The Company's principal executive offices are located at 20302211 H.H. Dow Center,Way, Midland, Michigan 48674. Throughout this Annual Report on Form 10-K, except as otherwise indicated by the context, the terms “Company” or “Dow” as used herein mean The Dow Chemical Company and its consolidated subsidiaries.

Merger with DuPont
OnEffective 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, Dow and E. I. du Pont de Nemours and Company (“DuPont”("DuPont") entered into an Agreement and Plan of Merger, as amended on March 31, 2017 (the "Merger Agreement") to effect an all-stock, merger of equals strategic combination resulting in a newly formed corporation named DowDuPont Inc. ("DowDuPont"). On August 31, 2017, pursuant to the terms of the Merger Agreement, Dow and DuPont each merged with subsidiaries of DowDuPont (the "Mergers"Inc. ("DowDuPont") and, as a result, of the Mergers,Dow and DuPont became subsidiaries of DowDuPont (collectively,(the "Merger"). Following the "Merger"Merger, Dow and DuPont intend to pursue, subject to certain customary conditions, including, among others, the effectiveness of registration statements filed with the U.S. Securities and Exchange Commission ("SEC") and approval by the board of directors of DowDuPont, the separation of the combined company's agriculture, materials science and specialty products businesses through one or more tax-efficient transactions ("Intended Business Separations").

Effective with the Merger, Dow’s business activities are components of its parent company’s business operations. Dow’s business activities, including the assessment of performance and allocation of resources, ultimately are reviewed and managed by DowDuPont. Information used by the chief operating decision maker of Dow relates to the Company in its entirety. Accordingly, there are no separate reportable business segments for the Company under Accounting Standards Codification Topic 280 “Segment Reporting” and the Company’s business results are reported in this Form 10-K as a single operating segment.

Also effective withAs a result of the Merger, DowDuPont owns all of the common stock of Dow, and Dow has met the conditions set forth inDow. Pursuant to General InstructionsInstruction I(1)(a) and (b) of Form 10-K “Omission of Information by Certain Wholly-Owned Subsidiaries.Subsidiaries, As a result, the Company is filing this Form 10-K with a reduced disclosure format. In addition, the Company has elected to make certain changes in the presentation of its Consolidated Financial Statements and Notes to the Consolidated Financial Statements to conform with the presentation adopted for DowDuPont. See Note 13 to the Consolidated Financial Statements for further discussion of these changes and Note 3 for additional information on the Merger.

Intended Business Separations
In furtherance of the Intended Business Separations, Dow and DuPont are engaged in a series of internal reorganization and realignment steps (the “Internal Reorganization”) to realign their businesses into three subgroups: agriculture, materials science and specialty products. DowDuPont has also formed two wholly owned subsidiaries: Dow Holdings Inc. (“DHI”), 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. Following the separation and distribution of DHI, which is targeted to occur by April 1, 2019, DowDuPont, as the remaining company, which is referred to herein as “New DuPont,” will continue to hold the agriculture and specialty products businesses. New DuPont is then targeted to complete the separation and distribution of Corteva on June 1, 2019, resulting in New DuPont holding the specialty products businesses of DowDuPont. Following the distributions, DowDuPont will be known as DuPont.

As part of the Internal Reorganization, 1) the assets and liabilities of the materials science business will be transferred or conveyed to legal entities that then will be aligned under DHI, 2) the assets and liabilities of the agriculture business will be transferred or conveyed to legal entities that then will be aligned under Corteva, and 3) the assets and liabilities of the specialty products business will be transferred or conveyed to legal entities that then will be aligned with New DuPont. Following the Internal Reorganization, DowDuPont expects to distribute DHI and Corteva through separate, pro rata U.S. federal tax-free spin-offs in which DowDuPont stockholders, at such time, would receive shares of common stock of DHI and of Corteva.

Additional information is included in the Form 10 registration statements for the separation of DowDuPont's materials science business (filed as Dow Holdings Inc.) filed with the SEC on September 7, 2018, as amended on October 19, 2018 and November 19, 2018, and the agriculture business (filed as Corteva, Inc.) filed with the SEC on October 18, 2018, as amended on December 19, 2018.

ITEM 1A. RISK FACTORS
The factors described below represent the Company's principal risks.

Global Economic Considerations: The Company operates in a global, competitive environment which gives rise to operating and market risk exposure.
The Company sells its broad range of products and services in a competitive, global environment, and competes worldwide for sales on the basis of product quality, price, technology and customer service. Increased levels of competition could result in lower prices or lower sales volume, which could have a negative impact on the Company'sCompany’s results of operations. Sales of the Company'sDow’s products are also subject to extensive federal, state, local and foreign laws and regulations, trade agreements, import and export controls and duties and tariffs. The imposition of additional regulations, controls and duties and tariffs or changes to bilateral and regional trade agreements could result in lower sales volume, which could negatively impact the Company'sCompany’s results of operations.

Economic conditions around the world, and in certain industries in which the Company does business, also impact sales price and volume. As a result, market uncertainty or an economic downturn in the geographic regions or industries in which Dow sells its products could reduce demand for these products and result in decreased sales volume, which could have a negative impact on Dow'sthe Company’s results of operations.

In addition, volatility and disruption of financial markets could limit customers'customers’ ability to obtain adequate financing to maintain operations, which could result in a decrease in sales volume and have a negative impact on Dow'sthe Company’s results of operations. The Company'sDow’s global business operations also give rise to market risk exposure related to changes in foreign exchange rates, interest rates, commodity prices and other market factors such as equity prices. To manage such risks, Dow enters into hedging transactions pursuant to established guidelines and policies. If Dow fails to effectively manage such risks, it could have a negative impact on the Company'sCompany’s results of operations.

Financial Commitments and Credit Markets: Market conditions could reduce the Company's flexibility to respond to changing business conditions or fund capital needs.
Adverse economic conditions could reduce the Company'sCompany’s flexibility to respond to changing business and economic conditions or to fund capital expenditures or working capital needs. The economic environment could result in a contraction in the availability of credit in the marketplace and reduce sources of liquidity for the Company. This could result in higher borrowing costs.
Raw Materials: Availability of purchased feedstocksfeedstock and energy, and the volatility of these costs, impact Dow’s operating costs and add variability to earnings.
Purchased feedstock and energy costs account for a substantial portion of the Company’s total production costs and operating expenses. The Company purchases hydrocarbon raw materials including ethane, propane, butane, naphtha and condensate as feedstocks. The Companyfeedstocks and also purchases certain monomers, primarily ethylene and propylene, to supplement internal production, as well as other raw materials. The Company also purchases natural gas, primarily to generate electricity, and purchases electric power to supplement internal generation.

Feedstock and energy costs generally follow price trends in crude oil and natural gas, which are sometimes volatile.volatile. While the Company uses its feedstock flexibility and financial and physical hedging programs to help mitigate feedstock cost increases, the Company is not always able to immediately raise selling prices. Ultimately, the ability to pass on underlying cost increases is dependent on market conditions. Conversely, when feedstock and energy costs decline, selling prices generally decline as well. As a result, volatility in these costs could impact the Company’s results of operations.

The Company has a number of investments inon the U.S. Gulf Coast to take advantage of increasing supplies of low-cost natural gas and NGLsnatural gas liquids (“NGLs”) derived from shale gas including: the restart of the St. Charles Operations (SCO-2) ethylene production facility in December 2012; construction of a new on-purpose propylene production facility, which commenced operations in December 2015; completion of a major maintenance turnaround in December 2016 at an ethylene production facility in Plaquemine, Louisiana, which included expanding the facility’s ethylene production capacity by up to 250 kilotonnes per annum ("KTA") and modifications to enable full ethane cracking flexibility; and, constructioncompletion of a new integrated world-scale ethylene production facility and a new ELITE™ Enhanced Polyethylene production facility, both located in Freeport, Texas, which commenced operations in the third quarter of 2017, and a capacity expansion project which will bring the facility'sfacility’s total ethylene capacity to 2,000 KTA.kilotonnes per annum (“KTA”) by 2020; and, the Company commenced operations in 2018 on its new Low Density Polyethylene ("LDPE") production facility and its new NORDEL™ Metallocene EPDM production facility, both located in Plaquemine, Louisiana. As a result of these investments, the Company'sCompany’s exposure to purchased ethylene and propylene is expected to decline, offset by increased exposure to ethane- and propane-based feedstocks.

While the Company expects abundant and cost-advantaged supplies of NGLs in the United States to persist for the foreseeable future, if NGLs were to become significantly less advantaged than crude oil-based feedstocks, it could have a negative impact on the Company’s results of operations and future investments. Also, if the Company’s key suppliers of feedstocks and energy are unable to provide the raw materials required for production, it could have a negative impact on the Company'sCompany’s results of operations.

Supply/Demand Balance: Earnings generated by the Company's products vary based in part on the balance of supply relative to demand within the industry.
The balance of supply relative to demand within the industry may be significantly impacted by the addition of new capacity, especially for basic commodities where capacity is generally added in large increments as world-scale facilities are built. This may disrupt industry balances and result in downward pressure on prices due to the increase in supply, which could negatively impact the Company'sCompany’s results of operations.

Litigation: The Company is party to a number of claims and lawsuits arising out of the normal course of business with respect to product liability, patent infringement, employment matters, governmental tax and regulation disputes, contract and commercial litigation, and other actions.
Certain of the claims and lawsuits facing the Company purport to be class actions and seek damages in very large amounts. All such claims are contested. With the exception of the possible effect of the asbestos-related liability of Union Carbide Corporation (“Union Carbide”) and Chapter 11 related matters of Dow Silicones Corporation (“Dow Silicones,” formerly known as Dow Corning Corporation, ("Dow Corning")which changed its name effective as of February 1, 2018) as described below, it is the opinion of the Company'sCompany’s management that the possibility is remote that the aggregate of all such claims and lawsuits will have a material adverse impact on the Company'sCompany’s consolidated financial statements.

Union Carbide is and has been involved in a large number of asbestos-related suits filed primarily in state courts during the past four decades. At December 31, 2017,2018, Union Carbide's total asbestos-related liability, including future defense and processing costs, was $1,369$1,260 million ($1,4901,369 million at December 31, 2016)2017).

In 1995, Dow Corning,Silicones, a former 50:50 joint venture, voluntarily filed for protection under Chapter 11 of the U.S. Bankruptcy Code in order to resolve breast implant liabilities and related matters ("Chapter(the “Chapter 11 Proceeding"Proceeding”). Dow CorningSilicones emerged from the Chapter 11 Proceeding on June 1, 2004, and is implementing the Joint Plan of Reorganization (the "Plan"“Plan”). The Plan provides funding for the resolution of breast implant and other product liability litigation covered by the Chapter 11 Proceeding and provides a process for the satisfaction of commercial creditor claims in the Chapter 11 Proceeding. At December 31, 2017, Dow Corning'sSilicones’ liability for breast implant and other product liability claims was $263 million at December 31, 2018 ($263 million at December 31, 2016)2017) and the liability related to commercial creditor claims was $78$82 million ($10878 million at December 31, 2016)2017).

See Note 16 to the Consolidated Financial Statements for additional information on these matters.

Environmental Compliance: The costs of complying with evolving regulatory requirements could negatively impact the Company's financial results. Actual or alleged violations of environmental laws or permit requirements could result in restrictions or prohibitions on plant operations, substantial civil or criminal sanctions, as well as the assessment of strict liability and/or joint and several liability.
The Company is 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. At December 31, 2017,In addition, the Company had accrued obligations of $878 million ($909 million at December 31, 2016) for probablemay have costs related to environmental remediation and restoration costs, including $152 million ($151 million at December 31, 2016)obligations associated with past and current sites as well as related to the Company’s past or current waste disposal practices or other hazardous materials handling. Although management will estimate and accrue liabilities for the remediation of Superfund sites. 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, althoughthese obligations, it is reasonably possible that the Company’s ultimate cost with respect to these particular matters could range up to approximately two times that amount.be significantly higher, which could negatively impact the Company’s financial condition and results of operations. 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'sCompany’s operations, or require modifications to its facilities. Accordingly, environmental, health or safety regulatory matters could result in significant unanticipated costs or liabilities.

Health and Safety: Increased concerns regarding the safe use of chemicals and plastics in commerce and their potential impact on the environment as well as perceived impacts of plant biotechnology on health and the environment have resulted in more restrictive regulations and could lead to new regulations.
Concerns regarding the safe use of chemicals and plastics in commerce and their potential impact on health and the environment and the perceived impacts of plant biotechnology 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 and continued pressure for 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. In addition, terrorist attacks and natural disasters have increased concerns about the security and safety of chemical production and distribution. These concerns could have a negative impact on the Company's results of operations.

Local, state, federal and foreign governments continue to propose new regulations related to the security of chemical plant locations and the transportation of hazardous chemicals, which could result in higher operating costs.

Operational Event: A significant operational event could negatively impact the Company's results of operations.
As a diversified chemical manufacturing company, the Company's operations, the transportation of products, cyber-attacks, or severe weather conditions and other natural phenomena (such as freezing, drought, hurricanes, earthquakes, tsunamis, floods, etc.) could result in an unplanned event that could be significant in scale and could negatively impact operations, neighbors or the public at large, which could have a negative impact on the Company's results of operations.

Major hurricanes have caused significant disruption in Dow's operations on the U.S. Gulf Coast, logistics across the region, and the supply of certain raw materials, which had an adverse impact on volume and cost for some of Dow's products. Due to the Company's substantial presence on the U.S. Gulf Coast, similar severe weather conditions or other natural phenomena in the future could negatively impact Dow'sthe Company's results of operations.

Cyber Threat: The risk of loss of the Company’s intellectual property, trade secrets or other sensitive business information or disruption of operations could negatively impact the Company’s financial results.
Cyber-attacks or security breaches could compromise confidential, business critical information, cause a disruption in the Company’s operations or harm the Company's reputation. The Company has attractive information assets, including intellectual property, trade secrets and other sensitive, business critical information. While the Company has a comprehensive cyber-security program that is continuously reviewed, maintained and upgraded, a significant cyber-attack could result in the loss of critical business information and/or could negatively impact operations, which could have a negative impact on the Company’s financial results.

Company Strategy: Implementing certain elements of the Company's strategy could negatively impact the Company's financial results.
The Company currently has manufacturing operations, sales and marketing activities, and joint ventures as well as proposed and existing projects of varying size in emerging geographies. Activities in these geographic regions are accompanied by uncertainty and risks including: navigating different government regulatory environments; relationships with new, local partners; project funding commitments and guarantees; expropriation, military actions, war, terrorism and political instability; sabotage; uninsurable risks; suppliers not performing as expected resulting in increased risk of extended project timelines; and determining raw material supply and other details regarding product movement. If the manufacturing operations, sales and marketing activities, and/or implementation of these projects is not successful, it could adversely affect the Company'sCompany’s financial condition, cash flows and results of operations.

The Company has also announced a numberGoodwill: An impairment of portfolio management actions as part of Dow's ongoing strategic objectives, including changes to the Company's ownership interest in certain joint ventures. If the execution or implementation of these transactions is not successful, itgoodwill could adverselynegatively impact the Company'sDow’s financial condition, cash flows and results of operations.

An Impairment of Goodwill could Negatively Impact the Company's Financial Results.results.
At least annually, the Company assesses goodwill for impairment. If testing indicates that goodwill is impaired, the carrying value is written down based on fair value with a charge against earnings. Where the Company utilizes a discounted cash flow methodology in determining fair value, 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 could negatively impact the Company's results of operations. See Note 13 to the Consolidated Financial Statements for additional information regarding the Company's goodwill impairment testing.

Pension and Other Postretirement Benefits: Increased obligations and expenses related to the Company's defined benefit pension plans and other postretirement benefit plans could negatively impact Dow's financial condition and results of operations.
The Company has defined benefit pension plans and other postretirement benefit plans (the “plans”) in the United States and a number of other countries. The assets of the Company's funded plans are primarily invested in fixed income securities, equity securities of U.S. and foreign issuers and alternative investments, including investments in real estate, private equity limited partnershipsmarket securities and absolute return strategies. Changes in the market value of plan assets, investment returns, discount rates, mortality rates, regulations and the rate of increase in compensation levels may affect the funded status of the Company's plans and could cause volatility in the net periodic benefit cost, future funding requirements of the plans and the funded status of the plans. A significant increase in the Company's obligations or future funding requirements could have a negative impact on the Company's results of operations and cash flows for a particular period and on the Company's financial condition.

Intended Business Separations
In furtherance of the Intended Business Separations, Dow and DuPont are engaged in a series of internal reorganization and realignment steps (the “Internal Reorganization”) to realign their businesses into three subgroups: agriculture, materials science and specialty products. DowDuPont has also formed two wholly owned subsidiaries: Dow Holdings Inc. (“DHI”), 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. Following the separation and distribution of DHI, which is targeted to occur by April 1, 2019, DowDuPont, as the remaining company, which is referred to herein as “New DuPont,” will continue to hold the agriculture and specialty products businesses. New DuPont is then targeted to complete the separation and distribution of Corteva on June 1, 2019, resulting in New DuPont holding the specialty products businesses of DowDuPont. Following the distributions, DowDuPont will be known as DuPont.

As part of the Internal Reorganization, 1) the assets and liabilities of the materials science business will be transferred or conveyed to legal entities that then will be aligned under DHI, 2) the assets and liabilities of the agriculture business will be transferred or conveyed to legal entities that then will be aligned under Corteva, and 3) the assets and liabilities of the specialty products business will be transferred or conveyed to legal entities that then will be aligned with New DuPont. Following the Internal Reorganization, DowDuPont expects to distribute DHI and Corteva through separate, pro rata U.S. federal tax-free spin-offs in which DowDuPont stockholders, at such time, would receive shares of common stock of DHI and of Corteva.

Additional information is included in the Form 10 registration statements for the separation of DowDuPont's materials science business (filed as Dow Holdings Inc.) filed with the SEC on September 7, 2018, as amended on October 19, 2018 and November 19, 2018, and the agriculture business (filed as Corteva, Inc.) filed with the SEC on October 18, 2018, as amended on December 19, 2018.

Impact From Recently Enacted Tariffs

Interest expense and amortization of debt discount in 2017 was up from $858 million in 2016, primarily reflecting the effect of the long-term debt assumed in the Dow CorningSilicones ownership restructure. Interest expense and amortization of debt discount in 2016 was down from $946 million in 2015, primarily due to the impact of approximately $2.5 billion of debt retired in 2015. See Liquidity and Capital Resources in Management's Discussion and Analysis of Financial Condition and Results of Operations and NoteNotes 11 and 15 to the Consolidated Financial Statements for additional information related to debt financing activity.

Provision for Income Taxes
The Company's effective tax rate fluctuates based on, among other factors, where income is earned, reinvestment assertions regarding foreign income and the level of income relative to tax credits available. The Company's tax rate is also influenced byattributes and the level of equity earnings, since most of the earnings from the Company's equity method investments are taxed at the joint venture level. The underlying factors affecting the Company's overall tax rate are summarized in Note 9 to the Consolidated Financial Statements.

On December 22, 2017, the Tax Cuts and Jobs Act (“The Act”) was enacted. The Act reduces the U.S. federal corporate income tax rate from 35 percent to 21 percent, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously deferred, creates new provisions related to foreign sourced earnings, eliminates the domestic manufacturing deduction and moves to a hybrid territorial system. At December 31, 2017, the Company had not completed its accounting for the tax effects of The Act; however, the Company made a reasonable estimate of the effects on its existing deferred tax balances which resulted in a provisional charge of $50 million to "Provision for income taxes," and the one-time transition tax. In accordance with Staff Accounting Bulletin 118 ("SAB 118"), income tax which resulted in a provisional chargeeffects of $865 million to "ProvisionThe Act were

The Company expects that it will have sufficient foreign tax credits available to offset the tax liability associated with the one-time transition tax. See Note 9 to the Consolidated Financial Statements for additional information.effects of The Act.

The provision for income taxes was $1,285 million in 2018, compared with $2,204 million in 2017 up fromand $9 million in 20162016. The effective tax rate for 2018 was favorably impacted by the reduced U.S. federal corporate income tax rate as a result of The Act and $2,147 millionbenefits related to the issuance of stock-based compensation and unfavorably impacted by non-deductible restructuring costs and increases in 2015. statutory income in Latin America and Canada due to local currency devaluations. These factors resulted in an effective tax rate of 21.7 percent in 2018.

The tax rate for 2017 was unfavorably impacted by the enactment of The Act, the impairment of goodwill for which there was no corresponding tax deduction, charges related to tax attributes in the United States and Germany as a result of the Merger and certain non-deductible costs associated with the Merger. The tax rate was favorably impacted by the geographic mix of earnings, and the adoption of Accounting Standards Update ("ASU") 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting," which resulted in the recognition of excess tax benefits related to equitythe issuance of stock-based compensation in the provision for income taxes. These factors resulted in an effective tax rate of 78.7 percent for 2017. See Notes 1 and 9 to the Consolidated Financial Statements for additional information.

The tax rate for 2016 was favorably impacted by the non-taxable gain on the Dow CorningSilicones ownership restructure and a tax benefit on the reassessment of a deferred tax liability related to the basis difference in the Company’s investment in Dow Corning.Silicones. The tax rate was also favorably impacted by the geographic mix of earnings, the availability of foreign tax credits, and the deductibility of the urethane matters class action lawsuit and opt-out cases settlements, and the asbestos-related charge. A reduction in equity earnings and non-deductible costs associated with transactions and productivity actions unfavorably impacted the tax rate. These factors resulted in an effective tax rate of 0.2 percent for 2016.

The tax rate for 2015 was favorably impacted by portfolio actions, specifically the tax-efficient split-off of the Company's chlorine value chain, the non-taxable gain from the Univation step acquisition, and the sale of MEGlobal. The geographic mix of earnings favorably impacted the tax rate with the gain from the ANGUS Chemical Company divestiture and continued profitability improvement in Europe and Asia Pacific providing most of the benefit. The tax rate was unfavorably impacted by foreign subsidiaries repatriating cash to the United States, which was primarily derived from divestiture proceeds. Reduced equity earnings and continued increases in statutory income in Latin America and Canada due to local currency devaluations also unfavorably impacted the tax rate. These factors resulted in an effective tax rate of 21.6 percent for 2015.

Net Income Attributable to Noncontrolling Interests
Net income attributable to noncontrolling interests was $134 million in 2018, $129 million in 2017 and $86 million in 2016 and $98 million2016. Net income attributable to noncontrolling interests increased in 2015.2018 compared with 2017, primarily due to the sale of the Company's ownership interests in the SKC Haas Display Films group of companies. Net income attributable to noncontrolling interests increased in 2017 compared with 2016, primarily due to higher earnings from Dow Corning'sSilicones' consolidated joint ventures and improved results from a cogeneration facility in Brazil. Net income attributable to noncontrolling interests decreased in 2016 compared with 2015, primarily due to losses incurred by a cogeneration facility in Brazil, which more than offset the addition of earnings from Dow Corning's consolidated joint ventures. In addition, 2015 was also impacted by noncontrolling interests' portion of the 2015 restructuring charge. See Notes 6, 18 and 23 to the Consolidated Financial Statements for additional information.

Preferred Stock Dividends
On December 30, 2016, the Company converted all outstanding shares of its Cumulative Convertible Perpetual Preferred Stock, Series A ("Preferred Stock") into shares of the Company's common stock. As a result of this conversion, no shares of Preferred Stock are issued or outstanding. On January 6, 2017, the Company filed an amendment to its Restated Certificate of Incorporation by way of a certificate of elimination with the Secretary of State of Delaware eliminating this series of preferred stock. Preferred Stock dividends of $340 million were recognized in 2016 and 2015.2016. See Note 17 to the Consolidated Financial Statements for additional information.

Net Income Available for the Common StockholdersStockholder
Net income available for the common stockholdersstockholder was $4,499 million in 2018, compared with $466 million in 2017 compared withand $3,978 million in 2016 and $7,345 million in 2015.2016. Effective with the Merger, Dow no longer has publicly traded common stock. Dow's common shares are owned solely by its parent company, DowDuPont.

LIQUIDITY AND CAPITAL RESOURCES
The Company had cash and cash equivalents of $2,669 million at December 31, 2018 and $6,188 million at December 31, 2017, and $6,607of which $1,963 million at December 31, 2016, of which2018 and $4,318 million at December 31, 2017, and $4,890 million at December 31, 2016 was 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.

The Company has completed its evaluation of the impact of The Act requires the Companyon its permanent reinvestment assertion. The Act required companies to pay a one-time transition tax on the earnings of foreign subsidiaries, a portionmajority of which were previously considered permanently reinvested by the CompanyCompany. A tax liability was accrued for the estimated U.S. federal tax on all unrepatriated earnings at December 31, 2017, with further refinement during the 2018 measurement period, in accordance with The Act. The cumulative effect at December 31, 2018, was a charge of $780 million to "Provision for income taxes" in the consolidated statements of income, of which the full amount was covered by tax attributes (see Note 9 to the Consolidated Financial Statements for additionalfurther details onof The Act).

See Notes 1 and 2 to the Consolidated Financial Statements for additional information.

Cash Flows from Operating Activities
Cash provided by operating activities decreasedincreased in 2018 compared with 2017, primarily due to the change in the Company's accounts receivable securitization facilities discussed on the following page, a decrease in cash used for working capital requirements and higher cash earnings, which were partially offset by the absence of certain cash receipts in 2017. Cash used for operating activities increased in 2017 compared with 2016, primarily due to a reductionan increase in balances in the Company's accounts receivable securitization facilities, increasedcash used for working capital requirements, higher pension contributions resulting from a change in control provision in a non-qualified U.S. pension plan, higher integration and separation costs and a cash payment related to the Bayer CropScience arbitration matter, partially offset by a one-time cash receipt related to the Nova patent infringement award and advanced payments from customers for long-term ethylene supply agreements. Cash provided by operating activities decreased in 2016 compared with 2015, primarily due to cash payments related to the settlement of the urethane matters class action lawsuit and opt-out cases, increased integration and separation costs, a cash payment related to the settlement of an uncertain tax position and a one-time payment related to the termination of a terminal use agreement.

Cash Flows from Investing Activities
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 primarily forfrom proceeds from interests in trade accounts receivable conduits, proceeds from sales and maturities of investments and proceeds from divestitures, including the divestitures of the DAS Divested Ag Business and the EAA Business, which were partially offset by capital expenditures, purchases of investments and investments in and loans to nonconsolidated affiliates, primarily with Sadara, which were partially offsetSadara. Cash provided by proceeds from sales of investments and divestitures, including the divestitures of the DAS Divested Ag Business and the EAA Business. Cash used for investing activities in 2016 was primarily forfrom proceeds from interests in trade accounts receivable conduits and net cash acquired in the Dow Silicones ownership restructure, which were partially offset by capital expenditures as well asand investments in and loans to nonconsolidated affiliates, primarily with Sadara, which were partially offset by net cash acquired in the Dow Corning ownership restructure. Cash used for investing activities in 2015 was primarily for capital expenditures; purchases of investments, including the repayment of outstanding loans issued under company-owned life insurance policies; and investments in and loans made to nonconsolidated affiliates, primarily with Sadara. This was partially offset by proceeds received from divestitures, including the divestitures of ANGUS Chemical Company and the AgroFresh business, proceeds from the sale of the Company's interest in MEGlobal and proceeds from sales and maturities of investments.

In 2018, the Company entered into a shareholder loan reduction agreement with Sadara and converted $312 million of the remaining loan and accrued interest balance into equity. The Company's note receivable from Sadara was zero at December 31, 2018. In addition, in the fourth quarter of 2018, the Company waived $70 million of accounts receivable with Sadara, which was converted into equity. In 2017, the Company loaned $735 million to Sadara and converted $718 million to equity. The Companyinto equity, and had a note receivable from Sadara of $275 million at December 31, 2017. The Company loaned $1,015 million to Sadara and converted $1,230 million to equity during 2016, and had a note receivable from Sadara of $258 million at December 31, 2016. All or a portion of the outstanding loan to Sadara could potentially be converted to equity in future periods. The Company expects to loan between zero and $200up to $500 million to Sadara in 2018.2019. See Note 12 to the Consolidated Financial Statements for additional information.

On August 28, 2017, Dow and Saudi Aramco announced a non-binding Memorandum

Table of Understanding that sets forth a process for Dow to acquire an additional 15 percent ownership interest in Sadara from Saudi Aramco. The current equity ownership split is 65 percent Saudi Aramco and 35 percent Dow. If the potential transaction is concluded as presently proposed, Dow and Saudi Aramco would each hold a 50 percent equity stake in Sadara.Contents


The Company's capital expenditures, including capital expenditures of consolidated variable interest entities, were $2,538 million in 2018, $3,144 million in 2017 and $3,804 million in 2016 and $3,703 million in 2015.2016. The Company expects capital spending in 20182019 to be approximately $3.0$2.5 billion, to $3.2 billion, commensurate withbelow depreciation and amortization expense. In addition, the Company expects an additional $100 million to $200 millionexpense and inclusive of capital spending for targeted cost synergy and business separation projects.

Capital spending in 2018, 2017 2016 and 20152016 included spending related to certain U.S. Gulf Coast investment projects including: an on-purpose propylene production facility, which commenced operations in December 2015; a world-scale ethylene production facility and an ELITE™ polymerEnhanced Polyethylene production facility, both of which commenced operations in September 2017; a NORDEL™

Cash Flows from Financing Activities
Cash used for financing activities in 2018 included dividends paid to DowDuPont and payments of long-term debt, which were partially offset by proceeds from issuance of long-term debt. Cash used for financing activities in 2017 included dividends paid to stockholders through the close of the Merger, a dividend paid to the Company's parent, DowDuPont in the fourth quarter of 2017, and payments of long-term debt. Cash used for financing activities in 2016 included dividends paid to stockholders (including the accelerated payment of the fourth quarter preferred dividend), repurchases of common stock and payments of long-term debt. Cash used for financing activities in 2015 included dividends paid to stockholders, repurchases of common stock and payments of long-term debt, including the early redemption of InterNotes which was partially offset by proceeds from the issuance of long-term debt, including debt related to the split-off of the chlorine value chain. See Notes 7, 15 and 17 to the Consolidated Financial Statements for additional information related to the split-off of the chlorine value chain, the issuance orand retirement of debt and the Company's share repurchases and dividends.

Reclassification of Prior Year Amounts Related to Accounts Receivable Securitization
In connection with the review and implementation of ASU 2016-15 and additional interpretive guidance from the SEC related to the required method for calculating the cash received from beneficial interests in trade accounts receivable conduits, the Company changed the prior year presentation and amount of proceeds from interests in trade accounts receivable conduits. Changes related to the calculation and presentation of proceeds from interests in trade accounts receivable conduits resulted in a reclassification from cash used for operating activities to cash provided by investing activities of $9,462 million in 2017 and $8,551 million in 2016. In the fourth quarter of 2017, the Company suspended further sales of trade accounts receivable through these facilities and began reducing outstanding balances through collections of trade accounts receivable previously sold to such conduits. In September and October 2018, the North American and European facilities, respectively, were amended and the terms of the agreements changed from off-balance sheet arrangements to secured borrowing arrangements.

The following table reconciles cash flows from operating activities to a non-GAAP measure regarding cash flows from operating activities excluding the impact of ASU 2016-15 and related interpretive guidance for the years ended December 31, 2018, 2017 and 2016. Management believes this non-GAAP financial measure is relevant and meaningful as it presents cash flows from operating activities inclusive of all trade accounts receivable collection activity, which the Company utilizes in support of its operating activities.

Liquidity & Financial Flexibility
The Company’s primary source of incremental liquidity is cash provided byflows from operating activities. The generation of cash from operations and the Company's ability to access debt markets is expected to meet the Company’s cash requirements for working capital, capital expenditures, debt maturities, contributions to pension plans, dividend distributions to its parent company and other needs. In addition to cash provided byfrom operating activities, the Company’s current liquidity sources also include U.S. and Euromarket commercial paper, committed credit facilities, accounts receivable securitization facilities and other debt markets. Additional details on sources of liquidity are as follows:

Commercial Paper
Dow issues promissory notes under its U.S. and Euromarket commercial paper programs. The Company had $231$10 million of commercial paper outstanding at December 31, 2017 (zero2018 ($231 million at December 31, 2016)2017). The Company maintains access to the commercial paper market at competitive rates. Amounts outstanding under the Company's commercial paper programs during the period may be greater, or less than, the amount reported at the end of the period. Subsequent to December 31, 2017,2018, the Company issued approximately $700 million$1.6 billion of commercial paper that remains outstanding at February 15, 2018.paper.

Committed Credit Facilities
In the event Dow has short-term liquidity needs and is unable to issue commercial paper for any reason, Dow has the ability to access liquidity through its committed and available credit facilities. At December 31, 2017,2018, the Company had total committed credit facilities of $10.9$12.1 billion and available credit facilities of $6.4$7.6 billion. See Note 15 to the Consolidated Financial Statements for additional information on committed and available credit facilities.

In connection with the Dow Corning ownership restructure, on May 31, 2016, Dow Corning incurred $4.5 billion of indebtedness under a certain third party credit agreement ("DCC Term Loan Facility"). The Company subsequently guaranteed the obligations of Dow Corning under the DCC Term Loan Facility and, as a result, the covenants and events of default applicable to the DCC Term Loan Facility are substantially similar to the covenants and events of default set forth in the Company's Five Year Competitive Advance and Revolving Credit Facility. In the second quarter of 2017, Dow Corning exercised a 364-day extension option making amounts borrowed under the DCC Term Loan Facility repayable on May 29, 2018, and amended the DCC Term Loan Facility to include an additional 19-month extension option, at Dow Corning's election, upon satisfaction of certain customary conditions precedent. On February 8, 2018, Dow Corning delivered a notice of intent to exercise the 19-month extension option on the DCC Term Loan Facility.

Uncommitted Credit Facilities and Outstanding Letters of Credit
The Company had uncommitted credit facilities in the form of unused bank credit lines of approximately $2,853$3,480 million at December 31, 2017.2018. These lines can be used to support short-term liquidity needs and general purposes, including letters of credit. Outstanding letters of credit were $433$439 million at December 31, 2017.2018 ($433 million at December 31, 2017). These letters of credit support commitments made in the ordinary course of business.

Accounts Receivable Securitization Facilities
The Company has access to committed accounts receivable securitization facilities in the United States and Europe, from which amounts available for funding are based upon available and eligible accounts receivable within each of the facilities. The Company renewed the United States facility in June 2015 for a term that extends to June 2018. The Europe facility was renewed in July 2015 for a term that extends to July 2018.

In the fourth quarter of 2017, the Company suspended further sales of trade accounts receivable through these facilities and began reducing outstanding balances under these facilities through collections of trade accounts receivable previously sold to such

conduits. The Company has the ability to resume such sales to the conduits, subject to certain prior notice requirements, at the discretion of the Company. See Note 14 to the Consolidated Financial Statements for further information.

Debt
As Dow continues to maintain its strong balance sheet and financial flexibility, management is focused on net debt (a non-GAAP financial measure), as Dow believes this is the best representation of the Company’s financial leverage at this point in time. As shown in the following table, net debt is equal to total gross debt minus "Cash and cash equivalents" and "Marketable securities." At December 31, 2017,2018, net debt as a percent of total capitalization increased to 35.438.0 percent, compared with 35.135.4 percent at December 31, 2016.2017, primarily due to a decrease in cash and cash equivalents, which more than offset a decrease in gross debt.

In the fourth quarter of 2018, the Company issued $2.0 billion of senior unsecured notes in an offering under Rule 144A of the Securities Act of 1933, which included $500 million due 2025; $600 million due 2028 and $900 million due 2048. See Note 15 to the Consolidated Financial Statements for additional information on the interest related to these notes. In addition, the Company tendered and redeemed $2.1 billion of notes issued with maturity in 2019. In addition, DHI, the intended parent of the Company after the Intended Business Separations, is obligated, should it issue a guarantee in respect of outstanding or committed indebtedness under Dow’s Five Year Competitive Advance and Revolving Credit Facility Agreement (“Revolving Credit Agreement”), dated October 30, 2018, (as described below), to enter into a supplemental indenture with the Company and the trustee under the existing base indenture governing certain notes issued by the Company under which it will guarantee all outstanding debt securities and all amounts due under the existing base indenture.

Table of Contents


Dow’s public debt instruments and primary, private credit agreements contain, among other provisions, certain customary restrictive covenant and default provisions. The Company’s most significant debt covenant with regard to its financial position is the obligation to maintain the ratio of the Company’s consolidated indebtedness to consolidated capitalization at no greater than 0.65 to 1.00 at any time the aggregate outstanding amount of loans under the Five Year Competitive Advance and Revolving Credit Facility Agreement equals or exceeds $500 million. The ratio of the Company’s consolidated indebtedness to consolidated capitalization as defined in the Five Year Competitive Advance and Revolving Credit Facility Agreementwas 0.430.41 to 1.00 at December 31, 2017.2018. Management believes the Company was in compliance with all of its covenants and default provisions at December 31, 2017.2018. See Note 15 to the Consolidated Financial Statements for information related to the Company’s notes payable and long-term debt activity and information on Dow’s covenants and default provisions.

On October 30, 2018, Dow terminated and replaced its $5.0 billion Revolving Credit Agreement, under substantially similar terms and conditions. The new Revolving Credit Agreement has a maturity date in October 2023. The Revolving Credit Agreement includes an event of default which would be triggered in the event DHI incurs or guarantees third party indebtedness for borrowed money in excess of $250 million or engages in any material business activity or directly owns any material assets, in each case, subject to certain conditions and exceptions. DHI may, at its option, cure the event of default by delivering an unconditional and irrevocable guaranty to the administrative agent within thirty days of the event or events giving rise to such event of default.

Management expects that the Company will continue to have sufficient liquidity and financial flexibility to meet all of its business obligations.

Credit Ratings
TheAt January 31, 2019, the Company's credit ratings arewere as follows:

Pension Plans
The Company has defined benefit pension plans in the United States and a number of other countries. The Company’s funding policy is to contribute to plans when pension laws and/or economics either require or encourage funding. In 2018, 2017 2016 and 2015,2016, the Company contributed $1,656 million, $1,676 million $629 million and $844$629 million to its pension plans, respectively, including contributions to fund benefit payments for its non-qualified pension plans. Dow expects to contribute approximately $500In the third quarter of 2018, the Company made a $1,100 million discretionary contribution to its principal U.S. pension plan, which is included in the 2018 contribution amount above. The discretionary contribution was primarily based on the Company's funding policy, which permits contributions to defined benefit pension plans in 2018.when economics encourage funding, and reflected considerations relating to tax deductibility and capital structure.

The provisions of a U.S. non-qualified pension plan require the payment of plan obligations to certain participants upon a change in control of the Company, which occurred at the time of the Merger. Certain participants could elect to receive a lump-sum payment or direct the Company to purchase an annuity on their behalf using the after-tax proceeds of the lump sum. In the fourth quarter of 2017, the Company paid $940 million to plan participants and $230 million to an insurance company for the purchase of annuities, which were included in "Pension contributions" in the consolidated statements of cash flows. The Company also paid $205 million for income and payroll taxes for participants electing the annuity option. The Company recorded a settlement charge of $687 million associated with the payout in the fourth quarter of 2017.

Dow expects to contribute approximately $240 million to its pension plans in 2019. See Note 19 to the Consolidated Financial Statements for additional information concerning the Company’s pension plans.

Restructuring
The activities related to the SynergyDowDuPont Agriculture Division Program and the 2016 restructuring planSynergy Program are expected to result in additional cash expenditures of approximately $830$480 million to $900$510 million, primarily through September 30,the end of 2019, consisting of severance and related benefit costs and costs associated with exit and disposal activities, including environmental remediation (see Note 67 to the Consolidated Financial Statements). The Company expects to incur additional costs in the future related to its restructuring activities. Future costs are expected to include demolition costs related to closed facilities and restructuring plan implementation costs; these costs will be recognized as incurred. The Company also expects to incur additional employee-related costs, including involuntary termination benefits, related to its other optimization activities. These costs cannot be reasonably estimated at this time.

The Company expects to meet its contractual obligations through its normal sources of liquidity and believes it has the financial resources to satisfy these contractual obligations.

Off-Balance Sheet Arrangements
Off-balance sheet arrangements are obligations the Company has with nonconsolidated entities related to transactions, agreements or other contractual arrangements. The Company holds variable interests in joint ventures accounted for under the equity method of accounting. The Company is not the primary beneficiary of these joint ventures and therefore is not required to consolidate thethese entities (see Note 23 to the Consolidated Financial Statements). In addition, see Note 14 to the Consolidated Financial Statements for information regarding the transfer of financial assets.

Guarantees arise during 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. The Company had outstanding guarantees at December 31, 20172018 of $5,663$5,408 million, compared with $6,043$5,663 million at December 31, 2016.2017. Additional information related to guarantees can be found in the “Guarantees” section of Note 16 to the Consolidated Financial Statements.

Fair Value Measurements
See Note 19 to the Consolidated Financial Statements for information related to fair value measurements of pension and other postretirement benefit plan assets; see Note 21 for information related to other-than-temporary impairments; and, see Note 22 for additional information concerning fair value measurements, including the Company’s interests held in trade receivable conduits.measurements.

Critical Accounting Estimates
The preparation of financial statements and related disclosures in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make judgments, assumptions and estimates that affect the amounts reported in the consolidated financial statements and accompanying notes. Note 1 to the Consolidated Financial Statements describes the significant accounting policies and methods used in the preparation of the consolidated financial statements. Following are the Company’s accounting policies impacted by judgments, assumptions and estimates:

Litigation
The Company is subject to legal proceedings and claims arising out of the normal course of business including product liability, patent infringement, employment matters, governmental tax and regulation disputes, contract and commercial litigation and other actions. The Company routinely assesses the legal and factual circumstances of each matter, the likelihood of any adverse outcomes to these matters, as well as ranges of probable losses. A determination of the amount of the reserves required, if any, for these contingencies is made after thoughtful analysis of each known claim. Dow has an active risk management program consisting of numerous insurance policies secured from many carriers covering various timeframes. These policies may provide coverage that could be utilized to minimize the financial impact, if any, of certain contingencies. The required reserves may change in the future due to new developments in each matter. For further discussion, see Note 16 to the Consolidated Financial Statements.

Asbestos-Related Matters of Union Carbide Corporation
Union Carbide is and has been involved in a large number of asbestos-related suits filed primarily in state courts during the past four decades. These suits principally allege personal injury resulting from exposure to asbestos-containing products and frequently seek both actual and punitive damages. The alleged claims primarily relate to products that Union Carbide sold in the past, alleged exposure to asbestos-containing products located on Union Carbide’s premises, and Union Carbide’s responsibility for asbestos suits filed against a former Union Carbide subsidiary, Amchem Products, Inc. Each year, Ankura Consulting Group, LLC ("Ankura") performs a review for Union Carbide based upon historical asbestos claims, resolution and historical defense spending. Union Carbide compares current asbestos claim, resolution and defense spending activity to the results of the most recent Ankura study at each balance sheet date to determine whether the asbestos-related liability continues to be appropriate.

In 2016, the Company elected to change its method of accounting for Union Carbide's asbestos-related defense and processing costs from expensing as incurred to estimating and accruing a liability. In addition to performing their annual review of pending and future asbestos claim resolution activity, Ankura also performed a review of Union Carbide's asbestos-related defense and processing costs to determine a reasonable estimate of future defense and processing costs to be included in the asbestos-related liability, through the terminal year of 2049.

Environmental Matters
The Company determines the costs of environmental remediation of its facilities and formerly owned facilities based on evaluations of current law and existing technologies. Inherent uncertainties exist in such evaluations primarily due to unknown environmental conditions, changing governmental regulations and legal standards regarding liability, and emerging remediation technologies. The recorded liabilities are adjusted periodically as remediation efforts progress, or as additional technical or legal information becomes available. At December 31, 2017,2018, the Company had accrued obligations of $878$820 million for probable environmental remediation and restoration costs, including $152$156 million for the remediation of Superfund sites. 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 approximately two times that amount. For further discussion, see Environmental Matters in Management’s Discussion and Analysis of Financial Condition and Results of Operations and Notes 1 and 16 to the Consolidated Financial Statements.

Goodwill
In the fourth quarter of 2017, the Company early adopted ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment," as part of the annual goodwill impairment testing. See Note 2 to the Consolidated Financial Statements for additional information.
The Company performs goodwill impairment testing at the reporting unit level. Reporting units are the level at which discrete financial information is available and reviewed by business management on a regular basis. The Company tests goodwill for impairment annually (in the fourth quarter), or more frequently when events or changes in circumstances indicate it is more likely than not that the fair value of a reporting unit has declined below its carrying value. Goodwill is evaluated for impairment using qualitative and/or quantitative testing procedures. At December 31, 2017,2018, the Company has defined 1412 reporting units; goodwill is carried by all of these reporting units.
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 hydrocarbon and energy 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 estimated fair value of a reporting unit is less than its carrying value, additional quantitative testing is required.
Quantitative testing requires the fair value of the reporting unit to be compared with its carrying value. If the reporting unit's carrying value exceeds its fair value, an impairment charge is recognized for the difference. The Company utilizes a discounted cash flow methodology to calculate the fair value of its reporting units. This valuation technique has been selected by management as the most meaningful valuation method due to the limited number of market comparables for the Company's reporting units. However, where market comparables are available, the Company includes EBIT/EBITDA multiples as part of the reporting unit valuation analysis. The discounted cash flow valuations are completed using the following key assumptions (including certain ranges used for the 2017 testing):assumptions: projected revenue growth rates or compounded annual growth rates, over a ten-year cash flow forecast period, which ranged from 0.5 percent to 6.4 percent and varied by reporting unit based on underlying business fundamentals and future expectations; discount rates, which ranged from 7.2 percent to 9.1 percent; tax rates;rates, terminal values, differentiated based on the cash flow projection of each reporting unit and the projected net operating profit after tax ("NOPAT") growth rate, which ranged from 0.5 percent to 3.0 percent; currency exchange rates;rates, and forecasted long-term hydrocarbon and energy prices, by geographic area and by year, which includedinclude the Company's key feedstocks as well as natural gas and crude oil (due to its correlation to naphtha). Currency exchange rates and long-term hydrocarbon and energy prices are established for the Company as a whole and applied consistently to all reporting units, while revenue growth rates, discount rates and tax rates are established by reporting unit to account for differences in business fundamentals and industry risk.
20172018 Goodwill Impairment Testing
Effective with the Merger, the Company updated its reporting units to align with the level at which discrete financial information is available for review by management. A relative fair value method was used to reallocateIn 2018, there were no events or changes in circumstances identified that warranted interim goodwill for reporting units of which the composition had changed. No impairment indicators were identified as a result of the updated alignment and reallocation of goodwill.testing. In the fourth quarter of 2017,2018, quantitative testing was performed on eleventwo reporting units and a qualitative assessment was performed for the remaining reporting units.

For the quantitative testing, the fair values exceeded carrying values for both reporting units. Fair values exceeded carrying value in all scenarios where sensitivity analysis was performed, and the differences between fair value and carrying value of each reporting unit were determined to be reasonable. For the qualitative assessments, management considered the factors at both the Company level and the reporting unit level. Based on the qualitative assessment, management concluded it is not more likely than not that the fair value of the reporting unit is less than the carrying value of the reporting unit.

Table of quantitative testing in the fourth quarter of 2017, the Company determined the Coatings & Performance Monomers reporting unit was impaired. Throughout 2017, the Coatings & Performance Monomers reporting unit did not consistently meet expected financial performance targets, primarily due to increasing commoditization in coatings markets and competition, as well as customer consolidation in end markets which have reduced growth opportunities. As a result, the Coatings & Performance Monomers reporting unit lowered future revenue and profitability expectations. The fair value of the Coatings & Performance Monomers reporting unit was determined using a discounted cash flow methodology that reflected reductions in projected revenue growth rates, primarily driven by modified sales volume and pricing assumptions, as well as revised expectations for future growth rates. These discounted cash flows did not support the carrying value of the Coatings & Performance Monomers reporting unit. As a result, the Company recorded a goodwill impairment charge for the Coatings & Performance Monomers reporting unit of $1,491 million in the fourth quarter of 2017, included in “Restructuring, goodwill impairment and asset related charges - net” in the consolidated statements of income. At December 31, 2017, the Coatings & Performance Monomers reporting unit carried $1,071 million of goodwill.Contents

The fair values of the remaining reporting units exceeded their carrying values and no other goodwill impairments were identified as a result of the 2017 testing.

Pension and Other Postretirement Benefits
The amounts recognized in the consolidated financial statements related to pension and other postretirement benefits are determined from actuarial valuations. Inherent in these valuations are assumptions including expected return on plan assets, discount rates at which the liabilities could have been settled at December 31, 2017,2018, rate of increase in future compensation levels, mortality rates and health care cost trend rates. These assumptions are updated annually and are disclosed in Note 19 to the Consolidated Financial Statements. In accordance with U.S. GAAP, actual results that differ from the assumptions are accumulated and amortized over future periods and, therefore, affect expense recognized and obligations recorded in future periods. The U.S. pension plans represent 7071 percent of the Company’s pension plan assets and 7069 percent of the pension obligations.

On January 1, 2016, theThe Company adopteduses the spot rate approach to determine the discount rate utilized to measure the service cost and interest cost components of net periodic pension and other postretirement benefit costs for the U.S. and other selected countries. Under the spot rate approach, the Company calculates service costs and interest costs by applying individual spot rates

29



from the Willis Towers Watson RATE:Link yield curve (based on high-quality corporate bond yields) for each selected country to the separate expected cash flow components of service cost and interest cost; service cost and interest cost for all other plans (including all plans prior to adoption) are determined on the basis of the single equivalent discount rates derived in determining those plan obligations. The Company changed to this method to provide a more precise measure of interest and service costs for certain plans by improving the correlation between projected benefit cash flows and the discrete spot yield curves. The Company accounted for this change as a change in accounting estimate and it was applied prospectively starting in 2016.

The following information relates to the U.S. plans only; a similar approach is used for the Company’s non-U.S. plans.

The Company determines the expected long-term rate of return on assets by performing a detailed analysis of historical and expected returns based on the strategic asset allocation approved by the Company's Investment Committee and the underlying return fundamentals of each asset class. The Company’s historical experience with the pension fund asset performance is also considered. The expected return of each asset class is derived from a forecasted future return confirmed by historical experience. The expected long-term rate of return is an assumption and not what is expected to be earned in any one particular year. The weighted-average long-term rate of return assumption used for determining net periodic pension expense for 20172018 was 7.917.92 percent. The weighted-average assumption to be used for determining 20182019 net periodic pension expense is 7.927.94 percent. Future actual pension expense will depend on future investment performance, changes in future discount rates and various other factors related to the population of participants in the Company’s pension plans.

The discount rates utilized to measure the pension and other postretirement obligations of the U.S. qualified plans are based on the yield on high-quality corporate fixed income investments at the measurement date. Future expected actuarially determined cash flows for Dow’s U.S. plans are individually discounted at the spot rates under the Willis Towers Watson U.S. RATE:Link 60-90 corporate yield curve (based on 60th to 90th percentile high-quality corporate bond yields) to arrive at the plan’s obligations as of the measurement date. The weighted average discount rate utilized to measure pension obligations decreasedincreased to 4.39 percent at December 31, 2018, from 3.66 percent at December 31, 2017, from 4.11 percent at December 31, 2016.2017.

At December 31, 2017,2018, the U.S. qualified plans were underfunded on a projected benefit obligation basis by approximately $5.4 billion.$4,066 million. The underfunded amount increased approximately $240decreased $1,297 million compared with December 31, 2016.2017. The increasedecrease in the underfunded amount in 20172018 was primarily due to the changeimpact of higher discount rates and discretionary plan contributions made in the discount rate.2018. The Company contributed $200$1,285 million to the U.S. qualified plans in 2017.2018.

The assumption for the long-term rate of increase in compensation levels for the U.S. qualified plans was 4.25 percent. The Company uses a generational mortality table to determine the duration of its pension and other postretirement obligations.

The following discussion relates to the Company’s significant pension plans.

The Company bases the determination of pension expense on a market-related valuation of plan assets that reduces year-to-year volatility. This market-related valuation recognizes investment gains or losses over a five-year period from the year in which they occur. Investment gains or losses for this purpose represent the difference between the expected return calculated using the market-related value of plan assets and the actual return based on the market value of plan assets. Since the market-related value of plan assets recognizes gains or losses over a five-year period, the future value of plan assets will be impacted when previously deferred gains or losses are recorded. Over the life of the plans, both gains and losses have been recognized and amortized. At December 31, 2017,2018, net gainslosses of $293$1,505 million remain to be recognized in the calculation of the market-related value of plan assets. These net gainslosses will result in decreasesincreases in future pension expense as they are recognized in the market-related value of assets.

The net increasedecrease in the market-related value of assets due to the recognition of prior gains (losses)losses is presented in the following table:

The Company expects pension expense to decrease in 20182019 by approximately $700$130 million. Excluding a settlement charge resulting from the changeThe decrease in control of the Company which occurred at the time of the Merger, pension expense is expectedprimarily due to decrease approximately $15 million in 2018.the impact of higher discount rates and the full year impact of the significant 2018 contributions to the Company's U.S. pension plans.

A 25 basis point increase or decrease in the long-term return on assets assumption would change the Company’s total pension expense for 20182019 by $57$58 million. A 25 basis point increase in the discount rate assumption would lower the Company's total pension expense for 20182019 by $64$52 million. A 25 basis point decrease in the discount rate assumption would increase the Company's total pension expense for 20182019 by $66$62 million. A 25 basis point change in the long-term return and discount rate assumptions would have an immaterial impact on the other postretirement benefit expense for 2018.2019.

Income Taxes
Deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and tax bases of assets and liabilities, applying enacted tax rates expected to be in effect for the year in which the differences are expected to reverse. Based on the evaluation of available evidence, both positive and negative, the Company recognizes future tax benefits, such as net operating loss carryforwards and tax credit carryforwards, to the extent that realizing these benefits is considered to be more likely than not.

At December 31, 2017,2018, the Company had a net deferred tax asset balance of $958$1,367 million, after valuation allowances of $1,371$1,320 million.

In evaluating the ability to realize the deferred tax assets, the Company relies on, in order of increasing subjectivity, taxable income in prior carryback years, the future reversals of existing taxable temporary differences, tax planning strategies and forecasted taxable income using historical and projected future operating results.

At December 31, 2017,2018, the Company had deferred tax assets for tax loss and tax credit carryforwards of $1,734$2,244 million, $285$300 million of which is subject to expiration in the years 20182019 through 2022.2023. In order to realize these deferred tax assets for tax loss and tax credit carryforwards, the Company needs taxable income of approximately $24,457$28,758 million across multiple jurisdictions. The taxable income needed to realize the deferred tax assets for tax loss and tax credit carryforwards that are subject to expiration between 20182019 through 20222023 is approximately $4,852$4,458 million.

The Company recognizes the financial statement effects of an uncertain income tax position when it is more likely than not, based on technical merits, that the position will be sustained upon examination. At December 31, 2017,2018, the Company had uncertain tax positions for both domestic and foreign issues of $253$313 million.

The Company accrues for non-income 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. At December 31, 2017,2018, the Company had a non-income tax contingency reserve for both domestic and foreign issues of $110$91 million.

On December 22, 2017, the Tax Cuts and JobsThe Act (“The Act”) was enacted, making significant changes to the U.S. tax law (see Note 9 to the Consolidated Financial Statements for additional information). The SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance onAt December 31, 2017, the Company had not completed its accounting for the tax effects of The Act for whichAct; however, the accounting under ASC 740, "Income Taxes" (“ASC 740”) is incomplete.

Environmental Matters
Environmental Policies
Dow is committed to world-class environmental, health and safety (“EH&S”) performance, as demonstrated by industry-leading performance, a long-standing commitment to RESPONSIBLE CARE®, and a strong commitment to achieve the Company’s 2025 Sustainability Goals – goals that set the standard for sustainability in the chemical industry by focusing on improvements in Dow’s local corporate citizenship and product stewardship, and by actively pursuing methods to reduce the Company’s environmental impact.

To meet the Company’s public commitments, as well as the stringent laws and government regulations related to environmental protection and remediation to which its global operations are subject, Dow has well-defined policies, requirements and management systems. Dow’s EH&S Management System (“EMS”) defines the “who, what, when and how” needed for the businesses to achieve the Company’s policies, requirements, performance objectives, leadership expectations and public commitments. To ensure effective utilization, the EMS is integrated into a company-wide management system for EH&S, Operations, Quality and Human Resources.

It is Dow’s policy to adhere to a waste management hierarchy that minimizes the impact of wastes and emissions on the environment. First, Dow works to eliminate or minimize the generation of waste and emissions at the source through research, process design, plant operations and maintenance. Second, Dow finds ways to reuse and recycle materials. Finally, unusable or non-recyclable hazardous waste is treated before disposal to eliminate or reduce the hazardous nature and volume of the waste. Treatment may include destruction by chemical, physical, biological or thermal means. Disposal of waste materials in landfills is considered only after all other options have been thoroughly evaluated. Dow has specific requirements for waste that is transferred to non-Dow facilities, including the periodic auditing of these facilities.

Dow believes third-party verification and transparent public reporting are cornerstones of world-class EH&S performance and building public trust. Numerous Dow sites in Europe, Latin America, Asia Pacific and U.S. & Canada have received third-party verification of Dow’s compliance with RESPONSIBLE CARE® and with outside specifications such as ISO-14001. Dow continues to be a global champion of RESPONSIBLE CARE® and has worked to broaden the application and impact of RESPONSIBLE CARE® around the world through engagement with suppliers, customers and joint venture partners.

Dow’s EH&S policies helped the Company achieve improvements in many aspects of EH&S performance in 2017.2018. Dow’s process safety performance was excellent in 20172018 and improvements were made in injury/illness rates. Safety remains a priority for the entire Company. Further improvement in these areas, as well as environmental compliance, remains a top management priority, with initiatives underway to further improve performance and compliance in 20182019 as Dow continues to implement the Company's 2025 Sustainability Goals.

Detailed information on Dow’s performance regarding environmental matters and goals can be found online on Dow’s Science & Sustainability webpage at www.dow.com. The Company's website and its content are not deemed incorporated by reference into this report.

Chemical Security
Public and political attention continues to be placed on the protection of critical infrastructure, including the chemical industry, from security threats. Terrorist attacks, natural disasters and cyber incidents have increased concern about the security and safety of chemical production and distribution. Many, including Dow and the American Chemistry Council, have called for uniform risk-based and performance-based national standards for securing the U.S. chemical industry. The Maritime Transportation Security Act of 2002 and its regulations further set forth risk-based and performance-based standards that must be met at U.S. Coast Guard-regulated facilities. U.S. Chemical Plant Security legislation was passed in 2006 and the Department of Homeland Security is now implementing the regulations known as the Chemical Facility Anti-Terrorism Standards. The Company is complying with the requirements of the Rail Transportation Security Rule issued by the U.S. Transportation Security Administration. Dow continues to support uniform risk-based national standards for securing the chemical industry.

The focus on security, emergency planning, preparedness and response is not new to Dow. A comprehensive, multi-level security plan for the Company has been maintained since 1988. This plan, which has been activated in response to significant world and national events since then, is reviewed on an annual basis. Dow continues to improve its security plans, placing emphasis on the safety of Dow communities and people by being prepared to meet risks at any level and to address both internal and external identifiable risks. The security plan includes regular vulnerability assessments, security audits, mitigation efforts and physical security upgrades designed to reduce vulnerability. Dow’s security plans also are developed to avert interruptions of normal business operations that could materially and adversely affect the Company’s results of operations, liquidity and financial condition.

Dow played a key role in the development and implementation of the American Chemistry Council’s RESPONSIBLE CARE® Security Code ("Security Code"), which requires that all aspects of security – including facility, transportation and cyberspace – be assessed and gaps addressed. Through the Company’s global implementation of the Security Code, Dow has permanently heightened the level of security – not just in the United States, but worldwide. Dow employs several hundred employees and contractors in its Emergency Services and Security department worldwide.

Through the implementation of the Security Code, including voluntary security enhancements and upgrades made since 2002, Dow is well-positioned to comply with U.S. chemical facility regulations and other regulatory security frameworks. Dow is currently participating with the American Chemistry Council to review and update the Security Code.

Dow continues to work collaboratively across the supply chain on RESPONSIBLE CARE®, Supply Chain Design, Emergency Preparedness, Shipment Visibility and transportation of hazardous materials. Dow is cooperating with public and private entities to lead the implementation of advanced tank car design, and track and trace technologies. Further, Dow’s Distribution Risk Review process that has been in place for decades was expanded to address potential threats in all modes of transportation across the Company’s supply chain. To reduce vulnerabilities, Dow maintains security measures that meet or exceed regulatory and industry security standards in all areas in which the Company operates.

Dow's initiatives relative to chemical security, emergency preparedness and response, Community Awareness and Emergency Responses and crisis management are implemented consistently at all Dow sites on a global basis. Dow participates with chemical associations globally and participates as an active member of the U.S. delegation to the G7 Global Partnership Sub-Working Group on Chemical Security.

Climate Change
Climate change matters for Dow are likely to be driven by changes in regulations, public policy and physical climate parameters.

Regulatory Matters
Regulatory matters include cap and trade schemes; increased greenhouse gas (“GHG”) limits; and taxes on GHG emissions, fuel and energy. The potential implications of each of these matters are all very similar, including increased cost of purchased energy, additional capital costs for installation or modification of GHG emitting equipment, and additional costs associated directly with GHG emissions (such as cap and trade systems or carbon taxes), which are primarily related to energy use. It is difficult to estimate the potential impact of these regulatory matters on energy prices.

Reducing Dow's overall energy usage and GHG emissions through new and unfolding projects will decrease the potential impact of these regulatory matters. Dow also has a dedicated commercial group to handle energy contracts and purchases, including managing emissions trading. The Company has not experienced any material impact related to regulated GHG emissions. The Company continues to evaluate and monitor this area for future developments.

Physical Climate Parameters
Many scientific academies throughout the world have concluded that it is very likely that human activities are contributing to global warming. At this point, it is difficult to predict and assess the probability and opportunity of a global warming trend on Dow specifically. Preparedness plans are developed that detail actions needed in the event of severe weather. These measures have historically been in place and these activities and associated costs are driven by normal operational preparedness. Dow continues to study the long-term implications of changing climate parameters on water availability, plant siting issues, and impacts and opportunities for products.

Dow’s Energy business and Public Affairs and Sustainability functions are tasked with developing and implementing a comprehensive strategy that addresses the potential challenges of energy security and GHG emissions on the Company. The Company continues to elevate its internal focus and external positions - to focus on the root causes of GHG emissions - including the unsustainable use of energy. Dow's energy plan provides the roadmap:

Conserve - aggressively pursue energy efficiency and conservation
Optimize - increase and diversify energy resources
Accelerate - develop cost-effective, clean, renewable and alternative energy sources
Transition - to a sustainable energy future

Through corporate energy efficiency programs and focused GHG management efforts, the Company has and is continuing to reduce its GHG emissions footprint. The Company’s manufacturing intensity, measured in Btu per pound of product, has improved by more than 40 percent since 1990. As part of the Company's 2025 Sustainability Goals, Dow will maintain GHG emissions below 2006 levels on an absolute basis for all GHGs.

Dow intends to implement the recommendations of the Financial Stability Board Task Force on Climate-Related Disclosures ("Task Force") over the next threetwo to fivefour years, which is aligned with the recommendations of the Task Force.

Environmental Remediation
Dow accrues the costs of remediation of its facilities and formerly owned facilities based on current law and regulatory requirements. The nature of such remediation can include management of soil and groundwater contamination. The accounting policies adopted to properly reflect the monetary impacts of environmental matters are discussed in Note 1 to the Consolidated Financial Statements. To assess the impact on the financial statements, environmental experts review currently available facts to evaluate the probability and scope of potential liabilities. Inherent uncertainties exist in such evaluations primarily due to unknown environmental conditions, changing governmental regulations and legal standards regarding liability, and the ability to apply remediation technologies. These liabilities are adjusted periodically as remediation efforts progress or as additional technical or legal information becomes available. Dow had an accrued liability of $726$664 million at December 31, 2017,2018, related to the remediation of current or former Dow-owned sites. At December 31, 2016,2017, the liability related to remediation was $758$726 million.

In addition to current and former Dow-owned sites, under the federal Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA") and equivalent state laws (hereafter referred to collectively as "Superfund Law"), Dow is liable for remediation of other hazardous waste sites where Dow allegedly disposed of, or arranged for the treatment or disposal of, hazardous substances. Because Superfund Law imposes joint and several liability upon each party at a site, Dow has evaluated its potential liability in light of the number of other companies that also have been named potentially responsible parties (“PRPs”) at each site, the estimated apportionment of costs among all PRPs, and the financial ability and commitment of each to pay its expected share. The Company’s remaining liability for the remediation of Superfund sites was $152$156 million at December 31, 20172018 ($151152 million at December 31, 2016)2017). The Company has not recorded any third-party recovery related to these sites as a receivable.

1.Dow-owned sites are sites currently or formerly owned by Dow. In the United States, remediation obligations are imposed by the Resource Conservation and Recovery Act or analogous state law. At December 31, 2017, 352018, 32 of these sites (38(35 sites at December 31, 2016)2017) were formerly owned by Dowell Schlumberger, Inc., a group of companies in which the Company previously owned a 50 percent interest. Dow sold its interest in Dowell Schlumberger in 1992.
2.Superfund sites are sites, including sites not owned by Dow, where remediation obligations are imposed by Superfund Law.

Additional information is provided below for the Company’s Midland, Michigan, manufacturing site and Midland off-site locations (collectively, the "Midland sites"), as well as a Superfund site in Wood-Ridge, New Jersey, the locations for which the Company has the largest potential environmental liabilities.

In the early days of operations at the Midland manufacturing site, wastes were usually disposed of on-site, resulting in soil and groundwater contamination, which has been contained and managed on-site under a series of Resource Conservation and Recovery Act permits and regulatory agreements. The Hazardous Waste Operating License for the Midland manufacturing site, issued in 2003, and renewed and replaced in September 2015, also included provisions for the Company to conduct an investigation to

34

Table of Contents


determine the nature and extent of off-site contamination from historic Midland manufacturing site operations. In January 2010, the Company, the U.S. Environmental Protection Agency ("EPA") and the State of Michigan ("State") entered into an Administrative Order on Consent that requires the Company to conduct a remedial investigation, a feasibility study and a remedial design for the Tittabawassee River, the Saginaw River and the Saginaw Bay, and pay the oversight costs of the EPA and the State under the authority of CERCLA. See Note 16 to the Consolidated Financial Statements for additional information. At December 31, 2017,2018, the Company had an accrual of $131$134 million ($137131 million at December 31, 2016)2017) for environmental remediation and investigation associated with the Midland sites. In 2017,2018, the Company spent $24$26 million ($3624 million in 2016)2017) for environmental remediation at the Midland sites.

Rohm and Haas, a wholly owned subsidiary of Dow, is a PRP at the Wood-Ridge, New Jersey Ventron/Velsicol Superfund Site, and the adjacent Berry’s Creek Study Area ("BCSA") (collectively, the "Wood-Ridge sites"). Rohm and Haas is a successor in interest to a company that owned and operated a mercury processing facility, where wastewater and waste handling resulted in contamination of soils and adjacent creek sediments. The Berry’s Creek Study Area PRP group completed a multi-stage Remedial Investigation ("RI") pursuant to an Administrative Order on Consent with U.S. EPA Region 2 to identify contamination in surface water, sediment and biota related to numerous contaminated sites in the Berry's Creek watershed, and submitted the report to the

35

Table of Contents


EPA in June 2016. That same month, the EPA concluded that an "iterative or adaptive approach" was appropriate for cleaning up the BCSA. Thus, each phase of remediation will be followed by a period of monitoring to assess its effectiveness and determine if there is a need for more work. The Feasibility Study ("FS") for the first phase of work will bewas submitted in the second halfthird quarter of 2018. The EPA will then reviewselected the remedial options presented in the FS, select theinterim remedy and issueissued an interim Record of Decision ("ROD"). The PRP group will then attempt to negotiateis negotiating agreements among the PRP's to fund design of the selected remedy and with the EPA to performdesign the remediation.selected remedy. Although there is currently much uncertainty as to what will ultimately be required to remediate the BCSA and Rohm and Haas's share of these costs has yet to be determined, the range of activities that will beare required in the interim ROD is known in general terms. Based on the first phase of the RI and agreement withinterim remedy selected by the EPA, the overall remediation accrual for the Wood-Ridge sites was increased by $80$21 million in the fourth quarter of 2016.2018. At December 31, 2017,2018, the Company had an accrual of $88$106 million ($9188 million at December 31, 2016)2017) for environmental remediation at the Wood-Ridge sites. In 2017,2018, the Company spent $7$6 million ($67 million in 2016)2017) on environmental remediation at the Wood-Ridge sites.

In the fourth quarter of 2016, the Company recorded a pretax charge of $295 million for environmental remediation at a number of historical locations, including the Midland manufacturing site/off-site matters and the Wood-Ridge sites, primarily resulting from the culmination of negotiations with regulators and/or final agency approval. This charge was included in "Cost of sales" in the consolidated statements of income. In total, the Company’s accrued liability for probable environmental remediation and restoration costs was $820 million at December 31, 2018, compared with $878 million at December 31, 2017, compared with $909 million at December 31, 2016.2017. 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 approximately two times that amount. 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. It is the opinion of the Company’s management, however, that the possibility is remote that costs in excess of the range disclosed will have a material impact on the Company’s results of operations, financial condition and cash flows.

The amounts charged to income on a pretax basis related to environmental remediation totaled $174 million in 2018, $171 million in 2017 and $504 million in 2016 and $218 million in 2015.2016. The amounts charged to income on a pretax basis related to operating the Company’s current pollution abatement facilities, excluding internal recharges, totaled $772 million in 2018, $640 million in 2017 and $623 million in 2016 and $613 million in 2015.2016. Capital expenditures for environmental protection were $76 million in 2018, $79 million in 2017 and $66 million in 2016 and $49 million in 2015.2016.

Asbestos-Related Matters of Union Carbide Corporation
Union Carbide is and has been involved in a large number of asbestos-related suits filed primarily in state courts during the past four decades. These suits principally allege personal injury resulting from exposure to asbestos-containing products and frequently seek both actual and punitive damages. The alleged claims primarily relate to products that Union Carbide sold in the past, alleged exposure to asbestos-containing products located on Union Carbide’s premises, and Union Carbide’s responsibility for asbestos suits filed against a former Union Carbide subsidiary, Amchem. In many cases, plaintiffs are unable to demonstrate that they have suffered any compensable loss as a result of such exposure, or that injuries incurred in fact resulted from exposure to Union Carbide’s products.

The table below provides information regarding asbestos-related claims pending against Union Carbide and Amchem based on criteria developed by Union Carbide and its external consultants. Union Carbide had a significant increase in the number of claims settled, dismissed or otherwise resolved in 2015 resulting from a detailed review of the status of individual claims and an update to criteria used to classify claims.

Plaintiffs’ lawyers often sue numerous defendants in individual lawsuits or on behalf of numerous claimants. As a result, the damages alleged are not expressly identified as to Union Carbide, Amchem or any other particular defendant, even when specific damages are alleged with respect to a specific disease or injury. In fact, there are no asbestos personal injury cases in which only Union Carbide and/or Amchem are the sole named defendants. For these reasons and based upon Union Carbide’s litigation and settlement experience, Union Carbide does not consider the damages alleged against Union Carbide and Amchem to be a meaningful factor in its determination of any potential asbestos-related liability.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Dow’s business operations give rise to market risk exposure due to changes in foreign exchange rates, interest rates, commodity prices and other market factors such as equity prices. To manage such risks effectively, the Company enters into hedging transactions, pursuant to established guidelines and policies that enable it to mitigate the adverse effects of financial market risk. Derivatives used for this purpose are designated as hedges per the accounting guidance related to derivatives and hedging activities, where appropriate. A secondary objective is to add value by creating additional non-specific exposure within established limits and policies; derivatives used for this purpose are not designated as hedges. The potential impact of creating such additional exposures is not material to the Company’s results.
  
The global nature of Dow’s business requires active participation in the foreign exchange markets. As a result of investments, production facilities and other operations on a global basis, theThe Company has assets, liabilities and cash flows in currencies other than the U.S. dollar. The primary objective of the Company’s foreign exchangecurrency risk management is to optimize the U.S. dollar value of net assets and cash flows, keeping the adverse impact of currency movements to a minimum.flows. To achieve this objective, the Company hedges on a net exposure basis using foreign currency forward contracts, over-the-counter option contracts, cross-currency swaps and nonderivative instruments in foreign currencies. Exposures primarily relate to assets, liabilities and bonds denominated in foreign currencies, as well as economic exposure, which is derived from the risk that currency fluctuations could affect the dollar value of future cash flows related to operating activities. The largest exposures are denominated in European currencies, the Japanese yen and the Chinese yuan, although exposures also exist in other currencies of Asia Pacific, Canada, Latin America, Middle East, Africa and India.

The main objective of interest rate risk management is to reduce the total funding cost to the Company and to alter the interest rate exposure to the desired risk profile. Dow usesTo achieve this objective, the Company hedges using interest rate swaps, “swaptions,” and exchange-traded instruments to accomplish this objective.instruments. The Company’s primary exposure is to the U.S. dollar yield curve.

Dow has a portfolio of equity securities derived primarily from the investment activities of its insurance subsidiaries. This exposure is managed in a manner consistent with the Company’s market risk policies and procedures.

Inherent in Dow’s business is exposure to price changes for several commodities. Some exposures can be hedged effectively through liquid tradable financial instruments. Natural gas and crude oil, along with feedstocks for ethylene and propylene production, constitute the main commodity exposures. Over-the-counter and exchange traded instruments are used to hedge these risks, when feasible.

Dow uses value-at-risk (“VAR”), stress testing and scenario analysis for risk measurement and control purposes. VAR estimates the maximum potential loss in fair market values, given a certain move in prices over a certain period of time, using specified confidence levels. The VAR methodology used by the Company is a variance/covariance model. This model uses a 97.5 percent confidence level and includes at least one year of historical data. The 20172018 and 20162017 year-end and average daily VAR for the aggregate of all positions are shown below. These amounts are immaterial relative to the total equity of the Company.

NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Principles of Consolidation and Basis of Presentation
The accompanying consolidated financial statements of The Dow Chemical Company and its subsidiaries (“Dow” or the “Company”) were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the assets, liabilities, revenues and expenses of all majority-owned subsidiaries over which the Company exercises control and, when applicable, entities for which the Company has a controlling financial interest or is the primary beneficiary. Intercompany transactions and balances are eliminated in consolidation. Investments in nonconsolidated affiliates (20-50 percent owned companies or less than 20 percent owned companies over which significant influence is exercised) are accounted for using the equity method.

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, Dow and E. I. du Pont de Nemours and Company ("DuPont") each merged with subsidiaries of DowDuPont Inc. ("DowDuPont") and, as a result, Dow and DuPont became subsidiaries of DowDuPont (the "Merger"). In accordance with the accounting guidance for earnings per share, the presentation of earnings per share is not required in financial statements of wholly owned subsidiaries. See Note 3 for additional information on the Merger.

44

Table of Contents


Beginning September 1, 2017, transactions between DowDuPont, Dow and DuPont and their affiliates are reflected in these consolidated financial statements and will be disclosed as related party transactions, when material. Transactions between Dow and DuPont primarily consist of the sale and procurement of certain feedstocks, energy and raw materials that are consumed in each company's manufacturing process. Transactions with DuPont during the period from September 1, 2017 through December 31, 2017, were not material to the consolidated financial statements. See Note 24 for additional information.

Effective with the Merger, Dow’s business activities are components of its parent company’s business operations. Dow’s business activities, including the assessment of performance and allocation of resources, are reviewed and managed by DowDuPont. Information used by the chief operating decision maker of Dow relates to the Company in its entirety. Accordingly, there are no separate reportable business segments for the Company under Accounting Standards Codification ("ASC") Topic 280 “Segment Reporting” and the Company’s business results are reported in this Form 10-K as a single operating segment.

Except as otherwise indicated by the context, the term "Union Carbide" means Union Carbide Corporation, a wholly owned subsidiary of Dow, and "Dow Silicones" means Dow Silicones Corporation (formerly known as Dow Corning Corporation, which changed its name effective as of February 1, 2018), a wholly owned subsidiary of Dow.

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.

Significant Accounting Policies
Asbestos-Related Matters
Accruals for asbestos-related matters, including defense and processing costs, are recorded based on an analysis of claim and resolution activity, defense spending, and pending and future claims. These accruals are assessed at each balance sheet date to determine if the asbestos-related liability remains appropriate. Accruals for asbestos-related matters are included in the consolidated balance sheets in “Accrued and other current liabilities” and “Asbestos-related liabilities - noncurrent.” This accounting policy was added in the fourth quarter of 2016. See Note 16 for additional information.

Legal Costs
The Company expenses legal costs as incurred, with the exception of defense and processing costs associated with asbestos-related matters.

Foreign Currency Translation
The local currency has been primarily used as the functional currency throughout the world. Translation gains and losses of those operations that use local currency as the functional currency are included in the consolidated balance sheets in "Accumulated other comprehensive loss" ("AOCL"). For certain subsidiaries, the U.S. dollar is used as the functional currency. This occurs when the subsidiary operates in an economic environment where the products produced and sold are tied to U.S. dollar-denominated markets, or when the foreign subsidiary operates in a hyper-inflationary environment. Where the U.S. dollar is used as the functional currency, foreign currency translation gains and losses are reflected in income.

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. 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 in “Accounts and notes receivable - Other.”

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.

Cash and Cash Equivalents
Cash and cash equivalents include time deposits and investments with maturities of three months or less at the time of purchase.

Table of Contents


Financial Instruments
The Company calculates the fair value of financial instruments using quoted market prices when available. When quoted market prices are not available for financial instruments, the Company uses standard pricing models with market-based inputs that take into account the present value of estimated future cash flows.

The Company utilizes derivatives to manage exposures to foreign currency exchange rates, commodity prices and interest rate risk. The fair values of all derivatives are recognized as assets or liabilities at the balance sheet date. Changes in the fair values of these instruments are reported in income or AOCL, depending on the use of the derivative and whether the Company has elected hedge accounting treatment.

Gains and losses on derivatives that are designated and qualify as cash flow hedging instruments are recorded in AOCL to the extent the hedges are effective, until the underlying transactions are recognized in income. To the extent effective, gainsGains and losses on derivative and non-derivative instruments used as hedges of the Company’s net investment in foreign operations are recorded in AOCL as part of the cumulative translation adjustment. ThePrior to the adoption of Accounting Standards Update ("ASU") 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities" in 2018, the ineffective portions of cash flow hedges, and hedges of net investment in foreign operations, if any, arewere recognized in income immediately. See Note 2 for additional information.

Gains and losses on derivatives designated and qualifying as fair value hedging instruments, as well as the offsetting losses and gains on the hedged items, are reported in income in the same accounting period. Derivatives not designated as hedging instruments are marked-to-market at the end of each accounting period with the results included in income.

Inventories
Inventories are stated at the lower of cost or net realizable value. The method of determining cost for each subsidiary varies among last-in, first-out (“LIFO”); first-in, first-out (“FIFO”); and average cost, and is used consistently from year to year. At December 31, 2017,2018, approximately 24 percent, 6770 percent and 96 percent of the Company's inventories were accounted for under the LIFO, FIFO and average cost methods, respectively. At December 31, 2016,2017, approximately 2824 percent, 6267 percent and 109 percent of the Company's inventories were accounted for under the LIFO, FIFO and average cost methods, respectively.

The Company routinely exchanges and swaps raw materials and finished goods with other companies to reduce delivery time, freight and other transportation costs. These transactions are treated as non-monetary exchanges and are valued at cost.

Property
Land, buildings and equipment, including property under capital lease agreements, are carried at cost less accumulated depreciation. Depreciation is based on the estimated service lives of depreciable assets and is calculated using the straight-line method, unless the asset was capitalized before 1997 when the declining balance method was used. Fully depreciated assets are retained in property and accumulated depreciation accounts until they are removed from service. In the case of disposals, assets and related accumulated depreciation are removed from the accounts, and the net amounts, less proceeds from disposal, are included in income.

Impairment and Disposal of Long-Lived Assets
The Company evaluates long-lived assets and certain identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When undiscounted future cash flows are not expected to be sufficient to recover an asset’s carrying amount, the asset is written down to its fair value based on bids received from third parties or a discounted cash flow analysis based on market participant assumptions.

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, and depreciation is recognized over the remaining useful life of the assets.

Goodwill and Other Intangible Assets
The Company records goodwill when the purchase price of a business combination exceeds the estimated fair value of net identified tangible and intangible assets acquired. Goodwill is tested for impairment at the reporting unit level annually in 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 may first assess qualitative factors. If an initial qualitative assessment identifies that it is more likely than not that the fair value of a reporting unit is less than its carrying value, additional quantitative testing is performed. The Company may also elect to skip the qualitative testing and proceed directly to the quantitative testing. If the quantitative testing indicates that goodwill is impaired, an impairment charge is recognized based on the difference between the reporting unit's carrying value and its fair value. The Company primarily utilizes a discounted cash flow methodology to calculate the fair value of its reporting units.

Table of Contents


Finite-lived intangible assets such as purchased customer lists, developed technology, patents, trademarks and software, are amortized over their estimated useful lives, generally on a straight-line basis for periods ranging primarily from three3 to twenty20 years. Indefinite-lived intangible assets are reviewed for impairment or obsolescence annually, or more frequently when events or changes in circumstances indicate that the carrying amount of an intangible asset may not be recoverable. If impaired, intangible assets are written down to fair value based on discounted cash flows.

Asset Retirement Obligations
The Company records asset retirement obligations as incurred and reasonably estimable, including obligations for which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the Company. The fair values of obligations are recorded as liabilities on a discounted basis and are accreted over time for the change in present value. Costs associated with the liabilities are capitalized and amortized over the estimated remaining useful life of the asset, generally for periods of 10 years or less.

Investments
Investments in debt and marketable equity securities, (including warrants), primarily held by the Company’s insurance operations, are classified as trading, available-for-sale or held-to-maturity. Investments classified as trading are reported at fair value with unrealized gains and losses related to mark-to-market adjustments included in income. Those classified as available-for-sale are reported at fair value with unrealized gains and losses recorded in AOCL. Those classified as held-to-maturity are recorded at amortized cost. The cost of investments sold is determined by FIFO or specific identification.

Investments in equity securities, primarily held by the Company’s insurance operations, with a readily determinable fair value are reported at fair value with unrealized gains and losses related to mark-to-market adjustments included in income. Equity securities without a readily determinable fair value are accounted for at cost, adjusted for impairments and observable price changes in orderly transactions.

The Company routinely reviews available-for-sale and held-to-maturity securitiesits investments for other-than-temporary declines in fair value below the cost basis. When events or changes in circumstances indicate the carrying value of an asset may not be recoverable, the security is written down to fair value, establishing a new cost basis.

Revenue
Sales are recognized whenEffective with the revenue is realized or realizable,January 1, 2018 adoption of ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)," and the earnings process is complete. Approximately 98 percentassociated ASUs (collectively, "Topic 606"), the Company recognizes revenue when its customer obtains control of promised goods or services in an amount that reflects the Company’s salesconsideration which the Company expects to receive in 2017 related to salesexchange for those goods or services. To determine revenue recognition for the arrangements that the Company determines are within the scope of product (99 percentTopic 606, the Company performs the following five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in 2016 and 99 percent in 2015). The remaining 2 percent in 2017 primarily relatedthe contract, (3) determine the transaction price, (4) allocate the transaction price to the Company’s insurance operations and licensing of patents and technology (1 percent in 2016 and 1 percent in 2015). Revenue for product sales is recognized as risk and title to the product transfer to the customer, which usually occurs at the time shipment is made. As such, title to the product passes when the product is delivered to the freight carrier. The Company’s standard terms of delivery are included in its contracts of sale, order confirmation documents and invoices. Freight costs and any directly related costs of transporting finished product to customers are recorded as “Cost of sales”performance obligations in the consolidated statements of income.contract and (5) recognize revenue when (or as) the entity satisfies a performance obligation. See Note 4 for additional information.

Revenue related to the Company's insurance operations includes third-party insurance premiums, which are earned over the terms of the related insurance policies and reinsurance contracts.

In periods prior to the adoption of Topic 606, the Company's accounting policy was to recognize revenue when it was realized or realizable, and the earnings process was complete. Revenue for product sales was recognized as risk and title to the product transferred to the customer, which usually occurred at the time shipment was made. As such, title to the product passed when the product was delivered to the freight carrier. The Company’s standard terms of delivery were included in its contracts of sale, order confirmation documents and invoices. Revenue related to the initial licensing of patentspatent and technology iswas recognized when earned; revenue related to running royalties iswas recognized according to licensee production levels.

Severance Costs
The Company routinely reviews its operations around the world in an effort to ensure competitiveness across its businesses and geographic regions. When the reviews result in a workforce reduction related to the shutdown of facilities or other optimization activities, severance benefits are provided to employees primarily under Dow’s ongoing benefit arrangements. These severance costs are accrued once 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.

Integration and Separation Costs
The Company classifies expenses related to the Merger and the ownership restructure of Dow Corning Corporation ("Dow Corning")Silicones as "Integration and separation costs" in the consolidated statements of income. Merger-related costs include: costs incurred to prepare for and close the Merger, post-Merger integration expenses and costs incurred to prepare for the separation of the agriculture business, specialty productsmaterials science business and materials sciencespecialty products business. The Dow Corning related-costs include:Silicones-related costs include costs incurred to prepare for and close the ownership restructure, as well as integration expenses. These costs primarily consist of financial advisor, information technology, legal, accounting, consulting and other professional advisory fees associated with preparation and execution of these activities. This accounting policy was added in the third quarter of 2017 as a result of the Merger.

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 uses the portfolio approach for releasing income tax effects from AOCL.

Effective with the Merger, the Company and DuPont are subsidiaries of DowDuPont. The Company is included in DowDuPont's consolidated tax groups and related income tax returns within certain jurisdictions.

47

Table of Contents


The Company will continue to record a separate tax liability for its share of the taxable income and tax attributes and obligations on DowDuPont’s consolidated income tax returns following a formula consistent with the economic sharing of tax attributes and obligations. Dow and DuPont compute the amount due to DowDuPont for their share of taxable income and tax attributes and obligations on DowDuPont’s consolidated tax return. The amounts reported as income tax payable or receivable represent the Company’s payment obligation (or refundable amount) to DowDuPont based on a theoretical tax liability calculated based on the methodologies agreed, elected or required in each combined or consolidated filing jurisdiction.

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.

Provision is made for taxes on undistributed earnings of foreign subsidiaries and related companies to the extent that such earnings are not deemed to be permanently invested.

Adoption of Accounting Standards Update ("ASU") 2016-09, "Compensation - Stock Compensation (Topic 718): ImprovementsChanges to Employee Share-Based Payment Accounting"Prior Period Consolidated Financial Statements
In the first quarter of 2017,2018, the Company adopted new accounting standards that required retrospective application. The Company updated the consolidated statements of income as a result of adopting ASU 2016-092017-07, "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and electedNet Periodic Postretirement Benefit Cost." The consolidated statements of cash flows were updated as a result of adopting ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments" and ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash." See Note 2 for additional information on the ASUs. In the third quarter of 2018, the U.S. Securities and Exchange Commission's ("SEC") Office of the Chief Accountant provided additional guidance related to apply changes on aASU 2016-15 that indicated an entity must evaluate daily transaction activity to calculate the value of cash received from beneficial interests in conduits, resulting in additional retrospective basisupdates to the consolidated statements of cash flows related to the classification of excess tax benefits and employee taxes paid for share-based payment arrangements. See Note 2 for additional information. The following table summarizes the changes made to the consolidated statements of cash flows for the years ended December 31, 2016 and 2015:

The most significant changes as a result of adopting Topic 606 relate to the Company's contract liabilities which include payments received in advance of performance. Contract liabilities, which are included in "Accrued and other current liabilities" and "Other noncurrent obligations" in the consolidated balance sheets, increased as certain performance obligations, which were previously recognized over time and related to the licensing of certain rights to patents and technology, as well as other performance obligations, are now recognized at a point in time as none of the three criteria for 'over time' recognition under Topic 606 are met.

In the second quarter of 2018, the Company early adopted ASU 2018-02. This standard was adopted on April 1, 2018, and resulted in a $1,057 million increase to retained earnings due to the reclassification from accumulated other comprehensive loss. The reclassification was primarily related to the change in the federal corporate tax rate and the effect of The Act on the Company's pension plans, derivative instruments, available-for-sale securities and cumulative translation adjustments. This reclassification is reflected in the "Adoption of accounting standards" line in the consolidated statements of equity. See Note 2 for additional information.

Prior to the Merger, the Company declared dividends of $1.38 per share in 2017 ($1.84 per share in 2016 and $1.72 per share in 2015)2016). Effective with the Merger, Dow no longer has publicly traded common stock. Dow's common shares are owned solely by its parent company, DowDuPont. As a result, the Company’s Board of Directors ("Board") determines whether or not there will be a dividend distribution to DowDuPont. See Note 24 for additional information.


NOTE 2 – RECENT ACCOUNTING GUIDANCE
Recently Adopted Accounting Guidance
In the first quarter of 2017, the Company adopted ASU 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting," which simplifies several aspects of the accounting for share-based payment awards to employees, including the accounting for income taxes, forfeitures, statutory tax withholding requirements and classification in the statement of cash flows. The new standard was effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Under the new guidance, excess tax benefits related to equity compensation are now recognized in "Provision for income taxes" in the consolidated statements of income rather than in "Additional paid-in capital" in the consolidated balance sheets and this change was applied on a prospective basis. Changes to the consolidated statements of cash flows related to the classification of excess tax benefits and employee taxes paid for share-based payment arrangements were implemented on a retrospective basis. See Note 1 for additional information.

In the fourth quarter of 2017,2018, the Company early adopted ASU 2017-04, "Intangibles2018-14, "Compensation - Goodwill and Other (Topic 350)Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): SimplifyingDisclosure Framework - Changes to the TestDisclosure Requirements for Goodwill Impairment.Defined Benefit Plans," The new guidance eliminates the requirement to determine the fair valuewhich, as part of individual assets and liabilities of a reporting unit to measure goodwill impairment. Under the amendments in the new guidance, goodwill impairment testing is performed by comparing the fair value of the reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. The new standard is effective for

Table of Contents


annual and interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and should be applied on a prospective basis. Early adoption was permitted for annual or interim goodwill impairment testing performed after January 1, 2017. The Company adopted the new guidance for goodwill impairment tests performed in the fourth quarter of 2017. See Note 13 for additional information.

Accounting Guidance Issued But Not Adopted at December 31, 2017
In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)," which is the new comprehensive revenue recognition standard that will supersede all existing revenue recognition guidance under U.S. GAAP. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to a customer in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which was issued in August 2015, revised the effective date for this ASU to annual and interim periods beginning on or after December 15, 2017, with early adoption permitted, but not earlier than the original effective date of annual and interim periods beginning on or after December 15, 2016, for public entities. Entities will have the option of using either a full retrospective approach or a modified approach to adopt the guidance in ASU 2014-09.

In May 2014, the FASB and International Accounting Standards Board formed The Joint Transition Resource Group for Revenue Recognition ("TRG"), consisting of financial statement preparers, auditors and users, to seek feedback on potential issues related to the implementation of the new revenue standard. As a result of feedback from the TRG, the FASB issued additional guidance to provide clarification, implementation guidance and practical expedients to address some of the challenges of implementation. In March 2016, the FASB issued ASU 2016-08, "Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)," which is an amendment on assessing whether an entity is a principal or an agent in a revenue transaction. This amendment addresses issues to clarify the principal versus agent assessment and lead to more consistent application. In April 2016, the FASB issued ASU 2016-10, "Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing," which contains amendments to the new revenue recognition standard on identifying performance obligations and accounting for licenses of intellectual property. The amendments related to identifying performance obligations clarify when a promised good or service is separately identifiable and allows entities to disregard itemsdisclosure framework project, removes disclosures that are immaterial inno longer considered cost beneficial, clarifies the contextspecific requirements of a contract. The licensing implementation amendments clarify how an entity should evaluate the nature of its promise in granting a license of intellectual property, which will determine whether revenue is recognized over time or at a point in time. In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvementscertain disclosures and Practical Expedients," which provides clarity and implementation guidance on assessing collectibility, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition. Theadds new standards have the same effective date and transition requirements as ASU 2014-09.

The Company analyzed the impact of ASU 2014-09, and the related ASU's, across all revenue streams to evaluate the impact of the new standard on revenue contracts. This included reviewing current accounting policies and practices to identify potential differences that would result from applying the requirements under the new standard. The Company completed contract reviews and validated the results of applying the new revenue guidance. The Company finalized its accounting policies, the evaluation of the impact of the accounting and disclosure requirements on its business processes, controls and systems, and is drafting new disclosures required post-implementation in 2018. The Company will adopt the new standard using the modified retrospective approach, under which the cumulative effect of initially applying the new guidance will be recognized as an adjustment to the opening balance of retained earnings in the first quarter of 2018. Based on the completed analysis, the Company has determined the adjustment will not have a material impact on the consolidated financial statements.

In January 2016, the FASB issued ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities," which amends the guidance under U.S. GAAP on the classification and measurement of financial instruments. Changes to the current guidance primarily affects the accountingthat are considered relevant for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the ASU clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities.employers that sponsor defined benefit pension and/or other postretirement benefit plans. The new standard is effective for fiscal years and interim periods beginningending after December 15, 2017, and upon adoption, an entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet at the beginning of the first reporting period in which the guidance is effective. Early adoption is not permitted except for the provision to record fair value changes for financial liabilities under the fair value option resulting from instrument-specific credit risk in other comprehensive income. The Company will adopt the new guidance in the first quarter of 2018 and the adoption of this guidance will not have a material impact on the consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, "Leases (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 with lease terms of more than twelve months and recognition, presentation and

measurement in the financial statements will depend on its classification as a finance or operating lease. In addition, the new guidance will require 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 current U.S. GAAP but does contain some targeted improvements to align with the new revenue recognition guidance issued in 2014. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, using a modified retrospective approach,2020, and early adoption is permitted. The Company has a team in place to evaluate the new guidance and is in the process of implementing a software solution to facilitate the development of business processes and controls around leases to meet the new accounting and disclosure requirements upon adoption in the first quarter of 2019.

In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments," which addresses the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows with respect to eight specific cash flow issues. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The amendments should be applied using a retrospective transition method to each period presented, if practicable. Early adoption is permitted, including adoption in an interim period, and any adjustments should be reflected as of the beginning of the fiscal year that includes the interim period. All amendments must be adopted in the same period. A key provision in the new guidance will impact the presentation of proceeds from interests in trade accounts receivable conduits which will be retrospectively reclassified from "Operating Activities" to "Investing Activities" in the consolidated statements of cash flows when the Company adopts the new guidance in the first quarter of 2018.

In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory," which requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, and should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings at the beginning period of adoption. Early adoption is permitted in the first interim period of an annual reporting period for which financial statements have not been issued. The Company will adopt the new guidance in the first quarter of 2018 and the adoption of this guidance will not have a material impact on the consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force)," which clarifies how entities should present restricted cash and restricted cash equivalents in the statement of cash flows, and, as a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. An entity with a material balance of restricted cash and restricted cash equivalents must disclose information about the nature of the restrictions. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted and the new guidance must be applied retrospectively to all periods presented. The new guidance will change the presentation of restricted cash in the consolidated statements of cash flows and will be applied retrospectively in the first quarter of 2018.

In February 2017, the FASB issued ASU 2017-05, "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and AccountingSee Note 19 for Partial Sales of Nonfinancial Assets," which clarifies the scope of guidance on nonfinancial asset derecognition in ASC 610-20 and the accountingupdated disclosures for partial sales of nonfinancial assets. The new guidance also conforms the derecognition guidance for nonfinancial assets with the model in the new revenue standard (ASU 2014-09). The new standard is effective for annual reporting periods, and interim periods within those fiscal years, beginning after December 15, 2017, and an entity is required to apply the amendments at the same time that it applies the amendments in ASU 2014-09. The Company will apply the new guidance with the implementation of the new revenue standard in the first quarter of 2018.

In March 2017, the FASB issued ASU 2017-07, "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," which amends the requirements related to the income statement presentation of the components of net periodic benefit cost for employer sponsored defined benefit pension and other postretirement benefit plans. Under

In the new guidance, an entity must disaggregate and present the service cost component of the net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period, and only the service cost component will be eligible for capitalization. Other components of net periodic benefit cost will be presented separately from the line item(s) that includes the service cost. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted at the beginning of an annual period in which the financial statements have not been issued. Entities must use a retrospective transition method to adopt the requirement for separate presentation of the income statement service cost and other components, and a prospective transition method to adopt the requirement to limit the capitalization of benefit cost to the service cost component. The Company will adopt the new guidance in the firstsecond quarter of 2018, using a retrospective transition method to reclassify net periodic benefit

cost, other than the service cost component, from "Cost of sales," "Research and development expenses" and "Selling, general and administrative expenses" to "Sundry income (expense) - net" in the consolidated statements of income.

In August 2017, the FASB issuedCompany early adopted ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities," which amends the hedge accounting recognition and presentation defined under ASCTopic 815, with the objectives of improving the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities and simplifying the application of hedge accounting by preparers. The new standard expands the strategies eligible for hedge accounting, relaxes the timing requirements of hedge documentation and effectiveness assessments, and permits, in certain cases, the use of qualitative assessments on an ongoing basis to assess hedge effectiveness. The new guidance also requires new disclosures and presentation. The new standard is effective for fiscal years, and interim periods

within those fiscal years, beginning after December 15, 2018. Early adoption is permitted in any interim or annual period after issuance of the ASU. Entities must adopt the new guidance by applying a modified retrospective approach to hedging relationships existing as of the adoption date. The adoption of the new guidance did not have a material impact on the consolidated financial statements.

In the second quarter of 2018, the Company early adopted ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income," which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from The Act, which was enacted on December 22, 2017, and requires certain disclosures about stranded tax effects. An entity has the option of applying the new guidance at the beginning of the period of adoption or retrospectively to each period (or periods) in which the tax effects related to items remaining in accumulated other comprehensive income are recognized. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, and early adoption is permitted, including adoption in an interim period for reporting periods in which the financial statements have not yet been issued. The Company's adoption of the new standard was applied prospectively at the beginning of the second quarter of 2018, with a reclassification of the stranded tax effects as a result of the The Act from accumulated other comprehensive loss to retained earnings. See Note 1 for additional information.

In the first quarter of 2018, the Company adopted ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)," which is the new comprehensive revenue recognition standard that supersedes the revenue recognition requirements in Topic 605, "Revenue Recognition," and most industry specific guidance. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to a customer in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In 2015 and 2016, the FASB issued additional ASUs related to Topic 606 that delayed the effective date of the guidance and clarified various aspects of the new revenue guidance, including principal versus agent considerations, identification of performance obligations, and accounting for licenses, and included other improvements and practical expedients. The new guidance was effective for annual and interim periods beginning after December 15, 2017. The Company elected to adopt the new guidance using the modified retrospective transition method for all contracts not completed as of the date of adoption. The Company recognized the cumulative effect of applying the new revenue standard as an adjustment to the opening balance of retained earnings at the beginning of the first quarter of 2018. The comparative periods have not been restated and continue to be accounted for under Topic 605. The adoption of the new guidance did not have a material impact on the consolidated financial statements. See Notes 1 and 4 for additional disclosures regarding the Company's contracts with customers as well as the impact of adopting Topic 606.

In the first quarter of 2018, the Company adopted ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities," which amends the guidance in U.S. GAAP on the classification and measurement of financial instruments. Changes to the current guidance primarily affects the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the ASU clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The new standard was effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company applied the amendments in the new guidance by means of a cumulative-effect adjustment to the opening balance of retained earnings at the beginning of the first quarter of 2018. The adoption of the new guidance did not have a material impact on the consolidated financial statements. See Notes 1 and 21 for additional information.

In the first quarter of 2018, the Company adopted ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments," which addresses diversity in practice in how certain cash receipts and cash payments are presented and classified in the statements of cash flows and addresses eight specific cash flow issues. The new standard was effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. A key provision in the new guidance impacted the presentation of proceeds from interests in certain trade accounts receivable conduits, which were retrospectively reclassified from "Operating Activities" to "Investing Activities" in the consolidated statements of cash flows. See Note 1 for additional information.

In the first quarter of 2018, the Company adopted ASU 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory," which requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The amendments were effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The new guidance was applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings at the beginning of the first quarter of 2018. The adoption of this guidance did not have a material impact on the consolidated financial statements. See Note 1 for additional information.

In the first quarter of 2018, the Company adopted ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash," which clarifies how entities should present restricted cash and restricted cash equivalents in the statements of cash flows, and as a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statements of cash flows. An entity with a material balance of restricted cash and restricted cash equivalents must disclose information about the nature of the restrictions. The new standard was effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The new guidance changed the presentation of restricted cash in the consolidated statements of cash flows and was implemented on a retrospective basis in the first quarter of 2018. See Note 1 for additional information.

In the first quarter of 2018, the Company adopted ASU 2017-07, "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," which amends the requirements related to the income statement presentation of the components of net periodic benefit cost for employer sponsored defined benefit pension and other postretirement benefit plans. Under the new guidance, an entity must disaggregate and present the service cost component of net periodic benefit cost in the same income statement line items as other employee compensation costs arising from services rendered during the period, and only the service cost component will be eligible for capitalization. Other components of net periodic benefit cost must be presented separately from the line items that includes the service cost. The new standard was effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Entities were required to use a retrospective transition method to adopt the requirement for separate income statement presentation of the service cost and other components, and a prospective transition method to adopt the requirement to limit the capitalization of benefit cost to the service component. Accordingly, in the first quarter of 2018, the Company used a retrospective transition method to reclassify net periodic benefit cost, other than the service component, from "Cost of sales," "Research and development expenses" and "Selling, general and administrative expenses" to "Sundry income (expense) - net" in the consolidated statements of income. See Note 1 for additional information.

Accounting Guidance Issued But Not Adopted at December 31, 2018
In February 2016, the 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 will depend on its classification as a finance or operating lease. In addition, the new guidance will require 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 current U.S. GAAP but does contain some targeted improvements to align with the new revenue recognition guidance issued in 2014 (Topic 606). The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, 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 a third-party software solution to facilitate compliance with accounting and reporting requirements. The team continues to review existing lease arrangements and has collected and loaded a significant portion of the lease portfolio into the software. The Company continues to enhance accounting systems and update business processes and controls related to the new guidance for leases. Collectively, these activities are expected to enable the Company to meet the new accounting and disclosure requirements upon adoption in the first quarter of 2019.

The ASU requires 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) the effective date or (2) the beginning of the earliest comparative period presented in the financial statements at the 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 will not be restated. In addition, the Company has elected the package of practical expedients permitted under the transition guidance, 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 will exclude short-term leases (term of 12 months or less) from the balance sheet presentation and will account for non-lease and lease components in a contract as a single lease component for all asset classes. The Company is finalizing the evaluation of the January 1, 2019, impact and estimates a material increase of lease-related assets and liabilities, ranging from $2.4 billion to $2.8 billion in the consolidated balance sheets. The impact to the Company's consolidated statements of income and consolidated statements of cash flows is not expected to be material.

In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement," which is part of the FASB disclosure framework project to improve the effectiveness of disclosures in the notes to the financial statements. The amendments in the new guidance remove, modify and

53

Table of Contents


add certain disclosure requirements related to fair value measurements covered in Topic 820, "Fair Value Measurement." The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for either the entire standard or only the requirements that modify or eliminate the disclosure requirements, with certain requirements applied prospectively, and all other requirements applied retrospectively to all periods presented. The Company is currently evaluating the impact of adopting this guidance.

In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract," which requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in Topic 350, "Intangibles - Goodwill and Other" to determine which implementation costs to capitalize as assets or expense as incurred. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted and an entity can elect to apply the new guidance on a prospective or retrospective basis. The Company is currently evaluating the impact of adopting this guidance.


NOTE 3 – MERGER WITH DUPONT
Effective August 31, 2017, Dow and DuPont completed the previously announced merger of equals transaction contemplated by the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017 (the "Merger Agreement"), by and among the Company, DuPont, DowDuPont, Diamond Merger Sub, Inc. and Orion Merger Sub, Inc. Pursuant to the Merger Agreement, (i) Diamond Merger Sub, Inc. was merged with and into Dow, with Dow surviving the merger as a subsidiary of DowDuPont (the "Diamond Merger") and (ii) Orion Merger Sub, Inc. was merged with and into DuPont, with DuPont surviving the merger as a subsidiary of DowDuPont (the "Orion Merger" and, together with the Diamond Merger, the "Mergers"). Following the consummation of the Mergers, each of Dow and DuPont became subsidiaries of DowDuPont (collectively, the "Merger"). Following the Merger, Dow and DuPont intend to pursue, subject to certain customary conditions, including, among others, the effectiveness of registration statements filed with the SEC and approval by the board of directors of DowDuPont ("DowDuPont Board"), the separation of the combined company's agriculture, business,materials science and specialty products business and materials science businessbusinesses through one or more tax-efficient transactions ("Intended Business Separations"). Additional information about the Merger is included in Current Reports on Form 8-K filed with the U.S. Securities and Exchange Commission ("SEC")SEC on December 11, 2015, March 31, 2017, August 4, 2017 and September 1, 2017.

Upon completion of the Diamond Merger, each share of common stock, par value $2.50 per share, of Dow ("Dow Common Stock") (excluding any shares of Dow Common Stock that were held in treasury immediately prior to the effective time of the Diamond 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"). As provided in the Merger Agreement, at the effective time of the Mergers, (i) all options, deferred stock, performance deferred stock and other equity awards relating to shares of Dow Common Stock outstanding immediately prior to the effective time of the Mergers were generally automatically converted into options and deferred stock and other equity awards relating to shares of DowDuPont Common Stock after giving effect to appropriate adjustments to reflect the Mergers and otherwise generally on the same terms and conditions as applied under the applicable plans and award agreements immediately prior to the effective time of the Mergers. See Note 20 for additional information on the conversion of the equity awards.

In the third quarter of 2017, as a result of the Diamond Merger and the Merger, the Company recorded a reduction in "Treasury stock" of $935 million, a reduction in "Common stock" of $3,107 million and an increase in "Additional paid in capital" of $2,172 million. At September 1, 2017, the Company has 100 shares of common stock issued and outstanding, par value $0.01 per share, owned solely by its parent, DowDuPont.

On August 31, 2017, following the Diamond Merger, Dow requested that the New York Stock Exchange ("NYSE") withdraw the shares of Dow Common Stock from listing on the NYSE and filed a Form 25 with the SEC to report that the shares of Dow Common Stock are no longer listed on the NYSE. The shares of Dow Common Stock were suspended from trading on the NYSE prior to the open of trading on September 1, 2017.

As a condition of the regulatory approval of the Merger, Dow and DuPont agreed to certain closing conditions, which are as follows:

Dow divested its global Ethylene Acrylic Acid copolymers and ionomers business ("EAA Business") to SK Global Chemical Co., Ltd., on September 1, 2017, as part of a divestiture commitment given to the European Commission ("EC") in connection with the EC's conditional approval of the Merger granted on March 27, 2017. See Note 56 for additional information on this transaction.

DuPont divested its Cereal Broadleaf Herbicides and Chewing Insecticides portfolios as well as its Crop Protection research and development ("R&D") pipeline and organization (excluding seed treatment, nematicides, late-stage R&D programs and certain personnel needed to support marketed products and R&D programs that will remain with DuPont) (collectively, the "DuPont Divested Assets") to FMC Corporation ("FMC") on November 1, 2017, as part of the EC's conditional approval granted on March 27, 2017. Also on November 1, 2017, DuPont completed its acquisition of FMC's Health and Nutrition business, excluding its Omega-3 products.

On May 2, 2017, Dow and DuPont announced that China's Ministry of Commerce ("MOFCOM") granted conditional regulatory approval for the companies' proposed merger of equals which included commitments already made to the EC including DuPont's divestiture of the DuPont Divested Assets and Dow's divestiture of the EAA Business. In addition, Dow and DuPont have made commitments related to the supply and distribution in China of certain herbicide and insecticide ingredients and formulations for rice crops for five years after the closing of the Merger.

Dow divested a select portion of Dow AgroSciences' corn seed business in Brazil ("DAS Divested Ag Business") to CITIC Agri Fund on November 30, 2017. The divestiture was part of the commitment given to Brazil's Administrative Council for Economic Defense ("CADE") in connection with the CADE's conditional approval of the Merger granted on May 17, 2017, which was incremental to commitments already made to the EC, China and regulatory agencies in other jurisdictions. See Note 56 for additional information on this transaction.

On June 15, 2017, Dow and DuPont announced that a proposed agreement had been reached with the Antitrust Division of the United States Department of Justice that permitted the companies to proceed with the proposed merger of equals transaction. The proposed agreement was consistent with commitments already made to the EC.

Intended Business Separations
In furtherance of the Intended Business Separations, Dow and DuPont are engaged in a series of internal reorganization and realignment steps (the “Internal Reorganization”) to realign their businesses into three subgroups: agriculture, materials science and specialty products. DowDuPont has also formed two wholly owned subsidiaries: Dow Holdings Inc. (“DHI”), 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. Following the separation and distribution of DHI, which is targeted to occur by April 1, 2019, DowDuPont, as the remaining company, which is referred to herein as “New DuPont,” will continue to hold the agriculture and specialty products businesses. New DuPont is then targeted to complete the separation and distribution of Corteva on June 1, 2019, resulting in New DuPont holding the specialty products businesses of DowDuPont. Following the distributions, DowDuPont will be known as DuPont.

As part of the Internal Reorganization, 1) the assets and liabilities of the materials science business will be transferred or conveyed to legal entities that then will be aligned under DHI, 2) the assets and liabilities of the agriculture business will be transferred or conveyed to legal entities that then will be aligned under Corteva, and 3) the assets and liabilities of the specialty products business will be transferred or conveyed to legal entities that then will be aligned with New DuPont. Following the Internal Reorganization, DowDuPont expects to distribute DHI and Corteva through separate, pro rata U.S. federal tax-free spin-offs in which DowDuPont stockholders, at such time, would receive shares of common stock of DHI and of Corteva.

Additional information is included in the Form 10 registration statements for the separation of DowDuPont's materials science business (filed as Dow Holdings Inc.) filed with the SEC on September 7, 2018, as amended on October 19, 2018 and November 19, 2018, and the agriculture business (filed as Corteva, Inc.) filed with the SEC on October 18, 2018, as amended on December 19, 2018.


NOTE 4 – REVENUE
Revenue Recognition
The majority of the Company's revenue is derived from product sales. In 2018, 99 percent of the Company's sales related to product sales (98 percent in 2017 and 99 percent in 2016). The remaining sales were primarily related to Dow's insurance operations and licensing of patents and technologies. As of January 1, 2018, the Company accounts for revenue in accordance with Topic 606, "Revenue from Contracts with Customers," except for revenue from Dow's insurance operations, which is accounted for in accordance with Topic 944, "Financial Services - Insurance."

Product Sales
Product sales consist of sales of the Company's products to manufacturers and distributors. The Company considers order confirmations or purchase orders, which in some cases are governed by master supply agreements, to be contracts with a customer.

55

Table of Contents


Product sale contracts are generally short-term contracts where the time between order confirmation and satisfaction of all performance obligations is less than one year. However, the Company has some long-term contracts which can span multiple years.

Revenues from product sales are 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. 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.

Certain long-term contracts include a series of distinct goods that are delivered continuously to the customer through a pipeline (e.g., feedstocks). For these types of product sales, the Company invoices the customer in an amount that directly corresponds with the value to the customer of the Company’s performance to date. As a result, the Company recognizes revenue based on the amount billable to the customer in accordance with the right to invoice practical expedient.

The transaction price includes estimates for reductions in revenue from customer rebates and right of returns on product sales. These amounts are estimated based upon the most likely amount of consideration to which the customer will be entitled. The Company’s obligation for right of returns is limited primarily to the Seed principal product group. 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. 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.

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.

Patents, Trademarks and Licenses
The Company enters into licensing arrangements in which it licenses certain rights of its patents and technology to customers. Revenue from the majority of the Company’s licenses for patents and technology is derived from sales-based royalties. The Company estimates the amount of sales-based royalties it expects to be entitled to based on historical sales to the customer. For the remaining revenue from licensing arrangements, payments are typically received from the Company’s licensees based on billing schedules established in each contract. Revenue is recognized by the Company when the performance obligation is satisfied.

Remaining Performance Obligations
Remaining performance obligations represent the transaction price allocated to unsatisfied or partially unsatisfied performance obligations. At December 31, 2018, the Company had remaining performance obligations related to material rights granted to customers for contract renewal options of $102 million and unfulfilled performance obligations for the licensing of technology of $407 million. The Company expects revenue to be recognized for the remaining performance obligations over the next one to six years.

The remaining performance obligations are for product sales that have expected durations of one year or less, product sales of materials delivered through a pipeline for which the Company has elected the right to invoice practical expedient, or variable consideration attributable to royalties for licenses of patents and technology. The Company has received advance payments from customers related to long-term supply agreements that are deferred and recognized over the life of the contract, with remaining contract terms that range up to 22 years. The Company will have rights to future consideration for revenue recognized when product is delivered to the customer. These payments are included in "Accrued and other current liabilities" and "Other noncurrent obligations" in the consolidated balance sheets.

Disaggregation of Revenue

Asset write-downs and write-offs in the second quarter of 2015 totaled $169 million. Details regarding the write-downs and write-offs are as follows:

As a result of changing market dynamics in certain end-use markets, select manufacturing facilities and non-core assets aligned with electronics and imaging products were shut down in 2016. The assets impacted included certain display films and metalorganic precursors, including a metalorganic materials manufacturing site in North Andover, Massachusetts, and related operations in Taoyuan, Taiwan, as well as certain display films’ manufacturing assets aligned with SKC Haas Display Films Co., Ltd., a former majority-owned joint venture located in Cheonan, South Korea. The Company recorded a $51 million charge for asset write-downs and write-offs.

A photovoltaic plant in Schkopau, Germany, was permanently shut down in the second quarter of 2015, resulting in an asset write-off of $12 million.

Select operations for seed and crop protection products were shut down, closed or idled in the second half of 2015, resulting in a pretax charge of $8 million for the write-down of assets.

Costs Associated with Exit and Disposal Activities
The restructuring charges for costs associated with exit and disposal activities, primarily environmental remediation and contract penalties, totaled $10 million in the second quarter of 2015.

Dow expects to incur additional costs in the future related to its restructuring activities. Future costs are expected to include demolition costs related to closed facilities and restructuring plan implementation costs; these costs will be recognized as incurred. The Company also expects to incur additional employee-related costs, including involuntary termination benefits, related to its other optimization activities. These costs cannot be reasonably estimated at this time.

Goodwill Impairment
Upon completion of the goodwill impairment testing in the fourth quarter of 2017, the Company determined the fair value of the Coatings & Performance Monomers reporting unit was lower than its carrying amount. As a result, the Company recorded an impairment charge of $1,491 million in the fourth quarter of 2017, included in “Restructuring, goodwill impairment and asset related charges - net” in the consolidated statements of income. See Note 13 for additional information on the impairment charge.

2017 Charges
In the fourth quarter of 2017, the Company recognized a $622 million pretax impairment charge related to a biopolymers manufacturing facility in Santa Vitoria, Minas Gerais, Brazil. The Company determined it willwould not pursue an expansion of the facility’s ethanol mill into downstream derivative products, primarily as a result of cheaper ethane-based production as well as the Company’s new assets coming online inon the U.S. Gulf Coast which can be used to meet growing market demands in Brazil. As a result of this decision, cash flow analysis indicated the carrying amount of the impacted assets was not recoverable. The impairment charge was included in “Restructuring, goodwill impairment and asset related charges - net” in the consolidated statements of income. See Notes 22 and 23 for additional information.

The Company also recognized other pretax impairment charges of $317 million in the fourth quarter of 2017, including charges related to manufacturing assets of $230 million, an equity method investment of $81 million and other assets of $6 million.

NOTE 7 – REVERSE MORRIS TRUST TRANSACTION
On October 5, 2015, (i) the Company completed the transfer of its U.S. Gulf Coast Chlor-Alkali and Vinyl, Global Chlorinated Organics and Global Epoxy businesses ("chlorine value chain") into a new company ("Splitco"), (ii) participating Dow shareholders tendered, and the Company accepted, Dow shares for Splitco shares in a public exchange offer, and (iii) Splitco merged with a wholly owned subsidiary of Olin Corporation ("Olin") in a tax-efficient Reverse Morris Trust transaction (collectively, the “Transaction”). The Transaction was subject to Olin shareholder approval, customary regulatory approvals, tax authority rulings including a favorable private letter ruling from the U.S. Internal Revenue Service which confirms the Transaction to be substantially free of U.S. federal income tax, and expiration of the public exchange offer. Dow does not have an ownership interest in Olin as a result of the Transaction.

Under the terms of a debt exchange offer, Dow received $1,220 million principal amount of new debt instruments from Splitco, which were subsequently transferred to certain investment banks in a non-cash fair value exchange for $1,154 million principal amount of the Company’s outstanding debt instruments owned by such investment banks. As a result of this debt exchange offer and related transactions, the Company retired $1,161 million of certain notes and recognized a $68 million loss on the early extinguishment of debt, included in "Sundry income (expense) - net" in the consolidated statements of income and included as a component of the pretax gain on the Transaction. See Note 15 for additional information on the early extinguishment of debt.

Table of Contents


Dow shareholders who elected to participate in the public exchange offer tendered 34.1 million shares of Dow common stock in exchange for 100 million shares of Splitco. Following the merger of Splitco with Olin, each share of Splitco common stock was automatically converted to the right to receive 0.87482759 shares of Olin common stock, or 87.5 million shares, which represented approximately 52.7 percent of Olin’s common stock outstanding. As a result of this non-cash share exchange offer, the Company recorded an increase of $1,523 million in “Treasury Stock” in the consolidated statements of equity, which is valued based on Dow’s opening stock price on October 5, 2015. The Company’s outstanding common shares were reduced by 3 percent as a result of the Transaction.

Under the terms of the Transaction, Dow received cash proceeds of $875 million in the form of a one-time special payment from Splitco from proceeds received from a term loan and included in "Proceeds from issuance of long-term debt" in the consolidated statements of cash flows. The Company also received a $434 million advance payment from Olin, included in "Other assets and liabilities, net" in the consolidated statements of cash flows, related to a long-term ethylene supply agreement, of which $16 million was classified as "Accrued and other current liabilities" and $418 million was classified as "Other noncurrent obligations" in the consolidated balance sheets at the time of receipt. The Transaction also resulted in numerous long-term supply, service and purchase agreements between Dow and Olin.

In connection with the Transaction, the Company purchased Mitsui & Co. Texas Chlor-Alkali Inc.’s (“Mitsui”) 50 percent equity interest in a membrane chlor-alkali joint venture (“JV Entity”), which resulted in Dow becoming the sole equity owner of the JV Entity. The Company purchased Mitsui's equity interest for $133 million, which resulted in a loss of $25 million included in "Sundry income (expense) - net" in the consolidated statements of income and included as a component of the pretax gain on the Transaction. The JV Entity was included in the transfer of the chlorine value chain to Splitco. See Note 23 for further information on the acquisition of Mitsui’s equity interest in the JV Entity.

The Company also transferred $439 million of net unfunded defined pension and other postretirement benefit obligations in the United States and Germany to Olin.

In the fourth quarter of 2015, the Company completed the split-off of the chlorine value chain for $3,510 million, net of working capital adjustments and costs to sell, with proceeds subject to post-closing adjustments. The proceeds included cash received from Splitco in the form of a one-time special payment from proceeds received from a term loan, the principal amount of the Splitco debt included in the debt exchange offer and the market value of the Dow common shares tendered in the public exchange offer. The Company recognized a pretax gain of $2,233 million on the Transaction, included in "Sundry income (expense) - net" in the consolidated statements of income, which is the excess of the sum of the net proceeds received over the chlorine value chain's net book value, a loss on the early extinguishment of debt and a loss on the acquisition of Mitsui's noncontrolling interest. The Company recognized an after-tax gain of $2,215 million, primarily due to the tax-efficient nature of the Transaction.

In 2016, the Company recognized a pretax gain of $6 million for post-closing adjustments, including a $5 million reduction to the net unfunded defined pension and other postretirement benefit obligation. The gain was included in "Sundry income (expense) - net" in the consolidated statements of income. See Note 19 for additional information.

In 2017, the Company recognized a pretax gain of $7 million for post-closing adjustments. The gain was included in "Sundry income (expense) - net" in the consolidated statements of income.

The Company did not report the historical results of the chlorine value chain as discontinued operations in Dow's financial statements as the divestiture of these businesses did not represent a strategic shift that had a major effect on the Company's operations and financial results. However, the chlorine value chain was considered an individually significant component and select income statement information is presented below:

NOTE 9 – INCOME TAXES
On December 22, 2017, the Tax Cuts and JobsThe Act (“The Act”) was enacted. The Act reduces the U.S. federal corporate income tax rate from 35 percent to 21 percent, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously deferred, creates new provisions related to foreign sourced earnings, eliminates the domestic manufacturing deduction and moves to a hybrid territorial system. At December 31, 2017, the Company had not completed its accounting for the tax effects of The Act; however, as described below, the Company made a reasonable estimate of the effects on its existing deferred

AsIn 2017, as a result of the Merger and subsequent change in the Company's ownership, certain net operating loss carryforwards available for the Company’s consolidated German tax group were derecognized. In addition, the sale of stock between two consolidated subsidiaries in 2014 created a gain that was initially deferred for tax purposes. This deferred gain became taxable as a result of activities executed in anticipation of the Intended Business Separations. As a result, in 2017, the Company decreased “Deferred income tax assets” in the consolidated balance sheets and recorded a charge of $267 million to “Provision for income taxes” in the consolidated statements of income of $267 million.income.

1.The 2016 balance includes the impact of a settlement agreement related to a historical change in the legal ownership structure of a nonconsolidated affiliate discussed below.
2.The 2016 balance includes $126 million assumed in the DCC Transaction.Dow Silicones ownership restructure.

On January 9, 2017, the U.S. Supreme Court denied certiorari in the Company’s tax treatment of partnerships and transactions associated with Chemtech, a wholly owned subsidiary. The Company has fully accrued the position and does not expect a future impact to “Provision for income taxes” in the consolidated statements of income as a result of the ruling.

In the fourth quarter of 2016, a settlement of $206 million was reached on a tax matter associated with a historical change in the legal ownership structure of a nonconsolidated affiliate. As a result of the settlement, the Company recorded a net decrease in uncertain tax positions of $67 million, included in “Other noncurrent obligations” in the consolidated balance sheets, and an unfavorable impactcharge of $13 million to “Provision for income taxes” in the consolidated statements of income.

Dow and its consolidated subsidiaries are included in DowDuPont's consolidated federal income tax group and consolidated tax return. Generally, the consolidated tax liability of the DowDuPont U.S. tax group for each year will be apportioned among the members of the consolidated group based on each member’s separate taxable income. Dow and DuPont 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 a tax sharing agreement and/or tax matters agreement.

Each year, the Company files 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 impact on the Company’s resultsultimate resolution of operationssuch uncertainties is not expected to be material.have a material impact on the Company's results of operations.

The reserve for non-income tax contingencies related to issues in the United States and foreign locations was $91 million at December 31, 2018 and $110 million at December 31, 2017 and $108 million at December 31, 2016.2017. This is management’s best estimate of the potential liability for non-income tax contingencies. Inherent uncertainties exist in estimates of tax contingencies due to changes in tax law, both legislated and concluded through the various jurisdictions’ tax court systems. It is the opinion of the Company’s management that the possibility is remote that costs in excess of those accrued will have a material impact on the Company’s consolidated financial statements.

Effective with the Merger, the Company updated its reporting units to align with the level at which discrete financial information is available for review by management. A relative fair value method was used to reallocate goodwill for reporting units of which the composition had changed. The new reporting units are: Agriculture, Coatings & Performance Monomers, Construction Chemicals, Consumer Solutions, Electronics & Imaging, Energy Solutions, Hydrocarbons & Energy, Industrial Biosciences, Industrial Solutions, Nutrition & Health, Packaging and Specialty Plastics, Polyurethanes & CAV, Safety & Construction and Transportation & Advanced Polymers. At December 31, 2017, goodwill was carried by all of these reporting units.

In 2018, the Energy Solutions and Construction Chemicals reporting units were combined into Industrial Solutions and Polyurethanes & CAV, respectively. At December 31, 2018, goodwill was carried by all reporting units.

Goodwill Impairments
The carrying amounts of goodwill at December 31, 20172018 and 20162017, were net of accumulated impairments of $1,920 million and $429 million, respectively.million.

Goodwill Impairment Testing
The Company performs an impairment test of goodwill annually in the fourth quarter. In the fourth quarter of 2017, the Company early adopted ASU 2017-04. See Note 2 for additional information.

In 2017,2018, the Company performed quantitative testing for 112 reporting units (3(11 in 20162017 and 3 in 2015)2016) and a qualitative assessment was performed for the remaining reporting units. The qualitative assessmentassessments indicated that it was not more likely than not that fair value was less than the carrying value for those reporting units included in the qualitative test.

The quantitative testing conducted in 2018 and 2016 concluded that no goodwill impairments existed.

Upon completion of the quantitative testing in the fourth quarter of 2017, the Company determined the Coatings & Performance Monomers reporting unit was impaired. Throughout 2017, the Coatings & Performance Monomers reporting unit did not

consistently meet expected financial performance targets, primarily due to increasing commoditization in coatings markets and competition, as well as customer consolidation in end markets which reduced growth opportunities. As a result, the Coatings & Performance Monomers reporting unit lowered future revenue and profitability expectations. The fair value of the Coatings & Performance Monomers reporting unit was determined using a discounted cash flow methodology that reflected reductions in projected revenue growth rates, primarily driven by modified sales volume and pricing assumptions, as well as revised expectations for future growth rates. These discounted cash flows did not support the carrying value of the Coatings & Performance Monomers reporting unit. As a result, the Company recorded a goodwill impairment charge for the Coatings & Performance Monomers reporting unit of $1,491 million in the fourth quarter of 2017, included in “Restructuring, goodwill impairment and asset related charges - net” in the consolidated statements of income. The Coatings & Performance Monomers reporting unit carried $1,071 million of goodwill at December 31, 2017.

No other goodwill impairments were identified as a result of the 2017 testing. Impairment tests conducted in 2016 and 2015 concluded that no goodwill impairments existed.

NOTE 14 – TRANSFERS OF FINANCIAL ASSETS
The Company sellshas historically sold trade accounts receivable of select North American entities and qualifying trade accounts receivable of select European entities on a revolving basis to certain multi-seller commercial paper conduit entities ("conduits"). The proceeds received are comprised of cash and interests in specified assets of the conduits (the receivables sold by the Company) that entitle the Company to the residual cash flows of such specified assets in the conduits after the commercial paper has been repaid. Neither the conduits nor the investors in those entities have recourse to other assets of the Company in the event of nonpayment by the debtors.

In the fourth quarter of 2017, the Company suspended further sales of trade accounts receivable through these facilities and began reducing outstanding balances under these facilities through collections of trade accounts receivable previously sold to such conduits. The Company hasIn September and October 2018, the ability to resume such sales toNorth American and European facilities, respectively, were amended and the conduits, subject to certain prior notice requirements, at the discretionterms of the Company.agreements changed from off-balance sheet arrangements to secured borrowing arrangements. See Note 15 for additional information on the secured borrowing arrangements.

For the year ended December 31, 2017,2018, the Company recognized a loss of $25$7 million on the sale of these receivables ($2025 million loss for the year ended December 31, 20162017 and $15$20 million loss for the year ended December 31, 2015)2016), which is included in “Interest expense and amortization of debt discount” in the consolidated statements of income.

The Company's interests in the conduits are carried at fair value and included in “Accounts and notes receivable – Other” in the consolidated balance sheets. Fair value of the interests is determined by calculating the expected amount of cash to be received and is based on unobservable inputs (a Level 3 measurement). The key input in the valuation is the percentage of anticipated credit losses in the portfolio of receivables sold that have not yet been collected. Given the short-term nature of the underlying receivables, discount rates and prepayments are not factors in determining the fair value of the interests.

The following table summarizes the carrying value of interests held, which represents the Company's maximum exposure to loss related to the receivables sold, and the percentage of anticipated credit losses related to the trade accounts receivable sold. Also provided is the sensitivity of the fair value of the interests held to hypothetical adverse changes in the anticipated credit losses; amounts shown below are the corresponding hypothetical decreases in the carrying value of interests.

Term Loan Facility
In connection with the DCC Transaction,ownership restructure of Dow Silicones on May 31, 2016, Dow CorningSilicones incurred $4.5 billion of indebtedness under a certain third party credit agreement ("DCC Term Loan Facility"). The Company subsequently guaranteed the obligations of Dow CorningSilicones under the DCC Term Loan Facility and, as a result, the covenants and events of default applicable to the DCC Term Loan Facility are substantially similar to the covenants and events of default set forth in the Company's Five Year Competitive Advance and Revolving Credit Facility. In the second quarter of 2017,2018, Dow CorningSilicones exercised a 364-daythe 19-month extension option making amounts borrowed under the DCC Term Loan Facility repayable on May 29, 2018, andDecember 30, 2019. In addition, Dow Silicones amended the DCC Term Loan Facility to include an additional 19-month2-year extension option, at Dow Corning'sSilicones' election, upon satisfaction of certain customary conditions precedent. On February 8, 2018, Dow Corning delivered a notice of intentSilicones intends to exercise the 19-month2-year extension option on the DCC Term Loan Facility.

In September 2018, the Company renewed its North American accounts receivable securitization facility for a one year term and amended the terms of the agreement from an off-balance sheet arrangement to a secured borrowing arrangement, with a borrowing capacity up to $800 million. Under the structure of the amended agreement, the Company will use select trade accounts receivable to collateralize the credit facility with certain lenders. At December 31, 2018, the facility had not been drawn upon.
In October 2018, the Company renewed its European accounts receivable securitization facility for a two year term and amended the terms of the agreement from an off-balance sheet arrangement to a secured borrowing arrangement, with a borrowing capacity up to Euro 400 million. Under the structure of the amended agreement, the Company will use select trade accounts receivable to collateralize the credit facility with certain lenders. At December 31, 2018, the facility had not been drawn upon.

Uncommitted Credit Facilities and Outstanding Letters of Credit
The Company had uncommitted credit facilities in the form of unused bank credit lines of $2,853approximately $3,480 million at December 31, 2017.2018. These lines can be used to support short-term liquidity needs and general purposes, including letters of credit. Outstanding letters

of credit were $433$439 million at December 31, 2017.2018 ($433 million at December 31, 2017). These letters of credit support commitments made in the ordinary course of business.

Debt Covenants and Default Provisions
The Company’s outstanding long-term debt has been issued primarily under indentures which contain, among other provisions, certain customary restrictive covenants with which the Company must comply while the underlying notes are outstanding. Failure of the Company to comply with any of its covenants, could result in a default under the applicable indenture and allow the note holders to accelerate the due date of the outstanding principal and accrued interest on the underlying notes.

The Company's indenture covenants include obligations to not allow liens on principal U.S. manufacturing facilities, enter into sale and lease-back transactions with respect to principal U.S. manufacturing facilities, merge or consolidate with any other corporation, or sell, lease or convey, directly or indirectly, all or substantially all of the Company’s assets. The outstanding debt also contains customary default provisions. The Company remains in compliance with these covenants after the Merger.

The Company’s primary, private credit agreements also contain certain customary restrictive covenant and default provisions in addition to the covenants set forth above with respect to the Company’s debt. Significant other restrictive covenants and default provisions related to these agreements include:

(a)the obligation to maintain the ratio of the Company’s consolidated indebtedness to consolidated capitalization at no greater than 0.65 to 1.00 at any time the aggregate outstanding amount of loans under the Five Year Competitive Advance and Revolving Credit Facility Agreement dated March 24, 2015,October 30, 2018, equals or exceeds $500 million,

(b)a default if the Company or an applicable subsidiary fails to make any payment, including principal, premium or interest, under the applicable agreement on other indebtedness of, or guaranteed by, the Company or such applicable subsidiary in an aggregate amount of $100 million or more when due, or any other default or other event under the applicable agreement with respect to such indebtedness occurs which permits or results in the acceleration of $400 million or more in the aggregate of principal, and

(c)a default if the Company or any applicable subsidiary fails to discharge or stay within 60 days after the entry of a final judgment against the Company or such applicable subsidiary of more than $400 million.

Failure of the Company to comply with any of the covenants or default provisions could result in a default under the applicable credit agreement which would allow the lenders to not fund future loan requests and to accelerate the due date of the outstanding principal and accrued interest on any outstanding indebtedness.

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 approximately two times that amount. 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. It is the opinion of the Company’s management, however, that the possibility is remote that costs in excess of the range disclosed will have a material impact on the Company’s results of operations, financial condition or 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, 2016,2017, the Company had accrued obligations of $909$878 million for probable environmental remediation and restoration costs, including $151$152 million for the remediation of Superfund sites.

In the fourth quarter of 2016, the Company recorded a pretax charge of $295 million for environmental remediation at a number of historical locations, including the Midland manufacturing site/off-site matters and the Wood-Ridge sites, primarily resulting from the culmination of negotiations with regulators and/or final agency approval. These charges were included in "Cost of sales" in the consolidated statements of income and were included in the total accrued obligation of $909 million at December 31, 2016.

Capital expenditures for environmental protection were $76 million in 2018, $79 million in 2017 and $66 million in 2016 and $49 million in 2015.2016.

Midland Off-Site Environmental Matters
On June 12, 2003, the Michigan Department of Environmental Quality ("MDEQ") issued a Hazardous Waste Operating License (the "License") to the Company’s Midland, Michigan manufacturing site (the “Midland site”), which was renewed and replaced by the MDEQ on September 25, 2015, and included provisions requiring the Company to conduct an investigation to determine the nature and extent of off-site contamination in the City of Midland soils, the Tittabawassee River and Saginaw River sediment and floodplain soils, and the Saginaw Bay, and, if necessary, undertake remedial action.

City of Midland
On March 6, 2012, In 2016, final regulatory approval was received from the Company submitted an Interim Response Activity Plan Designed to Meet Criteria ("Work Plan") to the MDEQ that involved the sampling of soil at residential properties near the Midland site for the presence of dioxins to determine where clean-up may be required and then conducting remediation for properties that sampled above the remediation criteria. The MDEQ approved the Work Plan on June 1, 2012 and implementation of the Work Plan began on June 4, 2012. The Company also submitted and had approved by the MDEQ, amendments to the Work Plan. At December 31, 2014, remediation was completed on all 132 properties that tested above the remediation criteria, and this completion is noted in the License. On July 21, 2016, the MDEQ approved a Corrective Action report, including a Remedial Action Plan ("RAP"), for the City of Midland. This is the final regulatory approval required for the City of Midland.Midland and Dow is implementingcontinuing the long term monitoring and maintenance requirements of the RAP.Remedial Action Plan.

Tittabawassee and Saginaw Rivers, Saginaw Bay
The Company, the U.S. Environmental Protection Agency (“EPA”) and the State of Michigan ("State") entered into an administrative order on consent (“AOC”), effective January 21, 2010, that requires the Company to conduct a remedial investigation, a feasibility study and a remedial design for the Tittabawassee River, the Saginaw River and the Saginaw Bay, and pay the oversight costs of the EPA and the State under the authority of the Comprehensive Environmental Response, Compensation, and Liability Act. These actions, to be conducted under the lead oversight of the EPA, will build upon the investigative work completed under the State Resource Conservation Recovery Act program from 2005 through 2009.

The Tittabawassee River, beginning at the Midland Site and extending down to the first six miles of the Saginaw River, are designated as the first Operable Unit for purposes of conducting the remedial investigation, feasibility study and remedial design work. This work will be performed in a largely upriver to downriver sequence for eight geographic segments of the Tittabawassee and upper Saginaw Rivers. In the first quarter of 2012, the EPA requested the Company address the Tittabawassee River floodplain ("Floodplain") as an additional segment. In January 2015, the Company and the EPA entered into an order to address remediation of the Floodplain. The remedial work is expected to take place over the next fivethree years. The remainder of the Saginaw River and the Saginaw Bay are designated as a second Operable Unit and the work associated with that unit may also be geographically segmented. The AOC does not obligate the Company to perform removal or remedial action; that action can only be required by a separate order. The Company and the EPA have been negotiating orders separate from the AOC that obligate the Company to perform remedial actions under the scope of work of the AOC. The Company and the EPA have entered into four separate orders to perform limited remedial actions in five of the eight geographic segments in the first Operable Unit, and the order to address the Floodplain.

Alternative Dispute Resolution Process
The Company, the EPA, the U.S. Department of Justice ("DOJ"), and the natural resource damage trustees (which include the Michigan Office of the Attorney General, the MDEQ, the U.S. Fish and Wildlife Service, the U.S. Bureau of Indian Affairs

and the Saginaw-Chippewa tribe) have been engaged in negotiations to seek to resolve potential governmental claims against the Company related to historical off-site contamination associated with the City of Midland, the Tittabawassee and Saginaw Rivers and the Saginaw Bay. The Company and the governmental parties started meeting in the fall of 2005 and entered into a Confidentiality Agreement in December 2005. The Company continues to conduct negotiations under the Federal Alternative Dispute Resolution Act with all of the governmental parties, except the EPA which withdrew from the alternative dispute resolution process on September 12, 2007.

On September 28, 2007, the Company and the natural resource damage trustees entered into a Funding and Participation Agreement that addressed the Company’s payment of past costs incurred by the natural resource damage trustees, payment of the costs of a trustee coordinator and a process to review additional cooperative studies that the Company might agree to fund or conduct with the natural resource damage trustees. On March 18, 2008, the Company and the natural resource damage trustees entered into a Memorandum of Understanding ("MOU") to provide a mechanism for the Company to fund cooperative studies related to the assessment of natural resource damages. This MOU was amended and funding of cooperative studies was extended until March 2014. All cooperative studies have been completed. On April 7, 2008, the natural resource damage trustees released their “Natural Resource Damage Assessment Plan for the Tittabawassee River System Assessment Area.”

At December 31, 2017,2018, the accrual for these off-site matters was $95 million (included in the total accrued obligation of $820 million). At December 31, 2017, the Company had an accrual for these off-site matters of $83 million (included in the total accrued obligation of $878 million). At December 31, 2016, the Company had an accrual for these off-site matters of $93 million (included in the total accrued obligation of $909 million).

Environmental Matters Summary
It is the opinion of the Company’s management that the possibility is remote that costs in excess of those disclosed will have a material impact on the Company’s results of operations, financial condition or cash flows.

Litigation
Asbestos-Related Matters of Union Carbide Corporation
Introduction
Union Carbide is and has been involved in a large number of asbestos-related suits filed primarily in state courts during the past four decades. These suits principally allege personal injury resulting from exposure to asbestos-containing products and frequently seek both actual and punitive damages. The alleged claims primarily relate to products that Union Carbide sold in the past, alleged exposure to asbestos-containing products located on Union Carbide’s premises, and Union Carbide’s responsibility for asbestos suits filed against a former Union Carbide subsidiary, Amchem.Amchem Products, Inc. ("Amchem"). In many cases, plaintiffs are unable to demonstrate that they have suffered any compensable loss as a result of such exposure, or that injuries incurred in fact resulted from exposure to Union Carbide’s products.

Union Carbide expects more asbestos-related suits to be filed against Union Carbide and Amchem in the future, and will aggressively defend or reasonably resolve, as appropriate, both pending and future claims.

Estimating the Liability for Asbestos-Related Pending and Future ClaimsLiability
Based on a study completed in January 2003 by Ankura Consulting Group, LLC ("Ankura"), Union Carbide increased its December 31, 2002 asbestos-related liability for pending and future claims for a 15-year period ending in 2017 to $2.2 billion, excluding future defense and processing costs. Since then, Union Carbide has compared current asbestos claim and resolution activity to the results of the most recent Ankura study at each balance sheet date to determine whether the accrual continues to be

appropriate. In addition, Union Carbide has requested Ankura to review Union Carbide’s historical asbestos claim and resolution activity each year since 2004 to determine the appropriateness of updating the most recent Ankura study.

In October 2016, Union Carbide requested Ankura to review its historical asbestos claim and resolution activity and determine the appropriateness of updating its December 2014 study. In response to the request, Ankura reviewed and analyzed asbestos-related claim and resolution data through September 30, 2016. The resulting study, completed by Ankura in December 2016, provided estimates for the undiscounted cost of disposing of pending and future claims against Union Carbide and Amchem, excluding future defense and processing costs, for both a 15-year period and through the terminal year of 2049.

Based on the study completed in December 2016 by Ankura, and Union Carbide's own review, of the asbestos claim and resolution activity, it was determined that an adjustment to the accrual was necessary.necessary. Union Carbide determined that using the estimate through the terminal year of 2049 was more appropriate due to increasing knowledge and data about the costs to resolve claims and diminished volatility in filing rates. Using the range in the Ankura December 2016 study, which was estimated to be betweenbetween $502 million and $565 million forfor the undiscounted cost of disposing of pending and future claims, Union Carbide increased its asbestos-related liability for pending and future claims through the terminal year of 2049 by $104 million, includedincluded in "Asbestos-related charge" in the consolidated statements of income. At December 31, 2016, Union Carbide's asbestos-related liability for

79

Table of Contents


pending and future claims was $486 million, and approximately 14 percent of the recorded liability related to pending claims and approximately 86 percent related to future claims.

Estimating the Asbestos-Related Liability for Defense and Processing Costs
In September 2014, Union Carbide began to implement a strategy designed to reduce and to ultimately stabilize and forecast defense costs associated with asbestos-related matters. The strategy included a number of important changes including: invoicing protocols including capturing costs by plaintiff; review of existing counsel roles, work processes and workflow; and the utilization of enterprise legal management software, which enabled claim-specific tracking of asbestos-related defense and processing costs. Union Carbide reviewed the information generated from this new strategy and determined that it now had the ability to reasonably estimate asbestos-related defense and processing costs for the same periods that it estimates its asbestos-related liability for pending and future claims. Union Carbide believes that including estimates of the liability for asbestos-related defense and processing costs provides a more complete assessment and measure of the liability associated with resolving asbestos-related matters, which Union Carbide and the Company believe is preferable in these circumstances.

In October 2016, in addition to the study for asbestos claim and resolution activity, Union Carbide requested Ankura to review asbestos-related defense and processing costs and provide an estimate of defense and processing costs associated with resolving pending and future asbestos-related claims facing Union Carbide and Amchem for the same periods of time that Union Carbide uses for estimating resolution costs. In December 2016, Ankura conducted the study and provided Union Carbide with an estimate of future defense and processing costs for both a 15-year period and through the terminal year of 2049. The resulting study estimated asbestos-related defense and processing costs for pending and future asbestos claims to be between $1,009 million and $1,081 million through the terminal year of 2049.

In the fourth quarter of 2016, Union Carbide and the Company elected to change their method of accounting for asbestos-related defense and processing costs from expensing as incurred to estimating and accruing a liability. This change is believed to be preferable as asbestos-related defense and processing costs represent expenditures related to legacy activities that do not contribute to current or future revenue generating activities of the Company. The change is also reflective of the manner in which Union Carbide manages its asbestos-related exposure, including careful monitoring of the correlation between defense spending and resolution costs. Together, these two sources of cost more accurately represent the “total cost” of resolving asbestos-related claims now and in the future.

This accounting policy change was reflected as a change in accounting estimate effected by a change in accounting principle. As a result of this accounting policy change and based on the December 2016 Ankura study of asbestos-related defense and processing costs and Union Carbide's own review of the data, Union Carbide recorded a pretax charge for asbestos-related defense and processing costs of $1,009 million in the fourth quarter of 2016, included in “Asbestos-related charge” in the consolidated statements of income. Union Carbide’s total asbestos-related liability, including defense and processing costs, was $1,490 million at December 31, 2016, and was included in “Accrued and other current liabilities” and “Asbestos-related liabilities - noncurrent” in the consolidated balance sheets.

Asbestos-Related Liability at December 31, 2017
In October 2017, Union Carbide requested Ankura to review its historical asbestos claim and resolution activity (including asbestos-related defense and processing costs) and determine the appropriateness of updating its December 2016 study. In response to that request, Ankura reviewed and analyzed data through September 30, 2017. In December 2017, Ankura stated that an update of its December 2016 study would not provide a more likely estimate of future events than the estimate reflected in the study and, therefore, the estimate in that study remained applicable. Based on Union Carbide's own review of the asbestos claim and resolution activity (including asbestos-related defense and processing costs) and Ankura's response, Union Carbide determined that no change to the accrual was required. At December 31, 2017, the asbestos-related liability for pending and future claims against Union Carbide and Amchem, including future asbestos-related defense and processing costs, was $1,369 million, and approximately 16 percent of the recorded liability related to pending claims and approximately 84 percent related to future claims.

In October 2018, Union Carbide requested Ankura to review its historical asbestos claim and resolution activity (including asbestos-related defense and processing costs) and determine the appropriateness of updating its December 2016 study. In response to that request, Ankura reviewed and analyzed data through September 30, 2018. The resulting study, completed by Ankura in December 2018, provided estimates for the undiscounted cost of disposing of pending and future claims against Union Carbide and Amchem, including future defense and processing costs, through the terminal year of 2049. Based on the study completed in December 2018 by Ankura, and Union Carbide's own review, it was determined that no adjustment to the accrual was required. At December 31, 2018, Union Carbide's asbestos-related liability for pending and future claims and defense and processing costs was $1,260 million, and approximately 16 percent of the recorded liability related to pending claims and approximately 84 percent related to future claims.

Summary
The Company’sCompany's management believes the amounts recorded by Union Carbide for the asbestos-related liability (including defense and processing costs) reflect reasonable and probable estimates of the liability based upon current, known facts. However, future events, such as the number of new claims to be filed and/or received each year, and the average cost of defending and disposing of each such claim, as well as the numerous uncertainties surrounding asbestos litigation in the United States over a significant period of time, could cause the actual costs for Union Carbide to be higher or lower than those projected or those recorded. Any such events could result in an increase or decrease in the recorded liability.

Because of the uncertainties described above, Union Carbide cannot estimate the full range of the cost of resolving pending and future asbestos-related claims facing Union Carbide and Amchem. As a result, it is reasonably possible that an additional cost of

disposing of Union Carbide's asbestos-related claims, including future defense and processing costs, could have a material impact on the Company's results of operations and cash flows for a particular period and on the consolidated financial position.

Urethane Matters
Class Action Lawsuit
On February 16, 2006, the Company, among others, received a subpoena from the DOJ as part of a previously announced antitrust investigation of manufacturers of polyurethane chemicals, including methylene diphenyl diisocyanate, toluene diisocyanate, polyether polyols and system house products. The Company cooperated with the DOJ and, following an extensive investigation, on December 10, 2007, the Company received notice from the DOJ that it had closed its investigation of potential antitrust violations involving these products without indictments or pleas.

In 2005, the Company, among others, was named as a defendant in multiple civil class action lawsuits alleging a conspiracy to fix the price of various urethane chemical products, namely the products that were the subject of the above described DOJ antitrust investigation. On July 29, 2008, a Kansas City federal district court (the "district court") certified a class of purchasers of the products for the six-year period from 1999 through 2004 ("plaintiff class"). In January 2013, the class action lawsuit went to trial with the Company as the sole remaining defendant, the other defendants having previously settled. On February 20, 2013, the federal jury returned a damages verdict of approximately $400 million against the Company, which ultimately was trebled under applicable antitrust laws, less offsets from other settling defendants, resulting in a judgment entered in July 2013 in the amount of $1.06 billion. The Company appealed this judgment to the U.S. Tenth Circuit Court of Appeals ("Court of Appeals"), and on September 29, 2014, the Court of Appeals issued an opinion affirming the district court judgment.

On March 9, 2015, the Company filed a petition for writ of certiorari ("Writ Petition") with the United States Supreme Court, seeking judicial review and requesting that it correct fundamental errors in the Court of Appeals decision. In the first quarter of 2016, the Company changed its risk assessment on this matter as a result of growing political uncertainties due to events within the Supreme Court, including Justice Scalia's death, and the increased likelihood for unfavorable outcomes for businesses involved in class action lawsuits. On February 26, 2016, the Company announced a proposed settlement under which the Company would pay the plaintiff class $835 million, which included damages, class attorney fees and post-judgment interest. On May 11, 2016, the Company moved the $835 million settlement amount into an escrow account. On July 29, 2016, the U.S. District Court for the District of Kansas granted final approval of the settlement and the funds were released from escrow on August 30, 2016.settlement. The settlement resolvesresolved the $1.06 billion judgment and any subsequent claim for attorneys' fees, costs and post-judgment interest against the Company. As a result, in the first quarter of 2016, the Company recorded a loss of $835 million, included in "Sundry income (expense) - net" in the consolidated statements of income. The Company continues to believe that it was not part of any conspiracy and the judgment was fundamentally flawed as a matter of class action law. The case is now concluded.

Opt-Out Cases
Shortly after the July 2008 class certification ruling, a series of "opt-out" cases were filed by a number of large volume purchasers who elected not to be class members in the district court case. These opt-out cases were substantively identical to the class action lawsuit, but expanded the period of time to include 1994 through 1998. A consolidated jury trial of the opt-out cases began on March 8, 2016. Prior to a jury verdict, on April 5, 2016, the Company entered into a binding settlement for the opt-out cases under which the Company would pay the named plaintiffs $400 million, inclusive of damages and attorney fees. Payment of this settlement occurred on May 4, 2016. The Company changed its risk assessment on this matter as a result of the class settlement and the uncertainty of a jury trial outcome along with the automatic trebling of an adverse verdict. As a result, the Company recorded a loss of $400 million in the first quarter of 2016, included in "Sundry income (expense) - net" in the consolidated statements of income. As with the class action case, the Company continues to deny allegations of price fixing and maintains that it was not part of any conspiracy. The case is now concluded.

Bayer CropScience v. Dow AgroSciences ICC Arbitration
On August 13, 2012, Bayer CropScience AG and Bayer CropScience NV (together, “Bayer”) filed a request for arbitration with the International Chamber of Commerce ("ICC") International Court of Arbitration against Dow AgroSciences LLC, a wholly owned subsidiary of the Company, and other subsidiaries of the Company (collectively, “DAS”) under a 1992 license agreement executed by predecessors of the parties (the “License Agreement”). In its request for arbitration, Bayer alleged that (i) DAS breached the License Agreement, (ii) the License Agreement was properly terminated with no ongoing rights to DAS, (iii) DAS has infringed and continues to infringe its patent rights related to the use of the pat gene in certain soybean and cotton seed products, and (iv) Bayer iswas entitled to monetary damages and injunctive relief. DAS denied that it breached the License Agreement and asserted that the License Agreement remained in effect because it was not properly terminated. DAS also asserted that all of Bayer’s patents at issue are invalid and/or not infringed, and, therefore, for these reasons (and others), a license was not required. During the pendency of the arbitration proceeding, DAS filed six re-examination petitions with the United States Patent & Trademark Office (“USPTO”) against the Bayer patents, asserting that each patent is invalid based on the doctrine against double-patenting and/or prior art. The USPTO granted all six petitions, and, on February 26, 2015, the USPTO issued an office action rejecting the

81

Table of Contents


patentability of the sole Bayer patent claim in the only asserted Bayer patent that has not expired and that forms the basis for the vast majority of the damages in the arbitral award discussed below.

A three-member arbitration tribunal presided over the arbitration proceeding (the “tribunal”). In a decision dated October 9, 2015, the tribunal determined that (i) DAS breached the License Agreement, (ii) Bayer properly terminated the License Agreement, (iii) all of the patents remaining in the proceeding are valid and infringed, and (iv) that Bayer is entitled to monetary damages in the amount of $455 million inclusive of pre-judgment interest and costs (the “arbitral award”). One of the arbitrators, however, issued a partial dissent finding that all of the patents are invalid based on the double-patenting doctrine. The tribunal also denied Bayer’s request for injunctive relief.

On October 16, 2015, Bayer filed a motion in U.S. District Court for the Eastern District of Virginia ("Federal District Court") seeking to confirm the arbitral award. DAS opposed the motion and filed separate motions to vacate the award, or in the alternative, to stay enforcement of the award until the USPTO issued final office actions with respect to the re-examination proceedings. On January 15, 2016, the Federal District Court denied DAS's motions and confirmed the award. DAS appealed the Federal District Court's decision. On March 1, 2017, the U.S. Court of Appeals for the Federal Circuit ("Federal Circuit") affirmed the arbitral award. As a result of this action, in the first quarter of 2017, the Company recorded a loss of $469 million, inclusive of the arbitral award and post-judgment interest, which was included in "Sundry income (expense) - net" in the consolidated statements of income. On May 19, 2017, the Federal Circuit issued a mandate denying DAS's request to stay the arbitral award pending judicial review by the United States Supreme Court. On May 26, 2017, the Company paid the $469 million arbitral award to Bayer as a result of that decision. On September 11, 2017, DAS filed a petition for writ of certiorari with the United States Supreme Court to review the case, but the Court denied DAS’s petition.

The litigation is now concluded with no risk of further liability. The Company continues to believe that the arbitral award is fundamentally flawed because, among other things, it allowed for the enforcement of invalid patents. The arbitral award and subsequent related judicial decisions will not impact DAS’s commercialization of its soybean and cotton seed products, including those containing the ENLIST™ technologies.

Rocky Flats Matter
The Company and Rockwell International Corporation ("Rockwell") (collectively, the "defendants") were defendants in a class action lawsuit filed in 1990 on behalf of property owners ("plaintiffs") in Rocky Flats, Colorado, who asserted claims for nuisance and trespass based on alleged property damage caused by plutonium releases from a nuclear weapons facility owned by the U.S. Department of Energy ("DOE") (the "facility"). Dow and Rockwell were both DOE contractors that operated the facility - Dow from 1952 to 1975 and Rockwell from 1975 to 1989. The facility was permanently shut down in 1989.

In 1993, the United States District Court for the District of Colorado ("District Court") certified the class of property owners. The plaintiffs tried their case as a public liability action under the Price Anderson Act ("PAA"). In 2005, the jury returned a damages verdict of $926 million. Dow and Rockwell appealed the jury award to the U.S. Tenth Circuit Court of Appeals ("Court of Appeals") which concluded the PAA had its own injury requirements, on which the jury had not been instructed, and also vacated the District Court's class certification ruling, reversed and remanded the case, and vacated the District Court's judgment. The plaintiffs argued on remand to the District Court that they were entitled to reinstate the judgment as a state law nuisance claim, independent of the PAA. The District Court rejected that argument and entered judgment in favor of the defendants. The plaintiffs appealed to the Court of Appeals, which reversed the District Court's ruling, holding that the PAA did not preempt the plaintiffs' nuisance claim under Colorado law and that the plaintiffs could seek reinstatement of the prior nuisance verdict under Colorado law.

Dow and Rockwell continued to litigate this matter in the District Court and in the United States Supreme Court following the appellate court decision. On May 18, 2016, Dow, Rockwell and the plaintiffs entered into a settlement agreement for $375 million, of which $131 million was to be paid by Dow. The DOE authorized the settlement pursuant to the PAA and the nuclear hazards indemnity provisions contained in Dow's and Rockwell's contracts. The District Court granted preliminary approval to the class settlement on August 5, 2016. On April 28, 2017, the District Court conducted a fairness hearing and granted final judgment approving the class settlement and dismissed class claims against the defendants ("final judgment order").

On December 13, 2016, the United States Civil Board of Contract Appeals unanimously ordered the United States government to pay the amounts stipulated in the settlement agreement. On January 17, 2017, the Company received a full indemnity payment of $131 million from the United States government for Dow's share of the class settlement. On January 26, 2017, the Company placed $130 million in an escrow account for the settlement payment owed to the plaintiffs. The funds were subsequently released from escrow as a result of the final judgment order. At December 31, 2017, there are no outstanding balances in the consolidated balance sheets related to this matter ($131 million included in "Accounts and notes receivable - Other" and $130 million included in "Accrued and other current liabilities" at December 31, 2016). The litigation is now concluded.

Dow CorningSilicones Chapter 11 Related Matters
Introduction
In 1995, Dow Corning,Silicones, then a 50:50 joint venture between Dow and Corning, voluntarily filed for protection under Chapter 11 of the U.S. Bankruptcy Code in order to resolve Dow Corning’sSilicones’ breast implant liabilities and related matters (the “Chapter 11 Proceeding”). Dow CorningSilicones emerged from the Chapter 11 Proceeding on June 1, 2004 (the “Effective Date”) and is implementing the Joint Plan of Reorganization (the “Plan”). The Plan provides funding for the resolution of breast implant and other product liability litigation covered by the Chapter 11 Proceeding and provides a process for the satisfaction of commercial creditor claims in the Chapter 11 Proceeding. As of June 1, 2016, Dow CorningSilicones is a wholly owned subsidiary of Dow.

Breast Implant and Other Product Liability Claims
Under the Plan, a product liability settlement program administered by an independent claims office (the “Settlement Facility”) was created to resolve breast implant and other product liability claims. Product liability claimants rejecting the settlement program in favor of pursuing litigation must bring suit against a litigation facility (the “Litigation Facility”). Under the Plan, total payments committed by Dow CorningSilicones to resolving product liability claims are capped at a maximum $2,350 million net present value (“NPV”) determined as of the Effective Date using a discount rate of seven percent (approximately $3,746$3,876 million undiscounted at December 31, 2017)2018). Of this amount, no more than $400 million NPV determined as of the Effective Date can be used to fund the Litigation Facility.

Dow CorningSilicones has an obligation to fund the Settlement Facility and the Litigation Facility over a 16-year period, commencing at the Effective Date. At
December 31, 2017,2018, Dow CorningSilicones and its insurers have made life-to-date payments of $1,762 million to the Settlement Facility and the Settlement Facility reported an unexpended balance of $135$118 million.

On June 1, 2016, as part of the ownership restructure of Dow CorningSilicones and in accordance with ASC 450 "Accounting for Contingencies," the Company recorded a liability of $290 million for breast implant and other product liability claims (“Implant Liability”), which reflected the estimated impact of the settlement of future claims primarily based on reported claim filing levels in the Revised Settlement Program (the “RSP”) and on the resolution of almost all cases pending against the Litigation Facility. The RSP was a program sponsored by certain other breast implant manufacturers in the context of multi-district, coordinated federal breast implant cases and was open from 1995 through 2010. The RSP was also a revised successor to an earlier settlement plan involving Dow CorningSilicones (prior to its bankruptcy filing). While Dow CorningSilicones withdrew from the RSP, many of the benefit categories and payment levels in Dow Corning’sSilicones settlement program were drawn from the RSP. Based on the comparability in design and actual claim experience of both plans, management concluded that claim information from the RSP provides a reasonable basis to estimate future claim filing levels for the Settlement Facility.

In the fourth quarter of 2016, with the assistance of a third party consultant ("consultant"), Dow CorningSilicones updated its estimate of its Implant Liability to $263 million, primarily reflecting a decrease in Class 7 costs (claimants who have breast implants made by certain other manufacturers using primarily Dow CorningSilicones silicone gel), a decrease resulting from the passage of time, decreased

claim filing activity and administrative costs compared with the previous estimate, and an increase in investment income resulting from insurance proceeds. Based on the consultant's updated estimate and Dow Corning'sSilicones own review of claim filing activity, Dow CorningSilicones determined that an adjustment to the Implant Liability was required. Accordingly, Dow CorningSilicones decreased its Implant Liability in the fourth quarter of 2016 by $27 million, which was included in "Sundry income (expense) - net" in the consolidated statements of income. At December 31, 2018, the Implant Liability was $263 million, of which $111 million was included in “Accrued and other current liabilities” and $152 million was included in "Other noncurrent obligations" in the consolidated balance sheets. At December 31, 2017, the Implant Liability was $263 million, ($263 million at December 31, 2016) andwhich was included in "Other noncurrent obligations" in the consolidated balance sheets.

Dow CorningSilicones is not aware of circumstances that would change the factors used in estimating the Implant Liability and believes the recorded liability reflects the best estimate of the remaining funding obligations under the Plan; however, the estimate relies upon a number of significant assumptions, including: future claim filing levels in the Settlement Facility will be similar to those in the revised settlement program, which management uses to estimate future claim filing levels for the Settlement Facility; future acceptance rates, disease mix, and payment values will be materially consistent with historical experience; no material negative outcomes in future controversies or disputes over Plan interpretation will occur; and the Plan will not be modified. If actual outcomes related to any of these assumptions prove to be materially different, the future liability to fund the Plan may be materially different than the amount estimated. If Dow CorningSilicones was ultimately required to fund the full liability up to the maximum capped value, the liability would be $1,985$2,114 million at December 31, 2017.2018.

Commercial Creditor Issues
The Plan provides that each of Dow Corning’sSilicones commercial creditors (the “Commercial Creditors”) would receive in cash the sum of (a) an amount equal to the principal amount of their claims and (b) interest on such claims. The actual amount of interest that will ultimately be paid to these Commercial Creditors is uncertain due to pending litigation between Dow CorningSilicones and the Commercial Creditors regarding the appropriate interest rates to be applied to outstanding obligations from the 1995 bankruptcy filing date through the Effective Date, as well as the presence of any recoverable fees, costs, and expenses. Upon the Plan becoming

83

Table of Contents


effective, Dow CorningSilicones paid approximately $1,500 million to the Commercial Creditors, representing principal and an amount of interest that Dow CorningSilicones considers undisputed.

In 2006, the U.S. Court of Appeals for the Sixth Circuit concluded that there is a general presumption that contractually specified default interest should be paid by a solvent debtor to unsecured creditors (the “Interest Rate Presumption”) and permitting Dow Corning’sthe Commercial Creditors to recover fees, costs, and expenses where allowed by relevant loan agreements. The matter was remanded to the U.S. District Court for the Eastern District of Michigan ("District Court") for further proceedings, including rulings on the facts surrounding specific claims and consideration of any equitable factors that would preclude the application of the Interest Rate Presumption. On May 10, 2017, the District Court entered a stipulated order resolving pending discovery motions and established a discovery schedule for the Commercial Creditors matter. As a result, Dow CorningSilicones and its third party consultants conducted further analysis of the Commercial Creditors claims and defenses. This analysis indicated the estimated remaining liability to the Commercial Creditors to be within a range of $77 million to $260 million. No single amount within the range appears to be a better estimate than any other amount within the range. Therefore, Dow Corning Siliconesrecorded the minimum liability within the range, which resulted in a decrease to the Commercial Creditor liability of $33 million in the second quarter of 2017, which was included in "Sundry income (expense) - net" in the consolidated statements of income. At December 31, 2017,2018, the liability related to Dow Corning’sSilicones' potential obligation to pay additional interest to itsthe Commercial Creditors in the Chapter 11 Proceeding was $78$82 million ($10878 million at December 31, 2016)2017) and included in "Accrued and other current liabilities" in the consolidated balance sheets. The actual amount of interest that will be paid to these creditors is uncertain and will ultimately be resolved through continued proceedings in the District Court.

Indemnifications
In connection with the June 1, 2016 ownership restructure of Dow Corning,Silicones, the Company is indemnified by Corning for 50 percent of future losses associated with certain pre-closing liabilities, including the Implant Liability and Commercial Creditors matters described above, subject to certain conditions and limits. The maximum amount of indemnified losses which may be recovered are subject to a cap that declines over time. Indemnified losses are capped at (1) $1.5 billion until May 31, 2018, (2) $1 billion between May 31, 2018 and May 31, 2023, and (3)(2) no recoveries are permitted after May 31, 2023. No indemnification assets were recorded at December 31, 20172018 or 2016.2017.

Summary
The amounts recorded by Dow CorningSilicones for the Chapter 11 related matters described above were based upon current, known facts, which management believes reflect reasonable and probable estimates of the liability. However, future events could cause the actual costs for Dow CorningSilicones to be higher or lower than those projected or those recorded. Any such events could result in an increase or decrease in the recorded liability.

Other Litigation Matters
In addition to the specific matters described above, the Company is party to a number of other claims and lawsuits arising out of the normal course of business with respect to product liability, patent infringement, employment matters, governmental tax and regulation disputes, contract and commercial litigation, and other actions. Certain of these actions purport to be class actions and seek damages in very large amounts. All such claims are being contested. Dow has an active risk management program consisting of numerous insurance policies secured from many carriers at various times. These policies may provide coverage that could be utilized to minimize the financial impact, if any, of certain contingencies described above. 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.

Gain Contingency - Dow v. Nova Chemicals Corporation Patent Infringement Matter
On December 9, 2010, Dow filed suit in the Federal Court in Ontario, Canada ("Federal Court") alleging that Nova Chemicals Corporation ("Nova") was infringing the Company's Canadian polyethylene patent 2,106,705 (the "'705 Patent"). Nova counterclaimed on the grounds of invalidity and non-infringement. In accordance with Canadian practice, the suit was bifurcated into a merits phase, followed by a damages phase. Following trial in the merits phase, in May 2014 the Federal Court ruled that the Company's '705 Patent was valid and infringed by Nova. Nova appealed to the Canadian Federal Court of Appeal, which affirmed the Federal Court decision in August 2016. Nova then sought leave to appeal its loss to the Supreme Court of Canada, which dismissed Nova’s petition in April 2017. As a result, Nova has exhausted all appeal rights on the merits, and it is undisputed that Nova owes Dow the profits it earned from its infringing sales as determined in the trial for the damages phase.

On April 19, 2017, the Federal Court issued a Public Judgment in the damages phase, which detailed its conclusions on how to calculate the profits to be awarded to Dow. Dow and Nova submitted their respective calculations of the damages to the Federal Court in May 2017. On June 29, 2017, the Federal Court issued a Confidential Supplemental Judgment, concluding that Nova must pay $645 million Canadian dollars (equivalent to $495 million U.S. dollars) to Dow, plus pre- and post-judgment interest, for which Dow received payment of $501 million from Nova on July 6, 2017. Although Nova is appealing portions of the damages

84

Table of Contents


judgment, certain portions of it are indisputable and will be owed to Dow regardless of the outcome of any further appeals by Nova. As a result of these actions and in accordance with ASC 450-30 "Gain Contingencies," the Company recorded a $160 million pretax gain in the second quarter of 2017 of which $137 million was included in "Sundry income (expense) - net" and $23 million was included in "Selling, general and administrative expenses" in the consolidated statements of income. At December 31, 2017,2018, the Company had $341 million ($341 million at December 31, 2017) included in "Other noncurrent obligations" related to the disputed portion of the damages judgment. Dow is confident of its chances of defending the entire judgment on appeal, particularly the trial court's determinations on important factual issues, which will be accorded deferential review on appeal.

Purchase Commitments
The Company has outstanding purchase commitments and various commitments for take-or-pay or throughput agreements. The Company was not aware of any purchase commitments that were negotiated as part of a financing arrangement for the facilities that will provide the contracted goods or services or for the costs related to those goods or services at December 31, 20172018 and 2016.2017.

Guarantees
Guarantees arise during the ordinary course of business from relationships with customers and nonconsolidated affiliates when the Company undertakes an obligation to guarantee the performance of others (via delivery of cash or other assets) if specified triggering events occur. With guarantees, such as commercial or financial contracts, non-performance by the guaranteed party triggers the obligation of the Company to make payments to the beneficiary of the guarantee. The majority of the Company’s guarantees relate to debt of nonconsolidated affiliates, which have expiration dates ranging from less than one year to sixless than

83

Table of Contents


five years, and trade financing transactions in Latin America, which typically expire within one year of inception. The Company’s current expectation is that future payment or performance related to the non-performance of others is considered remote.

The Company has entered into guarantee agreements (“Guarantees”) related to project financing for Sadara.Sadara, a nonconsolidated affiliate. The total of an Islamic bond and additional project financing (collectively “Total Project Financing”) obtained by Sadara is approximately $12.5 billion. Sadara had $12.4$11.7 billion of Total Project Financing outstanding at December 31, 20172018 ($12.4 billion at December 31, 2016)2017). The Company's guarantee of the Total Project Financing is in proportion to the Company's 35 percent ownership interest in Sadara, or up to approximately $4.4$4.2 billion when the project financing is fully drawn. TheSadara successfully completed an extensive operational testing program in December 2018, however, the Guarantees will be released upon completion of construction of the Sadara complex and satisfactory fulfillment of certain otherproject completion conditions, including passage of an extensive operational testing program, which is currently anticipatedexpected by the endmiddle of 20182019, and must occur no later than December 2020.

Residual Value Guarantees
The Company provides guarantees related to leased assets specifying the residual value that will be available to the lessor at lease termination through sale of the assets to the lessee or third parties.

Operating Leases
The Company routinely leases premises for use as sales and administrative offices, warehouses and tanks for product storage, motor vehicles, railcars, computers, office machines and equipment. In addition, the Company leases aircraft in the United States. The terms for these leased assets vary depending on the lease agreement. Some leases contain renewal provisions, purchase options and escalation clauses.

Asset Retirement Obligations
Dow has 178164 manufacturing sites in 35 countries. Most of these sites contain numerous individual manufacturing operations, particularly at the Company’s larger sites. Asset retirement obligations are recorded as incurred and reasonably estimable, including obligations for which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the Company. The retirement of assets may involve such efforts as remediation and treatment of asbestos, contractually required demolition, and other related activities, depending on the nature and location of the assets; and retirement obligations are typically realized only upon demolition of those facilities. In identifying asset retirement obligations, the Company considers identification of legally enforceable obligations, changes in existing law, estimates of potential settlement dates and the calculation of an appropriate discount rate to be used in calculating the fair value of the obligations. Dow has a well-established global process to identify, approve and track the demolition of retired or to-be-retired facilities; and no assets are retired from service until this process has been followed. Dow typically forecasts demolition projects based on the usefulness of the assets; environmental, health and safety concerns; and other similar considerations. Under this process, as demolition projects are identified and approved, reasonable estimates are determined for the time frames during which any related asset retirement obligations are expected to be settled. For those assets where a range of potential settlement dates may be reasonably estimated, obligations are recorded. Dow routinely reviews all changes to items under consideration for demolition to determine if an adjustment to the value of the asset retirement obligation is required.

The Company has recognized asset retirement obligations for the following activities: demolition and remediation activities at manufacturing sites primarily in the United States, Canada, Brazil, Argentina, Columbia, China, Japan, United Arab Emirates and Europe; and capping activities at landfill sites in the United States, Canada Brazil and Italy.Brazil. The Company has also recognized conditional asset retirement obligations related to asbestos encapsulation as a result of planned demolition and remediation activities at manufacturing and administrative sites primarily in the United States, Canada, Argentina, Columbia, China and Europe. The aggregate carrying amount of conditional asset retirement obligations recognized by the Company (included in the asset retirement obligations balance shown below) was $20$24 million at December 31, 20172018 ($3120 million at December 31, 2016)2017).

The following table shows changes in the aggregate carrying amount of the Company’s asset retirement obligations for the years ended December 31, 20172018 and 2016:2017:

The discount rate used to calculate the Company’s asset retirement obligations at December 31, 2017,2018, was 2.043.54 percent (1.87(2.04 percent at December 31, 2016)2017). These obligations are included in the consolidated balance sheets as "Accrued and other current liabilities" and "Other noncurrent obligations."

Table of Contents


The Company has not recognized conditional asset retirement obligations for which a fair value cannot be reasonably estimated in its consolidated financial statements. Assets that have not been submitted/reviewed for potential demolition activities are considered to have continued usefulness and are generally still operating normally. Therefore, without a plan to demolish the assets or the expectation of a plan, such as shortening the useful life of assets for depreciation purposes in accordance with the accounting guidance related to property, plant and equipment, the Company is unable to reasonably forecast a time frame to use for present value calculations. As such, the Company has not recognized obligations for individual plants/buildings at its manufacturing sites where estimates of potential settlement dates cannot be reasonably made. In addition, the Company has not recognized conditional asset retirement obligations for the capping of its approximately 4237 underground storage wells and 141128 underground brine mining and other wells at Dow-owned sites when there are no plans or expectations of plans to exit the sites. It is the opinion of the Company’s management that the possibility is remote that such conditional asset retirement obligations, when estimable, will have a material impact on the Company’s consolidated financial statements based on current costs.


NOTE 17 – STOCKHOLDERS’ EQUITY
Merger with DuPont
Effective with the Merger, each share of Dow Common Stock (excluding any shares of Dow Common Stock that were held in treasury, which were automatically canceled and retired for no consideration) was converted into the right to receive one fully paid and non-assessable share of DowDuPont Common Stock. As a result, in the third quarter of 2017, the Company recorded a reduction in "Treasury stock" of $935 million, a reduction in "Common stock" of $3,107 million and an increase in "Additional paid in capital" of $2,172 million in the consolidated balance sheets. The Company has 100 shares of common stock issued and outstanding, par value $0.01 per share, owned solely by its parent, DowDuPont. See Note 3 for additional information.

Cumulative Convertible Perpetual Preferred Stock, Series A
Equity securities in the form of Cumulative Convertible Perpetual Preferred Stock, Series A (“preferred series A”) were issued on April 1, 2009 to Berkshire Hathaway Inc. in the amount of $3 billion (3 million shares) and the Kuwait Investment Authority in the amount of $1 billion (1 million shares). Shareholders of preferred series A could convert all or any portion of their shares, at their option, at any time, into shares of the Company’s common stock at an initial conversion ratio of 24.2010 shares of common stock for each share of preferred series A. On or after the fifth anniversary of the issuance date, if the common stock price exceeded $53.72 per share for any 20 trading days in a consecutive 30-day window, the Company had the option, at any time, in whole or in part, to convert preferred series A into common stock at the then applicable conversion rate.

Table of Contents


On December 15, 2016, the trading price of Dow's common stock closed at $58.35, marking the 20th trading day in the previous 30 trading days that the common stock closed above $53.72, triggering the right of the Company to exercise its conversion right. On December 16, 2016, the Company sent a Notice of Conversion at the Option of the Company (the "Notice") to all holders of its preferred series A. Pursuant to the Notice, on December 30, 2016 (the "Conversion Date") all 4 million outstanding shares of preferred series A (with a carrying value of $4,000 million) were converted into shares of common stock at a conversion ratio of 24.2010 shares of common stock for each share of preferred series A, resulting in the issuance of 96.8 million shares of common stock from treasury stock. The treasury stock issued was carried at an aggregate historical cost of $4,695 million, resulting in a reduction to "Additional paid-in capital" in the consolidated balance sheets of $695 million. From and after the Conversion Date, no shares of the preferred series A are issued or outstanding and all rights of the holders of the preferred series A have terminated. On January 6, 2017, the Company filed an amendment to the Company’s Restated Certificate of Incorporation by way of a certificate of elimination (the “Certificate of Elimination”) with the Secretary of State of the State of Delaware which had the effect of: (a) eliminating the previously designated 4 million shares of the preferred series A, none of which were outstanding at the time of the filing; (b) upon such elimination, causing such preferred series A to resume the status of authorized and unissued shares of preferred stock, par value $1.00 per share, of the Company, without designation as to series; and (c) eliminating from the Company’s Restated Certificate of Incorporation all references to, and all matters set forth in, the certificates of designations for the preferred series A.
 
The Company paid cumulative dividends on preferred series A at a rate of 8.5 percent per annum, or $85 million per quarter. The final dividend for the preferred series A was declared on December 15, 2016 and payable on the earlier of the Conversion Date (if applicable) or January 3, 2017, to shareholders of record at December 15, 2016. The dividend was paid in full on the Conversion Date.

Common Stock
Prior to the Merger, the Company issued common stock shares out of treasury stock or as new common stock shares for purchases under the Employee Stock Purchase Plan, for options exercised and for the release of deferred, performance deferred and restricted stock. The number of new common stock shares issued to employees and non-employee directors prior to the Merger was zero in

87

Table of Contents


2017 (zero in 2016 and approximately 32,000 in 2015)2016). See Note 20 for additional information on changes to Dow equity awards in connection with the Merger.

Retained Earnings
There are no significant restrictions limiting the Company’s ability to pay dividends. Prior to the Merger, the Company declared dividends of $1.38 per share in 2017 ($1.84 per share in 2016 and $1.72 per share in 2015)2016). Effective with the Merger, Dow no longer has publicly traded common stock. Dow's common shares are owned solely by its parent company, DowDuPont. As a result, the Company’s Board of Directors determines whether or not there will be a dividend distribution to DowDuPont. See Note 24 for additional information.

Undistributed earnings of nonconsolidated affiliates included in retained earnings were $1,760 million at December 31, 2018 and $1,731 million at December 31, 2017 and $1,196 million at December 31, 2016.2017.

Employee Stock Ownership Plan
The Dow Employee Stock Ownership Plan (the “ESOP”) is an integral part of The Dow Chemical Company Employees’ Savings Plan (the “Plan”). A significant majority of full-time employees in the United States are eligible to participate in the Plan. Dow uses the ESOP to provide the Company’s matching contribution in the form of stock to Plan participants. Prior to the Merger, contributions were in the form of Dow Common Stock. Effective with the Merger, shares of Dow stock held by the ESOP were converted into shares of DowDuPont Common Stock at a ratio of 1:1.

In connection with the acquisition of Rohm and Haas on April 1, 2009, the Rohm and Haas Employee Stock Ownership Plan (the "Rohm and Haas ESOP") was merged into the Plan, and the Company assumed the $78 million balance of debt at 9.8 percent interest with final maturity in 2020 that was used to finance share purchases by the Rohm and Haas ESOP in 1990. The outstanding balance of the debt was $10 million at December 31, 2018 and $17 million at December 31, 2017 and $24 million at December 31, 2016.2017.

Dividends on unallocated shares held by the ESOP are used by the ESOP to make debt service payments and to purchase additional shares if dividends exceed the debt service payments. Dividends on allocated shares are used by the ESOP to make debt service payments to the extent needed; otherwise, they are paid to the Plan participants. Shares are released for allocation to participants based on the ratio of the current year’s debt service to the sum of the principal and interest payments over the life of the loan. The shares are allocated to Plan participants in accordance with the terms of the Plan.

Compensation expense for allocated shares is recorded at the fair value of the shares on the date of allocation. Compensation expense for ESOP shares was $175 million in 2018, $248 million in 2017 and $192 million in 2016 and $174 million in 2015.2016. At December 31, 2017, 15.52018, 15.3 million shares out of a total 25.621.8 million shares held by the ESOP had been allocated to participants’ accounts; 2.21.5 million shares were released but unallocated; and 7.95.0 million shares, at a fair value of $566$267 million, were considered unearned.

Treasury Stock
In 2013, the Board approved a share buy-back program. As a result of subsequent authorizations approved by the Board, the total authorized amount of the share repurchase program was $9.5 billion. Effective with the Merger, the share repurchase program was canceled. Over the duration of the program, a total of $8.1 billion was spent on the repurchase of Dow Common Stock.

The Company historically issued shares for purchases under the Employee Stock Purchase Plan, for options exercised as well as for the release of deferred, performance deferred and restricted stock out of treasury stock or as new common stock shares. The number of treasury shares issued to employees and non-employee directors under the Company’s stock-based compensation programs are summarized in the following table.

NOTE 19 – PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS
Dow and DuPont did not merge their defined benefit pension plans and other postretirement benefit plans as a result of the Merger. See Note 3 for additional information on the Merger.

Defined Benefit Pension Plans
The Company has both funded and unfunded defined benefit pension plans that cover employees in the United States and a number of other countries. The U.S. qualified plan covering the parent company is the largest plan. Benefits for employees hired before January 1, 2008, are based on length of service and the employee’s three highest consecutive years of compensation. Employees hired after January 1, 2008, earn benefits that are based on a set percentage of annual pay, plus interest.

The Company's funding policy is to contribute to the plans when pension laws and/or economics either require or encourage funding. In 2017,2018, the Company contributed $1,676$1,656 million to its pension plans, includingwhich included a $1,100 million discretionary contribution to its principal U.S. pension plan in the third quarter of 2018. Total contributions in 2018 also included contributions to fund benefit payments for itsthe Company's non-qualified pension plans. The Company expects to contribute approximately $500$240 million to its pension plans in 2018.2019.

The provisions of a U.S. non-qualified pension plan require the payment of plan obligations to certain participants upon a change in control of the Company, which occurred at the time of the Merger. Certain participants could elect to receive a lump-sum payment or direct the Company to purchase an annuity on their behalf using the after-tax proceeds of the lump sum. In the fourth quarter of 2017, the Company paid $940 million to plan participants and $230 million to an insurance company for the purchase of annuities, which were included in "Pension contributions" in the consolidated statements of cash flows. The Company also paid $205 million for income and payroll taxes for participants electing the annuity option, of which $201 million was included in "Cost of sales" and $4 million was included in "Selling, general and administrative expenses" in the consolidated statements of income. The Company recorded a settlement charge of $687 million associated with the payout in the fourth quarter of 2017, which was included in "Cost of sales""Sundry income (expense) - net" in the consolidated statements of income.

Other Postretirement Benefit Plans
The Company provides certain health care and life insurance benefits to retired employees and survivors. The Company’s plans outside of the United States are 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. The Company and the retiree share the cost of these benefits, with the Company portion increasing as the retiree has increased years of credited service, although there is a cap on the Company portion. The Company has the ability to change these benefits at any time. Employees hired after January 1, 2008, are not covered under the plans.

The Company funds most of the cost of these health care and life insurance benefits as incurred. In 2017,2018, Dow did not make any contributions to its other postretirement benefit plan trusts. The trusts did not hold assets at December 31, 2017.2018. The Company does not expect to contribute assets to its other postretirement benefit plan trusts in 2018.2019.

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. The expected long-term rate of return for each asset class is then weighted based on the strategic asset allocation approved by the governing body for each plan. The Company’s historical experience with the pension fund asset performance is also considered.

Effective January 1, 2016, theThe Company adopteduses the spot rate approach to determine the discount rate utilized to measure the service cost and interest cost components of net periodic pension and other postretirement benefit costs for the U.S. and other selected countries. Under the spot rate approach, the Company calculates service costs and interest costs by applying individual spot rates from the Willis Towers Watson RATE:Link yield curve (based on high-quality corporate bond yields) for each selected country to the separate expected cash flow components of service cost and interest cost. Service cost and interest cost for all other plans are determined on the basis of the single equivalent discount rates derived in determining those plan obligations. The Company changed to the new method to provide a more precise measure of interest and service costs for certain plans by improving the correlation between projected benefit cash flows and the discrete spot yield curves. The Company accounted for this change as a change in accounting estimate and it was applied prospectively starting in 2016.

The discount rates utilized to measure the pension and other postretirement obligations of the U.S. qualified plans are based on the yield on high-quality corporate fixed income investments at the measurement date. Future expected actuarially determined cash flows for Dow’s U.S. plans are individually discounted at the spot rates under the Willis Towers Watson U.S. RATE:Link 60-90 corporate yield curve (based on 60th to 90th percentile high-quality corporate bond yields) to arrive at the plan’s obligations as of the measurement date.

The Company utilizes a modified version of the Society of Actuaries’ mortality tables released in 2014 and a modified version of the generational mortality improvement scale released in 20142018 for purposes of measuring the U.S. pension and other postretirement obligations, based on an evaluation of the mortality experience of the Company’s pension plans.

5.Updated to conform with the current year presentation.

A significant component of the overall decrease in the Company's benefit obligation for the year ended December 31, 2018 was due to the weighted-average change in discount rates, which increased from 3.17 percent at December 31, 2017 to 3.69 percent at December 31, 2018. A significant component of the overall increase in the Company's benefit obligation for the year ended December 31, 2017 was also due to the weighted-average change in discount rates, which decreased from 3.52 percent at December 31, 2016 to 3.17 percent at December 31, 2017.

Plan Assets
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 equitymarket securities and absolute return strategies. At December 31, 2018, plan assets totaled $22.5 billion and included no directly held common stock of DowDuPont. At December 31, 2017, plan assets totaled $23.4 billion and included no directly held common stock of DowDuPont. At December 31, 2016, plan assets totaled $21.2 billion and included no directly held common stock of Dow.

The Company's investment strategy for the plan assets is 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 is 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 are 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 use 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 include investments in large- and small-cap companies located in both developed and emerging markets around the world. Fixed income securities include 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 include investments in real estate, private equity limited partnerships and absolute return strategies. Other significant investment types include various insurance contracts;contracts and interest rate, equity, commodity and foreign exchange derivative investments and hedges.

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

The Northern Trust Collective Government Short Term Investment money market fund is utilized as the sweep vehicle for the U.S. plans, which from time to time can represent a significant investment. For one U.S. plan, approximately 35 percent of the liability is covered by a participating group annuity issued by Prudential Insurance Company.

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 or fund managers provide valuations of the investment on a monthly or quarterly basis. These valuations are reviewed for reasonableness based on applicable sector, benchmark and company performance. Adjustments to valuations are made where appropriate. Where available, audited financial statements are obtained and reviewed for the investments as support for the manager’s investment valuation. Some

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 adjusted forcompany performance. Adjustments to valuations are made where appropriate to arrive at an estimated earnings and investment activity.net asset value per share at the measurement date. These funds are not classified as Level 3 due to the significant unobservable inputs inherent inwithin the fair value measurement.hierarchy.

The assets are presented as "Investments measured at December 31, 2016 of assets from equity securities to alternative investments and $481 million at December 31, 2016 ($276 million at January 1, 2016) of assets from fixed income securities to alternative investments.net asset value."

Defined Contribution Plans
U.S. employees may participate in defined contribution plans (Employee Savings Plans or 401(k) plans) by contributing a portion of their compensation, which is partially matched by the Company. Defined contribution plans also cover 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, $367 million in 2017 and $283 million in 2016 and $235 million in 2015.2016.


NOTE 20 – STOCK-BASED COMPENSATION
The Company grants stock-based compensation to employees and non-employee directors in the form of stock incentive plans, which include stock options, restricted stock units ("RSUs") (formerly termed deferred stockstock) and restricted stock. The Company also provides stock-based compensation in the form of performance stock units ("PSUs") (formerly termed performance deferred stockstock) and the Employee Stock Purchase Plan (“ESPP”), which grants eligible employees the right to purchase shares of the Company's common stock at a discounted price.

In connection with the Merger, on August 31, 2017 ("Conversion Date") all outstanding Dow stock options and deferred stockRSU awards were converted into stock options and deferred stockRSU awards with respect to DowDuPont common stock. The stock options and deferred stockRSU awards have the same terms and conditions under the applicable plans and award agreements prior to the Merger. All outstanding and nonvested performance deferred stockPSU awards were converted into deferred stockRSU 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. Dow and DuPont did not merge their stock-based compensation plans as a result of the Merger. The Dow and DuPont stock-based compensation plans were assumed by DowDuPont and continue in place with the ability to grant and issue DowDuPont common stock.

The total stock-based compensation expense included in the consolidated statements of income was $224 million, $359 million and $261 million in 2018, 2017 and $352 million in 2017, 2016, and 2015, respectively. The income tax benefits related to stock-based compensation arrangements were $50 million, $133 million and $97 million in 2018, 2017 and $129 million in 2017, 2016, and 2015, respectively.

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 (specifically, performance deferred stock awards, which are granted(granted to executive employees subject to stock ownership requirements, that provide the recipient the option to elect to receive a cash payment equal to the value of the stock award on the date of delivery) 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.

Table of Contents


The Company historically 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 performance deferredPSU awards. Effective with the first quarter of 2018 grant, the Company began using the Black-Scholes option valuation model to estimate the fair value of stock awards.options. This valuation methodology was adopted as a result of the Merger to align valuation methodologies with DuPont and better align with industry practice. The Company 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:

The dividend yield assumption was equal to the dividend yield on the grant date, which reflected the most recent DowDuPont quarterly dividend payment of $0.46$0.38 per share in 20172018 ($0.46 per share in 2017 and 2016 and $0.42 per share in 2015)on Dow Common Stock). The expected volatility assumptions for the 2016 and 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 performance deferred stock2016 and 2017 PSU awards waswere 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 2016 and 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.

Stock Incentive Plan
The Company has historically granted equity awards under various plans (the "Prior Plans"). On February 9, 2012, the Board authorized The Dow Chemical Company 2012 Stock Incentive Plan (the "2012 Plan"), which was approved by stockholders at the Company's annual meeting on May 10, 2012 ("Original Effective Date") and became effective on that date. On February 13, 2014, the Board 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 the Company'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, the Company may grant options, deferred stock, performance deferred stock,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. Dow's stock-based compensation programs were assumed by DowDuPont and continue in place with the ability to grant and issue DowDuPont common stock. At December 31, 2017,2018, there were approximately 2919 million shares of DowDuPont common stock available for grant under the 2012 Plan.

Stock Options
The Company grants 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 the common stock on the grant date. Options vest from one to three years, and have a maximum term of 10 years.

Dow’s business operations give rise to market risk exposure due to changes in interestforeign exchange rates, foreign currency exchangeinterest rates, commodity prices and other market factors such as equity prices. To manage such risks effectively, the Company enters into hedging transactions, pursuant to established guidelines and policies whichthat enable it to mitigate the adverse effects of financial market risk. Derivatives used for this purpose are designated as cash flow, fair value or net foreign investment hedges per the accounting guidance related to derivatives and hedging activities, where appropriate. Accounting guidance requires companies to recognize all derivative instruments as either assets or liabilities at fair value. A secondary objective is to add value by creating additional nonspecific exposuresnon-specific exposure within established limits and policies; derivatives used for this purpose are not designated as hedges. The potential impact of creating such additional exposures is not material to the Company’s results. Accounting guidance requires companies to recognize all derivative instruments as either assets or liabilities at fair value.

The Company’s risk management program for interest rate, foreign currency and commodity risks is based on fundamental, mathematical and technical models that take into account the implicit cost of hedging. Risks created by derivative instruments and the mark-to-market valuations of positions are strictly monitored at all times, using value-at-risk and stress tests. Counterparty credit risk arising from these contracts is not significant because the Company minimizes counterparty concentration, deals primarily with major financial institutions of solid credit quality, and the majority of its hedging transactions mature in less than three months. In addition, the Company minimizes concentrations of credit risk through its global orientation by transacting with large, internationally diversified financial counterparties. It is the Company’s policy to not have credit risk-related contingent features in its derivative instruments. No significant concentration of counterparty credit risk existed at December 31, 2017.2018. The Company does not anticipate losses from credit risk, and the net cash requirements arising from counterparty risk associated with risk management activities are not expected to be material in 2018.2019.

The Company revises its strategies as market conditions dictate and management reviews its overall financial strategies and the impacts from using derivatives in its risk management program with the Company’s senior leadership who also reviews these strategies with the DowDuPont Board of Directors and/or relevant committees thereof.

Interest Rate Risk Management
The Company enters into variousmain objective of interest rate contracts withrisk management is to reduce the objective of loweringtotal funding costs or alteringcost to the Company and to alter the interest rate exposures relatedexposure to fixed and variable rate obligations. In these contracts,the desired risk profile. To achieve this objective, the Company agrees with other parties to exchange, at specified intervals, the difference between fixedhedges using interest rate swaps, “swaptions,” and floating interest amounts calculated on an agreed-upon notional principal amount.exchange-traded instruments. At December 31, 2017,2018, the Company had open interest rate swaps with maturity dates that extend to 2021.through 2022.

Foreign Currency Risk Management
The Company’s global operations requirenature of Dow's business requires active participation in the foreign exchange markets. The Company enters intohas assets, liabilities and cash flows in currencies other than the U.S. dollar. The primary objective of the Company's foreign currency risk management is to optimize the U.S. dollar value of net assets and cash flows. To achieve this objective, the Company hedges on a net exposure basis using foreign currency forward contracts, to hedge various currency exposures or create desired exposures.over-the-counter option contracts, cross-currency swaps and nonderivative instruments in foreign currencies. Exposures primarily relate to assets, liabilities and bonds denominated in foreign currencies, as well as economic exposure, which is derived from the risk that currency fluctuations could affect the dollar value of future cash flows related to operating activities. The primary business objective of the activity is to optimize the U.S. dollar value of the Company’s assets, liabilities and future cash flows with respect to exchange rate fluctuations. Assets and liabilities denominated in the same foreign currency are netted, and only the net exposure is hedged. At December 31, 2017,2018, the Company had foreign currency contracts with various expiration dates, through the fourth quarter of 2019.

Commodity Risk Management
The Company has exposure to the prices of commodities in its procurement of certain raw materials. The primary purpose of commodity hedging activities is to manage the price volatility associated with these forecasted inventory purchases. At December 31, 2017,2018, the Company had futures contracts, options and swaps to buy, sell or exchange commodities. These agreements hadhave various expiration dates through the fourth quarter of 2022.

Derivatives Not Designated in Hedging Relationships
Foreign Currency Contracts
The Company also uses foreign exchange forward contracts, options and cross-currency swaps that are not designated as hedging instruments primarily to manage foreign currency exposure.

Commodity Contracts
The Company utilizes futures, options and swap instruments that are effective as economic hedges of commodity price exposures, but do not meet hedge accounting criteria for derivatives and hedging, to reduce exposure to commodity price fluctuations on purchases of raw materials and inventory.

Interest Rate Contracts
The Company uses swap instruments that are not designated as hedging instruments to manage the interest rate exposures. Dow uses interest rate swaps, "swaptions," and exchange-traded instruments to accomplish this objective.

Accounting for Derivative Instruments and Hedging Activities
Cash Flow Hedges
For derivatives that are designated and qualify as cash flow hedging instruments, the effective portion of the gain or loss on the derivative is recorded in AOCL; it is reclassified to income in the same period or periods that the hedged transaction affects income. The unrealized amounts in AOCL fluctuate based on changes in the fair value of open contracts at the end of each reporting period. The Company anticipates volatility in AOCL and net income from its cash flow hedges. The amount of volatility varies with the level of derivative activities and market conditions during any period. Gains and losses on the derivatives representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current period income.

The Company had opennet gain from interest rate derivatives designated as cash flow hedges included in AOCL at December 31, 2017, with a net2018 was $23 million after tax (net loss of $3 million after tax (net loss of $4 million after tax at December 31, 2016)2017). These contracts have maturity dates that extend through 2022.

The Company had open foreign currency contracts designated as cash flow hedges of the currency risk associated with forecasted feedstock transactions not extending beyond 2019. The effective portion of the mark-to-market effects of the foreign currency contracts is recorded in AOCL; it is reclassified to income in the same period or periods that the underlying feedstock purchaseitem affects income. The net lossgain from the foreign currency hedges included in AOCL at December 31, 20172018 was $19$15 million after tax (net gainloss of $22$19 million after tax at December 31, 2016)2017). In 2017, 2016 and 2015, there was no material impact on the consolidated financial statements due to foreign currency hedge ineffectiveness.

Commodity swaps, futures and option contracts with maturities of not more than 60 months are utilized and designated as cash flow hedges of forecasted commodity purchases. Current open contracts hedge forecasted transactions until December 2022. The effectivedesignated portion of the mark-to-market effect of the cash flow hedge instrument is recorded in AOCL; it is reclassified to income in the same period or periods that the underlying commodity purchase affects income. The net loss from commodity hedges included in AOCL at December 31, 20172018 was $87 million after tax (net loss of $73 million after tax ($99 million after tax loss at December 31, 2016)2017). In 2017, 2016 and 2015, there was no material impact on the consolidated financial statements due to commodity hedge ineffectiveness.

Fair Value Hedges
For interest rate swap instruments that are designated and qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current period income and reflected as “Interest expense and amortization of debt discount” in the consolidated statements of income. The short-cut method is used when the criteria are met. In 2017, the Company entered into and subsequently terminated interest rate swaps designated as fair value hedges of underlying fixed rate debt obligations with maturity dates extending through 2024. The fair value adjustment resulting from these swaps was a loss on the derivative of $2 million. At December 31, 20172018 and 2016,2017, the Company had no open interest rate swaps designated as fair value hedges of underlying fixed rate debt obligations.

Net Foreign Investment Hedges
For derivative instruments that are designated and qualify as net foreign investment hedges, the effectivedesignated portion of the gain or loss on the derivative is included in “Cumulative Translation Adjustments”translation adjustments” in AOCL. The Company had outstanding foreign-currency denominated debt designated as a hedge of net foreign investment of $177$182 million at December 31, 20172018 ($172177 million at December 31, 2016)2017). The results of hedges of the Company’s net investment in foreign operations included in “Cumulative Translation Adjustments”translation adjustments” in AOCL was a net gain of $113 million after tax for the year ended December 31, 2018 (net loss of $76 million after tax for the year ended December 31, 2017 (net gain of $1 million after tax for2017).

Amounts to be Reclassified within the year ended December 31, 2016). In 2017, 2016 and 2015 there was no material impact on the consolidated financial statements due to hedge ineffectiveness.

Next Twelve Months
The net after-tax amounts to be reclassified from AOCL to income within the next 12 months are a $17$45 million loss for commodity contracts, a $19$13 million lossgain for foreign currency contracts and a $2$1 million lossgain for interest rate contracts.

1.Treasury bills, time deposits, and money market funds included in "Cash and cash equivalents" in the consolidated balance sheets and held at amortized cost, which approximates fair value.
2. Included in "Accounts and notes receivable – Other" in the consolidated balance sheets. See Note 14 for additional information on transfers of financial assets.
3. The Company’s investments in equity and debt securities, which are primarily classified as available-for-sale, and equity securities are included in “Other investments” in the consolidated balance sheets.
4. U.S. Treasury obligations, U.S. agency obligations, agency mortgage-backed securities and other municipalities’ obligations.
5. See Note 21 for the classification of derivatives in the consolidated balance sheets.
6. See Note 21 for information on fair value measurements of long-term debt.
For assets and liabilities 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. 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. See Note 21 for further information on the types of instruments used by the Company for risk management.
There were no transfers between Levels 1 and 2 in the years ended December 31, 20172018 and 2016.2017.

Table of Contents


For assets classified as Level 3 measurements, the fair value is based on significant unobservable inputs including assumptions where there is little, if any, market activity. The fair value of the Company’s interests held in trade accounts receivable conduits is determined by calculating the expected amount of cash to be received using the key input of anticipated credit losses in the portfolio of receivables sold that have not yet been collected. Given the short-term nature of the underlying receivables, discount rate and prepayments are not factors in determining the fair value of the interests. See Note 14 for further information on assets classified as Level 3 measurements.

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.
