CONSOLIDATED FINANCIAL STATEMEN

CONSOLIDATED FINANCIAL STATEMENTS	6 Months Ended
	Jun. 30, 2020
Organization, Consolidation and Presentation of Financial Statements [Abstract]
CONSOLIDATED FINANCIAL STATEMENTS	CONSOLIDATED FINANCIAL STATEMENTS Merger and Separation On April 1, 2019, DowDuPont Inc. (“DowDuPont” and effective June 3, 2019, n/k/a DuPont de Nemours, Inc. or "DuPont") completed the separation of its materials science business and Dow Inc. became the direct parent company of The Dow Chemical Company and its consolidated subsidiaries (“TDCC” and together with Dow Inc., “Dow” or the “Company”). 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. Dow Inc. was formed as a wholly owned subsidiary of DowDuPont to serve as the holding company for the materials science business. See Note 3 for additional information. Basis of Presentation The unaudited interim consolidated financial statements of Dow Inc. and TDCC 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 combined Dow Inc. and TDCC Annual Report on Form 10-K for the year ended December 31, 2019. Effective April 1, 2019, Dow Inc. owns all of the outstanding common shares of TDCC. TDCC is deemed the predecessor to Dow Inc. and the historical results of TDCC are deemed the historical results of Dow Inc. for periods prior to and including March 31, 2019. As a result of the parent/subsidiary relationship between Dow Inc. and TDCC, and considering that the financial statements and disclosures of each company are substantially similar, the companies are filing a combined report for this Quarterly Report on Form 10-Q. The information reflected in the report is equally applicable to both Dow Inc. and TDCC, except where otherwise noted. As of the effective date and time of the distribution, DowDuPont does not beneficially own any equity interest in Dow and no longer consolidates Dow and its consolidated subsidiaries into its financial results. The consolidated financial results of Dow for all periods presented reflect the distribution of TDCC’s agricultural sciences business (“AgCo”) and specialty products business (“SpecCo”) as discontinued operations, as well as the receipt of Historical DuPont’s ethylene and ethylene copolymers businesses (other than its ethylene acrylic elastomers business) (“ECP”) as a common control transaction from the closing of the Merger on August 31, 2017. See Note 3 for additional information. From the Merger date through the separation, transactions between DowDuPont, TDCC and Historical DuPont and their affiliates were treated as related party transactions. Transactions between TDCC and Historical DuPont primarily consisted of the sale and procurement of certain raw materials that were consumed in each company's manufacturing process. Transactions between TDCC and Dow Inc. are treated as related party transactions for TDCC. See Note 21 for additional information. Throughout this Quarterly Report on Form 10-Q, unless otherwise indicated, amounts and activity are presented on a continuing operations basis. Except as otherwise indicated by the context, the term "Union Carbide" means Union Carbide Corporation and "Dow Silicones" means Dow Silicones Corporation, both wholly owned subsidiaries of the Company. Adoption of Accounting Standards In the first quarter of 2019, the Company adopted Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)", and the associated ASUs (collectively, "Topic 842"). The net impact to “Retained earnings” was an increase of $72 million and was primarily a result of the recognition of a deferred gain associated with a prior sale-leaseback transaction. See Note 13 for additional information. Additionally, at January 1, 2019, certain nonconsolidated affiliates of the Company, which were subsequently distributed as part of the separation from DowDuPont, adopted ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)" and the associated ASUs (collectively, "Topic 606"). The net impact to "Retained earnings" was a reduction of $183 million at January 1, 2019.

COMMITMENTS AND CONTINGENT LIABILITIES	6 Months Ended
	Jun. 30, 2020
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure	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 June 30, 2020, the Company had accrued obligations of $1,118 million for probable environmental remediation and restoration costs, including $205 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 best estimate of the costs for remediation and restoration with respect to environmental matters for which the Company has accrued liabilities, although it is reasonably possible that the ultimate cost with respect to these particular matters could range up to approximately two times that amount. Consequently, it is reasonably possible that environmental remediation and restoration costs in excess of amounts accrued could have a material impact on the Company's results of operations, financial condition and cash flows. It is the opinion of the Company’s management, however, that the possibility is remote that costs in excess of the range disclosed will have a material impact on the Company’s results of operations, financial condition and cash flows. Inherent uncertainties exist in these estimates primarily due to unknown conditions, changing governmental regulations and legal standards regarding liability, and emerging remediation technologies for handling site remediation and restoration. 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 environmental liability. At December 31, 2019, the Company had accrued obligations of $1,155 million for probable environmental remediation and restoration costs, including $207 million for the remediation of Superfund sites. Litigation Asbestos-Related Matters of Union Carbide Corporation A summary of Asbestos-Related Matters of Union Carbide Corporation can be found in Note 17 to the Consolidated Financial Statements included in the combined Dow Inc. and TDCC Annual Report on Form 10-K for the year ended December 31, 2019. Introduction Union Carbide is and has been involved in a large number of asbestos-related suits filed primarily in state courts during the past four decades. These suits principally allege personal injury resulting from exposure to asbestos-containing products and frequently seek both actual and punitive damages. The alleged claims primarily relate to products that Union Carbide sold in the past, alleged exposure to asbestos-containing products located on Union Carbide’s premises and Union Carbide’s responsibility for asbestos suits filed against a former Union Carbide subsidiary, Amchem Products, Inc. (“Amchem”). In many cases, plaintiffs are unable to demonstrate that they have suffered any compensable loss as a result of such exposure, or that injuries incurred in fact resulted from exposure to Union Carbide’s products. Union Carbide expects more asbestos-related suits to be filed against Union Carbide and Amchem in the future, and will aggressively defend or reasonably resolve, as appropriate, both pending and future claims. Estimating the Asbestos-Related Liability Since 2003, Union Carbide has engaged Ankura Consulting Group, LLC ("Ankura"), a third party actuarial specialist, to review Union Carbide's historical asbestos-related claim and resolution activity in order to assist Union Carbide's management in estimating the asbestos-related liability. Each year, Union Carbide requests Ankura to review its claim and resolution activity, including asbestos-related defense and processing costs, to determine the appropriateness of updating the most recent Ankura study. Based on the review completed by Ankura in December 2019 and Union Carbide's internal review process, Union Carbide's total asbestos-related liability through the terminal year of 2049, including asbestos-related defense and processing costs, was $1,165 million at December 31, 2019, and was included in “Accrued and other current liabilities” and “Asbestos-related liabilities - noncurrent” in the consolidated balance sheets. Each quarter, Union Carbide reviews claims filed, settled and dismissed, as well as average settlement and resolution costs by disease category. Union Carbide also considers additional quantitative and qualitative factors such as the nature of pending claims, trial experience of Union Carbide 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. Union Carbide's management considers these factors in conjunction with the most recent Ankura study and determines whether a change in the estimate is warranted. Based on Union Carbide's review of 2020 activity, it was determined that no adjustment to the accrual was required at June 30, 2020. Union Carbide’s total asbestos-related liability for pending and future claims and defense and processing costs was $1,133 million at June 30, 2020, and approximately 20 percent of the recorded claim liability related to pending claims and approximately 80 percent related to future claims. Summary The Company's management believes the amounts recorded by Union Carbide for the asbestos-related liability, including defense and processing costs, reflect reasonable and probable estimates of the liability based upon current, known facts. However, future events, such as the number of new claims to be filed and/or received each year, the average cost of defending and disposing of each such claim, as well as the numerous uncertainties surrounding asbestos litigation in the United States over a significant period of time, could cause the actual costs for Union Carbide to be higher or lower than those projected or those recorded. Any such events could result in an increase or decrease in the recorded liability. Because of the uncertainties described above, Union Carbide cannot estimate the full range of the cost of resolving pending and future asbestos-related claims facing Union Carbide and Amchem. As a result, it is reasonably possible that an additional cost of disposing of Union Carbide's asbestos-related claims, including future defense and processing costs, could have a material impact on the Company's results of operations and cash flows for a particular period and on the consolidated financial position. Dow Silicones Chapter 11 Related Matters A summary of the Dow Silicones Chapter 11 Related Matters can be found in Note 17 to the Consolidated Financial Statements included in the combined Dow Inc. and TDCC Annual Report on Form 10-K for the year ended December 31, 2019. Introduction In 1995, Dow Silicones, then a 50:50 joint venture between the Company and Corning Incorporated ("Corning"), voluntarily filed for protection under Chapter 11 of the U.S. Bankruptcy Code in order to resolve Dow Silicones’ breast implant liabilities and related matters (the “Chapter 11 Proceeding”). Dow Silicones emerged from the Chapter 11 Proceeding on June 1, 2004 and is implementing the Joint Plan of Reorganization (the “Plan”). The Plan provides funding for the resolution of breast implant and other product liability litigation covered by the Chapter 11 Proceeding and provided a process for the satisfaction of commercial creditor claims in the Chapter 11 Proceeding. As of June 1, 2016, Dow Silicones is a wholly owned subsidiary of the Company. Breast Implant and Other Product Liability Claims Under the Plan, a product liability settlement program administered by an independent claims office (the “Settlement Facility”) was created to resolve breast implant and other product liability claims. Dow Silicones has an obligation to fund the Settlement Facility and is expected to make further contributions after the Settlement Facility's existing funds are exhausted. At June 30, 2020, Dow Silicones and its insurers have made life-to-date payments of $1,762 million to the Settlement Facility and the Settlement Facility reported an unexpended balance of $69 million. The claim filing deadline passed in June 2019. All claims have been received by the Settlement Facility and are being processed. Based on the claims filed at and before the deadline, Dow Silicones estimates that it will be obligated to contribute an additional $160 million after the Settlement Facility balance is exhausted. The estimate was updated in the second quarter of 2020 with the assistance of a third party consultant, and the change in estimate primarily reflects decreased administrative costs compared with the previous estimate and an increase in investment income resulting from insurance proceeds. Dow Silicones' liability for breast implant and other product liability claims ("Implant Liability") was $160 million at June 30, 2020 ($165 million at December 31, 2019), of which zero ($20 million at December 31, 2019) was included in “Accrued and other current liabilities” and $160 million ($145 million at December 31, 2019) was included in "Other noncurrent obligations" in the consolidated balance sheets. Dow Silicones is not aware of circumstances that would change the factors used in estimating the Implant Liability and believes the recorded liability reflects the best estimate of the remaining funding obligations under the Plan; however, the estimate relies upon a number of significant assumptions, including: future acceptance rates, disease mix, and payment values will be materially consistent with historical experience; no material negative outcomes in future controversies or disputes over Plan interpretation will occur; and the Plan will not be modified. If actual outcomes related to any of these assumptions prove to be materially different, the future liability to fund the Plan may be materially different than the amount estimated. Summary The amounts recorded by Dow Silicones for the Chapter 11 related matters described above were based on current, known facts, which management believes reflect reasonable and probable estimates of the liability. However, future events could cause the actual costs for Dow Silicones to be higher or lower than those projected or those recorded. Any such events could result in an increase or decrease in the recorded liability. Other Litigation Matters In addition to the specific matters described above, the Company is party to a number of other claims and lawsuits arising out of the normal course of business with respect to product liability, patent infringement, employment matters, governmental tax and regulation disputes, contract and commercial litigation, and other actions. Certain of these actions purport to be class actions and seek damages in very large amounts. All such claims are being contested. The Company has an active risk management program consisting of numerous insurance policies secured from many carriers at various times. These policies may provide coverage that could be utilized to minimize the financial impact, if any, of certain contingencies described above. It is the opinion of the Company’s management that the possibility is remote that the aggregate of all such other claims and lawsuits will have a material adverse impact on the results of operations, financial condition and cash flows of the Company. Indemnifications with Corning In connection with the June 1, 2016 ownership restructure of Dow Silicones, the Company is indemnified by Corning for at least 50 percent of future losses associated with certain pre-closing liabilities, including the Implant Liability and certain environmental matters described in the preceding sections, subject to certain conditions and limits. The maximum amount of indemnified losses which may be recovered are subject to a cap that declines over time. The Company had indemnification assets of $100 million at June 30, 2020 ($100 million at December 31, 2019), of which $37 million ($37 million at December 31, 2019) was included in "Other current assets" and $63 million ($63 million at December 31, 2019) was included in "Noncurrent receivables" in the consolidated balance sheets. For additional information, see Note 17 to the Consolidated Financial Statements included in the combined Dow Inc. and TDCC Annual Report on Form 10-K for the year ended December 31, 2019. Gain Contingency - Dow v. Nova Chemicals Corporation Patent Infringement Matter On December 9, 2010, Dow filed suit in the Federal Court in Ontario, Canada ("Federal Court") alleging that Nova was infringing the Company's Canadian polyethylene patent 2,106,705. Nova counterclaimed on the grounds of invalidity and non-infringement. On June 29, 2017, the Federal Court issued a Confidential Supplemental Judgment, concluding that Nova must pay $645 million Canadian dollars (equivalent to $495 million U.S. dollars) to the Company, plus pre- and post-judgment interest, for which the Company received payment of $501 million from Nova on July 6, 2017. Although Nova is appealing portions of the damages judgment, certain portions of it are indisputable and will be owed to the Company regardless of the outcome of any further appeals by Nova. At June 30, 2020, the Company had $341 million ($341 million at December 31, 2019) included in "Other noncurrent obligations" in the consolidated balance sheets related to the disputed portion of the damages judgment. The Company is confident of its chances of defending the entire judgment on appeal, particularly the trial court's determinations on important factual issues, which will be accorded deferential review on appeal. For additional information, see Note 17 to the Consolidated Financial Statements included in the combined Dow Inc. and TDCC Annual Report on Form 10-K for the year ended December 31, 2019. Gain Contingency - Dow v. Nova Chemicals Corporation Ethylene Asset Matter On September 18, 2019, the Court of the Queen’s Bench in Alberta, Canada ("Court"), signed a judgment ordering Nova to pay the Company $1.43 billion Canad ian dollars (equivalent to approximately $1.08 billion U.S. dollars) by October 11, 2019, for damages the Company incurred through 2012 related to the companies’ jointly-owned ethylene asset in Joffre, Alberta, Canada. The Court, which initially ruled in June 2018, found that Nova failed to operate the ethylene asset at full capacity for more than ten years, and furthermore, that Nova violated several contractual agreements related to the Company receiving its share of the asset’s ethylene production. These actions resulted in reduced productivity and sales for the Company. Nova has appealed the judgment, however, certain portions of it are not in dispute and are owed to the Company regardless of the outcome of Nova's appeal. In October 2019, Nova paid $1.08 billion Canadian dollars (equivalent to approximately $0.8 billion U.S. dollars) directly to the Company, and remitted $347 million Canadian dollars to the Canada Revenue Agency ("CRA") for the tax account of one of the Company's subsidiaries. The Company sought a refund of the entire amount remitted to the CRA. On March 31, 2020, the Company received the full refund from CRA, equivalent to $259 million U.S. dollars. In preparation for the June 2020 appellate hearing on the case, Nova provided the Court an updated schedule of the financial impact of the issues on appeal, which explained that even if Nova prevails on all appeal issues, the Company would still be entitled to retain an amount in excess of the gain recognized in 2019. As a result, the Company recorded an $18 million pretax gain in the second quarter of 2020, of which $12 million was included in "Selling, general and administrative expenses" and $6 million was included in "Sundry income (expense) - net" in the consolidated statements of income and related to the Packaging & Specialty Plastics segment. At June 30, 2020, $875 million ($893 million at December 31, 2019) was included in "Other noncurrent obligations" in the Company's consolidated balance s heets related to the disputed portion of the damages judgment. Dow remains confident of its chances of defending the entire judgment on appeal, particularly the trial court's determinations on important factual and discretionary issues, which will be accorded deferential review on appeal. Guarantees The following table provides a summary of the final expiration, maximum future payments and recorded liability reflected in the consolidated balance sheets for guarantees: Guarantees Jun 30, 2020 Dec 31, 2019 In millions Final Maximum Recorded Liability Final Maximum Recorded Liability Guarantees 2023 $ 3,788 $ 7 2023 $ 3,952 $ 10 Guarantees arise during the ordinary course of business from relationships with customers, committed accounts receivable facilities and nonconsolidated affiliates when the Company undertakes an obligation to guarantee the performance of others (via delivery of cash or other assets) if specified triggering events occur. With guarantees, such as commercial or financial contracts, non-performance by the guaranteed party triggers the obligation of the Company to make payments to the beneficiary of the guarantee. The majority of the Company’s guarantees relate to debt of nonconsolidated affiliates, which have expiration dates ranging from less than one year to less than three years. The Company’s current expectation is that future payment or performance related to the non-performance of others is considered remote. The Company has entered into guarantee agreements ("Guarantees") related to project financing for Sadara. The total of an Islamic bond and additional project financing (collectively “Total Project Financing”) obtained by Sadara is approximately $12.5 billion. Sadara had $10.4 billion of Total Project Financing outstanding at June 30, 2020 ($10.8 billion at December 31, 2019). The Company's guaran tee of the Total Project Financing is in proportion to the Company's 35 percent ownership interest in Sadara, or up to approximately $3.8 billion when the project financing is fully drawn. Sadara successfully completed an extensive operational testing program in December 2018, however, the Guarantees will be released upon the satisfactory fulfillment of certain project completion conditions, which could occur in the third quarter of 2020, and must occur no later than December 2020. In the first quarter of 2020, Sadara signed its final logistics service agreement, the final substantive step to project completion.

RECENT ACCOUNTING GUIDANCE

RECENT ACCOUNTING GUIDANCE	6 Months Ended

Accounting Changes and Error Corrections [Abstract]
RECENT ACCOUNTING GUIDANCE	RECENT ACCOUNTING GUIDANCE Recently Adopted Accounting Guidance In the first quarter of 2020, the Company adopted ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement," which is part of the Financial Accounting Standards Board's ("FASB") disclosure framework project to improve the effectiveness of disclosures in the notes to the financial statements. The amendments in the new guidance remove, modify and add certain disclosure requirements related to fair value measurements covered in Topic 820, "Fair Value Measurement." The adoption of this guidance did not have a material impact on the consolidated financial statements. See Note 19 for additional information. In the first quarter of 2020, the Company adopted ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract," which requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in Topic 350, "Intangibles - Goodwill and Other" to determine which implementation costs to capitalize as assets or expense as incurred. The adoption of this guidance did not have a material impact on the consolidated financial statements. In the first quarter of 2020, the Company adopted ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" and the associated ASUs (collectively “Topic 326”). The amendments replace the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Accordingly, companies are required to consider forward-looking information to estimate credit losses expected to occur over the estimated life of an asset, including losses that may be incurred in future periods. The adoption of this guidance did not have a material impact on the consolidated financial statements. Accounting Guidance Issued But Not Adopted at June 30, 2020 In December 2019, the FASB 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.

Discontinued Operations and Disposal Groups [Abstract]
Separation from DowDuPont [Text Block]	SEPARATION FROM DOWDUPONT On April 1, 2019, DowDuPont completed the previously announced separation of its materials science business. The separation was effected by way of a pro rata distribution of all of the then-issued and outstanding shares of Dow Inc. common stock to DowDuPont stockholders of record as of the close of business, Eastern Time, on March 21, 2019 (the “Record Date”). The shareholders of record of DowDuPont received one share of Dow Inc. common stock, par value $0.01 per share, for every three shares of DowDuPont common stock, par value $0.01 per share, held as of the Record Date ("Distribution Ratio"). No fractional shares of Dow Inc. common stock were issued. Instead, cash in lieu of any fractional shares was paid to DowDuPont registered shareholders. The number of shares of Dow Inc. common stock issued on April 1, 2019 was 748.8 million shares. On April 1, 2019, Dow Inc. received a cash contribution of $2,024 million from DowDuPont as part of the internal reorganization and business realignment steps between Dow Inc., TDCC and DowDuPont. Dow Inc. recognized a reduction to "Retained earnings" of $14,846 million in the second quarter of 2019 ($14,811 million in the six months ended June 30, 2019) as a result of the cash contribution, the distribution of AgCo and SpecCo, and other separation related adjustments. TDCC recognized a reduction to "Retained earnings" of $16,025 million in the second quarter of 2019 ($15,990 million in the six months ended June 30, 2019) as a result of the distribution of AgCo and SpecCo. Receipt of ECP As the receipt of ECP was accounted for as a transfer between entities under common control, the consolidated financial statements have been retrospectively adjusted to reflect the receipt of ECP from the closing of the Merger on August 31, 2017. All intercompany transactions have been eliminated in consolidation. The ECP assets received and liabilities assumed were recorded at DowDuPont's historical cost basis. Distribution of AgCo and SpecCo Upon distribution, the Company retrospectively adjusted the previously issued consolidated financial statements and presented AgCo and SpecCo as discontinued operations based on the guidance in Accounting Standards Codification (“ASC”) 205-20 “Discontinued Operations.” The results of operations of AgCo and SpecCo are presented as discontinued operations in the consolidated statements of income and are summarized in the table that follows: Results of Operations of AgCo and SpecCo Six Months Ended Jun 30, 2019 In millions Net sales $ 2,953 Cost of sales 1,804 Research and development expenses 175 Selling, general and administrative expenses 262 Amortization of intangibles 61 Restructuring and asset related charges - net 78 Equity in earnings of nonconsolidated affiliates 28 Sundry income (expense) - net (18) Interest income 3 Interest expense and amortization of debt discount 7 Income from discontinued operations before income taxes $ 579 Provision for income taxes 134 Income from discontinued operations, net of tax $ 445 Agreements Related to the Separation and Distribution In connection with the separation, Dow Inc. entered into certain agreements with DuPont and/or Corteva Inc. ("Corteva"), including the following: Separation and Distribution Agreement, Tax Matters Agreement and Employee Matters Agreement (collectively, the "Agreements"). In addition to establishing the terms of the separation, the Agreements provide a framework for Dow’s interaction with DuPont and Corteva after the separation and also provide for the allocation among Dow, DuPont and Corteva of assets, liabilities and obligations attributable to periods prior to, at and after the completion of the separation. The Agreements also contain certain indemnity and/or cross-indemnity provisions that are intended to set forth each party’s respective rights, responsibilities and obligations for matters subject to indemnification. Except in certain instances, the parties’ indemnification obligations are uncapped. Certain indemnification obligations will be subject to reduction by insurance proceeds or other third-party proceeds of the indemnified party that reduces the amount of the loss. In addition, indemnifiable losses will be subject to, in certain cases, “de minimis” threshold amounts and, in certain cases, deductible amounts. The impacts of indemnifications and other post-separation matters relating to the Agreements were primarily reflected in the consolidated financial statements of Dow Inc. In the second quarter of 2019, the Company recorded pretax charges related to the Agreements of $24 million in "Integration and separation costs" and $52 million in "Sundry income (expense) - net" in the consolidated statements of income of Dow Inc. and related to the Corporate segment. At June 30, 2020, the Company had assets of $48 million ($58 million at December 31, 2019) included in "Other current assets" and $32 million ($52 million at December 31, 2019) included in "Noncurrent receivables," and liabilities of $321 million ($352 million at December 31, 2019) included in "Accrued and other current liabilities" and $99 million ($96 million at December 31, 2019) included in "Other noncurrent obligations" in the consolidated balance sheets of Dow Inc. related to the Agreements. Any adjustments to these assets and liabilities in subsequent periods will be recorded in Dow Inc.'s results of operations. In addition, the Company deferred approximately $400 million of the cash distribution received from DowDuPont at separation and recorded an associated liability in "Other noncurrent obligations," with an offset to "Retained earnings" in the consolidated balance sheets of Dow Inc. At June 30, 2020, $130 million ($130 million at December 31, 2019) of this liability was recorded in "Accrued and other current liabilities" and $270 million ($270 million at December 31, 2019) was recorded in "Other noncurrent obligations" in the consolidated balance sheets. The final resolution of this liability is uncertain and any subsequent adjustments to the carrying value of this liability will be reflected in equity of Dow Inc. Integration and Separation Costs Integration and separation costs, which reflect costs related to business separation activities, were $46 million for Dow Inc. and TDCC in the second quarter of 2020, compared with $348 million and $324 million for Dow Inc. and TDCC, respectively, in the second quarter of 2019. Integration and separation costs were $111 million for Dow Inc. and TDCC in the first six months of 2020, compared with $800 million and $776 million for Dow Inc. and TDCC, respectively, in the first six months of 2019.

Segment Reporting [Abstract]
Segments and Geographic Regions [Text Block]	SEGMENTS AND GEOGRAPHIC REGIONSDow’s measure of profit/loss for segment reporting purposes is Operating EBIT (for the three months ended June 30, 2020 and 2019 and the six months ended June 30, 2020) and pro forma Operating EBIT (for the six months ended June 30, 2019) as this is the manner in which the Company's chief operating decision maker ("CODM") assesses performance and allocates resources. The Company defines Operating EBIT as earnings (i.e., "Income (loss) from continuing operations before income taxes") before interest, excluding the impact of significant items. The Company defines pro forma Operating EBIT as earnings (i.e., "Income (loss) from continuing operations before income taxes") before interest, plus pro forma adjustments, excluding the impact of significant items. Operating EBIT and pro forma Operating EBIT by segment include all operating items relating to the businesses; items that principally apply to Dow as a whole are assigned to Corporate. The Company also presents pro forma net sales for the six months ended June 30, 2019 in this footnote as it is included in management's measure of segment performance and is regularly reviewed by the CODM. Pro forma net sales includes the impact of various manufacturing, supply and service related agreements entered into with DuPont and Corteva in connection with the separation which provide for different pricing than the historical intercompany and intracompany pricing practices of TDCC and Historical DuPont.
