Item 8. Change in Fiscal Year

On December 5, 2001, the Board of Directors of Energen Corporation (Energen or the Company) made a determination to change the registrant's fiscal year end from September 30 to December 31, effective immediately. Energen filed an Annual Report on Form 10-K with the Securities and Exchange Commission with regard to the 12-month fiscal year ending September 30, 2001, on December 7, 2001. In February 2002, the Company will file a Form 10-Q transition report with the Securities and Exchange Commission for the three-months ended December 31, 2001. Audited financial statements covering both the three-months ended December 31, 2001, and the 12-months ended December 31, 2002, will be part of the Company's 10-K filing in March 2003.

Natural gas distribution companies historically have utilized a September 30 year-end in keeping with the seasonal nature of that business. Over the last six years, Energen's business mix has shifted significantly with Energen's oil and gas acquisition and exploitation company representing approximately 60 percent of Energen's assets and consolidated earnings. Management believes that as Energen moves toward a more diverse business mix, it is appropriate to adopt the reporting period most widely observed in the diversified energy and oil and gas industries. Moving to a December 31 year-end aligns Energen's financial reporting with its peer group and the majority of publicly held corporations in the United States.
