Accounting Policies [Abstract]	'
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Fiscal Year — The fiscal year of ConAgra Foods, Inc. (“ConAgra Foods”, “Company”, “we”, “us”, or “our”) ends the last Sunday in May. The fiscal years for the consolidated financial statements presented consist of 52-week periods for fiscal years 2014, 2013, and 2012.
	Basis of Consolidation — The 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 consolidated financial statements from the date such determination is made. All significant intercompany investments, accounts, and transactions have been eliminated.
	Investments in Unconsolidated Affiliates — The investments in, and the operating results of, 50%-or-less-owned entities not required to be consolidated are included in the consolidated financial statements on the basis of the equity method of accounting or the cost method of accounting, depending on specific facts and circumstances.
	We review our investments in unconsolidated affiliates for impairment whenever events or changes in business circumstances indicate that the carrying amount of the investments may not be fully recoverable. Evidence of a loss in value that is other than temporary includes, but is not limited to, the absence of an ability to recover the carrying amount of the investment, the inability of the investee to sustain an earnings capacity which would justify the carrying amount of the investment, or, where applicable, estimated sales proceeds which are insufficient to recover the carrying amount of the investment. Management’s assessment as to whether any decline in value is other than temporary is based on our ability and intent to hold the investment and whether evidence indicating the carrying value of the investment is recoverable within a reasonable period of time outweighs evidence to the contrary. Management generally considers our investments in equity method investees to be strategic long-term investments. Therefore, management completes its assessments with a long-term viewpoint. If the fair value of the investment is determined to be less than the carrying value and the decline in value is considered to be other than temporary, an appropriate write-down is recorded based on the excess of the carrying value over the best estimate of fair value of the investment.
	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.
	Inventories — We principally use the lower of cost (determined using the first-in, first-out method) or market for valuing inventories other than merchandisable agricultural commodities. Grain and flour inventories are principally stated at market value.
	Property, Plant and Equipment — Property, plant and equipment are carried at cost. Depreciation has been calculated using the straight-line method over the estimated useful lives of the respective classes of assets as follows:
	Land improvements		1 - 40 years
	Buildings		15 - 40 years
	Machinery and equipment		3 - 20 years
	Furniture, fixtures, office equipment and other		5 - 15 years
	We review property, plant and equipment for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Recoverability of an asset considered “held-and-used” is determined by comparing the carrying amount of the asset to the undiscounted net cash flows expected to be generated from the use of the asset. If the carrying amount is greater than the undiscounted net cash flows expected to be generated by the asset, the asset’s carrying amount is reduced to its estimated fair value. An asset considered “held-for-sale” is reported at the lower of the asset’s carrying amount or fair value.
	Goodwill and Other Identifiable Intangible Assets — Goodwill and other identifiable intangible assets with indefinite lives (e.g., brands or trademarks) are not amortized and are tested annually for impairment of value and whenever events or changes in circumstances indicate the carrying amount of the asset may be impaired. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include deterioration in general economic conditions, adverse changes in the markets in which an entity operates, increases in input costs that have negative effects on earnings and cash flows, or a trend of negative or declining cash flows over multiple periods, among others. The fair value that could be realized in an actual transaction may differ from that used to evaluate the impairment of goodwill and other intangible assets.
	In testing goodwill for impairment, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (more than 50%) that the estimated fair value of a reporting unit is less than its carrying amount. If we elect to perform a qualitative assessment and determine that an impairment is more likely than not, we are then required to perform a quantitative impairment test, otherwise no further analysis is required. We also may elect not to perform the qualitative assessment and, instead, proceed directly to the quantitative impairment test.
	Under the goodwill qualitative assessment, various events and circumstances that would affect the estimated fair value of a reporting unit are identified (similar to impairment indicators above). Furthermore, management considers the results of the most recent two-step quantitative impairment test completed for a reporting unit and compares the weighted average cost of capital between the current and prior years for each reporting unit.
	Under the goodwill two-step quantitative impairment test, the evaluation of impairment involves comparing the current fair value of each reporting unit to its carrying value, including goodwill. The first step of the test compares the carrying value of a reporting unit, including goodwill, with its fair value. We estimate the fair value using level 3 inputs as defined by the fair value hierarchy. Refer to Note 19 for the definition of the levels in the fair value hierarchy. The inputs used to calculate the fair value include a number of subjective factors, such as estimates of future cash flows, estimates of our future cost structure, discount rates for our estimated cash flows, required level of working capital, assumed terminal value, and time horizon of cash flow forecasts. If the carrying value of a reporting unit exceeds its fair value, we complete the second step of the test to determine the amount of goodwill impairment loss, if any, to be recognized. In the second step, we estimate an implied fair value of the reporting unit’s goodwill by allocating the fair value of the reporting unit to all of the assets and liabilities other than goodwill (including any unrecognized intangible assets). The impairment loss is equal to the excess of the carrying value of the goodwill over the implied fair value of that goodwill.
	We implemented organizational changes during the second quarter of fiscal 2014 that resulted in new reporting segments. As a result, we reassigned goodwill to the new reporting units using a relative fair value allocation approach and performed an analysis of the potential impairment of goodwill.
	In the fourth quarter of fiscal 2014, in conjunction with our annual review for impairment, we performed a qualitative analysis of goodwill for each of the reporting units in our segments. As sales and profits for Private Brands continued to be softer than we expected through fiscal 2014, we performed a quantitative analysis of goodwill of our Private Brands segment. Estimating the fair value of individual reporting units requires us to make assumptions and estimates regarding our future plans, industry and economic conditions. Refer to Note 8 for the details of the impairment charges in fiscal 2014.
	In assessing other intangible assets not subject to amortization for impairment, we have the option to perform a qualitative assessment to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of such an intangible asset is less than its carrying amount. If we determine that it is not more likely than not that the fair value of such an intangible asset is less than its carrying amount, then we are not required to perform any additional tests for assessing intangible assets for impairment. However, if we conclude otherwise or elect not to perform the qualitative assessment, then we are required to perform a quantitative impairment test that involves a comparison of the estimated fair value of the intangible asset with its carrying value. If the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.
	In fiscal 2014, we elected to perform a quantitative impairment test for other intangible assets not subject to amortization. The estimates of fair value of intangible assets not subject to amortization are determined using a “relief from royalty” methodology, which is used in estimating the fair value of our brands/trademarks. Discount rate assumptions are based on an assessment of the risk inherent in the projected future cash flows generated by the respective intangible assets. Also subject to judgment are assumptions about royalty rates. Refer to Note 8 for the details of the impairment charges in fiscal 2014.
	Identifiable intangible assets with definite lives (e.g., licensing arrangements with contractual lives or customer relationships) are amortized over their estimated useful lives and tested for impairment whenever events or changes in circumstances indicate the carrying amount of the asset may be impaired. Identifiable intangible assets with definite lives are evaluated for impairment using a process similar to that used in evaluating elements of property, plant and equipment. If impaired, the asset is written down to its fair value.
	Fair Values of Financial Instruments — Unless otherwise specified, we believe the carrying value of financial instruments approximates their fair value.
	Environmental Liabilities — Environmental liabilities are accrued when it is probable that obligations have been incurred and the associated amounts can be reasonably estimated. We use third-party specialists to assist management in appropriately measuring the obligations associated with environmental liabilities. Such liabilities are adjusted as new information develops or circumstances change. We do not discount our environmental liabilities as the timing of the anticipated cash payments is not fixed or readily determinable. Management’s estimate of our potential liability is independent of any potential recovery of insurance proceeds or indemnification arrangements. We do not reduce our environmental liabilities for potential insurance recoveries.
	Employment-Related Benefits — Employment-related benefits associated with pensions, postretirement health care benefits, and workers’ compensation are expensed as such obligations are incurred. The recognition of expense is impacted by estimates made by management, such as discount rates used to value these liabilities, future health care costs, and employee accidents incurred but not yet reported. We use third-party specialists to assist management in appropriately measuring the obligations associated with employment-related benefits.
	We recognize changes in the fair value of pension plan assets and net actuarial gains or losses in excess of 10% of the greater of the market-related value of plan assets or the plan’s projected benefit obligation (“the corridor”) in current period expense annually as of our measurement date, which is our fiscal year-end, or when measurement is required otherwise under generally accepted accounting principles.
	Revenue Recognition — Revenue is recognized when title and risk of loss are transferred to customers upon delivery based on terms of sale and collectability is reasonably assured. Revenue is recognized as the net amount to be received after deducting estimated amounts for discounts, trade allowances, and returns of damaged and out-of-date products. Changes in the market value of inventories of merchandisable agricultural commodities, the fair values of forward cash purchase and sales contracts, and exchange-traded futures and options contracts are recognized in earnings immediately.
	Shipping and Handling — Amounts billed to customers related to shipping and handling are included in net sales. Shipping and handling costs are included in cost of goods sold.
	Marketing Costs — We promote our products with advertising, consumer incentives, and trade promotions. Such programs include, but are not limited to, discounts, coupons, rebates, and volume-based incentives. Advertising costs are expensed as incurred. Consumer incentives and trade promotion activities are recorded as a reduction of revenue or as a component of cost of goods sold based on amounts estimated as being due to customers and consumers at the end of the period, based principally on historical utilization and redemption rates. Advertising and promotion expenses totaled $417.4 million, $466.3 million, and $362.3 million in fiscal 2014, 2013, and 2012, respectively, and are included in selling, general and administrative expenses.
	Research and Development — We incurred expenses of $103.5 million, $93.1 million, and $86.0 million for research and development activities in fiscal 2014, 2013, and 2012, respectively.
	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 postretirement 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. We reclassified $6.0 million of foreign currency translation losses to net income in fiscal 2012 due to our acquisition of a majority interest in Agro Tech Foods Limited ("ATFL") in India and the related remeasurement of our previously held noncontrolling equity interest in ATFL to fair value (see Note 2).
	The following is a rollforward of the balances in accumulated other comprehensive income (loss), net of tax (except for currency translation adjustment):

Foreign Currency Transaction Gains and Losses — We recognized net foreign currency transaction losses from continuing operations of $13.5 million, $0.1 million, and $3.9 million in fiscal 2014, 2013, and 2012, respectively, in selling, general and administrative expenses.
Business Combinations — We use the acquisition method in accounting for acquired businesses. Under the acquisition method, our financial statements reflect the operations of an acquired business starting from the completion of the acquisition. The assets acquired and liabilities assumed are recorded at their respective estimated fair values at the date of the acquisition. Any excess of the purchase price over the estimated fair values of the identifiable net assets acquired is recorded as goodwill.
Reclassifications — Certain prior year amounts have been reclassified to conform with current year presentation.
Use of Estimates — Preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions. These estimates and assumptions affect reported amounts of assets, liabilities, revenues, and expenses as reflected in the consolidated financial statements. Actual results could differ from these estimates.
Recently Issued Accounting Standards — In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which states that entities should present the unrecognized tax benefit as a reduction of the deferred tax asset for a net operating loss ("NOL") or similar tax loss or tax credit carryforward rather than as a liability when the uncertain tax position would reduce the NOL or other carryforward under the tax law. No new disclosures are necessary. This ASU will be effective for the first interim reporting period in fiscal 2015.
In April 2014, the FASB issued ASU 2014-08, Reporting Discontinued Operations and Disclosures of Components of an Entity, which updates the definition of discontinued operations from current U.S. GAAP. Going forward only those disposals of components of an entity that represent a strategic shift that has (or will have) a major effect on an entity's operations and financial results will be reported as discontinued operations in the financial statements. Currently, a component of an entity that is a reportable segment, an operating segment, a reporting unit, a subsidiary, or an asset group is eligible for discontinued operations presentation. Additionally, the existing condition that the entity will not have any significant continuing involvement in the operations of the component after the disposal transaction has been removed. The effective date for the revised standard is for applicable transactions that occur within annual periods beginning on or after December 15, 2014. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. The Company intends to early adopt this standard in the first quarter of fiscal 2015. This will result in the presentation of historical results of our milling business, prior to the creation of the Ardent Mills joint venture, as discontinued operations, beginning in fiscal 2015. Such accounting treatment is precluded prior to the adoption of the new accounting standard.
In May 2014, after our fiscal year end, the FASB issued ASU No. 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 when it becomes effective. The new standard is effective for the Company in our fiscal year 2018. Early application is not permitted. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The standard permits the use of either the retrospective or cumulative effect transition method. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

	ACQUISITIONS
	In September 2013, we acquired frozen dessert production assets from Harlan Bakeries for $39.9 million in cash. The purchase included machinery, operating systems, warehousing/storage, and other assets associated with making frozen fruit pies, cream pies, pastry shells, and loaf cakes. This business is included in the Consumer Foods segment.
	On January 29, 2013, we acquired Ralcorp Holdings, Inc. ("Ralcorp"). The total amount of consideration paid in connection with the acquisition was approximately $4.75 billion, net of cash acquired, plus assumed liabilities. We funded the merger consideration with existing cash on hand, borrowings under a new $1.5 billion senior unsecured Term Loan Facility (the "Term Loan Facility") and net proceeds from the issuance of new senior notes and common stock. The results from our Ralcorp acquisition are reflected principally within the Private Brands segment, and to a lesser extent within Commercial Foods and Consumer Foods.
	The following table summarizes the initial estimated fair values of the assets acquired and liabilities assumed at the acquisition date. We have adjusted amounts to reflect the disposition of Medallion Foods.
		January 29,
		2013
	Assets acquired:
	Cash and cash equivalents	$	320.7
	Other current assets	899
	Current assets held for sale	14.1
	Property, plant and equipment	955.9
	Goodwill	4,360.60
	Brands, trademarks and other intangibles	2,152.70
	Other assets	27.7
	Noncurrent assets held for sale	57.2
	Total assets acquired	$	8,787.90

	Current liabilities held for sale	4.6
	Noncurrent liabilities	3,097.30
	Noncurrent liabilities held for sale	0.1
	Total liabilities assumed	$	3,718.20
	Net assets acquired	$	5,069.70
	As a result of the Ralcorp acquisition, we recognized a total of $4.38 billion of goodwill and $2.17 billion of brands, trademarks and other intangibles, of which $17.5 million and $14.6 million, respectively, have been reclassified as assets held for sale to reflect the disposition of Medallion Foods. Amortizable brands, trademarks and other intangibles totaled $2.03 billion. Indefinite lived brands, trademarks and other intangibles totaled $134.1 million. Of the total goodwill, $397.0 million is deductible for tax purposes. The allocation of goodwill to Private Brands, Consumer Foods, and Commercial Foods was $3.52 billion, $512.0 million, and $350.6 million, respectively. See Note 8 for disclosure of subsequent impairment of related goodwill and indefinite lived brands.
	In August 2012, we acquired the P.F. Chang's® and Bertolli® brands frozen meal business from Unilever for $266.9 million in cash. Approximately $100.1 million of the purchase price was allocated to goodwill and $91.8 million was allocated to brands, trademarks and other intangibles. The amount allocated to goodwill is deductible for tax purposes. This business is included in the Consumer Foods segment.
	In May 2012, we acquired Kangaroo Brands' pita chip operations for $47.9 million in cash. Approximately $20.4 million of the purchase price was allocated to goodwill and $20.8 million was allocated to brands, trademarks and other intangibles. The amount allocated to goodwill is deductible for tax purposes. This business is included in the Private Brands segment.
	In May 2012, we acquired Odom's Tennessee Pride for $96.6 million in cash, plus assumed liabilities. The business manufactures Odom's Tennessee Pride® branded frozen breakfast products and other sausage products. Approximately $32.4 million of the purchase price was allocated to goodwill and $32.8 million was allocated to brands, trademarks and other intangibles. The amount allocated to goodwill is not deductible for tax purposes. This business is included in the Consumer Foods segment.
	In March 2012, we acquired Del Monte Canada for $185.6 million in cash, plus assumed liabilities. The acquisition includes all Del Monte® branded packaged fruit, fruit snacks, and vegetable products in Canada, as well as Aylmer® brand tomato products. Approximately $44.7 million of the purchase price was allocated to goodwill and $80.9 million was allocated to brands, trademarks and other intangibles. The amount allocated to goodwill is not deductible for tax purposes. This business is included in the Consumer Foods segment.
	In November 2011, we acquired National Pretzel Company for $301.9 million in cash, net of cash acquired, plus assumed liabilities. National Pretzel Company is a private brand supplier and branded producer of pretzels and related products. Approximately $178.5 million of the purchase price was allocated to goodwill and $68.2 million was allocated to brands, trademarks and other intangibles. The amount allocated to goodwill is deductible for tax purposes. This business is included in the Private Brands segment.
	In November 2011, we acquired an additional equity interest in ATFL for $4.9 million in cash, net of cash acquired, plus assumed liabilities. ATFL is a publicly traded company in India that markets food and food ingredients to consumers and institutional customers in India. Approximately $130.3 million of the acquisition value was allocated to goodwill and $42.2 million was allocated to trade names. The amount allocated to goodwill is not deductible for income tax purposes. As a result of this additional investment, we own a majority interest (approximately 52%) in ATFL, and we began consolidating the financial statements of ATFL in the third quarter of fiscal 2012. Prior to our acquisition of a majority interest in ATFL, we accounted for our noncontrolling interest (approximately 48% of the outstanding common shares) under the equity method. The fair value of ATFL was determined based upon the closing price of ATFL common shares as of the date of the acquisition of this additional investment. Consolidated financial results of ATFL are included in the Consumer Foods segment in periods subsequent to our acquisition of a majority interest.
	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.
	The following unaudited pro forma financial information presents the combined results of operations as if the acquisitions of Ralcorp, National Pretzel Company, Del Monte Canada, Odom's Tennessee Pride, the Kangaroo Brands' pita chip operations, the P.F. Chang's and Bertolli brands' frozen meals business, and the majority interest in ATFL (collectively, the acquirees) had occurred at the beginning of the year acquired and the preceding year. The acquirees' pre-acquisition results have been added to ConAgra Foods' historical results. The pro forma results contained in the table below include adjustments for amortization of acquired intangibles and depreciation expense, as well as related income taxes.
	The pro forma results exclude selling, general and administrative expenses for the transaction incurred by Ralcorp prior to the acquisition of $84.4 million, including items such as consultant fees, accelerated stock compensation, and other deal costs; selling, general and administrative expenses for the transaction incurred by the Company of $71.4 million, including consultant fees, financing costs, and other deal costs; and cost of goods sold totaling $16.7 million in non-recurring expense related to the fair value of inventory adjustment at the date of acquisition.
	These pro forma results may not necessarily reflect the actual results of operations that would have been achieved, nor are they necessarily indicative of future results of operations.

	RESTRUCTURING ACTIVITIES
	Supply Chain and Administrative Efficiency Plan
	We continue to execute a plan for the integration of Ralcorp and related restructuring activities and during fiscal 2014, our Board of Directors approved an expansion of the scope of the plan to include steps to optimize the entire organization’s supply chain network and improve selling, general and administrative effectiveness and efficiencies, referred to as the Supply Chain and Administrative Efficiency Plan (the “SCAE Plan”). This plan was previously referred to as the Ralcorp Related Restructuring Plan. As a part of this SCAE Plan, we expect to take actions to, among other things, continue the ongoing integration and restructuring of the operations of Ralcorp, optimize manufacturing assets, optimize the Company’s dry distribution and mixing centers, and improve operational effectiveness and reduce overall costs in the Company’s administrative areas. This reporting addresses the estimated amounts or range of amounts for each major type of cost expected to be incurred, and the charges that have or will result in cash outflows. In connection with the SCAE Plan, we expect to incur approximately $325.0 million of charges, which includes $245.4 million of cash charges and $79.6 million of non-cash charges.
	We anticipate that we will recognize the following pre-tax expenses association with the SCAE Plan (amounts include charges recognized in fiscal 2014 and 2013):

	Acquisition-related Restructuring Costs
	During fiscal 2012, we started incurring costs in connection with actions taken to attain synergies when integrating businesses acquired prior to the third quarter of fiscal 2013. These costs, collectively referred to as "acquisition-related restructuring costs", include severance and other costs associated with consolidating facilities and administrative functions. In connection with the acquisition-related restructuring costs, we expect to incur charges of $23.8 million, $15.9 million of which are charges that have resulted or will result in cash outflows and $7.9 million of which are non-cash charges. At the end of fiscal 2014, the acquisition-related restructuring costs were substantially complete.
	During fiscal 2014, we recognized the following pre-tax expenses for acquisition-related restructuring costs, primarily representing impairment of equipment, all within our Consumer Foods segment:
		Total
	Asset impairment	$	3.8
	Other, net	5.6
	Total selling, general and administrative expenses	9.4

	Included in the above results are $15.5 million of charges that have resulted in cash outflows and $7.9 million of non-cash charges.
	Administrative Efficiency Restructuring Plan
	In August 2011, we made a decision to reorganize our Consumer Foods sales function and certain other administrative functions within our Commercial Foods and Corporate reporting segments. These actions, collectively referred to as the "Administrative Efficiency Plan", were intended to improve the efficiency and effectiveness of the affected sales and administrative functions. In connection with the Administrative Efficiency Plan, we have incurred pre-tax cash and non-cash charges of $18.7 million, primarily for severance and costs of employee relocation. At the end of fiscal 2013, the Administrative Efficiency Plan was substantially complete.
We recognized the following pre-tax expenses associated with the Administrative Efficiency Plan in the fiscal 2012 to 2013 timeframe:
	Consumer			Commercial		Corporate			Total

Included in the above results are $16.8 million of charges that have resulted in cash outflows and $1.9 million of non-cash charges.
Network Optimization Plan
During the third quarter of fiscal 2011, our Board of Directors approved a plan designed to optimize our manufacturing and distribution networks. We refer to this plan as the "Network Optimization Plan". The Network Optimization Plan consists of projects that involve, among other things, the exit of certain manufacturing facilities, the disposal of underutilized manufacturing assets, and actions designed to optimize our distribution network. At the end of fiscal 2013, the Network Optimization Plan was substantially complete.
In connection with the Network Optimization Plan, we have incurred pre-tax cash and non-cash charges of $76.7 million. We have recognized expenses associated with the Network Optimization Plan, including but not limited to, impairments of property, plant and equipment, accelerated depreciation, severance and related costs, and plan implementation costs (e.g., consulting and employee relocation). We recognized the following pre-tax expenses associated with the Network Optimization Plan in the fiscal 2011 to fiscal 2013 timeframe:
	Consumer			Commercial		Corporate			Total

2010 Restructuring Plan
During fiscal 2010, our Board of Directors approved a plan related to the long-term production of our meat snack products. The plan provided for the closure of our meat snacks production facility in Garner, North Carolina, and the movement of production to our existing facility in Troy, Ohio.
Also in fiscal 2010, we made a decision to consolidate certain administrative functions from Edina, Minnesota to Naperville, Illinois. We completed the transition of these functions in fiscal 2011. This plan, together with the plan to move production of our meat snacks from Garner, North Carolina to Troy, Ohio, is collectively referred to as the 2010 restructuring plan ("2010 plan").
In connection with the 2010 plan, we incurred pre-tax cash and non-cash charges of $67.3 million cumulatively since inception, of which $2.6 million was recognized in fiscal 2012. By the end of fiscal 2012, the 2010 plan was complete.
Ralcorp Pre-acquisition Restructuring Plans
At the time of its acquisition, Ralcorp had certain initiatives underway designed to optimize its manufacturing and distribution networks. We refer to these actions and the related costs as "Ralcorp Pre-acquisition Restructuring Plans". These plans consisted of projects that involved, among other things, the exit of certain manufacturing facilities. In connection with the Ralcorp Pre-acquisition Restructuring Plans, we have incurred $3.7 million of charges that resulted in cash outflows of $1.9 million and non-cash charges of $1.8 million. In fiscal 2014, we recognized charges of $2.4 million. In fiscal 2013, we recognized charges of $1.3 million. At the end of fiscal 2014, the Pre-acquisition Restructuring Plans costs was substantially complete.

	2017	17.7
	2018	2,655.80

	During the fourth quarter of fiscal 2014, we repaid the entire principal balance of $500.0 million of our 5.875% senior notes, which were due April 15, 2014.
	During fiscal 2013, we issued senior unsecured notes in an aggregate principal amount of $750.0 million. These notes were issued in three tranches of $250.0 million each: 1.35% senior notes due September 10, 2015; 2.10% senior notes due March 15, 2018; and 3.25% senior notes due September 15, 2022.
	During fiscal 2013, in order to finance a portion of our acquisition of Ralcorp, we (i) issued senior unsecured notes in an aggregate principal amount of $3.975 billion, (ii) issued senior unsecured notes in an aggregate principal amount of $716.0 million in exchange for senior notes issued by Ralcorp, (iii) assumed senior notes issued by Ralcorp in an aggregate principal amount of $460.7 million, which were prepaid in fiscal 2013, and (iv) borrowed $1.5 billion under our new Term Loan Facility.
	Our senior unsecured notes in an aggregate principal amount of $3.975 billion were issued in four tranches: 1.3% senior notes due January 25, 2016 in an aggregate principal amount of $750.0 million; 1.9% senior notes due January 25, 2018 in an aggregate principal amount of $1.0 billion; 3.2% senior notes due January 25, 2023 in an aggregate principal amount of $1.225 billion; and 4.65% senior notes due January 25, 2043 in an aggregate principal amount of $1.0 billion. During fiscal 2014, we repaid $63.0 million of 4.65% senior notes due in 2043 prior to maturity, resulting in a net gain of $3.7 million.
	Our senior unsecured notes in an aggregate principal amount of $716.0 million were issued in exchange for senior notes issued by Ralcorp pursuant to our offer to exchange (i) any and all 4.95% senior notes due August 15, 2020 issued by Ralcorp for up to an aggregate principal amount of $300.0 million of new 4.95% senior notes due August 15, 2020 issued by ConAgra Foods and cash and (ii) any and all 6.625% senior notes due August 15, 2039 issued by Ralcorp for up to an aggregate principal amount of $450.0 million of new 6.625% senior notes due August 15, 2039 issued by ConAgra Foods and cash. Our senior unsecured notes in an aggregate principal amount of $716.0 million consist of the following:
	4.95% senior notes due August 2020 (2.92% effective interest rate)	$	282.7
	6.625% senior notes due August 2039 (4.86% effective interest rate)	433.3
	Senior notes issued by Ralcorp in an aggregate principal amount of $33.9 million were not exchanged and remain outstanding, consisting of 4.95% senior notes issued by Ralcorp due August 15, 2020 in an aggregate principal amount of $17.2 million (with an effective interest rate of 2.83%) and 6.625% senior notes issued by Ralcorp due August 15, 2039 in an aggregate principal amount of $16.7 million (with an effective interest rate of 4.82%) (collectively, the "Ralcorp Notes"). The Ralcorp Notes are included in our Consolidated Balance Sheets at May 25, 2014.
	During fiscal 2013, we offered to purchase for cash any and all 7.29% senior notes due August 15, 2018 issued by Ralcorp, floating rate senior notes due August 15, 2018 issued by Ralcorp, and 7.39% senior notes due August 15, 2020 issued by Ralcorp, in a total aggregate principal amount of $664.5 million. Pursuant to this offer, we purchased senior notes issued by Ralcorp in a total aggregate principal amount of $631.5 million. Ralcorp's 7.29% senior notes due August 15, 2018 in an aggregate principal amount of $33.0 million were not tendered for purchase and remained outstanding (the "Ralcorp Discharged Notes"). During fiscal 2013, we paid $44.8 million, consisting of principal, interest, and contractual amounts payable to satisfy and discharge the Ralcorp Discharged Notes, which were satisfied and discharged by the trustee during fiscal 2013. We recognized a charge of $1.3 million as a cost of early retirement of debt.
	Upon our acquisition of Ralcorp, we assumed senior notes issued by Ralcorp in an aggregate principal amount of $460.7 million (the "Ralcorp Callable Notes"), and gave notice of our intent to prepay them during the third quarter of fiscal 2013. During the fourth quarter of fiscal 2013, we prepaid the Ralcorp Callable Notes at the contractually determined value of $562.5 million. This did not result in a significant gain or loss.
	During fiscal 2013, we borrowed $1.5 billion under our unsecured Term Loan Facility with a syndicate of banks. We are required to repay borrowings under the Term Loan Facility during the term of the facility in equal quarterly installments of 2.5% per quarter commencing on June 1, 2013, with the remainder of the borrowings to be paid on the maturity date of the facility, unless prepaid prior to such date in accordance with the terms of the Term Loan Facility. During fiscal 2013, we prepaid $600.0 million of the $1.5 billion borrowings and recognized a charge of $6.2 million as a cost of early retirement of debt. The Term Loan Facility matures on January 29, 2018. We elected to base the interest rate of the borrowings on LIBOR plus 1.75%. As of May 25, 2014, the total interest rate on our borrowings was 1.902%. Certain of our wholly-owned domestic subsidiaries may, under certain circumstances, be required to guarantee our obligations under the Term Loan Facility.
	In connection with the aforementioned financing for the Ralcorp acquisition, we capitalized $52.1 million of debt issuance costs and recognized expense of $27.3 million in related fees during fiscal 2013.
	During fiscal 2012, we repaid the entire principal balance of $342.7 million of our 6.75% senior notes, which were due September 15, 2011.
	Our most restrictive debt agreements (the revolving credit facility and our Term Loan Facility) require that our consolidated funded debt not exceed 70% of our consolidated capital base, and that our fixed charges coverage ratio be greater than 1.75 to 1.0 on a four-quarter rolling basis. At May 25, 2014, we were in compliance with our debt covenants.
	Net interest expense consists of:
		2014			2013			2012
	Long-term debt	$	393.8		$	284		$	213.2
	Short-term debt	1.5			0.7			0.3
	Interest income	(2.5		)	(3.0		)	(4.0		)
	Interest capitalized	(13.8		)	(6.1		)	(5.5		)
		$	379		$	275.6		$	204
	Interest paid from continuing operations was $395.7 million, $215.6 million, and $211.9 million in fiscal 2014, 2013, and 2012, respectively.
	Our net interest expense in fiscal 2014, 2013, and 2012 was reduced by $8.6 million, $9.2 million, and $9.9 million, respectively, due to the impact of the interest rate swap contracts entered into in fiscal 2010. The interest rate swaps effectively changed our interest rates on the senior long-term debt instruments maturing in fiscal 2012 and 2014 from fixed to variable. During fiscal 2011, we terminated the interest rate swap contracts and received proceeds of $31.5 million. The cumulative adjustment to the fair value of the debt instruments that were hedged (the effective portion of the hedge) was amortized as a reduction of interest expense over the lives of the debt instruments (through fiscal 2014).
	During fiscal 2014, we entered into interest rate swap contracts to hedge the fair value of certain of our senior long-term debt instruments maturing in fiscal 2019 and 2020, effectively converting interest on this debt from fixed rate to floating rate. These swaps, which are designated as fair value hedges, reduced our interest expense by $4.1 million in fiscal 2014.
	As a result of our acquisition of Ralcorp, the senior unsecured notes issued in exchange for senior notes issued by Ralcorp of $716.0 million and the senior notes issued by Ralcorp that remain outstanding of $33.9 million were recorded at fair value. The combined fair value adjustment on these notes was $163.8 million and is being amortized within interest expense over the life of the respective notes. Our net interest expense in fiscal 2014 and 2013 was reduced by $7.1 million and $2.2 million, respectively, as a result of this amortization.
	Subsequent to our fiscal year end, in June 2014, we repaid $350.0 million of the principal amount outstanding under the term loan facility with a portion of the proceeds received in connection with the formation of Ardent Mills. We paid the remaining outstanding principal balance of $550.0 million under the term loan facility in July 2014, and terminated the facility, with a portion of the proceeds from the formation of Ardent Mills and approximately $330 million of borrowings under our commercial paper program.

	CREDIT FACILITIES AND BORROWINGS
	At May 25, 2014, we had a $1.50 billion multi-year revolving credit facility with a syndicate of financial institutions that matures in September 2018. The multi-year facility has historically been used principally as a back-up facility for our commercial paper program. As of May 25, 2014, there were no outstanding borrowings under the credit facility. Borrowings under the multi-year facility, based on our fiscal year-end credit rating, bear interest at 1.3% over LIBOR and may be prepaid without penalty. The multi-year revolving credit facility requires us to repay borrowings if our consolidated funded debt exceeds 70% of our consolidated capital base during the first four quarters commencing on January 29, 2014, then 65% thereafter, or if our fixed charges coverage ratio is less than 1.75 to 1.0 on a four-quarter rolling basis. As of May 25, 2014, we were in compliance with the credit agreement’s financial covenants.
	We finance our short-term liquidity needs with bank borrowings, commercial paper borrowings, and bankers’ acceptances. As of May 25, 2014, we had $137.0 million outstanding under our commercial paper program at an average weighted interest rate of 0.40%. As of May 26, 2013, we had $185.0 million outstanding under our commercial paper program at an average weighted interest rate of 0.42%.

	Medallion Foods
	In the fourth quarter of fiscal 2014, we completed the sale of a small snack business, Medallion Foods, for $32.0 million in cash. The business results were previously reflected in the Private Brands segment. We reflected the results of these operations as discontinued operations for all periods presented. The assets and liabilities of the discontinued business have been reclassified as assets and liabilities held for sale within our Consolidated Balance Sheets for all periods presented prior to divestiture. We recognized a pre-tax loss of $5.8 million ($3.5 million after-tax) on the sale of this business in the fourth quarter of fiscal 2014. In the third quarter of fiscal 2014, we recognized an impairment charge related to allocated amounts of goodwill and intangible assets, totaling $25.4 million ($15.2 million after-tax), in anticipation of this divestiture.
	Lightlife® Operations
	In the second quarter of fiscal 2014, we completed the sale of the assets of the Lightlife® business for $54.7 million in cash. This business produced and sold vegetarian-based burgers, hot dogs, and other meatless frozen and refrigerated items. The results of this business were previously reflected in the Consumer Foods segment. We reflected the results of these operations as discontinued operations for all periods presented. We recognized a pre-tax gain of $32.1 million ($19.8 million after-tax) on the sale of this business in fiscal 2014. The assets of the discontinued Lightlife business have been reclassified as assets held for sale within our Consolidated Balance Sheets for all periods presented prior to divestiture.

	Formation of Ardent Mills
	On May 25, 2014, we sold three flour milling facilities located in Oakland, California, Saginaw, Texas, and New Prague, Minnesota, to Miller Milling Company LLC for a total cash consideration of $162.4 million. This amount is included within the receivable on sale of flour milling assets line of our Consolidated Balance Sheet. We recognized a pre-tax gain of $90.3 million ($55.7 million after-tax) during the fourth quarter of fiscal 2014. The related assets have been reclassified as assets held for sale within our Consolidated Balance Sheets for all periods presented prior to divestiture. These mills were divested pursuant to an agreement with the U.S. Department of Justice related to the previously announced formation of the Ardent Mills flour milling joint venture, which was completed subsequent to the end of fiscal 2014. On May 29, 2014, subsequent to the end of fiscal 2014, the Company, Cargill, Incorporated ("Cargill"), and CHS Inc. ("CHS") (collectively, the “Owners”), completed the formation of Ardent Mills. In connection with the closing of the Ardent Mills joint venture, the Company received total cash consideration of $565.3 million before closing costs and working capital adjustments (of which $162.4 million was recognized in fiscal 2014 for the sale of the three mills), and a 44% interest in the Ardent Mills joint venture. We expect to recognize a pre-tax gain of approximately $625 million in the first quarter of fiscal 2015 in connection with the formation of the Ardent Mills joint venture.
	The Company has allocated the net cash proceeds primarily towards debt reduction.
	Other Assets Held for Sale
	During the third quarter of fiscal 2014, we began actively marketing for sale an onion processing facility and farmland previously acquired from an onion products supplier. These assets are held within our Commercial Foods segment. During the fourth quarter of fiscal 2014, we sold the farmland for proceeds of $15.1 million. We recognized a pre-tax gain of $5.1 million ($3.2 million after-tax) on the sale of this land in the fourth quarter of fiscal 2014. The processing facility assets have been reclassified as assets held for sale within our Consolidated Balance Sheets for all periods presented.

	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 May 25, 2014, the price at which Ochoa had the right to put its equity interest to us was $41.9 million. This amount is presented within other noncurrent liabilities in our 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.
	We hold a promissory note from Lamb Weston BSW, the balance of which was $36.1 million at May 25, 2014. The promissory note is due in December 2015. The promissory note is currently accruing interest at a rate of LIBOR plus 200 basis points with a floor of 3.25%. In addition, as of May 25, 2014, we provided lines of credit of up to $15.0 million to Lamb Weston BSW. Borrowings under the lines of credit bear interest at a rate of LIBOR plus 200 basis points with a floor of 3.25%. The amounts owed by Lamb Weston BSW to the Company are not reflected in our Consolidated Balance Sheets, as they are eliminated in consolidation.
	Our variable interests in Lamb Weston BSW include an equity investment in the venture, the options, the promissory note, certain fees paid to us by Lamb Weston BSW for sales and marketing services, the contingent obligation related to production shortfalls, and the lines of credit advanced to Lamb Weston BSW. 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 the promissory note extended to the venture, the amount, if any, advanced under the lines of credit, 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 these variable interest entities, we reflected the following in our Consolidated Balance Sheets:
		May 25,		May 26,
		2014		2013
	Cash and cash equivalents	$	17.7	$	8.9
	Receivables, less allowance for doubtful accounts	19.1		16.4
	Inventories	1.4		1.4
	Prepaid expenses and other current assets	0.3		0.4
	Property, plant and equipment, net	51.8		54.8
	Goodwill	18.8		18.8
	Brands, trademarks and other intangibles, net	6.7		7.5
	Total assets	$	115.8	$	108.2
	Accounts payable	$	11.7	$	8.9
	Accrued payroll	0.5		0.6
	Other accrued liabilities	0.6		0.7
	Other noncurrent liabilities (minority interest)	33.3		30.7
	Total liabilities	$	46.1	$	40.9
	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, other than as a secured lender under the promissory note and lines of credit.
	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 Consolidated Balance Sheets, based upon the equity method of accounting. The balance of our investment was $12.6 million and $15.2 million at May 25, 2014 and May 26, 2013, 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 $25.4 million and term borrowings from banks of $42.8 million as of May 25, 2014. 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, representing our only variable interest in these lessor entities. These leases are accounted for as operating leases, and accordingly, there are no material assets or liabilities associated with these entities included in our Consolidated Balance Sheets. We have no material exposure to loss from our variable interests in these entities. 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.

		$	3,436.60		$	230.8	$	3,525.60		$	122
	We implemented organizational changes during the second quarter of fiscal 2014 that resulted in new reporting segments. As a result, we reassigned goodwill to the new reporting units using a relative fair value allocation approach and performed a goodwill impairment analysis, which did not identify any potential impairments.
	In the fourth quarter of fiscal 2014, in conjunction with our annual review for impairment, we performed a qualitative analysis of goodwill for each of the reporting units in our segments. Because sales and profits for Private Brands continued to fall below our expectations throughout fiscal 2014 and following preparation of plans for the business for fiscal 2015, we performed a quantitative analysis of goodwill of our Private Brands 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 each reporting unit within the Private Brands segment 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 approximately 8.3% and 3%, respectively, to calculate the present value of estimated future cash flows. We then compared the estimated fair value of each reporting unit to the respective 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 for five of our reporting units within the Private Brands segment. With the assistance of a third-party valuation specialist, we estimated the fair value of the assets and liabilities of each of these reporting units, in order to determine the implied fair value of goodwill of each reporting unit. We recognized impairment charges for the difference between the implied fair value of goodwill and the historical carrying value of goodwill within each reporting unit. Accordingly, during the fourth quarter of fiscal 2014, we recorded a $602.2 million charge for the impairment of goodwill. The following reporting units within Private Brands were impacted: $66.4 million in Bars and Coordinated, $154.6 million in Cereal, $94.2 million in Pasta, $231.6 million in Snacks, and $55.4 million in Retail Bakery.
	In the case of three of our reporting units within the Private Brands segment; Pasta, Snacks, and Retail Bakery, the estimated fair value of certain amortizing intangible assets (customer relationships) used in step two of our impairment analysis was substantially less than the carrying value of those assets and, as a result, the carrying value of the Pasta, Snacks, and Retail Bakery reporting units exceeded the estimated fair values of those reporting units, even after the previously described goodwill impairment charges were recorded. The carrying value of the Private Brands amortizing intangible assets are expected to be recovered over their remaining lives (on an undiscounted basis) and, accordingly, no impairments were required to be recognized.
	Following the impairment charges recorded in fiscal 2014, the carrying value of goodwill in our Private Brands reporting units included $328.7 million for Bars and Coordinated, $464.4 million for Cereal, $752.1 million for Pasta, $816.2 million for Snacks, $717.1 million for Retail Bakery, and $136.1 million for Condiments. If the future performance of one or more of the reporting units within the Private Brands segment falls short of our expectations or if there are significant changes in risk-adjusted discount rates due to changes in market conditions, we could be required to recognize additional, material impairment charges in future periods.
	In fiscal 2014, we also elected to perform a quantitative impairment test for non-amortizing intangible assets, which are comprised of brands and trademarks. We recognized impairment charges of $72.5 million in our Consumer Foods segment, primarily for our Chef Boyardee® brand and a $3.2 million impairment charge in our Private Brands segment for two small brands. We also recognized a $3.2 million impairment charge for an amortizable technology license in Corporate expenses in fiscal 2014.
	In the fourth quarter of fiscal 2014, we completed the sale of Medallion Foods within the Private Brands segment. Related allocated goodwill and amortizing intangible assets of $17.5 million and $14.4 million , respectively, were reclassified to noncurrent assets held for sale. During fiscal 2014, we recognized impairments of $17.5 million and $7.9 million, of the allocated goodwill and amortizing intangible assets, respectively, which are reflected in discontinued operations.
	Amortizing intangible assets, carrying a weighted average life of approximately 23 years, are principally composed of customer relationships, licensing arrangements, and intellectual property. For fiscal 2014, 2013, and 2012, we recognized amortization expense of $111.4 million, $55.7 million, and $20.8 million, respectively. Based on amortizing assets recognized in our Consolidated Balance Sheet as of May 25, 2014, amortization expense is estimated to average $108.5 million for each of the next five years, with a high expense of $109.2 million in fiscal year 2015 and decreasing to a low expense of $107.0 million in fiscal year 2019.

EARNINGS PER SHARE	'
	EARNINGS PER SHARE
	Basic earnings per share is calculated on the basis of weighted average outstanding common shares. Diluted earnings per share is computed on the basis of basic weighted average outstanding common shares 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:
		2014		2013			2012
	Net income available to ConAgra Foods, Inc. common stockholders:
	Income from continuing operations attributable to ConAgra Foods, Inc. common stockholders	$	299	$	774.6		$	461.4
	Income (loss) from discontinued operations, net of tax, attributable to ConAgra Foods, Inc. common stockholders	4.1		(0.7		)	6.5
	Net income attributable to ConAgra Foods, Inc. common stockholders	$	303.1	$	773.9		$	467.9

	Net income available to ConAgra Foods, Inc. common stockholders	$	301.4	$	772.3		$	466.4
	Weighted average shares outstanding:

	Diluted weighted average shares outstanding	427.5		417.6			418.3
	At the end of fiscal 2014 and 2012, there were 3.1 million and 11.3 million stock options outstanding, respectively, that were excluded from the computation of shares contingently issuable upon exercise of the stock options because exercise prices exceeded the average market value of our common stock during the period. At the end of fiscal 2013, there were no stock options outstanding that were excluded from the computation of shares contingently issuable upon exercise of the stock options.

	SHARE-BASED PAYMENTS
	In accordance with stockholder-approved plans, we issue share-based payments under various stock-based compensation arrangements, including stock options, restricted stock units, cash-settled restricted stock units, performance shares, and other share-based awards. In accordance with stockholder-approved plans, we issue share-based payments under various stock-based compensation arrangements, including stock options, restricted stock units, cash-settled restricted stock units, performance shares, and other share-based awards. The shares to be delivered under the plan may consist, in whole or part, of treasury stock or authorized but unissued stock, not reserved for any other purpose.
	On September 25, 2009, the stockholders approved the ConAgra Foods 2009 Stock Plan, which authorized the issuance of up to 29.5 million shares of ConAgra Foods common stock. At May 25, 2014, approximately 12.2 million shares were reserved for granting additional options, restricted stock units, cash-settled restricted stock units, performance shares, or other share-based awards.
	Stock Option Plan
	We have stockholder-approved stock option plans that provide for granting of options to employees for the purchase of common stock at prices equal to the fair value at the date of grant. Options become exercisable under various vesting schedules (typically three to five years) and generally expire seven to ten years after the date of grant.
	The fair value of each option is estimated on the date of grant using a Black-Scholes option-pricing model with the following weighted average assumptions for stock options granted:
		2014		2013		2012
	Expected volatility (%)	21.13		22.95		22.89
	Dividend yield (%)	3.24		3.77		3.97
	Risk-free interest rates (%)	1.37		0.57		1.38
	Expected life of stock option (years)	4.91		4.8		4.75
	The expected volatility is based on the historical market volatility of our stock over the expected life of the stock options granted. The expected life represents the period of time that the awards are expected to be outstanding and is based on the contractual term of each instrument, taking into account employees’ historical exercise and termination behavior.
	A summary of the option activity as of May 25, 2014 and changes during the fiscal year then ended is presented below:
	Options	Number			Weighted		Average		Aggregate
		of Options			Average		Remaining		Intrinsic
		(in Millions)			Exercise		Contractual		Value (in

	Outstanding at May 26, 2013	19.9			$	23.73

	Exercisable at May 25, 2014	12.1			$	23.23	2.99		$	101
	We recognize compensation expense using the straight-line method over the requisite service period. During fiscal 2014, 2013, and 2012, the Company granted 3.6 million options, 3.9 million options, and 4.1 million options, respectively, with a weighted average grant date value of $4.71, $2.93, and $3.26, respectively. The total intrinsic value of options exercised was $46.9 million, $77.2 million, and $41.5 million for fiscal 2014, 2013, and 2012, respectively. The closing market price of our common stock on the last trading day of fiscal 2014 was $31.61 per share.
	Compensation expense for stock option awards totaled $12.6 million, $12.8 million, and $15.4 million for fiscal 2014, 2013, and 2012, respectively. The tax benefit related to the stock option expense for fiscal 2014, 2013, and 2012 was $4.7 million, $4.8 million, and $5.7 million, respectively.
	At May 25, 2014, we had $11.6 million of total unrecognized compensation expense, net of estimated forfeitures, related to stock options that will be recognized over a weighted average period of 1.3 years.
	Cash received from option exercises for the fiscal years ended May 25, 2014, May 26, 2013, and May 27, 2012 was $104.6 million, $259.8 million, and $217.8 million, respectively. The actual tax benefit realized for the tax deductions from option exercises totaled $17.4 million, $28.7 million, and $15.4 million for fiscal 2014, 2013, and 2012, respectively.
	Share Unit Plans
	In accordance with stockholder-approved plans, we issue stock under various stock-based compensation arrangements, including restricted stock units, cash-settled restricted stock units, and other share-based awards (“share units”). These awards generally have requisite service periods of three years. Under each arrangement, stock is issued without direct cost to the employee. We estimate the fair value of the share units based upon the market price of our stock at the date of grant. Certain share unit grants do not provide for the payment of dividend equivalents to the participant during the requisite service period (vesting period). For those grants, the value of the grants is reduced by the net present value of the foregone dividend equivalent payments. We recognize compensation expense for share unit awards on a straight-line basis over the requisite service period. All cash-settled restricted stock units are marked-to-market and presented within other noncurrent liabilities in our Consolidated Balance Sheets. The compensation expense for our stock-settled share unit awards totaled $26.1 million, $26.7 million, and $25.5 million for fiscal 2014, 2013, and 2012, respectively. The tax benefit related to the stock-settled share unit award compensation expense for fiscal 2014, 2013, and 2012 was $9.8 million, $9.9 million, and $9.5 million, respectively. The compensation expense for our cash-settled share unit awards totaled $12.4 million and $8.0 million for fiscal 2014 and 2013, respectively. The tax benefit related to the cash-settled share unit award compensation expense for fiscal 2014 and 2013 was $4.6 million and $3.0 million, respectively.
	The following table summarizes the nonvested share units as of May 25, 2014 and changes during the fiscal year then ended:
		Stock-settled					Cash-settled
	Share Units	Share Units			Weighted		Share Units			Weighted

	During fiscal 2014, 2013, and 2012, we granted 0.9 million, 1.0 million, and 1.8 million stock-settled share units, respectively, with a weighted average grant date value of $36.22, $25.59, and $26.11, respectively. During fiscal 2014 and 2013 we granted 0.8 million and 0.9 million cash-settled share units, respectively, with a weighted average grant date value of $36.89 and $24.74, respectively.
	The total intrinsic value of stock-settled share units vested was $46.4 million, $24.3 million, and $23.2 million during fiscal 2014, 2013, and 2012, respectively.
	At May 25, 2014, we had $43.7 million of total unrecognized compensation expense, net of estimated forfeitures, related to share unit awards that will be recognized over a weighted average period of 1.8 years.
	Performance-Based Share Plan
	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 2014 and 2015 are based upon our operating cash flow return on operations, a measure of operating cash flow as a percentage of invested capital, and revenue growth, each measured over a defined performance period. The performance goals for the performance period ending in fiscal 2016 are based upon our earnings before interest, taxes, depreciation, and amortization ("EBITDA") return on capital, and revenue growth, each measured over the defined performance period. The awards actually earned will range from zero to two hundred twenty percent of the targeted number of performance shares for each of the performance periods. A payout equal to 25 percent of approved target incentive is required to be paid out if we achieve a threshold level of cash flow return on operations for the performance periods ending in fiscal 2014 and 2015, and a threshold level of EBITDA return on capital for the performance period ending in fiscal 2016. 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 at the end of each reporting period and amortized as compensation expense over the vesting period.
	A summary of the activity for performance share awards as of May 25, 2014 and changes during the fiscal year then ended is presented below:
	Performance Shares	Shares			Weighted
		(in  Millions)			Average
					Grant-Date
					Fair Value
	Nonvested performance shares at May 26, 2013	1.25			$	24.24
	Granted	0.4			$	34.07
	Adjustments for performance results attained	(0.13	)		$	21.46
	Vested/Issued	(0.28	)		$	21.46
	Forfeited	(0.07	)		$	29.39
	Nonvested performance shares at May 25, 2014	1.17			$	28.27
	The compensation expense for our performance share awards totaled $6.5 million, $19.9 million, and $0.8 million for fiscal 2014, 2013, and 2012, respectively. The tax benefit related to the compensation expense for fiscal 2014, 2013, and 2012 was $2.4 million, $7.4 million, and $0.3 million, respectively.
	The total intrinsic value of share units vested (including shares paid in lieu of dividends) during fiscal 2014 and 2012 was $10.4 million and $16.0 million, respectively.
	Based on estimates at May 25, 2014, the Company had $9.1 million of total unrecognized compensation expense, net of estimated forfeitures, related to performance shares that will be recognized over a weighted average period of 1.7 years.
	Accounting guidance requires the benefits of tax deductions in excess of recognized compensation expense to be reported as a financing cash flow, rather than as an operating cash flow in our Consolidated Statement of Cash Flows. As a result, in fiscal 2014, 2013, and 2012, our net operating cash flows decreased and our net financing cash flows increased by approximately $18.9 million, $21.3 million, and $8.7 million, respectively.

	At May 25, 2014 and May 26, 2013, net deferred tax assets of $109.2 million and $177.0 million, respectively, were included in prepaid expenses and other current assets. At May 25, 2014 and May 26, 2013, net deferred tax liabilities of $1.44 billion and $1.54 billion, respectively, were included in other noncurrent liabilities.
	The liability for gross unrecognized tax benefits at May 25, 2014 was $84.9 million, excluding a related liability of $29.6 million for gross interest and penalties. Included in the balance at May 25, 2014 are $8.2 million of 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. As of May 26, 2013, our gross liability for unrecognized tax benefits was $100.0 million, excluding a related liability of $30.4 million for gross interest and penalties. Included in the balance at May 26, 2013 are $8.0 million of tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. Interest and penalties recognized in the Consolidated Statement of Earnings was a benefit of $1.3 million in fiscal 2014, $1.2 million in fiscal 2013 and $0.6 million in fiscal 2012.
	The net amount of unrecognized tax benefits at May 25, 2014 and May 26, 2013 that, if recognized, would favorably impact our effective tax rate was $50.8 million and $61.8 million, respectively.
	We accrue interest and penalties associated with uncertain tax positions as part of income tax expense.
	We conduct business and file tax returns in numerous countries, states, and local jurisdictions. The U.S. Internal Revenue Service (“IRS”) has completed its audit for tax years through fiscal 2013 and all resulting significant items for fiscal 2013 and prior years have been settled with the IRS. Other major jurisdictions where we conduct business generally have statutes of limitations ranging from 3 to 5 years.
	We estimate that it is reasonably possible that the amount of gross unrecognized tax benefits will decrease by up to $7 million over the next twelve months due to various state and foreign audit settlements and the expiration of statutes of limitations.
	The change in the unrecognized tax benefits for the year ended May 25, 2014 was:
	Beginning balance on May 26, 2013	$	100
	Increases from positions established during prior periods	15.4
	Decreases from positions established during prior periods	(17.0		)
	Increases from positions established during the current period	5.8
	Decreases relating to settlements with taxing authorities	(11.3		)
Reductions resulting from lapse of applicable statute of limitation	(7.6		)
Other adjustments to liability	(0.4		)
Ending balance on May 25, 2014	$	84.9
We have approximately $74.6 million of foreign net operating loss carryforwards ($50.8 million will expire between fiscal 2015 and 2035 and $23.8 million have no expiration dates) and $22.1 million of Federal net operating loss carryforwards which expire between fiscal 2015 and 2024. Included in net deferred tax liabilities are $46.5 million of tax effected state net operating loss carryforwards which expire in various years ranging from fiscal 2015 to 2034. Substantially all of our foreign tax credits will expire in fiscal 2018. State tax credits of approximately $30.1 million will expire in various years ranging from fiscal 2015 to 2019.
We have recognized a valuation allowance for the portion of the net operating loss carryforwards, tax credit carryforwards, and other deferred tax assets we believe are not more likely than not to be realized. The net impact on income tax expense related to changes in the valuation allowance for fiscal 2014 was a benefit of $1.5 million. For fiscal 2013 and 2012, changes in the valuation allowance were a charge of $1.1 million and a benefit of $7.1 million, respectively. The current year change principally relates to decreases to the valuation allowances for state and foreign net operating losses and credits.
As of May 25, 2014, undistributed earnings of the Company’s foreign subsidiaries amounted to approximately $560 million. Those earnings are considered to be indefinitely reinvested and accordingly, no U.S. federal income taxes have been provided thereon. We have not provided U.S. deferred taxes on cumulative earnings of non-U.S. affiliates and associated companies that the Company considers to be reinvested indefinitely. It is not practicable to estimate the amount of U.S. income taxes that would be incurred in the event that we were to repatriate the cumulative earnings of non-U.S. affiliates and associated companies. Deferred taxes are provided for earnings of non-U.S. affiliates and associated companies when we determine that such earnings are no longer indefinitely reinvested.

	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 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, 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 in the form of medical monitoring for elevated levels of lead in blood. In California, a number of cities and counties have 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 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 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 Company cannot absolutely assure that the final resolution of this matter 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 36 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 34 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 reserves for Beatrice-related environmental matters totaled $61.6 million as of May 25, 2014, 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 guarantee certain leases resulting from the 2002 divestiture of our fresh beef and pork operations. The remaining terms of these arrangements do not exceed 2 years and the maximum amount of future payments we have guaranteed was $5.4 million as of May 25, 2014.
	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 May 25, 2014, the amount of supplier loans we have effectively guaranteed was $34.4 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.
	We were a party to a supply agreement with an onion processing company where we had guaranteed, under certain conditions, repayment of a secured loan (the "Secured Loan") of this onion products supplier to the onion products supplier's lender. The amount of our guarantee was $25.0 million. During the fourth quarter of fiscal 2012, we received notice from the lender that the onion products supplier had defaulted on the Secured Loan and we exercised our option to purchase the Secured Loan from the lender for $40.8 million, thereby assuming first-priority secured rights to the underlying collateral for the amount of the Secured Loan, and cancelling our guarantee. The onion products supplier filed for bankruptcy during the fourth quarter of fiscal 2012. During the second quarter of fiscal 2013, we acquired ownership and all rights to the collateral, consisting of agricultural land and a processing facility. During the third quarter of fiscal 2013, we recognized an impairment charge of $10.2 million in our Commercial Foods segment to reduce the carrying amount of these assets to their estimated fair value based upon updated appraisals. During the second quarter of fiscal 2014, we recognized an additional impairment charge of $8.9 million in our Commercial Foods segment to reduce the carrying amount of the plant assets to their estimated fair value based upon expected sales proceeds. In the fourth quarter of fiscal 2014, we sold the land and recognized a gain of $5.1 million in our Commercial Foods segment. Based on our estimate of the value of the processing facility, we expect to recover the remaining carrying value through our sale of this asset.
	Federal income tax credits were generated related to our sweet potato production facility in Delhi, Louisiana. Third parties invested in certain of these income tax credits. We have guaranteed these third parties the face value of these 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 May 25, 2014. We believe the likelihood of the recapture or reduction of the income tax credits is remote, and therefore we have not established a liability in connection with this guarantee.
	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 2014 related to the peanut butter recall is an ongoing investigation by the U.S. Attorney's office in Georgia and the Consumer Protection Branch of the Department of Justice. In fiscal 2011, we received formal requests from the U.S. Attorney's office in Georgia seeking a variety of records and information related to the operations of our peanut butter manufacturing facility in Sylvester, Georgia. These requests relate to the June 2007 execution of a search warrant at our facility following the February 2007 recall. During fiscal 2013 and 2012, we recognized charges of $7.5 million and $17.5 million, respectively, in connection with this matter. We have been and continue to be engaged in ongoing discussions with the U.S. Attorney's office and the Department of Justice in regard to the investigation. We are pursuing a negotiated resolution, which we believe will likely involve a misdemeanor criminal disposition under the Food, Drug & Cosmetics Act. During the fourth quarter of fiscal 2014, we reduced our accrual by $6.7 million. After taking into account liabilities recorded for these matters, we believe the ultimate resolution of this matter should not have a material adverse effect on our financial conditions, results of operations, or liquidity.
	In addition to the investigation noted above, we were previously engaged in litigation against an insurance carrier to recover our settlement expenditures and defense costs associated with the peanut butter recall. During fiscal 2009, we recognized a charge of $24.8 million in connection with the insurance coverage dispute. During the fourth quarter of fiscal 2013, we reached a settlement on the insurance dispute, pursuant to which we were paid $25.0 million, in addition to retaining the defense costs previously reimbursed to us. We recognized the $25.0 million in income as a reduction to selling, general and administrative (SG&A) expenses during fiscal 2013. In the fourth quarter of fiscal 2014, we received an additional reimbursement of settlement and defense costs of $3.5 million related to this matter, which was recognized in income as a reduction to SG&A expenses.
	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., 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 Engineering Group Inc. refiled its action for indemnity. We will continue to defend this action vigorously. Any exposure in this case is expected to be limited to the applicable insurance deductible.
	In April 2010, an accidental explosion occurred at our flour milling facility in Chester, Illinois. Two employees of a subcontractor and one employee of the primary contractor, Westside Salvage ("Westside"), on the site at the time of the accident suffered injuries. Suit was initiated against Westside and the Company for personal injury claims. During the first quarter of fiscal 2013, a jury in Federal Court sitting in East St. Louis, Illinois, returned a verdict against the Company and Westside and in favor of the three employees. The verdict was in the amount of $77.5 million in compensatory damages apportioned between the Company and Westside and $100.0 million in punitive damages against the Company. Post-trial motions were filed by the Company and the trial court reduced the punitive award by approximately $7 million. We filed an appeal with the Seventh Federal Circuit Court of Appeals on the verdict and the damages in the third quarter of fiscal 2013. The appeal was argued in the second quarter of fiscal 2014 and we are awaiting a decision. Any exposure in this case is expected to be limited to the applicable insurance deductible, for which an amount of $3 million was accrued in a prior period.
	Prior to our ownership of Ralcorp, a lawsuit was brought in the U.S. District Court for the Eastern District of Texas by Frito-Lay North America, Inc. against Ralcorp and Medallion Foods, Inc., a subsidiary of Ralcorp, alleging that certain products manufactured by Medallion infringed Frito-Lays' patents and trademarks and misappropriated trade secrets. After a jury trial during the fourth quarter of fiscal 2013, jurors delivered a verdict in favor of Medallion and Ralcorp on all claims. The matter has been resolved and the case concluded.
	We are a party to an agreement with a third party wherein we have rights to the use of certain intellectual property designed to assist the Company in improving the operating efficiency of its manufacturing operations.  In connection with this agreement, the Company is required to make yearly payments of $2.5 million to the third party. Beginning in fiscal 2015, the Company may be required to make additional payments to the third party based upon a contractual formula for manufacturing efficiencies achieved in applicable production facilities. Our best estimate of the required payment for fiscal 2015 is $6.0 million. If additional operating efficiencies are attained in future periods, the amount of the payments due to the third party could increase materially. The obligation to make such payments is contingent upon achievement of such operating efficiencies and accordingly, it is not currently possible to determine the ultimate amount of such payments. This agreement requires such contractual payments to occur each year from fiscal 2015 through March of fiscal 2021.
	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.

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 May 25, 2014, we had economically hedged certain portions of our anticipated consumption of commodity inputs using derivative instruments with expiration dates through December 2015.
	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 May 25, 2014, we had economically hedged certain portions of our foreign currency risk in anticipated transactions using derivative instruments with expiration dates through July 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.
	Derivatives Designated as Cash Flow Hedges
	During 2011, we entered into interest rate swap contracts to hedge the interest rate risk related to our forecasted issuance of long-term debt in April 2014 (based on the anticipated refinancing of the senior long-term debt maturing at that time). We designated these interest rate swaps as cash flow hedges of the forecasted interest payments related to this anticipated debt issuance and recorded the unrealized loss in accumulated other comprehensive loss. In the third quarter of fiscal 2014, we determined that we would not issue long-term debt to refinance the debt maturing in April 2014. Accordingly, we recognized a charge to earnings, within selling, general and administrative expenses, of $54.9 million in fiscal 2014.
	During fiscal 2013, we entered into interest rate swap contracts to hedge a portion of the interest rate risk related to our issuance of long-term debt to partially finance the acquisition of Ralcorp. We settled these contracts during the third quarter of fiscal 2013 resulting in a deferred gain of $4.2 million on senior notes maturing in 2043 and a deferred loss of $2.0 million on senior notes maturing in 2023, both recognized in accumulated other comprehensive loss. These amounts are being amortized as a component of net interest expense over the lives of the related debt instruments. The unamortized amounts of the deferred gain and deferred loss at May 25, 2014 were $3.9 million and $1.8 million, respectively.
	Derivatives Designated as Fair Value Hedges
	During fiscal 2010, we entered into interest rate swap contracts to hedge the fair value of certain of our senior long-term debt instruments maturing in fiscal 2012 and 2014. We designated these interest rate swap contracts as fair value hedges of the debt instruments.
	During fiscal 2011, we terminated these interest rate swap contracts and received proceeds of $31.5 million. The cumulative adjustment to the fair value of the debt instruments being hedged was included in long-term debt and was amortized as a reduction of interest expense over the remaining lives of the debt instruments through fiscal 2014.
	During fiscal 2014, we entered into interest rate swap contracts to hedge the fair value of certain of our senior long-term debt instruments maturing in fiscal 2019 and 2020, effectively converting interest on this debt from fixed rate to floating rate. We designated these interest rate swap contracts as fair value hedges of the debt instruments. The notional amount of the interest rate derivatives outstanding at May 25, 2014 was $500.0 million.
	Changes in fair value of such derivative instruments are immediately recognized in earnings along with changes in the fair value of the items being hedged (based solely on the change in the benchmark interest rate). In fiscal 2014, we recognized a gain of $9.1 million representing the fair value of the interest rate swap contracts and a loss of $6.8 million representing the change in fair value of the related senior long-term debt. Of these offsetting gains and losses, net gains of $2.3 million are classified within selling, general and administrative expenses.
	The entire change in fair value of the derivative instruments was included in our assessment of hedge effectiveness.
	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.
	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.
	Derivative Activity in Our Milling Operations
	We also use derivative instruments within our milling operations, which are part of the Commercial Foods segment. Derivative instruments used to economically hedge commodity inventories and forward purchase and sales contracts within the milling operations are marked-to-market such that realized and unrealized gains and losses are immediately included in operating results. The underlying inventory and forward contracts being hedged are also marked-to-market with changes in market value recognized immediately in operating results.
	For commodity derivative trading activities within our milling operations that are not intended to mitigate commodity input cost risk, derivative instruments are marked-to-market each period with gains and losses included in net sales of the Commercial Foods segment. Net derivative losses from trading activities of $6.3 million, $11.5 million, and $6.4 million were included in the results of operations for the Commercial Foods segment for fiscal years 2014, 2013, and 2012, respectively.
	All derivative instruments are recognized on the Consolidated Balance Sheets at fair value. 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 generally accepted accounting principles, 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 May 25, 2014, $6.2 million, representing an obligation to return cash collateral, was included in other accrued liabilities, and, at May 26, 2013, $10.2 million, representing a right to reclaim cash collateral, was included in prepaid expenses and other current assets in our Consolidated Balance Sheets.
	Derivative assets and liabilities and amounts representing a right to reclaim cash collateral or obligation to return cash collateral were reflected in our Consolidated Balance Sheets as follows:
		May 25, 2014				May 26, 2013
	Prepaid expenses and other current assets	$	81.2			$	78.6
	Other accrued liabilities	22.2				137.9

As of May 25, 2014, our open commodity contracts had a notional value (defined as notional quantity times market value per notional quantity unit) of $1.5 billion and $1.6 billion for purchase and sales contracts, respectively. As of May 26, 2013, our open commodity contracts had a notional value of $1.8 billion and $1.5 billion for purchase and sales contracts, respectively. The notional amount of our foreign currency forward and cross currency swap contracts as of May 25, 2014 and May 26, 2013 was $170.1 million and $359.0 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 May 25, 2014, 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 $68.0 million.

Compensation and Retirement 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. Effective August 1, 2013, our defined benefit pension plan for eligible salaried employees was closed to new hire salaried employees. New hire salaried employees will generally be eligible to participate in our defined contribution plan.
	We recognize the funded status of our plans and other benefits in the Consolidated Balance Sheets. For our plans, we also recognize as a component of accumulated other comprehensive loss, the net of tax results of the actuarial gains or losses within the corridor and prior service costs or credits that arise during the period but are not recognized in net periodic benefit cost. For our other benefits, we also recognize as a component of accumulated other comprehensive income (loss), the net of tax results of the gains or losses and prior service costs or credits that arise during the period but are not recognized in net periodic benefit cost. These amounts will be adjusted out of accumulated other comprehensive income (loss) as they are subsequently recognized as components of net periodic benefit cost.
	During fiscal 2012, we amended certain of our postretirement benefit plans to incorporate design changes. As a result of the plan amendments, we remeasured our postretirement obligation at September 8, 2011. The discount rate used to measure the other postretirement benefits obligation at September 8, 2011 was 4.3% compared to the May 29, 2011 discount rate of 4.9%. All other significant assumptions remained unchanged from the May 29, 2011 measurement date. Calculated gains of $27.6 million as a result of the remeasurement, primarily due to favorable plan amendments, were recognized as a credit to other comprehensive loss. As a result of these plan amendments, our net expense related to these plans was reduced by approximately $5.2 million during fiscal 2012.
	The changes in benefit obligations and plan assets at May 25, 2014 and May 26, 2013 are presented in the following table.

We amortize prior service cost for our pension plans and postretirement plans, as well as amortizable gains and losses for our postretirement plans, in equal annual amounts over the average expected future period of vested service. For plans with no active participants, average life expectancy is used instead of average expected useful service.

Level 1 assets are valued based on quoted prices in active markets for identical securities. The majority of the Level 1 assets listed above include the common stock of both U.S. and international companies, mutual funds, master limited partnership units, and real estate investment trusts, all of which are actively traded and priced in the market. Level 2 assets are valued based on other significant observable inputs including quoted prices for similar securities, yield curves, indices, etc. The Level 2 assets listed above consist primarily of commingled equity investments where values are based on the net asset value of the underlying investments held, individual fixed income securities where values are based on quoted prices of similar securities and observable market data, and commingled fixed income investments where values are based on the net asset value of the underlying investments held. Level 3 assets are those where the fair value is determined based on unobservable inputs. The Level 3 assets listed above consist of alternative investments where active market pricing is not readily available and, as such, we use net asset values as an estimate of fair value as a practical expedient. For real estate funds, the value is based on the net asset value provided by the investment manager who uses market data and independent third party appraisals to determine fair market value. For the multi-strategy hedge funds, the value is based on the net asset values provided by a third party administrator. For private equity and private energy funds, the investment manager provides the valuation using, among other things, comparable transactions, comparable public company data, discounted cash flow analysis, and market conditions.
Level 3 investments are generally considered long-term in nature with varying redemption availability. Certain of our Level 3 investments, with a fair value of approximately $635.4 million as of May 25, 2014, have the ability to impose customary redemption gates which may further restrict or limit the redemption of invested funds therein. As of May 25, 2014, Level 3 investments with a fair value of $2.2 million have imposed such gates.
As of May 25, 2014, we have unfunded commitments for additional investments of $38.6 million in the private equity funds, $27.6 million in the private energy funds, and $80.0 million in real estate funds. We expect unfunded commitments to be funded from plan assets rather than the general assets of the Company.
To develop the expected long-term rate of return on plan assets assumption for the pension plans, we consider the current asset allocation strategy, the historical investment performance, and the expectations for future returns of each asset class.
Our pension plan weighted-average asset allocations and our target asset allocations, by asset category were as follows:
		25-May-14			26-May-13			Target
								Allocation
Equity securities		41	%		47	%		38	%
Debt securities		26	%		23	%		21	%
Real estate funds		6	%		3	%		6	%
Multi-strategy hedge funds		13	%		13	%		15	%
Private equity		2	%		2	%		8	%
Other		12	%		12	%		12	%
Total		100	%		100	%		100	%
The Company’s investment strategy reflects the expectation that equity securities and multi-strategy hedge funds will outperform debt securities over the long term. Assets are invested in a prudent manner to maintain the security of funds while maximizing returns within the Company’s Investment Policy guidelines. The strategy is implemented utilizing indexed and actively managed assets from the categories listed.
The investment goals are to provide a total return that, over the long term, increases the ratio of plan assets to liabilities subject to an acceptable level of risk. This is accomplished through diversification of assets in accordance with the Investment Policy guidelines. Investment risk is mitigated by periodic rebalancing between asset classes as necessitated by changes in market conditions within the Investment Policy guidelines.
Other investments are primarily made up of cash and master limited partnerships.

Multiemployer Pension Plans
The Company contributes to several multiemployer defined benefit pension plans under collective bargaining agreements that cover certain of its union-represented employees. The risks of participating in such plans are different from the risks of single-employer plans, in the following respects:
a.	Assets contributed to a multiemployer plan by one employer may be used to provide benefits to employees of other participating employers.
b.	If a participating employer ceases to contribute to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers.
c.	If the Company ceases to have an obligation to contribute to a multiemployer plan in which it had been a contributing employer, it may be required to pay to the plan an amount based on the underfunded status of the plan and on the history of the Company’s participation in the plan prior to the cessation of its obligation to contribute. The amount that an employer that has ceased to have an obligation to contribute to a multiemployer plan is required to pay to the plan is referred to as a withdrawal liability.
The Company’s participation in multiemployer plans for the fiscal year ended May 25, 2014 is outlined in the table below. For each plan that is individually significant to the Company the following information is provided:
•	The “EIN / PN” column provides the Employer Identification Number and the three-digit plan number assigned to a plan by the Internal Revenue Service.
•	The most recent Pension Protection Act Zone Status available for 2013 and 2012 is for plan years that ended in calendar years 2013 and 2012, respectively. The zone status is based on information provided to the Company by each plan. A plan in the “red” zone has been determined to be in “critical status”, based on criteria established under the Internal Revenue Code (“Code”), and is generally less than 65% funded. A plan in the “yellow” zone has been determined to be in “endangered status”, based on criteria established under the Code, and is generally less than 80% funded. A plan in the “green” zone has been determined to be neither in “critical status” nor in “endangered status”, and is generally at least 80% funded.
•	The “FIP/RP Status Pending/Implemented” column indicates whether a Funding Improvement Plan, as required under the Code to be adopted by plans in the “yellow” zone, or a Rehabilitation Plan, as required under the Code to be adopted by plans in the “red” zone, is pending or has been implemented by the plan as of the end of the plan year that ended in calendar year 2013.
•	Contributions by the Company are the amounts contributed in the Company’s fiscal periods ending in the specified year.
•	The “Surcharge Imposed” column indicates whether the Company contribution rate for its fiscal year that ended on May 25, 2014 included an amount in addition to the contribution rate specified in the applicable collective bargaining agreement, as imposed by a plan in “critical status”, in accordance with the requirements of the Code.
•	The last column lists the expiration dates of the collective bargaining agreements pursuant to which the Company contributes to the plans.
For plans that are not individually significant to ConAgra Foods the total amount of contributions is presented in the aggregate.

The Company will be listed in its plans' Forms 5500 as providing more than 5% of the plan's total contributions for the National Conference of Firemen & Oilers National Pension Fund for the plan year ending in calendar year 2013.
The Company was not listed in the Forms 5500 filed by any of the other plans or for any of the other years as providing more than 5% of the plan’s total contributions. At the date our financial statements were issued, Forms 5500 were not available for plan years ending in calendar year 2013.
In addition to the contributions listed for fiscal 2014 in the table above, we recorded an additional expense of $0.2 million and $14.2 million in fiscal 2014 and 2013, respectively, related to our expected incurrence of certain withdrawal costs.
Certain of our employees are covered under defined contribution plans. The expense related to these plans was $40.2 million, $30.7 million, and $24.2 million in fiscal 2014, 2013, and 2012, respectively.

Fair Value, Assets, Liabilities and Stockholders' Equity Measured on Recurring Basis [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, interest rate swaps, 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 May 25, 2014:
		Level 1		Level 2		Level 3		Total
	Assets:

	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.
	During fiscal 2014, the $20.3 million carrying amount of a potato processing and storage facility (level 3 asset) was written down to its fair value of $3.8 million, resulting in an impairment charge of $16.5 million to selling, general and administrative expenses in the Commercial Foods segment. The fair value measurement used to determine the impairment was based upon the expected sales price.
	During fiscal 2013, the $40.8 million carrying amount of agricultural land and a processing facility (level 3 assets) acquired from an onion products supplier was written-down to its fair value of $30.6 million, resulting in an impairment charge of $10.2 million. The fair value of the measurement used to determine the impairment was based upon updated appraisals. In 2014, the processing facility, with a carrying value of $19.7 million was written-down to its fair value of $10.8 million resulting in an impairment charge of $8.9 million. The fair value of the measurement used to determine the impairment was based upon expected sales price. The impairment charges are included in selling, general and administrative expenses in the Commercial Foods segment (see Note 16).
	During fiscal 2014, the $68.9 million carrying amount of assets held for sale (level 3 assets, which were disposed of in the fourth quarter of fiscal 2014) of the discontinued operations of Medallion Foods within the Private Brands segment were written-down to their fair value of $43.5 million. The resulting impairment charge of $25.4 million is included in discontinued operations. The fair value measurement used to determine the impairment was based upon the expected business sales price (see Note 6).
	During fiscal 2014, a goodwill impairment charge of $602.2 million was recognized within the Private Brands segment. See Note 8 for a discussion of the methodology employed to measure this impairment.
	During fiscal 2014, impairments of certain indefinite-lived brands were recognized in the amounts of $72.5 million and $3.2 million in the Consumer Foods and Private Brands segments, respectively. The fair values of these brands were estimated using the “relief from royalty” method.
	During fiscal 2014, an impairment charge of $3.2 million was recognized in corporate expenses, as the company determined an amortizing technology license was no longer expected to produce future economic benefit.  Accordingly, the carrying value of the asset was entirely written off.
	The carrying amount of long-term debt (including current installments) was $8.9 billion as of May 25, 2014 and $9.4 billion as of May 26, 2013. Based on current market rates, the fair value of this debt (level 2 liabilities) at May 25, 2014 and May 26, 2013, was estimated at $9.5 billion and $10.2 billion, respectively. Included in the May 25, 2014 long-term debt carrying amount, and excluded from the above fair value table, is $0.5 billion of hedged debt that, along with the related hedge instruments, is adjusted for changes in fair value based solely on the change in the related benchmark interest rate (see Note 17).

	BUSINESS SEGMENTS AND RELATED INFORMATION
	As a result of the Ralcorp acquisition, we implemented organizational changes during the second quarter of fiscal 2014 that resulted in new reporting segments. We began reporting our operations in three reporting segments: Consumer Foods, Commercial Foods, and Private Brands. We believe this recent operating structure will enhance our focus on profitability, coordinated business execution, and resource allocation across our business. Prior periods have been reclassified to conform to the revised segment presentation. Prior to this change in organizational structure, we had four operating and reportable segments.
	The Consumer Foods reporting segment includes branded food sold in various retail channels primarily in North America. Our food products are found in a variety of categories (meals, entrees, condiments, sides, snacks, and desserts) throughout grocery and convenience stores across frozen, refrigerated, and shelf-stable temperature classes. The Consumer Foods reporting segment no longer includes results for store brands (store brands are now part of the recently created Private Brands segment) or foodservice results (the foodservice business is now part of the Commercial Foods segment). The Consumer Foods reporting segment now includes additional international sales which were previously part of the Ralcorp Food Group segment.
	The Commercial Foods reporting segment includes commercially branded and private branded food and ingredients, which are sold primarily to commercial, foodservice, food manufacturing, and industrial customers. The segment's primary food items include: frozen potato and sweet potato items and a variety of vegetable, spice and frozen bakery goods which are sold under brands such as Lamb Weston® and Spicetec Flavors & Seasonings®. The Commercial Foods reporting segment now includes foodservice results which were previously part of the Consumer Foods segment, as well as frozen bakery foodservice results, which were previously part of the Ralcorp Frozen Bakery Products segment. Our milling business was included in the Commercial Foods segment for the periods covered by this report but was contributed to Ardent Mills shortly after the end of fiscal 2014.
	The Private Brands reporting segment includes private branded and customized food items sold in various retail channels, primarily in North America. Our Private Brands are sold in a variety of categories in grocery and convenience stores including: hot and ready-to-eat cereal; snacks; condiments; bars and coordinated categories; pasta; and retail bakery goods. The recently created Private Brands reporting segment includes a significant portion of results from the former Ralcorp businesses and the store brands results which were previously part of the Consumer Foods segment.
	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.

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 (except those related to our milling operations, see Note 17 to our consolidated financial statements) 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.
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:
	2014			2013			2012
Net derivative gains (losses) incurred	$	25.7		$	74.8		$	(66.8	)
Less: Net derivative gains (losses) allocated to reporting segments	(10.3		)	25			24.4
Net derivative gains (losses) recognized in general corporate expenses	$	36		$	49.8		$	(91.2	)
Net derivative gains (losses) allocated to Consumer Foods	$	(5.9	)	$	26.7		$	25.3
Net derivative gains (losses) allocated to Commercial Foods	6.4			(2.7		)	(0.5		)
Net derivative gains (losses) allocated to Private Brands	(10.8		)	1			(0.4		)
Net derivative gains (losses) included in segment operating profit	$	(10.3	)	$	25		$	24.4
As of May 25, 2014, 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 $26.9 million. This amount reflected net gains of $25.7 million incurred during the fiscal year ended May 25, 2014, as well as net gains of $1.2 million incurred prior to fiscal 2014. Based on our forecasts of the timing of recognition of the underlying hedged items, we expect to reclassify to segment operating results gains of $26.5 million and $0.4 million to segment operating results in fiscal 2015 and 2016 and thereafter, respectively.
Other Information
At May 25, 2014, ConAgra Foods and its subsidiaries had approximately 32,800 employees, primarily in the United States. Approximately 41% of our employees are parties to collective bargaining agreements. Of the employees subject to collective bargaining agreements, approximately 16% are parties to collective bargaining agreements scheduled to expire during fiscal 2015.
Our operations are principally in the United States. With respect to operations outside of the United States, no single foreign country or geographic region was significant with respect to consolidated operations for fiscal 2014, 2013, and 2012. Foreign net sales, including sales by domestic segments to customers located outside of the United States, were approximately $2.2 billion, $1.9 billion, and $1.6 billion in fiscal 2014, 2013, and 2012, respectively. Our long-lived assets located outside of the United States are not significant.
Our largest customer, Wal-Mart Stores, Inc. and its affiliates, accounted for approximately 17% of consolidated net sales for each of fiscal 2014, 2013, and 2012, significantly impacting the Consumer Foods and Private Brands segments.
Wal-Mart Stores, Inc. and its affiliates accounted for approximately 14% and 15% of consolidated net receivables as of May 25, 2014 and May 26, 2013, respectively, significantly impacting the Consumer Foods and Private Brands segments.

SUMMARY_OF_SIGNIFICANT_ACCOUNT1

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	25-May-14
Accounting Policies [Abstract]	'
Fiscal Year	'
	Fiscal Year — The fiscal year of ConAgra Foods, Inc. (“ConAgra Foods”, “Company”, “we”, “us”, or “our”) ends the last Sunday in May. The fiscal years for the consolidated financial statements presented consist of 52-week periods for fiscal years 2014, 2013, and 2012.
Basis of Consolidation	'
	Basis of Consolidation — The 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 consolidated financial statements from the date such determination is made. All significant intercompany investments, accounts, and transactions have been eliminated.
Investments in Unconsolidated Affiliates	'
	Investments in Unconsolidated Affiliates — The investments in, and the operating results of, 50%-or-less-owned entities not required to be consolidated are included in the consolidated financial statements on the basis of the equity method of accounting or the cost method of accounting, depending on specific facts and circumstances.
	We review our investments in unconsolidated affiliates for impairment whenever events or changes in business circumstances indicate that the carrying amount of the investments may not be fully recoverable. Evidence of a loss in value that is other than temporary includes, but is not limited to, the absence of an ability to recover the carrying amount of the investment, the inability of the investee to sustain an earnings capacity which would justify the carrying amount of the investment, or, where applicable, estimated sales proceeds which are insufficient to recover the carrying amount of the investment. Management’s assessment as to whether any decline in value is other than temporary is based on our ability and intent to hold the investment and whether evidence indicating the carrying value of the investment is recoverable within a reasonable period of time outweighs evidence to the contrary. Management generally considers our investments in equity method investees to be strategic long-term investments. Therefore, management completes its assessments with a long-term viewpoint. If the fair value of the investment is determined to be less than the carrying value and the decline in value is considered to be other than temporary, an appropriate write-down is recorded based on the excess of the carrying value over the best estimate of fair value of the investment.
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.
Inventories	'
	Inventories — We principally use the lower of cost (determined using the first-in, first-out method) or market for valuing inventories other than merchandisable agricultural commodities. Grain and flour inventories are principally stated at market value.
Property, Plant and Equipment	'
	Property, Plant and Equipment — Property, plant and equipment are carried at cost. Depreciation has been calculated using the straight-line method over the estimated useful lives of the respective classes of assets as follows:
	Land improvements		1 - 40 years
	Buildings		15 - 40 years
	Machinery and equipment		3 - 20 years
	Furniture, fixtures, office equipment and other		5 - 15 years
	We review property, plant and equipment for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Recoverability of an asset considered “held-and-used” is determined by comparing the carrying amount of the asset to the undiscounted net cash flows expected to be generated from the use of the asset. If the carrying amount is greater than the undiscounted net cash flows expected to be generated by the asset, the asset’s carrying amount is reduced to its estimated fair value. An asset considered “held-for-sale” is reported at the lower of the asset’s carrying amount or fair value.
Goodwill and Other Identifiable Intangible Assets	'
	Goodwill and Other Identifiable Intangible Assets — Goodwill and other identifiable intangible assets with indefinite lives (e.g., brands or trademarks) are not amortized and are tested annually for impairment of value and whenever events or changes in circumstances indicate the carrying amount of the asset may be impaired. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include deterioration in general economic conditions, adverse changes in the markets in which an entity operates, increases in input costs that have negative effects on earnings and cash flows, or a trend of negative or declining cash flows over multiple periods, among others. The fair value that could be realized in an actual transaction may differ from that used to evaluate the impairment of goodwill and other intangible assets.
	In testing goodwill for impairment, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (more than 50%) that the estimated fair value of a reporting unit is less than its carrying amount. If we elect to perform a qualitative assessment and determine that an impairment is more likely than not, we are then required to perform a quantitative impairment test, otherwise no further analysis is required. We also may elect not to perform the qualitative assessment and, instead, proceed directly to the quantitative impairment test.
	Under the goodwill qualitative assessment, various events and circumstances that would affect the estimated fair value of a reporting unit are identified (similar to impairment indicators above). Furthermore, management considers the results of the most recent two-step quantitative impairment test completed for a reporting unit and compares the weighted average cost of capital between the current and prior years for each reporting unit.
	Under the goodwill two-step quantitative impairment test, the evaluation of impairment involves comparing the current fair value of each reporting unit to its carrying value, including goodwill. The first step of the test compares the carrying value of a reporting unit, including goodwill, with its fair value. We estimate the fair value using level 3 inputs as defined by the fair value hierarchy. Refer to Note 19 for the definition of the levels in the fair value hierarchy. The inputs used to calculate the fair value include a number of subjective factors, such as estimates of future cash flows, estimates of our future cost structure, discount rates for our estimated cash flows, required level of working capital, assumed terminal value, and time horizon of cash flow forecasts. If the carrying value of a reporting unit exceeds its fair value, we complete the second step of the test to determine the amount of goodwill impairment loss, if any, to be recognized. In the second step, we estimate an implied fair value of the reporting unit’s goodwill by allocating the fair value of the reporting unit to all of the assets and liabilities other than goodwill (including any unrecognized intangible assets). The impairment loss is equal to the excess of the carrying value of the goodwill over the implied fair value of that goodwill.
	We implemented organizational changes during the second quarter of fiscal 2014 that resulted in new reporting segments. As a result, we reassigned goodwill to the new reporting units using a relative fair value allocation approach and performed an analysis of the potential impairment of goodwill.
	In the fourth quarter of fiscal 2014, in conjunction with our annual review for impairment, we performed a qualitative analysis of goodwill for each of the reporting units in our segments. As sales and profits for Private Brands continued to be softer than we expected through fiscal 2014, we performed a quantitative analysis of goodwill of our Private Brands segment. Estimating the fair value of individual reporting units requires us to make assumptions and estimates regarding our future plans, industry and economic conditions. Refer to Note 8 for the details of the impairment charges in fiscal 2014.
	In assessing other intangible assets not subject to amortization for impairment, we have the option to perform a qualitative assessment to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of such an intangible asset is less than its carrying amount. If we determine that it is not more likely than not that the fair value of such an intangible asset is less than its carrying amount, then we are not required to perform any additional tests for assessing intangible assets for impairment. However, if we conclude otherwise or elect not to perform the qualitative assessment, then we are required to perform a quantitative impairment test that involves a comparison of the estimated fair value of the intangible asset with its carrying value. If the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.
	In fiscal 2014, we elected to perform a quantitative impairment test for other intangible assets not subject to amortization. The estimates of fair value of intangible assets not subject to amortization are determined using a “relief from royalty” methodology, which is used in estimating the fair value of our brands/trademarks. Discount rate assumptions are based on an assessment of the risk inherent in the projected future cash flows generated by the respective intangible assets. Also subject to judgment are assumptions about royalty rates. Refer to Note 8 for the details of the impairment charges in fiscal 2014.
	Identifiable intangible assets with definite lives (e.g., licensing arrangements with contractual lives or customer relationships) are amortized over their estimated useful lives and tested for impairment whenever events or changes in circumstances indicate the carrying amount of the asset may be impaired. Identifiable intangible assets with definite lives are evaluated for impairment using a process similar to that used in evaluating elements of property, plant and equipment. If impaired, the asset is written down to its fair value.
Fair Values of Financial Instruments	'
	Fair Values of Financial Instruments — Unless otherwise specified, we believe the carrying value of financial instruments approximates their fair value.
Environmental Liabilities	'
	Environmental Liabilities — Environmental liabilities are accrued when it is probable that obligations have been incurred and the associated amounts can be reasonably estimated. We use third-party specialists to assist management in appropriately measuring the obligations associated with environmental liabilities. Such liabilities are adjusted as new information develops or circumstances change. We do not discount our environmental liabilities as the timing of the anticipated cash payments is not fixed or readily determinable. Management’s estimate of our potential liability is independent of any potential recovery of insurance proceeds or indemnification arrangements. We do not reduce our environmental liabilities for potential insurance recoveries.
Employment-Related Benefits	'
	Employment-Related Benefits — Employment-related benefits associated with pensions, postretirement health care benefits, and workers’ compensation are expensed as such obligations are incurred. The recognition of expense is impacted by estimates made by management, such as discount rates used to value these liabilities, future health care costs, and employee accidents incurred but not yet reported. We use third-party specialists to assist management in appropriately measuring the obligations associated with employment-related benefits.
	We recognize changes in the fair value of pension plan assets and net actuarial gains or losses in excess of 10% of the greater of the market-related value of plan assets or the plan’s projected benefit obligation (“the corridor”) in current period expense annually as of our measurement date, which is our fiscal year-end, or when measurement is required otherwise under generally accepted accounting principles.
Revenue Recognition	'
	Revenue Recognition — Revenue is recognized when title and risk of loss are transferred to customers upon delivery based on terms of sale and collectability is reasonably assured. Revenue is recognized as the net amount to be received after deducting estimated amounts for discounts, trade allowances, and returns of damaged and out-of-date products. Changes in the market value of inventories of merchandisable agricultural commodities, the fair values of forward cash purchase and sales contracts, and exchange-traded futures and options contracts are recognized in earnings immediately.
Shipping and Handling	'
	Shipping and Handling — Amounts billed to customers related to shipping and handling are included in net sales. Shipping and handling costs are included in cost of goods sold.
Marketing Costs	'
	Marketing Costs — We promote our products with advertising, consumer incentives, and trade promotions. Such programs include, but are not limited to, discounts, coupons, rebates, and volume-based incentives. Advertising costs are expensed as incurred. Consumer incentives and trade promotion activities are recorded as a reduction of revenue or as a component of cost of goods sold based on amounts estimated as being due to customers and consumers at the end of the period, based principally on historical utilization and redemption rates. Advertising and promotion expenses totaled $417.4 million, $466.3 million, and $362.3 million in fiscal 2014, 2013, and 2012, respectively, and are included in selling, general and administrative expenses.
Research and Development	'
	Research and Development — We incurred expenses of $103.5 million, $93.1 million, and $86.0 million for research and development activities in fiscal 2014, 2013, and 2012, respectively.
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 postretirement 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. We reclassified $6.0 million of foreign currency translation losses to net income in fiscal 2012 due to our acquisition of a majority interest in Agro Tech Foods Limited ("ATFL") in India and the related remeasurement of our previously held noncontrolling equity interest in ATFL to fair value (see Note 2).

Foreign Currency Transaction Gains and Losses	'
	Foreign Currency Transaction Gains and Losses — We recognized net foreign currency transaction losses from continuing operations of $13.5 million, $0.1 million, and $3.9 million in fiscal 2014, 2013, and 2012, respectively, in selling, general and administrative expenses.
Business Combinations	'
	Business Combinations — We use the acquisition method in accounting for acquired businesses. Under the acquisition method, our financial statements reflect the operations of an acquired business starting from the completion of the acquisition. The assets acquired and liabilities assumed are recorded at their respective estimated fair values at the date of the acquisition. Any excess of the purchase price over the estimated fair values of the identifiable net assets acquired is recorded as goodwill.
Reclassifications	'
	Reclassifications — 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 generally accepted accounting principles requires management to make estimates and assumptions. These estimates and assumptions affect reported amounts of assets, liabilities, revenues, and expenses as reflected in the consolidated financial statements. Actual results could differ from these estimates.
