[1] During fiscal 2013, the Company disaggregated its previous reportable segment, Retail Food, into two separate reportable segments: Retail Food and Save-A-Lot (formerly referred to the Hard Discount operating segment within the Retail Food reportable segment) and previously reported segment information has been revised to conform to current presentation. These changes do not revise or restate information previously reported in the Consolidated Statements of Operations, Consolidated Statements of Comprehensive Loss, Consolidated Balance Sheets, Consolidated Statements of Stockholders' Equity or Consolidated Statements of Cash Flows for the Company for any period. Refer to Note 14-Segment Information in the accompanying Notes to Consolidated Financial Statements for additional information concerning the Company's reportable segments. During the first quarter of fiscal 2014, the Company reclassified the segment presentation of certain corporate administrative expenses and related fees earned under the Company's Transition Services Agreements, pension and other postretirement plan expenses for inactive and corporate participants in the SUPERVALU Retirement Plan and certain other corporate costs to properly reflect the structure under which the Company is now being managed. These changes primarily resulted in the recast of net expenses from the Company's Retail Food segment and Independent Business segments to its Corporate and Save-A-Lot segments for all periods presented and as previously reported in the Company's Annual Report on Form 10-K for the year ended February 23, 2013. These changes do not revise or restate information previously reported in the Consolidated Statements of Operations, Consolidated Statements of Comprehensive Loss, Consolidated Balance Sheets, Consolidated Statements of Stockholders' Equity or Consolidated Statements of Cash Flows for the Company for any annual period.
