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, 2015. 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 108,810,845, or approximately 88.4%, of Icahn Enterprises' outstanding depositary units as of March 31, 2015.
	We are a diversified holding company owning subsidiaries currently engaged in the following continuing operating businesses: Investment, Automotive, Energy, Metals, Railcar, Gaming, 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 continuing reportable 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, 2014. 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
	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 those entities in which we have a controlling interest as a general partner interest. In evaluating whether we have a controlling financial interest in entities that we consolidate, we consider the following: (1) for voting interest entities, we consolidate these entities in which we own a majority of the voting interests; and (2) for limited partnership entities, we consolidate these entities if we are the general partner of such entities and for which no substantive kick-out rights (the rights underlying the limited partners' ability to dissolve the limited partnership or otherwise remove the general partners are collectively referred to as “kick-out” rights) or participating rights exist. 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
	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 maturities. The carrying value and estimated fair value of our long-term debt as of March 31, 2015 was approximately $12.1 billion and $12.3 billion, respectively. The carrying value and estimated fair value of our long-term debt as of December 31, 2014 was each approximately $11.6 billion.
	Restricted Cash
	Our restricted cash balance was approximately $2.0 billion and $1.3 billion as of March 31, 2015 and December 31, 2014, respectively.
	Adoption of New Accounting Standards
	In April 2014, the FASB issued ASU No. 2014-08, which amends FASB ASC Topic 205, Presentation of Financial Statements and FASB ASC Topic 360, Property, Plant, and Equipment. This ASU is effective on a prospective basis applicable to activities that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years, and changes the requirements for reporting discontinued operations. We adopted ASU No. 2014-08 during the first quarter of 2015 and believe that this guidance will reduce the number of dispositions that would qualify for discontinued operations at our parent company level, thereby reducing the complexity associated with the reporting and disclosure requirements of discontinued operations that would have been otherwise required previously.
	In November 2014, the FASB issued ASU No. 2014-17, which amends FASB Topic 805, Business Combinations. This ASU provides an acquired entity with an option to apply pushdown accounting in its separate financial statements upon the occurrence of an event in which an acquirer obtains control of the acquired entity. The ASU became effective on November 18, 2014. The adoption of this guidance during the fourth quarter of 2014 did not have any effect on our consolidated financial position, results of operations, comprehensive income, cash flows and disclosures.
	In January 2015, the FASB issued ASU No. 2015-01, which amends FASB ASU Topic 220-20, Income Statement - Extraordinary and Unusual Items. This ASU eliminates from GAAP the concept of extraordinary items. Although the ASU will eliminate the requirements in Subtopic 225-20 for reporting entities to consider whether an underlying event or transaction is extraordinary, the presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be expanded to include items that are both unusual in nature and infrequently occurring. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. A reporting entity may apply the amendments prospectively. A reporting entity also may apply the amendments retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We adopted ASU No. 2015-01 during the first quarter of 2015 and believe that the adoption of this guidance will have no impact on our 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 is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2016, using one of two retrospective application methods. Early adoption is not 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 June 2014, the FASB issued ASU No. 2014-12, which amends FASB Topic 718, Compensation-Stock Compensation. This ASU requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in FASB ASC Topic 718 as it relates to awards with performance conditions that affect vesting to account for such awards. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. This ASU is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2015. We believe that the adoption of this guidance will not have a material impact on our consolidated financial position, results of operations, comprehensive income, cash flows and disclosures.
	In February 2015, the FASB issued ASU No. 2015-02, which amends FASB ASU 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. We are currently evaluating the standard and the impact on our consolidated financial statements and footnote disclosures.
	In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, which amends FASB ASU 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. The standard is effective for interim and annual periods beginning after December 31, 2015 and is required to be applied on a retrospective basis. Early adoption is permitted. We expect that the adoption of this new guidance will result in a reclassification of debt issuance costs on our consolidated balance sheets.
	In April 2015, the FASB issued ASU No. 2015-04, Compensation-Retirement Benefits: Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Assets, which amends FAB ASU Topic 715, Compensation - Retirement Benefits. This ASU provides a practical expedient that permits the entity to measure defined benefit plan assets and obligations using the month-end that is closest to the entity’s fiscal year-end and apply that practical expedient consistently from year to year. This ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015 with early adoption 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.

	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. 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 $4.5 billion and $4.3 billion as of March 31, 2015 and December 31, 2014, respectively.
	Automotive
	We conduct our Automotive segment through our majority ownership in Federal-Mogul. 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 business segments. 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. This organizational model allows for a strong product line focus benefitting both original equipment and aftermarket customers and enables the global Federal-Mogul teams to be responsive to customers’ needs for superior products and to promote greater identification with Federal-Mogul premium brands. Additionally, this organizational model enhances management focus to capitalize on opportunities for organic and acquisition growth, profit improvement, resource utilization and business model optimization in line with the unique requirements of the two different customer bases.
	Reorganization
	On September 3, 2014, Federal-Mogul announced its plan to separate its Powertrain and Motorparts businesses into two independent, publicly-traded companies serving the global original equipment and aftermarket industries. The planned separation will be implemented through a tax-free distribution of Federal-Mogul’s Motorparts business to shareholders of Federal-Mogul Holdings Corporation. Completion of the transaction is subject to customary conditions, including among others, Federal-Mogul’s receipt of an IRS ruling or opinion of counsel to the effect that the distribution will qualify as a transaction that is generally tax-free for U.S. Federal Income tax purposes, as well as effectiveness of a Form 10 Registration Statement to be filed with the SEC.
	On February 24, 2015, Federal-Mogul announced that it would defer the previously announced spin-off of its Motorparts business to allow for the integration of its recently completed brake component, chassis and valvetrain acquisitions and to recognize the benefits of the strategic initiatives in the Motorparts business. As a result of the deferral and the recent closing of the acquisition of TRW's (as defined below) valvetrain business, Federal-Mogul commenced a common stock rights offering to strengthen its balance sheet. See below for further information regarding this rights offering. Federal-Mogul's board of directors intends to revisit the timing of the spin-off prior to the end of December 31, 2015. Meanwhile Federal-Mogul will continue to operate as two separate, independent businesses. No assurances can be given regarding the ultimate timing of the separation or that it will be consummated.
	Acquisition
	On February 6, 2015, certain subsidiaries of Federal-Mogul finalized an agreement with TRW Automotive Holdings Corp. ("TRW") to purchase certain business assets of the TRW engine components business. The business was acquired through a combination of asset and stock purchases for a base purchase price of $313 million with $6 million of consideration to be payable upon certain conditions being met. The purchase price was funded primarily from the Federal-Mogul Replacement Revolving Facility (as defined herein) and is subject to certain customary closing and post-closing adjustments. The purchase of TRW’s engine valve business adds a new product line to Federal-Mogul's portfolio, strengthens its position as a leading developer and supplier of core components for engines, and enhances its ability to support its customers to improve fuel economy and reduce emissions.
	A preliminary valuation of the net assets of the TRW engine components business acquisition resulted in $199 million allocated to tangible net assets, $51 million to goodwill and $69 million to other identified intangible assets as of the acquisition date. Because our Automotive segment is in the process of finalizing certain customary post-closing adjustments, the provisional measurements of net assets are subject to change. The valuation of net assets was performed utilizing cost, income and market approaches. The TRW engine components business acquisition is not material to our condensed consolidated financial statements.
	Agreement to Acquire Uni-Select, Inc.
	As previously disclosed, on February 9, 2015, Icahn Enterprises entered into a definitive agreement to acquire substantially all of the auto parts assets in the United States of Uni-Select, Inc. ("Uni-Select USA"), a leading automotive parts distributor for domestic and imported vehicles, for a purchase price of $340 million, subject to customary closing conditions. The acquisition of Uni-Select USA is currently expected to close during the second quarter of 2015.
	Uni-Select USA has 39 distribution centers and satellite locations and 240 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, Uni-Select USA has built its reputation on being the partner of choice for independent entrepreneurs eager to tap into the strength of large network.
	Uni-Select USA will be operated independently of Federal-Mogul and will be reported as part of our Automotive segment.
	Rights Offering
	On March 26, 2015, Federal-Mogul received $250 million in connection with its previously announced common stock registered rights offering (the “Federal-Mogul Rights Offering”). In connection with the Federal-Mogul Rights Offering, we fully exercised our subscription rights under our basic and over subscription privileges to purchase additional shares of Federal-Mogul common stock, thereby increasing our ownership of Federal-Mogul, for an aggregate additional investment of $230 million.
	As of March 31, 2015, we owned approximately 82.0% of the total outstanding common stock of Federal-Mogul.
	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 $326 million and $306 million as of March 31, 2015 and December 31, 2014, respectively. Of those gross amounts, $308 million and $293 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, 2015 and December 31, 2014, Federal-Mogul had withdrawn cash related to such transferred receivables of $2 million and $2 million, respectively. Proceeds from the transfers of accounts receivable qualifying as sales were $390 million and $410 million for the three months ended March 31, 2015 and 2014, respectively.
	For the three months ended March 31, 2015 and 2014, expenses associated with transfers of receivables were $2 million and $2 million, respectively. Such expenses were recorded in the condensed consolidated statements of operations within other (loss) income, 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 $19 million and $17 million as of March 31, 2015 and December 31, 2014, respectively. Based on Federal-Mogul's analysis of the creditworthiness of its customers on which such receivables were sold and outstanding as of both March 31, 2015 and December 31, 2014, Federal-Mogul estimated the loss to be immaterial.
	Restructuring
	During the three months ended March 31, 2015 and 2014, Federal-Mogul recorded $12 million and $8 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 has approved and initiated restructuring activities as a part of a broader initiative to improve operating performance and reduce costs. The total expected cost for the certain restructuring programs that commenced in the first quarter of 2013 and have continued through the first quarter of 2015 is $142 million, of which $133 million pertains to employee costs and $9 million pertains to facility closure and other exit costs. In connection with these restructuring programs, Federal-Mogul recorded $10 million and $4 million in charges for the three months ended March 31, 2015 and 2014, respectively, substantially all of which pertain to employee costs, with an estimated future additional restructuring cost of $11 million, all of which pertain to employee costs.

	Railcar
	Agreements with ACF Industries LLC
	In January 2013, ARI entered into a purchasing and engineering services agreement and license with ACF Industries LLC ("ACF"), an affiliate of Mr. Icahn. ACF is a leader in the manufacture and fabrication of specialty railcar parts and miscellaneous steel products. 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 August 2014, ARI and ACF amended this agreement to, among other provisions, extend the termination date to December 31, 2015 from December 31, 2014, 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 $2 million and $6 million for the three months ended March 31, 2015 and 2014, 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 a total of 1,050 railcars from ACF in 2013 and 2014 for an aggregate purchase price of approximately $150 million. Additionally, AEP Leasing had an option to purchase an additional 500 railcars for an aggregate purchase price of approximately $70 million. During the second quarter of 2014, AEP Leasing exercised its option to purchase an additional 296 railcars for an aggregate purchase price of $42 million.
	The ACF Agreement was assumed by ARL in connection with our purchase of a 75.0% 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 and $28 million for the three months ended March 31, 2015 and 2014, respectively.
	In addition to the above purchases, on a contract-by-contract basis, ARL purchased $5 million of railcars from ACF for the three months ended March 31, 2015.
	Insight Portfolio Group LLC
	Icahn Sourcing, LLC ("Icahn Sourcing") 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. Icahn Enterprises was a member of the buying group in 2012. Prior to December 31, 2012 Icahn Enterprises did not pay Icahn Sourcing any fees or other amounts with respect to the buying group arrangement.
	In December 2012, Icahn Sourcing advised Icahn Enterprises that effective January 1, 2013 it would restructure its ownership and change its name to Insight Portfolio Group LLC (“Insight Portfolio Group”). In connection with the restructuring, 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, Tropicana, ARI, ARL, Viskase, PSC Metals 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 March 31, 2015 and 2014, immaterial amounts were paid in respect to certain of the Insight Portfolio Group's operating expenses.

	Investment
	Investments, and securities sold, not yet purchased consist of equities, bonds, bank debt and other corporate obligations, and derivatives, all of which are reported at fair value in our condensed consolidated balance sheets. See Note 5, "Fair Value Measurements - Investment," for details of the investments for our Investment segment.
	Our Investment segment assesses the applicability of equity method accounting with respect to their investments based on a combination of qualitative and quantitative factors, including overall stock ownership of the Investment Funds combined with those of our affiliates along with board of directors representation.
	Our Investment segment applied the fair value option to certain of its investments that would have otherwise been subject to the equity method of accounting. As of both March 31, 2015 and December 31, 2014, the fair value of these investments was less than $1 million. During the three months ended March 31, 2015 and 2014, our Investment segment recorded (losses) gains of $(1) million and $1 million, respectively, associated with these investments. Such amounts are included in net gain (loss) from investment activities in our condensed consolidated statements of operations.
	The portion of trading gains that relates to trading securities still held by our Investment segment for the three months ended March 31, 2015 and 2014 was $509 million and $162 million, respectively.
	We believe that these investments to which we applied the fair value option are not material, individually or in the aggregate, to our condensed consolidated financial statements.
	Other Segments
	The carrying value of investments held by our Automotive, Energy, Railcar, Gaming and Home Fashion segments and our Holding Company consist of the following:


		March 31, 2015		31-Dec-14
		(in millions)
	Equity method investments	$	287	$	298

	Other investments	189		241

		$	476	$	539

	Our Holding Company applies the fair value option to its investments that would otherwise be subject to the equity method of accounting. We record unrealized gains and losses for the change in fair value of such investments as a component of net gain (loss) from investment activities in the condensed consolidated statements of operations.
	During the three months ended March 31, 2015, our Energy segment received proceeds of $42 million for the sale of a portion of its investment in available-for-sale securities. Additionally, as of March 31, 2015, our Energy segment recorded a receivable of $26 million for additional sales of its available-for-sale securities, which is included in other assets on the condensed consolidated balance sheets. The aggregate cost basis for the available-for-sale securities sold was $48 million. Upon the sale of the available-for-sale securities, our Energy segment reclassified an unrealized gain of $20 million from accumulated other comprehensive loss and recognized a realized gain in net gain (loss) from investment activities in the condensed consolidated statements of operations for the three months ended March 31, 2015. As of March 31, 2015, Our Energy segment's remaining available-for-sale securities, with an aggregate cost basis of $26 million, were reclassified to trading securities based on our Energy segment's ability and intent with respect to the securities. In connection with the transfer to trading securities, an unrealized gain of $12 million previously recorded in accumulated other comprehensive loss was reclassified to net gain (loss) from investment activities in the condensed consolidated statements of operations.

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.

Unrealized gains of less than $1 million and losses of less than $1 million are included in earnings related to Level 3 investments still held at March 31, 2015 and 2014, respectively, by our Investment segment. Total realized and unrealized gains and losses recorded for Level 3 investments are reported in net gain (loss) from investment activities in our condensed consolidated statements of operations.
The Investment Funds held one Level 3 corporate debt investment at March 31, 2015. In prior periods, in determining the fair value of this investment, we performed a yield analysis of comparable loans to which we applied a risk premium. As a result of the underlying company’s performance and bankruptcy filing in the third quarter of 2014, however, we determined that it was more appropriate to measure the fair value of our debt investment through an enterprise value analysis.

Unrealized losses of $14 million are included in earnings related to Level 3 investments still held at both March 31, 2015 and 2014 by our Gaming segment and Holding Company. Total realized and unrealized gains and losses recorded for Level 3 investments are reported in net gain (loss) from investment activities in our condensed consolidated statements of operations.
Our Gaming segment has certain debt securities that are classified as held-to-maturity since our Gaming segment has the ability and intent to hold these bonds to maturity. These debt securities are initially recorded at a discount to approximate fair value. After the initial determination of fair value, our Gaming segment analyzes recoverability of these bonds on a quarterly basis and record changes in fair value based on its historical collection experience and certain other information.
On June 30, 2014, the Investment Funds made a distribution-in-kind of a certain Level 3 corporate debt investment in the amount of $110 million to the Holding Company. In prior periods, in determining the fair value of this investment, we performed a yield analysis of comparable loans to which we applied a risk premium. As a result of the underlying company’s performance and bankruptcy filing in the third quarter of 2014, however, we determined that it was more appropriate to measure the fair value of our debt investment through an enterprise value analysis. In addition, as of March 31, 2015, the Holding Company held a certain security which lacked observable market data due to limited market activity for that security, and accordingly, was valued based on the terms of a certain tender offer. See Note 18, "Subsequent Events - Metals," for further discussion.

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, 2015, the maximum payout amounts relating to certain put options written by the Investment Funds were approximately $6.5 billion, of which approximately $6.5 billion related to covered put options on existing short positions on certain stock and credit indices. At December 31, 2014, the maximum payout amounts relating to certain put options written by the Investment Funds were approximately $2.5 billion, of which approximately $2.4 billion related to covered put options on existing short positions on certain stock and credit indices. As of March 31, 2015 and December 31, 2014, there were unrealized gains (losses) of $41 million and less than $(1) 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, 2015 and December 31, 2014 was $840 million and $614 million, respectively.
	At March 31, 2015 and December 31, 2014, the Investment Funds had approximately $1.8 billion and $1.2 billion, 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 natural gas, 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 $34 million and $36 million at March 31, 2015 and December 31, 2014, 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. Unrealized net losses of zero and $1 million were recorded in accumulated other comprehensive loss as of March 31, 2015 and December 31, 2014, 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, 2015 or December 31, 2014.
	Concentrations of Credit Risk
	Financial instruments, which potentially subject Federal-Mogul to concentrations of credit risk, consist primarily of accounts receivable and cash investments. Federal-Mogul's customer base includes virtually every significant global light and commercial vehicle manufacturer and a large number of distributors, installers and retailers of automotive aftermarket parts. Federal-Mogul's credit evaluation process and the geographical dispersion of sales transactions help to mitigate credit risk concentration. No individual customer accounted for more than 6% of Federal-Mogul's direct sales during the three months ended March 31, 2015. Federal-Mogul had one Motorparts customers that accounted for 11% of its net accounts receivable balance as of March 31, 2015. Federal-Mogul requires placement of cash in financial institutions evaluated as highly creditworthy.
	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 (loss) income, 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. As of March 31, 2015 and December 31, 2014, CVR had open commodity hedging instruments consisting of 15.0 million and 9.1 million barrels of crack spreads, respectively, primarily to fix the margin on a portion of its future gasoline and distillate production. The fair value of the outstanding contracts at March 31, 2015 and December 31, 2014 was a net asset of $2 million and $47 million, respectively. For the three months ended March 31, 2015 and 2014, CVR recognized a net loss of $50 million and a net gain of $110 million, respectively, which is included in other (loss) income, net in the condensed consolidated statements of operations.
	Interest Rate Swaps
	Coffeyville Resources Nitrogen Fertilizers, LLC ("CRNF") has 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 expires on February 12, 2016. Under the terms of the interest rate swap agreement entered into on June 30, 2011, CRNF receives a floating rate based on three-month LIBOR and pays a fixed rate of 1.940%. Under the terms of the interest rate swap agreement entered into on July 1, 2011, CRNF receives a floating rate based on three-month LIBOR and pays a fixed rate of 1.975%. Both swap agreements are settled every 90 days. The effect of these swap agreements is to lock in a fixed rate of interest of approximately 1.960% plus the applicable margin paid to lenders over three-month LIBOR as governed by the CRNF credit facility. As of both March 31, 2015 and December 31, 2014, the effective rate was approximately 4.6%. The agreements were designated as cash flow hedges at inception and accordingly, the effective portion of the gain or loss on the swap is reported as a component of accumulated other comprehensive income (loss) and will be reclassified into interest expense when the interest rate swap transaction affects earnings. The ineffective portion of the gain or loss will be recognized immediately in interest expense in the condensed consolidated statements of operations. 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, 2015 and 2014.
	Consolidated Derivative Information
	At March 31, 2015 and December 31, 2014, the volume of our derivative activities based on their notional exposure, categorized by primary underlying risk, is as follows:


		March 31, 2015						31-Dec-14
		Long Notional Exposure			Short Notional Exposure			Long Notional Exposure			Short Notional Exposure
	Primary underlying risk:	(in millions)
	Credit swaps(1)	$	311		$	1,738		$	389		$	1,493

	Equity swaps	1			13,113			1			11,312

	Interest rate swap contracts(2)	—			137			—			137

	Commodity contracts	42			749			36			234


	-1	The short notional amount on our credit default swap positions is approximately $10.9 billion and $9.3 billion as of March 31, 2015 and December 31, 2014, respectively. However, because credit spreads cannot compress below zero, our downside short notional exposure to loss is approximately $1.7 billion and $1.5 billion as of March 31, 2015 and December 31, 2014, respectively.

	-2	The short notional amount on certain of our interest rate contracts with a three month duration is approximately $16.0 billion as of both March 31, 2015 and December 31, 2014. We assume that interest rates will not fall below zero and therefore our downside short notional exposure to loss on these contracts is $74 million (of the total $137 million disclosed in the above table) as of both March 31, 2015 and December 31, 2014.

	The following table presents the consolidated fair values of our derivatives that are not designated as hedging instruments:

	Amortization expense associated with definite-lived intangible assets for the three months ended March 31, 2015 and 2014 was $22 million and $20 million, respectively. We utilize the straight-line method of amortization, recognized over the estimated useful lives of the assets.
	Automotive
	As further discussed in Note 2, "Operating Units - Automotive," during the first quarter of 2015, our Automotive segment consummated the acquisition of the TRW engine components business, recording $51 million of goodwill, $52 million of customer relationships and $17 million of developed technology as of the acquisition date. Because our Automotive segment is in the process of finalizing certain customary post-closing adjustments, the provisional measurements of net assets are subject to change. The valuation of net assets was performed utilizing cost, income and market approaches. The TRW engine components business acquisition is not material to our condensed consolidated financial statements.
	Energy
	We perform our annual goodwill impairment analysis as of April 30 of each year for our Energy segment, or more frequently if impairment indicators exist. The first step of the impairment analysis involves comparing the fair values of these assets to the respective carrying values to determine the potential for goodwill impairment. The second step of the impairment test, if necessary, involves quantifying the level of goodwill impairment.
	The fair values of our Energy segment's reporting units are based upon consideration of various valuation methodologies, including a discounted cash flow analysis ("DCF") and pricing multiples of current and future earnings observed for comparable public companies. 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 used in a DCF, which are intended to reflect the risks inherent in future cash flow projections, are based on estimates of the weighted-average cost of capital (“WACC”) 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.
	During the fourth quarter of 2014, based on certain negative trends occurring in the energy markets, particularly with respect to the significant volatility in the oil markets as a result of a drop in forecasted worldwide demand for crude oil supply and inventories, we determined that goodwill impairment indicators existed in both of our Energy segment's Petroleum and Fertilizer reporting units. Accordingly, we performed a "Step 1" goodwill impairment analysis for our Energy segment's reporting units as of December 1, 2014. Our Energy segment’s petroleum reporting unit passed “Step 1” of the goodwill impairment analysis, and therefore, we did not perform “Step 2” of the goodwill impairment analysis for this reporting unit. Because our Energy segment's Fertilizer reporting unit failed "Step 1" of the goodwill impairment analysis, we therefore, performed "Step 2" of the goodwill impairment analysis. Based on "Step 2" results of the goodwill impairment analysis, we recognized a preliminary impairment charge of $103 million for our Energy segment's Fertilizer reporting unit for the year ended December 31, 2014. Due to the complexity inherent in the "Step 2" goodwill impairment test, we finalized the assessment of our Energy segment's goodwill impairment during the first quarter of 2015 and noted that no additional adjustments to goodwill were required for the first quarter of 2015.
	Railcar
	We perform the annual goodwill impairment test as of March 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.

5.875% Senior Unsecured Notes Due 2022

On January 29, 2014, we and Icahn Enterprises Finance Corp. (“Icahn Enterprises Finance”) (collectively, the “Issuers”) issued $1.350 billion in aggregate principal amount of 5.875% Senior Notes due 2022 (the “2022 Notes”) pursuant to the purchase agreement, dated January 22, 2014 (the “2022 Notes Purchase Agreement”), by and among the Issuers, Icahn Enterprises Holdings, as guarantor, and Jefferies LLC, as initial purchaser (the “2022 Notes Purchaser”). The net proceeds from the sale of the 2022 Notes were approximately $1.340 billion after deducting the initial purchaser’s discount and commission and estimated fees and expenses related to the offering. Interest on the 2022 Notes are payable on February 1 and August 1 of each year, commencing August 1, 2014. The 2022 Notes Purchase Agreement contains customary representations, warranties and covenants of the parties and indemnification and contribution provisions whereby the Issuers and the Guarantor, on the one hand, and the 2022 Notes Purchaser, on the other, have agreed to indemnify each other against certain liabilities.

The Issuers issued the 2022 Notes under the indenture dated as of January 29, 2014 (the “2022 Indenture”), among the Issuers, Icahn Enterprises Holdings, as guarantor (the “Guarantor”), and Wilmington Trust Company, as trustee. The 2022 Indenture contains customary events of defaults and covenants relating to, among other things, the incurrence of debt, affiliate transactions, liens and restricted payments. Prior to the maturity of the 2022 Notes, the Issuers may redeem some or all of the 2022 Notes at certain times by paying a premium as specified in the 2022 Indenture, plus accrued and unpaid interest.

The 2022 Notes and the related guarantee are the senior unsecured obligations of the Issuers and rank equally with all of the Issuers’ and the Guarantor’s existing and future senior unsecured indebtedness and senior to all of the Issuers’ and the Guarantor’s existing and future subordinated indebtedness. The 2022 Notes and the related guarantee are effectively subordinated to the Issuers’ and the Guarantor’s existing and future secured indebtedness to the extent of the collateral securing such indebtedness. The 2022 Notes and the related guarantee are also effectively subordinated to all indebtedness and other liabilities of the Issuers’ subsidiaries other than the Guarantor.

In connection with the sale of the 2022 Notes, the Issuers and the Guarantor entered into a certain registration rights agreement dated January 29, 2014. See below for further discussion of this registration rights agreement.

6.00% Senior Unsecured Notes Due 2020

On August 1, 2013, the Issuers issued $500 million aggregate principal amount of 6% Senior Notes due 2020 (the “Initial 2020 Notes”) pursuant to the purchase agreement, dated July 29, 2013, by and among the Issuers, the Guarantor, and Jefferies & Company, Inc., as initial purchaser. In addition, as described below, on January 21, 2014, the Issuers issued $1.200 billion in aggregate principal amount of 6% Senior Notes due 2020 (the "Additional 2020 Notes" and together with the Initial 2020 Notes, the "2020 Notes") pursuant to the purchase agreement, dated January 8, 2014, by and among the Issuers, the Guarantor, and Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, Morgan Stanley & Co. LLC, Jefferies LLC and UBS Securities LLC, as initial purchasers. The net proceeds from the sale of the Initial 2020 Notes and the Additional 2020 Notes were $493 million and approximately $1.217 billion, respectively, after deducting the initial purchasers' discount and commission and estimated fees and expenses related to the offerings. The Additional 2020 Notes constitute the same series of securities of the 2020 Notes for purposes of the indenture governing the notes and vote together on all matters with such series. The Additional 2020 Notes have substantially identical terms as the Initial 2020 Notes. Interest on the 2020 Notes is payable on February 1 and August 1 of each year, commencing February 1, 2014.

The 2020 Notes were issued under and are governed by an indenture, dated August 1, 2013 (the “2020 Indenture”), among the Issuers, the Guarantor and Wilmington Trust Company, as trustee. The 2020 Indenture contains customary events of defaults and covenants relating to, among other things, the incurrence of debt, affiliate transactions, liens and restricted payments. Prior to the maturity of the 2020 Notes, the Issuers may redeem some or all of the 2020 Notes at certain times by paying certain premiums as specified in the 2020 Indenture, plus accrued and unpaid interest.

The 2020 Notes and the related guarantee are the senior unsecured obligations of the Issuers and the Guarantor and rank equally with all of the Issuers' and the Guarantor's existing and future senior unsecured indebtedness and rank senior to all of the Issuers' and the Guarantor's existing and future subordinated indebtedness. The series of notes constituting the 2020 Notes and the related guarantee are effectively subordinated to the Issuers' and the Guarantor's existing and future secured indebtedness to the extent of the collateral securing such indebtedness. The series of notes constituting the 2020 Notes and the related guarantee are also effectively subordinated to all indebtedness and other liabilities of the Issuers' subsidiaries other than the Guarantor.

In connection with the issuance of the Initial 2020 Notes on August 1, 2013, the Issuers and the Guarantor entered into a registration rights agreement dated August 1, 2013. On September 26, 2013, we filed an initial registration statement on Form S-4 with respect to the Initial 2020 Notes for the sole purpose of exchanging the unregistered Initial 2020 Notes for notes that are registered with the SEC ("Exchange Notes"). The exchange offer registration statement on Form S-4 with respect to the Initial 2020 Notes was declared effective on December 9, 2013. Pursuant to the registration rights agreement dated August 1, 2013, we subsequently commenced the exchange offer to exchange the Initial 2020 Notes for Exchange Notes, which exchange offer expired on January 15, 2014. All of the Initial 2020 Notes were properly tendered in the exchange offer and accepted by us in exchange for the Exchange Notes.

In connection with the sale of the Additional 2020 Notes, the Issuers and the Guarantor entered into a certain registration rights agreement dated January 29, 2014. See below for further discussion of this registration rights agreement.

4.875% Senior Unsecured Notes Due 2019 and 3.50% Senior Notes due 2017

On January 21, 2014, the Issuers issued $1.275 billion in aggregate principal amount of our 4.875% Senior Notes due 2019 (the “2019 Notes”) and $1.175 billion in aggregate principal amount of our 3.500% Senior Notes due 2017 (the “2017 Notes”) pursuant to the purchase agreement, dated January 8, 2014, by and among the Issuers, the Guarantor, and Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, Morgan Stanley & Co. LLC, Jefferies LLC and UBS Securities LLC, as initial purchasers (the “New Notes Purchasers”). The net proceeds from the sale of the 2019 Notes and the 2017 Notes were approximately $1.269 billion and $1.169 billion, respectively, after deducting the initial purchasers' discount and commission and estimated fees and expenses related to the offering.

We used the proceeds from the issuance of the Additional 2020 Notes, the 2019 Notes, and the 2017 Notes to refinance our prior notes ("2010-2012 Notes"). As a result of this refinancing, we purchased $3,500 million aggregate principal of the 2010-2012 Notes and recognized a loss of $108 million on extinguishment of debt during the first quarter of 2014. The 2010-2012 Notes were discharged in full on February 6, 2014.

The Issuers issued the 2019 Notes and the 2017 Notes under an indenture dated as of January 21, 2014 (the “2017 and 2019 Indenture”), among the Issuers, Icahn Enterprises Holdings, as guarantor, and Wilmington Trust Company, as trustee. The 2017 and 2019 Indenture contains customary events of defaults and covenants relating to, among other things, the incurrence of debt, affiliate transactions, liens and restricted payments. Prior to the maturity of the 2017 or 2019 Notes, the Issuers may redeem either the 2017 or 2019 Notes by paying certain premiums as specified in the applicable 2017 or 2022 Indenture, plus accrued and unpaid interest as applicable.

In connection with the sale of the Additional 2020 Notes, the 2019 Notes and the 2017 Notes (collectively, the "New Notes") and the 2022 Notes, the Issuers and the Guarantor entered into two registration rights agreements, one dated January 21, 2014 and the other January 29, 2014 (the “Registration Rights Agreements”), with the New Notes Purchasers and the 2022 Notes Purchaser, respectively. Pursuant to the Registration Rights Agreements, on March 28, 2014, we filed an initial Form S-4 with respect to the New Notes and 2022 Notes for the sole purpose of exchanging the unregistered New Notes and the 2022 Notes for Exchange Notes. The exchange offer registration statement on Form S-4 with respect to the New Notes and the 2022 Notes was declared effective on April 24, 2014. Pursuant to the Registration Rights Agreements, we subsequently commenced the exchange offer to exchange the New Notes and the 2022 Notes for Exchange Notes which exchange offer expired on May 23, 2014. Substantially all of the New Notes and 2022 Notes were properly tendered in the exchange offer and accepted by us in exchange for registered Exchange Notes.

Senior Unsecured Notes Restrictions and Covenants

The indentures governing both the New Notes and the 2022 Notes restrict the payment of cash distributions, the purchase of equity interests or the purchase, redemption, defeasance or acquisition of debt subordinated to the senior unsecured notes. The indentures also restrict the incurrence of debt or the issuance of disqualified stock, as defined in the indentures, with certain exceptions. In addition, the indentures require that on each quarterly determination date we and the guarantor of the notes (currently only Icahn Enterprises Holdings) maintain certain minimum financial ratios, as defined therein. The indentures also restrict the creation of liens, mergers, consolidations and sales of substantially all of our assets, and transactions with affiliates.

As of March 31, 2015 and December 31, 2014, we were in compliance with all covenants, including maintaining certain minimum financial ratios, as defined in the indentures. Additionally, as of March 31, 2015, based on covenants in the indentures governing our senior unsecured notes, we are permitted to incur approximately $792 million in additional indebtedness.

Debt Facilities - Automotive

On December 6, 2013, Federal-Mogul entered into an amendment (the “Federal-Mogul Revolver Amendment”) of its Term Loan and Revolving Credit Agreement dated as of December 27, 2007 (as amended, the “Federal-Mogul Credit Agreement”), among Federal-Mogul, the lenders party thereto, Citicorp USA, Inc., as Administrative Agent, JPMorgan Chase Bank, N.A., as Syndication Agent, and Wachovia Capital Finance Corporation and Wells Fargo Foothill, LLC, as Co-Documentation Agents, to amend its existing revolving credit facility to provide for a replacement revolving credit facility (the “Federal-Mogul Replacement Revolving Facility”). The Federal-Mogul Revolver Amendment, among other things, (i) increased the aggregate commitments available under the Federal-Mogul Replacement Revolving Facility from $540 million to $550 million, (ii) extended the maturity date of the Federal-Mogul Replacement Revolving Facility to December 6, 2018, subject to certain limited exceptions described below, and (iii) amended Federal-Mogul’s borrowing base to provide it with additional liquidity.

Advances under the Federal-Mogul Replacement Revolving Facility generally bear interest at a variable rate per annum equal to (i) the Alternate Base Rate (as defined in the Federal-Mogul Credit Agreement) plus an adjustable margin of 0.50% to 1.00% based on the average monthly availability under the Federal-Mogul Replacement Revolving Facility or (ii) Adjusted LIBOR Rate (as defined in the Federal-Mogul Credit Agreement) plus a margin of 1.50% to 2.00%based on the average monthly availability under the Federal-Mogul Replacement Revolving Facility. An unused commitment fee of 0.375% also is payable under the terms of the Federal-Mogul Replacement Revolving Facility.

Amendment to Credit Agreement

On April 15, 2014, Federal-Mogul Holdings Corporation entered into a new tranche B term loan facility (the “New Tranche B Facility”) and a new tranche C term loan facility (the “New Tranche C Facility,” and together with the New Tranche B Facility, the “New Federal-Mogul Term Facilities”), which were arranged by Citigroup Global Markets Inc. and Credit Suisse Securities (USA) LLC (the "Term Arrangers"), and assumed all of the obligations of Federal-Mogul Corporation with respect to the Federal-Mogul Replacement Revolving Facility. The New Federal-Mogul Term Facilities were entered into, and the Federal-Mogul Replacement Revolving Facility was assumed, by Federal-Mogul Holdings Corporation, pursuant to an amendment dated as of April 15, 2014 to the previously existing Term Loan and Federal-Mogul Credit Agreement dated December 27, 2007 among Federal-Mogul Corporation, the lenders party thereto (listed below), Citibank, N.A., as Revolving Administrative Agent, Citibank, N.A., as Tranche B Term Administrative Agent, Credit Suisse AG, as Tranche C Term Administrative Agent, Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC and Wells Fargo Bank, N.A., as Joint Lead Arrangers and Joint Bookrunners with respect to the Federal-Mogul Credit Agreement and Wells Fargo Bank, N.A., as sole Documentation Agent with respect to the Federal-Mogul Credit Agreement. Immediately following the closing of the New Federal-Mogul Term Facilities, Federal-Mogul Holdings Corporation contributed all of the net proceeds from the New Facilities to Federal-Mogul Corporation, and Federal-Mogul Corporation repaid its existing outstanding indebtedness as a borrower under the tranche B and tranche C term loan facilities. In connection with this debt refinancing, our Automotive segment recognized a non-cash loss on debt extinguishment of $36 million during the second quarter of 2014, which was primarily attributable to the write-off of debt discounts, and is reflected in other (loss) income, net in the condensed consolidated statements of operations.

The New Federal-Mogul Term Facilities, among other things, (i) provide for aggregate commitments under the New Tranche B Facility of $700 million with a maturity date of April 15, 2018, (ii) provide for aggregate commitments under the New Tranche C Facility of approximately $1.9 billion with a maturity date of April 15, 2021, (iii) increase the interest rates applicable to the New Federal-Mogul Facilities as described below, (iv) provide that for all outstanding letters of credit there is a corresponding decrease in borrowings available under the Federal-Mogul Replacement Revolving Facility, (v) provide that in the event that as of a particular determination date more than $700 million aggregate principal amount of existing term loans and certain related refinancing indebtedness will become due within 91 days of such determination date, the Federal-Mogul Replacement Revolving Facility will mature on such determination date, (vi) provide for additional incremental indebtedness, secured on a pari passu basis, of an unlimited amount of additional indebtedness if Federal-Mogul meets a financial covenant incurrence test, and (vii) amend certain other restrictive covenants. Pursuant to the New Federal-Mogul Term Facilities, Federal-Mogul Holdings Corporation assumed all of the obligations of Federal-Mogul Corporation with respect to the Federal-Mogul Replacement Revolving Facility.

Advances under the New Tranche B Facility generally bear interest at a variable rate per annum equal to (i) the Alternate Base Rate plus a margin of 2.00% or (ii) the Adjusted LIBOR Rate plus a margin of 3.00%, subject, in each case, to a minimum rate of 1.00%. Advances under the New Tranche C Facility generally bear interest at a variable rate per annum equal to (i) the Alternate Base Rate plus a margin of 2.75% or (ii) the Adjusted LIBOR Rate plus a margin of 3.75%, subject, in each case, to a minimum rate of 1.00% plus the applicable margin.

The obligations of Federal-Mogul under the Federal-Mogul Credit Agreement are guaranteed by substantially all of its domestic subsidiaries and certain foreign subsidiaries, and are secured by substantially all personal property and certain real property of Federal-Mogul and such guarantors, subject to certain limitations. The liens granted to secure these obligations and certain cash management and hedging obligations have first priority.

The Federal-Mogul Credit Agreement contains certain affirmative and negative covenants and events of default, including, subject to certain exceptions, restrictions on incurring additional indebtedness, mandatory prepayment provisions associated with specified asset sales and dispositions, and limitations on: i) investments; ii) certain acquisitions, mergers or consolidations; iii) sale and leaseback transactions; iv) certain transactions with affiliates; and v) dividends and other payments in respect of capital stock. At March 31, 2015 and December 31, 2014, Federal-Mogul was in compliance with all debt covenants.

As of March 31, 2015 and December 31, 2014, the borrowing availability under the Federal-Mogul Replacement Revolving Facility was $301 million and $516 million, respectively. As of March 31, 2015, the outstanding balance on the Federal-Mogul Replacement Revolving Facility was $215 million. As of December 31, 2014, there were no borrowings outstanding under the Federal-Mogul Replacement Revolving Facility. Federal-Mogul had $34 million and $34 million of letters of credit outstanding as March 31, 2015 and December 31, 2014, respectively, pertaining to Federal-Mogul's term loan credit facility. To the extent letters of credit associated with the Federal-Mogul Replacement Revolving Facility are issued, there is a corresponding decrease in borrowings available under this facility.

Senior Secured Notes

On October 23, 2012, CVR Refining LLC and its wholly owned subsidiary, Coffeyville Finance Inc., completed a private offering of $500 million in aggregate principal amount of 6.50% Senior Notes due 2022 (the "CVR 2022 Notes"). The CVR 2022 Notes were issued at par. The CVR 2022 Notes are fully and unconditionally guaranteed by CVR Refining and each of CVR Refining's existing domestic subsidiaries on a joint and several basis. The CVR 2022 Notes mature on November 1, 2022, unless earlier redeemed or repurchased by the issuers. Interest is payable on the CVR 2022 Notes semi-annually on May 1 and November 1 of each year, commencing on May 1, 2013.

The CVR 2022 Notes contain customary covenants for a financing of this type that limit, subject to certain exceptions, the incurrence of additional indebtedness or guarantees, the creation of liens on assets, the ability to dispose of assets, the ability to make certain payments on contractually subordinated debt, the ability to merge, consolidate with or into another entity and the ability to enter into certain affiliate transactions.

Amended and Restated Asset Backed (ABL) Credit Facility

CVR Refining has a senior secured asset based revolving credit facility (the "Amended and Restated ABL Credit Facility") with a group of lenders and Wells Fargo Bank, National Association (“Wells Fargo”), as administrative agent and collateral agent. The Amended and Restated ABL Credit Facility has an aggregate principal amount of up to $400 million with an incremental facility, which permits an increase in borrowings of up to $200 million subject to receipt of additional lender commitments and certain other conditions. The proceeds of the loans may be used for capital expenditures and working capital and general corporate purposes of CVR Refining and its subsidiaries. The Amended and Restated ABL Credit Facility provides for loans and letters of credit in an amount up to the aggregate availability under the facility, subject to meeting certain borrowing base conditions, with sub-limits of 10% of the total facility commitment for swingline loans and 90% of the total facility commitment for letters of credit. The Amended and Restated ABL Credit Facility is scheduled to mature on December 20, 2017.

Borrowings under the Amended and Restated ABL Credit Facility bear interest at either a base rate or LIBOR plus an applicable margin. The applicable margin is (i) (a) 1.75% for LIBOR borrowings and (b) 0.75% for prime rate borrowings, in each case if quarterly average excess availability exceeds 50% of the lesser of the borrowing base and the total commitments and (ii) (a) 2.00% for LIBOR borrowings and (b) 1.00% for prime rate borrowings, in each case if quarterly average excess availability is less than or equal to 50% of the lesser of the borrowing base and the total commitments. The Amended and Restated ABL Credit Facility also requires the payment of customary fees, including an unused line fee of (i) 0.40% if the daily average amount of loans and letters of credit outstanding is less than 50% of the lesser of the borrowing base and the total commitments and (ii) 0.30% if the daily average amount of loans and letters of credit outstanding is equal to or greater than 50% of the lesser of the borrowing base and the total commitments. CVR Refining will also be required to pay customary letter of credit fees equal to, for standby letters of credit, the applicable margin on LIBOR loans on the maximum amount available to be drawn under and, for commercial letters of credit, the applicable margin on LIBOR loans less 0.50% on the maximum amount available to be drawn under, and customary facing fees equal to 0.125% of the face amount of, each letter of credit.

The Amended and Restated ABL Credit Facility also contains customary covenants for a financing of this type that limit the ability of CVR Refining and its subsidiaries to, among other things, incur liens, engage in a consolidation, merger, purchase or sale of assets, pay dividends, incur indebtedness, make advances, investments and loans, enter into affiliate transactions, issue equity interests, or create subsidiaries and unrestricted subsidiaries. The Amended and Restated ABL Credit Facility also contains a fixed charge coverage ratio financial covenant, as defined therein.

The initial pricing for Eurodollar rate loans under the credit facility is the Eurodollar rate plus a margin of 3.50% or, for base rate loans, the prime rate plus 2.50%. Under its terms, the lenders under the credit facility were granted a first priority security interest (subject to certain customary exceptions) in substantially all of the assets of CRNF and CVR Partners.

The credit facility requires CVR Partners to maintain a minimum interest coverage ratio and a maximum leverage ratio and contains customary covenants for a financing of this type that limit, subject to certain exceptions, the incurrence of additional indebtedness or guarantees, the incurrence of liens, disposal of assets, making restricted payments, making investments or acquisitions and entry into sale-leaseback transactions or affiliate transactions. The credit facility provides that CVR Partners can make distributions to holders of its common units provided, among other things, it is in compliance with the leverage ratio and interest coverage ratio on a pro forma basis after giving effect to any distribution and there is no default or event of default under the credit facility. As of March 31, 2015, CRNF was in compliance with the covenants contained in the credit facility.

2014 Lease Fleet Financing

In January 2014, ARI, through its wholly owned subsidiary, Longtrain Leasing I, LLC ("Longtrain Leasing I") refinanced a certain term loan (the "Original ARI Term Loan") under an amended and restated credit agreement to, among other provisions, increase the aggregate borrowings available thereunder. In connection with the refinancing, Longtrain Leasing I received borrowings of $316 million, net of fees and expenses (the "ARI Refinanced Term Loan"). Of this amount, $194 million was used to refinance the Original ARI Term Loan, resulting in net proceeds of $122 million. In conjunction with the refinancing, ARI incurred a $2 million loss on extinguishment of debt, which is reflected in other (loss) income, net in our condensed consolidated statements of operations during the first quarter of 2014. As of December 31, 2014, the outstanding principal balance on the ARI Refinanced Term Loan was $309 million. In connection with the lease fleet financing as discussed below, the ARI Refinanced Term Loan was repaid in full during the first quarter of 2015.

In October 2014, ARI, through Longtrain Leasing II LLC ("Longtrain Leasing II"), a wholly owned subsidiary of ARI, entered into a lease fleet financing facility for $100 million under a term loan agreement ("Longtrain Leasing II Term Loan") in order to support the growth of its leasing business.

On January 29, 2015, ARI refinanced its lease fleet financing facilities to, among other things, increase the aggregate borrowings thereunder. In connection with the refinancing, Longtrain Leasing III LLC ("Longtrain Leasing III") completed a private placement of $626 million in aggregate principal amount of notes consisting of $250 million in aggregate principal amount of its 2.98% Fixed Rate Secured Railcar Equipment Notes, Class A-1 ("ARI Class A-1 Notes") and $376 million in aggregate principal amount of its 4.06% Fixed Rate Secured Railcar Equipment Notes, Class A-2 ("ARI Class A-2 Notes", and collectively with the ARI Class A-1 Notes, the "ARI 2015 Notes"). Of the aggregate principal amount, $409 million was used to refinance ARI's lease fleet financing facilities, resulting in net proceeds of $212 million. In conjunction with the refinancing, our Railcar segment incurred a $2 million loss on debt extinguishment, which is reflected in other (loss) income, net in the condensed consolidated statements of operations. This non-cash charge is related to the accelerated write-off of deferred debt issuance costs incurred in connection with the Longtrain Leasing I and Longtrain Leasing II lease fleet financings. As of March 31, 2015, the outstanding principal balance on the ARI 2015 Notes was $621 million. The ARI 2015 Notes have a legal final maturity date of January 17, 2045 and an expected principal repayment date of January 15, 2025.

The ARI 2015 Notes were issued pursuant to a certain indenture (the "ARI Indenture), dated January 29, 2015 between Longtrain Leasing III and U.S. Bank National Association, as indenture trustee ("ARI Indenture Trustee"). The ARI Class A-1 Notes bear interest at a fixed rate of 2.98% per annum, and the ARI Class A-2 Notes bear interest at a fixed rate of 4.06% per annum. Interest on the ARI 2015 Notes is payable monthly on the 15th calendar day of each month in accordance with the flow of funds provisions described in the ARI Indenture. While the legal final maturity date of the ARI 2015 Notes is January 17, 2045, cash flows from Longtrain Leasing III's assets will be applied, pursuant to the flow of funds provisions of the ARI Indenture, so as to achieve monthly targeted principal balances. Also, under the flow of funds provisions of the ARI Indenture, early amortization of the ARI 2015 Notes may be required in certain circumstances. If the ARI 2015 Notes are not repaid by the expected principal repayment date on January 15, 2025, additional interest shall accrue at a rate of 5.0% per annum and be payable monthly according to the flow of funds. Pursuant to the terms of the ARI Indenture, ARI is required to maintain deposits in a liquidity reserve bank account equal to nine months of interest payments. As of March 31, 2015, the liquidity reserve amount was $17 million, and included within restricted cash on the condensed consolidated balance sheets.

Longtrain Leasing III can prepay or redeem the ARI Class A-1 Notes, in whole or in part, on any payment date and the ARI Class A-2 Notes, in whole or in part, on any payment date occurring on or after January 16, 2018.

The Indenture contains covenants which limit, among other things, Longtrain Leasing III's ability to incur additional indebtedness or encumbrances on its assets, pay dividends or make distributions, make certain investments, perform its business other than specified activities, enter into certain types of transactions with its affiliates, and sell assets or consolidate or merge with or into other companies. These covenants are subject to a number of exceptions and qualifications. ARI was in compliance with all of these covenants as of March 31, 2015.

The ARI Indenture also contains certain customary events of default, including among others, failure to pay amounts when due after applicable grace periods, failure to comply with certain covenants and agreements, and certain events of bankruptcy or insolvency. Certain events of default under the ARI Indenture will make the outstanding principal balance and accrued interest on the ARI 2015 Notes, together with all amounts then due and owing to the noteholders, immediately due and payable without further action. For other events of default, the ARI Indenture Trustee, acting at the direction of a majority of the noteholders, may declare the principal of and accrued interest on all ARI 2015 Notes then outstanding to be due and payable immediately.

As of March 31, 2015 and December 31, 2014, the net book value of the railcars that were pledged as part of the lease fleet financings was $495 million and $277 million, respectively.

Net Income Per LP Unit	Net Income Per LP Unit.
	The following table sets forth the allocation of net income attributable to Icahn Enterprises allocable to limited partners and the computation of basic and diluted income per LP unit of Icahn Enterprises for the periods indicated:


		Three Months Ended March 31,
		2015		2014
		(in millions, except per unit data)
	Net income (loss) attributable to Icahn Enterprises	$	161	$	(29	)

	Net income (loss) attributable to Icahn Enterprises allocable to limited partners (98.01% allocation)	$	158	$	(28	)


	Basic income (loss) per LP unit	$	1.28	$	(0.24	)

	Basic weighted average LP units outstanding	123		117

	Income	$	—

	Units	1


	Diluted income (loss) per LP unit	$	1.27	$	(0.24	)

	Diluted weighted average LP units outstanding	124		117

	Unit Distribution
	On February 20, 2015, 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 22, 2015, Icahn Enterprises distributed an aggregate 1,713,935 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 6, 2015, Mr. Icahn and his affiliates owned 88.5% 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 $188 million on our condensed consolidated balance sheets as the unit distribution had not been made as of March 31, 2015. 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. 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.

Segment Reporting	Segment Reporting.
	As of March 31, 2015, our nine operating segments, which also constitute our reporting segments, are: (1) Investment; (2) Automotive; (3) Energy; (4) Metals; (5) Railcar; (6) Gaming; (7) Food Packaging; (8) Real Estate; and (9) Home Fashion. Our determination of what constitutes an operating segment is based on the various industries in which our businesses operate and how we manage those businesses in accordance with our investment strategy. We assess and measure segment operating results based on net income from continuing operations attributable to Icahn Enterprises and Icahn Enterprises Holdings, as disclosed below. In addition to our nine reporting segments, we present the results of the Holding Company, which includes the unconsolidated results of Icahn Enterprises and Icahn Enterprises Holdings, and investment activity and expenses associated with the activities of the Holding Company. See Note 2, “Operating Units,” for a detailed description of each of our reporting segments.
	Icahn Enterprises' condensed statements of operations by reporting segment for the three months ended March 31, 2015 and 2014 are presented below:

	For the three months ended March 31, 2015, each of Icahn Enterprises and Icahn Enterprises Holdings recorded an income tax expense of $49 million on pre-tax income of $471 million compared to an income tax expense of $103 million on pre-tax income of $180 million for the three months ended March 31, 2014. Our effective income tax rate was 10.4% and 57.2% for the three months ended March 31, 2015 and 2014, respectively.
	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.
	For the three months ended March 31, 2014, the effective tax rate was higher 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.

	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 $15 million and $15 million as of March 31, 2015 and December 31, 2014, 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, 2015, Federal-Mogul estimates reasonably possible material additional losses, above and beyond its best estimate of required remediation costs as recorded, to approximate $35 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 $19 million and $24 million as of March 31, 2015 and December 31, 2014, 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, 2015 and 2014 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"), which currently extends through December 31, 2015 under a one-year renewal term. 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.
	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, 2014. 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.
	Property Tax Matter
	As previously disclosed in our 2014 Form 10-K, CRNF received a ten-year property tax abatement from Montgomery County, Kansas (the "County") in connection with the construction of the nitrogen fertilizer plant that expired on December 31, 2007. In connection with the expiration of the abatement, the county reclassified and reassessed CRNF's nitrogen fertilizer plant for property tax purposes. CRNF protested the classification and resulting valuation. The Kansas Court of Appeals remanded the case to the Board of Tax Appeals ("BOTA"), instructing BOTA to classify each asset on an asset-by-asset basis instead of making a broad determination that the entire plant was real property as BOTA did originally. In March 2015, BOTA concluded that based upon an asset-by-asset determination a substantial majority of the assets in dispute will be classified as personal property for the 2008 tax year. CRNF and the County next will submit evidence of valuation to BOTA with respect to the real property, following which BOTA will issue its final decision. No amounts have been received or recognized in our condensed consolidated financial statements related to the 2008 property tax matter or BOTA's decision.
	Flood, Crude Oil Discharge and Insurance
	As previously disclosed in our 2014 Form 10-K, crude oil was discharged from CRRM's Coffeyville refinery on July 1, 2007, due to the short amount of time available to shut down and secure the refinery in preparation for the flood that occurred on June 30, 2007. CRRM sought insurance coverage for the crude oil release and for the ultimate costs for remediation and third-party property damage claims. On July 10, 2008, CRRM filed a lawsuit in the United States District Court for the District of Kansas against certain of its environmental insurance carriers requesting insurance coverage indemnification for the June/July 2007 flood and crude oil discharge losses. In November 2014, CRRM concluded a jury trial against the remaining insurance carriers and received a verdict and judgment of $27 million, exclusive of potential prejudgment interest and attorneys' fees. In February 2015, the Court awarded CRRM $3 million in prejudgment interest, resulting in a total amended judgment of $30 million. CRRM and the defendant insurance companies have filed notice of appeal to the United States Court of Appeals for the Tenth Circuit. CVR Refining has a $4 million receivable related to this matter as of both March 31, 2015 and December 31, 2014. In accordance with accounting guidance related to gain contingencies, no additional amounts have been recognized related to the verdict and judgment in our consolidated financial statements.
	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 2014 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 2014 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, 2015 and December 31, 2014, our Energy segment had environmental accruals of $1 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, 2015 and 2014, capital expenditures were $11 million and $34 million, respectively, and were incurred for environmental compliance and efficiency of the operations.
	The cost of RINs for three months ended March 31, 2015 and 2014 was $37 million and $35 million, respectively. As of March 31, 2015 and December 31, 2014, the petroleum business' biofuel blending obligation was $57 million and $52 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 $27 million and $28 million at March 31, 2015 and December 31, 2014, 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, 2015 and December 31, 2014. 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.
	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. However, ARI believes that Gyansys' counterclaims lack merit, and ARI has filed a motion to dismiss Gyansys' counterclaims in part.
	Home Fashion
	Environmental Matters
	WPH is subject to various federal, state and local environmental laws and regulations governing, among other things, the discharge, storage, handling and disposal of a variety of hazardous and nonhazardous substances and wastes used in or resulting from its operations and potential remediation obligations. WPH's operations are also governed by U.S. federal, state, local and foreign laws, rules and regulations relating to employee safety and health which, among other things, establish exposure limitation for cotton dust, formaldehyde, asbestos and noise, and which regulate chemical, physical and ergonomic hazards in the workplace. WPH estimated its environmental accruals to be approximately $1 million at both March 31, 2015 and December 31, 2014.
	Other Matters
	Mr. Icahn, through certain affiliates, owns 100% of Icahn Enterprises GP and approximately 88.4% of Icahn Enterprises' outstanding depositary units as of March 31, 2015. 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, 2015 and December 31, 2014. If the plans were voluntarily terminated, they would be underfunded by approximately $493 million and $474 million as of March 31, 2015 and December 31, 2014, 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.

	Icahn Enterprises
	Distribution
	On May 5, 2015, 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 30, 2015 to depositary unit holders of record at the close of business on May 19, 2015. Depositary unit holders have until June 11, 2015 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 10 consecutive trading days ending June 25, 2015. 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.
	Metals
	On April 25, 2015, IEP Ferrous Brazil LLC ("IEP Ferrous"), a wholly owned subsidiary of ours, entered into an agreement which provides that IEP Ferrous will tender for any and all of the outstanding shares of Ferrous Resources Limited ("Ferrous Resources") for total consideration of up to $230 million and backstop a certain rights offering of up to $40 million. This transaction is subject to certain terms and conditions, including the receipt of certain government and shareholder approvals. We cannot assure you that this transaction will be consummated.
	If we are able to close on the transaction, IEP Ferrous will control Ferrous Resources and its results will be reported as part of our Metals' segment. The acquisition of Ferrous Resources, if consummated, would not be material to our condensed consolidated financial statements.
	Railcar
	In April 2015, ARI entered into a repair services and support agreement with ACF. Under this agreement, ARI will provide certain sales and administrative and technical services, materials and purchasing support and engineering services to ACF to provide repair and retrofit services ("Repair Services"). Additionally, ARI will provide a non-exclusive and non-assignable license of certain intellectual property related to the Repair Services for railcars. ARI will receive 30% of the net profits (as defined in the agreement) for Repair Services related to all railcars not owned by ARL or its subsidiaries and 20% of the net profits for Repair Services related to all railcars owned by ARL or its subsidiaries, if any, but will not absorb any losses incurred by ACF. Under the agreement, ARI has the exclusive right to sales opportunities related to Repair Services, except for any sales opportunity related to Repair Services presented to ACF by ARL with respect to ARL-owned railcars. ARI also has the right to assign any sales opportunities related to Repair Services to ACF, and ACF has the right, but not the obligation, to accept such sales opportunity. Subject to certain early termination events, the agreement terminates on December 31, 2020.
	Also in April 2015, ARI entered into a parts purchasing and sale agreement with ACF. 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 will provide 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 Railcar Parts as determined in the agreement or as stated on a public website for all ARI buyers. 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Reclassifications [Policy Text Block]	Reclassifications
Reclassifications [Policy Text Block]	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
Principals of consolidation [Policy Text Block]	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 those entities in which we have a controlling interest as a general partner interest. In evaluating whether we have a controlling financial interest in entities that we consolidate, we consider the following: (1) for voting interest entities, we consolidate these entities in which we own a majority of the voting interests; and (2) for limited partnership entities, we consolidate these entities if we are the general partner of such entities and for which no substantive kick-out rights (the rights underlying the limited partners' ability to dissolve the limited partnership or otherwise remove the general partners are collectively referred to as “kick-out” rights) or participating rights exist. All material intercompany accounts and transactions have been eliminated in consolidation.
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 maturities. The carrying value and estimated fair value of our long-term debt as of March 31, 2015 was approximately $12.1 billion and $12.3 billion, respectively. The carrying value and estimated fair value of our long-term debt as of December 31, 2014 was each approximately $11.6 billion.
Restricted cash [Policy Text Block]	Restricted Cash
Restricted cash [Policy Text Block]	Our restricted cash balance was approximately $2.0 billion and $1.3 billion as of March 31, 2015 and December 31, 2014, respectively.
Adoption of new accounting pronouncements [Policy Text Block]	Adoption of New Accounting Standards
	In April 2014, the FASB issued ASU No. 2014-08, which amends FASB ASC Topic 205, Presentation of Financial Statements and FASB ASC Topic 360, Property, Plant, and Equipment. This ASU is effective on a prospective basis applicable to activities that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years, and changes the requirements for reporting discontinued operations. We adopted ASU No. 2014-08 during the first quarter of 2015 and believe that this guidance will reduce the number of dispositions that would qualify for discontinued operations at our parent company level, thereby reducing the complexity associated with the reporting and disclosure requirements of discontinued operations that would have been otherwise required previously.
	In November 2014, the FASB issued ASU No. 2014-17, which amends FASB Topic 805, Business Combinations. This ASU provides an acquired entity with an option to apply pushdown accounting in its separate financial statements upon the occurrence of an event in which an acquirer obtains control of the acquired entity. The ASU became effective on November 18, 2014. The adoption of this guidance during the fourth quarter of 2014 did not have any effect on our consolidated financial position, results of operations, comprehensive income, cash flows and disclosures.
	In January 2015, the FASB issued ASU No. 2015-01, which amends FASB ASU Topic 220-20, Income Statement - Extraordinary and Unusual Items. This ASU eliminates from GAAP the concept of extraordinary items. Although the ASU will eliminate the requirements in Subtopic 225-20 for reporting entities to consider whether an underlying event or transaction is extraordinary, the presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be expanded to include items that are both unusual in nature and infrequently occurring. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. A reporting entity may apply the amendments prospectively. A reporting entity also may apply the amendments retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We adopted ASU No. 2015-01 during the first quarter of 2015 and believe that the adoption of this guidance will have no impact on our 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 is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2016, using one of two retrospective application methods. Early adoption is not 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 June 2014, the FASB issued ASU No. 2014-12, which amends FASB Topic 718, Compensation-Stock Compensation. This ASU requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in FASB ASC Topic 718 as it relates to awards with performance conditions that affect vesting to account for such awards. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. This ASU is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2015. We believe that the adoption of this guidance will not have a material impact on our consolidated financial position, results of operations, comprehensive income, cash flows and disclosures.
	In February 2015, the FASB issued ASU No. 2015-02, which amends FASB ASU 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. We are currently evaluating the standard and the impact on our consolidated financial statements and footnote disclosures.
	In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, which amends FASB ASU 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. The standard is effective for interim and annual periods beginning after December 31, 2015 and is required to be applied on a retrospective basis. Early adoption is permitted. We expect that the adoption of this new guidance will result in a reclassification of debt issuance costs on our consolidated balance sheets.
	In April 2015, the FASB issued ASU No. 2015-04, Compensation-Retirement Benefits: Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Assets, which amends FAB ASU Topic 715, Compensation - Retirement Benefits. This ASU provides a practical expedient that permits the entity to measure defined benefit plan assets and obligations using the month-end that is closest to the entity’s fiscal year-end and apply that practical expedient consistently from year to year. This ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015 with early adoption 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.

Financial Instruments [Abstract]
Schedule of Notional Amounts of Outstanding Derivative Positions	At March 31, 2015 and December 31, 2014, the volume of our derivative activities based on their notional exposure, categorized by primary underlying risk, is as follows:


		March 31, 2015								31-Dec-14
		Long Notional Exposure				Short Notional Exposure				Long Notional Exposure				Short Notional Exposure
	Primary underlying risk:	(in millions)
	Credit swaps(1)	$	311			$	1,738			$	389			$	1,493

	Equity swaps	1				13,113				1				11,312

	Interest rate swap contracts(2)	—				137				—				137

	Commodity contracts	42				749				36				234


	-1	The short notional amount on our credit default swap positions is approximately $10.9 billion and $9.3 billion as of March 31, 2015 and December 31, 2014, respectively. However, because credit spreads cannot compress below zero, our downside short notional exposure to loss is approximately $1.7 billion and $1.5 billion as of March 31, 2015 and December 31, 2014, respectively.

	-2	The short notional amount on certain of our interest rate contracts with a three month duration is approximately $16.0 billion as of both March 31, 2015 and December 31, 2014. We assume that interest rates will not fall below zero and therefore our downside short notional exposure to loss on these contracts is $74 million (of the total $137 million disclosed in the above table) as of both March 31, 2015 and December 31, 2014.
