PART I
 
The terms “we,” “our,” “us,” “Atmos” and “Atmos Energy” refer to Atmos Energy Corporation and its subsidiaries, unless the context suggests otherwise.
 
ITEM 1.    Business
 
Overview
 
Atmos Energy Corporation, headquartered in Dallas, Texas, is engaged primarily in the regulated natural gas distribution and transmission and storage businesses as well as other nonregulated natural gas businesses. We are one of the country’s largest natural-gas-only distributors based on number of customers and one of the largest intrastate pipeline operators in Texas based upon miles of pipe. As of September 30, 2007, we distributed natural gas through sales and transportation arrangements to approximately 3.2 million residential, commercial, public authority and industrial customers through our six regulated natural gas distribution divisions, which covered service areas in 12 states. Our primary service areas are located in Colorado, Kansas, Kentucky, Louisiana, Mississippi, Tennessee and Texas. We have more limited service areas in Georgia, Illinois, Iowa, Missouri and Virginia. In addition, we transport natural gas for others through our distribution system.
 
Through our nonregulated businesses, we primarily provide natural gas management and marketing services to municipalities, other local gas distribution companies and industrial customers in 22 states and natural gas transportation and storage services to certain of our natural gas distribution divisions and to third parties.
 
We were organized under the laws of Texas in 1983 as Energas Company for the purpose of owning and operating the natural gas distribution business of Pioneer Corporation in Texas. In September 1988, we changed our name to Atmos Energy Corporation. As a result of the merger with United Cities Gas Company in July 1997, we also became incorporated in Virginia.
 
Operating Segments
 
Through August 31, 2007, our operations were divided into four segments:
 
  •  the utility segment , which included our regulated natural gas distribution and related sales operations,
 
  •  the natural gas marketing segment , which included a variety of nonregulated natural gas management services,
 
  •  the pipeline and storage segment , which included our regulated and nonregulated natural gas transmission and storage services and
 
  •  the other nonutility segment , which included all of our other nonregulated nonutility operations.
 
During the fourth quarter of fiscal 2007, we completed a series of organizational changes and began reporting the results of our operations under the following new segments, effective September 1, 2007:
 
  •  The natural gas distribution segment , formerly referred to as the utility segment, includes our regulated natural gas distribution and related sales operations.
 
  •  The regulated transmission and storage segment includes the regulated pipeline and storage operations of our Atmos Pipeline — Texas Division. These operations were previously included in the former pipeline and storage segment.
 
  •  The natural gas marketing segment remains unchanged and includes a variety of nonregulated natural gas management services.
 
  •  The pipeline, storage and other segment primarily is comprised of our nonregulated natural gas transmission and storage services, which were previously included in the former pipeline and storage segment.

Strategy
 
Our overall strategy is to:
 
  •  deliver superior shareholder value,
 
  •  improve the quality and consistency of earnings growth, while operating our regulated and nonregulated businesses exceptionally well and
 
  •  enhance and strengthen a culture built on our core values.
 
Over the last five fiscal years, we have primarily grown through two significant acquisitions, our acquisition in December 2002 of Mississippi Valley Gas Company (MVG) and our acquisition in October 2004 of the natural gas distribution and pipeline operations of TXU Gas Company (TXU Gas).
 
We have experienced over 20 consecutive years of increasing dividends and earnings growth after giving effect to our acquisitions. We have achieved this record of growth while efficiently managing our operating and maintenance expenses and leveraging our technology, such as our 24-hour call centers, to achieve more efficient operations. In addition, we have focused on regulatory rate proceedings to increase revenue to recover rising costs and mitigated weather-related risks through weather-normalized rates in most of our service areas. We have also strengthened our nonregulated businesses by increasing gross profit margins, expanding commercial opportunities in our regulated transmission and storage segment and actively pursuing opportunities to increase the amount of storage available to us.
 
Our core values include focusing on our employees and customers while conducting our business with honesty and integrity. We continue to strengthen our culture through ongoing communications with our employees and enhanced employee training.
 
Natural Gas Distribution Segment Overview
 
Our natural gas distribution segment consisted of the following six regulated divisions during the year ended September 30, 2007:
 
  •  Atmos Energy Mid-Tex Division,
 
  •  Atmos Energy Kentucky/Mid-States Division,
 
  •  Atmos Energy Louisiana Division,
 
  •  Atmos Energy West Texas Division,
 
  •  Atmos Energy Mississippi Division and
 
  •  Atmos Energy Colorado-Kansas Division
 
Our natural gas distribution business is a seasonal business. 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.
 
In addition to seasonality, financial results for this segment 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. Higher gas costs may also adversely impact our accounts receivable collections, resulting in higher bad debt expense and may require us to increase borrowings under our credit facilities resulting in higher interest expense.
 
The effect of weather that is above or below normal is substantially offset through weather normalization adjustments, known as WNA, which are now approved by the regulatory authorities for over 90 percent of residential and commercial meters in our service areas. WNA allows us to increase customers’ bills to offset lower gas usage when weather is warmer than normal and decrease customers’ bills to offset higher gas usage when weather is colder than normal.

  October — May

Kentucky
  November — April
Louisiana

Our supply of natural gas is provided by a variety of suppliers, including independent producers, marketers and pipeline companies and withdrawals of gas from proprietary and contracted storage assets. Additionally, the natural gas supply for our Mid-Tex Division includes peaking and spot purchase agreements.
 
Supply arrangements are contracted from our suppliers on a firm basis with various terms at market prices. The firm supply consists of both base load and swing supply (peaking) 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.
 
Currently, all of our natural gas distribution divisions, except for our Mid-Tex Division, utilize 37 pipeline transportation companies, both interstate and intrastate, to transport our natural gas. 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. The natural gas supply for our Mid-Tex Division is delivered by our Atmos Pipeline — Texas Division.
 
Except for local production purchases, we select our natural gas 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. Major suppliers during fiscal 2007 were Anadarko Energy Services, BP Energy Company, Chesapeake Energy Marketing, Inc., ConocoPhillips Company, Devon Gas Services, L.P., Enbridge Marketing (US) L.P., National Fuel Marketing Company, LLC, ONEOK Energy Services Company L.P., Tenaska Marketing and Atmos Energy Marketing, LLC, our natural gas marketing subsidiary.
 
The combination of base load, peaking and spot purchase agreements, coupled with the withdrawal of gas held in storage, allows us the flexibility to adjust to changes in weather, which minimizes our need to enter into long-term firm commitments. We estimate our peak-day availability of natural gas supply to be approximately 4.2 Bcf. The peak-day demand for our natural gas distribution operations in fiscal 2007 was on February 15, 2007, when sales to customers reached approximately 3.4 Bcf.
 
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 or applicable state statutes or regulations. Our customers’ demand on our system is not necessarily indicative of our ability to meet current or anticipated market demands or immediate delivery requirements because of factors such as the physical limitations of gathering, storage and transmission systems, the duration and severity of cold weather, the availability of gas reserves from our suppliers, the ability to purchase additional supplies on a short-term basis and actions by federal and state regulatory authorities. Curtailment rights provide us the flexibility to meet the human-needs requirements of our customers on a firm basis. Priority allocations imposed by federal and state regulatory agencies, as well as other factors beyond our control, may affect our ability to meet the demands of our customers. We anticipate no problems with obtaining additional gas supply as needed for our customers.
 
The following briefly describes our six natural gas distribution divisions. We operate in our service areas under terms of non-exclusive franchise agreements granted by the various cities and towns that we serve. At


6

September 30, 2007, we held 1,106 franchises having terms generally ranging from five to 35 years. A significant number of our franchises expire each year, which require renewal prior to the end of their terms. We believe that we will be able to renew our franchises as they expire. Additional information concerning our natural gas distribution divisions is presented under the caption “Operating Statistics”.
 
Atmos Energy Mid-Tex Division.   Our Mid-Tex Division serves approximately 550 communities in the north-central, eastern and western parts of Texas, including the Dallas/Fort Worth Metroplex. This division currently operates under one system-wide rate structure. However, the governing body of each municipality we serve has original jurisdiction over all gas distribution rates, operations and services within its city limits, except with respect to sales of natural gas for vehicle fuel and agricultural use. The Railroad Commission of Texas (RRC) 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. This division participates in Texas’ Gas Reliability Infrastructure Program (GRIP), which allows us to include in rate base annually approved capital costs incurred in the prior calendar year. The program also requires us to file a complete rate case at least once every five years.
 
Atmos Energy Kentucky/Mid-States Division.   Our Kentucky/Mid-States Division operates in more than 420 communities across Georgia, Illinois, Iowa, Kentucky, Missouri, Tennessee and Virginia. The service areas in these states are primarily rural; however, this division serves Franklin, Tennessee, which is less than 20 miles from downtown Nashville. We update our rates in this division through periodic formal rate filings made with each state’s public service commission.
 
Atmos Energy Louisiana Division.   In Louisiana, we serve nearly 300 communities, including the suburban areas of New Orleans, the metropolitan area of Monroe and western Louisiana. 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 and are recognized in our natural gas marketing segment. Our rates in this division are updated annually through a stable rate filing without filing a formal rate case.
 
Atmos Energy West Texas Division.   Our West Texas Division serves approximately 80 communities in West Texas, including the Amarillo, Lubbock and Midland areas. Like our Mid-Tex Division, each municipality we serve has original jurisdiction over all gas distribution rates, operations and services within its city limits. Similarly, the West Texas Division also participates in GRIP, which requires us to file a complete rate case at least once every five years.
 
Atmos Energy Mississippi Division.   In Mississippi, we serve about 110 communities throughout the northern half of the state, including the Jackson metropolitan area. Our rates in the Mississippi Division are updated annually through a stable rate filing without filing a formal rate case.
 
Atmos Energy Colorado-Kansas Division.   Our Colorado-Kansas Division serves approximately 170 communities throughout Colorado and Kansas and in the southwestern corner of Missouri, including Olathe, Kansas, and Greeley, Colorado. Olathe is a southern suburb of Kansas City, near the Missouri border. Greeley is located 20 miles outside of Denver. We update our rates in this division through periodic formal rate filings made with each state’s public service commission.

(3) The bad debt rider allows us to recover from ratepayers the gas cost portion of uncollectible accounts.
 
(4) The performance-based rate program provides incentives to natural gas utility companies to minimize purchased gas costs by allowing the utility company and its customers to share the purchased gas cost savings.
 
(5) The Missouri jurisdiction has a straight-fixed variable rate design which decouples gross profit margin from customer usage patterns.
