ITEM 4. CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.

     This Form 8-K/A amends and restates the Current Report on Form 8-K filed by
the  Registrants  on March 20, 2003 with respect to the completion of Deloitte &
Touche LLP's ("Deloitte & Touche")  services related to the audits of the fiscal
year ended December 31, 2002.

     On March 14,  2003,  the  Auditing  Committees  of CILCORP Inc. and Central
Illinois Light Company (the  "Registrants")  dismissed  Deloitte & Touche as the
Registrants'  independent  public  accountants  subject  to  completion  of  its
services related to the audits of the consolidated  financial statements for the
fiscal  year ended  December  31, 2002 and  engaged  PricewaterhouseCoopers  LLP
("PricewaterhouseCoopers")  to  serve  as the  Registrants'  independent  public
accountants  for the fiscal  year ended  December  31,  2003.  The  Registrants'
Auditing  Committees made this  replacement  because  PricewaterhouseCoopers  is
serving  as the  independent  public  accountants  for the  Registrants'  parent
company,  Ameren  Corporation,  for the fiscal year 2003. The  Registrants  were
acquired by Ameren  Corporation in early 2003.  Deloitte & Touche  completed its
services related to the audits of the consolidated  financial statements for the
fiscal  year ended  December  31,  2002 with the  issuance of its reports on the
Registrants'  consolidated financial statements included in the Annual Report on
Form 10-K for the fiscal year ended  December 31, 2002 filed by the  Registrants
on April 15,  2003.  Deloitte & Touche  will no longer  provide  services as the
Registrants' principal independent auditors.

     Deloitte &  Touche's  reports on the  Registrants'  consolidated  financial
statements for the fiscal years ended December 31, 2002 and 2001 did not contain
an adverse  opinion or a  disclaimer  of  opinion,  nor were they  qualified  or
modified as to uncertainty, audit scope or accounting principles.

     During the  Registrants'  two fiscal years ended December 31, 2002 and 2001
and the  subsequent  interim  period  through  April  15,  2003,  there  were no
disagreements  with Deloitte & Touche on any matter of accounting  principles or
practices,  financial statement disclosure or auditing scope or procedure which,
if not  resolved  to Deloitte & Touche's  satisfaction,  would have caused it to
make  reference  to the  subject  matter in  connection  with its reports on the
Registrants' consolidated financial statements for such years, and there were no
reportable events, as listed in Item 304(a) (1) (v) of Regulation S-K.

     The  Registrants  have  provided  Deloitte  &  Touche  with a  copy  of the
foregoing disclosures. Attached as Exhibit 16.1 is a copy of Deloitte & Touche's
letter, dated April 22, 2003, stating its agreement with such statements.

     During the  Registrants'  two fiscal years ended December 31, 2002 and 2001
and the subsequent  interim period through April 15, 2003, the  Registrants  did
not consult  PricewaterhouseCoopers  regarding  the  application  of  accounting
principles to a specified  transaction,  either contemplated or proposed, or the
type of audit  opinion that might be rendered on the  Registrants'  consolidated
financial  statements,  or any other  matter or  reportable  event that would be
required to be reported in this Current Report on Form 8-K/A.
