(1)
Participating securities include restricted stock that has been issued but has not yet vested.
(2)
Entities with a net loss from continuing operations are prohibited from including potential common shares in the computation of diluted per share amounts. We have utilized the basic shares outstanding to calculate both basic and diluted loss per share for the three and nine months ended September 30, 2016.
