Potentially dilutive securities attributable to outstanding stock options and restricted stock units were excluded from the calculation of diluted earnings per share where the combined exercise price and average unamortized fair value were greater than the average market price of the Company's Class A Nonvoting Common Stock because the effect would have been anti-dilutive. The amount of anti-dilutive shares were 471,377 and 829,617 for the three months ended January 31, 2022 and 2021, respectively, and 475,489 and 785,181 for the six months ended January 31, 2022 and 2021, respectively.
