FirstEnergy Corp. revised earnings guidance for the full year of 2011. The company announced it has adopted a new policy that changes the method of accounting for pensions and other post-retirement benefits (OPEB). The company said it expects to report full-year 2011 basic non-GAAP earnings of $3.63 to $3.65 per share of common stock, up from its previous guidance of $3.30 to $3.50 per share. On a GAAP basis, the company expects full-year 2011 basic earnings of $2.44 to $2.46 per share. These 2011 GAAP and non-GAAP earnings expectations include a $0.22 per share benefit as a result of the pension and OPEB accounting change. GAAP earnings expectations for 2011 also include a $0.73 per share decrease due to the mark-to-market impact of the new accounting method, and a charge of $0.38 per share related to the plant retirements.
