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, 2013. 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 100,436,406, or approximately 89.4%, of Icahn Enterprises' outstanding depositary units as of September 30, 2013. 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, 2012. The consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“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. Purchase Price Allocation On May 4, 2012, we acquired a controlling interest in CVR Energy, Inc. ("CVR") and have allocated the total purchase price to the fair value of assets acquired and liabilities assumed based on their fair values at the acquisition date, with amounts exceeding fair values recorded as goodwill. The purchase price allocation was finalized during the second quarter of 2013. See Note 8, "Goodwill and Intangible Assets, Net - Energy," for further discussion. Principles of Consolidation Our consolidated financial statements include the accounts of (i) Icahn Enterprises and (ii) the wholly and majority owned subsidiaries of Icahn Enterprises, in addition to those entities in which we have a controlling interest as a general partner interest or in which we may be the primary beneficiary of a variable interest entity (“VIE”). In evaluating whether we have a controlling financial interest in entities that we would 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 that are not considered VIEs, 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, 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 September 30, 2013 was approximately $8.2 billion and $8.3 billion, respectively. The carrying value and estimated fair value of our long-term debt as of December 31, 2012 was approximately $8.5 billion and $8.6 billion, respectively. Restricted Cash Our restricted cash balance was approximately $1.4 billion and $0.7 billion as of September 30, 2013 and December 31, 2012, respectively. Adoption of New Accounting Standards In December 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2011-11, which amends FASB Accounting Standards Codification ("ASC") Topic 210, Balance Sheet. This ASU requires companies to disclose both gross and net information about instruments and transactions eligible for offset in the statement of financial position as well as instruments and transactions subject to an agreement similar to a master netting arrangement. In January 2013, the FASB issued ASU No. 2013-01, which further amends FASB ASC Topic 210. This ASU limits the scope of the original guidance. These ASUs are effective retrospectively for interim and annual periods beginning on or after January 1, 2013. We adopted these additional disclosure requirements effective January 1, 2013 which had minimal impact on our disclosures. In February 2013, the FASB issued ASU No. 2013-02, which amends FASB ASC Topic 220, Comprehensive Income. This ASU requires an entity to provide information about amounts reclassified out of accumulated other comprehensive income by component. The guidance is effective prospectively for interim and annual periods beginning after December 15, 2012. We adopted these additional disclosure requirements effective January 1, 2013. See Note15, "Changes in Accumulated Other Comprehensive Loss," for additional information. Recently Issued Accounting Standards In February 2013, the FASB issued 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. We anticipate that the adoption of this guidance will not have a material impact on our consolidated financial position, results of operations and 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. Early adoption is permitted provided that if the entity adopts this guidance early, it is applied as of the beginning of the entity's fiscal year of adoption. The adoption of this ASU will not have a material impact on our consolidated financial position, results of operations or cash flows. In June 2013, the FASB issued ASU No. 2013-08, which amends FASB ASC Topic 946, Financial Services - Investment Companies. This ASU clarifies the characteristics of an investment company, and provides comprehensive guidance for assessing whether an entity is an investment company. This ASU is effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013. Earlier adoption is prohibited. The adoption of this ASU will not have any 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 benefits, 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 operating 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. Earlier adoption is permitted. The adoption of this ASU will not have any impact on our consolidated financial position, results of operations or cash flows. Filing Status of Subsidiaries Federal-Mogul Corporation (“Federal-Mogul”), 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 Securities and Exchange Commission ("SEC"). Each of these reports is publicly available at www.sec.gov.
