[1] The Preferred Securities were anti-dilutive during 2012 and 2011 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 2012 and 2011 would be increased by $7.7 million and $14.0 million, respectively. Weighted-average shares outstanding would be increased by 4.5 million and 8.3 million shares for 2012 and 2011, respectively.

[2] Dilutive securities include “in the money” options, non-participating restricted stock units and performance stock units. The weighted-average shares outstanding for 2013, 2012 and 2011 exclude the effect of approximately 2.3 million, 9.4 million and 12.4 million stock options and other securities, respectively, because such securities were anti-dilutive.
