SPIRE INC., SPIRE MISSOURI INC. AND SPIRE ALABAMA INC.

NOTES TO FINANCIAL STATEMENTS

(UNAUDITED)

(Dollars in millions, except per share amounts)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION – These notes are an integral part of the accompanying unaudited financial statements of Spire Inc. (“Spire” or the “Company”) presented on a consolidated basis, Spire Missouri Inc. (“Spire Missouri” or the “Missouri Utilities”) and Spire Alabama Inc. (“Spire Alabama”). Spire Missouri and Spire Alabama are wholly owned subsidiaries of Spire. Spire Missouri, Spire Alabama and the subsidiaries of Spire EnergySouth Inc. (“Spire EnergySouth”) are collectively referred to as the “Utilities.” The subsidiaries of Spire EnergySouth are Spire Gulf Inc. and Spire Mississippi Inc.

The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information with the instructions to Form 10-Q and Rule 10-01 of Regulation S‑X. Accordingly, they do not include all the disclosures required for complete financial statements. In the opinion of management, the accompanying unaudited financial statements include all adjustments (consisting of only normal recurring adjustments) necessary for the fair presentation of the results of operations for the periods presented. This Form 10-Q should be read in conjunction with the Notes to Financial Statements contained in Spire’s, Spire Missouri’s and Spire Alabama’s combined Annual Report on Form 10-K for the fiscal year ended September 30, 2019.

The consolidated financial position, results of operations, and cash flows of Spire include the accounts of the Company and all its subsidiaries. Transactions and balances between consolidated entities have been eliminated from the consolidated financial statements of Spire. In compliance with GAAP, transactions between Spire Missouri and Spire Alabama and their affiliates, as well as intercompany balances on their balance sheets, have not been eliminated from their separate financial statements.

NATURE OF OPERATIONS – Spire has two reportable segments: Gas Utility and Gas Marketing. The Gas Utility segment consists of the regulated natural gas distribution operations of the Company and is the core business segment of Spire in terms of revenue and earnings. The Gas Utility segment is comprised of the operations of: the Missouri Utilities, serving St. Louis and eastern Missouri (“Spire Missouri East”) and Kansas City and western Missouri (“Spire Missouri West”); Spire Alabama, serving central and northern Alabama; and the subsidiaries of Spire EnergySouth, serving southern Alabama and south-central Mississippi. The Gas Marketing segment includes Spire’s primary gas-related business, Spire Marketing Inc. (“Spire Marketing”), which provides non-regulated natural gas services, primarily in the central and southern United States (U.S.). The activities of other subsidiaries are reported as Other and are described in Note 10, Information by Operating Segment. Spire Missouri and Spire Alabama each have a single reportable segment.

Nearly all the Company’s earnings are derived from its Gas Utility segment. Due to the seasonal nature of the Utilities’ business and the Spire Missouri rate design, earnings are typically concentrated during the heating season of November through April each fiscal year. As a result, the interim statements of income for Spire, Spire Missouri and Spire Alabama are not necessarily indicative of annual results or representative of succeeding quarters of the fiscal year.

20

DERIVATIVES – In the course of their business, certain subsidiaries of Spire enter into commitments associated with the purchase or sale of natural gas. Certain of their derivative natural gas contracts are designated as normal purchases or normal sales and, as such, are excluded from the scope of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 815, Derivatives and Hedging. Those contracts are accounted for as executory contracts and recorded on an accrual basis. Revenues and expenses from such contracts are recorded gross. Contracts not designated as normal purchases or normal sales are recorded as derivatives with changes in fair value recognized in earnings in the periods prior to physical delivery. Certain of Spire Marketing’s wholesale purchase and sale transactions are classified as trading activities for financial reporting purposes. Under GAAP, revenues and expenses associated with trading activities are presented on a net basis in Gas Marketing operating revenues (or expenses, if negative) in the Condensed Consolidated Statements of Income. This net presentation has no effect on operating income or net income.

REGULATED OPERATIONS – The Utilities account for their regulated operations in accordance with FASB ASC Topic 980, Regulated Operations. This topic sets forth the application of GAAP for those companies whose rates are established by or are subject to approval by an independent third-party regulator. The provisions of this accounting guidance require, among other things, that financial statements of a regulated enterprise reflect the actions of regulators, where appropriate. These actions may result in the recognition of revenues and expenses in time periods that are different than non-regulated enterprises. When this occurs, costs are deferred as assets in the balance sheet (regulatory assets) and recorded as expenses when those amounts are reflected in rates. In addition, regulators can impose liabilities upon a regulated company for amounts previously collected from customers and for recovery of costs that are expected to be incurred in the future (regulatory liabilities). Management believes that the current regulatory environment supports the continued use of these regulatory accounting principles and that all regulatory assets and regulatory liabilities are recoverable or refundable through the regulatory process.

As authorized by the Missouri Public Service Commission (MoPSC), the Mississippi Public Service Commission (MSPSC) and the Alabama Public Service Commission (APSC), the Purchased Gas Adjustment (PGA) clauses and Gas Supply Adjustment (GSA) riders allow the Utilities to pass through to customers the cost of purchased gas supplies. Regulatory assets and liabilities related to the PGA clauses and the GSA riders are both labeled Unamortized Purchased Gas Adjustments herein. See additional information about regulatory assets and liabilities in Note 4, Regulatory Matters.

TRANSACTIONS WITH AFFILIATES – Transactions between affiliates of the Company have been eliminated from the consolidated financial statements of Spire. Spire Missouri and Spire Alabama borrowed funds from the Company and incurred related interest, as reflected in their separate financial statements, and they participated in normal intercompany shared services transactions. In addition, Spire Missouri’s other transactions with affiliates are presented in the table below:

	Three Months Ended December 31,
	2019		2018
Purchases of natural gas from Spire Marketing Inc.	$	19.5	$	39.8
Transportation services received from Spire STL Pipeline LLC		3.9		—
Sales of natural gas to Spire Marketing Inc.		—		1.4
Transportation services received from Spire NGL Inc.		0.3		0.3

In the quarter ended December 31, 2019, Spire Alabama had purchases of natural gas from Spire Marketing totaling $3.3.

ACCRUED CAPITAL EXPENDITURES – Accrued capital expenditures, shown in the following table, are excluded from capital expenditures in the statements of cash flows until paid.

	December 31,		September 30,		December 31,
	2019		2019		2018
Spire	$	45.8	$	80.6	$	46.2
Spire Missouri		20.2		40.1		18.1
Spire Alabama		9.8		11.9		9.7

NEW ACCOUNTING PRONOUNCEMENTS – Spire, Spire Missouri and Spire Alabama adopted Accounting Standards Update (ASU) No. 2016-02, Leases, along with related ASU Nos. 2018-01, 2018-10, 2018-11, 2018-20 and 2019-01 (collectively, “ASC 842”) using a modified retrospective transition method for leases existing at, or entered into after, October 1, 2019. Under the selected transition method, comparative periods in the financial statements are presented under ASC 840 (previous lease accounting guidance). ASC 842 requires lessees to recognize a right-of-use asset and lease liability for almost all lease contracts based on the present value of lease payments. It provides new guidelines for identifying and classifying a lease, and classification affects the pattern and income statement line item for the related expense. The Company and its subsidiaries elected a package of three practical expedients permitted by the standard, allowing them not to reassess existing contracts for (1) whether it is or contains a lease, (2) lease classification and (3) initial direct costs. They also elected to use the benefit of hindsight in determining both the lease term and impairments associated with any existing leases, which resulted in lease terms that best represent management’s expectations with respect to use of the underlying asset but did not result in recognition of any impairment. Finally, they elected not to assess whether existing land easements are leases under ASC 842. The adoption of ASC 842 impacted the balance sheets through recognition of right-of-use assets and lease liabilities for operating leases but did not result in a cumulative effect adjustment or significant impacts to income or cash flows. For other lease policy elections and disclosures about leases, see Note 12, Leases.

Spire, Spire Missouri and Spire Alabama adopted the guidance in ASU No. 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities, and related ASU Nos. 2018-16, 2019-04, and 2019-10 in the first quarter of fiscal year 2020. The amendments in this ASU more closely align the results of hedge accounting with risk management activities through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results in the financial statements. They did not have a significant impact on the financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments, which was later supplemented by ASU Nos. 2018-19, 2019-04, 2019-05 and 2019-11. The standard introduces new guidance for the accounting for credit losses on instruments within its scope, including trade receivables. It is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The new guidance will be initially applied through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. Spire, Spire Missouri and Spire Alabama are currently assessing the impacts of adopting this standard, which must be adopted by the first quarter of fiscal 2021.

A portion of the Company’s and Spire Missouri’s regulatory assets are not earning a return, as shown in the table below:

	December 31,		September 30,		December 31,
	2019		2019		2018
Spire
Pension and postretirement benefit costs	$	208.0	$	211.1	$	141.2
Future income taxes due from customers		111.6		108.8		99.1
Other		14.1		14.3		14.3
Total Regulatory Assets Not Earning a Return	$	333.7	$	334.2	$	254.6
Spire Missouri
Pension and postretirement benefit costs	$	208.0	$	211.1	$	141.2

Other		14.1		14.3		14.3
Total Regulatory Assets Not Earning a Return	$	327.0	$	328.3	$	252.2

Like all the Company’s regulatory assets, these regulatory assets are expected to be recovered from customers in future rates. The recovery period for the future income taxes due from customers and pension and other postretirement benefit costs could be 20 years or longer, based on current Internal Revenue Service guidelines and average remaining service life of active participants, respectively. The other items not earning a return are expected to be recovered over a period not to exceed 15 years, consistent with precedent set by the MoPSC. Spire Alabama does not have any regulatory assets that are not earning a return.

On March 7, 2018, the MoPSC issued its order in two general rate cases (docketed as GR-2017-0215 and GR-2017-0216), approving new tariffs that became effective on April 19, 2018. Certain provisions of the order allow less future recovery of certain deferred or capitalized costs than estimated based upon previous rate proceedings, and management determined that the related regulatory assets should be written down or off in connection with the preparation of the financial statements for the second quarter of 2018. The charges totaled $38.4 for the year ended September 30, 2018 and are included primarily in operation and maintenance expense on the statements of income and in other cash flows from operating activities on the statements of cash flows. The after-tax reduction to net income and earnings per share was $23.6 and $0.49, respectively. On April 25, 2018, Spire Missouri filed an appeal of the MoPSC’s order related to the disallowance of certain pension costs incurred prior to 1997 ($28.8), real estate sold in 2014 ($1.8), and rate case expenses ($0.9) to Missouri’s Southern District Court of Appeals. On March 15, 2019, the appeal was denied by the Southern District Court of Appeals, and Spire Missouri requested review by the Missouri Supreme Court, which agreed to take the case. Oral arguments were made before the Missouri Supreme Court on January 29, 2020. The charges related to the long-standing pension and real estate assets, totaling $30.6, were excluded in the determination of 2018 net economic earnings.

Spire Missouri filed Infrastructure System Replacement Surcharge (ISRS) applications which were approved by the MoPSC and the costs associated therewith were included in new tariffs that went into effect from our last general rate cases on April 19, 2018.  Since the Company’s last rate cases, ISRS filings became effective on October 8, 2018, May 25, 2019 and November 16, 2019, bringing total authorized future annualized ISRS revenues for Spire Missouri to $29.2. On February 3, 2020, Spire Missouri filed new ISRS applications with the MoPSC for a total of $16.3, including $5.3 of ISRS revenues previously disallowed.

As reported last year, on November 19, 2019, the Missouri Western District Court of Appeals issued rulings (“ISRS rulings”) that determined certain capital investments in 2016 through 2018 were not eligible for recovery under the ISRS. The ISRS rulings upheld appeals by the Office of Public Counsel (OPC) that contested recovery of portions of Spire Missouri’s ISRS and overturned the three prior MoPSC decisions.

27

Spire Missouri strongly disagrees with the ISRS rulings and plans to vigorously defend its position. On January 2, 2020, Spire Missouri submitted Applications for Transfer to the Missouri Supreme Court. The MoPSC also submitted Applications for Transfer to the Missouri Supreme Court that advanced similar positions as Spire Missouri. The submission of the Applications will stay the effectiveness of the ISRS rulings pending the outcome of the Missouri Supreme Court’s decision whether to accept these rulings for review. If the Missouri Supreme Court decides not to review the lower court rulings, the cases would be remanded to the MoPSC, who would then define its process to review the facts and evidence supporting its earlier approval and determine the appropriate process to determine the appropriate refund, if any, that may be required.

Spire Missouri has recorded an estimate of the maximum impact of the ISRS rulings based on its interpretation of the rulings and evidence available. As of September 30, 2019, Spire Missouri recorded an estimated $12.2 regulatory liability for this matter by reducing revenue for fiscal year 2019. There were two components of this provision. The first related to a $4.2 refund ordered by the ISRS rulings for amounts collected prior to the last rate case, after which recoveries of related authorized revenues became part of base rates that went into effect in April 2018. The second component related to an estimate of $8.0 for revenues associated with the June 2018 ISRS filing that was approved by the MoPSC effective October 8, 2018. In the first quarter of fiscal 2020, an additional provision of $2.1 was recorded to the regulatory liability for ISRS revenues related to customer billings recorded during the quarter under this 2018 filing, along with a $0.5 provision for interest due on the entirety of the ISRS revenues in dispute if refunded. The after-tax impact of the first quarter provisions reduced net income by $2.0, which is excluded for the net economic earnings financial measure. In future periods, Spire Missouri will evaluate the need for an adjustment to the provisions based upon new information and further developments.

Similar appeals by both the Company and OPC are with the Missouri Western District Court of Appeals for the ISRS filings in both January 2019 and July 2019.

In January 2020, legislation was introduced in both the Missouri House and Senate to clarify language in the statute governing ISRS mechanism.  Specifically, the bills seek to ensure we can continue to upgrade our infrastructure, enhance its safety and reliability, and secure timely recovery of costs incurred.

As part of their annual updates for RSE, on November 25, 2019, Spire Alabama and Spire Gulf filed an increase for rate year 2020 of $5.9 and $1.6, respectively, which became effective December 1, 2019. In addition, Spire Alabama was granted authority to begin an off-system sales and capacity release sharing program similar to the program currently in place at Spire Missouri.

On November 21, 2019, the Federal Energy Regulatory Commission (FERC) issued an Order on Rehearing of its August 3, 2018 order issuing a certificate of public convenience and necessity to Spire STL Pipeline LLC. In the Order on Rehearing, the FERC dismissed or denied the outstanding requests for rehearing filed by several parties, dismissed the request for stay filed by one party and noted the withdrawal of the request for rehearing by another party. On January 21, 2020, two of the rehearing parties timely filed petitions for review of the FERC’s orders with the Court of Appeals for the District of Columbia Circuit.

5. FINANCING ARRANGEMENTS AND LONG-TERM DEBT

Spire, Spire Missouri and Spire Alabama have a syndicated revolving credit facility pursuant to a loan agreement with 11 banks, expiring October 31, 2023. The loan agreement has an aggregate credit commitment of $975.0, including sublimits of $300.0 for Spire, $475.0 for Spire Missouri, and $200.0 for Spire Alabama. These sublimits may be reallocated from time to time among the three borrowers within the $975.0 aggregate commitment, with commitments fees applied for each borrower relative to its credit rating. Spire may use its line to provide for the funding needs of various subsidiaries. The agreement also contains financial covenants limiting each borrower’s consolidated total debt, including short-term debt, to no more than 70% of its total capitalization. As defined in the line of credit, on December 31, 2019, total debt was 55% of total capitalization for the consolidated Company, 50% for Spire Missouri, and 41% for Spire Alabama. There were no borrowings against this credit facility as of December 31, 2019, September 30, 2019, or December 31, 2018.

28

Spire has a commercial paper program (“CP Program”) pursuant to which Spire may issue short-term, unsecured commercial paper notes. Amounts available under the CP Program may be borrowed, repaid and re-borrowed from time to time, with the aggregate face or principal amount of the notes outstanding under the CP Program at any time not to exceed $975.0. The notes may have maturities of up to 365 days from date of issue.

Information about Spire’s consolidated short-term borrowings and about Spire Missouri’s and Spire Alabama’s borrowings from Spire is presented in the following table. As of December 31, 2019, $373.2 of Spire’s short-term borrowings were used to support lending to the Utilities.

6. FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amounts and estimated fair values of financial instruments not measured at fair value on a recurring basis are shown in the following tables, classified according to the fair value hierarchy. There were no such instruments classified as Level 3 (significant unobservable inputs) as of December 31, 2019, September 30, 2019, or December 31, 2018.

The carrying amounts of cash and cash equivalents and short-term debt approximate fair value due to the short maturity of these instruments. The fair values of long-term debt are estimated based on market prices for similar issues. Refer to Note 7, Fair Value Measurements, for information on financial instruments measured at fair value on a recurring basis.

7. FAIR VALUE MEASUREMENTS

The information presented below categorizes the assets and liabilities in the balance sheets that are accounted for at fair value on a recurring basis in periods subsequent to initial recognition.

The mutual funds included in Level 1 are valued based on exchange-quoted market prices of individual securities.

Derivative instruments included in Level 1 are valued using quoted market prices on the New York Mercantile Exchange (NYMEX) or the Intercontinental Exchange (ICE). Derivative instruments classified in Level 2 include physical commodity derivatives that are valued using broker or dealer quotation services whose prices are derived principally from, or are corroborated by, observable market inputs. Also included in Level 2 are certain derivative instruments that have values that are similar to, and correlate with, quoted prices for exchange-traded instruments in active markets. Derivative instruments included in Level 3 are valued using generally unobservable inputs that are based upon the best information available and reflect management’s assumptions about how market participants would price the asset or liability. The Level 3 balances as of December 31, 2019, September 30, 2019, and December 31, 2018, consisted of gas commodity contracts. The Company’s and the Utilities’ policy is to recognize transfers between the levels of the fair value hierarchy, if any, as of the beginning of the interim reporting period in which circumstances change or events occur to cause the transfer.

The mutual funds are included in “Other Investments” on the Company’s balance sheets and in “Other Property and Investments” on Spire Missouri’s balance sheets. Derivative assets and liabilities, including receivables and payables associated with cash margin requirements, are presented net in the balance sheets when a legally enforceable netting agreement exists between the Company, Spire Missouri, or Spire Alabama and the counterparty to a derivative contract.

8. CONCENTRATIONS OF CREDIT RISK

Spire’s Gas Utility segment serves 1.7 million customers in three states across multiple rate classes resulting in a significant amount of revenue diversity. Credit risk is mitigated by the high percentage of residential customers as well as the geographic diversity of the Utilities, though customers for each Utility are concentrated in a single state.

A significant portion of Spire Marketing’s transactions are with (or are associated with) energy producers, utility companies, and pipelines. The concentration of transactions with these counterparties has the potential to affect the Company’s overall exposure to credit risk, either positively or negatively, in that each of these three groups may be affected similarly by changes in economic, industry, or other conditions. To manage this risk, as well as credit risk from significant counterparties in these and other industries, Spire Marketing has established procedures to determine the creditworthiness of its counterparties. These procedures include obtaining credit ratings and credit reports, analyzing counterparty financial statements to assess financial condition, and considering the industry environment in which the counterparty operates. This information is monitored on an ongoing basis. In some instances, Spire Marketing may require credit assurances such as prepayments, letters of credit, or parental guaranties. In addition, Spire Marketing may enter into netting arrangements to mitigate credit risk with counterparties in the energy industry with whom it conducts both sales and purchases of natural gas. Sales are typically made on an unsecured credit basis with payment due the month following delivery. Accounts receivable amounts are closely monitored and provisions for uncollectible amounts are accrued when losses are probable. Spire Marketing records accounts receivable, accounts payable, and prepayments for physical sales and purchases of natural gas on a gross basis. The amount included in its accounts receivable attributable to energy producers and their marketing affiliates totaled $20.9 at December 31, 2019 ($11.7 reflecting netting arrangements). Spire Marketing’s accounts receivable attributable to utility companies and their marketing affiliates totaled $84.2 at December 31, 2019 ($75.4 reflecting netting arrangements).

Spire Marketing also has concentrations of credit risk with pipeline companies associated with its natural gas receivable and with certain individually significant counterparties. At December 31, 2019, the amounts included in accounts receivable from its five largest counterparties (in terms of net accounts receivable exposure) totaled $33.6 ($30.7 reflecting netting arrangements). Of these five counterparties, two are investment-grade rated utilities. Of the three that are not rated, one has its outstanding credit guaranteed by a creditworthy subsidiary of an investment-grade rated company, another is not rated but each of its owners is investment-grade, and the third has its outstanding credit supported by a parental guaranty.

9. PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

Pension Plans

Spire and the Utilities maintain pension plans for their employees.

The Missouri Utilities have non-contributory, defined benefit, trusteed forms of pension plans covering the majority of their employees. Plan assets consist primarily of corporate and U.S. government obligations and a growth segment consisting of exposure to equity markets, commodities, real estate and inflation-indexed securities, achieved through derivative instruments.

Spire Alabama has non-contributory, defined benefit, trusteed forms of pension plans covering the majority of its employees. Qualified plan assets are comprised of mutual and commingled funds consisting of U.S. equities with varying strategies, global equities, alternative investments, and fixed income investments.

Net pension cost	$	2.9		$	2.7

* Denotes pension expense line items that are recorded below the operating income line in the income statements, in the line item “Other Income (Expense), Net.”

Pursuant to the provisions of the Missouri Utilities’ and Spire Alabama’s pension plans, pension obligations may be satisfied by monthly annuities, lump-sum cash payments, or special termination benefits. Lump-sum payments are recognized as settlements (which can result in gains or losses) only if the total of such payments exceeds the sum of service and interest costs in a specific year. Special termination benefits, when offered, are also recognized as settlements which can result in gains or losses. For the first quarter of both fiscal 2020 and fiscal 2019, no pension plans met the criteria for settlement recognition.      

The funding policy of the Utilities is to contribute an amount not less than the minimum required by government funding standards, nor more than the maximum deductible amount for federal income tax purposes. Fiscal 2020 contributions to Spire Missouri’s pension plans through December 31, 2019 were $4.1 to the qualified trusts and none to non-qualified plans. There were $1.6 of fiscal 2020 contributions to the Spire Alabama pension plans through December 31, 2019.

Contributions to the qualified trusts of the Missouri Utilities’ pension plans for the remainder of fiscal 2020 are anticipated to be $24.9. Contributions to Spire Alabama’s pension plans are expected to be $11.5 for the remainder of fiscal 2020.

35

Other Postretirement Benefits

Spire and the Utilities provide certain life insurance benefits at retirement. Spire Missouri plans provide for medical insurance after early retirement until age 65. For retirements prior to January 1, 2015, the Spire Missouri West plans provided medical insurance after retirement until death. The Spire Alabama plans provide medical insurance upon retirement until death for certain retirees depending on the type of employee and the date the employee was originally hired.

Net periodic postretirement benefit costs consisted of the following components:

* Denotes other postretirement expense line items that are recorded below the operating income line in the income statements, in the line item “Other Income (Expense), Net.”

Missouri and Alabama state laws provide for the recovery in rates of costs accrued pursuant to GAAP provided that such costs are funded through an independent, external funding mechanism. The Utilities have established Voluntary Employees’ Beneficiary Association (VEBA) and Rabbi Trusts as external funding mechanisms. The assets of the VEBA and Rabbi Trusts consist primarily of money market securities and mutual funds invested in stocks and bonds.

The Utilities’ funding policy is to contribute amounts to the trusts equal to the periodic benefit cost calculated pursuant to GAAP as recovered in rates. There have been no contributions to the postretirement plans through December 31, 2019 for the Missouri Utilities or Spire Alabama, and none are expected to be required for the remainder of the fiscal year.

10. INFORMATION BY OPERATING SEGMENT

The Company has two reportable segments: Gas Utility and Gas Marketing. The Gas Utility segment is the aggregation of the operations of the Utilities. The Gas Marketing segment includes the results of Spire Marketing, a subsidiary engaged in the non-regulated marketing of natural gas and related activities, including utilizing natural gas storage contracts for providing natural gas sales. Other components of the Company’s consolidated information include:

• unallocated corporate items, including certain debt and associated interest costs;

• Spire STL Pipeline, a subsidiary of Spire which has constructed and, as of November 2019, operates a 65-mile FERC-regulated pipeline to deliver natural gas into eastern Missouri;

• Spire Storage, a subsidiary of Spire providing physical natural gas storage services; and

• Spire’s subsidiaries engaged in the operation of a propane pipeline, the compression of natural gas, and risk management, among other activities.

Accounting policies are described in Note 1, Summary of Significant Accounting Policies. Intersegment transactions include sales of natural gas from Spire Marketing to Spire Missouri and Spire Alabama, sales of natural gas from Spire Missouri to Spire Marketing, propane transportation services provided by Spire NGL Inc. to Spire Missouri, and propane storage services provided by Spire Missouri to Spire NGL Inc.

Management evaluates the performance of the operating segments based on the computation of net economic earnings. Net economic earnings exclude from reported net income the after-tax impacts of fair value accounting and timing adjustments associated with energy-related transactions, the impacts of acquisition, divestiture and restructuring activities, and the largely non-cash impacts of other non-recurring or unusual items such as certain regulatory, legislative, or GAAP standard-setting actions. In fiscal 2020, this includes provisions for the ISRS rulings discussed in Note 4, Regulatory Matters.

11. COMMITMENTS AND CONTINGENCIES

Commitments

The Company and the Utilities have entered into contracts with various counterparties, expiring on dates through 2032, for the storage, transportation, and supply of natural gas. Minimum payments required under the contracts in place at December 31, 2019, are estimated at $1,554.6, $690.3, and $239.3 for the Company, Spire Missouri, and Spire Alabama, respectively. Additional contracts are generally entered into prior to or during the heating season of November through April. The Utilities recover their costs from customers in accordance with their PGA clauses or GSA riders.

38

Contingencies

The Company and the Utilities account for contingencies, including environmental liabilities, in accordance with accounting standards under the loss contingency guidance of ASC Topic 450, Contingencies, when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

In addition to matters noted below, the Company and the Utilities are involved in other litigation, claims, and investigations arising in the normal course of business. Management, after discussion with counsel, believes the final outcome will not have a material effect on the statements of income, balance sheets, and statements of cash flows of the Company, Spire Missouri, or Spire Alabama. However, there is uncertainty in the valuation of pending claims and prediction of litigation results.

The Company and the Utilities own and operate natural gas distribution, transmission, and storage facilities, the operations of which are subject to various environmental laws, regulations, and interpretations. While environmental issues resulting from such operations arise in the ordinary course of business, such issues have not materially affected the Company’s or Utilities’ financial position and results of operations. As environmental laws, regulations, and their interpretations change, the Company or the Utilities may incur additional environmental liabilities that may result in additional costs, which may be material.

In the natural gas industry, many gas distribution companies have incurred environmental liabilities associated with sites they or their predecessor companies formerly owned or operated where manufactured gas operations took place. The Utilities each have former manufactured gas plant (MGP) operations in their respective service territories. To the extent costs are incurred associated with environmental remediation activities, the Utilities would request authority from their respective regulators to defer such costs (less any amounts received from insurance proceeds or as contributions from other potentially responsible parties (PRPs)) and collect them through future rates.

Spire Missouri

Spire Missouri has identified three former MGP sites in the city of St. Louis, Missouri (the “City”) where costs have been incurred and claims have been asserted. Spire Missouri has enrolled two of the sites in the Missouri Department of Natural Resources (MDNR) Brownfields/Voluntary Cleanup Program (BVCP). The third site is the result of a relatively new claim assertion by the United States Environmental Protection Agency (EPA).

In conjunction with redevelopment of one of the sites, Spire Missouri and another former owner of the site entered into an agreement (the “Remediation Agreement”) with the City development agencies, the developer, and an environmental consultant that obligates one of the City agencies and the environmental consultant to remediate the site and obtain a No Further Action letter from the MDNR. The Remediation Agreement also provides for a release of Spire Missouri and the other former site owner from certain liabilities related to the past and current environmental condition of the site and requires the developer and the environmental consultant to maintain certain insurance coverage, including remediation cost containment, premises pollution liability, and professional liability. The operative provisions of the Remediation Agreement were triggered on December 20, 2010, on which date Spire Missouri and the other former site owner, as full consideration under the Remediation Agreement, paid a small percentage of the cost of remediation of the site. The amount paid by Spire Missouri did not materially impact the financial condition, results of operations, or cash flows of the Company.

Spire Missouri has not owned the second site for many years. In a letter dated June 29, 2011, the Attorney General for the State of Missouri informed Spire Missouri that the MDNR had completed an investigation of the site. The Attorney General requested that Spire Missouri participate in the follow up investigations of the site. In a letter dated January 10, 2012, Spire Missouri stated that it would participate in future environmental response activities at the site in conjunction with other PRPs that are willing to contribute to such efforts in a meaningful and equitable fashion. Accordingly, Spire Missouri entered into a cost sharing agreement for remedial investigation with other PRPs. To date, MDNR has not approved the agreement, so remedial investigation has not yet occurred.

39

Additionally, in correspondence dated November 30, 2016, Region 7 of the EPA has asserted that Spire Missouri is liable under Section 107(a) of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) for alleged coal gas waste contamination at a third site in the northern portion of the City on which Spire Missouri operated a MGP. Spire Missouri has not owned or operated the site (also known as Station “B”) for over 70 years. Spire Missouri and the site owner have met with the EPA and reviewed its assertions. Both Spire Missouri and the site owner have notified the EPA that information and data provided by the EPA to date does not rise to the level of documenting a threat to the public health or environment. As such, Spire Missouri requested more information from the EPA, some of which would also be utilized to identify other former owners and operators of the site that could be added as PRPs. To date, Spire Missouri has not received a response from the EPA.

Spire Missouri has notified its insurers that it seeks reimbursement for costs incurred in the past and future potential liabilities associated with these MGP sites. While some of the insurers have denied coverage and reserved their rights, Spire Missouri retains the right to seek potential reimbursements from them.

On March 10, 2015, Spire Missouri received a Section 104(e) information request under CERCLA from EPA Region 7 regarding the former Thompson Chemical/Superior Solvents site in the City. In turn, Spire Missouri issued a Freedom of Information Act (FOIA) request to the EPA on April 3, 2015, in an effort to identify the basis of the inquiry. The FOIA response from the EPA was received on July 15, 2015 and a response was provided to the EPA on August 15, 2015. Spire Missouri has received no further inquiry from the EPA regarding this matter.

In its western service area, Spire Missouri has seven owned MGP sites enrolled in the BVCP, including Joplin MGP #1, St. Joseph MGP #1, Kansas City Coal Gas Station B, Kansas City Station A Railroad area, Kansas City Coal Gas Station A North, Kansas City Coal Gas Station A South, and Independence MGP #2. Source removal has been conducted at all of the owned sites since 2003 with the exception of Joplin. On September 15, 2016, a request was made with the MDNR for a restrictive covenant use limitation with respect to Joplin. Remediation efforts at the seven sites are at various stages of completion, ranging from groundwater monitoring and sampling following source removal activities to the aforementioned request in respect to Joplin. As part of its participation in the BVCP, Spire Missouri communicates regularly with the MDNR with respect to its remediation efforts and monitoring activities at these sites. On May 11, 2015, MDNR approved the next phase of investigation at the Kansas City Station A North and Railroad areas.

To date, costs incurred for all Missouri Utilities’ MGP sites for investigation, remediation and monitoring these sites have not been material. However, the amount of costs relative to future remedial actions at these and other sites is unknown and may be material. The actual future costs that Spire Missouri may incur could be materially higher or lower depending upon several factors, including whether remediation actions will be required, final selection and regulatory approval of any remedial actions, changing technologies and government regulations, the ultimate ability of other PRPs to pay, and any insurance recoveries.

In 2013, Spire Missouri retained an outside consultant to conduct probabilistic cost modeling of 19 former MGP sites owned or operated by Spire Missouri. The purpose of this analysis was to develop an estimated range of probabilistic future liability for each site. That analysis, completed in August 2014, provided a range of demonstrated possible future expenditures to investigate, monitor and remediate all 19 MGP sites. Spire Missouri has recorded its best estimate of the probable expenditures that relate to these matters. The amount is not material.

Spire Missouri and the Company do not expect potential liabilities that may arise from remediating these sites to have a material impact on their future financial condition or results of operations.

Spire Alabama

Spire Alabama is in the chain of title of nine former MGP sites, four of which it still owns, and five former manufactured gas distribution sites, one of which it still owns. Spire Alabama does not foresee a probable or reasonably estimable loss associated with these sites. Spire Alabama and the Company do not expect potential liabilities that may arise from remediating these sites to have a material impact on their future financial condition or results of operations.

40

In 2012, Spire Alabama responded to an EPA Request for Information Pursuant to Section 104 of CERCLA relating to the 35th Avenue Superfund Site located in North Birmingham, Jefferson County, Alabama. Spire Alabama was identified as a PRP under CERCLA for the cleanup of the site or costs the EPA incurs in cleaning up the site. At this point, Spire Alabama has not been provided information that would allow it to determine the extent, if any, of its potential liability with respect to the 35th Avenue Superfund Site and vigorously denies its inclusion as a PRP.

Spire

In addition to those discussed above for Spire Missouri and Spire Alabama, Spire is aware of the following contingent matter.

In February 2018, the Company was made aware of a complaint filed with the U.S. Department of Housing and Urban Development (HUD) by the South Alabama Center for Fair Housing and the National Community Reinvestment Coalition. The complaint alleges that the Company discriminated against unspecified residents of Eight Mile, Alabama, on the basis of race in violation of the Fair Housing Act by failing to adequately address the odorant release that occurred in 2008. The Company believes there is no basis for the complaint, HUD has no jurisdiction in the matter, and there will be no material impact on its future financial condition or results of operations.

12. LEASES

The lease agreement covering the Company’s primary office space in St. Louis extends through February 2035, with an option to renew for an additional five years. Spire Alabama currently has leased office space in two buildings in Birmingham; one lease expires in 2020 and the other extends through January 2024. The lease agreement covering Spire Marketing and Spire Storage office space in Houston extends through December 2028, with options to terminate three years earlier or to renew for an additional five years. The St. Louis and Houston renewals are reasonably certain and are included in the lease term used to determine the right-of use assets and lease liabilities. The Company and its subsidiaries have other relatively minor rental arrangements for real estate and equipment with remaining terms of up to eleven years.

Operating lease cost, cash flow and noncash information for the three months ended December 31, 2019 are shown in the following table.

	Spire		Spire Missouri		Spire Alabama
Operating lease cost, including amounts capitalized	$	2.4	$	0.2	$	1.0

Less present value discount		(27.4	)		(0.2	)		(0.4	)
Total current and noncurrent lease liabilities	$	69.1		$	1.9		$	8.7

As of September 30, 2019, the annual minimum rental commitments for operating leases (under ASC 840) were as follows.

	2020		2021		2022		2023		2024		Later		Total
Spire	$	8.2	$	7.0	$	6.8	$	6.1	$	4.8	$	36.5	$	69.4
Spire Missouri		0.5		0.2		—		—		—		—		0.7
Spire Alabama		2.9		2.1		2.1		2.1		0.7		—		9.9

There are no significant finance leases, short-term leases, subleases, variable lease payments, residual value guarantees, restrictions or covenants pertaining to leases.

The Company elected, for all asset classes, not to recognize right-of-use assets and lease liabilities for short-term leases. Instead, the lease payments are recognized in profit or loss on a straight-line basis over the lease term and variable lease payments are recognized in the period in which the obligation for those payments is incurred. The Company elected, for all asset classes, not to separate nonlease components from lease components and instead to account for each separate lease component and the nonlease components associated with that lease component as a single lease component.

The discount rate used for all the leases is the applicable incremental borrowing rate, which is the rate of interest that a lessee would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. For a subsidiary lessee, the rate applicable to the subsidiary is used unless the lease terms are influenced by parent credit.

• Employee workforce issues, including but not limited to labor disputes, the inability to attract and retain key talent, and future wage and employee benefit costs, including costs resulting from changes in discount rates and returns on benefit plan assets.

Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the Company’s Condensed Consolidated Financial Statements, Spire Missouri’s and Spire Alabama’s Condensed Financial Statements, and the notes thereto.

OVERVIEW

The Company has two reportable segments: Gas Utility and Gas Marketing. Nearly all of Spire’s earnings are derived from its Gas Utility segment, which reflects the regulated activities of the Utilities. Due to the seasonal nature of the Utilities’ business and the Spire Missouri rate design, earnings of Spire and each of the Utilities are typically concentrated during the heating season of November through April each fiscal year.

Gas Utility - Spire Missouri

Spire Missouri is Missouri’s largest natural gas distribution utility and is regulated by the MoPSC. Spire Missouri serves St. Louis and eastern Missouri through Spire Missouri East and serves Kansas City and western Missouri through Spire Missouri West. Spire Missouri purchases natural gas in the wholesale market from producers and marketers and ships the gas through interstate pipelines into its own distribution facilities for sale to residential, commercial and industrial customers. Spire Missouri also transports gas through its distribution system for certain larger customers who buy their own gas on the wholesale market. Spire Missouri delivers natural gas to customers at rates and in accordance with tariffs authorized by the MoPSC. The earnings of Spire Missouri are primarily generated by the sale of heating energy. The rate design for each service territory serves to lessen the impact of weather volatility on its customers during cold winters and stabilize Spire Missouri’s earnings.

Gas Utility - Spire Alabama

Spire Alabama is the largest natural gas distribution utility in the state of Alabama and is regulated by the APSC. Spire Alabama’s service territory is located in central and northern Alabama. Among the cities served by Spire Alabama are Birmingham, the center of the largest metropolitan area in the state, and Montgomery, the state capital. Spire Alabama purchases natural gas through interstate and intrastate suppliers and distributes the purchased gas through its distribution facilities for sale to residential, commercial and industrial customers, and other end-users of natural gas. Spire Alabama also provides transportation services to large industrial and commercial customers located on its distribution system. These transportation customers, using Spire Alabama as their agent or acting on their own, purchase gas directly from marketers or suppliers and arrange for delivery of the gas into the Spire Alabama distribution system. Spire Alabama charges a fee to transport such customer-owned gas through its distribution system to the customers’ facilities.

Gas Utility - Spire EnergySouth

Spire Gulf and Spire Mississippi are utilities engaged in the purchase, retail distribution and sale of natural gas to approximately 100,000 customers in southern Alabama and south-central Mississippi. Spire Gulf is regulated by the APSC, and Spire Mississippi is regulated by the MSPSC.

44

Gas Marketing

Spire Marketing is engaged in the marketing of natural gas and related activities on a non-regulated basis and is reported in the Gas Marketing segment. Spire Marketing markets natural gas across the central and southern U.S. It holds firm transportation and storage contracts in order to effectively manage its transactions with counterparties, which primarily include producers, municipalities, electric and gas utility companies, and large commercial and industrial customers.

Other

Other components of the Company’s consolidated information include:

• unallocated corporate items, including certain debt and associated interest costs;

• Spire STL Pipeline LLC (“Spire STL Pipeline”) and Spire Storage West LLC (“Spire Storage”), described below; and

• Spire’s subsidiaries engaged in the operation of a propane pipeline, the compression of natural gas, and risk management, among other activities.

Spire STL Pipeline is a wholly owned subsidiary of Spire which owns and operates a 65-mile pipeline connecting the Rockies Express Pipeline in Scott County, Illinois, to delivery points in St. Louis County, Missouri, including Spire Missouri’s storage facility. The pipeline is under the jurisdiction of the Federal Energy Regulatory Commission (FERC) and is capable of delivering up to 4 million therms per day of natural gas into eastern Missouri. Spire Missouri is the foundation shipper with a contractual commitment of 3.5 million therms per day. The pipeline was primarily constructed during fiscal 2019. In November 2019, Spire STL Pipeline received final authorization from the FERC and placed the pipeline into service.

Spire Storage is engaged in the storage of natural gas in the Western region of the United States. The facility consists of two storage fields operating under one FERC market-based rate tariff. We continue to analyze the fields’ capacity and injection/withdrawal capabilities as we invest to ensure reliable operations for this winter and improve profitability. Future development of Spire Storage would entail additional investments to increase injection, withdrawal and storage capacity and enhance connectivity within the facilities and with interconnected interstate pipelines.

NON-GAAP MEASURES

Net income, earnings per share and operating income reported by Spire, Spire Missouri and Spire Alabama are determined in accordance with accounting principles generally accepted in the United States of America (GAAP). Spire, Spire Missouri and Spire Alabama also provide the non-GAAP financial measures of net economic earnings, net economic earnings per share and contribution margin. Management and the Board of Directors use non-GAAP financial measures, in addition to GAAP financial measures, to understand and compare operating results across accounting periods, for financial and operational decision making, for planning and forecasting, to determine incentive compensation and to evaluate financial performance. These non-GAAP operating metrics should not be considered as alternatives to, or more meaningful than, the related GAAP measures. Reconciliations of non-GAAP financial measures to the most directly comparable GAAP measures are provided on the following pages.

45

Net Economic Earnings and Net Economic Earnings Per Share

Net economic earnings and net economic earnings per share are non-GAAP measures that exclude from net income the impacts of fair value accounting and timing adjustments associated with energy-related transactions, the impacts of acquisition, divestiture and restructuring activities, and the largely non-cash impacts of other non-recurring or unusual items such as certain regulatory, legislative or GAAP standard-setting actions. In the quarter ended December 31, 2019, this included a provision for refunds to customers of amounts collected under MoPSC-approved orders as a result of the November 2019 Infrastructure System Replacement Surcharge (ISRS) rulings discussed in Note 4, Regulatory Matters, of the Notes to Financial Statements in Item 1. In addition, net economic earnings per share excludes the impact, in the fiscal year of issuance, of shares issued to finance acquisitions that have yet to be included in net economic earnings.

The fair value and timing adjustments are made in instances where the accounting treatment differs from what management considers the economic substance of the underlying transaction, including the following:

• Net unrealized gains and losses on energy-related derivatives that are required by GAAP fair value accounting associated with current changes in the fair value of financial and physical transactions prior to their completion and settlement. These unrealized gains and losses result primarily from two sources:

1) changes in the fair values of physical and/or financial derivatives prior to the period of settlement; and

2) ineffective portions of accounting hedges, required to be recorded in earnings prior to settlement, due to differences in commodity price changes between the locations of the forecasted physical purchase or sale transactions and the locations of the underlying hedge instruments;

• Lower of cost or market adjustments to the carrying value of commodity inventories resulting when the net realizable value of the commodity falls below its original cost, to the extent that those commodities are economically hedged; and

• Realized gains and losses resulting from the settlement of economic hedges prior to the sale of the physical commodity.

These adjustments eliminate the impact of timing differences and the impact of current changes in the fair value of financial and physical transactions prior to their completion and settlement. Unrealized gains or losses are recorded in each period until being replaced with the actual gains or losses realized when the associated physical transactions occur. Management believes that excluding the earnings volatility caused by recognizing changes in fair value prior to settlement and other timing differences associated with related purchase and sale transactions provides a useful representation of the economic effects of only the actual settled transactions and their effects on results of operations. While management uses these non-GAAP measures to evaluate both Spire’s Utilities and its other gas-related businesses, the net effect of these fair value and timing adjustments on the Utilities’ earnings is minimal because gains or losses on their natural gas derivative instruments are deferred pursuant to state regulation.

Contribution Margin

In addition to operating revenues and operating expenses, management also uses the non-GAAP measure of contribution margin when evaluating results of operations. Contribution margin is defined as operating revenues less natural and propane gas costs and gross receipts tax expense. The Utilities pass to their customers (subject to prudence review by, as applicable, the MoPSC, APSC or MSPSC) increases and decreases in the wholesale cost of natural gas in accordance with their PGA clauses or GSA riders. The volatility of the wholesale natural gas market results in fluctuations from period to period in the recorded levels of, among other items, revenues and natural gas cost expense. Nevertheless, increases and decreases in the cost of gas associated with system gas sales volumes and gross receipts tax expense (which are calculated as a percentage of revenues), with the same amount (excluding immaterial timing differences) included in revenues, have no direct effect on operating income. Therefore, management believes that contribution margin is a useful supplemental measure, along with the remaining operating expenses, for assessing the Company’s and the Utilities’ performance.

** Net economic earnings per share is calculated by replacing consolidated net income with consolidated net economic earnings in the GAAP diluted earnings per share calculation, which includes reductions for cumulative preferred dividends and participating shares.

Note: In the following discussion, all references to earnings (loss) per share and net economic earnings per share refer to earnings (loss) per common share and net economic earnings per common share.

Consolidated

Spire had net income of $67.0 for the three months ended December 31, 2019, compared with net income of $67.3 for the three months ended December 31, 2018. Basic and diluted earnings per share for the three months ended December 31, 2019 were $1.24, compared with basic earnings per share of $1.33 and diluted earnings per share of $1.32 for the three months ended December 31, 2018. Net income was flat versus the prior-year period, reflecting a $6.7 decrease in the Gas Marketing segment, mostly offset by a $5.7 lower loss in Other and slightly higher earnings in the Gas Utility segment. The Gas Marketing decrease represents a $5.9 ($4.5 after-tax) decline related to derivative activity and fair value measurements, combined with lower contribution margin. Other benefited from STL Pipeline coming online in the current quarter, combined with a smaller loss from Spire Storage, and lower interest expense. Gas Utility net income growth was negatively impacted by the $2.0 after-tax provision booked for the ISRS rulings provision in the current quarter.

47

Spire’s net economic earnings were $71.8 ($1.33 per diluted share) for the three months ended December 31, 2019, an increase of $5.9 from the $65.9 ($1.30 per diluted share) reported for the same period in the prior year. For the current quarter both net income per share and net economic earnings per share were reduced by approximately $0.07 per share due to dividends earned from the $250.0 in preferred shares that were issued in May 2019. Dividends on cumulative preferred shares are deducted from net income in the calculation of earnings per common share.

The principal drivers of the increase in net economic earnings were the $5.4 and $2.7 increases from Other and Gas Utility, respectively, partly offset by a $2.2 decrease in Gas Marketing, as reflected in the table. These impacts are described in further detail below.

Gas Utility

For the three months ended December 31, 2019, net economic earnings for the Gas Utility segment increased $2.7 from the first quarter of the prior year, primarily due to a $2.9 increase at Spire Alabama. The increase at Spire Alabama was primarily driven by higher contribution margins, partly offset by higher operating and maintenance (“O&M”) expenses and depreciation. Net economic earnings at Spire Missouri were essentially flat versus the prior-year quarter, as warmer weather restrained contribution margin and both O&M and depreciation expenses trended higher in the current year. These impacts are discussed in further detail below.

Gas Marketing

For the three months ended December 31, 2019, net economic earnings for the Gas Marketing segment were $6.1, a decrease of $2.2 compared with the first quarter of the prior year. The decrease in the current-year period was primarily driven by the increased costs of incremental transportation capacity and narrower basis differentials in the market, partly offset by the higher volumes from our continued business expansion.

Other

For the three months ended December 31, 2019, net economic loss for Other decreased $5.4 compared with the first quarter last year. This decrease reflects a $2.3 earnings increase due to the Spire STL Pipeline being completed and coming online during this quarter, a $0.7 lower loss associated with Spire Storage and lower interest expense due to lower net debt levels and slightly favorable short-term rates.

Consolidated

As shown in the table above, Spire reported operating revenue of $566.9 for the three months ended December 31, 2019, a decrease of $35.1 compared with the same period in the prior year. This decrease was due to a $44.5 reduction in the Gas Utility segment, which was partly offset by a $6.5 increase in Gas Marketing and a $5.7 increase in Other. Spire’s contribution margin increased $5.0 compared with last year, as increases in the Gas Utility segment of $7.1 and $5.7 for Other were partly offset by a $7.5 decrease in the Gas Marketing segment. Depreciation and amortization expenses were up $2.7 in the Gas Utility segment, reflecting the higher overall capital investments across all utilities. Gas Utility O&M expenses in the quarter were $3.7 higher than the prior-year quarter, primarily driven by a $2.2 increase in field distribution and maintenance expense and an increase in bad debt expense. These impacts are described in further detail below.

Gas Utility

Operating Revenues – Gas Utility operating revenues for the three months ended December 31, 2019, were $530.7, or $44.5 lower than the same period in the prior year. The decrease in Gas Utility operating revenues was attributable to the following factors:

Spire Missouri and Spire Alabama – Lower PGA/GSA cost recoveries	$	(26.2	)
Spire Missouri and Spire Alabama – Volumetric usage (net of weather mitigation)		(23.3	)
Spire Missouri and Spire Alabama – Off-system sales and capacity release, net		(5.3	)
Spire Alabama – RSE: Giveback		4.1
Spire Alabama – RSE: Annual rate renewal		2.8
Spire Missouri – ISRS, net of ISRS rulings provision		2.2
All other factors		1.2
Total Variation	$	(44.5	)

49

The decrease in revenues was primarily driven by lower gas cost recoveries, lower volumetric usage, and lower off-system sales at Spire Missouri that were partly offset by the commencement of off-system sales in the quarter by Spire Alabama. These negative impacts were only partly offset by the favorable $4.1 RSE adjustment and $2.8 RSE annual rate renewal at Spire Alabama, combined with Spire Missouri’s net ISRS revenues (after recording provision for ISRS rulings).

Contribution Margin – Gas Utility contribution margin was $264.6 for the three months ended December 31, 2019, a $7.1 increase over the same period in the prior year. The increase was attributable to the following factors:

Spire Alabama – RSE: Giveback	$	3.9
Spire Alabama – RSE: Annual rate renewal		2.5
Spire Missouri – ISRS, net of ISRS rulings provision		2.2
All other factors		2.3
Spire Missouri and Spire Alabama – Volumetric usage (net of weather mitigation)		(3.8	)
Total Variation	$	7.1

The increase in contribution margin was primarily attributable to a prior-year RSE adjustment of $3.9, in conjunction with a $2.5 increase due to RSE annual rate renewal at Spire Alabama, combined with Spire Missouri’s net ISRS amounts (after recording provision for ISRS rulings), partly offset by volumetric usage net of weather mitigation.

Operating Expenses – O&M expenses for the three months ended December 31, 2019 were $3.7 higher than the same period in the prior year primarily driven by higher field distribution, maintenance, and bad debt expense. The increase reflects a $2.4 increase at Spire Missouri, combined with a $0.8 increase at Spire Alabama. Depreciation and amortization expenses for the three months ended December 31, 2019 were $2.7 higher than the same period in the prior year primarily driven by higher levels of capital expenditures across all the Utilities.

Gas Marketing

Operating Revenues – Operating revenues increased $6.5 versus the prior-year period as higher volumetric gas sales were partly offset by the impact of lower general pricing this quarter versus the prior year quarter. Average pricing for the three months ended December 31, 2019, was approximately $2.25/MMBtu versus approximately $3.51/MMBtu for the quarter ended December 31, 2018.

Contribution Margin – Gas Marketing contribution margin during the three months ended December 31, 2019 decreased $7.5 from the same period in the prior year, largely reflecting a $5.9 ($4.5 after-tax) decline in derivative activity and fair value measurements excluded from net economic earnings. Excluding these losses, margins decreased by $1.6 from the prior year, as higher volumes associated with the segment’s business expansion were offset by the costs of incremental transportation capacity and the impact of lower basis differentials.

Interest Charges

Consolidated interest charges during the three months ended December 31, 2019, increased by $0.8 from the same period in the prior year. The increase was primarily driven by net long-term debt issuances at the Gas Utilities and Spire STL Pipeline and higher average levels of short-term borrowings that were partly offset by lower short-term rates. For the three months ended December 31, 2019 and 2018, average short-term borrowings were $727.7 and $622.9, respectively, and the average interest rates on these borrowings were 2.2% and 2.7%, respectively.

Income Taxes

Consolidated income tax for the three months ended December 31, 2019 versus the same period in the prior year reflects slightly lower effective tax rates in the current year quarter versus the prior year, along with the change in pre-tax income.

Net Income	$	48.0		$	51.2

Operating revenues for the three months ended December 31, 2019, decreased $39.2 from the same period in the prior year primarily due to $23.3 lower gas cost recoveries and an $11.7 decrease in volumetric usage (net of weather mitigation) resulting from warmer weather in the current year quarter. A further $5.7 reduction was attributable to lower off-system sales in the current year versus the prior-year quarter. A net increase (after ISRS ruling provision of $2.1) of ISRS revenues totaling $2.2 only partly offset these negative impacts. Contribution margin for the three months ended December 31, 2019, decreased $0.3 from the same period in the prior year, largely due to the lower volumetric usage of $2.7, partly offset by ISRS amounts mentioned above.

O&M expenses for the three months ended December 31, 2019 increased $2.4 primarily due to higher field distribution costs and bad debt expense. Depreciation and amortization increased $1.8 in the current quarter versus the prior-year quarter due to higher capital investments.

Degree days in Spire Missouri’s service areas during the three months ended December 31, 2019, were 3% colder than normal but 6% warmer than the same period last year, resulting in lower usage on a year-over-year comparative basis. The Missouri Utilities’ total system therms sold and transported were 556.1 million for the three months ended December 31, 2019, compared with 589.0 million for the same period in the prior year. Total off-system therms sold and transported were 8.7 million for the three months ended December 31, 2019, compared with 23.1 million for the same period last year.

Resulting net income for the quarter ended December 31, 2019 decreased $3.2 versus the prior-year quarter.

51

Operating revenues for the three months ended December 31, 2019, decreased $7.3 from the same period in the prior year. The change in operating revenue was driven principally by lower current-year volumetric usage impacts of $11.6, and a $2.9 decrease in gas cost recoveries versus the prior year, offset by a prior-year RSE adjustment of $4.1 that did not repeat and $2.8 due to the RSE annual rate renewal. Contribution margin increased $5.3, primarily due to $3.9 attributable to the RSE adjustment and $2.5 to the RSE annual rate renewal more than offsetting weather-related impacts.

O&M expenses for the three months ended December 31, 2019 increased only $0.8 versus the prior-year quarter. Depreciation and amortization expenses for the three months ended December 31, 2019, were $0.7 higher than the same period last year, the result of continued infrastructure investment.

For the quarter ended December 31, 2019 resulting net income increased $2.9 versus the prior-year quarter.

As measured in degree days, temperatures in Spire Alabama’s service area during the three months ended December 31, 2019 were 14% colder than normal but 16% warmer than a year ago. Spire Alabama’s total system therms sold and transported were 283.1 million for the three months ended December 31, 2019, compared with 288.2 million for the same period in the prior year.

REGULATORY MATTERS

For discussions of regulatory matters for Spire, Spire Missouri, and Spire Alabama, see Note 4, Regulatory Matters, of the Notes to Financial Statements in Item 1.

CRITICAL ACCOUNTING ESTIMATES

Our discussion and analysis of our financial condition, results of operations, liquidity, and capital resources are based upon our financial statements, which have been prepared in accordance with GAAP. GAAP requires that we make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We evaluate our estimates on an ongoing basis. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. Our critical accounting estimates used in the preparation of our financial statements are described in Item 7 of the Company’s, Spire Missouri’s, and Spire Alabama’s combined Annual Report on Form 10-K for the fiscal year ended September 30, 2019, and include regulatory accounting, employee benefits and postretirement obligations, and income taxes. There were no significant changes to critical accounting estimates during the three months ended December 31, 2019.

For discussion of other significant accounting policies, see Note 1 of the Notes to Financial Statements included in this Form 10-Q as well as Note 1 of the Notes to Financial Statements included in the Company’s, Spire Missouri’s, and Spire Alabama’s combined Annual Report on Form 10-K for the fiscal year ended September 30, 2019.

ACCOUNTING PRONOUNCEMENTS

The Company, Spire Missouri and Spire Alabama have evaluated or are in the process of evaluating the impact that recently issued accounting standards will have on the companies’ financial position or results of operations upon adoption. For disclosures related to the adoption of new accounting standards, see the New Accounting Pronouncements section in Note 1 of the Notes to Financial Statements in Item 1.

52

LIQUIDITY

The Company’s short-term borrowing requirements typically peak during colder months when the Utilities borrow money to cover the lag between when they purchase natural gas and when their customers pay for that gas. Changes in the wholesale cost of natural gas (including cash payments for margin deposits associated with Spire Missouri’s use of natural gas derivative instruments), variations in the timing of collections of gas cost under the Utilities’ PGA clauses and GSA riders, the seasonality of accounts receivable balances, and the utilization of storage gas inventories cause short-term cash requirements to vary during the year and from year to year, and may cause significant variations in the Company’s cash provided by or used in operating activities.

	Three Months Ended December 31,
Cash Flow Summary	2019			2018
Net cash provided by operating activities	$	64.5		$	70.4
Net cash used in investing activities		(192.6	)		(216.2	)
Net cash provided by financing activities		143.8			132.8

For the three months ended December 31, 2019, net cash provided by operating activities decreased $5.9 from the corresponding period of fiscal 2019. The change was due principally to the timing of accounts receivable and fluctuations in working capital items, as discussed above.

For the three months ended December 31, 2019, net cash used in investing activities was $23.6 less than for the same period in the prior year, driven by a $14.5 decrease in capital expenditures and $7.9 less outflows relating to acquisition-related activity. The lower capital spending in the current year is consistent with the Company’s capital expenditure expectations and reflects more infrastructure upgrades at the Utilities, support of customer growth, new business development initiatives, partly offset by lower expenditures related to Spire Storage and the completion in the current quarter of Spire STL Pipeline. Total capital expenditures for the full fiscal year 2020 are expected to be approximately $610.

Lastly, for the three months ended December 31, 2019, net cash provided by financing activities was $143.8, versus net cash provided of $132.8 for the three months ended December 31, 2018. This change primarily reflects issuance of long-term debt of $510.0 this year versus $100.0 in the prior year, offset by a combined $387.6 higher short- and long-term borrowing repayments in the current year, and an increase in common stock and preferred stock dividends paid of $5.9 and $3.7, respectively, in the current year.

CAPITAL RESOURCES

The Company’s, Spire Missouri’s and Spire Alabama’s access to capital markets, including the commercial paper market, and their respective financing costs, may depend on the credit rating of the entity that is accessing the capital markets. Our debt is rated by two rating agencies: Standard & Poor’s Corporation (“S&P”) and Moody’s Investors Service (“Moody’s”). As of December 31, 2019, the debt ratings of the Company, Spire Missouri and Spire Alabama, shown in the following table, remain at investment grade with a stable outlook.

	S&P	Moody’s
Spire Inc. senior unsecured long-term debt	BBB+	Baa2
Spire Inc. preferred stock	BBB	Ba1
Spire Inc. short-term debt	A-2	P-2
Spire Missouri senior secured long-term debt	A	A1
Spire Alabama senior unsecured long-term debt	A-	A2

It is management’s view that the Company, Spire Missouri and Spire Alabama have adequate access to capital markets and will have sufficient capital resources, both internal and external, to meet anticipated capital requirements, which primarily include capital expenditures, interest payments on long-term debt, scheduled maturities of long-term debt, short-term seasonal needs and dividends.

Cash and Cash Equivalents

Bank deposits were used to support working capital needs of the business. Spire had no temporary cash investments as of or during the three months ended December 31, 2019.

Short-term Debt

The Utilities’ short-term borrowing requirements typically peak during the colder months, while most of the Company’s other needs are less seasonal. These short-term cash requirements can be met through the sale of commercial paper or through the use of a revolving credit facility. For information about these resources, see Note 5, Financing Arrangements and Long-term Debt, of the Notes to Financial Statements in Item 1.

Long-term Debt and Equity

At December 31, 2019, including the current portion but excluding unamortized discounts and debt issuance costs, Spire had long-term debt totaling $2,547.0, of which $1,105.0 was issued by Spire Missouri, $515.0 was issued by Spire Alabama, and $237.0 was issued by other subsidiaries. For more information about long-term debt, see Note 5 of the Notes to Financial Statements in Item 1.

Spire Missouri was authorized by the MoPSC to issue registered securities (first mortgage bonds, unsecured debt and preferred stock), common stock, and private placement debt in an aggregate amount of up to $500.0 for financings placed any time before September 30, 2021. As of December 31, 2019, $125.0 remained available under this authorization. Spire Alabama has no standing authority to issue long-term debt and must petition the APSC for each planned issuance. On July 9, 2019, the APSC approved $100.0 of additional long-term financing, which was ultimately issued by Spire Alabama on December 2, 2019.

Spire has a shelf registration statement on Form S-3 on file with the U.S. Securities and Exchange Commission (SEC) for the issuance and sale of up to 250,000 shares of common stock under its Dividend Reinvestment and Direct Stock Purchase Plan. There were 129,609 and 125,449 shares at December 31, 2019 and January 31, 2020, respectively, remaining available for issuance under this Form S-3. Spire and Spire Missouri also have a universal shelf registration statement on Form S-3 on file with the SEC for the issuance of various equity and debt securities, which expires on May 14, 2022.

On February 6, 2019, Spire entered into an “at-the-market” equity distribution agreement, supplemented as of May 14, 2019, pursuant to which the Company may offer and sell, from time to time, shares of its common stock having an aggregate offering price of up to $150.0. Those shares are issued pursuant to Spire’s universal shelf registration statement referenced above and a prospectus supplement dated May 14, 2019. In the year ended September 30, 2019, Spire issued 179,630 shares under this program, generating $14.4 of proceeds net of issuance costs. In the quarter ended December 31, 2019, Spire did not issue shares under this program.

Including the current portion of long-term debt, the Company’s long-term consolidated capitalization at December 31, 2019 consisted of 51% equity, compared to 55% equity at September 30, 2019.

CONTRACTUAL OBLIGATIONS

During the three months ended December 31, 2019, there were no material changes outside the ordinary course of business to the estimated contractual obligations from the disclosure provided in the Company’s Form 10-K for the fiscal year ended September 30, 2019.

54

MARKET RISK

There were no material changes in the Company’s commodity price risk or counterparty credit risk as of December 31, 2019, relative to the corresponding information provided in the Company’s Annual Report on Form 10-K as of September 30, 2018. In August 2018, Spire entered into a three-year interest rate swap with a fixed interest rate of 2.7675% and a notional amount of $100.0 to protect itself against adverse movements in interest rates on future interest rate payments. In the fourth quarter of 2019, this hedge was settled, resulting in a loss of $2.5 which is being amortized over the remaining hedged periods. During the first quarter of fiscal 2019, the Company entered into a three-year interest rate swap with a fixed interest rate of 3.250% and a notional amount of $100.0 to protect itself against adverse movements in interest rates on future interest rate payments. The Company recorded a $24.5 mark-to-market loss on this swap for the three months ended December 31, 2019.

ENVIRONMENTAL MATTERS

The Utilities and other Spire subsidiaries own and operate natural gas distribution, transmission and storage facilities, the operations of which are subject to various environmental laws and regulations, along with their interpretations. While environmental issues resulting from such operations arise in the ordinary course of business, such issues have not materially affected the Company’s, Spire Missouri’s, or Spire Alabama’s financial position and results of operations. As environmental laws, regulations, and interpretations change, however, the Company and the Utilities may be required to incur additional costs. For information relative to environmental matters, see Contingencies in Note 11 of the Notes to Financial Statements in Item 1.

OFF-BALANCE SHEET ARRANGEMENTS

At December 31, 2019, the Company had no off-balance-sheet financing arrangements other than operating leases, surety bonds, and letters of credit entered into in the ordinary course of business. The Company does not expect to engage in any significant off-balance-sheet financing arrangements in the near future.

(F/K/A LACLEDE GAS COMPANY), a corporation of the State of Missouri (hereinafter called “the Company”), for value received hereby promises to pay to _______________ or registered assigns, at the office or agency of the Company in the City of St. Louis, State of Missouri, _____________________ Dollars on the 15th day of November, 2029 (or upon earlier redemption), by check or draft (or as otherwise provided herein) in such coin or currency of the United States of America as at the time of payment shall be legal tender for public and private debts, and to pay to the registered owner hereof by check or draft (or as otherwise provided herein) interest thereon from and including November 12, 2019 or from the fifteenth day of May or November next preceding the date of this bond to which date interest has been paid or duly provided for (or, if this bond is dated any date after the record date for any interest payment date and on or before such interest payment date, then from such interest payment date), at the rate of 2.84% per annum, in like coin or currency at either of said offices or agencies at the option of the registered owner hereof, on May 15 and November 15 in each year, commencing on May 15, 2020, until the Company’s obligation with respect to the payment of such principal shall have been discharged. If any interest payment date or any date of maturity or redemption of principal of this bond falls on a day that is not a Business Day (as defined below), principal and/or interest payable on such date will be paid on the succeeding Business Day with the same force and effect as if it were paid on the date such payment was due, and no interest will accrue on the amount so payable for the period from and after such date to such succeeding Business Day. “Business Day” means any day other than a Saturday, Sunday, or other day on which commercial banks are authorized or required by law, regulation, or executive order to close in the City of St. Louis, State of Missouri or on which the corporate trust office of the Trustee is closed for business. The interest so payable on any May 15 or November 15 will, subject to certain exceptions provided in the Mortgage hereinafter mentioned, be paid to the person in whose name this bond is registered at the close of business on the record date, which shall be May 1 or November 1, as the case may be, next preceding such interest payment date (whether or not a Business Day). Notwithstanding the foregoing, so long as the holder is The Depository Trust Company ("DTC") or a nominee thereof, such payments of principal and interest will be made in accordance with the Blanket Issuer Letter of Representations dated April 20, 2004 between DTC and the Company (or such successor arrangement thereto). If a registered owner of an aggregate principal amount in excess of $100,000 of the bonds so requests, payments of principal and interest to that registered owner shall be made

12

by electronic transfer to an account at a commercial bank or savings institution located in the continental United States designated in writing by such registered owner. Any such request must be made in writing to the Company and UMB Bank & Trust, n.a. (hereinafter sometimes referred to as the “Trustee”) at least 10 days in advance of such payment and must specify the name and address of the receiving bank, its ABA routing number, and the account name and number to receive the electronic transfer.

This bond is one of an issue of bonds of the Company, issuable in series, and is one of a series known as its First Mortgage Bonds due November 15, 2029 (hereinafter referred to as the “Bonds”), all bonds of all series issued and to be issued under and equally secured (except in so far as any sinking or other fund established in accordance with the provisions of the Mortgage hereinafter mentioned may afford additional security for the bonds of any particular series) by a Mortgage and Deed of Trust (hereinafter referred to as the “Original Indenture”) dated as of February 1, 1945, executed by the Company to Mississippi Valley Trust Company, which was succeeded through consolidation by Mercantile Trust Company, which was succeeded by Mercantile Trust Company National Association, which was succeeded by Mercantile Bank National Association, which was succeeded by Mercantile Bank of St. Louis National Association, which was succeeded by State Street Bank and Trust Company of Missouri, N.A., which in turn was succeeded by UMB Bank & Trust, n.a., as Trustee, and indentures supplemental thereto, including the Thirty-Fourth Supplemental Indenture thereto dated as of November 12, 2019 (hereinafter referred to as the “Thirty-Fourth Supplemental Indenture”), said Mortgage and Deed of Trust as supplemented being herein called the “Mortgage,” to which reference is made for a description of the property mortgaged and pledged, the nature and extent of the security, the rights of the owners of the bonds in respect thereof, the duties and immunities of the Trustee, and the terms and conditions upon which the bonds are secured.

The Bonds are redeemable prior to maturity, in whole or in part, upon the notice referred to below, and otherwise subject to the provisions of the Mortgage: (i) pursuant to paragraph (B) of Section 13.06 of the Original Indenture (having reference to the taking of all the mortgaged property by eminent domain and certain comparable contingencies) at 100% of the principal amount thereof, together with accrued interest thereon to the date fixed for redemption; or

13

(ii) pursuant to Section 3.2 of the Thirty-Fourth Supplemental Indenture at a redemption price equal to 100% of the principal amount to be redeemed plus the Make-Whole Amount (as defined in the Thirty-Fourth Supplemental Indenture) determined for the redemption date with respect to such principal amount, plus, in each case, accrued interest thereon to the date fixed for redemption without premium. The Company will give each holder of Bonds written notice of each optional redemption under Section 3.2 of the Thirty-Fourth Supplemental Indenture not less than thirty (30) days and not more than sixty (60) days prior to the date fixed for such redemption. Each such notice shall specify such redemption date (which shall be a Business Day), the aggregate principal amount of the bonds to be redeemed on such date, the principal amount of each bond held by such holder to be redeemed (determined in accordance with Section 3.2 of the Thirty-Fourth Supplemental Indenture), and the interest to be paid on the redemption date with respect to such principal amount being redeemed, and, if applicable, shall be accompanied by a certificate of the chief financial officer, principal accounting officer, treasurer or controller of the Company (each a “Senior Financial Officer”) as to the estimated Make-Whole Amount due in connection with such redemption (calculated as if the date of such notice were the date of the redemption), setting forth the details of such computation. Two Business Days prior to a redemption pursuant to clause (ii) above if such redemption is to occur prior to the Par Call Date (as defined in the Thirty-Fourth Supplemental Indenture), the Company shall deliver to each holder of Bonds a certificate of a Senior Financial Officer specifying the calculation of such Make-Whole Amount as of the specified redemption date. Except as set forth above, the Bonds are not redeemable prior to November 15, 2029.

The principal hereof and the interest accrued hereon may be declared or may become due on the conditions, in the manner, and at the time set forth in the Mortgage, upon the occurrence of a completed default as in the Mortgage provided.

At the option of the registered owner, any Bonds, upon surrender thereof at the office or agency of the Company in the City of St. Louis, State of Missouri, together with a written instrument of transfer in form approved by the Company duly executed by the registered owner or his duly authorized attorney, shall, subject to the provisions of Section 2.05 of the Original Indenture, be exchangeable for a like aggregate amount of fully registered bonds of the same series of other authorized denominations.

This bond is transferable as prescribed in the Mortgage by the registered owner hereof in person, or by his duly authorized attorney, at the office or agency of the Company in the City of St. Louis, upon surrender and cancellation of this bond and upon presentation of a written instrument of transfer, duly executed, with signature guaranteed by a signature guarantor that is a participant in a nationally recognized signature guaranty program, and upon payment, if the Company shall require it, of the transfer charges prescribed in the Mortgage, and thereupon, a new fully registered bond of the same series for a like principal amount will be issued to the transferee in exchange herefor as provided in the Mortgage. The Company and the Trustee may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment and for all other purposes.

No recourse shall be had for the payment of the principal of or of interest on this bond against any incorporator or any past, present or future subscriber to the capital stock, stockholder, officer or director of the Company or of any predecessor or successor corporation, as such, either

14

directly or through the Company or any predecessor or successor corporation, under any rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers, stockholders, officers and directors, as such, being released by the owner hereof by the acceptance of this bond and being likewise waived and released by the terms of the Mortgage.

Each holder of this bond will be deemed, by its acceptance hereof, to have (i) agreed to the confidentiality provisions set forth in Section 16 of the Bond Purchase Agreement dated as of November 12, 2019, between the Company and the purchasers of Bonds listed in Schedule A thereto (the “Bond Purchase Agreement”) and (ii) made the representations set forth in Section 6.1 of the Bond Purchase Agreement.

Anything in this Thirty-Fourth Supplemental Indenture to the contrary notwithstanding, the Company shall not be required to make transfers or exchanges of Bonds for a period of fifteen (15) days next preceding any selection of Bonds to be redeemed, and the Company shall not be required to make transfers or exchanges of the principal amount of any of such bonds called or selected for redemption except in the case of any Bond to be redeemed in part, the portion thereof not to be so redeemed.

SECTION 2.9 Restrictive Legend. Bonds offered and sold to “accredited investors” (within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act of 1933, as amended) shall be issued substantially in the form of such bonds set forth in the Recitals to this Thirty-Fourth Supplemental Indenture, containing the first legend set forth thereon (for purposes of this Section 2.9, the “Restrictive Legend”) and the other legends required thereby and numbered from 1 upward with the prefix “R”, duly executed by the Company and authenticated by the Trustee as herein provided.

23

The Company shall issue a Bond that does not bear the Restrictive Legend in replacement of a bond of the applicable series bearing the Restrictive Legend at the request of any holder following such request if (i) the holder shall have obtained an opinion of counsel reasonably acceptable to the Company in form and substance reasonably satisfactory to the Company to the effect that such bond may lawfully be disposed of without registration, qualification or legend pursuant to Rule 144 under the Securities Act of 1933, as amended, or (ii) the holder sells such bond pursuant to Rule 144 under the Securities Act of 1933, as amended, or an effective registration statement.

ARTICLE III

REDEMPTION OF BONDS

SECTION 3.1 Circumstances in Which Redeemable. Bonds shall be redeemable, in whole or in part, at 100% of the principal amount thereof, together with accrued interest thereon to the date fixed for redemption at any time before maturity pursuant to the provisions of paragraph (B) of Section 13.06 of the Original Indenture.

SECTION 3.2 Additional Circumstances in Which Redeemable. Bonds shall also be redeemable, at the option of the Company, in whole at any time or in part from time to time, at a redemption price equal to 100% of the principal amount to be redeemed plus the Make-Whole Amount (as defined below) determined for the redemption date with respect to such principal amount, plus accrued interest thereon to the date fixed for redemption without premium. Any redemption in part under this Section 3.2 shall be made pro rata to the holders of all Bonds at the time outstanding upon the same terms and conditions.

For purposes of this Section 3.2:

“Make-Whole Amount” means, with respect to any Bond, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such bond over the amount of such Called Principal, provided that on and after the Par Call Date, the Make-Whole Amount on such Bond shall equal zero; provided further that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:

“Business Day” shall have the meaning set forth in the form of Bond.

“Called Principal” means, with respect to any bond, the principal of such bond that is to be redeemed or has become or is declared to be immediately due and payable pursuant to the Mortgage, as the context requires.

“Discounted Value” means, with respect to the Called Principal of any bond, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the bonds is payable) equal to the Reinvestment Yield with respect to such Called Principal.

24

“Reinvestment Yield” means, with respect to the Called Principal of any bond, .50% over the yield to maturity implied by (i) the yields reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on the run U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date.

In the case of each determination under clause (i) or clause (ii), as the case may be, of the preceding paragraph, such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) the applicable U.S. Treasury security with the maturity closest to and greater than such Remaining Average Life and (2) the applicable U.S. Treasury security with the maturity closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable bond.

“Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

“Remaining Scheduled Payments” means, with respect to the Called Principal of any bond, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Bonds, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to this section.

“Par Call Date” means, with respect to the Bonds, August 15, 2029.

“Settlement Date” means, with respect to the Called Principal of any bond, the date on which such Called Principal is to be redeemed pursuant to this section.

25

SECTION 3.3 Purchase of Bonds. The Company will not and will not permit any affiliate to purchase, redeem or otherwise acquire, directly or indirectly, any of the outstanding Bonds except (a) upon the redemption of such bonds in accordance with the terms of Section 3.2 hereof and such bonds or (b) pursuant to an offer to purchase made by the Company or an affiliate pro rata to the holders of all Bonds at the time outstanding upon the same terms and conditions. Any such offer shall provide each holder with sufficient information to enable it to make an informed decision with respect to such offer, and shall remain open for at least 10 Business Days. If the holders of more than 25% of the principal amount of the Bonds then outstanding accept such offer, the Company shall promptly notify the remaining holders of such fact and the expiration date for the acceptance by holders of Bonds of such offer shall be extended by the number of days necessary to give each such remaining holder at least 10 Business Days from its receipt of such notice to accept such offer. The Company will promptly cancel all bonds acquired by it or any affiliate pursuant to any payment, redemption or purchase of bonds pursuant to this Article III and no bonds may be issued in substitution or exchange for any such bonds.

SECTION 3.4 Notice of Intention to Redeem. Article XII of the Original Indenture is and shall be applicable to any redemption of Bonds. The notice of intention to redeem provided for in Section 12.02 of the Original Indenture need not be published with respect to Bonds but shall be given by mailing a copy thereof to each registered owner thereof, directed to his registered address, not less than thirty (30) nor more than sixty (60) days prior to the date fixed for redemption.

SECTION 3.5 No Other Redemptions. Except as set forth in Section 3.1 and Section 3.2 hereof, the Bonds are not redeemable prior to November 15, 2029.

ARTICLE IV

PARTICULAR COVENANTS OF THE COMPANY

SECTION 4.1 Restrictions as to Dividends. So long as any of the Bonds are outstanding, the Company will not (a) declare any dividends (other than dividends in common stock) on any common stock, or order the making of any distribution on any shares of common stock or to owners of common stock or (b) purchase, redeem or otherwise acquire or retire for value any shares of common stock, if the aggregate net amount of such declarations, distributions so ordered, purchases, redemptions, acquisitions and retirements after September 30, 1953, would exceed the sum of (y) the Net Income Available for Common Stock for the period beginning October 1, 1953, and ending with the last day of the calendar quarter immediately preceding the calendar quarter in which such dividend is declared, distribution ordered, or purchase, redemption, acquisition or retirement made, plus (z) Eight Million Dollars ($8,000,000).

The aggregate net amount of the declarations, distributions ordered, purchases, redemptions, acquisitions and retirements referred to in the first paragraph of this Section 4.1 shall be determined by deducting from the aggregate amount thereof the total amount of cash payments received by the Company after September 30, 1953, for any shares of common stock sold by the Company after September 30, 1953.

Net Income Available for Common Stock, for the purpose of this Section 4.1, for any period, means (1) the net income of the Company for such period computed according to the

26

applicable system of accounts prescribed by the Public Service Commission of Missouri and any applicable orders of said Commission and (to the extent not prescribed by such system of accounts or orders) according to generally accepted accounting principles, less (2) an amount equal to the dividends accrued (whether or not declared or paid) during such period on any and all classes of stock having preference over the common stock as to assets or dividends.

For the purposes of the last preceding paragraph of this Section 4.1, the term “Public Service Commission of Missouri” shall also apply, and be deemed to refer, to any regulatory body which may (A) succeed said Commission with respect to jurisdiction over the accounting of the Company, or (B) supersede said Commission with respect to such jurisdiction, or (C) have such jurisdiction over phases of the Company’s business or parts of its property over which said Commission shall not have jurisdiction.

SECTION 4.2 Earnings Requirements for Additional Bonds. So long as any Bonds are outstanding, the Company shall not be entitled to have authenticated and delivered any bonds pursuant to Article VI, Article VII or Article VIII of the Original Indenture, except bonds which may be authenticated and delivered under Article VII of the Original Indenture, without the receipt by the Trustee of a net earnings certificate showing the net earnings to be as required by Section 6.05 of the Original Indenture, unless (in addition to all other requirements for the authentication and delivery of such bonds):

(a)net earnings of the Company after provision for depreciation, depletion and amortization of property, for any 12 consecutive calendar months within the 15 calendar months immediately preceding the date on which such additional bonds are to be issued, shall have been not less than 2 1/4 times the amount of the total annual interest charges upon the funded debt of the Company to be outstanding immediately after the issue of such additional bonds; and

(b)the Trustee shall have received a certificate made, signed and verified by the same persons (including an independent public accountant where required) as would be required if such certificate were a net earnings certificate under the Original Indenture, showing the net earnings of the Company to be as required by the foregoing clause (a) of this Section 4.2. Such certificate shall show the net earnings and total annual interest charges referred to in said clause (a).

For the purposes of this Section 4.2, “funded debt” shall mean all indebtedness created or assumed by the Company maturing one year or more after the date of the creation or assumption thereof.

For the purposes of this Section 4.2, net earnings of the Company after provision for depreciation, depletion and amortization of property shall mean the total operating revenue and other income (net) of the Company less operating expenses (including provision for depreciation, depletion and amortization of property) and less taxes (excluding income and excess profits taxes or other taxes which are imposed on or measured by income). In the determination of net earnings of the Company the following additional requirements shall be applicable:

(i)    No profits or losses from the sale or abandonment of capital assets or change in value of securities or other investments shall be taken into account in making such computations;

27

(ii)In case the Company shall have sold any property for a consideration in excess of $5,000,000, within or after the particular period for which the calculation is made, then, in computing the net earnings of the Company so available, the net earnings or net losses of such property for the whole of such period shall be excluded to the extent practicable on the basis of actual earnings and expenses of such property or on the basis of such estimates of the earnings and expenses of such property as the signers of a Treasurer’s certificate filed with the Trustee shall deem proper;

(iii)    In case the Company shall, within or after the particular period for which the calculation is made, have acquired (by purchase, merger, consolidation or otherwise) any property which within six months prior to the date of acquisition thereof by the Company has been used or operated by a person or persons other than the Company in a business similar to that in which it has been or is to be used or operated by the Company, then in computing the net earnings of the Company so available for such purposes there shall be included, to the extent that they may not have been otherwise included, the net earnings or net losses of the property so acquired for the whole of such period to the extent practicable on the basis of actual earnings and expenses of such property or on the basis of such estimates of the earnings and expenses of such property as the signers of a Treasurer’s certificate filed with the Trustee shall deem proper. The net earnings or net losses of such property for the period preceding such acquisition shall in such case be ascertained and computed as provided in this clause (iii) as if such acquired property had been owned by the Company during the whole of such period; and

(iv)    The “net earnings of property” referred to in clauses (ii) and (iii) of this Section 4.2 shall mean the net earnings of such property computed in the manner provided in this definition for the computation of net earnings of the Company available for the pertinent purposes.

All accounting determinations required by this Section 4.2 shall (except to the extent, if any, to which the preceding provisions of this Section 4.2 may conflict with this provision) be made according to the applicable system of accounts prescribed by the Public Service Commission of Missouri and any applicable orders of said Commission and (to the extent not prescribed by such system of accounts or orders) according to generally accepted accounting principles.

For the purposes of this Section 4.2, the term “Public Service Commission of Missouri” shall be applicable as provided in Section 4.1 of this Article IV.

SECTION 4.3 Postponement of Interest. So long as any Bonds are outstanding, in order that any interest payment on the Bonds may be postponed pursuant to clause (2) of Section 20.07 of the Original Indenture, there shall be required, in addition to all other prerequisites to such postponement provided in the Original Indenture, the consent of the owners of not less than seventy-five percent (75%) in principal amount of Bonds at the time outstanding, such consent to be given at the same time as and in the same manner as the consent of the owners of other bonds required by said clause (2) of Section 20.07 of the Original Indenture.

Concentrations of Credit Risk

Risks And Uncertainties [Abstract]

Concentrations of Credit Risk

8. CONCENTRATIONS OF CREDIT RISK

Spire’s Gas Utility segment serves 1.7 million customers in three states across multiple rate classes resulting in a significant amount of revenue diversity. Credit risk is mitigated by the high percentage of residential customers as well as the geographic diversity of the Utilities, though customers for each Utility are concentrated in a single state.

A significant portion of Spire Marketing’s transactions are with (or are associated with) energy producers, utility companies, and pipelines. The concentration of transactions with these counterparties has the potential to affect the Company’s overall exposure to credit risk, either positively or negatively, in that each of these three groups may be affected similarly by changes in economic, industry, or other conditions. To manage this risk, as well as credit risk from significant counterparties in these and other industries, Spire Marketing has established procedures to determine the creditworthiness of its counterparties. These procedures include obtaining credit ratings and credit reports, analyzing counterparty financial statements to assess financial condition, and considering the industry environment in which the counterparty operates. This information is monitored on an ongoing basis. In some instances, Spire Marketing may require credit assurances such as prepayments, letters of credit, or parental guaranties. In addition, Spire Marketing may enter into netting arrangements to mitigate credit risk with counterparties in the energy industry with whom it conducts both sales and purchases of natural gas. Sales are typically made on an unsecured credit basis with payment due the month following delivery. Accounts receivable amounts are closely monitored and provisions for uncollectible amounts are accrued when losses are probable. Spire Marketing records accounts receivable, accounts payable, and prepayments for physical sales and purchases of natural gas on a gross basis. The amount included in its accounts receivable attributable to energy producers and their marketing affiliates totaled $20.9 at December 31, 2019 ($11.7 reflecting netting arrangements). Spire Marketing’s accounts receivable attributable to utility companies and their marketing affiliates totaled $84.2 at December 31, 2019 ($75.4 reflecting netting arrangements).

Spire Marketing also has concentrations of credit risk with pipeline companies associated with its natural gas receivable and with certain individually significant counterparties. At December 31, 2019, the amounts included in accounts receivable from its five largest counterparties (in terms of net accounts receivable exposure) totaled $33.6 ($30.7 reflecting netting arrangements). Of these five counterparties, two are investment-grade rated utilities. Of the three that are not rated, one has its outstanding credit guaranteed by a creditworthy subsidiary of an investment-grade rated company, another is not rated but each of its owners is investment-grade, and the third has its outstanding credit supported by a parental guaranty.

A portion of the Company’s and Spire Missouri’s regulatory assets are not earning a return, as shown in the table below:

	December 31,		September 30,		December 31,
	2019		2019		2018
Spire
Pension and postretirement benefit costs	$	208.0	$	211.1	$	141.2
Future income taxes due from customers		111.6		108.8		99.1
Other		14.1		14.3		14.3
Total Regulatory Assets Not Earning a Return	$	333.7	$	334.2	$	254.6
Spire Missouri
Pension and postretirement benefit costs	$	208.0	$	211.1	$	141.2
Future income taxes due from customers		104.9		102.9		96.7
Other		14.1		14.3		14.3
Total Regulatory Assets Not Earning a Return	$	327.0	$	328.3	$	252.2

Like all the Company’s regulatory assets, these regulatory assets are expected to be recovered from customers in future rates. The recovery period for the future income taxes due from customers and pension and other postretirement benefit costs could be 20 years or longer, based on current Internal Revenue Service guidelines and average remaining service life of active participants, respectively. The other items not earning a return are expected to be recovered over a period not to exceed 15 years, consistent with precedent set by the MoPSC. Spire Alabama does not have any regulatory assets that are not earning a return.

On March 7, 2018, the MoPSC issued its order in two general rate cases (docketed as GR-2017-0215 and GR-2017-0216), approving new tariffs that became effective on April 19, 2018. Certain provisions of the order allow less future recovery of certain deferred or capitalized costs than estimated based upon previous rate proceedings, and management determined that the related regulatory assets should be written down or off in connection with the preparation of the financial statements for the second quarter of 2018. The charges totaled $38.4 for the year ended September 30, 2018 and are included primarily in operation and maintenance expense on the statements of income and in other cash flows from operating activities on the statements of cash flows. The after-tax reduction to net income and earnings per share was $23.6 and $0.49, respectively. On April 25, 2018, Spire Missouri filed an appeal of the MoPSC’s order related to the disallowance of certain pension costs incurred prior to 1997 ($28.8), real estate sold in 2014 ($1.8), and rate case expenses ($0.9) to Missouri’s Southern District Court of Appeals. On March 15, 2019, the appeal was denied by the Southern District Court of Appeals, and Spire Missouri requested review by the Missouri Supreme Court, which agreed to take the case. Oral arguments were made before the Missouri Supreme Court on January 29, 2020. The charges related to the long-standing pension and real estate assets, totaling $30.6, were excluded in the determination of 2018 net economic earnings.

Spire Missouri filed Infrastructure System Replacement Surcharge (ISRS) applications which were approved by the MoPSC and the costs associated therewith were included in new tariffs that went into effect from our last general rate cases on April 19, 2018.  Since the Company’s last rate cases, ISRS filings became effective on October 8, 2018, May 25, 2019 and November 16, 2019, bringing total authorized future annualized ISRS revenues for Spire Missouri to $29.2. On February 3, 2020, Spire Missouri filed new ISRS applications with the MoPSC for a total of $16.3, including $5.3 of ISRS revenues previously disallowed.

As reported last year, on November 19, 2019, the Missouri Western District Court of Appeals issued rulings (“ISRS rulings”) that determined certain capital investments in 2016 through 2018 were not eligible for recovery under the ISRS. The ISRS rulings upheld appeals by the Office of Public Counsel (OPC) that contested recovery of portions of Spire Missouri’s ISRS and overturned the three prior MoPSC decisions.

Spire Missouri strongly disagrees with the ISRS rulings and plans to vigorously defend its position. On January 2, 2020, Spire Missouri submitted Applications for Transfer to the Missouri Supreme Court. The MoPSC also submitted Applications for Transfer to the Missouri Supreme Court that advanced similar positions as Spire Missouri. The submission of the Applications will stay the effectiveness of the ISRS rulings pending the outcome of the Missouri Supreme Court’s decision whether to accept these rulings for review. If the Missouri Supreme Court decides not to review the lower court rulings, the cases would be remanded to the MoPSC, who would then define its process to review the facts and evidence supporting its earlier approval and determine the appropriate process to determine the appropriate refund, if any, that may be required.

Spire Missouri has recorded an estimate of the maximum impact of the ISRS rulings based on its interpretation of the rulings and evidence available. As of September 30, 2019, Spire Missouri recorded an estimated $12.2 regulatory liability for this matter by reducing revenue for fiscal year 2019. There were two components of this provision. The first related to a $4.2 refund ordered by the ISRS rulings for amounts collected prior to the last rate case, after which recoveries of related authorized revenues became part of base rates that went into effect in April 2018. The second component related to an estimate of $8.0 for revenues associated with the June 2018 ISRS filing that was approved by the MoPSC effective October 8, 2018. In the first quarter of fiscal 2020, an additional provision of $2.1 was recorded to the regulatory liability for ISRS revenues related to customer billings recorded during the quarter under this 2018 filing, along with a $0.5 provision for interest due on the entirety of the ISRS revenues in dispute if refunded. The after-tax impact of the first quarter provisions reduced net income by $2.0, which is excluded for the net economic earnings financial measure. In future periods, Spire Missouri will evaluate the need for an adjustment to the provisions based upon new information and further developments.

Similar appeals by both the Company and OPC are with the Missouri Western District Court of Appeals for the ISRS filings in both January 2019 and July 2019.

In January 2020, legislation was introduced in both the Missouri House and Senate to clarify language in the statute governing ISRS mechanism.  Specifically, the bills seek to ensure we can continue to upgrade our infrastructure, enhance its safety and reliability, and secure timely recovery of costs incurred.

As part of their annual updates for RSE, on November 25, 2019, Spire Alabama and Spire Gulf filed an increase for rate year 2020 of $5.9 and $1.6, respectively, which became effective December 1, 2019. In addition, Spire Alabama was granted authority to begin an off-system sales and capacity release sharing program similar to the program currently in place at Spire Missouri.

On November 21, 2019, the Federal Energy Regulatory Commission (FERC) issued an Order on Rehearing of its August 3, 2018 order issuing a certificate of public convenience and necessity to Spire STL Pipeline LLC. In the Order on Rehearing, the FERC dismissed or denied the outstanding requests for rehearing filed by several parties, dismissed the request for stay filed by one party and noted the withdrawal of the request for rehearing by another party. On January 21, 2020, two of the rehearing parties timely filed petitions for review of the FERC’s orders with the Court of Appeals for the District of Columbia Circuit.

12. LEASES

The lease agreement covering the Company’s primary office space in St. Louis extends through February 2035, with an option to renew for an additional five years. Spire Alabama currently has leased office space in two buildings in Birmingham; one lease expires in 2020 and the other extends through January 2024. The lease agreement covering Spire Marketing and Spire Storage office space in Houston extends through December 2028, with options to terminate three years earlier or to renew for an additional five years. The St. Louis and Houston renewals are reasonably certain and are included in the lease term used to determine the right-of use assets and lease liabilities. The Company and its subsidiaries have other relatively minor rental arrangements for real estate and equipment with remaining terms of up to eleven years.

Operating lease cost, cash flow and noncash information for the three months ended December 31, 2019 are shown in the following table.

	Spire		Spire Missouri		Spire Alabama

As of September 30, 2019, the annual minimum rental commitments for operating leases (under ASC 840) were as follows.

	2020		2021		2022		2023		2024		Later		Total

Spire Missouri		0.5		0.2		—		—		—		—		0.7
Spire Alabama		2.9		2.1		2.1		2.1		0.7		—		9.9

There are no significant finance leases, short-term leases, subleases, variable lease payments, residual value guarantees, restrictions or covenants pertaining to leases.

The Company elected, for all asset classes, not to recognize right-of-use assets and lease liabilities for short-term leases. Instead, the lease payments are recognized in profit or loss on a straight-line basis over the lease term and variable lease payments are recognized in the period in which the obligation for those payments is incurred. The Company elected, for all asset classes, not to separate nonlease components from lease components and instead to account for each separate lease component and the nonlease components associated with that lease component as a single lease component.

The discount rate used for all the leases is the applicable incremental borrowing rate, which is the rate of interest that a lessee would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. For a subsidiary lessee, the rate applicable to the subsidiary is used unless the lease terms are influenced by parent credit.

Fair Value Assets And Liabilities Measured On Recurring And Nonrecurring Basis [Line Items]

Schedule of Fair Value Assets and Liabilities Measured on Recurring Basis

The information presented below categorizes the assets and liabilities in the balance sheets that are accounted for at fair value on a recurring basis in periods subsequent to initial recognition.

The mutual funds included in Level 1 are valued based on exchange-quoted market prices of individual securities.

Derivative instruments included in Level 1 are valued using quoted market prices on the New York Mercantile Exchange (NYMEX) or the Intercontinental Exchange (ICE). Derivative instruments classified in Level 2 include physical commodity derivatives that are valued using broker or dealer quotation services whose prices are derived principally from, or are corroborated by, observable market inputs. Also included in Level 2 are certain derivative instruments that have values that are similar to, and correlate with, quoted prices for exchange-traded instruments in active markets. Derivative instruments included in Level 3 are valued using generally unobservable inputs that are based upon the best information available and reflect management’s assumptions about how market participants would price the asset or liability. The Level 3 balances as of December 31, 2019, September 30, 2019, and December 31, 2018, consisted of gas commodity contracts. The Company’s and the Utilities’ policy is to recognize transfers between the levels of the fair value hierarchy, if any, as of the beginning of the interim reporting period in which circumstances change or events occur to cause the transfer.

The mutual funds are included in “Other Investments” on the Company’s balance sheets and in “Other Property and Investments” on Spire Missouri’s balance sheets. Derivative assets and liabilities, including receivables and payables associated with cash margin requirements, are presented net in the balance sheets when a legally enforceable netting agreement exists between the Company, Spire Missouri, or Spire Alabama and the counterparty to a derivative contract.

Commitments And Contingencies Disclosure [Abstract]

Commitments and Contingencies

11. COMMITMENTS AND CONTINGENCIES

Commitments

The Company and the Utilities have entered into contracts with various counterparties, expiring on dates through 2032, for the storage, transportation, and supply of natural gas. Minimum payments required under the contracts in place at December 31, 2019, are estimated at $1,554.6, $690.3, and $239.3 for the Company, Spire Missouri, and Spire Alabama, respectively. Additional contracts are generally entered into prior to or during the heating season of November through April. The Utilities recover their costs from customers in accordance with their PGA clauses or GSA riders.

Contingencies

The Company and the Utilities account for contingencies, including environmental liabilities, in accordance with accounting standards under the loss contingency guidance of ASC Topic 450, Contingencies, when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

In addition to matters noted below, the Company and the Utilities are involved in other litigation, claims, and investigations arising in the normal course of business. Management, after discussion with counsel, believes the final outcome will not have a material effect on the statements of income, balance sheets, and statements of cash flows of the Company, Spire Missouri, or Spire Alabama. However, there is uncertainty in the valuation of pending claims and prediction of litigation results.

The Company and the Utilities own and operate natural gas distribution, transmission, and storage facilities, the operations of which are subject to various environmental laws, regulations, and interpretations. While environmental issues resulting from such operations arise in the ordinary course of business, such issues have not materially affected the Company’s or Utilities’ financial position and results of operations. As environmental laws, regulations, and their interpretations change, the Company or the Utilities may incur additional environmental liabilities that may result in additional costs, which may be material.

In the natural gas industry, many gas distribution companies have incurred environmental liabilities associated with sites they or their predecessor companies formerly owned or operated where manufactured gas operations took place. The Utilities each have former manufactured gas plant (MGP) operations in their respective service territories. To the extent costs are incurred associated with environmental remediation activities, the Utilities would request authority from their respective regulators to defer such costs (less any amounts received from insurance proceeds or as contributions from other potentially responsible parties (PRPs)) and collect them through future rates.

Spire Missouri

Spire Missouri has identified three former MGP sites in the city of St. Louis, Missouri (the “City”) where costs have been incurred and claims have been asserted. Spire Missouri has enrolled two of the sites in the Missouri Department of Natural Resources (MDNR) Brownfields/Voluntary Cleanup Program (BVCP). The third site is the result of a relatively new claim assertion by the United States Environmental Protection Agency (EPA).

In conjunction with redevelopment of one of the sites, Spire Missouri and another former owner of the site entered into an agreement (the “Remediation Agreement”) with the City development agencies, the developer, and an environmental consultant that obligates one of the City agencies and the environmental consultant to remediate the site and obtain a No Further Action letter from the MDNR. The Remediation Agreement also provides for a release of Spire Missouri and the other former site owner from certain liabilities related to the past and current environmental condition of the site and requires the developer and the environmental consultant to maintain certain insurance coverage, including remediation cost containment, premises pollution liability, and professional liability. The operative provisions of the Remediation Agreement were triggered on December 20, 2010, on which date Spire Missouri and the other former site owner, as full consideration under the Remediation Agreement, paid a small percentage of the cost of remediation of the site. The amount paid by Spire Missouri did not materially impact the financial condition, results of operations, or cash flows of the Company.

Spire Missouri has not owned the second site for many years. In a letter dated June 29, 2011, the Attorney General for the State of Missouri informed Spire Missouri that the MDNR had completed an investigation of the site. The Attorney General requested that Spire Missouri participate in the follow up investigations of the site. In a letter dated January 10, 2012, Spire Missouri stated that it would participate in future environmental response activities at the site in conjunction with other PRPs that are willing to contribute to such efforts in a meaningful and equitable fashion. Accordingly, Spire Missouri entered into a cost sharing agreement for remedial investigation with other PRPs. To date, MDNR has not approved the agreement, so remedial investigation has not yet occurred.

Additionally, in correspondence dated November 30, 2016, Region 7 of the EPA has asserted that Spire Missouri is liable under Section 107(a) of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) for alleged coal gas waste contamination at a third site in the northern portion of the City on which Spire Missouri operated a MGP. Spire Missouri has not owned or operated the site (also known as Station “B”) for over 70 years. Spire Missouri and the site owner have met with the EPA and reviewed its assertions. Both Spire Missouri and the site owner have notified the EPA that information and data provided by the EPA to date does not rise to the level of documenting a threat to the public health or environment. As such, Spire Missouri requested more information from the EPA, some of which would also be utilized to identify other former owners and operators of the site that could be added as PRPs. To date, Spire Missouri has not received a response from the EPA.

Spire Missouri has notified its insurers that it seeks reimbursement for costs incurred in the past and future potential liabilities associated with these MGP sites. While some of the insurers have denied coverage and reserved their rights, Spire Missouri retains the right to seek potential reimbursements from them.

On March 10, 2015, Spire Missouri received a Section 104(e) information request under CERCLA from EPA Region 7 regarding the former Thompson Chemical/Superior Solvents site in the City. In turn, Spire Missouri issued a Freedom of Information Act (FOIA) request to the EPA on April 3, 2015, in an effort to identify the basis of the inquiry. The FOIA response from the EPA was received on July 15, 2015 and a response was provided to the EPA on August 15, 2015. Spire Missouri has received no further inquiry from the EPA regarding this matter.

In its western service area, Spire Missouri has seven owned MGP sites enrolled in the BVCP, including Joplin MGP #1, St. Joseph MGP #1, Kansas City Coal Gas Station B, Kansas City Station A Railroad area, Kansas City Coal Gas Station A North, Kansas City Coal Gas Station A South, and Independence MGP #2. Source removal has been conducted at all of the owned sites since 2003 with the exception of Joplin. On September 15, 2016, a request was made with the MDNR for a restrictive covenant use limitation with respect to Joplin. Remediation efforts at the seven sites are at various stages of completion, ranging from groundwater monitoring and sampling following source removal activities to the aforementioned request in respect to Joplin. As part of its participation in the BVCP, Spire Missouri communicates regularly with the MDNR with respect to its remediation efforts and monitoring activities at these sites. On May 11, 2015, MDNR approved the next phase of investigation at the Kansas City Station A North and Railroad areas.

To date, costs incurred for all Missouri Utilities’ MGP sites for investigation, remediation and monitoring these sites have not been material. However, the amount of costs relative to future remedial actions at these and other sites is unknown and may be material. The actual future costs that Spire Missouri may incur could be materially higher or lower depending upon several factors, including whether remediation actions will be required, final selection and regulatory approval of any remedial actions, changing technologies and government regulations, the ultimate ability of other PRPs to pay, and any insurance recoveries.

In 2013, Spire Missouri retained an outside consultant to conduct probabilistic cost modeling of 19 former MGP sites owned or operated by Spire Missouri. The purpose of this analysis was to develop an estimated range of probabilistic future liability for each site. That analysis, completed in August 2014, provided a range of demonstrated possible future expenditures to investigate, monitor and remediate all 19 MGP sites. Spire Missouri has recorded its best estimate of the probable expenditures that relate to these matters. The amount is not material.

Spire Missouri and the Company do not expect potential liabilities that may arise from remediating these sites to have a material impact on their future financial condition or results of operations.

Spire Alabama

Spire Alabama is in the chain of title of nine former MGP sites, four of which it still owns, and five former manufactured gas distribution sites, one of which it still owns. Spire Alabama does not foresee a probable or reasonably estimable loss associated with these sites. Spire Alabama and the Company do not expect potential liabilities that may arise from remediating these sites to have a material impact on their future financial condition or results of operations.

In 2012, Spire Alabama responded to an EPA Request for Information Pursuant to Section 104 of CERCLA relating to the 35th Avenue Superfund Site located in North Birmingham, Jefferson County, Alabama. Spire Alabama was identified as a PRP under CERCLA for the cleanup of the site or costs the EPA incurs in cleaning up the site. At this point, Spire Alabama has not been provided information that would allow it to determine the extent, if any, of its potential liability with respect to the 35th Avenue Superfund Site and vigorously denies its inclusion as a PRP.

Spire

In addition to those discussed above for Spire Missouri and Spire Alabama, Spire is aware of the following contingent matter.

In February 2018, the Company was made aware of a complaint filed with the U.S. Department of Housing and Urban Development (HUD) by the South Alabama Center for Fair Housing and the National Community Reinvestment Coalition. The complaint alleges that the Company discriminated against unspecified residents of Eight Mile, Alabama, on the basis of race in violation of the Fair Housing Act by failing to adequately address the odorant release that occurred in 2008. The Company believes there is no basis for the complaint, HUD has no jurisdiction in the matter, and there will be no material impact on its future financial condition or results of operations.

Fair Value Disclosures [Abstract]

Fair Value Measurements

7. FAIR VALUE MEASUREMENTS

The information presented below categorizes the assets and liabilities in the balance sheets that are accounted for at fair value on a recurring basis in periods subsequent to initial recognition.

The mutual funds included in Level 1 are valued based on exchange-quoted market prices of individual securities.

Derivative instruments included in Level 1 are valued using quoted market prices on the New York Mercantile Exchange (NYMEX) or the Intercontinental Exchange (ICE). Derivative instruments classified in Level 2 include physical commodity derivatives that are valued using broker or dealer quotation services whose prices are derived principally from, or are corroborated by, observable market inputs. Also included in Level 2 are certain derivative instruments that have values that are similar to, and correlate with, quoted prices for exchange-traded instruments in active markets. Derivative instruments included in Level 3 are valued using generally unobservable inputs that are based upon the best information available and reflect management’s assumptions about how market participants would price the asset or liability. The Level 3 balances as of December 31, 2019, September 30, 2019, and December 31, 2018, consisted of gas commodity contracts. The Company’s and the Utilities’ policy is to recognize transfers between the levels of the fair value hierarchy, if any, as of the beginning of the interim reporting period in which circumstances change or events occur to cause the transfer.

The mutual funds are included in “Other Investments” on the Company’s balance sheets and in “Other Property and Investments” on Spire Missouri’s balance sheets. Derivative assets and liabilities, including receivables and payables associated with cash margin requirements, are presented net in the balance sheets when a legally enforceable netting agreement exists between the Company, Spire Missouri, or Spire Alabama and the counterparty to a derivative contract.

Accounting Policies [Abstract]

Basis of Presentation

BASIS OF PRESENTATION – These notes are an integral part of the accompanying unaudited financial statements of Spire Inc. (“Spire” or the “Company”) presented on a consolidated basis, Spire Missouri Inc. (“Spire Missouri” or the “Missouri Utilities”) and Spire Alabama Inc. (“Spire Alabama”). Spire Missouri and Spire Alabama are wholly owned subsidiaries of Spire. Spire Missouri, Spire Alabama and the subsidiaries of Spire EnergySouth Inc. (“Spire EnergySouth”) are collectively referred to as the “Utilities.” The subsidiaries of Spire EnergySouth are Spire Gulf Inc. and Spire Mississippi Inc.

The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information with the instructions to Form 10-Q and Rule 10-01 of Regulation S‑X. Accordingly, they do not include all the disclosures required for complete financial statements. In the opinion of management, the accompanying unaudited financial statements include all adjustments (consisting of only normal recurring adjustments) necessary for the fair presentation of the results of operations for the periods presented. This Form 10-Q should be read in conjunction with the Notes to Financial Statements contained in Spire’s, Spire Missouri’s and Spire Alabama’s combined Annual Report on Form 10-K for the fiscal year ended September 30, 2019.

The consolidated financial position, results of operations, and cash flows of Spire include the accounts of the Company and all its subsidiaries. Transactions and balances between consolidated entities have been eliminated from the consolidated financial statements of Spire. In compliance with GAAP, transactions between Spire Missouri and Spire Alabama and their affiliates, as well as intercompany balances on their balance sheets, have not been eliminated from their separate financial statements.

Derivatives

DERIVATIVES – In the course of their business, certain subsidiaries of Spire enter into commitments associated with the purchase or sale of natural gas. Certain of their derivative natural gas contracts are designated as normal purchases or normal sales and, as such, are excluded from the scope of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 815, Derivatives and Hedging. Those contracts are accounted for as executory contracts and recorded on an accrual basis. Revenues and expenses from such contracts are recorded gross. Contracts not designated as normal purchases or normal sales are recorded as derivatives with changes in fair value recognized in earnings in the periods prior to physical delivery. Certain of Spire Marketing’s wholesale purchase and sale transactions are classified as trading activities for financial reporting purposes. Under GAAP, revenues and expenses associated with trading activities are presented on a net basis in Gas Marketing operating revenues (or expenses, if negative) in the Condensed Consolidated Statements of Income. This net presentation has no effect on operating income or net income.

Regulated Operations

REGULATED OPERATIONS – The Utilities account for their regulated operations in accordance with FASB ASC Topic 980, Regulated Operations. This topic sets forth the application of GAAP for those companies whose rates are established by or are subject to approval by an independent third-party regulator. The provisions of this accounting guidance require, among other things, that financial statements of a regulated enterprise reflect the actions of regulators, where appropriate. These actions may result in the recognition of revenues and expenses in time periods that are different than non-regulated enterprises. When this occurs, costs are deferred as assets in the balance sheet (regulatory assets) and recorded as expenses when those amounts are reflected in rates. In addition, regulators can impose liabilities upon a regulated company for amounts previously collected from customers and for recovery of costs that are expected to be incurred in the future (regulatory liabilities). Management believes that the current regulatory environment supports the continued use of these regulatory accounting principles and that all regulatory assets and regulatory liabilities are recoverable or refundable through the regulatory process.

As authorized by the Missouri Public Service Commission (MoPSC), the Mississippi Public Service Commission (MSPSC) and the Alabama Public Service Commission (APSC), the Purchased Gas Adjustment (PGA) clauses and Gas Supply Adjustment (GSA) riders allow the Utilities to pass through to customers the cost of purchased gas supplies. Regulatory assets and liabilities related to the PGA clauses and the GSA riders are both labeled Unamortized Purchased Gas Adjustments herein. See additional information about regulatory assets and liabilities in Note 4, Regulatory Matters.

Transactions with Affiliates

TRANSACTIONS WITH AFFILIATES – Transactions between affiliates of the Company have been eliminated from the consolidated financial statements of Spire. Spire Missouri and Spire Alabama borrowed funds from the Company and incurred related interest, as reflected in their separate financial statements, and they participated in normal intercompany shared services transactions. In addition, Spire Missouri’s other transactions with affiliates are presented in the table below:

	Three Months Ended December 31,
	2019		2018
Purchases of natural gas from Spire Marketing Inc.	$	19.5	$	39.8
Transportation services received from Spire STL Pipeline LLC		3.9		—
Sales of natural gas to Spire Marketing Inc.		—		1.4
Transportation services received from Spire NGL Inc.		0.3		0.3

In the quarter ended December 31, 2019, Spire Alabama had purchases of natural gas from Spire Marketing totaling $3.3.

Accrued Capital Expenditures

ACCRUED CAPITAL EXPENDITURES – Accrued capital expenditures, shown in the following table, are excluded from capital expenditures in the statements of cash flows until paid.

	December 31,		September 30,		December 31,
	2019		2019		2018
Spire	$	45.8	$	80.6	$	46.2
Spire Missouri		20.2		40.1		18.1
Spire Alabama		9.8		11.9		9.7

New Accounting Pronouncements

NEW ACCOUNTING PRONOUNCEMENTS – Spire, Spire Missouri and Spire Alabama adopted Accounting Standards Update (ASU) No. 2016-02, Leases, along with related ASU Nos. 2018-01, 2018-10, 2018-11, 2018-20 and 2019-01 (collectively, “ASC 842”) using a modified retrospective transition method for leases existing at, or entered into after, October 1, 2019. Under the selected transition method, comparative periods in the financial statements are presented under ASC 840 (previous lease accounting guidance). ASC 842 requires lessees to recognize a right-of-use asset and lease liability for almost all lease contracts based on the present value of lease payments. It provides new guidelines for identifying and classifying a lease, and classification affects the pattern and income statement line item for the related expense. The Company and its subsidiaries elected a package of three practical expedients permitted by the standard, allowing them not to reassess existing contracts for (1) whether it is or contains a lease, (2) lease classification and (3) initial direct costs. They also elected to use the benefit of hindsight in determining both the lease term and impairments associated with any existing leases, which resulted in lease terms that best represent management’s expectations with respect to use of the underlying asset but did not result in recognition of any impairment. Finally, they elected not to assess whether existing land easements are leases under ASC 842. The adoption of ASC 842 impacted the balance sheets through recognition of right-of-use assets and lease liabilities for operating leases but did not result in a cumulative effect adjustment or significant impacts to income or cash flows. For other lease policy elections and disclosures about leases, see Note 12, Leases.

Spire, Spire Missouri and Spire Alabama adopted the guidance in ASU No. 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities, and related ASU Nos. 2018-16, 2019-04, and 2019-10 in the first quarter of fiscal year 2020. The amendments in this ASU more closely align the results of hedge accounting with risk management activities through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results in the financial statements. They did not have a significant impact on the financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments, which was later supplemented by ASU Nos. 2018-19, 2019-04, 2019-05 and 2019-11. The standard introduces new guidance for the accounting for credit losses on instruments within its scope, including trade receivables. It is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The new guidance will be initially applied through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. Spire, Spire Missouri and Spire Alabama are currently assessing the impacts of adopting this standard, which must be adopted by the first quarter of fiscal 2021.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION – These notes are an integral part of the accompanying unaudited financial statements of Spire Inc. (“Spire” or the “Company”) presented on a consolidated basis, Spire Missouri Inc. (“Spire Missouri” or the “Missouri Utilities”) and Spire Alabama Inc. (“Spire Alabama”). Spire Missouri and Spire Alabama are wholly owned subsidiaries of Spire. Spire Missouri, Spire Alabama and the subsidiaries of Spire EnergySouth Inc. (“Spire EnergySouth”) are collectively referred to as the “Utilities.” The subsidiaries of Spire EnergySouth are Spire Gulf Inc. and Spire Mississippi Inc.

The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information with the instructions to Form 10-Q and Rule 10-01 of Regulation S‑X. Accordingly, they do not include all the disclosures required for complete financial statements. In the opinion of management, the accompanying unaudited financial statements include all adjustments (consisting of only normal recurring adjustments) necessary for the fair presentation of the results of operations for the periods presented. This Form 10-Q should be read in conjunction with the Notes to Financial Statements contained in Spire’s, Spire Missouri’s and Spire Alabama’s combined Annual Report on Form 10-K for the fiscal year ended September 30, 2019.

The consolidated financial position, results of operations, and cash flows of Spire include the accounts of the Company and all its subsidiaries. Transactions and balances between consolidated entities have been eliminated from the consolidated financial statements of Spire. In compliance with GAAP, transactions between Spire Missouri and Spire Alabama and their affiliates, as well as intercompany balances on their balance sheets, have not been eliminated from their separate financial statements.

NATURE OF OPERATIONS – Spire has two reportable segments: Gas Utility and Gas Marketing. The Gas Utility segment consists of the regulated natural gas distribution operations of the Company and is the core business segment of Spire in terms of revenue and earnings. The Gas Utility segment is comprised of the operations of: the Missouri Utilities, serving St. Louis and eastern Missouri (“Spire Missouri East”) and Kansas City and western Missouri (“Spire Missouri West”); Spire Alabama, serving central and northern Alabama; and the subsidiaries of Spire EnergySouth, serving southern Alabama and south-central Mississippi. The Gas Marketing segment includes Spire’s primary gas-related business, Spire Marketing Inc. (“Spire Marketing”), which provides non-regulated natural gas services, primarily in the central and southern United States (U.S.). The activities of other subsidiaries are reported as Other and are described in Note 10, Information by Operating Segment. Spire Missouri and Spire Alabama each have a single reportable segment.

Nearly all the Company’s earnings are derived from its Gas Utility segment. Due to the seasonal nature of the Utilities’ business and the Spire Missouri rate design, earnings are typically concentrated during the heating season of November through April each fiscal year. As a result, the interim statements of income for Spire, Spire Missouri and Spire Alabama are not necessarily indicative of annual results or representative of succeeding quarters of the fiscal year.

DERIVATIVES – In the course of their business, certain subsidiaries of Spire enter into commitments associated with the purchase or sale of natural gas. Certain of their derivative natural gas contracts are designated as normal purchases or normal sales and, as such, are excluded from the scope of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 815, Derivatives and Hedging. Those contracts are accounted for as executory contracts and recorded on an accrual basis. Revenues and expenses from such contracts are recorded gross. Contracts not designated as normal purchases or normal sales are recorded as derivatives with changes in fair value recognized in earnings in the periods prior to physical delivery. Certain of Spire Marketing’s wholesale purchase and sale transactions are classified as trading activities for financial reporting purposes. Under GAAP, revenues and expenses associated with trading activities are presented on a net basis in Gas Marketing operating revenues (or expenses, if negative) in the Condensed Consolidated Statements of Income. This net presentation has no effect on operating income or net income.

REGULATED OPERATIONS – The Utilities account for their regulated operations in accordance with FASB ASC Topic 980, Regulated Operations. This topic sets forth the application of GAAP for those companies whose rates are established by or are subject to approval by an independent third-party regulator. The provisions of this accounting guidance require, among other things, that financial statements of a regulated enterprise reflect the actions of regulators, where appropriate. These actions may result in the recognition of revenues and expenses in time periods that are different than non-regulated enterprises.

As authorized by the Missouri Public Service Commission (MoPSC), the Mississippi Public Service Commission (MSPSC) and the Alabama Public Service Commission (APSC), the Purchased Gas Adjustment (PGA) clauses and Gas Supply Adjustment (GSA) riders allow the Utilities to pass through to customers the cost of purchased gas supplies. Regulatory assets and liabilities related to the PGA clauses and the GSA riders are both labeled Unamortized Purchased Gas Adjustments herein. See additional information about regulatory assets and liabilities in Note 4, Regulatory Matters.

TRANSACTIONS WITH AFFILIATES – Transactions between affiliates of the Company have been eliminated from the consolidated financial statements of Spire. Spire Missouri and Spire Alabama borrowed funds from the Company and incurred related interest, as reflected in their separate financial statements, and they participated in normal intercompany shared services transactions. In addition, Spire Missouri’s other transactions with affiliates are presented in the table below:

NEW ACCOUNTING PRONOUNCEMENTS – Spire, Spire Missouri and Spire Alabama adopted Accounting Standards Update (ASU) No. 2016-02, Leases, along with related ASU Nos. 2018-01, 2018-10, 2018-11, 2018-20 and 2019-01 (collectively, “ASC 842”) using a modified retrospective transition method for leases existing at, or entered into after, October 1, 2019.

Pension Plans and Other Postretirement Benefits

9. PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

Pension Plans

Spire and the Utilities maintain pension plans for their employees.

The Missouri Utilities have non-contributory, defined benefit, trusteed forms of pension plans covering the majority of their employees. Plan assets consist primarily of corporate and U.S. government obligations and a growth segment consisting of exposure to equity markets, commodities, real estate and inflation-indexed securities, achieved through derivative instruments.

Spire Alabama has non-contributory, defined benefit, trusteed forms of pension plans covering the majority of its employees. Qualified plan assets are comprised of mutual and commingled funds consisting of U.S. equities with varying strategies, global equities, alternative investments, and fixed income investments.

The net periodic pension cost included the following components:

* Denotes pension expense line items that are recorded below the operating income line in the income statements, in the line item “Other Income (Expense), Net.”

Pursuant to the provisions of the Missouri Utilities’ and Spire Alabama’s pension plans, pension obligations may be satisfied by monthly annuities, lump-sum cash payments, or special termination benefits. Lump-sum payments are recognized as settlements (which can result in gains or losses) only if the total of such payments exceeds the sum of service and interest costs in a specific year. Special termination benefits, when offered, are also recognized as settlements which can result in gains or losses. For the first quarter of both fiscal 2020 and fiscal 2019, no pension plans met the criteria for settlement recognition.      

The funding policy of the Utilities is to contribute an amount not less than the minimum required by government funding standards, nor more than the maximum deductible amount for federal income tax purposes. Fiscal 2020 contributions to Spire Missouri’s pension plans through December 31, 2019 were $4.1 to the qualified trusts and none to non-qualified plans. There were $1.6 of fiscal 2020 contributions to the Spire Alabama pension plans through December 31, 2019.

Contributions to the qualified trusts of the Missouri Utilities’ pension plans for the remainder of fiscal 2020 are anticipated to be $24.9. Contributions to Spire Alabama’s pension plans are expected to be $11.5 for the remainder of fiscal 2020.

Other Postretirement Benefits

Spire and the Utilities provide certain life insurance benefits at retirement. Spire Missouri plans provide for medical insurance after early retirement until age 65. For retirements prior to January 1, 2015, the Spire Missouri West plans provided medical insurance after retirement until death. The Spire Alabama plans provide medical insurance upon retirement until death for certain retirees depending on the type of employee and the date the employee was originally hired.

Net periodic postretirement benefit costs consisted of the following components:

Missouri and Alabama state laws provide for the recovery in rates of costs accrued pursuant to GAAP provided that such costs are funded through an independent, external funding mechanism. The Utilities have established Voluntary Employees’ Beneficiary Association (VEBA) and Rabbi Trusts as external funding mechanisms. The assets of the VEBA and Rabbi Trusts consist primarily of money market securities and mutual funds invested in stocks and bonds.

The Utilities’ funding policy is to contribute amounts to the trusts equal to the periodic benefit cost calculated pursuant to GAAP as recovered in rates. There have been no contributions to the postretirement plans through December 31, 2019 for the Missouri Utilities or Spire Alabama, and none are expected to be required for the remainder of the fiscal year.

Segment Reporting [Abstract]

Information by Operating Segment

10. INFORMATION BY OPERATING SEGMENT

The Company has two reportable segments: Gas Utility and Gas Marketing. The Gas Utility segment is the aggregation of the operations of the Utilities. The Gas Marketing segment includes the results of Spire Marketing, a subsidiary engaged in the non-regulated marketing of natural gas and related activities, including utilizing natural gas storage contracts for providing natural gas sales. Other components of the Company’s consolidated information include:

• unallocated corporate items, including certain debt and associated interest costs;

• Spire STL Pipeline, a subsidiary of Spire which has constructed and, as of November 2019, operates a 65-mile FERC-regulated pipeline to deliver natural gas into eastern Missouri;

• Spire Storage, a subsidiary of Spire providing physical natural gas storage services; and

• Spire’s subsidiaries engaged in the operation of a propane pipeline, the compression of natural gas, and risk management, among other activities.

Accounting policies are described in Note 1, Summary of Significant Accounting Policies. Intersegment transactions include sales of natural gas from Spire Marketing to Spire Missouri and Spire Alabama, sales of natural gas from Spire Missouri to Spire Marketing, propane transportation services provided by Spire NGL Inc. to Spire Missouri, and propane storage services provided by Spire Missouri to Spire NGL Inc.

Management evaluates the performance of the operating segments based on the computation of net economic earnings. Net economic earnings exclude from reported net income the after-tax impacts of fair value accounting and timing adjustments associated with energy-related transactions, the impacts of acquisition, divestiture and restructuring activities, and the largely non-cash impacts of other non-recurring or unusual items such as certain regulatory, legislative, or GAAP standard-setting actions. In fiscal 2020, this includes provisions for the ISRS rulings discussed in Note 4, Regulatory Matters.

Fair Value of Financial Instruments

6. FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amounts and estimated fair values of financial instruments not measured at fair value on a recurring basis are shown in the following tables, classified according to the fair value hierarchy. There were no such instruments classified as Level 3 (significant unobservable inputs) as of December 31, 2019, September 30, 2019, or December 31, 2018.

The carrying amounts of cash and cash equivalents and short-term debt approximate fair value due to the short maturity of these instruments. The fair values of long-term debt are estimated based on market prices for similar issues. Refer to Note 7, Fair Value Measurements, for information on financial instruments measured at fair value on a recurring basis.
