A percentage of the Company's unionized Employees, including its Flight Attendants, Customer Service Agents, Mechanics, Flight Simulator Technicians, and Material Specialists, are in discussions on labor agreements. Those unionized Employee groups in discussions represent approximately </font><font style="font-family:inherit;font-size:11pt;">43 percent</font><font style="font-family:inherit;font-size:11pt;"> of the Company’s full-time equivalent Employees as of </font><font style="font-family:inherit;font-size:11pt;">December 31, 2018</font><font style="font-family:inherit;font-size:11pt;">. </font></div><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">The Company attempts to minimize its concentration risk with regards to its cash, cash equivalents, and its investment portfolio. This is accomplished by diversifying and limiting amounts among different counterparties, the type of investment, and the amount invested in any individual security or money market fund.</font></div><div style="line-height:120%;text-align:justify;text-indent:41px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">To manage risk associated with financial derivative instruments held, the Company selects and will periodically review counterparties based on credit ratings, limits its exposure to a single counterparty, and monitors the market position of the program and its relative market position with each counterparty. The Company also has agreements with counterparties containing early termination rights and/or bilateral collateral provisions whereby security is required if market risk exposure exceeds a specified threshold amount or credit ratings fall below certain levels. Collateral deposits provided to or held from counterparties serve to decrease, but not totally eliminate, the credit risk associated with the Company’s hedging program. See </font><font style="font-family:inherit;font-size:11pt;">Note 10</font><font style="font-family:inherit;font-size:11pt;"> for further information.</font></div><div style="line-height:120%;text-align:justify;text-indent:41px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">As of </font><font style="font-family:Times New Roman;font-size:11pt;color:#000000;font-style:normal;font-weight:normal;text-decoration:none;">December 31, 2018</font><font style="font-family:inherit;font-size:11pt;">, the Company operated an all-Boeing fleet, all of which are variations of the Boeing 737. If the Company were unable to acquire additional aircraft or associated aircraft parts from Boeing, or Boeing were unable or unwilling to make timely deliveries of aircraft or associated parts, or to provide adequate support for its products, the Company’s operations would be materially adversely impacted. In addition, the Company would be materially adversely impacted in the event of a mechanical or regulatory issue associated with the Boeing 737 aircraft type, whether as a result of downtime for part or all of the Company’s fleet, increased maintenance costs, or because of a negative perception by the flying public. The Company is also dependent on sole or limited suppliers for aircraft engines and certain other aircraft parts and services and would, therefore, also be materially adversely impacted in the event of the unavailability of, inadequate support for, or a mechanical or regulatory issue associated with, engines and other parts.</font></div><div style="line-height:120%;text-align:justify;text-indent:41px;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">The Company has historically entered into agreements with some of its co-brand, payment, and loyalty partners that contain exclusivity aspects which place certain confidential restrictions on the Company from entering into certain arrangements with other payment and loyalty partners. These arrangements generally extend for the terms of the agreements, which typically are for five to seven years, but none of which are more than 10 years in length. Some of these agreements automatically renew on an annual basis, unless either party objects to such extension. The Company believes the financial benefits generated by the exclusivity aspects of these arrangements outweigh the risks involved with such agreements.</font></div></div> |
