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 ("U.S. GAAP") 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, 2018.

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.

The Corporation’s business activities comprise components of TDCC’s global operations rather than stand-alone operations. TDCC conducts its worldwide operations through principal product groups. Because there are no separable 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.

Effective August 31, 2017, pursuant to the merger of equals transaction contemplated by the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017, TDCC and its consolidated subsidiaries and E. I. du Pont de Nemours and Company and its consolidated subsidiaries ("DuPont") each merged with subsidiaries of DowDuPont Inc. ("DowDuPont") and, as a result, TDCC and DuPont became subsidiaries of DowDuPont (the "Merger"). Subsequent to the Merger, TDCC and 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 a holding company for the materials science business. On April 1, 2019, DowDuPont completed the separation of its materials science business and Dow Inc. became the direct parent company of TDCC. UCC will continue to be 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 and DowDuPont, have been reflected as related company transactions in the consolidated financial statements. See Note 13 for additional information.

Adoption of Accounting Standards

In the first quarter of 2019, UCC adopted Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)," and associated ASUs related to Topic 842. See Notes 2 and 9 for additional information. UCC added a significant accounting policy for leases as a result of the adoption of Topic 842:

Leases

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 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 (“IBR”) 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 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.

NOTE 2 - RECENT ACCOUNTING GUIDANCE

Recently Adopted Accounting Guidance

In the first quarter of 2019, the Corporation adopted ASU 2016-02, "Leases (Topic 842)," and associated ASUs related to Topic 842, which requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. The new guidance requires that a lessee recognize assets and liabilities for leases, and recognition, presentation and measurement in the financial statements will depend on its classification as a finance or operating lease. In addition, the new guidance requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. Lessor accounting remains largely unchanged from legacy U.S. GAAP but does contain some targeted improvements to align with revenue recognition guidance Topic 606, "Revenue from Contracts with Customers." The new standard was effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, and early adoption was permitted.

The Corporation adopted Topic 842 using the modified retrospective transition approach, applying the new standard to leases existing at the date of initial adoption. The Corporation elected to apply the transition requirements at the effective date rather than at the beginning of the earliest comparative period presented with a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption, and prior periods were not restated. In addition, the Corporation elected to apply the package of practical expedients permitted under the transition guidance which does not require reassessment of prior conclusions, lease classification and initial direct lease costs. The Corporation did not elect to use the hindsight practical expedient in determining the lease term or assessing impairment of ROU assets. Adoption of the new standard resulted in the recording of lease assets and liabilities of $99 million at January 1, 2019. The difference between the additional lease assets and lease liabilities, net of deferred taxes, was recorded as an adjustment to retained earnings and was not material. The adoption of the new guidance did not have a material impact on the Corporation's consolidated statements of income and had no impact on cash flows. See Note 9 for additional information.

NOTE 3 - MERGER WITH DUPONT AND BUSINESS SEPARATION

On April 1, 2019, DowDuPont completed the separation of its materials science business and Dow Inc. became the direct parent company of TDCC. UCC will continue to be a wholly owned subsidiary of TDCC.

In the first quarter of 2019, in anticipation of the business separations, UCC's assets and liabilities aligned with the 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 Holding 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 4.4 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 the 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.

NOTE 4 - REVENUE

Substantially all of the Corporation's revenues are generated by intercompany sales to TDCC. Products are sold to and purchased from TDCC at market-based prices in accordance with the terms of TDCC’s intercompany pricing policies. For the three months ended March 31, 2019 and 2018, approximately 98 percent of the Corporation's revenue related to sales of product; the remaining 2 percent related to the licensing of patents and technology. 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, and are realized when the associated revenue is recognized under the contract with remaining contract terms that range up to 22 years. The Corporation will have rights to future consideration for revenue recognized when product is delivered to the customer. The balance of contract liabilities was $41 million at March 31, 2019 ($41 million at December 31, 2018) and was included in "Accrued and other current liabilities" and "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 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 parent entity, TDCC, and there are no unique economic factors that affect revenue recognition and cash flows associated with these product sales.

NOTE 5 - RESTRUCTURING AND ASSET RELATED CHARGES - NET

In September and November 2017, the Corporation approved restructuring actions that were aligned with DowDuPont’s synergy targets. For the three months ended March 31, 2019, the Corporation recorded pretax restructuring charges of $1 million for severance and related benefit costs ($1 million for the three months ended March 31, 2018). The impact of these charges was shown as “Restructuring and asset related charges - net” in the consolidated statements of income. These actions are expected to be substantially completed by the end of 2019.

The Corporation recorded pretax restructuring charges of $76 million inception-to-date under the restructuring program, consisting of severance and related benefit costs of $14 million, and $62 million for asset write-downs and write-offs of manufacturing and facility related assets at multiple UCC sites, including a steam unit in Institute, West Virginia. At March 31, 2019, severance of $10 million had been paid, leaving a liability of $4 million.

The Corporation expects to incur additional costs in the future related to restructuring activities, as UCC continually looks for ways to enhance the efficiency and cost effectiveness of its operations. The Corporation 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.

NOTE 8 - 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 March 31, 2019, the Corporation had accrued obligations of $100 million for probable environmental remediation and restoration costs, including $18 million for the remediation of Superfund sites. These obligations are included in "Accrued and other current liabilities" and "Other noncurrent obligations" in the consolidated balance sheets. This is management’s current 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 three times that amount. Consequently, it is reasonably possible that environmental remediation and restoration costs in excess of

12

Union Carbide Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

(Unaudited)

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. In the second quarter of 2019, as a result of the potential culmination of long standing negotiations with regulators and/or agencies, management will perform a comprehensive review of UCC's environmental matters, and believes that it is reasonably possible that the accrued obligation for environmental obligations may increase by up to $50 million as a result of the review. At December 31, 2018, the Corporation had accrued obligations of $94 million for probable environmental remediation and restoration costs, including $16 million for the remediation of Superfund sites.

Litigation

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 regulatory proceedings; health, safety and environmental matters; employment; patents; contracts; taxes; and commercial disputes.

Asbestos-Related Matters

A summary of asbestos-related matters can be found in Note 13 to the Consolidated Financial Statements included in the Corporation's Annual Report on Form 10-K for the year ended December 31, 2018.

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

Since 2003, the Corporation has engaged Ankura Consulting Group, LLC ("Ankura"), a third party actuarial specialist, to review the Corporation's historical asbestos-related claim and resolution activity in order to assist UCC management in estimating the Corporation's asbestos-related liability. Each year, Ankura has reviewed the claim and resolution activity to determine the appropriateness of updating the most recent Ankura study.

Based on the December 2018 Ankura review and the Corporation's own review of the data, the Corporation's total asbestos-related liability through the terminal year of 2049, including asbestos-related defense and processing costs, was $1,260 million at December 31, 2018, and was included in “Asbestos-related liabilities - current” and “Asbestos-related liabilities - noncurrent” in the consolidated balance sheets.

Each quarter, the Corporation reviews 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 all these factors in conjunction with the most recent Ankura study and determines whether a change in the estimate is warranted. Based on the Corporation's review of 2019 activity, it was determined that no adjustment to the accrual was required at March 31, 2019.

The Corporation’s asbestos-related liability for pending and future claims and defense and processing costs was $1,243 million at March 31, 2019, and approximately 17 percent of the recorded liability related to pending claims and approximately 83 percent related to future claims.

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

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.

NOTE 9 - 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.

The Corporation routinely leases sales and administrative offices, product and utility production facilities, warehouses and tanks for product storage, motor vehicles, railcars, computers, office machines and equipment. Some leases contain renewal provisions, purchase options and escalation clauses. The terms for these leased assets vary depending on the lease agreement. These leased assets have remaining lease terms that currently range from 1 to 11 years. The Corporation's lease agreements do not contain any material residual value guarantees or restrictive covenants. See Notes 1 and 2 for additional information on leases.

NOTE 12 - 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/quality checks.

NOTE 13 - RELATED PARTY TRANSACTIONS

The Corporation sells its products to TDCC to simplify the customer interface process. Products are sold to and purchased from TDCC at market-based prices in accordance with the terms of TDCC’s intercompany pricing policies. 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 commission expense is included in "Sundry income (expense) - net" in the consolidated statements of income. Purchases from that TDCC subsidiary were $334 million in the first quarter of 2019 ($433 million in the first quarter of 2018). The decrease in purchase costs in the first quarter of 2019 when compared with the same period last year was due to lower feedstock and energy costs.

The Corporation 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. This agreement resulted in expense of $6 million in the first quarter of 2019 ($7 million in the first quarter of 2018) for general administrative and overhead type services and the 10 percent service fee, included in "Sundry income (expense) - net" in the consolidated statements of income. The remaining activity-based costs were $23 million in the first quarter of 2019 ($22 million in the first quarter of 2018), and were included in "Cost of sales" in the consolidated statements of income.

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.

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 March 31, 2019, the Corporation had a note receivable of $1.4 billion ($1.3 billion at December 31, 2018) 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, 2019. 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, with cash collateral. At March 31, 2019, $949 million was available under the revolving credit agreement ($949 million at December 31, 2018). The cash collateral is reported as “Noncurrent receivables from related companies” in the consolidated balance sheets.

Notes to the Consolidated Financial Statements

(Unaudited)

On a quarterly basis, the Corporation's board of directors 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. In the first quarter of 2019, the Corporation declared and paid a cash dividend of $160 million to TDCC. In the first quarter of 2018, the Corporation declared and paid a cash dividend of $111 million to TDCC.

Also, in the first quarter of 2019, in anticipation of the business separation activities to align the 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 the specialty products business for an additional dividend to TDCC of $71 million. See Note 3 for additional information.

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. Effective August 31, 2017, pursuant to the merger of equals transaction contemplated by the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017, TDCC and E. I. du Pont de Nemours and Company ("DuPont") each merged with subsidiaries of DowDuPont Inc. ("DowDuPont") and, as a result, TDCC and DuPont became subsidiaries of DowDuPont (the "Merger"). Subsequent to the Merger, TDCC and 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 a holding company for the materials science business. On April 1, 2019, DowDuPont completed the separation of its materials science business and Dow Inc. became the direct parent company of TDCC. UCC will continue to be a wholly owned subsidiary of TDCC.

TDCC conducts its worldwide operations through principal product groups. UCC's business activities comprise components of TDCC’s principal product groups rather than stand-alone operations. Because there are no separable 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.

RESULTS OF OPERATIONS

Net Sales

Total net sales were $1,278 million in the first quarter of 2019 compared with $1,318 million in the first quarter of 2018, a decrease of 3 percent. Net sales to related companies, principally to TDCC, and based on market prices for the related products, were $1,250 million in the first quarter of 2019 compared with $1,286 million in the first quarter of 2018, a decrease of 3 percent.

Average selling prices decreased 7 percent in the first quarter of 2019 compared with the same quarter last year. Price decreased primarily in response to lower feedstock and other raw material costs, with price decreases in polyethylene, ethyleneamines, water soluble polymers and glutaraldehydes more than offsetting price increases in glycol ethers, vinyl acetate monomers and oxo alcohols. Volume was up 4 percent in the first quarter of 2019 compared with the first quarter of 2018, as a result of weather-related events on the U.S. Gulf Coast in the first quarter of 2018. Volume increases in ethyleneamines, oxo alcohols, water soluble polymers and vinyl acetate monomers more than offset volume declines in polyethylene.

Cost of Sales

Cost of sales was $950 million in the first quarter of 2019 compared with $1,092 million in the first quarter of 2018, a decrease of 13 percent. Decreases in cost of sales for the period ended March 31, 2019, were driven by decreases in feedstock and other raw material costs and lower planned maintenance turnaround spending when compared with the same period last year.

Research and Development ("R&D"), Selling, General and Administrative ("SG&A") Expenses

R&D expenses were $6 million in the first quarter of 2019, compared with $5 million in the same period last year. SG&A expenses were $2 million in the first quarter of 2019, flat compared with the first quarter of 2018.

Restructuring and Asset Related Charges - Net

In the first quarter of 2019 and 2018, the Corporation recorded a pretax charge of $1 million for additional severance and related benefit costs, aligned with the DowDuPont synergy targets. See Note 5 to the Consolidated Financial Statements for additional information on the Corporation's restructuring activities.

Union Carbide Corporation and Subsidiaries

Sundry Income (Expense) - Net

Sundry income (expense) – net includes a variety of income and expense items such as gains or losses on foreign currency exchange, commissions, charges for management services provided by TDCC, interest income, 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 in the first quarter of 2019 was expense of $12 million compared with expense of $8 million in the same quarter last year. The increase in expense was primarily a result of higher pension and other postretirement benefit plan costs in the first quarter of 2019 compared with the same period last year.

Interest Expense and Amortization of Debt Discount

Interest expense and amortization of debt discount was $7 million in the first quarter of 2019, flat compared with the first quarter of 2018.

Provision for Income Taxes

The Corporation reported a tax provision of $54 million in the first quarter of 2019, which resulted in an effective tax rate of 18.1 percent. This compared with a tax provision of $38 million in the first quarter of 2018, which resulted in an effective tax rate of 18.7 percent.

Net Income Attributable to UCC

The Corporation reported net income of $245 million in the first quarter of 2019 compared with $165 million in the first quarter of 2018.

Capital Expenditures

Capital spending in the first quarter of 2019 was $60 million compared with $44 million in the first quarter of 2018, reflecting increased spending for U.S. Gulf Coast projects and site infrastructure projects.

OTHER MATTERS

Recent Accounting Guidance

See Note 2 to the Consolidated Financial Statements for a summary of recent accounting guidance.

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 in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2018 ("2018 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 in the Corporation’s 2018 10-K. Since December 31, 2018, 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.

21

Union Carbide Corporation and Subsidiaries

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	2019		2018
Claims unresolved at Jan 1	12,780		15,427
Claims filed	1,383		1,932
Claims settled, dismissed or otherwise resolved	(1,569	)	(3,026	)
Claims unresolved at Mar 31	12,594		14,333
Claimants with claims against both UCC and Amchem	(4,509	)	(5,148	)
Individual claimants at Mar 31	8,085		9,185

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 Asbestos-Related Matters in Note 8 to the Consolidated Financial Statements and Part II, Item 1. Legal Proceedings.

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 March 31, 2019.

Dividends

On a quarterly basis, the Corporation's board of directors 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.

In the first quarter of 2019, the Corporation declared and paid a cash dividend of $160 million to TDCC ($111 million in the first quarter of 2018). Also, in the first quarter of 2019, in anticipation of the business separation activities to align the 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 the specialty products business for an additional dividend to TDCC of $71 million. On May 1, 2019, the UCC Board of Directors approved a dividend to TDCC of $178 million, payable on June 28, 2019.

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 last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Corporation's internal control over financial reporting.
