Summary of Significant Accounting Policies [Abstract] |
Weighted-average common shares for the computation of EPS | Earnings Per Share The difference between basic and diluted earnings per share (“EPS“) is the dilutive effect of stock options and nonvested stock. Diluted EPS assumes that nonvested stock has vested and all dilutive stock options, for which the average market price exceeds the exercise price (in-the-money), are exercised. Stock options for which the exercise price exceeds the average market price (out-of-the-money) have an anti-dilutive effect on EPS, and accordingly, are excluded from the calculation. Weighted-average common shares for the computation of EPS were:
