8.	Income (Loss) per Share

Basic per share data is computed by dividing net income or loss applicable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted per share data is computed by dividing net income or loss applicable to common stockholders by the weighted average number of common shares outstanding during the period increased to include, if dilutive, the number of additional common shares that would have been outstanding as calculated using the treasury stock method. Potential common shares were related entirely to outstanding but unexercised options and warrants for all periods presented.

We have included 4.2 million dilutive securities for the purposes of calculating earnings per share for the three months ended September 30, 2015. We have excluded all potentially dilutive securities, including unvested performance-based restricted stock, from the calculation of diluted loss per share attributable to common stockholders for the nine month period ended September 30, 2015 and three and nine month periods ended September 30, 2014, as their inclusion would be antidilutive. Potentially dilutive common shares excluded from the calculations of diluted loss per share were 62.9 million for the nine month periods ended September 30, 2015 and 18.7 million for the three and nine month periods ended September 30, 2014, respectively.
