Accounting Policies [Abstract]
Summary of Significant Accounting Policies and Basis of Presentation	Note 1 – Summary of Significant Accounting Policies and Basis of Presentation Principles of Consolidation: The consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of SpartanNash Company and its subsidiaries (“SpartanNash” or “the Company”). Intercompany accounts and transactions have been eliminated. Fiscal Year: The Company’s fiscal year end is the Saturday nearest to December 31. The following discussion is as of and for the fiscal years ending or ended December 28, 2019 (“2019”), December 29, 2018 ("2018" or “current year”), December 30, 2017 (“2017” or “prior year”) and December 31, 2016 (“2016”), all of which include 52 weeks. All fiscal quarters are 12 weeks, except for the Company’s first quarter, which is 16 weeks. Use of Estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported therein. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods might differ from those estimates. Revenue Recognition: The Company recognizes revenue when it satisfies a performance obligation by transferring control of the promised goods and services to a customer, in an amount that reflects the consideration that it expects to receive in exchange for those goods or services. This is achieved through applying the following five-step model: • Identification of the contract, or contracts, with a customer • Identification of the performance obligations in the contract • Determination of the transaction price • Allocation of the transaction price to the performance obligations in the contract • Recognition of revenue when, or as, the Company satisfies a performance obligation The Company generates substantially all of its revenue from contracts with customers, whether formal or implied. Sales taxes collected from customers are remitted to the appropriate taxing jurisdictions and are excluded from sales revenue as the Company considers itself a pass-through conduit for collecting and remitting sales taxes, with the exception of taxes assessed during the procurement process of select inventories. Greater than 99% of the Company’s revenues are recognized at a point in time. Revenues from product sales are recognized when control of the goods is transferred to the customer, which occurs at a point in time, typically upon delivery or shipment to the customer, depending on shipping terms, or upon customer check-out in a corporate owned retail store. Freight revenues are also recognized upon delivery, at a point in time. Other revenues, including revenues from value-added services, are recognized as earned, over a period of time. All of the Company’s revenues are domestic, as the Company has no performance obligations on international shipments subsequent to delivery to the domestic port. The Company evaluates whether it is the principal (i.e., report revenues on a gross basis) or agent (i.e., report revenues on a net basis) with respect to each contract with customers. Based upon the nature of the products the Company sells, its customers have limited rights of return which are immaterial. Discounts provided by the Company to customers at the time of sale are recognized as a reduction in sales as the products are sold. Certain contracts include rebates and other forms of variable consideration, including up-front rebates, rebates in arrears, rebatable incentives, flex funds, and product incentives, which may have tiered structures based on purchase volumes and which are accounted for as variable consideration. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Cost of Sales: Cost of sales represents the cost of inventory sold during the period, which for all non-production operations includes purchase costs, in-bound freight, physical inventory adjustments, markdowns and promotional allowances and excludes warehousing costs, depreciation and other administrative expenses. For the Company’s food processing operations, cost of sales includes direct product and production costs, inbound freight, purchasing and receiving costs, utilities, depreciation, and other indirect production costs and excludes out-bound freight and other administrative expenses. As a result, the Company’s cost of sales and gross profit may not be identical to similarly titled measures reported by other companies. Vendor allowances and credits that relate to the Company’s buying and merchandising activities consist primarily of promotional allowances, which are generally allowances on purchased quantities and, to a lesser extent, slotting allowances, which are billed to vendors for the Company’s merchandising costs such as setting up warehouse infrastructure. Vendor allowances are recognized as a reduction in cost of sales when the related product is sold. Lump sum payments received for multi-year contracts are amortized over the life of the contracts based on contractual terms. The distribution segments include shipping and handling costs in the selling, general and administrative section of operating expenses on the consolidated statement of operations. Cash and Cash Equivalents: Cash and cash equivalents consist of cash and highly liquid investments with an original maturity of three months or less at the date of purchase. Accounts and Notes Receivable: Accounts and notes receivable are shown net of allowances for credit losses of $4.3 million and $2.0 million as of December 29, 2018 and December 30, 2017, respectively. The Company evaluates the adequacy of its allowances by analyzing the aging of receivables, customer financial condition, historical collection experience, the value of collateral and other economic and industry factors. Actual collections may differ from historical experience, and if economic, business or customer conditions deteriorate significantly, adjustments to these reserves may be required. When the Company becomes aware of factors that indicate a change in a specific customer’s ability to meet its financial obligations, the Company records a specific reserve for credit losses. Operating results include bad debt expense of $3.4 million, $1.5 million and $1.4 million for 2018, 2017 and 2016, respectively. Inventory Valuation: Inventories are valued at the lower of cost or market. Approximately 88.9% and 86.9% of the Company’s inventories were valued on the last-in, first-out (LIFO) method at December 29, 2018 and December 30, 2017, respectively. If replacement cost had been used, inventories would have been $55.1 million and $50.4 million higher at December 29, 2018 and December 30, 2017, respectively. The replacement cost method utilizes the most current unit purchase cost to calculate the value of inventories. During 2018, 2017 and 2016, certain inventory quantities were reduced. The reductions resulted in liquidation of LIFO inventory carried at lower costs prevailing in prior years, the effect of which decreased the LIFO provision in 2018 by $1.1 million, and in 2017 and 2016 by $0.2 million. The Company accounts for its Food Distribution and Military inventory using a perpetual system and utilizes the retail inventory method (“RIM”) to value inventory for center store products in the Retail segment. Under RIM, inventory is stated at cost with cost of sales and gross margin calculated by applying a cost ratio to the retail value of inventories. Fresh, pharmacy and fuel products are accounted for at cost in the Retail segment. The Company evaluates inventory shortages throughout the year based on actual physical counts in its facilities. The Company records allowances for inventory shortages based on the results of recent physical counts to provide for estimated shortages from the last physical count to the financial statement date. Goodwill and Intangible Assets: Goodwill represents the excess purchase price over the fair value of tangible net assets acquired in business combinations after amounts have been allocated to intangible assets. Goodwill is not amortized, but is reviewed for impairment during the last quarter of each year, or whenever events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount, using a discounted cash flow model and comparable market values of each reporting segment. Measuring the fair value of reporting units is a Level 3 measurement under the fair value hierarchy. See Note 8, Fair Value Measurements, for a discussion of levels. Intangible assets primarily consist of trade names, customer relationships, favorable lease agreements, pharmacy prescription lists, non-compete agreements, liquor licenses and franchise fees. The following assets are amortized on a straight-line basis over the period of time in which their expected benefits will be realized: favorable leases (related lease terms), prescription lists and customer relationships (period of expected benefit reflecting the pattern in which the economic benefits are consumed), non-compete agreements and franchise fees (length of agreements), and trade names with definite lives (expected life of the assets). Indefinite-lived trade names are not amortized but are tested at least annually for impairment, and liquor licenses are also not amortized as they have indefinite lives. Intangible assets are included in “Other Assets, net” in the consolidated balance sheets. Property and Equipment: Property and equipment are recorded at cost. Expenditures which improve or extend the life of the respective assets are capitalized, whereas expenditures for normal repairs and maintenance are charged to operations as incurred. Depreciation expense on land improvements, buildings and improvements, and equipment is computed using the straight-line method as follows: Land improvements 15 years Buildings and improvements 15 to 40 years Equipment 3 to 15 years Property under capital leases and leasehold improvements are amortized on a straight-line basis over the shorter of the remaining terms of the leases or the estimated useful lives of the assets. Internal use software is included in property and equipment and amounted to $33.5 million and $30.7 million as of December 29, 2018 and December 30, 2017, respectively. Impairment of Long-Lived Assets: The Company reviews and evaluates long-lived assets for impairment when events or circumstances indicate that the carrying amount of an asset may not be recoverable. When the undiscounted expected future cash flows are not sufficient to recover an asset’s carrying amount, the fair value is compared to the carrying value to determine the impairment loss to be recorded. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value, less the cost to sell. Fair values are determined by independent appraisals or expected sales prices based upon market participant data developed by third party professionals or by internal licensed real estate professionals. Estimates of future cash flows and expected sales prices are judgments based upon the Company’s experience and knowledge of operations. These estimates project cash flows several years into the future and are affected by changes in the economy, real estate market conditions and inflation. Reserves for Closed Properties: The Company records reserves for closed properties that are subject to long-term lease commitments based upon the future minimum lease payments and related ancillary costs from the date of closure to the end of the remaining lease term, net of estimated sublease rentals that could be reasonably expected to be obtained for the property. Future cash flows are based on contractual lease terms and knowledge of the geographic area in which the closed site is located. These estimates are subject to multiple factors, including inflation, ability to sublease the property and other economic conditions. Internally developed estimates of sublease rentals are based upon the geographic areas in which the properties are located, the results of previous efforts to sublease similar properties, and the current economic environment. The reserved expenses are paid over the remaining lease terms, which range from one to 10 years. Adjustments to closed property reserves primarily relate to changes in subtenant income or actual exit costs differing from original estimates. Adjustments are made for changes in estimates in the period in which the changes become known. The current portion of the future lease obligations of stores is included in “Other accrued expenses,” and the long-term portion is included in “Other long-term liabilities” in the consolidated balance sheets. Debt Issuance Costs : Debt issuance costs are amortized over the term of the related financing agreement and are included as a direct deduction from the carrying amount of the related debt liability in “Long-term debt and capital lease obligations” in the consolidated balance sheets. Insurance Reserves: SpartanNash is self-insured through self-insurance retentions or high deductible programs for workers’ compensation, general liability, and automobile liability, and is also self-insured for healthcare costs. Self-insurance liabilities are recorded based on claims filed and an estimate of claims incurred but not yet reported. Workers’ compensation, general liability and automobile liabilities are actuarially estimated based on available historical information on an undiscounted basis. The Company has purchased stop-loss coverage to limit its exposure to any significant exposure on a per claim basis for its self-insurance retentions and high deductible programs. On a per claim basis, the Company’s exposure is up to $0.5 million for workers’ compensation and general liability, $1.0 million for automobile liability and $0.5 million for healthcare per covered life per year. A summary of changes in the Company’s self-insurance liability is as follows: (In thousands) 2018 2017 2016 Balance at beginning of year $ 15,155 $ 14,730 $ 14,466 Expenses 49,532 54,748 49,560 Claim payments, net of employee contributions (50,396 ) (54,323 ) (49,296 ) Balance at end of year $ 14,291 $ 15,155 $ 14,730 The current portion of the self-insurance liability was $8.6 million and $8.7 million as of December 29, 2018 and December 30, 2017, respectively, and is included in “Other accrued expenses” in the consolidated balance sheets. The long-term portion was $5.7 million and $6.5 million as of December 29, 2018 and December 30, 2017, respectively, and is included in “Other long-term liabilities” in the consolidated balance sheets. Income Taxes: Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future. Such deferred income tax asset and liability computations are based on enacted tax laws and rates applicable to periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized. Income tax expense is the tax payable or refundable for the period plus or minus the change during the period in deferred and other tax assets and liabilities. Earnings per share: Earnings per share (“EPS”) is computed using the two-class method. The two-class method determines EPS for each class of common stock and participating securities according to dividends and their respective participation rights in undistributed earnings. Participating securities include non-vested shares of restricted stock in which the participants have non-forfeitable rights to dividends during the performance period. Diluted EPS includes the effects of stock options. The following table sets forth the computation of basic and diluted EPS for continuing operations: (In thousands, except per share amounts) 2018 2017 2016 Numerator: Earnings (loss) from continuing operations $ 33,791 $ (52,617 ) $ 57,056 Adjustment for (earnings) loss attributable to participating securities (746 ) 908 (1,011 ) Earnings (loss) from continuing operations used in calculating earnings per share $ 33,045 $ (51,709 ) $ 56,045 Denominator: Weighted average shares outstanding, including participating securities 36,012 37,419 37,483 Adjustment for participating securities (795 ) (646 ) (664 ) Shares used in calculating basic earnings per share 35,217 36,773 36,819 Effect of dilutive stock options 10 — 73 Shares used in calculating diluted earnings per share 35,227 36,773 36,892 Basic earnings (loss) per share from continuing operations $ 0.94 $ (1.41 ) $ 1.52 Diluted earnings (loss) per share from continuing operations $ 0.94 $ (1.41 ) $ 1.52 Weighted average shares issuable upon the exercise of stock options that were not included in the EPS calculations because they were anti-dilutive were 75,159 for 2017. There were no anti-dilutive stock options in 2018 or 2016. Stock-Based Compensation: All share-based payments to associates are recognized in the consolidated financial statements as compensation cost based on the fair value on the date of grant. The grant date closing price per share of SpartanNash stock is used to estimate the fair value of restricted stock awards and restricted stock units. The value of the portion of awards expected to vest is recognized as expense over the requisite service period. Shareholders’ Equity: The Company’s restated articles of incorporation provide that the Board of Directors may at any time, and from time to time, provide for the issuance of up to 10 million shares of preferred stock in one or more series, each with such designations as determined by the Board of Directors. At December 29, 2018 and December 30, 2017, there were no shares of preferred stock outstanding. Advertising Costs: The Company’s advertising costs are expensed as incurred and are included in Selling, general and administrative expenses. Advertising expenses were $40.9 million, $43.4 million and $46.6 million in 2018, 2017 and 2016, respectively. Accumulated Other Comprehensive Income (Loss)(“AOCI”): The Company reports comprehensive income (loss) that includes net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) refers to expenses, gains and losses that are not included in net earnings, such as pension and other postretirement liability adjustments, but rather are recorded directly to shareholders’ equity. These amounts are also presented in the consolidated statements of comprehensive income. As of December 29, 2018 and December 30, 2017, AOCI relates to the pension and postretirement plans. Discontinued operations: Certain of the Company’s Food Distribution and Retail operations have been recorded as discontinued operations. Results of discontinued operations are excluded from the accompanying notes to the consolidated financial statements for all periods presented, unless otherwise noted. Results of discontinued operations reported on the consolidated statements of operations are reported net of tax. Adoption of New Accounting Standards and Recently Issued Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers – Topic 606” (“ASC 606”). The new guidance affects any reporting organization that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. As of the beginning of 2018, the Company adopted ASC 606 and all subsequent ASUs that modified ASC 606. Refer to Note 3, Revenue Recognition, for additional information about adoption of this guidance and additional disclosures required under the standard. From a principal versus agent perspective, the Company determined that certain contracts in the Food Distribution segment that were historically reported on a gross basis are now required to be reported on a net basis, resulting in a corresponding decrease to both net sales and cost of sales of $177.1 million in 2018 from what would have been recognized under previous guidance. The implementation of the guidance had no impact on gross profit, net earnings, the balance sheet, cash flows, equity, or the timing of revenue recognition in current or prior periods. The adoption of the guidance using the full retrospective method resulted in decreases to fiscal 2017 and 2016 net sales and cost of sales previously reported as shown in the following table: Full Year 4th Quarter 3rd Quarter 2nd Quarter 1st Quarter (In thousands) (52 Weeks) (12 Weeks) (12 Weeks) (12 Weeks) (16 Weeks) 2017 $ 164,283 $ 38,725 $ 38,246 $ 38,510 $ 48,802 2016 $ 173,516 $ 43,168 $ 42,382 $ 38,594 $ 49,372 In March 2017, the FASB issued ASU 2017-07, “Compensation – Retirement Benefits.” ASU 2017-07 requires that the service cost component of pension and postretirement benefit costs be presented in the same line item as other current employee compensation costs and other components of those benefit costs be presented separately from the service cost component and outside a subtotal of income from operations, if presented. The ASU also requires that only the service cost component of pension and postretirement benefit costs is eligible for capitalization. The Company adopted this guidance as of the beginning of 2018. Accordingly, benefit costs other than service cost, are reflected in the condensed consolidated statements of earnings in Other, net, whereas they previously were recognized in Selling, general and administrative expenses. Retrospective application resulted in a decrease to Other, net and an increase in Selling, general and administrative expenses. The costs associated with the reclassifications were not material in any of the periods presented. In August 2018, the FASB issued ASU 2018-15, “Intangibles – Goodwill and Other – Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract” in order to provide additional guidance on the accounting for costs of implementation activities performed in a cloud computing arrangement that is a service contract. This is an amendment to ASU 2015-05, “Intangibles—Goodwill and Other—Internal-Use Software: Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company early adopted this guidance retrospectively as of the beginning of fiscal 2018, as permitted by the amendment. The adoption of this guidance did not have a significant effect on the Company’s financial statements. In August 2018, the FASB issued ASU 2018-14, “Compensation—Retirement Benefits—Defined Benefit Plans—General: Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans.” The amendments in this ASU remove disclosures that are no longer considered to be cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The amendments in ASU 2018-14 are effective for fiscal years ending after December 15, 2020 and will be applied on a retrospective basis to all periods presented. The adoption of this guidance is not expected to have a significant effect on the Company’s financial statements. In January 2017, the FASB issued ASU 2017-01, “Business Combinations – Clarifying the Definition of a Business.” ASU 2017-01 narrows the definition of a business and provides a screen to determine when a set of the three elements of a business – inputs, processes, and outputs – are not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. If the screen is not met, the amendments (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The amendments provide a framework to assist entities in evaluating whether both an input and a substantive process are present. The guidance was effective for the Company as of the beginning of 2018. As no business combinations have occurred in 2018, there has been no impact on the consolidated financial statements for the current year. The adoption has no impact on the Company’s historical financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases.” The FASB subsequently issued ASU’s 2018-01, 2018-10, and 2018-11, which include clarifications and provide various practical expedients and transition options related to ASU 2016-02. ASU 2016-02 provides guidance for lease accounting and stipulates that lessees will need to recognize a right-of-use asset and a lease liability for substantially all leases (other than leases that meet the definition of a short-term lease). The liability will be equal to the present value of lease rent payments. Treatment in the consolidated statements of operations will be similar to the current treatment of operating and capital leases. The Company adopted the standard as of December 30, 2018, the beginning of fiscal 2019. The Company has elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allows for the carryforward of the historical lease classification. In addition, the Company has elected the hindsight practical expedient to reassess the reasonably certain lease term for existing leases. The election of the hindsight practical expedient will result in the extension or reduction of lease terms for certain existing leases, and adjustments to the useful lives of corresponding leasehold improvements. The Company will make an accounting policy election not to record lease liabilities or right of use assets for short-term leases, those with an initial minimum term of less than one year. The adoption of the standard will result in a recognition of additional lease assets and lease liabilities of approximately $240 million and $290 million, respectively, as of December 30, 2018, and a transition adjustment recorded to beginning of the year retained earnings of approximately $27 million (net of deferred tax impact of $9 million). The transition adjustment relates to impairment of right of use assets in transition and the impact of hindsight on the evaluation of lease term. Remaining differences between lease assets and liabilities relate to the derecognition of existing lease-related liabilities and assets recorded under ASC 840, which were included in beginning lease liabilities under ASC 842. The Company does not believe the new standard will have an impact on liquidity or on debt-covenant compliance under the current agreements.

Business Combinations [Abstract]
Acquisitions	Note 2 – Acquisitions On January 6, 2017, the Company acquired certain assets and assumed certain liabilities of Caito Foods Service (“Caito”) and Blue Ribbon Transport (“BRT”) for $214.6 million in cash, net of $2.5 million of cash acquired. Acquired assets consist primarily of property and equipment of $76.7 million, intangible assets of $72.9 million, and working capital. Intangible assets are primarily composed of customer relationships, which are amortized over fifteen years, and indefinite lived trade names. In connection with the purchase, the Company provided certain earn-out opportunities that have the potential to pay the sellers an additional $27.4 million, collectively, if the business achieves certain performance targets during the first three years after acquisition. As certain performance targets were not met in the first year after acquisition, the Company will be reimbursed a portion of the initial purchase price at an amount not to exceed the sum of: a) $15.0 million, representing the funds paid into escrow, and b) any earn-out opportunities earned by the sellers. The reduction in purchase price will first be applied to funds paid into escrow and then as an offset against and a reduction to any payments owed on the various earn-out opportunities, with reimbursement made once the parties agree on the measurement of performance against the targets. The Caito is a leading supplier of

Revenue From Contract With Customer [Abstract]
Revenue	Note 3 – Revenue Sources of Revenue The Company’s main sources of revenue include the following: Customer Supply Agreements (CSAs) – The Company enters into CSAs (also known as Retail Sales and Service Agreements) with many of its retailer customers. These contracts obligate the Company to supply grocery and related products upon receipt of a purchase order from its customers. The contracts often specify minimum purchases a customer is required to make - in dollars or as a percentage of their total purchases - in order to earn certain rebates or incentives. In some cases, customers are required to repay certain advanced or loaned funds if they fail to meet purchase minimums or otherwise exit the supply agreement. Many of these contracts include various performance obligations other than providing grocery products, such as providing store resets, shelf tags, signage, or merchandising services. The Company has determined that these obligations are not material in the overall context of the contracts, and as such has not allocated transaction price to these obligations. Revenue is recognized under these contracts when control of the product passes to the customer, which may happen before or after delivery depending upon specified shipping terms. Contracts with Manufacturers and Brokers to supply the Defense Commissary Agency (“DeCA”) and Other Government Agencies – DeCA operates a chain of 237 commissaries on U.S. military installations. DeCA contracts with manufacturers to obtain grocery products for the commissary system. Manufacturers either deliver the products to the commissaries themselves or, more commonly, contract with distributors such as SpartanNash to provide products to the commissaries. Manufacturers must authorize the distributors as their official representatives to DeCA, and the distributors must adhere to DeCA’s frequent delivery system (“FDS”) procedures governing matters such as product identification, ordering and processing, information exchange and resolution of discrepancies. The Company obtains distribution contracts with manufacturers through competitive bidding processes and direct negotiations. As commissaries need to be restocked, DeCA identifies the manufacturer with which an order is to be placed, determines which distributor is the manufacturer’s official representative for a particular commissary or exchange location, and then places a product order with that distributor under the auspices of DeCA’s master contract with the applicable manufacturer. The distributor selects that product from its existing inventory, delivers it to the commissary or port (in the case of overseas shipments) designated by DeCA, and bills the manufacturer for the product price plus a drayage fee that is typically based on a percentage of the purchase price, but may in some cases be based on a dollar amount per case or pound of product sold. The manufacturer then bills DeCA under the terms of its master contract. As control of the product passes to the customer upon delivery, revenue is recognized by SpartanNash at this point in time. Revenue is recognized for the full amount paid by the vendor (for product and drayage) as the Company is a principal in the transaction and therefore should recognize revenue on a gross basis for these contracts. The FASB’s definition of a principal in the transaction is centered on controlling goods before they are transferred to the customer. Key considerations supporting that SpartanNash controls the goods for these contracts prior to transfer to the customer include the following: the Company has the ability to obtain substantially all of the remaining benefits from the assets by selling the goods and/or by pledging the related assets as collateral for borrowings, the Company is required to bear the risk of inventory loss prior to transfer to the customer, has shared responsibilities in the fulfillment and acceptability of the goods, and to a lesser extent, has some discretion in establishing the price for the goods sold to DeCA. Based on a thorough evaluation of all of the facts and circumstances, including a detailed assessment and interpretation of the revenue standard, the Company concluded that it is a principal in the transaction and should recognize revenue on a gross basis for these contracts. Retail Sales – The corporate owned retail stores recognize revenue at the time the customer takes possession of the goods. While there are no formal contracts related to these sales, they are within the scope of ASC 606. Customer returns are not material. The Company does not recognize a sale when it awards customer loyalty points or sells gift cards and gift certificates; rather, a sale is recognized when the customer loyalty points, gift card or gift certificate are redeemed to purchase product. There were no significant changes to revenue recognition in the Retail segment under ASC 606 related to the accounting for gift card breakage and loyalty rewards, which are immaterial to the consolidated financial statements.

(b) Fresh includes produce, meat, dairy, deli, bakery, prepared proteins, seafood and floral. (c) Non-food includes general merchandise, health and beauty care, tobacco products and pharmacy. Contract Assets and Liabilities Under its contracts with customers, the Company stands ready to deliver product upon receipt of a purchase order. Accordingly, the Company has no performance obligations under its contracts until its customers submit a purchase order. The Company does not receive pre-payment from its customers, or enter into commitments to provide goods or services that have terms greater than one year. As the performance obligation is part of a contract that has an original expected duration of less than one year, the Company has applied the practical expedient under ASC 606 to omit disclosures regarding remaining performance obligations. Revenue recognized from performance obligations related to prior periods (for example, due to changes in estimated rebates and incentives impacting the transaction price) was not material in any period presented. In the ordinary course of business, the Company may advance funds to certain independent retailers which are earned by the retailers primarily through achieving specified purchase volume requirements, as outlined in their supply agreements with the Company, or in limited instances, for remaining a SpartanNash customer for a specified time period. These advances must be repaid if the purchase volume requirements are not met or if the retailer no longer remains a customer for the specified time period. For volume-based arrangements, the Company estimates the amount of the advanced funds earned by the retailers based on the expected volume of purchases by the retailer, and amortizes the advances as a reduction of the transaction price and revenue earned. These advances are not considered contract assets under ASC 606 as they are not generated through the transfer of goods or services to the retailers. These advances are included in Other assets, net on the Company’s balance sheets. When the Company transfers goods or services to a customer, payment is due - subject to normal terms - and is not conditional on anything other than the passage of time. Typical payment terms range from due upon receipt to 30 days, depending on the type of customer and relationship. At contract inception, the Company expects that the period of time between the transfer of goods to the customer and when the customer pays for those goods will be less than one year, which is consistent with the Company’s standard payment terms. Accordingly, the Company has elected the practical expedient under ASC 606 to not adjust for the effects of a significant financing component. As such, these amounts are recorded as receivables and not contract assets. The Company had no contract assets for any period presented. Accounts and notes receivable are comprised of the following: December 29, December 30, (In thousands) 2018 2017 Customer notes receivable $ 3,130 $ 2,555 Customer accounts receivable 314,791 312,214 Other receivables 32,516 31,169 Allowance for doubtful accounts (4,177 ) (1,881 ) Net current accounts and notes receivable $ 346,260 $ 344,057 Long-term notes receivable 16,021 18,322 Allowance for doubtful accounts (120 ) (120 ) Net long-term notes receivable $ 15,901 $ 18,202 The Company does not typically incur incremental costs of obtaining a contract that are contingent upon successful contract execution and would therefore be capitalized. The Company expenses incremental costs of obtaining a contract as and when incurred if the expected amortization period of the asset that the Company would have recognized is one year or less.

Goodwill and Other Intangible Assets	Note 5 – Goodwill and Other Intangible Assets The Company has three reportable segments; however, no goodwill has existed within the Military segment. Changes in the carrying amount of goodwill were as follows: Food (In thousands) Distribution Retail Total Balance at December 31, 2016: $ 132,367 $ 190,319 (a) $ 322,686 (a) Acquisitions (Note 2) 46,281 — 46,281 Disposals — (1,292 ) (1,292 ) Impairment — (189,027 ) (189,027 ) Balance at December 30, 2017 and December 29, 2018: $ 178,648 $ — (b) $ 178,648 (b) (a) Net of accumulated impairment charges of $86.6 million. (b) Net of accumulated impairment charges of $275.6 million. The Company reviews goodwill and other intangible assets for impairment annually, during the fourth quarter of each year, and more frequently if circumstances indicate the possibility of impairment. Testing goodwill and other intangible assets for impairment requires management to make significant estimates about the Company’s future performance, cash flows, and other assumptions that can be affected by potential changes in economic, industry or market conditions, business operations, competition, or the Company’s stock price and market capitalization. In 2017, the Company experienced significantly lower than expected Retail operating results and it was determined that the carrying value of the Retail segment exceeded its fair value. Consequently, the Company recorded a goodwill impairment charge of $189.0 million in the third quarter of 2017. The Company completed its current year impairment analysis in the fourth quarter, which did not result in the identification of any goodwill impairment. The following table reflects the components of amortized intangible assets, included in “Intangible assets, net” on the consolidated balance sheets: December 29, 2018 December 30, 2017 Gross Gross Carrying Accumulated Carrying Accumulated (In thousands) Amount Amortization Amount Amortization Non-compete agreements $ 3,358 $ 886 $ 3,408 $ 397 Favorable leases 7,738 4,282 8,251 4,332 Pharmacy customer prescription lists 6,354 4,377 6,810 4,210 Customer relationships 57,937 7,835 57,937 4,173 Trade names 1,068 536 1,068 386 Franchise fees and other 1,064 422 1,047 381 Total $ 77,519 $ 18,338 $ 78,521 $ 13,879 The weighted average amortization periods for amortizable intangible assets as of December 29, 2018 are as follows: Non-compete agreements 6.3 years Favorable leases 15.2 years Pharmacy customer prescription lists 8.1 year Customer relationships 16.1 years Trade names 7.0 years Franchise fees and other 9.6 years Amortization expense for intangible assets was $5.8 million, $5.5 million and $3.0 million for 2018, 2017 and 2016, respectively.

Restructuring, asset impairment and other charges included in the consolidated statements of operations consisted of the following: (In thousands) 2018 2017 2016 Asset impairment charges $ 2,630 $ 33,679 $ 15,586 Charge on customer advance 32,000 — — Provision for closing charges 4,499 3,852 13,925 (Gain) loss on sales of assets related to closed facilities (1,352 ) 998 (134 ) Provision for severance 153 624 919 Other costs associated with distribution center and store closings 797 1,851 3,692 Changes in estimates (1,181 ) 1,028 865 Lease termination adjustments — (2,600 ) (2,737 ) $ 37,546 $ 39,432 $ 32,116 The charge on the customer advance relates to an independent retailer customer which is not expected to be fully recoverable and was therefore written down to its estimated realizable value, resulting in a charge of $32.0 million. See Note 15 – Concentration of Credit Risk for further information. Asset impairment charges in all years were incurred on long-lived assets primarily in the Retail segment due to the economic and competitive environment of certain stores and in conjunction with the Company’s retail store rationalization plan. The changes in estimates primarily relate to revised estimates performed in the current year related to lease turnover, ancillary costs and sublease income associated with previously closed locations, which were lower than the previous expectations at certain properties in the current year and reflected the deterioration of the condition of certain properties in 2017 and 2016. Lease termination adjustments represent the benefits recognized in connection with lease buyouts negotiated related to previously closed stores. Long-lived assets are analyzed for impairment whenever circumstances arise that could indicate the carrying value of long-lived assets may not be recoverable. If such circumstances exist, the Company estimates future cash flows expected from the use of the assets and any proceeds from their eventual disposition. If the sum of the expected cash flows (undiscounted and without interest charges) is less than the carrying amount of the asset, an impairment loss is recognized in the consolidated statements of operations. Measurement of the impairment loss is equal to the excess of the carrying amount of the assets over the discounted future cash flows. When analyzing the assets for impairment, assets are grouped at the lowest level of identifiable cash flows that are largely independent of the cash flows of other groups of assets. Long-lived assets are measured at fair value on a nonrecurring basis using Level 3 inputs under the fair value hierarchy, as further described in Note 8, Fair Value Measurements. Assets consisting of property and equipment with a book value of $3.7 million were measured at a fair value of $1.1 million, resulting in impairment charges of $2.6 million in 2018. Assets consisting primarily of property and equipment with a book value of $48.6 million were measured at a fair value of $14.9 million, resulting in an impairment charge of $33.7 million in 2017. Fair value of long-lived assets is determined by estimating the amount and timing of net future cash flows, discounted using a risk-adjusted rate of interest. The Company estimates future cash flows based on historical results of operations, external factors expected to impact future performance, experience and knowledge of the geographic area in which the assets are located, and when necessary, uses real estate brokers.

The principal changes of the amendment included an extension of the maturity date of the loans from December 20, 2021 to December 18, 2023, the ability to increase the size of the Tranche A revolving loan to $975 million from $900 million, an amendment to the interest rate grid such that rates for the Tranche A-1 revolving loans ($40 million capacity) are now LIBOR plus 2.25% to LIBOR plus 2.50%, a reload of the Tranche A-2 term loan ($60 million capacity) and a reset of certain advance rates for the borrowing base. T Availability under the Credit Agreement is based upon advance rates on certain asset categories owned by the Company, including, but not limited to the following: inventory, accounts receivable, real estate, prescription lists, cigarette tax stamps, and rolling stock. The Credit Agreement imposes certain requirements, including: limitations on dividends and investments, limitations on the Company’s ability to incur debt, make loans, acquire other companies, change the nature of the Company’s business, enter a merger or consolidation, or sell assets. These requirements can be more restrictive depending upon the Company’s Excess Availability, as defined under the Credit Agreement. Borrowings under the three tranches of the credit facility bear interest at the Company’s option as either Eurodollar loans or Base Rate loans, . The interest rate terms for each of the aforementioned tranches are as follows Credit Outstanding as of Facility December 29, 2018 Tranche (In thousands) Eurodollar Rate Base Rate Tranche A $ 569,601 LIBOR plus 1.25% to 1.50% Greater of: (i) the Federal Funds Rate plus 0.75% to 1.00% (ii) the Eurodollar Rate plus 2.25% to 2.50% (iii) the prime rate plus 0.25% to 0.50% Tranche A-1 $ 31,251 LIBOR plus 2.25% to 2.50% Greater of: (i) the Federal Funds Rate plus 1.75% to 2.00% (ii) the Eurodollar Rate plus 2.25% to 2.50% (iii) the prime rate plus 1.25% to 1.50% Tranche A-2 $ 60,000 LIBOR plus 5.25% Greater of: (i) the Federal Funds Rate plus 4.75% (ii) the Eurodollar Rate plus 5.25% (iii) the prime rate plus 4.25% The Company also incurs an unused line of credit fee on the unused portion of the loan commitments at a rate of 0.25%. The Credit Agreement requires that the Company maintain Excess Availability of 10% of the borrowing base, as defined in the Credit Agreement. The Company is in compliance with all financial covenants as of December 29, 2018 and had Excess Availability after the 10% requirement of $262.0 million and $132.7 million at December 29, 2018 and December 30, 2017, respectively. The Credit Agreement provides for the issuance of letters of credit, of which $11.7 million and $9.2 million were outstanding as of December 29, 2018 and December 30, 2017, respectively. The weighted average interest rate for all borrowings, including loan fee amortization, was 4.08% for 2018.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 8 – Fair Value Measurements ASC 820 prioritizes the inputs to valuation techniques used to measure fair value into the following hierarchy: Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3: Unobservable inputs for the asset or liability, reflecting the reporting entity’s own assumptions about the assumptions that market participants would use in pricing. Financial instruments include cash and cash equivalents, accounts and notes receivable, accounts payable and long-term debt. The carrying amounts of cash and cash equivalents, accounts and notes receivable, and accounts payable approximate fair value because of the short-term maturities of these financial instruments. For discussion of the fair value measurements related to goodwill and long-lived asset impairment charges, refer to Note 5, Goodwill and Other Intangible Assets, and Note 6, Restructuring, Asset Impairment and Other Charges. At December 29, 2018 and December 30, 2017, the book value and estimated fair value of the Company’s debt instruments, excluding debt financing costs, were as follows: December 29, December 30, (In thousands) 2018 2017 Book value of debt instruments, excluding debt financing costs: Current maturities of long-term debt and capital lease obligations $ 18,263 $ 9,196 Long-term debt and capital lease obligations 686,594 747,172 Total book value of debt instruments 704,857 756,368 Fair value of debt instruments, excluding debt financing costs 705,875 757,966 Excess of fair value over book value $ 1,018 $ 1,598 The estimated fair value of debt is based on market quotes for instruments with similar terms and remaining maturities (Level 2 inputs and valuation techniques). Certain of the Company’s business combinations involve the potential for the receipt or payment of future contingent consideration upon the shortfall or achievement of various operating thresholds, respectively. The additional consideration is generally contingent on the acquired company reaching certain performance milestones, including attaining specified EBITDA levels. An asset or liability is recorded for the estimated fair value of the contingent consideration at the acquisition date and is re-measured each reporting period, with changes in fair value recognized as income or expense within operating expenses in the consolidated statements of operations. The Company measures the asset and liability on a recurring basis using Level 3 inputs. The fair value of contingent consideration is measured using a discounted cash flow model incorporating projected payment dates, discount rates, probabilities of payment, and projected EBITDA. Projected EBITDA amounts are based on initial deal model forecasts at the time of acquisition as well as the Company’s most recent internal operational budget and include a probability weighted range of outcomes. Changes in projected EBITDA, probabilities of payment, discount rates, or projected payment dates may result in higher or lower fair value measurements. The recurring Level 3 fair value measurements of contingent consideration include the following significant unobservable inputs as of December 29, 2018: Unobservable Input Range Discount rate 11.80% Probability of payments 0% - 100% Projected year(s) of payments 2019 As of December 29, 2018, the fair value of contingent consideration receivable and payable associated with the Caito and BRT acquisition was $18.4 million and $3.4 million, respectively. The net receivable of $15 million is recorded in other current assets

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 9 – Commitments and Contingencies The Company subleases property at certain locations and for 2018, 2017 and 2016, received rental income of $3.6 million, $3.4 million and $4.8 million, respectively. In the event of customer default, the Company would be responsible for fulfilling these lease obligations. Future payment obligations under these leases are disclosed in Note 10, Leases. Contingencies related to credit risk and collectability are disclosed in Note 15, Concentration of Credit Risk. Unions represent approximately 9% of SpartanNash’s associates. These associates are covered by collective bargaining agreements (“CBAs”). The facilities covered by CBAs, the unions representing the covered associates and the expiration dates for each existing CBA are provided in the following table: Distribution Center Locations Union Locals Expiration Dates Norfolk, Virginia IBT 822 April 2019 Columbus, Georgia IBT 528 September 2019 Grand Rapids, Michigan IBT 406 October 2019 Landover, Maryland IBT 639 February 2021 Lima, Ohio IBT 908 January 2022 Bellefontaine, Ohio GTL Truck Lines, Inc. (a) IBT 908 February 2022 Bellefontaine, Ohio General Merchandise Service Division (a) IBT 908 February 2022 (a) The Company is in the process of negotiating contract extensions at these locations, which have been updated with the contemplated expiration dates. The Company is engaged from time-to-time in routine legal proceedings incidental to its business. The Company does not believe that these routine legal proceedings, taken as a whole, will have a material impact on its business or financial condition. While the ultimate effect of such actions cannot be predicted with certainty, management believes that their outcome will not result in an adverse effect on the Company’s consolidated financial position, operating results or liquidity. The Company contributes to the Central States Southeast and Southwest Pension Fund (“Central States Plan” or “the Plan”), a multi-employer pension plan, in accordance with provisions in place in collective bargaining agreements covering its supply chain operations in Bellefontaine, Lima, and Grand Rapids. This Plan provides retirement benefits to participants based on their service to contributing employers. The benefits are paid from assets held in trust for that purpose. Trustees are appointed by contributing employers and unions; however, SpartanNash is not a trustee of the Plan. The trustees typically are responsible for determining the level of benefits to be provided to participants, as well as for such matters as the investment of the assets held in trust and the overall administration of the plan. The Company currently contributes to the Plan under the terms outlined in the “Primary Schedule” of Central States’ Rehabilitation Plan or those outlined in the “Default Schedule.” Both the Primary and Default schedules require varying increases in employer contributions over the previous year’s contribution. Increases are negotiated within each collective bargaining agreement and vary by location. The Plan continues to be in red zone status, and according to the Pension Protection Act (“PPA”), is considered to be in “critical and declining” zone status. Among other factors, plans in the “critical and declining” zone are generally less than 65% Based on the most recent information available to the Company, management believes that the present value of actuarial accrued liabilities in this multi-employer plan significantly exceeds the value of the assets held in trust to pay benefits. Because SpartanNash is one of a number of employers contributing to this plan, it is difficult to ascertain what the exact amount of the underfunding would be. Management is not aware of any significant change in funding levels since December 29, 2018. To reduce this underfunding, management expects meaningful increases in expense as a result of required incremental multi-employer pension plan contributions in future years. Any adjustment for withdrawal liability will be recorded when it is probable that a liability exists and can be reasonably determined.

Leases [Abstract]
Leases	Note 10 – Leases A portion of the Company’s retail stores and warehouses are operated in leased facilities. The Company also leases small ancillary warehouse facilities, the majority of the tractors and trailers within its fleet, and certain other equipment. Most of the property leases contain renewal options of varying terms. Terms of certain leases contain provisions requiring payment of percentage rent based on sales and payment of executory costs such as property taxes, utilities, insurance, maintenance and other occupancy costs applicable to the leased premises. Terms of certain leases of transportation equipment contain provisions requiring payment of percentage rent based upon miles driven. Certain properties or portions thereof are subleased to others. Operating leases often contain renewal options. In those locations in which it makes economic sense to continue to operate, management expects that, in the normal course of business, leases that expire will be renewed or replaced by other leases. Rental expense, net of sublease income, under operating leases consisted of the following: (In thousands) 2018 2017 2016 Minimum rentals $ 61,774 $ 55,159 $ 57,478 Contingent rent (reductions) increases (219 ) (237 ) 314 Sublease rental income (3,554 ) (3,407 ) (4,830 ) Total $ 58,001 $ 51,515 $ 52,962 The Company’s total future lease commitments under operating and capital leases in effect at December 29, 2018 are as follows: Operating Leases Used in Subleased Capital (In thousands) Operations to Others Total Leases 2019 $ 54,098 $ 1,039 $ 55,137 $ 9,091 2020 47,212 817 48,029 7,049 2021 39,887 694 40,581 5,377 2022 32,299 468 32,767 4,685 2023 25,419 357 25,776 3,912 Thereafter 75,626 147 75,773 25,152 Total $ 274,541 $ 3,522 $ 278,063 55,266 Interest (15,708 ) Present value of minimum lease obligations 39,558 Current maturities 6,840 Long-term capital lease obligations $ 32,718 Assets held under capital leases consisted of the following: December 29, December 30, (In thousands) 2018 2017 Building and improvements $ 57,326 $ 60,398 Equipment 6,889 3,727 Assets under capital leases 64,215 64,125 Less accumulated amortization and depreciation 30,774 29,518 Net assets under capital leases $ 33,441 $ 34,607 Amortization expense for property under capital leases was $4.3 million, $4.4 million and $5.2 million in 2018, 2017 and 2016, respectively. Certain retail store facilities, either owned or obtained through leasing arrangements, are leased to others. A majority of the leases provide for minimum and contingent rentals based upon stipulated sales volumes and contain renewal options. Certain of the leases contain escalation clauses.

Compensation And Retirement Disclosure [Abstract]
Associate Retirement Plans	Note 11 – Associate Retirement Plans The Company’s retirement programs include pension plans providing non-contributory benefits and salary deferral defined contribution plans. Substantially all of the Company’s associates not covered by CBAs are covered by a frozen non-contributory pension plan, a defined contribution plan, or both. Associates covered by CBAs at the Company’s Columbus, Georgia; Norfolk, Virginia; and Landover, Maryland facilities all participate in the Company’s defined contribution plan; the remaining associates covered under CBAs participate in a multi-employer pension plan. Defined Contribution Plans Expense for employer matching and profit-sharing contributions made to defined contribution plans totaled $7.0 million, $7.9 million and $11.9 million in 2018, 2017 and 2016, respectively. Executive Compensation Plans The Company has a deferred compensation plan for a select group of management personnel or highly compensated associates. The plan is unfunded and permits participants to defer receipt of a portion of their base salary, annual bonus, or long-term incentive compensation which would otherwise be paid to them. The deferred amounts, plus earnings, are distributed following the associate’s termination of employment. Earnings are based on the performance of hypothetical investments elected by the participant from a portfolio of investment options. The Company holds variable universal life insurance policies on certain key associates intended to fund distributions under the deferred compensation plan referenced above. The net cash surrender value of approximately $4.3 million at both December 29, 2018 and December 30, 2017, respectively, is recorded in “Other assets, net” in the consolidated balance sheets. These policies have an aggregate amount of life insurance coverage of approximately $15.0 million. Defined Benefit Plans The Company sponsors the SpartanNash Company Pension Plan (the “Pension Plan”), a frozen defined benefit pension plan. On February 28, 2018, the Company’s Board of Directors granted approval to proceed with terminating the frozen Pension Plan and the Plan was terminated on July 31, 2018. The Company will offer participants the option to receive an annuity or lump sum distribution which may be rolled over into another qualified plan. The distribution of assets to plan participants is expected to be completed in the third quarter of 2019. The Company will incur a one-time, pre-tax settlement charge estimated to be approximately $20 million to $21 million to recognize the deferred losses in AOCI upon distribution of the Plan assets and related recognition of the settlement as well as other termination expenses. The Company expects the Plan termination will reduce administrative fees and premium funding costs in future periods. The pension benefits are primarily based on years of service and compensation, with some differences resulting from the nature of how benefits were calculated under the Company’s legacy defined benefit plans, as described below. On December 31, 2014, the Retirement Plan for Employees of Super Food Services, Inc. (“Super Foods Plan”) was merged into the Spartan Stores, Inc. Cash Balance Pension Plan (“Cash Balance Pension Plan”) and renamed the SpartanNash Company Pension Plan. The merging of the plans resulted in lower administrative fees and reduced cash funding. Annual payments to the pension trust fund are determined in compliance with the Employee Retirement Income Security Act of 1976 (“ERISA”). As of December 29, 2018, plan assets consist principally of U.S. government and corporate obligations. The Cash Balance Pension Plan, a non-contributory cash balance pension plan, was frozen effective January 1, 2011. As a result of the freeze, no additional associates were eligible to participate in the plan after January 1, 2011, and additional service credits were no longer added to each participant’s account; however, interest credits continue to accrue. Prior to the plan freeze, the plan benefit formula utilized a cash balance approach whereby credits were added annually to a participant’s account based on compensation and years of vested service, with interest credits also added to the participant’s account at the Company’s discretion. The Super Foods Plan, a qualified non-contributory pension plan offered by one of the Company’s subsidiaries, provides retirement income for certain eligible full-time associates who are not covered by a union retirement plan. Pension benefits under the plan are based on length of service and compensation, and contributions meet the minimum funding requirements. This plan was frozen effective January 1, 1998. If lump sum distributions are made in an amount exceeding annual interest cost, settlement accounting is triggered, and the resulting settlement expense is recorded as a component of total pension expense (income). Lump sum distributions of $3.3 million, $2.6 million and $2.8 million were made and resulting pension settlement charges of $0.8 million, $0.5 million and $0.7 million were incurred in 2018, 2017 and 2016, respectively. Postretirement Medical Plans SpartanNash Company and certain subsidiaries provide healthcare benefits to retired associates under the SpartanNash Company Retiree Medical Plan (the “Retiree Medical Plan”). Former Spartan Stores, Inc. associates hired prior to January 1, 2002 who were not covered by CBAs during their employment and who have at least The following tables set forth the actuarial present value of benefit obligations, funded status, changes in benefit obligations and plan assets, weighted average assumptions used in actuarial calculations and components of net periodic benefit costs for the Company’s significant pension and postretirement benefit plans, excluding multi-employer plans. The prepaid, current accrued, and noncurrent accrued benefit costs associated with pension and postretirement benefits are reported in “Prepaid expenses and other current assets,” “Other assets, net,” “Accrued payroll and benefits,” and “Postretirement benefits,” respectively, in the consolidated balance sheets.

Assumed current healthcare cost trend rates used to determine net periodic benefit cost (income) were as follows: 2018 2017 2016 Pre-65 N/A N/A 7.50% Post-65 8.00% 8.40% 8.40% The effect of a one-percentage point increase or decrease in assumed healthcare cost trend rates on the total service and interest components and the post-retirement benefit obligations would be less than $0.1 million. Expected Return on Assets and Investment Strategy The Company has assumed an average long-term expected return on the Pension Plan assets of 2.80% as of December 29, 2018. The expected return assumption was modeled by third-party investment portfolio managers, based on asset allocations and the expected return and risk components of the various asset classes in the portfolio. Determining projected stock and bond returns and then applying these returns to the target asset allocations of the plan assets developed the expected return. Equity returns were based primarily on historical returns of the S&P 500 Index. Fixed-income projected returns were based primarily on historical returns for the broad U.S. bond market. This overall return assumption is believed to be reasonable over a longer-term period that is consistent with the liabilities. The Company has historically followed an investment policy for the Pension Plan with a long-term asset allocation mix designed to meet the long-term retirement obligations by investing in equity, fixed income and other securities to cover cash flow requirements of the plan and minimize long-term costs. In the current year, in the context of the Pension Plan termination and the expected distribution of the related assets, the Company has revised the asset mix to include a higher allocation of fixed income securities, which reduce the Pension Plan’s exposure to market volatility. Certain of the fixed income investments have a duration of 90 days or less, and as such are classified as cash equivalents. The following table summarizes both the targeted allocation of the Pension Plan’s asset allocation by asset category and actual allocations as of December 29, 2018 and December 30, 2017: Target Actual December 29, December 29, December 30, Asset Category 2018 2018 2017 Equity securities — % — % 19.3 % Fixed income 100.0 100.0 80.7 Total 100.0 % 100.0 % 100.0 % The investment policy emphasizes the following key objectives: (1) provide benefit security to participants by maximizing the return on plan assets at an acceptable risk level, (2) maintain adequate liquidity for current benefit payments, (3) avoid unexpected increases in pension expense, and (4) within the scope of the above objectives, minimize long term funding to the plan. The fair values of the Pension Plan assets at December 29, 2018 and December 30, 2017, by asset category, are as follows: Fair Value of Assets as of December 29, 2018 (In thousands) Total Level 1 Level 2 Level 3 NAV (a) Mutual funds $ 20,124 $ — $ — $ — $ 20,124 Pooled funds 29,576 — — — 29,576 Money market fund 11,992 — 11,992 — — Guaranteed annuity contracts 12,549 — — 12,549 — Total fair value $ 74,241 $ — $ 11,992 $ 12,549 $ 49,700 Fair Value of Assets as of December 30, 2017 (In thousands) Total Level 1 Level 2 Level 3 NAV (a) Mutual funds $ 18,194 $ — $ — $ — $ 18,194 Pooled funds 48,133 — — — 48,133 Money market fund 1,037 — 1,037 — — Guaranteed annuity contracts 13,891 — — 13,891 — Total fair value $ 81,255 $ — $ 1,037 $ 13,891 $ 66,327 (a) Assets are measured at net asset value (“NAV”) (or its equivalent) on a non-active market, and therefore, have not been classified in the fair value hierarchy. Level 3 assets consist of guaranteed annuity contracts. A reconciliation of the beginning and ending balances for Level 3 assets is as follows: (In thousands) December 29, 2018 December 30, 2017 Balance at beginning of year $ 13,891 $ 15,426 Purchases, sales, issuances and settlements, net (1,712 ) (2,222 ) Interest income 588 552 Unrealized gains (218 ) 135 Balance at end of year $ 12,549 $ 13,891 See Note 8 for a discussion of the levels of the fair value hierarchy. The fair value measurement level used is based on the lowest level of any input that is significant to the fair value measurement. The following is a description of the valuation methods used for the Pension Plan’s assets measured at fair value in the above tables: Money market fund: The carrying value approximates fair value. Money market funds are valued on a daily basis at NAV using the amortized cost of the securities held in the fund. Since amortized cost does not meet the criteria for an active market, money market funds are classified within Level 2 of the fair value hierarchy of ASC 820. Mutual Funds: These investments are valued using NAV as a practical expedient to estimate fair value and are not classified in the fair value hierarchy. NAV is determined once a day after the closing of the exchange based upon the underlying assets in the fund, less the fund’s liabilities, expressed on a per-share basis. Mutual funds held by the Pension Plan are open end mutual funds that are registered with the Securities and Exchange Commission (“SEC”). These funds are required to publish their daily NAV and to transact at that price. The mutual funds held by the Pension Plan are therefore deemed to be actively traded. Pooled Funds: The plan holds units of various Aon Hewitt Group Trust Funds offered through a private placement. The units are valued daily using NAV as a practical expedient to estimate fair value. NAVs are based on the fair value of each fund’s underlying investments and are not classified in the fair value hierarchy. The practical expedient is not used when it is determined to be probable that the investment will be sold for an amount different than the reported NAV. Guaranteed Annuity Contracts: The guaranteed annuity contracts are immediate participation contracts held with insurance companies that act as custodian of the Pension Plan’s assets. The guaranteed annuity contracts are stated at contract values, which are determined by the custodians and approximate fair values. The Company evaluates the general financial condition of the custodians as a component of validating whether the calculated contract value is an accurate approximation of fair value. The review of the general financial condition of the custodians is considered obtainable/observable through the review of readily available financial information the custodians are required to file with the SEC. The group annuity contracts are classified within Level 3 of the valuation hierarchy of ASC 820. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuations methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement. The Company expects to make contributions in 2019 of $0.4 million to the Retiree Medical Plan. The Company expects to make contributions in 2019 of between $0 and $0.5 million The following estimated benefit payments are expected to be paid in the following fiscal years: (In thousands) 2019 2020 2021 2022 2023 2024 to 2028 Pension benefits $ 74,570 $ — $ — $ — $ — $ — Post-retirement medical benefits 437 480 520 557 590 3,283 Future benefit payments of pension benefits in 2019 include routine benefit payments as well as lump sum distributions and annuitization in connection with the Plan termination. Multi-Employer Health and Welfare Plans In addition to the plans described above, the Company participates in the Michigan Conference of Teamsters and Ohio Conference of Teamsters Health and Welfare plans. The Company contributes to these multi-employer plans under the terms contained in existing CBAs and in the amounts set forth within these agreements. The health and welfare plans provide medical, dental, pharmacy, vision, and other ancillary benefits to active associates and retirees, as determined by the trustees of the plan. The Company’s contributions largely benefit active associates, and as such, may not constitute contributions to a postretirement benefit plan. However, the Company is unable to separate contribution amounts for postretirement benefits from contribution amounts paid for active participants in the plan. These plans have a significant surplus of funds held in reserve in excess of claims incurred, and there is no potential withdrawal liability related to the Company’s participation in the plans. With respect to the Company’s participation in these plans, expense is recognized as contributions are funded. The Company contributed $13.8 million, $14.1 million and $14.3 million to these plans in 2018, 2017 and 2016, respectively. Multi-Employer Pension Plan The Company also contributes to the Central States Plan, a multi-employer plan defined previously, under the terms of CBAs that cover its union-represented associates and in the amounts set forth within these agreements. The Company is party to four CBAs that require contributions to the Plan with expiration dates ranging from April 2019 to January 2022 or which the Company is in the process of negotiating and have a contemplated expiration date of February 2022. These CBAs cover warehouse personnel and drivers in Grand Rapids, Michigan and Bellefontaine and Lima, Ohio. With respect to the Company’s participation in the Central States Plan (EIN 36-60442343 / Pension Plan Number 001), expense is recognized as contributions are funded. The Company contributed $13.3 million, $13.4 million and $13.4 million to this plan in 2018, 2017 and 2016, respectively. The contributions made by the Company represent less than five percent of the Plan’s total contributions in 2018. The risk of participating in a multi-employer pension plan is different from the risk associated with single-employer plans in the following respects: a. Assets contributed to the multi-employer plan by one employer may be used to provide benefits to employees of other participating employers. b. If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. c. If a company chooses to stop participating in a multi-employer plan, makes market exits such as closing a distribution center without opening another one in the same locale, or otherwise has participation in the plan drop below certain levels, the company may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability. The PPA zone status of the Plan, which is based on information the Company received from the Plan and is certified by the Plan’s actuary, is “critical and declining” for the Plan’s two most recent fiscal years ending December 31, 2018 and 2017. Among other factors, plans in the “critical and declining” zone are generally less than 65% funded and projected to become insolvent within the next 15 years (or 20 years depending on the ratio of active-to-inactive participants). A rehabilitation plan has been implemented by the trustees of the Plan, and the CBAs that cover warehouse personnel and drivers in the Bellefontaine and Lima, Ohio distribution centers have permanent surcharges imposed due to the failure to adopt the trustee recommended rehabilitation plan. Refer to Note 9, Commitments and Contingencies, for further information regarding the Company’s participation in the Central States Plan. As of the date the consolidated financial statements were issued, Form 5500 was not available for the plan year ended December 31, 2018.

Stock-Based Compensation	Note 14 – Stock-Based Compensation The Company sponsors a shareholder-approved 10-year stock incentive plan covering 2,500,000 shares of SpartanNash’s common stock. The SpartanNash Company Stock Incentive Plan of 2015 (the “2015 Plan”) provides for the granting of stock options, stock appreciation rights, restricted stock, restricted stock units, stock awards, and other stock-based and stock-related awards to directors, officers and other key associates. Shares issued, as a result of stock option exercises, will be funded with the issuance of new shares. Holders of restricted stock and stock awards are entitled to participate in cash dividends and dividend equivalents. As of December 29, 2018, a total of 1,475,633 shares remained unissued under the 2015 Plan. All outstanding unvested stock options and unvested shares of restricted stock vest immediately upon a “Change in Control,” as defined by the Plan. The Company has not issued any stock options since 2009 and all outstanding options are vested.

Risks And Uncertainties [Abstract]
Concentration of Credit Risk	Note 15 – Concentration of Credit Risk The Company may provide financial assistance in the form of loans to certain independent retailers for inventories, store fixtures and equipment and store improvements. Loans are generally secured by liens on real estate, inventory and/or equipment, personal guarantees and other types of collateral, and are generally repayable over a period of five to ten years. The Company establishes allowances for doubtful accounts based upon periodic assessments of the credit risk of specific customers, collateral value, historical trends and other information. The Company believes that adequate provisions have been recorded for any doubtful accounts. In addition, the Company may guarantee debt and lease obligations of independent retailers. In the event these retailers are unable to meet their debt service payments or otherwise experience an event of default, the Company would be unconditionally liable for the outstanding balance of their debt and lease obligations, which would be due in accordance with the underlying agreements. In the In the ordinary course of business, the Company also subleases and assigns various leases to third parties. As of December 29, 2018, the Company estimates the present value of its maximum potential obligations for subleases and assigned leases to be approximately $5.9 million and $14.1 million, respectively.

Segment Reporting [Abstract]
Reporting Segment Information	Note 17 – Reporting Segment Information SpartanNash sells and distributes products that are typically found in supermarkets and discount stores. The operating segments reflect the manner in which the business is managed and how the Company allocates resources and assesses performance internally. The Company’s chief operating decision maker is the Chief Executive Officer, who determines the allocation of resources and, through a regular review of financial information, assesses the performance of the operating segments. The business is classified by management into three reportable segments: Food Distribution, Military and Retail. These reportable segments are three distinct businesses, each with a different customer base, management structure, and basis for determining budgets, forecasts, and executive compensation. The Company reviews its reportable segments on an annual basis, or more frequently if events or circumstances indicate a change in reportable segments has occurred. The Company’s Food Distribution segment, consisting of 14 distribution centers as well as facilities to process fresh produce, proteins, and meal kits, supplies grocery products, including dry groceries, produce, dairy products, meat, delicatessen items, bakery goods, frozen food, seafood, floral products, general merchandise, beverages, tobacco products, health and beauty care products and pharmacy primarily to a diverse group of independent and chain retailers, food service distributors and the Company’s corporate owned retail stores. The Company also offers certain value-added services (e.g., accounting, payroll, marketing, etc.) to its independent retail customers. These services are not material to the Company’s financial statements. Sales to independent retailers and inter-segment sales are recorded based upon both a “cost plus” model and a “variable mark-up” model, which vary by commodity and servicing distribution center. The Military segment contracts with manufacturers and brokers to distribute a wide variety of grocery products, including dry groceries, beverages, meat, and frozen foods, primarily to U.S. military commissaries and exchanges from its 7 distribution centers, two of which are shared with the Food Distribution segment. The contracts typically specify the commissaries and exchanges to supply on behalf of the manufacturer, the manufacturer’s products to be supplied, service and delivery requirements and pricing and payment terms. The Company is also the DeCA exclusive worldwide supplier of private brand grocery and related products to U.S. military commissaries. The Company procures the grocery and related products from various manufacturers, and upon receiving customer orders from DeCA, either delivers the products to the U.S. military commissaries itself or partners with Coastal Pacific Food Distributor The Retail segment operated 139 corporate owned retail stores and 29 fuel centers, predominantly in the Midwest region, as of December 29, 2018. The Company’s retail stores typically offer dry groceries, produce, dairy products, meat, delicatessen items, bakery goods, frozen food, seafood, floral products, general merchandise, beverages, tobacco products and health and beauty care products. The Company also offered pharmacy services in 83 of its corporate owned retail stores as of December 29, 2018.

Subsequent Events	Note 19 – Subsequent Events On December 31, 2018, the Company acquired all of the equity of Martin’s Super Markets (“Martin’s”) for $84.3 million, net of cash acquired. The purchase price is subject to customary working capital adjustments, as necessary. Founded in 1947 and headquartered in South Bend, Indiana, Martin’s currently operates 21 stores in Northern Indiana and Southwest Michigan with approximately 3,500 employees. For their fiscal year ended July 29, 2018, Martin’s had more than $450 million in net sales. Martin’s was an independent retailer and customer of the Company’s Food Distribution segment as of December 29, 2018, and sales from the Food Distribution segment to Martin’s will be eliminated going forward. The acquisition will expand the footprint of the Company’s Retail segment into northern Indiana and southwestern Michigan. The acquisition was funded with proceeds from the Company’s Credit Agreement (Note 7).

Summary of Significant Accoun_2

Summary of Significant Accounting Policies and Basis of Presentation (Policies)	12 Months Ended
	Dec. 29, 2018
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation: The consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of SpartanNash Company and its subsidiaries (“SpartanNash” or “the Company”). Intercompany accounts and transactions have been eliminated.
Fiscal Year	Fiscal Year: The Company’s fiscal year end is the Saturday nearest to December 31. The following discussion is as of and for the fiscal years ending or ended December 28, 2019 (“2019”), December 29, 2018 ("2018" or “current year”), December 30, 2017 (“2017” or “prior year”) and December 31, 2016 (“2016”), all of which include 52 weeks. All fiscal quarters are 12 weeks, except for the Company’s first quarter, which is 16 weeks.
Use of Estimates	Use of Estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported therein. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods might differ from those estimates.
Revenue Recognition	Revenue Recognition: The Company recognizes revenue when it satisfies a performance obligation by transferring control of the promised goods and services to a customer, in an amount that reflects the consideration that it expects to receive in exchange for those goods or services. This is achieved through applying the following five-step model: • Identification of the contract, or contracts, with a customer • Identification of the performance obligations in the contract • Determination of the transaction price • Allocation of the transaction price to the performance obligations in the contract • Recognition of revenue when, or as, the Company satisfies a performance obligation The Company generates substantially all of its revenue from contracts with customers, whether formal or implied. Sales taxes collected from customers are remitted to the appropriate taxing jurisdictions and are excluded from sales revenue as the Company considers itself a pass-through conduit for collecting and remitting sales taxes, with the exception of taxes assessed during the procurement process of select inventories. Greater than 99% of the Company’s revenues are recognized at a point in time. Revenues from product sales are recognized when control of the goods is transferred to the customer, which occurs at a point in time, typically upon delivery or shipment to the customer, depending on shipping terms, or upon customer check-out in a corporate owned retail store. Freight revenues are also recognized upon delivery, at a point in time. Other revenues, including revenues from value-added services, are recognized as earned, over a period of time. All of the Company’s revenues are domestic, as the Company has no performance obligations on international shipments subsequent to delivery to the domestic port. The Company evaluates whether it is the principal (i.e., report revenues on a gross basis) or agent (i.e., report revenues on a net basis) with respect to each contract with customers. Based upon the nature of the products the Company sells, its customers have limited rights of return which are immaterial. Discounts provided by the Company to customers at the time of sale are recognized as a reduction in sales as the products are sold. Certain contracts include rebates and other forms of variable consideration, including up-front rebates, rebates in arrears, rebatable incentives, flex funds, and product incentives, which may have tiered structures based on purchase volumes and which are accounted for as variable consideration. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur.
Cost of Sales	Cost of Sales: Cost of sales represents the cost of inventory sold during the period, which for all non-production operations includes purchase costs, in-bound freight, physical inventory adjustments, markdowns and promotional allowances and excludes warehousing costs, depreciation and other administrative expenses. For the Company’s food processing operations, cost of sales includes direct product and production costs, inbound freight, purchasing and receiving costs, utilities, depreciation, and other indirect production costs and excludes out-bound freight and other administrative expenses. As a result, the Company’s cost of sales and gross profit may not be identical to similarly titled measures reported by other companies. Vendor allowances and credits that relate to the Company’s buying and merchandising activities consist primarily of promotional allowances, which are generally allowances on purchased quantities and, to a lesser extent, slotting allowances, which are billed to vendors for the Company’s merchandising costs such as setting up warehouse infrastructure. Vendor allowances are recognized as a reduction in cost of sales when the related product is sold. Lump sum payments received for multi-year contracts are amortized over the life of the contracts based on contractual terms. The distribution segments include shipping and handling costs in the selling, general and administrative section of operating expenses on the consolidated statement of operations.
Cash and Cash Equivalents	Cash and Cash Equivalents: Cash and cash equivalents consist of cash and highly liquid investments with an original maturity of three months or less at the date of purchase.
Accounts and Notes Receivable	Accounts and Notes Receivable: Accounts and notes receivable are shown net of allowances for credit losses of $4.3 million and $2.0 million as of December 29, 2018 and December 30, 2017, respectively. The Company evaluates the adequacy of its allowances by analyzing the aging of receivables, customer financial condition, historical collection experience, the value of collateral and other economic and industry factors. Actual collections may differ from historical experience, and if economic, business or customer conditions deteriorate significantly, adjustments to these reserves may be required. When the Company becomes aware of factors that indicate a change in a specific customer’s ability to meet its financial obligations, the Company records a specific reserve for credit losses. Operating results include bad debt expense of $3.4 million, $1.5 million and $1.4 million for 2018, 2017 and 2016, respectively.
Inventory Valuation	Inventory Valuation: Inventories are valued at the lower of cost or market. Approximately 88.9% and 86.9% of the Company’s inventories were valued on the last-in, first-out (LIFO) method at December 29, 2018 and December 30, 2017, respectively. If replacement cost had been used, inventories would have been $55.1 million and $50.4 million higher at December 29, 2018 and December 30, 2017, respectively. The replacement cost method utilizes the most current unit purchase cost to calculate the value of inventories. During 2018, 2017 and 2016, certain inventory quantities were reduced. The reductions resulted in liquidation of LIFO inventory carried at lower costs prevailing in prior years, the effect of which decreased the LIFO provision in 2018 by $1.1 million, and in 2017 and 2016 by $0.2 million. The Company accounts for its Food Distribution and Military inventory using a perpetual system and utilizes the retail inventory method (“RIM”) to value inventory for center store products in the Retail segment. Under RIM, inventory is stated at cost with cost of sales and gross margin calculated by applying a cost ratio to the retail value of inventories. Fresh, pharmacy and fuel products are accounted for at cost in the Retail segment. The Company evaluates inventory shortages throughout the year based on actual physical counts in its facilities. The Company records allowances for inventory shortages based on the results of recent physical counts to provide for estimated shortages from the last physical count to the financial statement date.
Goodwill and Intangible Assets	Goodwill and Intangible Assets: Goodwill represents the excess purchase price over the fair value of tangible net assets acquired in business combinations after amounts have been allocated to intangible assets. Goodwill is not amortized, but is reviewed for impairment during the last quarter of each year, or whenever events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount, using a discounted cash flow model and comparable market values of each reporting segment. Measuring the fair value of reporting units is a Level 3 measurement under the fair value hierarchy. See Note 8, Fair Value Measurements, for a discussion of levels. Intangible assets primarily consist of trade names, customer relationships, favorable lease agreements, pharmacy prescription lists, non-compete agreements, liquor licenses and franchise fees. The following assets are amortized on a straight-line basis over the period of time in which their expected benefits will be realized: favorable leases (related lease terms), prescription lists and customer relationships (period of expected benefit reflecting the pattern in which the economic benefits are consumed), non-compete agreements and franchise fees (length of agreements), and trade names with definite lives (expected life of the assets). Indefinite-lived trade names are not amortized but are tested at least annually for impairment, and liquor licenses are also not amortized as they have indefinite lives. Intangible assets are included in “Other Assets, net” in the consolidated balance sheets.
Property and Equipment	Property and Equipment: Property and equipment are recorded at cost. Expenditures which improve or extend the life of the respective assets are capitalized, whereas expenditures for normal repairs and maintenance are charged to operations as incurred. Depreciation expense on land improvements, buildings and improvements, and equipment is computed using the straight-line method as follows: Land improvements 15 years Buildings and improvements 15 to 40 years Equipment 3 to 15 years Property under capital leases and leasehold improvements are amortized on a straight-line basis over the shorter of the remaining terms of the leases or the estimated useful lives of the assets. Internal use software is included in property and equipment and amounted to $33.5 million and $30.7 million as of December 29, 2018 and December 30, 2017, respectively.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets: The Company reviews and evaluates long-lived assets for impairment when events or circumstances indicate that the carrying amount of an asset may not be recoverable. When the undiscounted expected future cash flows are not sufficient to recover an asset’s carrying amount, the fair value is compared to the carrying value to determine the impairment loss to be recorded. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value, less the cost to sell. Fair values are determined by independent appraisals or expected sales prices based upon market participant data developed by third party professionals or by internal licensed real estate professionals. Estimates of future cash flows and expected sales prices are judgments based upon the Company’s experience and knowledge of operations. These estimates project cash flows several years into the future and are affected by changes in the economy, real estate market conditions and inflation.
Reserves for Closed Properties	Reserves for Closed Properties: The Company records reserves for closed properties that are subject to long-term lease commitments based upon the future minimum lease payments and related ancillary costs from the date of closure to the end of the remaining lease term, net of estimated sublease rentals that could be reasonably expected to be obtained for the property. Future cash flows are based on contractual lease terms and knowledge of the geographic area in which the closed site is located. These estimates are subject to multiple factors, including inflation, ability to sublease the property and other economic conditions. Internally developed estimates of sublease rentals are based upon the geographic areas in which the properties are located, the results of previous efforts to sublease similar properties, and the current economic environment. The reserved expenses are paid over the remaining lease terms, which range from one to 10 years. Adjustments to closed property reserves primarily relate to changes in subtenant income or actual exit costs differing from original estimates. Adjustments are made for changes in estimates in the period in which the changes become known. The current portion of the future lease obligations of stores is included in “Other accrued expenses,” and the long-term portion is included in “Other long-term liabilities” in the consolidated balance sheets.
Debt Issuance Costs	Debt Issuance Costs : Debt issuance costs are amortized over the term of the related financing agreement and are included as a direct deduction from the carrying amount of the related debt liability in “Long-term debt and capital lease obligations” in the consolidated balance sheets.
Insurance Reserves	Insurance Reserves: SpartanNash is self-insured through self-insurance retentions or high deductible programs for workers’ compensation, general liability, and automobile liability, and is also self-insured for healthcare costs. Self-insurance liabilities are recorded based on claims filed and an estimate of claims incurred but not yet reported. Workers’ compensation, general liability and automobile liabilities are actuarially estimated based on available historical information on an undiscounted basis. The Company has purchased stop-loss coverage to limit its exposure to any significant exposure on a per claim basis for its self-insurance retentions and high deductible programs. On a per claim basis, the Company’s exposure is up to $0.5 million for workers’ compensation and general liability, $1.0 million for automobile liability and $0.5 million for healthcare per covered life per year. A summary of changes in the Company’s self-insurance liability is as follows: (In thousands) 2018 2017 2016 Balance at beginning of year $ 15,155 $ 14,730 $ 14,466 Expenses 49,532 54,748 49,560 Claim payments, net of employee contributions (50,396 ) (54,323 ) (49,296 ) Balance at end of year $ 14,291 $ 15,155 $ 14,730 The current portion of the self-insurance liability was $8.6 million and $8.7 million as of December 29, 2018 and December 30, 2017, respectively, and is included in “Other accrued expenses” in the consolidated balance sheets. The long-term portion was $5.7 million and $6.5 million as of December 29, 2018 and December 30, 2017, respectively, and is included in “Other long-term liabilities” in the consolidated balance sheets.
Income Taxes	Income Taxes: Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future. Such deferred income tax asset and liability computations are based on enacted tax laws and rates applicable to periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized. Income tax expense is the tax payable or refundable for the period plus or minus the change during the period in deferred and other tax assets and liabilities.
Earnings per share	Earnings per share: Earnings per share (“EPS”) is computed using the two-class method. The two-class method determines EPS for each class of common stock and participating securities according to dividends and their respective participation rights in undistributed earnings. Participating securities include non-vested shares of restricted stock in which the participants have non-forfeitable rights to dividends during the performance period. Diluted EPS includes the effects of stock options. The following table sets forth the computation of basic and diluted EPS for continuing operations: (In thousands, except per share amounts) 2018 2017 2016 Numerator: Earnings (loss) from continuing operations $ 33,791 $ (52,617 ) $ 57,056 Adjustment for (earnings) loss attributable to participating securities (746 ) 908 (1,011 ) Earnings (loss) from continuing operations used in calculating earnings per share $ 33,045 $ (51,709 ) $ 56,045 Denominator: Weighted average shares outstanding, including participating securities 36,012 37,419 37,483 Adjustment for participating securities (795 ) (646 ) (664 ) Shares used in calculating basic earnings per share 35,217 36,773 36,819 Effect of dilutive stock options 10 — 73 Shares used in calculating diluted earnings per share 35,227 36,773 36,892 Basic earnings (loss) per share from continuing operations $ 0.94 $ (1.41 ) $ 1.52 Diluted earnings (loss) per share from continuing operations $ 0.94 $ (1.41 ) $ 1.52 Weighted average shares issuable upon the exercise of stock options that were not included in the EPS calculations because they were anti-dilutive were 75,159 for 2017. There were no anti-dilutive stock options in 2018 or 2016.
Stock-Based Compensation	Stock-Based Compensation: All share-based payments to associates are recognized in the consolidated financial statements as compensation cost based on the fair value on the date of grant. The grant date closing price per share of SpartanNash stock is used to estimate the fair value of restricted stock awards and restricted stock units. The value of the portion of awards expected to vest is recognized as expense over the requisite service period.
Shareholders' Equity	Shareholders’ Equity: The Company’s restated articles of incorporation provide that the Board of Directors may at any time, and from time to time, provide for the issuance of up to 10 million shares of preferred stock in one or more series, each with such designations as determined by the Board of Directors. At December 29, 2018 and December 30, 2017, there were no shares of preferred stock outstanding.
Advertising Costs	Advertising Costs: The Company’s advertising costs are expensed as incurred and are included in Selling, general and administrative expenses. Advertising expenses were $40.9 million, $43.4 million and $46.6 million in 2018, 2017 and 2016, respectively.
Accumulated Other Comprehensive Income (Loss)	Accumulated Other Comprehensive Income (Loss)(“AOCI”): The Company reports comprehensive income (loss) that includes net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) refers to expenses, gains and losses that are not included in net earnings, such as pension and other postretirement liability adjustments, but rather are recorded directly to shareholders’ equity. These amounts are also presented in the consolidated statements of comprehensive income. As of December 29, 2018 and December 30, 2017, AOCI relates to the pension and postretirement plans.
Discontinued operations	Discontinued operations: Certain of the Company’s Food Distribution and Retail operations have been recorded as discontinued operations. Results of discontinued operations are excluded from the accompanying notes to the consolidated financial statements for all periods presented, unless otherwise noted. Results of discontinued operations reported on the consolidated statements of operations are reported net of tax.
Adoption of New Accounting Standards and Recently Issued Accounting Standards	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers – Topic 606” (“ASC 606”). The new guidance affects any reporting organization that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. As of the beginning of 2018, the Company adopted ASC 606 and all subsequent ASUs that modified ASC 606. Refer to Note 3, Revenue Recognition, for additional information about adoption of this guidance and additional disclosures required under the standard. From a principal versus agent perspective, the Company determined that certain contracts in the Food Distribution segment that were historically reported on a gross basis are now required to be reported on a net basis, resulting in a corresponding decrease to both net sales and cost of sales of $177.1 million in 2018 from what would have been recognized under previous guidance. The implementation of the guidance had no impact on gross profit, net earnings, the balance sheet, cash flows, equity, or the timing of revenue recognition in current or prior periods. The adoption of the guidance using the full retrospective method resulted in decreases to fiscal 2017 and 2016 net sales and cost of sales previously reported as shown in the following table: Full Year 4th Quarter 3rd Quarter 2nd Quarter 1st Quarter (In thousands) (52 Weeks) (12 Weeks) (12 Weeks) (12 Weeks) (16 Weeks) 2017 $ 164,283 $ 38,725 $ 38,246 $ 38,510 $ 48,802 2016 $ 173,516 $ 43,168 $ 42,382 $ 38,594 $ 49,372 In March 2017, the FASB issued ASU 2017-07, “Compensation – Retirement Benefits.” ASU 2017-07 requires that the service cost component of pension and postretirement benefit costs be presented in the same line item as other current employee compensation costs and other components of those benefit costs be presented separately from the service cost component and outside a subtotal of income from operations, if presented. The ASU also requires that only the service cost component of pension and postretirement benefit costs is eligible for capitalization. The Company adopted this guidance as of the beginning of 2018. Accordingly, benefit costs other than service cost, are reflected in the condensed consolidated statements of earnings in Other, net, whereas they previously were recognized in Selling, general and administrative expenses. Retrospective application resulted in a decrease to Other, net and an increase in Selling, general and administrative expenses. The costs associated with the reclassifications were not material in any of the periods presented. In August 2018, the FASB issued ASU 2018-15, “Intangibles – Goodwill and Other – Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract” in order to provide additional guidance on the accounting for costs of implementation activities performed in a cloud computing arrangement that is a service contract. This is an amendment to ASU 2015-05, “Intangibles—Goodwill and Other—Internal-Use Software: Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company early adopted this guidance retrospectively as of the beginning of fiscal 2018, as permitted by the amendment. The adoption of this guidance did not have a significant effect on the Company’s financial statements. In August 2018, the FASB issued ASU 2018-14, “Compensation—Retirement Benefits—Defined Benefit Plans—General: Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans.” The amendments in this ASU remove disclosures that are no longer considered to be cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The amendments in ASU 2018-14 are effective for fiscal years ending after December 15, 2020 and will be applied on a retrospective basis to all periods presented. The adoption of this guidance is not expected to have a significant effect on the Company’s financial statements. In January 2017, the FASB issued ASU 2017-01, “Business Combinations – Clarifying the Definition of a Business.” ASU 2017-01 narrows the definition of a business and provides a screen to determine when a set of the three elements of a business – inputs, processes, and outputs – are not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. If the screen is not met, the amendments (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The amendments provide a framework to assist entities in evaluating whether both an input and a substantive process are present. The guidance was effective for the Company as of the beginning of 2018. As no business combinations have occurred in 2018, there has been no impact on the consolidated financial statements for the current year. The adoption has no impact on the Company’s historical financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases.” The FASB subsequently issued ASU’s 2018-01, 2018-10, and 2018-11, which include clarifications and provide various practical expedients and transition options related to ASU 2016-02. ASU 2016-02 provides guidance for lease accounting and stipulates that lessees will need to recognize a right-of-use asset and a lease liability for substantially all leases (other than leases that meet the definition of a short-term lease). The liability will be equal to the present value of lease rent payments. Treatment in the consolidated statements of operations will be similar to the current treatment of operating and capital leases. The Company adopted the standard as of December 30, 2018, the beginning of fiscal 2019. The Company has elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allows for the carryforward of the historical lease classification. In addition, the Company has elected the hindsight practical expedient to reassess the reasonably certain lease term for existing leases. The election of the hindsight practical expedient will result in the extension or reduction of lease terms for certain existing leases, and adjustments to the useful lives of corresponding leasehold improvements. The Company will make an accounting policy election not to record lease liabilities or right of use assets for short-term leases, those with an initial minimum term of less than one year. The adoption of the standard will result in a recognition of additional lease assets and lease liabilities of approximately $240 million and $290 million, respectively, as of December 30, 2018, and a transition adjustment recorded to beginning of the year retained earnings of approximately $27 million (net of deferred tax impact of $9 million). The transition adjustment relates to impairment of right of use assets in transition and the impact of hindsight on the evaluation of lease term. Remaining differences between lease assets and liabilities relate to the derecognition of existing lease-related liabilities and assets recorded under ASC 840, which were included in beginning lease liabilities under ASC 842. The Company does not believe the new standard will have an impact on liquidity or on debt-covenant compliance under the current agreements.
