Table of Contents
The table below summarizes United’s commitments as of December 31, 2016, which primarily relate to the acquisition of aircraft and related spare engines, aircraft improvements and include other capital purchase commitments for the years ended December 31 (in billions). Any new firm aircraft orders, including through the exercise of purchase options and purchase rights, will increase the total future capital commitments of the Company.
In the first quarter of 2017, the Company announced that it will retire its fleet of Boeing 747 aircraft from scheduled service by the end of 2017. The Company does not expect there to be a material impact to depreciation and amortization expense.
As of December 31, 2016, United had $1.3 billion in financing available through EETC transactions for the financing of all of its aircraft deliveries scheduled in the first half of 2017. See Note 11 of this report for additional information on aircraft financing. The Company has also secured backstop financing commitments from certain of its aircraft manufacturers for a limited number of its future aircraft deliveries, subject to certain customary conditions. Financing may be necessary to satisfy the Company’s capital commitments for its firm order aircraft and other related capital expenditures.
