CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Certain statements in this report are “forward‑looking statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Such statements often address expected future business and financial performance, financial condition, and other matters and often contain words or phrases such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “opportunity,” “outlook,” “plan,” “project,” “seek,” “should,” “strategy,” “target,” “will,” “will be,” “will continue,” “will likely result,” “would” and similar expressions, and variations or negatives of these words or phrases.

Forward-looking statements are based on current assumptions and expectations of future events that are subject to risks, uncertainties and other factors that are beyond the Corporation’s control, which may cause actual results to differ materially from those projected, anticipated or implied in the forward-looking statements and speak only as of the date the statements were made. These factors often address expected future business and financial performance and financial condition, including, but not limited to: the continuing global and regional economic impacts of the coronavirus disease 2019 pandemic and other public health-related risks and events on the Corporation’s business; and developments related to contemplated restructuring activities and proposed divestitures or acquisitions such as workforce reduction, manufacturing facility and/or asset closure and related exit and disposal activities, and the benefits and costs associated with each of the foregoing.

Where, in any forward-looking statement, an expectation or belief as to future results or events is expressed, such expectation or belief is based on the current plans and expectations of management and expressed in good faith and believed to have a reasonable basis, but there can be no assurance that the expectation or belief will result or be achieved or accomplished. A detailed discussion of principal risks and uncertainties which may cause actual results and events to differ materially from such forward-looking statements is included in the section of this Annual Report on Form 10-K titled “Risk Factors.” These are not the only risks and uncertainties that the Corporation faces. There may be other risks and uncertainties that the Corporation is unable to identify at this time or that it does not currently expect to have a material impact on its business. If any of those risks or uncertainties develops into an actual event, it could have a material adverse effect on the Corporation’s business. The Corporation assumes no obligation to update or revise publicly any forward-looking statements whether because of new information, future events, or otherwise, except as required by securities and other applicable laws.

Union Carbide Corporation and Subsidiaries
PART I


ITEM 1. BUSINESS

THE CORPORATION

Union Carbide Corporation is a chemicals and polymers company that has been a wholly owned subsidiary of The Dow Chemical Company ("TDCC") since 2001. Except as otherwise indicated by the context, the terms "Corporation" or "UCC" as used herein mean Union Carbide Corporation and its consolidated subsidiaries.

On April 1, 2019, DowDuPont Inc. (“DowDuPont” and effective June 3, 2019, n/k/a DuPont de Nemours, Inc.) completed the separation of its materials science business and Dow Inc. became the direct parent company of TDCC and its consolidated subsidiaries. The separation was contemplated by the merger of equals transaction effective August 31, 2017, under the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017. TDCC and E. I. du Pont de Nemours and Company and its consolidated subsidiaries ("Historical DuPont") each merged with subsidiaries of DowDuPont, and, as a result, TDCC and Historical DuPont became subsidiaries of DowDuPont (the “Merger”). Subsequent to the Merger, TDCC and Historical DuPont engaged in a series of internal reorganization and realignment steps to realign their businesses into three subgroups: agriculture, materials science and specialty products. This included transferring certain Corporation assets and liabilities aligned with the specialty products business to TDCC. Dow Inc. was formed as a wholly owned subsidiary of DowDuPont to serve as the holding company for the materials science business. UCC remains a wholly owned subsidiary of TDCC. See Note 3 to the Consolidated Financial Statements for additional information.

TDCC conducts its worldwide operations through global businesses. UCC's business activities comprise components of TDCC's global businesses rather than stand-alone operations. Because there are no separate reportable business segments for UCC and no detailed business information is provided to a chief operating decision maker regarding the Corporation's stand-alone operations, the Corporation's results are reported as a single operating segment. In addition, in order to simplify the customer interface process, the Corporation sells substantially all of its products to TDCC. Products are sold to TDCC at prices determined in accordance with the terms of an agreement between UCC and TDCC.

OTHER ACTIVITIES

Dividends

On a quarterly basis, the Corporation's Board of Directors ("Board") reviews and determines if there will be a dividend distribution to its parent company and sole shareholder, TDCC. The Board takes into consideration the level of earnings and cash flows, among other factors, in determining the amount of the dividend distribution. The Corporation declared and paid cash dividends of $362 million to TDCC in 2020; dividends paid to TDCC were $570 million in 2019. On February 2, 2021, the Board approved a dividend to TDCC of $40 million, payable on or before March 26, 2021.

In the first quarter of 2019, as part of the business separation activities to align TDCC's specialty products business with DowDuPont, UCC issued a stock dividend to TDCC for 63.4 percent of its ownership in Dow International Holdings Company, a cost method investment, which totaled $401 million. UCC also distributed assets and liabilities aligned with TDCC's specialty products business for an additional dividend to TDCC of $71 million.


ITEM 1A. RISK FACTORS

The factors described below represent the Corporation's principal risks.

COVID-19 PANDEMIC - RELATED RISKS

Public Health Crisis: A public health crisis or global outbreak of disease, including the pandemic caused by coronavirus disease 2019 (“COVID-19”) has had, and could continue to have, a negative effect on the Corporation's manufacturing operations, supply chain and workforce, creating disruptions that could continue to have a substantial negative impact on the Corporation’s results of operations, financial condition and cash flows.

UCC sells substantially all of its products to TDCC in order to simplify the worldwide customer interface process and, as a result, the Corporation is subject to many of the same global risk factors facing TDCC, including those presented by COVID-19. The pandemic caused by COVID-19 has impacted all geographic regions where UCC's products are produced and sold. The global, regional and local spread of COVID-19 has resulted in significant global mitigation measures, including government-directed quarantines, social distancing and shelter-in-place mandates, travel restrictions and/or bans, and restricted access to certain corporate facilities and manufacturing sites. Uncertainty with respect to the severity and duration of the COVID-19 pandemic, coupled with oil price fluctuations due in part to the global spread of COVID-19 and the continued increase in global cases, has contributed to the volatility of financial markets. While the severity and duration of the COVID-19 pandemic in key geographic regions and end-markets cannot be reasonably estimated at this time, impacts to the Corporation include, but are not limited to: a decrease in demand for certain Corporation products; price declines; reduced profitability; supply chain disruptions impeding the Corporation’s ability to ship and/or receive product; temporary idling or permanent closure of select manufacturing facilities and/or manufacturing assets; asset impairment charges; interruptions or limitations to manufacturing operations imposed by local, state or federal governments; workforce absenteeism and distraction; labor shortages; increased cyber security risk and data accessibility disruptions due to remote working arrangements; and workforce reductions. Additional risks may include, but are not limited to: shortages of key raw materials; additional asset impairment charges; increased obligations related to the Corporation’s pension and other postretirement benefit plans; and tax valuation allowances. Disruptions and market volatility resulting from the COVID-19 pandemic have had and could continue to have a substantial negative impact on the Corporation’s results of operations, financial condition and cash flows. The adverse impact of the COVID-19 pandemic on the Corporation may also have the effect of heightening many of the other risks described in this "Risk Factors" section.

MACROECONOMIC RISKS

Global Economic Considerations: The Corporation operates in a global, competitive environment, which gives rise to operating and market risk exposure.

The Corporation sells substantially all of its products to TDCC, which operates in a competitive, global environment, and competes worldwide for sales. Increased levels of competition could result in lower prices or lower sales volume, which could have a negative impact on the Corporation's results of operations. Sales of TDCC'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 Corporation's results of operations.

Table of Contents

Economic conditions around the world, and in certain industries in which the Corporation and TDCC do business, also impact sales price and volume. As a result, market uncertainty or an economic downturn in the geographic regions or industries in which UCC products are sold could reduce demand for these products and result in decreased sales volume, which could have a negative impact on UCC's results of operations.

Financial Flexibility: Market conditions could reduce TDCC's financial flexibility, which could impact the financial flexibility of the Corporation.

Adverse economic conditions could reduce TDCC'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 TDCC and could result in higher borrowing costs. Since TDCC is a service provider, material debtor, and the major customer of the Corporation, reduced financial flexibility for TDCC could potentially impact the financial flexibility of the Corporation.

Pension and Other Postretirement Benefits: Increased obligations and expenses related to the Corporation's defined benefit pension plans and other postretirement benefit plan could negatively affect UCC's financial condition and results of operations.

The Corporation has defined benefit pension plans and an other postretirement benefit plan (the "plans") in the United States. The assets of the Corporation'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 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 and health care cost trends may affect the funded status of the Corporation'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 Corporation's obligations or future funding requirements could have a negative impact on the Corporation's results of operations and cash flows for a particular period and on the Corporation's financial position.

Supply/Demand Balance: Earnings generated by the Corporation 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 Corporation's results of operations.

LEGAL AND REGULATORY RISKS

Environmental Compliance: The costs of complying with evolving regulatory requirements could negatively impact the Corporation'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 Corporation is subject to extensive federal, state, local and foreign laws, regulations, rules and ordinances relating to pollution, protection of the environment, climate change, greenhouse gas emissions and the generation, storage, handling, transportation, treatment, disposal and remediation of hazardous substances and waste materials. At December 31, 2020, the Corporation had accrued obligations of $133 million ($132 million at December 31, 2019) for probable environmental remediation and restoration costs, including $18 million ($20 million at December 31, 2019) 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 Corporation has accrued liabilities, although it is reasonably possible that the ultimate cost with respect to these particular matters could range up to approximately two and a half times that amount. 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 Corporation's operations, or require modifications to its facilities. Accordingly, environmental, health or safety regulatory matters could result in significant unanticipated costs or liabilities. For additional information, see Part II, Item 7. Other Matters, Environmental Matters in Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Table of Contents

Litigation: The Corporation is party to a number of claims and lawsuits arising out of the normal course of business with respect to commercial matters, including product liability, governmental tax and regulation disputes, and other actions.

The Corporation is involved in a number of legal proceedings and claims with both private and governmental parties. These cover a wide range of matters, including, but not limited to: product liability; trade regulation; governmental tax and regulatory proceedings; health, safety and environmental matters; employment matters; patent infringement; contracts; and commercial litigation. With the exception of the possible effect of the asbestos-related liability described below, it is the opinion of the Corporation's management that the possibility is remote that the aggregate of all such claims and lawsuits will have a material adverse impact on the Corporation's consolidated financial statements.

The Corporation 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, 2020, the Corporation's total asbestos-related liability for pending and future claims, including future defense and processing costs, was $1,098 million ($1,165 million at December 31, 2019). See Notes 1 and 14 to the Consolidated Financial Statements for more information on asbestos-related matters.

Health and Safety: Increased concerns regarding the safe use of chemicals and plastics in commerce and their potential impact on 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 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 and continued pressure for more stringent regulatory intervention and litigation. These concerns could also influence public perceptions, the viability or continued sales of the Corporation's products, the Corporation'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 Corporation'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.

Plastic Waste: Increased concerns regarding plastic waste in the environment, consumers selectively reducing their consumption of plastic products due to recycling concerns, or new or more restrictive regulations and rules related to plastic waste could reduce demand for the Corporation’s plastic products and could negatively impact the Corporation’s financial results.

Local, state, federal and foreign governments have been increasingly proposing and in some cases approving bans on certain plastic-based products including single-use plastics, plastic straws and utensils. In addition, plastics have faced increased public scrutiny due to negative coverage of plastic waste in the environment, including the world’s oceans. Substantially all of the Corporation's sales are to TDCC, which is one of the world’s largest producers of plastics. Therefore, increased regulation on the use of plastics could cause reduced demand for the Corporation’s polyethylene products which could negatively impact the Corporation's financial condition, results of operations and cash flows.

OPERATIONAL RISKS

Raw Materials: Availability of purchased feedstocks and energy, and the volatility of these costs, impact the Corporation's operating costs and add variability to earnings.

Purchased feedstock and energy costs account for a substantial portion of the Corporation's total production costs and operating expenses. The Corporation purchases hydrocarbon raw materials including ethane, propane, butane and naphtha as feedstocks. The Corporation also purchases certain monomers, primarily ethylene and propylene, to supplement internal production, as well as other raw materials. The Corporation purchases natural gas, primarily to generate electricity, and purchases electric power to supplement internal generation.

Table of Contents

Feedstock and energy costs generally follow price trends in crude oil and natural gas, which are sometimes volatile. 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 Corporation's results of operations.

While the Corporation expects abundant and cost-advantaged supplies of natural gas liquids ("NGLs") in the United States to persist for the foreseeable future, if NGLs become significantly less advantaged than crude oil-based feedstocks, it could have a negative impact on the Corporation's results of operations and future investments. Also, if the Corporation'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 Corporation's results of operations.

Operational Event: A significant operational event could negatively impact the Corporation's results of operations.

As a diversified chemical manufacturing company, the Corporation's operations, the transportation of products, cyber-attacks, pandemics 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 Corporation's results of operations.

Major hurricanes have caused significant disruption in UCC'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 UCC's products. Due to the Corporation's substantial presence on the U.S. Gulf Coast, similar severe weather conditions or other natural phenomena in the future could negatively impact UCC's results of operations.

Cyber Threat: The risk of loss of the Corporation's intellectual property, trade secrets or other sensitive business information or disruption of operations could negatively impact the Corporation's financial results.

Cyber-attacks or security breaches could compromise confidential, business critical information, cause a disruption in the Corporation's operations or harm the Corporation's reputation. The Corporation has attractive information assets, including intellectual property, trade secrets and other sensitive, business critical information. While the Corporation 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 Corporation's financial results.

Environmental Proceedings

On July 5, 2018, the Corporation received a draft consent decree from the U.S. Environmental Protection Agency, the U.S. Department of Justice and the Louisiana Department of Environmental Quality relating to the operation of steam-assisted flares at UCC's olefins manufacturing facility in Hahnville (St. Charles), Louisiana. On January 19, 2021, a proposed final consent decree was filed in the U.S. District Court for the Eastern District of Louisiana to address these matters. Notice of the consent decree was published in the Federal Register on January 28, 2021 and public comments are required to be submitted within 30 days of that publication. The consent decree would require the Corporation to pay approximately $900,000 in civil penalty and approximately $100,000 to specified local projects in Louisiana. The consent decree would further require the Corporation to install and operate additional air pollution control and monitoring technology on these steam-assisted flares at an estimated cost of approximately $120 million, to be completed over the next several years.

ITEM 6. SELECTED FINANCIAL DATA

Omitted pursuant to General Instruction I of Form 10‑K.


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

Pursuant to General Instruction I of Form 10-K "Omission of Information by Certain Wholly-Owned Subsidiaries," this section includes only management's narrative analysis of the results of operations for the year ended December 31, 2020, the most recent fiscal year, compared with the year ended December 31, 2019, the fiscal year immediately preceding it.

References below to "TDCC" refer to The Dow Chemical Company and its consolidated subsidiaries, except as otherwise indicated by the context. Union Carbide Corporation (the "Corporation" or "UCC") has been a wholly owned subsidiary of TDCC since 2001.

On April 1, 2019, DowDuPont Inc. (“DowDuPont” and effective June 3, 2019, n/k/a DuPont de Nemours, Inc.) completed the separation of its materials science business and Dow Inc. became the direct parent company of TDCC and its consolidated subsidiaries. The separation was contemplated by the merger of equals transaction effective August 31, 2017, under the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017. TDCC and E. I. du Pont de Nemours and Company and its consolidated subsidiaries ("Historical DuPont") each merged with subsidiaries of DowDuPont, and, as a result, TDCC and Historical DuPont became subsidiaries of DowDuPont (the “Merger”). Subsequent to the Merger, TDCC and Historical DuPont engaged in a series of internal reorganization and realignment steps to realign their businesses into three subgroups: agriculture, materials science and specialty products. This included transferring certain Corporation assets and liabilities aligned with TDCC's specialty products business to TDCC (the "Business Separation"). Dow Inc. was formed as a wholly owned subsidiary of DowDuPont to serve as the holding company for the materials science business. UCC remains a wholly owned subsidiary of TDCC.

TDCC conducts its worldwide operations through global businesses. UCC's business activities comprise components of TDCC’s global businesses rather than stand-alone operations. Because there are no separate reportable business segments for UCC and no detailed business information is provided to a chief operating decision maker regarding the Corporation’s stand-alone operations, the Corporation’s results are reported as a single operating segment.

Statement on COVID-19 and Oil Price Volatility

Overview of UCC’s Response to COVID-19

The pandemic caused by coronavirus disease 2019 ("COVID-19") has impacted all geographic regions where UCC’s products are produced and sold. Financial markets were volatile towards the end of the first quarter and early in the second quarter of 2020, primarily due to uncertainty with respect to the severity and duration of the pandemic, coupled with fluctuations in crude oil prices due in part to the global spread of COVID-19. As the second quarter progressed, crude oil prices increased, driven by improved supply and demand fundamentals, which continued into the second half of 2020. Financial markets also continued a gradual recovery in the second half of 2020.

Dow Inc. (together, with TDCC and its consolidated subsidiaries, “Dow”) directs global safety, crisis management and security protocols for all of Dow’s assets and workforce, which includes the assets and workforce of UCC.

Table of Contents

UCC’s primary manufacturing operations are in the United States, where efforts to contain the spread of COVID-19 resulted in significant mitigation measures, including social distancing and stay-at-home mandates, travel restrictions and/or bans, and restricted access to certain corporate facilities and manufacturing sites. The Corporation’s manufacturing facilities in the United States have been designated essential operations by state and local governments and all of UCC’s manufacturing sites and facilities, including its smaller sites in Asia Pacific, continue to operate and are doing so safely, having implemented social distancing and enhanced health, safety and sanitization measures as directed by Dow’s regional Crisis Management Teams (“CMTs”). The CMTs continue to work closely with site leadership and are adjusting alert levels as warranted on a site by site basis.

In the second quarter of 2020, the CMTs initiated implementation of Dow’s comprehensive Return to Workplace ("RTW") plan that is tailored for each site and includes a number of health and safety measures to be followed in a gradual and phased approach. A significant number of employees continue to work remotely as the Corporation and Dow monitors the pandemic evolution, awaiting acceptable and safe levels to implement its RTW phases. If ongoing mitigation efforts are successful, U.S. sites expect to implement additional RTW phases in the first and second quarters of 2021. The Corporation continues to encourage its workforce to practice safe behaviors in the workplace and while away from work to help prevent community spread of COVID-19.

During this public health crisis, UCC is focused on the health and safety of its employees, contractors, customers and suppliers around the world and maintaining safe and reliable operations of its manufacturing sites. Although supply disruptions and related logistical issues have posed challenges across all modes of transportation, UCC’s manufacturing sites have continued to operate during the COVID-19 pandemic, with no significant impact to manufacturing whether through shutdowns or shortages in labor, raw materials or personal protective equipment. Supply chain and logistical challenges are expected to stabilize in 2021. Contingency plans remain in place in the event of significant impacts from COVID-19 infection resurgences.

Dow took proactive measures to electively focus on cash and maintain financial strength with a continued emphasis on safe, reliable operations and disciplined capital allocation. In accordance with these actions, the Corporation reduced its 2020 capital expenditures target and temporarily idled one of the Corporation’s U.S. polyethylene production units to balance production to demand across markets more severely affected by restrained economic activity. The polyethylene production unit returned to more normalized operating rates in the third quarter of 2020. Further, on September 30, 2020, the Corporation's Board of Directors (the "Board") approved restructuring actions that were aligned to the structural cost improvement initiatives announced by Dow Inc. in response to the continued economic impact from the pandemic caused by COVID-19. The restructuring program is designed to reduce structural costs and enable the Corporation to further enhance competitiveness while the COVID-19 economic recovery gains traction. This program includes workforce cost reductions and actions to rationalize the Corporation's manufacturing assets. See Note 6 to the Consolidated Financial Statements for additional information.

Review of 2020 Financial Impacts from COVID-19

The Corporation's sales declined 15 percent in 2020 compared with 2019, as the COVID-19 pandemic disrupted the global economy and supply and demand fundamentals. The most significant impacts from the pandemic occurred in the first nine months of the year, with year-over-year sales declines of 18 percent, with a gradual yet uneven recovery beginning to take hold in the fourth quarter.

Local price declined in the first and second quarters of 2020, largely impacted by lower global energy prices. In March and April 2020, crude oil prices declined significantly, due in part to the COVID-19 pandemic, coupled with increased supply from oil producers, resulting in margin compression in the second quarter of 2020. Crude oil prices increased in the latter half of the second quarter as supply and demand fundamentals improved, driving higher feedstock costs, with the Corporation experiencing continued margin compression due to pricing pressures through the remainder of the year. See Results of Operations in this report for further discussion of 2020 operating results.

Table of Contents

At the time of this filing, the ultimate severity and duration of the COVID-19 pandemic cannot be reasonably estimated. The COVID-19 pandemic has had and could continue to have a substantial negative impact on the Corporation’s results of operations, financial condition and cash flows. The effects of the COVID-19 pandemic for the year ended December 31, 2020 and the additional risks associated with these conditions are more fully discussed in this report in Part II, Item 1A, Risk Factors. The Corporation is actively monitoring for potential financial impacts from the COVID-19 pandemic and oil price volatility, including, but not limited to: evaluating the recoverability of its assets; enhancing cyber security monitoring; and evaluating ongoing appropriateness of its estimates.

The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted on March 27, 2020 in the United States. There have been no significant impacts to the Corporation's provision for income taxes in 2020 as a result of the CARES Act legislation.

RESULTS OF OPERATIONS

Net Sales

Total net sales for 2020 were $3,703 million, compared with net sales of $4,377 million in 2019, a decrease of 15 percent. Net sales to related companies, principally to TDCC, were $3,574 million for 2020, compared with $4,239 million for 2019, a decrease of 16 percent. Selling prices to TDCC are determined in accordance with the terms of an agreement between UCC and TDCC.

Average selling price decreased 14 percent in 2020 compared with 2019 with price decreases across all products, primarily in response to lower feedstock and other raw material costs and resulting pricing pressures, with the largest decreases in polyethylene, oxo alcohols, plastics for wire and cable applications and glycol ethers. Volume was down 1 percent in 2020 compared with 2019, as decreases resulting from the divestiture of the Corporation's acetone derivatives product line, the Business Separation and polyethylene volume declines, resulting primarily from planned and unplanned outages, more than offset demand growth in home and personal care products and ethylene oxide/ethylene glycol.

Cost of Sales

Cost of sales in 2020 was $3,245 million, down 7 percent from $3,500 million in 2019. The decline in cost of sales was driven by lower feedstock and other raw material costs, lower volume, the divestiture of the Corporation's acetone derivatives product line, the impact of the Business Separation and a one-time charge of $55 million related to environmental remediation matters at a number of current and historical sites, recorded in the third quarter of 2019.

Research and Development, Selling, General and Administrative Expenses

Research and development expenses were $24 million in 2020, compared with $25 million in 2019. Selling, general and administrative expenses ("SG&A") were $9 million in 2020, compared with $4 million in 2019. The increase in SG&A expenses was driven in part by administrative fees associated with ongoing service arrangements.

Restructuring and Asset Related Charges - Net

2020 Restructuring Program

On September 30, 2020, the Board approved restructuring actions that were aligned to the structural cost improvement initiatives announced by Dow Inc. in response to the continued economic impact from the pandemic caused by COVID-19. The restructuring program is designed to reduce structural costs and enable the Corporation to further enhance competitiveness while the COVID-19 economic recovery gains traction. This program includes workforce cost reductions and actions to rationalize the Corporation's manufacturing assets. These actions are expected to be substantially complete by the end of 2021.

Table of Contents

2019 Asset Related Charges

On August 13, 2019, the Corporation entered into a definitive agreement to sell its acetone derivatives product line to ALTIVIA Ketones & Additives, LLC. As a result of this planned transaction, the Corporation recognized a pretax impairment charge of $75 million in the third quarter of 2019, which was included in "Restructuring and asset related charges - net" in the consolidated statements of income. The transaction closed November 1, 2019. See Notes 5 and 18 to the Consolidated Financial Statements for additional information.

Sundry Income (Expense) - Net

Sundry income (expense) – net includes a variety of income and expense items such as charges for management services provided by TDCC, commissions, non-operating pension and other postretirement benefit plan credits or costs and gains and losses on sales of investments and assets. Sundry income (expense) - net for 2020 was income of $168 million, compared with expense of $82 million in 2019. The increase in sundry income in 2020 was primarily the result of the sale of UCC's marine and terminal operations and assets at its site in St. Charles, Louisiana ("St. Charles"), which resulted in a pretax gain of $185 million, and the sale of UCC's rail infrastructure operations and assets at its sites in St. Charles and Seadrift, Texas, which resulted in a pretax gain of $86 million, partially offset by a pretax loss of $19 million on the early extinguishment of debt. See Notes 5, 7 and 13 to the Consolidated Financial Statements for additional information.

Interest Income

Interest income for 2020 was $12 million, compared with $36 million in 2019. The decrease in interest income primarily resulted from the impact of the significant drop in interest rates due to the current interest rate environment. See Note 19 to the Consolidated Financial Statements for additional information.

Interest Expense and Amortization of Debt Discount

Interest expense and amortization of debt discount was $33 million in 2020 compared with $30 million in 2019. The increase in interest expense and amortization of debt discount was primarily due to the recognition of interest and penalties related to the settlement of sales and use tax disputes in Seadrift, Texas, and Texas City, Texas, which was partially offset by reduced interest expense resulting from the early extinguishment of debt in September 2020. See Notes 13 and 19 to the Consolidated Financial Statements for additional information related to the Corporation's debt financing and cash management activities.

Provision for Income Taxes

The Corporation reported a tax provision of $130 million in 2020, which resulted in an overall effective tax rate of 23.3 percent. The tax rate for 2020 was unfavorably impacted by an accrual to return adjustment. In 2019, the Corporation reported a tax provision of $64 million, which resulted in an overall effective tax rate of 9.3 percent. The tax rate for 2019 was favorably impacted by the restoration of tax basis in assets, driven by a court judgment that did not involve the Corporation, and deductions allowed in the United States for certain sales to foreign customers. The underlying factors affecting UCC's overall effective tax rates are summarized in Note 8 to the Consolidated Financial Statements.

Net Income Attributable to UCC

The Corporation reported net income of $427 million in 2020, compared with net income of $627 million in 2019.

Capital Expenditures

Capital spending in 2020 was $135 million, compared with $196 million in 2019. Capital spending decreased in 2020 as spending for U.S. Gulf Coast projects and site infrastructure projects continues to trend down and the Corporation reduced its 2020 capital expenditures target to retain the financial strength of the Corporation and Dow Inc. in response to the COVID-19 pandemic.

In accordance with a proposed final consent decree filed on January 19, 2021, the Corporation would be required to install and operate additional air pollution control and monitoring technology on its steam-assisted flares at its olefins manufacturing facility in St. Charles. These installations are expected to result in additional capital expenditures of approximately $120 million, to be completed over the next several years. See Part I, Item 3, Legal Proceedings for more information on Environmental Proceedings.

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 preparation of the Consolidated Financial Statements. Following are the Corporation's accounting policies impacted by judgments, assumptions and estimates.

Litigation

The Corporation is subject to legal proceedings and claims arising out of the normal course of business. The Corporation routinely assesses the likelihood of any adverse judgments or 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, with the exception of asbestos-related matters, which is described in the following section. The Corporation has an active risk management program consisting of numerous insurance policies secured from many carriers. These policies provide coverage that is utilized to minimize the financial impact, if any, of the legal proceedings. The required reserves may change in the future due to new developments in each matter. For further discussion, see Note 14 to the Consolidated Financial Statements.

Asbestos-Related Matters

The Corporation 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 UCC sold in the past, alleged exposure to asbestos-containing products located on UCC’s premises, and UCC’s responsibility for asbestos suits filed against a former UCC subsidiary, Amchem Products, Inc. ("Amchem"). Each year, Ankura Consulting Group, LLC ("Ankura") performs a review for UCC based upon historical asbestos claims and resolution activity and historical defense spending. UCC 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 for pending and future claims, including future defense and processing costs, continues to be appropriate.

For additional information, see Part I, Item 3. Legal Proceedings; Asbestos-Related Matters in Management's Discussion and Analysis of Financial Condition and Results of Operations; and Notes 1 and 14 to the Consolidated Financial Statements.

Environmental Matters

The Corporation 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, 2020, the Corporation had accrued obligations of $133 million for probable environmental remediation and restoration costs, including $18 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 Corporation has accrued liabilities, although it is reasonably possible that the ultimate cost with respect to these particular matters could range up to approximately two and a half times that amount. For further discussion, see Environmental Matters in Notes 1 and 14 to the Consolidated Financial Statements.

Pension Plans 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, 2020, 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 17 to the Consolidated Financial Statements. 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.

Table of Contents

The Corporation uses 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. Under the spot rate approach, the Corporation calculates service cost and interest cost by applying individual spot rates from 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 the separate expected cash flow components of service cost and interest cost.

The Corporation 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 Corporation's historical experience with the pension fund asset performance is also considered. 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 2020 and 2019 was 6.8 percent. This assumption will also be used for determining 2021 net periodic pension expense. 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 Corporation's pension plans.

The discount rates utilized to measure the pension and other postretirement benefit obligations are based on the yield on high-quality corporate fixed income investments at the measurement date. Future expected actuarially determined cash flows for the 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 was 2.53 percent at December 31, 2020 and 3.29 percent at December 31, 2019.

The value of the qualified plan assets totaled $3.1 billion at December 31, 2020, unchanged from December 31, 2019. The underfunded status of the qualified plan increased by $185 million at December 31, 2020, compared with December 31, 2019. The Corporation did not make contributions to the qualified plan in 2020.

The assumption for the long-term rate of increase in compensation levels was 4.25 percent at December 31, 2020 and 2019. Since 2002, the Corporation has used a generational mortality table to determine the duration of its pension and other postretirement obligations.

The Corporation 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 plan, both gains and losses have been recognized and amortized. At December 31, 2020, $177 million of net gains remain to be recognized in the calculation of the market-related value of plan assets. These net gains will result in decreases in future pension expense as they are recognized in the market-related value of assets.

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


Net Increase in Market-Related Asset Value Due to Recognition of Prior Gains
In millions
2021	$	46
2022	23
2023	79
2024	29
Total	$	177

Table of Contents

At December 31, 2020, the Corporation expects pension expense to decrease in 2021 by approximately $15 million. The decrease in pension expense is primarily due to the lower interest cost component.

A 25 basis point adjustment in the long-term return on assets assumption would change total pension expense for 2021 by $7 million. A 25 basis point adjustment in the discount rate assumption would have an immaterial impact on the total pension expense for 2021.

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 Corporation recognizes future tax benefits, such as net operating loss carryforwards and tax credit carryforwards, to the extent that realizing these benefits is considered more likely than not.

At December 31, 2020, the Corporation had a net deferred tax asset balance of $494 million, after valuation allowances of $18 million. In evaluating the ability to realize the deferred tax assets, the Corporation 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, 2020, the Corporation had deferred tax assets for tax loss and tax credit carryforwards of $34 million, of which $21 million is subject to expiration in the years 2021 through 2025. In order to realize these deferred tax assets for tax loss and tax credit carryforwards, the Corporation needs taxable income of approximately $1,121 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 2021 and 2025 is $406 million.

The Corporation recognizes the financial statement effects of an uncertain tax position when it is more likely than not, based on technical merits, that the position will be sustained upon examination. At December 31, 2020, the Corporation had a liability for uncertain tax positions of $1 million.

The Corporation 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, 2020, the Corporation had an immaterial tax contingency reserve. For additional information, see Note 8 to the Consolidated Financial Statements.

Environmental Matters

Environmental Policies

The Corporation is committed to world-class environmental, health and safety ("EH&S") performance, as demonstrated by a long-standing commitment to Responsible Care®, as well as a strong commitment to Dow Inc.'s 2025 Sustainability Goals - goals that set the standard for sustainability in the chemical industry by focusing on improvements in UCC's local corporate citizenship and product stewardship, and by actively pursuing methods to reduce the Corporation's environmental impact.

The EH&S management system ("EMS") defines the "who, what, when and how" needed for the Corporation to achieve the policies, requirements, performance objectives, leadership expectations and public commitments. EMS is also designed to minimize the long-term cost of environmental protection and to comply with applicable laws and regulations. To ensure effective utilization, EMS is integrated into a company-wide management system for EH&S, Operations, Quality and Human Resources, including implementation of the global EH&S Work Process to improve EH&S performance and to ensure ongoing compliance worldwide.

The Corporation adheres to a waste management hierarchy that minimizes the impact of wastes and emissions on the environment. UCC first works to eliminate or minimize the generation of waste and emissions at the source through research, process design, plant operations and maintenance. Next, UCC 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. UCC has specific requirements for waste that is transferred to non-UCC facilities, including the periodic auditing of these facilities.

Chemical Security

Public and political attention continues to be placed on the protection of U.S. critical infrastructure, including the chemical industry, from security threats. Terrorist attacks and natural disasters have increased global concerns about the security and safety of chemical production and distribution. UCC continues to improve its security plans, placing emphasis on the safety of UCC communities and people by being prepared to meet risks at any level and to address both internal and external identifiable risks. UCC's security plans are designed to avert interruptions of normal business operations that could have a material impact on the Corporation's results of operations, financial condition and cash flows.

UCC is a Responsible Care® company and adheres to the Responsible Care® Security Code, which requires that all aspects of security - including facility, transportation and cyberspace - be assessed and gaps addressed. Through global implementation of the Security Code, including voluntary security enhancements and upgrades, UCC has permanently heightened its level of security - not just in the United States, but worldwide. Further, the Corporation’s Distribution Risk Review process addresses potential threats in all modes of transportation across the Company’s supply chain. In 2019, Dow Inc. established its Global Security Operations Center ("GSOC") to provide 24-hour/day, 365-day/year real-time monitoring of global risks to Dow Inc. assets and people, which includes UCC assets and people. The GSOC employs state-of-the-art social media monitoring, threat reporting and geo-fencing capabilities to analyze global risks and report those risks, facilitating decision-making and actions to prevent Dow Inc. and UCC crises.

To reduce vulnerabilities, UCC maintains security measures that meet or exceed regulatory and industry security standards in all areas in which UCC operates. Assessment and improvement costs are not considered material to the Corporation's consolidated financial statements.

Climate Change

Climate change matters for UCC are likely to be driven by several categories of risks related to the transition to a lower-carbon economy (“Transition Risks”) and risks related to the physical impacts of climate change (“Physical Risks”).

Transition Risks

Transition Risks include carbon pricing mechanisms, a transition to lower emissions technology, increased cost of raw materials, and mandates on and regulation of existing products and services. Carbon pricing is a market-based strategy for lowering global warming emissions by putting a monetary value on carbon emissions so the costs of climate impacts and opportunities for low-carbon energy options are reflected in production and consumption choices.

Carbon pricing mechanisms will not only increase UCC’s direct costs to operate but will also result in increased energy costs. UCC mitigates the direct cost impact of existing regulation through research and development projects designed to increase energy efficiency and capital investment projects that will reduce the Corporation’s energy usage and carbon footprint.

Physical Risks

Operationally, climate change may result in more frequent severe weather events, potential changes in precipitation patterns and extreme variability in weather patterns, which can disrupt operations. The Corporation has engineered susceptible facilities, particularly on the U.S. Gulf Coast, to better withstand severe weather and rising sea levels, and continues to study the long-term implications of changing climate parameters on water availability, plant siting issues and other impacts. 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.

The Corporation continues to elevate its internal focus and external positions to focus on the root cause of greenhouse gas ("GHG") emissions, including the sustainable use of energy. Through Dow’s energy efficiency programs and focused GHG management efforts, the Corporation has and is continuing to reduce its GHG emissions footprint.

Table of Contents

Environmental Remediation

UCC accrues the costs of remediation of its facilities and formerly owned facilities based on current law and existing technologies. The nature of such remediation includes, for example, the management of soil and groundwater contamination. The 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 consolidated 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 emerging remediation technologies. These liabilities are adjusted periodically as remediation efforts progress or as additional technical or legal information becomes available. The Corporation had an accrued liability of $115 million at December 31, 2020 and $112 million at December 31, 2019, related to the remediation of current or former UCC-owned sites.

In addition to current and former UCC-owned sites, under the Federal Comprehensive Environmental Response, Compensation and Liability Act and equivalent state laws (hereafter referred to collectively as "Superfund Law"), UCC is liable for remediation of other hazardous waste sites where UCC 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, UCC 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. Management's estimate of the Corporation's remaining liability for the remediation of Superfund sites was $18 million at December 31, 2020 and $20 million at December 31, 2019, which has been accrued, although the ultimate cost with respect to these sites could exceed that amount. The Corporation has not recorded any third-party recovery related to these sites as a receivable.

Information regarding environmental sites is provided below:


Environmental Sites	UCC-owned Sites 1		Superfund Sites 2

Sites added during year	—	—	—	1
Sites closed during year	—	—	(1)	(2)
Number of sites at Dec 31	25	25	66	67

1.UCC-owned sites are sites currently or formerly owned by UCC. In the United States, remediation obligations are imposed by the Resource Conservation and Recovery Act or analogous state law.

2.Superfund sites are sites, including sites not owned by UCC, where remediation obligations are imposed by Superfund Law.

In total, the Corporation's accrued liability for probable environmental remediation and restoration costs was $133 million at December 31, 2020, compared with $132 million at December 31, 2019. This is management's best estimate of the costs for remediation and restoration with respect to environmental matters for which the Corporation has accrued liabilities, although it is reasonably possible that the ultimate cost with respect to these particular matters could range up to approximately two and a half 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 Corporation's results of operations, financial condition and cash flows. It is the opinion of the Corporation's management, however, that the possibility is remote that costs in excess of the range disclosed will have a material impact on the Corporation's results of operations, financial condition and cash flows.

In the third quarter of 2019, the Corporation recorded a pretax charge of $55 million, included in "Cost of sales" in the consolidated statements of income, related to environmental remediation matters at a number of current and historical locations. The charge primarily resulted from the culmination of long-standing negotiations and discussions with regulators and agencies, including technical studies supporting higher cost estimates for final or staged remediation plans, and the Corporation’s review of its closure strategies and obligations to monitor ongoing operations and maintenance activities.

The amounts charged to income on a pretax basis related to environmental remediation totaled $49 million in 2020, $93 million in 2019 and $38 million in 2018. The amounts charged to income on a pretax basis related to operating the Corporation's pollution abatement facilities, excluding internal recharges, totaled $98 million in 2020,

Table of Contents

$109 million in 2019 and $113 million in 2018. Capital expenditures for environmental protection were $5 million in 2020, $11 million in 2019 and $9 million in 2018.

Asbestos-Related Matters

The Corporation 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 UCC sold in the past, alleged exposure to asbestos-containing products located on UCC's premises, and UCC's responsibility for asbestos suits filed against a former UCC 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 UCC's products.

The table below provides information regarding asbestos-related claims pending against the Corporation and Amchem based on criteria developed by UCC and its external consultants:


Asbestos-Related Claim Activity	2020	2019	2018
Claims unresolved at Jan 1	11,117	12,780	15,427
Claims filed	4,857	5,743	6,599
Claims settled, dismissed or otherwise resolved	(6,848)	(7,406)	(9,246)
Claims unresolved at Dec 31	9,126	11,117	12,780
Claimants with claims against both UCC and Amchem	(2,904)	(3,837)	(4,675)
Individual claimants at Dec 31	6,222	7,280	8,105

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 UCC, 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 personal injury cases in which only the Corporation and/or Amchem are the sole named defendants. For these reasons and based upon the Corporation's litigation and settlement experience, the Corporation does not consider the damages alleged against it and Amchem to be a meaningful factor in its determination of any potential asbestos-related liability.

For additional information, see Part I, Item 3. Legal Proceedings and Asbestos-Related Matters in Notes 1 and 14 to the Consolidated Financial Statements.

Debt Covenants and Default Provisions

The Corporation's outstanding public debt has been issued under indentures which contain, among other provisions, covenants that the Corporation must comply with while the underlying notes are outstanding. Such covenants are typically based on the Corporation's size and financial position and include, subject to the exceptions and qualifications contained in the indentures, obligations not to (i) allow liens on principal U.S. manufacturing facilities, (ii) enter into sale and lease-back transactions with respect to principal U.S. manufacturing facilities, or (iii) merge into or consolidate with any other entity or sell or convey all or substantially all of its assets. Failure of the Corporation to comply with any of these covenants could, after the passage of any applicable grace period, result in a default under the applicable indenture which would allow the note holders to accelerate the due date of the outstanding principal and accrued interest on the subject notes. Management believes the Corporation was in compliance with the covenants referred to above at December 31, 2020.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

UCC’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 Corporation 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.

The global nature of UCC’s business requires active participation in the foreign exchange markets. As a result of investments, production facilities and other operations on a global basis, the Corporation has assets, liabilities and cash flows in currencies other than the U.S. dollar. The primary objective of the Corporation’s foreign exchange risk management is to optimize the U.S. dollar value of net assets and cash flows. To achieve this objective, the Corporation 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 cash flows denominated in foreign currencies. The largest exposures are denominated in the Canadian dollar as well as the currencies of Europe and Asia Pacific.

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

UCC 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 Corporation is a variance/covariance model. This model uses a 97.5 percent confidence level and includes at least one year of historical data. The 2020 and 2019 year-end and average daily VAR for the aggregate of all positions are shown below:

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholder and the Board of Directors of Union Carbide Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Union Carbide Corporation and subsidiaries (the "Corporation") as of December 31, 2020 and 2019, the related consolidated statements of income, comprehensive income, equity, and cash flows, for each of the three years in the period ended December 31, 2020, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Corporation as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

Changes in Accounting Principles

As discussed in Note 1 to the financial statements, in the first quarter of 2019, the Corporation changed the method of accounting for leases due to the adoption of ASC Topic 842, Leases.

Basis for Opinion

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

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Corporation is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Corporation’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which they relate.

Asbestos – Refer to Note 1 and Note 14 to the Financial Statements

Critical Audit Matter Description

The Corporation is and has been involved in a large number of asbestos-related suits filed primarily in state courts during the past four decades. The Corporation expects more asbestos-related suits to be filed against the

Table of Contents

Corporation and its former subsidiary Amchem Products, Inc. in the future, and will aggressively defend or reasonably resolve, as appropriate, both pending and future claims. Since 2003, the Corporation has engaged a third-party actuarial specialist to review the Corporation's historical asbestos-related claim and resolution activity in order to assist management in estimating the Corporation's asbestos-related liability. The Corporation considers quantitative and qualitative factors such as the nature of pending claims, trial experience of the Corporation and other asbestos defendants, current spending for defense and processing costs, significant appellate rulings and legislative developments, trends in the tort system, and their respective effects on expected future resolution costs.

The Corporation considers the following summarized assumptions and judgments in arriving at the estimated liability:

•The average resolution value calculated by the Corporation to settle each pending and future claim

•The Corporation’s estimation of the number of pending and future claims

•The curve of how claims will occur over the estimated period through the terminal year

•The estimated terminal year 2049 (date at which future claims will cease)

Given the significant judgments made by management to estimate the asbestos liability, performing audit procedures to evaluate the reasonableness of management’s estimates and assumptions related to average resolution value of pending and future claims, estimated number of pending and future claims, valuation of future claims, curve of how claims will occur, and estimated terminal date required a high degree of auditor judgment and an increased extent of effort, including the need to involve our actuarial specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to management’s estimate and assumptions of the asbestos liability included the following, among others:

•We tested the effectiveness of internal controls related to the asbestos liability including management’s controls over the determination of average resolution value of pending and future claims, estimated number of claims, valuation of future claims, curve of how claims will occur, and the estimated terminal date.

•We evaluated the methods and assumptions used by management to estimate the asbestos liability by:

◦Testing the underlying data that served as the basis for the actuarial analysis, including historical claims, to test that the inputs to the actuarial estimate were reasonable.

◦Comparing management’s prior-year assumptions of expected development and ultimate loss to actuals incurred during the current year to identify potential bias in the determination of the asbestos-related liabilities.

•With the assistance of our actuarial specialists, we developed independent estimates of the asbestos-related liabilities, including loss data and industry claim development factors, and compared our estimates to management’s estimates.

•We read external information included in regulatory filings and news releases to search for contradictory evidence.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation and Basis of Presentation

Except as otherwise indicated by the context, the terms "Corporation" and "UCC" as used herein mean Union Carbide Corporation and its consolidated subsidiaries. The accompanying consolidated financial statements of the Corporation 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 Corporation exercises control and, when applicable, entities for which the Corporation has a controlling financial interest. Investments in nonconsolidated affiliates (20-50 percent owned companies, joint ventures and partnerships) are accounted for using the equity method.

The Corporation is a wholly owned subsidiary of The Dow Chemical Company ("TDCC"). 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.

TDCC conducts its worldwide operations through global businesses. The Corporation’s business activities comprise components of TDCC’s global businesses rather than stand-alone operations. Because there are no separate reportable business segments for UCC under the accounting guidance related to segment reporting and no detailed business information is provided to a chief operating decision maker regarding the Corporation’s stand-alone operations, the Corporation’s results are reported as a single operating segment.

Table of Contents

("Historical DuPont") each merged with subsidiaries of DowDuPont, and, as a result, TDCC and Historical DuPont became subsidiaries of DowDuPont (the “Merger”). Subsequent to the Merger, TDCC and Historical DuPont engaged in a series of internal reorganization and realignment steps to realign their businesses into three subgroups: agriculture, materials science and specialty products. Dow Inc. was formed as a wholly owned subsidiary of DowDuPont to serve as the holding company for the materials science business. UCC remains a wholly owned subsidiary of TDCC. See Note 3 for additional information.

Intercompany transactions and balances are eliminated in consolidation. Transactions with the Corporation’s parent company, TDCC, and other subsidiaries of TDCC, have been reflected as related company transactions in the consolidated financial statements. See Note 19 for additional information.

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 Corporation'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 "Asbestos-related liabilities - current" and "Asbestos-related liabilities - noncurrent." See Note 14 for additional information.

Legal Costs

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

Foreign Currency Translation

While the Corporation's consolidated subsidiaries are primarily based in the United States, the Corporation has small subsidiaries in Asia Pacific and the rest of the world. For those subsidiaries, the local currency has been primarily used as the functional currency. 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"). 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 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 Corporation calculates the fair value of financial instruments using quoted market prices when available. When quoted market prices are not available for financial instruments, the Corporation uses standard pricing models with market-based inputs that take into account the present value of estimated future cash flows.

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.

The Corporation 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 are carried at cost less accumulated depreciation. Property under finance lease agreements is carried at the present value of lease payments over the lease term less accumulated amortization. Depreciation is based on the estimated service lives of depreciable assets and is calculated using the straight-line method. Fully depreciated assets are retained in property and accumulated depreciation accounts until they are removed from service. 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 Corporation 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.

Other Intangible Assets

Finite-lived intangible assets, such as developed technology and software, are amortized over their estimated useful lives, generally on a straight-line basis for periods ranging primarily from three to twenty years.

Asset Retirement Obligations

The Corporation 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 Corporation. 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 in Related Companies

Investments in related companies consist of the Corporation's ownership interests in TDCC subsidiaries located in the United States and Latin America. The Corporation accounts for these investments using the cost method as it does not have significant influence over the operating and financial policies of these related companies.

Leases

Effective January 1, 2019, UCC adopted Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)," and the associated ASUs (collectively, "Topic 842"). The Corporation added the following significant accounting policy for leases as a result of the adoption of Topic 842:

UCC determines whether a contract contains a lease at contract inception. A contract contains a lease if there is an identified asset and the Corporation has the right to control the asset. Operating lease right-of-use (“ROU”) assets represent UCC’s right to use an underlying asset for the lease term, and lease liabilities represent UCC’s obligation

Table of Contents

to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. UCC uses the incremental borrowing rate in determining the present value of lease payments, unless the implicit rate is readily determinable. If lease terms include options to extend or terminate the lease, the ROU asset and lease liability are measured based on the reasonably certain decision. Leases with a term of 12 months or less at the commencement date are not recognized on the balance sheet and are expensed as incurred.

UCC has lease agreements with lease and non-lease components, which are accounted for as a single lease component for nearly all classes of leased assets for which UCC is the lessee. Additionally, for certain equipment leases, the portfolio approach is applied to account for the operating lease ROU assets and lease liabilities. In the consolidated statements of income, lease expense for operating lease payments is recognized on a straight-line basis over the lease term. For finance leases, interest expense is recognized on the lease liability and the ROU asset is amortized over the lease term.

Some leasing arrangements require variable payments that are dependent upon usage or output, or may vary for other reasons, such as insurance or tax payments. Variable lease payments are recognized as incurred and are not presented as part of the ROU asset or lease liability. See Note 15 for additional information.

Revenue

Substantially all of the Corporation's revenues are generated by sales to TDCC. Revenue for product sales to related companies is recognized when the related company obtains control of the product, which occurs either at the time that production is complete or shipped free on board ("FOB") from UCC's manufacturing facility, in accordance with the sales agreement between the Corporation and TDCC. The Corporation recognizes revenue for product sales to trade customers when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the Corporation expects to receive in exchange for those goods or services. To determine revenue recognition, the Corporation performs the following five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. See Note 4 for additional information.

Severance Costs

Management routinely reviews its operations around the world in an effort to ensure competitiveness across its operations 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 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 Corporation classifies expenses related to the Merger and separation as integration and separation costs. Merger and separation related costs include: post-Merger integration expenses and costs incurred for the separation of TDCC’s agriculture business, materials science business and specialty products business. Integration and separation costs primarily consist of financial advisor, information technology, legal, accounting, consulting and other professional advisory fees associated with preparation and execution of these activities. Integration and separation costs related to the Merger and separation were completed as of December 31, 2020.

Income Taxes

The Corporation 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 Corporation is included in the same consolidated federal income tax group and consolidated income tax return as TDCC. The Corporation accounts for its income taxes following the formula in the TDCC-UCC Tax Sharing Agreement used to compute the amount due to TDCC or UCC for UCC's share of taxable income and tax attributes on the consolidated income tax return. This method generally follows the separate return method. The amounts reported as income taxes payable or receivable represent the Corporation's payment obligation (or refundable amount) to TDCC based on a theoretical tax liability calculated on a separate return method.

Table of Contents

The Corporation 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 Corporation 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.

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.

Changes in Financial Statement Presentation

Consolidated Statements of Income

In 2019, the Corporation made a change to separately report "Interest income" which had previously been included in "Sundry income (expense) - net" in the consolidated statements of income.

Consolidated Statements of Equity

The adoption of ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" ("ASU 2018-02") in 2018 resulted in a $254 million increase to "Retained earnings" due to the reclassification from "Accumulated other comprehensive loss" for the effect of the federal corporate income tax rate change as a result of the Tax Cuts and Jobs Act of 2017 ("The Act") on the Corporation's pension plans. This adoption is reflected in the "Adoption of accounting standard" line in the consolidated statements of equity.

NOTE 2 - RECENT ACCOUNTING GUIDANCE

Recently Adopted Accounting Guidance

In the third quarter of 2020, the Corporation adopted ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The amendments provide optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The new standard is effective March 12, 2020 through December 31, 2022, with the adoption date dependent upon the Corporation’s election. The Corporation has elected to apply the optional expedients and exceptions provided by the new guidance as modifications are made to relevant contracts, hedging relationships and other transactions during the reference rate reform transition period. As the amendments are intended to ease the potential burden in accounting for, or recognizing the effects of, reference rate reform on financial reporting, the application of this guidance has not and will not have a material impact on the consolidated financial statements.

Accounting Guidance Issued But Not Adopted at December 31, 2020

In December 2019, the Financial Accounting Standards Board issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." The amendments simplify the accounting for income taxes by removing certain exceptions to the general principles of Topic 740, "Income Taxes" and improve consistent application by clarifying and amending existing guidance. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted, with the amendments to be applied on a retrospective, modified retrospective or prospective basis, depending on the specific amendment. The Corporation will adopt the new guidance in the first quarter of 2021 and the adoption is not expected to have a material impact on the consolidated financial statements.

NOTE 3 - BUSINESS SEPARATION

In the first quarter of 2019, in anticipation of DowDuPont's intended separation of its materials science business, UCC's assets and liabilities aligned with TDCC's specialty products business were transferred to TDCC as part of the internal reorganization steps to align TDCC's specialty products business to DowDuPont. In order to align entity ownership under TDCC, UCC distributed shares and assets to TDCC through dividends or asset distributions. As a result, in February 2019, UCC issued to TDCC a dividend of 1,067 shares of common stock of Dow International Holdings Company (“DIHC”), a cost method investment. Prior to the distribution, UCC had an 11.9 percent ownership interest in DIHC with the other 88.1 percent owned by TDCC and its other wholly owned subsidiaries. After the dividend, UCC’s investment in DIHC was reduced to 4.7 percent and resulted in a reduction in "Investments in related companies" of $401 million. UCC also transferred, as an asset distribution, the assets and liabilities aligned with TDCC's specialty products business for an additional dividend of $71 million to TDCC. The results of these transactions are reflected in “Investments in related companies” and “Retained earnings” in the consolidated balance sheets. See Note 19 for additional information.

Table of Contents

The Corporation evaluated the impact of the specialty products product line transfer and determined it did not represent a strategic shift that had a major effect on the Corporation’s operations and financial results and did not qualify as an individually significant component of the Corporation. As a result, this transfer was not reported as discontinued operations.

NOTE 4 - REVENUE

Substantially all of the Corporation's revenue is generated by sales to TDCC. Products are sold to and purchased from TDCC at prices determined in accordance with the terms of an agreement between UCC and TDCC. The Corporation's revenue related to sales of product was approximately 98 percent in 2020 (99 percent in 2019 and 2018); the remaining revenue primarily related to the licensing of patents and technology. The Corporation sells its products to TDCC to simplify the customer interface process.

Substantially all product sale contracts are short-term in nature and have original expected durations of one year or less. Revenue from product sales is recognized when TDCC or the customer obtains control of the Corporation’s product, which occurs at a point in time, typically at the time production is complete or product is shipped FOB from UCC’s manufacturing facility for sales to TDCC, or upon shipment for sales to trade customers. The Corporation’s payment terms are on average 30 to 60 days after invoicing. All shipping and handling activities that occur after control transfers to the customer are considered fulfillment activities. Certain long-term contracts include a series of distinct goods that are delivered continuously to the customer through a pipeline. For these types of product sales, the Corporation invoices the customer in an amount that directly corresponds with the value to the customer of the Corporation’s performance to date. As a result, revenue is recognized based on the amount billable to the customer in accordance with the right to invoice practical expedient.

The transaction price for product sales includes estimates for the most likely amount of consideration to which the Corporation will be entitled based on historical award experience and the Corporation’s best judgment at the time. Taxes collected and remitted to governmental authorities are excluded from the transaction price. For contracts with multiple performance obligations, the Corporation allocates the transaction price to each performance obligation on the basis of relative standalone selling price, which is based on the price charged to customers or estimated using the expected cost plus margin method.

Revenue related to the initial licensing of patents and technology is recognized when the performance obligation is satisfied. Revenue related to sales-based royalties to which the Corporation expects to be entitled is estimated based on historical sales.

The Corporation’s contract liabilities include payments received in advance of performance under long-term contracts for product sales and royalties with remaining contract terms that range up to 21 years. Amounts are recognized in revenue when the performance obligations for the contract are met. The Corporation has rights to additional consideration when product is delivered to the customer. The balance of contract liabilities was $40 million at December 31, 2020 ($41 million at December 31, 2019), of which $5 million ($4 million at December 31, 2019) was included in "Accrued and other current liabilities" and $35 million ($37 million at December 31, 2019) was included in "Other noncurrent obligations" in the consolidated balance sheets.

The Corporation disaggregates its revenue from contracts with customers by type of customer (sales to related parties and sales to trade customers) as presented on the consolidated statements of income and believes this disaggregation best depicts the nature, amount, timing and uncertainty of its revenue and cash flows. Substantially all of the product sales are made to the Corporation's parent company, TDCC, and there are no unique economic factors that affect revenue recognition and cash flows associated with these product sales.

NOTE 5 - DIVESTITURES

Divestiture of Rail Infrastructure Operations and Assets

On July 2, 2020, TDCC entered into a definitive agreement to sell its rail infrastructure operations and assets at certain sites in the U.S. and Canada to an affiliate of Watco Companies, L.L.C. ("Watco affiliate") and the transaction closed September 30, 2020. As part of this transaction, UCC sold its related operations and assets, including existing agreements to provide rail services to unrelated third parties, located at its sites in St. Charles, Louisiana ("St. Charles"), and Seadrift, Texas, with a net book value of $9 million, to the Watco affiliate. UCC retained ownership of the sites and underlying real property where the divested operations are located. UCC and the Watco affiliate entered into mutual long-term service agreements designed to ensure the continuation of rail services for UCC's existing operations at the impacted sites. The rail-service agreements include variable fees that have an initial term of 25 years. As part of the sale, UCC received proceeds of $95 million from TDCC, subject to customary post-closing adjustments, and recognized a pretax gain on the sale of $86 million, included in "Sundry income (expense) - net" in the consolidated statements of income. See Note 19 for more information on the cash management process.

The Corporation evaluated the divestiture of the rail infrastructure operations and assets and determined it did not represent a strategic shift that had a major effect on the Corporation’s operations and financial results and did not qualify as an individually significant component of the Corporation. As a result, the divestiture is not reported as discontinued operations.

Divestiture of Marine and Terminal Operations and Assets

On September 14, 2020, TDCC entered into a definitive agreement to sell certain U.S. Gulf Coast marine and terminal operations and assets, including certain operations and assets located at UCC's site in St. Charles, to an affiliate of Royal Vopak ("Vopak affiliate"), and the transaction closed December 1, 2020. As part of this transaction, UCC sold certain related operations and assets located at its St. Charles site, including existing agreements to provide marine and terminal services to unrelated third parties, with a net book value of $41 million to the Vopak affiliate. UCC retained ownership of the site and the underlying real property where the divested operations are located. UCC and the Vopak affiliate entered into mutual long-term service agreements designed to ensure the continuation of marine and terminal services for UCC's existing St. Charles operations. The marine and terminal service agreements include fixed and variable fees that have initial terms of up to 25 years. Certain of these agreements contain leases, resulting in operating lease ROU assets and lease liabilities of $38 million. As part of the sale, UCC received proceeds of $226 million from TDCC, subject to customary post-closing adjustments, and recognized a pretax gain on the sale of $185 million, included in "Sundry income (expense) - net" in the consolidated statements of income. See Note 15 for additional information related to leases and Note 19 for additional information on the cash management process.

The Corporation evaluated the divestiture of the marine and terminal operations and assets and determined it did not represent a strategic shift that had a major effect on the Corporation’s operations and financial results and did not qualify as an individually significant component of the Corporation. As a result, the divestiture is not reported as discontinued operations.

Divestiture of Acetone Derivatives Assets

On November 1, 2019, the Corporation completed the sale of its acetone derivatives product line to ALTIVIA Ketones & Additives, LLC for net proceeds of $17 million. The sale included acetone derivatives related inventory and production assets, as well as site infrastructure, land and utilities located in Institute, West Virginia. The sale also included railcars valued at $3 million, which were previously owned by TDCC and transferred to UCC in anticipation of the sale. The assets, with the exception of inventory and railcars, were written down to zero in the third quarter of 2019. In the fourth quarter of 2019, the Corporation recorded a $5 million pretax loss on the sale, included in "Sundry income (expense) - net" in the consolidated statements of income. The Corporation remains at the Institute, West Virginia, site as a tenant. See Notes 6 and 18 for additional information.

The Corporation evaluated the divestiture of the acetone derivatives product line and determined it did not represent a strategic shift that had a major effect on the Corporation’s operations and financial results and did not qualify as an individually significant component of the Corporation. As a result, this divestiture was not reported as discontinued operations.

NOTE 6 - RESTRUCTURING AND ASSET RELATED CHARGES - NET

2020 Restructuring Program

On September 30, 2020, the Corporation's Board of Directors (the "Board") approved restructuring actions that were aligned to the structural cost improvement initiatives announced by Dow Inc. in response to the continued economic impact from the pandemic caused by coronavirus disease 2019 ("COVID-19"). The restructuring program is designed to reduce structural costs and enable the Corporation to further enhance competitiveness while the COVID-19 economic recovery gains traction. This program includes workforce cost reductions and actions to rationalize the Corporation's manufacturing assets. These actions are expected to be substantially complete by the end of 2021.

As a result of these actions, in the third quarter of 2020, the Corporation recorded pretax restructuring charges of $13 million, consisting of severance and related benefit costs of $9 million and asset write-downs and write-offs of $4 million. The impact of these charges was included in "Restructuring and asset related charges - net" in the consolidated statements of income.

At December 31, 2020, $8 million was included in "Accrued and other current liabilities" and $1 million was included in "Other noncurrent obligations" in the consolidated balance sheets.

DowDuPont Cost Synergy Program

In September and November 2017, the Corporation approved restructuring actions that were aligned with DowDuPont's synergy targets. In connection with this program, the Corporation recorded restructuring charges for severance and related benefit costs of $2 million in 2020, $4 million in 2019 and $3 million in 2018. These charges were shown as "Restructuring and asset related charges ‑ net” in the consolidated statements of income. The program was completed in 2020 with cumulative severance payments of $19 million. At December 31, 2019, severance of $16 million had been paid, leaving a liability of $1 million recorded in "Accrued and other current liabilities" in the consolidated balance sheets.

The Corporation 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 Corporation 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.

2019 Asset Related Charges

On August 13, 2019, the Corporation entered into a definitive agreement to sell its acetone derivatives product line to ALTIVIA Ketones & Additives, LLC. As a result of this planned transaction, the Corporation recognized a pretax impairment charge of $75 million in the third quarter of 2019. The impairment charge was included in "Restructuring and asset related charges - net" in the consolidated statements of income. See Notes 5 and 18 for additional information.

In the first quarter of 2018, a settlement was reached for a tax matter regarding fees paid to the Corporation by a foreign nonconsolidated affiliate. As a result, the Corporation recorded an increase of $40 million to "Income taxes receivable" and "Income taxes payable" in the consolidated balance sheets. There was no impact to the consolidated statements of income. In the second quarter of 2018, a payment of $40 million was made for the settlement of the tax matter.

The Corporation is included in TDCC's consolidated federal income tax group and DowDuPont's consolidated tax return through March 31, 2019. Current and deferred tax expenses are calculated for the Corporation as a stand-alone group and are allocated to the group from the consolidated totals, consistent with the TDCC-UCC Tax Sharing Agreement. The Corporation is currently under examination in a number of tax jurisdictions, including the U.S. federal and various state jurisdictions. It is reasonably possible that these examinations may be resolved in the next twelve months. The impact on the Corporation’s results of operations is not expected to be material.

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

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 Corporation's management that the possibility is remote that costs in excess of those accrued will have a material impact on the Corporation's consolidated financial statements.

NOTE 14 - COMMITMENTS AND CONTINGENT LIABILITIES

Environmental Matters

Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies.

At December 31, 2020, the Corporation had accrued obligations of $133 million for probable environmental remediation and restoration costs, including $18 million for the remediation of Superfund sites. These obligations were included in "Accrued and other current liabilities" and "Other noncurrent obligations" in the consolidated balance sheets. This is management's best estimate of the costs for remediation and restoration with respect to environmental matters for which the Corporation has accrued liabilities, although it is reasonably possible that the ultimate cost with respect to these particular matters could range up to approximately two and a half 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 Corporation's results of operations, financial condition and cash flows. It is the opinion of the Corporation's management that the possibility is remote that costs in excess of the range disclosed will have a material impact on the Corporation's results of operations, financial condition and cash flows. Inherent uncertainties exist in these estimates primarily due to unknown environmental conditions, changing governmental regulations and legal standards regarding liability, and emerging remediation technologies for handling site remediation and restoration. As new or additional information becomes available and/or certain spending trends become known, management will evaluate such information in determination of the current estimate of the environmental liability. At December 31, 2019, the Corporation had accrued obligations of $132 million for probable environmental remediation and restoration costs, including $20 million for the remediation of Superfund sites.

The following table summarizes the activity in the Corporation's accrued obligations for environmental matters for the years ended December 31, 2020 and 2019:

The amounts charged to income on a pretax basis related to environmental remediation totaled $49 million in 2020, $93 million in 2019 and $38 million in 2018. Capital expenditures for environmental protection were $5 million in 2020, $11 million in 2019 and $9 million in 2018.

Litigation

Asbestos-Related Matters

Introduction

The Corporation 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 UCC sold in the past, alleged exposure to asbestos-containing products located on UCC’s premises and UCC’s responsibility for asbestos suits filed against a former UCC subsidiary, 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 the Corporation’s products.

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

Estimating the Asbestos-Related Liability

Based on a study completed by Ankura Consulting Group, LLC ("Ankura") in January 2003, the Corporation 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. In subsequent years, the Corporation 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 continued to be appropriate.

In 2016, Ankura completed a study to provide estimates for the undiscounted cost of disposing of pending and future claims against UCC and Amchem through the terminal year of 2049, including a reasonable forecast of future defense and processing costs. Based on the study and the Corporation’s internal review of asbestos claim and resolution activity, the Corporation determined estimating the liability through the terminal year of 2049 was more appropriate due to increased knowledge and data about the costs to resolve claims and diminished volatility in filing rates. The Corporation also determined that estimating and accruing a liability for future asbestos-related defense and processing costs was more appropriate as such costs represent expenditures related to legacy activities that do not contribute to current or future revenue generating activities of the Corporation and is also reflective of the manner in which the Corporation manages its asbestos-related exposure, including careful monitoring of the correlation between defense spending and resolution costs. As a result, in the fourth quarter of 2016, the Corporation recorded a $1,113 million increase in its asbestos-related liability for pending and future claims, including future defense and processing costs. Each October, the Corporation requests Ankura to review its historical asbestos claim and resolution activity through the third quarter of the current year, including asbestos-related defense and processing costs, to determine the appropriateness of updating the most recent study.

In December 2018, Ankura completed a study of the Corporation's historical asbestos claim and resolution activity through September 30, 2018, including asbestos-related defense and processing costs, and provided estimates for the undiscounted cost of disposing of pending and future claims against UCC and Amchem through the terminal year of 2049. Based on the study and the Corporation's internal review process, it was determined that no adjustment to the accrual was required.

In December 2019, Ankura stated that an update of its December 2018 study would not provide a more likely estimate of future events than the estimate reflected in the study and, therefore, the estimate in the study remained applicable. Based on the Corporation's internal review process and Ankura's response, the Corporation determined that no change to the accrual was required. At December 31, 2019, the asbestos-related liability for pending and future claims against UCC and Amchem, including future asbestos-related defense and processing costs, was $1,165 million, and approximately 18 percent of the recorded liability related to pending claims and approximately 82 percent related to future claims.

In December 2020, Ankura completed a study of the Corporation's historical asbestos claim and resolution activity through September 30, 2020, including asbestos-related defense and processing costs, and provided estimates for the undiscounted cost of disposing of pending and future claims against UCC and Amchem through the terminal year of 2049. Based on the study and the Corporation's internal review process, it was determined that no adjustment to the accrual was required. At December 31, 2020, the asbestos-related liability for pending and future claims against UCC and Amchem, including future asbestos-related defense and processing costs, was $1,098 million, and approximately 22 percent of the recorded liability related to pending claims and approximately 78 percent related to future claims.

Table of Contents

Summary

The Corporation's management believes the amounts recorded for the asbestos-related liability, including defense and processing costs, reflect reasonable and probable estimates of the liability based on 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 the Corporation to be higher or lower than those projected or those recorded. Any such event could result in an increase or decrease in the recorded liability.

Because of the uncertainties described above, the Corporation cannot estimate the full range of the cost of resolving pending and future asbestos-related claims facing UCC and Amchem. As a result, it is reasonably possible that an additional cost of disposing of asbestos-related claims, including future defense and processing costs, could have a material impact on the Corporation's results of operations and cash flows for a particular period and on the consolidated financial position.

Other Litigation

The Corporation is also involved in a number of legal proceedings and claims with both private and governmental parties. These cover a wide range of matters, including, but not limited to: product liability; trade regulation; governmental tax and regulatory disputes; health, safety and environmental matters; employment matters; patent infringement; contracts; and commercial litigation. While it is not possible at this time to determine with certainty the ultimate outcome of any of the legal proceedings and claims referred to in this filing, management believes 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, cash flows and financial position of the Corporation.

Purchase Commitments

The Corporation has outstanding purchase commitments and various commitments for take-or-pay or throughput agreements. The Corporation 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, 2020 and 2019.

Asset Retirement Obligations

The Corporation has recognized asset retirement obligations related to capping activities at landfill sites in the United States and for demolition and remediation activities at manufacturing sites in the United States and United Arab Emirates. The aggregate carrying amount of these asset retirement obligations was $17 million at December 31, 2020 ($14 million at December 31, 2019). The Corporation has also recognized conditional asset retirement obligations related to asbestos encapsulation as a result of planned demolition and remediation activities at manufacturing sites in the United States. The aggregate carrying amount of conditional asset retirement obligations was $2 million at December 31, 2020 ($2 million at December 31, 2019). The discount rate used to calculate the Corporation's asset retirement obligations and conditional asset retirement obligations was 0.42 percent at December 31, 2020 (2.12 percent at December 31, 2019). These obligations are included in the consolidated balance sheets as “Accrued and other current liabilities” and "Other noncurrent obligations."

The Corporation has not recognized conditional asset retirement obligations for which a fair value cannot be reasonably estimated in its consolidated financial statements. It is the opinion of management that the possibility is remote that such conditional asset retirement obligations, when estimable, will have a material impact on the Corporation's consolidated financial statements based on current costs.

NOTE 15 - LEASES

Operating lease ROU assets are included in "Operating lease right-of-use assets" and finance lease ROU assets are included in "Net property" in the consolidated balance sheets. With respect to lease liabilities, operating lease liabilities are included in "Operating lease liabilities - current" and "Operating lease liabilities - noncurrent," and finance lease liabilities are included in "Long-term debt due within one year" and "Long-Term Debt" in the consolidated balance sheets.

NOTE 17 - PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

Pension Plans

The Corporation has a defined benefit pension plan that covers substantially all employees in the United States. Benefits are based on length of service and the employee's three highest consecutive years of compensation. Employees hired on or after January 1, 2008, earn benefits that are based on a set percentage of annual pay, plus interest. The Corporation also has a non-qualified supplemental pension plan.

The Corporation's funding policy is to contribute to the plan when pension laws or economics either require or encourage funding. In 2020, UCC contributed $2 million to its pension plans, including contributions to fund benefit payments for its non-qualified supplemental plan. UCC expects to contribute approximately $85 million to its pension plans in 2021.

The weighted-average assumptions used to determine pension plan obligations and net periodic benefit costs are provided below:


Pension Plan Assumptions	Benefit Obligations at Dec 31				Net Periodic Costs for the Year Ended
	2020		2019		2020		2019		2018
Discount rate	2.53	%	3.29	%	3.29	%	4.32	%	3.59	%

Table of Contents

Other Postretirement Benefit Plans

The Corporation provides certain health care and life insurance benefits to retired U.S. employees and survivors. The plan provides health care benefits, including hospital, physicians' services, drug and major medical expense coverage and life insurance benefits. The Corporation and the retiree share the cost of these benefits, with the Corporation portion increasing as the retiree has increased years of credited service, although there is a cap on the Corporation portion. The Corporation has the ability to change these benefits at any time. Employees hired after January 1, 2008, are not covered under this plan.

The Corporation funds most of the cost of these health care and life insurance benefits as incurred. In 2020, UCC did not make any contributions to its other postretirement benefit plan trust. Likewise, UCC does not expect to contribute assets to its other postretirement benefit plan trust in 2021.

The weighted-average assumptions used to determine other postretirement benefit plan obligations and net periodic benefit costs for the plan are provided in the following table:


Other Postretirement Benefit Plan Assumptions	Benefit Obligations at Dec 31				Net Periodic Costs for the Year Ended
	2020		2019		2020		2019		2018
Discount rate	2.34	%	3.17	%	3.17	%	4.23	%	3.51	%
Health care cost trend rate assumed for next year	6.75	%	6.25	%	6.25	%	6.50	%	6.75	%
Rate to which the cost trend rate is assumed to decline (the ultimate health care cost trend rate)	5.00	%	5.00	%	5.00	%	5.00	%	5.00	%
Year that the rate reaches the ultimate health care cost trend rate	2028		2025		2025		2025		2025

Assumptions

The discount rates utilized to measure the pension and other postretirement obligations of the plans were based on the yield on high-quality corporate fixed income investments at the measurement date. Future expected actuarially determined cash flows for the 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 Corporation 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 2018 for purposes of measuring the U.S. pension and other postretirement obligations, based on an evaluation of the mortality experience of its pension plans.

A significant component of the overall increase in the Corporation's benefit obligation for the year ended December 31, 2020 was due to the change in weighted-average discount rates, which decreased from 3.29 percent at December 31, 2019 to 2.53 percent at December 31, 2020. A significant component of the overall increase in the Corporation's benefit obligation for the year ended December 31, 2019 was due to the change in weighted-average discount rates, which decreased from 4.32 percent at December 31, 2018 to 3.29 percent at December 31, 2019.

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 equity and other absolute return strategies. Plan assets totaled $3.1 billion at December 31, 2020 and $3.1 billion at December 31, 2019 and included no directly held common stock of Dow Inc.

The Corporation'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 plan.

The plan is permitted to use derivative instruments for investment purposes, as well as for hedging the underlying asset and liability exposures and rebalancing the asset allocation. The plan uses value-at-risk, stress testing, scenario analysis and Monte Carlo simulation to monitor and manage both the risk within the portfolios and the surplus risk of the plan.

Equity securities primarily include investments in large- and small-cap companies located in both developed and emerging markets around the world. Fixed income securities are primarily U.S. dollar based and include U.S. treasuries and investment grade corporate bonds of companies diversified across industries. Alternative investments primarily include investments in real estate, private equity and absolute return strategies. Other significant investment types include various insurance contracts, and interest rate, equity and foreign exchange derivative investments and hedges.

The Corporation mitigates the credit risk of investments by establishing guidelines with the 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 Corporation and the external managers. Credit risk for hedging activity is mitigated by utilizing multiple counterparties, collateral support agreements, and centralized clearing where appropriate.

A short-term investment money market fund is utilized as the sweep vehicle for the pension plan, which from time to time can represent a significant investment. Approximately 31 percent of the liability of the pension plan is covered by a participating group annuity issued by Prudential Insurance Company.

Table of Contents

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


Target Allocation for Plan Assets at Dec 31, 2020	Target Allocation
Asset Category
Equity securities	23	%
Fixed income securities	45
Alternative investments	27
Other	5
Total	100	%

Fair value calculations may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Corporation 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 assets classified as Level 1 measurements (measured using quoted prices in active markets), the 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 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 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.

Certain pension plan assets are held in funds where fair value is based on an estimated net asset value per share (or its equivalent) as of the most recently available fund financial statements which are received on a monthly or quarterly basis. These valuations are reviewed for reasonableness based on applicable sector, benchmark and company performance. Adjustments to valuations are made where appropriate to arrive at an estimated net asset value per share at the measurement date. These funds are not classified within the fair value hierarchy.

Defined Contribution Plans

In addition to the qualified defined benefit pension plan, U.S. employees may participate in defined contribution plans by contributing a portion of their compensation, which is partially matched by the Corporation. Expense recognized for all defined contribution plans was $7 million in 2020, $9 million in 2019 and $15 million in 2018.

NOTE 18 - FAIR VALUE MEASUREMENTS

The Corporation's financial instruments are classified as Level 2 measurements. 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.

Assets that are measured using significant other observable inputs are primarily valued by reference to quoted prices of similar assets in active markets, adjusted for any terms specific to that asset. For all other 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. There were no transfers between Levels 1 and 2 in the years ended December 31, 2020 and 2019.

The following table summarizes the fair value of the Corporation's financial instruments at December 31, 2020 and 2019:


Fair Value of Financial Instruments	2020								2019

Fair Value Measurements on a Nonrecurring Basis

In 2019, the Corporation recognized an impairment charge of $75 million resulting from the planned divestiture of its acetone derivatives product line to ALTIVIA Ketones & Additives, LLC. The transaction included the Corporation's acetone derivatives related inventory and production assets located in Institute, West Virginia, in addition to the site infrastructure, land and utilities and certain railcars previously owned by TDCC. The assets, classified as Level 3 measurements and valued using unobservable inputs, were written down to zero in 2019, except for inventory and railcars. The impairment charge was included in "Restructuring and asset related charges - net" in the consolidated statements of income. See Note 6 for additional information.

NOTE 19 - RELATED PARTY TRANSACTIONS

Product and Services Agreements

The Corporation sells its products to TDCC to simplify the customer interface process. Products are sold to and purchased from TDCC at prices determined in accordance with the terms of an agreement between UCC and TDCC. After each quarter, the Corporation and TDCC analyze the pricing used for the sales in that quarter and reach agreement on any necessary adjustments, at which point the prices are final. The Corporation also procures certain commodities and raw materials through a TDCC subsidiary and pays a commission to that TDCC subsidiary based on the volume and type of commodities and raw materials purchased.

The Corporation also has a master services agreement with TDCC, whereby TDCC provides services including, but not limited to: accounting; legal; treasury (investments, cash management, risk management, insurance); procurement; human resources; environmental; health and safety; and business management for UCC. Under the master services agreement with TDCC, general administrative and overhead type services that TDCC routinely allocates to various businesses are charged to UCC. The master services agreement cost allocation basis is headcount and includes a 10 percent service fee.

The following table summarizes UCC’s transactions with TDCC and a TDCC subsidiary related to product and services agreements for the years ended December 31, 2020, 2019 and 2018:


Product and Services Agreements Transactions	2020		2019		2018		Income Statement

1.Period end balances on hand are included in inventory. Amounts reported for 2019 and 2018 are approximate, as reported in prior years.

Management believes the method used for determining expenses charged by TDCC is reasonable. TDCC provides these services by leveraging its centralized functional service centers to provide services at a cost that management believes provides an advantage to the Corporation.

The monitoring and execution of risk management policies related to interest rate and foreign currency risks, which are based on TDCC’s risk management philosophy, are provided as a service to UCC.

Tax Sharing Agreement

In accordance with the Tax Sharing Agreement between the Corporation and TDCC, the Corporation makes payments to TDCC to cover the Corporation's estimated federal tax liability; payments were $100 million in 2020, $184 million in 2019 and $220 million in 2018.

Table of Contents

Cash Management

As part of TDCC’s cash management process, UCC is a party to revolving loans with TDCC that have interest rates based on LIBOR (London Interbank Offered Rate) with varying maturities. At December 31, 2020, the Corporation had a note receivable of $1.7 billion ($1.5 billion at December 31, 2019) from TDCC under a revolving loan agreement. The Corporation may draw from this note receivable in support of its daily working capital requirements and, as such, the net effect of cash inflows and outflows under this revolving loan agreement is presented in the consolidated statements of cash flows as an operating activity.

The Corporation also has a separate revolving credit agreement with TDCC that allows the Corporation to borrow or obtain credit enhancements up to an aggregate of $1 billion that matures on December 30, 2021. TDCC may demand repayment with a 30-day written notice to the Corporation, subject to certain restrictions. A related collateral agreement provides for the replacement of certain existing pledged assets, primarily equity interests in various subsidiaries and joint ventures, with cash collateral. At December 31, 2020, $937 million was available under the revolving credit agreement ($937 million at December 31, 2019). The cash collateral was reported as "Noncurrent receivables from related companies" in the consolidated balance sheets.

Dividends and Other Equity Transactions

On a quarterly basis, the Corporation's Board reviews and determines if there will be a dividend distribution to its parent company and sole shareholder, TDCC. The Board takes into consideration the level of earnings and cash flows, among other factors, in determining the amount of the dividend distribution. The Corporation declared and paid cash dividends to TDCC totaling $362 million in 2020, $570 million in 2019, and $553 million in 2018.

In the first quarter of 2019, in anticipation of the business separation activities to align TDCC's specialty products business with DowDuPont, UCC issued a stock dividend to TDCC for 63.4 percent of its ownership in DIHC, a cost method investment, which totaled $401 million. UCC also distributed assets and liabilities aligned with TDCC's specialty products business for an additional dividend to TDCC of $71 million. See Note 3 for additional information.

In the fourth quarter of 2019, in anticipation of the Corporation's sale of its acetone derivatives product line to ALTIVIA Ketones & Additives, LLC, TDCC transferred railcars to UCC valued at $3 million as a capital contribution, which is included in "Additional paid in capital" in the consolidated balance sheets. See Notes 5, 6 and 18 for additional information.

NOTE 20 - BUSINESS AND GEOGRAPHIC REGIONS

TDCC conducts its worldwide operations through principal product groups, and the Corporation's business activities comprise components of TDCC's principal product groups rather than stand-alone operations. The Corporation sells substantially all of its products to TDCC in order to simplify the customer interface process, at prices determined in accordance with the terms of an agreement between UCC and TDCC. Because there are no separate reportable business segments for the Corporation and no detailed business information is provided to a chief operating decision maker regarding the Corporation's stand-alone operations, the Corporation's results are reported as a single operating segment.

Sales are attributed to geographic regions based on customer location; long-lived assets are attributed to geographic regions based on asset location. Sales to external customers and long-lived assets by geographic region were as follows:

None.


ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by the Annual Report on Form 10-K, the Corporation carried out an evaluation, under the supervision and with the participation of the Corporation's Disclosure Committee and the Corporation's management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of the Corporation's disclosure controls and procedures pursuant to Exchange Act Rule 15d - 15(b). Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that the Corporation's disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting

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

Management's Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting. The Corporation's internal control framework and processes are designed to provide reasonable assurance to management and the Board of Directors regarding the reliability of financial reporting and the preparation of the Corporation's consolidated financial statements in accordance with accounting principles generally accepted in the United States of America.

The Corporation's internal control over financial reporting includes those policies and procedures that:

•pertain to the maintenance of records, that in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Corporation;

•provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Corporation are being made only in accordance with authorizations of management and Directors of the Corporation; and

•provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Corporation's assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, any system of internal control over financial reporting can provide only reasonable assurance and may not prevent or detect misstatements.

Management assessed the effectiveness of the Corporation's internal control over financial reporting and concluded that, as of December 31, 2020, such internal control is effective. In making the assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in Internal Control--Integrated Framework (2013).

The Corporation's internal control over financial reporting was not subject to attestation by the Corporation's independent registered public accounting firm, Deloitte & Touche LLP, pursuant to the rules of the Securities and Exchange Commission that permit the Corporation to provide only management's report. Therefore, this annual report does not include an attestation report regarding internal controls over financial reporting from Deloitte & Touche LLP.
