Schedule of Significant Accounting Policies [Line Items] |
Reclassifications [Policy Text Block] | Reclassifications Certain reclassifications from the prior year presentation have been made to conform to the current year presentation.
Principals of consolidation [Policy Text Block] | Principles of Consolidation As of June 30, 2016, our condensed consolidated financial statements include the accounts of (i) Icahn Enterprises and Icahn Enterprises Holdings and (ii) the wholly and majority owned subsidiaries of Icahn Enterprises and Icahn Enterprises Holdings, in addition to variable interest entities ("VIEs") in which we are the primary beneficiary. In evaluating whether we have a controlling financial interest in entities that we consolidate, we consider the following: (1) for voting interest entities, including limited partnerships and similar entities that are not VIEs, we consolidate these entities in which we own a majority of the voting interests; and (2) for VIEs, we consolidate these entities in which we are the primary beneficiary. See below for a discussion of our VIEs. Kick-out rights (which are the rights underlying the limited partners' ability to dissolve the limited partnership or otherwise remove the general partners and which are collectively referred to as "kick-out" rights) held through voting interests of partnerships and similar entities that are not VIEs are considered the equivalent of the equity interests of corporations that are not VIEs. All material intercompany accounts and transactions have been eliminated in consolidation. Except for our Investment segment, for those investments in which we own 50% or less but greater than 20%, we generally account for such investments using the equity method, while investments in affiliates of 20% or less are accounted for under the cost method.
Fair value of financial instruments [Policy Text Block] | Fair Value of Financial Instruments The carrying values of cash and cash equivalents, cash held at consolidated affiliated partnerships and restricted cash, accounts receivable, due from brokers, accounts payable, accrued expenses and other liabilities and due to brokers are deemed to be reasonable estimates of their fair values because of their short-term nature. See Note 4, “Investments and Related Matters,” and Note 5, “Fair Value Measurements,” for a detailed discussion of our investments. The fair value of our long-term debt is based on the quoted market prices for the same or similar issues or on the current rates offered to us for debt of the same remaining maturit ies. The carrying value and estimated fair value of our long-term debt as of June 30, 2016 was approximately $13.0 billion and $12.6 billion, respectively. The carrying value and estimated fair value of our long-term debt as of December 31, 2015 was approximately $12.6 billion and $12.2 billion, respectively.
Restricted cash [Policy Text Block] | Restricted Cash Our restricted cash balance was $507 million and $966 million as of June 30, 2016 and December 31, 2015, respectively.
Adoption of new accounting pronouncements [Policy Text Block] | Adoption of New Accounting Standards In February 2015, the FASB issued ASU No. 2015-02, which amends FASB ASC Topic 810, Consolidations. This ASU amends the current consolidation guidance, including introducing a separate consolidation analysis specific to limited partnerships and other similar entities. This ASU requires that limited partnerships and similar legal entities provide partners with either substantive kick-out rights or substantive participating rights over the general partner in order to be considered a voting interest entity. The specialized consolidation model and guidance for limited partnerships and similar legal entities have been eliminated. There is no longer a presumption that a general partner should consolidate a limited partnership. For limited partnerships and similar legal entities that qualify as voting interest entities, a limited partner with a controlling financial interest should consolidate a limited partnership. A controlling financial interest may be achieved through holding a limited partner interest that provides substantive kick-out rights. The standard is effective for annual periods beginning after December 15, 2015. As a result of adopting this guidance in the first quarter of 2016, while certain of our limited partnership entities are now considered VIEs, we continue to consolidate these limited partnerships. See above for further discussion regarding our VIEs. In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, which amends FASB ASC Subtopic 835-30, Interest - Imputation of Interest. The new standard requires that all costs incurred to issue debt be presented in the balance sheet as a direct deduction from the carrying value of the debt. Given the absence of authoritative guidance within this ASU regarding debt issuance costs related to line-of-credit, the SEC staff has stated that it would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred issuance costs ratably over the term of the line-of-credit arrangement. The standard is effective for interim and annual periods beginning after December 15, 2015 and is required to be applied on a retrospective basis. Early adoption is permitted. The adoption of this guidance resulted in a reclassification of debt issuance costs on our condensed consolidated balance sheets to debt in the amount of $39 million as of December 31, 2015. In September 2015, the FASB issued ASU No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments, which amends FASB ASC Topic 805, Business Combinations. This ASU eliminates the requirement to retrospectively adjust provisional amounts recognized at the acquisition dates of business combinations. Rather, this ASU requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. This ASU is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. The amendments in this ASU should be applied prospectively to adjustments to provisional amounts that occur after the effective date with earlier application permitted for financial statements that have not been issued. The adoption of this guidance in the first quarter of 2016 did not have a material impact on our condensed consolidated financial position, results of operations, comprehensive income, cash flows and disclosures.
Recently issued accounting pronouncements [Policy Text Block] | Recently Issued Accounting Standards In May 2014, the FASB issued ASU No. 2014-09, creating a new topic, FASB ASC Topic 606, Revenue from Contracts with Customers, superseding revenue recognition requirements in FASB ASC Topic 605, Revenue Recognition. This ASU requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. In addition, an entity is required to disclose sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. This ASU was amended by ASU No. 2015-14, issued in August 2015, which deferred the original effective date by one year; the effective date of this ASU is for fiscal years, and interim reporting periods within those years, beginning after December 15, 2017, using one of two retrospective application methods. In addition, the FASB issued other amendments during 2016 to FASB ASC Topic 606, Revenue from Contracts with Customers, that include implementation guidance to principal versus agent considerations, guidance to identifying performance obligations and licensing guidance and other narrow scope improvements. Early adoption is permitted only as of the annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. We are currently evaluating the impact of these guidance on our consolidated financial position, results of operations, comprehensive income, cash flows and disclosures. In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory, which amends FASB ASC Topic 330, Inventory. This ASU requires entities to measure inventory at the lower of cost or net realizable value and eliminates the option that currently exists for measuring inventory at market value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. This ASU should be applied prospectively with earlier application permitted as of the beginning of an interim period or annual reporting period. We anticipate that the adoption of this guidance will have minimal impact on our consolidated financial position, results of operations, comprehensive income, cash flows and disclosures. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall, which amends FASB ASC Topic 825, Financial Instruments. This ASU requires that equity investments (except those accounted for under the equity method of accounting or those that result in the consolidation of the investee) to be measured at fair value with changes recognized in earnings. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment. In addition, there were other amendments to certain disclosure and presentation matters pertaining to financial instruments, including the requirement of an entity to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The amendments in this ASU should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values should be applied prospectively to equity investments that exist as of the date of adoption. Early application is permitted for certain matters only. We are currently evaluating the impact of this guidance on our consolidated financial position, results of operations, comprehensive income, cash flows and disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which supersedes FASB ASC Topic 840, Leases. This ASU requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. In addition, among other changes to the accounting for leases, this ASU retains the distinction between finance leases and operating leases. The classification criteria for distinguishing between finance leases and operating leases are substantially similar to the classification criteria for distinguishing between capital leases and operating leases in the previous guidance. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The amendments in this ASU should be applied using a modified retrospective approach. Early application is permitted. We are currently evaluating the impact of this guidance on our consolidated financial position, results of operations, comprehensive income, cash flows and disclosures. In March 2016, the FASB issued ASU No. 2016-07, Simplifying the transition to equity method of accounting, which amends FASB ASC Topic 323, Investments - Equity Method and Joint Ventures. This ASU eliminates the retroactive adjustment of an investment that qualifies for the equity method as a result of an increase in the level of ownership or degree of influence as if the equity method had been in effect during all previous periods that the investment had been held. The amendments in this ASU are effective for interim and annual fiscal years beginning after December 15, 2016. Earlier application is permitted. We anticipate that the adoption of this guidance will have minimal impact on our consolidated financial position, results of operations, comprehensive income, cash flows and disclosures. In June 2016, the FASB issued ASU No. 2016-13, Measurement of credit losses on financial instruments, which amends FASB ASC Topic 326, Financial Instruments - Credit Losses. This ASU requires financial assets measured at amortized cost to be presented at the net amount to be collected and broadens the information, including forecasted information incorporating more timely information, that an entity must consider in developing its expected credit loss estimate for assets measured. We are currently evaluating the impact of this guidance on our consolidated financial position, results of operations, comprehensive income, cash flows and disclosures.
Variable Interest Entity Disclosure [Text Block] | Variable Interest Entities As further discussed below, the Financial Statement Accounting Standards Board's ("FASB") Accounting Standards Update ("ASU") No. 2015-02 became effective during the first quarter of 2016. ASU No. 2015-02 amends the current consolidation guidance, including introducing a separate consolidation analysis specific to limited partnerships and other similar entities. Specifically, under the revised consolidation analysis, limited partnerships and other similar entities are considered VIEs unless the limited partners hold substantive kick-out rights or participating rights. Although ASU No. 2015-02 changed the status of certain of our limited partnership entities as VIEs (as discussed below), we continue to consolidate these entities because we are the primary beneficiaries of such entities. Investment Our Investment segment is comprised of various private investment funds, including Icahn Partners L.P. ("Icahn Partners") and Icahn Partners Master Fund LP ("Master Fund") (collectively, the "Investment Funds"), through which we invest our proprietary capital. See Note 2, "Operating Unit - Investment," for further discussion regarding our Investment segment's business. We determined that each of the Investment Funds are considered VIEs because these limited partnerships lack both substantive kick-out and participating rights. Because we are the general partner in each of the Investment Funds and have significant limited partner interests in each of the Investment Funds, coupled with our significant exposure to losses and benefits in each of the Investment Funds, we are the primary beneficiary of each of the Investment Funds and therefore continue to consolidate each of the Investment Funds. Substantially all of the assets and liabilities of our Investment segment pertain to the Investment Funds. See Note 13, "Segment Reporting," for details of our condensed balance sheets for our Investment segment. Energy We conduct our Energy segment through our majority ownership in CVR Energy Inc. ("CVR"). CVR owns petroleum refining and nitrogen fertilizer manufacturing businesses held through CVR Refining, LP (“CVR Refining”) and CVR Partners, LP (“CVR Partners”), respectively, and each are considered VIEs. See Note 2, "Operating Unit - Energy," for further discussion regarding our Energy segment's business. Our Energy segment determined that CVR Refining and CVR Partners are each considered VIEs because each of these limited partnerships lack both substantive kick-out and participating rights. In addition, our Energy segment also concluded that based upon its general partner's roles and rights in CVR Refining and CVR Partners as afforded by their respective partnership agreements, coupled with its exposure to losses and benefits in each of CVR Refining and CVR Partners through its significant limited partner interests, intercompany credit facilities and services agreements, CVR determined that it is the primary beneficiary of both CVR Refining and CVR Partners. Based upon this evaluation, CVR continues to consolidate both CVR Refining and CVR Partners. The assets and liabilities of our Energy segment that are directly related to CVR Refining and CVR Partners included in our condensed consolidated balance sheets are as follows:
| June 30, 2016 |  | December 31, 2015
| (in millions)
Cash and cash equivalents | $ | 236 |  |  | $ | 237 |
Property, plant and equipment, net | 3,408 |  |  | 2,674 |
Inventories | 325 |  |  | 290 |
Goodwill | — |  |  | 574 |
Intangible assets, net | 328 |  |  | 337 |
Other assets | 94 |  |  | 102 |
Accounts payable, accrued expenses and other liabilities | 364 |  |  | 333 |
Debt | 1,167 |  |  | 667 |
Icahn Enterprises Holdings As discussed above, Icahn Enterprises Holdings and its subsidiaries own substantially all of our assets and liabilities and conduct substantially all of our operations. We determined that Icahn Enterprises Holdings is a VIE because it lacks both substantive kick-out and participating rights. Icahn Enterprises is the primary beneficiary of Icahn Enterprises Holdings principally based on its 99% limited partner interest in Icahn Enterprises Holdings and therefore continues to consolidate Icahn Enterprises Holdings. The condensed consolidated financial statements of Icahn Enterprises Holdings are included in this Report.
Automotive Segment [Member] |
Schedule of Significant Accounting Policies [Line Items] |
Inventory, Policy [Policy Text Block] | Inventories As further discussed in Note 2, "Operating Units - Automotive," we acquired Pep Boys - Manny, Moe and Jack ("Pep Boys") on February 3, 2016. Pep Boys' inventories are valued at lower of cost or market and cost of goods sold is determined using the last-in, first-out ("LIFO") method. Pep Boys is currently the only subsidiary of ours that uses LIFO in determining cost of goods sold. As inventories of Pep Boys have been revalued to fair value as a result of our acquisition on February 3, 2016, there are immaterial differences between inventory balances calculated using LIFO as compared to inventory balances calculated using first-in, first-out as of June 30, 2016.
