BASIS OF PRESENTATION AND RECLASSIFICATIONS [Abstract]	'
BASIS OF PRESENTATION AND RECLASSIFICATIONS	'
	NOTE 1. BASIS OF PRESENTATION AND RECLASSIFICATIONS
	Basis of Presentation
	Our Consolidated Financial Statements include the accounts of General Mills, Inc. and all subsidiaries in which we have a controlling financial interest. Intercompany transactions and accounts, including any noncontrolling and redeemable interests' share of those transactions, are eliminated in consolidation.
	Our fiscal year ends on the last Sunday in May. Fiscal years 2014, 2013 and 2012 each consisted of 52 weeks.
	Change in Reporting Period
	As part of a long-term plan to conform the fiscal year ends of all our operations, we have changed the reporting period of certain countries within our International segment from an April fiscal year end to a May fiscal year end to match our fiscal calendar. Accordingly, in the year of change, our results include 13 months of results from the affected operations compared to 12 months in previous fiscal years. We changed the reporting period for our operations in Europe and Australia in fiscal 2013, and we changed the reporting period for our operations in China in fiscal 2012. The impact of these changes was not material to our consolidated results of operations and, therefore, we did not restate prior period financial statements for comparability. Our Yoplait S.A.S., Yoplait Marques S.A.S., Yoki Alimentos S.A. (Yoki), and India businesses remain on an April fiscal year end.
	Certain reclassifications to our previously reported financial information have been made to conform to the current period presentation.

SUMMARY_OF_SIGNIFICANT_ACCOUNT

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	25-May-14
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]	'
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Cash and Cash Equivalents
	We consider all investments purchased with an original maturity of three months or less to be cash equivalents.
	Inventories
	All inventories in the United States other than grain are valued at the lower of cost, using the last-in, first-out (LIFO) method, or market. Grain inventories and all related cash contracts and derivatives are valued at market with all net changes in value recorded in earnings currently.
	Inventories outside of the United States are generally valued at the lower of cost, using the first-in, first-out (FIFO) method, or market.
	Shipping costs associated with the distribution of finished product to our customers are recorded as cost of sales, and are recognized when the related finished product is shipped to and accepted by the customer.
	Land, Buildings, Equipment, and Depreciation
	Land is recorded at historical cost. Buildings and equipment, including capitalized interest and internal engineering costs, are recorded at cost and depreciated over estimated useful lives, primarily using the straight-line method. Ordinary maintenance and repairs are charged to cost of sales. Buildings are usually depreciated over 40 to 50 years, and equipment, furniture, and software are usually depreciated over 3 to 10 years. Fully depreciated assets are retained in buildings and equipment until disposal. When an item is sold or retired, the accounts are relieved of its cost and related accumulated depreciation and the resulting gains and losses, if any, are recognized in earnings. As of May 25, 2014, assets held for sale were insignificant.
	Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset (or asset group) may not be recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows from the operation and disposition of the asset group are less than the carrying amount of the asset group. Asset groups have identifiable cash flows and are largely independent of other asset groups. Measurement of an impairment loss would be based on the excess of the carrying amount of the asset group over its fair value. Fair value is measured using a discounted cash flow model or independent appraisals, as appropriate.
	Goodwill and Other Intangible Assets
	Goodwill is not subject to amortization and is tested for impairment annually and whenever events or changes in circumstances indicate that impairment may have occurred. Impairment testing is performed for each of our reporting units. We compare the carrying value of a reporting unit, including goodwill, to the fair value of the unit. Carrying value is based on the assets and liabilities associated with the operations of that reporting unit, which often requires allocation of shared or corporate items among reporting units. If the carrying amount of a reporting unit exceeds its fair value, we revalue all assets and liabilities of the reporting unit, excluding goodwill, to determine if the fair value of the net assets is greater than the net assets including goodwill. If the fair value of the net assets is less than the carrying amount of net assets including goodwill, impairment has occurred. Our estimates of fair value are determined based on a discounted cash flow model. Growth rates for sales and profits are determined using inputs from our long-range planning process. We also make estimates of discount rates, perpetuity growth assumptions, market comparables, and other factors.
	We evaluate the useful lives of our other intangible assets, mainly brands, to determine if they are finite or indefinite-lived. Reaching a determination on useful life requires significant judgments and assumptions regarding the future effects of obsolescence, demand, competition, other economic factors (such as the stability of the industry, known technological advances, legislative action that results in an uncertain or changing regulatory environment, and expected changes in distribution channels), the level of required maintenance expenditures, and the expected lives of other related groups of assets. Intangible assets that are deemed to have definite lives are amortized on a straight-line basis, over their useful lives, generally ranging from 4 to 30 years.
	Our indefinite-lived intangible assets, mainly intangible assets primarily associated with the Pillsbury, Totino's, Progresso, Green Giant, Yoplait, Old El Paso, Yoki, and Häagen-Dazs brands, are also tested for impairment annually and whenever events or changes in circumstances indicate that their carrying value may not be recoverable. We performed our fiscal 2014 assessment of our brand intangibles as of November 25, 2013. Our estimate of the fair value of the brands was based on a discounted cash flow model using inputs which included projected revenues from our long-range plan, assumed royalty rates that could be payable if we did not own the brands, and a discount rate.
	Our finite-lived intangible assets, primarily acquired franchise agreements and customer relationships, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows from the operation and disposition of the asset are less than the carrying amount of the asset. Assets generally have identifiable cash flows and are largely independent of other assets. Measurement of an impairment loss would be based on the excess of the carrying amount of the asset over its fair value. Fair value is measured using a discounted cash flow model or other similar valuation model, as appropriate.
	Investments in Joint Ventures
	Our investments in companies over which we have the ability to exercise significant influence are stated at cost plus our share of undistributed earnings or losses. We receive royalty income from certain joint ventures, incur various expenses (primarily research and development), and record the tax impact of certain joint venture operations that are structured as partnerships. In addition, we make advances to our joint ventures in the form of loans or capital investments. We also sell certain raw materials, semi-finished goods, and finished goods to the joint ventures, generally at market prices.
	In addition, we assess our investments in our joint ventures if we have reason to believe an impairment may have occurred including, but not limited to, ongoing operating losses, projected decreases in earnings, increases in the weighted average cost of capital or significant business disruptions. The significant assumptions used to estimate fair value include revenue growth and profitability, royalty rates, capital spending, depreciation and taxes, foreign currency exchange rates, and a discount rate. By their nature, these projections and assumptions are uncertain. If we were to determine the current fair value of our investment was less than the carrying value of the investment, then we would assess if the shortfall was of a temporary or permanent nature and write down the investment to its fair value if we concluded the impairment is other than temporary.
	Redeemable Interest
	We have a 51 percent controlling interest in Yoplait S.A.S., a consolidated entity. Sodiaal International (Sodiaal) holds the remaining 49 percent interest in Yoplait S.A.S. Sodiaal has the ability to put a limited portion of its redeemable interest to us at fair value once per year up to a maximum remaining term of 6 years. This put option requires us to classify Sodiaal's interest as a redeemable interest outside of equity on our Consolidated Balance Sheets for as long as the put is exercisable by Sodiaal. When the put is no longer exercisable, the redeemable interest will be reclassified to noncontrolling interests on our Consolidated Balance Sheets. We adjust the value of the redeemable interest through additional paid-in capital on our Consolidated Balance Sheets quarterly to the redeemable interest's redemption value, which approximates its fair value. During the third quarter of fiscal 2014, we adjusted the redeemable interest's redemption value based on a discounted cash flow model. The significant assumptions used to estimate the redemption value include projected revenue growth and profitability from our long-range plan, capital spending, depreciation, taxes, foreign currency rates, and a discount rate.
	Revenue Recognition
	We recognize sales revenue when the shipment is accepted by our customer. Sales include shipping and handling charges billed to the customer and are reported net of consumer coupon redemption, trade promotion and other costs, including estimated allowances for returns, unsalable product, and prompt pay discounts. Sales, use, value-added, and other excise taxes are not recognized in revenue. Coupons are recorded when distributed, based on estimated redemption rates. Trade promotions are recorded based on estimated participation and performance levels for offered programs at the time of sale. We generally do not allow a right of return. However, on a limited case-by-case basis with prior approval, we may allow customers to return product. In limited circumstances, product returned in saleable condition is resold to other customers or outlets. Receivables from customers generally do not bear interest. Terms and collection patterns vary around the world and by channel. The allowance for doubtful accounts represents our estimate of probable non-payments and credit losses in our existing receivables, as determined based on a review of past due balances and other specific account data. Account balances are written off against the allowance when we deem the amount is uncollectible.
	Environmental
	Environmental costs relating to existing conditions caused by past operations that do not contribute to current or future revenues are expensed. Liabilities for anticipated remediation costs are recorded on an undiscounted basis when they are probable and reasonably estimable, generally no later than the completion of feasibility studies or our commitment to a plan of action.
	Advertising Production Costs
	We expense the production costs of advertising the first time that the advertising takes place.
	Research and Development
	All expenditures for research and development (R&D) are charged against earnings in the year incurred. R&D includes expenditures for new product and manufacturing process innovation, and the annual expenditures are comprised primarily of internal salaries, wages, consulting, and other supplies attributable to time spent on R&D activities. Other costs include depreciation and maintenance of research facilities, including assets at facilities that are engaged in pilot plant activities.
	Foreign Currency Translation
	For all significant foreign operations, the functional currency is the local currency. Assets and liabilities of these operations are translated at the period-end exchange rates. Income statement accounts are translated using the average exchange rates prevailing during the year. Translation adjustments are reflected within accumulated other comprehensive loss (AOCI) in stockholders' equity. Gains and losses from foreign currency transactions are included in net earnings for the period, except for gains and losses on investments in subsidiaries for which settlement is not planned for the foreseeable future and foreign exchange gains and losses on instruments designated as net investment hedges. These gains and losses are recorded in AOCI.
	Derivative Instruments
	All derivatives are recognized on the Consolidated Balance Sheets at fair value based on quoted market prices or our estimate of their fair value, and are recorded in either current or noncurrent assets or liabilities based on their maturity. Changes in the fair values of derivatives are recorded in net earnings or other comprehensive income, based on whether the instrument is designated and effective as a hedge transaction and, if so, the type of hedge transaction. Gains or losses on derivative instruments reported in AOCI are reclassified to earnings in the period the hedged item affects earnings. If the underlying hedged transaction ceases to exist, any associated amounts reported in AOCI are reclassified to earnings at that time. Any ineffectiveness is recognized in earnings in the current period.
	Stock-based Compensation
	We generally measure compensation expense for grants of restricted stock units using the value of a share of our stock on the date of grant. We estimate the value of stock option grants using a Black-Scholes valuation model. Stock compensation is recognized straight line over the vesting period. Our stock compensation expense is recorded in selling, general and administrative (SG&A) expenses and cost of sales in the Consolidated Statements of Earnings and allocated to each reportable segment in our segment results.
	Certain equity-based compensation plans contain provisions that accelerate vesting of awards upon retirement, termination, or death of eligible employees and directors. We consider a stock-based award to be vested when the employee's retention of the award is no longer contingent on providing subsequent service. Accordingly, the related compensation cost is recognized immediately for awards granted to retirement-eligible individuals or over the period from the grant date to the date retirement eligibility is achieved, if less than the stated vesting period.
	We report the benefits of tax deductions in excess of recognized compensation cost as a financing cash flow, thereby reducing net operating cash flows and increasing net financing cash flows.
	Defined Benefit Pension, Other Postretirement Benefit, and Postemployment Benefit Plans
	We sponsor several domestic and foreign defined benefit plans to provide pension, health care, and other welfare benefits to retired employees. Under certain circumstances, we also provide accruable benefits to former or inactive employees in the United States and Canada and members of our Board of Directors, including severance and certain other benefits payable upon death. We recognize an obligation for any of these benefits that vest or accumulate with service. Postemployment benefits that do not vest or accumulate with service (such as severance based solely on annual pay rather than years of service) are charged to expense when incurred. Our postemployment benefit plans are unfunded.
	We recognize the underfunded or overfunded status of a defined benefit pension plan as an asset or liability and recognize changes in the funded status in the year in which the changes occur through AOCI.
	Use of Estimates
	Preparing our Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates include our accounting for promotional expenditures, valuation of long-lived assets, intangible assets, redeemable interest, stock-based compensation, income taxes, and defined benefit pension, postretirement and postemployment benefits. Actual results could differ from our estimates.

	NOTE 3. ACQUISITIONS
	During the fourth quarter of fiscal 2014, we sold certain grain elevators in our U.S. Retail segment for $121.6 million in cash, subject to a working capital adjustment, and recorded a pre-tax gain of $65.5 million.
	On August 1, 2012, we acquired Yoki, a privately held food company headquartered in Sao Bernardo do Campo, Brazil, for an aggregate purchase price of $939.8 million, including $88.8 million of non-cash consideration for net debt assumed. Yoki operates in several food categories, including snacks, convenient meals, basic foods, and seasonings. We consolidated Yoki into our Consolidated Balance Sheets and recorded goodwill of $363.0 million. Indefinite lived intangible assets acquired include brands of $253.0 million. Finite lived intangible assets acquired primarily include customer relationships of $17.5 million. The pro forma effects of this acquisition were not material.

RESTRUCTURING, IMPAIRMENT, AND OTHER EXIT COSTS	'
	NOTE 4. RESTRUCTURING, IMPAIRMENT, AND OTHER EXIT COSTS
	We view our restructuring activities as actions that help us meet our long-term growth targets. Activities we undertake must meet internal rate of return and net present value targets. Each restructuring action normally takes one to two years to complete. At completion (or as each major stage is completed in the case of multi-year programs), the project begins to deliver cash savings and/or reduced depreciation. These activities result in various restructuring costs, including asset write-offs, exit charges including severance, contract termination fees, and decommissioning and other costs. Depreciation associated with restructured assets, as used in the context of our disclosures regarding restructuring activity, refers to the increase in depreciation expense caused by shortening the useful life or updating the salvage value of depreciable fixed assets to coincide with the end of production under an approved restructuring plan. Any impairment of the asset is recognized immediately in the period the plan is approved.
	In fiscal 2014, we recorded restructuring, impairment, and other exit costs pursuant to approved plans as follows:
	Expense, in Millions
	Charges associated with restructuring actions previously announced	$	3.6
	Total	$	3.6
	In fiscal 2014, the restructuring charge related to a productivity and cost savings plan approved in the fourth quarter of fiscal 2012. These restructuring actions were completed in fiscal 2014. In fiscal 2014, we paid $22.4 million in cash related to restructuring actions.
	In fiscal 2013, we recorded restructuring, impairment, and other exit costs pursuant to approved plans as follows:
	Expense, in Millions
	Charges associated with restructuring actions previously announced		19.8
	Total	$	19.8
	In fiscal 2013, the restructuring charge was primarily related to a productivity and cost savings plan approved in the fourth quarter of fiscal 2012, consisting of $10.6 million of employee severance expense and other exit costs of $8.0 million. In fiscal 2013, we paid $79.9 million in cash related to restructuring actions.
	In fiscal 2012, we recorded restructuring, impairment, and other exit costs pursuant to approved plans as follows:
	Expense, in Millions
	Productivity and cost savings plan	$	100.6
	Charges associated with restructuring actions previously announced		1
	Total	$	101.6
	In fiscal 2012, we recorded a $100.6 million restructuring charge related to a productivity and cost savings plan approved in the fourth quarter of fiscal 2012. The plan was designed to improve organizational effectiveness and focus on key growth strategies, and included organizational changes to strengthen business alignment and actions to accelerate administrative efficiencies across all of our operating segments and support functions. In connection with this initiative, we eliminated approximately 850 positions globally. The restructuring charge consisted of $87.6 million of employee severance expense and a non-cash charge of $13.0 million related to the write-off of certain long-lived assets in our U.S. Retail segment. All of our operating segments and support functions were affected by these actions including $69.9 million related to our U.S. Retail segment, $12.2 million related to our Convenience Stores and Foodservice segment, $9.5 million related to our International segment, and $9.0 million related to our administrative functions. In fiscal 2012, we paid $3.8 million in cash related to restructuring actions taken in fiscal 2012 and previous years.
	The roll forward of our restructuring and other exit cost reserves, included in other current liabilities, is as follows:
	In Millions		Severance		Contract Termination		Other Exit Costs		Total

	FINANCIAL INSTRUMENTS
	The carrying values of cash and cash equivalents, receivables, accounts payable, other current liabilities, and notes payable approximate fair value. Marketable securities are carried at fair value. As of May 25, 2014, and May 26, 2013, a comparison of cost and market values of our marketable debt and equity securities is as follows:
		Cost					Market Value					Gross Gains					Gross Losses
		Fiscal Year					Fiscal Year					Fiscal Year					Fiscal Year

	Total	$	320.4	$	135.8		$	326	$	140.5		$	5.6	$	4.7		$	-	$	-
	Earnings include no realized gains or losses from sales of available-for-sale marketable securities. Gains and losses are determined by specific identification. Classification of marketable securities as current or noncurrent is dependent upon our intended holding period, the security's maturity date, or both. The aggregate unrealized gains and losses on available-for-sale securities, net of tax effects, are classified in AOCI within stockholders' equity.
	Scheduled maturities of our marketable securities are as follows:
			Available for Sale
	In Millions		Cost		Market Value
	Under 1 year (current)	$	316.9	$	317.1
	From 1 to 3 years		1.1		1.1
	From 4 to 7 years		0.6		0.6
	Equity securities		1.8		7.2
	Total	$	320.4	$	326
	Marketable securities with a market value of $2.3 million as of May 25, 2014, were pledged as collateral for derivative contracts. As of May 25, 2014, $43.1 million of certain accounts receivable are pledged as collateral against a foreign uncommitted line of credit.
	The fair value and carrying amounts of long-term debt, including the current portion, were $8,188.6 million and $7,674.1 million, respectively, as of May 25, 2014. The fair value of long-term debt was estimated using market quotations and discounted cash flows based on our current incremental borrowing rates for similar types of instruments. Long-term debt is a Level 2 liability in the fair value hierarchy.
	RISK MANAGEMENT ACTIVITIES
	As a part of our ongoing operations, we are exposed to market risks such as changes in interest and foreign currency exchange rates and commodity and equity prices. To manage these risks, we may enter into various derivative transactions (e.g., futures, options, and swaps) pursuant to our established policies.
	COMMODITY PRICE RISK
	Many commodities we use in the production and distribution of our products are exposed to market price risks. We utilize derivatives to manage price risk for our principal ingredients and energy costs, including grains (oats, wheat, and corn), oils (principally soybean), dairy products, natural gas, and diesel fuel. Our primary objective when entering into these derivative contracts is to achieve certainty with regard to the future price of commodities purchased for use in our supply chain. We manage our exposures through a combination of purchase orders, long-term contracts with suppliers, exchange-traded futures and options, and over-the-counter options and swaps. We offset our exposures based on current and projected market conditions and generally seek to acquire the inputs at as close to our planned cost as possible.
	We use derivatives to manage our exposure to changes in commodity prices. We do not perform the assessments required to achieve hedge accounting for commodity derivative positions. Accordingly, the changes in the values of these derivatives are recorded currently in cost of sales in our Consolidated Statements of Earnings.
	Although we do not meet the criteria for cash flow hedge accounting, we nonetheless believe that these instruments are effective in achieving our objective of providing certainty in the future price of commodities purchased for use in our supply chain. Accordingly, for purposes of measuring segment operating performance these gains and losses are reported in unallocated corporate items outside of segment operating results until such time that the exposure we are managing affects earnings. At that time we reclassify the gain or loss from unallocated corporate items to segment operating profit, allowing our operating segments to realize the economic effects of the derivative without experiencing any resulting mark-to-market volatility, which remains in unallocated corporate items.
	Unallocated corporate items for fiscal 2014, 2013 and 2012 included:
		Fiscal Year
	In Millions		2014			2013		2012
	Net loss on mark-to-market valuation of commodity positions	$	-4.9		$	-7.6	$	-122.5
	Net gain on commodity positions reclassified from unallocated corporate items to segment operating profit		51.2			13.7		35.7
	Net mark-to-market revaluation of certain grain inventories		2.2			-1.7		-17.4
	Net mark-to-market valuation of certain commodity positions recognized in unallocated corporate items	$	48.5		$	4.4	$	-104.2
	As of May 25, 2014, the net notional value of commodity derivatives was $304.9 million, of which $124.1 million related to agricultural inputs and $180.8 million related to energy inputs. These contracts relate to inputs that generally will be utilized within the next 12 months.
	INTEREST RATE RISK
	We are exposed to interest rate volatility with regard to future issuances of fixed-rate debt and existing and future issuances of floating-rate debt. Primary exposures include U.S. Treasury rates, LIBOR, Euribor, and commercial paper rates in the United States and Europe. We use interest rate swaps, forward-starting interest rate swaps, and treasury locks to hedge our exposure to interest rate changes, to reduce the volatility of our financing costs, and to achieve a desired proportion of fixed versus floating-rate debt, based on current and projected market conditions. Generally under these swaps, we agree with a counterparty to exchange the difference between fixed-rate and floating-rate interest amounts based on an agreed upon notional principal amount.
	Floating Interest Rate Exposures — Floating-to-fixed interest rate swaps are accounted for as cash flow hedges, as are all hedges of forecasted issuances of debt. Effectiveness is assessed based on either the perfectly effective hypothetical derivative method or changes in the present value of interest payments on the underlying debt. Effective gains and losses deferred to AOCI are reclassified into earnings over the life of the associated debt. Ineffective gains and losses are recorded as net interest. The amount of hedge ineffectiveness was less than $1 million in each of fiscal 2014, 2013, and 2012.
	Fixed Interest Rate Exposures — Fixed-to-floating interest rate swaps are accounted for as fair value hedges with effectiveness assessed based on changes in the fair value of the underlying debt and derivatives, using incremental borrowing rates currently available on loans with similar terms and maturities. Ineffective gains and losses on these derivatives and the underlying hedged items are recorded as net interest. The amount of hedge ineffectiveness was less than $1 million in each of fiscal 2014, 2013, and 2012.
	In advance of planned debt financing, we entered into $250.0 million of treasury locks with an average fixed rate of 1.99 percent. All of these treasury locks were cash settled for $17.9 million during the third quarter of fiscal 2014, coincident with the issuance of our $500.0 million 10-year fixed-rate notes.
	During the third quarter of fiscal 2013, we entered into swaps to convert $250.0 million of 0.875 percent fixed-rate notes due January 29, 2016, to floating rates.
	As of May 25, 2014, the pre-tax amount of cash-settled interest rate hedge gain or loss remaining in AOCI which will be reclassified to earnings over the remaining term of the related underlying debt follows:
	In Millions		Gain/(Loss)
	5.2% notes due March 17, 2015	$	-0.4
	5.7% notes due February 15, 2017		-6
	5.65% notes due February 15, 2019		2.3

	5.4% notes due June 15, 2040		-14.5
	4.15% notes due February 15, 2043		11.3
	Net pre-tax hedge loss in AOCI	$	-64.8

FOREIGN EXCHANGE RISK
Foreign currency fluctuations affect our net investments in foreign subsidiaries and foreign currency cash flows related to third party purchases, intercompany loans, product shipments, and foreign-denominated commercial paper. We are also exposed to the translation of foreign currency earnings to the U.S. dollar. Our principal exposures are to the Australian dollar, Brazilian real, British pound sterling, Canadian dollar, Chinese renminbi, euro, Japanese yen, Swiss franc, and Mexican peso. We mainly use foreign currency forward contracts to selectively hedge our foreign currency cash flow exposures. We also generally swap our foreign-denominated commercial paper borrowings and nonfunctional currency intercompany loans back to U.S. dollars or the functional currency of the entity with foreign exchange exposure; the gains or losses on these derivatives offset the foreign currency revaluation gains or losses recorded in earnings on the associated borrowings. We generally do not hedge more than 18 months forward.
As of May 25, 2014, the net notional value of foreign exchange derivatives was $1,222.9 million. The amount of hedge ineffectiveness was less than $1 million in each of fiscal 2014, 2013, and 2012.
We also have many net investments in foreign subsidiaries that are denominated in euros. We previously hedged a portion of these net investments by issuing euro-denominated commercial paper and foreign exchange forward contracts. During the second quarter of fiscal 2014, we entered into a net investment hedge for a portion of our net investment in foreign operations denominated in euros by issuing €500.0 million of euro-denominated bonds. As of May 25, 2014, we had deferred net foreign currency transaction losses of $104.3 million in AOCI associated with hedging activity.
Venezuela is a highly inflationary economy and as such, we remeasure the value of the assets and liabilities of our Venezuelan subsidiary based on the exchange rate at which we expect to remit dividends in U.S. dollars. In February 2013, the Venezuelan government devalued the bolivar by resetting the official exchange rate. The effect of the devaluation in fiscal 2013 was a $25.2 million foreign exchange loss in segment operating profit resulting from the remeasurement of assets and liabilities of our Venezuelan subsidiary. On February 19, 2014, the Venezuelan government established a new foreign exchange market mechanism (“SICAD 2”) and has indicated that this will be the market through which U.S. dollars will be obtained for the remittance of dividends. This market has significantly higher foreign exchange rates than those available through the other foreign exchange mechanisms. In the fourth quarter of fiscal 2014, we recorded a $62.2 million foreign exchange loss in the International segment operating profit resulting from the remeasurement of assets and liabilities of our Venezuelan subsidiary at the SICAD 2 rate of 50.0 bolivars per U.S. dollar. We have been able to access U.S. dollars through the SICAD 2 market. Our Venezuela operations represent less than 1 percent of our consolidated assets, liabilities, net sales, and segment operating profit. At May 25, 2014, we had $2.6 million of non-U.S. dollar cash balances in Venezuela.
EQUITY INSTRUMENTS
Equity price movements affect our compensation expense as certain investments made by our employees in our deferred compensation plan are revalued. We use equity swaps to manage this risk. As of May 25, 2014, the net notional amount of our equity swaps was $104.4 million. These swap contracts mature in fiscal 2015.

The net amount of pre-tax gains and losses in AOCI as of May 25, 2014, that we expect to be reclassified into net earnings within the next 12 months is $7.4 million of loss.
CREDIT-RISK-RELATED CONTINGENT FEATURES
Certain of our derivative instruments contain provisions that require us to maintain an investment grade credit rating on our debt from each of the major credit rating agencies. If our debt were to fall below investment grade, the counterparties to the derivative instruments could request full collateralization on derivative instruments in net liability positions. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a liability position on May 25, 2014, was $9.0 million. We have posted no collateral under these contracts. If the credit-risk-related contingent features underlying these agreements had been triggered on May 25, 2014, we would have been required to post $9.0 million of collateral to counterparties.
CONCENTRATIONS OF CREDIT AND COUNTERPARTY CREDIT RISK
During fiscal 2014, Wal-Mart Stores, Inc. and its affiliates (Wal-Mart) accounted for 21 percent of our consolidated net sales and 30 percent of our net sales in the U.S. Retail segment. No other customer accounted for 10 percent or more of our consolidated net sales. Wal-Mart also represented 7 percent of our net sales in the International segment and 7 percent of our net sales in the Convenience Stores and Foodservice segment. As of May 25, 2014, Wal-Mart accounted for 31 percent of our U.S. Retail receivables, 5 percent of our International receivables, and 9 percent of our Convenience Stores and Foodservice receivables. The five largest customers in our U.S. Retail segment accounted for 53 percent of its fiscal 2014 net sales, the five largest customers in our International segment accounted for 25 percent of its fiscal 2014 net sales, and the five largest customers in our Convenience Stores and Foodservice segment accounted for 42 percent of its fiscal 2014 net sales.
We enter into interest rate, foreign exchange, and certain commodity and equity derivatives, primarily with a diversified group of highly rated counterparties. We continually monitor our positions and the credit ratings of the counterparties involved and, by policy, limit the amount of credit exposure to any one party. These transactions may expose us to potential losses due to the risk of nonperformance by these counterparties; however, we have not incurred a material loss. We also enter into commodity futures transactions through various regulated exchanges.
The amount of loss due to the credit risk of the counterparties, should the counterparties fail to perform according to the terms of the contracts, is $5.9 million against which we do not hold collateral. Under the terms of our swap agreements, some of our transactions require collateral or other security to support financial instruments subject to threshold levels of exposure and counterparty credit risk. Collateral assets are either cash or U.S. Treasury instruments and are held in a trust account that we may access if the counterparty defaults.
We offer certain suppliers access to a third party service that allows them to view our scheduled payments online. The third party service also allows suppliers to finance advances on our scheduled payments at the sole discretion of the supplier and the third party. We have no economic interest in these financing arrangements and no direct relationship with the suppliers, the third party, or any financial institutions concerning this service. All of our accounts payable remain as obligations to our suppliers as stated in our supplier agreements. As of May 25, 2014, $285.5 million of our total accounts payable is payable to suppliers who utilize this third party service.

REDEEMABLE AND NONCONTROLLING INTERESTS [Abstract]	'
REDEEMABLE AND NONCONTROLLING INTERESTS	'
	NOTE 9. REDEEMABLE AND NONCONTROLLING INTERESTS
	Our principal redeemable and noncontrolling interests relate to our Yoplait S.A.S., Yoplait Marques S.A.S., Liberté Marques, S.a.r.l., and General Mills Cereals, LLC (GMC) subsidiaries. In addition, we have seven foreign subsidiaries that have noncontrolling interests totaling $5.8 million as of May 25, 2014.
	We have a 51 percent controlling interest in Yoplait S.A.S. and a 50 percent interest in Yoplait Marques S.A.S. Sodiaal holds the remaining interests in each of the entities. On the acquisition date in fiscal 2012, we recorded the $904.4 million fair value of Sodiaal's 49 percent euro-denominated interest in Yoplait S.A.S. as a redeemable interest on our Consolidated Balance Sheets. Sodiaal has the ability to put a limited portion of its redeemable interest to us at fair value once per year up to a maximum remaining term of 6 years. We adjust the value of the redeemable interest through additional paid-in capital on our Consolidated Balance Sheets quarterly to the redeemable interest's redemption value, which approximates its fair value. Yoplait S.A.S. pays dividends annually if it meets certain financial metrics set forth in its shareholders agreement. As of May 25, 2014, the redemption value of the euro-denominated redeemable interest was $984.1 million.
	In addition, a subsidiary of Yoplait S.A.S. has entered into an exclusive milk supply agreement for its European operations with Sodiaal at market-determined prices through July 1, 2021. Net purchases totaled $311.2 million for fiscal 2014 and $263.5 million for fiscal 2013.
	On the acquisition date in fiscal 2012, we recorded the $263.8 million fair value of Sodiaal's 50 percent euro-denominated interest in Yoplait Marques S.A.S. as a noncontrolling interest on our Consolidated Balance Sheets. Yoplait Marques S.A.S. earns a royalty stream through a licensing agreement with Yoplait S.A.S. for the rights to the Yoplait and related trademarks. Yoplait Marques S.A.S. pays dividends annually based on its available cash as of its fiscal year end.
	During the third quarter of fiscal 2014, we formed Liberté Marques, S.a.r.l. and sold a 50 percent euro-denominated interest in the entity to Sodiaal in exchange for $17.6 million. We recorded Sodiaal's 50 percent interest in the entity as a noncontrolling interest on our Consolidated Balance Sheets. Liberté Marques, S.a.r.l. earns a royalty stream through licensing agreements with certain Yoplait group companies for the rights to Liberté and related trademarks. Liberté Marques, S.a.r.l. pays dividends annually based on its available cash as of its fiscal year end.
	During fiscal 2014, we paid $71.9 million of dividends to Sodiaal under the terms of the Yoplait S.A.S. and Yoplait Marques S.A.S. shareholder agreements.
	During the first quarter of fiscal 2013, in conjunction with the consent of the Class A investor, we restructured GMC through the distribution of its manufacturing assets, stock, inventory, cash, and certain intellectual property to a wholly owned subsidiary. GMC retained the remaining intellectual property. Immediately following the restructuring, the Class A Interests of GMC were sold by the then current holder to another unrelated third-party investor.
	The holder of the GMC Class A Interests receives quarterly preferred distributions from available net income based on the application of a floating preferred return rate, currently equal to the sum of three-month LIBOR plus 110 basis points, to the holder's capital account balance established in the most recent mark-to-market valuation (currently $251.5 million). The preferred return rate is adjusted every three years through a negotiated agreement with the Class A Interest holder or through a remarketing auction.
	For financial reporting purposes, the assets, liabilities, results of operations, and cash flows of our non-wholly owned subsidiaries are included in our Consolidated Financial Statements. The third-party investor's share of the net earnings of these subsidiaries is reflected in net earnings attributable to redeemable and noncontrolling interests in the Consolidated Statements of Earnings.
	Our noncontrolling interests contain restrictive covenants. As of May 25, 2014, we were in compliance with all of these covenants.

	On June 28, 2010, our Board of Directors authorized the repurchase of up to 100 million shares of our common stock. The Board terminated this authorization on May 6, 2014, and authorized the repurchase of up to 100 million shares of our common stock. Purchases under the authorization can be made in the open market or in privately negotiated transactions, including the use of call options and other derivative instruments, Rule 10b5-1 trading plans, and accelerated repurchase programs. The authorization has no specified termination date.
	During fiscal 2014, we repurchased 35.6 million shares of common stock for an aggregate purchase price of $1,774.4 million. During fiscal 2013, we repurchased 24.2 million shares of common stock for an aggregate purchase price of $1,014.9 million. During fiscal 2012, we repurchased 8.3 million shares of common stock for an aggregate purchase price of $313.0 million.
	During the fourth quarter of fiscal 2013, we entered into an Accelerated Share Repurchase (ASR) agreement with an unrelated third party financial institution to repurchase an aggregate of $300.0 million of our outstanding common stock. Under the ASR agreement, we paid $300.0 million to the financial institution and received 5.5 million shares of common stock with a fair value of $270.0 million during the fourth quarter of 2013. We received an additional 0.6 million shares of common stock upon completion of the ASR agreement during the first quarter of fiscal 2014. As of May 26, 2013, we recorded this transaction as an increase in treasury stock of $270.0 million, and recorded the remaining $30.0 million as a decrease to additional paid-in capital on our Consolidated Balance Sheets. Upon completion of the ASR agreement in the first quarter of fiscal 2014, we reclassified the $30.0 million to treasury stock from additional paid-in capital on our Consolidated Balance Sheets.

STOCK PLANS [Abstract]	'
STOCK PLANS	'
	NOTE 11. STOCK PLANS
	We use broad-based stock plans to help ensure that management's interests are aligned with those of our stockholders. As of May 25, 2014, a total of 30.8 million shares were available for grant in the form of stock options, restricted stock, restricted stock units, and shares of unrestricted stock under the 2011 Stock Compensation Plan (2011 Plan) and the 2011 Compensation Plan for Non-Employee Directors. The 2011 Plan also provides for the issuance of cash-settled share-based units, stock appreciation rights, and performance awards. Stock-based awards now outstanding include some granted under the 2001, 2003, 2005, 2006, 2007, and 2009 stock plans and the Executive Incentive Plan, under which no further awards may be granted. The stock plans provide for accelerated vesting of awards upon retirement, termination, or death of eligible employees and directors.
	Stock Options
	The estimated fair values of stock options granted and the assumptions used for the Black-Scholes option-pricing model were as follows:
			Fiscal Year
			2014		2013		2012
	Estimated fair values of stock options granted		$6.03		$3.65		$5.88
	Assumptions:
	Risk-free interest rate		2.60%		1.60%		2.90%
	Expected term		9.0years		9.0years		8.5years
	Expected volatility		17.40%		17.30%		17.60%
	Dividend yield		3.10%		3.50%		3.30%
	The valuation of stock options is a significant accounting estimate that requires us to use judgments and assumptions that are likely to have a material impact on our financial statements. Annually, we make predictive assumptions regarding future stock price volatility, employee exercise behavior, dividend yield, and the forfeiture rate.
	We estimate the fair value of each option on the grant date using a Black-Scholes option-pricing model, which requires us to make predictive assumptions regarding future stock price volatility, employee exercise behavior, and dividend yield. We estimate our future stock price volatility using the historical volatility over the expected term of the option, excluding time periods of volatility we believe a marketplace participant would exclude in estimating our stock price volatility. We also have considered, but did not use, implied volatility in our estimate, because trading activity in options on our stock, especially those with tenors of greater than 6 months, is insufficient to provide a reliable measure of expected volatility.
	Our expected term represents the period of time that options granted are expected to be outstanding based on historical data to estimate option exercises and employee terminations within the valuation model. Separate groups of employees have similar historical exercise behavior and therefore were aggregated into a single pool for valuation purposes. The weighted-average expected term for all employee groups is presented in the table above. The risk-free interest rate for periods during the expected term of the options is based on the U.S. Treasury zero-coupon yield curve in effect at the time of grant.
	Any corporate income tax benefit realized upon exercise or vesting of an award in excess of that previously recognized in earnings (referred to as a windfall tax benefit) is presented in the Consolidated Statements of Cash Flows as a financing cash flow.
	Realized windfall tax benefits are credited to additional paid-in capital within the Consolidated Balance Sheets. Realized shortfall tax benefits (amounts which are less than that previously recognized in earnings) are first offset against the cumulative balance of windfall tax benefits, if any, and then charged directly to income tax expense, potentially resulting in volatility in our consolidated effective income tax rate. We calculated a cumulative memo balance of windfall tax benefits for the purpose of accounting for future shortfall tax benefits.
	Options may be priced at 100 percent or more of the fair market value on the date of grant, and generally vest four years after the date of grant. Options generally expire within 10 years and one month after the date of grant.

	Restricted Stock, Restricted Stock Units, and Cash-Settled Share-Based Units
	Stock and units settled in stock subject to a restricted period and a purchase price, if any (as determined by the Compensation Committee of the Board of Directors), may be granted to key employees under the 2011 Plan. Restricted stock and restricted stock units generally vest and become unrestricted four years after the date of grant. Participants are entitled to dividends on such awarded shares and units, but only receive those amounts if the shares or units vest. The sale or transfer of these shares and units is restricted during the vesting period. Participants holding restricted stock, but not restricted stock units, are entitled to vote on matters submitted to holders of common stock for a vote.

RETIREMENT BENEFITS AND POSTEMPLOYMENT BENEFITS [Abstract]	'
RETIREMENT BENEFITS AND POSTEMPLOYMENT BENEFITS	'
	NOTE 13. RETIREMENT BENEFITS AND POSTEMPLOYMENT BENEFITS
	Defined Benefit Pension Plans
	We have defined benefit pension plans covering most employees in the United States, Canada, France, and the United Kingdom. Benefits for salaried employees are based on length of service and final average compensation. Benefits for hourly employees include various monthly amounts for each year of credited service. Our funding policy is consistent with the requirements of applicable laws. We made no voluntary contributions to our principal U.S. plans in fiscal 2014 and made a $200.0 million voluntary contribution in each of fiscal 2013 and fiscal 2012. We do not expect to be required to make any contributions in fiscal 2015. Our principal domestic retirement plan covering salaried employees has a provision that any excess pension assets would be allocated to active participants if the plan is terminated within five years of a change in control. In fiscal 2012, we announced changes to our U.S. defined benefit pension plans. All new salaried employees hired on or after June 1, 2013 are eligible for a new retirement program that does not include a defined benefit pension plan. Current salaried employees remain in the existing defined benefit pension plan with adjustments to benefits.
	Other Postretirement Benefit Plans
	We also sponsor plans that provide health care benefits to the majority of our retirees in the United States, Canada, and Brazil. The United States salaried health care benefit plan is contributory, with retiree contributions based on years of service. We make decisions to fund related trusts for certain employees and retirees on an annual basis. We made $24.0 million in voluntary contributions to these plans in fiscal 2014. We did not make voluntary contributions to these plans in fiscal 2013.
	Health Care Cost Trend Rates
	Assumed health care cost trends are as follows:
		Fiscal Year
		2014		2013
	Health care cost trend rate for next year	6.5% and 7.3%		8.00%
	Rate to which the cost trend rate is assumed to decline (ultimate rate)	5.00%		5.20%
	Year that the rate reaches the ultimate trend rate	2025		2019
	We review our health care cost trend rates annually. Our review is based on data we collect about our health care claims experience and information provided by our actuaries. This information includes recent plan experience, plan design, overall industry experience and projections, and assumptions used by other similar organizations. Our initial health care cost trend rate is adjusted as necessary to remain consistent with this review, recent experiences, and short-term expectations. Our initial health care cost trend rate assumption is 7.3 percent for retirees age 65 and over and 6.5 percent for retirees under age 65 at the end of fiscal 2014. Rates are graded down annually until the ultimate trend rate of 5.0 percent is reached in 2025 for all retirees. The trend rates are applicable for calculations only if the retirees' benefits increase as a result of health care inflation. The ultimate trend rate is adjusted annually, as necessary, to approximate the current economic view on the rate of long-term inflation plus an appropriate health care cost premium. Assumed trend rates for health care costs have an important effect on the amounts reported for the other postretirement benefit plans.
	A one percentage point change in the health care cost trend rate would have the following effects:
	In Millions		One Percentage Point Increase		One Percentage Point Decrease
	Effect on the aggregate of the service and interest cost components in fiscal 2015	$	4.7	$	-3.9
	Effect on the other postretirement accumulated benefit obligation as of May 25, 2014		82.7		-73.2
	The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, the Act) was signed into law in March 2010. The Act codifies health care reforms with staggered effective dates from 2010 to 2018. Estimates of the future impacts of several of the Act's provisions are incorporated into our postretirement benefit liability.
	Postemployment Benefit Plans
	Under certain circumstances, we also provide accruable benefits to former or inactive employees in the United States, Canada, and Mexico, and members of our Board of Directors, including severance and certain other benefits payable upon death. We recognize an obligation for any of these benefits that vest or accumulate with service. Postemployment benefits that do not vest or accumulate with service (such as severance based solely on annual pay rather than years of service) are charged to expense when incurred. Our postemployment benefit plans are unfunded.
	We use our fiscal year end as the measurement date for our defined benefit pension and other postretirement benefit plans.

Discount Rates
Our discount rate assumptions are determined annually as of the last day of our fiscal year for our defined benefit pension, other postretirement, and postemployment benefit plan obligations. We also use the same discount rates to determine defined benefit pension, other postretirement, and postemployment benefit plan income and expense for the following fiscal year. We work with our outside actuaries to determine the timing and amount of expected future cash outflows to plan participants and, using the Aa Above Median corporate bond yield, to develop a forward interest rate curve, including a margin to that index based on our credit risk. This forward interest rate curve is applied to our expected future cash outflows to determine our discount rate assumptions.

(a)       Primarily publicly traded common stock and private equity partnerships for purposes of total return and to maintain equity exposure consistent with policy allocations. Investments include: United States and international equity securities, mutual funds, and equity futures valued at closing prices from national exchanges; and commingled funds, privately held securities, and private equity partnerships valued at unit values or net asset values provided by the investment managers, which are based on the fair value of the underlying investments. Various methods are used to determine fair values and may include the cost of the investment, most recent financing, and expected cash flows. For some of these investments, realization of the estimated fair value is dependent upon transactions between willing sellers and buyers.
(b)       Primarily government and corporate debt securities for purposes of total return and managing fixed income exposure to policy allocations. Investments include: fixed income securities and bond futures generally valued at closing prices from national exchanges, fixed income pricing models, and independent financial analysts; and fixed income commingled funds valued at unit values provided by the investment managers, which are based on the fair value of the underlying investments.
(c)        Publicly traded common stock and limited partnerships in the energy and real estate sectors for purposes of total return. Investments include: energy and real estate securities generally valued at closing prices from national exchanges; and commingled funds, private securities, and limited partnerships valued at unit values or net asset values provided by the investment managers, which are generally based on the fair value of the underlying investments.
(d)        Global balanced fund of equity, fixed income, and real estate securities for purposes of meeting Canadian pension plan asset allocation policies, and insurance and annuity contracts to provide a stable stream of income for retirees and to fund postretirement medical benefits. Fair values are derived from unit values provided by the investment managers, which are generally based on the fair value of the underlying investments and contract fair values from the providers.

The net change in level 3 assets attributable to unrealized gains at May 25, 2014, was $ 85.3 million for our pension plan assets, and $2.6 million for our postretirement benefit plan assets.
Expected Rate of Return on Plan Assets
Our expected rate of return on plan assets is determined by our asset allocation, our historical long-term investment performance, our estimate of future long-term returns by asset class (using input from our actuaries, investment services, and investment managers), and long-term inflation assumptions. We review this assumption annually for each plan, however, our annual investment performance for one particular year does not, by itself, significantly influence our evaluation.
Weighted-average asset allocations for the past two fiscal years for our defined benefit pension and other postretirement benefit plans are as follows:
	Defined Benefit Pension Plans					Other Postretirement Benefit Plans
	Fiscal Year					Fiscal Year
	2014		2013			2014		2013
Asset category:
United States equities	25.5	%	29.5	%		38.4	%	39.4	%
International equities	13.9		17.3			24		21.6
Private equities	10.3		11.2			4.1		4.7
Fixed income	35.5		27.5			26.3		28.9
Real assets	14.8		14.5			7.2		5.4
Total	100	%	100	%		100	%	100	%
The investment objective for our defined benefit pension and other postretirement benefit plans is to secure the benefit obligations to participants at a reasonable cost to us. Our goal is to optimize the long-term return on plan assets at a moderate level of risk. The defined benefit pension plan and other postretirement benefit plan portfolios are broadly diversified across asset classes. Within asset classes, the portfolios are further diversified across investment styles and investment organizations. For the defined benefit pension plans, the long-term investment policy allocation is: 25 percent to equities in the United States; 15 percent to international equities; 10 percent to private equities; 35 percent to fixed income; and 15 percent to real assets (real estate, energy, and timber). For other postretirement benefit plans, the long-term investment policy allocations are: 30 percent to equities in the United States; 20 percent to international equities; 10 percent to private equities; 30 percent to fixed income; and 10 percent to real assets (real estate, energy, and timber). The actual allocations to these asset classes may vary tactically around the long-term policy allocations based on relative market valuations.
Contributions and Future Benefit Payments
We do not expect to be required to make contributions to our defined benefit pension, other postretirement benefit, and postemployment benefit plans in fiscal 2015. Actual fiscal 2015 contributions could exceed our current projections, as influenced by our decision to undertake discretionary funding of our benefit trusts and future changes in regulatory requirements. Estimated benefit payments, which reflect expected future service, as appropriate, are expected to be paid from fiscal 2015 to 2024 as follows:
In Millions			Defined Benefit Pension Plans			Other Postretirement Benefit Plans Gross Payments			Medicare Subsidy Receipts			Postemployment Benefit Plans
2015		$	244.6		$	60.3		$	4.7		$	21
2016			253.8			62.8			5.2			19.3
2017			263.4			63.7			5.5			17.9
2018			273.5			64.2			6			16.8
2019			284.3			66.5			6.4			16
2020-2024			1,596.60			359.6			25.5			70.5
Defined Contribution Plans
The General Mills Savings Plan is a defined contribution plan that covers domestic salaried, hourly, nonunion, and certain union employees. This plan is a 401(k) savings plan that includes a number of investment funds, including a Company stock fund and an Employee Stock Ownership Plan (ESOP). We sponsor another money purchase plan for certain domestic hourly employees with net assets of $20.6 million as of May 25, 2014, and $19.4 million as of May 26, 2013. We also sponsor defined contribution plans in many of our foreign locations. Our total recognized expense related to defined contribution plans was $44.8 million in fiscal 2014, $46.0 million in fiscal 2013, and $41.8 million in fiscal 2012.
We match a percentage of employee contributions to the General Mills Savings Plan. The Company match is directed to investment options of the participant's choosing. The number of shares of our common stock allocated to participants in the ESOP was 8.4 million as of May 25, 2014, and 9.1 million as of May 26, 2013. The ESOP's only assets are our common stock and temporary cash balances.
The Company stock fund and the ESOP held $708.2 million and $691.9 million of Company common stock as of May 25, 2014, and May 26, 2013.

	We have established a valuation allowance against certain of the categories of deferred tax assets described above as current evidence does not suggest we will realize sufficient taxable income of the appropriate character (e.g., ordinary income versus capital gain income) within the carryforward period to allow us to realize these deferred tax benefits.
	Of the total valuation allowance of $221.6 million, $161.2 million relates to a deferred tax asset for losses recorded as part of the Pillsbury acquisition and $57.2 million relates to various state and foreign loss carryforwards. We have approximately $74 million of U.S. foreign tax credit carryforwards for which no valuation allowance has been recorded. As of May 25, 2014, we believe it is more-likely-than-not that the remainder of our deferred tax assets are realizable.
	The carryforward periods on our foreign loss carryforwards are as follows:  $42.4 million do not expire; $7.9 million expire in fiscal 2015 and 2016; and $25.2 million expire in fiscal 2017 and beyond.
	We have not recognized a deferred tax liability for unremitted earnings of approximately $2.8 billion from our foreign operations because our subsidiaries have invested or will invest the undistributed earnings indefinitely, or the earnings will be remitted in a tax-neutral transaction. It is not practicable for us to determine the amount of unrecognized deferred tax liabilities on these indefinitely reinvested earnings. Deferred taxes are recorded for earnings of our foreign operations when we determine that such earnings are no longer indefinitely reinvested.
	In fiscal 2010, we recorded a non-cash income tax charge and decrease to our deferred tax assets of $35.0 million related to a reduction of the tax deductibility of retiree health cost to the extent of any Medicare Part D subsidy received beginning in fiscal 2013 under the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010. During fiscal 2013, we took certain actions to restore part of the tax benefits associated with Medicare Part D subsidies and recorded a $33.7 million discrete decrease to income tax expense and an increase to our deferred tax assets.
	During the first quarter of fiscal 2013, in conjunction with the consent of the Class A investor, we restructured GMC through the distribution of its manufacturing assets, stock, inventory, cash, and certain intellectual property to a wholly owned subsidiary. GMC retained the remaining intellectual property. Immediately following this restructuring, the Class A Interests were sold by the then current holder to another unrelated third party investor. As a result of these transactions, we recorded a $63.3 million decrease to deferred income tax liabilities related to the tax basis of the investment in GMC and certain distributed assets, with a corresponding discrete non-cash reduction to income taxes in fiscal 2013.
	We are subject to federal income taxes in the United States as well as various state, local, and foreign jurisdictions. A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, we believe that our liabilities for income taxes reflect the most likely outcome. We adjust these liabilities, as well as the related interest, in light of changing facts and circumstances. Settlement of any particular position would usually require the use of cash.
The number of years with open tax audits varies depending on the tax jurisdiction. Our major taxing jurisdictions include the United States (federal and state) and Canada. Various tax examinations by United States state taxing authorities could be conducted for any open tax year, which vary by jurisdiction, but are generally from 3 to 5 years.
The Internal Revenue Service (IRS) is currently auditing our federal tax returns for the fiscal 2011 and 2012 tax years. Several state examinations are also in progress.
During fiscal 2013, the IRS concluded its field examination of our 2009 and 2010 tax years and proposed adjustments related to the timing for deducting accrued bonus expenses. The audit closure and related proposed adjustments did not have a material impact on our results of operations or financial position. The accrued bonus issue is currently under review by the IRS Appeals Division. We expect to make a one-time cash payment of approximately $6 million to settle this issue in fiscal 2015. As of May 25, 2014, we have effectively settled all issues with the IRS for fiscal years 2008 and prior.
During fiscal 2014, the Canadian Revenue Agency (CRA) completed its review of our Canadian income tax returns for fiscal years 2009 through 2011. Assessments related to a prior CRA audit for fiscal years 2004 and 2005 were resolved by the U.S. and Canadian competent authority divisions during fiscal 2014. As of May 25, 2014, all issues associated with fiscal years 2004 and 2005 and 2009 through 2011 have been resolved. The resolution did not have a material impact on our results of operations or financial position.
We apply a more-likely-than-not threshold to the recognition and derecognition of uncertain tax positions. Accordingly, we recognize the amount of tax benefit that has a greater than 50 percent likelihood of being ultimately realized upon settlement. Future changes in judgment related to the expected ultimate resolution of uncertain tax positions will affect earnings in the quarter of such change.
The following table sets forth changes in our total gross unrecognized tax benefit liabilities, excluding accrued interest, for fiscal 2014. Approximately $87 million of this total represents the amount that, if recognized, would affect our effective income tax rate in future periods. This amount differs from the gross unrecognized tax benefits presented in the table because certain of the liabilities below would impact deferred taxes if recognized. We also would record a decrease in U.S. federal income taxes upon recognition of the state tax benefits included therein.

As of May 25, 2014, we expect to pay approximately $20 million of unrecognized tax benefit liabilities and accrued interest within the next 12 months. We are not able to reasonably estimate the timing of future cash flows beyond 12 months due to uncertainties in the timing of tax audit outcomes. The remaining amount of our unrecognized tax liability was classified in other liabilities.
We report accrued interest and penalties related to unrecognized tax benefit liabilities in income tax expense. For fiscal 2014, we recognized a net benefit of $4.6 million of tax-related net interest and penalties, and had $42.0 million of accrued interest and penalties as of May 25, 2014. For fiscal 2013, we recognized a net benefit of $3.0 million of tax-related net interest and penalties, and had $53.1 million of accrued interest and penalties as of May 26, 2013.

We have three operating segments by type of customer and geographic region as follows: U.S. Retail, 59.2 percent of our fiscal 2014 consolidated net sales; International, 30.1 percent of our fiscal 2014 consolidated net sales; and Convenience Stores and Foodservice, 10.7 percent of our fiscal 2014 consolidated net sales.
	Our U.S. Retail segment reflects business with a wide variety of grocery stores, mass merchandisers, membership stores, natural food chains, and drug, dollar and discount chains operating throughout the United States. Our product categories in this business segment include ready-to-eat cereals, refrigerated yogurt, ready-to-serve soup, dry dinners, shelf stable and frozen vegetables, refrigerated and frozen dough products, dessert and baking mixes, frozen pizza and pizza snacks, grain, fruit and savory snacks, and a wide variety of organic products including granola bars, cereal, and soup.
	Our International segment consists of retail and foodservice businesses outside of the United States. In Canada, our product categories include ready-to-eat cereals, shelf stable and frozen vegetables, dry dinners, refrigerated and frozen dough products, dessert and baking mixes, frozen pizza snacks, refrigerated yogurt, and grain and fruit snacks. In markets outside North America, our product categories include super-premium ice cream and frozen desserts, refrigerated yogurt, snacks, shelf stable and frozen vegetables, refrigerated and frozen dough products, and dry dinners. Our International segment also includes products manufactured in the United States for export, mainly to Caribbean and Latin American markets, as well as products we manufacture for sale to our international joint ventures. Revenues from export activities and franchise fees are reported in the region or country where the end customer is located.
	In the first quarter of fiscal 2014, we changed the name of our Bakeries and Foodservice operating segment to Convenience Stores and Foodservice. The businesses in this segment were unchanged. Our major product categories are ready-to-eat cereals, snacks, refrigerated yogurt, unbaked and fully baked frozen dough products, baking mixes, and flour. Many products we sell are branded to the consumer and nearly all are branded to our customers. We sell to distributors and operators in many customer channels including foodservice, convenience stores, vending, and supermarket bakeries. Substantially all of this segment's operations are located in the United States.
	Operating profit for these segments excludes unallocated corporate items and restructuring, impairment, and other exit costs. Unallocated corporate items include corporate overhead expenses, variances to planned domestic employee benefits and incentives, contributions to the General Mills Foundation, and other items that are not part of our measurement of segment operating performance. These include gains and losses arising from the revaluation of certain grain inventories and gains and losses from mark-to-market valuation of certain commodity positions until passed back to our operating segments. These items affecting operating profit are centrally managed at the corporate level and are excluded from the measure of segment profitability reviewed by executive management. Under our supply chain organization, our manufacturing, warehouse, and distribution activities are substantially integrated across our operations in order to maximize efficiency and productivity. As a result, fixed assets and depreciation and amortization expenses are neither maintained nor available by operating segment.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	25-May-14
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]	'
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	We consider all investments purchased with an original maturity of three months or less to be cash equivalents.
Inventories	'
	Inventories
	All inventories in the United States other than grain are valued at the lower of cost, using the last-in, first-out (LIFO) method, or market. Grain inventories and all related cash contracts and derivatives are valued at market with all net changes in value recorded in earnings currently.
	Inventories outside of the United States are generally valued at the lower of cost, using the first-in, first-out (FIFO) method, or market.
	Shipping costs associated with the distribution of finished product to our customers are recorded as cost of sales, and are recognized when the related finished product is shipped to and accepted by the customer.
Land, Buildings, Equipment, and Depreciation	'
	Land, Buildings, Equipment, and Depreciation
	Land is recorded at historical cost. Buildings and equipment, including capitalized interest and internal engineering costs, are recorded at cost and depreciated over estimated useful lives, primarily using the straight-line method. Ordinary maintenance and repairs are charged to cost of sales. Buildings are usually depreciated over 40 to 50 years, and equipment, furniture, and software are usually depreciated over 3 to 10 years. Fully depreciated assets are retained in buildings and equipment until disposal. When an item is sold or retired, the accounts are relieved of its cost and related accumulated depreciation and the resulting gains and losses, if any, are recognized in earnings. As of May 25, 2014, assets held for sale were insignificant.
	Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset (or asset group) may not be recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows from the operation and disposition of the asset group are less than the carrying amount of the asset group. Asset groups have identifiable cash flows and are largely independent of other asset groups. Measurement of an impairment loss would be based on the excess of the carrying amount of the asset group over its fair value. Fair value is measured using a discounted cash flow model or independent appraisals, as appropriate.
Goodwill and Other Intangible Assets	'
	Goodwill and Other Intangible Assets
	Goodwill is not subject to amortization and is tested for impairment annually and whenever events or changes in circumstances indicate that impairment may have occurred. Impairment testing is performed for each of our reporting units. We compare the carrying value of a reporting unit, including goodwill, to the fair value of the unit. Carrying value is based on the assets and liabilities associated with the operations of that reporting unit, which often requires allocation of shared or corporate items among reporting units. If the carrying amount of a reporting unit exceeds its fair value, we revalue all assets and liabilities of the reporting unit, excluding goodwill, to determine if the fair value of the net assets is greater than the net assets including goodwill. If the fair value of the net assets is less than the carrying amount of net assets including goodwill, impairment has occurred. Our estimates of fair value are determined based on a discounted cash flow model. Growth rates for sales and profits are determined using inputs from our long-range planning process. We also make estimates of discount rates, perpetuity growth assumptions, market comparables, and other factors.
	We evaluate the useful lives of our other intangible assets, mainly brands, to determine if they are finite or indefinite-lived. Reaching a determination on useful life requires significant judgments and assumptions regarding the future effects of obsolescence, demand, competition, other economic factors (such as the stability of the industry, known technological advances, legislative action that results in an uncertain or changing regulatory environment, and expected changes in distribution channels), the level of required maintenance expenditures, and the expected lives of other related groups of assets. Intangible assets that are deemed to have definite lives are amortized on a straight-line basis, over their useful lives, generally ranging from 4 to 30 years.
	Our indefinite-lived intangible assets, mainly intangible assets primarily associated with the Pillsbury, Totino's, Progresso, Green Giant, Yoplait, Old El Paso, Yoki, and Häagen-Dazs brands, are also tested for impairment annually and whenever events or changes in circumstances indicate that their carrying value may not be recoverable. We performed our fiscal 2014 assessment of our brand intangibles as of November 25, 2013. Our estimate of the fair value of the brands was based on a discounted cash flow model using inputs which included projected revenues from our long-range plan, assumed royalty rates that could be payable if we did not own the brands, and a discount rate.
	Our finite-lived intangible assets, primarily acquired franchise agreements and customer relationships, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows from the operation and disposition of the asset are less than the carrying amount of the asset. Assets generally have identifiable cash flows and are largely independent of other assets. Measurement of an impairment loss would be based on the excess of the carrying amount of the asset over its fair value. Fair value is measured using a discounted cash flow model or other similar valuation model, as appropriate.
Investments in Joint Ventures and Redeemable Interest	'
	Investments in Joint Ventures
	Our investments in companies over which we have the ability to exercise significant influence are stated at cost plus our share of undistributed earnings or losses. We receive royalty income from certain joint ventures, incur various expenses (primarily research and development), and record the tax impact of certain joint venture operations that are structured as partnerships. In addition, we make advances to our joint ventures in the form of loans or capital investments. We also sell certain raw materials, semi-finished goods, and finished goods to the joint ventures, generally at market prices.
	In addition, we assess our investments in our joint ventures if we have reason to believe an impairment may have occurred including, but not limited to, ongoing operating losses, projected decreases in earnings, increases in the weighted average cost of capital or significant business disruptions. The significant assumptions used to estimate fair value include revenue growth and profitability, royalty rates, capital spending, depreciation and taxes, foreign currency exchange rates, and a discount rate. By their nature, these projections and assumptions are uncertain. If we were to determine the current fair value of our investment was less than the carrying value of the investment, then we would assess if the shortfall was of a temporary or permanent nature and write down the investment to its fair value if we concluded the impairment is other than temporary.
	Redeemable Interest
	We have a 51 percent controlling interest in Yoplait S.A.S., a consolidated entity. Sodiaal International (Sodiaal) holds the remaining 49 percent interest in Yoplait S.A.S. Sodiaal has the ability to put a limited portion of its redeemable interest to us at fair value once per year up to a maximum remaining term of 6 years. This put option requires us to classify Sodiaal's interest as a redeemable interest outside of equity on our Consolidated Balance Sheets for as long as the put is exercisable by Sodiaal. When the put is no longer exercisable, the redeemable interest will be reclassified to noncontrolling interests on our Consolidated Balance Sheets. We adjust the value of the redeemable interest through additional paid-in capital on our Consolidated Balance Sheets quarterly to the redeemable interest's redemption value, which approximates its fair value. During the third quarter of fiscal 2014, we adjusted the redeemable interest's redemption value based on a discounted cash flow model. The significant assumptions used to estimate the redemption value include projected revenue growth and profitability from our long-range plan, capital spending, depreciation, taxes, foreign currency rates, and a discount rate.
Revenue Recognition	'
	Revenue Recognition
	We recognize sales revenue when the shipment is accepted by our customer. Sales include shipping and handling charges billed to the customer and are reported net of consumer coupon redemption, trade promotion and other costs, including estimated allowances for returns, unsalable product, and prompt pay discounts. Sales, use, value-added, and other excise taxes are not recognized in revenue. Coupons are recorded when distributed, based on estimated redemption rates. Trade promotions are recorded based on estimated participation and performance levels for offered programs at the time of sale. We generally do not allow a right of return. However, on a limited case-by-case basis with prior approval, we may allow customers to return product. In limited circumstances, product returned in saleable condition is resold to other customers or outlets. Receivables from customers generally do not bear interest. Terms and collection patterns vary around the world and by channel. The allowance for doubtful accounts represents our estimate of probable non-payments and credit losses in our existing receivables, as determined based on a review of past due balances and other specific account data. Account balances are written off against the allowance when we deem the amount is uncollectible.
Environmental	'
	Environmental
	Environmental costs relating to existing conditions caused by past operations that do not contribute to current or future revenues are expensed. Liabilities for anticipated remediation costs are recorded on an undiscounted basis when they are probable and reasonably estimable, generally no later than the completion of feasibility studies or our commitment to a plan of action.
Advertising Production Costs	'
	Advertising Production Costs
	We expense the production costs of advertising the first time that the advertising takes place.
Research and Development	'
	Research and Development
	All expenditures for research and development (R&D) are charged against earnings in the year incurred. R&D includes expenditures for new product and manufacturing process innovation, and the annual expenditures are comprised primarily of internal salaries, wages, consulting, and other supplies attributable to time spent on R&D activities. Other costs include depreciation and maintenance of research facilities, including assets at facilities that are engaged in pilot plant activities.
Foreign Currency Translation	'
	Foreign Currency Translation
	For all significant foreign operations, the functional currency is the local currency. Assets and liabilities of these operations are translated at the period-end exchange rates. Income statement accounts are translated using the average exchange rates prevailing during the year. Translation adjustments are reflected within accumulated other comprehensive loss (AOCI) in stockholders' equity. Gains and losses from foreign currency transactions are included in net earnings for the period, except for gains and losses on investments in subsidiaries for which settlement is not planned for the foreseeable future and foreign exchange gains and losses on instruments designated as net investment hedges. These gains and losses are recorded in AOCI.
Derivative Instruments	'
	Derivative Instruments
	All derivatives are recognized on the Consolidated Balance Sheets at fair value based on quoted market prices or our estimate of their fair value, and are recorded in either current or noncurrent assets or liabilities based on their maturity. Changes in the fair values of derivatives are recorded in net earnings or other comprehensive income, based on whether the instrument is designated and effective as a hedge transaction and, if so, the type of hedge transaction. Gains or losses on derivative instruments reported in AOCI are reclassified to earnings in the period the hedged item affects earnings. If the underlying hedged transaction ceases to exist, any associated amounts reported in AOCI are reclassified to earnings at that time. Any ineffectiveness is recognized in earnings in the current period.
Stock-based Compensation	'
	Stock-based Compensation
	We generally measure compensation expense for grants of restricted stock units using the value of a share of our stock on the date of grant. We estimate the value of stock option grants using a Black-Scholes valuation model. Stock compensation is recognized straight line over the vesting period. Our stock compensation expense is recorded in selling, general and administrative (SG&A) expenses and cost of sales in the Consolidated Statements of Earnings and allocated to each reportable segment in our segment results.
	Certain equity-based compensation plans contain provisions that accelerate vesting of awards upon retirement, termination, or death of eligible employees and directors. We consider a stock-based award to be vested when the employee's retention of the award is no longer contingent on providing subsequent service. Accordingly, the related compensation cost is recognized immediately for awards granted to retirement-eligible individuals or over the period from the grant date to the date retirement eligibility is achieved, if less than the stated vesting period.
	We report the benefits of tax deductions in excess of recognized compensation cost as a financing cash flow, thereby reducing net operating cash flows and increasing net financing cash flows.
Defined Benefit Pension, Other Postretirement Benefit, and Postemployment Benefit Plans	'
	Defined Benefit Pension, Other Postretirement Benefit, and Postemployment Benefit Plans
	We sponsor several domestic and foreign defined benefit plans to provide pension, health care, and other welfare benefits to retired employees. Under certain circumstances, we also provide accruable benefits to former or inactive employees in the United States and Canada and members of our Board of Directors, including severance and certain other benefits payable upon death. We recognize an obligation for any of these benefits that vest or accumulate with service. Postemployment benefits that do not vest or accumulate with service (such as severance based solely on annual pay rather than years of service) are charged to expense when incurred. Our postemployment benefit plans are unfunded.
	We recognize the underfunded or overfunded status of a defined benefit pension plan as an asset or liability and recognize changes in the funded status in the year in which the changes occur through AOCI.

	Preparing our Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates include our accounting for promotional expenditures, valuation of long-lived assets, intangible assets, redeemable interest, stock-based compensation, income taxes, and defined benefit pension, postretirement and postemployment benefits. Actual results could differ from our estimates.

	(a)       Primarily publicly traded common stock and private equity partnerships for purposes of total return and to maintain equity exposure consistent with policy allocations. Investments include: United States and international equity securities, mutual funds, and equity futures valued at closing prices from national exchanges; and commingled funds, privately held securities, and private equity partnerships valued at unit values or net asset values provided by the investment managers, which are based on the fair value of the underlying investments. Various methods are used to determine fair values and may include the cost of the investment, most recent financing, and expected cash flows. For some of these investments, realization of the estimated fair value is dependent upon transactions between willing sellers and buyers.
	(b)       Primarily government and corporate debt securities for purposes of total return and managing fixed income exposure to policy allocations. Investments include: fixed income securities and bond futures generally valued at closing prices from national exchanges, fixed income pricing models, and independent financial analysts; and fixed income commingled funds valued at unit values provided by the investment managers, which are based on the fair value of the underlying investments.
	(c)        Publicly traded common stock and limited partnerships in the energy and real estate sectors for purposes of total return.

Number of shares available for grant under stock compensation plan	30.8	'	'
Share-based Compensation Arrangement by Share-based Payment Award, Fair Value Assumptions Method Used	'We estimate the fair value of each option on the grant date using a Black-Scholes option-pricing model, which requires us to make predictive assumptions regarding future stock price volatility, employee exercise behavior, and dividend yield. We estimate our future stock price volatility using the historical volatility over the expected term of the option, excluding time periods of volatility we believe a marketplace participant would exclude in estimating our stock price volatility. We also have considered, but did not use, implied volatility in our estimate, because trading activity in options on our stock, especially those with tenors of greater than 6 months, is insufficient to provide a reliable measure of expected volatility. Our expected term represents the period of time that options granted are expected to be outstanding based on historical data to estimate option exercises and employee terminations within the valuation model. Separate groups of employees have similar historical exercise behavior and therefore were aggregated into a single pool for valuation purposes. The weighted-average expected term for all employee groups is presented in the table above. The risk-free interest rate for periods during the expected term of the options is based on the U.S. Treasury zero-coupon yield curve in effect at the time of grant.	'	'
