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 will be amortized over fifteen years, and indefinite lived trade names. In connection with the purchase, the Company is providing 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. If certain performance targets are 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, if applicable, 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 after the third-year anniversary of the acquisition date. The acquisition was funded with proceeds from the Company’s Credit Agreement. As of December 30, 2017, the Company has incurred $4.9 million of total acquisition-related costs associated with the transaction, of which $2.7 million was incurred in 2017 and is recorded in merger/acquisition and integration expense. Founded in Indianapolis in 1965, Caito is a leading supplier of fresh fruits and vegetables as well as value-added meal solutions to grocery retailers and food service distributors across 21 states in the Southeast, Midwest and Eastern United States. BRT offers temperature-controlled distribution and logistics services throughout North America. Caito and BRT service customers from facilities in Indiana and Florida. Caito also has a fresh-cut fruit and vegetable facility in Indianapolis and a new 118,000 square foot Fresh Kitchen facility, also in Indianapolis. The Fresh Kitchen provides the Company with the ability to process, cook, and package fresh protein-based foods and complete meal solutions. The Company has begun production in the Fresh Kitchen facility and is in the process of ramping up to full production. The Company acquired Caito and BRT to strengthen its fresh product offerings to its existing customer base and to expand into fast-growing, value-added services, such as freshly-prepared centerplate and side dish categories. The acquired assets and assumed liabilities were recorded at their estimated fair values based on appraised value and discounted cash flow analyses as of the acquisition date, based on preliminary estimates, and have since been finalized. The Company increased goodwill by $1.3 million as a result of certain measurement period adjustments primarily associated with updated valuations of certain acquired long-lived assets. The excess of the purchase price over the fair value of net assets acquired of $46.3 million was recorded as goodwill in the consolidated balance sheet and allocated to the Food Distribution segment. The goodwill recognized is attributable primarily to the assembled workforce of Caito and BRT and expected synergies. The Company expects that all goodwill attributable to the acquisition will be deductible for tax purposes. On June 16, 2015, the Company acquired certain assets and assumed certain liabilities of Dan’s Super Market, Inc. (Dan’s) for a total purchase price of $32.6 million. Dan’s was a six-store chain serving Bismarck and Mandan, North Dakota, and was not a customer of the SpartanNash Food Distribution segment prior to the acquisition. The Company acquired the Dan’s stores to strengthen its offering in this region from both a retail and distribution perspective. During the measurement period, which ended June 15, 2016, there were no material adjustments made to the initial fair values of the assets acquired and liabilities assumed as part of the Dan’s acquisition.
