Income (Loss) Per Share (EPS)

Note 5— Income (Loss) Per Share ("EPS")

Basic EPS is computed by dividing net income (loss) available to common shareholders by the weighted average number of common shares, excluding unvested restricted stock, outstanding during the period. Diluted EPS is computed by dividing net income (loss) available to common shareholders by the weighted average number of common and potential common shares outstanding during the period, which includes the additional dilution related to conversion of stock options, unvested restricted stock and unvested restricted stock units as computed under the treasury stock method.

For the three and nine months ended September 30, 2016 , outstanding stock options, unvested restricted stock and unvested restricted stock units were antidilutive because of the net losses and, as such, their effect has not been included in the calculation of basic or diluted net loss per share. For the three and nine months ended September 30, 2015, the added shares from these items included in the calculation of diluted shares and EPS totaled 0.9 million and 1.4 million, respectively. For the three and nine months ended September 30, 2016, potential gross common shares of 2.7 million and 2.7 million, respectively, were antidilutive and not included in computing diluted EPS. For the three and nine months ended September 30, 2015, potential gross common shares of 1.4 million and 1.3 million, respectively, were antidilutive and not included in computing diluted EPS. An additional 1.2 million and 1.3 million performance vesting restricted stock and performance vesting restricted stock units were excluded from the computation of potential common shares for the three and nine months ended September 30, 2016 and 2015, respectively, because the conditions for vesting had not been met as of the balance sheet date.
