Item 8.01		Other Events
		Under certain contractual arrangements entered into by subsidiaries of Pepco Holdings, Inc. ("PHI") in connection with various competitive energy and other transactions, a downgrade of one or more levels in the credit ratings of PHI and its subsidiaries by one or more rating agencies requires PHI or the subsidiaries to provide additional cash collateral or letters of credit as security for the performance by the subsidiaries of their contractual obligations.
		On July 11, 2006, Moody's Investors Service ("Moody's") announced a one-level downgrade of the debt of PHI and certain of its subsidiaries. Based on the contractual arrangements in place as of July 11, 2006, this downgrade will require PHI and its subsidiaries to provide aggregate additional security in the amount of approximately $35 million. If any other rating agency also were to downgrade the debt of PHI and its subsidiaries by one level, PHI and its subsidiaries would have been required, as of July 11, 2006, to provide aggregate additional security in the amount of between approximately $20 million and $25 million. PHI and its subsidiaries intend to satisfy these increased obligations through existing short-term funding sources.
