4. See Note 22 for information on fair value measurements of long-term debt.

F-76

The Company has equity securities of $1 million and $2 million as of December 31, 2019 and December 31, 2018, respectively, classified as level 1 measurements. The Company’s investments in equity securities are included in “Other investments” in the Consolidated Balance Sheets.

For 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 assets and liabilities 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, or by using observable market data points of similar, more liquid securities to imply the price. For time deposits classified as held-to-maturity investments and reported at amortized cost, fair value is based on an observable interest rate for similar securities. 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. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance/quality checks.

For all other assets and liabilities for which observable inputs are used, fair value is derived through the use of fair value models, such as a discounted cash flow model or other standard pricing models.

There were no transfers between Levels 1 and 2 during the year ended December 31, 2019 and December 31, 2018.

Fair Value Measurements on a Nonrecurring Basis

The following table summarizes the basis used to measure certain assets at fair value on a nonrecurring basis:

Basis of Fair Value Measurements on a Nonrecurring Basis	Significant Other Unobservable Inputs (Level 3)		Total Losses

2019 Fair Value Measurements on a Nonrecurring Basis

During the second quarter of 2019, the Company recorded goodwill impairment charges related to the Nutrition & Biosciences

and the Non-Core segments. See Note 14 for further discussion of these fair value measurements.

The Internal SP Distribution served as a triggering event to assess equity method investments for impairment. The Company recorded an other-than-temporary impairment, classified as Level 3 measurements, on an equity method investment during the second quarter of 2019. The impairment charge of $63 million was recorded in "Restructuring and asset related charges - net" in the Consolidated Statements of Operations. See Note 6 for further discussion of these fair value measurements.

2018 & 2017 Fair Value Measurements on a Nonrecurring Basis

The Company has or will shut down a number of manufacturing, R&D, other non-manufacturing facilities and corporate facilities around the world as part of its restructuring programs. Certain inventory, corporate facilities and manufacturing facilities and related assets, were written down to zero. The related charges totaled $32 million and $177 million for the year ended December 31, 2018 and 2017, respectively, and were included in "Restructuring and asset related charges - net" in the Consolidated Statements of Operations. See Note 6 for additional information on the Company's restructuring activities.

NOTE 24 - SEGMENTS AND GEOGRAPHIC REGIONS

The new segments are aligned with the market verticals they serve, while maintaining integration and innovation strengths within strategic value chains. DuPont is comprised of five operating segments: Electronics & Imaging; Nutrition & Biosciences; Safety & Construction; Transportation & Industrial; and Non-Core. Corporate contains the reconciliation between the totals for the reportable segments and the Company’s totals. The above reflects the following changes:

Effective June 1, 2019, DuPont changed its management and reporting structure resulting in the creation of a new Non-Core segment ("Second Quarter Segment Realignment").

• The Second Quarter Segment Realignment resulted in the following being realigned to Non-Core:

◦ Photovoltaic and Advanced Materials business unit (including the HSC Group joint ventures: DC HSC Holdings LLC and Hemlock Semiconductor L.L.C) from the Electronics & Imaging segment;

◦ Biomaterials and Clean Technologies business units from the Nutrition & Biosciences segment;

◦ DuPont Teijin Films joint venture from the Transportation & Industrial (formerly known as Transportation & Advanced Polymers) segment; and

◦ Sustainable Solutions business unit from the Safety & Construction segment.

•In addition, the following changes have occurred:

◦ Consolidation of the Nutrition & Health business with the Industrial Biosciences business within the Nutrition & Biosciences reportable segment. Previously, Nutrition & Health and Industrial Biosciences were separate operating segments which did not meet the quantitative thresholds.

◦ Pre-commercial activities related to the Biomaterials business unit was realigned from Corporate to Non-Core, with the remaining pre-commercial activities realigned to the Nutrition & Biosciences segment.

Effective October 1, 2019, Electronics & Imaging realigned its product lines as Image Solutions, Interconnect Solutions and Semiconductor Technologies.

These reporting changes have been retrospectively reflected in the segment results for all periods presented.

Major products by segment include: Electronics & Imaging (printing and packaging materials, photopolymers and electronic materials); Nutrition & Biosciences (probiotics, cultures, emulsifiers, texturants, natural sweeteners and soy-based food ingredients, enzymes, bio-based materials, cellulosics and process technologies); Transportation & Industrial (engineering resins, adhesives, silicones, lubricants and parts); Safety and Construction (nonwovens, aramids, construction materials, water filtration and purification resins, elements and membranes) and Non-Core (specialty biotechnology materials, alkylation technology, sulfuric acid technology, hydroprocessing technology, polyester films, metallization pastes, polyvinyl fluoromaterials, silicone encapsulants and adhesives, polycrystalline silicon, and sustainable materials and services.) The Company operates globally in substantially all of its product lines. Transfers of products between operating segments are generally valued at cost.

The Company's measure of profit/loss for segment reporting purposes is pro forma Operating EBITDA as this is the manner in which the Company's chief operating decision maker ("CODM") assessed performance and allocates resources. The Company defines pro forma Operating EBITDA as pro forma earnings (i.e. pro forma "Income (loss) from continuing operations before income taxes") before interest, depreciation, amortization, non-operating pension / other post employment benefits (“OPEB”) / charges, and foreign exchange gains/losses, excluding the impact of costs historically allocated to the materials science and agriculture businesses that did not meet the criteria to be recorded as discontinued operations and adjusted for significant items. Reconciliations of these measures are provided on the following pages.

Pro forma adjustments were determined in accordance with Article 11 of Regulation S-X. Pro forma financial information is based on the Consolidated Financial Statements of DuPont, adjusted to give effect to the impact of certain items directly attributable to the Merger, the Distributions, and the Term Loan Facilities, the 2018 Senior Notes and the Funding CP Issuance (together, the "Financings"), including the use of proceeds from such Financings (collectively the "Transactions"). The historical consolidated financial information has been adjusted to give effect to pro forma events that are (1) directly attributable to the Transactions, (2) factually supportable and (3) with respect to the statements of operations, expected to have a continuing impact on the results. Events that are not expected to have a continuing impact on the combined results are excluded from the pro forma adjustments. Those pro forma adjustments include the impact of various supply agreements entered into in connection with the Dow Distribution ("supply agreements") and are adjustments to "Cost of sales". The impact of these supply agreements are reflected in pro forma Operating EBITDA for the periods noted above as they are included in the measure of profit/loss reviewed by the CODM in order to show meaningful comparability among periods while assessing performance and making resource allocation decisions.

SEGMENTS AND GEOGRAPHIC REGIONS

Segment Reporting [Abstract]

SEGMENTS AND GEOGRAPHIC REGIONS

SEGMENTS AND GEOGRAPHIC REGIONS

The new segments are aligned with the market verticals they serve, while maintaining integration and innovation strengths within strategic value chains. DuPont is comprised of five operating segments: Electronics & Imaging; Nutrition & Biosciences; Safety & Construction; Transportation & Industrial; and Non-Core. Corporate contains the reconciliation between the totals for the reportable segments and the Company’s totals. The above reflects the following changes:

Effective June 1, 2019, DuPont changed its management and reporting structure resulting in the creation of a new Non-Core segment ("Second Quarter Segment Realignment").

• The Second Quarter Segment Realignment resulted in the following being realigned to Non-Core:

◦ Photovoltaic and Advanced Materials business unit (including the HSC Group joint ventures: DC HSC Holdings LLC and Hemlock Semiconductor L.L.C) from the Electronics & Imaging segment;

◦ Biomaterials and Clean Technologies business units from the Nutrition & Biosciences segment;

◦ DuPont Teijin Films joint venture from the Transportation & Industrial (formerly known as Transportation & Advanced Polymers) segment; and

◦ Sustainable Solutions business unit from the Safety & Construction segment.

•In addition, the following changes have occurred:

◦ Consolidation of the Nutrition & Health business with the Industrial Biosciences business within the Nutrition & Biosciences reportable segment. Previously, Nutrition & Health and Industrial Biosciences were separate operating segments which did not meet the quantitative thresholds.

◦ Pre-commercial activities related to the Biomaterials business unit was realigned from Corporate to Non-Core, with the remaining pre-commercial activities realigned to the Nutrition & Biosciences segment.

Effective October 1, 2019, Electronics & Imaging realigned its product lines as Image Solutions, Interconnect Solutions and Semiconductor Technologies.

These reporting changes have been retrospectively reflected in the segment results for all periods presented.

Major products by segment include: Electronics & Imaging (printing and packaging materials, photopolymers and electronic materials); Nutrition & Biosciences (probiotics, cultures, emulsifiers, texturants, natural sweeteners and soy-based food ingredients, enzymes, bio-based materials, cellulosics and process technologies); Transportation & Industrial (engineering resins, adhesives, silicones, lubricants and parts); Safety and Construction (nonwovens, aramids, construction materials, water filtration and purification resins, elements and membranes) and Non-Core (specialty biotechnology materials, alkylation technology, sulfuric acid technology, hydroprocessing technology, polyester films, metallization pastes, polyvinyl fluoromaterials, silicone encapsulants and adhesives, polycrystalline silicon, and sustainable materials and services.) The Company operates globally in substantially all of its product lines. Transfers of products between operating segments are generally valued at cost.

The Company's measure of profit/loss for segment reporting purposes is pro forma Operating EBITDA as this is the manner in which the Company's chief operating decision maker ("CODM") assessed performance and allocates resources. The Company defines pro forma Operating EBITDA as pro forma earnings (i.e. pro forma "Income (loss) from continuing operations before income taxes") before interest, depreciation, amortization, non-operating pension / other post employment benefits (“OPEB”) / charges, and foreign exchange gains/losses, excluding the impact of costs historically allocated to the materials science and agriculture businesses that did not meet the criteria to be recorded as discontinued operations and adjusted for significant items. Reconciliations of these measures are provided on the following pages.

Pro forma adjustments were determined in accordance with Article 11 of Regulation S-X. Pro forma financial information is based on the Consolidated Financial Statements of DuPont, adjusted to give effect to the impact of certain items directly attributable to the Merger, the Distributions, and the Term Loan Facilities, the 2018 Senior Notes and the Funding CP Issuance (together, the "Financings"), including the use of proceeds from such Financings (collectively the "Transactions"). The historical consolidated financial information has been adjusted to give effect to pro forma events that are (1) directly attributable to the Transactions, (2) factually supportable and (3) with respect to the statements of operations, expected to have a continuing impact on the results. Events that are not expected to have a continuing impact on the combined results are excluded from the pro forma adjustments. Those pro forma adjustments include the impact of various supply agreements entered into in connection with the Dow Distribution ("supply agreements") and are adjustments to "Cost of sales". The impact of these supply agreements are reflected in pro forma Operating EBITDA for the periods noted above as they are included in the measure of profit/loss reviewed by the CODM in order to show meaningful comparability among periods while assessing performance and making resource allocation decisions.

Sales are attributed to geographic regions based on customer location; long-lived assets are attributed to geographic regions based on asset location.

RECENT ACCOUNTING GUIDANCE (Policies)

12 Months Ended

Dec. 31, 2019

Recent Accounting Guidance [Abstract]

New Accounting Pronouncements, Policy

Recently Adopted Accounting Guidance

In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, Leases (Topic 842), and associated ASUs related to Topic 842, which requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. The new guidance requires that a lessee recognize assets and liabilities for leases, and recognition, presentation and measurement in the financial statements depends on whether the lease is classified as a finance or operating lease. In addition, the new guidance requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. Lessor accounting remains largely unchanged from previous U.S. GAAP but does contain some targeted improvements to align with the new revenue recognition guidance, referred to as "Topic 606," issued in 2014.

The Company adopted the new standard in the first quarter of 2019, which allows for a modified retrospective transition approach, applying the new standard to all leases existing at the date of initial adoption. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statement as its date of initial application. The Company has elected to apply the transition requirements at the January 1, 2019 effective date rather than at the beginning of the earliest comparative period presented. This approach allows for a cumulative effect adjustment in the period of adoption, and prior periods are not restated and continue to be reported in accordance with historic accounting under ASC 840 (Leases). In addition, the Company has elected the package of practical expedients permitted under the transition guidance within the new standard which does not require reassessment of prior conclusions related to contracts containing a lease, lease classification and initial direct lease costs. As an accounting policy election, the Company chose to not apply the standard to certain existing land easements, excluded short-term leases (term of 12 months or less) from the balance sheet and accounts for nonlease and lease components in a contract as a single component for all asset classes. The following table summarizes the impact of adoption to the Consolidated Balance Sheet:

1. The as reported December 31, 2018 information has been updated to reflect the impact of the reverse stock split and the change in accounting policy discussed in Note 1.

2. The net impact to retained earnings was primarily a result of the recognition of a deferred gain associated with a prior sale-leaseback transaction.

The adoption of the new guidance did not have a material impact on the Company's Consolidated Statement of Operations and had no impact on the Consolidated Statement of Cash Flows.

In August 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Topic 715-20), Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. This amendment modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans by removing and adding certain disclosures for these plans. The eliminated disclosures include the amounts in "Accumulated Other Comprehensive Income" expected to be recognized in net periodic benefit costs over the next fiscal year and the effects of a one-percentage-point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for postretirement health care benefits. New disclosures include the interest crediting rates for cash balance plans, and an explanation of significant gains and losses related to changes in benefit obligations. The new standard is effective for fiscal years beginning after December 15, 2020, and must be applied retrospectively for all periods presented. Early adoption is permitted. The Company early adopted the new guidance in the fourth quarter of 2019, and adoption did not have a material impact on the Consolidated Financial Statements.

Accounting Guidance Issued But Not Adopted at December 31, 2019

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and associated ASUs related to Topic 326. The new guidance introduces the current expected credit loss (“CECL”) model, which requires organizations to record an allowance for credit losses for certain financial instruments and financial assets, including trade receivables, based on expected losses rather than incurred losses. Under this update, on initial recognition and at each reporting period, an entity will be required to recognize an allowance that reflects the entity’s current estimate of credit losses expected to be incurred over the life of the financial instrument. This update will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, and early adoption is permitted.

The Company has a cross-functional team in place to evaluate and implement the new guidance and the Company has substantially completed the implementation of the standard to be in compliance with accounting and reporting requirements. The team continues to review existing financial instruments and update business processes and controls related to the new guidance for credit losses. Collectively, these activities are expected to facilitate the Company's ability to meet the new accounting and disclosure requirements upon adoption in the first quarter of 2020.

The ASU requires a modified retrospective transition approach, applying the new standards cumulative-effect adjustment as of the beginning of the first reporting period in which the guidance is effective. Therefore, this cumulative-effect will be reflected as of January 1, 2020 and prior periods will not be restated. The Company is finalizing the evaluation of the January 1, 2020 impact and estimates that the impact to the Company’s Consolidated Balance Sheet will not be material. The impact to the Company's Consolidated Statements of Operations and Consolidated Statement of Cash Flows is expected not to be material.

Effective June 1, 2019, after the Corteva Distribution, the Company changed its method of valuing certain inventories of the specialty products business from the LIFO method to the average cost method. Management believes that the change in accounting is preferable as it results in a consistent method to value inventory across all regions of the business, it improves comparability with industry peers, and it more closely resembles the physical flow of inventory. The effects of the change in accounting principle from LIFO to average cost have been retrospectively applied to all periods presented. This change resulted in an increase to "(Accumulated Deficit) Retained Earnings" of $21 million as of January 1, 2017.  

In addition, certain financial statement line items in the Company’s Consolidated Statement of Operations for the year ended December 31, 2017 were adjusted as follows:

1. The year ended December 31, 2019 includes income of $92 million, related to a sale of assets within the Electronics & Imaging segment and as well as a gain of $28 million related to the sale of the Sustainable Solutions business unit within the Non-Core segment.

2. Includes a $50 million foreign exchange loss for the year ended December 31, 2018 related to adjustments to Historical EID's foreign currency exchange contracts as a result of U.S. tax reform.

3. Miscellaneous income and expenses - net, for the year ended December 31, 2019 includes a $48 million charge reflecting a reduction in gross proceeds from lower withholding taxes related to a prior year legal settlement and a $74 million charge related to tax indemnifications, primarily associated with an adjustment to a one-time transition tax liability required by the Tax Cuts and Jobs Act of 2017, which were recorded in accordance with the Amended and Restated Tax Matters Agreement. These charges were offset by various indemnification and lease income amounts. The miscellaneous income for the year ended 2018 primarily relates to legal settlements.

Cash, Cash Equivalents and Restricted Cash

The Company is required to set aside funds for various activities that arise in the normal course of business. These funds typically have legal restrictions associated with them and are deposited in an escrow account or held in a separately identifiable account by the Company. Historical EID entered into a trust agreement in 2013 (as amended and restated in 2017), establishing and requiring Historical EID to fund a trust (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. After the Corteva Distribution, the Trust assets related to Corteva employees were transferred to a new trust for Corteva (the "Corteva Trust"). As a result, the Trust currently held by DuPont relates to funding obligations to DuPont employees. At December 31, 2019, the Company had restricted cash of $37 million ($43 million at December 31, 2018) included in "Other current assets" in the Consolidated Balance Sheets which was completely attributed to the Trust.

Accrued and Other Current Liabilities

"Accrued and other current liabilities" in the Consolidated Balance Sheets were $1,342 million at December 31, 2019 and $1,129 million at December 31, 2018. Accrued payroll, which is a component of "Accrued and other current liabilities," was $479 million at December 31, 2019 and $506 million at December 31, 2018. No other components of "Accrued and other current liabilities" were more than five percent of total current liabilities.

BUSINESS COMBINATION [Abstract]

BUSINESS COMBINATIONS

Merger of Equals of Historical Dow and Historical EID

At the effective time of the Merger, each share of common stock, par value $2.50 per share, of Historical Dow ("Historical Dow Common Stock") (excluding any shares of Historical Dow Common Stock that were held in treasury immediately prior to the effective time of the Merger, which were automatically canceled and retired for no consideration) was converted into the right to receive one fully paid and non-assessable share of common stock, par value $0.01 per share, of DowDuPont ("DowDuPont Common Stock"). Upon completion of the Merger, (i) each share of common stock, par value $0.30 per share, of Historical EID (“Historical EID Common Stock”) (excluding any shares of Historical EID Common Stock that were held in treasury immediately prior to the effective time of the Merger, which were automatically canceled and retired for no consideration) was converted into the right to receive 1.2820 fully paid and non-assessable shares of DowDuPont Common Stock, in addition to cash in lieu of any fractional shares of DowDuPont Common Stock, and (ii) each share of Historical EID Preferred Stock $4.50 Series and Historical EID Preferred Stock $3.50 Series (collectively, the “Historical EID Preferred Stock”) issued and outstanding immediately prior to the effective time of the Merger remains issued and outstanding and was unaffected by the Merger. The Historical EID Preferred Stock was separated from the Company at the time of the Corteva Distribution.

As provided in the DWDP Merger Agreement, at the effective time of the Merger, Historical Dow stock options and other equity awards were generally automatically converted into stock options and equity awards with respect to DowDuPont Common Stock and Historical EID stock options and other equity awards, after giving effect to the exchange ratio, were converted into stock options and equity awards with respect to DowDuPont Common Stock, and otherwise generally on the same terms and conditions under the applicable plans and award agreements immediately prior to the effective time of the Merger. See Notes 18 and 21 for additional information.

Allocation of Purchase Price

Based on an evaluation of the provisions of Accounting Standards Codification ("ASC") 805, "Business Combinations" ("ASC 805"), Historical Dow was determined to be the accounting acquirer in the Merger. DowDuPont applied the acquisition method of accounting with respect to the assets and liabilities of Historical EID, which were measured at fair value as of the date of the Merger.

Historical EID's assets and liabilities were measured at estimated fair values at August 31, 2017, primarily using Level 3 inputs. Estimates of fair value represent management's best estimate and require a complex series of judgments about future events and uncertainties. Third-party valuation specialists were engaged to assist in the valuation of these assets and liabilities.

At the time of the Merger, the total fair value of consideration transferred was $74,680 million. Total consideration is comprised of the equity value of the DowDuPont shares at August 31, 2017, that were issued in exchange for Historical EID shares, the cash value for fractional shares, and the portion of Historical EID's share awards and share options earned at August 31, 2017. Share awards and share options converted to DowDuPont equity instruments, but not vested, were $144 million at August 31, 2017, which was expensed over the remaining future vesting period.

The following table provides "Net sales" and "Loss from continuing operations before income taxes" related to Historical EID's specialty products business which are included in the Company's continuing operations results for the period September 1 through December 31, 2017. Included in the results from Historical EID was $92 million of "Restructuring and asset related charges - net", $1,320 million that was recognized in "Cost of sales" as inventory was sold related to the fair value step-up of inventories and $220 million of "Integration and separation costs" in the Consolidated Statement of Operations.

In millions	December 31, 2017
Net sales	$	4,911
Loss from continuing operations before income taxes	$	1,155

Unaudited Supplemental Pro Forma Information

The unaudited pro forma results presented below were prepared pursuant to the requirements of ASC 805 and give effect to the Merger as if it had been consummated on January 1, 2016. The pro forma results do not necessarily represent what the revenue or results of operations would have been had the Merger been completed on January 1, 2016, are not intended to be a projection of future operating results and do not reflect synergies that might be achieved by the Company. In addition, amounts below have been revised to give effect to the discontinued operations of Dow and Corteva.

The pro forma results include adjustments for the purchase accounting impact (including, but not limited to, depreciation and amortization associated with the acquired tangible and intangible assets, amortization of the fair value adjustment to investment in nonconsolidated affiliates, and reduction of interest expense related to the fair value adjustment to long-term debt, along with the related tax impacts), the alignment of accounting policies, and the elimination of transactions between Historical Dow and Historical EID. Costs incurred to prepare for the Merger have been excluded from the 2017 pro forma results presented below based on an assumption they were incurred in 2016. The costs incurred related to integration and to prepare for the Distributions are reflected in the pro forma results. In addition, the Company incurred an after-tax charge of $1,038 million in 2017 related to the fair value step-up of inventories acquired and sold. The 2017 pro forma results were adjusted to exclude this charge based on an assumption the charge was incurred in 2016.

The unaudited pro forma results for all periods presented below exclude the results of operations of the businesses reflected as discontinued operations.

DuPont Pro Forma Results of Operations	2017

Net sales	$	21,000
Income from continuing operations, net of tax	$	1,772
Earnings per common share from continuing operations - basic	$	2.23
Earnings per common share from continuing operations - diluted	$	2.21

Acquisition of H&N Business

On March 31, 2017, Historical EID entered into a definitive agreement (the "FMC Transaction Agreement") with FMC Corporation ("FMC") for FMC to acquire the assets related to Historical EID's crop protection business and research and development ("R&D") organization (the "Divested Ag Business") that Historical EID was required to divest in order to obtain European Commission ("EC") approval of the Merger Transaction. In addition, under the FMC Transaction Agreement, Historical EID agreed to acquire certain assets relating to FMC’s Health and Nutrition segment, excluding its Omega-3 products (the "H&N Business") (the sale of the Divested Ag Business and acquisition of the H&N Business referred to collectively as the "FMC Transactions"). See Note 4 for further discussion of the Divested Ag Business.

On November 1, 2017, Historical EID completed the FMC Transactions through the acquisition of the H&N Business and the divestiture of the Divested Ag Business. The acquisition was integrated into Nutrition & Biosciences to enhance the Company’s position as a leading provider of sustainable, bio-based food ingredients and allow for expanded capabilities in the pharma excipients space. Historical EID accounted for the acquisition in accordance with ASC 805, which requires the assets acquired and liabilities assumed to be recognized on the balance sheet at their fair values as of the acquisition date. Total consideration of the H&N Business was $1,970 million.

The Company evaluated the disclosure requirements under ASC 805 and determined the H&N Business was not considered a material business combination for purposes of disclosing the revenue and earnings of the H&N Business since the date of acquisition or supplemental pro forma information.

2019 Acquisitions

During the fourth quarter of 2019, DuPont completed acquisitions of the following, all within the Safety & Construction segment:

• inge GmbH, an ultrafiltration membrane business from BASF,

• Memcor, the ultrafiltration and membrane bioreactor technologies division from Evoqua Water Technologies Corp.,

• OxyMem Limited, a company that develops and produces Membrane Aerated Biofilm Reactor technology.

The aggregate purchase price of the above acquisitions was approximately $175 million and was primarily allocated to goodwill, other intangibles and property, plant and equipment.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Dec. 31, 2019

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation and Basis of Presentation

The accompanying Consolidated Financial Statements of DuPont de Nemours, Inc. ("DuPont” or “the Company”) were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The significant accounting policies described below, together with the other notes that follow, are an integral part of the Consolidated Financial Statements.

Effective August 31, 2017, pursuant to the merger of equals transaction contemplated by the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017 ("DWDP Merger Agreement"), The Dow Chemical Company ("Historical Dow") and E. I. du Pont de Nemours and Company ("Historical EID") each merged with subsidiaries of DowDuPont Inc. ("DowDuPont") and, as a result, Historical Dow and Historical EID became subsidiaries of DowDuPont (the "Merger"). Prior to the Merger, DowDuPont did not conduct any business activities other than those required for its formation and matters contemplated by the DWDP Merger Agreement. For purposes of DowDuPont's financial statement presentation, Historical Dow was determined to be the accounting acquirer in the Merger and Historical EID's assets and liabilities are reflected at fair value as of the Merger Effectiveness Time. The financial statements of Historical Dow for periods prior to the Merger are considered to be the historical financial statements of the Company.

Except as otherwise indicated by the context, the term "Historical Dow" includes Historical Dow and its consolidated subsidiaries, "Historical EID" includes Historical EID and its consolidated subsidiaries, and "Dow Silicones" means Dow Silicones Corporation, a wholly owned subsidiary of Historical Dow.

Distributions

Effective as of 5:00 p.m. on April 1, 2019, the Company completed the separation of its materials science business into a separate and independent public company by way of a distribution of Dow Inc. (“Dow”) through a pro rata dividend in-kind of all of the then-issued and outstanding shares of Dow’s common stock (the “Dow Common Stock”), to holders of the Company’s common stock (the “DowDuPont common stock”), as of the close of business on March 21, 2019 (the “Dow Distribution”).

Effective as of 12:01 a.m. on June 1, 2019, the Company completed the separation of its agriculture business into a separate and independent public company by way of a distribution of Corteva, Inc. (“Corteva”) through a pro rata dividend in-kind of all of the then-issued and outstanding shares of Corteva’s common stock (the “Corteva Common Stock”), to holders of the Company’s common stock as of the close of business on May 24, 2019 (the “Corteva Distribution” and, together with the Dow Distribution, the “Distributions”).

Following the Corteva Distribution, DuPont holds the specialty products business as continuing operations. On June 1, 2019, DowDuPont changed its registered name from "DowDuPont Inc." to "DuPont de Nemours, Inc." doing business as "DuPont." Beginning on June 3, 2019, the Company's common stock is traded on the NYSE under the ticker symbol "DD".

These Consolidated Financial Statements present the financial position of DuPont as of December 31, 2019 and 2018 and the results of operations of DuPont for the years ended December 31, 2019, 2018 and 2017 giving effect to the Distributions, with the historical financial results of Dow and Corteva reflected as discontinued operations. The sum of the individual earnings per share amounts from continuing operations and discontinued operations may not equal the total company earnings per share amounts due to rounding. The cash flows and comprehensive income related to Dow and Corteva have not been segregated and are included in the Consolidated Statements of Cash Flows and Consolidated Statements of Comprehensive Income, respectively, for all periods presented. Unless otherwise indicated, amounts or activity of Dow and Corteva are consistently included or excluded from the Notes to the Consolidated Financial Statements based on the respective financial statement line item.

On December 15, 2019, the Company entered into definitive agreements to separate and combine the Nutrition & Biosciences business segment (the "N&B Business") with International Flavors & Fragrances Inc. ("IFF") in a tax-efficient Reverse Morris Trust transaction, (the "Proposed N&B Transaction"). The transaction is expected to close by the end of the first quarter of 2021, subject to approval by IFF shareholders and other customary closing conditions, including regulatory approvals and receipt by DuPont of an opinion of tax counsel. The financial results of the N&B Business are included in continuing operations for the periods presented.

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, 2019 and 2018, 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.

Reverse Stock Split

On June 1, 2019, immediately following the Corteva Distribution, the Company completed a 1-for-3 reverse stock split of DuPont's outstanding common stock (the "Reverse Stock Split") and as a result, DuPont common stockholders now hold one share of common stock of DuPont for every three shares held prior to the Reverse Stock Split. The authorized number of shares of common stock was reduced from 5,000,000,000 shares to 1,666,666,667 shares, par value remained $0.01 per share. Stockholders entitled to fractional shares as a result of the Reverse Stock Split received a cash payment in lieu of receiving fractional shares. All share and share-related information presented in these Consolidated Financial Statements have been retroactively adjusted in all periods presented to reflect the decreased number of shares resulting from the Reverse Stock Split. The retroactive adjustments resulted in the reclassification of $16 million from "Common stock" to "Additional paid-in capital" in the Consolidated Balance Sheets for all periods presented.

Leases

The Company adopted the Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)" in the first quarter of 2019. 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 "Deferred charges and other assets" on the Consolidated Balance Sheets. Operating lease liabilities are included in "Accrued and other current liabilities" and "Other noncurrent obligations" on the Consolidated Balance Sheets. Finance lease ROU assets are included in "Property, plant and equipment - net" and the corresponding lease liabilities are included in "Short-term borrowings and finance lease obligations" and "Long-term debt" on the Consolidated Balance Sheets.  

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, and lease expense is recognized 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. Additionally, for certain equipment leases, the portfolio approach is applied to account for the operating lease ROU assets and lease liabilities. In the Consolidated Statements of Operations, lease expense for operating lease payments 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 Notes 2 and 17 for additional information regarding the Company's leases.

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

Restricted cash represents trust assets of $37 million and $43 million as of December 31, 2019 and 2018, respectively, and is included within "Other current assets" on the Consolidated Balance Sheets. See Note 7 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.

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 local 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 (local 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 the year, 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 the local currency is the functional currency, assets and liabilities denominated in local 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 loss in equity. Assets and liabilities denominated in other than the local currency are re-measured into the local 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 the period.

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.

Prior to the Corteva Distribution, the Company recorded inventory under the last-in, first-out ("LIFO"), first-in, first-out ("FIFO") and average cost methods. During the second quarter of 2019, effective after the Corteva Distribution, DuPont elected to change the method of accounting for inventories of the specialty products business recorded under the LIFO method to the average cost method. The effects of the change in accounting principle have been retrospectively applied to all prior periods presented. See Note 11 for more information regarding the change in inventory accounting method.

Approximately 17 percent and 83 percent of the Company's inventories were accounted for under the FIFO and the average cost methods, respectively, at both December 31, 2019 and December 31, 2018. Inventories accounted for under the FIFO method are primarily comprised of products with shorter shelf lives such as certain food-ingredients and enzymes. The Company establishes allowances for obsolescence of 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 annually during the fourth quarter, 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.

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. The Company determines fair values for each of the reporting units using a combination of the income approach and/or 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. Under the market approach, the Company selected peer sets based on close competitors and reviewed the EBIT/EBITDA multiples to determine the fair value. See Note 14 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's fair value methodology is primarily based on discounted cash flow techniques.

Definite-lived intangible assets are amortized over their estimated useful lives, generally on a straight-line basis for periods ranging primarily from 1 to 26 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.

Impairment and Disposals 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 or loss is reported in "Accumulated other comprehensive loss" ("AOCL") until it is cleared to earnings during the same period in which the hedged item affects earnings.

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 AOCL generally remains in AOCL 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.

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 5 for additional information on revenue recognition.

Cost of Sales

Cost of sales 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 and other operational expenses. No amortization of intangibles is included within costs of sales.

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, enhancement of existing products and regulatory approval of new and existing products.

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, the Distributions, and beginning in the fourth quarter of 2019, the intended separation of the Nutrition & Biosciences business. 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

Accruals for legal matters 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.

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 Company accrues for other tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated. The current portion of uncertain income tax positions is included in income taxes payable and the long-term portion is included in other noncurrent obligations in the Consolidated Balance Sheets.

Senior Notes

In contemplation of the Distributions and in preparation to achieve the intended credit profiles of Corteva, Dow and DuPont, in the fourth quarter of 2018, the Company consummated a public underwritten offer of eight series of senior unsecured notes (the "2018 Senior Notes") in an aggregate principal amount of $12.7 billion. The 2018 Senior Notes are a senior unsecured obligation of the Company and will rank equally with the Company's future senior unsecured debt outstanding from time to time. On November 1, 2018, the Company announced a $3 billion share buyback program, which expired on March 31, 2019. In the first quarter of 2019, proceeds from the 2018 Senior Notes were used to purchase $1.6 billion of shares. As a result, the share buyback program was complete at March 31, 2019.

Term Loan and Revolving Credit Facilities

In May 2019, the Company fully drew the two term loan facilities it entered into in the fourth quarter of 2018 (the “Term Loan Facilities”) in the aggregate principal amount of $3,000 million. In May 2019, the Company amended its $3,000 million five-year revolving credit facility (the “Five-Year Revolver”) entered into in the fourth quarter of 2018 to become effective and available as of the amendment. In addition, in June 2019, the Company entered into a $750 million, 364-day revolving credit facility (the "364-day Revolving Credit Facility"). The Company intends to renew the 364-Day Revolving Credit Facility on or prior to expiration.

Uncommitted Credit Facilities and Outstanding Letters of Credit

Unused bank credit lines on uncommitted credit facilities were $566 million at December 31, 2019. 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, 2019. These letters of credit support commitments made in the ordinary course of business.

Debt Covenants and Default Provisions

The Company's indenture covenants include customary limitations on liens, sale and leaseback transactions, and mergers and consolidations, subject to certain limitations. The 2018 Senior Notes also contain customary default provisions. The Term Loan

Facilities, the Five-Year Revolving Credit Facility and the 364-Day Revolving Credit Facility contain a financial covenant requiring that the ratio of Total Indebtedness to Total Capitalization for the Company and its consolidated subsidiaries not exceed 0.60. At December 31, 2019, the Company was in compliance with this financial covenant. There were no material changes to the debt covenants and default provisions at December 31, 2019.

Nutrition & Biosciences Financing

In connection with the Proposed N&B Transaction, DuPont and Nutrition & Biosciences, Inc. (presently a wholly owned subsidiary of DuPont) (“N&B Inc.”) entered into a Bridge Commitment Letter (the “Bridge Letter”) in an aggregate principal amount of $7.5 billion (the “Bridge Loans”) to secure committed financing for the Special Cash Payment and related financing fees. The aggregate commitment under the Bridge Letter is reduced by, among other things, (1) the amount of net cash proceeds received by N&B Inc. from any issuance of senior unsecured notes pursuant to a Rule 144A offering or other private placement (the "N&B Notes Offering") and (2) certain qualifying term loan commitments under senior unsecured term loan facilities.

In January 2020, N&B Inc. entered into a senior unsecured term loan agreement in the amount of $1.25 billion split evenly between three- and five-year facilities. As a result of entry into the term loan agreement, the commitments under the Bridge Commitment Letter were reduced to $6.25 billion. The remaining $6.25 billion is expected to be funded through the N&B Notes Offering and/or the Bridge Loans. The proceeds from drawdowns on the term loan facilities and the N&B Notes Offering, if any, and/or Bridge Loans would be used to make the Special Cash Payment and to pay the related transaction fees and expenses. The commitments under the Bridge Letter and the availability of funding under the term loan are subject to customary closing conditions including among others, the satisfaction of substantially all the conditions to the consummation of the proposed transaction with IFF.

Equity [Abstract]

STOCKHOLDERS' EQUITY AND ACCUMULATED OTHER COMPREHENSIVE LOSS

STOCKHOLDERS' EQUITY

On May 23, 2019, stockholders of DowDuPont approved a 1-for-3 reverse stock split of DowDuPont shares of common stock with par value of $0.01 per share, which became effective immediately following the Corteva Distribution on June 1, 2019. All comparable periods presented have been retrospectively revised to reflect this change.

Share Repurchase Program

On June 1, 2019, the Company's Board of Directors approved a new $2 billion share buyback program, which expires on June 1, 2021. For the year ended December 31, 2019, the Company had repurchased and retired 10.8 million shares under this program at a total cost of $750 million.

Treasury Stock

On June 25, 2019, the Company retired 37 million shares of its common stock held in treasury. The shares were returned to the status of authorized but unissued shares. As a result, the treasury stock balance decreased by $7,102 million. As a part of the retirement, the Company reduced "Common stock" and "(Accumulated Deficit) Retained Earnings" by $0.04 million and $7,102 million, respectively.

The following table provides a reconciliation of Historical Dow Common Stock activity for the year ended December 31, 2017:

1. On November 1, 2017, Historical EID acquired FMC's H&N Business. The excess of the consideration for the H&N Business over the net fair value of assets acquired and liabilities assumed resulted in the recognition of $732 million of goodwill, of which $14 million was recorded in 2018 as a measurement period adjustment.

2. The prior year amounts have been revised for a reclassification of allocated goodwill between reporting units.

The Company tests goodwill for impairment annually during the fourth quarter, or more frequently when events or changes in circumstances indicate that the fair value is below its carrying value. As a result of the related acquisition method of accounting in connection with the Merger, Historical EID’s assets and liabilities were measured at fair value resulting in increases to the Company’s goodwill and other intangible assets. The fair value valuation increased the risk that any declines in financial projections, including changes to key assumptions, could have a material, negative impact on the fair value of the Company’s reporting units and assets, and therefore could result in an impairment.

In preparation for the Corteva Distribution, Historical EID completed the separation of the assets and liabilities related to its specialty products businesses into separate legal entities (the “SP Legal Entities”) and on May 1, 2019, Historical EID completed the Internal SP Distribution. The Internal SP Distribution served as a triggering event requiring the Company to perform an impairment analysis related to goodwill carried by its Historical EID existing reporting units as of May 1, 2019. Subsequent to the Corteva Distribution, on June 1, 2019, the Company realigned certain businesses resulting in changes to its management and reporting structure, including the creation of a new Non-Core segment. As part of the Second Quarter Segment Realignment, the Company assessed and re-defined certain reporting units effective June 1, 2019, including reallocation of goodwill on a relative fair value basis as applicable to new reporting units identified. Goodwill impairment analyses were then performed for reporting units impacted by the Second Quarter Segment Realignment.

In connection with the analyses described above, the Company recorded aggregate, pre-tax, non-cash impairment charges of $1,175 million for the year ended December 31, 2019 impacting the Nutrition & Biosciences and Non-Core segments. As part of this analysis, the Company determined that the fair value of its Industrial Biosciences reporting unit was below carrying value resulting in a pre-tax, non-cash goodwill impairment charge of $933 million. The Industrial Biosciences reporting unit, part of the Nutrition & Biosciences segment prior to the Second Quarter Segment Realignment, was comprised solely of Historical EID assets and liabilities, the carrying values of which were measured at fair value in connection with the Merger, and thus considered at risk for impairment. Revised financial projections of the Industrial Biosciences reporting unit reflected unfavorable market conditions, driven by slowed demand in the biomaterials business unit which was realigned to the new Non-Core segment effective June 1, 2019, coupled with challenging conditions in U.S. bioethanol markets. These revised financial projections resulted in a reduction in the long-term forecasts of sales and profitability as compared to prior projections. The $242 million in goodwill impairment charges impacting the Non-Core segment also relates to multiple reporting units comprised solely of Historical EID assets and liabilities, the carrying values of which were measured at fair value in connection with the Merger, and thus considered at risk for impairment. The impairment charges impacting Non-Core were determined through utilization of the market approach which was considered most appropriate as the Company continues to evaluate strategic options for these businesses. As a result of the impairment, these Non-Core reporting units' carrying value are indicative of fair value and are at risk to have impairment charges in future periods.

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

In the fourth quarter of 2019, the Company performed quantitative testing on all of its reporting units and determined that no further impairments existed. The Company used a combination of discounted cash flow models (a form of the income approach) utilizing Level 3 unobservable inputs and the Guideline Public Company Method (a form of the market approach). The Company’s significant assumptions in these analyses include, but are not limited to, projected revenue, EBITDA margins, the weighted average cost of capital, the terminal growth rate, derived multiples from comparable market transactions and other market data. As of the fourth quarter testing date, a reporting unit within the Electronics & Imaging segment had limited headroom between the estimated fair value and the carrying value. Subsequent to the fourth quarter testing date, in connection with the Electronics & Imaging realignment of its product lines, this reporting unit is now a part of different reporting unit. The new reporting unit is not considered at risk for impairment.

Equity Method Investment Impairment Related Charges

During the second quarter of 2019, in preparation for the Corteva Distribution, Historical EID completed the separation of the assets and liabilities related to its specialty products businesses into separate legal entities (the “SP Legal Entities”) and on May 1, 2019, Historical EID distributed the SP Legal Entities to DowDuPont (the “Internal SP Distribution”). The Internal SP Distribution served as a triggering event requiring the Company to perform an impairment analysis related to equity method investments held by the Company as of May 1, 2019. The Company applied the net asset value method under the cost approach to determine the fair value of the equity method investments in the Nutrition & Biosciences segment. Based on updated projections, the Company determined the fair value of the equity method investment was below the carrying value and had no expectation the fair value would recover in the short-term due to the current economic environment. As a result, management concluded the impairment was other-than-temporary and recorded an impairment charge of $63 million in “Restructuring and asset related charges - net” in the second quarter of 2019. This impairment charge related to the Nutrition & Biosciences segment. See Notes 14 and 23 for additional information.

Other Impairment Related Charges

In the fourth quarter of 2017, the Company recognized other pretax impairment charges of $71 million, including charges related to manufacturing assets. The impairment charges were included in "Restructuring and asset related charges - net" in the Consolidated Statements of Operations and related to Electronics & Imaging ($39 million) and Safety & Construction ($32 million).

RECENT ACCOUNTING GUIDANCE (Notes)

Recent Accounting Guidance [Abstract]

New Accounting Pronouncements and Changes in Accounting Principles [Text Block]

RECENT ACCOUNTING GUIDANCE

Recently Adopted Accounting Guidance

In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, Leases (Topic 842), and associated ASUs related to Topic 842, which requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. The new guidance requires that a lessee recognize assets and liabilities for leases, and recognition, presentation and measurement in the financial statements depends on whether the lease is classified as a finance or operating lease. In addition, the new guidance requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. Lessor accounting remains largely unchanged from previous U.S. GAAP but does contain some targeted improvements to align with the new revenue recognition guidance, referred to as "Topic 606," issued in 2014.

The Company adopted the new standard in the first quarter of 2019, which allows for a modified retrospective transition approach, applying the new standard to all leases existing at the date of initial adoption. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statement as its date of initial application. The Company has elected to apply the transition requirements at the January 1, 2019 effective date rather than at the beginning of the earliest comparative period presented. This approach allows for a cumulative effect adjustment in the period of adoption, and prior periods are not restated and continue to be reported in accordance with historic accounting under ASC 840 (Leases). In addition, the Company has elected the package of practical expedients permitted under the transition guidance within the new standard which does not require reassessment of prior conclusions related to contracts containing a lease, lease classification and initial direct lease costs. As an accounting policy election, the Company chose to not apply the standard to certain existing land easements, excluded short-term leases (term of 12 months or less) from the balance sheet and accounts for nonlease and lease components in a contract as a single component for all asset classes. The following table summarizes the impact of adoption to the Consolidated Balance Sheet:

1. The as reported December 31, 2018 information has been updated to reflect the impact of the reverse stock split and the change in accounting policy discussed in Note 1.

2. The net impact to retained earnings was primarily a result of the recognition of a deferred gain associated with a prior sale-leaseback transaction.

The adoption of the new guidance did not have a material impact on the Company's Consolidated Statement of Operations and had no impact on the Consolidated Statement of Cash Flows.

In August 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Topic 715-20), Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. This amendment modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans by removing and adding certain disclosures for these plans. The eliminated disclosures include the amounts in "Accumulated Other Comprehensive Income" expected to be recognized in net periodic benefit costs over the next fiscal year and the effects of a one-percentage-point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for postretirement health care benefits. New disclosures include the interest crediting rates for cash balance plans, and an explanation of significant gains and losses related to changes in benefit obligations. The new standard is effective for fiscal years beginning after December 15, 2020, and must be applied retrospectively for all periods presented. Early adoption is permitted. The Company early adopted the new guidance in the fourth quarter of 2019, and adoption did not have a material impact on the Consolidated Financial Statements.

Accounting Guidance Issued But Not Adopted at December 31, 2019

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and associated ASUs related to Topic 326. The new guidance introduces the current expected credit loss (“CECL”) model, which requires organizations to record an allowance for credit losses for certain financial instruments and financial assets, including trade receivables, based on expected losses rather than incurred losses. Under this update, on initial recognition and at each reporting period, an entity will be required to recognize an allowance that reflects the entity’s current estimate of credit losses expected to be incurred over the life of the financial instrument. This update will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, and early adoption is permitted.

The Company has a cross-functional team in place to evaluate and implement the new guidance and the Company has substantially completed the implementation of the standard to be in compliance with accounting and reporting requirements. The team continues to review existing financial instruments and update business processes and controls related to the new guidance for credit losses. Collectively, these activities are expected to facilitate the Company's ability to meet the new accounting and disclosure requirements upon adoption in the first quarter of 2020.

The ASU requires a modified retrospective transition approach, applying the new standards cumulative-effect adjustment as of the beginning of the first reporting period in which the guidance is effective. Therefore, this cumulative-effect will be reflected as of January 1, 2020 and prior periods will not be restated. The Company is finalizing the evaluation of the January 1, 2020 impact and estimates that the impact to the Company’s Consolidated Balance Sheet will not be material. The impact to the Company's Consolidated Statements of Operations and Consolidated Statement of Cash Flows is expected not to be material.

PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

PENSION PLANS AND OTHER POST EMPLOYMENT BENEFITS

Historical Dow and Historical EID did not merge their defined benefit pension and other post employment benefit (OPEB) plans as a result of the Merger. See Note 3 for additional information on the Merger. In connection with the Distributions, the Historical Dow U.S. qualified defined benefit plan and the Historical EID U.S. principal qualified defined benefit plan were separated from the Company to Dow and Corteva, respectively. The defined benefit pension plans that were related to Historical Dow that were not separated with Dow or Corteva were not merged with any Historical EID plans. The Company retained a portion of pension liabilities relating to foreign benefit plans for both Historical EID and Historical Dow. The Company retained select OPEB liabilities relating to foreign Historical EID benefit plans but did not retain any Historical Dow OPEB plans. The Company also retained an immaterial portion of the non-qualified US pension liabilities and other post employment benefit plans relating to Historical EID US benefit plans. The significant defined benefit pension and OPEB plans of Historical Dow and Historical EID are summarized below.

Defined Benefit Pension Plans

Historical Dow

Historical Dow had both funded and unfunded defined benefit pension plans that covered employees in the United States and a number of other countries. The U.S. qualified plan covering the parent company was the largest plan. Benefits for employees hired before January 1, 2008, were based on length of service and the employee’s three highest consecutive years of compensation. Employees hired after January 1, 2008, earned benefits based on a set percentage of annual pay, plus interest.

The Employee Matters Agreement with Dow provides that employees of Dow no longer participate in benefit plans sponsored or maintained by the Company, and that employees of the Company no longer participate in benefit plans sponsored or maintained by Dow, as of the effective time of the Dow Distribution. The U.S. qualified plan is no longer an obligation of the Company, the fundings, maintenance and ultimate payout of the plan is the sole responsibility of Dow. Historical Dow's funding policy was to contribute to the plans when pension laws and/or economics either require or encourage funding.

The Company has both funded and unfunded defined benefit pension plans that cover employees in a number of non-US countries.

Historical EID

Historical EID had both funded and unfunded noncontributory defined benefit pension plans covering a majority of the U.S. employees. The U.S. qualified plan was the largest pension plan held by Historical EID. Most employees hired on or after January 1, 2007, were not eligible to participate in the U.S. defined benefit pension plans. The benefits under these plans were based primarily on years of service and employees' pay near retirement. Historical EID froze the pay and service amounts used to calculate pension benefits for employees who participated in the U.S. pension plans as of November 30, 2018. Therefore, as of November 30, 2018, employees that participated in the U.S. pension plans no longer accrued additional benefits for future service and eligible compensation received.

The Employee Matters Agreement with Corteva provides that employees of Corteva no longer participate in benefit plans sponsored or maintained by the Company, and that employees of the Company no longer participate in benefit plans sponsored or maintained by Corteva, as of the effective time of the Corteva Distribution. The U.S. qualified plan is no longer an obligation of the Company; the fundings, maintenance and ultimate payout of the plan is the sole responsibility of Corteva Inc. The Company has both funded and unfunded defined benefit pension plans that cover executives in the United States and employees in a number of non-US countries.

Historical EID's funding policy was consistent with the funding requirements of federal laws and regulations. Pension coverage for employees of Historical EID's non-U.S. consolidated subsidiaries was 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. Total 2019 contributions also includes contributions to fund benefit payments for Historical EID's pension plans where funding is not customary.

DuPont

DuPont has both funded and unfunded defined benefit pension plans covering employees in a number of non-US countries that formerly relate to both Historical Dow and Historical EID. The United Kingdom qualified plan is the largest pension plan held by DuPont.

DuPont's funding policy is consistent with the funding requirements of each country's laws and regulations. Pension coverage for employees of DuPont'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. During 2019, the Company contributed $697 million to its pension plans, which included $139 million of contributions to plans that were separated in connection with the Distributions. DuPont expects to contribute approximately $85 million to its pension plans in 2020.

The weighted-average assumptions used to determine pension plan obligations and net periodic benefit costs for all plans are summarized in the table below:

Weighted-Average Assumptions for Pension Plans	Benefit Obligations  at December 31,				Net Periodic Costs for the Years Ended
	2019		2018		2019 1		2018		2017 2
Discount rate	1.21	%	3.80	%	3.80	%	3.26	%	3.50	%
Interest crediting rate for applicable benefits	1.25	%	3.72	%	3.72	%	3.61	%	3.45	%
Rate of compensation increase 3	3.14	%	3.42	%	3.42	%	3.95	%	3.88	%
Expected return on plan assets	—		—		6.46	%	6.68	%	6.94	%

1. Includes three months of Dow activity (January - March), five months of Corteva activity (January - May) and twelve months of DuPont activity, all based on dates of the Distributions.

2. Includes Historical EID plans subsequent to the Merger date.

3. The December 31, 2018 rate did not include Historical EID's U.S. pension plans as employees of these plans no longer accrued additional benefits for future service and eligible compensation.

Other Post employment Benefit Plans

Historical Dow

Historical Dow provided certain health care and life insurance benefits to retired employees and survivors. Historical Dow’s plans outside of the United States were not significant; therefore, this discussion relates to the U.S. plans only. The plans provide health care benefits, including hospital, physicians’ services, drug and major medical expense coverage, and life insurance benefits. In general, for employees hired before January 1, 1993, the plans provide benefits supplemental to Medicare when retirees are eligible for these benefits. Historical Dow and the retiree share the cost of these benefits, with the Historical Dow portion increasing as the retiree has increased years of credited service, although there was a cap on the Historical Dow portion. Historical Dow had the ability to change these benefits at any time. Employees hired after January 1, 2008, are not covered under the plans.

The Employee Matters Agreement with Dow provides that employees of Dow no longer participate in benefit plans sponsored or maintained by the Company, and that employees of the Company no longer participate in benefit plans sponsored or maintained by Dow, as of the effective time of the Dow Distribution.

No Historical Dow other post-employment benefit plans were retained by the Company in connection with the Dow Distribution. All other post-employment benefit plans both those inside the US and those outside, are the sole responsibility of Dow.

Historical EID

Historical EID provided medical, dental and life insurance benefits to pensioners and survivors. The associated plans for retiree benefits were unfunded and the cost of the approved claims was paid from Historical EID company funds. Essentially 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 pensioners and survivors' contributions adjusted annually to achieve a 50/50 target for sharing of cost increases between Historical EID and pensioners and survivors. In addition, limits were applied to Historical EID's portion of the retiree medical cost coverage. For Medicare eligible pensioners and survivors, Historical EID provided a funded Health Reimbursement Arrangement ("HRA"). In November 2016, Historical EID announced that OPEB eligible employees who will be under the age of 50 as of November 30, 2018, as defined above, will not receive post-employment medical, dental and life insurance benefits. Beginning January 1, 2015, eligible employees who retire on and after that date will receive the same life insurance benefit payment, regardless of the employee's age or pay. The majority of U.S. employees hired on or after January 1, 2007, are not eligible to participate in the post-employment medical, dental and life insurance plans.

The Employee Matters Agreement with Corteva provides that employees of Corteva no longer participate in benefit plans sponsored or maintained by the Company, and that employees of the Company no longer participate in benefit plans sponsored or maintained by Corteva, as of the effective time of the Corteva Distribution. The vast majority of U.S. other post employment benefit obligations are no longer the obligations of the Company; the fundings, maintenance and ultimate payout of the plans are the sole responsibility of Corteva Inc.

DuPont

The Company retained U.S. and foreign other post employment benefit obligations with the Canadian plan being the largest plan and accounting for the vast majority of the Company's total other post employment benefit obligations. In comparison to the Company's defined benefit pension plans, the Company's other post-employment benefit plans are not significant.

The weighted-average assumptions used to determine other post-employment benefit obligations and net periodic benefit costs are provided below:

Weighted-Average Assumptions for Other Postretirement Benefits Plans	Benefit Obligations  at December 31,				Net Periodic Costs for the Year Ended
	2019		2018		2019 1		2018		2017 2
Discount rate	3.10	%	4.23	%	4.23	%	3.54	%	3.76	%
Health care cost trend rate assumed for next year	N/A		7.15	%	7.15	%	6.52	%	7.00	%
Rate to which the cost trend rate is assumed to decline (the ultimate health cost care trend rate)	N/A		5.00	%	5.00	%	5.00	%	5.00	%
Year that the rate reaches the ultimate health care cost trend rate:
Historical Dow plans	N/A		2025		2025		2025		2025
Historical EID plans	N/A		2028		2028		2023		2023

1. Includes three months of Dow activity (January - March), five months of Corteva activity (January - May) and twelve months of DuPont activity, all based on dates of the Distributions.

2. Includes Historical EID plans subsequent to the Merger date.

Assumptions

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.

Service cost and interest cost for all other plans are determined on the basis of the discount rates derived in determining those plan obligations.The discount rates utilized to measure the majority of pension and other postretirement obligations are based on the Aon AA corporate bond yield curves applicable to each country at the measurement date. DuPont utilizes the mortality tables and generational mortality improvement scales, where available, developed in each of the respective countries in which the Company holds plans.

A significant component of the overall decrease in the Company's actuarial losses for the year ended December 31, 2019 was due to the Distributions and the spins of the Company's main US plans. The increase in the Company's actuarial losses for the year ended December 31, 2018 was primarily due to the changes in weighted-average discount rates, which increased from 3.26 percent at December 31, 2017 to 3.80 at December 31, 2018.

The accumulated benefit obligation for all pension plans was $4.5 billion and $51.4 billion at December 31, 2019 and 2018, respectively.

Plan Assets

Historical Dow

Plan assets consist primarily of equity and fixed income securities of U.S. and foreign issuers, and include alternative investments such as real estate, private market securities and absolute return strategies. At December 31, 2018, plan assets totaled $22.5 billion and included no directly held common stock of DowDuPont.

Historical Dow's investment strategy for the plan assets was to manage the assets in relation to the liability in order to pay retirement benefits to plan participants over the life of the plans. This was accomplished by identifying and managing the exposure to various market risks, diversifying investments across various asset classes and earning an acceptable long-term rate of return consistent with an acceptable amount of risk, while considering the liquidity needs of the plans.

The plans were permitted to use derivative instruments for investment purposes, as well as for hedging the underlying asset and liability exposure and rebalancing the asset allocation. The plans used value-at-risk, stress testing, scenario analysis and Monte Carlo simulations to monitor and manage both the risk within the portfolios and the surplus risk of the plans.

Equity securities primarily included investments in large- and small-cap companies located in both developed and emerging markets around the world. Fixed income securities included investment and non-investment grade corporate bonds of companies diversified across industries, U.S. treasuries, non-U.S. developed market securities, U.S. agency mortgage-backed securities, emerging market securities and fixed income related funds. Alternative investments primarily included investments in real estate, private equity limited partnerships and absolute return strategies. Other significant investment types included various insurance contracts and interest rate, equity, commodity and foreign exchange derivative investments and hedges.

Historical Dow mitigated the credit risk of investments by establishing guidelines with investment managers that limit investment in any single issue or issuer to an amount that was not material to the portfolio being managed. These guidelines were monitored for compliance both by Historical Dow and external managers. Credit risk related to derivative activity was mitigated by utilizing multiple counterparties, collateral support agreements and centralized clearing, where appropriate.

Historical EID

Plan assets consisted primarily of equity and fixed income securities of U.S. and foreign issuers, and included alternative investments such as real estate and private market securities. At December 31, 2018, plan assets totaled $18.9 billion and included directly held common stock of DowDuPont of $684 million.

Historical EID established 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 were selected in accordance with the laws and practices of those countries. Where appropriate, asset liability studies were utilized in this process. U.S. plan assets and a portion of non-U.S. plan assets are managed by investment professionals employed by Historical EID. The remaining assets are managed by professional investment firms unrelated to Historical EID. Historical EID's pension investment professionals had discretion to manage the assets within established asset allocation ranges approved by management. Additionally, pension trust funds were permitted to enter into certain contractual arrangements generally described as derivative instruments. Derivatives were primarily used to reduce specific market risks, hedge currency and adjust portfolio duration and asset allocation in a cost-effective manner.

Global equity securities include varying market capitalization levels. U.S. equity investments are primarily large-cap companies. 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.

DuPont

Plan assets consist primarily of equity and fixed income securities of U.S. and foreign issuers, and alternative investments such as pooled investment vehicles and private market securities. At December 31, 2019, plan assets totaled $3.8 billion and included directly held common stock of DuPont of less than $1 million.

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

Equity securities	25	%
Fixed income securities	19
Alternative investments	10
Other investments	46
Total	100	%

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 other pension plan assets for which observable inputs are used, fair value is derived through the use of fair value models, such as a discounted cash flow model or other standard pricing models.

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.

Certain pension plan assets are held in funds where fair value is based on an estimated net asset value per share (or its equivalent) as of the most recently available fund financial statements which are received 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 to arrive at an estimated net asset value per share at the measurement date. Where available, audited annual financial statements are obtained and reviewed for the investments as support for the manager’s investment valuation. These funds are not classified within the fair value hierarchy.

The following table summarizes the bases used to measure the Company’s pension plan assets at fair value for the years ended December 31, 2019 and 2018:

Trust Assets

Historical EID entered into a trust agreement in 2013 (as amended and restated in 2017) that established and required Historical EID to fund a trust (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. After the distribution of Corteva, the Trust assets related to Corteva employees were transferred to a new trust for Corteva. As a result, the Trust currently held by DuPont relates solely to funding obligations to DuPont employees. At December 31, 2019, the balance in the Trust was $37 million compared to $43 million at December 31, 2018.

Defined Contribution Plans

Historical Dow

U.S. employees participated in defined contribution plans (Employee Savings Plans or 401(k) plans) by contributing a portion of their compensation, which was partially matched by Historical Dow. Defined contribution plans also covered employees in some subsidiaries in other countries, including Australia, Brazil, Canada, Italy, Spain and the United Kingdom. Expense recognized for all defined contribution plans was $242 million in 2018 and $367 million in 2017.

Historical EID

Historical EID provided defined contribution benefits to its employees. The most significant was the U.S. Retirement Savings Plan ("the Plan"), which covered all U.S. full-service employees. This Plan included a non-leveraged Employee Stock Ownership Plan ("ESOP"). Employees were not required to participate in the ESOP and those who did were free to diversify out of the ESOP. The purpose of the Plan was to provide retirement savings benefits for employees and to provide employees an opportunity to become stockholders of the Company. The Plan was a tax qualified contributory profit sharing plan, with cash or deferred arrangement and any eligible employee of Historical EID could participate. Historical EID's contributions to the Plan were $183 million in 2018 and post-Merger contributions were $53 million in 2017. Historical EID's matching contributions vested immediately upon contribution. The 3 percent nonmatching employer contribution vested after employees completed three years of service.

In addition, Historical EID made contributions to other defined contribution plans of $51 million in 2018 and post-Merger contributions to other defined contribution plans of $17 million in 2017.

DuPont

The Company provides defined contribution benefits to its employees. The most significant is the U.S. Retirement Savings Plan ("the Plan"), which covers all 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 the Company may participate. Currently, the Company 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. The Company's matching contributions vest immediately upon contribution. The 3 percent nonmatching employer contribution vests after employees complete three years of service. The Company's contributions to the Plan in 2019 related to continuing operations were $82 million.

In addition, the Company made contributions to other defined contribution plans in 2019 in the amount of $24 million related to continuing operations.

Dec. 31, 2019

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENT LIABILITIES

NTS AND CONTINGENT LIABILITIES

Litigation and Environmental Matters

As of December 31, 2019, the Company had recorded liabilities of $20 million associated with litigation matters and $77 million associated with environmental matters. These recorded liabilities include the Company’s indemnification obligations to each of Dow and Corteva.

Under the Separation and Distribution Agreement, liabilities, including cost and expenses, associated with litigation and environmental matters that primarily related to the materials science business, the agriculture business or the specialty products business were generally allocated to or retained by Dow, Corteva or the Company, respectively, through retention, assumption or indemnification. Related to the foregoing, at December 31, 2019, DuPont has recorded (i) a liability of $35 million (although it is reasonably possible that the ultimate cost could range up to $108 million above the amount accrued) for retained or assumed environmental liabilities, (ii) a liability of $3 million for retained or assumed litigation liabilities, and (iii) an indemnification liability related to legal and environmental matters of $58 million. Liabilities associated with discontinued and/or divested operations and businesses of Historical Dow generally were allocated to or retained by Dow. The allocation of liabilities associated with the discontinued and/or divested operations and businesses of Historical EID is discussed below.

The liabilities allocated to and assumed by Dow and Corteva are reflected as discontinued operations of the Company at December 31, 2018. Such liabilities assumed by Dow as of the consummation of the Dow Distribution on April 1, 2019 include the following: Asbestos-Related Matters of Union Carbide Corporation, Urethane Matters, Rocky Flats Matter, Dow Silicones Chapter 11 Related Matters, Midland Off-Site Environmental Matters, Dow Silicones Midland, Michigan, Freeport, Texas, Plaquemine, Louisiana and St. Charles, Louisiana Steam-Assisted Flares Matters, Freeport, Texas, Facility Matter, Mt. Meigs, Alabama Matter, Union Carbide Matter and Union Carbide - Seadrift, Texas and, with indemnity from DuPont and Corteva, the Sabine Plant, Orange Texas-EPA Multimedia Inspection. Such liabilities assumed by Corteva as of the consummation of the Corteva Distribution on June 1, 2019, include the following: La Porte Plant, La Porte, Texas - Crop Protection-Release Incident Investigation and La Porte Plant, La Porte, Texas - EPA Multimedia Inspection.

Discontinued and/or Divested Operations and Businesses ("DDOB") Liabilities of Historical EID

Under the Separation and Distribution Agreement and the Letter Agreement between Corteva and DuPont, DDOB liabilities of Historical EID primarily related to Historical EID’s agriculture business were allocated to or retained by Corteva and those primarily related to Historical EID’s specialty products business were allocated to or retained by the Company. Historical EID DDOB liabilities not primarily related to Historical EID’s agriculture business or specialty products business (“Stray Liabilities”), are allocated as follows

• Generally, indemnifiable losses as defined in the Separation and Distribution Agreement, (“Indemnifiable Losses”) for Stray Liabilities, to the extent they do not arise out of actions related to or resulting from the development, testing, manufacture or sale of PFAS, defined below, (“Non-PFAS Stray Liabilities”) that are known as of April 1, 2019 are borne by Corteva up to a specified amount set forth in the schedules to the Separation and Distribution Agreement and/or Letter Agreement. Non-PFAS Stray Liabilities in excess of such specified amounts and any Non-PFAS Stray Liabilities not listed in the schedules to the Separation and Distribution Agreement or Letter Agreement are borne by Corteva and/or DuPont up to separate, aggregate thresholds of $200 million each to the extent Corteva or DuPont, as applicable, incurs an Indemnifiable Loss. Once Corteva’s or DuPont’s $200 million threshold is met, the other

would generally bear all Non-PFAS Stray Liabilities until meeting its $200 million threshold. After the respective $200 million thresholds are met, DuPont will bear 71 percent of such losses and Corteva will bear 29 percent of such losses.

• Generally, Corteva and the Company will each bear 50 percent of the first $300 million (up to $150 million each) for Indemnifiable Losses arising out of actions to the extent related to or resulting from the development, testing, manufacture or sale of per- or polyfluoroalkyl substances, which include collectively perfluorooctanoic acids and its salts (“PFOA”), perfluorooctanesulfonic acid (“PFOS”) and perfluorinated chemicals and compounds (“PFCs”) (all such substances, “PFAS” and such Stray Liabilities referred to as “PFAS Stray Liabilities”). Indemnifiable Losses to the extent related to PFAS Stray Liabilities in excess of $300 million generally will be borne 71 percent by the Company and 29 percent by Corteva, unless either Corteva or DuPont has met its $200 million threshold. In that event, the other company would bear all PFAS Stray Liabilities until that company meets its $200 million threshold, at which point DuPont will bear 71 percent of such losses and Corteva will bear 29 percent of such losses.

• Indemnifiable Losses incurred by the companies in relation to PFAS Stray Liabilities up to $300 million (e.g., up to $150 million each) will be applied to each company’s respective $200 million threshold.

Non-PFAS Stray Liabilities

While DuPont believes it is probable that it will incur a liability related to Non-PFAS Stray Liabilities, such liability is not reasonably estimable at December 31, 2019. Therefore, at December 31, 2019, DuPont has not recorded an accrual related to Non-PFAS Liabilities.

PFAS Stray Liabilities

DuPont expects to continue to incur costs and expenses such as attorneys’ fees and expenses and court costs in connection with the matters described below, which the Company will expense as incurred in accordance with its accounting policy for litigation matters.

Chemours Suit

On July 1, 2015, Historical EID completed the separation of Historical EID’s Performance Chemicals segment through the spinoff of all the issued and outstanding stock of The Chemours Company (“Chemours”) to holders of Historical EID common stock. In connection with the spin, Historical EID and Chemours entered into a Separation Agreement (as amended, the "Chemours Separation Agreement"). Pursuant to the Chemours Separation Agreement, Chemours is obligated to indemnify Historical EID, including its current or former affiliates, against certain litigation, environmental and other liabilities that arose prior to the Chemours Separation. 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, Historical EID and Chemours amended the Chemours Separation Agreement to provide for a limited sharing of potential future PFOA liabilities for a five-year period that began on July 6, 2017. The amended agreement provides that during that five-year period, Chemours will annually pay the first $25 million of future PFOA liabilities and, if that amount is exceeded, Historical EID will pay any excess amount up to the next $25 million, with Chemours annually bearing any excess liabilities above that amount. If Historical EID were required to pay PFOA liabilities pursuant to the amended agreement, fifty percent of such obligation would be borne by the Company in accordance with the Letter Agreement. In connection with the foregoing, the Company has not recorded or paid a PFOA liability. At the end of the five-year period, this limited sharing agreement will expire, and Chemours’ indemnification obligations under the Chemours Separation Agreement will continue unchanged.

On May 13, 2019, Chemours filed suit in the Delaware Court of Chancery against Historical EID, Corteva and the Company in an attempt to limit its responsibility for the litigation and environmental liabilities allocated to and assumed by Chemours under the Chemours Separation Agreement. Chemours is asking the court to rewrite the Chemours Separation Agreement by either limiting Chemours’ liabilities or, alternatively, ordering the return to Chemours of all or a portion of a $3.91 billion dividend that Chemours paid to Historical EID, Chemours’ then-sole-shareholder, just prior to the spin of Chemours. DuPont and Corteva, acting jointly, have filed a motion to dismiss the lawsuit for lack of subject matter jurisdiction and have initiated an arbitration of the dispute as required under the Chemours Separation Agreement. In December 2019, following argument, the Delaware Court of Chancery stayed arbitration pending resolution of the motion to dismiss. The court is expected to rule on the motion in the first quarter of 2020. Indemnifiable Losses related to the Chemours suit are PFAS Stray Liabilities subject to the sharing arrangement between DuPont and Corteva, described above. The Company believes the probability of a final unappealable judgment of liability with respect to the Chemours suit to be remote; the defendants continue to vigorously defend full indemnity rights as set forth in the Chemours Separation Agreement. 

PFAS Matters

Historical EID is a party to legal proceedings relating to the use of PFOA and PFCs by its former Performance Chemicals segment. Indemnifiable Losses related to PFAS liabilities allocated to and assumed by Chemours under the Chemours Separation Agreement generally are PFAS Stray Liabilities subject to the sharing arrangement between DuPont and Corteva, described above.

Generally, Chemours, with reservations, including as to alleged fraudulent conveyance and voidable transactions, is defending and indemnifying Historical EID in the PFAS Matters discussed below. Although Chemours has refused the tender of the Company’s defense in the limited actions in which the Company has been named, DuPont believes it is remote that it will ultimately incur a liability in connection with these PFAS Matters.

Personal Injury and Other PFAS Actions

DuPont, which was formed after the spinoff of Chemours, is not named in the personal injury and other PFAS actions discussed below.

Personal Injury

In 2004, Historical EID settled a West Virginia state court class action, Leach v. DuPont, which alleged that PFOA from Historical EID’s former Washington Works facility had contaminated area drinking water supplies and affected the health of area residents. Historical EID has residual liabilities under the Leach settlement related to 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.

Members of the Leach class have standing to pursue personal injury claims for just six health conditions that an expert panel appointed under the Leach 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. In 2017, Chemours and Historical EID each paid $335 million to settle the multi-district litigation in the U.S. District Court for the Southern District of Ohio (“Ohio MDL”), thereby resolving claims of about 3,550 plaintiffs alleging injury from exposure to PFOA in drinking water. The 2017 settlement did not resolve claims of Leach class members who did not have claims in the Ohio MDL or whose claims are based on diseases first diagnosed after February 11, 2017. To date several dozen claims alleging personal injury, including kidney and testicular cancer claims, have been filed since the 2017 settlement. These claims are currently pending in the Ohio MDL. Trial of a kidney cancer claim and a testicular cancer claim began in the first quarter of 2020 and trial of additional cancer claims are scheduled to begin in June 2020.

Natural Resource Damage Claims and Other Claims for Environmental Damages

In addition to the actions described above, there are about 100 cases alleging damages to natural resources, the environment and/or property as well as various other allegations. DuPont which is named in certain of these actions as discussed below, is increasingly named in suits filed since May 2019.

Drinking Water

Since May 2017, a number of municipal water districts and state attorneys general have filed lawsuits against Historical EID, Chemours, 3M, and others, claiming contamination of public water systems by certain PFAS compounds. Such actions are currently pending in Ohio, Michigan, New Jersey, New Hampshire, New York, and Vermont. Generally, the states seek economic impact damages for alleged harm to natural resources, punitive damages, and present and future costs to cleanup contamination from certain PFAS compounds and to abate the alleged nuisance.

DuPont is a named party in the New Jersey suit related to its site in Parlin, New Jersey. In addition, the New Jersey Attorney General and New Jersey State Department of Environmental Protection filed two directives, one of which names DuPont. The directives seek information on the historical and current use of PFAS. DuPont is also a named party to the Vermont suit and the Michigan suit. The amended complaints in the New Jersey and Vermont cases and the complaint filed by Michigan include additional causes of action based on allegations that the transfer by Historical EID of certain PFAS liabilities to Chemours prior to spinning off Chemours resulted in a fraudulent conveyance or voidable transaction.

Lawsuits have been filed by residents and several water districts against Historical EID and Chemours in New York federal and state courts, including a putative class action, alleging exposure to PFOA from third-party defendant manufacturing operations and seeking compensatory, consequential and punitive damages, medical monitoring and attorneys’ fees, expenses and interest.

Other PFAS Actions

There are several actions pending in federal court against Historical EID and Chemours, relating to discharges of PFCs, including GenX, into the Cape Fear River. GenX is a polymerization processing aid and a replacement for PFOA introduced by Historical EID which Chemours continues to manufacture at its Fayetteville Works facility in Bladen County, North Carolina. One of these actions is a consolidated putative class action that asserts claims for damages and other relief 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. In addition, an action is pending in North Carolina state court on behalf of about 100 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.

Aqueous Film Forming Foam

As of January 2020, more than 200 cases have been filed in various federal and state courts alleging contamination of neighboring drinking and groundwater from the use of aqueous film forming foam to fight fires on military installations, air force bases, commercial airports and refineries. The majority of these cases have been transferred, or will be transferred, to a multi-district litigation docket in federal district court in South Carolina (the “SC MDL”). Historical EID and Chemours are named in about 150 of these cases, approximately 100 of which also name the Company. The number of cases filed that name as a defendant, the Company, among others including Historical EID and Chemours, has increased significantly since May 2019. In addition, most of these more recent cases were filed directly in the SC MDL and include allegations that exposure to PFAS caused kidney, testicular and other cancers principally in firefighters. 3M and several foam manufacturers are also named defendants in the SC MDL cases. The claims against Historical EID and Chemours involve alleged sales of PFOA and PFOS products to foam manufacturers, including 3M, who are also defendants in the SC MDL. Historical EID and the Company have never made or sold aqueous film forming foam, PFOS or PFOS containing products.

Additionally, a case filed by a former firefighter is pending in the Southern District of Ohio seeking certification of a nationwide class of individuals who have detectable levels of PFAS in their blood serum. The suit was filed against 3M and several other defendants in addition to Chemours and Historical EID. The complaint specifically seeks, among other things, the creation of a “PFAS Science Panel” to study the effects of PFAS, but expressly states that the class does not seek compensatory damages for personal injuries. In February 2020, the court denied the defendants' motion to transfer this case to the SC MDL.

Other Litigation Matters

In addition to the specific matters described above, the Company is party to other claims and lawsuits arising out of the normal course of business with respect to product liability, patent infringement, governmental regulation, contract and commercial litigation, and other actions. Certain of these actions may purport to be class actions and seek damages in very large amounts. It is the opinion of the Company’s management that the possibility is remote that the aggregate of all such other claims and lawsuits will have a material adverse impact on the results of operations, financial condition and cash flows of the Company.

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 based on current law and existing technologies. At December 31, 2019, the Company had accrued obligations of $77 million for probable environmental remediation and restoration costs, inclusive of $35 million retained and assumed following the Distributions and $42 million of indemnified liabilities. These obligations are included in "Accrued and other current liabilities" and "Other noncurrent obligations" in the 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 $170 million above the amount accrued at December 31, 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. At December 31, 2018, the Company had accrued obligations of $51 million for probable environmental remediation and restoration costs.

Pursuant to the Separation and Distribution Agreement, the Company is required to indemnify certain clean-up responsibilities and associated remediation costs. The accrued environmental obligations of $77 million as of December 31, 2019 includes amount for which the Company indemnifies Dow and Corteva. At December 31, 2019, the Company has indemnified Dow and Corteva $8 million and $34 million, respectively.

Guarantees

Obligations for Equity Affiliates & Others

The Company has directly guaranteed various debt obligations under agreements with third parties related to equity affiliates and customers. At December 31, 2019 and December 31, 2018, the Company had directly guaranteed $187 million and $199 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. The Company would be required to perform on these guarantees in the event of default by the guaranteed party.

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.

In certain cases, the Company has recourse to assets held as collateral, as well as personal guarantees from customers. Assuming liquidation, these assets are estimated to cover approximately 19 percent of the $22 million of guaranteed obligations of customers. The following table provides a summary of the final expiration year and maximum future payments for each type of guarantee:

Guarantees at December 31, 2019	Final Expiration Year	Maximum Future Payments
In millions
Obligations for customers 1:
Bank borrowings	2020	$	22
Obligations for non-consolidated affiliates2:
Bank borrowings	2020	165
Total guarantees		$	187

1. Existing guarantees for select customers, as part of contractual agreements. The terms of the guarantees are equivalent to the terms of the customer loans that are primarily made to finance customer invoices. Of the total maximum future payments, $22 million had terms less than a year.

2. Existing guarantees for non-consolidated affiliates' liquidity needs in normal operations.

INCOME TAXES

For periods between the Merger and the Distributions, DuPont's consolidated federal income tax group and consolidated tax return included the Dow and Corteva entities. Generally, the consolidated tax liability of the DuPont U.S. tax group for each year was apportioned among the members of the consolidated group in accordance with the terms of the Amended and Restated Tax Matters Agreement. DuPont, Corteva and Dow intend that to the extent Federal and/or State corporate income tax liabilities are reduced through the utilization of tax attributes of the other, settlement of any receivable and payable generated from the use of the other party’s sub-group attributes will be in accordance with the Amended and Restated Tax Matters Agreement.

On December 22, 2017, the Tax Cuts and Jobs Act (“The Act”) was enacted. The Act reduced the U.S. federal corporate income tax rate from 35 percent to 21 percent, required companies to pay a one-time transition tax on earnings of foreign subsidiaries that were previously tax deferred, created new provisions related to foreign sourced earnings, eliminates the domestic manufacturing deduction and moves towards a territorial system. At December 31, 2018, the Company had substantially completed its accounting for the tax effects of The Act.

• As a result of The Act, the Company remeasured its U.S. federal deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21 percent. In prior years, the Company recorded a cumulative benefit of $2,784 million ($118 million benefit in 2018 and $2,666 million benefit in 2017) to “Provision (Credit) for income taxes on continuing operations” in the Consolidated Statements of Operations with respect to the remeasurement of the Company's deferred tax balances.

• The Act required a mandatory deemed repatriation of post-1986 undistributed foreign earnings and profits (“E&P”), which results in a one-time transition tax. The Company recorded a cumulative net charge of $1,574 million ($65 million benefit in 2019, $59 million charge in 2018, and $1,580 million charge in 2017) to "Provision (Credit) for income taxes on continuing operations" with respect to the one-time transition tax.

• In the year ended December 31, 2018, the Company recorded an indirect impact of The Act related to prepaid tax on the intercompany sale of inventory. The amount recorded related to the inventory was a $54 million charge to "Provision for income taxes on continuing operations."

Each year the Company files hundreds of tax returns in the various national, state and local income taxing jurisdictions in which it operates. These tax returns are subject to examination and possible challenge by the tax authorities. Positions challenged by the tax authorities may be settled or appealed by the Company. As a result, there is an uncertainty in income taxes recognized in the Company’s financial statements in accordance with accounting for income taxes and accounting for uncertainty in income taxes. The ultimate resolution of such uncertainties is not expected to have a material impact on the Company's results of operations.

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

Undistributed earnings of foreign subsidiaries and related companies that are deemed to be permanently invested amounted to $7,823 million at December 31, 2019. In addition, the U.S. federal tax imposed by The Act on all accumulated unrepatriated earnings through December 31, 2017, The Act introduced additional U.S. federal tax on foreign earnings, effective as of January 1, 2018. The undistributed foreign earnings at December 31, 2019 may still be subject to certain taxes upon repatriation, primarily where foreign withholding taxes apply. It is not practicable to calculate the unrecognized deferred tax liability on undistributed foreign earnings due to the complexity of the hypothetical calculation.

In connection with the Dow Distribution and the Corteva Distribution, the Company has entered into certain agreements that, among other things, effect the separations, provide for the allocation of assets, employees, liabilities and obligations (including its investments, property and employee benefits and tax-related assets and liabilities) among DuPont, Dow, and Corteva (together, the “Parties” and each a “Party”), and provide a framework for DuPont’s relationship with Dow and Corteva following the Distributions. Effective April 1, 2019, the Parties entered into the following agreements:

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

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

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

• Intellectual Property Cross-License Agreement - DuPont entered into an Intellectual Property Cross-License Agreement with Dow (the “DuPont-Dow IP Cross-License Agreement”). The DuPont-Dow IP Cross-License Agreement sets forth the terms and conditions under which the applicable Parties may use in their respective businesses, following each of the Distributions, certain know-how (including trade secrets), copyrights, software, and certain patents and standards, allocated to another Party pursuant to the Separation and Distribution Agreement.

In addition to the agreements above, DuPont has entered into certain various supply agreements with Dow. These agreements provide for different pricing than the historical intercompany and intracompany practices prior to the Distributions.

Effective June 1, 2019, in connection with the Corteva Distribution, DuPont and Corteva entered into the following agreements:

• Intellectual Property Cross-License Agreement - DuPont and Corteva entered into an Intellectual Property Cross-License Agreement (the “DuPont-Corteva IP Cross-License Agreement”). The DuPont-Corteva IP Cross-License Agreement sets forth the terms and conditions under which the applicable parties may use in their respective businesses, following the Corteva Distribution, certain know-how (including trade secrets), copyrights, software, and certain patents and standards, allocated to another Party pursuant to the Separation and Distribution Agreement.

• Letter Agreement - The Company entered into a letter agreement (the "Letter Agreement") with Corteva that sets forth certain additional terms and conditions related to the Corteva Distribution, including certain limitations on DuPont’s and Corteva's ability to transfer certain businesses and assets to third parties without assigning certain of such Party’s indemnification obligations under the Separation and Distribution Agreement to the other Party to the transferee of such businesses and assets or meeting certain other alternative conditions. The Letter Agreement further outlines the allocation between DuPont and Corteva of liabilities associated with certain legal and environmental matters, including liabilities associated with discontinued and/or divested operations and businesses of Historical EID. See Note 16 for more information regarding the allocation.

• Amended and Restated Tax Matters Agreement - The Parties entered into an amendment and restatement of the Tax Matters Agreement, between DuPont, Corteva and Dow, effective as of April 1, 2019 (as so amended and restated, the “Amended and Restated Tax Matters Agreement”). The Amended and Restated Tax Matters Agreement governs the Parties’ rights, responsibilities and obligations with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and other matters regarding taxes. The Parties amended and restated the Tax Matters Agreement in connection with the Corteva Distribution in order to allocate between DuPont and Corteva certain rights and obligations of the Company provided in the original form of the Tax Matters Agreement. See Note 8 for additional information on the Tax Matters Agreement and the Amended and Restated Tax Matters Agreement.

Management has determined that certain internal distributions and reorganizations, and the distributions of Dow on April 1, 2019, and of Corteva on June 1, 2019, qualified as tax-free transactions under the applicable sections of the Internal Revenue Code. If the completed distribution of Corteva or Dow, in each case, together with certain related transactions, were to fail to qualify for non-recognition treatment for U.S. federal income tax purposes, then the Company could be subject, under the Tax Matters Agreement, to significant tax and indemnification liability. To the extent that the Company is responsible for any liability under

the Amended and Restated Tax Matters Agreement there could be a material adverse impact on the Company's business, financial condition, results of operations and cash flows in future reporting periods.

Integration and Separation Costs

Integration and separation costs for continuing operations to date primarily have consisted of financial advisory, information technology, legal, accounting, consulting, and other professional advisory fees associated with the preparation and execution of activities related to the Merger, the Distributions, and beginning in the fourth quarter of 2019, the intended separation of the Nutrition & Biosciences business. The Company expects costs associated with the intended separation of the Nutrition & Biosciences business to be significant; however, the Company is unable to estimate such costs because there are many factors that could affect the amount and timing of these expenses.

These costs are recorded within "Integration and separation costs" within the Consolidated Statements of Operations.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

Fair Value Measurements on a Recurring Basis

The following tables summarize the basis used to measure certain assets and liabilities at fair value on a recurring basis:

Basis of Fair Value Measurements on a Recurring Basis at December 31, 2019	Significant Other Observable Inputs (Level 2)
In millions
Assets at fair value:
Cash equivalents and restricted cash equivalents 1	$	454
Derivatives relating to: 2
Foreign currency contracts	16
Total assets at fair value	$	470
Liabilities at fair value:
Long-term debt including debt due within one year 3	$	17,251
Derivatives relating to: 3
Foreign currency contracts	17
Total liabilities at fair value	$	17,268

1. Treasury bills, time deposits, and money market funds included in "Cash and cash equivalents" and money market funds included in "Other current assets" in the Consolidated Balance Sheets and held at amortized cost, which approximates fair value.

2. See Note 22 for the classification of derivatives in the Consolidated Balance Sheets.

3. See Note 22 for information on fair value measurements of long-term debt.

Basis of Fair Value Measurements on a Recurring Basis at December 31, 2018	Significant Other Observable Inputs (Level 2)

Assets at fair value:
Cash equivalents and restricted cash equivalents 1	$	8,269
Marketable securities 2	29
Derivatives relating to: 3
Foreign currency contracts	72
Total assets at fair value	$	8,370
Liabilities at fair value:
Long-term debt including debt due within one year 4	$	13,091
Derivatives relating to: 3
Foreign currency contracts	21
Total liabilities at fair value	$	13,112

1. Treasury bills, time deposits, and money market funds included in "Cash and cash equivalents" and money market funds included in "Other current assets" in the Consolidated Balance Sheets and held at amortized cost, which approximates fair value.

2. Primarily time deposits with maturities of greater than three months at time of acquisition.

3. See Note 22 for the classification of derivatives in the Consolidated Balance Sheets

4. See Note 22 for information on fair value measurements of long-term debt.

The Company has equity securities of $1 million and $2 million as of December 31, 2019 and December 31, 2018, respectively, classified as level 1 measurements. The Company’s investments in equity securities are included in “Other investments” in the Consolidated Balance Sheets.

For 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 assets and liabilities 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, or by using observable market data points of similar, more liquid securities to imply the price. For time deposits classified as held-to-maturity investments and reported at amortized cost, fair value is based on an observable interest rate for similar securities. 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. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance/quality checks.

For all other assets and liabilities for which observable inputs are used, fair value is derived through the use of fair value models, such as a discounted cash flow model or other standard pricing models.

There were no transfers between Levels 1 and 2 during the year ended December 31, 2019 and December 31, 2018.

Fair Value Measurements on a Nonrecurring Basis

The following table summarizes the basis used to measure certain assets at fair value on a nonrecurring basis:

Basis of Fair Value Measurements on a Nonrecurring Basis	Significant Other Unobservable Inputs (Level 3)		Total Losses

2017
Assets at fair value:
Long-lived assets, intangible assets, and other assets	$	—	$	(177	)

2019 Fair Value Measurements on a Nonrecurring Basis

During the second quarter of 2019, the Company recorded goodwill impairment charges related to the Nutrition & Biosciences

and the Non-Core segments. See Note 14 for further discussion of these fair value measurements.

The Internal SP Distribution served as a triggering event to assess equity method investments for impairment. The Company recorded an other-than-temporary impairment, classified as Level 3 measurements, on an equity method investment during the second quarter of 2019. The impairment charge of $63 million was recorded in "Restructuring and asset related charges - net" in the Consolidated Statements of Operations. See Note 6 for further discussion of these fair value measurements.

2018 & 2017 Fair Value Measurements on a Nonrecurring Basis

The Company has or will shut down a number of manufacturing, R&D, other non-manufacturing facilities and corporate facilities around the world as part of its restructuring programs. Certain inventory, corporate facilities and manufacturing facilities and related assets, were written down to zero. The related charges totaled $32 million and $177 million for the year ended December 31, 2018 and 2017, respectively, and were included in "Restructuring and asset related charges - net" in the Consolidated Statements of Operations.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2019

Accounting Policies [Abstract]

Basis of Presentation and Significant Accounting Policies [Text Block]

Principles of Consolidation and Basis of Presentation

The accompanying Consolidated Financial Statements of DuPont de Nemours, Inc. ("DuPont” or “the Company”) were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The significant accounting policies described below, together with the other notes that follow, are an integral part of the Consolidated Financial Statements.

Effective August 31, 2017, pursuant to the merger of equals transaction contemplated by the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017 ("DWDP Merger Agreement"), The Dow Chemical Company ("Historical Dow") and E. I. du Pont de Nemours and Company ("Historical EID") each merged with subsidiaries of DowDuPont Inc. ("DowDuPont") and, as a result, Historical Dow and Historical EID became subsidiaries of DowDuPont (the "Merger"). Prior to the Merger, DowDuPont did not conduct any business activities other than those required for its formation and matters contemplated by the DWDP Merger Agreement. For purposes of DowDuPont's financial statement presentation, Historical Dow was determined to be the accounting acquirer in the Merger and Historical EID's assets and liabilities are reflected at fair value as of the Merger Effectiveness Time. The financial statements of Historical Dow for periods prior to the Merger are considered to be the historical financial statements of the Company.

Except as otherwise indicated by the context, the term "Historical Dow" includes Historical Dow and its consolidated subsidiaries, "Historical EID" includes Historical EID and its consolidated subsidiaries, and "Dow Silicones" means Dow Silicones Corporation, a wholly owned subsidiary of Historical Dow.

Consolidation, Policy

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, 2019 and 2018, the maximum exposure to loss related to the nonconsolidated VIEs is not considered material to the Consolidated Financial Statements.

Discontinued Operations

Distributions

Effective as of 5:00 p.m. on April 1, 2019, the Company completed the separation of its materials science business into a separate and independent public company by way of a distribution of Dow Inc. (“Dow”) through a pro rata dividend in-kind of all of the then-issued and outstanding shares of Dow’s common stock (the “Dow Common Stock”), to holders of the Company’s common stock (the “DowDuPont common stock”), as of the close of business on March 21, 2019 (the “Dow Distribution”).

Effective as of 12:01 a.m. on June 1, 2019, the Company completed the separation of its agriculture business into a separate and independent public company by way of a distribution of Corteva, Inc. (“Corteva”) through a pro rata dividend in-kind of all of the then-issued and outstanding shares of Corteva’s common stock (the “Corteva Common Stock”), to holders of the Company’s common stock as of the close of business on May 24, 2019 (the “Corteva Distribution” and, together with the Dow Distribution, the “Distributions”).

Following the Corteva Distribution, DuPont holds the specialty products business as continuing operations. On June 1, 2019, DowDuPont changed its registered name from "DowDuPont Inc." to "DuPont de Nemours, Inc." doing business as "DuPont." Beginning on June 3, 2019, the Company's common stock is traded on the NYSE under the ticker symbol "DD".

These Consolidated Financial Statements present the financial position of DuPont as of December 31, 2019 and 2018 and the results of operations of DuPont for the years ended December 31, 2019, 2018 and 2017 giving effect to the Distributions, with the historical financial results of Dow and Corteva reflected as discontinued operations. The sum of the individual earnings per share amounts from continuing operations and discontinued operations may not equal the total company earnings per share amounts due to rounding. The cash flows and comprehensive income related to Dow and Corteva have not been segregated and are included in the Consolidated Statements of Cash Flows and Consolidated Statements of Comprehensive Income, respectively, for all periods presented. Unless otherwise indicated, amounts or activity of Dow and Corteva are consistently included or excluded from the Notes to the Consolidated Financial Statements based on the respective financial statement line item.

On December 15, 2019, the Company entered into definitive agreements to separate and combine the Nutrition & Biosciences business segment (the "N&B Business") with International Flavors & Fragrances Inc. ("IFF") in a tax-efficient Reverse Morris Trust transaction, (the "Proposed N&B Transaction"). The transaction is expected to close by the end of the first quarter of 2021, subject to approval by IFF shareholders and other customary closing conditions, including regulatory approvals and receipt by DuPont of an opinion of tax counsel. The financial results of the N&B Business are included in continuing operations for the periods presented.

Use of Estimates

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.

Reverse Stock Split

Reverse Stock Split

On June 1, 2019, immediately following the Corteva Distribution, the Company completed a 1-for-3 reverse stock split of DuPont's outstanding common stock (the "Reverse Stock Split") and as a result, DuPont common stockholders now hold one share of common stock of DuPont for every three shares held prior to the Reverse Stock Split. The authorized number of shares of common stock was reduced from 5,000,000,000 shares to 1,666,666,667 shares, par value remained $0.01 per share. Stockholders entitled to fractional shares as a result of the Reverse Stock Split received a cash payment in lieu of receiving fractional shares. All share and share-related information presented in these Consolidated Financial Statements have been retroactively adjusted in all periods presented to reflect the decreased number of shares resulting from the Reverse Stock Split. The retroactive adjustments resulted in the reclassification of $16 million from "Common stock" to "Additional paid-in capital" in the Consolidated Balance Sheets for all periods presented.

Lessee, Leases

Leases

The Company adopted the Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)" in the first quarter of 2019. 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 "Deferred charges and other assets" on the Consolidated Balance Sheets. Operating lease liabilities are included in "Accrued and other current liabilities" and "Other noncurrent obligations" on the Consolidated Balance Sheets. Finance lease ROU assets are included in "Property, plant and equipment - net" and the corresponding lease liabilities are included in "Short-term borrowings and finance lease obligations" and "Long-term debt" on the Consolidated Balance Sheets.  

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, and lease expense is recognized 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. Additionally, for certain equipment leases, the portfolio approach is applied to account for the operating lease ROU assets and lease liabilities. In the Consolidated Statements of Operations, lease expense for operating lease payments 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 Notes 2 and 17 for additional information regarding the Company's leases.

Cash and Cash Equivalents

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

Restricted Cash

Restricted cash represents trust assets of $37 million and $43 million as of December 31, 2019 and 2018, respectively, and is included within "Other current assets" on the Consolidated Balance Sheets. See Note 7 for further information.

Marketable Securities

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.

Fair Value Measurements

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 Transactions and Translations

Foreign Currency Translation

The Company's worldwide operations utilize the U.S. dollar ("USD") or local 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 (local 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 the year, 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 the local currency is the functional currency, assets and liabilities denominated in local 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 loss in equity. Assets and liabilities denominated in other than the local currency are re-measured into the local 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 the period.

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

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.

Prior to the Corteva Distribution, the Company recorded inventory under the last-in, first-out ("LIFO"), first-in, first-out ("FIFO") and average cost methods. During the second quarter of 2019, effective after the Corteva Distribution, DuPont elected to change the method of accounting for inventories of the specialty products business recorded under the LIFO method to the average cost method. The effects of the change in accounting principle have been retrospectively applied to all prior periods presented. See Note 11 for more information regarding the change in inventory accounting method.

Approximately 17 percent and 83 percent of the Company's inventories were accounted for under the FIFO and the average cost methods, respectively, at both December 31, 2019 and December 31, 2018. Inventories accounted for under the FIFO method are primarily comprised of products with shorter shelf lives such as certain food-ingredients and enzymes. The Company establishes allowances for obsolescence of inventory based upon quality considerations and assumptions about future demand and market conditions.

Property, Plant and Equipment

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

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 annually during the fourth quarter, 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.

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. The Company determines fair values for each of the reporting units using a combination of the income approach and/or 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. Under the market approach, the Company selected peer sets based on close competitors and reviewed the EBIT/EBITDA multiples to determine the fair value. See Note 14 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's fair value methodology is primarily based on discounted cash flow techniques.

Definite-lived intangible assets are amortized over their estimated useful lives, generally on a straight-line basis for periods ranging primarily from 1 to 26 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.

Impairment and Disposals of Long-Lived Assets

Impairment and Disposals 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

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 or loss is reported in "Accumulated other comprehensive loss" ("AOCL") until it is cleared to earnings during the same period in which the hedged item affects earnings.

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 AOCL generally remains in AOCL 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.

Environmental Matters

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

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 5 for additional information on revenue recognition.

Cost of Sales

Cost of Sales

Cost of sales 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 and other operational expenses. No amortization of intangibles is included within costs of sales.

Research and Development

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, enhancement of existing products and regulatory approval of new and existing 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

Integration and separation costs includes costs incurred to prepare for and close the Merger, post-Merger integration expenses, the Distributions, and beginning in the fourth quarter of 2019, the intended separation of the Nutrition & Biosciences business. 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

Accruals for legal matters 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 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.

Income Taxes

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 Company accrues for other tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated. The current portion of uncertain income tax positions is included in income taxes payable and the long-term portion is included in other noncurrent obligations in the Consolidated Balance Sheets.

Earnings Per Share [Abstract]

EARNINGS PER SHARE CALCULATIONS

EARNINGS PER SHARE CALCULATIONS

On May 23, 2019, stockholders of DowDuPont approved a reverse stock split of the Company's common stock at a ratio of not less than 2-for-5 and not greater than 1-for-3, with the exact ratio determined by and subject to final approval of the Company’s board of directors. The board of directors approved the Reverse Stock Split with a ratio of 1 new share of DowDuPont common stock for 3 shares of current DowDuPont common stock with par value of $0.01 per share. The Reverse Stock Split became effective immediately following the Corteva Distribution on June 1, 2019. All comparable periods presented have been retrospectively revised to reflect this change.

The following tables provide earnings per share calculations for the years ended December 31, 2019, 2018 and 2017:

Weighted-average common shares - diluted 3	746.3	771.8	532.7
Stock options and restricted stock units excluded from EPS calculations 4	3.3	3.2	0.5

1. Historical Dow restricted stock units are considered participating securities due to Historical Dow's practice of paying dividend equivalents on unvested shares.

2. Earnings per share amounts are computed independently for income from continuing operations, income from discontinued operations and net income attributable to common stockholders. As a result, the per share amounts from continuing operations and discontinued operations may not equal the total per share amounts for net income attributable to common stockholders.

3. As a result of the Merger, the share amounts for the year ended December 31, 2017 reflect a weighted averaging effect of Historical Dow shares outstanding prior to August 31, 2017 and DowDuPont shares outstanding on and after August 31, 2017.

4. These outstanding options to purchase shares of common stock and restricted stock units were excluded from the calculation of diluted earnings per share because the effect of including them would have been antidilutive.

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer [Text Block]

NOTE 5 - REVENUE

Revenue Recognition

Products

Substantially all of DuPont's revenue is derived from product sales. Product sales consist of sales of DuPont's products to supply manufacturers and distributors. DuPont 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.

Revenue from product sales is recognized when the customer obtains control of the Company’s product, which occurs at a point in time, usually upon shipment, with payment terms typically in the range of 30 to 60 days after invoicing depending on business and geographic region. The Company elected the practical expedient to not adjust the amount of consideration for the effects of a significant financing component for all instances in which the period between payment and transfer of the goods will be one year or less. When the Company performs shipping and handling activities after the transfer of control to the customer (e.g., when control transfers prior to 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. The Company elected to use the practical expedient to expense cash and non-cash sales incentives as the amortization period for the costs to obtain the contract would have been one year or less.

The transaction price includes estimates for reductions in revenue from customer rebates and rights of return on product sales. These amounts are estimated based upon the most likely amount of consideration to which the customer will be entitled. All estimates are based on historical experience, anticipated performance, and the Company’s best judgment at the time to the extent it is probable, that a significant reversal of revenue recognized will not occur. All estimates for variable consideration are reassessed periodically.

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.

Disaggregation of Revenue

The Company disaggregates its revenue from contracts with customers by segment and business or major product line and geographic region, as the Company believes it best depicts the nature, amount, timing and uncertainty of its revenue and cash flows. Refer to Note 24 for the breakout of net sales by geographic region.

On June 1, 2019, the Company realigned certain businesses resulting in changes to its management and reporting structure, including the creation of a new Non-Core segment ("Second Quarter Segment Realignment") (refer to Note 24 for additional details). In conjunction with the Second Quarter Segment Realignment, DuPont made the following changes to its major product lines:

• Realigned its product lines within Nutrition & Biosciences as Food & Beverage, Health & Biosciences, and Pharma Solutions;

• Renamed its product lines within Transportation & Industrial (formerly known as Transportation & Advanced Polymers) as Mobility Solutions, Healthcare & Specialty, and Industrial & Consumer (formerly known as Engineering Polymers, Performance Solutions, and Performance Resins, respectively); and

• Realigned and renamed its product lines within Safety & Construction as Safety Solutions, Shelter Solutions, and Water Solutions.

On October 1, 2019, Electronics & Imaging realigned its product lines as Image Solutions, Interconnect Solutions and Semiconductor Technologies.

Contract Balances

From time to time, the Company enters into arrangements in which it receives payments from customers based upon contractual billing schedules. The Company records accounts receivables when the right to consideration becomes unconditional. Contract assets include amounts related to the Company’s contractual right to consideration for completed performance obligations not yet invoiced. Contract liabilities primarily reflect deferred revenue from advance payment for product that the Company has received from customers. The Company classifies deferred revenue as current or noncurrent based on the timing of when the Company expects to recognize revenue.

Revenue recognized for the years ended December 31, 2019 and 2018 from amounts included in contract liabilities at the beginning of the period was $40 million and $37 million, respectively. The amount of contract assets reclassified to receivables as a result of the right to the transaction consideration becoming unconditional was insignificant. The Company did not recognize any asset impairment charges related to contract assets during the period.

At December 31, 2019, the Company had $417 million ($8,226 million at December 31, 2018) 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. At December 31, 2018, the Company had $29 million 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 1 year at the time of purchase. The Company’s investments in held-to-maturity securities are held at amortized cost, which approximates fair value. These 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, interest rate 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 derivatives or 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. 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	December 31, 2019		December 31, 2018

Foreign currency contracts 1	$	26	$	2,057

1. Presented net of contracts bought and sold.

Derivatives not Designated in Hedging Relationships

Foreign Currency Contracts

The Company routinely uses forward 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 certain foreign currency-denominated revenues so that gains and losses on the contracts offset changes in the USD value of the related foreign currency-denominated revenues.

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 soybeans, soybean oil and soybean meal.

Fair Value of Derivative Instruments

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:

Fair Value of Derivative Instruments at December 31, 2019

Foreign currency contracts	Accrued and other current liabilities	$	21	$	(15	)	$	6
Total liability derivatives		$	21	$	(15	)	$	6

1. Counterparty and cash collateral amounts represent the estimated net settlement amount when applying netting and set-off rights included in master netting arrangements between the Company and its counterparties and the payable or receivable for cash collateral held or placed with the same counterparty. The Company held cash collateral of $20 million as of December 31, 2018.

Effect of Derivative Instruments

Foreign currency derivatives not designated as hedges are used to offset foreign exchange gains or losses resulting from the underlying exposures of foreign currency-denominated assets and liabilities. The amount charged on a pretax basis related to foreign currency derivatives not designated as a hedge, which was included in “Sundry income (expense) - net” in the Consolidated Statements of Operations, was a loss of $62 million for the year ended December 31, 2019 ($94 million gain for the year ended December 31, 2018 and $91 million gain for the year ended December 31, 2017). The income statement effects of other derivatives were immaterial.

Reclassification from AOCL

The Company does not expect to reclassify gains related to foreign currency contracts from AOCL to income within the next 12 months.

Earnings Per Share [Abstract]

Schedule of Earnings Per Share

The following tables provide earnings per share calculations for the years ended December 31, 2019, 2018 and 2017:

Net Income for Earnings Per Share Calculations - Basic & Diluted In millions	2019			2018		2017
(Loss) Income from continuing operations, net of tax	$	(614	)	$	405	$	233
Net income from continuing operations attributable to noncontrolling interests	30			39		16
Net income from continuing operations attributable to participating securities 1	1			17		13
(Loss) Income from continuing operations attributable to common stockholders	$	(645	)	$	349	$	204
Income from discontinued operations, net of tax	1,214			3,595		1,058
Net income from discontinued operations attributable to noncontrolling interests	72			116		116
Income from discontinued operations attributable to common stockholders	1,142			3,479		942
Net income attributable to common stockholders	$	497		$	3,828	$	1,146

Earnings Per Share Calculations - Basic Dollars per share	2019			2018		2017
(Loss) Income from continuing operations attributable to common stockholders	$	(0.86	)	$	0.46	$	0.39
Income from discontinued operations attributable to common stockholders	1.53			4.54		1.79
Net income attributable to common stockholders 2	$	0.67		$	4.99	$	2.18

Earnings Per Share Calculations - Diluted Dollars per share	2019			2018		2017
(Loss) Income from continuing operations attributable to common stockholders	$	(0.86	)	$	0.45	$	0.38
Income from discontinued operations attributable to common stockholders	1.53			4.51		1.77
Net income attributable to common stockholders 2	$	0.67		$	4.96	$	2.15

Share Count Information  Shares in Millions	2019	2018	2017
Weighted-average common shares - basic 3	746.3	767.0	526.6
Plus dilutive effect of equity compensation plans 3	—	4.8	6.1
Weighted-average common shares - diluted 3	746.3	771.8	532.7
Stock options and restricted stock units excluded from EPS calculations 4	3.3	3.2	0.5

1. Historical Dow restricted stock units are considered participating securities due to Historical Dow's practice of paying dividend equivalents on unvested shares.

2. Earnings per share amounts are computed independently for income from continuing operations, income from discontinued operations and net income attributable to common stockholders. As a result, the per share amounts from continuing operations and discontinued operations may not equal the total per share amounts for net income attributable to common stockholders.

3. As a result of the Merger, the share amounts for the year ended December 31, 2017 reflect a weighted averaging effect of Historical Dow shares outstanding prior to August 31, 2017 and DowDuPont shares outstanding on and after August 31, 2017.

4. These outstanding options to purchase shares of common stock and restricted stock units were excluded from the calculation of diluted earnings per share because the effect of including them would have been antidilutive.

Leases [Abstract]

Leases of Lessee Disclosure [Text Block]

LEASES

The Company has operating and finance leases for real estate, an airplane, railcars, fleet, certain machinery and equipment, and information technology assets. The Company’s leases have remaining lease terms of approximately 1 year to 40 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 is included in the related lease liability in the Consolidated Balance Sheet other than certain finance leases that include the maximum residual value guarantee amount in the measurement of the related liability given the election to use the package of practical expedients at the date of adoption. At December 31, 2019, the Company has future maximum payments for residual value guarantees in operating leases of $19 million with final expirations through 2031. The Company's lease agreements do not contain any material restrictive covenants.

The components of lease cost for operating and finance leases for the year ended December 31, 2019 were as follows:

In millions	2019
Operating lease cost	$	182

Operating lease ROU assets and lease 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.

Subsequent to the Distributions, the Company maintained an ownership interest in 22 nonconsolidated affiliates, with ownership interest (direct and indirect) ranging from 49 percent to 50.1 percent at December 31, 2019. The following table reflects the Company's principal nonconsolidated affiliates and its ownership interest (direct and indirect) for each at December 31, 2019:

	Country	Ownership Interest
		2019
The HSC Group:
DC HSC Holdings LLC 1	United States	50.0	%
Hemlock Semiconductor L.L.C.	United States	50.1	%

1. DC HSC Holdings LLC holds an 80.5 percent percent indirect ownership interest in Hemlock Semiconductor Operations LLC.

Sales to nonconsolidated affiliates represented less than 3 percent of total net sales for the year ended December 31, 2019 and 2018, and approximately 4 percent of total net sales for the year ended December 31, 2017. Sales to nonconsolidated affiliates are primarily related to the sale of trichlorosilane, a raw material used in the production of polycrystalline silicon, to the HSC Group. Sales of this raw material to the HSC Group are reflected in Non-Core. Purchases from nonconsolidated affiliates represented less than 2 percent of “Cost of sales” in 2019, 2018, and 2017.

HSC Group

The carrying value of the Company's investments in the HSC Group, which represents Hemlock Semiconductor L.L.C. and DC HSC Holdings LLC, was adjusted as a result of the HSC Group's adoption of Topic 606 on January 1, 2019 in accordance with the effective date of Topic 606 for non-public companies. The resulting impact to the Company's investments in the HSC Group was a reduction to "Investment in nonconsolidated affiliates" of $71 million and an increase to "Other noncurrent obligations" of $168 million, as well as an increase to "Deferred income tax assets" of $56 million and a reduction to "(Accumulated Deficit) Retained earnings" of $183 million in the Consolidated Balance Sheet at January 1, 2019.

The Company's investment in and equity earnings from the HSC Group are shown in the tables below:

STOCK-BASED COMPENSATION STOCK-BASED COMPENSATION (Notes)

Share-based Payment Arrangement [Abstract]

Share-based Payment Arrangement [Text Block]

STOCK-BASED COMPENSATION

On May 23, 2019, stockholders of DowDuPont approved a reverse stock split of DowDuPont shares of common stock. DowDuPont's Board of Directors established a reverse stock split ratio of 1 new share of DowDuPont common stock for every 3 shares of current DowDuPont common stock with par value of $0.01 per share. The stock split became effective immediately following the Corteva Distribution on June 1, 2019. All comparable periods presented have been retrospectively revised to reflect this change.

Effective with the Merger, on August 31, 2017, DowDuPont assumed all Historical Dow and Historical EID equity incentive compensation awards outstanding immediately prior to the Merger. The fair values of the converted awards were based on valuation assumptions developed by management and other information including, but not limited to, historical volatility and exercise trends of Historical Dow and Historical EID. All outstanding Historical Dow stock options and restricted stock unit ("RSU") (formerly termed deferred stock) awards were converted into stock options and RSU awards with respect to DowDuPont Common Stock. All outstanding and nonvested Historical Dow performance stock unit ("PSU") (formerly termed performance deferred stock) awards were converted into RSU awards with respect to DowDuPont Common Stock at the greater of the applicable performance target or the actual performance as of the effective time of the Merger.

In addition, the Company also assumed sponsorship of each equity incentive compensation plan of Historical Dow and Historical EID. Historical Dow and Historical EID did not merge their equity incentive plans as a result of the Merger. The Historical Dow and Historical EID stock-based compensation plans were assumed by DowDuPont and remained in place with the ability to grant and issue DowDuPont common stock until the Distributions. Immediately following the Corteva Distribution, DuPont adopted the DuPont Omnibus Incentive Plan ("DuPont OIP") which provides for equity-based and cash incentive awards to certain employees, directors, independent contractors and consultants. Upon adoption of the DuPont OIP, the Historical Dow and Historical EID plans were maintained and rolled into the DuPont OIP as separate subplans. The equity awards under these subplans have the same terms and conditions that were applicable to the awards under the Historical Dow and Historical EID plans immediately prior to the Distributions.

A description of the Company's stock-based compensation is discussed below followed by a description of Historical Dow and Historical EID stock-based compensation.

Accounting for Stock-Based Compensation

The Company grants stock-based compensation awards that vest over a specified period or upon employees meeting certain performance and/or retirement eligibility criteria. The fair value of equity instruments issued to employees is measured on the grant date. The fair value of liability instruments issued to employees is measured at the end of each quarter. The fair value of equity and liability instruments is expensed over the vesting period or, in the case of retirement, from the grant date to the date on which retirement eligibility provisions have been met and additional service is no longer required. The Company estimates expected forfeitures.

DuPont recognized share-based compensation expense in continuing operations of $106 million, $92 million and $19 million during the years ended December 31, 2019, 2018 and 2017, respectively. The income tax benefits related to stock-based compensation arrangements were $22 million, $19 million and $4 million for the years ended December 31, 2019, 2018 and 2017, respectively.

Total unrecognized pretax compensation cost related to nonvested stock option awards of $23 million at December 31, 2019, is expected to be recognized over a weighted-average period of 1.6 years. Total unrecognized pretax compensation cost related to RSUs and PSUs of $83 million at December 31, 2019, is expected to be recognized over a weighted average period of 2.0 years. The total fair value of RSUs and PSUs vested in the year ended December 31, 2019 was $37 million. The weighted average grant-date fair value of restricted stock units granted during 2019 was $72.67.

DuPont Omnibus Incentive Plan

The Company grants stock-based compensation awards to certain employees, directors, independent contractors and consultants in the form of stock incentive plans, which include stock options, RSUs and PSUs. The DuPont OIP has two subplans that have the same terms and conditions of the Historical Dow and Historical EID plans immediately prior to the Distributions. Awards previously granted under those plans that were nonvested will now vest in each subplan. All new awards will be granted by the OIP. Under the DuPont OIP, a maximum of 14 million shares of common stock may be awarded.

OIP 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. Stock option awards expire 10 years after the grant date. The plan allows retirement-eligible employees of the Company to retain any granted awards upon retirement provided the employee has rendered at least six months of service following the grant date.

The Company uses the Black-Scholes option pricing model to determine the fair value of stock option awards and the assumptions set forth in the table below. The weighted-average grant-date fair value of options granted for the year ended December 31, 2019. The weighted-average assumptions used to calculate total stock-based compensation are included in the following table:

OIP Weighted-Average Assumptions	2019
Dividend yield	1.8	%
Expected volatility	21.1	%
Risk-free interest rate	1.6	%
Expected life of stock options granted during period (years)	6.1

The Company determines the dividend yield by dividing the annualized dividend on DuPont's common stock by the option exercise price. A historical daily measurement of volatility (using DowDuPont stock information after the Merger date and a weighted average of Historical Dow and Historical EID prior to Merger date) is determined based on the expected life of the option granted. 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 DuPont's historical experience, adjusted for expected exercise patterns of in-the-money options.

The following table summarizes stock option activity for 2019 under the OIP:

OIP Stock Options	For the Year Ended December 31, 2019
	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, 2019	—		$	—

In millions, except per share amounts	2019
Weighted-average fair value per share of options granted	$	11.85
Total compensation expense for stock options plans	$	5
Related tax benefit	$	1

1. No awards have vested under the OIP as of December 31, 2019.

The aggregate intrinsic values in the table above represent the total pretax intrinsic value (the difference between the closing stock price on the last trading day of 2019 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 year end.

OIP Restricted Stock Units and Performance Deferred Stock

The Company grants RSUs to certain employees that serially vested over a three-year period and, upon vesting, convert one-for-one to DuPont 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. 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 under a subplan of the DuPont OIP. Vesting for PSUs granted is based upon achieving certain adjusted operating EBITDA targets and certain return on invested capital ("ROIC") targets, weighted evenly between the metrics. Performance and payouts are determined independently for each metric. The actual award, delivered as DuPont common stock, can range from zero percent to two-hundred percent of the original grant. The weighted-average grant-date fair value of the PSUs is based upon the market price of the underlying common stock as of the grant date.

Nonvested awards of RSUs and PSUs are shown below.

OIP RSUs and PSUs	2019
	Number of Shares (in thousands)		Weighted Average Grant Date Fair Value (per share)
Nonvested at January 1, 2019	—		$	—
Granted	566		$	66.55
Vested	—		$	—
Forfeited	(5	)	$	66.06
Nonvested at December 31, 2019	561		$	66.56

Historical Dow Plans

Historical Dow granted stock-based compensation to employees and non-employee directors in the form of stock incentive plans, which include stock options, RSUs and restricted stock. Historical Dow also provided stock-based compensation in the form of PSUs and the Employee Stock Purchase Plan ("ESPP"), which grants eligible employees the right to purchase shares of Historical Dow Common Stock at a discounted price.

Historical Dow Valuation Methods and Assumptions

Historical Dow previously used a lattice-based option valuation model to estimate the fair value of stock options and used a Monte Carlo simulation for the market portion of PSU awards. Effective with the first quarter of 2018 grant, Historical Dow began using the Black-Scholes option valuation model to estimate the fair value of stock options. This valuation methodology was adopted as a result of the Merger to align valuation methodologies with Historical EID and better align with industry practice. Historical Dow used the Black-Scholes option valuation model for subscriptions to purchase shares under the ESPP. The weighted-average assumptions used to calculate total stock-based compensation are included in the following table:

Historical Dow Weighted-Average Assumptions 1	2018		2017
Dividend yield	2.13	%	3.01	%
Expected volatility	23.34	%	23.71	%
Risk-free interest rate	2.83	%	1.28	%
Expected life of stock options granted during period (years)	6.2		7.5
Life of Employee Stock Purchase Plan (months)	—		3

1. No awards were granted by the Company out of the Historical Dow plan during 2019.

The dividend yield assumption was equal to the dividend yield on the grant date, which reflected the most recent DowDuPont quarterly dividend payment of $0.38 per share in 2018 ($0.46 per share in 2017 on Historical Dow Common Stock). The expected volatility assumptions for the 2017 stock options and ESPP were based on an equal weighting of the historical daily volatility for the contractual term of the awards and current implied volatility from exchange-traded options. The expected volatility assumptions for the 2018 stock options were based on an equal weighting of the historical daily volatility for the expected term of the awards and current implied volatility from exchange-traded options. The expected volatility assumption for the market portion of the 2017 PSU awards were based on historical daily volatility for the term of the award. The risk-free interest rate was based on the weighted-average of U.S. Treasury strip rates over the contractual term of the 2017 options. The risk-free interest rate was based on the

U.S. Treasury strip rates over the expected life of the 2018 options. The expected life of stock options granted was based on an analysis of historical exercise patterns.

Historical Dow Stock Incentive Plan

Historical Dow previously granted equity awards under various plans (the "Prior Plans"). On February 9, 2012, Historical Dow's Board of Directors authorized The Dow Chemical Company 2012 Stock Incentive Plan (the "2012 Plan"), which was approved by stockholders at Historical Dow's annual meeting on May 10, 2012 ("Original Effective Date") and became effective on that date. On February 13, 2014, Historical Dow's Board of Directors adopted The Dow Chemical Company Amended and Restated 2012 Stock Incentive Plan (the "2012 Restated Plan"). The 2012 Restated Plan was approved by stockholders at Historical Dow's annual meeting on May 15, 2014, and became effective on that date. The Prior Plans were superseded by the 2012 Plan and the 2012 Restated Plan (collectively, the "2012 Plan"). Under the 2012 Plan, Historical Dow may grant options, RSUs, PSUs, restricted stock, stock appreciation rights and stock units to employees and non-employee directors until the tenth anniversary of the Original Effective Date, subject to an aggregate limit and annual individual limits. The terms of the grants are fixed at the grant date. Historical Dow's stock-based compensation programs were assumed by DowDuPont and continue in place with the ability to grant and issue DowDuPont common stock.

In connection with the Merger, on August 31, 2017 ("Conversion Date") all outstanding Historical Dow stock options and RSU awards were converted into stock options and RSU awards with respect to DowDuPont Common Stock. The stock options and RSU awards have the same terms and conditions under the applicable plans and award agreements prior to the Merger. All outstanding and nonvested PSU awards were converted into RSU awards with respect to DowDuPont Common Stock at the greater of the applicable performance target or the actual performance as of the effective time of the Merger. Changes in the fair value of liability instruments are recognized as compensation expense each quarter. Upon the adoption of the OIP, the 2012 Plan became an inactive sub plan of the OIP and no longer grants new awards. All previously granted awards still vest under the 2012 Plan with the same terms and conditions that were applicable to the awards immediately prior to the Distributions.

Historical Dow Stock Options

Historical Dow granted stock options to certain employees, subject to certain annual and individual limits, with terms of the grants fixed at the grant date. The exercise price of each stock option equals the market price of Historical Dow’s stock on the grant date. Options vest from one year to three years, and had a maximum term of 10 years.

Total incremental pretax compensation expense resulting from the conversion of PSU awards into RSU awards was $25 million ($20 million was recognized in the second half of 2017 and $5 million to be recognized over the remaining service period). Approximately 5,000 employees were impacted by the conversion.

Historical Dow Performance Stock Units

Historical Dow granted performance stock units to certain employees. The grants vest when specified performance targets are attained, such as return on capital and relative total shareholder return, over a predetermined period, generally one year to three years. In November 2017, DowDuPont granted PSUs to senior leadership measured on the realization of cost savings in connection with cost synergy commitments, as well as the Company’s ability to complete the Intended Business Separations. Performance and payouts are determined independently for each metric. Compensation expense related to PSU awards is recognized over the lesser of the service or performance period. Changes in the fair value of liability instruments are recognized as compensation expense each quarter.

Historical Dow Restricted Stock

Under the 2012 Plan, Historical Dow had the option to grant shares (including options, stock appreciation rights, stock units and restricted stock) to non-employee directors over the 10-year duration of the program, subject to the plan's aggregate limit as well as annual individual limits. The restricted stock issued under this plan cannot be sold, assigned, pledged or otherwise transferred by the non-employee director, until retirement or termination of service to Historical Dow. The following table shows the restricted stock issued under this plan:

Historical Dow Employee Stock Purchase Plan

On February 9, 2012, Historical Dow's Board of Directors authorized The Dow Chemical Company 2012 Employee Stock Purchase Plan (the "2012 ESPP") which was approved by stockholders at Historical Dow’s annual meeting on May 10, 2012. When offered, most employees are eligible to purchase shares of common stock of Historical Dow valued at up to 10 percent of their annual base salary. The value is determined using the plan price multiplied by the number of shares subscribed to by the employee. The plan price of the stock is set at an amount equal to at least 85 percent of the fair market value (closing price) of the common stock on a date during the fourth quarter of the year prior to the offering, or the average fair market value (closing price) of the common stock over a period during the fourth quarter of the year prior to the offering, in each case, specified by Historical Dow's Executive Vice President of Human Resources. The last offering of Historical Dow's 2012 ESPP closed on July 15, 2017. The ESPP was not offered in 2019 or 2018 and no current offerings remain outstanding.

Historical EID Plans

Prior to the Merger, Historical EID provided share-based compensation to its employees through grants of stock options, RSUs and PSUs. Most of these awards have been granted annually in the first quarter of each calendar year. Subsequent to the Merger, DowDuPont assumed sponsorship of the equity incentive compensation plan of Historical EID.

Historical EID Equity Incentive Plan

Historical EID's Equity Incentive Plan ("Historical EID EIP"), as amended and restated effective August 31, 2017, provides for equity-based and cash incentive awards to certain employees, directors and consultants. Under the Historical EID EIP, the maximum number of shares reserved for the grant or settlement of awards was 110 million shares, provided that each share in excess of 30 million that was issued with respect to any award that was not an option or stock appreciation right be counted against the 110 million share limit as four and one-half shares. Historical EID satisfied stock option exercises and vesting of RSUs and PSUs with shares of DowDuPont Common Stock. Upon the adoption of the OIP, Historical EID EIP became an inactive sub plan of the OIP and no longer grants new awards. All previously granted awards still vest under the Historical EID EIP with the same terms and conditions that were applicable to the awards immediately prior to the Distributions.

Historical EID Stock Options

The exercise price of shares subject to option is equal to the market price of Historical EID's stock on the date of grant. When converted into the right to receive 1.282 shares of DowDuPont Common Stock, the exercise price was also adjusted by the 1.282 conversion factor. All options vest serially over a three-year period. Stock option awards granted between 2010 and 2015 expire seven years after the grant date and options granted between 2016 and 2018 expire ten years after the grant date. The plan allowed retirement-eligible employees of Historical EID to retain any granted awards upon retirement provided the employee has rendered at least six months of service following the grant date. The awards have the same terms and conditions as were applicable to such equity awards immediately prior to the Merger closing date.

Historical EID used the Black-Scholes option pricing model to determine the fair value of stock option awards and the assumptions set forth in the table below. The weighted-average grant-date fair value of options granted for the years ended December 31, 2019, December 31, 2018 and December 31, 2017 was $15.69, $15.46 and $28.56, respectively. The weighted-average assumptions used to calculate total stock-based compensation are included in the following table:

Historical EID Weighted-Average Assumptions	2019		2018		2017
Dividend yield	1.6	%	2.1	%	2.2	%
Expected volatility	19.8	%	23.3	%	23.59	%
Risk-free interest rate	2.4	%	2.8	%	2.1	%
Expected life of stock options granted during period (years)	6.1		6.2		7.2

Historical EID 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 (using DowDuPont stock information after the Merger date and a weighted average of Historical Dow and Historical EID prior to Merger date) is determined based on the expected life of the option granted. 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 Historical EID's historical experience, adjusted for expected exercise patterns of in-the-money options.

The following table summarizes stock option activity for 2019 under Historical EID's EIP:

Historical EID Stock Options	2019
	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, 2019	17,079		$	53.26

Historical EID RSUs and PSUs

Historical EID issued RSUs that serially vested over a three-year period and, upon vesting, convert one-for-one to DowDuPont 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 were also granted periodically to key senior management employees. These RSUs generally vested over periods ranging from three years to five 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 awards have the same terms and conditions as were applicable to such equity awards immediately prior to the Merger closing date.

Historical EID granted PSUs to senior leadership. Upon a change in control, Historical EID's EIP provisions required PSUs to be converted into RSUs based on the number of PSUs that would vest by assuming that target levels of performance are achieved. Service requirements for vesting in the RSUs replicate those inherent in the exchanged PSUs.

Vesting for PSUs granted in 2016 and for the period January 1 through August 31, 2017 is based upon total shareholder return ("TSR") relative to peer companies. Vesting for PSUs granted in 2015 is equally based upon change in operating net income relative to target and TSR relative to peer companies. Operating net income is net income attributable to Historical EID excluding income from discontinued operations after taxes, significant after-tax benefits (charges), and non-operating pension and other postretirement benefit costs. Performance and payouts are determined independently for each metric. The actual award, delivered as DowDuPont 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 for the period January 1 through August 31, 2017, subject to the TSR metric, was $91.56, and estimated using a Monte Carlo simulation. The weighted-average grant-date fair value of the PSUs, subject to the revenue metric, was based upon the market price of the underlying common stock as of the grant date.

In accordance with the DWDP Merger Agreement, PSUs converted to RSU awards based on an assessment of the underlying market conditions in the PSUs at the greater of target or actual performance levels as of the closing date. As the actual performance levels were not in excess of target as of the closing date, all PSUs converted to RSUs based on target and there was no incremental benefit from the DWDP Merger Agreement when compared with Historical EID’s EIP.

In November 2017, DowDuPont granted PSUs to senior leadership that vest partially based on the realization of cost savings in connection with cost synergy commitments, as well as DowDuPont’s ability to complete the Intended Business Separations. Performance and payouts are determined independently for each metric. The actual award, delivered in DowDuPont 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 November 2017 of $71.16 was based upon the market price of the underlying common stock as of the grant date. There were no PSUs granted in the years ended December 31, 2019 and December 31, 2018.

Nonvested awards of RSUs and PSUs are shown below.
