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. 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 11, "Debt," and 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 101,872,909, or approximately 87.9%, of Icahn Enterprises' outstanding depositary units as of December 31, 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 4, “Operating Units,” and Note 15, “Segment and Geographic 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”). Change in Reporting Entity As discussed further in Note 3, "Acquisitions - New ARL," pursuant to a contribution agreement (the "ARL Contribution Agreement") dated September 20, 2013 and with a closing date on October 2, 2013 among AEP Rail Corp. ("AEP"), IRL Holding LLC ("IRL"), American Railcar Leasing, LLC ("ARL") and IEP Energy Holding LLC, we acquired a 75% economic interest in the newly capitalized ARL ("New ARL"). New ARL is considered an entity under common control. Accordingly, the accompanying consolidated financial statements and footnotes include the assets and operations of New ARL for all periods presented.
