We believe the network needs for service providers, such as Telecom, following verticals: Cloud, Telecom/Cable, and Cloud Providers are converging, as are thoseStrategic Enterprise. In 2017, we began reporting revenue on these verticals, which we believe better aligns with our business model compared to our previous reporting of National Government, Financial Services,revenue by Service Provider and Strategic Enterprise Verticals, as allEnterprise. A summary of thesethe types of customers focus on high performance networks and build cloud environments.included in our verticals is discussed below.

Service Providers

Service providers generally include wireline and wireless carriers, and cable operators, as well as major Internet content and application providers, including those that provide social networking and search engine services. We support most of the major service provider networks in the world and our high-performance network infrastructure offerings are designed and built for the performance, reliability, and security that service providers demand. WeFurther, we believe our networking infrastructure offerings benefit our service providerkey customers by:

Reducing capital and operational costs by running multiple services over the same network using our secure, high density, highly automated, and highly reliable platforms;

Creating new or additional revenue opportunities by enabling new services to be offered to new market segments, which includes existing customers and new customers, based on our product capabilities;

Increasing customer satisfaction, while lowering costs, by enabling customers to self-select automatically provisioned service packages that provide the quality, speed, and pricing they desire; and

Providing increased asset longevity and higher return on investment as our customers' networks can scale to higher throughput based on the capabilities of our platforms.platforms;


While many of these service providers have historically been categorized separately as wireline, wireless, or cable operators, in recent years, we have seen increased convergence of these different types of service providers through acquisitions, mergers, and partnerships. Service providers are increasingly investing in the build-out of high performance networks and the transformation of existing central offices to distributed cloud environments.

We believe that there are several other industry trends affecting service providers for which we are well positioned to deliver products and solutions. These trends include: significant growth in Internet Protocol, or IP, traffic on service provider networks because of peer-to-peer interaction; broadband usage; video; an increasing reliance on the network as a mission critical business tool in the strategies of our service provider customers and of their enterprise customers; the advent of data center "clouds" to deliver business applications via IP network connected facilities; Network Functions Virtualization, or NFV, to allow more flexible deployment models; and growth in mobile traffic as a result of the increase in mobile device usage including smartphones, tablets, and connected devices of various kinds.

The infrastructure market for service providers includes: products and technology at the network core; the network edge to enable access; the aggregation layer; the data center where many services are created; security to protect from the inside out and the outside in; the application awareness and intelligence to optimize the network to meet business and user needs; and the management, service awareness, and control of the entire infrastructure.

Enterprise

Our high-performance network infrastructure offerings are designed to meet the performance, reliability, and security requirements of the world's most demanding enterprises. The enterprise market generally is comprised of financial services; national, federal, state, and local governments; research and educational institutions; and other business that view their networks as critical to their success.

Our Telecom/Cable vertical includes wireline and wireless carriers and cable operators, and we support most of the major carrier and operator networks in the world with our high-performance network infrastructure offerings. In recent years, we have seen increased convergence of these different types of customers through acquisitions, mergers, and partnerships. Telecom/Cable customers are increasingly investing in the build-out of high performance networks and the transformation of existing legacy infrastructure to distributed cloud environments in order to satisfy the growth in mobile traffic and video as a result of the increase in mobile device usage including smartphones, tablets, and connected devices of various kinds.

Further, as these customers prepare for next generation mobile network build-outs, or 5G, which we expect to begin to occur over the next few years, as well as create new approaches to delivering value to their enterprise customers, we believe these opportunities will present further opportunities for Juniper across our portfolio. The need for a highly efficient infrastructure to handle large amounts of data along with low latency, or minimal delay, plays into the need to have a high performance, scalable infrastructure in combination with the automation and flexibility required to drive down operational costs and rapidly provision applications. As our Telecom/Cable customers prepare for 5G, we expect that Network Function Virtualization, or NFV, and software-defined networking, or SDN, will be critical elements to enable our customers the flexibility to achieve the business use cases around Internet of Things, or IoT; enhanced mobile video support; and dynamic new service provider market, innovationdeployments. With our focus on delivering a strong portfolio of network virtualization and software-based orchestration solutions, we believe we will be poised to deliver on the automation and agility requirements needs of the Telecom/Cable vertical.

We also expanded our global alliances with NEC to deliver NFV-based solutions that allow service providers and enterprises to gain greater service agility through automation.

In addition,protect applications running in 2016 we completed three acquisitions that we expect will further enhance our product portfolio to accelerate our strategy in themultiple cloud transition. First, we acquired BTI Systems Inc., or BTI, to accelerate our ability to address the fast growing data center interconnect, or DCI, and metro Ethernet markets with a breadth of open, programmable and automated, packet optical transport solutions. Second, we acquired Aurrion, Inc., or Aurrion, which we expect will strengthen our long-term competitive advantage in cost-effective, high-density, high-speed optical networks. Lastly, we acquired AppFormix, Inc., which we expect will complement the analytics and capabilities of Contrail and help customers enhance their cloud operations. We will continue to look at targeted and strategic acquisitions that we believe can complement our product portfolio, operations or R&D strategy.environments.

Research and Development

We have assembled a team of skilled engineers with extensive experience in the fields of high-end computing, network system design, ASIC design, security, routing protocols, software applications and platforms, and embedded operating systems. As of December 31, 2016,2017, we employed 4,0543,723 people in our worldwide R&D organization.

We believe that strong product development capabilities are essential to our strategy of enhancing our core technology, developing additional applications, integrating that technology, and maintaining the competitiveness and innovation of our product and service offerings. In our products, we are leveraging our software, ASIC and systems technology, developing additional network interfaces targeted to our customers' applications, and continuing to develop technology to support the build-out of high performance networks and cloud environments. We continue to expand the functionality of our products to improve performance, reliability and scalability, and to provide an enhanced user interface.

Our R&D process is driven by our corporate strategy and the availability of new technology, market demand, and customer feedback. We have invested significant time and resources in creating a structured process for all product development projects. Following an assessment of market demand, our R&D team develops a full set of comprehensive functional product specifications based on inputs from the product management and sales organizations. This process is designed to provide a framework for defining and addressing the steps, tasks, and activities required to bring product concepts and development projects to market. Expenditures for R&D were $980.7 million, $1,013.7 million, and $994.5 million in 2017, 2016, and $1,006.2 million in 2016, 2015, and 2014, respectively.


Sales and Marketing

As of December 31, 2016,2017, we employed 2,5902,474 people in our worldwide sales and marketing organization. These sales and marketing employees operate in different locations around the world in support of our customers.

Our sales organization, with its structure of sales professionals, business development teams, systems engineers, marketing teams, channel teams, and an operational infrastructure team are generally distributed between vertical markets. Within each team, sales team members serve the following three geographic regions: (i) Americas (including United States, Canada, Mexico, Caribbean and Central and South America), (ii) EMEA, and (iii) APAC. Within each region, there are regional and country teams, as well as vertical market focused teams, to ensure we operate close to our customers.
Our sales teams operate in their respective regions and generally either engage customers directly or manage customer opportunities through our distribution and reseller relationships as described below.

We sell to a number of service providersCloud and Telecom/Cable customers directly. Otherwise, we sell to both service providers and enterprise customersall of our key customer verticals primarily through distributors and resellers.


Direct Sales Structure

The terms and conditions of direct purchasing arrangements are governed either by customer purchase orders and our order acknowledgment terms for those orders or by purchase contracts. The direct contracts with these customers set forth only general terms of sale and generally do not require customers to purchase specified quantities of our products. We directly receive and process customer purchase orders. 

Channel Sales Structure

A critical part of our sales and marketing efforts are our channel partners through which we conduct the majority of our sales. We utilize various channel partners, including but not limited to the following:

A global network of strategic distributor relationships, as well as region-specific or country-specific distributors who in turn sell to local VARs who sell to end-user customers. Our distribution channel partners resell routing, switching and security products and services, which are purchased by both enterprise and service provider customers.all of our key customer verticals. These distributors tend to be focusedfocus on particular regions or countries within regions. For example, we have substantial distribution relationships with Ingram Micro in the Americas and Hitachi in Japan. Our agreements with these distributors are generally non-exclusive, limited by region, and provide product and service discounts and other ordinary terms of sale. These agreements do not require our distributors to purchase specified quantities of our products or services. Further, most of our distributors sell our competitors' products and services, and some sell their own competing products and services.

VARs and Direct value-added resellers, including our strategic worldwide alliance partners referenced below, resell our products to end-users around the world. These channel partners either buy our products and services through distributors, or directly from us, and have expertise in designing, selling, and deploying complex networking solutions in their respective markets. Our agreements with these channel partners are generally non-exclusive, limited by region, and provide product and service discounts and other ordinary terms of sale. These agreements do not require these channel partners to purchase specified quantities of our products or services. Increasingly, our service providerCloud and Telecom/Cable customers also resell our products or services to their customers or purchase our products or services for the purpose of providing managed or cloud-based services to their customers.

Strategic worldwide reseller relationships with established Juniper alliances, comprised of Dimension Data Holdings, or Dimension Data; Ericsson Telecom A.B., or Ericsson; International Business Machines, or IBM; and NEC Corporation. These companies each offer services and products that complement our own product and service offerings and act as a reseller, and in some instances as an integration partner for our products. Our arrangements with these partners allow them to resell our products and services on a non-exclusive and generally global basis, provide for product and service discounts, and specify other general terms of sale. These agreements do not require these partners to purchase specified quantities of our products or services.


Manufacturing and Operations

As of December 31, 2016,2017, we employed 358326 people in worldwide manufacturing and operations who primarily manage relationships with our supply chain, which include our contract manufacturers, original design manufacturers, component suppliers, warehousing and logistics.

Our manufacturing is primarily conducted through contract manufacturers and original design manufacturers in the United States, or U.S.; China; Malaysia; Mexico;, China, Malaysia, Mexico, and Taiwan. As of December 31, 2016,2017, we utilized Celestica Incorporated, Flextronics International Ltd., Accton Technology Corporation, and Alpha Networks Inc. for the majority of our manufacturing activity. Our contract manufacturers and original design manufacturers in all locations are responsible for all phases of manufacturing from prototypes to full production and assist with activities such as material procurement, surface mount assembly, final assembly, test, control, shipment to our customers, and repairs. Together with our contract manufacturers and original design manufacturers, we design, specify, and monitor the tests that are required for our products to meet internal and external quality standards. TheseWe believe that these arrangements provide us with the following benefits:

We can quickly ramp up and deliver products to customers with turnkey manufacturing;

We gain economies of scale by leveraging our buying power with our contract manufacturers and original design manufacturers when we manufacture large quantities of products;

We operate with a minimum amount of dedicated space and employees for manufacturing operations; and

We can reduce our costs by reducing what would normally be fixed overhead expenses.

Our contract manufacturers and original design manufacturers build our products based on our rolling product demand forecasts. Each contract manufacturer procures components necessary to assemble the products in our forecast and tests the products according to agreed-upon specifications. Products are then shipped to our distributors, VARs, or end-users. Generally, we do not own the components. Title to the finished goods is generally transferred from the contract manufacturers to us when the products leave the contract manufacturer's location. Customers take title to the products upon delivery at a specified destination. If the product or components remain unused or the products remain unsold for a specified period, we may incur carrying charges or obsolete materials charges.

Our contracts with our contract manufacturers and original design manufacturers merely set forth a framework within which the contract manufacturer and original design manufacturer, as applicable, may accept purchase orders from us. These contracts do not represent long-term commitments.

We also purchase and hold inventory for strategic reasons and to mitigate the risk of shortages of certain critical component supplies. The majority of this inventory is production components. As a result, we may incur additional holding costs and obsolescence charges, particularly resulting from uncertainties in future product demand.

Some of our custom components, such as ASICs, are manufactured primarily by sole or limited sources, each of which is responsible for all aspects of production using our proprietary designs.

By working collaboratively with our suppliers, we endeavor to promote socially responsible business practices beyond our company and throughout our worldwide supply chain. To this end, we have adopted a supplierbusiness partner code of conduct and promote compliance with such code of conduct to our suppliers. One element of our supplierbusiness partner code of conduct is adoption and compliance with the Electronic IndustryResponsible Business Alliance Code of Conduct, or the EICC.Conduct. The EICC,Responsible Business Alliance, a coalition of electronics, retail, auto and toy companies, provides guidelines and resources to drive performance and compliance with critical corporate social responsibility policies. Its goal isgoals are to promote ethical business practices, eliminate human trafficking, and to ensure that working conditions in the electronic industry supply chain are safe, that workers are treated with respect and dignity, and that manufacturing processes are environmentally responsible. By using standard audit and assessment protocols and tools, we measure and monitor manufacturing partners’ and direct material suppliers’ compliance to the codes of conduct, including but not limited to: onsite audits; risk assessments; CDP climate change and water requests; and conflict minerals surveys. CDP is a global standardized mechanism by which companies can report their environmental performance on climate change, water and forest programs to institutional investors and customers. Our Corporate Citizenship and Sustainability Report and SupplierBusiness Partner Code of Conduct are available on our website.


Backlog

Our sales are made primarily pursuant to purchase orders under framework agreements either with our distributors, resellers or customers. At any given time, we have backlog orders for products that have not shipped. Because customers may cancel purchase orders or change delivery schedules without significant penalty, we believe that our backlog at any given date may not be a reliable indicator of future operating results. As of December 31, 20162017 and December 31, 2015,2016, our total product backlog was approximately $441.2$400.7 million and $517.4$441.2 million, respectively. Our product backlog consists of confirmed orders for products scheduled to be shipped to customers, generally within the next six months, and excludes orders from distributors as we recognize product revenue on sales made through distributors upon sell-through to end-users. Backlog also excludes certain future revenue adjustments for items such as product revenue deferrals, sales return reserves, service revenue allocations, and early payment discounts.

Seasonality

We, as do many companies in our industry, experience seasonal fluctuations in customer spending patterns. Historically, we have experienced stronger customer demand in the fourth quarter and weaker demand in the first quarter. This historical pattern should not be considered a reliable indicator of our future net revenues or financial performance.

Competition

We compete in the network infrastructure markets. These markets are characterized by rapid change, converging technologies, and a migration to networking solutions that offer agility advantages. In the network infrastructure business, Cisco Systems, Inc., or Cisco, has historically been the dominant player. However, our principal competitors also include Arista Networks, Inc., or Arista; Brocade Communications Systems, Inc., or Brocade, which is expected to be acquired by Broadcom Limited in 2017; Dell Inc., or Dell; Hewlett Packard Enterprise Co., or HPE; Huawei Technologies Co., Ltd., or Huawei; and Nokia Corporation, or Nokia.

Many of our current and potential competitors, such as Cisco, Nokia, HPE, and Huawei, among others, have broader portfolios which enable them to bundle their networking products with other networking and information technology products in a manner that may discourage customers from purchasing our products. Many of our current and potential competitors have greater name recognition, marketing budgets, and more extensive customer bases that they may leverage to compete more effectively. Increased competition could result in price reductions, fewer customer orders, reduced gross margins, and loss of market share, negatively affecting our operating results.

In addition, there are a number of other competitors in the security network infrastructure space, including Palo Alto Networks, Inc., or Palo Alto Networks; Check Point Software Technologies, Ltd., or Check Point; F5 Networks, Inc., or F5 Networks; and Fortinet, Inc., or Fortinet; among others, who tend to be focused specifically on security solutions and, therefore, may be considered specialized compared to our broader product line.

We expect that over time, large companies with significant resources, technical expertise, market experience, customer relationships, and broad product lines, such as Cisco, Nokia, and Huawei, will introduce new products designed to compete more effectively in the market. There are also several other companies that aim to build products with greater capabilities to compete with our products. Further, there has been significant consolidation in the networking industry, with smaller companies being acquired by larger, established suppliers of network infrastructure products. We believe this trend is likely to continue which may increase the competitive pressure faced by us due to their increased size and breadth of their product portfolios.

In addition to established competitors, a number of public and private companies have announced plans for new products to address the same needs that our products address. We believe that our ability to compete depends upon our ability to demonstrate that our products are superior and cost effective in meeting the needs of our current and potential customers.

As a result, we expect to face increased competition in the future from larger companies with significantly more resources than we have and also from emerging companies that are developing new technologies. Although we believe that our technology and the purpose-built features of our products make them unique and will enable us to compete effectively with these companies, we cannot guarantee that we will be successful.


Environment

We are committed to maintaining compliance with all environmental laws applicable to our operations, products and services and to reducing our environmental impact across our business and supply chain. Our operations and many of our products are subject to various federal, state, local and foreign regulations that have been adopted with respect to the environment, such as the Waste

Electrical and Electronic Equipment, or WEEE, Directive; Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment, or RoHS; and Registration, Evaluation, Authorization, and Restriction of Chemicals, or REACH, regulations adopted by the European Union and China. To date, compliance with federal, state, local, and foreign laws enacted for the protection of the environment has had no material effect on our capital expenditures, earnings, or competitive position. However, see the risk factor entitled "Regulation of our industry in general and the telecommunications industry in particular could harm our operating results and future prospects" in the section entitled Risk Factors in Item 1A of Part I of this Report for additional information concerning regulatory compliance.

Juniper’s greatest impact on the environment is through our products and services. Juniper has an environmental program, based on our new product introduction process, that focuses on energy efficiency, materials innovation, and recyclability. We consider opportunities to minimize resource impacts and improve efficiencies over a product’s life cycle, from the materials we use and a product’s energy footprint, to packaging and end-of-life, or EOL, activities such as reuse, refurbishment, and recycling.

We are committed to the environment through our efforts to improve the energy efficiency per gigabit of throughput of key elements in our high-performance network product offerings. With the launch of the PTX series, we pioneered, among other ground-breaking achievements, recordOur products are independently tested by third parties for energy efficiency of 1.5W per Gigabit of throughput. Since then, we have continued to enhance the PTX series, delivering market-leading energy efficiency of 1.2W per Gigabit of throughput in 2014 and further improving energy efficiency of 0.4W per Gigabit with the 3Tbps FPC3 line-card in 2015. In addition,compliance. As an example, our MX series 3D Universal Edge Routers are deliveringoffer breakthrough energy efficiency ofwith the MX10003 delivering ultra-high density in a space- and power-optimized package, while consuming 0.8W per Gigabit at the network edge, breaking the 1W per Gigabit barrier. The environment will remain a focus area across multiple aspects of our business.throughput. Additionally, we have redesigned packaging in ways that optimizes costs while minimizing resource impacts.

We are also voluntarily participating in the Carbon Disclosure Project, or CDP climate change and water disclosures and encourage our direct material suppliers representing an aggregate of at least 80% of our consolidated total direct expenditure and 100% of our manufacturing partners to do the same. CDP is a global standardized mechanism by which companies report their greenhouse gas emissions to institutional investors and customers. Additionally, Juniper iswe are a member of the EICCResponsible Business Alliance, or RBA, and hashave adopted and promotespromote the adoption by our suppliers of the practices of the EICCRBA Code of Conduct, as discussed above.above in the section entitled Manufacturing and Operations. We continue to invest in the infrastructure and systems required to execute on, monitor and drive environmental improvements in our global operations and within our supply chain.

Intellectual Property

Our success and ability to compete are substantially dependent upon our internally developed technology and expertise, as well as our ability to obtain and protect necessary intellectual property rights. While we rely on patent, copyright, trade secret, and trademark law, as well as confidentiality agreements, to protect our technology, we also believe that factors such as the technological and creative skills of our personnel, new product developments, frequent product enhancements, and reliable product maintenance are essential to establishing and maintaining a technology leadership position. There can be no assurance that others will not develop technologies that are similar or superior to our technology.

In addition, we integrate licensed third-party technology into certain of our products and, from time to time, we need to renegotiate these licenses or license additional technology from third parties to develop new products or product enhancements or to facilitate new business models. There can be no assurance that third-party licenses will be available or continue to be available to us on commercially reasonable terms or at all. Our inability to maintain or re-license any third-party licenses required in our products or our inability to obtain third-party licenses necessary to develop new products and product enhancements could require us to obtain substitute technology of lower quality or performance standards or at a greater cost, any of which could harm our business, financial condition, and results of operations.

As of December 31, 2016,2017, we had over 2,9003,300 patents worldwide and numerous patent applications are pending. Patents generally have a term of twenty years from filing. As our patent portfolio has been built over time, the remaining terms on the individual patents vary. We cannot be certain that patents will be issued on the patent applications that we have filed, that we will be able to obtain the necessary intellectual property rights, or that other parties will not contest our intellectual property rights.


Employees

As of December 31, 2016,2017, we had 9,8329,381 full-time employees. We have not experienced any work stoppages, and we consider our relations with our employees to be good. Competition for qualified personnel in our industry is intense. We believe that our future success depends in part on our continued ability to hire, motivate, and retain qualified personnel. We believe that we have been successful in recruiting qualified employees, but there is no assurance that we will continue to be successful in the future.

Our future performance depends significantly upon the continued service of our key technical, sales, and senior management personnel, none of whom are bound by an employment agreement requiring service for any defined period of time. The loss of one or more of our key employees could have a material adverse effect on our business, financial condition, and results of operations.

Item 1A. Risk Factors

Factors That May Affect Future Results

Investments in our securities involve significant risks. Even small changes in investor expectations for our future growth and earnings, whether as a result of actual or rumored financial or operating results, changes in the mix of the products and services sold, acquisitions, industry changes, or other factors, could trigger, and have triggered in the past, significant fluctuations in the market price of our common stock. Investors in our securities should carefully consider all of the relevant factors disclosed by us, including, but not limited to, the following factors, that could affect our business, operating results and stock price.

Our quarterly results are unpredictable and subject to substantial fluctuations; as a result, we may fail to meet the expectations of securities analysts and investors, which could adversely affect the trading price of our common stock.

Our revenues and operating results may vary significantly from quarter-to-quarter due to a number of factors, many of which are outside of our control and any of which may cause our stock price to fluctuate.

The factors that may cause our quarterly results to vary quarter by quarter and be unpredictable include, but are not limited to:

limited visibility into customer spending plans, plans;
changes in customer mix, mix;
changes in the mix of products and services sold, sold;
changes in the mix of geographies in which our products and services are sold, sold;
changing market and economic conditions, conditions;
current and potential customer, partner and supplier consolidation and concentration, competition, concentration;
price and product competition;
long sales, qualification and implementation cycles, cycles;
unpredictable ordering patterns and reduced visibility into our customers’ spending plans and associated revenue;
how well we execute on our strategy and operating plans and the impact of changes in our business model that could result in significant restructuring charges;
our ability to achieve targeted cost reductions;
changes in tax laws or accounting rules, or interpretations thereof;
changes in the amount and frequency of share repurchases or dividends, dividends;
regional economic and political conditions,conditions; and
seasonality.

For example, we, and many companies in our industry, experience adverse seasonal fluctuations in customer spending, particularly in the first quarter. In addition, while we may have backlog orders for products that have not shipped, we believe that our backlog may not be a reliable indicator of future operating results for a number of reasons, including project delays, changes in project scope and the fact that our customers may cancel purchase orders or change delivery schedules without significant penalty. Furthermore, market trends, competitive pressures, commoditization of products, seasonal rebates and discounting, increased component or shippinglogistics costs, issues with product quality, regulatory impacts and other factors may result in reductions in revenue or pressure on gross margins in a given period, which may necessitate adjustments to our operations. Such adjustments may be difficult or impossible to execute in the short or medium term.

As a result of these factors, as well as other variables affecting our operating results, we believe that quarter-to-quarter comparisons of operating results are not necessarily a good indication of what our future performance will be. It is likely that in some quarters,In the past, our operating results will behave been below our guidance, our long-term financial model or the expectations of securities analysts or investors, and this may happen in the future, in which case the price of our common stock may decline and has declined in the past. Such a decline could also occur, and has occurred in the past, even when we have met our publicly stated revenues and/or earnings guidance.


We expect our gross margins and operating margins to vary over time, and the level of gross margins and operating margins we have achieved in recent years may not be sustainable.

We expect our product and service gross margins to vary, both in the near-term and in the long-term, and the gross margins we have achieved in recent years may not be sustainable and may be adversely affected in the future by numerous factors, some of which have occurred and may occur in the future, including customer, vertical, product and geographic mix shifts, an increase or decrease in our software sales or services we provide, increased price competition in one or more of the markets in which we compete, changes in the actions of our competitors or their pricing strategies, which may be difficult to predict and respond to, modifications to our pricing strategy in order to gain footprint in certain markets or with certain customers, currency fluctuations that impact our costs or the cost of our products and services to our customers, increases in material, labor, logistics, warranty costs, or inventory carrying costs, excess product component or obsolescence charges from our contract manufacturers, issues with manufacturing or component quality or efficiencies, increased costs due to changes in component pricing or charges incurred due to inaccurately forecasting product demand, warranty related issues, or our introduction of new products and enhancements or entry into new markets with different pricing and cost structures. For example, in fiscal year 2017, our margins decreased as compared to fiscal year 2016, primarily due to lower product net revenues and product mix, resulting from the year-over-year decline in routing revenues, our customers' architectural shifts, and higher costs of certain memory components. In fiscal year 2016, our margins decreased compared to fiscal year 2015, primarily due to elevated pricing pressure and product mix. In fiscal year 2015, our margins increased compared to fiscal year 2014, as a result of higher restructuring and other charges recorded in 2014 but not in 2015, in connection with the restructuring plan we initiated in the first quarter of 2014. Failure to sustain or improve our gross margins reduces our profitability and may have a material adverse effect on our business and stock price.

Further, we will continue to remain diligent in our long-term financial objective to increase revenue and operating margins and manage our operating expenses as a percentage of revenue. We expect that our margins will vary with our ability to achieve these goals. We can provide no assurance that we will be able to achieve all or any of the goals of these plans or meet our announced expectations, in whole or in part, or that our plans will have the intended effect of improving our margins on the expected timeline, or at all.

A limited number of our customers comprise a material portion of our revenues and any changes in the way they purchase products and services from us could affect our business. In addition, there is an ongoing trend toward consolidation in the industry in which our customers and partners operate. Any decrease in revenues from our customers or partners could have an adverse effect on our net revenues and operating results.

A material portion of our net revenues depend on sales to a limited number of customers and distribution partners, particularly in our Telecom/Cable and Cloud verticals. Changes in the business requirements or focus, vendor selection, project prioritization, financial prospects, capital resources, and expenditures, or purchasing behavior (including product mix purchased or delays in deployment) of our key customers could significantly decrease our sales to such customers or could lead to delays or cancellations of planned purchases of our products or services, which increases the risk of quarterly fluctuations in our revenues and operating results. Any of these factors could adversely affect our business, financial condition, and results of operations.

In addition, in recent years, there has been movement towards consolidation in the telecommunications industry (for example, CenturyLink, Inc.'s acquisition of Level 3 Communications, Inc., and Vodafone India’s proposed acquisition of Idea Cellular Ltd.) and that consolidation trend has continued. Certain telecommunications companies have also announced their intent towards vertical consolidation through acquisitions of media and content companies, such as Verizon’s acquisition of Yahoo and AT&T’s proposed acquisition of Time Warner. If our customers or partners are parties to consolidation transactions they may delay, suspend or indefinitely reduce or cancel their purchases of our products or other direct or indirect unforeseen consequences could harm our business, financial condition, and results of operations.


We sell our products to customers that use those products to build networks and IP infrastructure, and if the demand for network and IP systems does not continue to grow, our business, financial condition, and results of operations could be adversely affected.

A substantial portion of our business and revenues depends on the growth of secure IP infrastructure and on the deployment of our products by customers that depend on the continued growth of IP services. As a result of changes in the economy, capital spending or the building of network capacity in excess of demand, all of which have in the past particularly affected telecommunications service providers, spending on IP infrastructure can vary, which could have a material adverse effect on our business, financial condition, and results of operations. In addition, a number of our existing customers are evaluating the build-out of their next generation networks. During the decision-making period when our customers are determining the design of those networks and the selection of the software and equipment they will use in those networks, such customers may greatly reduce or suspend their spending on secure IP infrastructure. For example, in the second half of 2017, our switching and routing results were adversely affected by spending delays from our largest cloud customers, who we believe are in the process of implementing a networking architectural shift. The duration of the delay is difficult to predict, in part because each cloud customer will migrate their network architecture based on their own constraints. Such delays in purchases can make it more difficult to predict revenues from customers, can cause fluctuations in the level of spending by customers and, even where our products are ultimately selected, can have a material adverse effect on our business, financial condition, and results of operations.

Fluctuating economic conditions make it difficult to predict revenues and gross margin for a particular period and a shortfall in revenues or increase in costs of production may harm our operating results.

Our revenues and gross margin depend significantly on general economic conditions and the demand for products in the markets in which we compete. Economic weakness or uncertainty, customer financial difficulties, and constrained spending on network expansion and enterprise infrastructure have in the past resulted in, and may in the future result in, decreased revenues and earnings. Such factors could make it difficult to accurately forecast salesrevenues and operating results and could negatively affect our ability to provide accurate forecasts to our contract manufacturers and manage our contract manufacturer relationships and other expenses. In addition, economic instability or uncertainty, as well as continued turmoil in the geopolitical environment in many parts of the world, have, and may continue to, put pressure on economic conditions, which has led and could lead, to reduced demand for our products, to delays or reductions in network expansions or infrastructure projects, and/or higher costs of production. More generally-speaking, economic weakness may also lead to longer collection cycles for payments due from our customers, an increase in customer bad debt, restructuring initiatives and associated expenses, and impairment of investments. Furthermore, instability in the global markets may adversely impact the ability of our customers to adequately fund their expected capital expenditures, which could lead to delays or cancellations of planned purchases of our products or services. Our operating expenses are largely based on anticipated revenue trends and a high percentage of our expenses is, and will continue to be, fixed in the short and medium term. Therefore, fluctuations in revenue and gross margins could cause significant variations in our operating results and operating margins from quarter to quarter. Uncertainty about future economic conditions also makes it difficult to forecast operating results and to make decisions about future investments. Future or continued economic weakness, failure of our customers and markets to recover from such weakness, customer financial difficulties, increases in costs of production, and reductions in spending on network maintenance and expansion could result in price concessions in certain markets or have a material adverse effect on demand for our products and consequently on our business, financial condition, and results of operations.


Our success depends upon our ability to effectively plan and manage our resources and restructure our business through rapidly fluctuating economic and market conditions, and such actions may have an adverse effect on our financial and operating results.

Our ability to successfully offer our products and services in a rapidly evolving market requires an effective planning, forecasting, and management process to enable us to effectively scale and adjust our business and business models in response to fluctuating market opportunities and conditions.

From time to time, we have increased investment in our business by, for example, increasing headcount, acquiring companies, and increasing our investment in R&D, sales and marketing, and other parts of our business. Conversely, in 2014,February 2017 we initiated the 2017 Restructuring Plan to refocus the Company’s strategy, optimize its structure and improve operational efficiencies, we implemented a new strategic focus, realigned our organization into a One-Juniper structure, reducedrealign our workforce consolidated and closed facilities, made changes to enhance efficiency, improved cost management measuresincrease operational efficiencies. This included workforce reductions and instituted a new capital allocation plan. In connection withcontract terminations. As we assessed the performance of our cost management measures, we implemented a substantial cost reduction plan accomplished through variousoperating results against our long-term operating goals and evaluated potential opportunities for improvement, the 2017 Restructuring Plan was expanded and additional restructuring activities across research and development, sales and marketing, and general and administrative. We recorded a goodwill impairment charge of $850.0 millioncharges were incurred in the fourth quarter of 2014 due2017 to the underperformance offurther align our Security reporting unit and product rationalizations. Further strategy-related pivots could lead to delays in achieving revenue and profit forecasts and result in additional impairment.workforce. Some of our expenses are fixed costs that cannot be rapidly or easily adjusted in response to fluctuations in our business or numbers of employees. Rapid changes in the size, alignment or organization of our workforce, including sales account coverage, could adversely affect our ability to develop and deliver products and services as planned or impair our ability to realize our current or future business and financial objectives. Our ability to achieve the anticipated cost savings and other benefits from our restructuring initiatives within the

expected time frame is subject to many estimates and assumptions. These estimates and assumptions are subject to significant economic, competitive and other uncertainties, some of which are beyond our control. If these estimates and assumptions are incorrect, if we are unsuccessful at implementing changes, or if other unforeseen events occur, our business and results of operations could be adversely affected.

We expect our gross margins and operating margins to vary over time, and the level of gross margins achieved by us in recent years may not be sustainable.

We expect our product and service gross margins to vary, both in the near-term and in the long-term, and the gross margins we have achieved in recent years may not be sustainable and may be adversely affected in the future by numerous factors, some of which have occurred and may occur in the future, including customer, product and geographic mix shifts, an increase or decrease in our software sales or services we provide, increased price competition in one or more of the markets in which we compete, changes in the actions of our competitors or their pricing strategies, which may be difficult to predict and respond to, currency fluctuations that impact our costs or the cost of our products and services to our customers, increases in material, labor, or inventory carrying costs, excess product component or obsolescence charges from our contract manufacturers, issues with manufacturing or component quality or efficiencies, increased costs due to changes in component pricing or charges incurred due to component holding periods if we do not accurately forecast product demand, warranty related issues, or our introduction of new products and enhancements or entry into new markets with different pricing and cost structures. For example, in fiscal year 2016, our margins decreased compared to fiscal year 2015, primarily due to elevated pricing pressure and product mix. In fiscal year 2015, our margins increased compared to fiscal year 2014, as a result of higher restructuring and other charges recorded in 2014 but not in 2015, in connection with the restructuring plan we initiated in the first quarter of 2014. In fiscal year 2014, our margins declined compared to fiscal year 2013, as a result of higher inventory charges resulting from product rationalizations in connection with our 2014 restructuring plan and an industry-wide memory product quality defect for a component from a third party. We determine our operating expenses largely on the basis of anticipated revenues and a high percentage of our expenses are fixed in the short and medium term. As a result, a failure or delay in generating or recognizing revenue could cause significant variations in our operating results and operating margin from quarter-to-quarter. Failure to sustain or improve our gross margins reduces our profitability and may have a material adverse effect on our business and stock price.

Further, we will continue to remain diligent in our long-term financial objective to increase revenue and operating margins and manage our operating expenses as a percentage of revenue. We expect that our margins will vary with our ability to achieve these goals. We can provide no assurance that we will be able to achieve all or any of the goals of these plans or meet our announced expectations, in whole or in part, or that our plans will have the intended effect of improving our margins on the expected timeline, or at all.


A limited number of our customers comprise a material portion of our revenues and any changes in the way they purchase products and services from us could affect our business. In addition, there is an ongoing trend toward consolidation in the industry in which our customers and partners operate. Any decrease in revenues from our customers or partners could have an adverse effect on our net revenues and operating results.

A material portion of our net revenues depend on sales to a limited number of customers and distribution partners, particularly in our service provider market. Changes in the business requirements or focus, vendor selection, project prioritization, financial prospects, capital resources, and expenditures, or purchasing behavior (including product mix purchased) of our key customers could significantly decrease our sales to such customers or could lead to delays or cancellations of planned purchases of our products or services, which increases the risk of quarterly fluctuations in our revenues and operating results. Any of these factors could adversely affect our business, financial condition, and results of operations.

In addition, in recent years, there has been movement towards consolidation in the telecommunications industry (for example, Altice’s purchase of Cablevision and Portugal Telecom, Liberty Global's acquisition of Cable & Wireless Communications, Charter Communications, Inc.'s acquisition of Time Warner Cable, Inc., and CenturyLink's proposed acquisition of Level 3 Communications) and that consolidation trend has continued. Certain telecommunications companies have also announced their intent towards vertical consolidation through acquisitions of media and content companies, such as Verizon’s proposed acquisition of Yahoo and AT&T’s proposed acquisition of Time Warner. If our customers or partners are parties to consolidation transactions they may delay, suspend or indefinitely reduce or cancel their purchases of our products or other direct or indirect unforeseen consequences could harm our business, financial condition, and results of operations.

We face intense competition that could reduce our revenues and adversely affect our business and financial results.

Competition is intense in the markets that we serve. The network equipment market hasrouting and switching markets have historically been dominated by Cisco, with competition coming from other companies such as Nokia Corporation (following its acquisition of Alcatel-Lucent), Arista, Brocade, HPE, and Huawei. In the security market, we face intense competition from Cisco and Palo Alto Networks, as well as companies such as Check Point, F5 Networks, Fortinet, and HPE.Fortinet. Further, a number of other small public and private companies have products or have announced plans for new products to address the same challenges and markets that our products address.

In addition, actual or speculated consolidation among competitors, or the acquisition by, or of, our partners and/or resellers by competitors can increase the competitive pressures faced by us as customers may delay spending decisions or not purchase our products at all. For example, in recent years, Nokia Corporation merged with Alcatel-Lucent, HPE acquired Aruba Networks, Cisco acquired OpenDNS,AppDynamics, Symantec Corporation acquired Blue Coat Systems, and Dell acquired EMC, which further consolidated our market. A number of our competitors have substantially greater resources and can offer a wider range of products and services for the overall network equipment market than we do. In addition, some of our competitors have become more integrated, including through consolidation, and offer a broader range of products and services, which could make their solutions more attractive to our customers. Many of our competitors sell networking products as bundled solutions with other IT products, such as computer and storage systems. If we are unable to compete successfully against existing and future competitors on the basis of product offerings or price, we could experience a loss in market share and revenues and/or be required to reduce prices, which could reduce our gross margins, and which could materially and adversely affect our business, financial condition, and results of operations. Our partners and resellers generally sell or resell competing products on a non-exclusive basis and consolidation could delay spending or require us to increase discounts to compete, which could also adversely affect our business.

The long sales and implementation cycles for our products, as well as our expectation that some customers will sporadically place large orders with short lead times, may cause our revenues and operating results to vary significantly from quarter-to-quarter.

A customer's decision to purchase certain of our products, particularly new products, involves a significant commitment of its resources and a lengthy evaluation and product qualification process. As a result, the sales cycle may be lengthy. In particular, customers making critical decisions regarding the design and implementation of large network deployments may engage in very lengthy procurement processes that may delay or impact expected future orders. Throughout the sales cycle, we may spend considerable time educating and providing information to prospective customers regarding the use and benefits of our products. Even after making the decision to purchase, customers may deploy our products slowly and deliberately. Timing of deployment can vary widely and depends on the skill set of the customer, the size of the network deployment, the complexity of the customer's network environment, and the degree of hardware and operating system configuration necessary to deploy the products. Customers with large networks usually expand their networks in large increments on a periodic basis. Accordingly, we may receive purchase orders for significant dollar amounts on an irregular basis. These long cycles, as well as our expectation that customers will tend to sporadically place large orders with short lead times, both of which may be exacerbated by the impact of continued global economic weakness, may cause revenues and operating results to vary significantly and unexpectedly from quarter-to-quarter.

The timing of product orders and/or our reliance on revenue from sales of software or subscriptionsubscriptions and professional, support and maintenance services may cause us to recognize revenue in a different period than the one in which a transaction takes place. This may make it difficult for investors to observe quarterly trends and may cause significant variations in our operating results and operating margin on a quarterly basis.

Generally, our network equipment products are stocked only in limited quantities by our distributors and resellers due to the cost, complexity and custom nature of configurations required by our customers; we generally build such products as orders are received. The volume of orders received late in any given fiscal quarter remains unpredictable. If orders for certain products are received late in any quarter, we may not be able to recognize revenue for these orders in the same period, which could adversely affect our ability to meet our expected revenues for such quarter.

In addition, services revenue accounts for a significant portion of our revenue, comprising 29%31%, 27%29%, and 26%27% of total revenue in fiscal year 2017, 2016, 2015, and 2014,2015, respectively. Sales of new or renewal professional services, support and maintenance contracts may decline and/or fluctuate as a result of a number of factors, including end-customers’ level of satisfaction with our products and services, the prices of our products and services the prices of products and servicesor those offered by our competitors, and reductions in our end-customers’

spending levels. We recognize professional services, support and maintenance revenue periodically over the term of the relevant service period.

The introduction of new software products and services is part of our intended strategy to expand our software business, and certain software revenues may be recognized periodically over the term of the relevant use period or subscription period. As a result, much of thecertain software, subscription and support and maintenance revenue we report each fiscal quarter is the recognition of deferred revenue from software, subscription and support and maintenance contracts entered into during previous fiscal quarters. Consequently, a decline in such new or renewed contracts in any one fiscal quarter will not be fully or immediately reflected in revenue in that fiscal quarter but will negatively affect our revenue in future fiscal quarters. Accordingly, the effect of significant downturns in new or renewed sales of our software, subscriptions or support and maintenance is not reflected in full in our operating results until future periods. Also, it is difficult for us to rapidly increase oursuch software or services revenue through additional software or services sales in any period, as revenue from new and renewalthose software, subscription and support and maintenance contracts must be recognized over the applicable service period.

Additionally, we determine our operating expenses largely on the basis of anticipated revenues and technology roadmap and a high percentage of our expenses are fixed in the short and medium term. As a result, a failure or delay in generating or recognizing revenue could cause significant variations in our operating results and operating margin from quarter-to-quarter.

If we do not successfully anticipate technological shifts, market needs and opportunities, and develop products, product enhancements and business strategies that meet those technological shifts, needs and opportunities, or if those products are not made available or strategies are not executed in a timely manner or do not gain market acceptance, we may not be able to compete effectively and our ability to generate revenues will suffer.

The markets for our products are characterized by rapid technological change, frequent new product introductions, changes in customer requirements, continued pricecontinuous pricing pressures and a constantly evolving industry. We cannot guarantee that we willmay not be able to anticipate future technological shifts, market needs and opportunities or be able to develop new products, product enhancements or business strategies to meet such technological shifts, needs or opportunities in a timely manner or at all. For example, the move from traditional wide area network, or WAN, infrastructures towards software-defined networking,WAN, or SDN,SD-WAN, has been receiving considerable attention. In our view, it will take several years to see the full impact of SDN,SD-WAN, and we believe the successful products and solutions in this market will combine hardware and software elements. If we fail to anticipate market requirements or opportunities or fail to develop and introduce new products, product enhancements or business strategies to meet those requirements or opportunities in a timely manner, it could cause us to lose customers, and such failure could substantially decrease or delay market acceptance and sales of our present and future products and services, which would significantly harm our business, financial condition, and results of operations. In addition, if we invest time, energy and resources in developing products for a market that doesn't develop, it could likewise significantly harm our business, financial condition, and results of operations. Even if we are able to anticipate, develop, and commercially introduce new products, enhancements or business strategies, there can be no assurance that new products, enhancements or business strategies will achieve widespread market acceptance.

In the past tworecent years, we have announced a number of new products and enhancements to our hardware and software products across routing, switching and security, including ACX5000 and ACX500 routers, QFX10000 line of spine switches, QFX5100, QFX5200, QFX5100-AA, QFX-PFA, SRX300, SRX1500, SRX5000 with Express Path and SRX5800 Series Services Gateways, EX9200, EX4600, EX2300 and EX3400 Ethernet Switches, new MX Series line-cards and routers (including the vMX 3D Universal Edge Router), new PTX Series line cards (powered by our ExpressPlus custom silicon), Junos Fusion Provider Edge, Junos Fusion Data Center, Junos Fusion Enterprise, a disaggregated version of Junos Software, PTX1000, vSRX virtual firewall, Sky Advanced

Threat Prevention (ATP), Junos Space Security Director, Junos Space Virtual Director, Juniper Networks Contrail Networking, Contrail Service Orchestration, the NFX250 network services platform, cSRX compact and containerized firewall, enhancements to Junos Space Security Director and Sky ATP, SRX4100 and SRX4200 firewalls, and Junos Space Security Director Policy Enforcer .security. The success of our new products depends on several factors, including, but not limited to, component costs, timely completion and introduction of these products, prompt resolution of any defects or bugs in these products, our ability to support these products, differentiation of new products from those of our competitors and market acceptance of these products.

The introduction of new software products is part of our intended strategy to expand our software business. We have also begun to disaggregate certain software from certain hardware products, such that customers would be able to purchase or license our hardware and software products independently, which we expect could in time enable our hardware to be deployed with third party networking applications and services and our software to be used with third party hardware. For example, we have developed a disaggregated version of our Junos software and introduced our QFX5200 series of switches, which runs our disaggregated Junos software. The success of our strategy to expand our software business, including our strategy to disaggregate software from certain hardware products, is subject to a number of risks and uncertainties, including:

the additional development efforts and costs required to create new software products and/or to make our disaggregated products compatible with multiple technologies;

the possibility that our new software products or disaggregated products may not achieve widespread customer adoption;

the potential that our strategy could erode our revenue and gross margins;

the impact on our financial results of longer periods of revenue recognition and changes in tax treatment associated with software sales;


the additional costs associated with regulatory compliance and changes we need to make to our distribution chain in connection with increased software sales;

the ability of our disaggregated hardware and software products to operate independently and/or to integrate with current and future third party products; and

the risk that issues with third party technologies used with our disaggregated products willmay be attributed to us.

If any of our new products or business strategies do not gain market acceptance or meet our expectations for growth, our ability to meet future financial targets may be adversely affected and our competitive position and our business and financial results could be harmed.

We are dependent on contract manufacturers with whom we do not have long-term supply contracts, and changes to or disruptions in those relationships or manufacturing processes, expected or unexpected, may result in delays that could cause us to lose revenues and damage our customer relationships.

We depend on independent contract manufacturers (each of which is a third-party manufacturer for numerous companies) to manufacture our products. Although we have contracts with our contract manufacturers, these contracts do not require them to manufacture our products on a long-term basis in any specific quantity or at any specific price. In addition, it is time-consuming and costly to qualify and implement additional contract manufacturer relationships. Therefore, if we fail to effectively manage our contract manufacturer relationships, which includes failing to provide accurate forecasts of our requirements, or if one or more of them experiences delays, disruptions, or quality control problems in our manufacturing operations, or if we had to change or add additional contract manufacturers or contract manufacturing sites, our ability to ship products to our customers could be delayed. We have experienced in the past and may experience in the future an increase in the expected time required to manufacture our products or ship products. Such delays could result in supply shortfalls that damage our ability to meet customer demand for those products and could cause our customers to purchase alternative products from our competitors. Also, the addition of manufacturing locations or contract manufacturers or the introduction of new products by us would increase the complexity of our supply chain management. Moreover, an increasing portion of our manufacturing is performed in China and other foreign countries and is therefore subject to risks associated with doing business outside of the United States, including the possibility of import tariffs imposed by the new administration.or regional conflicts. Each of these factors could adversely affect our business, financial condition and results of operations.


If we fail to accurately predict our manufacturing requirements, we could incur additional costs or experience manufacturing delays, which would harm our business.

We provide demand forecasts for our products to our contract manufacturers and original design manufacturers, who order components and plan capacity based on these forecasts. If we overestimate our requirements, our original design or contract manufacturers may assess charges, or we may have liabilities for excess inventory, each of which could negatively affect our gross margins. For example, in certain prior quarters, our gross margins were reduced as a result of an inventory charge resulting from inventory we held in excess of forecasted demand. In addition, some optical modules we use are experiencing faster product transitions than our other products, which increases the risk that we could have excess inventory of those modules. Conversely, because lead times for required materials and components vary significantly and depend on factors such as the specific supplier, contract terms, and the demand for each component at a given time, and because our contract manufacturers are third-party manufacturers for numerous other companies, if we underestimate our requirements, as we have in certain prior quarters with respect to certain products, our contract manufacturers may have inadequate time, materials, and/or components required to produce our products, which could increase costs or delay or interrupt manufacturing of our products resulting in delays in shipments and deferral or loss of revenues and negatively impacting customer satisfaction.

System security risks, data protection breaches, and cyber-attacks could compromise our and our customers’ proprietary information, disrupt our internal operations and harm public perception of our products, which could cause our business and reputation to suffer and adversely affect our stock price.

In the ordinary course of business, we store sensitive data, including intellectual property, personal data, our proprietary business information and proprietary business informationthat of our customers, suppliers and business partners on our networks. In addition, we store sensitive data through cloud-based services that may be hosted by third parties and in data center infrastructure maintained by third parties. The secure maintenance of this information is critical to our operations and business strategy. The growing cyber risk environment means that individuals, companies, and organizations of all sizes, including Juniper have been and are increasingly subject to the threat of intrusions on their networks and systems by a wide range of actors on an ongoing and regular basis. Despite our security measures, and those of our third-party vendors, our information technology and infrastructure has experienced breaches and may

be vulnerable in the future to penetrationbreach or attacks by computer programmers, hackers or sophisticated nation-state and nation-state supported actors or breached due to employee error or wrongful conduct, malfeasance, or other disruptions. If any breach or attack compromises our networks, creates system disruptions or slowdowns or exploits security vulnerabilities of our products, the information stored on our networks or those of our customers could be accessed and modified, publicly disclosed, lost or stolen, and we may be subject to liability to our customers, suppliers, business partners and others, and suffer reputational and financial harm. In addition, sophisticated hardware, components and operating system software and applications that we produce or procure from third parties may contain defects in design or manufacture, including "bugs", vulnerabilities and other problems that could unexpectedly interfere with the operation of our networks.networks or expose us or our products to cyber attacks. This can be true even for “legacy” products that have been determined to have reached an end of life engineering status but will continue to operate for a limited amount of time.

For example, in December 2015,When vulnerabilities are discovered, we disclosed that we identified unauthorized code in our ScreenOS security system that could allow a knowledgeable attacker to gain administrative access to NetScreen devicesevaluate the risk, apply patches or take other remediation actions as required and to decrypt VPN connections. Following the identificationnotify customers and suppliers when appropriate. All of the ScreenOS vulnerabilities, we launched an investigation into the matter, developed patched releases for the latest versions of ScreenOS and notified customers, all of which requiredthis requires significant time and attention from management and our employees. In addition, in April 2016, we made additional changes to ScreenOS in response to our additional analysis as a part of an update of ScreenOS. At this time, we do not have an estimate of third party costs related to the ScreenOS matter that could result from any third party claims brought against us, including, for example, indemnification for damages our customers may incur or actions instituted by governmental or regulatory entities that could result in fines or other penalties. Costs related to the ScreenOS matter, including the costs to resolve third party claims, may be material.

As a result of the ScreenOS matter, or any other actual or perceived breach of network security that occurs in our network or in the network of a customer of our products, regardless of whether the breach is attributable to our products, the market perception of the effectiveness of our products and our overall reputation could be harmed. As a large, well known provider of networking products, cyber attackers may specifically target our products or attempt to imitate us or our products in order to compromise a network. Because the techniques used by attackers, many of whom are highly sophisticated and well-funded, to access or sabotage networks change frequently and generally are not recognized until after they are used, we may be unable to anticipate or immediately detect these techniques or the vulnerabilities they have caused. This could impede our sales, manufacturing, distribution or other critical functions, which could have an adverse impact on our financial results. The economic costs to us to eliminate or alleviate cyber or other security problems, bugs, viruses, worms, malicious software systems and security vulnerabilities including the ScreenOS matter, could be significant and may be difficult to anticipate or measure, because the damage may differ based on the identity and motive of the attacker, which are often difficult to pinpoint. Additionally, we could be subject to regulatory investigations, potential fines and litigation in connection with a security breach or related issue and be liable to third parties for these types of breaches.

We are dependent on sole source and limited source suppliers for several key components, which makes us susceptible to shortages, quality issues or price fluctuations in our supply chain, and we may face increased challenges in supply chain management in the future.

We rely on single or limited sources of certain of our components. During periods of high demand for electronic products, component shortages are possible, and the predictability of the availability of such components may be limited. For example, some optical transceivers and memory components used in our networking solutions might experience extended lead times and higher pricing, given the demand in the market. Any future spike in growth in our business, or more likely in IT spending and the economy in general is likely to create greater short-term pressures on us and our suppliers to accurately forecast overall component demand and to establish optimal component inventories. If shortages or delays persist, the price of these components may increase, or the components may not be available at all. We may not be able to secure enough components at reasonable prices or of acceptable quality to build new products in a timely manner, and our revenues and gross margins could suffer until other sources can be developed. For example, from time to time,In addition, we have experienced, and from time-to-time may experience, component shortages or quality issues that resulted, or could result, in delays of product shipments and/or warranty or other claims. For example, in late 2016, we became aware of a defect in a clock-signal component from a third-party supplier that affected certain of our products and which resulted in remediation costs. As a result of this issue, we recorded a product cost of revenue charge that impacted our product gross margins for our fiscal year ended December 31, 2016 and three months ended March 31, 2017, and we may incur additional costs. We also currently purchase numerous key components, including ASICs and other semiconductor chips, from single or limited sources and many of our component suppliers are concentrated in China.China and Korea. In addition, there has been consolidation among certain suppliers of our components. For example, GLOBALFOUNDRIES recently acquired IBM’s semiconductor manufacturing business, Avago Technologies Limited recently acquired Broadcom Corporation, and Intel Corporation recently acquired Altera Corporation.Corporation and Broadcom Limited is proposing to acquire Qualcomm Incorporated. Consolidation among suppliers can result in the reduction of the number of independent suppliers of components available to us, which could negatively impact our ability to access certain component parts or the prices we have to pay for such parts. In addition, our suppliers may determine not to continue a business relationship with us for other reasons that may be beyond our control. Any disruptions to our supply chain could decrease our sales, earnings and liquidity or otherwise adversely affect our business and result in increased costs. Such a disruption could occur as a result of any number of events, including, but not limited to, increases in wages that drive up prices, the imposition of regulations, quotas or embargoes on key components, labor stoppages, transportation failures affecting the supply and shipment of materials and finished goods, the unavailability of raw materials, severe weather conditions, natural disasters, civil unrest, military conflicts, geopolitical developments, war or terrorism and disruptions in utility and other services.


The development of alternate sources for key components is time-consuming, difficult, and costly. In addition, the lead times associated with certain components are lengthy and preclude rapid changes in quantities and delivery schedules. Also, long-term supply and maintenance obligations to customers increase the duration for which specific components are required, which may further increase the risk of component shortages or the cost of carrying inventory. In the event of a component shortage or supply interruption from these suppliers, we may not be able to develop alternate or second sources in a timely manner. If we are unable to buy these components in quantities sufficient to meet our requirements on a timely basis, we will not be able to deliver products and services to our customers, which would seriously affect present and future sales, which would, in turn, adversely affect our business, financial condition, and results of operations.

In addition, the development, licensing, or acquisition of new products in the future may increase the complexity of supply chain management. Failure to effectively manage the supply of key components and products would adversely affect our business.

We rely on value-added and other resellers, as well as distribution partners, to sell our products, and disruptions to, or our failure to effectively develop and manage, our distribution channel and the processes and procedures that support it could adversely affect our ability to generate revenues from the sale of our products.

Our future success is highly dependent upon establishing and maintaining successful relationships with a variety of value-added and other reseller and distribution partners, including our worldwide strategic partners such as Ericsson, IBM, Dimension Data and NEC Corporation. The majority of our revenues are derived through value-added resellers and distributors, most of which also sell our competitors’ products, and some of which sell their own competing products. Our revenues depend in part on the performance of these partners. The loss of or reduction in sales to our resellers or distributors could materially reduce our revenues. For example, in 2011 and 2012, one of our OEM partners, Dell, acquired Force10 and SonicWall, both competitors of ours. As a result, Dell became increasingly competitive in certain areas, their resale of our products declined, and we ultimately terminated our OEM relationship with Dell. In addition, in 2016, Nokia Corporation merged with Alcatel-Lucent, a competitor of ours, and in 2015 Cisco recently announced a partnership with Ericsson, which is one of our existing partners. Our competitors may in some cases be effective in leveraging their market share positions or in providing incentives to current or potential resellers and distributors to favor their products or to prevent or reduce sales of our products. If we fail to develop and maintain relationships with our partners, fail to develop new relationships with value-added resellers and distributors in new markets, fail to expand the number of distributors and resellers in existing markets, fail to manage, train or motivate existing value-added resellers and distributors effectively, determine that we cannot continue to do business with these partners for any reason or if these partners are not successful in their sales efforts, sales of our products may decrease, and our business, financial condition, and results of operations would suffer.

In addition, we recognize a portion of our revenues based on a sell-through model using information provided by our distributors. If those distributors provide us with inaccurate or untimely information, the amount or timing of our revenues could be adversely impacted.

We are also vulnerable to third parties who illegally distribute or sell counterfeit, stolen or unfit versions of our products, which has happened in the past and could happen in the future. Such sales could have a negative impact on our reputation and business.

Further, in order to develop and expand our distribution channel, we must continue to offer attractive channel programs to potential partners and scale and improve our processes and procedures that support the channel. As a result, our programs, processes and procedures may become increasingly complex and inherently difficult to manage. We have previously entered into OEM agreements with partners pursuant to which they rebrand and resell our products as part of their product portfolios. These types of relationships are complex and require additional processes and procedures that may be challenging and costly to implement, maintain and manage. Our failure to successfully manage and develop our distribution channel and the programs, processes and procedures that support it could adversely affect our ability to generate revenues from the sale of our products. We also depend on our global channel partners to comply with applicable legal and regulatory requirements. To the extent that they fail to do so, that could have a material adverse effect on our business, operating results, and financial condition.

Our ability to process orders and ship products in a timely manner is dependent in part on our business systems and performance of the systems and processes of third parties such as our contract manufacturers, suppliers, data center providers or other partners, as well as the interfaces between our systems and the systems of such third parties. If our systems, the systems and processes of those third parties, or the interfaces between them experience delays or fail, our business processes and our ability to build and ship products could be impacted, and our financial results could be harmed.

Some of our business processes depend upon our information technology, or IT, systems, the systems and processes of third parties, and the interfaces of our systems with the systems of third parties. For example, our order entry system feeds information into the systems of our contract manufacturers, which enables them to build and ship our products. If those systems fail orwe are interrupted, our processes may function at a diminished level or not at all. This could negatively impact our ability to ship products or otherwise operate our business, and our financial results could be harmed. For example, although it did not adversely affect our shipments, an earthquake in late December of 2006 disrupted our communications with China, where a significant part of our manufacturing occurs.

We are also in the process of further consolidating our on-site data centers to the cloud and to off-site facilities that are hosted and controlled by third-parties. These cloud providers and off-site facilities are vulnerable to damage, interruption or performance problems from earthquakes, hurricanes, floods, fires, power loss, telecommunications failures, equipment failure, adverse events caused by operator error and similar events. In addition,

because we lease our cloud storage space and off-site data center facilities, we cannot be assured that we will be able to expand our data center infrastructure to meet user demand in a timely manner, or on favorable economic terms. If we have issues receiving and processing data, this may delay our ability to provide products and services to our customers and damage our business. We also rely upon the performance of the systems and processes of our contract manufacturers to build and ship our products. If those systems and processes experience interruption or delay, our ability to build and ship our products in a timely manner may be harmed. For example, we have experienced instances where our contract manufacturers were not able to ship products in the time periods expected by us, which prevented us from meeting our commitments to our customers. If we are not able to ship our products or if product shipments are delayed, our ability to recognize revenue in a timely manner for those products would be affected and our financial results could be harmed.

Integration of acquisitions could disrupt our business and harm our financial condition and stock price and may dilute the ownership of our stockholders.

We have made, and may continue to make, acquisitions in order to enhance our business. For example, in December2017 we acquired Cyphort Inc. and in 2016, we acquired AppFormix Inc.; in August 2016, we acquired, Aurrion, Inc.; and in April 2016, we acquired BTI Systems Inc.; in 2014, we acquired WANDL, Inc.; and in 2012, we acquired Contrail Systems Inc. and Mykonos Software, Inc. Acquisitions involve numerous risks, including, but not limited to, problems combining the purchased operations, technologies or products, unanticipated costs and liabilities, diversion of management's attention from our core businesses, adverse effects on existing business relationships with suppliers and customers, risks associated with entering markets in which we have no or limited prior experience, and potential loss of key employees. There can be no assurance that we will be able to integrate successfully any businesses, products, technologies, or personnel that we might acquire. The integration of businesses that we may acquire is likely to be a complex, time-consuming, and expensive process and we may not realize the anticipated revenues or other benefits associated with our acquisitions if we fail to successfully manage and operate the acquired business. If we fail in any acquisition integration efforts and are unable to efficiently operate as a combined organization utilizing common information and communication systems, operating procedures, financial controls, and human resources practices, our business, financial condition, and results of operations may be adversely affected.


In connection with certain acquisitions, we may agree to issue common stock or assume equity awards that dilute the ownership of our current stockholders, use a substantial portion of our cash resources, assume liabilities, record goodwill and amortizable intangible assets that will be subject to impairment testing on a regular basis and potential periodic impairment charges, incur amortization expenses related to certain intangible assets, and incur large and immediate write-offs and restructuring and other related expenses, all of which could harm our financial condition and results of operations.

Telecommunications, cable and cloud service provider companies and our other large customers generally require onerous terms and conditions in our contracts with them. As we seek to sell more products to such customers, we may be required to agree to terms and conditions that could have an adverse effect on our business or ability to recognize revenues.

Telecommunications, cable and cloud service provider companies, which comprise a significant portion of our customer base, and other large companies, generally have greater purchasing power than smaller entities and, accordingly, often request and receive more favorable terms from suppliers. For example, our customers France Telecom-Orange and Deutsche Telekom AG have formed a company for the purpose of purchasing products from, and negotiating more favorable contractual terms with, suppliers. As we seek to sell more products to this class of customer, we may be required to agree to such terms and conditions, which may include terms that affect the timing of our ability to recognize revenue, increase our costs and have an adverse effect on our business, financial condition, and results of operations. Consolidation among such large customers can further increase their buying power and ability to require onerous terms.

In addition, service providers have purchased products from other vendors who promised but failed to deliver certain functionality and/or had products that caused problems or outages in the networks of these customers. As a result, these customers may request additional features from us and require substantial penalties for failure to deliver such features or may require substantial penalties for any network outages that may be caused by our products. These additional requests and penalties, if we are required to agree to them, may require us to defer revenue recognition from such sales, which may negatively affect our business, financial condition and results of operations. In addition, increased patent litigation brought against customers by non-practicing entities in recent years, may result, and in some cases has resulted, in customers requesting or requiring vendors to absorb a portion of the costs of such litigation or providing broader indemnification for litigation, each of which could increase our expenses and negatively affect our business, financial condition and results of operations.

We are a party to lawsuits, investigations, proceedings, and other disputes, which are costly to defend and, if determined adversely to us, could require us to pay fines or damages, undertake remedial measures or prevent us from taking certain actions, any or all of which could harm our business, results of operations, financial condition or cash flows.

We, and certain of our current and former officers and current and former members of our Board of Directors, have been or are subject to various lawsuits. We have been served with lawsuits related to employment matters, commercial transactions and patent infringement, as well as securities laws. As noted in Note 16, Commitments and Contingencies, in Notes to Consolidated Financial Statements of this Report, under the heading of “Legal Proceedings”, the U.S. Securities and Exchange Commission, or the SEC, is conducting, and the U.S. Department of Justice, or the DOJ, arewas previously conducting, investigations into possible violations by the Company of the U.S. Foreign Corrupt Practices Act, or the FCPA, in a number of countries. The investigations relate to certain of the Company’s marketing practices and whether the Company or any third party on behalf of the Company gave money or anything else of value to any government official in violation of the FCPA. The Company’s Audit Committee, with the assistance of independent advisors, has been investigating and conducting a thorough review of possible violations of the FCPA, and has made recommendations for remedial measures, including employee disciplinary actions in foreign jurisdictions, which the Company has implemented and continues to implement. Litigation and investigations are inherently uncertain. We therefore cannot predict the duration, scope, outcome or consequences of litigation and government investigations. In connection with any government investigations, including those in which we are currently involved as described above, if the government takes action against us or we agree to settle the matter, we may be required to pay substantial fines and incur other sanctions, which may be material, and suffer reputational harm. The lawsuits and investigations are expensive and time-consuming to defend, settle, and/or resolve, and may require us to implement certain remedial measures that could prove costly or disruptive to our business and operations. The unfavorable resolution of one or more of these matters could have a material adverse effect on our business, results of operations, financial condition or cash flows.

We are a party to litigation and claims regarding intellectual property rights, resolution of which may be time-consumingtime-consuming and expensive, as well as require a significant amount of resources to prosecute, defend, or make our products non-infringing.

Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. We expect that infringement claims may increase as the number of products and competitors in our market increases and overlaps occur. Third parties have asserted and may in the future assert claims or initiate litigation related to patent, copyright, trademark, and other intellectual property rights to technologies and related standards that are relevant to our products. The asserted claims and/or initiated litigation may include claims against us or our manufacturers,

suppliers, partners, or customers, alleging that our products or services infringe proprietary rights. In addition, increased patent litigation brought by non-practicing entities in recent years may result, and in some cases has resulted, in our customers requesting or requiring us to absorb a portion of the costs of such litigation or providing broader indemnification for litigation, each of which could increase our expenses and negatively affect our business, financial condition and results of operations. Regardless of the merit of these claims, they have been and can be time-consuming, result in costly litigation, and may require us to develop non-infringing technologies, enter into license agreements, or cease engaging in certain activities or offering certain products or services. Furthermore, because of the potential for high awards of damages or injunctive relief that are not necessarily predictable, even arguably unmeritorious claims may be settled for significant amounts of money. If any infringement or other intellectual property claim made against us or anyone we are required to indemnify by any third-party is successful, if we are required to settle litigation for significant amounts of money, if we fail to develop non-infringing technology, if we incorporate infringing technology in our products or if we license required proprietary rights at material expense, our business, financial condition, and results of operations could be materially and adversely affected.

Regulation of our industry in general and the telecommunications industry in particular could harm our operating results and future prospects.

We are subject to laws and regulations affecting the sale of our products in a number of areas. For example, some governments have regulations prohibiting government entities from purchasing security products that do not meet specified indigenous certification criteria, even though those criteria may be in conflict with accepted international standards. Other regulations that may negatively impact our business include country of origin regulations. These types of regulations are in effect or under consideration in several jurisdictions where we do business.

The Dodd-Frank Wall Street Reform and Consumer Protection Act includes disclosure requirements applicable to public companies regarding the use of “conflict minerals” mined from the Democratic Republic of Congo and adjoining countries, which we refer to collectively as the DRC, and procedures regarding a manufacturer's efforts to prevent the sourcing of such “conflict minerals.” These minerals are present in our products. SEC rules implementing these requirements may have the effect of reducing the pool of suppliers who can supply DRC “conflict free” components and parts, and we may not be able to obtain DRC conflict free products or supplies in sufficient quantities for our operations. Since our supply chain is complex, we may face reputational challenges with our customers, stockholders and other stakeholders if we are unable to sufficiently verify the origins for the "conflict minerals" used in our products. In addition, the European Union reached agreement in late 2016 on a EU-wide conflict minerals rule under which most EU importers of tin, tungsten, tantalum, gold and their ores will have to conduct due diligence to

ensure the minerals do not originate from conflict zones and do not fund armed conflicts. Large manufacturers also will have to disclose how they plan to monitor their sources to comply with the rules. The regulation is expected to bewas adopted in 2017 with compliance required by 2021.

In addition, environmental laws and regulations relevant to electronic equipment manufacturing or operations, including laws and regulations governing the hazardous material content of our products and laws relating to the collection of and recycling of electrical and electronic equipment, may adversely impact our business and financial condition. These laws and regulations include, among others, the European Union, or EU, Restriction on the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Directive, or RoHS. The EU RoHS and the similar laws of other jurisdictions limit the content of certain hazardous materials, such as lead, mercury, and cadmium, in the manufacture of electricalelectronic equipment, including our products. Currently, our products comply with the EU RoHS requirements. However, certain exemptions are scheduled to lapse, or have lapsed, including an exemption for lead in network infrastructure equipment upon which we and our competitors had relied, which expired in July 2016.lapsed. The lapse of thisany exemption, further changes to this or other laws, or passage of similar laws in the EU or other jurisdictions, would require us to cease selling non-compliant products in the EU and to reengineer our products to use components compatible with these regulations. This reengineering and component substitution could result in additional costs to us, disrupt our operations or logistics, and result in an adverse impact on our operating results. In addition, in validating the compliance of our products with applicable hazardous materials restrictions, we rely substantially on affirmations by our component suppliers as to the compliance of their products with respect to those same restrictions. Failure by our component suppliers to furnish accurate and timely information could subject us to penalties or liability for violation of such hazardous materials restrictions, interrupt our supply of products to the EU, and result in our customers refusing or being unable to purchase our products. Additionally, the EU and a number of other countries have adopted regulations requiring producers of electrical and electronic equipment to assume certain responsibilities for collecting, treating, recycling and disposing of products when they have reached the end of their useful life. Finally, the EU REACH regulations regulate the handling of certain chemical substances that may be used in our products.

In addition, as a contractor and subcontractor to U.S. government departments and agencies, we are subject to Federal regulations pertaining to our IT systems. For instance, as a subcontractor to the U.S. Department of Defense, or DOD, the Defense Federal Acquisition Regulation Supplement (DFARS) required that our IT systems comply with the security and privacy controls described in National Institute of Standards and Technology Special Publication 800-171, or NIST SP 800-171 no later than December 31, 2017. The traditionalDFARS also requires that we flow the security control requirement down to certain of our own subcontractors. Failure to comply with these requirements could result in a loss of Federal government business, subject us to claims or other remedies for non-compliance and negatively impact our business, financial condition, and results of operations.

The telecommunications industry is highly regulated, and our business and financial condition could be adversely affected by changes in regulations relating to the Internet telecommunications industry. Currently, there are few laws or regulations that apply directly to access to or commerce on IP networks, but future regulations could include sales taxes on products sold via the Internet and Internet service provider access charges. We could be adversely affected by regulation of IP networks and commerce in any country where we market equipment and services to service providers or cloud provider companies. Regulations governing

the range of services and business models that can be offered by service providers or cloud provider companies could adversely affect those customers' needs for products. For instance, in December 2017, the U.S. Federal Communications Commission has issuedrepealed its 2015 regulations governing aspects of fixed broadband networks and wireless networks. These regulations, which were challengedThis change in court, and which the new Federal Communications Commission leadership is considering removing or modifying,regulatory treatment of networks might impact service provider and cloud provider business models and, as such, providers' needs for Internet telecommunications equipment and services. Also, many jurisdictions are evaluating or implementing regulations relating to cyber security, supply chain integrity, privacy and data protection, any of which can affect the market and requirements for networking and security equipment.

The adoption and implementation of additional regulations could reduce demand for our products, increase the cost of building and selling our products, result in product inventory write-offs, impact our ability to ship products into affected areas and recognize revenue in a timely manner, require us to spend significant time and expense to comply, and subject us to fines and civil or criminal sanctions or claims if we were to violate or become liable under such regulations. Any of these impacts could have a material adverse effect on our business, financial condition, and results of operations.


Governmental regulations and economic sanctions affecting the import or export of products generally or affecting products containing encryption capabilities could negatively affect our revenues and operating results.

The United States and various foreign governments have imposed controls and restrictions on the import or export of, among other things, our products that contain or use encryption technology. Most of our products contain or use encryption technology and, consequently, are subject to such controls, requirements and restrictions. In addition, from time to time, governmental agencies have proposed additional regulationCertain governments also control importation and in-country use of encryption technology,items and technology. The scope, nature and severity of such as requiringcontrols vary widely across different countries and may change frequently over time. For example, China has promulgated cybersecurity regulations and published a new draft export law affecting networking products that may impair our ability to profitably market and sell our products in China. Certain countries’ encryption control regimes may significantly limit our ability to sell major lines of our products in those countries.

Certain governments also impose special local content, certification, notifications, review oftesting, source code limiting the encryption features or thereview, escrow and governmental recovery of private encryption keys. For example, China has proposed new conditionskeys, or feature requirements on eligibilitynetwork equipment for purposes of encryption products for purchasegovernment procurements. Similar requirements may also be imposed in procurements by government and certain non-government organizations. India recently proposed and then withdrew regulations imposing serious conditions on the use of encryption in telecommunications products. We sell our products to both commercial customers and, directly and indirectly, to governments around the world.state owned entities (“SOE’s”). Our ability to sell into substantial government and SOE markets (whether or not the products we sell include encryption) is vulnerable to changes in applicable government procurement regulations, any associated local content requirements and changes in the government’s interpretation of such regulations. In addition, the U.S. government has broader sanctions and embargoes that generally forbid supply of most items to or involving certain countries, territories, governments, legal entities and individuals, including recent restrictions imposed by the U.S. and EU on exports to Russia and Ukraine. We have implemented systems to detect and prevent sales into these countries or to prohibited entities or individuals, but there can be no assurance that they will always be effective.

Governmental regulation of encryption or IP networking technology and regulation of imports or exports, or our failure to obtain required import or export approval for our products, or related economic sanctions could harm our international and domestic sales and adversely affect our revenues and operating results. In addition, failure to comply with such regulations could result in harm to our reputation and ability to compete in international markets, penalties, costs, seizure of assets (including source code) and restrictions on import or export privileges or adversely affect sales to government agencies or government-funded projects.

Our actual or perceived failure to adequately protect personal data could adversely affect our business, financial condition and results of operations.

A variety of state, national, foreign, and international laws and regulations apply to the collection, use, retention, protection, disclosure, transfer, and other processing of personal data. These privacy- and data protection-related laws and regulations are evolving, with new or modified laws and regulations proposed and implemented frequently and existing laws and regulations subject to new or different interpretations. Compliance with these laws and regulations can be costly and can delay or impede the development and offering of new products and services.

For example, we previously relied upon adherence to the U.S. Department of Commerce’s Safe Harbor Privacy Principles and compliance with the U.S.-EU Safe Harbor Framework, which we refer to as the Safe Harbor, agreed to by the U.S. Department of Commerce and the EU. The Safe Harbor, which established means for legitimizing the transfer of personal data by U.S. companies from the European Economic Area, or EEA, to the U.S., was invalidated in 2015 by a decision of the European Court of Justice, or the ECJ. Now that the EU and U.S. have implemented a successor privacy framework called the Privacy Shield, we are reviewing and documenting our practices required to obtain certification under the Privacy Shield, in addition to entering into EU Model Contracts with our vendors where appropriate and feasible in anticipation of the possibility that either the Privacy Shield or EU Model Contracts may be legally challenged or voided like Safe Harbor in an uncertain political environment. In addition, the EU General Data Protection Regulation, which goes into full effect in May 2018, is expected to result in substantial changes to our compliance obligations, including contractual requirements for data transfers outside the EEA, and a significant increase in potential administrative fines for non-compliance. Similarly, the June 2016 approval by voters in the United Kingdom, or U.K., of a referendum to leave the EU could require us to make additional changes to the way we conduct our business and transmit data between the U.S., U.K., EU and the EU.

rest of the world.

Our actual or alleged failure to comply with applicable laws and regulations, or to protect personal data, could result in enforcement actions, significant penalties or other legal action against us or our customers or suppliers, which could result in negative publicity, increase our operating costs, subject us to claims or other remedies and have a material adverse effect on our business, financial condition, and results of operations.


Our ability to develop, market, and sell products could be harmed if we are unable to retain or hire key personnel.

Our future success depends upon our ability to recruit and retain the services of executive, engineering, sales and marketing, and support personnel. The supply of highly qualified individuals, in particular engineers in very specialized technical areas, or sales people specializing in the service provider and enterprise markets,with specialized industry expertise, is limited and competition for such individuals is intense. None of our officers or key employees is bound by an employment agreement for any specific term. The loss of the services of any of our key employees, the inability to attract or retain personnel in the future or delays in hiring required personnel, engineers and sales people, and the complexity and time involved in replacing or training new employees, could delay the development and introduction of new products, and negatively impact our ability to market, sell, or support our products.

A number of our team members are foreign nationals who rely on visas and entry permits in order to legally work in the United States and other countries.  In recent years, the United States has increased the level of scrutiny in granting H-1(B), L-1 and other business visas.  In addition, the current U.S. administration has indicated that immigration reform is a priority. Compliance with United States immigration and labor laws could require us to incur additional unexpected labor costs and expenses or could restrain our ability to retain skilled professionals.  Any of these restrictions could have a material adverse effect on our business, results of operations and financial conditions.

Our financial condition and results of operations could suffer if there is an additional impairment of goodwill or other intangible assets with indefinite lives.

We are required to test intangible assets with indefinite lives, including goodwill, annually or more frequently if certain circumstances change that would more likely than not reduce the fair value of a reporting unit and intangible assets below their carrying values. As of December 31, 2016,2017, our goodwill was $3,081.7$3,096.2 million and intangible assets with indefinite lives was $49.0 million. When the carrying value of a reporting unit’s goodwill exceeds its implied fair value of goodwill, or if the carrying amount of an intangible asset with an indefinite life exceeds its fair value, a charge to operations is recorded. Either event would result in incremental expenses for that quarter, which would reduce any earnings or increase any loss for the period in which the impairment was determined to have occurred.

In the past, we recorded a goodwill impairment charge of $850.0 million due to the underperformance of our Security reporting unit and product rationalizations.

In recent years,From time to time, economic weakness has contributed to extreme price and volume fluctuations in global stock markets that have reduced the market price of many technology company stocks, including ours. Declines in our level of revenues due to restructuring or cost reductions or declines in our operating margins, or sustained declines in our stock price, increase the risk that goodwill and intangible assets with indefinite lives may become impaired in future periods.

OurDuring the three months ended June 30, 2017, we concluded that there were sufficient indicators to require us to perform an interim goodwill impairment analysis on our Security reporting unit. Based on our analysis, we determined that our Security reporting unit’s goodwill was not impaired. However, our goodwill impairment analysis is sensitive to changes in key assumptions used in our analysis, such as expected future cash flows, the degree of volatility in equity and debt markets, and our stock price. If the assumptions used in our analysis are not realized, it is possible that an impairment charge may need to be recorded in the future. We cannot accurately predict the amount and timing of any impairment of goodwill or other intangible assets. However, any such impairment would have an adverse effect on our results of operations.

Changes in effective tax rates or adverse outcomes resulting from examination of our income or other tax returns could adversely affect our results.

Our future effective tax rates could be subject to volatility or adversely affected by the following: earnings being lower than anticipated in countries where we have lower statutory rates and higher than anticipated earnings in countries where we have higher statutory rates; changes in the valuation of our deferred tax assets and liabilities; expiration of, or lapses in, the R&D tax credit laws applicable to us; transfer pricing adjustments related to certain acquisitions, including the license of acquired intangibles under our intercompany R&D cost sharing arrangement; costs related to intercompany restructuring; tax effects of share-based compensation; challenges to our methodologies for valuing developed technology or intercompany arrangements; limitations on the deductibility of net interest expense; or changes in tax laws, regulations, accounting principles, or interpretations thereof. OnThe Tax Cuts and Jobs Act of 2017 (the “Tax Act”), which was signed into law on December 22, 2017, makes significant changes to the taxation of U.S. business entities that will have a meaningful impact to our provision for income taxes. These changes include a reduction to the federal corporate income tax rate, the current taxation of certain foreign earnings, the imposition of base-erosion prevention measures which may limit the deduction of certain transfer pricing payments, and possible limitations on the deductibility of net interest expense or corporate debt obligations. Accounting for the income tax effects of the Tax Act requires significant

judgements and estimates that are based on current interpretations of the Tax Act and could be affected by changing interpretations of the Act, as well as additional legislation and guidance around the Act. Any refinements to these provisional estimates are difficult to predict and could impact our results.

Furthermore, on October 5, 2015, the Organisation for Economic Co-operation and Development, or OECD, an international association of 35 countries including the U.S., published final proposals under its Base Erosion and Profit Shifting, or BEPS, Action Plan. The BEPS Action Plan includes fifteen Actions to address BEPS

in a comprehensive manner and represents a significant change to the international corporate tax landscape. These proposals, as adopted by countries, may increase tax uncertainty and adversely affect our provision for income taxes. Furthermore, the current U.S. administration and key members of Congress have made public statements indicating that tax reform is a priority. Certain changes to U.S. tax laws, including limitations on the ability to defer U.S. taxation on earnings outside of the United States until those earnings are repatriated to the United States, could affect the tax treatment of our foreign earnings. In addition, we are subject to the continuous examination of our income tax returns by the Internal Revenue Service, or IRS, and other tax authorities. It is possible that tax authorities may disagree with certain positions we have taken and any adverse outcome of such a review or audit could have a negative effect on our financial position and operating results. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes, but the determination of our worldwide provision for income taxes and other tax liabilities requires significant judgment by management, and there are transactions where the ultimate tax determination is uncertain. Although we believe that our estimates are reasonable, the ultimate tax outcome may differ from the amounts recorded in our consolidated financial statements and may materially affect our financial results in the period or periods for which such determination is made. There can be no assurance that the outcomes from continuous examinations will not have an adverse effect on our business, financial condition, and results of operations.

We may face difficulties enforcing our proprietary rights, which could adversely affect our ability to compete.

We generally rely on a combination of patents, copyrights, trademarks, and trade secret laws and contractual restrictions on disclosure of confidential and proprietary information, to establish and maintain proprietary rights in our technology and products. Although we have been issued numerous patents and other patent applications are currently pending, there can be no assurance that any of our patent applications will result in issued patents or that any of our patents or other proprietary rights will not be challenged, invalidated, infringed or circumvented or that our rights will, in fact, provide competitive advantages to us or protect our technology, any of which could result in costly product redesign efforts, discontinuance of certain product offerings and other competitive harm.

In addition, despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or obtain and use information that we regard as proprietary. We generally enter into confidentiality or license agreements with our employees, consultants, vendors, and customers, and generally limit access to and distribution of our proprietary information. However, we cannot assure you that we have entered into such agreements with all parties who may have or have had access to our confidential information or that the agreements we have entered into will not be breached. We cannot guarantee that any of the measures we have taken will prevent misappropriation of our technology.

Furthermore, the laws of some foreign countries may not protect our proprietary rights to the same extent as do the laws of the United States. The outcome of any actions taken in these foreign countries may be different than if such actions were determined under the laws of the United States. Although we are not dependent on any individual patents or group of patents for particular segments of the business for which we compete, if we are unable to protect our proprietary rights in a market, we may find ourselves at a competitive disadvantage to others who need not incur the substantial expense, time, and effort required to create innovative products that have enabled our success.

We are subject to risks arising from our international operations, which may adversely affect our business, financial condition, and results of operations.

We derive a substantial portion of our revenues from our international operations, and we plan to continue expanding our business in international markets. We conduct significant sales and customer support operations directly and indirectly through our distributors and VARs in countries throughout the world and depend on the operations of our contract manufacturers and suppliers that are located outside of the United States. In addition, a portion of our R&D and our general and administrative operations are conducted outside the United States. In some countries, we may experience reduced intellectual property protection.

As a result of our international operations, we are affected by economic, business regulatory, social, and political conditions in foreign countries, including the following:

changes in general IT spending,

the imposition of government controls, inclusive of critical infrastructure protection;


changes or limitations in trade protection laws or other regulatory requirements, which may affect our ability to import or export our products from various countries;

laws that restrict sales of products developed or manufactured outside of the country;

varying and potentially conflicting laws and regulations;

fluctuations in local economies;

wage inflation or a tightening of the labor market;

tax policies that could have a business impact;

potential import tariffs imposed by the United States;States and the possibility of reciprocal tariffs by foreign countries;

data privacy rules and other regulations that affect cross border data flow; and

the impact of the following on customer spending patterns: political considerations, unfavorable changes in tax treaties or laws, natural disasters, epidemic disease, labor unrest, earnings expatriation restrictions, misappropriation of intellectual property, military actions, acts of terrorism, political and social unrest and difficulties in staffing and managing international operations.

Any or all of these factors could have a material adverse impact on our business, financial condition, and results of operations.

In addition, the June 2016 approval by voters in the U.K. of a referendum to leave the EU and the U.K.’s formal initiation of the exit process in March 2017, commonly referred to as Brexit, has caused, and may continue to cause, uncertainty in the global markets. The U.K.’s proposed exit from the EU, if implemented, will take some period of time to complete and could result in regulatory changes that impact our business. For example, changes to the way service providers conduct business and transmit data between the U.K. and the EU could require us to make changes to the way we handle customer data. We will also review the impact of any resulting changes to EU or U.K. law that could affect our operations, such as labor policies, financial planning, product manufacturing, and product distribution. Political and regulatory responses to the vote are still developing and we are in the process of assessing the impact the vote may have on our business as more information becomes available. Nevertheless, because we conduct business in the EU, including the U.K., any of the effects of Brexit, including those we cannot anticipate, could have a material adverse effect on our business, operating results, financial condition and cash flows.

Moreover, local laws and customs in many countries differ significantly from or conflict with those in the United States or in other countries in which we operate. In many foreign countries, it is common for others to engage in business practices that are prohibited by our internal policies and procedures or U.S. regulations applicable to us. There can be no assurance that our employees, contractors, channel partners, and agents will not take actions in violation of our policies and procedures, which are designed to ensure compliance with U.S. and foreign laws and policies. Violations of laws or key control policies by our employees, contractors, channel partners, or agents could result in termination of our relationship, financial reporting problems, fines, and/or penalties for us, or prohibition on the importation or exportation of our products, and could have a material adverse effect on our business, financial condition and results of operations.

Our products are highly technical and if they contain undetected defects, errors or malware or do not meet customer quality expectations, our business could be adversely affected, and we may be subject to additional costs or lawsuits or be required to pay damages in connection with any alleged or actual failure of our products and services.

Our products are highly technical and complex, are critical to the operation of many networks, and, in the case of our security products, provide and monitor network security and may protect valuable information. Our products have contained and may contain one or more undetected errors, defects, malware, or security vulnerabilities. These errors may arise from hardware or software we produce or procure from third parties. Some errors in our products may only be discovered after a product has been installed and used by end-customers. For example, in December 2015, we disclosed that we identified unauthorized code in ScreenOS that could allow a knowledgeable attacker to gain administrative access to NetScreen devices and to decrypt VPN connections.

Any errors, defects, malware or security vulnerabilities discovered in our products after commercial release could result in monetary penalties, negative publicity, loss of revenues or delay in revenue recognition, loss of customers, loss of future business and

reputation, penalties, and increased service and warranty cost, any of which could adversely affect our business, financial condition, and results of operations. In addition, in the event an error, defect, malware, or vulnerability is attributable to a component supplied by a third-party vendor, we may not be able to recover from the vendor all of the costs of remediation that we may incur. In addition, we could face claims for product liability, tort, or breach of warranty or indemnification. Defending a lawsuit, regardless of its merit, is costly and may divert management’s attention. If our business liability insurance coverage is inadequate, or future coverage is unavailable on acceptable terms or at all, our financial condition and results of operations could be harmed. Moreover, if our products fail to satisfy our customers' quality expectations for whatever reason, the perception of and the demand for our products could be adversely affected.

We are exposed to fluctuations in currency exchange rates, which could negatively affect our financial condition and results of operations.

Because a substantial portion of our business is conducted outside the United States, we face exposure to adverse movements in non-U.S. currency exchange rates. These exposures may change over time as business practices evolve and could have a material adverse impact on our financial condition and results of operations.

The majority of our revenues and expenses are transacted in U.S. Dollars. We also have some transactions that are denominated in foreign currencies, primarily the British Pound, Chinese Yuan, Euro, and Indian Rupee and Japanese Yen related to our sales and service operations outside of the United States. An increase in the value of the U.S. Dollar could increase the real cost to our customers of our products in those markets outside the United States in which we sell in U.S. Dollars. This could negatively affect our ability to meet our customers' pricing expectations in those markets and may result in erosion of gross margin and market share. A weakened U.S. Dollar could increase the cost of local operating expenses and procurement of raw materials to the extent we must purchase components in foreign currencies.

Currently, we hedge only those currency exposures associated with certain assets and liabilities denominated in nonfunctional currencies and periodically hedge anticipated foreign currency cash flows. The hedging activities undertaken by us are intended to offsetflows, with the aim of offsetting the impact of currency fluctuations on certain nonfunctional currency assets and liabilities.these exposures. However, such attempts to offset the impact of currency fluctuations arehedge activities can be costly, and no amount of hedging can be effective againstcannot fully offset all circumstances,risks, including

long-term declines or appreciation in the value of the U.S. Dollar. If our attempts to hedge against these risks are not successful, or if long-term declines or appreciation in the value of the U.S. Dollar persist, our financial condition and results of operations could be adversely impacted.

Approximately $125 millionA portion of the transaction consideration we received from the divestiture of our Junos Pulse product portfolio is in the form of a non-contingent seller promissory note and we may not receive the amount owed to us (including accrued interest), including in the time frame contemplated, by the buyer under the note.

In the fourth quarter of fiscal 2014, we completed the sale of our Junos Pulse product portfolio to an affiliate of Siris Capital, a private equity firm, for total consideration of $230.7 million, of which $105.7 million was in cash, net of a $19.3 million working capital adjustment, and $125.0 million was in the form of an 18-month non-contingent interest-bearing promissory note issued to the Company. On October 2, 2015, the Companywe and the issuer of the promissory note agreed to modify the original terms of the note to extend the maturity date from April 1, 2016 to December 31, 2018. On May 1, 2017, we received a principal payment in the amount of $75.0 million and outstanding interest on the note and we and the issuer agreed to further amend the terms of the note with respect to the remaining approximately $58.0 million to, among other things, extend the maturity date from December 31, 2018 to September 30, 2022, provide that interest due can be paid in kind by increasing the outstanding principal amount of the note and subordinate the note to other debt issued by senior lenders. Since approximately $125.0 milliona portion of the transaction consideration is in the form of a non-contingent seller promissory note and the note is subordinated to debt issued by senior lenders, there is the risk that we may not receive the amount owed to us (including accrued interest), including in the time frame contemplated, under the note. In the event that the promissory note is not repaid on the terms we contemplate, any collection or restructuring efforts we undertake may be costly and require significant time and attention from our management and there is no guarantee that we will be able to recover the amounts owed to us in full.

If we fail to adequately evolve our financial and managerial control and reporting systems and processes, our ability to manage and grow our business will be negatively affected.

Our ability to successfully offer our products and implement our business plan in a rapidly evolving market depends upon an effective planning and management process. We will need to continue to improve our financial and managerial control and our reporting systems and procedures in order to manage our business effectively in the future. If we fail to effectively improve our systems and processes or we fail to monitor and ensure that these systems and processes are being used correctly, our ability to manage our business, financial condition, and results of operations may be negatively affected.

Our products are highly technical and if they contain undetected defects, errors or malware or do not meet customer quality expectations, our business could be adversely affected, and we may be subject to additional costs or lawsuits or be required to pay damages in connection with any alleged or actual failure of our products and services.

Our products are highly technical and complex, are critical to the operation of many networks, and, in the case of our security products, provide and monitor network security and may protect valuable information. Our products have contained and may contain one or more undetected errors, defects, malware, or security vulnerabilities. Some errors in our products may only be discovered after a product has been installed and used by end-customers. For example, in December 2015, we disclosed that we identified unauthorized code in ScreenOS that could allow a knowledgeable attacker to gain administrative access to NetScreen devices and to decrypt VPN connections.

Any errors, defects, malware or security vulnerabilities discovered in our products after commercial release could result in monetary penalties, loss of revenues or delay in revenue recognition, loss of customers, loss of future business and reputation, penalties, and increased service and warranty cost, any of which could adversely affect our business, financial condition, and results of operations. Following the identification of the ScreenOS vulnerabilities, we launched an investigation into the matter, developed patched releases for the latest versions of ScreenOS and notified customers, all of which required significant time and attention from management and our employees. In addition, in the event an error, defect, malware, or vulnerability is attributable to a component supplied by a third-party vendor, we may not be able to recover from the vendor all of the costs of remediation that we may incur. In addition, we could face claims for product liability, tort, or breach of warranty or indemnification. Defending a lawsuit, regardless of its merit, is costly and may divert management’s attention. If our business liability insurance coverage is inadequate, or future coverage is unavailable on acceptable terms or at all, our financial condition and results of operations could be harmed. Moreover, if our products fail to satisfy our customers' quality expectations for whatever reason, the perception of and the demand for our products could be adversely affected.

If our products do not interoperate with our customers’ networks, installations will be delayed or cancelled and could harm our business.

Our products are designed to interface with our customers’ existing networks, each of which have different specifications and utilize multiple protocol standards and products from other vendors. Many of our customers’ networks contain multiple generations of products that have been added over time as these networks have grown and evolved. Our products must interoperate with many or all of the products within these networks as well as future products in order to meet our customers’ requirements. If we find errors in the existing software or defects in the hardware used in our customers’ networks, we may need to modify our software or hardware to fix or overcome these errors so that our products will interoperate and scale with the existing software and hardware, which could be costly and could negatively affect our business, financial condition, and results of operations. In addition, if our

products do not interoperate with those of our customers’ networks, demand for our products could be adversely affected or orders for our products could be cancelled. This could hurt our operating results, damage our reputation, and seriously harm our business and prospects.

Our products incorporate and rely upon licensed third-party technology, and if licenses of third-party technology do not continue to be available to us or are not available on terms acceptable to us, our revenues and ability to develop and introduce new products could be adversely affected.

We integrate licensed third-party technology into certain of our products. From time to time, we may be required to renegotiate our current third party licenses or license additional technology from third-parties to develop new products or product enhancements or to facilitate new business models. Third-party licenses may not be available or continue to be available to us on commercially reasonable terms. The failure to comply with the terms of any license, including free open source software, may result in our inability to continue to use such license. Some of our agreements with our licensors may be terminated for convenience by them. In addition, we cannot be certain that our licensors are not infringing the intellectual property rights of third parties or that our licensors have sufficient rights to the licensed intellectual property in all jurisdictions in which we may sell our products. Third party technology we incorporate into our products that is deemed to infringe on the intellectual property of others may result, and in some cases has resulted, in limitations on our ability to source technology from those third parties, restrictions on our ability to sell products that incorporate the infringing technology, increased exposure to liability that we will be held responsible for incorporating the infringing technology in our products and increased costs involved in removing that technology from our products or developing substitute technology. Our inability to maintain or re-license any third-party licenses required in our products or our inability to obtain third-party licenses necessary to develop new products and product enhancements, could require us, if possible, to develop substitute technology or obtain substitute technology of lower quality or performance standards or at a greater cost, any of which could delay or prevent product shipment and harm our business, financial condition, and results of operations.

We sell our products to customers that use those products to build networks and IP infrastructure, and if the demand for network and IP systems does not continue to grow, our business, financial condition, and results of operations could be adversely affected.

A substantial portion of our business and revenues depends on the growth of secure IP infrastructure and on the deployment of our products by customers that depend on the continued growth of IP services. As a result of changes in the economy, capital spending or the building of network capacity in excess of demand, all of which have in the past particularly affected telecommunications service providers, spending on IP infrastructure can vary, which could have a material adverse effect on our business, financial condition, and results of operations. In addition, a number of our existing customers are evaluating the build-out of their next generation networks. During the decision-making period when our customers are determining the design of those networks and the selection of the software and equipment they will use in those networks, such customers may greatly reduce or suspend their spending on secure IP infrastructure. Such delays in purchases can make it more difficult to predict revenues from such customers can cause fluctuations in the level of spending by these customers and, even where our products are ultimately selected, can have a material adverse effect on our business, financial condition, and results of operations.

We are required to evaluate the effectiveness of our internal control over financial reporting and publicly disclose material weaknesses in our controls. Any adverse results from such evaluation may adversely affect investor perception, and our stock price.

Section 404 of the Sarbanes-Oxley Act of 2002 requires our management to assess the effectiveness of our internal control over financial reporting and to disclose in our filing if such controls were unable to provide assurance that a material error would be prevented or detected in a timely manner. We have an ongoing program to review the design of our internal controls framework in keeping with changes in business needs, implement necessary changes to our controls design and test the system and process controls necessary to comply with these requirements. If in the future, our internal controls over financial reporting are determined to be not effective resulting in a material weakness or significant deficiency, investor perceptions regarding the reliability of our financial statements may be adversely affected which could cause a decline in the market price of our stock and otherwise negatively affect our liquidity and financial condition.

Failure to maintain our credit ratings could adversely affect our cost of funds and related margins, liquidity, competitive position and access to capital markets.

The major credit rating agencies routinely evaluate our indebtedness. This evaluation is based on a number of factors, which include financial strength as well as transparency with rating agencies and timeliness of financial reporting. There can be no assurance that we will be able to maintain our credit ratings and failure to do so could adversely affect our cost of funds and related margins, liquidity, competitive position and access to capital markets.


We may be unable to generate the cash flow to satisfy our expenses, make anticipated capital expenditures or service our debt obligations, including the Senior Notes and the Revolving Credit Facility.

In February 2016,As of December 31, 2017, we have issued $350.0$2,150.0 million aggregate principal amount of 3.125% senior notes due 2019, which we refer to as the 2019 Notes, and $150.0 million aggregate principal amount of 4.5% senior notes due 2024, which we refer to as the 2024 Notes. In March 2015, we issued $300.0 million aggregate principal amount of 3.30% senior notes due 2020, which we refer to as the 2020 Notes, and $300.0 million aggregate principal amount of 4.35% senior notes due 2025, which we refer to as the 2025 Notes. In addition, in March 2014, we issued $350.0 million aggregate principal amount of our 2024 Notes and in March 2011, we issued $1.0 billion aggregate principal amount of senior unsecured notes, which we refer to collectively as the Senior Notes, and together with the 2019 Notes, 2020 Notes, 2024 Notes and 2025 Notes, the Noteshad $2,136.3 million in outstanding long-term debt (see discussion in Note 9,10, Debt and Financing, in the Notes to Consolidated Financial Statements of this Report). As of December 31, 2016, we had $2,133.7 million in outstanding long-term debt. In June 2014, we entered into a Credit Agreement with certain institutional lenders that provides for a five year $500.0 million unsecured revolving credit facility, which we refer to as the Revolving Credit Facility, with an option to increase the Revolving Credit Facility by up to a maximum of $700.0an additional $200.0 million. The Credit Agreement will terminate in June 2019, at which point all amounts borrowed must be repaid. As of December 31, 2016,2017, no amounts were outstanding under the Credit Agreement.

We may not be able to generate sufficient cash flow to enable us to satisfy our expenses, make anticipated capital expenditures or service our indebtedness, including the Notes and the Revolving Credit Facility (if drawn upon). Our ability to pay our expenses, satisfy our debt obligations, refinance our debt obligations and fund planned capital expenditures will depend on our future performance, which will be affected by general economic, financial, competitive, legislative, regulatory and other factors beyond our control. Based upon current levels of operations, we believe cash flow from operations and available cash will be adequate for at least the next twelve months to meet our anticipated requirements for working capital, capital expenditures and scheduled payments of principal and interest on our indebtedness, including the Notes and the Revolving Credit Facility (if drawn upon). However, if we are unable to generate sufficient cash flow from operations or to borrow sufficient funds in the future to service our debt, we may be required to sell assets, reduce capital expenditures, refinance all or a portion of our existing debt (including the Notes), repatriate off-shore cash to the U.S. at unfavorable tax rates or obtain additional financing. There is no assurance that we will be able to refinance our debt, sell assets or borrow more money on terms acceptable to us, or at all.

The indentures that govern the Notes contain various covenants that limit our ability and the ability of our subsidiaries to, among other things:

incur liens;

incur sale and leaseback transactions; and

consolidate or merge with or into, or sell substantially all of our assets to, another person.

The Credit Agreement contains two financial covenants along with customary affirmative and negative covenants that include the following:

maintenance of a leverage ratio no greater than 3.0x and an interest coverage ratio no less than 3.0x

covenants that limit or restrict the ability of the Company and its subsidiaries to, among other things, grant liens, merge or consolidate, dispose of all or substantially all of its assets, change their accounting or reporting policies, change their business and incur subsidiary indebtedness, in each case subject to customary exceptions for a credit facility of this size and type.

As a result of these covenants, we are limited in the manner in which we can conduct our business, and we may be unable to engage in favorable business activities or finance future operations or capital needs. Accordingly, these restrictions may limit our ability to successfully operate our business. A failure to comply with these restrictions could lead to an event of default, which could result in an acceleration of the indebtedness. Our future operating results may not be sufficient to enable compliance with these covenants to remedy any such default. In addition, in the event of an acceleration, we may not have or be able to obtain sufficient funds to make any accelerated payments, including those under the Notes, and the Revolving Credit Facility (if drawn upon).

In addition, certain changes under the Tax Act may result in limitations on the deductibility of our net business interest expenses. Beginning in 2018, the Tax Act generally limits the annual deduction for net business interest expense to an amount equal to 30% of adjusted taxable income. As a result, if our taxable income were to decline, we may not be able to fully deduct our net interest expense. These changes, among others under the Tax Act, could result in increases to our future U.S. tax expenses, which could have a material impact on our business.


Our failure to pay quarterly dividends to our stockholders or the failure to meet our commitments to return capital to our stockholders could have a material adverse effect on our stock price.

In January 2017, we announced a cash dividend of $0.10 per share of common stock payable on March 22, 2017 to stockholders of record as of the close of business on March 1, 2017. Our ability to pay quarterly dividends or achieve our intended capital return policy will be subject to, among other things, our financial position and results of operations, available cash and cash flow, capital and debt service requirements, use of cash for acquisitions and other factors. Any failure to pay or increase future dividends as announced, or a reduction or discontinuation of quarterly dividends could have a material adverse effect on our stock price.

We have announced that, beginning in 2017, we intend to target a capital return policy, inclusive of share repurchases and dividends, of approximately 50% of annual free cash flow. Free cash flow is calculated as net cash provided by operating activities less capital expenditures. In January 2018, we announced that our Board of Directors approved a new $2 billion buyback authorization, which replaced our prior authorization. In February 2018, as a part of our new buyback authorization, we entered into a $750 million accelerated share repurchase program. In addition, our Board of Directors declared an increase to our quarterly cash dividend to $0.18 per share, which reflects an increase of 80% compared to previous quarterly dividends. Any failure to meet our commitments to return capital to our shareholdersstockholders could have a material adverse effect on our stock price.

The investment of our cash balance and our investments in government and corporate debt securities are subject to risks, which may cause losses and affect the liquidity of these investments.

At December 31, 2016,2017, we had $1,833.2$2,006.5 million in cash and cash equivalents and $1,824.1$2,014.5 million in short- and long-term investments. We have invested these amounts primarily in asset-backed securities, certificates of deposit, commercial paper, corporate debt securities, foreign government debt securities, government- sponsored enterprise obligations, money market funds, mutual funds, publicly-traded equity securities, time deposits, U.S. government agency securities, and U.S. government securities. Certain of these investments are subject to general credit, liquidity, market, sovereign debt, and interest rate risks. Our future investment income may fall short of expectations due to changes in interest rates or if the decline in fair value of our publicly traded debt or equity investments is judged to be other-than-temporary. These market risks associated with our investment portfolio may have a material adverse effect on our liquidity, financial condition, and results of operations.

Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.

Our amended and restated bylaws provide that, unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or if the Court of Chancery does not have jurisdiction, the U.S. District Court for the District of Delaware) is the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a claim of breach of fiduciary duty owed by any of our current or former directors, officers, or other employees to us or to our stockholders; (iii) any action asserting a claim arising pursuant to the Delaware General Corporation Law, our restated certificate of incorporation, or our bylaws; (iv) any action or proceeding asserting a claim as to which Delaware General Corporation Law confers jurisdiction on the Court of Chancery or (v) any action asserting a claim governed by the internal affairs doctrine. The exclusive forum provisions in our bylaws may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our current or former directors, officers, or other employees, which may discourage such lawsuits against us and our current or former directors, officers, and other employees. Alternatively, if a court were to find the exclusive forum provisions contained in our bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could have a material and adverse impact on our business.


Uninsured losses could harm our operating results.

We self-insure against many business risks and expenses, such as intellectual property litigation and our medical benefit programs, where we believe we can adequately self-insure against the anticipated exposure and risk or where insurance is either not deemed cost-effective or is not available. We also maintain a program of insurance coverage for various types of property, casualty, and other risks. We place our insurance coverage with various carriers in numerous jurisdictions. The types and amounts of insurance that we obtain vary from time to time and from location to location, depending on availability, cost, and our decisions with respect to risk retention. The policies are subject to deductibles, policy limits, and exclusions that result in our retention of a level of risk on a self-insurance basis. In addition, our insurance coverage may not be adequate to compensate us for all losses or failures that may occur. Losses not covered by insurance could be substantial and unpredictable and could adversely affect our financial condition and results of operations.

Our stock price may be volatile.

Historically, our common stock has experienced substantial price volatility, particularly as a result of variations between our actual financial results and the published expectations of analysts and as a result of announcements by our competitors and us. Furthermore, speculation in the press or investment community about our strategic position, financial condition, results of operations, business, security of our products, or significant transactions can cause changes in our stock price. In addition, the stock market has experienced extreme price and volume fluctuations that have affected the market price of many technology companies in particular and that have often been unrelated to the operating performance of these companies. These factors, as well as general economic and political conditions and the announcement of proposed and completed acquisitions or other significant transactions, or any difficulties associated with such transactions, by us or our current or potential competitors, may materially adversely affect the market price of our common stock in the future.

ITEM 2. Properties

Our corporate headquarters are located on 80 acres of owned land in Sunnyvale, California and includes approximately 0.7 million square feet of owned buildings. In addition to our owned facilities, we lease approximately 0.2 million square feet in buildings in Sunnyvale, California as part of our corporate headquarters as of December 31, 2016.2017.

In addition to our leased officesbuildings in Sunnyvale, we also lease space (including offices and other facilities) in various locations throughout the United States, Canada, South America, EMEA, and APAC regions, including offices in Australia, China, Hong Kong, India, Ireland, Israel, Japan, the Netherlands, Russia, United Arab Emirates, and the United Kingdom. As of December 31, 2016,2017, we leased approximately 1.8 million square feet worldwide, with approximately 39 percent38% in North America. The respective operating leases expire at various times through March 2026.2028. In addition, in July 2015 we entered into a lease arrangement through March 2026 for approximately 63,000 square feet of space in the State of Washington. Each leased facility is subject to an individual lease or sublease, which could provide various options to renew/terminate the agreement or to expand/contract the leased space. We believe that our current offices and other facilities are in good condition and appropriately support our current business needs. We may improve, replace or reduce facilities as considered appropriate to meet the needs of our operations.

Stockholders
As of February 17, 2017,16, 2018, there were 846832 stockholders of record of our common stock and we believe a substantially greater number of beneficial owners who hold shares through brokers, banks or other nominees.

Dividends

In 2016 and 2015, weWe paid cash dividends of $0.10 per share each quarter, totaling $150.4 million and $152.5 million, during the years ended December 31, 2017 and $156.3 million2016, respectively. In January 2018, we declared an increase of our quarterly cash dividend to $0.18 per annum, respectively.share to be paid on March 22, 2018 to stockholders of record as of the close of business on March 1, 2018. This reflects an increase of 80% compared to previous quarterly dividends. The declaration and amount of any future cash dividends are at the discretion of the Board of Directors and will depend on our financial performance, economic outlook, and any other relevant considerations. Beginning in 2017, we currently intend to target a capital return policy, inclusive of share repurchases and dividends, of approximately 50% of annual free cash flow. Free cash flow is calculated as net cash provided by operating activities less capital expenditures.

Fiscal year 2017 includes the adoption of ASU No. 2016-09 (Topic 718) Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of the accounting for share-based payment transactions, including the accounting for forfeitures, among other things. The Company elected to account for forfeitures as they occur using a modified retrospective transition method, rather than estimating forfeitures, resulting in a cumulative-effect adjustment of $9.0 million, which increased the January 1, 2017 opening accumulated deficit balance on the Consolidated Balance Sheets.




ITEM 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read with the Consolidated Financial Statements and the related notes in Item 8 of Part II of this Report.

The following discussion is based upon our Consolidated Financial Statements included elsewhere in this Report, which have been prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP. In the course of operating our business, we routinely make decisions as to the timing of the payment of invoices, the collection of receivables, the manufacturing and shipment of products, the fulfillment of orders, the purchase of supplies, and the building of inventory and spare parts, among other matters. Each of these decisions has some impact on the financial results for any given period. In making these decisions, we consider various factors including contractual obligations, customer satisfaction, competition, internal and external financial targets and expectations, and financial planning objectives. Each of these decisions has some impact on the financial results for any given period. For further information about our critical accounting policies and estimates, see “Critical Accounting Policies and Estimates” section included in this “Management's Discussion and Analysis of Financial Condition and Results of Operations.”

To aid in understanding our operating results for the periods covered by this Report, we have provided an executive overview, andwhich includes a summary of theour business and market environment.environment along with a financial results and key performance metrics overview. These sections should be read in conjunction with the more detailed discussion and analysis of our consolidated financial condition and results of operations in this Item 7, our “Risk Factors” section included in Item 1A of Part I, and our Consolidated Financial Statements and notes thereto included in Item 8 of Part II of this Report.

Executive Overview

Business and Market Environment

Juniper Networks designs, develops, and sells products and services for high-performance networks to enable customers to build scalable, reliable, secure and cost-effective networks for their businesses, while achieving agility, efficiency and value through automation. We focus on customers and partners across our key market verticals who view these network attributes as fundamental to their business; including Telecom, Cable Providers, Cloud Providers, National Government, Financial Services, and Strategic Enterprise Verticals.

Our products are sold in three geographic regions: Americas; Europe, Middle East, and Africa, or EMEA; and Asia Pacific, or APAC. OurWe sell our high-performance network products and service offerings across routing, switching, and security networkingtechnologies. In addition to our products, we offer our customers services, including maintenance and service offerings are sold to global service providers, cloud providers, national governments, researchsupport, professional services, and public sector organizationseducation and other enterprises who view the network as critical to their success.training programs. We believe that our silicon, systems, and software represent innovations that transform the economics and experience of networking, helping our customers achieve superior performance, greater choice, and flexibility, while reducing overall total cost of ownership. In addition to our products, we offer our customers worldwide services, including technical support, professional services, and education and training programs.

Our fiscal 2016 results saw modest net revenue growth that was primarily driven by Cloud Providers, which increased more than 25% in 2016, compared to the same period in 2015. While routing revenue was slightly down, our PTX family of products had significant year-over-year growth. Switching revenue increased 12% in 2016, compared to the same period in 2015 driven by continued data center strength led by our QFX family of products, which increased more than 50% year-over-year. Our security revenues continued to decline as this component of our business is transitioning from legacy security products to our new SRX security offerings, which were introduced throughout 2016. We expect this transition in security to continue over the next few quarters. Our Services business continues to be strong with another year of solid year-over-year revenue growth, increasing 13% in 2016 compared to the same period in 2015.

In reviewing our top 10 customers for the year, four were Cloud Providers, four were Telecoms, and two were Enterprises. Of these customers, two were located outside of the U.S.

We continue to operate in a competitive market and expect the timing of our customers’ deployment patterns to vary from quarter to quarter. We intend to manage our business in 2017 with these considerations in mind and will continue to focus on driving shareholder value. We expect to adhere to the following three financial principles that provide insight into our operating plans for 2017:

We will continue to pursue opportunities for revenue growth in 2017 with our differentiated product portfolio within our target markets and will focus on growth from emerging technologies as the market landscape continues to evolve.

We remain focused on earnings expansion with long-term consistency. We will remain diligent in managing our operating expenses while also investing in our product portfolio for the short and long-term.


We intend to maintain a healthy balance sheet and an optimized capital structure, while balancing internal investments and the potential for value-enhancing M&A. We expect continued strong cash flow generation and intend to return approximately 50% of free cash flow to shareholders. Free cash flow is calculated as net cash provided by operating activities less capital expenditures.

We are focused on operational excellence, cost discipline and targeted growth initiatives, as well as partnerships and expect to continue to evaluate strategic acquisitions. In 2016, we completed three acquisitions that we expect will further enhance our product portfolio and that we believe will allow us to accelerate our strategy to transition to cloud-based markets. In April 2016, we acquired optical equipment provider BTI Systems Inc., or BTI, which we expect will accelerate our ability to address the data center interconnect, or DCI, and metro Ethernet markets with open, programmable and automated, packet optical transport solutions. Then in August 2016, we acquired Aurrion, Inc., or Aurrion, a provider of fabless silicon photonic technology, which we expect will strengthen our long-term competitive advantage in cost-effective, high-density, high-speed optical networks. Lastly, in December 2016 we acquired AppFormix, a company focused on cloud infrastructure optimization software, which we expect will complement the analytics and capabilities of Contrail and help customers enhance their cloud operations. We expect that we will continue to look at targeted and strategic acquisitions that we believe can complement our product portfolio, operations or R&D strategy.

Further, our intent is to lead in the area of software solutions that simplify the operation of networks, and to allow our customers across our key verticals to deliver realfurther value over thosetheir networks. We anticipate that our increased focus on software business models will result in an increase in software revenue as a percentage of total revenue over time.

In 2016,2017, we began reporting revenue on the following verticals: Cloud, Telecom/Cable, and Strategic Enterprise, which we believe better aligns with our business model compared to our previous reporting of revenue by Service Provider and Enterprise. A summary of the types of customers included in our verticals is as follows:

Cloud: companies that are heavily reliant on the cloud for their business model’s success. As an example, customers in the cloud vertical can include cloud service providers as well as enterprises that provide software-as-a-service, infrastructure-as-a-service, or platform-as-a-service.

Telecom/Cable: includes wireline and wireless carriers and cable operators.

Strategic Enterprise: includes enterprises not included in the Cloud vertical. In particular, they are industries with high performance, high agility requirements, including financial services; national, federal, state, and local governments; as well as research and educational institutions.

We are focused on and continue to see significant opportunities from the implementation of cloud architectures, such as large public and private data centers, as well as distributed cloud infrastructure which resides in multiple, distributed data centers in order to place applications or services closer to end users, such as enabling security and networking as a service.


We believe the network needs for our customers in our Telecom/Cable and Cloud verticals are converging, as are those of Strategic Enterprises, as all of these customers recognize the need for high performance networks and leveraging the cloud for improved agility and greater levels of operating efficiency.

As these customers continue to grow, we believe their network architectures will continue to evolve. We believe our understanding of high performance networking technology, and our strategy, position us to capitalize on the industry transition to more automated, cost-efficient, scalable networks.

In routing, we believe that certain large cloud customers are starting to transition their wide area networks from scale-up to a scale-out architecture as they continue to add capacity, which has resulted and we expect may continue to result in a transition of these customers from purchasing our MX product family to our PTX product family. These architectural shifts have led to a near-term slowdown in our net revenues as in some cases there is a pause before the new architecture ramps as well as lower average selling prices for PTX product family compared to MX product family. We are unable to predict the exact timing or duration of the transition, as it will vary from customer to customer.

In switching, we see that certain large cloud customers who can rapidly scale based on increased demand are in the process of adopting 100-Gigabit connections, or 100G, resulting in certain large deployment delays at our largest cloud customers as they prepare for this adoption. 

Despite these ongoing deployment delays and architectural shifts, we remain confident in our competitive position and strong relationships with these strategic customers. Our overall strategy with our cloud customers has not changed and we continue to execute against our innovation roadmap, which includes our plan to continue to grow our relevance and our business in the cloud vertical.

In 2017, we continued to execute on our product strategy, specifically around the cloud. We announced Cloud-Grade Networking, which we expect will accelerate agility and innovation with cloud customers. Cloud-Grade Networking builds on carrier-grade reach and reliability with enterprise-grade control and usability, bringing cloud-level agility and operational scale to networks everywhere. This announcement included two new foundational products:
Junos Node Slicing: converges multiple concurrent network functions on the same physical routing infrastructure, letting customers optimize their infrastructure while offering differentiated services with enhanced operational and administrative isolation within a single chassis.
Universal Chassis: a breakthrough system allowing customers to standardize on a hardware platform across their data center, core, and network edge. We believe the system will create significant advancements in performance and automation across a number of key solution areas andvalue for our customers by enhancing their return on investment through reduced costs.
Aligning with our Cloud-Grade Networking initiative, we also announced a numberProgrammable Photonic Layer solution, comprised of new productstwo main products: TCX1000 Series Programmable ROADM and proNX Optical Director. This solution is a disaggregated optical line system that is designed to offer greater levels of flexibility, cost control, and multi-layer visibility to packet-optical transport.
We also announced enhancements to our hardware and software products across routing, switching, and security.

In routing, our solution for wide area IP transport across Data Center Interconnect, Metro, and Core was enhanced with the introduction of our newest PTX line-cards, coupled with our multi-layer optimization controller, NorthStar.           

In switching, we announced two new access switches, the EX2300 and EX3400 in 2016. Further, we introduced Juniper Networks Cloud-Enabled Branch, a solution that will allow enterprises and managed service providers alike to create and automate delivery of branch office networking services on-demand.

In security, we announced Juniper Networks cSRX, a next-generation containerized firewall providing advanced security services for Software-Defined Secure Networks, or SDSN, as well asplatform and expanded our public cloud offering with the introduction of vSRX for Microsoft Azure. Our SDSN enhancements deliver pervasive security across multi-vendor environments, public clouds, and private clouds. Further, we announced enhancements to our Contrail Cloud platform that includes AppFormix integrations, pre-validated virtual network functions, and a multi-core versionmanaged solution of the Juniper Networks vSRX.professional services offering to simplify our customers' transition to telco clouds.
In addition, we announced further cloud-based enhancements to our security portfolio. We introduced our Contrail Security product, a new solution specifically designed to allow enterprises and Software-as-a-Service, or SaaS, cloud providers to protect applications running in multiple cloud environments. We also announced Junos Space Security Director, Policy Enforcer, new SRX4100 and SRX4200 firewalls, and new enhancementscompleted the acquisition of Cyphort Inc., a software company that provides security analytics for advanced threat defense. This acquisition is expected to strengthen the capabilities of our cloud-based threat prevention service, Sky Advanced Threat Prevention, or Sky ATP, by increasing efficiency and performance and providing additional threat detection functionalities and analytics. We will continue to further build outlook at targeted and strategic acquisitions that we believe can complement our SDSN platform.product portfolio, operations, R&D strategy or overall business.

We also expanded our global alliances with NEC to deliver NFV-based solutions that allow service providers and enterprises to gain greater service agility through automation.

We believe we are entering 2017 with a competitive product portfolio and a determination to enable our customers' cloud businesses, or to successfully migrate to cloud architectures. The cloud transformation is our primary area of strategic focus as we see significant opportunities arising from the shift towards the cloud and network automation. We believe our history as an innovation leader and our understanding of high performance networking technology position us to capitalize on this industry transition.

DSO and product book-to-bill areis for the fourth quarter ended December 31, 2017, 2016, 2015, and 2014.2015.

Net Revenues: During 2016,2017, net revenues increased compared to 2015,2016, due to growth from our services business driven by strong growth in services revenuesattach rates and renewals of support contracts, partially offset by a slight decline in product revenue.revenues. The decline in product revenuerevenues was primarily driven by a decline inlower revenues from our MXrouting products as well asa result of the continued architectural shifts in the Cloud vertical to more automated, cost efficient, and scalable networks and a decrease in our high-end SRX series in our security products. In addition, we saw continued competitive pricing pressures,business. This was partially offset by revenuean increase in net revenues from our switching products driven by continued growth from our new products, specifically in switching where we saw continued data center strength.switching portfolio, particularly from our QFX product family which grew 25% year-over-year.

Of our top ten customers for 2017, four were Cloud, five were Telecom/Cable, and one was a Strategic Enterprise. Of these customers, two were located outside of the U.S.

Gross Margin: Our gross margin as a percentage of net revenues decreased during 2016,2017, compared to 2015,2016, primarily due to elevated pricing pressures,lower product net revenues, customer mix, and product mix and charges related toresulting from the expected remediation costs for certain products containingyear-over-year decline in routing revenues, including as a defect in a clock-signal component from a third-party supplier,result of architectural shifts described above, partially offset by an improvement in services margin and our supply chain cost structure. We expect that we will continue to experience elevated pricing pressures in the near term.higher service gross margin.

Operating income (loss):Margin: During 2016,2017, compared to 2015,2016, operating income as a percentage of net revenues decreased as a result of higher operating expense primarily due to acquisitions completed in 2016 as well as a decline inlower gross margin as a percentage of net revenue,discussed above and higher operating expenses primarily from restructuring charges, partially offset by savings in variable compensationhigher net revenues driven by the strength from our services and improvements to our supply chain cost structure.switching businesses.

Capital Return: During 2016, we completed our full commitment to return $4.1 billion of capital, inclusive of share repurchases and dividends, to shareholders from 2014 through the end of 2016. During 2016, In 2017, we repurchased 13.526.1 million shares of our common stock for an aggregate purchaseamount of $312.9$719.7 million and paid cash dividends of $0.10 per share each quarter for an aggregate annual amount of $152.5$150.4 million. Beginning in 2017, we intend to target a capital return policy of approximately 50% of annual free cash flow, inclusive of share repurchases and dividends.

Operating Cash Flows: Cash flow from operations increased by $213.5 million in 2016,2017, compared to 2015,2016, primarily driven by timing differencesdue to an increase in working capital.cash collections from customers in the first half of 2017 due to higher invoicing activity during the fourth quarter

of 2016, partially offset by an increase in payments to suppliers, higher payments for restructuring activities, and an increase in cash paid for income taxes.

DSO: DSO is calculated as the ratio of ending accounts receivable, net of allowances, divided by average daily net salesrevenues for the preceding 90 days. DSO for the quarter ended December 31, 2016 increased by 15 days, or 28%2017 decreased, compared to the quarter ended December 31, 2015. The elevated DSO was2016, primarily due to a significant increase inlower invoicing of services which occurred late in 2016 and resulted in higher deferred services revenue, as well as the timing of product invoicing. We believe the quality of our receivables is strong as the majority has been received early in the first quarter of 2017. Going forward we expect DSO to be in the 50 to 60 days range.activities.

Product Book-to-Bill: Product book-to-bill represents the ratio of product orders booked divided by product revenues during the respective period. Product book-to-bill was greater than one for the quarters ended December 31, 2016, 2015 and 2014, which we believe indicates positive product demand.

Deferred Revenue: Total Product deferred revenue increased by $313.0 million to $1,481.1 million as of December 31, 2016,2017, compared to $1,168.1 million as of December 31, 2015,2016, primarily due to (1) an increase in deferred service revenue of $230.4 million driven by an increase in multi-year support agreements, which are billed in advance, and (2) an increase in product deferred revenue primarily due to higher deferrals related to software revenue arrangements, which are recognized ratably over the agreement, and other shipments that have not met allcertain revenue recognition criteria. In circumstances when costs are deferred, deferred product revenue is recorded net of the related costs of product revenue.

In February 2017, we completed our evaluation of the impact of a defect in a clock-signal component contained in certain of our products which may begin to fail after the product has been in operation for 18 months as advised by the third party component supplier. As a result, we recorded a product cost of revenue charge of approximately $10.8 million in other accrued liabilities on the Consolidated Balance Sheet as of December 31, 2016 for the expected remediation costs of the component defect. We are in the process of working with our customers and the component supplier to implement a remediation.

Critical Accounting Policies and Estimates

The preparation of the financial statements and related disclosures in conformity with U.S. GAAP requires us to make judgments, assumptions, and estimates that affect the amounts reported in the Consolidated Financial Statements and the accompanying notes. On an ongoing basis, we evaluate our estimates, including those related to sales returns, pricing credits, warranty costs, allowance for doubtful accounts, impairment of long-term assets, especially goodwill and intangible assets, contract manufacturer exposures for carrying and obsolete material charges,liabilities, assumptions used in the valuation of share-based compensation, and litigation. We base our estimates and assumptions on current facts, historical experience, and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. For further information about our significant accounting policies, see Note 2, Significant Accounting Policies, in Notes to Consolidated Financial Statements in Item 8 of Part II of this Report, which describes the significant accounting policies and methods used in the preparation of the Consolidated Financial Statements. The accounting policies described below are significantly affected by critical accounting estimates. Such accounting policies require significant judgments, assumptions, and estimates used in the preparation of the Consolidated Financial Statements and actual results could differ materially from the amounts reported based on these policies. To the extent there are material differences between our estimates and the actual results, our future consolidated results of operations may be affected.

Goodwill.
Goodwill: We make significant estimates, assumptions, and judgments when valuing goodwill and other intangible assets in connection with the initial purchase price allocation of an acquired entity, as well as when evaluating impairment of goodwill and other intangible assets on an ongoing basis. These estimates are based upon a number of factors, including historical experience, market conditions, and information obtained from the management of the acquired company. Critical estimates in valuing certain intangible assets include, but are not limited to, historical and projected customer retention rates, anticipated growth in revenue from the acquired customer and product base, and the expected use of the acquired assets. These factors are also considered in determining the useful life of the acquired intangible assets. The amounts and useful lives assigned to identified intangible assets impacts the amount and timing of future amortization expense.

Goodwill represents the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recorded. The excess of the purchase price over the estimated fair value of net assets of businesses acquired in a business combination is recognized as goodwill. We evaluate our goodwill for impairment on an annual basis, as of November 1st, or more frequently if an event occurs or facts and circumstances change that would more likely than not reduce the fair value of our reporting units below their carrying amount.

Goodwill is tested for impairment at the reporting unit level, which is one level below our operating segment level, by comparing the reporting unit's carrying value, including goodwill, to the fair value of the reporting unit. The reporting units are determined based on the components of our operating segment that constitutes a business for which discrete financial information is available and segment management regularly review the operating results of the component.

The provisions of the accounting standard for goodwill and other intangibles allows us to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Various factors are considered in the qualitative assessment, including macroeconomic conditions, financial performance, or a sustained decrease in share price. If as a result of the qualitative assessment, it is deemed more likely than not that the fair value of a reporting unit is less than its carrying amount, management will perform the quantitative test.

The quantitative goodwill impairment test, if necessary, involves a two-step process to identify goodwill impairment and measure the amount of goodwill impairment loss to be recognized, if any. The first step tests for potential impairment by comparing the fair value of reporting units with the reporting unit’s net assetcarrying values. If the fair value of the reporting units exceeds the carrying value of the reporting unit’s net assets, goodwill is not impaired and no further testing is required. If the fair value of the reporting units does not exceed the carrying value of the net assets assigned to the

reporting unit, then we perform the second step of the impairment test in order to determine the implied fair value of the reporting unit's goodwill. The second step requires an assignment of the reporting unit’s fair value to the reporting unit’s assets and liabilities, using the relevant acquisition accounting guidance, to determine the implied fair value of the reporting unit’s goodwill. The implied fair value of the reporting unit’s goodwill is then compared with the carrying amount of the reporting unit’s goodwill, and if the carrying value of a reporting unit's goodwill exceeds its implied fair value, we record an impairment loss equal to the difference.

In the first step, the fair value of each of our reporting units is determined using both the income and market valuation approaches. We believe the income approach and the market approach are equally representative of the reporting unit’s fair value. Under the income approach, the fair value of the reporting unit is based on the present value of estimated future cash flows that the reporting unit is expected to generate over its remaining life. Under the market approach, the value of the reporting unit is based on an analysis that compares the value of the reporting unit to values of publicly-traded companies in similar lines of business. In the application of the income and market valuation approaches, we are required to make estimates of future operating trends and judgments on discount rates and other variables. Determining the fair value of a reporting unit is highly judgmental in nature and involves the use of significant estimates and assumptions. We base our fair value estimates on assumptions we believe to be reasonable, but that are unpredictable and inherently uncertain. Actual future results related to assumed variables could differ from these estimates. In addition, we make certain judgments and assumptions in allocating shared assets and liabilities to determine the carrying values for each of our reporting units.

Under the income approach, we calculate the fair value of a reporting unit based on the present value of estimated future cash flows. Cash flow projections are based on management's estimates of revenue growth rates and operating margins, taking into consideration industry and market conditions. The discount rate used is based on the weighted-average cost of capital adjusted for the relevant risk associated with business-specific characteristics and the uncertainty related to the business's ability to execute on the projected cash flows. Under the market approach, we estimate the fair value based on market multiples of earnings derived from comparable publicly-traded companies with similar operating and investment characteristics as the reporting units, and then apply a control premium which is determined by considering control premiums offered as part of the acquisitions that have occurred in market segments that are comparable with our reporting units. The income approach and the market approach are equally weighted to derive the fair value of the reporting unit.

In the second step, the reporting unit's fair value is allocated to all of the assets and liabilities, including any unrecognized intangible assets; such as, existing technology, backlog, and customer relationships, in a hypothetical analysis that calculates the implied fair value of goodwill in the same manner as if the reporting unit was being acquired in a business combination. If the implied fair value of the reporting unit's goodwill is less than the carrying value, the difference is recorded as an impairment loss. Assumptions used in measuring the fair value of these assets and liabilities included the discount rates, customer renewal rates, and technology obsolescence rates used in valuing intangible assets, and pricing of comparable transactions in the market in valuing the tangible assets.

During the second quarter of 2017, we concluded that there were sufficient indicators to require us to perform an interim goodwill impairment analysis on our Security reporting unit. Based on our analysis, we determined that our Security reporting unit’s goodwill was not impaired.

During the fourth quarter of 2016,2017, we performed a quantitativequalitative assessment for all of our reporting units: Routing, Switching, and Security. This quantitativequalitative assessment included the review of certain macroeconomic factors and entity-specific qualitative factors to determine if it was performed by determining the fair value of each reporting unit using a combination of the income approach and the market approach. Based on the outcome of the quantitative assessments, we determinedmore-likely-than-not that the fair values of eachour reporting unit significantly exceeded its respectiveunits were below carrying value, resultingvalue. We considered macroeconomic factors including the economic growth, general macroeconomic trends and growth for the markets in nowhich the reporting units operate, changes in the industry environment, and the performance of market competitors. In addition to these macroeconomic factors, we considered the reporting units’ current results and forecasts, any changes in the nature of the business, any changes in cost factors, any significant legal, regulatory, contractual, or other business factors, and changes in the carrying values. As a result of our qualitative assessment, we concluded that it was more-likely-than-not that our goodwill impairment.was not impaired and we did not perform a quantitative assessment.

Inventory Valuation and Contract Manufacturer Liabilities.Liabilities: Inventory consists primarily of component parts to be used in the manufacturing process and finished goods in-transit, and is stated at lower of cost or market.net realizable value. A provision is recorded when inventory is determined to be in excess of anticipated demand or obsolete, to adjust inventory to its estimated realizable value. In determining the provision, we also consider estimated recovery rates based on the nature of the inventory. As of December 31, 20162017 and December 31, 2015,2016, our net inventory balances were $97.8 million and $95.5 million, and $75.0 million, respectively.

We establish a liability for non-cancelable, non-returnable purchase commitments with our contract manufacturers for quantities in excess of our demand forecasts or obsolete materials charges for components purchased by the contract manufacturers based on our demand forecasts or customer orders. We also take estimated recoveries of aged inventory into consideration when determining the liability. As of December 31, 20162017 and December 31, 2015,2016, our contract manufacturer liabilities were $14.0$22.0 million and $18.0$14.0 million, respectively.

Significant judgment is used in establishing our forecasts of future demand, recovery rates based on the nature and age of inventory, and obsolete material exposures. We perform a detailed analysis and review of data used in establishing our demand forecasts. If the actual component usage and product demand are significantly lower than forecast, which may be caused by factors within and outside of our control, or if there were a higher incidence of inventory obsolescence because of rapidly changing technology and our customer requirements, we may be required to increase our inventory write-downs and contract manufacturer liabilities, which could have an adverse impact on our gross margins and profitability. We regularly evaluate our exposure for inventory write-downs and adequacy of our contract manufacturer liabilities. Inventory and supply chain management remains an area of focus as we balance the risk of material obsolescence and supply chain flexibility in order to reduce lead times.

Revenue recognition.Recognition: Revenue is recognized when all of the following criteria have been met: (1) persuasive evidence of an arrangement exists, (2) delivery has occurred, (3) sales price is fixed or determinable, and (4) collectability is reasonably assured. We enter into contracts to sell our products and services, and while some of our sales agreements contain standard terms and conditions, there are agreements that contain multiple elements or non-standard terms and conditions. As a result, significant contract interpretation may be required to determine the appropriate accounting, including whether the deliverables specified in a multiple element arrangement should be treated as separate units of accounting for revenue recognition purposes, and, if so, how the price should be allocated among the elements and when to recognize revenue for each element. Changes in the allocation of the sales price between elements may impact the timing of revenue recognition but will not change the total revenue recognized on the contract.

Under our revenue recognition policies, we allocate revenue to each element based on a selling price hierarchy. The selling price for a deliverable is based on our vendor-specific objective evidence, or VSOE, if available, third-party evidence, or TPE, if VSOE is not available, or estimated selling price, or ESP, if neither VSOE nor TPE is available. We establish VSOE of selling price using the price charged for a deliverable when sold separately. TPE of selling price is established by evaluating largely interchangeable competitor products or services in stand-alone sales to similarly situated customers. We do not use TPE as we do not consider our products to be similar or interchangeable to our competitors' products in standalone sales to similarly situated customers. ESP is established considering internal factors such as margin objectives, pricing practices and controls, customer segment pricing strategies and product life cycle. Consideration is also given to market conditions such as industry pricing strategies and technology life cycles. When determining ESP, we apply management judgment to establish margin objectives and pricing strategies and to evaluate market conditions and product life cycles. Revenue from maintenance service contracts is deferred and recognized ratably over the contractual support period, which is generally one to three years.

Income Taxes.Taxes: We are subject to income taxes in the United States and numerous foreign jurisdictions. Significant judgment is required in evaluating our uncertain tax positions and determining our taxes. Although we believe our reserves are reasonable, no assurance can be given that the final tax outcome of these matters will not be different from that which is reflected in our historical income tax provisions and accruals. We adjust these reserves in light of changing facts and circumstances, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made.

We have accounted for the tax effects of the Tax Cuts and Jobs Act, which we refer to as the Tax Act, enacted on December 22, 2017, on a provisional basis. Our accounting for certain income tax effects is incomplete, but we have determined reasonable estimates for those effects. Our reasonable estimates are included in our financial statements

as of December 31, 2017. We expect to complete our accounting during the one year measurement period from the enactment date.

Significant judgment is also required in determining any valuation allowance recorded against deferred tax assets. In assessing the need for a valuation allowance, we consider all available evidence, including past operating results, estimates of future taxable income, and the feasibility of tax planning strategies. In the event that we change our determination as to the amount of deferred tax assets that can be realized, we will adjust our valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.

Our provision for income taxes is subject to volatility and could be adversely affected by earnings being lower than anticipated in countries that have lower tax rates and higher than anticipated in countries that have higher tax rates; by changes in the valuation of our deferred tax assets and liabilities; by expiration of or lapses in the R&D tax credit laws; by transfer pricing adjustments, including the effect of acquisitions on our intercompany R&D cost-sharing arrangement and legal structure; by tax effects of nondeductible compensation; by tax costs related to intercompany realignments; by changes in accounting principles; or by changes in tax laws and regulations, including possible U.S. changes to the taxation of earnings of our foreign subsidiaries, the deductibility of expenses attributable to foreign income, or the foreign tax credit rules. In addition, the OECD’s recommended changes to numerous long-standing tax principles, as adopted by countries, will increase tax uncertainty and may adversely affect our provision for income taxes. Significant judgment is required to determine the recognition and measurement attributes prescribed in the accounting guidance for uncertainty in income taxes. The accounting guidance for uncertainty in income taxes applies to all income tax positions, including the potential recovery of previously paid taxes, which if settled unfavorably could adversely affect our provision for income taxes or additional paid-in capital. In addition, we are subject to the continuous examination of our income tax returns by the IRS and other tax authorities. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. There can be no assurance that the outcomes from these continuous examinations will not have an adverse effect on our operating results and financial condition.

Loss Contingencies.Contingencies: We use significant judgment and assumptions to estimate the likelihood of loss or impairment of an asset, or the incurrence of a liability, in determining loss contingencies. An estimated loss contingency is accrued when it is probable that an asset has been impaired or a liability has been incurred and the amount of loss can be reasonably estimated. We record a charge equal to the minimum estimated liability for litigation costs or a loss contingency only when both of the following conditions are met: (i) information available prior to issuance of our consolidated financial statements indicates that it is probable that an asset had been impaired or a liability had been incurred at the date of the financial statements and (ii) the range of loss can be reasonably estimated. We regularly evaluate current information available to us to determine whether such accruals should be adjusted and whether new accruals are required.

Results of Operations

We sell our high-performance networking products and service offerings across routing, switching, and security to two primary markets: Service Provider and Enterprise. Our determination of the market to which a particular revenue transaction relates is based primarily upon the customer's industrial classification code, but may also include subjective factors such as the intended use of the product. The Service Provider market generally includes wireline and wireless carriers, and cable operators, as well as major Internet content and application providers. The Enterprise market is generally comprised of federal, state, and local governments; research and education institutions; financial services and other businesses.

2017 Compared to 2016

Product net revenues decreased in 2017, compared to 2016, primarily due to a decrease in routing and, to a lesser extent, security, partially offset by growth in switching.

Lower routing revenues was driven by Cloud customers in the Americas as a result of the ongoing architectural shifts in the Cloud vertical to more automated, cost efficient, and scalable networks. Routing revenues in EMEA also declined year-over-year due to lower sales from Telecom/Cable customers, partially offset by revenue growth in APAC from our Telecom/Cable vertical. As we continue to expand our footprint with certain strategic APAC Telecom and Cloud customers, particularly in Australia, we expect these strategic opportunities will ultimately help to drive revenue growth in APAC. Revenues from our MX and legacy routing products declined year-over-year, which was partially offset by an increase in revenues from our PTX products from the continued adoption of our PTX1000 series of products. We are expecting a year-over-year revenue decline in our routing business in 2018 as a result of the ongoing architectural shifts in the Cloud vertical.

Security net revenues declined in 2017, compared to 2016, primarily driven by a decrease in our high-end SRX series as it has been undergoing a product refresh cycle and the decline in our Other Legacy products. We are expecting a year-over-year revenue increase in our security business in 2018 as a result of product refresh.


The decline in product net revenues was partially offset by an increase in switching net revenues due to continued growth from our data center switching portfolio, particularly from our QFX product family, which grew 25% year-over-year. This growth was across public and private clouds driven in part by 100G adoption. The switching net revenue growth was primarily driven by the Cloud vertical in the Americas and, to a lesser extent, our Strategic Enterprise vertical. We expect that our data center switching portfolio will continue to drive revenue growth in our switching business and we expect year-over-year revenue growth in our switching business in 2018.

Service net revenues increased during in 2017, compared to 2016, primarily due to strong renewal and attach rates of support contracts. Additionally, we saw strong year-over-year services revenue growth in APAC and EMEA.

2016 Compared to 2015

Product net revenues decreased slightly in 2016, compared to 2015, primarily due to a decrease in security and, to a lesser extent, routing, partially offset by growth in switching.
The decrease in security was driven by our SRX products, which has been undergoing a product refresh cycle, and the continued decline of our Screen OS and Other Legacy products. We continue to expect that our Screen OS and Other Legacy products will not contribute to meaningful Security product revenue growth and should continue to decline over time. The decrease in security net revenues was driven by our Strategic Enterprise vertical due to competitive pressures.
Routing product net revenues decreased slightly in 2016, compared to the same period in 2015, primarily due to a decline in revenues from our MX products, resulting from lower demandsales from Telecomour Telecom/Cable vertical in the Americas and EMEA, which is impacted by the timing of large deployments. Net revenuesRevenues from our legacy T series products continued to decline, as expected, as we continuecontinued to transition to our next-generation PTX series of products. These declines were significantly offset by a strong increase in revenues from our PTX series of products due to higher sales to Cloud Providers and Telecom,Telecom/Cable customers, as well as the ramp up of sales of our new products, which we expect to continue over the next few quarters.products.
SwitchingThe decline in product net revenues increasedwas partially offset by an increase in 2016, comparedswitching, primarily due to the same period in 2015, as a result of continued growth from our data center switching portfolio, driven by higher net revenuesparticularly from our QFX product family, which increased over 50% year-over-year driven by the ramp up of sales of our new product offerings, as well as an increase in revenuerevenues from Cloud Providers.customers in Americas. This was partially offset by lower demand for our EX products, as we transitiontransitioned to our new EX product portfolio. We are focused on the growing cloud and data center market, and expect our expanded data center switching portfolio will continue to drive revenue growth in our switching business in the foreseeable future.
Security productService net revenues decreasedincreased in 2016, compared to the same period in 2015, primarily due to lower net revenues from our SRX products, which have been undergoing a product refresh cycle, as well as the continued decline of our Screen OS and Other Legacy products. We continue to expect that our Screen OS and Other Legacy products will not contribute to meaningful Security product revenue growth and should continue to decline over time. We are continuing to introduce newer SRX products, and expect this transition to continue over the next few quarters.
The increase in service net revenues in 2016, compared to the same period in 2015 was primarily driven by strong attach rates and renewals of support contracts.

2015 Compared to 2014

Routing product net revenues increased in 2015, compared to 2014, as a result of an increase from Cloud Providers, Cable, and Telecom in EMEA and APAC. During 2015, we saw a strong increase in demand from both service provider and enterprise markets for our routing products, as well as an overall increase in net revenues from our MX960, MX2020, and PTX series products.

Switching product net revenues increased in 2015, compared to 2014, primarily due to data center build-outs with Telecom and Cloud Providers. This result was enabled by the significant growth with our QFX product family. Additionally, we saw switching net revenues growth in the Americas and APAC, which was slightly offset by a decrease in EMEA. We also saw a year-over-year increase in the service provider market for our switching products.

Security product net revenues decreased in 2015, compared to 2014, primarily due to the divestiture of our Junos Pulse product lines and a continuing decline in our ScreenOS products, which was partially offset by an increase in sales of our SRX platform

and security software year-over-year. Additionally, we also saw a decrease in security net revenues within the enterprise market, which was partially offset by a slight increase in the service provider market.

The increase in service net revenues in 2015, compared to 2014, was primarily driven by new service contracts and strong contract renewals. Service revenues are largely correlated with product revenues, therefore if product net revenues decline, it can have an impact on future service revenues.

2016 Compared to 2015

Net revenues in the Americas increased in 2016, compared to the same period in 2015, primarily driven by strong growth from Cloud Providers, which increased almost 30% year-year-over, as they build out data center environments, as well as a strong increase in service revenues. This was partially offset by lower revenues from Cable Providers, due to lower demand for our MX products. In the Americas, we continue to see opportunities for us to diversify our revenue as Cloud Provider customers continue to invest in data center networks and network automation.

Net revenues in EMEA decreased in 2016, compared to the same period in 2015, primarily due to a decrease in revenues from our Strategic Enterprise vertical and the timing of deployments of large Telecoms, partially offset by growth from Cloud Providers. To a lesser extent, certain macroeconomic uncertainties in the region and elevated pricing pressures also contributed to the decline in net revenues.

Net revenues in APAC increased in 2016, compared to the same period in 2015. The increase was driven by Cloud Providers, partially offset by Telecom. Geographically, revenue growth was primarily driven by an increase in revenues from China and Japan, which was partially offset by a decline in revenues from Australia.

2015 Compared to 2014

Net revenues in the Americas increased in 2015, compared to 2014, primarily due to a strong increase in net revenues from both the service provider and enterprise markets. The increase in both the Service Provider and Enterprise markets within the Americas was due to an increase in net revenues across routing, switching, and SRX product net revenues, as well as service net revenues. In addition, we saw a strong increase in net revenues from Cloud Providers, Cable, and Enterprise, partially offset by Telecom.

Net revenues in EMEA increased in 2015, compared to 2014, primarily due to an increase in net revenues from Telecom and Cloud Providers slightly offset by a decrease in the enterprise market.

Net revenues in APAC increased in 2015, compared to 2014, primarily due to an increase in net revenues from Telecom and Cloud Providers. We experienced a significant decline in China, which was partially offset by an increase in net revenues in Japan and Australia.

2016 Compared to 2015

Net revenues from the Service Provider market increased in 2016, compared to 2015, driven by strong growth in the Americas and to a lesser extent, growth in APAC, partially offset by EMEA. Services and switching growth was partially offset by a decline in security.

Net revenues from the Enterprise market slightly decreased in 2016, compared to 2015, primarily due to a decline in revenues from security, partially offset by growth in service revenue. Net revenue declines from the Enterprise market in EMEA and APAC were partially offset by growth in the Americas.

2015 Compared to 2014

Net revenues from the service provider market increased in 2015, compared to 2014, with growth from Cloud Providers, Telecom in EMEA and APAC, and Cable. Within the service provider market, we saw strength across routing, switching, and security, with the largest increase in net revenues from routing revenue.

Net revenues from the enterprise market increased in 2015, compared to 2014, primarily due to strength in service and routing, and to a lesser extent, switching, which was partially offset by a slight decrease in revenue from our security products. Net revenues in the Americas from the enterprise market increased across routing, switching, and SRX security.

Customer

No customer accounted for greater than 10% of our net revenues during the years ended December 31, 2017, 2016, 2015, and 2014.2015.

Our gross margins as a percentage of net revenues have been and will continue to be affected by a variety of factors, including the mix and average selling prices of our products and services, new product introductions and enhancements, manufacturing and component costs, expenses for inventory obsolescence and warranty obligations, cost of support and service personnel, customer

mix as we continue to expand our footprint with certain strategic customers and certain geographic regions, and the mix of distribution channels through which our products and services are sold.

2017 Compared to 2016

Product gross margin

Product gross margin as a percentage of product revenues decreased in 2017, compared to 2016, primarily due to lower product net revenues, customer mix, and product mix resulting from the year-over-year decline in routing revenues and our customers' architectural shifts, partially offset by improvements in our cost structure. In the near-term, we expect product gross margin will continue to be affected by lower revenues and product mix, including from our customers' architectural shifts. We are undertaking specific efforts to address certain factors impacting our product gross margin. These efforts include cost reductions, performance and quality improvements through engineering to increase value across our products; optimizing our supply chain; pricing management; and increasing software and solution sales; however, there can be no guarantee that these efforts will be successful or that they will be realized in the time frame we anticipate.

We expect that our product gross margin will continue to vary in the future due to the mix of products sold, geographic mix, and competitive pricing pressures.

Service gross margin

Service gross margin as a percentage of service net revenues increased in 2017, compared to 2016, due to higher service revenues, partially offset by higher material and higher delivery costs.

2016 Compared to 2015

Product gross margin

Product gross margin decreased as a percentage of product net revenues in 2016, compared to 2015, primarily due to elevated pricing pressures, product mix, and expected remediation costs of $10.8 million for certain products containing a defect in a clock-signal component from a third-party supplier, partially offset by improvements in our cost structure. We expect that our product gross margin will continue to vary in the future due to the mix of products sold and competitive pricing pressures. We believe product

Service gross margins as a percentage of net revenues will improve in the long-term from the continued expected acceptance of our new products and technologies, the expected increase in software revenues as a percentage of total revenues as we transition to software-based business models, and as we continue to manage costs within our supply chain.margin

Service gross margin as a percentage of service net revenues increased in 2016, compared to 2015. Service gross margin increased year-over-year2015, due to an increase in support revenue as well as improvements in labor productivity and logistics, partially offset by increased support costs related to the ramp up of new products.

2015 Compared to 2014

Product gross margin increased as a percentage of product net revenues in 2015, compared to 2014, primarily due to a decrease in product cost of revenues. The decrease in cost of revenues is attributable to the non-recurrence of restructuring charges recorded in 2014 for asset write-downs. No such charges were incurred in 2015. Excluding these components from prior year cost of sales, year-over-year gross margin would remain relatively consistent.

Service gross margin as a percentage of service net revenues increased in 2015, compared to 2014. Services delivery costs increased at a slower rate than service revenue as a result of better labor efficiency and improved product quality.

Our operating expenses have historically been driven in large part by personnel-related costs, including wages,salaries and wages; commissions and bonuses, benefits,which we refer to collectively as variable compensation; benefits; share-based compensation,compensation; and travel. Facility and information technology, or IT, departmental costs are allocated to each department based on usage and headcount. We had a total of 9,381, 9,832, 9,058, and 8,8069,058 employees as of December 31, 2017, 2016, and 2015, respectively. Our headcount decreased by 451 employees, or 5%, in 2017, compared to 2016, primarily due to our restructuring plan initiated in the first quarter of 2017 to realign our workforce and 2014, respectively.increase operational efficiency, which we refer to as the 2017 Restructuring Plan. Our headcount increased by 774 employees, or 9%, in 2016, compared to 2015, primarily in research and development, driven by our 2016 business acquisitions, as well as higher services and sales headcount as we focus on delivering our new products to our customers.

2017 Compared to 2016

Research and development

Research and development expense, or R&D, decreased in 2017, compared to 2016, primarily due to a decline in personnel-related costs, including lower share-based compensation of $39.8 million primarily driven by lower expense from certain performance share awards, or PSAs, whose vesting is contingent upon the achievement of financial performance metrics or certain performance milestones, and lower variable compensation of $13.7 million. The decrease was partially offset by higher costs related to certain R&D project cancellations of $11.4 million and higher prototype costs of $10.4 million.

Sales and marketing

Sales and marketing expense decreased in 2017, compared to 2016, primarily due to a decline in personnel-related costs of $20.5 million, including lower variable compensation of $15.5 million primarily as a result of lower commissions expense and lower salaries and wages driven by a decrease in headcount as a result of the 2017 Restructuring Plan.

General and administrative

General and administrative expense increased in 2017, compared to 2016, primarily due to litigation settlement charges pursuant to a litigation settlement reached in November 2017 in connection with a legal proceeding of approximately $13.0 million, partially offset by a decline in other legal costs of $6.4 million.


Restructuring charges (benefits)

Restructuring charges (benefits) increased in 2017, compared to 2016, primarily due to severance and contract termination costs recorded under the 2017 Restructuring Plan.

2016 Compared to 2015

Research and development

Research and development expense increased in 2016, compared to 2015, primarily as a result of an increase in depreciation and amortization expense of $17.8 million, which was driven by higher capital expenditures related to research and development projects. Also contributing to the increase in research and development expense was $13.6 million of higher outside service costs, such as consulting, and higher facilities expense. To a lesser extent, personnel-related expenses increased due to higher salaries, wages, and fringe expense partially offset by lower bonusvariable compensation expense. The increase in salaries and wages was driven by a higher headcount of 331 from 3,723 at the end of 2015 to 4,054 inat the end of 2016, compared to 3,723 in 2015, as a result of our 2016 business acquisitions. These increases were partially offset by lower costs of $14.1 million related to the completion of development of new products.

Sales and marketing

Sales and marketing expense increased in 2016, compared to 2015, primarily due to an increase in personnel-related expenses of $26.6 million driven by higher salaries and wages related to an increase in headcount of 126 from 2,464 at the end of 2015 to 2,590 inat the end of 2016, compared to 2,464 in 2015 as well as an increase in share-based compensation expense, partially offset by lower bonus and commissionsvariable compensation expense.

General and administrative

General and administrative expense decreased in 2016, compared to 2015, primarily as a result of lower personnel-related expenses which includes a decline in share-based compensation and lower bonusvariable compensation expense, partially offset by higher salaries and wages. Additionally, facilities expense decreased in 2016, compared to 2015, due to the consolidation of our buildings in Sunnyvale, California. These declines were partially offset by an increase in outside services related to consulting projects as well as an increase in acquisition costs related to our 2016 business acquisitions.

Restructuring and other charges (benefits)

Restructuring and other charges (benefits) increased in 2016, compared to 2015, relateddue to severance costs in connection with our 2016 business combinations.

2015 Compared to 2014

Research and development

Research and development expense decreased in 2015, compared to 2014, as a result of lower headcount. Headcount declined from an average of 3,888 in 2014 to 3,724 in 2015, leading to a reduction in payroll costs and share-based compensation. In addition, outside consulting services decreased due to reduced consulting expenses, which was partially offset by an increase in depreciation expense on R&D equipment and bonus expense.

Sales and marketing

Sales and marketing expense decreased in 2015, compared to 2014. Average headcount increased from 2,360 in 2014 to 2,464 in 2015, however the mix of employees hired in 2015 was significantly different to 2014, which resulted in lower salary and bonus expense. Additionally, commissions expense decreased compared to 2014 as a result of the elimination of certain commission programs and a reduction in sales staff.

General and administrative

General and administrative expense decreased in 2015, compared to 2014 primarily as a result of higher litigation and investigation related costs incurred in 2014, in connection with the investigations into possible violations of the U.S. Foreign Corrupt Practices Act, and to a lesser extent, our patent litigation case with Palo Alto Networks. Additionally, we saw a decrease in general and administrative consulting fees, which was slightly offset by a higher bad debt expense amount.


Restructuring and other charges (benefits)

Restructuring and other charges (benefits) decreased in 2015, compared to 2014, due to higher charges recorded in 2014 in connection with our 2014 Restructuring Plan. During 2014, we implemented the 2014 Restructuring Plan and incurred restructuring charges of $166.2 million related to workforce reductions, contract terminations, project cancellations, and facility closures. The 2014 Restructuring Plan has been substantially completed as of December 31, 2014.

During the year ended December 31, 2015, we recorded $0.4 million of severance costs and a benefit of $1.0 million for facilities that were recorded in restructuring and other charges (benefits) in the Consolidated Statements of Operations, in connection with the 2014 Restructuring Plan. See Note 9, Restructuring and Other Charges (Benefits), in Notes to Consolidated Financial Statements in Item 8 of Part II of this Report for further discussion of our restructuring activities.

Impairment of goodwill

In 2014, we determined that the Security reporting unit's carrying value of goodwill exceeded the implied fair value of goodwill, resulting in a goodwill impairment charge of $850.0 million, which was recorded in the Consolidated Statement of Operations. No such charges were recorded in 2015 or 2016.

Share-Based Compensation

Share-based compensation expense associated with equity incentive awards, or awards, which include stock options; restricted stock units, or RSUs; restricted stock awards, or RSAs; and performance share awards, or PSAs; as well as our Employee Stock Purchase Plan, or ESPP, was recorded in the following cost and expense categories (in millions, except percentages):

20162017 Compared to 20152016

The effective tax rate for the taxfiscal year 20162017 was higher than 2015,2016, primarily due to an estimated $289.5 million of net income tax expense related to changes imposed by the Tax Act, which was enacted on December 22, 2017. Effective January 1, 2018, the Tax Act provides for significant changes to U.S. income tax law including the reduction of the U.S. federal corporate income tax rate from 35% to 21% and the creation of a changeminimum tax on foreign earnings. In addition, the Tax Act imposed a one-time transition tax on accumulated foreign earnings through December 31, 2017. The $289.5 million income tax expense includes an estimated tax charge of $431.2 million on the Company’s accumulated foreign earnings, which the Company has elected to pay over eight years, as described in Note 14, Income Taxes, in the geographic mixNotes to Consolidated Financial Statements in Item 1 of earnings. The effective tax rate for the tax year 2015 includes a benefitPart I of $13.2 million related to a change in the tax treatment of share-based compensation in our cost sharing arrangement.this Report.

As a result of recommendations by the Organisation for Economic Cooperation and Development (OECD) on Base Erosion and Profit Shifting (BEPS), certain countries in EMEA and APAC have either enacted new corporate tax legislation or have indicated that they are considering enacting such legislation in the near future. We expect the effect of these reform measuresfuture effective rate to potentially impact long-standing tax principles, particularly in regards to transfer pricing. Consequently, we expect global tax authorities to increasingly challenge our cost sharing and other intercompany arrangements, andtrend toward the related sourcing of taxable profits in global jurisdictions. In 2016, we entered into discussionsnewly enacted U.S. statutory rate with the UK tax authoritiesexception of the impacts of stock based compensation and the Australian tax authorities regarding corporate tax reform legislation enacted by those countries.

2015 Compared to 2014

The effective rate for the tax year 2015 was lower than 2014, primarily due to the income tax that was provided in 2014 on the non-deductible goodwill charge included in the pre-tax loss.one-time items.  In addition, the 2014 effective tax rate includes $52.8 million related to the gain on the sales of Junos Pulse offset by the release of the Company's valuation allowance attributable to investment losses.

Ourour effective tax rate could fluctuate significantly on a quarterly basis and could be adversely affected to the extent earnings are lower than anticipated in countries that have lower statutory rates and higher than anticipated in countries that have higher statutory rates. Our effective tax rate could also fluctuate due to changes in the valuation of our deferred tax assets or liabilities, or by changes in tax laws, regulations, or accounting principles, as well as certain discrete items. See Item 1A of Part II, Risk Factors of this Report for a description of relevant risks which may adversely affect our results.

On January 1, 2017, we adopted the new accounting pronouncement on Improvements to Employee Share-Based Payment Accounting, requiring excess tax benefits to be presented as an operating activity in the consolidated statements of cash flows. We applied this provision on a retrospective basis. During 2016 and 2015, $6.7 million and $12.3 million of excess tax benefits have been reclassified from financing to operating activities to conform to the current-year presentation.

Operating Activities

Our primary source of operating cash flows is cash collections from our customers. Our primary uses of cash from operating activities are for personnel-related expenditures, and other general operating expenses, as well as payments related to taxes, interest, and facilities.

2017 Compared to 2016

Net cash provided by operating activities increased in 2017, compared to 2016, primarily due to an increase in cash collections from customers in the first half of 2017 due to higher invoicing activity during the fourth quarter of 2016, partially offset by an increase in payments to suppliers, higher payments for restructuring activities and an increase in cash paid for income taxes.

2016 Compared to 2015

Net cash provided by operating activities increased by $213.5 million in 2016, compared to 2015. The increase was2015, primarily due to an increase in cash receivedcollections from customers in 2016 due to higher invoicing activity during the fourth quarter of 2015, partially offset by an increase in income taxes paid.


2015 Compared to 2014

Net cash provided by operating activities increased by $129.1 million in 2015, compared to 2014. The increase was primarily due to a decrease in cash payments for personnel-related expenditures, income tax paid in 2015, and an increase in cash received from customers, partially offset by an increase in cash payments to suppliers.

Investing Activities

Investing cash flows consist primarily of capital expenditures; investment purchases, sales, maturities and redemptions; and cash used for business combinations.

2017 Compared to 2016

Net cash used in investing activities decreased in 2017, compared to 2016, primarily due to lower payments for business combinations and capital expenditures and the receipt of $75.0 million in proceeds from the Pulse Note, partially offset by higher net purchases of available-for-sale securities.

2016 Compared to 2015

Net cash used in investing activities decreased by $58.6 million in 2016, compared to 2015. The decrease was primary due to a decrease in net purchases of available-for-sale investments, partially offset by an increase in cash used for business acquisitions in 2016.

2015 Compared to 2014

Net cash used in investing activities increased by $942.7 million in 2015, compared to 2014. The increase was primary due to lower net proceeds from available-for-sale securities in 2015, compared to 2014. In 2014, the sale of available-for-sale securities were higher in order to partially fund our accelerated share repurchase program. In addition, we completed our sale of Junos Pulse in 2014.

Financing Activities

Financing cash flows consist primarily of purchasesrepurchases and retirement of common stock, payment of cash dividends to stockholders, issuance and repayment of short-term and long-term debt, and proceeds from the issuance of shares of common stock through employee equity incentive plans.

2017 Compared to 2016

Net cash used in financing activities increased in 2017, compared to 2016, primarily due to an increase in repurchases and retirement of our common stock in 2017. In 2016, we raised $494.0 million from our 2019 Notes and 2024 Notes and repaid $300.0 million of our 2016 Notes.

2016 Compared to 2015

Net cash used in financing activities decreased by $351.8 million in 2016, compared to 2015. The decrease was primarily due to lower purchases and retirements of our common stock in 2016, partially offset by the payment of our 2016 Notes and a decrease in cash proceeds received from the issuance of long-term debt and the issuance of common stock in 2016.

2015 Compared to 2014

Net cash used in financing activities decreased by $1,242.8 million in 2015, compared to 2014. The decrease was primarily due to lower purchases and retirement of our common stock in 2015.

In February 2014 and 2015, our Board of Directors, which we refer to as the Board, approved a stock repurchase program that authorized us to repurchase up to $2.1 billion of our common stock, including $1.2 billion pursuant to an accelerated share repurchase program or("ASR"), and subsequent increases to the authorization totaling $1.8 billion ("Stock Repurchase Program.Program"). In October 2014 and July 2015,February 2017, the Board authorized a $1.3 billion and $500.0$500 million increase respectively, to the Stock Repurchase Program for a total of $3.9$4.4 billion. As of December 31, 2016, there was $219.7 million2017, we utilized all of the authorized funds remaining under the Stock Repurchase Program. In February 2017, the Board approved an incremental $500.0 million stock repurchase authorization under the Stock Repurchase Program.

In January 2018, our Board approved a new $2.0 billion share repurchase authorization ("2018 Stock Repurchase Program"), which replaces the previous authorization. Our Board also authorized us to enter into an ASR for an amount up to $750 million under the 2018 Stock Repurchase Program, and we expect to be opportunistic with our share repurchases in 2018.

In February 2018, we entered into ASR agreements with two financial institutions to repurchase an aggregate of $750 million of our common stock. The following table summarizesCompany made an up-front payment of $750 million pursuant to the ASR and received and retired an

As partfor an aggregate price of $600.0 million based on the market value of our common stock on the date of the transaction. We have an aggregate of $1.3 billion of authorized funds remaining under the 2018 Stock Repurchase Program, as of the filing date of this Annual Report on Form 10-K.

In addition, our Board declared a quarterly cash dividend of $0.18 per common stock to be paid on March 22, 2018 to stockholders of records as of the close of business on March 1, 2018. This reflects an increase of 80% compared to previous quarterly dividends. We intend to grow our dividend over time.

Future share repurchases under the 2018 Stock Repurchase Program we entered into two separate accelerated share repurchase agreements, or collectively, the ASR, with two financial institutions to repurchase $1.2 billion of our common stock. We made an up-front payment of $1.2 billion pursuant to the ASR to repurchase our common stock. The aggregate number of shares ultimately purchased was determined based on a volume weighted average repurchase price, less an agreed upon discount. The shares received with respect to the ASR have been retired. Retired shares return to authorized but unissued shares of common stock.

Future stock repurchases under our stock repurchase program will be subject to a review of the circumstances at that time and will be made from time to time in private transactions or open market purchases as permitted by securities laws and other legal requirements.

In 2016 and 2015, we paid cash dividends of $0.10 per share each quarter, totaling $152.5 million and $156.3 million per annum, respectively. The Our 2018 Stock Repurchase Program may be discontinued at any time. Additionally, the declaration and amount of any future cash dividends are at the discretion of the Board of Directors, or an authorized committee thereof, and will depend on our financial performance, economic outlook, and any other relevant considerations.

We completed our full commitment to return $4.1 billion of capital, inclusive of share repurchases and dividends, to stockholders by the end of 2016. Beginning in 2017, we intend to return approximately 50% of annual free cash flow to our stockholders, inclusive of share repurchases and dividends. Free cash flow is calculated as net cash provided by operating activities less capital expenditures.

Deferred Revenue

Deferred product revenue represents unrecognized revenue related to shipments to distributors that have not sold through to end-users, undelivered product commitments, and other shipments that have not met all revenue recognition criteria. Deferred product revenue is recorded net of the related costs of product revenue. Deferred service revenue represents customer payments made in advance for services, which include technical support, hardware and software maintenance, professional services, and training.

Total deferred revenue increased by $313.0 million to $1,481.1 million as of December 31, 2016, compared to $1,168.1 million as of December 31, 2015, primarily due to (1) an increase in deferred service revenue of $230.4 million driven by an increase in multi-year support agreements, which are billed in advance, and (2) an increase in product deferred revenue primarily due to higher deferrals related to subscription and software revenue arrangements and other shipments that have not met all revenue recognition criteria. In circumstances when costs are deferred, deferred product revenue is recorded net of the related costs of product revenue.

Off-Balance Sheet Arrangements

As of December 31, 20162017 and 2015,2016, we did not have any off-balance sheet arrangements, as defined in Item 303 (a)(4)(ii) of SEC Regulation S-K. It is not our business practice to enter into off-balance sheet arrangements. However, in the normal course of business, we enter into contracts consisting of guarantees of product and service performance, standby letters of credit for certain lease facilities and insurance programs. See Guarantees below for additional information regarding our guarantees.

Contractual Obligations

Our principal commitments consist of obligations outstanding under operating leases, purchase commitments, debt, and other contractual obligations. The following table summarizes our principal contractual obligations as of December 31, 20162017 and the effect such obligations are expected to have on our liquidity and cash flow in future periods (in millions):

As of December 31, 2016,2017, we had $209.2$256.6 million included in long-term income taxes payable in the Consolidated Balance Sheets for unrecognized tax positions. At this time, we are unable to make a reasonably reliable estimate of the timing of payments related to this amount due to uncertainties in the timing of tax audit outcomes. As a result, this amount is not included in the table above.


Revolving Credit Facility

On June 27, 2014,As of December 31, 2017, we entered into a Credit Agreementhave not borrowed any funds and we were in compliance with certain institutional lenders that provides for a five year $500.0 millionall covenants under our unsecured revolving credit facility that will expire in 2019, which enables borrowings up to $500.0 million, with anthe option to increase the amount of the credit facility by up to an additional $200.0 million, subject to certain conditions. Proceeds from borrowing made under the Credit Agreement may be used by us for working capital and general corporate purposes. Revolving loans may be borrowed, repaid and reborrowed until June 27, 2019, at which time all amounts borrowed must be repaid.

The Credit Agreement requires us to maintain a leverage ratio no greater than 3.0x and an interest coverage ratio no less than 3.0x during the term of the credit facility. In addition, the Credit Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict our ability and that of our subsidiaries to, among other things, grant liens, merge or consolidate, dispose of all or substantially all of its assets, change their accounting or reporting policies, change their business and incur subsidiary indebtedness, in each case subject to customary exceptions for a credit facility of this size and type. As of December 31, 2016, we were in compliance with all covenants in the Credit Agreement, and no amounts were outstanding.million. See Note 10, Debt and Financing, in Notes to Consolidated Financial Statements in Item 8 of Part II of this Report.Report for further information on our credit facility.

Guarantees

We have entered into agreements with customers that contain indemnification provisions relating to potential situations where claims could be alleged that our products solely, or in combination with other third party products, infringe the intellectual property rights of a third-party. As of December 31, 2016,2017, we recorded $28.9$20.4 million for such indemnification obligations in other accrued liabilities and other long-term liabilities on the Consolidated Balance Sheets. We also have financial guarantees consisting of guarantees of product and service performance and standby letters of credit for certain lease facilities and insurance programs and guarantees related to third-party customer-financing arrangements of $6.0$23.0 million and $15.8$6.0 million, as of December 31, 20162017 and December 31, 2015,2016, respectively.

Liquidity and Capital Resources

Liquidity and capital resources may be impacted by our operating activities as well as acquisitions, and investments in strategic relationships, that we have made or we may make in the future. Additionally, beginning in 2017 we intend to target a capital return policyrepurchases of approximately 50% of annual free cash flow, inclusive of share repurchases and dividends. To the extent we repurchase additional shares of our common stock, under our stock repurchase program or payand payment of cash dividends on our common stock, our liquidity may be impacted.stock. As of December 31, 2016, 87%2017, 91% of our cash, cash equivalents, and investment balances were held outside of the U.S., which may be subject Following the enactment of the Tax Act, we plan to U.S. taxes if repatriated.repatriate approximately $3.0 billion. We expect the new territorial tax system to provide us lower cost access to nearly all of our global free cash flow on an ongoing basis. Free cash flow is calculated as net cash provided by operating activities less capital expenditures. We intend to use the repatriated cash to invest in the business, support value-enhancing merger and acquisitions, or M&A, and fund our return of capital to stockholders.

In August 2016, we filed an automatic shelf registration statement with the SEC enabling us to offer for sale, from time to time, an unspecified amount of securities in one or more offerings and is intended to give us flexibility to take advantage of financing opportunities as needed or deemed desirable in light of market conditions. Our 2019 Notes and 2024 Notes were issued under an automatic shelf registration statement that we filed in August 2013 pursuant to a prospectus supplement filed with the SEC on February 24, 2016. Our 2020 Notes and 2025 Notes were issued under an automatic shelf registration statement pursuant to a prospectus supplement filed with the SEC on February 26, 2015, and our $350.0 million in principal amount of our 2024 Notes, which form a single series and are fully fungible with our 2024 Notes issued in 2016, were issued under an automatic shelf registration statement pursuant to a prospectus filed with the SEC on February 28, 2014. Any offerings of securities under our automatic shelf registration statement will be made pursuant to a prospectus. In addition, our Revolving Credit Facility will also provide additional flexibility for future liquidity needs.

We have been focused on managing our annual equity usage as a percentage of the common stock outstanding to align with peer group competitive levels and have made changes in recent years to reduce the number of shares underlying the equity awards we grant. For fiscal year 2016, we intended to target the number of shares underlying equity awards granted on an annual basis at 2.40% or less of our common stock outstanding on a pure share basis (where each option, RSU, RSA or PSA granted is counted as one share, and each PSA granted is counted based on target achievement). Based upon shares underlying our grants to date of options, RSUs, RSAs, and PSAs, we met this target for 2016.

Based on past performance and current expectations, we believe that our existing cash and cash equivalents, short-term, and long-term investments, together with cash generated from operations and access to capital markets and the revolving credit facility under the Credit Agreement will be sufficient to fund our operations, planned stock repurchases and dividends, capital expenditures, commitments, and other liquidity requirements and anticipated growth for at least the next twelve months. We believe our working capital is sufficient to meet our liquidity requirements for capital expenditures, commitments, and other liquidity requirements associated with our existing operations during the same period. However, our future liquidity and capital requirements may vary materially from those now planned depending on many factors, including, but not limited to:

levelto, our growth rate, the timing and mixamount we spend to support development efforts, the expansion of our product, sales and gross profit margins;

The value of our investments is subject to market price volatility. In addition, asTo minimize this risk, we maintain an investment portfolio of December 31, 2016, 87%various holdings, types, and maturities, which includes asset-backed securities, certificates of our cash, cash equivalents,deposit, commercial paper, corporate debt securities, foreign government debt securities, money market funds, mutual funds, time deposits, U.S. government agency securities, and investments were held outside of the United States, which may be subject to U.S. taxes if repatriated. Our investments are generally classified as available-for-sale and, consequently, are recorded on our Consolidated Balance Sheets at fair value with unrealized gains or losses reported as a separate component of accumulated other comprehensive loss. These investments are also reviewed to identify and evaluate indications of potential other-than-temporary impairments as discussed in Note 4, Cash Equivalents and Investments, in Notes to Consolidated Financial Statements in Item 8 of Part II of this Report.
government securities. At any time, a rise in interest rates could have a material adverse impact on the fair value of our investment portfolio. Conversely, a decline in interest rates could have a material impact on interest income from our investment portfolio. We do not currently hedge these interest rate exposures. We recognized immaterial gains and losses during the years ended December 31, 2016, 2015, and 2014, related to the sales of certain investments.

Foreign Currency Risk and Foreign Exchange Forward Contracts

Periodically, we use derivatives to hedge against fluctuations in foreign exchange rates. We do not enter into derivatives for speculative or trading purposes.
 
We use foreign currency forward contracts to mitigate variability in gains and losses generated from the re-measurement of certain monetary assets and liabilities denominated in non-functionalforeign currencies. These derivatives are carried at fair value with changes recorded in other (expense) income, net in our Consolidated Statements of Operations in the same period as the changes in the fair value from the re-measurement of the underlying assets and liabilities. These foreign exchange forward contracts typically have maturities of eighteen months or less.approximately one month.
 
Our sales and costs of product revenues are primarily denominated in U.S. Dollars. Our cost of service revenue and operating expenses are denominated in U.S. Dollars as well as other foreign currencies including the British Pound, theChinese Yuan, Euro, and the Indian Rupee, and the Japanese Yen.Rupee. Approximately 73% of such costs and operating expenses are denominated in U.S. Dollars. Periodically, we use foreign currency forward and/or option contracts to hedge certain forecasted foreign currency transactions to reduce variability in cost of service revenue and operating expenses caused by non-U.S. Dollar denominated operating expense and costs. In designing a specific hedging approach, we consider several factors, including offsetting exposures, significance of exposures, costs associated with entering into a particular hedge instrument, and potential effectiveness of the hedge. These derivatives are designated as cash flow hedges and have maturities of eighteen months or less. The effective portion of the derivative's gain or loss is initially reported as a component of accumulated other comprehensive loss and, upon occurrence of the forecasted transaction, is subsequently reclassified into the line item in the Consolidated Statements of Operations to which the hedged transaction relates. We record the ineffectiveness of the hedging instruments, which was immaterial during the year ended December 31, 2016 in other (expense) income, net on our Consolidated Statements of Operations. The change in operating expenses including cost of service revenue, research and development, sales and marketing, and general and administrative expenses, due to foreign currency fluctuations was a reduction to operating expenses of 0.1% and 1.1% for the year ended December 31, 2016.2017 and December 31, 2016, respectively. See Note 5,

Derivative Instruments, in Notes to Consolidated Financial Statements in Item 8 of Part II of this Report for further discussion of our derivative and hedging activity.

We have performed a sensitivity analysis as of December 31, 20162017, and as of December 31, 2016, using a modeling technique that measures the change in the amount of non-U.S. dollar cash, cash equivalents and marketable securities arising from a hypothetical 10% movement in the levels of foreign currency exchange rates relative to the U.S. dollar, with all other variables held constant. The foreign currency exchange rates we used were based on market rates in effect on December 31, 20162017. and December 31, 2016, respectively. The sensitivity analysis indicated that a hypothetical 10% movement in foreign currency exchange rates would change the amount of cash, cash equivalents, and investments we would report in U.S. Dollars as of December 31, 20162017 and December 31, 2016 by less than 1%., respectively.

Equity Price Risk

Our portfolio of publicly-traded equity securities and our non-qualified deferred compensation, (“NQDC”)or NQDC, plan, which may also hold publicly-traded equity securities, are inherently exposed to equity price risk as the stock market fluctuates.

We do not purchase our publicly-traded equity securities, classified as available-for-sale securities on our Consolidated Balance Sheets, for speculative purposes. As of December 31, 2016, our portfolio of publicly-traded equity securities had an estimated fair value of $4.6 million. A hypothetical 30% adverse change in the stock prices of our publicly traded equity securities would have no significant impact to the fair value of these investments.

Investments under the NQDC plan are considered trading securities2017 and are also reported at fair value on our Consolidated Balance Sheets. As of December 31, 2016, the total investments under our NQDC plan were $27.6 million and $21.0 million.million, respectively. A hypothetical 30% adverse change on the total investments under our NQDC plan would not have no significanta material impact to the fair value of these investments.investments, respectively.

We have also invested in privately-held companies. Depending on the nature of these investments, some can be carried at cost and others can be carried at fair value. Impairment charges onThe carrying values of our investments in privately-held companies were $11.2$83.0 million for the year ended December 31, 2016. The aggregate cost of our investments in privately-held companies was $62.7and $61.3 million as of December 31, 20162017. and December 31, 2016, respectively. The privately-held companies in which we invest can still be considered in the startup or development stages. These investments are inherently risky because the markets for the technologies or products these companies are developing are typically in the early stages and may never materialize. We could lose our entire investment in these companies. Our evaluation of investments in privately-held companies is based on the fundamentals of the businesses invested in, including, among other factors, the nature of their technologies and potential for financial return.

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.

In our opinion, Juniper Networks, Inc. maintained, 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 Juniper Networks, Inc. as of December 31, 2016, and 2015 and the related consolidated statements of operations, comprehensive income, changes in stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2016, of Juniper Networks, Inc. and our report dated February 24, 2017, expressed an unqualified opinion thereon.

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.
 
Management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2016,2017, based on the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control - Integrated Framework as published in 2013. Based on that assessment, management concluded that, as of December 31, 2016,2017, the Company's internal control over financial reporting was effective.
 
The effectiveness of the Company's internal control over financial reporting as of December 31, 20162017 has been audited by Ernst & Young LLP, the independent registered public accounting firm that audits the Company's Consolidated Financial Statements, as stated in their report preceding this report, which expresses an unqualified opinion on the effectiveness of the Company's internal control over financial reporting as of December 31, 2016.2017.

Note 2. Significant Accounting Policies

Use of Estimates

The preparation of the financial statements and related disclosures in accordance with U.S. GAAP requires the Company to make judgments, assumptions, and estimates that affect the amounts reported in the Consolidated Financial Statements and the accompanying notes. The Company bases its estimates and assumptions on current facts, historical experience, and various other factors that it believes are reasonable under the circumstances, to determine the carrying values of assets and liabilities that are not readily apparent from other sources. To the extent there are material differences between the Company's estimates and the actual results, the Company's future consolidated results of operation may be affected.

Cash, Cash Equivalents, and Investments

Cash and Cash Equivalents

Cash and cash equivalents consist of cash on hand, demand deposits with banks, highly liquid investments in money market funds, commercial paper, government securities, certificates of deposits, time deposits, and corporate debt securities, which are readily convertible into cash. All highly liquid investments purchased with original maturities of three months or less are classified as cash equivalents.

Investments in Available-for-Sale and Trading Securities

The Company's investments in publicly-traded debt and equity securities are classified as available-for-sale. Available-for-sale investments are initially recorded at cost and periodically adjusted to fair value in the Consolidated Balance Sheets. Unrealized gains and losses on these investments are reported as a separate component of accumulated other comprehensive loss in the Consolidated Balance Sheets. Realized gains and losses are determined based on the specific identification method and are reported in the Consolidated Statements of Operations.

Juniper Networks, Inc.
Notes to Consolidated Financial Statements (Continued)

The Company periodically evaluates its investments to determine if impairment charges are required. The Company considers various factors in determining whether to recognize an impairment charge, including the length of time the investment has been in a loss position, the extent to which the fair value has been less than the Company's cost basis, the investment's financial condition, and near-term prospects of the investee. If the Company determines that the decline in an investment's value is other than temporary, the difference is recognized as an impairment loss in its Consolidated Statements of Operations.

Juniper Networks, Inc.
Notes to Consolidated Financial Statements (Continued)


The Company's non-qualified compensation plan ("NQDC") is invested in mutual funds, which are classified as trading securities and reported at fair value in the Consolidated Balance Sheets. The realized and unrealized holding gains and losses are reported in the Consolidated Statements of Operations.

Investments in Privately-Held Companies

The Company has privately-held investments included in other long-term assets in the Consolidated Balance Sheets. These investments include debt and redeemable preferred stock securities that are carried at fair value, and non-redeemable preferred stock and common stock securities that are carried at cost. The Company’s investments in debt and redeemable preferred stock securities are classified as available-for-sale. Unrealized gains and losses on these investments are reported as a separate component of accumulated other comprehensive loss in the Consolidated Balance Sheets. The investments carried at cost and fair value are adjusted for any impairment determined to be other than temporary as the Company does not have a controlling interest and does not have the ability to exercise significant influence over these companies. These investments inherently carry higher risk as the marketmarkets for technologies or products manufactured by these companies are usuallygenerally in theirthe early stages at the time of the investment by the Company and such markets may never be significant. The Company measures the fair value of privately-held investments in debt and redeemable preferred stock securities using an analysis of the financial conditions and near term prospects of the investees, including recent financing activities and their capital structure. Realized gains and losses, if any, are reported in the Consolidated Statements of Operations.

Fair Value

Fair value is defined as the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining fair value, the Company considers the principal or most advantageous market in which it transacts, and considers assumptions that market participants would use when pricing the asset or liability. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

Level 1 – Quoted prices in active markets for identical assets or liabilities.

Level 2 – Quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. These inputs are valued using market based approaches.

Level 3 – Inputs are unobservable inputs based on the Company’s assumptions. These inputs, if any, are valued using internal financial models.

Derivatives

The Company uses derivatives to partially offset its market exposure to fluctuations in certain foreign currencies. The Company does not enter into derivatives for speculative or trading purposes.

The Company uses foreign currency forward contracts to hedge certain forecasted foreign currency transactions relating to operating expenses. These derivatives are designated as cash flow hedges. Execution of these cash flow hedge derivatives typically occurs every month with maturities of eighteen months or less. These derivatives are carried at fair value and the effective portion of the derivative's gain or loss is initially reported as a component of accumulated other comprehensive loss, and upon occurrence of the forecasted transaction, is subsequently reclassified into the costs of services or operating expense line item to which the hedged transaction relates. The Company records any ineffectiveness of the hedging instruments in other (expense) income,expense, net, on its Consolidated Statements of Operations. Cash flows from such hedges are classified as operating activities. All amounts within other comprehensive loss are expected to be reclassified into earnings within the next eighteen months.

Notes to Consolidated Financial Statements (Continued)

The Company also uses foreign currency forward contracts to mitigate variability in gains and losses generated from the re-measurement of certain monetary assets and liabilities denominated in non-functional currencies. These derivatives are carried at fair value with changes recorded in other (expense) income,expense, net in the Consolidated Statements of Operations in the same period as the changes in the fair value from the re-measurement of the underlying assets and liabilities. Cash flows from such derivatives are classified as operating activities. These

The Company presents its derivative assets and derivative liabilities on a gross basis in the Consolidated Balance Sheets. However, under agreements containing provisions on netting with certain counterparties of foreign exchange forward contracts, have maturities of eighteen months or less.subject to applicable requirements, the Company is allowed to net-settle transactions on the same date in the same currency, with a single net amount payable by one party to the other. The Company is neither required to pledge nor entitled to receive cash collateral related to these derivative transactions.

Inventory

Inventory consists primarily of component parts to be used in the manufacturing process and finished goods in-transit, and is stated at the lower of cost or market.net realizable value. Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis. A charge is recorded to cost of product when inventory is determined to be in excess of anticipated demand or considered obsolete. At the point of loss recognition, a new, lower-cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in the newly established cost basis.

Property and Equipment

Property and equipment are recorded at cost less accumulated depreciation. Depreciation is calculated using the straight-line method, over the estimated useful lives of the following assets:
 Estimated Useful Life (years)
Computers, equipment, and software1.5 to 7
Furniture and fixtures5 to 7
Building and building improvements7 to 40
Land improvements510 to 40
Leasehold improvementsLease term, not to exceed 10 years

Construction in progress is related to the construction or development of property and equipment that have not yet been placed in service for their intended use.

Goodwill and Other Long-Lived Assets

Goodwill represents the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recorded. The excess of the purchase price over the estimated fair value of net assets of businesses acquired in a business combination is recognized as goodwill. Goodwill is tested for impairment annually during the fourth quarter or more frequently if certain circumstances indicate the carrying value of goodwill is impaired. A qualitative assessment is first made to determine whether it is necessary to quantitatively test goodwill for impairment. This initial assessment includes, among others, consideration of macroeconomic conditions and financial performance. If the qualitative assessment indicates that it is more likely than not that an impairment exists, a quantitative analysis is performed by comparingdetermining the fair value of each reporting unit using a combination of the income approach and the market approach. Based on the outcome of the quantitative assessments, the Company compares the estimated fair valuesvalue of oureach reporting unitsunit with their respective carrying values, including goodwill. An impairment loss is recognized to the extent that the carrying amount of goodwill exceeds the asset's implied fair value.

Other intangible assets acquired in a business combination related to in-process research and development ("IPR&D") projects are considered to be indefinite-lived until the completion or abandonment of the associated research and development efforts. Indefinite-lived intangibles are not amortized into the results of operations but instead are evaluated for impairment. If and when development is complete, the associated assets would be deemed finite-lived and would then be amortized as cost of revenues over their respective estimated useful lives at that point in time. If the research and development project is abandoned, the acquired IPR&D assets are written off and charged to expense in the period of abandonment.

Long-lived assets, such as property, plant, and equipment, and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset, or asset group, to estimated undiscounted future cash flows expected to be generated by the asset, or asset group. An impairment charge is recognized by the amount by which the carrying amount of the asset, or asset group, exceeds its fair value.

Revenue Recognition

Revenue is recognized when all of the following criteria have been met:

Persuasive evidence of an arrangement exists. The Company generally relies upon sales contracts or agreements, and customer purchase orders to determine the existence of an arrangement.

Delivery has occurred. The Company uses shipping terms and related documents, or written evidence of customer acceptance, when applicable, to verify delivery of product obligations.

Sales price is fixed or determinable. The Company assesses whether the sales price is fixed or determinable based on the payment terms and whether the sales price is subject to refund or adjustment.

Collectability is reasonably assured. The Company assesses collectability based on creditworthiness of customers as determined by its credit checks, their payment histories, or changes in circumstances that indicate that collectability is not reasonably assured.

When sales arrangements contain multiple elements, the Company allocates revenue to each element based on a selling price hierarchy. The selling price for a deliverable is based on either vendor-specific objective evidence (“VSOE”) if available, third-party evidence (“TPE”) if VSOE is not available, or estimated selling price (“ESP”) if neither VSOE nor TPE is available. The Company then recognizes revenue on each deliverable in accordance with its policies for product and service revenue recognition. VSOE of selling price is based on the price charged when the element is sold separately. In determining VSOE, the Company requires that a substantial majority of the selling prices fall within a reasonable range based on historical discounting trends for specific products and services. TPE of selling price is established by evaluating largely interchangeable competitor products or services in stand-alone sales to similar situated customers. However, as the Company's products contain a significant element of proprietary technology and its solutions offer substantially different features and functionality, the comparable pricing of third-party products with similar functionality typically cannot be obtained and therefore TPE is not used. ESP is established considering multiple factors including, but not limited to pricing practices in different geographies and through different sales channels, gross margin objectives, internal costs, competitor pricing strategies, and industry technology lifecycles.

In multiple element arrangements where software deliverables are included, revenue is allocated to each separate unit of accounting for each of the non-software deliverables and to the software deliverables as a group using the relative selling prices of each of the deliverables in the arrangement based on the aforementioned selling price hierarchy. If the arrangement contains more than one software deliverable, the arrangement consideration allocated to the software deliverables as a group is then allocated to each software deliverable using the residual method when VSOE of fair value of the undelivered items exists. Under the residual method, the amount of revenue allocated to delivered elements equals the total arrangement consideration less the aggregate fair value of any undelivered elements. If VSOE of one or more undelivered items does not exist, revenue from the entire arrangement is deferred and recognized at the earlier of: (i) delivery of those elements or (ii) when VSOE can be established, and where maintenance service is the only undelivered element, the entire arrangement fee is recognized ratably over the maintenance service period.

The Company limits the amount of revenue recognition for delivered elements to the amount that is not contingent on the future delivery of products or services or subject to customer-specific return or refund privileges.

The Company records reductions to revenue for estimated product returns and pricing adjustments, such as rebates and price protection, in the same period that the related revenue is recorded. The amount of these reductions is based on historical sales returns and price protection credits, specific criteria outlined in rebate agreements, and other factors known at the time.

A portion of the Company's sales isare made through distributors under agreements allowing for pricing credits or rights of return. As reliable estimates of these credits or returns cannot be made, product revenue on sales made through these distributors is recognized upon sell-through as reported by the distributors to the Company. Deferred revenue on shipments to distributors reflects the effects of distributor pricing credits given and the amount of gross margin expected to be realized upon sell-through. Deferred revenue is recorded net of the related product costs of revenue.

Service revenues include revenue from maintenance, training, professional services, and software post-contract support ("PCS"). Maintenance is offered under renewable contracts. Revenue from maintenance service contracts is deferred and recognized ratably

73

over the contractual support period, which is generally one to three years. Revenue from training and professional services is recognized as services are completed or ratably over the contractual period, which is generally one year or less. Software PCS

Juniper Networks, Inc.
Notes to Consolidated Financial Statements (Continued)

includes technical support and provide software license updates. Software license updates provide customers with rights to unspecified software product upgrades, maintenance releases and patches released during the term of the support period. Revenue related to software PCS is recognized over the term of the PCS arrangement.

Allowance for Doubtful Accounts

The allowance for doubtful accounts is based on the Company's assessment of the collectability of customer accounts. The Company regularly reviews its receivables that remain outstanding past their applicable payment terms and establishes an allowance by considering factors such as historical experience, credit quality, and age of the accounts receivable balances, and current economic conditions that may affect a customer's ability to pay.

Warranty Reserves

The Company generally offers a one-year warranty on most of its hardware products, and a 90-day warranty on the media that contains the software embedded in the products. Warranty costs are recognized as part of the Company's cost of sales based on associated material costs, logistics costs, labor costs, and overhead at the time revenue is recognized. Material costs are estimated primarily based upon the historical costs to repair or replace product returns within the warranty period. Labor, logistics and overhead costs are estimated primarily based upon historical trends in the cost to support customer cases within the warranty period.

Contract Manufacturer Liabilities

The Company establishes a liability for non-cancelable, non-returnable purchase commitments with its contract manufacturers for carrying charges, quantities in excess of its demand forecasts, or obsolete material charges for components purchased by the contract manufacturers to meet the Company’s demand forecast or customer orders. The demand forecasts are based upon historical trends and analysis from the Company's sales and marketing organizations, adjusted for overall market conditions.

Research and Development

Costs to research, design, and develop the Company's products are expensed as incurred.

Software Development Costs

Capitalization of software development costs for software to be sold, leased, or otherwise marketed begins when a product's technological feasibility has been established and ends when a product is available for general release to customers. Generally, the Company's products are released soon after technological feasibility has been established. As a result, costs incurred between achieving technological feasibility and product general availability have not been significant.

The Company capitalizes costs associated with internal-use software systems during the application development stage. Such capitalized costs include external direct costs utilizedincurred in developing or obtaining the applications and payroll and payroll-related costs for employees, who are directly associated with the development of the applications.

Advertising

Advertising costs are charged to sales and marketing expense as incurred. Advertising expense was $19.9 million, $15.8 million, and $20.2 million, for 2017, 2016, and $19.2 million, for 2016, 2015, and 2014, respectively.

Foreign Currency

Assets and liabilities of foreign operations with non-U.S. Dollar functional currency are translated to U.S. Dollars using exchange rates in effect at the end of the period. Revenue and expenses are translated to U.S. Dollars using average exchange rates forthat approximate those in effect during the period. The resulting translation adjustments are included in the Company’s Consolidated Balance Sheets in the stockholders’ equity section as a component of accumulated other comprehensive loss. The Company records foreign exchange transaction gains and losses for assets and liabilities denominated in non-functional currencies. These remeasurement adjustments are recorded in other (expense) income,expense, net in the Consolidated Statements of Operations.

Loss Contingencies

The Company is subject to the possibility of various loss contingencies arising in the ordinary course of business. Management considers the likelihood of loss related to an asset, or the incurrence of a liability, as well as its ability to reasonably estimate the amount of loss, in determining loss contingencies. An estimated loss contingency is accrued when it is probable that an asset has been impaired or a liability has been incurred and the amount of loss can be reasonably estimated. The Company regularly evaluates current information available to determine whether such accruals should be adjusted and whether new accruals are required.

Share-Based Compensation

The Company measures and recognizes compensation cost for all share-based awards made to employees and directors, including employee stock options, restricted stock awards ("RSAs"), restricted stock units ("RSUs"), performance share awards ("PSAs") and employee stock purchases related to the Employee Stock Purchase Plan ("ESPP"). Share-basedFor service condition only awards, share-based compensation expense is based on the fair value of the underlying awards and amortized on a straight-line basis. For PSAs and market-based RSUs, share-based compensation expense is amortized on a straight-line basis netfor each separate vesting portion of estimated forfeitures.the awards. Upon adoption of the accounting standard described in the Recently Adopted Accounting Standard section below, the Company accounts for forfeitures as they occur.

The Company utilizes the Black-Scholes-Merton (“BSM”) option-pricing model to estimate the fair value of its stock options and ESPP shares. The BSM model requires various highly subjective assumptions that represent management's best estimates of volatility, risk-free interest rate, expected life, and dividend yield. The Company estimates expected volatility based on the implied volatility of market-traded options, on the Company's common stock, adjusted for other relevant factors including historical volatility of the Company’s common stock over the most recent period commensurate with the estimated expected life of the Company’s stock options and ESPP. The expected life of a stock option is based on historical experience of employee exercises and post-vesting termination behavior as well as the potential effect from options that have not been exercised. The expected life of ESPP approximates the offering period.

The Company determines the grant date fair value of its restricted stock units ("RSUs"), restricted stock awards ("RSAs"),RSUs, RSAs, and performance share awards ("PSAs")PSAs based on the closing market price of the Company’s common stock on the date of grant, adjusted by the present value of the dividends expected dividend.to be paid on the underlying shares of common stock during the requisite and derived service period as these awards are not entitled to receive dividends until vested.

For market-based RSUs, the Company estimates the fair value and derived service period using the Monte Carlo simulation option pricing model ("Monte Carlo model"). The determination of the grant date fair value and derived service periods using the Monte Carlo model is affected by the Company's stock price as well as various highly subjective assumptions that represent management's best estimates of volatility, risk-free interest rate, and dividend yield. The Company estimates expected volatility based on the implied volatility of market-traded options, on the Company's common stock, adjusted for other relevant factors including historical volatility of the Company’s common stock over the contractual life of the Company's market-based RSUs.

Provision for Income Taxes

Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts. Valuation allowances are recorded to reduce deferred tax assets to the amount that will more likely than not be realized.
The Company accounts for uncertainty in income taxes using a two-step approach to recognize and measure uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current to the extent that the Company anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes.

Concentrations of Risk

Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, investments, and accounts receivable. The Company invests only in high-quality credit instruments and maintains its cash, cash equivalents and available-for-sale investments in fixed income securities with several high-quality institutions. Deposits held with banks, including those held in foreign branches of global banks, may exceed the amount of insurance provided on such deposits. We mitigate the concentration of credit risk in our investment portfolio through diversification of the investments in various industries and limitasset classes, and limits to the amount of credit exposure to any single issuer.

issuer and credit rating.

The Company’s derivatives expose it to credit risk to the extent that counterparties may be unable to meet the terms of the agreement. To mitigate concentration of risk related to its derivatives, the Company establishes counterparty limits to major credit-worthy financial institutions. In addition, the potential risk of loss with any one counterparty resulting from this type of credit risk is monitored and the derivatives transacted with these entities are relatively short in duration. Therefore, the Company does not expect material losses as a result of defaults by counterparties.

Generally, credit risk with respect to accounts receivable is diversified due to the number of entities comprising the Company's customer base and their dispersion across different geographic locations throughout the world. The Company performs ongoing credit evaluations of its customers and generally does not require collateral on accounts receivable. During the years ended December 31, 2017, 2016, 2015, and 2014,2015, no single customer accounted for 10% or more of net revenues.

The Company relies on sole suppliers for certain of its components such as application-specific integrated circuits ("ASICs") and custom sheet metal. Additionally, the Company relies primarily on a limited number of significant independent contract manufacturers and outside design manufacturers for the production of its products. The inability of any supplier or manufacturer to fulfill supply requirements of the Company could negatively impact future operating results.

RecentRecently Adopted Accounting PronouncementsStandard

In November 2016,Share-based Compensation: On January 1, 2017, the Company adopted Financial Accounting Standards Board ("FASB") issued ASU No. 2016-18 (Topic 230) Statement of Cash Flow: Restricted Cash. The pronouncement requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, 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. The amendments of this ASU are effective for reporting periods beginning after December 15, 2017, with early adoption permitted. The standard must be applied retrospectively to all periods presented. The Company is currently evaluating the impact of adoption on the Consolidated Financial Statements.

In October 2016, the FASB issued ASU No. 2016-17 (Topic 810) Interests held through Related Parties that are under Common Control. The pronouncement amends the consolidation guidance on how a reporting entity that is the single decision maker of a VIE should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that VIE. The amendments of this ASU are effective for reporting periods beginning after December 15, 2016, with early adoption permitted. The standard must be applied retrospectively to all periods presented. The Company adopted the standard on January 1, 2017 and the adoption of this standard did not have a significant impact on the Company's Consolidated Financial Statements.

In October 2016, the FASB issued ASU No. 2016-16 (Topic 740) Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory, which will require companies to recognize, as opposed to defer, the tax effects from intercompany transfer of an asset, other than inventory, when the transfer occurs. Prior to the issuance of this ASU, companies were required to defer the income tax effects of intercompany transfers of assets until the asset has been sold to an outside party or otherwise recognized. ASU 2016-16 will still require companies to defer the income tax effects of intercompany inventory transactions. ASU 2016-16 will be effective for annual and interim reporting periods beginning after December 15, 2017 and is to be applied on a modified retrospective basis. Early adoption is permitted. The Company is currently evaluating the impact of adoption on the Consolidated Financial Statements.

In August 2016, the FASB issued ASU No. 2016-15 (Topic 230) Statement of Cash Flow: Classification of Certain Cash Receipts and Cash Payments. The pronouncement provides clarification guidance on certain cash flow presentation issues such as debt prepayment or debt extinguishment costs and contingent consideration payments made after a business combination and should be applied using a retrospective transition method for each period presented. For the provisions that are impracticable to apply retrospectively, those provisions may be applied prospectively as of the earliest date practicable. This pronouncement is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted. The Company is currently evaluating the impact that this standard will have on its Consolidated Statements of Cash Flows.

Notes to Consolidated Financial Statements (Continued)

In June 2016, the FASB issued ASU No. 2016-13 (Topic 326) Financial Instruments - Credit Losses. The pronouncement was issued to provide more decision-useful information about the expected credit losses on financial instruments and changes the loss impairment methodology. This pronouncement is effective for reporting periods beginning after December 15, 2019, and interim periods within those fiscal years, using a modified retrospective adoption method. A prospective transition approach is required for debt securities for which an other-than-temporary impairment had been recognized. Early adoption is permitted. The Company is currently evaluating the impact that this standard will have on its Consolidated Financial Statements and disclosures.

In March 2016, the FASB issued ASUAccounting Standards Update ("ASU") No. 2016-09 (Topic 718) Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"), which simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, forfeiture, statutory tax withholding requirements, and classification on the statement of cash flows. ASU-2016-09 is effective for interim and annual reporting periods beginning after December 15, 2016.The impact of the adoption on the Company's Consolidated Financial Statements was as follows:

Forfeitures: The Company adopted the standard on January 1, 2017 and elected to account for forfeitures as they occur using a modified retrospective transition method, rather than the current method of estimating forfeitures, resulting in a cumulative-effect net of tax adjustment of approximately $9.0 million, which increased the January 1, 2017 opening accumulated deficit balance.balance on the Consolidated Balance Sheets.

Income tax accounting: The Company is also required to record excess tax benefits and tax deficiencies related to stock- based compensation as income tax benefit or expense in the statement of operations prospectively when share-based awards vest or are settled. Upon adoption, the Company recognized the previously unrecognized excess tax benefits using the modified retrospective transition method, which resulted in no impact to the January 1, 2017 opening accumulated deficit balance. Thebalance as previously unrecognized excess tax effects were recorded as a deferred tax asset, which was fully offset by a valuation allowance. Without the valuation allowance, the Company’s deferred

Cash flow presentation of excess tax asset would have increased by $20.8 million.benefits: The Company alsois required to classify excess tax benefits along with other income tax cash flows as an operating activity either prospectively or retrospectively. The Company elected to apply the change in presentation to the statements of cash flows retrospectively and no longer classify the excess tax benefits from share-based compensation as a reductionfinancing activity. For 2016 and 2015, the Company reclassified $6.7 million and $12.3 million, respectively, of excess tax benefits from share-based compensation to operating cash flows.activities from financing activities.

Recent Accounting Standards Not Yet Adopted

Derivatives and Hedging:In August 2017, the FASB issued ASU No. 2017-12 (Topic 815) Derivatives and Hedging — Targeted Improvements to Accounting for Hedging Activities, which expands an entity's ability to hedge financial and nonfinancial risk components and amends how companies assess effectiveness as well as changes the presentation and disclosure requirements. The new standard is to be applied on a modified retrospective basis and is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact of adoption on the Consolidated Financial Statements.

Share-based Compensation:In May 2017, the FASB issued ASU No. 2017-09 (Topic 718) Compensation—Stock Compensation: Scope of Modification Accounting, which provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting. The new standard is effective on a prospective basis for interim and annual periods beginning after December 15, 2017, with early adoption permitted.

Amortization on Purchased Callable Debt Securities:In March 2017, the FASB issued ASU No. 2017-08 Receivables—Nonrefundable Fees and Other Costs(Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities which shortens the amortization period for the premium on certain purchased callable debt securities to the earliest call date. The ASU will not impact debt securities held at a discount. This standard is effective for annual reporting periods beginning after December 15, 2018, including interim reporting periods within those annual reporting periods, and is to be applied on a modified retrospective basis with early adoption permitted. The Company is currently evaluating the impact of adoption on the Consolidated Financial Statements.

Derecognition of Nonfinancial Assets: In February 2017, the FASB issued ASU No. 2017-05 Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets, which amends guidance on how entities account for the derecognition of a nonfinancial asset or an in substance nonfinancial asset that is not a business. This standard is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within those annual reporting periods, and is to be applied on either a retrospective or modified retrospective basis with early adoption permitted. The adoption of this standard will not have a material impact on the Consolidated Financial Statements.

Simplifying the Test for Goodwill Impairment: In January 2017, the FASB issued ASU No. 2017-04 (Topic 350) Intangibles—Goodwill and Other:Simplifying the Test for Goodwill Impairment, which removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Under the amended guidance, a goodwill impairment charge will now be recognized for the amount by which the carrying value of a reporting unit exceeds its fair value, not to exceed the carrying amount of goodwill. This ASU will be applied on a prospective basis and is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted for any impairment tests performed after January 1, 2017.

Definition of a Business:In January 2017, the FASB issued ASU No. 2017-01 (Topic 805) Business Combinations: Clarifying the Definition of a Business, which clarifies the definition of a business and assists entities with evaluating when a set of transferred assets and activities is a business.

Restricted Cash in Statement of Cash Flow:In November 2016, the FASB issued ASU No. 2016-062016-18 (Topic 815) 230)Derivatives Statement of Cash Flow: Restricted Cash, which provides guidance on the classification of restricted cash to be included with cash and Hedging: Contingent Putcash equivalents when reconciling the beginning of period and Call Options in Debt Instruments ("end of period total amounts on the statement of cash flows. The amendments of this ASU 2016-06"), which requires that embedded derivativesare effective for interim and annual periods beginning after December 15, 2017. The standard must be separated fromapplied retrospectively to all periods presented. The adoption of this standard will not have a material impact on the host contract and accounted for separately as derivatives if certain criteria are met. Onecash flow activity presented on the Company's Consolidated Statements of those criteria is that the economic characteristics and risksCash Flows.

Income Taxes on Intra-Entity Transfers of the embedded derivatives are not clearly and closely related to the economic characteristics and risks of the host contract (the “clearly and closely related” criterion).

This pronouncement is effective for interim and annual reporting periods beginning after December 15, 2017 and will be applied on a retrospective basis. The adoption of this standard will not have a material impact on the Company's Consolidated Statements of Cash Flows.

Credit Losses on Financial Instruments:In June 2016, the FASB issued ASU No. 2016-13 (Topic 326) Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments, which provides more decision-useful information about the expected credit losses on financial instruments and changes the loss impairment methodology. This pronouncement is effective for reporting periods beginning after December 15, 2019, and interim periods within those fiscal years.years, using a modified retrospective adoption method. Early adoption is permitted. The Company adoptedis currently evaluating the standard on January 1, 2017, and the adoption ofimpact that this standard did notwill have a significant impact on the Company'sits Consolidated Financial Statements.Statements and disclosures.

Leases:In February 2016, the FASB issued ASU No. 2016-02 (Topic 842), Leases ("ASU 2016-02"), which requires recognition of lease assets and lease liabilities on the balance sheet by the lessees for lease contractsleases classified as operating leases with a lease term of more than twelve months. This ASU 2016-02 should be applied on a modified retrospective basis and is effective for financial statements issued for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of adoption of this standard however itand has completed the assessment phase to determine the approach for implementing this standard. The adoption of this standard is expected to have a material impact on the Company's Consolidated FinancialBalance Sheets and disclosures. The Company is still evaluating the impact this standard will have on the Consolidated Statements and disclosures.of Operations.

Financial Instruments:In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments-Overall:Instruments—Overall: Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"), which requireschanges how entities measure equity investments to be measured at fair value withand present changes in fair value recognized in net income and simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. Entities may choose a practical expedient, to estimate the fair value of certain equity securities that do not have readily determinablefinancial liabilities measured under the fair value. If the practical expedient is elected, these investments would be recorded at cost, less impairment and subsequently adjusted for observable price changes.value option. The guidance also updates certain presentation and disclosure requirements. This ASU 2016-01 is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. This ASU is to be applied on a prospective basis for amendments related to equity securities without readily determinable fair values, and all other amendments in this standard will be applied on a modified retrospective basis. For equity securities without readily determinable fair values, we expect to elect the measurement alternative, defined as cost, less impairments, adjusted by observable price changes. The Company is currently evaluatingdoes not anticipate that the adoption of the amendments that will be applied on a modified retrospective basis will have a material impact that ASU 2016-01will have on itsthe Consolidated Financial Statements and disclosures.
In July 2015, the FASB issued ASU No. 2015-11 (Subtopic 330) - Simplifying the Measurement of Inventory ("ASU 2015-11"), which provides guidance to companies who account for inventory using either the first-in, first-out ("FIFO") or average cost methods. The guidance states that companies should measure inventory at the lower of cost and net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion,Statements.

disposal and transportation. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016. Early adoption is permitted. The Company adopted the standard on January 1, 2017, and the adoption of this standard did not have a significant impact on the Company's Consolidated Financial Statements.

Revenue: In May 2014, the FASB issued ASU No. 2014-09 (Topic 606) - Revenue from Contracts with Customers (“ASU 2014-09”), which provides guidance for revenue recognition. The FASB has also issued several amendments to the standard since the initial issuance. This ASUrecognition that will supersede the revenue recognition requirements in Topic 605, and most industry specific guidance. The standard's core principle for ASU 2014-09 is that revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. In doing so, the Company will need to use additional judgment and estimates than under the existing guidance. This ASU also requires more extensive disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB issued ASU 2015-14, which deferred the2014-09 is effective date of the new revenue standard from December 15, 2016 to December 15, 2017, with early adoption permitted as offor annual reporting periods beginning after December 15, 2016. Accordingly, the ASU and the amendments will be effective for the Company beginning fiscal year 2018.2017.

The Company intendsexpects to adopt the standardASU 2014-09 on January 1, 2018 retrospectively,under the modified retrospective approach, applying the amendments to each priorprospective reporting period presented. The Company's ability to adopt retrospectively is dependent on the completion of scoping and analysis of the necessary information, and being able to report each prior period within the date of adoption (or January 1, 2018).

The Company has completed a review of the accounting systems and processes required to apply the full retrospective method. Additionally, the Company has completed the majority of the assessment phase and documentation of new policies and is currently in the process of preparing prior-period financial statements, gathering data for the new disclosure requirements and evaluating its controls framework.periods. The Company does not expect a significant change in its control environment due to the adoption of the new standard, however, wethis assessment will continue to assess until datethe completion of adoption.the first reporting period.

Upon adoption, the Company expects a material impact to the opening balance sheet as of January 1, 20162018, related to the cumulative effect of adopting the standard, primarily as a result of the items discussed below. The Company will continue to assess and complete the review of all potential impacts of the standard and currently believesincluding the tax related impact. The most significantly impacted areas are the following:

Distributor sales: Under Topic 606, the Company will recognize revenue from sales to distributors upon delivery of the product to the distributor, rather than upon delivery of the product to the end customer. Rebates and incentives offered to distributors, which are earned when sales to end customers are completed, will be estimated at the point of revenue recognition and may require significant judgment and additional assumptions.recognition. At December 31, 2015,2017, the deferred revenue under Topic 605 related to shipments to distributors that had not sold through to end-users was $81.8is $68.0 million. Since the Company will be required to recognize revenue when control of the products transfer to the distributor Underunder Topic 606, the Company expects the majority of deferred revenue at December 31, 2015this amount will be eliminated as a cumulative effect adjustment of implementing Topic 606 as of January 1, 2016. The full impact2018.

Software Revenue: TheUnder Topic 605 the Company currently defersdeferred revenue for perpetualsoftware licenses where VSOE of fair value hashad not been established for undelivered items.items (primarily services). Under Topic 606, revenue for perpetualsoftware licenses will be recognized at the time of delivery as the VSOE requirement no longer applies and the Company can estimate stand-alone selling price for services. Currently, all term license revenue is deferred and recognized over the license term due to a lack of VSOE for services. Under Topic 606, term license revenue will be recognized at the time of delivery rather than ratably over the term period unless the ongoing services provide frequent, critical updates to the software, without which the software functionality would be rapidly diminished. At December 31, 2015,2017, deferred software license revenue under Topic 605 due to lack of VSOE and ratably recognized term licenses was $79.5is $144.5 million. The Company expects a significant proportionapproximately half of such deferred revenue willto be eliminated as a cumulative effect adjustment of implementing Topic 606 as of January 1, 2016. The full impact of the adjustment is still being analyzed by the Company.2018.

Contract Acquisition costs: Topic 606 requires the deferral and amortization of “incremental” costs incurred to obtain a contract where the associated contract duration is greater than one year. The primary contract acquisition cost for the Company are sales commissions. Under current U.S. GAAP, the Company expensesexpensed sales commissions. The change required by Topic 606 will result in the creation of an asset on the opening balance sheet atas a cumulative effect adjustment of implementing Topic 606 as of January 1, 2016. In each subsequent financial period, it is expected that this asset will increase or decrease proportionally with deferred revenues and will not have a material impact to the income statement.

The full impact of the adjustment is still being analyzed by the Company.2018.

Revenue Allocation: Similar to Topic 605, Topic 606 requires an allocation of revenue between deliverables, or performance obligations, within a transaction.an arrangement. Topic 605 restrictsrestricted the allocation of revenue that is contingent on future deliverables to current deliverables, however Topic 606 removes this restriction. ImpactIn addition, the nature of the performance obligations identified within a contract under Topic 606 as compared to Topic 605 will impact the allocation of the transaction price is still being assessed, however we dobetween product and services. The Company expects a reduction to the deferred service revenue balance as a cumulative effect adjustment of implementing Topic 606 as of January 1, 2018.

The Company will continue to assessCompany’s quarterly and/or annual Statement of Operations, however the impact of 606 as it works through the adoption in 2017, and there remain areas still to be fully concluded upon. Further, there remain ongoing interpretive reviews, which may alter the Company's conclusions and the financialexact impact of Topic 606.606 will be dependent on facts and circumstances that could vary from quarter to quarter.

Notes to Consolidated Financial Statements (Continued)

The Company's Level 2 available-for-sale fixed income securities are priced using quoted market prices for similar instruments or non-binding market prices that are corroborated by observable market data. The Company uses inputs such as actual trade data, benchmark yields, broker/dealer quotes, or alternative pricing sources with reasonable levels of price transparency which are obtained from quoted market prices, independent pricing vendors, or other sources, to determine the ultimate fair value of these assets. The Company's derivative instruments are classified as Level 2, as they are not actively traded and are valued using pricing models that use observable market inputs. The Company's policy is to recognize asset or liability transfers among Level 1, Level 2, and Level 3 at the beginning of the quarter in which a change in circumstances resulted in a transfer. During the years ended December 31, 20162017 and December 31, 2015,2016, the Company had no transfers between levels of the fair value hierarchy of its assets or liabilities measured at fair value.

All of the Company's privately-held debt and redeemable preferred stock securities, are classified as Level 3 assets due to the lack of observable inputs to determine fair value. The Company estimates the fair value of its privately-held debt investments on a recurring basis using an analysis of the financial condition and near-term prospects of the investee, including recent financing activities and the investee's capital structure. During the year ended December 31, 2016,2017, there were $12.9$11.0 million purchasesof unrealized gains related to privately-held debt securities.and redeemable preferred stock securities and no other significant activities related to Level 3 assets.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Certain of the Company's assets, including intangible assets, goodwill, and investments in privately-held companies (non-redeemablenon-redeemable preferred stock securities and common stock),stock securities, are measured at fair value on a nonrecurring basis, when they are deemed to be other-than-temporarily impaired.

Investments in privately-held companies,non-redeemable preferred stock and common stock securities, which are normally carried at cost, are measured at fair value on a nonrecurring basis due to events and circumstances that the Company identifies as significantlymaterially impacting the faircarrying value of the investments. The Company estimates the fair value of itsthese investments in privately-held companies using an analysis of the financial condition and near-term prospects of the investee, including recent financing activities and the investee's capital structure. Purchased intangible assets are measured at fair value primarily using discounted cash flow projections. These assets are classified as Level 3 due to the lack of observable inputs to determine fair value.
As of December 31, 2016, certain investments in privately-held companies with a carryingnon-redeemable preferred stock and common stock securities totaled $19.0 million, of which $6.8 million of investments had been remeasured at fair value of $1.6 million were impaireddue to an other-than-temporary decline in value and were written-down to their fair value of zero.

In the fourth quarter of 2017, the Company performed its annual goodwill impairment test for the Company's three reporting units: Routing, Switching, and Security forSecurity. For the years ended December 31, 2017, 2016, and 2015 and 2014, respectively. During the year ended December 31, 2016, the Company performed a quantitative assessment for each of the Company's three reporting units. This quantitative assessment was performed by determining the fair value of each reporting unit using a combination of the income approach and the market approach. Based on the outcome of the quantitative assessments, the Company determined that the fair value of each reporting unit exceeded its respective carrying value, resulting in no goodwill impairment. Therethere was no goodwill impairment during the year ended December 31, 2015.

In 2014, the Company re-aligned its go-to-market and research and development ("R&D") resources on projects with the highest potential for growth and continued to leverage its engineering efforts across its Routing, Switching, and Security products. In the fourth quarter of 2014, the Company began to implement a new Security strategy focused on network resiliency and performance based on the SRX platform. As a result, the Company rationalized its Security product portfolio including developing a new product roadmap and exiting certain point products, including the divestiture of Junos Pulse. These factors decreased the Company's short term and near term revenue and profitability forecasts of the Security reporting unit and the Company determined that the Security reporting unit's carrying value of goodwill exceeded the implied fair value of goodwill, resulting in a goodwill impairment charge of $850.0 million, which was recorded in the Consolidated Statement of Operations. The fair value was determined by using a combination of the income approach and the market approach. In determining the impairment amount, the fair value of the Security reporting unit was allocated to its assets and liabilities, including any unrecognized intangible assets, based on their respective fair values. Assumptions used in measuring the value of these assets and liabilities included the discount rates, customer renewal rates, and technology obsolescence rates used in valuing the intangible assets, and pricing of comparable transactions in the market in valuing the tangible assets.

Represents cumulative impact through fiscal year 2014 for the change in treatment of share-based compensation as a result of the U.S. Tax Court decision in Altera Corp. v. Commissioner, 145 T.C. No. 3 (2015).

On December 22, 2017, the U.S. Tax Cuts and Jobs Act (the “Tax Act”) was enacted into law. Effective January 1, 2018, the Tax Act provides for significant changes to U.S. income tax law, including the reduction of the U.S. federal corporate income tax rate from 35% to 21% and the creation of a minimum tax on foreign earnings. In addition, the Tax Act imposed a one-time transition tax on accumulated foreign earnings through December 31, 2017. The Company recognized a provisional income tax charge of $289.5 million, which is included as a component of the income tax provision on our Consolidated Statements of Operations.

Included in the provisional amounts is (i) a one-time transition tax of $431.2 million on the Company’s accumulated foreign earnings, which the Company has elected to pay over eight years, (ii) $134.5 million related to the re-measurement of the Company’s deferred tax assets at the revised U.S. statutory rates and (iii) $65.1 million of other accrued taxes on foreign distributable earnings, primarily related to withholding taxes and certain foreign timing differences. These impacts were partially offset by $341.3 million related to the reversal of deferred tax liabilities previously accrued on foreign earnings.

The Company’s tax expense of $431.2 million on the Company's accumulated foreign earnings is based on estimates of the effects of the Tax Act as the analysis requires significant data from the Company's foreign subsidiaries which is not regularly collected or analyzed, including the impact of certain foreign timing differences as well as the effect of foreign earnings upon the Company’s ability to utilize foreign tax credits.

Notes to Consolidated Financial Statements (Continued)

In addition, the provisional amount includes the remeasurement of certain U.S. deferred tax assets and liabilities of $134.5 million, foreign withholding taxes and the impact of certain foreign timing differences of $65.1 million. The Company has computed the amounts based on information available to it, including its expectation that the settlement of certain foreign basis differences will affect the amount of U.S. minimum tax upon reversal; however there is still uncertainty as to the application of the Tax Act.

As the Company collects and prepares the necessary data, interprets the Tax Act and reviews any additional guidance issued by the U.S. Treasury Department, state revenue and taxation authorities and other standard-setting bodies, the Company may make adjustments to the provisional amounts noted above which may materially impact its provision for income taxes from continuing operations in the period in which the adjustments are made. The accounting for the tax effects of the Tax Act will be completed in 2018.

In 2015, the United States Tax Court (the “Court”) issued an opinion favorable to Altera Corporation (“Altera”) with respect to Altera’s litigation with the Internal Revenue Service (“IRS”). The litigation relates to the treatment of share-based compensation expense in an inter-company cost-sharing arrangement with Altera’s foreign subsidiary. In its opinion, the Court accepted Altera’s position of excluding share-based compensation from its inter-company cost-sharing arrangement. As a result, the Company has reversed the inclusion of share-based compensation in its cost-sharing arrangement as a cumulative adjustment in the quarter ended September 30, 2015. Because this change to cost sharing increasesIn accordance with the Company's cumulative foreign earnings, approximately $70.3 millionTax Act, the effect of the gross income tax benefit associated with this change has been offset by an increase in income tax expense accrued upon the company’s foreign earnings. cumulative adjustment was remeasured.

In 2016, the IRS filed an appeal to the Altera decision rendered by the Court, which appeal is currently pending. The Company will continue to monitor ongoing developments and potential impacts to its financial statements.

Based on changes provided by the Tax Act, the Company re-measured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%.

As of December 31, 20162017 and 2015,2016, the Company had a valuation allowance on its U.S. domestic deferred tax assets of approximately $154.4$214.5 million and $146.2$154.4 million, respectively. The balance at December 31, 20162017 consisted of approximately $134.8$191.0 million and $11.9$19.7 million against the Company's California and Massachusetts deferred tax assets, respectively, which the Company believes are not more likely than not to be utilized in future years. The remaining deferred tax assets on which the Company recorded a valuation allowance of approximately $7.7$3.8 million related to losses that are capital in nature and may carry forward to offset future capital gains only. The valuation allowance increased in 2017 and 2016 and 2015 by $8.2$60.1 million and $1.7$8.2 million, respectively, primarily related to the change in California and Massachusetts R&D tax credits.

As of December 31, 2016,2017, the Company had federal and California net operating loss carry-forwards of approximately $55.9$66.7 million and $111.4$123.9 million, respectively. The California net operating loss carry-forwards of $111.4$123.9 million are expected to expire unused. The Company also had federal and California tax credit carry-forwards of approximately $2.7$2.6 million and $246.5$222.4 million, respectively. Approximately $20.8 million of the benefit from the California tax credit carry-forwards will be credited to additional paid-in capital when realized on the Company's income tax returns. Unused net operating loss carry-forwards will expire at various dates beginning in the year 2017.2018. The California tax credit carry-forwards will carry forward indefinitely.

The Company provides U.S. income taxes on the earnings of foreign subsidiaries unless the subsidiaries' earnings are considered indefinitely reinvested outside of the United States. The Company has made no provision for U.S. income taxes on approximately $2.4 billion of cumulative undistributed earnings of certain foreign subsidiaries through December 31, 2016. These earnings are considered indefinitely invested in operations outside of the U.S., as the Company intends to utilize these amounts to fund future expansion of its international operations. If these earnings were distributed to the United States in the form of dividends or otherwise, or if the shares of the relevant foreign subsidiaries were sold or otherwise transferred, the Company would be subject to additional U.S. income taxes (subject to an adjustment for foreign tax credits) and foreign withholding taxes. Determination of the amount of unrecognized deferred income tax liability related to these earnings is not practicable.

As of December 31, 2017, 2016, 2015, and 2014,2015, the total amount of gross unrecognized tax benefits was $264.5 million, $223.1 million, $216.1 million, and $199.2$216.1 million, respectively. As of December 31, 2016,2017, approximately $194.7$259.8 million of the $223.1$264.5 million gross unrecognized tax benefits, if recognized, would affect the effective tax rate. The increase in unrecognized tax benefits for the fiscal year 2017 was primarily related to changes in estimates resulting from the Tax Act.

As of December 31, 2017, 2016, 2015, and 2014,2015, the Company had accrued interest and penalties related to unrecognized tax benefits of $40.7 million, $31.3 million, $24.1 million, and $22.3$24.1 million, respectively, to other long-term liabilities in the Consolidated Balance Sheets. The Company recognized an expense for net interest and penalties of $8.5 million, $6.0 million, $2.5 million, and $2.8$2.5 million in its Consolidated Statements of Operations during the years ended December 31, 2017, 2016, 2015, and 2014,2015, respectively.

The Company engages in continuous discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. There is a greater than remote likelihood that the balance of the gross unrecognized tax benefits will decrease by approximately $3.7$48.0 million within the next twelve months due to lapses of applicable statutes of limitation and the completion of tax review cycles in various tax jurisdictions.

The Company conducts business globally and, as a result, Juniper Networks or one or more of its subsidiaries files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business the Company is subject to examination by taxing authorities throughout the world, including such major jurisdictions as the Netherlands, U.K., France, Germany, Japan, China, Australia, India, and the U.S. With few exceptions, the Company is no longer subject to U.S. federal, state and local, and non-U.S. income tax examinations for years before 2007.

The Company is currently under examination by the IRS for the 2007 through 2009 tax years. In March 2016, the IRS concluded its field audit and issued a final assessment. The Company is appealing this assessment. The Company regularly assesses the likelihood of an adverse outcome resulting from such examinations. As of December 31, 2016,2017, the Company believes the resolution of the audits is unlikely to have a material effect on its consolidated financial condition or results of operations.

In June 2016,December 2017, the California Franchise Tax Board (“FTB”)UK tax authorities concluded its audit of the 20042013 through 20062015 tax years. As a result of the closure of the California FTB audit, the gross unrecognized tax benefits was reduced by approximately $14.3 million,years, which did not affecthave a material impact to the Company’s effective tax rate. The Company is no longer subject to an audit of its California income taxes through the 2006 tax year.Company's financial statements.

The Company is also subject to separate ongoing examinations by the UK tax authorities for the 2013 through 20142016 tax years, the French tax authorities for the 2014 through 2015 tax years,year, the German tax authorities for the 2010 through 2013 tax years, the Australia tax authorities for the 2016 and 2017 tax year,years, and the India tax authorities for the 2003 tax year, the 2004 through 2008 tax years, and the 2009 through 20122014 tax years. As of December 31, 2016,2017, the Company is not aware of any other examinations by tax authorities in any other major jurisdictions in which it files income tax returns.

In 2008, the Company received a proposed adjustment from the India tax authorities related to the 2004 tax year. In 2009, the India tax authorities commenced a separate investigation of the Company's 2004 through 2008 tax returns and are disputing the Company's determination of taxable income due to the cost basis of certain fixed assets. The Company accrued $4.6 million in penalties and interest in 2009 related to this matter. The Company understands that in accordance with the administrative and judicial process in India, the Company may be required to make payments that are substantially higher than the amount accrued in order to ultimately settle this issue. The Company strongly believes that any assessment it may receive in excess of the amount accrued would be inconsistent with applicable India tax laws and intends to defend this position vigorously.

The Company is pursuing all available administrative remedies relative to these matters. The Company believes that it has adequately provided for any reasonably foreseeable outcomes related to these proposed adjustments and the ultimate resolution of these matters is unlikely to have a material effect on its consolidated financial condition or results of operations; however, there

Basic net income per share is computed using net income (loss) available to common stockholders and the weighted-average number of common shares outstanding for the period. Diluted net income per share is computed using net income (loss) available to common stockholders and the weighted-average number of common shares outstanding plus potentially dilutive common shares outstanding during the period. Dilutive potential common shares consist of common shares issuable upon exercise of stock options, issuances of ESPP, and vesting of RSUs, RSAs, and PSAs. The Company includes the common shares underlying PSAs in the calculation of diluted net income per share only when they become contingently issuable. Anti-dilutive shares are excluded from the computation of diluted net income per share.

Unconditional Purchase Obligations

Unconditional purchase obligations consist of agreements that include firm and non-cancelable terms to transfer funds in the future for fixed or minimum amounts or quantities to be purchased at fixed or minimum prices.

Operating Leases

The Company leases its facilities and certain equipment under non-cancelable operating leases that expire at various dates through March 2026.2028. Certain leases require the Company to pay variable costs such as taxes, maintenance, and insurance and include renewal options and escalation clauses. Rent expense for 20162017, 20152016, and 20142015 was approximately $39.3 million, $37.9 million,$43.2 million, and $46.043.2 million, respectively.

Other Lease Arrangement

OnIn July 10, 2015, the Company entered into a lease arrangement through March 2026 in which the Company has the option to extend the term of the lease for up to an additional twenty years in increments of either five years or ten years, for approximately 63,000 square feet of space in the State of Washington. As of December 31, 2016, the total payment under the lease agreement over the ten-year term is approximately $115.5 million of which $61.6 million is included in other-long term liabilities on the Consolidated Balance Sheets. The lease agreement provides the Company with a tenant allowance of $6.0 million to be used for tenant leasehold improvements. Any unused tenant allowance may be applied as a credit to the rent payment. During the year ended December 31, 2016, the Company received reimbursement for tenant allowances of $4.4 million. The space is used, among other things, to consolidate certain of the Company's laboratory operations currently located in Sunnyvale, California.

Due to certain contractual obligations during the construction period, the Company was deemed the owner of the property during that period. As of December 31, 2015, theThe Company capitalized the construction costs by recording a build-to-suit lease asset under construction in progress of $45.6 million, which is a component of property and equipment, net, and a corresponding build-to-suit financing liability, which is a component of other long-term liabilities, in the Consolidated Balance Sheets. Through the date of construction completion, the Company recorded additional construction costs and a corresponding build-to-suit financing liability of $15.3 million.

liability. Upon the completion of construction in April 2016, the Company assessed whether the arrangement qualified under the sale-leaseback accounting guidance. The Company concluded that it had a certain form of continuing economic involvement in the facility, which precluded sale-leaseback accounting treatment. As a result, a total of $60.9 million of costs capitalized were placed in service and are being depreciated over the lease term. As of December 31, 2017, the total payment under the lease agreement over the ten-year term is approximately $112.0 million of which $62.6 million is included in other-long term liabilities on the Consolidated Balance Sheets.

Purchase Commitments with Contract Manufacturers and Suppliers

In order to reduce manufacturing lead times and in the interest of having access to adequate component supply, the Company enters into agreements with contract manufacturers and certain suppliers to procure inventory based on the Company's requirements. A significant portion of the Company's purchase commitments arising from these agreements consists of firm and non-cancelable commitments. These purchase commitments totaled $686.2$615.2 million as of December 31, 2016.

Legal Proceedings

Investigations

The Company previously disclosed that the U.S. Securities and Exchange Commission ("SEC") and the U.S. Department of Justice ("DOJ") arewere conducting investigations into possible violations by the Company of the U.S. Foreign Corrupt Practices Act ("FCPA"). The Company ishas been cooperating with these agencies regarding these matters. In the fourth quarter of 2017, the DOJ notified the Company that the DOJ has closed its investigation related to these matters without taking any action against the Company. The Company’s Audit Committee, with the assistance of independent advisors, has been investigating and conducting a thorough review of possible violations of the FCPA, and has made recommendations for remedial measures, including employee disciplinary actions in foreign jurisdictions, which the Company has implemented and continues to implement. The Company is unable to predict the duration, scope or outcome of the ongoing SEC and DOJ investigations,investigation, but believes that an adverse outcome is reasonably possible. However, the Company is not able to estimate a reasonable range of possible loss. The SEC and/or DOJ could take action against the Company or the Company could agree to settle. In such event, the Company could be required to pay substantial fines and sanctions and/or implement additional remedial measures; in addition, it may be determined that the Company violated the FCPA.

Other Litigations and Investigations

In addition to the investigations discussed above, the Company is involved in other investigations, disputes, litigations, and legal proceedings. The Company records an accrual for loss contingencies for legal proceedings when it believes that an unfavorable outcome is both (a) probable and (b) the amount or range of any possible loss is reasonably estimable. The Company intends to aggressively defend itself in these matters, and while there can be no assurances and the outcome of these matters is currently not

determinable, the Company currently believes that none of these existing claims or proceedings are likely to have a material adverse effect on its financial position. Notwithstanding the foregoing, there are many uncertainties associated with any litigation and these matters or other third-party claims against the Company may cause the Company to incur costly litigation and/or substantial settlement charges. In addition, the resolution of any intellectual property litigation may require the Company to make royalty payments, which could adversely affect gross margins in future periods. If any of those events were to occur, the Company's business, financial condition, results of operations, and cash flows could be adversely affected. The actual liability in any such matters may be materially different from the Company's estimates, if any, which could result in the need to adjust the liability and record additional expenses.

The Company records an accrual for loss contingencies for legal proceedings when it believes that an unfavorable outcome is both (a) probable and (b) the amount or range of any possible loss is reasonably estimable. The Company has not recorded any accrual for loss contingencies associated with such legal proceedings or the investigations discussed above.
