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.
