Earnings Per Share [Abstract] |
Computation of Earnings Per Share | Computation of Earnings Per Share Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of shares of Common Stock outstanding during the period. Diluted EPS reflects the potential dilution of securities that could share in earnings. Potential shares of common stock are excluded from the computation of diluted earnings per share when their effect would be anti-dilutive. The table below sets forth the calculation of basic and diluted income per share for the periods indicated (in thousands, except per share data).
