Because it is the Company’s intention to redeem the principal amount of the Senior Subordinated Convertible Notes in cash, the treasury stock method is used for determining potential dilution in the diluted earnings per share computation. For the three months ended June 30, 2014, the senior subordinated convertible notes due 2019 and the 2034 Convertible Notes have been excluded from the computation of diluted earnings per share as the effect would be antidilutive, as the initial conversion price exceeded the average market price of the Company’s common stock during the three months ended June 30, 2014. As of June 30, 2014, there were 5.2 million restricted share awards with performance-based vesting targets that were not met and as such, have been excluded from the computation of diluted earnings per share.
