Outstanding options to purchase 5.8 million, 2.4 million and 1.4 million shares of Common Stock were excluded from the calculations of diluted earnings per share in 2016, 2015 and 2014, respectively, because the effect of their inclusion would have been antidilutive to those years. In addition, 0.9 million, 0.9 million and 1.1 million shares of performance-based RSUs were excluded from the calculations of diluted earnings per share in 2016, 2015 and 2014, respectively, because these units were not considered to be contingent outstanding shares.
