Basis of Presentation	1. Basis of Presentation *The Business—Gogo Inc. (“we”, “us”, “our”) is a holding company, which through its operating subsidiaries is a provider of in-flight connectivity and wireless in-cabin digital entertainment solutions. We operate through the following three segments: Commercial Aviation North America or “CA-NA”, Commercial Aviation Rest of World or “CA-ROW” and Business Aviation or “BA”. Services provided by our CA-NA and CA-ROW businesses include Passenger Connectivity, which allows passengers to connect to the Internet from their personal Wi-Fi-enableddevices; Passenger Entertainment, which offers passengers the opportunity to enjoy a broad selection of in-flight entertainment options on their personal Wi-Fi-enabled devices; and Connected Aircraft Services (“CAS”), which offers airlines connectivity for various operations and currently include, among others, real-time credit card transaction processing, electronic flight bags and real-time weather information. Services are provided by CA-NA on commercial aircraft flying routes that generally begin and end within North America, which for this purpose includes the United States, Canada and Mexico. CA-ROW provides service on commercial aircraft operated by foreign-based commercial airlines and flights outside of North America for North American-based commercial airlines. The routes included in our CA-ROW segment are those that begin and/or end outside of North America (as defined above) on which our international service is provided. BA provides in-flight Internet connectivity and other voice and data communications products and services and sells equipment for in-flight telecommunications to the business aviation market. BA services include Gogo Biz, our in-flight broadband service, Passenger Entertainment, our in-flight entertainment service, and satellite-based voice and data services through our strategic alliances with satellite companies.

Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements and should be read in conjunction with our annual audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016 as filed with the Securities and Exchange Commission (“SEC”) on February 27, 2017 (the “2016 10-K”).

The results of operations and cash flows for the nine month period ended September 30, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2017. We have one class of common stock outstanding as of September 30, 2017 and December 31, 2016. Use of Estimates*—The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis, management evaluates the significant estimates and bases such estimates on historical experience and on various other assumptions believed to be reasonable under the circumstances. However, actual results could differ materially from those estimates. Under agreements with certain of our airline partners to upgrade our equipment on certain aircraft or decommission certain aircraft on which our equipment is installed, on a quarterly basis we reassess the useful life of the affected equipment. As a result, we shorten the useful lives of the affected equipment to be consistent with the estimated upgrade date or aircraft decommissioning date, as applicable. We also shorten the remaining amortization period for deferred airborne lease incentives for certain equipment on aircraft to be decommissioned. The change in estimated useful lives related to these events resulted in increases in depreciation expense of $8.6 million and $14.9 million, respectively, in the three and nine month periods ended September 30, 2017 and increases in the amortization of deferred airborne lease incentives, which reduced our cost of service revenue, of $1.3 million and $3.5 million, respectively, in the three and nine month periods ended September 30, 2017. As a result, net loss per basic and fully diluted share increased by $0.09 and $0.14, respectively, for the three and nine month periods ended September 30, 2017.
