[1] The first quarter encompasses the typical start of school and second quarter includes Christmas and Thanksgiving holidays.

[2] In the second quarter of fiscal 2014, we identified and corrected immaterial accounting errors in prepaid assets and payroll related liabilities. The Company did not expense amounts related to these accounts properly in the appropriate prior periods. The errors impacted all prior reporting periods beginning in 2007. Based on management's analysis of the error as required by guidance in ASC 250-10 relating to SEC Staff Accounting Bulletin ("SAB") Topic1.M, Assessing Materiality and SAB Topic 1.N, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, Income from continuing operations for quarter one of fiscal year 2014 and quarters one through four of fiscal year 2013 have been revised. See Note 1. Nature of Operations and Significant Accounting Policies. In addition, Restaurant sales, Income from continuing operations and Discontinued operations were revised to reflect the Company's disposal plans discussed in Note 8.
