________________________________________________________


(1)	Entities with a net loss are prohibited from including potential common shares in the computation of diluted per share amounts; therefore, we have utilized the basic shares outstanding to calculate both basic and diluted loss per share for the three and six months ended June 30, 2014.


(2)	Participating securities includes restricted stock that has been issued but is not yet vested.
