Subsequent Events [Text Block]	Subsequent Events. Rights Offering On December 1, 2011, we announced our intention to launch a rights offering to raise proceeds of approximately $500 million. The purposes of the rights offering were to: (i) enhance our depositary unit holder equity; (ii) endeavor to improve our credit ratings, and (iii) raise equity capital to be used for potential investments and acquisitions. Icahn Enterprises filed a registration statement on Form S-3 with the SEC that registered the rights and the new depositary units. The registration statement was declared effective on December 27, 2011. Pursuant to the rights offering, Icahn Enterprises distributed transferable subscription rights pro rata to the holders of record of its depositary units as of the close of business on December 27, 2011, the record date. Icahn Enterprises' depositary unitholders received 0.15881 rights for each depositary unit held as of the record date. Each whole right entitled the holder to acquire one newly issued depositary unit of Icahn Enterprises at a subscription price of $36.7933. In addition, holders of rights were entitled to subscribe for additional depositary units that remained unsubscribed as a result of any unexercised subscription rights. Icahn Enterprises distributed the rights to the record date unitholders on January 3, 2012. The rights traded on the NASDAQ Global Select Market ("NASDAQ") under the ticker symbol "IEPRR" from January 3, 2012 until the close of NASDAQ on January 20, 2012, the expiration date of the rights offering. No fractional depositary units were issued in the rights offering. The number of depositary units issued upon exercise by all unitholders of its rights were rounded to the nearest whole depositary unit to eliminate fractional depositary units. In connection with this rights offering, we distributed and aggregate 13,590,238 additional depositary units to unitholders that subscribed to the basic subscription rights and the over-subscription rights and we received proceeds of $500 million. Of these additional depositary units distributed pursuant to the rights offering, Mr. Icahn and his affiliates received 12,995,584 additional depositary units, bringing their total depositary units held to 92,233,846 units, or approximately 93.0% of our total outstanding depositary units. Debt Offerings On January 17, 2012 and February 6, 2012, the Issuers issued an additional aggregate $700 million principal amount of the 2018 Notes, pursuant to their respective purchase agreements, by and among the Issuers, Icahn Enterprises Holdings, as guarantor and Jefferies & Company, Inc., as initial purchaser. These notes constitute the same series of securities as the Initial Notes for purposes of the indenture governing the notes and vote together on all matters with such series. These notes have substantially identical terms as the Initial Notes. The gross proceeds from the sale of these notes were $716 million and will be used for general corporate purposes. Refer to Note 10, "Debt," for additional information regarding our 8% Senior Unsecured Notes Due 2018. Treasury Units Subsequent to December 31, 2011, we canceled all of our treasury depositary units, or 1,137,200 treasury depositary units. Distribution On February 28, 2012, the board of directors declared a quarterly distribution of $0.35 per depositary unit, comprised of a combination of $0.10 payable in cash and $0.25 payable in depositary units. The distribution will be paid on March 30, 2012 to depositary unitholders of record at the close of business on March 15, 2012. We calculated the depositary units to be distributed based on the 20 trading day volume weighted average price of our depositary units ending on February 27, 2012, resulting in .006269 of a unit being distributed per depositary unit. To the extent that the aggregate units to be distributed to any holder would include a fraction of a unit, that fractional unit will be settled in cash. The cut-off date for brokers or nominees to advise our transfer agent, Registrar and Transfer Company, of their full and fractional unit requirements is March 22, 2012. Tender Offer On February 23, 2012, IEP Energy LLC, a wholly owned subsidiary of Icahn Enterprises Holdings, commenced an offer to purchase all of the issued and outstanding shares of common stock of CVR Energy, Inc. (“CVR”) at a price of $30.00 per share, without interest and less any required withholding taxes, if any, plus one non-transferable contingent cash payment right for each share, which represents the contractual right to receive an additional cash payment per share if a definitive agreement for the sale of CVR is executed within nine months following the expiration date of the offer and such transaction closes. In addition, on February 16, 2012, affiliates of Mr. Icahn announced their intent to nominate a slate for all 9 directorships on CVR's board of directors at the upcoming 2012 annual meeting of CVR's stockholders. ARI/ARL Management Agreement On February 29, 2012, ARI entered into a Railcar Management Agreement (the Railcar Management Agreement) with ARL, pursuant to which ARI engaged ARL to market ARI's railcars for sale or lease, subject to the terms and conditions of the Railcar Management Agreement. The Railcar Management Agreement was effective as of January 1, 2011, will continue through December 31, 2015 and may be renewed upon written agreement by both parties. The Railcar Management Agreement also provides that ARL will manage the ARI's leased railcars including arranging for services, such as repairs or maintenance, as deemed necessary. Subject to the terms and conditions of the agreement, ARL will receive, in respect of leased railcars, a fee consisting of a lease origination fee and a management fee based on the lease revenues, and, in respect of railcars sold by ARL, sales commissions. The Railcar Management Agreement was unanimously approved by ARI's and Icahn Enterprises' independent directors of audit committees on the basis that the terms of the Railcar Management Agreement were not materially less favorable than those that would have been obtained in a comparable transaction with an unaffiliated third party. Thailand Manufacturing Facility Flood In October 2011, a flood occurred at one of Federal-Mogul's manufacturing facility in Ayutthaya, Thailand. This facility was partially submerged in the flood waters for a period of approximately six weeks, resulting in extensive damage to the facility and the loss of substantially all of its related equipment and inventory. Operations at the facility are currently suspended. In addition to other coverage, Federal-Mogul believes its insurance policies provide for replacement of damaged property, sales value of destroyed inventory, reimbursement for losses due to interruption of business operations and reimbursement of expenditures incurred to restore operations. In February 2012, Federal-Mogul received a $25 million cash advance from its insurance carrier.
