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, 2007 and
2006, 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 schedules of
assets (held at end of year) and reportable transactions are presented for the
purpose of additional analysis and are not a required part of the basic
financial statements but are 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. Those
supplemental schedules are the responsibility of the Plan’s
management. The supplemental schedules have been subjected to the
auditing procedures applied in the audits of the basic financial statements and,
in our opinion, are 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
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 Ameren Corporation (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. See Note 8 – Subsequent
Events, which discusses the merger of the Ameren Corporation Employee Long-Term
Savings Plan – IBEW No. 702 (Long-Term Savings Plan) into the Plan on February
1, 2008.
Participation
The Plan
covers substantially all employees of the Company, except contract employees
covered by a collective bargaining agreement between the Company and employees
who are members of the IBEW No. 702 collective bargaining unit employed by
Central Illinois Public Service or Ameren Energy Generating
Company. All regular full time employees are eligible to participate
upon employment. See Note 8 – Subsequent Events, for information
related to the termination of the Long-Term Savings Plan.
Contributions
All
Participants can contribute a maximum of 100 percent of their base compensation
to the Plan. Participant contributions are subject to annual
limitations imposed by the Code ($15,500 in 2007 and $15,000 in
2006). 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. Through October 5,
2006, the Employer Additional Matching Contributions were invested in the Ameren
Common Stock Fund, with the amounts remaining invested in the Ameren Common
Stock Fund until Participants reached age 55. At age 55, Participants
had the opportunity to allocate these contributions to different investments if
so desired. Beginning October 6, 2006, the Employer Additional
Matching Contributions continue to be invested in the Ameren Common Stock Fund,
but participants have the opportunity to immediately allocate these
contributions to different investments if so desired. All

Corporation
Savings

Notes

December

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 $5,000 in 2007 and $5,000 in 2006 as a “catch-up”
contribution. The Company does not match “catch-up” contributions.
Participants
direct their contributions and the Employer 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,
excluding the AES Common Stock Fund. Such fund allocation elections
may be changed daily. Investments in the AES Common Stock Fund can be
reallocated at any time, but no new investments can be allocated to this
fund. 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 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, 2007 and 2006, the
interest rates on participant loans ranged from 4.00 percent to 10.50
percent.
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 $1,000 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 $1,000, 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.

December

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 AmerenCIPS, 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. Any such distributions would be subject to
tax withholding and potentially a 10 percent early withdrawal penalty similar to
any other early Plan distribution unless the distribution is rolled over to an
individual retirement account or other qualified plan.
Plan
Transfers In
For 2006,
Plan transfers in represent Participants’ account balances which have been
transferred into the Plan from the Long-Term Savings Plan. These Plan
transfers in were due to participants transferring from a collective bargaining
unit to a management position or other non-IBEW No. 702 collective bargaining
unit.
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.

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.
The
Company adopted the provisions of Financial Accounting Standards Board Staff
Position AAG INV-1 and SOP 94-4-1, Reporting of Fully Benefit
Responsive Investment Contracts Held by Certain Investment Companies Subject to
the AICPA Investment Company Guide and Defined-Contribution Health and Welfare
and Pension Plans (the "FSP") as of the plan year ended December 31,
2006. The FSP requires investment contracts held by
defined-contribution plans to be reported at fair value. Previously,
the Plan had reported fully benefit responsive investment contracts at contract
value which represents the amount contractually available for participant
benefits under the investment contract. As required by the FSP, the
Statement of Net Assets Available for Benefits presents the fair value of the
investment contracts as a component of investments. The difference
between the fair value of the investment contracts and the contract value is
presented as the "Adjustment from fair value to contract value for fully
benefit-responsive
Ameren
Corporation
Savings
Investment Plan
Notes
to Financial Statements
December
31, 2007 and 2006
investment
contracts" in the Statement of Net Assets Available for Benefits. The
adoption of the FSP did not impact the Statement of Changes in Net Assets
Available for Benefits.
Investments
All
investments are presented at fair value as of December 31, 2007 and
2006. 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 are valued at cost plus accrued income, which approximates fair
value. Investments in the Northern Trust Company Collective Stable
Asset Fund are presented at fair value and adjusted to contract value to
represent benefits available to Plan participants. Participant loans
are valued at cost, which approximates fair 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.
Recent
Accounting Pronouncements
In
September 2006, the FASB issued Statement of Financial Accounting Standards No.
157, Fair Value
Measurements ("SFAS 157"), which defines fair value, establishes a
framework for measuring fair value, and expands disclosures about fair value
measurements. SFAS 157 clarifies that fair value is a market based
measurement that should be determined based on the assumption that market
participants would use in pricing an asset or liability. This
standard is effective for the Plan for the 2008 fiscal year. We are
still in the process of determining the impact of the adoption of SFAS 157 will
have, if any; however, at this time we do not expect the impact of adoption to
be material.

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. Effective January 31, 2007, the
Company has filed for re-qualification of the Plan with the Internal Revenue
Service. 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 related trust continues to be
tax-exempt as of December 31, 2007. Therefore, no provision for
income taxes has been included in the Plan’s financial statements.
