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 September 30, 2014. 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 107,212,654, or approximately 88.3%, of Icahn Enterprises' outstanding depositary units as of September 30, 2014. 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 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, 2013. The 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 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 The carrying values of cash and cash equivalents, cash held at consolidated affiliated partnerships and restricted cash, accounts receivable, due to brokers, accounts payable, accrued expenses and other liabilities 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 September 30, 2014 was each approximately $11.5 billion. The carrying value and estimated fair value of our long-term debt as of December 31, 2013 was approximately $9.3 billion and $9.4 billion, respectively. Restricted Cash Our restricted cash balance was approximately $1.2 billion and $330 million as of September 30, 2014 and December 31, 2013, respectively. Adoption of New Accounting Standards In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-04, which amends FASB ASC Topic 405, Liabilities. This ASU requires the measurement of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date as the sum of (1) the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and (2) any additional amount the reporting entity expects to pay on behalf of its co-obligors. This guidance also requires the disclosure of the nature and amount of the obligation as well as other information about those obligations. The guidance is effective for interim and annual periods beginning after December 15, 2013. The adoption of this guidance during the first quarter of 2014 did not have a material impact on our consolidated financial position, results of operations or cash flows. In March 2013, the FASB issued ASU No. 2013-05, which amends FASB ASC Topic 830, Foreign Currency Matters. This ASU resolves the accounting for certain foreign currency matters with respect to the release of cumulative translation adjustment into net income within a foreign entity under certain circumstances. This ASU is effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013. This ASU should be applied prospectively to derecognition events occurring after the effective date. The adoption of this guidance during the first quarter of 2014 did not have a material impact on our consolidated financial position, results of operations or cash flows. In July 2013, the FASB issued ASU No. 2013-11, which amends FASB ASC Topic 740, Income Taxes. This ASU requires that unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operation loss carryforward, a similar tax loss, or a tax credit carryforward, except in certain cases. This ASU is effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013. The adoption of this guidance during the first quarter of 2014 did not have a material impact on our consolidated financial position, results of operations or cash flows. Recently Issued 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. Early adoption is permitted, but only for disposals that have not been reported in financial statements previously issued or available for issuance. We believe that ASU No. 2014-08 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 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. We are currently evaluating the impact that the adoption of this guidance will have on our consolidated financial position, results of operations, cash flows and disclosures. In June 2014, the FASB issued ASU No. 2014-12, which amends FASB ASU 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 are currently evaluating the impact that the adoption of this guidance will have on our financial position, results of operations, comprehensive income, cash flows and/or disclosures. Filing Status of Subsidiaries Federal-Mogul Holdings Corporation (“Federal-Mogul”), CVR Energy, Inc. ("CVR"), American Railcar Industries, Inc. (“ARI”) and Tropicana Entertainment Inc. (“Tropicana”) are each a public reporting entity under the Securities Exchange Act of 1934, as amended, and file annual, quarterly and current reports and proxy and information statements with the SEC.
