Item 8.01                      Other Events

Reference is made to the text on page I-2 of Management’s Financial Discussion and Analysis of Results of Operations incorporated into the Annual Report on Form 10-K for the year ended December 31, 2007 of Columbus Southern Power Company (the “Company”) appearing under the caption titled Ohio Restructuring.  The current Ohio restructuring legislation permits the Company to implement market-based rates effective January 2009, following the expiration of its rate stabilization plan (“RSP”) on December 31, 2008.  The RSP plan includes generation rates which are between cost and higher market rates.  In April 2008, the Ohio legislature passed legislation which allows utilities to set prices by filing an Electric Security Plan along with the ability to simultaneously file a Market Rate Option.  The Public Utilities Commission of Ohio (“PUCO”) would have authority to approve or modify the utility’s request to set prices.  Both alternatives would involve earnings tests monitored by the PUCO.  The legislation still must be signed by the Ohio governor to become law.  Management is analyzing the financial statement implications of the proposed legislation and has not determined at this time whether the proposed legislation results in a form of cost-based regulation for its generation supply business on January 1, 2009.  A return to cost-based regulation could cause the Company’s generation business, in whole or in part, to meet the criteria for application of SFAS 71.  If the Company is required to reestablish certain net regulatory liabilities applicable to its generation business, it could result in an extraordinary item and a decrease in future results of operations and financial condition.
