Item 5. Other Events On August 27, 2002, Commonwealth Edison Company (ComEd) received a Letter Order from the Deputy Executive Director and Chief Accountant of the Federal Energy Regulatory Commission (FERC) directing ComEd to remove from its books the amount of goodwill associated with the generating assets and power marketing business that ComEd transferred in January 2001 as part of an Exelon Corporation (Exelon) corporate restructuring to separate generation assets from transmission and distribution assets. The Letter Order also stated that the FERC Staff had been informed by the SEC Staff that the matter was under review. The Letter Order was in response to a request made by ComEd in July 2001 for approval by FERC of accounting entries related to that corporate restructuring. Since receiving the letter, representatives of Exelon and ComEd have provided information to the FERC as well as to the Office of the Chief Accountant of the Securities and Exchange Commission (SEC). While the matter is still under review by the FERC, Exelon and ComEd understand that the Office of the Chief Accountant of the SEC will not object to the accounting treatment for goodwill that resulted from the application of purchase accounting with respect to the October 2000 merger and the subsequent January 2001 restructuring. The accounting for the restructuring reflected the attribution of goodwill to the transmission and distribution business of ComEd. No further proceedings at the SEC are required with respect to this matter. For additional information, see Exelon's and ComEd's Current Reports on Form 8-K dated August 27, 2002 and September 3, 2002.
