(1)
The Preferred Securities were anti-dilutive during 2012. They were redeemed 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 would be increased by $7.7 million, and weighted-average shares outstanding would be increased by 4.5 million.

(2)
Dilutive securities include “in the money” options, non-participating restricted stock units and performance stock units. The weighted-average shares outstanding for 2014, 2013 and 2012 exclude the effect of approximately 0.2 million, 2.3 million and 9.4 million stock options and other securities, respectively, because such securities were anti-dilutive.
Net income attributable to participating securities, which consisted of certain of the Company’s outstanding restricted stock units, was $2.5 million, $4.0 million and $3.5 million for 2014, 2013 and 2012, respectively.
