Our distribution business delivers natural gas through sales and transportation arrangements to approximatelyover three million residential, commercial, public authority and industrial customers through our six natural gasregulated distribution divisions, which at June 30, 2017,2018, covered service areas located in eight states.
Our pipeline and storage business, which is also subject to federal and state regulations, includes the transportation of natural gas to our Texas and Louisiana distribution systems and the management of our underground storage facilities used to support Texasour distribution businesses.
Effective January 1, 2017, we completed the sale of all of the equity interests of Atmos Energy Marketing (AEM) to CenterPoint Energy Services, Inc., a subsidiary of CenterPoint Energy, Inc. (CES). Accordingly, AEM’s historical financial results are reflectedbusiness 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 nonregulated 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 Atmos Energy and third parties.various states.

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, which appear in Exhibit 99.1 to our Current Report on Form 8-K dated April 12, 2017 (the "Fiscal 2016 Financial Statements").2017. 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 Fiscal 2016 Financial Statements.Annual Report on Form 10-K for the fiscal year ended September 30, 2017.

During the third quarter, we completed a State of Texas use tax audit that covered the period from October 2011 to March 2017, which resulted in a refund of $29.8 million.

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 6, 2017, our Atmos Pipeline - Texas Division filed its statement of intent seeking $63.6 million, as adjusted in its 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 of our Fiscal 2016 Financial Statements.
As discussed in Note 3, due to the realignment ofconsolidated financial statements in our reportable segments, prior periods' segment information has been recast in accordance with applicable accounting guidance. Additionally, as discussed in Note 6, due toAnnual Report on Form 10-K for the sale of AEM, prior period amounts have been presented as discontinued operations. The segment realignment and the presentation of discontinued operations have not impacted our reported net income, financial position or cash flows. fiscal year ended September 30, 2017.
During the second quarter of fiscal 2017,2018, 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 June 30, 2017,2018, we havehad substantially completed the evaluation of our sources of revenue and are currently assessing the effectimpact that the new guidance will have on our financial position, results of operations, cash flows and 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.
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. Based on the progress of these deliberations to date,this evaluation, we currently do not believe the implementation of the new guidance will have a material effect on our financial position, results of operations, cash flows or business processes. We expect to apply the new guidance using the modified retrospective method on the date of adoption. We are currently still evaluating the transition method we will utilize to adopt the new guidance as well as the impact toon 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 should 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 impactThe standard will require that changes in fair value of thisour available-for-sale equity securities be recorded in net income. The new guidance will be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. We do not anticipate the new standard will have a material impact on our financial position, results of operations andor cash flows. We are currently still evaluating the impact on our financial statement presentation and related disclosures.


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. AsAdditionally, in January 2018, the FASB issued amendments to the standard that provides a practical expedient for entities to not evaluate existing or expired land easements that were not previously accounted for as leases under the current guidance. In July 2018, the FASB issued an amendment to the standard that provides an additional and optional transition method to adopt the standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of June 30, 2017, we had begunretained earnings in the processperiod of identifying and categorizing our lease contracts, evaluating our current business processes and identifying a lease software solution.adoption. We are currently evaluating the effect of this standard and amendments 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 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 Federal Energy Regulatory Commission (“FERC”), which regulates interstate transmission pipelines and also establishes, through its Uniform System of Accounts, accounting practices of rate-regulated entities, has issued guidance that states it will permit an election to either continue to capitalize non-service benefit costs or to cease capitalizing such costs for regulatory purposes.  Accounting guidelines by the FERC are typically also followed by state commissions.  As such, we plan to continue to capitalize all components of net periodic benefit cost for ratemaking purposes and will defer the non-service cost components as a regulatory asset for U.S. GAAP reporting purposes. The new guidance iswill be effective for us in the fiscal year beginning on October 1, 2018 and for interim periods within that year.  The standard requires retrospective application of the amendment related to the presentation of non-service cost components outside of income from operations in the statement of income and prospective application of the change in eligible costs for capitalization. We are currently evaluatingdo not anticipate the potentialnew standard will have a material impact of this new guidance on our financial position, results of operations or cash flows.
In February 2018, the FASB issued new guidance as a result of the Tax Cuts and Jobs Act of 2017 (the "TCJA"), related to the treatment of certain tax effects from accumulated other comprehensive income. The new guidance allows entities to reclassify from accumulated other comprehensive income to retained earnings the stranded tax effects resulting from the adoption of the TCJA. The new guidance will be effective for us in the fiscal year beginning on October 1, 2019 and for interim periods within that year. Early adoption is permitted, including adoption in any interim period for public business entities for reporting periods for which financial statements have not yet been issued and should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. We plan to early adopt the new standard effective as of September 30, 2018, and reclassify the stranded tax effects resulting from the TCJA from accumulated other comprehensive income to retained earnings. We do not anticipate the new standard will have a material impact on our financial position, results of operations or 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 alla portion of our regulatory liabilities are recorded as a component of other current liabilities and deferred credits and other liabilities. Deferred gas costs are recorded either in other current assets or liabilities and theour regulatory excess deferred taxes and regulatory cost of removal obligation is reported separately.

(2)Infrastructure mechanisms in Texas and Louisiana allow for the deferral of all eligible expenses associated with capital expenditures incurred pursuant to these rules, including the recording of interest on deferred expenses until the next rate proceeding (rate case or annual rate filing), at which time investment and costs would be recoverable through base rates.

(3)The TCJA resulted in the remeasurement of the net deferred tax liability included in our rate base. Of this amount, $4.2 million is recorded in Other current liabilities. The period and timing of the return of the excess deferred taxes is being determined by regulators in each of our jurisdictions. See Note 6 for further information.
(4)Effective January 1, 2018, regulators in each of our service areas required us to establish a regulatory liability for the difference in recoverable federal taxes included in revenues based on the former 35% federal statutory rate and the new 21% federal statutory rate for service provided on or after January 1, 2018. The period and timing of the return of this liability to utility customers is being determined by regulators in each of our jurisdictions. See Note 6 for further information.



3.    Segment Information

Through November 30, 2016, our consolidated operations were managed We manage 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 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 have been managing and reviewingreview 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.Louisiana.
The natural gas marketing segment iswas comprised of our discontinued natural gas marketing business.

Our determination of reportable segments considers the strategic operating units under which we manage sales of various products and services 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, they 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 Fiscal 2016 Financial Statements.Annual Report on Form 10-K for the fiscal year ended September 30, 2017. We evaluate performance based on net


income or loss of the respective operating segments.units. 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' Income taxes are allocated to each segment information has been recast as required by applicable accounting guidance. The segment realignment has not impacted our reported consolidated revenues or net income. 


if each segment’s taxes were calculated on a separate return basis.

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 June 30, 20172018 and 20162017 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 was used to repay short-term debt and for working capital, capital expenditures and other general corporate purposes. At June 30, 2017, there was $125.0 million outstanding under the
(1)
Up to $200 million can be drawn under this term loan.
We utilize short-term debt to fund ongoing workingprovide cost-effective, short-term financing until it can be replaced with a balance of long-term debt and equity financing that achieves the Company’s desired capital needs, such as our seasonal requirements for gas supply, general corporate liquiditystructure with an equity-to-total-capitalization ratio between 50% and capital expenditures.60%, inclusive of long-term and short-term debt. 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 financeCurrently, our short-term borrowing requirements are satisfied through a combination of a $1.5 billion commercial paper program and three committed revolving credit facilities with third-party lenders that provide approximately $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 expiresfacility. On March 26, 2018, we executed one of our two one-year extension options which extended the maturity date from September 25, 2021.2021 to September 25, 2022. 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 loan, total committed loanavailability to $1.75 billion. This facility was amended in October 2016 to increase the total availability from $1.25 billion. At June 30, 20172018 and September 30, 20162017, a total of $258.6$244.8 million and $829.8$447.7 million was outstanding under our commercial paper program.



Additionally, we have a $25 million 364-day unsecured facility, which was renewed oneffective April 1, 2017,2018 and expires March 31, 2019, and a $10 million 364-day unsecured revolving credit facility, which is used primarily to issue letters of credit. At June 30, 2017,2018, 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$4.4 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 capitalizationtotal-debt-to-total-capitalization of no greater than 70 percent. At June 30, 2017,2018, our total-debt-to-total-capitalization ratio, as defined in the agreements, was 4742 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 June 30, 2017.2018. 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.
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.
6.    DivestituresImpact of the Tax Cuts and AcquisitionsJobs Act of 2017
DivestitureOn December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the "TCJA") was signed into law. The TCJA introduced several significant changes to corporate income tax laws in the United States. The most significant change that affects 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 allis the reduction of the equity interestsfederal statutory income tax rate from 35% to 21%. As a rate-regulated entity, the accelerated capital expensing and the limitation on interest deductibility provisions included in the TCJA are not applicable to us.
Under generally accepted accounting principles, we use the asset and liability method of AEM.accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.
At September 30, 2017, we measured our net deferred tax liability using the enacted federal statutory tax rate of 35%. The transaction closedenactment of the TCJA on January 3,December 22, 2017 with an effective daterequired us to remeasure our deferred tax assets and liabilities, including our U.S. federal income tax net operating loss carryforwards, at the newly enacted federal statutory income tax rate. As the Company’s fiscal year end is September 30, the Internal Revenue Code requires the Company to use a blended statutory federal corporate income tax rate of January 1, 2017. CES paid a cash purchase price of $38.3 million plus working capital of $109.0 million24.5% for total cash consideration of $147.3fiscal 2018.
The decrease in the federal statutory income tax rate reduced our net deferred tax liability by $903.7 million. Of this amount, $7.0$738.2 million was placed into escrowrelates to regulated operations and has been recorded as a regulatory liability, a portion of which is currently being returned to utility customers. The period and timing of these revenue adjustments are subject to Internal Revenue Code provisions and regulatory actions in each of the eight states in which we operate. During the third quarter of fiscal 2018, the Company amortized $0.5 million of this regulatory liability. The remaining $165.5 million has been reflected as a one-time income tax benefit in our condensed consolidated statement of income for the nine months ended June 30, 2018, because these taxes are not related to our cost of service ratemaking.
At June 30, 2018, we had $270.7 million of remeasured federal net operating loss carryforwards. The federal net operating loss carryforwards are available to offset future taxable income and will begin to expire in 2029. The Company also has $10.1 million of federal alternative minimum tax credit carryforwards that do not expire and are expected to be paidfully refunded to us between 2019 and 2022 as a result of changes introduced by the TCJA. These credit carryforwards are now reflected as taxes receivable within the deferred charges and other assets line item on our condensed consolidated balance sheet. In addition, the Company has $5.3 million in remeasured charitable contribution carryforwards to offset future taxable income. The Company’s charitable contribution carryforwards expire between 2018 and 2023.
The Company also has $21.2 million of state net operating loss carryforwards and $1.5 million of state tax credit carryforwards (net of $5.6 million and $0.4 million of remeasured federal effects). Depending on the jurisdiction in which the state net operating loss was generated, the carryforwards will begin to expire between 2018 and 2032.
Due to the changes introduced by the TCJA, we now believe it is more likely than not that the benefit from certain charitable contribution carryforwards for which a valuation allowance was previously established will be realized. As a result, we reduced our valuation allowance by $4.2 million during the first quarter. This amount is included in the $165.5 million one-time income tax benefit.
The SEC issued guidance in Staff Accounting Bulletin 118 (SAB 118), which allows us to record provisional amounts during a one-year measurement period, similar to the measurement period in accounting for business combinations. The Company within 24 monthshas determined a reasonable estimate for the measurement and accounting for certain effects of the closing date,TCJA, including the remeasurement of our net deferred tax liabilities and the establishment of any indemnification claims agreeda regulatory liability, which have been reflected as provisional amounts in the June 30, 2018 condensed consolidated financial statements and are described in further detail above. The amounts represent our best estimates based upon betweenrecords, information and current guidance. We are still analyzing certain aspects of the two companies. TCJA, refining our calculations and expecting additional guidance relating to the TCJA from the U.S. Department of the Treasury and the Internal Revenue Service.  Any additional guidance issued or future actions of our


regulators could potentially affect the final determination of the accounting effects arising from the implementation of the TCJA.
We recognizedare actively working with our regulators in each jurisdiction to address the impact of the TCJA on our cost of service based rates. Accounting orders were issued for all our service areas that required us to establish, effective January 1, 2018, a net gainseparate regulatory liability for the difference in taxes included in our rates that have been calculated based on a 35% statutory income tax rate and the new 21% statutory income tax rate. The establishment of $0.03 per diluted share on the salethis regulatory liability relating to our cost of service rates resulted in a reduction to our revenues beginning in the second quarter of fiscal 20172018. The period and completedtiming of the return of these liabilities to utility customers is being determined by regulators in each of our jurisdictions. As of June 30, 2018, this regulatory liability was $30.9 million.
We have received approval from regulators to update our cost of service rates to reflect the decrease in the statutory income tax rate in our Colorado, Kansas, Kentucky, Louisiana and Texas service areas. We are still working capital true–up duringwith regulators in Mississippi, Tennessee and Virginia to reflect the effects of the lower statutory income tax rate in our cost of service in rates. During the third 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 income2018, we received approval from discontinued operations, net of income tax.  Accordingly, expensesregulators to return amounts to customers related to allocable general corporate overhead and interest expense are not includedthe regulatory liabilities recorded for differences in these results.  The decisionour cost of service rates due to report this segment as a discontinued operation was predicated, in part, on the following qualitative and quantitative factors:  1) the disposal resultedchange in the company becoming a fully regulated entity; 2)federal statutory income tax rate in Colorado and Kansas, in accordance with regulatory proceedings within one year.
During the fact that an entire reportable segment was disposedthird quarter 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 information2018, we received approval from regulators to return amounts to customers related to assets,the regulatory liabilities and operating results related to discontinued operations. Operating expenses include operation and maintenance expense, provisionrecorded for doubtful accounts, depreciation and amortization expense andthe excess deferred taxes other than income. Additionally, assets and liabilities related to our natural gas marketing operations are classified as “held for sale” on our consolidated balance sheet 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.

In the second quarter of fiscal 2018, due to the retirement of certain executives, we recognized a settlement loss of $2.4 million associated with our Supplemental Executive Retirement Plan and revalued the net periodic pension cost for the remainder of fiscal 2018. The revaluation of the net periodic pension cost for our Supplemental Executive Retirement Plan resulted in an increase in the discount rate, effective March 1, 2018, to 4.12% from 3.89%, which will increase our net periodic pension cost by approximately $0.1 million for the remainder of the fiscal year.

The assumptions used to develop our net periodic pension cost for the three and nine months ended June 30, 20172018 and 20162017 are as follows:
 Pension Benefits Other Benefits Supplemental Executive Retirement Plan Pension Benefits Other Benefits
 2017 2016 2017 2016 2018 2017 2018 2017 2018 2017
Discount rate 3.73% 4.55% 3.73% 4.55% 4.29% 3.73% 3.89% 3.73% 3.89% 3.73%
Rate of compensation increase 3.50% 3.50% N/A N/A 3.50% 3.50% 3.50% 3.50% N/A N/A
Expected return on plan assets 7.00% 7.00% 4.45% 4.45% N/A N/A 6.75% 7.00% 4.29% 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, 2017.2018. Based on that determination, we are not required to make a minimum contribution to our defined benefit plan during fiscal 2017;2018; however, we mademay consider whether a voluntary contribution of $5.0 million during the third quarter of fiscal 2017.is prudent to maintain certain funding levels.
We contributed $9.9$11.4 million to our other post-retirement benefit plans during the nine months ended June 30, 2017.2018. We expect to contribute a total of between $10 million and $20 million to these plans during fiscal 2017.2018.
9.    Commitments and Contingencies
Litigation and Environmental Matters
With respectIn the normal course of business, we are subject to various legal and regulatory proceedings. For such matters, we record liabilities when they are considered probable and estimable, based on currently available facts, our historical experience, and our estimates of the ultimate outcome or resolution of the liability in the future. While the outcome of these proceedings is uncertain and a loss in excess of the amount we have accrued is possible though not reasonably estimable, it is the opinion of management that any amounts exceeding the accruals will not have a material adverse impact on our financial position, results of operations or cash flows.


We maintain liability insurance for various risks associated with the operation of our natural gas pipelines and facilities, including for property damage and bodily injury. These liability insurance policies generally require us to be responsible for the first $1.0 million (self-insured retention) of each incident.
The National Transportation Safety Board (NTSB) is investigating an incident that occurred at a Dallas, Texas residence on February 23, 2018 that resulted in one fatality and injuries to four other residents. Together with the Railroad Commission of Texas and the Pipeline and Hazardous Materials Safety Administration, Atmos Energy is a party to the specific litigationinvestigation and environmental-related matters or claimsin that were disclosedcapacity is working closely with the NTSB to help determine the cause of this incident.
On March 29, 2018, a civil action was filed in Note 11 of our Fiscal 2016 Financial Statements, there were no material changesDallas, Texas against Atmos Energy in response to the status of such litigationFebruary 23rd incident. The plaintiffs seek over $1.0 million in damages for, among with others, wrongful death and environmental-related matters or claims during the nine months ended June 30, 2017.personal injury.
We are a party to various other 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 distribution divisions 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 hubs. At June 30, 2017,2018, we were committed to purchase 53.253.6 Bcf within one year 37.6and 51.2 Bcf within two to three 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 June 30, 2017,2018, formula rate mechanisms were pending regulatory approval in our Louisiana, Mid-Tex, Tennessee and West Texas service area,areas, infrastructure mechanisms were pending regulatory approval in our Mississippi and Virginia service areasarea and rate cases were pending regulatory approval in our Colorado service areaMid-Tex, Virginia and West Texas service area related to APT.areas. These regulatory proceedings are discussed in further detail below in Management’s Discussion and Analysis — Recent Ratemaking Developments. Additionally, as discussed in further detail in Note 6, all jurisdictions are addressing impacts of the TCJA.
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 ofto the consolidated financial statements in our Fiscal 2016 Financial Statements.Annual Report on Form 10-K for the fiscal year ended September 30, 2017. During the nine months ended June 30, 2017, except for the change in the scope of our natural gas marketing commodity risk management activities as a result of the sale of AEM,2018, 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 2016-20172017-2018 heating season (generally October through March), in the jurisdictions where we are permitted


to utilize financial instruments, we hedged approximately 2726 percent, or 16.215.0 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. Effective January 1, 2017, as a result of the sale of AEM, these activities were discontinued.
Due to 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 gain in accumulated other comprehensive income associated with the commodity contracts into earnings as a reduction of purchased gas cost and recognized a pre-tax gain of $10.6 million, which is included in income from discontinued operations on the condensed consolidated statement of 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 June 30, 2017,2018, we had forward starting interest rate swaps to effectively fix the Treasury yield component associated with the anticipated issuance of $450 million unsecured senior notes in fiscal 2019 at 3.78%, which we designated as a cash flow hedge at the time the swaps were executed. As of June 30, 2017,2018, we had $41.5$48.7 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 June 30, 2017,2018, 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 June 30, 2017,2018, we had 18,83311,446 MMcf of net shortlong commodity contracts outstanding. These contracts have not been designated as hedges.

Impact of Financial Instruments on the Income Statement
Hedge ineffectiveness forCash Flow Hedges
As discussed above, our natural gas marketingdistribution segment was recordedhas interest rate swap agreements, which we designated as a component of purchased gas cost, which is included in discontinued operationscash flow hedge at the time the swaps were executed. The net loss on thesettled interest rate agreements reclassified from AOCI into interest charges on our condensed consolidated statements of income and primarily results from differences in the location and timing of the derivative instrument and the hedged item. Forfor the three months ended June 30, 2016, we recognized a gain arising from fair value2018 and cash flow hedge ineffectiveness of $13.6 million. For2017 was $0.6 million and $0.2 million and for the nine months ended June 30, 2018 and 2017 and 2016, we recognized gains arising from fair value and cash flow hedge ineffectiveness of $3.4was $1.8 million and $18.1$0.5 million. Additional information regarding ineffectiveness recognized in the income statement is included in the tables below.
Fair Value Hedges
The impact of our natural gas marketing segment commodity contracts designated as fair value hedges and the related hedged item on the results of discontinued operations on our condensed consolidated income statement for the three and nine months ended June 30, 2017 and 2016 is presented 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.

Financial Instruments Not Designated as Hedges
The impact of the natural gas marketing segment's financial instruments that had not been designated as hedges on our condensed consolidated income statements for the three months ended June 30, 2016 was a decrease in purchased gas cost of $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 ofto the financial statements in our Fiscal 2016 Financial Statements.Annual Report on Form 10-K for the fiscal year ended September 30, 2017. During the nine months ended June 30, 2017,2018, 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 ofto the financial statements in our Fiscal 2016 Financial Statements.Annual Report on Form 10-K for the fiscal year ended September 30, 2017.
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 June 30, 20172018 and September 30, 2016.2017. Assets and liabilities are categorized in their entirety based on the lowest level of input that is significant to the fair value measurement.

(1)Our Level 2 measurements consist of over-the-counter options and swaps, which are valued using a market-based approach in which observable market prices are adjusted for criteria specific to each instrument, such as the strike price, notional amount or basis differences, municipal and corporate bonds, which are valued based on the most recent available quoted market prices and money market funds whichthat are valued at cost.

(2)This column reflects adjustments to our gross financial instrument assets and liabilities to reflect netting permitted under our master netting agreements and the relevant authoritative accounting literature. As of September 30, 2016, we had $50.4 million of cash held in margin accounts to collateralize certain financial instruments. Of this amount, $43.6 million was used to offset current and noncurrent risk management liabilities under master netting arrangements with the remaining $6.8 million classified as current risk management assets.

At June 30, 20172018 and September 30, 2016,2017, our available-for-sale securities included $42.3$45.7 million and $41.3$42.9 million related to assets held in separate rabbi trusts for our supplemental executive benefit plans. At June 30, 2017,2018, we maintained investments in bonds that have contractual maturity dates ranging from July 20172018 through December 2020.June 2021.
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. The following table presents the carrying value and fair value of our debt as of June 30, 20172018 and September 30, 2016:2017:

Information regarding our concentration of credit risk is disclosed in Note 16 ofto the financial statements in our Fiscal 2016 Financial Statements. ExceptAnnual Report on Form 10-K for the sale of AEM, duringfiscal year ended September 30, 2017. During the nine months ended June 30, 2017,2018, there were no material changes in our concentration of credit risk.
13. Discontinued Operations
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 Atmos Energy Marketing, LLC (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 working capital of $109.0 million for total cash consideration of $147.3 million. Of this amount, $7.0 million was placed into escrow and was to be paid to the Company within 24 months of the closing date, net


of any indemnification claims agreed upon between the two companies. In January 2018, $3.0 million of this escrowed amount was released and received by the Company. We recognized a net gain of $0.03 per diluted share on the sale in the second quarter of fiscal 2017 and completed the working capital true–up during the third quarter of fiscal 2017.
The operating results of our natural gas marketing reportable segment have been reported on the condensed consolidated statement of income as income from discontinued operations, net of income tax, for the nine months ended June 30, 2017.  Accordingly, expenses related to allocable general corporate overhead and interest expense are not included in these results. 
The tables below set forth selected financial information related to discontinued operations. Operating expenses include operation and maintenance expense, provision for doubtful accounts, depreciation and amortization expense and taxes, other than income. At June 30, 2018 and September 30, 2017 we did not have any assets or liabilities held for sale.

Natural Gas Marketing Commodity Risk Management Activities
Our discontinued 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. Effective January 1, 2017, as a result of the sale of AEM, these activities were discontinued.
Due to 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 gain in accumulated other comprehensive income associated with the commodity contracts into earnings as a reduction of purchased gas cost and recognized a pre-tax gain of $10.6 million, which is included in income from discontinued operations on the condensed consolidated statement of income for the nine months ended June 30, 2017.
The Company's other risk management activities are discussed in Note 10.
Impact of Financial Instruments on the Income Statement
Hedge ineffectiveness for our natural gas marketing segment was 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. For the nine months ended June 30,


2017, we recognized a gain arising from fair value and cash flow hedge ineffectiveness of $3.4 million. Additional information regarding ineffectiveness recognized in the income statement is included in the tables below.
Fair Value Hedges
The impact of our natural gas marketing segment commodity contracts designated as fair value hedges and the related hedged item on the results of discontinued operations on our condensed consolidated income statement for the nine months ended June 30, 2017 is presented below.

OVERVIEW
Atmos Energy and our subsidiaries are engaged primarily in the regulated natural gas distribution and transmissionpipeline and storage businesses, as well as our natural gas marketing business through December 31, 2016.businesses. We distribute natural gas through sales and transportation arrangements to approximatelyover three million residential, commercial, public authority and industrial customers throughout our six distribution divisions, which at June 30, 20172018 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 business 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.

We 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.
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 included in our former nonregulated segment.Louisiana.
The natural gas marketing segment iswas 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 CurrentAnnual Report on Form 8-K dated April 12,10-K for the fiscal year ended September 30, 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 nine months ended June 30, 2017.2018.

Non-GAAP Financial MeasureMeasures
Our operations are affected by the cost of natural gas. The cost of gas, which 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,contribution margin, 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 amore useful and more relevant measure to analyze our financial performance.performance than operating revenues. As such, the following discussion and analysis of our financial performance will reference gross profitcontribution margin rather than operating revenues and purchased gas cost individually. Further, the term contribution margin is not intended to represent operating income, the most comparable GAAP financial measure, as an indicator of operating performance and is not necessarily comparable to similarly titled measures reported by other companies.
As described further in Note 6, the enactment of the Tax Cuts and Jobs Act of 2017 (the "TCJA") required us to remeasure our deferred tax assets and liabilities at our new federal statutory income tax rate as of December 22, 2017. The remeasurement of our net deferred tax liabilities resulted in the recognition of a non-cash income tax benefit of $165.5 million for the nine months ended June 30, 2018. Due to the non-recurring nature of this benefit, we believe that income from continuing operations and diluted earnings per share from continuing operations before the non-cash income tax benefit provide a more relevant measure to analyze our financial performance than income from continuing operations and consolidated diluted earnings per share from continuing operations. Accordingly, the following discussion and analysis of our financial performance will reference adjusted income from continuing operations and diluted earnings per share, which is calculated as follows:

RESULTS OF OPERATIONS

Executive Summary
Atmos Energy strives to operate itsour businesses safely and reliably while delivering superior shareholder value. In recent years, weOur commitment to modernizing our natural gas distribution and transmission systems requires a significant level of capital spending. We have implementedthe ability to begin recovering a significant portion of these investments timely through rate designs and mechanisms 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 reliabilityThe execution of our natural gas distribution and transmission infrastructure. This increased level of investment and timely recovery ofcapital spending program, the ability to recover these investments throughtimely and our regulatory mechanisms has resulted in increased earnings and operating cash flows in recent years.
The pursuit ofability to access the capital markets to satisfy our strategy wasfinancing needs are the primary driver fordrivers that affect 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 $140.3 million in cash proceeds, including working capital. We recorded 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 were 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 in the tables below:financial performance.

Net income from continuing operations increased 12 percent, compared 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 nine months ended June 30, 2017,2018, we recorded income from continuing operations of $564.3 million, or $5.09 per diluted share, compared to income from continuing operations of $346.9 million, or $3.27 per diluted share for the nine months ended June 30, 2017.
After adjusting for the nonrecurring benefit recognized after implementing the TCJA, we recorded adjusted income from continuing operations of $398.8 million, or $3.60 per diluted share for the nine months ended June 30, 2018, compared to adjusted income from continuing operations of $346.9 million, or $3.27 per diluted share for the nine months ended June 30, 2017. The period-over-period increase of $51.9 million, or 15 percent, largely reflects positive rate outcomes, weather that was 36 percent colder than the prior year, customer growth in our distribution segmentbusiness and the impact of the TCJA on our effective income tax rate, partially offset by reduced revenues as a result of implementing the TCJA. During the nine months ended June 30, 2018, we completed 1718 regulatory proceedings, resulting in an increase in annual operating income of $85.0$82.0 million and had fournine ratemaking efforts in progress at June 30, 20172018, seeking $17.1 million of additional annual operating income. Additionally, on January 6, 2017, our Atmos Pipeline - Texas Division filed its statement of intent 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 a $13 milliontotal increase in annual operating income. Our discontinued natural gas marketing results for the nine months ended June 30, 2017 primarily include a pre-tax gainincome of $10.6 million recognized in the first fiscal quarter related to the discontinuance of cash flow hedging for our natural gas marketing commodity contracts and a $2.7 million net gain on sale recognized in January 2017 upon completion of the sale.$36.0 million.
Capital expenditures for the first nine months of fiscal 20172018 were $812.1 million. Approximately 82$1.1 billion. Over 80 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 $1.25total approximately $1.4 billion for fiscal 2017.2018. We funded our capital expenditureexpenditures program primarily through operating cash flows of $745.6 million.$1.0 billion. Additionally, we issued approximately $885 million of long-term debt and $100$400 million of common stock during the nine month period endingmonths ended June 30, 2017.2018. The net proceeds from these issuances wasthe issuance were primarily used to repay maturing long-termshort-term debt under our commercial paper program, to fund capital spending 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 APT intrastate pipeline to serve transportation customers in North Texas, which continues to experience significant population growth.general corporate purposes.
As a result of our sustained financial performance, improved cash flows and capital structure, our Board of Directors increased the quarterly dividend by 7.17.8 percent for fiscal 2017.2018.
TCJA Impact
The TCJA introduced several significant changes to corporate income tax laws in the United States, which have been reflected in our condensed consolidated financial statements for the period ended June 30, 2018. As a rate regulated entity, the effects of lower tax rates included in our cost of service rates will ultimately flow through to our utility customers in the form of adjusted rates. Therefore, the favorable impact of the reduction in our federal statutory income tax rate on our financial performance will be limited to items that impact our income before income taxes in the current period that have not yet been reflected in our rates (most notably increases to and decreases in commission-approved regulatory assets and liabilities recorded on our condensed consolidated balance sheet) and market-based revenues that are earned from customers who utilize our assets. Note 6 to the condensed consolidated financial statements details the various impacts of the TCJA on our financial position and results from operations. The most significant changes are summarized as follows:
Because our fiscal year started on October 1, 2017, our federal statutory income tax rate for fiscal 2018 was reduced from 35% to 24.5%. We anticipate our effective income tax rate for fiscal 2018 will range from 26% to 28%, before the effect of the return of the excess deferred tax liability and the one-time, non-cash income tax benefit. Our federal statutory income tax rate will decline to 21% on October 1, 2018.
As a result of implementing the TCJA, we remeasured our net deferred tax liability using our new federal statutory income tax rate, which reduced our net deferred tax liability by $903.7 million. Of this amount, $738.2 million was reclassified to a regulatory liability, which will be, and as discussed further below is being returned to utility customers in some of our jurisdictions. During the third quarter of fiscal 2018, we amortized $0.5 million of this regulatory liability. The remaining $165.5 million was recognized as a one-time, non-cash income tax benefit in our condensed consolidated statement of income for the nine months ended June 30, 2018.
Atmos Energy supports our regulators' efforts to ensure our utility customers receive the full benefits of changes in our cost of service rates arising from tax reform. Income taxes, like other costs, are passed through to our customers in our rates; however, changes to customer rates must be approved by our regulators. Beginning in the second quarter of fiscal 2018, we established regulatory liabilities in all our jurisdictions for the difference in taxes included


in our cost of service rates that have been calculated based on a 35% statutory income tax rate and a 21% statutory income tax rate, which reduced our revenues. As described in Note 6, as of June 30, 2018, we have received approval from most of our regulators to adjust customer rates for the lower statutory income tax rate. We have also received approval from regulators in Colorado and Kansas to return amounts to customers related to the regulatory liability recorded for differences in our cost of service rates due to the change in the statutory income tax rate within one year. Additionally, in Colorado, Louisiana and Kentucky, we have received approval from regulators to return the excess deferred taxes created upon implementation of the TCJA over a period ranging from 18 to 40 years. In our remaining jurisdictions, the treatment of the effects of the TCJA in rates is being addressed in ongoing or future regulatory proceedings.
The enactment of the TCJA is expected to reduce our cash flows from operations primarily due to 1) the collection of taxes at a lower rate and 2) the return of regulatory liabilities established in response to the enactment of the TCJA and regulatory activities to our utility customers. We intend to externally finance this reduction in operating cash flow in a balanced fashion in order to maintain an equity-to-total-capitalization ratio ranging from 50% to 60% to maintain our current credit ratings. We currently anticipate this external financing need will range from a total of $500 million to $600 million through fiscal 2022.
The following discusses the results of operations for each of our operating segments.
Distribution Segment
The distribution segment is primarily comprised of our regulated natural gas distribution and related sales operations in eight states. 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. Gross profitContribution margin 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,contribution margin, 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.contribution margin. 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 7576 percent of our residential and commercial margins.

Income before income taxes for our distribution segment increased 20decreased 19 percent, primarily due to a $19.0 million increase in gross profit, partially offset with a $5.6$23.6 million increase in operating expenses.expenses, partially offset by an $8.3 million increase in contribution margin. The quarter-over-quarter increase in gross profitcontribution margin primarily reflects:
a $13.7an $11.2 million net increase in rate adjustments, before the effect of the TCJA, primarily in our Mid-Tex West Texas, Louisiana and MississippiKentucky/Mid-States Divisions.
Customer growth,a $4.2 million increase in revenue-related taxes primarily in our Mid-Tex Division, which contributed an incremental $1.1 million.offset by a corresponding $7.3 million increase in the related tax expense.
a $1.8$2.7 million net increase in residential and commercial consumption,transportation margin primarily in our Mid-TexKentucky/Mid-States Division.
a $12.4 million decrease in contribution margin due to the inclusion of the lower statutory federal income tax rate in our revenues due to implementation of the TCJA.
The increase in operating expenses, which includes operation and maintenance expense, provision for doubtful accounts, depreciation and amortization expense and taxes, other than income, was primarily dueis attributable to higheran increase in employee-related costs, incremental system integrity activities and increased depreciation and property tax expensetaxes associated with increased capital investments,investments.
The decrease in income tax expense reflects a reduction in our effective tax rate from 37.7% to 25.2%, as well as higher administrative expenses.a result of the TCJA.

The year-over-year increase in gross profitcontribution margin primarily reflects:

Customer growth,a $14.2 million increase in residential and commercial net consumption, primarily in our Mid-Tex and Tennessee service areas, which contributed an incremental $5.4 million.Kentucky/Mid-States Divisions.

a $4.2an $8.6 million increase in transportation margin primarily in our Kentucky/Mid-States Mid-Tex and West Texas Divisions.Division.
a $2.1$5.8 million net increase in residential consumption,from customer growth, primarily in our Mid-Tex Division.
a $38.7 million decrease in contribution margin due to the inclusion of the lower statutory federal income tax rate in our revenues due to implementation of the TCJA. Of this amount, $17.3 million has been reflected in customer


bills. The remaining $21.4 million relates to the establishment of regulatory liabilities for the difference between the former 35% federal statutory income tax rate and the current 21% rate.
The increase in operating expenses largely reflects expenses incurred after we decided to undertake a planned outage of our natural gas distribution system in Northwest Dallas. In late February 2018, there were gas-related incidents in Northwest Dallas, one of which includes operationresulted in a fatality and maintenance expense, provision for doubtful accounts, depreciationinjuries to four other residents.  The National Transportation Safety Board (NTSB) is investigating the latter incident. Together with the Railroad Commission of Texas and amortization expensethe Pipeline and taxes,Hazardous Materials Safety Administration, we are a party to the investigation and in that capacity we are working closely with the NTSB to help determine the cause of this incident.  On March 1, 2018, we initiated a planned outage of a portion of our natural gas distribution system in Northwest Dallas that affected approximately 2,400 homes.  The outage was initiated after we experienced a sudden and unexplainable increase in leaks in this confined geographic area in less than a week’s time.  Based upon our preliminary assessment, we believe an extraordinary combination of events and circumstances that could not have been predicted, anticipated, readily modeled or foreseen damaged our pipeline system in that area.  These events and circumstances, include, but are not limited to, geology, hydrology, soil conditions and record rainfall.  The system was replaced and placed into service by March 31, 2018.  While the system was replaced, we provided financial assistance to the affected residents and incurred other than income, was primarily duerelated costs of approximately $24 million.
The remaining increase in operating expenses is attributable to an increase in employee-related costs, higher levels of line locate and pipelineincremental system integrity activities primarily in our Mid-Tex Division, and higherincreased depreciation and property tax expensetaxes associated with increased capital investments.
The decrease in income tax expense reflects a reduction in our effective tax rate from 37.2% to 26.8%, as a result of the TCJA.

Recent Ratemaking Developments
The amounts described in the following sections represent the operating income that was requested or received in each rate filing, which may not necessarily reflect the stated amount referenced in the final order, as certain operating costs may have changed as a result of a commission’s or other governmental authority’s final ruling. During the first nine months of fiscal 2017,2018, we completed 1716 regulatory proceedings, resulting in ana $85.010.8 million increase in annual operating income as summarized below. The recent ratemaking activities and changes to operating income discussed below that include the impacts of tax reform are not reflective of the true economic benefit of the rate case outcome as it does not include the corresponding benefit we will receive in income tax expense due to the decrease in our statutory tax rate from 35% to 21%.

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 ofthe service areas in 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:

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.Louisiana. 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 western Texas, extending into or near the major producing areas of the Barnett Shale, the Texas Gulf Coast and the Delaware and Midland 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 facilities in Texas.
Our natural gas transmission operations in Louisiana are comprised of a proprietary 21-mile pipeline located in the New Orleans, Louisiana area 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. We also manage two asset management plans, 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 Texas 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 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 statementFollowing the conclusion of intent at least once every five years to review its costs and expenses, including capital costs filed for recovery under GRIP. However,rate case in August 2017, APT is precluded from submittingmade a GRIP filing untilthat covered changes in net investment from October 1, 2016 through December 31, 2016 with a final order has been issued onrequested increase in operating income of $29.0 million. On December 5, 2017, the


statement of intent. Accordingly, filing was approved. On February 15, 2018, APT has not yet submitted its annualmade a GRIP filing for calendar year 2016. Onthat covered changes in net investment from January 6, 2017, APT filed its statement of intent seeking $63.6 million, as adjusted in its rebuttal case, in additional annual operating income. On August 1, 2017 through December 31, 2017 with a final order was issued resulting in a $13 millionrequested increase in annual operating income.income of $42.2 million. On May 22, 2018, the filing was approved.
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 expires in September 2017.

NetIncome before income taxes for our pipeline and storage segment decreased fourfive percent, primarily due to a $2.9$13.4 million increase in operating expenses, partially offset by a $1.7an $11.0 million increase in gross profit.contribution margin. The increase in gross profit iscontribution margin primarily reflects:
a $23.7 million increase in rates from the result of higher through system revenue of $1.3 million, largely related to incremental throughput onapproved APT rate case and the EnLink Pipeline, which was acquiredGRIP filings approved in the first quarter of fiscalDecember 2017 and higher basis spreadsMay 2018.
an $8.0 million decrease in contribution margin due to increased production in the Permian Basin. As noted above, as a resultinclusion of the annuallower statutory federal income tax rate case, we did not filein our annual GRIP filing duringrevenues due to implementation of the second quarterTCJA. Of this amount, $3.1 million has been reflected in customer bills.

Operating expenses which includes operation and maintenance expense, provision for doubtful accounts, depreciation and amortization expense and taxes, other than income, increased $2.9$13.4 million, primarily due to higher depreciation expense and property taxes associated with increased capital investments and higher system maintenance expense.
The decrease in income tax expense reflects a reduction in our effective tax rate from 35.6% to 28.8%, as a result of the acquisition of EnLink Pipeline.TCJA.

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 was to aggregate and purchase gas supply, arrange transportation and storage logistics and ultimately deliver gas to customers at competitive prices. Additionally, AEM utilized proprietary and customer–ownedcustomer-owned transportation and storage assets to provide various services its customers requested. AEM served most of its customers under contracts generally having one to two year terms. As a result, AEM’s margins arose from the types of commercial transactions it had structured with its customers and its ability to identify the lowest cost alternative among the natural gas supplies, transportation and markets to which it had access to serve those customers.
As more fully described in Note 6,13, 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, thesea gain on sale from discontinued operations have beenfor $2.7 million was recorded and net income of $11.0 million for AEM is reported as discontinued operations.

The $8.5 million year-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 in connection with the sale of AEM. Additionally, we recognized a $2.7 million net gain on sale upon completion of the sale of AEM to CES in January 2017.



Liquidity and Capital Resources
The liquidity required to fund our working capital, capital expenditures and other cash needs is provided from a varietycombination of sources, including internally generated fundscash flows and borrowings under ourexternal debt and equity financing. External debt financing is provided primarily through the issuance of long-term debt, a $1.5 billion commercial paper program and bankthree committed revolving credit facilities.facilities with a total availability from third-party lenders of approximately $1.5 billion. The commercial paper program and credit facilities provide cost-effective, short-term financing until it can be replaced with a balance of long-term debt and equity financing that achieves the Company's desired capital structure with an equity-to-total-capitalization ratio between 50% and 60%, inclusive of long-term and short-term debt. 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 timeThe liquidity provided by these sources is expected to time, we raise funds from the public debt and equity capital marketsbe sufficient to fund the Company's working capital needs and capital expenditure program for the remainder of fiscal year 2018 and beyond. Please refer to the TCJA Impact section above regarding anticipated impacts on our liquidity, needs.capital resources and cash flows.
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, in November 2017, we have filed a prospectus supplement for an at–the-marketat-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$500 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 June 30, 2017,2018, approximately $1.6 billion$650 million of securities remainremained available for issuance under the shelf registration statement.

Cash Flows
Our internally generated funds may change in the future due to a number of factors, some of which we cannot control. These factors 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 nine months ended June 30, 2017,2018, we generated cash flow of $745.6 million from operating activities of over $1.0 billion compared with $629.9$745.6 million for the nine months ended June 30, 2016.2017. The $115.6$289.7 million increase in operating cash flows reflects the positive cash effects of successful rate case outcomes achieved in fiscal 20162017 and changes in working capital, primarily as a result of the recoverytiming of deferred purchased gas costs.cost recoveries under our purchase gas cost mechanisms as a result of a period-over-period increase in sales volumes. This increase in sales volumes also contributed to the period-over-period increase in operating cash flow.
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 ofwe have incurred capital expenditures to support our cash resources has been used to fund our ongoing construction program, which enables us to enhance the safetydistribution and reliability of the systems used to provide natural gas distribution services to our existing customer base,transmission system modernization and integrity enhancement efforts, 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 nine months ended June 30, 2017,2018, cash used for investing activities was $1.1 billion compared to $747.4 million compared to $783.4 million infor the prior-year period.nine months ended June 30, 2017. Capital spending increased by $22.5$276.3 million, or 2.834 percent, as a result of planned increases in our distribution segment to repair and replace vintage pipe, partially offset by a decreaseand increases 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 itsour local distribution company customers. Cash flows from investing activitiesThe period-over-period increase also include proceedsreflects the absence in the current year period of $140.3 million in net proceeds received from the sale of AEM, a portion of the$18.6 million in proceeds received from the completion of athe State of Texas use tax audit and the $86.1 million used to purchase Enlinkacquire the North Texas Pipeline in the first fiscal quarter of 2017.December 2016.
Cash flows from financing activities
For the nine months ended June 30, 2017,2018, our financing activities generated $24.0provided $46.4 million of cash compared with $191.0$24.0 million generated in the prior-year period. The $167.0$22.4 million decreaseincrease in cash provided by financing activities is primarily due to the reduction in our short-term debt, partially offset byreflects an increase in cash used for investing activities that exceeded the increase in cash flows provided by operating activities during the nine months ended June 30, 2018.
In the nine months ended June 30, 2018, we used $395.1 million in net proceeds from equity financing to reduce short-term debt, to support our capital spending and for other general corporate purposes. Cash dividends increased due to a 7.8% increase in our dividend rate and an increase in shares outstanding.
In the nine months ended June 30, 2017, we issued $750 million of senior notes, as well as $125 million of long-term debt.


debt under our three year, $200 million term loan agreement and received $98.8 million in proceeds from the issuance of common stock under our ATM program. The net proceeds from these debt and equity issuances were used to reduce short and long-term debt, support our capital expenditures program and other general corporate purposes. Additionally, the return of cash collateral related to our forward-starting interest rate swaps due to an increase in interest rates provided cash from financing activities of $25.7 million. However, this was offset by the settlement of our forward starting interest rate swaps, which resulted in cash outflows of $37.0 million.
The following table summarizes our share issuances for the nine months ended June 30, 20172018 and 2016:2017:

The year-over-year decrease in the number of shares issued primarily reflects a decrease in shares issued under the Retirement Savings Plan and Trust and the 1998 Long-Term Incentive Plan.

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 and three committed revolving credit facilities with third-party lenders that provide a total of approximately $1.5 billion of working capital funding. As of June 30, 2017, the amount available to us under our credit facilities, net of commercial paper and outstanding letters of credit, was $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 two rating agencies: Standard & Poor’s Corporation (S&P) and Moody’s Investors Service (Moody’s). As of June 30, 2017,2018, both rating agencies maintained a stable outlook. Our current debt ratings are all considered investment grade and are as follows:
 S&P Moody’s
Senior unsecured long-term debtA  A2
Short-term debtA-1  P-1
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. The lowest investment grade credit rating is BBB- for S&P and Baa3 for 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 June 30, 2017.2018. 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 nine months ended June 30, 2017.2018.

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 profitcontribution margin through a combination of storage and financial instruments, including futures, over-the-counter and exchange-traded options and swap contracts with counterparties.

Pension and Postretirement Benefits Obligations
For the nine months ended June 30, 20172018 and 2016,2017, our total net periodic pension and other benefits costs were $34.7$31.2 million and $34.5$34.7 million. A substantial portionMost of thosethese costs relating to our natural gas distribution operations are recoverable through our gas distribution rates; however, atariff rates. 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 20172018 costs were determined using a September 30, 20162017 measurement date. As of September 30, 2016,2017, interest and corporate bond rates were lowerhigher than the rates as of September 30, 2015.2016. Therefore, we decreasedincreased the discount rate used to measure our fiscal 20172018 net periodic cost from 4.553.73 percent to 3.733.89 percent. We maintainedlowered the expected return on plan assets of 7.00to 6.75 percent in the determination of our fiscal 20172018 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 20172018 net periodic pension cost to be generally consistent withapproximately 25 percent lower than fiscal 2016.2017.
The amount with which we fundof funding required for 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, 2017,2018, we arewere not required to make a minimum contribution to our defined benefit plan during fiscal 2017.2018. However, in June 2017, we madewill consider whether a voluntary contribution of $5.0 million.is prudent to maintain certain funding levels.
For the nine months ended June 30, 20172018 we contributed $9.9$11.4 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.


2018.
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.
