Earnings Per Share [Abstract] |
Net Income (Loss) per Share | 13. Net Income (Loss) per Share The following is a calculation of basic and diluted net income (loss) per share (in millions, except per share amounts):
|  | Three Months Ended |
|  | July 31, 2015 |  |  | July 25, 2014 |
Numerator: |  |  |  |  |  |  |  |
Net income (loss) |  | $ | (30 | ) |  | $ | 88 |
Denominator: |  |  |  |  |  |  |  |
Shares used in basic computation |  |  | 304 |  |  |  | 323 |
Dilutive impact of employee equity award plans |  |  | — |  |  |  | 6 |
Shares used in diluted computation |  |  | 304 |  |  |  | 329 |
Net Income (Loss) per Share: |  |  |  |  |  |  |  |
Basic |  | $ | (0.10 | ) |  | $ | 0.27 |
Diluted |  | $ | (0.10 | ) |  | $ | 0.27 |
We have excluded 31 million and 8 million weighted-average shares of common stock potentially issuable under employee equity award plans in the three months ended July 31, 2015 and July 25, 2014, respectively, from the diluted net income (loss) per share calculations as their effect would have been anti-dilutive.
