As a result of the net loss reported for the three and nine months ended September 30, 2016, all then outstanding stock options, restricted stock awards and performance awards totaling 835,482 were excluded from the calculation of diluted (loss) earnings per share as their inclusion would have an antidilutive effect. 

For the three and nine months ended September 30, 2015, the dilutive effect of all then outstanding options, restricted stock and performance awards is included in the EPS calculations above except for 274,257 of outstanding performance stock awards for which the performance criteria were not attained at that time and 10,704 and 42,642, respectively, of restricted stock awards which were antidilutive at that time.
