Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Principles of Consolidation—The consolidated financial statements include our wholly owned subsidiaries and, prior to its dissolution in 2014, our affiliate, AC Management LLC (“ACM”). All intercompany transactions and account balances have been eliminated.

We were the managing member of ACM, an affiliate whose units were owned by members of management. ACM was established for the sole purpose of providing an ownership stake in us to members of management, and ACM’s transactions effectively represent a stock-based compensation plan (see Note 11, “Stock-Based Compensation Expense,” for further information). Since we were the managing member of ACM and thereby controlled ACM, including controlling which members of management were granted ownership interests, ACM was included in our consolidated financial statements prior to its dissolution in 2014.

Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“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 revenues 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.

Revisions—During the three months ended September 30, 2016, we determined that it was necessary to revise the presentation of our investments in U.S. Treasury bills as short-term investments, rather than as cash and cash equivalents, in the consolidated balance sheets. Therefore, changes in our short-term investments are included in cash flows from investing activities in our consolidated statements of cash flows.

Our short-term investments are comprised of investments in U.S. Treasury bills with remaining maturities at the date of purchase of more than three months but less than twelve months. We have the intent and ability to hold our short-term investments to maturity at the time of purchase and we reevaluate such determination each reporting period. Therefore, we classify our short-term investments as held-to-maturity.

We assessed the materiality of these classification changes, taking into account quantitative and qualitative factors, and determined them to be immaterial to the consolidated balance sheet as of December 31, 2015 and to the consolidated statement of cash flows for the years ended December 31, 2015 and 2014. There is no impact to the consolidated statements of operations for any period reported.

While these immaterial classification changes could have been reflected prospectively, we elected to revise the previously reported consolidated balance sheet and consolidated statement of cash flows in order to provide greater comparability for the periods presented. Therefore, we have revised the previously reported cash and cash equivalents to reflect the classification of our investments in U.S. Treasury bills as short-term investments on the balance sheet as of December 31, 2015. Additionally, we have revised previously reported net cash used in investing activities in the consolidated statement of cash flows for the years ended December 31, 2015 and 2014 to include changes in our short-term investments.

Below are the line items from our consolidated balance sheet as of December 31, 2015 illustrating the effect of these immaterial revisions (in thousands):

Significant Risks and Uncertainties—Our operations are subject to certain risks and uncertainties, including without limitation those associated with continuing losses, fluctuations in operating results, funding expansion, strategic alliances, capacity constraints, managing rapid growth and expansion, relationships with customers, suppliers and distributors, financing arrangement terms that may restrict operations, regulatory issues, competition, the economy, technology trends and evolving industry standards.

Cash, Cash Equivalents and Short-Term Investments—We consider cash and cash equivalents to be short-term, highly liquid investments that have the following characteristics: readily convertible to known amounts of cash, so near their maturities that there is insignificant risk of changes in value due to any changes in market interest rates, and having maturities of three months or less when purchased. We continually monitor positions with, and the credit quality of, the financial institutions with which we invest. The carrying amounts reported in the balance sheets for cash and cash equivalents approximate the fair market value of these assets.

We consider short-term investments to be investments with maturities of twelve months or less (but greater than three months). Currently all our short-term investments are comprised of U.S. Treasury bills, which we intend to hold to maturity.

Certain cash amounts are restricted as to use and are classified outside of cash and cash equivalents. See Note 6, “Long-term Debt and Other Liabilities,” for further details.

Concentrations of Credit Risk—Financial instruments that potentially subject us to a concentration of credit risk consist principally of cash and cash equivalents, short-term investments and accounts receivable. All cash and cash equivalents are invested with creditworthy financial institutions. We perform ongoing credit evaluations and generally do not require collateral to support receivables. Our short-term investments are all comprised of U.S. Treasury bills.

See Note 10, “Business Segments and Major Customers,” for further details.

Income Tax—We use an asset and liability-based approach in accounting for income taxes. Deferred income tax assets and liabilities are recorded based on the differences between the financial statement and tax bases of assets and liabilities, applying enacted statutory tax rates in effect for the year in which the tax differences are expected to reverse. Valuation allowances are provided against deferred tax assets which are not likely to be realized. On a regular basis, management evaluates the recoverability of deferred tax assets and the need for a valuation allowance. We also consider the existence of any uncertain tax positions and, as necessary, provide a reserve for any uncertain tax positions at each reporting date.

See Note 13, “Income Tax,” for further details.

Inventories—Inventories consist primarily of telecommunications systems and parts, and are recorded at the lower of cost (average cost) or market. We evaluate the need for write-downs associated with obsolete, slow-moving and nonsalable inventory by reviewing net realizable inventory values on a periodic basis.

See Note 4, “Composition of Certain Balance Sheet Accounts,” for further details.

Property and Equipment and Depreciation—Property and equipment, including leasehold improvements, are stated at historical cost, less accumulated depreciation. Network asset inventory and construction in progress, which include materials, transmission and related equipment, and interest and other costs relating to the construction and development of our network, are not depreciated until they are put into service. Network equipment consists of switching equipment, antennas, base transceiver stations, site preparation costs, and other related equipment used in the operation of our network. Airborne equipment consists of routers, modems, radomes, antennas and related equipment, and accessories installed or to be installed on aircraft. Depreciation expense totaled $84.1 million, $69.4 million and $53.4 million for the years ended December 31, 2016, 2015 and 2014, respectively. Depreciation of property and equipment is computed using the straight-line method over the estimated useful lives for owned assets, which are as follows:


Office equipment, furniture, fixtures and other			3-7 years
Leasehold improvements			3-13 years
Airborne equipment			7 years
Network equipment			5-25 years

See Note 4, “Composition of Certain Balance Sheet Accounts,” for further details.

Improvements to leased property are amortized over the shorter of the useful life of the improvement or the term of the related lease. Repairs and maintenance costs are expensed as incurred.

Due to advances in technology and changes in agreements with our airline partners, with respect to upgrading equipment, we periodically reassess the useful lives of our property and equipment. Such reassessment has resulted in the useful life of specific assets being adjusted to a shorter period than originally estimated, resulting in an increase in annual depreciation expense for those assets.

Goodwill and Other Intangible Assets—Goodwill and other intangible assets with indefinite lives are not amortized, but are reviewed for impairment at least annually or whenever events or circumstances indicate the carrying value of the asset may not be recoverable. Our FCC Licenses (as defined in Note 5, “Intangible Assets”) are our only indefinite-lived intangible assets. We perform our annual impairment tests of goodwill and our FCC Licenses during the fourth quarter of each fiscal year. We assess qualitative factors to determine the likelihood of impairment. Our qualitative analysis includes, but is not limited to, assessing the changes in macroeconomic conditions, regulatory environment, industry and market conditions, financial performance versus budget and any other events or circumstances specific to goodwill and the FCC Licenses. If it is more likely than not that the fair value of goodwill and the FCC Licenses is greater than the carrying value, no further testing is required. Otherwise, we will apply the quantitative impairment test method.

Our quantitative impairment testing of the FCC Licenses uses the Greenfield method, an income-based approach. When performing this quantitative impairment testing, we estimate the fair value of the goodwill and FCC Licenses asset balances based primarily on projected future operating results, discounted cash flows, and other assumptions. Projected future operating results and cash flows used for valuation purposes may reflect considerable improvements relative to historical periods with respect to, among other things, revenue growth and operating margins. Although we believe our projected future operating results and cash flows and related estimates regarding fair values are based on reasonable assumptions, projected operating results and cash flows may not always be achieved. The failure to achieve one or more of our assumptions regarding projected operating results and cash flows in the near term or long term could reduce the estimated fair value below carrying value and result in the recognition of an impairment charge. The results of our annual goodwill and indefinite-lived intangible asset impairment assessments for 2016, 2015 and 2014 indicated no impairment.

Intangible assets that are deemed to have a finite life are amortized over their useful lives as follows:


Software			3-8 years
OEM and dealer relationships			10 years
Service customer relationships			5-7 years
Other intangible assets			4-12 years

See Note 5, “Intangible Assets,” for further details.

Long-Lived Assets—We review our long-lived assets to determine potential impairment whenever events indicate that the carrying amount of such assets may not be recoverable. We do this by comparing the carrying value of the long-lived assets with the estimated future undiscounted cash flows expected to result from the use of the assets, including cash flows from disposition. If we determine an impairment exists, the asset is written down to estimated fair value. There were no impairments of long-lived assets in 2016, 2015 and 2014.

Arrangements with Commercial Airlines—Pursuant to contractual agreements with our airline partners, we place our equipment on commercial aircraft operated by the airlines for the purpose of delivering our service to passengers on the aircraft. Depending on the agreement, we may be responsible for the costs of installing and/or deinstalling the equipment. Under one type of connectivity agreement we maintain legal title to our equipment; however, under a second, more prevalent type of connectivity agreement some of our airline partners make an upfront payment and take legal title to such equipment. The majority of the equipment transactions involve the transfer of legal title but have not met sales recognition for accounting purposes because the risks and rewards of ownership are not fully transferred due to our continuing involvement with the equipment, the length of the term of our agreements with the airlines and restrictions in the agreements regarding the airlines’ use of the equipment. We account for these equipment transactions as operating leases of space for our equipment on the aircraft. The assets are recorded as airborne equipment on our balance sheets, as noted in the Property and Equipment and Depreciation section above. Any upfront equipment payments are accounted for as lease incentives and recorded as deferred airborne lease incentives on our balance sheets and are recognized as a reduction of the cost of service revenue on a straight-line basis over the term of the agreement with the airline.

Additionally, equipment transactions under one form of agreement, which we have used on a limited basis but expect to use more in the future, qualify for sale treatment due to the specific provisions of the agreement.

In the majority of our agreements with commercial airlines, we are required to pay the airline a percentage of the service revenues generated from transactions with the airline’s passengers. Such payments are essentially contingent rental payments and are recorded at the same time as the related passenger service revenue and classified as cost of service revenue in the consolidated statements of operations. Certain airlines are also entitled under their contracts to reimbursement by us for certain costs, which are deemed additional rental payments and classified as cost of service revenue in our consolidated statements of operations.

See Note 14, “Leases,” for further details.

Revenue Recognition—Service revenue for CA-NA and CA-ROW primarily consists of point-of-sale transactions with airline passengers, which are recognized as the services are provided and billed to customers, typically by credit or debit card. The card processors charge a transaction fee for each card transaction, and such transaction processor payments are classified as cost of service revenue in the consolidated statements of operations and recorded at the same time as the related passenger service revenue.

CA-NA’s product offerings also include an annual subscription product and an unlimited monthly access option. Under the annual subscription product, revenue is recognized evenly throughout the year, regardless of how many times the customer accesses the network. Under the unlimited monthly access option, revenue is recognized throughout the month starting on the date of purchase, regardless of how many times the customer accesses the network. All deferred revenue amounts related to the annual subscription, multi-packs and unlimited monthly access options are classified as a current liability in our consolidated balance sheets.

CA-NA and CA-ROW also derive service revenue under arrangements with various third parties who sponsor free or discounted access to our service. The sponsorship arrangements vary with respect to duration and the airlines included. For sponsorship arrangements that occur across more than a single calendar month, revenue is deferred and recognized evenly throughout the sponsorship term. Other sources of CA-NA and CA-ROW revenue includes fees paid by third parties to advertise on or to enable e-commerce transactions through our airborne portal. For advertising or e-commerce arrangements that occur across more than a single calendar month, revenue is deferred and recognized evenly throughout the term of the arrangement.

CA-NA and CA-ROW also derive revenue from Connected Aircraft Services, or CAS. Under these arrangements, fixed-fee revenue (contractual allowance of megabytes or “MB”) may be deferred and recognized evenly over the year of service and a per-MB usage (overage) charge is recognized in the month it was consumed.

We recognize revenue for equipment sales when the following conditions have been satisfied: the equipment has been shipped to the customer, title and risk of loss and control have transferred to the customer, we have no future obligations for installation or maintenance service, the price is fixed or determinable, collectability is reasonably assured and, for the CA-NA and CA-ROW businesses, program launch has occurred. Additionally, when connectivity equipment and services are not separable, the equipment revenue is recognized over the connectivity service term.

We have multi-element arrangements that include equipment, connectivity services, installation and various in-flight entertainment offerings. Revenue is allocated to each element based on the selling price of each element. Each element’s allocated revenue is recognized when the revenue recognition criteria for that element have been met. Fair value is generally based on one of the following three methods: the price charged when each element is sold separately, commonly referred to as vendor-specific objective evidence (“VSOE”); third-party evidence of selling price; or our best estimate of selling price, if neither VSOE or third-party evidence exists. Our BA segment uses VSOE and our CA-NA segment, through certain contracts for equipment and services that are sold direct to our airline partners, uses an estimated selling price to determine the selling price of the elements pertaining to these arrangements.

Service revenue for BA generally consists of monthly recurring and usage fees, which are recognized monthly as the services are provided and billed to customers.

Additionally, CA-NA and CA-ROW charge monthly service fees to our airline partners for network monitoring and portal management services. We recognize these monthly fees as airborne lease incentives (i.e., credit to cost of service revenue) when the services are provided.

Research and Development Costs—Expenditures for research and development are charged to expense as incurred and totaled $45.9 million, $50.1 million and $40.1 million for the years ended December 31, 2016, 2015, and 2014, respectively. Research and development costs are reported as a component of engineering, design and development expenses in our consolidated statements of operations.

Software Development Costs—We capitalize costs for network and non-network software developed or obtained for internal use during the application development stage. These costs include purchased software and direct costs associated with the development and configuration of internal use software that supports the operation of our service offerings. These costs are included in intangible assets, net, in our consolidated balance sheets and, when the software is placed in service, are amortized on a straight-line basis over their estimated useful lives. Costs incurred in the preliminary project and post-implementation stages, as well as maintenance and training costs, are expensed as incurred.

With respect to software sold as part of our equipment sales, we capitalize software development costs once technological feasibility has been established. Capitalized software costs are amortized on a product-by-product basis, based on the greater of the ratio that current gross revenues for a product bear to the total of current and anticipated future gross revenues for that product or the straight-line method over the remaining estimated economic life of the product.

Warranty—We provide warranties on parts and labor related to our products. Our warranty terms range from two to five years. Warranty reserves are established for costs that are estimated to be incurred after the sale, delivery and installation of the products under warranty. The warranty reserves are determined based on known product failures, historical experience and other available evidence, and are included in accrued liabilities in our consolidated balance sheets. See Note 4, “Composition of Certain Balance Sheet Accounts,” for the details of the changes in our warranty reserve.

Asset Retirement Obligations—We have certain asset retirement obligations related to contractual commitments to remove our network equipment and other assets from leased cell sites upon termination of the site lease and to remove equipment from aircraft when the service contracts terminate. The asset retirement obligations are classified as a noncurrent liability in our consolidated balance sheets.

See Note 4, “Composition of Certain Balance Sheet Accounts,” for the details of the changes in our asset retirement obligations.

Fair Value of Financial Instruments—We group financial assets and financial liabilities measured at fair value into three levels of hierarchy based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value.

See Note 9, “Fair Value of Financial Assets and Liabilities,” for further information.

Derivatives—In March 2015, we entered into a prepaid forward transaction in which we purchased 7.2 million shares of our common stock for approximately $140 million, with an expected settlement date on or around March 1, 2020. Because the transaction is indexed to our own stock and classified within stockholders’ equity, we do not account for the prepaid forwards as a derivative instrument in accordance with ASC 815, Derivatives and Hedging.

See Note 6, “Long-Term Debt and Other Liabilities,” Note 8, “Common Stock and Preferred Stock,” and Note 9, “Fair Value of Financial Assets and Liabilities,” for further information.

Convertible Notes—Proceeds received from the issuance of Convertible Notes (as defined in Note 6, “Long-Term Debt and Other Liabilities”) are initially allocated between a liability component (long-term debt) and an equity component (additional paid-in capital), within the consolidated balance sheet. The fair value of the liability component is measured using rates determined for similar debt instruments without a conversion feature. The carrying amount of the equity component, representing the conversion option, is determined by deducting the fair value of the liability component from the aggregate face value of Convertible Notes.

See Note 6, “Long-Term Debt and Other Liabilities,” for further information.

Net Loss Per Share—We calculate basic and diluted net loss per share using the weighted-average number of common shares outstanding during the period.

See Note 3, “Net Loss Per Share,” for further information.

Stock-Based Compensation Expense—Compensation cost is measured and recognized at fair value for all stock-based payments, including stock options. For time-based vesting stock options, we estimate fair value using the Black-Scholes option-pricing model, which requires assumptions, such as expected volatility, risk-free interest rate, expected life, and dividends. Restricted stock units (“RSUs”) and restricted stock are measured based on the fair market value of the underlying stock on the date of grant. For awards with a market condition (which we have used on a limited extent), we estimated fair value using the Monte Carlo Simulation model, which requires assumptions, such as volatility, risk-free interest rate, expected life and dividends. Our stock-based compensation expense is recognized over the applicable vesting period, and is included in the same operating expense line items in the consolidated statements of operations as the base cash compensation paid to the underlying employees. We adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), in December 2016 and ceased recognizing stock-based compensation net of forfeitures and instead recognize forfeitures as they occur.

See Note 11, “Stock-Based Compensation,” for further discussion.

Leases—In addition to our arrangements with commercial airlines which we account for as leases as noted above, we also lease certain facilities, equipment, cell tower space, and base station capacity. We review each lease agreement to determine if it qualifies as an operating or capital lease.

For leases that contain predetermined fixed escalations of the minimum rent, we recognize the related rent expense on a straight-line basis over the term of the lease. We record any difference between the straight-line rent amounts and amounts payable under the lease as deferred rent, in either accrued liabilities or as a separate line within noncurrent liabilities, as appropriate, in our consolidated balance sheets.

For leases that qualify as a capital lease, we record a capital lease asset and a capital lease obligation at the beginning of the lease term at an amount equal to the present value of minimum lease payments during the term of the lease, excluding that portion of the payments that represent executory costs. The capital lease asset is depreciated on a straight-line method over the shorter of its estimated useful life or lease term.

See Note 14, “Leases,” for further information.

Advertising Costs—Costs for advertising are expensed as incurred.

Debt Issuance Costs—We defer loan origination fees and financing costs related to our various debt offerings as deferred financing costs. Additionally, we defer fees paid directly to the lenders related to amendments with our various debt offerings as deferred financing costs. We amortize these costs over the term of the underlying debt obligation using the effective interest method, and include them in interest expense in the consolidated statement of operations. The fees incurred but not paid directly to the lenders in connection with amendments are expensed as incurred to interest expense. Deferred financing costs associated with future debt issuances are written off in the period during which we determine that the debt will no longer be issued.

See Note 6, “Long-Term Debt and Other Liabilities” for further information.

Comprehensive Loss—Comprehensive loss for the years ended December 31, 2016, 2015 and 2014 is net loss plus unrealized losses on foreign currency translation adjustments.

Recently Issued Accounting Pronouncements—

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue From Contracts With Customers (“ASU 2014-09”). This pronouncement outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. The core principle of ASU 2014-09 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additionally, the FASB issued several amendments to the standard, including clarification on accounting for licenses of intellectual property and identifying performance obligations. This guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within the annual reporting periods. Early adoption of the guidance is permitted for annual reporting periods beginning after December 15, 2016, including interim reporting periods within the annual reporting periods. We will adopt this guidance as of January 1, 2018 and we expect to apply this standard using the full retrospective method. During 2016, we established a project team responsible for assessment and implementation of this guidance. While we are continuing to evaluate the impact of the adoption of this guidance on our consolidated financial statements, based on our analysis to date we currently believe that the measurement and timing of recognition of revenue from certain of our commercial aviation and business aviation customers will be impacted. Certain of our commercial airline and business aviation contracts provide service revenue that varies based on usage by passengers and our airline partners. The adoption of this guidance will require consideration as to whether service revenue under such contracts is considered an optional purchase of goods or services, or is considered variable consideration. Additionally, we are continuing to assess the treatment of costs to obtain or fulfill a contract with a customer, including costs to obtain STC’s and sales commissions that may require capitalization and amortization over the anticipated service period. Further, our revenue may be affected by up-front activation fees and penalties estimated at the inception of each arrangement. We are still assessing the impact of these changes to our consolidated financial statements.

In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”). This pronouncement provides additional guidance surrounding the disclosure of going concern uncertainties in the financial statements and requires that management perform interim and annual assessments of an entity’s ability to continue as a going concern for twelve months from the date the financial statements are issued. We adopted this guidance as of December 31, 2016, which did not result in additional disclosures.

In March 2016, the FASB issued ASU 2016-02, Leases (“ASU 2016-02”), which introduces a lessee model that records most leases on the balance sheet. ASU 2016-02 also aligns certain underlying principles of the new lessor model with those in Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (“ASC 606”), the FASB’s new revenue recognition standard. Furthermore, ASU 2016-02 eliminates the required use of bright-line tests used in current GAAP for determining lease classification. It also requires lessors to provide additional transparency into the exposure to the changes in value of their residual assets and how they manage that exposure. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those annual reporting periods. We will adopt this as guidance as of January 1, 2019 and we are currently evaluating the impact of the adoption of this guidance on our consolidated financial statements.

In March 2016, the FASB issued ASU 2016-04, Recognition of Breakage for Certain Prepaid Stored-Value Products (“ASU 2016-04”), which amends the guidance on extinguishing financial liabilities for certain prepaid stored-value products by requiring that entities that sell prepaid stored-value products recognize breakage proportionally as the prepaid stored-value product is being redeemed rather than immediately upon sale of the product. If an entity is unable to estimate breakage, the amount would be recognized when the likelihood becomes remote that the holder will exercise the remaining rights. Entities are required to reassess their estimates of breakage each reporting period. Any change in this estimate would be accounted for as a change in an accounting estimate. An entity that recognizes breakage is required to disclose the methodology used to recognize breakage and significant judgments made in applying the breakage methodology. ASU 2016-04 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years and early adoption is permitted. We can apply ASU 2016-04 by using either a modified retrospective transition approach or a full retrospective transition approach. We will adopt this as guidance as of January 1, 2018 and we are currently evaluating the impact of the adoption of this guidance on our consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, which simplifies several aspects of the accounting for employee share-based payment transactions for both public and nonpublic entities, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. We adopted ASU 2016-09 during the fourth quarter of 2016, which did not have a material impact of the on our consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), which amends ASC 230, Statement of Cash Flows, the FASB’s standards for reporting cash flows in general-purpose financial statements. The amendments address the diversity in practice related to the classification of certain cash receipts and payments including debt prepayment or debt extinguishment costs. We will adopt this guidance as of January 1, 2018 and we expect to apply this standard using the full retrospective method. We do not believe adoption of this guidance will have a material effect on our cash flows as we have historically reported debt prepayment and debt extinguishment costs in a manner consistent with ASU 2016-15.

In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory (“ASU 2016-16”), which removes the prohibition in ASC 740, Income Taxes, against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. This is intended to reduce the complexity of GAAP and diversity in practice related to the tax consequences of certain types of intra-entity asset transfers, particularly those involving intellectual property. ASU 2016-16 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods. We will adopt this guidance as of January 1, 2018 and we are currently evaluating the impact of the adoption of this guidance on our consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18, Restricted Cash—A Consensus of the FASB Emerging Issues Task Force, (“ASU 2016-18”), which amends ASC 230, Statement of Cash Flows, to clarify guidance on the classification and presentation of restricted cash in the statement of cash flows. ASU 2016-18 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods. We will adopt this guidance as of January 1, 2108 and we are currently evaluating the impact of the adoption of this guidance on our consolidated financial statements.

Earnings Per Share [Abstract]

Net Loss Per Share

3. Net Loss Per Share

Basic and diluted net loss per share have been calculated using the weighted-average number of common shares outstanding for the period.

The shares of common stock effectively repurchased in connection with the Forward Transactions (as defined and described in Note 6, “Long-Term Debt and Other Liabilities”) are considered participating securities requiring the two-class method to calculate basic and diluted earnings per share. Net earnings in future periods will be allocated between common shares and participating securities. In periods of a net loss, the shares associated with the Forward Transactions will not receive an allocation of losses, as the counterparties to the Forward Transactions are not required to fund losses. Additionally, the calculation of weighted average shares outstanding as of December 31, 2016 and 2015 excludes approximately 7.2 million shares that will be repurchased as a result of the Forward Transactions.

As a result of the net loss for each of the years ended December 31, 2016, 2015 and 2014 for the periods where such shares or securities were outstanding, all of the outstanding shares of common stock underlying stock options, ACM Units, deferred stock units and restricted stock units were excluded from the computation of diluted shares outstanding because they were anti-dilutive.

The following table sets forth the computation of basic and diluted earnings per share for the years ended December 31, 2016, 2015 and 2014; however, because of the undistributed losses, the shares associated with the Forward Transactions are excluded from the computation of basic earnings per share as undistributed losses are not allocated to these shares (in thousands, except per share amounts):

Goodwill and Intangible Assets Disclosure [Abstract]

Intangible Assets

5. Intangible Assets

Our intangible assets are comprised of indefinite- and finite-lived intangible assets. We own the rights to both 3MHz of ATG spectrum in the nationwide 800 MHz Commercial Air-Ground Radiotelephone band (the “3 MHz FCC License”), which is used in the operation of our ATG network, and the license for 1 MHz of ATG spectrum in the nationwide 800MHz Commercial Air-Ground Radiotelephone band (“1 MHz FCC License”) acquired in the Airfone Acquisition. Together we refer to the 3 MHz FCC License and the 1 MHz FCC License as the “FCC Licenses”. While the FCC Licenses were issued with 10-year terms, such licenses are subject to renewal by the FCC, and renewals of licenses held by others have occurred routinely and at nominal cost. Moreover, we have determined that there are currently no legal, regulatory, contractual, competitive, economic, or other factors that limit the useful life of the FCC Licenses. As a result, the FCC Licenses are treated as indefinite-lived intangible assets which we do not amortize. We reevaluate the useful life of the FCC Licenses each year to determine whether events and circumstances continue to support an indefinite useful life. Our annual impairment assessment of the FCC Licenses for 2016, 2015, and 2014 indicated no impairment.

Our software relates to the development of internal use software which is used to run our network and support our service offerings. Software also includes software embedded in the equipment that we sell to our customers within the BA segment.

Our goodwill balance, all of which related to our BA segment, was $0.6 million as of December 31, 2016 and 2015.

Our intangible assets, other than goodwill, as of December 31, 2016 and 2015 were as follows (in thousands, except for weighted average remaining useful life):

Senior Secured Notes—On June 14, 2016 (the “Issue Date”), Gogo Intermediate Holdings LLC (“GIH”) (a wholly owned subsidiary of Gogo Inc.) and Gogo Finance Co. Inc. (a wholly owned subsidiary of GIH) (the “Co-Issuer” and, together with GIH, the “Issuers”), issued $525 million aggregate principal amount of 12.500% senior secured notes due 2022 (the “Senior Secured Notes”) under an Indenture, dated as of June 14, 2016 (the “Indenture”), among the Issuers, us, as guarantor, certain subsidiaries of GIH, as guarantors (the “Subsidiary Guarantors” and, together with us, the “Guarantors”), and U.S. Bank National Association, as trustee (in such capacity, the “Trustee”) and as collateral agent (in such capacity, the “Collateral Agent”). On December 31, 2016 the outstanding principal balance of the Senior Secured Notes was $525.0 million.

On January 3, 2017, the Issuers issued $65 million aggregate principal amount of additional Senior Secured Notes due 2022 (the “Additional Notes”). The Additional Notes were issued at a price equal to 108% of their face value resulting in gross proceeds of $70.2 million. The Additional Notes have the same terms as the original Senior Secured Notes (as noted below), except with respect to the issue date and issue price and are treated as a single series for all purposes under the Indenture and the security documents that govern the Additional Notes and the original Senior Secured Notes.

Interest on the Senior Secured Notes will accrue at the rate of 12.500% per annum and will be payable semi-annually in arrears on July 1 and January 1, commencing on January 1, 2017 (other than the Additional Notes, for which interest payments commence on July 1, 2017). The Senior Secured Notes mature on July 1, 2022.

We used a portion of the net proceeds from the issuance of the Senior Secured Notes to repay all indebtedness outstanding under the Amended and Restated Senior Term Facility (as defined below), which we prepaid at par plus 3.0% of the principal amount of the loans prepaid in June 2016 (see below for additional details). We intend to use the remaining net proceeds, including the net proceeds from the Additional Notes, for working capital and other general corporate purposes.

We paid approximately $11.4 million of loan origination fees and financing costs related to the issuance of the Senior Secured Notes, which has been accounted for as deferred financing costs. The deferred financing costs on our consolidated balance sheet are being amortized over the contractual term of the Senior Secured Notes using the effective interest method. Total amortization expense was $1.0 million for the year ended December 31, 2016. As of December 31, 2016, the balance of unamortized deferred financing costs related to the Senior Secured Notes was $10.4 million and is included as a reduction to long-term debt in our consolidated balance sheet. See Note 7, “Interest Costs” for additional information.

The Senior Secured Notes are the senior secured indebtedness of the Issuers and are:

•

effectively senior to all of the Issuers’ existing and future senior unsecured indebtedness and the Issuers’ indebtedness secured on a junior priority basis by the same collateral securing the Senior Secured Notes, if any, in each case to the extent of the value of the collateral securing the Senior Secured Notes;

•

effectively senior in right of payment to all of the Issuers’ future indebtedness that is subordinated in right of payment to the Senior Secured Notes;

•

effectively equal in right of payment with the Issuers’ existing and future (i) unsecured indebtedness that is not subordinated in right of payment to the Senior Secured Notes and (ii) indebtedness secured on a junior priority basis by the same collateral securing the Senior Secured Notes, if any, in each case to the extent of any insufficiency in the collateral securing the Senior Secured Notes;

•

structurally senior to all of our existing and future indebtedness, including our Convertible Notes (as defined below); and

•

structurally subordinated to all of the indebtedness and other liabilities of any non-Guarantors (other than the Issuers).

The Senior Secured Notes are guaranteed, on a senior secured basis, by us and all of GIH’s existing and future domestic restricted subsidiaries (other than the Co-Issuer), subject to certain exceptions. The Issuers’ obligations under the Senior Secured Notes are not guaranteed by Gogo International Holdings, LLC, a subsidiary of ours that holds no material assets other than equity interests of our foreign subsidiaries. Each guarantee is a senior secured obligation of such Guarantor and is:

•

effectively senior to all of such Guarantor’s existing and future senior unsecured indebtedness and such Guarantor’s indebtedness secured on a junior priority basis by the same collateral, if any, securing the guarantee of such Guarantor, in each case to the extent of the value of the collateral securing such guarantee;

•

effectively senior in right of payment to all of such Guarantor’s future indebtedness that is subordinated in right of payment to such Guarantor’s guarantee;

•

effectively equal in right of payment with all of such Guarantor’s existing and future (i) unsecured indebtedness that is not subordinated in right of payment to such Guarantor’s guarantee, and (ii) indebtedness secured on a junior priority basis by the same collateral, if any, securing the guarantee of such Guarantor, in each case to the extent of any insufficiency in the collateral securing such guarantee; and

•

structurally subordinated to all indebtedness and other liabilities of any non-Guarantor subsidiary of such Guarantor (excluding, in the case of our guarantee, the Issuers).

The Senior Secured Notes and the related guarantees are secured by first-priority liens, subject to permitted liens, on substantially all of the Issuers’ and the Guarantors’ assets, except for certain excluded assets, including pledged equity interests of the Issuers and all of our existing and future domestic restricted subsidiaries guaranteeing the Senior Secured Notes.

The security interests in certain collateral may be released without the consent of holders of the Senior Secured Notes if such collateral is disposed of in a transaction that complies with the Indenture and related security agreements. In addition, under certain circumstances, we and the Guarantors have the right to transfer certain intellectual property assets that on the Issue Date constitute collateral securing the Senior Secured Notes or the guarantees to a restricted subsidiary organized under the laws of Switzerland, resulting in the release of such collateral without consent of the holders of the Senior Secured Notes.

On or after July 1, 2019, the Issuers may, at their option, at any time or from time to time, redeem any of the Senior Secured Notes in whole or in part. The Senior Secured Notes will be redeemable at the following redemption prices (expressed in percentages of principal amount), plus accrued and unpaid interest, if any, to (but not including) the redemption date (subject to the right of holders of record on the relevant regular record date that are on or prior to the redemption date to receive interest due on an interest payment date), if redeemed during the twelve-month period commencing on July 1 of the following years:


Year	Redemption Price
2019		106.250	%
2020		103.125	%
2021 and thereafter		100.000	%

In addition, at any time prior to July 1, 2019, the Issuers may redeem up to 35% of the aggregate principal amount of the Senior Secured Notes with the proceeds of certain equity offerings at a redemption price of 112.500% of their principal amount, plus accrued and unpaid interest, if any, to (but not including) the date of redemption;provided, however, that Senior Secured Notes representing at least 65% of the principal amount of the Senior Secured Notes remain outstanding immediately after each such redemption.

The Issuers may redeem the Senior Secured Notes, in whole or in part, at any time prior to July 1, 2019, at a redemption price equal to 100% of the principal amount of the Senior Secured Notes redeemed plus the make-whole premium set forth in the Indenture as of, and accrued and unpaid interest, if any, to (but not including) the applicable redemption date.

The Indenture contains covenants that, among other things, limit the ability of the Issuers and the Subsidiary Guarantors and, in certain circumstances, our ability, to: incur additional indebtedness; pay dividends, redeem stock or make other distributions; make investments; create restrictions on the ability of our restricted subsidiaries to pay dividends to the Issuers or make other intercompany transfers; create liens; transfer or sell assets; merge or consolidate; and enter into certain transactions with the Issuers’ affiliates, including us. Most of these covenants will cease to apply if, and for as long as, the Senior Secured Notes have investment grade ratings from both Moody’s Investment Services, Inc. and Standard & Poor’s.

If we or the Issuers undergo specific types of change of control prior to July 1, 2022, GIH is required to make an offer to repurchase for cash all of the Senior Secured Notes at a repurchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to (but not including) the payment date.

The Indenture provides for events of default, which, if any of them occur, would permit or require the principal, premium, if any, and interest on all the then outstanding Senior Secured Notes issued under the Indenture to be due and payable immediately. As of December 31, 2016, no event of default had occurred.

Convertible Notes—On March 3, 2015, we issued $340.0 million aggregate principal amount of 3.75% Convertible Senior Notes due 2020 (the “Convertible Notes”) in a private offering to qualified institutional buyers, pursuant to Rule 144A under the Securities Act. We granted an option to the initial purchasers to purchase up to an additional $60.0 million aggregate principal amount of Convertible Notes to cover over-allotments, of which $21.9 million was subsequently exercised during March 2015, resulting in a total issuance of $361.9 million aggregate principal amount of Convertible Notes. The Convertible Notes mature on March 1, 2020, unless earlier repurchased or converted into shares of our common stock under certain circumstances described below. Upon maturity, we have the option to settle our obligation through cash, shares of common stock, or a combination of cash and shares of common stock. We pay interest on the Convertible Notes semi-annually in arrears on March 1 and September 1 of each year. Interest payments began on September 1, 2015.

The $361.9 million of proceeds received from the issuance of the Convertible Notes was initially allocated between long-term debt (the liability component) at $261.9 million, and additional paid-in-capital (the equity component) at $100.0 million, within the consolidated balance sheet. The fair value of the liability component was measured using rates determined for similar debt instruments without a conversion feature. The carrying amount of the equity component, representing the conversion option, was determined by deducting the fair value of the liability component from the aggregate face value of the Convertible Notes. If we or the note holders elect not to settle the debt through conversion, we must settle the Convertible Notes at face value. Therefore, the liability component will be accreted up to the face value of the Convertible Notes, which will result in additional non-cash interest expense being recognized within the consolidated statements of operations through the Convertible Notes maturity date (see Note 7, “Interest Costs” for additional information). The effective interest rate on the Convertible Notes, including accretion of the notes to par and debt issuance cost amortization, was approximately 11.5%. The equity component will not be remeasured as long as it continues to meet the conditions for equity classification.

As of December 31, 2016 and 2015, the outstanding principal on the Convertible Notes was $361.9 million, the unamortized debt discount was $69.9 million and $87.4 million, respectively, and the net carrying amount of the liability component was $292.0 million and $274.5 million, respectively.

We incurred approximately $10.4 million of issuance costs related to the issuance of the Convertible Notes of which $7.5 million and $2.9 million were recorded to deferred financing costs and additional paid-in capital, respectively, in proportion to the allocation of the proceeds of the Convertible Notes. The $7.5 million recorded as deferred financing costs on our consolidated balance sheet is being amortized over the term of the Convertible Notes using the effective interest method. Total amortization expense of the deferred financing costs was $1.4 million and $1.0 million, respectively, for the years ended December 31, 2016 and 2015. Amortization expense is included in interest expense in the consolidated statements of operations. As of December 31, 2016 and 2015, the balance of unamortized deferred financing costs related to the Convertible Notes was $5.1 million and $6.5 million, respectively, and is included as a reduction to long-term debt in our consolidated balance sheets. See Note 7, “Interest Costs” for additional information.

The Convertible Notes had an initial conversion rate of 41.9274 common shares per $1,000 principal amount of Convertible Notes, which is equivalent to an initial conversion price of approximately $23.85 per share of our common stock. Upon conversion, we currently expect to deliver cash up to the principal amount of the Convertible Notes then outstanding. With respect to any conversion value in excess of the principal amount, we currently expect to deliver shares of our common stock. We may elect to deliver cash in lieu of all or a portion of such shares. The shares of common stock subject to conversion are excluded from diluted earnings per share calculations under the if-converted method as their impact is anti-dilutive.

Holders may convert the Convertible Notes, at their option, in multiples of $1,000 principal amount at any time prior to December 1, 2019, but only in the following circumstances:

•

during any fiscal quarter beginning after the fiscal quarter ended June 30, 2015, if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during the last 30 consecutive trading days of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price of the Convertible Notes on each applicable trading day;

•

during the five business day period following any five consecutive trading day period in which the trading price for the Convertible Notes is less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the Convertible Notes on each such trading day; or

•

upon the occurrence of specified corporate events.

None of the above events allowing for conversion prior to December 1, 2019 occurred during the year ended December 31, 2016. Regardless of whether any of the foregoing circumstances occurs, a holder may convert its Convertible Notes, in multiples of $1,000 principal amount, at any time on or after December 1, 2019 until maturity.

In addition, if we undergo a fundamental change (as defined in the indenture governing the Convertible Notes), holders may, subject to certain conditions, require us to repurchase their Convertible Notes for cash at a price equal to 100% of the principal amount of the Convertible Notes to be purchased, plus any accrued and unpaid interest. In addition, if specific corporate events occur prior to the maturity date, we will increase the conversion rate for a holder who elects to convert its Convertible Notes in connection with such a corporate event in certain circumstances.

In connection with the issuance of the Convertible Notes, we paid approximately $140 million to enter into prepaid forward stock repurchase transactions (the “Forward Transactions”) with certain financial institutions (the “Forward Counterparties”), pursuant to which we purchased approximately 7.2 million shares of common stock for settlement on or around the March 1, 2020 maturity date for the Convertible Notes, subject to the ability of each Forward Counterparty to elect to settle all or a portion of its Forward Transactions early. As a result of the Forward Transactions, total shareholders’ equity within our consolidated balance sheet was reduced by approximately $140 million. Approximately 7.2 million shares of common stock that will be effectively repurchased through the Forward Transactions are treated as retired shares for basic and diluted EPS purposes although they remain legally outstanding.

Amended and Restated Senior Term Facility—On July 30, 2014, GIH, Gogo Business Aviation LLC, f/k/a Aircell Business Aviation Services LLC (“GBA”), and Gogo LLC, as borrowers (collectively, the “Borrowers”), entered into an Amendment and Restatement Agreement (the “Amendment”) to the Credit Agreement dated as of June 21, 2012 and amended on April 4, 2013 (the “Amended Senior Term Facility”) among the Borrowers, the lenders named therein, and Morgan Stanley Senior Funding, Inc., as Administrative Agent and Collateral Agent. We refer to the Amendment and the Amended Senior Term Facility collectively as the “Amended and Restated Senior Term Facility.”

Prior to the Amendment, under the Amended Senior Term Facility we borrowed an aggregate principal amount of $248.0 million (the “Tranche B-1 Loans”). Pursuant to the Amendment, we borrowed an aggregate additional principal amount of $75.0 million (the “Tranche B-2 Loans” and, together with the Tranche B-1 Loans, the “Loans”).

The interest rates applicable to the Tranche B-1 Loans were based on a fluctuating rate of interest measured by reference, at GBA’s option, to either (i) a London inter-bank offered rate adjusted for statutory reserve requirements (“LIBOR”) (subject to a 1.50% floor) plus an applicable margin of 9.75% per annum, or (ii) an alternate base rate (“Base Rate”) (subject to a 2.50% floor) plus an applicable margin of 8.75% per annum. The interest rates applicable to the Tranche B-2 Loans were based on a fluctuating rate of interest measured by reference, at GBA’s option, to either (i) LIBOR (subject to a 1.00% floor) plus an applicable margin of 6.50% per annum, or (ii) a Base Rate (subject to a 2.00% floor) plus an applicable margin of 5.50% per annum. Immediately prior to the termination, all loans were outstanding as one month LIBOR loans, and the interest rates on the Tranche B-1 Loans and the Tranche B-2 Loans were 11.25% and 7.50%, respectively. We paid customary fees in respect of the Amended and Restated Senior Term Facility.

The Tranche B-2 Loans were secured by the same collateral and guaranteed by the same guarantors as the Tranche B-1 Loans. The call premiums, mandatory prepayments, covenants, events of default and other terms applicable to the Tranche B-2 Loans were also generally the same as the corresponding terms applicable to the Tranche B-1 Loans under the Amended and Restated Senior Term Facility.

On June 14, 2016 the outstanding principal balance of $287.7 million, together with accrued and unpaid interest, was paid in full, and the Amended and Restated Senior Term Facility was terminated in accordance with its terms on such date (subject to the survival of provisions expressly stated therein to survive the termination thereof). Additionally, we paid the voluntary prepayment premium of 3.0% or $8.6 million and wrote off all of the remaining unamortized deferred financing costs of $6.8 million. Both of these items are included in loss on extinguishment of debt in our consolidated financial statements. As of December 31, 2015, $301.5 million was outstanding under the Amended and Restated Senior Term Facility.

We paid $22.2 million of loan origination fees and financing costs related to the Amended and Restated Senior Term Facility, all but $4.1 million of which were accounted for as deferred financing costs. Total amortization expense of the deferred financing costs was $1.4 million, $3.1 million and $3.2 million, respectively, for the years ended December 31, 2016, 2015 and 2014. Amortization expense is included in interest expense in the consolidated statements of operations. As noted above, deferred financing costs related to the Amended and Restated Senior Term Facility were written off as of June 14, 2016. As of December 31, 2015, the balance of unamortized deferred financing costs related to the Amended and Restated Senior Term Facility was $8.2 million and was included as a reduction to long-term debt in our consolidated balance sheet. See Note 7, “Interest Costs” for additional information.

Alaska Financing—On November 2, 2010, we entered into a $4.1 million standby credit facility agreement (the “Alaska Facility”) with Alaska Airlines, Inc. to finance the construction of ATG network sites in Alaska. The Alaska Facility had a six-year term and an interest rate of 10% per annum, compounded and payable quarterly. In April 2015, we paid in full and terminated the Alaska Facility.

Restricted Cash—Our restricted cash balances were $7.9 million and $7.5 million as of December 31, 2016 and 2015, respectively, which were primarily made up of letters of credit. Certain of the letters of credit require us to maintain restricted cash accounts in a similar amount, and are issued for the benefit of the landlords at our current office locations in Chicago, IL; Bensenville, IL and Broomfield, CO.

Fair Value Disclosures [Abstract]

Fair Value of Financial Assets and Liabilities

9. Fair Value of Financial Assets and Liabilities

A three-tier fair value hierarchy has been established which prioritizes the inputs used in measuring fair value. These tiers include:

•

Level 1—defined as observable inputs such as quoted prices in active markets;

•

Level 2—defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and

•

Level 3—defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

Long-Term Debt:

Our financial assets and liabilities that are disclosed but not measured at fair value include the Senior Secured Notes, the Convertible Notes and the Amended and Restated Senior Term Facility (when outstanding), which are reflected on the consolidated balance sheet at cost. The fair value measurements are classified as Level 2 within the fair value hierarchy since they are based on quoted market prices of our instruments in markets that are not active. We estimated the fair value of the Senior Secured Notes, Convertible Notes and Amended and Restated Senior Term Facility (when outstanding) by calculating the upfront cash payment a market participant would require to assume these obligations. The upfront cash payments used in the calculations of fair value on our December 31, 2016 consolidated balance sheet, excluding any issuance costs, is the amount that a market participant would be able to lend at December 31, 2016 to an entity with a credit rating similar to ours and achieve sufficient cash inflows to cover the scheduled cash outflows under the Senior Secured Notes and the Convertible Notes. The calculated fair value of our Convertible Notes is highly correlated to our stock price and as a result significant changes to our stock price could have a significant impact on the calculated fair value of our Convertible Notes.

The fair value and carrying value of long-term debt as of December 31, 2016 and 2015 was as follows (in thousands):


	December 31, 2016				December 31, 2015

(1)	Fair value amounts are rounded to the nearest million.

(2)	Carrying value of the Convertible Notes excludes unamortized debt discount of $69.9 million and $87.4 million, respectively, as of December 31, 2016 and 2015. See Note 6, “Long-Term Debt and Other Liabilities,” for further information.

We have held-to-maturity financial instruments where carrying value approximated fair value. There were no fair value adjustments to these financial instruments during the years ended December 31, 2016, 2015 and 2014.

Business Segments and Major Customers

10. Business Segments and Major Customers

We operate our business through three operating segments: Commercial Aviation North America, or “CA-NA”, Commercial Aviation Rest of World, or “CA-ROW” and Business Aviation, or “BA”.

CA-NA Segment: Our CA-NA segment provides in-flight connectivity and wireless digital entertainment solutions to commercial airline passengers flying routes that generally begin and end within North America, which for this purpose includes the United States, Canada and Mexico.

CA-ROW Segment: Our CA-ROW business provides in-flight connectivity and wireless digital entertainment solutions to passengers flying on 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) for which our international service is provided.

BA Segment: Our BA business provides equipment for in-flight connectivity along with voice and data services to the business aviation market. BA services include Gogo Biz, our in-flight broadband service that utilizes both our ATG network and our ATG spectrum, Passenger Entertainment, our in-flight entertainment service, and satellite-based voice and data services through strategic alliances with satellite companies. Customers include business aircraft manufacturers, owners, and operators, as well as government and military entities.

The accounting policies of the operating segments are the same as those described in Note 2, “Summary of Significant Accounting Policies”. Intercompany transactions between segments are excluded as they are not included in management’s performance review of the segments. We currently do not generate a material amount of foreign revenue. We do not segregate assets between segments for internal reporting. Therefore, asset-related information has not been presented. We do not disclose assets outside of the United States as we do not believe these assets are material as of December 31, 2016 and 2015. For our airborne assets, we consider only those assets installed in aircraft associated with international commercial airline partners to be owned outside of the United States.

Management evaluates performance and allocates resources to each segment based on segment profit (loss), which is calculated internally as net income (loss) attributable to common stock before interest expense, interest income, income taxes, depreciation and amortization, and certain non-cash charges (including amortization of deferred airborne lease incentives, stock-based compensation expense, adjustment to deferred financing costs and loss on extinguishment of debt). Segment profit (loss) is a measure of performance reported to the chief operating decision maker for purposes of making decisions about allocating resources to the segments and evaluating segment performance. In addition, segment profit (loss) is included herein in conformity with ASC 280-10, Segment Reporting. Management believes that segment profit (loss) provides useful information for analyzing and evaluating the underlying operating results of each segment. However, segment profit (loss) should not be considered in isolation or as a substitute for net income (loss) attributable to common stock or other measures of financial performance prepared in accordance with GAAP. Additionally, our computation of segment profit (loss) may not be comparable to other similarly titled measures computed by other companies.

Stock-Based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-Based Compensation

11. Stock-Based Compensation

As of December 31, 2016, we maintained three stock-based employee compensation plans: the Gogo Inc. 2016 Omnibus Incentive Plan (the “2016 Omnibus Plan”), the Gogo Inc. 2013 Omnibus Incentive Plan (the “2013 Omnibus Plan”), and The Aircell Holdings Inc. Stock Option Plan (the “2010 Plan”), collectively referred to as the “Stock Plans”. Our Stock Plans provide for the grant of both equity and cash awards, including non-qualified stock options, incentive stock options, stock appreciation rights, performance awards (shares and units), restricted stock, restricted stock units (“RSUs”), deferred share units (“DSUs”) and other stock-based awards and dividend equivalents to eligible employees, directors and consultants, as determined by the Compensation Committee of our Board of Directors.

Under the Stock Plans, 20,006,570 shares of common stock were reserved for issuance. As of December 31, 2016, 5,885,574 shares remained available for grant under our Stock Plans.

The contractual life of granted options is 10 years. All options that are unvested as of the date on which a recipient’s employment terminates, as well as vested options that are not exercised within a prescribed period following termination, are forfeited and become available for future grants. Options granted to date include options that a) vest 20% upon grant with the remainder vesting in equal annual increments over a four-year period, b) vest over a four-year period with 25% vesting at the end of each year or c) vest on the date of grant for options granted to directors. Beginning in 2013 we granted RSUs that vest in equal annual increments over a four-year period. Vested RSUs will be settled, at the discretion of the Compensation Committee, in shares of our common stock or in cash equal to the value of the applicable number of shares of our common stock on the vesting date. We also granted directors DSUs that were vested at grant. DSUs will be settled in shares of our common stock 90 days after the director ceases to serve as a director. Beginning in 2014 we granted restricted stock, which vests in equal annual increments over a four-year period. These shares are deemed issued as of the date of grant, but not outstanding until they vest. We intend to settle RSU, DSU and restricted stock awards in stock and have the shares available to do so. In June 2016, the Compensation Committee approved grants of both non-market based awards and market based awards. The contractual term and time-based vesting provisions for the non-market based awards are consistent with prior grants as noted above. The market based awards vest based on achieving one or more predetermined market conditions and completion of the same time-based vesting requirements applicable to the non-market based awards.

The following is a summary of our stock-based compensation expense included in the consolidated statements of operations for the years December 31, 2016, 2015 and 2014 (in thousands):


	2016		2015		2014
Cost of service revenue	$	1,499	$	1,161	$	673
Cost of equipment revenue		117		86		31

Sales and marketing		4,962		4,107		1,618
General and administrative		7,997		7,361		5,825

Total stock-based compensation expense	$	17,621	$	15,299	$	9,816

A summary of stock option activity for the year ended December 31, 2016, is as follows:


	Number of Options			Weighted Average Exercise Price Per Share		Weighted Average Remaining Contractual Life		Aggregate Intrinsic Value (in thousands)
Options outstanding—January 1, 2016		7,236,539		$	16.23		7.07	$	17,210
Granted		2,138,435		$	8.67
Exercised		(12,150	)	$	9.08
Forfeited		(157,853	)	$	14.48
Expired		(70,529	)	$	16.89

Options outstanding—December 31, 2016		9,134,442		$	14.50		6.81	$	1,789

Options exercisable—December 31, 2016		5,237,705		$	14.76		5.46	$	312

There were no stock options exercised prior to 2013. As of December 31, 2016, total unrecognized compensation costs related to unvested stock options were approximately $17 million which is expected to be recognized over a weighted average period of approximately 2.6 years. The total grant date fair value of stock options vested in 2016, 2015 and 2014 was approximately $9.0 million, $8.0 million and $6.0 million, respectively.

We estimate the fair value of stock options using the Black-Scholes option-pricing model. Weighted average assumptions used and weighted average grant date fair value of stock options granted for the years ended December 31, 2016, 2015, and 2014, were as follows:


	2016			2015			2014
Approximate risk-free interest rate		1.3	%		1.8	%		1.9	%
Average expected life (years)		6.12			6.17			6.20
Dividend yield		N/A			N/A			N/A
Volatility		45.3	%		33.1	%		43.5	%
Weighted average grant date fair value of common stock underlying options granted	$	8.72		$	20.65		$	17.67
Weighted average grant date fair value of stock options granted	$	3.88		$	7.39		$	7.88

The risk-free interest rate assumptions were based on the U.S. Treasury yield curve for the term that mirrored the expected term in effect at the time of grant. The expected life of our stock options was determined based upon a simplified assumption that the stock options will be exercised evenly from vesting to expiration, as we do not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected life. The dividend yield was based on expected dividends at the time of grant. We have not been a public company long enough to calculate volatility based exclusively on our own common stock. Therefore, the expected volatility is calculated as of each grant date based on a weighting of our own common stock and reported data for a peer group of publicly traded companies for which historical information is available.

The following table summarizes the activities for our unvested RSUs and DSUs for the year ended December 31, 2016:


	Number of Underlying Shares			Weighted Average Grant Date Fair Value
Unvested—January 1, 2016		974,989		$	19.55
Granted		1,007,567		$	8.07
Vested		(351,239	)	$	17.26
Forfeited/canceled		(134,269	)	$	14.77

Unvested—December 31, 2016		1,497,048		$	12.81

As of December 31, 2016, there was approximately $16 million of unrecognized compensation cost related to unvested employee RSUs. This amount is expected to be recognized over a weighted-average period of approximately 2.7 years. The total grant date fair value of RSUs and DSUs vested in 2016 was approximately $6 million.

The following table summarizes the activity for our restricted stock for the year ended December 31, 2016:


	Number of Underlying Shares			Weighted Average Grant Date Fair Value
Unvested—January 1, 2016		213,585		$	19.00
Granted		127,200		$	8.89
Vested		(64,113	)	$	18.78
Forfeited/canceled		(42,700	)	$	15.19

Unvested—December 31, 2016		233,972		$	14.26

As of December 31, 2016, there was approximately $2.5 million of unrecognized compensation cost related to unvested employee restricted stock. This amount is expected to be recognized over a weighted-average period of approximately 2.3 years.

ESPP—In June 2013 the Board of Directors and stockholders approved the Employee Stock Purchase Plan (“ESPP”), which became effective on June 26, 2013. The ESPP allows eligible employees to purchase a limited number of shares of common stock during pre-specified offering periods at a discount established by the Compensation Committee not to exceed 15% of the fair market value of the common stock at the beginning or end of the offering period (whichever is lower). Under the ESPP, 424,594 shares were reserved for issuance and 143,085 shares of common stock were issued during the year ended December 31, 2016.

Net deferred income tax liability	$	(8,264	)	$	(7,425	)

We assess the realizability of the deferred tax assets by considering whether it is more likely than not that some portion or all of the deferred tax assets would not be realized through the generation of future taxable income. We generated net losses in fiscal years 2016, 2015, and 2014, which means we are in a domestic three-year cumulative loss position. As a result of this and other assessments in fiscal 2016, we concluded that a full valuation allowance is required for all deferred tax assets and liabilities except for deferred tax liabilities associated with indefinite-lived intangible assets.

As of December 31, 2016, the federal net operating loss (“NOL”) carryforward amount was approximately $347 million and the state NOL carryforward amount was approximately $228 million. The federal NOLs begin to expire in 2031. The state NOLs expire in various tax years and began to expire in 2016.

Utilization of our NOL and tax credit carryforwards may be subject to substantial annual limitations due to the ownership change limitations provided by the Internal Revenue Code and similar state provisions. Such annual limitations could result in the expiration of the NOL and tax credit carryforwards before their utilization. The events that may cause ownership changes include, but are not limited to, a cumulative stock ownership change of greater than 50% over a three-year period.

We are subject to taxation in the United States, various states, Canada, Switzerland, Japan, Mexico, Brazil, Singapore, the United Kingdom, Hong Kong and Australia. With few exceptions, as of December 31, 2016, we are no longer subject to U.S. federal, state, local or foreign examinations by tax authorities for years before 2013.

As of December 31, 2016, 2015 and 2014, we did not have any unrecognized tax benefits.

We record penalties and interest relating to uncertain tax positions in the income tax provision line item in the consolidated statement of operations. No penalties or interest related to uncertain tax positions were recorded for the years ended December 31, 2016, 2015 or 2014. As of December 31, 2016 and 2015, we did not have a liability recorded for interest or potential penalties.

We do not expect there will be a change in the unrecognized tax benefits within the next 12 months.

14. Leases

Arrangements with Commercial Airlines—Pursuant to contractual agreements with our airline partners, we place our equipment on commercial aircraft operated by the airlines for the purpose of delivering our service to passengers on the aircraft. Depending on the agreement, we may be responsible for the costs of installing and/or deinstalling the equipment. Under one type of connectivity agreement we maintain legal title to our equipment; however, under a second, more prevalent type of connectivity agreement some of our airline partners make an upfront payment and take legal title to such equipment. The majority of the equipment transactions involve the transfer of legal title but have not met sales recognition for accounting purposes because the risks and rewards of ownership are not fully transferred due to our continuing involvement with the equipment, the length of the term of our agreements with the airlines, and restrictions in the agreements regarding the airlines’ use of the equipment. We account for these equipment transactions as operating leases of space for our equipment on the aircraft. The assets are recorded as airborne equipment on our consolidated balance sheets, as noted in Note 4, “Composition of Certain Balance Sheet Accounts.” Any upfront equipment payments are accounted for as lease incentives and recorded as deferred airborne lease incentives on our consolidated balance sheets and are recognized as a reduction of the cost of service revenue on a straight-line basis over the term of the agreement with the airline. We recognized $29.5 million, $20.2 million and $12.8 million for the years ended December 31, 2016, 2015 and 2014, respectively, as a reduction to our cost of service revenue in our consolidated statements of operations. As of December 31, 2016, deferred airborne lease incentives of $36.3 million and $135.9 million are included in current and non-current liabilities, respectively, in our consolidated balance sheet. As of December 31, 2015, deferred airborne lease incentives of $21.7 million and $121.7 million are included in current and non-current liabilities, respectively, in our consolidated balance sheet.

The revenue share paid to our airline partners represent operating lease payments and are deemed to be contingent rental payments, as the payments due to each airline are based on a percentage of our CA-NA and CA-ROW service revenue generated from that airline’s passengers, which is unknown until realized. Therefore, we cannot estimate the lease payments due to an airline at the commencement of our contract with such airline. Rental expense related to the arrangements with commercial airlines included in cost of service revenue is primarily comprised of these revenue share payments offset by the amortization of the deferred airborne lease incentives discussed above. Such rental expenses totaled a net charge of $41.6 million, $40.6 million and $40.3 million, respectively, for the years ended December 31, 2016, 2015 and 2014.

One contract with one of our airline partners requires us to provide our airline partner with cash rebates of $1.8 million in June 2017 and June 2018.

Leases and Cell Site Contracts—We have lease agreements relating to certain facilities and equipment, which are considered operating leases. Rent expense for such operating leases was $11.8 million, $15.3 million and $10.8 million, respectively, for the years ended December 31, 2016, 2015 and 2014. Additionally, we have operating leases with wireless service providers for tower space and base station capacity on a volume usage basis (“cell site leases”), some of which provide for minimum annual payments. Our cell site leases generally provide for an initial noncancelable term with various renewal options. Total cell site rental expense was $9.4 million, $9.4 million and $8.7 million, respectively, for the years ended December 31, 2016, 2015 and 2014.

Annual future minimum obligations for operating leases for each of the next five years and thereafter, other than the arrangements we have with our commercial airline partners, as of December 31 2016, are as follows (in thousands):

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	15. Commitments and Contingencies Contractual Commitments—We have agreements with vendors to provide us with transponder and teleport satellite services. These agreements vary in length and amount and as of December 31, 2016 commit us to purchase transponder and teleport satellite services totaling approximately $61.9 million in 2017, $46.9 million in 2018, $49.2 million in 2019, $62.2 million in 2020, $61.7 million in 2021 and $284.2 million thereafter. We have agreements with various vendors under which we have remaining commitments to purchase satellite-based systems, certifications and development services. Such commitments will become payable as we receive the equipment or certifications, or as development services are provided. Damages and Penalties—We have entered into a number of agreements with our airline partners that require us to provide a credit or pay liquidated damages to our airline partners on a per aircraft, per day or per hour basis if we are delayed in delivering our equipment, unable to install our equipment on aircraft by specified timelines or fail to comply with service level commitments. The maximum amount of future credits or payments we could be required to make under these agreements is uncertain because the amount of future credits or payments is based on certain variable inputs. Indemnifications and Guarantees—In accordance with Delaware law, we indemnify our officers and directors for certain events or occurrences while the officer or director is, or was, serving at our request in such capacity. The maximum potential amount of future payments we could be required to make under this indemnification is uncertain and may be unlimited, depending upon circumstances. However, our Directors’ and Officers’ insurance does provide coverage for certain of these losses. In the ordinary course of business we may occasionally enter into agreements pursuant to which we may be obligated to pay for the failure of performance of others, such as the use of corporate credit cards issued to employees. Based on historical experience, we believe that the risk of sustaining any material loss related to such guarantees is remote. We have entered into a number of agreements, including our agreements with commercial airlines, pursuant to which we indemnify the other party for losses and expenses suffered or incurred in connection with any patent, copyright, or trademark infringement or misappropriation claim asserted by a third party with respect to our equipment or services. The maximum potential amount of future payments we could be required to make under these indemnification agreements is uncertain and is typically not limited by the terms of the agreements. Salameno Litigation—On January 29, 2016, Charles Salameno, Maria-Angela Sanzone and John Jensen filed suit against us in the United States District Court for the Eastern District of New York, on behalf of a putative class of national purchasers and a subclass of New York purchasers of our connectivity service, alleging that we violated New York and other consumer protection laws, as well as unjust enrichment, fraud and breach of contract arising from alleged false statements in our marketing materials and alleged data security issues arising from our network design and certain network practices. The suit seeks unspecified damages. On May 23, 2016, we filed motions to compel arbitration and dismiss the suit, moving in the alternative to transfer venue and/or dismiss the suit for failure to state a claim. The Court held a hearing on June 30, 2016 where we argued the motions to dismiss and on July 7, 2016 the Court issued its opinion granting our motion to compel arbitration. On August 1, 2016, the Plaintiffs filed a motion asking the Court to reconsider its decision to compel arbitration. On September 15, 2016, the Court denied Plaintiffs’ motion for reconsideration. On October 14, 2016, Plaintiffs filed a Notice of Appeal with the U.S. Court of Appeals for the Second Circuit. Plaintiffs’ withdrew their appeal with prejudice on November 4, 2016, concluding the Salameno class action. Plaintiffs’ have the right to pursue their claims individually in arbitration.

Canadian ATG Spectrum License

16. Canadian ATG Spectrum License

On July 17, 2012, Industry Canada issued to our Canadian subsidiary a subordinate license that allows us to use the Canadian ATG spectrum of which SkySurf Canada Communications Inc. (“SkySurf”) is the primary licensee. On July 24, 2012 we entered into a subordinate license agreement (the “License Agreement”) with SkySurf and on August 14, 2012 the agreement commenced. The License Agreement provides for our exclusive rights to use SkySurf’s ATG spectrum licenses in Canada. The License Agreement has an initial term of ten years commencing on August 14, 2012 and, provided that the primary spectrum license agreement issued by Industry Canada to SkySurf remains in effect, is renewable at our option for an additional ten-year term following the initial expiration and thereafter for a further five-year term. We made a one-time payment of C$3.3 million, which was equivalent to approximately U.S. $3.3 million (“one-time payment”). The renewal of the primary spectrum license will depend upon the satisfaction by Gogo and SkySurf of certain conditions set forth in the license, including, without limitation, a network build-out requirement. The term of the License Agreement, including the initial ten-year term and any renewals, is contingent on the effectiveness and renewal of the primary spectrum license issued by Industry Canada to SkySurf on June 30, 2009, which expires on June 29, 2019. We pay SkySurf C$0.1 million, which is equivalent to U.S. $0.1 million, monthly during the initial ten-year term of the License Agreement. Additionally, we make variable monthly payments based on the number of cell sites in Canada and the number of Canadian-domiciled commercial aircraft on which we provide our service.

As the License Agreement is for our exclusive use of a license, which is considered a right to use an intangible asset and thus not property, plant, or equipment, the agreement is not considered a lease for accounting purposes. As such, we recorded the SkySurf one-time payment as an asset in our consolidated balance sheet at the time of payment. As of December 31, 2016 and 2015 the one-time payment had balances of $0.1 million and $0.1 million included in prepaid expenses and other current assets, respectively, and $1.9 million and $1.9 million included in other non-current assets, respectively, in our consolidated balance sheet. The one-time payment is being amortized on a straight-line basis over the estimated term of the agreement of 25-years, which includes estimated renewal periods.

Amortization expense for the one-time payment for each of the next five years and thereafter is estimated to be as follows (in thousands):


Years ending December 31,	Canadian ATG Spectrum Amortization
2017	$	97
2018	$	97
2019	$	97
2020	$	97
2021	$	97
Thereafter	$	1,505

Amortization expense totaled $0.1 million for the years ended December 31, 2016, 2015 and 2014.

The monthly payments are expensed as incurred and totaled approximately $1.2 million, $1.1 million and $1.1 million for the years ended December 31, 2016, 2015 and 2014, respectively.

The Additional Notes were issued at a price equal to 108% of their face value resulting in gross proceeds of $70.2 million. We intend to use the net proceeds from the issuance of the Additional Notes for working capital and other general corporate purposes. The Additional Notes have the same terms as the original Senior Secured Notes, except with respect to the issue date and issue price and are treated as a single series for all purposes under the Indenture and the security documents that govern the Additional Notes and the original Senior Secured Notes. We paid approximately $2.0 million of loan origination fees and financing costs related to the issuance of the Additional Notes, which has been accounted for as deferred financing costs. The deferred financing costs will be amortized over the contractual term of the Senior Secured Notes using the effective interest method. On February 24, 2017, Gogo LLC, an indirect wholly-owned subsidiary of Gogo Inc., entered into a Unified In-Flight Connectivity Hardware, Services and Maintenance Agreement with American Airlines, which replaces and supersedes the Third Amended and Restated In Flight Connectivity Services Agreement between American Airlines and Gogo LLC, the In Flight Connectivity Services Agreement between American Airlines and Gogo LLC, the Amended and Restated In Flight Connectivity Services Agreement between US Airways and Gogo LLC and the Letter Agreement between Gogo LLC and American Airlines.
