Earnings Per Share [Abstract] |
Earnings (Loss) Per Share | Basic earnings (loss) per share is calculated by dividing net income (loss) available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings (loss) per share is calculated by dividing net income (loss) available to common stockholders that has been adjusted for dilutive securities, by the weighted-average number of common shares outstanding including dilutive securities. The following is a reconciliation of the calculation of basic and diluted loss per share (in thousands, except share and per-share data):
