	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, 2013 (the 2013 Form 10-K).
	In our opinion, the accompanying financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of our financial results for the periods covered by this report.
	We prepared the accompanying financial statements on a basis that is substantially consistent with the accounting principles applied in our 2013 Form 10-K, although during the first quarter of fiscal 2014 we adopted new guidance for disclosures about offsetting assets and liabilities and for reporting amounts reclassified out of accumulated other comprehensive income. Our adoption of the new guidance had no material impact on our financial statements.

	We use the last-in, first-out (LIFO) method to determine the cost of most of our inventories. If the LIFO method had not been used, inventories at current cost would have been $209 million higher than reported as of April 30, 2013, and $213 million higher than reported as of October 31, 2013. 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 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 occurs. The effective tax rate of 32.4% for the six months ended October 31, 2013, is based on an expected tax rate of 31.8% on ordinary income for the full fiscal year, as adjusted for the recognition of net tax expense related to discrete items arising during the period and interest on previously provided tax contingencies. Our expected tax rate includes current fiscal year additions for existing tax contingency items.
	We believe there will be no material change in our gross unrecognized tax benefits in the next 12 months.
	We file income tax returns in the United States, including several state and local jurisdictions, as well as in several other countries in which we conduct business. The major jurisdictions and their earliest fiscal years that are currently open for tax examinations are 2006 in the United States, 2009 in Ireland and Italy, 2008 in Australia and Poland, 2007 in Finland, 2003 in the U.K., and 2002 in Mexico. The audit of our fiscal 2012 U.S. federal tax return was concluded during the current fiscal year.  In addition, we are participating in the Internal Revenue Service’s Compliance Assurance Program for our fiscal 2013 and 2014 tax years.

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, including stock options, stock-settled stock appreciation rights, restricted stock units, deferred stock units, and shares of restricted stock. We calculate that dilutive effect using the “treasury stock method” (as defined by GAAP).
	Some restricted shares have non-forfeitable rights to dividends declared on common stock. As a result, these restricted shares are considered participating securities in the calculation of earnings per share.
	The following table presents information concerning basic and diluted earnings per share:
		Three Months Ended				Six Months Ended

	(Dollars in millions, except per share amounts)	2012		2013		2012		2013

	Diluted earnings per share	$	0.8	$	0.96	$	1.49	$	1.62
	We excluded common stock-based awards for approximately 508,000 shares and 410,000 shares from the calculation of diluted earnings per share for the three months ended October 31, 2012 and 2013, respectively. We excluded common stock-based awards for approximately 534,000 shares and 412,000 shares from the calculation of diluted earnings per share for the six months ended October 31, 2012 and 2013, respectively. We excluded those awards because they were not dilutive for those periods under the treasury stock method.

Contingencies	'
	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 these 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 October 31, 2013.
	We have guaranteed the obligations of a third-party’s bank credit facility used in connection with its importation of our products in a foreign market. Our maximum exposure under the guarantee is approximately $47 million should the third-party importer default on its obligation, which we believe is unlikely. As of October 31, 2013, our exposure under the guarantee is approximately $45 million. Both the fair value and carrying amount of the guarantee are insignificant.

	Fair Value Measurements
	Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. 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 markets that are not active; 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.
	The following table summarizes the assets and liabilities measured at fair value on a recurring basis:

	Current portion of long-term debt		—		1		—		1
	Long-term debt		—		954		—		954
	We determine the fair values of our currency derivatives (forwards and options) using standard valuation models. The significant inputs used in these models are readily available in public markets or can be derived from observable market transactions. Inputs used in these standard valuation models include the applicable exchange rate, forward rates and discount rates for the currency derivatives. The standard valuation model for foreign currency options also uses implied volatility as an additional input. The discount rates are based on the historical U.S. Treasury rates, and the implied volatility specific to individual foreign currency options is based on quoted rates from financial institutions.
	The fair value of short-term borrowings approximates the carrying amount. 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.
	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	'
	Derivative Financial Instruments
	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 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 do not designate some of our currency derivatives 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 contracts in earnings.
	We had outstanding currency derivatives, related primarily to our euro, British pound, and Australian dollar exposures, with total notional amounts totaling $686 million at April 30, 2013 and $583 million at October 31, 2013.
	Prior to July 31, 2012, we utilized exchange-traded futures and options contracts to mitigate our exposure to corn price volatility. Because we did not designate these contracts as hedges for accounting purposes, we immediately recognized changes in their fair value in earnings. Effective July 31, 2012, we instead 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 derivative instruments.
	From time to time, we manage our interest rate risk with swap contracts. However, no such swaps were outstanding at
	April 30, 2013 or October 31, 2013.
	The following tables present the amounts affecting our consolidated statements of operations for the periods covered by this report:

	We expect to reclassify $4 million of deferred net losses recorded in AOCI as of October 31, 2013, 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. The maximum term of our outstanding derivative contracts was 24 months at April 30, 2013 and 22 months at October 31, 2013.
	The following table presents the fair values of our derivative instruments as of April 30, 2013 and October 31, 2013.

	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 on a net basis in the accompanying consolidated balance sheets.
	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 that provide for reports to senior management according to prescribed guidelines, and we monetize contracts when we believe it is warranted. Because of these safeguards, we believe the risk of loss from counterparty default to be immaterial.
	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 $2 million at April 30, 2013 and $9 million at October 31, 2013.
	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

	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
