Organization, Consolidation and Presentation of Financial Statements [Abstract]
Condensed Consolidated Financial Statements	Condensed Consolidated Financial Statements We prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the U.S. Securities and Exchange Commission for interim financial information. In accordance with those rules and regulations, we condensed or omitted certain information and disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP). We suggest that you read these condensed financial statements together with the financial statements and footnotes included in our annual report on Form 10-K for the fiscal year ended April 30, 2017 (2017 Form 10-K). We prepared the accompanying financial statements on a basis that is substantially consistent with the accounting principles applied in our 2017 Form 10-K. In our opinion, the accompanying financial statements include all adjustments, consisting only of normal recurring adjustments (unless otherwise indicated), necessary for a fair statement of our financial results for the periods covered by this report. The BenRiach acquisition occurred during the first fiscal quarter of 2017 and the purchase price allocation was finalized as of June 1, 2017. There have been no material changes to the purchase price allocation. As discussed in Note 11, our shares of common stock were split during February 2018 through the issuance of a stock dividend. As a result, all share and per share amounts reported in the accompanying financial statements and related notes are presented on a split-adjusted basis. New accounting pronouncements to be adopted. In May 2014, the Financial Accounting Standards Board (FASB) issued a new revenue recognition standard that, along with various amendments issued in 2015 and 2016, will replace substantially all existing revenue recognition guidance in U.S. GAAP. The core principle of the standard requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to in exchange for those goods or services. The new standard also requires significantly more financial statement disclosures than existing revenue standards do. The new standard can be adopted using either of two transition options: a full retrospective transition method or a modified retrospective method. Under the full retrospective method, the guidance would be applied to each prior reporting period presented. Under the modified retrospective method, the cumulative effect of initially applying the new guidance would be recorded as an adjustment to the opening balance of retained earnings for the annual reporting period that includes the date of initial application. We are continuing to assess the potential impact of the new guidance on our financial statements. Based on our assessment to date, we currently expect our accounting for certain customer incentives to be the area most likely affected by the new recognition requirements. We also expect to disclose additional information about revenues under the new standard. As we progress in our assessment, we are also identifying and preparing to make any changes to our accounting policies and practices, systems, processes, and controls that may be required to implement the new standard. We currently expect to choose the modified retrospective method in transitioning to the new standard, which we will adopt effective May 1, 2018. We are also currently evaluating the potential impact on our financial statements of the additional new accounting pronouncements described below: • In February 2016, the FASB issued a new standard on accounting for leases. Under the new standard, a lessee should recognize on its balance sheet a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. The standard permits an entity to make an accounting policy election not to recognize lease assets and liabilities for leases with a term of 12 months or less. The standard, which also requires additional quantitative and qualitative disclosures about leasing arrangements, will become effective for us beginning fiscal 2020. It is to be applied using a modified retrospective transition approach for leases existing at the beginning of the earliest comparative period presented in the adoption-period financial statements. • In August 2016, the FASB issued new guidance on the classification of certain cash receipts and cash payments on the statement of cash flows. The new guidance, which addresses eight specific cash flow classification issues, is intended to reduce diversity in practice. It will become effective for us beginning fiscal 2019 and is to be applied retrospectively. • In October 2016, the FASB issued revised guidance that requires the recognition of the income tax consequences (expense or benefit) of an intercompany transfer of assets other than inventory when the transfer occurs. It maintains the existing requirement to defer the recognition of the income tax consequences of an intercompany transfer of inventory until the inventory is sold to an outside party. The guidance will become effective for us beginning fiscal 2019 and is to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. • In January 2017, the FASB issued updated guidance that eliminates the second step of the existing two-step quantitative test of goodwill for impairment. Under the new guidance, the quantitative test will consist of a single step in which the carrying amount of the reporting unit will be compared to its fair value. An impairment charge would be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the amount of the impairment would be limited to the total amount of goodwill allocated to the reporting unit. The guidance does not affect the existing option to perform the qualitative assessment for a reporting unit to determine whether the quantitative impairment test is necessary. Although adoption is not required until fiscal 2021, we currently expect to adopt the new standard, prospectively, beginning in fiscal 2019. • In March 2017, the FASB issued new guidance for the presentation of the net periodic cost (NPC) associated with pension and other postretirement benefit plans. The guidance requires the service cost component of the NPC to be reported in the income statement in the same line item(s) as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of the NPC are to be presented separately from the service cost and outside of income from operations. In addition, the guidance allows only the service cost component of NPC to be eligible for capitalization when applicable. The guidance will become effective for us beginning fiscal 2019. It is to be applied retrospectively for the presentation in the income statement and prospectively, on and after the effective date, for the capitalization of service cost. • In August 2017, the FASB issued updated guidance on hedge accounting. The guidance expands hedge accounting for financial and nonfinancial risk components, eliminates the requirement to separately measure and report hedge ineffectiveness, simplifies the way assessments of hedge effectiveness may be performed, and amends some presentation and disclosure requirements for hedges. The guidance will become effective for us beginning fiscal 2020. It is to be applied using a modified retrospective transition approach for cash flow and net investment hedges existing at the date of adoption. The amended presentation and disclosure guidance is required only prospectively. Although we have not yet determined our plans for adoption, we are considering the possibility of adopting this new guidance before the required adoption date. • In February 2018, the FASB issued guidance that would allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act enacted by the U.S. government in December 2017. The guidance will become effective for us beginning fiscal 2020. It is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. Early adoption of any of the new accounting pronouncements described above is permitted. However, except as noted above, we do not currently expect to adopt the new pronouncements before their effective dates.

Inventory Disclosure [Abstract]
Inventories	Inventories Inventories are valued at the lower of cost or market. Some of our consolidated inventories are valued using the last-in, first-out (LIFO) method, which we use for the majority of our U.S. inventories. If the LIFO method had not been used, inventories at current cost would have been $272 million higher than reported as of April 30, 2017 , and $293 million higher than reported as of January 31, 2018 . Changes in the LIFO valuation reserve for interim periods are based on a proportionate allocation of the estimated change for the entire fiscal year.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our consolidated interim effective tax rate is based upon our expected annual operating income, statutory tax rates, and income tax laws in the various jurisdictions in which we operate. Significant or unusual items, including adjustments to accruals for tax uncertainties, are recognized in the quarter in which the related event or a change in judgment occurs. The effective tax rate of 28.5% for the nine months ended January 31, 2018 , is higher than the expected tax rate of 26.1% on ordinary income for the full fiscal year, primarily due to (a) the net impact of the Tax Cuts and Jobs Act (discussed below) and (b) true-ups related to our recently-filed U.S. Federal income tax return, partially offset by (c) the excess tax benefits related to stock-based compensation and (d) a reduction in U.S. tax recorded in the first quarter of fiscal 2018 for certain prior years on foreign exchange gains in non-U.S. entities due to a change in method of accounting for U.S. tax purposes. Our expected tax rate includes current fiscal year additions for existing tax contingency items. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act significantly revises the future ongoing U.S. corporate income tax by, among other things, lowering U.S. corporate income tax rates and implementing a territorial tax system. As we have an April 30 fiscal year-end, the lower corporate income tax rate will be phased in, resulting in a U.S. statutory federal rate of 30.4% for our fiscal year ending April 30, 2018, and 21% for subsequent fiscal years. During the quarter ended January 31, 2018, the impact of the lower tax rate resulted in a tax benefit of approximately $20 million for the three and nine months then ended. With the enactment of the Tax Act, we are evaluating our global working capital requirements and may change our current permanent reinvestment assertion in future periods. There are also certain transitional impacts of the Tax Act. As part of the transition to the new territorial tax system, the Tax Act imposes a one-time repatriation tax on deemed repatriation of historical earnings of foreign subsidiaries. In addition, the reduction of the U.S. corporate tax rate required us to adjust our U.S. deferred tax assets and liabilities to the lower federal base rate of 21% . These transitional impacts resulted in a provisional net charge of $43 million for the quarter ended January 31, 2018, comprised of a provisional repatriation U.S. tax charge of $91 million and a provisional net deferred tax benefit of $48 million . The Tax Act also established new tax laws that may impact our financial statements beginning in fiscal 2019. These new laws include, but are not limited to (a) Global Intangible Low-Tax Income (“GILTI”), a new tax on low tax foreign jurisdictions, (b) Base Erosion Anti-abuse Tax (“BEAT”), a new minimum tax, (c) repeal of the domestic production activity deduction, and (d) limitations on certain executive compensation. The changes included in the Tax Act are broad and complex. The final transition impacts of the Tax Act may differ from the above estimates, due to, among other things, changes in interpretations of the Tax Act, any legislative action to address questions that arise because of the Tax Act, any changes in accounting standards for income taxes or related interpretations in response to the Tax Act, or any updates or changes to estimates the company has utilized to calculate the transition impacts, including impacts from changes to current year earnings estimates and foreign exchange rates of foreign subsidiaries. Shortly after the Tax Act was enacted, the U.S. Securities and Exchange Commission issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (SAB 118). Under SAB 118, companies are provided a measurement period, not to extend beyond one year since the date of enactment. To the extent a company’s accounting for certain income tax effects are incomplete, the company may determine a reasonable estimate and record a provisional amount within the first reporting period in which a reasonable estimate can be determined.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share We calculate basic earnings per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share further includes the dilutive effect of stock-based compensation awards. We calculate that dilutive effect using the “treasury stock method” (as defined by GAAP). The following table presents information concerning basic and diluted earnings per share: Three Months Ended Nine Months Ended January 31, January 31, (Dollars in millions, except per share amounts) 2017 2018 2017 2018 Net income available to common stockholders $ 182 $ 190 $ 524 $ 607 Share data (in thousands): Basic average common shares outstanding 480,650 480,361 486,105 480,193 Dilutive effect of stock-based awards 3,308 3,883 3,515 3,318 Diluted average common shares outstanding 483,958 484,244 489,620 483,511 Basic earnings per share $ 0.38 $ 0.39 $ 1.08 $ 1.26 Diluted earnings per share $ 0.38 $ 0.39 $ 1.07 $ 1.25 We excluded common stock-based awards for approximately 2,789,000 shares and 0 shares from the calculation of diluted earnings per share for the three months ended January 31, 2017 and 2018 , respectively. We excluded common stock-based awards for approximately 2,225,000 shares and 1,073,000 shares from the calculation of diluted earnings per share for the nine months ended January 31, 2017 and 2018 , respectively. We excluded those awards because they were not dilutive for those periods under the treasury stock method.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies We operate in a litigious environment, and we are sued in the normal course of business. Sometimes plaintiffs seek substantial damages. Significant judgment is required in predicting the outcome of these suits and claims, many of which take years to adjudicate. We accrue estimated costs for a contingency when we believe that a loss is probable and we can make a reasonable estimate of the loss, and then adjust the accrual as appropriate to reflect changes in facts and circumstances. We do not believe it is reasonably possible that these existing loss contingencies, individually or in the aggregate, would have a material adverse effect on our financial position, results of operations, or liquidity. No material accrued loss contingencies are recorded as of January 31, 2018 . We have guaranteed the repayment by a third-party importer of its obligation under a bank credit facility that it uses in connection with its importation of our products in Russia. If the importer were to default on that obligation, which we believe is unlikely, our maximum possible exposure under the existing terms of the guaranty would be approximately $12 million (subject to changes in foreign currency exchange rates). Both the fair value and carrying amount of the guaranty are insignificant. As of January 31, 2018 , our actual exposure under the guaranty of the importer’s obligation is approximately $6 million . Based on the financial support we provide to the importer, we believe it meets the definition of a variable interest entity. However, because we do not control this entity, it is not included in our consolidated financial statements.

We categorize the fair values of assets and liabilities into three levels based upon the assumptions (inputs) used to determine those values. Level 1 provides the most reliable measure of fair value, while Level 3 generally requires significant management judgment. The three levels are: • Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities. • Level 2 – Observable inputs other than those included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in inactive markets; or other inputs that are observable or can be derived from or corroborated by observable market data. • Level 3 – Unobservable inputs that are supported by little or no market activity. We determine the fair values of our currency derivatives (forward contracts) using standard valuation models. The significant inputs used in these models, which are readily available in public markets or can be derived from observable market transactions, include the applicable spot rates, forward rates, and discount rates. The discount rates are based on the historical U.S. Treasury rates. These fair value measurements are categorized as Level 2 within the valuation hierarchy. We determine the fair value of long-term debt primarily based on the prices at which similar debt has recently traded in the market and also considering the overall market conditions on the date of valuation. These fair value measurements are categorized as Level 2 within the valuation hierarchy. The fair values of cash, cash equivalents, and short-term borrowings approximate the carrying amounts due to the short maturities of these instruments. We measure some assets and liabilities at fair value on a nonrecurring basis. That is, we do not measure them at fair value on an ongoing basis, but we do adjust them to fair value in some circumstances (for example, when we determine that an asset is impaired). No material nonrecurring fair value measurements were required during the periods presented in these financial statements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments and Hedging Activities	Derivative Financial Instruments and Hedging Activities Our multinational business exposes us to global market risks, including the effect of fluctuations in currency exchange rates, commodity prices, and interest rates. We use derivatives to help manage financial exposures that occur in the normal course of business. We formally document the purpose of each derivative contract, which includes linking the contract to the financial exposure it is designed to mitigate. We do not hold or issue derivatives for trading or speculative purposes. We use currency derivative contracts to limit our exposure to the currency exchange risk that we cannot mitigate internally by using netting strategies. We designate most of these contracts as cash flow hedges of forecasted transactions (expected to occur within three years). We record all changes in the fair value of cash flow hedges (except any ineffective portion) in accumulated other comprehensive income (AOCI) until the underlying hedged transaction occurs, at which time we reclassify that amount into earnings. We assess the effectiveness of these hedges based on changes in forward exchange rates. The ineffective portion of the changes in fair value of our hedges (recognized immediately in earnings) during the periods presented in this report was not material. We had outstanding currency derivatives, related primarily to our euro, British pound, and Australian dollar exposures, with notional amounts totaling $1,188 million at April 30, 2017 and $1,100 million at January 31, 2018 . During fiscal 2017, we designated some currency derivative forward contracts and foreign currency-denominated long-term debt as after-tax net investment hedges of our investments in certain foreign subsidiaries. During fiscal 2018, we have continued to designate some foreign currency-denominated debt for that purpose. Any change in value of the designated portion of the hedging instruments is recorded in AOCI, offsetting the foreign currency translation adjustment of the related net investments that is also recorded in AOCI. As of January 31, 2018, $649 million of our foreign currency-denominated debt was designated as a net investment hedge. Our net investment hedges are intended to mitigate foreign exchange exposure related to non-U.S. dollar net investments in certain foreign subsidiaries against changes in foreign exchange rates. There was no ineffectiveness related to our net investment hedges in any of the periods presented. We do not designate some of our currency derivatives and foreign currency-denominated debt as hedges because we use them to at least partially offset the immediate earnings impact of changes in foreign exchange rates on existing assets or liabilities. We immediately recognize the change in fair value of these instruments in earnings. We use forward purchase contracts with suppliers to protect against corn price volatility. We expect to physically take delivery of the corn underlying each contract and use it for production over a reasonable period of time. Accordingly, we account for these contracts as normal purchases rather than as derivative instruments. The following tables present the pre-tax impact that changes in the fair value of our derivative instruments and non-derivative hedging instruments had on AOCI and earnings: Three Months Ended January 31, (Dollars in millions) Classification 2017 2018 Derivative Instruments Currency derivatives designated as cash flow hedges: Net gain (loss) recognized in AOCI n/a $ 5 $ (51 ) Net gain (loss) reclassified from AOCI into earnings Sales 15 (1 ) Currency derivatives not designated as hedging instruments: Net gain (loss) recognized in earnings Sales — (5 ) Net gain (loss) recognized in earnings Other income (5 ) 3 Non-Derivative Hedging Instruments Foreign currency-denominated debt designated as net investment hedge: Net gain (loss) recognized in AOCI n/a (5 ) (42 ) Foreign currency-denominated debt not designated as hedging instrument: Net gain (loss) recognized in earnings Other income 4 (9 ) Nine Months Ended January 31, (Dollars in millions) Classification 2017 2018 Derivative Instruments Currency derivatives designated as cash flow hedges: Net gain (loss) recognized in AOCI n/a $ 57 $ (80 ) Net gain (loss) reclassified from AOCI into earnings Sales 34 (4 ) Currency derivatives designated as net investment hedge: Net gain (loss) recognized in AOCI n/a 8 — Currency derivatives not designated as hedging instruments: Net gain (loss) recognized in earnings Sales 3 (8 ) Net gain (loss) recognized in earnings Other income (13 ) 8 Non-Derivative Hedging Instruments Foreign currency-denominated debt designated as net investment hedge: Net gain (loss) recognized in AOCI n/a 19 (57 ) Foreign currency-denominated debt not designated as hedging instrument: Net gain (loss) recognized in earnings Other income 6 (24 ) We expect to reclassify $34 million of deferred net losses on cash flow hedges recorded in AOCI as of January 31, 2018 , to earnings during the next 12 months. This reclassification would offset the anticipated earnings impact of the underlying hedged exposures. The actual amounts that we ultimately reclassify to earnings will depend on the exchange rates in effect when the underlying hedged transactions occur. As of January 31, 2018 , the maximum term of our outstanding derivative contracts was 36 months . The following table presents the fair values of our derivative instruments: (Dollars in millions) Classification Fair value of derivatives in a gain position Fair value of derivatives in a loss position April 30, 2017: Designated as cash flow hedges: Currency derivatives Other current assets $ 21 $ (2 ) Currency derivatives Other assets 9 (4 ) Currency derivatives Accrued expenses 2 (8 ) Currency derivatives Other liabilities 1 (4 ) Not designated as hedges: Currency derivatives Other current assets 2 (1 ) Currency derivatives Accrued expenses — (1 ) January 31, 2018: Designated as cash flow hedges: Currency derivatives Other current assets — — Currency derivatives Other assets — — Currency derivatives Accrued expenses 4 (40 ) Currency derivatives Other liabilities 1 (34 ) Not designated as hedges: Currency derivatives Other current assets 3 (1 ) Currency derivatives Accrued expenses — — The fair values reflected in the above table are presented on a gross basis. However, as discussed further below, the fair values of those instruments that are subject to net settlement agreements are presented in our balance sheets on a net basis. In our statement of cash flows, we classify cash flows related to cash flow hedges in the same category as the cash flows from the hedged items. Credit risk. We are exposed to credit-related losses if the counterparties to our derivative contracts default. This credit risk is limited to the fair value of the contracts. To manage this risk, we contract only with major financial institutions that have earned investment-grade credit ratings and with whom we have standard International Swaps and Derivatives Association (ISDA) agreements that allow for net settlement of the derivative contracts. Also, we have established counterparty credit guidelines that are regularly monitored, and we monetize contracts when we believe it is warranted. Because of these safeguards, we believe we have no derivative positions that warrant credit valuation adjustments. Some of our derivative instruments require us to maintain a specific level of creditworthiness, which we have maintained. If our creditworthiness were to fall below that level, then the counterparties to our derivative instruments could request immediate payment or collateralization for derivative instruments in net liability positions. The aggregate fair value of all derivatives with creditworthiness requirements that were in a net liability position was $9 million at April 30, 2017 and $67 million at January 31, 2018 . Offsetting. As noted above, our derivative contracts are governed by ISDA agreements that allow for net settlement of derivative contracts with the same counterparty. It is our policy to present the fair values of current derivatives (i.e., those with a remaining term of 12 months or less) with the same counterparty on a net basis in the balance sheet. Similarly, we present the fair values of noncurrent derivatives with the same counterparty on a net basis. Current derivatives are not netted with noncurrent derivatives in the balance sheet. The following table summarizes the gross and net amounts of our derivative contracts: (Dollars in millions) Gross Amounts of Recognized Assets (Liabilities) Gross Amounts Offset in Balance Sheet Net Amounts Presented in Balance Sheet Gross Amounts Not Offset in Balance Sheet Net Amounts April 30, 2017: Derivative assets $ 35 $ (10 ) $ 25 $ (1 ) $ 24 Derivative liabilities (20 ) 10 (10 ) 1 (9 ) January 31, 2018: Derivative assets 8 (6 ) 2 (2 ) — Derivative liabilities (75 ) 6 (69 ) 2 (67 ) No cash collateral was received or pledged related to our derivative contracts as of April 30, 2017 or January 31, 2018 .

On May 24, 2017, we retired 67,000,000 shares of Class B common stock previously held as treasury shares. This retirement reduced the number of issued shares of Class B common stock by that same amount . On January 23, 2018, our Board of Directors approved a stock split, effected in the form of a stock dividend. For every four shares of either Class A or Class B common stock held, shareholders of record as of the close of business on February 7, 2018, received one share of Class B common stock, with any fractional shares payable in cash.
