Basis of Presentation [Abstract] |
Basis of Accounting, Policy [Policy Text Block] | Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared by Eastman Chemical Company ("Eastman" or the "Company") in accordance and consistent with the accounting policies stated in the Company's 2020 Annual Report on Form 10-K, and should be read in conjunction with the consolidated financial statements in Part II, Item 8 of that report, with the exception of recently adopted accounting standards noted below. The December 31, 2020 financial position data included herein was derived from the consolidated financial statements included in the 2020 Annual Report on Form 10-K but does not include all disclosures required by accounting principles generally accepted in the United States ("GAAP"). In the opinion of management, the unaudited consolidated financial statements include all normal recurring adjustments necessary for fair statement of the interim financial information in conformity with GAAP. These statements contain some amounts that are based upon management estimates and judgments. Future actual results could differ from such current estimates. The unaudited consolidated financial statements include assets, liabilities, sales revenue, and expenses of all majority-owned subsidiaries and joint ventures in which a controlling interest is maintained. Eastman accounts for other joint ventures and investments where it exercises significant influence on the equity basis. Intercompany transactions and balances are eliminated in consolidation. Certain prior period data has been reclassified in the unaudited consolidated financial statements and accompanying footnotes to conform to current period presentation.
New Accounting Pronouncements, Policy [Policy Text Block] | Recently Adopted Accounting Standards Accounting Standards Update ("ASU") ASU 2019-12 Income Taxes - Simplifying the Accounting for Income Taxes: On January 1, 2021, Eastman adopted this update which is a part of the Financial Accounting Standards Board's ("FASB") initiative to reduce complexity in accounting standards. Adoption methods varied based on the specific tax items impacted. The adoption of this standard did not result in a material impact to the Company's financial statements and related disclosures. ASU 2020-01 Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323, and Topic 815: On January 1, 2021, Eastman prospectively adopted this update which provides clarification that an entity should consider observable transactions that require the application or discontinuance of the equity method of accounting for the purposes of applying the measurement alternative and clarification that certain forward contracts and purchased options to purchase securities that, upon settlement, would be accounted for under the equity method of accounting. The adoption of this standard did not result in a material impact to the Company's financial statements and related disclosures. ASU 2021-01 Reference Rate Reform (Topic 848): In January 2021, the FASB issued this update to clarify that certain optional expedients and exceptions under this topic for contract modifications and hedge accounting apply to derivatives instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform (the global financial markets transition in contracts, hedging relationships, and other transactions away from referencing the London Interbank Offered Rate (LIBOR) and other interbank offered rates and toward new reference rates). This update was effective immediately upon release. As the Company has not experienced any reference rate reform modification to date, this update will be adopted on a prospective basis in the event of such modifications. Accounting Standards Issued But Not Adopted as of March 31, 2021 None applicable to Eastman.
Off-Balance-Sheet Credit Exposure, Policy | Working Capital Management and Off Balance Sheet ArrangementsThe Company has an off balance sheet, uncommitted accounts receivable factoring program under which entire invoices may be sold, without recourse, to third-party financial institutions. Under these agreements, the Company sells the invoices at face value, less a transaction fee, which substantially equals the carrying value and fair value with no gain or loss recognized, and no credit loss exposure is retained. Available capacity under these agreements, which the Company uses as a routine source of working capital funding, is dependent on the level of accounts receivable eligible to be sold and the financial institutions' willingness to purchase such receivables. In addition, certain agreements also require that the Company continue to service, administer, and collect the sold accounts receivable at market rates. The total amounts sold in first quarter 2021 and 2020 were $289 million and $457 million, respectively.
