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. (together with TDCC, “Dow”) was formed as a wholly owned subsidiary of DowDuPont to serve as the 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. See Note 19 for additional information. Basis of Presentation As a result of Dow Inc.'s Registration Statement on Form 10 becoming effective on March 12, 2019 with the U.S. Securities and Exchange Commission ("SEC"), Dow Inc. is now required to file a Quarterly Report on Form 10-Q. At March 31, 2019, Dow Inc. and TDCC were separate, wholly owned subsidiaries of DowDuPont. At March 31, 2019, Dow Inc. was a holding company that did not have subsidiaries or operations. As a result, financial statements of Dow Inc. have not been included in this Quarterly Report on Form 10-Q and, unless otherwise indicated, the unaudited interim consolidated financial statements and notes thereto relate to TDCC. 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 future relationship between Dow Inc. and TDCC, the companies are filing a combined report for this Quarterly Report on Form 10-Q. The unaudited interim consolidated financial statements of 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 TDCC's Annual Report on Form 10-K for the year ended December 31, 2018. For the periods presented in the unaudited interim consolidated financial statements, TDCC's common shares were owned solely by DowDuPont. 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. From the Merger date through March 31, 2019, transactions between DowDuPont, TDCC and DuPont and their affiliates were treated as related party transactions. Transactions between TDCC and DuPont primarily consisted of the sale and procurement of certain feedstocks, energy and raw materials that were consumed in each company's manufacturing process. In addition, TDCC and DuPont have tolling arrangements and recognize product sales for agriculture products. See Note 18 for additional information. From the Merger date and through March 31, 2019, TDCC’s business activities were components of DowDuPont’s business operations. TDCC’s business activities, including the assessment of performance and allocation of resources, were reviewed and managed by DowDuPont. Information used by the chief operating decision maker of TDCC related to TDCC in its entirety. Accordingly, there were no separate reportable business segments for TDCC under Accounting Standards Codification ("ASC") Topic 280 “Segment Reporting” and TDCC's business results have been reported in this Quarterly Report on Form 10-Q as a single operating segment.

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. TDCC 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 TDCC 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. Additionally, TDCC's consolidated balance sheet reflects the impact of the adoption of ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)" and the associated ASUs (collectively, "Topic 606") at January 1, 2019, by certain nonconsolidated affiliates of TDCC.

Adoption of Accounting Standards

2019

In the first quarter of 2019, TDCC adopted Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)," and associated ASUs related to Topic 842. See Notes 2 and 11 for additional information. TDCC added a significant accounting policy for leases as a result of the adoption of Topic 842:

Leases

TDCC determines whether a contract contains a lease at contract inception. A contract contains a lease if there is an identified asset and TDCC has the right to control the asset.

Operating lease right-of-use (“ROU”) assets represent TDCC’s right to use an underlying asset for the lease term, and lease liabilities represent TDCC’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. TDCC 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.

TDCC 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 TDCC 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.

Additionally, TDCC's consolidated balance sheet reflects the impact of the adoption of ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)" and the associated ASUs (collectively, "Topic 606") at January 1, 2019, by certain nonconsolidated affiliates of TDCC. See Note 6 for additional information.

2018

In the first quarter of 2018, TDCC adopted Topic 606, ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities" and ASU 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory." The adoption of these ASU's resulted in a net decrease of $68 million to retained earnings and a decrease of $20 million to accumulated other comprehensive loss ("AOCL") in the consolidated statements of equity at January 1, 2018.

Dividends

Effective with the Merger, TDCC no longer has publicly traded common stock. TDCC's common shares are owned solely by DowDuPont. As a result, following the Merger, TDCC’s Board of Directors ("Board") determined dividend distributions to DowDuPont. See Note 18 for additional information.
