[1] Options to purchase 1,945,348 common shares and 1,364,013 common shares for the three months ended March 31, 2018 and 2017, respectively, and options to purchase 3,086,121 common shares and 1,391,300 common shares for the nine months ended March 31, 2018 and 2017, respectively were not included in the computation of the three month and nine month period for diluted earnings per share, respectively, because the exercise price was greater than the average fair market value of the common shares. For the three months ended in March 31, 2017 and nine months ended March 31, 2018, the effect of dilutive securities was not included in the calculation of diluted earnings (loss) per share because there was a net operating loss for the period.
