(a)

The weighted average common shares issuable upon the assumed conversion of the mandatory convertible preferred stock totaling of 5,048,824 and 5,495,861 for the three months ended September 30, 2017 and 2016, respectively, and 5,152,582 and 5,590,105 for the nine months ended September 30, 2017 and 2016, respectively, were excluded from the computation of diluted earnings (loss) per share as such conversion would have been anti-dilutive.

(b)

Due to the net loss for the nine months ended September 30, 2017 dilutive loss per share is the same as basic.
