[1] The Preferred Securities were anti-dilutive during 2012 through their redemption on July 16, 2012, and therefore, have been excluded from diluted earnings per share. Had the Preferred Securities been included in the diluted earnings per share calculation, net income for the three months ended March 31, 2012 would be increased by $3.5 million and weighted-average shares outstanding would be increased by 8.3 million shares for the three months ended March 31, 2012.

[2] Dilutive securities include “in the money” options, non-participating restricted stock units and performance stock units. The weighted-average shares outstanding exclude the effect of 3.5 million and 10.5 million stock options for the three months ended March 31, 2013 and 2012, respectively, because such securities were anti-dilutive. The weighted-average shares outstanding for the three months ended March 31, 2013 and 2012 also exclude the weighted average effect of 0.9 million and 1.0 million performance stock units outstanding at March 31, 2013 and 2012, respectively, because the securities were anti-dilutive.
