Basis of Presentation

1.	Basis of Presentation

The Business - Gogo Inc. (“we”, “us”, “our”) is a holding company, which through its operating subsidiaries is a provider of in-flight connectivity and wireless in-cabin digital entertainment solutions. We operate through the following three segments: Commercial Aviation North America or “CA-NA”, Commercial Aviation Rest of World or “CA-ROW” and Business Aviation or “BA”. Services provided by our CA-NA and CA-ROW businesses include Gogo Connectivity, which allows passengers to connect to the internet from their personal Wi-Fi-enabled devices; Gogo Vision, which offers passengers the opportunity to enjoy a broad selection of in-flight entertainment options on their personal Wi-Fi enabled devices; and other service revenue, which include a broad range of customizable, targeted content, advertising and e-commerce services. Services are provided by the CA-NA business on commercial aircraft flying routes that generally begin and end within North America, which for this purpose includes the United States, Canada and Mexico. Our CA-ROW business, which is in the start-up phase as we launched commercial international service in March 2014, provides service on commercial aircraft operated by foreign-based commercial airlines and international flights of 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. Our BA business provides in-flight internet connectivity and other voice and data communications products and services and sells equipment for in-flight telecommunications to the business aviation market. BA services include Gogo Biz, our in-flight broadband service which utilizes our ATG network and spectrum, Gogo Vision, and satellite-based voice and data services through our strategic alliances with satellite companies.

Basis of Presentation - The accompanying unaudited condensed consolidated financial statements and notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in conformity with Article 10 of Regulation S-X promulgated under the Securities Act of 1933, as amended. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements and should be read in conjunction with our annual audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2014 as filed with the Securities Exchange Commission (“SEC”) on February 27, 2015 (the “2014 10-K”). These unaudited condensed consolidated financial statements reflect, in the opinion of management, all material adjustments (which include normal recurring adjustments) necessary to fairly state, in all material respects, our financial position, results of operations and cash flows for the periods presented.

The results of operations and cash flows for the three and nine month periods ended September 30, 2015 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2015.

We have one class of common stock outstanding as of September 30, 2015 and December 31, 2014.

Use of Estimates - The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis, management evaluates the significant estimates and bases such estimates on historical experience and on various other assumptions believed to be reasonable under the circumstances. However, actual results could differ materially from those estimates.

Reclassifications - In order to conform to the current year presentation, certain amounts in our 2014 unaudited condensed consolidated statements of cash flows have been reclassified. Specifically, accrued interest is stated separately in the unaudited condensed consolidated statement of cash flows. For the nine month period ended September 30, 2014, accrued interest of $9 thousand had been included in accrued liabilities in our unaudited condensed consolidated statement of cash flows.

Accounting Changes and Error Corrections [Abstract]

Recent Accounting Pronouncements

2.	Recent 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. 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. This standard will be applied using either the full or modified retrospective adoption methods. We will adopt this guidance as of January 1, 2018. 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 requires that management 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.

In April 2015, the FASB issued ASU 2015-03, Interest – Imputation of Interest (Subtopic 835-30) (“ASU 2015-03”), which requires that debt issuance costs be presented in the balance sheets as a direct deduction from the carrying amount of the related debt liability. The new requirement is effective for fiscal years beginning on or after December 15, 2015, and for interim periods within those fiscal years. Retrospective presentation is required for all comparable periods presented. As of September 30, 2015, we have $17.7 million of debt issuance costs that will be reclassified from a long-term asset to a reduction in the carrying amount of our debt when this requirement becomes effective.

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory (“ASU 2015 -11”), which requires entities to measure most inventory “at the lower of cost and net realizable value,” thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market (market in this context is defined as one of three different measures). ASU 2015-11 will not apply to inventories that are measured by using either the last-in, first-out (LIFO) method or the retail inventory method (RIM). ASU 2015-11 is effective prospectively for annual periods beginning after December 15, 2016, and interim periods therein. We are currently evaluating the impact of the adoption of this guidance on our financial position, results of operations and cash flows.

- Definition

The entire disclosure of changes in accounting principles, including adoption of new accounting pronouncements, that describes the new methods, amount and effects on financial statement line items.

Net Loss Per Share

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 8, “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 September 30, 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 the three and nine month periods ended September 30, 2015 and 2014, all of the outstanding shares of common stock underlying stock options, 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 three and nine month periods ended September 30, 2015 and 2014; however, because of the undistributed losses, the shares of common stock associated with the Forward Transactions are excluded from the computation of basic earnings per share in 2015 as undistributed losses are not allocated to these shares (in thousands, except per share amounts):

Inventory Disclosure [Abstract]

Inventories

4.	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.

Inventories as of September 30, 2015 and December 31, 2014, all of which were included within the BA segment, were as follows (in thousands):


	September 30, 2015		December 31, 2014
Work-in-process component parts	$	13,427	$	16,578
Finished goods		8,484		5,335

Total inventory	$	21,911	$	21,913

- Definition

The entire disclosure for inventory. This may include, but is not limited to, the basis of stating inventory, the method of determining inventory cost, the major classes of inventory, and the nature of the cost elements included in inventory. If inventory is stated above cost, accrued net losses on firm purchase commitments for inventory and losses resulting from valuing inventory at the lower-of-cost-or-market may also be included. For LIFO inventory, may disclose the amount and basis for determining the excess of replacement or current cost over stated LIFO value and the effects of a LIFO quantities liquidation that impacts net income.

Goodwill and Intangible Assets Disclosure [Abstract]

Intangible Assets

6.	Intangible Assets

Our intangible assets are comprised of both indefinite-lived and finite-lived intangible assets. Intangible assets with indefinite lives and goodwill 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 our indefinite-lived intangible assets and goodwill during the fourth quarter of each fiscal year. We also reevaluate the useful life of the indefinite-lived intangible assets each reporting period to determine whether events and circumstances continue to support an indefinite useful life. The results of our annual indefinite-lived intangible assets and goodwill impairment assessments in the fourth quarter of 2014 indicated no impairment.

As of September 30, 2015 and December 31, 2014, our goodwill balance, all of which related to our BA segment, was $0.6 million.

Our intangible assets, other than goodwill, as of September 30, 2015 and December 31, 2014 were as follows (in thousands, except for weighted average remaining useful life):

Amortization expense was $4.9 million and $13.1 million for the three and nine month periods ended September 30, 2015, respectively, and $2.5 million and $8.0 million, respectively, for the comparable prior year periods.

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

Our BA segment provides warranties on parts and labor for our systems. 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 unaudited condensed consolidated balance sheet. Our warranty reserve balance was $1.5 million and $1.1 million as of September 30, 2015 and December 31, 2014, respectively.

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 of 1933, as amended. 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. We expect to use the net proceeds from the Convertible Notes, after giving effect of the Forward Transactions (as defined below), for working capital and other general corporate purposes, including potential costs associated with developing and launching our next-generation technology solutions and the acquisition of additional spectrum should it become available. 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, beginning on September 1, 2015.

The $361.9 million of proceeds received from the issuance of the Convertible Notes were 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 unaudited condensed 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 unaudited condensed consolidated statements of operations through the Convertible Notes maturity date (see Note 9, “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% for the nine month period ended September 30, 2015. The equity component will not be remeasured as long as it continues to meet the conditions for equity classification.

As of September 30, 2015, the outstanding principal on the Convertible Notes was $361.9 million, the unamortized debt discount was $91.5 million, and the net carrying amount of the liability component was $270.4 million, which was recorded as long-term debt within the unaudited condensed consolidated balance sheet.

We incurred approximately $10.4 million of issuance costs related to the issuance of the Convertible Notes. Of the $10.4 million of issuance costs incurred, $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 unaudited condensed consolidated balance sheet is being amortized over the contractual term of the Convertible Notes using the effective interest method. Total amortization expense of the deferred financing costs was $0.3 million and $0.7 million for the three and nine month periods ended September 30, 2015, respectively. As of September 30, 2015, the balance of unamortized deferred financing costs related to the Convertible Notes was $6.8 million. See Note 9, “Interest Costs” for additional information.

The Convertible Notes had an initial conversion rate of 41.9274 common shares per $1,000 principal amount of the 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 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 nine month period ended September 30, 2015. Regardless of whether any of the foregoing circumstances occurs, holders may convert their 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 their 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 unaudited condensed 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.

Senior Term Facility – 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 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”). As of September 30, 2015 and December 31, 2014, we had $303.2 million and $309.2 million, respectively, outstanding under the Amended and Restated Senior Term Facility.

The maturity date of the Amended and Restated Senior Term Facility is 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.

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 September 30, 2015, 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 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 $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 have been accounted for as deferred financing costs. The $4.1 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 amendments in April 2013 and July 2014 and were expensed to interest expense. Total amortization expense of the deferred financing costs was $0.8 million and $2.3 million for the three and nine month periods ended September 30, 2015, respectively, and $0.8 million and $2.5 million, respectively, for the comparable prior year periods. Amortization expense is included in interest expense in the unaudited condensed consolidated statements of operations. As of September 30, 2015 and December 31, 2014, the balance of unamortized deferred financing costs related to the Amended and Restated Senior Term Facility was $9.0 million and $11.3 million, respectively.

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 (period from October 1 to December 31)	$	1,733
2016	$	6,932
2017	$	6,932
2018	$	287,639
Thereafter	$	—

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. In the event actual results or a change in estimates triggers the mandatory prepayment, such prepayment amount will be reclassified from non-current liabilities to current liabilities in our unaudited condensed consolidated balance sheet. Though we anticipate that we will have a mandatory prepayment due in 2016 based on 2015 results, the amount is not determinable and therefore no mandatory prepayment is classified as a current liability as of September 30, 2015.

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. 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.

Letters of Credit - We maintain several letters of credit totaling $7.9 million as of both September 30, 2015 and December 31, 2014. 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, Illinois; Bensenville, Illinois; and Broomfield, Colorado and our former office location in Itasca, Illinois.

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 unaudited condensed consolidated balance sheets, as noted in Note 5, “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 unaudited condensed 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 $5.1 million and $13.7 million for the three and nine month periods ended September 30, 2015, respectively, and $3.5 million and $9.2 million for the comparable prior year periods, respectively, as a reduction to our cost of service revenue in our unaudited condensed consolidated statements of operations. As of September 30, 2015, deferred airborne lease incentives of $19.1 million and $107.6 million are included in current and non-current liabilities, respectively, in our unaudited condensed consolidated balance sheet. 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 unaudited 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. 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 $9.9 million and $30.8 million for the three and nine month periods ended September 30, 2015, respectively, and $9.5 million and $29.2 million, respectively, for the comparable prior year periods.

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.

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 $3.4 million and $11.1 million for the three and nine month periods ended September 30, 2015, respectively, and $2.1 million and $6.1 million, respectively, for the comparable prior year periods. 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 $2.2 million and $6.8 million for the three and nine month periods ended September 30, 2015, respectively, and $2.2 million and $6.5 million, respectively, for the comparable prior year periods.

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 September 30, 2015, are as follows (in thousands):

Equipment Leases – We lease certain computer and network equipment under capital leases, for which interest has been imputed with annual interest rates ranging from 8.3% to 11.7%. As of September 30, 2015, the computer equipment leases were classified as part of office equipment, furniture, and fixtures and other in our unaudited condensed consolidated balance sheet at a gross cost of $3.5 million. As of September 30, 2015 the network equipment leases were classified as part of network equipment in our unaudited condensed consolidated balance sheet at a gross cost of $7.5 million.

Commitments and Contingencies

Contractual Commitments - We have agreements with airborne equipment vendors under which we have remaining commitments to purchase $12.4 million in satellite based systems and development services as of September 30, 2015. Such commitments will become payable as we receive the equipment or 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 $9.1 million in 2015 (October through December), $34.4 million in 2016, $32.7 million in 2017, $15.7 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 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 has been and will continue to be reduced proportionately from the maximum amount for every installation that we complete before our competitor achieves the target, after taking into account excusable delays. As of September 30, 2015, the maximum amount of the potential credit or refund was approximately $6 million. The actual amount of any such refund or credit depends on a number of facts and circumstances, such as the pace at which we continue to 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. Based on actual and forecasted installations as of September 30, 2015, we currently expect to meet the installation schedule before our competitor does, after taking excusable delays into account, and, therefore, we do not believe it is reasonably possible that we will incur a material loss. We continuously monitor the status of installations under this contract and will accrue the applicable refund or credit amount should it become probable that our competitor will complete the targeted number of installations before we do, after taking into account excusable delays.

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 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.

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 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. In May 2014, we filed motions to compel arbitration and dismiss the suit, moving in the alternative to transfer venue and/or dismiss for lack of standing. In April 2015, the court denied our motions in their entirety, and in May 2015, we filed notice of appeal to the United States Court of Appeals for the Second Circuit. In October 2015, we and representatives of the putative classes entered into a settlement agreement under which eligible class members would be entitled to receive agreed-upon amounts of complementary Gogo connectivity service and we would be responsible for claims administration costs and plaintiffs’ legal fees. The estimated cost of the contemplated settlement is not material. The settlement is subject to court approval which has not yet been obtained. In the event that the court does not approve the settlement as currently proposed and agreement on alternative terms acceptable to both parties and the court cannot be reached, we intend to proceed with our appeal.

Fair Value of Financial Assets and Liabilities

Fair Value Disclosures [Abstract]

Fair Value of Financial Assets and Liabilities

12.

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 Convertible Notes and the Amended and Restated Senior Term Facility (each as defined in Note 8, “Long-Term Debt and Other Liabilities”), both of which are reflected on the unaudited condensed consolidated balance sheet at cost. The fair value of the Convertible Notes was approximately $320 million, with a carrying value of $270.4 million as of September 30, 2015 (the carrying value does not include the conversion premium). The fair value of the Amended and Restated Senior Term Facility was approximately $328 million and $339 million as of September 30, 2015 and December 31, 2014, respectively, with a carrying value of $303.2 million and $309.2 million as of September 30, 2015 and December 31, 2014, respectively. These fair value measurements are classified as Level 2 within the fair value hierarchy since they are based on quoted market prices of identical instruments in markets that are not active. We estimated the fair value of the Convertible Notes and Amended and Restated Senior Term 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 September 30, 2015 to an entity with a credit rating similar to ours and achieve sufficient cash inflows to cover the scheduled cash outflows under the Convertible Notes and Amended and Restated Senior Term Facility.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Income Tax

The effective income tax rates for the three and nine month periods ended September 30, 2015 were (0.9%) and (1.3%), respectively, and (1.2%) and (1.6%), respectively, for the comparable prior year periods. Income tax expense recorded in each period was similar, with differences in pre-tax income causing the change in the effective tax rate. The difference between our effective tax rates and the U.S. federal statutory rate of 35% for the three and nine month periods ended September 30, 2015 and 2014 was primarily due to the recording of a valuation allowance against our net deferred tax assets which is excluded from taxable income (loss).

We are subject to taxation in the United States, Canada, Switzerland, Japan, Singapore, Mexico, Brazil and various states. With few exceptions, as of September 30, 2015, we are no longer subject to U.S. federal, state, foreign or local examinations by tax authorities for years prior to 2011.

We record penalties and interest relating to uncertain tax positions in the income tax provision line item in the unaudited condensed consolidated statement of operations. No penalties or interest related to uncertain tax positions were recorded for the three and nine month periods ended September 30, 2015. As of September 30, 2015, we did not have a liability recorded for interest or potential penalties.

We do not expect 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.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Segment Reporting [Abstract]

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”. See Note 1, “Basis of Presentation” for further information regarding our segments.

The accounting policies of the operating segments are the same as those described in Note 2, “Summary of Significant Accounting Policies” in our 2014 10-K. 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 these assets are not material as of September 30, 2015 and December 31, 2014. 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, certain non-cash charges (including amortization of deferred airborne lease incentives and stock-based compensation expense) and other income (expense). 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 — We have two stock-based employee compensation plans as of September 30, 2015. See Note 11, “Share-Based Compensation,” in our 2014 10-K for further information regarding these plans. For the nine month period ended September 30, 2015, options to purchase 1,422,606 shares of common stock were granted, options to purchase 172,891 shares of common stock were forfeited, options to purchase 13,727 shares of common stock expired, and options to purchase 384,381 shares of common stock were exercised.

For the nine month period ended September 30, 2015, 605,605 restricted share units (“RSUs”) were granted, 118,625 RSUs vested and 78,782 RSUs were forfeited.

For the nine month period ended September 30, 2015, 29,100 deferred share units (“DSUs”) were granted.

For the nine month period ended September 30, 2015, 84,990 shares of restricted stock were granted, 42,866 shares of restricted stock vested and 5,000 shares of restricted stock were forfeited. These shares are deemed issued as of the date of grant, but not outstanding until they vest.

The employee stock purchase plan (the “ESPP”) allows eligible employees to purchase our common stock through payroll deductions at a price equal to 90% of the lower of the fair market value of the stock as of the beginning or the end of three-month offering periods. Under the ESPP, 424,594 shares were reserved for issuance. The nine month period ended September 30, 2015 reflects the issuance of 51,212 shares of common stock under the ESPP. The first offering period under the ESPP commenced in the third quarter of 2014.

Stock-based compensation expense totaled $4.5 million and $10.8 million for the three and nine month periods ended September 30, 2015, respectively, and $2.9 million and $6.7 million, respectively, for the comparable prior year periods.

401(k) Plan — Under our 401(k) plan, all employees who are eligible to participate are entitled to make tax-deferred contributions, subject to Internal Revenue Service limitations. We match 100% of the employee’s first 4% of contributions made, subject to annual limitations. Our matching contributions were $0.9 million and $2.6 million for the three and nine month periods ended September 30, 2015, respectively, and $0.6 million and $1.8 million, respectively, for the comparable prior year periods.

Canadian ATG Spectrum License

Canadian ATG Spectrum License

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 US $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 US $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 unaudited condensed consolidated balance sheet at the time of payment. As of September 30, 2015, the one-time payment had balances of $0.1 million included in prepaid expenses and other current assets and $2.0 million included in other non-current assets, respectively, in our unaudited condensed 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 (period from October 1 to December 31)	$	25
2016	$	97
2017	$	97
2018	$	97
2019	$	97
Thereafter	$	1,707

Amortization expense totaled less than $0.1 million and $0.1 million during the three and nine month periods ended September 30, 2015 and 2014, respectively.

The monthly payments are expensed as incurred and totaled approximately $0.3 million and $0.8 million during the three and nine month periods ended September 30, 2015, respectively, and $0.3 million and $0.8 million, respectively, for the comparable prior year periods.

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. Our BA business provides in-flight internet connectivity and other voice and data communications products and services and sells equipment for in-flight telecommunications to the business aviation market. BA services include Gogo Biz, our in-flight broadband service which utilizes our ATG network and spectrum, Gogo Vision, and satellite-based voice and data services through our strategic alliances with satellite companies. *Basis of Presentation* - The accompanying unaudited condensed consolidated financial statements and notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in conformity with Article 10 of Regulation S-X promulgated under the Securities Act of 1933, as amended. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements and should be read in conjunction with our annual audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2014 as filed with the Securities Exchange Commission (“SEC”) on February 27, 2015 (the “2014 10-K”). These unaudited condensed consolidated financial statements reflect, in the opinion of management, all material adjustments (which include normal recurring adjustments) necessary to fairly state, in all material respects, our financial position, results of operations and cash flows for the periods presented. The results of operations and cash flows for the three and nine month periods ended September 30, 2015 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2015. We have one class of common stock outstanding as of September 30, 2015 and December 31, 2014.
Use of Estimates	*Use of Estimates* - The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis, management evaluates the significant estimates and bases such estimates on historical experience and on various other assumptions believed to be reasonable under the circumstances. However, actual results could differ materially from those estimates.
Reclassifications	Reclassifications - In order to conform to the current year presentation, certain amounts in our 2014 unaudited condensed consolidated statements of cash flows have been reclassified. Specifically, accrued interest is stated separately in the unaudited condensed consolidated statement of cash flows. For the nine month period ended September 30, 2014, accrued interest of $9 thousand had been included in accrued liabilities in our unaudited condensed consolidated statement of cash flows.
