Basic net income (loss) per share is computed using the weighted average number of common shares outstanding during the period, excluding any unvested restricted stock awards that are subject to repurchase. Diluted net income (loss) per share is computed using the treasury stock method to calculate the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential dilutive common shares include unvested restricted stock awards and units and incremental common shares issuable upon the exercise of stock options, less shares from assumed proceeds. The assumed proceeds calculation includes actual proceeds to be received from the employee upon exercise, the average unrecognized stock compensation cost during the period and any tax benefits that will be credited upon exercise to additional paid-in capital.

For the three and six months ended June 30, 2013 calculation of earnings per share for net loss, all 2.6 million shares and 3.5 million shares, respectively, subject to stock options and restricted stock awards and units were excluded from the computation of diluted net income per share as they were anti-dilutive.

For the three and six months ended June 30, 2012 calculation of earnings per share for net loss, all 5.3 million shares and 6.5 million shares, respectively, subject to stock options and restricted stock awards and units were excluded from the computation of diluted net income per share, as they were anti-dilutive.
