Report
of Independent Registered Public Accounting Firm
To
the
Participants and Administrator of the
Ameren
Corporation
Savings
Investment Plan
In
our
opinion, the accompanying statements of net assets available for benefits
and
the related statements of changes in net assets available for benefits present
fairly, in all material respects, the net assets available for benefits of
the
Ameren Corporation Savings Investment Plan (the “Plan”) at December 31, 2004 and
2003, and the changes in net assets available for benefits for the years
then
ended in conformity with accounting principles generally accepted in the
United
States of America. These financial statements are the responsibility of the
Plan’s management. Our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with the standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining,
on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our
opinion.
Our
audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets
(held
at end of year) is presented for the purpose of additional analysis and is
not a
required part of the basic financial statements but is supplementary information
required by the Department of Labor’s Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of 1974. This
supplemental schedule is the responsibility of the Plan’s management. The
supplemental schedule has been subjected to the auditing procedures applied
in
the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.
The
schedule of assets (held at end of year) that accompanies the Plan’s financial
statements does not disclose the historical cost of certain
nonparticipant-directed Plan assets held by the Plan’s trustee. Disclosure of
this information is required by the Department of Labor’s Rules and Regulations
for Reporting and Disclosure under the Employee Retirement Income Security
Act
of 1974.

Description
of the Plan
General
The
following is a brief summary of the various provisions of the Ameren Corporation
(“Ameren” or the “Company”) Savings Investment Plan (the “Plan”). Participants
should refer to the Plan document for more complete information.
The
Plan's purpose is to provide certain management and contract employees (the
“Participants”) of the Company and its wholly owned subsidiaries the option to
defer a portion of their annual base compensation for federal income tax
purposes in accordance with Section 401(k) of the Internal Revenue Code (the
“Code”). The Plan is subject to certain provisions of ERISA, as amended, and
regulations of the Securities and Exchange Commission.
The
Company serves as sponsor of the Plan, and, consequently, has the authority
to
amend or terminate the Plan subject to certain restrictions. The Board of
Directors of the Company has the authority and responsibility for the general
administration of the Plan. The Northern Trust Company, as Trustee, has the
authority and responsibility to hold and protect the assets of the Plan in
accordance with Plan provisions and with the Ameren Corporation Savings
Investment Master Trust Agreement.
On
January 31, 2003, the Company completed its acquisition of all of the
outstanding common stock of CILCORP Inc. from The AES Corporation (“AES”). With
the acquisition, CILCORP Inc. became an Ameren subsidiary. Central Illinois
Light Company is a wholly owned subsidiary of CILCORP Inc.
Effective
January 1, 2004, the Plan was amended to merge the assets of the Employees’
Savings Plan of Central Illinois Light Company into the Plan. The assets
transferred from the Employees’ Savings Plan of Central Illinois Light Company
consisted of 29,766 and 931,778 shares of Ameren and AES common stock,
respectively, as of the date of the transfer with a fair market value of
$1,369,236 and $8,795,984, respectively. In addition, cash of $96,652,880,
receivables of $320,628, loan balances of $2,662,215 and accrued expenses of
$1,551 were transferred into the Plan.
Effective
April 16, 2004, the Plan was amended to merge the assets of the CILCORP
Infraservices, Inc. 401(k) Plan (“CILCORP Plan”) into the Plan. The assets
transferred from the CILCORP Plan into the Plan consisted of cash of
$167,308.
The
Plan
was amended effective October 1, 2004, to allow all active employees of Illinois
Power Company to participate in the Plan, following the Company’s completion of
the acquisition of Illinois Power Company from Dynegy Inc. on September 30,
2004.
Effective
March 16, 2005, the Plan was amended to merge the assets of the Ameren
Corporation Employee Long-Term Savings Plan - IUOE No. 148 into the Plan. The
assets transferred into the Plan consisted of 222,879 shares of Ameren common
stock, with a fair market value as of the date of the transfer of $11,400,786.
In addition, cash of $17,049,112 and loan balances of $812,572 were transferred
into the Plan.

Participation
The
Plan
covers substantially all employees of the Company, except contract employees
covered by a collective bargaining agreement between Central Illinois Public
Service Company (“AmerenCIPS”) Local 148 IUOE and the Company, prior to March
16, 2005, and contract employees covered by a collective bargaining agreement
between AmerenCIPS Local 702 IBEW and the Company. All regular full time
employees are eligible to participate upon employment.
Contributions
Prior
to
July 1, 2003, contract participants were permitted to contribute from one to
15
percent of their base compensation to the Plan through payroll deductions.
Effective July 1, 2003, the Company amended the Plan to permit contract
participants to contribute from one to 100 percent of their base compensation
to
the Plan through payroll deductions. Prior to January 1, 2004, management
participants were permitted to contribute from one to 50 percent of their base
compensation to the Plan through payroll deductions. Effective January 1, 2004,
the Company amended the Plan to permit all Participants to contribute a maximum
of 100 percent of their base compensation to the Plan. Participant contributions
are subject to annual limitations imposed by the Code ($13,000 in 2004 and
$12,000 in 2003). The Company will make an Employer Basic Matching Contribution
plus an Employer Additional Matching Contribution in an amount equal to a
percent of the amount each Participant contributes to the Plan, up to a certain
maximum percentage of the Participant’s compensation that he or she elects to
contribute to the Plan each year. The amount of Company matching contribution
depends on the Participant’s employment classification and for contract
employees is determined by the collective bargaining agreement with the specific
union representing the Participants. The Employer Additional Matching
Contributions are invested in the Ameren Common Stock Fund; and, will remain
invested in the Ameren Common Stock Fund until Participants reach age 55. At
age
55, Participants are given the opportunity to allocate these contributions
to
different investments if so desired. All Company contributions are made to
the
extent sufficient earnings are available, as described in the Plan
document.
The
Plan
permits “catch-up” contributions for all employees age 50 and older. Eligible
employees could contribute $3,000 in 2004 and $2,000 in 2003 as a “catch-up”
contribution. The Company does not match “catch-up” contributions.
Participants
direct their contributions and the Company's Basic Matching Contributions by
electing that such contributions be placed in a single investment fund or
allocated in increments of one percent to any combination of investment funds.
Such fund allocation elections may be changed daily. Earnings derived from
the
assets of any investment fund are reinvested in the fund to which they relate.
Participants may elect daily to reallocate, by actual dollar or percentage
in
one percent increments, the value of their accounts between funds. Pending
investment of the assets into any investment fund, the Trustee may temporarily
make certain short-term investments.
Participant
Loans
The
Plan
permits Participants to borrow from their accounts within the Plan. Such
borrowings may be made subject to the following: (1) the minimum amount of
the
loan is $1,000, (2) the amount of the loan may not exceed the lesser of $50,000
or fifty percent of the vested amount in the Participant's account, (3) the
loan
will bear a fixed interest rate and repayments will be made through mutual
agreement subject to certain statutory repayment time limits, (4) each loan
shall
Ameren
Corporation
Savings
Investment Plan
Notes
to Financial Statements
December
31, 2004 and 2003
bear
a
reasonable interest rate as determined under policies established for the Plan
and (5) such other rules and regulations as may be adopted by the Company.
At
December 31, 2004 and 2003, the interest rates on participant loans ranged
from
4.25 percent to 11.00 percent and 4.25 percent to 11.62 percent, respectively.
In
conjunction with the amendment effective October 1, 2004 to allow for active
employees of Illinois Power Company to participate in the Plan, the Plan
accepted outstanding loan balances for employees of Illinois Power Company
electing an account rollover from October 1, 2004 through December 15,
2004.
Vesting
The
amounts in Participants’ accounts, including Company contributions, are fully
vested at all times.
Payment
of Benefits
The
total
amount of a Participant's account shall be distributed to the Participant
according to one of the options as described in the Plan document and as elected
by the Participant. A Participant whose account balance is $5,000 ($1,000
effective March 28, 2005) or greater may defer distribution until December
31 of
the year they attain age 70 1/2 but no later than April 1 of the year following
the Participant's attaining age 70 1/2. If the balance of the account is less
than $5,000 ($1,000 effective March 28, 2005), the distribution shall be made
in
a lump sum within ninety days of his or her termination of employment, provided
he or she is not an employee on such date. All distributions shall be in the
form of cash except that Participants may elect to have his or her interest
in
the Ameren Common Stock Fund or the AES Common Stock Fund, if applicable,
distributed in shares of Ameren or AES common stock, respectively. Participants
may withdraw certain basic contributions, rollover contributions and related
earnings thereon upon reaching age 59 1/2, in the event of total disability
or
financial hardship as defined by the Plan or the Code. For purposes of
distributions, the Participant's account value will be determined as of the
last
business day coincident with or immediately preceding the day of distribution.
Contributions to the Plan and investment income thereon are taxable to
Participants upon distribution pursuant to the rules provided for under the
Plan
and the Code.
The
Plan
also allows, at the discretion of the Company, participants of the former Union
Electric Company Employee Stock Ownership Plan and the former Ameren Corporation
Employee Stock Ownership Plan for Certain Employees of CIPS, to receive
distributions prior to termination of employment of (a) all or a portion of
a
Participant's account balance acquired at least 84 months prior to a
distribution and (b) any portion of a Participant's account balance acquired
by
dividends or other income.
Plan
Transfers In
For
2004,
Plan transfers in represent Participants’ account balances which have been
transferred from the Employees’ Savings Plan of Central Illinois Light Company
and the CILCORP Infraservices, Inc. 401(k) Plan into the Plan. For 2003, Plan
transfers in represent Participants’ account balances which have been
transferred from the Ameren Corporation Employee Long-Term Savings Plan - IUOE
NO. 148 and the Ameren Corporation Employee Long-Term Savings Plan - IBEW No.
702 into the Plan. The 2004 Plan transfers in were due to plan mergers. The
2003
Plan
Ameren
Corporation
Savings
Investment Plan
Notes
to Financial Statements
December
31, 2004 and 2003
transfers
in were due to participants transferring from a collective bargaining unit
to a
management position.
Plan
Termination
The
Company intends to continue the Plan indefinitely. However, the Company may
at
any time and for any reason, subject to ERISA and Internal Revenue Service
regulations, suspend or terminate the Plan provided that such action does not
retroactively adversely affect the rights of any Participant under the
Plan.
2.
Summary
of Significant Accounting Policies
Basis
of Accounting
The
accompanying financial statements of the Plan are prepared on the accrual basis
of accounting, except that benefit payments to Participants are recorded upon
distribution.
Use
of Estimates
The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date
of
the financial statements and the reported amounts of changes in net assets
available for benefits during the reporting period. Actual results could differ
from those estimates.
Investments
All
investments are presented at fair value as of December 31, 2004 and 2003. The
fair value of the Ameren Common Stock Fund and the AES Common Stock Fund were
determined using year-end published market prices. Investments in mutual funds
are valued at published net asset market value including accrued income on
the
last business day of each year. Investments in the Northern Trust Company
Collective Short-Term Investment Fund, the Northern Trust Company Collective
Stable Asset Fund, and the T. Rowe Price Stable Value Common Trust Fund
are
valued at cost plus accrued income, which approximates market value. Participant
loans are valued at cost, which approximates market value.
Investment
securities are exposed to various risks, such as interest rate, market, and
credit. Due to the level of risk associated with certain investment securities
and the level of uncertainty related to changes in the value of investment
securities, it is at least reasonably possible that changes in risks in the
near
term could materially affect the amounts reported in the Statement of Net Assets
Available for Benefits.
Income
Interest
income is recorded on the accrual basis. Dividend income is recorded on the
ex-dividend date. Gains and losses on security transactions are recorded on
the
trade date.
Administrative
Expenses
Trustee
fees and other fees associated with administering the Plan are paid by the
Plan.

Federal
Income Tax Status
The
Company obtained its latest determination letter July 31, 2001, in which the
Internal Revenue Service stated that the Plan was in compliance with the
applicable
requirements of
the
Code. The Plan has been amended since receiving the determination letter.
However, the Company believes that the Plan currently is
designed
and being operated in
compliance with the applicable requirements of the Code and, therefore, the
Plan
continues to qualify under Section 401(a) and

the
