Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 9 – Commitments and Contingencies The Company continuously evaluates its exposure to loss contingencies, including those related to routine legal proceedings to which the Company is a party and which are incidental to its business, based upon the best available information. Although assessing and predicting the outcome and impact related to loss contingencies involves substantial uncertainties, the Company believes that its allowances for loss have been disclosed to the extent necessary, that its assessment of contingencies is reasonable and that their outcome will not result in a material adverse effect on the Company’s consolidated financial position, operating results or liquidity. Any material variations in or adjustments to the Company's loss contingency estimates will be reported when known. The Company has contributed and is required to continue making contributions to the Central States Southeast and Southwest Pension Fund (the “Central States Plan” or the “Plan”), a multi-employer pension plan, based on obligations arising from certain of its collective bargaining agreements. If the Company were to cease making such contributions and triggered a withdrawal from the Plan, it is possible that the Company would be obligated to pay a withdrawal liability to the Plan if the Plan is underfunded at the time of such withdrawal. On January 12, 2023, the Central States Plan received approximately $35.8 billion in Special Financial Assistance (the "SFA") from the Pension Benefit Guaranty Corporation, inclusive of interest, which was granted to alleviate the risk of insolvency of the Plan. On March 29, 2024, in accordance with the Pension Protection Act ("PPA"), the Plan's actuary certified that the Plan was considered to be in "critical" zone status for the plan year beginning January 1, 2024. In light of the receipt of the SFA, the Central States Plan has represented that the Plan is expected to be funded well into the future. Despite the expectations of the Plan, the Company views the Plan's solvency as an ongoing risk factor. Based on the most recent information available to the Company, management believes the value of assets held in trust to pay benefits covers the present value of actuarial accrued liabilities in the Central States Plan. Management is not aware of any significant change in funding levels in the Plan since December 28, 2024. Due to uncertainty regarding future factors that could trigger a withdrawal liability or increase the funding obligations of the Plan borne by the Company, as well as the absence of specific information regarding matters such as the Plan's current financial situation, we are unable to determine with certainty the current amount of the Plan’s funding, SpartanNash’s current potential withdrawal liability exposure in the event of a future withdrawal from the Plan and/or the Company's potential exposure to increased funding obligations in the event of one or more participating employers withdrawing from the Plan. Any adjustment for withdrawal liability would be recorded when it is probable that a liability exists and can be reasonably determined.
