S&P AFFIRMS RATINGS ON AEP’S PARENT DEBT, COMMERCIAL PAPER

COLUMBUS, Ohio, May 23, 2002 - Standard & Poor’s affirmed its BBB+ rating on American Electric Power’s (NYSE: AEP) parent company senior unsecured debt and the A-2 rating on the company’s commercial paper program today while lowering ratings on other company entities in preparation for a planned corporate restructuring.

“We are pleased that S&P maintained its ratings in these two important areas and confirmed a stable outlook for the company and our subsidiaries,” said Susan Tomasky, AEP executive vice president and chief financial officer. “We were not surprised with other ratings changes announced by S&P in preparation for our restructuring, which we expect to complete later this year.”

AEP is awaiting regulatory approval for a corporate separation that will create a regulated utility subsidiary and a nonregulated energy subsidiary. S&P maintained the rating on the parent company debt based on AEP’s intent, as part of the restructuring, to implement legal means to make that debt pari passu with the rest of the debt in the corporate structure. In preparation for the corporate separation, S&P lowered the corporate credit rating to BBB+ from A- and lowered or assigned new ratings to various subsidiaries.
