Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. These statements should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended December 29, 2012.

All share and per-share information in the Quarterly Report on Form 10-Q has been retroactively restated to reflect the stock split.
