ITEM 5. OTHER EVENTS
Reference is made to Item 1. Business under the captions "General",
"Capital Program and Financing" and "Regulation" and Item 2. Properties in the
Registrant's Form 10-K for the year ended December 31, 1999, and to Management's
Discussion and Analysis of Financial Condition and Results of Operations under
the caption "Electric Industry Restructuring" in the 1999 Annual Report to
Stockholders pages incorporated by reference under Item 7 of the 1999 Form 10-K,
for a discussion of the plan of Central Illinois Public Service Company
(AmerenCIPS), the Registrant's subsidiary, to transfer its electric generating
facilities to a new nonregulated subsidiary of the Registrant pursuant to
Illinois' Electric Service Customer Choice and Rate Relief Law of 1997.
On May 1, 2000, following the receipt of all required State and Federal
regulatory approvals, AmerenCIPS' transferred its electric generating assets and
liabilities to a newly created nonregulated company, Ameren Energy Generating
Company (Generating Company), a wholly-owned subsidiary of the Registrant, in
exchange for a promissory note from Generating Company in the principal amount
of approximately $600 million (the net book value of the assets and liabilities)
and Generating Company common stock. The promissory note has a term of five
years and bears interest at 7% based on a 10-year amortization. The transferred
assets represent a generating capacity of approximately 2,900 megawatts.
Approximately 45% of AmerenCIPS' employees were transferred to Generating
Company as a part of the transaction.
Also on May 1, 2000, an electric power supply agreement was entered into
between Generating Company and its newly created nonregulated affiliate, Ameren
Energy Marketing Company (Marketing Company). On the same date, Marketing
Company entered into an electric power supply agreement with AmerenCIPS to
supply it sufficient power to meet native load requirements. This agreement
expires December 31, 2004. Power will continue to be jointly dispatched between
Union Electric Company, another subsidiary of the Registrant, and Generating
Company.
The creation of the new subsidiaries and the transfer of AmerenCIPS'
generating assets and liabilities had no effect on the financial statements of
the Registrant as of the date of transfer.
