| Reconciliation of Weighted Average Number of Shares | A reconciliation of the number of shares used for the basic and diluted (loss) earnings per share (“EPS”) computations is as follows: Three Months Ended September 30, Nine Months Ended September 30, 2015 2014 2015 2014Weighted average common shares outstanding for basic EPS439 436 438 437Adjustment for effect of dilutive securities - stock plans— 2 — 3Weighted average common shares outstanding for diluted EPS439 438 438 440        Anti-dilutive shares excluded from diluted EPS (1)1 — 2 —Future potentially dilutive shares excluded from diluted EPS (2)3 2 3 2(1) The calculation of diluted net loss per share for both the three and nine months ended September 30, 2015, excludes shares potentially issuable under stock-based incentive compensation plans and the employee stock purchase plan, as their effect, if included, would have been anti-dilutive.(2) Options where the exercise price exceeds the average market price are excluded from the calculation of diluted net loss or earnings per share because their effect would be anti-dilutive. |
