Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

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

We are 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 share-based compensation plan (see Note 11, “Share-Based Compensation,” for further information). Since we are the managing member of ACM and thereby control ACM, including controlling which members of management are 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.

Reclassifications—In order to conform to the current year presentation, deferred rent for the 2013 and 2012 consolidated statements of cash flows has been reclassified to be presented as a separate line item. Specifically, in prior years deferred rent of $20 and $24 for the years ended December 31, 2013 and 2012, respectively, had been included in accrued liabilities and deferred rent of ($43) and $515 for the years ended December 31, 2013 and 2012, respectively, had been included in other non-current assets and liabilities in our consolidated statements of cash flows.

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 suppliers and distributors, financing arrangement terms that may restrict operations, regulatory issues, competition, the economy, technology trends, and evolving industry standards.

Cash and Cash Equivalents—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 that have 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.

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 and accounts receivable. All cash and cash equivalents are invested in creditworthy financial institutions. We perform ongoing credit evaluations and generally do not require collateral to support receivables.

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 includes 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, radomes, antennas and related equipment, and accessories installed or to be installed on aircraft. Depreciation expense totaled $53.4 million, $46.3 million and $29.5 million for the years ended December 31, 2014, 2013, and 2012, 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. We perform our annual impairment tests of goodwill and our indefinite-lived intangible assets during the fourth quarter of each fiscal year. We assess the fair value of our FCC licenses using the Greenfield method, an income-based approach. Under the income approach, the fair value of the intangible asset is based on the present value of estimated future cash flows.

In performing our annual review of goodwill and indefinite-lived intangible asset balances for impairment, we estimate the fair value 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 2014, 2013, and 2012 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
Trademark/trade name			5 years
Aircell Axxess technology			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.

Arrangements with Commercial Airlines—Pursuant to connectivity agreements with our airline partners, we place our equipment on commercial aircraft operated by the airlines for the purpose of delivering the Gogo^® service to passengers on the aircraft. Depending on the agreement, we may be responsible for the costs of installing and 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 our airline partners make an upfront payment and take legal title to such equipment. The majority of the equipment transactions where legal title transfers are not deemed to be sales transactions 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.

Our contracts with each commercial airline also require us 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, multiple access packages (“multi-packs”) and an unlimited monthly access option. Under the multi-packs, revenue is deferred and recognized each time the customer accesses the network. Upon expiration, any amounts that are not used are recognized as revenue. 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 evenly 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 also derives service revenue under arrangements with various third parties who sponsor free or discounted access to Gogo^® 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. Due to the short-term nature of these arrangements, all deferred amounts related to our sponsorships are classified as current liabilities in our consolidated balance sheets. Other sources of CA-NA revenue include fees paid by third parties to advertise on or to enable ecommerce transactions through our airborne portal. For advertising or ecommerce 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 megabyte (“MB”) usage for airline operational applications. Under these arrangements, fixed-fee revenue (contractual allowance of MB’s) 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 have transferred to the customer, we have no future obligations for installation or maintenance service, the price is fixed or determinable, and collectability is reasonably assured.

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.

Our BA segment has multi-element arrangements that include both equipment and service revenue. Revenue is allocated to each element based on the relative fair value 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 the price charged when each element is sold separately, or vendor-specific objective evidence (“VSOE”). We use VSOE to determine the fair value of the elements pertaining to this arrangement.

Our CA-ROW business is in the start-up phase. In March 2014, we generated our first CA-ROW in-flight connectivity revenue and for the years ended December 31, 2014, 2013 and 2012 has generated minimal revenue. Additionally CA-ROW generates revenue from monthly service fees charged to our airline partners for network monitoring and portal management services. We recognize these monthly fees as the services are provided and billed to the airlines.

Research and Development Costs—Expenditures for research and development are charged to expense as incurred and totaled $36.9 million, $29.8 million and $23.6 million for the years ended December 31, 2014, 2013, and 2012, 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—Our BA segment provides 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—Prior to the IPO, our Class A Senior Convertible Preferred Stock (“Class A Preferred Stock”) and Junior Convertible Preferred Stock (“Junior Preferred Stock”) contained features that were considered embedded derivatives and were required to be bifurcated from the preferred stock and accounted for separately. These embedded derivatives were recognized in our consolidated balance sheets at fair value and the changes in fair values were recognized as noncash activity in earnings each period.

See Note 8, “Common Stock and Preferred Stock,” and Note 9, “Fair Value of Financial Assets and Liabilities,” for further information.

Preferred Stock—Prior to the IPO, we elected to accrete changes in the redemption value of our preferred stock over the period from the date of issuance to the earliest redemption date using the effective interest method.

See Note 8, “Common Stock and Preferred Stock,” 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.

Share-Based Compensation—Compensation cost is measured and recognized at fair value for all share-based payments, including stock options. For 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. Our share-based compensation expense is recognized net of estimated forfeitures on a straight-line basis over the applicable vesting period, and is included in general and administrative expenses in our consolidated statements of operations. For 2014, 2013, and 2012, we estimated a forfeiture rate when computing share-based compensation expense. We reassess our estimated forfeiture rate periodically based on new facts and circumstances.

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

Additional Paid-in Capital—For our internal recordkeeping, we categorized our additional paid-in capital account into two categories: additional paid-in capital related to equity share issuances and additional paid-in capital related to share-based compensation. Preferred stock return and accretion of preferred stock were historically recorded as reductions to additional paid-in capital related to equity share issuances. In 2012, due to the level of preferred stock return and accretion of preferred stock recognized, the balance of our additional paid-in capital related to equity share issuances was reduced to zero. Accordingly, during 2013 and 2012 we recorded preferred stock return and accretion of preferred stock as increases to our accumulated deficit. See our consolidated statements of stockholders’ equity (deficit) for further information.

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 lease the 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 deferred loan origination fees and financing costs related to the Amended and Restated Senior Term Facility (as defined in Note 6, “Long-Term Debt and Other Liabilities”), all of which have been accounted for as deferred financing costs. Additionally, we deferred fees paid directly to the lenders related to the amendments to the Amended and Restated Senior Term Facility (as defined in Note 6, “Long-Term Debt and Other Liabilities”) as deferred financing costs. We amortize these costs over the term of the Amended and Restated Senior Term Facility (as defined in Note 6, “Long-Term Debt and Other Liabilities”) 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 the amendments were expensed to interest expense.

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

Comprehensive Income (Loss)—Comprehensive loss for the years ended December 31, 2014, 2013 and 2012 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. We will adopt this guidance as of January 1, 2017. We are currently evaluating the impact of the adoption of this guidance on our financial position, results of operations and cash flows.

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 implementing requirements for management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. We will adopt this guidance as of January 1, 2017. We do not anticipate that the adoption of this guidance will result in additional disclosures, however, management will begin performing the periodic assessments required by ASU 2014-15 on its effective date.

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. Prior to our IPO, the three classes of then outstanding preferred stock were all considered participating securities requiring the two-class method to calculate basic and diluted earnings per share. In periods of a net loss attributable to common stock, the three classes of preferred stock were excluded from the computation of basic earnings per share either due to the fact that they were not required to fund losses or because the redemption amount was not reduced as a result of losses.

As a result of the net loss for each of the years ended December 31, 2014, 2013 and 2012 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, restricted stock units and preferred stock 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, 2014, 2013 and 2012. Prior to our IPO, we made this computation using the two-class method; however, because of the undistributed losses the three classes of our pre-IPO preferred stock are excluded from the computation of basic earnings per share as undistributed losses are not allocated to preferred 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 2014, 2013, and 2012 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.

As of December 31, 2014 and 2013, our goodwill balance, all of which related to our BA segment, was $0.6 million.

Our intangible assets, other than goodwill, as of December 31, 2014 and 2013 were as follows (in thousands, except for weighted average remaining useful life):

Long-Term Debt and Other Liabilities

6. Long-Term Debt and Other Liabilities

Senior Debt—On July 30, 2014, Gogo Intermediate Holdings LLC, Gogo Business Aviation LLC, f/k/a Aircell Business Aviation Services LLC (“GBA”), and Gogo LLC, as borrowers (the “Borrowers”), entered into an Amendment and Restatement Agreement (the “Amendment”) to the Credit Agreement dated as of June 21, 2012 as 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”). We received net cash proceeds from the Tranche B-2 Loans of $72.4 million following the payment of debt issuance fees of $2.6 million. We are using the proceeds from the Tranche B-2 Loans for general corporate purposes. As of December 31, 2014 and 2013, we had $309.2 million and $240.8 million outstanding under the Amended and Restated Senior Term Facility, respectively.

GIH, Gogo LLC and GBA are the borrowers under the Amended and Restated Senior Term Facility. The obligations of the borrowers under the Amended and Restated Senior Term Facility are guaranteed by each of our direct and indirect wholly-owned domestic subsidiaries, in each case to the extent otherwise permitted by applicable law, regulation and contractual provision. In addition, the Amended and Restated Senior Term Facility and the guarantees thereunder are secured by security interests in (i) all of the capital stock of all direct domestic subsidiaries owned by the borrowers and the guarantors, (ii) 65% of the capital stock of each direct foreign subsidiary owned by any borrower or any guarantor (foreign subsidiary holding companies are deemed to be foreign subsidiaries), and (iii) substantially all other tangible and intangible assets (including intellectual property) of the borrowers and the guarantors, subject in each case to certain exceptions.

The Amended and Restated Senior Term Facility contains customary representations and warranties, affirmative and negative covenants, and events of default. If an event of default occurs and so long as such event of default is continuing, the amounts outstanding will accrue interest at an increased rate and payments of such outstanding amounts could be accelerated. We do not have maintenance covenants under the terms of the Amended and Restated Senior Term Facility but as part of its affirmative covenants, we need to maintain a minimum cash balance of $5.0 million and comply with certain reporting and notice requirements and periodic financial statement reporting on a borrowing entity basis. As of December 31, 2014, we were in compliance with the covenants, cash balance, reporting and notice requirements of the Amended and Restated Senior Term Facility and no event of default had occurred.

The Amended and Restated Senior Term Facility contains covenants that, among other things, limit or restrict the ability of the borrowers and the guarantors to dispose of assets, incur or guarantee additional indebtedness, prepay certain subordinated indebtedness, modify certain terms of certain material agreements (including intercompany agreements), make dividends and other restricted payments, issue additional preferred stock, make investments (including a cap on investments in our international business during the term of the Amended and Restated Senior Term Facility), incur or maintain liens, make capital expenditures, engage in mergers and certain other fundamental changes, engage in certain transactions with affiliates, enter into sale-leaseback arrangements or enter into agreements restricting dividends or other distributions by subsidiaries to the borrowers or any of their subsidiaries. As of December 31, 2014, these covenants restricted the borrowers from distributing $91 million of their net assets to our Parent Company, Gogo Inc.

In connection with the Amendment, the maturity date of the Amended and Restated Senior Term Facility was extended to March 21, 2018. Principal payments of $1.7 million are due on the last day of each calendar quarter through December 31, 2017, with the remaining unpaid principal amount due and payable at maturity on March 21, 2018.

The interest rates applicable to the Tranche B-1 Loans are 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 are 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. As of December 31, 2014, all loans were outstanding as three 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 will pay customary fees in respect of the Amended and Restated Senior Term Facility.

The Tranche B-2 Loans are 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 are also generally the same as the corresponding terms applicable to the Tranche B-1 Loans under the Amended and Restated Senior Term Facility.

We paid $19.6 million of loan origination fees and financing costs related to the Amended Senior Term Facility, all but $3.0 million of which have been accounted for as deferred financing costs. The $3.0 million of fees that were not accounted for as deferred financing costs were fees incurred but not paid directly to the lenders in connection with the amendment in April 2013 and were expensed to interest expense. We paid $2.6 million of loan origination fees and financing costs related to the Amendment executed in July 2014, all but $1.1 million of which have been accounted for as deferred financing costs. The $1.1 million of fees that were not accounted for as deferred financing costs were fees incurred but not paid directly to the lenders in connection with the Amendment in July 2014 and were expensed as interest expense. See Note 7, “Interest Costs,” for additional details. Total amortization expense of the deferred financing costs was $3.2 million, $2.8 million and $0.8 million for the years ended December 31, 2014, 2013 and 2012, respectively. Amortization expense is included in interest expense in the consolidated statements of operations. As of December 31, 2014 and 2013, the balance of unamortized deferred financing costs related to the Amended and Restated Senior Term Facility was $11.3 million and $13.0 million, respectively, which was included as a separate line in our consolidated balance sheets.

Principal payments under the Amended and Restated Senior Term Facility for each of the next five years and thereafter are as follows (in thousands):


Years ending December 31,	Credit Facility
2015	$	7,826
2016	$	6,950
2017	$	6,950
2018	$	287,518

The credit agreement executed in connection with our Amended and Restated Senior Term Facility provides for mandatory prepayments and the ability to make optional prepayments. Based on historical and current expectations regarding cash flow generation, the credit agreement was structured to provide that any mandatory prepayments will be calculated based on the excess cash flows (as defined in the credit agreement) of GBA only. This calculation is made at the end of each fiscal year, with any required payments due no later than the 95^th day following the end of the applicable fiscal year, and is based on GBA’s debt leverage ratio. A leverage ratio of 3.25x or higher will trigger a mandatory prepayment of 50% of excess cash flows for the year, a leverage ratio of 2.0x or higher but less than 3.25x will trigger a mandatory prepayment of 25% of excess cash flows for the year and a leverage ratio of less than 2.0x will not trigger any mandatory prepayment of excess cash flows. The amount of any required mandatory prepayments will be reduced by the amount of any optional prepayments made during the applicable fiscal year. As of December 31, 2014 we calculated a mandatory prepayment of approximately $0.9 million which is included in current liabilities in our consolidated balance sheet.

We may voluntarily prepay the loans subject to conditions, prices and premiums as follows:

(i)

On and prior to December 21, 2015, we may prepay the loans at par plus (a) 3.0% of the principal amount of the loans prepaid and (b) a “make whole” premium based on a discounted present value of the interest and principal payments due on such prepaid loans through December 21, 2015;

(ii)

After December 21, 2015 but prior to December 21, 2016, we may prepay the loans at par plus 3.0% of the principal amount of loans prepaid;

(iii)

On and after December 21, 2016, we may prepay the loans at par.

Alaska Financing—On November 2, 2010, we entered into a $4.1 million standby credit facility agreement (the “Alaska Facility”) with Alaska Airlines, Inc. (“Alaska Airlines”) to finance the construction of ATG network sites in Alaska. The Alaska Facility has a six-year term and an interest rate of 10% per annum, compounded and payable quarterly. As of December 31, 2014 and 2013, we had $1.0 million and $1.5 million, respectively, outstanding under the Alaska Facility. No further draws can be made under the Alaska Facility and principal amounts outstanding are payable in quarterly installments until its maturity on November 12, 2016, or can be prepaid at any time without premium or penalty at our option. The Alaska Facility is secured by a first-priority interest in our cell tower leases and other personal property located at the cell sites in Alaska.

The Alaska Facility contains representations and warranties and affirmative and negative covenants customary for financings of this type. There are no financial covenants; however, other covenants include limitations on liens on the collateral assets as well as mergers, consolidations, and similar fundamental corporate events, and a requirement that we continue as the in-flight connectivity service provider to Alaska Airlines.

Pursuant to our equipment and revenue agreement with Alaska Airlines, the share of service revenue (“revenue share”) we pay Alaska Airlines increases as long as any amounts are outstanding under the Alaska Facility. Alaska Airlines revenue share increases by 300 basis points for service revenue generated on flights that use the ATG network in Alaska, until the principal and all accrued interest is paid in full. This incremental revenue share was less than $0.1 million for the years ended December 31, 2014, 2013 and 2012 and is included in our consolidated statements of operations as part of our interest expense.

Principal payments under the Alaska Facility in each of the next five years and thereafter are as follows (in thousands):

Interest Costs

7. Interest Costs

We capitalize a portion of our interest on funds borrowed during the active construction period of major capital projects. Capitalized interest is added to the cost of the underlying assets and amortized over the useful lives of the assets. We commenced capitalizing interest on major capital projects when we entered into the Senior Term Facility on June 21, 2012.

The following is a summary of our interest costs for the years ended December 31, 2014, 2013 and 2012 (in thousands):

Common Stock and Preferred Stock

8. Common Stock and Preferred Stock

Common Stock—We have one class of common stock outstanding as of December 31, 2014 and 2013. Our common stock is junior to our preferred stock, if and when issued. See “Post IPO Preferred Stock” below for additional information.

Our Third Amended and Restated Certificate of Incorporation authorizes a total of 500,000,000 shares of common stock with a par value of $0.0001 per share.

On June 20, 2013, we priced our IPO of 11,000,000 shares of common stock and such shares began trading on the NASDAQ Global Select Market on June 21, 2013. The public offering price of the shares sold in the offering was $17.00 per share. Upon consummation of the IPO, all of the then outstanding shares of convertible preferred stock converted into 66,235,473 shares of common stock, which includes 2,135,602 common shares issued in connection with the liquidation preference associated with our Class A Preferred Stock.

On December 23, 2011 we filed our initial registration statement to commence our initial public offering process. In the fourth quarter of 2012, primarily due to market conditions, we temporarily suspended our efforts to conduct an initial public offering and accordingly in 2012 wrote-off $5.0 million of deferred equity financing costs incurred through December 31, 2012.

Post IPO Preferred Stock—Effective upon the closing of the IPO in June 2013, our previously issued preferred stock was no longer outstanding as all such preferred stock was converted into common stock.

Our Third Amended and Restated Certificate of Incorporation authorizes 100,000,000 shares of new preferred stock with a par value of $0.01 per share. No shares of this new preferred stock have been issued. The preferred stock may be issued, from time to time, in one or more series as authorized by the Board of Directors, which has the authority to designate the terms of any series of preferred stock issued, including, without limitation, the number of shares to be included in the series of preferred stock, any dividend, redemption, conversion rights or voting powers and the designations, preferences and relative participating, optional or other special rights.

Pre IPO Preferred Stock—Prior to our IPO, we had three classes of preferred stock outstanding, all of which converted into common stock upon the IPO; Class A Preferred Stock, Class B Senior Convertible Preferred Stock (“Class B Preferred Stock”), and Junior Preferred Stock.

A summary of our preferred stock activity for the years ended December 31, 2013 and 2012, is as follows (in thousands):

Each class of preferred stock was measured at fair value upon issuance and recorded outside of permanent equity because the investors could redeem the shares in the future outside of our control. All three classes of preferred stock were being accreted to stated value over the period from the date of issuance to the earliest redemption date using the effective interest method. The initial stated capital of each of the three classes of preferred stock was $10,000 per share. All classes of preferred stock had voting rights proportionate to their ownership interest in us and had participation rights in any dividends issued on the common stock. The Class A Preferred Stock and Class B Preferred Stock earned a quarterly preferred return of 6%, which we elected to pay in-kind, while the Junior Preferred Stock did not pay a quarterly preferred return. All three classes of our preferred stock included antidilution adjustment provisions, although during the period when the preferred stock was outstanding, only the Conversion Price of the Junior Preferred Stock was impacted by such provisions.

The Class A Preferred Stock included a liquidation preference that provided for a minimum rate of investment return, which represented an embedded derivative and required bifurcation from the Class A Preferred Stock and separate accounting as a derivative liability. The liquidity feature, when classified as a derivative liability, was initially recorded at fair value and marked to fair value at the end of each reporting period. As noted above, upon consummation of the IPO, 2,135,602 shares of common stock were issued in connection with the liquidation preference associated with our Class A Preferred Stock resulting in a $36.3 million charge recorded in our consolidated statements of operations for the year ended December 31, 2013. Due to changes in the fair value of the derivative liability, $9.6 million of income was recorded to fair value derivative adjustments in our consolidated statements of operations for the year ended December 31, 2012.

See Note 9, “Fair Value of Financial Assets and Liabilities,” for additional discussion regarding the fair value derivative adjustments.

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 Amended and Restated Senior Term Facility and the Alaska Facility, both of which are reflected on the consolidated balance sheet at cost, as defined in Note 6, “Long-Term Debt and Other Liabilities”. Based on market conditions as of December 31, 2014, the fair value of the Amended and Restated Senior Term Facility was approximately $339 million with a carrying value of $309.2 million and the fair value of the Alaska Facility approximated its carrying value of $1.0 million (see Note 6, “Long-Term Debt and Other Liabilities”). These fair value measurements are classified as Level 2 within the fair value hierarchy since they are determined based upon significant inputs observable in the market including interest rates on recent financings by entities with credit profiles similar to ours. We estimated the fair values of the Amended Senior Term Facility and the Alaska Facility by calculating the upfront cash payment a market participant would require to assume these obligations. The upfront cash payment, excluding any issuance costs, is the amount that a market participant would be able to lend at December 31, 2014 to an entity with a credit rating similar to ours and achieve sufficient cash inflows to cover the scheduled cash outflows under the Amended and Restated Senior Term Facility and the Alaska Facility.

Derivative Liabilities:

As described in Note 8, “Common Stock and Preferred Stock” the liquidation preference associated with our pre-IPO Class A Senior Convertible Preferred Stock was considered an embedded derivative as it provided for a minimum return upon a Deemed Liquidation Event, such as an IPO. Upon consummation of the IPO, 2,135,602 common shares were issued in connection with the liquidation preference minimum return. As the public offering price of the shares sold in the offering was $17.00 per share, the value of the liquidation preference was $36.3 million, which we believe constitutes Level 2 observable inputs.

When outstanding the embedded derivatives in our pre-IPO preferred stock were marked to fair value at the end of each reporting period, resulting in a noncash charge/benefit to other (income) expense in our consolidated statements of operations. The fair value of the embedded derivatives was valued using an income approach and a probability-weighted expected return method (“PWERM”) using Level 3 unobservable inputs, as the income approach and PWERM were deemed to best represent the valuation models investors would likely use in valuing us.

There were no fair value measurements using Level 3 inputs related to our derivative liabilities for the years ended December 31, 2014 or 2013. The following table presents the fair value reconciliation of Level 3 derivative liabilities measured at fair value on a recurring basis for the year ended December 31, 2012 (in thousands):


	Class A Preferred Stock
Balance at January 1, 2012	$	9,640
Included in other (income) expense		(9,640	)

Balance at December 31, 2012	$	—

FCC Licenses:

In performing the annual impairment assessment of our FCC licenses, the fair value of the FCC license is determined using an income-based approach (the Greenfield method) using Level 3 unobservable inputs. Significant Level 3 inputs include projected future cash flows and the discount rate used to calculate the present value of the prospective cash flows.

Segment Reporting [Abstract]

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 international flights of North American based commercial airlines, is in the start-up phase as we launched commercial international connectivity service in March 2014. 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 will be provided. Additionally, CA-ROW generates revenue from monthly service fees charged to our airline partners for network monitoring and portal management services.

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, 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, 2014 and 2013. 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 compensation expense, write off of deferred equity financing costs, and, for periods prior to the IPO, Class A and Class B Senior Convertible Preferred Stock return and accretion of preferred stock). 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.

11. Share-Based Compensation

As of December 31, 2014, we maintained two share-based employee compensation plans: 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 “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 to eligible employees, directors and consultants, as determined by the Compensation Committee of our Board of Directors.

Under the Stock Plans, 11,956,570 shares of common stock were reserved for issuance. As of December 31, 2014, 3,785,863 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.

Our share-based compensation expense totaled $9.8 million, $5.6 million and $3.5 million for the years ended December 31, 2014, 2013, and 2012, respectively. The share-based compensation expense includes $7.2 million, $5.3 million and $3.5 million of expense that was valued using a BlackScholes option-pricing model, primarily relating to stock options.

A summary of stock option activity for the year ended December 31, 2014, is as follows:


	Number of Options			Weighted Average Exercise Price Per Share		Weighted Average Remaining Contractual Life		Aggregate Intrinsic Value
Options outstanding—January 1, 2014		5,165,819		$	13.89		7.20	$	56,517
Granted		1,772,374		$	17.67

Forfeited		(178,620	)	$	18.07

Options outstanding—December 31, 2014		6,415,540		$	14.98		7.40	$	16,501

Options exercisable—December 31, 2014		3,450,944		$	12.38		6.19	$	16,361

Options vested and expected to vest—December 31, 2014		6,273,253		$	14.91		7.36	$	16,498

There were no stock options exercised prior to 2013. As of December 31, 2014, total unrecognized compensation costs related to unvested stock options were approximately $20.6 million which is expected to be recognized over a weighted average period of 2.8 years. The total grant date fair value of stock options vested in 2014, 2013 and 2012 was approximately $6.0 million, $4.1 million and $3.2 million, respectively.

We estimate the fair value of stock options using the BlackScholes option-pricing model. Weighted average assumptions used and weighted average grant date fair value of stock options granted for the years ended December 31, 2014, 2013, and 2012, were as follows:


	2014			2013			2012
Approximate risk-free interest rate		1.9	%		1.3	%		1.0	%
Average expected life (years)		6.20			6.22			6.25
Dividend yield		N/A			N/A			N/A
Volatility		43.5	%		44.1	%		44.5	%
Weighted average grant date fair value of common stock underlying options granted	$	17.67		$	19.00		$	16.27
Weighted average grant date fair value of stock options granted	$	7.88		$	8.37		$	6.76

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. Given the short trading history as a public company, the expected volatility was based on calculated enterprise value volatilities for publicly traded companies in the same industry and general stage of development.

The following table summarizes the activities for our unvested RSUs and DSUs for the year ended December 31, 2014:


	Number of Underlying Shares			Weighted Average Grant Date Fair Value
Unvested—January 1, 2014		35,280		$	26.67
Granted		613,366		$	17.65
Vested		(39,850	)	$	18.01
Forfeited/canceled		(26,000	)	$	18.30

Unvested—December 31, 2014		582,796		$	18.14

Expected to vest after December 31, 2014		549,522

As of December 31, 2014, there was $12.4 million of unrecognized compensation cost related to unvested employee RSUs. This amount is expected to be recognized over a weighted-average period of 3.4 years. The total grant date fair value of RSUs and DSUs vested in 2014 was approximately $0.7 million. To the extent the actual forfeiture rate differs from what we have estimated, stock-based compensation related to these awards will be different from our expectations.

The following table summarizes the activity for our restricted stock for the year ended December 31, 2014:


	Number of Underlying Shares			Weighted Average Grant Date Fair Value
Unvested—January 1, 2014		—		$	—
Granted		182,461		$	17.69
Vested		—		$	—
Forfeited/canceled		(6,000	)	$	17.68

Unvested—December 31, 2014		176,461		$	17.69

Expected to vest after December 31, 2014		170,461

As of December 31, 2014, there was $2.8 million of unrecognized compensation cost related to unvested employee restricted stock. This amount is expected to be recognized over a weighted-average period of 3.4 years. To the extent the actual forfeiture rate differs from what we have estimated, stock-based compensation related to these awards will be different from our expectations.

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 28,084 shares of common stock were issued during the year ended December 31, 2014, the first year of issuance.

2007 Plan—ACM was a separate limited liability company established solely for the purpose of granting ownership interests to members of management. The ownership interests granted via ACM represented a net profits interests plan and are referred to as the 2007 Plan. Prior to the distribution discussed below, ACM owned approximately 821,411 shares of our common stock. Each outstanding ACM unit represented a proportionate interest in the 821,411 shares of common stock, or 0.048413 shares of common stock per ACM unit. The 2007 Plan was initiated on March 1, 2007, and the initial grants under the 2007 Plan were deemed to occur on that date for accounting purposes, although more than 90% of the ACM units were committed prior to March 1, 2007. The initial grants had vesting periods that began at various dates between July 1, 2006 and March 1, 2007, based on the grantees’ employment dates. In accordance with the tax regulations associated with net profits interests plans, a plan participant who receives an ACM Unit only participates in the equity value created after the issuance of the ACM Unit to the participant. Approximately 13.8 million ACM units were granted with a vesting period commencing on July 1, 2006, and participate in the full value of the ACM unit. No cash was paid by the employee to us upon vesting of the ACM unit.

ACM units generally vested over a four-year period, and upon termination of employment, any unvested ACM units held by the participant were forfeited and became available for future grants. At December 31, 2012, 396,640 ACM units were authorized and available for grant. On December 18, 2013, the remaining ACM units previously forfeited and available to be granted, were granted to existing ACM unit holders still employed by or serving as a director in amounts determined by the Compensation Committee. As a result of this grant we recognized stock compensation expense of $0.5 million in 2013.

On December 18, 2013, ACM distributed 821,346 shares of our common stock owned by ACM, with each of the members of ACM receiving a proportionate distribution of our common stock based on the number of vested units they held. An immaterial amount of shares, representing the individual members’ interests in fractional shares, were paid in cash at the time of distribution. Subsequently these shares were canceled. ACM was dissolved in 2014.

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 2014, 2013, and 2012, which means we are in a domestic three-year cumulative loss position. As a result of this and other assessments in fiscal 2014, 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, 2014, the federal net operating loss (“NOL”) carryforward amount was approximately $248 million and the state NOL carryforward amount was approximately $155 million. The federal NOLs begin to expire in 2031. The state NOLs expire in various tax years beginning 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, Canada, Switzerland, Japan and various states. With few exceptions, as of December 31, 2014, we are no longer subject to U.S. federal, state, local or foreign examinations by tax authorities for years before 2011.

As of December 31, 2014 and 2013, 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.

In 2013 and 2014, the IRS issued final regulations that provide guidance with respect to (i) the treatment of material and supplies, (ii) capitalization of amounts paid to acquire or produce tangible property, (iii) the determination of whether an expenditure with respect to tangible property is a deductible repair or a capital expenditure and (iv) dispositions of MACRS property. The adoption of these final regulations did not have a material impact on our results of operations, financial position, or cash flows.

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 the Gogo^® service to passengers on the aircraft. Depending on the agreement, we may be responsible for the costs of installing and 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 where legal title transfers are not deemed to be sales transactions 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 $12.8 million, $8.1 million and $3.7 million for the years ended December 31, 2014, 2013 and 2012, respectively, as a reduction to our cost of service revenue in our consolidated statements of operations. As of December 31, 2014, deferred airborne lease incentives of $13.8 million and $83.8 million are included in current and non-current liabilities, respectively, in our consolidated balance sheet. As of December 31, 2013, deferred airborne lease incentives of $9.0 million and $53.0 million are included in current and non-current liabilities, respectively, in our condensed consolidated balance sheet.

The revenue share paid to our airline partners represents an operating lease payment and is 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. As such, 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 $40.3 million, $33.3 million and $21.1 million for the years ended December 31, 2014, 2013 and 2012, respectively.

One contract with one of our airline partners requires us to provide our airline partner with a cash rebate of $1.8 million if our service is available on a specified number of aircraft in such airline partner’s fleet on the preceding December 31, in June of each year from 2015 through 2023. Based upon the number of aircraft in service on December 31, 2014, we will be required to rebate $1.8 million to this airline in June 2015.

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 $10.8 million, $5.7 million and $5.0 million for the years ended December 31, 2014, 2013, and 2012, respectively. 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 of up to five years with up to four five-year renewal options. Total cell site rental expense was $8.7 million, $7.6 million and $6.2 million for the years ended December 31, 2014, 2013, and 2012, respectively.

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 2014, are as follows (in thousands):


Years ending December 31,	Operating Leases

2018	$	14,781
2019	$	14,151
Thereafter	$	120,695

Equipment Leases—We lease certain computer and network equipment under capital leases, for which interest has been imputed with an annual interest rate of 5.9% to 13.4%. As of December 31, 2014 the computer equipment leases were classified as part of office equipment, furniture, fixtures and other in our consolidated balance sheet at a gross cost of $1.3 million. As of December 31, 2014 the network equipment leases were classified as part of network equipment in our consolidated balance sheet at a gross cost of $6.4 million. Annual future minimum obligations under capital leases for each of the next five years and thereafter, as of December 31, 2014, are as follows (in thousands):

Commitments and Contingencies	12 Months Ended
Commitments and Contingencies	Dec. 31, 2014
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	15. Commitments and Contingencies Contractual Commitments—We have agreements with airborne equipment vendors under which we have remaining commitments to purchase $14.2 million in satellite based systems and development services as of December 31, 2014. Such commitments will become payable as we receive the equipment and are provided the development services. We have agreements with vendors to provide us with transponder and teleport satellite services. These agreements vary in length and amount and commit us to purchase transponder and teleport satellite services totaling approximately $33.5 million in 2015, $33.3 million in 2016, $31.8 million in 2017, $15.2 million in 2018 and an amount less than $0.1 million in 2019. Damages and Penalties—Certain of our agreements with our airline partners may require us to incur additional obligations as a result of the occurrence of specified events, some of which may be out of our control. One contract covering the international fleet of one of our airline partners requires us to provide a credit or refund of up to $25 million to our airline partner if a competing airline installs satellite connectivity systems on a certain number of aircraft in its international fleet more quickly than we install our system on the same number of aircraft in our airline partner’s international fleet. The refund or credit will be eliminated in its entirety if we complete full installation of our airline partner’s international fleet by January 1, 2015, which date may be extended by up to six months as a result of certain excusable delays, and has been and will continue to be reduced proportionately from the maximum amount for every installation that we complete before the competitor achieves the target. The amount of any such refund or credit depends on a number of facts and circumstances, such as the pace at which we install satellite systems on aircraft delivered to us by our airline partner, as well as some that are not under our control, including, but not limited to, the number of installable aircraft made available to us from our airline partner’s international fleet, our competitor’s ability to install an equal or greater quantity of satellite systems on such competing airline’s international fleet and any current or future regulatory delays to the extent they are not excusable delays. Any refund or credit may only be applied toward the purchase of equipment or for a refund of amounts paid by the airline for previously purchased equipment. One contract with another of our airline partners obligates us to pay our airline partner up to $6 million in penalties and installation and other costs if we fail to receive certain regulatory approvals or fail to begin the installation of equipment related to the provision of satellite-based service by specified deadlines. 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 unable to install our equipment on aircraft by specified timelines. 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, including the number of aircraft that are not installed on schedule, the length of time by which the installation is delayed, and the unit of time by which the delay is measured. 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. Berkson Litigation—On February 25, 2014, Adam Berkson filed suit against us in the United States District Court for the Eastern District of New York, on behalf of putative classes of national purchasers and a subclass of New York purchasers of our connectivity service, alleging claims that we violated New York and other consumer protection laws, as well as an implied covenant of good faith and fair dealing, by misleading consumers about recurring charges for our service. The suit seeks unspecified damages. We have not accrued any liability related to this matter because, due to the early stage of the litigation, the strength of our defenses and a range of possible loss, if any, cannot be determined. Based on currently available information, we believe we have strong defenses and intend to defend this lawsuit vigorously, but the outcome of this matter is inherently uncertain and may have a material adverse effect on our financial position, results of operations and cash flows. Airfone Acquisition—As disclosed in Note 17 “Airfone Acquisition”, in connection with the Airfone Acquisition, we determined that Airfone failed to remit to the Universal Services Administration Company (“USAC”) certain FCC-mandated Federal Universal Service Fund (“FUSF”) fees. We therefore have caused Airfone to correct its past filings and to remit to USAC approximately $1.4 million in FUSF and related fees covering the period from January 1, 2008 through April 10, 2013. We also determined that Airfone billed its customers for FUSF fees in amounts that exceed the total amount remitted or owed to USAC. Due to the difference between the total amounts collected and the amounts that have been or will be remitted to USAC, Airfone also owed refunds to its customers. In June 2014 we refunded to Airfone’s customers amounts which we believe satisfy our obligations. In addition, Airfone may be subject to enforcement action by the FCC in connection with the delayed payments to USAC, which could result in, among other things, interest payments, penalties and fines. LiveTV has reimbursed us for the amounts paid to USAC and customers to date, and has agreed to indemnify us for any additional amounts due to Airfone’s customers or USAC as well as any interest, penalties and fines for which Airfone may be liable.

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, 2014 and 2013 the one-time payment had balances of $0.1 million and $0.1 million included in prepaid expenses and other current assets, respectively, and $2.4 million and $2.7 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
2015	$	112
2016	$	112
2017	$	112
2018	$	112
2019	$	112
Thereafter	$	1,970

Amortization expense totaled $0.1 million for both of the years ended December 31, 2014 and 2013.

The monthly payments are expensed as incurred and totaled approximately $1.1 million and $1.0 million for the years ended December 31, 2014 and 2013, respectively.

Airfone Acquisition

17. Airfone Acquisition

On April 11, 2013, we consummated the acquisition from LiveTV, LLC (“LiveTV”) of LiveTV Airfone, LLC (“Airfone”) which had more than 1,000 subscribers for its airborne voice communication services and a Federal Communications Commission (“FCC”) license for 1 MHz of ATG spectrum in the nationwide 800MHz Commercial Air-Ground Radiotelephone band (“1 MHz FCC License”). The purchase price for the acquisition was $9.3 million. In connection with the acquisition, we also agreed to license certain intellectual property rights from LiveTV. The purchase price was funded from cash on-hand and of the $9.3 million purchase price, $1.0 million remained in escrow and is included in restricted cash along with a corresponding amount in accrued liabilities on our consolidated balance sheet as of December 31, 2013. This acquisition did not have a material impact on our financial statements. Accordingly, we have not presented pro forma disclosures.

The Airfone acquisition is accounted for under the acquisition method of accounting and the results of operations are included in our financial statements from the date of acquisition. The allocation of the purchase price is a follows (in thousands):


	Purchase Price Allocation
Trade receivables	$	422
Prepaid and other current assets		3,768
Property and equipment		2,232
Trademark/trade name		220
