Amendment Description	The Nash-Finch Company is filing this Amendment No. 1 (the "Form 10-Q/A") to our Quarterly Report on Form 10-Q for the quarter ended March 23, 2013 (the "Form 10-Q"), filed with the Securities and Exchange Commission ("SEC") on April 25, 2013, solely to disclose certain corrections were made to Note 10 – Segment Reporting of the financial statements furnished in Part I, Item I. The Reconciliation to Consolidated Statements of Income table inadvertently omitted information in the Year-to-Date Ended March 23, 2013 column from the Form 10-Q as originally filed due to unanticipated technical difficulties. No other changes have been made to the Form 10-Q. This Form 10-Q/A continues to speak as of the original filing date of the Form 10-Q, does not reflect events that may have occurred subsequent to the original filing date, and does not modify or update any related disclosures made in the Form 10-Q.
