CILCORP INC. AND CENTRAL ILLINOIS LIGHT COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1. Introduction

CILCORP Inc. (CILCORP or the Holding Company) is a wholly-owned subsidiary of The AES Corporation (AES). The consolidated financial statements include the accounts of CILCORP, Central Illinois Light Company (CILCO), QST Enterprises Inc. (QST) and its subsidiaries, QST Energy Inc. (QST Energy), and CILCORP Infraservices Inc. (CILCORP Infraservices), and CILCORP’s other subsidiaries (collectively, the Company), after elimination of significant intercompany transactions. The consolidated financial statements of CILCO include the accounts of CILCO and its subsidiaries, CILCO Exploration and Development Company, CILCO Energy Corporation, and Central Illinois Generation, Inc. CILCORP owns 100% of the common stock of its first-tier subsidiaries. In the fourth quarter of 1998, the operations of QST and its subsidiaries (excluding ESE Land Corporation and CILCORP Infraservices Inc. - see Management’s Discussion and Analysis) were discontinued and, therefore, are being reported as discontinued operations in the financial statements. Prior year amounts have been reclassified on a basis consistent with the 2002 presentation.

On April 29, 2002, The AES Corporation (AES) announced an agreement with Ameren Corporation to sell 100 percent of its ownership interest in CILCORP and its subsidiaries. The transaction is subject to regulatory approvals by the Illinois Commerce Commission (ICC), the Federal Energy Regulatory Commission (FERC), the Federal Communications Commission (FCC), the Securities and Exchange Commission (SEC), and expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act. AES expects the sale to close in the first quarter of 2003.

The accompanying unaudited consolidated financial statements have been prepared according to the rules and regulations of the SEC. Although the Company believes the disclosures are adequate to make the information presented not misleading, these consolidated financial statements should be read along with the Company’s 2001 Annual Report on Form 10-K.

In the Company’s opinion, the consolidated financial statements furnished reflect all normal and recurring adjustments necessary for a fair presentation of the results of operations for the periods presented. Operating results for interim periods are not necessarily indicative of operating results to be expected for the year or of the Company’s future financial condition.

NOTE 2. Contingencies

On May 11, 2001, CILCO and Enron Power Marketing, Inc. (EPMI), a subsidiary of Enron Corp. (Enron), entered into a new Master Agreement for electric purchases and sales, which covered energy transactions scheduled for deliveries during the period of 2001-2003. On November 30, 2001, CILCO notified EPMI that events of default had occurred under the Master Agreement and declared the Master Agreement terminated effective December 20, 2001. Due to contractual provisions and EPMI’s and Enron’s actions, management does not believe CILCO will be required to pay any amount to Enron or its affiliates and has therefore recorded no liability for undelivered electric purchases. Enron and EPMI filed Chapter 11 bankruptcy petitions on December 2, 2001, in the U. S. Bankruptcy Court for the Southern District of New York. Thereafter, CILCO purchased replacement power to serve its retail customers which had previously been partially supported by the EPMI transactions. While the ultimate outcome is unpredictable, management does not believe that EPMI’s

defaults under the Master Agreement, its filing for bankruptcy protection, CILCO’s termination of the Master Agreement, or CILCO’s purchase of replacement electricity will have a material adverse effect on CILCO’s financial position or results of operations.

On May 4, 2001, CILCO and Enron subsidiary Enron North America Corp. (ENA) entered into a natural gas transaction for daily deliveries not to exceed 10,000 MMBtu per day during calendar year 2002. CILCO has received no natural gas deliveries pursuant to this transaction. On October 24, 2001, CILCO and ENA entered into a short-term natural gas transaction giving CILCO the right to call upon ENA for the delivery of 10,000 MMBtu per day during the period from November 1, 2001, through March 31, 2002. Since late November 2001, ENA was unable to deliver natural gas when called upon by CILCO. ENA’s failure to deliver natural gas is an event of default under the Master Firm Sales Agreement governing the October transaction. On December 2, 2001, ENA filed a Chapter 11 bankruptcy petition in the U. S. Bankruptcy Court for the Southern District of New York. To the extent that it has been necessary, CILCO has purchased replacement natural gas. Because these transactions are part of a larger and more diversified natural gas supply portfolio and are subject to the Purchased Gas Adjustment clause, management does not believe ENA’s failure to supply natural gas or its subsequent bankruptcy filing will have a material adverse effect on CILCO’s financial position or results of operations.

NOTE 3. Accounting for Price Risk Management Activities

The Company utilizes commodity futures contracts, options and swaps in the normal course of its natural gas and electric business activities to reduce market or price risk. Since January 1, 2001, all derivative transactions have been accounted for under Statement of Financial Accounting Standards No. 133, “Accounting for Derivative Transactions and Hedging Activities” (SFAS 133), as interpreted and amended. SFAS 133 requires that an entity recognize all derivatives (including derivatives embedded in other contracts), as defined, as either assets or liabilities on the balance sheet and measure those instruments at fair value. Changes in the derivative’s fair value are to be recognized currently in earnings, unless specific hedge accounting criteria are met. All of the Company’s derivatives qualify as cash flow hedges. Under SFAS 133, the effective portion of the gain or loss on a derivative instrument designated and qualifying as a cash flow hedge is reported as a component of Other Comprehensive Income (OCI) until the hedged transaction affects earnings, at which time the amount accumulated in OCI is reclassified into earnings. In addition, under SFAS 133, any ineffective portion of the gain or loss is recognized in earnings immediately. All of the Company’s cash flow hedges are highly effective, and therefore, because any ineffectiveness is immaterial, all gains and losses have been recorded in OCI until the hedged transaction affects earnings. If a cash flow hedge is terminated because it is probable that the hedged transaction will not occur, the related balance in OCI as of such date is immediately recognized in earnings. If a cash flow hedge is terminated early for other reasons, the related balance in OCI as of the termination date is recognized in earnings concurrently with the related hedged transaction.

Gains/losses on derivatives that hedge non-regulated activities are reflected in operating results when the hedged commitments are recognized. The net gain reflected in operating results from derivative financial instruments for non-regulated activities for the quarter ended September 30, 2002, was $0.3 million for natural gas (included in Gas Purchased for Resale). The previously recorded gain/loss associated with these settled derivative financial instruments was removed from OCI. The open derivative positions are then marked-to-market through OCI. The net effect of these adjustments was to record an after-tax gain in OCI in the amount of $0.6 million for the quarter

ended September 30, 2002. The after-tax balance in OCI associated with these open derivative positions and unrealized gains on settled positions at September 30, 2002, was a gain of $0.9 million. The corresponding asset is reflected on the balance sheet in prepayments and other. The portion of OCI for open positions reflects hedges of natural gas sales of 2,280,000 MMBtu for commitments through February 2004. Approximately $0.9 million of OCI related to derivative financial instruments as of September 30, 2002, is expected to be recognized as an increase to operating earnings over the next twelve months based on market prices as of September 30, 2002. The actual amount recognized in earnings will be based on the market conditions at the time the derivatives are settled.

Beginning in March 2002, the Company is hedging its anticipated summer injections into storage fields utilizing collars (a combination of a put option and a call option) and futures to hedge the cost for customers charged the Purchased Gas Adjustment (PGA). In May 2002, the Company implemented a winter 2002-2003 hedging strategy related to regulated gas activities. This strategy also utilizes collars and futures to help protect customers from large price fluctuations. Gains and losses on PGA-related positions are being recorded as regulatory assets or liabilities in accordance with Statement of Financial Accounting Standards No. 71, “Accounting for the Effects of Certain Types of Regulation” (SFAS 71). For the quarter ended September 30, 2002, a mark-to-market gain of $0.9 million was recorded in the regulatory liability for all PGA-related derivatives, bringing the regulatory liability to $0.9 million. The corresponding asset is reflected on the balance sheet in prepayments and other. This reflects hedges of natural gas sales of 500,000 MMBtu for commitments through March 2003.

In December 2001, the Financial Accounting Standards Board (FASB) revised its earlier conclusion, Derivatives Implementation Group (DIG) Issue C-15, related to contracts involving the purchase or sale of electricity. Contracts for the purchase or sale of electricity, both forward and option contracts, including capacity contracts, may qualify for the normal purchases and sales exemption and are not required to be accounted for as derivatives under SFAS 133. In order for contracts to qualify for this exemption, they must meet certain criteria, which include the requirement for physical delivery of the electricity to be purchased or sold under the contract only in the normal course of business. Additionally, contracts that have a price based on an underlying that is not clearly and closely related to the electricity being sold or purchased or that are denominated in a currency that is foreign to the buyer or seller are not considered normal purchases and normal sales and are required to be accounted for as derivatives under SFAS 133. This revised conclusion was effective beginning April 1, 2002. The Company has determined that its physical contracts qualify for the normal purchases and sales exemption as redefined in DIG Issue C-15 and are not to be accounted for as derivatives under SFAS 133.

NOTE 5. Impact of Accounting Standards

In June 2001, the FASB issued Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets” (SFAS 142), and Statement of Financial Accounting Standards No. 143, “Accounting for Asset Retirement Obligations” (SFAS 143).

SFAS 142 requires that goodwill and intangible assets that have indefinite useful lives be tested at least annually for impairment rather than be amortized. The provisions of SFAS 142 were required to be applied starting with fiscal years beginning after December 15, 2001. The Company adopted SFAS 142 on January 1, 2002, and, as a result, annual goodwill amortization of approximately $15.3 million has ceased. Net income would have been $11.2 million and $19.8 million for the quarter and nine months ended September 30, 2001, respectively, had CILCORP discontinued the amortization of goodwill effective January 1, 2001. The initial impairment assessment has been performed, utilizing the requirements of SFAS 142, and the Company has determined that its fair value exceeds its carrying value and therefore, goodwill for the Company is considered not impaired. The Company has identified the following four reporting units under the provisions of SFAS 142: CILCO Electric, CILCO Gas, CILCO Other and Other Businesses. The Company has completed the allocation of goodwill to the reporting units as follows:

	CILCO Electric		CILCO Gas		CILCO Other		Other Businesses		Total
	CILCO Electric		CILCO Gas		CILCO Other		Other Businesses		Total
	(In thousands)
	(Unaudited)

Goodwill, net of accumulated amortization of $33,753, as of December 31, 2001	$	350,256	$	132,514	$	2,118	$	94,323	$	579,211

SFAS 143 addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. SFAS 143 is effective for financial statements issued for fiscal years beginning after June 15, 2002. The Company has not yet quantified the effect, if any, of this new standard on the consolidated financial statements.

Statement of Financial Accounting Standards No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (SFAS 144), was issued in August 2001, and is effective for financial statements issued for fiscal years beginning after December 15, 2001, and interim periods within those fiscal years. SFAS 144 addresses financial accounting and reporting for the impairment or disposal of long-lived assets. The adoption of SFAS 144 has not had a significant impact on the Company’s financial position or results of operations.

Statement of Financial Accounting Standards No. 145, “Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections” (SFAS 145), was issued in April 2002. The provisions of SFAS 145 related to the rescission of FASB Statement No. 4 shall be applied in fiscal years beginning after May 15, 2002. All other provisions of this Statement are effective for financial statements issued on or after May 15, 2002. Management has determined that adoption of SFAS 145 has no material effect on the Company’s consolidated financial statements.

In June 2002, the FASB issued Statement of Financial Accounting Standards No. 146, “Accounting for Costs Associated with Exit or Disposal Activities” (SFAS 146). The provisions of SFAS 146 are effective for exit or disposal activities that are initiated after December 31, 2002. The Company has not yet quantified the effect, if any, of this new standard on the consolidated financial statements.

Emerging Issues Task Force (EITF) Issue No. 02-03 - Issues Involved in Accounting for Contracts Under EITF Issue No. 98-10, “Accounting for Contracts Involved in Energy Trading and Risk Management Activities” (EITF 02-03). In June 2002, the EITF reached a consensus on Issue 1 of EITF 02-03 (consensus). The key requirements are that all gains and losses on energy trading contracts and related physical transactions must be shown net in the income statement. The gross transaction volumes for those energy trading contracts that are physically settled must be disclosed in the notes to the financial statements. The consensus is effective for financial statements issued for periods ending after July 15, 2002.

The Company currently accounts for all its non-regulated power and gas marketing activities at gross in the Consolidated Statements of Income. The Company has reviewed all its current power and gas marketing contracts and all contracts closed in prior periods and identified no trading contracts subject to EITF 02-03 or EITF Issue No. 98-10, “Accounting for Contracts Involved in Energy Trading and Risk Management Activities”.

NOTE 6. Additional Minimum Pension Liability

At December 31 of each year, the Company reviews each pension plan to determine if the plans’ accumulated benefit obligations exceed the fair value of the plan assets. If the accumulated benefit obligations exceed the fair value of the plan assets, an additional minimum pension liability is recorded on the balance sheet, with a corresponding charge to other comprehensive income. Downturns in the stock market affect the value of the pension assets, and accordingly, the additional minimum pension liability at December 31, 2002, may be a material amount.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

CILCORP Inc. (CILCORP) is a wholly-owned subsidiary of The AES Corporation (AES). The financial condition and operating results of CILCORP and its subsidiaries (the Company) primarily reflect the operations of subsidiary Central Illinois Light Company (CILCO).

In July 2000, AES announced plans to acquire IPALCO Enterprises, Inc. (IPALCO), a utility holding company headquartered in Indianapolis, Indiana. Following this announcement, AES indicated that as part of the Securities and Exchange Commission (SEC) approval process for the IPALCO transaction, AES expected to restructure its ownership interests in CILCORP within a specified period of time in order to continue as an exempt holding company under the Public Utility Holding Company Act of 1935 (PUHCA). On March 23, 2001, AES received an order from the SEC which allowed AES’ continued exemption from PUHCA. The exemption order required AES to divest its ownership interests in CILCO’s regulated utility assets within two years of the closing (March 27, 2001) of AES’ acquisition of IPALCO. On April 29, 2002, AES announced an agreement with Ameren Corporation to sell 100 percent of its ownership interest in CILCORP and its subsidiaries. The transaction is subject to regulatory approvals by the Illinois Commerce Commission (ICC), the Federal Energy Regulatory Commission (FERC), the Federal Communications Commission (FCC), the SEC, and expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act. AES expects the sale to close in the first quarter of 2003.

The Other Businesses segment includes the operations of the Holding Company itself (Holding Company), its investment subsidiary, CILCORP Investment Management Inc. (CIM), CILCORP Ventures Inc. (CVI), and CILCORP Infraservices Inc., which provides utility infrastructure operation and maintenance services. The results of QST and its subsidiaries (excluding ESE Land Corporation and CILCORP Infraservices Inc.) are reported as discontinued operations (see Results of Operations - QST Enterprises Discontinued Operations).

Forward-Looking Information

Forward-looking information is included in Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A). Certain material contingencies are also described in Note 2 to the Consolidated Financial Statements.

Some important factors could cause actual results or outcomes to differ materially from those expressed or implied in MD&A. The business and profitability of CILCORP and its subsidiaries are influenced by economic and geographic factors, including ongoing changes in environmental laws and weather conditions; the extent and pace of development of competition for retail and wholesale energy customers; changes in technology; changes in company-wide operation and plant availability compared to historical performance and changes in historical operating cost structure, including changes in various costs and expenses; pricing and transportation of commodities; market supply and demand for energy and energy derivative financial instruments; inflation; capital market conditions; and environmental protection and compliance costs. Prevailing governmental policies, statutory changes, and regulatory actions with respect to rates, tariffs, industry structure and recovery of various costs incurred by CILCO in the course of its business and increasing wholesale and retail competition in the electric and gas business affect its earnings. In addition, actual results or outcomes could differ materially from those expressed or implied in MD&A due to the announced transaction, concluded or not, by CILCORP’s sole

shareholder, The AES Corporation, to sell its ownership interest in CILCORP and its subsidiaries to Ameren Corporation. All such factors are difficult to predict, contain uncertainties that may materially affect actual results and, to a significant degree, are beyond the control of CILCORP and its subsidiaries. CILCORP and its subsidiaries undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of changes in actual results, assumptions or other factors.

Capital Resources & Liquidity

The Company believes that internal and external sources of capital which are or are expected to be available will be adequate to fund its capital expenditures, pay its financial obligations, meet working capital needs and retire or refinance debt as it matures.

CILCORP

CILCORP (the Holding Company) is currently authorized by its Board of Directors to borrow up to $60 million on a short-term basis. At September 30, 2002, the Holding Company had no short-term debt outstanding.

In October 1999, the Holding Company issued $225 million of 8.7% senior notes (due 2009) and $250 million of 9.375% senior notes (due 2029). Along with equity funds provided by AES, the proceeds of the notes were used by AES to acquire all outstanding shares of CILCORP common stock for approximately $886 million, to pay transaction costs related to the acquisition, and to retire short-term debt.

CILCO

Capital expenditures totaled $96.1 million for the nine months ended September 30, 2002. Capital expenditures are anticipated to be approximately $38.9 million for the remainder of 2002 and are currently estimated to be approximately $80.2 million in 2003. The increase in capital expenditures in 2002 and 2003 over 2001 relates primarily to the installation of nitrogen oxide (NOx) reduction equipment at the Edwards and Duck Creek generating stations.

CILCO is currently authorized by its Board of Directors to issue up to $150 million of short–term debt, but had no short-term debt at September 30, 2002. At September 30, 2002, committed bank lines of credit totaled $90 million, all of which were unused. A $30 million bank line expires in the fourth quarter of 2002, with the remaining lines expiring in 2003. CILCO has not determined if it will renew or replace the $30 million bank line. CILCO plans to finance its 2002 and 2003 capital expenditures with funds provided by operations, short-term debt and long-term debt. In June 2002, CILCO obtained a two-year $100 million senior secured term loan. The proceeds of the borrowings were used to reduce short-term debt, and will be used to refund medium-term notes maturing in 2003 and for general corporate purposes. The

loan is secured by a first mortgage on substantially all of CILCO’s property and has a variable interest rate. The average interest rate on this term loan is currently 2.98%. Future funds provided by operations may be affected by the deregulation of the electric and natural gas utility industries (see Competition).

CIM

At September 30, 2002, CIM had outstanding debt of $12.6 million, borrowed from CILCORP.

CVI

At September 30, 2002, CVI had outstanding debt of $4.8 million, borrowed from CILCORP.

Competition

CILCO, as a regulated public utility, has an obligation to provide electricity and natural gas to retail customers within its defined service territory; thus, CILCO has not generally been in competition with other energy suppliers for retail electric or gas customers in these areas. However, the passage of the Electric Service Customer Choice and Rate Relief Law of 1997 (Customer Choice Law) began a transition process to a fully competitive retail market for electricity in Illinois. During the mandatory transition period, electric utilities are prohibited from increasing base rates, unless the electric utility demonstrates that its 2-year average earned rate of return is below the 2-year average of the monthly average yield of the U.S. Treasury long-term bond index. The initial mandatory transition period ends on January 1, 2005. Recently enacted legislation extends this rate freeze and transition period to January 1, 2007. For CILCO, this extension is applicable, provided that Ameren Corporation’s acquisition of CILCORP and its subsidiaries closes. Electricity and natural gas also compete with other forms and sources of energy available to customers. For example, within the City of Springfield, CILCO’s natural gas business competes with the City’s municipal electric system to provide customer energy needs.

Primarily as a result of the Customer Choice Law, the electric industry in Illinois will change significantly during the coming years at both the wholesale and retail levels. As of December 31, 2000, all non-residential customers had the ability to choose their electric supplier. Residential electric customers were able to choose their electric supplier as of May 1, 2002.

If a customer chooses to leave its present electricity supplier, that utility will collect a fee for delivering power and may assess an additional transition charge on the customer. This collection methodology must be filed with and approved by the Illinois Commerce Commission (ICC) and is designed to help utilities recover a portion of the costs of past investments made under a regulated system. The transition charge will usually reduce a customer’s economic incentive to switch suppliers. Transition charges may be collected through 2006 (2008 upon the ICC’s finding that a utility’s financial condition is impaired and the utility meets other requirements specified in the Customer Choice Law).

On March 9, 2000, CILCO filed revised tariff sheets with the ICC eliminating the collection of the customer transition charge effective March 17, 2000. At a March 15, 2000, hearing, the ICC approved CILCO’s revised tariffs, thereby

eliminating the collection of any customer transition charge. CILCO cannot re-establish the collection of a transition charge until it files, and the ICC approves, revised tariff sheets that reinstate a transition charge.

The Customer Choice Law also requires electric base rate reductions that vary by utility. CILCO reduced its residential base rates by 2% in August 1998, by 2% in October 2000, and by an additional 1% in October 2002. Also, CILCO’s return on common equity will, in general, be capped (the Equity Cap) at an index (a 12-month average yield for long-term U.S. Treasury bonds plus 8% for calendar years 1998 and 1999 and a 12 month-average yield for long-term U.S. Treasury bonds plus 9% for calendar years 2000 through 2004) plus 1.5 percentage points. The Equity Cap was 16.1% in 2001, 16.6% in 2000, and 15.1% in 1999. If CILCO’s two-year average return on common equity exceeds the two-year average of the Equity Cap, fifty percent of the earnings in excess of the average Equity Cap must be refunded to customers in the following year.

On June 30, 1999, Senate Bill 24 (a clarification and technical correction of the Customer Choice Law) was signed into law. This law allows certain utilities, including CILCO, to increase the Equity Cap by an additional 2% over the Equity Cap provided under the Customer Choice Law, for the period 2000 through 2004. The increase in the Equity Cap is allowed in exchange for these utilities offering choice of electricity suppliers to selected manufacturing customers on June 1, 2000, and to the remaining manufacturing customers on October 1, 2000, earlier than previously allowed under the Customer Choice Law. Utilities selecting this option must also waive the right to seek a two-year extension on the collection of transition charges. On April 13, 2000, CILCO filed revised tariff sheets with the ICC to make these selected customers eligible for choice on June 1, 2000, in order to increase the equity cap by 2%, as outlined in Senate Bill 24.

With the enactment of the Customer Choice Law, electric generation in Illinois became deregulated and competitive. As a result, the accounting principles applicable to rate-regulated enterprises (Statement of Financial Accounting Standards No. 71, “Accounting for the Effects of Certain Types of Regulation” (SFAS 71)) no longer apply to the electric generation portion of CILCO’s business. There were no impairments to CILCO assets as a result of transitioning from SFAS 71. Its ability to keep total production costs competitive in a deregulated market will determine whether and to what extent the value of these assets may be impaired in the future.

With electric choice beginning on October 1, 1999, for its industrial customers and some of its commercial customers, and with all other non-residential customers being able to choose their electric supplier on December 31, 2000, CILCO has entered into multi-year contracts with targeted customers representing approximately 45% of total 2001 electric kWh sales to non-residential customers. These contracts, most of which expire in 2004, were designed to capture a significant portion of the margin that the customers paid to CILCO in the most recent twelve months. In 2002, CILCO has been negotiating new contracts with targeted at-risk customers who are currently being served under bundled tariff rates. For those contracts expiring in 2002, CILCO has been negotiating contract extensions with selected customers.

The ultimate market price for electricity, the cost for a utility to produce or buy electricity, and the number of customers that may be gained or lost due to customer choice of supplier in Illinois cannot be predicted. As a result, management cannot predict the ultimate impact that the Customer Choice Law will have on CILCORP’s financial position or results of operation, but the effect could be significant. However, CILCO is currently a low-cost provider of electricity, and management will continue to position CILCO for competition by controlling costs, maintaining good customer relations, and developing

flexibility to meet individual customer requirements. As of September 30, 2002, all electric customers eligible for choice continue to purchase their electricity supply from CILCO, other than those who self-generate. As of September 30, 2002, CILCO has contracts totaling approximately 2.6 million megawatt hours of retail load outside of its service territory for 2002. CILCO will supply these new customers by primarily purchasing electricity from other suppliers. CILCO has made the necessary firm supply and transmission arrangements to meet customer requirements.

Electric gross margin increased 57% for the quarter and 19% for the nine months ended September 30, 2002, compared to the same periods in 2001, primarily as a result of a Fuel Adjustment Clause (FAC) settlement agreement in the third quarter of 2001 between the Company and the Illinois Commerce Commission (ICC). In its order dated August 21, 2001, the ICC approved the agreement requiring the Company to refund $17.8 million related to the 1999 FAC reconciliation and $2.6 million related to the 2000 FAC reconciliation. Increased residential sales also contributed to the increase in electric gross margin for the quarter and nine months ended September 30, 2002. In the first quarter of 2002, CILCO also received a payment discount in conjunction with

the termination of an out-of-market long-term coal contract. The discount reduced cost of fuel by $0.8 million for the first quarter of 2002. On December 20, 2000, as part of the 1999 FAC reconciliation hearings, the ICC ordered changes in CILCO’s calculation of allowable fuel costs applicable to sales subject to the FAC. These changes revised the allocation of generated and purchased power between regulated and non-regulated sales. As a result of this order, the regulated sales margin decreased and the non-regulated sales margin increased for January through March 2001. On March 9, 2001, the ICC issued an emergency rule in response to the margin shifts. The emergency rule restored the previous calculation method for off-system non-regulated sales. On July 25, 2001, the ICC entered a final order, amending the emergency rule by changing the method for allocating fuel costs to non-regulated sales within CILCO’s service territory.

Retail sales volumes increased 7% for the quarter and 2% for the nine months ended September 30, 2002, compared to the same periods in 2001. Residential sales increased 13% for the quarter and 7% for the nine months ended September 30, 2002, compared to the same periods in 2001. Commercial sales increased 6% for the quarter and 2% for the nine months ended September 30, 2002, compared to the same periods in 2001. Industrial sales increased 2% for the quarter and decreased 2% for the nine months ended September 30, 2002, compared to the same periods in 2001. Cooling degree days were 22% higher for the quarter and nine months ended September 30, 2002, compared to the same periods in 2001.

Sales for resale decreased 33% for the quarter and 42% for the nine months ended September 30, 2002, compared to the same periods in 2001. Sales for resale vary based on the energy requirements of native load customers, neighboring utilities and power marketers, CILCO’s available capacity for bulk power sales and the price of power available for sale.

The overall level of business activity in CILCO’s service territory and weather conditions are expected to continue to be the primary factors affecting electric sales in the near term. CILCO’s electric sales will also be affected in the long term by deregulation and increased competition in the electric utility industry.

The cost of fuel decreased 48% for the quarter and 31% for the nine months ended September 30, 2002, compared to the same periods in 2001, primarily due to the FAC settlement with the ICC in 2001. Additionally, CILCO renegotiated a long-term coal supply contract in late 2001 which resulted in lower coal costs in 2002. Purchased power increased 6% and 15% for the quarter and nine months ended September 30, 2002, respectively, compared to the same periods in 2001.

Electric operation and maintenance expense increased 6% for the quarter and 5% for the nine months ended September 30, 2002, compared to the same periods in 2001. The increase was mainly due to increased costs for pension, other post-employment benefits and tree trimming, partially offset by lower uncollectible accounts expense. Also contributing to the unfavorable variance for the nine months ended September 30, 2002, were expenses incurred as the result of an ice storm in the first quarter of 2002.

Fixed charges and other expenses decreased 5% for the quarter and 13% for the nine months ended September 30, 2002, compared to the same periods in 2001, primarily due to decreased short-term borrowings and increased capitalized interest related to NOx reduction projects at the power plants.

Income tax expense increased for the quarter and for the nine months ended September 30, 2002, compared to the same periods in 2001, due to increases in income before income taxes.

CILCO Gas Operations

Gas gross margin increased 6% for the quarter and decreased 1% for the nine months ended September 30, 2002, compared to the same periods in 2001. Residential sales volumes increased 2% for the quarter and decreased 1% for the nine months ended September 30, 2002, compared to the same periods in 2001. Commercial sales volumes increased 6% for the quarter and decreased 7% for the nine months ended September 30, 2002, compared to the same periods in 2001. Heating degree days were 8% lower for the nine months ended September 30, 2002, compared to the same period in 2001. Industrial sales volumes decreased 14% for the quarter and for the nine months ended September 30, 2002, compared to the same periods in 2001.

The overall level of business activity in CILCO’s service territory and weather conditions are expected to continue to be the primary factors

affecting gas sales in the near term. CILCO’s gas sales may also be affected by further deregulation at the retail level in the natural gas industry.

Revenue from gas transportation services remained relatively constant for the quarter and increased 10% for the nine months ended September 30, 2002, while gas transportation sales volumes increased 5% for the quarter and 17% for the nine months ended September 30, 2002, compared to the same periods in 2001.

The cost of gas increased 23% for the quarter and decreased 48% for the nine months ended September 30, 2002, compared to the same periods in 2001, primarily due to fluctuations in natural gas prices. These costs were passed through to customers via the Purchased Gas Adjustment (PGA).

Gas operation and maintenance expense increased 1% for the quarter and 8% for the nine months ended September 30, 2002, compared to the same periods in 2001. The increases were primarily due to increases in expenses for public liability claims, pension and other post-employment benefits, partially offset by decreased uncollectible accounts expense.

Fixed charges and other expenses decreased 6% for the quarter and 12% for the nine months ended September 30, 2002, compared to the same periods in 2001, mainly due to decreased short-term borrowings.

Income tax expense decreased for the nine months ended September 30, 2002, compared to the same period in 2001, due to a decrease in income before income taxes.

CILCO Other Operations

The following table summarizes CILCO’s Other income and deductions for the three months and nine months ended September 30, 2002 and 2001.

Other income	$	7,884		$	920		$	11,526		$	4,508

Gross margin increased $12.2 million for the quarter and $13.6 million for the nine months ended September 30, 2002, compared to the same periods in 2001, primarily due to increased margin per MWh sold and to increased non-regulated electricity sales in Illinois outside of CILCO’s service territory. The higher margin per MWh sold is not expected to continue beyond third quarter 2002 operating results. These sales of electricity were to customers eligible to choose their energy supplier under the Customer Choice Law.

Operating expenses increased for the quarter and nine months ended September 30, 2002, compared to the same periods in 2001, primarily due to increased administrative and bad debt expenses for non-regulated sales.

Proceeds from company-owned life insurance in the third quarter of 2002 reduced other deductions by approximately $0.5 million for the quarter and nine months ended September 30, 2002, compared to the same periods in 2001.

Other Businesses Operations

The following table summarizes Other Businesses revenue and expenses for the three months and nine months ended September 30, 2002 and 2001. Other Businesses results include income earned and expenses incurred at the Holding Company, CIM, CVI, and CILCORP Infraservices Inc.

Other Businesses income (loss)	$	(5,320	)	$	7,013		$	(16,544	)	$	(10,898	)

Gas marketing revenue increased 13% for the quarter and 20% for the nine months ended September 30, 2002, while gas purchased for resale increased 6% for the quarter and 17% for the nine months ended September 30, 2002, compared to the same periods in 2001. These increases were due to increased gas marketing sales at CVI subsidiary CILCORP Energy Services Inc.

Other revenue decreased 102% for the three months ended and 89% for the nine months ended September 30, 2002, compared to the same periods in 2001, due primarily to a $4.5 million settlement in the third quarter of 2001 of a preacquisition contingency related to litigation at QST Energy. See related discussion at Results of Operations - QST Enterprises Discontinued Operations.

Fuel for generation and purchased power was impacted by the settlement of a preacquisition contingency in 2001. In September 2001, CILCORP recorded an $18 million reduction in a preacquisition contingency related to an out-of-market coal contract with a corresponding reduction in cost of fuel. The adjustment to this liability was necessitated by a change in the Company’s plan relative to this contract. Accordingly, the company made a new assessment of the potential liability and recorded an adjustment to the original liability. Fuel for generation and purchased power was also

impacted in 2001 by $4.0 million in amortization related to the preacquisition liability for this out-of-market coal contract. This contract was settled during the fourth quarter of 2001 and the preacquisition contingency related to this contract was removed.

Depreciation and amortization decreased during the quarter and nine months ended September 30, 2002, following the Company’s adoption of Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets” (SFAS 142) in January 2002. SFAS 142 requires that goodwill and intangible assets that have indefinite useful lives be tested at least annually for impairment rather than be amortized. Accordingly, the Company has ceased goodwill amortization which was approximately $11.5 million during the nine months ended 2001. See related discussion in Note 5 to the Consolidated Financial Statements.

Interest expense decreased 6% for the quarter and nine months ended September 30, 2002, compared to the same periods in 2001, mainly due to the retirement of CILCORP’s medium-term notes in 2001 and to lower short-term debt in 2002. This decrease was partially offset by interest on deferred compensation arrangements for two former officers that was recorded during the second quarter of 2002.

The income tax benefit increased significantly during the quarter and nine months ended September 30, 2002, compared to the same periods in 2001, due to lower income before income taxes.

QST Enterprises Discontinued Operations

QST Enterprises and QST Energy ceased operations during the fourth quarter of 1998, except for fulfillment of contractual commitments for 1999 and beyond. Accordingly, the results of QST Enterprises are reported as discontinued operations. An initial loss provision was recorded for the discontinued energy operations in 1998. Subsequent purchase accounting adjustments included additional discontinued operations loss accruals for QST Enterprises.

Loss from operations of discontinued businesses, net of tax:

QST Enterprises’ financial results for all periods shown were in excess of the discontinued operations provision and are shown as losses for those periods. Beginning in 1999, QST Energy was involved in litigation against two of its California commercial customers. On July 19, 2001, QST Energy and the two customers signed a settlement agreement and mutual release which resolved all of the pending lawsuits. A cash settlement of $6 million was paid to QST Energy and applied against the accounts receivable balance at QST Energy, which was $13 million at the time of settlement. CILCORP had reserved $4.5 million as a preacquisition contingency related to this litigation. The remaining receivable of $7.0 million at QST Energy was written off during the third quarter of 2001, and was partially offset by the $4.5 million gain recorded at CILCORP.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market Risk Sensitive Instruments

CILCORP and its subsidiaries (the Company) are exposed to non-trading risks through its daily business activities. These non-trading activities may include the market or commodity price risk related to CILCO’s retail tariff activity and the Company’s non-regulated commodity marketing activities.

The majority of the Company’s electricity sales during the third quarter of 2002 were to CILCO retail customers in Illinois under tariffs regulated by the Illinois Commerce Commission (ICC). Gas costs, prudently incurred in connection with sales to customers under tariffs regulated by the ICC, are recovered through the Company’s Purchased Gas Adjustment (PGA). Prior to October 29, 2001, prudently incurred costs of fuel used to generate electricity and purchased power costs were recovered from retail customers that purchase energy through regulated tariffs under the Fuel Adjustment Clause (FAC). Thus, through October 28, 2001, there had been very limited commodity price risk associated with CILCO’s traditional regulated sales. CILCO filed to eliminate the FAC on September 10, 2001. The ICC approved the elimination of the FAC on October 24, 2001, for bills issued on or after October 29, 2001. While the Company is exposed to increased commodity price risk due to the elimination of the FAC, sufficient supply has been placed under contract to limit the Company’s exposure to market risk at any given time. When this supply is added to CILCO generation capacity, a reserve margin of over 10% is experienced, based on a peak load of 1,270 MW during the summer cooling season. Since CILCO supplies over 90% of its native load with its generation capacity, generation can be adjusted on a real-time basis to match actual load at any given time. CILCO is subject to the risk that generation becomes unavailable due to forced outages. The Company’s historical unplanned outage rate is 5.1%. In the event that CILCO generation and purchased supply is insufficient to meet load requirements, CILCO would have to purchase electric supply from the market at prevailing market rates.

The market risk inherent in the non-regulated activities of CILCORP and its subsidiaries is the potential loss arising from adverse changes in natural gas and electric commodity prices relative to the physical and financial positions that the Company maintains. The prices of natural gas and electricity are subject to fluctuations resulting from changes in supply and demand. The Company is engaged in non-regulated electric retail and natural gas sales in Illinois, including wholesale power purchases and sales to utilize its electric generating capability. At September 30, 2002, these non-regulated activities had net open market price risk positions of approximately 289,000 MWh of electricity and 220,000 Mcf of natural gas. A market price sensitivity of 10% applied to positions open in the next twelve months is not material to the Company. See Note 3 for a discussion of the Company’s use of financial derivatives for hedging purposes. Due to the high correlation between the changes in the value of the financial instrument positions held by the Company and the change in price of the underlying commodity, the net effect on the Company’s net income resulting from the change in value of these financial instruments is not expected to be material.

Item 4. Controls and Procedures

Changes in Internal Controls. There were no significant changes in our internal controls or, to our knowledge, in other factors that could significantly affect such controls subsequent to the Evaluation Date.
