SUMMARY OF SIGNIFICANT ACCOUNTI

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The unaudited financial information reflects all adjustments, which are, in the opinion of management, necessary for a fair presentation of the results of operations, financial position, and cash flows for the periods presented. The adjustments are of a normal recurring nature, except as otherwise noted. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the ConAgra Foods, Inc. (the "Company", "we", "us", or "our") Annual Report on Form 10-K for the fiscal year ended May 29, 2016 . The results of operations for any quarter or a partial fiscal year period are not necessarily indicative of the results to be expected for other periods or the full fiscal year. Basis of Consolidation — The condensed consolidated financial statements include the accounts of ConAgra Foods, Inc. and all majority-owned subsidiaries. In addition, the accounts of all variable interest entities for which we have been determined to be the primary beneficiary are included in our condensed consolidated financial statements from the date such determination is made. All significant intercompany investments, accounts, and transactions have been eliminated. Comprehensive Income — Comprehensive income includes net income, currency translation adjustments, certain derivative-related activity, changes in the value of available-for-sale investments, and changes in prior service cost and net actuarial gains (losses) from pension (for amounts not in excess of the 10% corridor) and post-retirement health care plans. We generally deem our foreign investments to be essentially permanent in nature and we do not provide for taxes on currency translation adjustments arising from converting the investment denominated in a foreign currency to U.S. dollars. When we determine that a foreign investment, as well as undistributed earnings, are no longer permanent in nature, estimated taxes are provided for the related deferred tax liability (asset), if any, resulting from currency translation adjustments. The following table summarizes the reclassifications from accumulated other comprehensive income (loss) into operations: Thirteen Weeks Ended Affected Line Item in the Condensed Consolidated Statement of Operations August 28, 2016 August 30, 2015 Amortization of pension and postretirement liabilities: Net prior service benefit $ (0.9 ) $ (1.3 ) Selling, general and administrative expenses (0.9 ) (1.3 ) Total before tax 0.3 0.5 Income tax expense $ (0.6 ) $ (0.8 ) Net of tax Reclassifications and other changes — Certain prior year amounts have been reclassified to conform with current year presentation. Use of Estimates — Preparation of financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") requires management to make estimates and assumptions. These estimates and assumptions affect reported amounts of assets, liabilities, revenues, and expenses as reflected in the condensed consolidated financial statements. Actual results could differ from these estimates. Accounting Changes — In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-09, Improvements to Employee Share-Based Payment Accounting, which simplifies the accounting for income taxes, among other changes, related to stock-based compensation. We elected to early adopt this ASU as of the beginning of fiscal 2017. For the first quarter of fiscal 2017, we recognized all excess tax benefits and tax deficiencies as income tax expense or benefit as a discrete event. An income tax benefit of approximately $11.6 million was recognized in the first quarter of fiscal 2017 as a result of the adoption of ASU 2016-09. The treatment of forfeitures has changed as we have elected to discontinue our past process of estimating the number of forfeitures and now account for forfeitures as they occur. As such, this had a cumulative effect on retained earnings of $3.9 million , net of tax. We have elected to present the cash flow statement on a retrospective transition method and prior periods have been adjusted to present the excess tax benefits as part of cash flows from operating activities. This resulted in an increase in cash flows from operating activities and a decrease in cash flows from financing activities of $26.3 million in the first quarter of fiscal 2016. Recently Issued Accounting Standards — In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP. On July 9, 2015, the FASB deferred the effective date of the new revenue recognition standard by one year. Based on the FASB’s ASU, we will apply the new revenue standard in our fiscal year 2019. Early adoption in our fiscal year 2018 is permitted. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. The standard permits the use of either the retrospective or cumulative effect transition method. In July 2015, the FASB issued ASU 2015-11, Inventory , which requires an entity to measure inventory within the scope at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The effective date for the standard is for fiscal years beginning after December 15, 2016. Early adoption is permitted. The standard is to be applied prospectively. We do not expect ASU 2015-11 to have a material impact to our financial statements. In February 2016, the FASB issued its final lease accounting standard, FASB Accounting Standard Codification ("ASC") Topic 842, Leases , which requires lessees to reflect most leases on their balance sheet as assets and obligations. The effective date for the standard is for fiscal years beginning after December 15, 2018. Early adoption is permitted. We are evaluating the effect that ASC 842 will have on our consolidated financial statements and related disclosures. The standard is to be applied under the modified retrospective method, with elective reliefs, which requires application of the new guidance for all periods presented.

DISCONTINUED OPERATIONS AND OTHER DIVESTITURES	DISCONTINUED OPERATIONS AND OTHER DIVESTITURES Private Brands Operations On February 1, 2016, pursuant to the Stock Purchase Agreement, dated as of November 1, 2015, we completed the disposition of our Private Brands operations to TreeHouse Foods, Inc. ("Treehouse") for $2.6 billion in cash on a debt-free basis, subject to working capital and other adjustments. As a result of the disposition, we recognized a pre-tax charge of $1.81 billion ( $1.34 billion after-tax) in the first quarter of fiscal 2016, to write-down the goodwill and long-lived assets to the estimated sales price, less costs to sell. We reflected the results of this business as discontinued operations for all periods presented. The summary comparative financial results of the Private Brands business, included within discontinued operations, were as follows: Thirteen weeks ended August 28, 2016 August 30, 2015 Net sales $ — $ 891.8 Gain on sale of businesses $ 1.5 $ — Goodwill and long-lived asset impairment charges — (1,812.3 ) Income (loss) from operations of discontinued operations before income taxes and equity method investment earnings (0.7 ) 20.4 Income (loss) before income taxes 0.8 (1,791.9 ) Income tax benefit (0.7 ) (472.1 ) Income (loss) from discontinued operations, net of tax $ 1.5 $ (1,319.8 ) Other Divestitures During the first quarter of fiscal 2017, we completed the sales of our Spicetec Flavors & Seasonings business ("Spicetec") and our JM Swank business, parts of our Commercial segment, for $327.0 million and $159.3 million , respectively, in cash, net of cash included in the dispositions. We recognized a gain from the sales of $145.0 million and $53.2 million , respectively. The assets and liabilities of these businesses have been reclassified as assets and liabilities held for sale within our Condensed Consolidated Balance Sheets for the period presented prior to the divestiture. The assets and liabilities classified as held for sale reflected in our Condensed Consolidated Balance Sheets related to the Spicetec and JM Swank businesses were as follows: May 29, 2016 Spicetec: Current assets $ 43.3 Noncurrent assets (including goodwill of $104.7 million) 148.3 Current liabilities 10.3 Noncurrent liabilities 1.2 Swank: Current assets $ 73.7 Noncurrent assets (including goodwill of $53.8 million) 74.3 Current liabilities 44.3 Noncurrent liabilities 0.4 In addition, we are actively marketing certain other long-lived assets. These assets have been reclassified as assets held for sale within our Condensed Consolidated Balance Sheets for all periods presented. These assets were held within our Corporate and Grocery & Snacks segments, respectively. The balance of these noncurrent assets classified as held for sale was $5.8 million and $6.9 million at August 28, 2016 and May 29, 2016 , respectively.

Restructuring and Related Activities [Abstract]
RESTRUCTURING ACTIVITIES	RESTRUCTURING ACTIVITIES Supply Chain and Administrative Efficiency Plan We previously announced a plan for the integration and restructuring of the operations of Ralcorp Holdings, Inc. ("Ralcorp"), optimization of the entire Company's supply chain network, manufacturing assets, and dry distribution and mixing centers, and improvement of selling, general and administrative effectiveness and efficiencies, which we refer to as the Supply Chain and Administrative Efficiency Plan (the "SCAE Plan"). Although the divestiture of the Private Brands business was completed in the third quarter of fiscal 2016, we will continue to implement portions of the SCAE Plan, including work related to optimizing our supply chain network and pursue cost reductions through our selling, general and administrative functions and productivity improvements. The SCAE Plan also includes plans announced in the second quarter of fiscal 2016 to realize efficiency benefits through a combination of reductions in selling, general and administrative expenses and enhancements to trade spend processes and tools. Although we remain unable to make good faith estimates relating to the entire SCAE Plan, we are reporting on actions initiated through the end of the first quarter of fiscal 2017 , including the estimated amounts or range of amounts for each major type of costs expected to be incurred, and the charges that have resulted or will result in cash outflows. As of August 28, 2016 , our Board of Directors has approved the incurrence of up to $739.0 million of expenses in connection with the SCAE Plan, including expenses allocated for the Private Brands operations. We have incurred or expect to incur approximately $431.4 million of charges ( $300.4 million of cash charges and $131.0 million of non-cash charges) for actions identified to date under the SCAE Plan related to our continuing operations. In the first quarter of fiscal 2017 and 2016 , we recognized charges of $14.1 million and $17.4 million , respectively, in relation to the SCAE Plan related to our continuing operations. We expect to incur costs related to the SCAE Plan over a multi-year period. We anticipate that we will recognize the following pre-tax expenses in association with the SCAE Plan related to our continuing operations (amounts include charges recognized from plan inception through the first quarter of fiscal 2017 ): Grocery & Snacks Refrigerated & Frozen International Foodservice Commercial Corporate Total Multi-employer pension costs $ 29.8 $ 1.5 $ — $ — $ — $ — $ 31.3 Accelerated depreciation 31.6 19.0 — — — 1.2 51.8 Other cost of goods sold 5.6 2.6 — — — — 8.2 Total cost of goods sold 67.0 23.1 — — — 1.2 91.3 Severance and related costs, net 21.9 12.1 4.2 6.1 2.1 97.7 144.1 Fixed asset impairment (Net of gains on disposal) 7.3 6.2 — — — 0.8 14.3 Accelerated depreciation — 0.1 — — — 1.5 1.6 Contract/Lease cancellation expenses (recoveries) 0.8 0.5 — — — 61.8 63.1 Consulting/Professional fees 0.6 0.4 0.1 — — 57.5 58.6 Other selling, general and administrative expenses 11.8 3.8 — — — 42.8 58.4 Total selling, general and administrative expenses 42.4 23.1 4.3 6.1 2.1 262.1 340.1 Consolidated total $ 109.4 $ 46.2 $ 4.3 $ 6.1 $ 2.1 $ 263.3 $ 431.4 During the first quarter of fiscal 2017 , we recognized the following pre-tax expenses for the SCAE Plan related to our continuing operations: Grocery & Snacks Refrigerated & Frozen International Foodservice Commercial Corporate Total Accelerated depreciation $ 1.8 $ 1.2 $ — $ — $ — $ — $ 3.0 Other cost of goods sold 2.0 0.2 — — — — 2.2 Total cost of goods sold 3.8 1.4 — — — — 5.2 Severance and related costs, net (0.2 ) — 0.2 1.8 — — 1.8 Fixed asset impairment (Net of gains on disposal) 0.6 2.6 — — — — 3.2 Accelerated depreciation — — — — — 0.2 0.2 Contract/Lease cancellation expenses (recoveries) — — — — — (1.5 ) (1.5 ) Consulting/Professional fees — — — — — 0.1 0.1 Other selling, general and administrative expenses 0.7 1.0 — — — 3.4 5.1 Total selling, general and administrative expenses 1.1 3.6 0.2 1.8 — 2.2 8.9 Consolidated total $ 4.9 $ 5.0 $ 0.2 $ 1.8 $ — $ 2.2 $ 14.1 Included in the above table are $5.5 million of charges that have resulted or will result in cash outflows and $8.6 million in non-cash charges.

During the third quarter of fiscal 2016, we repaid the entire principal balance of $750.0 million of our 1.30% senior notes on the maturity date of January 25, 2016. The repayment was primarily funded through the issuance of term loans totaling $600.0 million which were repaid in the third quarter of fiscal 2016 with the proceeds from the divestiture of our Private Brands business. During the third quarter of fiscal 2016, Lamb Weston BSW (See Note 5) issued a $30.0 million promissory note with a financial institution. The note includes a $23.0 million fixed rate loan segment with interest at 4.34% and a $7.0 million variable rate loan segment with interest at LIBOR plus an applicable margin ranging from 1.90% to 2.30% , payable in semi-annual installments through fiscal 2032. During the second quarter of fiscal 2016, we repaid the entire principal balance of $250.0 million of our 1.35% senior notes on the maturity date of September 10, 2015. Net interest expense from continuing operations consists of: Thirteen weeks ended August 28, August 30, Long-term debt $ 61.5 $ 82.3 Short-term debt 0.5 0.2 Interest income (0.8 ) (0.2 ) Interest capitalized (2.2 ) (2.0 ) $ 59.0 $ 80.3

Variable Interest Entity, Measure of Activity [Abstract]
VARIABLE INTEREST ENTITIES	VARIABLE INTEREST ENTITIES Variable Interest Entities Consolidated We own a 49.99% interest in Lamb Weston BSW, LLC ("Lamb Weston BSW"), a potato processing venture with Ochoa Ag Unlimited Foods, Inc. ("Ochoa"). We provide all sales and marketing services to Lamb Weston BSW. Under certain circumstances, we could be required to compensate Ochoa for lost profits resulting from significant production shortfalls ("production shortfalls"). Commencing on June 1, 2018, or on an earlier date under certain circumstances, we have a contractual right to purchase the remaining equity interest in Lamb Weston BSW from Ochoa (the "call option"). We are currently subject to a contractual obligation to purchase all of Ochoa's equity investment in Lamb Weston BSW at the option of Ochoa (the "put option"). The purchase prices under the call option and the put option (the "options") are based on the book value of Ochoa's equity interest at the date of exercise, as modified by an agreed-upon rate of return for the holding period of the investment balance. The agreed-upon rate of return varies depending on the circumstances under which any of the options are exercised. As of August 28, 2016 , the price at which Ochoa had the right to put its equity interest to us was $48.9 million . This amount is presented within other noncurrent liabilities in our Condensed Consolidated Balance Sheets. We have determined that Lamb Weston BSW is a variable interest entity and that we are the primary beneficiary of the entity. Accordingly, we consolidate the financial statements of Lamb Weston BSW. During the third quarter of fiscal 2016, Lamb Weston BSW issued a $30.0 million promissory note with a financial institution. The note includes a $23.0 million fixed rate loan segment with interest at 4.34% and a $7.0 million variable rate loan segment with interest at LIBOR plus an applicable margin ranging from 1.90% to 2.30% , payable in semi-annual installments through fiscal 2032. Lamb Weston BSW also issued a $10.0 million revolving note with interest at LIBOR plus an applicable margin ranging from 1.75% to 2.00% that matures in June 2021. As of August 28, 2016, Lamb Weston BSW had $1.0 million outstanding against this revolving note. In connection with these Lamb Weston BSW financings, Lamb Weston has entered into an agreement with the financial institution which provides that in the event that Lamb Weston BSW fails to comply with certain financial covenants or repayment terms, Lamb Weston is required to either make certain additional equity contributions to Lamb Weston BSW or to purchase the underlying notes. Our variable interests in Lamb Weston BSW include an equity investment in the venture, the options, certain fees paid to us by Lamb Weston BSW for sales and marketing services, and the contingent obligation related to production shortfalls. Our maximum exposure to loss as a result of our involvement with this venture is equal to our equity investment in the venture, the balance of any promissory notes extended to the venture which are subject to Lamb Weston’s purchase obligation, and the amount, if any, by which the put option exercise price exceeds the fair value of the noncontrolling interest in Lamb Weston BSW upon its exercise. Also, in the event of a production shortfall, we could be required to compensate Ochoa for lost profits. It is not possible to determine the maximum exposure to losses from the potential exercise of the put option or from potential production shortfalls. However, we do not expect to incur material losses resulting from these potential exposures. Due to the consolidation of this variable interest entity, we reflected the following in our Condensed Consolidated Balance Sheets: August 28, May 29, Cash and cash equivalents $ 9.1 $ 4.3 Receivables, less allowance for doubtful accounts 0.1 0.1 Inventories 1.4 1.2 Prepaid expenses and other current assets 0.3 0.4 Property, plant and equipment, net 51.4 52.2 Goodwill 18.8 18.8 Brands, trademarks and other intangibles, net 5.0 5.2 Total assets $ 86.1 $ 82.2 Notes payable $ 1.0 $ 1.0 Current installments of long-term debt 1.2 0.5 Accounts payable 13.5 10.9 Accrued payroll 0.6 0.8 Other accrued liabilities 1.3 0.9 Senior long-term debt, excluding current installments 28.8 29.5 Other noncurrent liabilities (noncontrolling interest) 33.2 32.2 Total liabilities $ 79.6 $ 75.8 The liabilities recognized as a result of consolidating the Lamb Weston BSW entity do not represent additional claims on our general assets. The creditors of Lamb Weston BSW have claims only on the assets of Lamb Weston BSW. The assets recognized as a result of consolidating Lamb Weston BSW are the property of the venture and are not available to us for any other purpose. Variable Interest Entities Not Consolidated We also have variable interests in certain other entities that we have determined to be variable interest entities, but for which we are not the primary beneficiary. We do not consolidate the financial statements of these entities. We hold a 50% interest in Lamb Weston RDO, a potato processing venture. We provide all sales and marketing services to Lamb Weston RDO. We receive a fee for these services based on a percentage of the net sales of the venture. We reflect the value of our ownership interest in this venture in other assets in our Condensed Consolidated Balance Sheets, based upon the equity method of accounting. The balance of our investment was $17.1 million and $16.9 million at August 28, 2016 and May 29, 2016 , respectively, representing our maximum exposure to loss as a result of our involvement with this venture. The capital structure of Lamb Weston RDO includes owners' equity of $34.3 million and term borrowings from banks of $40.5 million as of August 28, 2016 . We have determined that we do not have the power to direct the activities that most significantly impact the economic performance of this venture. We lease certain office buildings from entities that we have determined to be variable interest entities. The lease agreements with these entities include fixed-price purchase options for the assets being leased. The lease agreements also contain contingent put options (the “lease put options”) that allow the lessors to require us to purchase the buildings at the greater of original construction cost, or fair market value, without a lease agreement in place (the “put price”) in certain limited circumstances. As a result of substantial impairment charges related to our divested Private Brands operations, these lease put options are exercisable now and remain exercisable until generally 30 days after the end of the respective lease agreements. We are amortizing the difference between the estimated put price and the estimated fair value (without a lease agreement in place) of each respective property over the remaining respective lease term within selling, general and administrative expenses. As of August 28, 2016 , the estimated amount by which the put prices exceeded the fair values of the related properties was $58.5 million , of which we have accrued $11.1 million . As these buildings are worth considerably more when under lease agreements than when vacant, we may be able to mitigate some, or all of the financial exposure created by the put options by maintaining active lease agreements and/or by subleasing the buildings to credit worthy tenants. We do not expect to ultimately incur material financial losses as a result of the potential exercise of the lease put options by the lessors. These leases are accounted for as operating leases, and accordingly, there are no material assets or liabilities, other than the accrued portion of the put price, associated with these entities included in our Condensed Consolidated Balance Sheets. We have determined that we do not have the power to direct the activities that most significantly impact the economic performance of these entities. In making this determination, we have considered, among other items, the terms of the lease agreements, the expected remaining useful lives of the assets leased, and the capital structure of the lessor entities.

See further discussion in "Critical Accounting Estimates" in Management's Discussion and Analysis. Non-amortizing intangible assets are comprised of brands and trademarks. Amortizing intangible assets, carrying a remaining weighted average life of approximately 15 years , are principally composed of customer relationships, licensing arrangements, and intellectual property. Based on amortizing assets recognized in our Condensed Consolidated Balance Sheet as of August 28, 2016 , amortization expense is estimated to average $35.9 million for each of the next five years. In the first quarter of fiscal 2016, we recorded an amortizing intangible asset of $92.8 million , of which only $14.9 million and $10.4 million was a cash payment made in the first quarter of fiscal 2017 and fiscal 2016, respectively. Remaining payments will be made over a five -year period.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS Our operations are exposed to market risks from adverse changes in commodity prices affecting the cost of raw materials and energy, foreign currency exchange rates, and interest rates. In the normal course of business, these risks are managed through a variety of strategies, including the use of derivatives. Commodity and commodity index futures and option contracts are used from time to time to economically hedge commodity input prices on items such as natural gas, vegetable oils, proteins, packaging materials, dairy, grains, and electricity. Generally, we economically hedge a portion of our anticipated consumption of commodity inputs for periods of up to 36 months. We may enter into longer-term economic hedges on particular commodities, if deemed appropriate. As of August 28, 2016 , we had economically hedged certain portions of our anticipated consumption of commodity inputs using derivative instruments with expiration dates through April 2017. In order to reduce exposures related to changes in foreign currency exchange rates, we enter into forward exchange, option, or swap contracts from time to time for transactions denominated in a currency other than the applicable functional currency. This includes, but is not limited to, hedging against foreign currency risk in purchasing inventory and capital equipment, sales of finished goods, and future settlement of foreign-denominated assets and liabilities. As of August 28, 2016 , we had economically hedged certain portions of our foreign currency risk in anticipated transactions using derivative instruments with expiration dates through May 2017. From time to time, we may use derivative instruments, including interest rate swaps, to reduce risk related to changes in interest rates. This includes, but is not limited to, hedging against increasing interest rates prior to the issuance of long-term debt and hedging the fair value of our senior long-term debt. Economic Hedges of Forecasted Cash Flows Many of our derivatives do not qualify for, and we do not currently designate certain commodity or foreign currency derivatives to achieve, hedge accounting treatment. We reflect realized and unrealized gains and losses from derivatives used to economically hedge anticipated commodity consumption and to mitigate foreign currency cash flow risk in earnings immediately within general corporate expense (within cost of goods sold). The gains and losses are reclassified to segment operating results in the period in which the underlying item being economically hedged is recognized in cost of goods sold. In the event that management determines a particular derivative entered into as an economic hedge of a forecasted commodity purchase has ceased to function as an economic hedge, we cease recognizing further gains and losses on such derivatives in corporate expense and begin recognizing such gains and losses within segment operating results, immediately. Economic Hedges of Fair Values — Foreign Currency Exchange Rate Risk We may use options and cross currency swaps to economically hedge the fair value of certain monetary assets and liabilities (including intercompany balances) denominated in a currency other than the functional currency. These derivatives are marked-to-market with gains and losses immediately recognized in selling, general and administrative expenses. These substantially offset the foreign currency transaction gains or losses recognized as values of the monetary assets or liabilities being economically hedged change. All derivative instruments are recognized on our balance sheets at fair value (refer to Note 15 for additional information related to fair value measurements). The fair value of derivative assets is recognized within prepaid expenses and other current assets, while the fair value of derivative liabilities is recognized within other accrued liabilities. In accordance with U.S. GAAP, we offset certain derivative asset and liability balances, as well as certain amounts representing rights to reclaim cash collateral and obligations to return cash collateral, where master netting agreements provide for legal right of setoff. At August 28, 2016 and May 29, 2016 , amounts representing a right to reclaim cash collateral of $0.3 million were included in prepaid expenses and other current assets in our Condensed Consolidated Balance Sheets. Derivative assets and liabilities and amounts representing a right to reclaim cash collateral or an obligation to return cash collateral were reflected in our Condensed Consolidated Balance Sheets as follows: August 28, May 29, Prepaid expenses and other current assets $ 23.1 $ 26.1 Other accrued liabilities 0.4 0.7 The following table presents our derivative assets and liabilities, at August 28, 2016 , on a gross basis, prior to the setoff of $3.4 million to total derivative assets and $3.7 million to total derivative liabilities where legal right of setoff existed: Derivative Assets Derivative Liabilities Balance Sheet Location Fair Value Balance Sheet Location Fair Value Commodity contracts Prepaid expenses and other current assets $ 6.5 Other accrued liabilities $ 3.8 Foreign exchange contracts Prepaid expenses and other current assets 19.9 Other accrued liabilities — Other Prepaid expenses and other current assets 0.1 Other accrued liabilities 0.3 Total derivatives not designated as hedging instruments $ 26.5 $ 4.1 The following table presents our derivative assets and liabilities at May 29, 2016 , on a gross basis, prior to the setoff of $1.8 million to total derivative assets and $2.1 million to total derivative liabilities where legal right of setoff existed: Derivative Assets Derivative Liabilities Balance Sheet Location Fair Value Balance Sheet Location Fair Value Commodity contracts Prepaid expenses and other current assets $ 6.5 Other accrued liabilities $ 2.3 Foreign exchange contracts Prepaid expenses and other current assets 21.4 Other accrued liabilities 0.2 Other Prepaid expenses and other current assets — Other accrued liabilities 0.3 Total derivatives not designated as hedging instruments $ 27.9 $ 2.8 The location and amount of gains (losses) from derivatives not designated as hedging instruments in our Condensed Consolidated Statements of Operations were as follows: Derivatives Not Designated as Hedging Instruments Location in Condensed Consolidated Statement of Operations of Gain (Loss) Recognized on Derivatives Amount of Gain (Loss) Recognized on Derivatives in Condensed Consolidated Statement of Operations for the Thirteen Weeks Ended August 28, 2016 August 30, 2015 Commodity contracts Cost of goods sold $ 0.1 $ (9.3 ) Foreign exchange contracts Cost of goods sold 0.1 — Foreign exchange contracts Selling, general and administrative expense (1.2 ) 0.1 Total loss from derivative instruments not designated as hedging instruments $ (1.0 ) $ (9.2 ) As of August 28, 2016 , our open commodity contracts had a notional value (defined as notional quantity times market value per notional quantity unit) of $102.3 million and $75.5 million for purchase and sales contracts, respectively. As of May 29, 2016 , our open commodity contracts had a notional value of $107.5 million and $55.1 million for purchase and sales contracts, respectively. The notional amount of our foreign currency forward and cross currency swap contracts as of August 28, 2016 and May 29, 2016 was $114.9 million and $120.0 million , respectively. We enter into certain commodity, interest rate, and foreign exchange derivatives with a diversified group of counterparties. We continually monitor our positions and the credit ratings of the counterparties involved and 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. We have not incurred a material loss due to nonperformance in any period presented and do not expect to incur any such material loss. We also enter into futures and options transactions through various regulated exchanges. At August 28, 2016 , the maximum amount of loss due to the credit risk of the counterparties, had the counterparties failed to perform according to the terms of the contracts, was $20.1 million .

SHARE-BASED PAYMENTS	SHARE-BASED PAYMENTS For the first quarter of fiscal 2017 and 2016 , we recognized total stock-based compensation expense (including stock options, restricted stock units, cash-settled restricted stock units, and performance shares) of $14.8 million and $22.4 million , respectively. These amounts are inclusive of discontinued operations. Included in the total stock-based compensation expense for the first quarter of fiscal 2017 and 2016 was income of $0.1 million and expense of $0.2 million , respectively, related to stock options granted by a subsidiary in the subsidiary's shares to the subsidiary's employees. For the first quarter of fiscal 2017 , we granted 0.4 million restricted stock units at a weighted average grant date price of $47.85 , 0.4 million cash-settled restricted stock units at a weighted average grant date price of $48.07 , 1.1 million stock options at a weighted average exercise price of $48.11 , and 0.2 million performance shares at a weighted average grant date price of $46.94 . Performance shares are granted to selected executives and other key employees with vesting contingent upon meeting various Company-wide performance goals. The performance goals for the performance periods ending in fiscal 2017 are based upon an overarching earnings per share goal (for certain participants) and, for all participants, (a) our earnings before interest, taxes, depreciation, and amortization ("EBITDA") return on capital, and (b) revenue growth, each measured over the defined performance period. The awards actually earned will range from zero to two hundred percent of the targeted number of performance shares for the performance period ending in fiscal 2017. A payout equal to 25% of the participant's approved target incentive is required to be paid out if we achieve a threshold level of EBITDA return on capital for the performance period ending in fiscal 2017. The performance goal for one-third of the target number of performance shares for the performance period ending in fiscal 2018 (the "2018 performance period") is based upon an overarching earnings per share goal (for certain participants) and, for all participants, our fiscal 2016 EBITDA return on capital. Another one-third of the target number of performance shares granted for the 2018 performance period is based on an overarching earnings per share goal (for certain participants) and our fiscal 2017 EBITDA return on capital. The performance goal for the last one-third of the target number of performance shares granted for the 2018 performance period is expected to be set at the start of fiscal 2018. The performance goal for one-third of the target number of performance shares for the performance period ending in fiscal 2019 (the "2019 performance period") is based upon an overarching earnings per share goal (for certain participants) and our fiscal 2017 EBITDA return on capital. The performance goal for the final two-thirds of the target number of performance shares granted for the 2019 performance period is expected to be set at the start of fiscal 2018. Awards, if earned, will be paid in shares of our common stock. Subject to limited exceptions set forth in the performance share plan, any shares earned will be distributed at the end of the performance period. The value of the performance shares is adjusted based upon the market price of our common stock and current forecasted targets at the end of each reporting period and amortized as compensation expense over the vesting period. The weighted average Black-Scholes assumptions for stock options granted during the first quarter of fiscal 2017 were as follows: Expected volatility (%) 19.17 Dividend yield (%) 2.33 Risk-free interest rate (%) 1.02 Expected life of stock option (years) 4.94 The weighted average value of stock options granted during the first quarter of fiscal 2017 was $6.13 per option based upon a Black-Scholes methodology.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Income tax expense from continuing operations for the first quarter of fiscal 2017 and 2016 was $ 218.7 million and $ 85.0 million , respectively. The effective tax rate (calculated as the ratio of income tax expense to pre-tax income from continuing operations, inclusive of equity method investment earnings) from continuing operations was 54% and 34% for the first quarter of fiscal 2017 and 2016, respectively. The higher effective tax rate in the first quarter of fiscal 2017 reflects the following: • additional tax expense associated with non-deductible goodwill sold in connection with the dispositions of the Spicetec and JM Swank businesses, • additional tax expense associated with non-deductible goodwill for which an impairment charge was recognized, • an income tax benefit for excess tax benefits allowed upon the vesting/exercise of employee stock compensation awards by our employees, beyond that which is attributable to the original fair value of the awards upon the date of grant (see Note 1 for further discussion on adoption of ASU 2016-09), and • an income tax benefit associated with a tax planning strategy that allowed us to utilize certain state tax attributes. The amount of gross unrecognized tax benefits for uncertain tax positions, including positions impacting only the timing of tax benefits, was $39.2 million as of August 28, 2016 and $38.4 million as of May 29, 2016 . Included in the balance was $1.1 million as of both August 28, 2016 and May 29, 2016 , for tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. Because of the impact of deferred tax accounting, the disallowance of the shorter deductibility period would not affect the annual effective tax rate but would accelerate the payment of cash to the taxing authority to an earlier period. Any associated interest and penalties imposed would affect the tax rate. The gross unrecognized tax benefits excluded related liabilities for gross interest and penalties of $9.6 million and $9.3 million as of August 28, 2016 and May 29, 2016 , respectively. The net amount of unrecognized tax benefits at August 28, 2016 and May 29, 2016 that, if recognized, would impact the Company's effective tax rate was $28.3 million and $27.9 million , respectively. Recognition of these tax benefits would have a favorable impact on the Company's effective tax rate. We estimate that it is reasonably possible that the amount of gross unrecognized tax benefits will decrease by up to $9.1 million over the next twelve months due to various federal, state, and foreign audit settlements and the expiration of statutes of limitations. As of May 29, 2016, we had a deferred tax asset of $1.54 billion that was generated from the capital loss realized on the sale of the Private Brands operations. As of that date we held a valuation allowance of $1.40 billion , in order to reflect the uncertainty regarding the ultimate realization of the tax asset. During the first quarter of fiscal 2017, the balance of the deferred tax asset was adjusted for the capital gain realized on the sales of the Spicetec and JM Swank businesses, the realization of certain tax attributes based upon the contract terms of the Private Brands sale, and further refinement of the estimated tax asset. The deferred tax asset as of August 28, 2016 is $1.32 billion . We continue to hold a valuation allowance of this full amount, as we have not met the accounting requirements for recognition of a benefit at this time.

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIES In fiscal 1991, we acquired Beatrice Company ("Beatrice"). As a result of the acquisition of Beatrice and the significant pre-acquisition contingencies of the Beatrice businesses and its former subsidiaries, our condensed consolidated post-acquisition financial statements reflect liabilities associated with the estimated resolution of these contingencies. These include various litigation and environmental proceedings related to businesses divested by Beatrice prior to its acquisition by us. The litigation includes suits against a number of lead paint and pigment manufacturers, including ConAgra Grocery Products Company, LLC, a wholly owned subsidiary of the Company ("ConAgra Grocery Products"), and the Company as alleged successors to W. P. Fuller Co., a lead paint and pigment manufacturer owned and operated by Beatrice until 1967. Although decisions favorable to us have been rendered in Rhode Island, New Jersey, Wisconsin, and Ohio, we remain a defendant in active suits in Illinois and California. The Illinois suit seeks class-wide relief for reimbursement of costs associated with the testing of lead levels in blood. In California, a number of cities and counties joined in a consolidated action seeking abatement of the alleged public nuisance. On September 23, 2013, a trial of the California case concluded in the Superior Court of California for the County of Santa Clara, and on January 27, 2014, the court entered a judgment (the "Judgment") against ConAgra Grocery Products and two other defendants, which orders the creation of a California abatement fund in the amount of $1.15 billion . Liability is joint and several. The Company believes ConAgra Grocery Products did not inherit any liabilities of W. P. Fuller Co. The Company will continue to vigorously defend itself in this case and has appealed the Judgment to The Court of Appeal of the State of California Sixth Appellate District. The Company expects the appeal process will last several years. The absence of any linkage between ConAgra Grocery Products and W. P. Fuller Co. is a critical issue among others that the Company will continue to advance throughout the appeals process. It is not possible to estimate exposure in this case or the remaining case in Illinois (which is based on different legal theories). If ultimately necessary, the Company will look to its insurance policies for coverage; its carriers are on notice. However, the extent of insurance coverage is uncertain, and the Company cannot absolutely assure that the final resolution of these matters will not have a material adverse effect on its financial condition, results of operations, or liquidity. The environmental proceedings associated with Beatrice include litigation and administrative proceedings involving Beatrice's status as a potentially responsible party at 37 Superfund, proposed Superfund, or state-equivalent sites. These sites involve locations previously owned or operated by predecessors of Beatrice that used or produced petroleum, pesticides, fertilizers, dyes, inks, solvents, PCBs, acids, lead, sulfur, tannery wastes, and/or other contaminants. Beatrice has paid or is in the process of paying its liability share at 33 of these sites. Reserves for these matters have been established based on our best estimate of the undiscounted remediation liabilities, which estimates include evaluation of investigatory studies, extent of required clean-up, the known volumetric contribution of Beatrice and other potentially responsible parties, and its experience in remediating sites. The accrual for Beatrice-related environmental matters totaled $54.3 million as of August 28, 2016 , a majority of which relates to the Superfund and state-equivalent sites referenced above. We expect expenditures for Beatrice-related environmental matters to continue for up to 18 years . In certain limited situations, we will guarantee an obligation of an unconsolidated entity. At the time in which we initially provide such a guarantee, we assess the risk of financial exposure to us under these agreements. We consider the credit-worthiness of the guaranteed party, the value of any collateral pledged against the related obligation, and any other factors that may mitigate our risk. We actively monitor market and entity-specific conditions that may result in a change of our assessment of the risk of loss under these agreements. We are a party to various potato supply agreements. Under the terms of certain such potato supply agreements, we have guaranteed repayment of short-term bank loans of the potato suppliers, under certain conditions. At August 28, 2016 , the amount of supplier loans we have effectively guaranteed was $67.9 million . We have not established a liability for these guarantees, as we have determined that the likelihood of our required performance under the guarantees is remote. Federal income tax credits were generated related to our sweet potato production facility in Delhi, Louisiana. Third parties invested in these income tax credits. We have guaranteed these third parties the face value of the income tax credits over their statutory lives, through fiscal 2017, in the event that the income tax credits are recaptured or reduced. The face value of the income tax credits was $26.7 million as of August 28, 2016 . We believe the likelihood of recapture or reduction of the income tax credits is remote, and therefore we have not established a liability in connection with these guarantees. We are a party to a number of lawsuits and claims arising out of our ongoing business operations. Among these, there are lawsuits, claims, and matters related to the February 2007 recall of our peanut butter products. Among the matters outstanding during fiscal 2015 related to the peanut butter recall was an investigation by the U.S. Attorney's office in Georgia and the Consumer Protection Branch of the Department of Justice into the 2007 recall. Just prior to the end of fiscal 2015, we negotiated a resolution of this matter, which resulted in an executed plea agreement pursuant to which ConAgra Grocery Products will plead guilty to a single misdemeanor violation of the Food, Drug & Cosmetics Act. If the plea is accepted by the U.S. District Court for the Middle District of Georgia, the government’s investigation into the 2007 recall will conclude and ConAgra Grocery Products will make payments totaling $11.2 million to the federal government. Expenses related to this payment were accrued in previous periods. During fiscal 2013 and 2012, we recognized charges of $7.5 million and $17.5 million , respectively, in connection with this matter. During the fourth quarter of fiscal 2014, we reduced our accrual by $6.7 million . During the first quarter of fiscal 2015, we further reduced our accrual by $5.8 million and further reduced it by $1.2 million in the second quarter of fiscal 2015, based on ongoing discussions with the U.S. Attorney's office and the Department of Justice. The plea agreement is subject to Court approval, which will be sought along with the formal sentencing process in the coming months. In June 2009, an accidental explosion occurred at our manufacturing facility in Garner, North Carolina. This facility was the primary production facility for our Slim Jim ® branded meat snacks. In June 2009, the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives announced its determination that the explosion was the result of an accidental natural gas release, and not a deliberate act. During the fourth quarter of fiscal 2011, we settled our property and business interruption claims related to the Garner accident with our insurance providers. During the fourth quarter of fiscal 2011, Jacobs Engineering Group Inc. ("Jacobs"), our engineer and project manager at the site, filed a declaratory judgment action against us seeking indemnity for personal injury claims brought against it as a result of the accident. In the first quarter of fiscal 2012, our motion for summary judgment was granted and the suit was dismissed without prejudice on the basis that the suit was filed prematurely. In the third quarter of fiscal 2014, Jacobs refiled its action for indemnity. On March 25, 2016, a Douglas County jury in Nebraska rendered a verdict in favor of Jacobs and against us in the amount of $108.9 million plus post-judgment interest. Notice of Appeal was filed in September 2016. Although our insurance carriers have provided customary notices of reservation of their rights under the policies of insurance, we expect any ultimate exposure in this case to be limited to the applicable insurance deductible. We hold a fifty percent ownership interest in Lamb Weston/Meijer, V.O.F. (“Lamb Weston Meijer”), a Netherlands joint venture, headquartered in the Netherlands, that manufactures and sells frozen potato products principally in Europe. We and our partner are jointly and severally liable for all legal liabilities of Lamb Weston Meijer. As of August 28, 2016 and May 29, 2016, the total liabilities of Lamb Weston Meijer were $198.6 million and $203.7 million , respectively. Lamb Weston Meijer is well capitalized, with partners’ equity of $285.9 million and $284.5 million as of August 28, 2016 and May 29, 2016, respectively. We have not established a liability on our balance sheets for the obligations of Lamb Weston Meijer, as we have determined the likelihood of any required payment by us to settle such liabilities of Lamb Weston Meijer is remote. We lease certain office buildings from entities that we have determined to be variable interest entities. The lease agreements contain put options exercisable now and remain exercisable until generally 30 days after the end of the respective lease agreements, that allow the lessors to require us to purchase the buildings at the greater of original construction cost, or fair market value, without a lease in place. We have financial exposure with respect to these entities in the event we are required to purchase the leased buildings for a price in excess of the then current fair value under the applicable lease purchase options. We are amortizing the difference between the estimated put price and the estimated fair value (without a lease agreement in place) of each respective property over the remaining respective lease term within selling, general, and administrative expenses. As of August 28, 2016 , the estimated amount by which the put prices exceeded the fair values of the related properties was $58.5 million , of which we have accrued $11.1 million . As these buildings are worth considerably more when under lease agreements than when vacant, we may be able to mitigate some, or all, of the related financial exposure created by the put options by maintaining active lease agreements and/or by subleasing the buildings to credit worthy tenants. We do not expect to ultimately incur material financial losses as a result of the potential exercise of the lease put options by the lessors. After taking into account liabilities recognized for all of the foregoing matters, management believes the ultimate resolution of such matters should not have a material adverse effect on our financial condition, results of operations, or liquidity. It is reasonably possible that a change in one of the estimates of the foregoing matters may occur in the future and, as noted, while unlikely, the lead paint matter could result in a material final judgment. Costs of legal services associated with the foregoing matters are recognized in earnings as services are provided.

Defined Benefit Pension Plans and Defined Benefit Postretirement Plans Disclosure [Abstract]
PENSION AND POSTRETIREMENT BENEFITS	PENSION AND POSTRETIREMENT BENEFITS We have defined benefit retirement plans ("plans") for eligible salaried and hourly employees. Benefits are based on years of credited service and average compensation or stated amounts for each year of service. We also sponsor postretirement plans which provide certain medical and dental benefits ("other postretirement benefits") to qualifying U.S. employees. Components of pension benefit and other postretirement benefit costs are (includes amounts related to discontinued operations): Pension Benefits Thirteen weeks ended August 28, August 30, Service cost $ 16.7 $ 23.8 Interest cost 30.0 41.0 Expected return on plan assets (53.8 ) (66.9 ) Amortization of prior service cost 0.6 0.7 Benefit cost — Company plans (6.5 ) (1.4 ) Pension benefit cost — multi-employer plans 2.3 2.3 Total benefit cost (benefit) $ (4.2 ) $ 0.9 Postretirement Benefits Thirteen weeks ended August 28, August 30, Service cost $ — $ 0.1 Interest cost 1.1 2.0 Amortization of prior service benefit (1.7 ) (2.0 ) Recognized net actuarial loss 0.1 — Total cost (benefit) $ (0.5 ) $ 0.1 Beginning in fiscal 2017, the Company has elected to use a split discount rate (spot-rate approach) for the U.S. plans and certain foreign plans. Historically, a single weighted-average discount rate was used in the calculation of service and interest costs, both of which are components of pension benefit costs. The spot-rate approach applies separate discount rates for each projected benefit payment in the calculation of pension service and interest cost. This change is considered a change in accounting estimate and has been applied prospectively. The pre-tax reduction in total pension benefit cost associated with this change in the first quarter of fiscal 2017 was approximately $7.4 million . The weighted-average discount rates for service and interest costs under the spot-rate approach used for pension benefit cost in fiscal 2017 were 4.14% and 3.15% , respectively. During the first quarter of fiscal 2017 , we contributed $3.0 million to our pension plans and contributed $4.5 million to our other postretirement plans. Based upon the current funded status of the plans and the current interest rate environment, we anticipate making further contributions of approximately $9.5 million to our pension plans for the remainder of fiscal 2017 . We anticipate making further contributions of $17.6 million to our other postretirement plans during the remainder of fiscal 2017 . These estimates are based on ERISA guidelines, current tax laws, plan asset performance, and liability assumptions, which are subject to change.

FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS FASB guidance establishes a three-level fair value hierarchy based upon the assumptions (inputs) used to price assets or liabilities. The three levels of inputs used to measure fair value are as follows: Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities, Level 2 — Observable inputs other than those included in Level 1, such as quoted prices for similar assets and liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets, and Level 3 — Unobservable inputs reflecting our own assumptions and best estimate of what inputs market participants would use in pricing the asset or liability. The fair values of our Level 2 derivative instruments were determined using valuation models that use market observable inputs including interest rate curves and both forward and spot prices for currencies and commodities. Derivative assets and liabilities included in Level 2 primarily represent commodity and foreign currency option and forward contacts, and cross-currency swaps. The following table presents our financial assets and liabilities measured at fair value on a recurring basis, based upon the level within the fair value hierarchy in which the fair value measurements fall, as of August 28, 2016 : Level 1 Level 2 Level 3 Net Value Assets: Derivative assets $ 3.0 $ 20.1 $ — $ 23.1 Available-for-sale securities 3.2 — — 3.2 Deferred compensation assets 0.7 — — 0.7 Total assets $ 6.9 $ 20.1 $ — $ 27.0 Liabilities: Derivative liabilities $ — $ 0.4 $ — $ 0.4 Deferred compensation liabilities 54.2 — — 54.2 Total liabilities $ 54.2 $ 0.4 $ — $ 54.6 The following table presents our financial assets and liabilities measured at fair value on a recurring basis, based upon the level within the fair value hierarchy in which the fair value measurements fall, as of May 29, 2016 : Level 1 Level 2 Level 3 Net Value Assets: Derivative assets $ 4.7 $ 21.4 $ — $ 26.1 Available-for-sale securities 3.0 — — 3.0 Deferred compensation assets 0.7 — — 0.7 Total assets $ 8.4 $ 21.4 $ — $ 29.8 Liabilities: Derivative liabilities $ — $ 0.7 $ — $ 0.7 Deferred compensation liabilities 46.5 — — 46.5 Total liabilities $ 46.5 $ 0.7 $ — $ 47.2 Certain assets and liabilities, including long-lived assets, goodwill, asset retirement obligations, and cost and equity investments are measured at fair value on a nonrecurring basis. In the first quarter of fiscal 2017, we recognized a goodwill impairment charge of $139.2 million and an impairment of a non-amortizing intangible asset of $24.4 million in the International segment. The fair value of the non-amortizing intangible asset, a brand, was estimated using the "Relief From Royalty" method. The carrying amount of long-term debt (including current installments) was $4.9 billion as of August 28, 2016 and $5.5 billion as of May 29, 2016 . Based on current market rates, the fair value of this debt (level 2 liabilities) at August 28, 2016 and May 29, 2016 , was estimated at $5.4 billion and $5.9 billion , respectively.

Segment Reporting [Abstract]
BUSINESS SEGMENTS AND RELATED INFORMATION	BUSINESS SEGMENTS AND RELATED INFORMATION In the first quarter of fiscal 2017, in anticipation of the Lamb Weston spinoff transaction and other organizational changes, we reorganized our reporting segments. We now reflect our results of operations in five reporting segments: Grocery & Snacks, Refrigerated & Frozen, International, Foodservice, and Commercial. Prior periods have been reclassified to conform to the revised segment presentation. The Grocery & Snacks reporting segment principally includes branded, shelf-stable food products sold in various retail channels in the United States. The Refrigerated & Frozen reporting segment includes branded, temperature controlled food products sold in various retail channels in the United States. The International reporting segment principally includes branded, food products, in various temperature states, sold in various retail and foodservice channels outside of the United States. The Foodservice reporting segment includes branded and customized food products, including meals, entrees, prepared potatoes, sauces and a variety of custom-manufactured culinary products packaged for sale to restaurants and other foodservice establishments in the United States. The Commercial reporting segment includes commercially branded and private label food and ingredients, which are sold primarily to commercial, restaurant, foodservice, food manufacturing, and industrial customers. The segment's primary food items included: frozen potato and sweet potato items and a variety of vegetable, and spices, which were sold under brands such as Lamb Weston® and Spicetec Flavors & Seasonings®. The Spicetec and JM Swank businesses were sold in the first quarter of fiscal 2017. We do not aggregate operating segments when determining our reporting segments. Intersegment sales have been recorded at amounts approximating market. Operating profit for each of the segments is based on net sales less all identifiable operating expenses. General corporate expense, net interest expense, and income taxes have been excluded from segment operations. Thirteen weeks ended August 28, August 30, Net sales Grocery & Snacks $ 757.2 $ 800.5 Refrigerated & Frozen 604.6 657.6 International 194.7 206.4 Foodservice 268.0 270.6 Commercial 843.0 859.8 Total net sales $ 2,667.5 $ 2,794.9 Operating profit Grocery & Snacks $ 180.5 $ 139.5 Refrigerated & Frozen 92.2 81.1 International (149.2 ) 16.5 Foodservice 21.7 26.1 Commercial 346.4 111.8 Total operating profit $ 491.6 $ 375.0 Equity method investment earnings 23.6 37.0 General corporate expense 49.0 79.3 Interest expense, net 59.0 80.3 Income tax expense 218.7 85.0 Income from continuing operations $ 188.5 $ 167.4 Less: Net income attributable to noncontrolling interests 3.8 1.7 Income from continuing operations attributable to ConAgra Foods, Inc. $ 184.7 $ 165.7 Presentation of Derivative Gains (Losses) for Economic Hedges of Forecasted Cash Flows in Segment Results Derivatives used to manage commodity price risk and foreign currency risk are not designated for hedge accounting treatment. We believe these derivatives provide economic hedges of certain forecasted transactions. As such, these derivatives are recognized at fair market value with realized and unrealized gains and losses recognized in general corporate expenses. The gains and losses are subsequently recognized in the operating results of the reporting segments in the period in which the underlying transaction being economically hedged is included in earnings. In the event that management determines a particular derivative entered into as an economic hedge of a forecasted commodity purchase has ceased to function as an economic hedge, we cease recognizing further gains and losses on such derivatives in corporate expense and begin recognizing such gains and losses within segment operating results, immediately. The following table presents the net derivative gains (losses) from economic hedges of forecasted commodity consumption and the foreign currency risk of certain forecasted transactions, under this methodology: Thirteen weeks ended August 28, August 30, Net derivative gains (losses) incurred $ 0.2 $ (9.3 ) Less: Net derivative losses allocated to reporting segments (0.8 ) (7.1 ) Net derivative gains (losses) recognized in general corporate expenses $ 1.0 $ (2.2 ) Net derivative losses allocated to Grocery & Snacks $ (0.5 ) $ (4.2 ) Net derivative losses allocated to Refrigerated & Frozen (0.2 ) (1.6 ) Net derivative gains allocated to International Foods 0.1 — Net derivative losses allocated to Foodservice (0.3 ) (0.6 ) Net derivative gains (losses) allocated to Commercial 0.1 (0.7 ) Net derivative losses included in segment operating profit $ (0.8 ) $ (7.1 ) As of August 28, 2016 , the cumulative amount of net derivative gains from economic hedges that had been recognized in general corporate expenses and not yet allocated to reporting segments was $4.2 million . This amount reflected net gains of $1.4 million incurred during the thirteen weeks ended August 28, 2016 , as well as net gains of $2.8 million incurred prior to fiscal 2017 . Based on our forecasts of the timing of recognition of the underlying hedged items, we expect to reclassify to segment operating results gains of $4.5 million in fiscal 2017 and losses of $0.3 million in fiscal 2018 and thereafter. Assets by Segment The majority of our manufacturing assets are shared across multiple reporting segments. Output from these facilities used by each reporting segment can change from fiscal year to fiscal year. Also, working capital balances are not tracked by reporting segment. Therefore, it is impracticable to allocate those assets to the reporting segments, as well as disclose total assets by segment. Other Information Our largest customer, Wal-Mart Stores, Inc. and its affiliates, accounted for 18% of consolidated net sales in both the first quarter of fiscal 2017 and 2016 , primarily in the Grocery & Snacks and Refrigerated & Frozen segments. Wal-Mart Stores, Inc. and its affiliates accounted for approximately 20% of consolidated net receivables as of both August 28, 2016 and May 29, 2016 , primarily in the Grocery & Snacks and Refrigerated & Frozen segments. Spinoff of the Lamb Weston Business On November 18, 2015, we announced our plans to separate ConAgra Foods, Inc. into two public companies, Conagra Brands and Lamb Weston. The transaction, expected to be structured as a spinoff of the Lamb Weston business to the shareholders of ConAgra Foods in the fall of calendar 2016, is expected to be tax free to the Company and its shareholders. In addition, we expect the Lamb Weston operations will be presented as discontinued operations upon the completion of the spinoff.

SUMMARY OF SIGNIFICANT ACCOUN24

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Aug. 28, 2016
Accounting Policies [Abstract]
Basis of Consolidation	Basis of Consolidation — The condensed consolidated financial statements include the accounts of ConAgra Foods, Inc. and all majority-owned subsidiaries. In addition, the accounts of all variable interest entities for which we have been determined to be the primary beneficiary are included in our condensed consolidated financial statements from the date such determination is made. All significant intercompany investments, accounts, and transactions have been eliminated.
Comprehensive Income	Comprehensive Income — Comprehensive income includes net income, currency translation adjustments, certain derivative-related activity, changes in the value of available-for-sale investments, and changes in prior service cost and net actuarial gains (losses) from pension (for amounts not in excess of the 10% corridor) and post-retirement health care plans. We generally deem our foreign investments to be essentially permanent in nature and we do not provide for taxes on currency translation adjustments arising from converting the investment denominated in a foreign currency to U.S. dollars. When we determine that a foreign investment, as well as undistributed earnings, are no longer permanent in nature, estimated taxes are provided for the related deferred tax liability (asset), if any, resulting from currency translation adjustments.
Reclassifications and other changes	Reclassifications and other changes — Certain prior year amounts have been reclassified to conform with current year presentation.
Use of Estimates	Use of Estimates — Preparation of financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") requires management to make estimates and assumptions. These estimates and assumptions affect reported amounts of assets, liabilities, revenues, and expenses as reflected in the condensed consolidated financial statements. Actual results could differ from these estimates.
Accounting Changes and Recently Issued Accounting Standards	Accounting Changes — In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-09, Improvements to Employee Share-Based Payment Accounting, which simplifies the accounting for income taxes, among other changes, related to stock-based compensation. We elected to early adopt this ASU as of the beginning of fiscal 2017. For the first quarter of fiscal 2017, we recognized all excess tax benefits and tax deficiencies as income tax expense or benefit as a discrete event. An income tax benefit of approximately $11.6 million was recognized in the first quarter of fiscal 2017 as a result of the adoption of ASU 2016-09. The treatment of forfeitures has changed as we have elected to discontinue our past process of estimating the number of forfeitures and now account for forfeitures as they occur. As such, this had a cumulative effect on retained earnings of $3.9 million , net of tax. We have elected to present the cash flow statement on a retrospective transition method and prior periods have been adjusted to present the excess tax benefits as part of cash flows from operating activities. This resulted in an increase in cash flows from operating activities and a decrease in cash flows from financing activities of $26.3 million in the first quarter of fiscal 2016. Recently Issued Accounting Standards — In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP. On July 9, 2015, the FASB deferred the effective date of the new revenue recognition standard by one year. Based on the FASB’s ASU, we will apply the new revenue standard in our fiscal year 2019. Early adoption in our fiscal year 2018 is permitted. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. The standard permits the use of either the retrospective or cumulative effect transition method. In July 2015, the FASB issued ASU 2015-11, Inventory , which requires an entity to measure inventory within the scope at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The effective date for the standard is for fiscal years beginning after December 15, 2016. Early adoption is permitted. The standard is to be applied prospectively. We do not expect ASU 2015-11 to have a material impact to our financial statements. In February 2016, the FASB issued its final lease accounting standard, FASB Accounting Standard Codification ("ASC") Topic 842, Leases , which requires lessees to reflect most leases on their balance sheet as assets and obligations. The effective date for the standard is for fiscal years beginning after December 15, 2018. Early adoption is permitted. We are evaluating the effect that ASC 842 will have on our consolidated financial statements and related disclosures. The standard is to be applied under the modified retrospective method, with elective reliefs, which requires application of the new guidance for all periods presented.
