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. Accordingly, the calculation of weighted average shares outstanding as of March 31, 2016 and 2015 excludes approximately 7.2 million shares that will be repurchased as a result of the Forward Transactions. As a result of the net loss for the three month periods ended March 31, 2016 and 2015, 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 month periods ended March 31, 2016 and 2015; 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 2016 and 2015 as undistributed losses are not allocated to these shares ( in thousands, except per share amounts For the Three Months Ended March 31, 2016 2015 Net loss $ (24,106 ) $ (20,092 ) Less: Participation rights of the Forward Transactions — — Undistributed losses $ (24,106 ) $ (20,092 ) Weighted-average common shares outstanding-basic and diluted 78,738 83,126 Net loss attributable to common stock per share-basic and diluted $ (0.31 ) $ (0.24 )

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 2015 indicated no impairment. As of March 31, 2016 and December 31, 2015, our goodwill balance, all of which related to our BA segment, was $0.6 million. Our intangible assets, other than goodwill, as of March 31, 2016 and December 31, 2015 were as follows ( in thousands, except for weighted average remaining useful life Weighted Average As of March 31, 2016 As of December 31, 2015 Remaining Gross Net Gross Net Useful Life Carrying Accumulated Carrying Carrying Accumulated Carrying (in years) Amount Amortization Amount Amount Amortization Amount Amortized intangible assets: Software 2.4 $ 97,454 $ (54,881 ) $ 42,573 $ 90,925 $ (50,760 ) $ 40,165 OEM and dealer relationships 0.8 6,724 (6,163 ) 561 6,724 (5,995 ) 729 Service customer relationship 4.1 8,081 (4,011 ) 4,070 8,081 (3,757 ) 4,324 Other intangible assets 3.9 1,500 (200 ) 1,300 1,500 (178 ) 1,322 Total amortized intangible assets 113,759 (65,255 ) 48,504 107,230 (60,690 ) 46,540 Unamortized intangible assets: FCC Licenses 32,283 — 32,283 32,283 — 32,283 Total intangible assets $ 146,042 $ (65,255 ) $ 80,787 $ 139,513 $ (60,690 ) $ 78,823 Amortization expense was $4.6 million and $3.5 million for the three month periods ended March 31, 2016 and 2015, respectively.

Warranties	7. Warranties We provide warranties on parts and labor related to our products. Our warranty terms range from two to five years. Warranty reserves are established for costs that are estimated to be incurred after the sale, delivery and installation of the products under warranty. The warranty reserves are determined based on known product failures, historical experience and other available evidence, and are included in accrued liabilities in our unaudited condensed consolidated balance sheets. Our warranty reserve balance was $2.0 million and $1.8 million as of March 31, 2016 and December 31, 2015, respectively.

Debt Disclosure [Abstract]
Long-Term Debt and Other Liabilities	8. Long-Term Debt and Other Liabilities Long-term debt as of March 31, 2016 and December 31, 2015 was as follows ( in thousands March 31, December 31, 2016 2015 Amended and Restated Senior Term Facility $ 287,657 $ 301,503 Convertible Notes 278,724 274,528 Total debt 566,381 576,031 Less current portion of long-term debt (6,652 ) (18,835 ) Less deferred financing costs (13,455 ) (14,623 ) Total long-term debt $ 546,274 $ 542,573 Convertible Notes The $361.9 million of proceeds received from the issuance of the Convertible Notes was initially allocated between long-term debt (the liability component) at $261.9 million, and additional paid-in-capital, (the equity component) at $100.0 million, within the 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%. The equity component will not be remeasured as long as it continues to meet the conditions for equity classification. As of March 31, 2016 and December 31, 2015, the outstanding principal on the Convertible Notes was $361.9 million for both periods, the unamortized debt discount was $83.2 million and $87.4 million, respectively, and the net carrying amount of the liability component was $278.7 million and $274.5 million, respectively. We incurred approximately $10.4 million of issuance costs related to the issuance of the Convertible Notes, of which $7.5 million and $2.9 million were recorded to deferred financing costs and additional paid-in capital, respectively, in proportion to the allocation of the proceeds of the Convertible Notes. The $7.5 million recorded as deferred financing costs on our unaudited condensed consolidated balance sheet is being amortized over the term of the Convertible Notes using the effective interest method. Total amortization expense of the deferred financing costs was $0.3 million and an amount of less than $0.1 million for the three month periods ended March 31, 2016 and 2015, respectively. Amortization expense is included in interest expense in the unaudited condensed consolidated statements of operations. As of March 31, 2016 and December 31, 2015, the balance of unamortized deferred financing costs related to the Convertible Notes was $6.1 million and $6.5 million, respectively, and is included as a reduction to long-term debt in our unaudited condensed consolidated balance sheets. 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 Convertible Notes, which is equivalent to an initial conversion price of approximately $23.85 per share of our common stock. Upon conversion, we currently expect to deliver cash up to the principal amount of the Convertible Notes then outstanding. With respect to any conversion value in excess of the principal amount, we currently expect to deliver shares of our common stock. We may elect to deliver cash in lieu of all or a portion of such shares. The shares of common stock subject to conversion are excluded from diluted earnings per share calculations under the if-converted method as their impact is anti-dilutive. Holders may convert the Convertible Notes, at their option, in multiples of $1,000 principal amount at any time prior to December 1, 2019, but only in the following circumstances: • during any fiscal quarter beginning after the fiscal quarter ended June 30, 2015, if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during the last 30 consecutive trading days of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price of the Convertible Notes on each applicable trading day; • during the five business day period following any five consecutive trading day period in which the trading price for the Convertible Notes is less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the Convertible Notes on each such trading day; or • upon the occurrence of specified corporate events. None of the above events allowing for conversion prior to December 1, 2019 occurred during the three month periods ended March 31, 2016 or 2015. Regardless of whether any of the foregoing circumstances occurs, a holder may convert its Convertible Notes, in multiples of $1,000 principal amount, at any time on or after December 1, 2019 until maturity. In addition, if we undergo a fundamental change (as defined in the indenture governing the Convertible Notes), holders may, subject to certain conditions, require us to repurchase their Convertible Notes for cash at a price equal to 100% of the principal amount of the Convertible Notes to be purchased, plus any accrued and unpaid interest. In addition, if specific corporate events occur prior to the maturity date, we will increase the conversion rate for a holder who elects to convert its Convertible Notes in connection with such a corporate event in certain circumstances. In connection with the issuance of the Convertible Notes, we paid approximately $140 million to enter into prepaid forward stock repurchase transactions (the “Forward Transactions”) with certain financial institutions (the “Forward Counterparties”), pursuant to which we purchased approximately 7.2 million shares of common stock for settlement on or around the March 1, 2020 maturity date for the Convertible Notes, subject to the ability of each Forward Counterparty to elect to settle all or a portion of its Forward Transactions early. As a result of the Forward Transactions, total shareholders’ equity within our 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. 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 March 31, 2016 and December 31, 2015, we had $287.7 million and $301.5 million, respectively, outstanding 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 must maintain a minimum cash balance of $5.0 million and comply with certain reporting and notice requirements and periodic financial statement reporting requirements on a borrowing entity basis. As of March 31, 2016, 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. 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 March 31, 2016, 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 $0.7 million for the three month periods ended March 31, 2016 and 2015, respectively. Amortization expense is included in interest expense in the unaudited condensed consolidated statements of operations. As of March 31, 2016 and December 31, 2015, the balance of unamortized deferred financing costs related to the Amended and Restated Senior Term Facility was $7.3 million and $8.2 million, respectively, and is included as a reduction to long-term debt in our unaudited condensed consolidated balance sheets.

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 We may voluntarily prepay the loans subject to conditions, prices and premiums as follows: (i) 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; (ii) On and after December 21, 2016, we may prepay loans at par.

Leases [Abstract]
Leases	10. Leases Arrangements with Commercial Airlines ® For the airline agreements where the equipment transactions are treated as operating leases of space, the revenue share paid to our airline partners represents operating lease payments. They are deemed to be contingent rental payments, as the payments due to each airline are based on a percentage of our CA-NA and CA-ROW service revenue generated from that airline’s passengers, which is unknown until realized. Therefore, we cannot estimate the lease payments due to an airline at the commencement of our contract with such airline. This rental expense is included in cost of service revenue and is offset by the amortization of the deferred airborne lease incentives discussed above. Such rental expenses totaled a net charge of $11.4 million and $10.3 million for the three month periods ended March 31, 2016 and 2015, respectively. One contract with one of our airline partners requires us to provide that 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, 2015, we will be required to rebate $1.8 million to this airline partner in June 2016. Leases and Cell Site Contracts 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 March 31, 2016 are as follows ( in thousands Operating Years ending December 31, Leases 2016 (period from April 1 to December 31) $ 14,462 2017 $ 17,829 2018 $ 15,176 2019 $ 14,532 2020 $ 13,487 Thereafter $ 108,146 Equipment Leases in thousands Capital Years ending December 31, Leases 2016 (period from April 1 to December 31) $ 2,191 2017 2,298 2018 726 Thereafter — Total minimum lease payments 5,215 Less: Amount representing interest (493 ) Present value of net minimum lease payments $ 4,722 The $4.7 million present value of net minimum lease payments as of March 31, 2016 has a current portion of $2.4 million included in the current portion of long-term debt and capital leases and a non-current portion of $2.3 million included in other non-current liabilities.

Commitments and Contingencies	11. Commitments and Contingencies Contractual Commitments We have agreements with vendors to provide us with transponder and teleport satellite services. These agreements vary in length and amount and as of March 31, 2016 commit us to purchase transponder and teleport satellite services totaling approximately $29.5 million in 2016 (April 1 through December 31), $41.9 million in 2017, $40.4 million in 2018, $45.3 million in 2019, $58.6 million in 2020 and $309.2 million thereafter. Damages and Penalties - Indemnifications and Guarantees 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.

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 • Level 2 • Level 3 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, both of which are reflected on the unaudited condensed consolidated balance sheet at cost. The fair value of the Convertible Notes was approximately $280 million and $352 million as of March 31, 2016 and December 31, 2015, respectively, with a carrying value of $278.7 million and $274.5 million as of March 31, 2016 and December 31, 2015, respectively (the carrying value does not include the conversion premium). The fair value of the Amended and Restated Senior Term Facility was approximately $286 million and $299 million as of March 31, 2016 and December 31, 2015, respectively, with a carrying value of $287.7 million and $301.5 million as of March 31, 2016 and December 31, 2015, respectively. These fair value measurements are classified as Level 2 within the fair value hierarchy since they are based on quoted market prices of our instruments in markets that are not active. We estimated the fair value of the 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 March 31, 2016 to an entity with a credit rating similar to ours and achieve sufficient cash inflows to cover the scheduled cash outflows under the Convertible Notes and Amended and Restated Senior Term Facility. The calculated fair value of our Convertible Notes is highly correlated to our stock price and as a result significant changes to our stock price could have a significant impact on the calculated fair value of our Convertible Notes.

Income Tax Disclosure [Abstract]
Income Tax	13. Income Tax The effective income tax rates for the three month periods ended March 31, 2016 and 2015 were (1.3%) and (1.5%), respectively. 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 month periods ended March 31, 2016 and 2015 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 income taxation in the United States, various states, Canada, Switzerland, Japan, Mexico, Brazil and Singapore. With few exceptions, as of March 31, 2016, we are no longer subject to U.S. federal, state, local or foreign examinations by tax authorities for years before 2012. 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 month periods ended March 31, 2016 and 2015. As of March 31, 2016 and December 31, 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.

Segment Reporting [Abstract]
Business Segments and Major Customers	14. 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 2015 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 March 31, 2016 and December 31, 2015. For our airborne assets, we consider only those assets installed in aircraft associated with international commercial airline partners to be owned outside of the United States. Management evaluates performance and allocates resources to each segment based on segment profit (loss), which is calculated internally as net income (loss) attributable to common stock before interest expense, interest income, income taxes, depreciation and amortization, certain non-cash charges (including amortization of deferred airborne lease incentives, stock-based compensation expense and adjustment to deferred financing costs) 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.

Canadian ATG Spectrum License	17. 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 March 31, 2016 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 Canadian ATG Years ending December 31, Amortization 2016 (period from April 1 to December 31) $ 75 2017 $ 100 2018 $ 100 2019 $ 100 2020 $ 100 Thereafter $ 1,658 Amortization expense totaled less than $0.1 million during the three month periods ended March 31, 2016 and 2015.
