Legal Proceedings [Abstract]
Commitments and Contingencies	Legal Proceedings Antitrust claims In late 2008 and early 2009, approximately 22 class action lawsuits were filed in various federal courts against Michael Foods, Inc. (“MFI”), a wholly owned subsidiary of the Company, and approximately 20 other defendants (producers of shell eggs and egg products, and egg industry organizations), alleging violations of federal and state antitrust laws in connection with the production and sale of shell eggs and egg products, and seeking unspecified damages. All cases were transferred to the Eastern District of Pennsylvania for coordinated and/or consolidated pretrial proceedings. The case involved three plaintiff groups: (i) a nationwide class of direct purchasers of shell eggs (“direct purchaser class”); (ii) individual companies (primarily large grocery chains and food companies that purchase considerable quantities of eggs) that opted out of various settlements and filed their own complaints related to their purchases of shell eggs and egg products (“opt-out plaintiffs”); and (iii) indirect purchasers of shell eggs (“indirect purchaser plaintiffs”). Resolution of claims: To date, MFI has resolved the following claims, including all class claims: (i) in December 2016, MFI settled all claims asserted against it by the direct purchaser class for a payment of $75.0, which was approved by the district court in December 2017; (ii) MFI settled all claims asserted against it by opt-out plaintiffs related to shell egg purchases on confidential terms in January 2017; and (iii) in June 2018, MFI settled all claims asserted against it by indirect purchaser plaintiffs on confidential terms. MFI has at all times denied liability in this matter, and no settlement contains any admission of liability by MFI. Remaining portion of the case: MFI remains a defendant only with respect to claims that seek damages based on purchases of egg products by six opt-out plaintiffs. The district court had granted summary judgment precluding any claims for egg products purchases by such opt-out plaintiffs, but the Third Circuit Court of Appeals reversed and remanded these claims for further pre-trial proceedings. Defendants have filed a second motion for summary judgment seeking dismissal of the claims, and that motion is currently pending. Although the likelihood of a material adverse outcome in the egg antitrust litigation has been significantly reduced as a result of the MFI settlements described above, the remaining portion of the case could still result in a material adverse outcome. No expense was recorded related to these matters in the three months ended December 31, 2018 or 2017. At December 31, 2018 and September 30, 2018, the Company had $6.0 accrued for this matter, which was included in “Other current liabilities” on the Condensed Consolidated Balance Sheets. The Company records reserves for litigation losses in accordance with ASC Topic 450, “Contingencies.” Under ASC Topic 450, a loss contingency is recorded if a loss is probable and can be reasonably estimated. The Company records probable loss contingencies based on the best estimate of the loss. If a range of loss can be reasonably estimated, but no single amount within the range appears to be a better estimate than any other amount within the range, the minimum amount in the range is accrued. These estimates are often initially developed earlier than when the ultimate loss is known, and the estimates are adjusted if additional information becomes known. Although the Company believes its accruals for this matter are appropriate, the final amounts required to resolve such matter could differ materially from recorded estimates and the Company’s financial position, results of operations and cash flows could be materially affected. Under current law, any settlement paid, including the settlements with the direct purchaser plaintiffs, the opt-out plaintiffs and the indirect purchaser plaintiffs, is deductible for federal income tax purposes. Bob Evans Appraisal Proceedings Prior to completion of the Company’s acquisition of Bob Evans on January 12, 2018, Bob Evans received demands from certain stockholders demanding appraisal of their shares of Bob Evans common stock. After the completion of the acquisition, several such former stockholders filed petitions in the Delaware Court of Chancery (Arbitrage Fund v. Bob Evans Farms, Inc. filed on January 23, 2018; Blue Mountain Credit Alternatives Master Fund L.P., et al. v. Bob Evans Farms, Inc. filed on April 30, 2018; and 2017 Clarendon LLC, et al. v. Bob Evans Farms, Inc. filed on April 30, 2018) seeking appraisal of their shares of Bob Evans common stock pursuant to Section 262 of the Delaware General Corporation Law (“Section 262”). The lawsuits seek appraisal for such shares, plus statutory interest, as well as the costs of the proceedings and such other relief as appropriate. Under Section 262, persons who were stockholders at the time of the closing are entitled to have their shares appraised by the Delaware Court of Chancery and receive payment of the “fair value” of such shares (plus statutory interest) as determined by the Delaware Court of Chancery. In May 2018, the court consolidated the lawsuits into one action. In December 2018, the Company settled with one petitioner, Arbitrage Fund, and Arbitrage Fund was dismissed with prejudice from the consolidated action. In addition, in December 2018, the Company pre-paid the $77.00 per share merger consideration to the Blue Mountain and 2017 Clarendon petitioners, effectively stopping the continued accrual of statutory interest on that amount. The Company made total payments of $257.6 related to these matters in December 2018. However, the consolidated action remains active with respect to the determination of the fair value of the shares formerly held by the two remaining petitioners. Approximately 2.5 shares of Bob Evans common stock are before the court for appraisal in the consolidated action. As of completion of the acquisition, former Bob Evans stockholders can no longer submit new demands for appraisal. All other former stockholders have been paid for their shares. The Company intends to vigorously defend the consolidated action. At September 30, 2018, former holders of 3.3 shares of Bob Evans common stock had not withdrawn their appraisal demands and had not been paid for their shares of Bob Evans common stock. Related to these shares, the Company accrued $267.0 at September 30, 2018, which was the number of shares of Bob Evans common stock for which former Bob Evans stockholders demanded appraisal and had not withdrawn their demands multiplied by the $77.00 per share merger consideration, plus statutory interest. At December 31, 2018, former holders of 2.5 shares of Bob Evans common stock had not withdrawn their appraisal demands. At December 31, 2018, the Company had a remaining accrual of $13.7, which represents the accrued statutory interest related to the 2.5 shares for which the $77.00 per share merger consideration was paid. Additional payments related to these 2.5 shares could be made in the future. The liabilities were reported in “Other current liabilities” and “Other liabilities” on the Condensed Consolidated Balance Sheets at December 31, 2018 and September 30, 2018, respectively. While the Company believes its accrual for these matters is appropriate, the final amounts required to resolve such matters could differ materially and the Company’s financial position, results of operations and cash flows could be materially affected. Accordingly, the Company cannot predict what impact, if any, these matters and any results from such matters could have on the Company’s future financial position, results of operations or cash flows. Other The Company is subject to various other legal proceedings and actions arising in the normal course of business. In the opinion of management, based upon the information presently known, the ultimate liability, if any, arising from such pending legal proceedings, as well as from asserted legal claims and known potential legal claims which are likely to be asserted, taking into account established accruals for estimated liabilities (if any), are not expected to be material individually or in the aggregate to the financial position, results of operations or cash flows of the Company. In addition, although it is difficult to estimate the potential financial impact of actions regarding expenditures for compliance with regulatory matters, in the opinion of management, based upon the information currently available, the ultimate liability arising from such compliance matters is not expected to be material to the financial position, results of operations or cash flows of the Company. Leases Historically, Bob Evans guaranteed certain payment and performance obligations associated with the leases for 143 properties (the "Guarantee") leased by the restaurant business formerly owned by Bob Evans (the “Bob Evans Restaurant Business”). The Guarantee remained in effect following the Company’s acquisition of Bob Evans. In the event the Bob Evans Restaurant Business fails to meet its payment and performance obligations under these leases, the Company may be required to make rent and other payments to the landlord under the requirements of the Guarantee. Should the Company, as guarantor of the lease obligations, be required to make all lease payments due for the remaining term of the leases subsequent to December 31, 2018, the maximum amount the Company may be required to pay is equal to the annual rent amount for the remainder of the lease terms. The current annual rent on these leases is $13.5 and will increase up to 1.5% annually based on indexed inflation. The lease terms extend for approximately 17 years from December 31, 2018, and the Guarantee would remain in effect in the event the leases are extended for a renewal period. In the event the Company is obligated to make payments under the Guarantee, the Company believes its exposure is limited due to protections and recourse available in the leases associated with the leased properties, including a requirement of the landlord to mitigate damages by re-letting the properties in default. The Bob Evans Restaurant Business continues to meet its obligations under these leases, and there have been no events that would indicate the obligations will not continue to be met. As such, the Company believes the fair value of the Guarantee is immaterial as of December 31, 2018.

Legal Proceedings

Antitrust claims

In late 2008 and early 2009, approximately 22 class action lawsuits were filed in various federal courts against Michael Foods, Inc. (“MFI”), a wholly owned subsidiary of the Company, and approximately 20 other defendants (producers of shell eggs and egg products, and egg industry organizations), alleging violations of federal and state antitrust laws in connection with the production and sale of shell eggs and egg products, and seeking unspecified damages. All cases were transferred to the Eastern District of Pennsylvania for coordinated and/or consolidated pretrial proceedings.

The case involved three plaintiff groups: (i) a nationwide class of direct purchasers of shell eggs (“direct purchaser class”); (ii) individual companies (primarily large grocery chains and food companies that purchase considerable quantities of eggs) that opted out of various settlements and filed their own complaints related to their purchases of shell eggs and egg products (“opt-out plaintiffs”); and (iii) indirect purchasers of shell eggs (“indirect purchaser plaintiffs”).

Resolution of claims: To date, MFI has resolved the following claims, including all class claims: (i) in December 2016, MFI settled all claims asserted against it by the direct purchaser class for a payment of $75.0, which was approved by the district court in December 2017; (ii) MFI settled all claims asserted against it by opt-out plaintiffs related to shell egg purchases on confidential terms in January 2017; and (iii) in June 2018, MFI settled all claims asserted against it by indirect purchaser plaintiffs on confidential terms. MFI has at all times denied liability in this matter, and no settlement contains any admission of liability by MFI.

Remaining portion of the case: MFI remains a defendant only with respect to claims that seek damages based on purchases of egg products by six opt-out plaintiffs. The district court had granted summary judgment precluding any claims for egg products purchases by such opt-out plaintiffs, but the Third Circuit Court of Appeals reversed and remanded these claims for further pre-trial proceedings. Defendants have filed a second motion for summary judgment seeking dismissal of the claims, and that motion is currently pending.

Although the likelihood of a material adverse outcome in the egg antitrust litigation has been significantly reduced as a result of the MFI settlements described above, the remaining portion of the case could still result in a material adverse outcome.

No expense was recorded related to these matters in the three months ended December 31, 2018 or 2017. At December 31, 2018 and September 30, 2018, the Company had $6.0 accrued for this matter, which was included in “Other current liabilities” on the Condensed Consolidated Balance Sheets. The Company records reserves for litigation losses in accordance with ASC Topic 450, “Contingencies.” Under ASC Topic 450, a loss contingency is recorded if a loss is probable and can be reasonably estimated. The Company records probable loss contingencies based on the best estimate of the loss. If a range of loss can be reasonably estimated, but no single amount within the range appears to be a better estimate than any other amount within the range, the minimum amount in the range is accrued. These estimates are often initially developed earlier than when the ultimate loss is known, and the estimates are adjusted if additional information becomes known. Although the Company believes its accruals for this matter are appropriate, the final amounts required to resolve such matter could differ materially from recorded estimates and the Company’s financial position, results of operations and cash flows could be materially affected.

Under current law, any settlement paid, including the settlements with the direct purchaser plaintiffs, the opt-out plaintiffs and the indirect purchaser plaintiffs, is deductible for federal income tax purposes.

Bob Evans Appraisal Proceedings

Prior to completion of the Company’s acquisition of Bob Evans on January 12, 2018, Bob Evans received demands from certain stockholders demanding appraisal of their shares of Bob Evans common stock. After the completion of the acquisition, several such former stockholders filed petitions in the Delaware Court of Chancery (Arbitrage Fund v. Bob Evans Farms, Inc. filed on January 23, 2018; Blue Mountain Credit Alternatives Master Fund L.P., et al. v. Bob Evans Farms, Inc. filed on April 30, 2018; and 2017 Clarendon LLC, et al. v. Bob Evans Farms, Inc. filed on April 30, 2018) seeking appraisal of their shares of Bob Evans common stock pursuant to Section 262 of the Delaware General Corporation Law (“Section 262”). The lawsuits seek appraisal for such shares, plus statutory interest, as well as the costs of the proceedings and such other relief as appropriate. Under Section 262, persons who were stockholders at the time of the closing are entitled to have their shares appraised by the Delaware Court of Chancery and receive payment of the “fair value” of such shares (plus statutory interest) as determined by the Delaware Court of Chancery. In May 2018, the court consolidated the lawsuits into one action.

In December 2018, the Company settled with one petitioner, Arbitrage Fund, and Arbitrage Fund was dismissed with prejudice from the consolidated action. In addition, in December 2018, the Company pre-paid the $77.00 per share merger consideration to the Blue Mountain and 2017 Clarendon petitioners, effectively stopping the continued accrual of statutory interest on that amount. The Company made total payments of $257.6 related to these matters in December 2018. However, the consolidated action remains active with respect to the determination of the fair value of the shares formerly held by the two remaining petitioners.

Approximately 2.5 shares of Bob Evans common stock are before the court for appraisal in the consolidated action. As of completion of the acquisition, former Bob Evans stockholders can no longer submit new demands for appraisal. All other former stockholders have been paid for their shares. The Company intends to vigorously defend the consolidated action.

At September 30, 2018, former holders of 3.3 shares of Bob Evans common stock had not withdrawn their appraisal demands and had not been paid for their shares of Bob Evans common stock. Related to these shares, the Company accrued $267.0 at September 30, 2018, which was the number of shares of Bob Evans common stock for which former Bob Evans stockholders demanded appraisal and had not withdrawn their demands multiplied by the $77.00 per share merger consideration, plus statutory interest. At December 31, 2018, former holders of 2.5 shares of Bob Evans common stock had not withdrawn their appraisal demands. At December 31, 2018, the Company had a remaining accrual of $13.7, which represents the accrued statutory interest related to the 2.5 shares for which the $77.00 per share merger consideration was paid. Additional payments related to these 2.5 shares could be made in the future. The liabilities were reported in “Other current liabilities” and “Other liabilities” on the Condensed Consolidated Balance Sheets at December 31, 2018 and September 30, 2018, respectively.

While the Company believes its accrual for these matters is appropriate, the final amounts required to resolve such matters could differ materially and the Company’s financial position, results of operations and cash flows could be materially affected. Accordingly, the Company cannot predict what impact, if any, these matters and any results from such matters could have on the Company’s future financial position, results of operations or cash flows.

Other

The Company is subject to various other legal proceedings and actions arising in the normal course of business. In the opinion of management, based upon the information presently known, the ultimate liability, if any, arising from such pending legal proceedings, as well as from asserted legal claims and known potential legal claims which are likely to be asserted, taking into account established accruals for estimated liabilities (if any), are not expected to be material individually or in the aggregate to the financial position, results of operations or cash flows of the Company. In addition, although it is difficult to estimate the potential financial impact of actions regarding expenditures for compliance with regulatory matters, in the opinion of management, based upon the information currently available, the ultimate liability arising from such compliance matters is not expected to be material to the financial position, results of operations or cash flows of the Company.

Leases

Historically, Bob Evans guaranteed certain payment and performance obligations associated with the leases for 143 properties (the "Guarantee") leased by the restaurant business formerly owned by Bob Evans (the “Bob Evans Restaurant Business”). The Guarantee remained in effect following the Company’s acquisition of Bob Evans. In the event the Bob Evans Restaurant Business fails to meet its payment and performance obligations under these leases, the Company may be required to make rent and other payments to the landlord under the requirements of the Guarantee. Should the Company, as guarantor of the lease obligations, be required to make all lease payments due for the remaining term of the leases subsequent to December 31, 2018, the maximum amount the Company may be required to pay is equal to the annual rent amount for the remainder of the lease terms. The current annual rent on these leases is $13.5 and will increase up to 1.5% annually based on indexed inflation. The lease terms extend for approximately 17 years from December 31, 2018, and the Guarantee would remain in effect in the event the leases are extended for a renewal period. In the event the Company is obligated to make payments under the Guarantee, the Company believes its exposure is limited due to protections and recourse available in the leases associated with the leased properties, including a requirement of the landlord to mitigate damages by re-letting the properties in default. The Bob Evans Restaurant Business continues to meet its obligations under these leases, and there have been no events that would indicate the obligations will not continue to be met. As such, the Company believes the fair value of the Guarantee is immaterial as of December 31, 2018.
