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), as well as Laclede Gas Company (Laclede Gas or the Missouri Utilities) and Alabama Gas Corporation (Alagasco). Laclede Gas, which includes the operations of Missouri Gas Energy (MGE), and Alagasco are wholly owned subsidiaries of the Company. Laclede Gas, Alagasco and the subsidiaries of EnergySouth, Inc. (EnergySouth) are collectively referred to as the Utilities. The subsidiaries of EnergySouth are Mobile Gas Service Corporation (Mobile Gas) and Willmut Gas & Oil Company (Willmut Gas).

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 of 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, Laclede Gas’, and Alagasco’s Annual Reports on Form 10-K for the fiscal year ended September 30, 2016.

The consolidated financial position, results of operations, and cash flows of Spire are primarily derived from the financial position, results of operations, and cash flows of the Utilities. In compliance with GAAP, transactions between Laclede Gas and Alagasco and their affiliates, as well as intercompany balances on their balance sheets, have not been eliminated from their separate financial statements. Spire’s September 12, 2016 acquisition of EnergySouth are included in the results of operations since the acquisition and impact the comparability of financial statement periods presented for the Company.

NATURE OF OPERATIONS – Spire Inc. (NYSE: SR), headquartered in St. Louis, Missouri, is a public utility holding company. The Company 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 generation. The Gas Utility segment is comprised of the operations of: the Missouri Utilities, serving St. Louis and eastern Missouri, Kansas City and western Missouri (through MGE); Alagasco, serving central and northern Alabama; and the subsidiaries of EnergySouth, serving southern Alabama and south-central Mississippi. Spire’s primary non-utility business, Spire Marketing Inc. (Spire Marketing) was formerly known as Laclede Energy Resources, Inc., which changed its name on December 12, 2016. Spire Marketing is included in the Gas Marketing segment and provides non-regulated natural gas services. The activities of other subsidiaries are described in Note 9, Information by Operating Segment, and are reported as Other. Laclede Gas and Alagasco each have a single reportable segment.

The Company’s earnings are primarily derived from its Gas Utility segment. Due to the seasonal nature of the Utilities’ business, 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, Laclede Gas and Alagasco are not necessarily indicative of annual results or representative of succeeding quarters of the fiscal year.

GOODWILL – Goodwill is measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. The changes in the carrying amount of goodwill by reportable segment are shown below, reflecting the effect of a $3.8 cash payment to Spire related to the EnergySouth acquisition, offset by immaterial adjustments to assets acquired.



	Gas Utility		Gas Marketing		Other			Total
Balance as of September 30, 2016	$	210.2	$	—	$	954.7		$	1,164.9
Adjustments related to the acquisition of EnergySouth	—		—		(3.5		)	(3.5		)
Balance as of December 31, 2016	$	210.2	$	—	$	951.2		$	1,161.4

REVENUE RECOGNITION – The Utilities read meters and bill customers on monthly cycles. The Missouri Utilities record their gas utility revenues from gas sales and transportation services on an accrual basis that includes estimated amounts for gas delivered but not yet billed. The accruals for unbilled revenues are reversed in the subsequent accounting period when meters are actually read and customers are billed. The amounts of accrued unbilled revenues for Laclede Gas at December 31, 2016, September 30, 2016, and December 31, 2015 were $103.5, $26.1, and $74.6, respectively.

Alagasco records natural gas distribution revenues in accordance with the tariff established by the Alabama Public Service Commission (APSC). Unbilled revenues for Alagasco, which are not recorded as revenue until billed, at December 31, 2016, September 30, 2016, and December 31, 2015 were $22.0, $5.9, and $16.4, respectively.

The subsidiaries of EnergySouth record natural gas revenues in accordance with tariffs established by the APSC and the Mississippi Public Service Commission (MSPSC). Their unbilled revenues are accrued as described for Laclede Gas above.

Spire’s other subsidiaries, including Spire Marketing, record revenues when earned, either when the product is delivered or when services are performed.

In the course of its business, Spire Marketing enters 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 using a gross presentation. 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 in the Condensed Consolidated Statements of Income. This net presentation has no effect on operating income or net income.

GROSS RECEIPTS TAXES – Gross receipts taxes associated with the Company’s natural gas utility services are imposed on the Utilities and billed to their customers. The revenue and expense amounts are recorded gross in the “Operating Revenues” and “Taxes, other than income taxes” lines, respectively, in the statements of income. The following table presents gross receipts taxes recorded as revenues.



	Three Months Ended December 31,
	2016		2015
Spire	$	19.4	$	17.9
Laclede Gas	14.1		13.9
Alagasco	4.2		4.0

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), MSPSC and 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 rider are both labeled Unamortized Purchased Gas Adjustments herein. See additional information about regulatory assets and liabilities in Note 3, Regulatory Matters.

TRANSACTIONS WITH AFFILIATES – Transactions between affiliates of the Company have been eliminated from the consolidated financial statements of Spire. Other than borrowings from Spire reflected in Alagasco’s Condensed Balance Sheets and Condensed Statements of Cash Flows and normal intercompany shared services transactions, there were no transactions between Alagasco and affiliates during the three months ended December 31, 2016 and December 31, 2015. Laclede Gas’ transactions with affiliates included:



	Three Months Ended December 31,
	2016		2015
Purchases of natural gas from Spire Marketing	$	20.5	$	13.2
Sales of natural gas to Spire Marketing	3.6		0.7
Transportation services received from Laclede Pipeline Company	0.3		0.3
Insurance services received from Laclede Insurance Risk Services	1.1		0.2

UTILITY PLANT – Laclede Gas had accrued capital expenditures of $6.8, $14.8, and $4.6 as of December 31, 2016, September 30, 2016, and December 31, 2015, respectively. Alagasco had accrued capital expenditures of $5.6, $6.8, and $3.1 as of December 31, 2016, September 30, 2016, and December 31, 2015, respectively. Accrued capital expenditures are excluded from the capital expenditures shown in the statements of cash flows.

FINANCING RECEIVABLES – Alagasco finances third-party contractor sales of merchandise including gas furnaces and appliances, and related financing receivables totaled approximately $11.8, $11.8, and $11.2 as of December 31, 2016, September 30, 2016, and December 31, 2015, respectively. Financing is available only to qualified customers who meet creditworthiness thresholds for customer payment history and external agency credit reports. Alagasco relies upon ongoing payments as the primary indicator of credit quality during the term of each contract. The allowance for credit losses is recognized using an estimate of write-off percentages based on historical experience applied to an aging of the financing receivable balance. Delinquent accounts are evaluated on a case-by-case basis and, absent evidence of debt repayment after 90 days, are due in full and assigned to a third-party collection agency. The remaining financing receivable is written off approximately 12 months after being assigned to the third-party collection agency. Alagasco’s financing receivables that were at least 90 days past due totaled $0.4 as of December 31, 2016, September 30, 2016, and December 31, 2015. Alagasco recorded corresponding reserves for credit losses at each of those dates. Mobile Gas also finances customer purchases of gas heating and cooling systems, but related financing receivables are not material.

RECLASSIFICATIONS – Certain prior period amounts have been reclassified to conform to the current period presentation. Net income and total equity were not affected by these reclassifications.

NEW ACCOUNTING PRONOUNCEMENT – In April 2015, the FASB issued Accounting Standards Update (ASU) No. 2015-03, Interest – Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs. Under prior GAAP, debt issuance costs were recorded as a deferred charge (asset), while debt discount and debt premium costs were recorded as a liability adjustment. This amendment requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The Company, Laclede Gas and Alagasco adopted this ASU as of December 31, 2016, and retrospectively adjusted the comparative balance sheets as of September 30, 2016 and December 31, 2015. The amounts reclassified from other deferred charges to reduce long-term debt are shown in the following table. The ASU does not address the presentation of debt issuance costs related to line-of-credit arrangements, and those continue to be reported as deferred charges.



	December 31, 2016		September 30, 2016		December 31, 2015
Spire	$	12.5	$	13.0	$	12.6
Laclede Gas	4.1		4.2		4.6
Alagasco	2.3		2.4		2.4
