Basic earnings per share (EPS) is based on the weighted average number of common shares outstanding for the period, excluding any dilutive common share equivalents. Diluted EPS reflects the potential dilution resulting from vesting of restricted shares of common stock. The following table shows the computation of basic and diluted EPS for the years ended December 31, 2014, 2013 and 2012:
