Net Income Per Share |
Net Income Per Share | 11. Net Income Per Share Basic net income per share is computed on the basis of the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed based upon the weighted-average number of common shares outstanding during the period plus the assumed issuance of common shares for all potentially dilutive securities. The net income used in the calculation of basic and diluted net income per share are as follows: ​

Net income available to shareholders | ​ | $ | 35,354,679 | ​ | $ | 11,627,517
​ In calculating the net income per share, basic and diluted, the following weighted-average shares were used: ​
​ | ​ | ​ | ​ | ​
​ | ​ | Year ended December 31,
