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.  There were no awards excluded from the computation of diluted earnings per share for the quarter ended March 31, 2018, and approximately 579 thousand stock-based awards excluded from the computation of diluted earnings per share for the quarter ended April 1, 2017 because they were antidilutive.
