Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per Share Basic earnings per share is based on the weighted average number of common shares outstanding during the year. Diluted earnings per share reflects the assumed exercise of outstanding options and the conversion of restricted stock units ("RSUs") under the Company's various stock compensation plans, except when RSUs and options have an antidilutive effect. There were 128,701 and 118,696 antidilutive RSUs and options outstanding at July 31, 2021 and July 31, 2020, respectively. The following is a reconciliation of basic to diluted weighted average common shares outstanding (in thousands):
