A reconciliation of the weighted average shares outstanding used in the basic and diluted earnings per share computations is as follows (in thousands, except per share data):

Dilutive potential common shares consist of stock options and unvested restricted stock awards. There were 2,670 and 1,328,246 stock options excluded from the fiscal 2011 and 2009 calculation of diluted earnings per share, respectively, because their inclusion would have been anti-dilutive. No stock options were excluded from the fiscal 2010 calculation of diluted earnings per share. There were 11,284 restricted stock awards excluded from the calculation of diluted earnings per share in fiscal 2011 as compared to zero in 2010 or 2009.

For the twelve months ended August 31, 2011, 2010 and 2009, 1,672,975, 1,692,743 and 1,044,262, respectively, performance-based stock option grants were excluded from the calculation of diluted earnings per share. Performance-based stock options should be omitted from the calculation of diluted earnings per share until the performance criteria have been met. The criteria had not yet been met at August 31, 2011 and 2010 for performance-based stock options granted in fiscal 2011 and 2010.
