Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company is subject to comprehensive federal, state, local and international environmental laws and regulations relating to the release or discharge of materials into the environment, the management, use, processing, handling, storage, transport or disposal of hazardous materials and wastes, and other laws and regulations relating to the protection of human health and the environment. These laws and regulations not only expose ARI to liability for the environmental condition of its current or formerly owned or operated facilities, and its own negligent acts, but also may expose ARI to liability for the conduct of others or for ARI’s actions that were in compliance with all applicable laws at the time such actions were taken. In addition, these laws may require significant expenditures to achieve compliance and are frequently modified or revised to impose new obligations. Civil and criminal fines and penalties and other sanctions may be imposed for non-compliance with these environmental laws and regulations. ARI’s operations that involve hazardous materials also raise potential risks of liability under common law. Certain real property ARI acquired from ACF Industries LLC (ACF) in 1994 had been involved in investigation and remediation activities to address contamination both before and after their transfer to ARI. ACF is an affiliate of Mr. Carl Icahn, the Company’s principal beneficial stockholder through Icahn Enterprises L.P. (IELP). Substantially all of the issues identified with respect to these properties relate to the use of these properties prior to their transfer to ARI by ACF and for which ACF has retained liability for environmental contamination that may have existed at the time of transfer to ARI. ACF has also agreed to indemnify ARI for any cost that might be incurred with those existing issues. As of the date of this report, ARI does not believe it will incur material costs in connection with activities relating to these properties, but it cannot assure that this will be the case. If ACF fails to honor its obligations to ARI, ARI could be responsible for the cost of any additional investigation or remediation that may be required. The Company believes that its operations and facilities are in substantial compliance with applicable laws and regulations and that any noncompliance is not likely to have a material adverse effect on its financial condition or results of operations. ARI is a party to collective bargaining agreements with labor unions at two repair facilities that will expire in September 2016 and January 2021. ARI is also party to a collective bargaining agreement with a labor union at a parts manufacturing facility that will expire in April 2017. The Company has various agreements with and commitments to related parties. See Note 15, Related Party Transactions, for further detail. Certain claims, suits and complaints arising in the ordinary course of business have been filed or are pending against ARI. In the opinion of management, all such claims, suits, and complaints arising in the ordinary course of business are without merit or would not have a significant effect on the future liquidity, results of operations or financial position of ARI if disposed of unfavorably. On October 24, 2014, the Company filed a complaint in United States District Court for the Southern District of New York against Gyansys, Inc. (Gyansys). The complaint asserts a claim against Gyansys for breaching its contract with ARI to implement an enterprise resource planning system. The Company seeks to recover monetary damages in an amount still to be determined, but which ARI alleged exceeds $25 million. Gyansys filed a response to the suit denying its responsibility. It also counterclaimed against ARI for a breach of contract and wrongful termination, seeking damages in excess of $10 million and equitable relief. At this time, the Company does not have sufficient information to reasonably form an estimate of the potential outcome (gain or loss) of this litigation. On September 9, 2015, the court denied ARI's motion to dismiss the wrongful termination counterclaim. A trial date has been tentatively scheduled for September 12, 2016. However, the Company continues to believe that Gyansys' counterclaims lack merit and will continue to vigorously defend against these counterclaims.
