The results of operations for the three months ended March 1, 2014 are not necessarily indicative of results for the full fiscal year. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended November 30, 2013. We calculate an anticipated effective tax rate for the year based on our annual estimates of pretax income or loss and use that effective tax rate to record our year-to-date income tax provision. Any change in annual projections of pretax income or loss could have a significant impact on our effective tax rate for the respective quarter. Our effective tax rates for the quarters ended March 1, 2014 and March 2, 2013 differ from the federal statutory rate primarily due to the effects of state income taxes and permanent differences resulting from non-deductible expenses.
