Union Carbide Corporation and Subsidiaries

Throughout this Quarterly Report on Form 10-Q, except as otherwise indicated by the context, the terms "Corporation" or "UCC" as used herein mean Union Carbide Corporation and its subsidiaries.

CAUTIONARY STATEMENT ABOUT 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 include, but are not limited to: sales of UCC's products; UCC's expenses, future revenues and profitability; any global and regional economic impacts of a pandemic or other public health-related risks and events on the Corporation’s business; any sanctions, export restrictions, supply chain disruptions or increased economic uncertainty related to the ongoing conflict between Russia and Ukraine; capital requirements and need for and availability of financing; unexpected barriers in the development of technology, including with respect to UCC’s contemplated capital and operating projects; significant litigation and environmental matters and related contingencies and unexpected expenses; the success of competing technologies that are or may become available; the ability to protect UCC's intellectual property in the United States and abroad; 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; fluctuations in energy and raw material prices; management of process safety and product stewardship; changes in consumer preferences and demand; changes in laws and regulations, political conditions or industry development; global economic and capital markets conditions, such as inflation, market uncertainty, interest and currency exchange rates, and equity and commodity prices; business or supply disruptions; security threats, such as acts of sabotage, terrorism or war, including the ongoing conflict between Russia and Ukraine; weather events and natural disasters; disruptions in the Corporation’s information technology networks and systems; and, since The Dow Chemical Company ("TDCC"), a wholly owned subsidiary of Dow Inc. (together, with TDCC and its consolidated subsidiaries, "Dow"), is the primary customer of UCC, Dow's ability to realize its commitment to carbon neutrality on the contemplated timeframe; the size of the markets for Dow’s products and services and its ability to compete in such markets; Dow's failure to develop and market new products and optimally manage product life cycles; the rate and degree of market acceptance of Dow’s products; and changes in relationships with Dow’s significant customers and suppliers.

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 titled "Risk Factors" contained in Part II, Item 1A of this Quarterly Report on Form 10-Q and in Part I, Item 1A of the Corporation's Annual Report on Form 10-K for the year ended December 31, 2022. 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.

NOTE 1 - CONSOLIDATED FINANCIAL STATEMENTS

Basis of Presentation

The unaudited interim consolidated financial statements of Union Carbide Corporation and its subsidiaries (the "Corporation" or "UCC") were prepared in accordance with accounting principles generally accepted in the United States of America and reflect all adjustments (including normal recurring accruals) which, in the opinion of management, are considered necessary for the fair presentation of the results for the periods presented. These statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2022 ("2022 10-K").

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 operations 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.

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 12 for additional information.

NOTE 2 - RECENT ACCOUNTING GUIDANCE

Recently Adopted Accounting Guidance

In the first quarter of 2023, the Corporation adopted the interim period disclosure requirements of Accounting Standards Update ("ASU") 2022-04, "Liabilities — Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations." The ASU, issued in September 2022, requires disclosures intended to enhance the transparency of supplier finance programs. Specifically, the amendments require buyers in a supplier finance program to disclose sufficient information about the program to allow a user of financial statements to understand the program’s nature, activity during the period, changes from period to period and potential magnitude. The amendments are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, except for disclosure of rollforward information, which is required to be disclosed annually and is effective for fiscal years beginning after December 15, 2023. Early adoption is permitted. The amendments should be applied retrospectively to each period in which a balance sheet is presented, except for disclosure of rollforward information, which should be applied prospectively. The Corporation expects to early adopt the annual requirement to disclose rollforward information prospectively beginning in the 2023 annual financial statements. See Note 6 for disclosures related to the Corporation's supplier finance program.

NOTE 3 - REVENUE

Substantially all of the Corporation's revenue is generated by sales of products 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 sells its products to TDCC to simplify the customer interface process.

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 17 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 $31 million at September 30, 2023 ($33 million at December 31, 2022), of which $2 million ($2 million at December 31, 2022) was included in "Accrued and other current liabilities" and $29 million ($31 million at December 31, 2022) was included in "Other noncurrent obligations" in the consolidated balance sheets.

The Corporation disaggregates its revenue from contracts with customers by type of customer (net sales to related companies and net sales to trade customers) as presented in 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 4 - RESTRUCTURING AND ASSET RELATED CHARGES - NET

2023 Restructuring Program

In the first quarter of 2023, the Corporation initiated restructuring actions to achieve its structural cost improvement initiatives in response to the continued economic impact from the global recessionary environment and to enhance its agility and long-term competitiveness across the economic cycle. The program includes workforce cost reductions and actions to rationalize the Corporation's manufacturing assets, which includes asset write-down and write-off charges. As a result of these actions, the Corporation recorded pretax restructuring charges of $14 million, included in "Restructuring and asset related charges - net" in the consolidated statements of income. The charges consisted of severance and related benefit costs of $12 million and asset write-downs and write-offs of $2 million. These actions are expected to be substantially complete by the end of 2024. The Corporation paid $9 million for severance and related benefit costs through September 30, 2023.

At September 30, 2023, a liability for severance and related benefit costs of $1 million was included in "Accrued and other current liabilities" and $2 million was included in "Other noncurrent obligations" in the consolidated balance sheets.

NOTE 6 - SUPPLIER FINANCE PROGRAM

The Corporation is a party to a supply chain financing (“SCF”) program, facilitated by TDCC, which can be used in the ordinary course of business to extend payment terms with the Corporation's vendors. Under the terms of this program, a vendor can voluntarily enter into an agreement with a participating financial intermediary to sell its receivables due from the Corporation. The vendor receives payment from the financial intermediary, and the Corporation pays the financial intermediary on the terms originally negotiated with the vendor, which generally range from 90 to 120 days. The vendor negotiates the terms of the agreements directly with the financial intermediary and the Corporation is not a party to that agreement. The financial intermediary may allow the participating vendor to utilize TDCC's creditworthiness in establishing credit spreads and associated costs, which may provide the vendor with more favorable terms than they would be able to secure on their own. Neither TDCC nor the Corporation provide guarantees related to the SCF program. At September 30, 2023, the Corporation's outstanding obligations confirmed as valid under the SCF program were $25 million ($29 million at December 31, 2022), included in “Accounts payable – Trade” in the consolidated balance sheets.

NOTE 7 - COMMITMENTS AND CONTINGENCIES

A summary of the Corporation's commitments and contingencies can be found in Note 13 to the Consolidated Financial Statements included in the 2022 10-K, which is incorporated by reference herein.

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 September 30, 2023, the Corporation had accrued obligations of $203 million for probable environmental remediation and restoration costs ($183 million at December 31, 2022), including $37 million for the remediation of Superfund sites ($36 million at December 31, 2022). 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 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.

During the first quarter of 2022, the Corporation recorded a pretax charge of $37 million, included in "Cost of sales" in the consolidated statements of income, related to environmental remediation at a number of current and historical locations. The charge primarily resulted from updated remediation estimates and scope changes on existing matters.

11

Litigation

Asbestos-Related Matters

Each quarter, the Corporation reviews asbestos-related claims filed, settled and dismissed, as well as average settlement and resolution costs by disease category. The Corporation also considers additional 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. UCC management considers these factors in conjunction with the most recent actuarial study and determines whether a change in the estimate is warranted. Based on the Corporation's review of 2023 activity, it was determined that no adjustment to the accrual was required at September 30, 2023.

The Corporation’s total asbestos-related liability for pending and future claims and defense and processing costs was $884 million at September 30, 2023 ($947 million at December 31, 2022), and was included in “Asbestos-related liabilities - current” and “Asbestos-related liabilities - noncurrent” in the consolidated balance sheets. At September 30, 2023, approximately 23 percent of the recorded claim liability related to pending claims and approximately 77 percent related to future claims.

NOTE 8 - LEASES

NOTE 11 - 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.

The following table summarizes the fair value of the Corporation's financial instruments at September 30, 2023 and December 31, 2022:

Fair Value of Financial Instruments	Sep 30, 2023								Dec 31, 2022
In millions	Cost		Gain		Loss		Fair Value		Cost		Gain		Loss		Fair Value
Cash equivalents 1	$	10	$	—	$	—	$	10	$	10	$	—	$	—	$	10
Long-term debt including debt due within one year	$	(263)	$	—	$	(20)	$	(283)	$	(394)	$	—	$	(29)	$	(423)

1.Money market fund is included in "Cash and cash equivalents" in the consolidated balance sheets and held at amortized cost, which approximates fair value.

Cost approximates fair value for all other financial instruments.

Fair Value Measurements on a Nonrecurring Basis

As part of the 2023 Restructuring Program, the Corporation rationalized its manufacturing assets to achieve its structural cost improvement initiatives. In the first quarter of 2023, the manufacturing assets associated with this plan, classified as Level 3 measurements and valued using unobservable inputs, were written down to zero and the Corporation recorded an impairment charge of $2 million, which was included in "Restructuring and asset related charges - net" in the consolidated statements of income.

NOTE 12 - RELATED PARTY TRANSACTIONS

A summary of the Corporation's related party transactions can be found in Note 18 to the Consolidated Financial Statements included in the 2022 10-K.

Product and Services Agreements

The following table summarizes UCC’s transactions with TDCC and a TDCC subsidiary related to product and services agreements for the three and nine months ended September 30, 2023 and 2022:

Product and Services Agreements Transactions	Three Months Ended				Nine Months Ended
	Sep 30, 2023		Sep 30, 2022		Sep 30, 2023		Sep 30, 2022		Income Statement Classification
In millions
TDCC Subsidiary:
Commodity and raw material purchases 1	$	286	$	518	$	867	$	1,586	Cost of sales

Activity-based costs 2	$	23	$	24	$	74	$	66	Cost of sales

1.Period-end balances on hand are included in inventory. The decrease in purchase costs was primarily due to lower feedstock and energy costs and lower production.

2.The year-to-date increase in activity-based costs was primarily due to labor expense for engineering related to capital investment activity on the U.S. Gulf Coast.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Pursuant to General Instruction H(1)(a) and (b) for Form 10-Q "Omission of Information by Certain Wholly-Owned Subsidiaries," the Corporation is filing this Form 10-Q with a reduced disclosure format.

References 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. TDCC has been a wholly owned subsidiary of Dow Inc. since 2019.

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.

Seadrift Operations Unplanned Shutdown

On October 19, 2023, the Corporation’s manufacturing site in Seadrift, Texas, (“Seadrift”) initiated a sequenced site shutdown necessary to repair an underground water leak. Seadrift operations, which primarily produces polyethylene, ethylene oxide, ethylene glycol, glycol ethers and plastics used in wire and cable applications, is expected to be shut down for a minimum of 7 days.

RESULTS OF OPERATIONS

Net Sales

Total net sales were $3,378 million for the first nine months of 2023 compared with $4,385 million for the first nine months of 2022, a decrease of 23 percent. Net sales to related companies, principally to TDCC, were $3,284 million for the first nine months of 2023 compared with $4,228 million for the first nine months of 2022, a decrease of 22 percent. Selling prices to TDCC are determined in accordance with the terms of an agreement between UCC and TDCC.

Average selling price for the first nine months of 2023 decreased 18 percent compared with the first nine months of 2022. Price decreased in almost all product lines in response to lower raw material and feedstock costs. Volume for the first nine months of 2023 decreased 5 percent compared with the first nine months of 2022, with decreases across almost all product lines. Volume decreases were primarily in surfactants, glycol ethers and oxo alcohols, which were negatively impacted by various factors, including reduced demand, internal and external raw material supply limitations, including impacts from the July 2023 explosion and fire at TDCC's Louisiana Operations Glycol-2 unit in Plaquemine, Louisiana, and planned maintenance turnaround activities.

Cost of Sales

Cost of sales was $2,913 million for the first nine months of 2023 compared with $3,687 million for the first nine months of 2022, a decrease of 21 percent. The decrease in cost of sales was driven primarily by lower raw material, feedstock and energy costs on lower volume, partially offset by spending for large planned maintenance turnaround projects at the Corporation's manufacturing site in St. Charles, Louisiana. Cost of sales as a percentage of net sales was 86.2 percent for the first nine months of 2023 compared with 84.1 percent for the first nine months of 2022.

Restructuring and Asset Related Charges - Net

In the first quarter of 2023, the Corporation initiated restructuring actions to achieve its structural cost improvement initiatives in response to the continued economic impact from the global recessionary environment and to enhance

15

its agility and long-term competitiveness across the economic cycle. The program includes workforce cost reductions and actions to rationalize the Corporation's manufacturing assets, which include asset write-down and write-off charges. As a result of these actions, the Corporation recorded pretax restructuring charges of $14 million, included in "Restructuring and asset related charges - net" in the consolidated statements of income. See Note 4 to the Consolidated Financial Statements for additional information about the Corporation's restructuring activities and related charges.

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.

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, non-operating pension and other postretirement benefit plan credits or costs, commissions, gains and losses on sales of investments and assets, losses on early extinguishment of debt and gains and losses on foreign currency exchange.

Sundry income (expense) – net in the first nine months of 2023 was expense of $67 million compared with $40 million in the first nine months of 2022. The increase was primarily the result of lower net non-operating pension and other postretirement benefit plan credits resulting from higher interest cost and lower expected return on assets, partially offset by lower net actuarial loss amortization related to the plans. See Note 10 to the Consolidated Financial Statements for additional information about the Corporation's pension and other postretirement benefit plans.

Interest Income

Interest income was $30 million for the first nine months of 2023 compared with $9 million for the first nine months of 2022. The increase in interest income primarily resulted from the significant increase in the interest rate on the Corporation's note receivable from TDCC since the first quarter of 2022.

Interest Expense and Amortization of Debt Discount

Interest expense and amortization of debt discount was $13 million in the first nine months of 2023 compared with $20 million in the first nine months of 2022, reflecting reduced interest expense resulting from the maturity and payment of long-term debt of $129 million in April 2023.

Provision for Income Taxes

The Corporation is subject primarily to U.S. federal and state taxes. For the first nine months of 2023, the Corporation reported a tax provision of $79 million, which resulted in an effective tax rate of 21.0 percent compared with $144 million for the first nine months of 2022, which resulted in an effective tax rate of 23.3 percent. The tax rate for the first nine months of 2023 was favorably impacted by interest accrued on tax receivables.

Net Income Attributable to UCC

The Corporation reported net income of $298 million for the first nine months of 2023 compared with $475 million for the first nine months of 2022.

Capital Expenditures

Capital expenditures in the first nine months of 2023 were $203 million compared with $91 million in the first nine months of 2022, as the Corporation increased investment in production assets and environmental protection projects, primarily on the U.S. Gulf Coast.

Pension Plans

The Corporation expects to pursue certain de-risking opportunities for its pension plans, including annuitization and risk transfer of certain pension liabilities. If executed, the transactions will result in a non-operating and non-cash settlement charge in the range of $100 million to $200 million in the fourth quarter of 2023. See Note 10 to the Consolidated Financial Statements and Note 16 to the Consolidated Financial Statements included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2022 ("2022 10-K") for additional information related to the Corporation's pension plans.

OTHER MATTERS

Critical Accounting Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America 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 included in the 2022 10-K describes the significant accounting policies and methods used in the preparation of the consolidated financial statements. The Corporation’s critical accounting policies that are impacted by judgments, assumptions and estimates are described in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the 2022 10-K. Since December 31, 2022, there have been no material changes in the Corporation’s accounting policies that are impacted by judgments, assumptions and estimates.

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"). 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	2023	2022
Claims unresolved at Jan 1	6,873	8,747
Claims filed	3,097	3,662
Claims settled, dismissed or otherwise resolved	(3,428)	(5,823)
Claims unresolved at Sep 30	6,542	6,586
Claimants with claims against both UCC and Amchem	(1,452)	(1,502)
Individual claimants at Sep 30	5,090	5,084

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. 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 Asbestos-Related Matters in Note 7 to the Consolidated Financial Statements; Part II, Item 1. Legal Proceedings; and Note 13 to the Consolidated Financial Statements included in the 2022 10-K.

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 September 30, 2023.

Dividends

On a quarterly basis, the Corporation's Board of Directors ("the 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. For

17

the first nine months of 2023, the Corporation declared and paid cash dividends of $394 million to TDCC ($768 million for the first nine months of 2022). On October 18, 2023, the Board approved a dividend to TDCC of $118 million, payable on or before December 29, 2023.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Omitted pursuant to General Instruction H of Form 10-Q.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, 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 paragraph (b) of Exchange Act Rules 13a-15 and 15d-15. 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 and 15d-15 that was conducted during the quarter ended September 30, 2023, that have materially affected, or are reasonably likely to materially affect, the Corporation's internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]

CONSOLIDATED FINANCIAL STATEMENTS

Basis of Presentation

The unaudited interim consolidated financial statements of Union Carbide Corporation and its subsidiaries (the "Corporation" or "UCC") were prepared in accordance with accounting principles generally accepted in the United States of America and reflect all adjustments (including normal recurring accruals) which, in the opinion of management, are considered necessary for the fair presentation of the results for the periods presented. These statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2022 ("2022 10-K").

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 operations 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.

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 12 for additional information.

Accounting Changes and Error Corrections [Abstract]
Accounting Standards Update and Change in Accounting Principle	RECENT ACCOUNTING GUIDANCERecently Adopted Accounting GuidanceIn the first quarter of 2023, the Corporation adopted the interim period disclosure requirements of Accounting Standards Update ("ASU") 2022-04, "Liabilities — Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations." The ASU, issued in September 2022, requires disclosures intended to enhance the transparency of supplier finance programs. Specifically, the amendments require buyers in a supplier finance program to disclose sufficient information about the program to allow a user of financial statements to understand the program’s nature, activity during the period, changes from period to period and potential magnitude. The amendments are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, except for disclosure of rollforward information, which is required to be disclosed annually and is effective for fiscal years beginning after December 15, 2023. Early adoption is permitted. The amendments should be applied retrospectively to each period in which a balance sheet is presented, except for disclosure of rollforward information, which should be applied prospectively. The Corporation expects to early adopt the annual requirement to disclose rollforward information prospectively beginning in the 2023 annual financial statements. See Note 6 for disclosures related to the Corporation's supplier finance program.

Revenue Recognition and Deferred Revenue [Abstract]

Revenue from Contract with Customer [Text Block]

REVENUE

Substantially all of the Corporation's revenue is generated by sales of products 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 sells its products to TDCC to simplify the customer interface process.

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 17 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 $31 million at September 30, 2023 ($33 million at December 31, 2022), of which $2 million ($2 million at December 31, 2022) was included in "Accrued and other current liabilities" and $29 million ($31 million at December 31, 2022) was included in "Other noncurrent obligations" in the consolidated balance sheets.

The Corporation disaggregates its revenue from contracts with customers by type of customer (net sales to related companies and net sales to trade customers) as presented in 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.

RESTRUCTURING AND ASSET RELATED CHARGES - NET

2023 Restructuring Program

In the first quarter of 2023, the Corporation initiated restructuring actions to achieve its structural cost improvement initiatives in response to the continued economic impact from the global recessionary environment and to enhance its agility and long-term competitiveness across the economic cycle. The program includes workforce cost reductions and actions to rationalize the Corporation's manufacturing assets, which includes asset write-down and write-off charges. As a result of these actions, the Corporation recorded pretax restructuring charges of $14 million, included in "Restructuring and asset related charges - net" in the consolidated statements of income. The charges consisted of severance and related benefit costs of $12 million and asset write-downs and write-offs of $2 million. These actions are expected to be substantially complete by the end of 2024. The Corporation paid $9 million for severance and related benefit costs through September 30, 2023.

At September 30, 2023, a liability for severance and related benefit costs of $1 million was included in "Accrued and other current liabilities" and $2 million was included in "Other noncurrent obligations" in the consolidated balance sheets.

Supplier Finance Program	9 Months Ended

Payables and Accruals [Abstract]
Supplier Finance Program	SUPPLIER FINANCE PROGRAMThe Corporation is a party to a supply chain financing (“SCF”) program, facilitated by TDCC, which can be used in the ordinary course of business to extend payment terms with the Corporation's vendors. Under the terms of this program, a vendor can voluntarily enter into an agreement with a participating financial intermediary to sell its receivables due from the Corporation. The vendor receives payment from the financial intermediary, and the Corporation pays the financial intermediary on the terms originally negotiated with the vendor, which generally range from 90 to 120 days. The vendor negotiates the terms of the agreements directly with the financial intermediary and the Corporation is not a party to that agreement. The financial intermediary may allow the participating vendor to utilize TDCC's creditworthiness in establishing credit spreads and associated costs, which may provide the vendor with more favorable terms than they would be able to secure on their own. Neither TDCC nor the Corporation provide guarantees related to the SCF program. At September 30, 2023, the Corporation's outstanding obligations confirmed as valid under the SCF program were $25 million ($29 million at December 31, 2022), included in “Accounts payable – Trade” in the consolidated balance sheets.

COMMITMENTS AND CONTINGENCIES

A summary of the Corporation's commitments and contingencies can be found in Note 13 to the Consolidated Financial Statements included in the 2022 10-K, which is incorporated by reference herein.

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 September 30, 2023, the Corporation had accrued obligations of $203 million for probable environmental remediation and restoration costs ($183 million at December 31, 2022), including $37 million for the remediation of Superfund sites ($36 million at December 31, 2022). 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 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.

During the first quarter of 2022, the Corporation recorded a pretax charge of $37 million, included in "Cost of sales" in the consolidated statements of income, related to environmental remediation at a number of current and historical locations. The charge primarily resulted from updated remediation estimates and scope changes on existing matters.

Litigation

Asbestos-Related Matters

Each quarter, the Corporation reviews asbestos-related claims filed, settled and dismissed, as well as average settlement and resolution costs by disease category. The Corporation also considers additional 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. UCC management considers these factors in conjunction with the most recent actuarial study and determines whether a change in the estimate is warranted. Based on the Corporation's review of 2023 activity, it was determined that no adjustment to the accrual was required at September 30, 2023.

The Corporation’s total asbestos-related liability for pending and future claims and defense and processing costs was $884 million at September 30, 2023 ($947 million at December 31, 2022), and was included in “Asbestos-related liabilities - current” and “Asbestos-related liabilities - noncurrent” in the consolidated balance sheets. At September 30, 2023, approximately 23 percent of the recorded claim liability related to pending claims and approximately 77 percent related to future claims.

Fair Value Disclosures [Abstract]

Financial Instruments Disclosure [Text Block]

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.

The following table summarizes the fair value of the Corporation's financial instruments at September 30, 2023 and December 31, 2022:

Fair Value of Financial Instruments	Sep 30, 2023								Dec 31, 2022

1.Money market fund is included in "Cash and cash equivalents" in the consolidated balance sheets and held at amortized cost, which approximates fair value.

Cost approximates fair value for all other financial instruments.

Fair Value Measurements on a Nonrecurring Basis

As part of the 2023 Restructuring Program, the Corporation rationalized its manufacturing assets to achieve its structural cost improvement initiatives. In the first quarter of 2023, the manufacturing assets associated with this plan, classified as Level 3 measurements and valued using unobservable inputs, were written down to zero and the Corporation recorded an impairment charge of $2 million, which was included in "Restructuring and asset related charges - net" in the consolidated statements of income.
