EVOLUTION OF VONAGE

Founded in 2001, Vonage became a leading provider of broadband communication services using the Company's innovative Voice over Internet Protocol, or VoIP, technology platform offering feature-rich, low-cost communication services. Beginning in November 2013 and continuing through September 2015, Vonage acquired five companies: Vocalocity, Inc., Telesphere Networks Ltd., Simple Signal Inc., gUnify LLC and iCore Networks Inc. With these acquisitions, Vonage began its execution of a pivot from a solely residential communications provider to establishing the foundation of Unified Communications as a Service, or UCaaS, available to service the needs of businesses to improve how they communicate with their customers and their employees.
In June 2016, Vonage completed the acquisition of Nexmo, Inc., a global leader in the Communications Platform as a Service, or CPaaS, sector of the cloud communications market. The acquisition of Nexmo accelerated Vonage's growth strategy to provide application program interfaces, or APIs, for text messaging and voice communications, allowing developers and enterprises to embed contextual, programmable communications into mobile apps, websites and business systems.
In August 2018, Vonage acquired TokBox Inc., an industry leader in WebRTC programmable video that enables developers and enterprises to integrate live video into websites, mobile apps and IoT devices with only a few lines of code. The acquisition of TokBox meaningfully broadened Vonage's API capabilities by adding video to its existing services in voice, SMS and IP messaging.
In October 2018, Vonage completed the acquisition of NewVoiceMedia Limited, an industry-leading cloud Contact Center as a Service, or CCaaS, provider. This acquisition enabled Vonage to combine its robust UCaaS and CPaaS solutions with NewVoiceMedia's pure-play cloud contact center offerings, culminating in the Company's ability to provide an end-to-end communication experience for a company's employees and its customers.

The communications industry is undergoing a global leadermajor transformation from dedicated communications applications and devices to communications embedded in other applications and devices where the CPaaS segmentcommunications happens within the context of those applications. For example, when calling or messaging a taxi driver, consumers can do this within the taxi app which has all the necessary context such as the pickup location and payment method, resulting in a better experience for both parties. Similarly, when contacting a company consumers can communicate within the context of the company’s branded mobile app or website and agents within the context of their CRM desktop application, delivering a better experience for consumers and improving productivity for contact center agents. We call this type of communications “contextual” because it is context rich and delivers a better experience. This trend is enabled by a new category of cloud communications market, providing innovative communication APIs for textplatforms that enable software developers to build communications capabilities such as messaging and voice calling within their applications without having to build or maintain communications allowing developers andinfrastructure. Programmable communications via APIs enable enterprises to embedimprove the ways they engage their customers through personalized and contectual communications for deeper engagement and more meaningful relationships.
While innovative software companies were the early adopters of cloud communication platforms, over time virtually all companies will benefit from the new approach as part of their digital transformation journey. As more startups disrupt existing industries, established enterprises will innovate with communications APIs in order to more effectively compete with the new entrants and with their traditional competitors. Over time enterprises of all sizes will adopt contextual communications to deliver better business outcomes.

Consumer
Our home telephone replacement services are offered to customers through several service plans with different pricing structures. The service plans include basic features such as voicemail, call waiting, and call forwarding as well as unique features such as Simulring, Visual Voicemail and Extensions. We also charge for local and international calling outside of plan limits. We also charge for local and international calling outside of plan limits.
We have two primary Consumer offerings:offerings available in the United States: Vonage World and Vonage North America. For a flat monthly fee, Vonage World customer plans include unlimited domestic calling (U.S., Canada, and Puerto Rico) and unlimited calling to landline phones in more than 60 countries, including India, Mexico, and China, and unlimited calling to mobile phones in certain of those countries. The Vonage North America plan includes unlimited calling across the U.S., Canada, Mexico and Puerto Rico. Each of our Consumer calling plans provides a number of basic features including call waiting, caller ID with name, call forwarding, and voicemail. Our plans also include unlimited Vonage Visual Voicemail, which is “readable voicemail” delivered via email or SMS text message, Vonage Extensions, which extends the plan, and in-boundinbound calling, to additional phone numbers and devices, and selective call block, which allows users to block unwanted calls. We also offer, in some cases for additional fees, features such as area code selection, virtual phone number, and web-enabled voicemail.
Our mobile services include enhancements Additionally, we also provide similar product offerings to our Consumer calling plans as well as mobile applications that can be initially downloaded for iPhone ® , iPad ® , iPod touch ® ,customers in both Canada and Android ® OS devices for free.the United Kingdom.
In order to access our consumer services, a customer need only connect a standard telephone to a broadband Internet connection through a small Vonage-enabled device. In order to access our business services, a customer need only connect through a VoIP-enabled telephone. After connecting the device, our customers can use their telephone to make and receive calls. Vonage-enabled devices allow customers to use the Internet connection for their computer and telephones at the same time while ensuring a high quality calling experience. We also offer a cordless multi-phone system solution. Our plug-and-play Vonage-enabled devices permit portability as customers can take their Vonage device to different locations where broadband service is available. We generally have not charged new customers for the adapters permitting use of our service.

NETWORK OPERATIONS
The Vonage network uses our customer’s existing or Vonage procured high-speed broadband Internet service to allow calls over the Internet either from a standard telephone through a Vonage-enabled device or through soft phone software or mobile client applications. Our UCaaS services are not dependent on any specific type or provider of Internet service, and our customers are free to change their Internet service provider in response to a competitive alternative, or because they have moved to a different location. For many of our Vonage PremierEnterprise customers, our UCaaS services are delivered over the Company's private, nationwide, fault tolerant, secure IP MPLS network under multi-year contracts to provide the high level of interconnection quality and
the ability to offer service level agreements, (SLA)or SLA, guaranteeing certain levels of voice service performance.
Our network is scalable and geographically distributed for robustness, high availability, and reliability across multiple call processing sites, using regional data interconnection points, where calls to non-Vonage customers are interconnected with the public switched telephone network. We periodically assess the locations of our regional data connection points in connection with efforts to improve the quality of and efficiency in delivering our service. Our interconnections with the public switched telephone network, or IP/SIP networks, are made pursuant to commercial agreements we have with several telecommunications providers. Under these agreements, we transfer calls originated by our customers to other carriers who connect the call to the called party or connect peer to peer. We have a varying degree of settlement arrangements with our carrier partners for indirect third party or direct termination of our calls. The calls are routed from our network to other carriers’ interconnected circuits at co-location facilities in which we lease space. This method of connecting to the public switched telephone or IP/SIP networks allows us to expand capacity quickly, as necessary to meet call volume, and to provide redundancy within our network.
Because Vonage’s system is standards based and not constrained to use any specific broadband service provider to connect to our customers, we can centrally manage and share resources across our customer base to minimize capital investment when entering new markets.
The following are also important in supporting our network operations:
Network Operations Center.   We currently maintain a network operations center at our headquarters with monitoring redundancies at several points within our network. The network operations center monitors and manages the status and health of our network elements, allowing us to manage our network in real time, respond to alert notifications, and re-route network traffic as needed. We pursue a multi-faceted approach to managing our network to ensure high call quality and reliable communications services to our customers. For Business customers, we have operational centers on-site to monitor and manage network access traffic. We may consolidate these network operations centers in the future if greater efficiencies can be obtained.
Back Office Systems. In addition to our network management systems, we have developed a number of software systems that enable us to manage our network and service offerings more efficiently and effectively. Key aspects of these systems include:
Network Quality Metrics. We have implemented a suite of advanced Big Data analysis tools that allow us to monitor and troubleshoot the performance of our calling and data network, customer premises equipment, and other associated calling elements in near real-time. This suite is proprietary and was developed specifically to address the needs that Vonage has in monitoring, analyzing, understanding, troubleshooting, maintaining, and operating a world-class consumer VoIP platform.  
Web Portal. We provide a fully functional customer Web portal that allows our customers to configure and manage almost all aspects of their service on the Internet without requiring intervention of a customer-care representative. The portal permits customers to add and change features and phone numbers, update billing information, and access call usage and billing details.
Emergency Calling Service and Enhanced 911 Service.  We have deployed E-911 service to approximately 99.99% of our U.S. consumer and small and home office customer base that is comparable to the emergency calling services provided to customers of traditional wireline telephone companies in the same area. Our E-911 service does not support the calls of our soft phone software users. The emergency calls of our soft phone software users are supported by a national call center. Not all Vonage products require 911 service capabilities, such as our mobile client products but we are fully compliant with E911 requirements of the Federal Communications Commission ("FCC") for VOIP Interconnected providers. To enable us to effectively

4     VONAGE ANNUAL REPORT 2016



deploy and provide our E-911 service, we maintain an agreement with a provider that assists us in delivering emergency calls to an emergency service dispatcher at the public safety answering point, or PSAP, in the area of the customer’s registered location and terminating E-911 calls. We also contract for the national call center that operates 24 hours a day, seven days a week to receive certain emergency calls and for the maintenance of PSAP databases for the purpose of deploying and operating E-911 services. The databases include contact, technical infrastructure, boundary, and routing information for delivery of calls to a PSAP or emergency service providers in the United States.
Local Number Portability. Our system allows our telephone replacement customers to port telephone numbers, which allows new customers to retain their existing telephone numbers when subscribing to our services. We rely on agreements with two service providers to facilitate the transfer of customer telephone numbers. In addition, we have engaged a provider that performs the third party verification of pertinent local number portability information from our subscribers prior to porting a customer from a local telephone company to us.
Security.  We have developed a service architecture and platform that uses industry-standard security techniques and allows us to remotely manage customer devices. Any Vonage-enabled device used by our customers can be securely managed by us, and these devices use authentication mechanisms to identify themselves to our service in order to place and receive calls. We regularly update our protocols and systems to protect against unauthorized access. As discussed in "Item 1A Risk Factors", security breaches and other cybersecurity or technological risks could compromise our information, systems and network and expose us to liability, which could have a material adverse effect on our business, financial condition, and operating results.
MARKETING
Our marketing objective is to help drive growth and revenue across our business and consumer markets. We employ an integrated multi-channel approach to marketing, whereby we evaluate and focus our efforts on efficient marketing vehicles to accomplish our goals with the greatest return on investment. To do this, we make use of both broad-reaching and highly-targeted media channels.
For our business customers, our primary source of lead acquisition is digital marketing in the form of search engine marketing, digital advertising, social media advertising, and affiliate programs. We also utilize database marketing and lead aggregators to source business leads. We use direct marketing and account-based marketing to help source leads and create interest in our solutions. We have a significant strategy of using third-party and proprietary events to source business leads and convert prospects.
For our residential customers, we have highly optimized our acquisition approach and focus mainly on digital advertising channels.

6     VONAGE ANNUAL REPORT 2018



We make use of marketing research to gain consumer insights into brand, product, and service performance, and utilize those learnings to improve our messaging and media plans. Market research is also leveraged in the areas of testing, retention marketing, and product marketing to ensure we bring compelling products and services to market for our customers.
We believe our brand is a meaningful factor for customers as they consider business services. We invest in our brand in order to retain and expand our customer base and to position Vonage as a technology leader that delivers innovative, unified communication services, serving the full range of businesses and Enterprises.enterprises. We expect these investments to continue as we further establish Vonage as a leading business services brand.

Additionally, Contact Center solutions are commonly integrated into Enterprise solutions
Developer Ecosystem
Our API platform products are principally adopted and consumed by software developers all over the world. Given the nature of the business, we invest significant time and effort to build, recruit, and maintain developers and various software ecosystems. We have a large developer ecosystem worldwide with over 700,000 registered developers.
Field Sales and Inside Sales - SMB and Midmarket
We utilize our team of sales agents, primarily based in geographic territories comprising customers and prospects, which we refer to as our field sales team, to market and sell our business services. These field sales agents utilize a consistent, automated, highly-structured sales process to effectively educate prospective customers regarding our services. We have developed a scalable model applicable to both existing and new markets. We now have field sales presence in 20 markets within the United States and made significant expansion into new markets globally primarily supporting Nexmo.

We now have a broad and deep coverage of the U.S. market through a network of over 20,000 sub agents and resellers.
Enterprise Sales
In order to continue to expand in the Enterprise segment, which we define as businesses larger than 1,000 seats, Our enterprise sales organization is uniquely positioned to provide high quality business services for Enterprise, through our fully managed solution, which utilizes BroadSoft’s enterprise-grade call processing platform, with a broad portfolio of products delivered over our own private, national MPLS network, with 21 Points-of-Presence (POPs) across the country and our own team of service delivery project managers using our proprietary provisioning tool Zeus, as well as our industry leading CPaaS products.
Retail Sales
In addition to our inside sales channel, we also offer our consumer services through our retail channel. In 2016, as part of our continued efforts to lowercustomer experience while reducing customer acquisition costs, we shifted our retail strategy to a grab-and-go strategy within large retailers to better leverage the strength of the Vonage brand. We believe that the availability of our services through premier retailers, with well-located shelf placement increases our ability to acquire mainstream consumers by reaching them in a familiar and interactive shopping environment. National and regional retailers provide Vonage with a wide footprint to distribute our service. Concurrently, we have also reduced our use of the assisted-selling face-to-face channel, which had a higher customer acquisition cost.
Customer Support
Consumer. We offer our customers support 24 hours a day, seven days a week through both our comprehensive online account management website and our toll free number. Many customers use our self-service website when they have a question or problem with their service and are able to resolve their concerns online without needing to speak to a customer care representative. Our customers can manage almost all aspects of their accounts online. This capability empowers our customers through self-service and reduces our customer care expenses.
costs.

57     VONAGE ANNUAL REPORT 20162018




INTELLECTUAL PROPERTY
Customers who cannot or do not wish to resolve their questions through our website may contact a customer care representative through our toll free number. We staff our customer care organization through a combination of ourcurrently own employees and outsourced customer care representatives. All new customer care representatives are trained through an established program developed by Vonage. We also have a separate team that provides advanced technical support for resolving customers’ complex issues. We use extensive monitoring of call quality and customer satisfaction scores to determine additional training or coaching requirements for individual associates and to drive continuous improvement in our processes, policies, and technology. We offer support in English, Spanish, Tagalog and French Canadian.
Small and Medium Businesses. We have specialized teams of customer care representatives to work with customers in every stage of their life cycle, including porting specialists to transfer (port) existing phone numbers, an order entry team to help customers bring their new phone system online,over 200 issued U.S. patents as well as billinga number of foreign patents and product specialists. Customers can also utilize our extensive online support resources, complete with cataloged feature descriptions, how-to videospending U.S. and other key resources to help them enable the many system features.
Additionally, our representatives have ready access to a full support team - from technical support pros and billing specialists, to engineers and product experts.
Medium and Large Enterprise. Our larger business customers benefit from a robust service delivery team comprised of team members specializing in project management, voice and data provisioning, and line number porting.
Billing
All customer billing for our communication services is automated. We bill in advance for monthly recurring services and fees. We collect all fees from our customers’ credit card, debit card, checks, wire transfer, ACH or electronic check payment (“ECP”). All usage related charges are billed no more than 30 days in arrears. By collecting monthly subscription fees in advance and certain other charges within the same billing cycle as they are incurred, we are able to reduce the amount of accounts receivable that we have outstanding, thus allowing us to have lower working capital requirements. Collecting in this manner also helps us mitigate bad debt exposure, which is recorded as a reduction to revenue. If a customer’s payment is declined or returned we generally suspend services. Historically, in most cases, we are able to correct the problem with the customer within the current monthly billing cycle. Generally, for our consumer services, if the customer’s credit card, debit card or ECP cannot be successfully processed during three billing cycles (i.e. the current and two subsequent monthly billing cycles), we terminate the account. For customers in grace or suspend status we have enabled one-time cash payments through an arrangement with MoneyGram. Generally, for our Essentials customers, we will make several attempts to collect payment. If after approximately fifteen days we have not successfully collected the balance due, the customer’s account services are suspended. If after 30 days the account is still in a suspended status, the account is cancelled. Generally, for our Premier customers, if after 60 days we have not successfully collected the balance due, the customer’s account services are suspended. If after seven additional days the account is still in a suspended status, the account in cancelled. For our Nexmo customers, we require prepayment from our smaller customers. For Nexmo's larger customers we issue invoices in arrears for usage. For Nexmo's postpaid customers, we review customers on a case by case basis before suspending or terminating services.
INTELLECTUAL PROPERTY
We believe that our technological position depends primarily on the experience, technical expertise, and creative ability of our employees.foreign patent applications. We routinely review our technological developments with our technology staff and business units to identify the aspects of our technology that provide us with a technological or commercial advantage and seek intellectual property (including patent)and patent protection
as appropriate to protect such key proprietary technology in the United States and internationally, based on our assessment in light of applicable law. Our company policies require our employees to assign intellectual property rights developed in the scope of or in relation to our business to us and to treat proprietary know-how and materials as our confidential information.
In addition to developing technology and intellectual property, from time to time we evaluate opportunities for potential licensing and acquisition of third-party technology and intellectual property that may provide us with a strategic or commercial advantage in exchange for royalties or other consideration. As a result of these efforts, weWe have acquired multiple U.S. and foreign patents, and obtained licenses to numerous other patents. From time to time we receive letters from third parties inviting us to obtain patent licenses that might be relevant to our business. From time to time, we also have become involved in litigation alleging that our products or services infringe on third party patents or other intellectual property rights. See “Item 3. - Legal Proceedings-IP Matters.”
We are the owner of numerous United States and international trademarks and service marks and have applied for registration of our trademarks and service marks in the United States and abroad to establish and protect our brand names as part of our intellectual property strategy. Examples of our registered marks include Vonage®, Vonage Mobile®, Vonage Extensions®, and Nexmo ®.
We endeavor to protect our internally developed systems and technologies and maintain our trademarks and service marks. Typically, we enter into confidentiality agreementsCOMPETITION
In connection with our employees, consultants, partners, customers,cloud communications products, we face competition from the traditional telephone and cable companies as discussed below, as well as from vendors of premises-based solutions or hosted solutions including the following:
Independent cloud service providers;
Premises-based business communication equipment providers;
Hosted communication services providers;
Traditional technology companies; and
Emerging competitors in an effort to control access to and dissemination of our technology software, business plans, documentation, and other proprietary information and trade secrets.
COMPETITION
companies.

As the cloud communications market evolves, and the convergence of voice, video, messaging, mobility and data networking technologies accelerates, we may face competition in the future from companies that do not currently compete in the market, including companies that currently compete in other sectors, companies that serve consumers rather than business customers, or companies which expand their market presence to include cloud communications.
We face continued strong competition from traditional telephone companies, cable companies, wireless companies, alternative communication providers, direct unified communications providers, legacy consumer VOIP businesses, large technology incumbents, and collaboration providers in the consumer, mobile, SMB and enterprise markets. Because most of our target customers are already purchasing communications services from one or more of these providers, our success is dependent upon our ability to attract these customers away from their existing providers. We believe that the principal competitive factors affecting our ability to attract and retain customers are price, call quality, brand awareness, customer service, network and system reliability, service features and capabilities, scalability, usability, simplicity, mobile integration and mobile integration.
Traditional telephone and cable companies
The traditional telephone and cable companies are our primary competitors for our broadband telephone services. Traditional telephone companiesthe unique ability to deliver CPaaS communications tools to business customers in particular have historically dominated their regional markets. These competitors include AT&T, Verizon and CenturyLink, as well as rural incumbents such as Frontier Communications. Cable company competitors include companies such as Altice, Charter Communications, Comcast Corporation, and Cox Communications. These traditional phone and cable company competitors are substantially larger and better capitalized than we are and have the advantage of a large existing customer base. Many of these competitors are continuing to make substantial investments in delivering broadband Internet access, VoIP phone service, and cable television to their customers and they often have larger product development and marketing budgets than us. Providing home phone, Internet access, and cable television to many of our existing and potential customers may enhance their image as trusted providers of services.
The traditional phone and cable companies own networks that include a “last mile” connection to substantially all of our existing and potential domestic customers as well as the places our customers

6     VONAGE ANNUAL REPORT 2016


Table of Contents

call domestically. As a result, the vast majority of the calls placed by a Vonage customer are carried over the “last mile” by a traditional phone company, and we indirectly pay access charges to these competitors for each of these calls. In contrast, traditional wireline providers do not pay us when their customers call our customers.
Cable companies and, in many cases traditional phone companies, are also aggressively using their existing customer relationships to bundle services. For example, they bundle Internet access, cable television, and home phone service with an implied price for the phone service that may be significantly below ours. In addition such competitors may in the future require new customers or existing customers making changes to their service to purchase voice services when purchasing high speed Internet access. Certain traditional phone companies are also able to bundle wireless telephone service. Many of these competitors are able to advertise on their local access channels with no significant out-of-pocket cost and through mailings in bills with little marginal cost. They also receive advertising time as part of their relationships with television networks and are able to use this time to promote their telephone service offerings.
Traditional phone and cable companies’ ownership of Internet connections to our customers could enable them to detectUCaaS and interfere with the completion of our customers’ calls. While we are not aware of any such occurrence, it is unclear whether current regulations would permit these companies to degrade the quality of, give low priority to or block entirely the information packets and other data we transmit over their lines. In addition, these companies may attempt to charge their customers more for using our services.
Many traditional phone and cable companies routinely send technicians to customers’ premises to initiate service. Although this is expensive, it also can be more attractive to customers than installing their own router. In addition, these technicians may install an independent source of power, which can give customers assurance that their phone service will not be interrupted during power outages.
The traditional phone and cable companies have long-standing relationships with regulators, legislators, lobbyists, and the media. This can be an advantage for them because legislative, regulatory or judicial developments in our rapidly evolving industry could have a negative impact on us.
In many cases, we charge prices that are lower than prices charged by the traditional phone and cable companies. We believe that we also currently compete successfully with the traditional phone and cable companies on the basis of the features we offer that they may not (such as area code selection, portable service, virtual phone numbers, and readable voice mail). We offer many of these features at no extra charge.
Wireless telephone companies
We also compete with wireless phone companies, such as AT&T, Sprint, T-Mobile, and Verizon Wireless, for both our broadband telephone services, international long distance, and our mobile services. Some consumers use wireless phones, instead of VoIP phones, as a replacement for a wireline phone. Also, wireless phone companies increasingly are providing wireless broadband Internet access to their customers. As wireless providers offer more minutes at lower prices and other services that improve calling quality, their services have become more attractive to households as a competitive replacement for wireline service. In addition, wireless providers are also offering standalone wireless home services as well as the ability to link multiple devices for telephony service. Wireless telephone companies have a strong retail presence and have significant financial resources. We are developing next-generation services to meet the emerging needs of mobile and other connected device users by delivering easy-to-use applications that provide significant cost savings in large existing markets. We believe that our efforts will capitalize on favorable trends including the proliferation of low or no-cost Wi-Fi and other broadband around the world, accelerating smart phone adoption rates, and the growth of social communities.


Alternative communications providers
We also compete against alternative communication providers such as Twilio, magicJack, Ooma, Skype, and WhatsApp, some of which are larger than us and have the ability to devote greater resources to their communications services. Some of these service providers, including Internet product and software companies, have chosen to sacrifice telephony revenue in order to gain market share or attract users to their platform and have offered their services at low prices or for free. While not all of these competitors currently offer the ability to call or be called by anyone not using their service, line portability, E911 service, and customer service, in the future they may integrate such capabilities into their serviceCCaaS offerings. As we continue the introduction of applications that integrate different forms of voice, video, messaging, and other services over multiple devices, we face competition from emerging competitors focused on similar integration, as well as from alternative communication providers.
There is a continuing trend toward consolidation of competitive companies, including the acquisition of alternative communication providers by Internet product and software companies with significant resources. In addition, certain of our competitors have partnered and may in the future partner with other competitors to offer products and services, leveraging their collective competitive positions. We also are subject to the risk of future disruptive technologies, which could give rise to significant new competition.
In connection with our international long distance business, we face competition from low-cost international calling cards and VoIP providers in addition to traditional telephone companies, cable companies, and wireless companies.
In connection with our cloud communications products, we face competition from the traditional telephone and cable companies discussed above, as well as from vendors of premises-based solutions and/or hosted solutions, including the following:
Independent cloud services providers such as Twilio, EvolveIP, Jive, Mitel, RingCentral, ShoretelConnect, Fuse Networks, West Unified Communications Services, and 8x8;
Premises-based business communication equipment providers such as Alcatel-Lucent, Avaya, Cisco, Huawei, Interactive Intelligence, Mitel, NEC, Shoretel, and Unify;
Hosted communication services providers based on technologies from Avaya, Broadsoft, Cisco, Microsoft, Mitel, Unify and other vendors of technology platforms;
Traditional technology companies such as Microsoft and Google; and
Emerging competitors in technology companies such as Amazon, Salesforce, and Facebook.
As the cloud communications market evolves, and the convergence of voice, video, messaging, mobility and data networking technologies accelerates, we may face competition in the future from companies that do not currently compete in the market, including companies that currently compete in other sectors, companies that serve consumer rather than business customers, or companies which expand their market presence to include cloud communications.
SEGMENT 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-makers review revenue and gross margin information for each of our reportable segments, but do 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.

Table of Contents

Historically, we have had two operating segments that we have aggregated for reporting purposes. In 2016, as a result of the acquisition of Nexmo, we no longer meet the aggregation criteria for operating segments and now have the following two reportable segments:
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 (SIP) based Voice over Internet Protocol, or VoIP, network. Through Nexmo, the Vonage API Platform, we also offer Communications Platform as a Service, or 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 small and medium business, or 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 UCaaS 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, 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.

You should carefully consider the risks below, as well as all of the other information contained in this Annual Report on Form 10-K and our financial statements and the related notes included elsewhere in this Annual Report on Form 10-K, in evaluating our company and our business. Any of these risks could materially adversely affect our business, financial condition and results of operations and the trading price of our common stock.
For the financial information discussed in this Annual Report on Form 10-K, other than per share and per line amounts, dollar amounts are presented in thousands, except where noted.
If we are unable to compete successfully, we could lose market share and revenue.
The Unified Communications as a service, or UCaaS,business cloud communications markets and Communications Platform as a service, or CPaaS, industries,consumer services market in which we refer to as our business services,participate are highly competitive. We also provide consumer services. We face intense competition from a broad set of companies, including:

traditional telephone and wireless service providers such as AT&T, Verizon Communications, CenturyLink, Sprint, T-Mobile, and Verizon Wireless;
cable companies such as Altice, Cablevision, Comcast Corporation, Cox Communications, and Spectrum; and
software as a service (SaaS) companies, andcontact center as a service companies, other alternative communication providers, such as Twilio, EvolveIP, Jive, Mitel, RingCentral, Shoretel, Thinking Phone, West Unified Communications Services, 8x8 and other providers of cloud communications services.services; and
traditional telephone, wireless service providers, cable companies and alternative communications providers with consumer offerings
Many of these providers are substantially larger and better capitalized than weus are and have the advantage of greater name and brand name recognition and a large existing customer base. These service providers may have the ability to devote greater resources to their communications services and may be able to respond more quickly and effectively than we can to new or changing opportunities. Because most of our target Consumer customers are already purchasing communications services from one or more of these providers, our success is dependent upon our ability to attract target customers away from their existing providers. Our competitors' financial resources may allow them to offer services at prices below cost or even for free in order to maintain and gain market share or otherwise improve their competitive positions. Some of our competitors also could use their greater financial resources to develop and market telephony and messaging services with more attractive features and more robust customer service. In addition, because of the other services our competitors provide, some of these service providers choose to offer cloud communications services as part of a bundle that includes other products, such as high speed Internet access and wireless telephone service. These bundled offers may enable our competitors to offer cloud communications services at prices with which we may not be able to compete or to offer functionality that integrates cloud communications services with their other offerings, both of which may be more desirable. As we continue the introduction of applications that integrate different forms of voice, video, and messaging services over multiple devices, we face competition from emerging competitors focused on similar integration, as well as from established alternative communication providers. Any of these competitive factors could make it more difficult for us to attract and retain customers, reduce our market share and revenues, or cause us to lower our prices or offer additional features that may result in additional costs without commensurate price increases. In order to compete with such service providers, we may have to reduce our prices, which would impair
our profitability, or offer additional features that may cause us to incur additional costs without commensurate price increases.
To the extent that these or other companies strengthen their offerings, to small and medium businesses, we may have to reduce our prices, increase promotions, or offer additional features, which may adversely impact our revenues and profitability.
With the addition of NewVoiceMedia and our offering of cloud-based contact center services, we also compete with large legacy technology vendors that offer on-premise enterprise telephony and contact center systems and legacy on-premise software companies that come from a computer-telephony integration heritage. These companies are supplementing their traditional on-premise contact center systems with cloud offerings, either through acquisition or in-house development. Additionally, we compete with vendors that historically provided other contact center services and technologies and expanded to offer cloud contact center software. We also face competition from smaller contact center service providers with specialized contact center software offerings. Our actual and potential competitors may enjoy competitive advantages over us, including greater name recognition, longer operating histories, and larger marketing budgets, as well as greater financial or technical resources. With the introduction of new technologies and market entrants, we expect competition to intensify in the future.
In connection with our emphasis on the international long distance market for consumer customers, we face competition from low-cost international calling cards, digital calling cards and VoIP providers in addition to traditional telephone companies, cable companies, and wireless companies. To the extent that these providers target marketing to the same ethnic segments that we target or strengthen their offerings to these segments, we may have to reduce our prices or increase promotions, which would impair our profitability, or offer additional features that may cause us to incur additional costs without commensurate price increase.
As a result of increasing competition, domestic and international telephony and messaging rates have generally decreased during the past few years, and we expect this trend to continue. Continued rate pressures or increasing cost to use our services could lessen or eliminate the pricing advantage that we maintain over certain competitors and cause customers or potential customers to select alternative providers or cause us to lower our prices, which would adversely impact our revenues and profitability.

10     VONAGE ANNUAL REPORT 2018



As the cloud communications services market evolves, and the convergence of voice, video, messaging, mobility and data networking technologies accelerates, we may face competition in the future from companies that do not currently compete in the cloud communications services market, including companies that currently compete in other sectors, companies that serve consumer rather than business customers, or companies which expand their market presence to include business communications.market.
As the cloud communications services market evolves, combining voice, video, messaging and data networks, and information technology and communication applications, opportunity is created for new competitors to enter the cloud communications services market and offer competing products.products, including companies that currently compete in other sectors, companies that serve consumer rather than business customers, or companies which expand their market presence to include business communications. This new competition may take many forms, and may offer products and applications similar to ours. If these new competitors emerge, the cloud communications services market will become increasingly competitive and we may not be able to maintain or improve our market position. Our failure to do so could materially and adversely affect our business and results of operations.
We may face difficulties related to the acquisition or integration of businesses, which could harm our growth or operating results.
In August 2018, we acquired TokBox Inc. with the intention of integrating and adding video to our Business offerings in voice, SMS, and IP messaging. In October 2018, we completed the acquisition of NewVoiceMedia as a CCaaS provider, with the intention of combining our UCaaS and CPaaS solutions to provide an end-to-end communications experience for a company's employees and customers. In addition, we have made several acquisitions over the past several years to build our business services and continue to periodically review acquisition opportunities.
Acquisition and integration activities require substantial management time and resources. Acquisitions of existing businesses involve substantial risks, including the risk that we may not be able to integrate the operations, personnel, services, or technologies, the potential disruption of our ongoing businesses, the diversion of management attention, the maximization of financial and strategic opportunities, the difficulty in developing or maintaining controls and procedures, and the dilution to our existing stockholders from the issuance of additional shares of common stock. We may elect to acquire additional businesses or assets in the future. However, we cannot predict or guarantee that we will be able to identify suitable acquisition candidates or consummate any acquisition. As a result of these and other risks, we may not produce anticipated revenue, profitability, or synergies.
Acquisitions may require us to issue debt or equity securities, use our cash resources, incur debt or contingent liabilities, amortize intangibles, or write-off acquisition-related expenses. If we are unable to successfully integrate any acquired businesses or assets we may not receive the intended benefits of such acquisition. In addition, we cannot predict market reactions to any acquisitions we may make or to any failure to announce any future acquisitions.
Further, while we conduct due diligence in connection with acquisition and joint venture opportunities, there may be risks or liabilities that such due diligence efforts fail to discover, are not disclosed to us, or that we inadequately assess. The discovery of material liabilities associated with acquisitions or joint venture opportunities, economic risks faced by joint venture partners, or any failure of joint venture partners to perform their obligations could adversely affect our business, results of operations, and financial condition.
If we fail to adapt to rapid changes in the market for cloud communications services, then our products and services could become obsolete.
The market for our products and services is constantly and rapidly evolving as we and our competitors introduce new and enhanced products and services and react to changes in the cloud communications services industry and customer demands. We may not be able to develop or acquire new products and plans or product and plan enhancements that compete effectively with present or emerging cloud communications services technologies or differentiate our products and plans based on functionality and performance. In addition, we may not be able to establish or maintain strategic alliances that will permit enhancement opportunities or innovative distribution methods for our products and plans.
To address these issues, we are targeting revenue growth in large, existing markets, which require us to enhance our current products and plans, and develop new products and plans on a timely basis to keep pace with market needs and satisfy the increasingly sophisticated requirements of customers. If we are unable to attract users of these services our net revenues may fail to grow as we expect.

Cloud communications services are complex, and new products and plans and enhancements to existing products and plans can require long development and testing periods. Any delays in developing and releasing new or enhanced products and plans could cause us to lose revenue opportunities and customers. Any technical flaws in products we release could diminish the innovative impact of the products and have a negative effect on customer adoption and our reputation.

11     VONAGE ANNUAL REPORT 2018



We also are subject to the risk of future disruptive technologies. New products based on new technologies or new industry standards could render our existing products obsolete and unmarketable. If new technologies develop that are able to deliver competing voice and messaging services at lower prices, better or more conveniently, it could have a material adverse effect on us.
The market for our CPaaS products and platform is relatively nascent and may not experience the growth that we anticipate.
The utilization of application program interfaces (“APIs”) for text messaging and voice communications, allowing developers and businessesAPIs to embed contextual, programmable real time communications into mobile apps, websites and business systems workflows, remains a relatively new market, and developers and organizations may not yet recognize the need for, or benefits of, our products and platform. It is important that we are able to educate developers, organizational leaders, and other potential customers regarding our products and platform in order to help grow the market and to realize our market share, Theshare. If we fail to achieve the foregoing, the market for our products and platform or our share of that market could fail to grow significantly. If the CPaaS market, or our share of that market, does not experience significant growth, then our business, results of operations and financial condition could be adversely affected.
If we are unsuccessful at retaining customers or attracting new consumer or business customers we may experience a reduction in revenue or may be required to spend more money or alter our marketing approaches to grow our customer base.
Our rate of customer terminations for our UCaaS services could increase in the future if customers are not satisfied with the quality and reliability of our network, the value proposition of our products, and the ability of our customer service to meet the needs and expectations of our customers. We measure customer terminations for our consumer customers by average monthly customer churn and for our UCaaS business customers by average monthly revenue churn. Competition from traditional telephone companies, cable companies, wireless companies, alternative communications providers, low-cost international calling cards, disruptive technologies, general economic conditions, and our ability to activate and register new customers on our networks, also influence our churn rate. For our CPaaS and CCaaS customers, our ability to grow revenue depends, in part, on our ability to maintain and grow usage of our platform by new and existing customers. If we are not able to increase customer usage of our products, our revenue may decline which would adversely impact our business, results of operations and financial condition. Our CPaaS customers are charged based on their usage of our products and generally our customers do not have long-term contractual financial commitments to us, therefore, usage rates may fluctuate at any time. A material decline in the usage of our products could cause us to spend significantly more on sales and marketing than we currently budget in order to maintain or increase revenue from customers, which could adversely affect our business, results of operations and financial condition. In addition, our agreements with business customers typically provide for service level commitments. If we are unable to meet these commitments or if we suffer extended periods of downtime for our products or platform, our business, results of operations and financial condition could be adversely affected. Our ability to attract and retain customers for our consumer services are impacted by our pricing, brand awareness, customer service, network and system reliability and service features and capabilities. Competition from traditional telephone companies, cable companies, wireless companies, alternative communication providers, low-cost international calling cards, disruptive technologies, general economic conditions, and our ability to activated and register new customers on our network also influence churn rate. A material decline in the usage of our business and consumer products could cause us to spend significantly more on sales and marketing than we currently budget in order to maintain or increase revenue from customers, which could adversely affect our business, results of operations and financial condition.
The success of our CPaaS products depends in part on attracting new customers in a cost-effective manner. The failure to do so could materially and adversely affect our business.
The success of our business relies on our ability to attract new customers in part on thea cost effective manner in which we use, and the cost effectiveness of,by using a variety of marketing channels used to promote our products and platform and attract new customers.channels. We use developer events and developer evangelism, search engine marketing and optimization, and other marketing efforts such as
regional customer events, email campaigns, advertising and public relations events. These methods are prioritized depending on effectiveness and efficiency, and may be altered if costs increase dramatically.dramatically or if the results do not meet expectations. Alternative, less expensive channels, may not be as effective as our preferred channels. Our continued success requires that we continue to attract new customers in a cost-effective manner. If we fail to do so, our revenues may decrease and our operating results would suffer.
Our success in the cloud communications market for our business services depends in part on developing and maintaining effective distribution channels, including our internal direct sales team, third-party resellers, and value-added distributors.channels. The failure to develop and maintain these channels could materially and adversely affect our business.
A portion of our business revenue is generated through our direct sales, or “field sales,” team. This channel consists of sales agents that market and sell our business services products to customers to customers through direct, commonly face-to-face interaction. This channel may generate an increasing portion of our business revenue in the future. Our continued success requires that we continue developing and maintaining a successful sales organization. If we fail to do so, or if our sales agents are not successful in their sales efforts, our sales may decrease and our operating results would suffer.

12     VONAGE ANNUAL REPORT 2018



A portion of our business revenue is generated through indirect channel sales. These channels consist of third-party resellers and value-added distributors that market and sell our business services products to customers. These channels may generate an increasing portion of our business revenue in the future. Generally, we do not have long-term contracts with these third-party resellers and value-added distributors, and the loss of or reduction in sales through these third parties could materially reduce our revenues. We also compete for preference amongst our current or potential resellers with our competitors. Our continued success requires that we continue developing and maintaining successful relationships with these third-party resellers and value-added distributors. If we fail to do so, or if our resellers are not successful in their sales efforts, our sales may decrease and our operating results would suffer.
We may face difficulties related to the acquisition or integration of businesses, which could harm our growth or operating results.
Beginning with our acquisition of Vocalocity in 2013, we have made a number of acquisitions related to the UCaaS market, including Telesphere Networks, Ltd. in 2014, Simple Signal, Inc. and iCore Networks, Inc. in 2015 and Nexmo Inc., in 2016. However, acquisition and integration activities require substantial management time and resources. Acquisitions of existing businesses, including Nexmo, involve substantial risks, including the risk that we may not be able to integrate the operations, personnel, services, or technologies, the potential disruption of our ongoing businesses, the diversion of management attention, the maximization of financial and strategic opportunities, the difficulty in developing or maintaining controls and procedures, and the dilution to our existing stockholders from the issuance of additional shares of common stock. We may elect to acquire additional businesses or assets in the future. However, we cannot predict or guarantee that we will be able to identify suitable acquisition candidates or consummate any acquisition. As a result of these and other risks, we may not produce anticipated revenue, profitability, or synergies.
Acquisitions may require us to issue equity securities, use our cash resources, incur debt or contingent liabilities, amortize intangibles, or write-off acquisition-related expenses. If we are unable to successfully integrate any acquired businesses or assets we may not receive the intended benefits of such acquisition. In addition, we cannot predict market reactions to any acquisitions we may make or to any failure to announce any future acquisitions.
Further, while we conduct due diligence in connection with acquisition and joint venture opportunities, there may be risks or liabilities that such due diligence efforts fail to discover, are not disclosed to us, or that we inadequately assess. The discovery of material liabilities associated with acquisitions or joint venture opportunities, economic

risks faced by joint venture partners, or any failure of joint venture partners to perform their obligations could adversely affect our business, results of operations, and financial condition.
Security breaches and other cybersecurity or technological risks could compromise our information systems and network and expose us to liability, which wouldcould cause our business and reputation to suffer and which could have a material adverse effect on our business, financial condition, and operating results.
There are several inherent risks to engaging in a technology business, including our reliance on our data centers and networks, and the use and interconnectivity of those networks. A significant portion of our operations relies heavily on our ability to provide secure processing, storage and transmission of confidential and other sensitive data, including intellectual property, proprietary business information, and personally identifiable information of our customers and employees, in our data centers and on our networks. The secure processing, storage, and transmission of this information is critical to our operations and business strategy. As seen in our industry and others, these activities have been, and will continue to be, subject to continually evolving cybersecurity or other technological risks. Targeted attacks, such as advanced persistent threat (APT) is prevalent throughout the Internet and associated with the theft of intellectual property and state-sponsored espionage. Due to the nature of our business and reliance on the Internet, we are susceptible to this type of attack. In addition, physical security of devices located within our offices, and/or remote devices, pose cybersecurity and other technological risks that could negatively impact our business and reputation.
We also operate Internet based, worldwide data, voice, video communications, and messaging services and electronic billing, which require the transmission of confidential and at times personal or sensitive customer or employee information over public networks that may or may not support end to end security. Despite our security measures, which include the development, operation and maintenance of systems and processes that are designed to protect consumer and employee information and prevent fraudulent credit card transactions and other security breaches, our information technology and infrastructure may be vulnerable to attacks by hackers or breached due to error, malfeasance or other disruptions by a current or former employee or third-party provider and our failure to mitigate such fraud or breaches may adversely affect our operating results. Any such breach could compromise our systems and network and the information stored there could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, regulatory penalties, disruption to our operations, damage to our reputation, and a loss of confidence in our products and services, and our ability to keep personally identifiable information confidential, which could adversely affect our business.
We have been subject to cybercybersecurity incidents from external sources including “brute force” and distributed denial of service attacks, as well as attacks that introduce fraudulent VoiPVoIP traffic. Although these incidents have not had a material adverse effect financially or on our ability to provide services, this may not continue to be the case going forward. There can be no assurance that cybercybersecurity incidents will not occur in the future, potentially more frequently and/or on a more significant scale.
We have taken steps designed to improve the security of our networks and computer systems and our physical space. Despite these defensive measures, thereThere can be no assurance that we are adequately protecting our information or that we will not experience future incidents. The expenses associated with protecting our information could reduce our operating margins. We maintain insurance intended to cover some of these risks, however, this insurance may not be sufficient to cover all of our losses from any future breaches of our systems. In addition, third parties with which we do business may also be sources of cybersecurity or other technological risks. We outsource certain functions, which results in the storage and processing of customer information by third parties. While we engage in certain actions to reduce the exposure resulting from outsourcing, unauthorized access, loss or destruction of data or other cybercybersecurity incidents could occur, resulting in similar costs and consequences as those discussed above.
We make available on our website our privacy policy, which describes how we collect, use, and disclose our customers' personal information. To the extent we expand our operations into new geographies, we may become subject to local data security, privacy, data retention, and disclosure laws and regulations. It may be difficult for us to comply with these laws and regulations if they were deemed to be applicable to us. In addition, risks related to cybercrime and fraud increase when establishing a global presence.

13     VONAGE ANNUAL REPORT 2018



We are subject to Payment Card Industry, (“PCI”)or PCI, data security standards, which require periodic audits by independent third parties to assess compliance. PCI data security standards are a comprehensive set of requirements for enhancing payment account data security that was developed by the PCI Security Standards Council including American Express, Discover Financial Services, JCB International, MasterCard Worldwide, and VISA Inc., to help facilitate the broad adoption of consistent data security measures. Failure to comply with the security requirements as identified in subsequent audits or rectify a security issue may result in fines. While we believe it is unusual, restrictions on accepting payment cards, including a complete restriction, may be imposed on companies that are not compliant. Further, the law relating to the liability of providers of online payment services is currently unsettled and states may enact their own rules with which we may not comply.
We rely on third partythird-party providers to process and guarantee payments made by Vonage and its affiliates’ subscribers, up to certain limits, and we may be unable to prevent our customers from fraudulently receiving goods and services. Our liability risk will increase if a larger fraction of our Vonage transactions involve fraudulent or disputed credit card transactions. Any costs we incur as a result of fraudulent or disputed transactions could harm our business. In addition, the functionality of our current billing system relies on certain third party vendors delivering services. If these vendors are unable or unwilling to provide services, we will not be able to charge for our services in a timely or scalable fashion, which could significantly decrease our revenue and have a material adverse effect on our business, financial condition and operating results.
Sales of our business services to medium-sized and enterprise customers involve significant risks which, if not managed effectively, could materially and adversely affect our business and results of operations.
As we continue to expand our sales efforts to medium-sized and larger businesses, we may incur higher selling expense and longer, more complex, sales cycles. Customers in this market segment may also require bespoke features and integration services, increasing the complexity and expense related to the sales and delivery process. As a result, we may devote greater sales and support to these customers, which may result in increased costs and a strain on our support resources. These factors could materially and adversely affect our results of operations and our overall ability to grow our customer base.
Our ability to provide our telephony service and manage related customer accounts is dependent upon third-party facilities, equipment, and systems, the failure of which could cause delays of or interruptions to our service, damage our reputation, cause us to lose customers, limit our growth, and affect our financial condition.
Our success depends on our ability to provide quality and reliable telephony service, which is in part dependent upon the proper functioning of facilities and equipment owned and operated by third parties and is, therefore, beyond our control. Unlike traditional wireline telephone service or wireless service, our telephony service typically requires our customers to have an operative broadband Internet connection and an electrical power supply, which are provided by the customer's Internet service provider and electric utility company, respectively, and not by us. The quality of some broadband Internet connections may be too poor for customers to use our telephony services properly. In addition, if there is any interruption to a customer's broadband Internet service or electrical power supply, that customer will be unable to make or receive calls, including emergency calls, using our telephony service.

We outsource several of our network functions to third-party providers. For example, we outsource the maintenance of our regional data connection points, which are the facilities at which our network interconnects with the public switched telephone network. If our third-party service providers fail to maintain these facilities properly, or fail to respond quickly to problems, our customers may experience service interruptions. Interruptions in our service caused by third-party facilities have in the past caused and may in the future cause us to lose customers or cause us to offer substantial customer credits, which could adversely affect our revenue and profitability. If interruptions adversely affect the perceived reliability of our service, we may have difficulty attracting new customers, and our brand, reputation, and growth will be negatively impacted.
In order to access our consumer services, a customer needs to connect a standard telephone to a broadband Internet connection through a Vonage-enabled device that we provide. Although we closely monitor inventory levels, if we are unable to procure a sufficient number of devices from our suppliers in a timely manner, including as a result of a failure by a component supplier, we would be delayed in activating new customers and may lose these customers.
While we believe that relations with our current third party providers are good, and we have contracts in place with these vendors, thereThere can be no guarantee that these third party providers will be able or willing to supply services to us in the future on commercially reasonable terms, or that we will be able to engage alternative or additional providers. We believe that we could replace our current third party providers, however, ourOur ability to provide our services may be impacted during any transition, which could have an adverse effect on our business, financial condition or results of operations.
We rely on third-party vendors that may be difficult to replace or may not perform adequately.
For our CPaaS customers, we rely on IBM Softlayer to provide substantially all of the cloud infrastructure that hosts our CPaaS products and platform. Our CPaaS customers require uninterrupted performance of this platform and we are therefore vulnerable to service interruptions at Softlayer.third-party data center providers, such as IBM Softlayer and Amazon Web Services, or AWS. We may experience interruptions, delays and outages in Softlayer’sthird-party service and availability due to a variety of factors, including infrastructure changes, human or software errors, website hosting disruptions and capacity constraints caused by technical failures, natural disasters, fraud or security attacks. To the extent that we do not effectively address interruptions, delays and outages in Softlayer’s service and availability or capacity constraints, our business, results of operations and financial condition may be adversely affected.

14     VONAGE ANNUAL REPORT 2018



In some cases we rely on purchased or leased hardware and software licensed from third parties in order to provide our UCaaS services. For example, Broadsoft, Inc. provides us with infrastructure, call termination and origination services, and other hardware and software in connection with our PremierVonage Enterprise offerings. We also integrate third-party licensed software components into our platform. This hardware and software may not continue to be available on commercially reasonable terms or pricing or may fail to continue to be updated to remain competitive. The loss of the right to use this third party hardware or software may increase our expenses or impact the provisioning of our services. The failure of this third party hardware or software could materially impact the performance of our UCaaS services and may cause material harm to our business or results of operations.
We outsource some of our cloud infrastructure to Amazon Web Services, or AWS which hosts certain of our products and platform. Customers of our products need to be able to access our platform at any time, without interruption or degradation of performance. AWS runs its own platform that we access, and we are, therefore, vulnerable to service interruptions at AWS. To the extent that we do not effectively address capacity constraints, either through AWS or alternative providers of cloud infrastructure, our business, results of operations and financial condition may be adversely affected. In addition, any changes in service levels from AWS may adversely affect our ability to meet our customers’ requirements.
Flaws in our technology and systems or our failure to adapt our systems to any new Internet Protocol could cause delays or
interruptions of service, which could damage our reputation, cause us to lose customers, and limit our growth.
Although we have designed our service network to reduce the possibility of disruptions or other outages, ourOur service may be disrupted by problems with our technology and systems such as malfunctions in our Vonage-enabled device that we provide to customers, software or facilities and overloading of our network. As we attract new subscribers,customers, we expect increased call volume that we need to manage to avoid network interruptions. In particular, as we have marketed to different international long distance markets, we have seen international call volumes to targeted countries increase. During the next few years we expect wide-spread industry adoption of a new Internet Protocol, which is a set of standard communications and routing mechanisms. Customers may experience periodic delays of service caused by the industry transition to this new Internet Protocol. Interruptions have caused and may in the future cause us to lose customers and offer substantial customer credits, which could adversely affect our revenue and profitability. Network interruptions have also impaired our ability at times to sign-up new customers and the ability of customers to manage their accounts. If service interruptions or other outages adversely affect the perceived reliability of our telephony service or customer service, we may have difficulty attracting and retaining customers and our brand reputation and growth may suffer.
In addition, we utilize third-party Internet-based or “cloud” computing services in connection with some of our business operations. Any disruption to the internetInternet or to our third-party Web hosting or cloud computing providers, including technological or business-related disruptions, could adversely impact the experience of our customers and have adverse effects on our operations. In addition, fires, floods, earthquakes, power losses, telecommunications failures, and similar "Acts of God" could damage these systems and hardware or cause them to fail completely. While we do maintain redundant systems consistent with industry best practices including standby data centers, certain events could result in downtime for our operations and could adversely affect our business.
The storage, processing, and use of personal information and related data subjects us to evolving governmental laws and regulation, commercial standards, contractual obligations, and other legal obligations related to consumer and data privacy, which may have a material impact on our costs, use of our products and services, or expose us to increased liability.
Federal, state, local and foreign laws and regulations, commercial obligations and industry standards, each provide for obligations and restrictions with respect to data privacy and security, as well as the collection, storage, retention, use, processing, transmission, sharing, disclosure and protection of personal information and other customer data. The evolving nature of these obligations and restrictions dictates that differing interpretations, inconsistency or conflicts among countries or rules, and general uncertainty impact the application to our business.
These obligations and restrictions may limit our ability to collect, store, process, use, transmit and share data with our customers, employees, and third party providers, which in turn could limit the ability of our customers to collect, store, retain, protect, use, process, transmit, share and disclose data with others through our products and services. Compliance with, and other burdens imposed by, such obligations and restrictions could increase the cost of our operations and impact our ability to market our products and services through effective segmentation.
An example of data privacy and security obligations and restrictions include the European Union General Data Protection Regulation, GDPR. The GDPR was adopted in April 2016 and comprehensively regulates the processing of personal data of any individual residing in the EU. The GDPR effectively requires any company processing data of EU individuals to develop a comprehensive privacy program. The GDPR becomes effective on May 25, 2018. In addition, in January 2017, the European Commission introduced a new proposed ePrivacy regulation that would restrict communications service provider’s ability to use metadata and content from communications services. In order to become effective, the proposal needs to be adopted by the European Council and European Parliament. In October 2016, the Federal Communications Commission adopted a new privacy rules for the U.S. communications industry. These rules greatly extended the scope of FCC privacy regulation. Numerous parties have filed petitions for reconsideration at the FCC on the new privacy rules.

15     VONAGE ANNUAL REPORT 2018



Failure to comply with obligations and restrictions related to applicable data protection laws, regulations, standards, and codes of conduct, as well as our own posted privacy policies and contractual commitments could subject us to lawsuits, fines, criminal penalties, statutory damages, consent decrees, injunctions, adverse publicity, loss of user confidence in our services, and loss of users, which could materially harm our business. Additionally, third-party contractors may have access to customer or employee data. If these or other third-party vendors violate obligations and restrictions related to applicable data protection laws or our policies, such violations may also put our customers’ or employees’ information at risk and could in turn have a material and adverse effect on our business.
Our Business segment is growing rapidly, and any inability to scale our business and grow efficiently could materially and adversely harm our business and results of operations.
As our Business segment expands, we will need to continue to improve our application architecture, integrate our products and applications across our technology platforms, integrate with third-party systems, and maintain infrastructure performance. We expect the number of users, the amount of data transferred and processed, the number of locations where our service is being used, and the volume of communications over our networks to continue to expand. To address this growth, we will need to scale our systems and customer services organization. Our ability to execute on these initiatives may impact system and network performance, customer satisfaction, and ultimately, sales and revenue. These efforts may also divert management resources. These factors may materially and adversely harm our business and results of operations.
We depend on third partythird-party vendors to supply, configure and deliver the phones that we sell. Any delays in delivery, or failure to operate effectively with our own servers and systems, may result in delay or failure of our services, which could harm our business, financial condition and results of operations.
We rely on Yealink Inc. and Polycom, Inc. to provide, and a single fulfillment agent to configure and deliver, the phones that we offer for sale to our customers that use our UCaaS services. If these third parties are unable to deliver phones of acceptable quality or quantity, or in a timely manner, we may be forced to offer replacements at a higher cost than what is currently contracted. In addition, these phones must interoperate with our servers and systems. If either of our providers changes the operation of their phones, we may be required to engage in development efforts to ensure that the new phones interoperate with our system. The failure of our vendor-supplied phones to operate effectively with our system could impact our customers’ ability to use our services and could cause customers to cancel our services, which may cause material harm to our business or results of operations.

We market our products and services to small and medium-sized businesses, which may be disproportionately impacted by fluctuations in economic conditions.
We market our products to small and medium-sized businesses. Customers in this market may be affected by economic downturns to a greater extent, and may have more limited financial resources, than larger or more established businesses. If customers in our Business markets experience financial hardship as a result of a weak economy, the demand for our services could be materially and adversely affected.
The storage, processing,Significant foreign currency exchange rate fluctuations could adversely affect our financial results.
Because our consolidated financial statements are presented in U.S. dollars, increases or decreases in the value of the U.S. dollar relative to other currencies in which we transact business could materially adversely affect our financial results. For example, Nexmo collects revenues in Euros, and useaccordingly the strengthening of personal informationthe U.S. dollar relative to the Euro adversely affects our revenue and related data subjects us to evolving governmental laws and regulation, commercial standards, contractual obligations, and other legal obligations related to consumer and data privacy,operating results presented in U.S. dollars. In addition, on June 23, 2016, the United Kingdom held a referendum in which may have a material impact on our costs, usemajority of our products and services, or expose us to increased liability.
Federal, state, local and foreign laws and regulations, commercial obligations and industry standards, each provide for obligations and restrictions with respect to data privacy and security, as well as the collection, storage, retention, protection, use, processing, transmission, sharing, disclosure and protection of personal information and other customer data. The evolving nature of these obligations and restrictions dictates that differing interpretations, inconsistency or conflicts among countries or rules, and general uncertainty impact the application to our business.
These obligations and restrictions may limit our ability to collect, store, process, use, transmit and share data with our customers, employees, and third party providers and to allow our customers to collect, store, retain, protect, use, process, transmit, share and disclose data with others through our products and services. Compliance with, and other burdens imposed by, such obligations and restrictions could increase the cost of our operations and impact our ability to market our products and services through effective segmentation.

Failure to comply with obligations and restrictions related to applicable data protection laws, regulations, standards, and codes of conduct, as well as our own posted privacy policies and contractual commitments could subject us to lawsuits, fines, criminal penalties, statutory damages, consent decrees, injunctions, adverse publicity, loss of user confidence in our services, and loss of users, which could materially harm our business. Additionally, third-party contractors may have access to customer or employee data. If these or other third-party vendors violate obligations and restrictions related to applicable data protection laws or our policies, such violations may also put our customers’ or employees’ information at risk and could in turn have a material and adverse effect on our business.

If we fail to protect unique aspects of our internally developed systems, technology, products, and software and our trademarks, we may become involved in costly litigation or our business or brand may be harmed.
Our ability to compete effectively is dependent in large part upon the maintenance and protection of systems and software that we have developed internally based on open standards. While we own over 150200 issued U.S. patents (andas well as a number of foreign patents)patents and more
than 170over 40 pending U.S. patent applications (andalong with a number of foreign patent applications),applications, we cannot patent much of the technology that is important to our business. Our pending patent applications may not be granted. Any issued patent that we own may be challenged, narrowed, invalidated, or circumvented. To date, we have relied on patent, copyright and trade secret laws, as well as confidentiality procedures and licensing arrangements, to establish and protect our rights to this technology. We typically enter into confidentiality agreements with our employees, consultants, customers, partners, and vendors in an effort to control access to and distribution of technology, software, documentation, and other information. Despite these precautions, it may be possible for a third party to copy or otherwise obtain and use this technology without authorization. Policing unauthorized use of this technology is difficult. The steps we take may not prevent misappropriation of the technology we rely on. In addition, effective protection may be unavailable or limited in some jurisdictions outside the United States, Canada, and the United Kingdom. Litigation may be necessary in the future to enforce or protect our rights or to determine the validity and scope of the rights of others. That litigation could cause us to incur substantial costs and divert resources away from our daily business, which in turn could materially adversely affect our business.
The unlicensed use of our brands by third parties could harm our reputation, cause confusion among our customers, and impair our ability to market our services. To that end, we have registered numerous trademarks and service marks and have applied for registration of our trademarks and service marks in the United States and abroad to establish and protect our brand names as part of our intellectual property strategy. If our applications receive objections or are successfully opposed by third parties, it may be difficult for us to prevent third parties from using our brand without our permission. Moreover, successful opposition to our applications might encourage third parties to make additional oppositions or commence trademark infringement proceedings against us, which could be costly and time consuming to defend against. If we decide to take limited or no action to protect our trademarks, our trademark rights may be diluted and subject to challenge or invalidation, which could materially and adversely affect our brand in the marketplace.
Third parties may be capable of fraudulently useusing our name to obtain access to customer accounts and other personal information, use our services to commit fraud or steal our services or equipment, which could damage our reputation, limit our growth, and cause us to incur additional expenses.
Our customers have been subject to “phishing,” which occurs when a third party calls or sends an email or pop-up message to a customer that claims to be from a business or organization that provides services to the customer. The purpose of the inquiry is typically to encourage the customer to visit a bogus website designed to look like a website operated by the legitimate business or organization or provide information to the operator. At the bogus website, the operator attempts to trick the customer into divulging customer account or other personal information such as credit card information or to introduce viruses through “Trojan horse” programs to the customers’ computers. This has resulted in identity theft from our customers and the unauthorized use of Vonage services. Third parties have also used our communications services to commit fraud. Although we have engaged a third party to assist in the shutdown of purported phishing sites, if we are unable to detect and prevent “phishing,” use of our services for fraud, and similar activities, our brand reputation and growth may suffer and we may incur additional costs, including costs to increase security, or be required to credit significant amounts to customers.
Third parties also have used our communications services and obtained delivery of our equipment without paying, including by submitting fraudulent credit card information. This has resulted in our incurring the cost of providing the services, including incurring call termination fees, or providing the equipment without any corresponding revenues. We have implemented anti-fraud procedures in order to limit the expenses resulting from theft of service or equipment. If our procedures are not effective, theft of service or equipment could significantly increase our expenses and negatively impact our profitability.
The debt agreements governing our financing contain restrictions that may limit our flexibility in operating our business or executing on our acquisition strategy.
On July 31, 2018, we replaced our 2016 Credit Facility previously consisting of a $125 million senior secured 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 facility. The 2018 Credit Facility contains customary representations and warranties and affirmative covenants that limit our ability and/or the ability of certain of our subsidiaries to engage in specified types of transactions. These covenants and other restrictions may under certain circumstances limit, but not necessarily preclude, our and certain of our subsidiaries’ ability to, among other things:

consolidate or merge;
create liens;
incur additional indebtedness;

1317     VONAGE ANNUAL REPORT 20162018



dispose of assets;
consummate acquisitions;
Certain rightsmake investments; or
pay dividends and other distributions.

Under the 2018 Credit Facility, we are required to third party patentscomply with financial covenants, including the following financial covenants:
specified maximum consolidated leverage ratio;
specified minimum consolidated fixed coverage charge ratio, minimum cash position and technologymaximum capital expenditures.

Our ability to comply with such financial and other covenants may not be available, which may decrease the quality ofaffected by events beyond our products or services or subject us to liability.
We may seek to obtain rights to third party technology in the future, butcontrol, so we may not be able to agree upon commercially reasonablecomply with these covenants. A breach of any such covenant could result in a default under the 2018 Credit Facility. In that case, the lenders could elect to declare due and payable immediately all amounts due under the 2018 Credit Facility, including principal and accrued interest.
If we require additional capital, we may not be able to obtain additional financing on favorable terms or at all with respectall.
We may need to obtainingpursue additional financing to respond to new competitive pressures, pay extraordinary expenses such rights. Ifas litigation settlements or judgments or fund growth, including through acquisitions. Because of our past significant losses and our limited tangible assets, we are unable to extend existing licenses or are unabledo not fit traditional credit lending criteria, which, in particular, could make it difficult for us to obtain rightsloans or to other technology that may be commercially advantageous or necessaryaccess the capital markets. In addition, the credit documentation for our productrecent financing contains affirmative and service offerings, wenegative covenants that affect, and in many respects may experience a decrease in the qualitysignificantly limit or prohibit, among other things, our and certain of our productssubsidiaries’ ability to incur, refinance or services or we may losemodify indebtedness and create liens. Our credit card processors have the ability to provideimpose significant holdbacks in certain circumstances. The reinstatement of such holdbacks likely would have a material adverse effect on our productsliquidity. Under our credit card processing agreements with our Visa, MasterCard, American Express, and services onDiscover credit card processors, the credit card processor has the right, in certain circumstances, including adverse events affecting our business, to impose a non-infringing basis until alternative technologyholdback of our advanced payments purchased using a Visa, MasterCard, American Express, or suitable alternative products and services can be developed, identified, obtained (through acquisition, licenseDiscover credit card, as applicable, or demand additional reserves or other grantssecurity. If circumstances were to occur that would allow any of rights),these processors to reinstate a holdback, the negative impact on our liquidity likely would be significant. In addition, our Visa and integrated.MasterCard credit card processing agreement may be terminated by the credit card processor at its discretion if we are deemed to be financially insecure. As a significant portion of payments to us are made through Visa and MasterCard credit cards, if the credit card processor does not assist in transitioning our business to another credit card processor, the negative impact on our liquidity likely would be significant. There were no cash reserves and cash-collateralized letters of credit with any credit card processors as of December 31, 2018.
We may be subject to damaging and disruptive intellectual property litigationdisputes that could materially and adversely affect our business, results of operations, and financial condition, as well as the continued viability of our company.
There has been substantial litigation in the cloud communications, UCaaS, VoIP, telecommunications, hosted services, and related industries regarding intellectual property rights and, given the rapid technological change in our industry, expansion into new technological and geographical markets, and our continual development of new products and services, we and/or our commercial partners may be subject to infringement claims from time to time.  For example, we may be unaware of filed patent applications and issued patents that could include claims that might be interpreted to cover our products and services.  We have been subject to patent infringement claims in the past, are currently named as a defendant in several proceedings that relate to alleged patent infringement, and from time to time we receive letters from third parties offering an opportunity for us to obtain licenses to patents that may be relevant to our business or alleging that our services infringe upon third party patents or other intellectual property. See “Item 3. - Legal Proceedings-IP Matters.”We may seek to obtain rights to third party technology in the future, but may not be able to agree upon commercially reasonable terms or at all with respect to obtaining such rights. If we are unable to extend existing licenses or are unable to obtain rights to other technology that may be commercially advantageous or necessary for our product and service offerings, we may experience a decrease in the quality of our products or services or we may lose the ability to provide our products and services on a non-infringing basis until alternative technology or suitable alternative products and services can be developed, identified, obtained either through acquisition, license or other grants of rights, and integrated.
Parties making claims of infringement may be able to obtain injunctive or other equitable relief that could effectively block our ability to provide our services and could cause us to pay substantial royalties, licensing fees, damages or settlement fees. Our agreements with certain customers, vendors, or partners may obligate us to defend or indemnify them in connection with such claims of infringement, further increasing our costs of defense and potential liability. Although we generally limit our contractual liability regarding such obligations, we may incur significant liability with respect to them, and disputes with our customers, vendors or partners over such obligations may have an adverse relationship on our relations with those entities. The defense of

18     VONAGE ANNUAL REPORT 2018



any lawsuit could divert management’s efforts and attention from ordinary business operations and result in time-consuming and expensive litigation, regardless of the merits of such claims. These outcomes may:

>
result in the loss of a substantial number of existing customers or prohibit the acquisition of new customers;

>cause us to accelerate expenditures to preserve existing revenues;

>cause existing or new vendors to require prepayments or letters of credit;

>cause our credit card processors to demand reserves or letters of credit or make holdbacks;

require us to cease certain business operations or offering certain products and services; and
lead to our bankruptcy or liquidation.

We rely on third parties to provide a portion of our customer service representatives, provide aspects of our E-911 service, which differs from traditional 911 service, and initiate local number portability for our customers. If these third parties do not provide our customers with reliable, high-quality service, our reputation will be harmed and we may lose customers.
We offer our customers support 24 hours a day, seven days a week through both our comprehensive online account management website and our toll free number. Our customer support is currently provided via United States based employees as well as third party partners located in the United States, Philippines, Costa Rica, Chile,Czechoslovakia, Mexico, Poland and India. We can offer support in English, Spanish, and French Canadian. Our third-party providers generally represent us without identifying themselves as independent parties. The ability to support our customers may be disrupted by natural disasters, inclement weather conditions, civil unrest, and other adverse events in the locations where our customer support is provided.
We also contract for services required to provide E-911 services including assistance in routing emergency calls, terminating E-911 calls, operating a national call center that is available 24 hours a day, seven days a week to receive certain emergency calls, and maintaining PSAP databases for the purpose of deploying and operating E-911 services. Interruptions in service from our vendor could cause failures in our customers’ access to E-911 services and expose us to liability and damage our reputation.
We also have agreements with companies that initiate our local number portability, which allow new customers to retain their existing telephone numbers when subscribing to our services.
If any of these third parties do not provide reliable, high-quality service, our reputation and our business will be harmed. In addition, industry consolidation among providers of services to us may impact our ability to obtain these services or increase our expense for these services.
Our services are subject to regulation in the United States, United Kingdom, and Canada, and futurein additional countries as we expand globally. Future legislative, regulatory or judicial actions could adversely affect our business and expose us to liability.liability and limit our growth potential.
Our business has developed in a relatively lightly regulated environment. However, the United States, United Kingdom, and Canada have applied some traditional telephone company regulations to VoIP and continue to evaluate how VoIP should be regulated.regulated, as are other countries as we expand globally. The effects of future regulatory developments are uncertain. At the federal level in the U.S., the Federal Communications Commission (“FCC”) has imposed certain telecommunications regulations on VoIP services including:including, but not limited to:

>Requirements to provide E911
Requirements to provide E-911 service;
>Communications Assistance for Law Enforcement Act (“CALEA”) obligations;
>Obligation to support Universal Service;
>Customer Proprietary Network Information (“CPNI”) requirements;
>Disability access obligations;
>Local Number Portability requirements;
>Service discontinuance notification obligations;
>Outage reporting requirements; and
Communications Assistance for Law Enforcement Act obligations;
Obligation to support Universal Service;
Customer Proprietary Network Information, or CPNI, requirements;
Disability access obligations;
Local Number Portability requirements; and
Consumer protection, including protection from unwanted telemarketing and other calls.

As we expand globally, these types of regulations are likely to be similarly enacted and enforced by local regulatory authorities.


1419     VONAGE ANNUAL REPORT 20162018



>Rural call completion reporting and rules related to ring signal integrity.
In general, the focus of interconnected VoIP telecommunications regulation is at the federal level. On November 12, 2004, the FCC issued a declaratory ruling providing that our service is subject to federal regulation and preempted the Minnesota Public Utilities Commission from imposing certain of its regulations on us. While this ruling does not exempt us from all state oversight of our service, it effectively prevents state telecommunications regulators from imposing certain burdensome and inconsistent market entry requirements and certain other state utility rules and regulations on our service. As such,Despite this, Vonage ismay be subject to relatively few state and local regulatory requirements including:
>Payment of state and local E911 fees; and
>State Universal Service support obligations.

Payment of state and local E-911 fees; and
State Universal Service support obligations.

In Canada, the Canadian Radio-televisionRadio-Television and Telecommunications Commission, (“CRTC”)or CRTC, regulates VoIP service. CRTC VoIP regulations include:

>Local Number Portability requirements.
VOIP Service. In the UK, we are subject to regulation in the UK by the Office of Communications, (“OFCOM”).or OFCOM, VoIP regulations include:
>Requirement to provide 999/112 service; and
>Number Portability requirements.
regulates voice services. Other regulatory bodies in various jurisdictions regulate services Vonage seeksoffers its customers. These regulated services are similar to comply with all applicable regulatory requirements. We could, however, be subject to regulatory enforcement action if a regulator does not believe that we are complying with applicable regulations.
In addition,those regulated in the regulatory framework for VoIP service is still evolving and it is possible that Vonage could be subject to additional regulatory obligations and/or existing regulatory obligations could be modified or expanded. For instance, several states public utility commissions are attempting to regulate ‘fixed’ VoIP provided by cable companies. These states believe that the FCC’s 2004 Vonage Preemption Order did not preempt regulation of these ‘fixed’ services. The effects of future regulatory developments are uncertain.United States discussed above. Future legislative, judicial or other regulatory actions could have a negative effect on our business. If we become subject to the rules and regulations applicable to telecommunications providers in individual states or other foreign jurisdictions, we may incur significant litigation and compliance costs, and we may have to restructure our service offerings, exit certain markets, or raise the price of our services, any of which could cause our services to be less attractive to customers. In addition, future regulatory developments could increase our cost of doing business and limit our growth.
The regulatory framework for CPaaS services iscontinues to develop, as many existing regulations may not developed;fully contemplate this type of service or business model; future legislative, regulatory or judicial actions onimpacting CPaaS could adversely affect our business and financial results of operations, increase the cost and complexity of compliance, and expose us to liability.
In mostmany countries where we offer CPaaS products, it is not clear how CPaaS fits into the communications regulatory framework. Regulators could claim that our CPaaS products are subject to licensing and substantive communications regulatory requirements, or could modify their regulatory requirementsregulations to make it clear thatexplicitly expand the obligations to which CPaaS products are covered. For instance,subject, or could increase the proposed Electronic Communications Code released by the European Commission in October 2016, which if adopted by the European Councillevel of scrutiny and European Parliament would update the communications law framework in the EU, arguably subjects CPaaS services to many traditional telecommunications regulations.enforcement they apply.
Future legislative, judicial or other regulatory actions could have a negative effect on our business. If our CPaaS products become subject to theadditional rules and regulations applicable to technology or communications providers, we may incur significant litigation and compliance costs,costs. We may also experience interruptions or limitations on the delivery and weuse of our CPaaS products on our platform, or incur significant losses based on the timing of customer payments and any difficulty in collecting accounts receivable from CPaaS customers. Any decreased use of our products and services or limitation on our ability to collect payments from our customers could adversely affect our business, results of operations, and financial condition.
We may also have to restructure or discontinue certain of our service offerings, exit certain markets, or raise the price of our services in response to regulatory changes or actions, any of which could cause our services to be less attractive to customers. In addition, future regulatory developments could increase our cost or complexity of doing business, and limit our growth.growth, or impact our results of operations.
Customer misuse of our CPaaS products in violation of the Telephone Consumer Protection Act may cause us to face litigation risk.
The Telephone Consumer Protection Act of 1991 restricts telemarketing and the use of automatic SMS text messages without proper consent. The scope and interpretation of the laws that are or may be applicable to the delivery of text messages are continuously evolving and developing. If we do not comply with these laws or regulations or if we become liable under these laws or regulations due to the failure of our customers to comply with these laws by obtaining proper consent, we could face liability.
Our CPaaS products may be subject to governmental export controls and economic sanctions regulations that could impair our ability to compete in international markets due to licensing requirements and subject us to liability if we are not in compliance with applicable laws.
Our products and services may be subject to export control and economic sanctions regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations and various economic and trade sanctions regulations administered by the U.S. Treasury Department's Office of Foreign Assets Controls. Our products and services must be offered and sold in compliance with these laws and regulations. If we do not comply with these laws or regulations or if we become liable under these laws or regulations due to the failure of our customers to comply with these laws by obtaining proper consent, we could face liability. In addition, changes in our products or services, changes in applicable regulations, or change in the target of such regulations, could also result in decreased use of our products and services, or in our decreased ability to sell our products or provide our services to existing or prospective customers with international operations. Any decreased use of our products and services or limitation on our ability to export our products and provide our services could adversely affect our business, results of operations and financial condition.
If we are unable to establish and expand effective strategic relationships our ability to grow revenues and offer new products under commercially attractive terms may be inhibited, which could adversely affect our business, results of operations, and financial condition.
An element of our strategy is to develop and maintain strategic relationships. We have or are pursuing relationships in the U.S. retail industry as well as with entities in the business markets. The continued development of these relationships may assist us in enhancing our brand, introducing our products and services to larger numbers and types of customers, developing and implementing new products and services, and generating additional revenue. We may not be able to enter into new relationships on economic terms favorable to us. In addition, if we lose any of our important strategic relationships or if strategic relationships fail to benefit us as expected, our ability to grow revenues and offer new products may be inhibited, which could adversely affect our business, results of operations, and financial condition. In addition, inefficiencies or fraud on the part of mass merchant retailers or vendors associated with our assisted selling programs could adversely affect our business, results of operations, and financial condition.
Our business is subject to country-specific governmental regulation and related actions and taxes that may increase our costs or impact our product offerings.
In the United States, Canada, and United Kingdom,many countries, we are not a regulated telecommunications business. Ourbusiness subject primarily to regulations surrounding provision of emergency services are also in use inand payment into universal service type funds. In some countries, outside of the United States, Canada, and the United Kingdom, including countries where providing VoIP services is or may be illegal. We may need to change our service offerings to avoid regulation as a telecommunications business in a jurisdiction, or if we are treated as a fully regulated telecommunications business, we may be required to incur additional expenses. In addition, if governments believe that we are providing unauthorized service in their countries, they may pursue fines, penalties, or other governmental action, including criminal action, that may damage our brand and reputation. If we use a local

15     VONAGE ANNUAL REPORT 2016



partner to provide services in a country and the local partner does not comply with applicable governmental regulations, we may face additional regulation, liabilities, penalties or other governmental action, and our brand and reputation may be harmed.
In addition to the risk of being directly subjected to regulation, decisions by foreign regulators to increase the charge for terminating international calls into their countries may adversely impact our ability to attract and retain international long distance customers in the U.S., U.K., and Canada. For example, our Vonage World offering includes calling to over 60 countries. Regulatory actions in any of these countries, which has occurred in the past, could cause increased costs, impact margin, cause us to remove a country from Vonage World, and impact churn and gross line additions.churn. These regulatory actions may be taken without notice and cause us to react quickly to changing market conditions. These efforts could divert

20     VONAGE ANNUAL REPORT 2018



management’s efforts and attention from ordinary business operations which could materially and adversely affect our results of operations.
As a United States-based company, any foreign subsidiary or joint venture that we use for international operations may be subject to a variety of governmental regulations in the countries where we market our products, including tariffs, taxes and taxes.employment regulations different from those in the U.S. For example, distributions of earnings and other payments, including interest, received from our foreign subsidiaries may be subject to withholding taxes imposed by the jurisdiction in which such entities are formed or operating, which will reduce the amount of after-tax cash we can receive. In general, as a United States corporation, we may claim a foreign tax credit against our federal income tax expense for such foreign withholding taxes and for foreign income taxes paid directly by foreign corporate entities in which we own 10% or more of the voting stock. The ability to claim such foreign tax credits and to utilize net foreign losses is, however, subject to numerous limitations, and we may incur incremental tax costs as a result of these limitations or because we are not currently in a tax-paying position in the United States. We may also be required to include in our income for United States federal income tax purposes our proportionate share of certain earnings of those foreign subsidiaries that are classified as “controlled foreign corporations” without regard to whether distributions have been actually received from such subsidiaries.
Our CPaaS offerings may be subject to liability for historic and future sales, use and similar taxes, that may increase our costs or impact our product offerings.
In some United States tax jurisdictions in which we conduct operations, sales and use and telecommunications taxes could apply to our CPaaS products. Historically, we have not billed or collected these taxes from our CPaaS customers. It is possible that some tax jurisdictions may assert that such taxes are applicable to our CPaaS products, which could result in tax assessments, penalties and interest, and we may be required to collect such taxes on our CPaaS customers in the future. Such tax assessments, penalties and interest or future requirements may adversely affect our business, results of operations and financial condition. To the extent that we decide to collect such taxes from our CPaaS customers in the future, we may have some customers that question the incremental tax charges and some may seek to negotiate lower pricing from us, which could adversely affect our business, results of operations and financial condition.
The global scope of our operations may subject us to potentially adverse tax consequences.
We generally report our taxable income in various jurisdictions worldwide based upon our business operations in those jurisdictions. Intercompany relationships are subject to complex transfer pricing regulations in various jurisdictions. If revenue and taxing authorities disagree with positions we have taken we could be required to pay additional taxes, interest and penalties, which could result in one-time tax charges, higher effective tax rates, reduced cash flows and lower overall profitability of our operations. In addition, changes in tax laws of countries in which we do business could change on a prospective or retroactive basis, and any such changes could increase our liabilities for taxes, interest and penalties, and therefore could harm our business, cash flows, results of operations and financial position.
An unremediated material weakness in our internal control over financial reporting could adversely affect our reputation, business or stock price.
As described under “Item 9A - Controls and Procedures,” we have identified a control deficiency constituting a material weakness in our internal control over financial reporting related to our controls over the preparation of the annual tax provision.  A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis. Although we have developed and are implementing a plan to remediate this material weakness and believe, based on our evaluation to date, that this material weakness will be remediated during 2017, we cannot assure you that this will occur within the contemplated timeframe. Moreover, we cannot assure you that we will not identify additional material weaknesses in our internal control over financial reporting in the future. If we are unable to remediate the material weakness, our ability to record, process and report financial information accurately, and to prepare financial statements within the time periods specified by the rules and forms of the Securities and Exchange Commission, could be adversely affected. The occurrence of or failure to remediate the material weakness may adversely affect our reputation and business and the market price of our common stock and any other securities we may issue.
We are dependent on a small number of individuals, and if we lose key personnel upon whom we are dependent, our business will be adversely affected.
Many of the key responsibilities of our business have been assigned to a relatively small number of individuals. Our future success depends to a considerable degree on the vision, skills, experience, and effort of our senior management. The loss of the services of these officers could have a material adverse effect on our business. In addition, our continued growth depends on our ability to attract and retain experienced key employees.
We are subject to risks that are inherent in operating abroad, including country-specific risks.
Some of our research and development personnel and facilities are located in Israel. Political, economic and military conditions in Israel directly affect our operations. For example, increased violence or armed conflict in the Middle East may disrupt travel and communications in the region, harming our operations there. Furthermore, some of our employees in Israel are obligated to perform up to 36 days of military reserve duty annually and may be called to active duty in a time of crisis. The absence of these employees for significant periods may cause us to operate inefficiently during these periods.
We may be exposed to liabilities under the Foreign Corrupt Practices Act, the UK Bribery Act,anti-corruption, export control and economic sanction regulations, and similar laws and regulations, and any determination that we violated any of these laws or regulations could have a material adverse effect on our business.
We are subject to the Foreign Corrupt Practice Act, ("FCPA"),or FCPA, the UK Bribery Act and other laws that prohibit improper payments or offers of payments to foreign governments and their officials, and political parties, and/or private parties by persons and entities for the purpose of obtaining or retaining business. We have operations, agreements with third parties, and make sales internationally. In addition, we plan to expand our international operations through potential joint ventures with local partners. Our international activities create the risk of unauthorized payments or offers of payments by one of our employees, consultants, partners, sales agents or distributors, even though these parties are not always subject to our control. It is our policy to prohibit these practices by our employees, consultants, partners, sales agents or distributors, however, our existing safeguards and any future improvements may prove to be less than effective, and our employees, consultants, partners, sales agents or distributors may engage in conduct for which we might be held responsible. Violations of the FCPA, the UK Bribery Act or other laws may result in severe criminal or civil sanctions, and we may be subject to other liabilities, which could negatively affect our business, operating results, and financial condition.
Our products and services may be subject to export control and economic sanctions regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations and various economic and trade sanctions regulations administered by the U.S. Treasury Department's Office of Foreign Assets Controls. Our products and services must be offered and sold in compliance with these laws and regulations. If we do not comply with these laws or regulations or if we become liable under these laws or regulations due to the failure of our customers to comply with these laws by obtaining proper consent, we could face liability. In addition, changes in our products or services, changes in applicable regulations, or change in the target of such regulations, could also result in decreased use of our products and services, or in our decreased ability to sell our products or provide our services to existing or prospective customers with international operations. Any decreased use of our products and services or limitation

on our ability to other liabilities, whichexport our products and provide our services could negativelyadversely affect our business, operating results of operations and financial condition.
The success of our business relies on customers’ continued and unimpeded access to broadband service. Providers of broadband services may be able to block our services or charge their customers more for also using our services, which could adversely affect our revenue and growth.
Our customers must have broadband access to the Internet in order to use our service.  Some providers of broadband access, including outside of the United States, may take measures that affect their customers’ ability to use our service, such as degrading the quality of the data packets we transmit over their lines, giving those packets low priority, giving other packets higher priority than ours, blocking our packets entirely or attempting to charge their customers more for also using our services.
In the United States, there continues to be some uncertainty regarding whether suppliers of broadband Internet access have a legal obligation to allow their customers to access and use our service without interference.  On February 26, 2015, the FCC adopted neutrality rules that would protect against interference by suppliers of broadband Internet access. Several parties filed appeals which are pending atOn December 14, 2017, the D.C. Circuit CourtFCC voted to reverse its 2015 neutrality rules. The FCC's recent reversal of Appeals. Oral arguments at the D.C. Circuit Court of Appeals were heldits stance on December 4, 2015. On June 14, 2016, the D.C. Circuit of Appeals denied the appeals. Several parties filednet neutrality may have a petition for rehearing en bancnegative long term impact on July 29, 2016.
If customers do not accept the differences between our service and traditional telephone service, they may choose to remain with their current telephone service provider or may choose to return to service provided by traditional telephone companies.
For certain users, aspects of our service are not the samebusinesses such as traditional telephone service. Our continued growth is dependentours who rely on the adoption of our services by mainstream customers, so these differences are important. For example:

>Both our E-911 and emergency calling services are different, in significant respects, from the 911 service associated with traditional wireline and wireless telephone providers and, in certain cases, with other VoIP providers.
>In the event of a power loss or Internet access interruption experienced by a customer, our service is interrupted. Unlike some of our competitors, we have not installed batteries at customer premises to provide emergency power for our customers’ equipment if they lose power, although we do have backup power systems for our network equipment and service platform.
>Our customers may experience lower call quality than they are used to from traditional wireline telephone companies, including static, echoes, and delays in transmissions.
>Our customers may experience higher dropped-call rates than they are used to from traditional wireline telephone companies.
>Customers who obtain new phone numbers from us do not appear in the phone book and their phone numbers are not available through directory assistance services offered by traditional telephone companies.
>Our customers cannot accept collect calls.
>Our customers cannot call premium-rate telephone numbers such as 1-900 numbers and 976 numbers.
If customers do not accept the differences between our serviceInternet to create and traditional telephone service, they may choose to remain
with their current telephone service provider or may choose to return to service provided by traditional telephone companies.
The debt agreements governing our financing contain restrictions that may limit our flexibility in operating our business or executing on our acquisition strategy.
On June 3, 2016, we entered into Amendment No. 1deliver products and services. Challenges to the AmendedFCC's ruling are underway, with public interest groups, states, local municipalities and Restated Credit Agreement (the “2016 Credit Facility”) consisting of a $125,000 senior secured term loan and a $325,000 revolving credit facility. The 2016 Credit Facility contains customary representations and warranties and affirmative covenants that limit our ability and/or the ability of certain of our subsidiaries to engage in specified types of transactions. These covenants and other restrictions may under certain circumstances limit, but not necessarily preclude, our and certain of our subsidiaries’ ability to, among other things:

>consolidate or merge;
>create liens;
>incur additional indebtedness;
>dispose of assets;
>consummate acquisitions;
>make investments; or
>pay dividends and other distributions.
Under the 2016 Credit Facility, we are required to comply with the following financial covenants: specified maximum consolidated leverage ratio, specified minimum consolidated fixed coverage charge ratio, minimum cash position and maximum capital expenditures. Our ability to comply with such financial and other covenants may be affected by events beyond our control, so we may not be able to comply with these covenants. A breach of any such covenant could result in a default under the 2016 Credit Facility. In that case, the lenders could elect to declare due and payable immediately all amounts due under the 2016 Credit Facility, including principal and accrued interest.
Significant foreign currency exchange rate fluctuations could adversely affect our financial results.
Because our consolidated financial statements are presented in U.S. dollars, increases or decreasescompanies seeking redress in the value of the U.S. dollar relative to other currencies in which we transact business could materially adversely affect our financial results. For example, Nexmo collects revenues in Euros, and accordingly the strengthening of the U.S. dollar relative to the Euro adversely affects our revenue and operating results presented in U.S. dollars. In addition, on June 23, 2016, the United Kingdom (U.K.) held a referendum in which a majority of voters approved an exit from the European Union (E.U.), commonly referred to as "Brexit." As a result of the referendum, it is expected that the British government will begin negotiating the terms of the U.K.'s withdrawal from the E.U. Brexit caused significant volatility in global stock markets and currency exchange rate fluctuations that resulted in the strengthening of the U.S. dollar against foreign currencies in which we conduct business, such as the British Pound, Euro and other currencies. Such strengthening of the U.S. dollar relative to other currencies may adversely affect our revenue and operating results. In addition, changes to U.K. border and immigration policy could likewise occur as a result of Brexit, affecting our U.K. operation's ability to recruit and retain employees from outside the U.K.
The market price of our common stock has been and may continue to be volatile, and purchasers of our common stock could incur substantial losses.
Securities markets experience significant price and volume fluctuations. This market volatility, as well as general economic conditions, could cause the market price of our common stock to fluctuate substantially. The trading price of our common stock has been, and is likely to continue to be, volatile. Many factors that are beyond our control may significantly affect the market price of our shares. These factors include:

17     VONAGE ANNUAL REPORT 2016




>changes in our earnings or variations in operating results;
>any shortfall in revenue or increase in losses from levels expected by securities analysts;
>judgments in litigation;
>operating performance of companies comparable to us;
>general economic trends and other external factors; and
>market conditions and competitive pressures that prevent us from executing on our future growth initiatives.
If any of these factors causes the price of our common stock to fall, investors may not be able to sell their common stock at courts and/or above their respective purchase prices.
If we require additional capital, we may not be able to obtain additional financing on favorable terms or at all.
We may need to pursue additional financing to respond to new competitive pressures, pay extraordinary expenses such as litigation settlements or judgments or fund growth, including through acquisitions. Because of our past significant losses and our limited tangible assets, we do not fit traditional credit lending criteria, which, in particular, could make it difficult for us to obtain loans or to access the capital markets. In addition, the credit documentation for our recent financing contains affirmative and negative covenants that affect, and in many respects may significantly limit or prohibit, among other things, our and certain of our subsidiaries’ ability to incur, refinance or modify indebtedness and create liens.
Our credit card processors have the ability to impose significant holdbacks in certain circumstances. The reinstatement of such holdbacks likely would have a material adverse effect on our liquidity.
Under our credit card processing agreements with our Visa, MasterCard, American Express, and Discover credit card processors, the credit card processor has the right, in certain circumstances, including adverse events affecting our business, to impose a holdback of our advanced payments purchased using a Visa, MasterCard, American Express, or Discover credit card, as applicable, or demand additional reserves or other security. If circumstances were to occur that would allow any of these processors to reinstate a holdback, the negative impact on our liquidity likely would be significant. In addition, our Visa and MasterCard credit card processing agreement may be terminated by the credit card processor at its discretion if we are deemed to be financially insecure. As a significant portion of payments to us are made through Visa and MasterCard credit cards, if the credit card processor does not assist in transitioning our business to another credit card processor, the negative impact on our liquidity likely would be significant. There were no cash reserves and cash-collateralized letters of credit with any credit card processors as of December 31, 2016.legislation.
We have incurred cumulative losses since our inception and may not achieve consistent profitability in the future.
While we achievedWe incurred a net income attributable to Vonage of $17,907$35,728 for the year ended December 31, 2016,2018 and our accumulated deficit is $637,113$611,985 from our inception through December 31, 2016.2018. Although we have achieved profitability in prior years and believe we will achieve consistent profitability in the future, we ultimately may not be successful.  We believe that our ability to achieve consistent profitability will depend, among other factors, on our ability to continue to achieve and maintain substantive operational improvements and structural cost reductions while maintaining and growing our net revenues.  In addition, certain of the costs of our business are not within our control and may increase.  For example, we and other telecommunications providers are subject to regulatory termination charges imposed by regulatory authorities in countries to which customers make calls, such as India where regulatory authorities
have been petitioned by local providers to consider termination rate increases. As we attract additional international long distance callers, we will be more affected by these increases to the extent that we are unable to offset such costs by passing through price increases to customers.calls.
We may be unable to fully realize the benefits of our net operating loss, (“NOL”)or NOL, carry forwards if an ownership change occurs.
If we were to experience a “change in ownership” under Section 382 of the Internal Revenue Code, (“or Section 382”),382, the NOL carry forwardcarryforward limitations under Section 382 would impose an annual limit on the amount of the future taxable income that may be offset by our NOL generated prior to the change in ownership. If a change in ownership were to occur, we may be unable to use a significant portion of our NOL to offset future taxable income. In general, a change in ownership occurs when, as of any testing date, there has been a cumulative change in the stock ownership of the corporation held by 5% stockholders of more than 50 percentage points over an applicable three-year period. For these purposes, a 5% stockholder is generally any person or group of persons that at any time during an applicable three-year period has owned 5% or more of our outstanding common stock. In addition, persons who own less than 5% of the outstanding common stock are grouped together as one or more “public group” 5% stockholders. Under Section 382, stock ownership would be determined under complex attribution rules and generally includes shares held directly, indirectly (thoughthrough intervening entities),entities, and constructively (byby certain related parties and certain unrelated parties acting as a group).group. We have implemented a Tax Benefits Preservation Plan intended to provide a meaningful deterrent effect against acquisitions that could cause a change in ownership, however this is not a guarantee against such a change in ownership.
Our certificate of incorporation and bylaws and the agreements governing our indebtedness contain provisions that could delay or discourage a takeover attempt, which could prevent the completion of a transaction in which our stockholders could receive a substantial premium over the then-current market price for their shares.
Certain provisions of our restated certificateRestated Certificate of incorporationIncorporation and our second amendedAmended and restated bylawsRestated By-laws may make it more difficult for, or have the effect of discouraging, a third party from acquiring control of us or changing our board of directors and management. These provisions:

A classified structure will therefore remain in place during the phase-in period.
Such provisions could have the effect of depriving stockholders of an opportunity to sell their shares at a premium over prevailing market prices. Any delay or prevention of, or significant payments required to be made upon, a change of control transaction or changes in our board of directors or management could deter potential acquirors or prevent the completion of a transaction in which our stockholders could receive a substantial premium over the then-current market price for their shares.

IP Matters
Bear Creek Technologies, Inc. On February 22, 2011, Bear Creek Technologies, Inc. (“Bear Creek”) filed a lawsuit against Vonage Holdings Corp., Vonage America Inc., Vonage Marketing LLC, and Aptela Inc. (the latter two entities being former subsidiaries of Vonage Holdings Corp. now merged into Vonage America Inc. and Vonage Business Inc., respectively) in the United States District Court for the Eastern District of Virginia alleging that Vonage’s and Aptela’s products and services are covered by United States Patent No. 7,889,722, entitled “System for Interconnecting Standard Telephony Communications Equipment to Internet Protocol Networks” (the “'722 Patent”). The suit also named numerous other defendants. On August 17, 2011, the Court dismissed Bear Creek’s case against the Vonage entities and Aptela, and all but one of the other defendants. Later, on August 17, 2011, Bear Creek re-filed its complaint in the United States District Court for the District of Delaware against the same Vonage entities; and re-filed its complaint in the United States District Court for the Eastern District of Virginia against Aptela. On May 2, 2012, the litigations against Vonage and Aptela were consolidated for pretrial proceedings with twelve other actions in the District of Delaware. Vonage filed an answer to Bear Creek’s complaint, including counterclaims of non-infringement and invalidity of the ‘722 patent. Aptela, which filed a motion to dismiss Bear Creek’s complaint on September 27, 2011, has not yet answered, as its motion remains pending. On November 5, 2012, Bear Creek filed an answer to Vonage’s counterclaims. On July 17, 2013, the Court stayed the case pending resolution of the reexamination of the ‘722 patent requested by Cisco Systems, Inc. (“Cisco”), described below. On May 5, 2015, the Court closed the case, with leave to reopen if further attention by the Court is required.
A request for reexamination of the validity of the ‘722 Patent was filed on September 12, 2012 by Cisco. Cisco’s request was granted on November 28, 2012. On March 24, 2014, the United States Patent and Trademark Office issued an Action Closing Prosecution, confirming its rejection of all claims of the ‘722 patent. Bear Creek’s November 14, 2014 appeal of that decision to the Patent Trial and Appeal Board was denied on December 29, 2015. Bear Creek appealed the Board’s decision to the United States Court of Appeals for the Federal Circuit. Briefing on the appeal is complete and pending oral argument before the Court on March 13, 2017.
RPost Holdings, Inc. On August 24, 2012, RPost Holdings, Inc., RPost Communications Limited, and RMail Limited (collectively,
“RPost”) filed a lawsuit against StrongMail Systems, Inc. (“StrongMail”) in the United States District Court for the Eastern District of Texas alleging that StrongMail’s products and services, including its electronic mail marketing services, are covered by United States Patent Nos. 8,224,913, 8,209,389, 8,161,104, 7,966,372, and 6,182,219. On February 11, 2013, RPost filed an amended complaint, adding 27 new defendants, including Vonage America Inc. RPost’s amended complaint alleges willful infringement of the RPost patents by Vonage and each of the other new defendants because they are customers of StrongMail. StrongMail has agreed to fully defend and indemnify Vonage in this lawsuit. Vonage answered the complaint on May 7, 2013. On September 17, 2015, the Court ordered the consolidation for pre-trial purposes of this case with other cases by RPost. The lead case has been administratively closed and stayed since January 30, 2014 due to multiple pending actions by third parties regarding ownership of the patents at issue. On December 1, 2016, the parties in the consolidated actions filed a joint notice regarding status of the co-pending actions. Plaintiffs requested that the stay be lifted, while defendants maintain that the stay should remain in place. 
AIP Acquisition LLC. On January 3, 2014, AIP Acquisition LLC (“AIP”), filed a lawsuit against Vonage Holdings Corp., Vonage America, Inc., and Vonage Marketing LLC in the U.S. District Court for the District of Delaware alleging that Vonage’s products and services are covered by United States Patent No. 7,269,247. Vonage filed an answer and counterclaims on February 25, 2014. AIP filed an amended complaint on March 18, 2014, which Vonage answered on April 4, 2014. On April 8, 2014, the Court stayed the case pending final resolution of non-party Level 3’s inter partes review request of United States Patent No. 7,724,879, which is a continuation of the ‘247 patent. On October 8, 2014, the Patent Office issued a Final Written Decision, finding all challenged claims of the ‘879 patent to be invalid. On November 10, 2015, the Federal Circuit rejected AIP’s appeal and affirmed the Patent Office’s rejection of the ‘879 patent.
Cisco petitioned for inter partes review of the ‘247 patent on November 25, 2014, which was granted on May 20, 2015. On May 18, 2016, the Patent Office issued a Final Written Decision, finding all challenged claims of the ‘247 patent to be invalid. AIP appealed to the Federal Circuit, filing its opening brief on December 15, 2016. On December 20, 2016, the Patent Office filed a notice of intervention in the appellate proceedings. Both the Patent Office’s and Cisco’s responsive briefs are due on March 13, 2017.
Commercial Litigation
Merkin & Smith, et als. On September 27, 2013, Arthur Merkin and James Smith filed a putative class action lawsuit against Vonage America, Inc. in the Superior Court of the State of California, County of Los Angeles, alleging that Vonage violated California’s Unfair Competition Law by charging its customers fictitious 911 taxes and fees. On October 30, 2013, Vonage filed a notice removing the case to the United States District Court for the Central District of California. On November 26, 2013, Vonage filed its Answer to the Complaint. On December 4, 2013, Vonage filed a Motion to Compel Arbitration, which the Court denied on February 4, 2014. On March 5, 2014, Vonage appealed that decision to the United States Court of Appeals for the Ninth Circuit. On March 26, 2014, the district court proceedings were stayed pending the appeal. On February 29, 2016, the Ninth Circuit reversed the district court’s ruling and remanded with instructions to grant the motion to compel arbitration. On March 22, 2016, Merkin and Smith filed a petition for rehearing. On May 4, 2016, the Ninth Circuit withdrew its February 29, 2016 decision and issued a new order reversing the district court’s order and remanded with instructions to compel arbitration. The Ninth Circuit also declared as moot the petition for rehearing. On June 27, 2016, the lower court stayed the case pending arbitration. A joint status report was filed with the District Court on December 23, 2016.
Regulation
Telephony services are subject to a broad spectrum of state and federal regulations. Because of the uncertainty over whether Voice

20     VONAGE ANNUAL REPORT 2016



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.
Federal - Net Neutrality
Clear and enforceable net neutrality rules make it more difficult for broadband Internet service providers to block or discriminate against Vonage service. In addition, explicitly applying net neutrality rules to wireless broadband Internet service providers could create greater opportunities for VoIP applications that run on wireless broadband Internet service. In December 2010, the FCC adopted net neutrality rules that applied strong net neutrality rules to wired broadband Internet service providers and limited rules to wireless broadband Internet service providers. On January 14, 2014, the D.C. Circuit Court of Appeals vacated a significant portion of the 2010 rules. On May 15, 2014, the FCC issued a Notice of Proposed Rulemaking (NPRM) proposing new net neutrality rules. After public response to the NPRM, the FCC adopted new neutrality rules on February 26, 2015. These rules prohibit broadband Internet service providers from: (1) blocking or throttling lawful content applications, or services; (2) imposing paid prioritization arrangements; and (3) unreasonably interfering or unreasonably disadvantaging consumers or edge providers. In addition, broadband Internet service providers are required to make certain disclosures regarding their network management practices, network performance, and commercial terms. These net neutrality rules apply the same requirements to wired and wireless broadband Internet service providers. Several parties have filed appeals which are pending at the D.C. Circuit Court of Appeals. Oral arguments at the D.C. Circuit Court of Appeals were held on December 4, 2015. On June 14, 2016, the D.C. Circuit of Appeals denied the appeals. Several parties filed a petition for rehearing en banc on July 29, 2016. The petition is pending.
Federal - Lifeline Reform
On March 31, 2016, the FCC adopted an order modernizing the Lifeline program. The Lifeline program previously subsidized voice service for low-income customers and is one component of the federal universal service fund. The order refocuses the program to subsidize broadband. Increased adoption of broadband services expands the market for Vonage services. The order will also likely increase the overall size of the federal universal fund and lead to increased USF contribution levels for Vonage services subject to assessment for federal USF.
Federal - Rural Call Completion Issues
On February 7, 2013, the FCC released a Notice of Proposed Rulemaking (NPRM) on rural call completion issues. The NPRM proposed new detailed reporting requirements to gauge rural call completion performance. Rural carriers have argued that VoIP provider call completion performance to rural areas is generally poor. On October 28, 2013, the FCC adopted an order on rural call completion imposing new reporting obligations and restricting certain call signaling practices. The call signaling rules went into effect on January 31, 2014. We filed for extensions of the rules, which the FCC granted, and as of April 17, 2014, we were compliant with the FCC call signaling rules. The effective date for the reporting requirements was April 1, 2015. We could be subject to an FCC enforcement action in the future in the event the FCC took the position that our rural call completion performance is inadequate or we were not compliant with the FCC’s order.
Federal - Numbering Rights
On April 18, 2013, the FCC issued a Notice of Proposed Rulemaking (NPRM) that proposed to modify FCC rules to allow VoIP providers to directly access telephone numbers. In addition, the FCC granted a waiver from its existing rules to allow Vonage to conduct a trial of direct access to telephone numbers. The trial would allow the FCC to obtain real-world data on direct access to telephone numbers
by VoIP providers to inform consideration of the NPRM. Direct access to telephone numbers would facilitate IP to IP interconnection, which may allow VoIP providers to provide higher quality, lower cost services, promote the deployment of innovative new voice services, and experience reductions in the cost of telephony services. Vonage successfully completed the trial in certain markets and filed the required reports on the trial with the FCC. On January 31, 2014, the FCC Wireline Competition Bureau issued a positive report on the trial, concluding that Vonage's successful trial confirmed the technical feasibility of interconnected VoIP providers obtaining telephone numbers directly from the numbering administrators. On June 18, 2015, the FCC adopted an order that modifies its rules to allow interconnected VoIP providers to directly access telephone numbers. Part of the order required approval from the Office of Management and Budget ("OMB") prior to the rule change becoming effective. On February 4, 2016, the FCC announced that OMB had approved the order and would begin accepting applications for authorization beginning on February 18, 2016. Vonage applied for authorization, and on March 31, 2016 received authorization. On December 23, 2015, the National Association of Regulatory Utility Commissioners filed an appeal of the June 18, 2015 FCC order at the D.C. Circuit Court of Appeals. The D.C. Circuit held oral argument on this appeal on February 8, 2017.
Federal - Privacy Rules
On April 1, 2016, the FCC issued a Notice of Proposed Rulemaking (NPRM) that proposed the adoption of privacy rules for providers of broadband Internet access service and updating its rules for voice services to make them consistent with the proposed privacy rules for broadband Internet access services. In addition to regulating customer proprietary network information (CPNI), a category of information that the FCC has traditionally regulated for voice services, the FCC proposed to regulate use of customer personal information (PI), a broader set of information than CPNI, by broadband and voice service providers. Further, the NPRM would regulate voice and broadband provider privacy policies and data security practices, including imposing vicarious liability for vendors who handle PI and CPNI on behalf of a broadband or voice provider. Finally, the NPRM would impose another data breach reporting notification obligation on voice and broadband providers on top of existing state data breach notification requirements. The FCC adopted its new privacy rules at its October 27, 2016 open meeting. The rules do not provide for vicarious liability for vendors and provide an exemption from the rules in certain instances for business voice customers. Numerous parties have filed petitions for reconsideration.
State Telecommunications Regulation
In general, the focus of interconnected VoIP telecommunications regulation is at the federal level. On November 12, 2004, the FCC issued a declaratory ruling providing that our service is subject to federal regulation and preempted the Minnesota Public Utilities Commission (“MPUC”) from imposing certain of its regulations on us. The FCC's decision was based on its conclusion that our service is interstate in nature and cannot be separated into interstate and intrastate components. On March 21, 2007, the United States Court of Appeals for the 8th Circuit affirmed the FCC's declaratory ruling preempting state regulation of our service.
While this ruling does not exempt us from all state oversight of our service, it effectively prevents state telecommunications regulators from imposing certain burdensome and inconsistent market entry requirements and certain other state utility rules and regulations on our service. State regulators continue to probe the limits of federal preemption in their attempts to apply state telecommunications regulation to interconnected VoIP service. On July 16, 2009, the Nebraska Public Service Commission and the Kansas Corporation Commission filed a petition with the FCC seeking a declaratory ruling or, alternatively, adoption of a rule declaring that state authorities may apply universal service funding requirements to nomadic VoIP providers. We participated in the FCC proceedings on the petition. On November 5, 2010, the FCC issued a declaratory ruling that allowed states to assess state USF on nomadic VoIP providers on a going forward basis provided that the states comply with certain conditions to ensure that imposing state USF does not conflict with federal law or policy. More recently on July 28, 2015, the MPUC found that it has

21     VONAGE ANNUAL REPORT 2016



authority to regulate Charter’s fixed, interconnected VoIP service. Charter challenged the MPUC’s order at the U.S. District Court for Minnesota. This challenge is currently pending. We expect that state public utility commissions and state legislators will continue their attempts to apply state telecommunications regulations to VoIP service.
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 a reserve of $1,763 as of December 31, 2016 as our best estimate of the potential tax exposure for any retroactive assessment. We believe the maximum estimated exposure for retroactive assessments is approximately $2,600 as of December 31, 2016.

Through our acquisition of Nexmo in 2016, weWe 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. 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 small and medium business, or 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.
Our Business strategy isWith our ability to supportintegrate these cloud-based, workplace tools, Vonage integrates the full range ofentire business communications value chain - from employee communications that maximize productivity to the direct engagement with customers using two product families: Vonage Essentials, based onthat CPaaS provides. When combined with our proprietary call processing platform that is purpose-built for SMB and mid-market customers; and Vonage Premier, based on Broadsoft’s call processing platform in combination with other Vonage cloud based solutions, which serves larger customers, from mid-market businesses through large enterprises. We also organized our salesforce to address the full business market. We believe operating two platforms at scale enables us to deliver the right products and solutions to address the needs of diverse customers while maximizing our subscriber economics, regardless of segment served. Revenues are generated primarily through the sale of subscriptions for our UCaaS services. Our revenue generation efforts are focused on customer acquisition and retentionMPLS network, as well as providing additionalvoice 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 customers as they grow and scale.
Our diverse customer base spans a wide varietysuite of industries, including manufacturing, automotive, legal, information technology, financial services, construction, real estate, engineering, healthcare, and non-profit.
Vonage Essentials. Vonage Essentials customers subscribe to our cloud-based communication services, delivered through our proprietary platform that is purpose-built for SMB and mid-market customers. Essentials provides a cost-effective, scalable, feature-rich solution, delivered over-the-top of a customer’s broadband, typically month-to-month without a commitment. Vonage Essentials is sold primarily through our direct telesales and online channels, and is increasingly sold through our channel partners and field sales teams. We believe the strength of the Vonage brand directly contributes to a lower-cost customer acquisition model and provides attractive subscriber economics.
Vonage Premier. Our Vonage Premier offerings are tailor-made for the large mid-market and enterprise segments. Vonage Premier is a feature-rich/fully managed solution that utilizes Broadsoft Inc.’s ("Broadsoft") enterprise-grade call processing platform, in combination with other cloud services like advanced contact center, video conferencing and speak2dial, and can be provided with high-level quality of service ("QoS"), which is generally delivered over our national MPLS network, with 21 network Points of Presence (POPs) across the country. Vonage can also provide QoS-level quality over-the-top of the customer’s broadband through our Smart-WAN router solution. Customers value our proprietary provisioning and feature-management tool, named Zeus, which enables the rapid deployment of solutions directly by Vonage while giving full visibility to our channel partners and our customers. Further differentiating Vonage is our robust service delivery team comprised of team members specializing in project management, voice and data provisioning, and line number porting. This team is intensely focused on providing an outstanding customer experience, and is rapidly becoming a competitive differentiator.
Our Vonage Premier offering is sold primarily through our channel partners, and our field and enterprise sales teams, and generally requires a three-year contract. We are a preferred provider for many of the largest master agents in the country, harnessing a network of over 20,000 sub agents selling both Vonage Premier and Vonage Essentials. We believe we have one of the largest multi-channel distribution sales platforms in our industry to serve the full range of business customers. We plan to capitalize on the growing adoption of cloud-based communications and collaboration solutions by continuing to expand our salesforce, expand into new markets, and enhance our relationships with existing customers to provide additional functionality and overall business value that can be achieved with our UCaaS platform.
Nexmo, the Vonage API Platform. We are a global leader in the CPaaS segment of the cloud communications market, providing innovative communication APIs for text messaging and voice communications, allowing developers and enterprisesservices available to embed contextual communications into mobile apps, websites and business workflows via text, social media, chat apps and voice. With just few lines of code, developers can send and receive text messages and build programmable voice applications. Nexmo, the Vonage API Platform can scale from one API call to billions. The platform makes it easy for any of our over 200,000 developers to access communication services via software and APIs. Through Nexmo we have a global network of interconnected carriers delivering our API-based communications platform, enabling businesses to communicate with their customers reliably and with ease, no matter where in the world they are located. The addition of our Nexmo products to our Business offering allows our customers to address their full communications needs, from employee

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,their existing internet connections, including over 3G,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 ethnic segments. The markets for international long distance allow us to leverage our VoIP network by providing customers a low-cost and feature-rich alternative to services offered by telecom, cable, and international calling card providers.
We generate revenue through the acquisition and retention of Consumer customers. We are focused on optimizing the Consumer business for profitability to improve the strong cash flows of the business. During 2016, we continued our disciplined focus on marketing efficiency by shifting customer acquisition spend to our higher performing channels, improving the quality of customers we acquire and driving lower churn, all of which drive higher customer life-time value. This focus has led to a reallocation of marketing spend to our Business segment.
The result of these initiatives has been to create a strong cash flow business which provides financial stability, as well as cost synergies and structural advantages to our Business segment.
Services outside of the United States.
We currently have UCaaS and consumer operations in the United States, United Kingdom, and Canada and believe that our low-cost Internet based communications platform enables us to cost effectively deliver voice and messaging services to other locations throughout the world. Through Nexmo, we have operations in the United States, United Kingdom, Hong Kong, and Singapore, and provide CPaaS solutions to our customers located in many countries around 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.

28     VONAGE ANNUAL REPORT 2018



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. In addition, such competitors may in the future require new customers or existing customers making changes to their service to purchase voice services when purchasing
high speed Internet access. Further, as wireless providers offer more minutes at lower prices, better coverage, and companion landline alternative services, their services have become more attractive to households as a replacement for wireline service. We also compete against alternative communication providers, such as magicJack, Skype, and Google Voice.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. In addition, our competitors have partnered and may in the future partner with other competitors to offer products and services, leveraging their collective competitive positions. 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.
Regulation.  Our business has developed in a relatively lightly regulated environment. The United States and other countries, however, are examining how VoIP services should be regulated. In particular, state telecommunications regulators continueFor further discussion regarding regulatory issues which impacts the Company, refer to try to regulate VoIP service despite the FCC’s 2004 Vonage Preemption Order that preempted state regulation. For example, on July 28, 2015, the Minnesota Public Utility Commission found that it has authority to regulate Charter’s ‘fixed' interconnected VoIP service. In addition to regulatory matters that directly address VoIP, a number of other regulatory initiatives could impact our business. One such regulatory initiative is net neutrality. On February 26, 2015, the FCC adopted strong net neutrality rules. On June 14, 2016, the D.C. Circuit of Appeals denied the upheld these rules.  Several parties requested rehearing en banc.  These petitions are currently pending.  See also the discussion under "Regulation" in Note 1011, Commitments and Contingencies to our financial statements for a discussion of regulatory issues that impact us.statements.
Key Operating Data
Through our acquisitions of Vocalocity, Telesphere, Simple Signal, iCore, and Nexmo, our business has substantially evolved in recent quarters, with business customers now accounting for a substantial and growing portion of overall revenues. To reflect this evolution, we have made certain changes to our key operating data and income statement presentation to provide greater visibility into the operating metrics of the business. The key changes to the income statement include the combination of sales and marketing expenses into a new sales and marketing caption, separated from selling, general, and administrative expenses. A new line item entitled engineering and development has also been created, reflecting the cost of developing new products and technologies and supporting our service platforms. The remaining selling, general and administrative expenses after the above reclassifications have been renamed general and administrative expenses. The reclassifications have been reflected in all periods presented and had no impact on net earnings previously reported.

Service revenues per seatcustomer increased from $42.79$327 for 20152017 to $44.94$358 for 2016 due2018 primarily driven by the Company's successful efforts to attract larger business customers and to expand services provided to our successful acquisitions and subsequent organic growth in the mid-market and enterprise space.existing business customers.
Seats. Seats include, as of a particular date, all paid seats from which a customer can make an outbound telephone call on that date and virtual seats. Seats exclude electronic fax lines and toll free numbers, which do not allow outbound telephone calls by customers. Seats increased from 541,884 as of December 31, 2015 to 638,096 as of December 31, 2016. This increase is due to continued growth in our business customers as we have increased marketing investment to attract these more profitable customers. It also includes 48,920 seats existing at Telesphere at the time of acquisition, 35,256 seats existing at Simple Signal at the time of acquisition, and 86,309 seats existing at iCore at the time of acquisition.
RevenueBusiness revenue churn. RevenueBusiness revenue churn is calculated by dividing the monthly recurring revenue from customers or customer locations that have terminatedbeen confirmed to be foregone during
a period by the simple average of the total monthly recurring 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 given period.customer’s contracted service plan, regulatory fees charged to customers, and credits. The simple average of total monthly recurring revenue from all customers during the period is the total monthly recurring revenue as defined herein on the first day of the period, plus the total monthly recurring 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. RevenueBusiness revenue churn increaseddecreased slightly from 1.2% for the year ended 2015in 2017 to 1.4% for the year ended 2016. Revenue churn was flat at 1.4% for the three months ended December 31, 2016 and for the three months ended September 30, 2016, and increased from 1.1% for the three months ended December 31, 2015.in 2018.  Our revenue churn will 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.

Revenues. Consumer revenues represents revenue from our consumer customers including revenues from our legacy business customers using Vonage VoIP products.


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 decreasedincreased from $27.58$26.19 for 20152017 to $26.43$26.42 for 20162018 due primarily to new, lower, pricing structures implemented in 2015 and lower ILD pay-per-use revenue.the Company's ability to retain its more tenured customers.
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 1,940,8251,492,067 as of December 31, 20152017 to 1,711,3661,287,649 as of December 31, 2016,2018, 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. In addition, beginning October 1, 2014, the Company no longer
charges for second line mobile Extensions provided to customers, which resulted in a decrease in subscriber lines of 78,949. Future period subscriber line metrics will continue to reflect the reduction in paid subscriber lines resulting from this benefit to customers.
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 decreased to 2.2%1.8% for 20162018 from 2.3%2.0% for 2015.The decrease2017. The decreased was due primarily to our decision to maximize customer value by focusing marketing spend on higher return channels and away from assisted selling channels which had higher early life churn. Customer churn was flat at 2.2% for the three months ended December 31, 2016, for the three months ended September 30, 2016, and for the three months ended December 31, 2015. 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

30     VONAGE ANNUAL REPORT 2016



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. Customer churn differs from our previously reported average monthly customer churn in that our business customers are no longer included in this metric. See the discussion below for detail regarding churn impacting our business customers.
REVENUES
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. The “Vonage World” plan, available in the United States and Canada, offers unlimited calling across the United States and Puerto Rico, unlimited international calling to over 60 countries including India, Mexico, and China, subject to certain restrictions, and free voicemail to text messages with Vonage Visual Voicemail. Each of our unlimited plans other than Vonage World offers unlimited domestic calling as well as unlimited calling to Puerto Rico, Canada, and selected European countries, subject to certain restrictions. Each of our basic plans offers a limited number of domestic calling minutes per month. We offer similar plans in Canada. Under our basic plans, we charge on a per minute basis when the number of domestic calling minutes included in the plan is exceeded for a particular month. International calls (except for calls to Puerto Rico, Canada and certain European countries under our unlimited plans and a variety of countries under international calling plans and Vonage World) are charged on a per minute basis. These per minute fees are not included in our monthly subscription fees. Through our acquisitions of Vocalocity, Telesphere, Simple Signal, and iCore, 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. The service plans include an array of basic and enhanced features applicable to the needs of SMB and SOHO customers. 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, through our acquisition of Nexmo 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.
We derive most Services revenue is offset by the cost of our services revenue from monthly subscription fees thatcertain customer acquisition activities, such as rebates and promotions. In addition, in certain instances, we charge our customers under our service plans. We also offer consumer fax service, virtual phone numbers, toll free numbers and other services, and charge an additional monthly fee for each service. We automatically charge thesedisconnect fees to our customers’ credit cards, debit cards, or electronic check payments (“ECP”), monthly in advance. We also automatically charge the per minute fees not included in our monthly subscription fees to our customers’ credit cards, debit cards or ECP monthly in arrears unless they exceed a certain dollar threshold, in which case they are charged immediately.
By collecting monthly subscription fees in advance and certain other charges immediately after they are incurred, we are able to reduce the amount of accounts receivable that we have outstanding, thus allowing us to have lower working capital requirements. Collecting in this manner also helps us mitigate bad debt losses, which are recordedrecognized as a reduction to revenue. If a customer’s credit card, debit card or ECP is declined, we generally suspend international calling capabilities as well asrevenue at the customer’s ability to incur domestic usage charges in excess of their plan minutes. Historically, in most cases, wetime the disconnect fees are able to correct the problem with the customer within the current monthly billing cycle. If the customer’s credit card, debit card or ECP could not be successfully processed during three billing cycles (i.e., the current and two subsequent monthly billing cycles), we terminate the account.
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, (“USF”)or USF, and related fees. All other taxes are recorded on a net basis.
In addition, in certain instances, we charge disconnect fees whichRevenues are recognized as revenue at the time the disconnect fees are collected from our customer.

For the year ended December 31, 2018 compared to the year ended December 31, 2017
Total revenues increased 5% for the year ended December 31, 2018 as compared to the prior year period. The increase is primarily due to business customer growth driving an increase in revenues of $109,222, offset by declining consumer revenues of $62,726 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 5% for the year ended December 31, 2018 as compared to the prior year period driven by increased costs incurred in servicing our business customers of $59,758 due to communicate with theiran increase in customers year over year. This was partially offset by a decrease in costs in Consumer of $37,717 as subscriber lines continues to decline resulting in lower international and employees through any cloud-connected device, in any place, at any time without the often costly investment required with on-site equipment.

The Company continues to ourallocate resources toward the growth of its Business communication services and expects this trend of Business revenue growth partially offset by the declining Consumer business.

For the three years ended December 31, 2016, 2015,2018, 2017, and 20142016 we generated incomecash from operations. 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.

Operating Activities
Cash provided by operating activities decreased to $123,205 for the year ended December 31, 2018 compared to $128,058 for the year ended December 31, 2017, primarily due to a decrease of $73,071 in non-cash items offset by an increase in net income. Also attributing to the decrease in operating activities was an increase in cash used for working capital requirements of $1,443 during the year ended December 31, 2018 as compared to the year ended December 31, 2017 primarily due payment of acquisition related expenses made during the current year.
Cash provided by operating activities increased to $128,058 for the year ended December 31, 2017 as compared to $93,456 for the year ended December 31, 2016 primarily due to an increase in operating income adjusted for non-cash items of $27,817 driven by a decrease in operating expenses as compared to the year ended December 31, 2016 primarily attributable to decreased sales and marketing costs. Also attributing to the increase in operating activities was a decrease in cash used for working capital requirements of $6,785 during the year ended December 31, 2017 as compared to the year ended December 31, 2016 primarily due to a decrease in timing of prepayments made during the current year.
Investing Activities
Cash used in investing activities for the year ended December 31, 2018 of $407,230, which was an increase from cash used in investing activities of $30,737 during the year ended December 31, 2017, was primarily attributable to the acquisitions of NewVoiceMedia and TokBox of $380,484, net of cash acquired, slightly offset by a decrease in costs associated with capital expenditures and acquisition and development of software.
Cash used in investing activities for the year ended December 31, 2017 of $30,737, which was a decrease from cash used in investing activities of $191,449 during the year ended December 31, 2016 was primarily attributable to payments of $163,042 made during the prior year to acquire Nexmo slightly offset by a decrease in cash provided from the maturity and sale of marketable securities of $14,389.
Financing Activities
Cash provided by financing activities was $258,212 for the year ended December 31, 2018 as compared to cash used in financing activities of $96,242 during the year ended December 31, 2017. The increase in cash provided by financing activities was primarily attributable to proceeds received from the credit facilities, net of principal payments of $373,562, slightly offset by an increase in shares withheld for payment of employee taxes and a decrease in share repurchased.
Cash used by financing activities was $96,242 for the year ended December 31, 2017 as compared to cash provided by financing activities of $68,054 during the year ended December 31, 2016. The decrease in cash provided by financing activities was primarily attributable increased payments for financing arrangements net of new borrowings of $195,188 slightly offset by fewer repurchases of common stock of $23,360 during the current year.

the closing date of $241, resulting in a total acquisition cost of $114,330. We financed the transaction through $24,603 of cash (of which $3,610 was paid in January 2015) and $67,000 from our 2014 revolving credit facility.
2016 Financing
On June 3, 2016, we entered into Amendment No. 1 to the Amended and Restated Credit Agreement (the “2016 Credit Facility”) consisting of a $125,000 term note and a $325,000 revolving credit facility. The co-borrowers under the 2016 Credit Facility are the Company and Vonage America Inc., the Company’s wholly owned subsidiary. Obligations under the 2016 Credit Facility are guaranteed, fully and unconditionally, by the Company’s other United States material subsidiaries and are secured by substantially all of the assets of each borrower and each guarantor. The lenders under the 2016 Credit Facility are JPMorgan Chase Bank, N.A., Citizens Bank, N.A., Fifth Third Bank, MUFG Union Bank, N.A., Silicon Valley Bank, SunTrust Bank, Keybank National Association, Santander Bank, N.A., Capital One National Association, and First Niagara Bank, N.A.

Morgan Securities LLC, Citizens Bank, N.A., Fifth Third Bank, MUFG Union Bank, N.A., Silicon Valley Bank, and SunTrust Robinson Humphrey Inc. acted as joint lead arrangers.
Use of Proceeds
We used $197,750 of the net available proceeds of the 2016 Credit Facility to retire all of the debt under our 2015 Credit Facility. We used $179,000 from our 2016 Credit Facility in connection with the acquisition of Nexmo on June 3, 2016. Remaining proceeds from the term note and the undrawn revolving credit facility under the 2016 Credit Facility will be used for general corporate purposes. We also incurred fees of $1,316 in connection with the 2016 Credit Facility, of which $395 was allocated to the term note and $921 was allocated to the revolving credit facility. The unamortized fees of $2,740 in connection with the 2015 Credit Facility were allocated as follows: $930 to the term note and $1,810 to the revolving credit facility. In adopting ASU 2015-03, fees allocated to the term note were reported in the balance sheet as a direct deduction from the face amount of the liability and in adopting ASU 2015-15, fees allocated to the revolving credit facility were reported in the balance sheet as an asset. These fees are amortized to interest expenses over the life of the debt using the effective interest method for the term note and straight line method for the revolving credit facility.
Repayments
In 2016, we made mandatory repayment of $14,062 under the term note. In addition, we repaid the $45,000 outstanding under the revolving credit facility.
2016 Credit Facility Terms
The following description summarizes the material terms of the 2016 Credit Facility:
The loans under the 2016 Credit Facility mature in June 2020. Principal amounts under the 2016 Credit Facility are repayable in quarterly installments of approximately $4,688 for the term note. The unused portion of our revolving credit facility incurs a 0.45% commitment fee. Such commitment fee will be reduced to 0.40% if our consolidated leverage ratio is greater than or equal to 1.50 to 1.00 and less than 2.50 to 1.00, 0.375% if our consolidated leverage ratio is greater than or equal to 0.75 to 1.00 and less than 1.50 to 1.00, and to 0.35% if our consolidated leverage ratio is less than 0.75 to 1.00.
Outstanding amounts under the 2016 Credit Facility, at our option, will bear interest at:
>LIBOR (applicable to one-, two-, three-, six-, or twelve-month periods) plus an applicable margin equal to 2.50% if our consolidated leverage ratio is less than 0.75 to 1.00, 2.75% if our consolidated leverage ratio is greater than or equal to 0.75 to 1.00 and less than 1.50 to 1.00, 3.00% if our consolidated leverage ratio is greater than or equal to 1.50 to 1.00 and less than 2.5 to 1.00, and 3.25% if our consolidated leverage ratio is greater than or equal to 2.50 to 1.00, payable
on the last day of each relevant interest period or, if the interest period is longer than three months, each day that is three months after the first day of the interest period, or
>the base rate determined by reference to the highest of (a) the prime rate of JPMorgan Chase Bank, N.A., (b) the federal funds effective rate from time to time plus 0.50%, and (c) the adjusted LIBO rate applicable to one month interest periods plus 1.00%, plus an applicable margin equal to 1.50% if our consolidated leverage ratio is less than 0.75 to 1.00, 1.75% if our consolidated leverage ratio is greater than or equal to 0.75 to 1.00 and less than 1.50 to 1.00, 2.00% if our consolidated leverage ratio is greater than or equal to 1.50 to 1.00 and less than 2.50 to 1.00, and 2.25% if our consolidated leverage ratio is greater than or equal to 2.5 to 1.00, payable on the last business day of each March, June, September, and December and the maturity date of the 2016 Credit Facility.
The 2016 Credit Facility provides greater flexibility to us in funding acquisitions and restricted payments, such as stock buybacks, than did the 2015 Credit Facility.
We may prepay the 2016 Credit Facility at our option at any time without premium or penalty. The 2016 Credit Facility is subject to mandatory prepayments in amounts equal to:
>100% of the net cash proceeds from any non-ordinary course sale or other disposition of our property and assets for consideration in excess of a certain amount subject to customary reinvestment provisions and certain other exceptions and
>100% of the net cash proceeds received in connection with other non-ordinary course transactions, including insurance proceeds not otherwise applied to the relevant insurance loss.
Subject to certain restrictions and exceptions, the 2016 Credit Facility permits us to obtain one or more incremental term notes and/or revolving credit facilities in an aggregate principal amount of up to $100,000 plus an amount equal to repayments of the term note upon providing documentation reasonably satisfactory to the administrative agent. The 2016 Credit Facility includes customary representations and warranties and affirmative covenants of the borrowers. In addition, the 2016 Credit Facility contains customary negative covenants, including, among other things, restrictions on the ability of us and our subsidiaries to consolidate or merge, create liens, incur additional indebtedness, dispose of assets, consummate acquisitions, make investments, and pay dividends and other distributions. We must also comply with the following financial covenants:
>a consolidated leverage ratio of no greater than 3.25 to 1.00 as of the end of the fiscal quarter ending June 30, 2016 and for each of the three consecutive fiscal quarters ending immediately thereafter; and a consolidated leverage ratio of no less than 2.75 to 1.00 as of the end of any fiscal quarter, commencing with the fiscal quarter ending June 30, 2017, with a limited step-up to 3.25 to 1.00 for a period of four consecutive quarters, in connection with an acquisition;
>a consolidated fixed coverage charge ratio of no less than 1.75 to 1.00 subject to adjustment to exclude up to $80,000 million in specified restricted payments;
>minimum cash of $25,000 including the unused portion of the revolving credit facility; and
>maximum capital expenditures not to exceed $55,000 during any fiscal year, provided that the unused amount of any permitted capital expenditures in any fiscal year may be carried forward to the next following fiscal year.
In addition, annual excess cash flow increases permitted capital expenditures.
As of December 31, 2016, we were in compliance with all covenants, including financial covenants, for the 2016 Credit Facility.
The 2016 Credit Facility contains customary events of default that may permit acceleration of the debt. During the continuance of a payment default, interest will accrue on overdue amounts at a default

These fees are amortized to interest expenses over the life of the debt using the effective interest method for the term note and straight line method for the revolving credit facility.

2014 Financing
On August 13, 2014, we entered into a credit agreement (the “2014 Credit Facility”) consisting of a $100,000 term note and a $125,000 revolving credit facility. The co-borrowers under the 2014 Credit Facility were us and Vonage America Inc., our wholly owned subsidiary.

with the unamortized fees of $668 in connection with the 2013 Credit Facility, to interest expense over the life of the debt using the effective interest method.
State and Local Sales Taxes
We also have contingent liabilities for state and local sales taxes. As of December 31, 2016,2018, we had a reserve of $1,763.$3,302. If our ultimate liability exceeds this amount, it could affect our liquidity unfavorably. However, we currently do not believe that these contingent liabilitiesit will significantly impair our liquidity.
Capital expendituresExpenditures
For 2016,the year ended December 31, 2018, capital expenditures were primarily for the implementation of software solutions and purchase of network equipment as we continue to expand our network. Our capital expenditures for the year ended 2016December 31, 2018 were $37,734,$26,746, of which $11,538$7,714 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 2017,2019, we believe our capital and software expenditures will be approximately $40,000. This amount is net

SUMMARY OF CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The preparation of consolidated financial statements in conformity with U.S. GAAP requires estimates and assumptions that affect the reported amounts and classifications of assets and liabilities, revenues and expenses, and the related disclosures of contingent liabilities in the consolidated financial statements and accompanying notes. The SEC has defined critical accounting policies as those policies management believes are most important to the portrayal of the Company's financial condition and results of operation and which require the Company to make its most difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. Based on this definition, the Company has identified the following critical accounting policies and estimated addressed below. Our significant accounting policies are summarized in Note 12, Summary of Significant Accounting Policies to our consolidated financial statements.Consolidated Financial Statements. The following describes our critical accounting policies and estimates:

Principles of Consolidation
The consolidated financial statements include the accounts of Vonage and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. We also

consolidated a majority-owned entity in Brazil where we had the ability to exercise controlling influence. The ownership interest of the noncontrolling party was presented as noncontrolling interest. On March 31, 2015, the Company completed its previously announced exit from the Brazilian market for consumer telephony services and the associated wind down of its joint venture operations in the country. The results of Brazilian operations are presented as discontinued operations for all periods presented. The results of companies acquired or disposed of are included in the consolidated financial statements from the effective date of the acquisition or up to the date of disposal.
Use of Estimates
Our 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 consolidated financial statements and the accompanying notes. Actual results could differ materially from these estimates.
On an ongoing basis, we evaluate our estimates, including the following:
>the useful lives of property and equipment, software costs, and intangible assets;
>assumptions used for the purpose of determining share-based compensation using the Black-Scholes option pricing model and Monte Carlo simulation model (“Models”), and various other assumptions that we believe to be reasonable; the key inputs for these Models include our stock price at valuation date, exercise price, the dividend yield, risk-free interest rate, life in years, and historical volatility of our common stock;
>assumptions used in determining the need for, and amount of, a valuation allowance on net deferred tax assets, and;
>assumptions used in determining the contingent consideration in connection with the Nexmo acquisition.
41     VONAGE ANNUAL REPORT 2018



We base our estimates on historical experience, available market information, appropriate valuation methodologies, and on various other assumptions that we believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Estimates are used for such items as depreciable lives for long-lived assets including intangible assets, tax provisions, uncollectible accounts, and assets and liabilities assumed in business combinations, among others. In addition, estimates are used to test long-lived assets and goodwill for impairment.
Revenue Recognition
OperatingOn January 1, 2018, the Company adopted the guidance of ASC Topic 606, Revenue from Contracts with Customers using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Our results for reporting periods beginning after January 1, 2018 are presented in accordance with the provisions under Topic 606 but any prior period amounts have not been adjusted.
Upon our adoption of Topic 606, we measure revenue based upon consideration specified by contracts with our customers. Revenue is recognized when our performance obligation under the contract is satisfied by transferring control over the product or service to the customer. We derive our revenues consistfor our Consumer and Business segments primarily from the sale of our communication services revenues and customer equipment (which enablesas further described below. The majority of the Company's contracts with customers have a single performance obligation for service revenues. We recognize revenue with customers when control transfers, which occurs upon delivery of a service or product. For our services) and shipping revenues. The point in time at which revenues are recognized is determined in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 104, Revenue Recognition, and Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605, Revenue Recognition.
AtBusiness segment, the timetypical life of a customer signs up for our services, there areservice is six years. The adoption of Topic 606 did not result in a change in the following deliverables:

We recordhow the fees collected for shipping the equipment to the customer, if any, as shipping and handling revenue at the time of shipment.Company recognizes revenue.
Services RevenueService Revenues
Substantially all of our revenues are servicesservice revenues, which are derived primarily from monthly subscription fees thatunder usage based or pay-per-use type billing arrangements, and contract-based services plans. For consumer customers are
charged under ourin the United States, we offer domestic and international rate plans, including a variety of residential plans and mobile plans. For business customers, we offer small and medium business, mid-market, and enterprise customers several service plans.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 a monthly fee. Customers also have the opportunity to purchase premium features for additional fees. We also derive servicesservice revenues from per minute fees for international calls if not covered under a plan, including calls made via applications for mobile devices and other stand-alone products, and for any calling minutes in excess of a customer’scustomer's monthly plan limits. MonthlyFor a portion of our customers, monthly subscription fees are automatically charged to customers’customers' credit cards, debit cards or electronic check payments ("ECP"), in advance and are recognized over the following month as service is provided.
Service revenue also includes supplying messaging (SMS and Voice) services to customers as part of our CPaaS offerings. Revenue is recognized in the period when servicesmessages are provided. Revenues generated from international calls and from customers exceeding allocated call minutes under limited minute plans are recognized as services are provided, that is, as minutes are used, and are billed to a customer's credit cards, debit cards or ECP in arrears. As a result of multiple billing cycles each month, we estimatesent by the amount of revenues earned from international calls and from customers exceeding allocated call minutes under limited minute plans but not billed from the end of each billing cycle to the end of each reporting period and record these amounts as accounts receivable. These estimates are based primarily upon historical minutes and have been consistent with our actual results.

In the United States, we charge regulatory, compliance, E-911 and intellectual property-related fees on a monthly basis to defray costs and to cover taxes that we are charged by the suppliers of telecommunications services. These charges, along with the remittance to the relevant government entity, are recorded on a net basis. In addition, we charge customers Federal Universal Service Fund (“USF”("USF") fees.fees from customers to recover our obligation to contribute to the fund, as allowed by the Federal Communications Commission ("FCC"). We recognize USF revenue on a gross basis for USF and record the related fees. We record these fees as revenue when billed. All other taxes are recorded on a net basis.
Our recently acquired subsidiary, Nexmo, provides CPaaS solutions to our customers. Through Nexmo, we provide innovative communication APIs for text messaging and voice communications, allowing developers and enterprises to embed contextual communications into mobile apps, websites and business workflows via text, social media, chat apps and voice. Nexmo has a global networkin cost of interconnected carriers delivering its API-based communications platform, enabling businesses to communicate with their customers reliably and with ease, no matter where in the world they are located.
Nexmo has two types of revenue activities:
Revenue is primarily derived from supplying messaging (SMS and Voice) services to customers. Revenue is recognized in the period when messages are sent by the customer. Revenue is recognized based on the price on the website pricing page or as otherwise agreed with the customer.
Our trading customers operate within the communications industry as service providers or bulk SMS aggregators. With our trading business, we sell to trading specialists who are delivering voice or SMS messages on behalf of their customers. Typically, trade is based on single supply route and margins, which are effectively fixed at a deal level, represent the value of the transaction to us. As such, for the trading business we record revenue on a net basis as service providers deliver messages. revenues.
Customer Equipment and Shipping RevenueRevenues
Customer equipment and shipping revenues consist of revenuesRevenues are generated from sales of customer equipment to wholesalers or 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.

Goodwill acquired in the acquisition of a business is accounted for based upon the excess fair value of consideration transferred over the fair value of netintangible assets acquired in the business combination. Goodwill isnot subject to amortization are tested for impairment on an annual basis on October 1st1st and, when specific circumstances dictate, between annual tests. When impaired,The Company tests for goodwill at the carrying valuereporting unit level, which is identified by assessing whether the components of the Company's operating segments constitute businesses for which discrete financial information is available. With respect to the annual goodwill is written down to fair value.impairment test on October 1st, the Company identified the UCaaS and CPaaS reporting units which collectively represent the Business segment as of that date. The goodwill impairment test involvespermits evaluating qualitative information to determine if it is more than 50% likely that the fair value of a reporting unit is less than its carrying value. If such a determination is made that it is more likely than not that the fair value of a reporting unit is less than its carrying value or if the Company chooses not to utilize a qualitative approach, then the traditional two-step goodwill impairment test described below must beis applied. The first step, identifying a potential impairment, compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying value of the reporting unit exceeds its fair value, the second step would need to be conducted; otherwise, no further steps are necessary as no potential impairment exists. The second step, measuring the impairment loss, compares the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. Any excess of the reporting unit goodwill carrying value over the respective implied fair value is recognized as an impairment loss. There
The Company performed step zero of the goodwill impairment test, performing its qualitative assessment of macroeconomic, industry and market events and circumstances, and the overall financial performance of the UCaaS and CPaaS reporting units as of October 1st. The Company determined it was not more likely than not that the fair value of the goodwill attributed each of the reporting units was less than its carrying amount and accordingly, no impairment of goodwillneeded to be recognized for the year ended December 31, 2016.2018. There were also no impairments recorded during the years ended December 31, 2017 and 2016, respectively.
Intangible assets acquired in the settlement of litigation or by direct purchase are accounted for based upon the fair value of assets received.
Purchased-intangible assets are accounted for based upon the fair value of assets received. Purchased-intangible assets are amortized on a straight-line or accelerated basis over the periods of benefit, ranging from two to ten years. We also perform a review of our purchased-intangible assets whenever events or changes in circumstances indicate that the useful life is shorter than we had originally estimated or that the carrying amount of assets may not be recoverable. If such facts and circumstances exist, we assess the recoverability of purchased-intangible assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairments, if any, are based on the excess of the carrying amount over the fair value of those assets. If the useful life of the asset is shorter than originally estimated, we accelerate the rate of amortization and amortize the remaining carrying value over the new shorter useful life. There was no impairment of purchased-intangible assets identified for the years ended December 31, 2016, 2015,2018, 2017, or 2014.2016.
Income Taxes
We recognize deferred tax assets and liabilities at enacted income tax rates for the temporary differences between the financial reporting bases and the tax bases of our assets and liabilities. Any effects of changes in income tax rates or tax laws are included in the provision for income taxes in the period of enactment. Our net deferred tax assetstaxes primarily consist of net operating loss carry forwards, (“NOLs”).or NOLs, intangibles and prepaids. We are required to record a valuation allowance against our net deferred tax assets if we conclude that it is more likely than not that taxable income generated in the future will be insufficient to utilize the future income tax benefit from our net deferred tax assets (namely, the NOLs) prior to expiration. We periodically review this conclusion, which requires significant management judgment. If we are able to conclude in a future period that a future income tax benefit from our net deferred tax assets has a greater than 50% likelihood of being realized, we are required in that period to reduce the related valuation allowance with a corresponding decrease in income tax expense. This would result in a
non-cash benefit to our net income in the period of the determination.We periodically review this conclusion, which requires significant management judgment. In the future, if available evidence changes our conclusion that it is more likely than not that we will utilize our net deferred tax assets prior to their expiration, we will make an adjustment to the related valuation allowance and income tax expense at that time. In subsequent periods, we would expect to recognize income tax expense equal to our pre-tax income multiplied by our effective income tax rate, an expense that was not recognized prior to the reduction of the valuation allowance.
Net Operating Loss Carryforwards
As of December 31, 2016,2018, we had NOLs for United States federal and state tax purposes, including thethose NOLs acquired as part of iCore, Simple Signal, Telesphere,past business combinations, of $578,522 and Vocalocity as of the date of acquisition, of $575,476 and $158,848,$245,403, respectively, expiring at various times from years ending 2017 through 2036.2037. In addition, we had NOLs for United Kingdom tax purposes of $43,006$162,535 with no expiration date.
Under Section 382 of the Internal Revenue Code, if we undergo an “ownership change” (generallywhich is generally defined as a greater than 50% change (by value)by value in our equity ownership over a three-year period),period, our ability to use our pre-change of control NOLs and other pre-change tax attributes against our post-change income may be limited. The Section 382 limitation is applied annually so as to limit the use of our pre-change NOLs to an amount that generally equals the value of our stock immediately before the ownership change multiplied by a designated federal long-term tax-exempt rate. At December 31, 2016,2018, there were no limitations on the use of our NOLs except for the NOLs of Vocalocity as of the date of acquisition.
Business Combinations
We accountacquisition for business combinations using the acquisition method of accounting. The acquisition method of accounting requires that the purchase price, including the fair value of contingent consideration, of the acquisition be allocated to the assets acquired and liabilities assumed using the fair values determined by management as of the acquisition date. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of assets acquired and the liabilities assumed. Whilewhich the Company uses its best estimates and assumptions as part ofhas reflected in the purchase price allocation process to accurately value assets acquired and liabilities assumed at the acquisition date, the Company’s estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill to the extent the Company identifies adjustments to the preliminary purchase price allocation. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations. We include the results of all acquisitions in our Consolidated Financial Statements from the date of acquisition.
Acquisition related transaction costs, such as banking, legal, accounting and other costs incurred in connection with an acquisition, are expensed as incurred in general and administrative expense.
Acquisition related integration costs include costs associated with exit or disposal activities, which do not meet the criteria of discontinued operations, including costs for employee, lease, and contract terminations, facility closing or other exit activities. Additionally, these costs include expenses directly related to integrating and reorganizing acquired businesses and include items such as employee retention costs, recruiting costs, certain moving costs, certain duplicative costs during integration and asset impairments. These costs are expensed as incurred in general and administrative expense.
Acquisition related consideration accounted for as compensation expense, such as restricted cash, restricted stock and option related costs incurred in connection with an acquisition are included in general and administrative expense.

Share-Based CompensationCapitalized Software
Capitalized costs include external consulting fees and payroll related cost for employees who are directly associated with, and who devote time to, the Company's internal-use software projects. Capitalization begins when the planning stage is complete, and continues during the application development stage. Capitalization ceases when the software has been tested and is ready for its intended use. Accordingly, internal and external costs incurred during the preliminary project stage, post implementation operation stage and ongoing maintenance are expensed as incurred. The Company amortizes completed internal-use software that is used on its network to expense over its estimated useful life.

In January 2017, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-04. "Intangibles - Goodwill and Other. 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. We are currently evaluating the impact of adopting ASU 2017-04 on our consolidated financial statements and related disclosures.
In December 2016, FASB issued ASU 2016-20, "Revenue from Contract with Customers - Technical Corrections and Improvements to Topic 606". In May 2016, FASB issued ASU 2016-12, "Revenue from Contract with Customers - Narrow-Scope Improvements and Practical Expedients". In April 2016, FASB issued ASU 2016-10, "Revenue from Contracts with Customers - Identifying Performance Obligations and Licensing". In March 2016, FASB issued ASU 2016-08, "Revenue from Contract with Customers - Principal versus Agent Considerations (Reporting Revenue Gross versus Net)". In August 2015, FASB issued ASU 2015-14, "Deferral of the Effective Date". In May 2014, FASB issued ASU 2014-09, "Revenue from Contracts with Customers". The core principle of these ASUs are that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments in ASU 2016-12 affect only the narrow aspects of the guidance, suchexpensed as assessing the collectibility criterion and accounting for contracts that do not meet the criterion, presentation of sales and other similar taxes collected from customers, non-cash consideration, and contract modifications at transition. ASU 2016-10 clarifies two aspects of the guidance: identifying performance obligations and the licensing implementation. The intention of the ASU 2016-08 is to improve the operability and understandability of the implementation guidance on principal versus agent considerations. ASU 2015-14 defers the effective date to annual and interim periods beginning on or after December 15, 2017, and early adoption will be permitted, but not earlier than the original effective date of annual and interim periods beginning on or after December 15, 2016, for public entities. ASU 2014-09 is a comprehensive new revenue recognition model for revenue from contract with customers. We will adopt these ASUs when effective. We are in the initial stages of evaluating the effect of adopting ASU2016-20, ASU 2016-12, ASU 2016-10, ASU 2016-08, ASU 2015-14, and ASU 2014-09 on our consolidated financial statements and related disclosures and continue to evaluate all transition methods.
In November 2016, FASB issued ASU 2016-18, "Statement of Cash Flows". This ASU requires that a statement of cash flows explains the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. As a result, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This ASU is effective for fiscal years beginning after December
15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. We will adopt this ASU in the first quarter of 2017. The adoption of ASU 2016-01 will not have a material impact on our consolidated financial statements and related disclosures.
In March 2016, FASB issued ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting". This ASU is issued as part of its Simplification Initiative. The areas for simplification in this ASU involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, recognition of share-based expense, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted for any entity in any interim or annual period. We will adopt this ASU in the first quarter of 2017. We will elect to account for forfeitures when they occur versus our current practice of estimating the number of awards that are expected to vest. The election of this new practice will result in a one-time adjustment to our accumulated deficit for the difference of the two practices through the end of 2016. The adoption of ASU 2016-09 will not have a material impact on our consolidated financial statements and related disclosures.
In February 2016, FASB issued ASU 2016-02, "Leases". This ASU increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted for all entities. The adoption of this ASU will increase assets and liabilities for operating leases. We are currently evaluating the impact of adopting ASU 2016-02 on our consolidated financial statements and related disclosures.
In January 2016, FASB issued ASU 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities". This ASU provide guidance concerning certain matters involving the recognition, measurement, and disclosure of financial assets and financial liabilities. The guidance does not alter the basic framework for classifying debt instruments held as financial assets. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is not permitted, with some exceptions. The adoption of ASU 2016-01 will not have a material impact on our consolidated financial statements and related disclosures.
In November 2015, FASB issued ASU 2015-17, "Balance Sheet Classification of Deferred Taxes". This ASU simplifies the presentation of deferred income taxes and requires deferred tax liabilities and assets be classified as non-current in a classified statement of financial position. This ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Earlier application is permitted for all entities as of the beginning of an interim or annual reporting period. Management has adopted ASU 2015-17 effective for the fourth quarter of 2016. We presented the net deferred tax assets as noncurrent, reclassified any current deferred tax assetsincurred in the consolidated balance sheet on a prospective basis, and we did not adjusted the prior periods. If the period ended December 31, 2015 was adjusted, the deferred income taxes would be a non-current deferred tax assets of $226,572
In July 2015, FASB issued ASU 2015-11, "Simplifying the Measurement of Inventory". This ASU applies to inventory that is measured using first-in, first-out ("FIFO") or average cost. Under the updated guidance, an entity should measure inventory that is within scope at the lower of cost and net realizable value, which isfinancial statements.  Significant judgments are used in determining the estimated selling pricesfair values assigned to the assets acquired and liabilities assumed and in determining estimates of useful lives of long-lived assets acquired. Estimates of the ordinary coursefair values of business, less reasonably predicable costs of completion, disposalassets acquired and transportation. Subsequent measurement is unchanged for inventory that is measured using last-in, first-out ("LIFO") or the retail inventory. This ASU is effective for annualliabilities assumed are based upon assumptions believed to be reasonable, and interim periods beginning after December 15, 2016, and should be applied prospectively with early adoption permitted at the beginning of an interim and annual reporting period. The adoption of ASU 2015-11 iswhen appropriate, include assistance from independent third-party appraisal firms.

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.

The foreign currency rate analysis assumed a uniform movement in currencies by 10% relative to the U.S. Dollar on our results. Based upon the results of this analysis, a 10% change in currency rates would have resulted in an increase or decrease in our earnings for the year ended December 31, 20162018 of approximately $1,400.$1.6 million.

ITEM 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures
  
Our management,Under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2016. The term “disclosure controls and procedures,” as defined in Rulespursuant to Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, (the “Exchange Act”),or the Exchange Act, as amended, meansas of the end of the period covered by this Annual Report on Form 10-K. Based on the evaluation of our disclosure controls and procedures as of December 31, 2018, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting
We have implemented significant phases of reporting and transaction system upgrades and are in initial stages of consolidating and upgrading additional transaction systems. Controls over installed and upgraded applications have not changed significantly but may in planned future phases of system and application implementations. There were no other changes to controls during the quarter ended December 31, 2018 that have materially affected or are reasonably likely to materially affect our internal control over financial reporting. 

Inherent Limitations over Internal Controls

The Company's controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Material Weakness.
In connection with the preparation of our consolidated financial statements as of and for the year ended December 31, 2016, we identified a material weakness in our internal control over financial reporting related to our controls over the preparation of the annual tax provision, described in Management’s Report on Internal Control Over Financial Reporting. We have concluded that this material weakness does not require a change in the fourth quarter or full year 2016 consolidated financial results disclosed in our Current Report on Form 8-K filed on February 14, 2017, nor does it require a restatement of or change in our consolidated financial statements for any prior annual or interim period. We have also developed a remediation plan for this material weakness, which is also described Management’s Report on Internal Control Over Financial Reporting.
Management’s Report on Internal Control Over Financial Reporting.Reporting
February 28, 201727, 2019
To the Stockholders of Vonage Holdings Corp.:
Our management is responsible for establishing and maintaining adequate internal control over financial reporting for the company. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, our principal executive and principal financial officers and effected by our board of directors, management, and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:
>
Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;
Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of our management and directors; and
>Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of our management and directors; and
>Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.
Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2016.2018. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013).
We completed the acquisition of Telefonica Digital Inc. and its subsidiaries, or Tokbox, on August 1, 2018 and the acquisition of NewVoiceMedia Limited and its subsidiaries, or NewVoiceMedia, on October 31, 2018. As part of our ongoing integration of TokBox and NewVoiceMedia we are continuing to incorporate our controls and procedures into these subsidiaries to augment our company-wide controls to reflect the risks inherent in these acquisitions. As permitted by the SEC guidance for newly acquired Nexmobusinesses, our Management Report over Internal Control over Financial Reporting for the year ended December 31, 2018 includes a scope exception that excludes TokBox and NewVoiceMedia in June 2016. Ourorder for management has excludedto have sufficient time to evaluate and implement our internal controls over the operations of these subsidiaries. These businesses from our evaluationrepresent 16% of and conclusion regarding, the effectiveness of our internal control over financial reporting as of December 31, 2016. This business represents 11% and 6% of our total assets and 1% of total revenues respectively,of the consolidated financial statement amounts as of and for the year ended December 31, 2016.2018. Our management plans to fully integrate the operations of these businesses into its assessment of the effectiveness of our internal controlcontrols over financial reporting in 2017.2019.
Based on our assessment, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2016,2018, our internal control over financial reporting was not effective, solely due to the material weakness in our internal control over financial reporting discussed below.effective.
In connection with the preparation of our consolidated financial statements as of and for the year ended December 31, 2016, we identified a material weakness in our internal control over financial reporting related to our controls over the preparation of the annual tax provision, described in Management’s Report on Internal Control Over Financial Reporting. This control deficiency resulted in a reclassification between goodwill and deferred tax assets, net in our annual financial statements as of and for the year ended December 31, 2016. While the control deficiency did not result in a misstatement of our previously issued consolidated financial statements, the deficiency constitutes a material weakness in our internal control over financial reporting due to the potential for the control deficiency to result in a material misstatement in our annual or interim consolidated financial statements that would not be prevented or detected.
Remediation Plan.
Management has begun implementing a remediation plan to address the control deficiency that led to the material weakness. The remediation plan includes (i) the implementation of additional review procedures designed to enhance our tax provision control and (ii) strengthening our tax provision control with improved documentation standards, oversight, and training.
We currently plan to have our enhanced review procedures and documentation standards in place and operating in the first quarter of 2017. Our goal is to remediate this material weakness by the end of 2017, subject to there being sufficient opportunities to conclude, through testing, that the enhanced control is operating effectively.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Stockholders of
Vonage Holdings Corp.
Holmdel, New Jersey 07733


Opinion on Internal Control over Financial Reporting
We have audited Vonage Holdings Corp.’s (the “Company”)the internal control over financial reporting of Vonage Holdings Corp. (the "Company") as of December 31, 2016,2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the “COSO criteria”)(COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2018, of the Company and our report dated February 27, 2019, expressed an unqualified opinion on those financial statements and included an explanatory paragraph regarding the adoption of new accounting standards.
As described in Management’s Report on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting at Telefonica Digital, Inc. and its subsidiaries (“Tokbox”) and NewVoiceMedia Limited and its subsidiaries (“NewVoiceMedia”), which were acquired on August 1, 2018 and October 31, 2018, respectively, and whose financial statements constituted 16% of total assets and 1% of total revenues of the consolidated financial statement amounts as of and for the year ended December 31, 2018. Accordingly, our audit did not include the internal control over financial reporting at Tokbox and NewVoiceMedia.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying “Item 9A. Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also includedrisk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. A material weakness regarding management’s failure to design and maintain controls over the preparation of the annual tax provision has been identified and described in management’s assessment. This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2016 financial statements, and this report does not affect our report dated February 28, 2017 on those financial statements.

As indicated in the accompanying Item 9A, Management’s Report on Internal Control over Financial Reporting”, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Nexmo Inc., which was acquired on June 3, 2016, and which is included in the consolidated balance sheets of Vonage Holdings Corp. as of December 31, 2016, and the related consolidated statements of income, comprehensive income, stockholders’ equity (deficit) and redeemable noncontrolling interest and cash flows for the year then ended. Nexmo constituted 11% of total assets as of December 31, 2016 and 6% of revenues for the year then ended. Management did not assess the effectiveness of internal control over financial reporting of Nexmo because of the timing of the acquisition. Our audit of internal control over financial reporting of Vonage Holdings Corp. also did not include an evaluation of the internal control over financial reporting of Nexmo.

In our opinion, Vonage Holdings Corp. did not maintain, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Vonage Holdings Corp. as of December 31, 2016 and 2015 and the related consolidated statements of income, comprehensive income, stockholders’ equity and redeemable noncontrolling interest, and cash flows for each of the three years in the period ended December 31, 2016 and our report dated February 28, 2017 expressed an unqualified opinion thereon.

SIGNIFICANT ACCOUNTING POLICIES
Note 2. Summary of Significant Accounting Policies

Principles of Consolidation
The consolidated financial statements have been prepared in accordance with U.S. GAAP. The Accounting Standards Codification, ASC, established by the Financial Accounting Standards Board, FASB, is the source of authoritative GAAP to be applied to nongovernmental entities. In addition, the rules and interpretive releases of the Securities and Exchange Commission, SEC, under the authority of federal securities laws are also sources of authoritative GAAP for SEC registrants.
The consolidated financial statements include the accounts and operations of Vonage and its wholly-owned subsidiaries.subsidiaries for which we have a controlling interest. All intercompany balances and transactions have been eliminated in consolidation. We also consolidatedThe usual condition for a majority-owned entity in Brazil where we had the ability to exercise controlling influence. Thefinancial interest is ownership interestof a majority of the noncontrolling party was presentedvoting interests of an entity; however, a controlling financial interest may also exist through arrangements that do not involve controlling voting interests. As such, Vonage applies the guidance of ASC 810, Consolidations, or ASC 810, to determine when an entity that is insufficiently capitalized or not controlled through its voting interests, referred to as noncontrolling interest. On March 31, 2015,a VIE, should be consolidated. In addition, the Company completed its previously announced exit from the Brazilian market for consumer telephony services and the associated wind down of its joint venture operations in the country. The results of Brazilian operations are presented as discontinued operations for all periods presented. The results of companies acquired or disposed of are included in the consolidated financial statements from the effective date of the acquisition or up to the date of disposal.
Use of Estimates
Our consolidated financial statements 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 consolidated financial statements and the accompanying notes. Actual results could differ materially from these estimates.Revenue Recognition
On an ongoing basis, we evaluate our estimates, includingJanuary 1, 2018, the following:Company adopted the guidance of ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)

assumptions used in determining the need for, and amount of, a valuation allowance on net deferred tax assets, and;

We base our estimates on historical experience, available market information, appropriate valuation methodologies, and on various other assumptions that we believed, or Topic 606, using the modified retrospective method applied to be reasonable, thethose contracts which were not completed as of January 1, 2018. Our results of which form the basis for making judgments about the carrying values of assets and liabilities.
Revenue Recognition
Operating revenues consist of services revenues and customer equipment (which enables our services) and shipping revenues. The point in time at which revenuesreporting periods beginning after January 1, 2018 are recognized is determinedpresented in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 104, Revenue Recognition, and Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605, Revenue Recognition.
At the time a customer signs up for our services, there are the following deliverables:
>
Providing equipment, if any, to the customer that enables our telephony services; and
>
Providing services.
The equipment is generally provided free of charge to our customers and in most instances there are no fees collected at sign-up. We record the fees collected for shipping the equipment to the customer, if any, as shipping and handling revenue at the time of shipment.
Services Revenue
Substantially all of our revenues are services revenues, which are derived primarily from monthly subscription fees that customers are chargedprovisions under our service plans. We also derive services revenues from per minute fees for international calls if not covered under a plan, including calls made via applications for mobile devices and other stand-alone products, and for any calling minutes in excess of a customer’s monthly plan limits. Monthly subscription fees are automatically charged to customers’ credit cards, debit cards or electronic check payments ("ECP"), in advance and are recognized over the following month when services are provided. Revenues generated from international calls and from customers exceeding allocated call minutes under limited minute plans are recognized as services are provided, that is, as minutes are used, and are billed to a customer's credit cards, debit cards or ECP in arrears. As a result of multiple billing cycles each month, we estimate the amount of revenues earned from international calls and from customers exceeding allocated call minutes under limited minute plans but not billed from the end of each billing cycle to the end of each reporting period and record these amounts as accounts receivable. These estimates are based primarily upon historical minutes and have been consistent with our actual results.Topic 606.

We also provide rebates to customers who purchase their customer equipment from retailers and satisfy minimum service period requirements. These rebates in excessUpon our adoption of activation fees are recorded as a reduction of revenues over the service periodTopic 606, we measure revenue based upon the estimated number of customers that will ultimately earn and claim the rebates.
In the United States, we charge regulatory, compliance, E-911, and intellectual property-related fees on a monthly basis to defray costs, and to cover taxes that we are chargedconsideration specified by the suppliers of telecommunications services. In addition, we charge customers Federal Universal Service Fund (“USF”) fees. We recognize revenue on a gross basis for USF and related fees. We record these fees as revenue when billed. All other taxes are recorded on a net basis.
Our recently acquired subsidiary, Nexmo, provides CPaaS solutions tocontracts with our customers. Through Nexmo, we provide innovative communication APIs for text messaging and voice communications, allowing developers and enterprises to embed contextual communications into mobile apps, websites and business workflows via text, social media, chat apps and voice. Nexmo has a global network of interconnected carriers delivering its API-based communications platform, enabling businesses to communicate with their customers reliably and with ease, no matter where in the world they are located.
Nexmo has two types of revenue activities:
Revenue is primarily derived from supplying messaging (SMS and Voice) services to customers. Revenue is recognized inwhen our performance obligation under the period when messages are sentcontract is satisfied by transferring control over the product or service to the customer. Revenue is recognized based on the price on the website pricing page or as otherwise agreed with the customer.
Our trading customers operate within the communications industry as service providers or bulk SMS aggregators. WithWe derive our trading business, we sell to trading specialists who are delivering voice or SMS messages on behalf of their customers. Typically, trade is based on single supply routerevenues for our Consumer and margins, which are effectively fixed at a deal level, represent the value of the transaction to us. As such, for the trading business we record revenue on a net basis as service providers deliver messages.
Customer Equipment and Shipping Revenue
Customer equipment and shipping revenues consist of revenues from sales of customer equipment to wholesalers or 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 revenuesBusiness segments primarily from the sale of VoIP telephones in order to access our smallcommunication services and medium business services. Customer equipment and shipping revenues also include the fees that customers are charged for shipping their customer equipment to them. Customer equipmentas further described in Note 3, Revenue Recognition. The majority of the Company's contracts with customers have a single performance obligation for service revenues. We recognize revenue with customers when control transfers, which occurs upon delivery of a service or product. For our Business segment, the typical life of a customer for service is six years. The adoption of Topic 606 did not result in a change in the timing of how the Company recognizes revenue.
Contract Acquisition Costs
We have various commission programs for which eligible employees and shipping revenues includethird parties may earn commission on sales to our retailers, who subsequently resell this customer equipmentof services and products to customers. RevenuesWe expect that these commission fees are reducedrecoverable and, therefore, we have capitalized these commissions as contract costs included within deferred customer acquisitions cost on our consolidated balance sheet. Capitalized commission fees are amortized to sales and marketing expense over estimated customer life, which is six years for paymentsBusiness customers. In addition, the Company expenses sales commissions for commission plans related to retailerscustomer arrangements deemed less than a year and rebates to customers, who purchased their customer equipment through these retailers, to the extent of customer equipmentfor residuals and shipping revenues.renewals.
Cost of ServicesRevenues
Cost of service consistsrevenues is primarily comprised of cost of services consisting of costs that we pay to third parties in order to provide services. These costs includesuch as access and interconnection charges that we pay to other companies to terminate domestic and international phone calls on the public switched telephone network. In addition, these costs include the cost to lease phone numbers, to co-locate in other companies’ facilities, to provide enhanced emergency dialing capabilities to transmit 911 calls, and to provide local number portability.portability are also included in cost of service. These costs also include taxes that we pay on telecommunications services from our suppliers or are imposed by government agencies such as federal universal service fund (“USF”)USF contributions and royalties for use of third parties’ intellectual property. In addition, these costs include certain personnel and related costs for
network operations and technical support that are attributable to revenue generating activities.

These costs include the cost ofincurred on customer equipment for customers who subscribe through the direct sales channel in excess of activation fees. In addition, these costs include theThe amortization of deferred customer equipment, the cost of shipping and handling for customer equipment, the installation manual that accompanies the customer equipment, and the cost of certain promotions.promotions are also included in cost of goods sold.

Costs for research, including predevelopment efforts prior to establishing technological feasibility of software expected to be marketed, are expensed as incurred.
Development costs are capitalized when technological feasibility has been established and anticipated future revenues support the recoverability of the capitalized amounts. Capitalization stops when the product is available for general release to customers. Due to the short time period between achieving technological feasibility and product release and the insignificant amount of costs incurred during such periods, we have not capitalized any software development, and have expensed these costs as incurred.
General and Administrative Expenses
General and administrative expenses primarily relate to our executive, finance, human resources, legal, and information technology organizations. General and administrative expenses primarily consist of personnel costs, stock compensation, board of directors' costs, professional fees for legal, accounting, tax, compliance and information systems, travel, recruiting expense and, rent and related expenses.
Advertising Expenses
Advertising costs are expensed as incurred.
Cash, Cash Equivalents and Marketable Securities

Certain Risks and Concentrations
Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash equivalents, marketable securities, and accounts receivable. They are subject to fluctuations in both market value and yield based upon changes in market conditions, including interest rates, liquidity, general economic conditions, and conditions specific to the issuers. Accounts receivable are typically unsecured and are derived from revenues earned from customers primarily located in the United States. A portion of our accounts receivable represents the timing difference between when a customer’s credit card is billed and the subsequent settlement of that transaction with our credit card processors. This timing difference is generally three days for substantially all of our credit card receivables. We have never experienced any accounts receivable write-offs due to this timing difference. In addition, we collect subscription fees in advance, minimizing our accounts receivable and bad debt exposure. If a customer’s credit card, debit card or ECP is declined, we generally suspend international calling capabilities as well as their ability to incur domestic usage charges in excess of their plan minutes. Generally, if the customer’s credit card, debit card or ECP could not be successfully processed during three billing cycles, (i.e., the current and two subsequent monthly billing cycles), we terminate the account. In addition, we automatically charge any per minute fees to our customers’ credit card, debit card or ECP monthly in arrears. To further mitigate our bad debt exposure, a customer’s credit card, debit card or ECP will be charged in advance of their monthly billing if their international calling or overage charges exceed a certain dollar threshold.
Inventory
Inventory consists of the cost of customer equipment and is statedvalued at the lower of cost or market, with cost determined using the average cost method. We provide an inventory allowance for customer equipment that has been returned by customers but may not be able to be reissued to new customers or returned to the manufacturer for credit.
Property and Equipment
Property and equipment includes acquired assets and those accounted for under capital leases and consist principally of network equipment and computer hardware, software, furniture, and leasehold improvements. Company-owned equipment in use at customer premises is also included in property and equipment. In addition, the lease of our corporate headquarters has been accounted for as a capital lease and is included in property and equipment. Network equipment, and computer hardware and furniture are stated at cost with depreciation provided using the straight-line method over the estimated useful lives of the related assets, which range from three to five years. Leasehold improvements are amortized over their estimated useful life of the related assets or the life of the lease, whichever is shorter. The cost of renewals and substantial improvements is capitalized while the cost of maintenance and repairs is charged to operating expenses as incurred. Company-owned customer premises equipment is depreciated on a straight-line basis over three years.
Our network equipment and computer hardware, which consists of routers, gateways, and servers that enable our telephony services, is subject to technological risks and rapid market changes due to new products and services and changing customer demand. These changes may result in future adjustments to the estimated useful lives or the carrying value of these assets, or both.
Software Costs

F-12     VONAGE ANNUAL REPORT 2018



VONAGE HOLDINGS CORP.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(In thousands, except per share amounts)


We capitalize certain costs, such as purchased software and internally developed software that we use for customer acquisition and customer care automation tools, in accordance with FASB ASC 350-40, “Internal-Use Software”Internal-Use Software. Computer software is stated at cost less accumulated amortization and the estimated useful life is two to five years.
Goodwill
In accordance with ASC 350, Intangibles - Goodwill acquired in the acquisition of a business is accountedand Other, we recognize goodwill for based upon the excess fair valuecost of consideration transferredan acquired business over the fair value of netassigned to assets acquired in the business combination.and liabilities assumed. Goodwill is tested for impairment on an annual basis on October 1st and, when specific circumstances dictate, between annual tests. When impaired, the carrying value of goodwill is written down to fair value. The goodwill impairment test involvespermits evaluating qualitative information to determine if it is more than 50% likely that the fair value of a reporting unit is less than its carrying value. If such a determination is made that it is more likely than not that the fair value of the reporting unit is less than its carrying value or if an entity chooses not to perform a qualitative assessment, then the traditional two-step goodwill impairment test described below must be applied. The first step, identifying a potential impairment, compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying value of the reporting unit exceeds its fair value, the second step would need to be conducted; otherwise, no further steps are necessary as no potential impairment exists. The second step, measuring the impairment loss, compares the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. Any excess of the reporting unit goodwill carrying value over the respective implied fair value is recognized as an impairment loss. There was no impairment of goodwill for the yearyears ended December 31, 2016, 2015,2018, 2017, and 2014.2016.
Intangible Assets
Intangible assets acquired in the settlement of litigation or by direct purchase are accounted for based upon the fair value of assets received.
Purchased-intangible assets are accounted for based upon the fair value of assets received. Purchased-intangible assetsreceived and are amortized on a straight-line or accelerated basis over the periods of economic benefit, ranging from two to tentwelve years. We perform a review of purchased-intangible assets whenever events or changes in circumstances indicate that the useful life is shorter than we had originally estimated or that the carrying amount of assets may not be recoverable. If such facts and circumstances exist, we assess the recoverability of purchased-intangible assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairments, if any, are based on the excess of the carrying amount over the fair value of those assets. If the useful life of the asset is shorter than originally estimated, we accelerate the rate of amortization and amortize the remaining carrying value over the new shorter useful life. There was no impairment of purchased-intangible assets identified for the years ended December 31, 2016, 2015,2018, 2017, and 2014.2016.
Patents and Patent LicensesAsset Impairments
Patent rights acquired in the settlement of litigation or by direct purchase are accounted for based upon the fair value of assets received.
Long-Lived Assets
We evaluate impairment losses on long-lived assets used in operations when events and changes in circumstances indicate that the assets might be impaired. If our review indicates that the carrying value of an asset will not be recoverable, based on a comparison of the carrying value of the asset to the undiscounted future cash flows, the impairment will be measured by comparing the carrying value of the asset to its fair value. Fair value will be determined based on quoted market values, discounted cash flows or appraisals. Impairments of property and equipment are recorded in the statement of incomeoperations as part of depreciation and amortization expense. There was no impairment of property and equipment identified for the years ended December 31, 2018, 2017, and 2016.
Debt Related Costs
Costs incurred in raising debt are deferred and amortized as interest expense using the effective interest method over the life of the debt. Costs associated with term loans are netted against the underlying notes payable in accordance with ASU 2015-15, "Interest-Imputation of Interest" while costs deferred associated with revolving facilities are included in other assets. Upon refinancing, costs associated with the new debt are either expensed or deferred and unamortized costs associated with the old debt are either written off or deferred and to be amortized as interest expense if deferred using the effective interest method over the life of the new debt per the guidance in ASC 470-50.
Restricted Cash and Letters of Credit
We had a cash collateralized letter of credit for $1,516 and $1,563 as of December 31, 2018 and 2017, respectively, mainly related to lease deposits for our Holmdel office. In the aggregate, cash reserves and collateralized letters of credit of $2,047 and $1,967 were recorded as long-term restricted cash at December 31, 2018 and 2017, respectively.

Debt Related CostsDerivative Financial Instruments
Costs incurred in raising debt are deferred and amortized as interest expense using the effective interest method over the life of the debt. A portion of these costs are netted against the underlying notes payable in accordance with ASU 2015-15, "Interest-Imputation of Interest".
Noncontrolling Interest and Redeemable Noncontrolling Interest
We consolidate a majority-owned entity where we have the ability to exercise controlling influence. The ownership interest of the noncontrolling party is presented as noncontrolling interest in the Consolidated Balance Sheet as Stockholders' Equity. If we are required to repurchase the noncontrolling interest at fair value, subject to adjustment, under a put option or other contractual redemption requirement, we will report the noncontrolling interest as redeemable in the Consolidated Balance Sheets between liabilities and equity. We adjust the redeemable noncontrolling interest to the redemption values on each balance sheet date with changes recognized as an adjustment to retained earnings, or in the absence of retained earnings, as an adjustment to additional paid-in capital when it becomes probable the noncontrolling interest will become redeemable.
Restricted Cash and Letters of Credit
We had a cash collateralized letter of creditCompany accounts for $1,578 and $2,498 as of December 31, 2016 and 2015, respectively, mainly related to lease deposits for our Holmdel office. In the aggregate, cash reserves and collateralized letters of credit of $1,851 and $2,587 were recorded as long-term restricted cash at December 31, 2016 and 2015, respectively.
Derivatives
We do not hold or issue derivative instruments for trading purposes. However, in accordance with FASB ASC 815, “Derivatives and Hedging” (“FASB ASC 815”), we review our contractual obligations to determine whether there are terms that possess the characteristics of derivative financial instruments that must be accounted for separately fromunder ASC 815, Derivatives and Hedging, which requires the financial instrument in which they are embedded. We recognize these features as liabilities in our consolidatedCompany to record all derivatives on the balance sheet at fair value each period and recognize any changeunless they qualify for a normal purchase normal sale exception. Changes in the fair value in our statement of operationsnon-hedge derivatives are immediately recognized into earnings. Changes in the period of change. We estimate the fair value of thesederivatives accounted for as hedges, if elected for hedge accounting, are either recognized in earnings as an offset to the changes in the fair value of the related hedged assets and liabilities using available market informationor deferred and appropriate valuation methodologies.recognized as a component of accumulated other comprehensive income, or OCI, until the hedged transactions occur and are recognized in earnings.
During 2017, the Company entered into three interest rate swap agreements to mitigate variability in our 2016 Credit Facility earnings due to fluctuations in interest rates and has been designated and qualified as a cash flow hedge. Upon the refinancing in 2018, the Company de-designated the swaps of our 2016 Credit Facility and re-designated the swaps as a cash flow hedge of the 2018 Credit Facility. As such, the balances in Accumulated Other Comprehensive Income related to de-designated 2016 Credit Facility cash flow hedge were either released into earnings or continue to be deferred and amortized over the remaining life of the 2018 Credit Facility. The Company assesses hedge effectiveness under the critical terms matched method at inception and at least quarterly through the life of the hedging relationship. If the critical terms of the interest rate swap match the terms of the forecasted transaction, the Company concludes that the hedge is effective.
Income Taxes
We recognize deferred tax assets and liabilities at enacted income tax rates for the temporary differences between the financial reporting bases and the tax bases of our assets and liabilities. Any effects of changes in income tax rates or tax laws are included in the provision for income taxes in the period of enactment. Our net deferred tax assets primarily consist of net operating loss carry forwards, (“NOLs”).or NOLs. We are required to record a valuation allowance against our net deferred tax assets if we conclude that it is more likely than not that taxable income generated in the future will be insufficient to utilize the future income tax benefit from our net deferred tax assets (namely, the NOLs) prior to expiration. We periodically review this conclusion, which requires significant management judgment. If we are able to conclude in a future period that a future income tax benefit from our net deferred tax assets has a greater than 50% likelihood of being realized, we are required in that period to reduce the related valuation allowance with a corresponding decrease in income tax expense. This would result in a non-cash benefit to our net income in the period of the determination. We periodically review this conclusion, which requires significant management judgment. In the future, if available evidence changes our conclusion that it is more likely than not that we will utilize our net deferred tax assets prior to their expiration, we will make an adjustment to the related valuation allowance and income tax expense at that time. In subsequent periods, we would expect to recognize income tax expense equal to our pre-tax income multiplied by our effective income tax rate,
an expense that was not recognized prior to the reduction of the valuation allowance. Our effective rate may differ from the federal statutory rate due, in part, to our foreign operations and certain discrete period items.
On December 22, 2017, the Tax Cuts and Jobs Act, or TCJA, was signed into law by the President of the United States. The TCJA most notably reduces the corporate tax rate from 35% to 21% along with eliminating the alternative minimum tax, or AMT, and imposing a mandatory one-time tax on foreign earnings. Under ASC 740, Income Taxes, an entity is required to recognize the effect of tax law changes during the period of enactment. As such, the Company will be reflecting the impact of this law within its December 31, 2017 financial statements. Due to the complexities of the new legislation and associated accounting considerations, SEC SAB 118 provided for an entity to utilize a provisional estimate within its financial statements for the impact of the TCJA. As permitted under SEC SAB 118, the Company recorded a provisional charge to income tax expense of $69,378 related to the re-measurement of the Company’s deferred tax balances at the 21% income tax rate in its December 31, 2017 statement of operations. The Company has determined that the provisional charge previously recorded in its December 31, 2017 financial statements is final and no further adjustments are required.
We file income tax returns in the U.S. on afor federal basisand state purposes and in U.S. state andvarious foreign jurisdictions. Our federal tax return remains subject to examination by the Internal Revenue Service from 20132015 to present, our New Jersey tax returns remain open from 20122014 to present, our Canada tax return remains open from 20142015 to present, and other domestic and foreign tax returns remain open for all periods to which those filings relate.

Business Combinations
We account for business combinations using the acquisition method of accounting. The acquisition method of accounting requires that the purchase price, including the fair value of contingent consideration, of the acquisition be allocated to the assets acquired and liabilities assumed using the fair values determined by management as of the acquisition date. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the acquisition date, the Company’s estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill to the extent the Company identifies adjustments to the preliminary purchase price allocation. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations. We include the results of all acquisitions in our Consolidated Financial Statementsconsolidated financial statements from the date of acquisition.
Acquisition related transaction costs, such as banking, legal, accounting and other costs incurred in connection with an acquisition, are expensed as incurred in general and administrative expense.
Acquisition related integration costs include costs associated with exit or disposal activities, which do not meet the criteria of discontinued operations, including costs for employee, lease, and contract terminations, facility closing or other exit activities. Additionally, these costs include expenses directly related to integrating and reorganizing acquired businesses and include items such as employee retention costs, recruiting costs, certain moving costs, certain duplicative costs during integration and asset impairments. These costs are expensed as incurred in general and administrative expense.
Acquisition related consideration accounted for as compensation expense, such as restricted cash, restricted stock and option related costs incurred in connection with an acquisition are included in general and administrative expense.

Foreign Currency
Generally, the functional currency of our non-United States subsidiaries is the local currency. However, the functional currency of Nexmo's United States's subsidiary is the euro.Euro. The financial statements of these subsidiaries are translated to United States dollarstheir respective functional currency using month-end rates of exchange for assets and liabilities, and average rates of exchange for revenues, costs, and expenses. Translation gains and losses from the Company's net investments in subsidiaries are deferred and recorded in accumulated other comprehensive income as a component of stockholders’ equity.equity until sale or complete or substantially complete liquidation of the net investment in the foreign entity takes place. Foreign currency transaction gains or losses are reported within other income/(expense), net in the Company's consolidated statements of operations. For the year ended December 31, 2018, the amount recognized as foreign currency transaction gain was $145 and for the years ended December 31, 2017 and 2016, amounts recognized as foreign currency transaction losses were $620 and $346, respectively.
Share-Based Compensation
We account for share-based compensation in accordance with FASB ASC 718, “Compensation-Stock Compensation”. Under the fair value recognition provisions of this pronouncement, share-based compensation cost is measured at the grant date based on the fair value of the award reduced as appropriate based on estimated forfeitures, and is recognized as expense over the applicable vesting period of the stock award on a straight-line basis. On January 1, 2017, the Company adopted ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting".  Previously, excess tax benefits were recognized in additional paid-in capital on the consolidated balance sheet to the extent they reduced income taxes payable.  Beginning in 2017, any excess tax benefits or shortfalls are recorded in income taxes upon vest or exercise.  During the years ended December 31, 2018 and 2017, the Company recorded a net benefit of $16 million and $11 million, respectively, related to excess tax benefits. 

Comprehensive Income (Loss)
Comprehensive income (loss) consists of net income (loss) and other comprehensive items. Other comprehensive items include unrealized gains (losses) on derivatives, foreign currency translation adjustments, and unrealized gains (losses) on available-for-sale securities.

Use of Estimates
Our consolidated financial statements 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 of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.
We base our estimates on historical experience, available market information, appropriate valuation methodologies, and on various other assumptions that we believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Estimates are used for such items as depreciable lives for long-lived assets including intangible assets, tax provisions, uncollectible accounts, and assets and liabilities assumed in business combinations, among others. In addition, estimates are used to test long-lived assets and goodwill for impairment.
Reclassifications
Reclassifications have been made to our consolidated financial statements for the prior year periods to conform to classification used in the current year period. The reclassifications did not affect results from operations or net assets.
Recent Accounting Pronouncements
In January 2017, the FASB issued Accounting Standards Update ("ASU") 2017-04, "Intangibles - Goodwill and Other". 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 have a material impact on our consolidated financial statements and related disclosures.
In February 2016, FASB issued ASU 2016-02, "Leases (Topic 842)". The new Accounting Standards Codification ("ASC") Topic 842 replaces existing 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. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted for all entities. FASB issued ASU 2018-10, “Codification Improvements to Topic 842, Leases” and ASU 2018-11, “Leases (Topic 842): Targeted Improvements” in July 2018, and ASU 2018-20, "Leases (Topic 842): Narrow-Scope Improvements for lessors" in December 2018, all of which affect narrow aspects of the guidance issued in ASU 2016-02. ASU 2018-11 provides an additional (and optional) transition method upon adoption of ASU 2016-02 to initially apply the new lease standard at the adoption date by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption in lieu of the comparative reporting initially required under ASU 2016-02 and ASU 2018-20 improves certain guidelines on lessor accounting.
The Company will adopt 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. In addition, we have elected the package of practical expedients permitted under the transition guidance which allows the Company to carry forward the historical lease classification. We have substantially completed our evaluation of impacts of Topic 842 on our financial statements and internal controls over financial reporting. The adoption of Topic 842 will have 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. On adoption, we expect to:
Recognize currently unrecognized right-of-use assets of approximately $55 million to $65 million.
Recognize currently unrecognized lease liabilities of approximately $60 million to $70 million (based on the present value of the remaining minimum rental payments for existing operating leases).
Recognize no adjustment to retained earnings.

The following standards were adopted by the Company during the current year:
In August 2018, FASB issued ASU 2018-15, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force)”. Under this ASU, a customer in a cloud computing arrangement that is a service contract would look to existing guidance for internal-use software under ASC 350-40 to determine whether implementation costs incurred under such arrangement may be capitalized and subsequently amortized over the periods covered under any applicable renewal options that are reasonably certain to be exercised. In addition, the guidance in this ASU also require the entity to present the expense related to the capitalized implementation costs in the same line item in the statement of income as the fees associated with the hosting element (service) of the arrangement and classify payments for capitalized implementation costs in the statement of cash flows in the same manner as payments made for fees associated with the hosting element. The entity is also required to present the capitalized implementation costs in the statement of financial position in the same line item that a prepayment for the fees of the associated hosting arrangement would be presented. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption of the amendments in this ASU is permitted, including adoption in any interim period. The amendments in this ASU should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company early adopted this ASU during the third quarter of 2018 on a retrospective basis and began capitalizing implementation costs associated with cloud computing arrangements entered into that are service contracts. The adoption of this ASU did not have a material impact on our consolidated financial statements and related disclosures.
In October 2016, FASB issued ASU 2016-16, "Income Taxes". This ASU improves the accounting for income tax consequences of intra-entity transfers of assets other than inventory. This ASU is effective for fiscal years beginning after December 15, 2017 on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. We adopted this ASU on January 1, 2018 and the adoption of this ASU did not have a material impact on our consolidated financial statements and related disclosures.
In August 2016, FASB issued ASU 2016-15, "Statement of Cash Flows". This ASU addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. This ASU is effective for fiscal years beginning after December 15, 2017 on a retrospective basis. Early adoption is permitted, including adoption in an interim period. We adopted this ASU on January 1, 2018 and the adoption of this ASU did not have a material impact on our consolidated financial statements and related disclosures.
In May 2014, FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)". This ASU, as amended, provided comprehensive guidance on the recognition of revenue from contracts with customers arising from the transfer of goods and services, guidance on accounting for certain contract costs and new disclosures. Topic 606 also amends the current guidance for the recognition of costs to obtain and fulfill contracts with customers requiring that all incremental costs of obtaining and direct costs of fulfilling contracts with customers such as commissions be deferred and recognized over the expected customer life. On January 1, 2018, we adopted this ASU. Refer to Note 3. Revenue Recognition for related disclosures required upon adoption.
In August 2017, FASB issued ASU 2017-12, "Derivatives and Hedging". The ASU improves the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements and simplifies the application of the hedge accounting guidance in current generally accepted accounting principles ("GAAP"). It also amends the disclosures requirements by requiring a tabular disclosure related to the effect on the statement of operations of fair value and cash flow hedges and eliminating the ineffective portion of the change in fair value of hedging instrument disclosures. This ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted in any interim period after issuance and is applied to hedging relationships existing on the date of adoption. We adopted ASU 2017-12 during the third quarter of 2018 and the adoption did not have a material impact on our consolidated financial statements and related disclosures.

Note 3.  Revenue Recognition

On January 1, 2018, the Company adopted the guidance of ASC Topic 606, Revenue from Contracts with Customersusing the accelerated method. The excess tax benefit associatedmodified retrospective method applied to those contracts which were not completed as of January 1, 2018. Our results for reporting periods beginning after January 1, 2018 are presented in accordance with stock compensation deductionsthe provisions under Topic 606 but any prior period amounts have not been adjusted and continue to be reported in accordance with our revenue recognition policy as further described in Note 2, Summary of Significant Accounting Policies. In connection with our adoption of Topic 606, we recognized a net increase to opening retained earnings of $24,848, net of tax, as of January 1, 2018 related to commissions paid associated with the acquisition of business customers and associated deferred tax liability.
Service Revenues
Substantially all of our revenues are service revenues, which are derived from monthly subscription fees under usage based or pay-per-use type billing arrangements, and contract-based services plans. For consumer customers in the United States, we offer domestic and international rate plans, including a variety of residential plans and mobile plans. For business customers, we offer small and medium business, 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 a monthly fee. Customers also have the opportunity to purchase premium features for additional fees. We also derive service revenues from per minute fees for international calls if not covered under a plan, including calls made via applications for mobile devices and other stand-alone products, and for any calling minutes in excess of a customer's monthly plan limits. For a portion of our customers, monthly subscription fees are automatically charged to customers' credit cards, debit cards or electronic check payments ("ECP"), in advance and are recognized over the following month as service is provided.
Service revenue also includes supplying messaging (SMS and Voice) services to customers as part of our CPaaS offerings. Revenue is recognized in the period when messages are sent by the customer. We also transact with providers or bulk SMS aggregators and sell services to these customers who then onsell to their customers. Since the aggregator is our customer, revenue is recognized on a gross basis with related costs included in cost of revenues.
In the United States, we charge regulatory, compliance, E-911 and intellectual property-related fees on a monthly basis to defray costs and to cover taxes that we are charged by the suppliers of telecommunications services. These charges, along with the remittance to the relevant government entity, are recorded on a net basis. In addition, we charge customers Federal Universal Service Fund ("USF") fees from customers to recover our obligation to contribute to the fund, as allowed by the Federal Communications Commission ("FCC"). We recognize USF revenue on a gross basis and record the related fees in cost of revenues.
Customer Equipment and Shipping Revenues
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 paid-in capital. When evaluating whether an excess tax benefit has been realized,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.

During the year ended December 31, 2018, the Company recognized revenue of $445,547 related to its contract liabilities. We expect to recognize $53,447 into revenue over the next twelve months related to our deferred revenue as of December 31, 2018.
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 $49,636 (net of accumulated amortization) and $34,484 as contract costs as of December 31, 2018 and January 1, 2018, respectively, included within deferred customer acquisitions costs, current and deferred customer acquisition costs on our consolidated balance sheet. In addition, we established a deferred tax liability associated with the transition asset of $9,636. Capitalized commission fees are amortized to sales and marketing expense over the estimated customer life, which is six years for Business customers. During the year ended December 31, 2018, the amounts amortized to sales and marketing were $10,287 and there were no longer sufficientimpairment losses recognized in relation to offset taxable income.

Note 4. Earnings Per Share

Earnings per Share
Net income(loss) per share has been computed according to FASB ASC 260, “Earnings per Share”, which requires a dual presentation of basic and diluted earnings per share, (“EPS”).or EPS. Basic EPS represents net income or loss divided by the weighted average number of common shares outstanding during a reporting period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock, including stock options and restricted stock units under our 2001 Stock Incentive Plan and 2006 Incentive Plan were exercised or converted into common stock. The dilutive effect of outstanding, stock options and restricted stock units is reflected in diluted earnings per share by application of the treasury stock method. In applying the treasury stock method for stock-based compensation arrangements, the assumed proceeds are computed as the sum of the amount the employee must pay upon exercise and the amounts of average unrecognized compensation cost attributed to future services.

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. We are currently evaluating the impact of adopting ASU 2017-04 on our consolidated financial statements and related disclosures.
In December 2016, FASB issued ASU 2016-20, "Revenue from Contract with Customers - Technical Corrections and Improvements to Topic 606". In May 2016, FASB issued ASU 2016-12, "Revenue from Contract with Customers - Narrow-Scope Improvements and Practical Expedients". In April 2016, FASB issued ASU 2016-10, "Revenue from Contracts with Customers - Identifying Performance Obligations and Licensing". In March 2016, FASB issued ASU 2016-08, "Revenue from Contract with Customers - Principal versus Agent Considerations (Reporting Revenue Gross versus Net)". In August 2015, FASB issued ASU 2015-14, "Deferral of the Effective Date". In May 2014, FASB issued ASU 2014-09, "Revenue from Contracts with Customers". The core principle of these ASUs are that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments in ASU 2016-12 affect only the narrow aspects of the guidance, such as assessing the collectibility criterion and accounting for contracts that do not meet the criterion, presentation of sales and other similar taxes collected from customers, non-cash consideration, and contract modifications at transition. ASU 2016-10 clarifies two aspects of the guidance: identifying performance obligations and the licensing implementation. The intention of the ASU 2016-08 is to improve the operability and understandability of the implementation guidance on principal versus agent considerations. ASU 2015-14 defers the effective date to annual and interim periods beginning on or after December 15, 2017, and early adoption will be permitted, but not earlier than the original effective date of annual and interim periods beginning on or after December 15, 2016, for public entities. ASU 2014-09 is a comprehensive new revenue recognition model for revenue from contract with customers. We will adopt these ASUs when effective. We are in the initial stages of evaluating the effect of adopting ASU2016-20, ASU 2016-12, ASU 2016-10, ASU 2016-08, ASU 2015-14, and ASU 2014-09 on our consolidated financial statements and related disclosures and continue to evaluate all transition methods.
In November 2016, FASB issued ASU 2016-18, "Statement of Cash Flows". This ASU requires that a statement of cash flows explains the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. As a result, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. We will adopt this ASU in the first quarter of 2017. The adoption of ASU 2016-01 will not have a material impact on our consolidated financial statements and related disclosures.
In March 2016, FASB issued ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting". This ASU is issued as part of its Simplification Initiative. The areas for simplification in this ASU involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, recognition of share-based expense, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted for any entity in any interim or annual period. We will adopt this ASU in the first quarter of 2017. We will elect to account for forfeitures when they occur versus our current practice of estimating the number of awards
that are expected to vest. The election of this new practice will result in a one-time adjustment to our accumulated deficit for the difference of the two practices through the end of 2016. The adoption of ASU 2016-09 will not have a material impact on our consolidated financial statements and related disclosures.
In February 2016, FASB issued ASU 2016-02, "Leases". This ASU increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. This ASU is effective for fiscal years beginning after December 15, 2018 including interim periods within those fiscal years. Early adoption is permitted for all entities. The adoption of this ASU will increase assets and liabilities for operating leases. We are currently evaluating the impact of adopting ASU 2016-02 on our consolidated financial statements and related disclosures.
In January 2016, FASB issued ASU 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities". This ASU provide guidance concerning certain matters involving the recognition, measurement, and disclosure of financial assets and financial liabilities. The guidance does not alter the basic framework for classifying debt instruments held as financial assets. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is not permitted, with some exceptions. The adoption of ASU 2016-01 will not have a material impact on our consolidated financial statements and related disclosures.
In November 2015, FASB issued ASU 2015-17, "Balance Sheet Classification of Deferred Taxes". This ASU simplifies the presentation of deferred income taxes and requires deferred tax liabilities and assets be classified as non-current in a classified statement of financial position. This ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Earlier application is permitted for all entities as of the beginning of an interim or annual reporting period. Management has adopted ASU 2015-17 effective for the fourth quarter of 2016. We presented the net deferred tax assets as noncurrent, reclassified any current deferred tax assets in the consolidated balance sheet on a prospective basis, and we did not adjusted the prior periods. If the period ended December 31, 2015 was adjusted, the deferred income taxes would be a non-current deferred tax assets of $226,572.
In July 2015, FASB issued ASU 2015-11, "Simplifying the Measurement of Inventory". This ASU applies to inventory that is measured using first-in, first-out ("FIFO") or average cost. Under the updated guidance, an entity should measure inventory that is within scope at the lower of cost and net realizable value, which is the estimated selling prices in the ordinary course of business, less reasonably predicable costs of completion, disposal and transportation. Subsequent measurement is unchanged for inventory that is measured using last-in, first-out ("LIFO") or the retail inventory. This ASU is effective for annual and interim periods beginning after December 15, 2016, and should be applied prospectively with early adoption permitted at the beginning of an interim and annual reporting period. The adoption of ASU 2015-11 is not expected to have a material impact on our consolidated financial statements and related disclosures.

For the year ended December 31, 2018, the Company's overall effective tax rate was different from the statutory rate of 21% primarily as a result of the increase in the state provision along with the permanent benefit related to the equity-based stock compensation and its related state impact.
For the year ended December 31, 2017, the Company's overall effective tax rate was different from the statutory rate of 35% primarily due to the impact of tax reform enacted in the United States on December 22, 2017 reducing the corporate tax rate from 35% to 21% beginning January 1, 2018. This resulted in an expense of $69,378 attributable to the re-measurement of the Company's deferred tax assets as of December 31, 2017. Due to the complexities of the new legislation and associated accounting considerations, SEC SAB 118 provided for an entity to utilize a provisional estimate within its financial statements for the impact of the TCJA. The Company has determined that the provisional amounts recorded in its December 31, 2017 statement of operations are final and no further adjustment is required.
On January 1, 2017, the Company adopted ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting".  Previously, excess tax benefits net of shortfalls were recognized in additional paid-in capital on the consolidated balance sheet to the extent they reduced income taxes payable.  Beginning in 2017, any excess tax benefits or shortfalls were recorded in income tax expense upon vest or exercise.  During the years ended December 31, 2018 and 2017, the Company recorded a net benefit of $16 million and $11 million, respectively, related to excess tax benefits. 
For the year ended December 31, 2016, the Company's overall effective tax rate was different than the statutory rate of 35% primarily due to the permanent adjustment for the contingent consideration relating to the acquisition of Nexmo.

required to record a valuation allowance against our net deferred tax assets if we conclude that it is more likely than not that taxable income generated in the future will be insufficient to utilize the future income tax benefit from our net deferred tax assets (namely, the NOLs), prior to expiration. We periodically review this conclusion, which requires significant management judgment. Until the fourth quarter of 2011, we

recorded a valuation allowance fully against our net deferred tax assets. In 2011, we completed our first full year of taxable income and completed our budgetary process for periods subsequent to 2011, which anticipates continued taxable income in the future. Based upon these factors and our sustained profitable operating performance over the past three years excluding certain losses associated with our prior convertible notes and our December 2010 debt refinancing, our evaluation determined that the benefit resulting from our net deferred tax assets (namely, the NOLs), are likely to be realized prior to their expiration. Accordingly, we released the related valuation allowance against our United States federal and Canada net deferredDeferred tax assets and a portion of thevaluation allowance against our state net
Net deferred tax assets as certain NOLs may expire prior to utilization due to shorter utilization periods in certain states, resulting inbalance - As of December 31, 2018 and 2017, we recorded a one-time non-cash income tax benefit of $325,601 and a corresponding net deferred tax asset, net of $325,601 in the fourth quarter of 2011. We still maintain a full valuation allowance against ourof $102,560 and $110,892, respectively. The Company believes that the net operating losses related to its United Kingdom net deferred tax assets as we are unable to conclude that it is moresubsidiary Vonage Limited and certain U.S. states may not be realizable under a "more likely than not that some or all ofnot" measurement and as such, a valuation allowance has been established to reduce the related United Kingdom net deferred tax assets will be realized. asset accordingly.
In connection with the acquisition of Nexmo, we recorded a deferred tax liability of $37,507 related to the $101,770 of identified intangible assets that will be amortized for financial reporting purposes but not for tax purposes and a deferred tax asset of $7,686 related to NOLs.NOL carryforwards -
In connection with the acquisition of iCore, we recorded a deferred tax liability of $12,944related to the $38,064 of identified intangible assets that will be amortized for financial reporting purposes but not for tax purposes and a deferred tax asset of $4,457 related to NOLs.
In connection with the acquisition of Simple Signal, we recorded a deferred tax liability of $2,441 related to the $6,407 of identified intangible assets that will be amortized for financial reporting purposes but not for tax purposes and a deferred tax asset of $3,182 related to NOLs.
In connection with the acquisition of Telesphere, we recorded a deferred tax liability of $17,050 related to the $50,925 of identified intangible assets that will be amortized for financial reporting purposes but not for tax purposes and a deferred tax asset of $17,101 related to NOLs.
In the future, if available evidence changes our conclusion that it is more likely than not that we will utilize our net deferred tax assets prior to their expiration, we will make an adjustment to the related valuation allowance and income tax expense at that time. In subsequent periods, we would expect to recognize income tax expense equal to our pre-tax income multiplied by our effective income tax rate, an expense that was not recognized prior to the reduction of the valuation allowance.

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 expenses incurred were $3,376, of which $474 was allocated to the term note and $2,813 was allocated to the revolving credit facility to 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. 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.

2018 Credit Facility Terms
The following description summarizes the material terms of the 2018 Credit Facility:
The loans under the 2018 Credit Facility mature on July 31, 2023. Principal amounts under the 2018 Credit Facility are repayable in quarterly installments of $2.5 million for the term loan. The unused portion of the Company's revolving credit facility incurs a 0.30% per annum commitment fee.
Outstanding amounts under the 2018 Credit Facility, at the Company's option, will bear interest at:
LIBOR (applicable to one-, two-, three-, six-, or twelve-month periods) plus an applicable margin equal to 2.00% up to 2.75% per annum payable on the last day of each relevant interest period or, if the interest period is longer than three months, each day that is three months after the first day of the interest period, or
the base rate determined by reference to the highest of (a) the rate of interest last quoted by the Wall Street Journal as the “Prime Rate” in the U.S., (b) the federal funds effective rate from time to time plus 0.50%, and (c) the adjusted LIBO rate applicable to one month interest periods plus 1.00%, plus an applicable margin equal to 1.00% up to 1.75% per annum payable on the last business day of each March, June, September, and December and the maturity date of the 2018 Credit Facility.

Use of Proceeds
We used $197,750 of the net available proceeds of the 2016 Credit Facility to retire all of the debt under our 2015 Credit Facility. We used $179,000 from our 2016 Credit Facility in connection with the acquisition of Nexmo on June 3, 2016. Remaining proceeds from the term note and the undrawn revolving credit facility under the 2016 Credit Facility will be used for general corporate purposes.

The unamortized fees of $2,740 in connection with the 2015 Credit Facility were allocated as follows: $930 to the term note and $1,810 to the revolving credit facility. In adopting ASU 2015-03, fees allocated to the term note were reported in the balance sheet as a direct deduction from the face amount of the liability and in adopting ASU 2015-15, fees allocated to the revolving credit facility were reported in the balance sheet as an asset. These fees are amortized to interest expenses over the life of the debt using the effective interest method for the term note and straight line method for the revolving credit facility.
Repayments
In 2016, we made mandatory repayment of $14,062 under the term note. In addition, we repaid the $45,000 outstanding under the revolving credit facility.

The loans under the 2016 Credit Facility mature in June 2020. Principal amounts under the 2016 Credit Facility are repayable in quarterly installments of approximately $4,688 for the term note. The unused portion of our revolving credit facility incurs a 0.45% commitment fee.

The 2016 Credit Facility provides greater flexibility to us in funding acquisitions and restricted payments, such as stock buybacks, than did the 2015 Credit Facility.
We may prepay the 2016 Credit Facility at our option at any time without premium or penalty. The 2016 Credit Facility is subject to mandatory prepayments in amounts equal to:
>100% of the net cash proceeds from any non-ordinary course sale or other disposition of our property and assets for consideration in excess of a certain amount subject to customary reinvestment provisions and certain other exceptions and
>100% of the net cash proceeds received in connection with other non-ordinary course transactions, including insurance proceeds not otherwise applied to the relevant insurance loss.
Subject to certain restrictions and exceptions, the 2016 Credit Facility permits us to obtain one or more incremental term notes and/or revolving credit facilities in an aggregate principal amount of up to $100,000 plus an amount equal to repayments of the term note upon providing documentation reasonably satisfactory to the administrative agent. The 2016 Credit Facility includes customary representations and warranties and affirmative covenants of the borrowers. In addition, the 2016 Credit Facility contains customary negative covenants, including, among other things, restrictions on the ability of us and our subsidiaries to consolidate or merge, create liens, incur additional indebtedness, dispose of assets, consummate acquisitions, make investments, and pay dividends and other distributions. We must also comply with the following financial covenants:

>a consolidated fixed coverage charge ratio of no less than 1.75 to 1.00 subject to adjustment to exclude up to $80,000 in specified restricted payments;
>minimum cash of $25,000 including the unused portion of the revolving credit facility; and
>maximum capital expenditures not to exceed $55,000 during any fiscal year, provided that the unused amount of any permitted capital expenditures in any fiscal year may be carried forward to the next following fiscal year.
In addition, annual excess cash flow increases permitted capital expenditures.
As of December 31, 2016, we were in compliance with all covenants, including financial covenants, for the 2016 Credit Facility.
The 2016 Credit Facility contains customary events of default that may permit acceleration of the debt. During the continuance of a payment default, interest will accrue on overdue amounts at a default interest rate of 2% above the interest rate which would otherwise be
applicable, in the case of loans, and at a rate equal to the rate applicable to base rate loans plus 2%, in the case of all other amounts.
2015 Financing
On July 27, 2015, we entered into a credit agreement (the “2015 Credit Facility”) consisting of a $100,000 term note and a $250,000 revolving credit facility.

Morgan Securities LLC, Citizens Bank, N.A., Fifth Third Bank, MUFG Union Bank, N.A., Silicon Valley Bank, and SunTrust Robinson Humphrey Inc. acted as joint lead arrangers.
Use of Proceeds
We used $167,000 of the net available proceeds of the 2015 Credit Facility to retire all of the debt under our 2014 Credit Facility. Remaining proceeds from the term note and the undrawn revolving credit facility under the 2015 Credit Facility were to be used for general corporate purposes. We also incurred fees of $2,007 in connection with the 2015 Credit Facility, of which $602 was allocated to the term note and $1,405 was allocated to the revolving credit facility. The unamortized fees of $1,628 in connection with the 2014 Credit Facility was allocated as follows: $733 to the term note and $895 revolving credit facility. In adopting ASU 2015-03, fees allocated to the term note were reported in the balance sheet as a direct deduction from the face amount of the liability and in adopting ASU 2015-15, fees allocated to the revolving credit facility were reported in the balance sheet as as asset. These fees are amortized to interest expenses over the life of the debt using the effective interest method for the term note and straight line method for the revolving credit facility. We used $82,000 from our 2015 revolving credit facility in connection with the acquisition of iCore on August 31, 2015.

We made mandatory repayments of $3,750 under the term note in 2016 and $7,500 under the term note in 2015. In addition, we repaid the $10,000 outstanding under the revolving credit facility in 2016 and $30,000 outstanding under the revolving credit facility in 2015.

2015 Credit Facility Terms

The loans under the 2015 Credit Facility were to mature in July 2019. Principal amounts under the 2015 Credit Facility were repayable in quarterly installments of $3,750 for the term note. The unused portion of our revolving credit facility incurred a 0.40% commitment fee. Such commitment fee would have been reduced to 0.375% if our consolidated leverage ratio was greater than or equal to 0.75 to 1.00 and less than 1.50 to 1.00 and to 0.35% if our consolidated leverage ratio was less than 0.75 to 1.00.

The 2015 Credit Facility provided greater flexibility to us in funding acquisitions and restricted payments, such as stock buybacks, than did the 2014 Credit Facility.
We were able to prepay the 2015 Credit Facility at our option at any time without premium or penalty. The 2015 Credit Facility was subject to mandatory prepayments in amounts equal to:
>100% of the net cash proceeds from any non-ordinary course sale or other disposition of our property and assets for consideration in excess of a certain amount subject to customary reinvestment provisions and certain other exceptions and
>100% of the net cash proceeds received in connection with other non-ordinary course transactions, including insurance proceeds not otherwise applied to the relevant insurance loss.
Subject to certain restrictions and exceptions, the 2015 Credit Facility permitted us to obtain one or more incremental term loans and/or revolving credit facilities in an aggregate principal amount of up to $90,000 plus an amount equal to repayments of the term note upon providing documentation reasonably satisfactory to the administrative agent. The 2015 Credit Facility included customary representations and warranties and affirmative covenants of the borrowers. In addition, the 2015 Credit Facility contained customary negative covenants, including, among other things, restrictions on the ability of us and our subsidiaries to consolidate or merge, create liens, incur additional indebtedness, dispose of assets, consummate acquisitions, make investments, and pay dividends and other distributions. We were also required to comply with the following financial covenants:
>a consolidated leverage ratio of no greater than 2.25 to 1.00, with a limited step-up to 2.75 to 1.00 for a period of four consecutive quarters, in connection with an acquisition made during the first two years of the 2015 Credit Facility;
>a consolidated fixed coverage charge ratio of no less than 1.75 to 1.00 subject to adjustment to exclude up to $80,000 million in specified restricted payments;
>minimum cash of $25,000 including the unused portion of the revolving credit facility; and
>maximum capital expenditures not to exceed $55,000 during any fiscal year, provided that the unused amount of any permitted capital expenditures in any fiscal year may be carried forward to the next following fiscal year.
In addition, annual excess cash flow increases permitted capital expenditures.
The 2015 Credit Facility contained customary events of default that permitted acceleration of the debt. During the continuance of a payment default, interest would have accrued on overdue amounts at a default interest rate of 2% above the interest rate which would otherwise be applicable, in the case of loans, and at a rate equal to the rate applicable to base rate loans plus 2%, in the case of all other amounts.
2014 Financing
On August 13, 2014, we entered into a credit agreement (the “2014 Credit Facility”) consisting of a $100,000 term note and a $125,000 revolving credit facility. The co-borrowers under the 2014 Credit Facility were us and Vonage America Inc., our wholly owned subsidiary. Obligations under the 2014 Credit Facility are guaranteed, fully and unconditionally, by our other material United States subsidiaries and were secured by substantially all of the assets of each borrower and each guarantor. The lenders under the 2014 Credit Facility were JPMorgan Chase Bank, N.A., Citizens Bank, N.A., Silicon Valley Bank, SunTrust Bank, Fifth Third Bank, Keybank National Association, and MUFG Union Bank, N.A. JPMorgan Chase Bank, N.A. was a party to the agreement as administrative agent, Citizens Bank, N.A. as syndication agent, and Silicon Valley Bank and SunTrust Bank as documentation agents. J.P. Morgan Securities LLC and Citizens Bank, N.A. acted as joint lead bookrunners, and J.P. Morgan Securities LLC, Citizens Bank, N.A., Silicon Valley Bank, and SunTrust Robinson Humphrey Inc. acted as joint lead arrangers.
Use of Proceeds
We used $90,000 of the net available proceeds of the 2014 Credit Facility to retire all of the debt under our 2013 Credit Facility. Remaining proceeds from the term note and the undrawn revolving credit facility under the 2014 Credit Facility were to be used for general corporate purposes. We also incurred $1,910 of fees in connection with the 2014 Credit Facility, which were amortized, along with the unamortized fees of $668 in connection with the 2013 Credit Facility, to interest expense over the life of the debt using the effective interest method. We used $20,000 and $67,000 from our 2014 revolving credit facility in connection with the acquisitions of Simple Signal on April 1, 2015 and Telesphere on December 15, 2014, respectively.
2014 Credit Facility Terms
The following description summarizes the material terms of the 2014 Credit Facility:
The loans under the 2014 Credit Facility were to mature in August 2018. Principal amounts under the 2014 Credit Facility were repayable in quarterly installments of $5,000 per quarter for the term note. The unused portion of our revolving credit facility incurred a 0.40% commitment fee.
Outstanding amounts under the 2014 Credit Facility, at our option, bore interest at:
>LIBOR (applicable to one-, two-, three-, six-, or twelve-month periods) plus an applicable margin equal to 2.875% if our consolidated leverage ratio is less than 0.75 to 1.00, 3.125% if our consolidated leverage ratio is greater than or equal to 0.75 to 1.00 and less than 1.50 to 1.00, and 3.375% if our consolidated leverage ratio is greater than or equal to 1.50 to 1.00, payable on the last day of each relevant interest period or, if the interest period is longer than three months, each day that is three months after the first day of the interest period, or
>the base rate determined by reference to the highest of (a)(b) the federal funds effective rate from time to time plus 0.50%, (b) the prime rate of JPMorgan Chase Bank, N.A., and (c) the adjusted LIBO rate applicable to one month interest periods plus 1.00%, plus an applicable margin equal to 1.875% if our consolidated leverage ratio is less than 0.75 to 1.00, 2.125% if our consolidated leverage ratio is greater than or equal to

Interest Rate Swap
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 2014swaps 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.
In connection with the $14 debt extinguishment, the Company reclassified a gain of $271 from accumulated other comprehensive income to earnings. The remaining $2,654 gain accumulated in other comprehensive income as of July 31, 2018 will be amortized over the term of the 2018 Credit Facility.

NOTE 7.8. Fair Value of Financial Instruments
Effective January 1, 2008, we adopted FASB ASC 820-10-25, “Fair Value Measurements and Disclosures”. This standard establishes a framework for measuring fair value and expands disclosure about fair value measurements. We did not elect fair value accounting for any assets and liabilities allowed by FASB ASC 825, “Financial Instruments”.
FASB ASC 820-10 defines fair value as the amount that would be received for an asset or paid to transfer a liability (i.e., an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. FASB ASC 820-10 also establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. FASB ASC 820-10 describes the following three levels of inputs that may be used:
>Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets and
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.
>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.  
Level 2: Observable prices that are based on inputs not quoted on active markets but corroborated by market data.
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.

Although management believed its valuation methods were appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could have resulted in a different fair value measurement at the reporting date.
The following table presents the assets and liabilities that are measured and recognized at fair value on a recurring basis classified under the appropriate level of the fair value hierarchy as of December 31, 20162018 and December 31, 2015:2017:

Ending balance$

Our contingent consideration liability is valued using a discounted cash flow valuation method encompassing significant unobservable inputs. The inputs include estimated revenue scenarios for the applicable performance periods, probability weightings assigned to revenue scenarios and the discount rate applied. Nexmo shareholders may earn a contingent consideration of up to $20,000, subject to the achievement of certain performance targets during the 12 month period following the closing of the transaction. The contingent consideration payable to the holders of Nexmo stock is determined based on (i) the achievement of certain revenue targets for the calendar year 2016, and (ii) Nexmo’s revenues received from its top customers following the closing. The contingent consideration may be in the form of cash, a number of shares of Vonage common stock or a combination thereof, at our sole discretion. We estimated using probability weighting that the value of the contingent consideration was $17,840 at the acquisition date and included that amount in acquisition cost at the net present value amount of $16,472. As of September 30, 2016, we have adjusted our probability weighting based upon updated information and have reduced the value of the contingent consideration to $9,866 with a net present value of $9,110. This reduction in the contingent consideration of $7,362 was recorded in general and administrative expenses. As of December 31, 2016, Nexmo did not achieve performance targets but
the parties have agreed to a $5,000 settlement that will be paid in the first quarter of 2017. As such we reduced the contingent consideration to $0 and recorded the reduction of the remaining net present value of $9,110 in general and administrative expenses. The $5,000 settlement has also been reflected in accrued expenses within the consolidated balance sheets and in general and administrative expenses in the consolidated statements of income.
Fair Value of Other Financial Instruments
The carrying amounts of our other financial instruments, including cash and cash equivalents, accounts receivable, and accounts payable, approximate fair value and are classified as Level 1 because of their short maturities. The carrying amounts of our capital leases approximate fair value of these obligations based upon management’s best estimates of interest rates that would be available for similar debt obligations at December 31, 2016 and 2015.2017. We believe the fair value of our debt at December 31, 2016 was2018 and December 31, 2017 were approximately the same as itstheir carrying amountamounts 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 debt2018 Credit Facility on July 31, 2018 and 2016 Credit Facility on June 3, 2016 for a similar debt instrument.instruments and are classified as Level 3 within the fair value hierarchy. 
As of December 31, 2018, we did not have any other assets or liabilities that are measured and recognized at fair value on a recurring basis.

 
Note 8.9. Common Stock
As of December 31, 2018 and December 31, 2017, the Company had 596,950 shares of common stock authorized. For a detailed description of our share-based compensation programs refer to Note 10, Employee Stock Benefit Plans.
Common Stock Repurchases
On December 9, 2014, Vonage's Board of Directors authorized a program for the Company to repurchase up to $100,000 of its outstanding common stock, or the 2014 $100,000 repurchase program. Repurchases under the 2014 $100,000 repurchase program were to be made over a four-year period and ended on December 31, 2018.

Net Operating Loss Rights Agreement
On June 7, 2012, we entered into a Tax Benefits Preservation Plan, ("or Preservation Plan")Plan, designed to preserve stockholder value and tax assets. Our ability to use our tax attributes to offset tax on U.S. taxable income would be substantially limited if there were an "ownership change" as defined under Section 382 of the U.S. Internal Revenue Code. In general, an ownership change would occur if one or more "5-percent shareholders," as defined under Section 382, collectively increase their ownership in us by more than 50 percent over a rolling three-year period.

(In thousands, except per share amounts)


In connection with the adoption of the Preservation Plan, our board of directors declared a dividend of one preferred share purchase right for each outstanding share of the Company’s common stock. The preferred share purchase rights were distributed to stockholders of record as of June 18, 2012, as well as to holders of the Company's common stock issued after that date, but will only be activated if certain triggering events under the Preservation Plan occur.
Under the Preservation Plan, preferred share purchase rights will work to impose significant dilution upon any person or group which acquires beneficial ownership of 4.9% or more of the outstanding common stock, without the approval of our board of directors, from and after June 7, 2012. Stockholders that own 4.9% or more of the outstanding common stock as of the opening of business on June 7, 2012, will not trigger the preferred share purchase rights so long as they do not (i) acquire additional shares of common stock or (ii) fall under 4.9% ownership of common stock and then re-acquire shares that in the aggregate equal 4.9% or more of the common stock.
The Preservation Plan was initially set to expire no later than the close of business June 7, 2013, unless extended by our board of directors. On June 6, 2013,8, 2017, at the Vonage 20132017 annual meeting of stockholders, stockholders ratified the extension of the Preservation
Plan through June 7, 2015. On April 2, 2015, after consultation with our advisors, our board of directors determined to extend the Preservation Plan through June 30, 2017, subject to ratification of the extension by stockholders at our 2015 annual meeting of stockholders. On June 3, 2015, at the Vonage 2015 annual meeting of stockholders, stockholders ratified thecontinued extension of the Preservation Plan through June 30, 2018.
Common Stock Repurchases
On July 25, 2012, our board of directors authorized a program to repurchase up to $50,000 of Vonage common stock (the "$50,000 repurchase program") through December 31, 2013. On February 7, 2013, our board of directors discontinued the remainder of our existing $50,000 repurchase program effective at the close of business on February 12, 2013 with $16,682 of availability remaining, and authorized a new program to repurchase up to $100,000 of Vonage common stock (the "2012 $100,000 repurchase program) by December 31, 2014. As of December 31, 2014, approximately $219 remained of our 2012 $100,000 repurchase program. The repurchase program expired on December 31, 2014.
On December 9, 2014, Vonage's Board of Directors authorized a new program for the Company to repurchase up to $100,000 of its outstanding common stock (the "2014 $100,000 repurchase program"). Repurchases under the 2014 $100,000 repurchase program program are expected to be made over a four-year period ending on December 31, 2018.
Under the 2014 $100,000 repurchase program, the timing and amount of repurchases will be determined by management based on its evaluation of market conditions, the trading price of the stock and will vary based on available capital resources and other financial and operational performance, market conditions, securities law limitations, and other factors. Repurchases may be made in the open market or through private transactions from time to time. The repurchases will be

Note 9.10. Employee Stock Benefit Plans
Share-Based Compensation
Our stock option program is a long-term retention program that is intended to attract, retain and provide incentives for talented employees, officers and directors, and to align stockholder and employee interests. Currently, we grant options from our 2015 Equity Incentive Plan. Our 2006 Stock Incentive Plan was terminated by our board of directors in 2015 and our 2001 Stock Incentive Plan was terminated by our board of directors in 2008. As such, share-based awards are no longer granted under either the 2006 Incentive Plan and the 2001 Stock
Incentive Plans.Plan. Under the 2015 Equity Incentive Plan, share-based awards can be granted to all employees, including executive officers, outside consultants, and non-employee directors. Vesting periods for share-based awards are generally three or four years for both plans. Awards granted under each plan expire in five or ten years from the effective date of grant. As of April 2010, the Company began routinely granting awards with a ten year expiration period.
The fair value for these options was estimated at the date of grant using a Black-Scholes option-pricing model. The company did not grant options in 2018. The assumptions used to value options arein 2017 and 2016 were as follows:

Beginning in the first quarter of 2008, we used the historical volatility of our common stock to measure expected volatility for future option grants.
The risk-free interest rate assumption is based upon observed interest rates appropriate for the term of our employee stock
options. The expected term of employee stock options represents the weighted-average period that the stock options are expected to remain outstanding, which we derive based on our historical settlement experience. As we historically have not paid dividends, we utilize a dividend yield of 0%.

2006 Incentive Plan
In May 2006, we adopted the 2006 Incentive Plan. The 2006 Incentive Plan permits the grant of stock options, restricted stock, restricted stock units, stock appreciation rights, performance stock, performance units, annual awards, and other awards based on, or related to, shares of our common stock. Options awarded under our 2006 Incentive Plan may be non-qualified stock options or may qualify as incentive stock options under Section 422 of the Internal Revenue Code of 1986, as amended. Our 2006 Incentive Plan contains various limits with respect to the types of awards, as follows:
a maximum of 20,000 shares may be issued under the plan pursuant to incentive stock options;
a maximum of 10,000 shares may be issued pursuant to options and stock appreciation rights granted to any participant in a calendar year;
a maximum of $5,000 may be paid pursuant to annual awards granted to any participant in a calendar year; and
a maximum of $10,000 may be paid (in the case of awards denominated in cash) and a maximum of 10,000 shares may be issued (in the case of awards denominated in shares) pursuant to awards, other than options, stock appreciation rights or annual awards, granted to any participant in a calendar year.
The 2006 Incentive Plan was terminated upon the adoption of our 2015 Equity Incentive Plan. No additional awards may be made pursuant to the 2006 Incentive Plan.
2015 Equity Incentive Plan
On June 3, 2015, we adopted our 2015 Equity Incentive Plan which replaced the 2006 Incentive Plan. Shares issued under the plan may be authorized and unissued shares or may be issued shares that we have reacquired. Shares covered by awards that are forfeited, canceled or otherwise expire without having been exercised or settled, or that are settled by cash or other non-share consideration, will become available for issuance pursuant to a new award. Shares that are tendered or withheld to pay the exercise price of an award or to satisfy tax withholding obligations will not be available for issuance pursuant to new awards.  Our 2015 Equity Incentive Plan will terminate on June 3, 2025. At December 31, 2016, 13,8412018, 7,227 shares were available for future grant under the 2015 Equity Incentive Plan.
The 2015 Equity Incentive Plan permits the grant of stock options, restricted stock, restricted stock units, stock appreciation rights, performance stock, performance units, annual awards, and other awards based on, or related to, shares of our common stock. Options awarded under our 2015 Equity Incentive Plan may be non-qualified stock options or may qualify as incentive stock options under Section 422 of the Internal Revenue Code of 1986, as amended. For purposes of complying with the requirements of Section 162(m) of the Internal Revenue Code of 1986, as amended, the maximum number of shares of common stock that may be subject to stock options, stock appreciation rights, performance-based restricted stock awards, performance-based RSUsrestricted stock units and performance-based stock awards granted to any participant other than a non-employee director during any calendar year will be limited to 10,000 shares of common stock for each such award type individually. The maximum number of shares of common stock that may be subject to stock options, stock appreciation rights, restricted stock awards, RSUsrestricted stock units and stock awards granted to any non-employee director during any calendar year will be limited to 10,000 shares of common stock for all such award types in the aggregate. Further, the maximum amount that may become payable to any one Participant during any one calendar year under all Cash Performance Awards intended to qualify as “performance-based compensation” under Section 162(m) of the Internal Revenue Code of 1986, as amended, is limited to $5,000.
Our 2015 Equity Incentive Plan will terminate on June 3, 2025.

Note 10.11. Commitments and Contingencies

Capital Leases
Assets financed under capital lease agreements are included in property and equipment in the consolidated balance sheet and related depreciation and amortization expense is included in the consolidated statements of operations.
On March 24, 2005, we entered into a lease for our headquarters in Holmdel, New Jersey. We took possession of a portion of the office space at the inception of the lease, another portion on August 1, 2005 and took over the remainder of the office space in early 2006. The overall lease term is twelve years and five months. In connection with the lease, we issued a letter of creditmonths, which requires $7,350 of cash as collateral, which is classified as restricted cash. Part of the cash was released, leaving a balance of $1,578 at Decemberended on August 31, 2016. The gross amount of the building recorded under capital leases totaled $25,709 as of December 31, 2016 and accumulated depreciation was approximately $24,243 as of December 31, 2016.
2017. In November 2015, we entered into the fourth amendment to our headquarters lease effective December 1, 2015. The amendment extendextends the term of the lease for a period of seventy-four months to commence September 1, 2017 and continue through October 31, 2023. Based on the terms of the lease, it is consideredwas accounted for as an operating lease when it becomesbecame effective on September 1, 2017.
Operating Leases
We have entered into various non-cancelable operating lease agreements for certain of our existing office and telecommunications co-location space in the United States and for international subsidiaries with original lease periods expiring between 2017 andthrough 2026.

We have stand-by letters of credit totaling $1,578$1,516 and $2,498,$1,563, as of December 31, 20162018 and 2015,2017, respectively.
End-User Commitments
We are obligated to provide telephone services to our registered end-users. The costs related to the potential utilization of minutes sold are expensed as incurred. Our obligation to provide this service is dependent on the proper functioning of systems controlled by third-party service providers. We do not have a contractual service relationship with some of these providers.
Vendor Commitments
We have several commitments primarily commitments to vendors who will provide local inbound services, provide customer care services, provide efax service, provide carrier operation, provide data center with technical supports, provide networks and telephone related services, provide marketing infrastructure and services, provide customer caller ID, provide hardware and software supports, provide web hosting service, provide electricity to our office, provide software maintenance service, and license patents to us, partner with us in international operations, process LNP orders, and lease office space to us. In certain cases, we may terminate these arrangements early upon payment of specified fees. These commitments total $203,273.$57,173. Of this total amount, we expect to purchase $86,048 in 2017, $84,959 in 2018, $19,553$32,177 in 2019, $2,000$10,873 in 2020, and$5,602 in 2021, and $8,713 thereafter,$4,976 in 2022 and $3,545 in 2023, respectively. These amounts do not represent our entire anticipated purchases in the future, but represent only those items for which we are contractually committed. We also purchase products and services as needed with no firm commitment. For this reason, the amounts presented do not provide a reliable indicator of our expected future cash outflows or changes in our expected cash position.
Litigation
From time to time, in addition to those identified below, 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 also 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 the abovematters noted mattersbelow 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.
IP Matters
Bear Creek Technologies, Inc. On February 22, 2011, Bear Creek Technologies, Inc. (“Bear Creek”) filed a lawsuit against Vonage Holdings Corp., Vonage America Inc., Vonage Marketing LLC, and Aptela Inc. (the latter two entities being former subsidiaries of Vonage Holdings Corp. now merged into Vonage America Inc. and Vonage Business Inc., respectively) in the United States District Court for the Eastern District of Virginia alleging that Vonage’s and Aptela’s products and services are covered by United States Patent No. 7,889,722, entitled “System for Interconnecting Standard Telephony Communications Equipment to Internet Protocol Networks” (the “'722 Patent”). The suit also named numerous other defendants. On August 17, 2011, the Court dismissed Bear Creek’s case against the Vonage entities and Aptela, and all but one of the other defendants. Later, on August 17, 2011, Bear Creek re-filed its complaint in the United States District Court for the District of Delaware against the same Vonage entities; and re-filed its complaint in the United States District Court for the Eastern District of Virginia against Aptela. On May 2, 2012, the litigations against Vonage and Aptela were consolidated for pretrial proceedings with twelve other actions in the District of Delaware. Vonage filed an answer to Bear Creek’s complaint, including counterclaims of non-infringement and invalidity of the ‘722 patent. Aptela, which filed a motion to dismiss Bear Creek’s complaint on September 27, 2011, has not yet answered, as its motion remains pending. On November 5, 2012, Bear Creek filed an answer to Vonage’s counterclaims. On July 17, 2013, the Court stayed the case pending resolution of the reexamination of the ‘722 patent requested by Cisco Systems, Inc. (“Cisco”), described below. On May

A request for reexamination of the validity of the ‘722 Patent was filed on September 12, 2012 by Cisco. Cisco’s request was granted on November 28, 2012. On March 24, 2014, the United States Patent and Trademark Office issued an Action Closing Prosecution, confirming its rejection of all claims of the ‘722 patent. Bear Creek’s November 14, 2014 appeal of that decision to the Patent Trial and Appeal Board was denied on December 29, 2015. Bear Creek appealed the Board’s decision to the United States Court of Appeals for the Federal Circuit. Briefing on the appeal is complete and pending oral argument before the Court on March 13, 2017.
RPost Holdings, Inc. On August 24, 2012, RPost Holdings, Inc., RPost Communications Limited, and RMail Limited (collectively, “RPost”) filed a lawsuit against StrongMail Systems, Inc.

On February 11, 2013, RPost filed an amended complaint, adding 27 new defendants, including Vonage America Inc. RPost’s amended complaint alleges willful infringement of the RPost patents by Vonage and each of the other new defendants because they are customers of StrongMail. StrongMail has agreed to fully defend and indemnify Vonage in this lawsuit. Vonage answered the complaint on May 7, 2013. On September 17, 2015, the Court ordered the consolidation for pre-trial purposes of this case with other cases by RPost. The lead case has been administratively closed and stayed since January 30, 2014 due to multiple pending actions by third parties regarding ownership of the patents at issue. On December 1, 2016, the parties in the consolidated actions filed a joint notice regarding status of the co-pending actions. Plaintiffs requested that the stay be lifted, while defendants maintain that the stay should remain in place. 
AIP Acquisition LLC. On January 3, 2014, AIP Acquisition LLC (“AIP”), filed a lawsuit against Vonage Holdings Corp., Vonage America, Inc., and Vonage Marketing LLC in the U.S. District Court for the District of Delaware alleging that Vonage’s products and services are covered by United States Patent No. 7,269,247. Vonage filed an answer and counterclaims on February 25, 2014. AIP filed an amended complaint on March 18, 2014, which Vonage answered on April 4, 2014. On April 8, 2014, the Court stayed the case pending final resolution of non-party Level 3’s inter partes review request of United States Patent No. 7,724,879, which is a continuation of the ‘247 patent. On October 8, 2014, the Patent Office issued a Final Written Decision, finding all challenged claims of the ‘879 patent to be invalid. On November 10, 2015, the Federal Circuit rejected AIP’s appeal and affirmed the Patent Office’s rejection of the ‘879 patent.
Cisco petitioned for inter partes review of the ‘247 patent on November 25, 2014, which was granted on May 20, 2015. On May 18, 2016, the Patent Office issued a Final Written Decision, finding all challenged claims of the ‘247 patent to be invalid. AIP appealed to the Federal Circuit, filing its opening brief on December 15, 2016. On December 20, 2016, the Patent Office filed a notice of intervention in the appellate proceedings. Both the Patent Office’s and Cisco’s responsive briefs are due on March 13, 2017.
Commercial Litigation
Merkin & Smith, et alsal.  On September 27, 2013, Arthur Merkin and James Smith filed a putative class action lawsuit against Vonage America, Inc. in the Superior Court of the State of California, County of Los Angeles, alleging that Vonage violated California’s Unfair Competition Law by charging its customers fictitious 911 taxes and fees. On October 30, 2013, Vonage filed a notice removing the case to the United States District Court for the Central District of California. On November 26, 2013, Vonage filed its Answer to the Complaint. On December 4, 2013, Vonage filed a Motion to Compel Arbitration, which the Court denied on February 4, 2014. On March 5,
2014, Vonage appealed that decision to the United States Court of Appeals for the Ninth Circuit. On March 26, 2014, the district court proceedings were stayed pending the appeal. On February 29, 2016, the Ninth Circuit reversed the district court’s ruling and remanded with instructions to grant the motion to compel arbitration. On March 22, 2016, Merkin and Smith filed a petition for rehearing. On May 4, 2016, the Ninth Circuit withdrew its February 29, 2016 decision and issued a new order reversing the district court’s order and remanded with instructions to compel arbitration. The Ninth Circuit also declared as moot the petition for rehearing. On June 27, 2016, the lower court stayed the case pending arbitration. A joint status report was filed with the District Court on December 23, 2016. A second joint status report was filed with the District Court on March 23, 2017. A third joint status report was filed with the District Court on June 27, 2017. A fourth joint status report was filed with the District Court on September 26, 2017. A fifth joint status report was filed with the District Court on December 26, 2017. Counsel for Vonage spoke with counsel for plaintiffs in mid-February 2018, seeking voluntary dismissal. In the fourth quarter of 2018, Vonage prepared a motion to dismiss. Following a meeting and confirmation regarding the motion to dismiss, the parties agreed to settle the matter and Plaintiff's counsel prepared a Stipulation for Dismissal. The United States District Court for the Central District of California dismissed the case without prejudice on February 21, 2019. The Company will discontinue reporting on this matter.
Regulation
Telephony services are subject to a broad spectrum of state, federal and federalforeign 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.
Federal - Net Neutrality
Clear and enforceableThe Company continues to monitor federal regulations relating to net neutrality, rules make it more difficult for broadband Internet service providers to block or discriminate against Vonage service. In addition, explicitly applying net neutrality rules to wireless broadband Internet service providers could create greater opportunities for VoIP applications that run on wireless broadband Internet service. In December 2010, the FCC adopted net neutrality rules that applied strong net neutrality rules to wired broadband Internet service providers and limited rules to wireless broadband Internet service providers. On January 14, 2014, the D.C. Circuit Court of Appeals vacated a significant portion of the 2010 rules. On May 15, 2014, the FCC issued a Notice of Proposed Rulemaking (NPRM) proposing new net neutrality rules. After public response to the NPRM, the FCC adopted new neutrality rules on February 26, 2015. These rules prohibit broadband Internet service providers from: (1) blocking or throttling lawful content applications, or services; (2) imposing paid prioritization arrangements; and (3) unreasonably interfering or unreasonably disadvantaging consumers or edge providers. In addition, broadband Internet service providers are required to make certain disclosures regarding their network management practices, network performance, and commercial terms. These net neutrality rules apply the same requirements to wired and wireless broadband Internet service providers. Several parties have filed appeals which are pending at the D.C. Circuit Court of Appeals. Oral arguments at the D.C. Circuit Court of Appeals were held on December 4, 2015. On June 14, 2016, the D.C. Circuit of Appeals denied the appeals. Several parties filed a petition for rehearing en banc on July 29, 2016. The petition is pending.
Federal - Lifeline Reform
On March 31, 2016, the FCC adopted an order modernizing the Lifeline program. The Lifeline program previously subsidized voice service for low-income customers and is one component of the federal universal service fund. The order refocuses the program to subsidize broadband. Increased adoption of broadband services expands the market for Vonage services. The order will also likely increase the overall size of the federal universal fund and lead to increased USF contribution levels for Vonage services subject to assessment for federal USF.
Federal - Rural Call Completion Issues
On February 7, 2013, the FCC released a Notice of Proposed Rulemaking (NPRM) on rural call completion issues. The NPRM proposed new detailed reporting requirements to gauge rural call

(In thousands, except per share amounts)


completion performance. Rural carriers have argued that VoIP provider call completion performance to rural areas is generally poor. On October 28, 2013, the FCC adopted an order on rural call completion imposing new reporting obligations and restricting certain call signaling practices. The call signaling rules went into effect on January 31, 2014. We filed for extensions of the rules, which the FCC granted, and as of April 17, 2014, we were compliant with the FCC call signaling rules. The effective date for the reporting requirements was April 1, 2015. We could be subject to an FCC enforcement action in the future in the event the FCC took the position that our rural call completion performance is inadequate or we were not compliant with the FCC’s order.
Federal - Numbering Rights
On April 18, 2013, the FCC issued a Notice of Proposed Rulemaking (NPRM) that proposed to modify FCC rules to allow VoIP providers to directlyissues, number slamming, 911 access, telephone numbers. In addition, the FCC granted a waiver from its existing rules to allow Vonage to conduct a trial of direct access to telephone numbers. The trial would allow the FCCtelecommunication equipment and services by persons with disabilities, caller ID services, number portability, unwanted calls to obtain real-world data on direct access to telephonereassigned numbers, by VoIP providers to inform consideration of the NPRM. Direct access to telephone numbers would facilitate IP to IP interconnection, which may allow VoIP providers to provide higher quality, lower cost services, promote the deployment of innovative new voice services, and experience reductions in the cost of telephony services. Vonage successfully completed the trial in certain markets and filed the required reports on the trial with the FCC. On January 31, 2014, the FCC Wireline Competition Bureau issued a positive report on the trial, concluding that Vonage's successful trial confirmed the technical feasibility of interconnected VoIP providers obtaining telephone numbers directly from the numbering administrators. On June 18, 2015, the FCC adopted an order that modifies its rules to allow interconnected VoIP providers to directly access telephone numbers. Part of the order required approval from the Office of Management and Budget ("OMB") prior to the rule change becoming effective. On February 4, 2016, the FCC announced that OMB had approved the order and would begin accepting applications for authorization beginning on February 18, 2016. Vonage applied for authorization, and on March 31, 2016 received authorization. On December 23, 2015, the National Association of Regulatory Utility Commissioners filed an appeal of the June 18, 2015 FCC order at the D.C. Circuit Court of Appeals. The D.C. Circuit held oral argument on this appeal on February 8, 2017.
Federal - Privacy Rules
On April 1, 2016, the FCC issued a Notice of Proposed Rulemaking (NPRM) that proposed the adoption of privacy rules for providers of broadband Internet access service and updating its rules for voice services to make them consistent with the proposed privacy rules for broadband Internet access services. In addition to regulating customer proprietary network information (CPNI), a category of information that the FCC has traditionally regulated for voice services, the FCC proposed to regulate use of customer personal information (PI), a broader set of information than CPNI, by broadband and voice service providers. Further, the NPRM would regulate voice and broadband provider privacy policies and data security practices, including imposing vicarious liability for vendors who handle PI and CPNI on behalf of a broadband or voice provider. Finally, the NPRM would impose another data breach reporting notification obligation on voice and broadband providers on top of existing state data breach notification requirements. The FCC adopted its new privacy rules at its October 27, 2016 open meeting. The rules do not provide for vicarious liability for vendors and provide an exemption from the rules in certain instances for business voice customers. Numerous parties have filed petitions for reconsideration.
State Telecommunications Regulation
In general, the focus of interconnected VoIP telecommunications regulation is at the federal level. On November 12, 2004, the FCC issued a declaratory ruling providing that our service is subject to federal regulation and preempted the Minnesota Public
Utilities Commission (“MPUC”) from imposing certain of its regulations on us. The FCC's decision was based on its conclusion that our service is interstate in nature and cannot be separated into interstate and intrastate components. On March 21, 2007, the United States Court of Appeals for the 8th Circuit affirmed the FCC's declaratory ruling preempting state regulation of our service.
While this ruling does not exempt us from all state oversight of our service, it effectively prevents state telecommunications regulators from imposing certain burdensome and inconsistent market entry requirements and certain other state utility rules and regulations on our service. State regulatorsrobocalling. As we continue to probeexpand globally, these types of regulations are likely to be similarly enacted and enforced by the limits of federal preemption in their attempts to apply state telecommunications regulation to interconnected VoIP service. On July 16, 2009, the Nebraska Public Service Commission and the Kansas Corporation Commission filed a petition with the FCC seeking a declaratory ruling or, alternatively, adoption of a rule declaring that state authorities may apply universal service funding requirements to nomadic VoIP providers. We participated in the FCC proceedings on the petition. On November 5, 2010, the FCC issued a declaratory ruling that allowed states to assess state USF on nomadic VoIP providers on a going forward basis provided that the states comply with certain conditions to ensure that imposing state USF does not conflict with federal law or policy. More recently on July 28, 2015, the MPUC found that it has authority to regulate Charter’s fixed, interconnected VoIP service. Charter challenged the MPUC’s order at the U.S. District Court for Minnesota. This challenge is currently pending. We expect that state public utility commissions and state legislators will continue their attempts to apply state telecommunications regulations to VoIP service.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 a reserve of $1,763$3,302 as of December 31, 20162018 as our best estimate of the potential tax exposure for any retroactive assessment. We believe the maximum estimated exposure for retroactive assessments is approximately $2,600 as of December 31, 2016.

He is also eligible for an annual performance bonus with a target based upon his then annual salary. The term of the employment contract with our Chief Executive Officer expires in 2017.

The table below summarizes the Merger Agreement.
Under the agreement, Nexmo shareholders are receiving consideration of $231,122, with an additional earn-out opportunity (the "Variable Payout Amount") of up to $20,000 contingent upon Nexmo achieving certain performance targets. Of the consideration, $194,684 (net of cashNewVoiceMedia assets acquired of $16,094) was paid at close, consisting of $163,093 of cash (net of $16,094 of cash acquired) and 6,823 in shares of Vonage common stock valued at $31,591. The remaining $36,438 of the $231,122 purchase price was in the form of restricted cash, restricted stock and options held by Nexmo management and employees (the "Employee Payout Amount"), subject to vesting requirements over time and to be amortized to compensation expense quarterly until vested. We financed the transaction with $179,000 from our 2016 Credit Facility. The purchase price is subject to adjustments pursuant to the merger agreement for closing cash and working capital of Nexmo, reductions for indebtedness and transaction expenses of Nexmo that remained unpaidliabilities assumed as of closing, and escrow fund deposits. The aggregate consideration will be allocated among Nexmo equityholders.
The consideration was allocated to acquisition cost as follows:October 31, 2018:

In addition, Nexmo shareholders were eligble to earn a Variable Payout AmountThe provisional fair values of up to $20,000, subject to the achievement of certain performance targets during the 12 month period following the closing of the transaction. The contingent consideration payable to the holders of Nexmo stock is determined based on (i) the achievement of certain revenue targets for the calendar year 2016, and (ii) Nexmo’s revenues received from its top customers following the closing. The contingent consideration may be in the form of cash, a number of shares of Vonage common stock or a combination thereof, at our sole discretion. We estimated using probability weighting that the value of the contingent consideration is $17,840intangible assets at the acquisition date were measured primarily based on significant inputs that are not observable in the market and included that amountthus represent a Level 3 measurement as defined in acquisition costASC 820. The fair values of the trade name, customer relationships and developed technology were determined utilizing variations of the income approach where the expected future cash flows resulting from the acquired identifiable intangible assets were reduced by operating costs and charges for contributory assets and then discounted to present value at the net present value amountweighted average cost of $16,472. As of September 30, 2016, we have adjusted our probability weighting based upon updated information and have reduced the value of the contingent consideration to $9,866 with a net present value of $9,110. This reduction in the contingent consideration of $7,362 was recorded in general and administrative expenses. As of December 31, 2016,
Nexmo did not achieve performance targets but the parties have agreed to a $5,000 settlement that the parties expect to be paid in the first quarter of 2017. As such we reduced the contingent consideration to $0 and recorded the reduction of the remaining net present value of $9,110 in general and administrative expenses. The $5,000 settlement has also been reflected in accrued expenses within the consolidated balance sheets and in general and administrative expenses in the consolidated statements of income.
In addition, Nexmo management and employees may earn an Employee Payout Amount of $36,438 attributable to restricted cash, restricted stock and assumed options, of which $4,779 is included in acquisition cost as service had been provided pre-acquisition and $31,659 will be recorded as post-acquisition expense assuming all amounts vest, of which $31,087 will be recorded as compensation expense and $572 will be recorded as interest expense as continued employment is a condition of receiving consideration.

Indications of fair value of the intangible assets acquired in connection with the acquisition were determined using either the income, market or replacement cost methodologies. The intangible assets are being amortized over periods which reflect the pattern in which economic benefits of the assets are expected to be realized. The customer relationships are being amortized on an accelerated basis over an estimated useful life of twelve years, the developed technologies are being amortized on an accelerated basis over an estimated useful life of eight years, the non-compete agreements are being amortized on a straight-line basis over three years, and trade names are being amortized on a straight-line basis over two years.
In addition, we recorded a deferred tax liability of $37,507 related to the $101,770 of identified intangible assets that will be amortized for financial reporting purposes but not for tax purposes and a deferred tax asset of $7,686 related to NOLs.
The excess of purchase price over the fair value amounts assigned to the assets acquired and liabilities assumed represents the amount of goodwill resulting from the acquisition. We do not expect any portion of this goodwill to be deductible for tax purposes. The goodwill attributable to the acquisition has been recorded as a non-current asset and is not amortized, but is subject to an annual review for impairment. We believe the factors that contributed to goodwill include synergies that are specific to our consolidated business, the acquisition of a talented workforce that provides us with expertise in the small and medium business market, as well as other intangible assets that do not qualify for separate recognition.
Acquisition of iCore
Pursuant to the Agreement and Plan of Merger dated August 19, 2015 by and among the Company, Cirrus Acquisition Corp., a Delaware corporation and newly formed indirect, wholly owned subsidiary of Vonage (“Merger Sub”), iCore, and Stephen G. Canton, as representative of the security holders of iCore, on August 31, 2015, Merger Sub, on the terms and subject to the conditions thereof, merged with and into iCore, and iCore became a wholly owned indirect subsidiary of Vonage.

iCore provides cloud-based unified communications and collaboration services, delivering voice, video, and mobile communications solutions to business customers. iCore is a natural complement to our rapid growing UCaaS business and strengthens our national footprint.
We acquired iCore for $92,689 in cash consideration, subject to adjustments pursuant to the merger agreement for closing cash and working capital of iCore, reductions for indebtedness and transaction expenses of iCore that remained unpaid as of closing, and escrow fund deposits. We financed the transaction with $10,689 of cash and $82,000 from our 2015 revolving credit facility. The aggregate consideration was allocated among iCore equity holders.
Pursuant to the merger agreement, $9,200 of the cash consideration was placed in escrow for unknown liabilities that may have existed as of the acquisition date.
During 2015, we incurred $1,353 in acquisition related transaction costs, which were recorded in general and administrative expense in the accompanying Consolidated Statements of Income.
The results of operations of the iCore business and the estimated fair values of the assets acquired and liabilities assumed have been included in our consolidated financial statements since the date of the acquisition.
The acquisition was accounted for using the acquisition method of accounting under which assets and liabilities of iCore were recorded at their respective fair values including an amount for goodwill representing the difference between the acquisition consideration and the fair value of the identifiable net assets. We do not expect any portion of this goodwill to be deductible for tax purposes. The goodwill attributable to the acquisition has been recorded as a non-current asset and is not amortized, but is subject to an annual review for impairment.

Sale of Hosted Infrastructure Product Line

On May 31, 2015:2017, we completed the sale of our Hosted Infrastructure product line for up to $4.0 million consideration comprised of $1.0 million received upon closing, an additional $0.5 million of contingent consideration received during the third quarter of 2017 and the potential for up to $2.5 million further consideration based on the achievement of financial objectives for net sales during the 18 months following closing. The results of our Hosted Infrastructure product line have historically been included within the Business segment. As a result of the sale, we recorded a gain $1,879 for the year ended December 31, 2017, within other income. This disposal did not represent a strategic shift in operations and, therefore, did not qualify for presentation as discontinued operations.

Acquisition of Telesphere
Pursuant to the Agreement and Plan of Merger (the “Telesphere Merger Agreement ”), dated November 4, 2014, by and among Vonage, Thunder Acquisition Corp., a Washington corporation and newly formed wholly owned subsidiary of Vonage (“Merger Sub”), Telesphere Networks Ltd. ("Telesphere"), and each of John Chapple and Gary O’Malley, as representative of the securityholders of Telesphere (collectively, the “Representative”). On December 15, 2014, Merger Sub merged with and into Telesphere, and Telesphere became a wholly owned subsidiary of Vonage (the “Merger”).
Telesphere offers a comprehensive range of cloud voice and UCaaS services, including advanced call center solutions, collaboration, mobile office, and HD multi-point video conferencing. Facilitating its cloud services delivery, Telesphere also provides integrated MPLS services over its nationwide network enabling quality of service (QoS) management and security increasingly required by businesses utilizing extensive UCaaS features.
We acquired Telesphere for $114,330, including 6,825 shares of Vonage common stock (which shares had an aggregate value of approximately $22,727 based upon the closing stock price on December 15, 2014) and cash consideration of $91,603 (of which $3,610 was paid in January 2015) including payment of $676 for excess cash as of closing date, a reduction for closing working capital of $105, reductions for indebtedness and transaction expenses of Telesphere that remained unpaid as of closing, and deposits into the escrow funds. We financed the transaction with $24,603 of cash and $67,000 from our 2014 revolving credit facility. The aggregate consideration will be allocated among Telesphere equity holders.
Pursuant to the Acquisition Agreement, $10,725 of the cash consideration and $2,875 of the stock consideration was placed in escrow (the "Holdback") for unknown liabilities that may have existed as of the acquisition date. $11,600 of the Holdback, which was included as part of the acquisition consideration, was paid to the former Telesphere shareholders within 18  months from the closing date of the Acquisition. $2,000 of the Holdback, which was included as part of the acquisition consideration, will be paid for such unknown tax specific liabilities or to the former Telesphere shareholders within 36 months from the closing date of the Acquisition.
During 2015 and 2014, we incurred $102 and $2,446, respectively, in acquisition related transaction costs, which were recorded in selling, general and administrative expense in the accompanying Consolidated Statements of Operations.
The results of operations of the Telesphere business and the estimated fair values of the assets acquired and liabilities assumed have been included in our consolidated financial statements since the date of the acquisition.
The acquisition was accounted for using the acquisition method of accounting under which assets and liabilities of Telesphere were recorded at their respective fair values including an amount for goodwill representing the difference between the acquisition consideration and the fair value of the identifiable net assets.
During the first quarter of 2015, the Company completed the process of allocating the acquisition price to identified intangible assets acquired as of the closing date, which had been in process as of December 31, 2014. The fair values assigned to tangible and identifiable intangible assets acquired and liabilities assumed are based on management’s estimates and assumptions.
The December 31, 2014 balance sheet has been revised to reflect the allocation of the purchase price for Telesphere based upon completion of our valuation analysis of intangible assets. The key revision was to record identified intangible assets of $50,925 with a corresponding reduction to goodwill.

The customer relationships and MPLS network are being amortized on an accelerated basis over an estimated useful life of seven years; developed technology is being amortized on an accelerated basis over an estimated useful life of ten years; and the non-compete agreements are being amortized on a straight-line basis over three years.
In addition, we recorded a deferred tax liability of $17,050 related to the $50,925 of identified intangible assets that will be amortized for financial reporting purposes but not for tax purposes and a deferred tax asset of $17,101 related to NOLs.

The excess of purchase price over the fair value amounts assigned to the assets acquired and liabilities assumed represents the amount of goodwill resulting from the acquisition. We do not expect any portion of this goodwill to be deductible for tax purposes. The goodwill attributable to the acquisition has been recorded as a non-current asset and is not amortized, but is subject to an annual review for impairment.

Note 12.14.    Noncontrolling Interest and Redeemable Noncontrolling InterestAccrued Liabilities

In the third quarter of 2013, we formed a consolidated foreign subsidiary in Brazil in connection with our previously announced joint venture in Brazil, which created a redeemable noncontrolling interest. The redeemable noncontrolling interest consists of the 30.0% interest in this subsidiary held by our joint venture partner.
In 2014, our joint venture partner did not make required capital calls and correspondingly its interest was diluted to 4% and was no longer contingently redeemable. As such, we reclassified the redeemable noncontrolling interest previously included in the mezzanine section of our Consolidated Balance Sheets to noncontrolling interest in the Stockholders' Equity section of our Consolidated Balance Sheets.

In December 2014 we announced plans to exit the Brazilian market for consumer telephony services and wind down our joint venture operations in the country. We completed the process at the end of the first quarter of 2015.
In connection with the wind down, we incurred approximately $111 and $1,972 in cash and non-cash charges, respectively, in the fourth quarter of 2014 related to severance-related expenses and asset write downs. We incurred approximately $500 in cash charges in 2015 related to contract terminations and severance-related expenses.

 
Note 13. Discontinued Operations
On March 31, 2015, the Company completed its previously announced exit from the Brazilian market for consumer telephony services and the associated wind down of its joint venture operations in the country. The Company incurred a loss on disposal of $824. The
loss on disposal is comprised of the write-off of noncontrolling interest of $907, foreign currency loss on intercompany loan forgiveness of $783, and residual cumulative translation of $192, partially offset by a tax benefit of $1,058.

Note 14.15. 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-makers reviewdecision-maker reviews revenue and gross margin information for each of our reportable segments, but dodoes 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.
Historically, we have had two operating segments that we have aggregated for reporting purposes. In 2016, as a result of the acquisition of Nexmo, we no longer meet the aggregation criteria for operating segments and now have the following two reportable segments:
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 (SIP)SIP based Voice over Internet Protocol, or VoIP network. Through Nexmo, the Vonage API Platform, we also offer Communications Platform as a Service, or 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 small and medium business, or 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.
