[1] We define gross profit as revenue less cost of goods sold, payroll and related costs, and other restaurant operating costs.

[2] The sum of the quarterly (loss)/income 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.
