[1] We discovered immaterial errors in prior years relating to the accuracy of certain tax accounts. While we concluded that the impact of these errors on our previously-issued consolidated financial statements was not material, we revised our previously-reported consolidated financial statements for the fiscal years ended June 29, 2016 and June 24, 2015. The revisions to the consolidated statements of shareholder's (deficit) equity include a $10.3 million decrease to retained earnings at the beginning of fiscal 2015 and decreases to net income of $2.1 million and $0.1 million for fiscal 2015 and fiscal 2016, respectively, for a total reduction of $12.5 million.
