ITEM 1. BUSINESS

Infinera Corporation (“we,” “us,” “our” or “Infinera”) is a leader in optical transport networking solutions, providing equipment, software and services to telecommunications service providers, internet content providers (“ICPs”), cable providers, wholesale and enterprise carriers, research and education institutions, enterprise customers, and government entities across the globe. Optical transport networks are deployed by customers facing significant demand for optical bandwidth prompted by increased use of high-speed internet access, business Ethernet services, mobile broadband, cloud-based services, high-definition video streaming services, virtual and augmented reality, and the Internet of Things (IoT).

Our optical transport systems are highly scalable, flexible and open, built using a combination of internally manufactured and third-party components. Technologically, a key element of our systems are optical engines, which comprise large-scale photonic integrated circuits (“PICs”) and digital signal processors (“DSPs”). We optimize the manufacturing process by using indium phosphide to build our PICs, which enables the integration of a large amount of optical functions onto a set of semiconductor chips. This large-scale integration of our PICs and advanced DSPs allow us to deliver on the features that customers care about the most, including cost per bit, power and space. In addition, our optical engines are designed to increase the capacity and reach performance of our products by leveraging coherent optical transmission.

Over the past few years, we have significantly increased the number of products we offer, evolving from focusing entirely on the long-haul and subsea markets to offering a more complete suite of solutions that span the long-haul, subsea, DCI and metro markets. In late 2014, we expanded our addressable market by introducing the Cloud Xpress platform for the DCI market to meet a growing need for metro-reach optical interconnections between data centers. We introduced the Cloud Xpress 2 in mid-2017, which further optimizes capacity, space and power, all key elements our ICP customers' value.

In the second half of 2015, we entered the metro market with the acquisition of Transmode AB (“Transmode”), a leader in metro packet-optical applications, based in Stockholm, Sweden. Entering into the metro market expanded our addressable market and enabled us to offer a more complete portfolio of solutions, particularly to existing long-haul customers that also build metro networks. We have expanded our suite of metro solutions by both enhancing our XTM Series platforms and also utilizing our optical engines to deliver Cloud Xpress, XT and XTC Series platforms.

In 2017, we began shipping two new platforms based on our new generation of technology. First, we introduced a series of new products powered by the Infinite Capacity Engine (ICE), a technology which delivers multi-terabit opto-electronic subsystems powered by our fourth-generation PIC and next-generation FlexCoherent DSP (the combination of which we refer to as “ICE4”). The Infinite Capacity Engine enables different subsystems that can be customized for a variety of network applications across our product portfolio, spanning the long-haul, subsea, datacenter interconnect (“DCI”) and metro markets. Second, we released our next-generation XTM Series platform, which leverages 16QAM modulation technology and is optimized for bandwidth-intensive applications at the metro edge.

Our optical portfolio is designed to be managed by a single network management system. We also provide capabilities to enable programmability of our Intelligent Transport Networks with our technologies, such as Instant Bandwidth, which when combined with our differentiated hardware solutions, enable customers to turn on bandwidth as needed by activating a software license. Additionally, our Xceed Software Suite is a multi-layer management and control platform that simplifies customer operations and enables customers to leverage the scalability, flexibility and openness of our Intelligent Transport Networks to deliver services while efficiently using their network resources.

We believe our portfolio of solutions benefits our customers by providing a unique combination of highly scalable capacity and features that address various applications and ultimately simplify and automate optical network operations.

We were incorporated in December 2000 and originally operated under the name “Zepton Networks.” We are incorporated in the State of Delaware. Our principal executive offices are located at 140 Caspian Court, Sunnyvale, CA 94089. Our telephone number is (408) 572-5200. “Infinera,” “Infinera DTN-X,” “FlexCoherent,” “Infinera FlexILS” and “Infinera Instant Bandwidth” are trademarks or service marks of Infinera Corporation in the United States, certain other countries and/or the European Union. Any other trademarks or trade names mentioned are the property of their respective owners.

Industry Background

Optical transport networking equipment carries digital information using light waves over fiber optic cables. With the advent of wavelength division multiplexing (“WDM”) systems, data is transmitted by using multiple wavelengths of light using different frequencies or colors over a single optical fiber. Customers deploy WDM systems to carry information between continents, across countries, between cities and within metropolitan areas, and in some cases all the way to the end-user. Fiber optic networks are generally capable of carrying most types of communications traffic. We believe that a number of trends in the communications industry are driving demand for large amounts of network bandwidth and ultimately will increase demand for optical transport networking systems. These trends include:


•	growth of cloud services;


•	growth of bandwidth-intensive services like streaming high-definition video services;


•	increasing use of connected virtual and augmented reality devices;


•	proliferation of mobile services of Wi-Fi, 4G and future growth of 5G; and


•	rise of the Internet of Things (IoT), driving massive growth in the number of network-connected devices.

As network traffic grows, customers add transmission bandwidth to existing optical networks or deploy new systems to address bandwidth demands and offer expanded services to end-users. In particular, consumers and businesses increasingly rely on the cloud for their application needs across compute, storage and network functions. As cloud adoption increases, large network operators are experiencing a magnification effect on incoming traffic, such that a single request from an end-user can generate many times the amount of traffic between data centers as compared to the amount of traffic generated by the original request.

We believe we are in the midst of a shift in network architectures distinguished between addressing massive growth of server-to-server traffic between data centers and public internet user-to-data traffic as deployed by traditional service providers. To manage server-to-server traffic growth, our customers seek high capacity, scalable, disaggregated solutions designed to accommodate point-to-point traffic patterns. Infrastructure to address this demand is focused on minimizing power and space and being cost-optimized. In contrast, traditional service providers require high capacity solutions with more flexibility in their integrated network platforms to aggregate dataflows and add and drop traffic at various points across their networks. These customers require protection schemes and a larger variety of interfaces to address their end customer needs. Our solutions serve both the point-to-point applications driven by increasing data center traffic and the more traditional mesh-oriented switched transport networks.

We believe our customers seek the following solutions to increase their revenue and/or expand their service offerings:


•	high-bandwidth solutions that scale optical transmission bandwidth to meet increasing demand while providing wide-ranging granularity for service efficiency;


•	efficient solutions with the right mix of disaggregated and integrated systems that optimize performance and increase reliability while reducing physical space and power consumption, leading to lower operational expenses;


•	easy-to-use solutions that are highly programmable and open, which help reduce the time and complexity of deploying new transmission bandwidth;


•	improved integration between packet or Internet Protocol equipment such as routers and optical transport networking equipment; and


•	strong encryption at the transport layer processed using hardware at line-rate speeds.

Strategy

Our goal is to be the preeminent provider of optical transport networking systems in the world. Key aspects of our strategy include:


•	Expanding business with existing customers and winning new customers. We have recently introduced multiple new products and expect to release additional products in 2018, which we believe will enable us to address a broader portion of the optical market, expand business with current customers and win new customers.

•

Accelerating the cadence at which new products are brought to market. Historically, we have brought to market new generations of our optical engine, which includes PICs and DSPs, approximately every five years. In response to the pace of architectural transitions and customer demand, we have accelerated our planned cadence of delivering new generations of ICE-based products in order to take full advantage of rapid growth in bandwidth requirements and market shifts. We intend to continually invest in key

technologies such as optical engines and software in order to enhance the performance, scalability and economic advantages of our products.

•

Aligning customer success with our success. When our customers are successful we are as well. For example, our Instant Bandwidth solution enables customers to activate additional bandwidth when needed. Additionally, our global customer services team is committed to making our customers successful by providing the highest quality support services to deploy, operate and maintain their networks. We believe providing the most reliable products and differentiated customer experiences contribute to customer success and are major differentiators.

•

Driving cost structure optimization. In delivering innovative solutions to our customers, we are committed to cost structure efficiencies that enhance our ability to invest in research and development and drive profitability. In particular, we believe our vertically integrated manufacturing capabilities serve as a competitive advantage from a technology and supply chain perspective, and financially, enable a lower cost structure and thus, higher profitability.

•

Utilizing automation to deliver differentiated solutions. We believe we lead the industry in ease of use and automation, facilitated by our software capabilities. We continue to invest in our differentiated technologies, including enhancing capabilities of our Instant Bandwidth offerings. We are extending the management and control capabilities across our entire product portfolio with the Xceed Software Suite, which enables customers to efficiently utilize network resources. Additionally, based on customers’ desire for more programmable networks, we have added open application programming interfaces (“APIs”) to our solutions to enable our customers to be more agile and automate operations.

Customers

Our customer verticals include:


•	Tier-1 carriers for domestic and international networks;


•	Tier-2 and Tier-3 carriers;


•	ICP and data center operators;


•	multiple system operators/cable providers;


•	wholesale and enterprise carriers;


•	submarine network operators;


•	enterprise customers; and


•	research and education/government entities.

We sell our products directly to customers who are end-users and to channel partners that sell on our behalf. We do not have long-term sales commitments from our customers. One customer, which completed a merger in late 2017, was a combination of two of our historically larger customers who merged in 2017 and accounted for approximately 18% of our revenue in 2017. These two historically larger customers each individually accounted for approximately 16% and 8% of our revenue in 2016, respectively, and approximately 17% and 13% of our revenue in 2015, respectively. No other customers accounted for over 10% of our revenue for these periods.

Technology

Infinera Intelligent Transport Network Architecture

We were founded with a vision of enabling an infinite pool of intelligent bandwidth upon which the next communications infrastructure is built. We have focused our efforts and capital on developing application-optimized platforms that enable customers to create rich end-user experiences delivered through efficient, high-bandwidth transport characterized by the following attributes:

•

Scalable. The proliferation of data centers, rise of cloud computing, increasing consumption of video and growth in mobile access is fundamentally changing traffic characteristics in operator networks. We currently deliver terabit class coherent, sliceable super-channels, which allow a massive pool of bandwidth to be provisioned in a single operation. Sliceable photonics enable network operators to benefit from high capacity super-channels and also achieve wavelength granularity for wide-ranging control of the network.


•	Flexible. We offer a mix of integrated and disaggregated platforms to reduce complexity and enable flexibility as network architectures evolve. There are varying customer preferences as some service providers continue to favor integrated multi-service mesh networks while traffic driven by ICPs is increasingly serviced by disaggregated platforms that address point-to-point connections.

•

Open. Network operators are facing intensifying competition to meet customer demand for immediate bandwidth and better visibility into the network. Our Intelligent Transport Networks feature highly programmable platforms with SDN APIs enabling networks to be open; this helps simplify end to end multi-layer provisioning. Additionally, there is growing demand from certain customers for line systems that are open, which entails having the ability to use transponders from one vendor over a different vendor’s line system. We are addressing this dynamic, both by seeking opportunities to sell our transponders over other vendors’ line systems and also offering our own open platform that supports both fixed and flexible grid technology, thus allowing a seamless mix of transponders from multiple vendors.

Infinera Optical Engines

We believe our optical engines, with the latest version being ICE4, are key to our value proposition and a competitive advantage. Technologically, we are able to deliver multi-terabit class coherent super-channels through PICs in systems that significantly exceed reliability standards. Additionally, DSPs enable network operators to utilize coherent technologies to enable higher data capacity transmissions over existing optical fiber infrastructure. We have integrated advanced coherent technologies onto our FlexCoherent DSP in ICE4, such as cutting-edge Nyquist subcarriers and soft-decision forward error correction gain sharing techniques. We use third-party components for specific applications such as multi-service packet within metro platforms. Financially, we believe our technology approach enables improved manufacturing economics for optical networking, allowing future optical transport cost reductions to be viably sustained on a cost curve defined by volume manufacturing efficiencies and greater functional integration.

Super-Channels and Sliceable Photonics

Infinera’s DTN-X and Cloud Xpress Family of products are designed to support multiple channels, each up to 200 Gb/s capacity, in a single line card or unit depending on the platform form factor. This pool of bandwidth can either be managed as a single super-channel, with currently up to 1.2 Tb/s that can be deployed in a single operation or sliced into smaller increments to allow operators more flexibility. In order to achieve the same system capacity, competitive solutions require the installation of multiple discrete line modules or units, each turned up with its own operation. Super-channels result in competitive advantages leading to lower operational costs and long-term system reliability, as well as significant reductions in installation time. Our ICE4 technology combines the benefits of super-channels with the capability of being able to slice capacity into lower unit increments such as 100 Gb/s. Each increment can be tuned and routed in multiple separate directions, with each fully tuned to its own flexible grid frequency as well as having its own coherent modulation profile. This significantly reduces the number of modules required in networks, resulting in lower total cost of ownership and a highly flexible optical transport network.

Infinera Instant Bandwidth

Infinera Instant Bandwidth enables customers to license a super-channel pool of bandwidth in smaller increments such as 100 Gb/s. With Infinera Instant Bandwidth technology, which is available on the Infinera DTN-X XTC Series, DTN-X XT Series, DTN-X XTS Series, Cloud Xpress Family and XTM Series platforms, customers can provision additional transmission capacity on demand without the deployment of any incremental equipment. The Infinera Instant Bandwidth technology is uniquely enabled by our hardware, providing customers the ability to adopt a success-based business model for network growth.

Security and Software-enabled Automation

Unified network management, control and security is critical to achieving service simplicity. Our Xceed Software Suite is a portfolio of products that combines an open, multi-layer SDN control platform with applications that enhance revenue sources while increasing network efficiency. Our Xceed Software Suite is designed for multi-layer networks and unified SDN control across end-to-end transport networks, helping customers automate and simplify operations. Our advanced security capabilities within the Infinite Capacity Engine (ICE) are designed to provide strong encryption at the transport layer processed using hardware at line-rate speeds, with the highest levels of data protection.

Competition

Our current technologies and platforms support the long-haul, subsea, DCI and metro markets. The optical transport networking equipment market is highly competitive and competition in the markets we serve is based on any one or a combination of the following factors:


•	price and other commercial terms;


•	functionality;


•	existing business and customer relationships;


•	the ability of products and services to meet customers’ immediate and future network requirements;


•	power consumption;


•	heat dissipation;


•	form factor or density;


•	installation and operational simplicity;


•	service and support;


•	security and encryption requirements;


•	scalability and investment protection; and


•	product lead times.

Competition in the optical transport equipment market is intense. In the long-haul market, our main competitors include WDM systems suppliers such as Ciena, Coriant, Huawei, Nokia and ZTE. In the metro market, we face the same competitors as in long-haul, plus Cisco, Adva Optical Networking and Fujitsu. In addition, we have started to face competition in the DCI market from vendors that are selling optical components directly to customers, as opposed to WDM systems. In addition to our current competitors, other companies have, or may in the future, develop products that are, or could be, competitive with our products. We also may encounter competitor consolidation in the markets in which we compete, which could lead to a changing competitive landscape, capabilities and market share, and could impact our results of operations.

Some of our competitors have substantially greater name recognition, technical, financial and marketing resources, and better established relationships with potential customers than we have. Many of our competitors have more resources and more experience in developing or acquiring new products and technologies, and in creating market awareness for those products and technologies. In addition, many of our competitors have the financial resources to offer competitive products at aggressive pricing levels that could prevent us from competing effectively. Further, many of our competitors have built long-standing relationships with some of our prospective and existing customers, and have the ability to provide financing to customers and could, therefore, have an inherent advantage in selling products to those customers.

Sales and Marketing

We market and sell our products and related support services primarily through our direct sales force, supported by marketing and product management personnel. We also use distribution or support partners to enter new markets or when requested by a potential customer. Our sales team has significant previous experience with the buying process and sales cycles typical of high-value telecommunications products.

The sales process for our products entails discussions with prospective customers, analyzing their networks and identifying how they can utilize our systems capabilities within their networks. This process requires developing strong customer relationships and leveraging our sales force and customer support capabilities to do so.

Over the course of the sales cycle, potential customers often test our products before buying. Prior to commercial deployment, the customer will generally perform a field trial of our products. Upon successful completion, the customer generally accepts the products installed in its network and may continue with commercial deployment of additional products. We anticipate that our sales cycle, from initial contact with a prospective customer through the signing of a purchase agreement may, in some cases, take several quarters.

Direct Sales Force. Our sales team sells directly to service providers worldwide. We maintain a sales presence throughout the United States, as well as in a number of international locations, including Argentina, Denmark, France, Germany, Hong Kong, India, Italy, Japan, Malaysia, Mexico, Netherlands, Poland, Russia, Singapore, Spain, Sweden and the United Kingdom. Adding incremental sales headcount in the future is expected to be success-based and in support of new customer accounts or expansion of existing ones.

Indirect Sales Force. We employ business consultants and resale and logistics partners to assist in our sales efforts, primarily in new regions for us whereby these partners have deep knowledge of typical business practices and strong relationships with key local operators. We expect to work with business partners to assist our customers in the sale, deployment and maintenance of our systems and have entered into distribution and resale agreements to facilitate the sale and support of our products.

Marketing and Product Management. Our product management team is responsible for defining the product features and go-to-market plan required to maximize our success in the marketplace. Product management supports our sales efforts with product and application expertise. Our corporate marketing team works to create demand for our products by communicating our value proposition and differentiation through direct customer interaction, public relations, attendance at tradeshows and other events, as well as internet programs and other marketing channels.

Research and Development

Continued investment in research and development is critical to our business. To this end, we have assembled a team of engineers with expertise in various fields, including systems, sub-systems, software and components. Our research and development efforts are currently focused in Sunnyvale, California; Allentown, Pennsylvania; Bangalore, India; Kanata, Canada; and Stockholm, Sweden. We utilize a mix of internal resources and supplement our staffing with development personnel provided by third parties on a contract basis. We have invested significant time and financial resources into the enhancement of existing products and the development of new products. We will continue to expand our product offerings and the capabilities of existing products in the future and plan to dedicate significant resources to these continued research and development efforts. We are continually increasing the scalability and software features of our current platforms. We are also working to develop new generations of optical engines at a faster cadence than we have historically in order to bring new products to market faster and meet customer demand. We believe these efforts will enhance our competitiveness in the markets we currently serve and also allow us to address adjacent markets to fuel our future growth.

Our research and development expenses were $224.3 million, $232.3 million and $180.7 million in 2017, 2016 and 2015, respectively.

Employees

As of December 30, 2017, we had 2,145 employees. A total of 1,003 of those employees were located outside of the United States. None of our U.S. employees are subject to a collective bargaining agreement. Employees in certain foreign jurisdictions may be represented by local workers’ councils and/or collective bargaining agreements, as may be customary or required in those jurisdictions. We have not experienced any work stoppages, and we consider our employee relationships to be good.

Manufacturing

We have invested significant time and capital to develop and improve the manufacturing processes we use to produce and package our products. This includes significant investments in personnel, equipment and the facilities needed to manufacture and package our products in Sunnyvale, California and Allentown, Pennsylvania. We also have invested in automating our manufacturing process and in training and maintaining the quality of our manufacturing workforce. As a leader in the development of photonic integration, our manufacturing processes have been developed over several years and are protected through a combination of trade secrets, patents and contractual protections. We believe that the investments we have made towards the manufacturing and packaging of our products provide us with a significant competitive advantage. We also believe that our current manufacturing facilities, including our fabrication facility for our PICs in Sunnyvale, California, and our module manufacturing facility in Allentown, Pennsylvania can accommodate an increase in production capacity as our business continues to grow.

We also use contract manufacturers to assemble portions of our products. Each contract manufacturer procures components necessary to assemble products according to our specifications and bills of material. For elements of our business where we outsource, we perform rigorous in-house quality control testing to ensure the reliability of our products. Our supply chain risk mitigation strategies are continuous and institutionalized in our supply chain design for external manufacturing and for procurement of components. We currently use four contract manufacturers in six different countries, China, Malaysia, Mexico, Sweden, Hungary and Thailand, as well as the capability to redirect manufacturing to U.S. qualified factories of three electronic manufacturing services partners.

We expect all suppliers to comply with our Supplier Code of Conduct, which addresses the rights of workers to safe and healthy working conditions, environmental responsibility and compliance with applicable laws.

Backlog

As of December 30, 2017 and December 31, 2016, our total order backlog was approximately $100.9 million and $74.0 million, respectively. Our backlog represents purchase orders received from customers for future product shipments and services. Our backlog is subject to future events that could cause the amount or timing of the related revenue to change, and, in certain cases, may be canceled without penalty. Orders in backlog may be fulfilled several quarters following receipt or may relate to multi-year support service obligations. As a result, we believe that backlog should not be viewed as an accurate indicator of future operating results for any particular period. A backlogged order may not result in revenue in a particular period, and the actual revenue may not be equal to our backlog amounts. Our presentation of backlog may not be comparable with that of other companies in our industry.

Intellectual Property

We believe our success depends upon our ability to protect our core technology and intellectual property. To accomplish this, we rely on a combination of intellectual property rights, including patents, trade secrets, copyrights and trademarks, as well as customary contractual protections.

Our optical engine technology, including our PIC, DSP, module and related technologies, are protected through a combination of patents, trade secrets and contractual protections. However, there can be no assurances that these protections will be sufficient to provide us with a competitive advantage or that others have not or will not reverse engineer our designs or discover, develop or disclose the same or similar designs and manufacturing processes.

As of December 30, 2017, we held 430 U.S. patents and 123 international patents expiring between 2021 and 2037, and held 122 U.S. and 21 foreign pending patent applications. We do not know whether any of our pending patent applications will result in the issuance of patents or whether the examination process will require us to narrow our claims.

We may not receive any competitive advantages from the rights granted under our patents and other intellectual property. Any patents granted to us may be contested, circumvented or invalidated over the course of our business, and we may not be able to prevent third parties from infringing these patents. Therefore, the impact of these patents cannot be predicted with certainty.

We believe that the frequency of assertions of patent infringement is increasing as patent holders, including entities that are not in our industry and who purchase patents as an investment or to monetize such rights by obtaining royalties, use such actions as a competitive tactic as well as a source of additional revenue. For example, we are currently involved in litigation for alleged patent infringement. See Item 3. “Legal Proceedings” for additional information regarding this lawsuit. Any claim of infringement from a third party, even those without merit, could cause us to incur substantial costs defending against such claims, and could distract our management from running our business. Furthermore, a party making such a claim, if successful, could secure a judgment that requires us to pay substantial damages or could include an injunction or other court order that could prevent us from offering our products. In addition, we might be required to seek a license for the use of such intellectual property, which may not be available on commercially reasonable terms or at all. Alternatively, we may be required to develop non-infringing technology, which would require significant effort and expense and may ultimately not be successful.

In addition to trade secret and patent protections, we generally control access to and the use of our proprietary software and other confidential information. This protection is accomplished through a combination of internal and external controls, including contractual protections with employees, contractors, customers and partners, and through a combination of U.S. and international copyright laws.

We license some of our software pursuant to agreements that impose restrictions on our customers’ ability to use such software, such as prohibiting reverse engineering and limiting the use of copies. We also seek to avoid disclosure of our intellectual property by relying on non-disclosure and assignment of intellectual property agreements with our employees and consultants that acknowledge our exclusive ownership of all intellectual property developed by the individual during the course of his or her work with us. The agreements also require that each person maintain the confidentiality of all proprietary information disclosed to them. Other parties may not comply with the terms of their agreements with us, and we may not be able to enforce our rights adequately against these parties. We also rely on contractual rights to establish and protect our proprietary rights in our products.

license terms and conditions could subject us to potential liability, including intellectual property infringement and or contractual claims. In such event, we could be required to seek licenses from third parties in order to continue offering our products, to re-engineer our products or to discontinue the sale of our products in the event re-engineering cannot be accomplished in a timely manner, any of which could adversely affect our business, operating results and financial condition.

Environmental Matters

We are committed to maintaining compliance with all environmental laws and regulations applicable to our operations, products and services. Our business and operations are subject to various federal, state, local and foreign laws and regulations that have been adopted with respect to the environment, including the Waste Electrical and Electronic Equipment (“WEEE”) Directive, Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (“RoHS”), and Registration, Evaluation, Authorization, and Restriction of Chemicals (“REACH”) regulations adopted by the European Union. Environmental regulation is increasing and we expect that our operations will be subject to additional environmental compliance requirements, which may expose us to additional costs. We are also subject to disclosure requirements related to the presence of "conflict minerals" in our products. To date, our compliance costs relating to environmental regulations have not resulted in a material adverse effect on our business, results of operations or financial condition.

ITEM 1A. RISK FACTORS

Investing in our securities involves a high degree of risk. Set forth below and elsewhere in this Annual Report on Form 10-K, and in other documents we file with the SEC, are risks and uncertainties that could cause our actual results to differ materially from the results contemplated by the forward-looking statements contained in this Annual Report on Form 10-K. Because of the following factors, as well as other variables affecting our operating results, past financial performance should not be considered as a reliable indicator of future performance and investors should not use historical trends to anticipate results or trends in future periods. If any of such risks and uncertainties actually occurs, our business, financial condition or operating results could differ materially from the plans, projections and other forward-looking statements included in the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in this Annual Report on Form 10-K and in our other public filings.

Our quarterly results may vary significantly from period to period, which could make our future results difficult to predict and could cause our operating results to fall below investor or analyst expectations.

Our quarterly results, in particular, our revenue, gross margins, operating expenses, operating margins and net income (loss), have historically varied from period to period and may continue to do so in the future. As a result, comparing our operating results on a period-to-period basis may not be meaningful. Our budgeted expense levels are based, in large part, on our expectations of future revenue and the development efforts associated with that future revenue. Consequently, if our revenue does not meet projected levels in the short-term, our inventory levels, cost of goods sold and operating expenses would be high relative to revenue, resulting in potential operating losses. For example, in each quarter of fiscal year 2017, we had operating losses, largely as a result of lower revenue and gross margins.

Factors that may contribute to fluctuations in our quarterly results, many of which are outside our control and may be difficult to predict, include:


•	fluctuations in demand, sales cycles and prices for products and services, including discounts given in response to competitive pricing pressures, as well as the timing of purchases by our key customers;


•	changes in customers’ budgets for optical transport network equipment purchases and changes or variability in their purchasing cycles;


•	fluctuations in our customer, product or geographic mix, including the impact of new customer deployments, which typically carry lower gross margins, and customer consolidation, which may affect our ability to grow revenue;


•	the timing and acceptance of our new product releases and our competitors' new product releases;


•	how quickly, or whether, the markets in which we operate adopt our solutions;


•	our ability to successfully restructure our operations within our anticipated timeframe and realize our anticipated savings;


•	order cancellations, reductions or delays in delivery schedules by our customers;


•	our ability to control costs, including our operating expenses and the costs and availability of components we purchase for our products;


•	our ability to increase volumes and yields on products manufactured in our internal manufacturing facilities;


•	any significant changes in the competitive dynamics of the markets we serve, including any new entrants, new technologies, or customer or competitor consolidation;


•	readiness of customer sites for installation of our products as well as the availability of third party suppliers to provide contract engineering and installation services for us;


•	the timing of recognizing revenue in any given quarter, including the impact of revenue recognition standards and any future changes in U.S. generally accepted accounting principles (“U.S. GAAP”) or new interpretations of existing accounting rules;


•	the impact of a significant natural disaster, such as an earthquake, severe weather, or tsunami or other flooding, as well as interruptions or shortages in the supply of utilities such as water and

electricity, in a key location such as our Northern California facilities, which is located near major earthquake fault lines and in a designated flood zone; and


•	general economic conditions in domestic and international markets.

Many factors affecting our results of operations are beyond our control and make it difficult to predict our results for a particular quarter and beyond. If our revenue or operating results do not meet the expectations of investors or securities analysts or fall below any guidance we provide to the market, the price of our common stock may decline substantially.

Any delays in the development and introduction of our new products or in releasing enhancements to our existing products may harm our business.

Because our products are based on complex technologies, including, in many cases, the development of next-generation PICs and specialized ASICs (key components of our optical engines), we may experience unanticipated delays in developing, improving, manufacturing or deploying these products. The development process for our optical engines is lengthy, and any modifications entail significant development cost and risks.

At any given time, various new product introductions and enhancements to our existing products are in the development phase and are not yet ready for commercial manufacturing or deployment. We rely on third parties, some of which are relatively early stage companies, to develop, manufacture and timely deliver components for our next-generation products, which can often require custom development. The development process from laboratory prototype to customer trials, and subsequently to general availability, involves a significant number of simultaneous efforts. These efforts often must be completed in a timely and coordinated manner so that they may be incorporated into the product development cycle for our systems, and include:


•	completion of product development, including the development and completion of our next-generation optical engines, and the completion of associated module development;


•	the qualification and multiple sourcing of critical components;


•	validation of manufacturing methods and processes;


•	extensive quality assurance and reliability testing and staffing of testing infrastructure;


•	validation of software; and


•	establishment of systems integration and systems test validation requirements.

Each of these steps, in turn, presents risks of failure, rework or delay, any one of which could decrease the speed and scope of product introduction and marketplace acceptance of our products. New generations of our optical engines as well as intensive software testing are important to the timely introduction of new products and enhancements to our existing products, and are subject to these development risks. In addition, unexpected intellectual property disputes, failure of critical design elements, limited or constrained engineering resources, and a host of other development execution risks may delay, or even prevent, the introduction of new products or enhancements to our existing products. If we do not develop and successfully introduce or enhance products in a timely manner, our competitive position will suffer.

As we transition to our next-generation products, we face significant risk that our new products may not be accepted by our current customers or by new customers. To the extent that we fail to introduce new and innovative products that are adopted by customers, we could fail to obtain an adequate return on these investments and could lose market share to our competitors, which could be difficult or impossible to regain. Similarly, we may face decreased revenue, gross margins and profitability due to a rapid decline in sales of current products as customers hold spending to focus purchases on new product platforms. We could incur significant costs in completing the transition, including costs of inventory write-downs of the current product as customers transition to new product platforms. In addition, products or technologies developed by others may render our products noncompetitive or obsolete and result in significant reduction in orders from our customers and the loss of existing and prospective customers.

Increased consolidation among our customers in the communications networking industry has and could continue to adversely affect our business and results of operations.

We have seen increased consolidation in the communications networking industry over the past few years, which has adversely affected our business and results of operations. For example, during 2016, Charter Communications completed its acquisition of Time Warner Cable, Inc. and Altice completed its acquisition of Cablevision, and during the first quarter of 2017, Verizon completed its acquisition of XO Communications. In addition, in November 2017, CenturyLink completed its acquisition of Level 3 Communications. Customer consolidation has led to changes in buying patterns, slowdowns in spending, redeployment of existing equipment and re-architecture of parts of an existing network or future networks, as the combined companies evaluate the needs of the combined business. Moreover, the significant purchasing power of these large companies can increase pricing and competitive pressures for us, including the potential for decreases in our average selling prices. If one of our customers is acquired by another company that does not rely on us to provide it with products or relies on another provider of similar products, we may lose that customer’s business. Such consolidation may further reduce the number of customers that generate a significant percentage of our revenue and may exacerbate the risks relating to dependence on a small number of customers. Any of the foregoing results will adversely affect our business, financial condition and results of operations.

Our ability to increase our revenue will depend upon continued growth of demand by consumers and businesses for additional network capacity and on the level and timing of capital spending by our customers.

Our future success depends on factors that increase the amount of data transmitted over communications networks and the growth of optical transport networks to meet the increased demand for optical capacity. These factors include the growth of mobile, video and cloud-based services, increased broadband connectivity and the continuing adoption of high-capacity, revenue-generating services. If demand for such bandwidth does not continue, or slows down, the market for optical transport networking equipment may not continue to grow and our product sales would be negatively impacted.

In addition, demand for our products depends on the level and timing of capital spending in optical networks by service providers as they construct, expand and upgrade the capacity of their optical networks. Capital spending is cyclical in our industry and spending by customers can change on short notice. Any future decisions by our customers to reduce capital spending, whether caused by lower customer demand or weakening economic conditions, changes in government regulations relating to telecommunications and data networks, customer consolidation or other reasons, could have a material adverse effect on our business, results of operations and financial condition.

Actions that we are taking to restructure our business to cut costs to align our operating structure with current opportunities may not be as effective as anticipated.

In November 2017, we implemented a plan to restructure our worldwide operations (the “2017 Restructuring Plan”) in order to reduce expenses and establish a more cost-effective structure that better aligns our operations with our long-term strategies. As part of the 2017 Restructuring Plan, we hope to reduce expenses, streamline the organization, and reallocate resources to align more closely with our needs going forward. While we expect to realize efficiencies from these actions, these activities might not produce the full efficiency and cost reduction benefits we expect. Further, such benefits may be realized later than expected, and the ongoing costs of implementing these measures may be greater than anticipated. In addition, as a result of the restructuring, our ability to execute on product development, address key market opportunities and/or meet customer demand, could be materially and adversely affected.

We are dependent on a small number of key customers for a significant portion of our revenue from period to period and the loss of, or a significant reduction in, orders from one or more of our key customers would reduce our revenue and harm our operating results.

A relatively small number of customers account for a large percentage of our revenue from period to period. For example, for fiscal year 2017, our top five customers accounted for approximately 44% of our total revenue. Included in these five customers is one customer that completed a merger in late 2017, which was a combination of two of our historically larger customers. For fiscal year 2016, our top five customers accounted for approximately 46% of our total revenue. Our business will likely be harmed if any of our key customers are acquired, do not generate as much revenue as we forecast, stop purchasing from us, delay anticipated product purchases, or substantially reduce their orders to us. In addition, our business will be harmed if we fail to maintain our competitive advantage with our key customers or do not add new larger customers over time. We continue to expect a relatively small number of customers to continue to account for a large percentage of revenue from period to period. However, customer consolidation could reduce the number of key customers that generate a significant percentage of our revenue and may increase the risks relating to dependence on a small number of customers.

Our ability to continue to generate revenue from our key customers will depend on our ability to maintain strong relationships with these customers and introduce competitive new products at competitive prices, and we may not be successful at doing so. In most cases, our sales are made to these customers pursuant to standard purchase agreements rather than long-term purchase commitments, and orders may be canceled or reduced readily. In the event of a cancellation or reduction of an order, we may not have enough time to reduce operating expenses to minimize the effect of the lost revenue on our business. Our operating results will continue to depend on our ability to sell our products to our key customers.

Our gross margin may fluctuate from period to period and may be adversely affected by a number of factors, some of which are beyond our control.

Our gross margin fluctuates from period to period and varies by customer and by product. Over the past eight fiscal quarters, our gross margin has ranged from 24.1% to 47.8%. Our gross margin is likely to continue to fluctuate and will be affected by a number of factors, including:


•	the mix of the types of customers purchasing our products as well as the product mix;


•	the timing of deploying solutions powered by our next generation technologies, which generate lower margin initially, as per unit production costs for initial units tend to be higher and experience more variability in production yields;


•	the pace at which we deploy solutions powered by our next generation technologies, which could lead to higher excess or obsolete inventory;


•	significant new deployments to existing and new customers, often with a higher portion of lower margin common equipment as we deploy network footprint;


•	changes in our manufacturing costs, including fluctuations in yields and production volumes;


•	pricing and commercial terms designed to secure long-term customer relationships, as well as commercial deals to transition certain customers to our new products;


•	the volume of Infinera Instant Bandwidth-enabled solutions sold, and capacity licenses activated;


•	price discounts negotiated by our customers;


•	charges for excess or obsolete inventory;


•	changes in the price or availability of components for our products; and


•	changes in warranty related costs.

It is likely that the average unit prices of our products will decrease over time in response to competitive pricing pressures. In addition, some of our customer contracts contain clauses that require us to annually decrease the sales price of our products to these customers. In response, we will need to reduce the cost of our products through manufacturing efficiencies, design improvements and cost reductions from our supply partners. If these efforts are not successful or if we are unable to reduce our costs by more than the reduction in the price

of our products, our gross margin will decline, causing our operating results to decline. Fluctuations in gross margin may make it difficult to manage our business and achieve or maintain profitability.

Aggressive business tactics by our competitors may harm our business.

The markets in which we compete are extremely competitive and this often results in aggressive business tactics by our competitors, including:


•	aggressively pricing their optical transport products and other portfolio products, including offering significant one-time discounts and guaranteed future price decreases;


•	offering optical products at a substantial discount or for free when bundled together with broader technology purchases, such as router or wireless equipment purchases;


•	providing financing, marketing and advertising assistance to customers; and


•	influencing customer requirements to emphasize different product capabilities, which better suit their products.

The level of competition and pricing pressure tend to increase when competing for larger high-profile opportunities or during periods of economic weakness when there are fewer network build-out projects. If we fail to compete successfully against our current and future competitors, or if our current or future competitors continue or expand their aggressive business tactics, including those described above, demand for our products could decline, we could experience delays or cancellations of customer orders, and/or we could be required to reduce our prices to compete in the market.

If we lose key personnel or fail to attract and retain additional qualified personnel when needed, our business may be harmed.

Our success depends to a significant degree upon the continued contributions of our key management, engineering, sales and marketing, and finance personnel, many of whom would be difficult to replace. For example, senior members of our engineering team have unique technical experience that would be difficult to replace. We do not have long-term employment contracts or key person life insurance covering any of our key personnel. Because our products are complex, we must hire and retain highly trained customer service and support personnel to ensure that the deployment of our products does not result in network disruption for our customers. We believe our future success will depend in large part upon our ability to identify, attract and retain highly skilled personnel. Competition for these individuals is intense in our industry, especially in the San Francisco Bay Area where we are headquartered. We may not succeed in identifying, attracting and retaining appropriate personnel. The loss of the services of any of our key personnel, the inability to identify, attract or retain qualified personnel in the future or delays in hiring qualified personnel, particularly engineers and sales personnel, could make it difficult for us to manage our business and meet key objectives, such as timely product introductions.

The markets in which we compete are highly competitive and we may not be able to compete effectively.

Competition in the optical transport networking equipment market is intense. Our main competitors include WDM system suppliers, such as Adva, Ciena, Cisco, Coriant, Fujitsu, Huawei, Nokia and ZTE. In addition, there are several smaller but established companies that offer one or more products that compete with our offerings.

Competition in the markets we serve is based on any one or a combination of the following factors:


•	price and other commercial terms;


•	functionality;


•	existing business and customer relationships;


•	the ability of products and services to meet customers’ immediate and future network requirements;


•	power consumption;


•	heat dissipation;


•	form factor or density;


•	installation and operational simplicity;


•	service and support;


•	security and encryption requirements;


•	scalability and investment protection; and


•	product lead times.

In addition to our current competitors, other companies have, or may in the future develop, products that are or could be competitive with our products. We also could encounter competitor consolidation in the markets in which we compete, which could lead to a changing competitive landscape, capabilities and market share, and could impact our results of operations.

Some of our competitors have substantially greater name recognition, technical, financial and marketing resources, and better established relationships with potential customers than we have. Many of our competitors have more resources and more experience in developing or acquiring new products and technologies, and in creating market awareness for those products and technologies. In addition, many of our competitors have the financial resources to offer competitive products at aggressive pricing levels that could prevent us from competing effectively. Further, many of our competitors have built long-standing relationships with some of our prospective and existing customers and have the ability to provide financing to customers and could, therefore, have an inherent advantage in selling products to those customers.

We also compete with low-cost producers that can increase pricing pressure on us and a number of smaller companies that provide competition for a specific product, customer segment or geographic market. In addition, we may also face increased competition from system and component companies that develop products based on off-the-shelf hardware that offers the latest commercially available technologies. Due to the narrower focus of their efforts, these competitors may achieve commercial availability of their products more quickly than we can and may provide attractive alternatives to our customers.

We must respond to rapid technological change and comply with evolving industry standards and requirements for our products to be successful.

The optical transport networking equipment market is characterized by rapid technological change, changes in customer requirements and evolving industry standards. We continually invest in research and development to sustain or enhance our existing products, but the introduction of new communications technologies and the emergence of new industry standards or requirements could render our products obsolete. Further, in developing our products, we have made, and will continue to make, assumptions with respect to which standards or requirements will be adopted by our customers and competitors. If the standards or requirements adopted by our prospective customers are different from those on which we have focused our efforts, market acceptance of our products would be reduced or delayed and our business would be harmed.

We are continuing to invest a significant portion of our research and development efforts in the development of our next-generation products. We expect our competitors will continue to improve the performance of their existing products and introduce new products and technologies and to influence customers’ buying criteria so as to emphasize product capabilities that we do not, or may not, possess. To be competitive, we must anticipate future customer requirements and continue to invest significant resources in research and development, sales and marketing, and customer support. If we do not anticipate these future customer requirements and invest in the technologies necessary to enable us to have and to sell the appropriate solutions, it may limit our competitive position and future sales, which would have an adverse effect on our business and financial condition. We may not have sufficient resources to make these investments and we may not be able to make the technological advances necessary to be competitive.

The manufacturing process for our PICs is very complex and the partial or complete loss of our manufacturing facilities, or a reduction in yields or an inability to scale capacity to meet customer demands could harm our business.

The manufacturing process for our PICs and certain components of our products is very complex. In the event that any of the manufacturing facilities utilized to build these components were fully or partially destroyed, as a result of fire, water damage, or otherwise, it would limit our ability to produce our products. Because of the complex nature of our manufacturing facilities, such loss would take a considerable amount of time to repair or rebuild. The partial or complete loss of any of our manufacturing facilities, or an event causing the interruption in our use of such facility for any extended period of time would cause our business, financial condition and operating results to be harmed.

Minor deviations in the PIC manufacturing process can cause substantial decreases in yields and, in some cases, cause production to be suspended. In the past, we have had significant variances in our PIC yields, including production interruptions and suspensions and may have continued yield variances, including additional interruptions or suspensions in the future. Lower than expected yields from our PIC manufacturing process or defects, integration issues or other performance problems in our products could limit our ability to satisfy customer demand requirements, and could damage customer relations and cause business reputation problems, harming our business and operating results.

Our inability to obtain sufficient manufacturing capacity to meet demand, either in our own facilities or through foundry or similar arrangements with third parties, could harm our relationships with our customers, our business and our operating results.

Our large customers have substantial negotiating leverage, which may cause us to agree to terms and conditions that result in decreased revenue due to lower average selling prices and potentially increased cost of sales leading to lower gross margin, all of which would harm our operating results.

Many of our customers are large service providers that have substantial purchasing power and leverage in negotiating contractual arrangements with us. In addition, customer consolidation in the past few years has created combined companies that are even larger and have greater negotiating leverage. Our customers have and may continue to seek advantageous pricing, payment and other commercial terms. We have and may continue to agree to unfavorable commercial terms with these customers, including the potential of reducing the average selling price of our products, increasing cost of sales or agreeing to extended payment terms in response to these commercial requirements or competitive pricing pressures. To maintain acceptable operating results, we will need to comply with these commercial terms, develop and introduce new products and product enhancements on a timely basis, and continue to reduce our costs.

We are dependent on sole source and limited source suppliers for several key components, and if we fail to obtain these components on a timely basis, we will not meet our customers’ product delivery requirements.

We currently purchase several key components for our products from sole or limited sources. In particular, we rely on our own production of certain components of our products, such as PICs, and on third parties, including sole source and limited source suppliers, for certain of the components of our products, including ASICs, field-programmable gate arrays, processors, and other semiconductor and optical components. We have increased our reliance on third parties to develop and manufacture components for certain products, some of which require custom development. We purchase most of these components on a purchase order basis and only have long-term contracts with these sole source or limited source suppliers. If any of our sole source or limited source suppliers suffer from capacity constraints, lower than expected yields, deployment delays, work stoppages or any other reduction or disruption in output, they may be unable to meet our delivery schedule which could result in lost revenue, additional product costs and deployment delays that could harm our business and customer relationships. Further, our suppliers could enter into exclusive arrangements with our competitors, refuse to sell their products or components to us at commercially reasonable prices or at all, go out of business or discontinue their relationships with us. We may be unable to develop alternative sources for these components.

The loss of a source of supply, or lack of sufficient availability of key components, could require us to redesign products that use such components, which could result in lost revenue, additional product costs and deployment delays that could harm our business and customer relationships. In addition, if our contract

manufacturers do not receive critical components in a timely manner to build our products, then we would not be able to ship in a timely manner and would, therefore, be unable to meet our prospective customers’ product delivery requirements. In the past, we have experienced delivery delays because of lack of availability of components or reliability issues with components that we were purchasing. In addition, some of our suppliers have gone out of business, merged with another supplier, or limited their supply of components to us, which may cause us to experience longer than normal lead times, supply delays and increased prices. We may in the future experience a shortage of certain components as a result of our own manufacturing issues, manufacturing issues at our suppliers or contract manufacturers, capacity problems experienced by our suppliers or contract manufacturers, strong demand in the industry for such components, or other disruptions in our supply chain. In addition, global macroeconomic conditions are likely to continue to create pressure on us and our suppliers to accurately project overall component demand and manufacturing capacity. These supplier disruptions may continue to occur in the future, which could limit our ability to produce our products and cause us to fail to meet a customer’s delivery requirements. Any failure to meet our customers’ product delivery requirements could harm our reputation and our customer relationships, either of which would harm our business and operating results.

If we fail to accurately forecast our manufacturing requirements or customer demand, we could incur additional costs, including inventory write-downs or equipment write-offs, which would adversely affect our business and results of operations.

We generate forecasts of future demand for our products several months prior to the scheduled delivery to our prospective customers. This requires us to make significant investments before we know if corresponding revenue will be recognized. Lead times for materials and components, including ASICs, that we need to order for the manufacture of our products vary significantly and depend on factors such as the specific supplier, contract terms and demand for each component at a given time. In the past, we have experienced lengthening in lead times for certain components. If the lead times for components are lengthened, we may be required to purchase increased levels of such components to satisfy our delivery commitments to our customers. In addition, we must manage our inventory to ensure we continue to meet our commitments as we introduce new products or make enhancements to our existing products.

If we overestimate market demand for our products and, as a result, increase our inventory in anticipation of customer orders that do not materialize, we will have excess inventory, which could result in increased risk of obsolescence and significant inventory write-downs. Furthermore, this will result in reduced production volumes and our fixed costs will be spread across fewer units, increasing our per unit costs. If we underestimate demand for our products, we will have inadequate inventory, which could slow down or interrupt the manufacturing of our products and result in delays in shipments and our ability to recognize revenue. In addition, we may be unable to meet our supply commitments to customers, which could result in a loss of certain customer opportunities or a breach of our customer agreements resulting in payment of damages.

If our contract manufacturers do not perform as we expect, our business may be harmed.

We rely on third party contract manufacturers to perform a portion of the manufacturing of our products, and our future success will depend on our ability to have sufficient volumes of our products manufactured in a cost-effective and quality-controlled manner. We have engaged third parties to manufacture certain elements of our products at multiple contract manufacturing sites located around the world but do not have long-term agreements in place with some of our manufacturers and suppliers that will guarantee product availability, or the continuation of particular pricing or payment terms. There are a number of risks associated with our dependence on contract manufacturers, including:


•	reduced control over delivery schedules, particularly for international contract manufacturing sites;


•	reliance on the quality assurance procedures of third parties;


•	potential uncertainty regarding manufacturing yields and costs;


•	potential lack of adequate capacity during periods of high demand;


•	limited warranties on components;


•	potential misappropriation of our intellectual property; and


•	potential manufacturing disruptions (including disruptions caused by geopolitical events, military actions or natural disasters).

Any of these risks could impair our ability to fulfill orders. Any delays by our contract manufacturers may cause us to be unable to meet the delivery requirements of our customers, which could decrease customer satisfaction and harm our product sales. In addition, if our contract manufacturers are unable or unwilling to continue manufacturing our products or components of our products in required volumes or our relationship with any of our contract manufacturers is discontinued for any reason, we would be required to identify and qualify alternative manufacturers, which could cause us to be unable to meet our supply requirements to our customers and result in the breach of our customer agreements. Qualifying a new contract manufacturer and commencing volume production is expensive and time-consuming and if we are required to change or qualify a new contract manufacturer, we could lose revenue and damage our customer relationships.

Our sales cycle can be long and unpredictable, which could result in an unexpected revenue shortfall in any given quarter.

Our products can have a lengthy sales cycle, which can extend from six to twelve months and may take even longer for larger prospective customers. Our prospective customers conduct significant evaluation, testing, implementation and acceptance procedures before they purchase our products. We incur substantial sales and marketing expenses and expend significant management effort during this time, regardless of whether we make a sale.

Because the purchase of our equipment involves substantial cost, most of our customers wait to purchase our equipment until they are ready to deploy it in their network. As a result, it is difficult for us to accurately predict the timing of future purchases by our customers. In addition, product purchases are often subject to budget constraints, multiple approvals and unplanned administrative processing and other delays. If sales expected from customers for a particular quarter are not realized in that quarter or at all, our revenue will be negatively impacted.

Product performance problems, including undetected errors in our hardware or software, or deployment delays could harm our business and reputation.

The development and production of products with high technology content is complicated and often involves problems with software, components and manufacturing methods. Complex hardware and software systems, such as our products, can often contain undetected errors when first introduced or as new versions are released. In addition, errors associated with components we purchase from third parties, including customized components, may be difficult to resolve. We have experienced issues in the past in connection with our products, including failures due to the receipt of faulty components from our suppliers. In addition, performance issues can be heightened during periods where we are developing and introducing multiple new products to the market, as any performance issues we encounter in one technology or product could impact the performance or timing of delivery of other products. Our products may suffer degradation of performance and reliability over time.

If reliability, quality or network monitoring problems develop, a number of negative effects on our business could result, including:


•	reduced orders from existing customers;


•	declining interest from potential customers;


•	delays in our ability to recognize revenue or in collecting accounts receivables;


•	costs associated with fixing hardware or software defects or replacing products;


•	high service and warranty expenses;


•	delays in shipments;


•	high inventory excess and obsolescence expense;


•	high levels of product returns;


•	diversion of our engineering personnel from our product development efforts; and


•	payment of liquidated damages, performance guarantees or similar penalties.

Because we outsource the manufacturing of certain components of our products, we may also be subject to product performance problems as a result of the acts or omissions of third parties.

From time to time, we encounter interruptions or delays in the activation of our products at a customer’s site. These interruptions or delays may result from product performance problems or from issues with installation and activation, some of which are outside our control. If we experience significant interruptions or delays that we cannot promptly resolve, the associated revenue for these installations may be delayed or confidence in our products could be undermined, which could cause us to lose customers and fail to add new customers.

If we need additional capital in the future, it may not be available to us on favorable terms, or at all.

Our business requires significant capital. We have historically relied on outside debt or equity financing as well as cash flow from operations to fund our operations, capital expenditures and expansion. We may require additional capital from equity or debt financings in the future to fund our operations, respond to competitive pressures or strategic opportunities or to refinance our existing debt obligations. In the event that we require additional capital, we may not be able to secure timely additional financing on favorable terms, or at all. The terms of any additional financing may place limits on our financial and operating flexibility. If we raise additional funds through further issuances of equity, convertible debt securities or other securities convertible into equity, our existing stockholders could suffer dilution in their percentage ownership of our company, and any new securities we issue could have rights, preferences and privileges senior to those of holders of our common stock. If we are unable to obtain adequate financing or financing on terms satisfactory to us, if and when we require it, our ability to grow or support our business and to respond to business challenges could be limited and our business will be harmed.

Our debt obligations may adversely affect our ability to raise additional capital and will be a burden on our future cash resources, particularly upon settlement of any conversions of the Notes or upon maturity or required repurchase of the Notes.

In May 2013, we issued the $150.0 million of 1.75% convertible senior notes due June 1, 2018 (the “Notes”), which will mature on June 1, 2018. The degree to which we are leveraged could have important consequences, including, but not limited to, the following:


•	our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, litigation, general corporate or other purposes may be limited; and


•	a substantial portion of our future cash balance may be dedicated to the payment of the principal of our indebtedness as we have stated the intention to pay the principal amount of the Notes in cash upon conversion or when otherwise due, such that we would not have those funds available for use in our business.

Our ability to meet our payment obligations under our debt instruments, including the Notes, which mature on June 1, 2018 and require cash to be paid upon conversion, maturity or required repurchase thereof, depends on our future cash flow performance. This, to some extent, is subject to general economic, financial, competitive, legislative and regulatory factors, as well as other factors that may be beyond our control. There can be no assurance that our business will generate positive cash flow from operations, or that additional capital will be available to us, in an amount sufficient to enable us to meet our debt payment obligations and to fund other liquidity needs. If we are unable to generate sufficient cash flow to service our debt obligations, we may need to refinance or restructure our debt, sell assets, reduce or delay capital investments, or seek to raise additional capital. If we were unable to implement one or more of these alternatives, we may be unable to meet our debt payment obligations. As a result, we may be more vulnerable to economic downturns, less able to withstand competitive pressures and less flexible in responding to changing business and economic conditions.

The fundamental change provisions of the Notes may delay or prevent an otherwise beneficial takeover attempt of us.

If a fundamental change, such as an acquisition of our company, occurs prior to the maturity of the Notes, holders of the Notes will have the right, at their option, to require us to repurchase all or a portion of their Notes. In addition, if such fundamental change also constitutes a make-whole fundamental change, the conversion rate for the Notes may be increased upon conversion of the Notes in connection with such make-whole fundamental change. Any increase in the conversion rate will be determined based on the date on which the make-whole fundamental change occurs or becomes effective and the price paid (or deemed paid) per share of our common stock in such transaction. Our obligation to repurchase Notes or increase the conversion rate upon the occurrence of a make-whole fundamental change may, in certain circumstances, delay or prevent a takeover of us that might otherwise be beneficial to our stockholders.

Changes in accounting principles may cause previously unanticipated fluctuations in our financial results, and the implementation of such changes may impact our ability to meet our financial reporting obligations.

We prepare our financial statements in accordance with U.S. GAAP, which are subject to interpretation or changes by the Financial Accounting Standards Board (the “FASB”), the SEC, and other various bodies formed to promulgate and interpret appropriate accounting principles. New accounting pronouncements and changes in accounting principles have occurred in the past and are expected to occur in the future, which may have a significant effect on our financial results. For example, in May 2014, the FASB issued Accounting Standards Update 2014-09, “Revenue from Contracts from Customers (Topic 606),” which supersedes most current revenue recognition guidance, including industry-specific guidance. We will be required to implement this new revenue standard for our fiscal year beginning December 31, 2017. Please see Note 2, “Recent Accounting Pronouncements” to the Notes to Consolidated Financial Statements for more information. We are continuing to evaluate the effect that the new standard will have on our consolidated financial statements and our preliminary assessments remain subject to change. Any difficulties in implementation of changes in accounting principles, including the ability to modify our accounting systems, could cause us to fail to meet our financial reporting obligations, which could result in regulatory discipline and damage our reputation with investors.

If we fail to protect our intellectual property rights, our competitive position could be harmed or we could incur significant expense to enforce our rights.

We depend on our ability to protect our proprietary technology. We rely on a combination of methods to protect our intellectual property, including limiting access to certain information, and utilizing trade secret, patent, copyright and trademark laws and confidentiality agreements with employees and third parties, all of which offer only limited protection. The steps we have taken to protect our proprietary rights may be inadequate to preclude misappropriation or unauthorized disclosure of our proprietary information or infringement of our intellectual property rights, and our ability to police such misappropriation, unauthorized disclosure or infringement is uncertain, particularly in countries outside of the United States. This is likely to become an increasingly important issue if we expand our operations and product development into countries that provide a lower level of intellectual property protection. We do not know whether any of our pending patent applications will result in the issuance of patents or whether the examination process will require us to narrow our claims, and even if patents are issued, they may be contested, circumvented or invalidated. Moreover, the rights granted under any issued patents may not provide us with a competitive advantage, and, as with any technology, competitors may be able to develop similar or superior technologies to our own now or in the future.

Protecting against the unauthorized use of our products, trademarks and other proprietary rights is expensive, difficult, time consuming and, in some cases, impossible. Litigation may be necessary in the future to enforce or defend our intellectual property rights, to protect our trade secrets or to determine the validity or scope of the proprietary rights of others. Such litigation could result in substantial cost and diversion of management resources, either of which could harm our business, financial condition and operating results. Furthermore, many of our current and potential competitors have the ability to dedicate substantially greater resources to enforce their intellectual property rights than we do. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or misappropriating our intellectual property.

Claims by others that we infringe their intellectual property could harm our business.

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. In particular, many leading companies in the optical transport networking industry, including our competitors, have extensive patent portfolios with respect to optical transport networking technology. In addition, patent holding companies seek to monetize patents they have purchased or otherwise obtained. We expect that infringement claims may increase as the number of products and competitors in our market increases and overlaps occur. From time to time, third parties may assert exclusive patent, copyright, trademark and other intellectual property rights to technologies and related standards that are important to our business or seek to invalidate the proprietary rights that we hold. Competitors or other third parties have, and may continue to assert claims or initiate litigation or other proceedings against us or our manufacturers, suppliers or customers alleging infringement of their proprietary rights, or seeking to invalidate our proprietary rights, with respect to our products and technology. In addition, we have had certain patent licenses with third parties that have not been renewed, and if we cannot successfully renew these licenses, we could face claims of infringement. In the event that we are unsuccessful in defending against any such claims, or any resulting lawsuit or proceedings, we could incur liability for damages and/or have valuable proprietary rights invalidated. For additional information regarding certain of the legal proceedings in which we are involved, see Item 3, "Legal Proceedings," contained in Part I of this report.

Any claim of infringement from a third party, even one without merit, could cause us to incur substantial costs defending against the claim, and could distract our management from running our business. Furthermore, a party making such a claim, if successful, could secure a judgment that requires us to pay substantial damages or could include an injunction or other court order that could prevent us from offering our products. In addition, we might be required to seek a license for the use of such intellectual property, which may not be available on commercially reasonable terms or at all. Alternatively, we may be required to develop non-infringing technology, which would require significant effort and expense and may ultimately not be successful. Any of these events could harm our business, financial condition and operating results. Competitors and other third parties have and may continue to assert infringement claims against our customers and sales partners. Any of these claims would require us to initiate or defend potentially protracted and costly litigation on their behalf, regardless of the merits of these claims, because we generally indemnify our customers and sales partners from claims of infringement of proprietary rights of third parties. If any of these claims succeed, we may be forced to pay damages on behalf of our customers or sales partners, which could have an adverse effect on our business, financial condition and operating results.

We may also be required to indemnify some customers under our contracts if a third party alleges, or a court finds, that our products have infringed upon the proprietary rights of other parties. From time to time, we have agreed to indemnify certain customers for claims made against our products, where such claims allege infringement of third party intellectual property rights, including, but not limited to, patents, registered trademarks and/or copyrights. If we are required to make a significant payment under any of our indemnification obligations, our result of operations may be harmed.

We incorporate free and open source licensed software into our products. Although we monitor our use of such open source software closely, the terms of many open source licenses have not been interpreted by U.S. courts, and there is a risk that such licenses could be construed in a manner that could impose unanticipated conditions or restrictions on our ability to commercialize our products. In addition, non-compliance with open source software license terms and conditions could subject us to potential liability, including intellectual property infringement and/or contract claims. In such events, we may be required to seek licenses from third parties in order to continue offering our products, to re-engineer our products or to discontinue the sale of our products in the event re-engineering cannot be accomplished in a timely manner, any of which could adversely affect our business, operating results and financial condition.

The trading price of our common stock has been volatile and is likely to be volatile in the future.

The trading prices of our common stock and the securities of other technology companies have been and may continue to be highly volatile. Factors affecting the trading price of our common stock include:


•	variations in our operating results;


•	changes in the estimates of our future operating results or external guidance on those results or changes in recommendations or business expectations by any securities analysts that elect to follow our common stock;


•	announcements of technological innovations, new services or service enhancements, the gain or loss of customers, strategic alliances or agreements by us or by our competitors;


•	market conditions in our industry, the industries of our customers and the economy as a whole;


•	mergers and acquisitions by us, by our competitors or by our customers;


•	recruitment or departure of key personnel; and


•	adoption or modification of regulations, policies, procedures or programs applicable to our business.

In addition, if the market for technology stocks or the broader stock market experience a loss of investor confidence, the trading price of our common stock could decline for reasons unrelated to our business, financial condition or operating results. The trading price of our common stock might also decline in reaction to events that affect other companies in our industry even if these events do not directly affect us. Each of these factors, among others, could harm the value of your investment in our common stock. Some companies that have had volatile market prices for their securities have had securities class action lawsuits filed against them. If a suit were filed against us, regardless of its merits or outcome, it could result in substantial costs and divert management’s attention and resources.

Unfavorable macroeconomic and market conditions may adversely affect our industry, business and financial results.

Our business depends on the overall demand for additional bandwidth capacity and on the economic health and willingness of our customers and potential customers to make capital commitments to purchase our products and services. As a result of macroeconomic or market uncertainty, we may face new risks that we have not yet identified. In addition, a number of the risks associated with our business, which are disclosed in these risk factors, may increase in likelihood, magnitude or duration.

In the past, unfavorable macroeconomic and market conditions have resulted in sustained periods of decreased demand for optical communications products. These conditions may also result in the tightening of credit markets, which may limit or delay our customers’ ability to obtain necessary financing for their purchases of our products. A lack of liquidity in the capital markets or the continued uncertainty in the global economic environment may cause our customers to delay or cancel their purchases, increase the time they take to pay or default on their payment obligations, each of which would negatively affect our business and operating results. Weakness and uncertainty in the global economy could cause some of our customers to become illiquid, delay payments or adversely affect our collection of their accounts, which could result in a higher level of bad debt expense. In addition, currency fluctuations could negatively affect our international customers’ ability or desire to purchase our products.

Challenging economic conditions have from time to time contributed to slowdowns in the telecommunications industry in which we operate. Such slowdowns may result in:


•	reduced demand for our products as a result of constraints on capital spending by our customers;


•	increased price competition for our products, not only from our competitors, but also as a result of our customer’s or potential customer’s utilization of inventoried or underutilized products, which could put additional downward pressure on our near term gross profits;


•	risk of excess or obsolete inventories;


•	excess manufacturing capacity and higher associated overhead costs as a percentage of revenue; and


•	more limited ability to accurately forecast our business and future financial performance.

A lack of liquidity and economic uncertainty may adversely affect our suppliers or the terms on which we purchase products from these suppliers. It may also cause some of our suppliers to become illiquid. Any of these impacts could limit our ability to obtain components for our products from these suppliers and could adversely impact our supply chain or the delivery schedule to our customers. This also could require us to purchase more expensive components, or re-design our products, which could cause increases in the cost of our products and delays in the manufacturing and delivery of our products. Such events could harm our gross margin and harm our reputation and our customer relationships, either of which could harm our business and operating results.

Our international sales and operations subject us to additional risks that may harm our operating results.

Sales of our products into international markets are an important part of our business. During fiscal year 2017, fiscal year 2016 and fiscal year 2015, we derived approximately 42%, 38% and 32%, respectively, of our revenue from customers outside of the United States. We expect that significant management attention and financial resources will be required for our international activities over the foreseeable future as we continue to operate in international markets. In some countries, our success in selling our products and growing revenue will depend in part on our ability to form relationships with local partners. Our inability to identify appropriate partners or reach mutually satisfactory arrangements for international sales of our products could impact our ability to maintain or increase international market demand for our products. In addition, many of the companies we compete against internationally have greater name recognition and a more substantial sales and marketing presence.

We have sales and support personnel in numerous countries worldwide. In addition, we have established development centers in Canada, India and Sweden. There is no assurance that our reliance upon development resources in international locations will enable us to achieve meaningful cost reductions or greater resource efficiency.

Our international operations are subject to inherent risks, and our future results could be adversely affected by a variety of factors, many of which are outside of our control, including:


•	greater difficulty in collecting accounts receivable and longer collection periods;


•	difficulties of managing and staffing international offices, and the increased travel, infrastructure and legal compliance costs associated with multiple international locations;


•	political, social and economic instability, including wars, terrorism, political unrest, boycotts, curtailment of trade and other business restrictions;


•	tariff and trade barriers and other regulatory requirements or contractual limitations on our ability to sell or develop our products in certain foreign markets;


•	less effective protection of intellectual property than is afforded to us in the United States or other developed countries;


•	local laws and practices that favor local companies, including business practices that we are prohibited from engaging in by the Foreign Corrupt Practices Act and other anti-corruption laws and regulations;


•	potentially adverse tax consequences; and


•	effects of changes in currency exchange rates, particularly relative increases in the exchange rate of the U.S. dollar versus other currencies that could negatively affect our financial results and cash flows.

International customers may also require that we comply with certain testing or customization of our products to conform to local standards. The product development costs to test or customize our products could be extensive and a material expense for us.

Our international operations are subject to increasingly complex foreign and U.S. laws and regulations, including but not limited to anti-corruption laws, such as the Foreign Corrupt Practices Act and the UK Bribery Act and equivalent laws in other jurisdictions, antitrust or competition laws, and data privacy laws, among others. Violations of these laws and regulations could result in fines and penalties, criminal sanctions against us, our officers, or our employees, prohibitions on the conduct of our business and on our ability to offer our products and services in one or more countries, and could also materially affect our reputation, our international expansion efforts, our ability to attract and retain employees, our business, and our operating results. Although we have implemented policies, procedures and training designed to ensure compliance with these laws and regulations, there can be no complete assurance that any individual employee, contractor or agent will not violate our policies. Additionally, the costs of complying with these laws (including the costs of investigations, auditing and monitoring) could also adversely affect our current or future business.

As we continue to expand our business globally, our success will depend, in large part, on our ability to effectively anticipate and manage these and other risks and expenses associated with our international operations. For example, political instability and uncertainty in the European Union and, in particular, the United Kingdom's pending exit from the E.U. (Brexit) as well as other countries potentially choosing to exit the E.U., could slow economic growth in the region, affect foreign exchange rates, and could further discourage near-term economic activity, including our customers delaying purchases of our products. Our failure to manage any of these risks successfully could harm our international operations and reduce our international sales, and business generally, adversely affecting our business, operating results and financial condition.

We may be adversely affected by fluctuations in currency exchange rates.

A portion of our sales and expenses stem from countries outside of the United States, and are in currencies other than U.S. dollars, and therefore subject to foreign currency fluctuation. Accordingly, fluctuations in foreign currency rates could have a material impact on our financial results in future periods. We may enter into other financial contracts to reduce the impact of foreign currency fluctuations. We currently enter into foreign currency exchange forward contracts to reduce the impact of foreign currency fluctuations on accounts receivable, and also to reduce the volatility of cash flows primarily related to forecasted foreign currency revenue and expenses. These forward contracts reduce the impact of currency exchange rate movements on certain transactions, but do not cover all foreign-denominated transactions and therefore do not entirely eliminate the impact of fluctuations in exchange rates that could negatively affect our results of operations and financial condition.

Our effective tax rate may increase or fluctuate, which could increase our income tax expense and reduce our net income.

Our effective tax rate can be adversely affected by several factors, many of which are outside of our control, including:


•	changes in the valuation of our deferred tax assets and liabilities, and in deferred tax valuation allowances;


•	changes in the relative proportions of revenue and income before taxes in the various jurisdictions in which we operate that have differing statutory tax rates;


•	changing tax laws, regulations, rates and interpretations in multiple jurisdictions in which we operate;


•	changes in accounting and tax treatment of equity-based compensation;


•	changes to the financial accounting rules for income taxes; and


•	the resolution of issues arising from tax audits.

The international tax environment continues to change as a result of both coordinated actions by governments and unilateral measures designed by individual countries, both intended to tackle concerns over base erosion and profit shifting (“BEPS”) and perceived international tax avoidance techniques. The recommendations of the BEPS Project led by the Organization for Economic Cooperation and Development are involved in much of the coordinated activity, although the timing and methods of implementation vary. In addition, on December 22, 2017, the U.S. Tax Cuts and Jobs Act (the “Tax Act”) was signed into law, which significantly revises the U.S. corporate income tax regime by, among other things, lowering corporate income tax rate from 35% to 21% effective January 1, 2018, imposing a repatriation tax on deemed repatriated earnings of our foreign subsidiaries in 2017, and implementing a quasi-territorial tax system on future foreign earnings. Such changes in tax laws or their interpretation could adversely affect our effective tax rates and our results.

If we fail to maintain effective internal control over financial reporting in the future, the accuracy and timing of our financial reporting may be adversely affected.

We are required to comply with Section 404 of the Sarbanes-Oxley Act of 2002. The provisions of the act require, among other things, that we maintain effective internal control over financial reporting and disclosure controls and procedures. Preparing our financial statements involves a number of complex processes, many of which are done manually and are dependent upon individual data input or review. These processes include, but are not limited to, calculating revenue, deferred revenue and inventory costs. While we continue to automate our processes and enhance our review and put in place controls to reduce the likelihood for errors, we expect that for the foreseeable future, many of our processes will remain manually intensive and thus subject to human error.

Any acquisitions we make could disrupt our business and harm our financial condition and operations.

We may make strategic acquisitions of businesses, technologies and other assets. If we are not able to achieve the anticipated strategic benefits of such acquisitions, it could adversely affect our business, financial condition and results of operations. In addition, the market price of our common stock could be adversely affected if the integration or the anticipated financial and strategic benefits of such acquisitions are not realized as rapidly as, or to the extent anticipated by investors and securities analysts.

The expansion of our business through acquisitions allows us to complement our technological capabilities and address new markets. In the event of any future acquisitions, we may not ultimately strengthen our competitive position or achieve our goals, or they may be viewed negatively by customers, financial markets or investors and we could:


•	issue stock that would dilute our current stockholders’ percentage ownership;


•	incur debt and assume other liabilities;


•	use a substantial portion of our cash resources; or


•	incur amortization expenses related to other intangible assets and/or incur large and write-offs.

Acquisitions can result in adverse tax consequences, warranty or product liability exposure related to acquired assets, additional stock-based compensation expense, and write-up of acquired inventory to fair value. In addition, we may record goodwill and other purchased intangible assets in connection with an acquisition and incur impairment charges in the future. If our actual results, or the plans and estimates used in future impairment analyses, are less favorable than the original estimates used to assess the recoverability of these assets, we could incur additional impairment charges.

Acquisitions also involve numerous risks that could disrupt our ongoing business and distract our management team, including:


•	problems integrating the acquired operations, technologies or products with our own;


•	diversion of management’s attention from our core business;


•	adverse impact on overall company operating results;


•	adverse effects on existing business relationships with suppliers and customers;


•	risks associated with entering new markets; and


•	loss of key employees.

Our failure to adequately manage the risks associated with an acquisition could have an adverse effect on our business, financial condition and operating results.

Unforeseen health, safety and environmental costs could harm our business.

Our manufacturing operations use substances that are regulated by various federal, state and international laws governing health, safety and the environment, including the Waste Electrical and Electronic Equipment Directive, Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment, and the Registration, Evaluation, Authorization, and Restriction of Chemicals regulations adopted by the European Union. If we experience a problem with complying with these regulations, it could cause an interruption or delay in our manufacturing operations or could cause us to incur liabilities for any costs related to health, safety or environmental remediation. We could also be subject to liability if we do not handle

these substances in compliance with safety standards for storage and transportation and applicable laws. If we experience a problem or fail to comply with such safety standards, our business, financial condition and operating results may be harmed.

We are subject to governmental regulations that could adversely affect our business.

We are subject to U.S. and foreign trade control laws that may limit where and to whom we sell our products. These trade control laws also limit our ability to conduct product development activities in certain countries and restrict the handling of our U.S. export controlled technology. In addition, various countries regulate the import of certain technologies and have enacted laws that could limit our ability to distribute our products and certain product features or could limit our customers’ ability to implement our products in those countries. Changes in our products or changes in U.S. and foreign import and export regulations may create delays in the introduction of our products in international markets, prevent our customers with international operations from deploying our products throughout their global systems or, in some cases, prevent the import and export of our products to certain countries altogether. Any change in import and export regulations or related legislation, shift in approach to the enforcement or scope of existing regulations, or change in the countries, persons or technologies impacted by such regulations, could result in decreased use of our products by, or in our decreased ability to export or sell our products to, existing or potential customers with international operations. Failure to comply with these and similar laws on a timely basis, or at all, decreased use of our products or any limitation on our ability to develop, export or sell our products would adversely affect our business, financial condition and operating results.

Our product or manufacturing standards could also be impacted by new or revised environmental rules and regulations or other social initiatives. For instance, the SEC adopted new disclosure requirements in 2012 relating to the sourcing of certain minerals from the Democratic Republic of Congo and certain other adjoining countries. Those rules, which required reporting for the first time in calendar 2014, could adversely affect our costs, the availability of minerals used in our products and our relationships with customers and suppliers.

The Federal Communications Commission (“FCC”) has jurisdiction over the entire U.S. communications industry and, as a result, our products and our U.S. customers are subject to FCC rules and regulations. Current and future FCC regulations, including regulations on net neutrality or generally affecting communications services, our products or our customers’ businesses could negatively affect our business. In addition, international regulatory standards could impair our ability to develop products for international customers in the future. Moreover, many jurisdictions are evaluating or implementing regulations relating to cybersecurity, privacy and data protection, which can affect the market and requirements for networking and communications equipment. For example, in April 2016, the European Parliament approved the General Data Protection Regulation (the “GDPR”), which will come into effect in May 2018 and supersede current EU data protection regulations. The GDPR will impose stringent data handling requirements on companies that receive or process personal data of residents of the EU, and non-compliance with the GDPR could result in significant penalties, including data protection audits and heavy fines. Any failure to obtain the required approvals or comply with such laws and regulations could harm our business and operating results.

Natural disasters, terrorist attacks or other catastrophic events could harm our operations.

Our headquarters and the majority of our infrastructure, including our PIC fabrication manufacturing facility, are located in Northern California, an area that is susceptible to earthquakes, floods and other natural disasters. Further, a terrorist attack aimed at Northern California or at the United States energy or telecommunications infrastructure could hinder or delay the development and sale of our products. In the event that an earthquake, terrorist attack or other man-made or natural catastrophe were to destroy any part of our facilities, or certain of our contract manufacturers’ facilities, destroy or disrupt vital infrastructure systems or interrupt our operations for any extended period of time, our business, financial condition and operating results would be harmed.

Security incidents, such as data breaches and cyber-attacks, could compromise our intellectual property and proprietary or confidential information and cause significant damage to our business and reputation.

In the ordinary course of our business, we maintain sensitive data on our networks, including data related to our intellectual property and data related to our business, customers and business partners, which is considered proprietary or confidential information. We believe that companies in the technology industry have been increasingly subject to a wide variety of security incidents, cyber-attacks and other attempts to gain unauthorized access. While the secure maintenance of this information is critical to our business and reputation, our network and storage applications may be subject to unauthorized access by hackers or breached due to operator error, malfeasance or other system disruptions. It may be difficult to anticipate or immediately detect such security incidents or data breaches and the damage caused as a result. Accordingly, a data breach, cyber-attack, or unauthorized access or disclosure of our information, could compromise our intellectual property and reveal proprietary or confidential business information. In addition, these security incidents could also cause us to incur significant remediation costs and expenses, disrupt key business operations, subject us to liability and divert attention of management and key information technology resources, any of which could cause significant harm to our business and reputation.

Anti-takeover provisions in our charter documents and Delaware law could discourage, delay or prevent a change in control of our company and may affect the trading price of our common stock.

We are a Delaware corporation and the anti-takeover provisions of the Delaware General Corporation Law, which apply to us, may discourage, delay or prevent a change in control by prohibiting us from engaging in a business combination with an interested stockholder for a period of three years after the person becomes an interested stockholder, even if a change of control would be beneficial to our existing stockholders. In addition, our amended and restated certificate of incorporation and amended and restated bylaws may discourage, delay or prevent a change in our management or control over us that stockholders may consider favorable. Our amended and restated certificate of incorporation and amended and restated bylaws:


•	authorize the issuance of “blank check” convertible preferred stock that could be issued by our board of directors to thwart a takeover attempt;


•	establish a classified board of directors, as a result of which the successors to the directors whose terms have expired will be elected to serve from the time of election and qualification until the third annual meeting following their election;


•	require that directors only be removed from office for cause and only upon a supermajority stockholder vote;


•	provide that vacancies on the board of directors, including newly-created directorships, may be filled only by a majority vote of directors then in office rather than by stockholders;


•	prevent stockholders from calling special meetings; and


•	prohibit stockholder action by written consent, requiring all actions to be taken at a meeting of the stockholders.

Included above are certain facilities located in Sunnyvale, CA, Carrollton, TX and Stockholm, Sweden, which we have vacated as part of this restructuring. See Note 8, "Restructuring and Other Related Costs," to the Notes to Consolidated Financial Statements for more information on the 2017 Restructuring Plan.

In May 2017, we purchased a 60,000 square-foot module manufacturing facility and the associated land that we had previously leased in Allentown, Pennsylvania. We believe that our existing facilities are adequate to meet our business needs through the next 12 months, and that suitable additional or substitute space will be available as needed to accommodate any expansion of our operations.

ITEM 3. LEGAL PROCEEDINGS

On November 23, 2016, Oyster Optics, LLC (“Oyster Optics”) filed a complaint against us in the United States District Court for the Eastern District of Texas. The complaint asserts U.S. Patent Nos. 6,469,816, 6,476,952, 6,594,055, 7,099,592, 7,620,327, 8,374,511 and 8,913,898 (collectively, the “Oyster Optics patents in suit”). The complaint seeks unspecified damages and a permanent injunction. We believe that we do not infringe any valid and enforceable claim of the Oyster Optics patents in suit, and intend to defend this action vigorously. We filed our answer to Oyster Optics' complaint on February 3, 2017. On October 23, 2017, we filed a petition for Inter Partes Review (“IPR”) of one of the Oyster Optics patents in suit, U.S. Patent No. 8,913,898 (the “'898 patent”), with the U.S. Patent and Trademark Office, and, on December 1, 2017, we filed a second petition for IPR of the '898 patent. Other defendants have filed IPR petitions in connection with the Oyster Optics patents in suit. The Court has set a trial for June 2018. We are currently unable to predict the outcome of this litigation and therefore cannot reasonably estimate the possible loss or range of loss, if any, arising from this matter.

On March 24, 2017, Core Optical Technologies, LLC (“Core Optical”) filed a complaint against us in the United States District Court for the Central District of California. The complaint asserts U.S. Patent No. 6,782,211 (the “Core Optical patent in suit”). The complaint seeks unspecified damages and a permanent injunction. We believe that we do not infringe any valid and enforceable claim of the Core Optical patent in suit, and intend to defend this action vigorously. We filed our answer to Core Optical's complaint on September 25, 2017. Because this action is in the early stages, we are unable to predict the outcome of this litigation at this time and therefore cannot reasonably estimate the possible loss or range of loss, if any, arising from this matter.

In addition to the matters described above, we are subject to various legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not

determinable, we do not expect that the ultimate costs to resolve these matters will have a material effect on our consolidated financial position, results of operations or cash flows.

The following discussion and analysis should be read in conjunction with our “Selected Financial Data” included in Item 6 of this Annual Report on Form 10-K and consolidated financial statements and notes thereto included elsewhere in this Annual Report on Form 10-K.

Overview

We are a leader in optical transport networking solutions, providing equipment, software and services to telecommunications service providers, ICPs, cable providers, wholesale and enterprise carriers, research and education institutions, enterprise customers, and government entities across the globe. Optical transport networks are deployed by customers facing significant demand for optical bandwidth prompted by increased use of high-speed internet access, business Ethernet services, mobile broadband, cloud-based services, high-definition video streaming services, virtual and augmented reality, and the Internet of Things (IoT).

Our optical transport systems are highly scalable, flexible and open, built using a combination of internally manufactured and third-party components. Technologically, a key element of our systems are optical engines, which comprise large-scale PICs and DSPs. We optimize the manufacturing process by using indium phosphide to build our PICs, which enables the integration of a large amount of optical functions onto a set of semiconductor chips. This large scale integration of our PICs and advanced DSPs allow us to deliver on features that customers care about the most, including cost per bit, power and space. In addition, our optical engines are designed to increase the capacity and reach performance of our products leveraging coherent optical transmission.

Over the past few years, we have significantly increased the number of products we offer, evolving from focusing entirely on the long-haul and subsea markets to offering a more complete portfolio of solutions that span the long-haul, subsea, DCI and metro markets. In late 2014, we expanded our addressable market by introducing the Cloud Xpress platform for the DCI market to meet a growing need for metro-reach optical interconnections between data centers. We introduced the Cloud Xpress 2 in mid-2017, which further optimizes capacity, space and power, all key elements our ICP customers value.

In the second half of 2015, we entered the metro market with the acquisition of Transmode, a leader in metro packet-optical applications, based in Stockholm, Sweden. Entering into the metro market expanded our addressable market and enabled us to offer a more complete portfolio of solutions, particularly to existing long-haul customers that also build metro networks. We have expanded our suite of metro solutions by both

enhancing our XTM Series platforms but also utilizing our optical engines to deliver Cloud Xpress, XT and XTC Series platforms.

In 2017, we began shipping two new platforms based on our new generation technology. First, we introduced a series of new products powered by the Infinite Capacity Engine (ICE), a technology which delivers multi-terabit opto-electronic subsystems powered by our fourth-generation PIC and next-generation FlexCoherent DSP (the combination of which we refer to as “ICE4”). The Infinite Capacity Engine enables different subsystems that can be customized for a variety of network applications across our product portfolio, spanning the long-haul, subsea, DCI and metro markets. Second, we released our next-generation XTM Series platform, which leverages 16QAM modulation technology and is optimized for bandwidth-intensive applications at the metro edge.

2017 Financial and Business Performance

Total revenue was $740.7 million in 2017 as compared to $870.1 million in 2016. This decrease was due to a combination of factors that included customer consolidation, transition to our next-generation products and shifts in network spend, including weak overall market spending for long-haul solutions. In the second half of 2017, business began to gradually recover as we started shipping our first ICE4 products. This product upgrade helped our DCI business as ICPs demonstrated interest in our upgraded Cloud Xpress and XT platforms, and also in subsea, a technically demanding market, where ICE4 products showed early traction based on advances in spectral efficiency. During 2017, we continued to expand our installed base in the metro market as we made progress selling the XTM platform to both traditional long-haul customers as well as our new customers. Gross margin decreased to 32.9% in 2017 from 45.2% in 2016. The decline in gross margin was primarily attributable to making strategic investments, amidst our product transition, to secure future business with existing and prospective customers across our end markets and the high cost of early production units from our ICE4 products that started to ship during the second half of the year. In addition, as our revenue declined, we continued to maintain consistent levels of manufacturing and services staffing, thus requiring us to absorb those fixed costs of a smaller revenue base, which put pressure on gross margin over the year.

Exiting a challenging 2017, we expect revenue will grow in 2018. Growth will be largely dependent on completing our new product introductions, continued customer adoption of our new products, our ability to expand our number of customers and addressable revenue opportunities, and the recovery of spend with our major consolidated customers. It will also depend on overall market conditions. Our near-term quarter-over-quarter revenue could be volatile and impacted by the same factors, and also affected by customer buying patterns and the timing of customer network deployments.

In 2018, while difficult to predict margins on a quarterly basis, having made significant investments in 2017 and having endured a majority of the early high costs of production units associated with our product transition, we expect less overall variability in margins over the course of 2018. We expect a steady increase in gross margin levels as mix shifts to the next-generation products, as we increase volumes in the fab, and as we improve the yields on the next-generation products. We expect operating expenses in 2018 should be lower as a percentage of overall revenue compared to 2017, given the substantial investments we made in prior years to drive a faster technology cadence and deliver our next-generation products to market. In addition, we reduced our ongoing cost structure as part of the 2017 Restructuring Plan. See Note 8, “Restructuring and Other Related Costs,” to the Notes to Consolidated Financial Statements for more information on the 2017 Restructuring Plan.

Over a longer period of time, we believe that we can further leverage our vertically-integrated manufacturing model, which combined with a faster cadence of introducing new products, the ability to continue to sell incremental bandwidth capacity into deployed networks, and expense management, can result in improved profitability and cash flow.

One customer, which completed a merger in late 2017, was a combination of two of our historically

larger customers who merged in 2017 and accounted for approximately 18% of our revenue in 2017. These two historically larger customers each individually accounted for approximately 16% and 8% of our revenue in 2016, respectively, and approximately 17% and 13% of our revenue in 2015, respectively. No other customers accounted for over 10% of our revenue for these periods.

We primarily sell our products through our direct sales force, with a small portion sold indirectly through resellers. We derived 94%, 93% and 93% of our revenue from direct sales to customers for 2017, 2016 and 2015, respectively. We expect to continue generating a substantial majority of our revenue from direct sales in the future.

We are headquartered in Sunnyvale, California, with employees located throughout the Americas, Europe and the Asia Pacific region.

2017 Compared to 2016. Total revenue decreased by $129.4 million, or 15%, in 2017 from 2016, driven by significantly lower product sales over the course of 2017. Product revenue decreased by $140.6 million, or

19%, in 2017 from 2016, primarily attributable to effects of customer consolidation, impacts from our product transition as well as customers shifting spend to other parts of their networks.

Services revenue increased by $11.2 million, or 9%, in 2017 from 2016, primarily attributable to continued growth in on-going support services as a result of our growing installed base of customer networks.

2016 Compared to 2015. Product revenue decreased by $18.1 million, or 2%, in 2016 from 2015. We experienced a slowdown in spending from multiple key customers primarily due to the effects of significant consolidation amongst our customers during the second half of 2016. This decrease was partially offset by increased revenue due to the inclusion of a full year's worth of revenue from new metro products from the Transmode business, which was acquired on August 20, 2015.

Services revenue increased by $1.5 million, or 1%, in 2016 from 2015, primarily attributable to higher on-going support services as we grew our installed base over the course of 2016.

Looking ahead, we anticipate increased revenue from our next-generation products across our customer verticals and expect our cable vertical, in particular, to be strong in early 2018. We currently expect total revenue in the first quarter of 2018 will be slightly higher on a sequential basis compared to the prior quarter.

2017 Compared to 2016. Domestic revenue decreased by $113.3 million, or 21%, during 2017 compared to 2016, primarily attributable to the effects of customer consolidation, and changes in certain large customers’ buying patterns as we transition to our next-generation of products. The majority of the decrease in

2017 occurred in the first half of the year, as the revenue during the second half of the year was up by 8% as compared to the corresponding period in 2016, primarily driven by improved spending from cable customers.

International revenue decreased by $16.1 million, or 5%, during 2017 compared to 2016, primarily attributable to lower sales from our Other Americas region, where we continued to be challenged by slower spending from our largest customer in the region due to political conditions. We had a small decline in our Europe, Middle East and Africa (“EMEA”) region attributable to product transitions and a challenging pricing environment.

2016 Compared to 2015. Domestic revenue decreased by $60.5 million, or 10%, during 2016 compared to 2015, primarily driven by customers across multiple end markets slowing spend due to a variety of factors, including shifts of spending to other parts of customer networks, the build-up of inventory at customer sites, along with customer consolidation and competitive challenges in certain markets.

International revenue increased by $44.0 million, or 15%, during 2016 compared to 2015, primarily led by the EMEA region due to the inclusion of revenue from Transmode, which generates most of its revenue from the EMEA region.

Cost of Revenue and Gross Margin

2017 Compared to 2016. Gross margin decreased to 32.9% in 2017 from 45.2% in 2016. This decline was driven primarily by the high early manufacturing costs from initial units of our new ICE-based products, and with changes in customer mix and strategic investments to win and preserve business as we brought our new products to market. Lower overall manufacturing levels during 2017 compared to 2016 also reduced the benefits of our vertically-integrated operating model. Gross margin in 2017 was also impacted by restructuring and other related costs of $19.1 million, which consisted of $13.6 million of inventory write-downs and $4.0 million of manufacturing asset impairments as a result of our product rationalization efforts, and $1.5 million of employee-related costs for eliminated roles.

See Note 8, “Restructuring and Other Related Costs,” to the Notes to Consolidated Financial Statements for more information on the 2017 Restructuring Plan.

2016 Compared to 2015. Gross margin decreased to 45.2% in 2016 from 45.5% in 2015, primarily driven by the impact of reduced volumes on our manufacturing infrastructure. We also experienced downward pressure on gross margin throughout the year as we made strategic pricing decisions to secure future business with existing and prospective customers across our end markets. Additionally, 2015 included a full year of purchase accounting costs, primarily related to amortization of intangibles associated with the Transmode acquisition.

We currently expect that gross margin in the first quarter of 2018 will be higher than the fourth quarter of 2017 due to our expectation that restructuring-related costs in the first quarter will be much lower. In addition, we have substantially incurred the impact of the high costs of the early production units of ICE4 as well as additional costs to bridge customers to our new products.

As we seek to grow our footprint with both existing and new customers, we expect to deploy large amounts of network infrastructure, which initially carries low gross margins but establishes the groundwork for growth at higher gross margins. Over time as our new ICE-based products, which carry lower costs at increased volumes, grow as a percentage of our overall mix, our gross margins should gradually improve.

Research and Development Expenses

2017 Compared to 2016. Research and development expenses decreased by $8.0 million, or 3%, in 2017 from 2016, with the biggest driver being an $11.3 million impairment charge recorded in 2016, resulting from our decision to stop development on certain technologies that were in-process at the time of the Transmode acquisition. We also incurred lower spending in development and manufacturing expenses of $8.6 million, as we drove efficiencies in our development and manufacturing business over the course of the year. These decreases were offset by an increase of $10.9 million in personnel expenses. During the year, we balanced investments around bringing our next-generation solutions to market and enacting a faster technology development cadence, with prudent expense management, particularly given our overall revenue decrease.

2016 Compared to 2015. Research and development expenses increased by $51.6 million, or 29%, in 2016 from 2015 primarily due to increased personnel costs of $34.5 million as a result of incremental headcount primarily from the acquisition of Transmode and an $11.3 million impairment on acquired in-process technology related to Transmode. Additionally, we had increased spending on prototype and other engineering materials of $7.4 million, incremental outside professional services costs of $2.1 million and other engineering expenses of $1.0 million to support the development of our next generation of products. These increases were partially offset by a decrease in management bonuses of $4.7 million.

Sales and Marketing Expenses

2017 Compared to 2016. Sales and marketing expenses decreased by $2.8 million, or 2%, in 2017 from 2016 as we tightly managed expenses, such as outside professional services and travel during the year. In 2017, outside professional services declined by $1.6 million, and travel and entertainment declined by $1.1 million. Overall personnel costs were effectively flat in 2017.

2016 Compared to 2015. Sales and marketing expenses increased by $17.5 million, or 17%, in 2016 from 2015 primarily due to increased personnel costs of $14.5 million as a result of incremental headcount primarily from the acquisition of Transmode and to support the expansion of our business into new markets and customer verticals. In addition, the increase also included amortization of intangible assets of $3.9 million, higher professional services costs of $1.3 million and an increase in discretionary spending of $0.2 million. These increases were partially offset by a decrease in management bonuses of $2.4 million.

General and Administrative Expenses

2017 Compared to 2016. General and administrative expenses increased by $2.3 million, or 3%, in 2017 from 2016 primarily due to increased depreciation expenses of $1.6 million and personnel costs of $1.5 million. These expenses were offset by a $1.6 million decrease in travel, equipment and facilities, and lower consulting services of $0.5 million.

2016 Compared to 2015. General and administrative expenses increased by $6.7 million, or 11%, in 2016 from 2015 primarily due to increased personnel costs of $9.3 million as a result of incremental headcount from the acquisition of Transmode and to a lesser extent, to scale our infrastructure to support the business. In addition, during 2016, we incurred increased facilities and related costs of $1.3 million and higher depreciation expense of $1.2 million. These increases were partially offset by a decrease in management bonuses of $2.6 million and professional services costs of $2.5 million.

Restructuring and Other Related Costs

2017 Compared to 2016. In 2017, within operating expenses, we incurred $16.1 million in restructuring and other related costs, including $7.9 million of severance related costs, $7.3 million of facilities impairment costs and test equipment impairments of $0.9 million. We have implemented the majority of these actions with some remaining payments in the first half of 2018. See Note 8, “Restructuring and Other Related Costs,” to the Notes to Consolidated Financial Statements for more information on the 2017 Restructuring Plan.

2017 Compared to 2016. Interest income increased $0.8 million primarily due to a higher return on investments. Interest expense for 2017 increased $1.1 million due to an increase in amortization of discount and issuance costs related to the Notes. The change in other gain (loss), net, was primarily due to a $1.9 million

impairment charge on our cost-method investment in 2017 compared to a $9.0 million gain on the sale of a cost-method investment in 2016.

2016 Compared to 2015. Interest income increased $0.6 million primarily due to a higher return on investments. Interest expense for 2016 increased $0.9 million due to an increase of amortization of discount and issuance costs related to the Notes. The change in other gain (loss), net, during 2016 was primarily due to a $9.0 million gain on the sale of a cost-method investment, partially offset by losses due to foreign currency exchange. Other gain (loss), net, for 2015 mainly comprised of $1.3 million of gains due to foreign currency exchange rate changes and a $1.1 million gain primarily from foreign currency forward contracts that we entered into to hedge currency exposures associated with the cash portion of the offer to acquire Transmode.

Benefit From Income Taxes

On December 22, 2017, the Tax Act was signed into law. The Tax Act significantly revises the U.S. corporate income tax regime by, among other things, lowering corporate income tax rate from 35% to 21% effective January 1, 2018, while also imposing a repatriation tax on deemed repatriated earnings of our foreign subsidiaries in 2017, and implementing a quasi-territorial tax system on future foreign earnings.

We have calculated our best estimate of the impact of the Tax Act in our year-end income tax provision in accordance with our understanding of the Tax Act and guidance available as of the date of this filing. While the reduction of the federal corporate income tax rate from 35% to 21% requires the re-measurement of our net U.S. deferred tax assets, there is also a corresponding and equal adjustment to the associated valuation allowance, and therefore no net impact to our statements of operations in 2017. Additionally, due to net tax losses on an aggregate basis of our foreign subsidiaries, there is no repatriation tax accruable in 2017.

We currently estimate that the tax impact of the Tax Act to be fairly negligible in the near-term, while sufficient net operating loss carryforwards generated prior to the Tax Act are available to fully offset future taxable income. Notwithstanding this, the Tax Act also introduces a Base Erosion Anti-Abuse Tax (“BEAT”), which is a minimum tax potentially accruable on certain intercompany payments to our foreign subsidiaries. Uncertainty regarding these provisions remain and are subject to further technical guidance. However, we believe that any tax accruable for the BEAT will be nominal in the near-term, based upon our current estimates and our corporate structure.

We recognized an income tax benefit of $1.4 million on a loss before income taxes of $195.9 million, income tax benefit of $4.8 million on a loss before income taxes of $29.2 million, and income tax expense of $1.1 million on income before income taxes of $52.0 million in fiscal years 2017, 2016 and 2015, respectively. The resulting effective tax rates were (0.7)%, (16.3)% and 2.1% for 2017, 2016 and 2015, respectively. The 2017 and 2016 effective tax rates differ from the expected statutory rate of 35% based on our ability to benefit U.S. loss carryforwards, offset by state income taxes, non-deductible stock-based compensation expenses and foreign taxes provided on foreign subsidiary earnings. The lower 2017 income tax benefit compared to 2016 primarily relates to lower acquisition related amortization expenses and lower state income taxes offset by an increase in tax reserves, and an increase in taxable foreign profits in certain jurisdictions. The tax benefit for 2016 compared to tax expense in 2015 was primarily due to acquisition related amortization expenses and charges, lower state taxes, and a reduction in tax reserves, offset by an increase in taxable foreign profits.

Because of our U.S. operating loss in 2017, significant loss carryforward position, and corresponding full valuation allowance in all years, we have not been subject to federal or state tax on our U.S. income because of the availability of loss carryforwards, with the exception of amounts for certain states’ taxes for which the losses were limited by statute or amount in 2016 and more significantly in 2015, and federal and state taxes associated with a discontinued U.S. subsidiary. If these losses and other tax attributes become fully utilized, our taxes will increase significantly to a more normalized, expected rate on U.S. earnings. The release of transfer pricing reserves in the future will have a beneficial impact to tax expense, but the timing of the impact depends on factors such as expiration of the statute of limitations or settlements with tax authorities. No significant releases are expected in the near future based on information available at this time.

In determining future taxable income, we make assumptions to forecast federal, state and international operating income, the reversal of temporary differences, and the implementation of any feasible and prudent tax planning strategies. The assumptions require significant judgment regarding the forecasts of future taxable income, and are consistent with our income forecasts used to manage our business.

Operating Activities

Net cash used in operating activities was $21.9 million for 2017, as compared to net cash provided by operating activities of $38.4 million and $133.2 million for 2016 and 2015, respectively.

Net loss for 2017 was $194.5 million, which included non-cash charges of 154.9 million, compared to a net loss for 2016 of $24.4 million, which included non-cash charges of $116.3 million. Net income for 2015 was $51.0 million, which included non-cash charges of $80.1 million.

Net cash provided by working capital was $17.6 million for 2017. Accounts receivables decreased by $25.8 million attributable to lower revenue levels during 2017. Inventory levels decreased by $2.7 million reflecting inventory reduction and product rationalization efforts. Accounts payable decreased by $4.8 million primarily due to reduced inventory purchases and timing of payments. Accrued liabilities and other expenses decreased $14.4 million primarily due to reduced levels of compensation-related accruals and decreased accrued warranty primarily due to changes in estimated repair and replacement costs, along with improved failure rates. Deferred revenue increased $16.4 million attributable to commercial arrangements with customers to transition to new products and continued growth in on-going support services for our installed base, which are typically contracted on an annual or multi-year basis.

Net cash used in working capital was $53.5 million for 2016. Accounts receivables decreased by $33.9 million as our revenue levels decreased significantly during the second half of 2016. Inventory levels increased by $64.1 million as a result of stocking more components due to longer lead times with component suppliers, building up our PIC die bank inventory for our current generation of products to allow us to shift manufacturing capacity to our next generation PICs, building up new product inventory, as well as lower shipment volumes in recent periods. Accounts payable decreased by $28.3 million primarily due to lower business volume during

2016. Deferred revenue increased $21.4 million primarily due to higher ongoing support services as we continued to grow our installed base.

Net cash provided by working capital was $2.1 million for 2015. Accounts receivables increased by $16.0 million primarily due to the timing of invoicing in the period and inventory levels increased by $17.1 million to support the higher expected demand including multiple new products. Accounts payable increased by $19.2 million primarily reflecting the volume of the business and timing of payments during the period. Accrued warranty increased by $10.8 million due to general warranty reserves, the incremental cost to support the increased installed base and higher repair costs.

Investing Activities

Net cash used in investing activities for 2017 was $50.6 million, including $58.0 million of capital expenditures, of which $12.4 million was due to our purchase of our module manufacturing facility in Pennsylvania in May 2017. Partially offsetting those spend activities were net proceeds of $3.2 million associated with purchases, sales, maturities and calls of investments during the year.

Net cash used in investing activities for 2016 was $12.1 million, including $43.3 million of capital expenditures and $7.0 million invested in a cost-method investment. Partially offsetting those spend activities were proceeds from the sale of a cost-method investment of $23.5 million and net proceeds of $18.8 million associated with purchases and maturities of investments during the period.

Net cash used in investing activities for 2015 was $91.5 million, including the payment of $144.4 million in connection with the acquisition of Transmode and $42.0 million of capital expenditures. Partially offsetting those spend activities, we had net proceeds of $93.8 million associated with purchases, maturities and sales of investments during the year as we rearranged our portfolio to fund the acquisition and realized a $1.1 million gain from foreign currency exchange forward contracts.

Financing Activities

Net proceeds from financing activities were $22.1 million, $8.9 million and $21.0 million for 2017, 2016 and 2015, respectively. Financing activities in 2017 included $18.0 million in net proceeds from the issuance of shares under our 2007 Employee Stock Purchase Plan (“ESPP”) and the exercise of stock options. Proceeds were offset by the minimum tax withholdings paid on behalf of certain employees for net share settlements of restricted stock units. Additionally, during 2017, we received $5.6 million in cash released from the security pledge maintained during the period to acquire the remaining 4.2% of Transmode AB shares not tendered in the initial acquisition offer. In association with the compulsory acquisition proceedings in accordance with Swedish law, we paid $0.5 million to the minority shareholders of Transmode based on the final determination of the arbitration tribunal.

Financing activities in 2016 included $16.8 million related to the purchase of the noncontrolling interest upon award on advance title to acquire the remaining 4.2% of Transmode shares and $6.1 million associated with the security pledge related to the Transmode acquisition. Additionally, financing activities in 2016 included net proceeds from the exercise of stock options and the issuance of shares under our ESPP. These proceeds were offset by the minimum tax withholdings paid on behalf of certain employees for net share settlements of restricted stock units.

Financing activities in 2015 primarily included net proceeds from the exercise of stock options, purchase of shares under our ESSP. These proceeds were offset by the minimum tax withholdings paid on behalf of employees for net share settlements of restricted stock units. Financing activities in 2015 also included proceeds from the exercise of stock options.

Liquidity

We believe that our current cash, cash equivalents and investments will be sufficient to meet our anticipated cash needs for working capital and capital expenditures, including the costs associated with the 2017 Restructuring Plan, for at least the next 12 months. If these sources of cash are insufficient to satisfy our liquidity requirements beyond 12 months, we may require additional capital from equity or debt financings to fund our operations, to respond to competitive pressures or strategic opportunities, or otherwise. We may not be able to secure timely additional financing on favorable terms, or at all. The terms of any additional financings may place limits on our financial and operating flexibility. If we raise additional funds through further issuances of equity, convertible debt securities or other securities convertible into equity, our existing stockholders could suffer

dilution in their percentage ownership of us, and any new securities we issue could have rights, preferences and privileges senior to those of holders of our common stock.

In May 2013, we issued the Notes, which will mature on June 1, 2018, unless earlier purchased by us or converted. Interest is payable semi-annually in arrears on June 1 and December 1 of each year, commencing December 1, 2013. The net proceeds from the Notes issuance were approximately $144.5 million and to date, we have not utilized the net proceeds due to our sufficient cash position.

Due to the upcoming maturity of the Notes on June 1, 2018, the outstanding principal amount was reclassified from long-term debt to short-term debt in our consolidated balance sheets during the second quarter of 2017.

During the third quarter of 2017, the closing price of our common stock did not meet the stock price conversion trigger; therefore, holders of the Notes could not convert their Notes during the fourth quarter of 2017. The Notes became convertible at the option of the holders beginning on December 1, 2017 pursuant to the stock price conversion trigger. The Notes became convertible at the option of the holders beginning on December 1, 2017 and will be convertible until the close of business on the second scheduled trading day immediately preceding the maturity date.

Upon conversion, it is our intention to pay cash equal to the lesser of the aggregate principal amount or the conversion value of the Notes. For any remaining conversion obligation, we have made an election to settle in cash. For all conversions that occur on or after December 1, 2017, we have elected a cash settlement method. As of December 30, 2017, short-term debt, net, was $144.9 million, which represents the liability component of the $150.0 million principal balance, net of $5.1 million of unamortized debt discount and debt issuance costs. The debt discount and debt issuance costs are currently being amortized over the remaining term until maturity of the Notes on June 1, 2018.

As of December 30, 2017, the contractual obligation related to the Notes is $151.3 million, which is due in June 2018. This amount represents principal and interest cash payments over the term of the Notes. Any future redemption, conversion or refinancing of the Notes could impact the amount or timing of our cash payments. For more information regarding the Notes, see Note 11, “Convertible Senior Notes” to the Notes to Consolidated Financial Statements.

As of December 30, 2017, we had $263.9 million of cash, cash equivalents, and short-term investments, including $62.1 million of cash and cash equivalents held by our foreign subsidiaries. Prior to the enactment of the Tax Act, our policy with respect to undistributed foreign subsidiaries’ earnings was to consider those earnings to be indefinitely reinvested and therefore we have not accrued such withholding taxes. Under the Tax Act, undistributed earnings of foreign subsidiaries are deemed to be repatriated for U.S. corporate tax purposes and a one-time toll tax at a reduced U.S. corporate tax rate is applicable in 2017. However, because of the aggregated net tax loss of our foreign subsidiaries, no U.S. tax is accruable in 2017. If and when funds are actually distributed in the form of dividends or otherwise, foreign withholding taxes would be applicable in some jurisdictions, and in such jurisdictions we have no intent to repatriate these funds and therefore, have not accrued such withholding taxes.

⁽¹⁾	We have service agreements with our major production suppliers under which we are committed to purchase certain parts.

⁽²⁾

We lease facilities under non-cancelable operating lease agreements. These leases have varying terms that range from one to 10 years, and contain leasehold improvement incentives, rent holidays and escalation clauses. In addition, some of these leases have renewal options for up to five years. We also have contractual commitments to remove leasehold improvements and return certain properties to a specified condition when the leases terminate. At the inception of a lease with such conditions, we record an asset retirement obligation liability and a corresponding capital asset in an amount equal to the estimated fair value of the obligation. Leasehold improvements are amortized using the straight-line method over the shorter of the lease term or estimated useful life of the asset. An assumption of lease renewal where a renewal option exists is used only when the renewal has been determined to be reasonably assured. The estimated useful life of leasehold improvements is one to 10 years. See Note 12, "Commitments and Contingencies," to the Notes to Consolidated Financial Statements for more information.


⁽³⁾	Tax liabilities of $2.9 million related to uncertain tax positions are not included in the table because we cannot reliably estimate the timing and amount of future payments, if any.

We had $4.2 million of standby letters of credit and bank guarantees outstanding as of December 30, 2017. These consisted of $2.2 million related to customer performance guarantees, $1.3 million value added tax and customs' licenses, and $0.7 million related to property leases. We had $8.7 million of standby letters of credit and bank guarantees outstanding as of December 31, 2016. These consisted of $4.5 million related to property leases, $3.1 million related to customer performance guarantees and $1.1 million related to a value added tax and customs authorities' licenses.

Off-Balance Sheet Arrangements

As of December 30, 2017, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with U.S. GAAP. These accounting principles require us to make certain estimates, assumptions and judgments that can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, as well as the reported amounts of revenue and expenses during the periods presented. See Note 2, "Significant Accounting Policies," to the Notes to Consolidated Financial Statements, which in included in Item 8. Financial Statements and Supplementary Data," which describes our significant accounting policies and methods used in preparation of our Consolidated Financial Statements. Management believes that the estimates, assumptions and judgments upon which they rely are reasonable based upon information available to them at the time that these estimates and judgments are made. To the extent there are material differences between these estimates and actual results, our consolidated financial statements will be affected.

We believe our critical accounting policies and estimates are those related to revenue recognition, stock-based compensation, inventory valuation, accrued warranty and accounting for income taxes. Management considers these policies critical because they are both important to the portrayal of our financial condition and results of operations, and they require management to make judgments and estimates about inherently uncertain matters.

Revenue Recognition

Many of our product sales are sold in combination with installation and deployment services along with initial hardware and software support. Periodically, our product sales are also sold with spares management, on-site hardware replacement services, network management operations, software subscription, extended hardware warranty or training. Initial software and hardware support services are generally delivered over a one-year period in connection with the initial purchase. Software warranty provides customers with maintenance releases during the warranty support period and hardware warranty provides replacement or repair of equipment that fails to perform in line with specifications. Software subscription service includes software warranty and additionally provides customers with rights to receive unspecified software product upgrades released during the support period.

includes the day-to-day operation of a customer's network. These services are generally delivered on an annual basis. Training services include the right to a specified number of instructor-led or web based training classes, and installation and deployment services may include customer site assessments, equipment installation and testing. These services are generally delivered over a 30 to 120 day period.

We recognize product revenue when all of the following have occurred: (1) we have entered into a legally binding arrangement with the customer; (2) delivery has occurred, which is when product title and risk of loss have transferred to the customer; (3) customer payment is deemed fixed or determinable; and (4) collectability is reasonably assured.

We allocate revenue to each element in our multiple-element arrangements based upon their relative selling prices. We determine the selling price for each deliverable based on a selling price hierarchy. The selling price for a deliverable is based on its 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. Revenue allocated to each element is then recognized when the basic revenue recognition criteria for that element has been met.

VSOE of selling price is used in the selling price allocation in all instances where it exists. VSOE of selling price for products and services is determined when a substantial majority of the selling prices fall within a reasonable range when sold separately. In certain instances, we are not able to establish VSOE for all deliverables in an arrangement with multiple elements. This mainly occurs where insufficient standalone sales transactions have occurred or where pricing for that element has not been consistent.

TPE of selling price can be established by evaluating largely interchangeable competitor products or services in standalone sales to similarly situated customers. As our products contain a significant element of proprietary technology and the solution offered differs substantially from that of competitors, it is typically difficult to obtain the reliable standalone competitive pricing necessary to establish TPE.

ESP represents the best estimate of the price at which we would transact a sale if the product or service was sold on a standalone basis. We determine ESP for a product or service by considering multiple factors including, but not limited to market conditions, competitive landscape, gross margin objectives and pricing practices. The determination of ESP is made through formal approval by our management, taking into consideration the overall go-to-market pricing strategy.

As our go-to-market strategies evolve, we may modify our pricing practices in the future, which could result in changes in selling prices, including both VSOE and ESP. As a result, our future revenue recognition for multiple element arrangements could differ from that recorded in the current period. We regularly review VSOE, TPE, and ESP and maintain internal controls over the establishment and update of these inputs.

We limit the amount of revenue recognition for delivered elements to the amount that is not contingent on the future delivery of products or services, future performance obligations or subject to customer-specified return or refund privileges. We evaluate each deliverable in an arrangement to determine whether they represent separate units of accounting.

We have a limited number of software offerings, which are not required to deliver the tangible product’s essential functionality and can be sold separately. Revenue from sales of these software products and related post-contract support will continue to be accounted for under software revenue recognition rules. Our multiple-element arrangements may therefore have a software deliverable that is subject to the existing software revenue recognition guidance. The revenue for these multiple-element arrangements is allocated to the software deliverable and the non-software deliverables based on the relative selling prices of all of the deliverables in the arrangement using the hierarchy in the revenue recognition accounting guidance. Revenue related to these offerings have historically not been material.

Services revenue includes software subscription services, installation and deployment services, spares management, on-site hardware replacement services, network operations management, extended hardware warranty services and training. Revenue from software subscription, spares management, on-site hardware replacement services, network operations management and extended hardware warranty contracts is deferred and is recognized ratably over the contractual support period, which is generally one year. Revenue related to training and installation and deployment services is recognized as the services are completed.

Contracts and customer purchase orders are generally used to determine the existence of an arrangement. In addition, shipping documents and customer acceptances, when applicable, are used to verify delivery and transfer of title. Revenue is recognized only when title and risk of loss pass to customers and when the revenue recognition criteria have been met. In instances where acceptance of the product occurs upon formal written acceptance, revenue is recognized only after such written acceptance has been received. We assess whether the fee is fixed or determinable based on the payment terms associated with the transaction. Payment terms to customers generally range from net 30 to 120 days from invoice, which are considered to be standard payment terms. We assess our ability to collect from our customers based primarily on the creditworthiness and past payment history of the customer.

For sales to resellers, the same revenue recognition criteria apply. It is our practice to identify an end user prior to shipment to a reseller. We do not offer rights of return or price protection to our resellers.

Shipping charges billed to customers are included in product revenue and related shipping costs are included in product cost. We report revenue net of any required taxes collected from customers and remitted to government authorities, with the collected taxes recorded as current liabilities until remitted to the relevant government authority.

Stock-Based Compensation

Stock-based compensation cost is measured at the grant date based on the fair value of the award, and is recognized as expense over the requisite service period (generally the vesting period) under the straight-line amortization method. The expected forfeiture rate was estimated based on our historical forfeiture data and compensation costs were recognized only for those equity awards expected to vest. The estimation of the forfeiture rate required judgment, and to the extent actual forfeitures differed from expectations, changes in estimate were recorded as an adjustment in the period when such estimates were revised. We historically recorded stock-based compensation expense by applying the forfeiture rates and adjusted estimated forfeiture rates to actual. During the third fiscal quarter beginning on June 26, 2016, we elected to early adopt ASU 2016-09. We also elected to change our accounting policy to account for forfeitures when they occur on a modified retrospective basis.

We make a number of estimates and assumptions in determining stock-based compensation related to stock options including the following:


•	The expected term represents the weighted-average period that the stock options are expected to be outstanding prior to being exercised. The expected term is estimated based on our historical data on employee exercise patterns and post vesting termination behavior to estimate expected exercises over the contractual term of grants.

•

Expected volatility of our stock has been historically based on the weighted-average implied and historical volatility of Infinera and its peer group. The peer group is comprised of similar companies in the same industrial sector. As we gained more historical volatility data, the weighting of our own data in the expected volatility calculation associated with options gradually increased to 100% by 2013.

We estimate the fair value of the rights to acquire stock under our ESPP using the Black-Scholes option pricing formula. Our ESPP provides for consecutive six-month offering periods and we use our own historical volatility data in the valuation of ESPP shares.

We granted performance stock units (“PSUs”) to our executive officers and senior management in 2015, 2016 and 2017 as part of our annual refresh grant process. These PSUs entitle our executive officers and senior management to receive a number of shares of our common stock based on its stock price performance compared to a specified target composite index for the same period. These PSUs vest over the span of one year, two years and three years, and the number of shares to be issued upon vesting ranges from zero to two times the number of PSUs granted depending on the relative performance of our common stock price compared to the target composite index. This performance metric is classified as a market condition.

We use a Monte Carlo simulation model to determine the fair value of PSUs on the date of grant. The Monte Carlo simulation model is based on a discounted cash flow approach, with the simulation of a large number of possible stock price outcomes for our stock and the target composite index. The use of the Monte

Carlo simulation model requires the input of a number of assumptions including expected volatility of our stock price, expected volatility of target composite index, correlation between changes in our stock price and changes in the target composite index, risk-free interest rate, and expected dividends as applicable. Expected volatility of our stock is based on the weighted-average historical volatility of our stock. Expected volatility of target composite index is based on the historical data. Correlation is based on the historical relationship between our stock price and the target composite index average. The risk-free interest rate is based upon the treasury zero-coupon yield appropriate for the term of the PSU as of the grant date. The expected dividend yield is zero for us as we do not expect to pay dividends in the future. The expected dividend yield for the target composite index is the annual dividend yield expressed as a percentage of the composite average of the target composite index on the grant date.

In addition, we have granted other PSUs to certain employees that only vest upon the achievement of specific operational performance criteria.

Accounting for Income Taxes

On December 22, 2017, Staff Accounting Bulletin No. 118 (“SAB 118”) was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. In accordance with SAB 118, we determined an adjustment to deferred tax assets, along with a corresponding adjustment to valuation allowance, which resulted in no tax expense recorded in connection with the re-measurement of certain deferred tax assets and liabilities. Additionally, we have provisionally recorded no tax expense in connection with the transition tax on the mandatory deemed repatriation of foreign earnings, based upon an aggregate tax loss of our foreign subsidiaries, as a reasonable estimate at December 30, 2017. Additional work may be necessary for a more detailed analysis of our deferred tax assets and liabilities and our historical foreign earnings. Any subsequent adjustment to these amounts will be recorded in 2018 when the analysis is complete.

As part of the process of preparing our consolidated financial statements, we are required to estimate our taxes in each of the jurisdictions in which we operate. We estimate actual current tax expense together with assessing temporary differences resulting from different treatment of items, such as accruals and allowances not currently deductible for tax purposes. These differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheets. In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in our consolidated statements of operations become deductible expenses under applicable income tax laws or loss, or credit carryforwards are utilized. Accordingly, realization of our deferred tax assets is dependent on future taxable income within the respective jurisdictions against which these deductions, losses and credits can be utilized within the applicable future periods.

We must assess the likelihood that some portion or all of our deferred tax assets will be recovered from future taxable income within the respective jurisdictions, and to the extent we believe that recovery does not meet the “more-likely-than-not” standard, we must establish a valuation allowance. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets. In evaluating the need for a full or partial valuation allowance, all positive and negative evidence must be considered, including our forecasts of taxable income over the applicable carryforward periods, our current financial performance, our market environment, and other factors. Based on the available objective evidence, at December 30, 2017, management believes it is not more likely than not that the domestic net deferred tax assets will be realizable in the foreseeable future. Accordingly, the domestic net deferred tax assets are subject to a full valuation allowance. To the extent that we determine that deferred tax assets are realizable on a more likely than not basis, and an adjustment is needed, that adjustment will be recorded in the period that the determination is made.

Inventory Valuation

Inventories consist of raw materials, work-in-process and finished goods and are stated at standard cost adjusted to approximate the lower of actual cost or market. Costs are recognized utilizing the first-in, first-out method. Market value is based upon an estimated selling price reduced by the estimated cost of disposal. The determination of market value involves numerous judgments including estimated average selling prices based upon recent sales volumes, industry trends, existing customer orders, current contract price, future demand and pricing and technological obsolescence of our products.

Inventory that is obsolete or in excess of our forecasted demand or is anticipated to be sold at a loss is written down to its estimated net realizable value based on historical usage and expected demand. In valuing our inventory costs and deferred inventory costs, we considered whether the utility of the products delivered or expected to be delivered at less than cost, primarily comprised of common equipment, had declined. We concluded that, in the instances where the utility of the products delivered or expected to be delivered was less than cost, it was appropriate to value the inventory costs and deferred inventory costs at cost or market, whichever is lower, thereby recognizing the cost of the reduction in utility in the period in which the reduction occurred or can be reasonably estimated. We have, therefore, recognized inventory write-downs as necessary in each period in order to reflect inventory at the lower of cost or market.

We consider whether we should accrue losses on firm purchase commitments related to inventory items. Given that the net realizable value of common equipment is below contracted purchase price, we have also recorded losses on these firm purchase commitments in the period in which the commitment is made. When the inventory parts related to these firm purchase commitments are received, that inventory is recorded at the purchase price less the accrual for the loss on the purchase commitment.

Accrued Warranty

We warrant that our products will operate substantially in conformity with product specifications. Hardware warranties provide the purchaser with protection in the event that the product does not perform to product specifications. During the warranty period, the purchaser’s sole and exclusive remedy in the event of such defect or failure to perform is limited to the correction of the defect or failure by repair, refurbishment or replacement, at our sole option and expense. Our hardware warranty periods generally range from one to five years from date of acceptance for hardware and our software warranty is 90 days. Upon delivery of our products, we provide for the estimated cost to repair or replace products that may be returned under warranty. The hardware warranty accrual is based on actual historical returns and cost of repair experience and the application of those historical rates to our in-warranty installed base. The provision for warranty claims fluctuates depending upon the installed base of products and the failure rates and costs of repair associated with these products under warranty. Furthermore, our costs of repair vary based on repair volume and our ability to repair, rather than replace, defective units. In the event that actual product failure rates and costs to repair differ from our estimates, revisions to the warranty provision are required. In addition, from time to time, specific hardware warranty accruals may be made if unforeseen technical problems arise with specific products. We regularly assess the adequacy of our recorded warranty liabilities and adjust the amounts as necessary.

ITEM 7A.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Currency Risk

We operate in international markets, which expose us to market risk associated with foreign currency exchange rate fluctuations between the U.S. dollar and various foreign currencies, the most significant of which is the euro and Swedish kronor (“SEK”). Historically, the majority of our revenue contracts are denominated in U.S. dollars, with the most significant exception being in Europe, where we invoice primarily in euros and SEK. Additionally, a portion of our expenses, primarily the cost of personnel for research and development, sales and sales support to deliver technical support on our products and professional services, and the cost to manufacture, are denominated in foreign currencies, primarily the Indian rupee, the euro, SEK and the British pound. Revenue resulting from selling in local currencies and costs incurred in local currencies are exposed to foreign currency exchange rate fluctuations that can affect our operating income. As exchange rates vary, operating income may differ from expectations.

We currently enter into foreign currency exchange forward contracts to reduce the impact of currency exchange rate movements on certain transactions, but do not cover all foreign-denominated transactions and therefore do not entirely eliminate the impact of fluctuations in exchange rates that could negatively affect our results of operations and financial condition.

We enter into foreign currency exchange forward contracts to reduce the impact of foreign currency fluctuations on accounts receivable and restricted cash denominated in euros and British pounds. As a result, we do not expect a significant impact to our results from a change in exchange rates on foreign denominated accounts receivable balances and restricted cash in the near-term. Gains and losses on these contracts are intended to offset the impact of foreign exchange rate fluctuations on the underlying foreign currency denominated accounts receivables and restricted cash. Accordingly, the effect of an immediate 10% adverse change in foreign exchange rates on these transactions during 2017 would not be material to our results of operations.

During 2017, we also entered into foreign currency exchange contracts to reduce the volatility of cash flows primarily related to forecasted revenues and expenses denominated in euros, British pounds and SEK. The contracts are generally settled for U.S. dollars, euros and British pounds at maturity under an average rate method agreed to at inception of the contracts. The gains and losses on these foreign currency derivatives are recorded to the consolidated statement of operations line item, in the current period, to which the item that is being economically hedged is recorded. The effect of an immediate 10% adverse change in foreign exchange rates on these transactions during 2017 would not be material to our results of operations.

Interest Rate Sensitivity

We had cash and cash equivalents, short-term and long-term investments, and short-term and long-term restricted cash totaling $300.1 million and $360.0 million as of December 30, 2017 and December 31, 2016, respectively. As of December 30, 2017, we have invested in certificates of deposit, money market funds, commercial paper, U.S. agency notes, corporate bonds and U.S. treasuries. The unrestricted cash and cash equivalents are held for working capital purposes. We do not enter into investments for speculative purposes. We believe that we do not have any material exposure to changes in the fair value as a result of changes in interest rates. Declines in interest rates, however, will reduce future investment income. If overall interest rates fell by 10% in 2017 and 2016, our interest income would have declined approximately $0.3 million and $0.2 million, respectively, assuming consistent investment levels.

Market Risk and Market Interest Risk

Holders may convert the Notes prior to maturity upon the occurrence of certain circumstances. This early conversion period ended on November 30, 2017, with no early conversions to date. For all conversions that occur on or after December 1, 2017, we have elected a cash settlement method. If our common stock price is above the initial conversion price of $12.58 upon conversion or at maturity, the amount of cash required to pay the conversion premium is not fixed and would increase if our common stock price increases.

As of December 30, 2017, the fair value of the Notes was $149.1 million. The fair value was calculated using a valuation model. The fair value of the Notes is subject to interest rate risk, market risk and other factors due to the convertible feature. The fair value of the Notes will generally increase as interest rates fall and decrease as interest rates rise. In addition, the fair value of the Notes will generally increase as our common

stock price increases and will generally decrease as our common stock price declines in value. The interest and market value changes affect the fair value of the Notes but do not impact our financial position, cash flows or results of operations due to the fixed nature of the debt obligation. Additionally, we do not carry the Notes at fair value. We present the fair value of the Notes for required disclosure purposes only.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Infinera Corporation (the Company) as of December 30, 2017 and December 31, 2016, and the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity and cash flows for each of the three years in the period ended December 30, 2017, and the related notesand the financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the “financial statements”). In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Company at December 30, 2017 and December 31, 2016, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 30, 2017, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 30, 2017, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 27, 2018 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements.

Report of Ernst & Young LLP, Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Infinera Corporation

Opinion on Internal Control over Financial Reporting

We have audited Infinera Corporation’s internal control over financial reporting as of December 30, 2017, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Infinera Corporation (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 30, 2017, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets as of December 30, 2017 and December 31, 2016, and the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity and cash flows for each of the three years in the period ended December 30, 2017, and the related notes and the financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the “financial statements”) of the Company and our report dated February 27, 2018 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

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

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

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Basis of Presentation

Infinera Corporation (“Infinera” or the “Company”), headquartered in Sunnyvale, California, was founded in December 2000 and incorporated in the State of Delaware. Infinera is a leader in optical transport networking solutions, providing equipment, software and services to telecommunications service providers, internet content providers, cable providers, wholesale and enterprise carriers, research and education institutions, enterprise customers, and government entities across the globe. Optical transport networks are deployed by customers facing significant demand for optical bandwidth prompted by increased use of high-speed internet access, business Ethernet services, mobile broadband, cloud-based services, high-definition video streaming services, virtual and augmented reality, and the Internet of Things (IoT).

During the third quarter of 2015, the Company completed its public offer to the shareholders of Transmode AB (“Transmode”), acquiring 95.8% of the outstanding common shares and voting interest in Transmode. This acquisition was accounted for as a business combination, and accordingly, the Company has consolidated the financial results of Transmode with its financial results for the period from August 20, 2015, the date the acquisition closed (the “Acquisition Date”). The noncontrolling interest position is reported as a separate component of consolidated equity attributable to Transmode's shareholders. The noncontrolling interest in the Transmode entity's net loss is reported as a separate component of consolidated net income attributable to Transmode's shareholders.

In August 2016, the Company received advance title and paid an undisputed purchase price of $16.8 million to acquire the remaining 4.2% of Transmode shares not tendered in the initial offer. The additional $16.8 million paid resulted in the elimination of the noncontrolling interest and an increase in additional paid-in capital. During 2017, in association with the compulsory acquisition proceedings in accordance with Swedish law, the Company paid $0.5 million to the minority shareholders of Transmode based on the final determination of the arbitration tribunal.

The Company operates and reports financial results on a fiscal year of 52 or 53 weeks ending on the last Saturday of December in each year. Accordingly, fiscal year 2017 was a 52-week year that ended on December 30, 2017. Fiscal year 2016 was a 53-week year that ended on December 31, 2016, and 2015 was a 52-week year that ended on December 26, 2015. The next 53-week year will end on December 31, 2022.

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated. The Company reclassified certain amounts reported in previous periods to conform to the current presentation.

2. Significant Accounting Policies

Use of Estimates

The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). These accounting principles require the Company to make certain estimates, assumptions and judgments that can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, as well as the reported amounts of revenue and expenses during the periods presented. Significant estimates, assumptions and judgments made by management include revenue recognition, stock-based compensation, inventory valuation, accrued warranty, business combinations and accounting for income taxes. Other estimates, assumptions and judgments made by management include restructuring and other related costs, allowances for sales returns, allowances for doubtful accounts, useful life and recoverability of property, plant and equipment, fair value measurement of the liability component of the convertible senior notes, cost-method investment and derivative instruments. Management believes that the estimates, assumptions and judgments upon which they rely are reasonable based upon information available to them at the time that these estimates and judgments are made. To the extent there are material differences between these estimates and actual results, the Company’s consolidated financial statements will be affected.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Revenue Recognition

Many of the Company's product sales are sold in combination with installation and deployment services along with initial hardware and software support. Periodically, the Company's product sales are also sold with spares management, on-site hardware replacement services, network management operations, software subscription, extended hardware warranty or training. Initial software and hardware support services are generally delivered over a one-year period in connection with the initial purchase. Software warranty provides customers with maintenance releases during the warranty support period and hardware warranty provides replacement or repair of equipment that fails to perform in line with specifications. Software subscription service includes software warranty and additionally provides customers with rights to receive unspecified software product upgrades released during the support period.

Spares management and on-site hardware replacement services include the replacement of defective units at customer sites in accordance with specified service level agreements. Network operations management includes the day-to-day operation of a customer's network. These services are generally delivered on an annual basis. Training services include the right to a specified number of instructor-led or web based training classes, and installation and deployment services may include customer site assessments, equipment installation and testing. These services are generally delivered over a 30 to120 day period.

The Company recognizes product revenue when all of the following have occurred: (1) it has entered into a legally binding arrangement with the customer; (2) delivery has occurred, which is when product title and risk of loss have transferred to the customer; (3) customer payment is deemed fixed or determinable; and (4) collectability is reasonably assured.

The Company allocates revenue to each element in its multiple-element arrangements based upon their relative selling prices. The Company determines the selling price for each deliverable based on a selling price hierarchy. The selling price for a deliverable is based on its 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. Revenue allocated to each element is then recognized when the basic revenue recognition criteria for that element has been met.

VSOE of selling price is used in the selling price allocation in all instances where it exists. VSOE of selling price for products and services is determined when a substantial majority of the selling prices fall within a reasonable range when sold separately. In certain instances, the Company is not able to establish VSOE for all deliverables in an arrangement with multiple elements. This mainly occurs where insufficient standalone sales transactions have occurred or where pricing for that element has not been consistent.

TPE of selling price can be established by evaluating largely interchangeable competitor products or services in standalone sales to similarly situated customers. As the Company’s products contain a significant element of proprietary technology and the solution offered differs substantially from that of competitors, it is typically difficult to obtain the reliable standalone competitive pricing necessary to establish TPE.

ESP represents the best estimate of the price at which the Company would transact a sale if the product or service was sold on a standalone basis. The Company determines ESP for a product or service by considering multiple factors including, but not limited to market conditions, competitive landscape, gross margin objectives and pricing practices. The determination of ESP is made through formal approval by the Company’s management, taking into consideration the overall go-to-market pricing strategy. The Company regularly reviews VSOE, TPE and ESP and maintains internal controls over the establishment and update of these inputs.

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, future performance obligations or subject to customer-specified return or refund privileges. The Company evaluates each deliverable in an arrangement to determine whether they represent separate units of accounting.

The Company has a limited number of software offerings which are not required to deliver the tangible product’s essential functionality and can be sold separately. Revenue from sales of these software products and related post-contract support will continue to be accounted for under software revenue recognition rules. The Company’s multiple-element arrangements may therefore have a software deliverable that is subject to the

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

existing software revenue recognition guidance. The revenue for these multiple-element arrangements is allocated to the software deliverable and the non-software deliverables based on the relative selling prices of all of the deliverables in the arrangement using the hierarchy in the revenue recognition accounting guidance. Revenue related to these offerings have historically not been material.

Contracts and customer purchase orders are generally used to determine the existence of an arrangement. In addition, shipping documents and customer acceptances, when applicable, are used to verify delivery and transfer of title. Revenue is recognized only when title and risk of loss pass to customers and when the revenue recognition criteria have been met. In instances where acceptance of the product occurs upon formal written acceptance, revenue is recognized only after such written acceptance has been received. The Company assesses whether the fee is fixed or determinable based on the payment terms associated with the transaction. Payment terms to customers generally range from net 30 to 120 days from invoice, which are considered to be standard payment terms. The Company assesses its ability to collect from its customers based primarily on the creditworthiness and past payment history of the customer.

For sales to resellers, the same revenue recognition criteria apply. It is the Company’s practice to identify an end-user prior to shipment to a reseller. The Company does not offer rights of return or price protection to its resellers.

Shipping charges billed to customers are included in product revenue and related shipping costs are included in product cost. The Company reports revenue net of any required taxes collected from customers and remitted to government authorities, with the collected taxes recorded as current liabilities until remitted to the relevant government authority.

Commission Expense

Sales commissions are recorded as sales and marketing expense and accrued compensation and related benefits. The Company generally records commission expense when it bills the customers; thus no contract acquisition costs are capitalized.

Stock-Based Compensation

Stock-based compensation cost is measured at the grant date based on the fair value of the award, and is recognized as expense over the requisite service period (generally the vesting period) under the straight-line amortization method. The expected forfeiture rate was estimated based on the Company's historical forfeiture data and compensation costs were recognized only for those equity awards expected to vest. The estimation of the forfeiture rate required judgment, and to the extent actual forfeitures differed from expectations, changes in estimate were recorded as an adjustment in the period when such estimates were revised. The Company historically recorded stock-based compensation expense by applying the forfeiture rates and adjusted estimated forfeiture rates to actual. During the third fiscal quarter beginning on June 26, 2016, the Company elected to early adopt ASU 2016-09. The Company also elected to change its accounting policy to account for forfeitures when they occur on a modified retrospective basis.

The Company makes a number of estimates and assumptions in determining stock-based compensation related to stock options including the following:


•	The expected term represents the weighted-average period that the stock options are expected to be outstanding prior to being exercised. The expected term is estimated based on the Company’s historical data on employee exercise patterns and post vesting termination behavior to estimate expected exercises over the contractual term of grants.

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)


•	Expected volatility of the Company’s stock is based on the weighted-average implied and historical volatility of the Company.

The Company estimates the fair value of the rights to acquire stock under its Employee Stock Purchase Plan (“ESPP”) using the Black-Scholes option pricing formula. The Company’s ESPP provides for consecutive six-month offering periods and the Company uses its own historical volatility data in the valuation of ESPP shares.

The Company accounts for the fair value of restricted stock units (“RSUs”) using the closing market price of the Company’s common stock on the date of grant. For new-hire grants, RSUs typically vest ratably on an annual basis over four years. For annual refresh grants, RSUs typically vest ratably on an annual basis over three or four years.

The Company granted performance stock units (“PSUs”) to its executive officers and senior management in 2015, 2016 and 2017 as part of the Company's annual refresh grant process. These PSUs entitle the Company's executive officers and senior management to receive a number of shares of the Company's common stock based on its stock price performance compared to a specified target composite index for the same period. These PSUs vest over the span of one year, two years and three years, and the number of shares to be issued upon vesting ranges from zero to two times the number of PSUs granted depending on the relative performance of the Company's common stock price compared to the targeted composite index. This performance metric is classified as a market condition.

The Company uses a Monte Carlo simulation model to determine the fair value of PSUs on the date of grant. The Monte Carlo simulation model is based on a discounted cash flow approach, with the simulation of a large number of possible stock price outcomes for the Company's stock and the target composite index. The use of the Monte Carlo simulation model requires the input of a number of assumptions including expected volatility of the Company's stock price, expected volatility of target composite index, correlation between changes in the Company's stock price and changes in the target composite index, risk-free interest rate, and expected dividends as applicable. Expected volatility of the Company's stock is based on the weighted-average historical volatility of its stock. Expected volatility of target composite index is based on the historical and implied data. Correlation is based on the historical relationship between the Company's stock price and the target composite index average. The risk-free interest rate is based upon the treasury zero-coupon yield appropriate for the term of the PSU as of the grant date. The expected dividend yield is zero for the Company as it does not expect to pay dividends in the future. The expected dividend yield for the target composite index is the annual dividend yield expressed as a percentage of the composite average of the target composite index on the grant date.

In addition, the Company has granted other PSUs to certain employees that only vest upon the achievement of specific operational performance criteria. The Company assesses the achievement status of these PSUs on a quarterly basis and records the related stock-based compensation expenses based on the estimated achievement payout.

Research and Development

All costs to develop the Company’s hardware products are expensed as incurred. Software development costs are capitalized beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. Generally, the Company’s software products are released soon after technological feasibility has been established. As a result, costs subsequent to achieving technological feasibility have not been significant and all software development costs have been expensed as incurred.

Advertising

All advertising costs are expensed as incurred. Advertising expenses in 2017, 2016 and 2015 were $1.8 million, $1.9 million and $1.8 million, respectively.

Accounting for Income Taxes

On December 22, 2017, Staff Accounting Bulletin No. 118 (“SAB 118”) was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts and Jobs Act (the “Tax Act”). In accordance with SAB 118, the Company determined an adjustment to deferred tax assets, along with a corresponding adjustment to valuation allowance, which resulted in no tax expense recorded in connection with the re-measurement of certain deferred tax assets and liabilities. Additionally, the Company has provisionally recorded no tax expense in connection with the transition tax on the mandatory deemed repatriation of foreign earnings, based upon an aggregate tax loss of its foreign subsidiaries, as a reasonable estimate at December 30, 2017. Additional work may be necessary for a more detailed analysis of the Company's deferred tax assets and liabilities and its historical foreign earnings. Any subsequent adjustment to these amounts will be recorded in 2018 when the analysis is complete.

As part of the process of preparing the Company’s consolidated financial statements, the Company is required to estimate its taxes in each of the jurisdictions in which it operates. The Company estimates actual current tax expense together with assessing temporary differences resulting from different treatment of items, such as accruals and allowances not currently deductible for tax purposes. These differences result in deferred tax assets and liabilities, which are included in the Company’s consolidated balance sheets. In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in the Company’s consolidated statements of operations become deductible expenses under applicable income tax laws, or loss or credit carryforwards are utilized. Accordingly, realization of the Company’s deferred tax assets is dependent on future taxable income within the respective jurisdictions against which these deductions, losses and credits can be utilized within the applicable future periods.

The Company must assess the likelihood that some portion or all of its deferred tax assets will be recovered from future taxable income within the respective jurisdictions, and to the extent the Company believes that recovery does not meet the “more-likely-than-not” standard, the Company must establish a valuation allowance. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management judgment is required in determining the Company’s provision for income taxes, the Company’s deferred tax assets and liabilities and any valuation allowance recorded against its net deferred tax assets. In evaluating the need for a full or partial valuation allowance, all positive and negative evidence must be considered, including the Company's forecasts of taxable income over the applicable carryforward periods, its current financial performance, its market environment, and other factors. Based on the available objective evidence, at December 30, 2017, management believes it is not more likely than not that the domestic net deferred tax assets will be realizable in the foreseeable future. Accordingly, the domestic net deferred tax assets are subject to a full valuation allowance. To the extent that the Company determines that deferred tax assets are realizable on a more likely than not basis, and an adjustment is needed, that adjustment will be recorded in the period that the determination is made.

Foreign Currency Translation and Transactions

The Company considers the functional currencies of its foreign subsidiaries to be the local currency. Assets and liabilities recorded in foreign currencies are translated at the exchange rate as of the balance sheet date, and costs and expenses are translated at average exchange rates in effect during the period. Equity transactions are translated using historical exchange rates. The effects of foreign currency translation adjustments are recorded as a separate component of accumulated other comprehensive income (loss) in the accompanying consolidated balance sheets.

For all non-functional currency account balances, the re-measurement of such balances to the functional currency will result in either a foreign exchange transaction gain or loss which is recorded to other gain (loss), net in the same period that the re-measurement occurred. Aggregate foreign exchange transactions recorded in 2017, 2016 and 2015 were a loss of $0.3 million, a loss of $1.8 million and a gain of $2.4 million, respectively.

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The Company entered into foreign currency exchange forward contracts to reduce the impact of foreign exchange fluctuations on earnings from accounts receivable balances denominated in euros and British pounds, and restricted cash denominated in euros.

During 2017, the Company also entered into foreign currency exchange contracts to reduce the volatility of cash flows primarily related to forecasted revenues and expenses denominated in euros, British pounds and Swedish kronor (“SEK”). The contracts are generally settled for U.S. dollars, euro and British pound at maturity under an average rate method agreed to at inception of the contracts. The gains and losses on these foreign currency derivatives are recorded to the consolidated statement of operations line item, in the current period, to which the item that is being economically hedged is recorded.

Cash, Cash Equivalents and Short-term and Long-term Investments

The Company considers all highly liquid instruments with an original maturity at the date of purchase of 90 days or less to be cash equivalents. These instruments may include cash, money market funds, commercial paper and U.S. treasuries. The Company also maintains a portion of its cash in bank deposit accounts which, at times, may exceed federally insured limits. The Company has not experienced any losses in such accounts.

Cash, cash equivalents and short-term investments consist of highly-liquid investments in certificates of deposits, money market funds, commercial paper, U.S. agency notes, corporate bonds and U.S. treasuries. Long-term investments primarily consist of certificates of deposits, commercial paper, U.S. agency notes, corporate bonds and U.S. treasuries. The Company considers all debt instruments with original maturities at the date of purchase greater than 90 days and remaining time to maturity of one year or less to be short-term investments. The Company classifies debt instruments with remaining maturities greater than one year as long-term investments, unless the Company intends to settle its holdings within one year or less and in such case it is considered to be short-term investments. The Company determines the appropriate classification of its marketable securities at the time of purchase and re-evaluates such designations as of each balance sheet date.

Available-for-sale investments are stated at fair market value with unrealized gains and losses recorded in accumulated other comprehensive income (loss) in the Company’s consolidated balance sheets. The Company evaluates its available-for-sale marketable debt securities for other-than-temporary impairments and records any credit loss portion in other income (expense), net, in the Company’s consolidated statements of operations. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity and for any credit losses incurred on these securities. Gains and losses are recognized when realized in the Company’s consolidated statements of operations under the specific identification method. Because the Company does not intend to sell its debt securities and it is not more likely than not that it will be required to sell the investment before recovery of their amortized cost basis, which may be maturity.

Fair Value Measurement

Pursuant to the accounting guidance for fair value measurements and its subsequent updates, fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.

Valuation techniques used by the Company are based upon observable and unobservable inputs. Observable or market inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s assumptions about market participant assumptions based on the best information available. Observable inputs are the preferred source of values. These two types of inputs create the following

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

fair value hierarchy:



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

Level 2	–	Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3	–	Prices or valuations that require management inputs that are both significant to the fair value measurement and unobservable.

The Company measures its cash equivalents, foreign currency exchange forward contracts, and debt securities at fair value and classifies its securities in accordance with the fair value hierarchy on a recurring basis. The Company’s money market funds and U.S. treasuries are classified within Level 1 of the fair value hierarchy and are valued based on quoted prices in active markets for identical securities.

The Company classifies the following assets within Level 2 of the fair value hierarchy as follows:

Certificates of Deposit

The Company reviews market pricing and other observable market inputs for the same or similar securities obtained from a number of industry standard data providers. In the event that a transaction is observed for the same or similar security in the marketplace, the price on that transaction reflects the market price and fair value on that day. In the absence of any observable market transactions for a particular security, the fair market value at period end would be equal to the par value. These inputs represent quoted prices for similar assets or these inputs have been derived from observable market data.

Commercial Paper

The Company reviews market pricing and other observable market inputs for the same or similar securities obtained from a number of industry standard data providers. In the event that a transaction is observed for the same or similar security in the marketplace, the price on that transaction reflects the market price and fair value on that day and then follows a revised accretion schedule to determine the fair market value at period end. In the absence of any observable market transactions for a particular security, the fair market value at period end is derived by accreting from the last observable market price. These inputs represent quoted prices for similar assets or these inputs have been derived from observable market data accreted mathematically to par.

U.S. Agency Notes

The Company reviews trading activity and pricing for its U.S. agency notes as of the measurement date. When sufficient quoted pricing for identical securities is not available, the Company uses market pricing and other observable market inputs for similar securities obtained from a number of industry standard data providers. These inputs represent quoted prices for similar assets in active markets or these inputs have been derived from observable market data.

Corporate Bonds

The Company reviews trading activity and pricing for each of the corporate bond securities in its portfolio as of the measurement date and determines if pricing data of sufficient frequency and volume in an active market exists in order to support Level 1 classification of these securities. If sufficient quoted pricing for identical securities is not available, the Company obtains market pricing and other observable market inputs for similar securities from a number of industry standard data providers. In instances where multiple prices exist for similar securities, these prices are used as inputs into a distribution-curve to determine the fair market value at period end.

INFINERA CORPORATION

Foreign Currency Exchange Forward Contracts

As discussed in Note 5, "Derivative Instruments," to the Notes to Consolidated Financial Statements, the Company mainly holds non-speculative foreign exchange forward contracts to hedge certain foreign currency exchange exposures. The Company estimates the fair values of derivatives based on quoted market prices or pricing models using current market rates. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including interest rate curves, credit risk, foreign exchange rates, and forward and spot prices for currencies.

The Company classifies the following assets and liabilities within Level 3 of the fair value hierarchy and applies fair value accounting on a nonrecurring basis, only if impairment is indicated:

Facilities-related Charges

The Company estimates the fair value of its facilities-related charges associated with the 2017 Restructuring Plan, based on estimated future discounted cash flows and unobservable inputs, which included the amount and timing of estimated sublease rental receipts that the Company could reasonably obtain over the remaining lease term and the discount rate.

Cost-method Investment

The Company estimates the fair value of its cost-method investment by using the guideline public company method and the guideline transaction method of the market approach to determine the implied total equity value on a minority interest basis. These analyses require management to make assumptions and estimates regarding industry and economic factors, future operating results and discount rates.

Accounts Receivable and Allowances for Doubtful Accounts

Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company reviews its aging by category to identify significant customers or invoices with known dispute or collectability issues. The Company makes judgments as to its ability to collect outstanding receivables based on various factors including ongoing customer credit evaluations and historical collection experience. The Company provides an allowance for receivable amounts that are potentially uncollectible and when receivables are determined to be uncollectible, amounts are written off.

Allowances for Sales Returns

Customer product returns are approved on a case by case basis. Specific reserve provisions are made based upon a specific review of all the approved product returns where the customer has yet to return the products to generate the related sales return credit at the end of a period. Estimated sales returns are provided for as a reduction to revenue. At December 30, 2017, December 31, 2016 and December 26, 2015, revenue was reduced for estimated sales returns by $0.9 million, $0.6 million and $0.6 million, respectively.

Concentration of Risk

Financial instruments that are potentially subject to concentrations of credit risk consist primarily of cash equivalents, short-term investments, long-term investments and accounts receivable. Investment policies have been implemented that limit investments to investment-grade securities.

The risk with respect to accounts receivable is mitigated by ongoing credit evaluations that the Company performs on its customers. As the Company continues to expand its sales internationally, it may experience increased levels of customer credit risk associated with those regions. Collateral is generally not required for accounts receivable but may be used in the future to mitigate credit risk associated with customers located in certain geographical regions.

As of December 30, 2017, two customers accounted for approximately over 10% of the Company's net accounts receivable balance. One customer accounted for approximately 11% of the Company's net accounts receivable balance, and another customer, which completed a merger in late 2017, was combination of two of our historically larger customers, accounted for approximately 16% of the Company's net accounts receivable

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

balance. As of December 31, 2016, two customers accounted for approximately 17% and 15% of the Company’s net accounts receivable balance, respectively.

To date, a few of the Company’s customers have accounted for a significant portion of its revenue. One customer, which completed a merger in late 2017 as mentioned above, was a combination of two of the Company's historically larger customers who merged in 2017 and accounted for approximately 18% of the Company's revenue in 2017. These two historically larger customers each individually accounted for approximately 16% and 8% of the of the Company's revenue in 2016, respectively, and approximately 17% and 13% of the Company's revenue in 2015, respectively. No other customers accounted for over 10% of the Company's revenue for these periods.

The Company depends on sole source or limited source suppliers for several key components and raw materials. The Company generally purchases these sole source or limited source components and raw materials through standard purchase orders and does not have long-term contracts with many of these limited-source suppliers. While the Company seeks to maintain sufficient reserve stock of such components and raw materials, the Company’s business and results of operations could be adversely affected if any of our sole source or limited source suppliers suffer from capacity constraints, lower than expected yields, deployment delays, work stoppages or any other reduction or disruption in output.

Derivative Instruments

The Company is exposed to foreign currency exchange rate fluctuations in the normal course of its business. As part of its risk management strategy, the Company uses derivative instruments, specifically forward contracts, to reduce the impact of foreign exchange fluctuations on earnings. The forward contracts are with one high-quality institution and the Company monitors the creditworthiness of the counter parties consistently. The Company’s objective is to offset gains and losses resulting from these exposures with gains and losses on the derivative contracts used to hedge them, thereby reducing volatility of earnings or protecting fair values of assets. None of the Company’s derivative instruments contain credit-risk related contingent features, any rights to reclaim cash collateral or any obligation to return cash collateral. The Company does not have any leveraged derivatives. The Company does not use derivative contracts for trading or speculative purposes.

The Company enters into foreign currency exchange forward contracts to manage its exposure to fluctuations in foreign exchange rates that arise primarily from its euro and British pound denominated receivables and euro denominated restricted cash balance amounts that are pledged as collateral for certain stand-by letters of credit. Gains and losses on these contracts are intended to offset the impact of foreign exchange rate changes on the underlying foreign currency denominated accounts receivables and restricted cash, and therefore, do not subject the Company to material balance sheet risk. The Company also entered into foreign currency exchange contracts to reduce the volatility of cash flows primarily related to forecasted revenues and expenses denominated in euros, British pounds and SEK. These contracts are generally settled for U.S. dollars, euros and British pound at maturity under an average rate method agreed to at inception of the contracts. The forward contracts are with one high-quality institution and the Company consistently monitors the creditworthiness of the counterparty.

Inventory Valuation

Inventory that is obsolete or in excess of the Company’s forecasted demand or is anticipated to be sold at a loss is written down to its estimated net realizable value based on historical usage and expected demand. In valuing its inventory costs and deferred inventory costs, the Company considered whether the utility of the products delivered or expected to be delivered at less than cost, primarily comprised of common equipment, had declined. The Company concluded that, in the instances where the utility of the products delivered or expected to be delivered was less than cost, it was appropriate to value the inventory costs and deferred inventory costs at

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

cost or market, whichever is lower, thereby recognizing the cost of the reduction in utility in the period in which the reduction occurred or can be reasonably estimated. The Company has, therefore, recognized inventory write-downs as necessary in each period in order to reflect inventory at the lower of actual cost or market.

The Company considers whether it should accrue losses on firm purchase commitments related to inventory items. Given that the net realizable value of common equipment is below contractual purchase price, the Company has also recorded losses on these firm purchase commitments in the period in which the commitment is made. When the inventory parts related to these firm purchase commitments are received, that inventory is recorded at the purchase price less the accrual for the loss on the purchase commitment.

Property, Plant and Equipment

Property, plant and equipment are stated at cost. This includes enterprise-level business software that the Company customizes to meets its specific operational needs. Depreciation is calculated using the straight-line method over the estimated useful lives of the respective assets. Leasehold improvements are amortized using the straight-line method over the shorter of the lease term or estimated useful life of the asset. An assumption of lease renewal where a renewal option exists is used only when the renewal has been determined to be reasonably assured. Repair and maintenance costs are expensed as incurred. The estimated useful life for each asset category is as follows:



	Estimated Useful Lives
Building	20 years
Laboratory and manufacturing equipment	1.5 to 10 years
Furniture and fixtures	3 to 5 years
Computer hardware and software	1.5 to 7 years
Leasehold and building improvements	1 to 10 years

The Company regularly reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable or that the useful life is shorter than originally estimated. If impairment indicators are present and the projected future undiscounted cash flows are less than the carrying value of the assets, the carrying values are reduced to the estimated fair value. If assets are determined to be recoverable, but the useful lives are shorter than originally estimated, the carrying value of the assets is depreciated over the newly determined remaining useful lives.

Accrued Warranty

The Company warrants that its products will operate substantially in conformity with product specifications. Hardware warranties provide the purchaser with protection in the event that the product does not perform to product specifications. During the warranty period, the purchaser’s sole and exclusive remedy in the event of such defect or failure to perform is limited to the correction of the defect or failure by repair, refurbishment or replacement, at the Company’s sole option and expense. The Company's hardware warranty periods generally range from one to five years from date of acceptance for hardware and the Company's software warranty is 90 days. Upon delivery of the Company's products, the Company provides for the estimated cost to repair or replace products that may be returned under warranty. The hardware warranty accrual is based on actual historical returns and cost of repair experience and the application of those historical rates to the Company's in-warranty installed base. The provision for warranty claims fluctuates depending upon the installed base of products and the failure rates and costs of repair associated with these products under warranty. Furthermore, the Company's costs of repair vary based on repair volume and its ability to repair, rather than replace, defective units. In the event that actual product failure rates and costs to repair differ from the Company's estimates, revisions to the warranty provision are required. In addition, from time to time, specific hardware warranty accruals may be made if unforeseen technical problems arise with specific products. The Company regularly assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Amortization of Intangible Assets

Intangible assets with finite lives are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets. In-process research and development represents the fair value of incomplete research and development projects that have not reached technological feasibility as of the date of acquisition. Initially, these assets are not subject to amortization. Once projects have been completed they are transferred to developed technology, which are subject to amortization, while assets related to projects that have been abandoned are impaired and expensed to research and development.

Impairment of Intangible Assets and Goodwill

Goodwill is evaluated for impairment on an annual basis in the fourth quarter of the Company's fiscal year, and whenever events or changes in circumstances indicate the carrying amount of goodwill may not be recoverable. The Company has elected to first assess qualitative factors to determine whether it is more likely than not that the fair value of its single reporting unit is less than its carrying amount. If the Company determines that it is more likely than not that the fair value of its single reporting unit is less than its carrying amount, then the two-step goodwill impairment test will be performed. The first step, identifying a potential impairment, compares the fair value of its single reporting unit with its carrying amount. If the carrying amount exceeds its fair value, the second step will be performed; otherwise, no further step is required. The second step, measuring the impairment loss, compares the implied fair value of the goodwill with the carrying amount of the goodwill. Any excess of the goodwill carrying amount over the implied fair value is recognized as an impairment loss. The Company evaluates events and changes in circumstances that could indicate carrying amounts of purchased intangible assets may not be recoverable. When such events or changes in circumstances occur, the Company assesses the recoverability of these assets by determining whether or not the carrying amount will be recovered through undiscounted expected future cash flows. If the total of the future undiscounted cash flows is less than the carrying amount of an asset, the Company records an impairment loss for the amount by which the carrying amount of the asset exceeds the fair value of the asset.

Restructuring and Other Related Costs

The Company records costs associated with exit activities related to restructuring plans in accordance with ASC 420, “Exit or Disposal Cost Obligations.” Liabilities for costs associated with an exit or disposal activity are recognized in the period in which the liability is incurred. The timing of the associated cash payments is dependent upon the type of exit cost and extend over an approximately four-year period. The Company records restructuring cost liabilities in “Accrued Expenses” and "Other Long-term Liabilities" in the Consolidated Balance Sheet.

Restructuring costs include termination costs, facility consolidation and closure costs, equipment write-downs and inventory write-downs. One-time termination benefits are recognized as a liability at estimated fair value when the approved plan of termination has been communicated to employees, unless employees must provide future service, in which case the benefits are recognized ratably over the future service period. Ongoing termination benefits arrangements are recognized as a liability at estimated fair value when the amount of such benefits becomes estimable and payment is probable. For the facility-related restructuring costs, the Company recognizes a liability upon exiting all or a portion of a leased facility and meeting cease-use and other requirements. The amount of restructuring costs is based on the fair value of the lease obligation for the abandoned space, which includes a sublease assumption that could be reasonably obtained.

Restructuring charges require significant estimates and assumptions, including sublease income and expenses for severance and other employee separation costs. Management estimates involve a number of risks and uncertainties, some of which are beyond control, including future real estate market conditions and the Company's ability to successfully enter into subleases or termination agreements with terms as favorable as those assumed when arriving at its estimates. The Company monitors these estimates and assumptions on at least a quarterly basis for changes in circumstances and any corresponding adjustments to the accrual are recorded in its statement of operations in the period when such changes are known.

Recent Accounting Pronouncements

In May 2017, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update 2017-09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting” (“ASU 2017-09”), which amends the scope of modification accounting for share-based payment arrangements, and 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 under Topic 718. This guidance is effective for the Company in its first quarter of fiscal 2018, with early adoption permitted. The Company does not expect the new guidance to have any material impact on its consolidated financial statements.

In January 2017, the FASB issued Accounting Standards Update 2017-04, “Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). The guidance eliminates Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The same one-step impairment test will be applied to goodwill at all reporting units, even those with zero or negative carrying amounts. Entities will be required to disclose the amount of goodwill at reporting units with zero or negative carrying amounts. ASU 2017-04 will be effective for the Company's annual or any interim goodwill impairment tests in its first quarter of fiscal 2020. The Company is currently evaluating the impact the adoption of ASU 2017-04 will have on its consolidated financial statements.

In November 2016, the FASB issued Accounting Standards Update 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash” (“ASU 2016-18”), which requires that a 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. As such, restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and ending-of-period total amounts shown on the statement of cash flows. The Company is required to adopt ASU 2016-18 on a retrospective basis for fiscal years, and for interim periods within those fiscal years, beginning with its first quarter of fiscal 2018. Early adoption is permitted, including adoption in an interim period. Subsequent to the adoption of ASU 2016-18, the change in restricted cash would be excluded from the change in cash flows from investing and financing activities and included in the change in total cash, restricted cash and cash equivalents as reported in the statement of cash flows. Upon adoption of ASU 2016-18, the Company will amend the presentation in its consolidated statements of cash flows to include restricted cash with cash and cash equivalents and it will retrospectively reclassify all periods presented.

In August 2016, the FASB issued Accounting Standards Update 2016-15, “Statement of Cash Flows (Topic 320): Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”), which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice in how certain transactions are presented and classified in the statement of cash flows. The Company early adopted ASU 2016-15 on a retrospective basis during the third quarter of fiscal 2017. The Company's adoption of 2016-15 had no impact on its consolidated statements of cash flows.

In June 2016, the FASB issued Accounting Standards Update 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”), which requires measurement and recognition of expected credit losses for financial assets held. This guidance is effective for the Company in its first quarter of fiscal 2020 and early adoption is permitted. The Company is currently evaluating the impact the adoption of ASU 2016-13 will have on its consolidated financial statements.

In May 2016, the FASB issued Accounting Standards Update 2016-11, “Revenue Recognition (Topic 605) and Derivatives and Hedging (Topic 815): Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting (SEC Update)” (“ASU 2016-11”), which rescinds various standards codified as part of Topic 605, Revenue Recognition in relation to the future adoption of Topic 606. These rescissions include changes to topics pertaining to revenue and expense recognition for freight services in process, accounting for shipping and handling fees and costs, and accounting for consideration given by a vendor to a customer. This guidance is effective for the Company in its first quarter of fiscal 2018 and early adoption is permitted. The Company is currently evaluating the impact the adoption of ASU 2016-11 will have on its consolidated financial statements.

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

In February 2016, the FASB issued Accounting Standards Update 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), which amends the existing accounting standards for leases. The new standard requires lessees to record a right-of-use asset and a corresponding lease liability on the balance sheet (with the exception of short-term leases). For lessees, leases will continue to be classified as either operating or financing in the income statement. This guidance is effective for the Company in its first quarter of fiscal 2019 and early adoption is permitted. ASU 2016-02 is required to be applied with a modified retrospective approach and requires application of the new standard at the beginning of the earliest comparative period presented. The Company is currently evaluating the impact the adoption of ASU 2016-02 will have on its consolidated financial statements and expects to have increases in the assets and liabilities of its consolidated balance sheets.

In July 2015, the FASB issued Accounting Standards Update 2015-11, “Simplifying the Measurement of Inventory” (“ASU 2015-11”), to simplify the guidance on the subsequent measurement of inventory, excluding inventory measured using last-in, first-out or the retail inventory method. Under ASU 2015-11, inventory should be at the lower of cost and net realizable value. The Company adopted ASU 2015-11 during the first quarter of fiscal 2017. The Company's adoption of 2015-11 had no impact on the Company's financial position, results of operations or cash flows.

In May 2014, the FASB issued Accounting Standards Update 2014-09, “Revenue from Contracts from Customers (Topic 606)” (“ASU 2014-09”), which creates a single, joint revenue standard that is consistent across all industries and markets for companies that prepare their financial statements in accordance with U.S. GAAP. Under ASU 2014-09, an entity is required to recognize revenue upon the transfer of promised goods or services to customers in an amount that reflects the consideration the entity expects to be entitled to receive in exchange for those goods or services. In August 2015, the FASB issued Accounting Standards update 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” which deferred the effective date of ASU 2014-09 by one year with early adoption permitted beginning after December 15, 2016. The updated standard is effective for interim and annual periods beginning after December 15, 2017. In April 2016, the FASB issued Accounting Standards Update 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing,” which clarifies the implementation guidance on identifying performance obligations and licensing. In May 2016, the FASB issued Accounting Standards Update 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients,” which amends the guidance on collectability, noncash consideration, presentation of sales tax and transition. In December 2016, the FASB issued Accounting Standards Update 2016-20, “Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers,” to increase stakeholders' awareness of the proposals and to expedite improvements to ASU 2014-09. ASU 20140-09 also includes Subtopic 340-40, "Other Assets and Deferred Costs - Contracts with Customers," which requires the deferral of incremental costs of obtaining a contract with a customer. Collectively, the Company refers to ASU 2014-09 and Subtopic 340-40 as the new standard.”

These standards will be effective for the Company's first quarter of 2018. The Company has determined that it will elect to adopt the standard using the modified retrospective method with the cumulative effect recognized as an adjustment to the opening balance of its accumulated deficit as of December 31, 2017. Prior periods will not be retrospectively adjusted and will continue to be reported under the accounting standards in effect for those periods. However, the Company will include additional disclosures of the amount by which each financial statement line item is affected in the current reporting period during 2018, as compared to the guidance that was in effect before the change.

The Company has substantially completed its assessment of the impact of the new standard but is still evaluating the adjustment to the opening balance of its accumulated deficit. The Company’s assessment will be finalized during the first quarter of 2018. The Company has performed an assessment of nearly all of its open customer contracts under the new guidance. The new standard will impact the Company's operations, policies and accounting in the areas of customer purchase commitments, contract termination rights, variable consideration, stand-alone selling price and capitalization of costs to obtain a contract.

To evaluate the impact of the new revenue standards on its accounting policies, internal controls, processes and system requirements, the Company assigned internal resources in addition to the engagement of third party service providers to assist in this evaluation. The Company has completed the implementation of a new IT solution as part of the adoption of the new standard. In addition, the Company has made and will continue to make investments in systems and processes to enable timely and accurate reporting under the new

revenue standard. The Company is currently implementing the necessary operational and internal control structural changes.

3. Fair Value Measurements

During 2017 and 2016, there were no transfers of assets or liabilities between Level 1 and Level 2. As of December 30, 2017 and December 31, 2016, none of the Company’s existing securities were classified as Level 3 securities.

In connection with the 2017 Restructuring Plan, the Company calculated the fair value of the $7.3 million in facilities-related charges based on estimated future discounted cash flows and classified the fair value as a Level 3 measurement due to the significance of unobservable inputs, which included the amount and timing of estimated sublease rental receipts that the Company could reasonably obtain over the remaining lease term and the discount rate. See Note 8, “Restructuring and Other Related Costs,” to the Notes to Consolidated Financial Statements for more information on the 2017 Restructuring Plan.

As of December 30, 2017, the Company determined that its cost-method investment was impaired, resulting in an impairment charge of $1.9 million to adjust the carrying value to estimated fair value. The Company classified the fair value as a Level 3 measurement due to the significance of unobservable inputs. The Company used the guideline public company method and the guideline transaction method of the market approach to determine the implied total equity value on a minority interest basis. These analyses require management to make assumptions and estimates regarding industry and economic factors, future operating results and discount rates. See Note 4, “Cost-method Investment,” to the Notes to Consolidated Financial Statements for more information.

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

insignificant for all periods. The specific identification method is used to account for gains and losses on available-for-sale investments.

As of December 30, 2017, the Company had $263.9 million of cash, cash equivalents and short-term investments, including $62.1 million of cash and cash equivalents held by its foreign subsidiaries. The Company's cash in foreign locations is used for operational and investing activities in those locations, and the Company does not currently have the need or the intent to repatriate those funds to the United States.


4.	Cost-method Investments

In 2016, the Company invested $7.0 million in a privately-held company. In addition, this investment included a customer supply agreement and warrants to purchase up to $10.0 million of additional shares of preferred stock. The warrants vest and become exercisable upon certain conditions being met. Additionally, in 2016, the Company recognized a gain of $9.0 million from the sale of an existing cost-method investment. As of December 30, 2017 and December 31, 2016, the Company's cost-method investment balance was $5.1 million and $7.0 million, respectively.

This investment is accounted for as cost-basis investments as the Company owns less than 20% of the voting securities and does not have the ability to exercise significant influence over operating and financial policies of the entity. The Company regularly evaluates the carrying value of its cost-method investment for impairment. If the Company believes that the carrying value of the cost basis investment is in excess of estimated fair value, the Company’s policy is to record an impairment charge in other income (expense), net, in the accompanying consolidated statements of operations.

Based on the Company's review during the fourth quarter of 2017, it determined that the carrying amount of its cost-method investment exceeded its fair value and the decline in value was determined to be other-than-temporary. As a result, the Company recorded an impairment charge of $1.9 million to adjust the carrying value to estimated fair value.

During 2016 and 2015, no impairment charges were recorded as there had not been any events or changes in circumstances that the Company believed would have a significant adverse effect on the fair value of its investment.

5. Derivative Instruments

Foreign Currency Exchange Forward Contracts

The Company transacts business in various foreign currencies and has international sales, cost of sales, and expenses denominated in foreign currencies, and carries foreign-currency-denominated monetary assets and liabilities, subjecting the Company to foreign currency risk. The Company’s primary foreign currency risk management objective is to protect the U.S. dollar value of future cash flows and minimize the volatility of reported earnings. The Company utilizes foreign currency forward contracts, primarily short term in nature.

Historically, the Company enters into foreign currency exchange forward contracts to manage its exposure to fluctuation in foreign exchange rates that arise from its euro and British pound denominated receivables and restricted cash balances. Gains and losses on these contracts are intended to offset the impact of foreign exchange rate fluctuations on the underlying foreign currency denominated accounts receivables and restricted cash, and therefore, do not subject the Company to material balance sheet risk.

During 2017, the Company also entered into foreign currency exchange contracts to reduce the volatility of cash flows primarily related to forecasted revenues and expenses denominated in euros, British pound and SEK. The contracts are generally settled for U.S. dollars, euros and British pounds at maturity under an average rate method agreed to at inception of the contracts. The gains and losses on these foreign currency derivatives are recorded to the consolidated statement of operations line item, in the current period, to which the item that is being economically hedged is recorded.

In April 2015, the Company entered into a foreign currency exchange forward contract with a notional amount of SEK 831 million ($95.3 million) to hedge currency exposures associated with the cash consideration of the offer to acquire Transmode. In July 2015, the Company entered into a series of additional foreign currency

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

exchange option contracts to purchase up to an additional SEK 1.3 billion ($153.8 million) and to sell up to SEK 650 million ($76.9 million), which achieves the economic equivalent of a “participating forward” in order to hedge the anticipated foreign currency cash outflows associated with the additional cash consideration related to the enhanced offer to acquire the shares of Transmode. As these contracts are not formally designated as hedges, the gains and losses were recognized in the statement of operations. For 2015, the Company recorded a realized gain of $1.6 million, which was included in other gain (loss), net, in the accompanying consolidated statements of operations.

The before-tax effect of foreign currency exchange forward contracts was a loss of $3.5 million for 2017, a loss of $0.9 million for 2016 and a gain of $3.8 million in 2015, included in other gain (loss), net, in the consolidated statements of operations. In each of these periods, the impact of the gross gains and losses were offset by foreign exchange rate fluctuations on the underlying foreign currency denominated amounts.

As of December 30, 2017, the Company did not designate foreign currency exchange forward contracts as hedges for accounting purposes and accordingly, changes in the fair value are recorded in the accompanying consolidated statements of operations. These contracts were with one high-quality institution and the Company consistently monitors the creditworthiness of the counterparties.

The fair value of derivative instruments not designated as hedging instruments in the Company’s consolidated balance sheets was as follows (in thousands):



	As of December 30, 2017							As of December 31, 2016

6.	Goodwill and Intangible Assets

Goodwill

Goodwill is recorded when the purchase price of an acquisition exceeds the fair value of the net tangible and identified intangible assets acquired.

The following table presents details of the Company’s goodwill for the year ended December 30, 2017 (in thousands):



Balance as of December 31, 2016	$	176,760

Total intangible assets with finite lives	$	141,484	$	(33,295	)	$	108,189	4.7
Acquired in-process technology	286		—			286
Total intangible assets	$	141,770	$	(33,295	)	$	108,475

The gross carrying amount of intangible assets and the related amortization expense of intangible assets may change due to the effects of foreign currency fluctuations as these assets are denominated in SEK. Amortization expense was $26.6 million and $26.0 million for the years ended December 30, 2017 and December 31, 2016, respectively.

Intangible assets are carried at cost less accumulated amortization. Amortization expenses are recorded to the appropriate cost and expense categories. During 2017, the Company recorded an impairment charge to research and development expenses of $0.3 million related to other intangible assets, which the Company has determined that the carrying value will not be recoverable. During the first quarter of 2017, the Company transferred $0.3 million of its in-process technology to developed technology, which is being amortized over a useful life of five years.

During 2016, the Company transferred $3.8 million of its in-process technology to developed technology, which is being amortized over a maximum useful life of seven years. Additionally, during 2016, the Company recorded an impairment charge of $11.3 million related to in-process research and development, resulting from the Company's decision to abandon previously acquired in-process technologies.

8.	Restructuring and Other Related Costs

In the fourth quarter of 2017, the Company implemented a plan to restructure its worldwide operations (the “2017 Restructuring Plan”) in order to reduce expenses and establish a more cost-effective structure that better aligns the Company's operations with its long-term strategies. As part of the 2017 Restructuring Plan, the Company is making several changes it believes will help its research and development efficiency, with consolidation of its development sites, including closure of its Beijing, China design center, process changes to more broadly leverage the Company's engineering resources across regions and product line development, and prioritization of research and development initiatives. Outside of engineering, the Company has also made changes to allow it to operate more efficiently as it scales the business, including reducing the Company's facilities footprint and writing off certain equipment that will not be utilized in the future. Finally, the Company realigned its inventory levels to match its new technology cadence and go to market strategies. As of December 30, 2017, the 2017 Restructuring Plan had been substantially completed and we do not expect to record significant future charges under this plan in 2018.

The following table presents restructuring and other related costs included in cost of revenue and operating expenses in the accompanying consolidated statements of operations under the 2017 Restructuring Plan (in thousands):

10.	Basic and Diluted Net Income (Loss) Per Common Share

Basic net income (loss) per common share is computed by dividing net income (loss) attributable to Infinera Corporation by the weighted average number of common shares outstanding during the period. Diluted net income (loss) attributable to Infinera Corporation per common share is computed using net income (loss) attributable to Infinera Corporation and the weighted average number of common shares outstanding plus potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include the assumed exercise of outstanding stock options, assumed release of outstanding RSU and PSUs, and assumed issuance of common stock under the ESPP using the treasury stock method. Potentially dilutive common shares also include the assumed conversion of the Notes from the conversion spread (as defined and discussed in Note 11, “Convertible Senior Notes” to the Notes to Consolidated Financial Statements). The Company includes the common shares underlying PSUs in the calculation of diluted net income per share only when they become contingently issuable. In net loss periods, these potentially diluted common shares have been excluded from the diluted net loss calculation.

The Company incurred net losses during 2017 and 2016, and as a result, potential common shares from stock options, RSUs, PSUs, assumed release of outstanding stock under the ESPP and assumed conversion of the Notes from the conversion spread were not included in the diluted shares used to calculate net loss per share, as their inclusion would have been anti-dilutive.

During 2015, the Company included the dilutive effects of the Notes in the calculation of diluted net income per common share as the applicable average market price was above the conversion price of the Notes. The effects of other potentially dilutive common shares from stock options, RSUs, PSUs and assumed release of outstanding stock under the ESPP were not included in the calculation of diluted net income per share for 2015 because their effect were anti-dilutive under the treasury stock method or the performance condition of the award had not been met.

Prior to the fourth quarter of 2017, upon conversion of the Notes, the Company intended to pay cash equal to the lesser of the aggregate principal amount or the conversion value of the Notes being converted, therefore, only the conversion spread relating to the Notes were included in the Company's diluted net income per share calculation. In November 2017, the Company made an election to settle any remaining conversion obligation in cash. See Note 11, ”Convertible Senior Notes” to the Notes to Consolidated Financial Statements for more information.

The following sets forth the potentially dilutive shares excluded from the computation of the diluted net income (loss) per share because their effect was anti-dilutive (in thousands):

11.	Convertible Senior Notes

In May 2013, the Company issued the $150.0 million of 1.75% convertible senior notes due June 1, 2018 (the “Notes”), which will mature on June 1, 2018, unless earlier purchased by the Company or converted. Interest is payable semi-annually in arrears on June 1 and December 1 of each year, commencing December 1, 2013. The net proceeds to the Company were approximately $144.5 million and were intended to be used for working capital and other general corporate purposes. To date, the Company has not utilized the net proceeds due to its sufficient cash position.

The Notes are governed by an indenture dated as of May 30, 2013 (the “Indenture”), between the Company, as issuer, and U.S. Bank National Association, as trustee. The Notes are unsecured and do not contain any financial covenants or any restrictions on the payment of dividends, the incurrence of senior debt or other indebtedness, or the issuance or repurchase of securities by the Company.

Upon conversion, it is the Company's intention to pay cash equal to the lesser of the aggregate principal amount or the conversion value of the Notes. For any remaining conversion obligation, the Company intends to pay cash. For all conversions that occur on or after December 1, 2017, the Company has elected a cash settlement method. The current conversion rate is 79.4834 shares of common stock per $1,000 principal amount of Notes, subject to anti-dilution adjustments. The initial conversion price is approximately $12.58 per share of common stock.

Throughout the term of the Notes, the conversion rate may be adjusted upon the occurrence of certain events, including for any cash dividends. Holders of the Notes will not receive any cash payment representing accrued and unpaid interest upon conversion of a Note. Accrued but unpaid interest will be deemed to be paid in full upon conversion rather than canceled, extinguished or forfeited. Holders may convert their Notes under the following circumstances:

•

during any fiscal quarter commencing after the fiscal quarter ending on September 28, 2013 (and only during such fiscal quarter) if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price on each applicable trading day (the “Stock Price Conversion Trigger”);


•	during the five business day period after any 5 consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day;


•	upon the occurrence of specified corporate events described under the Indenture, such as a consolidation, merger or binding share exchange; or


•	at any time on or after December 1, 2017 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their Notes at any time, regardless of the foregoing circumstances.

If the Company undergoes a fundamental change as defined in the Indenture governing the Notes, holders may require the Company to repurchase for cash all or any portion of their Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. In addition, upon the occurrence of a “make-whole fundamental change” (as defined in the Indenture), the Company will, in certain circumstances, increase the conversion rate by a number of additional shares for a holder that elects to convert its Notes in connection with such make-whole fundamental change.

The net carrying amounts of the debt obligation were as follows (in thousands):



	December 30, 2017			December 31, 2016
Principal	$	150,000		$	150,000
Unamortized discount ⁽¹⁾	(4,670		)	(15,114		)
Unamortized issuance cost ⁽¹⁾	(402		)	(1,300		)
Net carrying amount	$	144,928		$	133,586


⁽¹⁾	Unamortized debt conversion discount and issuance costs will be amortized over the remaining life of the Notes, which is approximately 5 months.

As of December 30, 2017 and December 31, 2016, the carrying amount of the equity component of the Notes was $43.3 million.

In accounting for the issuance of the Notes, the Company separated the Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar debt instrument that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the Notes. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount (“debt discount”) is amortized to interest expense over the term of the Notes.

In accounting for the issuance costs of $5.5 million related to the Notes, the Company allocated the total amount incurred to the liability and equity components of the Notes based on their relative values. Issuance costs attributable to the liability component were recorded as other non-current assets and will be amortized to interest expense over the term of the Notes. ASU 2015-03 requires an entity to present such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. The Company adopted ASU 2015-03 during the first quarter of 2016. The December 26, 2015 balance sheet was retrospectively adjusted to reclassify $2.1 million from other non-current assets to a reduction of the Notes payable liability.

The issuance costs attributable to the equity component were netted with the equity component in stockholders’ equity. Additionally, the Company initially recorded a deferred tax liability of $17.0 million in connection with the issuance of the Notes, and a corresponding reduction in valuation allowance. The impact of both was recorded to stockholders’ equity.

The Company determined that the embedded conversion option in the Notes does not require separate accounting treatment as a derivative instrument because it is both indexed to the Company’s own stock and would be classified in stockholder’s equity if freestanding.

The following table sets forth total interest expense recognized related to the Notes (in thousands):



	Years Ended
	December 30, 2017		December 31, 2016		December 26, 2015
Contractual interest expense	$	2,625	$	2,625	$	2,625
Amortization of debt issuance costs	898		813		735
Amortization of debt discount	10,444		9,447		8,546
Total interest expense	$	13,967	$	12,885	$	11,906

The coupon rate was 1.75%. For the years ended December 30, 2017 and December 31, 2016, the debt discount and debt issuance costs were amortized, using an annual effective interest rate of 10.23%, to interest expense over the term of the Notes.

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

As a result of the Notes maturing on June 1, 2018, the net carrying amount was reclassified from long-term debt to short-term debt in the Company's consolidated balance sheets during the second quarter of 2017. As of December 30, 2017, the fair value of the Notes was $149.1 million. The fair value was determined based on the quoted bid price of the Notes in an over-the-counter market on December 29, 2017. The Notes are classified as Level 2 of the fair value hierarchy.

During the third quarter of 2017, the closing price of the Company's common stock did not meet the Stock Price Conversion Trigger; therefore, holders of the Notes could not convert their Notes during the fourth quarter of 2017 pursuant to the Stock Price Conversion Trigger. The Notes became convertible at the option of the holders beginning on December 1, 2017 and will be convertible until the close of business on the second scheduled trading day immediately preceding the maturity date. Based on the closing price of the Company’s common stock of $6.33 on December 29, 2017 (the last trading day of the fiscal quarter), the if-converted value of the Notes did not exceed their principal amount.

12.Commitments and Contingencies

Operating Leases

The Company leases facilities under non-cancelable operating lease agreements. These leases have varying terms that range from one to 10 years, and contain leasehold improvement incentives, rent holidays and escalation clauses. In addition, some of these leases have renewal options for up to five years. The Company has contractual commitments to remove leasehold improvements and return certain properties to a specified condition when the leases terminate. At the inception of a lease with such conditions, the Company records an asset retirement obligation liability and a corresponding capital asset in an amount equal to the estimated fair value of the obligation. Asset retirement obligations were $3.5 million and $3.6 million as of December 30, 2017 and December 31, 2016, respectively. These obligations are classified as other long-term liabilities on the accompanying consolidated balance sheets.

The Company recognizes rent expense on a straight-line basis over the lease period factoring in leasehold improvement incentives, rent holidays and escalation clauses. Rent expense for all leases was $12.0 million, $8.6 million and $7.2 million for 2017, 2016 and 2015, respectively. The Company did not have any sublease rental income for 2017, 2016 and 2015.

Future annual minimum operating lease payments at December 30, 2017 were as follows (in thousands):



	2018		2019		2020		2021		2022		Thereafter		Total
Operating lease payments	$	11,319	$	10,015	$	8,595	$	2,306	$	413	$	61	$	32,709

In the fourth quarter of 2017, the Company implemented the 2017 Restructuring Plan, which included vacating certain leased facilities. See Note 8, "Restructuring and Other Related Costs," to the Notes to Consolidated Financial Statements for more information.

Purchase Commitments

The Company has service agreements with its major production suppliers, where the Company is committed to purchase certain parts. These obligations are typically less than the Company’s purchase needs. As of December 30, 2017, December 31, 2016 and December 26, 2015, these non-cancelable purchase commitments were $96.1 million, $111.9 million and $137.4 million, respectively.

Future purchase commitments at December 30, 2017 were as follows (in thousands):



	2018		2019		2020		2021		2022		Thereafter		Total

Legal Matters

On November 23, 2016, Oyster Optics, LLC (“Oyster Optics”) filed a complaint against the Company in the United States District Court for the Eastern District of Texas. The complaint asserts U.S. Patent Nos. 6,469,816, 6,476,952, 6,594,055, 7,099,592, 7,620,327, 8,374,511 and 8,913,898 (collectively, the “Oyster Optics patents in suit”). The complaint seeks unspecified damages and a permanent injunction. The Company believes that it does not infringe any valid and enforceable claim of the Oyster Optics patents in suit, and intends to defend this action vigorously. The Company filed its answer to Oyster Optics' complaint on February 3, 2017. On October 23, 2017, the Company filed a petition for Inter Partes Review (“IPR”) of one of the Oyster Optics patents in suit, U.S. Patent No. 8,913,898 (the “'898 patent”), with the U.S. Patent and Trademark Office, and, on December 1, 2017, the Company filed a second petition for IPR of the '898 patent. Other defendants have filed IPR petitions in connection with the Oyster Optics patents in suit. The Court has set a trial date for June 2018. The Company is currently unable to predict the outcome of this litigation and therefore cannot reasonably estimate the possible loss or range of loss, if any, arising from this matter.

On March 24, 2017, Core Optical Technologies, LLC (“Core Optical”) filed a complaint against the Company in the United States District Court for the Central District of California. The complaint asserts U.S. Patent No. 6,782,211 (the “Core Optical patent in suit”). The complaint seeks unspecified damages and a permanent injunction. The Company believes that it does not infringe any valid and enforceable claim of the Core Optical patent in suit, and intends to defend this action vigorously. The Company filed its answer to Core Optical's complaint on September 25, 2017. Because this action is in the early stages, the Company is unable to predict the outcome of this litigation at this time and therefore cannot reasonably estimate the possible loss or range of loss, if any, arising from this matter.

In addition to the matters described above, the Company is subject to various legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, the Company does not expect that the ultimate costs to resolve these matters will have a material effect on its consolidated financial position, results of operations or cash flows.

Loss Contingencies

The Company is subject to the possibility of various losses arising in the ordinary course of business. These may relate to disputes, litigation and other legal actions. In the preparation of its quarterly and annual financial statements, the Company considers the likelihood of loss or the incurrence of a liability, including whether it is probable, reasonably possible or remote that a liability has been incurred, as well as the Company’s ability to reasonably estimate the amount of loss, in determining loss contingencies. In accordance with U.S. GAAP, an estimated loss contingency is accrued when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The Company regularly evaluates current information to determine whether any accruals should be adjusted and whether new accruals are required. As of December 30, 2017, the Company has accrued the estimated liabilities associated with certain loss contingencies.

Indemnification Obligations

From time to time, the Company enters into certain types of contracts that contingently require it to indemnify parties against third party claims. The terms of such indemnification obligations vary. These contracts may relate to: (i) certain real estate leases under which the Company may be required to indemnify property owners for environmental and other liabilities, and other claims arising from the Company’s use of the applicable premises; and (ii) certain agreements with the Company’s officers, directors and certain key employees, under which the Company may be required to indemnify such persons for liabilities.

In addition, the Company has agreed to indemnify certain customers for claims made against the Company’s products, where such claims allege infringement of third party intellectual property rights, including, but not limited to, patents, registered trademarks, and/or copyrights. Under the aforementioned intellectual property indemnification clauses, the Company may be obligated to defend the customer and pay for the damages awarded against the customer under an infringement claim as well as the customer’s attorneys’ fees and costs. These indemnification obligations generally do not expire after termination or expiration of the agreement containing the indemnification obligation. In certain cases, there are limits on and exceptions to the Company’s potential liability for indemnification. Although historically, the Company has not made significant payments under these indemnification obligations, the Company cannot estimate the amount of potential future

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

payments, if any, that it might be required to make as a result of these agreements. The maximum potential amount of any future payments that the Company could be required to make under these indemnification obligations could be significant.

As permitted under Delaware law and the Company’s charter and bylaws, the Company has agreements whereby it indemnifies certain of its officers and each of its directors. The term of the indemnification period is for the officer’s or director’s lifetime for certain events or occurrences while the officer or director is, or was, serving at the Company’s request in such capacity. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements could be significant; however, the Company has a director and officer insurance policy that may reduce its exposure and enable it to recover all or a portion of any future amounts paid. As a result of its insurance policy coverage, the Company believes the estimated fair value of these indemnification agreements is minimal.

13.Guarantees

Product Warranties

Activity related to product warranty was as follows (in thousands):



	December 30, 2017			December 31, 2016
Beginning balance	$	40,342		$	38,844
Charges to operations	18,283			25,135

Change in estimate⁽¹⁾	(12,731		)	(6,753		)
Balance at the end of the period	$	30,909		$	40,342

⁽¹⁾

The Company records product warranty liabilities based on the latest quality and cost information available as of the date the revenue is recorded. The changes in estimate shown here are due to changes in overall actual failure rates, the mix of new versus used units related to replacement of failed units, and changes in the estimated cost of repair. As the Company's products mature over time, failure rates and repair costs generally decline leading to favorable changes in warranty reserves. In addition, during 2017, due to product quality improvements, the Company revised certain estimates used in calculating its product warranties that resulted in a one-time reduction to the warranty accrual of $2.2 million.

Letters of Credit and Bank Guarantees

The Company had $4.2 million of standby letters of credit and bank guarantees outstanding as of December 30, 2017. These consisted of $2.2 million related to customer performance guarantees, $1.3 million value added tax and customs' licenses, and $0.7 million related to property leases. The Company had $8.7 million of standby letters of credit and bank guarantees outstanding as of December 31, 2016. These consisted of $4.5 million related to property leases, $3.1 million related to customer performance guarantees and $1.1 million related to a value added tax and customs authorities' licenses.

As of December 30, 2017 and December 31, 2016, the Company has a line of credit for approximately $1.6 million and $1.1 million, respectively, to support the issuance of letters of credit, of which zero and $0.3 million had been issued and outstanding, respectively. The Company has pledged approximately $5.2 million and $4.5 million of assets of a subsidiary to secure this line of credit and other obligations as of December 30, 2017 and December 31, 2016, respectively.

14.	Stockholders’ Equity

2007 Equity Incentive Plan, 2016 Equity Incentive Plan and Employee Stock Purchase Plan

In February 2007, the Company’s board of directors adopted the 2007 Equity Incentive Plan (the “2007 Plan”) and the Company’s stockholders approved the 2007 Plan in May 2007. The Company reserved a total of 46.8 million shares of common stock for issuance under the 2007 Plan. Upon stockholder approval of the 2016 Equity Incentive Plan (the “2016 Plan”), the Company has ceased granting equity awards under the 2007 Plan, however the 2007 Plan will continue to govern the terms and conditions of the outstanding options and awards previously granted under the 2007 Plan. As of December 30, 2017, options to purchase 1.4 million shares of the Company's common stock were outstanding and 2.7 million RSUs were outstanding under the 2007 Plan.

In February 2016, the Company's board of directors adopted the 2016 Plan and the Company's stockholders approved the 2016 Plan in May 2016. In May 2017, the Company's stockholders approved an amendment to the 2016 Plan to increase the number of shares authorized for issuance under the 2016 Plan by 6.4 million shares. As of December 30, 2017, the Company reserved a total of 13.9 million shares of common stock for issuance of stock options, RSUs and PSUs to employees, non-employees, consultants and members of the Company's board of directors, pursuant to the 2016 Plan, plus any shares subject to awards granted under the 2007 Plan that, after the effective date of the 2016 Plan, expire, are forfeited or otherwise terminate without having been exercised in full to the extent such awards were exercisable, and shares issued pursuant to awards granted under the 2007 Plan that, after the effective date of the 2016 Plan, are forfeited to or repurchased by the Company due to failure to vest. The 2016 Plan has a maximum term of 10 years from the date of adoption, or it can be earlier terminated by the Company's board of directors.

The ESPP was adopted by the board of directors in February 2007 and approved by the stockholders in May 2007. The ESPP was last amended by the stockholders in May 2014 to increase the shares authorized under the ESPP to a total of 16.6 million shares of common stock. The ESPP has a 20-year term. Eligible employees may purchase the Company’s common stock through payroll deductions at a price equal to 85% of the lower of the fair market values of the stock as of the beginning or the end of six-month offering periods. An employee’s payroll deductions under the ESPP are limited to 15% of the employee’s compensation and employees may not purchase more than $25,000 of stock during any calendar year.

The aggregate intrinsic value of unexercised options is calculated as the difference between the closing price of the Company’s common stock of $6.33 at December 29, 2017 and the exercise prices of the underlying stock options. The aggregate intrinsic value of the options which have been exercised is calculated as the difference between the fair market value of the common stock at the date of exercise and the exercise price of the underlying stock options. The aggregate intrinsic value of unreleased RSUs and unreleased PSUs is calculated using the closing price of the Company's common stock of $6.33 at December 29, 2017. The aggregate intrinsic value of RSUs and PSUs released is calculated using the fair market value of the common stock at the date of release.

Restricted Stock Units

The Company granted RSUs to employees and members of the Company’s board of directors to receive shares of the Company’s common stock. All RSUs awarded are subject to each individual's continued service to the Company through each applicable vesting date. The Company accounted for the fair value of the RSUs using the closing market price of the Company’s common stock on the date of grant. Amortization of stock-based compensation expense related to RSUs in 2017, 2016 and 2015 was approximately $30.5 million, $29.6 million and $22.9 million, respectively.

Performance Stock Units

Pursuant to the 2007 Plan, the Company has granted PSUs to certain of the Company’s executive officers, senior management and certain employees. All PSUs awarded are subject to each individual's continued service to the Company through each applicable vesting date and if the performance metrics are not met within the time limits specified in the award agreements, the PSUs will be canceled.

A number of PSUs granted to the Company’s executive officers and senior management are based on the total shareholder return of the Company's common stock price as compared to the total shareholder return of the S&P North American Technology Multimedia Networking Index (“SPGIIPTR”) over the span of one year, two years and three years. The number of shares to be issued upon vesting of these PSUs range from zero to two times the target number of PSUs granted depending on the Company’s performance against the SPGIIPTR.

The ranges of estimated values of the PSUs granted that are compared to the SPGIIPTR, as well as the assumptions used in calculating these values were based on estimates as follows:

Loss before provision for income taxes from international operations was $22.6 million, $23.1 million and $6.3 million, respectively, for the years ended December 30, 2017, December 31, 2016 and December 26, 2015.

The provisions for (benefit from) income taxes differ from the amount computed by applying the statutory federal income tax rates as follows:



	Years Ended
	December 30, 2017		December 31, 2016		December 26, 2015
Expected tax (benefit) at federal statutory rate	(35.0	)%	(35.0	)%	35.0	%
State taxes, net of federal benefit	—	%	2.2	%	1.5	%

Other	—	%	(0.4	)%	—	%
Effective tax rate	(0.7	)%	(16.3	)%	2.1	%

The Company recognized an income tax benefit of $1.4 million on a loss before income taxes of $195.9 million, income tax benefit of $4.8 million on a loss before income taxes of $29.2 million and income tax expense of $1.1 million on income before income taxes of $52.0 million in fiscal years 2017, 2016 and 2015, respectively. The resulting effective tax rates were (0.7)%, (16.3)% and 2.1% for 2017, 2016 and 2015, respectively. The 2017 and 2016 effective tax rates differ from the expected statutory rate of 35% based on the Company's ability to benefit U.S. loss carryforwards, offset by state income taxes, non-deductible stock-based compensation expenses and foreign taxes provided on foreign subsidiary earnings. The lower 2017 income tax benefit compared to the 2016 income tax benefit primarily relates to a lower acquisition related amortization expenses and lower state income taxes offset by an increase in tax reserves, and taxable foreign profits in certain jurisdictions. The tax benefit for 2016 compared to tax expense in 2015 is primarily due to acquisition related

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

amortization expenses and charges lower state taxes, and reduction in tax reserves, offset by an increase in taxable foreign profits.

Because of the Company's U.S. operating loss in 2017 and significant loss carryforward position with a corresponding full valuation allowance in 2016 and 2015, it has not been subject to federal or state tax on U.S. income because of the availability of loss carryforwards, with the exception of amounts for certain states’ taxes for which the losses are limited by statute or amount in 2016 and more significantly in 2015, and federal and state taxes associated with a discontinued US subsidiary. If these losses and other tax attributes become fully utilized, taxes will increase significantly to a more normalized, expected rate on U.S. earnings. The release of transfer pricing reserves in the future will have a beneficial impact to tax expense, but the timing of the impact depends on factors such as expiration of the statute of limitations or settlements with tax authorities.

On December 22, 2017, the Tax Act was signed into law. The Tax Act significantly revises the U.S. corporate income tax regime by, among other things, lowering the federal corporate income tax rate from 35% to 21% effective January 1, 2018, while also imposing a repatriation tax on deemed repatriated earnings of the Company's foreign subsidiaries in 2017, and implementing a quasi-territorial tax system on future foreign earnings.

On December 22, 2017, SAB 118 was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. In accordance with SAB 118, the Company determined an adjustment to deferred tax assets, along with a corresponding adjustment to valuation allowance, which resulted in no tax expense recorded in connection with the re-measurement of certain deferred tax assets and liabilities from 35% to 21% to reflect the new corporate tax rate. Additionally, the Company has provisionally recorded no tax expense in connection with the transition tax on the mandatory deemed repatriation of foreign earnings, based upon an aggregate tax loss of its foreign subsidiaries, as a reasonable estimate at December 30, 2017. Additional work may be necessary for a more detailed analysis of the Company's deferred tax assets and liabilities and its historical foreign earnings. Any subsequent adjustment to these amounts will be recorded in 2018 when the analysis is complete.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Deferred income taxes reflect the net effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets are as follows, reduced by the effects of the change in the U.S. corporate tax rate from 35% to 21%, as applicable (in thousands):



	Years Ended
	December 30, 2017			December 31, 2016
Deferred tax assets:

Total deferred tax liabilities	$	(22,760	)	$	(33,988	)
Net deferred tax liabilities	$	(21,200	)	$	(25,210	)

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company must consider all positive and negative evidence, including the Company's forecasts of taxable income over the applicable carryforward periods, its current financial performance, its market environment, and other factors in evaluating the need for a full or partial valuation allowance against its net U.S. deferred tax assets. Based on the available objective evidence, management believes it is not more likely than not that the domestic net deferred tax assets will be realizable in the foreseeable future. Accordingly, the Company has provided a full valuation allowance against its domestic deferred tax assets, net of deferred tax liabilities, as of December 30, 2017 and December 31, 2016. The net deferred tax assets and full valuation allowance thereon as of December 30, 2017 reflects a reduction of approximately $66.1 million due to a lower effective tax rate under the Tax Act.

To the extent that the Company determines that deferred tax assets are realizable on a more likely than not basis, and an adjustment is needed, that adjustment will be recorded in the period that the determination is made and would generally decrease the valuation allowance and record a corresponding benefit to earnings.

As of December 30, 2017, the Company has net operating loss carryforwards of approximately $273.1 million for federal tax purposes and $138.8 million for state tax purposes. The carryforward balance reflects expected generation of both federal and state net operating losses for the year ended December 30, 2017. Federal net operating loss carryforwards will begin to expire in 2025 while certain unutilized California losses have expired in 2017. Additionally, the Company has federal research and development and foreign tax credits, and California research and development credits available to reduce future income taxes payable of approximately $52.6 million and $43.2 million, respectively, as of December 30, 2017. Infinera Canada Inc., an indirect wholly owned subsidiary, has Scientific Research and Experimental Development Expenditures (“SRED”)

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

credits available of $2.7 million to offset future Canadian income tax payable as of December 30, 2017. Federal credits will begin to expire in the year 2022 if not utilized and California research credits have no expiration date. Canadian SRED credits will begin to expire in the year 2030 if not fully utilized.

Under the Tax Reform Act of 1986, the amount of benefit from net operating loss and tax credit carryforwards may be impaired or limited in certain circumstances. Events which cause limitations in the amount of net operating losses that the Company may utilize in any one year include, but are not limited to, a cumulative ownership change of more than 50 percent as defined over a three-year testing period. As of December 30, 2017, the Company had determined that while ownership changes had occurred in the past, the resulting limitations were not significant enough to impact the utilization of the tax attributes against its taxable profits earned to date.

Prior to the enactment of the Tax Act, the Company’s policy with respect to undistributed foreign subsidiaries’ earnings was to consider those earnings to be indefinitely reinvested. Under the Tax Act, undistributed earnings of foreign subsidiaries are deemed to be repatriated for U.S. corporate tax purposes and a one-time toll tax at a reduced U.S. corporate tax rate is applicable in 2017. However, because of the aggregated net tax loss of our foreign subsidiaries, no tax is accruable in 2017. If and when funds are actually distributed in the form of dividends or otherwise, foreign withholding taxes may be applicable in some jurisdictions. The Company's policy with respect to certain undistributed foreign subsidiaries’ earnings is to continue to consider those earnings to be indefinitely reinvested and therefore the Company has not accrued such withholding taxes.

The aggregate changes in the balance of gross unrecognized tax benefits were as follows (in thousands):



	December 30, 2017			December 31, 2016			December 26, 2015
Beginning balance	$	22,282		$	19,130		$	16,978

Lapses of statute of limitations	(2		)	(688		)	(242		)
Ending balance	$	19,786		$	22,282		$	19,130

As of December 30, 2017, the cumulative unrecognized tax benefit was $19.8 million, of which $16.9 million was netted against deferred tax assets, which would have otherwise been subjected with a full valuation allowance. Of the total unrecognized tax benefit as of December 30, 2017, approximately $2.9 million, if recognized, would impact the Company’s effective tax rate.

As of December 30, 2017, December 31, 2016 and December 26, 2015, the Company had $0.7 million, $0.5 million and $0.5 million, respectively, of accrued interest or penalties related to unrecognized tax benefits, of which less than $0.2 million was included in the Company’s provision for income taxes in each of the years ended December 30, 2017, December 31, 2016 and December 26, 2015, respectively.

The Company’s policy is to include interest and penalties related to unrecognized tax benefits within the Company’s provision for income taxes.

The Company is potentially subject to examination by the Internal Revenue Service and the relevant state income taxing authorities under the statute of limitations for years 2002 and forward.

The Company has received assessments of tax resulting from transfer pricing examinations in India for most years in the range of fiscal years ending March 2005 through March 2014. While some of the assessment years have been settled with no change from the original tax return position, the Company intends to appeal all

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

remaining assessment years, and does not expect a significant adjustment to unrecognized tax benefits as a result of these inquiries. The Company believes that the resolution of these disputed issues will not have a material impact on our financial statements.

Included in the balance of income tax liabilities, accrued interest and penalties at December 30, 2017 is $0.4 million related to tax positions for which it is reasonably possible that the statute of limitations will expire in various jurisdictions within the next twelve months.


16.	Segment Information

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is the Company’s Chief Executive Officer (“CEO”). The Company’s CEO reviews financial information presented on a consolidated basis, accompanied by information about revenue by geographic region for purposes of allocating resources and evaluating financial performance. The Company has one business activity as a provider of optical transport networking equipment, software and services. Accordingly, the Company is considered to be in a single reporting segment and operating unit structure.

Revenue by geographic region is based on the shipping address of the customer. The following tables set forth revenue and long-lived assets by geographic region (in thousands):

17.	Employee Benefit Plan

Defined Contribution Plans

The Company has established a savings plan under Section 401(k) of the Internal Revenue Code (the “401(k) Plan”). As allowed under Section 401(k) of the Internal Revenue Code, the 401(k) Plan provides tax-deferred salary contributions for eligible U.S. employees. Employee contributions are limited to a maximum annual amount as set periodically by the Internal Revenue Code. The Company made voluntary cash contributions and matched a portion of employee contributions of $2.2 million, $2.1 million and $1.7 million for 2017, 2016 and 2015, respectively. Expenses related to the 401(k) Plan were insignificant for each of the years 2017, 2016 and 2015.

In connection with the Company's acquisition of Transmode during the third quarter of 2015, the Company has an ITP pension plan covering its Swedish employees. Commitments for old-age and survivors' pension for salaried employees in Sweden are vested through an insurance policy. Expenses related to the ITP pension plan were $3.3 million for 2017, $2.6 million for 2016 and $0.8 million from the Acquisition Date through December 26, 2015.

The Company also provides defined contribution plans in certain foreign countries where required by local statute or at the Company's discretion.

ITEM 9.	CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.


ITEM 9A.	CONTROLS AND PROCEDURES

Attached as exhibits to this Form 10-K are certifications of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), which are required in accordance with Rule 13a-14 of the Exchange Act. This “Controls and Procedures” section includes information concerning the internal controls and controls evaluation referred to in the certifications.

Evaluation of Disclosure Controls and Procedures

An evaluation was performed by our management, with the participation of our CEO and our CFO, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d -15(e) under the Exchange Act). Disclosure controls and procedures are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, our CEO and CFO concluded that, as of December 30, 2017, our disclosure controls and procedures are effective.

Inherent Limitations on Effectiveness of Controls

The Company's management, including the CEO and CFO, does not expect that our disclosure controls or our internal controls over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of the effectiveness of controls to future periods are subject to risks. Over time, controls may become inadequate because of changes in business conditions or deterioration in the degree of compliance with policies or procedures.

Changes in Internal Control over Financial Reporting

During the fourth quarter of fiscal 2017, there were no changes in the Company’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

The Company's management, with the participation of our CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP.

Management assessed the effectiveness of our internal control over financial reporting as of December 30, 2017, the end of our fiscal year. Management based its assessment on the framework established in the 2013 Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“2013 COSO framework”). Management’s assessment included evaluation of elements such as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies, and our overall control environment. This assessment is supported by testing and monitoring performed by our internal audit and finance personnel utilizing the 2013 COSO framework.

104

Based on our assessment, management has concluded that our internal control over financial reporting was effective as of the end of our fiscal year 2017 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles.

The effectiveness of our internal control over financial reporting as of the end of fiscal year 2017 has been audited by Ernst & Young, LLP, an independent registered public accounting firm, as stated in their report which is included elsewhere herein.
