(13) |  | Net Income Per Share
The table below reconciles weighted average shares outstanding to weighted average shares and dilutive potential share outstanding (in thousands):
|  |  |  | Years Ended July 31, |
--- | --- | --- | --- | --- | ---
|  |  |  | 2011 |  | 2010 |  | 2009
Weighted average common shares outstanding |  |  |  |  | 75,649 |  |  |  | 84,165 |  |  |  | 83,537 |
Effect of dilutive securities-stock options |  |  |  |  | 1,027 |  |  |  | 862 |  |  |  | 1,393 |
Diluted weighted average common shares outstanding |  |  |  |  | 76,676 |  |  |  | 85,027 |  |  |  | 84,930 |
There were no adjustments to net income required in calculating diluted net income per share. Excluded from the dilutive earnings per share calculation were 2,553,989, 5,892,641 and 1,225,000 options to purchase our common stock that were outstanding at July 31, 2011, 2010 and 2009, respectively, because their effect would have been anti-dilutive.
