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 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 28, 2019. 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.
