Other Events The purpose of the Current Report is to file certain financial information regarding Exelon Corporation and Subsidiary Companies. Such financial information is set forth in the exhibits to this Current Report. Explanatory Note. This amendment to Exelon Corporation's (Exelon) Annual Report on Form 8-K for the period ended December 31, 2001 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. See Note 2. No attempt has been made in this Form 8-K/A to modify or update other disclosures as presented in the original Form 8-K except as required to reflect the effects of the restatements.
