Item 5.  Other Events

On May 9, 2003, FirstEnergy Corp. (Company) amended its Form 10-K for the year
ended December 31, 2002. The Company recorded a net charge to income during the
year ended December 31, 2002, of $57.1 million (net of income taxes of $13.6
million) relating to decisions to retain interests in two businesses previously
classified as "Assets Pending Sale": Avon Energy Partners Holdings (Avon) and
GPU Empresa Distribuidora Electrica Regional S.A. and affiliates (Emdersa). This
net charge represents the aggregate results of operations of Avon and Emdersa
for the respective periods these businesses were held for sale. This charge was
previously reported on the Consolidated Statement of Income for the year ended
December 31, 2002, as a cumulative effect of a change in accounting. In April
2003, it was determined that this charge should instead have been classified in
operations. The amended Form 10-K reflects this change on the Consolidated
Statement of Income for the year ended December 31, 2002. This change in
classification had no effect on previously reported net income.
