COMMITMENTS AND CONTINGENCIES

Lease Commitments

The Company leases portions of the air park in Wilmington, Ohio, under lease agreements with a regional port authority, the terms of which expire in May of 2019 and June of 2036 with options to extend the leases. The leased facilities include corporate offices, 310,000 square feet of maintenance hangars and a 100,000 square foot component repair shop at the air park. ABX also has the non-exclusive right to use the airport, which includes one active runway, taxi ways and ramp space. The Company also leases and operates a 311,500 square foot, two hangar aircraft maintenance complex in Tampa, Florida. Additionally, the Company leases certain equipment, airport facilities, office space and maintenance facilities at locations outside of the airpark in Wilmington.

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 September 30, 2017, the Company was committed to acquire and modify additional Boeing 767-300 passenger aircraft into standard freighter aircraft. In addition to three Boeing 767-300 aircraft that were in the modification process at September 30, 2017, the Company is committed to induct six more aircraft into the freighter modification process through 2018. As of September 30, 2017, the Company's commitments to complete the conversions of aircraft it owns or has the contracts to purchase totaled $124.5 million. 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 September 2015, the Company entered into a joint venture agreement to establish an express cargo airline serving multiple destinations within the People's Republic of China (including Hong Kong, Macau and Taiwan) and surrounding countries, pending governmental approvals. The Company's contributions to the joint venture have been minimal and are expected to remain so over the next several months. Obtaining required governmental approvals for any new airline has since been delayed and as a result, the Company is evaluating alternatives. The Company is seeking to develop other aircraft investments in China by leveraging the relationship developed by Pemco, which provides modified Boeing 737 freighter aircraft in China.

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.
