This Amendment No. 1 to the Exelon Corporation Form U5S Annual Report for the year ended December 31, 2001, is being filed to update Items 1, 6 and 10 for information previously not reported in Exelon Corporation's Form U5S filed on May 1, 2002. Additionally, Item 10 reflects a restatement as a result of a $101 million double posting of deferred income taxes recorded associated with unrealized losses on Exelon Generation Company, LLC's (Generation) nuclear decommissioning trust fund securities. Additionally, Exelon and Generation determined that Other Comprehensive Income should be restated for the amount of $27 million to reflect Generation's ownership interest in the Other Comprehensive Income of its equity investments in AmerGen Energy Company, LLC and Sithe Energies Inc. Earnings per share, net income and cash flow for the periods are not affected by the restatements. However, Other Comprehensive Income, which is a component of Shareholders' Equity, will be reduced by a total of approximately $128 million as of December 31, 2001 as a result of the revision.
