For fiscal 2018, 0.1 million options were excluded from the calculation of dilutive potential common shares. For fiscal 2019 and 2017, no options were excluded from the calculation of dilutive potential common shares. These options were not included in the computation of dilutive potential common shares because the assumed proceeds per share exceeded the average market price per share for that period. Therefore, their inclusion would have been anti-dilutive.
