Earnings represents income before income taxes from continuing operations before fixed charges. Due to the $98.9 million con-cash charge incurred in the fourth quarter of 2001 caused by a write-down in the carrying value of oil and gas properties, 2001 earnings were insufficient by $40.2 million to cover fixed charges in this period. If the $98.9 million non-cash charge is excluded, the ratio of earnings to fixed charges would have been 4.09 for 2001.
