Earnings Per Share [Abstract] |
Earnings Per Share | Note 10 — Earnings Per Share U.S. GAAP requires the Company to use the two-class method in computing basic earnings per share since holders of the Company’s restricted stock have the right to share in dividends, if declared, equally with common stockholders. These participating securities effect the computation of both basic and diluted earnings per share during periods of net income. A summary of the numerator and denominator of the basic and diluted earnings per common share is presented below:
