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"), an affiliate of Mr. Icahn. The agreement was unanimously approved by the independent directors of ARI’s and Icahn Enterprises' audit committees 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. In August 2014, ARI and ACF amended this agreement to, among other things, extend the termination date from December 31, 2014 to December 31, 2015, subject to certain early termination events. In consideration for 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 expenditures. 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 had 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, 2015. 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. ARI's revenues under this agreement were $4 million and $3 million for the three months ended September 30, 2014 and 2013, respectively, and $16 million and $7 million for the nine months ended September 30, 2014 and 2013, respectively, and were recorded for sales of railcar components to ACF and for royalties and profits on railcars sold by ACF.

The ACF Agreement was assumed by ARL in connection with our purchase of a 75% economic interest in ARL. 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 not 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 from ACF were $36 million and $20 million for the three months ended September 30, 2014 and 2013, respectively, and $99 million and $25 million for the nine months ended September 30, 2014 and 2013, respectively.
