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 o f those transactions, are eliminated in consolidation. Our fiscal year ends on the last Sunday in May. Certain reclassifications to our previously reported financial information have been made to conform to the current period presentation. See Note 2 for additional information. Change in Rep orting Period As part of a long-term plan to conform the fiscal year ends of al l our operations, in fiscal 2017 we changed the reporting period of General Mills Brasil Alimentos Ltda (Yoki) within our Asia & Latin America segment from an April fiscal year -end to a May fiscal year-end to match our fiscal calendar. Accordingly, in fiscal 2017 , our results included 13 months of results from the affected operations. The impact of these changes was not material to our consolidated results of operations. Our Gen eral Mills India business and Pet operating segment are on an April fiscal year end.

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 are valued at net realizable value, and all related cash contracts and derivatives are valued at fair value, 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 net realizable value. 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 ac cepted 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 u sually depreciated over 40 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 26, 2019 , assets h eld 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 e stimated 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. We perform our annual goodwill and indefinite-lived intangible assets impairment test as of the first day of the second quarter of the fiscal year. 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, impairment has occurred . We recognize an impairment charge for the amount by which the carrying amount o f the reporting unit exceeds it s fair value up to the total amount of goodwill allocated to the reporting unit. Our estimates of fair value are determined based on a discounte d 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, competit ion, 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 main tenance 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 Blue Buffalo , Pillsbury , Totino’s , Yoplait , Old El Paso , Progresso , Annie’s , Hä agen-Dazs , and Yoki brands, are also tested for impairment annually and whenever events or change s in circumstances indicate that their carrying value may not be recoverable. Our estimate of the fair value of the brands is 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 whene ver 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 Unconsolidated 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, as a result of ongoing operating losses, projected decreases in earnings, increases in the weighted - average cost of capital, or significant business disruptions. The significant assumptions used to estimat e 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 conclude d the impairment is othe r than temporary. Redeemable Interest We have a 51 percent control ling interest in Yoplait SAS , a consolidated entity. Sodiaal International (Sodiaal) holds the remaining 49 pe rcent interest in Yoplait SAS. 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 . 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 th e 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 c apital on our Consolidated Balance Sheets quarterly to the redeemable interest’s redemption value, which approximates its fair value. During the second and fourth quarters of fiscal 2019 , we adjusted the redeemable interest’s redemption value based on a disco unted 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 exchange rates, and a discount rat e. Revenue Recognition Our revenues primarily result from contracts with customers, which are generally short-term and have a single performance obligation – the delivery of product. We recognize revenue for the sale of packaged foods at the point in time when our performance ob ligation has been satisfied and control of the product has transferred to our customer, which generally occurs when the shipment is accepted by our customer. Sales include shipping and handling charges billed to the customer and are reported net of variabl e consideration and consideration payable to our customers, including trade promotion, consumer coupon redemption and other costs, including estimated allowances for returns, unsalable product, and prompt pay discounts. Sales, use, value-added, and other e xcise taxes are not included in revenue. Trade promotions are recorded using significant judgment of estimated participation and performance levels for offered programs at the time of sale. Differences between estimated expenses and actual costs are recogn ized as a change in management estimate in a subsequent period. 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. Payment terms and collection patterns are short-term, and vary around the world and by channel, and as such, we do not have any signif icant financing components. Our 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 ba lances are written off against the allowance when we deem the amount is uncollectible. Please see Note 16 for a disaggregation of our revenue into categories that depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. We do not have material contract assets or liabilities arising from our contracts with customers. Environmenta l Costs Environmental costs relating to existing conditions caused by past operations that do not contribute to current or futur e 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 actio n. 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 period incu rred. R&D includes expenditures for new product and manufacturing process innovation, and the annual expenditures are comprised primarily of internal salari es, wages, consulting, and supplies attributable to 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 exchan ge rates prevailing during the period . Translation adjustments are reflected within accumula ted 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 f oreign exchange gains and losses on instruments designated as net investment hedges. These gains and losses are recorded in AOCI . Derivative Instruments All d erivatives are recognized on our Consolidated Balance Sheets at fair value based on quoted marke t 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 whe ther 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 compensa tion expense for grants of restricted stock units and performance share units using the value of a share of our stock on the date of grant. We estimate the value of stoc k option grants using a Black- Scholes valuation model. Generally, s tock -based compensat ion is recognized straight line over the vesting period. Our stock -based compensation expense is recorded in selling, general and administrative ( SG&A ) expenses and cost of sales in our Consolidated Statements of Earnings and allocated to each reportable s egment 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 generally recogniz ed 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 recog nized compensation cost as an operating cash flow . 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 be nefits to retired employees. Under certain circumstances, we also provide accruable benefits , primarily severance, to former or inactive employees in the United States , Canada , and Mexico. 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 . In fiscal 2018, we approved an amendment to reorga nize the U.S. qualified defined benefit pension plans and the supplemental pension plans that resulted in the spinoff of a portion of the General Mills Pension Plan (the Plan) and the 2005 Supplemental Retirement Plan and the Supplemental Retirement Plan ( Grandfathered) (together, the Supplemental Plans) into new plans effective May 31, 2018. The benefits offered to the plans’ participants were unchanged. The result of the reorganization was the creation of the General Mills Pension Plan I (Plan I) and th e 2005 Supplemental Retirement Plan I and the Supplemental Retirement Plan I (Grandfathered) (together, the Supplemental Plans I). The reorganization was made to facilitate a targeted investment strategy over time and to provide additional flexibility in evaluating opportunities to reduce risk and volatility. Actuarial gains and losses associated with the Plan and the Supplemental Plans are amortized over the average remaining service period of the active participants. Actuarial gains and losses associat ed with the Plan I and the Supplemental Plans I are amortized over the average remaining life of the participants. Please refer to Note 13 for a description of our defined benefit pension, other postretirement benefit, and postemployment benefit plans. U se 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, disclosu res 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 as sets, intangible assets, redeemable interest, stock-based compensation, income taxes, and defined benefit pension, other p ostretirement benefit and postemployment benefit plans . Actual results could differ from our estimates. New Accounting Standards In the first quarter of fiscal 2019, we adopted new accounting requirements related to the presentation of net periodic defined benefit pension expense, net periodic postretirement benefit expense, and net periodic postemployment benefit expense (collectively “net periodic benefit expense”). The new standard requires the service cost component of net periodic benefit expense to be recorded in the same line items as other employee compensation costs within our Consoli dated Statements of Earnings. Other components of net periodic benefit expense must be presented separately outside of operating profit in our Consolidated Statements of Earnings. In addition, the new standard requires that only the service cost component of net periodic benefit expense is eligible for capitalization. The new standard requires retrospective adoption of the presentation of net periodic benefit expense and prospective application of the capitalization of the service cost component. The impact of the adoption of this standard on our results of operations was a decrease to our operating profit of $87.9 million, $89.4 million and $74.3 million and a corresponding increase to benefit plan non-service income of $87.9 million, $89.4 million and $74. 3 million for fiscal 2019, fiscal 2018 and fiscal 2017, respectively. There were no changes to our reported segment operating profit. In the first quarter of fiscal 2019, we adopted new accounting requirements for the recognition of revenue from contracts with customers. Under the new standard, we apply a principles-based five step model to recognize revenue upon the transfer of control of promised goods to customers and in an amount that reflects the consideration for which we expect to be entitled to in exchange for those goods. The principles-based five step model includes: 1) identifying the contract(s) with a customer; 2) identifying the performance obligations in the contract; 3) determining the transaction price; 4) allocating the transaction price t o the performance obligations in the contract; and 5) recognizing revenue when (or as) we satisfy a performance obligation. We utilized a comprehensive approach to evaluate and document the impact of the guidance on our current accounting policies and prac tices. We did not identify any material differences resulting from applying the new requirements to our revenue contracts. Additionally, we did not identify any significant changes to our business processes, systems, and controls to support recognition and disclosure requirements under the new guidance. We adopted the requirements of the new standard and subsequent amendments to all contracts in the first quarter of fiscal 2019 using the cumulative effect approach. We recorded a $33.9 million cumulative eff ect adjustment net of income tax effects to the opening balance of fiscal 2019 retained earnings, a decrease to deferred income taxes of $11.4 million, and an increase to other current liabilities of $45.3 million related to the timing of recognition of ce rtain promotional expenditures. In the third quarter of fiscal 2018, we adopted new accounting requirements that codify Securities and Exchange Commission (SEC) Staff Accounting Bulletin No. 118, as it relates to allowing for recognition of provisional am ounts related to the U.S. Tax Cuts and Jobs Act (TCJA) in the event that the accounting is not complete and a reasonable estimate can be made. Where necessary information is not available, prepared, or analyzed to determine a reasonable estimate, no provis ional amount should be recorded. The guidance allows for a measurement period of up to one year from the enactment date to finalize the accounting related to the TCJA. In fiscal 2019, we completed our accounting for the tax effects of the TCJA. In the thi rd quarter of fiscal 2018, we adopted new accounting requirements that provide the option to reclassify stranded income tax effects resulting from the TCJA from 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 consisted of deferred taxes originally recorded in AOCI that exceeded the newly enacted federal corporate tax rate. The new accounting requirements allowed for adjustments to reclassi fication amounts in subsequent periods as a result of changes to the provisional amounts recorded. 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 r esulted 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 retrospectively adopted the guidance related to reclassification of realized windfall tax benefits , which resulted in reclassifications of cash provided by financing activities to operating activities in our Consolidated Statements of Cash Flow s. Additionally, we retrospectively adopted the guidance related to reclassification of employee tax withholdings , which resulted in reclassifications of cash used by operating activities to financing activities in our Consolidated Statements of Cash Flows . Stock-based compensation expense continues to reflect estimated forfeitures. In the first quarter of fiscal 2018, we adopted new accounting requirements which permit reporting entities to measure a goodwill impairment loss by the amount by which a report ing unit’s carrying value exceeds the reporting unit’s fair value. Previously, goodwill impairment 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 results of operations or financial position. In the first quarter of fiscal 2017, we adopted new accounting requirements for the presentation of certain investments using the net asset value, providing a practical expedient to exclude such investments from categorization within the fair value hierarchy and separate disclosure. We adopted the guidance retrospectively and restated the fiscal 2016 fair value of plan asset tables in Note 13. The adoption of this guidance did not impact our results of operations or financial position. In the first quarter of fiscal 2017, we adopted new accounting requirements which permit reporting entities with a fiscal year -end that does not coincide with a month-end to apply a practical expedient that permits the entity to measure defined benefit plan assets and obligations using the month-end that is closest to the entity’s fiscal year-end and apply such practical expedien t consistently to all plans. The adoption of this guidance did not have a material impact on our results of operations or financial position.

ACQUISTION AND DIVESTITURES [Abstract]
ACQUISITION AND DIVESTITURES	NOTE 3 . ACQUISITION AND DIVESTITURES During the third quarter of fiscal 2019, we sold our La Salteña fresh pasta and refrigerated dough business in Argentina, and recorded a pre-tax loss of $35.4 million. During the fourth quarter of fiscal 2019, we sold our yogurt business in China and simultaneously entered into a new Yoplait license agreement with the purchaser for their use of the Yoplait brand. We recorded a pre-tax gain of $5. 4 million During the fourth quarter of fiscal 2018, we acquired Blue Buffalo Pet Products, Inc. (“Blue Buffalo”) for an aggregate purchase price of $8.0 billion, including $103.0 million of consideration for net debt repaid at the time of the acquisition. In accordance with the definitive agreement and plan of merger, a subsidiary of General Mills merged into Blue Buffalo, with Blue Buffalo surviving the merger as a wholly owned subsidiary of General Mills. In accordance with the merger agreeme nt, equity holders of Blue Buffalo received $40.00 per share in cash. We financed the transaction with a combination of $6.0 billion in debt, $1.0 billion in equity, and cash on hand. In fiscal 2019, we recorded acquisition integration costs of $25.6 milli on in SG&A expenses. In fiscal 2018, we recorded acquisition transaction and integration costs of $34.0 million in SG&A expenses and $49.9 million in interest, net related to the debt issued to finance the acquisition. We consolidated Blue Buffa lo into our Consolidated Balance Sheets and recorded goodwill of $5.3 billion, an indefinite-lived intangible asset for the Blue Buffalo brand of $2.7 billion, and a finite-lived customer relationship asset of $269.0 million. The goodwill was primarily att ributable to future growth opportunities and any intangible assets that did not qualify for separate recognition. The goodwill is included in the Pet reporting unit and is not deductible for tax purposes. In the fourth quarter of fiscal 2019, we recorded a djustments to certain purchase accounting liabilities that resulted in a $5.6 million increase to goodwill. The consolidated results of Blue Buffalo are reported as our Pet operating segment on a one-month lag. The following unaudited supplemental pro forma information is presented as if we had acquired Blue Buffalo at the beginning of fiscal 2017: Unaudited Fiscal Year In Millions 2018 2017 Net sales $ 17,057.4 $ 16,772.9 Net earnings attributable to General Mills 2,252.4 1,540.2 The fiscal 2017 pro forma amounts include transaction and integration costs of $83.9 million and the purchase accounting adjustment to record inventory at fair value of $52.7 million. The fiscal 2017 and fiscal 2018 pro forma amounts include interest expen se of $238.7 million on the debt issued to finance the transaction and amortization expense of $13.5 million based on the estimated fair value and useful life of the customer relationships intangible asset. Additionally, the pro forma amounts include an in crease to cost of sales by $1.6 million in fiscal 2017 and $5.1 million in fiscal 2018 to reflect the impact of using the LIFO method of inventory valuation on Blue Buffalo’s historical operating results. Pro forma amounts include related tax effects of $ 125.1 million in fiscal 2017 and $14.5 million in fiscal 2018. Unaudited pro forma amounts are not necessarily indicative of results had the acquisition occurred at the beginning of fiscal 2017 or of future results.

RESTRUCTURING, IMPAIRMENT, AND OTHER EXIT COSTS [Abstract]
RESTRUCTURING, IMPAIRMENT, AND OTHER EXIT COSTS	NOTE 4 . RESTRUCTURING , IMPAIRMENT, AND OTHER EXIT COSTS ASSET IMPAIRMENTS In fiscal 2019, we recorded a $ 192.6 million charge related to the impairment of our Progresso , Food Should Taste Good , and Mountain High brand intangible assets in restructuring, impairment, and other exit costs. Please see Note 6 for additional information . In fiscal 2019, we recorded a $ 14.8 million charge in restructuring, impairment, and other exit costs related to the impairment of certain manufacturing assets in our North America Retail and Asia & Latin America segments. In fiscal 2018, we recorded a $ 96.9 million charge related to the impairment of our Yoki , Mountain High , and Immaculate Baking brand intangible assets in restructuring, impairment, and other exit costs. RESTRUCTURING INITIATIVES 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. Accelerated depreciation associated with restructured assets, as used in the context of our disclosures regarding restructuring activity, refers to the increase in deprec iation 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 t he plan is approved . Charges recorded in fiscal 2019 were as follows: Expense, in Millions Targeted actions in global supply chain $ 80.2 Charges associated with restructuring actions previously announced (2.6) Total $ 77.6 In fiscal 2019, we approved restructuring actions to drive efficiencies in targeted areas of our global supply chain. In our North America Retail segment, we approved actions at certain facilities to consolidate production and optimize our labor and manufacturing platforms. In connection with these actions we will exit our Carson, California yogurt manufacturing facility. We expect to incur approximately $ 101 million of restructuring charges related to these actions, including $ 10 million of severance expense and $ 91 million of other costs, primarily asset write-offs. We also expect to incur approximately $ 2 million of project-related costs. We recorded $ 9.9 million of severance and $ 44. 5 million of other costs in fiscal 2019. In fiscal 2019, we approved targeted systems and process optimization actions in our Europe & Australia segment and expect to incur approximately $ 15 million of restruc turing charges, including $ 11 million of severance expense and $ 4 million of other costs. We recorded $ 11.3 million of severance and $ 0. 7 million of other costs in fiscal 2019. In fiscal 2019, w e decided to exit underperforming product lines in our Asia & Latin America segment and expect to incur approximately $ 14 million of restructuring charges, including $ 1 million of severance expense and $ 1 3 million of other costs, primarily asset write-offs. We recorded $ 1.0 million of severance and $ 11.5 million of o ther costs in fiscal 2019. In fiscal 2019, w e decided to exit underperforming markets in our Pet segment and expect to incur approximately $ 8 million of restructuring charges, including $ 2 million of severance expense and $ 6 million of other costs, primari ly asset write-offs. We recorded $ 0.8 million of severance and $ 0.5 million of other costs in fiscal 2019. Certain of these global supply chain actions are subject to union negotiations and works counsel consultations, where required. We expect to spend approximately $ 3 5 million of cash related to these actions and spent $ 1.7 million in fiscal 2019. We expect these actions to be completed by the end of fiscal 2022. In fiscal 2019, we paid $ 49.3 million in cash related to restructuring initiatives in fis cal 2019.

In fiscal 2018, we acquired Blue Buffalo , which became our Pet operating segment and we recorded $5.3 billion of goodwill, $2.7 billion related to an indefinite-lived brand intangible asset, and $269.0 million related to a customer relationships intangible asset. In the fourth quarter of fiscal 2019, we recorded adjustments to certain purchase accounting liabilities that resulted in a $ 5.6 million increase to goodwill.

In fiscal 2018, we recorded a $ 96.9 million charge related to the impairment of our Yoki , Mountain High , and Immaculate Baking brand intangible assets in restructuring, impairment, and other exit costs. Significant assumptions used in that assessment included our long-range cash flow projections for the businesses, royalty rates, weighted- average cost of capital rates, and tax r ates.

FINANCIAL INSTRUMENTS, RISK MAN A GEMENT ACTIVITIES, AND FAIR VALUES 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 26, 2019 and May 27, 2018 , a comparison of cost and market values of our marketable debt and equity securities is as follows: Cost Fair Value Gross Gains Gross Losses Fiscal Year Fiscal Year Fiscal Year Fiscal Year In Millions 2019 2018 2019 2018 2019 2018 2019 2018 Available for sale debt securities $ 34.3 $ 25.4 $ 34.3 $ 25.4 $ - $ - $ - $ - Equity securities 0.6 0.3 18.5 3.5 17.9 3.2 - - Total $ 34.9 $ 25.7 $ 52.8 $ 28.9 $ 17.9 $ 3.2 $ - $ - There were no realized gains or losses from sales of marketable securities in fiscal 2019. In fiscal 2018, we realized $6.8 million of gains from the sale 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 peri od and the security’s maturity date. The aggregate unrealized gains and losses on avail able-for-sale debt securities, net of tax effects, are classified in AOCI within stockholders’ equity. Scheduled maturities of our marketable securities are as follows: Marketable Securities In Millions Cost Fair Value Under 1 year (current) $ 34.3 $ 34.3 Equity securities 0.6 18.5 Total $ 34.9 $ 52.8 As of May 26, 2019 , we had $2.3 million of certain marketable debt securities pledged as collateral for derivative contracts. As of May 26, 2019 , $ 34.8 million of certain accounts receivable wer e 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 $13,272.8 million and $ 13,021.3 million, respectively, as of May 26, 2019 . The fair value of long-term debt was estimated using market quotations and disco unted 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 su ch as changes in interest and foreign cu rrency 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 conditio ns 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 believe that these instruments are effective in achieving our objective of providing certainty in the future pri ce 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 e xposure 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 r esulting mark-to-market volatility, which remains in unallocated corporate items. Unallocated corporate items for fiscal 2019 , 2018 and 2017 included: Fiscal Year In Millions 2019 2018 2017 Net gain (loss) on mark-to-market valuation of commodity positions $ (39.0) $ 14.3 $ (22.0) Net loss on commodity positions reclassified from unallocated corporate items to segment operating profit 10.0 11.3 32.0 Net mark-to-market revaluation of certain grain inventories (7.0) 6.5 3.9 Net mark-to-market valuation of certain commodity positions recognized in unallocated corporate items $ (36.0) $ 32.1 $ 13.9 As of May 26, 2019 , the net notional value of c ommodity derivatives was $ 312.5 million , of which $ 242.9 million related to agricultural inputs and $ 69.6 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 proportio n of fixed rate 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 met hod 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 fiscal 2019 , a $2.6 million loss in fiscal 2018 , and less than $1 million in fiscal 2017 . Fixed Interest Rate Exposures — Fixed-to-floating interest rate swaps are accounted for as fair valu e 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 derivati ves and the underlying hedged items are recorded as net interest. The amount of hedge ineffectiveness was a $ 2.4 million gain in fiscal 2019 , a $3.4 million loss in fiscal 2018, and a $ 4.3 million gain in fiscal 201 7. In advance of planned debt financing rela ted to the acquisition of Blue Buffalo, we entered into $3,800.0 million of treasury locks due April 19, 2018, with an average fixed rate of 2.9 percent . All of these treasury locks were cash settled for $43.9 million during the fourth quarter of fiscal 2018, concurrent with the issuance of our $850.0 million 5.5-year fixed-rate notes, $800.0 million 7- year fixed-rate notes, $1,400.0 million 10-year fixed-rate notes, $500.0 million 20-year fixed-rate notes, and $650.0 million 30-year fixed-rate notes. In advance of planned debt financing, in fiscal 2018, we entered into $500.0 million of treasury locks d ue 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, concurrent with the issuance of our $500.0 million 5-year fixed-rate notes. As of May 26, 2019 , 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) 3.15% notes due December 15, 2021 $ (25.3) 2.6% notes due October 12, 2022 2.5 1.0% notes due April 27, 2023 (0.9) 3.7% notes due October 17, 2023 (1.5) 3.65% notes due February 15, 2024 8.4 4.0% notes due April 17, 2025 (3.4) 3.2% notes due February 10, 2027 13.2 1.5% notes due April 27, 2027 (2.6) 4.2% notes due April 17, 2028 (9.1) 4.55% notes due April 17, 2038 (10.3) 5.4% notes due June 15, 2040 (11.8) 4.15% notes due February 15, 2043 9.3 4.7% notes due April 17, 2048 (13.7) Net pre-tax hedge loss in AOCI $ (45.2) The following table summarizes the notional amounts and weighted-average interest rates of our interest rate derivatives. Average floating rates are based on rates as of the end of the reporting period. In Millions May 26, 2019 May 27, 2018 Pay-floating swaps - notional amount $ 500.0 $ 500.0 Average receive rate 2.2 % 2.2 % Average pay rate 3.1 % 2.9 % The swap contracts outstanding as of May 26 , 2019 mature in fiscal 2020. 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 debt. 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, Mexican peso, and Swiss franc. We primarily 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 tha n 18 months in advance. As of May 26, 2019 , the net notional value of foreign exchange derivatives was $ 1,008.5 million. The amount of hedge ineffectiveness was less than $1 million in fiscal 2019 , 2018 , and 2017 . We also have 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. As of May 26, 2019 , we hedged a port ion of these net investments with €2,200.0 million of euro de nominated bonds. As of May 26, 2019 , we had deferred net foreign currency transaction losses of $51.5 million in AOCI associated with net investment hedging activity. EQUITY INSTRUMENTS Equity price movements affect our compensation expense as certain inves tments made by our employees in our deferred compensation plan are revalued . We use equity swaps to manage this risk . As of May 26, 2019 , the net notional amount of our equity swaps was $169.1 million . These swap contracts mature in fiscal 2020 . FAIR VALUE MEASUREMENTS AND FINANCIAL STATEMENT PRESENTATION The fair values of our assets, liabilities, and derivative positions recorded at fair value and their respective levels in the fair value hierarchy as of May 26, 2019 and May 27, 2018 , were as follows: May 26, 2019 May 26, 2019 Fair Values of Assets Fair Values of Liabilities In Millions Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Derivatives designated as hedging instruments: Interest rate contracts (a) (b) $ - $ - $ - $ - $ - $ (1.9) $ - $ (1.9) Foreign exchange contracts (c) (d) - 12.9 - 12.9 - (3.3) - (3.3) Total - 12.9 - 12.9 - (5.2) - (5.2) Derivatives not designated as hedging instruments: Foreign exchange contracts (c) (d) - 2.4 - 2.4 - (1.9) - (1.9) Commodity contracts (c) (e) 1.4 5.2 - 6.6 (4.4) (3.5) - (7.9) Grain contracts (c) (e) - 6.7 - 6.7 - (2.3) - (2.3) Total 1.4 14.3 - 15.7 (4.4) (7.7) - (12.1) Other assets and liabilities reported at fair value: Marketable investments (a) (f) 18.5 34.3 - 52.8 - - - - Long-lived assets (g) - 19.0 - 19.0 - - - - Indefinite-lived intangible assets (h) - - 330.0 330.0 - - - - Total 18.5 53.3 330.0 401.8 - - - - Total assets, liabilities, and derivative positions recorded at fair value $ 19.9 $ 80.5 $ 330.0 $ 430.4 $ (4.4) $ (12.9) $ - $ (17.3) (a) These contracts and investments are recorded as prepaid expenses and other current assets, other assets, other current liabilities or other liabilities, as appropriate, based on whether in a gain or loss position.

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 feature s that were in a liability position on May 26, 2019 , was $ 7.4 million . We have posted no collateral under these contracts. If the credit- risk-related contingent features underlying these agreements had been triggered on May 26, 2019 , we would have been required to post $ 7.4 million of collateral to counterparties. CONCENTRATIONS OF CREDIT AND COUNTERPARTY CREDIT RISK During fiscal 2019 , customer concentration was as follows: Percent of total Consolidated North America Retail Convenience Stores & Foodservice Europe & Australia Asia & Latin America Pet Walmart (a): Net sales 20% 31% 7% 1% 4% 3% Accounts receivable 22% 3% 1% 6% 9% Five largest customers: Net sales 55% 45% 24% 12% 69% (a) Includes Walmart Inc. and its affiliates. No customer other than Walmart accounted for 10 percent or more of our consolidated 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 fut ures 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 $ 2.4 million against which we do not hold collat eral. 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. Tre asury instruments and are held in a trust account that we may access if the counterparty defaults . We offer certain suppliers access to third party services that allow them to view our scheduled payments online. The third party services also allow supplie rs 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 parties, or any financial ins titutions concerning this service. All of our accounts payable rem ain as obligations to our suppliers as stated in our supplier agreements. As of May 26, 2019 , $ 1,049.8 million of our accounts payable is payable to suppliers who utilize these third party service s.

REDEEMABLE AND NONCONTROLLING INTERESTS Our principal redeemable and noncontrolling interests relate to our Yoplait SAS, Yoplait Marques SNC, Liberté Marques Sàrl, and General Mills Cereals, LLC (GMC) subsidiaries. In addition, we have 4 foreign subsidiaries that have noncontrolling interests totaling $4.9 million as of May 26, 2019 . We have a 51 percent controlling interest in Yoplait SAS and a 50 percent interest in Yoplait Marques SNC and Liberté Marques S àrl . 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 redee mable interest on our Consolidated Balance S heets. Sodiaal has the ability to p ut 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 add itional paid-in capital on our Consolidated Balance S heets quarterly to the redeemable interest’s redemption value, which approximate s its fair value . Yoplait SAS pays dividends annually if it meets certain financial metrics set forth in its shareholders ’ agreement. As of May 26, 2019 , the redemption value of the euro-denominated rede emable interest was $ 551.7 million. 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 S àrl as noncontrolling interests on our Consolidated Balance Sheets. Yoplait Marques SNC earns a royalty stream through a licensing agr eement with Yoplait SAS for the rights to Yoplait and related trademarks. Liberté Marques S àrl earns a royalty stream through licensing agreements with certain Yoplait group companies for the rights to Liberté and related trademarks. These enti ties pay div idends annually based on their available cash as of their fiscal year end. We paid dividends of $22.0 million in fiscal 2019 and $ 37.7 million in fiscal 2018 to Sodiaal under the terms of the Yoplait SAS, Yoplait Marques SNC, and Liberté Marques Sàrl shareho lder agreements. A subsidiary of Yoplait SAS 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 $210.8 million for fiscal 2019 and $230.8 million for fiscal 2018 . During the second quarter of fiscal 2019, Sodiaal invested $ 55.7 million in Yoplait SAS. The holder of the GMC Class A Interests receives quarterly preferred distributions from available net income based on the application of a flo ating preferred return rate to the holder’s capital account balance established in the most recent mark-to-market valuation ( currently $ 251.5 million ). On June 1, 201 8 , the floating preferred return rate on GMC’s Class A interests was reset to the su m of t hree-month LIBOR plus 1 42.5 basis points. 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 consolidated 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 attribut able to redeemable and noncontrolling interests in our Consolidated Statements of Earnings. Our noncontrolling interests contain restrictive covenants. As of May 26, 2019 , we were in compliance with all of these covenants.

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 s hareholders . As of May 26, 2019 , a total of 30.3 million shares were available for grant in the form of stock options, restricted stock, restricted stock units, and shares of unrestricted stock under the 2017 Stock Compensation Plan (2017 Plan). The 2017 Plan also provides for the issuance of cash-settled share-based units, stock appreciation rights, and performance-based stock awards. Stock-based awards now outstanding include some granted under the 2007, 2009 , and 2011 stock plans and the 2006 and 2011 compensation plan s for non-employee directors, under which no fur ther awards may be granted. The stock plans provide for potential 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 2019 2018 2017 Estimated fair values of stock options granted $5.35 $6.18 $8.80 Assumptions: Risk-free interest rate 2.9 % 2.2 % 1.7 % Expected term 8.5 years 8.2 years 8.5 years Expected volatility 16.3 % 15.8 % 17.8 % Dividend yield 4.3 % 3.6 % 2.9 % 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, dividend yield, and the forfeiture rate. 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 volat ility. 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 volatili ty. 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 exp ected 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 our Consolidated Statements of Cash Flows as an operating cash flow. Realized windfall tax benefits and shortfall tax deficiencies related to the exercise or vesting of stock-based awards are recognized in the Co nsolidated Statement of Earnings. We recognized windfall tax benefits from stock-based payments in income tax expense in our Consolidated Statements of Earnings of $ 24.5 million in fiscal 2019 and $ 25.5 million in fiscal 2018. Options may be priced at 1 00 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. Information on stock option activity follows: Options Outstanding (Thousands) Weighted-Average Exercise Price Per Share Weighted-Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (Millions) Balance as of May 27, 2018 28,963.8 $ 42.90 Granted 3,149.8 46.09 Exercised (7,968.1) 30.96 Forfeited or expired (492.5) 53.73 Outstanding as of May 26, 2019 23,653.0 $ 47.12 4.82 $ 180.0 Exercisable as of May 26, 2019 14,219.0 41.80 2.79 $ 159.8 Stock-based compensation expense related to stock option awards was $ 14.7 million in fiscal 2019 , $ 15.5 million in fiscal 2018 , and $ 18.0 million in fiscal 2017 . Compensation expense related to stock-based payments recognized in our Consolidated Statements of Earnings includes amounts recognized in restructuring, impairment, and other exit costs for fiscal 2018 and 2017 . Net cash proceeds from the exercise of stock options less shares used for minimum withholding taxes and the intrinsic value of options exercised were as follows: Fiscal Year In Millions 2019 2018 2017 Net cash proceeds $ 241.4 $ 99.3 $ 112.6 Intrinsic value of options exercised $ 126.7 $ 83.6 $ 176.5 Restricted Stock, Restricted Stock Units, and Performance Share 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 2017 Plan. Restricted stock and restricted stock units generally vest and become unrestricted four years after the date of grant. Performance share units are earned primarily based on our future achievement of three-year goals for a verage organic net sales growth and cumulative free cash flow. Performance share units are settled in common stock and are generally subject to a three year performance and vesting period. The sale or transfer of these awards is restricted during the vesti ng period. Participants holding restricted stock, but not restricted stock units or performance share units, are entitled to vote on matters submitted to holders of common stock for a vote. These awards accumulate dividends from the date of grant, but part icipants only receive payment if the awards vest.

As of May 26, 2019 , unrecognized compensation expense related to non-vested stock options, restricted stock units, and performance share units was $ 98.4 million. This expense will be recognized over 21 mon ths, on average. Stock-based compensation expense related to restricted stock units and performance share units was $ 70.2 million for fiscal 2019 , $62.4 million for fiscal 2018 , and $77.9 million for fiscal 2017 . Compensation expense rela ted to stock-based payments recognized in our Consolidated Statements of Earnings includes amounts recognized in restructuring, impairment, and other exit costs for fiscal 2019, 2018 , and 2 017.

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 many employees in the United States, Canada, Switzerland, 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 appl icable laws. We made no voluntary contributions to our principal U.S. plans in fiscal 2019 or 2018 . We do not expect to be required to make any contributions in fiscal 2020 . Our principal domestic retirement plan covering salaried emp loyees 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. All salaried employees hired on or after June 1, 2013, are eligible for a retirement program that does not include a defined benefit pension plan. In fiscal 2018, we approved an amendment to reorganize the U.S. qualified defined benefit pension plans and the supplemental pension plans that resulted in the spinoff of a portion of the General Mil ls Pension Plan (the Plan) and the 2005 Supplemental Retirement Plan and the Supplemental Retirement Plan (Grandfathered) (together, the Supplemental Plans) into new plans effective May 31, 2018. The benefits offered to the plans’ participants were unchan ged. The result of the reorganization was the creation of the General Mills Pension Plan I (Plan I) and the 2005 Supplemental Retirement Plan I and the Supplemental Retirement Plan I (Grandfathered) (together, the Supplemental Plans I). The reorganizatio n was made to facilitate a targeted investment strategy over time and to provide additional flexibility in evaluating opportunities to reduce risk and volatility. Actuarial gains and losses associated with the Plan and the Supplemental Plans are amortized over the average remaining service life of the active participants. Actuarial gains and losses associated with the Plan I and the Supplemental Plans I are amortized over the average remaining life of the participants. Other Postretirement Benefit Plans We also sponsor plans that provide heal th care benefits to many 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 no voluntary contributions to these plans in fi scal 2019 or fiscal 2018 . Health Care Cost Trend Rates Assumed health care cost trends are as follows: Fiscal Year 2019 2018 Health care cost trend rate for next year 6.4% and 6.7% 6.7% and 7.0% Rate to which the cost trend rate is assumed to decline (ultimate rate) 4.5% 4.5% Year that the rate reaches the ultimate trend rate 2029 2029 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 6.7 percent for retirees age 65 and over and 6. 4 percent for retirees under age 65 at the end of fiscal 2019 . Rates are graded down annually until the ultimate trend rate of 4.5 percent is reached in 2029 for all retirees. The trend rates are applicable for calculations only if the retirees’ benefits increase as a result of health care infl ation. 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 2020 $ 1.4 $ (1.3) Effect on the other postretirement accumulated benefit obligation as of May 26, 2019 $ 43.5 $ (40.3) Postemployment Benefit Plans Under certain circumstances, we also provide accruable benefits, primarily severance, to former or inactive employees in the United States, Canada, and Mexico. 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.

Discount Rates We 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 utilizing a full yield curve approach by applying the specific spot rates along the yield curve used to determine the benefit obligation to the relevant projected cash flows. O ur discount rate assumptions are determined annually as of May 31 for our def ined benefit pension, other postretirement benefit, and postemployment benefit plan obligations. We also use discount rates as of May 31 to determine defined benefit pension, other postretirement benefit, 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, includ ing 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. Fair Value of Plan Assets The fair values of our pension and postretirement benefit plans’ assets and their respective levels in the fair value hierarchy by asset category were as follows: Fiscal Year 2019 Fiscal Year 2018 In Millions Level 1 Level 2 Level 3 Total Assets Level 1 Level 2 Level 3 Total Assets Fair value measurement of pension plan assets: Equity (a) $ 1,226.2 $ 664.6 $ - $ 1,890.8 $ 1,722.5 $ 782.1 $ - $ 2,504.6 Fixed income (b) 1,635.5 1,144.9 - 2,780.4 1,264.5 714.5 - 1,979.0 Real asset investments (c) 179.4 59.9 - 239.3 229.1 115.2 - 344.3 Other investments (d) - - 0.3 0.3 - - 0.3 0.3 Cash and accruals 186.5 - - 186.5 124.4 - - 124.4 Fair value measurement of pension plan assets $ 3,227.6 $ 1,869.4 $ 0.3 $ 5,097.3 $ 3,340.5 $ 1,611.8 $ 0.3 $ 4,952.6 Assets measured at net asset value (e) 1,194.3 1,224.8 Total pension plan assets (f) $ 6,291.6 $ 6,177.4 Fair value measurement of postretirement benefit plan assets: Equity (a) $ - $ 66.8 $ - $ 66.8 $ - $ 35.8 $ - $ 35.8 Fixed income (b) 139.7 241.4 - 381.1 241.0 123.6 - 364.6 Real asset investments (c) 0.3 - - 0.3 8.0 - - 8.0 Cash and accruals 11.1 - - 11.1 19.1 - - 19.1 Fair value measurement of postretirement benefit plan assets $ 151.1 $ 308.2 $ - $ 459.3 $ 268.1 $ 159.4 $ - $ 427.5 Assets measured at net asset value (e) 294.5 298.6 Total postretirement benefit plan assets (f) $ 753.8 $ 726.1 (a) Primarily publicly traded common stock 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 valued at unit values provided by the investment managers, which are based on the fair value of the underlying investments. (b) Primarily government and corporate debt securities and futures for purposes of total return, managing fixed income exposure to policy allocations, and duration targets. 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 valued at unit values provided by the investment managers, which are based on the fair value of the underlying investments. (d) Insurance and annuity contracts to provide a stable stream of income for pension retirees. Fair values are based on the fair value of the underlying investments and contract fair values established by the providers . (e) Primarily private investments, insurance contracts, and common collective trusts that are measured at fair value using the net asset value per share (or its equivalent) practical expedient and have not been classified in the fair value hierarchy. (f ) Plan assets and obligations are measured as of May 31, 2019, and May 31, 2018. There were no material changes in our level 3 i nvestments in fiscal 2019 and fiscal 2018 . 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 2019 2018 2019 2018 Asset category: United States equities 20.3 % 25.8 % 19.1 % 20.6 % International equities 12.5 16.1 11.2 10.7 Private equities 8.1 7.7 4.9 4.2 Fixed income 46.7 36.1 61.3 59.6 Real assets 12.4 14.3 3.5 4.9 Total 100.0 % 100.0 % 100.0 % 100.0 % 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. Fo r the U.S. defined benefit pension plans, the long-term investment policy allocation is: 18 percent to equities in the United States; 11 percent to international equities; 9 percent to private equities; 48 percent to fixed income; and 14 percent to real assets (real estate, energy, and infrastructure). For other U.S. postretirement benefit plans, the long-term investment policy allocations are: 18 percent to equities in the United States; 10 percent to international equities; 4 percent to private equities; 65 percen t to fixed income; and 3 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 2020 . Actual fiscal 2020 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 expe cted future service, as appropriate, are expe cte d to be paid from fiscal 2020 to 2029 as follows: In Millions Defined Benefit Pension Plans Other Postretirement Benefit Plans Gross Payments Medicare Subsidy Receipts Postemployment Benefit Plans 2020 $ 319.0 $ 52.4 $ 3.2 $ 20.1 2021 324.9 53.9 3.1 18.0 2022 331.8 55.7 2.9 16.6 2023 338.8 57.2 3.0 15.3 2024 346.3 56.9 3.1 14.3 2025-2029 1,856.4 282.4 15.7 59.6 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 $ 22.3 million as of May 26, 2019 , and $23.9 million as of May 27, 2018 . We also sponsor defined con tribution plans in many of our foreign locations. Our total recognized expense related to defined contribution plans was $ 52.7 million in fiscal 2019 , $ 49.2 million in fiscal 2018 , and $ 54.1 million in fiscal 2017 . We match a percentage of emp loyee 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 5.1 million as of May 26, 2019 , and 5.6 million as of May 27, 2018 . The ESOP’s only assets are our common stock and temporary cash balances. The Company stock fund and the ESOP collectively held $ 410.1 million and $392.1 million of Company common stock as of May 26, 2019 and May 27, 2018 , respectively.

The tax effects of temporary differences that give rise to deferred tax assets and liabilities are as follows: In Millions May 26, 2019 May 27, 2018 Accrued liabilities $ 50.9 $ 47.2 Compensation and employee benefits 196.6 210.2 Pension 103.2 57.1 Tax credit carryforwards 7.3 7.4 Stock, partnership, and miscellaneous investments 104.2 147.9 Capital losses 73.1 12.9 Net operating losses 141.7 161.2 Other 71.3 52.9 Gross deferred tax assets 748.3 696.8 Valuation allowance 213.7 176.0 Net deferred tax assets 534.6 520.8 Brands 1,472.6 1,498.7 Fixed assets 377.8 329.5 Intangible assets 259.7 255.1 Tax lease transactions 23.9 26.0 Inventories 39.0 38.8 Stock, partnership, and miscellaneous investments 330.0 317.1 Unrealized hedges 27.9 28.5 Other 34.7 30.9 Gross deferred tax liabilities 2,565.6 2,524.6 Net deferred tax liability $ 2,031.0 $ 2,003.8 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 cap ital gain income) within the carryforward period to allow us to realize these deferred tax benefits. Information about o ur valuation allowance follows: In Millions May 26, 2019 Pillsbury acquisition losses $ 108.2 State and foreign loss carryforwards 27.0 Capital loss carryforwards 73.0 Other 5.5 Total $ 213.7 As of May 26, 2019 , we believe it is more-likely-than-not that the remainder of our deferred tax assets are realizable. Information about our tax loss carryforwards follows: In Millions May 26, 2019 Foreign loss carryforwards $ 138.1 State operating loss carryforwards 12.5 Total tax loss carryforwards $ 150.6 Our foreign loss carryforwards expire as follows: In Millions May 26, 2019 Expire in fiscal 2020 and 2021 $ 3.4 Expire in fiscal 2022 and beyond 14.2 Do not expire 120.5 Total foreign loss carryforwards $ 138.1 On December 22, 2017, the 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 deeme d repatriation tax on untaxed foreign earnings. As a result of the TCJA, we recorded a provisional benefit of $523.5 million during fiscal 2018. During fiscal 2019, we completed our accounting for the tax effects of the TCJA and recorded a benefit of $ 7.2 million which included adjustments to the transition tax and the measurement of our net U.S. deferred tax liability. While our accounting for the recorded impact of the TCJA is deemed to be complete, these amounts were based on prevailing regulations and currently available information, and any additional guidance issued by the Internal Revenue Service ( IRS ) could impact the aforementioned amounts in future periods. The legislation also includes provisions that affected 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 minimum tax called the base erosion anti-abuse tax; a new provision that taxes U.S. allocated expenses as well as currently taxes certain income f rom foreign operations (Global Intangible Low Tax Income or GILTI); a new limitation on deductible interest expense; the repeal of the domestic manufacturing deduction; and limitations on the deductibility of certain executive compensation. While the ne w legislation generally eliminates U.S. federal income tax on dividends from foreign subsidiaries going forward, certain income earned by foreign subsidiaries must be included currently in our U.S. taxable income under the new GILTI inclusion rules. 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. In fiscal 2018, we made an accounting policy election to record these taxes a s a period cost. As of May 26, 2019, we have not recognized a deferred tax liability for unremitted earnings of approximately $ 2.3 billion from our foreign operations because we currently believe our subsidiaries have invested the undistributed earnings i ndefinitely, or the earnings will be remitted in a tax-neutral transaction. It is not practicable for us to determine the amount of unrecognized tax expense on these reinvested earnings. Deferred taxes are recorded for earnings of our foreign operations wh en we determine that such earnings are no longer indefinitely reinvested. As a result of the TCJA, we re-evaluated our assertion and have concluded that although earnings prior to fiscal 2018 will remain permanently reinvested, we will no longer make a pe rmanent reinvestment assertion beginning with our fiscal 2018 earnings. As part of the accounting for the TCJA, we recorded local country withholding taxes related to certain entities from which we began repatriating undistributed earnings and will continu e to record local country withholding taxes on all future earnings. In addition, in fiscal 2018, we adopted Accounting Standards Update 2018-02: Income Statement – Reporting Comprehensive Income (Topic 220) (ASU 2018-02), which provides the option to rec lassify stranded income tax effects resulting from the TCJA from 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 . 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 ta xes 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 va ry by jurisdiction, but are generally from 3 to 5 years. Several state and foreign examinations are currently in progress. We do not expect these examinations to result in a material impact on our results of operations or financial position. During f iscal 2018, we recorded an adjustment related to a prior year which increased income tax expense by $40.9 million. We determined the adjustment to be immaterial to our Consolidated Statements of Earnings for the fiscal year ended May 27, 2018. We have eff ectively settled all issues with the IRS for fiscal years 2015 and prior. During fiscal 2017, the Brazilian tax authority, Secretaria da Receita Federal do Brasil (RFB), concluded audits of our 2012 and 2013 tax return years. These audits included a review of our determinations of amortization of certain goodwill arising from the acquisition of Yoki Alimentos S.A . The RFB has proposed adjustments that effectively e liminate the goodwill amortization benefits related to this transaction. We believe we have meritorious defenses and intend to contest the disallowance. We apply a more-likely-than-not threshold to the recognition and derecognition of uncertain tax positi ons. 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 affe ct earnings in the period of such change. The following table sets forth changes in our total gross unrecognized tax benefit liabilities, excluding accrued interest, for fiscal 2019 and fiscal 2018 . Approximately $ 81.2 million of this total in fisc al 2019 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 defer red taxes if recognized. We also would record a decrease in U.S. federal income taxes upon recognition of the state tax benefits included therein. Fiscal Year In Millions 2019 2018 Balance, beginning of year $ 196.3 $ 135.5 Tax positions related to current year: Additions 19.5 24.1 Reductions (0.1) - Tax positions related to prior years: Additions 3.8 54.8 Reductions (13.2) (7.9) Settlements (41.0) (3.9) Lapses in statutes of limitations (26.2) (6.3) Balance, end of year $ 139.1 $ 196.3 As of May 26, 2019 , we expect to pay approximately $ 2.0 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 i nterest and penalties related to unrecognized tax benefit liabilities in income tax expense. For fiscal 2019 , we recognized $ 0.5 million of tax-related net interest and penalties, and had $ 26.0 million of accrued interest and penalties as of May 26, 2019 . For fis cal 2018 , we recognized a net benefit of $ 3 . 1 million of tax-related net inter est and penalties, and had $ 2 7 . 3 million of accrued interest and penalties as of May 27, 2018 .

Our product categories include dog and cat food (dry foods, wet foods, and treats) made with whole meats, fruits , and vegetables and other high-quality natural ingredients. Our tailored pet product offerings address specif ic dietary, lifestyle, and life-stage needs and span different product types, diet types, breed sizes for dogs, lifestages, flavors, product functions and textures, and cuts for wet foods. We are reporting the Pet operating segment results on a one-month l ag and accordingly, our fiscal 2018 results did not include Pet segment operating results. Operating profit for these segments excludes unallocated corporate items, gain or loss on divestitures, 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, asset and liability remeasurement impact of hyperinflationary economies, 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 positions until passed back to our operating segments. These items affe cting 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 [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 are valued at net realizable value, and all related cash contracts and derivatives are valued at fair value, 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 net realizable value. 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 ac cepted 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 u sually depreciated over 40 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 26, 2019 , assets h eld 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 e stimated 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. We perform our annual goodwill and indefinite-lived intangible assets impairment test as of the first day of the second quarter of the fiscal year. 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, impairment has occurred . We recognize an impairment charge for the amount by which the carrying amount o f the reporting unit exceeds it s fair value up to the total amount of goodwill allocated to the reporting unit. Our estimates of fair value are determined based on a discounte d 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, competit ion, 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 main tenance 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 Blue Buffalo , Pillsbury , Totino’s , Yoplait , Old El Paso , Progresso , Annie’s , Hä agen-Dazs , and Yoki brands, are also tested for impairment annually and whenever events or change s in circumstances indicate that their carrying value may not be recoverable. Our estimate of the fair value of the brands is 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 whene ver 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 Unconsolidated Joint Ventures and Redeemable Interest	Investments in Unconsolidated 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, as a result of ongoing operating losses, projected decreases in earnings, increases in the weighted - average cost of capital, or significant business disruptions. The significant assumptions used to estimat e 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 conclude d the impairment is othe r than temporary. Redeemable Interest We have a 51 percent control ling interest in Yoplait SAS , a consolidated entity. Sodiaal International (Sodiaal) holds the remaining 49 pe rcent interest in Yoplait SAS. 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 . 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 th e 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 c apital on our Consolidated Balance Sheets quarterly to the redeemable interest’s redemption value, which approximates its fair value. During the second and fourth quarters of fiscal 2019 , we adjusted the redeemable interest’s redemption value based on a disco unted 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 exchange rates, and a discount rat e.
Revenue Recognition	Revenue Recognition
Environmental	Our revenues primarily result from contracts with customers, which are generally short-term and have a single performance obligation – the delivery of product. We recognize revenue for the sale of packaged foods at the point in time when our performance ob ligation has been satisfied and control of the product has transferred to our customer, which generally occurs when the shipment is accepted by our customer. Sales include shipping and handling charges billed to the customer and are reported net of variabl e consideration and consideration payable to our customers, including trade promotion, consumer coupon redemption and other costs, including estimated allowances for returns, unsalable product, and prompt pay discounts. Sales, use, value-added, and other e xcise taxes are not included in revenue. Trade promotions are recorded using significant judgment of estimated participation and performance levels for offered programs at the time of sale. Differences between estimated expenses and actual costs are recogn ized as a change in management estimate in a subsequent period. 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. Payment terms and collection patterns are short-term, and vary around the world and by channel, and as such, we do not have any signif icant financing components. Our 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 ba lances are written off against the allowance when we deem the amount is uncollectible. Please see Note 16 for a disaggregation of our revenue into categories that depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. We do not have material contract assets or liabilities arising from our contracts with customers. Environmenta l Costs Environmental costs relating to existing conditions caused by past operations that do not contribute to current or futur e 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 actio n.
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 period incu rred. R&D includes expenditures for new product and manufacturing process innovation, and the annual expenditures are comprised primarily of internal salari es, wages, consulting, and supplies attributable to 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 exchan ge rates prevailing during the period . Translation adjustments are reflected within accumula ted 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 f oreign exchange gains and losses on instruments designated as net investment hedges. These gains and losses are recorded in AOCI .
Derivative Instruments	Derivative Instruments All d erivatives are recognized on our Consolidated Balance Sheets at fair value based on quoted marke t 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 whe ther 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 compensa tion expense for grants of restricted stock units and performance share units using the value of a share of our stock on the date of grant. We estimate the value of stoc k option grants using a Black- Scholes valuation model. Generally, s tock -based compensat ion is recognized straight line over the vesting period. Our stock -based compensation expense is recorded in selling, general and administrative ( SG&A ) expenses and cost of sales in our Consolidated Statements of Earnings and allocated to each reportable s egment 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 generally recogniz ed 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 recog nized compensation cost as an operating cash flow .
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 be nefits to retired employees. Under certain circumstances, we also provide accruable benefits , primarily severance, to former or inactive employees in the United States , Canada , and Mexico. 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 . In fiscal 2018, we approved an amendment to reorga nize the U.S. qualified defined benefit pension plans and the supplemental pension plans that resulted in the spinoff of a portion of the General Mills Pension Plan (the Plan) and the 2005 Supplemental Retirement Plan and the Supplemental Retirement Plan ( Grandfathered) (together, the Supplemental Plans) into new plans effective May 31, 2018. The benefits offered to the plans’ participants were unchanged. The result of the reorganization was the creation of the General Mills Pension Plan I (Plan I) and th e 2005 Supplemental Retirement Plan I and the Supplemental Retirement Plan I (Grandfathered) (together, the Supplemental Plans I). The reorganization was made to facilitate a targeted investment strategy over time and to provide additional flexibility in evaluating opportunities to reduce risk and volatility. Actuarial gains and losses associated with the Plan and the Supplemental Plans are amortized over the average remaining service period of the active participants. Actuarial gains and losses associat ed with the Plan I and the Supplemental Plans I are amortized over the average remaining life of the participants. Please refer to Note 13 for a description of our defined benefit pension, other postretirement benefit, and postemployment benefit plans.
Use of Estimates	U se 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, disclosu res 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 as sets, intangible assets, redeemable interest, stock-based compensation, income taxes, and defined benefit pension, other p ostretirement benefit and postemployment benefit plans . Actual results could differ from our estimates.
Other New Accounting Standards	New Accounting Standards In the first quarter of fiscal 2019, we adopted new accounting requirements related to the presentation of net periodic defined benefit pension expense, net periodic postretirement benefit expense, and net periodic postemployment benefit expense (collectively “net periodic benefit expense”). The new standard requires the service cost component of net periodic benefit expense to be recorded in the same line items as other employee compensation costs within our Consoli dated Statements of Earnings. Other components of net periodic benefit expense must be presented separately outside of operating profit in our Consolidated Statements of Earnings. In addition, the new standard requires that only the service cost component of net periodic benefit expense is eligible for capitalization. The new standard requires retrospective adoption of the presentation of net periodic benefit expense and prospective application of the capitalization of the service cost component. The impact of the adoption of this standard on our results of operations was a decrease to our operating profit of $87.9 million, $89.4 million and $74.3 million and a corresponding increase to benefit plan non-service income of $87.9 million, $89.4 million and $74. 3 million for fiscal 2019, fiscal 2018 and fiscal 2017, respectively. There were no changes to our reported segment operating profit. In the first quarter of fiscal 2019, we adopted new accounting requirements for the recognition of revenue from contracts with customers. Under the new standard, we apply a principles-based five step model to recognize revenue upon the transfer of control of promised goods to customers and in an amount that reflects the consideration for which we expect to be entitled to in exchange for those goods. The principles-based five step model includes: 1) identifying the contract(s) with a customer; 2) identifying the performance obligations in the contract; 3) determining the transaction price; 4) allocating the transaction price t o the performance obligations in the contract; and 5) recognizing revenue when (or as) we satisfy a performance obligation. We utilized a comprehensive approach to evaluate and document the impact of the guidance on our current accounting policies and prac tices. We did not identify any material differences resulting from applying the new requirements to our revenue contracts. Additionally, we did not identify any significant changes to our business processes, systems, and controls to support recognition and disclosure requirements under the new guidance. We adopted the requirements of the new standard and subsequent amendments to all contracts in the first quarter of fiscal 2019 using the cumulative effect approach. We recorded a $33.9 million cumulative eff ect adjustment net of income tax effects to the opening balance of fiscal 2019 retained earnings, a decrease to deferred income taxes of $11.4 million, and an increase to other current liabilities of $45.3 million related to the timing of recognition of ce rtain promotional expenditures. In the third quarter of fiscal 2018, we adopted new accounting requirements that codify Securities and Exchange Commission (SEC) Staff Accounting Bulletin No. 118, as it relates to allowing for recognition of provisional am ounts related to the U.S. Tax Cuts and Jobs Act (TCJA) in the event that the accounting is not complete and a reasonable estimate can be made. Where necessary information is not available, prepared, or analyzed to determine a reasonable estimate, no provis ional amount should be recorded. The guidance allows for a measurement period of up to one year from the enactment date to finalize the accounting related to the TCJA. In fiscal 2019, we completed our accounting for the tax effects of the TCJA. In the thi rd quarter of fiscal 2018, we adopted new accounting requirements that provide the option to reclassify stranded income tax effects resulting from the TCJA from 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 consisted of deferred taxes originally recorded in AOCI that exceeded the newly enacted federal corporate tax rate. The new accounting requirements allowed for adjustments to reclassi fication amounts in subsequent periods as a result of changes to the provisional amounts recorded. 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 r esulted 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 retrospectively adopted the guidance related to reclassification of realized windfall tax benefits , which resulted in reclassifications of cash provided by financing activities to operating activities in our Consolidated Statements of Cash Flow s. Additionally, we retrospectively adopted the guidance related to reclassification of employee tax withholdings , which resulted in reclassifications of cash used by operating activities to financing activities in our Consolidated Statements of Cash Flows . Stock-based compensation expense continues to reflect estimated forfeitures. In the first quarter of fiscal 2018, we adopted new accounting requirements which permit reporting entities to measure a goodwill impairment loss by the amount by which a report ing unit’s carrying value exceeds the reporting unit’s fair value. Previously, goodwill impairment 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 results of operations or financial position. In the first quarter of fiscal 2017, we adopted new accounting requirements for the presentation of certain investments using the net asset value, providing a practical expedient to exclude such investments from categorization within the fair value hierarchy and separate disclosure. We adopted the guidance retrospectively and restated the fiscal 2016 fair value of plan asset tables in Note 13. The adoption of this guidance did not impact our results of operations or financial position. In the first quarter of fiscal 2017, we adopted new accounting requirements which permit reporting entities with a fiscal year -end that does not coincide with a month-end to apply a practical expedient that permits the entity to measure defined benefit plan assets and obligations using the month-end that is closest to the entity’s fiscal year-end and apply such practical expedien t consistently to all plans. The adoption of this guidance did not have a material impact on our results of operations or financial position.

Share-based Compensation Arrangement by Share-based Payment Award [Line Items]
Number of shares available for grant under stock compensation plan	30.3
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, dividend yield, and the forfeiture rate. 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.
