*Prior period information has been restated for the adoption of ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” which we adopted on October 1, 2018.

For the three months ended June 30, 2019 and 2018, there were 617,841 and 770,178 potentially dilutive shares, respectively, and for the nine months ended June 30, 2019 and 2018, there were 667,841 and 977,828 potentially dilutive shares, respectively, related to stock options to purchase common shares that were not included in the above computation of diluted earnings per common share since the options’ exercise prices were greater than the average market price of our common shares. In addition, due to the net loss for the nine months ended June 30, 2018, there were 440,002 common stock options and restricted stock units that were not included in the above computation of diluted earnings per share.
