Represents the effect of the assumed exercise of stock options and the vesting of restricted stock units and performance stock awards, based on the treasury stock method.
 
Due to the Company’s net loss in the nine month period ended September 30, 2016, and the net loss in the three and nine month periods ended September 30, 2015, the assumed exercise of stock options and the vesting of restricted stock units and performance stock awards using the treasury stock method would have had an antidilutive effect and were therefore excluded from the computation of diluted loss per share. The weighted average number of such antidilutive shares not included in the computation of diluted loss per share was 181,000 for the nine month period ended September 30, 2016, and 163,000 and 185,000 for the three and nine month periods ended September 30, 2015, respectively.
 
In the three months ended September 30, 2016, there were 27,000 shares from the assumed exercise of stock options and the vesting of restricted stock units using the treasury stock method that were excluded from the calculation of diluted earnings per share because to include these shares would have had an antidilutive effect
