FORWARD-LOOKING STATEMENTS

Statements in this report not based on historical facts are considered “forward-looking” and, accordingly, involve risks and uncertainties that could cause actual results to differ materially from those discussed. Although such forward-looking statements have been made in good faith and are based on reasonable assumptions, there is no assurance that the expected results will be achieved. These statements include (without limitation) statements as to future expectations, beliefs, plans, strategies, objectives, events, conditions, and financial performance.

PART I

 

ITEM 1. BUSINESS.

GENERAL

 

Ameren, headquartered in St. Louis, Missouri, is a public utility holding company under PUHCA 2005 administered by FERC. Ameren was formed in 1997 by the merger of UE and CIPSCO. Ameren acquired CILCORP in 2003 and IP in 2004. Ameren’s primary assets are the common stock of its subsidiaries, including UE, CIPS, Genco, CILCORP and IP.

Ameren’s subsidiaries are separate, independent legal entities with separate businesses, assets and liabilities. These subsidiaries operate rate-regulated electric generation, transmission and distribution businesses, rate-regulated natural gas transmission and distribution businesses, and non-rate-regulated electric generation businesses in Missouri and Illinois. Dividends on Ameren’s common stock are dependent on distributions made to it by its subsidiaries.

 

The following table presents our total employees at December 31, 2008:

 

Ameren(a)

   9,524

UE

   4,146

CIPS

   679

Genco

   577

CILCORP/CILCO

   626

IP

   1,173

 

(a) Total for Ameren includes Ameren registrant and nonregistrant subsidiaries.

As of January 1, 2009, the IBEW, the IUOE, the NCF&O and the Laborers and Gas Fitters labor unions collectively represent about 58% of Ameren’s total employees. They represent 63% of the employees at UE, 82% at CIPS, 70% at Genco, 38% at CILCORP, 38% at CILCO, and 90% at IP. All collective bargaining agreements that expired in 2008 have been renegotiated and ratified. Most of the collective

bargaining agreements have four- or five-year terms, and expire in 2011 and 2012. The collective bargaining agreement between UE and IUOE Local 148, covering approximately 1,100 employees, expires on June 30, 2009.

For additional information about the development of our businesses, our business operations, and factors affecting our operations and financial position, see Management’s Discussion and Analysis of Financial Condition and Results of Operations under Part II, Item 7, of this report and Note 1 – Summary of Significant Accounting Policies to our financial statements under Part II, Item 8, of this report.

BUSINESS SEGMENTS

Ameren has three reportable segments: Missouri Regulated, Illinois Regulated, and Non-rate-regulated Generation. CILCORP and CILCO have two reportable segments: Illinois Regulated and Non-rate-regulated Generation. See Note 17 – Segment Information to our financial statements under Part II, Item 8, of this report for additional information on reporting segments.

RATES AND REGULATION

Rates

Rates that UE, CIPS, CILCO and IP are allowed to charge for their utility services are an important influence upon their and Ameren’s consolidated results of operations, financial position, and liquidity. The utility rates charged to UE, CIPS, CILCO and IP customers are determined by governmental entities. Decisions by these entities are influenced by many factors, including the cost of providing service, the quality of service, regulatory staff knowledge and experience, economic conditions, public policy, and social and political views. Decisions made by these governmental entities regarding rates, as well as the regulatory lag involved in filing and getting new rates approved, could have a material impact on the results of operations, financial position, or liquidity of UE, CIPS, CILCORP, CILCO, IP and Ameren.

The ICC regulates rates and other matters for CIPS, CILCO and IP. The MoPSC regulates rates and other matters for UE. The FERC regulates UE, CIPS, Genco, CILCO, and IP as to their ability to charge market-based rates for the sale and transmission of energy in interstate commerce and various other matters discussed below under General Regulatory Matters.

About 35% of Ameren’s electric and 14% of its gas operating revenues were subject to regulation by the MoPSC in the year ended December 31, 2008. About 41% of Ameren’s electric and 86% of its gas operating revenues were subject to regulation by the ICC in the year ended December 31, 2008. Wholesale revenues for UE, Genco and AERG are subject to FERC regulation, but not subject to direct MoPSC or ICC regulation.

 

Missouri Regulated

Electric

About 81% of UE’s electric operating revenues were subject to regulation by the MoPSC in the year ended December 31, 2008.

Following the expiration of a multiyear electric rate change moratorium, UE filed a request with the MoPSC in July 2006 for approval of an increase in its annual revenues for electric service. In May 2007, the MoPSC issued an order, that, as clarified, granted UE a $43 million increase in base rates for electric service, effective June 4, 2007.

On January 27, 2009, the MoPSC issued an order responding to UE’s April 2008 rate increase request, approving an increase for UE in annual revenues for electric service of approximately $162 million. The MoPSC also approved UE’s implementation of a FAC and a vegetation management and infrastructure inspection cost tracking mechanism. Rate changes consistent with the MoPSC order, as well as the FAC and the vegetation management and infrastructure inspection cost tracking mechanism, were effective as of March 1, 2009. These cost recovery and tracking mechanisms help to mitigate the negative effect of regulatory lag.

The MoPSC initiated a proceeding in December 2008 to develop revised rules for an environmental cost recovery mechanism, which has been authorized under Missouri law. Rules for the environmental cost recovery mechanism are expected to be approved by the MoPSC during the second quarter of 2009 and will be effective once published in the Missouri Register. UE will not be able to implement an environmental cost recovery mechanism until authorized by the MoPSC as part of a rate case proceeding. UE has not requested approval of an environmental cost recovery mechanism.

Gas

All of UE’s gas operating revenues were subject to regulation by the MoPSC in the year ended December 31, 2008.

If certain criteria are met, UE’s gas rates may be adjusted without a traditional rate proceeding. PGA clauses permit prudently incurred natural gas costs to be passed directly to the consumer. The ISRS also permits prudently incurred gas infrastructure replacement costs to be passed directly to the consumer.

As part of a 2007 stipulation and agreement approved by the MoPSC authorizing an increase in annual natural gas delivery revenues of $6 million effective April 1, 2007, UE agreed not to file a natural gas delivery rate case before March 15, 2010. This agreement did not prevent UE from filing to recover gas infrastructure replacement costs through an ISRS during this three-year rate moratorium. During 2008, the MoPSC approved two UE requests to establish an ISRS to recover annual revenues of $2 million in the aggregate, effective in March and November 2008.

Illinois Regulated

The following table presents the approximate percentage of electric and gas operating revenues subject to regulation by the ICC for each of the Illinois Regulated companies for the year ended December 31, 2008:

 

     Electric     Gas  

CIPS

   100 %   100 %

CILCORP/CILCO(a)

   56     100  

IP

   100     100  

 

(a) AERG’s revenues are not subject to ICC regulation.

If certain criteria are met, CIPS’, CILCO’s and IP’s gas rates may be adjusted without a traditional rate proceeding. PGA clauses permit prudently incurred natural gas costs to be passed directly to the consumer.

Environmental adjustment rate riders authorized by the ICC permit the recovery of prudently incurred MGP remediation and litigation costs from CIPS’, CILCO’s and IP’s Illinois electric and natural gas utility customers. In addition, IP has a tariff rider to recover the costs of asbestos-related litigation claims, subject to the following terms. Beginning in 2007, 90% of cash expenditures in excess of the amount included in base electric rates is recoverable by IP from a trust fund established by IP. At December 31, 2008, the trust fund balance was $23 million, including accumulated interest. If cash expenditures are less than the amount in base rates, IP will contribute 90% of the difference to the fund. Once the trust fund is depleted, 90% of allowed cash expenditures in excess of base rates will be recoverable through charges assessed to customers under the tariff rider.

A multiyear electric rate moratorium expired and new electric rates for CIPS, CILCO and IP went into effect on January 2, 2007. The new rates reflected delivery service tariffs approved by the ICC in November 2006 and a cost recovery mechanism for power purchased on behalf of the Ameren Illinois Utilities’ customers. In 2007, an agreement was reached among key stakeholders in Illinois to address the increase in electric rates and the future power procurement process. The Illinois electric settlement agreement provides $1 billion of funding from 2007 to 2010 for rate relief for certain electric customers in Illinois, including $488 million to customers of the Ameren Illinois Utilities. Ameren’s contributions over the four-year period under the Illinois electric settlement agreement aggregate $150 million.

 

In September 2008, responding to CIPS’, CILCO’s and IP’s November 2007 electric and natural gas rate adjustment requests, the ICC issued a consolidated order approving a net increase in annual revenues for electric service of $123 million in the aggregate (CIPS – $22 million increase, CILCO – $3 million decrease, and IP – $104 million increase) and a net increase in annual revenues for natural gas delivery service of $38 million in the aggregate (CIPS – $7 million increase, CILCO – $9 million decrease, and IP – $40 million increase). Rate changes implementing these adjustments were effective on October 1, 2008. The ICC also approved an increase in the percentage of costs to be recovered through fixed monthly charges for natural gas customers, as well as an increase in the Supply Cost Adjustment factors for the customers who take their power supply from the Ameren Illinois Utilities. These two rate structure changes help to mitigate the negative effect of regulatory lag.

For further information on Illinois rate matters, including the pending court appeal of the September 2008 consolidated electric and gas rate order, see Results of Operations and Outlook in Management’s Discussion and Analysis of Financial Condition and Results of Operations under Part II, Item 7, Quantitative and Qualitative Disclosures About Market Risk under Part II, Item 7A, and Note 2 – Rate and Regulatory Matters, and Note 15 – Commitments and Contingencies to our financial statements under Part II, Item 8, of this report.

Non-rate-regulated Generation

Non-rate-regulated Generation revenues are determined by market conditions. We expect the Non-rate-regulated Generation fleet of assets to have 6,480 megawatts of capacity available for the 2009 peak demand. As discussed below, Genco, AERG, and EEI sell all of their power and capacity to Marketing Company via power supply agreements. Marketing Company attempts to optimize the value of those generation assets and mitigate risks utilizing a variety of hedging techniques including wholesale sales of capacity and energy, retail sales in the non-rate-regulated Illinois market, spot market sales primarily in MISO and PJM, and financial transactions. Marketing Company enters into long-term and short-term contracts. Marketing Company’s counterparties include cooperatives, municipalities, commercial and industrial customers, power marketers, MISO, and investor-owned utilities like the Ameren Illinois Utilities. See Note 14 – Related Party Transactions to our financial statements under Part II, Item 8, of this report for additional information, including Marketing Company sales to the Ameren Illinois Utilities.

General Regulatory Matters

UE, CIPS, CILCO and IP must receive FERC approval to issue short-term debt securities and to conduct certain acquisitions, mergers and consolidations involving electric utility holding companies having a value in excess of $10 million. In addition, these Ameren utilities must receive

Table of Contents

authorization from the applicable state public utility regulatory agency to issue stock and long-term debt securities (with maturities of more than 12 months) and to conduct mergers, affiliate transactions, and various other activities. Genco, AERG and EEI are subject to FERC’s jurisdiction when they issue any securities.

Under PUHCA 2005, FERC and any state public utility regulatory agencies may access books and records of Ameren and its subsidiaries that are determined to be relevant to costs incurred by Ameren’s rate-regulated subsidiaries with respect to jurisdictional rates. PUHCA 2005 also permits Ameren, the ICC, or the MoPSC to request that FERC review cost allocations by Ameren Services to other Ameren companies.

Operation of UE’s Callaway nuclear plant is subject to regulation by the NRC. Its facility operating license expires on June 11, 2024. UE intends to submit a license extension application with the NRC to extend its Callaway nuclear plant’s operating license to 2044. UE’s Osage hydroelectric plant and UE’s Taum Sauk pumped-storage hydroelectric plant, as licensed projects under the Federal Power Act, are subject to FERC regulations affecting, among other things, the general operation and maintenance of the projects. The license for UE’s Osage hydroelectric plant expires on March 30, 2047, and the license for UE’s Taum Sauk plant expires on June 30, 2010. In June 2008, UE filed an application with FERC to relicense its Taum Sauk plant for another 40 years. The Taum Sauk plant is currently out of service. It is being rebuilt due to a major breach of the upper reservoir in December 2005. UE’s Keokuk plant and its dam, in the Mississippi River between Hamilton, Illinois, and Keokuk, Iowa, are operated under authority granted by an Act of Congress in 1905.

For additional information on regulatory matters, see Note 2 – Rate and Regulatory Matters and Note 15 – Commitments and Contingencies to our financial statements under Part II, Item 8, of this report, which include a discussion about the December 2005 breach of the upper reservoir at UE’s Taum Sauk pumped-storage hydroelectric plant.

Environmental Matters

Certain of our operations are subject to federal, state, and local environmental statutes or regulations relating to the safety and health of personnel, the public, and the environment. These matters include identification, generation, storage, handling, transportation, disposal, recordkeeping, labeling, reporting, and emergency response in connection with hazardous and toxic materials, safety and health standards, and environmental protection requirements, including standards and limitations relating to the discharge of air and water pollutants. Failure to comply with those statutes or regulations could have material adverse effects on us. We could be subject to criminal or civil penalties by regulatory agencies. We could be ordered to make payment to private parties by the courts. Except as indicated in this report, we believe that we

are in material compliance with existing statutes and regulations.

For additional discussion of environmental matters, including NOx, SO2, and mercury emission reduction requirements and the December 2005 breach of the upper reservoir at UE’s Taum Sauk pumped-storage hydroelectric plant, see Liquidity and Capital Resources in Management’s Discussion and Analysis of Financial Condition and Results of Operations under Part II, Item 7, and Note 15 – Commitments and Contingencies to our financial statements under Part II, Item 8, of this report.

SUPPLY FOR ELECTRIC POWER

Ameren operates an integrated transmission system that comprises the transmission assets of UE, CIPS, CILCO, IP and AITC. AITC placed its first transmission assets, jointly owned with IP, in service during the fourth quarter of 2008. Any transmission assets of AITC would be eligible for rate recovery upon making the necessary filings with and acceptance by FERC. Ameren also operates two balancing authority areas, AMMO (which includes UE) and AMIL (which includes CIPS, CILCO, IP, AITC, Genco and AERG). During 2008, the peak demand in AMMO was 8,644 MW and in AMIL was 8,794 MW. The Ameren transmission system directly connects with 17 other balancing authority areas for the exchange of electric energy.

UE, CIPS, CILCO and IP are transmission-owning members of MISO, and they have transferred functional control of their systems to MISO. Transmission service on the UE, CIPS, CILCO and IP transmission systems is provided pursuant to the terms of the MISO OATT on file with FERC. EEI operates its own balancing authority area and its own transmission facilities in southern Illinois. The EEI transmission system is directly connected to MISO and TVA. EEI’s generating units are dispatched separately from those of UE, Genco and AERG.

The Ameren Companies and EEI are members of SERC. SERC is responsible for the bulk electric power supply system in much of the southeastern United States, including all or portions of Missouri, Illinois, Arkansas, Kentucky, Tennessee, North Carolina, South Carolina, Georgia, Mississippi, Alabama, Louisiana, Virginia, Florida, Oklahoma, Iowa, and Texas. The Ameren membership covers UE, CIPS, CILCO and IP.

See Note 2 – Rate and Regulatory Matters to our financial statements under Part II, Item 8, of this report for further information.

Missouri Regulated

UE’s electric supply is obtained primarily from its own generation. Factors that could cause UE to purchase power include, among other things, absence of sufficient owned generation, plant outages, the failure of suppliers to meet their power supply obligations, extreme weather conditions, and the availability of power at a cost lower than the cost of generating it.

Table of Contents

In March 2006, UE completed the purchase of three CT facilities, totaling 1,490 megawatts of capacity, at a price of $292 million. These purchases were designed to help meet UE’s increased generating capacity needs and to provide UE with additional flexibility in determining when to add future baseload generating capacity. UE expects these CT facilities to satisfy demand growth until 2018 or 2020. However, due to the significant time required to plan, acquire permits for, and build a baseload power plant, UE is actively studying future plant alternatives, including those that would use coal or nuclear fuel. In 2008, UE filed an integrated resource plan with the MoPSC. The plan included proposals to pursue energy efficiency programs, expand the role of renewable energy sources in UE’s overall generation mix, increase operational efficiency at existing power plants, and possibly retire some generating units that are older and less efficient.

In July 2008, UE filed a COLA with the NRC for a potential new nuclear unit at UE’s existing Callaway County, Missouri, nuclear plant site. In addition, in 2008, UE filed an application with the DOE for loan guarantees associated with the potential construction of a new nuclear unit. UE has also signed contracts for certain long lead-time nuclear plant related equipment. The filing of the COLA and the DOE loan guarantee application and entering into these contracts does not mean a decision has been made to build another nuclear unit. These are only the first steps in the regulatory licensing and procurement process and are necessary actions to preserve the option to develop a new nuclear unit.

See also Outlook in Management’s Discussion and Analysis of Financial Condition and Results of Operations under Part II, Item 7 and Note 2 – Rate and Regulatory Matters and Note 15 – Commitments and Contingencies to our financial statements under Part II, Item 8, of this report.

Illinois Regulated

As of January 1, 2007, CIPS, CILCO and IP were required to obtain all electric supply requirements for customers who did not purchase electric supply from third-party suppliers. The power procurement costs incurred by CIPS, CILCO and IP are passed directly to their customers through a cost recovery mechanism.

In September 2006, a reverse power procurement auction was held, as a result of which CIPS, CILCO and IP entered into power supply contracts with the winning bidders, including Marketing Company. Under these contracts, the electric suppliers are responsible for providing to CIPS, CILCO and IP energy, capacity, certain transmission, volumetric risk management, and other services necessary for the Ameren Illinois Utilities to serve the electric load needs of fixed price residential and small commercial customers (with less than one MW of demand) at an all-inclusive fixed price. These contracts commenced on January 1, 2007, with one-third of the supply contracts expiring in each of May 2008, 2009 and 2010.

 

As part of the Illinois electric settlement agreement reached in 2007, the reverse power procurement auction process in Illinois was discontinued. It was replaced with a new power procurement process led by the IPA beginning in 2009. Under the new plan, the IPA will procure separate wholesale products (capacity, energy swaps and renewable energy credits) on behalf of the Ameren Illinois Utilities for the period of June 1, 2009, through May 30, 2014. The products will be procured through a RFP process, which is expected to begin during the first half of 2009. In 2008, utilities contracted for necessary power and energy requirements not already supplied through the September 2006 auction contracts, primarily through a RFP process that was subject to ICC review and approval.

A portion of the electric power supply required for the Ameren Illinois Utilities to satisfy their distribution customers’ requirements is purchased from Marketing Company on behalf of Genco, AERG and EEI. Also as part of the Illinois electric settlement agreement, the Ameren Illinois Utilities entered into financial contracts with Marketing Company (for the benefit of Genco and AERG), to lock in energy prices for 400 to 1,000 megawatts annually of their round-the-clock power requirements during the period June 1, 2008, to December 31, 2012, at relevant market prices at that time. These financial contracts do not include capacity, are not load-following products, and do not involve the physical delivery of energy.

See Note 2 – Rate and Regulatory Matters and Note 14 – Related Party Transactions to our financial statements under Part II, Item 8, of this report for additional information on power procurement in Illinois.

Non-rate-regulated Generation

In December 2006, Genco and Marketing Company, and AERG and Marketing Company, entered into power supply agreements whereby Genco and AERG sell and Marketing Company purchases all the capacity available from Genco’s and AERG’s generation fleets and the associated energy commencing on January 1, 2007. These power supply agreements continue through December 31, 2022, and from year to year thereafter unless either party elects to terminate the agreement by providing the other party with no less than six months advance written notice. In December 2005, EEI and Marketing Company entered into a power supply agreement whereby EEI sells all of its capacity and energy to Marketing Company commencing January 1, 2006. This agreement expires on December 31, 2015. All of Genco’s, AERG’s and EEI’s generating capacity competes for the sale of energy and capacity in the competitive energy markets through Marketing Company. See Note 14 – Related Party Transactions to our financial statements under Part II, Item 8, of this report for additional information.

Factors that could cause Marketing Company to purchase power for the Non-rate-regulated Generation business segment include, among other things, absence of sufficient owned generation, plant outages, the failure of suppliers to meet their power supply obligations, and extreme weather conditions.

UE, Genco, AERG and EEI have agreements in place to purchase a portion of their coal needs and to transport it to electric generating facilities through 2012. UE, Genco, AERG and EEI expect to enter into additional contracts to purchase coal. Coal supply agreements typically have an initial term of five years, with about 20% of the contracts expiring annually. Ameren burned 40.3 million (UE – 22.0 million, Genco – 9.6 million, AERG – 3.7 million, EEI – 5.0 million) tons of coal in 2008. See Part II, Item 7A – Quantitative and Qualitative Disclosures About Market Risk of this report for additional information about coal supply contracts.

About 96% of Ameren’s coal (UE – 97%, Genco – 98%, AERG – 77%, EEI – 100%) is purchased from the Powder River Basin in Wyoming. The remaining coal is typically purchased from the Illinois Basin. UE, Genco, AERG and EEI have a policy to maintain coal inventory consistent with their projected usage. Inventory may be adjusted because of uncertainties of supply due to potential work stoppages, delays in coal deliveries,

equipment breakdowns, and other factors. In the past, deliveries from the Powder River Basin have been restricted because of rail maintenance, weather and derailments. As of December 31, 2008, coal inventories for UE, Genco, AERG and EEI were adequate and at targeted levels. Disruptions in coal deliveries could cause UE, Genco, AERG and EEI to pursue a strategy that could include reducing sales of power during low-margin periods, buying higher-cost fuels to generate required electricity, and purchasing power from other sources.

Nuclear

Developing nuclear generating fuel generally involves the mining and milling of uranium ore to produce uranium concentrates, the conversion of uranium concentrates to uranium hexafluoride gas, enrichment of that gas, and then the fabrication of the enriched uranium hexafluoride gas into usable fuel assemblies. UE has entered into uranium, uranium conversion, enrichment, and fabrication contracts to procure the fuel supply for its Callaway nuclear plant.

Table of Contents

Fuel assemblies for the 2010 spring refueling at UE’s Callaway nuclear plant will begin manufacture during the fourth quarter of 2009. Enriched uranium for such assemblies is in inventory. UE also has agreements or inventories to price-hedge approximately 95% of Callaway’s 2010 and 55% of Callaway’s 2011 refueling requirements. UE has uranium (concentrate and hexafluoride) inventories and supply contracts sufficient to meet all of its uranium and conversion requirements through at least 2014. UE has enriched uranium inventories and enrichment supply contracts sufficient to satisfy enrichment requirements through 2012. Fuel fabrication services are under contract through 2010. UE expects to enter into additional contracts to purchase nuclear fuel. As a member of Fuelco, UE can join with other member companies to increase its purchasing power and opportunities for volume discounts. The Callaway nuclear plant normally requires refueling at 18-month intervals. The last refueling was completed in November 2008. There is no refueling scheduled in 2009 or 2012. The nuclear fuel markets are competitive, and prices can be volatile; however, we do not anticipate any significant problems in meeting our future supply requirements.

Natural Gas Supply

To maintain gas deliveries to gas-fired generating units throughout the year, especially during the summer peak demand, Ameren’s portfolio of natural gas supply resources includes firm transportation capacity and firm no-notice storage capacity leased from interstate pipelines. UE, Genco and EEI primarily use the interstate pipeline systems of Panhandle Eastern Pipe Line Company, Trunkline Gas Company, Natural Gas Pipeline Company of America, and Mississippi River Transmission Corporation to transport natural gas to generating units. In addition to physical transactions, Ameren uses financial instruments, including some in the NYMEX futures market and some in the OTC financial markets, to hedge the price paid for natural gas.

UE, Genco and EEI’s natural gas procurement strategy is designed to ensure reliable and immediate delivery of natural gas to their generating units. UE, Genco and EEI do this in two ways. They optimize transportation and storage options and minimize cost and price risk through various supply and price hedging agreements that allow them to maintain access to multiple gas pools, supply basins, and storage. As of December 31, 2008, UE had price-hedged about 22% and Genco had price-hedged about 30% of their required gas supply for generation in 2009. As of December 31, 2008, EEI did not have any of its required gas supply for generation hedged for price risk.

NATURAL GAS SUPPLY FOR DISTRIBUTION

UE, CIPS, CILCO and IP are responsible for the purchase and delivery of natural gas to their gas utility customers. UE, CIPS, CILCO and IP develop and manage a portfolio of gas supply resources. These include firm gas supply under term agreements with producers, interstate and intrastate firm transportation capacity, firm storage capacity leased from interstate pipelines, and on-system

storage facilities to maintain gas deliveries to customers throughout the year and especially during peak demand. UE, CIPS, CILCO and IP primarily use the Panhandle Eastern Pipe Line Company, the Trunkline Gas Company, the Natural Gas Pipeline Company of America, the Mississippi River Transmission Corporation, and the Texas Eastern Transmission Corporation interstate pipeline systems to transport natural gas to their systems. In addition to physical transactions, financial instruments, including those entered into in the NYMEX futures market and in the OTC financial markets, are used to hedge the price paid for natural gas. See Part II, Item 7A – Quantitative and Qualitative Disclosures About Market Risk of this report for additional information about natural gas supply contracts. Prudently incurred natural gas purchase costs are passed on to customers of UE, CIPS, CILCO and IP in Illinois and Missouri under PGA clauses, subject to prudency review by the ICC and the MoPSC.

INDUSTRY ISSUES

We are facing issues common to the electric and gas utility industry and the non-rate-regulated electric generation industry. These issues include:

 

Ÿ  

political and regulatory resistance to higher rates, especially in a recessionary economic environment;

Ÿ  

the potential for changes in laws, regulation, and policies at the state and federal level, including those resulting from election cycles;

Ÿ  

access to and uncertainty in the capital and credit markets;

Ÿ  

the potential for more intense competition in generation and supply;

Ÿ  

pressure on customer growth and usage in light of current economic conditions;

Ÿ  

the potential for reregulation in some states, including Illinois, which could cause electric distribution companies to build or acquire generation facilities and to purchase less power from electric generating companies like Genco, AERG and EEI;

Ÿ  

changes in the structure of the industry as a result of changes in federal and state laws, including the

 

formation of non-rate-regulated generating entities and RTOs;

Ÿ  

increases or decreases in power prices due to the balance of supply and demand;


 

11


Table of Contents
Ÿ  

the availability of fuel and increases or decreases in fuel prices;

Ÿ  

the availability of labor and material and rising costs;

Ÿ  

regulatory lag;

Ÿ  

negative free cash flows due to rising investments and the regulatory framework;

Ÿ

Table of Contents

The electric and gas rates that UE, CIPS, CILCO and IP are allowed to charge are determined through regulatory proceedings and are subject to legislative actions, which are largely outside of their control. Any such events that prevent UE, CIPS, CILCO or IP from recovering their respective costs or from earning appropriate returns on their investments could have a material adverse effect on future results of operations, financial position, or liquidity.

The rates that UE, CIPS, CILCO and IP are allowed to charge for their services are an important item influencing the results of operations, financial position, and liquidity of these companies and Ameren. The electric and gas utility industry is highly regulated. The regulation of the rates that utility customers are charged is determined, in large part, by governmental entities, including the MoPSC, the ICC, and FERC. Decisions by these entities are influenced by many factors, including the cost of providing service, the quality of service, regulatory staff knowledge and experience, economic conditions, public policy, and social and political views and are largely outside of our control. Decisions made by these entities could have a material adverse effect on results of operations, financial position, or liquidity.

UE, CIPS, CILCO and IP electric and gas utility rates are typically established in regulatory proceedings that take up to 11 months to complete. Rates established in those proceedings are primarily based on historical costs, and they include an allowed return on investments by the regulator.

Our company, and the industry as a whole, is going through a period of rising costs and investments. The fact that rates at UE, CIPS, CILCO and IP are primarily based on historical costs means that these companies may not be able to earn the allowed return established by their regulators (often referred to as regulatory lag). As a result, UE, CIPS, CILCO and IP expect to file more frequent rate cases. A period of increasing rates to our customers, especially during weak economic times, could result in additional regulatory and legislative actions, as well as competitive and political pressures, that could have a material adverse effect on our results of operations, financial position, or liquidity.

We are subject to various environmental laws and regulations that require significant capital expenditures, can increase our operating costs, and may adversely influence or limit our results of operations, financial position or liquidity or expose us to environmental fines and liabilities.

We are subject to various environmental laws and regulations enforced by federal, state and local authorities. From the beginning phases of siting and development to the ongoing operation of existing or new electric generating, transmission and distribution facilities, natural gas storage plants, and natural gas transmission and distribution facilities, our activities involve compliance with diverse laws and regulations. These laws and regulations address noise,

emissions, impacts to air and water, protected and cultural resources (such as wetlands, endangered species, and archeological and historical resources), and chemical and waste handling. Complex and lengthy processes are required to obtain approvals, permits or licenses for new, existing or modified facilities. Additionally, the use and handling of various chemicals or hazardous materials (including wastes) requires release prevention plans and emergency response procedures.

Compliance with environmental laws and regulations can require significant capital expenditures and operating costs. Actions required to ensure that our facilities are in compliance with environmental laws and regulations could be prohibitively expensive. As a result, we could be required to close or alter the operation of our facilities, which could have an adverse effect on our results of operations, financial position, and liquidity.

Failure to comply with environmental laws and regulations may also result in the imposition of fines, penalties, and injunctive measures affecting operating assets. We are also subject to liability under environmental laws for remediating environmental contamination of property now or formerly owned by us or by our predecessors, as well as property contaminated by hazardous substances that we generated. Such sites include MGP sites and third-party sites, such as landfills. Additionally, private individuals may seek to enforce environmental laws and regulations against us and could allege injury from exposure to hazardous materials.

About 85% of Ameren’s (UE – 77%, Genco – 99%, CILCO (through AERG) – 99%, EEI – 100%) generating capacity is coal-fired. The remaining electric generation comes from nuclear, gas-fired, hydroelectric, and oil-fired power plants. Federal and state laws require significant reductions in SO2, NOx and mercury emissions from coal-fired plants.

Ameren’s estimated capital costs through 2018, based on current technology, to comply with the federal Clean Air Interstate Rule and related state implementation plans and the MPS as well as federal ambient air quality standards including ozone and fine particulates, and the federal Clean Air Visibility Rule range from $4.5 billion to $5.5 billion (UE – $2.2 billion to $2.6 billion; Genco – $1.2 billion to $1.4 billion, CILCO (through AERG) – $480 million to $590 million, EEI – $665 million to $830 million). In addition, the Ameren Companies could incur additional capital costs with respect to a MACT standard for mercury emissions. The EPA is expected to move forward with a MACT standard for mercury emissions as the U.S. Supreme Court denied in February 2009 a petition to review a U.S. Court of Appeals decision that vacated the federal Clean Air Mercury Rule. Further, with respect to the EPA’s enforcement initiative to determine whether modifications at a number of coal-fired power plants owned by electric utilities in the United States are subject to the New Source Review requirements or New Source Performance Standards under the Clean Air Act, Ameren, UE, Genco, AERG and EEI could incur increased capital expenditures for

Table of Contents

the installation of control technology, increased operations and maintenance expenses, as well as fines or penalties.

New environmental regulations, voluntary compliance guidelines, enforcement initiatives, or legislation could result in a significant increase in capital expenditures and operating costs, decreased revenues, increased financing requirements, penalties, or closure of power plants for UE, Genco, AERG and EEI. Although costs incurred by UE would be eligible for recovery in rates over time, subject to MoPSC approval in a rate proceeding, there is no similar mechanism for recovery of costs for Genco, AERG or EEI. We are unable to predict the ultimate impact of these matters on our results of operations, financial position or liquidity.

Future limits on greenhouse gas emissions would likely require UE, Genco, CILCO (through AERG) and EEI to incur significant increases in capital expenditures and operating costs, which, if excessive, could result in the closures of coal-fired generating plants or otherwise materially adversely affect our results of operations, financial position or liquidity.

Future initiatives regarding greenhouse gas emissions and global warming are subject to active consideration in the U.S. Congress. In October 2008, the U.S. House of Representatives, Energy and Commerce Committee, Subcommittee on Energy and Air Quality issued a “discussion draft” of climate legislation, which proposed establishing an economy-wide cap-and-trade program. The overarching goal of such legislation is to reduce greenhouse gas emissions to 6% below 2005 levels by 2020 and to 80% below 2005 levels by 2050. In addition, new leadership in the Energy and Commerce Committee is considering aggressive climate legislation. Finally, President Obama supports an economy-wide cap-and-trade greenhouse gas reduction program that would reduce emissions to 1990 levels by 2020 and 80% below 1990 levels by 2050. President Obama has also indicated support for auctioning 100% of the emission allowances to be distributed under the legislation. Although we cannot predict the date of enactment or the requirements of any global warming legislation or regulations, we believe it is likely that some form of federal greenhouse gas legislation or regulations will become law during President Obama’s administration.

As a result of our diverse fuel portfolio, our contribution to greenhouse gases varies among our generating facilities, but coal-fired power plants are significant sources of CO2, a principal greenhouse gas. Ameren’s current analysis shows that under some policy scenarios being considered in the U.S. Congress, household costs and rates for electricity could rise significantly. The burden could fall particularly hard on electricity consumers and the Midwest economy because of our region’s reliance on electricity generated by coal-fired power plants. Natural gas emits about half the amount of CO2 that coal emits when burned to produce electricity. As a result, economy-wide shifts favoring natural gas as a fuel source for electric generation could affect the cost of heating for our utility customers and many industrial

processes. Ameren believes that under some policy scenarios being considered by Congress, wholesale natural gas costs could rise significantly as well. Higher costs for energy could contribute to reduced demand for both electricity and natural gas.

Future initiatives regarding greenhouse gas emissions and global warming may also be subject to the activities pursuant to the Midwest Greenhouse Gas Reduction Accord, an agreement signed by the governors of Illinois, Iowa, Kansas, Michigan, Wisconsin and Minnesota to develop a strategy to achieve energy security and reduce greenhouse gas emissions through a cap-and-trade mechanism. It is expected that the advisory group to the Midwest governors will provide recommendations on the design of a greenhouse gas reduction program by the third quarter of 2009. However, it is uncertain whether legislation to implement the recommendations will be implemented or passed by any of the states, including Illinois.

With regard to greenhouse gas regulation under existing law, in April 2007, the U.S. Supreme Court issued a decision that the EPA has the authority to regulate CO2 and other greenhouse gases from automobiles as “air pollutants” under the Clean Air Act. This decision was a result of a Bush Administration ruling denying a waiver request by the state of California to implement such regulations. The Supreme Court sent the case back to the EPA, which must conduct a rulemaking process to determine whether greenhouse gas emissions contribute to climate change “which may reasonably be anticipated to endanger public health or welfare.” In July 2008, the EPA issued an advance notice of public rulemaking (ANPR) in response to the U.S. Supreme Court’s directive. The ANPR solicited public comments on the benefits and ramifications of regulating greenhouse gases under the Clean Air Act, and that rulemaking has not been completed. On February 12, 2009, the EPA announced its intent to reconsider the decision under the Bush Administration denying the waiver to the state of California for regulating CO2 emissions from automobiles. On February 17, 2009, the EPA also granted a petition for reconsideration filed by the Sierra Club to reexamine a December 2008 Bush Administration ruling that CO2 should not be regulated under the Clean Air Act when issuing construction permits for power plants. These EPA actions will factor into the rulemaking process on the ANPR and could ultimately lead to regulation of CO2 from power plants.

Future federal and state legislation or regulations that mandate limits on the emission of greenhouse gases would result in significant increases in capital expenditures and operating costs, which, in turn, could lead to increased liquidity needs and higher financing costs. Excessive costs to comply with future legislation or regulations might force UE, Genco, CILCO (through AERG) and EEI and other similarly situated electric power generators to close some coal-fired facilities and could lead to possible impairment of assets. As a result, mandatory limits could have a material adverse impact on Ameren’s, UE’s, Genco’s, CILCO’s (through AERG) and EEI’s results of operations, financial position, or liquidity.

The construction of, and capital improvements to, UE’s, CIPS’, CILCO’s and IP’s electric and gas utility infrastructure as well as to Genco’s, CILCO’s (through AERG) and EEI’s non-rate-regulated generation facilities involve substantial risks. These risks include escalating costs, performance of the projects when completed and the ability to complete projects as scheduled, which could result in the closure of facilities and higher costs.

Over the next five years, the Ameren Companies will incur significant capital expenditures for compliance with environmental regulations and to make significant investments in their electric and gas utility infrastructure and their non-rate-regulated generation facilities. The Ameren Companies estimate that they will incur up to $10.4 billion (UE – up to $5.3 billion; CIPS – up to $565 million; Genco – up to $1.8 billion; CILCO (Illinois Regulated) – up to $415 million; CILCO (AERG) – up to $640 million; IP – up to $1.2 billion; EEI – up to $385 million; Other – up to $160 million) of capital expenditures during the period 2009 through 2013. These expenses include construction expenditures, capitalized interest or allowance for funds used during construction, and compliance with EPA and state regulations regarding SO2 and NOx emissions and mercury emissions from coal-fired power plants. Costs for these types of projects have escalated in recent years and are expected to either stay at current levels or further escalate.

Investments in Ameren’s regulated operations are expected to be recoverable from ratepayers, but are subject to prudency reviews. The recoverability of amounts expended in non-rate-regulated generation operations will depend on whether market prices for power adjust to reflect increased costs for generators.

The ability of the Ameren Companies to complete facilities under construction successfully, and to complete future projects within established estimates, is contingent upon many variables and subject to substantial risks. These variables include, but are not limited to, project management expertise and escalating costs for materials, labor, and environmental compliance. Delays in obtaining permits, shortages in materials and qualified labor, suppliers and contractors not performing as required under their contracts, changes in the scope and timing of projects, the inability to raise capital on favorable terms, or other events beyond our control may occur that may materially affect the schedule, cost and performance of these projects. With respect to capital spent for pollution control equipment, there is a risk that electric generating plants will not be permitted to continue to operate if pollution control equipment is not installed by prescribed deadlines or does not perform as expected. Should any such construction efforts be unsuccessful, the Ameren Companies could be subject to additional costs and the loss of their investment in the project or facility. The Ameren Companies may also be required to purchase additional electricity or natural gas for their customers until the projects are completed. All of these risks may have a material adverse effect on the Ameren Companies’ results of operations, financial position, or liquidity.

 

Our counterparties may not meet their obligations to us.

We are exposed to the risk that counterparties to various arrangements who owe us money, energy, coal, or other commodities or services will not be able to perform their obligations or, with respect to our credit facilities, will fail to honor their commitments. Should the counterparties to commodity arrangements fail to perform, we might be forced to replace or to sell the underlying commitment at then-current market prices. Should the lenders under our current credit facilities fail to perform, the level of borrowing capacity under those arrangements would decrease unless we were able to find replacement lenders to assume the nonperforming lender’s commitment. In such an event, we might incur losses, or our results of operations, financial position, or liquidity could otherwise be adversely affected.

Certain of the Ameren Companies have obligations to other Ameren Companies or other Ameren subsidiaries because of transactions involving energy, coal, other commodities, services, and because of hedging transactions. If one Ameren entity failed to perform under any of these arrangements, other Ameren entities might incur losses. Their results of operations, financial position, or liquidity could be adversely affected, resulting in the nondefaulting Ameren entity being unable to meet its obligations to unrelated third-parties. Our hedging activities are generally undertaken with a view to the Ameren-wide exposures. Some Ameren Companies may therefore be more or less hedged than if they were to engage in such hedging alone.

Increasing costs associated with our defined benefit retirement plans, health care plans, and other employee- related benefits may adversely affect our results of operations, financial position, or liquidity.

We offer defined benefit and postretirement plans that cover substantially all of our employees. Assumptions related to future costs, returns on investments, interest rates, and other actuarial matters have a significant impact on our earnings and funding requirements. Ameren expects to fund its pension plans at a level equal at least to the pension expense. Based on Ameren’s assumptions at December 31, 2008, and reflecting this pension funding policy, Ameren expects to make annual contributions of $90 million to $200 million in each of the next five years. We expect UE’s, CIPS’, Genco’s, CILCO’s, and IP’s portion of the future funding requirements to be 61%, 6%, 10%, 9%, and 14%, respectively. These amounts are estimates. They may change with actual investment performance, changes in interest rates, any pertinent changes in government regulations, and any voluntary contributions.

In addition to the costs of our retirement plans, the costs of providing health care benefits to our employees and retirees have increased in recent years. We believe that our employee benefit costs, including costs of health care plans for our employees and former employees, will continue to rise. The increasing costs and funding requirements associated with our defined benefit retirement plans, health care plans, and other employee benefits may adversely affect our results of operations, financial position, or liquidity.

Our electric generating, transmission and distribution facilities are subject to operational risks that could adversely affect our results of operations, liquidity, and financial position.

The Ameren Companies’ financial performance depends on the successful operation of electric generating, transmission, and distribution facilities. Operation of electric generating, transmission, and distribution facilities involves many risks, including:

 

Ÿ  

increased prices for fuel and fuel transportation;

Ÿ  

facility shutdowns due to operator error or a failure of equipment or processes;

Ÿ  

longer-than-anticipated maintenance outages;

Ÿ  

disruptions in the delivery of fuel and lack of adequate inventories;

Ÿ  

increased purchased power costs;

Ÿ  

lack of water for cooling plant operations;

Ÿ  

labor disputes;

Ÿ  

inability to comply with regulatory or permit requirements, including environmental contamination;

Ÿ  

disruptions in the delivery of electricity, including impacts on us or our customers;

Ÿ  

increased capital expenditure requirements, including those due to environmental regulation;

Ÿ  

handling and storage of fossil-fuel combustion waste products, such as coal ash;

Ÿ  

unusual or adverse weather conditions, including severe storms, drought and floods;

Ÿ  

a workplace accident that might result in injury or loss of life, extensive property damage or environmental damage;

Ÿ  

information security risk, such as a breach of our systems on which sensitive utility customer data and account information are stored;

Ÿ  

catastrophic events such as fires, explosions, or other similar occurrences; and

Ÿ  

other unanticipated operations and maintenance expenses and liabilities.

Even though agreements have been reached with the state of Missouri and the FERC, the breach of the upper reservoir of UE’s Taum Sauk pumped-storage hydroelectric facility could continue to have an adverse effect on Ameren’s and UE’s results of operations, liquidity, and financial condition.

In December 2005, there was a breach of the upper reservoir at UE’s Taum Sauk pumped-storage hydroelectric facility. This resulted in significant flooding in the local area, which damaged a state park.

UE has settled with the FERC and the state of Missouri all issues associated with the December 2005 Taum Sauk incident. Other parties have also claimed damages as a result of the incident. UE has begun rebuilding the upper reservoir at its Taum Sauk plant. The estimated cost to rebuild the upper reservoir is in the range of $480 million. UE expects the Taum Sauk plant to be out of service through early 2010.

 

If UE must purchase power because of the unavailability of the Taum Sauk facility during the rebuild of the upper reservoir, UE has committed to not seek recovery of these additional costs from ratepayers. The Taum Sauk incident is expected to reduce Ameren’s and UE’s 2009 pretax earnings by $15 million to $20 million, excluding any unreimbursed costs related to the incident or the rebuild, which are currently not expected. UE expects to realize higher-cost sources of power, reduced interchange sales, and increased expenses, net of insurance reimbursement for replacement power costs.

At this time, UE believes that substantially all damages and liabilities caused by the breach, including costs related to the settlement agreement with the state of Missouri, the cost of rebuilding the plant, and the cost of replacement power, up to $8 million annually, will be covered by insurance. Insurance will not cover lost electric margins and penalties. Under UE’s insurance policies, all claims by or against UE are subject to review by its insurance carriers. As a result of this breach, UE is engaged in litigation initiated by certain private parties and the Department of the Army, Corp of Engineers. Until all litigation has been resolved and the insurance review is completed, among other things, we are unable to determine the total impact the breach may have on Ameren’s and UE’s results of operations, financial position, or liquidity beyond those amounts already recognized.

Genco’s, AERG’s, and EEI’s electric generating facilities must compete for the sale of energy and capacity, which exposes them to price risks.

All of Genco’s, AERG’s, and EEI’s generating facilities compete for the sale of energy and capacity in the competitive energy markets.

To the extent that electricity generated by these facilities is not under a fixed-price contract to be sold, the revenues and results of operations of these non-rate-regulated subsidiaries generally depend on the prices that can be obtained for energy and capacity in Illinois and adjacent markets. Among the factors that could influence such prices (all of which are beyond our control to a significant degree) are:

 

Ÿ  

current and future delivered market prices for natural gas, fuel oil, and coal and related transportation costs;

Ÿ  

current and forward prices for the sale of electricity;

Ÿ  

the extent of additional supplies of electric energy from current competitors or new market entrants;

Ÿ  

the regulatory and market structures developed for evolving Midwest energy markets;

Ÿ  

changes enacted by the Illinois legislature, the ICC, the IPA or other government agencies with respect to power procurement procedures;

Ÿ  

the potential for reregulation of generation in some states;

Ÿ  

future pricing for, and availability of, services on transmission systems, and the effect of RTOs and export energy transmission constraints, which could limit our ability to sell energy in our markets;

UE’s ownership and operation of a nuclear generating facility creates business, financial, and waste disposal risks.

UE owns the Callaway nuclear plant, which represents about 12% of UE’s generation capacity and produced 19% of UE’s 2008 generation. Therefore, UE is subject to the risks of nuclear generation, which include the following:

 

Ÿ  

potential harmful effects on the environment and human health resulting from the operation of nuclear facilities and the storage, handling and disposal of radioactive materials;

Ÿ  

the lack of a permanent waste storage site;

Ÿ  

limitations on the amounts and types of insurance commercially available to cover losses that might arise in connection with UE or other U.S. nuclear operations;

Ÿ  

uncertainties with respect to contingencies and assessment amounts if insurance coverage is inadequate;

Ÿ  

public and governmental concerns over the adequacy of security at nuclear power plants;

Ÿ  

uncertainties with respect to the technological and financial aspects of decommissioning nuclear plants at the end of their licensed lives (UE’s facility operating license for the Callaway nuclear plant expires in 2024);

Ÿ  

limited availability of fuel supply; and

Ÿ  

costly and extended outages for scheduled or unscheduled maintenance and refueling.

The NRC has broad authority under federal law to impose licensing and safety requirements for nuclear generation facilities. In the event of noncompliance, the NRC has the authority to impose fines, shut down a unit, or both, depending upon its assessment of the severity of the situation, until compliance is achieved. Revised safety requirements promulgated by the NRC could necessitate substantial capital expenditures at nuclear plants such as UE’s. In addition, if a serious nuclear incident were to occur, it could have a material but indeterminable adverse effect on UE’s results of operations, financial position, or liquidity. A major incident at a nuclear facility anywhere in the world could cause the NRC to limit or prohibit the operation or relicensing of any domestic nuclear unit.

Our energy risk management strategies may not be effective in managing fuel and electricity procurement and pricing risks, which could result in unanticipated liabilities or increased volatility in our earnings and cash flows.

We are exposed to changes in market prices for natural gas, fuel, electricity, emission allowances, and transmission congestion. Prices for natural gas, fuel, electricity, and emission allowances may fluctuate substantially over relatively short periods of time and expose us to commodity

price risk. We use short-term and long-term purchase and sales contracts in addition to derivatives such as forward contracts, futures contracts, options, and swaps to manage these risks. We attempt to manage our risk associated with these activities through enforcement of established risk limits and risk management procedures. We cannot ensure that these strategies will be successful in managing our pricing risk or that they will not result in net liabilities because of future volatility in these markets.

Although we routinely enter into contracts to hedge our exposure to the risks of demand and changes in commodity prices, we do not hedge the entire exposure of our operations from commodity price volatility. Furthermore, our ability to hedge our exposure to commodity price volatility depends on liquid commodity markets. To the extent that commodity markets are illiquid, we may not be able to execute our risk management strategies, which could result in greater unhedged positions than we would prefer at a given time. To the extent that unhedged positions exist, fluctuating commodity prices can adversely affect our results of operations, financial position, or liquidity.

Our facilities are considered critical energy infrastructure and may therefore be targets of acts of terrorism.

Like other electric and gas utilities and other non-rate-regulated electric generators, our power generation plants, fuel storage facilities, and transmission and distribution facilities may be targets of terrorist activities that could result in disruption of our ability to produce or distribute some portion of our energy products. Any such disruption could result in a significant decrease in revenues or significant additional costs for repair, which could have a material adverse effect on our results of operations, financial position, or liquidity.

Our businesses are dependent on our ability to access the capital markets successfully. We may not have access to sufficient capital in the amounts and at the times needed.

The global capital and credit markets experienced extreme volatility and disruption in 2008, and we expect those conditions to continue throughout 2009. Several factors have driven this situation, including deteriorating global economic conditions and the weakened condition of major financial institutions. The extreme disruption in the financial markets has limited companies’, including the Ameren Companies’, ability to access the debt and equity capital markets as well as credit markets to support their operations and refinance debt, which has led to higher financing costs compared to recent years. At December 31, 2008, the Ameren Companies had in place revolving bank credit facilities aggregating $2.15 billion, the size of which would be reduced if any of the participating banks fail to honor their commitments. In total, 18 banks participated in these credit facilities.

We use short-term and long-term debt as a significant source of liquidity and funding for capital requirements not


 

19


Table of Contents

satisfied by our operating cash flow, including requirements related to future environmental compliance. As a result of rising costs and increased capital and operations and maintenance expenditures, coupled with near-term regulatory lag, we expect to need more short-term and long-term debt financing. The inability to raise debt or equity capital on favorable terms, or at all, particularly during times of uncertainty in the capital markets, could negatively affect our ability to maintain and to expand our businesses. Our current credit ratings cause us to believe that we will continue to have access to the capital markets. However, events beyond our control, such as the extreme volatility and disruption in global debt or equity capital and credit markets in 2008 and 2009, may create uncertainty that could increase our cost of capital or impair, or eliminate, our ability to access the debt, equity or credit markets, including the ability to draw on our bank credit facilities. Certain of the Ameren Companies rely, in part, on Ameren for access to capital. Circumstances that limit Ameren’s access to capital, including those relating to its other subsidiaries, could impair its ability to provide those Ameren Companies with needed capital.

The Ameren Companies have certain debt that matures, and credit facilities that expire, in 2009 and 2010. Although we are actively developing plans and strategies to refinance or otherwise repay this debt and to renew or replace these credit facilities, we are unable to predict capital market conditions, our access to the capital markets or the degree of success we will have in renewing or replacing any of the credit facilities and whether the size and terms of any new credit facilities will be comparable to the existing credit facilities.

Ameren’s and some of the Ameren Companies’ holding company structures could limit their ability to pay common stock dividends, to service their respective debt obligations and to pay dividends on their outstanding preferred stock, as applicable.

Ameren is a holding company, and therefore, its primary assets are the common stock of its subsidiaries. As

a result, Ameren’s ability to pay dividends on its common stock depends on the earnings of its subsidiaries and the ability of its subsidiaries to pay dividends or otherwise transfer funds to Ameren. Similarly, Ameren’s and some of the Ameren Companies’ ability to service their respective debt obligations and to pay dividends on their respective preferred stock are also dependent upon the earnings of operating subsidiaries and the distribution of those earnings and other payments, including payments of principal and interest under intercompany indebtedness. The payment of dividends to Ameren by its subsidiaries in turn depends on their results of operations and cash flows and other items affecting retained earnings. Ameren’s subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any dividends or make any other distributions (except for payments required pursuant to the terms of intercompany borrowing arrangements) to Ameren. Certain of the Ameren Companies’ financing agreements and articles of incorporation, in addition to certain statutory and regulatory requirements, may impose certain restrictions on the ability of such Ameren Companies to transfer funds to Ameren in the form of cash dividends, loans or advances.

Failure to retain and attract key officers and other skilled professional and technical employees could have an adverse effect on our operations.

Our businesses depend upon our ability to employ and retain key officers and other skilled professional and technical employees. A significant portion of our workforce is nearing retirement, including many employees with specialized skills such as maintaining and servicing our electric and natural gas infrastructure and operating our generating units. Our inability to retain and recruit qualified employees could adversely affect our results of operations.

A portion of UE’s Osage plant reservoir, certain facilities at UE’s Sioux plant, most of UE’s Peno Creek and Audrain CT facilities, Genco’s Columbia CT facility, AERG’s Indian Trails generating facility, Medina Valley’s generating facility, certain of Ameren’s substations, and most of our transmission and distribution lines and gas mains are situated on lands we occupy under leases, easements, franchises, licenses or permits.

Ÿ  

The United States or the state of Missouri may own or may have paramount rights to certain lands lying in the bed of the Osage River or located between the inner and outer harbor lines of the Mississippi River on which certain of UE’s generating and other properties are located.

Ÿ  

The United States, the state of Illinois, the state of Iowa, or the city of Keokuk, Iowa, may own or may have paramount rights with respect to certain lands lying in the bed of the Mississippi River on which a portion of UE’s Keokuk plant is located.

Substantially all of the properties and plant of UE, CIPS, CILCO and IP are subject to the direct first liens of the indentures securing their mortgage bonds. In July 2006 and February 2007, AERG recorded open-ended mortgages and security agreements with respect to its E.D. Edwards and Duck Creek power plants. These plants serve as collateral to secure its obligations under multiyear, senior secured credit facilities entered into on July 14, 2006, and February 9,

2007, along with other Ameren subsidiaries. See Note 4 – Short-term Borrowings and Liquidity under Part II, Item 8, of this report for details of the credit facilities.

UE has conveyed most of its Peno Creek CT facility to the city of Bowling Green, Missouri, and leased the facility back from the city through 2022. Under the terms of this capital lease, UE is responsible for all operation and maintenance responsibilities for the facility. Ownership of the facility will transfer to UE at the expiration of the lease, at which time the property and plant will become subject to the lien of any outstanding UE first mortgage bond indenture.

In March 2006, UE purchased a CT facility located in Audrain County, Missouri, from NRG Audrain Holding, LLC, and NRG Audrain Generating LLC, both affiliates of NRG Energy, Inc. (collectively, NRG). As a part of this transaction, UE was assigned the rights of NRG as lessee of the CT facility under a long-term lease with Audrain County and assumed NRG’s obligations under the lease. The lease term will expire on December 1, 2023. Under the terms of this capital lease, UE has all operation and maintenance responsibilities for the facility, and ownership of the facility will be transferred to UE at the expiration of the lease. When ownership of the Audrain County CT facility is transferred to UE by the county, the property and plant will become subject to the lien of any outstanding UE first mortgage bond indenture.

See Note 15 – Commitments and Contingencies to our financial statements under Part II, Item 8, of this report for information on mechanics’ liens filed against CILCO’s Duck Creek plant.

 

ITEM 3. LEGAL PROCEEDINGS.

We are involved in legal and administrative proceedings before various courts and agencies with respect to matters that arise in the ordinary course of business, some of which involve substantial amounts of money. We believe that the final disposition of these proceedings, except as otherwise disclosed in this report, will not have a material adverse effect on our results of operations, financial position, or liquidity. Risk of loss is mitigated, in some cases, by insurance or contractual or statutory indemnification. We believe that we have established appropriate reserves for potential losses.

For additional information on legal and administrative proceedings, see Rates and Regulation under Item 1, Business, and Item 1A, Risk Factors, above. See also Liquidity and Capital Resources and Regulatory Matters in Management’s Discussion and Analysis of Financial Condition and Results of Operations under Part II, Item 7, and Note 2 – Rate and Regulatory Matters, and Note 15 – Commitments and Contingencies to our financial statements under Part II, Item 8, of this report.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

 

OVERVIEW

Ameren Executive Summary

Operations

In 2008 and early 2009, we were able to successfully execute on key aspects of our long-term strategic plan. Our strategic plan calls for generation excellence and improvement of customer service and satisfaction. UE’s Callaway nuclear plant completed its first-ever breaker-to-breaker run and completed a plant record 28-day refueling and maintenance outage in the fall of 2008. In addition, the equivalent availability for UE’s coal-fired generating units was a solid 88% as compared to 89% in 2007. Ameren’s Non-rate-regulated Generation business segment set new generation records, producing approximately 31 million total megawatthours, as equivalent availability for its coal-fired units was 85% compared to 81% in 2007.

Amidst the economic challenges facing us and our nation, we have remained focused on our customers and have made significant investments in our energy infrastructure to improve overall reliability and customer satisfaction. In Missouri, through UE’s Power On reliability program, we buried more than 100 miles of electric line, trimmed trees along more than 6,500 miles of overhead line, tested nearly 100,000 wood utility poles, and inspected more than 8,000 miles of electric line. In Illinois, we targeted the worst-performing circuits and aggressively trimmed trees in Illinois Regulated’s 40,000 square-mile territory and continued to automate its transmission system to elevate its reliability. We believe that high-quality customer service is essential to earning solid returns in our rate-regulated businesses.

In Missouri, UE received approval of an electric rate increase in January 2009 with new rates effective March 1, 2009. The authorized increase in annual electric revenues is approximately $162 million based on a 10.76% return on equity. The MoPSC rate order authorized a FAC, as well as a vegetation management and infrastructure inspection cost tracking mechanism. The FAC and tracking mechanisms improve UE’s ability to continue to invest in its infrastructure so that UE will be able to meet its customers’ expectations for safe and reliable service.

In Illinois, the ICC authorized in September 2008 new electric and gas rates for the Ameren Illinois Utilities effective October 1, 2008. These new rates provide approximately $161 million in additional annual revenue based on allowed returns on equity of nearly 10.7%. The ICC also approved an increase in the fixed non-volumetric monthly charge for natural gas residential and commercial customers such that the Ameren Illinois Utilities now recover 80% of delivery service costs through this charge versus the prior 53%. The remainder is recovered through volume-based charges. This will make our gas utility earnings less sensitive to volumetric swings.

Earnings

Ameren reported net income of $605 million, or $2.88 per share, for 2008 compared with net income of $618 million, or $2.98 per share, in 2007. The decline in earnings in 2008 versus 2007 was principally due to higher fuel and related transportation prices, increased spending on utility distribution system reliability, higher plant operations and maintenance costs, milder weather, and net unrealized mark-to-market losses on nonqualifying hedges, among other things.

Those items more than offset the positive items. The positive items included improved generating plant output and higher realized margins from Non-rate-regulated Generation operations, the absence of costs in 2008 that were incurred in January 2007 associated with electric outages caused by severe ice storms and the amount of these costs that UE will recover as a result of an accounting order issued by the MoPSC, the reduced impact in 2008 of the Illinois electric settlement agreement, the absence in 2008 of the March 2007 FERC order that resettled costs among MISO market participants retroactive to 2005 that was recorded in 2007 and subsequent recovery of a portion of these costs in 2008 through a MoPSC order, net increases in electric and natural gas rates, and a 2008 lump-sum settlement payment from a coal supplier for expected higher fuel costs in 2009 as a result of a premature mine closure and contract termination, among other things.

Liquidity

Cash flows from operations of $1.5 billion in 2008 at Ameren, along with other funds, were used to pay dividends to common shareholders of $534 million and to partially fund capital expenditures of $1.9 billion. The remaining capital expenditures were primarily funded with debt.

We have taken actions to build on our financial strength and enhance our financial flexibility in light of the current difficult economic and capital and credit market conditions. These actions included the February 2009 decision of Ameren’s board of directors to reduce its common dividend and accessing the capital markets to increase our available liquidity, as well as making significant reductions in our 2008 and projected 2009 spending plans while still meeting our reliability, environmental, and safety objectives.

Outlook

The global capital and credit markets experienced extreme volatility and disruption in 2008, and we expect those conditions to continue throughout 2009. We believe that the disruption in the capital and credit markets will further weaken global economic conditions. These weak economic conditions will likely result in volatility in the power and commodity markets, greater risk of defaults by our counterparties, weaker customer sales growth, particularly with respect to industrial sales, higher bad debt expense and possible impairment of goodwill and long-lived assets, among other things.

Over the next few years, we continue to expect to make significant investments in our electric and natural gas infrastructure to improve reliability of our distribution systems and to comply with environmental requirements. From 2009 through 2011, we expect our rate-regulated rate base to grow approximately 9% per year. Earnings growth in our rate-regulated businesses is expected to come from updating existing customer rates to reflect these investments and the current levels of costs UE and the Ameren Illinois Utilities are experiencing. We consider the 2008 and 2009 Illinois and Missouri rate orders to be constructive. However, the returns that UE and the Ameren Illinois Utilities expect to earn in 2009 are below levels allowed by the respective state utility commissions in their last rate orders. The new rates were based on historic test year data and 2009 costs are expected to be higher than the levels recovered in rates. This is especially true of financing costs in Illinois, where sharply higher debt financing costs, which were incurred after our rate cases were filed, are not being recovered in rates. UE and the Ameren Illinois Utilities will file more frequent rate cases requesting moderate rate increases, as well as continue to seek appropriate cost recovery and tracker mechanisms to mitigate regulatory lag.

In addition, we will continue to optimize Ameren’s Non-rate-regulated Generation’s assets, focusing on improving the output of these plants and related energy marketing. We believe Non-rate-regulated Generation’s plants will be well positioned for earnings growth in the future should energy prices improve.

We will incur significant costs in future years to comply with existing federal EPA and state regulations regarding SO2, NOx, and mercury emissions from coal-fired power plants. Between 2009 and 2018, Ameren expects that certain Ameren Companies will be required to invest between $4.5 billion and $5.5 billion to retrofit their coal-fired power plants with pollution control equipment. Any pollution control investments will result in decreased plant availability during construction and significantly higher ongoing operating expenses. Approximately 50% of this investment is expected to be in our Missouri Regulated operations, and it is therefore expected to be recoverable from ratepayers.

Future initiatives regarding greenhouse gas emissions and global warming are subject to active consideration in the U.S. Congress. President Obama supports an economy-wide cap-and-trade greenhouse gas reduction program that would reduce emissions to 1990 levels by 2020 and to 80% below 1990 levels by 2050. President Obama has also indicated support for auctioning 100% of the emission allowances to be distributed under the legislation. Although we cannot predict the date of enactment or the requirements of any global warming legislation or regulations, it is likely that some form of federal greenhouse gas legislation or regulations will become law during President Obama’s administration. Potential impacts from proposed legislation could vary depending upon proposed CO2 emission limits, the timing of implementation of those limits, the method of allocating allowances, and provisions for cost containment measures.

 

Future federal and state legislation or regulations that mandate limits on the emission of greenhouse gases would result in significant increases in capital expenditures and operating costs, which, in turn, could lead to increased liquidity needs and higher financing costs. Excessive costs to comply with future legislation or regulations might force UE, Genco, CILCO (through AERG) and EEI and other similarly-situated electric power generators to close some coal-fired facilities and could lead to possible impairment of assets. As a result, mandatory limits could have a material adverse impact on Ameren’s, UE’s, Genco’s, CILCO’s (through AERG) and EEI’s results of operations, financial position, or liquidity.

General

Ameren, headquartered in St. Louis, Missouri, is a public utility holding company under PUHCA administered by FERC. Ameren’s primary assets are the common stock of its subsidiaries. Ameren’s subsidiaries are separate, independent legal entities with separate businesses, assets and liabilities. These subsidiaries operate rate-regulated electric generation, transmission and distribution businesses, rate-regulated natural gas transmission and distribution businesses, and non-rate-regulated electric generation businesses in Missouri and Illinois, as discussed below. Dividends on Ameren’s common stock and the payment of other expenses by the Ameren and CILCORP holding companies are dependent on distributions made to it by its subsidiaries. See Note 1 – Summary of Significant Accounting Policies to our financial statements under Part II, Item 8, of this report for a detailed description of our principal subsidiaries.

RESULTS OF OPERATIONS

Earnings Summary

Our results of operations and financial position are affected by many factors. Weather, economic conditions, and the actions of key customers or competitors can significantly affect the demand for our services. Our results are also affected by seasonal fluctuations: winter heating and summer cooling demands. The vast majority of Ameren’s revenues are subject to state or federal regulation. This regulation has a material impact on the price we charge for our services. Non-rate-regulated Generation sales are also subject to market conditions for power. We principally use coal, nuclear fuel, natural gas, and oil for fuel in our operations. The prices for these commodities can fluctuate significantly due to the global economic and political environment, weather, supply and demand, and many other factors. We do have natural gas cost recovery mechanisms for our Illinois and Missouri gas delivery businesses and purchased power cost recovery mechanisms for our Illinois electric delivery businesses. As part of the electric rate order issued by the MoPSC on January 27, 2009, UE was granted permission to put in place a FAC, which was effective March 1, 2009. See Note 2 – Rate and Regulatory Matters to our financial statements under Part II, Item 8, for a discussion of the January 27, 2009, MoPSC order in UE’s electric rate proceeding. Fluctuations in interest rates and conditions in the capital and credit markets affect our cost of borrowing and our pension and postretirement benefits costs. We employ various risk management strategies to reduce our exposure to commodity risk and other risks inherent in our business. The reliability of our power plants and transmission and distribution systems, the level of purchased power costs, operating and administrative costs, and capital investment are key factors that we seek to control to optimize our results of operations, financial position, and liquidity.

Ameren’s net income was $605 million ($2.88 per share) for 2008, $618 million ($2.98 per share) for 2007, and $547 million ($2.66 per share) for 2006.

Ameren’s net income decreased $13 million and earnings per share decreased 10 cents in 2008 compared with 2007. Net income increased in the Non-rate-regulated Generation segment by $71 million in 2008 compared to 2007, while net income in the Missouri Regulated and Illinois Regulated segments decreased by $47 million and $15 million, respectively. Other net income decreased $22 million in 2008 compared with 2007, primarily because of net unrealized mark-to-market losses on nonqualifying hedges mainly related to fuel-related transactions and reduced interest and dividend income.

Compared with 2007 earnings, 2008 earnings were negatively affected by:

 

Ÿ  

higher fuel and related transportation prices, excluding net mark-to-market losses on fuel-related transactions (27 cents per share);

Ÿ  

increased distribution system reliability expenditures (16 cents per share);

Ÿ  

higher plant operations and maintenance expenses (16 cents per share);

Ÿ  

unfavorable weather conditions (estimated at 16 cents per share);

Ÿ  

net unrealized mark-to-market losses on nonqualifying hedges (11 cents per share);

Ÿ  

higher financing costs (10 cents per share);

Ÿ  

asset impairment charges recorded during 2008 to adjust the carrying value of CILCO’s (through AERG) Indian Trails and Sterling Avenue generation facilities to their estimated fair values as of December 31, 2008 (6 cents per share);

Ÿ  

increased depreciation and amortization expense (6 cents per share);

Ÿ  

the absence in 2008 of the reversal, recorded in 2007, of the Illinois Customer Elect electric rate increase phase-in plan accrual (5 cents per share);

Ÿ  

higher labor and employee benefit costs (5 cents per share); and

Ÿ  

higher bad debt expenses (3 cents per share).

Compared with 2007 earnings, 2008 earnings were favorably affected by:

 

Ÿ  

higher realized electric margins in the Non-rate-regulated Generation segment;

Ÿ  

the absence of costs in 2008 that were incurred in January 2007 associated with electric outages caused by severe ice storms and the amount of these costs that UE will recover as a result of an accounting order issued by the MoPSC, which was recorded as a regulatory asset in 2008 (16 cents per share);

Ÿ  

the reduced impact in 2008 of the electric rate relief and customer assistance programs provided to certain Ameren Illinois Utilities electric customers under the Illinois electric settlement agreement (13 cents per share);

Ÿ  

the absence in 2008 of a March 2007 FERC order that resettled costs among MISO market participants retroactive to 2005 that was recorded in 2007 and the subsequent recovery of a portion of these costs in 2008, through a MoPSC order (10 cents per share);

Ÿ  

higher electric and natural gas delivery service rates in the Illinois Regulated segment pursuant to the ICC consolidated rate order for CIPS, CILCO, and IP issued in September 2008 (9 cents per share);

Ÿ  

a settlement agreement with a coal mine owner reached in June 2008 that reimbursed Genco, in the form of a lump-sum payment, for increased costs for coal and transportation that it expects to incur in 2009 due to the premature closure of an Illinois mine at the end of 2007 (8 cents per share);

Ÿ  

higher electric rates, lower depreciation expense and decreased income tax expense in the Missouri Regulated segment pursuant to the MoPSC electric rate order for UE issued in May 2007 (8 cents per share); and

Ÿ  

the reduced impact of the Callaway nuclear plant refueling and maintenance outage in 2008, as

compared with the prior-year refueling and maintenance outage (4 cents per share).

The cents per share information presented above is based on average shares outstanding in 2007.

Ameren’s net income increased $71 million and earnings per share increased 32 cents in 2007 compared with 2006.

Compared with 2006 earnings, 2007 earnings were favorably affected by:

 

Ÿ  

higher margins in the Non-rate-regulated Generation segment due to the replacement of below-market power sales contracts, which expired in 2006, with higher-priced contracts;

Ÿ

 

higher electric rates, lower depreciation expense, decreased income tax expense and $5 million in SO2 emission allowance sales in the Missouri Regulated segment pursuant to the MoPSC electric rate order for UE issued in May 2007 (21 cents per share);

Ÿ  

decreased costs associated with outages caused by severe storms (17 cents per share);

Ÿ  

the absence of costs in 2007 that were incurred in 2006 related to the reservoir breach at UE’s Taum Sauk plant (15 cents per share); and

Ÿ  

favorable weather conditions (estimated at 14 cents per share).

 

Compared with 2006 earnings, 2007 earnings were negatively affected by:

 

Ÿ  

the combined effect of the elimination of the Ameren Illinois Utilities’ bundled electric tariffs, implementation of new delivery service tariffs effective January 2, 2007, and the expiration of below-market power supply contracts;

Ÿ  

higher fuel and related transportation prices (31 cents per share);

Ÿ  

electric rate relief and customer assistance programs provided to certain Ameren Illinois Utilities’ electric customers under the Illinois electric settlement agreement (21 cents per share);

Ÿ

Ÿ  

higher financing costs (17 cents per share);

Ÿ  

lower emission allowance sales (16 cents per share);

Ÿ  

increases in distribution system reliability expenditures (15 cents per share);

Ÿ  

reduced gains on the sale of noncore properties, including leveraged leases (15 cents per share);

Ÿ  

increased depreciation and amortization expense (13 cents per share);

Ÿ  

a planned refueling and maintenance outage at UE’s Callaway nuclear plant net of an unplanned outage at Callaway in 2006 (9 cents per share); and

Ÿ  

higher bad debt expenses (8 cents per share).


 

The cents per share information presented above is based on average shares outstanding in 2006.

Because it is a holding company, Ameren’s net income and cash flows are primarily generated by its principal subsidiaries: UE, CIPS, Genco, CILCORP and IP. The following table presents the contribution by Ameren’s principal subsidiaries to Ameren’s consolidated net income for the years ended December 31, 2008, 2007 and 2006:

Margins

The following table presents the favorable (unfavorable) variations in the registrants’ electric and gas margins from the previous year. Electric margins are defined as electric revenues less fuel and purchased power costs. Gas margins are defined as gas revenues less gas purchased for resale. The table covers the years ended December 31, 2008, 2007, and 2006. We consider electric, interchange and gas margins useful measures to analyze the change in profitability of our electric and gas operations between periods. We have included the analysis below as a complement to the financial information we provide in accordance with GAAP. However, these margins may not be a presentation defined under GAAP, and they may not be comparable to other companies’ presentations or more useful than the GAAP information we provide elsewhere in this report.
