Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per Share Basic earnings per share is computed by dividing income available to common stockholders by the weighted average number of shares outstanding for the periods presented. The calculation of diluted earnings per share includes the impact of potentially dilutive non-vested restricted shares outstanding during the periods presented, unless their effect is anti-dilutive. There are no adjustments made to income available to common stockholders in the calculation of diluted earnings per share. The following is a calculation of the basic and diluted weighted-average shares outstanding for the three and six months ended June 30, 2014 and 2013:
