[1] The operating loss for the E&P segment includes a $441.5 million and $1,377.4 million non-cash ceiling test impairment of our natural gas and oil properties for the three and nine-months ended September 30, 2012 respectively.

[2] Interest income, interest expense and the provision for income taxes by segment are allocated as they are incurred at the corporate level.

[3] (1) As we recognized a net loss for the three- and nine-months ended September 30, 2012, the unvested share-based payments and stock options were not recognized in diluted earnings per share (“Diluted EPS”) calculations as they would be antidilutive. Options for 1,664,232 shares and 560,848 shares of restricted stock were excluded from the calculation for the three months ended September 30, 2012 because they would have had an antidilutive effect. Options for 783,823 shares and 5,645 shares of restricted stock were excluded from the calculation for the three months ended September 30, 2011 because they would have had an antidilutive effect. Options for 1,685,398 shares and 580,227 shares of restricted stock were excluded from the calculation for the nine months ended September 30, 2012 because they would have had an antidilutive effect. Options for 811,552 shares and 7,114 shares of restricted stock were excluded from the calculation for the nine months ended September 30, 2011 because they would have had an antidilutive effect.
