[1] The loss on debt extinguishment of $145 million has been added back to net income in addition to interest expenses related to the convertible bonds. These effects are anti-dilutive, and exceed the effect of increased denominator when calculating the diluted earnings per share. As a consequence of this, the diluted earnings per share equal basic earnings per share.
