Item 5.  Other Events

        This Current Report on Form 8-K (Report) is limited to the impact of
updating the business segments of American Electric Power Company, Inc. (AEP),
AEP Texas Central Company (TCC), AEP Texas North Company (TNC), Appalachian
Power Company (APCo), Columbus Southern Power Company (CSPCo), Indiana Michigan
Power Company (I&M), Kentucky Power Company (KPCo), Ohio Power Company (OPCo),
Public Service Company of Oklahoma (PSO) and Southwestern Electric Power Company
(SWEPCo) (collectively, the Registrants), to reflect the new reportable segments
originally reported in the combined Report on Form 10-Q for the period ended
March 31, 2003, and the impact upon management's discussion and analysis, the
financial statements and the related notes, and the selected financial data as
originally reported in our Annual Report on Form 10-K and Form 10-K/A (for AEP)
for the fiscal year ended December 31, 2002 (Form 10-K and Form 10-K/A (for
AEP)). NO ATTEMPT HAS BEEN MADE IN THIS REPORT TO MODIFY OR UPDATE OTHER
DISCLOSURES EXCEPT AS REQUIRED TO REFLECT THE EFFECTS OF THE NEW REPORTABLE
SEGMENTS.

         As previously disclosed in our Quarterly Report on Form 10-Q for the
quarter ended March 31, 2003, we realigned our business segments from Wholesale,
Energy Delivery, and Other to Utility Operations, Investments-Gas Operations,
Investments-UK Operations and Investments-Other. These new segments are
consistent with how management establishes strategic goals, allocates resources
and evaluates performance. Our first quarter 2003 Form 10-Q, previously filed
with the Securities and Exchange Commission, reflects such segment changes. This
Report provides updated information to conform information presented in our
Annual Report to the presentation reported in our first quarter Form 10-Q.
Accordingly, this Report provides additional information to that previously
reported in our Form 10-K and Form 10-K/A (for AEP) in Item 1. Business, Item 6.
Selected Financial Data, Item 7. Management's Discussion and Analysis of
Financial Condition and Results of Operations, Item 7A. Quantitative and
Qualitative Disclosures About Market Risk, Item 8. Financial Statements and
Supplementary Data, and Item 15. Exhibits, Financial Statement Schedules and
Reports on Form 8-K to reflect the aforementioned segment changes.
