We lease 79 B717 aircraft through various lessors, under leases with terms that expire through 2022. We have the option to renew the B717 leases for periods ranging from one to four years. The B717 leases have purchase options at or near the end of the lease term at fair market value, and two have purchase options based on a stated percentage of the lessor’s defined cost of the aircraft at the end of the thirteenth year of the lease term. Each of the leases contains return conditions that must be met prior to the termination of the leases. Forty-one of the B717 leases are the result of sale/leaseback transactions. Deferred gains from these transactions are being amortized over the terms of the leases. At December 31, 2006 and 2005, unamortized deferred gains were $59.7 million and $62.4 million, respectively. We also lease facilities from local airport authorities or other carriers, as well as office space under operating leases with terms ranging up to 12 years. In addition, we lease spare engines and certain rotables under capital leases.
