(1) | Restricted stock awards covering 1.0 million shares and 1.2 million shares for the three-month periods ended March 31, 2014 and 2013, respectively, were excluded from the computation of loss per share because their effect would have been antidilutive.
(2) | Potential common shares related to the Company’s outstanding 8.5%, 6.0% and 7.0% convertible perpetual preferred stock covering 90.1 million shares for both the three-month periods ended March 31, 2014 and 2013 were excluded from the computation of loss per share because their effect would have been antidilutive under the if-converted method.
