Notes to Financial Statements |
Earnings Per Share [Text Block] | 14. Net Loss per Common Share Basic income (loss) per common share is calculated by dividing the net income (loss) available to the common shareholders by the weighted average number of common shares outstanding during that period. Diluted net loss per share reflects the potential of securities that could share in the net loss of the Company. For each three -month period presented, the basic and diluted loss per share were the same for 2020 and 2019, as they were not included in the calculation of the diluted net loss per share because they would have been anti-dilutive. The following table sets-forth securities that could be potentially dilutive, but as of the three and six -months ended December 31, 2020 and 2019 are anti-dilutive, and therefore excluded from the calculation of diluted earnings per share.
