Diluted Earnings Per Share

Due to the net loss in the three months ended March 31, 2015 and 2014, all common stock equivalents were excluded from the computation of diluted earnings per share due to their anti-dilutive effect.

Certain of our restricted stock units participate in dividend distributions, however, the distributions for these restricted stock units do not have a material impact on our earnings per share calculation.
