| SIGNIFICANT ACCOUNTING POLICIES | Principles of consolidation and basis of presentation On September 20, 2016, Ashland was reincorporated under the laws of the State of Delaware through a tax-free reorganization under a new holding company structure (the Reorganization). As a result of the Reorganization, Ashland Global Holdings Inc. replaced Ashland Inc. as the publicly held corporation and, through its subsidiaries, now conducts all of the operations that historically were conducted by Ashland Inc. Pursuant to the terms of the Reorganization, each outstanding share of Ashland common stock was automatically converted into one share of Ashland Global Holdings Inc. common stock. Following consummation of the Reorganization, (i) Ashland Inc. was converted into Ashland LLC, an indirect, wholly owned subsidiary of Ashland Global Holdings Inc., and (ii) Ashland Global Holdings Inc., as the new holding company, will, through its subsidiaries, conduct all of the operations conducted by Ashland Inc. immediately prior to the Reorganization. The Consolidated Financial Statements include the accounts of Ashland Global Holdings Inc. and its majority owned subsidiaries and, when applicable, entities for which Ashland has a controlling financial interest or is the primary beneficiary (Ashland). For entities for which Ashland has a controlling financial interest but owns less than 100%, the outside stockholders’ interests are shown as noncontrolling interests. Investments in joint ventures and 20% to 50% owned affiliates where Ashland has the ability to exert significant influence are accounted for under the equity method. The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and U.S. Securities and Exchange Commission regulations. All material intercompany transactions and balances have been eliminated. Additionally, certain prior period data has been reclassified in the Consolidated Financial Statements and accompanying notes to conform to the current period presentation, which includes the adoption of of new accounting guidance during the current year related to the classification as noncurrent of all deferred tax assets and liabilities in the Consolidated Balance Sheet. Ashland is composed of three reportable segments: Ashland Specialty Ingredients (Specialty Ingredients), Ashland Performance Materials (Performance Materials) and Valvoline. As of September 30, 2016, Ashland maintains an approximately 83% controlling interest in Valvoline Inc., which holds the Valvoline reportable segment. See Note B for additional information. The term Valvoline as used herein, depending on context, refers to either Valvoline Inc. or Valvoline as a reportable segment of Ashland. On July 31, 2014, Ashland completed the sale of the assets and liabilities of Ashland Water Technologies (Water Technologies). As a result of the sale, all prior period operating results and cash flows related to Water Technologies have been reflected as discontinued operations in the Statements of Consolidated Comprehensive Income and Statements of Consolidated Cash Flows. During 2015, Ashland sold certain assets in its portfolio of businesses which were not reflected as discontinued operations. See Notes C and R for additional information on these activities as well as Ashland’s current reportable segment results. Use of estimates, risks and uncertainties The preparation of Ashland’s 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), employee benefit obligations, 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. Cash and cash equivalents Cash and cash equivalents include cash on hand and highly liquid investments maturing within three months after purchase. Allowance for doubtful accounts Ashland records an allowance for doubtful accounts as a best estimate of the amount of probable credit losses for accounts receivable. Each month, Ashland reviews this allowance and considers factors such as customer credit, past transaction history with the customer and changes in customer payment terms when determining whether the collection of a receivable is reasonably assured. Past due balances over 90 days and over a specified amount are reviewed individually for collectibility. The allowance for doubtful accounts is adjusted when it becomes probable a receivable will not be recovered. A progression of activity in the allowance for doubtful accounts is presented in the following table.
Inventories Inventories are carried at the lower of cost or market. Inventories are primarily stated at cost using the weighted-average cost method. In addition, certain chemicals and lubricants with a replacement cost of $162 million at September 30, 2016 and $170 million at September 30, 2015 are valued at cost using the last-in, first-out (LIFO) method. The following summarizes Ashland’s inventories as of the Consolidated Balance Sheet dates.
A progression of activity in the inventory reserves, which reduce the amounts of finished products and raw materials, supplies and work in process reported, is presented in the following table.
Property, plant and equipment The cost of property, plant and equipment is depreciated by the straight-line method over the estimated useful lives of the assets. Buildings are depreciated principally over 25 to 35 years and machinery and equipment principally over 2 to 25 years. Such costs are periodically reviewed for recoverability when impairment indicators are present. Such indicators include, among other factors, operating losses, unused capacity, market value declines and technological obsolescence. Recorded values of asset groups of property, plant and equipment that are not expected to be recovered through undiscounted future net cash flows are written down to current fair value, which generally is determined from estimated discounted future net cash flows (assets held for use) or net realizable value (assets held for sale). Goodwill and other intangibles Ashland tests goodwill and other indefinite-lived intangible assets for impairment annually as of July 1 and when events and circumstances indicate an impairment may have occurred. Ashland reviews goodwill for impairment based on its identified reporting units, which are defined as operating segments or groupings of businesses one level below the operating segment level. Ashland tests goodwill for impairment by comparing the carrying value to the estimated fair value of its reporting units, determined using a combination of discounted cash flow models and valuations based on earnings multiples for guideline public companies in each reporting unit’s industry peer group, when externally quoted market prices are not readily available. If this comparison indicates that a reporting unit’s estimated fair value is less than its carrying value, a second step is required. If applicable, the second step requires the fair value of the reporting unit to be allocated to the estimated fair value of the reporting unit’s net assets, with any fair value in excess of amounts allocated to such net assets representing the implied fair value of goodwill for that reporting unit. The implied goodwill balance is compared to the actual carrying value of goodwill for the reporting unit to determine the goodwill impairment amount. Ashland tests its indefinite-lived intangible assets, principally trademarks and trade names, using a “relief-from-royalty” valuation method compared to the carrying value. Significant assumptions inherent in the valuation methodologies for goodwill and other intangibles are employed and include, but are not limited to, such estimates as future projected business results, growth rates, the weighted-average cost of capital for a market participant, and royalty and discount rates. If the carrying value of an individual indefinite-lived intangible asset exceeds its fair value, such individual indefinite-lived intangible asset is written down by an amount equal to such excess. Finite-lived intangible assets principally consist of certain trademarks and trade names, intellectual property, and customer lists. These intangible assets 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 20 years and customer relationships over 3 to 24 years. Ashland reviews finite-lived intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Ashland monitors these changes and events on at least a quarterly basis. For further information on goodwill and other intangible assets, see Note I. Derivative instruments Ashland regularly uses derivative instruments to manage its exposure to fluctuations in foreign currencies and certain commodities. All derivative instruments are recognized as either assets or liabilities on the balance sheet and are measured at fair value. Changes in the fair value of all derivatives are recognized immediately in income unless the derivative qualifies as a hedge of future cash flows or a hedge of a net investment in a foreign operation. Gains and losses related to a hedge are either recognized in income immediately to offset the gain or loss on the hedged item, or deferred and recorded in the stockholders’ equity section of the Consolidated Balance Sheets as a component of accumulated other comprehensive income and subsequently recognized in the Statements of Consolidated Comprehensive Income when the hedged item affects net income. The ineffective portion of the change in fair value of a hedge is recognized in income immediately. For additional information on derivative instruments, see Note G. Restricted investments On January 13, 2015, Ashland and Hercules LLC (formerly Hercules Incorporated), an indirect wholly-owned subsidiary of Ashland that was acquired in 2009, entered into a comprehensive settlement agreement related to certain insurance coverage for asbestos bodily injury claims with Underwriters at Lloyd’s, certain London companies and Chartis (AIG) member companies, along with National Indemnity Company and Resolute Management, Inc., under which Ashland and Hercules received a total of $398 million (the January 2015 asbestos insurance settlement). During 2015, Ashland placed $335 million of the settlement funds into a renewable annual trust restricted for the purpose of paying ongoing and future litigation defense and claim settlement costs incurred in conjunction with asbestos claims. These funds are presented primarily as noncurrent assets, with $30 million classified within other current assets in the Consolidated Balance Sheets as of September 30, 2016 and 2015. As of September 30, 2016, the funds within the trust were primarily invested in equity and corporate bond investments with a portion maintained in demand deposits. The funds within the trust are classified as available-for-sale securities. Available-for-sale securities are reported at fair value with unrealized gains and losses, net of related deferred income taxes, included in the stockholders’ equity section of the Consolidated Balance Sheets as a component of accumulated other comprehensive income. Interest income and realized gains and losses on the available-for-sale securities are reported in the net interest and other financing expense caption in the Statements of Consolidated Comprehensive Income. See Notes G and O for additional information regarding fair value of these investments within the trust and the January 2015 asbestos insurance settlement. Revenue recognition Sales generally are recognized when persuasive evidence of an arrangement exists, products are received or services are provided to customers, the sales price is fixed or determinable and collectibility is reasonably assured. Certain shipping and handling costs paid by the customer are recorded in sales, while those costs paid by Ashland are recorded in cost of sales. Expense recognition Cost of sales include material and production costs, as well as the costs of inbound and outbound freight, purchasing and receiving, inspection, warehousing, internal transfers and all other distribution network costs. Selling, general and administrative expense includes sales and marketing costs, advertising, customer support, environmental remediation, corporate and divisional administrative and other costs. Advertising costs ($64 million in 2016, $62 million in 2015 and $63 million in 2014) and research and development costs ($100 million in 2016, $110 million in 2015 and $114 million in 2014) are expensed as incurred. Income taxes Ashland is subject to income taxes in the United States and numerous foreign jurisdictions. Significant judgment in the forecasting of taxable income using historical and projected future operating results is required in determining Ashland’s provision for income taxes and the related assets and liabilities. The provision for income taxes includes income taxes paid, currently payable or receivable, and deferred taxes. Deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities, and are measured using enacted tax rates and laws that are expected to be in effect when the differences reverse. Deferred tax assets are also recognized for the estimated future effects of tax loss carryforwards. The effect on deferred taxes of changes in tax rates is recognized in the period in which the enactment date occurs. Valuation allowances are established when necessary on a jurisdictional basis to reduce deferred tax assets to the amounts expected to be realized. In the event that the actual outcome of future tax consequences differs from Ashland’s estimates and assumptions due to changes or future events such as tax legislation, geographic mix of earnings, completion of tax audits or earnings repatriation plans, the resulting change to the provision for income taxes could have a material effect on the Statements of Consolidated Comprehensive Income and Consolidated Balance Sheets. For additional information on income taxes, see Note M. A progression of activity in the tax valuation allowances for both continuing and discontinued operations is presented in the following table.
Asbestos-related litigation Ashland is subject to liabilities from claims alleging personal injury caused by exposure to asbestos. Such claims result from indemnification obligations undertaken in 1990 in connection with the sale of Riley Stoker Corporation (Riley) and the acquisition of Hercules Incorporated (Hercules) in November 2008. Although Riley, a former subsidiary, was neither a producer nor a manufacturer of asbestos, its industrial boilers contained some asbestos-containing components provided by other companies. Hercules, an indirect wholly-owned subsidiary of Ashland, 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 sold by one of Hercules’ former subsidiaries to a limited industrial market. Ashland retained Hamilton, Rabinovitz & Associates, Inc. (HR&A) to assist in developing and annually updating independent reserve estimates for future asbestos claims and related costs given various assumptions. The methodology used by HR&A to project future asbestos costs is based largely on Ashland’s recent experience, including claim-filing and settlement rates, disease mix, enacted legislation, open claims, and litigation defense. Ashland’s claim experience is compared to the results of previously conducted 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, HR&A 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. 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. For additional information on asbestos-related litigation, see Note O. Environmental remediation Accruals for environmental remediation are recognized when it is probable a liability has been incurred and the amount of that liability can be reasonably estimated. Such costs are charged to expense if they relate to the remediation of conditions caused by past operations or are not expected to mitigate or prevent contamination from future operations. Liabilities are recorded at estimated cost values based on experience, assessments and current technology, without regard to any third-party recoveries and are regularly adjusted as environmental assessments and remediation efforts continue. For additional information on environmental remediation, see Note O. Pension and other postretirement benefits The funded status of Ashland’s pension and other postretirement benefit plans is recognized in the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the benefit obligation at September 30, the measurement date. For defined benefit pension plans, the benefit obligation is the projected benefit obligation (PBO) and for the other postretirement benefit plans, the benefit obligation is the accumulated postretirement benefit obligation (APBO). The PBO represents the actuarial present value of benefits expected to be paid upon retirement based on estimated future compensation levels. The APBO represents the actuarial present value of postretirement benefits attributed to employee services already rendered. The measurement of the benefit obligation is based on Ashland’s estimates and actuarial valuations. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age and years of service, as well as certain key assumptions that require significant judgment, including, but not limited to, estimates of discount rates, expected return on plan assets, rate of compensation increases, interest rates and mortality rates. The fair value of plan assets represents the current market value of assets held by an irrevocable trust fund for the sole benefit of participants. For additional information regarding plan assumptions and the current financial position of the pension and other postretirement plans, see Note N. Ashland recognizes the change in the fair value of plan assets and net actuarial gains and losses annually in the fourth quarter of each fiscal year and whenever a plan is determined to qualify for a remeasurement. The remaining components of pension and other postretirement benefits expense are recorded ratably on a quarterly basis. Pension and other postretirement benefits adjustments charged directly to cost of sales that are applicable to inactive participants are excluded from inventoriable costs. 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 to Unallocated and other. Foreign currency translation Operations outside the United States are measured primarily using the local currency as the functional currency. Upon consolidation, the results of operations of the subsidiaries and affiliates whose functional currency is other than the U.S. dollar are translated into U.S. dollars at the average exchange rates for the year while assets and liabilities are translated at year-end exchange rates. Adjustments to translate assets and liabilities into U.S. dollars are recorded in the stockholders’ equity section of the Consolidated Balance Sheets as a component of accumulated other comprehensive income and are included in net earnings only upon sale or substantial liquidation of the underlying foreign subsidiary or affiliated company. Stock incentive plans Ashland recognizes compensation expense for stock incentive plans awarded to key employees and directors, primarily in the form of stock appreciation rights (SARs), restricted stock and restricted stock units, performance shares and other non-vested stock awards, that are generally based upon the grant-date fair value over the appropriate vesting period. Ashland utilizes several industry accepted valuation models to determine the fair value. For further information concerning stock incentive plans, see Note Q. Earnings per share The following is the computation of basic and diluted earnings per share (EPS) from continuing operations attributable to Ashland. Earnings per share are reported under the treasury stock method. Stock options and SARs for each reported year whose grant price was greater than the market price of Ashland Common Stock at the end of each fiscal year 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 1.2 million for 2016, 0.7 million for 2015 and 0.6 million for 2014.
New accounting pronouncements In August 2016, the FASB issued new accounting guidance on eight specific cash flow classification issues. The amendments in this guidance will become effective retrospectively for Ashland on October 1, 2018. Early adoption is permitted in any interim or annual period. Ashland is currently evaluating the impact this guidance may have on Ashland’s Consolidated Financial Statements. In March 2016, the FASB issued new accounting guidance for certain aspects of share-based payments to employees. This guidance requires all excess tax benefits and tax deficiencies related to share-based payments to be recognized as income tax expense in the income statement instead of additional paid in capital, and changes the classification of excess tax benefits from a financing activity to an operating activity within the statement of cash flows. This guidance also allows entities to make an accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. Lastly, this guidance increases the amount an employer can withhold to cover income taxes on awards and still qualify for equity classification and requires that cash paid by an employer when directly withholding shares for tax-withholding purposes be classified as a financing activity within the statement of cash flows. The guidance will become effective for Ashland on October 1, 2017. Ashland is currently evaluating the impact this guidance may have on Ashland’s Consolidated Financial Statements. 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 rights and obligations created by leases and to disclose key information about leasing arrangements. The presentation of the statements of comprehensive income and the statements of 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. Ashland is currently evaluating the impact this guidance may have on Ashland’s Consolidated Financial Statements. In January 2016, the FASB issued accounting guidance related to the recognition and measurement of financial assets and financial liabilities. The main objective of this guidance is enhancing the reporting model for financial instruments to provide users of financial statements with more decision-useful information. The amendments in this guidance address certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The guidance also eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet and clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The guidance will become effective for Ashland on October 1, 2018. Early application to financial statements of fiscal years or interim periods that have not yet been issued is permitted as of the beginning of the fiscal year of adoption. Ashland is currently evaluating the impact this guidance may have on Ashland’s Consolidated Financial Statements. In November 2015, the FASB issued accounting guidance requiring all deferred tax assets and liabilities to be classified as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. During 2016, Ashland adopted this new guidance and applied it retrospectively to the September 30, 2015 Consolidated Balance Sheet. The impact of this new guidance within this statement resulted in the reclassification of net current deferred taxes of $149 million with an increase to noncurrent deferred tax assets of $145 million and a decrease to noncurrent deferred tax liabilities of $4 million. In July 2015, the FASB issued accounting guidance to simplify the subsequent measurement of certain inventories by replacing the current lower of cost or market test with a lower of cost and net realizable value test. The guidance applies only to inventories for which cost is determined by methods other than last-in first-out and the retail inventory method. This guidance will become effective prospectively for Ashland on October 1, 2017, with early adoption permitted. Ashland is currently evaluating the new accounting standard and the impact this new guidance will have on Ashland’s Consolidated Financial Statements. In April 2015, the FASB issued accounting guidance to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement. Cloud computing arrangements represent the delivery of hosted services over the internet which includes software, platforms, infrastructure and other hosting arrangements. Under the guidance, customers that gain access to software in a cloud computing arrangement account for the software as internal-use software only if the arrangement includes a software license. This guidance will become effective prospectively for Ashland on October 1, 2016. In April 2015 and August 2015, the FASB issued accounting guidance to simplify the presentation of debt issuance costs by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs were not affected by this amendment. The adoption of the new guidance was on a retrospective basis. As a result of Ashland electing to early adopt this guidance during 2015, $28 million of debt issuance costs was presented as long-term debt as of September 30, 2015. 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 supersedes most current revenue recognition guidance, in an effort to converge the revenue recognition principles within U.S. GAAP. This new guidance also requires 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 have the option of using a full retrospective or a modified retrospective approach to adopt the new guidance. This guidance becomes effective for Ashland on October 1, 2018. Ashland is currently evaluating the new accounting standard and the available implementation options the standard allows as well as the impact this new guidance will have on Ashland’s Consolidated Financial Statements. In April 2014, the FASB issued accounting guidance amending the requirements for reporting discontinued operations (ASC 205 Presentation of Financial Statements and ASC 360 Property, Plant and Equipment). This guidance limits the requirement for discontinued operations treatment to the disposal of a component of an entity, or a group of components of an entity, that represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. Additionally, this new guidance no longer precludes discontinued operations presentation based on continuing involvement or cash flows following the disposal. Ashland adopted this guidance on October 1, 2014, which is applicable only to divestitures subsequent to the adoption date, and has evaluated each divestiture during the current and prior years under this new guidance. |

| Valvoline Disclosure [Abstract] | |
| VALVOLINE | Ashland Separation of Valvoline On September 22, 2015, Ashland announced that the Board of Directors approved proceeding with a plan to separate Ashland into two independent, publicly traded companies comprising of the new Ashland (now known as Ashland Global Holdings Inc.) and Valvoline Inc. The initial step of the separation, the initial public offering of Valvoline Inc., closed on September 28, 2016. The new Ashland is a premier global leader in providing specialty chemical solutions to customers in a wide range of consumer and industrial markets. These markets are currently served by Specialty Ingredients and Performance Materials. Key markets and applications include pharmaceutical, personal care, food and beverage, architectural coatings, adhesives, automotive, construction and energy. Valvoline Inc., a controlled subsidiary, operates on a stand-alone basis as a premium consumer-branded lubricant supplier. On September 22, 2016, Ashland and Valvoline Inc. announced the pricing of an initial public offering (IPO) of 30 million shares of Valvoline Inc.’s common stock at a price to the public of $22.00 per share and closed the IPO on September 28, 2016. The underwriters exercised an option to purchase an additional 4.5 million shares of Valvoline Inc.’s common stock to cover over-allotments. After completing the IPO, Ashland now owns 170 million shares of Valvoline Inc.’s common stock, representing approximately 83% of the total outstanding shares of Valvoline Inc.’s common stock. Valvoline Inc.’s common stock is listed on the New York Stock Exchange under the symbol “VVV”. Ashland presently intends to distribute the remaining Valvoline Inc. shares in 2017 following the release of March-quarter earnings results by both Ashland and Valvoline Inc. During September 2016, the total net proceeds after deducting underwriters’ discount and other offering expenses received from the IPO were $712 million. These net proceeds were used primarily to repay debt incurred prior to the IPO and retained for Valvoline Inc.’s cash on hand. See further discussion in Note J regarding certain financing related activities executed for both Ashland and Valvoline in connection with the separation process. During 2016, Ashland recognized separation costs of $88 million, which are primarily related to transaction and legal fees. Separation costs are primarily recorded within the selling, general and administrative expense caption of the Statements of Consolidated Comprehensive Income. Transferring of Assets and Liabilities As of September 30, 2016, Valvoline Inc. includes substantially all of the Valvoline business as historically reported by Ashland, as well as certain other assets and liabilities transferred to Valvoline Inc. by Ashland as a part of the separation process. The largest transferred liabilities are the net pension and other postretirement plan liabilities, which include a substantial portion of the largest U.S. qualified pension plan and non-qualified U.S. pension plans. As of September 30, 2016, Valvoline Inc.’s net pension and other postretirement plan liabilities totaled approximately $900 million. Other transferred assets and liabilities primarily consist of deferred compensation, certain Ashland legacy business insurance reserves, tax attributes and certain trade payables. The impact of these other transferring assets and liabilities was approximately $15 million of net assets. Additionally, any deferred tax assets and liabilities that relate specifically to these assets and liabilities have been transferred to Valvoline Inc. as well as certain other tax liabilities as a result of the Tax Matters Agreement. For purposes of Ashland’s 2016 segment reporting and consistent with prior periods, these transferred assets and liabilities remain included within Unallocated and other. Noncontrolling Interest As a result of the Valvoline Inc. IPO, the outside stockholders’ interests in Valvoline Inc., which was approximately 17% as of September 30, 2016, are presented separately as a noncontrolling interest within Ashland’s equity in the Consolidated Balance Sheet. As of September 30, 2016, the noncontrolling interest was $182 million. The amount of consolidated net income attributable to these minority holders is presented as a separate caption on the Statement of Consolidated Comprehensive Income. The following represents Valvoline acquisition and divestiture activity. Acquisition Oil Can Henry’s On December 11, 2015, Ashland announced that it signed a definitive agreement to acquire OCH International, Inc. (Oil Can Henry’s), which was the 13th largest quick-lube network in the United States, servicing approximately 1 million vehicles annually with 89 quick-lube stores, consisting of 47 company-owned stores and 42 franchise locations, in Oregon, Washington, California, Arizona, Idaho and Colorado. On February 1, 2016, Ashland completed the acquisition. The acquisition of Oil Can Henry’s was valued at $72 million, which included acquired indebtedness of $11 million and other working capital adjustments. Net of acquired indebtedness and certain purchase price adjustments, the net cash outlay was $62 million during 2016. The purchase price allocation primarily included $83 million of goodwill. Divestitures Valvoline Car Care Products In April 2015, Ashland entered into a definitive sale agreement to sell Valvoline’s car care product assets for $24 million, which included Car Brite™ and Eagle One™ automotive appearance products. Prior to the sale, Ashland recognized a loss of $26 million before tax in 2015 to recognize the assets at fair value less cost to sell, using Level 2 nonrecurring fair value measurements. The loss was reported within the net gain (loss) on divestitures caption within the Statements of Consolidated Comprehensive Income. The transaction closed on June 30, 2015 and Ashland received net proceeds of $19 million after adjusting for certain customary closing costs and final working capital totals. The sale of Valvoline’s car care product assets did not qualify for discontinued operations treatment since it did not represent a strategic shift that had or will have a major effect on Ashland’s operations and financial results. Valvoline Joint Venture During April 2015, Ashland sold a Valvoline joint venture equity investment in Venezuela. Prior to the sale, Ashland recognized a $14 million impairment in 2015, for which there was no tax effect, using Level 2 nonrecurring fair value measurements within the equity and other income caption of the Statements of Consolidated Comprehensive Income. Ashland’s decision to sell the equity investment and the resulting charge recorded in the prior year was reflective of the continued devaluation of the Venezuelan currency (bolivar) based on changes to the Venezuelan currency exchange rate mechanisms during the fiscal year. In addition, the continued lack of exchangeability between the Venezuelan bolivar and U.S. dollar had restricted the joint venture’s ability to pay dividends and obligations denominated in U.S. dollars. These exchange regulations and cash flow limitations, combined with other recent Venezuelan regulations and the impact of declining oil prices on the Venezuelan economy, had significantly restricted Ashland’s ability to conduct normal business operations through the joint venture arrangement. Ashland determined this divestiture did not represent a strategic shift that had or will have a major effect on Ashland’s operations and financial results, and thus it did not qualify for discontinued operations treatment. |

| ACQUISITIONS AND DIVESTITURES [Abstract] | |
| ACQUISITIONS AND DIVESTITURES [Text Block] | Acquisition Zeta Fraction™ In September 2015, Specialty Ingredients completed the acquisition of the patented Zeta Fraction™ technology from AkzoNobel for $8 million. The acquisition broadens Ashland’s value-added portfolio in the personal care, pharmaceutical, food and beverage, and agriculture markets. The patented Zeta Fraction™ process and technology selectively isolates efficacious components from living plants and marine sources to produce a wide range of biofunctional ingredients. The purchase price allocation primarily included intellectual property and property, plant and equipment. Divestitures Specialty Ingredients Joint Venture During September 2016, Ashland entered into a definitive sale agreement to sell its ownership interest in a Specialty Ingredients consolidated joint venture. Ashland recognized a loss of $12 million before tax in 2016 to recognize the assets at fair value less cost to sell, using Level 2 nonrecurring fair value measurements. The loss was reported within the net gain (loss) on divestitures caption within the Statement of Consolidated Comprehensive Income. The net assets held for sale are not material to Ashland’s Consolidated Balance Sheets. Ashland determined this transaction did not qualify for discontinued operations treatment since it did not represent a strategic shift that had or will have a major effect on Ashland’s operations and financial results. Any additional gain or loss recognized as a result of the transaction is expected to be nominal and would be recognized in the period incurred. Industrial Biocides During May 2015, Ashland entered into a definitive sale agreement to sell the industrial biocides assets within Specialty Ingredients, which closed on July 1, 2015. As a result of the sale, Ashland received net cash proceeds of approximately $30 million during the fourth quarter of 2015 and recognized a nominal gain before tax and after customary closing costs within the net gain (loss) on divestitures caption within the Statements of Consolidated Comprehensive Income. The sale of Specialty Ingredients’ industrial biocides assets did not qualify for discontinued operations treatment since it did not represent a strategic shift that had or will have a major effect on Ashland’s operations and financial results. MAP Transaction As part of the 2005 transfer of Ashland’s 38% interest in the Marathon Ashland Petroleum LLC (MAP) joint venture and two other small businesses to Marathon Oil Corporation (Marathon) (the MAP Transaction), Marathon is entitled to the tax deductions for Ashland’s future payments of certain contingent liabilities, including asbestos liabilities, related to previously owned businesses of Ashland. Marathon agreed to compensate Ashland for these tax deductions and Ashland established a discounted receivable, which represented the estimated present value of probable recoveries from Marathon for the portion of their future tax deductions. As a result of the January 2015 asbestos insurance settlement, Ashland recorded a $7 million charge during 2015 within the net gain (loss) on divestitures caption of the Statements of Consolidated Comprehensive Income. The total MAP receivable remaining as of September 30, 2016 was $8 million. See Note O for more information related to the January 2015 asbestos insurance settlement. Elastomers On October 9, 2014, Ashland entered into a definitive agreement to sell the Elastomers division of the Performance Materials reportable segment, which operated a 250-person manufacturing facility in Port Neches, Texas, to Lion Copolymer Holdings, LLC. The Elastomers division, which primarily served the North American replacement tire market, accounted for approximately 5% of Ashland’s 2014 sales of $6.1 billion and 18% of Ashland Performance Materials’ $1.6 billion in sales in 2014. The sale was completed on December 1, 2014 in a transaction valued at approximately $120 million which was subject to working capital adjustments. The total post-closing adjusted cash proceeds received before taxes by Ashland during 2015 was $105 million, which included working capital adjustments and transaction costs, as defined in the definitive agreement. Elastomers’ net assets as of November 30, 2014 were $191 million which primarily included accounts receivable, inventory, property, plant and equipment, non-deductible goodwill and other intangibles and payables. Since the net proceeds received were less than book value, Ashland recorded a loss of $86 million pre-tax, using Level 2 nonrecurring fair value measurements, within the net gain (loss) on divestitures caption of the Statements of Consolidated Comprehensive Income during 2015. The related tax effect was a benefit of $28 million included in the income tax expense (benefit) caption within the Statements of Consolidated Comprehensive Income. Ashland determined that the sale of Elastomers did not represent a strategic shift that had or will have a major effect on Ashland’s operations and financial results. As such, Elastomers’ results were included in the Performance Materials reportable segment results of operations and financial position within the Statements of Consolidated Comprehensive Income and Consolidated Balance Sheets, respectively, until its December 1, 2014 sale. Certain indirect corporate costs of $11 million for 2015 were included within the selling, general and administrative expense caption of the Statements of Consolidated Comprehensive Income that were previously allocated to the Elastomers division. Water Technologies On July 31, 2014, Ashland sold the Water Technologies business to a fund managed by Clayton, Dubilier & Rice (CD&R) in a transaction valued at approximately $1.8 billion. The total post-closing adjusted cash proceeds received by Ashland during 2014, before taxes, was $1.6 billion, which includes estimates for certain working capital and other post-closing adjustments, as defined in the definitive agreement. Ashland recognized a gain of $92 million after tax, which is included within the discontinued operations caption in the Statement of Consolidated Comprehensive Income for 2014. During 2015, Ashland received $48 million of delayed purchase price funds related to a foreign entity which completed certain regulatory closing requirements. Final settlement of working capital and other post-closing adjustments occurred during 2015 resulting in a payment of approximately $20 million to CD&R. Since this transaction signified Ashland’s exit from the Water Technologies business, Ashland has classified Water Technologies’ results of operations and cash flows within the Statements of Consolidated Comprehensive Income and Statements of Consolidated Cash Flows as discontinued operations for prior periods presented. Certain indirect corporate costs included within the selling, general and administrative expense caption of the Statements of Consolidated Comprehensive Income that were previously allocated to the Water Technologies reportable segment did not qualify for classification within discontinued operations. These costs were $31 million during 2014. Ashland retained and agreed to indemnify CD&R for certain liabilities of the Water Technologies business arising prior to the closing of the sale, including certain pension and postretirement liabilities, environmental remediation liabilities and certain legacy liabilities relating to businesses disposed or discontinued by the Water Technologies business. Costs directly related to these retained liabilities have been included within the discontinued operations caption of the Statements of Consolidated Comprehensive Income. The ongoing effects of the pension and other postretirement plans for former Water Technologies employees are reported within the Unallocated and other segment. Ashland provided certain transition services to CD&R for a fee. During 2016, 2015 and 2014, Ashland recognized transition service fees of $5 million, $28 million and $7 million, respectively, within the selling, general and administrative expense caption of the Statements of Consolidated Comprehensive Income. While the transition services vary in duration depending upon the type of service provided, Ashland continued to reduce costs as the transition services were completed. See Note D for further information on the results of operations of Water Technologies for all periods presented. Casting Solutions joint venture During 2014, Ashland, in conjunction with its partner, initiated a process to sell the ASK Chemicals GmbH (ASK) joint venture, in which Ashland had 50% ownership. As part of the sale process, Ashland determined during 2014 that the fair value of its investment in the ASK joint venture was less than the carrying value and that an other than temporary impairment had occurred. As a result, Ashland recognized an impairment charge of $50 million related to its investment in the ASK joint venture. The charge was recognized within the equity and other income caption of the Statements of Consolidated Comprehensive Income. On June 30, 2014, Ashland, in conjunction with its partner, sold the ASK joint venture to investment funds affiliated with Rhône Capital, LLC (Rhône), a London and New York-based private equity investment firm. From the sale, total pre-tax proceeds to the sellers, which were split evenly between Ashland and its partner, under the terms of the 50/50 joint venture, were $205 million, which included $176 million in cash and a $29 million note from Rhône due in calendar year 2022. |

| Discontinued Operations and Disposal Groups [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 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 for all periods presented and are discussed further within this note. Ashland is subject to liabilities from claims alleging personal injury caused by exposure to asbestos. Such claims result primarily from indemnification obligations undertaken in 1990 in connection with the sale of Riley, a former subsidiary, which qualified as a discontinued operation and from the acquisition during 2009 of Hercules, an indirect wholly-owned subsidiary of Ashland. Adjustments to the recorded litigation reserves and related insurance receivables are recorded within the discontinued operations caption and continue periodically. During 2015, Ashland recorded an after-tax gain of $120 million within discontinued operations due to the January 2015 asbestos insurance settlement. See Note O for further discussion of Ashland’s asbestos-related activity. As previously described in Note C, on July 31, 2014, Ashland completed the sale of the Water Technologies business to CD&R. Sales recognized for the ten month period Water Technologies was still owned by Ashland in 2014 were $1.5 billion. The previous results of operation related to Water Technologies have been reflected as discontinued operations in the Statements of Consolidated Comprehensive Income. Ashland made subsequent post-closing adjustments to the discontinued operations caption in 2016, 2015 and 2014. On March 31, 2011, Ashland completed the sale to Nexeo Solutions, LLC of substantially all of the assets and certain liabilities of its global distribution business, which previously comprised the Ashland Distribution (Distribution) reportable segment. Ashland determined that this sale qualified as a discontinued operation, in accordance with U.S. GAAP, since Ashland does not have significant continuing involvement in the Distribution business. Ashland made subsequent adjustments to the discontinued operations caption for Distribution during 2015. On August 28, 2006, Ashland completed the sale of the stock of Ashland Paving And Construction, Inc. (APAC) for $1.3 billion. The sale qualified as a discontinued operation, and as a result, the previous operating results related to APAC have been reflected as discontinued operations in the Statements of Consolidated Comprehensive Income. Ashland has made subsequent adjustments to the gain on the sale of APAC, primarily relating to the tax effects of the sale, during 2015 and 2014. Due to the ongoing assessment of certain matters associated with previous divestitures, subsequent adjustments to these divestitures may continue in future periods in the discontinued operations caption in the Statements of Consolidated Comprehensive Income. Components of amounts reflected in the Statements of Consolidated Comprehensive Income related to discontinued operations are presented in the following table for each of the years ended September 30.

| Restructuring and Related Activities [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 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 for each business. Severance costs During 2014, Ashland announced a global restructuring program to streamline the resources used across the organization. As part of this global restructuring program, Ashland executed a voluntary severance offer (VSO) to certain U.S. employees and an involuntary program for certain employees. Substantially all payments related to the VSO and involuntary programs were paid by the end of fiscal year 2015. The VSO and involuntary programs resulted in expense of $95 million being recognized during 2014, with $13 million being recorded within the cost of sales caption and $82 million being recorded within the selling, general and administrative expense caption of the Statements of Consolidated Comprehensive Income. In addition, the employee reductions resulted in a pension curtailment being recorded during 2014. See Note N for further information. As of September 30, 2015, the remaining restructuring reserve for the global restructuring program was $7 million and was fully paid during 2016. Additional restructuring reserves of $1 million for other previously announced programs also remained as of September 30, 2016 and 2015. Facility costs In prior years, Ashland incurred lease abandonment charges related to its exit from office facilities obtained as part of the Hercules acquisition. During 2014, Ashland incurred an additional $4 million lease abandonment charge related to its exit from a Hercules related office facility. As of September 30, 2015, the remaining restructuring reserve for all qualifying facility costs totaled $3 million. During 2016, all remaining lease payments were made, reducing the reserve to zero as of September 30, 2016. The following table details at September 30, 2016, 2015 and 2014, the amount of restructuring reserves related to the programs discussed above, and the related activity in these reserves during 2016, 2015 and 2014. The severance reserves are included in accrued expenses and other liabilities in the Consolidated Balance Sheets for all periods presented. As of September 30, 2015, facility cost reserves were included in accrued expenses and other liabilities in the Consolidated Balance Sheet, while these reserves were primarily within other noncurrent liabilities as of September 30, 2014.
Specialty Ingredients Restructuring During 2015, Specialty Ingredients committed to a restructuring plan within an existing manufacturing facility. As a result, restructuring charges of $23 million were recorded within the cost of sales caption of the Statements of Consolidated Comprehensive Income. As of September 30, 2015, the remaining restructuring reserve related to severance for the Specialty Ingredients manufacturing facility totaled $13 million. During 2016, the severance reserve was reduced by a $5 million reversal of the accrual, as well as reclassifications of certain non-severance related costs, and was fully paid as of September 30, 2016. The severance reserve was included in accrued expenses and other liabilities in the Consolidated Balance Sheets. |

| 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 through the use of 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 September 30, 2016. For additional information on fair value hierarchy measurements of pension plan asset holdings, see Note N.
The following table summarizes financial instruments subject to recurring fair value measurements as of September 30, 2015.
Restricted investments As discussed in Note A, Ashland maintains certain investments in a restricted renewable annual trust for the purpose of paying future asbestos indemnity and defense costs. The investments are designated as available-for-sale securities, classified as Level 1 measurements within the fair value hierarchy. These securities were classified primarily as noncurrent restricted investment assets, with $30 million classified within other current assets, in the Consolidated Balance Sheets. The following table provides a summary of the activity within the available-for-sale securities portfolio as of September 30, 2016 and 2015:
(a) The adjusted cost in September 30, 2016 represents the carrying value of the demand deposit and the adjusted cost of the equity and corporate bond mutual funds as of September 30, 2015.
The following table presents gross unrealized gains and losses for the available-for-sale securities as of September 30, 2016 and 2015:
The unrealized gains and losses as of September 30, 2016 and 2015 were recognized within accumulated other comprehensive income (AOCI). Ashland invests in highly-rated investment grade mutual funds. No realized gain or loss was reclassified out of AOCI and no other-than-temporary impairment was recognized in AOCI during 2016 and 2015. Deferred compensation investments Deferred compensation investments consist of Level 1 and Level 2 measurements within the fair value hierarchy. Level 1 investments consist primarily of fixed income U.S. government bonds while Level 2 investments are comprised primarily of a guaranteed interest fund, a common stock index fund and an intermediate government bond fund. Gains and losses related to deferred compensation investments are immediately recognized within the Statements of Consolidated Comprehensive Income. Derivative and hedging activities Currency hedges 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 of 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 gains and losses recognized during 2016, 2015 and 2014 within the Statements of Consolidated Comprehensive Income.
The following table summarizes the fair values of the outstanding foreign currency derivatives as of September 30, 2016 and 2015 included in accounts receivable and accrued expenses and other liabilities of the Consolidated Balance Sheets.
Net investment hedges Since 2014, Ashland has entered into foreign currency contracts in order to manage the foreign currency exposure of the net investment in certain foreign operations. These foreign currency contracts were primarily the result of certain proceeds from the sale of Water Technologies being received in non-U.S. denominated currencies during 2014 and ongoing management of the volatility in foreign currency exchange rates. Ashland designated the foreign currency contracts as hedges of net investments in its foreign subsidiaries. As a result, Ashland records these hedges at fair value using forward rates, with the effective portion of the gain or loss reported as a component of the cumulative translation adjustment within AOCI and subsequently recognized in the Statements of Consolidated Comprehensive Income when the hedged item affects net income. During 2016 and 2015, these foreign currency contracts were settled and Ashland entered into new foreign currency contracts designated as hedges of net investments in foreign subsidiaries. These settlements resulted in net gains recorded within the cumulative translation adjustment within AOCI of $4 million and $11 million during 2016 and 2015, respectively. As of September 30, 2016 and 2015, the total notional value of foreign currency contracts equaled $94 million and $175 million, respectively. The fair value of Ashland’s net investment hedge assets and liabilities are calculated using forward rates. Accordingly, these instruments are deemed to be Level 2 measurements within the fair value hierarchy. Counterparties to these net investment hedges are highly rated financial institutions which Ashland believes carry only a nominal risk of nonperformance. The following table summarizes the fair value of the outstanding net investment hedge instruments as of September 30, 2016 and 2015.
The following table summarizes the change in the unrealized gain (loss) on the net investment hedge instruments recognized within the cumulative translation adjustment within AOCI during 2016 and 2015. No portion of the gain or loss was reclassified to income during 2016 and 2015. There was no hedge ineffectiveness with these instruments during 2016 and 2015.
Other financial instruments At September 30, 2016 and 2015, Ashland’s long-term debt (including current portion and excluding debt issuance cost discounts) had a carrying value of $3,103 million and $3,431 million, respectively, compared to a fair value of $3,336 million and $3,484 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 | 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. Ashland determined that its reporting units for the allocation of goodwill include the Specialty Ingredients reportable segment, the Composites and Intermediates/Solvents reporting units within the Performance Materials reportable segment, and the Core North America, Quick Lubes and International reporting units within the Valvoline reportable segment. In the first step of the impairment model, Ashland compares the carrying value of each reporting unit to its respective estimated fair value. Ashland makes various estimates and assumptions in determining the estimated fair values of those units through the use of a combination of discounted cash flow models and valuations based on earnings multiples for guideline public companies in each reporting unit’s industry peer group. Discounted cash flow models are highly reliant on various assumptions. Significant assumptions Ashland utilized in these models for the current year included: projected business results and future industry direction, long-term growth factors and weighted-average cost of capital. Ashland uses assumptions that it deems to be reasonable estimates of likely future events and compares the total fair values of each reporting unit to Ashland’s market capitalization, and implied control premium, to determine if the fair values are reasonable compared to external market indicators. Subsequent changes in these key assumptions could affect the results of future goodwill impairment reviews. In conjunction with the July 1, 2016 annual assessment of goodwill, Ashland’s valuation techniques did not indicate any impairment for Specialty Ingredients, Composites, Core North America, Quick Lubes or International. Due to deterioration in the butanediol commodity market during 2016 in which the Intermediates/Solvents reporting unit operates (and the impact thereof on Ashland’s most recently completed three-year business plan), Ashland determined that the carrying value of the Intermediates/Solvents reporting unit exceeded its fair value at July 1, 2016, which resulted in the reporting unit failing the first step of the goodwill impairment test. Ashland then performed the second step of the goodwill impairment test, which involved, among other things, obtaining third-party appraisals of substantially all of Intermediates/Solvents tangible and intangible assets. Based on the results of its goodwill impairment testing as of July 1, 2016, Ashland recorded a pre-tax goodwill impairment charge of $171 million in the fourth quarter of 2016, which is in addition to a $10 million impairment related to Intermediates/Solvents property, plant and equipment, resulted in a total $181 million impairment charge for Intermediates/Solvents during 2016. A portion of the goodwill impairment was nondeductible. Ashland’s assessment of an impairment charge on any of these remaining assets currently classified as having indefinite lives, including goodwill, could result in additional impairment charges in future periods if any or all of the following events were to occur with respect to a particular reporting unit: a significant change in projected business results, a divestiture decision, increase in Ashland’s weighted-average cost of capital rates, decrease in growth rates or other assumptions, economic deterioration that is more severe or of a longer duration than anticipated, or another significant economic event. The following is a progression of goodwill by reportable segment for the years ended September 30, 2016 and 2015.
Other intangible assets Intangible assets principally consist of trademarks and trade names, intellectual property, customer relationships and in-process research and development (IPR&D). 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 20 years and customer relationships over 3 to 24 years. During 2015 and 2014, there was impairments of certain IPR&D assets associated with the acquisition of International Specialty Products Inc. (ISP) of $11 million and $13 million, respectively, which were classified within the research and development expense caption of the Statements of Consolidated Comprehensive Income. These impairments represented Level 2 nonrecurring fair value measurements. As of September 30, 2015, IPR&D and certain intangible assets within trademarks and tradenames were classified as indefinite-lived and had a balance of $311 million. During 2016, Ashland started amortizing the remaining IPR&D assets since the technology was commercialized during this period. As a result, as of September 30, 2016, the indefinite-lived intangible assets consisted only of certain trademarks and trade names of $301 million. 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. In conjunction with the July 1, 2016 annual assessment of indefinite-lived intangible assets, Ashland’s models did not indicate any additional impairment for indefinite-lived intangible assets. Intangible assets were comprised of the following as of September 30, 2016 and 2015.
Amortization expense recognized on intangible assets was $77 million for 2016, $78 million for 2015 and $89 million for 2014, and is primarily included in the selling, general and administrative expense caption of the Statements of Consolidated Comprehensive Income. As of September 30, 2016, all of Ashland’s intangible assets that had a carrying value were being amortized except for certain trademarks and trade names that have been determined to have indefinite lives. Estimated amortization expense for future periods is $76 million in 2017, $76 million in 2018, $72 million in 2019, $71 million in 2020 and $70 million in 2021. 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. |

| DEBT | The following table summarizes Ashland’s current and long-term debt at September 30, 2016 and 2015.
At September 30, 2016, Ashland’s total debt had an outstanding principal balance of $3,419 million, discounts of $146 million and debt issuance costs of $29 million. The scheduled aggregate maturities of long-term debt for the next five fiscal years (including the current portion and excluding debt issuance costs) are as follows: $19 million in 2017, $719 million in 2018, $43 million in 2019, $38 million in 2020 and $263 million in 2021. Ashland Financing Activities Senior notes refinancing, 2015 Senior Credit Agreement and 2016 Amendment During June of 2015, Ashland completed certain refinancing transactions related to the $600 million 3.000% senior notes due in 2016 (2016 senior notes). Ashland commenced and completed a cash tender offer to purchase for cash any and all of its outstanding 2016 senior notes. At the close of the tender offer, $550 million aggregate principal amount of the 2016 senior notes was tendered by note holders, representing approximately 92% of the outstanding 2016 senior notes, which have been purchased by Ashland. Subsequently, Ashland redeemed the remaining balance of the 2016 senior notes of $50 million on July 23, 2015. In connection with the tender offer and redemption, in June 2015, Ashland entered into a new Credit Agreement (the 2015 Senior Credit Agreement). The 2015 Senior Credit Agreement replaced the $1.2 billion senior unsecured revolving credit facility (the 2013 Senior Credit Facility), and was comprised of a new five-year senior unsecured revolving credit facility in an aggregate amount of $1.2 billion (the 2015 revolving credit facility), which includes a $250 million letter of credit sublimit and a $100 million swing line loan sublimit, and a five-year senior unsecured term loan facility in an aggregate principal amount of $1.1 billion (the 2015 term loan facility). The 2015 Senior Credit Agreement is not guaranteed, is unsecured and can be prepaid at any time without premium or penalty. At Ashland’s option, borrowings under the 2015 revolving credit facility bear interest at either LIBOR or an alternate base rate, in each case plus the applicable interest rate margin. The loans’ interest rate fluctuate between LIBOR plus 1.375% per annum and LIBOR plus 2.50% per annum (or between the alternate base rate plus 0.375% per annum and the alternate base rate plus 1.50% per annum), based upon Ashland’s corporate credit ratings or the consolidated gross leverage ratio (as defined in the 2015 Senior Credit Agreement) (whichever yields a lower applicable interest rate margin) at such time. In addition, Ashland was required to pay fees of 0.25% per annum on the daily unused amount of the 2015 revolving credit facility through and including June 30, 2015, and thereafter the fee rate will fluctuate between 0.175% and 0.40% per annum, based upon Ashland’s corporate credit ratings or the consolidated gross leverage ratio (whichever yields a lower fee rate). During 2015, Ashland used the proceeds from borrowings under the $1.1 billion term loan facility along with cash on hand (i) to fund the tender offer of the 2016 senior notes, (ii) to prepay in full the outstanding loans under the 2013 Senior Credit Facility, (iii) to pay accrued interest, fees and expenses under the 2013 Senior Credit Facility and the 2016 senior notes, (iv) to contribute funds to the U.S. pension plans impacted by the pension plan settlement program discussed in Note N, and (v) to pay fees and expenses incurred in connection with the entry into the 2015 Senior Credit Agreement. As a result of the tender offer and redemption, Ashland recognized a $9 million charge related to early redemption premium payments, which is included in the net interest and other financing expense caption of the Statements of Consolidated Comprehensive Income in 2015. Ashland incurred $10 million of new debt issuance costs in connection with the 2015 Senior Credit Agreement, of which $2 million was recognized immediately during 2015 within the net interest and other financing expense caption of the Statements of Consolidated Comprehensive Income. The remaining balance is amortized over the term of the 2015 Senior Credit Agreement using the effective interest method. Additionally, as a result of the termination of the 2013 Senior Credit Facility and the repayment of the 2016 senior notes, Ashland recognized a $2 million charge during 2015 for the accelerated amortization of previously capitalized debt issuance costs, which is included in the net interest and other financing expense caption of the Statements of Consolidated Comprehensive Income. During July 2016, Ashland amended the 2015 Senior Credit Agreement to permit the Reorganization and the series of events relating to the separation of Valvoline Inc. Additionally, the amendment provided that if the aggregate principal amount of the Valvoline debt reaches $750 million, Ashland would be required to use the net proceeds of such borrowings to repay the 2015 term loan facility and/or permanently reduce its existing revolving credit commitments under the 2015 Senior Credit Agreement in an aggregate amount of up to $1 billion. As a result of the July 2016 amendment and the Valvoline debt borrowings in connection with the separation, Ashland reduced its revolving borrowing capacity to $800 million as of September 30, 2016. The 2015 term loan facility balance was repaid in full in connection with the combined Ashland and Valvoline financing activities during September 2016. In connection with these transactions, Ashland recognized a $6 million charge for the accelerated amortization of previously capitalized debt issuance costs, which is included in the net interest and other financing expense caption of the Statements of Consolidated Comprehensive Income. Total borrowing capacity remaining under the 2015 revolving credit facility was $742 million due a reduction of $58 million for letters of credit outstanding at September 30, 2016. Parent Guarantee of 4.750% notes due 2022, 3.875% notes due 2018 and 6.875% notes due 2043 On October 20, 2016, Ashland received the requisite consents with respect to its consent solicitation from the holders of Ashland LLC’s 3.875% Senior Notes due 2018, 4.750% Senior Notes due 2022 and 6.875% Senior Notes due 2043 (the Notes) to certain amendments to the reporting covenants in the indentures governing the Notes. Following receipt of the consents, Ashland LLC, as issuer, Ashland and the trustee, entered into two supplemental indentures that (1) modify the applicable reporting covenants contained in the indentures governing the Notes to provide that so long as any parent entity of Ashland LLC guarantees the Notes, the reports, information and other documents required to be filed and furnished to holders of the Notes pursuant to the applicable indenture may, at the option of Ashland LLC, be filed by and be those of such parent entity rather than Ashland LLC and (2) provide for the guarantee of the Notes by Ashland. Subsidiary senior unsecured term loan During August 2016, a wholly owned foreign subsidiary of Ashland entered into a credit agreement which provides for an aggregate principal amount of $150 million in a senior unsecured term loan facility maturing on February 15, 2017. This term loan was drawn in full as of September 30, 2016. At the subsidiary’s option, loans issued under this term loan facility bear interest at either LIBOR plus 1.75% per annum or an alternate base rate plus 0.75% per annum. The subsidiary may prepay the term loan facility after three months from the date it was drawn upon without any premium or penalty. Accounts receivable securitization On August 31, 2012, Ashland entered into a $350 million accounts receivable securitization facility pursuant to (i) a Sale Agreement, among Ashland and certain of its direct and indirect subsidiaries (each an Originator and collectively, the Originators) and CVG Capital III LLC, a wholly-owned “bankruptcy remote” special purpose subsidiary of the Originators (CVG) and (ii) a Transfer and Administration Agreement, among CVG, each Originator, Ashland, as Master Servicer, certain Conduit Investors, Uncommitted Investors, Letter of Credit Issuers, Managing Agents, Administrators and Committed Investors, and The Bank of Nova Scotia, as agent for various secured parties (the Agent). The Transfer and Administration Agreement had a term of three years, but was extendable at the discretion of Ashland and the Investors. During 2016, the termination date of the commitments under the Transfer and Administration Agreement was extended from December 31, 2015, the previous termination extension date, to March 22, 2017. Under the Sale Agreement, each Originator will transfer, on an ongoing basis, certain of its accounts receivable, certain related assets and the right to the collections on those accounts receivable to CVG. Under the terms of the Transfer and Administration Agreement, CVG could, from time to time, obtain up to $350 million (in the form of cash or letters of credit for the benefit of Ashland and its subsidiaries) from the Conduit Investors, the Uncommitted Investors and/or the Committed Investors through the sale of an undivided interest in such accounts receivable, related assets and collections. Subsequently during 2014 and 2015, the available funding for qualifying receivables under the accounts receivable securitization facility was reduced from $350 million to $275 million during 2014 and from $275 million to $250 million during 2015 due to the divestitures that occurred during the fiscal years. The accounts receivable securitization facility was reduced from $250 million to $100 million when Valvoline was removed as an Originator as part of the combined Ashland and Valvoline financing activities in September 2016. Ashland accounts for the securitization facility as secured borrowings, and the receivables sold pursuant to the facility are included in the Consolidated Balance Sheets as accounts receivable. Fundings under the Transfer and Administration Agreement will be repaid as accounts receivable are collected, with new fundings being advanced (through daily reinvestments) as new accounts receivable are originated by the Originators and transferred to CVG, with settlement generally occurring monthly. Ashland continues to classify any borrowings under this facility as a short-term debt instrument within the Consolidated Balance Sheets. Once sold to CVG, the accounts receivable, related assets and rights to collection described above are separate and distinct from each Originator’s own assets and are not available to its creditors should such Originator become insolvent. Substantially all of CVG’s assets have been pledged to the Agent in support of its obligations under the Transfer and Administration Agreement. At September 30, 2016 and 2015, the outstanding amount of accounts receivable transferred by Ashland to CVG was $133 million and $381 million, respectively. There were no borrowings under the facility as of September 30, 2016, while Ashland had drawn $190 million under the facility as of September 30, 2015. The available borrowing capacity under the facility was $80 million as of September 30, 2016. The weighted-average interest rate for this instrument was 1.5% for 2016 and 1.8% for 2015. Other debt At September 30, 2016 and 2015, Ashland held other debt totaling $176 million and $175 million, respectively, comprised primarily of the 6.60% and 6.50% notes due 2027 and 2029, respectively, assumed in the Hercules acquisition, other short-term international loans, and a medium-term note. Covenants related to current Ashland debt agreements Ashland’s debt contains usual and customary representations, warranties and affirmative and negative covenants, including financial covenants for leverage and interest coverage ratios, limitations on liens, additional subsidiary indebtedness, restrictions on subsidiary distributions, investments, mergers, sale of assets and restricted payments and other customary limitations. As of September 30, 2016, Ashland was in compliance with all debt agreement covenant restrictions. The maximum consolidated leverage ratios permitted under the 2015 Senior Credit Agreement are as follows: 3.75 through December 31, 2016 and 3.5 from March 31, 2017 and each fiscal quarter thereafter. The 2015 Senior Credit Agreement defines the consolidated leverage ratio as the ratio of consolidated indebtedness minus unrestricted cash and cash equivalents to consolidated EBITDA (Covenant Adjusted EBITDA) for any measurement period. In general, the 2015 Senior Credit Agreement defines Covenant Adjusted EBITDA as net income plus consolidated interest charges, taxes, depreciation and amortization expense, fees and expenses related to capital market transactions, restructuring and integration charges, noncash stock and equity compensation expense, and any other nonrecurring expenses or losses that do not represent a cash item in such period or any future period; less any noncash gains or other items increasing net income. The computation of Covenant Adjusted EBITDA differs from the calculation of EBITDA and Adjusted EBITDA, which have been reconciled on page M-8. In general, consolidated indebtedness includes debt plus all purchase money indebtedness, banker’s acceptances and bank guaranties, deferred purchase price of property or services, attributable indebtedness and guarantees. The minimum required consolidated interest coverage ratio under the 2015 Senior Credit Agreement during its entire duration is 3.0. The 2015 Senior Credit Agreement defines the consolidated interest coverage ratio as the ratio of Covenant Adjusted EBITDA to consolidated interest charges for any measurement period. At September 30, 2016, Ashland’s calculation of the consolidated leverage ratio was 2.7, which is below the maximum consolidated leverage ratio permitted under the 2015 Senior Credit Agreement of 3.75. At September 30, 2016, Ashland’s calculation of the consolidated interest coverage ratio was 3.9, which exceeds the minimum required consolidated ratio of 3.0. Valvoline Financing Activities Valvoline Credit Agreement The Valvoline Credit Agreement provides for an aggregate principal amount of $1,325 million in senior secured credit facilities (Valvoline Credit Facilities), comprised of (i) a five-year $875 million term loan A facility (the 2016 term loan facility) and (ii) a five-year $450 million revolving credit facility (the 2016 revolving credit facility) (including a $100 million letter of credit sublimit). The Valvoline Credit Facilities may be prepaid at any time without premium. The Valvoline Credit Facilities are guaranteed by Valvoline Inc.’s existing and future subsidiaries (other than certain immaterial subsidiaries, joint ventures, special purpose financing subsidiaries, regulated subsidiaries, foreign subsidiaries and certain other subsidiaries), and are secured by a first-priority security interest in substantially all the personal property assets, and certain real property assets, of Valvoline Inc. and the guarantors, including all or a portion of the equity interests of certain of Valvoline Inc.’s domestic subsidiaries and first-tier foreign subsidiaries and, in certain cases, a portion of the equity interests of other foreign subsidiaries. At Valvoline Inc.’s option, the loans issued under the Valvoline Credit Agreement will bear interest at either LIBOR or an alternate base rate, in each case plus the applicable interest rate margin. Loans initially bear interest at LIBOR plus 2.375% per annum, in the case of LIBOR borrowings, or at the alternate base rate plus 1.375%, in the alternative, through and including the date of delivery of a quarterly compliance certificate and thereafter the interest rate will fluctuate between LIBOR plus 1.500% per annum and LIBOR plus 2.500% per annum (or between the alternate base rate plus 0.500% per annum and the alternate base rate plus 1.500% per annum), based upon Valvoline Inc.’s corporate credit ratings or the consolidated first lien net leverage ratio (as defined in the Valvoline Credit Agreement) (whichever yields a lower applicable interest rate margin) at such time. During September 2016, Valvoline Inc. borrowed $875 million of principal on the 2016 term loan facility and $137 million on the 2016 revolving credit facility. The net proceeds of these borrowings of $865 million (after deducting fees and expenses) for the 2016 term loan facility and $137 million for the 2016 revolving credit facility were transferred to Ashland. With these proceeds, Ashland repaid $785 million of its 2015 loan facility, $150 million of the 2015 revolving credit facility and $45 million of its accounts receivable securitization. Valvoline Inc. used the net proceeds of its September 2016 IPO to repay $500 million of the outstanding balance under its 2016 term loan facility and all of the $137 million outstanding balance of its 2016 revolving credit facility. See Note B for more information on the IPO of Valvoline Inc. common stock. Valvoline Inc. incurred $10 million of new debt issuance costs in connection with the Valvoline Credit Agreement. These debt issuance costs were capitalized and will be amortized over the term of the Valvoline Credit Agreement using the effective interest method. Additionally, as a result of the $500 million repayment of the Valvoline 2016 term loan facility, Valvoline Inc. recognized a $4 million charge for the accelerated amortization of previously capitalized debt issuance costs, which is included in the net interest and other financing expense caption of the Statements of Consolidated Comprehensive Income. At September 30, 2016, the total borrowing capacity remaining under the 2016 revolving credit facility was $435 million due to a reduction of $15 million for letters of credit outstanding. Valvoline senior notes During July 2016, Valvoline completed its issuance of 5.500% senior unsecured notes due 2024 (2024 notes) with an aggregate principal amount of $375 million. Valvoline incurred $6 million of new debt issuance costs in connection with the issuance of the 2024 notes. These debt issuance costs were capitalized and will be amortized over the term of the 2024 notes using the effective interest method. During July 2016, the net proceeds of the offering of $370 million (after deducting initial purchasers’ discounts) were transferred to Ashland. Ashland used these proceeds to repay $110 million of the outstanding balance under Ashland’s 2015 revolving credit facility and $260 million of the 2015 term loan facility. Covenants related to current Valvoline debt agreements The Valvoline Credit Agreement contains usual and customary representations and warranties, and usual and customary affirmative and negative covenants, including limitations on liens, additional indebtedness, investments, restricted payments, asset sales, mergers, affiliate transactions and other customary limitations, as well as financial covenants (including maintenance of a maximum consolidated leverage ratio and a minimum consolidated interest coverage ratio) and other customary limitations. As of September 30, 2016, Valvoline Inc. was in compliance with all debt agreement covenant restrictions. The maximum consolidated leverage ratio permitted under the Valvoline Credit Agreement is 4.5. The Valvoline Credit Agreement defines the consolidated leverage ratio as the ratio of consolidated indebtedness minus unrestricted cash and cash equivalents to consolidated EBITDA (Covenant Adjusted EBITDA) for any measurement period. In general, the Valvoline Credit Agreement defines Covenant Adjusted EBITDA as net income plus consolidated interest charges, taxes, depreciation and amortization expense, fees and expenses related to capital market transactions, restructuring and integration charges, noncash stock and equity compensation expense, and any other nonrecurring expenses or losses that do not represent a cash item in such period or any future period; less any noncash gains or other items increasing net income. The minimum required consolidated interest coverage ratio under the Valvoline Credit Agreement during its entire duration is 3.0. The Valvoline Credit Agreement defines the consolidated interest coverage ratio as the ratio of Covenant Adjusted EBITDA to consolidated interest charges for any measurement period. At September 30, 2016, Valvoline’s calculation of the consolidated leverage ratio was 1.4, which is below the maximum consolidated leverage ratio permitted under the Valvoline Credit Agreement of 4.5. At September 30, 2016, Valvoline’s calculation of the consolidated interest coverage ratio was 13.3, which exceeds the minimum required consolidated ratio of 3.0.

| INCOME TAXES | A summary of the provision for income taxes related to continuing operations follows.
Deferred income taxes are provided for income and expense items recognized in different years for tax and financial reporting purposes. As of September 30, 2016, management intends to indefinitely reinvest approximately $1.5 billion of foreign earnings. Because these earnings are considered indefinitely reinvested, no U.S. tax provision has been accrued related to the repatriation of these earnings, and it is not practicable to estimate the amount of U.S. tax that might be payable if these earnings were ever to be remitted. Foreign net operating loss carryforwards primarily relate to certain European and Asian Pacific operations and generally may be carried forward. U.S. state net operating loss carryforwards relate to operational losses within certain states and generally may be carried forward. Temporary differences that give rise to significant deferred tax assets and liabilities as of September 30 are presented in the following table.
The U.S. and foreign components of income from continuing operations before income taxes and a reconciliation of the statutory federal income tax with the provision for income taxes follow. The foreign components of income from continuing operations disclosed in the following table exclude any allocations of certain corporate expenses incurred in the U.S.
The 2016 effective tax rate was impacted by jurisdictional income mix and net unfavorable adjustments primarily related to a nondeductible goodwill impairment for the Intermediates/Solvents division, valuation allowances for domestic attributes, accruals for unrecognized tax benefits and other items related to the separation of Valvoline. The 2015 effective tax rate was impacted by net favorable items predominantly due to certain valuation allowance releases related to state deferred tax assets. These favorable adjustments were partially offset by an accrual for an unrecognized tax benefit and tax related to certain global restructuring steps. Income tax benefit for 2014 included a $168 million tax benefit related to the reversal of deferred tax liabilities for outside basis differences and other related matters, a charge of $39 million for taxes associated with the sale of shares of subsidiaries included in the sale of the Water Technologies business, net charges of $32 million for uncertain tax positions and related matters, a charge of $14 million for a foreign income tax rate change and other net discrete item charges of $7 million primarily related to changes in valuation allowances. Unrecognized tax benefits U.S. GAAP prescribes a recognition threshold and measurement attribute for the accounting and financial statement disclosure of tax positions taken or expected to be taken in a tax return. The evaluation of a tax position is a two-step process. The first step requires Ashland to determine whether it is more likely than not that a tax position will be sustained upon examination based on the technical merits of the position. The second step requires Ashland to recognize in the financial statements each tax position that meets the more likely than not criteria, measured at the amount of benefit that has a greater than 50% likelihood of being realized. Ashland had $168 million and $144 million of unrecognized tax benefits, of which $14 million and $16 million relate to discontinued operations at September 30, 2016 and 2015, respectively. As of September 30, 2016, the total amount of unrecognized tax benefits that, if recognized, would affect the tax rate for continuing and discontinued operations was $148 million. The remaining unrecognized tax benefits relate to tax positions for which ultimate deductibility is highly certain but for which there is uncertainty as to the timing of such deductibility. Recognition of these tax benefits would not have an impact on the effective tax rate. Ashland recognizes interest and penalties related to uncertain tax positions as a component of income tax expense (benefit) in the Statements of Consolidated Comprehensive Income. Such interest and penalties totaled a $5 million expense in 2016, $1 million expense in 2015 and $2 million benefit in 2014. Ashland had $21 million and $18 million in interest and penalties related to unrecognized tax benefits accrued as of September 30, 2016 and 2015, respectively. Changes in unrecognized tax benefits were as follows:
From a combination of statute expirations and audit settlements in the next twelve months, Ashland expects a decrease in the amount of accrual for uncertain tax positions of up to $3 million for continuing operations and zero for discontinued operations. For the remaining balance as of September 30, 2016, it is reasonably possible that there could be material changes to the amount of uncertain tax positions due to activities of the taxing authorities, settlement of audit issues, reassessment of existing uncertain tax positions, or the expiration of applicable statute of limitations; however, Ashland is not able to estimate the impact of these items at this time. Ashland or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. Foreign taxing jurisdictions significant to Ashland include Australia, Canada, Spain, Switzerland, Brazil, Mexico, China, Germany, Singapore and the Netherlands. Ashland is subject to U.S. federal income tax examinations by tax authorities for periods after September 30, 2011 and U.S. state income tax examinations by tax authorities for periods after September 30, 2003. With respect to countries outside of the United States, with certain exceptions, Ashland’s foreign subsidiaries are subject to income tax audits for years after 2005. |

| EMPLOYEE BENEFIT PLANS | Pension plans Ashland and its subsidiaries sponsor contributory and noncontributory qualified defined benefit pension plans that cover certain employees in the United States and in a number of other countries. In addition, Ashland has non-qualified unfunded pension plans which provide supplemental defined benefits to those employees whose benefits under the qualified pension plans are limited by the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code. Ashland funds the costs of the non-qualified plans as the benefits are paid. Pension obligations for applicable employees of non-U.S. consolidated subsidiaries are provided for in accordance with local practices and regulations of the respective countries. Benefits for those eligible for Ashland’s U.S. pension plans generally are based on employees’ years of service and compensation during the years immediately preceding their retirement. The majority of Ashland’s U.S. pension plans have been closed to new participants since January 1, 2011 and most foreign pension plans are closed to new participants while those that remain open relate to areas where jurisdictions require plans to operate within the applicable country. During March 2016, Ashland announced plans to amend the majority of its U.S. pension plans, with the exception of certain union plans, to freeze the accrual of pension benefits for participants. The plan changes were effective September 30, 2016. During September 2016, Ashland transferred a substantial portion of the largest U.S. qualified pension and non-qualified U.S. pension plans as well as certain other postretirement obligations to Valvoline Inc. as part of the separation process discussed further in Note B. As of September 30, 2016, the net pension and other postretirement plan liabilities attributable to plans now held at Valvoline Inc. was approximately $900 million. Pension annuity program On September 15, 2016, Valvoline Inc. purchased a non-participating annuity contract with pension plan assets from Prudential Insurance Company of America (Prudential) to pay and administer future pension benefits for approximately 14,800 participants within the primary U.S. pension plan. Ashland transferred $378 million of the outstanding pension benefit obligation to Prudential in exchange for pension trust assets whose value approximated the liability value. The annuity purchase transaction did not generate a material settlement adjustment during 2016. Prudential has unconditionally and irrevocably guaranteed the full payment of benefits to plan participants associated with the annuity purchase and benefit payments will be in the same form that was in effect under the Plan. Prudential has also assumed all investment risk associated with the pension assets that were delivered as annuity contract premiums. Pension plan settlement program During 2015, Ashland informed approximately 20,000 former employees, who were included in the approximately 53,000 participants within the primary U.S. pension plans, that Ashland was offering these participants the option of receiving a lump sum payment on their vested retirement benefit or a reduced annuity now, in lieu of receiving monthly annuity payments deferred until retirement eligibility or when the participant may choose to initiate payment. During August 2015, approximately 12,000 participants elected to participate in the settlement program which resulted in approximately $475 million in settlement payments made from the affected pension plans during September 2015. Settlement payments were funded with pension plan assets, which included the $500 million contribution made during the third quarter of fiscal 2015. Additionally, as a result of this settlement program, Ashland recognized a $3 million settlement gain during 2015, of which $1 million and $2 million was recognized in the cost of sales and selling, general and administrative expense captions, respectively, within the Statements of Consolidated Comprehensive Income. Pension plans divested As a result of the sale of the Water Technologies business on July 31, 2014, certain non-U.S. pension plans, with a net benefit obligation of $70 million were fully transferred. Other postretirement benefit plans Ashland and its subsidiaries sponsor health care and life insurance plans for eligible employees in the U.S. and Canada who retire or are disabled. Ashland’s retiree life insurance plans are noncontributory, while Ashland shares the costs of providing health care coverage with its retired employees through premiums, deductibles and coinsurance provisions. Ashland funds its share of the costs of the postretirement benefit plans as the benefits are paid. Employees hired after June 30, 2003, and participating in the Ashland plans, will have access to any retiree health care coverage that may be provided, but will have no Ashland company funds available to help pay for such coverage. Since January 1, 2004, Ashland’s legacy plans have limited their annual per capita costs to an amount equivalent to base year per capita costs, plus annual increases of up to 1.5% per year for costs incurred. As a result, health care cost trend rates have no significant effect on the amounts reported for the health care plans. Premiums for retiree health care coverage are equivalent to the excess of the estimated per capita costs over the amounts borne by Ashland. For certain other plans that have been acquired, the assumed postretirement health care plans include a limit on Ashland’s share of costs for recent and future retirees. The assumed pre-65 health care cost trend rate as of September 30, 2016 was 7.9% and continues to be reduced to 4.50% in 2037 and thereafter. The assumptions used to project the liability anticipate future cost-sharing changes to the written plans that are consistent with the increase in health care cost. Employees hired after December 31, 2002 will have access to any retiree health care coverage that may be provided, but will have no Ashland company funds available to help pay for such coverage. In May 2010, Ashland implemented changes for all plans, effective January 1, 2011, eliminating post-65 benefit coverage for those eligible participants retiring on or after January 1, 2016. In September 2011, Ashland adopted a plan amendment for the legacy Ashland plans to change the current post-65 Ashland Medical plan to Medicare Advantage plan. This change was effective January 1, 2012, at which time Ashland no longer applied for the Medicare Part D subsidy. In September 2012, Ashland further reduced the employer subsidy for the post-65 Ashland legacy Medicare Advantage Plan to account for the impact of certain changes to the prescription drug program adopted as part of the September 2011 plan amendment. During March 2016, Ashland announced that it will eliminate post-65 and pre-65 retiree medical subsidies for active employees participating in Ashland sponsored plans. Additionally, Ashland announced that it will eliminate retiree life insurance benefits to active employees. These changes to retiree medical and life benefits are effective January 1, 2017 and October 1, 2016, respectively. This amendment reduced the benefit obligations by $86 million, which will be amortized to income in future periods. Change in Applying Discount Rate to Measure Benefit Costs During 2016, Ashland changed the method used to estimate the service and interest cost components of net periodic benefit cost for pension and other postretirement benefits. This change compared to the previous method resulted in a decrease in the service and interest cost components for pension and other postretirement benefit costs during the quarter. Historically, Ashland estimated these service and interest cost components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. Ashland has elected to utilize a full yield curve approach in the estimation of these components by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. Ashland has made this change to provide a more precise measurement of service and interest costs by improving the correlation between projected benefit cash flows to the corresponding spot yield curve rates. This change does not affect the measurement of Ashland’s total benefit obligations or annual net periodic benefit costs as the change in the service and interest costs will be offset in the actuarial gain or loss reported, which typically occurs during the fourth fiscal quarter. Ashland has accounted for this change as a change in accounting estimate that is inseparable from a change in accounting principle and accordingly has accounted for it prospectively. The impact of this discount rate change compared to the previous method decreased the estimated pension and other postretirement benefits service and interest cost by $33 million for the full year 2016. The impact on service cost is not significant due to the nature of Ashland’s largest U.S. pension plan, which is closed to new entrants and has curtailed other benefits. Of this annual decrease, $13 million was reported in cost of sales and $20 million was reported in selling, general, and administrative expense within the Statements of Consolidated Comprehensive Income in the Unallocated and other segment. Service and interest cost, as well as the other components of net periodic benefit costs, were subject to change for such reasons as an event requiring a remeasurement. Ashland’s total projected benefit obligations was not impacted by these reductions in service and interest costs as the decrease was substantially offset within the actuarial gain or loss caption when the plans were remeasured during the fiscal year. Plan Amendments and Remeasurements During the year ended September 30, 2016, Ashland was required to remeasure a majority of its U.S. pension plans and certain postretirement benefit plans due to the previously discussed plan changes announced during March 2016. The net effect of these plan changes resulted in a curtailment of benefits requiring a remeasurement of the benefit obligation and plan assets. Ashland recognized a loss of $23 million within the Statements of Consolidated Comprehensive Income during 2016 as a result of the plan remeasurements. The following details the components of the remeasurement impact: •As a result of the remeasurement of the affected U.S. pension plans, Ashland recognized a curtailment gain of $65 million and actuarial loss of $123 million during 2016. •As a result of the remeasurement of other postretirement benefit plans, Ashland recognized a curtailment gain of $39 million and actuarial loss of $7 million during 2016. •Ashland was also required to remeasure a non-U.S. pension plan and as a result recognized a curtailment gain of $6 million and actuarial loss of $3 million during 2016. During the year ended September 30, 2015, Ashland was required to remeasure a non-U.S. pension plan due to the exit of Water Technologies’ employees from the plan. As a result of the remeasurement, Ashland recognized a curtailment gain of $7 million and actuarial loss of $11 million during 2015. Of these amounts, all of the curtailment gain and $2 million of the actuarial loss were attributable to the Water Technologies business and therefore included in the discontinued operations caption of the Statements of Consolidated Comprehensive Income during 2015. During the year ended September 30, 2014, Ashland settled two non-U.S. pension plans, which required the plans to be remeasured. These remeasurements resulted in Ashland recognizing a settlement loss of $38 million and actuarial loss of $17 million. Of these amounts, $6 million of the settlement loss and $3 million of the actuarial loss were attributable to the Water Technologies business and therefore included in the discontinued operations caption of the Statements of Consolidated Comprehensive Income during 2014. Due to the global restructuring plan initiated in January 2014, Ashland was required to remeasure certain pension and other postretirement plan obligations, which included updating assumptions related to these plans such as the discount rate, asset values and demographic data that were last updated at Ashland’s fiscal year end. As a result of the remeasurements, Ashland recognized a curtailment loss of $6 million and actuarial loss of $83 million during the year ended September 30, 2014. Of these amounts, $14 million of the actuarial loss was attributable to the Water Technologies business and included in the discontinued operations caption of the Statements of Consolidated Comprehensive Income during 2014. As a result of the completion of the sale of Water Technologies on July 31, 2014, Ashland was required to remeasure certain pension and other postretirement plan obligations. As a result of the remeasurements, Ashland recognized a curtailment gain of $31 million and actuarial loss of $140 million during the year ended September 30, 2014. Of these amounts, all of the curtailment gain and $27 million of the actuarial loss were attributable to the Water Technologies business and included in the discontinued operations caption of the Statements of Consolidated Comprehensive Income during 2014. Components of net periodic benefit costs (income) For segment reporting purposes, service cost for continuing operations is proportionately allocated to each reportable segment, excluding the Unallocated and other segment, while all other costs for continuing operations are recorded within the Unallocated and other segment. During the year ended September 30, 2014, income of $7 million, representing a portion of the other components of pension and other postretirement benefit costs (i.e., interest cost, expected return on assets, and amortization of prior service credit) related to Water Technologies, was reclassified to discontinued operations in the Statements of Consolidated Comprehensive Income. The following table summarizes the components of pension and other postretirement benefit costs for both continuing and discontinued operations and the assumptions used to determine net periodic benefit costs (income) for the plans.
The following table shows other changes in prior service credit recognized in accumulated other comprehensive income.
The following table shows the amount of prior service credit in accumulated other comprehensive income at September 30, 2016 that is expected to be recognized as a component of net periodic benefit cost (income) during the next fiscal year.
At September 30, 2016 and 2015, the amounts recognized in accumulated other comprehensive income are shown in the following table.
Obligations and funded status Actuarial valuations are performed for the pension and other postretirement benefit plans to determine Ashland’s obligation for each plan. In accordance with U.S. GAAP, Ashland recognizes the unfunded status of the plans as a liability in the Consolidated Balance Sheets. Summaries of the change in benefit obligations, plan assets, funded status of the plans, amounts recognized in the balance sheet, and assumptions used to determine the benefit obligations for 2016 and 2015 are as follows.
The accumulated benefit obligation for all pension plans was $3,569 million at September 30, 2016 and $3,750 million at September 30, 2015. Information for pension plans with an accumulated benefit obligation in excess of plan assets follows:
Plan assets The expected long-term rate of return on U.S. pension plan assets was 7.10% and 7.65% for 2016 and 2015, respectively. The basis for determining the expected long-term rate of return is a combination of future return assumptions for various asset classes in Ashland’s investment portfolio, historical analysis of previous returns, market indices and a projection of inflation. The following table summarizes the various investment categories that the pension plan assets are invested in and the applicable fair value hierarchy that the financial instruments are classified within these investment categories as of September 30, 2016. For additional information and a detailed description of each level within the fair value hierarchy, see Note G.
The following table summarizes the various investment categories that the pension plan assets are invested in and the applicable fair value hierarchy that the financial instruments are classified within these investment categories as of September 30, 2015.
Ashland’s pension plan holds a variety of investments designed to diversify risk. Investments classified as a Level 1 fair value measure principally represent marketable securities priced in active markets. Cash and cash equivalents and public equity and debt securities are well diversified and invested in U.S. and international small-to-large companies across various asset managers and styles. Investments classified as a Level 2 fair value measure principally represents fixed-income securities in U.S. treasuries and agencies and other investment grade corporate bonds and debt obligations. Ashland’s pension plans also hold Level 3 investments primarily within hedge funds and private equity funds with hedge funds accounting for nearly all of the Level 3 investments. Ashland’s investments in these funds are primarily valued using the net asset value per share of underlying investments as determined by the respective individual fund administrators on a daily, weekly or monthly basis, depending on the fund. Such valuations are reviewed by the portfolio managers who determine the estimated value of the collective funds based on these inputs. The following table provides a reconciliation of the beginning and ending balances for these Level 3 assets.
Investments and Strategy In developing an investment strategy for its defined benefit plans, Ashland has considered the following factors: the nature of the plans’ liabilities, the allocation of liabilities between active, deferred and retired members, the funded status of the plans, the applicable investment horizon, the respective size of the plans and historical and expected capital market returns. Ashland’s U.S. pension plan assets are managed by outside investment managers, which are monitored against investment return benchmarks and Ashland’s established investment strategy. Investment managers are selected based on an analysis of, among other things, their investment process, historical investment results, frequency of management turnover, cost structure and assets under management. Assets are periodically reallocated between investment managers to maintain an appropriate asset mix and diversification of investments and to optimize returns. The current target asset allocation for the U.S. plan is 51% fixed securities and 49% equity securities. Fixed income securities primarily include long duration high grade corporate debt obligations. Risk assets include both traditional equity as well as a mix of non-traditional assets such as hedge funds and private equity. Investment managers may employ a limited use of derivatives to gain efficient exposure to markets. Ashland’s investment strategy and management practices relative to plan assets of non-U.S. plans generally are consistent with those for U.S. plans, except in those countries where investment of plan assets is dictated by applicable regulations. The weighted-average asset allocations for Ashland’s U.S. and non-U.S. plans at September 30, 2016 and 2015 by asset category follow.
Cash flows U.S. pension legislation and future funding requirements Ashland’s U.S. qualified pension plans funding requirements through fiscal 2017 are calculated in accordance with the regulations set forth in the Moving Ahead for Progress in the 21st Century Act (MAP-21), which provides temporary relief for employers who sponsor defined benefit pension plans related to funding contributions under the Employee Retirement Income Security Act of 1974. Specifically, MAP-21 allows for the use of a 25-year average interest rate within an upper and lower range for purposes of determining minimum funding obligations instead of an average interest rate for the two most recent years, as was previously required. During fiscal 2016 and 2015, Ashland contributed $23 million and $596 million, respectively, to its U.S. pension plans and $12 million and $14 million, respectively, to its non-U.S. pension plans. The 2015 contributions included $500 million to the U.S. pension plans impacted by the pension plan settlement program discussed previously. Ashland expects to contribute approximately $15 million to its non-qualified U.S. pension plans and $10 million to its non-U.S. pension plans during 2017. The following benefit payments, which reflect future service expectations, are projected to be paid in each of the next five years and in aggregate for five years thereafter.
Other plans Ashland sponsors savings plans to assist eligible employees in providing for retirement or other future needs. Under such plans, company contributions amounted to $35 million in 2016, $38 million in 2015 and $31 million in 2014. Ashland also sponsors various other benefit plans, some of which are required by different countries. The total noncurrent liabilities associated with these plans were $16 million as of September 30, 2016 and 2015. |

| 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 Hamilton, Rabinovitz & Associates, Inc. (HR&A). The methodology used by HR&A 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, HR&A 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. 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, a former subsidiary. 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 HR&A. During the most recent update completed during 2016, it was determined that the liability for Ashland asbestos-related claims should be increased by $37 million. Total reserves for asbestos claims were $415 million at September 30, 2016 compared to $409 million at September 30, 2015. 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. Substantially all of the estimated receivables from insurance companies are expected to be due from domestic insurers, all of which are solvent. In October 2012, Ashland and Hercules initiated various arbitration proceedings against Underwriters at Lloyd’s, certain London companies and/or Chartis (AIG) member companies seeking to enforce these insurers’ contractual obligations to provide indemnity for asbestos liabilities and defense costs under existing coverage-in-place agreements. In addition, Ashland and Hercules initiated a lawsuit in Kentucky state court against certain Berkshire Hathaway entities (National Indemnity Company and Resolute Management, Inc.) on grounds that these Berkshire Hathaway entities had wrongfully interfered with Underwriters’ and Chartis’ performance of their respective contractual obligations to provide asbestos coverage by directing the insurers to reduce and delay certain claim payments. On January 13, 2015, Ashland and Hercules entered into a comprehensive settlement agreement related to certain insurance coverage for asbestos bodily injury claims with Underwriters at Lloyd’s, certain London companies and Chartis (AIG) member companies, along with National Indemnity Company and Resolute Management, Inc., under which Ashland and Hercules received a total of $398 million. In exchange, all claims were released against these entities for past, present and future coverage obligations arising out of the asbestos coverage-in-place agreements that were the subject of the pending arbitration proceedings. In addition, as part of this settlement, Ashland and Hercules released all claims against National Indemnity Company and Resolute Management, Inc. in the Kentucky state court action. As a result, the arbitration proceedings and the Kentucky state court action have been terminated. As a result of this settlement, Ashland recorded an after-tax gain of $120 million within the discontinued operations caption of the Statements of Consolidated Comprehensive Income during 2015. The Ashland insurance receivable balance was also reduced as a result of this settlement by $227 million within the Consolidated Balance Sheets. In addition, during 2015, Ashland placed $335 million of the settlement funds received into a renewable annual trust restricted for the purpose of paying for ongoing and future litigation defense and claim settlement costs incurred in conjunction with asbestos claims. At September 30, 2016, Ashland’s receivable for recoveries of litigation defense and claim settlement costs from insurers amounted to $151 million (excluding the Hercules receivable for asbestos claims), of which $6 million relates to costs previously paid. Receivables from insurers amounted to $150 million at September 30, 2015. During 2016, 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 $16 million increase in the receivable for probable insurance recoveries. During 2016, Ashland entered into settlement agreements totaling $4 million with certain insurers, which resulted in a reduction of the Ashland insurance receivable within the Consolidated Balance Sheets by the same amount. Ashland placed $4 million of the settlement funds into the renewable annual trust. 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 HR&A. As a result of the most recent annual update of this estimate, completed during 2016, it was determined that the liability for Hercules asbestos-related claims should be increased by $25 million. Total reserves for asbestos claims were $321 million at September 30, 2016 compared to $311 million at September 30, 2015. 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 September 30, 2016 and 2015, the receivables from insurers amounted to $63 million and $56 million, respectively. During 2016, 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 $7 million increase in the receivable for probable insurance recoveries. As a result of the January 2015 asbestos insurance settlement previously described, Hercules resolved all disputes with Chartis (AIG) member companies under their existing coverage-in-place agreement for past, present and future Hercules asbestos claims. As a result, during 2015, a $22 million reduction in the insurance receivable balance within the Consolidated Balance Sheets was recorded. 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. In light of 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 $670 million for the Ashland asbestos-related litigation (current reserve of $415 million) and approximately $490 million for the Hercules asbestos-related litigation (current reserve of $321 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 September 30, 2016, such locations included 81 waste treatment or disposal sites where Ashland has been identified as a potentially responsible party under Superfund or similar state laws, 130 current and former operating facilities (including certain operating facilities conveyed as part of the MAP Transaction) and about 1,225 service station properties, of which 64 are being actively remediated. Ashland’s reserves for environmental remediation and related environmental litigation amounted to $177 million at September 30, 2016 compared to $186 million at September 30, 2015, of which $134 million at September 30, 2016 and $139 million at September 30, 2015 were classified in other noncurrent liabilities on the Consolidated Balance Sheets. The following table provides a reconciliation of the changes in the environmental remediation reserves during 2016 and 2015.
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 September 30, 2016 and 2015, Ashland’s recorded receivable for these probable insurance recoveries was $23 million, of which $15 million and $16 million, respectively, were classified in other noncurrent assets in the Consolidated Balance Sheets. Components of environmental remediation expense included within the selling, general and administrative expense caption of the Statements of Consolidated Comprehensive Income are presented in the following table for the years ended September 30, 2016, 2015 and 2014.
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 $380 million. No individual remediation location is significant, as the largest reserve for any site is less than 15% 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 September 30, 2016 and 2015. 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 September 30, 2016 and 2015. For additional information on legal proceedings and claims, see the Legal Proceedings section of Form 10-K (Part I, Item 3). |

| EQUITY ITEMS | Stock repurchase programs During 2015, Ashland’s Board of Directors approved a $1 billion share repurchase authorization that will expire on December 31, 2017 (the 2015 stock repurchase program). This authorization allows for common shares to be repurchased in open market transactions, privately negotiated transactions or pursuant to one or more accelerated stock repurchase programs or Rule 10b5-1 plans. During 2014, the Board of Directors of Ashland authorized a $1.35 billion common stock repurchase program (the 2014 stock repurchase program). Under the program, Ashland’s common shares were repurchased pursuant to accelerated stock repurchase agreements, a Rule 10b5-1 plan, and a prepaid variable share repurchase agreement. This repurchase program was completed during 2015. The 2014 stock repurchase program authorization replaced Ashland’s previous $600 million share repurchase authorization(the 2013 stock repurchase program), approved in May 2013, which had $450 million remaining when it was terminated. 2015 stock repurchase program agreement In November 2015, under the 2015 stock repurchase program, Ashland announced that it entered into an accelerated share repurchase agreement (2016 ASR Agreement) with Goldman, Sachs & Co. Under the 2016 ASR Agreement, Ashland paid an initial purchase price of $500 million and received an initial delivery of approximately 3.9 million shares of common stock during November 2015. In February 2016, Goldman, Sachs & Co. exercised their early termination option under the 2016 ASR Agreement and the pricing period was closed. The settlement price, which represents the weighted average price of Ashland’s common stock over the pricing period less a discount, was $99.01 per share. Based on this settlement price, the final number of shares repurchased by Ashland that were delivered by Goldman, Sachs & Co. under the 2016 ASR Agreement was 5.1 million shares. Ashland received the additional 1.2 million shares during 2016 to settle the difference between the initial share delivery and the total number of shares repurchased. After the 2016 ASR Agreement, $500 million of share repurchase authorization remains under the 2015 stock repurchase program. 2014 stock repurchase program agreements Accelerated stock repurchase agreements During 2014, Ashland announced that it had entered into accelerated share repurchase agreements (2014 ASR Agreements) with Deutsche Bank AG, London Branch (Deutsche Bank), and JPMorgan Chase Bank, N.A. (JPMorgan) to repurchase an aggregate of $750 million of Ashland’s common stock. Under the 2014 ASR Agreements, Ashland paid an initial purchase price of $750 million, split evenly between the financial institutions. As of September 30, 2014, Ashland received an initial delivery of approximately 5.9 million shares of common stock under the 2014 ASR Agreements. The 2014 ASR Agreements had a variable maturity, at the financial institutions option, with a maximum pricing period termination date of June 30, 2015. During 2015, the 2014 ASR Agreements terminated pursuant to their terms and the pricing period was closed. The settlement price, which represents the weighted average price of Ashland’s common stock over the pricing period less a discount, was $116.33 per share. Based on this settlement price, the final number of shares repurchased by Ashland that were delivered by the financial institutions under the 2014 ASR Agreements was 6.4 million shares. Ashland received the additional 0.5 million shares from the financial institutions during 2015 to settle the difference between the initial share delivery and the total number of shares repurchased. During 2015, Ashland announced and completed accelerated share repurchase agreements (2015 ASR Agreements) with Deutsche Bank and JPMorgan to repurchase an aggregate of $270 million of Ashland’s common stock. Under the 2015 ASR Agreements, Ashland paid an initial purchase price of $270 million, split evenly between the financial institutions and received an initial delivery of approximately 1.9 million shares of common stock. The 2015 ASR Agreements had a variable maturity, at the financial institutions option, with a maximum pricing period termination date of July 31, 2015. During 2015, Deutsche Bank and JPMorgan exercised their early termination option under the 2015 ASR Agreements and the pricing period was closed. The settlement price, which represents the weighted average price of Ashland’s common stock over the pricing period less a discount, was $125.22 per share. Based on this settlement price, the final number of shares repurchased by Ashland that were delivered by the financial institutions under the 2015 ASR Agreements was 2.2 million shares. Ashland received the additional 0.3 million shares from the financial institutions during 2015 to settle the difference between the initial share delivery and the total number of shares repurchased. Additional stock repurchase agreements Ashland entered into and completed a $125 million prepaid variable share repurchase agreement during 2014. The settlement price, which represents the weighted average price of Ashland’s common stock over the pricing period less a discount, was $105.22 per share. Ashland received 0.8 million shares and $45 million in cash for the unused portion of the $125 million prepayment, for a net cash outlay of $80 million. During 2014, Ashland announced that it had entered into an agreement with each of Deutsche Bank Securities Inc. and JPMorgan to repurchase an aggregate of $250 million of Ashland’s common stock. Under the terms of the agreement, the financial institutions purchased a pre-determined number of shares on various trading days dependent upon Ashland’s prevailing stock price on that date. During 2014, Ashland received 1.2 million shares of common stock for a total cost of $124 million. During 2015, Ashland completed these agreements, receiving an additional 1.2 million shares of common stock for a total cost of $127 million. The settlement price, which represents the average amount spent after commissions over the common shares repurchased throughout the program, was $104.51 per share. In total, Ashland paid $250 million and received 2.4 million shares of common stock under the agreements. Stockholder dividends In May 2015, the Board of Directors of Ashland announced a quarterly cash dividend increase to 39 cents per share to eligible shareholders of record. This amount was paid for quarterly dividends during each quarter of fiscal 2016 and the third and fourth quarters of fiscal 2015, and was an increase from the quarterly cash dividend of 34 cents per share paid during the first and second quarters of fiscal 2015 and each quarter of fiscal 2014. Shares reserved for issuance At September 30, 2016, 7.7 million common shares are reserved for issuance under stock incentive and deferred compensation plans. Accumulated other comprehensive income (loss) Components of other comprehensive income (loss) recorded in the Statements of Consolidated Comprehensive Income are presented in the following table, before tax and net of tax effects.
In accordance with U.S. GAAP, as disclosed in the table above, certain pension and other postretirement costs (income) are amortized from accumulated other comprehensive income and recognized in net income. The captions on the Statements of Consolidated Comprehensive Income impacted by the amortization of unrecognized prior service credits for pension and other postretirement plans are disclosed below. During 2016, the amortization of unrecognized prior service credits includes the curtailment impact of the pension and other postretirement plan remeasurements related to plan amendments of $40 million. See Note N for more information on curtailments, settlements and other costs.

| STOCK INCENTIVE PLANS | Ashland has stock incentive plans under which key employees or directors are granted stock appreciation rights (SARs), performance share 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 pretax stock-based awards (net of forfeitures), which is included within the selling, general and administrative expense caption of the Statements of Consolidated Comprehensive Income, and associated income tax benefits are as follows:
Stock Appreciation Rights (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 lapse ten years and one month after the date of grant. 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. The following table illustrates the weighted-average of key assumptions used within the Black-Scholes option-pricing model. The risk-free interest rate assumption was based on the U.S. Treasury yield curve in effect at the time of the grant for the expected term of the instrument. The dividend yield reflects the assumption that the current dividend payout will continue with no anticipated increases. The volatility assumption was calculated by utilizing an unbiased standard deviation of Ashland’s Common Stock closing price for the past five years. The expected life is based on historical data and is not necessarily indicative of exercise patterns that may occur.
A progression of activity and various other information relative to SARs and previously issued and vested stock options is presented in the following table.
The total intrinsic value of SARs exercised was $11 million in 2016, $35 million in 2015 and $50 million in 2014. The actual tax benefit realized from the exercised SARs was $2 million in 2016, $6 million in 2015 and $18 million in 2014. The total grant date fair value of SARs that vested during 2016, 2015 and 2014 was $9 million, $13 million and $21 million, respectively. As of September 30, 2016, 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. As of September 30, 2016, the aggregate intrinsic value of outstanding SARs was $49 million and exercisable SARs was $46 million. 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. During 2016, these awards were primarily granted as stock units that will convert to shares upon vesting, while the grants in prior years were generally made in nonvested shares. 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. A progression of activity and various other information relative to nonvested stock awards is presented in the following table.
The total fair value of nonvested stock awards that vested during 2016, 2015 and 2014 was $10 million, $5 million and $4 million, respectively. As of September 30, 2016, there was $11 million of total unrecognized compensation costs related to nonvested stock awards. That cost is expected to be recognized over a weighted-average period of 1.6 years. Cash-settled nonvested stock awards Certain nonvested stock awards are granted to employees and are settled in cash upon vesting. As of September 30, 2016, 94,600 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 $4 million and $1 million during 2016 and 2015, respectively. Performance shares Ashland sponsors a long-term incentive plan that awards performance shares/units to certain key employees that are tied to Ashland’s overall financial performance relative to the financial performance of selected industry peer groups and/or internal targets. Awards are granted annually, with each award covering a three-year vesting period. Each performance share/unit is convertible to one share of Ashland Common Stock. These plans are recorded as a component of stockholders’ equity in the Consolidated Balance Sheets. Performance measures used to determine the actual number of performance shares issuable upon vesting include an equal weighting of Ashland’s total shareholder return (TSR) performance and Ashland’s return on investment (ROI) performance as compared to the internal targets. TSR relative to peers is considered a market condition while ROI is considered a performance condition under applicable U.S. GAAP. Nonvested performance shares/units do not entitle employees to vote the shares or to receive any dividends thereon. The following table shows the performance shares/units granted for all plans that award Ashland Common Stock.
The fair value of the ROI portion of the performance share awards is equal to the fair market value of Ashland’s Common Stock on the date of the grant discounted for the dividends forgone during the vesting period of the three-year performance cycle. Compensation cost is recognized over the requisite service period if it is probable that the performance condition will be satisfied. The fair value of the TSR portion of the performance share awards is calculated using a Monte Carlo simulation valuation model using key assumptions included in the following table. Compensation cost is recognized over the requisite service period regardless of whether the market condition is satisfied.
The following table shows changes in nonvested performance shares/units for all plans that award Ashland Common Stock.
As of September 30, 2016, there was $8 million of total unrecognized compensation costs related to nonvested performance share awards. That cost is expected to be recognized over a weighted-average period of approximately 1.7 years. Other commitments Executive performance incentive and retention program During 2016, certain executives were granted 260 thousand performance-based restricted shares of Ashland in order to provide an incentive to remain employed in the period after the full separation. At September 30, 2016, total nonvested shares outstanding, assuming vesting at the 100% performance level, are 264 thousand shares, which includes the cumulative value of forfeitable dividends. The expense associated with these awards is contingent upon the completion of the full separation and therefore will not be recorded until the full and complete separation occurs. Based on the price of Ashland’s common stock on the grant date, the total estimated unrecognized compensation expense is $15 million assuming the performance mid-point target is met. At that time, the awards will be recognized ratable over the remaining vesting period. |

| 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 reviewed by the chief operating decision maker in assessing each reportable segment’s financial performance. Ashland performed an internal structural review and comprehensive assessment of its operations and reportable segments and concluded that its operating and reportable segments were Specialty Ingredients, Performance Materials and Valvoline. Ashland does not aggregate operating segments to arrive at these reportable segments. Reportable segment business descriptions Specialty Ingredients is a global leader in cellulose ethers, vinyl pyrrolidones and biofunctionals. It offers industry-leading products, technologies and resources for solving formulation and product-performance challenges. Specialty Ingredients uses 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 includes two divisions, Consumer Specialties and Industrial Specialties, that offer comprehensive and innovative solutions for today’s demanding consumer and industrial applications. Key customers include: pharmaceutical companies; makers of personal care products, food and beverages; manufacturers of paint, coatings and construction materials; packaging and converting; and oilfield service companies. During 2015, Ashland sold the industrial biocides assets within Specialty Ingredients. See Note C for information on the divestiture of these assets. Performance Materials is a global leader in unsaturated polyester resins and vinyl ester resins. The business unit has leading positions in gelcoats, maleic anhydride, butanediol, tetrahydrofuran, N-Methylpyrrolidone and other intermediates and solvents. Key customers include: manufacturers of residential and commercial building products; industrial product specifiers and manufacturers; wind blade and pipe manufacturers; automotive and truck OEM suppliers; boatbuilders; engineered plastics and electronic producers; and specialty chemical manufacturers. Results from the former Elastomers division were included in Performance Materials’ results of operations within the Statements of Consolidated Comprehensive Income until its December 1, 2014 sale. See Note C for information on the divestiture of the Elastomers division. Valvoline is a leading worldwide producer and distributor of premium-branded automotive, commercial and industrial lubricants, and automotive chemicals. In 2016, it ranked as the #2 quick-lube chain by number of stores and #3 passenger car motor oil in the DIY market by volume brand in the United States. The brand operates and franchises 1,068 Valvoline Instant Oil ChangeSM centers in the United States. It also markets ValvolineTM lubricants and automotive chemicals; MaxLifeTM lubricants created for higher-mileage engines; SynPowerTM synthetic motor oil; and ZerexTM antifreeze. Key customers include: retail auto parts stores and mass merchandisers who sell to consumers; installers, such as car dealers, repair shops and quick lubes; commercial fleets; and distributors. During 2016, Ashland completed the acquisition of Oil Can Henry’s resulting in the addition of 89 quick-lube stores. See Note B for information on the acquisition of Oil Can Henry’s. During 2015, Ashland sold its Valvoline car care product assets, including Car BriteTM and Eagle OneTM automotive appearance products, and sold its joint venture equity investment in Venezuela. See Note B for information on the divestiture of this investment and the car care product assets. During 2015, Ashland announced a plan to separate Valvoline into an independent, publicly traded company. On September 22, 2016, Ashland and Valvoline Inc. announced an IPO of Valvoline Inc.’s common stock at a price to the public of $22.00 per share and closed the IPO on September 28, 2016. As a result of the IPO, Ashland maintains an approximately 83% ownership interest in Valvoline Inc. as of September 30, 2016. See Note B for additional information. The financial information within this footnote is reflective of the manner in which Ashland manages the Valvoline reportable segment and the Valvoline reportable segment does not include any assets or liabilities transferred to Valvoline Inc. by Ashland in September 2016. Valvoline’s financial position and results of operations as reported as a segment of Ashland may be different than how they are reported on a stand-alone basis. Unallocated and other generally includes items such as components of pension and other postretirement benefit plan expenses (excluding service costs, which are allocated to the reportable segments), 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. International data Information about Ashland’s domestic and international operations follows. Ashland has no material operations in any individual international country and no single customer represented more than 10% of sales in 2016, 2015 or 2014.
Reportable segment results The following tables present various financial information for each reportable segment for the years ended September 30, 2016, 2015 and 2014 and as of September 30, 2016, 2015 and 2014. Results of Ashland’s reportable segments are presented based on its management structure and internal accounting practices. The structure and practices are 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 costs to its reportable segments except for certain significant company-wide restructuring activities, such as the restructuring plans described in Note F, 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 to Unallocated and other. 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. Revisions to Ashland’s methodologies that are deemed insignificant are applied on a prospective basis. Ashland determined that disclosing sales by specific product was impracticable due to the highly customized and extensive portfolio of products offered to customers and since no one product or a small group of products could be aggregated together to represent a majority of revenue within a reportable segment. As such, the following table provides a summary of 2016 sales by product category for each reportable segment:
The following table presents various financial information for each reportable segment. The operating results of divested divisions and assets during 2016, 2015 and 2014 that did not qualify for discontinued operations accounting treatment are included in the financial information until the date of sale.

| SUPPLEMENTAL GUARANTOR INFORMATION | The following tables present condensed consolidating financial information for (a) Ashland Global Holdings Inc. (for purposes of this discussion and table, Parent Guarantor); (b) Ashland LLC (formerly Ashland Inc.), the issuer of the 3.875% notes due 2018, 4.750% notes due 2022 and 6.875% notes due 2043 (collectively referred to as the Senior Notes) (the Issuer); and (c) all other non-guarantor subsidiaries of the Parent Guarantor on a combined basis, none of which guaranteed the Senior Notes (the Other Non-Guarantor Subsidiaries). Ashland Global Holdings Inc. was incorporated on May 6, 2016 as a direct wholly owned subsidiary of Ashland Inc. (now Ashland LLC) to reincorporate in Delaware and to help facilitate the separation of the Valvoline business from the specialty chemical businesses. As a result of the Reorganization, Ashland Global Holdings Inc. replaced Ashland Inc. as the publicly held corporation, and Ashland Inc. was converted to a Kentucky limited liability company and is now an indirect, wholly owned subsidiary of Ashland Global Holdings Inc. Ashland Global Holdings Inc. fully and unconditionally guaranteed the Senior Notes and has no significant independent assets or operations. For periods prior to September 30, 2016, the parent entity was Ashland LLC (formerly Ashland Inc.). Ashland presents all investments in subsidiaries in the supplemental guarantor information using the equity method of accounting. Therefore, the net income (loss) of the subsidiaries accounted for using the equity method is in their parents’ investment accounts. For each financial statement period presented within the following tables, Ashland Global Holdings Inc.’s activity reflects the accounting for investments in subsidiaries under the equity method reflective of the 2016 Reorganization and resulting presentation. The elimination entries within the tables primarily eliminate investments in subsidiaries and inter-company balances and transactions. The total net effect of the settlement of these inter-company transactions is reflected in the Condensed Statements of Cash Flows as a financing activity.

| Accounting Policies [Abstract] | |
| Consolidation, policy | Principles of consolidation and basis of presentation On September 20, 2016, Ashland was reincorporated under the laws of the State of Delaware through a tax-free reorganization under a new holding company structure (the Reorganization). As a result of the Reorganization, Ashland Global Holdings Inc. replaced Ashland Inc. as the publicly held corporation and, through its subsidiaries, now conducts all of the operations that historically were conducted by Ashland Inc. Pursuant to the terms of the Reorganization, each outstanding share of Ashland common stock was automatically converted into one share of Ashland Global Holdings Inc. common stock. Following consummation of the Reorganization, (i) Ashland Inc. was converted into Ashland LLC, an indirect, wholly owned subsidiary of Ashland Global Holdings Inc., and (ii) Ashland Global Holdings Inc., as the new holding company, will, through its subsidiaries, conduct all of the operations conducted by Ashland Inc. immediately prior to the Reorganization. The Consolidated Financial Statements include the accounts of Ashland Global Holdings Inc. and its majority owned subsidiaries and, when applicable, entities for which Ashland has a controlling financial interest or is the primary beneficiary (Ashland). For entities for which Ashland has a controlling financial interest but owns less than 100%, the outside stockholders’ interests are shown as noncontrolling interests. Investments in joint ventures and 20% to 50% owned affiliates where Ashland has the ability to exert significant influence are accounted for under the equity method. The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and U.S. Securities and Exchange Commission regulations. All material intercompany transactions and balances have been eliminated. Additionally, certain prior period data has been reclassified in the Consolidated Financial Statements and accompanying notes to conform to the current period presentation, which includes the adoption of of new accounting guidance during the current year related to the classification as noncurrent of all deferred tax assets and liabilities in the Consolidated Balance Sheet. Ashland is composed of three reportable segments: Ashland Specialty Ingredients (Specialty Ingredients), Ashland Performance Materials (Performance Materials) and Valvoline. As of September 30, 2016, Ashland maintains an approximately 83% controlling interest in Valvoline Inc., which holds the Valvoline reportable segment. See Note B for additional information. The term Valvoline as used herein, depending on context, refers to either Valvoline Inc. or Valvoline as a reportable segment of Ashland. On July 31, 2014, Ashland completed the sale of the assets and liabilities of Ashland Water Technologies (Water Technologies). As a result of the sale, all prior period operating results and cash flows related to Water Technologies have been reflected as discontinued operations in the Statements of Consolidated Comprehensive Income and Statements of Consolidated Cash Flows. During 2015, Ashland sold certain assets in its portfolio of businesses which were not reflected as discontinued operations. See Notes C and R for additional information on these activities as well as Ashland’s current reportable segment results. |
| Use of estimates, risks and uncertainties | Use of estimates, risks and uncertainties The preparation of Ashland’s 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), employee benefit obligations, 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. |
| Cash and cash equivalents | Cash and cash equivalents Cash and cash equivalents include cash on hand and highly liquid investments maturing within three months after purchase. |
| Allowance for doubtful accounts | Allowance for doubtful accounts Ashland records an allowance for doubtful accounts as a best estimate of the amount of probable credit losses for accounts receivable. Each month, Ashland reviews this allowance and considers factors such as customer credit, past transaction history with the customer and changes in customer payment terms when determining whether the collection of a receivable is reasonably assured. Past due balances over 90 days and over a specified amount are reviewed individually for collectibility. The allowance for doubtful accounts is adjusted when it becomes probable a receivable will not be recovered. |
| Inventories | Inventories Inventories are carried at the lower of cost or market. Inventories are primarily stated at cost using the weighted-average cost method. In addition, certain chemicals and lubricants with a replacement cost of $162 million at September 30, 2016 and $170 million at September 30, 2015 are valued at cost using the last-in, first-out (LIFO) method. |
| Property, Plant and Equipment | Property, plant and equipment The cost of property, plant and equipment is depreciated by the straight-line method over the estimated useful lives of the assets. Buildings are depreciated principally over 25 to 35 years and machinery and equipment principally over 2 to 25 years. Such costs are periodically reviewed for recoverability when impairment indicators are present. Such indicators include, among other factors, operating losses, unused capacity, market value declines and technological obsolescence. Recorded values of asset groups of property, plant and equipment that are not expected to be recovered through undiscounted future net cash flows are written down to current fair value, which generally is determined from estimated discounted future net cash flows (assets held for use) or net realizable value (assets held for sale). |
| Goodwill and other intangibles | Goodwill and other intangibles Ashland tests goodwill and other indefinite-lived intangible assets for impairment annually as of July 1 and when events and circumstances indicate an impairment may have occurred. Ashland reviews goodwill for impairment based on its identified reporting units, which are defined as operating segments or groupings of businesses one level below the operating segment level. Ashland tests goodwill for impairment by comparing the carrying value to the estimated fair value of its reporting units, determined using a combination of discounted cash flow models and valuations based on earnings multiples for guideline public companies in each reporting unit’s industry peer group, when externally quoted market prices are not readily available. If this comparison indicates that a reporting unit’s estimated fair value is less than its carrying value, a second step is required. If applicable, the second step requires the fair value of the reporting unit to be allocated to the estimated fair value of the reporting unit’s net assets, with any fair value in excess of amounts allocated to such net assets representing the implied fair value of goodwill for that reporting unit. The implied goodwill balance is compared to the actual carrying value of goodwill for the reporting unit to determine the goodwill impairment amount. Ashland tests its indefinite-lived intangible assets, principally trademarks and trade names, using a “relief-from-royalty” valuation method compared to the carrying value. Significant assumptions inherent in the valuation methodologies for goodwill and other intangibles are employed and include, but are not limited to, such estimates as future projected business results, growth rates, the weighted-average cost of capital for a market participant, and royalty and discount rates. If the carrying value of an individual indefinite-lived intangible asset exceeds its fair value, such individual indefinite-lived intangible asset is written down by an amount equal to such excess. Finite-lived intangible assets principally consist of certain trademarks and trade names, intellectual property, and customer lists. These intangible assets 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 20 years and customer relationships over 3 to 24 years. Ashland reviews finite-lived intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Ashland monitors these changes and events on at least a quarterly basis. For further information on goodwill and other intangible assets, see Note I. |
| Derivative instruments | Derivative instruments Ashland regularly uses derivative instruments to manage its exposure to fluctuations in foreign currencies and certain commodities. All derivative instruments are recognized as either assets or liabilities on the balance sheet and are measured at fair value. Changes in the fair value of all derivatives are recognized immediately in income unless the derivative qualifies as a hedge of future cash flows or a hedge of a net investment in a foreign operation. Gains and losses related to a hedge are either recognized in income immediately to offset the gain or loss on the hedged item, or deferred and recorded in the stockholders’ equity section of the Consolidated Balance Sheets as a component of accumulated other comprehensive income and subsequently recognized in the Statements of Consolidated Comprehensive Income when the hedged item affects net income. The ineffective portion of the change in fair value of a hedge is recognized in income immediately. For additional information on derivative instruments, see Note G. |
| Restricted investments | Restricted investments On January 13, 2015, Ashland and Hercules LLC (formerly Hercules Incorporated), an indirect wholly-owned subsidiary of Ashland that was acquired in 2009, entered into a comprehensive settlement agreement related to certain insurance coverage for asbestos bodily injury claims with Underwriters at Lloyd’s, certain London companies and Chartis (AIG) member companies, along with National Indemnity Company and Resolute Management, Inc., under which Ashland and Hercules received a total of $398 million (the January 2015 asbestos insurance settlement). During 2015, Ashland placed $335 million of the settlement funds into a renewable annual trust restricted for the purpose of paying ongoing and future litigation defense and claim settlement costs incurred in conjunction with asbestos claims. These funds are presented primarily as noncurrent assets, with $30 million classified within other current assets in the Consolidated Balance Sheets as of September 30, 2016 and 2015. As of September 30, 2016, the funds within the trust were primarily invested in equity and corporate bond investments with a portion maintained in demand deposits. The funds within the trust are classified as available-for-sale securities. Available-for-sale securities are reported at fair value with unrealized gains and losses, net of related deferred income taxes, included in the stockholders’ equity section of the Consolidated Balance Sheets as a component of accumulated other comprehensive income. Interest income and realized gains and losses on the available-for-sale securities are reported in the net interest and other financing expense caption in the Statements of Consolidated Comprehensive Income. See Notes G and O for additional information regarding fair value of these investments within the trust and the January 2015 asbestos insurance settlement. |
| Revenue recognition | Revenue recognition Sales generally are recognized when persuasive evidence of an arrangement exists, products are received or services are provided to customers, the sales price is fixed or determinable and collectibility is reasonably assured. Certain shipping and handling costs paid by the customer are recorded in sales, while those costs paid by Ashland are recorded in cost of sales. |
| Expense recognition | Expense recognition Cost of sales include material and production costs, as well as the costs of inbound and outbound freight, purchasing and receiving, inspection, warehousing, internal transfers and all other distribution network costs. Selling, general and administrative expense includes sales and marketing costs, advertising, customer support, environmental remediation, corporate and divisional administrative and other costs. Advertising costs ($64 million in 2016, $62 million in 2015 and $63 million in 2014) and research and development costs ($100 million in 2016, $110 million in 2015 and $114 million in 2014) are expensed as incurred. |
| Income taxes | Income taxes Ashland is subject to income taxes in the United States and numerous foreign jurisdictions. Significant judgment in the forecasting of taxable income using historical and projected future operating results is required in determining Ashland’s provision for income taxes and the related assets and liabilities. The provision for income taxes includes income taxes paid, currently payable or receivable, and deferred taxes. Deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities, and are measured using enacted tax rates and laws that are expected to be in effect when the differences reverse. Deferred tax assets are also recognized for the estimated future effects of tax loss carryforwards. The effect on deferred taxes of changes in tax rates is recognized in the period in which the enactment date occurs. Valuation allowances are established when necessary on a jurisdictional basis to reduce deferred tax assets to the amounts expected to be realized. In the event that the actual outcome of future tax consequences differs from Ashland’s estimates and assumptions due to changes or future events such as tax legislation, geographic mix of earnings, completion of tax audits or earnings repatriation plans, the resulting change to the provision for income taxes could have a material effect on the Statements of Consolidated Comprehensive Income and Consolidated Balance Sheets. For additional information on income taxes, see Note M. |
| Asbestos-related litigation | Asbestos-related litigation Ashland is subject to liabilities from claims alleging personal injury caused by exposure to asbestos. Such claims result from indemnification obligations undertaken in 1990 in connection with the sale of Riley Stoker Corporation (Riley) and the acquisition of Hercules Incorporated (Hercules) in November 2008. Although Riley, a former subsidiary, was neither a producer nor a manufacturer of asbestos, its industrial boilers contained some asbestos-containing components provided by other companies. Hercules, an indirect wholly-owned subsidiary of Ashland, 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 sold by one of Hercules’ former subsidiaries to a limited industrial market. Ashland retained Hamilton, Rabinovitz & Associates, Inc. (HR&A) to assist in developing and annually updating independent reserve estimates for future asbestos claims and related costs given various assumptions. The methodology used by HR&A to project future asbestos costs is based largely on Ashland’s recent experience, including claim-filing and settlement rates, disease mix, enacted legislation, open claims, and litigation defense. Ashland’s claim experience is compared to the results of previously conducted 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, HR&A 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. 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. For additional information on asbestos-related litigation, see Note O. 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 Hamilton, Rabinovitz & Associates, Inc. (HR&A). The methodology used by HR&A 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, HR&A 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. |
| Environmental remediation | Environmental remediation Accruals for environmental remediation are recognized when it is probable a liability has been incurred and the amount of that liability can be reasonably estimated. Such costs are charged to expense if they relate to the remediation of conditions caused by past operations or are not expected to mitigate or prevent contamination from future operations. Liabilities are recorded at estimated cost values based on experience, assessments and current technology, without regard to any third-party recoveries and are regularly adjusted as environmental assessments and remediation efforts continue. For additional information on environmental remediation, see Note O. 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. |
| Pension and other postretirement benefits | Pension and other postretirement benefits The funded status of Ashland’s pension and other postretirement benefit plans is recognized in the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the benefit obligation at September 30, the measurement date. For defined benefit pension plans, the benefit obligation is the projected benefit obligation (PBO) and for the other postretirement benefit plans, the benefit obligation is the accumulated postretirement benefit obligation (APBO). The PBO represents the actuarial present value of benefits expected to be paid upon retirement based on estimated future compensation levels. The APBO represents the actuarial present value of postretirement benefits attributed to employee services already rendered. The measurement of the benefit obligation is based on Ashland’s estimates and actuarial valuations. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age and years of service, as well as certain key assumptions that require significant judgment, including, but not limited to, estimates of discount rates, expected return on plan assets, rate of compensation increases, interest rates and mortality rates. The fair value of plan assets represents the current market value of assets held by an irrevocable trust fund for the sole benefit of participants. For additional information regarding plan assumptions and the current financial position of the pension and other postretirement plans, see Note N. Ashland recognizes the change in the fair value of plan assets and net actuarial gains and losses annually in the fourth quarter of each fiscal year and whenever a plan is determined to qualify for a remeasurement. The remaining components of pension and other postretirement benefits expense are recorded ratably on a quarterly basis. Pension and other postretirement benefits adjustments charged directly to cost of sales that are applicable to inactive participants are excluded from inventoriable costs. 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 to Unallocated and other. |
| Foreign currency translation | Foreign currency translation Operations outside the United States are measured primarily using the local currency as the functional currency. Upon consolidation, the results of operations of the subsidiaries and affiliates whose functional currency is other than the U.S. dollar are translated into U.S. dollars at the average exchange rates for the year while assets and liabilities are translated at year-end exchange rates. Adjustments to translate assets and liabilities into U.S. dollars are recorded in the stockholders’ equity section of the Consolidated Balance Sheets as a component of accumulated other comprehensive income and are included in net earnings only upon sale or substantial liquidation of the underlying foreign subsidiary or affiliated company. |
| Stock incentive plans | Stock incentive plans Ashland recognizes compensation expense for stock incentive plans awarded to key employees and directors, primarily in the form of stock appreciation rights (SARs), restricted stock and restricted stock units, performance shares and other non-vested stock awards, that are generally based upon the grant-date fair value over the appropriate vesting period. Ashland utilizes several industry accepted valuation models to determine the fair value. For further information concerning stock incentive plans, see Note Q. |
| Earnings per share | Earnings per share The following is the computation of basic and diluted earnings per share (EPS) from continuing operations attributable to Ashland. Earnings per share are reported under the treasury stock method. Stock options and SARs for each reported year whose grant price was greater than the market price of Ashland Common Stock at the end of each fiscal year 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 1.2 million for 2016, 0.7 million for 2015 and 0.6 million for 2014. |
| New accounting standards | New accounting pronouncements In August 2016, the FASB issued new accounting guidance on eight specific cash flow classification issues. The amendments in this guidance will become effective retrospectively for Ashland on October 1, 2018. Early adoption is permitted in any interim or annual period. Ashland is currently evaluating the impact this guidance may have on Ashland’s Consolidated Financial Statements. In March 2016, the FASB issued new accounting guidance for certain aspects of share-based payments to employees. This guidance requires all excess tax benefits and tax deficiencies related to share-based payments to be recognized as income tax expense in the income statement instead of additional paid in capital, and changes the classification of excess tax benefits from a financing activity to an operating activity within the statement of cash flows. This guidance also allows entities to make an accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. Lastly, this guidance increases the amount an employer can withhold to cover income taxes on awards and still qualify for equity classification and requires that cash paid by an employer when directly withholding shares for tax-withholding purposes be classified as a financing activity within the statement of cash flows. The guidance will become effective for Ashland on October 1, 2017. Ashland is currently evaluating the impact this guidance may have on Ashland’s Consolidated Financial Statements. 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 rights and obligations created by leases and to disclose key information about leasing arrangements. The presentation of the statements of comprehensive income and the statements of 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. Ashland is currently evaluating the impact this guidance may have on Ashland’s Consolidated Financial Statements. In January 2016, the FASB issued accounting guidance related to the recognition and measurement of financial assets and financial liabilities. The main objective of this guidance is enhancing the reporting model for financial instruments to provide users of financial statements with more decision-useful information. The amendments in this guidance address certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The guidance also eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet and clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The guidance will become effective for Ashland on October 1, 2018. Early application to financial statements of fiscal years or interim periods that have not yet been issued is permitted as of the beginning of the fiscal year of adoption. Ashland is currently evaluating the impact this guidance may have on Ashland’s Consolidated Financial Statements. In November 2015, the FASB issued accounting guidance requiring all deferred tax assets and liabilities to be classified as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. During 2016, Ashland adopted this new guidance and applied it retrospectively to the September 30, 2015 Consolidated Balance Sheet. The impact of this new guidance within this statement resulted in the reclassification of net current deferred taxes of $149 million with an increase to noncurrent deferred tax assets of $145 million and a decrease to noncurrent deferred tax liabilities of $4 million. In July 2015, the FASB issued accounting guidance to simplify the subsequent measurement of certain inventories by replacing the current lower of cost or market test with a lower of cost and net realizable value test. The guidance applies only to inventories for which cost is determined by methods other than last-in first-out and the retail inventory method. This guidance will become effective prospectively for Ashland on October 1, 2017, with early adoption permitted. Ashland is currently evaluating the new accounting standard and the impact this new guidance will have on Ashland’s Consolidated Financial Statements. In April 2015, the FASB issued accounting guidance to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement. Cloud computing arrangements represent the delivery of hosted services over the internet which includes software, platforms, infrastructure and other hosting arrangements. Under the guidance, customers that gain access to software in a cloud computing arrangement account for the software as internal-use software only if the arrangement includes a software license. This guidance will become effective prospectively for Ashland on October 1, 2016. In April 2015 and August 2015, the FASB issued accounting guidance to simplify the presentation of debt issuance costs by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs were not affected by this amendment. The adoption of the new guidance was on a retrospective basis. As a result of Ashland electing to early adopt this guidance during 2015, $28 million of debt issuance costs was presented as long-term debt as of September 30, 2015. 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 supersedes most current revenue recognition guidance, in an effort to converge the revenue recognition principles within U.S. GAAP. This new guidance also requires 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 have the option of using a full retrospective or a modified retrospective approach to adopt the new guidance. This guidance becomes effective for Ashland on October 1, 2018. Ashland is currently evaluating the new accounting standard and the available implementation options the standard allows as well as the impact this new guidance will have on Ashland’s Consolidated Financial Statements. In April 2014, the FASB issued accounting guidance amending the requirements for reporting discontinued operations (ASC 205 Presentation of Financial Statements and ASC 360 Property, Plant and Equipment). This guidance limits the requirement for discontinued operations treatment to the disposal of a component of an entity, or a group of components of an entity, that represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. Additionally, this new guidance no longer precludes discontinued operations presentation based on continuing involvement or cash flows following the disposal. Ashland adopted this guidance on October 1, 2014, which is applicable only to divestitures subsequent to the adoption date, and has evaluated each divestiture during the current and prior years under this new guidance. |

FAIR VALUE MEASUREMENTS (Policies) |
12 Months Ended |

| Fair Value Disclosures [Abstract] | |
| 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 through the use of fair value models, such as a discounted cash flow model or other standard pricing models that Ashland deems reasonable. |
| Marketable Securities, Trading Securities, Policy | Gains and losses related to deferred compensation investments are immediately recognized within the Statements of Consolidated Comprehensive Income. |
| Derivatives, Methods of Accounting, Derivatives Not Designated or Qualifying as Hedges, Policy | 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 of 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. |
| Derivatives, Methods of Accounting, Hedging Derivatives, Policy | Since 2014, Ashland has entered into foreign currency contracts in order to manage the foreign currency exposure of the net investment in certain foreign operations. These foreign currency contracts were primarily the result of certain proceeds from the sale of Water Technologies being received in non-U.S. denominated currencies during 2014 and ongoing management of the volatility in foreign currency exchange rates. Ashland designated the foreign currency contracts as hedges of net investments in its foreign subsidiaries. As a result, Ashland records these hedges at fair value using forward rates, with the effective portion of the gain or loss reported as a component of the cumulative translation adjustment within AOCI and subsequently recognized in the Statements of Consolidated Comprehensive Income when the hedged item affects net income. During 2016 and 2015, these foreign currency contracts were settled and Ashland entered into new foreign currency contracts designated as hedges of net investments in foreign subsidiaries. These settlements resulted in net gains recorded within the cumulative translation adjustment within AOCI of $4 million and $11 million during 2016 and 2015, respectively. As of September 30, 2016 and 2015, the total notional value of foreign currency contracts equaled $94 million and $175 million, respectively. The fair value of Ashland’s net investment hedge assets and liabilities are calculated using forward rates. Accordingly, these instruments are deemed to be Level 2 measurements within the fair value hierarchy. Counterparties to these net investment hedges are highly rated financial institutions which Ashland believes carry only a nominal risk of nonperformance. |

GOODWILL AND OTHER INTANGIBLES (Policies) |

| Goodwill and Intangible Assets Disclosure [Abstract] | |
| Goodwill and Intangible Assets, Goodwill, Policy | 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. Ashland determined that its reporting units for the allocation of goodwill include the Specialty Ingredients reportable segment, the Composites and Intermediates/Solvents reporting units within the Performance Materials reportable segment, and the Core North America, Quick Lubes and International reporting units within the Valvoline reportable segment. In the first step of the impairment model, Ashland compares the carrying value of each reporting unit to its respective estimated fair value. Ashland makes various estimates and assumptions in determining the estimated fair values of those units through the use of a combination of discounted cash flow models and valuations based on earnings multiples for guideline public companies in each reporting unit’s industry peer group. Discounted cash flow models are highly reliant on various assumptions. Significant assumptions Ashland utilized in these models for the current year included: projected business results and future industry direction, long-term growth factors and weighted-average cost of capital. Ashland uses assumptions that it deems to be reasonable estimates of likely future events and compares the total fair values of each reporting unit to Ashland’s market capitalization, and implied control premium, to determine if the fair values are reasonable compared to external market indicators. Subsequent changes in these key assumptions could affect the results of future goodwill impairment reviews. In conjunction with the July 1, 2016 annual assessment of goodwill, Ashland’s valuation techniques did not indicate any impairment for Specialty Ingredients, Composites, Core North America, Quick Lubes or International. Due to deterioration in the butanediol commodity market during 2016 in which the Intermediates/Solvents reporting unit operates (and the impact thereof on Ashland’s most recently completed three-year business plan), Ashland determined that the carrying value of the Intermediates/Solvents reporting unit exceeded its fair value at July 1, 2016, which resulted in the reporting unit failing the first step of the goodwill impairment test. Ashland then performed the second step of the goodwill impairment test, which involved, among other things, obtaining third-party appraisals of substantially all of Intermediates/Solvents tangible and intangible assets. Based on the results of its goodwill impairment testing as of July 1, 2016, Ashland recorded a pre-tax goodwill impairment charge of $171 million in the fourth quarter of 2016, which is in addition to a $10 million impairment related to Intermediates/Solvents property, plant and equipment, resulted in a total $181 million impairment charge for Intermediates/Solvents during 2016. A portion of the goodwill impairment was nondeductible. Ashland’s assessment of an impairment charge on any of these remaining assets currently classified as having indefinite lives, including goodwill, could result in additional impairment charges in future periods if any or all of the following events were to occur with respect to a particular reporting unit: a significant change in projected business results, a divestiture decision, increase in Ashland’s weighted-average cost of capital rates, decrease in growth rates or other assumptions, economic deterioration that is more severe or of a longer duration than anticipated, or another significant economic event. |
| Intangible Assets, Finite-Lived, Policy | Intangible assets principally consist of trademarks and trade names, intellectual property, customer relationships and in-process research and development (IPR&D). 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 20 years and customer relationships over 3 to 24 years. |
| Goodwill and Intangible Assets, Intangible Assets, Indefinite-Lived, Policy | As of September 30, 2015, IPR&D and certain intangible assets within trademarks and tradenames were classified as indefinite-lived and had a balance of $311 million. During 2016, Ashland started amortizing the remaining IPR&D assets since the technology was commercialized during this period. As a result, as of September 30, 2016, the indefinite-lived intangible assets consisted only of certain trademarks and trade names of $301 million. 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. In conjunction with the July 1, 2016 annual assessment of indefinite-lived intangible assets, Ashland’s models did not indicate any additional impairment for indefinite-lived intangible assets. Intangible assets were comprised of the following as of September 30, 2016 and 2015. |

| Commitments and Contingencies Disclosure [Abstract] | |
| Commitments and Contingencies, Policy [Policy Text Block] | Asbestos-related litigation Ashland is subject to liabilities from claims alleging personal injury caused by exposure to asbestos. Such claims result from indemnification obligations undertaken in 1990 in connection with the sale of Riley Stoker Corporation (Riley) and the acquisition of Hercules Incorporated (Hercules) in November 2008. Although Riley, a former subsidiary, was neither a producer nor a manufacturer of asbestos, its industrial boilers contained some asbestos-containing components provided by other companies. Hercules, an indirect wholly-owned subsidiary of Ashland, 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 sold by one of Hercules’ former subsidiaries to a limited industrial market. Ashland retained Hamilton, Rabinovitz & Associates, Inc. (HR&A) to assist in developing and annually updating independent reserve estimates for future asbestos claims and related costs given various assumptions. The methodology used by HR&A to project future asbestos costs is based largely on Ashland’s recent experience, including claim-filing and settlement rates, disease mix, enacted legislation, open claims, and litigation defense. Ashland’s claim experience is compared to the results of previously conducted 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, HR&A 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. 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. For additional information on asbestos-related litigation, see Note O. 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 Hamilton, Rabinovitz & Associates, Inc. (HR&A). The methodology used by HR&A 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, HR&A 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. |
| Environmental Costs, Policy [Policy Text Block] | Environmental remediation Accruals for environmental remediation are recognized when it is probable a liability has been incurred and the amount of that liability can be reasonably estimated. Such costs are charged to expense if they relate to the remediation of conditions caused by past operations or are not expected to mitigate or prevent contamination from future operations. Liabilities are recorded at estimated cost values based on experience, assessments and current technology, without regard to any third-party recoveries and are regularly adjusted as environmental assessments and remediation efforts continue. For additional information on environmental remediation, see Note O. 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. |

| Weighted-average of key assumptions used in pricing model | The following table illustrates the weighted-average of key assumptions used within the Black-Scholes option-pricing model.

The dividend yield reflects the assumption that the current dividend payout will continue with no anticipated increases. The volatility assumption was calculated by utilizing an unbiased standard deviation of Ashland’s Common Stock closing price for the past five years. The expected life is based on historical data and is not necessarily indicative of exercise patterns that may occur.
