                    ANNUAL REPORT OF AMEREN SERVICES COMPANY
                        For Year Ended December 31, 1999
                  Schedule XIV - Notes to Financial Statements

NOTE 1 - Summary of Significant Accounting Policies

Organization and Nature of Operations
Ameren  Services,  Inc.  (the  Company) is a  wholly-owned  subsidiary of Ameren
Corporation (Ameren), registered under the Public Utility Holding Company Act of
1935  (PUHCA).  The  Company  was  authorized  to conduct  business as a service
company for Ameren and its various  subsidiaries  by order of the Securities and
Exchange  Commission  (SEC) dated  December  31, 1997,  which  became  effective
January 1, 1998. The Company is organized along  functional  lines to accomplish
its purpose of providing  management,  administrative,  and technical  services.
These services are priced so that the Company operates on a break-even basis.

The Company  maintains its accounts in accordance with PUHCA, as administered by
the SEC, and has adopted a system of accounts consistent with that prescribed by
the Federal Energy Regulatory Commission. The accounting policies of the Company
conform to generally accepted accounting principles (GAAP).

Property and Plant
The cost of  additions  to, and  betterments  of, units of property and plant is
capitalized.  Cost includes  labor,  material,  applicable  taxes and overheads.
Maintenance  expenditures  and the  renewal  of items  not  considered  units of
property are charged to income as incurred.  When units of depreciable  property
are retired,  the original cost and removal cost,  less salvage,  are charged to
accumulated depreciation.

Depreciation
Depreciation  is provided  over the  estimated  lives of the various  classes of
depreciable property by applying composite rates on a straight-line basis.

Cash and Cash Equivalents
Cash  and  cash  equivalents  include  cash on hand  and  temporary  investments
purchased with an original maturity of three months or less.

Income Taxes
Ameren and its subsidiaries file a consolidated federal tax return. Deferred tax
assets and liabilities  are recognized for the tax  consequences of transactions
that have been  treated  differently  for  financial  reporting  and tax  return
purposes,  measured using statutory tax rates. The Company's expenses are billed
to the other  subsidiaries  of Ameren and taxes are computed on those  entities.
The Company had no deferred tax assets or  liabilities  at December 31, 1999 and
1998.

Use of Estimates
The  preparation  of  financial  statements  in  conformity  with GAAP  requires
management  to make  certain  estimates  and  assumptions.  Such  estimates  and
assumptions may affect 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 revenues and expenses during the reported period. Actual
results could differ from those estimates.

Fair Value of Financial Instruments
The  carrying  amounts of financial  instruments  on the  Company's  books are a
reasonable estimate of their fair value.


NOTE 2 - Common Stock

The Company is  authorized to issue 30,000 shares of common stock at a par value
of one cent ($.01) per share. Ameren holds all of the Company's common stock. At
December 31, 1999 and 1998, there were 1,000 shares outstanding.

NOTE 3 - Financing Arrangements

Ameren  has money pool  agreements  among its  subsidiaries  to  coordinate  and
provide for certain short-term cash and working capital requirements.  The money
pools are administered by the Company (see Note 4).

Ameren has a $300 million  short-term  bank credit  agreement  due in 2000 which
permits  Ameren  and its  subsidiaries  to  borrow or to  support  a portion  of
Ameren's commercial paper program. At December 31, 1999, all was unused and $240
million of such borrowing was available for the Company's use.

Ameren also has a $200  million  bank credit  agreement  due in 2002 that allows
Ameren  and its  subsidiaries  to borrow on a  long-term  basis or to  support a
portion of Ameren's commercial paper program. At December 31, 1999, $132 million
of such borrowing was available for the Company's use.


NOTE 4 - Related Party Transactions

The Company has  transactions in the normal course of business with other Ameren
subsidiaries. These transactions are primarily comprised of services received or
rendered.  Intercompany  receivables  were  approximately  $29  million  and $23
million,  respectively,  as of December 31, 1999 and 1998. Intercompany payables
totaled  approximately $7 million and $8 million,  respectively,  as of December
31, 1999 and 1998.

Ameren's subsidiaries have the ability to invest excess funds or borrow funds as
needed from  Ameren's  money pools.  Interest is  calculated at varying rates of
interest  depending on the  composition  of internal  and external  funds in the
money  pools.  Excess  funds that are not  borrowed  by other  subsidiaries  are
invested  externally by the Company and recorded as an intercompany note payable
on the Company's balance sheet.  Intercompany  notes payable were  approximately
$189 million and $2 million, respectively, as of December 31, 1999 and 1998.


NOTE 5 - Retirement Benefits

Ameren has a defined-benefit  retirement plan covering  substantially all of its
employees.   Benefits  are  based  on  the  employees'   years  of  service  and
compensation.   Ameren's  plans  are  funded  in  compliance   with  income  tax
regulations and federal funding requirements.

On  January 1, 1999,  the Union  Electric  Company  (AmerenUE)  and the  Central
Illinois Public Service Company  (AmerenCIPS) pension plans combined to form the
Ameren  Retirement  Plan.  The Ameren plan  covers  qualified  employees  of the
Company. The Company,  along with other subsidiaries of Ameren, is a participant
in the Ameren plan and is responsible for its proportional share of the costs of
the assets or liabilities. The Company's share of the pension costs for 1999 was
$3 million, of which approximately 26% was charged to construction accounts. The
AmerenUE  and  AmerenCIPS  pension  plans'  information  for  1998 is  presented
separately below.

AmerenUE's  plan  covers  qualified  employees  of  AmerenUE  as well as certain
employees of the Company.  Following is the pension plan information  related to
AmerenUE's plan as of December 31:

Pension costs for 1998 were $28 million of which  approximately  19% was charged
to construction accounts.

In addition to providing pension  benefits,  Ameren provides certain health care
and life insurance benefits for retired  employees.  Ameren accrues the expected
postretirement benefit costs during employees' years of service.

AmerenUE's  plans  cover  qualified  employees  of  AmerenUE  as well as certain
employees of the Company.  The  following is  information  related to AmerenUE's
postretirement benefit plans as of December 31:

AmerenUE's  funding policy is to annually  contribute the net periodic cost to a
Voluntary Employee Beneficiary Association trust (VEBA).  Postretirement benefit
costs were $46  million in 1999 and $43  million in 1998 of which  approximately
18% in 1999 and 17% in 1998 were charged to  construction  accounts.  AmerenUE's
transition  obligation at December 31, 1999, is being amortized over the next 13
years.

The MoPSC and the ICC allow the  recovery  of  postretirement  benefit  costs in
rates to the extent  that such costs are  funded.  In  December  1995,  AmerenUE
established  two external trust funds for retiree health care and life insurance
benefits. In 1999 and 1998, claims were paid out of the plan trust funds.

the accumulated  postretirement benefit obligation  approximately $4 million and
$31 million,  respectively.  AmerenCIPS' plans cover substantially all employees
of  AmerenCIPS  as well as certain  employees of the Company.  The  following is
information related to AmerenCIPS'  postretirement  benefit plans as of December
31:

AmerenCIPS'  funding  policy  is to fund the two VEBAs  and the  401(h)  account
established within the AmerenCIPS retirement income trust with the lesser of the
net periodic cost or the amount  deductible for federal income tax purposes.  In
1998,  AmerenCIPS  changed its measurement date for valuation of plan assets and
liabilities to December 31. Postretirement benefit costs were $3 million in 1999
and $6 million in 1998 of which  approximately  10% was charged to  construction
accounts in 1999 and 20% in 1998.  AmerenCIPS' transition obligation at December
31, 1999 is being amortized over the next 13 years.

The ICC allows the  recovery  of  postretirement  benefit  costs in rates to the
extent that such costs are funded.

Ultimate medical cost trend rate expected in year              2000      2000
- --------------------------------------------------------------------------------

A one  percentage  point increase in the medical cost trend rate is estimated to
increase  the net  periodic  cost  and the  accumulated  postretirement  benefit
obligation  approximately  $2  million  and  $20  million,  respectively.  A one
percentage  point  decrease  in the  medical  cost  trend rate is  estimated  to
decrease  the net  periodic  cost  and the  accumulated  postretirement  benefit
obligation approximately $2 million and $20 million, respectively.


NOTE 6 - Interchange Transactions

The Company acts as an agent for the  coordination  of interchange  transactions
with outside  parties.  Amounts related to these  transactions  are allocated to
AmerenUE and AmerenCIPS.


NOTE 7 - Contingency

Certain employees of the Company and its affiliated companies are represented by
the International Brotherhood of Electrical Workers (IBEW) and the International
Union of Operating  Engineers.  These employees  comprise  approximately  70% of
Ameren's workforce.  Labor agreements covering certain represented  employees of
the Company expired in 1999 and were renewed for a term expiring in 2002.  Labor
agreements  which  expired in 1999 have not been  renewed with IBEW Locals 1439,
309, 649 and 1455, who collectively  represent  approximately 2,000 AmerenUE and
Ameren  Services  Company  employees.  Negotiations  with  Local  1455 are still
ongoing.  However,  after engaging in extensive good-faith  bargaining with IBEW
Locals 1439, 309 and 649,  AmerenUE and the Company  submitted a last,  best and
final offer to these collective  bargaining units on February 2, 2000. The offer
was rejected and  AmerenUE and the Company  informed  these locals that it would
implement the  noneconomic  portion of its offer  effective  March 6, 2000.  The
employees are currently working under the noneconomic  portion of AmerenUE's and
the Company's last, best and final offer.  The Company is unable to predict what
further  action,  if any,  these  collective  bargaining  units will take or the
response  of the  Company's  union-represented  employees  to any  action by its
affiliates'  employees.  The Company is unable to determine what, if any, impact
these labor matters  could have on its future  financial  condition,  results of
operations or cash flows.
