Earnings Per Share [Abstract] |
Earnings Per Share | (9) Earnings Per Share Basic earnings per share was computed by dividing net income by the weighted-average number of Common Shares outstanding for each respective period. Diluted earnings per share was calculated by dividing net income by the weighted-average of all potentially dilutive Common Shares that were outstanding during the periods presented. However, for all periods in which the Company recognized a net loss, the Company did not recognize the effect of the potential dilutive securities as their inclusion would be anti-dilutive. Potential dilutive shares of 239,254 for the three months ended September 30, 2021 were excluded from diluted loss per share because the effect would be anti-dilutive. Potential dilutive shares of 265,335 for the nine months ended September 30, 2020 were excluded from diluted loss per share because the effect would be anti-dilutive. Weighted-average Common Shares outstanding used in calculating basic and diluted earnings per share were as follows:
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Three months ended | ​ | Nine months ended | ​ | ​
​ | ​ | September 30, | ​ | September 30, | ​ | ​
​ |  | 2021 |  | 2020 |  | 2021 |  | 2020 | ​ | ​
Basic weighted-average Common Shares outstanding | ​ | 27,147,150 | ​ | 26,956,286 | ​ | 27,100,484 | ​ | 27,046,899 | ​ | ​
Effect of dilutive shares | ​ | - | ​ | 266,596 | ​ | 331,034 | ​ | - | ​ | ​
Diluted weighted-average Common Shares outstanding | ​ | 27,147,150 | ​ | 27,222,882 | ​ | 27,431,518 | ​ | 27,046,899 | ​ | ​
​ There were 591,256 and 755,654 performance-based right to receive Common Shares outstanding at September 30, 2021 and 2020, respectively. The right to receive Common Shares are included in the computation of diluted earnings per share based on the number of Common Shares that would be issuable if the end of the quarter were the end of the contingency period.
