Earnings Per Share [Abstract]

Earnings per Common Share

Earnings per Common Share

Basic per share amounts have been computed based on the average number of common shares outstanding.  Diluted per share amounts reflect the increase in average common shares outstanding that would result from the assumed exercise of outstanding stock options and vesting of restricted stock awards, computed using the treasury stock method.  Approximately 52 thousand and 218 thousand stock-based awards were excluded from the computation of diluted earnings per share for the quarters ended September 30, 2017 and October 1, 2016, respectively, because they were antidilutive.
