Common stock warrants not assumed if converted | 6,200,000 |  |  |  |  |
[1] | Since we recognized net income for the fiscal years ended August 31, 2012 and August 31, 2011, basic weighted average shares for those periods includes 3.3 million shares of common stock held by management stock loan participants that were placed in escrow. These shares were excluded from basic weighted-average shares for the fiscal year ended August 31, 2010.
[2] | For the fiscal year ended August 31, 2010, the conversion of 6.2 million common stock warrants is not assumed because such conversion would be anti-dilutive.
