Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIES We are a party to various environmental proceedings and litigation, primarily related to our acquisition in fiscal 1991 of Beatrice Company ("Beatrice"). As a result of the acquisition of Beatrice and the significant pre-acquisition contingencies of the Beatrice businesses and its former subsidiaries, our condensed consolidated post-acquisition financial statements reflect liabilities associated with the estimated resolution of these contingencies. Such liabilities include various litigation and environmental proceedings related to businesses divested by Beatrice prior to our acquisition of Beatrice. The Beatrice-related litigation proceedings include suits against a number of lead paint and pigment manufacturers, including ConAgra Grocery Products Company, LLC, a wholly owned subsidiary of the Company ("ConAgra Grocery Products") as alleged successor to W. P. Fuller & Co., a lead paint and pigment manufacturer owned and operated by a predecessor to Beatrice from 1962 until 1967. These lawsuits generally seek damages for personal injury, property damage, economic loss, and governmental expenditures allegedly caused by the use of lead-based paint and/or injunctive relief for inspection and abatement. 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. ConAgra Grocery Products has denied liability in both suits, both on the merits of the claims and on the basis that we do not believe it to be the successor to any liability attributable to W. P. Fuller & Co. The California suit is discussed in the following paragraph. The Illinois suit seeks class-wide relief for reimbursement of costs associated with the testing of lead levels in blood. We do not believe it is probable that we have incurred any liability with respect to the Illinois case, nor is it possible to estimate any potential exposure. In California, a number of cities and counties joined in a consolidated action seeking abatement of an alleged public nuisance in the form of lead-based paint potentially present on the interior of residences, regardless of its condition. On September 23, 2013, a trial of the California case concluded in the Superior Court of California for the County of Santa Clara, and on January 27, 2014, the court entered a judgment (the "Judgment") against ConAgra Grocery Products and two other defendants ordering the creation of a California abatement fund in the amount of $1.15 billion. Liability is joint and several. The Company appealed the Judgment, and on November 14, 2017 the California Court of Appeal for the Sixth Appellate District reversed in part, holding that the defendants were not liable to pay for abatement of homes built after 1950, but affirmed the Judgment as to homes built before 1951 and remanded to the trial court with directions to recalculate the amount of the abatement fund estimated to be necessary to cover the cost of remediating pre-1951 homes, and to hold an evidentiary hearing regarding appointment of a suitable receiver. ConAgra Grocery Products and the other defendants petitioned the California Supreme Court for review of the decision, which we believe to be an unprecedented expansion of current California law. On February 14, 2018, the California Supreme Court denied the petition and declined to review the merits of the case, and the case was remanded to the trial court for further proceedings. ConAgra Grocery Products and the other defendants have indicated that they will seek further review of certain issues from the United States Supreme Court, although further appeal is discretionary and may not be granted. Further proceedings in the trial court may not be stayed pending the outcome of any further appeal. In light of the decision rendered by the California Appellate Court on November 14, 2017, and the California Supreme Court's decision on February 14, 2018 not to review the Appellate Court's decision, we have concluded that, although the liability has likely become probable as contemplated by Accounting Standards Codification Topic 450, the amount or range of any such liability is not reasonably estimable in light of the many remaining uncertainties. These uncertainties include the following: (i) the trial court has not yet recalculated its estimate of the amount needed to remediate pre-1951 homes in the plaintiff jurisdictions or entered a new judgment to replace the one vacated by the California Appellate Court; (ii) although liability is joint and several, it is unknown what amount each defendant may be required to pay or how allocation among the defendants (and other potentially responsible parties such as property owners who may have violated the applicable housing codes) will be determined; (iii) according to the trial court’s original order, participation in the abatement program by eligible homeowners is voluntary and it is unknown what percentage of eligible homeowners will choose to participate or how such claims will be administered; (iv) the trial court's original order required that any amounts paid by the defendants into the fund that were not spent within four years would be returned to the defendants, and it is unknown whether this feature of the fund will be retained or, if it is retained, how much will be spent during that time period; and (v) defendants will have a new right to appeal any new judgment entered by the trial court upon remand, although it is unknown whether the court would stay execution of any new judgment while a subsequent appeal is pending. If ultimately necessary, the Company will look to its insurance policies for coverage; its carriers are on notice. However, the extent of insurance coverage is uncertain. The Company cannot assure that the final resolution of these matters will not have a material adverse effect on its financial condition, results of operations, or liquidity. The current environmental proceedings associated with Beatrice include litigation and administrative proceedings involving Beatrice's possible status as a potentially responsible party at approximately 40 Superfund, proposed Superfund, or state-equivalent sites (the "Beatrice sites"). These sites involve locations previously owned or operated by predecessors of Beatrice that used or produced petroleum, pesticides, fertilizers, dyes, inks, solvents, PCBs, acids, lead, sulfur, tannery wastes, and/or other contaminants. In the past five years, Beatrice has paid or is in the process of paying its liability share at 31 of these sites. Reserves for these Beatrice environmental proceedings have been established based on our best estimate of the undiscounted remediation liabilities, which estimates include evaluation of investigatory studies, extent of required clean-up, the known volumetric contribution of Beatrice and other potentially responsible parties, and its experience in remediating sites. The accrual for Beatrice-related environmental matters totaled $52.2 million as of February 25, 2018, a majority of which relates to the Superfund and state-equivalent sites referenced above. During the third quarter of fiscal 2017, a final Remedial Investigation/Feasibility Study was submitted for the Southwest Properties portion of the Wells G&H Superfund site, which is one of the Beatrice sites. The U.S. Environmental Protection Agency (the "EPA") issued a Record of Decision (the "ROD") for the Southwest Properties portion of the site on September 29, 2017, and will subsequently enter into negotiations with potentially responsible parties to determine final responsibility for implementing the ROD. In June 2009, an accidental explosion occurred at our manufacturing facility in Garner, North Carolina. This facility was the primary production facility for our Slim Jim^® branded meat snacks. In June 2009, the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives announced its determination that the explosion was the result of an accidental natural gas release and not a deliberate act. During the fourth quarter of fiscal 2011, we settled our property and business interruption claims related to the Garner accident with our insurance providers. During the fourth quarter of fiscal 2011, Jacobs Engineering Group Inc. ("Jacobs"), our engineer and project manager at the site, filed a declaratory judgment action against us seeking indemnity for personal injury claims brought against it as a result of the accident. During the first quarter of fiscal 2012, our motion for summary judgment was granted and the suit was dismissed without prejudice on the basis that the suit was filed prematurely. In the third quarter of fiscal 2014, Jacobs refiled its action seeking indemnity. On March 25, 2016, a Douglas County jury in Nebraska rendered a verdict in favor of Jacobs and against us in the amount of $108.9 million plus post-judgment interest. We filed our Notice of Appeal in September 2016, and the case is awaiting decision by the Nebraska Supreme Court. The appeal will be decided directly by the Nebraska Supreme Court. Although our insurance carriers have provided customary notices of reservation of their rights under the policies of insurance, we expect any ultimate exposure in this case to be limited to the applicable insurance deductible. We are party to a number of putative class action lawsuits challenging various product claims made in the Company's product labeling. These matters include Briseno v. ConAgra Foods, Inc., in which it is alleged that the labeling for Wesson^® oils as 100% natural is false and misleading because the oils contain genetically modified plants and organisms. In February 2015, the U.S. District Court for the Central District of California granted class certification to permit plaintiffs to pursue state law claims. The Company appealed to the United States Court of Appeals for the Ninth Circuit, which affirmed class certification in January 2017. The United States Supreme Court declined to review the decision and the case has been remanded to the trial court for further proceedings. While we cannot predict with certainty the results of this or any other legal proceeding, we do not expect this matter to have a material adverse effect on our financial condition, results of operations, or business. We are party to a number of matters challenging the Company's wage and hour practices. These matters include a number of putative class actions consolidated under the caption Negrete v. ConAgra Foods, Inc., et al, pending in the U.S. District Court for the Central District of California, in which the plaintiffs allege a pattern of violations of California and/or federal law at several current and former Company manufacturing facilities across the State of California. While we cannot predict with certainty the results of this or any other legal proceeding, we do not expect this matter to have a material adverse effect on our financial condition, results of operations, or business. In certain limited situations, we guarantee obligations of the Lamb Weston business pursuant to guarantee arrangements that existed prior to the Spinoff and remained in place following completion of the Spinoff until such guarantee obligations are substituted for guarantees issued by Lamb Weston. Such guarantee arrangements are described below. Pursuant to the Separation and Distribution Agreement, dated as of November 8, 2016 (the "Separation Agreement"), between us and Lamb Weston, these guarantee arrangements are deemed liabilities of Lamb Weston that were transferred to Lamb Weston as part of the Spinoff. Accordingly, in the event that we are required to make any payments as a result of these guarantee arrangements, Lamb Weston is obligated to indemnify us for any such liability, reduced by any insurance proceeds received by us, in accordance with the terms of the indemnification provisions under the Separation Agreement. Lamb Weston is a party to a warehouse services agreement with a third-party warehouse provider through July 2035. Under this agreement, Lamb Weston is required to make payments for warehouse services based on the quantity of goods stored and other service factors. We have guaranteed the warehouse provider that we will make the payments required under the agreement in the event that Lamb Weston fails to perform. Minimum payments of $1.5 million per month are required under this agreement. It is not possible to determine the maximum amount of the payment obligations under this agreement. Upon completion of the Spinoff, we recognized a liability for the estimated fair value of this guarantee. As of February 25, 2018, the amount of this guarantee, recorded in other noncurrent liabilities, was $28.5 million. Lamb Weston is a party to an agricultural sublease agreement with a third party for certain farmland through 2020 (subject, at Lamb Weston's option, to extension for two additional five-year periods). Under the terms of the sublease agreement, Lamb Weston is required to make certain rental payments to the sublessor. We have guaranteed the sublessor Lamb Weston's performance and the payment of all amounts (including indemnification obligations) owed by Lamb Weston under the sublease agreement, up to a maximum of $75.0 million. We believe the farmland associated with this sublease agreement is readily marketable for lease to other area farming operators. As such, we believe that any financial exposure to the company, in the event that we were required to perform under the guaranty, would be largely mitigated. We lease or leased certain office buildings from entities that we have determined to be variable interest entities. The lease agreements with these entities include fixed-price purchase options for the assets being leased. The lease agreements also contain contingent put options (the "lease put options") that allow or allowed the lessors to require us to purchase the buildings at the greater of original construction cost, or fair market value, without a lease agreement in place (the "put price") in certain limited circumstances. As a result of substantial impairment charges related to our divested Private Brands operations, these lease put options became exercisable. During the third quarter of fiscal 2018, we purchased two buildings that were subject to lease put options and recognized net losses totaling $48.2 million for the early exit of unfavorable lease contracts. As of February 25, 2018, there was one remaining leased building subject to a lease put option for which the put option price exceeded the estimated fair value by $8.2 million, of which we had accrued $1.1 million. We are amortizing the difference between the put price and the estimated fair value (without a lease agreement in place) of the property over the remaining lease term within selling, general and administrative expenses. This lease is accounted for as an operating lease, and accordingly, there are no material assets and liabilities, other than the accrued portion of the put price, associated with this entity included in the Condensed Consolidated Balance Sheets. We have determined that we do not have the power to direct the activities that most significantly impact the economic performance of this entity. In making this determination, we have considered, among other items, the terms of the lease agreement, the expected remaining useful life of the asset leased, and the capital structure of the lessor entity. After taking into account liabilities recognized for all of the foregoing matters, management believes the ultimate resolution of such matters should not have a material adverse effect on our financial condition, results of operations, or liquidity. It is reasonably possible that a change of the estimates of any of the foregoing matters may occur in the future and, as noted, the lead paint matter, for which the Company cannot reasonably estimate a liability, could result in a material final judgment. Costs of legal services associated with the foregoing matters are recognized in earnings as services are provided.

We are a party to various environmental proceedings and litigation, primarily related to our acquisition in fiscal 1991 of Beatrice Company ("Beatrice"). As a result of the acquisition of Beatrice and the significant pre-acquisition contingencies of the Beatrice businesses and its former subsidiaries, our condensed consolidated post-acquisition financial statements reflect liabilities associated with the estimated resolution of these contingencies.
