Earnings (Loss) Per Common Share [Abstract] |
Earnings (Loss) Per Common Share | 18. Earnings (Loss) Per Common Share Basic earnings (loss) per common share is computed by dividing the net income (loss) allocated to common stockholders by the weighted-average number of shares of common stock outstanding during the period. For purposes of calculating diluted earnings per common share, the denominator includes both the weighted-average number of shares of common stock outstanding during the period and the number of common stock equivalents if the inclusion of such common stock equivalents is dilutive. Dilutive common stock equivalents potentially include stock options and warrants using the treasury stock method. The following table summarizes the components of the earnings (loss) per common share calculation (in thousands, except per share amounts): ​

​ | ​ | ​ | ​ | ​
​ | ​ | June 30,
