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 Brands, Inc. (formerly ConAgra Foods, Inc., the "Company", "we", "us", or "our") Annual Report on Form 10-K for the fiscal year ended May 28, 2017 . 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 Brands, 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. On November 9, 2016, the Company completed the spinoff of Lamb Weston Holdings, Inc. ("Lamb Weston") through a distribution of 100% of the Company's interest in Lamb Weston to holders of shares of the Company's common stock as of November 1, 2016 (the "Spinoff"). In accordance with U.S. generally accepted accounting principles ("U.S. GAAP"), the results of operations of the Lamb Weston operations are presented as discontinued operations and, as such, have been excluded from continuing operations and segment results for all periods presented (see Note 3 for additional discussion). 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. On foreign investments we deem to be essentially permanent in nature, we do not provide for taxes on currency translation adjustments arising from converting an investment denominated in 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 will be provided for the related deferred tax liability (asset), if any, resulting from currency translation adjustments. The following table details the accumulated balances for each component of other comprehensive income (loss), net of tax: November 26, 2017 May 28, 2017 Currency translation losses, net of reclassification adjustments $ (78.7 ) $ (98.6 ) Derivative adjustments, net of reclassification adjustments (0.4 ) (1.1 ) Unrealized gains (losses) on available-for-sale securities 0.1 (0.3 ) Pension and post-employment benefit obligations, net of reclassification adjustments (86.2 ) (112.9 ) Accumulated other comprehensive loss $ (165.2 ) $ (212.9 ) 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 Earnings 1 November 26, 2017 November 27, 2016 Net derivative adjustment, net of tax: Cash flow hedges $ 0.1 $ — Interest expense, net 0.1 — Total before tax — — Income tax expense $ 0.1 $ — Net of tax Pension and postretirement liabilities: Net prior service benefit $ (0.2 ) $ (0.9 ) Selling, general and administrative expenses (0.2 ) (0.9 ) Total before tax 0.1 0.4 Income tax expense $ (0.1 ) $ (0.5 ) Net of tax Twenty-six weeks ended Affected Line Item in the Condensed Consolidated Statement of Earnings 1 November 26, 2017 November 27, 2016 Net derivative adjustment, net of tax: Cash flow hedges $ 0.1 $ — Interest expense, net 0.1 — Total before tax — — Income tax expense $ 0.1 $ — Net of tax Pension and postretirement liabilities: Net prior service benefit $ (0.3 ) $ (1.8 ) Selling, general and administrative expenses (0.3 ) (1.8 ) Total before tax 0.1 0.7 Income tax expense $ (0.2 ) $ (1.1 ) Net of tax 1 Amounts in parentheses indicate income recognized in the Condensed Consolidated Statements of Earnings. Cash and cash equivalents — Cash and all highly liquid investments with an original maturity of three months or less at the date of acquisition, including short-term time deposits and government agency and corporate obligations, are classified as cash and cash equivalents. 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. 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 July 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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. We adopted this ASU prospectively in fiscal 2018. The adoption of this guidance did not have a material impact to our financial statements. 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 in the process of documenting the impact of the guidance on our current accounting policies and practices in order to identify material differences, if any, that would result from applying the new requirements to our revenue contracts. We continue to make progress on our revenue recognition review and are also in the process of evaluating the impact, if any, on changes to our business processes, systems, and controls to support recognition and disclosure requirements under the new guidance. We continue to evaluate 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 January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities , which addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The effective date for this standard is for fiscal years beginning after December 31, 2017. Early adoption is not permitted except for certain provisions. We do not expect ASU 2016-01 to have a material impact to our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases , Topic 842, 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 this standard 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. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments , which clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows. The effective date for the standard is for fiscal years beginning after December 15, 2017. Early adoption is permitted. We do not expect ASU 2016-15 to have a material impact to our consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash , which provides amendments to current guidance to address the classifications and presentation of changes in restricted cash in the statement of cash flows. The effective date for the standard is for fiscal years beginning after December 15, 2017. Early adoption is permitted. We do not expect ASU 2016-18 to have a material impact to our consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business , which provides a new framework for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The effective date for the standard is for fiscal years beginning after December 15, 2017. Early adoption is permitted. We do not expect ASU 2017-01 to have a material impact to our consolidated financial statements. In March 2017, the FASB issued ASU 2017-07, Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost , which requires companies to present the service cost component of net benefit cost in the same line items in which they report compensation cost. Companies will present all other components of net benefit cost outside operating income, if this subtotal is presented. The effective date for the standard is for fiscal years beginning after December 15, 2017. Early adoption is permitted. We do not expect ASU 2017-07 to have a material impact to our consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities , which improves the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements and make certain targeted improvements to simplify the application of the hedge accounting guidance in current U.S. GAAP. The amendments in this update better align an entity's risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and presentation of hedge results. The effective date for the standard is for fiscal years beginning after December 15, 2018. Early adoption is permitted. We are currently evaluating the impact of our pending adoption of this standard on our consolidated financial statements.

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS In October 2017, we acquired Angie's Artisan Treats, LLC, maker of Angie's ® BOOMCHICKAPOP ® ready-to-eat popcorn, for a cash purchase price of $249.6 million , net of cash acquired and subject to working capital adjustments. Approximately $156.5 million has been classified as goodwill, of which $95.4 million is deductible for income tax purposes. Approximately $73.8 million and $10.3 million of the purchase price has been allocated to non-amortizing and amortizing intangible assets, respectively. The business is included in the Grocery & Snacks segment. In April 2017, we acquired protein-based snacking businesses Thanasi Foods LLC, maker of Duke's ® meat snacks, and BIGS LLC, maker of BIGS ® seeds, for $217.6 million in cash, net of cash acquired, including working capital adjustments. Approximately $133.3 million has been classified as goodwill, of which $70.9 million is deductible for income tax purposes. Approximately $65.1 million and $16.1 million of the purchase price has been allocated to non-amortizing and amortizing intangible assets, respectively. These businesses are included in the Grocery & Snacks segment. In September 2016, we acquired the operating assets of Frontera Foods, Inc. and Red Fork LLC, including the Frontera ® , Red Fork ® , and Salpica ® brands. These businesses make authentic, gourmet Mexican food products and contemporary American cooking sauces. We acquired the businesses for a cash purchase price of $108.2 million , net of cash acquired, including working capital adjustments. Approximately $39.5 million has been classified as goodwill and $47.1 million and $19.6 million has been classified as non-amortizing and amortizing intangible assets, respectively. The amount allocated to goodwill is deductible for tax purposes. These businesses are reflected principally within the Grocery & Snacks segment, and to a lesser extent within the Refrigerated & Frozen and International segments. These acquisitions collectively contributed $37.4 million and $68.4 million to net sales during the second quarter and first half of fiscal 2018, respectively, and $6.4 million for each of the second quarter and first half of fiscal 2017. For each of these acquisitions, the amounts allocated to goodwill were primarily attributable to anticipated synergies, product portfolios, and other intangibles that do not qualify for separate recognition. Under the acquisition method of accounting, the assets acquired and liabilities assumed in these acquisitions were recorded at their respective estimated fair values at the date of acquisition. Subsequent to the end of the second quarter of fiscal 2018, we entered into a definitive agreement to acquire the Sandwich Bros. of Wisconsin ® business, maker of frozen breakfast and entree flatbread pocket sandwiches, for a cash purchase price of $87 million , net of cash acquired and subject to working capital adjustments. The business will be primarily included in the Refrigerated & Frozen segment. The transaction is expected to close in early calendar year 2018, subject to customary closing conditions, including the receipt of any applicable regulatory approvals.

DISCONTINUED OPERATIONS AND OTHER DIVESTITURES	DISCONTINUED OPERATIONS AND OTHER DIVESTITURES Lamb Weston Spinoff On November 9, 2016, we completed the Spinoff of our Lamb Weston business. As of such date, we did not beneficially own any equity interest in Lamb Weston and no longer consolidated Lamb Weston into our financial results. The business results were previously reported in the Commercial segment. We reflected the results of this business as discontinued operations for all periods presented. The summary comparative financial results of the Lamb Weston business through the date of the Spinoff, included within discontinued operations, were as follows: Thirteen weeks ended Twenty-six weeks ended November 26, 2017 November 27, 2016 November 26, 2017 November 27, 2016 Net sales $ — $ 636.0 $ — $ 1,407.9 Income (loss) from discontinued operations before income taxes and equity method investment earnings $ — $ 46.3 $ (0.3 ) $ 175.1 Income (loss) before income taxes and equity method investment earnings — 46.3 (0.3 ) 175.1 Income tax expense (benefit) — 39.1 (0.1 ) 88.6 Equity method investment earnings — 5.3 — 15.9 Income (loss) from discontinued operations, net of tax — 12.5 (0.2 ) 102.4 Less: Net income attributable to noncontrolling interests — 3.2 — 6.8 Net income (loss) from discontinued operations attributable to Conagra Brands, Inc. $ — $ 9.3 $ (0.2 ) $ 95.6 For the second quarter and first half of fiscal 2017 , we incurred $62.2 million and $72.0 million , respectively, of expenses in connection with the Spinoff primarily related to professional fees and contract services associated with preparation of regulatory filings and separation activities. These expenses are reflected in income from discontinued operations. In connection with the Spinoff, total assets of $2.28 billion and total liabilities of $2.98 billion (including debt of $2.46 billion ) were transferred to Lamb Weston. As part of the consideration for the Spinoff, the Company received a cash payment from Lamb Weston in the amount of $823.5 million . See Note 5 for discussion of the debt-for-debt exchange related to the Spinoff. We entered into a transition services agreement in connection with the Lamb Weston Spinoff and recognized $0.8 million and $2.1 million of income for the performance of services during the second quarter and first half of fiscal 2018 , respectively, classified within selling, general and administrative ("SG&A") expenses.

Results of operations for the Private Brands business were immaterial for all periods presented. We entered into a transition services agreement with TreeHouse Foods, Inc. and recognized $ 0.5 million and $ 5.4 million of income for the performance of services during the second quarter of fiscal 2018 and 2017 , respectively, classified within selling, general and administrative expenses. We recognized $2.2 million and $11.5 million of transition services agreement income in the first half of fiscal 2018 and 2017 , respectively. Other Divestitures During the fourth quarter of fiscal 2017, we signed an agreement to sell our Wesson ® oil business, which is part of our Grocery & Snacks segment, to The J.M. Smucker Company ("Smucker").

Restructuring and Related Activities [Abstract]
RESTRUCTURING ACTIVITIES	RESTRUCTURING ACTIVITIES Supply Chain and Administrative Efficiency Plan In May 2013, we announced the Supply Chain and Administrative Efficiency Plan (the "SCAE Plan"), our plan to integrate and restructure the operations of our Private Brands business, improve SG&A effectiveness and efficiencies, and optimize our supply chain network, manufacturing assets, dry distribution centers, and mixing centers. In the second quarter of fiscal 2016, we announced plans to realize efficiency benefits by reducing SG&A expenses and enhancing trade spend processes and tools, which plans were included as part of the SCAE Plan. Although we divested the Private Brands business, we have continued to implement the SCAE Plan, including by working to optimize our supply chain network, pursue cost reductions through our SG&A functions, enhance trade spend processes and tools, and improve productivity. 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 second quarter of fiscal 2018 , 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 November 26, 2017 , our Board of Directors has approved the incurrence of up to $900.9 million of expenses in connection with the SCAE Plan, including expenses allocated for the Private Brands and Lamb Weston operations. We have incurred or expect to incur approximately $464.8 million of charges ( $320.7 million of cash charges and $144.1 million of non-cash charges) for actions identified to date under the SCAE Plan related to our continuing operations. In the second quarter and first half of fiscal 2018 , we recognized charges of $7.1 million and $18.5 million , respectively, in association with the SCAE Plan related to our continuing operations. In the second quarter and first half of fiscal 2017, we recognized $19.8 million and $ 33.9 million , respectively, in association with 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 half of fiscal 2018 ): Grocery & Snacks Refrigerated & Frozen International Foodservice Corporate Total Pension costs $ 32.9 $ 1.5 $ — $ — $ — $ 34.4 Accelerated depreciation 32.2 18.6 — — 1.2 52.0 Other cost of goods sold 10.0 2.1 — — — 12.1 Total cost of goods sold 75.1 22.2 — — 1.2 98.5 Severance and related costs, net 26.0 10.3 3.4 7.9 103.4 151.0 Fixed asset impairment (net of gains on disposal) 5.9 6.9 — — 11.2 24.0 Accelerated depreciation — — — — 4.7 4.7 Contract/lease cancellation expenses 0.9 0.6 0.6 — 86.2 88.3 Consulting/professional fees 1.1 0.4 0.1 — 54.1 55.7 Other selling, general and administrative expenses 16.1 3.2 — — 23.3 42.6 Total selling, general and administrative expenses 50.0 21.4 4.1 7.9 282.9 366.3 Consolidated total $ 125.1 $ 43.6 $ 4.1 $ 7.9 $ 284.1 $ 464.8 During the second quarter of fiscal 2018 , we recognized the following pre-tax expenses for the SCAE Plan related to our continuing operations: Grocery & Snacks International Corporate Total Pension costs $ 2.1 $ — $ — $ 2.1 Other cost of goods sold 1.3 — — 1.3 Total cost of goods sold 3.4 — — 3.4 Severance and related costs, net (0.2 ) 0.9 0.6 1.3 Fixed asset impairment (net of gains on disposal) (1.5 ) — — (1.5 ) Accelerated depreciation — — 0.7 0.7 Contract/lease cancellation expenses 0.1 — (0.1 ) — Consulting/professional fees 0.1 — 0.4 0.5 Other selling, general and administrative expenses 2.1 — 0.6 2.7 Total selling, general and administrative expenses 0.6 0.9 2.2 3.7 Consolidated total $ 4.0 $ 0.9 $ 2.2 $ 7.1 Included in the above table are $7.7 million of charges that have resulted or will result in cash outflows and net non-cash gains of $0.6 million .

Debt Disclosure [Abstract]
LONG-TERM DEBT AND REVOLVING CREDIT FACILITY	LONG-TERM DEBT AND REVOLVING CREDIT FACILITY At November 26, 2017 , we had a revolving credit facility (the "Facility") with a syndicate of financial institutions that provides for a maximum aggregate principal amount outstanding at any one time of $1.25 billion (subject to increase to a maximum aggregate principal amount of $1.75 billion with the consent of the lenders). As of November 26, 2017 , we were in compliance with all financial covenants under the Facility. During the second quarter of fiscal 2018, we issued $ 500.0 million aggregate principal amount of floating rate notes due October 9, 2020. The notes bear interest at a rate equal to three-month LIBOR plus 0.50% per annum. During the third quarter of fiscal 2017, we repaid the remaining principal balance of $224.8 million of our 5.819% senior notes due 2017 and $248.2 million principal amount of our 7.0% senior notes due 2019, in each case prior to maturity, resulting in a net loss on early retirement of debt of $32.7 million . In connection with the Spinoff (see Note 3), Lamb Weston issued to us $1.54 billion aggregate principal amount of senior notes (the "Lamb Weston notes"). On November 9, 2016, we exchanged the Lamb Weston notes for $250.2 million aggregate principal amount of our 5.819% senior notes due 2017, $880.4 million aggregate principal amount of our 1.9% senior notes due 2018, $154.9 million aggregate principal amount of our 2.1% senior notes due 2018, $86.9 million aggregate principal amount of our 7.0% senior notes due 2019, and $71.1 million aggregate principal amount of our 4.95% senior notes due 2020 (collectively, the "Conagra notes"), which had been purchased in the open market by certain investment banks prior to the Spinoff. Following the exchange, we canceled the Conagra notes. These actions resulted in a net loss of $60.6 million as a cost of early retirement of debt. Net interest expense from continuing operations consists of: Thirteen weeks ended Twenty-six weeks ended November 26, November 27, November 26, November 27, Long-term debt $ 39.4 $ 56.6 $ 77.5 $ 117.5 Short-term debt 0.7 0.2 1.1 0.4 Interest income (1.1 ) (0.8 ) (2.0 ) (1.5 ) Interest capitalized (1.0 ) (1.9 ) (2.2 ) (4.1 ) $ 38.0 $ 54.1 $ 74.4 $ 112.3

VARIABLE INTEREST ENTITIES

Organization, Consolidation and Presentation of Financial Statements [Abstract]
VARIABLE INTEREST ENTITIES	VARIABLE INTEREST ENTITIES Variable Interest Entities Not Consolidated We have variable interests in certain 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 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 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 November 26, 2017 and May 28, 2017 , the estimated amount by which the put prices exceeded the fair values of the related properties was $50.7 million , of which we had accrued $10.2 million and $8.4 million , respectively. In December 2017, subsequent to the second quarter of fiscal 2018, we purchased a building that had been subject to a put option. We will recognize a net loss of approximately $13 million for the early termination of the associated lease in our third quarter of fiscal 2018. Also in December 2017, we made an offer to purchase another property subject to a put option. We have not entered into a binding legal contract in connection with this offer. However, if our offer is accepted, we may recognize an estimated loss of $30 million to $40 million , upon closing of the transaction, for the early exit of an unfavorable lease contract. If this transaction is completed, we would have one remaining leased building subject to a put option for which the put option price exceeds the estimated fair value by $8.2 million , of which we had accrued $1.0 million , as of November 26, 2017 . These leases, with the exception of one , are accounted for as operating leases. A capital lease asset and related lease obligation of $25.3 million and $28.9 million , respectively, were included in the Condensed Consolidated Balance Sheets as of November 26, 2017 . 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.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER IDENTIFIABLE INTANGIBLE ASSETS	GOODWILL AND OTHER IDENTIFIABLE INTANGIBLE ASSETS The change in the carrying amount of goodwill for the first half of fiscal 2018 was as follows: Grocery & Snacks Refrigerated & Frozen International Foodservice Total Balance as of May 28, 2017 $ 2,439.1 $ 1,037.3 $ 253.6 $ 571.1 $ 4,301.1 Acquisitions 156.5 — — — 156.5 Purchase accounting adjustments (1.5 ) — — — (1.5 ) Currency translation — 0.9 — — 0.9 Balance as of November 26, 2017 $ 2,594.1 $ 1,038.2 $ 253.6 $ 571.1 $ 4,457.0 Other identifiable intangible assets were as follows: November 26, 2017 May 28, 2017 Gross Carrying Amount Accumulated Amortization Gross Carrying Amount Accumulated Amortization Non-amortizing intangible assets $ 908.8 $ — $ 834.1 $ — Amortizing intangible assets 587.3 197.9 575.4 180.2 $ 1,496.1 $ 197.9 $ 1,409.5 $ 180.2 In the first quarter of fiscal 2017, in anticipation of the Spinoff, we changed our reporting segments. In accordance with applicable accounting guidance, we were required to determine new reporting units at a lower level (at the operating segment or one level lower, as applicable). When such a determination was made, we were required to perform a goodwill impairment analysis for each of the new reporting units. We performed an assessment of impairment of goodwill for the new Canadian reporting unit within the new International reporting segment. Estimating the fair value of individual reporting units requires us to make assumptions and estimates regarding our future plans and future industry and economic conditions. We estimated the future cash flows of the Canadian reporting unit and calculated the net present value of those estimated cash flows using a risk adjusted discount rate, in order to estimate the fair value of each reporting unit from the perspective of a market participant. We used discount rates and terminal growth rates of 7.5% and 2% , respectively, to calculate the present value of estimated future cash flows. We then compared the estimated fair value of the reporting unit to the historical carrying value (including allocated assets and liabilities of certain shared and Corporate functions), and determined that the fair value of the reporting unit was less than the carrying value in the first quarter of fiscal 2017. With the assistance of a third-party valuation specialist, we estimated the fair value of the assets and liabilities of this reporting unit in order to determine the implied fair value of goodwill. We recognized an impairment charge for the difference between the implied fair value of goodwill and the carrying value of goodwill. Accordingly, during the first quarter of fiscal 2017, we recorded charges totaling $139.2 million for the impairment of goodwill. As part of the assessment of the fair value of each asset and liability within the Canadian reporting unit, with the assistance of the third-party valuation specialist, we estimated the fair value of our Canadian Del Monte ® brand to be less than its carrying value. In accordance with applicable accounting guidance, we recognized an impairment charge of $24.4 million to write-down the intangible asset to its estimated fair value. We also performed an assessment of impairment of goodwill for the new Mexican reporting unit within the International reporting segment using similar methods to those described above. We used discount rates and terminal growth rates of 8.5% and 3% , respectively, to calculate the present value of estimated future cash flows. We determined that the estimated fair value of this reporting unit exceeded the carrying value of its net assets by approximately 5% . Accordingly, we did not recognize an impairment of the goodwill in the Mexican reporting unit. During the second quarter of fiscal 2017, as a result of further deterioration in forecasted sales and profits primarily due to foreign exchange rates, we performed an additional assessment of impairment of goodwill for the new Mexican reporting unit. We used discount rates and terminal growth rates of 8.5% and 3% , respectively, to calculate the present value of estimated future cash flows. We then compared the estimated fair value of the reporting unit to the historical carrying value (including allocated assets and liabilities of certain shared and Corporate functions), and determined that the fair value of the reporting unit was less than the carrying value in the second quarter of fiscal 2017. With the assistance of a third-party valuation specialist, we estimated the fair value of the assets and liabilities of this reporting unit in order to determine the implied fair value of goodwill. We recognized an impairment charge for the difference between the implied fair value of goodwill and the carrying value of goodwill. Accordingly, during the second quarter of fiscal 2017, we recorded charges totaling $43.9 million for the impairment of goodwill. Non-amortizing intangible assets are comprised of brands and trademarks. Amortizing intangible assets, carrying a remaining weighted average life of approximately 14 years , are principally composed of customer relationships, licensing arrangements, and acquired intellectual property. Amortization expense was $8.7 million and $17.3 million for the second quarter and first half of fiscal 2018 , respectively, and $8.1 million and $16.5 million for the second quarter and first half of fiscal 2017, respectively. Based on amortizing assets recognized in our Condensed Consolidated Balance Sheet as of November 26, 2017 , amortization expense is estimated to average $34.0 million for each of the next five years.

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 November 26, 2017 , we had economically hedged certain portions of our anticipated consumption of commodity inputs using derivative instruments with expiration dates through December 2018. 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 November 26, 2017 , we had economically hedged certain portions of our foreign currency risk in anticipated transactions using derivative instruments with expiration dates through August 2018. 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 16 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 November 26, 2017 and May 28, 2017 , $0.9 million representing a right to reclaim cash collateral was 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: November 26, May 28, Prepaid expenses and other current assets $ 4.2 $ 2.3 Other accrued liabilities 2.0 1.3 The following table presents our derivative assets and liabilities, at November 26, 2017 , on a gross basis, prior to the setoff of $0.1 million to total derivative assets and $1.0 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 $ 3.5 Other accrued liabilities $ 1.0 Foreign exchange contracts Prepaid expenses and other current assets 0.8 Other accrued liabilities 1.9 Other Prepaid expenses and other current assets — Other accrued liabilities 0.1 Total derivatives not designated as hedging instruments $ 4.3 $ 3.0 The following table presents our derivative assets and liabilities at May 28, 2017 , on a gross basis, prior to the setoff of $0.5 million to total derivative assets and $1.4 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 $ 2.6 Other accrued liabilities $ 1.4 Foreign exchange contracts Prepaid expenses and other current assets 0.2 Other accrued liabilities 1.1 Other Prepaid expenses and other current assets — Other accrued liabilities 0.2 Total derivatives not designated as hedging instruments $ 2.8 $ 2.7 The location and amount of gains (losses) from derivatives not designated as hedging instruments in our Condensed Consolidated Statements of Earnings were as follows: Derivatives Not Designated as Hedging Instruments Location in Condensed Consolidated Statement of Earnings of Gains Recognized on Derivatives Gains Recognized on Derivatives in Condensed Consolidated Statement of Earnings for the Thirteen Weeks Ended November 26, 2017 November 27, 2016 Commodity contracts Cost of goods sold $ 0.8 $ 1.6 Foreign exchange contracts Cost of goods sold 2.2 1.4 Foreign exchange contracts Selling, general and administrative expense — 2.5 Total gains from derivative instruments not designated as hedging instruments $ 3.0 $ 5.5 Derivatives Not Designated as Hedging Instruments Location in Condensed Consolidated Statement of Earnings of Gains (Losses) Recognized on Derivatives Gains (Losses) Recognized on Derivatives in Condensed Consolidated Statement of Earnings for November 26, 2017 November 27, 2016 Commodity contracts Cost of goods sold $ 1.4 $ 1.2 Foreign exchange contracts Cost of goods sold (5.8 ) 1.5 Foreign exchange contracts Selling, general and administrative expense 0.3 1.3 Total gains (losses) from derivative instruments not designated as hedging instruments $ (4.1 ) $ 4.0 As of November 26, 2017 , our open commodity contracts had a notional value (defined as notional quantity times market value per notional quantity unit) of $81.6 million and $34.2 million for purchase and sales contracts, respectively. As of May 28, 2017 , our open commodity contracts had a notional value of $76.8 million and $73.4 million for purchase and sales contracts, respectively. The notional amount of our foreign currency forward contracts as of November 26, 2017 and May 28, 2017 was $72.8 million and $81.9 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 November 26, 2017 , 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 $0.9 million .

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
SHARE-BASED PAYMENTS	SHARE-BASED PAYMENTS For the second quarter and first half of fiscal 2018 , we recognized total stock-based compensation expense (including stock options, restricted stock units, cash-settled restricted stock units, and performance shares) of $12.3 million and $18.7 million , respectively. For the second quarter and first half of fiscal 2017 , we recognized total stock-based compensation expense of $17.9 million and $32.7 million , respectively. These amounts are inclusive of discontinued operations. Included in the total stock-based compensation expense for the second quarter and first half of fiscal 2018 was expense of $0.1 million and $0.4 million , respectively, related to stock options granted by a subsidiary in the subsidiary's shares to the subsidiary's employees. The expense for these stock options for the second quarter and first half of fiscal 2017 was $0.3 million and $0.2 million , respectively. For the first half of fiscal 2018 , we granted 0.8 million restricted stock units at a weighted average grant date price of $34.09 and 0.5 million performance shares at a weighted average grant date price of $33.82 . Performance shares are granted to selected executives and other key employees with vesting contingent upon meeting various Company-wide performance goals. The performance goal for one-third of the target number of performance shares for the three -year performance period ending in fiscal 2018 (the "2018 performance period") is based on our fiscal 2016 earnings before interest, taxes, depreciation, and amortization ("EBITDA") return on capital. Another one-third of the target number of performance shares granted for the 2018 performance period is based on our fiscal 2017 EBITDA return on capital. The fiscal 2017 EBITDA return on capital target, when set, excluded the results of Lamb Weston. The performance goal for the last one-third of the target number of performance shares granted for the 2018 performance period is based on our fiscal 2018 diluted earnings per share ("EPS") compound annual growth rate ("CAGR"). In addition, for certain participants, all performance shares for the 2018 performance period are subject to an overarching EPS goal that must be met in each fiscal year of the 2018 performance period before any pay out can be made to such participants on the performance shares. The performance goal for one-third of the target number of performance shares for the three -year performance period ending in fiscal 2019 (the "2019 performance period") is based on our fiscal 2017 EBITDA return on capital. The fiscal 2017 EBITDA return on capital target, when set, excluded the results of Lamb Weston. The performance goal for the final two-thirds of the target number of performance shares granted for the 2019 performance period is based on our diluted EPS CAGR, measured over the two -year period ending in fiscal 2019. In addition, for certain participants, all performance shares for the 2019 performance period are subject to an overarching EPS goal that must be met in each fiscal year of the 2019 performance period before any pay out can be made to such participants on the performance shares. The performance goal for the three -year performance period ending in fiscal 2020 is based on our diluted EPS CAGR, measured over the defined performance period. In addition, for certain participants, all performance shares for the 2020 performance period are subject to an overarching EPS goal that must be met in each fiscal year of the 2020 performance period before any pay out can be made to such participants on the performance shares. 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 after the end of the performance period, and only if the participant continues to be employed with the Company through the date of distribution. For awards where performance against the performance target has not been certified, the value of the performance shares is adjusted based upon the market price of our common stock and current forecasted performance against the performance targets at the end of each reporting period and amortized as compensation expense over the vesting period.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE Basic earnings per share is calculated on the basis of weighted average outstanding shares of common stock. Diluted earnings per share is computed on the basis of basic weighted average outstanding shares of common stock adjusted for the dilutive effect of stock options, restricted stock unit awards, and other dilutive securities. The following table reconciles the income and average share amounts used to compute both basic and diluted earnings per share: Thirteen weeks ended Twenty-six weeks ended November 26, November 27, November 26, November 27, Net income available to Conagra Brands, Inc. common stockholders: Income from continuing operations attributable to Conagra Brands, Inc. common stockholders $ 223.1 $ 113.7 $ 375.9 $ 212.1 Income from discontinued operations, net of tax, attributable to Conagra Brands, Inc. common stockholders 0.4 8.4 0.1 96.2 Net income attributable to Conagra Brands, Inc. common stockholders $ 223.5 $ 122.1 $ 376.0 $ 308.3 Less: Increase in redemption value of noncontrolling interests in excess of earnings allocated — 0.3 — 0.8 Net income available to Conagra Brands, Inc. common stockholders $ 223.5 $ 121.8 $ 376.0 $ 307.5 Weighted average shares outstanding: Basic weighted average shares outstanding 406.5 437.7 411.1 438.4 Add: Dilutive effect of stock options, restricted stock unit awards, and other dilutive securities 3.9 3.6 4.0 3.7 Diluted weighted average shares outstanding 410.4 441.3 415.1 442.1 For both the second quarter and first half of fiscal 2018 , there were 1.4 million stock options outstanding that were excluded from the computation of diluted weighted average shares because the effect was antidilutive. For the second quarter and first half of fiscal 2017 , there were 1.5 million and 1.1 million stock options outstanding, respectively, that were excluded from the calculation.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Income tax expense from continuing operations for the second quarter of fiscal 2018 and 2017 was $ 109.5 million and $ 78.4 million , respectively. Income tax expense from continuing operations for the first half of fiscal 2018 and 2017 was $229.5 million and $247.6 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 32.8% and 40.7% for the second quarter of fiscal 2018 and 2017, respectively. The effective tax rate from continuing operations was 37.8% and 53.8% for the first half of fiscal 2018 and 2017, respectively. The effective tax rate in the second quarter of fiscal 2018 reflects the following: • an income tax benefit 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, • additional income tax expense related to state taxes, and • an income tax benefit related to a change in estimate of the income tax effect of undistributed foreign earnings for which the indefinite reinvestment assertion is no longer made. The effective tax rate for the first half of fiscal 2018 reflects the above-cited items, as well as additional expense related to the repatriation of cash from foreign subsidiaries and the tax expense related to undistributed foreign earnings for which the indefinite reinvestment assertion is no longer made. The effective tax rate in the second quarter of fiscal 2017 reflects the following: • an income tax benefit 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, • additional tax expense associated with a change in estimate regarding the tax basis of the Spicetec business that was sold in the first quarter of fiscal 2017, and • additional tax expense associated with non-deductible goodwill in our Mexican business, for which an impairment charge was recognized. The effective tax rate for the first half of fiscal 2017 reflects the above-cited items, as well as 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 in our Canadian business, 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, 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 was $34.0 million as of November 26, 2017 and $39.3 million as of May 28, 2017 . There were no balances included as of either November 26, 2017 or May 28, 2017 , for tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. The gross unrecognized tax benefits excluded related liabilities for gross interest and penalties of $7.1 million and $6.0 million as of November 26, 2017 and May 28, 2017 , respectively. The net amount of unrecognized tax benefits at November 26, 2017 and May 28, 2017 that, if recognized, would impact the Company's effective tax rate was $25.7 million and $31.6 million , respectively. Included in those amounts is $6.6 million and $15.6 million , respectively, that would be reported in discontinued operations. 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 $9.4 million over the next twelve months due to various federal, state, and foreign audit settlements and the expiration of statutes of limitations. As of November 26, 2017 and May 28, 2017 , we had a deferred tax asset of $1.09 billion and $1.08 billion , respectively, that was generated from the capital loss realized on the sale of the Private Brands operations with corresponding valuation allowances of $995.1 million and $990.9 million , respectively, to reflect the uncertainty regarding the ultimate realization of the tax asset. During the first half of fiscal 2018, the balance of the deferred tax asset was adjusted for the impact of state law changes, realization of certain tax attributes, and the settlement of certain tax indemnity claims under the contract terms of the Private Brands sale. Historically, we have not provided U.S. deferred taxes on the cumulative undistributed earnings of our foreign subsidiaries. During the first quarter of fiscal 2018, we decided to repatriate certain cash balances then held in Italy, Canada, Mexico, the Netherlands, and Luxembourg due to the timing of cash flows in connection with certain business acquisition and divestiture activity, as well as forecasted levels of short-term borrowings. We repatriated $151.3 million during the second quarter of fiscal 2018. The cash repatriation resulted in the repatriation of $115.0 million in previously undistributed earnings of our foreign subsidiaries. As a result of the repatriation, we have recognized $11.8 million of income tax expense in the first half of fiscal 2018. In conjunction with this repatriation, we have determined that additional previously undistributed earnings of certain foreign subsidiaries no longer meet the requirements for indefinite reinvestment under applicable accounting guidance and, therefore, recognized an additional $6.8 million of income tax expense in the first half of fiscal 2018. An additional $2.5 million and $6.8 million of income tax expense was recognized in the second quarter and first half of fiscal 2018, respectively, primarily related to a valuation allowance on foreign tax credits generated in the current year and prior periods. We continue to believe the remaining undistributed earnings of our foreign subsidiaries, after taking into account the above transactions, are indefinitely reinvested and therefore have not provided any additional U.S. deferred taxes. On December 22, 2017, the Tax Cuts and Jobs Act was signed into law. We are in the process of evaluating the impact of the recently enacted law to our Condensed Consolidated Financial Statements. The impact is expected to be material to the Condensed Consolidated Financial Statements.

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIES We are a party to various environmental proceedings and litigation, primarily related to our acquisition in fiscal 1991 of 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. Such liabilities include various litigation and environmental proceedings related to businesses divested by Beatrice prior to our acquisition of Beatrice. The litigation proceedings include 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 a predecessor to Beatrice from 1962 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 ordering the creation of a California abatement fund in the amount of $1.15 billion . Liability is joint and several. The Company appealed the Judgment, and on November 14, 2017 the California Court of Appeal for the Sixth Appellate District reversed in part, holding that the defendants were not liable to pay for abatement of homes built after 1950, but affirmed the Judgment as to homes built before 1951 and remanded to the trial court with directions to recalculate the sum to be paid into the abatement fund. The Company has petitioned the California Supreme Court for further review of the decision, which the Company believes to be an unprecedented expansion of current California law. In light of the unsettled nature of California public nuisance law and the ongoing appeal, a loss is considered neither probable nor estimable, and the Company has accordingly not accrued any loss related to this case. In addition, it is not possible to estimate exposure in 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 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 current environmental proceedings associated with Beatrice include litigation and administrative proceedings involving Beatrice's possible status as a potentially responsible party at approximately 40 Superfund, proposed Superfund, or state-equivalent sites (the "Beatrice 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. In the past five years, Beatrice has paid or is in the process of paying its liability share at 31 of these sites. Reserves for these Beatrice environmental proceedings 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 $52.8 million as of November 26, 2017 , a majority of which relates to the Superfund and state-equivalent sites referenced above. During the third quarter of fiscal 2017, a final Remedial Investigation/Feasibility Study was submitted for the Southwest Properties portion of the Wells G&H Superfund site, which is one of the Beatrice sites. The U.S. Environmental Protection Agency (the "EPA") issued a Record of Decision (the "ROD") for the Southwest Properties portion of the site on September 29, 2017, and will subsequently enter into negotiations with potentially responsible parties to determine final responsibility for implementing the ROD. 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. During 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 seeking 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. We filed our Notice of Appeal in September 2016, and the case is awaiting decision by the Nebraska Supreme Court. The appeal will be decided directly by the Nebraska Supreme Court. 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 are party to a number of putative class action lawsuits challenging various product claims made in the Company's product labeling. These matters include Briseno v. ConAgra Foods, Inc., in which it is alleged that the labeling for Wesson ® oils as 100% natural is false and misleading because the oils contain genetically modified plants and organisms. In February 2015, the U.S. District Court for the Central District of California granted class certification to permit plaintiffs to pursue state law claims. The Company appealed to the United States Court of Appeals for the Ninth Circuit, which affirmed class certification in January 2017. The United States Supreme Court declined to review the decision and the case has been remanded to the trial court for further proceedings. While we cannot predict with certainty the results of this or any other legal proceeding, we do not expect this matter to have a material adverse effect on our financial condition, results of operations, or business. We are party to a number of matters challenging the Company's wage and hour practices. These matters include a number of putative class actions consolidated under the caption Negrete v. ConAgra Foods, Inc., et al, pending in the U.S. District Court for the Central District of California, in which the plaintiffs allege a pattern of violations of California and/or federal law at several current and former Company manufacturing facilities across the State of California. While we cannot predict with certainty the results of this or any other legal proceeding, we do not expect this matter to have a material adverse effect on our financial condition, results of operations, or business. In certain limited situations, we guarantee obligations of the Lamb Weston business pursuant to guarantee arrangements that existed prior to the Spinoff and remained in place following completion of the Spinoff until such guarantee obligations are substituted for guarantees issued by Lamb Weston. Such guarantee arrangements are described below. Pursuant to the Separation and Distribution Agreement, dated as of November 8, 2016 (the "Separation Agreement"), between us and Lamb Weston, these guarantee arrangements are deemed liabilities of Lamb Weston that were transferred to Lamb Weston as part of the Spinoff. Accordingly, in the event that we are required to make any payments as a result of these guarantee arrangements, Lamb Weston is obligated to indemnify us for any such liability, reduced by any insurance proceeds received by us, in accordance with the terms of the indemnification provisions under the Separation Agreement. Lamb Weston is a party to a warehouse services agreement with a third-party warehouse provider through July 2035. Under this agreement, Lamb Weston is required to make payments for warehouse services based on the quantity of goods stored and other service factors. We have guaranteed the warehouse provider that we will make the payments required under the agreement in the event that Lamb Weston fails to perform. Minimum payments of $1.5 million per month are required under this agreement. It is not possible to determine the maximum amount of the payment obligations under this agreement. Upon completion of the Spinoff, we recognized a liability for the estimated fair value of this guarantee. As of November 26, 2017 , the amount of this guarantee, recorded in other noncurrent liabilities, was $28.9 million . Lamb Weston is a party to an agricultural sublease agreement with a third party for certain farmland through 2020 (subject, at Lamb Weston's option, to extension for two additional five -year periods). Under the terms of the sublease agreement, Lamb Weston is required to make certain rental payments to the sublessor. We have guaranteed the sublessor Lamb Weston's performance and the payment of all amounts (including indemnification obligations) owed by Lamb Weston under the sublease agreement, up to a maximum of $75.0 million . We believe the farmland associated with this sublease agreement is readily marketable for lease to other area farming operators. As such, we believe that any financial exposure to the company, in the event that we were required to perform under the guaranty, would be largely mitigated. 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 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 November 26, 2017 and May 28, 2017 , the estimated amount by which the put prices exceeded the fair values of the related properties was $50.7 million , of which we had accrued $10.2 million and $8.4 million , respectively. In December 2017, subsequent to the second quarter of fiscal 2018, we purchased a building that had been subject to a put option. We will recognize a net loss of approximately $13 million for the early termination of the associated lease in our third quarter of fiscal 2018. Also in December 2017, we made an offer to purchase another property subject to a put option. We have not entered into a binding legal contract in connection with this offer. However, if our offer is accepted, we may recognize an estimated loss of $30 million to $40 million , upon closing of the transaction, for the early exit of an unfavorable lease contract. If this transaction is completed, we would have one remaining leased building subject to a put option for which the put option price exceeds the estimated fair value by $8.2 million , of which we had accrued $1.0 million , as of November 26, 2017 . 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 of the estimates of any 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.

Retirement Benefits [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. During the second quarter of fiscal 2018, we approved the amendment of our salaried and non-qualified pension plans effective as of December 31, 2017. The amendment will freeze the compensation and service periods used to calculate pension benefits for active employees who participate in the plans. Beginning January 1, 2018, impacted employees will not accrue additional benefit for future service and eligible compensation received under these plans. As a result of the amendment, we were required to remeasure our pension plan liability as of September 30, 2017. In connection with the remeasurement, we updated the effective discount rate assumption from 3.90% to 3.78% . The curtailment and related remeasurement resulted in a net decrease to the underfunded status of the pension plans by $43.5 million with a corresponding benefit within other comprehensive income (loss) for the second quarter of fiscal 2018. In addition, we recorded charges of $3.4 million and $0.7 million reflecting the write-off of actuarial losses in excess of 10% of our pension liability and a curtailment charge, respectively. Components of pension benefit and other postretirement benefit costs are (includes amounts related to discontinued operations): Pension Benefits Thirteen weeks ended Twenty-six weeks ended November 26, November 27, November 26, November 27, Service cost $ 13.2 $ 15.9 $ 25.9 $ 32.6 Interest cost 27.7 29.9 55.9 59.9 Expected return on plan assets (54.6 ) (53.9 ) (108.8 ) (107.7 ) Amortization of prior service cost 0.7 0.7 1.4 1.3 Recognized net actuarial loss 3.4 — 3.4 — Special termination benefits — 1.5 — 1.5 Curtailment loss 0.7 — 0.7 — Benefit cost (benefit) — Company plans (8.9 ) (5.9 ) (21.5 ) (12.4 ) Pension benefit cost — multi-employer plans 4.2 2.8 5.7 5.1 Total benefit cost (benefit) $ (4.7 ) $ (3.1 ) $ (15.8 ) $ (7.3 ) Postretirement Benefits Thirteen weeks ended Twenty-six weeks ended November 26, November 27, November 26, November 27, Service cost $ — $ 0.1 $ — $ 0.1 Interest cost 0.9 1.0 1.8 2.1 Amortization of prior service benefit (0.8 ) (1.6 ) (1.6 ) (3.3 ) Recognized net actuarial loss — 0.1 — 0.2 Total cost (benefit) $ 0.1 $ (0.4 ) $ 0.2 $ (0.9 ) The Company uses a split discount rate (spot-rate approach) for the U.S. plans and certain foreign plans. The spot-rate approach applies separate discount rates for each projected benefit payment in the calculation of pension service and interest cost. The weighted-average discount rates for service and interest costs under the spot-rate approach used for pension benefit cost from May 29, 2017 through September 30, 2017, were 4.19% and 3.26% , respectively. The weighted-average discount rates for service and interest costs subsequent to September 30, 2017 are 4.04% and 3.24% , respectively. During the second quarter and first half of fiscal 2018 , we contributed $2.3 million and $6.1 million , respectively, to our pension plans and contributed $3.0 million and $6.9 million , respectively, 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 $6.8 million to our pension plans for the remainder of fiscal 2018 . We anticipate making further contributions of approximately $11.8 million to our other postretirement plans during the remainder of fiscal 2018 . These estimates are based on ERISA guidelines, current tax laws, plan asset performance, and liability assumptions, which are subject to change. During the second quarter of fiscal 2018, we recorded an expense of $2.1 million related to our expected incurrence of certain multi-employer pension plan withdrawal costs. This expense has been included in restructuring activities.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	6 Months Ended

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 contracts. 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 November 26, 2017 : Level 1 Level 2 Level 3 Net Value Assets: Derivative assets $ 3.3 $ 0.9 $ — $ 4.2 Available-for-sale securities 4.3 — — 4.3 Total assets $ 7.6 $ 0.9 $ — $ 8.5 Liabilities: Derivative liabilities $ — $ 2.0 $ — $ 2.0 Deferred compensation liabilities 53.7 — — 53.7 Total liabilities $ 53.7 $ 2.0 $ — $ 55.7 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 28, 2017 : Level 1 Level 2 Level 3 Net Value Assets: Derivative assets $ 2.0 $ 0.3 $ — $ 2.3 Available-for-sale securities 3.5 — — 3.5 Total assets $ 5.5 $ 0.3 $ — $ 5.8 Liabilities: Derivative liabilities $ — $ 1.3 $ — $ 1.3 Deferred compensation liabilities 47.2 — — 47.2 Total liabilities $ 47.2 $ 1.3 $ — $ 48.5 Certain assets and liabilities, including long-lived assets, goodwill, and cost and equity investments, are measured at fair value on a nonrecurring basis. In the first quarter of fiscal 2018, a charge of $4.7 million was recognized in the Corporate segment for the impairment of certain long-lived assets. The impairment was measured based upon the estimated sales price of the assets. In the second quarter and first half of fiscal 2017, we recognized goodwill impairment charges in the International segment of $43.9 million and $183.1 million , respectively. See Note 7 for discussion of the methodology employed to measure this impairment. We also recognized an impairment of an indefinite-lived brand totaling $24.4 million in the International segment in the first quarter of fiscal 2017.

Segment Reporting [Abstract]
BUSINESS SEGMENTS AND RELATED INFORMATION	BUSINESS SEGMENTS AND RELATED INFORMATION We reflect our results of operations in five reporting segments: Grocery & Snacks, Refrigerated & Frozen, International, Foodservice, and Commercial. 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, 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 included commercially branded and private label food and ingredients, which were sold primarily to commercial, restaurant, foodservice, food manufacturing, and industrial customers. The segment's primary food items included a variety of vegetable, spice, and frozen bakery goods, which were sold under brands such as 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 Twenty-six weeks ended November 26, November 27, November 26, November 27, Net sales Grocery & Snacks $ 900.4 $ 853.2 $ 1,646.2 $ 1,610.4 Refrigerated & Frozen 758.1 740.7 1,373.8 1,345.3 International 220.3 211.4 411.2 406.1 Foodservice 294.6 283.1 546.4 551.1 Commercial — — — 71.1 Total net sales $ 2,173.4 $ 2,088.4 $ 3,977.6 $ 3,984.0 Operating profit Grocery & Snacks $ 199.8 $ 220.2 $ 376.0 $ 400.7 Refrigerated & Frozen 128.5 118.0 230.4 210.2 International 20.2 (26.7 ) 39.1 (175.9 ) Foodservice 47.4 31.9 70.6 53.6 Commercial — (0.5 ) — 202.8 Total operating profit $ 395.9 $ 342.9 $ 716.1 $ 691.4 Equity method investment earnings 20.6 17.2 50.6 30.3 General corporate expense 44.9 113.3 85.1 148.9 Interest expense, net 38.0 54.1 74.4 112.3 Income tax expense 109.5 78.4 229.5 247.6 Income from continuing operations $ 224.1 $ 114.3 $ 377.7 $ 212.9 Less: Net income attributable to noncontrolling interests of continuing operations 1.0 0.6 1.8 0.8 Income from continuing operations attributable to Conagra Brands, Inc. $ 223.1 $ 113.7 $ 375.9 $ 212.1 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 Twenty-six weeks ended November 26, November 27, November 26, November 27, Net derivative gains (losses) incurred $ 3.0 $ 3.0 $ (4.4 ) $ 2.7 Less: Net derivative gains (losses) allocated to reporting segments (4.1 ) 3.8 (5.5 ) 2.8 Net derivative gains (losses) recognized in general corporate expenses $ 7.1 $ (0.8 ) $ 1.1 $ (0.1 ) Net derivative gains (losses) allocated to Grocery & Snacks $ (0.4 ) $ 2.4 $ (1.0 ) $ 2.0 Net derivative gains allocated to Refrigerated & Frozen 0.1 0.7 0.1 0.5 Net derivative gains (losses) allocated to International (3.7 ) 0.2 (4.4 ) 0.2 Net derivative gains (losses) allocated to Foodservice (0.1 ) 0.5 (0.2 ) 0.2 Net derivative losses allocated to Commercial — — — (0.1 ) Net derivative gains (losses) included in segment operating profit $ (4.1 ) $ 3.8 $ (5.5 ) $ 2.8 As of November 26, 2017 , the cumulative amount of net derivative losses from economic hedges that had been recognized in general corporate expenses and not yet allocated to reporting segments was $1.9 million . This amount reflected net losses of $0.6 million incurred during the twenty-six weeks ended November 26, 2017 , as well as net losses of $1.3 million incurred prior to fiscal 2018 . Based on our forecasts of the timing of recognition of the underlying hedged items, we expect to reclassify to segment operating results losses of $1.8 million in fiscal 2018 and losses of $0.1 million in fiscal 2019 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 over time. 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. Total depreciation expense was $55.6 million and $111.7 million for the second quarter and first half of fiscal 2018 , respectively, and $58.2 million and $117.0 million for the second quarter and first half of fiscal 2017 , respectively. Other Information Our largest customer, Wal-Mart Stores, Inc. and its affiliates, accounted for approximately 24% of consolidated net sales in each of the second quarter and first half of fiscal 2018 and 2017 , primarily in the Grocery & Snacks and Refrigerated & Frozen segments. Wal-Mart Stores, Inc. and its affiliates accounted for approximately 28% and 26% of consolidated net receivables as of November 26, 2017 and May 28, 2017 , respectively, primarily in the Grocery & Snacks and Refrigerated & Frozen segments. We offer certain suppliers access to a third-party service that allows them to view our scheduled payments online. The third party service also allows suppliers to finance advances on our scheduled payments at the sole discretion of the supplier and the third party. We have no economic interest in these financing arrangements and no direct relationship with the suppliers, the third party, or any financial institutions concerning this service. All of our accounts payable remain as obligations to our suppliers as stated in our supplier agreements. As of November 26, 2017 , $68.7 million of our total accounts payable is payable to suppliers who utilize this third-party service.

SUMMARY OF SIGNIFICANT ACCOUN24

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Nov. 26, 2017
Accounting Policies [Abstract]
Basis of Consolidation	Basis of Consolidation — The Condensed Consolidated Financial Statements include the accounts of Conagra Brands, 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. On foreign investments we deem to be essentially permanent in nature, we do not provide for taxes on currency translation adjustments arising from converting an investment denominated in 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 will be provided for the related deferred tax liability (asset), if any, resulting from currency translation adjustments.
Cash and cash equivalents	Cash and cash equivalents — Cash and all highly liquid investments with an original maturity of three months or less at the date of acquisition, including short-term time deposits and government agency and corporate obligations, are classified as cash and cash equivalents.
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. 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 July 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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. We adopted this ASU prospectively in fiscal 2018. The adoption of this guidance did not have a material impact to our financial statements. 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 in the process of documenting the impact of the guidance on our current accounting policies and practices in order to identify material differences, if any, that would result from applying the new requirements to our revenue contracts. We continue to make progress on our revenue recognition review and are also in the process of evaluating the impact, if any, on changes to our business processes, systems, and controls to support recognition and disclosure requirements under the new guidance. We continue to evaluate 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 January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities , which addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The effective date for this standard is for fiscal years beginning after December 31, 2017. Early adoption is not permitted except for certain provisions. We do not expect ASU 2016-01 to have a material impact to our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases , Topic 842, 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 this standard 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. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments , which clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows. The effective date for the standard is for fiscal years beginning after December 15, 2017. Early adoption is permitted. We do not expect ASU 2016-15 to have a material impact to our consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash , which provides amendments to current guidance to address the classifications and presentation of changes in restricted cash in the statement of cash flows. The effective date for the standard is for fiscal years beginning after December 15, 2017. Early adoption is permitted. We do not expect ASU 2016-18 to have a material impact to our consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business , which provides a new framework for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The effective date for the standard is for fiscal years beginning after December 15, 2017. Early adoption is permitted. We do not expect ASU 2017-01 to have a material impact to our consolidated financial statements. In March 2017, the FASB issued ASU 2017-07, Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost , which requires companies to present the service cost component of net benefit cost in the same line items in which they report compensation cost. Companies will present all other components of net benefit cost outside operating income, if this subtotal is presented. The effective date for the standard is for fiscal years beginning after December 15, 2017. Early adoption is permitted. We do not expect ASU 2017-07 to have a material impact to our consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities , which improves the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements and make certain targeted improvements to simplify the application of the hedge accounting guidance in current U.S. GAAP. The amendments in this update better align an entity's risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and presentation of hedge results. The effective date for the standard is for fiscal years beginning after December 15, 2018. Early adoption is permitted. We are currently evaluating the impact of our pending adoption of this standard on our consolidated financial statements.
