Segment Reporting |
Segment Reporting | (2) Segment Reporting Generally accepted accounting principles require disclosures related to components of a company for which separate financial information is available to, and regularly evaluated by, the Company’s chief operating decision maker when deciding how to allocate resources and in assessing performance. The Company’s three reporting segments consist of the operations of SkyWest Airlines, ExpressJet and SkyWest Leasing activities. Corporate overhead expenses incurred by the Company are allocated to the operating expenses of SkyWest Airlines and ExpressJet. The Company’s chief operating decision maker analyzes the profitability of operating the E175 aircraft (including operating costs and associated revenue) separately from the profitability of the Company’s ownership, financing costs and associated revenue of the Company’s E175 aircraft (including depreciation expense, interest expense and associated revenue). The SkyWest Leasing segment includes revenue attributed to the Company’s E175 aircraft ownership cost earned under the applicable fixed-fee contracts and the depreciation and interest expense of the Company’s E175 aircraft. The SkyWest Leasing segment’s total assets and capital expenditures include the acquired E175 aircraft. The SkyWest Leasing segment additionally includes the activity of four CRJ200 aircraft leased to a third-party. The following represents the Company’s segment data for the years ended December 31, 2017, 2016 and 2015 (in thousands).
