Note 1.    Nature of Business

Customers in the United States represented 73% and 82% of our consolidated revenues for the three months ended March 31, 2019 and 2018, respectively, with the balance in Canada, the United Kingdom, China, Singapore, Netherlands, and other countries around the world.

Unaudited Interim Financial Information

The accompanying unaudited interim condensed consolidated financial statements and information have been prepared in accordance with accounting principles generally accepted in the United States and in accordance with the SEC's regulations for interim financial information and with the instructions for Form 10-Q. Accordingly, they do not include all of the information and disclosures required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, these financial statements contain all normal and recurring adjustments considered necessary to present fairly the Company's financial position, results of operations, comprehensive income, cash flows, and stockholders’ equity for the periods presented. The results for the three months ended March 31, 2019 are not necessarily indicative of the results to be expected for the full year.

These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2018 filed with the Securities and Exchange Commission on February 27, 2019.

Use of Estimates

Our condensed consolidated financial statements and notes thereof are prepared in conformity with accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and the accompanying notes. Actual results could differ materially from these estimates.

Reclassifications

Reclassifications have been made to our condensed consolidated financial statements for the prior year periods to conform to classifications used in the current year periods. The reclassifications did not affect results of operations or net assets.

Note 2.    Summary of Significant Accounting Policies

This footnote should be read in conjunction with the complete description of our significant accounting policies under Note 2, Summary of Significant Accounting Policies to our Annual Report on Form 10-K for the year ended December 31, 2018.

Cost of Revenues

Cost of revenues excludes depreciation and amortization expense of $9,418 and $6,434 for the three months ended March 31, 2019 and 2018, respectively. In addition, costs of goods sold included in cost of revenues during the three months ended March 31, 2019 and 2018 were $5,628 and $6,297, respectively.

Sales and Marketing Expenses

We incurred advertising costs which are included in sales and marketing of $17,750 and $14,521 for the three months ended March 31, 2019 and 2018, respectively.

Leases

At inception of a contract, the Company determines whether the contract is or contains a lease. Further, the Company determines if the arrangement qualifies as an operating lease or a finance lease. Operating leases are included in operating lease right-of-use assets, operating lease liabilities - current portion and operating lease liabilities on the Company's consolidated balance sheet. The Company does not have any finance leases as of March 31, 2019 and January 1, 2019.

A right-of-use asset represents the Company's right to use the underlying asset for the lease term and the lease liabilities represent our obligation to make lease payments under the leasing arrangement. We recognize an operating lease right-of-use asset and operating lease liability at the arrangement's commencement date based upon the present value of the lease payments over the lease term. We utilize our incremental borrowing rate based on the information available at the commencement date in order to determine the present value of lease payments or the implicit rate when readily determinable. The Company's lease arrangements may include options to extend or terminate the lease arrangement. Such options are included in the determination of lease term when it is reasonably certain that the Company will exercise that option. The Company recognizes lease expense for lease payments on a straight-line basis over the term of the lease. The Company has made an accounting policy election for leases that at the commencement date have terms of twelve months or less to not recognize an operating lease right-of-use assets or operating lease liabilities on its balance sheet. Instead, the Company recognizes lease payments as an expense in accordance with the lease terms.

Fair Value of Financial Instruments

The Company records certain of its financial assets at fair value on a recurring basis as described below. Certain of the Company's other financial instruments, which include cash and cash equivalents, accounts receivable and accounts payable, approximate fair value because of their short-term maturities. We believe the fair value of our debt at March 31, 2019 and December 31, 2018 was approximately the same as its carrying amount as market conditions, including available interest rates, credit spread relative to our credit rating, and illiquidity, remain relatively unchanged from the issuance date of our debt obligations for a similar debt instrument and are classified as Level 3 within the fair value hierarchy.

VONAGE HOLDINGS CORP.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(In thousands, except per share amounts)

(Unaudited)

We account for financial assets using a framework that establishes a hierarchy that ranks the quality and reliability of the inputs, or assumptions, we use in the determination of fair value, and we classify financial assets and liabilities carried at fair value in one of the following three categories:

•Level 1 - quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets and liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

•Level 2 - observable prices that are based on inputs not quoted on active markets but corroborated by market data; and

•Level 3 - unobservable inputs when there is little or no market data available, thereby requiring an entity to develop its own assumptions. The fair value hierarchy gives the lowest priority to Level 3 inputs.

The following table presents the assets that are measured and recognized at fair value on a recurring basis classified under the appropriate level of the fair value hierarchy as of March 31, 2019 and December 31, 2018:

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The ASU simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. This ASU is effective for an annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019 on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of ASU 2017-04 is not expected to have a material impact on our condensed consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments which requires the use of a new current expected credit loss ("CECL") model in estimating allowances for doubtful accounts with respect to accounts receivable, straight-line receivable and notes receivable. Receivables from revenue transactions, or trade receivables, are recognized when the corresponding revenue is recognized under ASC Topic 606, Revenue from Contracts with Customers. The CECL model requires that the Company estimate its lifetime expected credit loss with respect to these receivables and record allowances that when deducted from the balance of the receivables, represent the estimated net amounts expected to be collected. Given the generally short term nature of trade receivables, we do not expect to apply a discounted cash flow methodology. However, the Company will consider whether historical loss rates are consistent with expectations of forward-looking estimates for our trade receivables. In November 2018, the FASB issued ASU 2018-19 to clarify that operating lease receivables recorded by lessors are explicitly excluded from the scope of Topic 326. This ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. While we are still evaluating the impact of this guidance on our consolidated financial statements, we do not currently believe it will have a material impact upon adoption.

(Unaudited)

The following standard was adopted by the Company during the current period:

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)" which replaces the guidance on accounting for leases in Topic 840. The new guidance increases transparency and comparability among organizations by requiring lessees to recognize assets and liabilities on the balance sheet for most leases and disclose key information about leasing arrangements.

The Company adopted the new standard on January 1, 2019 using a modified retrospective transition approach, which involves applying the new standard to all leases existing at the date of the initial application with any cumulative impact of the adoption recorded to retained earnings. In addition, we elected the package of practical expedients permitted under the transition guidance which allows the Company to carry forward the historical lease classification. The adoption of Topic 842 has had a significant effect on our balance sheet, mostly related to (1) the recognition of new right-of-use assets and new lease liabilities on our balance sheet for our existing operating leases (most notably leases of office space and co-location space); and (2) the derecognition of existing assets (most notably prepaid rent), and existing liabilities (most notably deferred rent) related to such leases. It will not materially affect our earnings or cash flows. We recorded the following transactions on January 1, 2019:

• Recognized currently unrecognized right-of-use assets of $57.3 million net of deferred rent and lease incentives which were previously included in other liabilities.

• Recognized currently unrecognized lease liabilities of $64.5 million (based on the present value of the remaining minimum rental payments for existing operating leases).

• Recognized an adjustment to retained earnings of $458 thousand related to release of deferred tax assets.

Contract Assets and Liabilities

The following table provides information about receivables and contract liabilities from contracts with customers:

	March 31, 2019		December 31, 2018
Receivables (1)	$	73,375	$	75,342
Contract liabilities (2)	53,628		53,447

(1) Amounts included in accounts receivables on our condensed consolidated balance sheet.

(2) Amounts included in deferred revenues and other liabilities on our condensed consolidated balance sheet.

Our deferred revenue represents the advance consideration received from customers for subscription services and is predominantly recognized over the following performance period which is generally a month as transfer of control occurs. During the three months ended March 31, 2019 and 2018, the Company recognized revenue of $100,434 and $119,371, respectively, related to its contract liabilities. We expect to recognize $53,628 into revenue over the next twelve months related to our deferred revenue as of March 31, 2019.

Contract Acquisition Costs

We have various commission programs for which eligible employees and third parties may earn commission on sales of services and products to customers. We expect that these commission fees are recoverable and, therefore, we have capitalized $54,565 and $49,636 as contract costs, net of accumulated amortization, as of March 31, 2019 and December 31, 2018, respectively, included within deferred customer acquisitions costs, current portion and deferred customer acquisition costs on our condensed consolidated balance sheet. Capitalized commission fees are amortized to sales and marketing expense over estimated customer life, which is 7 years for Business customers. During the three months ended March 31, 2019 and 2018, the amounts amortized to sales and marketing were $2,530 and $2,159, respectively, and there were no impairment losses recognized in relation to the costs capitalized. In addition, the Company expenses sales commissions for commission plans related to customer arrangements deemed less than a year and for residuals and renewals.

Note 4. Acquisitions and Dispositions

Acquisition of NewVoiceMedia

On October 31, 2018, the Company acquired 100% of the issued and outstanding shares of NewVoiceMedia Limited (“NewVoiceMedia”), a cloud Contact Center-as-a-Service (CCaaS) provider, for a purchase price of $350,179 paid in cash.

The acquisition was recorded as a business combination under ASC 805, with identifiable assets acquired and liabilities assumed provisionally recorded at their estimated fair value on the acquisition date. The initial accounting for the business combination is not complete because the evaluations necessary to assess the fair values of certain net assets acquired inclusive of deferred tax liabilities is still in process. The allocation of the purchase price may be modified up to one year from the date of the acquisition as more information is obtained about the fair value of assets acquired and liabilities assumed. Under the terms of the offer, NewVoiceMedia shareholders received cash in the amount of approximately $341 million as well as transactions costs incurred by NewVoiceMedia which were paid by the Company of approximately $9 million on the date of the acquisition.

Note 7.    Long-Term Note and Revolving Credit Facility

This footnote should be read in conjunction with the complete description of our financing arrangements under Note 7, Long-Term Debt and Revolving Credit Facility to our Annual Report on Form 10-K for the year ended December 31, 2018.

A schedule of long-term note and revolving credit facility at March 31, 2019 and December 31, 2018 is as follows:

	March 31, 2019		December 31, 2018

Revolving credit facility - due 2023	466,500		425,000
Total Long-term note and revolving credit facility	$	548,265	$	509,228

2018 Term Note and Revolving Credit Facility

On July 31, 2018, the Company replaced its 2016 Credit Facility previously consisting of a $125 million term loan and a $325 million revolving credit facility with the 2018 Credit Facility consisting of a $100 million senior secured term loan and a $500 million revolving credit facility. The co-borrowers under the 2018 Credit Facility are the Company and Vonage America Inc., the Company’s wholly owned subsidiary. Obligations under the 2018 Credit Facility are guaranteed, fully and unconditionally, by the Company’s other United States subsidiaries and are secured by substantially all of the assets of each borrower and each guarantor.

The Company used $232,000 of the proceeds available under our 2018 Credit Facility plus cash on hand to retire all of the debt outstanding under our 2016 Credit Facility and to cover transaction fees and expenses. Total transaction fees and expense incurred were $3,376, of which $474 was allocated to the term note and $2,813 was allocated to the revolving credit facility which will be amortized over the term of 2018 Credit Facility. The remaining $89 of transaction fees and expenses were expensed during the year ended December 31, 2018. The Company recognized a loss on extinguishment of debt of $14 which primarily consisted of the write off of previously deferred financing costs partially offset by the realization of a portion of gains associated with the interest rate swaps included in accumulated other comprehensive income during the year ended December 31, 2018. Remaining proceeds available from the undrawn revolving credit facility under our 2018 Credit Facility will be used for general corporate purposes and to fund potential additional acquisitions.

During the three months ended March 31, 2019, we made mandatory repayments of $2.5 million under the 2018 term note and borrowed $41.5 million under the revolving credit facility. In addition, the effective interest rate was 5.25% as of March 31, 2019.

As of March 31, 2019, we were in compliance with all covenants, including financial covenants, for the 2018 Credit Facility.

2016 Financing

During the three months ended March 31, 2018, we made mandatory repayments of $4.7 million under the term note and made discretionary repayments of $5.0 million under the revolving credit facility and borrowed $10.0 million under the revolving credit facility.

Interest Rate Swaps

On July 14, 2017, we executed on three interest rate swap agreements in order to hedge the variability of expected future cash interest payments related to the 2016 Credit Facility. The swaps have an aggregate notional amount of $150 million and were effective from July 31, 2017 through June 3, 2020 concurrent with the term of the 2016 Credit Facility. Under the swaps our interest rate is fixed at 4.7%. The interest rate swaps are accounted for as cash flow hedges in accordance with ASC 815, Derivatives and Hedging.

Note 10.    Commitments and Contingencies

Litigation

From time to time we are subject to legal proceedings, claims, investigations, and proceedings in the ordinary course of business, including claims of alleged infringement of third-party patents and other intellectual property rights, commercial, employment, and other matters. From time to time, we receive letters or other communications from third parties inviting us to obtain patent licenses that might be relevant to our business or alleging that our services infringe upon third party patents or other intellectual property. In accordance with generally accepted accounting principles, we make a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss or range of loss can be reasonably estimated. These provisions, if any, are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. Litigation is inherently unpredictable. We believe that we have valid defenses with respect to the legal matters pending against us and are vigorously defending these matters. Given the uncertainty surrounding litigation and our inability to assess the likelihood of a favorable or unfavorable outcome in such matters and our inability to reasonably estimate the amount of loss or range of loss, it is possible that the resolution of one or more of these matters could have a material adverse effect on our condensed consolidated financial position, cash flows or results of operations.

Regulation

Telephony services are subject to a broad spectrum of state, federal and foreign regulations. Because of the uncertainty over whether Voice over Internet Protocol (“VoIP”) should be treated as a telecommunications or information service, we have been involved in a substantial amount of state and federal regulatory activity. Implementation and interpretation of the existing laws and regulations is ongoing and is subject to litigation by various federal and state agencies and courts. Due to the uncertainty over the regulatory classification of VoIP service, there can be no assurance that we will not be subject to new regulations or existing regulations under new interpretations, and that such change would not introduce material additional costs to our business. The Company continues to monitor federal regulations relating to net neutrality, rural call completion issues, number slamming, 911 access, access to telecommunication equipment and services by persons with disabilities, caller ID services, number portability, unwanted calls to reassigned numbers, and robocalling. As we continue to expand globally, these types of regulations are likely to be similarly enacted and enforced by the local regulatory authorities.    

State and Municipal Taxes

In accordance with generally accepted accounting principles, we make a provision for a liability for taxes when it is both probable that a liability has been incurred and the amount of the liability or range of liability can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. For a period of time, we did not collect or remit state or municipal taxes (such as sales, excise, utility, use, and ad valorem taxes), fees or surcharges (“Taxes”) on the charges to our customers for our services, except that we historically complied with the New Jersey sales tax. We have received inquiries or demands from a number of state and municipal taxing and 911 agencies seeking payment of Taxes that are applied to or collected from customers of providers of traditional public switched telephone network services. Although we have consistently maintained that these Taxes do not apply to our service for a variety of reasons depending on the statute or rule that establishes such obligations, we are now collecting and remitting sales taxes in certain of those states including a number of states that have changed their statutes to expressly include VoIP. In addition, many states address how VoIP providers should contribute to support public safety agencies, and in those states we remit fees to the appropriate state agencies. We could also be contacted by state or municipal taxing and 911 agencies regarding Taxes that do explicitly apply to VoIP and these agencies could seek retroactive payment of Taxes. As such, we have established reserves of $3,380 and $3,302 as of March 31, 2019 and December 31, 2018, respectively, as our best estimate of the potential tax exposure for any retroactive assessment.

Note 11.  Industry Segment and Geographic Information

ASC 280 "Segment Reporting" establishes reporting standards for an enterprise's business segments and related disclosures about its products, services, geographic areas and major customers. Under ASC 280, the method for determining what information to report is based upon the way management organizes the operating segments within the Company for making operating decisions and assessing financial performance. Our chief operating decision-maker reviews revenue and gross margin information for each of our reportable segments, but does not review operating expenses on a segment by segment basis. In addition, with the exception of goodwill and intangible assets, we do not identify or allocate our assets by the reportable segments.

Business

For our Business customers, we provide innovative, cloud-based UCaaS solutions, comprised of integrated voice, text, video, data, collaboration, and mobile applications over our flexible, scalable SIP based VoIP network. Through Nexmo, the Vonage API Platform, we also offer CPaaS solutions designed to enhance the way businesses communicate with their customers embedding communications into apps, websites and business processes.

Overview and Strategy

At Vonage, our strategy is to redefine business communications. True to our roots as a technology disruptor, we are embracing technology to transform how businesses communicate to create better business outcomes. Our cloud communications platform enables businesses of all sizes to collaborate more productively and engage their customers more efficiently across any device.

We believe we have a unique set of capabilities and solutions to deliver on the full business communications value chain to help enterprises use cloud communications to improve how business gets done. Vonage offers a unique combination of unified communications, programmable communications and contact center to transform the way businesses communicate all on one platform. We build integrated solutions through programmable communications, complementing and adding more value and customizations to unified communications as a service and cloud contact center solutions.

The OneVonage microservices platform creates specific tools customers need to address the unique communication challenges their businesses face. All of our cloud communications solutions are designed to provide employees with the tools they need to connect, collaborate and be more productive internally while enabling them to engage with customers externally for a better customer experience and more meaningful relationships.

We also provide a robust set of feature-rich residential communication solutions that allow consumers to connect their home phones and mobile phones on one number and we offer attractive international long distance rates that help create a loyal base of satisfied customers.

Our business is organized under two reportable segments, Business and Consumer. Additional discussion of our reportable segments is included in Note 11, Industry Segment and Geographical Information to the Consolidated Financial Statements.

27

Segment Overview

 We are a leading provider of cloud communications services for businesses and consumers. Our business services transform the way people work and businesses operate through a portfolio of communications solutions that enable internal collaboration among employees, while also keeping companies closely connected with their customers, across any mode of communication, on any cloud-connected device. Vonage customers can choose among or combine two separate service delivery options to suit their specific cloud communication needs. They can buy Vonage Business as a subscription through our Applications Group offering our UCaaS and CCaaS and they can buy our API Platform which consists of a broad set of programmable communication APIs. We also provide a robust suite of feature-rich residential communication solutions.

Business

For our Business customers, we provide innovative, cloud-based Unified Communications as a Service, or UCaaS, solutions, comprised of integrated voice, text, video, data, collaboration, and mobile applications over our flexible, scalable Session Initiation Protocol based Voice over Internet Protocol, or VoIP, network. We also offer CPaaS solutions designed to enhance the way businesses communicate with their customers by embedding communications into apps, websites and business processes. In August 2018, the Company completed the acquisition of TokBox which added video functionality to the CPaaS suite of services available to its customers. In combination, our products and services permit our business customers to communicate with their customers and employees through any cloud-connected device, in any place, at any time without the often costly investment required with on-site equipment. We have a robust set of product families tailored to serve the full range of the business value chain, from the SMB market, through mid-market and enterprise markets. We provide customers with multiple deployment options, designed to provide the reliability and quality of service they demand. We provide customers the ability to integrate our cloud communications platform with many cloud-based productivity and CRM solutions, including Google’s G Suite, Zendesk, Salesforce’s Sales Cloud, Oracle, and Clio. With our ability to integrate these cloud-based, workplace tools, Vonage integrates the entire business communications value chain - from employee communications that maximize productivity to the direct engagement with customers that CPaaS provides. When combined with our MPLS network, as well as voice services over customers' broadband networks via our SmartWan solution, we create a differentiated offering. On October 31, 2018, the Company completed the acquisition of NewVoiceMedia, a leading provider of Contact Center as a Service, or CCaaS, solutions allowing the Company to compliment its existing suite of cloud communications services available to its customers.

Consumer

For our Consumer customers, we enable users to access and utilize our services and features, via their existing internet connections, including over 3G/4G, LTE, Cable, or DSL broadband networks. This technology enables us to offer our Consumer customers attractively priced voice and messaging services and other features around the world on a variety of devices. Our Consumer strategy is focused on the continued penetration of our core North American markets, where we will continue to provide value in international long distance and target under-served segments.

Services Outside of the United States

We currently have operations delivering our suite of communication solutions in the United States, United Kingdom, Hong Kong, Singapore, and Canada and believe that our platforms enables us to cost effectively deliver voice and messaging services to other locations throughout the world.

Trends in Our Industry

A number of trends in our industry have a significant effect on our results of operations and are important to an understanding of our financial statements.

Competitive landscape. We face intense competition from traditional telephone companies, wireless companies, cable companies, and alternative communication providers. Most traditional wireline and wireless telephone service providers and cable companies are substantially larger and better capitalized than we are and have the advantage of a large existing customer base. In addition, because our competitors provide other services, they often choose to offer VoIP services or other voice services as part of a bundle that includes other products, such as video, high speed Internet access, and wireless telephone service, which we do not offer. We also compete against alternative communication providers. Some of these service providers have chosen to sacrifice telephony revenue in order to gain market share and have offered their services at low prices or for free. As we continue to introduce applications that integrate different forms of voice and messaging services over multiple devices, we are facing competition from emerging competitors focused on similar integration, as well as from alternative voice communication providers. We also are subject to the risk of future disruptive technologies. In connection with our emphasis on the international long distance market in the United States, we face competition from low-cost international calling cards and VoIP providers in addition to traditional telephone companies, cable companies, and wireless companies, each of which may implement promotional pricing targeting international long distance callers.

28

Regulation. Our business has developed in a lightly regulated environment. See the discussion under "Regulation" in Note 10 to our financial statements for a discussion of regulatory issues that impact us.

Key Operating Data

The table below includes key operating data that our management uses to measure the growth and operating performance of the Business segment:

Business	Three Months Ended
	March 31,
	2019			2018
Service revenue per customer	$	408		$	328
Business revenue churn	1.2		%	1.2		%

Service Revenue per Customer. Service revenues per customer for a particular period is calculated by dividing the average monthly service revenues for the period by the average number of customers over the number of months in the period. The average number of customers is the number of customers on the first day of the period, plus the number of customers on the last day of the period, divided by two. Service revenues excludes revenues from trading and auction customers. Service revenue per customer increased from $328 for the three months ended March 31, 2018 to $408 for the three months ended March 31, 2019 primarily driven by the Company's successful efforts to attract larger business customers and to expand services provided to our existing business customers along with the acquisition of NewVoiceMedia and TokBox during the second half of 2018.

Business Revenue Churn. Business revenue churn is calculated by dividing the revenue from customers or customer locations that have been confirmed to be foregone during a period by the simple average of the total revenue from all customers in that period. Revenue for purposes of determining Business revenue churn is service revenue excluding revenue from our trading and auction customers, and usage in excess of a customer’s contracted service plan, regulatory fees charged to customers, and credits. The simple average of total revenue from all customers during the period is the total revenue as defined herein on the first day of the period, plus the total revenue as defined herein on the last day of the period, divided by two. Terminations, as used in the calculation of churn statistics, do not include customers terminated during the period if termination occurred within the first month after activation. Other companies may calculate business revenue churn differently, and their business revenue churn data may not be directly comparable to ours. Business revenue churn was flat at 1.2% for the three months ended March 31, 2018 and 2019.  Our revenue churn may fluctuate over time due to economic conditions, seasonality in certain customer's operations, loss of customers who are acquired, and competitive pressures including promotional pricing. We are continuing to invest in our overall quality of service which includes customer care headcount and systems, billing systems, on-boarding processes and self-service options to ensure we scale our processes to our growth and continue to improve the overall customer experience.

The table below includes key operating data that our management uses to measure the growth and operating performance of the Consumer segment:

Consumer	Three Months Ended
	March 31,
	2019			2018
Average monthly revenues per subscriber line	$	26.43		$	26.58
Subscriber lines (at period end)	1,232,857			1,439,669
Customer churn	1.9		%	1.9		%

Average Monthly Revenues per Subscriber Line. Average monthly revenues per subscriber line for a particular period is calculated by dividing our revenues for that period by the simple average number of subscriber lines for the period, and dividing the result by the number of months in the period. The simple average number of subscriber lines for the period is the number of subscriber lines on the first day of the period, plus the number of subscriber lines on the last day of the period, divided by two. Our average monthly revenues per subscriber line decreased from $26.58 for the three months ended March 31, 2018 to $26.43 for the three months ended March 31, 2019 due primarily to the Company's ability to retain its more tenured customers.

29

Subscriber Lines. Our subscriber lines include, as of a particular date, all paid subscriber lines from which a customer can make an outbound telephone call on that date. Our subscriber lines include fax lines, including fax lines bundled with subscriber lines in our small office home office calling plans and soft phones, but do not include our virtual phone numbers and toll free numbers, which only allow inbound telephone calls to customers. Subscriber lines decreased from 1,439,669 as of March 31, 2018 to 1,232,857 as of March 31, 2019, reflecting planned actions to enhance the profitability of the assisted sales channel by eliminating lower performing locations and restructuring the pricing offers, and to shift investment to our business market.

Customer Churn. Customer churn is calculated by dividing the number of customers that have terminated during a period by the simple average of number of customers in a given period. The simple average number of customers during the period is the number of customers on the first day of the period, plus the number of customers on the last day of the period, divided by two. Terminations, as used in the calculation of churn statistics, do not include customers terminated during the period if termination occurred within the first month after activation. Other companies may calculate customer churn differently, and their customer churn data may not be directly comparable to ours. Customer churn remained at 1.9% for the three months ended March 31, 2018 and 2019. We monitor customer churn on a daily basis and use it as an indicator of the level of customer satisfaction. Customers who have been with us for a year or more tend to have a lower churn rate than customers who have not. In addition, our customers who are international callers generally churn at a lower rate than customers who are domestic callers. Our customer churn will fluctuate over time due to economic conditions, competitive pressures including promotional pricing targeting international long distance callers, marketplace perception of our services, and our ability to provide high quality customer care and network quality and add future innovative products and services. See the discussion below for detail regarding churn impacting our business customers.

REVENUE

Revenues consist of services revenue and customer equipment and shipping fee revenue. Substantially all of our revenues are services revenue. For Consumer customers in the United States, we offer domestic and international rate plans, including a variety of residential plans and mobile plans. For our Business customers, we offer SMB, mid-market, and enterprise customers several service plans with different pricing structures and contractual requirements ranging in duration from month-to-month to three years. In addition, we provide managed equipment to Business customers for which the customers pay a monthly fee. Customers also have the opportunity to purchase premium features for additional fees. In addition, we derive revenue from usage-based fees earned from customers using our cloud-based software products. These usage-based software products include our messaging, voice, Verify and chat APIs. Usage-based fees include number of text messages sent or received using our messaging APIs, minutes of call duration activity for our voice APIs, and number of converted authentications for our Verify API. Services revenue is offset by the cost of certain customer acquisition activities, such as rebates and promotions. In addition, in certain instances, we charge disconnect fees which are recognized as revenue at the time the disconnect fees are collected from our customer.

In the United States, we charge regulatory, compliance, E-911, and intellectual property-related recovery fees on a monthly basis to defray costs, and to cover taxes that we are charged by the suppliers of telecommunications services. In addition, we recognize revenue on a gross basis for contributions to the Federal Universal Service Fund, or USF, and related fees. All other taxes are recorded on a net basis.

Revenues are generated from sales of customer equipment directly to customers for replacement devices, or for upgrading their device at the time of customer sign-up for which we charge an additional fee. In addition, customer equipment and shipping revenues include revenues from the sale of VoIP telephones in order to access our small and medium business services. Customer equipment and shipping revenues also include the fees that customers are charged for shipping their customer equipment to them.

OPERATING EXPENSES

Operating expenses consist of cost of revenues, sales and marketing expense, engineering and development expense, general and administrative expense, and depreciation and amortization.

Management's Discussion of the Results of Operations for the Three Months Ended March 31, 2019 and 2018

The Company reported loss before income taxes of $10,584 for the three months ended March 31, 2019 and income before income taxes of $14,254 for the three months ended March 31, 2018, respectively. The decrease was primarily driven by higher other operating expenses of $36,384 as a result of the acquisitions of NewVoiceMedia in October 2018 and TokBox in August 2018 driven by increases in salary costs due to higher headcount, increases in sales and marketing expenses, and increases in depreciation and amortization expenses due to additional assets acquired. In addition, there were increases in engineering and development expenses in connection with the Company's continued transformation focused on innovation.

The Company reported net loss of $534 and net income of $24,524 for the three months ended March 31, 2019 and 2018, respectively. The decrease in net (loss)/income for the three months ended March 31, 2019 compared to the three months ended March 31, 2018 is mainly due to the aforementioned decrease in (loss)/income before income taxes offset by the decrease in income tax benefit of $220.

31

We calculate gross margin as total revenues less cost of revenues, which primarily consists of fees that we pay to third parties on an ongoing basis in order to provide our services and costs incurred when a customer first subscribes to our service. The following table presents consolidated revenues, cost of revenues and the composition of gross margin for the three months ended March 31, 2019 and 2018:

(in thousands, except percentages)	Three Months Ended
	March 31,
	2019		2018		Dollar Change		Percent Change
Total revenues	$	279,541	$	253,573	$	25,968	10	%
Cost of revenues (1)	113,411		103,567		9,844		10	%
Gross margin	$	166,130	$	150,006	$	16,124	11	%

(1) Excludes depreciation and amortization of $9,418 and $6,434 for the three months ended March 31, 2019 and 2018, respectively.

Total revenues and cost of revenues were impacted by the following trends and uncertainties:

Three Months Ended March 31, 2019 compared to Three Months Ended March 31, 2018

Total revenues increased 10% for the three months ended March 31, 2019 as compared to the prior year period. The increase is primarily due to the acquisition of NewVoiceMedia and TokBox in the second half of 2018 along with business customer growth driving an increase in revenues of $42,929, offset by declining consumer revenues of $16,961 in connection with the continued decline of subscriber lines. The Company continues to expect that the Consumer portion of the Company's overall business will become less significant as the Company reallocates resources to increase market share in its Business communications platforms.

Cost of revenues increased 10% for the three months ended March 31, 2019 as compared to the prior year period driven by increased costs incurred in servicing our Business customers of $16,967 due to the increase in customers and prior year acquisitions. This was partially offset by a decrease in costs in Consumer of $7,123 as subscriber lines continues to decline resulting in lower international and long-distance termination costs.

Three Months Ended March 31, 2019 compared to Three Months Ended March 31, 2018

The following table describes the increase in business gross margin for the three months ended March 31, 2019 as compared to the three months ended March 31, 2018:

	(in thousands)
Service gross margin excluding the impact of the acquisitions increased 19% primarily due to overall growth in our Business customer base of 11% as compared to the prior year quarter	$	11,767
Service gross margin also increased due to acquisitions of TokBox on August 1, 2018 and NewVoiceMedia on October 31, 2018, respectively	14,404
Access and product gross margin decreased due to higher costs providing access services to Business customers during the current quarter	(214		)
USF gross margin increased mainly due to payment during the first quarter of 2018 for USF fees not collected in 2017	5
Increase in segment gross margin	$	25,962

33

Business service gross margin percentage increased to 56.2% for the three months ended March 31, 2019 from 54.4% for the three months ended March 31, 2018. The increase in business service gross margin percentage is a result of the acquisition of NewVoiceMedia along with the sale of a greater proportion of higher margin services across our Business segment during the quarter ended March 31, 2019 as compared to the same period in the prior quarter. Our gross margin percentage may continue to be impacted by changes in the mix of service offerings provided to our customers across our Business segment.

Three Months Ended March 31, 2019 compared to Three Months Ended March 31, 2018

The following table describes the decrease in consumer gross margin for the three months ended March 31, 2019 as compared to the three months ended March 31, 2018:

	(in thousands)
Service gross margin decreased primarily due to a decrease in subscriber lines of 14% resulting in lower gross margin of $11,303 as we have reallocated resources focused on attracting Business customers. This was offset by a slight increase in average revenue per customer and lower overall costs incurred by the Consumer segment resulting in increased gross margin of $665	$	(10,638	)
Access and product gross margin increased 45% primarily due lower equipment costs associated with sales to customers during the current quarter	774
USF gross margin increased mainly due to payment during the first quarter of 2018 for USF fees not collected in 2017	26
Decrease in segment gross margin	$	(9,838	)

Consumer service gross margin percentage increased to 89.6% for the three months ended March 31, 2019 from 86.6% for the three months ended March 31, 2018 due to lower international and domestic termination rates and the allocation of certain shared network costs to Business as that revenue becomes a greater proportion of the whole. The increase in Consumer service margin percentage is also driven by overall lower costs attributed to consumer services as the Company shifts resources towards attracting more profitable Business customers.

Other Operating Expenses 

The following table presents our other operating costs during the three months ended March 31, 2019 and 2018, respectively:

Three Months Ended March 31, 2019 compared to Three Months Ended March 31, 2018

Total other operating expenses increased by $36,384 as compared to the three months ended March 31, 2018 due to the following:

• Sales and marketing expense increased by $18,387, primarily due to additional costs from TokBox and NewVoiceMedia which were acquired in August 2018 and October 2018, respectively. Additionally, sales and marketing costs were impacted by increased spending in the current year related to media marketing initiatives and the attendance at certain conferences which were not attended in the previous year.

• Engineering and development expense increased by $5,706, in connection with the Company's continued transformation focus on innovation especially in regards to developing further functionality related to its proprietary platform in order to support customers through the mid-market and enterprise sector.

• General and administrative expense increased by $7,877, primarily due to higher personnel costs driven by the increase in headcount following the acquisition of TokBox and NewVoiceMedia.

• Depreciation and amortization expense increased by $4,414 primarily due to the amortization of acquired intangible assets related to TokBox and NewVoiceMedia.

Interest expense. The increase in interest expense of $4,415, or 140%, was mainly due to higher principal balances on our 2018 Credit Facility that we entered into in July 2018 along with rising rates during three months ended March 31, 2019.

We recognize income tax equal to pre-tax income multiplied by our effective income tax rate. In addition, adjustments are recorded for discrete period items and changes to our state effective tax rate which can cause the rate to fluctuate from quarter to quarter.

During the three months ended March 31, 2019, the Company has recorded a benefit related to excess share-based stock compensation driving the majority of the income tax benefit recognized.

During the three months ended March 31, 2018 , we recognized discrete period tax benefits of $15,307 which was recognized related to excess tax benefits on equity compensation recognized in the first quarter of 2018 offset by a permanent adjustment of $6,702 related to GILTI tax rules under the TCJA which was enacted in December 2017.

Liquidity and Capital Resources

Overview

For the three months ended March 31, 2019, we had lower net cash from operations compared to the prior year quarter mainly due to lower net income. We expect to continue to balance efforts to grow our revenue while consistently achieving operating profitability. To grow our revenue, we continue to make investments in growth initiatives, marketing, application development, network quality and expansion, and customer care. Although we believe we will achieve consistent profitability in the future, we ultimately may not be successful and we may not achieve consistent profitability. We believe that cash flow from operations and cash on hand will fund our operations for at least the next twelve months.

The following table sets forth a summary of our cash flows for the periods indicated:

	Three Months Ended
	March 31,
(in thousands)	2019			2018			Dollar Change
Net cash provided by operating activities	$	2,750		$	23,468		$	(20,718	)
Net cash used in investing activities	(10,774		)	(6,397		)	(4,377		)
Net cash provided by (used in) financing activities	20,786			(25,062		)	45,848
Effect of exchange rate changes on cash and cash equivalents	260			35			225

Operating Activities

Cash provided by operating activities decreased to $2,750 for the three months ended March 31, 2019 from $23,468 for the three months ended March 31, 2018, primarily due to a decrease in earnings as compared to the prior period as a result of acquisitions and a decrease in accounts payable of $11,446 due to the timing of payments, offset by an increase in amortization of intangible assets of $5,351 driven by acquired intangible assets associated with NewVoiceMedia in the second half of 2018.

Changes in working capital include changes in accounts receivable, inventory, prepaid and other assets, accounts payable, accrued and other liabilities, and deferred revenue and costs. Cash used for working capital requirements increased by $1,341 during the three months ended March 31, 2019 compared to the prior year period primarily due to the timing of payments.

Investing Activities

Cash used in investing activities for the three months ended March 31, 2019 of $10,774 was mainly attributable to the purchase of capital expenditures of $5,277 and development of software assets of $5,497.

Cash used in investing activities for the three months ended March 31, 2018 of $6,397 was mainly attributable to the purchase of capital expenditures of $3,250 and development of software assets of $3,147.

Financing Activities

Cash provided by financing activities for the three months ended March 31, 2019 of $20,786 was primarily attributable to $41,500 in proceeds received from draws on the 2018 credit facility and $480 in proceeds received from the exercise of stock options, offset by $2,500 of repayments under the 2018 credit facility in the first quarter of 2019 and $18,566 in employee taxes paid on withholding shares.

Cash used in financing activities for the three months ended March 31, 2018 of $25,062 was primarily attributable to $4,687 in 2016 term note principal payments, $5,000 in 2016 revolving credit facility principal payments, $59 in capital lease payments, and $27,487 in employee taxes paid on withholding shares, offset by $2,171 in proceeds received from the exercise of stock options and $10,000 in proceeds received from issuance of notes payable.

Sources of Liquidity

The principal sources of liquidity are derived from available borrowings under our existing financing arrangements, existing cash on hand, and cash flows from operations. As described in Note 7, Long-Term Debt and Revolving Credit Facility, to the Consolidated Financial Statements, the Company's financing arrangements consist of the 2018 Credit Facility comprised of a $100,000 term note and a $500,000 revolving credit facility.

37

Available Borrowings Under the 2018 Credit Facility

We maintain significant availability under our lines of credit to meet our short-term liquidity requirements. As of March 31, 2019, amounts available under the 2018 Credit Facility totaled $33.3 million.

State and Local Sales Taxes

We have contingent liabilities for state and local sales taxes. As of March 31, 2019, we had a reserve of $3,380. If our ultimate liability exceeds this amount, it could affect our liquidity unfavorably. However, we do not believe it will significantly impair our liquidity.

Capital Expenditures

Our capital expenditures for the three months ended March 31, 2019 were $10,774, of which $5,497 was for software acquisition and development. The majority of these expenditures are comprised of investments in information technology and systems infrastructure, including an electronic data warehouse, online customer service, and customer management platforms. For 2019, we believe our capital and software expenditures will be approximately $40,000.

Off-Balance Sheet Arrangements

Obligations under Certain Guarantee Contracts

We enter guarantee arrangements in the normal course of business to facilitate transactions with third parties. These arrangements include financial and performance guarantees, stand-by letters of credit, debt guarantees and indemnifications. As of March 31, 2019 and December 31, 2018 we had stand-by letters of credit totaling $1,520 and $1,516, respectively.

Contractual Obligations and Commitments

Except as set forth below and in Note 10. Commitments and Contingencies included in Part 1, Item 1 of this Form 10-Q, there were no significant changes in our commitments under contractual obligations as disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2018.

Contingencies

There has been and may be in the future substantial litigation in the areas in which we operate regarding alleged infringement of third-party patents and other intellectual property rights, commercial, employment and other matters. We record a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss or range of loss can be reasonably estimated. Such legal proceedings are inherently unpredictable and subject to further uncertainties. Should any of these estimates and assumptions change it is possible that the resolution of the matters described in Note 10, Commitments and Contingencies included in Part 1, Item 1 of this Form 10-Q could have a material adverse effect on our consolidated financial position, cash flows or results of operations.

Critical Accounting Policies

Our consolidated statements and accompanying notes are prepared in accordance with U.S. GAAP. Our significant accounting policies are described in Note 2, Summary of Significant Accounting Policies to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2018. The preparation of financial statements and related disclosures in compliance with GAAP requires management to make estimates and assumptions that affect the reported amount of assets, liabilities, revenues and expenses as well as the disclosure of contingent assets and liabilities. The application of these policies involves judgment regarding future events and these judgments could materially affect the financial statements and disclosures based on varying assumptions, which may be appropriate to use.

We identify our most critical accounting policies as those that are the most pervasive and important to the portrayal of our financial position and results of operations, and those that require the most difficult, subjective or complex judgments by management regarding estimates. Our critical accounting policies include revenue recognition, valuation of goodwill and intangible assets, income taxes and capitalized software. Effective January 1, 2019, the Company adopted ASC Topic 842. Refer to Note 2, Summary of Significant Accounting Policies for changes to our critical accounting policy with respect to recognition of leasing arrangements as a result of the adoption. As of March 31, 2019, our goodwill is attributable to our Business operating segment. We perform our annual test of goodwill on October 1st. Additionally, we will assess our goodwill for impairment between annual tests when specific circumstances dictate.

38

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are exposed to financial market risks, including changes in currency exchange rates and interest rates.

Foreign Exchange Risk

We sell our products and services primarily in the United States, Canada, the European Union, and Asia. A portion of our sales denominated in Euros, the Canadian Dollar, and the British Pound Sterling, which are affected by changes in currency exchange rates. Our financial results could be affected by changes in foreign currency exchange rates, although foreign exchange risks have not been material to our financial position or results of operations to date. Volatility in the British Pound Sterling exchange rate is expected to continue in the short term as the United Kingdom negotiates its exit from the European Union which has been extended through October 31, 2019. If the United Kingdom and the European Union are unable to reach an agreement and the United Kingdom exits the European Union without an agreement in place, it will likely create further short-term uncertainty and currency volatility. In the longer term, any impact from the United Kingdom exiting the European Union on the Company's operations will depend, in part, on the outcome of tariff, trade, regulatory and other negotiations.

Interest Rate and Debt Risk

Our exposure to market risk for changes in interest rates primarily relates to our long-term debt. In order to hedge the variability of expected future cash interest payments related to our credit facilities we have entered into three interest rate swap agreements which were executed on July 14, 2017. The swaps have an aggregate notional amount of $150 million and are effective on July 31, 2017 through June 3, 2020. Under the swaps our interest rate is fixed at 4.7%. The interest rate swaps will be accounted for as cash flow hedges in accordance with ASC 815, Derivatives and Hedging.

As of March 31, 2019, if the interest rate on our variable rate debt changed by 1% on our 2018 term note, our annual debt service payment would change by approximately $700.  As of March 31, 2019, if the interest rate on our variable rate debt changed by 1% on our 2018 revolving credit facility, our annual debt service payment would change by approximately $3,400.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures. Based on the evaluation of our disclosure controls and procedures (as defined in Securities Exchange Act of 1934 Rules 13a-15(e) and 15d-15(e)) required by Securities Exchange Act Rules 13a-15(b) or 15d-15(b), our Chief Executive Officer and our Chief Financial Officer have concluded that as of the end of the period covered by this report, our disclosure controls and procedures were effective.

Changes in Internal Controls. There were no changes in our internal control over financial reporting that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

39

Nature of Business

 Nature of Business

Nature of Operations

Vonage Holdings Corp. (“Vonage”, “Company”, “we”, “our”, “us”) is incorporated as a Delaware corporation. At Vonage, we are redefining business communications. We are embracing technology to transform how businesses communicate to create better business outcomes. Our cloud communications platform enables businesses of all sizes to collaborate more productively and engage their customers more efficiently across any device. All of our cloud communications solutions are designed to allow businesses to be more productive by integrating communications with all their existing business productivity tools and our programmable solutions allow customers to engage with their customers via embedded voice, chat, or messaging to create seamless and contextual communications that makes doing business easier for end customers.

For our business customers, we provide innovative, cloud-based Unified Communications as a Service, or UCaaS, solutions, comprised of integrated voice, text, video, data, collaboration, and mobile applications over our flexible, scalable Session Initiation Protocol, or SIP, based Voice over Internet Protocol, or VoIP, network. We also offer Communications Platform as a Service, or CPaaS, solutions designed to enhance the way businesses communicate with their customers by embedding communications into apps, websites and business processes. With the acquisition of NewVoiceMedia on October 31, 2018, Vonage also provides customers with a robust Contact Center as a Service, or CCaaS, offering, driving intelligent interactions for customers through emerging technologies such as skills-based routing, real-time sentiment analysis and chatbots. NewVoiceMedia's cloud contact center solution, combined with Vonage's offering, provides an end-to-end communications experience for enhanced customer engagement and conversation. In combination, our products and services permit our business customers to communicate with their customers and employees through any cloud-connected device, in any place, at any time without the often costly investment required with on-site equipment.

We also provide a robust suite of feature-rich residential communication solutions that allow consumers to connect their home phones and mobile phones on one number and we offer attractive international long distance rates that help create a loyal base of satisfied customers.

Customers in the United States represented 73% and 82% of our consolidated revenues for the three months ended March 31, 2019 and 2018, respectively, with the balance in Canada, the United Kingdom, China, Singapore, Netherlands, and other countries around the world.

Unaudited Interim Financial Information

The accompanying unaudited interim condensed consolidated financial statements and information have been prepared in accordance with accounting principles generally accepted in the United States and in accordance with the SEC's regulations for interim financial information and with the instructions for Form 10-Q. Accordingly, they do not include all of the information and disclosures required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, these financial statements contain all normal and recurring adjustments considered necessary to present fairly the Company's financial position, results of operations, comprehensive income, cash flows, and stockholders’ equity for the periods presented. The results for the three months ended March 31, 2019 are not necessarily indicative of the results to be expected for the full year.

These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2018 filed with the Securities and Exchange Commission on February 27, 2019.

Use of Estimates

Our condensed consolidated financial statements and notes thereof are prepared in conformity with accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and the accompanying notes. Actual results could differ materially from these estimates.

Reclassifications

Reclassifications have been made to our condensed consolidated financial statements for the prior year periods to conform to classifications used in the current year periods. The reclassifications did not affect results of operations or net assets.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

This footnote should be read in conjunction with the complete description of our significant accounting policies under Note 2, Summary of Significant Accounting Policies to our Annual Report on Form 10-K for the year ended December 31, 2018.

Cost of Revenues

Cost of revenues excludes depreciation and amortization expense of $9,418 and $6,434 for the three months ended March 31, 2019 and 2018, respectively. In addition, costs of goods sold included in cost of revenues during the three months ended March 31, 2019 and 2018 were $5,628 and $6,297, respectively.

Sales and Marketing Expenses

We incurred advertising costs which are included in sales and marketing of $17,750 and $14,521 for the three months ended March 31, 2019 and 2018, respectively.

Leases

At inception of a contract, the Company determines whether the contract is or contains a lease. Further, the Company determines if the arrangement qualifies as an operating lease or a finance lease. Operating leases are included in operating lease right-of-use assets, operating lease liabilities - current portion and operating lease liabilities on the Company's consolidated balance sheet. The Company does not have any finance leases as of March 31, 2019 and January 1, 2019.

A right-of-use asset represents the Company's right to use the underlying asset for the lease term and the lease liabilities represent our obligation to make lease payments under the leasing arrangement. We recognize an operating lease right-of-use asset and operating lease liability at the arrangement's commencement date based upon the present value of the lease payments over the lease term. We utilize our incremental borrowing rate based on the information available at the commencement date in order to determine the present value of lease payments or the implicit rate when readily determinable. The Company's lease arrangements may include options to extend or terminate the lease arrangement. Such options are included in the determination of lease term when it is reasonably certain that the Company will exercise that option. The Company recognizes lease expense for lease payments on a straight-line basis over the term of the lease. The Company has made an accounting policy election for leases that at the commencement date have terms of twelve months or less to not recognize an operating lease right-of-use assets or operating lease liabilities on its balance sheet. Instead, the Company recognizes lease payments as an expense in accordance with the lease terms.

Fair Value of Financial Instruments

The Company records certain of its financial assets at fair value on a recurring basis as described below. Certain of the Company's other financial instruments, which include cash and cash equivalents, accounts receivable and accounts payable, approximate fair value because of their short-term maturities. We believe the fair value of our debt at March 31, 2019 and December 31, 2018 was approximately the same as its carrying amount as market conditions, including available interest rates, credit spread relative to our credit rating, and illiquidity, remain relatively unchanged from the issuance date of our debt obligations for a similar debt instrument and are classified as Level 3 within the fair value hierarchy. 

We account for financial assets using a framework that establishes a hierarchy that ranks the quality and reliability of the inputs, or assumptions, we use in the determination of fair value, and we classify financial assets and liabilities carried at fair value in one of the following three categories:

•Level 1 - quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets and liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

•Level 2 - observable prices that are based on inputs not quoted on active markets but corroborated by market data; and

•Level 3 - unobservable inputs when there is little or no market data available, thereby requiring an entity to develop its own assumptions. The fair value hierarchy gives the lowest priority to Level 3 inputs.

The following table presents the assets that are measured and recognized at fair value on a recurring basis classified under the appropriate level of the fair value hierarchy as of March 31, 2019 and December 31, 2018:

	March 31, 2019		December 31, 2018

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The ASU simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. This ASU is effective for an annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019 on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of ASU 2017-04 is not expected to have a material impact on our condensed consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments which requires the use of a new current expected credit loss ("CECL") model in estimating allowances for doubtful accounts with respect to accounts receivable, straight-line receivable and notes receivable. Receivables from revenue transactions, or trade receivables, are recognized when the corresponding revenue is recognized under ASC Topic 606, Revenue from Contracts with Customers. The CECL model requires that the Company estimate its lifetime expected credit loss with respect to these receivables and record allowances that when deducted from the balance of the receivables, represent the estimated net amounts expected to be collected. Given the generally short term nature of trade receivables, we do not expect to apply a discounted cash flow methodology. However, the Company will consider whether historical loss rates are consistent with expectations of forward-looking estimates for our trade receivables. In November 2018, the FASB issued ASU 2018-19 to clarify that operating lease receivables recorded by lessors are explicitly excluded from the scope of Topic 326. This ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. While we are still evaluating the impact of this guidance on our consolidated financial statements, we do not currently believe it will have a material impact upon adoption.

The following standard was adopted by the Company during the current period:

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)" which replaces the guidance on accounting for leases in Topic 840. The new guidance increases transparency and comparability among organizations by requiring lessees to recognize assets and liabilities on the balance sheet for most leases and disclose key information about leasing arrangements.

The Company adopted the new standard on January 1, 2019 using a modified retrospective transition approach, which involves applying the new standard to all leases existing at the date of the initial application with any cumulative impact of the adoption recorded to retained earnings. In addition, we elected the package of practical expedients permitted under the transition guidance which allows the Company to carry forward the historical lease classification. The adoption of Topic 842 has had a significant effect on our balance sheet, mostly related to (1) the recognition of new right-of-use assets and new lease liabilities on our balance sheet for our existing operating leases (most notably leases of office space and co-location space); and (2) the derecognition of existing assets (most notably prepaid rent), and existing liabilities (most notably deferred rent) related to such leases. It will not materially affect our earnings or cash flows. We recorded the following transactions on January 1, 2019:

• Recognized currently unrecognized right-of-use assets of $57.3 million net of deferred rent and lease incentives which were previously included in other liabilities.

• Recognized currently unrecognized lease liabilities of $64.5 million (based on the present value of the remaining minimum rental payments for existing operating leases).

•

Recognized an adjustment to retained earnings of $458 thousand related to release of deferred tax assets.

Acquisition of NewVoiceMedia

On October 31, 2018, the Company acquired 100% of the issued and outstanding shares of NewVoiceMedia Limited (“NewVoiceMedia”), a cloud Contact Center-as-a-Service (CCaaS) provider, for a purchase price of $350,179 paid in cash.

The acquisition was recorded as a business combination under ASC 805, with identifiable assets acquired and liabilities assumed provisionally recorded at their estimated fair value on the acquisition date. The initial accounting for the business combination is not complete because the evaluations necessary to assess the fair values of certain net assets acquired inclusive of deferred tax liabilities is still in process. The allocation of the purchase price may be modified up to one year from the date of the acquisition as more information is obtained about the fair value of assets acquired and liabilities assumed. Under the terms of the offer, NewVoiceMedia shareholders received cash in the amount of approximately $341 million as well as transactions costs incurred by NewVoiceMedia which were paid by the Company of approximately $9 million on the date of the acquisition.

The table below summarizes the NewVoiceMedia assets acquired and liabilities assumed as of October 31, 2018:

For the three months ended March 31, 2019, our effective tax rate was different than the statutory rate primarily due to a discrete period tax benefit of $4,749, which were recognized related to excess tax benefits on equity compensation for the three months ended March 31, 2019.

For the three months ended March 31, 2018, our effective tax rate was different than the statutory rate due to a permanent adjustment of $6,702 related to the new Global Intangible Low-Taxed Income ("GILTI") tax rules that were enacted as part of tax reform enacted in December 2017. In addition, the Company recorded a discrete period tax benefit of $15,307 which was recognized related to excess tax benefits on equity compensation recognized in the first quarter of 2018.

This footnote should be read in conjunction with the complete description of our financing arrangements under Note 7, Long-Term Debt and Revolving Credit Facility to our Annual Report on Form 10-K for the year ended December 31, 2018.

A schedule of long-term note and revolving credit facility at March 31, 2019 and December 31, 2018 is as follows:

	March 31, 2019		December 31, 2018

Revolving credit facility - due 2023	466,500		425,000
Total Long-term note and revolving credit facility	$	548,265	$	509,228

2018 Term Note and Revolving Credit Facility

On July 31, 2018, the Company replaced its 2016 Credit Facility previously consisting of a $125 million term loan and a $325 million revolving credit facility with the 2018 Credit Facility consisting of a $100 million senior secured term loan and a $500 million revolving credit facility. The co-borrowers under the 2018 Credit Facility are the Company and Vonage America Inc., the Company’s wholly owned subsidiary. Obligations under the 2018 Credit Facility are guaranteed, fully and unconditionally, by the Company’s other United States subsidiaries and are secured by substantially all of the assets of each borrower and each guarantor.

The Company used $232,000 of the proceeds available under our 2018 Credit Facility plus cash on hand to retire all of the debt outstanding under our 2016 Credit Facility and to cover transaction fees and expenses. Total transaction fees and expense incurred were $3,376, of which $474 was allocated to the term note and $2,813 was allocated to the revolving credit facility which will be amortized over the term of 2018 Credit Facility. The remaining $89 of transaction fees and expenses were expensed during the year ended December 31, 2018. The Company recognized a loss on extinguishment of debt of $14 which primarily consisted of the write off of previously deferred financing costs partially offset by the realization of a portion of gains associated with the interest rate swaps included in accumulated other comprehensive income during the year ended December 31, 2018. Remaining proceeds available from the undrawn revolving credit facility under our 2018 Credit Facility will be used for general corporate purposes and to fund potential additional acquisitions.

During the three months ended March 31, 2019, we made mandatory repayments of $2.5 million under the 2018 term note and borrowed $41.5 million under the revolving credit facility. In addition, the effective interest rate was 5.25% as of March 31, 2019.

As of March 31, 2019, we were in compliance with all covenants, including financial covenants, for the 2018 Credit Facility.

2016 Financing

During the three months ended March 31, 2018, we made mandatory repayments of $4.7 million under the term note and made discretionary repayments of $5.0 million under the revolving credit facility and borrowed $10.0 million under the revolving credit facility.

Interest Rate Swaps

On July 14, 2017, we executed on three interest rate swap agreements in order to hedge the variability of expected future cash interest payments related to the 2016 Credit Facility. The swaps have an aggregate notional amount of $150 million and were effective from July 31, 2017 through June 3, 2020 concurrent with the term of the 2016 Credit Facility. Under the swaps our interest rate is fixed at 4.7%. The interest rate swaps are accounted for as cash flow hedges in accordance with ASC 815, Derivatives and Hedging.

As of March 31, 2019 and December 31, 2018, the fair market value of the swaps was $1,278 and $1,859, respectively, which is included in other assets on our condensed consolidated balance sheet. The following table summarizes the effects of ASC 815 on the Company's accumulated OCI balance attributable to cash flow derivatives:

Commitments and Contingencies

Commitments and Contingencies

Litigation

From time to time we are subject to legal proceedings, claims, investigations, and proceedings in the ordinary course of business, including claims of alleged infringement of third-party patents and other intellectual property rights, commercial, employment, and other matters. From time to time, we receive letters or other communications from third parties inviting us to obtain patent licenses that might be relevant to our business or alleging that our services infringe upon third party patents or other intellectual property. In accordance with generally accepted accounting principles, we make a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss or range of loss can be reasonably estimated. These provisions, if any, are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. Litigation is inherently unpredictable. We believe that we have valid defenses with respect to the legal matters pending against us and are vigorously defending these matters. Given the uncertainty surrounding litigation and our inability to assess the likelihood of a favorable or unfavorable outcome in such matters and our inability to reasonably estimate the amount of loss or range of loss, it is possible that the resolution of one or more of these matters could have a material adverse effect on our condensed consolidated financial position, cash flows or results of operations.

Regulation

Telephony services are subject to a broad spectrum of state, federal and foreign regulations. Because of the uncertainty over whether Voice over Internet Protocol (“VoIP”) should be treated as a telecommunications or information service, we have been involved in a substantial amount of state and federal regulatory activity. Implementation and interpretation of the existing laws and regulations is ongoing and is subject to litigation by various federal and state agencies and courts. Due to the uncertainty over the regulatory classification of VoIP service, there can be no assurance that we will not be subject to new regulations or existing regulations under new interpretations, and that such change would not introduce material additional costs to our business. The Company continues to monitor federal regulations relating to net neutrality, rural call completion issues, number slamming, 911 access, access to telecommunication equipment and services by persons with disabilities, caller ID services, number portability, unwanted calls to reassigned numbers, and robocalling. As we continue to expand globally, these types of regulations are likely to be similarly enacted and enforced by the local regulatory authorities.    

State and Municipal Taxes

In accordance with generally accepted accounting principles, we make a provision for a liability for taxes when it is both probable that a liability has been incurred and the amount of the liability or range of liability can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. For a period of time, we did not collect or remit state or municipal taxes (such as sales, excise, utility, use, and ad valorem taxes), fees or surcharges (“Taxes”) on the charges to our customers for our services, except that we historically complied with the New Jersey sales tax. We have received inquiries or demands from a number of state and municipal taxing and 911 agencies seeking payment of Taxes that are applied to or collected from customers of providers of traditional public switched telephone network services. Although we have consistently maintained that these Taxes do not apply to our service for a variety of reasons depending on the statute or rule that establishes such obligations, we are now collecting and remitting sales taxes in certain of those states including a number of states that have changed their statutes to expressly include VoIP. In addition, many states address how VoIP providers should contribute to support public safety agencies, and in those states we remit fees to the appropriate state agencies. We could also be contacted by state or municipal taxing and 911 agencies regarding Taxes that do explicitly apply to VoIP and these agencies could seek retroactive payment of Taxes. As such, we have established reserves of $3,380 and $3,302 as of March 31, 2019 and December 31, 2018, respectively, as our best estimate of the potential tax exposure for any retroactive assessment.

Segment Reporting [Abstract]

Industry Segment and Geographic Information

Industry Segment and Geographic Information

ASC 280 "Segment Reporting" establishes reporting standards for an enterprise's business segments and related disclosures about its products, services, geographic areas and major customers. Under ASC 280, the method for determining what information to report is based upon the way management organizes the operating segments within the Company for making operating decisions and assessing financial performance. Our chief operating decision-maker reviews revenue and gross margin information for each of our reportable segments, but does not review operating expenses on a segment by segment basis. In addition, with the exception of goodwill and intangible assets, we do not identify or allocate our assets by the reportable segments.

Business

For our Business customers, we provide innovative, cloud-based UCaaS solutions, comprised of integrated voice, text, video, data, collaboration, and mobile applications over our flexible, scalable SIP based VoIP network. Through Nexmo, the Vonage API Platform, we also offer CPaaS solutions designed to enhance the way businesses communicate with their customers embedding communications into apps, websites and business processes. Together we have a robust set of product families tailored to serve the full range of the business value chain, from the SMB, market, through mid-market and enterprise markets. We provide customers with multiple deployment options, designed to provide the reliability and quality of service they demand. We provide customers the ability to integrate our cloud communications platform with many cloud-based productivity and CRM solutions, including Google’s G Suite, Zendesk, Salesforce’s Sales Cloud, Oracle, Clio, and other CRM solutions. In combination, our products and services permit our business customers to communicate with their customers and employees through any cloud-connected device, in any place, at any time without the often costly investment required with on-site equipment.

Consumer

For our Consumer customers, we enable users to access and utilize our services and features, via a single “identity,” either a number or user name, regardless of how they are connected to the Internet, including over 3G/4G, LTE, Cable, or DSL broadband networks. This technology enables us to offer our Consumer customers attractively priced voice and messaging services and other features around the world on a variety of devices.

For our segments we categorize revenues as follows:

Services revenues. Services revenues consists primarily of revenue attributable to our communication services for Consumer and Software Defined Wide Area Network, or SD-WAN, UCaaS and CPaaS services for Business,

Access and product revenues. Product revenues include equipment sold to customers, shipping and handling, professional services, and broadband access, as well as revenues associated with providing access services to Business customers.

USF revenues. USF revenues represent fees passed on to customers to offset required contributions to the USF.

For our segments we categorize cost of revenues as follows:

Services cost of revenues. Services cost of revenues consists of costs associated with network operations and technical support personnel, communication origination, and termination services provided by third party carriers and excludes depreciation and amortization.

Access and product cost of revenues. Product cost of revenues includes equipment sold to customers, shipping and handling, professional services, cost of certain products including equipment or services that we give customers as promotions, and broadband access, as well as costs associated with providing access services to Business customers.

USF cost of revenues. USF cost of revenues represents contributions to the Federal USF and related fees.

Accounting Policies [Abstract]

Unaudited Interim Financial Information

Unaudited Interim Financial Information

The accompanying unaudited interim condensed consolidated financial statements and information have been prepared in accordance with accounting principles generally accepted in the United States and in accordance with the SEC's regulations for interim financial information and with the instructions for Form 10-Q. Accordingly, they do not include all of the information and disclosures required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, these financial statements contain all normal and recurring adjustments considered necessary to present fairly the Company's financial position, results of operations, comprehensive income, cash flows, and stockholders’ equity for the periods presented. The results for the three months ended March 31, 2019 are not necessarily indicative of the results to be expected for the full year.

These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2018 filed with the Securities and Exchange Commission on February 27, 2019.

Use of Estimates

Use of EstimatesOur condensed consolidated financial statements and notes thereof are prepared in conformity with accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and the accompanying notes. Actual results could differ materially from these estimates.

Reclassifications

ReclassificationsReclassifications have been made to our condensed consolidated financial statements for the prior year periods to conform to classifications used in the current year periods. The reclassifications did not affect results of operations or net assets.

Cost of Revenues

Cost of RevenuesCost of revenues excludes depreciation and amortization expense of $9,418 and $6,434 for the three months ended March 31, 2019 and 2018, respectively. In addition, costs of goods sold included in cost of revenues during the three months ended March 31, 2019 and 2018 were $5,628 and $6,297, respectively.

Sales and Marketing Expenses

Sales and Marketing ExpensesWe incurred advertising costs which are included in sales and marketing of $17,750 and $14,521 for the three months ended March 31, 2019 and 2018, respectively.

Lessee, Leases [Policy Text Block]

Leases

At inception of a contract, the Company determines whether the contract is or contains a lease. Further, the Company determines if the arrangement qualifies as an operating lease or a finance lease. Operating leases are included in operating lease right-of-use assets, operating lease liabilities - current portion and operating lease liabilities on the Company's consolidated balance sheet. The Company does not have any finance leases as of March 31, 2019 and January 1, 2019.

A right-of-use asset represents the Company's right to use the underlying asset for the lease term and the lease liabilities represent our obligation to make lease payments under the leasing arrangement. We recognize an operating lease right-of-use asset and operating lease liability at the arrangement's commencement date based upon the present value of the lease payments over the lease term. We utilize our incremental borrowing rate based on the information available at the commencement date in order to determine the present value of lease payments or the implicit rate when readily determinable. The Company's lease arrangements may include options to extend or terminate the lease arrangement. Such options are included in the determination of lease term when it is reasonably certain that the Company will exercise that option. The Company recognizes lease expense for lease payments on a straight-line basis over the term of the lease. The Company has made an accounting policy election for leases that at the commencement date have terms of twelve months or less to not recognize an operating lease right-of-use assets or operating lease liabilities on its balance sheet. Instead, the Company recognizes lease payments as an expense in accordance with the lease terms.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The Company records certain of its financial assets at fair value on a recurring basis as described below. Certain of the Company's other financial instruments, which include cash and cash equivalents, accounts receivable and accounts payable, approximate fair value because of their short-term maturities. We believe the fair value of our debt at March 31, 2019 and December 31, 2018 was approximately the same as its carrying amount as market conditions, including available interest rates, credit spread relative to our credit rating, and illiquidity, remain relatively unchanged from the issuance date of our debt obligations for a similar debt instrument and are classified as Level 3 within the fair value hierarchy. 

We account for financial assets using a framework that establishes a hierarchy that ranks the quality and reliability of the inputs, or assumptions, we use in the determination of fair value, and we classify financial assets and liabilities carried at fair value in one of the following three categories:

•Level 1 - quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets and liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

•Level 2 - observable prices that are based on inputs not quoted on active markets but corroborated by market data; and

•Level 3 - unobservable inputs when there is little or no market data available, thereby requiring an entity to develop its own assumptions. The fair value hierarchy gives the lowest priority to Level 3 inputs.

The following table presents the assets that are measured and recognized at fair value on a recurring basis classified under the appropriate level of the fair value hierarchy as of March 31, 2019 and December 31, 2018:

	March 31, 2019		December 31, 2018

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The ASU simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. This ASU is effective for an annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019 on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of ASU 2017-04 is not expected to have a material impact on our condensed consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments which requires the use of a new current expected credit loss ("CECL") model in estimating allowances for doubtful accounts with respect to accounts receivable, straight-line receivable and notes receivable. Receivables from revenue transactions, or trade receivables, are recognized when the corresponding revenue is recognized under ASC Topic 606, Revenue from Contracts with Customers. The CECL model requires that the Company estimate its lifetime expected credit loss with respect to these receivables and record allowances that when deducted from the balance of the receivables, represent the estimated net amounts expected to be collected. Given the generally short term nature of trade receivables, we do not expect to apply a discounted cash flow methodology. However, the Company will consider whether historical loss rates are consistent with expectations of forward-looking estimates for our trade receivables. In November 2018, the FASB issued ASU 2018-19 to clarify that operating lease receivables recorded by lessors are explicitly excluded from the scope of Topic 326. This ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. While we are still evaluating the impact of this guidance on our consolidated financial statements, we do not currently believe it will have a material impact upon adoption.

The following standard was adopted by the Company during the current period:

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)" which replaces the guidance on accounting for leases in Topic 840. The new guidance increases transparency and comparability among organizations by requiring lessees to recognize assets and liabilities on the balance sheet for most leases and disclose key information about leasing arrangements.

The Company adopted the new standard on January 1, 2019 using a modified retrospective transition approach, which involves applying the new standard to all leases existing at the date of the initial application with any cumulative impact of the adoption recorded to retained earnings. In addition, we elected the package of practical expedients permitted under the transition guidance which allows the Company to carry forward the historical lease classification. The adoption of Topic 842 has had a significant effect on our balance sheet, mostly related to (1) the recognition of new right-of-use assets and new lease liabilities on our balance sheet for our existing operating leases (most notably leases of office space and co-location space); and (2) the derecognition of existing assets (most notably prepaid rent), and existing liabilities (most notably deferred rent) related to such leases. It will not materially affect our earnings or cash flows. We recorded the following transactions on January 1, 2019:

• Recognized currently unrecognized right-of-use assets of $57.3 million net of deferred rent and lease incentives which were previously included in other liabilities.

• Recognized currently unrecognized lease liabilities of $64.5 million (based on the present value of the remaining minimum rental payments for existing operating leases).

•

Recognized an adjustment to retained earnings of $458 thousand related to release of deferred tax assets.
