SIGNIFICANT ACCOUNTING POLICIES

SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
SIGNIFICANT ACCOUNTING POLICIES	Dec. 31, 2019
Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Financial Statement Presentation The consolidated financial statements of Eastman Chemical Company ("Eastman" or the "Company") and subsidiaries are prepared in conformity with accounting principles generally accepted ("GAAP") in the United States and of necessity include some amounts that are based upon management estimates and judgments. Future actual results could differ from such current estimates. The 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 in minority-owned companies 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 consolidated financial statements and accompanying footnotes to conform to current period presentation. Recently Adopted Accounting Standards Accounting Standards Update ("ASU") 2016-02 Leases: On January 1, 2019, Eastman adopted this standard, and related releases, under the modified retrospective optional transition method such that prior period financial statements have not been adjusted to reflect the impact of the new standard and adoption did not result in an impact to retained earnings. Upon adoption, operating right-to-use assets and lease liabilities were $219 million . The new standard establishes two types of leases: finance and operating. Both finance and operating leases have associated right-to-use assets and lease liabilities that have been valued at the present value of the lease payments and recognized on the Consolidated Statement of Financial Position. For further information, see Note 11, "Leases and Other Commitments" . ASU 2018-02 Income Statement - Reporting Comprehensive Income: On January 1, 2019, Eastman adopted this standard in the current period resulting in the reclassification of $20 million of stranded tax expense from accumulated other comprehensive income (loss) ("AOCI") to retained earnings as a result of the 2017 Tax Cuts and Jobs Act ("Tax Reform Act"). The amount of the reclassification is the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts and related valuation allowances related to items remaining in AOCI. ASU 2018-15 Internal-Use Software - Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract: On January 1, 2019, Eastman adopted this standard prospectively which did not result in a material impact on the Company's financial statements and related disclosures. ASU 2018-16 Derivatives and Hedging - Inclusion of the Secured Overnight Financing Rate ("SOFR") Overnight Index Swap ("OIS") Rate as a Benchmark Interest Rate for Hedge Accounting Purposes: On January 1, 2019, Eastman adopted this standard prospectively for qualifying new or redesignated hedging relationships. Management does not expect the adoption of this standard will materially impact the Company's financial statements and related disclosures. Accounting Standards Issued But Not Adopted as of December 31, 2019 ASU 2016-13 Financial Instruments - Credit Losses: In June 2016, the Financial Accounting Standards Board ("FASB") issued this standard relating to credit losses and subsequent related releases. The amendments require a financial asset (including trade receivables) to be presented at the net amount expected to be collected through the use of allowances for credit losses valuation account. The income statement will reflect the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. This standard is effective for annual reporting periods beginning after December 15, 2019. The new standard application is mixed among the various elements that include modified retrospective and prospective transition methods. Management does not expect that changes in its accounting required by the new standard will materially impact the Company's financial statements and related disclosures. ASU 2018-13 Fair Value Measurement - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement: In August 2018, the FASB issued this update as a part of its disclosure framework project to improve the effectiveness of disclosures in the notes to financial statements. The primary changes applicable to Eastman in this update are the disclosures of fair value levels, assessment thereof, and transfers between those levels. This standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Certain disclosure amendments are to be applied prospectively for only the most recent interim or annual period presented, while other amendments are to be applied retrospectively to all periods presented. Management does not expect that changes required by the new standard will materially impact the Company's related disclosures. ASU 2018-14 Retirement Benefits - Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans: In August 2018, the FASB issued this update as a part of its disclosure framework project to improve the effectiveness of disclosures in the notes to financial statements. The primary change impacting Eastman is the addition of disclosures related to significant gains and losses related to changes in the benefit obligation for the period and weighted-average interest crediting rates for cash balance plans. This standard is effective for fiscal years ending after December 15, 2020 and early adoption is permitted. Upon adoption, this update is to be applied on a retrospective basis to all periods presented. Management does not expect that changes required by the new standard will materially impact the Company's related disclosures. ASU 2018-18 Collaborative Arrangements - Clarifying the Interaction between Topic 808 (Collaborative Arrangements) and Topic 606 (Revenue from Contracts with Customers): In November 2018, the FASB issued clarification in regards to which contracts are accounted for under Topic 808 and Topic 606 as well as alignment of guidance between the two pronouncements. This standard is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Upon adoption, this update is to be applied retrospectively to the date of initial application of Topic 606. Management is currently evaluating the impact on the Company's financial statements and related disclosures. ASU 2019-01 Leases - Codification Improvements: In March 2019, the FASB issued this update in response to stakeholder inquiries regarding the new leasing standard. This standard is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Upon adoption, this update is to be applied as of the adoption date and under the same transition methodology of ASU 2016-02 Leases . Management is currently evaluating the impact on the Company's financial statements and related disclosures. ASU 2019-12 Income Taxes - Simplifying the Accounting for Income Taxes : In December 2019, the FASB issued this update as part of its initiative to reduce complexity in accounting standards which removes certain exceptions and provides simplification to specific tax items. This standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. Adoption methods vary based on the specific items impacted. Management is currently evaluating the impact on the Company's financial statements and related disclosures. Revenue Recognition On January 1, 2018, Eastman adopted ASU 2014-09 Revenue Recognition (ASC 606) under the modified retrospective method, such that revenue for all periods prior to January 1, 2018 continue to be reported under the previous standard, which resulted in an increase to retained earnings of $53 million after tax for products shipped but not delivered as of December 31, 2017. Eastman recognizes revenue when performance obligations of the sale are satisfied. Eastman sells to customers through master sales agreements or standalone purchase orders. The majority of the Company's terms of sale have a single performance obligation to transfer products. Accordingly, the Company recognizes revenue when control has been transferred to the customer, generally at the time of shipment of products. Eastman accounts for shipping and handling as activities to fulfill the promise to transfer the good and does not allocate revenue to those activities. All related shipping and handling costs are recognized at the time of shipment. Amounts collected for sales or other similar taxes are presented net of the related tax expense rather than presenting them as additional revenue. The incremental cost of obtaining a sales contract is recognized as a selling expense when incurred given the potential amortization period for such an asset is one year or less. The possible existence of a significant financing component within a sales contract is ignored when the time between cash collection and performance is less than one year. Finally, the Company does not disclose any unfulfilled obligations as customer purchase order commitments have an original expected duration of one year or less and no consideration from customers is excluded from the transaction price. The timing of Eastman's customer billings does not always match the timing of revenue recognition. When the Company is entitled to bill a customer in advance of the recognition of revenue, a contract liability is recognized. When the Company is not entitled to bill a customer until a period after the related recognition of revenue, a contract asset is recognized. Contract assets represent the Company's right to consideration for the exchange of goods under a contract, but which are not yet billable to a customer for consignment inventory or pursuant to certain shipping terms. Contract liabilities were not material as of December 31, 2019 or December 31, 2018 . Contract assets were $65 million and $62 million as of December 31, 2019 and December 31, 2018 , respectively, and are included as a component of "Miscellaneous receivables" in the Consolidated Statements of Financial Position. For additional information, see Note 19, "Segment and Regional Sales Information" . Pension and Other Postretirement Benefits Eastman maintains defined benefit pension plans that provide eligible employees with retirement benefits. Under its other postretirement benefit plans in the U.S., Eastman provides life insurance for eligible retirees hired prior to January 1, 2007. Eastman provides a subsidy for pre-Medicare health care and dental benefits to eligible retirees hired prior to January 1, 2007 that will end on December 31, 2021. Company funding is also provided for eligible Medicare retirees hired prior to January 1, 2007 with a health reimbursement arrangement. The estimated amounts of the costs and obligations related to these benefits reflect the Company's assumptions related to discount rates, expected return on plan assets, rate of compensation increase or decrease for employees, and health care cost trends. The estimated cost of providing plan benefits also depends on demographic assumptions including retirements, mortality, turnover, and plan participation. Eastman's pension and other postretirement benefit plans costs consist of two elements: 1) ongoing costs recognized quarterly, which are comprised of service and interest costs, expected returns on plan assets, and amortization of prior service credits; and 2) mark-to-market ("MTM") gains and losses recognized annually, in the fourth quarter of each year, primarily resulting from changes in actuarial assumptions for discount rates and the differences between actual and expected returns on plan assets. Any interim remeasurements triggered by a curtailment, settlement, or significant plan changes are recognized in the quarter in which such remeasurement event occurs. For additional information, see Note 10, "Retirement Plans" . Environmental Costs Eastman recognizes environmental remediation costs when it is probable that the Company has incurred a liability at a contaminated site and the amount can be reasonably estimated. When a single amount cannot be reasonably estimated but the cost can be estimated within a range, the Company recognizes the minimum undiscounted amount. This undiscounted amount reflects liabilities expected to be paid within approximately 30 years and the Company's assumptions about remediation requirements at the contaminated site, the nature of the remedy, the outcome of discussions with regulatory agencies and other potentially responsible parties at multi-party sites, and the number and financial viability of other potentially responsible parties. Changes in the estimates on which the accruals are based, unanticipated government enforcement action, or changes in health, safety, environmental, and chemical control regulations and testing requirements could result in higher or lower costs. The Company also establishes reserves for closure and post-closure costs associated with the environmental and other assets it maintains. Environmental assets include but are not limited to waste management units, such as landfills, water treatment facilities, and surface impoundments. When these types of assets are constructed or installed, a loss contingency reserve is established for the anticipated future costs associated with the retirement or closure of the asset based on its expected life and the applicable regulatory closure requirements. The Company recognizes the asset retirement obligations in the period in which they are incurred if a reasonable estimate of fair value can be made. The asset retirement obligations are discounted to expected present value and subsequently adjusted for changes in fair value. These future estimated costs are charged to earnings over the estimated useful life of the assets. If the Company changes its estimate of the environmental asset retirement obligation costs or its estimate of the useful lives of these assets, expenses charged to earnings will be impacted. The current portion of accruals for environmental liabilities is included in payables and other current liabilities and the long-term portion is included in other long-term liabilities. These accruals exclude claims for recoveries from insurance companies or other third parties. Environmental costs are capitalized if they extend the life of the related property, increase its capacity, or mitigate or prevent future contamination. The cost of operating and maintaining environmental control facilities is charged to expense as incurred. For additional information see Note 12, "Environmental Matters and Asset Retirement Obligations" . Share-based Compensation Eastman recognizes compensation expense in the financial statements for stock options and other share-based compensation awards based upon the grant-date fair value over the substantive vesting period. For additional information, see Note 17, "Share-Based Compensation Plans and Awards" . Restructuring of Operations Eastman records restructuring charges for costs incurred in connection with consolidation of operations, exited business or product lines, or shutdowns of specific sites that are expected to be substantially completed within twelve months. These restructuring charges are recorded as incurred, and are associated with site closures, legal and environmental matters, demolition, contract terminations, obsolete inventory, or other costs and charges directly related to the restructuring. The Company records severance charges for employee separations when the separation is probable and reasonably estimable. In the event employees are required to perform future service, the Company records severance charges ratably over the remaining service period of those employees. For additional information, see Note 15, "Asset Impairments and Restructuring Charges, Net" . Income Taxes The provision for (benefit from) income taxes has been determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for (benefit from) income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of Eastman's assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Provision has been made for income taxes on unremitted earnings of subsidiaries and affiliates, except for subsidiaries in which earnings are deemed to be indefinitely reinvested. The Company recognizes income tax positions that meet the more likely than not threshold and accrues interest related to unrecognized income tax positions which is recorded as a component of the income tax provision. In conjunction with its evaluation of the provisions of the Tax Reform Act, in 2018, the Company made an accounting policy election to account for taxes resulting from the global intangible low-tax income ("GILTI") as a component of the provision for income taxes. Cash and Cash Equivalents Cash and cash equivalents include cash, time deposits, and readily marketable securities with original maturities of three months or less. Fair Value Measurements Eastman records recurring and non-recurring financial assets and liabilities as well as all non-financial assets and liabilities subject to fair value measurement at the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. These fair value principles prioritize valuation inputs across three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company's assumptions used to measure assets and liabilities at fair value. An asset or liability's classification within the various levels is determined based on the lowest level input that is significant to the fair value measurement. Accounts Receivable and Allowance for Doubtful Accounts Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Eastman maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The Company calculates the allowance based on an assessment of the risk in the accounts receivable portfolio. Write-offs are recorded at the time a customer receivable is deemed uncollectible. Allowance for doubtful accounts was $11 million at both December 31, 2019 and 2018 . The Company does not enter into receivables of a long-term nature, also known as financing receivables, in the normal course of business. Inventories Inventories measured by the last-in, first-out ("LIFO") method are valued at the lower of cost or market and inventories measured by the first-in, first-out ("FIFO") method are valued at lower cost or net realizable value. Eastman determines the cost of most raw materials, work in process, and finished goods inventories in the United States and Switzerland by the LIFO method. The cost of all other inventories is determined by the average cost method, which approximates the FIFO method. The Company writes-down its inventories equal to the difference between the carrying value of inventory and the estimated market value or net realizable value based upon assumptions about future demand and market conditions. Properties Eastman records properties at cost. Maintenance and repairs are charged to earnings; replacements and betterments are capitalized. When Eastman retires or otherwise disposes of assets, it removes the cost of such assets and related accumulated depreciation from the accounts. The Company records any profit or loss on retirement or other disposition into earnings. Asset impairments are reflected as increases in accumulated depreciation for properties that have been placed in service. In instances when an asset has not been placed in service and is impaired, the associated costs are removed from the appropriate property accounts. Depreciation and Amortization Depreciation expense is calculated based on historical cost and the estimated useful lives of the assets, generally using the straight-line method. Estimated useful lives for buildings and building equipment generally range from 20 to 50 years. Estimated useful lives generally ranging from 3 to 33 years are applied to machinery and equipment in the following categories: computer software (3 to 5 years); office furniture and fixtures and computer equipment (5 to 10 years); vehicles, railcars, and general machinery and equipment (5 to 20 years); and manufacturing-related improvements (20 to 33 years). Accelerated depreciation is reported when the estimated useful life is shortened and continues to be reported in cost of sales. Amortization expense for definite-lived intangible assets is generally determined using a straight-line method over the estimated useful life of the asset. Amortization expense is reported in cost of sales. For additional information, see Note 4, "Goodwill and Other Intangible Assets" . Impairment of Long-Lived Assets Definite-lived Assets Properties and equipment and definite-lived intangible assets to be held and used by Eastman are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The review of properties and equipment and the review of definite-lived intangible assets is performed at the asset group level, which is the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. If the carrying amount is not considered to be recoverable, an analysis of fair value is triggered. An impairment is recognized for the excess of the carrying amount of the asset over the fair value. Fair value is the price that would be received to sell an asset in an orderly transaction between market participants. Goodwill Eastman conducts testing of goodwill annually in the fourth quarter or more frequently when events and circumstances indicate an impairment may have occurred. The testing of goodwill is performed at the "reporting unit" level which the Company has determined to be its "components". Components are defined as an operating segment or one level below an operating segment, and in order to be a reporting unit, the component must 1) be a "business" as defined by applicable accounting standards (an integrated set of activities and assets that is capable of being conducted and managed for the purpose of providing a return in the form of dividends, lower costs, or other economic benefits directly to the investors or other owners, members, or participants); 2) have discrete financial information available; and 3) be reviewed regularly by Company operating segment management. The Company aggregates certain components into reporting units based on economic similarities. A reporting unit's goodwill is considered to be impaired when the reporting unit's estimated fair value is less than its carrying value. The Company uses an income approach and applies a discounted cash flow model in testing the carrying value of goodwill for each reporting unit. Key assumptions and estimates used in the Company's 2019 goodwill impairment testing included projections of revenues and earnings before interest and taxes ("EBIT") determined using the Company's annual multi-year strategic plan, the estimated weighted average cost of capital ("WACC") and a projected long-term growth rate. The Company believes these assumptions are consistent with those a hypothetical market participant would use given circumstances that were present at the time the estimates were made. However, actual results and amounts may be significantly different from the Company's estimates. In addition, the use of different estimates or assumptions could result in materially different estimated fair values of reporting units. The WACC is calculated incorporating weighted average returns on debt and equity from market participants. Therefore, changes in the market, which are beyond the control of the Company, may have an impact on future calculations of estimated fair value. Indefinite-lived Intangible Assets Eastman conducts testing of indefinite-lived intangible assets annually in the fourth quarter or more frequently when events and circumstances indicate an impairment may have occurred. The carrying value of an indefinite-lived intangible asset is considered to be impaired when the fair value, as established by appraisal or based on discounted future cash flows of certain related products, is less than the respective carrying value. Indefinite-lived intangible assets, consisting primarily of various tradenames, are tested for potential impairment by comparing the estimated fair value to the carrying amount. The Company uses an income approach, specifically the relief from royalty method, to test indefinite-lived intangible assets. The estimated fair value of tradenames is determined based on an assumed royalty rate savings, discounted by the calculated market participant WACC plus a risk premium. For additional information, see Note 4, "Goodwill and Other Intangible Assets" . Leases As noted above, On January 1, 2019, Eastman adopted ASU 2016-02 Leases. For accounting policy and elections, see Note 11, "Leases and Other Commitments" . Investments The consolidated financial statements include the accounts of Eastman and all its subsidiaries and entities or joint ventures in which a controlling interest is maintained. The Company includes its share of earnings and losses of such investments in "Net earnings attributable to Eastman" and "Comprehensive income attributable to Eastman" located in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings and in "Total equity" located in the Consolidated Statements of Financial Position. Investments in affiliates over which the Company has significant influence but not a controlling interest are carried on the equity basis. Under the equity method of accounting, these investments are included in "Other noncurrent assets" in the Consolidated Statements of Financial Position. The Company includes its share of earnings and losses of such investments in "Other (income) charges, net" located in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings. Derivative and Non-Derivative Financial Instruments Eastman uses derivative and non-derivative instruments to manage its exposure to market risks, such as changes in foreign currency exchange rates, commodity prices, and interest rates. The Company does not enter into derivative transactions for speculative purposes. Counterparties to the derivative contracts are highly rated financial institutions which the Company believes carry minimal risk of nonperformance and the Company diversifies its positions among such counterparties to reduce its exposure to counterparty risk and credit losses. The Company monitors the creditworthiness of its counterparties on an ongoing basis. The Company's derivative instruments are recognized as either assets or liabilities on the Consolidated Statements of Financial Position and measured at fair value. For qualifying derivatives designated as cash flow hedges, the effective portion of the changes in the fair value are reported as a component of AOCI in the Consolidated Statements of Financial Position and recognized in earnings when the hedged items affect earnings. For qualifying derivatives designated as fair value hedges, the effective portion of the changes in the fair value are reported as "Long-term borrowings" on the Consolidated Statements of Financial Position and recognized in earnings when the hedged items affect earnings. For qualifying derivative or non-derivative instruments designated as net investment hedges, the net change in the hedge instrument and item being hedged is reported as a component of "Cumulative translation adjustment" ("CTA") within AOCI located in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings. Any hedge components excluded from the assessment of effectiveness are recognized in earnings, the initial value of the excluded component, using a systematic and rational method over the life of the hedging instrument. Changes in the fair value of nonqualifying derivatives or derivatives that are not designated as hedges, are recognized in current earnings. Hedge accounting will be discontinued prospectively for all hedges that no longer qualify for hedge accounting treatment. Cash flows from derivative instruments designated as hedges are reported in the same category as the cash flows from the items being hedged. For additional information, see Note 9, "Derivative and Non-Derivative Financial Instruments" . Litigation and Contingent Liabilities Eastman and its operations from time to time are, and in the future may be, parties to or targets of lawsuits, claims, investigations and proceedings, including product liability, personal injury, asbestos, patent and intellectual property, commercial, contract, environmental, antitrust, health and safety, and employment matters, which are handled and defended in the ordinary course of business. The Company accrues a contingent loss liability for such matters when it is probable that a liability has been incurred and the amount can be reasonably estimated. When a single amount cannot be reasonably estimated but the cost can be estimated within a range, the Company accrues the minimum amount. The Company expenses legal costs, including those expected to be incurred in connection with a loss contingency, as incurred. Working Capital Management and Off Balance Sheet Arrangements The Company works with suppliers to optimize payment terms and conditions on accounts payable to enhance timing of working capital and cash flows. As part of these efforts, in 2019, the Company introduced a voluntary supply chain finance program to provide suppliers with the opportunity to sell receivables due from Eastman to a participating financial institution. Eastman's responsibility is limited to making payments on the terms originally negotiated with suppliers, regardless of whether the suppliers sells their receivables to the financial institution. The range of payment terms Eastman negotiates with suppliers are consistent, regardless of whether a supplier participates in the program. All of Eastman's accounts payable and associated payments are reported consistently in the Company's Consolidated Statements of Financial Position and Consolidated Statements of Cash Flows regardless of whether they are associated with a vendor who participates in the program. In 2019 , the Company expanded off balance sheet, uncommitted accounts receivable factoring agreements 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 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 coll

A reporting unit's goodwill is considered to be impaired when the reporting unit's estimated fair value is less than its carrying value. The Company uses an income approach and applies a discounted cash flow model in testing the carrying value of goodwill for each reporting unit. Key assumptions and estimates used in the Company's 2019 goodwill impairment testing included projections of revenues and EBIT determined using the Company's annual multi-year strategic plan, the estimated WACC, and a projected long-term growth rate. As a result of the goodwill impairment testing performed during fourth quarter 2019 , fair values were determined to exceed the carrying values for each reporting unit tested with the exception of crop protection (part of the Additives & Functional Products ("AFP") segment). In fourth quarter 2019 and 2018, as a result of the annual impairment test of goodwill, the Company recognized goodwill impairments of $45 million and $38 million , respectively, in the crop protection reporting unit. The impairment in 2019 was primarily due to the impact of recent regulatory changes in the European Union on current period and forecasted revenue and EBIT and a decrease in the long-term growth rate for the reporting unit assumed in the goodwill impairment model. The impairment in 2018 was primarily due to the WACC applied to the impairment analysis and the estimated impact of future regulatory changes. The crop protection reporting unit's goodwill after the reduction for impairment was $190 million as of December 31, 2019 . As of December 31, 2019, the reported balance of goodwill included accumulated impairment losses of $106 million , $12 million , and $14 million in the AFP segment, Chemical Intermediates ("CI") segment, and other segments, respectively. As of December 31, 2018, the reported balance of goodwill included accumulated impairment losses of $61 million , $12 million , and $14 million in the AFP segment, CI segment, and other segments, respectively.

The 2019 effective tax rate includes a $7 million increase to the provision for income taxes resulting from adjustments to the net tax benefit recognized in fourth quarter 2017 resulting from tax law changes, primarily the Tax Reform Act. The 2019 effective tax rate also includes adjustments to the tax provision to reflect finalization of prior year's income tax returns and an increase to state income taxes related to additional valuation allowance provided against state income tax credits. The 2018 effective tax rate included the impact of the U.S. corporate tax rate reduction resulting from the Tax Reform Act and the repeal of the domestic manufacturing deduction. The 2018 effective tax rate also included a $20 million increase to the provision for income taxes resulting from adjustments to the net tax benefit recognized in fourth quarter 2017 resulting from tax law changes, primarily the Tax Reform Act. These adjustments related to the one-time transition tax on deferred foreign income and changes in valuation of deferred tax assets associated with tax law changes and outside-U.S. entity reorganizations as part of the formation of an international treasury services center. The 2017 effective tax rate included a $339 million net tax benefit, primarily resulting from the Tax Reform Act, and a tax loss from outside-U.S. entity reorganizations as part of the formation of an international treasury services center. The net tax benefit included a benefit from the one-time revaluation of deferred tax liabilities, partially offset by a one-time transition tax on deferred foreign income and changes in valuation of deferred tax assets associated with tax law changes and outside-U.S. entity reorganizations as part of the formation of an international treasury services center. The 2017 effective tax rate also included a $20 million benefit due to amendments to prior years' domestic income tax returns, and a $30 million benefit reflecting the finalization of prior years' foreign income tax returns. The 2017 effective tax rate also included an $8 million tax benefit due to a tax ruling permitting deductibility of a liquidation loss on a previously impaired site. The U.S. Department of Treasury has issued a number of proposed regulations related to implementation of the provisions of the Tax Reform Act and certain states may issue clarifying guidance regarding state income tax conformity to the current federal tax code. Finalization of these regulations in future periods may result in changes in the period of enactment to the amounts currently reported in the Consolidated Statements of Financial Position. As of December 31, 2019 and 2018, a non-current income tax payable of approximately $6 million and $56 million , respectively, attributable to the transition tax is reflected in "Other long-term liabilities" of the Consolidated Statements of Financial Position. In conjunction with its evaluation of the provisions of the Tax Reform Act, in 2018, the Company made an accounting policy election to account for taxes resulting from GILTI as a component of the provision for income taxes. The significant components of deferred tax assets and liabilities follow: December 31, (Dollars in millions) 2019 2018 (1) Deferred tax assets Post-employment obligations $ 247 $ 230 Net operating loss carryforwards 606 634 Tax credit carryforwards 239 239 Environmental reserves 68 70 Unrealized derivative loss 18 18 Other 173 94 Total deferred tax assets 1,351 1,285 Less: Valuation allowance 453 487 Deferred tax assets less valuation allowance $ 898 $ 798 Deferred tax liabilities Property, plant, and equipment $ (895 ) $ (856 ) Intangible assets (439 ) (473 ) Investments (235 ) (179 ) Other (178 ) (131 ) Total deferred tax liabilities $ (1,747 ) $ (1,639 ) Net deferred tax liabilities $ (849 ) $ (841 ) As recorded in the Consolidated Statements of Financial Position: Other noncurrent assets $ 66 $ 43 Deferred income tax liabilities (915 ) (884 ) Net deferred tax liabilities $ (849 ) $ (841 ) (1) Revised from Note 7, "Income Taxes" , to the Company's 2018 Annual Report on Form 10-K, which reported net operating loss carryforwards as $708 million , valuation allowance as $466 million , and investments as $(274) million . Beginning January 1, 2019, the Company did not assert indefinite reinvestment on short-term liquid assets of certain foreign subsidiaries. All other foreign earnings, including basis differences, continue to be considered indefinitely reinvested. As of December 31, 2019 unremitted earnings of subsidiaries outside the U.S. totaled approximately $2.5 billion of which a substantial portion has already been subject to U.S. tax. The Company has not determined the deferred tax liability associated with these unremitted earnings and basis differences, as such determination is not practicable. For certain consolidated foreign subsidiaries, income and losses directly flow through to taxable income in the U.S. These entities are also subject to taxation in the foreign tax jurisdictions. Net operating loss carryforwards exist to offset future taxable income in foreign tax jurisdictions and valuation allowances are provided to reduce deferred related tax assets if it is more likely than not that this benefit will not be realized. Changes in the estimated realizable amount of deferred tax assets associated with net operating losses for these entities could result in changes in the deferred tax asset valuation allowance in the foreign tax jurisdiction. At the same time, because these entities are also subject to tax in the U.S., a deferred tax liability for the expected future taxable income will be established concurrently. Therefore, the impact of any reversal of valuation allowances on consolidated income tax expense will be only to the extent that there are differences between the U.S. statutory tax rate and the tax rate in the foreign jurisdiction. A valuation allowance of $24 million at December 31, 2019 has been provided against the deferred tax asset resulting from these operating loss carryforwards. At December 31, 2019 , foreign net operating loss carryforwards totaled $2.1 billion . Of this total, $23 million will expire in 1 to 20 years and $2.1 billion have no expiration date. A valuation allowance of approximately $262 million has been provided against such net operating loss carryforwards. At December 31, 2019 , federal net operating loss carryforwards of $8 million were available to offset future taxable income, which expire from 2028 to 2030. At December 31, 2019 , foreign tax credit carryforwards of approximately $75 million were available to reduce possible future U.S. income taxes and which expire from 2020 to 2028. As a result of the Tax Reform Act, the Company may no longer be able to utilize certain U.S. foreign tax credit carryforwards. A valuation allowance of $45 million has been established on a portion of deferred tax assets as of December 31, 2019 . At December 31, 2019 , a partial valuation allowance of $72 million has been provided against state tax credits that the Company may not be able to utilize. A partial valuation allowance of $47 million has been established for the Solutia, Inc. ("Solutia") state net operating loss carryforwards. The valuation allowance will be retained until there is sufficient positive evidence to conclude that it is more likely than not that the deferred tax assets will be realized, or the related statute expires.

Eastman files income tax returns in the U.S. and various state and foreign jurisdictions. The Company is no longer subject to U.S. Federal income tax examinations by tax authorities for years before 2011 for Eastman legal entities and years before 2002 for Solutia legal entities. With few exceptions, Eastman is no longer subject to state and local income tax examinations by tax authorities for years before 2011. Solutia and related subsidiaries are no longer subject to state and local income tax examinations for years before 2000. With few exceptions, the Company is no longer subject to foreign income tax examinations by tax authorities for tax years before 2011. It is reasonably possible that, as a result of the resolution of federal, state, and foreign examinations and appeals, and the expiration of various statutes of limitation, unrecognized tax benefits could decrease within the next twelve months by up to $28 million .

The carrying value of these euro-denominated borrowings have been designated as non-derivative net investment hedges of a portion of the Company's net investments in euro functional-currency denominated subsidiaries to offset foreign currency fluctuations. In fourth quarter 2019 , the Company repaid the 2.7% notes due January 2020 ( $250 million principal) using available cash. There were no material debt extinguishment costs associated with the early repayment of this debt. The total consideration for this redemption is reported under financing activities on the Consolidated Statements of Cash Flows. In fourth quarter 2018, the Company sold 3.5% notes due December 2021 in the principal amount of $300 million and 4.5% notes due December 2028 in the principal amount of $500 million . Net proceeds from the notes were $789 million and were used, together with available cash, for the early and full repayment of the 5.5% notes due November 2019 ( $250 million principal) and the partial redemption of the 2.7% notes due January 2020 ( $550 million principal). Total consideration for these redemptions was $806 million ( $800 million total principal and $6 million for the early redemption premiums) and is reported as financing activities on the Consolidated Statements of Cash Flows. The early repayment resulted in a charge of $7 million for early debt extinguishment costs which were primarily attributable to the early redemption premiums and related unamortized costs. The book value of the redeemed debt was $799 million . Revolving Credit Facilities and Commercial Paper Borrowings The Company has access to a $1.50 billion revolving credit agreement (the "Credit Facility") expiring October 2023. Borrowings under the Credit Facility are subject to interest at varying spreads above quoted market rates and a commitment fee is paid on the total unused commitment. The Credit Facility provides available liquidity for general corporate purposes and supports commercial paper borrowings. Commercial paper borrowings are classified as short-term. At December 31, 2019 and 2018 , the Company had no outstanding borrowings under the Credit Facility. At December 31, 2019 , commercial paper borrowings were $170 million with a weighted average interest rate of 2.03 percent . At December 31, 2018 , the Company's commercial paper borrowings were $130 million with a weighted average interest rate of 2.91 percent . The Company has access to up to $250 million under an accounts receivable securitization agreement (the "A/R Facility") that expires April 2020. Eastman Chemical Financial Corporation ("ECFC"), a subsidiary of the Company, has an agreement to sell interests in trade receivables under the A/R Facility to a third party purchaser. Third party creditors of ECFC have first priority claims on the assets of ECFC before those assets would be available to satisfy the Company's general obligations. Borrowings under the A/R Facility are subject to interest rates based on a spread over the lender's borrowing costs, and ECFC pays a fee to maintain availability of the A/R Facility. At December 31, 2019 , the Company had no borrowings under the A/R Facility. At December 31, 2018 , the Company's borrowings under the A/R Facility were $50 million with an interest rate of 3.39 percent . Through September 2019, the Company had access to borrowings of up to €150 million ( $163 million ) under a receivables facility based on the discounted value of selected customer accounts receivable. These arrangements included receivables in the United States, Belgium, and Finland, and were subject to various eligibility requirements. Borrowings under this facility were subject to interest at an agreed spread above LIBOR and EURIBOR plus administration and insurance fees and were classified as short-term. In October 2019, this receivables facility was terminated and the balance was repaid using available A/R Facility borrowings. At December 31, 2018 , the Company's amount of outstanding borrowings under this facility were $112 million with a weighted average interest rate of 1.70 percent . The Credit Facility and A/R Facility contain customary covenants, including requirements to maintain certain financial ratios, that determine the events of default, amounts available, and terms of borrowings. The Company was in compliance with all covenants at both December 31, 2019 and December 31, 2018 . Fair Value of Borrowings Eastman has classified its total borrowings at December 31, 2019 and 2018 under the fair value hierarchy as defined in the accounting policies in Note 1, "Significant Accounting Policies" . The fair value for fixed-rate debt securities is based on quoted market prices for the same or similar debt instruments and is classified as Level 2. The fair value for the Company's other borrowings primarily under the commercial paper and receivables facility equals the carrying value and is classified as Level 2. At December 31, 2019 and 2018 , the fair value of total borrowings was $6.275 billion and $6.216 billion , respectively. The Company had no borrowings classified as Level 1 or Level 3 as of December 31, 2019 and 2018 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVE AND NON-DERIVATIVE FINANCIAL INSTRUMENTS Overview of Hedging Programs Eastman is exposed to market risks, such as changes in foreign currency exchange rates, commodity prices, and interest rates. To mitigate these market risks and their effects on the cash flows of the underlying transactions and investments in foreign subsidiaries, the Company uses various derivative and non-derivative financial instruments, when appropriate, in accordance with the Company's hedging strategy and policies. Designation is performed on a specific exposure basis to support hedge accounting. The Company does not enter into derivative transactions for speculative purposes. Cash Flow Hedges Cash flow hedges are derivative instruments designated as and used to hedge the exposure to variability in expected future cash flows that are attributable to a particular risk. The derivative instruments that are designated and qualify as a cash flow hedge are reported on the balance sheet at fair value and the changes in fair value of these hedging instruments are offset in part or in whole by corresponding changes in the anticipated cash flows of the underlying exposures being hedged. The change in the hedge instrument is reported as a component of AOCI located in the Consolidated Statements of Financial Position and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Cash flows from cash flow hedges are classified as operating activities in the Consolidated Statements of Cash Flows. Foreign Currency Exchange Rate Hedging Eastman manufactures and sells its products in a number of countries throughout the world and, as a result, is exposed to changes in foreign currency exchange rates. To manage the volatility relating to these exposures, the Company nets the exposures on a consolidated basis to take advantage of natural offsets. To manage the remaining exposure, the Company enters into currency option and forward cash flow hedges to hedge probable anticipated, but not yet committed, export sales and purchase transactions expected within a rolling three year period and denominated in foreign currencies (principally the euro). Additionally, the Company, from time to time, enters into forward exchange contract cash flow hedges to hedge certain firm commitments denominated in foreign currencies. Commodity Hedging Certain raw material and energy sources used by Eastman, as well as sales of certain commodity products by the Company, are subject to price volatility caused by weather, supply and demand conditions, economic variables and other unpredictable factors. This volatility is primarily related to the market pricing of propane, ethane, natural gas, paraxylene, ethylene, and benzene. In order to mitigate expected fluctuations in market prices, from time to time, the Company enters into option and forward contracts and designates these contracts as cash flow hedges. The Company currently hedges commodity price risks using derivative financial instrument transactions within a rolling three year period. The Company weights its hedge portfolio more heavily in the first year with declining coverage over the remaining periods. Interest Rate Hedging Eastman's policy is to manage interest expense using a mix of fixed and variable rate debt. To manage interest rate risk effectively, the Company, from time to time, enters into cash flow interest rate derivative instruments, primarily forward starting swaps and treasury locks, to hedge the Company's exposure to movements in interest rates prior to anticipated debt offerings. These instruments are designated as cash flow hedges. Fair Value Hedges Fair value hedges are defined as derivative or non-derivative instruments designated as and used to hedge the exposure to changes in the fair value of an asset or a liability or an identified portion thereof that is attributable to a particular risk. The derivative instruments that are designated and qualify as fair value hedges are recognized on the balance sheet at fair value and the changes in fair value of these hedging instruments are offset in part or in whole by corresponding changes in the anticipated fair value of the underlying exposures being hedged. The net of the change in the hedge instrument and item being hedged for qualifying fair value hedges is recognized in earnings in the same period or periods during which the hedged transaction affects earnings. Cash flows from fair value hedges are classified as operating activities in the Consolidated Statements of Cash Flows. Interest Rate Hedging Eastman's policy is to manage interest expense using a mix of fixed and variable rate debt. To manage the Company's mix of fixed and variable rate debt effectively, from time to time, the Company enters into interest rate swaps in which the Company agrees to exchange the difference between fixed and variable interest amounts calculated by reference to an agreed upon notional principal amount. These swaps are designated as hedges of the fair value of the underlying debt obligations and the interest rate differential is reflected as an adjustment to interest expense over the life of the swaps. Net Investment Hedges Net investment hedges are defined as derivative or non-derivative instruments designated as and used to hedge the foreign currency exposure of the net investment in certain foreign operations. The net of the change in the hedge instrument and item being hedged for qualifying net investment hedges is reported as a component of the CTA within AOCI located in the Consolidated Statements of Financial Position. Recognition in earnings of amounts previously recognized in CTA is limited to circumstances such as complete or substantially complete liquidation of the net investment in the hedged foreign operation. In the event of a complete or substantially complete liquidation of the net investment, cash flows from net investment hedges are classified as investing activities in the Consolidated Statements of Cash Flows. For derivative cross-currency interest rate swap net investment hedges, gains and losses representing hedge components excluded from the assessment of effectiveness are recognized in CTA within AOCI and recognized in earnings through the periodic swap interest accruals. The cross-currency interest rate swaps designated as net investment hedges are included as part of "Other long-term liabilities" or "Other noncurrent assets" within the Consolidated Statements of Financial Position. Cash flows from excluded components are classified as operating activities in the Consolidated Statements of Cash Flows. In January 2018, Eastman entered into fixed-to-fixed cross-currency swaps and designated these swaps to hedge a portion of its net investment in a euro functional currency denominated subsidiary against foreign currency fluctuations. These contracts involve the exchange of fixed U.S. dollars with fixed euro interest payments periodically over the life of the contracts and an exchange of the notional amounts at maturity. The fixed-to-fixed cross-currency swaps include €150 million ( $180 million ) maturing January 2021 and €266 million ( $320 million ) maturing August 2022. In October 2018, Eastman entered into fixed-to-fixed cross-currency swaps and designated these swaps to hedge a portion of its net investment in a euro functional currency denominated subsidiary against foreign currency fluctuations. These contracts involve the exchange of fixed U.S. dollars with fixed euro interest payments periodically over the life of the contracts and an exchange of the notional amounts at maturity. The fixed-to-fixed cross-currency swaps include €165 million ( $190 million ) maturing January 2024, €104 million ( $120 million ) maturing March 2025, and €165 million ( $190 million ) maturing February 2027. Summary of Financial Position and Financial Performance of Hedging Instruments The following table presents the notional amounts outstanding at December 31, 2019 and 2018 associated with Eastman's hedging programs. Notional Outstanding December 31, 2019 December 31, 2018 Derivatives designated as cash flow hedges: Foreign Exchange Forward and Option Contracts (in millions) EUR/USD (in EUR) €630 €263 Commodity Forward and Collar Contracts Feedstock (in million barrels) 1 5 Energy (in million british thermal units) 27 40 Derivatives designated as fair value hedges: Fixed-for-floating interest rate swaps (in millions) $75 $75 Derivatives designated as net investment hedges: Cross-currency interest rate swaps (in millions) EUR/USD (in EUR) €851 €851 Non-derivatives designated as net investment hedges: Foreign Currency Net Investment Hedges (in millions) EUR/USD (in EUR) €1,243 €1,241 Fair Value Measurements For additional information on fair value measurement, see Note 1, "Significant Accounting Policies" . All the Company's derivative assets and liabilities are currently classified as Level 2. Level 2 fair value is based on estimates using standard pricing models. These standard pricing models use inputs that are derived from or corroborated by observable market data such as interest rate yield curves and currency spot and forward rates. The fair value of commodity contracts is derived using forward curves supplied by an industry recognized and unrelated third party. In addition, on an ongoing basis, the Company tests a subset of its valuations against valuations received from the transaction's counterparty to validate the accuracy of its standard pricing models. Counterparties to these derivative contracts are highly rated financial institutions which the Company believes carry minimal risk of nonperformance and the Company diversifies its positions among such counterparties to reduce its exposure to counterparty risk and credit losses. The Company monitors the creditworthiness of its counterparties on an ongoing basis. The Company did not realize a credit loss during the years ended December 31, 2019 or 2018 . All the Company's derivative contracts are subject to master netting arrangements, or similar agreements, which provide for the option to settle contracts on a net basis when they settle on the same day and in the same currency. In addition, these arrangements provide for a net settlement of all contracts with a given counterparty in the event that the arrangement is terminated due to the occurrence of default or a termination event. The Company does not have any cash collateral due under such agreements. The Company has elected to present derivative contracts on a gross basis within the Consolidated Statements of Financial Position. The following table presents the financial assets and liabilities valued on a recurring and gross basis and includes where the financial assets and liabilities are located within the Consolidated Statements of Financial Position as of December 31, 2019 and 2018 .

The designated foreign currency-denominated borrowings are included as part of "Long-term borrowings" within the Consolidated Statements of Financial Position. As of December 31, 2019 and 2018 , the following amounts were included within the Consolidated Statements of Financial Position related to cumulative basis adjustments for fair value hedges.

These derivatives are not designated as hedges due to the short-term nature and the gains or losses on these derivatives are marked-to-market in line item "Other (income) charges, net" of the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings. The Company recognized a net loss of $2 million and net loss of $13 million during 2019 and 2018 , respectively, on these derivatives. Pre-tax monetized positions and MTM gains and losses from raw materials and energy, currency, and certain interest rate hedges that were included in AOCI included losses of $50 million at December 31, 2019 and losses of $112 million at December 31, 2018 . Losses in AOCI decreased in 2019 compared to 2018 primarily as a result of a decrease in foreign currency exchange rates, particularly the euro. If realized, approximately $24 million in pre-tax losses will be reclassified into earnings during the next 12 months.

Retirement Benefits [Abstract]
RETIREMENT PLANS	RETIREMENT PLANS As described below, Eastman offers various postretirement benefits to its employees. Defined Contribution Plans Eastman sponsors a defined contribution employee stock ownership plan (the "ESOP"), which is a component of the Eastman Investment Plan and Employee Stock Ownership Plan ("EIP/ESOP"), under Section 401(a) of the Internal Revenue Code. Eastman made a contribution in February 2020 to the EIP/ESOP for substantially all U.S. employees equal to 5 percent of their eligible compensation for the 2019 plan year. Employees may allocate contributions to other investment funds within the EIP from the ESOP at any time without restrictions. Allocated shares in the ESOP totaled 2,076,203 ; 2,119,614 ; and 2,130,176 shares as of December 31, 2019 , 2018 , and 2017 , respectively. Dividends on shares held by the EIP/ESOP are charged to retained earnings. All shares held by the EIP/ESOP are treated as outstanding in computing earnings per share ("EPS"). In 2006, the Company amended its EIP/ESOP to provide a Company match of 50 percent of the first 7 percent of an employee's compensation contributed to the plan for employees who are hired on or after January 1, 2007. Employees who are hired on or after January 1, 2007, are also eligible for the contribution to the ESOP as described above. Charges for domestic contributions to the EIP/ESOP were $68 million , $67 million , and $64 million for 2019 , 2018 , and 2017 , respectively. Defined Benefit Pension Plans and Other Postretirement Benefit Plans Pension Plans Eastman maintains defined benefit pension plans that provide eligible employees with retirement benefits. Effective January 1, 2000, the Company's Eastman Retirement Assistance Plan, a U.S. defined benefit pension plan, was amended. Employees' accrued pension benefits earned prior to January 1, 2000 are calculated based on previous plan provisions using the employee's age, years of service, and final average compensation as defined in the plans. The amended plan uses a pension equity formula to calculate an employee's retirement benefits from January 1, 2000 forward. Benefits payable will be the combined pre-2000 and post-1999 benefits. Employees hired on or after January 1, 2007 are not eligible to participate in Eastman's U.S. defined benefit pension plans. Benefits are paid to employees from trust funds. Contributions to the trust funds are made as permitted by laws and regulations. The pension trust funds do not directly own any of the Company's common stock. Pension coverage for employees of Eastman's non-U.S. operations is provided, to the extent deemed appropriate, through separate plans. The Company systematically provides for obligations under such plans by depositing funds with trustees, under insurance policies, or by book reserves. Other Postretirement Benefit Plans Under its other postretirement benefit plans in the U.S., Eastman provides life insurance for eligible retirees hired prior to January 1, 2007. Eastman provides a subsidy for pre-Medicare health care and dental benefits to eligible retirees hired prior to January 1, 2007 that will end on December 31, 2021. Company funding is also provided for eligible Medicare retirees hired prior to January 1, 2007 with a health reimbursement arrangement. A few of the Company's non-U.S. operations have supplemental health benefit plans for certain retirees, the cost of which is not significant to the Company. Below is a summary balance sheet of the change in plan assets during 2019 and 2018 , the funded status of the plans and amounts recognized in the Consolidated Statements of Financial Position.

Plan Assumptions The assumptions used to develop the projected benefit obligation for Eastman's significant U.S. and non-U.S. defined benefit pension plans and U.S. postretirement benefit plans are provided in the following tables. Pension Plans Postretirement Benefit Plans 2019 2018 2017 2019 2018 2017 Weighted-average assumptions used to determine benefit obligations for years ended December 31: U.S. Non-U.S. U.S. Non-U.S. U.S. Non-U.S. Discount rate 3.25 % 1.56 % 4.29 % 2.35 % 3.57 % 2.25 % 3.21 % 4.26 % 3.54 % Rate of compensation increase 3.25 % 2.94 % 3.25 % 2.94 % 3.25 % 2.95 % 3.25 % 3.25 % 3.25 % Health care cost trend Initial 6.50 % 6.50 % 6.75 % Decreasing to ultimate trend of 5.00 % 5.00 % 5.00 % in year 2026 2025 2025 Weighted-average assumptions used to determine net periodic cost for years ended December 31: U.S. Non-U.S. U.S. Non-U.S. U.S. Non-U.S. Discount rate 4.29 % 2.35 % 3.57 % 2.25 % 3.89 % 2.33 % 4.26 % 3.54 % 3.91 % Discount rate for service cost 4.32 % 2.35 % 3.64 % 2.25 % 3.89 % 2.33 % 4.05 % 3.28 % 4.31 % Discount rate for interest cost 3.96 % 2.35 % 3.18 % 2.25 % 3.24 % 2.33 % 3.93 % 3.14 % 3.28 % Expected return on assets 7.43 % 4.49 % 7.48 % 4.83 % 7.49 % 5.02 % 3.75 % 3.75 % 3.75 % Rate of compensation increase 3.25 % 2.94 % 3.25 % 2.95 % 3.25 % 2.94 % 3.25 % 3.25 % 3.25 % Health care cost trend Initial 6.50 % 6.75 % 7.00 % Decreasing to ultimate trend of 5.00 % 5.00 % 5.00 % in year 2025 2025 2021 The Company calculates service and interest cost components of net periodic benefit costs for its significant defined benefit pension and other postretirement benefit plans by applying the specific spot rates along the yield curve to the plans' projected cash flows. A 6.50 percent rate of increase in per capita cost of covered health care benefits is assumed for 2020 . The rate is assumed to decrease gradually to five percent in 2026 and remain at that level thereafter. A one percent increase or decrease in health care cost trend would have had no material impact on the 2019 service and interest costs or the 2019 benefit obligation, because the Company's contributions for benefits are fixed. In 2017, the Company performed a five year experience study on assumptions for the U.S. plans, including a review of the mortality tables. As a result of the study, the Company has updated the mortality assumptions used to a modified RP-2017 table with a modified MP-2017 improvement scale and no collar adjustment. The fair value of plan assets for the U.S. pension plans at December 31, 2019 and 2018 was $1.9 billion and $1.8 billion , respectively, while the fair value of plan assets at December 31, 2019 and 2018 for non-U.S. pension plans was $820 million and $713 million , respectively. At December 31, 2019 and 2018 , the expected weighted-average long-term rate of return on U.S. pension plan assets was 7.37 percent and 7.43 percent, respectively. The expected weighted-average long-term rate of return on non-U.S. pension plans assets was 4.26 percent and 4.49 percent at December 31, 2019 and 2018 , respectively.

Non-U.S. primarily consists of annuity contracts and alternative investments. Investment Strategy Eastman's investment strategy for its defined benefit pension plans is to maximize the long-term rate of return on plan assets within an acceptable level of risk in order to meet or exceed the plan's actuarially assumed long-term rate of return and to minimize the cost of providing pension benefits. A periodic asset/liability study is conducted in order to assist in the determination and, if necessary, modification of the appropriate long-term investment policy for the plan. The investment policy establishes a target allocation range for each asset class and the fund is managed within those ranges. The plans use a number of investment approaches including investments in equity, real estate, and fixed income funds in which the underlying securities are marketable in order to achieve this target allocation. The plans also invest in private equity and other funds. Diversification is created through investments across various asset classes, geographies, fund managers, and individual securities. This investment process is designed to provide for a well-diversified portfolio with no significant concentration of risk. The investment process is monitored by an investment committee that includes senior management. Eastman's investment strategy for its VEBA trust is to invest in intermediate-term, well diversified, high quality investment instruments, with a primary objective of capital preservation. The expected rate of return for all plans was determined primarily by modeling the expected long-term rates of return for the categories of investments held by the plans and the targeted allocation percentage against various potential economic scenarios. The Company made no contributions to its U.S. defined benefit pension plans in 2019 or 2018 . For 2020 calendar year, there are no minimum required cash contributions for the U.S. defined benefit pension plans under the Employee Retirement Income Security Act of 1974, as amended, and the Internal Revenue Code of 1986, as amended. The estimated future benefit payments, reflecting expected future service, as appropriate, are as follows: Pension Plans Postretirement Benefit Plans (Dollars in millions) U.S. Non-U.S. 2020 $ 197 $ 31 $ 57 2021 161 30 57 2022 156 31 53 2023 151 34 47 2024 151 38 47 2025-2029 686 210 223

LEASES AND OTHER COMMITMENTS LEASES AND OTHER COMMITMENTS	Dec. 31, 2019
Leases [Abstract]
Commitments Disclosure [Text Block]	LEASES AND OTHER COMMITMENTS Leases On January 1, 2019, Eastman adopted ASU 2016-02 Leases and related releases under the modified retrospective optional transition method such that prior period financial statements have not been adjusted to reflect the impact of the new standard. The new standard establishes two types of leases: finance and operating. Both types of leases have associated right-to-use assets and lease liabilities that have been valued at the present value of the lease payments and recognized on the Consolidated Statements of Financial Position which did not result in an impact to retained earnings. The discount rate used in the measurement of a right-to-use asset and lease liability is the rate implicit in the lease whenever that rate is readily determinable. If the rate implicit in the lease is not readily determinable, the collateralized incremental borrowing rate is used. Upon adoption, the Company elected the practical expedient package wherein: expired or existing contracts were not reassessed as to whether these contracts are or contained a lease; expired or existing contracts were not reassessed for operating or financing classification; and initial direct costs for existing leases were not reassessed. The Company also elected the practical expedient not to assess whether existing or expired land easements that were not previously accounted for under the prior standard are or contain a lease. Lastly, the Company elected the accounting policy not to apply the recognition and measurement requirements to short-term leases with a term of 12 months or less that do not include a bargain purchase option. The Company has operating leases, as a lessee, with customary terms that do not include: significant variable lease payments; significant reasonably certain extensions or options required to be included in the lease term; restrictions; or other covenants for real property, rolling stock, and machinery and equipment. Real property leases primarily consist of office space and rolling stock leases primarily for railcars and fleet vehicles. At December 31, 2019 , operating right-to-use assets of $197 million are included as a part of "Other noncurrent assets" in the Consolidated Statements of Financial Position and includes $8 million of assets previously classified as lease intangibles. Operating lease liabilities are included as a part of "Payables and other current liabilities" and "Other long-term liabilities" in the Consolidated Statements of Financial Position. As of December 31, 2019 , maturities of operating lease liabilities is provided below: (Dollars in millions) Operating lease liabilities 2020 $ 62 2021 49 2022 38 2023 25 2024 14 2025 and beyond 30 Total lease payments 218 Less: amounts of lease payments representing interest 22 Present value of future lease payments 196 Less: current obligations under leases 55 Long-term lease obligations $ 141 There have been no material changes to the future minimum lease payments as of December 31, 2018 as accounted for under the previous lease standard. The Company has operating leases, primarily leases for railcars, with terms that require the Company to guarantee a portion of the residual value of the leased assets upon termination of the lease that will expire beginning in first quarter 2020. Residual guarantee payments that become probable and estimable are recognized as rent expense over the remaining life of the applicable lease. Management's current expectation is that the likelihood of material residual guarantee payments is remote. Lease costs during the period and other information is provided below: For year ended (Dollars in millions) December 31, 2019 Lease costs: Operating lease costs $ 70 Short-term lease costs 40 Sublease income (2 ) Total $ 108 Other operating lease information: Cash paid for amounts included in the measurement of lease liabilities $ 72 Right-to-use assets obtained in exchange for new lease liabilities 54 Weighted-average remaining lease term, in years 5 Weighted-average discount rate 4.0 % Debt and Other Commitments Eastman's obligations are summarized in the following table. (Dollars in millions) Payments Due for Period Debt Securities Credit Facilities and Other Interest Payable Purchase Obligations Operating Leases Other Liabilities Total 2020 $ — $ 171 $ 173 $ 181 $ 62 $ 241 $ 828 2021 483 — 186 156 49 81 955 2022 741 — 175 102 38 87 1,143 2023 840 — 156 91 25 87 1,199 2024 240 — 137 100 14 89 580 2025 and beyond 3,307 — 1,414 1,967 30 1,106 7,824 Total $ 5,611 $ 171 $ 2,241 $ 2,597 $ 218 $ 1,691 $ 12,529 Estimated future payments of debt securities assumes the repayment of principal upon stated maturity, and actual amounts and the timing of such payments may differ materially due to repayment or other changes in the terms of such debt prior to maturity. Eastman had various purchase obligations at December 31, 2019 totaling approximately $2.6 billion over a period of approximately 30 years for materials, supplies, and energy incident to the ordinary conduct of business. Amounts in other liabilities represent the current estimated cash payments required to be made by the Company primarily for pension and other postretirement benefits, environmental loss contingency reserves, accrued compensation benefits, uncertain tax liabilities, and commodity and foreign exchange hedging in the periods indicated. Due to uncertainties in the timing of the effective settlement of tax positions with respect to taxing authorities, management is unable to determine the timing of payments related to uncertain tax liabilities and these amounts are included in the "2025 and beyond" line item. Guarantees and claims also arise during the ordinary course of business from relationships with customers, suppliers, joint venture partners, and other parties when the Company undertakes an obligation to guarantee the performance of others if specified triggering events occur. Non-performance under a contract could trigger an obligation of the Company. The Company's current other guarantees include guarantees relating to intellectual property, environmental matters, and other indemnifications and have arisen through the normal course of business. The ultimate effect on future financial results is not subject to reasonable estimation because considerable uncertainty exists as to the final outcome of these claims, if they were to occur. These other guarantees have terms up to 30 years with maximum potential future payments of approximately $35 million in the aggregate, with none of these guarantees being individually significant to the Company's operating results, financial position, or liquidity. Management's current expectation is that future payment or performance related to non-performance under other guarantees is remote.

ENVIRONMENTAL MATTERS

ENVIRONMENTAL MATTERS	Dec. 31, 2019
Environmental Matters [Abstract]
ENVIRONMENTAL MATTERS	ENVIRONMENTAL MATTERS AND ASSET RETIREMENT OBLIGATIONS Certain Eastman manufacturing facilities generate hazardous and nonhazardous wastes, the treatment, storage, transportation, and disposal of which are regulated by various governmental agencies. In connection with the cleanup of various hazardous waste sites, the Company, along with many other entities, has been designated a potentially responsible party ("PRP") by the U.S. Environmental Protection Agency under the Comprehensive Environmental Response, Compensation and Liability Act, which potentially subjects PRPs to joint and several liability for certain cleanup costs. In addition, the Company will incur costs for environmental remediation and closure and post-closure under the federal Resource Conservation and Recovery Act. Reserves for environmental contingencies have been established in accordance with Eastman's policies described in Note 1, "Significant Accounting Policies" . The resolution of uncertainties related to environmental matters may have a material adverse effect on the Company's consolidated results of operations in the period recognized. However, because of the availability of legal defenses, the Company's preliminary assessment of actions that may be required, and the extended period of time that the obligations are expected to be satisfied, management does not believe that the Company's liability for these environmental matters, individually or in the aggregate, will have a material adverse effect on the Company's future liquidity or financial condition. The Company's total reserve for environmental loss contingencies was $287 million and $296 million at December 31, 2019 and December 31, 2018 , respectively. Environmental Remediation and Environmental Asset Retirement Obligations The Company's total environmental reserve that management believes to be probable and reasonably estimable for environmental contingencies, including remediation costs and asset retirement obligations, is included as part of "Payables and other current liabilities" and "Other long-term liabilities" in the Consolidated Statements of Financial Position as follows: (Dollars in millions) December 31, 2019 2018 Environmental contingent liabilities, current $ 20 $ 25 Environmental contingent liabilities, long-term 267 271 Total $ 287 $ 296 Environmental Remediation Estimated future environmental expenditures for undiscounted remediation costs ranged from the best estimate or minimum of $260 million to the maximum of $487 million and from the best estimate or minimum of $271 million to the maximum of $508 million at December 31, 2019 and December 31, 2018 , respectively. The best estimate or minimum estimated future environmental expenditures are considered to be probable and reasonably estimable and include the amounts recognized at both December 31, 2019 and December 31, 2018 . Costs of certain remediation projects included in the environmental reserve are subject to a cost-sharing arrangement with Monsanto Company ("Monsanto") under the provisions of the Amended and Restated Settlement Agreement effective February 28, 2008 (the "Effective Date"), into which Solutia entered with Monsanto upon its emergence from bankruptcy (the "Monsanto Settlement Agreement"). Under the provisions of the Monsanto Settlement Agreement, Solutia, which became a wholly-owned subsidiary of Eastman on July 2, 2012, shares responsibility with Monsanto for remediation at certain locations outside of the boundaries of plant sites in Anniston, Alabama and Sauget, Illinois (the "Shared Sites"). Solutia is responsible for the funding of environmental liabilities at the Shared Sites up to a total of $325 million from the Effective Date. If remediation costs for the Shared Sites exceed this amount, such costs will thereafter be shared equally between Solutia and Monsanto. Including payments by Solutia prior to its acquisition by Eastman, $99 million had been paid for costs at the Shared Sites as of December 31, 2019 . As of December 31, 2019 , an additional $197 million has been recognized for estimated future remediation costs at the Shared Sites, over a period of approximately 30 years. Reserves for environmental remediation include liabilities expected to be paid within approximately 30 years . The amounts charged to pre-tax earnings for environmental remediation and related charges are included within "Cost of sales" in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings. Changes in the reserves for environmental remediation liabilities for twelve months ended 2019 are summarized below: (Dollars in millions) Environmental Remediation Liabilities Balance at December 31, 2017 $ 280 Changes in estimates recognized in earnings and other 7 Cash reductions (16 ) Balance at December 31, 2018 271 Changes in estimates recognized in earnings and other 4 Cash reductions (15 ) Balance at December 31, 2019 $ 260 Environmental Asset Retirement Obligations An asset retirement obligation is an obligation for the retirement of a tangible long-lived asset that is incurred upon the acquisition, construction, development, or normal operation of that long-lived asset. Eastman recognizes a sset retirement obligations in the period in which they are incurred if a reasonable estimate of fair value can be made. The asset retirement obligations are discounted to expected present value and subsequently adjusted for changes in fair value. The associated estimated asset retirement costs are capitalized as part of the carrying value of the long-lived assets and depreciated over their useful life. Environmental asset retirement obligations consist of primarily closure and post-closure costs. For sites that have environmental asset retirement obligations, the best estimate recognized to date for these environmental asset retirement obligation costs was $27 million and $25 million at December 31, 2019 and December 31, 2018 , respectively. Other Environmental costs are capitalized if they extend the life of the related property, increase its capacity, or mitigate the possibility of future contamination. The cost of operating and maintaining environmental control facilities is charged to expense as incurred. Eastman's cash expenditures related to environmental protection and improvement were $244 million , $274 million , and $257 million in 2019 , 2018 , and 2017 , respectively, and include operating costs associated with environmental protection equipment and facilities, engineering costs, and construction costs. The cash expenditures above include environmental capital expenditures of approximately $27 million , $44 million , and $38 million in 2019 , 2018 , and 2017 , respectively. The Company also has contractual asset retirement obligations not associated with environmental liabilities. Eastman's non-environmental asset retirement obligations are primarily associated with the future closure of leased manufacturing assets at Pace, Florida and Oulu, Finland. These recognized non-environmental asset retirement obligations were $48 million and $46 million at December 31, 2019 and December 31, 2018 , respectively, and are included as part of "Other long-term liabilities" in the Consolidated Statements of Financial Position.

Loss Contingency, Information about Litigation Matters [Abstract]
LEGAL MATTERS	LEGAL MATTERS From time to time, Eastman and its operations are parties to, or targets of, lawsuits, claims, investigations and proceedings, including product liability, personal injury, asbestos, patent and intellectual property, commercial, contract, environmental, antitrust, health and safety, and employment matters, which are handled and defended in the ordinary course of business. While the Company is unable to predict the outcome of these matters, it does not believe, based upon currently available facts, that the ultimate resolution of any such pending matters will have a material adverse effect on its overall financial condition, results of operations, or cash flows.

(2) Share-based compensation expense is the fair value of share-based awards. (3) On January 1, 2018, the Company adopted new accounting standards for revenue recognition and derivatives and hedging, which resulted in increases to beginning retained earnings of $53 million and $2 million , respectively. The Company also adopted a new accounting standard for income taxes, which resulted in a decrease to beginning retained earnings of $39 million . (4) Additional paid-in capital includes value of shares withheld for employees' taxes on vesting of share-based compensation awards. (5) On January 1, 2019, the Company adopted a new accounting standard for reporting comprehensive income, which resulted in a reclassification of stranded tax effects from the Tax Reform Act from AOCI to retained earnings. See Note 1, "Significant Accounting Policies" , for additional information. Eastman is authorized to issue 400 million shares of all classes of stock, of which 50 million may be preferred stock, par value $0.01 per share, and 350 million may be common stock, par value $0.01 per share. The Company declared dividends per share of $2.52 in 2019 , $2.30 in 2018 , and $2.09 in 2017 . The Company established a benefit security trust in 1997 to provide a degree of financial security for unfunded obligations under certain unfunded plans and contributed to the trust a warrant to purchase up to 6 million shares of common stock of the Company for par value. The warrant, which remains outstanding, is exercisable by the trustee if the Company does not meet certain funding obligations, which obligations would be triggered by certain occurrences, including a change in control or potential change in control, as defined, or failure by the Company to meet its payment obligations under certain covered unfunded plans. Such warrant is excluded from the computation of diluted EPS because the conditions upon which the warrant becomes exercisable have not been met. The additions to paid-in capital in 2019 , 2018 , and 2017 are primarily for compensation expense of equity awards and employee stock option exercises. In February 2014, the Company's Board of Directors authorized repurchase of up to $1 billion of the Company's outstanding common stock. The Company completed the $1 billion repurchase authorization in May 2018, acquiring a total of 12,215,950 shares. In February 2018, the Company's Board of Directors authorized the repurchase of up to $2 billion of the Company's outstanding common stock at such times, in such amounts, and on such terms, as determined by management to be in the best interest of the Company. As of December 31, 2019 , a total of 6,753,164 shares have been repurchased under this authorization for a total of $573 million . During 2019 , the Company repurchased 4,282,409 shares of common stock for a cost of approximately $325 million . During 2018 , the Company repurchased 3,959,878 shares of common stock for a cost of approximately $400 million . During 2017 , the Company repurchased 4,184,637 shares of common stock for a cost of approximately $350 million . The Company's charitable foundation held 50,798 issued and outstanding shares of the Company's common stock at December 31, 2019 , 2018 , and 2017 which are included in treasury stock in the Consolidated Statements of Financial Position and excluded from calculations of diluted EPS. The following table sets forth the computation of basic and diluted EPS: For years ended December 31, (In millions, except per share amounts) 2019 2018 2017 Numerator Net earnings attributable to Eastman $ 759 $ 1,080 $ 1,384 Denominator Weighted average shares used for basic EPS 137.4 141.2 144.8 Dilutive effect of stock options and other award plans 1.1 1.7 1.3 Weighted average shares used for diluted EPS 138.5 142.9 146.1 EPS (1) Basic $ 5.52 $ 7.65 $ 9.56 Diluted $ 5.48 $ 7.56 $ 9.47 (1) EPS is calculated using whole dollars and shares. Shares underlying stock options excluded from the 2019 , 2018 , and 2017 calculations of diluted EPS were 2,183,875 , 619,706 , and 204,978 , respectively, because the grant price of these options was greater than the average market price of the Company's common stock and the effect of including them in the calculation of diluted EPS would have been antidilutive. Shares of common stock issued, including shares held in treasury, are presented below: For years ended December 31, 2019 2018 2017 Balance at beginning of year 219,140,523 218,369,992 217,707,600 Issued for employee compensation and benefit plans 498,123 770,531 662,392 Balance at end of year 219,638,646 219,140,523 218,369,992 Accumulated Other Comprehensive Income (Loss) (Dollars in millions) Cumulative Translation Adjustment Benefit Plans Unrecognized Prior Service Credits Unrealized Gains (Losses) on Cash Flow Hedges Unrealized Losses on Investments Accumulated Other Comprehensive Income (Loss) Balance at December 31, 2017 $ (296 ) $ 136 $ (48 ) $ (1 ) $ (209 ) Period change (13 ) (30 ) 7 — (36 ) Balance at December 31, 2018 (309 ) 106 (41 ) (1 ) (245 ) Period change (1) 45 — (14 ) — 31 Balance at December 31, 2019 $ (264 ) $ 106 $ (55 ) $ (1 ) $ (214 ) (1) Benefit plans unrecognized prior service credits includes $29 million reclassification of stranded tax expense from AOCI to retained earnings and unrealized gains (losses) on derivative instruments includes $9 million reclassification of stranded tax benefit from AOCI to retained earnings. See Note 1, "Significant Accounting Policies" , for additional information. Amounts of other comprehensive income (loss) are presented net of applicable taxes.

SHARE-BASED COMPENSATION PLANS AND AWARDS	Dec. 31, 2019
Share-based Payment Arrangement [Abstract]
SHARE-BASED COMPENSATION PLANS AND AWARDS	SHARE-BASED COMPENSATION PLANS AND AWARDS 2017 Omnibus Stock Compensation Plan Eastman's 2017 Omnibus Stock Compensation Plan ("2017 Omnibus Plan") was approved by stockholders at the May 4, 2017 Annual Meeting of Stockholders and shall remain in effect until its fifth anniversary. The 2017 Omnibus Plan authorizes the Compensation and Management Development Committee of the Board of Directors to grant awards, designate participants, determine the types and numbers of awards, determine the terms and conditions of awards and determine the form of award settlement. Under the 2017 Omnibus Plan, the aggregate number of shares reserved and available for issuance is 10 million , which consist of shares not previously authorized for issuance under any other plan. The number of shares covered by an award is counted against this share reserve as of the grant date of the award. Shares covered by full value awards (e.g. performance shares and restricted stock awards) are counted against the total number of shares available for issuance or delivery under the plan as 2.5 shares for every one share covered by the award. Any stock distributed pursuant to an award may consist of, in whole or in part, authorized and unissued stock, treasury stock, or stock purchased on the open market. Under the 2017 Omnibus Plan and previous plans, the forms of awards have included restricted stock and restricted stock units, stock options, stock appreciation rights ("SARs"), and performance shares. The 2017 Omnibus Plan is flexible as to the number of specific forms of awards, but provides that stock options and SARs are to be granted at an exercise price not less than 100 percent of the per share fair market value on the date of the grant . Director Stock Compensation Subplan Eastman's 2018 Director Stock Compensation Subplan ("Directors' Subplan"), a component of the 2017 Omnibus Plan, remains in effect until terminated by the Board of Directors or the earlier termination of the 2017 Omnibus Plan. The Directors' Subplan provides for structured awards of restricted shares to non-employee members of the Board of Directors. Restricted shares awarded under the Directors' Subplan are subject to the same terms and conditions of the 2017 Omnibus Plan. The Directors' Subplan does not constitute a separate source of shares for grant of equity awards and all shares awarded are part of the 10 million shares authorized under the 2017 Omnibus Plan. Shares of restricted stock are granted on the first day of a non-employee director's initial term of service and shares of restricted stock are granted each year to each non-employee director on the date of the annual meeting of stockholders. It has been the Company's practice to issue new shares rather than treasury shares for equity awards for compensation plans, including the 2017 Omnibus Plan and the Directors' Subplan, that require settlement by the issuance of common stock and to withhold or accept back shares awarded to cover the related income tax obligations of employee participants. Shares of unrestricted common stock owned by non-employee directors are not eligible to be withheld or acquired to satisfy the withholding obligation related to their income taxes. Shares of unrestricted common stock owned by specified senior management level employees are accepted by the Company to pay the exercise price of stock options in accordance with the terms and conditions of their awards. Compensation Expense For 2019 , 2018 , and 2017 , total share-based compensation expense (before tax) of approximately $59 million , $64 million , and $52 million , respectively, was recognized in "Selling, general and administrative expense" in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings for all share-based awards of which approximately $9 million , $9 million , and $8 million , respectively, related to stock options. The compensation expense is recognized over the substantive vesting period, which may be a shorter time period than the stated vesting period for qualifying termination eligible employees as defined in the forms of award notice. Approximately $3 million for both 2019 and 2018 and $2 million for 2017 of stock option compensation expense was recognized each year due to qualifying termination eligibility preceding the requisite vesting period. Stock Option Awards Options have been granted on an annual basis by the Compensation and Management Development Committee of the Board of Directors under the 2017 Omnibus Plan and predecessor plans to employees. Option awards have an exercise price equal to the closing price of the Company's stock on the date of grant. The term of options is 10 years with vesting periods that vary up to three years . Vesting usually occurs ratably over the vesting period or at the end of the vesting period. The Company utilizes the Black Scholes Merton option valuation model which relies on certain assumptions to estimate an option's fair value. The weighted average assumptions used in the determination of fair value for stock options awarded in 2019 , 2018 , and 2017 are provided in the table below: Assumptions 2019 2018 2017 Expected volatility rate 19.80% 19.03% 20.45% Expected dividend yield 2.51% 2.48% 2.64% Average risk-free interest rate 2.44% 2.61% 1.91% Expected term years 5.7 5.1 5.0 The volatility rate of grants is derived from historical Company common stock price volatility over the same time period as the expected term of each stock option award. The volatility rate is derived by mathematical formula utilizing the weekly high closing stock price data over the expected term. The expected dividend yield is calculated using the Company's average of the last four quarterly dividend yields . The average risk-free interest rate is derived from United States Department of Treasury published interest rates of daily yield curves for the same time period as the expected term. The weighted average expected term reflects the analysis of historical share-based award transactions and includes option swap and reload grants which may have much shorter remaining expected terms than new option grants. A summary of the activity of the Company's stock option awards for 2019 , 2018 , and 2017 is presented below: 2019 2018 2017 Options Weighted-Average Exercise Price Options Weighted-Average Exercise Price Options Weighted-Average Exercise Price Outstanding at beginning of year 2,905,600 $ 79 2,614,100 $ 70 2,363,700 $ 61 Granted 786,000 81 619,700 104 745,800 80 Exercised (135,700 ) 67 (323,000 ) 55 (489,300 ) 44 Cancelled, forfeited, or expired (76,600 ) 88 (5,200 ) 78 (6,100 ) 74 Outstanding at end of year 3,479,300 $ 80 2,905,600 $ 79 2,614,100 $ 70 Options exercisable at year-end 2,077,600 1,606,800 1,335,500 Available for grant at end of year 6,085,857 8,174,614 9,943,033 The following table provides the remaining contractual term and weighted average exercise prices of stock options outstanding and exercisable at December 31, 2019 : Options Outstanding Options Exercisable Range of Exercise Prices Number Outstanding at December 31, 2019 Weighted-Average Remaining Contractual Life (Years) Weighted-Average Exercise Price Number Exercisable at December 31, 2019 Weighted-Average Exercise Price $38-$50 176,700 1.5 $ 39 176,700 $ 39 $51-$73 720,500 5.9 67 625,100 66 $74-$89 1,985,100 7.1 81 1,076,800 79 $90-$104 597,000 8.2 104 199,000 — 104 3,479,300 6.8 $ 80 2,077,600 $ 74 The range of exercise prices of options outstanding at December 31, 2019 is approximately $38 to $104 per share. The aggregate intrinsic value of total options outstanding and total options exercisable at December 31, 2019 is $18 million and $17 million , respectively. Intrinsic value is the amount by which the closing market price of the stock at December 31, 2019 exceeds the exercise price of the option grants. The weighted average remaining contractual life of all exercisable options at December 31, 2019 is 5.5 years. The weighted average fair value of options granted during 2019 , 2018 , and 2017 was $13.12 , $15.90 , and $11.79 , respectively. The total intrinsic value of options exercised during the years ended December 31, 2019 , 2018 , and 2017 , was $2 million , $15 million , and $19 million , respectively. Cash proceeds received by the Company from option exercises totaled $9 million and the related tax benefit was de minimis for 2019 . Cash proceeds received by the Company from option exercises and the related tax benefit totaled $18 million and $3 million , respectively, for 2018 and $22 million and $5 million , respectively, for 2017 . The total fair value of shares vested during the years ended December 31, 2019 , 2018 , and 2017 was $8 million , $7 million , and $6 million , respectively. A summary of the changes in the Company's nonvested options during the year ended December 31, 2019 is presented below: Nonvested Options Number of Options Weighted-Average Grant Date Fair Value Nonvested at January 1, 2019 1,298,800 $13.63 Granted 786,000 $13.12 Vested (608,200 ) $12.89 Cancelled, forfeited, or expired (74,900 ) $13.43 Nonvested options at December 31, 2019 1,401,700 $13.68 For nonvested options at December 31, 2019 , approximately $5 million in compensation expense will be recognized over the next two years . Other Share-Based Compensation Awards In addition to stock option awards, Eastman has awarded long-term performance share awards, restricted stock awards, and SARs. The long-term performance share awards are based upon actual return on capital compared to a target return on capital and total stockholder return compared to a peer group ranking by total stockholder return over a three year performance period. The awards are valued using a Monte Carlo Simulation based model and vest pro-rata over the three year performance period. The number of long-term performance award target shares granted for the 2019-2021, 2018-2020, and 2017-2019 periods were 412 thousand , 310 thousand , and 357 thousand , respectively. The target shares granted are assumed to be 100 percent. At the end of the three-year performance period, the actual number of shares awarded can range from zero percent to 250 percent of the target shares granted based on the award notice. The number of restricted stock awards granted during 2019 , 2018 , and 2017 were 189 thousand , 160 thousand , and 172 thousand , respectively. The fair value of a restricted stock award is equal to the closing stock price of the Company's stock on the date of grant and normally vests over a period of three years. The recognized compensation expense before tax for these other share-based awards in the years ended December 31, 2019 , 2018 , and 2017 was approximately $50 million , $55 million , and $44 million , respectively. The unrecognized compensation expense before tax for these same type awards at December 31, 2019 was approximately $55 million and will be recognized primarily over a period of two years .

SIGNIFICANT ACCOUNTING POLICI_2

SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
SIGNIFICANT ACCOUNTING POLICIES (Policies)	Dec. 31, 2019
Accounting Policies [Abstract]
Financial Statement Presentation	Financial Statement Presentation The consolidated financial statements of Eastman Chemical Company ("Eastman" or the "Company") and subsidiaries are prepared in conformity with accounting principles generally accepted ("GAAP") in the United States and of necessity include some amounts that are based upon management estimates and judgments. Future actual results could differ from such current estimates. The 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 in minority-owned companies 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 consolidated financial statements and accompanying footnotes to conform to current period presentation.
New Accounting Pronouncements	Recently Adopted Accounting Standards Accounting Standards Update ("ASU") 2016-02 Leases: On January 1, 2019, Eastman adopted this standard, and related releases, under the modified retrospective optional transition method such that prior period financial statements have not been adjusted to reflect the impact of the new standard and adoption did not result in an impact to retained earnings. Upon adoption, operating right-to-use assets and lease liabilities were $219 million . The new standard establishes two types of leases: finance and operating. Both finance and operating leases have associated right-to-use assets and lease liabilities that have been valued at the present value of the lease payments and recognized on the Consolidated Statement of Financial Position. For further information, see Note 11, "Leases and Other Commitments" . ASU 2018-02 Income Statement - Reporting Comprehensive Income: On January 1, 2019, Eastman adopted this standard in the current period resulting in the reclassification of $20 million of stranded tax expense from accumulated other comprehensive income (loss) ("AOCI") to retained earnings as a result of the 2017 Tax Cuts and Jobs Act ("Tax Reform Act"). The amount of the reclassification is the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts and related valuation allowances related to items remaining in AOCI. ASU 2018-15 Internal-Use Software - Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract: On January 1, 2019, Eastman adopted this standard prospectively which did not result in a material impact on the Company's financial statements and related disclosures. ASU 2018-16 Derivatives and Hedging - Inclusion of the Secured Overnight Financing Rate ("SOFR") Overnight Index Swap ("OIS") Rate as a Benchmark Interest Rate for Hedge Accounting Purposes: On January 1, 2019, Eastman adopted this standard prospectively for qualifying new or redesignated hedging relationships. Management does not expect the adoption of this standard will materially impact the Company's financial statements and related disclosures. Accounting Standards Issued But Not Adopted as of December 31, 2019 ASU 2016-13 Financial Instruments - Credit Losses: In June 2016, the Financial Accounting Standards Board ("FASB") issued this standard relating to credit losses and subsequent related releases. The amendments require a financial asset (including trade receivables) to be presented at the net amount expected to be collected through the use of allowances for credit losses valuation account. The income statement will reflect the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. This standard is effective for annual reporting periods beginning after December 15, 2019. The new standard application is mixed among the various elements that include modified retrospective and prospective transition methods. Management does not expect that changes in its accounting required by the new standard will materially impact the Company's financial statements and related disclosures. ASU 2018-13 Fair Value Measurement - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement: In August 2018, the FASB issued this update as a part of its disclosure framework project to improve the effectiveness of disclosures in the notes to financial statements. The primary changes applicable to Eastman in this update are the disclosures of fair value levels, assessment thereof, and transfers between those levels. This standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Certain disclosure amendments are to be applied prospectively for only the most recent interim or annual period presented, while other amendments are to be applied retrospectively to all periods presented. Management does not expect that changes required by the new standard will materially impact the Company's related disclosures. ASU 2018-14 Retirement Benefits - Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans: In August 2018, the FASB issued this update as a part of its disclosure framework project to improve the effectiveness of disclosures in the notes to financial statements. The primary change impacting Eastman is the addition of disclosures related to significant gains and losses related to changes in the benefit obligation for the period and weighted-average interest crediting rates for cash balance plans. This standard is effective for fiscal years ending after December 15, 2020 and early adoption is permitted. Upon adoption, this update is to be applied on a retrospective basis to all periods presented. Management does not expect that changes required by the new standard will materially impact the Company's related disclosures. ASU 2018-18 Collaborative Arrangements - Clarifying the Interaction between Topic 808 (Collaborative Arrangements) and Topic 606 (Revenue from Contracts with Customers): In November 2018, the FASB issued clarification in regards to which contracts are accounted for under Topic 808 and Topic 606 as well as alignment of guidance between the two pronouncements. This standard is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Upon adoption, this update is to be applied retrospectively to the date of initial application of Topic 606. Management is currently evaluating the impact on the Company's financial statements and related disclosures. ASU 2019-01 Leases - Codification Improvements: In March 2019, the FASB issued this update in response to stakeholder inquiries regarding the new leasing standard. This standard is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Upon adoption, this update is to be applied as of the adoption date and under the same transition methodology of ASU 2016-02 Leases . Management is currently evaluating the impact on the Company's financial statements and related disclosures. ASU 2019-12 Income Taxes - Simplifying the Accounting for Income Taxes : In December 2019, the FASB issued this update as part of its initiative to reduce complexity in accounting standards which removes certain exceptions and provides simplification to specific tax items. This standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. Adoption methods vary based on the specific items impacted. Management is currently evaluating the impact on the Company's financial statements and related disclosures.
Revenue Recognition and Customer Incentives	Revenue Recognition On January 1, 2018, Eastman adopted ASU 2014-09 Revenue Recognition (ASC 606) under the modified retrospective method, such that revenue for all periods prior to January 1, 2018 continue to be reported under the previous standard, which resulted in an increase to retained earnings of $53 million after tax for products shipped but not delivered as of December 31, 2017. Eastman recognizes revenue when performance obligations of the sale are satisfied. Eastman sells to customers through master sales agreements or standalone purchase orders. The majority of the Company's terms of sale have a single performance obligation to transfer products. Accordingly, the Company recognizes revenue when control has been transferred to the customer, generally at the time of shipment of products. Eastman accounts for shipping and handling as activities to fulfill the promise to transfer the good and does not allocate revenue to those activities. All related shipping and handling costs are recognized at the time of shipment. Amounts collected for sales or other similar taxes are presented net of the related tax expense rather than presenting them as additional revenue. The incremental cost of obtaining a sales contract is recognized as a selling expense when incurred given the potential amortization period for such an asset is one year or less. The possible existence of a significant financing component within a sales contract is ignored when the time between cash collection and performance is less than one year. Finally, the Company does not disclose any unfulfilled obligations as customer purchase order commitments have an original expected duration of one year or less and no consideration from customers is excluded from the transaction price. The timing of Eastman's customer billings does not always match the timing of revenue recognition. When the Company is entitled to bill a customer in advance of the recognition of revenue, a contract liability is recognized. When the Company is not entitled to bill a customer until a period after the related recognition of revenue, a contract asset is recognized. Contract assets represent the Company's right to consideration for the exchange of goods under a contract, but which are not yet billable to a customer for consignment inventory or pursuant to certain shipping terms. Contract liabilities were not material as of December 31, 2019 or December 31, 2018 . Contract assets were $65 million and $62 million as of December 31, 2019 and December 31, 2018 , respectively, and are included as a component of "Miscellaneous receivables" in the Consolidated Statements of Financial Position. For additional information, see Note 19, "Segment and Regional Sales Information" .
Pension and Other Postretirement Benefits	Pension and Other Postretirement Benefits Eastman maintains defined benefit pension plans that provide eligible employees with retirement benefits. Under its other postretirement benefit plans in the U.S., Eastman provides life insurance for eligible retirees hired prior to January 1, 2007. Eastman provides a subsidy for pre-Medicare health care and dental benefits to eligible retirees hired prior to January 1, 2007 that will end on December 31, 2021. Company funding is also provided for eligible Medicare retirees hired prior to January 1, 2007 with a health reimbursement arrangement. The estimated amounts of the costs and obligations related to these benefits reflect the Company's assumptions related to discount rates, expected return on plan assets, rate of compensation increase or decrease for employees, and health care cost trends. The estimated cost of providing plan benefits also depends on demographic assumptions including retirements, mortality, turnover, and plan participation. Eastman's pension and other postretirement benefit plans costs consist of two elements: 1) ongoing costs recognized quarterly, which are comprised of service and interest costs, expected returns on plan assets, and amortization of prior service credits; and 2) mark-to-market ("MTM") gains and losses recognized annually, in the fourth quarter of each year, primarily resulting from changes in actuarial assumptions for discount rates and the differences between actual and expected returns on plan assets. Any interim remeasurements triggered by a curtailment, settlement, or significant plan changes are recognized in the quarter in which such remeasurement event occurs. For additional information, see Note 10, "Retirement Plans" .
Environmental Costs	Environmental Costs Eastman recognizes environmental remediation costs when it is probable that the Company has incurred a liability at a contaminated site and the amount can be reasonably estimated. When a single amount cannot be reasonably estimated but the cost can be estimated within a range, the Company recognizes the minimum undiscounted amount. This undiscounted amount reflects liabilities expected to be paid within approximately 30 years and the Company's assumptions about remediation requirements at the contaminated site, the nature of the remedy, the outcome of discussions with regulatory agencies and other potentially responsible parties at multi-party sites, and the number and financial viability of other potentially responsible parties. Changes in the estimates on which the accruals are based, unanticipated government enforcement action, or changes in health, safety, environmental, and chemical control regulations and testing requirements could result in higher or lower costs. The Company also establishes reserves for closure and post-closure costs associated with the environmental and other assets it maintains. Environmental assets include but are not limited to waste management units, such as landfills, water treatment facilities, and surface impoundments. When these types of assets are constructed or installed, a loss contingency reserve is established for the anticipated future costs associated with the retirement or closure of the asset based on its expected life and the applicable regulatory closure requirements. The Company recognizes the asset retirement obligations in the period in which they are incurred if a reasonable estimate of fair value can be made. The asset retirement obligations are discounted to expected present value and subsequently adjusted for changes in fair value. These future estimated costs are charged to earnings over the estimated useful life of the assets. If the Company changes its estimate of the environmental asset retirement obligation costs or its estimate of the useful lives of these assets, expenses charged to earnings will be impacted. The current portion of accruals for environmental liabilities is included in payables and other current liabilities and the long-term portion is included in other long-term liabilities. These accruals exclude claims for recoveries from insurance companies or other third parties. Environmental costs are capitalized if they extend the life of the related property, increase its capacity, or mitigate or prevent future contamination. The cost of operating and maintaining environmental control facilities is charged to expense as incurred. For additional information see Note 12, "Environmental Matters and Asset Retirement Obligations" .
Share-based Compensation	Share-based Compensation Eastman recognizes compensation expense in the financial statements for stock options and other share-based compensation awards based upon the grant-date fair value over the substantive vesting period. For additional information, see Note 17, "Share-Based Compensation Plans and Awards" .
Restructuring of Operations	Restructuring of Operations Eastman records restructuring charges for costs incurred in connection with consolidation of operations, exited business or product lines, or shutdowns of specific sites that are expected to be substantially completed within twelve months. These restructuring charges are recorded as incurred, and are associated with site closures, legal and environmental matters, demolition, contract terminations, obsolete inventory, or other costs and charges directly related to the restructuring. The Company records severance charges for employee separations when the separation is probable and reasonably estimable. In the event employees are required to perform future service, the Company records severance charges ratably over the remaining service period of those employees. For additional information, see Note 15, "Asset Impairments and Restructuring Charges, Net" .
Income Taxes	Income Taxes The provision for (benefit from) income taxes has been determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for (benefit from) income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of Eastman's assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Provision has been made for income taxes on unremitted earnings of subsidiaries and affiliates, except for subsidiaries in which earnings are deemed to be indefinitely reinvested. The Company recognizes income tax positions that meet the more likely than not threshold and accrues interest related to unrecognized income tax positions which is recorded as a component of the income tax provision. In conjunction with its evaluation of the provisions of the Tax Reform Act, in 2018, the Company made an accounting policy election to account for taxes resulting from the global intangible low-tax income ("GILTI") as a component of the provision for income taxes.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash, time deposits, and readily marketable securities with original maturities of three months or less.
Fair Value Measurements	Fair Value Measurements Eastman records recurring and non-recurring financial assets and liabilities as well as all non-financial assets and liabilities subject to fair value measurement at the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. These fair value principles prioritize valuation inputs across three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company's assumptions used to measure assets and liabilities at fair value. An asset or liability's classification within the various levels is determined based on the lowest level input that is significant to the fair value measurement.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Eastman maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The Company calculates the allowance based on an assessment of the risk in the accounts receivable portfolio. Write-offs are recorded at the time a customer receivable is deemed uncollectible. Allowance for doubtful accounts was $11 million at both December 31, 2019 and 2018 . The Company does not enter into receivables of a long-term nature, also known as financing receivables, in the normal course of business.
Inventories	Inventories Inventories measured by the last-in, first-out ("LIFO") method are valued at the lower of cost or market and inventories measured by the first-in, first-out ("FIFO") method are valued at lower cost or net realizable value. Eastman determines the cost of most raw materials, work in process, and finished goods inventories in the United States and Switzerland by the LIFO method. The cost of all other inventories is determined by the average cost method, which approximates the FIFO method. The Company writes-down its inventories equal to the difference between the carrying value of inventory and the estimated market value or net realizable value based upon assumptions about future demand and market conditions.
Properties	Properties
Depreciation and Amortization	Depreciation and Amortization Depreciation expense is calculated based on historical cost and the estimated useful lives of the assets, generally using the straight-line method. Estimated useful lives for buildings and building equipment generally range from 20 to 50 years. Estimated useful lives generally ranging from 3 to 33 years are applied to machinery and equipment in the following categories: computer software (3 to 5 years); office furniture and fixtures and computer equipment (5 to 10 years); vehicles, railcars, and general machinery and equipment (5 to 20 years); and manufacturing-related improvements (20 to 33 years). Accelerated depreciation is reported when the estimated useful life is shortened and continues to be reported in cost of sales. Amortization expense for definite-lived intangible assets is generally determined using a straight-line method over the estimated useful life of the asset. Amortization expense is reported in cost of sales. For additional information, see Note 4, "Goodwill and Other Intangible Assets" .
Impairment of Long Lived Assets	Impairment of Long-Lived Assets Definite-lived Assets Properties and equipment and definite-lived intangible assets to be held and used by Eastman are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The review of properties and equipment and the review of definite-lived intangible assets is performed at the asset group level, which is the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. If the carrying amount is not considered to be recoverable, an analysis of fair value is triggered. An impairment is recognized for the excess of the carrying amount of the asset over the fair value. Fair value is the price that would be received to sell an asset in an orderly transaction between market participants.
Goodwill and Intangible Assets, Policy	Goodwill Eastman conducts testing of goodwill annually in the fourth quarter or more frequently when events and circumstances indicate an impairment may have occurred. The testing of goodwill is performed at the "reporting unit" level which the Company has determined to be its "components". Components are defined as an operating segment or one level below an operating segment, and in order to be a reporting unit, the component must 1) be a "business" as defined by applicable accounting standards (an integrated set of activities and assets that is capable of being conducted and managed for the purpose of providing a return in the form of dividends, lower costs, or other economic benefits directly to the investors or other owners, members, or participants); 2) have discrete financial information available; and 3) be reviewed regularly by Company operating segment management. The Company aggregates certain components into reporting units based on economic similarities. A reporting unit's goodwill is considered to be impaired when the reporting unit's estimated fair value is less than its carrying value. The Company uses an income approach and applies a discounted cash flow model in testing the carrying value of goodwill for each reporting unit. Key assumptions and estimates used in the Company's 2019 goodwill impairment testing included projections of revenues and earnings before interest and taxes ("EBIT") determined using the Company's annual multi-year strategic plan, the estimated weighted average cost of capital ("WACC") and a projected long-term growth rate. The Company believes these assumptions are consistent with those a hypothetical market participant would use given circumstances that were present at the time the estimates were made. However, actual results and amounts may be significantly different from the Company's estimates. In addition, the use of different estimates or assumptions could result in materially different estimated fair values of reporting units. The WACC is calculated incorporating weighted average returns on debt and equity from market participants. Therefore, changes in the market, which are beyond the control of the Company, may have an impact on future calculations of estimated fair value. Indefinite-lived Intangible Assets Eastman conducts testing of indefinite-lived intangible assets annually in the fourth quarter or more frequently when events and circumstances indicate an impairment may have occurred. The carrying value of an indefinite-lived intangible asset is considered to be impaired when the fair value, as established by appraisal or based on discounted future cash flows of certain related products, is less than the respective carrying value. Indefinite-lived intangible assets, consisting primarily of various tradenames, are tested for potential impairment by comparing the estimated fair value to the carrying amount. The Company uses an income approach, specifically the relief from royalty method, to test indefinite-lived intangible assets. The estimated fair value of tradenames is determined based on an assumed royalty rate savings, discounted by the calculated market participant WACC plus a risk premium. For additional information, see Note 4, "Goodwill and Other Intangible Assets" .
Lessee, Leases [Policy Text Block]	Leases As noted above, On January 1, 2019, Eastman adopted ASU 2016-02 Leases. For accounting policy and elections, see Note 11, "Leases and Other Commitments" .
Investments	Investments The consolidated financial statements include the accounts of Eastman and all its subsidiaries and entities or joint ventures in which a controlling interest is maintained. The Company includes its share of earnings and losses of such investments in "Net earnings attributable to Eastman" and "Comprehensive income attributable to Eastman" located in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings and in "Total equity" located in the Consolidated Statements of Financial Position. Investments in affiliates over which the Company has significant influence but not a controlling interest are carried on the equity basis. Under the equity method of accounting, these investments are included in "Other noncurrent assets" in the Consolidated Statements of Financial Position. The Company includes its share of earnings and losses of such investments in "Other (income) charges, net" located in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings.
Derivative and Non-Derivative Financial Instruments	Derivative and Non-Derivative Financial Instruments Eastman uses derivative and non-derivative instruments to manage its exposure to market risks, such as changes in foreign currency exchange rates, commodity prices, and interest rates. The Company does not enter into derivative transactions for speculative purposes. Counterparties to the derivative contracts are highly rated financial institutions which the Company believes carry minimal risk of nonperformance and the Company diversifies its positions among such counterparties to reduce its exposure to counterparty risk and credit losses. The Company monitors the creditworthiness of its counterparties on an ongoing basis. The Company's derivative instruments are recognized as either assets or liabilities on the Consolidated Statements of Financial Position and measured at fair value. For qualifying derivatives designated as cash flow hedges, the effective portion of the changes in the fair value are reported as a component of AOCI in the Consolidated Statements of Financial Position and recognized in earnings when the hedged items affect earnings. For qualifying derivatives designated as fair value hedges, the effective portion of the changes in the fair value are reported as "Long-term borrowings" on the Consolidated Statements of Financial Position and recognized in earnings when the hedged items affect earnings. For qualifying derivative or non-derivative instruments designated as net investment hedges, the net change in the hedge instrument and item being hedged is reported as a component of "Cumulative translation adjustment" ("CTA") within AOCI located in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings. Any hedge components excluded from the assessment of effectiveness are recognized in earnings, the initial value of the excluded component, using a systematic and rational method over the life of the hedging instrument. Changes in the fair value of nonqualifying derivatives or derivatives that are not designated as hedges, are recognized in current earnings. Hedge accounting will be discontinued prospectively for all hedges that no longer qualify for hedge accounting treatment. Cash flows from derivative instruments designated as hedges are reported in the same category as the cash flows from the items being hedged. For additional information, see Note 9, "Derivative and Non-Derivative Financial Instruments" .
Litigation and Contingent Liabilities	Litigation and Contingent Liabilities Eastman and its operations from time to time are, and in the future may be, parties to or targets of lawsuits, claims, investigations and proceedings, including product liability, personal injury, asbestos, patent and intellectual property, commercial, contract, environmental, antitrust, health and safety, and employment matters, which are handled and defended in the ordinary course of business. The Company accrues a contingent loss liability for such matters when it is probable that a liability has been incurred and the amount can be reasonably estimated. When a single amount cannot be reasonably estimated but the cost can be estimated within a range, the Company accrues the minimum amount. The Company expenses legal costs, including those expected to be incurred in connection with a loss contingency, as incurred.
Off-Balance-Sheet Credit Exposure, Policy [Policy Text Block]	Working Capital Management and Off Balance Sheet Arrangements The Company works with suppliers to optimize payment terms and conditions on accounts payable to enhance timing of working capital and cash flows. As part of these efforts, in 2019, the Company introduced a voluntary supply chain finance program to provide suppliers with the opportunity to sell receivables due from Eastman to a participating financial institution. Eastman's responsibility is limited to making payments on the terms originally negotiated with suppliers, regardless of whether the suppliers sells their receivables to the financial institution. The range of payment terms Eastman negotiates with suppliers are consistent, regardless of whether a supplier participates in the program. All of Eastman's accounts payable and associated payments are reported consistently in the Company's Consolidated Statements of Financial Position and Consolidated Statements of Cash Flows regardless of whether they are associated with a vendor who participates in the program. In 2019 , the Company expanded off balance sheet, uncommitted accounts receivable factoring agreements 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 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 amount of receivables sold in 2019 and 2018 were $857 million and $219 million

[1]	A one-time transition tax of $71 million on deferred foreign income tax is included for 2017.
[2]	Includes a one-time benefit of $517 million primarily due to the remeasurement of certain net deferred tax liabilities using the lower U.S. corporate income tax rate and a one-time $72 million valuation allowance on deferred tax assets for foreign tax credit carryforwards for 2017.
[3]	Includes a one-time net benefit primarily due to the remeasurement of certain net deferred tax liabilities using the lower U.S. corporate income tax rate partially offset by the transition tax on deferred foreign income and changes in the valuation of deferred tax assets associated with tax law changes and the tax impact from intercompany reorganization activities in 2017 and a net incremental adjustment to those amounts under the Tax Reform Act in 2018 and 2019.
[4]	Revised from Note 7, "Income Taxes" , to the Company's 2018 Annual Report on Form 10-K, which reported net operating loss carryforwards as $708 million , valuation allowance as $466 million , and investments as $(274) million .

[1]	U.S. primarily consists of private equity and natural resource and energy related limited partnership investments. Non-U.S. primarily consists of annuity contracts and alternative investmen
[2]	Cash & Cash Equivalents: Funds generally invested in actively managed collective trust funds or interest bearing accounts.
[3]	Debt: The fixed income securities are primarily valued upon a market approach, using matrix pricing and considering a security's relationship to other securities for which quoted prices in an active market may be available, or an income approach, converting future cash flows to a single present value amount. Inputs used in developing fair value estimates include reported trades, broker quotes, benchmark yields, and base spreads.
[4]	Investments Measured at Net Asset Value: The underlying debt and public equity investments in this category are generally held in common trust funds, which are either actively or passively managed investment vehicles, that are valued at the net asset value per unit/share multiplied by the number of units/shares held as of the measurement date. The other alternative investments in this category are valued under the practical expedient method which is based on the most recently reported net asset value provided by the management of each private investment fund, adjusted as appropriate, for any lag between the date of the financial reports and the measurement date.
[5]	Public Equity - United States: Common stock equity securities which are primarily valued using a market approach based on the quoted market prices.
[6]	Other Investments: Primarily consist of insurance contracts which are generally valued using a crediting rate that approximates market returns and investments in underlying securities whose market values are unobservable and determined using pricing models, discounted cash flow methodologies, or similar techniques.
[7]	Primarily consists of insurance contracts.
