Accounting Policies [Abstract] | |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION – These notes are an integral part of the accompanying audited financial statements of Spire Inc. presented on a consolidated basis (Spire or the Company), 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 the Company. Spire Missouri changed its name from Laclede Gas Company on August 30, 2017, and Spire Alabama changed its name from Alabama Gas Corporation on September 1, 2017. Spire Missouri, Spire Alabama and the subsidiaries of Spire EnergySouth Inc. (formerly known as EnergySouth, Inc.) are collectively referred to as the Utilities. The subsidiaries of Spire EnergySouth Inc. (Spire EnergySouth) are Spire Gulf Inc. (Spire Gulf, formerly known as Mobile Gas Service Corporation) and Spire Mississippi Inc. (Spire Mississippi, formerly known as Willmut Gas & Oil Company). The accompanying audited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). Unless otherwise indicated, references to years herein are references to the fiscal years ending September 30 for the Company and its subsidiaries. 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 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. The Company’s September 12, 2016 acquisition of Spire EnergySouth is included in the results of operations since the acquisition date and impacts the comparability of the financial statement periods presented for the Company. For a further discussion of the acquisition, see Note 2 , Acquisitions. The Utilities are regulated natural gas distribution utilities. Due to the seasonal nature of the Utilities, the earnings of Spire, Spire Missouri and Spire Alabama are typically concentrated during the heating season of November through April each fiscal year. NATURE OF OPERATIONS – Spire Inc. (NYSE: SR) is a public utility holding company with principal offices in St. Louis, Missouri. 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 (Spire Missouri East) and Kansas City and western Missouri (Spire Missouri West, formerly Missouri Gas Energy, or MGE); Spire Alabama, serving central and northern Alabama; and the subsidiaries of Spire EnergySouth, serving southern Alabama and south-central Mississippi. Spire’s primary non-utility business, Spire Marketing Inc. (Spire Marketing), included in the Gas Marketing segment, provides non-regulated natural gas services. The activities of other subsidiaries are described in Note 14 , Information by Operating Segment, and are reported as Other. Spire Missouri and Spire Alabama each have a single reportable segment. USE OF ESTIMATES – The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. SYSTEM OF ACCOUNTS – The accounts of the Utilities are maintained in accordance with the Uniform System of Accounts prescribed by the applicable state public service commissions, which systems substantially conform to that prescribed by the Federal Energy Regulatory Commission (FERC). PROPERTY, PLANT, AND EQUIPMENT – Utility Plant – Utility plant is stated at original cost. The cost of additions to utility plant includes contracted work, direct labor and materials, allocable overheads, and an allowance for funds used during construction. The costs of units of property retired, replaced, or renewed are removed from utility plant and are charged to accumulated depreciation. Maintenance and repairs of property and replacement and renewal of items determined to be less than units of property are charged to maintenance expenses. For Spire Missouri, utility plant is depreciated on a straight-line basis at rates based on estimated service lives of the various classes of property. In fiscal years 2017 , 2016 and 2015 , annual depreciation and amortization expense averaged 3.0% of the original cost of depreciable and amortizable property. For Spire Alabama, depreciation is provided using the composite method of depreciation on a straight-line basis over the estimated useful lives of utility property at rates approved by the Alabama Public Service Commission (APSC). The composite depreciation rate is approximately 3.1% . Non-utility Property – Non-utility property is recorded at the original cost of acquisition or construction, which includes material, labor, contractor services and, for FERC-regulated projects, an allowance for funds used during construction. Repairs, replacements and renewals of items of property determined to be less than a unit of property or that do not increase the property’s life or functionality are charged to maintenance expense. Upon retirement or sale of non-utility property, the original cost and related accumulated depreciation are removed from the accounts and any gain or loss is included in the income statements. Costs related to software developed or obtained for internal use are capitalized and amortized on a straight-line basis over the estimated useful life of the related software. If software is retired prior to being fully amortized, the difference is recorded as a loss in the income statements. Accrued Capital Expenditures – Accrued capital expenditures, shown in the following table, are excluded from capital expenditures in the statements of cash flows. September 30 2017 2016 2015 Spire $ 41.0 $ 30.4 $ 13.4 Spire Missouri 28.9 14.8 9.6 Spire Alabama 9.4 6.8 3.1 ASSET RETIREMENT OBLIGATIONS – Spire, Spire Missouri, and Spire Alabama record legal obligations associated with the retirement of long-lived assets in the period in which the obligations are incurred, if sufficient information exists to reasonably estimate the fair value of the obligations. Obligations are recorded as both a cost of the related long-lived asset and as a corresponding liability. Subsequently, the asset retirement costs are depreciated over the life of the asset and the asset retirement obligations are accreted to the expected settlement amounts. The Company, Spire Missouri and Spire Alabama record asset retirement obligations associated with certain safety requirements to purge and seal gas distribution mains upon retirement, the plugging and abandonment of storage wells and other storage facilities, specific service line obligations, and certain removal and disposal obligations related to components of Spire Missouri’s, Spire Alabama’s and Spire Gulf’s distribution systems and general plant. Asset retirement obligations recorded by Spire’s other subsidiaries are not material. As authorized by the Missouri Public Service Commission (MoPSC) and APSC, Spire Missouri, Spire Alabama and Spire Gulf accrue future asset removal costs associated with their property, plant and equipment even if a legal obligation does not exist. Such accruals are provided for through depreciation expense and are recorded with corresponding credits to regulatory liabilities or regulatory assets. When those utilities retire depreciable utility plant and equipment, they charge the associated original costs to accumulated depreciation and amortization, and any related removal costs incurred are charged to regulatory liabilities or regulatory assets. The difference between removal costs recognized in depreciation rates and the accretion expense and depreciation expense recognized for financial reporting purposes is a timing difference between recovery of these costs in rates and their recognition for financial reporting purposes. Accordingly, these differences are deferred as regulatory liabilities or regulatory assets. In the rate setting process, the regulatory liabilities or regulatory assets are excluded from the rate base upon which those utilities have the opportunity to earn their allowed rates of return. The costs associated with asset retirement obligations of Spire Missouri, Spire Alabama and Spire Gulf are either currently being recovered in rates or are probable of recovery in future rates. The following table presents a reconciliation of the beginning and ending balances of asset retirement obligations at September 30, as reported in the balance sheets. Spire Spire Missouri Spire Alabama 2017 2016 2017 2016 2017 2016 Asset retirement obligations, beginning of year $ 206.4 $ 159.2 $ 75.2 $ 72.4 $ 120.1 $ 86.6 Liabilities incurred during the period 5.5 4.1 0.3 1.2 5.2 2.9 Liabilities settled during the period (4.6 ) (9.5 ) (1.1 ) (1.9 ) (1.9 ) (6.8 ) Accretion 9.1 13.2 3.6 3.5 5.0 9.7 Revisions in estimated cash flows 80.2 27.5 80.6 — — 27.7 Addition of Spire EnergySouth asset retirement obligations — 11.9 — — — — Asset retirement obligations, end of year $ 296.6 $ 206.4 $ 158.6 $ 75.2 $ 128.4 $ 120.1 REGULATED OPERATIONS – The Utilities account for their regulated operations in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (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. See additional discussion on regulated operations in Note 15 , Regulatory Matters. As discussed below for Spire Missouri and Spire Alabama, 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 regulatory liabilities related to the PGA clauses and the GSA rider are both labeled Unamortized Purchased Gas Adjustments herein. Spire Missouri As authorized by the MoPSC, the PGA clause allows Spire Missouri to flow through to customers, subject to prudence review by the MoPSC, the cost of purchased gas supplies. To better match customer billings with market natural gas prices, Spire Missouri is allowed to file to modify, on a periodic basis, the level of gas costs in its PGA. Certain provisions of the PGA clause are included below: • Spire Missouri has a risk management policy that allows for the purchase of natural gas derivative instruments with the goal of managing price risk associated with purchasing natural gas on behalf of its customers. The MoPSC clarified that costs, cost reductions, and carrying costs associated with the Utility’s use of natural gas derivative instruments are gas costs recoverable through the PGA mechanism. • The tariffs allow Spire Missouri flexibility to make up to three discretionary PGA changes during each year, in addition to its mandatory November PGA change, so long as such changes are separated by at least two months . • Spire Missouri is authorized to apply carrying costs to all over- or under-recoveries of gas costs, including costs and cost reductions associated with the use of derivative instruments, including cash payments for margin deposits. Spire Missouri East is also authorized to recover gas inventory carrying costs through its PGA rates to recover costs it incurs to finance its investment in gas supplies that are purchased during the storage injection season for sale during the heating season. • The MoPSC approved a plan applicable to Spire Missouri’s gas supply commodity costs under which it retains a portion of cost savings associated with the acquisition of natural gas below an established benchmark level. This gas supply cost management program allows Spire Missouri to retain 10% of cost savings, up to a maximum of $3.0 annually. Spire Missouri did not record any such incentive compensation under the plan during the three fiscal years reported. Incentives recorded under the plan, if any, are included in Gas Utility Operating Revenues on the Consolidated Statements of Income and under Operating Revenues on Spire Missouri’s Statements of Income. Pursuant to the provisions of the PGA clause, the difference between actual costs incurred and costs recovered through the application of the PGA clause are reflected as a deferred charge or credit at the end of the fiscal year. These costs include costs and cost reductions associated with the use of derivative instruments and gas inventory carrying costs, amounts due to or from customers related to operation of the gas supply cost management program, refunds received from the Company’s suppliers in connection with gas supply, transportation, and storage services, and carrying costs on such over- or under-recoveries. At that time, the balance is classified as a current asset or current liability and recovered from, or credited to, customers over an annual period commencing in November. The balance in the current account is amortized as amounts are reflected in customer billings. The PGA clause also provides for the treatment of income from off-system sales and capacity release revenues. Pre-tax income from off-system sales and capacity release revenues is shared with customers, with an estimated amount assumed in PGA rates. The difference between the actual amount allocated to customers for each fiscal year and the estimated amount assumed in PGA rates is recovered from, or credited to, customers over an annual period commencing in the subsequent November. The customer share of such income is determined in accordance with the following tables, shown for each service territory for which the PGA clauses were approved by the MoPSC. Customer Share Company Share Spire Missouri East First $2.0 of pre-tax income* 85% 15% Next $2.0 of pre-tax income 80% 20% Next $2.0 of pre-tax income 75% 25% Amounts of pre-tax income exceeding $6.0 70% 30% * Customer share was set to 85% and company share set to 15% in fiscal 2017. For fiscal 2016 and 2015, the customer share and company share were 100% and 0%, respectively. Spire Missouri West First $1.2 of pre-tax income 85% 15% Next $1.2 of pre-tax income 80% 20% Next $1.2 of pre-tax income 75% 25% Amounts of pre-tax income exceeding $3.6 70% 30% Spire Alabama Spire Alabama’s rate schedules for natural gas distribution charges contain a GSA rider, established in 1993, which permits the pass-through to customers of changes in the cost of gas supply. Spire Alabama’s tariff provides a temperature adjustment mechanism, also included in the GSA rider, which is designed to moderate the impact of departures from normal temperatures on Spire Alabama’s earnings. The temperature adjustment applies primarily to residential, small commercial and small industrial customers. Other non-temperature weather-related conditions that may affect customer usage are not included in the temperature adjustment. NATURAL GAS AND PROPANE GAS – For Spire Missouri East, inventory of natural gas in storage is priced on a last in, first out (LIFO) basis and inventory of propane gas in storage is priced on a first in, first out (FIFO) basis. For the rest of the Gas Utility segment, inventory of natural gas in storage is priced on the weighted average cost basis. The replacement cost of Spire Missouri’s natural gas for current use in eastern Missouri at September 30, 2017 and September 30, 2016 was less than the LIFO cost by $20.8 and $11.4 , respectively. The carrying value of the Utilities’ inventory is not adjusted to the lower of cost or market prices because, pursuant to PGA or GSA, actual gas costs are recovered in customer rates. Natural gas and propane gas storage inventory in Spire’s other operating segments is recorded at the lower of average cost or market. BUSINESS COMBINATIONS – The Spire EnergySouth acquisition was accounted for by Spire using business combination accounting. Under this method, the purchase price paid by the acquirer is allocated to the assets acquired and liabilities assumed as of the acquisition date based on their fair value. For additional information on the acquisition of Spire EnergySouth, refer to Note 2 , Acquisitions. 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. Spire and Spire Missouri evaluate goodwill for impairment as of July 1 of each year, or more frequently if events and circumstances indicate that goodwill might be impaired. At July 1, 2017, 2016 and 2015, Spire and Spire Missouri each applied a quantitative goodwill evaluation model to their reporting units and concluded goodwill was not impaired because the fair value exceeded the carrying amount. The changes in the carrying amount of goodwill by reportable segment were as follows: Gas Utility Gas Marketing Other Total Balance as of September 30, 2014 $ 210.2 $ — $ 727.6 $ 937.8 Adjustments to finalize the acquisition of Spire Alabama — — 8.2 8.2 Balance as of September 30, 2015 210.2 — 735.8 946.0 Acquisition of Spire EnergySouth — — 218.9 218.9 Balance as of September 30, 2016 210.2 — 954.7 1,164.9 Adjustments to finalize the acquisition of Spire EnergySouth — — 6.7 6.7 Balance as of September 30, 2017 $ 210.2 $ — $ 961.4 $ 1,171.6 IMPAIRMENT OF LONG-LIVED ASSETS – Long-lived assets classified as held and used are evaluated for impairment when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. Whether impairment has occurred is determined by comparing the estimated undiscounted cash flows attributable to the assets with the carrying value of the assets. If the carrying value exceeds the undiscounted cash flows, the Company recognizes an impairment charge equal to the amount of the carrying value that exceeds the estimated fair value of the assets. In the period in which the Company determines an asset meets held-for-sale criteria, an impairment charge is recorded to the extent the book value exceeds its fair value less cost to sell. REVENUE RECOGNITION – The Utilities read meters and bill customers on monthly cycles. The Missouri Utilities, Spire Gulf and Spire Mississippi 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 Spire Missouri at September 30, 2017 and 2016 were $30.1 and $26.1 , respectively. Spire Alabama records natural gas distribution revenues in accordance with the tariff established by the APSC. Unbilled revenue is accrued in an amount equal to the related gas cost, as profit margin is not considered earned until billed. The amounts of accrued unbilled revenues for Spire Alabama at September 30, 2017 and 2016 were $1.9 and $5.9 . 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 its derivative natural gas contracts are designated as normal purchases or normal sales and, as such, are excluded from the scope of 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. For additional information on derivative instruments, refer to Note 10 , Derivative Instruments and Hedging Activities. 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 Consolidated Statements of Income. This net presentation has no effect on operating income or net income. INCOME TAXES – Spire and its subsidiaries account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amount of existing assets and liabilities and the respective tax basis and for tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effects on deferred tax assets and liabilities of a change in enacted tax rates is recognized in income or loss for a non-regulated company, and in a regulatory asset or regulatory liability for a regulated company. A valuation allowance is established when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company accounts for uncertain tax positions in accordance with authoritative guidance. The authoritative guidance addresses the determination of whether tax benefits claimed, or expected to be claimed, on a tax return should be recorded in the financial statements. Spire may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the position will be sustained upon examination by the taxing authority, based on the technical merits of the position. Tax-related interest and penalties, if any, are classified as a liability on the balance sheets. CASH AND CASH EQUIVALENTS – All highly liquid debt instruments purchased with original maturities of three months or less are considered to be cash equivalents. Such instruments are carried at cost, which approximates market value. Outstanding checks on the Company’s and Utilities’ bank accounts in excess of funds on deposit create book overdrafts (which are funded at the time checks are presented for payment) and are classified as Other in the Current Liabilities section of the balance sheets. Changes in book overdrafts are reflected as Operating Activities in the statements of cash flows. NATURAL GAS RECEIVABLE – Spire Marketing enters into natural gas transactions with natural gas pipeline companies known as park and loan arrangements. Under the terms of the arrangements, Spire Marketing purchases natural gas from a third party and delivers that natural gas to the pipeline company for the right to receive the same quantity of natural gas from the pipeline company at the same location in a future period. These arrangements are accounted for as non-monetary transactions under GAAP and are recorded at the carrying amount. As such, natural gas receivables are reflected on the Consolidated Balance Sheets at cost, which includes related pipeline fees associated with the transactions. In the period that the natural gas is returned to Spire Marketing, concurrent with the sale of the natural gas to a third party, the related natural gas receivable is expensed in the Consolidated Statements of Income. In conjunction with these transactions, Spire Marketing usually enters into New York Mercantile Exchange (NYMEX) and Intercontinental Exchange (ICE) natural gas futures, options, and swap contracts or fixed price sales agreements to protect against market changes in future sales prices. EARNINGS PER COMMON SHARE – GAAP requires dual presentation of basic and diluted earnings per share (EPS). EPS is computed using the two-class method, which is an earnings allocation method for computing EPS that treats a participating security as having rights to earnings that would otherwise have been available to common shareholders. Certain of the Company’s stock-based compensation awards pay non-forfeitable dividends to the participants during the vesting period and, as such, are deemed participating securities. Basic EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding that are increased for additional shares that would be outstanding if potentially dilutive non-participating securities were converted to common shares, pursuant to the treasury stock method. Shares attributable to equity units, non-participating stock options and time-vested restricted stock/units are excluded from the calculation of diluted earnings per share if the effect would be antidilutive. Shares attributable to non-participating performance-contingent restricted stock awards are only included in the calculation of diluted earnings per share to the extent the underlying performance and/or market conditions are satisfied (a) prior to the end of the reporting period or (b) would be satisfied if the end of the reporting period were the end of the related contingency period and the result would be dilutive. The Company’s EPS computations are presented in Note 4 , Earnings Per Common Share. GROSS RECEIPTS AND SALES TAXES – Gross receipts taxes associated with the Company’s natural gas utility services are imposed on the Company, Spire Missouri, and Spire Alabama and billed to its 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: 2017 2016 2015 Spire $ 84.6 $ 75.5 $ 97.3 Spire Missouri 60.7 57.4 74.5 Spire Alabama 19.5 17.9 22.6 Sales taxes imposed on applicable Spire Alabama and Spire Missouri sales are billed to customers. These amounts are not recorded in the statements of income but are recorded as tax collections payable and included in the “Other” line of the Current Liabilities section of the balance sheets. 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 participated in normal intercompany shared services transactions. In addition, Spire Missouri’s other transactions with affiliates included: 2017 2016 2015 Purchases of natural gas from Spire Marketing $ 74.4 $ 46.3 $ 74.1 Sales of natural gas to Spire Marketing 7.8 1.9 4.0 Transportation services received from Spire NGL Inc. 1.0 1.0 1.0 ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS – Trade accounts receivable are recorded at the amounts due from customers, including unbilled amounts. Estimates of the collectability of trade accounts receivable are based on historical trends, age of receivables, economic conditions, credit risk of specific customers, and other factors. Accounts receivable are written off against the allowance for doubtful accounts when they are deemed to be uncollectible. Spire’s provision for uncollectible accounts includes the amortization of previously deferred uncollectible expenses for Spire Missouri and Spire Alabama, as approved by the MoPSC and the APSC, respectively. FINANCE RECEIVABLES – Spire Alabama finances third party contractor sales of merchandise including gas furnaces and appliances. At September 30, 2017 and September 30, 2016 , the Company’s finance receivable totaled approximately $12.5 and $11.8 , respectively. Financing is available only to qualified customers who meet creditworthiness thresholds for customer payment history and external agency credit reports. Spire Alabama 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 finance 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 finance receivable is written off approximately 12 months after being assigned to the third-party collection agency. Spire Alabama had finance receivables past due 90 days or more of $0.4 at September 30, 2017 and September 30, 2016 . Spire Alabama recorded a related allowance for credit losses at September 30, 2017 and September 30, 2016 of $0.4 . GROUP MEDICAL AND WORKERS’ COMPENSATION RESERVES – The Company self-insures its group medical and workers’ compensation costs and carries stop-loss coverage in relation to medical claims and workers’ compensation claims. Reserves for amounts incurred but not reported are established based on historical cost levels and lags between occurrences and reporting. FAIR VALUE MEASUREMENTS – Certain assets and liabilities are recognized or disclosed at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). GAAP establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The levels of the hierarchy are described below: • Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2 – Pricing inputs other than quoted prices included within Level 1, which are either directly or indirectly observable for the asset or liability as of the reporting date. These inputs are derived principally from, or corroborated by, observable market data. • Level 3 – Pricing that is based upon inputs that are generally unobservable that are based on the best information available and reflect management’s assumptions about how market participants would price the asset or liability. Assessment of the significance of a particular input to the fair value measurements may require judgment and may affect the valuation of the asset or liability and its placement within the fair value hierarchy. Additional information about fair value measurements is provided in Note 8 , Fair Value of Financial Instruments, Note 9 , Fair Value Measurements, and Note 13 , Pension Plans and Other Postretirement Benefits. STOCK-BASED COMPENSATION – The Company measures stock-based compensation awards at fair value at the date of grant and recognizes the compensation cost of the awards over the requisite service period. Effective with the adoption of Accounting Standards Update No. 2016-09 at the beginning of fiscal 2017 (described under New Accounting Pronouncements below), forfeitures are recognized in the period they occur. In fiscal 2016 and fiscal 2015, forfeitures were estimated at the time of grant and revised, when necessary, in subsequent periods when the actu |

ACQUISITIONS | ACQUISITIONS Effective September 12, 2016, Spire completed the acquisition of 100% of the common stock of Spire EnergySouth, the parent company of Spire Gulf and Spire Mississippi, serving natural gas utility customers in Alabama and Mississippi. This acquisition is supportive of the strategic focus on growing Spire’s gas utility business and creating geographic and regulatory diversity. Total cash consideration paid, net of cash acquired, debt assumed, and a working capital settlement payment received, was $313.9 . The goodwill of $225.6 arising from this acquisition, which is not deductible for tax purposes, is attributable to the assembled workforce and the expected cost efficiencies and strategic benefits of the transaction. The Company did not elect pushdown accounting, so the goodwill was recorded on the Spire parent company balance sheet rather than the Spire EnergySouth subsidiary balance sheet and is included in disclosures of segment assets under Other. The following table summarizes the consideration paid and the amounts of the assets acquired and liabilities assumed at the acquisition date. As originally recorded Measurement period adjustments As adjusted Recognized amounts of identifiable assets acquired and liabilities assumed: Utility plant $ 199.5 $ — $ 199.5 Cash 2.0 — 2.0 Other current assets 17.5 0.2 17.7 Other assets 79.8 (10.7 ) 69.1 Long-term debt (67.0 ) — (67.0 ) Other current liabilities (42.7 ) — (42.7 ) Deferred tax liabilities (35.5 ) — (35.5 ) Other liabilities (52.8 ) — (52.8 ) Total identifiable net assets 100.8 (10.5 ) 90.3 Goodwill 218.9 6.7 225.6 Consideration (cash) $ 319.7 $ (3.8 ) $ 315.9 Spire EnergySouth’s results of operations are included in the Spire statements of income from the date of acquisition, as shown in the following table. 2017 2016 Total Operating Revenues $ 95.5 $ 3.3 Net Income (Loss) 9.4 (0.2 ) Earnings Per Share $ 0.20 $ — The following unaudited pro forma financial information presents Spire’s combined results of operations as though the Spire EnergySouth acquisition had occurred as of the beginning of fiscal 2015.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |
STOCK-BASED COMPENSATION | STOCK-BASED COMPENSATION Spire’s 2015 incentive plan, The Laclede Group 2015 Equity Incentive Plan (the 2015 Plan), was approved at the annual meeting of shareholders of Spire on January 29, 2015. The purpose of the 2015 Plan is to encourage directors, officers, and employees of the Company and its subsidiaries to contribute to the Company’s success and align their interests with that of shareholders. To accomplish this purpose, the Compensation Committee (Committee) of the Board of Directors may grant awards under the 2015 Plan that may be earned by achieving performance objectives and/or other criteria as determined by the Committee. Under the terms of the 2015 Plan, officers and employees of the Company and its subsidiaries, as determined by the Committee, are eligible to be selected for awards. The 2015 Plan provides for restricted stock, restricted stock units, qualified and non-qualified stock options, stock appreciation rights, and performance shares payable in stock, cash, or a combination of both. The 2015 Plan generally provides a minimum vesting period of at least three years for each type of award, with pro rata vesting permitted during the minimum three -year vesting period. The maximum number of shares reserved for issuance under the 2015 Plan is 1,000,000 . The 2015 Plan replaced The Laclede Group 2006 Equity Incentive Plan (the 2006 Plan), which in turn replaced The Laclede Group, Inc. 2002 Equity Incentive Plan (the 2002 Plan). Shares reserved under the 2006 Plan and the 2002 Plan, other than those needed for outstanding awards, were canceled upon shareholder approval of the 2015 Plan. The Company issues new shares to satisfy employee restricted stock awards and stock option exercises. Restricted Stock Awards During fiscal 2017 , the Company granted 196,400 performance-contingent restricted share units to executive officers and key employees at a weighted average grant date fair value of $45.01 per share. This number represents the maximum shares that can be earned pursuant to the terms of the awards. The share units have a performance period ending September 30, 2019. While the participants have no interim voting rights on these share units, dividends accrue during the performance period and are paid to the participants upon vesting, but are subject to forfeiture if the underlying share units do not vest. The number of share units that will ultimately vest is dependent upon the attainment of certain levels of earnings and other strategic goals, as well as the Company’s level of total shareholder return (TSR) during the performance period relative to a comparator group of companies. This TSR provision is considered a market condition under GAAP and is discussed further below. The weighted average grant date fair value of performance-contingent restricted shares and share units granted during fiscal years 2016 and 2015 was $45.95 and $36.69 per share, respectively. Fiscal 2017 activity of restricted stock and restricted stock units subject to performance and/or market conditions is presented below: Shares/ Units Weighted Average Grant Date Fair Value Per Share Nonvested at September 30, 2016 510,583 $ 40.37 Granted (maximum shares that can be earned) 196,400 $ 45.01 Vested (78,825 ) $ 42.37 Forfeited (64,128 ) $ 33.03 Nonvested at September 30, 2017 (at maximum) 564,030 $ 42.51 Nonvested at September 30, 2017 (at target) 282,015 $ 56.32 During fiscal 2017 , the Company granted 33,240 shares of time-vested restricted stock to executive officers and key employees at a weighted average grant date fair value of $63.05 per share. Unless forfeited based on terms of the agreements, these shares will vest in fiscal 2020. In the interim, participants receive full voting rights and dividends, which are not subject to forfeiture. The weighted average grant date fair value of time-vested restricted stock and restricted stock units awarded to employees during fiscal years 2016 and 2015 was $59.40 and $50.90 per share, respectively. During fiscal 2017 , the Company granted 10,850 shares of time-vested restricted stock to non-employee directors at a weighted average grant date fair value of $63.45 per share. These shares vested in fiscal 2017, six months after the grant date. The weighted average grant date fair value of restricted stock awarded to non-employee directors during fiscal years 2016 and 2015 was $63.93 and $54.66 per share, respectively. Time-vested restricted stock and stock unit activity for fiscal 2017 is presented below: Shares/ Units Weighted Average Grant Date Fair Value Per Share Nonvested at September 30, 2016 132,779 $ 49.83 Granted 44,090 $ 63.15 Vested (58,200 ) $ 47.67 Forfeited (7,729 ) $ 55.58 Nonvested at September 30, 2017 110,940 $ 55.85 For restricted stock and stock units (performance-contingent and time-vested) that vested during fiscal years 2017, 2016, and 2015, the Company withheld 35,514 shares, 30,712 shares, and 31,688 , respectively, at weighted average prices of $63.83 , $57.29 , and $50.65 per share, respectively, pursuant to elections by employees to satisfy tax withholding obligations. The total fair value of restricted stock (performance-contingent and time-vested) that vested during fiscal years 2017 , 2016 , and 2015 was $8.9 , $6.3 , and $6.4 , respectively, and the related tax benefit was $3.3 , $2.4 , and $2.4 , respectively. None of the tax benefits have been realized. Stock Option Awards No stock options were granted during fiscal years 2017 , 2016 , and 2015 . There was no stock option activity in fiscal 2017, as all outstanding stock options either vested or forfeited in fiscal 2016. During fiscal 2016 , cash received from the exercise of stock options was $0.7 and the related intrinsic value was $0.7 . During fiscal 2015 , cash received from the exercise of stock options was $1.5 and the related intrinsic value was $0.9 . Related tax benefits were not material in any of those years. Equity Compensation Costs Compensation cost for performance-contingent restricted stock and stock unit awards is based upon the probable outcome of the performance conditions. For shares or units that do not vest or that are not expected to vest due to the outcome of the performance conditions (excluding market conditions), no compensation cost is recognized and any previously recognized compensation cost is reversed. The fair value of awards of performance-contingent and time-vested restricted stock and restricted stock units, not subject to the TSR provision, are estimated using the closing price of the Company’s stock on the grant date. For those awards that do not pay dividends during the vesting period, the estimate of fair value is reduced by the present value of the dividends expected to be paid on the Company’s common stock during the performance period, discounted using an appropriate United States (US) Treasury yield. For shares subject to the TSR provision, the estimated impact of this market condition is reflected in the grant date fair value per share of the awards. Accordingly, compensation cost is not reversed to reflect any actual reductions in the awards that may result from the TSR provision. However, if the Company’s TSR during the performance period ranks below the level specified in the award agreements, relative to a comparator group of companies, and the Committee elects not to reduce the award (or reduce by a lesser amount), this election would be accounted for as a modification of the original award and additional compensation cost would be recognized at that time. The grant date fair value of the awards subject to the TSR provision awarded during fiscal years 2017 , 2016 , and 2015 was valued by a Monte Carlo simulation model that assessed the probabilities of various TSR outcomes. The significant assumptions used in the Monte Carlo simulations are as follows: 2017 2016 2015 Risk-free interest rate 1.39% 1.14% 0.83% Expected dividend yield of stock — — — Expected volatility of stock 16.3% 15.0% 14.0% Vesting period 2.8 years 2.8 years 2.8 years The risk-free interest rate was based on the yield on US Treasury securities matching the vesting period. A zero percent dividend yield was used, which is mathematically equivalent to the assumption that dividends are reinvested as they are paid. The expected volatility is based on the historical volatility of the Company’s stock. Volatility assumptions were also made for each of the companies included in the comparator group. The vesting period is equal to the performance period set forth in the terms of the award. The amounts of compensation cost recognized for share-based compensation arrangements are presented below: 2017 2016 2015 Total compensation cost $ 7.4 $ 6.7 $ 6.7 Compensation cost capitalized (3.3 ) (2.2 ) (1.8 ) Compensation cost recognized in net income $ 4.1 $ 4.5 $ 4.9 Income tax benefit recognized in net income (1.5 ) (1.7 ) (1.9 ) Compensation cost recognized in net income, net of income tax $ 2.6 $ 2.8 $ 3.0 As of September 30, 2017 , there was $8.9 of total unrecognized compensation cost related to non-vested share-based compensation arrangements. That cost is expected to be recognized over a weighted average period of 1.8 years . |

Stockholders' Equity Note [Abstract] | |
STOCKHOLDERS' EQUITY | SHAREHOLDERS’ EQUITY Spire In 2014, Spire issued 2.875 million equity units as a portion of the Spire Alabama acquisition financing. The equity units were originally issued at $50 per unit pursuant to the Purchase Contract and Pledge Agreement (Purchase Contract) dated as of June 11, 2014 between Spire and U.S. Bank National Association, as purchase contract agent, collateral agent, custodial agent and securities intermediary. These units consisted of $143.8 aggregate principal amount of 2014 Series A 2.00% remarketable junior subordinated notes due 2022 and the Purchase Contract obligating the holder to purchase common shares at a future settlement date. The equity unit investments were effectively replaced as planned in a series of transactions outlined in Note 6 , resulting in the issuance of 2,504,684 shares of the Company’s common stock at a purchase price of $57.3921 per share. Under the contract terms, the equity units were converted to common stock at the rate of 0.8712 shares per unit, with a corresponding adjustment to purchase price. Spire filed a registration statement on Form S-3 with the US Securities and Exchange Commission (SEC) on June 15, 2017 for the issuance and sale of up to 250,000 shares of its common stock under its Dividend Reinvestment and Direct Stock Purchase Plan. There were 244,130 and 239,945 shares at September 30, 2017 and November 10, 2017 , respectively, remaining available for issuance under this Form S-3. On May 17, 2016, Spire completed a public offering of 2,185,000 shares of its common stock, generating $133.2 of proceeds net of issuance costs. On September 23, 2016, Spire and Spire Missouri filed with the SEC a joint shelf registration statement on Form S-3 for issuance of various types of debt and equity securities, which registration statement will expire September 22, 2019. The amount, timing, and type of additional financing to be issued under this shelf registration statement will depend on cash requirements and market conditions. At September 30, 2017 and 2016 , Spire had authorized 5,000,000 shares of preferred stock, but none were issued and outstanding. Spire Missouri Substantially all of Spire Missouri’s plant is subject to the liens of its first mortgage bonds. The mortgage contains several restrictions on Spire Missouri’s ability to pay cash dividends on its common stock or to make loans to its parent company. These mortgage restrictions are applicable regardless of whether the stock is publicly held or held solely by Spire Missouri’s parent company. Under the most restrictive of these provisions, no cash dividend may be declared or paid if, after the dividend, the aggregate net amount spent for all dividends after September 30, 1953 would exceed a maximum amount determined by a formula set out in the mortgage. Under that formula, the maximum amount is the sum of $8.0 plus earnings applicable to common stock (adjusted for stock repurchases and issuances) for the period from September 30, 1953 to the last day of the quarter before the declaration or payment date for the dividends. As of September 30, 2017 and 2016 , the amount under the mortgage’s formula that was available to pay dividends was $1,010.8 and $916.8 , respectively. Thus, all of Spire Missouri’s retained earnings were free from such dividend restrictions as of those dates. On September 23, 2016, Spire and Spire Missouri filed with the SEC a joint shelf registration statement on Form S-3 for issuance of various types of debt and equity securities, which registration statement will expire September 22, 2019. The amount, timing, and type of additional financing to be issued under this shelf registration statement will depend on cash requirements and market conditions, as well as future MoPSC authorizations. Spire Missouri has authority from the MoPSC to issue debt securities and preferred stock, including on a private placement basis, as well as to issue common stock, receive paid-in capital, and enter into capital lease agreements, all for a total of up to $300.0 . On September 15, 2017, Spire Missouri issued $170.0 in first mortgage bonds, leaving $130.0 available under the MoPSC authorization. At September 30, 2017 and 2016 , Spire Missouri had authorized 1,480,000 shares of preferred stock, but none were issued and outstanding. Spire Alabama At September 30, 2017 and 2016 , Spire Alabama had authorized 120,000 shares of preferred stock, but none were issued and outstanding. Other Comprehensive Income The components of accumulated other comprehensive income (loss), net of income taxes, recognized in the balance sheets at September 30 were as follows: Net Unrealized Gains (Losses) on Cash Flow Hedges Defined Benefit Pension and Other Postretirement Benefit Plans Net Unrealized Losses on Available for Sale Securities Total Spire Balance at September 30, 2015 $ (0.4 ) $ (1.5 ) $ (0.1 ) $ (2.0 ) Other comprehensive loss (1.9 ) (0.3 ) — (2.2 ) Balance at September 30, 2016 (2.3 ) (1.8 ) (0.1 ) (4.2 ) Other comprehensive income (loss) 7.2 0.3 (0.1 ) 7.4 Balance at September 30, 2017 $ 4.9 $ (1.5 ) $ (0.2 ) $ 3.2 Spire Missouri Balance at September 30, 2015 (0.2 ) (1.5 ) — $ (1.7 ) Other comprehensive income (loss) 0.3 (0.3 ) (0.1 ) (0.1 ) Balance at September 30, 2016 0.1 (1.8 ) (0.1 ) (1.8 ) Other comprehensive income (loss) — 0.2 (0.1 ) 0.1 Balance at September 30, 2017 $ 0.1 $ (1.6 ) $ (0.2 ) $ (1.7 ) Income tax expense (benefit) recorded for items of other comprehensive income (loss) reported in the statements of comprehensive income is calculated by applying statutory federal, state, and local income tax rates applicable to ordinary income. The tax rates applied to individual items of other comprehensive income (loss) are similar within each reporting period. For the periods presented, Spire Alabama had no accumulated other comprehensive income (loss) balances. |

Debt Disclosure [Abstract] | |
LONG-TERM DEBT | LONG-TERM DEBT Composition of long-term debt for Spire, Spire Missouri and Spire Alabama are shown in each registrant’s statements of capitalization as part of the financial statements. Maturities of long-term debt for Spire on a consolidated basis, Spire Missouri and Spire Alabama for the five fiscal years subsequent to September 30, 2017 are as follows: Spire Spire Missouri Spire Alabama 2018 $ 100.0 $ 100.0 $ — 2019 180.0 50.0 — 2020 40.0 — 40.0 2021 55.0 — — 2022 50.0 — 50.0 Spire’s, Spire Missouri’s and Spire Alabama’s short-term credit facilities and long-term debt agreements contain customary covenants and default provisions. As of September 30, 2017 , there were no events of default under these covenants. 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. The credit ratings of the Company, Spire Missouri and Spire Alabama remain at investment grade, but are subject to review and change by the rating agencies. 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. Spire On March 10, 2017, Spire redeemed in full at par its $250.0 floating rate notes due August 15, 2017, plus accrued and unpaid interest. On March 15, 2017, Spire completed the issuance and sale of $100.0 in aggregate principal amount of Senior Notes due March 15, 2027. The notes bear interest at the rate of 3.93% per annum, payable semi-annually. The notes are senior unsecured obligations of the Company. The Company used the proceeds from the sale of the notes for the repayment of other debt. In 2014, Spire issued 2.875 million equity units as a portion of the Spire Alabama acquisition financing. The equity units were originally issued at $50 per unit pursuant to the Purchase Contract dated as of June 11, 2014 between Spire and U.S. Bank National Association, as purchase contract agent, collateral agent, custodial agent and securities intermediary. These units consisted of $143.8 aggregate principal amount of 2014 Series A 2.00% remarketable junior subordinated notes due 2022 (the Junior Notes) and the Purchase Contract obligating the holder to purchase common shares at a future settlement date. The equity unit investments were effectively replaced as planned in a series of transactions outlined below: • On February 22, 2017, the selling securityholders (as defined below) agreed to purchase the Junior Notes in connection with the remarketing of the junior subordinated notes that comprised a component of the equity units. • On the same day, Spire entered two related agreements: (1) a Securities Purchase and Registration Rights Agreement (the SPRRA), among Spire and the several purchasers named therein (the selling securityholders), obligating the selling securityholders to sell the Junior Notes to Spire in exchange for $143.8 aggregate principal amount of Spire’s 3.543% Senior Notes due 2024 (the Senior Notes) and a cash payment, and (2) an underwriting agreement with the selling securityholders and the several underwriters named therein in connection with the public offering of $150.0 aggregate principal amount of Senior Notes consisting of $6.2 principal amount of the Senior Notes issued and sold by Spire and $143.8 principal amount of the Senior Notes sold by the selling securityholders. The SPRRA granted the selling securityholders the right to offer the Senior Notes to the public in secondary public offerings. • The public offering was completed on February 27, 2017. Spire used its net proceeds from its sale of the Senior Notes to repay short-term debt. Spire did not receive any proceeds from the sale of the Senior Notes by the selling securityholders. • On April 3, 2017, Spire settled the Purchase Contracts underlying its 2.875 million equity units by issuing 2,504,684 shares of its common stock at a purchase price of $57.3921 per share. Fractional shares were settled in cash at $67.50 per share. The purchase price was funded with the proceeds from the Junior Notes. Under the contract terms, the equity units were converted to common stock at the rate of 0.8712 , with a corresponding adjustment to purchase price. Spire received net cash proceeds of approximately $142.0 , which it used to repay short-term debt incurred the previous month to redeem the floating rate notes. At September 30, 2017 , including the current portion but excluding unamortized discounts and debt issuance costs, Spire had long-term debt totaling $2,112.0 , of which $980.0 was issued by Spire Missouri, $250.0 was issued by Spire Alabama, and $67.0 was issued by other subsidiaries. All long-term debt bears fixed rates and is subject to changes in fair value as market interest rates change. However, increases and decreases in fair value would impact earnings and cash flows only if the Company were to reacquire any of these issues in the open market prior to maturity. Under GAAP applicable to the Utilities’ regulated operations, losses or gains on early redemption of long-term debt would typically be deferred as regulatory assets or regulatory liabilities and amortized over a future period. Of the Company’s $2,112.0 long-term debt (including the current portion), $25.0 has no call options, $1,037.0 has make-whole call options, $5.0 is callable currently, and $1,045.0 is callable at par one to six months prior to maturity. As indicated in Note 5 , Shareholders’ Equity, Spire has a shelf registration statement on Form S-3 on file with the SEC for the issuance of equity and debt securities. Including the current portion of long-term debt, the Company’s capitalization at September 30, 2017 consisted of 48.7% of common stock equity and 51.3% long-term debt, compared to 46.1% of common stock equity and 53.9% of long-term debt at September 30, 2016 . Spire Missouri On September 15, 2017, Spire Missouri issued and sold in a private placement $50.0 in aggregate principal amount of its first mortgage bonds due September 15, 2032, $70.0 in aggregate principal amount of its first mortgage bonds due September 15, 2047 and $50.0 in aggregate principal amount of its first mortgage bonds due September 15, 2057. Spire Missouri used the proceeds to refinance existing indebtedness and for other general corporate purposes. The 2032 bonds, 2047 bonds and 2057 bonds bear interest at a rate per annum of 3.68% , 4.23% and 4.38% , respectively, payable semi-annually on the 15th day of March and September of each year. Spire Missouri has authority from the MoPSC to issue debt securities and preferred stock, including on a private placement basis, as well as to issue common stock, receive paid-in-capital, and enter into capital lease agreements, all for a total of up to $300.0 for financings placed any time before September 30, 2018. During the year ended September 30, 2017 , Spire Missouri issued $170.0 in securities under this authorization, so as of that date, $130.0 remains available to be issued. At September 30, 2017 , including the current portion but excluding unamortized discounts and debt issuance costs, Spire Missouri had long-term debt totaling $980.0 . While these long-term debt issues are fixed-rate, they are subject to changes in fair value as market interest rates change. Of Spire Missouri’s $980.0 in long-term debt, $25.0 has no call options, $435.0 has make-whole call options and $520.0 is callable at par three to six months prior to maturity. As indicated in Note 5 , Shareholders’ Equity, Spire Missouri has a shelf registration on Form S-3 on file with the SEC for issuance of first mortgage bonds, unsecured debt, and preferred stock, which expires on September 22, 2019. Substantially all of Spire Missouri’s plant is subject to the liens of its first mortgage bonds. The mortgage contains several restrictions on Spire Missouri’s ability to pay cash dividends on its common stock, which are described in Note 5 , Shareholders’ Equity. Including the current portion of long-term debt, Spire Missouri’s capitalization at September 30, 2017 consisted of 54.6% of common stock equity and 45.4% long-term debt compared to 57.1% of common stock equity and 42.9% of long-term debt at September 30, 2016 . Spire Alabama At September 30, 2017 , excluding unamortized debt issuance costs, Spire Alabama had fixed-rate long-term debt totaling $250.0 . While these long-term debt issues are fixed-rate, they are subject to changes in fair value as market interest rates change. All of Spire Alabama’s $250.0 long-term debt has make-whole call options. Spire Alabama’s capitalization at September 30, 2017 consisted of 77.8% of common stock equity and 22.2% long-term debt, consistent with 77.8% of common stock equity and 22.2% of long-term debt at September 30, 2016 . Because Spire Alabama has no standing authority to issue long-term debt, it must petition the APSC for each planned issuance. On October 3, 2017, Spire Alabama received authorization and approval from the APSC to borrow up to $75.0 for general corporate purposes and to retire short-term debt. |

Short-term Debt [Abstract] | |
NOTES PAYABLE AND CREDIT AGREEMENTS | NOTES PAYABLE AND CREDIT AGREEMENTS Short-term cash requirements outside of the Utilities have generally been funded by Spire or met with internally generated funds . The Utilities’ short term borrowing requirements typically peak during the colder months. Total short-term borrowing requirements can be met through the sale of commercial paper supported by a revolving credit facility or through direct use of the revolving credit facility. On December 14, 2016, Spire, Spire Missouri, and Spire Alabama entered into a new syndicated revolving credit facility pursuant to a loan agreement with 11 banks, expiring December 14, 2021. The largest portion provided by a single bank under the line is 12.3% . The loan agreement replaced Spire’s and Spire Missouri’s existing loan agreements dated as of September 3, 2013 and amended September 3, 2014, which were set to expire on September 3, 2019, and Spire Alabama’s existing loan agreement dated September 2, 2014, which was set to expire September 2, 2019. All three previous agreements were terminated on December 14, 2016. 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. Spire may use its line to provide for the funding needs of various subsidiaries. Spire, Spire Missouri, and Spire Alabama expect to use the loan agreement for general corporate purposes, including short-term borrowings and letters of credit. 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 September 30, 2017, total debt was 56% of total capitalization for the consolidated Company, 50% for Spire Missouri, and 33% for Spire Alabama. There were no borrowings against this credit facility as of September 30, 2017 . On December 21, 2016, Spire established a commercial paper program (Program) pursuant to which Spire may issue short-term, unsecured commercial paper notes (Notes). Amounts available under the 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 Program at any time not to exceed $975.0 . The Notes may have maturities of up to 365 days from date of issue. The net proceeds of the issuances of the Notes are expected to be used for general corporate purposes, including to provide working capital for both utility and non-utility subsidiaries. As of September 30, 2017, Notes outstanding under the Program totaled $477.3 . Information about Spire’s consolidated short-term borrowings is presented below. Based on average short-term borrowings for the year ended September 30, 2017 , an increase in the average interest rate of 100 basis points would decrease Spire’s pre-tax earnings and cash flows by approximately $4.9 on an annual basis, portions of which may be offset through the application of PGA or GSA carrying costs.

Fair Value Disclosures [Abstract] | |
FAIR VALUE MEASUREMENTS | FAIR VALUE MEASUREMENTS Spire 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. The mutual funds included in Level 2 are valued based on the closing net asset value per unit. Derivative instruments included in Level 1 are valued using quoted market prices on the NYMEX. Derivative instruments classified as Level 2 include physical commodity derivatives that are valued using Over-the-Counter Bulletin Board (OTCBB), 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. There were no material Level 3 balances as of September 30, 2017 or 2016 . 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 “Property and other investments” on Spire Missouri’s balance sheets. Derivative assets and liabilities, including receivables and payables associated with cash margin requirements, are presented net on the balance sheets when a legally enforceable netting agreement exist between the Company or Spire Missouri and the counterparty to the derivative contract.

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES | DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Spire Spire Missouri has a risk management policy to utilize various derivatives, including futures contracts, exchange-traded options, and swaps for the explicit purpose of managing price risk associated with purchasing and delivering natural gas on a regular basis to customers in accordance with its tariffs. The objective of this policy is to limit Spire Missouri’s exposure to natural gas price volatility and to manage, hedge and mitigate substantial price risk. Further discussion of this policy can be found in the Spire Missouri section. From time to time Spire Missouri and Spire Alabama purchase NYMEX futures and options contracts to help stabilize operating costs associated with forecasted purchases of gasoline and diesel fuels used to power vehicles and equipment used in the course of their business. Further information on these derivatives can be found in the Spire Missouri and Spire Alabama sections, respectively. In the course of its business, Spire’s gas marketing subsidiary, Spire Marketing, which includes its wholly owned subsidiary Spire Storage Inc., enters into commitments associated with the purchase or sale of natural gas. Certain of Spire Marketing’s derivative natural gas contracts are designated as normal purchases or normal sales and, as such, are excluded from the scope of ASC Topic 815 and are accounted for as executory contracts on an accrual basis. Any of Spire Marketing’s derivative natural gas contracts that are not designated as normal purchases or normal sales are accounted for at fair value. At September 30, 2017 , the fair values of 202.1 million MMBtu of non-exchange traded natural gas commodity contracts were reflected in the Consolidated Balance Sheet. Of these contracts, 156.8 million MMBtu will settle during fiscal 2018 , and 34.3 million MMBtu, 5.9 million MMBtu, 4.1 million MMBtu, 0.9 million MMBtu, and 0.1 million MMBtu will settle during fiscal years 2019 , 2020 , 2021 , 2022, and 2023, respectively. These contracts have not been designated as hedges; therefore, changes in the fair value of these contracts are reported in earnings each period. Furthermore, Spire Marketing manages the price risk associated with its fixed-priced commitments by either closely matching the offsetting physical purchase or sale of natural gas at fixed prices or through the use of NYMEX or ICE futures, swap, and option contracts to lock in margins. At September 30, 2017 , Spire Marketing’s unmatched fixed-price positions were not material to Spire’s financial position or results of operations. Spire Marketing’s NYMEX and ICE natural gas futures, swap, and option contracts used to lock in margins may be designated as cash flow hedges of forecasted transactions for financial reporting purposes. During fiscal 2015, Spire Alabama entered into interest rate swap transactions to protect itself against adverse movement in interest rates in anticipation of its issuance of $115.0 of long-term debt. The notional amount of these interest rate swaps was $104.5 . These derivative instruments were designated as cash flow hedges of forecasted transactions. These forward starting swaps involved the payment of a fixed interest rate and the receipt of the London Interbank Offered Rate (LIBOR) over the terms specified in the contracts. Termination of these interest rate swap agreements later in fiscal 2015 resulted in a $2.7 gain which was recorded as a regulatory liability. Of the total issuance of long-term debt, $35.0 was issued on September 15, 2015 and $80.0 was issued on December 1, 2015, and the gain is being amortized to reduce interest expense over the hedged periods. During fiscal 2016, Spire entered into interest rate swap agreements, with a notional amount of $85.0 , to effectively lock in interest rates on a portion of the long-term debt it anticipated issuing to finance its acquisition of Spire EnergySouth. These derivative instruments were designated as cash flow hedges of forecasted transactions. Termination of the interest rate swap agreements later in fiscal 2016 resulted in a $0.4 loss recorded in accumulated other comprehensive loss to be amortized to interest expense over the life of the related debt issuances. Also during fiscal 2016, Spire entered into interest rate swap transactions with a notional amount of $225.0 to protect itself against adverse movement in interest rates in anticipation of the issuance of long-term debt in fiscal 2017. These hedge positions were settled during fiscal 2017, resulting in a gain of $14.1 which will be amortized to reduce interest expense over the hedged periods. Also during fiscal 2017, Spire entered into a ten-year interest rate swap with a fixed interest rate of 2.658 % and a notional amount of $60.0 to protect itself against adverse movements in interest rates on future interest rate payments. The Company recorded a $0.9 mark-to-market loss on these swaps as part of other comprehensive income for the year ended September 30, 2017. The Company’s and Spire Missouri’s exchange-traded/cleared derivative instruments consist primarily of NYMEX and ICE positions. The NYMEX is the primary national commodities exchange on which natural gas derivatives are traded. Open NYMEX/ICE natural gas futures and swap positions at September 30, 2017 were as follows: Gas Utility Gas Marketing MMBtu (millions) Avg. Price Per MMBtu MMBtu (millions) Avg.

Derivative instruments designated as cash flow hedges of forecasted transactions are recognized on the balance sheets of the Company at fair value, and the change in fair value of the effective portion of these hedge instruments is recorded, net of income tax, in other comprehensive income or loss (OCI). Accumulated other comprehensive income or loss (AOCI) is a component of Total Common Stock Equity. Amounts are reclassified from AOCI into earnings when the hedged items affect net income, using the same revenue or expense category that the hedged item impacts. Based on market prices at September 30, 2017 , it is expected that an immaterial amount of unrealized gains will be reclassified into the Consolidated Statements of Income of the Company during the next twelve months. Cash flows from hedging transactions are classified in the same category as the cash flows from the items that are being hedged in the Consolidated Statements of Cash Flows.

Spire Missouri Spire Missouri has a risk management policy to utilize various derivatives, including futures contracts, exchange-traded options, swaps and over-the-counter instruments for the explicit purpose of managing price risk associated with purchasing and delivering natural gas on a regular basis to customers in accordance with its tariffs. The objective of this policy is to limit Spire Missouri’s exposure to natural gas price volatility and to manage, hedge and mitigate substantial price risk. This policy strictly prohibits speculation and permits Spire Missouri to hedge current physical natural gas purchase commitments or forecasted or anticipated future peak (maximum) physical need for natural gas delivered. Costs and cost reductions, including carrying costs, associated with Spire Missouri’s use of natural gas derivative instruments are allowed to be passed on to Spire Missouri customers through the operation of its PGA clause, through which the MoPSC allows Spire Missouri to recover gas supply costs, subject to prudence review by the MoPSC. Accordingly, Spire Missouri does not expect any adverse earnings impact as a result of the use of these derivative instruments. Spire Missouri does not designate these instruments as hedging instruments for financial reporting purposes because gains or losses associated with the use of these derivative instruments are deferred and recorded as regulatory assets or regulatory liabilities pursuant to ASC Topic 980, “Regulated Operations,” and, as a result, have no direct impact on the statements of income. The timing of the operation of the PGA clause may cause interim variations in short-term cash flows, because Spire Missouri is subject to cash margin requirements associated with changes in the values of these instruments. Nevertheless, carrying costs associated with such requirements are recovered through the PGA clause. From time to time, Spire Missouri purchases NYMEX futures and options contracts to help stabilize operating costs associated with forecasted purchases of gasoline and diesel fuels used to power vehicles and equipment used in the course of its business. At September 30, 2017 , Spire Missouri held 0.3 million gallons of gasoline futures contracts at an average price of $1.27 per gallon. Most of these contracts, the longest of which extends to December 2017, are designated as cash flow hedges of forecasted transactions pursuant to ASC Topic 815, “Derivatives and Hedging.” The gains or losses on these derivative instruments are not subject to Spire Missouri’s PGA clause. Derivative instruments designated as cash flow hedges of forecasted transactions are recognized on the balance sheets at fair value and the change in the fair value of the effective portion of these hedge instruments is recorded, net of income tax, in OCI. AOCI is a component of Total Common Stock Equity. Amounts are reclassified from AOCI into earnings when the hedged items affect net income, using the same revenue or expense category that the hedged item impacts. Based on market prices at September 30, 2017 , it is expected that an immaterial amount of pre-tax gains will be reclassified into the statements of income during fiscal 2018 . Cash flows from hedging transactions are classified in the same category as the cash flows from the items that are being hedged in the statements of cash flows. Spire Missouri’s derivative instruments consist primarily of NYMEX positions. The NYMEX is the primary national commodities exchange on which natural gas derivatives are traded. Open NYMEX natural gas futures positions at September 30, 2017 were as follows: MMBtu (millions) Avg.

Spire Alabama In prior years, Spire Alabama entered into cash flow derivative commodity instruments to hedge its exposure to price fluctuations on its gas supply. Spire Alabama recognizes all derivatives at fair value as either assets or liabilities on the balance sheet. Any realized gains or losses are passed through to customers using the mechanisms of the GSA rider in accordance with Spire Alabama’s APSC approved tariff. During the second quarter of fiscal 2015, Spire Alabama entered into certain interest rate swap transactions to protect itself against adverse movement in interest rates in anticipation of its issuance of $115.0 of long-term debt. Spire Alabama received prior approval from the APSC to enter into these hedges. The notional amount of interest rate swaps outstanding was $80.5 with stated maturities ranging from 2025 to 2045 and fixed interest rates ranging between 2.18% and 2.85% . In April 2015, Spire Alabama entered into an additional hedge with a notional amount of $24.0 and terms within the same range. These derivative instruments were designated as cash flow hedges of forecasted transactions. These forward starting swaps involved the payment of a fixed interest rate and the receipt of LIBOR over the terms specified in the contracts. On May 21, 2015, the interest rate swap agreements were terminated and the settlement resulted in a $2.7 gain which was recorded as a regulatory liability. Of the total issuance of long-term debt, $35.0 was issued on September 15, 2015 and the remaining $80.0 was issued on December 1, 2015. During the fiscal second quarter of 2016, Spire Alabama commenced a gasoline derivative program to help stabilize operating costs associated with forecasted purchases of gasoline and diesel fuels used to power vehicles and equipment used in the course of its business. At September 30, 2017 , Spire Alabama held 0.1 million gallons of gasoline futures contracts at an average price of $1.28 per gallon. Most of these contracts, the longest of which extends to December 2017, are designated as cash flow hedges of forecasted transactions pursuant to ASC Topic 815, “Derivatives and Hedging.” The gains or losses on these derivative instruments are not subject to Spire Alabama’s GSA rider. As of September 30, 2017 and 2016, the fair value of gasoline contracts was not significant. |

Risks and Uncertainties [Abstract] | |
CONCENTRATIONS OF CREDIT RISK | CONCENTRATIONS OF CREDIT RISK Other than in Spire Marketing, Spire has no significant concentration of credit risk. 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 guarantees. 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 accounts receivable attributable to energy producers and their marketing affiliates amounted to $17.9 at September 30, 2017 ( $8.9 reflecting netting arrangements). Spire Marketing’s accounts receivable attributable to utility companies and their marketing affiliates comprised $58.2 of total accounts receivable at September 30, 2017 ( $55.8 reflecting netting arrangements). Spire Marketing also has concentrations of credit risk with certain individually significant counterparties and with pipeline companies associated with its natural gas receivable amount. At September 30, 2017 , the amounts included in accounts receivable from Spire Marketing’s five largest counterparties (in terms of net accounts receivable exposure) totaled $23.8 ( $23.1 reflecting netting arrangements). Four of these five counterparties are investment-grade rated companies. The fifth is not rated, but each of its owners is investment-grade. |

INCOME TAXES | INCOME TAXES Spire The Company’s provision for income taxes charged during the fiscal years ended September 30, 2017 , 2016 , and 2015 are as follows: 2017 2016 2015 Federal Current $ 0.1 $ 0.1 $ (3.3 ) Deferred 67.7 62.0 58.8 Investment tax credits (0.2 ) (0.2 ) (0.2 ) State and local Current 0.5 0.6 — Deferred 9.5 7.0 6.9 Total income tax expense $ 77.6 $ 69.5 $ 62.2 The Company’s effective income tax rate varied from the federal statutory income tax rate for each year due to the following: 2017 2016 2015 Federal income tax statutory rate 35.0 % 35.0 % 35.0 % State and local income taxes, net of federal income tax benefits 2.8 2.8 3.0 Certain expenses capitalized on books and deducted on tax return (2.3 ) (3.4 ) (3.7 ) Taxes related to prior years (0.9 ) (0.2 ) (0.6 ) Other items – net * (2.2 ) (1.7 ) (2.5 ) Effective income tax rate 32.4 % 32.5 % 31.2 % * Other consists primarily of property adjustments. The Company’s significant items comprising the net deferred tax liability recorded in the Consolidated Balance Sheets as of September 30 are as follows: 2017 2016 Deferred tax assets: Reserves not currently deductible $ 31.5 $ 21.3 Pension and other postretirement benefits 58.6 68.3 Operating losses 169.6 102.3 Other 26.0 — Deferred tax assets 285.7 191.9 Less: valuation allowance 0.5 0.9 Total deferred tax assets 285.2 191.0 Deferred tax liabilities: Relating to property 728.3 623.1 Regulatory pension and other postretirement benefits 108.0 106.8 Deferred gas costs 30.6 20.0 Other** 125.8 48.4 Total deferred tax liabilities 992.7 798.3 Net deferred tax liability $ 707.5 $ 607.3 ** Other consists primarily of Goodwill related liabilities. In assessing whether deferred tax assets are realizable, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. Management considers all significant available positive and negative evidence, including the existence of losses in recent years, the timing of deferred tax liability reversals, projected future taxable income, taxable income in carryback years, and tax planning strategies to assess the need for a valuation allowance. Based upon this evidence, management believes it is more likely than not the Company will realize the benefits of these deferred tax assets, except for the contribution carryforward valuation allowance noted below. The Company has federal and state loss carryforwards of approximately $478.6 at September 30, 2017 . The Company also has contribution carryforwards of approximately $12.1 at September 30, 2017 . The loss carryforwards begin to expire in fiscal 2030 for certain state purposes and fiscal 2035 for federal and other states purposes. The contribution carryforwards begin to expire in fiscal 2018. The Company has a valuation allowance of $0.5 as a portion of the contribution carryforward will not be realized prior to its expiration. The Company also has various tax credit carryforwards of approximately $2.5 that begin to expire in 2020. The Company recognizes the tax benefit from a tax position only if it is at least more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The Company records potential interest and penalties related to its uncertain tax positions as interest expense and other income deductions, respectively. Unrecognized tax benefits are reported as a reduction of a deferred tax asset for an operating loss carryforward. The following table presents a reconciliation of the beginning and ending balances of the Company’s unrecognized tax benefits: 2017 2016 2015 Unrecognized tax benefits, beginning of year $ 10.0 $ 7.1 $ 4.6 Increases related to tax positions taken in current year 2.4 3.4 2.9 Reductions due to lapse of applicable statute of limitations (1.4 ) (0.5 ) (0.4 ) Unrecognized tax benefits, end of year $ 11.0 $ 10.0 $ 7.1 The amount of unrecognized tax benefits which, if recognized, would affect the Company’s effective tax rate were $5.1 and $3.3 as of September 30, 2017 and 2016 , respectively. It is reasonably possible that events will occur in the next 12 months that could increase or decrease the amount of the Company’s unrecognized tax benefits. The Company does not expect that any such change will be significant to the Consolidated Balance Sheets. As of September 30, 2017 and 2016 , interest accrued associated with the Company’s uncertain tax positions was de minimis, and no penalties were accrued as of September 30, 2017 . The Company is subject to US federal income tax as well as income tax in various state and local jurisdictions. The Company is no longer subject to examination for fiscal years prior to 2014. Regarding the Company’s recent Spire EnergySouth acquisition, tax returns for calendar years 2013 through 2015 remain open and subject to examination by the Internal Revenue Service and state taxing jurisdictions. These returns cover periods during which Spire EnergySouth was owned by Sempra Global. The impact of any adjustments made to these returns by the relevant taxing authorities would be addressed by the indemnification provisions of the stock purchase agreement with Sempra Global.

Spire Missouri has federal and state loss carryforwards of approximately $166.0 , at September 30, 2017 , based on a separate company basis. For federal tax purposes, these loss carryforwards may be utilized against income from another member of the consolidated group. Spire Missouri also has contribution carryforwards of approximately $11.2 at September 30, 2017 . The loss carryforwards begin to expire in fiscal 2035 for federal and state purposes. The contribution carryforwards begin to expire in fiscal 2018.

Defined Contribution Plan [Abstract] | |
PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS | PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS The Spire information in this note reflects all plans of the Company, including information for plans of Spire EnergySouth since September 12, 2016. The net pension and postretirement obligations were re-measured at that acquisition date as well as at the fiscal year end. Pension Plans The pension plans of Spire consist of plans for employees at the Missouri Utilities, plans covering the employees of Spire Alabama, and plans covering employees of the subsidiaries of Spire EnergySouth. 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 US 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 US equities with varying strategies, global equities, alternative investments, and fixed income investments. The net periodic pension costs include the following components: Spire Spire Missouri Spire Alabama 2017 2016 2015 2017 2016 2015 2017 2016 2015 Service cost – benefits earned during the period $ 20.5 $ 15.3 $ 17.3 $ 12.7 $ 10.0 $ 11.5 $ 6.2 $ 5.3 $ 5.8 Interest cost on projected benefit obligation 27.9 28.0 29.5 19.5 21.7 23.3 6.1 6.3 6.2 Expected return on plan assets (38.5 ) (34.9 ) (37.4 ) (28.1 ) (26.7 ) (29.2 ) (7.2 ) (8.2 ) (8.2 ) Amortization of prior service cost 1.0 0.4 0.5 1.0 0.4 0.5 — — — Amortization of actuarial loss 12.5 8.0 7.5 10.7 7.9 7.5 1.8 0.1 — Loss on lump-sum settlements and curtailments 17.9 3.3 19.6 13.5 — 18.0 4.6 3.3 1.6 Special termination benefits 0.9 1.6 — — 1.6 — — — — Subtotal 42.2 21.7 37.0 29.3 14.9 31.6 11.5 6.8 5.4 Regulatory adjustment (2.4 ) 17.8 (2.1 ) (4.1 ) 11.7 (5.2 ) 1.8 6.1 3.1 Net pension cost $ 39.8 $ 39.5 $ 34.9 $ 25.2 $ 26.6 $ 26.4 $ 13.3 $ 12.9 $ 8.5 Other changes in plan assets and pension benefit obligations recognized in other comprehensive income or loss include the following: Spire Spire Missouri Spire Alabama 2017 2016 2015 2017 2016 2015 2017 2016 2015 Current year actuarial loss $ 14.1 $ 46.8 $ 48.3 $ 14.8 $ 21.6 $ 26.0 $ 3.3 $ 25.2 $ 22.3 Amortization of actuarial loss (12.5 ) (8.0 ) (7.5 ) (10.7 ) (7.9 ) (7.5 ) (1.8 ) (0.1 ) — Acceleration of loss recognized due to settlement (18.2 ) (3.3 ) (19.6 ) (13.5 ) — (18.0 ) (4.5 ) (3.3 ) (1.6 ) Current year service cost — 5.0 — — 5.0 — — — — Current year prior year service cost (20.7 ) — — — — — (20.7 ) — — Amortization of prior service cost (1.0 ) (0.4 ) (0.5 ) (1.0 ) (0.4 ) (0.5 ) — — — Subtotal (38.3 ) 40.1 20.7 (10.4 ) 18.3 — (23.7 ) 21.8 20.7 Regulatory adjustment 38.0 (39.8 ) (21.2 ) 10.1 (18.0 ) (0.5 ) 23.7 (21.8 ) (20.7 ) Total recognized in OCI $ (0.3 ) $ 0.3 $ (0.5 ) $ (0.3 ) $ 0.3 $ (0.5 ) $ — $ — $ — Spire pension obligations are driven by separate plan and regulatory provisions governing Spire Missouri, Spire Alabama and Spire EnergySouth pension plans. 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 100% of 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. Two Spire Alabama plans and one Spire Missouri plan met the criteria for settlement recognition in the fiscal year ended September 30, 2017 , requiring re-measurement of the obligation under those plans using updated census data and assumptions for discount rate and mortality. Lump-sum payments recognized as settlements during fiscal years 2017 , 2016 , and 2015 were $62.2 ( $43.5 attributable to Spire Missouri and $18.7 to Spire Alabama), $16.6 (attributable to Spire Alabama), and $71.1 ( $58.2 attributable to Spire Missouri and $12.9 to Spire Alabama), respectively. Pursuant to a MoPSC Order, the return on plan assets is based on the market-related value of plan assets implemented prospectively over a four -year period. Gains or losses not yet includible in pension cost are amortized only to the extent that such gain or loss exceeds 10% of the greater of the projected benefit obligation or the market-related value of plan assets. Such excess is amortized over the average remaining service life of active participants. The recovery in rates for Spire Missouri East’s qualified pension plan is based on an annual allowance of $15.5 effective January 1, 2011. The recovery in rates for Spire Missouri West’s qualified pension plan is based on an annual allowance of approximately $10 effective February 20, 2010. The difference between these amounts and pension expense as calculated pursuant to the above and that otherwise would be included in the statements of income and statements of comprehensive income is deferred as a regulatory asset or regulatory liability.

The expected long-term rate of return on plan assets is based on historical and projected rates of return for current and planned asset classes in the investment portfolio. Assumed projected rates of return for each asset class were selected after analyzing historical experience and future expectations of the returns. The overall expected rate of return for the portfolio was developed based on the target allocation for each class.

Spire Missouri’s investment policies are designed to maximize, to the extent possible, the funded status of the plans over time, and minimize volatility of funding and costs. The policy seeks to maximize investment returns consistent with these objectives and Spire Missouri’s tolerance for risk. The duration of plan liabilities and the impact of potential changes in asset values on the funded status are fundamental considerations in the selection of plan assets. Outside investment management specialists are utilized in each asset class. Such specialists are provided with guidelines, where appropriate, designed to ensure that the investment portfolio is managed in accordance with the policy. The policy seeks to avoid significant concentrations of risk by investing in a diversified portfolio of assets, currently including a growth (equity) component and a liability-driven (debt) component. Investments in corporate, US government and agencies, and, to a lesser extent, international debt securities seek to provide duration matching with plan liabilities, and typically have investment grade ratings and reflect allocations across various entities and industries. There are also exposures to additional asset types in the target portfolio: commodities, real estate and inflation-indexed securities. For the Missouri East plan, the investment policy permits the use of derivative instruments, which may be used to achieve the desired market exposure of an index, adjust portfolio duration, or rebalance the total portfolio to the target asset allocation. The growth strategy utilizes a combination of derivative instruments and debt securities to achieve diversified exposure to equity and other markets while generating returns from the fixed-income investments and providing further duration matching with the liabilities. Performance and compliance with the guidelines is regularly monitored. The policy calls for increased allocations to debt securities as the funded status improves. Spire Alabama employs a total return investment approach whereby a mix of equities and fixed income investments are used to maximize the long-term return of plan assets with a prudent level of risk. Risk tolerance is established through consideration of plan liabilities, plan funded status, corporate financial condition and market conditions. Spire Alabama has developed an investment strategy that focuses on asset allocation, diversification and quality guidelines. The investment goals are to obtain an adequate level of return to meet future obligations of the plans by providing above average risk-adjusted returns with a risk exposure in the mid-range of comparable funds. Investment managers are retained by Spire Alabama to manage separate pools of assets. Funds are allocated to such managers in order to achieve an appropriate, diversified, and balanced asset mix. Comparative market and peer group benchmarks are utilized to ensure that investment managers are performing satisfactorily. Spire Alabama seeks to maintain an appropriate level of diversification to minimize the risk of large losses in a single asset class. Accordingly, plan assets for the pension plans do not have a concentration of assets in a single entity, industry, country, commodity or class of investment fund. Following are expected pension benefit payments for the succeeding five fiscal years, and in aggregate for the five fiscal years thereafter, for Spire, Spire Missouri, and Spire Alabama: 2018 2019 2020 2021 2022 2023- 2027 Spire $ 63.5 $ 63.2 $ 63.2 $ 58.1 $ 57.9 $ 281.1 Spire Missouri 50.7 49.5 49.1 43.5 42.1 198.1 Spire Alabama 10.3 11.1 11.5 11.9 13.0 67.8 The funding policy of Spire Missouri and Spire Alabama 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. Spire Missouri contributions to the pension plans in fiscal 2018 are anticipated to be $35.5 into the qualified trusts, and $0.5 into the non-qualified plans. Spire Alabama had no required contributions to the qualified pension plans during 2017. Additionally, it is not anticipated that the funded status of the qualified pension plans will fall below statutory thresholds requiring accelerated funding or constraints on benefit levels or plan administration. During fiscal 2017, Spire Alabama made discretionary contributions to the qualified pension plans totaling $11.9; none are expected in fiscal 2018. Postretirement Benefits 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. For retirements after January 1, 2015, the Spire Missouri West plans provide medical insurance after early retirement until age 65 . Under the Spire Alabama plans, medical insurance is currently available 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 consist of the following components: Spire Spire Missouri Spire Alabama 2017 2016 2015 2017 2016 2015 2017 2016 2015 Service cost – benefits earned during the period $ 11.0 $ 10.9 $ 12.8 $ 10.4 $ 10.6 $ 12.3 $ 0.3 $ 0.3 $ 0.5 Interest cost on accumulated postretirement benefit obligation 8.6 10.2 11.2 6.8 8.1 8.6 1.6 2.1 2.6 Expected return on plan assets (13.6 ) (13.5 ) (13.2 ) (9.0 ) (8.5 ) (8.1 ) (4.4 ) (5.0 ) (5.1 ) Amortization of prior service cost (credit) — 0.3 0.8 0.2 0.3 0.8 (0.2 ) — — Amortization of actuarial loss (gain) 2.5 3.6 5.1 2.6 3.8 5.1 (0.1 ) (0.2 ) — Special termination benefits — 2.6 — — 2.6 — — — — Subtotal 8.5 14.1 16.7 11.0 16.9 18.7 (2.8 ) (2.8 ) (2.0 ) Regulatory adjustment (3.2 ) (6.6 ) (11.0 ) (1.5 ) (4.8 ) (9.2 ) (1.8 ) (1.8 ) (1.8 ) Net postretirement benefit cost $ 5.3 $ 7.5 $ 5.7 $ 9.5 $ 12.1 $ 9.5 $ (4.6 ) $ (4.6 ) $ (3.8 ) Other changes in plan assets and postretirement benefit obligations recognized in OCI include the following: Spire Spire Missouri Spire Alabama 2017 2016 2015 2017 2016 2015 2017 2016 2015 Current year actuarial (gain) loss $ (34.1 ) $ 0.8 $ (8.5 ) $ (28.5 ) $ 1.4 $ (2.4 ) $ (4.5 ) $ (0.6 ) $ (6.1 ) Amortization of actuarial (loss) gain (2.5 ) (3.6 ) (5.1 ) (2.6 ) (3.8 ) (5.1 ) 0.1 0.2 — Current year prior service credit (1.4 ) (1.8 ) (4.9 ) — — (4.9 ) (1.4 ) (1.8 ) — Amortization of prior service (cost) credit — (0.3 ) (0.8 ) (0.2 ) (0.3 ) (0.8 ) 0.2 — — Subtotal (38.0 ) (4.9 ) (19.3 ) (31.3 ) (2.7 ) (13.2 ) (5.6 ) (2.2 ) (6.1 ) Regulatory adjustment 38.0 4.9 19.3 31.3 2.7 13.2 5.6 2.2 6.1 Total recognized in OCI $ — $ — $ — $ — $ — $ — $ — $ — $ — Pursuant to a MoPSC Order, the return on plan assets is based on the market-related value of plan assets implemented prospectively over a four -year period. Gains and losses not yet includible in postretirement benefit cost are amortized only to the extent that such gain or loss exceeds 10% of the greater of the accumulated postretirement benefit obligation or the market-related value of plan assets. Such excess is amortized over the average remaining service life of active participants. The recovery in rates for Spire Missouri’s postretirement benefit plans is based on an annual allowance of $9.5 effective January 1, 2011. The difference between these amounts and postretirement benefit cost based on the above and that otherwise would be included in the statements of income and statements of comprehensive income is deferred as a regulatory asset or regulatory liability.

Segment Reporting [Abstract] | |
INFORMATION BY OPERATING SEGMENT | INFORMATION BY OPERATING SEGMENT Spire 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, and Spire Storage Inc., which utilizes natural gas storage contracts for providing natural gas sales. Other includes: • unallocated corporate items, including certain debt and associated interest costs; • Spire STL Pipeline, a subsidiary of Spire planning construction and operation of a proposed 65-mile FERC regulated pipeline to deliver natural gas into eastern Missouri; and • Spire’s subsidiaries engaged in the operation of a propane pipeline, 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, sales of natural gas from Spire Missouri to Spire Marketing, propane transportation services provided by Spire NGL Inc. (formerly Laclede Pipeline Company) 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 net unrealized gains and losses and other timing differences associated with energy-related transactions. Net economic earnings also exclude the after-tax impacts related to acquisition, divestiture, and restructuring activities.

Regulated Operations [Abstract] | |
REGULATORY MATTERS | REGULATORY MATTERS The Utilities account for regulated operations in accordance with 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. Also, 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). The following regulatory assets and regulatory liabilities were reflected in the Balance Sheets as of September 30, 2017 and 2016 . Unamortized Purchased Gas Adjustments are also included below, which are reported separately in the current assets and liabilities sections of each balance sheet. Spire Spire Missouri Spire Alabama September 30 2017 2016 2017 2016 2017 2016 Regulatory Assets: Current: Pension and postretirement benefit costs $ 42.2 $ 27.0 $ 34.9 $ 20.2 $ 7.2 $ 6.8 Unamortized purchased gas adjustments 102.6 49.7 57.4 43.1 45.2 5.6 Other 30.7 17.2 3.3 3.7 12.2 8.1 Total Current Regulatory Assets 175.5 93.9 95.6 67.0 64.6 20.5 Noncurrent: Future income taxes due from customers 170.5 151.3 170.5 151.3 — — Pension and postretirement benefit costs 404.7 487.9 322.7 375.7 72.6 98.9 Cost of removal 123.3 130.6 — — 123.3 130.6 Unamortized purchased gas adjustments 9.9 12.6 9.9 12.6 — — Energy efficiency 29.0 25.5 29.0 25.5 — — Other 53.7 30.1 25.7 24.7 1.1 1.2 Total Noncurrent Regulatory Assets 791.1 838.0 557.8 589.8 197.0 230.7 Total Regulatory Assets $ 966.6 $ 931.9 $ 653.4 $ 656.8 $ 261.6 $ 251.2 Regulatory Liabilities: Current: RSE adjustment $ 1.4 $ 7.5 $ — $ — $ 1.4 $ 5.0 Unbilled service margin — 5.9 — — — 5.9 Refundable negative salvage 8.2 9.3 — — 8.2 9.3 Unamortized purchased gas adjustments 1.0 1.7 — — — — Other 12.0 6.2 2.7 1.3 2.4 2.5 Total Current Regulatory Liabilities 22.6 30.6 2.7 1.3 12.0 22.7 Noncurrent: Pension and postretirement benefit costs 32.2 28.9 — — 32.2 28.9 Refundable negative salvage 4.1 9.4 — — 4.1 9.4 Accrued cost of removal 83.8 74.8 54.5 55.1 — — Other 37.1 17.6 26.7 12.2 3.3 3.4 Total Noncurrent Regulatory Liabilities 157.2 130.7 81.2 67.3 39.6 41.7 Total Regulatory Liabilities $ 179.8 $ 161.3 $ 83.9 $ 68.6 $ 51.6 $ 64.4 A portion of the Company’s regulatory assets are not earning a return and are shown in the schedule below: Spire Spire Missouri September 30 2017 2016 2017 2016 Future income taxes due from customers $ 170.5 $ 151.3 $ 170.5 $ 151.3 Pension and postretirement benefit costs 198.5 240.6 198.5 240.6 Other 11.3 12.9 11.3 12.9 Total Regulatory Assets Not Earning a Return $ 380.3 $ 404.8 $ 380.3 $ 404.8 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 postretirement benefit costs could be as long as 20 years, 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. Spire Missouri On September 30, 2016 Spire Missouri filed to increase its Infrastructure System Replacement Surcharge (ISRS) revenues by $5.0 for Spire Missouri East and $3.4 for Spire Missouri West, related to ISRS investments from March 2016 through October 2016. On November 29, 2016, MoPSC staff recommended $4.5 and $3.4 for Spire Missouri East and Spire Missouri West, respectively, based on updated filings. On January 3, 2017, the MoPSC held a hearing to decide two issues raised by the Missouri Office of the Public Counsel (OPC) pertaining to the ISRS eligibility of hydrostatic testing done by Spire Missouri West and of the replacement of cast iron main interspersed with portions of plastic pipe. On January 18, 2017, the MoPSC found in favor of the Missouri Utilities on the interspersed plastics issue, but against Spire Missouri West on hydrostatic testing, and issued an order setting the ISRS increases at $4.5 and $3.2 for Spire Missouri East and Spire Missouri West, respectively, bringing total annualized ISRS revenue to $29.5 and $13.4 , respectively. Rates were effective January 28, 2017. On March 3, 2017, the OPC filed an appeal to Missouri’s Western District Court of Appeals of the MoPSC’s decision permitting Spire Missouri to include in the ISRS the replacement of cast iron main interspersed with plastic pipe. The appeal will be heard in November 2017. On February 3, 2017, Spire Missouri filed to increase its ISRS revenues, by $3.3 for Spire Missouri East and $2.9 for Spire Missouri West, related to ISRS investments from November 2016 through February 2017. Following the submission of updated information, on April 4, 2017, MoPSC staff submitted its recommendation for an increase in rates of approximately $3.0 each, for a cumulative total of $32.6 and $16.4 for Spire Missouri East and Spire Missouri West, respectively. On that same date, the OPC again raised an objection to the ISRS eligibility of replacing cast iron main interspersed with portions of plastic. On April 18, 2017, the parties filed with the MoPSC a unanimous stipulation and agreement proposing to apply the judicial outcome of the OPC’s March 3, 2017 appeal on the plastics issue to both the ISRS cases on appeal and the current ISRS cases. The agreement was approved by the MoPSC on April 26, 2017. ISRS rates for each of the two service territories were increased by the MoPSC staff-recommended amounts, effective June 1, 2017. On April 15, 2015, Spire Missouri applied to the MoPSC for a new authorization of long-term financing in the amount of $550.0 . On February 10, 2016, the MoPSC issued an order, by a 3-2 vote, authorizing Spire Missouri financing authority of $300.0 for long-term financings placed any time before September 30, 2018. Spire Missouri filed an application for rehearing, which was denied on March 9, 2016. On March 31, 2016, Spire Missouri filed an appeal with Missouri’s Western District Court of Appeals concerning this matter. The parties filed briefs and oral arguments were heard on November 17, 2016. On May 30, 2017, Missouri’s Western District Court of Appeals issued a decision upholding the MoPSC’s February 10, 2016 Order granting Spire Missouri $300.0 in long-term financing authority. On July 5, 2017, the Court denied Spire Missouri’s request to transfer the case to the Missouri Supreme Court, and on October 5, 2017, the Missouri Supreme Court declined to hear Spire Missouri’s direct appeal. On March 20, 2017, Spire Missouri entered into a bond purchase agreement for $170.0 that was funded on September 15, 2017, and applied against the $300.0 authorization. On April 11, 2017, both Spire Missouri East and Spire Missouri West filed for a general rate case, and did so concurrently as agreed to in GM-2013-0254, as part of the acquisition of Spire Missouri West by Spire Missouri in fiscal 2013. The request for Spire Missouri East represents a net rate increase of $25.5 . With the $32.6 already being billed in ISRS, the total base rate increase request was $58.1 . Spire Missouri West’s request represents a net rate increase of $34.0 . With the $16.4 already being billed in ISRS, the total base rate increase request was $50.4 . The rates were premised upon a 10.35% return on equity and the details of the filing can be found in GR-2017-0215 and GR-2017-0216 for Spire Missouri East and Spire Missouri West, respectively. An evidentiary hearing has been set for December 4 through 15, 2017, with a MoPSC decision expected by February 2018. Missouri statutes require new rates to be effective within 11 months of the filing, or by March 8, 2018. Spire Alabama Spire Alabama is subject to regulation by the APSC which established the Rate Stabilization and Equalization (RSE) rate-setting process in 1983. Spire Alabama’s current RSE order has a term extending beyond September 30, 2018, unless the APSC enters an order to the contrary in a manner consistent with law. In the event of unforeseen circumstances, whether physical or economic, of the nature of force majeure and including a change in control, the APSC and Spire Alabama will consult in good faith with respect to modifications, if any. Effective January 1, 2014, Spire Alabama’s allowed range of return on average common equity is 10.5% to 10.95% with an adjusting point of 10.8% . Spire Alabama is eligible to receive a performance-based adjustment of 5 basis points to the return on equity adjusting point, based on meeting certain customer satisfaction criteria. Under RSE, the APSC conducts quarterly reviews to determine whether Spire Alabama’s return on average common equity at the end of the rate year will be within the allowed range of return. Reductions in rates can be made quarterly to bring the projected return within the allowed range; increases, however, are allowed only once each rate year, effective December 1, and cannot exceed 4% of prior-year revenues. The RSE reduction for the July 31, 2016 quarterly point of test was $4.8 and went into effect October 1, 2016, and for the quarterly point of test at September 30, 2016, Spire Alabama recorded a $2.7 RSE reduction effective December 1, 2016. As part of the annual update for RSE, on November 30, 2016, Spire Alabama filed a reduction for rate year 2017 of $2.5 that also became effective December 1, 2016. There was no RSE reduction for the January 31, 2017 , April 30, 2017 and July 31, 2017 points of test. As of September 30, 2017, Spire Alabama recorded a $2.7 RSE reduction to operating revenues to bring the expected rate of return on average common equity at the end of the year to within the allowed range of return. The inflation-based Cost Control Measure (CCM), established by the APSC, allows for annual increases to operation and maintenance (O&M) expense. The CCM range is Spire Alabama’s 2007 actual rate year O&M expense inflation-adjusted using the June Consumer Price Index For All Urban Consumers each rate year plus or minus 1.75% (Index Range). If rate year O&M expense falls within the Index Range, no adjustment is required. If rate year O&M expense exceeds the Index Range, three-quarters of the difference is returned to customers through future rate adjustments. To the extent rate year O&M is less than the Index Range, Spire Alabama benefits by one-half of the difference through future rate adjustments. Certain items that fluctuate based on situations demonstrated to be beyond Spire Alabama’s control may be excluded from the CCM calculation. As of September 30, 2017, Spire Alabama recorded a CCM benefit of $10.7 for rate year 2017, which will be reflected in rates effective December 1, 2017. The CCM benefit was $7.8 for rate year 2016 and $4.7 for rate year 2015. On June 28, 2010, the APSC approved a reduction in depreciation rates, effective June 1, 2010, and a regulatory liability recorded for Spire Alabama. Refunds from such negative salvage liability will be passed back to eligible customers on a declining basis through lower tariff rates through rate year 2019 pursuant to the terms of the Negative Salvage Rebalancing (NSR) rider. The total amount refundable to customers is subject to adjustments over the remaining period for charges made to the Enhanced Stability Reserve (ESR) and other APSC-approved charges. The refunds are due to a re-estimation of future removal costs provided for through the prior depreciation rates. For fiscal 2017, approximately $6.3 of the customer refund was returned to customers. As of September 30, 2017, $12.3 is remaining to be refunded to customers. The NSR pass back for fiscal 2018 is $8.2 and will be reflected in rates effective December 1, 2017 through March 31, 2018. Spire Alabama has APSC approval for an intercompany revolving credit agreement allowing Spire Alabama to borrow from Spire in a principal amount not to exceed $200.0 at any time outstanding in combination with its bank line of credit, and to loan to Spire in a principal amount not to exceed $25.0 at any time outstanding. Borrowings may be used for the following purposes: (a) meeting increased working capital requirements; (b) financing construction requirements related to additions, extensions, and replacements of the distribution systems; and (c) financing other expenditures that may arise from time to time in the normal course of business. On September 18, 2017, Spire Alabama filed an application with the APSC for authorization to issue and sell $75.0 principal amount of debt and to purchase interest rate derivative instruments for the purpose of locking in favorable interest rates and to include the associated interest charges, issuance costs, fees and any gain or loss resulting from the settlement of such interest rate derivative instruments through rates. The application was approved by the APSC October 3, 2017. |

Commitments and Contingencies Disclosure [Abstract] | |
COMMITMENTS AND CONTINGENCIES | COMMITMENTS AND CONTINGENCIES Commitments The Company and the Utilities have entered into contracts with various counterparties, expiring on dates through 2031, for the storage, transportation, and supply of natural gas. Minimum payments required under the contracts in place at September 30, 2017 are estimated at $1,281.8 , $563.9 and $285.6 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. Spire NGL Inc. is providing liquid propane transportation service to Spire Missouri pursuant to an approved FERC tariff and a contractual arrangement with Spire Missouri. In accordance with the terms of that agreement, Spire Missouri is obligated to pay Spire NGL Inc. approximately $1.0 annually, at current rates. The agreement renews at the end of each contract year, unless terminated by either party upon provision of at least six months’ notice. A consolidated subsidiary is a general partner in an unconsolidated partnership that invests in real estate partnerships. The subsidiary and third parties are jointly and severally liable for the payment of mortgage loans in the aggregate outstanding amount of approximately $1.3 incurred in connection with various real estate ventures. Spire has no reason to believe that the other principal liable parties will not be able to meet their proportionate share of these obligations. Spire further believes that the asset values of the real estate properties are sufficient to support these mortgage loans. Leases Aggregate rental expense and annual minimum rental commitments under all leases having an initial or remaining non-cancelable term of more than one year are shown below: Aggregate Rental Expense Minimum Rental Commitments 2017 2016 2015 2018 2019 2020 2021 2022 Later Total Spire $ 9.7 $ 11.9 $ 14.1 $ 10.1 $ 9.3 $ 7.8 $ 6.1 $ 6.0 $ 44.4 $ 83.7 Spire Missouri 4.8 4.3 7.6 2.1 1.3 0.2 0.2 — — 3.8 Spire Alabama 4.6 3.7 4.0 4.0 4.1 3.8 2.1 2.1 2.8 18.9 The lease agreement covering the Company’s primary office space in Missouri extends through January 2035. The lease agreement covering the primary office space of Spire Alabama extends through February 2020. Spire Alabama has an operating lease for additional office space that extends to January 31, 2024. Spire Alabama has subleased all of this additional office space to Energen pursuant to a sublease that expires on December 31, 2019 with an option to extend through January 31, 2024. Amounts in the table above have not been reduced for sublease rentals. For Spire Alabama and Spire, sublease rentals were $2.1 , $2.1 , and $2.1 for fiscal years 2017, 2016, and 2015, and minimum future rentals to be received in fiscal years 2018, 2019, and 2020 are $2.1 , $2.1 , and $0.5 , respectively. Spire Missouri, Spire Alabama and Spire Marketing have other relatively minor rental arrangements that provide for minimum rental payments. Contingencies The Company and Utilities account for environmental liabilities and other contingencies 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. 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 addition to matters noted below, the Company, Spire Missouri, and Spire Alabama are involved in other litigation, claims, and investigations arising in the normal course of business. Management, after discussion with counsel, believes that 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. 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. Spire On June 14, 2017, Spire filed a lawsuit against Cellular South, Inc. d/b/a C-Spire in federal district court for the Southern District of Alabama, Civil Action 17-00266-KD-N, seeking a declaratory order that Spire’s SPIRE trademarks do not infringe upon Cellular South’s C-SPIRE trademarks, and that Spire is entitled to federal registration of its trademarks. In prior proceedings before the United States Patent and Trademark Office, Cellular South filed oppositions to Spire’s attempts to register the SPIRE name, the SPIRE logo and the SPIRE LOGO + HANDSHAKE trademarks. In answer to Spire’s lawsuit, Cellular South filed counterclaims alleging infringement and unfair business practices, and seeking a declaration of infringement and that SPIRE marks are not registrable by Spire. On September 11, 2017, a federal district court judge denied Cellular South’s motion for a temporary restraining order and an injunction that would have prohibited Spire from using the SPIRE trademarks in Alabama and Mississippi. After consultation with counsel, the Company does not believe that the final resolution of this matter will have a detrimental impact on the Company’s financial condition or results of operations. Spire Gulf is in the chain of title of one former MGP site which it still owns in Mobile, Alabama. On September 15, 2010, Spire Gulf filed an application to enroll the site into the Alabama Department of Environmental Management’s (ADEM) Voluntary Cleanup Program. This application was accepted by ADEM on November 16, 2010. Investigation and testing have been completed. Spire Gulf received an approved remediation plan from ADEM and the remedial actions under the plan were completed in fiscal 2017. Spire Gulf and the Company do not expect potential liabilities that may arise from remediating this site to have a material impact on their future financial condition or results of operations. Since April 2012, a total of 14 lawsuits have been filed against Spire Gulf in Mobile County Circuit Court alleging that in the first half of 2008, Spire Gulf spilled tert-butyl mercaptan, an odorant added to natural gas for safety reasons, in Eight Mile, Alabama. Eleven of the lawsuits have been settled. The remaining three lawsuits, which include approximately 270 individual plaintiffs, allege nuisance, fraud and negligence causes of actions, and seek unspecified compensatory and punitive damages. The Company has resolved all coverage disputes with its insurance carriers relating to this matter. The Company does not expect potential liabilities that may arise from these lawsuits to have a material impact on its future financial condition or results of operations. Spire Missouri Spire Missouri has identified four former MGP sites in eastern Missouri where costs have been incurred and claims have been asserted: one in Shrewsbury, Missouri and three in the city of St. Louis, Missouri (City). Spire Missouri has enrolled two of the sites in the City in the Missouri Department of Natural Resources Brownfields/Voluntary Cleanup Program (BVCP). The third site in the City is the result of a more recent claim assertion by the United States Environmental Protection Agency (EPA), and such claim is currently being investigated. With regard to the former MGP site located in Shrewsbury, Missouri, Spire Missouri and state and federal environmental regulators agreed upon certain remedial actions to a portion of the site in a 1999 Administrative Order on Consent (AOC), which actions have been completed. On September 22, 2008, EPA Region 7 issued a letter of Termination and Satisfaction terminating the AOC. However, if after this termination of the AOC, regulators require additional remedial actions, or additional claims are asserted, Spire Missouri may incur additional costs. In conjunction with redevelopment of one of the sites located in the City, Spire Missouri and another former owner of the site entered into an agreement (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 Missouri Department of Natural Resources (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 located in the City 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 potentially responsible parties (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. Pending MDNR approval, which has not occurred to date, the remedial investigation of the site will begin. 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 the 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 is requesting more information from the EPA, some of which will 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 the MGP sites. While some of the insurers have denied coverage and reserved their rights, Spire Missouri continues to discuss potential reimbursements with them. On March 10, 2015, Spire Missouri received a Section 104(e) information request 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: 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 Spire Missouri 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, the successful completion of remediation efforts required by the Remediation Agreement described above, 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. Costs associated with environmental remediation activities are accrued when such costs are probable and reasonably estimable. To the extent such costs (less any amounts received from insurance proceeds or as contributions from other PRPs) are incurred prior to a rate case, Spire Missouri would request from the MoPSC authority to defer such costs and collect them in the next rate case. 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 nine 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 conditions 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. On December 17, 2013, an incident occurred at a Housing Authority apartment complex in Birmingham, Alabama that resulted in one fatality, personal injuries and property damage. Spire Alabama cooperated with the National Transportation Safety Board (NTSB) which investigated the incident. The NTSB report of findings was issued on March 30, 2016 and no safety recommendations, fines, or penalties were contained therein. Spire Alabama has been named as a defendant in several lawsuits arising from the incident, and additional lawsuits and claims may be filed against Spire Alabama. |

Accounting Policies [Abstract] | |
BASIS OF PRESENTATION | BASIS OF PRESENTATION – These notes are an integral part of the accompanying audited financial statements of Spire Inc. presented on a consolidated basis (Spire or the Company), 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 the Company. Spire Missouri changed its name from Laclede Gas Company on August 30, 2017, and Spire Alabama changed its name from Alabama Gas Corporation on September 1, 2017. Spire Missouri, Spire Alabama and the subsidiaries of Spire EnergySouth Inc. (formerly known as EnergySouth, Inc.) are collectively referred to as the Utilities. The subsidiaries of Spire EnergySouth Inc. (Spire EnergySouth) are Spire Gulf Inc. (Spire Gulf, formerly known as Mobile Gas Service Corporation) and Spire Mississippi Inc. (Spire Mississippi, formerly known as Willmut Gas & Oil Company). The accompanying audited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). Unless otherwise indicated, references to years herein are references to the fiscal years ending September 30 for the Company and its subsidiaries. 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 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. The Company’s September 12, 2016 acquisition of Spire EnergySouth is included in the results of operations since the acquisition date and impacts the comparability of the financial statement periods presented for the Company. For a further discussion of the acquisition, see Note 2 , Acquisitions. The Utilities are regulated natural gas distribution utilities. Due to the seasonal nature of the Utilities, the earnings of Spire, Spire Missouri and Spire Alabama are typically concentrated during the heating season of November through April each fiscal year. |
USE OF ESTIMATES | USE OF ESTIMATES – The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. |
SYSTEM OF ACCOUNTS | SYSTEM OF ACCOUNTS – The accounts of the Utilities are maintained in accordance with the Uniform System of Accounts prescribed by the applicable state public service commissions, which systems substantially conform to that prescribed by the Federal Energy Regulatory Commission (FERC). |
UTILITY PLANT, DEPRECIATION AND AMORTIZATION | PLANT, AND EQUIPMENT – Utility Plant – Utility plant is stated at original cost. The cost of additions to utility plant includes contracted work, direct labor and materials, allocable overheads, and an allowance for funds used during construction. The costs of units of property retired, replaced, or renewed are removed from utility plant and are charged to accumulated depreciation. Maintenance and repairs of property and replacement and renewal of items determined to be less than units of property are charged to maintenance expenses. For Spire Missouri, utility plant is depreciated on a straight-line basis at rates based on estimated service lives of the various classes of property. In fiscal years 2017 , 2016 and 2015 , annual depreciation and amortization expense averaged 3.0% of the original cost of depreciable and amortizable property. For Spire Alabama, depreciation is provided using the composite method of depreciation on a straight-line basis over the estimated useful lives of utility property at rates approved by the Alabama Public Service Commission (APSC). |
ASSET RETIREMENT OBLIGATIONS | ASSET RETIREMENT OBLIGATIONS – Spire, Spire Missouri, and Spire Alabama record legal obligations associated with the retirement of long-lived assets in the period in which the obligations are incurred, if sufficient information exists to reasonably estimate the fair value of the obligations. Obligations are recorded as both a cost of the related long-lived asset and as a corresponding liability. Subsequently, the asset retirement costs are depreciated over the life of the asset and the asset retirement obligations are accreted to the expected settlement amounts. The Company, Spire Missouri and Spire Alabama record asset retirement obligations associated with certain safety requirements to purge and seal gas distribution mains upon retirement, the plugging and abandonment of storage wells and other storage facilities, specific service line obligations, and certain removal and disposal obligations related to components of Spire Missouri’s, Spire Alabama’s and Spire Gulf’s distribution systems and general plant. Asset retirement obligations recorded by Spire’s other subsidiaries are not material. As authorized by the Missouri Public Service Commission (MoPSC) and APSC, Spire Missouri, Spire Alabama and Spire Gulf accrue future asset removal costs associated with their property, plant and equipment even if a legal obligation does not exist. Such accruals are provided for through depreciation expense and are recorded with corresponding credits to regulatory liabilities or regulatory assets. When those utilities retire depreciable utility plant and equipment, they charge the associated original costs to accumulated depreciation and amortization, and any related removal costs incurred are charged to regulatory liabilities or regulatory assets. The difference between removal costs recognized in depreciation rates and the accretion expense and depreciation expense recognized for financial reporting purposes is a timing difference between recovery of these costs in rates and their recognition for financial reporting purposes. Accordingly, these differences are deferred as regulatory liabilities or regulatory assets. In the rate setting process, the regulatory liabilities or regulatory assets are excluded from the rate base upon which those utilities have the opportunity to earn their allowed rates of return. The costs associated with asset retirement obligations of Spire Missouri, Spire Alabama and Spire Gulf are either currently being recovered in rates or are probable of recovery in future rates. |
REGULATED OPERATIONS | REGULATED OPERATIONS – The Utilities account for their regulated operations in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (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. See additional discussion on regulated operations in Note 15 , Regulatory Matters. As discussed below for Spire Missouri and Spire Alabama, 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 regulatory liabilities related to the PGA clauses and the GSA rider are both labeled Unamortized Purchased Gas Adjustments herein. Spire Missouri As authorized by the MoPSC, the PGA clause allows Spire Missouri to flow through to customers, subject to prudence review by the MoPSC, the cost of purchased gas supplies. To better match customer billings with market natural gas prices, Spire Missouri is allowed to file to modify, on a periodic basis, the level of gas costs in its PGA. Certain provisions of the PGA clause are included below: • Spire Missouri has a risk management policy that allows for the purchase of natural gas derivative instruments with the goal of managing price risk associated with purchasing natural gas on behalf of its customers. The MoPSC clarified that costs, cost reductions, and carrying costs associated with the Utility’s use of natural gas derivative instruments are gas costs recoverable through the PGA mechanism. • The tariffs allow Spire Missouri flexibility to make up to three discretionary PGA changes during each year, in addition to its mandatory November PGA change, so long as such changes are separated by at least two months . • Spire Missouri is authorized to apply carrying costs to all over- or under-recoveries of gas costs, including costs and cost reductions associated with the use of derivative instruments, including cash payments for margin deposits. Spire Missouri East is also authorized to recover gas inventory carrying costs through its PGA rates to recover costs it incurs to finance its investment in gas supplies that are purchased during the storage injection season for sale during the heating season. • The MoPSC approved a plan applicable to Spire Missouri’s gas supply commodity costs under which it retains a portion of cost savings associated with the acquisition of natural gas below an established benchmark level. This gas supply cost management program allows Spire Missouri to retain 10% of cost savings, up to a maximum of $3.0 annually. Spire Missouri did not record any such incentive compensation under the plan during the three fiscal years reported. Incentives recorded under the plan, if any, are included in Gas Utility Operating Revenues on the Consolidated Statements of Income and under Operating Revenues on Spire Missouri’s Statements of Income. Pursuant to the provisions of the PGA clause, the difference between actual costs incurred and costs recovered through the application of the PGA clause are reflected as a deferred charge or credit at the end of the fiscal year. These costs include costs and cost reductions associated with the use of derivative instruments and gas inventory carrying costs, amounts due to or from customers related to operation of the gas supply cost management program, refunds received from the Company’s suppliers in connection with gas supply, transportation, and storage services, and carrying costs on such over- or under-recoveries. At that time, the balance is classified as a current asset or current liability and recovered from, or credited to, customers over an annual period commencing in November. The balance in the current account is amortized as amounts are reflected in customer billings. The PGA clause also provides for the treatment of income from off-system sales and capacity release revenues. Pre-tax income from off-system sales and capacity release revenues is shared with customers, with an estimated amount assumed in PGA rates. The difference between the actual amount allocated to customers for each fiscal year and the estimated amount assumed in PGA rates is recovered from, or credited to, customers over an annual period commencing in the subsequent November. The customer share of such income is determined in accordance with the following tables, shown for each service territory for which the PGA clauses were approved by the MoPSC. Customer Share Company Share Spire Missouri East First $2.0 of pre-tax income* 85% 15% Next $2.0 of pre-tax income 80% 20% Next $2.0 of pre-tax income 75% 25% Amounts of pre-tax income exceeding $6.0 70% 30% * Customer share was set to 85% and company share set to 15% in fiscal 2017. For fiscal 2016 and 2015, the customer share and company share were 100% and 0%, respectively. Spire Missouri West First $1.2 of pre-tax income 85% 15% Next $1.2 of pre-tax income 80% 20% Next $1.2 of pre-tax income 75% 25% Amounts of pre-tax income exceeding $3.6 70% 30% Spire Alabama Spire Alabama’s rate schedules for natural gas distribution charges contain a GSA rider, established in 1993, which permits the pass-through to customers of changes in the cost of gas supply. Spire Alabama’s tariff provides a temperature adjustment mechanism, also included in the GSA rider, which is designed to moderate the impact of departures from normal temperatures on Spire Alabama’s earnings. The temperature adjustment applies primarily to residential, small commercial and small industrial customers. Other non-temperature weather-related conditions that may affect customer usage are not included in the temperature adjustment. |
NATURAL GAS AND PROPANE GAS | NATURAL GAS AND PROPANE GAS – For Spire Missouri East, inventory of natural gas in storage is priced on a last in, first out (LIFO) basis and inventory of propane gas in storage is priced on a first in, first out (FIFO) basis. For the rest of the Gas Utility segment, inventory of natural gas in storage is priced on the weighted average cost basis. The replacement cost of Spire Missouri’s natural gas for current use in eastern Missouri at September 30, 2017 and September 30, 2016 was less than the LIFO cost by $20.8 and $11.4 , respectively. The carrying value of the Utilities’ inventory is not adjusted to the lower of cost or market prices because, pursuant to PGA or GSA, actual gas costs are recovered in customer rates. Natural gas and propane gas storage inventory in Spire’s other operating segments is recorded at the lower of average cost or market. |
BUSINESS COMBINATIONS | BUSINESS COMBINATIONS – The Spire EnergySouth acquisition was accounted for by Spire using business combination accounting. Under this method, the purchase price paid by the acquirer is allocated to the assets acquired and liabilities assumed as of the acquisition date based on their fair value. |
GOODWILL | 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. Spire and Spire Missouri evaluate goodwill for impairment as of July 1 of each year, or more frequently if events and circumstances indicate that goodwill might be impaired. At July 1, 2017, 2016 and 2015, Spire and Spire Missouri each applied a quantitative goodwill evaluation model to their reporting units and concluded goodwill was not impaired because the fair value exceeded the carrying amount. |
IMPAIRMENT OF LONG-LIVED ASSETS | IMPAIRMENT OF LONG-LIVED ASSETS – Long-lived assets classified as held and used are evaluated for impairment when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. Whether impairment has occurred is determined by comparing the estimated undiscounted cash flows attributable to the assets with the carrying value of the assets. If the carrying value exceeds the undiscounted cash flows, the Company recognizes an impairment charge equal to the amount of the carrying value that exceeds the estimated fair value of the assets. In the period in which the Company determines an asset meets held-for-sale criteria, an impairment charge is recorded to the extent the book value exceeds its fair value less cost to sell. |
REVENUE RECOGNITION | REVENUE RECOGNITION – The Utilities read meters and bill customers on monthly cycles. The Missouri Utilities, Spire Gulf and Spire Mississippi 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 Spire Missouri at September 30, 2017 and 2016 were $30.1 and $26.1 , respectively. Spire Alabama records natural gas distribution revenues in accordance with the tariff established by the APSC. Unbilled revenue is accrued in an amount equal to the related gas cost, as profit margin is not considered earned until billed. The amounts of accrued unbilled revenues for Spire Alabama at September 30, 2017 and 2016 were $1.9 and $5.9 . 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 its derivative natural gas contracts are designated as normal purchases or normal sales and, as such, are excluded from the scope of 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. For additional information on derivative instruments, refer to Note 10 , Derivative Instruments and Hedging Activities. 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 Consolidated Statements of Income. This net presentation has no effect on operating income or net income. |
INCOME TAXES | INCOME TAXES – Spire and its subsidiaries account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amount of existing assets and liabilities and the respective tax basis and for tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effects on deferred tax assets and liabilities of a change in enacted tax rates is recognized in income or loss for a non-regulated company, and in a regulatory asset or regulatory liability for a regulated company. A valuation allowance is established when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company accounts for uncertain tax positions in accordance with authoritative guidance. The authoritative guidance addresses the determination of whether tax benefits claimed, or expected to be claimed, on a tax return should be recorded in the financial statements. Spire may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the position will be sustained upon examination by the taxing authority, based on the technical merits of the position. Tax-related interest and penalties, if any, are classified as a liability on the balance sheets. |
CASH AND CASH EQUIVALENTS | CASH AND CASH EQUIVALENTS – All highly liquid debt instruments purchased with original maturities of three months or less are considered to be cash equivalents. Such instruments are carried at cost, which approximates market value. Outstanding checks on the Company’s and Utilities’ bank accounts in excess of funds on deposit create book overdrafts (which are funded at the time checks are presented for payment) and are classified as Other in the Current Liabilities section of the balance sheets. Changes in book overdrafts are reflected as Operating Activities in the statements of cash flows. |
NATURAL GAS RECEIVABLE | NATURAL GAS RECEIVABLE – Spire Marketing enters into natural gas transactions with natural gas pipeline companies known as park and loan arrangements. Under the terms of the arrangements, Spire Marketing purchases natural gas from a third party and delivers that natural gas to the pipeline company for the right to receive the same quantity of natural gas from the pipeline company at the same location in a future period. These arrangements are accounted for as non-monetary transactions under GAAP and are recorded at the carrying amount. As such, natural gas receivables are reflected on the Consolidated Balance Sheets at cost, which includes related pipeline fees associated with the transactions. In the period that the natural gas is returned to Spire Marketing, concurrent with the sale of the natural gas to a third party, the related natural gas receivable is expensed in the Consolidated Statements of Income. In conjunction with these transactions, Spire Marketing usually enters into New York Mercantile Exchange (NYMEX) and Intercontinental Exchange (ICE) natural gas futures, options, and swap contracts or fixed price sales agreements to protect against market changes in future sales prices. ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS – Trade accounts receivable are recorded at the amounts due from customers, including unbilled amounts. Estimates of the collectability of trade accounts receivable are based on historical trends, age of receivables, economic conditions, credit risk of specific customers, and other factors. Accounts receivable are written off against the allowance for doubtful accounts when they are deemed to be uncollectible. Spire’s provision for uncollectible accounts includes the amortization of previously deferred uncollectible expenses for Spire Missouri and Spire Alabama, as approved by the MoPSC and the APSC |
EARNINGS PER COMMON SHARE | EARNINGS PER COMMON SHARE – GAAP requires dual presentation of basic and diluted earnings per share (EPS). EPS is computed using the two-class method, which is an earnings allocation method for computing EPS that treats a participating security as having rights to earnings that would otherwise have been available to common shareholders. Certain of the Company’s stock-based compensation awards pay non-forfeitable dividends to the participants during the vesting period and, as such, are deemed participating securities. Basic EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding that are increased for additional shares that would be outstanding if potentially dilutive non-participating securities were converted to common shares, pursuant to the treasury stock method. Shares attributable to equity units, non-participating stock options and time-vested restricted stock/units are excluded from the calculation of diluted earnings per share if the effect would be antidilutive. Shares attributable to non-participating performance-contingent restricted stock awards are only included in the calculation of diluted earnings per share to the extent the underlying performance and/or market conditions are satisfied (a) prior to the end of the reporting period or (b) would be satisfied if the end of the reporting period were the end of the related contingency period and the result would be dilutive. |
GROSS RECEIPTS AND SALES TAXES | GROSS RECEIPTS AND SALES TAXES – Gross receipts taxes associated with the Company’s natural gas utility services are imposed on the Company, Spire Missouri, and Spire Alabama and billed to its 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: 2017 2016 2015 Spire $ 84.6 $ 75.5 $ 97.3 Spire Missouri 60.7 57.4 74.5 Spire Alabama 19.5 17.9 22.6 Sales taxes imposed on applicable Spire Alabama and Spire Missouri sales are billed to customers. These amounts are not recorded in the statements of income but are recorded as tax collections payable and included in the “Other” line of the Current Liabilities section of the balance sheets. |
TRANSACTIONS WITH AFFILIATES | TRANSACTIONS WITH AFFILIATES – Transactions between affiliates of the Company have been eliminated from the consolidated financial statements of Spire. |
GROUP MEDICAL AND WORKERS' COMPENSATION RESERVES | GROUP MEDICAL AND WORKERS’ COMPENSATION RESERVES – The Company self-insures its group medical and workers’ compensation costs and carries stop-loss coverage in relation to medical claims and workers’ compensation claims. Reserves for amounts incurred but not reported are established based on historical cost levels and lags between occurrences and reporting. |
FAIR VALUE MEASUREMENTS | FAIR VALUE MEASUREMENTS – Certain assets and liabilities are recognized or disclosed at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). GAAP establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The levels of the hierarchy are described below: • Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2 – Pricing inputs other than quoted prices included within Level 1, which are either directly or indirectly observable for the asset or liability as of the reporting date. These inputs are derived principally from, or corroborated by, observable market data. • Level 3 – Pricing that is based upon inputs that are generally unobservable that are based on the best information available and reflect management’s assumptions about how market participants would price the asset or liability. Assessment of the significance of a particular input to the fair value measurements may require judgment and may affect the valuation of the asset or liability and its placement within the fair value hierarchy. |
STOCK-BASED COMPENSATION | STOCK-BASED COMPENSATION – The Company measures stock-based compensation awards at fair value at the date of grant and recognizes the compensation cost of the awards over the requisite service period. Effective with the adoption of Accounting Standards Update No. 2016-09 at the beginning of fiscal 2017 (described under New Accounting Pronouncements below), forfeitures are recognized in the period they occur. In fiscal 2016 and fiscal 2015, forfeitures were estimated at the time of grant and revised, when necessary, in subsequent periods when the actual forfeitures differed from those estimates. |
NEW ACCOUNTING STANDARDS | NEW ACCOUNTING PRONOUNCEMENTS – 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. Spire, Spire Missouri and Spire Alabama adopted this ASU as of December 31, 2016. Retrospective adjustments have been made to the previous year balance sheets as of September 30, 2016, and the amounts of unamortized debt issuance costs are shown separately on the statements of capitalization. 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. |

Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Line Items] | |
Fair Value Measurements, 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. The mutual funds included in Level 2 are valued based on the closing net asset value per unit. Derivative instruments included in Level 1 are valued using quoted market prices on the NYMEX. Derivative instruments classified as Level 2 include physical commodity derivatives that are valued using Over-the-Counter Bulletin Board (OTCBB), 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. There were no material Level 3 balances as of September 30, 2017 or 2016 . 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 “Property and other investments” on Spire Missouri’s balance sheets. Derivative assets and liabilities, including receivables and payables associated with cash margin requirements, are presented net on the balance sheets when a legally enforceable netting agreement exist between the Company or Spire Missouri and the counterparty to the derivative contract.
