[1] As a result of the net loss per share for each of the three and six months ended July 1, 2012 and July 3, 2011, the inclusion of all potentially dilutive stock options, restricted stock units, and common shares under the 4.75% debentures would be anti-dilutive. Therefore, those stock options, restricted stock units and shares were excluded from the computation of the weighted-average shares for diluted net loss per share for such period.
