Commitments, Contingencies, and Concentrations [Abstract] |
Commitments, Contingencies, and Concentrations | (13) Commitments, Contingencies, and Concentrations Commitments As of December 31, 2013, the Company had open purchase commitments totaling $194.2 million for sixty aircraft scheduled to be delivered from 2014 through 2017. Typically the Company has financed aircraft acquired under similar commitments through capital lease or debt agreements. If financing arrangements cannot be arranged or the Company is prevented from taking or declines to take delivery of the aircraft under the commitments described above for any other reason, the Company may forfeit nonrefundable deposits of approximately $18.3 million. The amount of deposit to be forfeited may be mitigated if the aircraft manufacturer is able to remarket the commitment positions. As of December 31, 2013, the Company has received financing commitments, subject to routine credit approval and aircraft inspection processes, to cover the cost of all aircraft scheduled to be delivered in 2014. The Company intends to use the new aircraft for expansion opportunities as well as to replace older models of aircraft in the fleet. The Company plans to either sell the aircraft which are replaced, use them for spare parts, or redeploy them into the backup fleet.
| As of December 31, 2013, the Company had three letters of credit totaling $3,525,000 in lieu of cash deposits on workers compensation insurance policies and other obligations. All letters of credit may be renewed annually and reduce the available borrowing capacity under the Company’s revolving credit facility.
Contingencies On January 30, 2013, the Company was served with a purported class action lawsuit, filed in the Superior Court of Alameda County, California, alleging failure to pay certain compensation and benefits to employees in that jurisdiction. The Company continues to evaluate the merits of the lawsuit and is vigorously defending against this suit. The Company has recorded a liability based on its assessment of potential outcomes. Adjustments to this liability, which may or may not be material, may be required as the case progresses. The Company is involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Company’s consolidated financial position, results of operations, or liquidity. Concentrations
