ATMOS ENERGY CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
December 31, 2016June 30, 2017
1.    Nature of Business
Atmos Energy Corporation (“Atmos Energy” or the “Company”) is engaged primarily in the regulated natural gas distribution and pipeline business.and storage businesses. Our regulated businesses are subject to federal and state regulation and/or regulation by local authorities in each of the states in which our regulated divisions and subsidiaries operate.
Our distribution business delivers natural gas through sales and transportation arrangements to approximately three million residential, commercial, public authority and industrial customers through our six natural gas distribution divisions, which at December 31, 2016,June 30, 2017, covered service areas located in eight states. In addition, we transport natural gas for others through our distribution system.
Our pipeline and storage business includes the transportation of natural gas to our North Texas and Louisiana distribution systems and the management of our underground storage facilities used to support our North Texas distribution business.businesses.
Through December 31, 2016, Atmos Energy was also engaged in certain nonregulated businesses. As more fully described in Note 6, effectiveEffective January 1, 2017, we soldcompleted the sale of all of the equity interests of Atmos Energy Marketing LLC (AEM) to CenterPoint Energy Services, Inc., a subsidiary of CenterPoint Energy, Inc. As(CES). Accordingly, AEM’s historical financial results are reflected in the Company’s condensed consolidated financial statements as discontinued operations, which required retrospective application to financial information for all periods presented. Refer to Note 6 for further information. Our discontinued natural gas marketing segment was primarily engaged in a resultnonregulated natural gas marketing business, conducted by AEM. This business provided natural gas management and transportation services to municipalities, regulated distribution companies, including certain divisions of the sale, Atmos Energy has fully exited the nonregulated gas marketing business. Additionally, as further described in Note 3, we modified our reporting segments as a result of the sale.and third parties.

2.    Unaudited Financial Information
These consolidated interim-period financial statements have been prepared in accordance with accounting principles generally accepted in the United States on the same basis as those used for the Company’s audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2016.2016, which appear in Exhibit 99.1 to our Current Report on Form 8-K dated April 12, 2017 (the "Fiscal 2016 Financial Statements"). In the opinion of management, all material adjustments (consisting of normal recurring accruals) necessary for a fair presentation have been made to the unaudited consolidated interim-period financial statements. These consolidated interim-period financial statements are condensed as permitted by the instructions to Form 10-Q and should be read in conjunction with the audited consolidated financial statements of Atmos Energy Corporation included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2016.Fiscal 2016 Financial Statements. Because of seasonal and other factors, the results of operations for the three-monthnine-month period ended December 31, 2016June 30, 2017 are not indicative of our results of operations for the full 2017 fiscal year, which ends September 30, 2017.
Except forDuring the completionthird quarter, we completed a State of Texas use tax audit that covered the saleperiod from October 2011 to March 2017, which resulted in a refund of AEM on$29.8 million. We concluded the appropriate regulatory treatment of this refund was to reduce rate base. We received $18.7 million during the third quarter, which has been included in cash flows from investing activities, and recorded an $11.1 million receivable as of June 30, 2017.
On January 3,6, 2017, our Atmos Pipeline - Texas Division filed its statement of intent seeking $63.6 million, as discussedadjusted in Note 6, noits rebuttal case, in additional annual operating income. On August 1, 2017, a final order was issued in our APT rate case resulting in a $13.0 million increase in annual operating income. No other events have occurred subsequent to the balance sheet date that would require recognition or disclosure in the condensed consolidated financial statements.

Significant accounting policies
Our accounting policies are described in Note 2 to the consolidated financial statements inof our Annual Report on Form 10-K for the fiscal year ended September 30, 2016.Fiscal 2016 Financial Statements.
As discussed in Note 3, due to the realignment of our reportable segments, prior periods' segment information has been recast in accordance with applicable accounting guidance. Additionally, as discussed in Note 6, due to the sale of AEM, prior period amounts have been presented as discontinued operations. The segment realignment and the presentation of discontinued operations dohave not impactimpacted our reported net income, financial position andor cash flows. 
During the second quarter of fiscal 2017, we completed our annual goodwill impairment assessment. Based on the assessment performed, we determined that our goodwill was not impaired.
In May 2014, the Financial Accounting Standards Board (FASB) issued a comprehensive new revenue recognition standard that will supersede virtually all existing revenue recognition guidance under generally accepted accounting principles in the United States. Under the new standard, an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies may need to use more judgment and make more estimates than under current guidance.


The new guidance will become effective for us October 1, 2018 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption.
As of December 31, 2016,June 30, 2017, we have substantially completed the evaluation of our sources of revenue and are currently assessing the effect that the new guidance will have on our financial position, results of operations, cash flows and cash flows.business processes. The conclusion of our assessment is contingent, in part, upon the completion of deliberations currently in progress by our industry, notably in connection with efforts to produce an accounting guide intended to be developed by the American Institute of Certified Public Accountants (AICPA).


In association with this undertaking, the AICPA formed a number of industry task forces, including a Power & Utilities (P&U) Task Force. Industry representatives and organizations, the largest auditing firms, the AICPA’s Revenue Recognition Working Group and its Financial Reporting Executive Committee have undertaken, and continue to undertake, consideration of several items relevant to our industry as further discussed below. Where applicable or necessary, the FASB’s Transition Resource Group (TRG) is also participating.
Currently, the industry is working to address several items including 1) the evaluation of collectability from customers if a utility has regulatory mechanisms to help assure recovery of uncollected accounts from ratepayers; 2) the accounting for funds received from third parties to partially or fully reimburse the cost of construction of an asset and 3) the accounting for alternative revenue programs, such as performance-based ratemaking. Existing alternative revenue program guidance, though excluded by the FASB in updating specific guidance associated with revenue from contracts with customers, was relocated without substantial modification to accounting guidance for rate-regulated entities. It will require separate presentation of such revenues (subject to the above-noted deliberations) in the statement of income, effective at the same time as updated guidance associated with revenue from contracts with customers becomes effective.
Currently, a timeline for the resolution of these deliberations has not been established. Additionally, we are actively working with our peers in the rate-regulated natural gas industry and with the public accounting profession to conclude on the accounting treatment for several other issues that are not expected to be addressed by the P&U Task Force. GivenBased on the uncertainty with respect to the conclusions that might arise fromprogress of these deliberations to date, we are currently unable to determinedo not believe the effectimplementation of the new guidance will have a material effect on our financial position, results of operations, cash flows or business processes orprocesses. We are currently still evaluating the transition method we will utilize to adopt the new guidance.guidance as well as the impact to our financial statement presentation and related disclosures.
In May 2015, the FASB issued guidance removing the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The guidance was effective for us on October 1, 2016, to be applied retrospectively. We measure certain pension plan assets using the net asset value per share practical expedient, which are disclosed on an annual basis in our Form 10-K. The adoption of the new standard willshould have no material impact on our results of operations, consolidated balance sheets or cash flows. 
In January 2016, the FASB issued guidance related to the classification and measurement of financial instruments. The amendments modify the accounting and presentation for certain financial liabilities and equity investments not consolidated or reported using the equity method. The guidance is effective for us beginning October 1, 2018; limited early adoption is permitted. We are currently evaluating the potential impact of this new guidance.guidance on our financial position, results of operations and cash flows.
In February 2016, the FASB issued a comprehensive new leasing standard that will require lessees to recognize a lease liability and a right-of-use asset for all leases, including operating leases, with a term greater than 12 months on its balance sheet. The new standard will be effective for us beginning on October 1, 2019; early adoption is permitted. The new leasing standard requires modified retrospective transition, which requires application of the new guidance at the beginning of the earliest comparative period presented in the year of adoption. As of June 30, 2017, we had begun the process of identifying and categorizing our lease contracts, evaluating our current business processes and identifying a lease software solution. We are currently evaluating the effect on our financial position, results of operations and cash flows.
In June 2016, the FASB issued new guidance which will require credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model. Under this model, entities will estimate credit losses over the entire contractual term of the instrument from the date of initial recognition of that instrument. In contrast, current U.S. GAAP is based on an incurred loss model that delays recognition of credit losses until it is probable the loss has been incurred. The new guidance also introduces a new impairment recognition model for available-for-sale securities that will require credit losses for available-for-sale debt securities to be recorded through an allowance account. The new standard will be effective for us beginning on October 1, 2021; early adoption is permitted beginning on October 1, 2019. We are currently evaluating the potential impact of this new guidance.guidance on our financial position, results of operations and cash flows.
In January 2017, the FASB issued new guidance that simplifies the accounting for goodwill impairments by eliminating step 2 from the goodwill impairment test. Under the new guidance, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss will be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. The new standard will be effective for our fiscal 2021 goodwill impairment test; however, early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of the new standard will have no impact on our results of operations, consolidated balance sheets or cash flows. 
In March 2017, the FASB issued new guidance related to the income statement presentation of the components of net periodic benefit cost for an entity’s sponsored defined benefit pension and other postretirement plans. The new guidance requires entities to disaggregate the current service cost component of the net benefit cost from the other components and present it with other current compensation costs for related employees in the statement of income. The other components of net


benefit cost will be presented outside of income from operations on the statement of income. In addition, only the service cost component of net benefit cost is eligible for capitalization (e.g., as part of inventory or property, plant, and equipment). The new guidance is effective for us in the fiscal year beginning on October 1, 2018 and for interim periods within that year. We are currently evaluating the potential impact of this new guidance on our financial position, results of operations and cash flows.
Regulatory assets and liabilities
Accounting principles generally accepted in the United States require cost-based, rate-regulated entities that meet certain criteria to reflect the authorized recovery of costs due to regulatory decisions in their financial statements. As a result, certain costs are permitted to be capitalized rather than expensed because they can be recovered through rates. We record certain costs as regulatory assets when 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.


Substantially all of our regulatory assets are recorded as a component of deferred charges and other assets and substantially all of our regulatory liabilities are recorded as a component of deferred credits and other liabilities. Deferred gas costs are recorded either in other current assets or liabilities and the regulatory cost of removal obligation is reported separately.

Significant regulatory assets and liabilities as of December 31, 2016June 30, 2017 and September 30, 2016 included the following:

3.    Segment Information

Through November 30, 2016, our consolidated operations were managed and reviewed through three segments:
The regulated distribution segment, which included our regulated natural gas distribution and related sales operations.
The regulated pipeline segment, which included the pipeline and storage operations of our Atmos Energy Pipeline-Texas division and,
The nonregulated segment, which included our nonregulated natural gas management, nonregulated natural gas transmission, storage and other services.

 As a result of the announced sale of Atmos Energy Marketing, we revised the information used by the chief operating decision maker to manage the Company, effective December 1, 2016. Accordingly, we will managehave been managing and reviewreviewing our consolidated operations through the following three reportable segments:
The distribution segment is primarily comprised of our regulated natural gas distribution and related sales operations in eight states and storage assets located in Kentucky and Tennessee, which are used solely to support our natural gas distribution operations in those states. These storage assets were formerly included in our nonregulated segment.
The pipeline and storage segment is comprised primarily of the pipeline and storage operations of our Atmos Pipeline-Texas division and our natural gas transmission operations in Louisiana, which were formerly included in our nonregulated segment.
The natural gas marketing segment is comprised of our discontinued natural gas marketing business.

Our determination of reportable segments considers how our chief operating decision maker allocates resources between ourthe strategic operating units under which we manage sales of various products and services through our distribution, pipeline and storage and natural gas marketing businesses.to customers in differing regulatory environments. Although our distribution segment operations are geographically dispersed,


they are aggregated and reported as a single segment as each natural gas distribution division has similar economic characteristics. In addition, because the pipeline and storage operations of our Atmos Pipeline-Texas division and our natural gas transmission operations in Louisiana have similar economic characteristics, andthey have been aggregated and reported as a single segment.

The accounting policies of the segments are the same as those described in the summary of significant accounting policies found in our Annual Report on Form 10-K for the fiscal year ended September 30, 2016.Fiscal 2016 Financial Statements. We evaluate performance based on net income or loss of the respective operating segments. We allocate interest and pension expense to the pipeline and storage segment; however, there is no debt or pension liability recorded on the pipeline and storage segment balance sheet. All material intercompany transactions have been eliminated; however, we have not eliminated intercompany profits when such amounts are probable of recovery under the affiliates’ rate regulation process.
    
Prior periods' segment information has been recast as required by applicable accounting guidance. The segment realignment doeshas not impactimpacted our reported consolidated revenues or net income. 


Income statements for the three and nine months ended December 31,June 30, 2017 and 2016 and 2015 by segment are presented in the following tables:

4.    Earnings Per Share
We use the two-class method of computing earnings per share because we have participating securities in the form of non-vested restricted stock units with a nonforfeitable right to dividend equivalents, for which vesting is predicated solely on the passage of time. The calculation of earnings per share using the two-class method excludes income attributable to these participating securities from the numerator and excludes the dilutive impact of those shares from the denominator. Basic and diluted earnings per share for the three and nine months ended December 31,June 30, 2017 and 2016 and 2015 are calculated as follows:

On June 8, 2017, we completed a public offering of $500 million of 3.00% senior notes due 2027 and $250 million of 4.125% senior notes due 2044. The effective rate of these notes is 3.12% and 4.40%, after giving effect to the offering costs and the settlement of the associated forward starting interest rate swaps. The net proceeds (excluding the loss on the settlement of the interest rate swaps of $37 million) of approximately $753 million were used to repay our $250 million 6.35% senior unsecured notes at maturity on June 15, 2017 and for general corporate purposes, including the repayment of working capital borrowings pursuant to our commercial paper program.
On September 22, 2016, we entered into a three year, $200 million multi-draw floating-rate term loan agreement with a syndicate of three lenders. Borrowings under the term loan may be made in increments of $1.0 million or higher, may be repaid at any time during the loan period and will bear interest at a rate dependent upon our credit ratings at the time of such borrowing and based, at our election, on a base rate or LIBOR for the applicable interest period. The term loan will bewas used to refinance existing indebtednessrepay short-term debt and for working capital, capital expenditures and other general corporate purposes. At December 31, 2016,June 30, 2017, there was $125.0 million outstanding under the term loan.
We utilize short-term debt to fund ongoing working capital needs, such as our seasonal requirements for gas supply, general corporate liquidity and capital expenditures. Our short-term borrowing requirements are affected primarily by the seasonal nature of the natural gas business. Changes in the price of natural gas and the amount of natural gas we need to supply our customers’ needs could significantly affect our borrowing requirements. Our short-term borrowings typically reach their highest levels in the winter months.
We currently finance our short-term borrowing requirements through a combination of a $1.5 billion commercial paper program fourand three committed revolving credit facilities and one uncommitted revolving credit facility with third-party lenders that provide approximately $1.6$1.5 billion of total working capital funding. The primary source of our funding is our commercial paper program, which is supported by a five-year unsecured $1.5 billion credit facility that expires September 25, 2021. The facility bears interest at a base rate or at a LIBOR-based rate for the applicable interest period, plus a spread ranging from zero percent to 1.25 percent, based on the Company’s credit ratings. Additionally, the facility contains a $250 million accordion feature, which provides the opportunity to increase the total committed loan to $1.75 billion. This facility was amended in October 2016 to increase the total availability from $1.25 billion. At December 31, 2016June 30, 2017 and September 30, 2016 a total of $940.7$258.6 million and $829.8 million was outstanding under our commercial paper program.



Additionally, we have a $25 million unsecured facility, which was renewed on April 1, 2017, and a $10 million unsecured revolving credit facility, which is used primarily to issue letters of credit. At December 31, 2016,June 30, 2017, there were no borrowings outstanding under either of these facilities; however, outstanding letters of credit reduced the total amount available to us under our $10 million unsecured revolving facility to $4.1 million.
The availability of funds under these credit facilities is subject to conditions specified in the respective credit agreements, all of which we currently satisfy. These conditions include our compliance with financial covenants and the continued accuracy


of representations and warranties contained in these agreements. We are required by the financial covenants in each of these facilities to maintain, at the end of each fiscal quarter, a ratio of total debt to total capitalization of no greater than 70 percent. At December 31, 2016,June 30, 2017, our total-debt-to-total-capitalization ratio, as defined in the agreements, was 5047 percent. In addition, both the interest margin and the fee that we pay on unused amounts under certain of these facilities are subject to adjustment depending upon our credit ratings.
These credit facilities and our public indentures contain usual and customary covenants for our business, including covenants substantially limiting liens, substantial asset sales and mergers. Additionally, our public debt indentures relating to our senior notes and debentures, as well as certain of our revolving credit agreements, each contain a default provision that is triggered if outstanding indebtedness arising out of any other credit agreements in amounts ranging from in excess of $15 million to in excess of $100 million becomes due by acceleration or is not paid at maturity. We were in compliance with all of our debt covenants as of December 31, 2016.June 30, 2017. If we were unable to comply with our debt covenants, we would likely be required to repay our outstanding balances on demand, provide additional collateral or take other corrective actions.
As of December 31, 2016, AEM had one uncommitted $25 million 364-day bilateral credit facility that was scheduled to expire on July 31, 2017 and one committed $15 million 364-day bilateral credit facility that was scheduled to expire on September 30, 2017. In connection with the sale of AEM discussed in Note 6, both facilities were terminated on January 3, 2017. There were no amounts outstanding under these facilities as of December 31, 2016.
6. Divestitures and Acquisitions
Divestiture of Atmos Energy Marketing (AEM)
On October 29, 2016, we entered into a Membership Interest Purchase Agreement (the Agreement) with CenterPoint Energy Services, Inc., a subsidiary of CenterPoint Energy, Inc. (CES) to sell all of the equity interests of AEM. The transaction closed on January 3, 2017, with an effective date of January 1, 2017. CES paid a cash purchase price of $38.3 million plus estimated working capital of $103.2$109.0 million for total cash consideration of $141.5$147.3 million. Of this amount, $7.0 million was placed into escrow and will be paid to the Company within 24 months of the closing date, net of any indemnification claims agreed upon between the two companies. We expect to recognizerecognized a net gain of $0.03 per diluted share on the sale in the second quarter of fiscal 2017 and completecompleted the working capital true–up during the secondthird quarter of fiscal 2017.
The operating results of our natural gas marketing reportable segment have been reported on the condensed consolidated statements of income as income from discontinued operations, net of income tax.  Accordingly, expenses related to allocable general corporate overhead and interest expense are not included in these results.  The decision to report this segment as a discontinued operation was predicated, in part, on the following qualitative and quantitative factors:  1) the disposal resultsresulted in the company becoming a fully regulated entity; 2) the fact that an entire reportable segment will bewas disposed of and 3) the fact the disposed segment represented in excess of 30 percent of consolidated revenues over the last five fiscal years.
The tables below set forth selected financial and operational information related to assets, liabilities and operating results related to discontinued operations. Operating expenses include operation and maintenance expense, provision for doubtful accounts, depreciation and amortization expense and taxes, other than income. Additionally, assets and liabilities related to our natural gas marketing operations are classified as “held for sale” in other current assets and liabilities in our condensed consolidated balance sheets at December 31, 2016 and in other current assets, deferred charges and other assets, other current liabilities and deferred credits and other liabilities inon our consolidated balance sheetssheet at September 30, 2016. Prior period revenues and expenses associated with these assets have been reclassified into discontinued operations. This reclassification had no impact on previously reported consolidated net income.

Acquisition of EnLink Pipeline
On December 20, 2016, we executed a purchase and sale agreement to acquire the general partnership and limited partnership interests in EnLink North Texas Pipeline, LP (EnLink Pipeline) from EnLink Energy GP, LLC and EnLink Midstream Operating, LP for an all–a cash purchase price of $85 million, plus estimated working capital. After considering estimated working capital the total proceeds paid were $85.7of $1.1 million. The final purchase is subject to adjustment after the estimated working capital is finalized during the second quarter of fiscal 2017.

EnLink Pipeline's primary asset iswas a 140–mile natural gas pipeline located on the north side of the Dallas–Fort Worth Metroplex. As of December 31, 2016, theThe $85 million purchase price was preliminarilyhas been allocated, based on fair value using observable market inputs, to the net book value of the acquired pipeline. The final purchase price allocation is subject to adjustment pending the completion of analysis of the fair value of certain contracts included in the acquisition. We expect to complete this evaluation during the second quarter of fiscal 2017.



7.    Shareholders' Equity

Shelf Registration and At-the-Market Equity Sales Program
On March 28, 2016, we filed a registration statement with the Securities and Exchange Commission (SEC) that originally permitted us to issue, from time to time, up to $2.5 billion in common stock and/or debt securities. We also filed a prospectus supplement under the registration statement relating to an at-the-market (ATM) equity distribution program under which we may issue and sell, shares of our common stock, up to an aggregate offering price of $200 million. During the first fiscal quarter ofnine months ended June 30, 2017, we sold 690,8121,303,494 shares of common stock under our existing ATM program for $50.0$100 million and received net proceeds of $49.4$98.8 million. At December 31, 2016,June 30, 2017, approximately $2.4$1.6 billion of securities remainremained available for issuance under the shelf registration statement and approximately $50 million of equity remained available for issuancesubstantially all shares have been issued under theour ATM program.

Accumulated Other Comprehensive Income (Loss)
We record deferred gains (losses) in AOCI related to available-for-sale securities, interest rate cash flow hedges and commodity contract cash flow hedges. Deferred gains (losses) for our available-for-sale securities and commodity contract cash flow hedges are recognized in earnings upon settlement, while deferred gains (losses) related to our interest rate agreement cash flow hedges are recognized in earnings as they are amortized. The following tables provide the components of our accumulated other comprehensive income (loss) balances, net of the related tax effects allocated to each component of other comprehensive income (loss).:

The assumptions used to develop our net periodic pension cost for the three and nine months ended December 31,June 30, 2017 and 2016 and 2015 are as follows:
 Pension Benefits Other Benefits Pension Benefits Other Benefits
 2016 2015 2016 2015 2017 2016 2017 2016
Discount rate 3.73% 4.55% 3.73% 4.55% 3.73% 4.55% 3.73% 4.55%
Rate of compensation increase 3.50% 3.50% N/A N/A 3.50% 3.50% N/A N/A
Expected return on plan assets 7.00% 7.00% 4.45% 4.45% 7.00% 7.00% 4.45% 4.45%
The discount rate used to compute the present value of a plan’s liabilities generally is based on rates of high-grade corporate bonds with maturities similar to the average period over which the benefits will be paid. Generally, our funding policy has been to contribute annually an amount in accordance with the requirements of the Employee Retirement Income Security Act of 1974. In accordance with the Pension Protection Act of 2006 (PPA), we determined the funded status of our plan as of January 1, 2016.2017. Based on that determination, we wereare not required to make a minimum contribution to our defined benefit plan during fiscal 2017; however, we made a voluntary contribution of $5.0 million during the firstthird quarter of fiscal 2017.
We contributed $3.0$9.9 million to our other post-retirement benefit plans during the threenine months ended December 31, 2016.June 30, 2017. We expect to contribute a total of between $10 million and $20 million to these plans during fiscal 2017.

9.    Commitments and Contingencies
Litigation and Environmental Matters
With respect to the specific litigation and environmental-related matters or claims that were disclosed in Note 11 to the financial statements inof our Annual Report on Form 10-K for the fiscal year ended September 30,Fiscal 2016 Financial Statements, there were no material changes in the status of such litigation and environmental-related matters or claims during the threenine months ended December 31, 2016.June 30, 2017.
We are a party to various litigation and environmental-related matters or claims that have arisen in the ordinary course of our business. While the results of such litigation and response actions to such environmental-related matters or claims cannot be predicted with certainty, we continue to believe the final outcome of such litigation and matters or claims will not have a material adverse effect on our financial condition, results of operations or cash flows.
Purchase Commitments
Our natural gas distribution divisions except for our Mid-Tex Division, maintain supply contracts with several vendors that generally cover a period of up to one year. Commitments for estimated base gas volumes are established under these


contracts on a monthly basis at contractually negotiated prices. Commitments for incremental daily purchases are made as necessary during the month in accordance with the terms of the individual contract.
Our Mid-Tex Division also maintains a limited number of long-term supply contracts to ensure a reliable source of gas for our customers in its service area, which obligate it to purchase specified volumes at prices indexed to natural gas distribution hubs. TheseAt June 30, 2017, we were committed to purchase commitment contracts are detailed in our Annual Report on Form 10-K for the fiscal53.2 Bcf within one year, ended September 30, 2016. There were no material changes37.6 Bcf within two to the purchase commitments for the three months ended December 31, 2016.years and 0.4 Bcf beyond three years under indexed contracts.
Regulatory Matters
Various regulatory agencies, including the SEC and the Commodities Futures Trading Commission, continue to adopt regulations implementing many of the provisions of the Dodd-Frank Act of 2010. We continue to enact new procedures and modify existing business practices and contractual arrangements to comply with such regulations.  Additional rulemakings are pending which we believe will result in new reporting and disclosure obligations. The costs associated with hedging certain risks inherent in our business may be further increased when these expected additional regulations are adopted.
As of December 31, 2016,June 30, 2017, formula rate mechanisms were in progresspending regulatory approval in our Louisiana Tennessee, Mississippi and West Texas service areas,area, infrastructure mechanisms were in progresspending regulatory approval in our Mississippi Colorado and KansasVirginia service areas and an ad valorem tax rider filing was in progressrate cases were pending regulatory approval in our KansasColorado service area.area and Texas service area related to APT. These regulatory proceedings are discussed in further detail below in Management’s Discussion and Analysis — Recent Ratemaking Developments.
10.    Financial Instruments
We currently use financial instruments to mitigate commodity price risk and interest rate risk. The objectives and strategies for using financial instruments and the related accounting for these financial instruments are fully described in Notes 2 and 13 toof our Fiscal 2016 Financial Statements. During the consolidated financial statements in our Annual Report on Form 10-Knine months ended June 30, 2017, except for the fiscal year ended September 30, 2016. Duringchange in the three months ended December 31, 2016scope of our natural gas marketing commodity risk management activities as a result of the sale of AEM, there were no material


changes in our objectives, strategies and accounting for using financial instruments. Our financial instruments do not contain any credit-risk-related or other contingent features that could cause payments to be accelerated when our financial instruments are in net liability positions. The following summarizes those objectives and strategies.

Regulated Commodity Risk Management Activities
Our purchased gas cost adjustment mechanisms essentially insulate our distribution segment from commodity price risk; however, our customers are exposed to the effects of volatile natural gas prices. We manage this exposure through a combination of physical storage, fixed-price forward contracts and financial instruments, primarily over-the-counter swap and option contracts, in an effort to minimize the impact of natural gas price volatility on our customers during the winter heating season.
We typically seek to hedge between 25 and 50 percent of anticipated heating season gas purchases using financial instruments. For the 2016-2017 heating season (generally October through March), in the jurisdictions where we are permitted to utilize financial instruments, we anticipate hedginghedged approximately 27 percent, or 16.2 Bcf of the winter flowing gas requirements. We have not designated these financial instruments as hedges for accounting purposes.

Natural Gas Marketing Commodity Risk Management Activities
Our natural gas marketing segment was exposed to risks associated with changes in the market price of natural gas through the purchase, sale and delivery of natural gas to its customers at competitive prices. Through December 31, 2016, we managed our exposure to such risks through a combination of physical storage and financial instruments, including futures, over-the-counter and exchange-traded options and swap contracts with counterparties. These financial instruments have maturity dates ranging from one to 60 months. Effective January 1, 2017, as a result of the sale of AEM, these activities will bewere discontinued.
Due to the anticipated sale of AEM, we determined that the cash flows associated with our natural gas marketing commodity cash flow hedges were no longer probable of occurring; therefore, we discontinued hedge accounting as of December 31, 2016. As a result, we reclassified the gain in accumulated other comprehensive income associated with the commodity contracts into earnings as a reduction of purchased gas costscost and recognized a pre-tax gain of $10.6 million, for the three months ended December 31, 2016, which is included in income from discontinued operations on the condensed consolidated statement of income.




income for the three months ended December 31, 2016.

Interest Rate Risk Management Activities
We periodically manage interest rate risk by entering into financial instruments to effectively fix the Treasury yield component of the interest cost associated with anticipated financings.
As of December 31, 2016,June 30, 2017, we had forward starting interest rate swaps to effectively fix the Treasury yield component associated with the anticipated issuance of $250 million and $450 million unsecured senior notes in fiscal 2017 and fiscal 2019 at 3.37% and 3.78%, which we designated as a cash flow hedgeshedge at the time the swaps were executed. As of December 31, 2016,June 30, 2017, we had $18.2$41.5 million of net realized losses in accumulated other comprehensive income (AOCI) associated with the settlement of financial instruments used to fix the Treasury yield component of the interest cost of financing various issuances of long-term debt and senior notes, which will be recognized as a component of interest expense over the life of the associated notes from the date of settlement. The remaining amortization periods for these settled amounts extend through fiscal 2045.
 
Quantitative Disclosures Related to Financial Instruments
The following tables present detailed information concerning the impact of financial instruments on our condensed consolidated balance sheet and income statements.
As of December 31, 2016,June 30, 2017, our financial instruments were comprised of both long and short commodity positions. A long position is a contract to purchase the commodity, while a short position is a contract to sell the commodity. As of December 31, 2016,June 30, 2017, we had 18,833 MMcf of net long/(short)short commodity contracts outstanding in the following quantities:

Impact of Financial Instruments on the Income Statement
Hedge ineffectiveness for our natural gas marketing segment iswas recorded as a component of purchased gas cost, which is included in discontinued operations on the condensed consolidated statements of income, and primarily results from differences in the location and timing of the derivative instrument and the hedged item. Hedge ineffectiveness could materially affect our results of operations for the reported period. For the three months ended December 31,June 30, 2016, we recognized a gain arising from fair value and 2015,cash flow hedge ineffectiveness of $13.6 million. For the nine months ended June 30, 2017 and 2016, we recognized gains arising from fair value and cash flow hedge ineffectiveness of $3.4 million and $7.9$18.1 million. Additional information regarding ineffectiveness recognized in the income statement is included in the tables below.

Basis ineffectiveness arises from natural gas market price differences between the locations of the hedged inventory and the delivery location specified in the hedge instruments. Timing ineffectiveness arises due to changes in the difference between the spot price and the futures price, as well as the difference between the timing of the settlement of the futures and the valuation of the underlying physical commodity. As the commodity contract nears the settlement date, spot-to-forward price differences should converge, which should reduce or eliminate the impact of this ineffectiveness on purchased gas cost. To the extent that the Company’s natural gas inventory does not qualify as a hedged item in a fair-value hedge, or has not been designated as such, the natural gas inventory is valued at the lower of cost or market.

Cash Flow Hedges

Financial Instruments Not Designated as Hedges
The impact of the natural gas marketing segmentsegment's financial instruments that havehad not been designated as hedges on our condensed consolidated income statements for the three months ended December 31,June 30, 2016 and 2015 was a decrease (increase) in purchased gas cost of $6.8 million and $(2.2)$1.9 million, which is included in discontinued operations on the condensed consolidated statements of income. For the nine months ended June 30, 2017 and 2016 purchased gas cost (increased) decreased by $6.8 million and $(2.8) million.
As discussed above, financial instruments used in our distribution segment are not designated as hedges. However, there is no earnings impact on our distribution segment as a result of the use of these financial instruments because the gains and losses arising from the use of these financial instruments are recognized in the consolidated statement of income as a component of purchased gas cost when the related costs are recovered through our rates and recognized in revenue. Accordingly, the impact of these financial instruments is excluded from this presentation.
11.    Fair Value Measurements
We report certain assets and liabilities at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). We record cash and cash equivalents, accounts receivable and accounts payable at carrying value, which substantially approximates fair value due to the short-term nature of these assets and liabilities. For other financial assets and liabilities, we primarily use quoted market prices and other observable market pricing information to minimize the use of unobservable pricing inputs in our measurements when determining fair value. The methods used to determine fair value for our assets and liabilities are fully


described in Note 2 to the financial statements inof our Annual Report on Form 10-K for the fiscal year ended September 30, 2016.Fiscal 2016 Financial Statements. During the threenine months ended December 31, 2016,June 30, 2017, there were no changes in these methods.
Fair value measurements also apply to the valuation of our pension and postretirement plan assets. Current accounting guidance requires employers to annually disclose information about fair value measurements of the assets of a defined benefit pension or other postretirement plan. The fair value of these assets is presented in Note 7 to the financial statements inof our Annual Report on Form 10-K for the fiscal year ending September 30, 2016.Fiscal 2016 Financial Statements.
Quantitative Disclosures
Financial Instruments
The classification of our fair value measurements requires judgment regarding the degree to which market data is observable or corroborated by observable market data. Authoritative accounting literature establishes a fair value hierarchy that prioritizes the inputs used to measure fair value based on observable and unobservable data. The hierarchy categorizes the inputs into three levels, with the highest priority given to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1), with the lowest priority given to unobservable inputs (Level 3). The following tables summarize, by level within the fair value hierarchy, our assets and liabilities that were accounted for at fair value on a recurring basis as of December 31, 2016June 30, 2017 and September 30, 2016. Assets and liabilities are categorized in their entirety based on the lowest level of input that is significant to the fair value measurement.

These securities are reported at market value with unrealized gains and losses shown as a component of accumulated other comprehensive income (loss). We regularly evaluate the performance of these investments on a fund by fund basis for impairment, taking into consideration the fund’s purpose, volatility and current returns. If a determination is made that a decline in fair value is other than temporary, the related fund is written down to its estimated fair value and the other-than-temporary impairment is recognized in the income statement.
Other Fair Value Measures
Our debt is recorded at carrying value. The fair value of our debt is determined using third party market value quotations, which are considered Level 1 fair value measurements for debt instruments with a recent, observable trade or Level 2 fair value measurements for debt instruments where fair value is determined using the most recent available quoted market price.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Board of Directors and Shareholders of
Atmos Energy Corporation
We have reviewed the condensed consolidated balance sheet of Atmos Energy Corporation and subsidiaries as of December 31, 2016June 30, 2017 and the related condensed consolidated statements of income and comprehensive income for the three and nine-month periods ended June 30, 2017 and 2016 and the condensed consolidated statements of cash flows for the three-monthnine-month periods ended December 31, 2016June 30, 2017 and 2015.2016. These financial statements are the responsibility of the Company’s management.
We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.
Based on our review, we are not aware of any material modifications that should be made to the condensed consolidated financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.
We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Atmos Energy Corporation and subsidiaries as of September 30, 2016, and the related consolidated statements of income, comprehensive income, shareholders’ equity, and cash flows for the year then ended, not presented herein, and in our report dated November 14, 2016 except for the effects of the change in segments described in Note 3 and the discontinued operations described in Note 15, to which the date is April 12, 2017, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of September 30, 2016, is fairly stated, in all material respects, in relation to the consolidated balance sheets from which it has been derived.

Item 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations
INTRODUCTION
The following discussion should be read in conjunction with the condensed consolidated financial statements in this Quarterly Report on Form 10-Q and Management’s Discussion and Analysis, which appears in Item 7 of Exhibit 99.1 to our AnnualCurrent Report on Form 10-K for the year ended September 30, 2016.8-K dated April 12, 2017.
Cautionary Statement for the Purposes of the Safe Harbor under the Private Securities Litigation Reform Act of 1995
The statements contained in this Quarterly Report on Form 10-Q may contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and 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 us 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 our documents or oral presentations, the words “anticipate”, “believe”, “estimate”, “expect”, “forecast”, “goal”, “intend”, “objective”, “plan”, “projection”, “seek”, “strategy” 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 our strategy, operations, markets, services, rates, recovery of costs, availability of gas supply and other factors. These risks and uncertainties include the following: our ability to continue to access the credit and capital markets to satisfy our liquidity requirements; regulatory trends and decisions, including the impact of rate proceedings before various state regulatory commissions; the impact of adverse economic conditions on our customers; the effects of inflation and changes in the availability and price of natural gas; the availability and accessibility of contracted gas supplies, interstate pipeline and/or storage services; market risks beyond our control affecting our risk management activities, including commodity price volatility, counterparty creditworthiness or performance and interest rate risk; the concentration of our distribution, pipeline and storage operations in Texas; increased competition from energy suppliers and alternative forms of energy; adverse weather conditions; the capital-intensive nature of our natural gas distribution, business;pipeline and storage businesses; increased costs of providing health care benefits, along with pension and postretirement health care benefits and increased funding requirements; the inability to continue to hire, train and retain appropriate personnel; possible increased federal, state and local regulation of the safety of our operations; increased federal regulatory oversight and potential penalties; the impact of environmental regulations on our business; the impact of climate changes or related additional legislation or regulation in the future; the inherent hazards and risks involved in operating our distribution and pipeline and storage businesses; the threat of cyber-attacks or acts of cyber-terrorism that could disrupt our business operations and information technology systems; natural disasters, terrorist activities or other events and other risks and uncertainties discussed herein, all of which are difficult to predict and many of which are beyond our control. Accordingly, while we believe 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, we undertake no obligation to update or revise any of our forward-looking statements whether as a result of new information, future events or otherwise.
OVERVIEW
Atmos Energy and our subsidiaries are engaged primarily in the regulated natural gas distribution and transmission and storage businesses, as well as our natural gas marketing business through December 31, 2016. We distribute natural gas through sales and transportation arrangements to approximately three million residential, commercial, public authority and industrial customers throughout our six natural gas distribution divisions, which at December 31, 2016June 30, 2017 covered service areas located in eight states. In addition, we transport natural gas for others through our distribution and pipeline systems.
Through December 31, 2016, our natural gas marketing businesses, we havebusiness provided natural gas management and marketing services to municipalities, other local gas distribution companies and industrial customers primarily in the Midwest and Southeast. We completed the sale of this business in January 2017.

As discussed in Note 3, beginning with the quarter ended December 31, 2016, we willWe manage and review our consolidated operations through the following three reportable segments:
The distribution segment is primarily comprised of our regulated natural gas distribution and related sales operations in eight states, and storage assets located in Kentucky and Tennessee, which are used to support our natural gas distribution operations in those states. These storage assets were formerly included in our nonregulated segment.
The pipeline and storage segment, is comprised primarily of the pipeline and storage operations of our Atmos Energy Pipeline-Texas division and our natural gas transmission operations in Louisiana, which were formerly included in our former nonregulated segment..segment.
The natural gas marketing segment, is comprised of our discontinued natural gas marketing business.





CRITICAL ACCOUNTING ESTIMATES AND POLICIES
Our condensed 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, the 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. Actual results may differ from such estimates.
Our critical accounting policies used in the preparation of our consolidated financial statements are described in Item 7 of Exhibit 99.1 to our AnnualCurrent Report on Form 10-K for the fiscal year ended September 30, 20168-K dated April 12, 2017 and include the following:

Regulation
Unbilled revenue
Pension and other postretirement plans
Contingencies
Financial instruments and hedging activities
Fair value measurements
Impairment assessments

Our critical accounting policies are reviewed periodically by the Audit Committee of our Board of Directors. There were no significant changes to these critical accounting policies during the threenine months ended December 31, 2016.June 30, 2017.

Non-GAAP Financial Measure
Our operations are affected by the cost of natural gas. The cost of gas is passed through to our customers without markup and includes commodity price, transportation, storage, injection and withdrawal fees and settlements of financial instruments used to mitigate commodity price risk. These costs are reflected in the income statement as purchased gas cost. Therefore, increases in the cost of gas are offset by a corresponding increase in revenues. Accordingly, we believe Gross Profit, a non-GAAP financial measure defined as operating revenues less purchased gas cost, is a better indicator of our financial performance than operating revenues as it provides a useful and more relevant measure to analyze our financial performance. As such, the following discussion and analysis of our financial performance will reference gross profit rather than operating revenues and purchased gas cost individually.

RESULTS OF OPERATIONS

Executive Summary
Atmos Energy strives to operate its businesses safely and reliably while delivering superior shareholder value. In recent years, we have implemented rate designs that reduce or eliminate regulatory lag and separate the recovery of our approved rate from customer usage patterns. Additionally, we have significantly increased investments in the safety and reliability of our natural gas distribution and transmission infrastructure. This increased level of investment and timely recovery of these investments through our regulatory mechanisms has resulted in increased earnings and operating cash flows in recent years.
The pursuit of our strategy was the primary driver for our decision to sell our nonregulated natural gas marketing business and to fully exit that business. The sale was announced in October 2016 and closed in January 2017 with the receipt of $134.5$140.3 million in cash proceeds, including estimated working capital. We expect to recordrecorded a net gain of $0.03 per diluted share on the sale in the second quarter of fiscal 2017. The proceeds received from the transaction will bewere used to fund infrastructure additions and enhancements in our remaining businesses. As a result of the sale, the results of operations for the divested business have been presented as discontinued operations.operations in the tables below:

Net income from continuing operations increased 12.312 percent, quarter-over-quartercompared to the prior-year period, despite weather that was 30 percent warmer than normal and 12 percent warmer than the prior-year period, primarily due to positive rate outcomes and customer growth in our distribution business. During the first quarter of fiscalnine months ended June 30, 2017, our distribution segment had completed three17 regulatory proceedings, resulting in an increase in annual operating income of $4.6$85.0 million and had ninefour ratemaking efforts in progress at December 31, 2016June 30, 2017 seeking $28.9$17.1 million of additional annual operating income. Additionally, on January 6, 2017, our Atmos Pipeline - Texas Division filed its statement of intent seeking $55.2$63.6 million, as adjusted in its rebuttal case, in additional annual operating income. On August 1, 2017, a final order was issued resulting in a $13 million increase in annual operating income. Our discontinued natural gas marketing results improved quarter-over-quarterfor the nine months ended June 30, 2017 primarily due toinclude a pre-tax gain of $10.6 million recognized in the currentfirst fiscal quarter related to the discontinuance of cash flow hedging for our natural gas marketing commodity contracts.contracts and a $2.7 million net gain on sale recognized in January 2017 upon completion of the sale.
Capital expenditures for the first threenine months of fiscal 2017 were $298.0$812.1 million. Approximately 7882 percent was invested to improve the safety and reliability of our distribution and transportation systems, with a significant portion of this investment incurred under regulatory mechanisms that reduce lag to six months or less. We expect our capital expenditures to range between $1.1 billion and $1.25 billion for fiscal 2017. We funded our capital expenditure program primarily through operating cash flows of $117.0$745.6 million. Additionally, we issued approximately $885 million $125of long-term debt and $100 million in borrowings under our three-year $200 million multi-draw term loan, $49.4 million in proceeds from the issuance of common stock underduring the nine month period ending June 30, 2017. The net proceeds from these issuances was primarily used to repay maturing long-term debt and to reduce short-term debt.
In addition, we acquired EnLink Pipeline in the first fiscal quarter of 2017 for an all–cash price of $86.1 million, inclusive of working capital. The acquisition of EnLink Pipeline increases the capacity on our at-the-market equity distribution program and net short-term debt borrowings.APT intrastate pipeline to serve transportation customers in North Texas, which continues to experience significant population growth.
As a result of our sustained financial performance, cash flows and capital structure, our Board of Directors increased the quarterly dividend by 7.1 percent for fiscal 2017.


Distribution Segment
The distribution segment is primarily comprised of our regulated natural gas distribution and related sales operations in eight states, and storage assets located in Kentucky and Tennessee, which are used to support our regulated natural gas distribution operations in those states. These storage assets were previously included in our former nonregulated segment. The primary factors that impact the results of this segment are our ability to earn our authorized rates of return, the cost of natural gas, competitive factors in the energy industry and economic conditions in our service areas.
Our ability to earn our authorized rates of return is based primarily on our ability to improve the rate design in our various ratemaking jurisdictions by reducing or eliminating regulatory lag and, ultimately, separating the recovery of our approved margins from customer usage patterns. Improving rate design is a long-term process and is further complicated by the fact that we operate in multiple rate jurisdictions.
Seasonal weather patterns can also affect our distribution operations. However, the effect of weather that is above or below normal is substantially offset through weather normalization adjustments, known as WNA, which has been approved by state regulatory commissions for approximately 97 percent of our residential and commercial meters in the following states for the following time periods:
  
Kansas, West TexasOctober — May
TennesseeOctober — April
Kentucky, Mississippi, Mid-TexNovember — April
LouisianaDecember — March
VirginiaJanuary — December
Our distribution operations are also affected by the cost of natural gas. The cost of gas is passed through to our customers without markup. Therefore, increases in the cost of gas are offset by a corresponding increase in revenues. Accordingly, we believe gross profit is a better indicator of our financial performance than revenues. However, grossGross profit in our Texas and Mississippi service areas includes franchise fees and gross receipts taxes, which are calculated as a percentage of revenue (inclusive of gas costs). Therefore, the amount of these taxes included in revenues is influenced by the cost of gas and the level of gas sales volumes. We record the associated tax expense as a component of taxes, other than income. Although changes in these revenue-related taxes arising from changes in gas costs affect gross profit, over time the impact is offset within operating income.
As discussed above, the cost of gas typically does not have a direct impact on our gross profit. However, higher gas costs mean higher bills for our customers, which may 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. In addition, higher gas costs, as well as competitive factors in the industry and general economic conditions may cause customers to conserve or, in the case of industrial consumers, to use alternative energy sources. However, gas cost risk has been mitigated in recent years through improvements in rate design that allow us to collect from our customers the gas cost portion of our bad debt expense on approximately 75 percent of our residential and commercial margins.

Income for our distribution segment increased 1520 percent, primarily due to a $23.9$19.0 million increase in gross profit, partially offset with a $9.1$5.6 million increase in operating expenses. The quarter-over-quarter increase in gross profit primarily reflects:
a $15.9$13.7 million net increase in rate adjustments, primarily in our Mid-Tex, West Texas, Louisiana and West TexasMississippi Divisions.
a $2.6 million increase in revenue-related taxes in our Mid-Tex and West Texas Divisions, offset by a corresponding $2.2 million increase in the related tax expense.
Customer growth, primarily in our Mid-Tex Louisiana and Tennessee service areas,Division, which contributed an incremental $1.7$1.1 million.
a $1.8 million net increase in residential and commercial consumption, primarily in our Mid-Tex Division.
The increase in operating expenses, which includeincludes operation and maintenance expense, provision for doubtful accounts, depreciation and amortization expense and taxes, other than income, was primarily due to higher levels of pipeline maintenance and higher depreciation and property tax expense associated with increased capital investments.
Additionally, interest expense increased $0.7 million due toinvestments, as well as higher average short-term debt balances and interest rates and expense associated with $125.0 million of incremental debt financing issued during the first quarter of fiscal 2017.administrative expenses.

Annual Formula Rate Mechanisms
As an instrument to reduce regulatory lag, formula rate mechanisms allow us to refresh our rates on an annual basis without filing a formal rate case. However, these filings still involve discovery by the appropriate regulatory authorities prior to the final determination of rates under these mechanisms. We currently have formula rate mechanisms in our Louisiana, Mississippi and Tennessee operations and in substantially all of our Texas divisions. Additionally, we have specific infrastructure programs in substantially all of our distribution divisions with tariffs in place to permit the investment associated with these programs to have their surcharge rate adjusted annually to recover approved capital costs incurred in a prior test-year


period. The following table summarizes our annual formula rate mechanisms by state.state:

(2)The Trans Louisiana RSC rates were implemented subject to refund on April 1, 2017.
Rate Case Filings
A rate case is a formal request from Atmos Energy to a regulatory authority to increase rates that are charged to our customers. Rate cases may also be initiated when the regulatory authorities request us to justify our rates. This process is referred to as a “show cause” action. Adequate rates are intended to provide for recovery of the Company’s costs as well as a fair rate of return and ensure that we continue to deliver reliable, reasonably priced natural gas service safely to our customers.

Pipeline and Storage Segment
Our pipeline and storage segment consists of the pipeline and storage operations of our Atmos Pipeline–Texas Division (APT) and our natural gas transmission operations in Louisiana, which were previously included in our former nonregulated segment. APT is one of the largest intrastate pipeline operations in Texas with a heavy concentration in the established natural gas producing areas of central, northern, eastern and easternwestern Texas, extending into or near the major producing areas of the Barnett Shale, the Texas Gulf Coast and the Delaware and Val VerdeMidland Basins of West Texas. APT provides transportation and storage services to our Mid-Tex Division, other third-party local distribution companies, industrial and electric generation customers, as well as marketers and producers. As part of its pipeline operations, APT manages five underground storage reservoirsfacilities in Texas.
Our natural gas transmission operations in Louisiana are comprised of a proprietary 21-mile pipeline located in New Orleans, Louisiana that is primarily used to aggregate gas supply for our distribution division in Louisiana under a long-term contract and on a more limited basis, to third parties. The demand fee charged to our Louisiana distribution division for these services is subject to regulatory approval by the Louisiana Public Service Commission. TheyWe also manage two asset management plans with distribution affiliates of the Company which have been approved by applicable state regulatory commissions. Generally, these asset management plans require us to share with our distribution customers a significant portion of the cost savings earned from these arrangements.
Our pipeline and storage segment is impacted by seasonal weather patterns, competitive factors in the energy industry and economic conditions in our Mid-TexTexas and Louisiana service areas. Natural gas prices do not directly impact the results of this segment as revenues are derived from the transportation and storage of natural gas. However, natural gas prices and demand for natural gas could influence the level of drilling activity in the markets that we serve, which may influence the level of throughput we may be able to transport on our pipeline. Further, natural gas price differences between the various hubs that we serve in Texas could influence the volumes of gas transported for shippers through our Texas pipeline system and the rates for such transportation.
The results of APT are also significantly impacted by the natural gas requirements of the Mid–Tex Division because it is the primary transporter of natural gas for our Mid–Tex Division.its local distribution company customers. Additionally, its operations may be impacted by the timing of when costs and expenses are incurred and when these costs and expenses are recovered through its tariffs.
APT annually uses GRIP to recover capital costs incurred in the prior calendar year. However, GRIP also requires a utility to file a statement of intent at least once every five years to review its costs and expenses, including capital costs filed for recovery under GRIP. On January 6, 2017, APT filed its statement of intent seeking $55.2 million in additional annual operating income. APT customarily submits an annual GRIP filing during the second fiscal quarter of each fiscal year. However, APT is precluded from submitting a GRIP filing until a final order has been issued on the


statement of intent. Accordingly, APT willhas not be submittingyet submitted its annual GRIP filing during the second quarterfor calendar year 2016. On January 6, 2017, APT filed its statement of fiscal 2017. The Railroad Commission of Texas has 185 days to issueintent seeking $63.6 million, as adjusted in its rebuttal case, in additional annual operating income. On August 1, 2017, a final order was issued resulting in this proceeding.a $13 million increase in annual operating income.
On December 21, 2016, the Louisiana Public Service Commission approved an annual increase of five percent to the demand fee charged by our natural gas transmission pipeline for each of the next 10 years, effective October 1, 2017. This agreement will replace the existing agreement that will expireexpires in September 2017.

Net income for our pipeline and storage segment decreased four percent, primarily due to a $2.9 million increase in operating expenses, offset by a $1.7 million increase in gross profit. The increase in gross profit is primarily the result of higher through system revenue of $1.3 million, largely related to incremental throughput on the EnLink Pipeline, which was acquired in the first quarter of fiscal 2017, and higher basis spreads due to increased production in the Permian Basin. As noted above, as a result of the annual rate case, we did not file our annual GRIP filing during the second quarter of fiscal 2017, which influenced this segment's performance quarter-over-quarter.
Operating expenses, which includes operation and maintenance expense, provision for doubtful accounts, depreciation and amortization expense and taxes, other than income, increased $2.9 million, primarily due to higher depreciation expense and property taxes associated with increased capital investments and the acquisition of EnLink Pipeline.

Net income for our pipeline and storage segment increased fourthree percent, primarily due to a $10.6$22.4 million increase in gross profit, offset by an $8.2a $16.0 million increase in operating expenses. The increase in gross profit primarily reflects a $10.8$22.1 million increase in rates from the GRIP filings approved in fiscal 2016.
Operating expenses, which includes operation and maintenance expense, provision for doubtful accounts, depreciation and amortization expense and taxes, other than income, increased $8.2$16.0 million, primarily due to increased levels of pipeline maintenance and integrity activities and higher depreciation expense and property taxes associated with increased capital investments.
Additionally, interest expense increased $0.8 million due to higher average short-term debt balancesinvestments and interest rates and expense associated with $125.0 millionthe acquisition of incremental debt financing issued during the first quarter of fiscal 2017.



EnLink Pipeline.
Natural Gas Marketing Segment
Through December 31, 2016, we were engaged in an unregulated natural gas marketing business, which was conducted by Atmos Energy Marketing (AEM). AEM’s primary business iswas to aggregate and purchase gas supply, arrange transportation and storage logistics and ultimately deliver gas to customers at competitive prices. Additionally, AEM utilizesutilized proprietary and customer–owned transportation and storage assets to provide various services its customers request.requested. AEM servesserved most of its customers under contracts generally having one to two year terms. As a result, AEM’s margins arisearose from the types of commercial transactions it hashad structured with its customers and its ability to identify the lowest cost alternative among the natural gas supplies, transportation and markets to which it hashad access to serve those customers.
As more fully described in Note 6, effective January 1, 2017, we sold all of the equity interests of AEM to CenterPoint Energy Services, Inc. (CES), a subsidiary of CenterPoint Energy Inc. As a result of the sale, Atmos Energy has fully exited the nonregulated natural gas marketing business. Accordingly, these operations have been reported as discontinued operations.

The $9.6$8.5 million quarter-over-quarteryear-over-year increase in net income from discontinued operations primarily reflects the recognition of a net $6.6 million noncash gain from unwinding hedge accounting for certain of the natural gas marketing business's financial positions. Due topositions in connection with the anticipatedsale of AEM. Additionally, we recognized a $2.7 million net gain on sale upon completion of the sale of AEM we determined that the cash flows associated with our natural gas marketing commodity cash flow hedges were no longer probable of occurring; therefore, we discontinued hedge accounting as of December 31, 2016. As a result, we reclassified the gainsto CES in accumulated other comprehensive income associated with the commodity contracts into earnings as a reduction of purchased gas costs and recognized a pre-tax gain of $10.6 million for the three months ended December 31, 2016.January 2017.



Liquidity and Capital Resources
The liquidity required to fund our working capital, capital expenditures and other cash needs is provided from a variety of sources, including internally generated funds and borrowings under our commercial paper program and bank credit facilities. Additionally, we have various uncommitted trade credit lines with our gas suppliers that we utilize to purchase natural gas on a monthly basis. Finally, from time to time, we raise funds from the public debt and equity capital markets to fund our liquidity needs.
We regularly evaluate our funding strategy and capital structure to ensure that we (i) have sufficient liquidity for our short-term and long-term needs in a cost-effective manner and (ii) maintain a balanced capital structure with a debt-to-capitalization ratio in a target range of 45 to 55 percent. We also evaluate the levels of committed borrowing capacity that we require. We currently have over $1.5 billion of capacity under our short-term facilities.
We plan to continue to fund our growth through the use of operating cash flows and debt and equity securities, while maintaining a balanced capital structure. To support our capital market activities, we have a registration statement on file with the SEC that permits us to issue a total of $2.5 billion in common stock and/or debt securities. Under the shelf registration statement, we have filed a prospectus supplement for an at–the-market (ATM) equity distribution program under which we may


issue and sell, shares of our common stock, up to an aggregate offering price of $200 million.
During the first nine months of fiscal 2017, we issued 1,303,494 shares under our ATM program and received net proceeds of $98.8 million. Substantially all shares have now been issued under this program. Additionally, on June 8, 2017, we completed a public offering of $500 million of 3.00% senior unsecured notes due 2027 and $250 million of 4.125% senior unsecured notes due 2044. The net proceeds of approximately $753 million were used to repay our $250 million 6.35% senior unsecured notes at maturity on June 15, 2017 and for general corporate purposes, including the repayment of working capital borrowings pursuant to our commercial paper program. At December 31, 2016,June 30, 2017, approximately $2.4$1.6 billion of securities remain available for issuance under the shelf registration statement and approximately $50 million of equity remained available for issuance under the ATM program.statement.

In June 2017, $250 million of long-term debt will mature. We plan to issue new senior notes to replace this maturing debt. We have executed forward starting interest rate swaps to effectively fix the Treasury yield component associated with this anticipated issuance at 3.37%.
Cash Flows
Our internally generated funds may change in the future due to a number of factors, some of which we cannot control. These include regulatory changes, prices for our products and services, demand for such products and services, margin requirements resulting from significant changes in commodity prices, operational risks and other factors.

Cash flows from operating activities
Period-over-period changes in our operating cash flows are primarily attributable to changes in net income and working capital changes, particularly within our distribution segment resulting from changes in the price of natural gas and the timing of customer collections, payments for natural gas purchases and deferred gas cost recoveries.
For the threenine months ended December 31, 2016,June 30, 2017, we generated cash flow of $117.0$745.6 million from operating activities compared with $70.1$629.9 million for the threenine months ended December 31, 2015.June 30, 2016. The $46.8$115.6 million increase in operating cash flows reflects the positive cash effects of successful rate case outcomes achieved in fiscal 2016 and changes in working capital, primarily reflects favorablethe recovery of deferred purchased gas cost recoveries attributable to higher sales volumes than in the prior-year quarter.costs.
Cash flows from investing activities
In executing our regulatory strategy, we target our capital spending on regulatory mechanisms that permit us to earn an adequate return timely on our investment without compromising the safety or reliability of our system. Substantially all of our regulated jurisdictions have rate tariffs that provide the opportunity to include in their rate base approved capital costs on a periodic basis without being required to file a rate case.
In recent years, a substantial portion of our cash resources has been used to fund our ongoing construction program, which enables us to enhance the safety and reliability of the systems used to provide natural gas distribution services to our existing customer base, expand our natural gas distribution services into new markets, enhance the integrity of our pipelines and, more recently, expand our intrastate pipeline network. Over the last three fiscal years, approximately 80 percent of our


capital spending has been committed to improving the safety and reliability of our system. We anticipate our annual capital spending will be in the range of $1 billion to $1.4 billion through fiscal 2020.
For the threenine months ended December 31, 2016,June 30, 2017, cash used for investing activities was $392.1$747.4 million compared to $290.3$783.4 million in the prior-year period. The $101.8Capital spending increased by $22.5 million, year-over-year change is primarily dueor 2.8 percent, as a result of planned increases in our distribution segment to repair and replace vintage pipe, partially offset by a decrease in spending in our pipeline and storage segment as a result of the substantial completion of an APT project to improve the reliability of gas service to its local distribution company customers. Cash flows from investing activities also include proceeds of $140.3 million received from the sale of AEM, a portion of the proceeds received from the completion of a State of Texas use tax audit and the $86.1 million used to purchase Enlink Pipeline in the first fiscal quarter of EnLink Pipeline for $85.7 million.2017.
Cash flows from financing activities
For the threenine months ended December 31, 2016,June 30, 2017, our financing activities generated $272.3$24.0 million of cash compared with $270.4$191.0 million generated in the prior-year period. The $1.9$167.0 million increase ofdecrease in cash generatedprovided by financing activities is primarily due to borrowings underthe reduction in our three year, $200 million multi-draw floating-rate term loan agreement, proceeds received from the issuance of common stock under our ATM program during the current quarter and the return of cash collateral related to our forward-starting interest rate swaps due toshort-term debt, partially offset by an increase in interest rates in the current period. These additional proceeds resulted in lower net short-term borrowings compared to the prior-year quarter.our long-term debt.

Credit Facilities

Our short-term borrowing requirements are affected primarily by the seasonal nature of the natural gas business and the level of our capital expenditures. Changes in the price of natural gas, the amount of natural gas we need to supply to meet our customers’ needs and our capital spending activities could significantly affect our borrowing requirements. However, our short-term borrowings typically reach their highest levels in the winter months.
We finance our short-term borrowing requirements through a combination of a $1.5 billion commercial paper program fourand three committed revolving credit facilities and one uncommitted revolving credit facility with third-party lenders that provide a total of approximately $1.6$1.5 billion of working capital funding. As of December 31, 2016,June 30, 2017, the amount available to us under our credit facilities, net of commercial paper and outstanding letters of credit, was $0.6$1.3 billion.
Credit Ratings
Our credit ratings directly affect our ability to obtain short-term and long-term financing, in addition to the cost of such financing. In determining our credit ratings, the rating agencies consider a number of quantitative factors, including debt to total capitalization, operating cash flow relative to outstanding debt, operating cash flow coverage of interest and pension liabilities and funding status. In addition, the rating agencies consider qualitative factors such as consistency of our earnings over time, the quality of our management and business strategy, the risks associated with our businesses and the regulatory structures that govern our rates in the states where we operate.
Our debt is rated by threetwo rating agencies: Standard & Poor’s Corporation (S&P), and Moody’s Investors Service (Moody’s) and Fitch Ratings (Fitch). As of December 31, 2016, all threeJune 30, 2017, both rating agencies maintained a stable outlook. Our current debt ratings are all considered investment grade and are as follows:
 S&P Moody’sFitch
Senior unsecured long-term debtA  A2A
Short-term debtA-1  P-1F-2
A significant degradation in our operating performance or a significant reduction in our liquidity caused by more limited access to the private and public credit markets as a result of deteriorating global or national financial and credit conditions could trigger a negative change in our ratings outlook or even a reduction in our credit ratings by the three credit rating


agencies. This would mean more limited access to the private and public credit markets and an increase in the costs of such borrowings.
A credit rating is not a recommendation to buy, sell or hold securities. The highest investment grade credit rating is AAA for S&P and Aaa for Moody’s and AAA for Fitch.Moody’s. The lowest investment grade credit rating is BBB- for S&P and Baa3 for Moody’s and BBB- for Fitch.Moody’s. Our credit ratings may be revised or withdrawn at any time by the rating agencies, and each rating should be evaluated independently of any other rating. There can be no assurance that a rating will remain in effect for any given period of time or that a rating will not be lowered, or withdrawn entirely, by a rating agency if, in its judgment, circumstances so warrant.
Debt Covenants
We were in compliance with all of our debt covenants as of December 31, 2016.June 30, 2017. Our debt covenants are described in greater detail in Note 5 to the unaudited condensed consolidated financial statements.


Contractual Obligations and Commercial Commitments
Except as noted in Note 9 to the unaudited condensed consolidated financial statements, there were no significant changes in our contractual obligations and commercial commitments during the threenine months ended December 31, 2016.June 30, 2017.

Risk Management Activities
In our distribution and pipeline and storage segments, we use a combination of physical storage, fixed physical contracts and fixed financial contracts to reduce our exposure to unusually large winter-period gas price increases. Additionally, we manage interest rate risk by entering into financial instruments to effectively fix the Treasury yield component of the interest cost associated with anticipated financings. Through December 31, 2016, we managed our exposure to the risk of natural gas price changes in our natural gas marketing segment by locking in our gross profit margin through a combination of storage and financial instruments, including futures, over-the-counter and exchange-traded options and swap contracts with counterparties.
The following table shows the components of the change in fair value of our financial instruments for the three and nine months ended December 31, 2016June 30, 2017 and 2015:2016:

Pension and Postretirement Benefits Obligations
For the threenine months ended December 31,June 30, 2017 and 2016, and 2015, our total net periodic pension and other benefits costs were $11.6$34.7 million and $11.5$34.5 million. A substantial portion of those costs relating to our natural gas distribution operations are recoverable through our gas distribution rates; however, a portion of these costs is capitalized into our distribution rate base. The remaining costs are recorded as a component of operation and maintenance expense.
Our fiscal 2017 costs were determined using a September 30, 2016 measurement date. As of September 30, 2016, interest and corporate bond rates were lower than the rates as of September 30, 2015. Therefore, we decreased the discount rate used to measure our fiscal 2017 net periodic cost from 4.55 percent to 3.73 percent. We maintained the expected return on plan assets of 7.00 percent in the determination of our fiscal 2017 net periodic pension cost based upon expected market returns for our targeted asset allocation. As a result of the net impact of changes in these and other assumptions, we expect our fiscal 2017 net periodic pension cost to be generally consistent with fiscal 2016.
The amount with which we fund our defined benefit plan is determined in accordance with the Pension Protection Act of 2006 (PPA) and is influenced by the funded position of the plan when the funding requirements are determined on January 1 of each year. Based upon the determination as of January 1, 2016,2017, we are not required to make a minimum contribution to our defined benefit plan during fiscal 2017. However, in June 2017, we will consider whethermade a voluntary contribution is prudent to maintain certain funding levels.of $5.0 million.
For the threenine months ended December 31, 2016June 30, 2017 we contributed $3.0$9.9 million to our postretirement medical plans. We anticipate contributing a total of between $10 million and $20 million to our postretirement plans during fiscal 2017.


The projected pension liability, future funding requirements and the amount of pension expense or income recognized for the plans are subject to change, depending upon the actuarial value of plan assets in the plans and the determination of future benefit obligations as of each subsequent actuarial calculation date. These amounts will be determined by actual investment returns, changes in interest rates, values of assets in the plans and changes in the demographic composition of the participants in the plans.
