Revenue from Contract with Customer [Abstract]
Revenue Recognition, Policy	Revenue Recognition Accounting Policy We recognize revenue in an amount that reflects the consideration that is expected to be received for goods or services when our performance obligations are satisfied by transferring control of those promised goods or services to our customers. ASC 606 defines a five-step process to recognize revenue that requires judgment and estimates, including identifying the contract with the customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations in the contract and recognizing revenue as the performance obligation is satisfied. Revenues from Wholesale product sales are recognized when control is transferred, which typically happens upon shipment. Typically, invoicing, shipping and customer receipt of Wholesale product occur on the same business day. Discounts and allowances provided to customers are recognized as a reduction in Net sales as control of the products is transferred to customers. We recognize freight revenue related to transportation of product sales when control of the product is transferred. Revenues from Retail product sales are recognized at the point of sale upon customer check-out. Sales tax is excluded from Net sales. Limited rights of return exist with our customers due to the nature of the products we sell. Advertising income earned from our franchisees that participate in our Retail advertising program are recognized as Net sales. We recognize loyalty program expense in the form of fuel rewards as a reduction of Net sales. Product sales We enter into Wholesale supply, customer, and rebate agreements that provide terms and conditions of our order fulfillment. Our supply and rebate agreements often specify levels of required minimum purchases in order to earn certain rebates or incentives. Certain contracts include rebates and other forms of variable consideration, including rebates provided up-front, over time or at the end of a contract term. Certain customer agreements provide for the right to license one or more of our tradenames, such as FESTIVAL FOODS^®, SENTRY^®, COUNTY MARKET^®, NEWMARKET^®, FOODLAND^®, JUBILEE^® and SUPERVALU^®. We do not separately charge for the right to license our tradenames. We believe that these tradenames are capable of being distinct, but are not capable of being distinct within the context of the contracts with our customers. Accordingly, we do not separately recognize revenue related to tradenames utilized by our customers. In addition, we enter into franchise agreements that separately charge our customers, who we also provide wholesale product supply to, for the right to use our CUB FOODS^® tradename. We recognize franchise agreement revenue within Net sales. We enter into distribution agreements with manufacturers to provide wholesale supply to the Defense Commissary Agency (“DeCA”) and other government agency locations. DeCA contracts with manufacturers to obtain grocery products for the commissary system. We contract with manufacturers to distribute products to the commissaries after being authorized by the manufacturers to be a military distributor to DeCA. We must adhere to DeCA’s delivery system procedures governing matters such as product identification, ordering and processing, information exchange and resolution of discrepancies. DeCA identifies the manufacturer with which an order is to be placed, determines which distributor is contracted by the manufacturer for a particular commissary or exchange location, and then places a product order with that distributor that is covered under DeCA’s master contract with the applicable manufacturer. We supply product from our existing inventory, deliver it to the DeCA designated location, and bill the manufacturer for the product price plus a drayage fee. The manufacturer then bills DeCA under the terms of its master contract. We recognize revenue when control of the product passes to the DeCA designated location. In transactions for goods or services where we engage third-parties to participate in our order fulfillment process, we evaluate whether we are the principal or an agent in the transaction. Our analysis considers whether we control the goods or services before they are transferred to our customer, including an evaluation of whether we have the ability to direct the use of, and obtain substantially all the remaining benefits from, the specified good or service before it is transferred to our customer. Agent transactions primarily reflect circumstances where we are not involved in order fulfillment or where we are involved in the order fulfillment but are not contractually obligated to purchase the related goods or services from vendors, and instead extend Wholesale customers credit by paying vendor trade accounts payable and do not control products prior to their sale. Under ASC 606, if we determine that we are acting in an agent capacity, we record transactions on a net basis. If we determine that we are acting in a principal capacity, we record transactions on a gross basis. We also evaluate vendor sales incentives to determine whether they reduce our transaction price with our customers. Our analysis considers which party tenders the incentive, whether the incentive reflects a direct reimbursement from a vendor, whether the incentive is influenced by or negotiated in conjunction with any other incentive arrangements and whether the incentive is subject to an agency relationship with the vendor, whether expressed or implied. Typically, when vendor incentives are offered directly by vendors to our customers, require the achievement of vendor-specified requirements to be earned by our customers, and are not negotiated by us or in conjunction with any other incentive agreement whereby we do not control the direction or earning of these incentives, then we do not reduce Net sales as part of our determination of the transaction price. In circumstances where the vendors provide us consideration to promote the sale of their goods and we determine the specific performance requirements for our customers to earn these incentives from us, we reduce Net sales for these customer incentives as part of our determination of the transaction price. Customer incentives We provide incentives to our Wholesale customers in various forms established under the applicable agreement, including advances, payments over time that are earned by achieving specified purchasing thresholds, and upon the passage of time. We typically recognize customer incentives within Other assets and Other current assets and we typically recognize customer incentive payments that are based on expected purchases over the term of the agreement within Net sales. To the extent that our transaction price for product sales includes variable consideration, such as certain of these customer incentives, we estimate the amount of variable consideration that should be included in the transaction price primarily by utilizing the expected value method. Variable consideration is included in the transaction price if it is probable that a significant future reversal of cumulative revenue under the agreement will not occur. We believe that there will not be significant changes to our estimates of variable consideration. Customer incentive assets are reviewed for impairment when circumstances exist for which we no longer expect to recover the applicable customer incentives. Professional services and equipment sales We provide our Wholesale customers with professional services, including retail store support, advertising, couponing, e-commerce, network and data hosting solutions, training and certifications classes, and administrative back-office solutions. These Wholesale services typically contain single performance obligations for each respective service, in which case such services revenues are recognized when delivered. Advertising services primarily reflect the creation and distribution of circulars and other media that are recognized upon delivery to our customer. Wholesale equipment sales are recorded as direct sales to our customers when shipped, consistent with our recognition of product sales. For Wholesale services that consist of multiple performance obligations, including any combination of our deliverables, we use our judgment to determine whether the promised deliverables are capable of being distinct and are in fact distinct. For our transition services agreements with each of Albertson’s LLC and New Albertsons’s, Inc. (collectively, the “TSA”), and for our professional services agreement with Moran Foods (the “Services Agreement”), we provide a series of bundled back-office support activities that we recognize on an as-invoiced basis. TSA revenues are invoiced based on the number of stores and distribution centers we service, which vary across the period of the contract. Services Agreement revenues are recognized based on the monthly invoices for services provided.

Discounts and allowances provided to customers are recognized as a reduction in Net sales as control of the products is transferred to customers. We recognize freight revenue related to transportation of product sales when control of the product is transferred.

Revenues from Retail product sales are recognized at the point of sale upon customer check-out. Sales tax is excluded from Net sales. Limited rights of return exist with our customers due to the nature of the products we sell. Advertising income earned from our franchisees that participate in our Retail advertising program are recognized as Net sales.

Product sales

We enter into Wholesale supply, customer, and rebate agreements that provide terms and conditions of our order fulfillment. Our supply and rebate agreements often specify levels of required minimum purchases in order to earn certain rebates or incentives. Certain contracts include rebates and other forms of variable consideration, including rebates provided up-front, over time or at the end of a contract term.

Certain customer agreements provide for the right to license one or more of our tradenames, such as FESTIVAL FOODS^®, SENTRY^®, COUNTY MARKET^®, NEWMARKET^®, FOODLAND^®, JUBILEE^® and SUPERVALU^®. We do not separately charge for the right to license our tradenames.

Accordingly, we do not separately recognize revenue related to tradenames utilized by our customers. In addition, we enter into franchise agreements that separately charge our customers, who we also provide wholesale product supply to, for the right to use our CUB FOODS^® tradename. We recognize franchise agreement revenue within Net sales.

We enter into distribution agreements with manufacturers to provide wholesale supply to the Defense Commissary Agency (“DeCA”) and other government agency locations. DeCA contracts with manufacturers to obtain grocery products for the commissary system. We contract with manufacturers to distribute products to the commissaries after being authorized by the manufacturers to be a military distributor to DeCA.

We supply product from our existing inventory, deliver it to the DeCA designated location, and bill the manufacturer for the product price plus a drayage fee. The manufacturer then bills DeCA under the terms of its master contract. We recognize revenue when control of the product passes to the DeCA designated location.

In transactions for goods or services where we engage third-parties to participate in our order fulfillment process, we evaluate whether we are the principal or an agent in the transaction. Our analysis considers whether we control the goods or services before they are transferred to our customer, including an evaluation of whether we have the ability to direct the use of, and obtain substantially all the remaining benefits from, the specified good or service before it is transferred to our customer. Agent transactions primarily reflect circumstances where we are not involved in order fulfillment or where we are involved in the order fulfillment but are not contractually obligated to purchase the related goods or services from vendors, and instead extend Wholesale customers credit by paying vendor trade accounts payable and do not control products prior to their sale. Under ASC 606, if we determine that we are acting in an agent capacity, we record transactions on a net basis. If we determine that we are acting in a principal capacity, we record transactions on a gross basis.

We also evaluate vendor sales incentives to determine whether they reduce our transaction price with our customers. Our analysis considers which party tenders the incentive, whether the incentive reflects a direct reimbursement from a vendor, whether the incentive is influenced by or negotiated in conjunction with any other incentive arrangements and whether the incentive is subject to an agency relationship with the vendor, whether expressed or implied. Typically, when vendor incentives are offered directly by vendors to our customers, require the achievement of vendor-specified requirements to be earned by our customers, and are not negotiated by us or in conjunction with any other incentive agreement whereby we do not control the direction or earning of these incentives, then we do not reduce Net sales as part of our determination of the transaction price. In circumstances where the vendors provide us consideration to promote the sale of their goods and we determine the specific performance requirements for our customers to earn these incentives from us, we reduce Net sales for these customer incentives as part of our determination of the transaction price.

Customer incentives

We provide incentives to our Wholesale customers in various forms established under the applicable agreement, including advances, payments over time that are earned by achieving specified purchasing thresholds, and upon the passage of time. We typically recognize customer incentives within Other assets and Other current assets and we typically recognize customer incentive payments that are based on expected purchases over the term of the agreement within Net sales. To the extent that our transaction price for product sales includes variable consideration, such as certain of these customer incentives, we estimate the amount of variable consideration that should be included in the transaction price primarily by utilizing the expected value method. Variable consideration is included in the transaction price if it is probable that a significant future reversal of cumulative revenue under the agreement will not occur. We believe that there will not be significant changes to our estimates of variable consideration.

Customer incentive assets are reviewed for impairment when circumstances exist for which we no longer expect to recover the applicable customer incentives.

Professional services and equipment sales

We provide our Wholesale customers with professional services, including retail store support, advertising, couponing, e-commerce, network and data hosting solutions, training and certifications classes, and administrative back-office solutions. These Wholesale services typically contain single performance obligations for each respective service, in which case such services revenues are recognized when delivered. Advertising services primarily reflect the creation and distribution of circulars and other media that are recognized upon delivery to our customer. Wholesale equipment sales are recorded as direct sales to our customers when shipped, consistent with our recognition of product sales.

For Wholesale services that consist of multiple performance obligations, including any combination of our deliverables, we use our judgment to determine whether the promised deliverables are capable of being distinct and are in fact distinct. For our transition services agreements with each of Albertson’s LLC and New Albertsons’s, Inc. (collectively, the “TSA”), and for our professional services agreement with Moran Foods (the “Services Agreement”), we provide a series of bundled back-office support activities that we recognize on an as-invoiced basis. TSA revenues are invoiced based on the number of stores and distribution centers we service, which vary across the period of the contract. Services Agreement revenues are recognized based on the monthly invoices for services provided.
