Our amended and restated agreement of limited partnership expressly permits us to enter into transactions with our general partner or any of its affiliates, including, without limitation, buying or selling properties from or to our general partner and any of its affiliates and borrowing and lending money from or to our general partner and any of its affiliates, subject to limitations contained in our partnership agreement and the Delaware Revised Uniform Limited Partnership Act. The indentures governing our indebtedness contain certain covenants applicable to transactions with affiliates. Investment Mr. Icahn, along with his affiliates (excluding Icahn Enterprises and Icahn Enterprises Holdings), makes investments in the Investment Funds. During the second quarter of 2013, an affiliate of Mr. Icahn invested $45 million in the Investment Funds. As of June 30, 2013 and December 31, 2012, the total fair market value of investments in the Investment Funds made by Mr. Icahn and his affiliates (excluding Icahn Enterprises and Icahn Enterprises Holdings) was approximately $3.8 billion and $3.5 billion, respectively. Effective April 1, 2011, based on an expense-sharing arrangement, certain expenses borne by Icahn Capital are reimbursed by the Investment Funds, generally when such expenses are paid. Such expenses relate to the operation, administration and investment activities of Icahn Capital for the benefit of the Investment Funds (including salaries, benefits and rent) and are allocated pro rata in accordance with each investor's capital accounts in the Investment Funds. For the three months ended June 30, 2013 and 2012, $13 million and $7 million, respectively, was allocated to the Investment Funds based on this expense-sharing arrangement. For the six months ended June 30, 2013 and 2012, $40 million and $11 million, respectively, was allocated to the Investment Funds based on this expense-sharing arrangement. 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"). 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 certain 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 such tank railcars during the term of the agreement. Subject to certain early termination events, the agreement will terminate on December 31, 2014. In consideration of 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 percent 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 shall be provided at fair market value. Under the agreement, ACF has 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 December 31, 2014. 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. Revenues under this agreement were $3 million for each of the three and six months ended June 30, 2013 and were recorded for sales of railcar components to ACF and for royalties on railcars sold by ACF. In April 2013, AEP Leasing entered into an agreement ("ACF Agreement") with ACF whereby AEP Leasing will purchase 1,050 railcars from ACF in 2013 and 2014 for an aggregate purchase price of approximately $150 million. Additionally, AEP Leasing has an option to purchase an additional 500 railcars in 2013 and 2014 for an aggregate additional purchase price of approximately $70 million. 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 no 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 by AEP Leasing from ACF were $5 million for each of the three and six months ended June 30, 2013. Agreements with American Railcar Leasing LLC In April 2011, ARI entered into a fleet services agreement ("Railcar Services Agreement") with ARL, a company controlled by Mr. Icahn, for a term of three years, which will automatically renew for additional one-year periods unless either party provides at least 60 days written prior notice of termination. Pursuant to the Railcar Services Agreement, ARI provides railcar repair, engineering, administrative and other services, on an as needed basis, for ARL's lease fleet at mutually agreed-upon prices. Railcar services revenues, included in other revenues from operations in our consolidated statements of operations, recorded by ARI under this agreement were $5 million and $6 million for the three months ended June 30, 2013 and 2012, respectively, and $9 million and $11 million for the six months ended June 30, 2013 and 2012, respectively. The Railcar Services Agreement was unanimously approved by the independent directors of ARI's audit committee on the basis that the terms were no less favorable than those terms that could have been obtained in a comparable transaction with an unaffiliated third party. ARI has from time to time manufactured and sold railcars to ARL under long-term agreements as well as on a purchase order basis. In the third quarter of 2012, all unfilled purchase orders previously placed by ARL were assigned to AEP Leasing. Revenues for railcars sold to ARL were approximately $11 million for each of the three and six months ended June 30, 2012. The terms and pricing on sales to related parties are not less favorable to ARI than the terms and pricing on sales to unaffiliated third parties. Any related party sales of railcars under an agreement or purchase order have been and will be subject to the approval or review by the independent directors of Icahn Enterprises' and ARI’s audit committee. On February 29, 2012, ARI entered into a railcar management agreement (the "ARI Railcar Management Agreement") with ARL, pursuant to which ARI engaged ARL to sell or lease ARI's railcars in certain markets, subject to the terms and conditions of the ARI Railcar Management Agreement. The ARI 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. In December 2012, a subsidiary of ARI entered into a similar agreement with ARL that terminates in August 2018.

The AEP Railcar Management Agreement was effective as of August 30, 2012, will continue through December 31, 2022 and may be renewed upon written agreement by both parties. The ARI Railcar Management Agreement and the AEP Railcar Management Agreement (collectively the "Railcar Management Agreements") also provide that ARL will manage ARI's and AEP Leasing'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 receives, 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 ARI Railcar Management Agreement was unanimously approved by ARI's special committee and Icahn Enterprises' audit committee, which were advised by independent counsel and an independent financial advisor. The AEP Railcar Management Agreement was unanimously approved by Icahn Enterprises' audit committee, which was advised by independent counsel and an independent financial advisor. Each of the Railcar Management Agreements was approved by the applicable special or audit committees on the basis that the terms of the Railcar Management Agreements were no less favorable than those terms that could have been obtained in a comparable transaction with an unaffiliated third party. Combined fees incurred by ARI and AEP Leasing in connection with the Railcar Management Agreements were immaterial for each of the three and six months ended June 30, 2013 and 2012. As of June 30, 2013 and December 31, 2012, our Railcar segment had accounts receivable of $4 million and $2 million, respectively, due from ARL and ACF. These amounts are included in other assets in our consolidated balance sheets. Insight Portfolio Group LLC (formerly known as Icahn Sourcing, LLC) Icahn Sourcing, LLC ("Icahn Sourcing") was an entity formed 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 2013. In addition to the minority equity interest held by Icahn Enterprises Holdings, certain subsidiaries of Icahn Enterprises Holdings, including Federal-Mogul, CVR, Tropicana, ARI, 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 in 2013. 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 in 2013.
