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 0.1 million stock options for the three months ended March 31, 2014, because such options were anti-dilutive. The weighted-average shares outstanding for the three months ended March 31, 2015 and 2014 each exclude the weighted average effect of 0.6 million performance stock units outstanding because the securities were anti-dilutive.
