For the three and nine months ended October 1, 2016, an aggregate of 0.747 and 0.796, respectively, of unvested restricted stock shares, restricted stock units, and stock options outstanding were excluded from the computation of diluted loss per share as we incurred a net loss during the periods. For the three and nine months ended October 1, 2016, the number of anti-dilutive unvested restricted stock shares and restricted stock units outstanding excluded from the computation of diluted loss per share was 0.119 and 0.290, respectively. For the three months ended September 26, 2015, an aggregate of 0.998 unvested restricted stock shares, restricted stock units, and stock options outstanding were excluded from the computation of diluted loss per share as we incurred a net loss during the period. For the nine months ended September 26, 2015, 0.479 of unvested restricted stock shares/units were not included in the computation of diluted income per share because required market thresholds for vesting (as discussed in our consolidated and combined financial statements included in our 2015 Annual Report on Form 10-K) were not met. For the nine months ended September 26, 2015, 0.396 of stock options were not included in the computation of diluted income per share because their exercise price was greater than the average market price of common shares.
