Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Preparation and Nature of Operations	Description of Business HRG Group, Inc. (“HRG”, and collectively with its respective subsidiaries, the “Company”) is a holding company that conducts its operations principally through its majority owned subsidiary, Spectrum Brands Holdings, Inc., which is a diversified global branded consumer products company (“Spectrum Brands”). HRG’s shares of common stock trade on the New York Stock Exchange (“NYSE”) under the symbol “HRG.” The Company’s reportable business segments are organized in a manner that reflects how HRG’s management views those business activities. Accordingly, the Company currently presents the results from its business operations in two reportable segments: (i) Consumer Products and (ii) Corporate and Other. The Company’s Consumer Products segment represents the Company’s 59.3% controlling interest in Spectrum Brands. The Company’s Corporate and Other segment includes the Company’s ownership of Salus Capital Partners, LLC, (“Salus”), which was created for the purpose of serving as an asset-based lender and is in the process of completing the wind-down of its business, 99.5% of NZCH Corporation (“NZCH”), a public shell company, HGI Funding, LLC (“HGI Funding”) and HGI Energy Holdings, LLC (“HGI Energy”), which are subsidiaries that the Company uses to manage a portion of its available cash and engage in other activities. For the results of operations by segment, and other segment data, see Note 18, Segment Data and Note 20, Consolidating Financial Information. Consumer Products Segment The Consumer Products segment represents the Company’s 59.3% controlling interest in Spectrum Brands. Through its operating subsidiaries, Spectrum Brands is a diversified global branded consumer products company with positions in multiple product lines and categories: consumer batteries, small appliances, global pet supplies, home and garden control products, personal care products, hardware and home improvement products and global auto care. Effective December 29, 2017, Spectrum Brands’ Board of Directors approved a plan to explore strategic alternatives, including the planned sale of Spectrum Brands’ Global Batteries & Appliances (“GBA”) segment. Spectrum Brands expects a sale to be realized by December 31, 2018. See Note 3, Divestitures, regarding Spectrum Brands’ agreement to sell its Global Batteries and Lighting (“GBL”) business and its plans to sell its Home and Personal Care (“HPC”) business. The Company reports a business as held for sale when the criteria of Accounting Standard Codification (“ASC”) Topic 360, Property, Plant and Equipment (“ASC 360”) are met. The Company believes ASC 360’s criteria for the GBA segment have been met as of December 31, 2017. As a result, Spectrum Brands’ assets and liabilities associated with the GBA segment have been classified as held for sale in the accompanying Condensed Consolidated Balance Sheets and the respective operations of the GBA segment have been classified as discontinued operations in the accompanying Condensed Consolidated Statements of Operations and Condensed Consolidated Statements of Cash Flows; and reported separately for all periods presented. See Note 2, Significant Accounting Policies and Recent Accounting Pronouncements- Assets Held for Sale and Discontinued Operations. See Note 3, Divestitures for more information on the assets and liabilities classified as held for sale and discontinued operations. See Note 18, Segment Data for more information pertaining to segments of continuing operations. Corporate and Other Segment On November 30, 2017, Fidelity & Guaranty Life (“FGL”), a former majority owned subsidiary of the Company, completed its merger (the “FGL Merger”) with CF Corporation and its related entities (collectively, the “CF Entities”) pursuant to its previously disclosed Agreement and Plan of Merger (the “FGL Merger Agreement”). Pursuant to the FGL Merger Agreement, except for certain shares specified in the FGL Merger Agreement, each issued and outstanding share of common stock of FGL was automatically cancelled and converted into the right to receive $31.10 in cash. In addition, pursuant to a share purchase agreement, on November 30, 2017, Front Street Re (Delaware) Ltd., a wholly-owned subsidiary of HRG, sold to the CF Entities (such sale, the “Front Street Sale”) all of the issued and outstanding shares of its former wholly-owned subsidiaries, Front Street Re Cayman Ltd. and Front Street Re Ltd (collectively, “Front Street”, and together with FGL, the “Insurance Operations”). The purchase price for the Front Street Sale was $65.0, subject to reduction for customary transaction expenses. In addition, $6.5 of the purchase price was deposited in escrow for a period of 15 months to support any indemnification claims that might be made (if any) by the CF Entities. Pursuant to the share purchase agreement, on December 5, 2017, the Company repaid the $92.0 of notes (such notes, the “HGI Energy Notes”) issued by HGI Energy, which were held directly and indirectly by Front Street and FGL. Following the completion of the FGL Merger and the Front Street Sale, HRG no longer has any equity interest in FGL or Front Street and our former Insurance Operations segment is presented as discontinued operations for prior periods. HRG deconsolidated FGL and Front Street as of November 30, 2017. Finally, as previously disclosed, HRG, FS Holdco II Ltd. (“FS Holdco”) and the CF Entities entered into an agreement (the “338 Agreement”) on May 24, 2017 pursuant to which the CF Entities agreed that FS Holdco may, at its option, cause the relevant CF Entity and FS Holdco to make a joint election under Section 338(h)(10) of the Internal Revenue Code of 1986, as amended, with respect to the FGL Merger and the deemed share purchases of FGL’s subsidiaries (the “338 Tax Election”). Pursuant to the 338 Agreement, if FS Holdco elects to make the 338 Tax Election, FS Holdco and/or CF Corporation will be required to make a payment for the election to the other. As of December 31, 2017, HRG expects to receive an estimated $26.6 net payment from CF Corporation, which has been included in the estimated consideration HRG expects to receive from the FGL Merger. Pursuant to the 338 Agreement, FS Holdco may elect to exercise the 338 Tax Election at any time until 10 business days after final calculation of such incremental tax costs or savings, as the case may be, and it currently expects to exercise such election within such period. Nonetheless, there can be no assurance that FS Holdco will make the election and/or that HRG will receive the expected benefits of such election. In addition, the estimated payment described herein is preliminary as of December 31, 2017 and subject to change, and HRG does not undertake any obligation to update such estimate. Also on December 15, 2017, HRG issued a notice of redemption to redeem all $864.4 outstanding principal amount of its 7.875% Senior Secured Notes due 2019 (the “7.875% Notes”) at a redemption price equal to 100.0% of the principal amount thereof, plus accrued and unpaid interest to the redemption date. The 7.875% Notes were redeemed on January 16, 2018. In addition, we continued to streamline our business and simplify our holding company structure and also continued to review and evaluate strategic alternatives available to us with a view towards maximizing shareholder value. We believe that HRG is an excellent company that owns great businesses that have generated strong performance over a long period of time. We believe that we are well-positioned to take advantage of the opportunities that may be available to us through the review of strategic alternatives. Strategic alternatives may include, but are not limited to, a merger, sale or other business combination involving the Company and/or its assets. As part of this strategic review process, HRG has made/received, and may in the future make/receive, one or more proposals to/from third parties and/or Spectrum Brands, its management, its board of directors, its stockholders and other persons, including discussions and proposals that may include, but are not limited to, a merger or a sale and/or a business combination of the Company and Spectrum Brands. In connection therewith, the Spectrum Brands board of directors has formed a special committee of independent directors and has hired independent financial and legal advisors. We have not set a definitive schedule to complete our review of strategic alternatives and do not intend to provide any further updates until such time as it determines in its sole discretion or as required by law. The strategic review process may be suspended or terminated at any time without notice. There can be no assurance that any such process will result in a transaction, or if a transaction is undertaken, as to its terms or timing. Basis of Presentation The unaudited Condensed Consolidated Financial Statements of the Company included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of such information. All such adjustments are of a normal recurring nature. Although the Company believes that the disclosures are adequate to make the information presented not misleading, certain information and note disclosures, including a description of significant accounting policies normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), have been condensed or omitted pursuant to such rules and regulations. As of December 31, 2017, the Company changed its method of presenting its financial statements from an unclassified balance sheet in accordance with Article 7, Insurance Companies, and Regulation S-X to a classified balance sheet. The Company believes a classified balance sheet is preferable as a result of the completion of the FGL Merger and Front Street Sale. Certain prior amounts have been reclassified or combined to conform to the current year presentation. These reclassifications and combinations had no effect on previously reported net income attributable to controlling interest or accumulated deficit. These interim financial statements should be read in conjunction with the Company’s annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2017, filed with the SEC on November 20, 2017 (the “Form 10-K”). The results of operations for the three months ended December 31, 2017 are not necessarily indicative of the results for any subsequent periods or the entire fiscal year ending September 30, 2018. The Company’s fiscal year ends on September 30 and the quarters end on the last calendar day of the months of December, March and June. Spectrum Brands’ fiscal year ends September 30 and its interim fiscal quarters end every thirteenth Sunday, except for its first fiscal quarter which may end on the fourteenth Sunday following September 30. The Company does not adjust for the difference in fiscal periods between Spectrum Brands and itself, as such difference would be less than 93 days, pursuant to Regulation S-X Rule 3A-02. At December 31, 2017, the non-controlling interest component of total equity primarily represents the 40.7% share of Spectrum Brands not owned by HRG.

Accounting Policies [Abstract]
Significant Accounting Policies and Practices and Recent Accounting Pronouncements	Assets Held for Sale and Discontinued Operations A business classified as held for sale is recorded at the lower of its carrying amount or estimated fair value less cost to sell. If the carrying amount of the business exceeds its estimated fair value less cost to sell, a loss is recognized. Assets and liabilities related to a business classified as held for sale are segregated in the current and prior balance sheets in the period in which the business is classified as held for sale. Transactions between the business held for sale and businesses held for use that are expected to continue to exist after the disposal are not eliminated to appropriately reflect the continuing operations and balances held for sale. If a business is classified as held for sale after the balance sheet date but before the financial statements are issued or are available to be issued, the business continues to be classified as held and used in those financial statements when issued or when available to be issued. The Company reports the results of operations of a business as discontinued operations if a disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results when the business is sold or classified as held for sale, in accordance with ASC 360 and Accounting Standards Update (“ASU”) No. 2014-08, Presentation of Financial Statements (Topic 2015) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (“ASU 2014-08”). The results of discontinued operations are reported in “Income from discontinued operations, net of tax” in the accompanying Condensed Consolidated Statements of Operations for current and prior periods commencing in the period in which the business meets the criteria of a discontinued operation, and include any gain or loss recognized on closing or adjustment of the carrying amount to fair value less cost to sell. Transactions between the businesses held for sale and businesses held for use that are expected to continue to exist after the disposal are not eliminated to appropriately reflect the continuing operations and balances held for sale. Use of Estimates and Assumptions The preparation of the Company’s Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and assumptions used. Recent Accounting Pronouncements Not Yet Adopted The Company has implemented all new accounting pronouncements that are in effect and that may impact its Condensed Consolidated Financial Statements and does not believe that there are any other new accounting pronouncements, other than the ones disclosed in the Company’s Form 10-K, that have been issued that might have a material impact on its financial condition, results of operations or liquidity.

In accordance with ASC 360, Property, Plant and Equipment, long-lived assets classified as held for sale are measured at the lower of their carrying value or fair value less cost to sell at the balance sheet date. At September 30, 2017, the carrying value of the Company’s interest in FGL and Front Street exceeded their respective estimated fair value less cost to sell by $402.2 and $19.0, respectively.

The higher carrying value of FGL was primarily due to the increase in unrealized gains, net of offsets in FGL’s investment portfolio, with the effects of the unrealized gains, net of offsets, being recorded in accumulated other comprehensive income (“AOCI”). Upon the completion of the FGL Merger, the Company deconsolidated its ownership interest in FGL, which resulted in the reclassification of $445.9 of AOCI attributable to FGL to income from discontinued operations during the three months ended December 31, 2017.

In particular, Spectrum Brands has agreed to indemnify Energizer for certain liabilities relating to the assets retained by Spectrum Brands, and Energizer has agreed to indemnify Spectrum Brands for certain liabilities assumed by Energizer, in each case as described in the GBL Sale Agreement.

(11) Derivative Financial Instruments

Cash Flow Hedges

Interest Rate Swaps. Spectrum Brands uses interest rate swaps to manage its interest rate risk. The swaps are designated as cash flow hedges with the changes in fair value recorded in AOCI and as a derivative hedge asset or liability, as applicable. The swaps settle periodically in arrears with the related amounts for the current settlement period payable to, or receivable from, the counterparties included in accrued liabilities or receivables, respectively, and recognized in earnings as an adjustment to interest from the underlying debt to which the swap is designated. At December 31, 2017 and September 30, 2017, Spectrum Brands had a series of U.S. dollar denominated interest rate swaps outstanding which effectively fix the interest on floating rate debt, exclusive of lender spreads, at 1.76% for a notional principal amount of $300.0 through May 2020. The derivative net gain estimated to be reclassified from AOCI into earnings over the next 12 months is $0.1, net of tax. Spectrum Brands’ interest rate swaps financial instruments at December 31, 2017 and September 30, 2017 were as follows:



	December 31, 2017			September 30, 2017
	Notional Amount		Remaining Years	Notional Amount		Remaining Years
Interest rate swaps - fixed	$	300.0	2.3	$	300.0	2.6

Commodity Swaps. Spectrum Brands is exposed to risk from fluctuating prices for raw materials, specifically brass used in its manufacturing processes. Spectrum Brands hedges a portion of the risk associated with the purchase of these materials through the use of commodity swaps. The hedge contracts are designated as cash flow hedges with the fair value changes recorded in AOCI and as a hedge asset or liability, as applicable. The unrecognized changes in fair value of the hedge contracts are reclassified from AOCI into earnings when the hedged purchase of raw materials also affects earnings. The swaps effectively fix the floating price on a specified quantity of raw materials through a specified date. At December 31, 2017, Spectrum Brands had a series of brass swap contracts outstanding through June 2019. The derivative net gains estimated to be reclassified from AOCI into earnings over the next 12 months is $0.4, net of tax. Spectrum Brands had the following commodity swap contracts outstanding as of December 31, 2017 and September 30, 2017:

Foreign exchange contracts. Spectrum Brands periodically enters into forward foreign exchange contracts to hedge a portion of the risk from forecasted foreign currency denominated third party and intercompany sales or payments. These obligations generally require Spectrum Brands to exchange foreign currencies for U.S. Dollars, Euros, Canadian Dollars (“CAD”) or Japanese Yen. These foreign exchange contracts are cash flow hedges of fluctuating foreign exchange rates related to sales of product or raw material purchases. Until the sale or purchase is recognized, the fair value of the related hedge is recorded in AOCI and as a derivative hedge asset or liability, as applicable. At the time the sale or purchase is recognized, the fair value of the related hedge is reclassified as an adjustment to “Net sales” or purchase price variance in “Cost of goods sold”, respectively, in the accompanying Condensed Consolidated Statements of Operations. At December 31, 2017, Spectrum Brands had a series of foreign exchange derivative contracts outstanding through August 2019. The derivative net gains estimated to be reclassified from AOCI into earnings over the next 12 months is $0.5, net of tax. At December 31, 2017 and September 30, 2017, Spectrum Brands had foreign exchange derivative contracts designated as cash flow hedges with a notional value of $53.2 and $67.5, respectively.

Net Investment Hedge

On September 20, 2016, SBI issued €425.0 aggregate principal amount of 4.00% Notes due October 1, 2026 (“4.00% Notes”). Spectrum Brands’ 4.00% Notes are denominated in Euros and have been designated as a net investment hedge of the translation of Spectrum Brands’ net investments in Euro denominated subsidiaries at the time of issuance. As a result, the translation of the Euro denominated debt is recognized in AOCI with any ineffective portion recognized as foreign currency translation gains or losses in the accompanying Condensed Consolidated Statements of Operations when the aggregate principal exceeds the net investment in its Euro denominated subsidiaries. Net gains or losses from the net investment hedge are reclassified from AOCI into earnings upon a liquidation event or deconsolidation of Euro denominated subsidiaries. As of December 31, 2017, the hedge was fully effective and no ineffective portion was recognized in earnings.

Derivative Contracts Not Designated as Hedges for Accounting Purposes

Foreign exchange contracts. Spectrum Brands periodically enters into forward and swap foreign exchange contracts to economically hedge a portion of the risk from third party and intercompany payments resulting from existing obligations. These obligations generally require Spectrum Brands to exchange foreign currencies for U.S. Dollars, CAD, Euros, Pounds Sterling, Taiwanese Dollars, Hong Kong Dollars or Australian Dollars. These foreign exchange contracts are fair value hedges of a related liability or asset recorded in the accompanying Condensed Consolidated Balance Sheets. The gain or loss on the derivative hedge contracts is recorded in earnings as an offset to the change in value of the related liability or asset at each period end. At December 31, 2017, Spectrum Brands had a series of forward exchange contracts outstanding through January 2018. At December 31, 2017 and September 30, 2017, Spectrum Brands had $90.5 and $62.9, respectively, of notional value of such foreign exchange derivative contracts outstanding.

Spectrum Brands is exposed to the risk of default by the counterparties with which Spectrum Brands transacts and generally does not require collateral or other security to support financial instruments subject to credit risk. Spectrum Brands monitors counterparty credit risk on an individual basis by periodically assessing each counterparty’s credit rating exposure. The maximum loss due to credit risk equals the fair value of the gross asset derivatives that are concentrated with certain domestic and foreign financial institution counterparties. Spectrum Brands considers these exposures when measuring its credit reserve on its derivative assets, which was less than $0.1 as of December 31, 2017 and September 30, 2017.

Spectrum Brands’ standard contracts do not contain credit risk related contingent features whereby Spectrum Brands would be required to post additional cash collateral as a result of a credit event. However, Spectrum Brands is typically required to post collateral in the normal course of business to offset its liability positions. As of December 31, 2017 and September 30, 2017, there was no cash collateral outstanding. In addition, as of December 31, 2017 and September 30, 2017, Spectrum Brands had no posted standby letters of credit related to such liability positions.

The following tables summarize the impact of derivative instruments in the accompanying Condensed Consolidated Statements of Operations for the three months ended December 31, 2017 and 2016, pre-tax:

Fair Value of Financial Instruments

3 Months Ended

Dec. 31, 2017

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Spectrum Brands utilizes valuation techniques that attempt to maximize the use of observable inputs and minimize the use of unobservable inputs. Spectrum Brands’ derivative assets and liabilities are valued on a recurring basis using internal models, which are based on market observable inputs including interest rate curves and both forward and spot prices for currencies and commodities, which are generally based on quoted or observed market prices and classified as Level 2. The fair value of certain derivatives is estimated using pricing models based on contracts with similar terms and risks. Modeling techniques assume market correlation and volatility, such as using prices of one delivery point to calculate the price of the contract’s different delivery point. The nominal value of interest rate transactions is discounted using applicable forward interest rate curves. In addition, by applying a credit reserve which is calculated based on credit default swaps or published default probabilities for the actual and potential asset value, the fair value of Spectrum Brands’ derivative assets reflects the risk that the counterparties to these contracts may default on the obligations. Likewise, by assessing the requirements of a reserve for non-performance which is calculated based on the probability of default by Spectrum Brands, it adjusts its derivative liabilities to reflect the price at which a potential market participant would be willing to assume Spectrum Brands’ liabilities. Spectrum Brands has not changed its valuation techniques in measuring the fair value of any derivative assets and liabilities during the quarter.

The Company’s consolidated assets and liabilities measured at fair value are summarized according to the hierarchy previously described as follows:



	December 31, 2017								September 30, 2017
	Level 1		Level 2		Level 3		Fair Value		Level 1		Level 2		Level 3		Fair Value
Derivative Assets	$	—	$	3.8	$	—	$	3.8	$	—	$	1.5	$	—	$	1.5
Derivative Liabilities	—		1.5		—		1.5		—		3.3		—		3.3

See Note 11, Derivative Financial Instruments, for additional detail.

Non-Recurring Fair Value Measurements

Goodwill, intangible assets and other long-lived assets are tested annually or more frequently if an event occurs that indicates an impairment loss may have been incurred using fair value measurements with unobservable inputs (Level 3).

Financial Assets and Liabilities Not Measured at Fair Value

The carrying amount, estimated fair value and the level of the fair value hierarchy of the Company’s financial instruments which are not measured at fair value in the accompanying Condensed Consolidated Balance Sheets are summarized as follows:



	December 31, 2017
	Level 1		Level 2		Level 3		Fair Value		Carrying Amount
Total debt	$	—	$	6,015.0	$	—	$	6,015.0	$	5,822.9



	September 30, 2017
	Level 1		Level 2		Level 3		Fair Value		Carrying Amount
Total debt	$	—	$	5,839.3	$	92.0	$	5,931.3	$	5,705.4

The carrying value of cash and cash equivalents, receivables and payables approximate fair value due to their short duration and, accordingly, they are not presented in the tables above. The fair value of debt set forth above is generally based on quoted or observed market prices.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Additional Disclosures

During the three months ended December 31, 2017, HRG’s stock option awards and HRG’s restricted stock awards with a total fair value of $2.7 vested. The total intrinsic value of HRG’s share options exercised during the three months ended December 31, 2017 was $0.5, for which HRG received cash of $1.4 in settlement.

Under HRG’s executive compensation plan for the three months ended December 31, 2017, executives will be paid in cash. In addition, at the discretion of the Board, executives may from time to time be granted stock, stock options, and shares of restricted stock.

As of December 31, 2017, HRG had $1.0 of total unrecognized compensation cost related to unvested share-based compensation agreements previously granted, which is expected to be recognized over a weighted-average period of 1.18 years.

The fair values of HRG’s restricted stock and restricted stock unit awards are determined based on the market price of HRG’s common stock on the grant date. The fair value of HRG’s stock option awards and warrants are determined using the Black-Scholes option pricing model.

The following assumptions were used in the determination of these grant date fair values for HRG’s options awarded using the Black-Scholes option pricing model:



	Three months ended December 31, 2016
Risk-free interest rate	1.80% to 2.25%
Assumed dividend yield	—%
Expected option term	5.0 to 6.5 years
Volatility	35.1% to 37.5%

There is no comparative in the table above as there were no options granted during the three months ended December 31, 2017.

The weighted-average remaining contractual term of HRG’s outstanding stock option awards and warrants at December 31, 2017, was 4.06 years.

Spectrum Brands measures share-based compensation expense of restricted stock units based on the fair value of the awards, as determined by the market price of the Spectrum Brands’ shares on the grant date and recognizes these costs on a straight-line basis over the requisite service period of the awards. Certain of Spectrum Brands’ restricted stock units are performance-based awards that are dependent upon achieving specified financial metrics over a designated period of time. In addition to restricted stock units, Spectrum Brands also provides for a portion of its annual management incentive compensation plan to be paid in common stock of Spectrum Brands, in lieu of cash payment, and is considered a liability plan.

The total market value Spectrum Brands’ restricted stock units on the dates of the grants was approximately $36.0. The remaining unrecognized pre-tax compensation cost related to restricted stock units at December 31, 2017 was $43.4.

Employee Benefit Obligations	3 Months Ended
Employee Benefit Obligations	Dec. 31, 2017
Compensation and Retirement Disclosure [Abstract]
Employee Benefit Obligations	Defined Benefit Plans HRG HRG has a noncontributory defined benefit pension plan (the “HRG Pension Plan”) covering certain of its former U.S. employees. During 2006, the HRG Pension Plan was frozen which caused all existing participants to become fully vested in their benefits. Additionally, HRG has an unfunded supplemental pension plan (the “Supplemental Plan”) which provides supplemental retirement payments to certain former senior executives of HRG. The amounts of such payments equal the difference between the amounts received under the HRG Pension Plan and the amounts that would otherwise be received if HRG Pension Plan payments were not reduced as the result of the limitations upon compensation and benefits imposed by Federal law. Effective December 1994, the Supplemental Plan was frozen. On November 15, 2017, the Company’s Board of Directors approved the termination of the HRG Pension Plan, which is a legacy plan. As of December 31, 2017 and September 30, 2017, the HRG Pension Plan’s projected benefit obligation was $15.4 and $15.6, respectively and the fair value of plan assets was $11.2 and $11.6, respectively. The HRG Pension Plan’s termination date is February 15, 2018. The Company expects to purchase annuity contracts in the third quarter of Fiscal 2018 to settle the Company’s obligations to the HRG Pension Plan’s participants. The Company accrued a $1.6 liability as of December 31, 2017 for the estimated additional cost to settle the HRG Pension Plan above the $4.2 unfunded benefit obligation amount.

Income Taxes	3 Months Ended
Income Taxes	Dec. 31, 2017
Income Taxes [Abstract]
Income Tax Disclosure [Text Block]	For the three months ended December 31, 2017, the Company’s effective tax rate of 263.0% differed from the expected U.S. statutory tax rate of 35.0% and was significantly impacted by the Tax Cuts and Jobs Act (the “Tax Reform Act”). The Tax Reform Act permanently reduces the U.S. corporate income tax rate from a maximum of 35.0% to a flat 21.0% rate, effective January 1, 2018. During the three months ended December 31, 2017, Spectrum Brands recorded a provisional $206.7 tax benefit for revaluation of U.S. deferred tax assets and liabilities and a provisional $78.8 of income tax expense for the one-time deemed mandatory repatriation. For the three months ended December 31, 2016, the Company’s effective tax rate of (15.4)% differed from the expected U.S. statutory tax rate of 35.0% and was impacted by U.S. pretax losses in the Company’s Corporate and Other segment where the tax benefits are not more-likely-than-not to be realized resulting in the recording of valuation allowance. HRG At December 31, 2017 and September 30, 2017, HRG had approximately $1,565.1 and $1,524.3, respectively, of gross U.S. Federal net operating loss (“NOL”) carryforwards (inclusive of $149.1 and $151.1, respectively, attributable to FGL’s non-life subsidiaries), which, if unused, will expire in tax years ending December 31, 2028 through 2037. At December 31, 2017 and September 30, 2017, HRG had approximately $423.1 and $315.9 of gross U.S. Federal capital loss carryforwards (inclusive of $15.0 and $15.0, respectively, attributable to FGL’s non-life subsidiaries), which, if unused, will expire in tax years December 31, 2019 through 2022. Approximately $387.9 of HRG’s gross U.S. Federal NOL is subject to limitations under Sections 382 of the Internal Revenue Code. The majority of HRG’s NOL and capital loss carryforwards have historically been subject to valuation allowances, as HRG concluded that all or a portion of the related tax benefits are not more-likely-than-not to be realized. On December 22, 2017, the Tax Reform Act was signed into law. The legislation significantly changes U.S. tax law by, among other things, lowering corporate income tax rates, implementing a dividends received deduction for dividends from foreign subsidiaries and imposing a tax on deemed repatriated accumulated earnings of foreign subsidiaries. The Tax Reform Act reduces the U.S. corporate income tax rate from a maximum of 35.0% to a flat 21.0% rate, effective January 1, 2018. HRG is a calendar year taxpayer, therefore HRG will be using the flat 21.0% rate for the January 1 to September 30, 2018 tax period and 35.0% for the October 1 to December 31, 2017 tax period. However, Spectrum Brands files its U.S. tax returns on a September fiscal year basis, its U.S. tax rate for Fiscal 2018 will be a blended rate of 24.53%. In response to the enactment of the Tax Reform Act, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Act. SAB 118 allows registrants to record provisional amounts during a one year measurement period in a manner similar to accounting for business combinations. The Company has followed the SAB 118 guidance. As a result of the new corporate tax rate, HRG is required to account for the effects of the change in tax law on its deferred tax balances as of the December 22, 2017 enactment date. HRG revalued its deferred tax balances applying the 21.0% tax rate based on the rate at which the deferred tax balances are expected to reverse in the future. As a result, HRG recognized a $287.2 reduction of tax benefits attributable to its net deferred tax assets. The reduction in tax benefits was fully offset by a reduction in the deferred tax asset valuation allowance. Accordingly, the revaluation of deferred at 21.0% has no impact on the accompanying Condensed Consolidated Statements of Operations for HRG, excluding Spectrum Brands, for the three months ended December 31, 2017. HRG’s valuation allowance at December 31, 2017 and September 30, 2017 totaled $430.8 and $703.2, respectively, (inclusive of $34.4 and $58.1, respectively, attributable to FGL’s non-life subsidiaries). The decrease in HRG’s valuation allowance was primarily due to the reduction of HRG’s deferred tax assets and liabilities as a result of the change in U.S. Federal tax rate, which is discussed further above. Spectrum Brands Spectrum Brands revalued its ending net deferred tax liabilities at December 31, 2017 and recognized a provisional $206.7 tax benefit in its income from continuing operations for the three months ended December 31, 2017. Spectrum Brands determined the impact of the U.S. federal corporate income tax rate change on the U.S. deferred tax assets and liabilities is provisional because certain of the timing differences reversing at Spectrum Brands’ Fiscal 2018 blended rate must be estimated until the Fiscal 2018 reversing timing differences are known. Spectrum Brands recognized the provisional tax impacts related to deemed repatriated earnings of $78.8 and the revaluation of deferred tax assets and liabilities mentioned above and included these amounts in the Condensed Consolidated Financial Statements for the three months ended December 31, 2017. The ultimate impact may differ from these provisional amounts, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions Spectrum Brands has made, additional regulatory guidance that may be issued, and actions Spectrum Brands may take as a result of the Tax Reform Act. The accounting is expected to be complete when the Fiscal 2018 U.S. corporate income tax return is filed in 2019. As of December 31, 2017, Spectrum Brands recorded $41.4 of valuation allowance against its U.S. state NOLs. It is currently unclear which of the Tax Reform Act provisions will be adopted by U.S. states. State conformity to the provisions of the Tax Reform Act could have a material impact on the valuation allowance recorded on U.S. state NOLs. The Tax Reform Act provided for a one-time deemed mandatory repatriation of post-1986 undistributed foreign subsidiary earnings and profits (“E&P”). Spectrum Brands had an estimated $623.1 of undistributed foreign E&P subject to the deemed mandatory repatriation and recognized a provisional $78.8 of income tax expense in its net income from continuing operations for the three months ended December 31, 2017. The mandatory repatriation tax is payable over eight years. The repatriation tax liability is classified as “Other long-term liabilities” in the accompanying Condensed Consolidated Balance Sheets as of December 31, 2017. The provisional tax expense for the mandatory repatriation is based on currently available information and additional information needs to be prepared, obtained and analyzed in order to determine the final amount, including further analysis of certain foreign exchange gains or losses, earnings and profits, foreign tax credits, and estimated cash and cash equivalents as of the measurement dates in the Tax Reform Act. Tax effects for changes to these items will be recorded in a subsequent quarter, as discrete adjustments to Spectrum Brands’ income tax provision, once complete. The Tax Reform Act provides for additional limitations on the deduction of business interest expense, effective with Spectrum Brands’ Fiscal 2019 tax year. Unused interest deductions can be carried forward and may be used in future years to the extent the interest limitation is not exceeded in those periods. It is possible that a portion of Spectrum Brands’ future U.S. interest expense could be nondeductible and impact Spectrum Brands’ effective tax rate. The Tax Reform Act also contains additional limits on deducting compensation, including performance-based compensation, in excess of $1.0 paid to certain executive officers for any fiscal year, effective with Spectrum Brands’ Fiscal 2019 tax year. Spectrum Brands’ future compensation payments will be subject to these limits, which could impact Spectrum Brands’ effective tax rate. Spectrum Brands continues to review the anticipated impacts of the global intangible low taxed income (“GILTI”) and base erosion anti-abuse tax (“BEAT”) on Spectrum Brands, which are not effective until fiscal year 2019. Spectrum Brands has not recorded any impact associated with either GILTI or BEAT in the tax rate for the three months ended December 31, 2018. The FASB allows an accounting policy election of either recognizing deferred taxes for temporary differences expected to reverse as GILTI in future years or treating such taxes as a current-period expense when incurred. Due to the complexity of calculating GILTI under the new law, Spectrum Brands has not determined which method they will apply. Spectrum Brands has recognized the provisional tax impacts related to deemed repatriated earnings and the revaluation of deferred tax assets and liabilities and included these amounts in the Condensed Consolidated Financial Statements for the three months ended December 31, 2017. The ultimate impact may differ from these provisional amounts, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions Spectrum Brands has made, additional regulatory guidance that may be issued, and actions Spectrum Brands may take as a result of the Tax Reform Act.

Commitments and Contingencies	Legal and Environmental Matters The Company and its subsidiaries are involved in litigation and claims arising out of their prior businesses and arising in the ordinary course out of their current businesses, which include, among other things, indemnification and other claims and litigations involving HRG’s and its subsidiaries’ business practices, transactions, workers compensation matters, environmental matters, and personal injury claims. However, based on currently available information, including legal defenses available to the Company, and given the Company’s existing accruals and related insurance coverage, the Company does not believe that the outcome of these legal, environmental and regulatory matters will have a material effect on its financial position, results of operations or cash flows. HRG HRG is a defendant in various litigation matters, including litigation arising out of its legacy and/or disposed of businesses. HRG does not believe that any of the matters or proceedings presently pending will have a material adverse effect on its results of operations, financial condition, liquidity or cash flows. See discussion above under the heading “Legal and Environmental Matters”. Spectrum Brands Spectrum Brands is a defendant in various litigation matters generally arising out of the ordinary course of business. Spectrum Brands does not believe that any of the matters or proceedings presently pending will have a material adverse effect on its results of operations, financial condition, liquidity or cash flows. Environmental. Spectrum Brands has provided for the estimated costs of $4.3 and $4.4 as of December 31, 2017 and September 30, 2017, respectively, associated with environmental remediation activities at some of its current and former manufacturing sites. Spectrum Brands believes that any additional liability in excess of the amounts provided that may result from resolution of these matters, will not have a material adverse effect on the financial condition, results of operations or cash flows of Spectrum Brands. Product Liability. Spectrum Brands may be named as a defendant in lawsuits involving product liability claims. Spectrum Brands has recorded and maintains an estimated liability in the amount of management’s estimate for aggregate exposure for such liabilities based upon probable loss from loss reports, individual cases, and losses incurred but not reported. As of December 31, 2017 and September 30, 2017, Spectrum Brands recognized $4.0 and $5.3 in product liability accruals, respectively, included in “Other current liabilities” in the accompanying Condensed Consolidated Balance Sheets. Spectrum Brands believes that any additional liability in excess of the amounts provided that may result from resolution of these matters, will not have a material adverse effect on the consolidated financial condition, results of operations or cash flows of Spectrum Brands. Product Warranty. Spectrum Brands recognizes an estimated liability for standard warranty on certain products when revenue on the sale of the warranted products is recognized. Estimated warranty costs incorporate replacement parts, products and delivery, and are recorded as a cost of goods sold at the time of product shipment based on historical and projected warranty claim rates, claims experience and any additional anticipated future costs on previously sold products. Spectrum Brands recognized $5.7 and $5.4 of warranty accruals as of December 31, 2017 and September 30, 2017, respectively, included in “Other current liabilities” in the accompanying Condensed Consolidated Balance Sheets. Product Safety Recall. On June 10, 2017, Spectrum Brands initiated a voluntary safety recall of various rawhide chew products for dogs sold by Spectrum Brands due to possible chemical contamination. As a result, Spectrum Brands recognized a loss related to the recall of $7.3 for the three months ended December 31, 2017, which comprised of inventory write-offs of $1.6 for inventory at our distribution centers and production facilities that were considered obsolete and disposed, customer losses of $0.4 for returned or disposed product held by our customers, and $5.3 of incremental costs for disposal and operating costs during a temporary shutdown and subsequent start up of production facilities impacted by the recall. Spectrum Brands suspended production at facilities impacted by the product safety recall, completed a comprehensive manufacturing review and subsequently recommenced production during the fiscal year ended September 30, 2017. The impacted production facilities are subject to incremental costs during start-up requiring alternative treatment on affected product SKUs until appropriate regulatory approvals have been received. The amounts for customer losses reflect the cost of the affected products returned to or replaced by Spectrum Brands and the expected cost to reimburse customers for costs incurred by them related to the recall. The incremental costs incurred directly by Spectrum Brands do not include lost earnings associated with interruption of production at Spectrum Brands’ facilities, or the costs to put into place corrective and preventative actions at those facilities. Spectrum Brands’ estimates for losses related to the recall are provisional and were determined based on an assessment of information currently available and may be revised in subsequent periods as Spectrum Brands continues to work with its customers to substantiate claims received to date and any additional claims that may be received. There have been no lawsuits or claims filed against Spectrum Brands related to the recalled product.

Consolidating Financial Information [Abstract]

Consolidating Financial Information

The following schedules present the Company’s accompanying Condensed Consolidated Balance Sheets information at December 31, 2017 and September 30, 2017, and accompanying Condensed Consolidated Statements of Operations information for the three months ended December 31, 2017 and 2016. These schedules present the individual segments of the Company and their contribution to the Condensed Consolidated Financial Statements. Amounts presented will not necessarily be the same as those in the individual financial statements of the Company’s subsidiaries due to adjustments for purchase accounting, income taxes and noncontrolling interests.

The Corporate and Other and eliminations column primarily reflects the parent company’s investment in its subsidiaries, invested cash portfolio and corporate debt, and the results of Salus and HGI Energy. Reflected in Corporate and Other is also $67.6 of negative book value of HGI Asset Management Holdings LLC as of December 31, 2017, which is primarily attributable to historical loan losses incurred by Salus. The elimination adjustments are for intercompany assets and liabilities, adjustments to align segment accounting policies with the consolidated basis, interest and dividends, the parent company’s investment in capital stocks of subsidiaries, and various reclasses of debit or credit balances to the amounts in consolidation. Purchase accounting adjustments have been pushed down to the appropriate subsidiary.

Significant Accounting Policies and Practices and Recent Accounting Pronouncements (Policies)	3 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Discontinued Operations, Policy [Policy Text Block]	Assets Held for Sale and Discontinued Operations A business classified as held for sale is recorded at the lower of its carrying amount or estimated fair value less cost to sell. If the carrying amount of the business exceeds its estimated fair value less cost to sell, a loss is recognized. Assets and liabilities related to a business classified as held for sale are segregated in the current and prior balance sheets in the period in which the business is classified as held for sale. Transactions between the business held for sale and businesses held for use that are expected to continue to exist after the disposal are not eliminated to appropriately reflect the continuing operations and balances held for sale. If a business is classified as held for sale after the balance sheet date but before the financial statements are issued or are available to be issued, the business continues to be classified as held and used in those financial statements when issued or when available to be issued. The Company reports the results of operations of a business as discontinued operations if a disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results when the business is sold or classified as held for sale, in accordance with ASC 360 and Accounting Standards Update (“ASU”) No. 2014-08, Presentation of Financial Statements (Topic 2015) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (“ASU 2014-08”). The results of discontinued operations are reported in “Income from discontinued operations, net of tax” in the accompanying Condensed Consolidated Statements of Operations for current and prior periods commencing in the period in which the business meets the criteria of a discontinued operation, and include any gain or loss recognized on closing or adjustment of the carrying amount to fair value less cost to sell. Transactions between the businesses held for sale and businesses held for use that are expected to continue to exist after the disposal are not eliminated to appropriately reflect the continuing operations and balances held for sale.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates and Assumptions The preparation of the Company’s Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and assumptions used.
Change in Accounting Method	Recent Accounting Pronouncements Not Yet Adopted The Company has implemented all new accounting pronouncements that are in effect and that may impact its Condensed Consolidated Financial Statements and does not believe that there are any other new accounting pronouncements, other than the ones disclosed in the Company’s Form 10-K, that have been issued that might have a material impact on its financial condition, results of operations or liquidity.

- Definition

The entire disclosure of changes in accounting principles, including adoption of new accounting pronouncements, that describes the new methods, amount and effects on financial statement line items.
