- Definition For the entity and the disposal group, cash includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents.

| Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
| Significant Accounting Policies |
NOTE A – SIGNIFICANT ACCOUNTING POLICIES Basis of presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial reporting and Securities and Exchange Commission (SEC) regulations. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. Additionally, certain prior period data, primarily related to discontinued operations, have been reclassified in the Consolidated Financial Statements and accompanying notes to conform to the current period presentation, as further described in this section. These statements omit certain information and footnote disclosures required for complete annual financial statements and, therefore, should be read in conjunction with Ashland Global Holdings Inc.’s (Ashland or the Company) Annual Report on Form 10-K for the fiscal year ended September 30, 2018. Results of operations for the period ended June 30, 2019 are not necessarily indicative of the expected results for the remaining quarters in the fiscal year. On November 15, 2018, Ashland announced that it had signed a definitive agreement to sell substantially all of the assets and liabilities of its Composites segment and Intermediates and Solvents facility in Marl, Germany (Marl facility). This expected divestiture represents a strategic shift in Ashland's business and, in accordance with U.S. GAAP, qualified as a discontinued operation. As a result, the operating results and cash flows related to Composites and the Marl facility have been reflected as discontinued operations in the Statements of Consolidated Comprehensive Income (Loss) and Statements of Condensed Consolidated Cash Flows. The assets and liabilities that are to be sold have met the requirements to be classified within the Condensed Consolidated Balance Sheets under a held for sale designation. See Notes B and C for additional information on this expected divestiture. As a result of classifying the Composites reporting segment as a discontinued operation, Ashland is now comprised of two reportable segments: Specialty Ingredients and Intermediates and Solvents. The financial information reported for Intermediates and Solvents excludes the activity from the Marl facility due to the expected divestiture. Use of estimates, risks and uncertainties The preparation of Ashland’s Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosures of contingent assets and liabilities. Significant items that are subject to such estimates and assumptions include, but are not limited to, long-lived assets (including goodwill and other intangible assets), income taxes and liabilities and receivables associated with asbestos litigation and environmental remediation. Although management bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, actual results could differ significantly from the estimates under different assumptions or conditions. Ashland’s results are affected by domestic and international economic, political, legislative, regulatory and legal actions. Economic conditions, such as recessionary trends, inflation, interest and monetary exchange rates, government fiscal policies and changes in the prices of certain key raw materials, can have a significant effect on operations. While Ashland maintains reserves for anticipated liabilities and carries various levels of insurance, Ashland could be affected by civil, criminal, regulatory or administrative actions, claims or proceedings relating to asbestos, environmental remediation or other matters. New accounting pronouncements A description of new U.S. GAAP accounting standards issued or adopted during the current year is required in interim financial reporting. A detailed listing of new accounting standards relevant to Ashland is included in the Annual Report on Form 10-K for the fiscal year ended September 30, 2018. The following standards relevant to Ashland were either issued or adopted in the current period or will become effective in a subsequent period. Revenue recognition In May 2014, the FASB issued accounting guidance outlining a single comprehensive five step model for entities to use in accounting for revenue arising from contracts with customers (ASC 606 Revenue from Contracts with Customers). The new guidance and subsequent amendments to it superseded most current revenue recognition guidance, in an effort to converge the revenue recognition principles within U.S. GAAP. This new guidance required entities to disclose certain quantitative and qualitative information regarding the nature, amount, timing and uncertainty of qualifying revenue and cash flows arising from contracts with customers. Entities had the option of using a full retrospective or a modified retrospective approach to adopt the new guidance. This guidance became effective for Ashland on October 1, 2018. Ashland formed an implementation team that evaluated the impact of the new standard on the Condensed Consolidated Financial Statements and the adoption method options available as well as the overall impact the new guidance would have on the organization. The assessment process consisted of categorizing Ashland’s revenue streams and reviewing the current internal accounting policies and practices to determine potential differences that could result from applying the requirements of the new standard to revenue contracts. Additional discussions and meetings with each revenue stream team occurred to solicit input, identify potential impacts and appropriate changes to Ashland’s business processes, systems and controls to support the revenue recognition and disclosure requirements under the new standard. Ashland elected to adopt this standard using the modified retrospective approach and determined that the overall impact was not material to the Condensed Consolidated Financial Statements. As a result, no cumulative-effect adjustment was made to retained earnings in the Condensed Consolidated Balance Sheets. Further, there has been no significant change to the manner and timing of recognizing revenue. However, there are significant additional disclosures within the Notes to Condensed Consolidated Financial Statements. ASC 606 requires disclosure of disaggregated revenue into categories that depict the nature of how Ashland's revenue and cash flows are affected by economic factors. Additionally, Ashland is required to disclose additional information related to its revenue recognition policy. See Note O for these additional disclosures. Leases In February 2016, the FASB issued new accounting guidance related to lease transactions. The main objective of this guidance is to increase transparency and comparability among organizations by requiring lessees to recognize assets and liabilities on the balance sheet for the right to use assets and obligations created by leases and to disclose key information about leasing arrangements. The presentation of the Statements of Consolidated Comprehensive Income (Loss) and the Statements of Condensed Consolidated Cash Flows is largely unchanged under this guidance. This guidance retains a distinction between finance leases and operating leases, and the classification criteria for distinguishing between finance leases and operating leases are substantially similar to the classification criteria for distinguishing between capital leases and operating leases in the current accounting literature. The guidance will become effective for Ashland on October 1, 2019 and it will have a significant effect on Ashland’s Condensed Consolidated Balance Sheet and disclosures. In July 2018, the FASB amended this guidance to give entities the option to apply the standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Ashland will utilize this transition method upon adopting the guidance. Ashland will also elect the practical expedient package related to the identification, classification and accounting for initial direct costs whereby prior conclusions do not have to be reassessed for leases that commenced before the effective date. As Ashland will not reassess such conclusions, Ashland does not plan to adopt the practical expedient to use hindsight to determine the likelihood of whether a lease will be extended, terminated or whether a purchase option will be exercised. Ashland’s implementation team is continuing to identify leases, determine policy elections, gather data, implement changes to business processes and controls, and quantifying the impact that this guidance will have within its Condensed Consolidated Financial Statements. Other accounting pronouncements In January 2016, the FASB issued accounting guidance related to the recognition and measurement as well as the presentation and disclosures for certain financial instruments. Most notably, the guidance requires entities to measure equity investments at fair value and to recognize any changes in fair value in net income rather than accumulated other comprehensive income (AOCI). The guidance became effective for Ashland on October 1, 2018 and resulted in Ashland recording a cumulative-effect adjustment to reclassify net after-tax unrealized gains of $34 million on its equity securities from AOCI to retained earnings. In the current period, the adoption of this guidance resulted in a significant impact to net income as Ashland recognized investment gains of $6 million and $3 million for the three and nine months ended June 30, 2019, respectively, within the net interest and other expense caption on the Statement of Consolidated Comprehensive Income (Loss). The impact of this new guidance could continue to have a material impact on Ashland’s Statements of Consolidated Comprehensive Income (Loss) in prospective periods depending on the fluctuations of unrealized gains and losses within the investment securities portfolio. For current and future periods, the changes in fair value of the equity securities will no longer be classified within other comprehensive income under the new guidance. For further information on Ashland’s equity securities, see Note E. In October 2016, the FASB issued new accounting guidance which requires entities to recognize the income tax effects of intercompany transfers of assets other than inventory when the transfer occurs. This guidance eliminates the exception under previous U.S. GAAP that the income tax effects of all intercompany transfers of assets other than inventory be deferred until the assets are sold to a third party or otherwise recovered through use. This guidance became effective for Ashland on October 1, 2018 and was applied using a modified retrospective approach. Consequently, Ashland recorded a cumulative-effect adjustment to reclassify less than $1 million from other current assets and deferred taxes to retained earnings. |

NOTE B – DIVESTITURES Composites and Marl facility On November 15, 2018, Ashland announced that it had signed a definitive agreement to sell its Composites segment and Intermediates and Solvents Marl facility to INEOS Enterprises (INEOS) in a transaction valued at $1.1 billion. Ashland will retain the remaining Intermediates and Solvents facility in Lima, Ohio primarily for its own internal business use. On July 1, 2019 an amendment was signed to exclude certain assets and liabilities related to Ashland’s maleic anhydride business (Maleic business). Under the amendment, Ashland agreed to continue to operate the Maleic business and use commercially reasonable efforts to sell the Maleic business to another purchaser. In connection with any Maleic sale within 18 months of the closing of the Composites and Marl facility sale, excluding Maleic, INEOS will be entitled to the net proceeds, after deduction of the reasonable costs incurred by Ashland; provided that INEOS shall receive no less than $35 million. If Ashland is unable to sell the Maleic business within 18 months of the closing of the Composites and Marl facility sale, excluding Maleic, Ashland has agreed to reimburse $35 million to INEOS. In late July, Ashland and INEOS agreed to certain additional changes to the sale agreement subject to approval by and reflecting continued discussions with the US Federal Trade Commission. As part of the proposed changes, the purchase price has been adjusted to $1.015 billion while Ashland retains the right to the Maleic business, including the retention of any subsequent sale proceeds. The company anticipates that remaining regulatory approvals will be received shortly. Ashland currently expects net proceeds from the sale of Composites and Marl facility to total approximately $0.9 billion and anticipates that the proceeds will be primarily used to reduce outstanding debt and other corporate purposes. The sale of Composites and Marl facility, excluding Maleic, is expected to close by late summer, contingent on certain customary regulatory approvals, standard closing conditions and completion of required employee information and consultation processes. Upon the closing of this transaction, Ashland currently expects to recognize a pre-tax gain in excess of $400 million within the Statements of Consolidated Comprehensive Income (Loss). Since this transaction represents a strategic shift in Ashland’s business and had a major effect on Ashland’s operations and financial results, the operating results and cash flows related to Composites and the Marl facility, including Maleic, have been reflected as discontinued operations in the Statements of Consolidated Comprehensive Income (Loss) and Statements of Condensed Consolidated Cash Flows. See Note C for the results of operations for Composites and the Marl facility, including Maleic, for all periods presented. Certain indirect corporate costs included within the selling, general and administrative expense caption of the Statements of Consolidated Comprehensive Income (Loss) that were previously allocated to the Composites segment and Marl facility do not qualify for classification within discontinued operations and are now reported as selling, general and administrative expense within continuing operations on a consolidated basis and within the Unallocated and other segment. These costs were $10 million and $12 million during the three months ended June 30, 2019 and 2018, respectively, and $33 million and $35 million during the nine months ended June 30, 2019 and 2018, respectively. Ashland is currently implementing plans to eliminate these costs as part of the global restructuring program. Subsequent to the completion of the sale, Ashland expects to provide certain transition services to INEOS Enterprises for a fee. While the transition services are expected to vary in duration depending upon the type of service provided, Ashland expects to reduce costs as the transition services are completed.
Other corporate assets Ashland is currently in the process of pursuing options to divest several corporate assets, primarily related to land and buildings, that are expected to close within the next 12 months. The net property, plant and equipment value related to these sites was $6 million at June 30, 2019 and $9 million at September 30, 2018. During the nine months ended June 30, 2019, a $5 million impairment charge was recorded within the selling, general and administrative expense caption of the Statement of Consolidated Comprehensive Income (Loss) for one of these corporate assets.
Held for sale classification The assets and liabilities of Composites and the Marl facility, including Maleic, along with other corporate asset divestitures for current and prior periods have been reflected as assets and liabilities held for sale. As a result, in accordance with U.S. GAAP standards, depreciation and amortization are no longer being recorded within the Statements of Consolidated Comprehensive Income (Loss) and the Condensed Consolidated Balance Sheets. These assets and liabilities are comprised of the following components:

| Discontinued Operations |
NOTE C– DISCONTINUED OPERATIONS In previous periods, Ashland has divested certain businesses that have qualified as discontinued operations. The operating results from these divested businesses and subsequent adjustments related to ongoing assessments of certain retained liabilities and tax items have been recorded within the discontinued operations caption in the Statements of Consolidated Comprehensive Income (Loss) for all periods presented and are discussed further within this note. As previously described in Note B, Ashland announced that it had signed a definitive agreement on November 15, 2018 to sell its Composites segment and Intermediates and Solvents Marl facility, including Maleic. Ashland determined that this expected divestiture qualified as a discontinued operation, in accordance with U.S. GAAP, since it represents a strategic shift for Ashland and had a major effect on Ashland's operations and financial results. Accordingly, the operating results and cash flows for Composites and the Marl facility have been classified as discontinued operations within the Condensed Consolidated Financial Statements for all periods presented. Ashland completed the distribution of its remaining shares of common stock of Valvoline Inc. on May 12, 2017. Ashland determined that the Valvoline separation qualified as a discontinued operation, in accordance with U.S. GAAP, since it represented a strategic shift for Ashland and had a major effect on Ashland's operations and financial results. Ashland has made subsequent tax adjustments to the discontinued operations caption related to this transaction. During the three and nine months ended June 30, 2019, a $28 million pre-tax gain was recorded upon the completion of a property sale directly relating to Ashland’s Distribution segment sold in 2011. Components of amounts reflected in the Statements of Consolidated Comprehensive Income (Loss) related to discontinued operations are presented in the following table for the three and nine months ended June 30, 2019 and 2018.
The following table presents a reconciliation of the captions within Ashland's Statements of Consolidated Comprehensive Income (Loss) for the income (loss) from discontinued operations attributable to Composites and the Marl facility for the three and nine months ended June 30, 2019 and 2018. Interest expense was allocated to discontinued operations based on Ashland’s mandatory debt prepayments upon the disposition of Composites and the Marl facility, including Maleic.

| Restructuring Activities |
NOTE D – RESTRUCTURING ACTIVITIES Ashland periodically implements company-wide restructuring programs related to acquisitions, divestitures and other cost reduction programs in order to enhance profitability through streamlined operations and an improved overall cost structure. Severance costs During fiscal 2018, Ashland announced and initiated a company-wide cost reduction program as a result of ongoing strategic asset plans and activities. As part of this restructuring program, Ashland announced a voluntary severance offer (VSO) to certain qualifying employees that was formally approved during 2018. Additionally, during fiscal 2018, an involuntary program for employees was also initiated as part of the restructuring program. The VSO and involuntary programs resulted in a severance charge of $36 million during the September 2018 quarter of fiscal 2018. During the three and nine months ended June 30, 2019, these programs resulted in additional severance expense of $3 million and $7 million, respectively, which was primarily recorded within the selling, general and administrative expense caption of the Statement of Consolidated Comprehensive Income (Loss). No charges were incurred for the three or nine months ended June 30, 2018. As of June 30, 2019, the severance reserve for the company-wide restructuring program was $14 million. Facility costs Ashland incurred zero and $8 million of lease abandonment charges during the three and nine months ended June 30, 2019, respectively, due to the exit from certain office facilities in conjunction with the company-wide cost reduction program. Charges of $8 million were incurred for the three or nine months ended June 30, 2018. The costs related to these reserves were recorded within the selling, general and administrative expense caption of the Statements of Consolidated Comprehensive Income (Loss) and are paid over the remaining lease terms. As of June 30, 2019, the reserve for facility costs was $8 million. The following table details at June 30, 2019, the amount of restructuring reserves related to the programs discussed above, and the related activity in these reserves during the nine months ended June 30, 2019. The severance and facility cost reserves were primarily recorded within accrued expenses and other liabilities in the Condensed Consolidated Balance Sheet as of June 30, 2019.
Plant restructuring During the nine months ended June 30, 2019, Specialty Ingredients committed to a cost reduction plan within an existing manufacturing facility. As a result, Ashland incurred restructuring charges of zero and $47 million for the three and nine months ended June 30, 2019, respectively. These charges were recorded primarily within the cost of sales caption of the Statements of Consolidated Comprehensive Income (Loss) consisting of $38 million of accelerated depreciation and amortization, $5 million of severance and $4 million of plant closure costs during the nine months ended June 30, 2019. As of June 30, 2019, there was a restructuring reserve of $1 million related to the $5 million of severance costs and $2 million related to the $4 million of plant closure costs. The restructuring plan is expected to be completed during fiscal 2019.

| Fair Value Measurements |
NOTE E – FAIR VALUE MEASUREMENTS As required by U.S. GAAP, Ashland uses applicable guidance for defining fair value, the initial recording and periodic remeasurement of certain assets and liabilities measured at fair value and related disclosures for instruments measured at fair value. Fair value accounting guidance establishes a fair value hierarchy, which prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). An instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the instrument’s fair value measurement. The three levels within the fair value hierarchy are described as follows. Level 1 – Observable inputs such as unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3 – Unobservable inputs for the asset or liability for which there is little, if any, market activity at the measurement date. Unobservable inputs reflect Ashland’s own assumptions about what market participants would use to price the asset or liability. The inputs are developed based on the best information available in the circumstances, which might include Ashland’s own financial data such as internally developed pricing models, discounted cash flow methodologies, as well as instruments for which the fair value determination requires significant management judgment. For assets that are measured using quoted prices in active markets (Level 1), the total fair value is the published market price per unit multiplied by the number of units held without consideration of transaction costs. Assets and liabilities that are measured using significant other observable inputs (Level 2) are primarily valued by reference to quoted prices of similar assets or liabilities in active markets, adjusted for any terms specific to that asset or liability. For all other assets and liabilities for which unobservable inputs are used (Level 3), fair value is derived using fair value models, such as a discounted cash flow model or other standard pricing models that Ashland deems reasonable. The following table summarizes financial instruments subject to recurring fair value measurements as of June 30, 2019.
(a) Included in restricted investments is $19 million classified in the other current assets caption on the Condensed Consolidated Balance Sheets.
The following table summarizes financial asset instruments subject to recurring fair value measurements as of September 30, 2018.
Restricted investments Investment income and realized gains and losses on these company-restricted investments are reported within the net interest and other financing expense caption on the Statements of Consolidated Comprehensive Income (Loss). In prior periods, the unrealized gains and losses on the equity securities were reported within the stockholders' equity section of the Condensed Consolidated Balance Sheets as a component of AOCI, net of the related deferred income taxes. Due to the accounting guidance adopted in the current year, as discussed in Note A, the unrealized gains and losses are now recognized in net income and are recorded within the net interest and other expense (income) caption in the Statements of Consolidated Comprehensive Income (Loss). The following table provides a summary of the activity within the investment portfolio as of June 30, 2019 and September 30, 2018:
The following table presents gross unrealized gains and losses for the restricted investment securities as of June 30, 2019 and September 30, 2018:
The unrealized gains and losses of $54 million, net of the related deferred income taxes of $20 million, as of September 30, 2018, were reclassified from AOCI to retained earnings within the Condensed Consolidated Balance Sheets due to the new accounting guidance adopted in the first quarter of fiscal year 2019. The following table presents the investment income, net unrealized gains and losses, realized gains and disbursements related to the investments within the portfolio for the three and nine months ended June 30, 2019 and 2018.
Deferred compensation investments Deferred compensation investments consist of Level 2 measurements within the fair value hierarchy which are comprised primarily of a guaranteed interest fund, a common stock index fund and an intermediate investment grade bond fund. Gains and losses related to deferred compensation investments are immediately recognized within the selling, general and administrative expense caption on the Statements of Consolidated Comprehensive Income (Loss). These investments generated gains of $2 million and $3 million during the three and nine months ended June 30, 2019, respectively, and $2 million and $6 million during the three and nine months ended June 30, 2018, respectively. Foreign currency derivatives Ashland conducts business in a variety of foreign currencies. Accordingly, Ashland regularly uses foreign currency derivative instruments to manage exposure on certain transactions denominated in foreign currencies to curtail potential earnings volatility effects on certain assets and liabilities, including short-term inter-company loans, denominated in currencies other than Ashland’s functional currency of an entity. These derivative contracts generally require exchange of one foreign currency for another at a fixed rate at a future date and generally have maturities of less than twelve months. All contracts are valued at fair value with net changes in fair value recorded within the selling, general and administrative expense caption. The impacts of these contracts were largely offset by gains and losses resulting from the impact of changes in exchange rates on transactions denominated in non-functional currencies. The following table summarizes the net gains and losses recognized during the three and nine months ended June 30, 2019 and 2018 within the Statements of Consolidated Comprehensive Income (Loss).
The following table summarizes the fair values of the outstanding foreign currency derivatives as of June 30, 2019 and September 30, 2018 included in accounts receivable and accrued expenses and other liabilities of the Condensed Consolidated Balance Sheets.
Other financial instruments At June 30, 2019 and September 30, 2018, Ashland's long-term debt (including the current portion and excluding debt issuance cost discounts) had a carrying value of $2,299 million and $2,307 million, respectively, compared to a fair value of $2,437 million and $2,372 million, respectively. The fair values of long-term debt are based on quoted market prices or, if market prices are not available, the present values of the underlying cash flows discounted at Ashland’s incremental borrowing rates, which are deemed to be Level 2 measurements within the fair value hierarchy.

| Goodwill and Other Intangibles |
NOTE G – GOODWILL AND OTHER INTANGIBLES Goodwill Ashland reviews goodwill and indefinite-lived intangible assets for impairment annually or when events and circumstances indicate an impairment may have occurred. This annual assessment is performed as of July 1 and consists of Ashland determining each reporting unit’s current fair value compared to its current carrying value. For its July 1, 2018 assessment, Ashland determined that its reporting units for the allocation of goodwill were its three reportable segments: Specialty Ingredients, Composites and Intermediates and Solvents. At that time, Ashland determined no additional impairment existed. Due to the expected divestiture of the Composites reporting unit, Ashland has two remaining reporting units as of June 30, 2019: Specialty Ingredients and Intermediates and Solvents. See Note B for more information on the expected divestiture. The following is a progression of goodwill by reportable segment for the nine months ended June 30, 2019.
Intangibles Intangible assets principally consist of trademarks and trade names, intellectual property and customer and supplier relationships. Intangible assets classified as finite are amortized on a straight-line basis over their estimated useful lives. The cost of trademarks and trade names is amortized principally over 3 to 25 years, intellectual property over 5 to 25 years, and customer and supplier relationships over 3 to 24 years. Ashland annually reviews indefinite-lived intangible assets for possible impairment or whenever events or changes in circumstances indicate that carrying amounts may not be recoverable. Intangible assets were comprised of the following as of June 30, 2019 and September 30, 2018.
Amortization expense recognized on intangible assets was $22 million and $23 million for the three months ended June 30, 2019 and 2018, respectively, and $65 million and $69 million for the nine months ended June 30, 2019 and 2018, respectively, and is included in the selling, general and administrative expense caption of the Statements of Consolidated Comprehensive Income (Loss). Estimated amortization expense for future periods is $86 million in 2019 (includes nine months actual and three months estimated), $86 million in 2020, $85 million in 2021, $85 million in 2022 and $85 million in 2023. The amortization expense for future periods is an estimate. Actual amounts may change from such estimated amounts due to fluctuations in foreign currency exchange rates, additional intangible asset acquisitions and divestitures, potential impairment, accelerated amortization, or other events. |

| Income Taxes |
NOTE I – INCOME TAXES Tax Law Changes The Tax Cuts and Jobs Act (Tax Act) was enacted on December 22, 2017. The Tax Act reduced the U.S. federal corporate tax rate from 35% to 21%, required companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and created new taxes on certain foreign sourced earnings. Through September 30, 2018 we recorded provisional amounts for certain enactment date effects of the Tax Act by applying the guidance in SAB 118 because we had not yet completed our enactment date accounting for these effects. During 2019, Ashland completed its internal accounting assessment for the tax effects of enactment of the Tax Act and recorded adjustments to provisional amounts previously recorded. Ashland’s final assessment resulted in net unfavorable tax adjustments of $24 million during the three months ended December 31, 2018 and an unfavorable $6 million during the three months ended June 30, 2019. These adjustments are primarily related to the one-time transition tax assessed on foreign cash and unremitted earnings. There could be additional guidance issued subsequent to December 31, 2018 that could impact our interpretation of the Tax Act and such changes could affect the amounts recorded. The impact, if any, of further transitional tax guidance that may be issued by the U.S. Treasury would be reflected in the Company’s provision for income tax in the period such guidance is effective. Deferred tax assets and liabilities Ashland remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is 21%. Ashland finalized its assessment of the provisional amount previously recorded for the remeasurement of the deferred tax balance which resulted in an unfavorable tax adjustment of $2 million during the three months ended December 31, 2018. Foreign tax effects The one-time transition tax is based on Ashland's total post-1986 earnings and profits of foreign subsidiaries that were previously deferred from U.S. income taxes. Ashland finalized its assessment of the provisional amount previously recorded for this one-time transition tax liability which resulted in an unfavorable tax adjustment of $22 million during the three months ended December 31, 2018 and a $6 million unfavorable tax adjustment during the three months ended June 30, 2019. After these final adjustments, the total obligation for the one-time transition tax was $57 million as of June 30, 2019. No additional income taxes have been provided for any remaining undistributed foreign earnings or any additional outside basis difference, as these amounts continue to be indefinitely reinvested in foreign operations. Ashland determined that the amount of unrecognized deferred tax liability related to any remaining undistributed foreign earnings calculations and additional outside basis difference is not practicable at this time. Global Intangible Low-Taxed Income Regarding new Global Intangible Low-Taxed Income (GILTI) tax rules, Ashland made an election to treat taxes due on future GILTI exclusions as a current period expense when incurred. Current fiscal year Ashland’s effective tax rate in any interim period is subject to adjustments related to discrete items and the mix of domestic and foreign operating results. The overall effective tax rate was a negative 5% for the three months ended June 30, 2019 and 114% for the nine months ended June 30, 2019. The current quarter tax rate was primarily impacted by income mix, as well as $2 million in net favorable tax discrete items including the favorable adjustment from the release of reserves related to unrecognized tax benefits and the unfavorable adjustment related to transaction tax and other items. The current nine month period was primarily impacted by the items referenced in the three-month period, as well as a net $17 million from unfavorable tax discrete items including the final assessment of the Tax Act and other items. Prior fiscal year The overall effective tax rate was not meaningful for the three months ended June 30, 2018 and a negative 17% for the nine months ended June 30, 2018. The quarter rate was primarily impacted by income mix and net favorable tax discrete adjustments of $5 million related to a state tax rate change and other items. The nine-month period was primarily impacted by the items referenced in the quarter, as well as a net $6 million from unfavorable tax discrete items including the assessment of the Tax Act, the tax rate change in a foreign country, and other items. Unrecognized tax benefits Changes in unrecognized tax benefits are summarized as follows for the nine months ended June 30, 2019.
From a combination of statute expirations and audit settlements in the next twelve months, Ashland expects a decrease in the amount accrued for uncertain tax positions of between $2 million and $4 million for continuing operations. It is reasonably possible that there could be other material changes to the amount of uncertain tax positions due to activities of the taxing authorities, settlement of audit issues or the reassessment of existing uncertain tax positions; however, Ashland is not able to estimate the impact of these items at this time.

NOTE J - EMPLOYEE BENEFIT PLANS Plan contributions For the nine months ended June 30, 2019, Ashland contributed $3 million to its non-U.S. pension plans and $1 million to its U.S. pension plans. Ashland expects to make additional contributions of approximately $2 million to its non-U.S. plans during the remainder of 2019. Plan remeasurement Ashland settled a non-U.S. pension plan during the first quarter of fiscal 2019, which required the plan to be remeasured. This remeasurement resulted in a curtailment gain of $18 million. Components of net periodic benefit costs (income) The following table details the components of pension and other postretirement benefit costs for continuing operations.
For segment reporting purposes, service cost is proportionately allocated to each segment, excluding the Unallocated and other segment, and is recorded within the selling, general and administrative expense and cost of sales captions on the Statements of Consolidated Comprehensive Loss (Income). All other components are recorded within the other net periodic benefit income caption on the Statements of Consolidated Comprehensive Loss (Income).

| Litigation, Claims and Contingencies |
NOTE K – LITIGATION, CLAIMS AND CONTINGENCIES Asbestos litigation Ashland and Hercules have liabilities from claims alleging personal injury caused by exposure to asbestos. To assist in developing and annually updating independent reserve estimates for future asbestos claims and related costs given various assumptions, Ashland retained Nathan Associates Inc. (Nathan). The methodology used by Nathan to project future asbestos costs is based largely on recent experience, including claim-filing and settlement rates, disease mix, enacted legislation, open claims and litigation defense. The claim experience of Ashland and Hercules are separately compared to the results of previously conducted third party epidemiological studies estimating the number of people likely to develop asbestos-related diseases. Those studies were undertaken in connection with national analyses of the population expected to have been exposed to asbestos. Using that information, Nathan estimates a range of the number of future claims that may be filed, as well as the related costs that may be incurred in resolving those claims. Changes in asbestos-related liabilities and receivables are recorded on an after-tax basis within the discontinued operations caption in the Statements of Consolidated Comprehensive Income (Loss). Ashland asbestos-related litigation The claims alleging personal injury caused by exposure to asbestos asserted against Ashland result primarily from indemnification obligations undertaken in 1990 in connection with the sale of Riley Stoker Corporation (Riley). The amount and timing of settlements and number of open claims can fluctuate from period to period. A summary of Ashland asbestos claims activity, excluding Hercules claims, follows.
Ashland asbestos-related liability From the range of estimates, Ashland records the amount it believes to be the best estimate of future payments for litigation defense and claim settlement costs, which generally approximates the mid-point of the estimated range of exposure from model results. Ashland reviews this estimate and related assumptions quarterly and annually updates the results of a non-inflated, non-discounted approximate 50-year model developed with the assistance of Nathan. During the most recent annual update of this estimate completed during the June 2019 quarter, it was determined that the liability for Ashland asbestos-related claims should be increased by $1 million. Total reserves for asbestos claims were $360 million at June 30, 2019 compared to $380 million at September 30, 2018. A progression of activity in the asbestos reserve is presented in the following table.
Ashland asbestos-related receivables Ashland has insurance coverage for certain litigation defense and claim settlement costs incurred in connection with its asbestos claims, and coverage-in-place agreements exist with the insurance companies that provide substantially all of the coverage that will be accessed. For the Ashland asbestos-related obligations, Ashland has estimated the value of probable insurance recoveries associated with its asbestos reserve based on management’s interpretations and estimates surrounding the available or applicable insurance coverage, including an assumption that all solvent insurance carriers remain solvent. A substantial portion of the estimated receivables from insurance companies are expected to be due from domestic insurers. At June 30, 2019, Ashland’s receivable for recoveries of litigation defense and claim settlement costs from insurers amounted to $130 million (excluding the Hercules receivable for asbestos claims) compared to $140 million at September 30, 2018. During the June 2019 quarter, the annual update of the model used for purposes of valuing the asbestos reserve and its impact on valuation of future recoveries from insurers was completed. This model update resulted in a $5 million decrease in the receivable for probable insurance recoveries. A progression of activity in the Ashland insurance receivable is presented in the following table.
Hercules asbestos-related litigation Hercules has liabilities from claims alleging personal injury caused by exposure to asbestos. Such claims typically arise from alleged exposure to asbestos fibers from resin encapsulated pipe and tank products which were sold by one of Hercules’ former subsidiaries to a limited industrial market. The amount and timing of settlements and number of open claims can fluctuate from period to period. A summary of Hercules’ asbestos claims activity follows.
Hercules asbestos-related liability From the range of estimates, Ashland records the amount it believes to be the best estimate of future payments for litigation defense and claim settlement costs, which generally approximates the mid-point of the estimated range of exposure from model results. Ashland reviews this estimate and related assumptions quarterly and annually updates the results of a non-inflated, non-discounted approximate 50-year model developed with the assistance of Nathan. As a result of the most recent annual update of this estimate, completed during the June 2019 quarter, it was determined that the liability for Hercules asbestos-related claims should be decreased by $10 million. Total reserves for asbestos claims were $257 million at June 30, 2019 compared to $282 million at September 30, 2018. A progression of activity in the asbestos reserve is presented in the following table.
Hercules asbestos-related receivables For the Hercules asbestos-related obligations, certain reimbursement obligations pursuant to coverage-in-place agreements with insurance carriers exist. As a result, any increases in the asbestos reserve have been partially offset by probable insurance recoveries. Ashland has estimated the value of probable insurance recoveries associated with its asbestos reserve based on management’s interpretations and estimates surrounding the available or applicable insurance coverage, including an assumption that all solvent insurance carriers remain solvent. The estimated receivable consists exclusively of solvent domestic insurers. As of June 30, 2019, Ashland’s receivable for recoveries of litigation defense and claims costs from insurers with respect to Hercules amounted to $49 million. During the June 2019 quarter, the annual update of the model used for purposes of valuing the asbestos reserve and its impact on valuation of future recoveries from insurers was completed. This model update resulted in a decrease of $5 million in the receivable for probable insurance recoveries. A progression of activity in the Hercules insurance receivable is presented in the following table.
Asbestos litigation cost projection Projecting future asbestos costs is subject to numerous variables that are extremely difficult to predict. In addition to the significant uncertainties surrounding the number of claims that might be received, other variables include the type and severity of the disease alleged by each claimant, the long latency period associated with asbestos exposure, mortality rates, dismissal rates, costs of medical treatment, the impact of bankruptcies of other companies that are co-defendants in claims, uncertainties surrounding the litigation process from jurisdiction to jurisdiction and from case to case, and the impact of potential changes in legislative or judicial standards. Furthermore, any predictions with respect to these variables are subject to even greater uncertainty as the projection period lengthens. Considering these inherent uncertainties, Ashland believes that the asbestos reserves for Ashland and Hercules represent the best estimate within a range of possible outcomes. As a part of the process to develop these estimates of future asbestos costs, a range of long-term cost models was developed. These models are based on national studies that predict the number of people likely to develop asbestos-related diseases and are heavily influenced by assumptions regarding long-term inflation rates for indemnity payments and legal defense costs, as well as other variables mentioned previously. Ashland has currently estimated in various models ranging from approximately 40 to 50 year periods that it is reasonably possible that total future litigation defense and claim settlement costs on an inflated and undiscounted basis could range as high as approximately $550 million for the Ashland asbestos-related litigation (current reserve of $360 million) and approximately $390 million for the Hercules asbestos-related litigation (current reserve of $257 million), depending on the combination of assumptions selected in the various models. If actual experience is worse than projected, relative to the number of claims filed, the severity of alleged disease associated with those claims or costs incurred to resolve those claims, or actuarial refinement or improvements to the assumptions used within these models are initiated, Ashland may need to further increase the estimates of the costs associated with asbestos claims and these increases could be material over time. Environmental remediation and asset retirement obligations Ashland is subject to various federal, state and local environmental laws and regulations that require environmental assessment or remediation efforts (collectively, environmental remediation) at multiple locations. At June 30, 2019, such locations included 80 waste treatment or disposal sites where Ashland has been identified as a potentially responsible party under Superfund or similar state laws, 113 current and former operating facilities and about 1,225 service station properties, of which 30 are being actively remediated. Ashland’s reserves for environmental remediation and related environmental litigation amounted to $192 million at June 30, 2019 compared to $187 million at September 30, 2018, of which $152 million at June 30, 2019 and $147 million at September 30, 2018 were classified in other noncurrent liabilities on the Condensed Consolidated Balance Sheets. The remaining reserves were classified in accrued expenses and other liabilities on the Condensed Consolidated Balance Sheets. The following table provides a reconciliation of the changes in the environmental remediation reserves during the nine months ended June 30, 2019 and 2018.
The total reserves for environmental remediation reflect Ashland’s estimates of the most likely costs that will be incurred over an extended period to remediate identified conditions for which the costs are reasonably estimable, without regard to any third-party recoveries. Engineering studies, probability techniques, historical experience and other factors are used to identify and evaluate remediation alternatives and their related costs in determining the estimated reserves for environmental remediation. Ashland continues to discount certain environmental sites and regularly adjusts its reserves as environmental remediation continues. Ashland has estimated the value of its probable insurance recoveries associated with its environmental reserve based on management’s interpretations and estimates surrounding the available or applicable insurance coverage. At June 30, 2019 and September 30, 2018, Ashland’s recorded receivable for these probable insurance recoveries was $13 million and $12 million, respectively, of which $12 million and $11 million, respectively, at June 30, 2019 and September 30, 2018 were classified in other noncurrent assets on the Condensed Consolidated Balance Sheets. Components of environmental remediation expense included within the selling, general and administrative expense caption of the Statements of Consolidated Comprehensive Income (Loss) are presented in the following table for the three and nine months ended June 30, 2019 and 2018.
Environmental remediation reserves are subject to numerous inherent uncertainties that affect Ashland’s ability to estimate its share of the costs. Such uncertainties involve the nature and extent of contamination at each site, the extent of required cleanup efforts under existing environmental regulations, widely varying costs of alternate cleanup methods, changes in environmental regulations, the potential effect of continuing improvements in remediation technology, and the number and financial strength of other potentially responsible parties at multiparty sites. Although it is not possible to predict with certainty the ultimate costs of environmental remediation, Ashland currently estimates that the upper end of the reasonably possible range of future costs for identified sites could be as high as approximately $450 million. The largest reserve for any site is 14% of the remediation reserve. Other legal proceedings and claims In addition to the matters described above, there are other various claims, lawsuits and administrative proceedings pending or threatened against Ashland and its current and former subsidiaries. Such actions are with respect to commercial matters, product liability, toxic tort liability, and other environmental matters, which seek remedies or damages, some of which are for substantial amounts. While Ashland cannot predict with certainty the outcome of such actions, it believes that adequate reserves have been recorded and losses already recognized with respect to such actions were immaterial as of June 30, 2019 and September 30, 2018. There is a reasonable possibility that a loss exceeding amounts already recognized may be incurred related to these actions; however, Ashland believes that such potential losses were immaterial as of June 30, 2019 and September 30, 2018. |

| Stock Incentive Plans |
NOTE N – STOCK INCENTIVE PLANS Ashland has stock incentive plans under which key employees or directors are granted stock appreciation rights (SARs), performance awards or nonvested stock awards. Each program is typically a long-term incentive plan designed to link employee compensation with increased shareholder value or reward superior performance and encourage continued employment with Ashland. Ashland recognizes compensation expense for the grant date fair value of stock-based awards over the applicable vesting period. The components of Ashland’s pre-tax stock-based compensation expense included in continuing operations are as follows:
SARs SARs are granted to employees or directors at a price equal to the fair market value of the stock on the date of grant and typically become exercisable over periods of one to three years. Unexercised SARs generally lapse ten years after the date of grant. SARs granted for nine months ended June 30, 2019 and 2018 were 300 thousand and 470 thousand, respectively. As of June 30, 2019, there was $8 million of total unrecognized compensation costs related to SARs. That cost is expected to be recognized over a weighted-average period of 1.8 years. Ashland estimates the fair value of SARs granted using the Black-Scholes option-pricing model. This model requires several assumptions which Ashland has developed and updates based on historical trends and current market observations. The accuracy of these assumptions is critical to the estimate of fair value for these equity instruments. Nonvested stock awards Nonvested stock awards are granted to employees or directors at a price equal to the fair market value of the stock on the date of grant and generally vest over a one-to-five-year period. However, such shares or units are subject to forfeiture upon termination of service before the vesting period ends. Only nonvested stock awards granted in the form of shares entitle employees or directors to vote the shares. Dividends on nonvested stock awards granted are in the form of additional units or shares of nonvested stock awards, which are subject to vesting and forfeiture provisions. Stock-settled nonvested stock awards Nonvested stock awards granted in the form of shares or units were 1 thousand and 2 thousand for the three months ended June 30, 2019 and 2018, respectively, and 95 thousand and 146 thousand for the nine months ended June 30, 2019 and 2018, respectively. As of June 30, 2019, there was $9 million of total unrecognized compensation costs related to these nonvested stock awards. That cost is expected to be recognized over a weighted-average period of 1.9 years. Cash-settled nonvested stock awards Certain nonvested stock awards are granted to employees and are settled in cash upon vesting. As of June 30, 2019, 113 thousand cash-settled nonvested stock awards were outstanding. The value of these cash-settled nonvested stock awards changes in connection with changes in the fair market value of the Ashland Common Stock. These awards generally vest over a period of three years. The expense recognized related to cash-settled nonvested stock awards was $2 million and $3 million during the three months ended June 30, 2019 and 2018, respectively, and $5 million and $7 million during the nine months ended June 30, 2019 and 2018, respectively. Executive performance incentive and retention program During 2016, certain executives were granted performance-based restricted shares of Ashland in order to provide an incentive to remain employed in the period after the full separation of Ashland and Valvoline. At June 30, 2019, there were 30 thousand shares outstanding in connection with these awards, which includes forfeitures and the cumulative value of forfeitable dividends. The expense recognition for these awards commenced upon completing the full separation of Valvoline which occurred on May 12, 2017 and resulted in $1 million and $2 million of expense for the three and nine months ended June 30, 2019, respectively, and $1 million and $4 million of expense for the three and nine months ended June 30, 2018, respectively. As of June 30, 2019, there was $1 million of total unrecognized compensation costs related to these awards. Performance awards Ashland sponsors a long-term incentive plan that awards performance shares/units to certain key employees that are primarily tied to Ashland’s overall financial performance relative to internal targets. Additionally, certain outstanding performance awards are tied to Ashland's overall financial performance relative to the financial performance of selected industry peer groups. Awards are granted annually, with each award covering a three-year vesting period. Awards settled in shares are recorded as a component of stockholders’ equity while awards settled in cash are recorded as a liability within the Condensed Consolidated Balance Sheets. The performance measure used to determine the actual number of performance shares/units issuable upon vesting is the financial performance of Ashland compared to award targets. The financial performance award metric is considered a performance condition under applicable U.S. GAAP. Additionally, the actual number of performance shares/units issuable upon vesting can be potentially increased or decreased based on a total shareholder return (TSR) performance modifier relative to peers of Ashland. For awards granted in fiscal 2017, each performance unit will be settled in cash based on the fair value of Ashland common stock. For awards granted in fiscal 2018 and 2019, each performance share/unit is convertible to one share of Ashland Common Stock. Nonvested performance shares/units do not entitle employees to vote the shares or to receive any dividends thereon. No performance shares/units were granted for the three months ended June 30, 2019 and 2018. Performance shares/units granted for the nine months ended June 30, 2019 and 2018 were 78 thousand and 101 thousand, respectively. As of June 30, 2019, there was $5 million of total unrecognized compensation costs related to performance shares/units. That cost is expected to be recognized over a weighted-average period of 1.6 years. |

| Revenue |
NOTE O – REVENUE Effective October 1, 2018, Ashland adopted accounting guidance outlining a single comprehensive five step model for entities to use in accounting for revenue arising from contracts with customers (ASC 606 Revenue from Contracts with Customers). As a result of the adoption, there was no material impact to Ashland’s Condensed Consolidated Financial Statements. The additional disclosures that Ashland is required to disclose on an interim and annual basis are contained within this Note O. Revenue recognition Ashland’s revenue is measured as the amount of consideration it expects to receive in exchange for transferring goods or providing services and is recognized when performance obligations are satisfied under the terms of contracts with customers. Ashland generally utilizes standardized language for the terms of contracts within each purchase order, unless a separate agreement has been entered into with a customer that supersedes the standard language within the purchase order. A performance obligation is deemed to be satisfied by Ashland when control of the product or service is transferred to the customer. The transaction price of a contract, or the amount Ashland expects to receive upon satisfaction of all performance obligations, is determined by reference to the contract’s terms and includes adjustments, if applicable, for any variable consideration, such as volume discounts, rebates, refunds and rights to return. Where a contract contains more than one distinct performance obligation, the transaction price is allocated to each performance obligation based on the standalone selling price of each performance obligation, although these situations do not occur frequently and are generally not included within Ashland’s contracts. Any unsatisfied performance obligations were not material. Standalone selling prices are based on prices Ashland charges to customers, which in some cases are based on established market prices. Ashland generally collects the cash from its customers within 60 days of the product delivery date. Sales and other similar taxes collected from customers on behalf of third parties are excluded from the contract price. All of Ashland’s revenue is derived from contracts with customers, and nearly all contracts with customers contain one performance obligation for the transfer of goods where such performance obligation is satisfied at a point in time. Control of a product is deemed to be transferred to the customer generally upon shipment or delivery. Costs for shipping and handling activities, whether performed before or after the customer obtains control of the goods, are accounted for as fulfillment costs when not reimbursed. Costs incurred to obtain contracts with customers have historically not been significant and are expensed immediately as the period of performance is generally one year or less. Ashland records bad debt expense in specific situations when it is determined that the customer is unable to meet its financial obligation. Practical expedients Upon adoption, Ashland utilized the following applicable practical expedients, as permitted by ASC 606, Revenue from Contracts with Customers:
Trade receivables Trade receivables are defined as receivables arising from contracts with customers and are recorded within the accounts receivable caption within the Condensed Consolidated Balance Sheets. Ashland’s trade receivables were $472 million and $482 million as of June 30, 2019 and September 30, 2018, respectively. Disaggregation of revenue Ashland disaggregates its revenue from contracts with customers by segment, geographical region and product category, as Ashland believes these categories best depict how management reviews the financial performance of its operations for the three and nine months ended June 30, 2018 and 2019. See the following tables for details:

| Segment Reporting [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Reportable Segment Information |
NOTE P – REPORTABLE SEGMENT INFORMATION Ashland determines its reportable segments based on how operations are managed internally for the products and services sold to customers, including how the results are reviewed by the chief operating decision maker, which includes determining resource allocation methodologies used for reportable segments. Operating income is the primary measure on the Statements of Consolidated Comprehensive Income (Loss) that is reviewed by the chief operating decision maker in assessing each reportable segment's financial performance. Ashland does not aggregate operating segments to arrive at these reportable segments. Change in Reportable Segments Ashland’s reportable segments were impacted in the current year due to the expected divestiture of the Composites reportable segment and Intermediates and Solvents Marl facility and reclassification to discontinued operations. As a result, Ashland's operations are managed by the chief operating decision maker within the following two reportable segments: Specialty Ingredients and Intermediates and Solvents. The financial information for Intermediates and Solvents excludes the activity from the Marl facility due to the expected divestiture and has therefore been restated in prior periods. Reportable segment business descriptions Specialty Ingredients offers industry-leading products, technologies and resources for solving formulation and product-performance challenges. Using natural, synthetic and semisynthetic polymers derived from cellulose ethers, vinyl pyrrolidones, acrylic polymers, polyester and polyurethane-based adhesives, and plant and seed extract, Specialty Ingredients offers comprehensive and innovative solutions for consumer and industrial applications. Key customers include pharmaceutical companies; makers of personal care products, food and beverages; makers of nutraceuticals and supplements; manufacturers of paint, coatings and construction materials; packaging and converting; and oilfield service companies. Intermediates and Solvents is a leading producer of 1,4 butanediol and related derivatives, including tetrahydrofuran and n-methylpyrrolidone. These products are used as chemical intermediates in the production of engineering polymers and polyurethanes, and as specialty process solvents in a wide array of applications including electronics, pharmaceuticals, water filtration membranes and more. Butanediol is also supplied to Ashland’s Specialty Ingredients business for use as a raw material. On November 15, 2018, Ashland announced that it had signed a definitive agreement to sell its Composites segment and Intermediates and Solvents Marl facility. As a result, the financial information for Intermediates and Solvents excludes the activity from the Marl facility due to the expected divestiture and has been restated in prior periods. Unallocated and Other generally includes items such as certain significant company-wide restructuring activities, including internal separation costs, and legacy costs or adjustments that relate to divested businesses that are no longer operated by Ashland. Reportable segment results Results of Ashland’s reportable segments are presented based on its management and internal accounting structure. The structure is specific to Ashland; therefore, the financial results of Ashland’s reportable segments are not necessarily comparable with similar information for other comparable companies. Ashland allocates all significant costs to its reportable segments except for certain significant company-wide restructuring activities, including stranded costs, and other costs or adjustments that relate to former businesses that Ashland no longer operates. The service cost component of pension and other postretirement benefits costs is allocated to each reportable segment on a ratable basis; while the remaining components of pension and other postretirement benefits costs are recorded within the other net periodic benefit income caption on the Statements of Consolidated Comprehensive Income (Loss). Ashland refines its expense allocation methodologies to the reportable segments from time to time as internal accounting practices are improved, more refined information becomes available and the industry or market changes. Significant revisions to Ashland’s methodologies are adjusted for all segments on a retrospective basis. The following table presents various financial information for each reportable segment for the three and nine months ended June 30, 2019 and 2018.

Significant Accounting Policies (Policies) |
9 Months Ended |
|---|---|
Jun. 30, 2019 | |
| Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
| Basis of Presentation |
Basis of presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial reporting and Securities and Exchange Commission (SEC) regulations. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. Additionally, certain prior period data, primarily related to discontinued operations, have been reclassified in the Consolidated Financial Statements and accompanying notes to conform to the current period presentation, as further described in this section. These statements omit certain information and footnote disclosures required for complete annual financial statements and, therefore, should be read in conjunction with Ashland Global Holdings Inc.’s (Ashland or the Company) Annual Report on Form 10-K for the fiscal year ended September 30, 2018. Results of operations for the period ended June 30, 2019 are not necessarily indicative of the expected results for the remaining quarters in the fiscal year. On November 15, 2018, Ashland announced that it had signed a definitive agreement to sell substantially all of the assets and liabilities of its Composites segment and Intermediates and Solvents facility in Marl, Germany (Marl facility). This expected divestiture represents a strategic shift in Ashland's business and, in accordance with U.S. GAAP, qualified as a discontinued operation. As a result, the operating results and cash flows related to Composites and the Marl facility have been reflected as discontinued operations in the Statements of Consolidated Comprehensive Income (Loss) and Statements of Condensed Consolidated Cash Flows. The assets and liabilities that are to be sold have met the requirements to be classified within the Condensed Consolidated Balance Sheets under a held for sale designation. See Notes B and C for additional information on this expected divestiture. As a result of classifying the Composites reporting segment as a discontinued operation, Ashland is now comprised of two reportable segments: Specialty Ingredients and Intermediates and Solvents. The financial information reported for Intermediates and Solvents excludes the activity from the Marl facility due to the expected divestiture. |
| Use of Estimates, Risk and Uncertainties |
Use of estimates, risks and uncertainties The preparation of Ashland’s Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosures of contingent assets and liabilities. Significant items that are subject to such estimates and assumptions include, but are not limited to, long-lived assets (including goodwill and other intangible assets), income taxes and liabilities and receivables associated with asbestos litigation and environmental remediation. Although management bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, actual results could differ significantly from the estimates under different assumptions or conditions. Ashland’s results are affected by domestic and international economic, political, legislative, regulatory and legal actions. Economic conditions, such as recessionary trends, inflation, interest and monetary exchange rates, government fiscal policies and changes in the prices of certain key raw materials, can have a significant effect on operations. While Ashland maintains reserves for anticipated liabilities and carries various levels of insurance, Ashland could be affected by civil, criminal, regulatory or administrative actions, claims or proceedings relating to asbestos, environmental remediation or other matters. |
| New Accounting Pronouncements |
New accounting pronouncements A description of new U.S. GAAP accounting standards issued or adopted during the current year is required in interim financial reporting. A detailed listing of new accounting standards relevant to Ashland is included in the Annual Report on Form 10-K for the fiscal year ended September 30, 2018. The following standards relevant to Ashland were either issued or adopted in the current period or will become effective in a subsequent period. Revenue recognition In May 2014, the FASB issued accounting guidance outlining a single comprehensive five step model for entities to use in accounting for revenue arising from contracts with customers (ASC 606 Revenue from Contracts with Customers). The new guidance and subsequent amendments to it superseded most current revenue recognition guidance, in an effort to converge the revenue recognition principles within U.S. GAAP. This new guidance required entities to disclose certain quantitative and qualitative information regarding the nature, amount, timing and uncertainty of qualifying revenue and cash flows arising from contracts with customers. Entities had the option of using a full retrospective or a modified retrospective approach to adopt the new guidance. This guidance became effective for Ashland on October 1, 2018. Ashland formed an implementation team that evaluated the impact of the new standard on the Condensed Consolidated Financial Statements and the adoption method options available as well as the overall impact the new guidance would have on the organization. The assessment process consisted of categorizing Ashland’s revenue streams and reviewing the current internal accounting policies and practices to determine potential differences that could result from applying the requirements of the new standard to revenue contracts. Additional discussions and meetings with each revenue stream team occurred to solicit input, identify potential impacts and appropriate changes to Ashland’s business processes, systems and controls to support the revenue recognition and disclosure requirements under the new standard. Ashland elected to adopt this standard using the modified retrospective approach and determined that the overall impact was not material to the Condensed Consolidated Financial Statements. As a result, no cumulative-effect adjustment was made to retained earnings in the Condensed Consolidated Balance Sheets. Further, there has been no significant change to the manner and timing of recognizing revenue. However, there are significant additional disclosures within the Notes to Condensed Consolidated Financial Statements. ASC 606 requires disclosure of disaggregated revenue into categories that depict the nature of how Ashland's revenue and cash flows are affected by economic factors. Additionally, Ashland is required to disclose additional information related to its revenue recognition policy. See Note O for these additional disclosures. Leases In February 2016, the FASB issued new accounting guidance related to lease transactions. The main objective of this guidance is to increase transparency and comparability among organizations by requiring lessees to recognize assets and liabilities on the balance sheet for the right to use assets and obligations created by leases and to disclose key information about leasing arrangements. The presentation of the Statements of Consolidated Comprehensive Income (Loss) and the Statements of Condensed Consolidated Cash Flows is largely unchanged under this guidance. This guidance retains a distinction between finance leases and operating leases, and the classification criteria for distinguishing between finance leases and operating leases are substantially similar to the classification criteria for distinguishing between capital leases and operating leases in the current accounting literature. The guidance will become effective for Ashland on October 1, 2019 and it will have a significant effect on Ashland’s Condensed Consolidated Balance Sheet and disclosures. In July 2018, the FASB amended this guidance to give entities the option to apply the standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Ashland will utilize this transition method upon adopting the guidance. Ashland will also elect the practical expedient package related to the identification, classification and accounting for initial direct costs whereby prior conclusions do not have to be reassessed for leases that commenced before the effective date. As Ashland will not reassess such conclusions, Ashland does not plan to adopt the practical expedient to use hindsight to determine the likelihood of whether a lease will be extended, terminated or whether a purchase option will be exercised. Ashland’s implementation team is continuing to identify leases, determine policy elections, gather data, implement changes to business processes and controls, and quantifying the impact that this guidance will have within its Condensed Consolidated Financial Statements. Other accounting pronouncements In January 2016, the FASB issued accounting guidance related to the recognition and measurement as well as the presentation and disclosures for certain financial instruments. Most notably, the guidance requires entities to measure equity investments at fair value and to recognize any changes in fair value in net income rather than accumulated other comprehensive income (AOCI). The guidance became effective for Ashland on October 1, 2018 and resulted in Ashland recording a cumulative-effect adjustment to reclassify net after-tax unrealized gains of $34 million on its equity securities from AOCI to retained earnings. In the current period, the adoption of this guidance resulted in a significant impact to net income as Ashland recognized investment gains of $6 million and $3 million for the three and nine months ended June 30, 2019, respectively, within the net interest and other expense caption on the Statement of Consolidated Comprehensive Income (Loss). The impact of this new guidance could continue to have a material impact on Ashland’s Statements of Consolidated Comprehensive Income (Loss) in prospective periods depending on the fluctuations of unrealized gains and losses within the investment securities portfolio. For current and future periods, the changes in fair value of the equity securities will no longer be classified within other comprehensive income under the new guidance. For further information on Ashland’s equity securities, see Note E. In October 2016, the FASB issued new accounting guidance which requires entities to recognize the income tax effects of intercompany transfers of assets other than inventory when the transfer occurs. This guidance eliminates the exception under previous U.S. GAAP that the income tax effects of all intercompany transfers of assets other than inventory be deferred until the assets are sold to a third party or otherwise recovered through use. This guidance became effective for Ashland on October 1, 2018 and was applied using a modified retrospective approach. Consequently, Ashland recorded a cumulative-effect adjustment to reclassify less than $1 million from other current assets and deferred taxes to retained earnings. |
| Fair Value of Financial Instruments Policy |
As required by U.S. GAAP, Ashland uses applicable guidance for defining fair value, the initial recording and periodic remeasurement of certain assets and liabilities measured at fair value and related disclosures for instruments measured at fair value. Fair value accounting guidance establishes a fair value hierarchy, which prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). An instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the instrument’s fair value measurement. The three levels within the fair value hierarchy are described as follows. Level 1 – Observable inputs such as unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3 – Unobservable inputs for the asset or liability for which there is little, if any, market activity at the measurement date. Unobservable inputs reflect Ashland’s own assumptions about what market participants would use to price the asset or liability. The inputs are developed based on the best information available in the circumstances, which might include Ashland’s own financial data such as internally developed pricing models, discounted cash flow methodologies, as well as instruments for which the fair value determination requires significant management judgment. For assets that are measured using quoted prices in active markets (Level 1), the total fair value is the published market price per unit multiplied by the number of units held without consideration of transaction costs. Assets and liabilities that are measured using significant other observable inputs (Level 2) are primarily valued by reference to quoted prices of similar assets or liabilities in active markets, adjusted for any terms specific to that asset or liability. For all other assets and liabilities for which unobservable inputs are used (Level 3), fair value is derived using fair value models, such as a discounted cash flow model or other standard pricing models that Ashland deems reasonable. |
| Inventories |
Inventories are carried at the lower of cost or net realizable value. Inventories are primarily stated at cost using the weighted-average cost method. In addition, certain inventories are valued at cost using the last-in, first-out (LIFO) method. |
| Goodwill and Intangible Assets, Goodwill |
Ashland reviews goodwill and indefinite-lived intangible assets for impairment annually or when events and circumstances indicate an impairment may have occurred. This annual assessment is performed as of July 1 and consists of Ashland determining each reporting unit’s current fair value compared to its current carrying value. For its July 1, 2018 assessment, Ashland determined that its reporting units for the allocation of goodwill were its three reportable segments: Specialty Ingredients, Composites and Intermediates and Solvents. At that time, Ashland determined no additional impairment existed. Due to the expected divestiture of the Composites reporting unit, Ashland has two remaining reporting units as of June 30, 2019: Specialty Ingredients and Intermediates and Solvents. See Note B for more information on the expected divestiture. |
| Finite-Lived Intangible Asset |
Intangible assets principally consist of trademarks and trade names, intellectual property and customer and supplier relationships. Intangible assets classified as finite are amortized on a straight-line basis over their estimated useful lives. The cost of trademarks and trade names is amortized principally over 3 to 25 years, intellectual property over 5 to 25 years, and customer and supplier relationships over 3 to 24 years. |
| Goodwill and Intangible Assets, Intangible Assets, Indefinite-Lived |
Ashland annually reviews indefinite-lived intangible assets for possible impairment or whenever events or changes in circumstances indicate that carrying amounts may not be recoverable. |
| Commitments and Contingencies Policy |
Ashland and Hercules have liabilities from claims alleging personal injury caused by exposure to asbestos. To assist in developing and annually updating independent reserve estimates for future asbestos claims and related costs given various assumptions, Ashland retained Nathan Associates Inc. (Nathan). The methodology used by Nathan to project future asbestos costs is based largely on recent experience, including claim-filing and settlement rates, disease mix, enacted legislation, open claims and litigation defense. The claim experience of Ashland and Hercules are separately compared to the results of previously conducted third party epidemiological studies estimating the number of people likely to develop asbestos-related diseases. Those studies were undertaken in connection with national analyses of the population expected to have been exposed to asbestos. Using that information, Nathan estimates a range of the number of future claims that may be filed, as well as the related costs that may be incurred in resolving those claims. Changes in asbestos-related liabilities and receivables are recorded on an after-tax basis within the discontinued operations caption in the Statements of Consolidated Comprehensive Income (Loss). |
| Environmental Cost Policy | The total reserves for environmental remediation reflect Ashland’s estimates of the most likely costs that will be incurred over an extended period to remediate identified conditions for which the costs are reasonably estimable, without regard to any third-party recoveries. Engineering studies, probability techniques, historical experience and other factors are used to identify and evaluate remediation alternatives and their related costs in determining the estimated reserves for environmental remediation. Ashland continues to discount certain environmental sites and regularly adjusts its reserves as environmental remediation continues. Ashland has estimated the value of its probable insurance recoveries associated with its environmental reserve based on management’s interpretations and estimates surrounding the available or applicable insurance coverage. |
| Earnings Per Share |
The following is the computation of basic and diluted earnings per share (EPS) from continuing operations attributable to Ashland. Stock appreciation rights (SARs), stock options and warrants available to purchase shares outstanding for each reporting period whose grant price was greater than the average market price of Ashland Common Stock for each applicable period were not included in the computation of income from continuing operations per diluted share because the effect of these instruments would be antidilutive. The total number of these shares outstanding was approximately 1 million and 0.7 million at June 30, 2019 and 2018, respectively. Earnings per share is reported under the treasury stock method. |
| Stock Incentive Plan Policy |
Ashland has stock incentive plans under which key employees or directors are granted stock appreciation rights (SARs), performance awards or nonvested stock awards. Each program is typically a long-term incentive plan designed to link employee compensation with increased shareholder value or reward superior performance and encourage continued employment with Ashland. Ashland recognizes compensation expense for the grant date fair value of stock-based awards over the applicable vesting period. |
| Segment Reporting |
Ashland determines its reportable segments based on how operations are managed internally for the products and services sold to customers, including how the results are reviewed by the chief operating decision maker, which includes determining resource allocation methodologies used for reportable segments. Operating income is the primary measure on the Statements of Consolidated Comprehensive Income (Loss) that is reviewed by the chief operating decision maker in assessing each reportable segment's financial performance. Ashland does not aggregate operating segments to arrive at these reportable segments. |
