Background [Abstract]
Background	( 1 ) Background The accompanying Consolidated Financial Statements of General Mills, Inc. (we, us, our, General Mills, or the Company) have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and with the rules and regulations for reporting on Form 10-Q. Accordingly, they do not include certain information and disclosures required for comprehensive financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included and are of a normal recurring nature, including the elimination of all intercompany t ransactions and any noncontrolling and redeemable interests’ share of those transactions. Operating results for the quarter ended February 25, 2018 are not necessarily indicative of the results that may be expected for the fiscal year ending May 27, 2018 . These state ments should be read in conjunction with the Consolidated Financial Statements and footnotes included in our Annual Report on Form 10-K for the fiscal year ended May 28, 2017 . The accounting policies used in preparing these Consolidated Financial Statements ar e the same as those described in Note 2 to the Consolidated Financial Statements in that Form 10-K with the exception of the new accounting requirements adopted in the first quarter of fiscal 2018 for stock-based payments and goodwill impairment testing an d new accounting requirements adopted in the third quarter of fiscal 2018 for the reclassification of certain income tax effects from accumulated other comprehensive income to retained earnings. See Note 15 and Note 1 7 to the Consolidated Financial Statements in Part I, Item 1 of this report for additional information. Certain terms used throughout this report are defined in the “Glossary” section below. In the nine -month period ended February 25, 2018 , we recorded an adjustment related to a prior year which increased incom e tax expense and total liabilities by $40.5 million in our Consolidated Financial Statements. We determined the adjustment to be immaterial to our estimated Consolidated Statements of Earnings for the fiscal year ended May 27, 2018.

Acquisition and Divestiture [Abstract]
Acquisition and Divestiture	( 2 ) Acquisition and Divestiture During the third quarter of fiscal 2018, we entered into a definitive agreement and plan of merger with Blue Buffalo Pet Products, Inc. (“Blue Buffalo”), a publicly held pet food company, pursuant to which a subsidiary of General Mills will merge into Blue Buffalo, with Blue Buffalo surviving the merger as a wholly owned subsidiary of General Mills. Equity holders of Blue Buffalo will receive $40.00 per share in cash, representing an enter prise value of approximately $8.0 billion in addition to the assumption of approximately $39 4 million of outstanding debt which will be repaid upon transaction close. We expect to finance the transaction with a combination of debt, cash on hand and approx imately $1 .0 billion in equity. The transaction, which has been approved by the Boards of Directors of General Mills and Blue Buffalo, is subject to regulatory approvals and other customary closing conditions, and is expected to close by the end of fiscal 2018 . Invus, LP and founding Bishop family shareholders, representing more than 50 percent of Blue Buffalo’s outstanding shares, have delivered written consents approving the transaction and no other approval of Blue Buffalo’s Board of Directors or shareho lders is requir ed to complete the transaction. We expect to report the consolidated results of Blue Buffalo as a segment in future periods. During the second quarter of fiscal 2017, we sold our Martel, Ohio manufacturing facility in our Convenience Stores & Foodservice segment and simultaneously entered into a co-packing arrangement with the purc haser. We received $17.5 million in cash, and recorded a pre-tax loss of $13.5 million.

RISK MANAGEMENT ACTIVITIES

RISK MANAGEMENT ACTIVITIES	9 Months Ended

Risk Management Activities [Abstract]
Risk Management Activities	( 6 ) Risk Management Activities 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 generall y 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 believe that these instruments are eff ective 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, certain gains and losses are reported in unallocated co rporate 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 the resulting mark-to-market volatility, which remains in unallocated corporate items. Unallocated corporate items for the quarters and nine -month periods ended February 25, 2018 and February 26, 2017 included: Quarter Ended Nine-Month Period Ended In Millions Feb. 25, 2018 Feb. 26, 2017 Feb. 25, 2018 Feb. 26, 2017 Net gain (loss) on mark-to-market valuation of certain commodity positions $ 0.3 $ - $ (8.1) $ (15.9) Net loss on commodity positions reclassified from unallocated corporate items to segment operating profit 4.6 4.0 10.7 27.7 Net mark-to-market revaluation of certain grain inventories (7.7) 4.2 0.9 8.9 Net mark-to-market valuation of certain commodity positions recognized in unallocated corporate items $ (2.8) $ 8.2 $ 3.5 $ 20.7 As of February 25, 2018 , the net notional value of commodity derivatives was $ 377.9 million, of which $ 106.1 million related to energy inputs and $ 271.8 million related to agricultural inputs. These contracts relate to inputs that generally will be utilized within the next 12 months. In advance of planned debt financing related to the planned acquisition of Blue Buffalo, in fiscal 2018, we entered into $3,500.0 million of treasury locks due April 19, 2018, with an average fixed rate of 2.9 percent, of which $2,300.0 million were entered into in the third quarter of fiscal 2018. As of February 25, 2018, the net fair value of the treasury locks was a liability of less than $1 million. In advance of planned d ebt financing, in fiscal 2018, we entered into $500 .0 million of treasury locks due October 15, 2017 with an average fixed rate of 1.8 percent. All of these treasury locks were cash settled for $3.7 million during the second quarter of fiscal 2018, concurr ent with the issuance of our $500.0 million 5-year fixed-rate notes. In advance of planned debt financing, during the third quarter of fiscal 2016 and the first quarter of fiscal 2017, we entered into $400 .0 million and $100 .0 million, respectively, of tr easury locks due February 15, 2017 with an average fixed rate of 2.0 percent. All of these treasury locks were cash settled for $17.2 million during the third quarter of fiscal 2017, concurrent with the issuance of our $750.0 million 10-year fixed-rate no tes. The fair values of the derivative positions used in our risk management activities and other assets recorded at fair value were not material as of February 25, 2018 , and were Level 1 or Level 2 assets and liabilities in the fair value hierarchy. We did not si gnificantly change our valuation techniques from prior periods. We off er certain suppliers access to third party service s that allow them to view our scheduled payments online. The third party service s also allow 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 wit h the suppliers, the third parties , or any financ ial institutions concerning these service s . All of our accounts payable remain as obligations to our su ppliers as stated in our supplier agreements. As of February 25, 2018 , $927 .0 million of ou r total accounts payabl e were payable to suppliers who utilize these third party services.

Debt	( 7 ) Debt The components of notes payable were as follows: In Millions Feb. 25, 2018 May 28, 2017 U.S. commercial paper $ 885.2 $ 954.7 Financial institutions 325.6 279.4 Total $ 1,210.8 $ 1,234.1 To ensure availability of funds, we maintain bank credit lines sufficient to cover our outstanding notes payable . Commercial paper is a continuing source of short-term financing. We have commercial paper programs available to us i n the United States and Europe. We also have committed, uncommitted, and asset-backed credit lines that support our foreign operations. In February 2018, we entered into a fee-paid commitment letter with certain lenders, pursuant to which such lenders have committed to provide a 364-day senior unsecured bridge term loan credit facility (the “Bridge Facility”) in an aggregate principal amount of up to $8.5 billion to provide the financing for the planned acquisition of Blue Buffalo. To the extent we obtain funding for the acquisition by issuing debt or equity securities, the availability of the Bridge Facility will be correspondingly reduced. The funding of the Bridge Facility is contingent on the satisfaction of certain customary conditions set forth in the commitment letter. The follow ing table details the fee-paid committed and uncommitted credit lines we had available as of February 25, 2018 : In Billions Facility Amount Borrowed Amount Credit facility expiring: February 2019 $ 8.5 $ - May 2022 2.7 - June 2019 0.2 0.2 Total committed credit facilities 11.4 0.2 Uncommitted credit facilities 0.5 0.2 Total committed and uncommitted credit facilities $ 11.9 $ 0.4 The credit facilities contain covenants, including a requirement to maintain a fixed charge coverage ratio of at least 2.5 times. We were in compliance with all credit facility covenants as of February 25, 2018 . Long-Term Debt The fair values and carrying amounts of long-term debt, including the current portion, were $ 8,512.6 million and $ 8,414.1 million, respectively , as of February 25, 2018 . 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. In February 2018, we paid $113.8 million to repurchase $100.0 million of our previously issue d 6.39% medium term notes due 2023. We recorded the $13.8 million premium paid in the repurchase as interest expense. In October 2017, we issued $500.0 million principal amount of 2.6 percent fixed-rate notes due October 12, 2022. Interest on the notes is payable semi-annually in arrears. We may redeem the notes in whole, or in part, at any time at the applicable redemption price. The notes are senior unsecured obligations that include a change of control repurchase provision. The net proceeds, together wi th cash on hand, were used to repay $500.0 million of 1.4 percent fixed-rate notes. In March 2017, we issued €300.0 million principal amount of floating-rate notes due March 20, 2019. Interest on the notes is payable quarterly in arrears. The notes are not generally redeemable prior to maturity. These notes are senior unsecured obligations that include a change of control repurchase provision. The net proceeds were used to repay a portion of our outstanding commercial paper. In February 2017, we repaid $1.0 billion of 5.7 percent fixed-rate notes. In January 2017, we issued $750.0 million principal amount of 3.2 percent fixed-rate notes due February 10, 2027. Interest on the notes is payable semi-annually in arrears. We may redeem the notes i n whole, or in part, at any time at the applicable redemption price. The notes are senior unsecured obligations that include a change of control repurchase provision. The net proceeds were used to repay a portion of our maturing long-term debt. Certain of our long-term debt agreements contain restrictive covenants. As of February 25, 2018 , we were in compliance with all of these covenants.

Redeemable and Noncontrolling Interests [Abstract]
Redeemable and Noncontrolling Interests	( 8 ) Redeemable and Noncontrolling Interests We have a 51 percent co ntrolling interest in Yoplait SAS and a 50 percent int erest in Yoplait Marques SNC and Liberté Marques Sàrl . Sodiaal International ( Sodiaal ) holds the remaining interests in each of the entities. On the acquisition date , we recorded the $904.4 million fair value of Sodiaal’s 49 percent euro-denomi nated interest in Yoplait SAS as a redeemable interest on our Consolidated Balance Sheets. Sodiaal has the ability to put all or a portion of its redeemable interest to us at fair value once per year, up to three times before December 2024. We adjust the value of the redeemable interest through additional paid-in capital on our Consolidated Balance She ets quarterly to the redeemable interest’s redemption value, which approximates its fair value. Yoplait SAS pays dividends annually if it meets certain financial metrics set forth in its shareholders’ agreement. As of February 25, 2018 , the redemption value of the euro-denominated redeemable i nterest was $817.5 million. A subsidiary of Yoplait SAS has an exclusive milk supply agreement for its European operations with Sodiaal through July 1, 202 1. Net purchases totaled $ 172.7 million for the nine -month period ended February 25, 2018 and $134.6 million for the nine -month period ended February 26, 2017 . On the acquisition dates, we recorded the $281.4 million fair value of Sodiaal’s 50 percent euro-denominated interest in Yoplait Marques SNC and 50 percent Canadian dollar-denominated interest in Liberté Marques Sàrl as noncontrolling interests on our Consolidated Balance Sheets. Yoplait Marques SNC earns a royalty stream through a licensing agreement with Yoplait SAS for the rights to Yoplait and related trademarks. Liberté Marques Sàrl earns a royalty stream through licensing agreements w ith certain Yoplait group companies for the rights to Libe rté and related trademarks. These entities pay dividends annually based on their availab le cash as of their fiscal year end. The third-party holder of the Class A Interests in our General Mills Cereals, LLC (GMC) consolidated subsidiary receives quarterly preferred distributions from available net income based on the application of a floati ng preferred return rate 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 Int erest holder or through a remarketing auction. On June 1, 2015, the floating preferred return rate on GMC’s Class A Interests was reset to the sum of three-month LIBOR plus 125 basis points. Our noncontrolling interests contain restrictive covenants. As o f February 25, 2018 , we were in compliance with all of these covenants.

Stock Plans	( 10 ) Stock Plans We have various stock-based compensation programs under which awards, including stock options, restricted stock, restricted stock units, and performance awards, may be granted to employees and non-employee directors. These programs and related accounting are described in Note 11 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended May 28, 2017 , and Note 17 to the Consolidated Financial Statements in Part I, Item 1 of this report .

As of February 25, 2018 , unrecognized compensation expense related to non-vested stock options, restricted stock units, and performance share units was $ 110.9 million. This expense will be recognized over 23 months, on average. Net cash pr oceeds from the exercise of stock options less shares used for withholding taxes and the intrinsic value of options exercised were as follows: Nine-Month Period Ended In Millions Feb. 25, 2018 Feb. 26, 2017 Net cash proceeds $ 91.4 $ 90.5 Intrinsic value of options exercised $ 79.9 $ 153.1 We estimate the fair value of each stock option on the grant date using a Black-Scholes option-pricing model. Black-Scholes option-pricing models require 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 stoc k 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 exp ected volatility. Our method of selecting the other valuation a ssumptions is explained in Note 11 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended May 28, 2017 .

Retirement and Postemployment Benefits [Abstract]
Retirement and Postemployment Benefits	( 14 ) Retirement and Postemployment Benefits In fiscal 2017, we changed the method used to estimate the service and interest cost components of the net periodic benefit expense for our United States and most of our international defined benefit pension, other postretirement benefit, and postemployment benefit plans. We adopted a full yield curve approach to estimate service cost and interest cost by applying the specific spot rates along the yield curve used to determine the benefit obligation to the relevant projected cash flows. This method provides a more precise measurement of service and interest costs by correlating the timing of the plans’ liability cash flows to the corresponding rate on the yield curve.

Income Taxes [Abstract]
Income Taxes	( 15 ) Income Taxes On December 22, 2017, the U.S. Tax Cuts and Jobs Act (TCJA) was signed into law. The TCJA results in significant revisions to the U.S. corporate income tax system, including a reduction in the U.S. corporate income tax rate, implementation of a territorial system and a one-time deemed repatriation tax on untaxed foreign earnings. The TCJA also results in a U.S. federal statutory blended rate of 29.4 percent for fiscal 2018. Generally, the impacts of the new legislation woul d be required to be recorded in the period of enactment which for us is the third quarter of fiscal 2018. However, Accounting Standards Update 2018-05: Income Taxes (Topic 740) (ASU 2018-05) was issued with guidance allowing for the recognition of provisi onal amounts in the event that the accounting is not complete and a reasonable estimate can be made. The guidance allows for a measurement period of up to one year from the enactment date to finalize the accounting related to the TCJA. As of February 25, 2018, we have not completed our accounting for the tax effects of the TCJA. During the third quarter of fiscal 2018, we recorded a provisional net benefit using reasonable estimates for those tax effects based on analysis and information available to dat e. The provisional net benefit is subject to revisions as we complete our analysis of the TCJA, collect and prepare necessary data, and interpret any additional guidance issued by the U.S. Treasury Department, Internal Revenue Service, Financial Accountin g Standards Board, and other standard setting and regulatory bodies. Adjustments may materially impact our provision for income taxes and effective tax rate in the period in which the adjustments are made. Our accounting for the tax effects of the TCJA w ill be completed during the measurement period of up to one year from the enactment date. During the third quarter of fiscal year 2018, we recorded an estimated net discrete benefit of $ 503.8 million. This net benefit consists primarily of a $ 617.8 milli on provisional deferred tax benefit from revaluing our net U.S. deferred tax liabilities to reflect the new U.S. corporate tax rate, partially offset by a n $83.9 million provisional charge for the estimated transition tax and an additional $30.1 million pr ovisional deferred tax liability related to changes in our assertion that we will reinvest unremitted foreign earnings indefinitely. Our estimate of the deferred tax benefit due to the revaluation of our net U.S. deferred tax liabilities is a provisional amount under the guidance in ASU 2018-05. Due to the newly enacted U.S. tax rate change, timing differences that are estimated balances as of the date of enactment will result in changes to our estimate of the deferred rate change when those estimates are finalized with the filing of our fiscal 2018 income tax return. This is a result of the different federal income tax rates of 29.4 percent and 21.0 percent for fiscal 2018 and fiscal 2019, respectively. Since many of the deferred tax balances in the period of enactment include estimates of events that have not yet occurred, we are unable to determine the final impact of the tax rate change at this time. As a result of the TCJA, we are re-evaluating our assertion regarding the indefinite reinvestment of for eign earnings for most legal entities owned directly by our U.S. subsidiaries, and as such, we may need to accrue additional deferred taxes related to any changes in our assertion. As of the end of the third quarter of fiscal 2018, we have recorded a provi sional estimate for local country withholding taxes related to certain entities from which we expect to repatriate undistributed earnings . However, we do not have the necessary information gathered, prepared and analyzed to make a reasonable estimate of th e deferred taxes related to the rest of our foreign subsidiaries where we may change our indefinite reinvestment assertion . We will gather the information necessary for those subsidiaries and record any new deferred taxes in future periods once the analysi s is complete . In general, the transition tax is a result of the deemed repatriation imposed by the new legislation that results in the taxation of our accumulated foreign earnings and profits (E&P) at a 15.5 percent rate on liquid assets (i.e. cash and o ther specified assets) and 8 percent on the remaining unremitted foreign E&P, both net of foreign tax credits. At this time, we have not yet gathered, prepared and analyzed the information necessary to complete the complex calculations required to finalize the amount of our transition tax. We believe that our provisional calculations result in a reasonable estimate of the transition tax and related foreign tax credit, and as such have included those amounts in our provisional estimate in the third quarter o f fiscal 2018. As we complete the analysis of accumulated foreign E&P and related foreign taxes paid on an entity by entity basis and finalize the amounts held in cash or other specified assets, we will update our provisional estimate of the transition tax and related foreign tax credit in a future period. The legislation also includes provisions that will affect our fiscal 2019 results, including but not limited to, a reduction in the U.S. corporate tax rate on domestic operations; the creation of a new m inimum tax called the base erosion anti-abuse tax; a new provision that taxes U.S. allocated expenses as well as currently taxes certain income from foreign operations (Global Intangible Low Tax Income or GILTI); a new limitation on deductible interest exp ense; the repeal of the domestic manufacturing deduction; and limitations on the deductibility of certain executive compensation. While the new legislation generally eliminates U.S. federal income tax on dividends from foreign subsidiaries going forward , certain income earned by certain subsidiaries must be included currently in our U.S. taxable income under the new GILTI inclusion rules. Because of the complexity of the new GILTI rules, we are evaluating this provision and the application of U.S. GAAP. Under U.S. GAAP, we are allowed to make an accounting policy election and record the taxes as a period cost as incurred or factor such amounts into the measurement of deferred taxes. We have not yet computed a reasonable estimate of the effect of this p rovision and therefore, have not made a policy decision regarding this item. In addition, in the third quarter of fiscal 2018, we adopted new accounting requirements that provide the option to reclassify stranded income tax effects resulting from TCJA fro m AOCI to retained earnings. We elected to reclassify the stranded income tax effects of the TCJA of $329.4 million from AOCI to retained earnings. This reclassification consists of deferred taxes originally recorded in AOCI that exceed the newly enacted federal corporate tax rate. The new accounting requirements allow for adjustments to reclassification amounts in subsequent periods as a result of changes to the provisional amounts recorded.

Business Segment Information [Abstract]
Business Segment Information	( 16 ) Business Segment Information We operate in the consumer foods industry. We have four operating segments by type of customer and geographic region as follows: North America Retail; Convenience Stores & Foodservice; Europe & Australia; and Asia & Latin America. Our North America Retail operating segment reflects business with a wide variety of grocery stores, mass merchandisers, membership stores, natural food chains, drug, dollar and discount chains, and e-commerce grocery providers. Our pr oduct categories in this business segment are ready-to-eat cereals, refrigerated yogurt, soup, meal kits, 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 refrigerated yogurt, nutrition bars, meal kits, salty snacks, ready-to-eat cereal, and grain snacks. Our major product categories in our Convenience Stores & Foodservice operating segment are ready-to-eat cereals, snacks, refrig erated yogurt, frozen meals, unbaked and fully baked frozen dough products, and baking mixes. 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 inc luding foodservice, convenience stores, vending, and supermarket bakeries in the United States. Our Europe & Australia operating segment reflects retail and foodservice businesses in the greater Europe and Australia regions. Our product categories include refrigerated yogurt, meal kits, super-premium ice cream, refrigerated and frozen dough products, shelf stable vegetables, grain snacks, and dessert and baking mixes. We also sell super-premium ice cream directly to consumers through owned retail shops. Rev enues from franchise fees are reported in the region or country where the end customer is located. Our Asia & Latin America operating segment consists of retail and foodservice businesses in the greater Asia and South America regions. Our product categorie s include super-premium ice cream and frozen desserts, refrigerated and frozen dough products, dessert and baking mixes, meal kits, salty and grain snacks, wellness beverages, and refrigerated yogurt. We also sell super-premium ice cream and frozen dessert s directly to consumers through owned retail shops. Our Asia & Latin America 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 int ernational joint ventures. Revenues from export activities are reported in the region or country where the end customer is located. Operating profit for these segments excludes unallocated corporate items, gain or loss on divestitures, and restructuring, i mpairment, and other exit costs. Unallocated corporate items include corporate overhead expenses, variances to planned domestic employee benefits and incentives, contributions t o the General Mills Foundation , restructuring initiative project-related costs, 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 positio ns 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 organiza tion, 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. Our operating segment results were as follows: Quarter Ended Nine-Month Period Ended In Millions Feb. 25, 2018 Feb. 26, 2017 Feb. 25, 2018 Feb. 26, 2017 Net sales: North America Retail $ 2,517.4 $ 2,499.0 $ 7,727.4 $ 7,804.8 Convenience Stores & Foodservice 460.3 448.5 1,419.6 1,382.3 Europe & Australia 469.8 424.5 1,428.4 1,338.0 Asia & Latin America 434.8 421.2 1,274.8 1,288.1 Total $ 3,882.3 $ 3,793.2 $ 11,850.2 $ 11,813.2 Operating profit: North America Retail $ 518.3 $ 516.7 $ 1,674.4 $ 1,795.9 Convenience Stores & Foodservice 84.3 93.6 275.6 295.4 Europe & Australia 27.3 42.0 84.8 127.2 Asia & Latin America (2.1) 10.0 30.1 61.3 Total segment operating profit 627.8 662.3 2,064.9 2,279.8 Unallocated corporate items 27.6 42.2 102.3 143.6 Divestiture loss - - - 13.5 Restructuring, impairment, and other exit costs 7.5 77.6 14.3 165.5 Operating profit $ 592.7 $ 542.5 $ 1,948.3 $ 1,957.2

New Accounting Pronouncements [Abstract]
New Accounting Pronouncements	( 17 ) New Accounting Pronouncements In the first quarter of fiscal 2018, we adopted new requirements for the accounting and presentation of stock-based payments. The adoption of this guidance resulted in the prospective recognition of realized windfall and shortfall tax benefits related to the exercise or vesting of stock-based awards in our Consolidated Statements of Earnings instead of additional paid-in capital within our Consolidated Balance Sheets. We recognized a windfall tax benefit in i ncome tax expense in our Consolidated Statements of Earnings of $ 6.6 million in the third quarter of fiscal 2018 and $ 26.8 million in the nine-month period ended February 25, 2018. We retrospectively adopted the guidance related to recla ssification of realized windfall tax benefits in our Consolidated Statements of Cash Flows. This resulted in reclassification s of $ 26.8 million and $65.1 million of cash provided by financing activities to operating activities for the nin e-month periods ended February 25, 2018 and February 26, 2017 , respectively. Additionally, we retrospectively adopted the guidance related to reclassification of employee tax withholdings in our Consolidated Statements of Cash Flows. This resulted in reclass ifications of $ 21.4 million and $35.2 million of cash used by operating activities to financing activities for the nine-month periods ended February 25, 2018 and February 26, 2017 , r espectively. Stock-based compensation expense continues to reflect estimated forfeitures. In the first q uarter of fiscal 2018, we adopted new accounting requirements which permit reporting entities to measure a goodwill impairment loss by the amount by which a reporting unit’s carrying value exceeds the reporting unit’s fair value. Previously, goodwill impai rment losses were required to be measured by determining the implied fair value of goodwill. Our annual goodwill impairment test was performed as of the first day of the second quarter of fiscal 2018, and the adoption of this guidance did not impact our res ults of operations or financial position.

Share-based Compensation Arrangement by Share-based Payment Award, Options, Additional Disclosures [Abstract]
Share-based Compensation Arrangement by Share-based Payment Award, Fair Value Assumptions, Method Used	We estimate the fair value of each stock option on the grant date using a Black-Scholes option-pricing model. Black-Scholes option-pricing models require 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 method of selecting the other valuation assumptions is explained in Note 11 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended May 28, 2017.
