(1) Earnings for the years ended December 31, 2016 and December 31, 2015 were insufficient to cover fixed charges by $68.6 million and $740.3 million, respectively. Ratios for the years ended December 31, 2016 and December 31, 2015 include the effects of impairments on oil and gas properties of $245.5 million and $814.8 million, respectively. Excluding the impact of the impairments of oil and gas properties, the earnings/fixed charge coverage ratio for the years ended December 31, 2016 and December 31, 2015 would have been 5.3 and 2.8, respectively.
