Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Basis of Presentation	Description of Business and Basis of Presentation . General Icahn Enterprises L.P. (“Icahn Enterprises”) is a master limited partnership formed in Delaware on February 17, 1987. Icahn Enterprises Holdings L.P. (“Icahn Enterprises Holdings”) is a limited partnership formed in Delaware on February 17, 1987. References to "we," "our" or "us" herein include both Icahn Enterprises and Icahn Enterprises Holdings and their subsidiaries, unless the context otherwise requires. Icahn Enterprises owns a 99% limited partner interest in Icahn Enterprises Holdings. Icahn Enterprises G.P. Inc. (“Icahn Enterprises GP”), which is owned and controlled by Mr. Carl C. Icahn, owns a 1% general partner interest in each of Icahn Enterprises and Icahn Enterprises Holdings as of March 31, 2016 . Icahn Enterprises Holdings and its subsidiaries own substantially all of our assets and liabilities and conduct substantially all of our operations. Therefore, the financial results of Icahn Enterprises and Icahn Enterprises Holdings are substantially the same, with differences relating primarily to debt, as discussed further in Note 10 , " Debt ," and to the allocation of the general partner interest, which is reflected as an aggregate 1.99% general partner interest in the financial statements of Icahn Enterprises. In addition to the above, Mr. Icahn and his affiliates owned approximately 89.1% of Icahn Enterprises' outstanding depositary units as of March 31, 2016 . We are a diversified holding company owning subsidiaries currently engaged in the following continuing operating businesses: Investment, Automotive, Energy, Metals, Railcar, Gaming, Mining, Food Packaging, Real Estate and Home Fashion. We also report the results of our Holding Company, which includes the results of certain subsidiaries of Icahn Enterprises and Icahn Enterprises Holdings (unless otherwise noted), and investment activity and expenses associated with the Holding Company. Further information regarding our reporting segments is contained in Note 2 , “ Operating Units ,” and Note 13 , “ Segment Reporting .” We conduct and plan to continue to conduct our activities in such a manner as not to be deemed an investment company under the Investment Company Act of 1940, as amended (the “'40 Act”). Therefore, no more than 40% of our total assets can be invested in investment securities, as such term is defined in the '40 Act. In addition, we do not invest or intend to invest in securities as our primary business. We intend to structure our investments to continue to be taxed as a partnership rather than as a corporation under the applicable publicly traded partnership rules of the Internal Revenue Code, as amended (the “Code”). The accompanying condensed consolidated financial statements and related notes should be read in conjunction with our consolidated financial statements and related notes contained in our Annual Report on Form 10-K for the year ended December 31, 2015. The condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) related to interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. The financial information contained herein is unaudited; however, management believes all adjustments have been made that are necessary to present fairly the results for the interim periods. All such adjustments are of a normal and recurring nature. Reclassifications Certain reclassifications from the prior year presentation have been made to conform to the current year presentation. Principles of Consolidation As of March 31, 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. 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: March 31, 2016 December 31, 2015 (in millions) Cash and cash equivalents $ 198 $ 237 Property, plant and equipment, net 2,667 2,674 Inventories 259 290 Goodwill — 574 Intangible assets, net 332 337 Other assets 78 102 Accounts payable, accrued expenses and other liabilities 335 333 Debt 668 667 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. 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 March 31, 2016 was approximately $12.5 billion and $12.1 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 Our restricted cash balance was $564 million and $966 million as of March 31, 2016 and December 31, 2015 , respectively. 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 March 31, 2016 . 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 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. 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 this 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 March 2016, the FASB issued ASU No. 2016-08, Principal versus agent considerations (reporting revenue gross versus net), which amends FASB ASC Topic 606, Revenue from Contracts with Customers. This ASU clarifies the implementation guidance on principal versus agent considerations, including providing guidance on indicators to assist in the evaluation as to whether an entity controls a specified good or service before it is transferred to the customers. The amendments in this ASU is effective the same time that FASB ASU No. 2014-09 becomes effective. We are currently evaluating the impact of this guidance on our consolidated financial position, results of operations, comprehensive income, cash flows and disclosures.

Operating Units [Abstract]
Operating Units	Operating Units . Investment Our Investment segment is comprised of various private investment funds, including the Investment Funds, through which we invest our proprietary capital. We and certain of Mr. Icahn's wholly owned affiliates are the sole investors in the Investment Funds. Icahn Onshore LP and Icahn Offshore LP (together, the "General Partners") act as the general partner of Icahn Partners and the Master Fund, respectively. The General Partners provide investment advisory and certain administrative and back office services to the Investment Funds but do not provide such services to any other entities, individuals or accounts. Interests in the Investment Funds are not offered to outside investors. We had interests in the Investment Funds with a fair value of approximately $1.8 billion and $3.4 billion as of March 31, 2016 and December 31, 2015, respectively. Automotive We conduct our Automotive segment through our majority ownership in Federal-Mogul Holdings Corporation ("Federal-Mogul"), our wholly owned subsidiary IEH Auto Parts Holding LLC ("IEH Auto"), effective June 1, 2015, and our wholly owned subsidiary Pep Boys, effective February 3, 2016 (see acquisition below). Federal-Mogul is a leading global supplier of a broad range of components, accessories and systems to the automotive, small engine, heavy-duty, marine, railroad, agricultural, off-road, aerospace and energy, industrial and transport markets, including customers in both the original equipment manufacturers and servicers (“OE”) market and the replacement market (“aftermarket”). Federal-Mogul’s customers include the world’s largest automotive OEs and major distributors and retailers in the independent aftermarket. Federal-Mogul operates with two end-customer focused businesses. The Powertrain business unit focuses on original equipment products for automotive, heavy duty and industrial applications. The Motorparts business unit sells and distributes a broad portfolio of products in the global aftermarket, while also serving original equipment manufacturers with products including braking, chassis, wipers and other vehicle components. As of March 31, 2016 , we owned approximately 82.0% of the total outstanding common stock of Federal-Mogul. On February 28, 2016, Icahn Enterprises issued a proposal to the board of directors of Federal-Mogul to purchase the remaining shares of Federal-Mogul common stock not owned by us in a merger transaction pursuant to which Federal-Mogul shareholders would receive $7.00 per share in cash for their shares of Federal-Mogul common stock. Federal-Mogul’s board of directors subsequently authorized the formation of a special committee consisting of three of the four independent members of Federal-Mogul's board of directors to review and evaluate this proposal and any alternative transactions involving Federal-Mogul. Following its formation, the special committee engaged Houlihan Lokey Capital, Inc. as its financial advisor and Richards, Layton & Finger as its legal counsel. The special committee, working with its advisors, has commenced its review and evaluation of Icahn Enterprises' proposal and alternatives thereto. Subsequent to submitting its proposal, Icahn Enterprises advised Federal-Mogul's board of directors that it was not considering selling its stake in Federal-Mogul at the current time. Pep Boys has 805 locations in the automotive aftermarket industry located throughout the United States and Puerto Rico. Pep Boys stores are organized into a hub and spoke network consisting of Supercenters and Service & Tire Centers. Supercenters average approximately 20,000 square feet and combine a parts and accessories store with professional service centers that perform a full range of automotive maintenance and repair services. Most of the Pep Boys Supercenters also have a commercial sales program that provides prompt delivery of parts, tires and equipment to automotive repair shops and dealers. Service & Tire Centers, which average approximately 6,000 square feet, provide automotive maintenance and repair services in neighborhood locations that are conveniently located where our customers live or work. IEH Auto has 32 distribution centers and satellite locations and 274 corporate-owned jobber stores in the United States and supports a network of more than 2,000 independent wholesalers. Through its banner and technical support programs as well as its offering of premium auto parts, IEH Auto has built its reputation on being the partner of choice for independent entrepreneurs eager to tap into the strength of large network. Pep Boys and IEH Auto are being operated together in order to grow their sales to do-it-for-me ("DIFM") distributors and DIFM service professionals, to grow their automotive service business, and to maintain their do-it-yourself customer bases by offering the newest and broadest product assortment in the automotive aftermarket. In addition, Federal-Mogul is operated independently from Pep Boys and IEH Auto. Transactions among Federal-Mogul, Pep Boys and IEH Auto have been eliminated in consolidation. Pep Boys Acquisition On February 3, 2016, pursuant to a tender offer, Icahn Enterprises acquired a majority of the outstanding shares of Pep Boys. On February 4, 2016, Icahn Enterprises completed the acquisition of the remaining outstanding shares of Pep Boys and our wholly owned subsidiary, IEP Parts Acquisition LLC, merged with and into Pep Boys, with Pep Boys surviving the merger as a wholly owned subsidiary of Icahn Enterprises Holdings. The total value for the acquisition of Pep Boys was approximately $1.2 billion , including the fair value of our equity interest in Pep Boys just prior to our acquisition of a controlling interest. Prior to obtaining a controlling interest, we remeasured our equity interest in Pep Boys to its acquisition-date fair value of $121 million . The difference between the carrying value and the acquisition-date fair value of our equity interest in Pep Boys was immaterial. A preliminary valuation of the net assets of the Pep Boys acquisition resulted in $943 million allocated to tangible net assets and $293 million allocated to goodwill and other intangible net assets as of the acquisition date. Our allocation to other intangible net assets includes $69 million allocated to unfavorable leases liability which is included in accrued expenses and other liabilities on the condensed consolidated balance sheets. We are in the process of valuing the Pep Boys acquisition and have recorded provisional amounts based on preliminary estimates of fair value of net assets acquired, including goodwill. The provisional measurements of net assets are subject to change as we finalize the purchase price allocation. The acquisition of Pep Boys was not material, individually or in the aggregate with the Trump (as defined below) business acquisition, to our condensed consolidated financial statements. Accounts Receivable, net Federal-Mogul's subsidiaries in Brazil, France, Germany, Italy and the United States are party to accounts receivable factoring and securitization facilities. Gross accounts receivable transferred under these facilities were $491 million and $408 million as of March 31, 2016 and December 31, 2015, respectively. Of those gross amounts, $479 million and $401 million , respectively, qualify as sales as defined in FASB ASC Topic 860, Transfers and Servicing . The remaining transferred receivables were pledged as collateral and accounted for as secured borrowings and recorded in the condensed consolidated balance sheets within accounts receivable, net and debt. Under the terms of these facilities, Federal-Mogul is not obligated to draw cash immediately upon the transfer of accounts receivable. As of March 31, 2016 and December 31, 2015, Federal-Mogul had withdrawn cash related to such transferred receivables of $1 million and $1 million , respectively. Proceeds from the transfers of accounts receivable qualifying as sales were $413 million and $390 million for the three months ended March 31, 2016 and 2015, respectively. For the three months ended March 31, 2016 and 2015, expenses associated with transfers of receivables were $3 million and $2 million , respectively. Such expenses were recorded in the condensed consolidated statements of operations within other income (loss), net. Where Federal-Mogul receives a fee to service and monitor these transferred receivables, such fees are sufficient to offset the costs and as such, a servicing asset or liability is not incurred as a result of such activities. Certain of the facilities contain terms that require Federal-Mogul to share in the credit risk of the sold receivables. The maximum exposure to Federal-Mogul associated with certain of these facilities' terms were $4 million and $11 million as of March 31, 2016 and December 31, 2015, respectively. Restructuring During the three months ended March 31, 2016 and 2015, Federal-Mogul recorded $15 million and $12 million , respectively, in restructuring charges. These restructuring charges, primarily consisting of employee costs and headcount reductions, pertain to all restructuring programs that Federal-Mogul has initiated in order to improve its operating performance. Federal-Mogul's restructuring expenses for the three months ended March 31, 2016 are aimed at optimizing its cost structure. Federal-Mogul expects to complete these programs in 2017 and incur additional restructuring and other charges of approximately $1 million . For programs previously initiated in prior periods, Federal-Mogul expects to complete these programs in 2018 and incur additional restructuring charges of approximately $5 million . Energy We conduct our Energy segment through our majority ownership in CVR. CVR is a diversified holding company primarily engaged in the petroleum refining and nitrogen fertilizer manufacturing industries through its holdings in CVR Refining and CVR Partners, respectively. CVR Refining is an independent petroleum refiner and marketer of high value transportation fuels. CVR Partners produces and markets nitrogen fertilizers in the form of urea ammonium nitrate ("UAN") and ammonia. As of March 31, 2016 , CVR owned 100% of the general partners of CVR Refining and CVR Partners and approximately 66% of the common units of CVR Refining and approximately 53% of the common units of CVR Partners. Immediately subsequent to the completion of the mergers, as discussed below, CVR held approximately 34% of the outstanding common units of CVR Partners and 100% of the general partner interest. As of March 31, 2016 , we owned approximately 82.0% of the total outstanding common stock of CVR. In addition, as of March 31, 2016 , we owned approximately 4.0% of the total outstanding common units of CVR Refining directly. CVR Partners - Rentech Mergers On April 1, 2016, CVR Partners completed its merger with Rentech Nitrogen Partners, L.P., now known as East Dubuque Nitrogen, L.P. ("East Dubuque"), a publicly traded partnership whose common units were formerly listed on the New York Stock Exchange under the ticker symbol "RNF", and Rentech Nitrogen GP, LLC, now known as East Dubuque Nitrogen GP, LLC ("East Dubuque GP"), pursuant to which CVR Partners acquired East Dubuque and East Dubuque GP. In connection with the merger, CVR Partners issued approximately 40.2 million common units to East Dubuque common unitholders and paid $99 million in cash consideration. East Dubuque’s debt arrangements that remained in place until the closing date of the mergers included $320 million of Second Lien Notes due 2021 ("Second Lien Notes"). East Dubuque is required under the change of control provision within the indenture governing the Second Lien Notes to offer to purchase, within 90 days of the mergers, all outstanding Second Lien Notes at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest thereon to the date of purchase. On April 1, 2016, in connection with the closing of the mergers, CVR Partners entered into a new $320 million senior term loan facility with AEPC, a wholly owned subsidiary of Icahn Enterprises, as the lender, which (i) may be used by CVR to provide funds to East Dubuque to make a change of control offer and, and if applicable, a "clean-up" redemption in accordance with the indenture governing the Second Lien Notes or (ii) may be used by CVR Partners or East Dubuque to make a tender offer for the Second Lien Notes and, in each case, pay fees and expenses thereto. East Dubuque, located in East Dubuque, Illinois, owns and operates two fertilizer facilities, producing primarily ammonia and UAN using natural gas as its facility's primary feedstock. The primary reasons for the mergers were to expand CVR Partners geographical footprint, diversify its raw material feedstocks, widen its customer reach and increase its potential cash-flow generation. Petroleum Business CVR Refining's petroleum business includes a 115,000 barrels per calendar day ("bpcd") rated capacity complex full coking medium-sour crude oil refinery in Coffeyville, Kansas and a 70,000 bpcd rated capacity complex crude oil refinery in Wynnewood, Oklahoma. The Coffeyville refinery is situated on approximately 440 acres in southeast Kansas, approximately 100 miles from Cushing, Oklahoma, a major crude oil trading and storage hub. The Wynnewood refinery is situated on approximately 400 acres located approximately 65 miles south of Oklahoma City, Oklahoma and approximately 130 miles from Cushing, Oklahoma. In addition to the refineries, CVR's petroleum business owns and operates the following: (i) a crude oil gathering system with a gathering capacity of over 65,000 barrels per day ("bpd") serving Kansas, Oklahoma, Missouri, Nebraska, Colorado and Texas; (ii) a 170,000 bpd pipeline system (supported by approximately 336 miles of active owned and leased pipeline) that transports crude oil to its Coffeyville refinery from its Broome Station facility near Caney, Kansas; (iii) approximately 6.4 million barrels of company owned and leased crude oil storage capacity; (iv) a rack marketing division supplying product through tanker trucks directly to customers located in close geographic proximity to Coffeyville, Kansas and Wynnewood, Oklahoma and at throughput terminals on Magellan and NuStar Energy, LP's ("NuStar") refined products distribution systems; and (v) over 4.5 million barrels of combined refinery related storage capacity. Nitrogen Fertilizer Business CVR Partners' nitrogen fertilizer business consists of a nitrogen fertilizer manufacturing facility that utilizes a petroleum coke, or pet coke, gasification process to produce nitrogen fertilizer. The facility includes a 1,300 ton-per-day ammonia unit, a 3,000 ton-per-day UAN unit and a gasifier complex having a capacity of 89 million standard cubic feet per day of hydrogen. The gasifier is a dual-train facility, with each gasifier able to function independently of the other, thereby providing redundancy and improving reliability. Metals We conduct our Metals segment through our indirect wholly owned subsidiary, PSC Metals, Inc. (“PSC Metals”). PSC Metals collects industrial and obsolete scrap metal, processes it into reusable forms and supplies the recycled metals to its customers, including electric-arc furnace mills, integrated steel mills, foundries, secondary smelters and metals brokers. PSC Metals’ ferrous products include busheling, plate and structural, shredded, sheared and bundled scrap metal and other purchased scrap metal such as turnings (steel machining fragments), cast furnace iron and broken furnace iron. PSC Metals processes the scrap into a size, density and purity required by customers to meet their production needs. PSC Metals also processes non-ferrous metals, including aluminum, copper, brass, stainless steel and nickel-bearing metals. Non-ferrous products are a significant raw material in the production of aluminum and copper alloys used in manufacturing. PSC Metals also operates a steel products business that includes the supply of secondary plate and structural grade pipe that is sold into niche markets for counterweights, piling and foundations, construction materials and infrastructure end-markets. PSC Metals also purchases end of life vehicles, dismantles those vehicles, resells valuable parts, and ships the resulting vehicle hulks to our shredder yards. Railcar We conduct our Railcar segment through our majority ownership interest in ARI and our wholly owned subsidiary American Railcar Leasing, LLC ("ARL"). ARI manufactures railcars that are offered for sale or lease, custom and standard railcar components and other industrial products, primarily aluminum and special alloy steel castings. These products are sold to various types of companies including shippers, leasing companies, industrial companies, and Class I railroads. ARI leases railcars that it manufactures to certain markets that include the energy, food and agriculture, chemical, minerals and petrochemical industries. ARI provides railcar services consisting of railcar repair services, ranging from full to light repair, engineering and on-site repairs and maintenance through its various repair facilities, including mini repair shops and mobile repair units. ARL is engaged in the business of leasing railcars to customers with specific requirements whose products require specialized railcars dedicated to transporting, storing, and preserving the integrity of their products. These products are primarily in the energy, food and agriculture, chemical, minerals and petrochemical industries. Transactions between ARI and ARL have been eliminated in consolidation. As of March 31, 2016 , we owned approximately 60.7% of the total outstanding common stock of ARI. Gaming We conduct our Gaming segment through our majority ownership in Tropicana and our wholly owned subsidiary, Trump Entertainment Resorts, Inc. (“Trump”) which owns and operates Trump Taj Mahal Casino Resort. As discussed below, we obtained control and began consolidating the results of Trump upon its emergence from bankruptcy on February 26, 2016. Tropicana owns and operates a diversified, multi-jurisdictional collection of casino gaming properties. The eight casino facilities it operates feature approximately 392,000 square feet of gaming space with 7,900 slot machines, 270 table games and 5,500 hotel rooms with two casino facilities located in Nevada and one in each of Mississippi, Missouri, Indiana, Louisiana, New Jersey and Aruba. Trump owns and operates Trump Taj Mahal Casino Resort ("Trump Taj Mahal") which is located in Atlantic City, New Jersey. Trump Taj Mahal features approximately 160,000 square feet of gaming space with 2,500 slot machines, 130 table games and 2,000 hotel rooms. In addition, Trump also owns an idled casino property in Atlantic City, New Jersey, Trump Plaza Hotel and Casino, which ceased operations in September 2014. As of March 31, 2016 , we owned approximately 68.5% of the total outstanding common stock of Tropicana. Trump Acquisition On September 9, 2014, Trump and its subsidiaries filed voluntary Chapter 11 petitions in the United States Bankruptcy Court for the District of Delaware in Wilmington, Delaware. On February 26, 2016 (the "Effective Date"), Trump emerged from bankruptcy. Icahn Enterprises was the sole holder of Trump's senior secured debt. On the Effective Date, among other things, the existing pre-petition senior secured debt with a face amount of $286 million held by Icahn Enterprises was extinguished and converted into 100% of Trump’s New Common Stock (as defined in the bankruptcy plan). As a result, we became the 100% owner of Trump after reorganization and accordingly, obtained control and began consolidating the results of Trump on February 26, 2016. We accounted for this this acquisition as a business combination under FASB ASC Topic 805, Business Combinations . Prior to obtaining a controlling interest in Trump upon its emergence from bankruptcy, we remeasured our interest in Trump to its acquisition-date fair value of $126 million , resulting in a $16 million gain on investment activities. A preliminary valuation of the net assets of the Trump business resulted in $109 million allocated to tangible net assets and $17 million to trademarks and brand names. We are in the process of valuing the Trump acquisition and have recorded provisional amounts based on preliminary estimates of fair value of net assets acquired. The provisional measurements of net assets are subject to change as we finalize the purchase price allocation. Additionally, at the acquisition date, Trump had a full valuation allowance on its deferred tax assets. We are in the process of obtaining the information necessary for evaluating the valuation allowance and deferred tax assets acquired. It is possible that a portion of the valuation allowance on the Trump deferred tax assets will be adjusted in future periods. The acquisition of Trump was not material, individually or in the aggregate with the Pep Boys acquisition, to our condensed consolidated financial statements. Mining We conduct our Mining segment through our majority ownership in Ferrous Resources. We obtained control of and consolidated the results of Ferrous Resources during the second quarter of 2015. Ferrous Resources acquired certain rights to iron ore mineral resources in Brazil and develops mining operations and related infrastructure to produce and sell iron ore products to the global steel industry. Ferrous Resources has acquired significant iron ore assets in the State of Minas Gerais, Brazil, known as Viga, Viga Norte, Esperança, Serrinha and Santanense. In addition, Ferrous Resources has acquired certain mineral rights near Jacuípe in the State of Bahia, Brazil. Of the assets acquired, Viga, Esperança and Santanense are already extracting and producing iron ore, while the other assets are at an early stage of exploration. In response to the current depressed iron ore price environment, Ferrous Resources decided to temporarily suspend Esperança's and Santanense's operations during the first quarter of 2015 in order to study alternatives to further reduce cost of production and improve product quality and therefore to improve profitability and margin per metric ton. As of March 31, 2016 , we owned approximately 77.2% of the total outstanding common stock of Ferrous Resources. Food Packaging We conduct our Food Packaging segment through our majority ownership in Viskase Companies, Inc. ("Viskase"). Viskase is a worldwide leader in the production and sale of cellulosic, fibrous and plastic casings for the processed meat and poultry industry. Viskase currently operates nine manufacturing facilities, six distribution centers and three service centers throughout North America, Europe, South America and Asia and derives approximately 69% of its total net sales from customers located outside the United States for the three months ended March 31, 2016 . As of March 31, 2016 , we owned approximately 73.3% of the total outstanding common stock of Viskase. Real Estate Our Real Estate segment consists of rental real estate, property development and club activities. As of March 31, 2016 , we owned 15 commercial rental real estate properties. Our property development operations are run primarily through Bayswater Development LLC, a real estate investment, management and development subsidiary that focuses primarily on the construction and sale of single-family and multi-family homes, lots in subdivisions and planned communities and raw land for residential development. Our New Seabury development property in Cape Cod, Massachusetts and our Grand Harbor development property in Vero Beach, Florida include land for future residential development of approximately 239 and 1,128 units of residential housing, respectively. Both our developments operate golf and club operations as well. In addition, our Real Estate segment owns an unfinished development property which is located on approximately 23 acres in Las Vegas, Nevada. Home Fashion We conduct our Home Fashion segment through our indirect wholly owned subsidiary, WestPoint Home LLC (“WPH”), a manufacturer and distributor of home fashion consumer products. WPH is engaged in the business of designing, marketing, manufacturing, sourcing, distributing and selling home fashion consumer products. WPH markets a broad range of manufactured and sourced bed, bath, basic bedding, and other textile products, including sheets, pillowcases, bedspreads, quilts, comforters and duvet covers, bath and beach towels, bath accessories, bed skirts, bed pillows, flocked blankets, woven blankets and throws and mattress pads. WPH recognizes revenue primarily through the sale of home fashion products to a variety of retail and institutional customers. In addition, WPH receives a small portion of its revenues through the licensing of its trademarks.

As of March 31, 2016 and December 31, 2015, the total fair market value of investments in the Investment Funds made by Mr. Icahn and his affiliates (excluding Icahn Enterprises and Icahn Enterprises Holdings) was approximately $4.1 billion and $4.1 billion , respectively, representing approximately 69% and 55% , respectively, of the Investment Funds' assets under management. Icahn Capital LP ("Icahn Capital") pays for expenses pertaining to the operation, administration and investment activities of our Investment segment for the benefit of the Investment Funds (including salaries, benefits and rent). Effective April 1, 2011, based on an expense-sharing arrangement, certain expenses borne by Icahn Capital are reimbursed by the Investment Funds. For the three months ended March 31, 2016 and 2015, $(12) million and $98 million , respectively, was allocated to the Investment Funds based on this expense-sharing arrangement. The expense reversal for the three months ended March 31, 2016 was primarily due to a reversal of performance related compensation expense accrual. Railcar ARL Acquisition On February 29, 2016, Icahn Enterprises entered into a contribution agreement with IRL Holding, LLC ("IRL"), an affiliate of Mr. Icahn, to acquire the remaining 25% economic interest in ARL not already owned by us. Pursuant to this contribution agreement, we contributed 685,367 newly issued depositary units of Icahn Enterprises to IRL in exchange for the remaining 25% economic interest in ARL. As a result of the transaction, we own a 100.0% economic interest in ARL. This transaction was authorized by the independent committee of the board of directors of the general partner of Icahn Enterprises. The independent committee was advised by independent counsel and retained an independent financial advisor which rendered a fairness opinion. Agreements with ACF Industries LLC ARI has from time to time purchased components from ACF Industries LLC ("ACF"), an affiliate of Mr. Icahn, under a long-term agreement, as well as on a purchase order basis. ACF is a manufacturer and fabricator of specialty railcar parts and miscellaneous steel products. Under the manufacturing services agreement entered into in 1994 and amended in 2005, ACF agreed to manufacture and distribute, at ARI’s instruction, various railcar components. In consideration for these services, ARI agreed to pay ACF based on agreed upon rates. The agreement automatically renews unless written notice is provided by ARI. Also in April 2015, ARI entered into a parts purchasing and sale agreement with ACF. The agreement was unanimously approved by the independent directors of ARI’s and Icahn Enterprises' audit committee. Under this agreement, ARI and ACF may, from time to time, purchase and sell to each other certain parts for railcars ("Railcar Parts"). ARI also provides a non-exclusive and non-assignable license of certain intellectual property related to the manufacture and sale of Railcar Parts to ARI. The buyer under the agreement must pay the market price of the parts as determined in the agreement or as stated on a public website for all ARI customers. ARI may provide designs, engineering and purchasing support, including all materials and components to ACF. Subject to certain early termination events, the agreement terminates on December 31, 2020. For the three months ended March 31, 2016 and 2015, ARI purchased $2 million and $3 million , respectively, of components from ACF. In January 2013, ARI entered into a purchasing and engineering services agreement and license with ACF. The agreement was unanimously approved by the independent directors of ARI’s and Icahn Enterprises' audit committee on the basis that the terms of the agreement were not materially less favorable to ARI than those that could have been obtained in a comparable transaction with an unrelated person. Under this agreement, ARI provides purchasing support and engineering services to ACF in connection with ACF’s manufacture and sale of tank railcars at its facility in Milton, Pennsylvania. Additionally, ARI has granted ACF a nonexclusive, non-assignable license to certain of ARI’s intellectual property, including certain designs, specifications, processes and manufacturing know-how required to manufacture and sell tank railcars during the term of the agreement. In November 2015, ARI and ACF amended this agreement to, among other provisions, extend the termination date to December 31, 2016 from December 31, 2015, subject to certain early termination events. In consideration for the services and license provided by ARI to ACF in conjunction with the agreement, ACF pays ARI a royalty and, if any, a share of the net profits ("ACF Profits") earned on each railcar manufactured and sold by ACF under the agreement, in an aggregate amount equal to 30% of such ACF Profits, as calculated under the agreement. ACF Profits are net of certain of ACF’s start-up and shutdown expenses and certain maintenance capital. If no ACF Profits are realized on a railcar manufactured and sold by ACF pursuant to the agreement, ARI will still be entitled to the royalty for such railcar and will not share in any losses incurred by ACF in connection therewith. In addition, any railcar components supplied by ARI to ACF for the manufacture of these railcars are provided at fair market value. Under the agreement, ACF had the exclusive right to manufacture and sell subject tank railcars for any new orders scheduled for delivery to customers on or before January 31, 2014. ARI has the exclusive right to any sales opportunities for such tank railcars for any new orders scheduled for delivery after that date and through termination of the agreement. ARI also has the right to assign any sales opportunity to ACF, and ACF has the right, but not the obligation, to accept such sales opportunity. Any sales opportunity accepted by ACF will not be reflected in ARI’s orders or backlog. ARI's revenues under this agreement were $1 million and $2 million for the three months ended March 31, 2016 and 2015, respectively, and were recorded for sales of railcar components to ACF and for royalties and profits on railcars sold by ACF. In April 2013, AEP Leasing entered into an agreement (the "ACF Agreement") with ACF whereby AEP Leasing would purchase railcars from ACF. The ACF Agreement was assumed by ARL in connection with our purchase of economic interest in ARL. The ACF Agreement was unanimously approved by Icahn Enterprises' audit committee consisting of independent directors, who were advised by independent counsel and an independent financial advisor on the basis that the terms were not less favorable than those terms that could have been obtained in a comparable transaction with an unaffiliated third party. Under this agreement, purchases of railcars from ACF were $9 million for the three months ended March 31, 2015. There were no purchase of railcars from ACF under this agreement for the three months ended March 31, 2016 . In addition to the above purchases, on a contract-by-contract basis, ARL purchased $12 million and $5 million of railcars from ACF for the three months ended March 31, 2016 and 2015, respectively. Insight Portfolio Group LLC Insight Portfolio Group LLC (“Insight Portfolio Group”) is an entity formed and controlled by Mr. Icahn in order to maximize the potential buying power of a group of entities with which Mr. Icahn has a relationship in negotiating with a wide range of suppliers of goods, services and tangible and intangible property at negotiated rates. In 2013, Icahn Enterprises Holdings acquired a minority equity interest in Insight Portfolio Group and agreed to pay a portion of Insight Portfolio Group's operating expenses. In addition to the minority equity interest held by Icahn Enterprises Holdings, certain subsidiaries of Icahn Enterprises Holdings, including Federal-Mogul, CVR, PSC Metals, ARI, ARL, Tropicana, Viskase and WPH also acquired minority equity interests in Insight Portfolio Group and agreed to pay a portion of Insight Portfolio Group's operating expenses. A number of other entities with which Mr. Icahn has a relationship also acquired equity interests in Insight Portfolio Group and also agreed to pay certain of Insight Portfolio Group's operating expenses. For each of the three months ended March 31, 2016 and 2015, immaterial amounts were paid in respect to certain of Insight Portfolio Group's operating expenses.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Fair Value Measurements . U.S. GAAP requires enhanced disclosures about investments and non-recurring non-financial assets and non-financial liabilities that are measured and reported at fair value and has established a hierarchal disclosure framework that prioritizes and ranks the level of market price observability used in measuring investments or non-financial assets and liabilities at fair value. Market price observability is impacted by a number of factors, including the type of investment and the characteristics specific to the investment. Investments with readily available active quoted prices or for which fair value can be measured from actively quoted prices generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. Investments and non-financial assets and/or liabilities measured and reported at fair value are classified and disclosed in one of the following categories: Level 1 - Quoted prices are available in active markets for identical investments as of the reporting date. The types of investments included in Level 1 include listed equities and listed derivatives. We do not adjust the quoted price for these investments, even in situations where we hold a large position. Level 2 - Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value is determined through the use of models or other valuation methodologies. Investments that are generally included in this category include corporate bonds and loans, less liquid and restricted equity securities and certain over-the-counter derivatives. The inputs and assumptions of our Level 2 investments are derived from market observable sources including reported trades, broker/dealer quotes and other pertinent data. Level 3 - Pricing inputs are unobservable for the investment and non-financial asset and/or liability and include situations where there is little, if any, market activity for the investment or non-financial asset and/or liability. The inputs into the determination of fair value require significant management judgment or estimation. Fair value is determined using comparable market transactions and other valuation methodologies, adjusted as appropriate for liquidity, credit, market and/or other risk factors. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to the investment. Significant transfers, if any, between the levels within the fair value hierarchy are recognized at the beginning of the reporting period when changes in circumstances require such transfers. The following table summarizes the valuation of our investments, derivative contracts, securities sold not yet purchased and other liabilities by the above fair value hierarchy levels measured on a recurring and non-recurring basis as of March 31, 2016 and December 31, 2015: March 31, 2016 December 31, 2015 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets (in millions) Investments (Note 4) $ 9,007 $ 430 $ 249 $ 9,686 $ 14,447 $ 289 $ 292 $ 15,028 Derivative contracts, at fair value (1) — 40 — 40 — 259 — 259 $ 9,007 $ 470 $ 249 $ 9,726 $ 14,447 $ 548 $ 292 $ 15,287 Liabilities Securities sold, not yet purchased $ 998 $ 54 $ — $ 1,052 $ 794 $ — $ — $ 794 Other liabilities — 1 — 1 — 3 — 3 Derivative contracts, at fair value (2) — 469 — 469 — 36 — 36 $ 998 $ 524 $ — $ 1,522 $ 794 $ 39 $ — $ 833 (1) Amounts are classified within other assets in our condensed consolidated balance sheets. (2) Amounts are classified within accrued expenses and other liabilities in our condensed consolidated balance sheets. Assets Measured at Fair Value on a Recurring Basis for Which We Use Level 3 Inputs to Determine Fair Value The changes in investments measured at fair value on a recurring basis for which we use Level 3 inputs to determine fair value are as follows: Three Months Ended March 31, 2016 2015 (in millions) Balance at January 1 $ 283 $ 229 Gross unrealized gains (losses) 16 (14 ) Purchases 50 — Transfers (out) in (122 ) 1 Balance at March 31 $ 227 $ 216 During the first quarter of 2016, we transferred out a Level 3 corporate debt investment in the amount of $126 million . See Note 2 , " Operating Units - Gaming," for further discussion regarding this transaction. During 2015, the Holding Company made a certain investment classified as trading securities, which is considered a Level 3 investment due to unobservable market data and is measured at fair value on a recurring basis. We purchased an additional $50 million of this investment during the three months ended March 31, 2016. We determined the fair value of this investment using internally developed models and other valuation techniques. As of March 31, 2016 and December 31, 2015, the fair value of this investment was $207 million and $157 million , respectively. There were no unrealized gains or losses included in earnings for the three months ended March 31, 2016 related to Level 3 investments still held at March 31, 2016 by our Investment and Gaming segments and the Holding Company. Assets Measured at Fair Value on a Non-Recurring Basis for Which We Use Level 3 Inputs to Determine Fair Value We have certain investments in debt securities classified as held-to-maturity within our Gaming segment since we have the ability and intent to hold the bonds to maturity. The debt securities are classified as Level 3 investments measured at fair value on a non-recurring basis and therefore are excluded from the roll forward of Level 3 investments measured on a recurring basis above. As of March 31, 2016 and December 31, 2015, the fair value of these debt securities was $22 million and $9 million , respectively, with the increase resulting from our acquisition of Trump during the first quarter of 2016. During the three months ended March 31, 2016 , our Energy segment recorded a goodwill impairment charge of 574 million , which represented the full amount of the remaining goodwill allocated to this segment. Refer to Note 8 , " Goodwill and Intangible Assets, Net ," for further discussion. Additionally, during the three months ended March 31, 2016 , our Automotive segment recorded $3 million of impairment relating to property, plant and equipment.

Financial Instruments

Financial Instruments [Abstract]
Financial Instruments	Financial Instruments . Certain derivative contracts with a single counterparty executed by the Investment Funds, by our Automotive segment with a single counterparty or by our Energy segment with a single counterparty, or by our Holding Company with a single counterparty are reported on a net-by-counterparty basis where a legal right of offset exists under an enforceable netting agreement. Values for the derivative financial instruments, principally swaps, forwards, over-the-counter options and other conditional and exchange contracts, are reported on a net-by-counterparty basis. As a result, the net exposure to counterparties is reported in either other assets or accrued expenses and other liabilities in our condensed consolidated balance sheets. Investment Segment and Holding Company The Investment Funds currently maintain cash deposits and cash equivalents with financial institutions. Certain account balances may not be covered by the Federal Deposit Insurance Corporation, while other accounts may exceed federally insured limits. The Investment Funds have prime broker arrangements in place with multiple prime brokers as well as a custodian bank. The Investment Funds also have relationships with several financial institutions with which they trade derivative and other financial instruments. In the normal course of business, the Investment Funds and the Holding Company may trade various financial instruments and enter into certain investment activities, which may give rise to off-balance-sheet risks, with the objective of capital appreciation or as economic hedges against other securities or the market as a whole. The Investment Funds' and the Holding Company's investments may include futures, options, swaps and securities sold, not yet purchased. These financial instruments represent future commitments to purchase or sell other financial instruments or to exchange an amount of cash based on the change in an underlying instrument at specific terms at specified future dates. Risks arise with these financial instruments from potential counterparty non-performance and from changes in the market values of underlying instruments. Securities sold, not yet purchased, at fair value represent obligations to deliver the specified security, thereby creating a liability to repurchase the security in the market at prevailing prices. Accordingly, these transactions result in off-balance-sheet risk, as the satisfaction of the obligations may exceed the amount recognized in our condensed consolidated balance sheets. Our investments in securities and amounts due from brokers are partially restricted until we satisfy the obligation to deliver the securities sold, not yet purchased. The Investment Funds and the Holding Company may enter into derivative contracts, including swap contracts, futures contracts and option contracts. The Investment Funds may also enter into foreign currency derivative contracts with the objective of capital appreciation or to economically hedge against foreign currency exchange rate risks on all or a portion of their non-U.S. dollar denominated investments. The Investment Funds and the Holding Company have entered into various types of swap contracts with other counterparties. These agreements provide that they are entitled to receive or are obligated to pay in cash an amount equal to the increase or decrease, respectively, in the value of the underlying shares, debt and other instruments that are the subject of the contracts, during the period from inception of the applicable agreement to its expiration. In addition, pursuant to the terms of such agreements, they are entitled to receive or obligated to pay other amounts, including interest, dividends and other distributions made in respect of the underlying shares, debt and other instruments during the specified time frame. They are also required to pay to the counterparty a floating interest rate equal to the product of the notional amount multiplied by an agreed-upon rate, and they receive interest on any cash collateral that they post to the counterparty at the federal funds or LIBOR rate in effect for such period. The Investment Funds and the Holding Company may trade futures contracts. A futures contract is a firm commitment to buy or sell a specified quantity of a standardized amount of a deliverable grade commodity, security, currency or cash at a specified price and specified future date unless the contract is closed before the delivery date. Payments (or variation margin) are made or received by the Investment Funds and the Holding Company each day, depending on the daily fluctuations in the value of the contract, and the whole value change is recorded as an unrealized gain or loss by the Investment Funds and the Holding Company. When the contract is closed, the Investment Funds and the Holding Company record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. The Investment Funds and the Holding Company may utilize forward contracts to seek to protect their assets denominated in foreign currencies and precious metals holdings from losses due to fluctuations in foreign exchange rates and spot rates. The Investment Funds' and the Holding Company's exposure to credit risk associated with non-performance of such forward contracts is limited to the unrealized gains or losses inherent in such contracts, which are recognized in other assets and accrued expenses and other liabilities in our condensed consolidated balance sheets. The Investment Funds may also enter into foreign currency contracts for purposes other than hedging denominated securities. When entering into a foreign currency forward contract, the Investment Funds agree to receive or deliver a fixed quantity of foreign currency for an agreed-upon price on an agreed-upon future date unless the contract is closed before such date. The Investment Funds record unrealized gains or losses on the contracts as measured by the difference between the forward foreign exchange rates at the dates of entry into such contracts and the forward rates at the reporting date. The Investment Funds may also purchase and write option contracts. As a writer of option contracts, the Investment Funds receive a premium at the outset and then bear the market risk of unfavorable changes in the price of the underlying financial instrument. As a result of writing option contracts, the Investment Funds are obligated to purchase or sell, at the holder's option, the underlying financial instrument. Accordingly, these transactions result in off-balance-sheet risk, as the Investment Funds' satisfaction of the obligations may exceed the amount recognized in our condensed consolidated balance sheets. At March 31, 2016 , the maximum payout amounts relating to certain put options written by the Investment Funds were $830 million , of which $830 million related to covered put options on existing short positions on certain stock and credit indices. At December 31, 2015, the maximum payout amounts relating to certain put options written by the Investment Funds were approximately $5.9 billion , of which approximately $5.9 billion related to covered put options on existing short positions on certain stock and credit indices. As of March 31, 2016 and December 31, 2015, there were unrealized gains of $10 million and $67 million , respectively, with respect to these put options. Certain terms of the Investment Funds' contracts with derivative counterparties, which are standard and customary to such contracts, contain certain triggering events that would give the counterparties the right to terminate the derivative instruments. In such events, the counterparties to the derivative instruments could request immediate payment on derivative instruments in net liability positions. The aggregate fair value of all of the Investment Funds' derivative instruments with credit-risk-related contingent features that are in a liability position at March 31, 2016 and December 31, 2015 was $467 million and $33 million , respectively. At March 31, 2016 and December 31, 2015, the Investment Funds had approximately $476 million and $883 million , respectively, posted as collateral for derivative positions, including those derivative instruments with credit-risk-related contingent features; these amounts are included in cash held at consolidated affiliated partnerships and restricted cash in our condensed consolidated balance sheets. U.S. GAAP requires the disclosure of information about obligations under certain guarantee arrangements. Such guarantee arrangements requiring disclosure include contracts that contingently require the guarantor to make payments to the guaranteed party based on another entity's failure to perform under an agreement as well as indirect guarantees of the indebtedness of others. Each Investment Fund's assets may be held in one or more accounts maintained for the Investment Fund by its prime brokers or at other brokers or custodian banks, which may be located in various jurisdictions. The prime brokers, brokers and custodian banks are subject to various laws and regulations in the relevant jurisdictions in the event of their insolvency. Accordingly, the practical effect of these laws and their application to the Investment Funds' assets may be subject to substantial variations, limitations and uncertainties. The insolvency of any of the prime brokers, brokers, custodian banks or clearing corporations may result in the loss of all or a substantial portion of the Investment Funds' assets or in a significant delay in the Investment Funds' having access to those assets. Credit concentrations may arise from investment activities and may be impacted by changes in economic, industry or political factors. The Investment Funds and the Holding Company routinely execute transactions with counterparties in the financial services industry, resulting in credit concentration with respect to this industry. In the ordinary course of business, the Investment Funds and the Holding Company may also be subject to a concentration of credit risk to a particular counterparty. The Investment Funds and the Holding Company seek to mitigate these risks by actively monitoring exposures, collateral requirements and the creditworthiness of our counterparties. Automotive Commodity Price Risk Federal-Mogul's production processes are dependent upon the supply of certain raw materials that are exposed to price fluctuations on the open market. The primary purpose of Federal-Mogul's commodity price forward contract activity is to manage the volatility associated with forecasted purchases. Federal-Mogul monitors its commodity price risk exposures regularly to maximize the overall effectiveness of its commodity forward contracts. Principal raw materials hedged include copper, nickel, tin, zinc, high-grade aluminum and aluminum alloy. Forward contracts are used to mitigate commodity price risk associated with raw materials, generally related to purchases forecast for up to 15 months in the future. Federal-Mogul had commodity price hedge contracts outstanding with combined notional values of $21 million and $28 million at March 31, 2016 and December 31, 2015, respectively, substantially all of which mature within one year in each of the respective periods and all of which were designated as hedging instruments for accounting purposes. Federal-Mogul had a net liability balance of $2 million and $3 million as of March 31, 2016 and December 31, 2015, respectively, with respect to these hedging positions. Unrealized net losses of $2 million and $2 million were recorded in accumulated other comprehensive loss as of March 31, 2016 and December 31, 2015, respectively. Foreign Currency Risk Federal-Mogul manufactures and sells its products in North America, South America, Asia, Europe and Africa. As a result, Federal-Mogul's financial results could be significantly affected by factors such as changes in foreign currency exchange rates or weak economic conditions in foreign markets in which it manufactures and sells its products. Federal-Mogul's operating results are primarily exposed to changes in exchange rates between the U.S. dollar and various global currencies. Federal-Mogul generally tries to use natural hedges within its foreign currency activities, including the matching of revenues and costs, to minimize foreign currency risk. Where natural hedges are not in place, Federal-Mogul considers managing certain aspects of its foreign currency activities and larger transactions through the use of foreign currency options or forward contracts. Principal currencies hedged have historically included the euro, British pound and Polish zloty. Foreign currency forwards are also used in conjunction with Federal-Mogul's commodity hedging program. As part of its hedging program, Federal-Mogul attempts to limit hedge ineffectiveness by matching terms of the commodity purchases with the hedging instrument. Federal-Mogul does not hold any foreign currency price hedge contracts as of March 31, 2016 or December 31, 2015. Concentrations of Credit Risk Financial instruments including cash equivalents, derivative contracts, and accounts receivable, expose Federal-Mogul to counter-party credit risk for non-performance. Federal-Mogul’s counterparties for cash equivalents and derivative contracts are banks and financial institutions that meet its requirement of high credit standing. Federal-Mogul's counterparties for derivative contracts are substantial investment and commercial banks with significant experience using such derivatives. Federal-Mogul manages its credit risk through policies requiring minimum credit standing and limiting credit exposure to any one counter-party and through monitoring counter-party credit risks. Federal-Mogul's concentration of credit risk related to derivative contracts at March 31, 2016 and December 31, 2015 was not material. Energy CVR is subject to price fluctuations caused by supply conditions, weather, economic conditions, interest rate fluctuations and other factors. To manage price risk on crude oil and other inventories and to fix margins on certain future production, CVR from time to time enters into various commodity derivative transactions. CVR has adopted accounting standards that impose extensive record-keeping requirements in order to designate a derivative financial instrument as a hedge. CVR holds derivative instruments, such as exchange-traded crude oil futures and certain over-the-counter forward swap agreements, which it believes provide an economic hedge on future transactions, but such instruments are not designated as hedges for GAAP purposes. Gains or losses related to the change in fair value and periodic settlements of these derivative instruments are included in other income (loss), net in the condensed consolidated statements of operations. Commodity Swaps CVR Refining enters into commodity swap contracts in order to fix the margin on a portion of future production. The physical volumes are not exchanged and these contracts are net settled with cash. The contract fair value of the commodity swaps is reflected on the condensed consolidated balance sheets with changes in fair value currently recognized in the condensed consolidated statement of operations. Quoted prices for similar assets or liabilities in active markets (Level 2) are considered to determine the fair values for the purpose of marking to market the hedging instruments at each period end. At December 31, 2015, CVR had open commodity hedging instruments consisting of 2.5 million barrels of crack spreads primarily to fix the margin on a portion of its future gasoline and distillate production. During the first quarter of 2016, CVR Refining settled a number of the open crack spread positions and entered into offsetting positions to effectively lock in the gain on the remaining positions to be settled in 2016. At March 31, 2016 , CVR had open commodity hedging instruments consisting of 0.6 million barrels net of crack spreads and 1.0 million barrels of price and basis swaps. The fair value of the outstanding contracts at March 31, 2016 and December 31, 2015 was a net asset of $22 million and $45 million , respectively. For the three months ended March 31, 2016 and 2015, CVR recognized a net loss of $1 million and $50 million , respectively, which is included in other income (loss), net in the condensed consolidated statements of operations. Interest Rate Swaps Coffeyville Resources Nitrogen Fertilizers, LLC ("CRNF") had two floating-to-fixed interest rate swap agreements for the purpose of hedging the interest rate risk associated with a portion of its $125 million floating rate term debt, which matures in April 2016. The aggregate notional amount covered under these agreements totals $63 million (split evenly between the two agreements) and commenced on August 12, 2011 and expired on February 12, 2016. The interest rate swaps agreements terminated in February 2016. The realized losses on the interest rate swaps reclassified from accumulated other comprehensive loss into interest expense was less than $1 million for each of the three months ended March 31, 2016 and 2015. Consolidated Derivative Information The volume of our derivative activities based on their notional exposure, categorized by primary underlying risk, is as follows: March 31, 2016 December 31, 2015 Long Notional Exposure Short Notional Exposure Long Notional Exposure Short Notional Exposure Primary underlying risk: (in millions) Credit swaps (1) $ 192 $ 917 $ 187 $ 2,306 Equity swaps 209 15,325 1,343 14,167 Foreign currency forwards — 883 — 842 Interest rate swap contracts (2) — 63 — 137 Commodity contracts 26 1,220 43 643 (1) The short notional amount on our credit default swap positions is approximately $4.1 billion and $10.0 billion as of March 31, 2016 and December 31, 2015, respectively. However, because credit spreads cannot compress below zero, our downside short notional exposure to loss is approximately $0.9 billion and $2.3 billion as of March 31, 2016 and December 31, 2015, respectively.

We utilize the straight-line method of amortization, recognized over the estimated useful lives of the assets. For our segments discussed below, the fair values of our reporting units are based upon consideration of various valuation methodologies, one of which is projecting future cash flows discounted at rates commensurate with the risks involved (“Discounted Cash Flow” or “DCF”). Assumptions used in a DCF require the exercise of significant judgment, including judgment about appropriate discount rates and terminal values, growth rates, and the amount and timing of expected future cash flows. The forecasted cash flows are based on current plans and for years beyond that plan, the estimates are based on assumed growth rates. We believe that our assumptions are consistent with the plans and estimates used to manage the underlying businesses. The discount rates, which are intended to reflect the risks inherent in future cash flow projections, used in a DCF are based on estimates of the weighted-average cost of capital of a market participant. Such estimates are derived from our analysis of peer companies and consider the industry weighted average return on debt and equity from a market participant perspective. Automotive As further discussed in Note 2 , " Operating Units - Automotive," during the first quarter of 2016, we acquired Pep Boys and allocated $85 million to trademarks and brand names, $25 million to customer relationships and $252 million to goodwill as of the acquisition date. We are in the process of valuing the Pep Boys acquisition and have recorded provisional amounts based on preliminary estimates of fair value of net assets acquired, including goodwill. The provisional measurements of net assets are subject to change as we finalize the purchase price allocation. The Pep Boys acquisition is not material to our condensed consolidated financial statements. We perform the annual goodwill impairment test for our Automotive segment as of October 1 of each year, or more frequently if impairment indicators exist. Based on "Step 2" of the goodwill impairment analysis of our Automotive segment's Motorparts reporting unit, we recorded a goodwill impairment charge of $312 million for the year ended December 31, 2015. Due to the complexity in the "Step 2" goodwill impairment analysis, we are currently expecting to finalize our Automotive segment's goodwill impairment for the Motorparts reporting unit during the second quarter of 2016 and any resulting difference in the amount of the impairment will be adjusted at that time. Energy Due to worsening sales trends for our Energy segment's Petroleum reporting unit, we performed an interim goodwill impairment analysis during the first quarter of 2016. Based on this analysis, our Energy segment recognized a goodwill impairment charge of $574 million , which represented the full amount of the remaining goodwill allocated to the Petroleum reporting unit. Due to the complexity in the "Step 2" goodwill impairment test performed during the first quarter of 2016, we expect to finalize the assessment of our Energy segment's goodwill impairment during the second quarter of 2016 and any resulting difference in the amount of the impairment will be adjusted at that time. We perform the annual goodwill impairment test for our Energy segment as of April 30 of each year, or more frequently if impairment indicators exist. Due to worsening sales trends for our Energy segment's Fertilizer reporting unit, we performed an interim goodwill impairment analysis during the fourth quarter of 2015. Based on "Step 2" of the goodwill impairment analysis of our Energy segment's Fertilizer reporting unit, we recorded a goodwill impairment charge of $253 million for the year ended December 31, 2015, which represented the full amount of the remaining goodwill allocated to the Fertilizer reporting unit. Due to the complexity in the "Step 2" goodwill impairment test performed during the fourth quarter of 2015, we finalized the assessment of our Energy segment's goodwill impairment for the Fertilizer reporting unit during the first quarter of 2016 and noted that no additional adjustments to goodwill were required for the first quarter of 2016. Railcar We perform the annual goodwill impairment test as of November 1 of each year for our Railcar segment. For purposes of goodwill impairment testing, our Railcar segment's manufacturing reporting unit is the only reporting unit with allocated goodwill. We assess qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is greater than its carrying amount. If, however, we had determined that it was more likely than not that the fair value of the reporting unit was less than its carrying amount, then we would perform the first step of the two-step goodwill impairment test. In evaluating whether it is more likely than not that the fair value of the reporting unit is greater than its carrying amount, we considered various qualitative and quantitative factors, including macroeconomic conditions, railcar industry trends and the fact that our railcar manufacturing reporting unit has historical positive operating cash flows that we anticipate will continue. After assessing these factors, we determined that it was more likely than not the fair value of our railcar manufacturing reporting unit was greater than its carrying amount, and therefore no further testing was necessary. Gaming As further discussed in Note 2 , " Operating Units - Gaming," during the first quarter of 2016, we acquired Trump and allocated $17 million to trademarks and brand names as of the acquisition date. We are in the process of valuing the Trump acquisition and have recorded provisional amounts based on preliminary estimates of fair value of net assets acquired. The provisional measurements of net assets are subject to change as we finalize the purchase price allocation. The Trump acquisition is not material to our condensed consolidated financial statements.

Debt Facilities - Automotive Federal-Mogul During the first quarter of 2016, Federal-Mogul increased its borrowing capacity under its revolving credit facility by $50 million to $600 million . As of March 31, 2016 and December 31, 2015, the outstanding balance on Federal-Mogul's revolving credit facility was $390 million and $340 million , respectively. As of March 31, 2016 and December 31, 2015, the borrowing availability under Federal-Mogul's revolving credit facility was $170 million and $170 million , respectively.

LP Unit Distributions On February 23, 2016, Icahn Enterprises declared a quarterly distribution in the amount of $1.50 per depositary unit in which each depositary unit holder had the option to make an election to receive either cash or additional depositary units. As a result, on April 12, 2016, Icahn Enterprises distributed an aggregate 2,824,186 depositary units to unit holders electing to receive depositary units in connection with this distribution. Mr. Icahn and his affiliates elected to receive a majority of their proportionate share of these distributions in depositary units. As of May 5, 2016 , Mr. Icahn and his affiliates owned 89.3% of Icahn Enterprises outstanding depositary units. Because the depositary unit holder has the election to receive the distribution either in cash or additional depositary units, we recorded a unit distribution liability of $202 million on our condensed consolidated balance sheets as the unit distribution had not been made as of March 31, 2016 . In addition, the unit distribution liability, which is included in accrued expenses and other liabilities in the condensed consolidated balance sheets, is considered a potentially dilutive security and is considered in the calculation of diluted income per LP unit as disclosed above. However, as their effect would be anti-dilutive, 1 million weighted average units have been excluded from the calculation of diluted income per LP unit for the three months ended March 31, 2016 . Any difference between the liability recorded and the amount representing the aggregate value of the number of depositary units distributed and cash paid would be charged to equity.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes . For the three months ended March 31, 2016 , each of Icahn Enterprises and Icahn Enterprises Holdings recorded an income tax expense of $16 million on pre-tax loss of $1.6 billion compared to an income tax expense of $49 million on pre-tax income of $471 million for the three months ended March 31, 2015 . Our effective income tax rate was (1.0)% and 10.4% for the three months ended March 31, 2016 and 2015, respectively. For the three months ended March 31, 2016 , the effective tax rate was lower than the statutory federal rate of 35% , primarily due to partnership losses for which there was no tax benefit, as such losses are allocated to the partners, and goodwill impairment not deductible for tax purposes. For the three months ended March 31, 2015 , the effective tax rate was lower than the statutory federal rate of 35% , primarily due to partnership income not subject to taxation, as such taxes are the responsibility of the partners.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies . Automotive Environmental Matters Federal-Mogul is a defendant in lawsuits filed, or the recipient of administrative orders issued or demand letters received, in various jurisdictions pursuant to the Federal Comprehensive Environmental Response Compensation and Liability Act of 1980 (“CERCLA”) or other similar national, provincial or state environmental remedial laws. These laws provide that responsible parties may be liable to pay for remediating contamination resulting from hazardous substances that were discharged into the environment by them, by prior owners or occupants of property they currently own or operate, or by others to whom they sent such substances for treatment or other disposition at third party locations. Federal-Mogul has been notified by the United States Environmental Protection Agency, other national environmental agencies, and various provincial and state agencies that it may be a potentially responsible party (“PRP”) under such laws for the cost of remediating hazardous substances pursuant to CERCLA and other national and state or provincial environmental laws. PRP designation often results in the funding of site investigations and subsequent remedial activities. Many of the sites that are likely to be the costliest to remediate are often current or former commercial waste disposal facilities to which numerous companies sent wastes. Despite the potential joint and several liability that might be imposed on Federal-Mogul under CERCLA and some of the other laws pertaining to these sites, its share of the total waste sent to these sites has generally been small. Federal-Mogul believes its exposure for liability at these sites is limited. Federal-Mogul has also identified certain other present and former properties at which it may be responsible for cleaning up or addressing environmental contamination, in some cases as a result of contractual commitments and/or federal or state environmental laws. Federal-Mogul is actively seeking to resolve these actual and potential statutory, regulatory and contractual obligations. Although difficult to quantify based on the complexity of the issues, Federal-Mogul has accrued amounts corresponding to its best estimate of the costs associated with such regulatory and contractual obligations on the basis of available information from site investigations and best professional judgment of consultants. Total environmental liabilities, determined on an undiscounted basis, were $14 million and $14 million as of March 31, 2016 and December 31, 2015, respectively, and are included in accrued expenses and other liabilities in our condensed consolidated balance sheets. Federal-Mogul believes that recorded environmental liabilities will be adequate to cover its estimated liability for its exposure in respect to such matters. In the event that such liabilities were to significantly exceed the amounts recorded by Federal-Mogul, our Automotive segment's results of operations could be materially affected. At March 31, 2016 , Federal-Mogul estimates reasonably possible material additional losses, above and beyond its best estimate of required remediation costs as recorded, to approximate $43 million . Asset Retirement Obligations Federal-Mogul has identified sites with contractual obligations and several sites that are closed or expected to be closed and sold. In connection with these sites, Federal-Mogul has accrued $16 million and $16 million as of March 31, 2016 and December 31, 2015, respectively, for asset retirement obligations ("ARO"), primarily related to anticipated costs of removing hazardous building materials at its facilities, and has considered impairment issues that may result from capitalization of these ARO amounts. Federal-Mogul has conditional asset retirement obligations ("CARO"), primarily related to removal costs of hazardous materials in buildings, for which it believes reasonable cost estimates cannot be made at this time because it does not believe it has a reasonable basis to assign probabilities to a range of potential settlement dates for these retirement obligations. Accordingly, Federal-Mogul is currently unable to determine amounts to accrue for CARO at such sites. Other Matters On April 25, 2014, a group of plaintiffs brought an action against Federal-Mogul Products, Inc. (“F-M Products”), a wholly-owned subsidiary of Federal-Mogul, alleging injuries and damages associated with the discharge of chlorinated hydrocarbons by the former owner of a facility located in Kentucky. Since 1998, when F-M Products acquired the facility, it has been cooperating with the applicable regulatory agencies on remediating the prior discharges pursuant to an order entered into by the facility’s former owner. Federal-Mogul is unable to estimate any reasonably possible range of loss for reasons including that the plaintiffs did not claim any amount of damages in their complaint. F-M Products intends to vigorously defend this litigation. Energy Unconditional Purchase Obligations CVR leases various equipment, including railcars, and real properties under long-term operating leases expiring at various dates. For each of the three months ended March 31, 2016 and 2015 lease expense was $2 million . The lease agreements have various remaining terms. Some agreements are renewable, at CVR's option, for additional periods. It is expected, in the ordinary course of business, that leases will be renewed or replaced as they expire. Additionally, in the normal course of business, CVR has long-term commitments to purchase oxygen, nitrogen, electricity, storage capacity and pipeline transportation services. Crude Oil Supply Agreement On August 31, 2012, Coffeyville Resources Refining & Marketing, LLC ("CRRM"), and Vitol Inc. ("Vitol") entered into an Amended and Restated Crude Oil Supply Agreement (the "Vitol Agreement"). Under the Vitol Agreement, Vitol supplies the petroleum business with crude oil and intermediation logistics, which helps to reduce the Refining Partnership's inventory position and mitigate crude oil pricing risk. The Vitol Agreement will automatically renew for successive one-year terms (each such term, a "Renewal Term") unless either party provides the other with notice of nonrenewal at least 180 days prior to the expiration of any Renewal Term. The Vitol Agreement currently extends through December 31, 2016. Litigation From time to time, CVR is involved in various lawsuits arising in the normal course of business, including matters such as those described below under "Environmental, Health and Safety Matters." Liabilities related to such litigation are recognized when the related costs are probable and can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. It is possible that management’s estimates of the outcomes will change due to uncertainties inherent in litigation and settlement negotiations. Except as described below for our Energy segment, there were no new proceedings or material developments in proceedings that we previously reported in our annual report on Form 10-K for the year ended December 31, 2015. In the opinion of CVR's management, the ultimate resolution of any other litigation matters is not expected to have a material adverse effect on the accompanying condensed consolidated financial statements. There can be no assurance that management’s beliefs or opinions with respect to liability for potential litigation matters are accurate. Environmental, Health and Safety Matters ("EHS") The petroleum and nitrogen fertilizer businesses are subject to various stringent federal, state, and local EHS rules and regulations. Liabilities related to EHS matters are recognized when the related costs are probable and can be reasonably estimated. Estimates of these costs are based upon currently available facts, existing technology, site-specific costs, and currently enacted laws and regulations. In reporting EHS liabilities, no offset is made for potential recoveries. CRRM, CRNF, Coffeyville Resources Crude Transportation, LLC ("CRCT"), Wynnewood Refining Company, LLC ("WRC") and Coffeyville Resources Terminal, LLC ("CRT") own and/or operate manufacturing and ancillary operations at various locations directly related to petroleum refining and distribution and nitrogen fertilizer manufacturing. Therefore, CRRM, CRNF, CRCT, WRC and CRT have exposure to potential EHS liabilities related to past and present EHS conditions at these locations. Under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"), the Resource Conservation and Recovery Act ("RCRA"), and related state laws, certain persons may be liable for the release or threatened release of hazardous substances. These persons can include the current owner or operator of property where a release or threatened release occurred, any persons who owned or operated the property when the release occurred, and any persons who disposed of, or arranged for the transportation or disposal of, hazardous substances at a contaminated property. Liability under CERCLA is strict, and under certain circumstances, joint and several, so that any responsible party may be held liable for the entire cost of investigating and remediating the release of hazardous substances. Similarly, the Oil Pollution Act generally subjects owners and operators of facilities to strict, joint and several liability for all containment and clean-up costs, natural resource damages, and potential governmental oversight costs arising from oil spills into the waters of the United States, which has been broadly interpreted to include most water bodies including intermittent streams. CRRM, CRNF, CRCT, WRC and CRT are subject to extensive and frequently changing federal, state and local environmental and health and safety laws and regulations governing the emission and release of hazardous substances into the environment, the treatment and discharge of waste water, and the storage, handling, use and transportation of petroleum and nitrogen products, and the characteristics and composition of gasoline and diesel fuels. The ultimate impact of complying with evolving laws and regulations is not always clearly known or determinable due in part to the fact that our operations may change over time and certain implementing regulations for laws, such as the federal Clean Air Act, have not yet been finalized, are under governmental or judicial review or are being revised. These laws and regulations could result in increased capital, operating and compliance costs. As previously reported in our 2015 Form 10-K, the petroleum and nitrogen fertilizer businesses are party to, or otherwise subject to administrative orders and consent decrees with federal, state and local environmental authorities, as applicable, addressing corrective actions under RCRA, the Clean Air Act and the Clean Water Act. The petroleum business also is subject to (i) the Mobile Source Air Toxic II ("MSAT II") rule which requires reductions of benzene in gasoline; (ii) the Renewable Fuel Standard ("RFS"), which requires refiners to either blend "renewable fuels" in with their transportation fuels or purchase renewable fuel credits, known as RINs, in lieu of blending; and (iii) "Tier 3" gasoline sulfur standards. Except as otherwise described below, there have been no new developments or material changes to the environmental accruals or expected capital expenditures related to compliance with the foregoing environmental matters from those provided in our 2015 Form 10-K. CRRM, CRNF, CRCT, WRC and CRT each believe it is in substantial compliance with existing EHS rules and regulations. There can be no assurance that the EHS matters described or referenced herein or other EHS matters which may develop in the future will not have a material adverse effect on our Energy segment's business, financial condition, or results of operations. As of both March 31, 2016 and December 31, 2015, our Energy segment had environmental accruals of $4 million . CVR's management periodically reviews and, as appropriate, revises its environmental accruals. Based on current information and regulatory requirements, CVR's management believes that the accruals established for environmental expenditures are adequate. Environmental expenditures are capitalized when such expenditures are expected to result in future economic benefits. For the three months ended March 31, 2016 and 2015, capital expenditures were $4 million and $11 million , respectively, and were incurred for environmental compliance and efficiency of the operations. The cost of RINs for three months ended March 31, 2016 and 2015 was $43 million and $37 million , respectively. As of March 31, 2016 and December 31, 2015, the petroleum business' biofuel blending obligation was $24 million and $10 million , respectively, which was recorded in accrued expenses and other liabilities on the condensed consolidated balance sheets. Metals Environmental Matters Certain of PSC Metals' facilities are environmentally impaired in part as a result of operating practices at the sites prior to their acquisition by PSC Metals and as a result of PSC Metals' operations. PSC Metals has established procedures to periodically evaluate these sites, giving consideration to the nature and extent of the contamination. PSC Metals has provided for the remediation of these sites based upon management's judgment and prior experience. PSC Metals has estimated the liability to remediate these sites to be $28 million and $29 million at March 31, 2016 and December 31, 2015, respectively. Management believes, based on past experience, that the vast majority of these environmental liabilities and costs will be assessed and paid over an extended period of time. PSC Metals believes that it will be able to fund such costs in the ordinary course of business. Estimates of PSC Metals' liability for remediation of a particular site and the method and ultimate cost of remediation require a number of assumptions that are inherently difficult to make, and the ultimate outcome may be materially different from current estimates. Moreover, because PSC Metals has disposed of waste materials at numerous third-party disposal facilities, it is possible that PSC Metals will be identified as a PRP at additional sites. The impact of such future events cannot be estimated at the current time. PSC Metals has been designated as a PRP under U.S. federal and state superfund laws with respect to certain sites with which PSC Metals may have had a direct or indirect involvement. It is alleged that PSC Metals and its subsidiaries or their predecessors transported waste to the sites, disposed of waste at the sites or operated the sites in question. In addition, PSC Metals recently learned that its Knoxville location was the subject of investigations by the State of Tennessee under the federal Superfund law. These investigations were performed by the State of Tennessee pursuant to a contract with the EPA. PSC Metals is exploring a potential settlement of the matter. Currently, PSC Metals cannot assess the impact of any cost or liability associated with these investigations. With respect to all other matters in which PSC Metals has been designated as a PRP under U.S. federal and state superfund laws, PSC Metals has reviewed the nature and extent of the allegations, the number, connection and financial ability of other named and unnamed PRPs and the nature and estimated cost of the likely remedy. Based on reviewing the nature and extent of the allegations, PSC Metals has estimated its liability to remediate these sites to be immaterial at each of March 31, 2016 and December 31, 2015. If it is determined that PSC Metals has liability to remediate those sites and that more expensive remediation approaches are required in the future, PSC Metals could incur additional obligations, which could be material. In November and December of 2011, PSC Metals received three notices of violation ("NOV") from the Missouri Department of Natural Resources (“MDNR”) for hazardous waste and water violations related to its Festus, Missouri location. PSC Metals has entered into a settlement with MDNR that resolves these NOVs. Currently, PSC Metals believes that it has established adequate reserves for the cost of this settlement. In addition, PSC Metals believes that it has a claim for indemnification against the prior owner of the facility associated with the above-referenced notices of violation. MDNR and PSC Metals, as part of the resolution of MDNR's NOVs, have undertaken sampling for lead at residences near PSC Metals' Festus yard. Approximately 67 residences were sampled and tested, and of those, approximately 15 tested above residential standards for lead contamination. PSC Metals has entered into a settlement agreement with MDNR which resolves MNDR’s claims and requires limited soil remediation at the 15 residences. PSC Metals is in the process of completing the remediation required by the settlement agreement. Currently, PSC Metals believes that it has adequately reserved for the cost of remediation associated with its Festus yard and the residential areas near the yard. However, PSC Metals cannot assess its liability with certainty at this time. Additionally, PSC Metals believes that liability for off-site contamination was retained by the prior owner of the Festus yard and accordingly, it would have a claim for indemnification against the prior owner. In late February 2016, the PSC Metals shredder in Beaver Falls, Pennsylvania unknowingly processed scrap obtained from a third party containing radioactive material. Processing and transfer of that material resulted in the contamination of equipment there, and two other PSC Metals facilities. PSC Metals notified the appropriate governmental authorities and is working with those agencies and qualified specialist companies to properly remediate the contaminated facilities and dispose of the contaminated material. PSC Metals believes that the cost of the remediation effort and any business interruption costs are covered by insurance and its financial exposure would be immaterial. Railcar On October 24, 2014, ARI filed a complaint in United States District Court for the Southern District of New York against Gyansys, Inc. ("Gyansys"). The complaint asserts a claim against Gyansys for breaching its contract with ARI to implement an enterprise resource planning system. ARI seeks to recover monetary damages in an amount still to be determined, but which ARI alleged exceeds $25 million . Gyansys filed a response to the suit denying its responsibility. It also counterclaimed against ARI for a breach of contract and wrongful termination, seeking damages in excess of $10 million and equitable relief. At this time, ARI does not have sufficient information to reasonably form an estimate of the potential outcome (gain or loss) of this litigation. On September 12, 2015, the court denied ARI's motion to dismiss the wrongful termination counterclaim. A trial date has been tentatively scheduled for September 16, 2016. However, ARI believes that Gyansys' counterclaims lack merit and will continue to vigorously defend against these counterclaims. Other Matters Mr. Icahn, through certain affiliates, owns 100% of Icahn Enterprises GP and approximately 89.1% of Icahn Enterprises' outstanding depositary units as of March 31, 2016 . Applicable pension and tax laws make each member of a “controlled group” of entities, generally defined as entities in which there is at least an 80% common ownership interest, jointly and severally liable for certain pension plan obligations of any member of the controlled group. These pension obligations include ongoing contributions to fund the plan, as well as liability for any unfunded liabilities that may exist at the time the plan is terminated. In addition, the failure to pay these pension obligations when due may result in the creation of liens in favor of the pension plan or the Pension Benefit Guaranty Corporation ("PBGC") against the assets of each member of the controlled group. As a result of the more than 80% ownership interest in us by Mr. Icahn’s affiliates, we and our subsidiaries are subject to the pension liabilities of entities in which Mr. Icahn has a direct or indirect ownership interest of at least 80%. As a result of our ownership of more than 80% in our subsidiaries, we and our subsidiaries are subject to the pension liabilities of all entities in which Mr. Icahn has a direct or indirect ownership interest of at least 80%. ACF and Federal-Mogul, are the sponsors of several pension plans. All the minimum funding requirements of the Code and the Employee Retirement Income Security Act of 1974, as amended by the Pension Protection Act of 2006, for these plans have been met as of March 31, 2016 and December 31, 2015. If the plans were voluntarily terminated, they would be underfunded by approximately $584 million and $589 million as of March 31, 2016 and December 31, 2015, respectively. These results are based on the most recent information provided by the plans’ actuaries. These liabilities could increase or decrease, depending on a number of factors, including future changes in benefits, investment returns, and the assumptions used to calculate the liability. As members of the controlled group, we would be liable for any failure of ACF and Federal-Mogul to make ongoing pension contributions or to pay the unfunded liabilities upon a termination of the pension plans of ACF and Federal-Mogul. In addition, other entities now or in the future within the controlled group in which we are included may have pension plan obligations that are, or may become, underfunded and we would be liable for any failure of such entities to make ongoing pension contributions or to pay the unfunded liabilities upon termination of such plans. The current underfunded status of the pension plans of ACF and Federal-Mogul requires them to notify the PBGC of certain “reportable events,” such as if we cease to be a member of the ACF and Federal-Mogul controlled group, or if we make certain extraordinary dividends or stock redemptions. The obligation to report could cause us to seek to delay or reconsider the occurrence of such reportable events. Starfire Holding Corporation ("Starfire") which is 99.4% owned by Mr. Icahn, has undertaken to indemnify us and our subsidiaries from losses resulting from any imposition of certain pension funding or termination liabilities that may be imposed on us and our subsidiaries or our assets as a result of being a member of the Icahn controlled group. The Starfire indemnity (which does not extend to pension liabilities of our subsidiaries that would be imposed on us as a result of our interest in these subsidiaries and not as a result of Mr. Icahn and his affiliates holding more than an 80% ownership interest in us, and as such would not extend to the unfunded pension termination liability for Federal-Mogul) provides, among other things, that so long as such contingent liabilities exist and could be imposed on us, Starfire will not make any distributions to its stockholders that would reduce its net worth to below $250 million . Nonetheless, Starfire may not be able to fund its indemnification obligations to us.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events . Icahn Enterprises Distribution On April 29, 2016 , the Board of Directors of the general partner of Icahn Enterprises declared a quarterly distribution in the amount of $1.50 per depositary unit. The quarterly distribution is payable in either cash or additional depositary units, at the election of each depositary unit holder and will be paid on or about June 16, 2016 to depositary unit holders of record at the close of business on May 12, 2016 . Depositary unit holders have until June 6, 2016 to make an election to receive either cash or additional depositary units; if a holder does not make an election, it will automatically be deemed to have elected to receive the dividend in cash. Depositary unit holders who elect to receive additional depositary units will receive units valued at the volume weighted average trading price of the units on NASDAQ during the 5 consecutive trading days ending June 13, 2016 . No fractional depositary units will be issued pursuant to the dividend payment. Icahn Enterprises will make a cash payment in lieu of issuing fractional depositary units to any holders electing to receive depositary units. Any holders that would only be eligible to receive a fraction of a depositary unit based on the above calculation will receive a cash payment. Energy As further discussed in Note 2 , " Operating Units - Energy" on April 1, 2016, CVR Partners completed its previously announced merger with East Dubuque and East Dubuque GP.

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 March 31, 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 March 31, 2016 was approximately $12.5 billion and $12.1 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 $564 million and $966 million as of March 31, 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. 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 this 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 March 2016, the FASB issued ASU No. 2016-08, Principal versus agent considerations (reporting revenue gross versus net), which amends FASB ASC Topic 606, Revenue from Contracts with Customers. This ASU clarifies the implementation guidance on principal versus agent considerations, including providing guidance on indicators to assist in the evaluation as to whether an entity controls a specified good or service before it is transferred to the customers. The amendments in this ASU is effective the same time that FASB ASU No. 2014-09 becomes effective. 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: March 31, 2016 December 31, 2015 (in millions) Cash and cash equivalents $ 198 $ 237 Property, plant and equipment, net 2,667 2,674 Inventories 259 290 Goodwill — 574 Intangible assets, net 332 337 Other assets 78 102 Accounts payable, accrued expenses and other liabilities 335 333 Debt 668 667 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.

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 March 31, 2016 .

(2) The short notional amount on certain of our interest rate contracts with a three month duration is approximately $16.0 billion as of December 31, 2015.
