Certain  information  and footnote  disclosures  normally  included in financial
statements prepared in accordance with generally accepted accounting  principles
have been condensed or omitted pursuant to such rules and regulations,  although
Cinergy Corp., The Cincinnati Gas & Electric  Company,  PSI Energy Inc., and The
Union Light, Heat and Power Company believe that the disclosures are adequate to
make the information presented not misleading.  In the opinion of Cinergy, CG&E,
PSI, and ULH&P,  these statements reflect all adjustments (which include normal,
recurring  adjustments)  necessary to reflect the results of operations  for the
respective periods.  The unaudited statements are subject to such adjustments as
the annual audit by independent public accountants may disclose to be necessary.

Pursuant to the  requirements of Section 13 or 15(d) of the Securities  Exchange
Act of 1934,  the  Registrants  have duly  caused this report to be signed by an
officer  and the chief  accounting  officer on their  behalf by the  undersigned
thereunto duly authorized.
