Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 8 – Commitments and Contingencies 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 may advance funds to 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. The Company had previously advanced funds to one independent retailer who subsequently defaulted on the terms of the supply agreement and went into receivership. To realize its collateral, the Company obtained the rights to acquire five stores, of which the rights related to three of the stores were assigned to an independent retailer in exchange for certain consideration as part of a long-term supply agreement and the Company acquired the two remaining stores. Both the execution of the long-term supply agreement and the acquisition of two stores occurred during the second quarter of 2019. The excess of the purchase price over the fair value of net assets acquired of $2.4 million was recorded as goodwill in the consolidated balance sheet and allocated to the Food Distribution segment based on the relative value of the assets acquired and the expected cash flows between the Retail and Food Distribution segments. The Company contributes to the Central States Southeast and Southwest Pension Fund (“Central States Plan” or “the Plan”), a multi-employer pension plan, based on obligations arising from its collective bargaining agreements (“CBAs”) in Bellefontaine, Ohio, Lima, Ohio, and Grand Rapids, Michigan covering its supply chain associates at those locations. 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. 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 and the administration of the plan. The Company currently contributes to the Central States 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 set within the CBAs 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% funded and are projected to become insolvent within the next 15 years (or 20 years depending on the ratio of active-to-inactive participants). 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 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.
