Notes to Condensed Consolidated Financial Statements

NOTE 1 — ORGANIZATION AND BUSINESS

Organization and Business

GTT Communications, Inc. (“GTT” or the "Company") is a provider of cloud networking services. The Company offers multinational clients a broad portfolio of global communications services including: EtherCloud® wide area network services; Internet services; managed network and security services; and voice and unified communication services.

GTT's global Tier 1 IP network delivers connectivity to clients around the world. The Company provides services to leading multinational enterprises, carriers and government customers.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and should be read in conjunction with the Company’s audited financial statements and footnotes thereto for the fiscal year ended December 31, 2015, included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 filed on March 9, 2016. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been omitted pursuant to such rules and regulations.

The condensed consolidated financial statements reflect all adjustments (consisting primarily of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company’s consolidated financial position and its results of operations. The operating results for the three and six months ended June 30, 2016 are not necessarily indicative of the results to be expected for the full fiscal year 2016 or for any other interim period. The December 31, 2015 consolidated balance sheet is condensed from the audited financial statements as of that date, but does not include all disclosures required by GAAP.

Use of Estimates and Assumptions

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates are used when establishing allowances for doubtful accounts and accruals for billing disputes, determining useful lives for depreciation and amortization and accruals for exit activities, assessing the need for impairment charges (including those related to intangible assets and goodwill), determining the fair values of assets acquired and liabilities assumed in business combinations, accounting for income taxes and related valuation allowances against deferred tax assets and estimating the grant date fair values used to compute the share-based compensation expense. Management evaluates these estimates and judgments on an ongoing basis and makes estimates based on historical experience, current conditions, and various other assumptions that are believed to be reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. Actual results may differ from these estimates under different assumptions or conditions.

Segment Reporting

The Company reports operating results and financial data in one operating and reporting segment. The chief operating decision maker manages the Company as a single profit center in order to promote collaboration, provide comprehensive service offerings across its entire customer base, and provide incentives to employees based on the success of the organization as a whole. Although certain information regarding selected products or services are discussed for purposes of promoting an understanding of the Company's complex business, the chief operating decision maker manages the Company and allocates resources at the consolidated level.

Revenue Recognition

The Company delivers four primary services to its customers — flexible Ethernet-based wide area connectivity services; high bandwidth internet connectivity services; managed network services and security services; and global communication and collaboration services. Certain of its revenue activities have features that may be considered multiple elements, specifically when the Company sells its subscription services in addition to customer premise equipment ("CPE"). The Company believes that there

8

is sufficient evidence to determine each element’s fair value and, as a result, in those arrangements where there are multiple elements, the subscription revenue is recorded ratably over the term of the agreement and the equipment is accounted for as a sale, at the time of sale.

The Company's services are provided under contracts that typically include an installation charge along with payments of recurring charges on a monthly basis for use of the services over a committed term. Its contracts with customers specify the terms and conditions for providing such services, including installation date, recurring and non-recurring fees, payment terms, and contract length. These contracts call for the Company to provide the service in question (e.g., data transmission between point A and point Z), to manage the activation process, and to provide ongoing support (in the form of service maintenance and trouble-shooting) during the service term. The contracts do not typically provide the customer any rights to use specifically identifiable assets. Furthermore, the contracts generally provide the Company with discretion to engineer (or re-engineer) a particular network solution to satisfy each customer’s data transmission requirement, and typically prohibit physical access by the customer to the network infrastructure used by the Company and its suppliers to deliver the services.

The Company recognizes revenue as follows:

Monthly Recurring Revenue. Monthly recurring revenue represents the substantial majority of the Company's revenue, and consists of fees charged for ongoing services that are generally fixed in price and billed on a recurring monthly basis for a specified term. At the end of the term, most contracts provide for a continuation of services on the same terms, either for a specified renewal period (e.g., one year) or on a month-to-month basis. The Company records recurring revenue based on the fees agreed to in each contract, as long as the contract is in effect, and as long as collectability is reasonably assured.

Burst Revenue. Burst revenue represents variable charges for certain services, based on specific usage of those services, or usage above a fixed threshold, billed monthly in arrears. The Company records burst revenue based on actual usage charges billed using the rates and/or thresholds specified in each contract, as long as collectability is reasonably assured.

Non-recurring Revenue. Non-recurring revenue consists of charges for installation in connection with the delivery of recurring communications services, late payments, cancellation fees, early termination fees, and equipment sales. Fees billed for installation services are initially recorded as deferred revenue then recognized ratably over the contractual term of the recurring service. Fees charged for late payments, cancellation (pre-installation) or early termination (post-installation) are typically fixed or determinable per the terms of the respective contract, and are recognized as revenue when billed if collectability is reasonably assured. In addition, from time to time the Company sells communications and/or networking equipment to its customers in connection with its data networking services. The Company recognizes revenue from the sale of equipment at the contracted selling price when title to the equipment passes to the customer (generally F.O.B. origin) and when collectability is reasonably assured.

Universal Service Fund (USF), Gross Receipts Taxes and Other Surcharges

The Company is liable in certain cases for collecting regulatory fees and/or certain sales taxes from its customers and remitting the fees and taxes to the applicable governing authorities. Where the Company collects on behalf of a regulatory agency, the Company does not record any revenue. The Company records applicable taxes on a net basis.

Cost of Telecommunications Services

Cost of telecommunications services includes direct costs incurred in accessing other telecommunications providers’ networks in order to provide telecommunication services to the Company's customers, and expenses for connection to other carriers. The cost of the Company's core network is usually renewed on an annual basis. Connectivity from the Company's core network to a customer premise is typically contracted using matching terms to the customer. Cost of telecommunications services also includes co-location charges, usage-based access charges and professional services fees incurred pursuant to a customer's service contract.

Share-Based Compensation

The Company recognizes share-based compensation expense for share-based payment awards based on the grant date fair value.

The fair value of stock options is determined on the date of grant using the Black-Scholes option-pricing model. The expense is recognized on a straight-line basis over the requisite service period. Share-based compensation expense also includes grants for performance awards. The Company recognizes share-based compensation expense for these grants when the achievement of the performance criteria is considered probable.

9

Income Taxes

Income taxes are accounted for under the asset and liability method pursuant to GAAP. Under this method, deferred tax assets and liabilities are recognized for the expected future results attributable to the differences between the financial statement carrying amounts and the tax basis of assets and liabilities. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the period of the change. Further, deferred tax assets are recognized for the expected realization of available net operating loss and tax credit carryforwards. A valuation allowance is recorded on gross deferred tax assets when it is “more likely than not” that such asset will not be realized. When evaluating the realizability of deferred tax assets, all evidence, both positive and negative is evaluated. Items considered in this analysis include the ability to carry back losses, the reversal of temporary differences, tax planning strategies, and expectations of future earnings. The Company reviews its deferred tax assets on a quarterly basis to determine if a valuation allowance is required based upon these factors. Changes in the Company's assessment of the need for a valuation allowance could give rise to a change in such allowance, potentially resulting in additional expense or benefit in the period of change.

The Company's income tax provision includes U.S. federal, state, local and foreign income taxes and is based on pre-tax income or loss. In determining the annual effective income tax rate, the Company analyzes various factors, including its annual earnings and taxing jurisdictions in which the earnings were generated, the impact of state and local income taxes and its ability to use tax credits and net operating loss carryforwards.

Under GAAP for income taxes, the amount of tax benefit to be recognized is the amount of benefit that is “more likely than not” to be sustained upon examination. The Company analyzes its tax filing positions in all of the U.S. federal, state, local and foreign tax jurisdictions where it is required to file income tax returns, as well as for all open tax years in these jurisdictions. If, based on this analysis, the Company determines that uncertainties in tax positions exist, a liability is established in the consolidated financial statements. The Company recognizes accrued interest and penalties related to unrecognized tax positions in the provision for income taxes.

Comprehensive Income (Loss)

In addition to net income (loss), comprehensive loss includes certain charges or credits to equity occurring other than as a result of transactions with stockholders. For the Company, this consists of foreign currency translation adjustments.

Earnings (Loss) Per Share

Basic earnings (loss) per share is computed by dividing net income or (loss) available to common stockholders by the weighted average number of common shares outstanding. Diluted earnings per share reflect, in periods with earnings and in which they have a dilutive effect, the effect of common shares issuable upon exercise of stock options.

The table below details the calculations of earnings (loss) per share (in thousands, except for share and per share amounts):  

	Three Months Ended June 30,					Six Months Ended June 30,
	2016		2015			2016		2015
Numerator for basic and diluted EPS – earnings available to common stockholders	$	91	$	(11,114	)	$	987	$	(10,047	)
Denominator for basic EPS – weighted average shares	37,065,651		34,835,154			37,016,720		34,392,392
Effect of dilutive securities	612,469		—			558,677		—
Denominator for diluted EPS – weighted average shares	37,678,120		34,835,154			37,575,397		34,392,392
Earnings (loss) per share: basic	$	—	$	(0.32	)	$	0.03	$	(0.29	)
Earnings (loss) per share: diluted	$	—	$	(0.32	)	$	0.03	$	(0.29	)

The anti-dilutive common share items that were excluded in the computation of earnings per share were approximately 128,000 shares as of June 30, 2016. There were 1.4 million anti-dilutive common shares as of June 30, 2015. 

10

Cash and Cash Equivalents

Cash and cash equivalents may include deposits with financial institutions as well as short-term money market instruments, certificates of deposit and debt instruments with maturities of three months or less when purchased.

Accounts Receivable, Net

Accounts receivable balances are stated at amounts due from the customer net of an allowance for doubtful accounts. Credit extended is based on an evaluation of the customer’s financial condition and is granted to qualified customers on an unsecured basis.

The Company, pursuant to its standard service contracts, is entitled to impose a monthly finance charge with respect to amounts that are past due. The Company’s standard terms require payment within 30 days of the date of the invoice. The Company treats invoices as past due when they remain unpaid, in whole or in part, beyond the payment date set forth in the applicable service contract.

The Company determines its allowance for doubtful accounts by considering a number of factors, including the length of time trade receivables are past due, the customer’s payment history, current ability to pay its obligation, and the condition of the general economy and the industry as a whole. Specific reserves are also established on a case-by-case basis by management. Actual bad debts, when determined, reduce the allowance. The Company periodically evaluates the collectability of accounts receivable and writes off accounts after a determination is made that the amounts at issue are no longer likely to be collected, following the exercise of reasonable collection efforts.

Deferred Costs

Installation costs related to provisioning of recurring communications services that the Company incurs from independent third party suppliers, directly attributable and necessary to fulfill a particular service contract, and which would not have been incurred but for the occurrence of that service contract, are recorded as deferred costs and expensed ratably over the contractual term of service in the same manner as the deferred revenue arising from that contract. Based on historical experience, the Company believes the initial contractual term is the best estimate for the period of earnings. If any installation costs exceed the amount of corresponding deferred revenue, the excess cost is recognized in the current period.

Property and Equipment

Property and equipment is stated at cost, net of accumulated depreciation, computed using the straight-line method.Depreciation on these assets is computed over the estimated useful lives of the assets. Assets and liabilities under capital leases are recorded at the lesser of the present value of the aggregate future minimum lease payments or the fair value of the assets under lease. Leasehold improvements and assets under capital leases are amortized over the shorter of the term of the lease, excluding optional extensions, or the useful life. Depreciable lives used by the Company for its classes of assets are as follows:

Furniture and Fixtures	7 years
Network Equipment	5 years
Leasehold Improvements	up to 10 years
Computer Hardware and Software	3-5 years

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, the asset is considered to be impaired. Impairment losses are measured as the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell or dispose.

Software Capitalization

Software development costs include costs to develop software programs to be used solely to meet the Company's internal needs. The Company capitalizes development costs related to these software applications once the preliminary project stage is complete and it is probable that the project will be completed and the software will be used to perform the function intended.The Company capitalized approximately $0.4 million and $0.8 million for developing such software applications during the three and six months ended June 30, 2016. The capitalized costs were not material in 2015.

11

Goodwill and Intangible Assets

The Company assesses goodwill for impairment on at least an annual basis on October 1 unless interim indicators of impairment exist. Goodwill is considered to be impaired when the net book value of a reporting unit exceeds its estimated fair value. The Company operates as a single operating segment and as a single reporting unit for the purpose of evaluating goodwill. On October 1, 2015, the Company performed its annual impairment test of goodwill by comparing its fair value (primarily based on market capitalization) to the carrying value of equity, and concluded that the fair value of the reporting unit was greater than the carrying amount. During the six months ended June 30, 2016 and 2015 the Company did not record any goodwill impairment.

Intangible assets consist of customer relationships, restrictive covenants related to employment agreements, license fees, intellectual property and trade names. Customer relationships, restrictive covenants related to employment agreements and trade names are amortized, on a straight-line basis, over periods of up to seven years. FCC Licenses are accounted for as definite lived intangibles and amortized over the average remaining useful life of such licenses which approximates three years. Intellectual property consisting of know-how related to the SIP trunking platform is amortized over the estimated useful life of ten years. One of the Company's trade names is not amortized, but is tested on at least an annual basis as of October 1 unless interim indicators of impairment exist. The trade name is considered to be impaired when the net book value exceeds its estimated fair value. As of October 1, 2015, the Company performed its annual impairment test of the trade name, and concluded that the fair value of the trade name was greater than the carrying amount. The Company used the relief from royalty method for valuation.

 At the end of the second quarter of 2016, the Company evaluated whether any triggering events had occurred that may require further testing. After assessing the totality of events and circumstances, the Company has determined that there were no indicators that the fair value of goodwill was below its carrying amounts and therefore an interim Step 1 goodwill impairment test was not required to be performed.

Business Combinations

The Company includes the results of operations of the businesses that it acquires commencing on the respective dates of acquisition. The Company allocates the fair value of the purchase price of its acquisitions to the assets acquired and liabilities assumed based on their estimated fair values. The excess of the fair value of the purchase price over the fair values of these identifiable assets and liabilities is recorded as goodwill.

Accrued Supplier Expenses

The Company accrues estimated charges owed to its suppliers for services. The Company bases this accrual on the supplier contract, the individual service order executed with the supplier for that service, and the length of time the service has been active.

Disputed Supplier Expenses

It is common in the telecommunications industry for customers and suppliers to engage in disputes over amounts billed (or not billed) in error or over interpretation of contract terms. Management estimates a liability for the amounts the Company believes are valid and that the Company owes to a supplier. This liability is reconciled with actual results as disputes are resolved, or as the appropriate statute of limitations with respect to a given dispute expires. As of June 30, 2016, the Company had open disputes, not accrued for, of $7.4 million. As of December 31, 2015, the Company had open disputes, not accrued for, of $6.9 million.

Acquisition Earn-outs and Holdbacks

Acquisition earn-outs and holdbacks represent either contingent consideration subject to re-measurement to fair value, or fixed deferred consideration due to be paid out typically on the one-year anniversary of an acquisition's closing.  Contingent consideration is remeasured to fair value at each reporting period. The portion of the deferred consideration due within one year is recorded as a current liability until paid, and any consideration due beyond one year is recorded in other long-term liabilities.

Debt Issuance Costs

Debt issuance costs represent costs that qualify for deferral associated with the issuance of new debt or the modification of existing debt facilities. The unamortized balance of debt issuance costs is presented as a reduction to the carrying value of long-term debt. Debt issuance costs are amortized and recognized on the condensed consolidated statements of operations as interest expense.

Translation of Foreign Currencies

These consolidated financial statements have been reported in U.S. Dollars by translating asset and liability amounts of foreign subsidiaries at the closing exchange rate, equity amounts at historical rates, and the results of operations and cash flow at the average exchange rate prevailing during the periods reported.

Transactions denominated in foreign currencies are recorded at the rates of exchange prevailing at the time of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated at the rate of exchange prevailing at the balance sheet date. Exchange differences arising upon settlement of a transaction are reported in the condensed consolidated statements of operations in other expense, net.

Fair Value Measurements

Accounting guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Under this guidance, the Company is required to classify certain assets and liabilities based on the following hierarchy:

Level 1:    Quoted prices for identical assets or liabilities in active markets that can be assessed at the measurement date.

Level 2:    Inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3:    Inputs reflect management's best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are unobservable in the market and significant to the instruments valuation.

The guidance requires the use of observable market data if such data is available without undue cost and effort.

As of June 30, 2016 and December 31, 2015, the carrying amounts reflected in the accompanying consolidated balance sheets for cash and cash equivalents, accounts receivable, accounts payable, and other liabilities approximated fair value due to the short-term nature of these instruments.

The carrying value of the Company's long-term debt, net of unamortized debt issuance costs and unamortized original issuance discount was $416.9 million and $386.2 million, as of June 30, 2016 and December 31, 2015, respectively. Based on trading activity of the Company's specific debt, the fair value of the Company's long-term debt as of June 30, 2016 and December 31, 2015 was estimated to be the same as its carrying value. The Company's fair value estimates of the long-term debt were based on level 2 inputs; quoted prices for similar instruments in active markets.

The Company recorded an earn-out for an acquisition consummated in 2014 at fair value. The earn-out was fully settled in the second quarter of 2016 at the fair value as of December 31, 2015. The fair value of the earn-out was $0.5 million as of December 31, 2015, which was estimated to be the same as its carrying value, based on level 3 inputs.

Assets and liabilities measured at fair value on a non-recurring basis include goodwill, tangible assets, and intangible assets. Such assets are reviewed quarterly for impairment indicators. If a triggering event has occurred, the assets are re-measured when the estimated fair value of the corresponding asset group is less than the carrying value. The fair value measurements, in such instances, are based on significant unobservable inputs (level 3).

Concentrations of Credit Risk

Financial instruments potentially subject to concentration of credit risk consist primarily of cash and cash equivalents and trade accounts receivable. At times during the periods presented, the Company had funds in excess of $250,000 insured by the U.S. Federal Deposit Insurance Corporation, or in excess of similar Deposit Insurance programs outside of the United States, on deposit at various financial institutions. Management believes the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held.

The Company's trade accounts receivable are generally unsecured and geographically dispersed. No single customer's trade accounts receivable balance as of June 30, 2016 and December 31, 2015 exceeded 4% of the Company's consolidated accounts receivable, net. No single customer accounted for more than 10% of revenue for the six months ended June 30, 2016 and 2015.

Related Party Transactions

From time to time and in the ordinary course of business, the Company engages in contracts with various vendors for certain networking services and equipment, to support the Company's broad range of communication services it provides to its clients. Several members of the Company's Board of Directors have relationships with these vendors that meet the definition of a related party transaction, as described in the Securities and Exchange Commission ("SEC"), Item 404 of Regulation S-K. The majority of these contracts were in place before the Board member joined the Company's Board of Directors, or the contracts were assumed as part of a recent business acquisition. The related party relationships and the contractual obligations paid and received by the Company for the six months ended June 30, 2016 have not materially changed from Fiscal 2015, as disclosed in the Annual Report on Form 10-K for the fiscal year ended December 31, 2015.

As a matter of corporate governance policy and practice, related party transactions are presented and considered by the Audit Committee of the Company's Board of Directors in accordance with the Company's Code of Business Conduct and Ethics, Conflict of Interest Policy.

Newly Adopted Accounting Principles

For information regarding newly adopted accounting principles, please refer to the "Management's Discussion and Analysis of Financial Condition and Results of Operations" contained in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2015 and Note 2 to our consolidated financial statements contained therein. The Company has not adopted any new accounting principles for the second quarter of 2016.

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the existing accounting standards for revenue recognition. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which delays the effective date of ASU 2014-09 by one year. The FASB also agreed to allow entities to choose to adopt the standard as of the original effective date. As such, the updated standard will be effective in the first quarter of 2018, with the option to adopt it in the first quarter of 2017. The Company is still evaluating the effect that the updated standard will have on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases, which will require most leases (with the exception of leases with terms of less than one year) to be recognized on the balance sheet as an asset and a lease liability. Leases will be classified as an operating lease or a financing lease. Operating leases are expensed using the straight-line method whereas financing leases will be treated similarly to a capital lease under the current standard. The new standard will be effective for annual and interim periods, within those fiscal years, beginning after December 15, 2018 but early adoption is permitted. The new standard must be presented using the modified retrospective method beginning with the earliest comparative period presented. The Company is currently evaluating the effect of the new standard on its consolidated financial statements and related disclosures.

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718):Improvements to Employee Share-Based Payment Accounting, which was issued as part of the FASB’s simplification initiative and cover such areas as (i) the recognition of excess tax benefits and deficiencies and the classification of those excess tax benefits on the statement of cash flows, (ii) an accounting policy election for forfeitures to be estimated or account for when incurred, (iii) the amount an employer can withhold to cover income taxes and still qualify for equity classification; and (iv) the classification of those taxes paid on the statement of cash flows. This update is effective for annual and interim periods beginning after December 15, 2016, which will require the Company to adopt these provisions in the first quarter of fiscal 2017. This guidance will be applied either prospectively, retrospectively or using a modified retrospective transition method, depending on the area covered in this update. Early adoption is permitted. The Company is still evaluating the effect of the new standard on its consolidated financial statements and related disclosures.

Other recent accounting pronouncements issued by the FASB during fiscal 2015 and through the period ended June 30, 2016 are not believed by management to have a material impact on the Company's present or historical consolidated financial statements.

Reclassification of Certain Item on Prior Year Presentation

The Company reclassified the amortization of debt issuance costs on the consolidated statement of cash flows for the six months ended June 30, 2015 to match the presentation for the six months ended June 30, 2016. Amortization of debt issuance costs of $0.4

14

million were previously presented as part of changes in other assets, and are now presented as amortization of debt issuance costs. The reclassification had no impact on total revenues, total operating expenses or net income (loss) for any year presented.

NOTE 2 — BUSINESS ACQUISITIONS

Since its formation, the Company has consummated a number of transactions accounted for as business combinations. The acquisitions were executed as part of the Company’s business strategy of expanding through acquisitions. The acquisitions of these businesses have allowed the Company to increase the scale at which it operates, which in turn affords the Company the ability to increase its operating leverage, extend its network, and broaden its customer base.

The accompanying condensed consolidated financial statements include the operations of the acquired entities from their respective acquisition dates. All of the acquisitions have been accounted for as a business combination. Accordingly, consideration paid by the Company to complete the acquisitions is initially allocated to the respective assets and liabilities based upon their estimated fair values as of the date of completion of the acquisition. The recorded amounts for acquired assets and liabilities assumed are provisional and subject to change during the measurement period, which is 12 months from the date of acquisition.

On February 4, 2016, the Company completed the acquisition of Telnes Broadband ("Telnes"), an internet and managed services provider. The Company paid $18.2 million, composed of approximately $15.5 million in cash and $2.7 million in the Company's common stock, valued at the variable weighted average market price per share. Approximately $1.8 million of the cash consideration is deferred for one year to cover undisclosed liabilities or other indemnification claims per the purchase agreement. For the purpose of purchase price allocation, the Company's common stock was valued at $2.0 million due to the lack of marketability. Therefore the purchase consideration for accounting purposes was valued at $17.5 million.

As previously reported, on April 1, 2015, the Company acquired MegaPath Corporation ("MegaPath"). During the three months ended June 30, 2016, the Company and MegaPath settled a dispute related to the closing date net working capital balance, as defined in the purchase agreement. The settlement resulted in the Company paying an additional $4.1 million to the sellers in July 2016. The Company has recorded the $4.1 million as additional goodwill as of June 30, 2016.

For material acquisitions completed during fiscal 2015, 2014, and 2013, please refer to the Note 3 to the consolidated financial statements contained in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2015.

Acquisition Method Accounting Estimates

The Company initially recognizes the assets and liabilities acquired from the aforementioned acquisitions based on its preliminary estimates of their acquisition date fair values. As additional information becomes known concerning the acquired assets and assumed liabilities, management may make adjustments to the opening balance sheet of the acquired company up to the end of the measurement period, which is no longer than a one year period following the acquisition date. The determination of the fair values of the acquired assets and liabilities assumed (and the related determination of estimated lives of depreciable tangible and identifiable intangible assets) requires significant judgment.

Acquisition Related Costs

Acquisition related costs describe the broad category of costs the Company incurs in connection with signed and/or closed acquisitions. There are two types of costs that the Company accounts for:

•Severance, restructuring and other exit costs

•Transaction and integration costs

Severance, restructuring and other exit costs are costs the Company incurs related to non-recurring benefits the Company pays to severed employees, termination charges for leases and supplier contracts, and other costs incurred associated with an exit activity. These costs are reported separately in the condensed consolidated statements of operations during the three and six months ended June 30, 2016. Refer to Note 8 of these Condensed Consolidated Financial Statements for further information on severance, restructuring and other exit costs.

Transaction and integration costs include expenses associated with professional services (i.e., legal, accounting, regulatory, etc.) rendered in connection with signed and/or closed acquisitions, travel expense, and other non-recurring direct expenses incurred that are associated with such acquisitions. Transaction and integration costs are expensed as incurred, included in selling, general and administrative expenses, and may be incurred up to six months after the closing date of acquisition in support of the integration.

15

The Company incurred transaction and integration costs of $1.1 million and $2.4 million during the three and six months ended June 30, 2016.

Pro forma Financial Information (Unaudited)

The pro forma results presented below include the effects of the Company's acquisition of MegaPath and One Source Networks ("OSN") that closed on October 22, 2015, as if the acquisitions occurred on January 1, 2015. The pro forma net income (loss) for the three and six months ended June 30, 2016 and 2015, respectively, includes the additional depreciation and amortization resulting from the adjustments to the value of property, plant and equipment and intangible assets resulting from acquisition accounting and adjustment to amortized revenue during first and second quarters of fiscal 2016 and 2015, respectively, as a result of the acquisition date valuation of assumed deferred revenue. The pro forma results also include interest expense associated with debt used to fund the acquisitions. The pro forma results do not include any anticipated synergies or other expected benefits of the acquisitions. The unaudited pro forma financial information below is not necessarily indicative of either future results of operations or results that might have been achieved had the acquisitions been consummated as of January 1, 2015.

NOTE 3 — GOODWILL AND INTANGIBLE ASSETS

At the end of the second quarter of 2016, the Company evaluated whether any triggering events had occurred that may require further testing. After assessing the totality of events and circumstances, the Company has determined that there were no indicators that the fair value is below its carrying amounts and therefore an interim Step 1 goodwill impairment test was not required to be performed.

In June 2016, the Company completed the purchase of certain customer contracts with average monthly recurring revenue (MRR) of approximately $0.9 million, for total consideration of $13.3 million. $6.0 million of the consideration was paid in June 2016, and the remaining $7.3 million is scheduled to be paid in 2017, subject to certain adjustments. The entire $13.3 million was recognized as an intangible asset and will be amortized over its useful life of five years.

In addition, as described in Note 2, during the three months ended June 30, 2016, the Company settled a dispute related to the acquisition of MegaPath, resulting in an increase to goodwill of $4.1 million.

The goodwill balance was $279.5 million and $271.0 million as of June 30, 2016 and December 31, 2015, respectively. Additionally, the Company's intangible asset balance was $187.9 million and $182.2 million as of June 30, 2016 and December 31, 2015, respectively. The additions to both goodwill and intangible assets during the six months ended June 30, 2016 relate to the asset purchase of customer contracts, the acquisition and purchase price allocation refinement of Telnes, and the asset valuation settlement of MegaPath (see Note 2 - Business Acquisitions).

October 2015 Credit Agreement

On October 22, 2015, the Company entered into a credit agreement (the “October 2015 Credit Agreement”) that provided for a $400.0 million term loan facility and a $50.0 million revolving line of credit (which includes a $15.0 million letter of credit facility and a $10.0 million swingline facility). In addition, the Company may request incremental term loan and/or incremental revolving loan commitments in an aggregate amount not to exceed the sum of $75.0 million and an unlimited amount that is subject to pro forma compliance with certain net secured leverage ratio tests, provided, however, that incremental revolving loan commitments may not exceed $25.0 million.

The term loan facility was issued at a discount of $8 million. The applicable rate for term loans was LIBOR plus 5.25% subject to a LIBOR floor of 1.00%. The applicable rate for revolving loans was LIBOR plus 4.75% with no floor. The maturity date of the term loan facility is October 22, 2022 and the maturity date of the revolving line of credit is October 22, 2020. The Company may prepay loans under the October 2015 Credit Agreement at any time, subject to the “soft call” provision noted below, and subject to certain notice requirements and LIBOR breakage costs.

On May 3, 2016, the Company entered into an incremental term loan agreement which increased outstanding term loans by$30.0 million, the proceeds of which were used to repay the outstanding revolving loans.

On June 28, 2016, the Company entered into Amendment No. 1 (the “Repricing Amendment”) to the October 2015 Credit Agreement. The Repricing Amendment, among other things, reduced the applicable rate for term loans to LIBOR plus4.75% (subject to a LIBOR floor of 1.00%) and reduced the applicable rate for revolving loans to LIBOR plus4.25% (with no LIBOR floor). The Repricing Amendment also includes a “soft call” prepayment penalty of 1.0% through December 28, 2016 for certain prepayments, refinancings, and amendments where the primary purpose is to further reduce the applicable rate.

The Company accounted for the Repricing Amendment as a modification of debt. $1.6 million of prior deferred debt issuance cost was accelerated and recorded as a Loss on Debt Extinguishment in the condensed consolidated statements of operations, attributable to prior syndicate lenders who reduced or eliminated their positions during the amendment process. The Company also incurred $0.8 million of additional debt issuance cost in connection with the Repricing Amendment, which was recorded as an offset to Long-Term Debt in the condensed consolidated balance sheets.

As of June 30, 2016, the Company had outstanding revolving loans of $6.0 million and had $43.5 million of borrowing capacity available under its revolving line of credit. Approximately $0.5 million of the revolving line of credit is currently utilized for outstanding letters of credit relating to the Company’s real estate lease obligations.

The effective interest rate on outstanding debt at June 30, 2016 and December 31, 2015 was6.26%and6.24%, respectively. The aggregate contractual maturities of long-term debt (excluding unamortized discounts and unamortized debt issuance costs) were as follows at June 30, 2016 (amounts in thousands):

	Total Debt
2016 remaining	$	2,150

2020	10,300
2021	4,300
2022	404,275
Total	$	433,925

Debt covenants

The October 2015 Credit Agreement contains customary financial and operating covenants, including among others a consolidated net secured leverage ratio and covenants restricting the incurrence of debt, imposition of liens, the payment of dividends and entering into affiliate transactions. The October 2015 Credit Agreement also contains customary events of default, including nonpayment of principal or interest, material inaccuracy of representations and failure to comply with covenants. If an event of default occurs and is continuing under the October 2015 Credit Agreement, the entire outstanding balance may become immediately due and payable.

In addition, the Company is restricted from permitting the Consolidated Net Secured Leverage Ratio to be greater than the maximum ratio specified below during the period opposite such maximum ratio:

Fiscal Quarter Ending	Maximum Ratio
June 30, 2016	5.00:1.00
September 30, 2016	4.75:1.00
December 31, 2016	4.75:1.00
March 31, 2017	4.50:1.00
June 30, 2017	4.50:1.00
September 30, 2017	4.25:1.00
December 31, 2017	4.25:1.00
March 31, 2018	4.00:1.00
June 30, 2018	4.00:1.00
September 30, 2018	3.75:1.00
December 31, 2018	3.75:1.00
March 31, 2019 and thereafter	3.50:1.00

The Company was in compliance with all financial covenants under the October 2015 Credit Agreement as of June 30, 2016.

Guarantees

The Company's obligations under the October 2015 Credit Agreement are guaranteed by certain of its subsidiaries and secured by substantially all of its tangible and intangible assets.

NOTE 6 — SHARE-BASED COMPENSATION

Share-Based Compensation Plan

The Company grants share-based equity awards, including stock options and restricted stock, pursuant to three plans in effect as of June 30, 2016; the 2006 Plan adopted in October 2006, the 2011 Plan adopted in June 2011, and the 2015 Plan adopted in June 2015 (collectively referred to as the "GTT Stock Plan"). The GTT Stock Plan is limited to an aggregate 9,500,000 shares of which 7,664,762 have been issued and are outstanding as of June 30, 2016.

The GTT Stock Plan permits the granting of stock options, restricted stock and performance awards to employees (including employee directors and officers) and consultants of the Company, and non-employee directors of the Company.

19

Options granted under the GTT Stock Plan have an exercise price of at least 100% of the fair market value of the underlying stock on the grant date and expire no later than 10 years from the grant date. The stock options generally vest over four years with 25% of the options becoming exercisable one year from the date of grant and the remaining 75% annually or quarterly over the following three years.

Restricted stock granted under the GTT Stock Plan is valued at the closing stock price on the day of grant. Restricted stock generally vests over four years with 25% of the shares becoming unrestricted one year from the date of grant and the remaining 75% annually or quarterly over the following three years.

The Company uses the Black-Scholes option-pricing model to determine the fair value of its option awards at the time of grant. The fair value of the restricted stock awards was calculated using the value of GTT common stock on the grant date and is being amortized over the vesting periods in which the restrictions lapse.

Performance awards are restricted shares granted under the GTT Stock Plan subject to the achievement of certain performance measures. Once achievement of these performance measures is considered probable, the Company starts to expense the fair value of the grant over the requisite service period. The performance award is valued at the closing stock price on the day of grant. The performance grant will vest annually or quarterly over the requisite service period once achievement of the performance measure has been met and approved by the Compensation Committee.

The Compensation Committee of the Board of Directors, as administrator of the Plan, has the discretion to authorize a different vesting schedule for any awards.

The following tables summarize the share-based compensation expense recognized as a selling, general and administrative expense in the condensed consolidated statements of operations (amounts in thousands):

	Three months ended June 30,				Six months ended June 30,

¹Compensation expense includes $0.6 million and $0.9 million for the three and six months ended June 30, 2016, respectively, related to the shares issued to the former employees of OSN, which was acquired in 2015, for continued employment, as discussed in more detail below. No such expense was recorded in 2015.

As of June 30, 2016, there was $29.2 million of total unrecognized compensation cost related to unvested share-based compensation agreements. The following table summarizes the unrecognized compensation cost and the weighted average period over which the cost is expected to be amortized (amounts in thousands):

Performance Awards

In 2014, the Company granted $7.8 million of restricted stock contingent upon the achievement of certain performance criteria (the 2014 Performance Awards). The fair value of the 2014 Performance Awards was calculated using the value of GTT common stock on the grant date. The Company started recognizing stock-based compensation expense for these grants once the achievement of the performance criteria was considered probable, which was in the third quarter of 2015. The 2014 Performance Awards started vesting in the fourth quarter of 2015 when the performance criteria were met and they will continue to vest ratably over the subsequent two years. As of June 30, 2016, unamortized compensation cost related to the unvested 2014 Performance Awards was $3.4 million.

In 2015, the Company granted $17.2 million of restricted stock contingent upon the achievement of certain performance criteria (the 2015 Performance Awards). The fair value of the 2015 Performance Awards was calculated using the value of GTT common stock on the grant date. As the achievement of the performance criteria is not yet considered probable, the full $17.2 million remains unamortized as of June 30, 2016 and has been excluded from the tables above.

Shares Issued in Acquisition

In conjunction with the acquisition of OSN, the Company issued $3.6 million, or 289,055 unregistered shares, of common stock to the selling shareholders of OSN subject to a continuing employment period of 18 months. The fair value of this issuance was calculated using the value of GTT common stock on the acquisition date less a discount for lack of marketability. The $3.6 million is being expensed over the 18 month service period. As of June 30, 2016, unamortized compensation expense was $2.0 million and will be recognized over the remaining 9 months.

NOTE 7 — INCOME TAXES

The Company’s provision for income taxes is determined using an estimate of its annual effective tax rate, adjusted for certain items. The quarterly tax provision and estimate of the Company's annual effective tax rate are subject to volatility due to several factors, including the Company's ability to accurately project its income (loss) before provision for income taxes in multiple jurisdictions and the effects of acquisitions and integrations.

For the three months ended June 30, 2016, the Company earned income before taxes of $96 thousand and incurred a tax expense of $5 thousand, which resulted in an effective tax rate of 5.2%, as compared to an effective tax rate of (3.6)% for the three months ended June 30, 2015. The effective tax rate for the three months ended June 30, 2016 differs from the statutory U.S. federal income tax rate of 35.0% primarily due to changes in the amount of income before income taxes between the U.S. and foreign countries. The change in the current quarter effective tax rate compared to prior year was primarily due to the tax impact of US losses in the prior year that did not produce a tax benefit.

For the six months ended June 30, 2016, the Company earned income before taxes of $1.4 million and incurred tax expense of $0.4 million, which resulted in an effective tax rate of 29.3% as compared to an effective tax rate of (0.2)% for the six months ended June 30, 2015. The effective tax rate for the six months ended June 30, 2016 differs from the statutory U.S. federal income tax rate of 35.0% primarily due to state tax expense, foreign tax rate differences and a discrete benefit related to foreign provision-to-return adjustments. The change in the current quarter effective tax rate compared to prior year was primarily due to the tax impact of US losses in the prior year that did not produce a tax benefit.

Realization of deferred tax assets in any jurisdictions depends on various factors, including the expectation of generating sufficient taxable income in that jurisdiction. Although realization is not assured, management believes it is more-likely-than-not that the results of operations will generate sufficient taxable income to support the realization of existing deferred tax assets in the U.S. The Company maintains a valuation allowance against certain foreign deferred tax assets.

NOTE 8 — SEVERANCE, RESTRUCTURING AND OTHER EXIT COSTS

The Company incurred severance, restructuring and other exit costs associated with the acquisitions of MegaPath, OSN and Telnes. These costs include employee severance costs, termination costs associated with facility leases and network agreements, and other exit costs related to the transactions.

During the three months ended March 31, 2016, the Company incurred $1.5 million in charges associated with the acquisition of Telnes. The total exit costs recorded and paid relating to the acquisitions mentioned above are summarized as follows for the three months ended March 31, 2016 (amounts in thousands):

	Balance, December 31, 2015		Charges		Payments			Balance, March 31, 2016

During the three months ended June 30, 2016, the Company did not incur new exit charges. The Company paid $1.8 million in employee termination benefits consisting of $0.9 million related to the acquisition of OSN, and $0.9 million related to the acquisition of Telnes. The total exit costs recorded and paid relating to the acquisitions mentioned above are summarized as follows for the three months ended June 30, 2016 (amounts in thousands):

	Balance, March 31, 2016		Charges	Payments			Balance, June 30, 2016

23

Our customer contracts are generally for initial terms of three years, with some contracts at one year, and others at five years or more. Following the initial terms, these agreements typically provide for automatic renewal for specified periods ranging from one month to one year. Our prices are fixed for the duration of the contract, and we typically bill monthly in advance for such services. If a customer terminates its agreement, the terms of our customer contracts typically require full recovery of any amounts due for the remainder of the term or, at a minimum, our liability to any underlying suppliers.

Our total revenue is comprised of three primary categories that include monthly recurring revenue (or "MRR"), non-recurring revenue, and burst revenue. MRR relates to contracted ongoing service that is generally fixed in price and paid by the customer on a monthly basis for the contracted term. For the three months ended June 30, 2016, MRR was approximately 92% of our total revenue. Non-recurring revenue primarily includes the amortization of previously collected installation and equipment charges to customers; and one-time termination charges for customers who cancel their services prior to the contract termination date. Burst revenue represents variable revenue based on whether a customer exceeds its committed usage threshold as specified in its contract.

Our network supplier contracts do not have any market related net settlement provisions. We have not entered into, and do not plan to enter into, any network supplier contracts which involve financial or derivative instruments. The network supplier contracts are entered into solely for the direct purchase of telecommunications capacity, which is resold by us in the normal course of business. 

Other than cost of telecommunication services provided, our most significant operating expenses are employment costs. As of June 30, 2016, we had 637 full-time equivalent employees. For the three months ended June 30, 2016, the total employee cash compensation and benefits represented approximately 13% of total revenue.

Non-GAAP Financial Measures

In addition to financial measures prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), from time to time we may use or publicly disclose certain "non-GAAP financial measures" in the course of our financial presentations, earnings releases, earnings conference calls, and otherwise. For these purposes, the U.S. Securities and Exchange Commission (“SEC”) defines a "non-GAAP financial measure" as a numerical measure of historical or future financial performance, financial positions, or cash flows that (i) exclude amounts, or is subject to adjustments that effectively exclude amounts, included in the most directly comparable measure calculated and presented in accordance with GAAP in financial statements, and (ii) include amounts, or is subject to adjustments that effectively include amounts, that are excluded from the most directly comparable measure so calculated and presented.

Non-GAAP financial measures are provided as additional information to investors to provide an alternative method for assessing our financial condition and operating results. We believe that these non-GAAP measures, when taken together with our GAAP financial measures, allow us and our investors to better evaluate our performance and profitability. These measures are not in accordance with, or a substitute for, GAAP, and may be different from or inconsistent with non-GAAP financial measures used by other companies. These measures should be used in addition to and in conjunction with results presented in accordance with GAAP, and should not be relied upon to the exclusion of GAAP financial measures.

Pursuant to the requirements of Regulation G, whenever we refer to a non-GAAP financial measure, we will also generally present, the most directly comparable financial measure calculated and presented in accordance with GAAP, along with a reconciliation of the differences between the non-GAAP financial measure we reference with such comparable GAAP financial measure.

Adjusted Earnings before Interest, Taxes, Depreciation and Amortization (“Adjusted EBITDA”)

Adjusted EBITDA is defined by us as income/(loss) before interest, income taxes, depreciation and amortization adjusted to exclude severance, restructuring and other exit costs, acquisition-related transaction and integration costs, losses on extinguishment of debt, share-based compensation, and from time to time, other non-cash or non-recurring items.

We use Adjusted EBITDA to evaluate operating performance, and this financial measure is among the primary measures we use for planning and forecasting future periods. We further believe that the presentation of Adjusted EBITDA is relevant and useful for investors because it allows investors to view results in a manner similar to the method used by management and makes it easier to compare our results with the results of other companies that have different financing and capital structures. In addition, we have debt covenants that are based on a leverage ratio which utilizes a modified EBITDA calculation, as defined in our credit agreement. The modified EBITDA calculation is similar to our definition of Adjusted EBITDA; however it includes the pro forma Adjusted EBITDA of and expected cost synergies from the companies acquired by us during the applicable reporting period. Finally, Adjusted

24

EBITDA results, along with other quantitative and qualitative information, are utilized by management and our compensation committee for purposes of determining bonus payouts to our employees.

Unlevered Free Cash Flow

Unlevered free cash flow is defined as Adjusted EBITDA less purchases of property and equipment, which we also refer to as capital expenditures. We use this measure to evaluate the level of capital expenditures needed to support our revenue and Adjusted EBITDA, and we believe this measure is also used by investors to evaluate us relative to peer companies in the telecommunications industry.

The following is a reconciliation of Adjusted EBITDA and Unlevered Free Cash Flow from Net Income:

	Three Months Ended June 30,						Six Months Ended June 30,

Recent Developments Affecting Our Results

In June 2016, we completed the purchase of certain customer contracts with average MRR of approximately $0.9 million, for total consideration of $13.3 million.  $6.0 million of the consideration was paid in June 2016, and the remaining $7.3 million is scheduled to be paid in 2017, subject to certain adjustments. The entire $13.3 million was recognized as an intangible asset and will be amortized over its useful life of five years.

On May 3, 2016, we entered into an incremental term loan agreement which increased outstanding term loans by $30.0 million, the proceeds of which were used to repay our then outstanding revolving loans. 

On June 28, 2016, we amended the October 2015 Credit Agreement to reduce the applicable rate for term loans and revolving loans by 0.50%.

Critical Accounting Policies and Estimates

Our consolidated financial statements have been prepared in accordance with GAAP. For information regarding our critical accounting policies and estimates, please refer to "Management's Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates" contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 and Note 1 to our consolidated financial statements contained therein.

Revenue

Our revenue increased by $33.8 million, or 35.6%, from $95.1 million for the three months ended June 30, 2015 to $128.9 million for the three months ended June 30, 2016. The increase was primarily due to the acquisitions of OSN and Telnes, as well as organic growth.

On a constant currency basis using the average exchange rates in effect during the three months ended June 30, 2015 revenue would have been higher by $0.3 million for the three months ended June 30, 2016.

26

Cost of Telecommunications Services Provided

Cost of telecommunications services provided increased by $16.8 million, or 32.7%, from $51.5 million for the three months ended June 30, 2015 to $68.3 million for the three months ended June 30, 2016. Consistent with our increase in revenue, the increase in cost of telecommunications services provided was principally driven by the acquisitions of OSN and Telnes, as well as organic growth.

On a constant currency basis using the average exchange rates in effect during the three months ended June 30, 2015, cost of telecommunications services provided would have been higher by $0.1 million for the three months ended June 30, 2016.

Operating Expenses

Selling, General and Administrative Expenses. SG&A expenses increased by $7.0 million to $35.9 million for the three months ended June 30, 2016 compared to the three months ended June 30, 2015. The increase was due primarily to the acquisitions of OSN and Telnes. Additionally, non-cash compensation increased by $2.2 million for the three months ended June 30, 2016 due to the recognition of share-based compensation on performance awards where the performance criteria have been met and certain shares issued in the OSN acquisition. In addition, we incurred $1.1 million and $2.6 million of transaction and integration costs for the three months ended June 30, 2016 and June 30, 2015, respectively.

Severance, Restructuring and Other Exit Costs. There were no charges incurred for the three months ended June 30, 2016. The $7.7 million incurred for the three months ended June 30, 2015 was comprised of severance and lease and network termination expenses associated with the acquisition of MegaPath.

Depreciation and Amortization. Amortization of intangible assets increased $4.3 million or 72.9%, from $5.9 million to $10.2 million for the three months ended June 30, 2016, due to the additional definite-lived intangible assets recorded in the OSN acquisition. Depreciation expense decreased $0.9 million, or 14.1% from $6.4 million to $5.5 million for the three months ended June 30, 2016, primarily due to valuation adjustments recorded during the second quarter of 2016, for assets obtained by acquisition of OSN.

Other Expense. Other expense increased by $3.7 million to $8.9 million for the three months ended June 30, 2016 compared to the three months ended June 30, 2015. This is primarily attributed to higher interest expense due to higher debt levels driven by the acquisitions in 2015.

On a constant currency basis using the average exchange rates in effect during the three months ended June 30, 2015, operating expenses would have been higher by $0.1 million for the three months ended June 30, 2016. Selling, general and administrative expenses are the only operating expenses that would have been impacted by the change in exchange rates.

Six months ended June 30, 2016 compared to six months ended June 30, 2015

Consistent with our increase in revenue, the increase in cost of telecommunications services provided was principally driven by the acquisitions of MegaPath, OSN, Telnes, as well as organic growth.

On a constant currency basis using the average exchange rates in effect during the six months ended June 30, 2015, cost of telecommunications services provided would have been higher by $0.4 million for the six months ended June 30, 2016.

Operating Expenses

Selling, General and Administrative Expenses. SG&A expenses increased by $24.3 million to $68.1 million for the six months ended June 30, 2016 compared to the six months ended June 30, 2015. The increase was due primarily to the acquisitions of MegaPath, OSN, and Telnes. Additionally, non-cash compensation increased by $2.4 million for the six months ended June 30, 2016 due to the recognition of share-based compensation on performance awards where the performance criteria have been met and certain shares

issued in the OSN acquisition. In addition, we incurred $2.4 million of transaction and integration costs during the six months ended June 30, 2016, compared to $2.6 million for the six months ended June 30, 2015.

Severance, Restructuring and Other Exit Costs. Restructuring cost was $1.5 million for the six months ended June 30, 2016, associated with the acquisition of Telnes, and $7.7 million for the six months ended June 30, 2015, related to the acquisition of MegaPath.

Depreciation and Amortization. Amortization of intangible assets increased $9.1 million or 88.4%, from $10.3 million to $19.4 millionfor the six months ended June 30, 2016, due to the additional definite-lived intangible assets recorded in the acquisitions of MegaPath and OSN. Similarly, depreciation expense increased $2.4 million, or 25.0%, from $9.5 million to $11.9 million for the six months ended June 30, 2016, primarily due to the property and equipment acquired in the respective acquisitions.

Other Expense. Other expense increased by $9.7 million to $16.6 million for the six months ended June 30, 2016 compared to the six months ended June 30, 2015. This is primarily attributed to higher interest expense due to higher debt levels driven by the acquisitions in 2015 and 2016.

On a constant currency basis using the average exchange rates in effect during the six months ended June 30, 2015, operating expenses would have been higher by $0.2 million for the six months ended June 30, 2016. Selling, general and administrative expenses are the only operating expenses that would have been impacted by the change in exchange rates.

Liquidity and Capital Resources

Our primary sources of liquidity have been cash provided by operations, equity offerings and debt financing. Our principal uses of cash have been for acquisitions, working capital, capital expenditures, and debt service requirements. We anticipate that our principal uses of cash in the future will be for acquisitions, capital expenditures, working capital, and debt service.

Management monitors cash flow and liquidity requirements on a regular basis, including an analysis of the anticipated working capital requirements for the next 12 months. This analysis assumes our ability to manage expenses, capital expenditures and the anticipated growth of revenue. Should the expected cash flows not be available, management believes it would have the ability to revise its operating plan and make reductions in expenditures.

Our operations or expansion efforts may require substantial additional financial, operational and managerial resources. As of June 30, 2016, we had approximately $15.4 million in cash and cash equivalents, and our current assets were $18.1 million greater than current liabilities. Our current liabilities include $11.8 million of holdback obligations, of which $7.8 million is payable in 2016. In addition, a substantial portion of accrued severance and exit costs totaling $4.4 million is expected to be paid in 2016. We believe that cash currently on hand, expected cash flows from future operations and existing borrowing capacity are sufficient to fund operations for at least the next 12 months, including the scheduled principal repayments of the October 2015 Credit Agreement and the associated interest cost. If our operating performance differs significantly from our forecasts, we may be required to reduce our operating expenses and curtail capital spending, and we may not remain in compliance with our debt covenants. In addition, if we are unable to fully fund our cash requirements through operations and current cash on hand, we may need to obtain additional financing through a combination of equity and debt financings and/or renegotiation of terms of our existing debt. If any such activities become necessary, there can be no assurance that we would be successful in obtaining additional financing or modifying our existing debt terms.

During the six months ended June 30, 2016 and 2015, we made cash payments for interest totaling $13.3 million and $4.6 million, respectively. The increase in interest payments was a result of the October 2015 Credit Agreement as discussed further in Note 5 of Notes to Condensed Consolidated Financial Statements.

The following table summarizes the net cash activities for the three months ended March 31, 2016 and 2015 (amounts in thousands):

Consolidated Statements of Cash Flows Data	Six Months Ended June 30,
	2016			2015
Net cash provided by operating activities	$	19,356		$	9,381
Net cash used in investing activities	(32,039		)	(137,705		)
Net cash provided by financing activities	15,060			97,131

Cash Provided by Operating Activities

Cash provided by operating activities for the six months ended June 30, 2016 and 2015 was $19.4 million and $9.4 million, respectively. Our largest source of cash provided by operating activities is generated by monthly recurring revenue. Our primary uses of cash are payments to network suppliers, compensation related costs and other third party vendors, such as agents, contractors, and professional service providers. Cash provided by operating activities during the six months ended June 30, 2016 included $13.3 million in interest; $2.4 million in transaction and integration costs relating to the acquisitions of OSN and Telnes, and an overall working capital use of approximately $21.8 million. The working capital use was driven by an effort to improve the timeliness of payments to our key vendors, and slower payment timing by some of our larger customers.  We do not expect this level of cash use from working capital to continue going forward. Cash provided by operating activities during the six months ended June 30, 2015 included $4.6 million in interest, and an overall working capital use of $5.9 million.

Cash Used in Investing Activities

Cash used in investing activities was $32.0 million for the six months ended June 30, 2016, consisting primarily of $13.8 million for the Telnes acquisition, $6.0 million of cash used for the purchase of customer contracts, and $12.3 million for capital expenditures. Cash used in investing activities was approximately $137.7 million for the six months ended June 30, 2015, primarily for the acquisition of MegaPath.

We expect to continue to incur annual capital expenditures in the range of 4% - 5% of revenue.

Cash Provided by Financing Activities

Net cash provided by financing activities was $15.1 million for the six months ended June 30, 2016, consisting primarily of $26.9 million in net proceeds from debt issuance under the October 2015 Credit Agreement offset by the payment of holdbacks ($10.4 million), primarily related to the acquisition of MegaPath, and a final earn-out ($0.5 million) from a previous acquisition. Net cash provided by financing activities for the six months ended June 30, 2015 was $97.1 million, consisting primarily of net proceeds from debt issuance related to the MegaPath acquisition.

Off-Balance Sheet Arrangements, Contractual Obligations and Commitments

As of June 30, 2016, the estimated annual commitments for contractual agreements and non-cancelable operating and capital leases have not materially changed from the year ended December 31, 2015, as disclosed in the Company's Annual Report on Form 10-K.

We do not have any off -balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to certain market risks. These risks, which include interest rate risk and foreign currency exchange risk, arise in the normal course of business rather than from trading activities.

Interest Rate Sensitivity

Our exposure to market risk for changes in interest rates is primarily related to our outstanding term loans and revolving loans. As of June 30, 2016, we had $427.9 million and $6.0 million in term loans and revolving loans, respectively. The interest expense associated with our credit facility will vary with market rates, specifically LIBOR.

For purposes of the following hypothetical calculations, we have used the October 2015 Credit Agreement, which carries an interest rate equal to LIBOR plus 4.75%, with a LIBOR floor of 1.0%. Current LIBOR rates are below 1.0%, which means there would not be any impact to our income or cash flows from an increase in LIBOR until LIBOR exceeds 1.0%.  Based on current rates, a hypothetical 100 basis point increase in LIBOR would increase annual interest expense by approximately $3.0 million, which would decrease our income and cash flows by the same amount. A hypothetical increase of LIBOR to 4%, the average historical three-month LIBOR, would increase annual interest expense by approximately $13.2 million, which would decrease our income and cash flows by the same amount.

30

We do not currently use derivative financial instruments and have not entered into any interest rate hedging transactions, but we may do so in the future.

Exchange Rate Sensitivity

Our exposure to market risk for changes in foreign currency rate relates to our global operations. Our consolidated financial statements are denominated in U.S. Dollars, but a portion of our revenue, cost of telecommunications services provided and selling, general and administrative expenses are recorded in the local currency of our foreign subsidiaries. Accordingly, changes in exchange rates between the applicable foreign currency and the U.S. Dollar will affect the translation of each foreign subsidiary’s financial results into U.S. Dollars for purposes of reporting consolidated financial results.

Approximately 14% of our revenues for the three months ended June 30, 2016 are generated by non-US entities, of which 56% is recorded in Euros and the remainder is recorded in GBP. Approximately 10% of our cost of telecommunications services provided and approximately 7% of our selling, general and administrative expenses for the three months ended June 30, 2016 are generated by the same non-US entities.  Therefore, it is highly unlikely that changes in exchange rates would have a material impact on our financial condition or results of operations.

We do not currently use derivative financial instruments and have not entered into any foreign currency hedging transactions, but we may do so in the future.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management carried out an evaluation required by Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), under the supervision of and with the participation of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of our disclosure controls and procedures as defined in Rule 13a-15 and 15d-15 under the Exchange Act (“Disclosure Controls”).

Based on our evaluation, our CEO and CFO concluded that our disclosure controls and procedures are designed at a reasonable assurance level and are effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure.

The CEO and the CFO, with assistance from other members of management, have reviewed the effectiveness of our disclosure controls and procedures as of June 30, 2016, and based on their evaluation, have concluded that the disclosure controls and procedures were effective as of such date.

Changes in Internal Control over Financial Reporting

During the three months ended June 30, 2016, we implemented a new financial accounting system.  In connection with the implementation of this new system, we updated many of the processes and procedures related to our internal control over financial reporting, as needed. We do not believe the implementation of the new system or the corresponding changes in processes and procedures has had or will have a material or adverse effect on our internal control over financing reporting.

Except as otherwise described above, there have been no other changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) as of June 30, 2016, that has materially affected, or is reasonably likely to materially affect our internal control over financial reporting.

31

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

ITEM 1A. RISK FACTORS

There have been no material changes to the risk factors disclosed in Part I, Item 1A, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, as filed with the SEC on March 9, 2016.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

ORGANIZATION AND BUSINESS

ORGANIZATION AND BUSINESS

Organization and Business

GTT Communications, Inc. (“GTT” or the "Company") is a provider of cloud networking services. The Company offers multinational clients a broad portfolio of global communications services including: EtherCloud® wide area network services; Internet services; managed network and security services; and voice and unified communication services.

GTT's global Tier 1 IP network delivers connectivity to clients around the world. The Company provides services to leading multinational enterprises, carriers and government customers.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and should be read in conjunction with the Company’s audited financial statements and footnotes thereto for the fiscal year ended December 31, 2015, included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 filed on March 9, 2016. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been omitted pursuant to such rules and regulations.

The condensed consolidated financial statements reflect all adjustments (consisting primarily of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company’s consolidated financial position and its results of operations. The operating results for the three and six months ended June 30, 2016 are not necessarily indicative of the results to be expected for the full fiscal year 2016 or for any other interim period. The December 31, 2015 consolidated balance sheet is condensed from the audited financial statements as of that date, but does not include all disclosures required by GAAP.

Use of Estimates and Assumptions

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates are used when establishing allowances for doubtful accounts and accruals for billing disputes, determining useful lives for depreciation and amortization and accruals for exit activities, assessing the need for impairment charges (including those related to intangible assets and goodwill), determining the fair values of assets acquired and liabilities assumed in business combinations, accounting for income taxes and related valuation allowances against deferred tax assets and estimating the grant date fair values used to compute the share-based compensation expense. Management evaluates these estimates and judgments on an ongoing basis and makes estimates based on historical experience, current conditions, and various other assumptions that are believed to be reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. Actual results may differ from these estimates under different assumptions or conditions.

Segment Reporting

The Company reports operating results and financial data in one operating and reporting segment. The chief operating decision maker manages the Company as a single profit center in order to promote collaboration, provide comprehensive service offerings across its entire customer base, and provide incentives to employees based on the success of the organization as a whole. Although certain information regarding selected products or services are discussed for purposes of promoting an understanding of the Company's complex business, the chief operating decision maker manages the Company and allocates resources at the consolidated level.

Revenue Recognition

The Company delivers four primary services to its customers — flexible Ethernet-based wide area connectivity services; high bandwidth internet connectivity services; managed network services and security services; and global communication and collaboration services. Certain of its revenue activities have features that may be considered multiple elements, specifically when the Company sells its subscription services in addition to customer premise equipment ("CPE"). The Company believes that there is sufficient evidence to determine each element’s fair value and, as a result, in those arrangements where there are multiple elements, the subscription revenue is recorded ratably over the term of the agreement and the equipment is accounted for as a sale, at the time of sale.

The Company's services are provided under contracts that typically include an installation charge along with payments of recurring charges on a monthly basis for use of the services over a committed term. Its contracts with customers specify the terms and conditions for providing such services, including installation date, recurring and non-recurring fees, payment terms, and contract length. These contracts call for the Company to provide the service in question (e.g., data transmission between point A and point Z), to manage the activation process, and to provide ongoing support (in the form of service maintenance and trouble-shooting) during the service term. The contracts do not typically provide the customer any rights to use specifically identifiable assets. Furthermore, the contracts generally provide the Company with discretion to engineer (or re-engineer) a particular network solution to satisfy each customer’s data transmission requirement, and typically prohibit physical access by the customer to the network infrastructure used by the Company and its suppliers to deliver the services.

The Company recognizes revenue as follows:

Monthly Recurring Revenue. Monthly recurring revenue represents the substantial majority of the Company's revenue, and consists of fees charged for ongoing services that are generally fixed in price and billed on a recurring monthly basis for a specified term. At the end of the term, most contracts provide for a continuation of services on the same terms, either for a specified renewal period (e.g., one year) or on a month-to-month basis. The Company records recurring revenue based on the fees agreed to in each contract, as long as the contract is in effect, and as long as collectability is reasonably assured.

Burst Revenue. Burst revenue represents variable charges for certain services, based on specific usage of those services, or usage above a fixed threshold, billed monthly in arrears. The Company records burst revenue based on actual usage charges billed using the rates and/or thresholds specified in each contract, as long as collectability is reasonably assured.

Non-recurring Revenue. Non-recurring revenue consists of charges for installation in connection with the delivery of recurring communications services, late payments, cancellation fees, early termination fees, and equipment sales. Fees billed for installation services are initially recorded as deferred revenue then recognized ratably over the contractual term of the recurring service. Fees charged for late payments, cancellation (pre-installation) or early termination (post-installation) are typically fixed or determinable per the terms of the respective contract, and are recognized as revenue when billed if collectability is reasonably assured. In addition, from time to time the Company sells communications and/or networking equipment to its customers in connection with its data networking services. The Company recognizes revenue from the sale of equipment at the contracted selling price when title to the equipment passes to the customer (generally F.O.B. origin) and when collectability is reasonably assured.

Universal Service Fund (USF), Gross Receipts Taxes and Other Surcharges

The Company is liable in certain cases for collecting regulatory fees and/or certain sales taxes from its customers and remitting the fees and taxes to the applicable governing authorities. Where the Company collects on behalf of a regulatory agency, the Company does not record any revenue. The Company records applicable taxes on a net basis.

Cost of Telecommunications Services

Cost of telecommunications services includes direct costs incurred in accessing other telecommunications providers’ networks in order to provide telecommunication services to the Company's customers, and expenses for connection to other carriers. The cost of the Company's core network is usually renewed on an annual basis. Connectivity from the Company's core network to a customer premise is typically contracted using matching terms to the customer. Cost of telecommunications services also includes co-location charges, usage-based access charges and professional services fees incurred pursuant to a customer's service contract.

Share-Based Compensation

The Company recognizes share-based compensation expense for share-based payment awards based on the grant date fair value.

The fair value of stock options is determined on the date of grant using the Black-Scholes option-pricing model. The expense is recognized on a straight-line basis over the requisite service period. Share-based compensation expense also includes grants for performance awards. The Company recognizes share-based compensation expense for these grants when the achievement of the performance criteria is considered probable.

Income Taxes

Income taxes are accounted for under the asset and liability method pursuant to GAAP. Under this method, deferred tax assets and liabilities are recognized for the expected future results attributable to the differences between the financial statement carrying amounts and the tax basis of assets and liabilities. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the period of the change. Further, deferred tax assets are recognized for the expected realization of available net operating loss and tax credit carryforwards. A valuation allowance is recorded on gross deferred tax assets when it is “more likely than not” that such asset will not be realized. When evaluating the realizability of deferred tax assets, all evidence, both positive and negative is evaluated. Items considered in this analysis include the ability to carry back losses, the reversal of temporary differences, tax planning strategies, and expectations of future earnings. The Company reviews its deferred tax assets on a quarterly basis to determine if a valuation allowance is required based upon these factors. Changes in the Company's assessment of the need for a valuation allowance could give rise to a change in such allowance, potentially resulting in additional expense or benefit in the period of change.

The Company's income tax provision includes U.S. federal, state, local and foreign income taxes and is based on pre-tax income or loss. In determining the annual effective income tax rate, the Company analyzes various factors, including its annual earnings and taxing jurisdictions in which the earnings were generated, the impact of state and local income taxes and its ability to use tax credits and net operating loss carryforwards.

Under GAAP for income taxes, the amount of tax benefit to be recognized is the amount of benefit that is “more likely than not” to be sustained upon examination. The Company analyzes its tax filing positions in all of the U.S. federal, state, local and foreign tax jurisdictions where it is required to file income tax returns, as well as for all open tax years in these jurisdictions. If, based on this analysis, the Company determines that uncertainties in tax positions exist, a liability is established in the consolidated financial statements. The Company recognizes accrued interest and penalties related to unrecognized tax positions in the provision for income taxes.

Comprehensive Income (Loss)

In addition to net income (loss), comprehensive loss includes certain charges or credits to equity occurring other than as a result of transactions with stockholders. For the Company, this consists of foreign currency translation adjustments.

Earnings (Loss) Per Share

Basic earnings (loss) per share is computed by dividing net income or (loss) available to common stockholders by the weighted average number of common shares outstanding. Diluted earnings per share reflect, in periods with earnings and in which they have a dilutive effect, the effect of common shares issuable upon exercise of stock options.

The table below details the calculations of earnings (loss) per share (in thousands, except for share and per share amounts):  

	Three Months Ended June 30,					Six Months Ended June 30,
	2016		2015			2016		2015
Numerator for basic and diluted EPS – earnings available to common stockholders	$	91	$	(11,114	)	$	987	$	(10,047	)
Denominator for basic EPS – weighted average shares	37,065,651		34,835,154			37,016,720		34,392,392
Effect of dilutive securities	612,469		—			558,677		—
Denominator for diluted EPS – weighted average shares	37,678,120		34,835,154			37,575,397		34,392,392
Earnings (loss) per share: basic	$	—	$	(0.32	)	$	0.03	$	(0.29	)
Earnings (loss) per share: diluted	$	—	$	(0.32	)	$	0.03	$	(0.29	)

The anti-dilutive common share items that were excluded in the computation of earnings per share were approximately 128,000 shares as of June 30, 2016. There were 1.4 million anti-dilutive common shares as of June 30, 2015. 

Cash and Cash Equivalents

Cash and cash equivalents may include deposits with financial institutions as well as short-term money market instruments, certificates of deposit and debt instruments with maturities of three months or less when purchased.

Accounts Receivable, Net

Accounts receivable balances are stated at amounts due from the customer net of an allowance for doubtful accounts. Credit extended is based on an evaluation of the customer’s financial condition and is granted to qualified customers on an unsecured basis.

The Company, pursuant to its standard service contracts, is entitled to impose a monthly finance charge with respect to amounts that are past due. The Company’s standard terms require payment within 30 days of the date of the invoice. The Company treats invoices as past due when they remain unpaid, in whole or in part, beyond the payment date set forth in the applicable service contract.

The Company determines its allowance for doubtful accounts by considering a number of factors, including the length of time trade receivables are past due, the customer’s payment history, current ability to pay its obligation, and the condition of the general economy and the industry as a whole. Specific reserves are also established on a case-by-case basis by management. Actual bad debts, when determined, reduce the allowance. The Company periodically evaluates the collectability of accounts receivable and writes off accounts after a determination is made that the amounts at issue are no longer likely to be collected, following the exercise of reasonable collection efforts.

Deferred Costs

Installation costs related to provisioning of recurring communications services that the Company incurs from independent third party suppliers, directly attributable and necessary to fulfill a particular service contract, and which would not have been incurred but for the occurrence of that service contract, are recorded as deferred costs and expensed ratably over the contractual term of service in the same manner as the deferred revenue arising from that contract. Based on historical experience, the Company believes the initial contractual term is the best estimate for the period of earnings. If any installation costs exceed the amount of corresponding deferred revenue, the excess cost is recognized in the current period.

Property and Equipment

Property and equipment is stated at cost, net of accumulated depreciation, computed using the straight-line method.Depreciation on these assets is computed over the estimated useful lives of the assets. Assets and liabilities under capital leases are recorded at the lesser of the present value of the aggregate future minimum lease payments or the fair value of the assets under lease. Leasehold improvements and assets under capital leases are amortized over the shorter of the term of the lease, excluding optional extensions, or the useful life. Depreciable lives used by the Company for its classes of assets are as follows:

Furniture and Fixtures	7 years
Network Equipment	5 years
Leasehold Improvements	up to 10 years
Computer Hardware and Software	3-5 years

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, the asset is considered to be impaired. Impairment losses are measured as the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell or dispose.

Software Capitalization

Software development costs include costs to develop software programs to be used solely to meet the Company's internal needs. The Company capitalizes development costs related to these software applications once the preliminary project stage is complete and it is probable that the project will be completed and the software will be used to perform the function intended.The Company capitalized approximately $0.4 million and $0.8 million for developing such software applications during the three and six months ended June 30, 2016. The capitalized costs were not material in 2015.

Goodwill and Intangible Assets

The Company assesses goodwill for impairment on at least an annual basis on October 1 unless interim indicators of impairment exist. Goodwill is considered to be impaired when the net book value of a reporting unit exceeds its estimated fair value. The Company operates as a single operating segment and as a single reporting unit for the purpose of evaluating goodwill. On October 1, 2015, the Company performed its annual impairment test of goodwill by comparing its fair value (primarily based on market capitalization) to the carrying value of equity, and concluded that the fair value of the reporting unit was greater than the carrying amount. During the six months ended June 30, 2016 and 2015 the Company did not record any goodwill impairment.

Intangible assets consist of customer relationships, restrictive covenants related to employment agreements, license fees, intellectual property and trade names. Customer relationships, restrictive covenants related to employment agreements and trade names are amortized, on a straight-line basis, over periods of up to seven years. FCC Licenses are accounted for as definite lived intangibles and amortized over the average remaining useful life of such licenses which approximates three years. Intellectual property consisting of know-how related to the SIP trunking platform is amortized over the estimated useful life of ten years. One of the Company's trade names is not amortized, but is tested on at least an annual basis as of October 1 unless interim indicators of impairment exist. The trade name is considered to be impaired when the net book value exceeds its estimated fair value. As of October 1, 2015, the Company performed its annual impairment test of the trade name, and concluded that the fair value of the trade name was greater than the carrying amount. The Company used the relief from royalty method for valuation.

 At the end of the second quarter of 2016, the Company evaluated whether any triggering events had occurred that may require further testing. After assessing the totality of events and circumstances, the Company has determined that there were no indicators that the fair value of goodwill was below its carrying amounts and therefore an interim Step 1 goodwill impairment test was not required to be performed.

Business Combinations

The Company includes the results of operations of the businesses that it acquires commencing on the respective dates of acquisition. The Company allocates the fair value of the purchase price of its acquisitions to the assets acquired and liabilities assumed based on their estimated fair values. The excess of the fair value of the purchase price over the fair values of these identifiable assets and liabilities is recorded as goodwill.

Accrued Supplier Expenses

The Company accrues estimated charges owed to its suppliers for services. The Company bases this accrual on the supplier contract, the individual service order executed with the supplier for that service, and the length of time the service has been active.

Disputed Supplier Expenses

It is common in the telecommunications industry for customers and suppliers to engage in disputes over amounts billed (or not billed) in error or over interpretation of contract terms. Management estimates a liability for the amounts the Company believes are valid and that the Company owes to a supplier. This liability is reconciled with actual results as disputes are resolved, or as the appropriate statute of limitations with respect to a given dispute expires. As of June 30, 2016, the Company had open disputes, not accrued for, of $7.4 million. As of December 31, 2015, the Company had open disputes, not accrued for, of $6.9 million.

Acquisition Earn-outs and Holdbacks

Acquisition earn-outs and holdbacks represent either contingent consideration subject to re-measurement to fair value, or fixed deferred consideration due to be paid out typically on the one-year anniversary of an acquisition's closing.  Contingent consideration is remeasured to fair value at each reporting period. The portion of the deferred consideration due within one year is recorded as a current liability until paid, and any consideration due beyond one year is recorded in other long-term liabilities.

Debt Issuance Costs

Debt issuance costs represent costs that qualify for deferral associated with the issuance of new debt or the modification of existing debt facilities. The unamortized balance of debt issuance costs is presented as a reduction to the carrying value of long-term debt. Debt issuance costs are amortized and recognized on the condensed consolidated statements of operations as interest expense.

Translation of Foreign Currencies

These consolidated financial statements have been reported in U.S. Dollars by translating asset and liability amounts of foreign subsidiaries at the closing exchange rate, equity amounts at historical rates, and the results of operations and cash flow at the average exchange rate prevailing during the periods reported.

Transactions denominated in foreign currencies are recorded at the rates of exchange prevailing at the time of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated at the rate of exchange prevailing at the balance sheet date. Exchange differences arising upon settlement of a transaction are reported in the condensed consolidated statements of operations in other expense, net.

Fair Value Measurements

Accounting guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Under this guidance, the Company is required to classify certain assets and liabilities based on the following hierarchy:

Level 1:    Quoted prices for identical assets or liabilities in active markets that can be assessed at the measurement date.

Level 2:    Inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3:    Inputs reflect management's best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are unobservable in the market and significant to the instruments valuation.

The guidance requires the use of observable market data if such data is available without undue cost and effort.

As of June 30, 2016 and December 31, 2015, the carrying amounts reflected in the accompanying consolidated balance sheets for cash and cash equivalents, accounts receivable, accounts payable, and other liabilities approximated fair value due to the short-term nature of these instruments.

The carrying value of the Company's long-term debt, net of unamortized debt issuance costs and unamortized original issuance discount was $416.9 million and $386.2 million, as of June 30, 2016 and December 31, 2015, respectively. Based on trading activity of the Company's specific debt, the fair value of the Company's long-term debt as of June 30, 2016 and December 31, 2015 was estimated to be the same as its carrying value. The Company's fair value estimates of the long-term debt were based on level 2 inputs; quoted prices for similar instruments in active markets.

The Company recorded an earn-out for an acquisition consummated in 2014 at fair value. The earn-out was fully settled in the second quarter of 2016 at the fair value as of December 31, 2015. The fair value of the earn-out was $0.5 million as of December 31, 2015, which was estimated to be the same as its carrying value, based on level 3 inputs.

Assets and liabilities measured at fair value on a non-recurring basis include goodwill, tangible assets, and intangible assets. Such assets are reviewed quarterly for impairment indicators. If a triggering event has occurred, the assets are re-measured when the estimated fair value of the corresponding asset group is less than the carrying value. The fair value measurements, in such instances, are based on significant unobservable inputs (level 3).

Concentrations of Credit Risk

Financial instruments potentially subject to concentration of credit risk consist primarily of cash and cash equivalents and trade accounts receivable. At times during the periods presented, the Company had funds in excess of $250,000 insured by the U.S. Federal Deposit Insurance Corporation, or in excess of similar Deposit Insurance programs outside of the United States, on deposit at various financial institutions. Management believes the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held.

The Company's trade accounts receivable are generally unsecured and geographically dispersed. No single customer's trade accounts receivable balance as of June 30, 2016 and December 31, 2015 exceeded 4% of the Company's consolidated accounts receivable, net. No single customer accounted for more than 10% of revenue for the six months ended June 30, 2016 and 2015.

Related Party Transactions

From time to time and in the ordinary course of business, the Company engages in contracts with various vendors for certain networking services and equipment, to support the Company's broad range of communication services it provides to its clients. Several members of the Company's Board of Directors have relationships with these vendors that meet the definition of a related party transaction, as described in the Securities and Exchange Commission ("SEC"), Item 404 of Regulation S-K. The majority of these contracts were in place before the Board member joined the Company's Board of Directors, or the contracts were assumed as part of a recent business acquisition. The related party relationships and the contractual obligations paid and received by the Company for the six months ended June 30, 2016 have not materially changed from Fiscal 2015, as disclosed in the Annual Report on Form 10-K for the fiscal year ended December 31, 2015.

As a matter of corporate governance policy and practice, related party transactions are presented and considered by the Audit Committee of the Company's Board of Directors in accordance with the Company's Code of Business Conduct and Ethics, Conflict of Interest Policy.

Newly Adopted Accounting Principles

For information regarding newly adopted accounting principles, please refer to the "Management's Discussion and Analysis of Financial Condition and Results of Operations" contained in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2015 and Note 2 to our consolidated financial statements contained therein. The Company has not adopted any new accounting principles for the second quarter of 2016.

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the existing accounting standards for revenue recognition. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which delays the effective date of ASU 2014-09 by one year. The FASB also agreed to allow entities to choose to adopt the standard as of the original effective date. As such, the updated standard will be effective in the first quarter of 2018, with the option to adopt it in the first quarter of 2017. The Company is still evaluating the effect that the updated standard will have on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases, which will require most leases (with the exception of leases with terms of less than one year) to be recognized on the balance sheet as an asset and a lease liability. Leases will be classified as an operating lease or a financing lease. Operating leases are expensed using the straight-line method whereas financing leases will be treated similarly to a capital lease under the current standard. The new standard will be effective for annual and interim periods, within those fiscal years, beginning after December 15, 2018 but early adoption is permitted. The new standard must be presented using the modified retrospective method beginning with the earliest comparative period presented. The Company is currently evaluating the effect of the new standard on its consolidated financial statements and related disclosures.

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718):Improvements to Employee Share-Based Payment Accounting, which was issued as part of the FASB’s simplification initiative and cover such areas as (i) the recognition of excess tax benefits and deficiencies and the classification of those excess tax benefits on the statement of cash flows, (ii) an accounting policy election for forfeitures to be estimated or account for when incurred, (iii) the amount an employer can withhold to cover income taxes and still qualify for equity classification; and (iv) the classification of those taxes paid on the statement of cash flows. This update is effective for annual and interim periods beginning after December 15, 2016, which will require the Company to adopt these provisions in the first quarter of fiscal 2017. This guidance will be applied either prospectively, retrospectively or using a modified retrospective transition method, depending on the area covered in this update. Early adoption is permitted. The Company is still evaluating the effect of the new standard on its consolidated financial statements and related disclosures.

Other recent accounting pronouncements issued by the FASB during fiscal 2015 and through the period ended June 30, 2016 are not believed by management to have a material impact on the Company's present or historical consolidated financial statements.

Reclassification of Certain Item on Prior Year Presentation

Business Combinations [Abstract]

BUSINESS ACQUISITIONS

BUSINESS ACQUISITIONS

Since its formation, the Company has consummated a number of transactions accounted for as business combinations. The acquisitions were executed as part of the Company’s business strategy of expanding through acquisitions. The acquisitions of these businesses have allowed the Company to increase the scale at which it operates, which in turn affords the Company the ability to increase its operating leverage, extend its network, and broaden its customer base.

The accompanying condensed consolidated financial statements include the operations of the acquired entities from their respective acquisition dates. All of the acquisitions have been accounted for as a business combination. Accordingly, consideration paid by the Company to complete the acquisitions is initially allocated to the respective assets and liabilities based upon their estimated fair values as of the date of completion of the acquisition. The recorded amounts for acquired assets and liabilities assumed are provisional and subject to change during the measurement period, which is 12 months from the date of acquisition.

On February 4, 2016, the Company completed the acquisition of Telnes Broadband ("Telnes"), an internet and managed services provider. The Company paid $18.2 million, composed of approximately $15.5 million in cash and $2.7 million in the Company's common stock, valued at the variable weighted average market price per share. Approximately $1.8 million of the cash consideration is deferred for one year to cover undisclosed liabilities or other indemnification claims per the purchase agreement. For the purpose of purchase price allocation, the Company's common stock was valued at $2.0 million due to the lack of marketability. Therefore the purchase consideration for accounting purposes was valued at $17.5 million.

As previously reported, on April 1, 2015, the Company acquired MegaPath Corporation ("MegaPath"). During the three months ended June 30, 2016, the Company and MegaPath settled a dispute related to the closing date net working capital balance, as defined in the purchase agreement. The settlement resulted in the Company paying an additional $4.1 million to the sellers in July 2016. The Company has recorded the $4.1 million as additional goodwill as of June 30, 2016.

For material acquisitions completed during fiscal 2015, 2014, and 2013, please refer to the Note 3 to the consolidated financial statements contained in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2015.

Acquisition Method Accounting Estimates

The Company initially recognizes the assets and liabilities acquired from the aforementioned acquisitions based on its preliminary estimates of their acquisition date fair values. As additional information becomes known concerning the acquired assets and assumed liabilities, management may make adjustments to the opening balance sheet of the acquired company up to the end of the measurement period, which is no longer than a one year period following the acquisition date. The determination of the fair values of the acquired assets and liabilities assumed (and the related determination of estimated lives of depreciable tangible and identifiable intangible assets) requires significant judgment.

Acquisition Related Costs

Acquisition related costs describe the broad category of costs the Company incurs in connection with signed and/or closed acquisitions. There are two types of costs that the Company accounts for:

•Severance, restructuring and other exit costs

•Transaction and integration costs

Severance, restructuring and other exit costs are costs the Company incurs related to non-recurring benefits the Company pays to severed employees, termination charges for leases and supplier contracts, and other costs incurred associated with an exit activity. These costs are reported separately in the condensed consolidated statements of operations during the three and six months ended June 30, 2016. Refer to Note 8 of these Condensed Consolidated Financial Statements for further information on severance, restructuring and other exit costs.

Transaction and integration costs include expenses associated with professional services (i.e., legal, accounting, regulatory, etc.) rendered in connection with signed and/or closed acquisitions, travel expense, and other non-recurring direct expenses incurred that are associated with such acquisitions. Transaction and integration costs are expensed as incurred, included in selling, general and administrative expenses, and may be incurred up to six months after the closing date of acquisition in support of the integration. The Company incurred transaction and integration costs of $1.1 million and $2.4 million during the three and six months ended June 30, 2016.

Pro forma Financial Information (Unaudited)

The pro forma results presented below include the effects of the Company's acquisition of MegaPath and One Source Networks ("OSN") that closed on October 22, 2015, as if the acquisitions occurred on January 1, 2015. The pro forma net income (loss) for the three and six months ended June 30, 2016 and 2015, respectively, includes the additional depreciation and amortization resulting from the adjustments to the value of property, plant and equipment and intangible assets resulting from acquisition accounting and adjustment to amortized revenue during first and second quarters of fiscal 2016 and 2015, respectively, as a result of the acquisition date valuation of assumed deferred revenue. The pro forma results also include interest expense associated with debt used to fund the acquisitions. The pro forma results do not include any anticipated synergies or other expected benefits of the acquisitions. The unaudited pro forma financial information below is not necessarily indicative of either future results of operations or results that might have been achieved had the acquisitions been consummated as of January 1, 2015.

Goodwill and Intangible Assets Disclosure [Abstract]

GOODWILL AND INTANGIBLE ASSETS

GOODWILL AND INTANGIBLE ASSETS

At the end of the second quarter of 2016, the Company evaluated whether any triggering events had occurred that may require further testing. After assessing the totality of events and circumstances, the Company has determined that there were no indicators that the fair value is below its carrying amounts and therefore an interim Step 1 goodwill impairment test was not required to be performed.

In June 2016, the Company completed the purchase of certain customer contracts with average monthly recurring revenue (MRR) of approximately $0.9 million, for total consideration of $13.3 million. $6.0 million of the consideration was paid in June 2016, and the remaining $7.3 million is scheduled to be paid in 2017, subject to certain adjustments. The entire $13.3 million was recognized as an intangible asset and will be amortized over its useful life of five years.

In addition, as described in Note 2, during the three months ended June 30, 2016, the Company settled a dispute related to the acquisition of MegaPath, resulting in an increase to goodwill of $4.1 million.

The goodwill balance was $279.5 million and $271.0 million as of June 30, 2016 and December 31, 2015, respectively. Additionally, the Company's intangible asset balance was $187.9 million and $182.2 million as of June 30, 2016 and December 31, 2015, respectively. The additions to both goodwill and intangible assets during the six months ended June 30, 2016 relate to the asset purchase of customer contracts, the acquisition and purchase price allocation refinement of Telnes, and the asset valuation settlement of MegaPath (see Note 2 - Business Acquisitions).

The changes in the carrying amount of goodwill for the period ended June 30, 2016 and December 31, 2015 are as follows (amounts in thousands):

October 2015 Credit Agreement

On October 22, 2015, the Company entered into a credit agreement (the “October 2015 Credit Agreement”) that provided for a $400.0 million term loan facility and a $50.0 million revolving line of credit (which includes a $15.0 million letter of credit facility and a $10.0 million swingline facility). In addition, the Company may request incremental term loan and/or incremental revolving loan commitments in an aggregate amount not to exceed the sum of $75.0 million and an unlimited amount that is subject to pro forma compliance with certain net secured leverage ratio tests, provided, however, that incremental revolving loan commitments may not exceed $25.0 million.

The term loan facility was issued at a discount of $8 million. The applicable rate for term loans was LIBOR plus 5.25% subject to a LIBOR floor of 1.00%. The applicable rate for revolving loans was LIBOR plus 4.75% with no floor. The maturity date of the term loan facility is October 22, 2022 and the maturity date of the revolving line of credit is October 22, 2020. The Company may prepay loans under the October 2015 Credit Agreement at any time, subject to the “soft call” provision noted below, and subject to certain notice requirements and LIBOR breakage costs.

On May 3, 2016, the Company entered into an incremental term loan agreement which increased outstanding term loans by$30.0 million, the proceeds of which were used to repay the outstanding revolving loans.

On June 28, 2016, the Company entered into Amendment No. 1 (the “Repricing Amendment”) to the October 2015 Credit Agreement. The Repricing Amendment, among other things, reduced the applicable rate for term loans to LIBOR plus4.75% (subject to a LIBOR floor of 1.00%) and reduced the applicable rate for revolving loans to LIBOR plus4.25% (with no LIBOR floor). The Repricing Amendment also includes a “soft call” prepayment penalty of 1.0% through December 28, 2016 for certain prepayments, refinancings, and amendments where the primary purpose is to further reduce the applicable rate.

The Company accounted for the Repricing Amendment as a modification of debt. $1.6 million of prior deferred debt issuance cost was accelerated and recorded as a Loss on Debt Extinguishment in the condensed consolidated statements of operations, attributable to prior syndicate lenders who reduced or eliminated their positions during the amendment process. The Company also incurred $0.8 million of additional debt issuance cost in connection with the Repricing Amendment, which was recorded as an offset to Long-Term Debt in the condensed consolidated balance sheets.

As of June 30, 2016, the Company had outstanding revolving loans of $6.0 million and had $43.5 million of borrowing capacity available under its revolving line of credit. Approximately $0.5 million of the revolving line of credit is currently utilized for outstanding letters of credit relating to the Company’s real estate lease obligations.

The effective interest rate on outstanding debt at June 30, 2016 and December 31, 2015 was6.26%and6.24%, respectively. The aggregate contractual maturities of long-term debt (excluding unamortized discounts and unamortized debt issuance costs) were as follows at June 30, 2016 (amounts in thousands):

	Total Debt
2016 remaining	$	2,150
2017	4,300

2021	4,300
2022	404,275
Total	$	433,925

Debt covenants

The October 2015 Credit Agreement contains customary financial and operating covenants, including among others a consolidated net secured leverage ratio and covenants restricting the incurrence of debt, imposition of liens, the payment of dividends and entering into affiliate transactions. The October 2015 Credit Agreement also contains customary events of default, including nonpayment of principal or interest, material inaccuracy of representations and failure to comply with covenants. If an event of default occurs and is continuing under the October 2015 Credit Agreement, the entire outstanding balance may become immediately due and payable.

In addition, the Company is restricted from permitting the Consolidated Net Secured Leverage Ratio to be greater than the maximum ratio specified below during the period opposite such maximum ratio:

Fiscal Quarter Ending	Maximum Ratio

SHARE-BASED COMPENSATION

SHARE-BASED COMPENSATION

Share-Based Compensation Plan

The Company grants share-based equity awards, including stock options and restricted stock, pursuant to three plans in effect as of June 30, 2016; the 2006 Plan adopted in October 2006, the 2011 Plan adopted in June 2011, and the 2015 Plan adopted in June 2015 (collectively referred to as the "GTT Stock Plan"). The GTT Stock Plan is limited to an aggregate 9,500,000 shares of which 7,664,762 have been issued and are outstanding as of June 30, 2016.

The GTT Stock Plan permits the granting of stock options, restricted stock and performance awards to employees (including employee directors and officers) and consultants of the Company, and non-employee directors of the Company.

Options granted under the GTT Stock Plan have an exercise price of at least 100% of the fair market value of the underlying stock on the grant date and expire no later than 10 years from the grant date. The stock options generally vest over four years with 25% of the options becoming exercisable one year from the date of grant and the remaining 75% annually or quarterly over the following three years.

Restricted stock granted under the GTT Stock Plan is valued at the closing stock price on the day of grant. Restricted stock generally vests over four years with 25% of the shares becoming unrestricted one year from the date of grant and the remaining 75% annually or quarterly over the following three years.

The Company uses the Black-Scholes option-pricing model to determine the fair value of its option awards at the time of grant. The fair value of the restricted stock awards was calculated using the value of GTT common stock on the grant date and is being amortized over the vesting periods in which the restrictions lapse.

Performance awards are restricted shares granted under the GTT Stock Plan subject to the achievement of certain performance measures. Once achievement of these performance measures is considered probable, the Company starts to expense the fair value of the grant over the requisite service period. The performance award is valued at the closing stock price on the day of grant. The performance grant will vest annually or quarterly over the requisite service period once achievement of the performance measure has been met and approved by the Compensation Committee.

The Compensation Committee of the Board of Directors, as administrator of the Plan, has the discretion to authorize a different vesting schedule for any awards.

The following tables summarize the share-based compensation expense recognized as a selling, general and administrative expense in the condensed consolidated statements of operations (amounts in thousands):

	Three months ended June 30,				Six months ended June 30,
	2016		2015		2016		2015

¹Compensation expense includes $0.6 million and $0.9 million for the three and six months ended June 30, 2016, respectively, related to the shares issued to the former employees of OSN, which was acquired in 2015, for continued employment, as discussed in more detail below. No such expense was recorded in 2015.

As of June 30, 2016, there was $29.2 million of total unrecognized compensation cost related to unvested share-based compensation agreements. The following table summarizes the unrecognized compensation cost and the weighted average period over which the cost is expected to be amortized (amounts in thousands):

Fair value of restricted stock granted	$	919	$	4,662	$	7,288	$	6,077

Performance Awards

In 2014, the Company granted $7.8 million of restricted stock contingent upon the achievement of certain performance criteria (the 2014 Performance Awards). The fair value of the 2014 Performance Awards was calculated using the value of GTT common stock on the grant date. The Company started recognizing stock-based compensation expense for these grants once the achievement of the performance criteria was considered probable, which was in the third quarter of 2015. The 2014 Performance Awards started vesting in the fourth quarter of 2015 when the performance criteria were met and they will continue to vest ratably over the subsequent two years. As of June 30, 2016, unamortized compensation cost related to the unvested 2014 Performance Awards was $3.4 million.

In 2015, the Company granted $17.2 million of restricted stock contingent upon the achievement of certain performance criteria (the 2015 Performance Awards). The fair value of the 2015 Performance Awards was calculated using the value of GTT common stock on the grant date. As the achievement of the performance criteria is not yet considered probable, the full $17.2 million remains unamortized as of June 30, 2016 and has been excluded from the tables above.

Shares Issued in Acquisition

In conjunction with the acquisition of OSN, the Company issued $3.6 million, or 289,055 unregistered shares, of common stock to the selling shareholders of OSN subject to a continuing employment period of 18 months. The fair value of this issuance was calculated using the value of GTT common stock on the acquisition date less a discount for lack of marketability. The $3.6 million is being expensed over the 18 month service period. As of June 30, 2016, unamortized compensation expense was $2.0 million and will be recognized over the remaining 9 months.

INCOME TAXES

Income Tax Disclosure [Abstract]

INCOME TAXES

INCOME TAXES

The Company’s provision for income taxes is determined using an estimate of its annual effective tax rate, adjusted for certain items. The quarterly tax provision and estimate of the Company's annual effective tax rate are subject to volatility due to several factors, including the Company's ability to accurately project its income (loss) before provision for income taxes in multiple jurisdictions and the effects of acquisitions and integrations.

For the three months ended June 30, 2016, the Company earned income before taxes of $96 thousand and incurred a tax expense of $5 thousand, which resulted in an effective tax rate of 5.2%, as compared to an effective tax rate of (3.6)% for the three months ended June 30, 2015. The effective tax rate for the three months ended June 30, 2016 differs from the statutory U.S. federal income tax rate of 35.0% primarily due to changes in the amount of income before income taxes between the U.S. and foreign countries. The change in the current quarter effective tax rate compared to prior year was primarily due to the tax impact of US losses in the prior year that did not produce a tax benefit.

For the six months ended June 30, 2016, the Company earned income before taxes of $1.4 million and incurred tax expense of $0.4 million, which resulted in an effective tax rate of 29.3% as compared to an effective tax rate of (0.2)% for the six months ended June 30, 2015. The effective tax rate for the six months ended June 30, 2016 differs from the statutory U.S. federal income tax rate of 35.0% primarily due to state tax expense, foreign tax rate differences and a discrete benefit related to foreign provision-to-return adjustments. The change in the current quarter effective tax rate compared to prior year was primarily due to the tax impact of US losses in the prior year that did not produce a tax benefit.

Realization of deferred tax assets in any jurisdictions depends on various factors, including the expectation of generating sufficient taxable income in that jurisdiction. Although realization is not assured, management believes it is more-likely-than-not that the results of operations will generate sufficient taxable income to support the realization of existing deferred tax assets in the U.S. The Company maintains a valuation allowance against certain foreign deferred tax assets.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and should be read in conjunction with the Company’s audited financial statements and footnotes thereto for the fiscal year ended December 31, 2015, included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 filed on March 9, 2016. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been omitted pursuant to such rules and regulations.

The condensed consolidated financial statements reflect all adjustments (consisting primarily of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company’s consolidated financial position and its results of operations. The operating results for the three and six months ended June 30, 2016 are not necessarily indicative of the results to be expected for the full fiscal year 2016 or for any other interim period. The December 31, 2015 consolidated balance sheet is condensed from the audited financial statements as of that date, but does not include all disclosures required by GAAP.

Use of Estimates and Assumptions

Use of Estimates and Assumptions

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates are used when establishing allowances for doubtful accounts and accruals for billing disputes, determining useful lives for depreciation and amortization and accruals for exit activities, assessing the need for impairment charges (including those related to intangible assets and goodwill), determining the fair values of assets acquired and liabilities assumed in business combinations, accounting for income taxes and related valuation allowances against deferred tax assets and estimating the grant date fair values used to compute the share-based compensation expense. Management evaluates these estimates and judgments on an ongoing basis and makes estimates based on historical experience, current conditions, and various other assumptions that are believed to be reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. Actual results may differ from these estimates under different assumptions or conditions.

Segment Reporting

Segment Reporting

The Company reports operating results and financial data in one operating and reporting segment. The chief operating decision maker manages the Company as a single profit center in order to promote collaboration, provide comprehensive service offerings across its entire customer base, and provide incentives to employees based on the success of the organization as a whole. Although certain information regarding selected products or services are discussed for purposes of promoting an understanding of the Company's complex business, the chief operating decision maker manages the Company and allocates resources at the consolidated level.

Revenue Recognition

Revenue Recognition

The Company delivers four primary services to its customers — flexible Ethernet-based wide area connectivity services; high bandwidth internet connectivity services; managed network services and security services; and global communication and collaboration services. Certain of its revenue activities have features that may be considered multiple elements, specifically when the Company sells its subscription services in addition to customer premise equipment ("CPE"). The Company believes that there is sufficient evidence to determine each element’s fair value and, as a result, in those arrangements where there are multiple elements, the subscription revenue is recorded ratably over the term of the agreement and the equipment is accounted for as a sale, at the time of sale.

The Company's services are provided under contracts that typically include an installation charge along with payments of recurring charges on a monthly basis for use of the services over a committed term. Its contracts with customers specify the terms and conditions for providing such services, including installation date, recurring and non-recurring fees, payment terms, and contract length. These contracts call for the Company to provide the service in question (e.g., data transmission between point A and point Z), to manage the activation process, and to provide ongoing support (in the form of service maintenance and trouble-shooting) during the service term. The contracts do not typically provide the customer any rights to use specifically identifiable assets. Furthermore, the contracts generally provide the Company with discretion to engineer (or re-engineer) a particular network solution to satisfy each customer’s data transmission requirement, and typically prohibit physical access by the customer to the network infrastructure used by the Company and its suppliers to deliver the services.

The Company recognizes revenue as follows:

Monthly Recurring Revenue. Monthly recurring revenue represents the substantial majority of the Company's revenue, and consists of fees charged for ongoing services that are generally fixed in price and billed on a recurring monthly basis for a specified term. At the end of the term, most contracts provide for a continuation of services on the same terms, either for a specified renewal period (e.g., one year) or on a month-to-month basis. The Company records recurring revenue based on the fees agreed to in each contract, as long as the contract is in effect, and as long as collectability is reasonably assured.

Burst Revenue. Burst revenue represents variable charges for certain services, based on specific usage of those services, or usage above a fixed threshold, billed monthly in arrears. The Company records burst revenue based on actual usage charges billed using the rates and/or thresholds specified in each contract, as long as collectability is reasonably assured.

Non-recurring Revenue. Non-recurring revenue consists of charges for installation in connection with the delivery of recurring communications services, late payments, cancellation fees, early termination fees, and equipment sales. Fees billed for installation services are initially recorded as deferred revenue then recognized ratably over the contractual term of the recurring service. Fees charged for late payments, cancellation (pre-installation) or early termination (post-installation) are typically fixed or determinable per the terms of the respective contract, and are recognized as revenue when billed if collectability is reasonably assured. In addition, from time to time the Company sells communications and/or networking equipment to its customers in connection with its data networking services. The Company recognizes revenue from the sale of equipment at the contracted selling price when title to the equipment passes to the customer (generally F.O.B. origin) and when collectability is reasonably assured.

Share-Based Compensation

Share-Based Compensation

The Company recognizes share-based compensation expense for share-based payment awards based on the grant date fair value.

The fair value of stock options is determined on the date of grant using the Black-Scholes option-pricing model. The expense is recognized on a straight-line basis over the requisite service period. Share-based compensation expense also includes grants for performance awards. The Company recognizes share-based compensation expense for these grants when the achievement of the performance criteria is considered probable.

Income Taxes

Income Taxes

Income taxes are accounted for under the asset and liability method pursuant to GAAP. Under this method, deferred tax assets and liabilities are recognized for the expected future results attributable to the differences between the financial statement carrying amounts and the tax basis of assets and liabilities. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the period of the change. Further, deferred tax assets are recognized for the expected realization of available net operating loss and tax credit carryforwards. A valuation allowance is recorded on gross deferred tax assets when it is “more likely than not” that such asset will not be realized. When evaluating the realizability of deferred tax assets, all evidence, both positive and negative is evaluated. Items considered in this analysis include the ability to carry back losses, the reversal of temporary differences, tax planning strategies, and expectations of future earnings. The Company reviews its deferred tax assets on a quarterly basis to determine if a valuation allowance is required based upon these factors. Changes in the Company's assessment of the need for a valuation allowance could give rise to a change in such allowance, potentially resulting in additional expense or benefit in the period of change.

The Company's income tax provision includes U.S. federal, state, local and foreign income taxes and is based on pre-tax income or loss. In determining the annual effective income tax rate, the Company analyzes various factors, including its annual earnings and taxing jurisdictions in which the earnings were generated, the impact of state and local income taxes and its ability to use tax credits and net operating loss carryforwards.

Under GAAP for income taxes, the amount of tax benefit to be recognized is the amount of benefit that is “more likely than not” to be sustained upon examination. The Company analyzes its tax filing positions in all of the U.S. federal, state, local and foreign tax jurisdictions where it is required to file income tax returns, as well as for all open tax years in these jurisdictions. If, based on this analysis, the Company determines that uncertainties in tax positions exist, a liability is established in the consolidated financial statements. The Company recognizes accrued interest and penalties related to unrecognized tax positions in the provision for income taxes.

Comprehensive Income (Loss)

Comprehensive Income (Loss)

In addition to net income (loss), comprehensive loss includes certain charges or credits to equity occurring other than as a result of transactions with stockholders. For the Company, this consists of foreign currency translation adjustments.

Earnings (Loss) Per Share

Earnings (Loss) Per Share

Basic earnings (loss) per share is computed by dividing net income or (loss) available to common stockholders by the weighted average number of common shares outstanding. Diluted earnings per share reflect, in periods with earnings and in which they have a dilutive effect, the effect of common shares issuable upon exercise of stock options.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents may include deposits with financial institutions as well as short-term money market instruments, certificates of deposit and debt instruments with maturities of three months or less when purchased

Accounts Receivable, Net

Accounts Receivable, Net

Accounts receivable balances are stated at amounts due from the customer net of an allowance for doubtful accounts. Credit extended is based on an evaluation of the customer’s financial condition and is granted to qualified customers on an unsecured basis.

The Company, pursuant to its standard service contracts, is entitled to impose a monthly finance charge with respect to amounts that are past due. The Company’s standard terms require payment within 30 days of the date of the invoice. The Company treats invoices as past due when they remain unpaid, in whole or in part, beyond the payment date set forth in the applicable service contract.

The Company determines its allowance for doubtful accounts by considering a number of factors, including the length of time trade receivables are past due, the customer’s payment history, current ability to pay its obligation, and the condition of the general economy and the industry as a whole. Specific reserves are also established on a case-by-case basis by management. Actual bad debts, when determined, reduce the allowance. The Company periodically evaluates the collectability of accounts receivable and writes off accounts after a determination is made that the amounts at issue are no longer likely to be collected, following the exercise of reasonable collection efforts.

Deferred Costs and Debt Issuance Costs

Debt Issuance Costs

Debt issuance costs represent costs that qualify for deferral associated with the issuance of new debt or the modification of existing debt facilities. The unamortized balance of debt issuance costs is presented as a reduction to the carrying value of long-term debt. Debt issuance costs are amortized and recognized on the condensed consolidated statements of operations as interest expense.

Deferred Costs

Installation costs related to provisioning of recurring communications services that the Company incurs from independent third party suppliers, directly attributable and necessary to fulfill a particular service contract, and which would not have been incurred but for the occurrence of that service contract, are recorded as deferred costs and expensed ratably over the contractual term of service in the same manner as the deferred revenue arising from that contract. Based on historical experience, the Company believes the initial contractual term is the best estimate for the period of earnings. If any installation costs exceed the amount of corresponding deferred revenue, the excess cost is recognized in the current period.

Property and Equipment

Property and Equipment

Property and equipment is stated at cost, net of accumulated depreciation, computed using the straight-line method.Depreciation on these assets is computed over the estimated useful lives of the assets. Assets and liabilities under capital leases are recorded at the lesser of the present value of the aggregate future minimum lease payments or the fair value of the assets under lease. Leasehold improvements and assets under capital leases are amortized over the shorter of the term of the lease, excluding optional extensions, or the useful life. Depreciable lives used by the Company for its classes of assets are as follows:

Furniture and Fixtures	7 years
Network Equipment	5 years
Leasehold Improvements	up to 10 years
Computer Hardware and Software	3-5 years

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, the asset is considered to be impaired. Impairment losses are measured as the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell or dispose.

Software Capitalization

Software Capitalization

Software development costs include costs to develop software programs to be used solely to meet the Company's internal needs. The Company capitalizes development costs related to these software applications once the preliminary project stage is complete and it is probable that the project will be completed and the software will be used to perform the function intended.

Goodwill

The Company assesses goodwill for impairment on at least an annual basis on October 1 unless interim indicators of impairment exist. Goodwill is considered to be impaired when the net book value of a reporting unit exceeds its estimated fair value. The Company operates as a single operating segment and as a single reporting unit for the purpose of evaluating goodwill. On October 1, 2015, the Company performed its annual impairment test of goodwill by comparing its fair value (primarily based on market capitalization) to the carrying value of equity, and concluded that the fair value of the reporting unit was greater than the carrying amount.

Intangible Assets

Intangible assets consist of customer relationships, restrictive covenants related to employment agreements, license fees, intellectual property and trade names. Customer relationships, restrictive covenants related to employment agreements and trade names are amortized, on a straight-line basis, over periods of up to seven years. FCC Licenses are accounted for as definite lived intangibles and amortized over the average remaining useful life of such licenses which approximates three years. Intellectual property consisting of know-how related to the SIP trunking platform is amortized over the estimated useful life of ten years. One of the Company's trade names is not amortized, but is tested on at least an annual basis as of October 1 unless interim indicators of impairment exist. The trade name is considered to be impaired when the net book value exceeds its estimated fair value. As of October 1, 2015, the Company performed its annual impairment test of the trade name, and concluded that the fair value of the trade name was greater than the carrying amount. The Company used the relief from royalty method for valuation.

 At the end of the second quarter of 2016, the Company evaluated whether any triggering events had occurred that may require further testing. After assessing the totality of events and circumstances, the Company has determined that there were no indicators that the fair value of goodwill was below its carrying amounts and therefore an interim Step 1 goodwill impairment test was not required to be performed.

Business Combinations

Business Combinations

The Company includes the results of operations of the businesses that it acquires commencing on the respective dates of acquisition. The Company allocates the fair value of the purchase price of its acquisitions to the assets acquired and liabilities assumed based on their estimated fair values. The excess of the fair value of the purchase price over the fair values of these identifiable assets and liabilities is recorded as goodwill.

Accrued Supplier Expenses

Accrued Supplier Expenses

The Company accrues estimated charges owed to its suppliers for services. The Company bases this accrual on the supplier contract, the individual service order executed with the supplier for that service, and the length of time the service has been active.

Disputed Supplier Expenses

Disputed Supplier Expenses

It is common in the telecommunications industry for customers and suppliers to engage in disputes over amounts billed (or not billed) in error or over interpretation of contract terms. Management estimates a liability for the amounts the Company believes are valid and that the Company owes to a supplier. This liability is reconciled with actual results as disputes are resolved, or as the appropriate statute of limitations with respect to a given dispute expires.

Acquisition Earn-outs and Holdbacks

Acquisition Earn-outs and Holdbacks

Acquisition earn-outs and holdbacks represent either contingent consideration subject to re-measurement to fair value, or fixed deferred consideration due to be paid out typically on the one-year anniversary of an acquisition's closing.  Contingent consideration is remeasured to fair value at each reporting period. The portion of the deferred consideration due within one year is recorded as a current liability until paid, and any consideration due beyond one year is recorded in other long-term liabilities.

Translation of Foreign Currencies

Translation of Foreign Currencies

These consolidated financial statements have been reported in U.S. Dollars by translating asset and liability amounts of foreign subsidiaries at the closing exchange rate, equity amounts at historical rates, and the results of operations and cash flow at the average exchange rate prevailing during the periods reported.

Transactions denominated in foreign currencies are recorded at the rates of exchange prevailing at the time of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated at the rate of exchange prevailing at the balance sheet date. Exchange differences arising upon settlement of a transaction are reported in the condensed consolidated statements of operations in other expense, net.

Fair Value Measurements

Fair Value Measurements

Accounting guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Under this guidance, the Company is required to classify certain assets and liabilities based on the following hierarchy:

Level 1:    Quoted prices for identical assets or liabilities in active markets that can be assessed at the measurement date.

Level 2:    Inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3:    Inputs reflect management's best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are unobservable in the market and significant to the instruments valuation.

The guidance requires the use of observable market data if such data is available without undue cost and effort.

As of June 30, 2016 and December 31, 2015, the carrying amounts reflected in the accompanying consolidated balance sheets for cash and cash equivalents, accounts receivable, accounts payable, and other liabilities approximated fair value due to the short-term nature of these instruments.

The carrying value of the Company's long-term debt, net of unamortized debt issuance costs and unamortized original issuance discount was $416.9 million and $386.2 million, as of June 30, 2016 and December 31, 2015, respectively. Based on trading activity of the Company's specific debt, the fair value of the Company's long-term debt as of June 30, 2016 and December 31, 2015 was estimated to be the same as its carrying value. The Company's fair value estimates of the long-term debt were based on level 2 inputs; quoted prices for similar instruments in active markets.

The Company recorded an earn-out for an acquisition consummated in 2014 at fair value. The earn-out was fully settled in the second quarter of 2016 at the fair value as of December 31, 2015. The fair value of the earn-out was $0.5 million as of December 31, 2015, which was estimated to be the same as its carrying value, based on level 3 inputs.

Assets and liabilities measured at fair value on a non-recurring basis include goodwill, tangible assets, and intangible assets. Such assets are reviewed quarterly for impairment indicators. If a triggering event has occurred, the assets are re-measured when the estimated fair value of the corresponding asset group is less than the carrying value. The fair value measurements, in such instances, are based on significant unobservable inputs (level 3).

Concentrations of Credit Risk

Concentrations of Credit Risk

Financial instruments potentially subject to concentration of credit risk consist primarily of cash and cash equivalents and trade accounts receivable. At times during the periods presented, the Company had funds in excess of $250,000 insured by the U.S. Federal Deposit Insurance Corporation, or in excess of similar Deposit Insurance programs outside of the United States, on deposit at various financial institutions. Management believes the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held.

The Company's trade accounts receivable are generally unsecured and geographically dispersed.

Newly Adopted Accounting Principles and Recent Accounting Pronouncements

Newly Adopted Accounting Principles

For information regarding newly adopted accounting principles, please refer to the "Management's Discussion and Analysis of Financial Condition and Results of Operations" contained in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2015 and Note 2 to our consolidated financial statements contained therein. The Company has not adopted any new accounting principles for the second quarter of 2016.

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the existing accounting standards for revenue recognition. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which delays the effective date of ASU 2014-09 by one year. The FASB also agreed to allow entities to choose to adopt the standard as of the original effective date. As such, the updated standard will be effective in the first quarter of 2018, with the option to adopt it in the first quarter of 2017. The Company is still evaluating the effect that the updated standard will have on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases, which will require most leases (with the exception of leases with terms of less than one year) to be recognized on the balance sheet as an asset and a lease liability. Leases will be classified as an operating lease or a financing lease. Operating leases are expensed using the straight-line method whereas financing leases will be treated similarly to a capital lease under the current standard. The new standard will be effective for annual and interim periods, within those fiscal years, beginning after December 15, 2018 but early adoption is permitted. The new standard must be presented using the modified retrospective method beginning with the earliest comparative period presented. The Company is currently evaluating the effect of the new standard on its consolidated financial statements and related disclosures.

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718):Improvements to Employee Share-Based Payment Accounting, which was issued as part of the FASB’s simplification initiative and cover such areas as (i) the recognition of excess tax benefits and deficiencies and the classification of those excess tax benefits on the statement of cash flows, (ii) an accounting policy election for forfeitures to be estimated or account for when incurred, (iii) the amount an employer can withhold to cover income taxes and still qualify for equity classification; and (iv) the classification of those taxes paid on the statement of cash flows. This update is effective for annual and interim periods beginning after December 15, 2016, which will require the Company to adopt these provisions in the first quarter of fiscal 2017. This guidance will be applied either prospectively, retrospectively or using a modified retrospective transition method, depending on the area covered in this update. Early adoption is permitted. The Company is still evaluating the effect of the new standard on its consolidated financial statements and related disclosures.

Other recent accounting pronouncements issued by the FASB during fiscal 2015 and through the period ended June 30, 2016 are not believed by management to have a material impact on the Company's present or historical consolidated financial statements.
