[1] The fourth quarter of fiscal 2012 included 14 weeks compared to 13 weeks in the fourth quarter of fiscal 2011.

[2] Per share amounts are computed independently for each of the quarters presented. The sum of the quarters may not equal the total year due to the impact of changes in weighted shares outstanding and differing applications of earnings under the two-class method. Additionally, during the fourth quarter of fiscal 2012 there was a $0.03 reduction in earnings per diluted share due to the application of the two-class method of computing earnings per share in connection with the $1.00 per share special cash dividend paid in December 2012.
