[1] | We retired all of our outstanding 4.75% Convertible Senior Notes due 2023 (the "4.75% Notes") in March 2013. For purposes of calculating diluted loss per share, the potentially dilutive shares are pro-rated based on the period they were outstanding but were antidilutive.
[2] | We converted all of our Series B Preferred Stock into common stock in October 2013.
[3] | These options are outstanding at the end of the respective periods. In any period in which the exercise price is less than the average market price, these options have the potential to be dilutive, and application of the treasury stock method would reduce this amount.
