Earnings Per Share [Abstract] |
Earnings per share | Earnings per share The Company calculates earnings per share in accordance with FASB guidance on earnings per share. Basic and diluted earnings per common share give effect to the change in the number of Company common shares outstanding. The calculation of basic earnings per common share is determined by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the respective periods. The potentially dilutive shares, consisting of outstanding options on common shares, restricted share units, common shares to be issued under the ESPP and performance units, have been included in the computation of diluted net earnings per share and the number of weighted average shares outstanding, except where the result would be anti-dilutive. The number of stock awards outstanding but not included in the computation of diluted earnings per common share because their effect was anti-dilutive is 1,809,069, 1,182,572 and 1,663,219 for the years ended December 31, 2019, 2020 and 2021, respectively.
