Earnings Per Share [Abstract]  
Net Income (Loss) Per Share
Net Income Per Share:

We compute basic net income per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. To determine diluted share count, we apply the treasury stock method to determine the dilutive effect of outstanding stock option shares, restricted stock units ("RSUs"), and Employee Stock Purchase Plan ("ESPP") shares. Our application of the treasury stock method includes, as assumed proceeds, the average unamortized stock-based compensation expense for the period and the impact of the pro forma deferred tax benefit or cost associated with stock-based compensation expense.

A reconciliation of basic and diluted Net income per share is presented below (in thousands, except per share data):

The computation of diluted Net income per share for the three months ended June 28, 2014 and June 29, 2013, respectively, includes the effects of stock options, RSUs and ESPP shares aggregating approximately 3.0 million and 1.4 million, respectively, as they are dilutive, and excludes the effects of stock options, RSUs and ESPP shares aggregating approximately 1.7 million and 9.6 million, respectively, as they are antidilutive. The computation of diluted Net income per share for the six months ended June 28, 2014 and June 29, 2013, respectively, includes the effects of stock options, RSUs and ESPP shares aggregating approximately 2.9 million and 1.4 million, respectively, as they are dilutive, and excludes the effects of stock options, RSUs and ESPP shares aggregating approximately 2.3 million and 8.2 million, respectively, as they are antidilutive. Stock options, RSUs and ESPP shares are considered antidilutive when the aggregate of exercise price, unrecognized stock-based compensation expense and excess tax benefit are greater than the average market price for our common stock during the period or when the Company is in a net loss position, as the effects would reduce the loss per share. Stock options, RSUs and ESPP shares that are antidilutive at June 28, 2014 could become dilutive in the future.
