PART I

The terms "we," "our," "us," "Atmos" and "Atmos Energy" refer to Atmos Energy Corporation and its subsidiaries, unless the context suggests otherwise. The abbreviations "Mcf," "MMcf" and "Bcf" mean thousand cubic feet, million cubic feet and billion cubic feet.

 
ITEM 1. BUSINESS

OVERVIEW

Atmos Energy Corporation and its subsidiaries are engaged primarily in the natural gas utility business as well as certain natural gas non-utility businesses. We distribute natural gas through sales and transportation arrangements to approximately 1.7 million residential, commercial, public authority and industrial customers through our six regulated utility divisions, which cover service areas located in the following 12 states: Colorado, Georgia, Illinois, Iowa, Kansas, Kentucky, Louisiana, Mississippi, Missouri, Tennessee, Texas and Virginia. In addition, we transport natural gas for others through our distribution system.

Through our non-utility businesses, we provide natural gas management and marketing services to industrial customers, municipalities and other local gas distribution companies in 18 states. We also supplement natural gas used by our customers through natural gas storage fields that we own or hold an interest in and which are located in Kansas, Kentucky, Louisiana and Mississippi. We market natural gas to industrial and agricultural customers primarily in west Texas and to industrial customers in Louisiana. Finally, we construct electric power generating plants and associated facilities to meet peak load demands and lease or sell them to municipalities and industrial customers.

Our operations are divided into three segments:

- the utility segment, which includes our related natural gas distribution and sales operations,

- the natural gas marketing segment, which includes a variety of natural gas management services and

- the other non-utility segment, which includes our storage services and our electric power plant construction and leasing services.

Financial information relating to our operating segments is contained in Note 17 to the consolidated financial statements.

STRATEGY

Our overall strategy is to:

- accelerate growth through profitable acquisitions;

- improve the quality and consistency of earnings growth, while operating the natural gas utility and non-utility businesses exceptionally well and

- enhance and strengthen a culture built on our core values.

Over the last five years, we have accelerated our growth through several acquisitions including our acquisition of the remaining 55 percent interest in Woodward Marketing, L.L.C. that we did not already own in April 2001, the assets of Louisiana Gas Service Company (LGS) in July 2001 and Mississippi Valley Gas Company (MVG) in December 2002.

We have experienced 20 consecutive years of increasing dividends and consistent earnings growth after giving effect to our mergers. We have achieved this record of growth while operating our utility operations efficiently by managing our operating and maintenance expense; leveraging our technology, such as our 24 hour call center, to achieve more efficient operations; focusing on regulatory rate proceedings to increase revenue as our costs increased; mitigating weather-related risks through weather-normalized rates in some jurisdictions and disposing of non-growth assets. Additionally, we have strengthened our non-utility business

1

by essentially eliminating speculative trading activities and actively pursing opportunities to increase the amount of storage available to us to help mitigate the effects of weather on our trading activities.

Our core values include focusing on our employees and customers while conducting our business with honesty and integrity. We are strengthening our culture through continuous communication with our employees and enhanced training.

UTILITY SEGMENT

We operate our utility segment through six regulated natural gas utility divisions. Effective October 1, 2002, we united our gas distribution utility operations under the Atmos Energy brand. The following presents our six natural gas utility divisions and their former operating names:

- Atmos Energy Colorado-Kansas Division (formerly Greeley Gas Company),

- Atmos Energy Kentucky Division (formerly Western Kentucky Gas Company),

- Atmos Energy Louisiana Division (formerly Atmos Energy Louisiana Gas Company),

- Atmos Energy Mid-States Division (formerly United Cities Gas Company),

- Atmos Energy Texas Division (formerly Energas Company) and

- Mississippi Valley Gas Company Division (acquired in December 2002).

Our natural gas utility distribution business is seasonal and dependent on weather conditions in our service areas. Gas sales to residential and commercial customers are greater during the winter months than during the remainder of the year. The volumes of gas sales during the winter months will vary with the temperatures during these months. The seasonal nature of our sales to residential and commercial customers is partially offset by our sales in the spring and summer months to our agricultural customers in Texas, Colorado and Kansas who use natural gas to operate irrigation equipment.

In addition to weather, our revenues are affected by the cost of natural gas and economic conditions in the areas that we serve. Higher gas costs, which we are generally able to pass through to our customers under purchased gas adjustment clauses, may cause customers to conserve, or, in the case of industrial customers, to use alternative energy sources.

The effects of weather that is above or below normal are partially offset through weather normalization adjustments (WNA) in certain service areas. WNA allows us to increase the base rate portion of customers' bills when weather is warmer than normal and decrease the base rate when weather is colder than normal. As of September 30, 2003, we have WNA in the following service areas for the following periods, which cover approximately 658,000 or 39 percent of our meters in service:

 

Tennessee...................................................  November -- April
Georgia.....................................................  October -- May
Mississippi.................................................  November -- May
Kentucky....................................................  November -- April
Kansas(1)...................................................  October -- May
Amarillo, Texas(1)..........................................  October -- May


(1) Effective for the 2003-2004 winter heating season

We receive gas deliveries in our utility operations through 36 pipeline transportation companies, both interstate and intrastate, to satisfy our sales market requirements. The pipeline transportation agreements are firm and many of them have "pipeline no-notice" storage service which provides for daily balancing between system requirements and nominated flowing supplies. These agreements have been negotiated with the shortest term necessary while still maintaining our right of first refusal.

2

We purchase our gas supply from various producers and marketers. Supply arrangements are contracted on a firm basis with various terms at market prices. The firm supply consists of both base load and swing supply quantities. Base load quantities are those that flow at a constant level throughout the month and swing supply quantities provide the flexibility to change daily quantities to match increases or decreases in requirements related to weather conditions. Except for local production purchases, we select suppliers through a competitive bidding process by requesting proposals from suppliers that have demonstrated that they can provide reliable service. We select these suppliers based on their ability to deliver gas supply to our designated firm pipeline receipt points at the lowest cost. Our major suppliers during fiscal 2003 were Anadarko Energy Services, BP Energy Company, Cinergy Marketing and Trading, Duke Energy Trading and Marketing, ONEOK Energy Marketing, Pioneer Natural Resources, Prior Energy Corporation, Tenaska Marketing and Woodward Marketing, L.L.C., one of our natural gas marketing subsidiaries. We do not anticipate problems with obtaining additional gas supply as needed for our customers.

We also contract for storage service in underground storage facilities on many of the interstate pipelines serving us.

Our distribution systems have experienced aggregate peak day deliveries of approximately 2.0 Bcf per day. To maintain our deliveries to high priority customers, we have the ability and have exercised our right, to curtail deliveries to certain customers under the terms of interruptible contracts, applicable state statutes or regulations.

The following is a brief description of our six natural gas utility divisions. Additional information for each division is presented under the caption "Operating Statistics".

Atmos Energy Colorado-Kansas Division. Our Colorado-Kansas Division operates in Colorado, Kansas and the southwestern corner of Missouri and is regulated by each respective state's public service commission with respect to accounting, rates and charges, operating matters and the issuance of securities. We operate under terms of non-exclusive franchises granted by the various cities. In May 2003, we received approval for WNA in Kansas which will be effective October through May of each year beginning with the 2003-2004 winter heating season. Colorado Interstate Gas Company, Williams Pipeline-Central, Public Service Company of Colorado and Northwest Pipeline are the principal transporters of the Colorado-Kansas Division's gas supply requirements. Additionally, the Colorado-Kansas Division purchases substantial volumes from producers that are connected directly to its distribution system.

Atmos Energy Kentucky Division. Our Kentucky Division operates in Kentucky and is regulated by the Kentucky Public Service Commission, which regulates utility services, rates, issuance of securities and other matters. We operate in the various incorporated cities pursuant to non-exclusive franchises granted by these cities. Sales of natural gas for use as vehicle fuel in Kentucky are unregulated. We have been operating under a performance-based rate program since July 1998, which was extended for another four years in 2002. Under the performance-based program, we and our customers jointly share in any actual gas cost savings achieved when compared to pre-determined benchmarks. Our rates are also subject to WNA. The Kentucky Division's gas supply is delivered primarily by Williams Pipeline-Texas Gas, Tennessee Gas, Trunkline, Midwestern Pipeline and ANR.

Atmos Energy Louisiana Division. Our Louisiana Division operates in Louisiana and includes the operations of the assets of Louisiana Gas Service Company acquired in July 2001 and our previously existing Trans La Division. Our Louisiana Division is regulated by the Louisiana Public Service Commission, which regulates utility services, rates and other matters. We operate most of our service areas pursuant to a non-exclusive franchise granted by the governing authority of each area. Direct sales of natural gas to industrial customers in Louisiana, who use gas for fuel or in manufacturing processes, and sales of natural gas for vehicle fuel are exempt from regulation. Louisiana Intrastate Gas Company, Acadian Pipeline, Gulf South and Williams Pipeline-Texas Gas pipelines provide most of the Louisiana Division's natural gas requirements.

Atmos Energy Mid-States Division. Our Mid-States Division operates in Georgia, Illinois, Iowa, Missouri, Tennessee and Virginia. In each of these states, our rates, services and operations as a natural gas distribution company are subject to general regulation by each state's public service commission. We operate

3

in each community, where necessary, under a franchise granted by the municipality for a fixed term of years. In Tennessee and Georgia, we have WNA and a performance-based rate program, which provides incentives for us to find ways to lower costs and share the cost savings with our customers. Our Mid-States Division is served by 13 interstate pipelines; however, the majority of the volumes are transported through East Tennessee Pipeline, Southern Natural Gas, Tennessee Gas Pipeline and Columbia Gulf.

Atmos Energy Texas Division. Our Texas Division operates in Texas in three primary service areas: the Amarillo service area, the Lubbock service area and the West Texas service area. The governing body of each municipality we serve has original jurisdiction over all utility rates, operations and services within its city limits, except with respect to sales of natural gas for vehicle fuel and agricultural use. We operate pursuant to non-exclusive franchises granted by the municipalities we serve, which are subject to renewal from time to time. The Railroad Commission of Texas has exclusive appellate jurisdiction over all rate and regulatory orders and ordinances of the municipalities and exclusive original jurisdiction over rates and services to customers not located within the limits of a municipality. In August 2003, the Texas Division received approval from the City of Amarillo, Texas, for WNA for its Amarillo service area, which will be effective October through May of each year, beginning with the 2003-2004 winter heating season. Our Texas Division receives transportation service from ONEOK Pipeline. In addition, the Texas Division purchases a significant portion of its natural gas supply from Pioneer Natural Resources which is connected directly to our Amarillo, Texas distribution system.

Mississippi Valley Gas Company Division. Our Mississippi Valley Gas Company Division, acquired in December 2002, operates in Mississippi and is regulated by the Mississippi Public Service Commission with respect to rates, services and operations. We operate under non-exclusive franchises granted by the municipalities we serve. Since the acquisition, we have been operating under a rate structure that allows us over a five year period to recover a portion of our integration costs associated with the acquisition, and operations and maintenance costs in excess of an agreed-upon benchmark. In addition, we are required to file for rate adjustments based on our expenses every six months. We also have WNA in Mississippi. This division's gas supply is delivered by Gulf South Pipeline Company, Tennessee Gas Pipeline Company, Southern Natural Gas Company, Texas Eastern Transmission, Texas Gas Transmission LLC, Trunkline Gas Co. LLC and Enbridge Marketing LP.

NATURAL GAS MARKETING SEGMENT

Our natural gas marketing and other non-utility segments, which are organized under Atmos Energy Holdings, Inc., have operations in 18 states. Through September 30, 2003, Atmos Energy Marketing, LLC, together with its wholly-owned subsidiaries Woodward Marketing, L.L.C. and Trans Louisiana Industrial Gas Company, Inc., comprised our natural gas marketing segment. Effective October 1, 2003, our natural gas marketing segment was reorganized. The operations of Atmos Energy Marketing, L.L.C and Trans Louisiana Industrial Gas Company, Inc were merged into Woodward Marketing, L.L.C., which was renamed Atmos Energy Marketing, LLC (AEM).

We acquired a 45 percent interest in Woodward Marketing, L.L.C. in July 1997 as a result of the merger of Atmos and United Cities Gas Company, which had acquired that interest in May 1995. In April 2001, we acquired the remaining 55 percent interest that we did not own for 1,423,193 restricted shares of our common stock.

AEM provides a variety of natural gas management services to municipalities, natural gas utility systems and industrial natural gas consumers primarily in the southeastern and midwestern states and to our Colorado-Kansas, Kentucky, Louisiana and Mid-States divisions. These services primarily consist of furnishing natural gas supplies at fixed and market-based prices, contract negotiation and administration, load forecasting, gas storage acquisition and management services, transportation services, peaking sales and balancing services, capacity utilization strategies and gas price management through the use of derivative products. In providing these services, AEM generates income from its utility, municipal and industrial customers through negotiated prices based on the volume of gas supplied to the customer. AEM also generates income by taking advantage of the difference between near-term gas prices and prices for future delivery as well as the daily movement of

4

gas prices by utilizing storage and transportation capacity that it controls. Finally, AEM supplies our regulated operations with a portion of our natural gas requirements on a competitive bid basis.

AEM's management of natural gas requirements involves the sale of natural gas and the management of storage and transportation supplies under contracts with customers generally having one to two year terms. At September 30, 2003, AEM had a total of 750 industrial customers and 206 municipal customers. AEM also sells natural gas to some of its industrial customers on a delivered burner tip basis under contract terms from 30 days to two years.

OTHER NON-UTILITY SEGMENT

Our other non-utility segment consists primarily of the operations of Atmos Pipeline and Storage, L.L.C. and Atmos Power Systems, Inc., which are wholly-owned subsidiaries of Atmos Energy Holdings, Inc. Through Atmos Pipeline and Storage, LLC, we own or have an interest in underground storage fields in Kansas, Kentucky and Louisiana. We use these storage facilities to help meet customer requirements during peak demand periods and to reduce the need to contract for additional pipeline capacity to meet customer demand during peak periods. We normally inject gas into pipeline storage systems and company owned storage facilities during the summer months and withdraw it in the winter months.

Through Atmos Power Systems, Inc. we construct and operate electric peaking power generating plants and associated facilities and may enter into agreements to either lease or sell these plants.

United Cities Propane Gas, Inc., a wholly-owned subsidiary of Atmos Energy Holdings, Inc., owns an approximate 19 percent membership interest in U.S. Propane L.P. (USP), a joint venture formed in February 2000 with other utility companies. As of September 30, 2003, USP owned all of the general partnership interest and approximately 26 percent of the limited partnership interest in Heritage Propane Partners, L.P. a publicly traded marketer of propane through a nationwide retail distribution network. Through our ownership in USP, we own an approximate five percent indirect interest in Heritage Propane Partners, L.P. On November 7, 2003, we announced that we and our utility partners had entered into an agreement to sell our interest in USP, including the general partnership and limited partnerships in Heritage Propane Partners, L.P., for $130.0 million. We expect to receive approximately $24.7 million and to record a $4.4 million pretax book gain upon closing of the transaction which is conditioned upon regulatory and other approvals.

Notes to preceding tables:

(1) The operational and statistical information includes the operations of LGS since the July 1, 2001 acquisition date and the operations of MVG since the December 3, 2002 acquisition date.

(2) A heating degree day is equivalent to each degree that the average of the high and the low temperatures for a day is below 65 degrees. The colder the climate, the greater the number of heating degree days. Heating degree days are used in the natural gas industry to measure the relative coldness of weather and to compare relative temperatures between one geographic area and another. Normal degree days are based on 30-year average National Weather Service data for selected locations. Degree day information for 2003, 2002 and 2001 is adjusted for service areas included in the Mid-States Division and the Kentucky Division which have weather normalized operations. Degree day information for 2003 is also adjusted for service areas included in the Mississippi Valley Gas Company Division which has weather normalized operations as well. Degree day information for 2000 and 1999 has not been adjusted for service areas with weather normalized operations as that information was not available.

(3) Sales volumes and revenues reflect segment operations, including intercompany sales and transportation amounts.

(4) These tables present data for our six natural gas utility divisions. Their operations include the regulated local distribution companies located in their respective service areas. The operations of LGS are included in our Louisiana Division since the July 1, 2001 acquisition date, and the operations of MVG are included in our Mississippi Valley Gas Company Division since the December 3, 2002 acquisition date.

(5) The number of utility employees excludes 504, 489, 480, 369 and 427 Atmos shared services employees and 88, 83, 62, 28 and 164 other segment employees in 2003, 2002, 2001, 2000 and 1999.

(6) Prior to August 2000, propane revenues and expenses were fully consolidated. Subsequent to August 2000, the results of our propane operations are shown on the equity basis.

(7) Through March 31, 2001 substantially all of our natural gas marketing revenues and expenses are shown on the equity basis. Beginning April 1, 2001 natural gas marketing revenues and expenses are fully consolidated.

REGULATION

Each of our utility divisions is regulated by various state or local public utility authorities. We are also subject to regulation by the United States Department of Transportation with respect to safety requirements in the operation and maintenance of our gas distribution facilities. Our distribution operations are also subject to various state and federal laws regulating environmental matters. From time to time we receive inquiries regarding various environmental matters. We believe that our properties and operations substantially comply with and are operated in substantial conformity with applicable safety and environmental statutes and regulations. There are no administrative or judicial proceedings arising under environmental quality statutes pending or known to be contemplated by governmental agencies which would have a material adverse effect on us or our operations. All of our environmental claims have arisen out of manufactured gas plant sites in Tennessee, Iowa and Missouri and mercury contamination sites in Kansas. These claims are more fully described in Note 13 to the consolidated financial statements.

RATEMAKING ACTIVITY

OVERVIEW

The method of determining regulated rates varies among the states in which our natural gas utility divisions operate. The regulators have the responsibility of ensuring that utilities under their jurisdiction operate in the best interests of customers while providing utility companies the opportunity to earn a reasonable return on investment. In a general rate case, the applicable regulatory authority, which is typically the state public utility commission, establishes rates which allow a utility company an opportunity to collect revenue from customers to recover the cost of providing utility service.

Rates established by regulatory authorities are adjusted for increases and decreases in our purchased gas cost through purchased gas adjustment mechanisms. Purchased gas adjustment mechanisms provide gas utility companies a method of recovering purchased gas costs on an ongoing basis without filing a rate case to address all of the utility's non-gas costs. These mechanisms are commonly utilized when regulatory authorities recognize a particular type of expense, such as purchased gas costs, that (i) is subject to significant price fluctuations compared to the utility's other costs, (ii) represents a large component of the utility's cost of service and (iii) is generally outside the control of the gas utility. There is no margin generated through purchased gas adjustments, but they do provide a dollar-for-dollar offset to increases or decreases in utility gas costs. Although substantially all of our utility sales to our customers fluctuate with the cost of gas that we purchase, utility gross profit (which is defined as operating revenues less purchased gas cost) is generally not affected by fluctuations in the cost of gas due to the purchased gas adjustment mechanism. Additionally, certain jurisdictions have introduced performance-based ratemaking adjustments to provide incentives to natural gas utilities to minimize purchased gas costs through improved storage management and use of financial hedges to lock in gas costs. Under the performance-based ratemaking adjustment, purchased gas costs savings are shared between the utility and the customer.

RECENT RATEMAKING ACTIVITY

Approximately 97 percent, 96 percent and 97 percent of our utility revenues in the fiscal years ended September 30, 2003, 2002 and 2001 were derived from sales at rates set by or subject to approval by local or state authorities. Net annual rate increases totaling $18.6 million and $6.4 million became effective in fiscal 2003 and fiscal 2001. There were no rate increases which became effective in fiscal 2002.

(a) The Kansas Corporation Commission is scheduled to conduct a public hearing on this case in December 2003.

(b) No requested amounts are presented because either (1) we file periodic requests for rate adjustments based upon our actual expenses in accordance with the respective state commission's rules or (2) the commission's ruling was not the result of a rate filing initiated by us. See further information in the following discussion.

(c) In 2002, we submitted our 2001 rate stabilization filing and received tariff revisions which resulted in an increase in annual revenues of $0.5 million during the first 24-month period. Subsequent to the first 24-month period, adjusted rates will provide an increase in annual revenues of $0.4 million.

(d) In 2002, we submitted our 2001 rate stabilization filing and received tariff revisions which resulted in an increase in annual revenues of $15.3 million during the first 24-month period. Subsequent to the first 24-month period, adjusted rates will provide an increase in annual revenues of $11.9 million.

(e) Effective April 1, 1999, the Tennessee Regulatory Authority approved a performance-based ratemaking mechanism related to gas procurement and gas transportation activities. Effective May 1, 2002, the Georgia Public Service Commission renewed our performance-based ratemaking program. The impacts of these rulings are described in greater detail below.

(f) This case was filed in September 2003 and is pending review by the affected cities.

(g) This case was filed in October 2003 and is pending review by the City of Lubbock.

(h) In October 2003, the Mississippi Public Service Commission issued a final ruling which denied our May 2003 request for a rate adjustment. We are currently considering our response to the Commission's ruling.

Atmos Energy Colorado-Kansas Division. In May 2003, the Colorado-Kansas Division filed a rate case with the Kansas Corporation Commission for approximately $7.4 million in additional annual revenues. The Kansas Corporation Commission is scheduled to conduct a public hearing on the case in December 2003. Additionally, in May 2003, we received approval for WNA in Kansas which will be effective October through May of each year beginning with the 2003-2004 winter heating season.

In November 2000, the Colorado-Kansas Division filed a rate case with the Colorado Public Utilities Commission for approximately $4.2 million in additional annual revenues. In May 2001, we received an increase in annual revenues of approximately $2.8 million from the Colorado Public Utilities Commission. The new rates went into effect on May 4, 2001.

Atmos Energy Kentucky Division. On March 25, 2002, the Kentucky Commission issued an Order approving a four year extension, effective April 1, 2002, of the Performance-based Ratemaking mechanism related to gas procurement and gas transportation activities filed by the Kentucky Division. The Performance-based Ratemaking mechanism is incorporated into the Kentucky Division's gas cost adjustment clause and provides for the sharing of purchased gas cost savings between our customers and us. We recognized other income of $1.3 million, $1.1 million and $0.2 million under the Kentucky Performance-based-ratemaking mechanism in fiscal years 2003, 2002 and 2001.

In May 1999, the Kentucky Division requested from the Kentucky Public Service Commission a $14.1 million increase in revenues, a weather normalization adjustment and changes in rate design to shift a portion of revenues from commodity charges to fixed rates. In December 1999, the Kentucky Commission granted an increase in annual revenues of approximately $9.9 million. The new rates were effective for services rendered on or after December 21, 1999. In addition, the Kentucky Commission approved a five-year pilot program for weather normalization beginning in November 2000.

Atmos Energy Louisiana Division. In October 2002, Atmos received written notification from the Executive Secretary of the Louisiana Public Service Commission that he was asserting that a monthly facilities fee of approximately $0.6 million charged since July 2001 to Atmos by Trans Louisiana Gas Pipeline, Inc., a wholly-owned subsidiary of Atmos, pursuant to a contract between the parties, was excessive. The Executive Secretary asserted that all monthly facilities fees in excess of approximately $0.1 million from July 2001 should be refunded to ratepayers with interest. In September 2003, an agreement was reached with the commission staff to allow Atmos to charge a facilities fee of approximately $0.5 million per month (subject to future escalation) beginning November 1, 2003 for a period of 14 years. No retroactive adjustments will be required under this agreement. On October 8, 2003, the commission unanimously voted in open session to approve the agreement.

In January and February 2002, our Louisiana Division submitted its 2001 Rate Stabilization filings to the Louisiana Public Service Commission for the two gas systems we operate in Louisiana. The Louisiana Public Service Commission audited the filings and found our earnings to be deficient and that rate adjustments were appropriate. Approved tariff revisions, which became effective November 1, 2002, will result in $15.3 million in additional revenues per year for our LGS System and $0.5 million for our Trans La System during the first 24-month period. Subsequent to the first 24-month period, adjusted rates will provide total annual revenue increases of $11.9 million for our LGS System and $0.4 million for our Trans La System. As a result of the actions taken by the Louisiana Public Service Commission, we have decreased the overall weather impact to our revenues in Louisiana.

In 2001, in connection with its review of our acquisition of Louisiana Gas Service, the Louisiana Public Service Commission approved a rate structure that requires us to share with the customers of Louisiana Gas Service cost savings that resulted from the acquisition. The shared cost savings will be the difference between operation and maintenance expense in any future year and the 1998 normalized expense for Louisiana Gas Service, indexed for inflation, annual changes in labor costs and customer growth. Beginning January 1, 2002, customers have been assured they will receive annual savings, which will be indexed for inflation, annual changes in labor costs and customer growth. The sharing mechanism will remain in place for 20 years subject to established modification procedures.

In June 1999, our Trans La operations were involved in a rate investigation before the Louisiana Public Service Commission, including the redesign of rates to mitigate the effects of warm winter weather. A decision was rendered by the Louisiana Commission in October 1999 that increased service charges associated with customer service calls and increased the monthly customer charges from $6 to $9, both effective November 1, 1999. While these changes are revenue neutral, they have mitigated the impact of warmer than normal winter weather on earnings. The decision also included a three-year rate stabilization clause which will allow the Trans La operations of our Louisiana Division's rates to be adjusted annually to allow us to earn a return on equity within certain ranges that will be monitored on an annual basis.

Atmos Energy Mid-States Division. Effective April 1, 1999, the Tennessee Regulatory Authority approved the Mid-States Division's request to continue its Performance-based Ratemaking mechanism related to gas procurement and gas transportation activities. The Tennessee Regulatory Authority revised the mechanism from the original two-year experimental period, by increasing the cap for incentive gains and/or losses to $1.25 million per year. Under this agreement, the mechanism has no expiration date and can be amended or cancelled by either the Mid-States Division or the Tennessee Regulatory Authority according to the provisions of the agreement. Similar to Tennessee, the Georgia Public Service Commission renewed our Performance-based Ratemaking program for an additional three years effective May 1, 2002. The gas purchase and capacity release mechanisms of the Performance-based Ratemaking mechanism are designed to provide us incentives to find innovative methods to lower gas costs to our customers. We recognized other income of $0.5 million, $0.4 million and $1.0 million in fiscal years 2003, 2002 and 2001 attributable to the Georgia and Tennessee Performance-based Ratemaking mechanisms.

In March 2001, the Mid-States Division and the Iowa Consumer Advocate Division of the Department of Justice reached an agreement for an annual rate reduction of $0.3 million relating to our Iowa operations. The rate reduction was effective in March 2001. Also in 2001, the Mid-States Division filed requests for accounting orders related to uncollectible delinquencies in three states. As a result, we were able to defer $1.5 million as a regulatory asset.

In February 2000, the Mid-States Division filed a rate case in Illinois with the Illinois Commerce Commission requesting an increase in annual revenues of approximately $3.1 million. After review by the Illinois Commerce Commission, we received an increase in annual revenues of approximately $1.4 million. The new rates went into effect on October 23, 2000 and are collected primarily through an increase in monthly customer charges.

In March 2000, the Mid-States Division filed a rate case in Virginia with the State Corporation Commission of the Commonwealth of Virginia requesting an increase in annual revenues of approximately $2.3 million. The State Corporation Commission of Virginia reviewed the filing to determine if it met the appropriate rules and regulations. In July 2000, we re-filed the case requesting an increase in revenues of approximately $2.1 million. The Commission accepted the revised filing. In April 2001, the Mid-States Division agreed to an annual rate reduction of $0.5 million effective beginning with the April 2001 billing cycle.

Atmos Energy Texas Division. In June 2003, the Texas Division filed a rate case in Amarillo, Texas, requesting a $5.1 million increase in annual revenues. In August 2003, the City of Amarillo, Texas approved an annual increase of approximately $2.8 million, which was effective for bills rendered on or after September 1, 2003. The increase was primarily comprised of an increase in monthly customer charges. The agreement with Amarillo also provided for changes in the rate structure to recover the cost of uncollectible accounts, adjustments to base rates to compensate for declining gas use per customer and provided WNA, which will be effective October through May, beginning in fiscal 2004.

In September 2003, the Texas Division filed a rate case in its West Texas System to request a $7.7 million increase in annual revenues and WNA for our residential, commercial and public-authority customers. The filing is pending review by the affected cities. In October 2003, the Texas Division filed a rate case in Lubbock to request a $3.0 million increase in annual revenues and WNA for our residential, commercial and public-authority customers. The filing is pending review by the City of Lubbock.

In August 1999, the Texas Division filed rate cases in its West Texas System cities and Amarillo, Texas, requesting rate increases of approximately $9.8 million and $4.4 million. The Texas Division received an increase in annual revenues of approximately $2.1 million in base rates plus an increase of $0.1 million in service charges in Amarillo, Texas, effective for bills rendered on or after January 1, 2000. The agreement with Amarillo also provided for changes in the rate structure to reduce the impact of warmer than normal weather and to improve the recovery of the actual cost of service calls. The Texas Division's request for its West Texas System cities was initially denied, and in March 2000 this decision was appealed to the Railroad Commission of Texas (Railroad Commission). Subsequently, 59 cities ratified a non-binding Settlement Agreement which capped the rate increase at $3.0 million and entitled the ratifying cities to accept a rate increase below $3.0 million in the event the Railroad Commission adopted a lesser increase for the non-ratifying cities. The remaining eight cities declined to participate in the settlement and a hearing with the Railroad Commission was held in August 2000. In December 2000, the Railroad Commission approved a settlement which increased annual revenues by approximately $3.0 million that covered all 67 cities served by the West Texas System effective December 1, 2000. In addition, the Railroad Commission approved a new rate design providing more protection from warmer than normal weather for our West Texas System.

Mississippi Valley Gas Company Division. The Mississippi Public Service Commission requires that we file for rate adjustments based on our expenses every six months. Typically, rate adjustments are filed in May and November of each year and the rate becomes effective in June and December. In October 2003, the Mississippi Public Commission issued a final order which denied our May 2003 request for a rate adjustment. We are currently considering our response to the Commission's ruling. Additionally, we filed our second semi-annual filing on November 5, 2003.

COMPETITION

Our utility operations are not currently in significant direct competition with any other distributors of natural gas to residential and commercial customers within our service areas. However, we do compete with other natural gas suppliers and suppliers of alternative fuels for sales to industrial and agricultural customers. We compete in all aspects of our business with alternative energy sources, including, in particular, electricity. Competition for residential and commercial customers is increasing. Promotional incentives, improved equipment efficiencies and promotional rates all contribute to the acceptability of electrical equipment. Electric utilities offer electricity as a rival energy source and compete for the space heating, water heating and cooking markets. The principal means to compete against alternative fuels is lower prices, and natural gas historically has maintained its price advantage in the residential, commercial and industrial markets. In addition, our Natural Gas Marketing segment competes with other natural gas brokers in obtaining natural gas supplies for customers.

EMPLOYEES

At September 30, 2003, we had 2,905 employees, consisting of 2,817 employees in our utility segment and 88 employees in our other segments. See "Operating Statistics -- Utility Sales and Statistical Data by Division" for the number of employees by division.

ITEM 2. PROPERTIES

DISTRIBUTION, TRANSMISSION AND RELATED ASSETS

Our utility segment owns an aggregate of 45,267 miles of underground distribution and transmission mains throughout our gas distribution systems. These mains are located on easements or rights-of-way which generally provide for perpetual use. We maintain our mains through a program of continuous inspection and repair and believe that our system of mains is in good condition.

Our utility segment also holds franchises granted by the incorporated cities and towns that we serve. At September 30, 2003, we held 651 franchises having terms generally ranging from five to 25 years. We believe that each of our franchises will be renewed.

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

INTRODUCTION

This section provides management's discussion of the financial condition, cash flows and results of operations of Atmos Energy Corporation with specific information on results of operations and liquidity and capital resources. It includes management's interpretation of our financial results, the factors affecting these results, the major factors expected to affect future operating results and future investment and financing plans. This discussion should be read in conjunction with the Company's consolidated financial statements and notes thereto.

CAUTIONARY STATEMENT FOR THE PURPOSES OF THE SAFE HARBOR UNDER THE PRIVATE
SECURITIES LITIGATION REFORM ACT OF 1995

The statements contained in this Annual Report on Form 10-K may contain "forward-looking statements" within the meaning of Section 21E of the Securities Exchange Act of 1934. All statements other than statements of historical fact included in this Report are forward-looking statements made in good faith by the Company and are intended to qualify for the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995. When used in this Report, or any other of the Company's documents or oral presentations, the words "anticipate," "expect," "estimate," "plans," "believes," "objective," "forecast," "goal" or similar words are intended to identify forward-looking statements. Such forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied in the statements relating to the Company's strategy, operations, markets, services, rates, recovery of costs, availability of gas supply and other factors. These risks and uncertainties include the following:
adverse weather conditions such as warmer than normal weather in the Company's utility service territories or colder than normal weather which could adversely affect our natural gas marketing activities; regulatory trends and decisions, including deregulation initiatives and the impact of rate proceedings before various state regulatory commissions; market risks beyond our control affecting our risk management activities including market liquidity, commodity price volatility and counterparty creditworthiness; national, regional and local economic conditions, limited access to financial markets; inflation and increased gas costs, including their effect on commodity prices for natural gas; increased competition; and other uncertainties, all of which are difficult to predict and many of which are beyond the control of the Company. Accordingly, while the Company believes these forward-looking statements to be reasonable, there can be no assurance that they will approximate actual experience or that the expectations derived from them will be realized. Further, the Company undertakes no obligation to update or revise any of its forward-looking statements whether as a result of new information, future events or otherwise.

FACTORS THAT MAY AFFECT OUR FUTURE PERFORMANCE

Our performance in the future will primarily depend on the results of our utility and natural gas marketing operations. Several factors exist that could influence Atmos' future financial performance, some of which are described below. They should be considered in connection with evaluating forward-looking statements contained in this report or otherwise made by or on behalf of us since these factors could cause actual results and conditions to differ materially from those projected in these forward-looking statements.

OUR OPERATIONS ARE WEATHER SENSITIVE.

Weather is one of the most significant factors influencing our performance. Our natural gas utility sales volumes and related revenues are correlated with heating requirements that result from cold winter weather. Our agricultural sales volumes are associated with the rainfall levels during the growing season in our west Texas irrigation market. However, weather normalized rates in effect in several of our jurisdictions should mitigate the adverse effects of warmer than normal weather on our utility operating results. Finally, sustained cold weather could adversely affect our natural gas marketing operations as we may be required to purchase gas at spot rates in a rising market to obtain sufficient volumes to fulfill some customer contracts.

24

OUR OPERATIONS ARE SUBJECT TO REGULATION WHICH CAN DIRECTLY IMPACT OUR
OPERATIONS.

Our natural gas utility business is subject to various regulated returns on its rate base in each of the 12 states in which we operate. We monitor the allowed rates of return, our effectiveness in earning such rates and initiate rate proceedings or operating changes as needed. In addition, in the normal course of the regulatory environment, assets are placed in service and historical test periods are established before rate cases can be filed. Once rate cases are filed, regulatory bodies have the authority to suspend implementation of the new rates while studying the cases. Because of this process, we must temporarily suffer the negative financial effects of having placed assets in service without the benefit of rate relief, which is commonly referred to as "regulatory lag". In addition, our debt and equity financing programs are also subject to approval by regulatory bodies in certain states, which could limit our ability to take advantage of favorable short-term market conditions.

Our business could also be affected by deregulation initiatives, including the development of unbundling initiatives in the natural gas industry. Unbundling is the separation of the provision and pricing of local distribution gas services into discrete components. It typically focuses on the separation of the distribution and gas supply components and the resulting opening of the regulated components of sales services to alternative unregulated suppliers of those services. Because of our enhanced technology and distribution system infrastructures, we believe that we are now positively positioned as unbundling evolves. Consequently, we expect there would be no significant adverse effect on our business should unbundling or further deregulation of the natural gas distribution service business occur.

Finally, contractual limitations could adversely affect our ability to withdraw gas from storage, which could cause us to purchase gas at spot prices in a rising market to obtain sufficient volumes to fulfill customer contracts. We seek to minimize this risk by increasing our storage capacity and enhancing the flexibility of our natural gas marketing contracts.

 

OUR OPERATIONS ARE EXPOSED TO MARKET RISKS THAT ARE BEYOND OUR CONTROL, WHICH
COULD RESULT IN FINANCIAL LOSSES.

Our risk management operations are subject to market risks beyond our control including market liquidity, commodity price volatility and counterparty creditworthiness. Market liquidity is affected by the number of trading partners in the market. As a result of the recent severe downturn in the natural gas marketing industry, the number of trading partners has been reduced, which could adversely impact the market liquidity for this industry and adversely affect our natural gas marketing operations.

Further, although we maintain a risk management control policy, we may not be able to completely offset the price risk associated with volatile gas prices or the risk in our gas trading activities which could lead to financial losses. Physical trading also introduces price risk on any net open positions at the end of each trading day, as well as a risk of loss resulting from intra-day fluctuations of gas prices and the potential for daily price movements between the time natural gas is purchased or sold for future delivery and the time the related purchase or sale is hedged. Although we manage our business to maintain no open positions, at times, limited net open positions related to our physical storage may occur on a short term basis. Net open positions may result in an adverse impact on our financial condition or results of operations if market prices react in an unfavorable manner.

Our utility segment uses a combination of storage and financial hedges to protect against volatility in gas prices and to help moderate the effects of higher customer accounts receivable caused by potentially higher gas prices. Our natural gas marketing segment manages margins and limits risk exposure on the sale of natural gas inventory or the offsetting fixed-price purchase or sale commitments for physical quantities of natural gas through the use of a variety of financial derivatives.

We could realize financial losses on these activities as a result of volatility in the market value of the underlying commodities or if a counterparty fails to perform under a contract.

Finally, the use of financial instruments to conduct our hedging and market risk activities subjects us to counterparty risk. Adverse changes in the creditworthiness of our counterparties could limit the level of

25

trading activities with these parties and increase the risk that these parties may not perform under a contract. We believe this risk is mitigated due to the large number of counterparties used in our risk management activities.

NATIONAL, REGIONAL AND LOCAL ECONOMIC CONDITIONS HAVE A DIRECT IMPACT ON OUR
OPERATIONS.

Our operations will always be affected by the conditions and overall strength of the national, regional and local economies, including interest rates, changes in the capital markets and increases in the costs of our primary commodity, natural gas. These factors impact the amount of residential, industrial and commercial growth in our service territories. Additionally, these factors could adversely impact our customer collections.

Further, AEM's operations are concentrated in the natural gas industry, and its customers and suppliers may be subject to economic risks affecting that industry. During 2003, AEM's credit risk increased due to higher natural gas prices as compared with the prior year. However, we believe this risk is mitigated because a larger percentage of our natural gas marketing business in the current year is with municipal customers (who typically are more creditworthy) as compared with the prior year.

THE EXECUTION OF OUR BUSINESS PLAN COULD BE AFFECTED BY AN INABILITY TO ACCESS
FINANCIAL MARKETS.

We rely upon access to both short term and longer term capital markets as a source of liquidity to satisfy our liquidity requirements. Although we believe we will maintain sufficient access to these financial markets, adverse changes in the economy, the overall health of the industries in which we operate and changes to our credit ratings could limit access to these markets and restrict the execution of our business plan.

INFLATION AND INCREASED GAS COSTS COULD ADVERSELY IMPACT OUR CUSTOMER BASE AND
CUSTOMER COLLECTIONS AND INCREASE OUR LEVEL OF INDEBTEDNESS.

Inflation has caused increases in certain operating expenses, and has required assets to be replaced at higher costs. We have a process in place to continually review the adequacy of our utility gas rates in relation to the increasing cost of providing service and the inherent regulatory lag in adjusting those gas rates. Historically, we have been able to budget and control operating expenses and investments within the amounts authorized to be collected in rates and intend to continue to do so. The ability to control expenses is an important factor that will influence future results.

The rapid increases in the price of purchased gas, which has occurred in some prior years, causes us to experience a significant increase in short-term debt because we must pay suppliers for gas when it is purchased, which can be significantly in advance of when these costs may be recovered through the collection of monthly customer bills for gas delivered. Increases in purchased gas costs also slow our utility collection efforts as customers are more likely to delay the payment of their gas bills, leading to higher than normal accounts receivable. This situation also results in higher short-term debt levels and increased bad debt expense. Should the price of purchased gas increase significantly in the upcoming heating season, we would expect increases in our short-term debt, accounts receivable and bad debt expense during fiscal 2004.

Finally, higher costs of natural gas in recent years have already caused many of our utility customers to conserve in the use of our gas services and could lead to even more customers utilizing such conservation methods.

OUR OPERATIONS ARE SUBJECT TO INCREASED COMPETITION.

We are facing increased competition from other energy suppliers as well as electric companies and from energy marketing and trading companies. In the case of industrial customers, such as manufacturing plants, and agricultural customers, adverse economic conditions, including higher gas costs, could cause these customers to use alternative sources of energy such as electricity or to bypass our systems in favor of special competitive contracts with lower per-unit costs.

HIGHLIGHTS

- On December 3, 2002, we completed the acquisition of Mississippi Valley Gas Company (MVG), a privately held utility, for approximately $150.0 million, which consisted of approximately $74.7 million in cash and 3,386,287 unregistered shares of our common stock. In addition, we paid approximately $70.9 million to repay outstanding debt of MVG. Our Mississippi Valley Gas Company Division provides natural gas distribution service to approximately 261,500 residential, industrial and other customers located primarily in the northern and central regions of Mississippi.

- In January 2003, as a result of the adoption of EITF 02-03 which precludes mark-to-market accounting for our natural gas marketing segment inventory and energy trading contracts that are not derivatives, we recorded a one-time noncash charge for a cumulative effect adjustment of $12.9 million ($7.8 million, net of income tax benefit) on the consolidated statements of income.

- On January 16, 2003, we issued $250.0 million of 5 1/8% Senior Notes due 2013. The net proceeds were used to repay debt under a short-term acquisition credit facility used to partially finance the MVG acquisition, to repay $54.0 million in unsecured senior notes held by institutional lenders, short-term debt under our commercial paper program and to provide funds for general corporate purposes.

- On June 23, 2003, we completed a public offering of 4,000,000 shares of our common stock, and we sold an additional 100,000 shares of our common stock in July 2003 when our underwriters exercised their overallotment option (collectively referred to as the 2003 Offering). The 2003 Offering was priced at $25.31 per share and generated net proceeds of approximately $99.2 million. The proceeds were used to partially fund our pension plan, to repay short-term debt and to fund general corporate purposes including the purchase of natural gas for storage.

- In June 2003, we contributed to the Atmos Energy Corporation Master Retirement Trust for the benefit of the Atmos Energy Corporation Pension Account Plan $48.6 million in cash and 1,169,700 shares of Atmos restricted common stock with a value of $28.8 million. The cash contribution was financed through a combination of cash on hand and a portion of the net proceeds received from the 2003 Offering. As a result of this contribution and improved investment returns on the assets used to fund the pension plan, the $39.4 million minimum pension liability recognized during fiscal 2002 was eliminated in fiscal 2003.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States. Preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and the related disclosures of contingent assets and liabilities. We based our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances. On an ongoing basis, we evaluate our estimates, including those related to risk management and trading activities, allowance for doubtful accounts, legal and environmental accruals, insurance accruals, pension and postretirement obligations, deferred income taxes and the valuation of goodwill, indefinite-lived intangible assets and other long-lived assets. Our critical accounting policies are reviewed by the Audit Committee on a quarterly basis. Actual results may differ from estimates.

Regulation -- Our utility operations are subject to regulation with respect to rates, service, maintenance of accounting records and various other matters by the respective regulatory authorities in the states in which we operate. Our regulated utility operations are accounted for in accordance with Statement of Financial Accounting Standards (SFAS) 71, Accounting for the Effects of Certain Types of Regulation. This statement requires cost-based, rate-regulated entities that meet certain criteria to reflect the financial effects of the ratemaking and accounting practices and policies of the various regulatory commissions in their financial statements. We record regulatory assets for costs that have been deferred for which future recovery through customer rates is considered probable. Regulatory liabilities are recorded when it is probable that revenues will be reduced for amounts that will be credited to customers through the ratemaking process. As a result, certain

27

costs that would normally be expensed under accounting principles generally accepted in the United States are permitted to be capitalized because they can be recovered through rates. Further, regulation may impact the period in which revenues or expenses are recognized. The amounts to be recovered or recognized are based upon historical experience and our understanding of the regulations. The impact of regulation on our utility operations may be affected by decisions of the regulatory authorities or the issuance of new regulations.

Revenue recognition -- Sales of natural gas to our utility customers are billed on a monthly cycle basis; however, the billing cycle periods for certain classes of customers do not necessarily coincide with accounting periods used for financial reporting purposes. We follow the revenue accrual method of accounting for utility segment revenues whereby revenues applicable to gas delivered to customers, but not yet billed under the cycle billing method, are estimated and accrued and the related costs are charged to expense.

Energy trading contracts resulting in the delivery of a commodity where we are the principal in the transaction are recorded as natural gas marketing sales or purchases at the time of physical delivery. Realized gains and losses from the settlement of financial instruments that do not result in physical delivery related to our natural gas marketing energy trading contracts and unrealized gains and losses from changes in the market value of open contracts are included as a component of natural gas marketing revenues.

Allowance for Doubtful Accounts -- For the majority of our receivables, we establish an allowance for doubtful accounts based on an aging of those receivable balances. We apply percentages to each aging category based on our collections experience. On certain other receivables where we are aware of a specific customer's inability or reluctance to pay, we record an allowance for doubtful accounts against amounts due to reduce the net receivable balance to the amount we reasonably expect to collect. However, if circumstances change, our estimate of the recoverability of accounts receivable could be different. Circumstances which could affect our estimates include, but are not limited to, customer credit issues, the level of natural gas prices and general economic conditions.

Derivatives and Hedging Activities -- We use a combination of storage and financial hedges to protect us and our natural gas utility customers against unusually large winter period gas price increases. Further, AEM manages margins and limits risk exposure on the sale of natural gas inventory or the offsetting fixed-price purchase or sale commitments for physical quantities of natural gas through the use of gas futures, including forwards, over-the-counter and exchange-traded options and swap contracts with counterparties.

Our financial hedges are accounted for under the mark-to-market method pursuant to SFAS 133, Accounting for Derivative Instruments and Hedging Activities. Changes in the valuation of assets and liabilities arising from risk management activities primarily result from changes in the valuation of the portfolio of contracts, maturity and settlement of contracts and newly originated transactions. Market prices and models used to value these transactions reflect our best estimates considering various factors including closing exchange and over-the-counter quotations, time value and volatility factors underlying the contracts. Values are adjusted to reflect the potential impact of an orderly liquidation of our positions over a reasonable period of time under present market conditions. Changes in market prices and other assumptions used in these models directly affect our estimate of the fair value of these transactions.

However, because the costs of financial instruments used in our utility segment will ultimately be recovered through our rates, current period changes in the assets and liabilities from these risk management activities are recorded as a component of deferred gas costs in accordance with SFAS 71. Accordingly, there is no earnings impact to our utility segment as a result of the use of financial instruments. The changes in the assets and liabilities from risk management activities are recognized in purchased gas cost in the income statement when the related costs are recovered through our rates.

In the management of natural gas requirements for municipalities and other local utilities, AEM sells physical natural gas to customers for future delivery. Over-the-counter swap agreements require AEM to receive or make payments based on the difference between a fixed price and the market price of natural gas on the settlement date. Options held to manage price risk provide the right, but not the obligation, to buy or sell energy commodities at a fixed price. AEM links these financial derivatives to physical delivery of natural gas

and typically balances its derivative positions at the end of each trading day. However, at any point in time, AEM may not have completely offset its risk on these activities.

AEM's physical trading activities involve utilizing physical assets (storage and transportation) to sell and deliver gas to customers or to take a position in the market based on anticipated price movement. In addition to the price risk of any net open position at the end of each trading day, the financial exposure that results from intra-day fluctuations of gas prices and the potential for daily price movements constitutes a risk of loss since the price of natural gas purchased or sold for future delivery at the beginning of the day may not be hedged until later in the day.

Impairment Assessments -- We perform impairment assessments of our goodwill, intangible assets subject to amortization and long-lived assets. We currently have no indefinite-lived intangible assets. We annually evaluate our goodwill balances for impairment during our second fiscal quarter or as impairment indicators arise. We use a present value technique based on discounted cash flows to estimate the fair value of our reporting units. Our reporting units and our operating segments are the same as each operating unit represents a component of our business. Goodwill is allocated to the reporting units responsible for the acquisition that gave rise to the goodwill.

The discounted cash flow calculations used to assess goodwill impairment are dependent on several subjective factors including the timing of future cash flows, future growth rates, and the discount rate. An impairment charge is recognized if the carrying value of a reporting unit's goodwill exceeds its fair value.

We periodically evaluate whether events or circumstances have occurred that indicate that our intangible assets subject to amortization and other long-lived assets may not be recoverable or that the remaining useful life may warrant revision. When such events or circumstances are present, we assess the recoverability of these assets by determining whether the carrying value will be recovered through expected future cash flows. These cash flow projections consider various factors such as the timing of the future cash flows and the discount rate and are based upon the best information available at the time the estimate is made. Changes in these factors could materially affect the cash flow projections and result in the recognition of an impairment charge. An impairment charge is recognized as the difference between the carrying amount and the fair value if the sum of the undiscounted cash flows is less than the carrying value of the related asset.

Pension and Other Postretirement Plans -- Pension and other postretirement plan expenses and liabilities are determined on an actuarial basis and are affected by the market value of plan assets, estimates of the expected return on plan assets and assumed discount rates and demographic data. The assumed return on plan assets is based on management's expectation of the long-term return on the portfolio of plan assets. The discount rate used to compute the present value of plan liabilities generally is based on rates of high grade corporate bonds with maturities similar to the average period over which benefits will be paid. Actual changes in the fair market value of plan assets and differences between the actual return on plan assets and the expected return on plan assets could have a material effect on the amount of pension expense ultimately recognized.

 
RESULTS OF OPERATIONS

The primary factors that impact our results of utility operations are seasonal weather patterns, competitive factors in the energy industry and economic conditions in our service areas. Natural gas sales to residential, commercial and public authority customers are affected by winter heating season requirements. This generally results in higher operating revenues and net income during the period from October through March of each year and lower operating revenues and either lower net income or net losses during the period from April through September of each year. Accordingly, our second fiscal quarter historically has been our most critical earnings quarter with an average of 68 percent of our net income having been earned in the second quarter during the three most recently completed fiscal years. Utility sales to industrial customers are much less weather sensitive. Utility sales to agricultural customers, who typically use natural gas to power irrigation pumps during the period from March through September, are primarily affected by rainfall amounts and the price of natural gas. Changes in the cost of gas impact revenue but do not directly affect our gross profit from utility operations because the fluctuations in gas prices are passed through to the customer.

Our natural gas marketing segment generates income from its industrial, utility and municipal customers through negotiated prices based on the volume of gas supplied to the customer. It also generates income by utilizing storage and transportation capacity that it controls to take advantage of the difference between near-term gas prices and prices for future delivery as well as the daily movement of gas prices.

The following table presents our financial highlights for the three fiscal years ended September 30, 2003:
