[1] The sum of the quarterly loss per share does not equal the reported annual amount as each is computed independently based upon the weighted average number of shares outstanding for the period.

[2] We define gross profit as revenue less cost of goods sold, payroll and related costs, and other restaurant operating costs. As previously discussed in Note 1 to the Consolidated Financial Statements, we reclassified amortization of intangible assets from other restaurant operating costs to depreciation and amortization in the Consolidated Statements of Operations and Comprehensive Loss for the prior fiscal year to be comparable with the classification for the fiscal year ended June 6, 2017.
