Earnings Per Share [Abstract] |
Net Income Per Share | 13 — Net Income Per Share The table below reconciles basic weighted shares outstanding to diluted weighted average shares outstanding:
|  | Year Ended July 31,
(In thousands) |  | 2017 |  | 2016 |  | 2015
Weighted average common shares outstanding |  | 228,686 |  |  | 228,846 |  |  | 251,829 |
Effect of dilutive securities — stock options |  | 8,333 |  |  | 15,449 |  |  | 11,022 |
Weighted average common and dilutive potential common shares outstanding |  | 237,019 |  |  | 244,295 |  |  | 262,851 |
There were no material adjustments to net income required in calculating diluted net income per share. Excluded from the dilutive earnings per share calculation were 3,058,808; 11,594,014; and 11,810,748 options to purchase the Company’s common stock for the years ended July 31, 2017, 2016 and 2015, respectively, because their inclusion would have been anti-dilutive. During the year ended July 31, 2016, the Company adopted ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting, which caused an impact on dilutive potential common shares outstanding, as the Company excluded the excess tax benefits and deficiencies from the proceeds portion of the diluted earnings per share calculations as they are no longer recorded in equity, which caused dilutive potential common shares outstanding to increase for all periods in fiscal 2016.
