For the three months ended October 31, 2020 and 2019, approximately 1.0 million and 3.2 million shares, respectively, attributable to stock options and restricted stock units were excluded from the calculation of diluted earnings per share as their inclusion would have been anti-dilutive.

For the nine months ended October 31, 2020 and 2019, approximately 0.6 million and 0.3 million shares, respectively, attributable to stock options and restricted stock units were excluded from the calculation of diluted earnings per share as their inclusion would have been anti-dilutive.
