Purchase Commitments

The Company has agreements with Israel Aerospace Industries Ltd. ("IAI") for the conversion of Boeing 767 passenger aircraft into a standard configured freighter aircraft. The conversions primarily consist of the installation of a standard cargo door and loading system. At December 31, 2017, the Company was committed to acquire and modify additional Boeing 767-300 passenger aircraft into standard freighter aircraft. In addition to four aircraft that were in the modification process at December 31, 2017, the Company is committed to induct four more aircraft into the freighter modification process through 2018, including commitments to purchase two more Boeing 767-300 passenger aircraft during the first quarter of 2018.

Additionally, the Company could incur a cancellation fee for part kits for any aircraft that is not inducted into conversion at IAI.

Guarantees and Indemnifications

Certain leases and agreements of the Company contain guarantees and indemnification obligations to the lessor, or one or more other parties that are considered reasonable and customary (e.g. use, tax and environmental indemnifications), the terms of which range in duration and are often limited. Such indemnification obligations may continue after expiration of the respective lease or agreement.

Other

In addition to the foregoing matters, the Company is also a party to legal proceedings, including FAA enforcement actions, in various federal and state jurisdictions from time to time arising out of the operation of the Company's business. The amount of alleged liability, if any, from these proceedings cannot be determined with certainty; however, the Company believes that its ultimate liability, if any, arising from pending legal proceedings, as well as from asserted legal claims and known potential legal claims which are probable of assertion, taking into account established accruals for estimated liabilities, should not be material to our financial condition or results of operations.
