[1] Stock options and unvested stock of 10.3 million shares and 14.5 million shares for the three months ended March 31, 2015 and 2014, respectively, representing securities that could potentially dilute basic EPS in the future were not included in the diluted net loss per share computations because their effect would have been anti-dilutive. In addition, 21.1 million shares in aggregate, issuable upon conversion of the 2021 Convertible Unsecured Notes and the 2045 Convertible Senior Notes, as described in Note 7—Long-Term Debt, were not included in the computation of diluted net loss per share for 2015 because the computation of diluted net loss per share utilizing the “if-converted” method would be anti-dilutive.
