The markets in which we compete are characterized by rapidly advancing technologies, frequent introduction of new solutions and aggressive selling efforts, including using significant pricing pressure to displace incumbent vendors and capture market share. Competition for sales of networking solutions, including our Networking Platforms and Platform Software and Services, is dominated by a small number of very large, multi-national companies. Our competitors include Huawei, Nokia, Cisco, Juniper Networks and ZTE. As compared to us, many of these competitors have substantially greater financial, operational and marketing resources, significantly broader product offerings and more established relationships with service providers and other customer segments. Because of their scale and resources, they may be perceived to be a better fit for the procurement or network strategies of larger network operators. We also continue to compete with several smaller but established companies that offer one or more products that compete directly or indirectly with our offerings or whose products address specific niches within the markets and customer segments we address. These competitors include Infinera, ADVA and Ribbon Communications.

Separately, the U.S. has taken steps to restrict federal agencies from doing business with, and U.S. wireless carriers from using federal subsidies to buy equipment from, Huawei and ZTE. The U.S. has also encouraged other governments to consider similar restrictions.

We have also created a new community initiative focused on promoting digital inclusion, providing greater opportunities for underserved students through access, technology and digital skills, and have undertaken joint community projects with business partners as part of this program. </span></div><div><span><br/></span></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">17</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i2d956663af5d47f9998f22a89ce8a766_7">Table of Contents</a></span></div></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:107%">Information About Our Directors and Executive Officers</span></div><div style="margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The table below sets forth certain information concerning our directors and executive officers:</span></div><div style="margin-bottom:5pt;margin-top:5pt"><table style="border-collapse:collapse;display:inline-table;vertical-align:top;width:99.707%"><tr><td style="width:1.0%"></td><td style="width:29.838%"></td><td style="width:0.1%"></td><td style="width:0.1%"></td><td style="width:0.533%"></td><td style="width:0.1%"></td><td style="width:1.0%"></td><td style="width:5.498%"></td><td style="width:0.1%"></td><td style="width:0.1%"></td><td style="width:0.533%"></td><td style="width:0.1%"></td><td style="width:1.0%"></td><td style="width:59.898%"></td><td style="width:0.1%"></td></tr><tr><td colspan="3" style="padding:2px 1pt;text-align:left;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:8pt;font-weight:400;line-height:100%">Name</span></td><td colspan="3" style="padding:0 1pt"></td><td colspan="3" style="padding:2px 1pt;text-align:center;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:8pt;font-weight:400;line-height:100%">Age</span></td><td colspan="3" style="padding:0 1pt"></td><td colspan="3" style="padding:2px 1pt;text-align:left;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:8pt;font-weight:400;line-height:100%">Position</span></td></tr><tr><td colspan="3" style="border-top:1pt solid #000000;padding:2px 1pt;text-align:left;vertical-align:top"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:100%">Patrick H.

Unprecedented actions have been taken by governments globally to try to contain the pandemic, such as travel bans and restrictions, business closures, social distancing measures, quarantines and shelter-in-place orders. This pandemic and the countermeasures to contain the virus have caused economic and financial disruptions globally, including in most of the regions in which we sell our products and services and conduct our business operations. In the second quarter of fiscal 2020, the COVID-19 pandemic adversely impacted our financial results and business operations, primarily due to supply chain disruptions, limitations on customer fulfillment activity and our level of success in obtaining new customers or selling into recent customer design wins on their original timelines. During the third </span><span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">and fourth quarters</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> of fiscal 2020, our order volumes declined significantly from previous quarters and were meaningfully below revenue during the second half of fiscal 2020 as we experienced a more cautious customer spending and customer delays in operationalizing network projects that we anticipated.

The extent and duration of ongoing workplace restrictions and limitations, particularly in sites with significant headcount, could adversely impact our operations and our ability to execute on strategic imperatives for our business. Continued restrictions on travel and limitations on interaction with customers, such as field and lab trials, may impact our sales and marketing activities, including our ability to secure new customers, to qualify and sell new products, or to grow sales with customers where or with whom we do not have a longer-standing supply relationship, such as within international markets and for our Blue Planet Automation Software and Services segment and our Packet Networking product line.</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Supply Chain</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Also as a result of the COVID-19 pandemic, we have experienced some disruption and delays in our global supply chain and related operations.

We also rely on a global component supply network involving many vendors and countries throughout the world. During the second quarter of fiscal 2020, some of our component suppliers &#8211; particularly those with facilities in China and Malaysia &#8211; experienced challenges related to COVID-19 that resulted in temporary closures or reductions of supply capacity. During the second half of fiscal 2020, we took a number of steps, some of which remain ongoing, including multi-sourcing and pre-ordering components and finished goods inventory, in an effort to reduce the impact of the adverse supply chain conditions we experienced. However, there can be no assurance that these efforts will be successful or that supply chain disruptions will not continue, or worsen, in the future. Limits on manufacturing availability or capacity, or delays in production or delivery of components or raw materials, due to COVID-related restrictions could delay or inhibit our ability to obtain supply of components and produce finished goods. If the COVID-19 pandemic worsens, it could also result in further disruptions or restrictions on our ability to source, manufacture or distribute our products, including temporary closures of our key manufacturing facilities or the facilities of our suppliers and their manufacturers. If we experience more pronounced disruptions in our operations, we may experience constrained supply that may materially adversely impact our business and results of operations in future periods. </span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%">Services and Customer Fulfillment </span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">We have experienced some disruption in our ability to provide installation, professional and fulfillment services to customers during the COVID-19 pandemic.

These conditions have also made it more challenging to execute and adversely impacted the timing of customer plans to operationalize newer projects and recent customer design wins, primarily in international markets. We expect these conditions to persist in the short-term, adversely impacting our revenue and results of operations. If any of these logistics or transportation disruptions persist for longer periods or worsen, our operations and ability to meet customer demand could be materially adversely affected. Our customers have also experienced, and may continue to experience, disruptions in their operations, which can result in delayed, reduced, or canceled orders, and increased collection risks, and which may adversely affect our results of operations.</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Demand for Products and Services</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We experienced a dynamic demand environment during fiscal 2020. During the second quarter of fiscal 2020, we experienced higher than typical orders for our products and services among a concentrated set of larger customers with whom we had existing positions as a supplier. At that time, we believed that some portion of these orders likely reflected short-term purchasing behaviors based on customer-specific considerations in the face of the pandemic, including: customer concerns about future continued availability of supply; implementation of customer business continuity actions; our desire for increased visibility into expected demand; customer consumption of their existing inventory or spare equipment; additional network capacity requirements; acceleration of capital spending; and, possibly, increased bandwidth demands being placed on networks due to the pandemic. During the third and fourth quarters of fiscal 2020, our order volumes declined significantly from previous quarters, particularly with our communications service provider and cable operator customers. With respect to these customer segments in particular, we believe that this greater capital expenditure restraint stems from the deferral or re-prioritization of certain new network initiatives and continued uncertainty associated with the impact of the pandemic and economic uncertainty upon their enterprise business segments. As a result, our quarterly order volumes were meaningfully below revenue during the second half of fiscal 2020, challenging our visibility and the outlook for our orders and revenue in future periods. In the near-term, we expect this more cautious spending environment to continue into fiscal 2021 and we expect these conditions to continue to adversely affect our order volumes and revenue in the short term. In addition, as our customers and their customers evaluate the ways in which networks and working environments will change even after the pandemic subsides, there may be long-lasting changes in customer behaviors and needs, including the end users of our customers, which may impact the demand for our products and services in the long-term. </span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Market and Economic Conditions</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our business and operating results depend significantly on general market and economic conditions.

Macroeconomic and market conditions could be adversely affected by a variety of political, economic or other factors, including long-term factors emerging from the effects of the pandemic in the United States and international markets, which could in turn adversely affect spending levels of our customers and their end users, and could create volatility or deteriorating conditions in the markets in which we operate. Due to our concentration of revenue in the United States, and the increasing concentration of our customers experienced during fiscal 2020, we would expect to incur a more significant impact from any adverse change in the capital spending environment or macroeconomic or market weakness in the United States.  </span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">As a result of continued economic uncertainty stemming from the pandemic, during the second half of fiscal 2020 we experienced a significant reduction in our order volumes, as compared to our revenue, and a reduction in our short-term outlook for our orders and revenue. We believe that ongoing concerns relating to the pandemic, and its impact on the enterprise business segments of our communications service provider and cable operator customers continue to adversely impact the velocity of business in general, with a particular impact on customer willingness and ability to initiate new network projects. We believe customers are exercising greater restraint in these projects, and more carefully prioritizing where and when to add network capacity.

As a result of these dynamics, growth rates in our addressable markets slowed and the overall market growth was flat to down in 2020 as compared to 2019, which we expect to continue to adversely impact our revenue in the near term. We expect these market dynamics, including constrained customer spending and the decreased velocity of new business execution, to persist through at least the first half of fiscal 2021.

Lack of liquidity in the capital markets, macroeconomic weakness and market volatility, including disruption caused by the COVID-19 pandemic, may increase our exposure to these credit risks. Our attempts to monitor customer payment capability and to take appropriate measures to protect ourselves may not be sufficient, and it is possible that we may have to write down or write off accounts receivable.

This market share capture has been an important contributor to our growth in recent years. However, restrictions on travel and gatherings due to COVID-19 countermeasures have impacted, and are likely to continue to impact, our interaction with customers, and the timing of certain field and lab trials. Restrictions have also impacted, and are likely to continue to impact, our ability to carry out certain sales and marketing activities, and adversely impacted our ability to secure new customers, to qualify and sell new products, and to grow sales with customers where we do not have longer-standing supply relationships, including within our Blue Planet Automation Software and Services segment and our Packet Networking product line.

A significant portion of our quarterly revenue is generated from customer orders received during that same quarter (which we refer to as &#8220;book to revenue&#8221;). Accordingly, our revenue for a particular quarter is difficult to predict, and a shortfall in expected orders in any given quarter can materially adversely affect our revenue and results of operations for that quarter or future quarterly periods.

For example, our ten largest customers contributed&#160;54.5% of our revenue for fiscal 2020 and 59.3%&#160;of&#160;our fiscal 2019&#160;revenue, and we have seen a further concentration in our orders during the second and third quarters of fiscal 2020. Historically, our largest customers by revenue principally consisted of large communications service providers. For example, AT&amp;T accounted for approximately&#160;10.6% of our revenue for fiscal 2020 and 10.9% of our revenue for fiscal 2019, and Verizon accounted for 12.9% of our revenue for fiscal 2019. As a result of efforts in recent years to diversify our business, the customer segments and geographies that comprise our customer base and top customers by revenue have changed. During fiscal 2020 and 2019, three Web-scale providers were among our top ten customers. Web-scale customers have been important contributors to our revenue through both our direct sales to them, including for data center interconnection, and their indirect impact on purchases by other network operators. Consequently, our financial results and our ability to grow our business are closely correlated with the spending of a relatively small number of customers. Our business and results of operations could be materially adversely impacted by the loss of a large customer within or outside of these customer segments as well as by reductions in spending or capital expenditure budgets, changes in network deployment plans or changes in consumption models for acquiring networking solutions by our largest customers.</span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">There have been significant horizontal and vertical consolidation activities by communications service providers and cable operators, with several such operators acquiring media and content companies.

Several of these, including AT&amp;T, have announced various initiatives that seek to modify how they purchase networking infrastructure or reduce capital expenditures on network infrastructure in future periods that may adversely affect our results of operations. Web-scale providers are also under consumer and government scrutiny and have been the subject of regulatory and other government actions, including antitrust investigations. There can be no assurance that these government actions will not adversely impact the network spending, procurement strategies, or business practices of our Web-scale customers in a manner adverse to us. Our business and results of operations could be materially adversely affected by these factors and other market, industry or competitive dynamics adversely impacting our customers.</span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In addition, the negative effects of the COVID-19 pandemic on global economic conditions have affected and may continue to affect the network spending, procurement strategies, or business practices of our largest customers. For example, our service provider customers rely in part upon the sale of services to consumers and enterprises, including those in the retail, entertainment, and travel industries, which have been acutely impacted by the negative economic effects of the COVID-19 pandemic. Similarly, certain of our Web-scale customers have business models that heavily rely upon advertising revenue from enterprises, including those in industries acutely affected by the COVID-19 pandemic. If any of our large customers experience a loss in revenue due to the impact of COVID-19 on their consumer or enterprise customers, they may reduce capital spending on networking projects, including data centers, which could materially adversely affect our business and results of operations.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">We face intense competition that could hurt our sales and results of operations, and we expect the competitive landscape in which we operate to continue to broaden to include additional solutions providers.</span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We face an intense competitive market for sales of communications networking equipment, software and services.

As a result of the COVID-19 pandemic, technology preferences, customer demand and the markets for our solutions may move in directions that we had not anticipated. As a general matter, there is a significant possibility&#160;that some of our development decisions, including significant expenditures on acquisitions, research and development, or investments in technologies, will not meet our expectations, and that our investment in some projects will be unprofitable. There is also a possibility that we may miss a market opportunity because we failed to invest or invested too late in a technology, product or enhancement sought by our customers or the markets into which we sell. Changes in market demand or investment priorities may also cause us to discontinue existing or planned development for new products or features, which can have a disruptive effect on&#160;our relationships with customers. In addition, failure to develop, on a cost-effective basis, innovative new or enhanced solutions that are attractive to customers and profitable to us could have a material adverse effect on our business, results of operations, financial condition and cash flows.</span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">We have no guaranteed purchases and regularly have to re-win business for existing customers.</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Generally, our customer contracts do not require customers to purchase any minimum or guaranteed volumes, and we conduct sales through framework contracts under which customers place purchase orders for which they often have the right to modify or cancel. We must regularly compete for and win business with existing customers across all of our customer segments. In addition, Web-scale providers tend to operate on shorter procurement cycles than some of our traditional customers, which can require us to compete to re-win business with these customers more frequently than required with other customers segments. As such, there is no assurance that our incumbency will be maintained at any given customer or that our revenue levels from a customer in a particular period can be achieved in future periods. Customer spending levels can be unpredictable, and our sales to any customer could significantly decrease or cease at any time. </span></div><div style="text-indent:18pt"><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Network equipment sales often involve lengthy sales cycles and protracted contract negotiations that may require us to agree to commercial terms or conditions that negatively affect pricing, risk allocation, payment and the timing of revenue recognition.</span></div><div><span><br/></span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our sales efforts, particularly with communications service providers, Web-scale providers and other large customers, often involve lengthy sales cycles. These selling efforts often involve a significant commitment of time and resources that may include extensive product testing, laboratory or network certification, network or region-specific product certification and homologation requirements for deployment in networks. Even after a customer awards its business to us or decides to purchase our solutions, the length of time before deployment can vary depending on the customer&#8217;s schedule, site readiness, the size of the network deployment, the degree of custom configuration required and other factors. Additionally, these sales also often involve protracted and sometimes difficult contract negotiations in which we may deem it necessary to agree to unfavorable contractual or commercial terms that adversely affect pricing, expose us to penalties for delays or non-performance and require us to assume a disproportionate amount of risk.

We have a limited history in commercializing and selling these software solutions and have only recently acquired certain elements of our Blue Planet portfolio. Moreover, the market and competitive landscape for these solutions is dynamic, and it is difficult to predict important trends, including the potential growth, if any, of this market.

We refer to these different approaches as &#8220;consumption models.&#8221; These consumption models can include: the traditional systems procurement of fully integrated solutions including hardware, software and services from the same vendor; the procurement of a fully integrated hardware solution from one vendor with the separate use of a network operator&#8217;s own SDN-based controller; the procurement of an integrated photonic line system with open interfaces from one vendor and the separate or &#8220;disaggregated&#8221; procurement of modem technology from a different vendor; or the development and use of published reference designs and open source specifications for the procurement of &#8220;white box&#8221; hardware to be used with open source software. In parallel, network operators are also exploring procurement alternatives for software solutions, ranging from integrated and proprietary software platforms to fully open source software. </span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We believe that network operators will continue to consider a variety of different consumption models. Many of these approaches are in their very early stages of development and evaluation, and the types of models and their levels of adoption will depend in significant part on the nature of the circumstances and strategies of particular network operators. Among our customers, AT&amp;T, certain Web-scale providers and others are pursuing network strategies that emphasize enhanced software programmability, management and control of networks, and deployment of &#8220;white box&#8221; hardware. A number of network operators are pursuing the deployment of smaller form factor, pluggable modem technology, particularly within switching and routing solutions, as an alternative to integrated optical networking platforms. Other network operators, including certain of our Web-scale customers, are playing a leading role in the transition to software-defined networking or the standardization of communications network solutions. We believe that the potential for different approaches to the procurement of networking infrastructure will require network operators and vendors to evolve and broaden their existing solutions and commercial models over time. Adoption of a range of consumption models may also alter and broaden our competitive landscape to include other technology vendors, including routing vendors, component vendors and IT software vendors. If we are unable to adapt our business to these new consumption models and offer attractive solutions and commercial models that accommodate the range of consumption models ultimately adopted by our customers or within our markets, our business, competitive position and results of operations could be adversely affected.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Our go-to-market activities and the distribution of our WaveLogic coherent modem technology within the merchant modem market could expose us to increased or new forms of competition, or adversely affect our existing systems business and results of operations.</span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We recently entered the merchant modem market to monetize our coherent optical technology, expand our addressable market and address a range of customer consumption models for networking solutions.

In a number of cases these suppliers may require longer lead times for fulfillment than we have with our customers. Thus, our practice of buying inventory based on forecasted demand exposes us to the risk that our customers ultimately may not order the products we have forecast or will purchase fewer products than forecast. As a result, we may purchase inventory in anticipation of sales that ultimately do not occur. We regularly incur, on a quarterly basis, expense provisions against excess or obsolete inventory and may have difficulty forecasting inventory and customer spending. Moreover, our customer purchase agreements generally do not include any minimum purchase commitment and customers often have the right to modify, reduce or cancel purchase quantities. Our products are highly configurable, and certain new products have overlapping feature sets or application with existing products. Accordingly, it is increasingly possible that customers may forgo purchases of certain products we have inventoried in favor of a similar or newer product. We may also be exposed to inventory write-offs as a result of certain supply chain initiatives, including consolidation and transfer of key manufacturing activities. If we are required to write off or write down a significant amount of inventory, our results of operations for the applicable period would be materially adversely affected. Conversely, if we underestimate our demand, our contract manufacturers and component suppliers may have inadequate time, materials, or components required to manufacture our products. This could increase costs or delay or interrupt manufacturing of our products, resulting in delays in shipments and deferral or loss of revenues and could adversely impact customer satisfaction.

Due to our global presence, a significant percentage of our revenue, operating expense and assets and liabilities are non-U.S. Dollar denominated and therefore subject to foreign currency fluctuation. We face exposure to currency exchange rates as a result of the growth in our non-U.S. Dollar denominated operating expense in Canada, Europe, Asia and Latin America. An increase in the value of the U.S. Dollar could increase the real cost to our customers of our products in those markets outside the United States where we sell in Dollars, and a weakened Dollar could increase the cost of local operating expenses and procurement of materials or service that we purchase in foreign currencies. From time to time, we hedge against currency exposure associated with anticipated foreign currency cash flows or assets and liabilities denominated in foreign currency. Such attempts to offset the impact of currency fluctuations are costly, and we cannot hedge against all foreign exchange rate volatility. Losses associated with these hedging instruments and the adverse effect of foreign currency exchange rate fluctuation may negatively affect our results of operations. </span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:115%">Risks Related to Our Operations and Reliance on Third Parties</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:115%">We may experience delays in the development and production of our products that may negatively affect our competitive position and business.</span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our hardware and software networking solutions, including our coherent optical chipset, our WaveLogic modem technology and the components thereof, are based on complex technology, and we can experience unanticipated delays in developing, manufacturing and introducing these solutions to market.

In May 2019, the U.S. Department of Commerce amended the Export Administration Regulations by adding Huawei Technologies Co., Ltd. and certain affiliates to the &#8220;Entity List&#8221; for actions contrary to the national security and foreign policy interests of the United States, imposing significant new restrictions on export, reexport and transfer of U.S. regulated technologies and products to Huawei. In August 2020, the U.S. Department of Commerce added additional Huawei affiliates to the Entity List, confirmed the expiration of a temporary general license applicable to Huawei and amended the foreign direct product rule in a manner that represents a significant expansion of its application to Huawei. Several of our third-party component suppliers, including certain sole and limited source suppliers, sell products to Huawei and, in some cases, Huawei is a significant customer for such suppliers. At this time, there can be no assurance regarding the scope or duration of these restrictions, including the foreign direct product rule, or further actions imposed on Huawei, and any future impact on our suppliers.

Competition to attract and retain highly skilled technical, engineering and other personnel with experience in our industry is intense, and our employees have been the subject of targeted hiring by our competitors. Competition is particularly intense in certain jurisdictions where we have research and development centers, including the Silicon Valley area of northern California, and we may experience difficulty retaining and motivating existing employees and attracting qualified personnel to fill key positions. There can be no assurance that the programs, initiatives, rewards and recognition that are part of our annual &#8220;people strategy&#8221; will be successful in attracting and retaining the talent necessary to execute on our business plans. Because we rely on equity awards as a significant component of compensation, particularly for our executive team, a lack of positive performance in our stock price, reduced grant levels, or changes to our compensation program may adversely affect our ability to attract and retain key employees. In addition, none of our executive officers is bound by an employment agreement for any specific term. We have a number of workforce planning initiatives underway and our failure to manage these programs effectively could result in the loss of key personnel. Similarly, the failure to properly manage the necessary knowledge transfer required from these employee transitions could impact our ability to maintain industry and innovation leadership. The loss of members of our management team or other key personnel, including due to COVID-19, could be disruptive to our business and, were it necessary, it could be difficult to replace such individuals. If we are unable to attract and retain qualified personnel, we may be unable to manage our business effectively, and our operations and financial results could suffer. </span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In addition, a number of our team members are foreign nationals who rely on visas or work-entry permits in order to legally work in the United States and other countries. Changes in government policy and global events such as pandemics may interfere with our ability to hire or retain personnel who require these visas or entry permits. For example, in response to the COVID-19 pandemic, the United States suspended entry of certain foreign nationals, which could impact our ability to attract, develop, integrate and retain highly skilled employees with appropriate qualifications from other countries. Numerous U.S. Embassies have suspended the processing of new visa applications for a period of time during 2020 due to COVID-19 related concerns impacting Embassy operations and staffing. In addition, on April 22, 2020, in a stated effort to protect Americans from competition from foreign workers during the COVID-19 pandemic, the U.S. President signed an executive order to pause for 60 days the issuance of immigrant visas issued at U.S. embassies to enter the United States, and on June 22, 2020 extended the pause and added restrictions on the issuance of several categories of temporary visas through at least the end of the calendar year, including restrictions on new H-1B visas for certain skilled workers and new L-1 visas for intracompany transfers of executives/managers and specialized knowledge persons such as those employed in information technology and engineering, subject to certain exceptions. Additional changes in immigration policy, including the implementation of restrictive interpretations by the U.S. Citizenship and Immigration Services of regulatory requirements for H-1B, L-1 and other U.S. work visa categories, may also adversely affect our ability to hire or retain key talent, which could have an impact on our business operations.</span></div><div style="margin-bottom:10pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:115%">Risks Related to Intellectual Property, Litigation, Regulation and Government Policy</span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Our intellectual property rights may be difficult and costly to enforce.</span></div><div><span><br/></span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We generally rely on a combination of patents, copyrights, trademarks and trade secret laws to establish and maintain proprietary rights in our products and technology.

This decision, which was reaffirmed and updated in October 2020 following a partial remand and reversal by the U.S. Court of Appeals for the District of Columbia Circuit, repeals net neutrality regulations that prohibit blocking, degrading or prioritizing certain types of internet traffic and restores the light touch regulatory treatment of broadband service in place prior to 2015. Although the FCC&#8217;s initial decision has preempted state jurisdiction on net neutrality, the U.S. Court of Appeals decision vacated the specific preemption provision in the 2017 order. At least two states, Montana and New York, took executive action directed at reinstating aspects of the FCC&#8217;s 2015 order even prior to the U.S. Court of Appeals decision. In addition, in September 2018, California passed legislation that seeks to reestablish net neutrality. Changes in regulatory requirements or uncertainty associated with the regulatory environment could delay or serve as a disincentive to investment in network infrastructures by network operators, which could adversely affect the sale of our products and services. Similarly, changes in regulatory tariff requirements or other regulations relating to pricing or terms of carriage on communications networks could slow the development or expansion of network infrastructures and adversely affect our business, operating results, and financial condition.</span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In October 2019, the Supreme Court of India ruled against an industry group of India service providers in a long-standing dispute over the calculation of license and other regulatory fees owing to India&#8217;s Department of Telecommunications.

The terms of the withdrawal were subject to contentious negotiations that created significant uncertainty about the future relationship between the UK and the EU, and negotiations about the future trading relationship between the UK and EU continue during a transition period that expires on December 31, 2020. It is possible that the level of economic activity in this region will be adversely impacted by Brexit and that there will be increased regulatory and legal complexities, including those relating to tax, trade, security and employees. Such changes could be costly and potentially disruptive to our operations and business relationships in these markets. Economic uncertainty related to Brexit, including volatility in global stock markets and currency exchange rates, could adversely impact our business. In addition, there is a risk that the UK and the EU will fail to reach any agreement during the transition period on the terms of their future trading relationship, which has resulted in additional uncertainty and could lead to further costs and disruptions.

For example, our operations and financial results may be negatively affected by environmental regulations, such as the Waste Electrical and Electronic Equipment (WEEE) and Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (RoHS) that have been adopted by the EU. Compliance with these and similar environmental regulations may increase our cost of designing, manufacturing, selling and removing our products.

In response to the COVID-19 pandemic, we have prioritized the safety of our employees and business partners, while continuing to support the needs of our customers and communities during this unprecedented period. We have also implemented business continuity plans designed to minimize potential business disruption from the COVID-19 pandemic and to protect our supply chain and customer fulfillment and support operations. </span></div><div style="text-indent:18pt"><span><br/></span></div><div style="margin-bottom:8pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%">Demand for Products &amp; Services</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">.</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%"> </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">Since the outset of the COVID-19 pandemic, we have experienced a dynamic demand environment, as reflected in significant changes in our order volumes and revenue. During the second quarter of fiscal 2020, we experienced higher than typical orders for our products and services among a concentrated set of larger customers with whom we had an existing position as a supplier. At that time, we believed that some portion of these orders likely reflected short-term purchasing behaviors based on customer-specific considerations in the face of the pandemic, including: customer concerns about future continued availability of supply; implementation of customer business continuity actions; our enhanced efforts to obtain increased visibility into expected demand; customer consumption of their existing inventory or spare equipment; additional network capacity requirements; acceleration of capital spending; and, possibly, increased bandwidth demands being placed on networks due to the pandemic. During the third and fourth quarters of fiscal 2020, our order volumes declined significantly from the level achieved in the second quarter of fiscal 2020, particularly among our communications service provider customers and cable operator customers. We believe that this greater capital expenditure restraint stems from the deferral or re-prioritization of certain new network initiatives and continued uncertainty associated with the impact of the pandemic and economic uncertainty upon their enterprise business segments. As a result, our order volumes were meaningfully below revenue during the second half of fiscal 2020, challenging our visibility and the outlook for orders and revenue in future </span></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">47</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i2d956663af5d47f9998f22a89ce8a766_7">Table of Contents</a></span></div></div><div style="margin-bottom:8pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">periods. We expect this more cautious spending environment to continue into fiscal 2021 and expect these conditions to continue to adversely affect our order volumes and revenue in the short term. Over the longer term, we continue to believe that the unique and increased demands placed on network infrastructures as a result of the COVID-19 pandemic, and the related increase in remote working worldwide, have accelerated certain trends, including cloud network adoption, networking resilience and flexibility, and enhanced network automation. We believe that we are well positioned competitively to capitalize on the longer-term opportunities that we expect to be presented by these dynamics. </span></div><div style="margin-bottom:8pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%">Supply Chain</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">. During the second quarter of fiscal 2020, some of our component suppliers &#8211; particularly those with facilities in China and Malaysia &#8211; experienced challenges related to COVID-19 that resulted in temporary closures or reductions of supply capacity. Although in many cases we were able to overcome these conditions through execution of our mitigation planning, supply chain disruptions negatively impacted our revenue for the second quarter of fiscal 2020. During the second half of fiscal 2020, we took a number of steps, some of which remain ongoing, including multi-sourcing and pre-ordering components and finished goods inventory, in an effort to reduce the impact of the adverse supply chain conditions that we experienced. As a result of these actions, and generally improved conditions with our suppliers or the geographies in which they operate, supply chain related challenges to our operations abated in the third and fourth quarters of fiscal 2020 and were not material to revenue. However, there can be no assurance that supply chain disruptions related to COVID-19 will not continue, or worsen, in the future. </span></div><div style="margin-bottom:8pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%">Services and Customer Fulfillment.</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"> We have experienced some disruption in our ability to provide installation, professional and fulfillment services to customers due to site access limitations, limited customer availability, project delays or re-prioritization by customers, and travel bans or restrictions on movement or gatherings. These conditions, which adversely impacted revenue in the second quarter of fiscal 2020, have also adversely impacted the timing of customer plans for newer network projects and our ability to operationalize recent customer design wins, primarily in international markets. We expect these conditions to persist in the short-term and, as a result, to continue to adversely impact our revenue and results of operations. We continue to take steps and work with customers to ensure their business needs are supported, while protecting the health and safety of our employees, customers and business partners. However, should restrictions or disruptions persist or worsen, including any reduced availability of air transport, port closures, or increased border controls or closures, our business, operations and ability to meet customer demand could be materially adversely affected. </span></div><div style="margin-bottom:8pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%">Sales &amp; Marketing. </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">The competitive nature of our business depends on our ability to conduct sales and marketing activities with our customers. For instance, in the past few years, our ability to be first to market with leading networking solutions, and to conduct sales and marketing activities around these new technology offerings, has had a significant impact on our revenue and growth. In the first half of fiscal 2020, we were the first to market with 800 gigabit technology with our fifth-generation WaveLogic&#174; coherent modem technology. Restrictions on travel due to COVID-19 and limitations on interactions with customers, such as field and lab trials, have negatively impacted our ability to carry out certain sales and marketing activities, including our ability to secure new customers, to qualify and sell new products, and to grow sales with customers. This is particularly the case where we do not have longer-standing supply relationships, such as within international markets and for our Blue Planet Automation Software and Services segment and our Packet Networking product line. We believe customers are exercising greater restraint in networking projects, including data centers, and are also more carefully prioritizing where and when to add network capacity. Delays in operationalizing new network projects that we anticipated occurring on their original timelines adversely affected our revenue during fiscal 2020. Conversely, our recent gross margin performance has benefited from these dynamics, with a larger percentage of our revenue comprised of existing business, as compared to new design wins and early in life projects, which tend to have lower margins.</span></div><div style="margin-bottom:8pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%">Market Growth &amp; Conditions.</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"> We believe that ongoing concerns relating to the pandemic, and its impact on the enterprise business segments of our communications service provider and cable operator customers, continue to adversely impact the velocity of business in general, with a particular impact on customer willingness and ability to initiate new network projects. For example, our service provider customers rely in part upon the sale of services to consumers and enterprises, including those in the retail, entertainment, and travel industries, which have been acutely impacted by the negative economic effects of the COVID-19 pandemic. Similarly, certain of our Web-scale customers have business models that heavily rely upon advertising revenue from enterprises, including those in industries acutely affected by the COVID-19 pandemic. As a result of these dynamics, the growth rates in our addressable markets slowed during fiscal 2020 as compared to fiscal 2019, which adversely impacted our revenue in fiscal 2020. We expect these market dynamics, including constrained customer spending and the decreased velocity of new business execution, to persist into fiscal 2021.</span></div><div style="margin-bottom:8pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%">Liquidity &amp; Balance Sheet.</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"> As of the end of the fourth quarter of fiscal 2020, we had $1.3 billion in cash and investments. We believe our strong liquidity and balance sheet position is an important competitive differentiator at this time. It enables us to continue to invest in innovation, ensure a strong inventory position to support customers and provide for working capital needs. We regularly evaluate our liquidity position, debt obligations, and anticipated cash needs to fund our operating or investment plans, and may consider capital raising and other market opportunities that may be available to us.

Emerging services and applications, including 5G mobile communications, Fiber Deep and the Internet of Things, are further impacting or expected to impact wireline network infrastructures, particularly at the edge of networks, where increased computing power and automation are required to provide the quality of experience demanded by end users. Many network operators are under pressure to constrain their capital expenditure budgets, as they cannot grow their network spending at the rate of bandwidth growth, including due to their business models. To address these growing service demands and better manage network cost, many network operators are looking to adopt next-generation infrastructures that are more programmable and better capable of leveraging data for network insight, analytics and automation. Other network operators are pursuing a diverse range of consumption models in their design and procurement of network infrastructure solutions. Our Adaptive Network vision and our business strategy to capitalize on these changing market dynamics include the initiatives set forth in the &#8220;Strategy&#8221; section of the description of our business in Item 1 of Part 1 of this annual report.</span></div><div style="margin-bottom:8pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Business Diversification</span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">A key element of our strategy is to continue to diversify our solutions offerings, customer base and geographic reach to address fast-growing applications and markets. We believe that the continued diversification of our business is important to address the dynamic industry environment in which we operate, to grow our business, and to better withstand potential slowdowns adversely affecting particular geographies, markets or customer segments. In recent fiscal years prior to fiscal 2020, our diversification and global scale were key contributors to our strong revenue growth. In fiscal 2020, we believe this diversification allowed us to maintain a greater degree of stability and allowed us to remain resilient despite the impact of the COVID-19 pandemic on any particular geography, segment or customer account. </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Investment in Technology Innovation</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">We believe that our investment capacity and our efforts to push the pace of innovation in our markets, and to provide market-leading offerings ahead of our competitors, are important competitive differentiators in our markets. Keeping pace with the market&#8217;s demand for technology innovation requires considerable research and development investment capacity and expenditures, and research and development spending represented 45.4% of our operating expenses in fiscal 2020. During fiscal 2020, we invested $529.9 million in research and development activities, a decrease of approximately 3.3% compared to fiscal 2019, primarily due to the impact of COVID-19. However, we expect our operating expenses to increase in fiscal 2021, in part to support additional investment in research and development activities. We believe that remaining competitive in our addressable geographies, markets, and customer segments depends on our continued significant investment in innovation and our ability to offer leading solutions that enable adoption of next-generation network infrastructures and evolving consumption models for networking solutions.</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Optical and Packet Infrastructure Technology</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">. We are focused on growing our optical and packet infrastructure business by addressing fast-growing markets and applications, including data center interconnection, packet aggregation and routing and submarine networks. In fiscal 2020, we brought to market our fifth-generation coherent modem technology capable of delivering 800 gigabits of capacity per second over a single wavelength, and, during 2021, we expect to bring to market our footprint-optimized WaveLogic 5 Nano 100G-400G coherent pluggable transceivers. We are also developing Packet Networking solutions with enhanced IP/Ethernet capabilities to expand our addressable market into additional next generation metro and access applications including packet routing, aggregation and switching, 5G cross-haul, Fiber Deep, and edge computing. In fiscal 2020, we also announced the future addition of several new routing platforms to support the demands of mobile xHaul (fronthaul, midhaul and backhaul) transport, which we expect to make available in fiscal 2021. </span></div><div><span><br/></span></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">49</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i2d956663af5d47f9998f22a89ce8a766_7">Table of Contents</a></span></div></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Blue Planet Automation Software. </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We have continued to pursue both organic investments and acquisition opportunities to expand our Blue Planet Automation Software and Services portfolio and business. On&#160;November 4, 2019, we acquired privately held Centina Systems, Inc., a provider of service assurance analytics and network performance management solutions. The acquisition of Centina is intended to accelerate Blue Planet&#8217;s software strategy of providing closed loop, intelligent automation solutions that help communications service providers analyze network conditions, traffic demands, and resource availability, and determine the best placement of traffic for optimal service quality and resource utilization.&#160;See Note 3 to our Consolidated Financial Statements included in Item 8 of Part II of this report for more information on this acquisition and the related accounting. In addition, we have enhanced our Blue Planet Intelligent Automation software portfolio for 5G automation applications, including vendor-agnostic network slicing features and dynamic planning capabilities that are intended to better enable mobile network operators to deliver 5G mobile services. </span></div><div style="text-indent:18pt"><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Fiscal Year-End Backlog</span></div><div><span><br/></span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Generally, we make sales pursuant to purchase orders placed by customers under framework agreements that govern the general commercial terms and conditions of the sale of our products and services. These agreements do not obligate customers to purchase any minimum or guaranteed order quantities. Moreover, we are periodically awarded business for new network opportunities or network upgrades following a selection process. In calculating backlog, we only include (i) customer purchase orders for products that have not been shipped and for services that have not yet been performed; and (ii) customer orders relating to products that have been delivered and services that have been performed, but are awaiting customer acceptance under the applicable contract terms. Generally, our customers may cancel or change their orders with limited advance notice, or they may decide not to accept our products and services, although instances of both cancellation and non-acceptance are rare. Backlog may be fulfilled several quarters following receipt of a purchase order, or in the case of certain service obligations, may relate to multi-year support period. As a result, backlog should not necessarily be viewed as an accurate indicator of future revenue for any particular period.</span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our backlog was $1.19&#160;billion as of October&#160;31, 2020 as compared to $1.21&#160;billion as of November&#160;2, 2019. Backlog includes product and service orders from commercial and government customers combined. Backlog at October&#160;31, 2020 includes approximately $193.5&#160;million primarily related to orders for products and maintenance and support services that are not expected to be filled or performed within fiscal 2021. Because backlog can be defined in different ways by different companies, our presentation of backlog may not be comparable with figures presented by other companies in our industry.</span></div><div style="margin-top:6pt;text-indent:15.75pt"><span><br/></span></div><div id="i2d956663af5d47f9998f22a89ce8a766_43"></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Consolidated Results of Operations</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">A discussion regarding our financial condition and results of operations for fiscal 2020 compared to fiscal 2019 is presented below.

During fiscal 2020 as compared to fiscal 2019, the U.S. Dollar fluctuated against these and other currencies. Consequently, our revenue reported in U.S. Dollars was slightly reduced by approximately $13.5 million, or 0.4%, as compared to fiscal 2019 due to fluctuations in foreign currency.

The combination of this regular technology-driven price compression, price competition in our markets and ongoing customer efforts to manage network costs can impact our growth rates and requires that we increase our volume of product shipments to maintain and grow revenue.</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Cost of Goods Sold and Gross Profit</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Product cost of goods sold consists primarily of amounts paid to third-party contract manufacturers, component costs, employee-related costs and overhead, shipping and logistics costs associated with manufacturing-related operations, warranty and other contractual obligations, royalties, license fees, amortization of intangible assets, cost of excess and obsolete inventory and, when applicable, estimated losses on committed customer contracts. </span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Services cost of goods sold consists primarily of direct and third-party costs associated with our provision of services including installation, deployment, maintenance support, consulting and training activities, and, when applicable, estimated losses on committed customer contracts.

Our gross margin can fluctuate and be adversely impacted depending on our revenue concentration within a particular segment, product line, geography, or customer, including our success in selling software in a particular period. Our gross margin remains highly dependent on our continued ability to drive product cost reductions relative to the price erosion that we regularly encounter in our markets. Moreover, we are often required to compete with aggressive pricing and commercial terms, and, to secure business with new and existing customers, we may agree to pricing or other unfavorable commercial terms that adversely affect our gross margin. Success in taking share and winning new business can result in additional pressure on gross margin from these pricing dynamics and the early stages of these network deployments. Early stages of new network builds also often include an increased concentration of lower margin &#8220;common&#8221; equipment, photonics sales and installation services, with the intent to improve margin as we sell channel cards and maintenance services to customers adding capacity or services to their networks. Gross margin can be impacted by technology-based price compression and the introduction or substitution of new platforms with improved price for performance as compared to existing solutions that carry higher margins. Gross margin can also be impacted by changes in expense for excess and obsolete inventory and warranty obligations.</span></div><div style="text-indent:18pt"><span><br/></span></div><div

improvement in our service margin. Due to the impact of COVID-19 and related restrictions on sales and marketing activities described in &#8220;Overview&#8221; above, during the last three quarters of fiscal 2020, a higher proportion of our revenue consisted of sales of existing technology offerings deployed in the networks of existing customers, as compared to sales to new customers, early stage network deployments for recent design wins, or the introduction of new platforms, which tend to carry lower margins. We expect our gross margins to reduce from these elevated short-term levels as some of the pandemic&#8217;s impacts on new business lessen and our overall revenue resumes a more typical composition of revenue from existing and new business. Our efforts to expand our customer base or market share have in prior periods adversely affected our gross margin depending upon our mix of revenues from new wins or early stage deployments in a particular period. </span></div><div style="margin-top:6pt;padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Times New

We principally use the ABL Credit Facility to support the issuance of letters of credit that arise in the ordinary course of our business and thereby to reduce our use of cash required to collateralize these instruments. As of October&#160;31, 2020, letters of credit totaling $83.0 million were outstanding under our ABL Credit Facility.

These purchase orders under framework agreements are used to determine the identification of the contract or contracts with this customer. Purchase orders typically include the description, quantity, and price of each product or service purchased. Purchase orders may include one-line bundled pricing for both products and services. Accordingly, purchase orders can include various combinations of products and services that are generally distinct and accounted for as separate performance obligations. We evaluate each promised product and service offering to determine whether it represents a distinct performance obligation. In doing so, we consider, among other things, customary business practices, whether the customer can benefit from the product or service on its own or together with other resources that are readily available, and whether our commitment to transfer the product or service to the customer is separately identifiable from other obligations in the purchase order. For transactions where we deliver the product or services, we are typically the principal and record revenue and costs of goods sold on a gross basis.</span></div><div style="text-indent:13.5pt"><span><br/></span></div><div style="margin-top:3pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Purchase orders are invoiced based on the terms set forth either in the purchase order or the framework agreement, as applicable. Generally, sales of products and software licenses are invoiced upon shipment or delivery. Maintenance and software subscription services are invoiced quarterly or annually in advance of the service term. Our other service offerings are generally invoiced upon completion of the service. Payment terms and cash received typically range from 30 to 90 days from the invoicing date. Historically, we have not provided any material financing arrangements to its customers. As a practical expedient, we do not adjust the amount of consideration we will receive for the effects of a significant financing component as we expect, at contract inception, that the period between our transfer of the products or services to the customer, and customer payment for the products or services will be one year or less. Shipping and handling fees invoiced to customers are included in revenue, with the associated expense included in product cost of goods sold.

All of the assets acquired, liabilities assumed, contractual contingencies and contingent consideration are recognized at their fair value as of the acquisition date. The excess of the purchase price over the estimated fair values of the net tangible and net intangible assets acquired is recorded as goodwill. The application of the purchase method of accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed in order to allocate purchase price consideration properly between assets that are depreciated and amortized from goodwill. These assumptions and estimates include a market participant&#8217;s use of the asset and the appropriate discount rates for a market participant. Our estimates are based on historical experience, information obtained from the management of the acquired companies and, when appropriate, include assistance from independent third-party appraisal firms. Our significant assumptions and estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted-average cost of capital, and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable. In addition, unanticipated events and circumstances may occur that may affect the accuracy or validity of such estimates. During fiscal 2018, we completed the Packet Design acquisition for a purchase price of $41.1 million and the DonRiver acquisition for a purchase price of $54.2 million, including a contingent consideration component. During fiscal 2020, we completed the Centina acquisition for a purchase price of $34.0 million.

Our outstanding restricted stock unit awards are subject to service-based vesting conditions and/or performance-based vesting conditions. We recognize the estimated fair value of service-based awards as share-based expense ratably over the vesting period on a straight-line basis. Awards with performance-based vesting conditions require the achievement of certain financial or other performance criteria or targets as a condition to the vesting, or acceleration of vesting. We recognize the estimated fair value of performance-based awards as share-based expense over the performance period, using graded vesting, which considers each performance period or tranche separately, based on our determination of whether it is probable that the performance targets will be achieved. At the end of each reporting period, we reassess the probability of achieving the performance targets and the performance period required to meet those targets, and the expense is adjusted accordingly. Determining whether the performance targets will be achieved involves judgment, and the estimate of expense may be revised periodically based on changes in the probability of achieving the performance targets. Revisions are reflected in the period in which the estimate is changed. If any performance goals are not met, no compensation cost is ultimately recognized against that goal and, to the extent previously recognized, compensation cost is reversed. </span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Share-based compensation expense is taken into account based on awards granted.

Inventory write downs are a component of our product cost of goods sold. Upon recognition of the write down, a new lower cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. In an effort to limit our exposure to delivery delays and to satisfy customer needs, we purchase inventory based on forecasted sales across our product lines. In addition, part of our research and development strategy is to promote the convergence of similar features and functionalities across our product lines.

The goodwill from these acquisitions is primarily related to expected synergies. Goodwill is the excess of the purchase price over the fair values assigned to the net assets acquired in a business combination. We test goodwill for impairment on an annual basis, which we have determined to be as of the last business day of fiscal September each year. We also test goodwill for impairment between annual tests if an event occurs or circumstances change that would, more likely than not, reduce the fair value of the reporting unit below its carrying value.</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We test goodwill impairment by comparing the fair value of the reporting unit with the unit&#8217;s carrying amount, including goodwill. Goodwill is allocated to reporting units based on relative fair value using a discounted cash flow model. If this test indicates that the fair value is less than the carrying value, then an impairment loss is recognized limited to the total amount of goodwill allocated to that reporting unit. A non-cash goodwill impairment charge would have the effect of decreasing earnings or increasing losses in such period. If we are required to take a substantial impairment charge, our operating results would be materially adversely affected in such period.

In evaluating whether a valuation allowance is required under such rules, we consider all available positive and negative evidence, including prior operating results, the nature and reason for any losses, our forecast of future taxable income, utilization of tax planning strategies, and the dates on which any deferred tax assets are expected to expire. These assumptions and estimates require a significant amount of judgment and are made based on current and projected circumstances and conditions. </span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Quarterly,&#160;we perform an analysis to determine the likelihood of realizing our deferred tax assets and whether sufficient evidence exists to support reversal of all or a portion of the valuation allowance.&#160;The valuation allowance balances at October&#160;31, 2020 and November&#160;2, 2019 were $151.4 million and $136.0 million, respectively.&#160;The corresponding net deferred tax assets were $647.8 million and $714.9 million, respectively. We will continue to evaluate future financial performance to determine whether such performance is both sustained and significant enough to provide sufficient evidence to support reversal of all or a portion of the remaining valuation allowance. The value of our net deferred tax asset may be subject to change in the future, depending on our generation or projections of future taxable income, as well as changes in tax policy or our tax planning strategy.

Our products are generally covered by a warranty for periods ranging from one to five years. We accrue for warranty costs as part of our cost of goods sold based on associated material costs, technical support labor costs and associated overhead. Material cost is estimated based primarily on historical trends in the volume of product returns within the warranty period and the cost to repair or replace the equipment. Technical support labor cost is estimated based primarily on historical trends and the cost to support the customer cases within the warranty period. The provision for product warranties, net of adjustments for previous years&#8217; provisions, was $22.4 million, $23.1 million and $21.0 million for fiscal 2020, 2019 and 2018 respectively.&#160;The provision for warranty claims may fluctuate on a quarterly basis depending on the mix of products and customers in that period. If actual product failure rates, material replacement costs, service or labor costs differ from our estimates, revisions to the estimated warranty provision would be required. See Note 14 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report. An increase in warranty claims or the related costs associated with satisfying our warranty obligations could increase our cost of sales and negatively affect our gross margin.</span></div><div style="text-indent:13.5pt"><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Effects of Recent Accounting Pronouncements</span></div><div style="text-indent:13.5pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">See Note 1 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report for information relating to our discussion of the effects of recent accounting pronouncements. </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Unaudited Quarterly Results of Operations</span></div><div style="text-align:justify;text-indent:13.5pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The tables below (in thousands, except per share data) set forth the operating results in our consolidated statements of operations for each of the eight quarters in the period ended October&#160;31, 2020. Our revenue can fluctuate from quarter to quarter as a result of a number of factors, including changes in customer spending levels or networking strategies, order timing and volume, backlog levels, timing of revenue recognition and other competitive dynamics. As our business has evolved, including the sales of our solutions to meet the &#8220;on-demand&#8221; service requirements of both our customers and their end users, the amount of quarterly revenue that we recognize in a quarter from customer orders received in that same quarter (which we </span></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">64</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i2d956663af5d47f9998f22a89ce8a766_7">Table of Contents</a></span></div></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">refer to as &#8220;book to revenue&#8221;) has increased as compared to our historical periods.

See Notes 6 and 7 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report for information relating to investments and fair value. These investments are sensitive to interest rate movements, and their fair value will decline as interest rates rise and increase as interest rates decline.&#160;The estimated impact on these investments of a 100 basis point (1.0%) increase in interest rates across the yield curve from rates in effect as of the balance sheet date would be a $1.7 million decline in value. </span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our earnings and cash flows from operations would be exposed to changes in interest rates because of the floating rate of interest&#160;in our 2025 Term Loan if such loan was not hedged using floating-to-fixed rate interest rate swaps. See Note 15 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report. The 2025 Term Loan bears interest at LIBOR plus a spread of 1.75%, subject to a minimum LIBOR rate of 0.00%. We have entered into interest rate swap arrangements (&#8220;interest rate swaps&#8221;) that fix the LIBOR rate of approximately $350.0 million of the 2025 Term Loan principal amount at 2.957% through September 2023. As such, a 100 basis point (1.0%) increase in the LIBOR rate as of our most recent LIBOR rate setting would increase our annualized interest expense by approximately $3.4 million on our 2025 Term Loan as&#160;recognized in our Consolidated Financial Statements.&#160;See Note 18 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report for information relating to our 2025 Term Loan. </span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Foreign Currency Exchange Risk. </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">As a global concern, our business and results of operations are exposed to and can be impacted by movements in foreign currency exchange rates. Because we sell globally, some of our sales transactions and revenue are non-U.S. Dollar denominated, with the Canadian Dollar, Euro and Japanese Yen being our most significant foreign currency revenue exposures. If the U.S. Dollar strengthens against these currencies, our revenue for these transactions reported in U.S. Dollars would decline. For our U.S. Dollar denominated sales, an increase in the value of the U.S. Dollar would increase the real costs of our products to customers in markets outside the United States, which could impact our competitive position. During fiscal 2020, approximately 15.9% of revenue was non-U.S. Dollar denominated. During fiscal 2020 as compared to fiscal 2019, the U.S. Dollar fluctuated against a number of foreign currencies. Consequently, our revenue reported in U.S. Dollars was slightly reduced by approximately $13.5 million or 0.4%. As it relates to costs of goods sold, employee-related and facilities costs associated with certain manufacturing-related operations in Canada represent our primary exposure to foreign currency exchange risk.</span></div><div style="margin-top:7.95pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">With regard to operating expense, our primary exposure to foreign currency exchange risk relates to the Canadian Dollar, Indian Rupee, Brazilian Real, British Pound and Euro. During fiscal 2020, approximately 48.5% of our operating expense was non-U.S. Dollar denominated. If currencies strengthen against the U.S. Dollar, costs reported in U.S. Dollars will increase.  During fiscal 2020 as compared to fiscal 2019, the U.S. Dollar fluctuated against these and other currencies. Consequently, our operating expense reported in U.S. Dollars was reduced by approximately $6.2 million, or 0.5%, net of hedging. </span></div><div style="margin-top:7.95pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">From time to time, we use foreign currency forward contracts to reduce variability in certain forecasted non-U.S. Dollar denominated cash flows. Generally, these derivatives have maturities of 24 months or less and are designated as cash flow hedges. At the inception of the cash flow hedge, and on an ongoing basis, we assess whether the forward contract has been effective in offsetting changes in cash flows attributable to the hedged risk during the hedging period. The derivative&#8217;s net gain or loss is initially reported as a component of accumulated other comprehensive income (loss) and, upon the occurrence of the forecasted transaction, is subsequently reclassified to the line item in the Consolidated Statement of Operations to which the hedged transaction relates. </span></div><div style="margin-top:7.95pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">During fiscal 2020, we recorded $13.0 million in foreign currency exchange losses, as a result of monetary assets and liabilities that were transacted in a currency other than the entity&#8217;s functional currency, and the re-measurement adjustments were recorded in interest and other income (loss), net on our Consolidated Statement of Operations. From time to time, we use foreign currency forwards to hedge these balance sheet exposures. These forwards are not designated as hedges for accounting purposes, and any net gain or loss associated with these derivatives is reported in interest and other income (loss), net. During fiscal 2020, we recorded a gain on non-hedge designated foreign currency forward contracts of $5.6 million.

Management establishes a reserve for excess and obsolete inventory when impairment has been identified and recorded a reserve for excess and obsolete inventory of $40 million as of October 31, 2020. Management writes down its inventory for estimated obsolescence or unmarketable inventory by an amount equal to the difference between the cost of inventory and the estimated net realizable value based on assumptions about future demand, which are affected by changes in the Company&#8217;s strategic direction, discontinuance of a product or introduction of newer versions of a product, declines in the sales of or forecasted demand for certain products, and general market conditions. </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">The principal considerations for our determination that performing procedures relating to the reserve for excess and obsolete inventory is a critical audit matter are the significant judgment by management when developing their estimate, which in turn led to a high degree of auditor judgment, subjectivity, and effort to perform procedures and evaluate the audit evidence obtained relating to the assumptions regarding future demand. </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements.

These procedures also included, among others, testing management&#8217;s process for determining the reserve for excess and obsolete inventory. This included evaluating the appropriateness of the inventory reserve method and the reasonableness of the significant assumptions relating to the future demand. Evaluating the assumptions related to future demand involved evaluating whether the assumptions used were reasonable considering historical sales and expectations regarding future sales. Testing management's process for determining future demand included procedures to evaluate the reliability, completeness and relevance of management's data used in the future demand assumption.

These purchase orders under framework agreements are used to determine the identification of the contract or contracts with this customer. Purchase orders typically include the description, quantity, and price of each product or service purchased. Purchase orders may include one-line bundled pricing for both products and services. Accordingly, purchase orders can include various combinations of products and services that are generally distinct and accounted for as separate performance obligations. Ciena evaluates each promised product and service offering to determine whether it represents a distinct performance obligation. In doing so, Ciena considers, among other things, customary business practices, whether the customer can benefit from the product or service on its own or together with other resources that are readily available, and whether Ciena&#8217;s commitment to transfer the product or service to the customer is separately identifiable from other obligations in the purchase order.

SSP is estimated for each distinct performance obligation, and judgment may be required in its determination. The best evidence of SSP is the observable price of a product or service when Ciena sells the products separately in similar circumstances and to similar customers.

In conjunction with this interpretation, Ciena considers each customer purchase in combination with the corresponding framework agreement, if applicable, as a contract. Ciena has elected to implement the practical expedient, which allows for incremental costs to be recognized as an expense when incurred if the period of the asset recognition is one year or less. If the period of the asset recognition is greater than one year, Ciena amortizes these costs over the period of performance. Ciena considers sales commissions incurred upon receipt of purchase orders placed by customers as incremental costs to obtain such purchase orders. The practical expedient method is applied to the purchase order as a whole and thus the capitalized costs of obtaining a purchase order is applied even if the purchase order contains more than one performance obligation. In cases where a purchase order includes various distinct products or services with both short-term (one year or less) and long-term (more than a year) performance periods, the cost of commissions incurred for the total value of the purchase order is capitalized and subsequently amortized as each performance obligation is recognized.</span></div></ix:continuation><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For the additional disclosures on capitalized contract acquisition costs, see Note 2 below.</span></div><div style="text-indent:18pt"><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Warranty Accruals</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"><ix:nonNumeric contextRef="i47b22543b9a64c3aa3ab2ae85daad67f_D20191103-20201031" name="us-gaap:StandardProductWarrantyPolicy" id="id3VybDovL2RvY3MudjEvZG9jOjJkOTU2NjYzYWY1ZDQ3Zjk5OThmMjJhODljZThhNzY2L3NlYzoyZDk1NjY2M2FmNWQ0N2Y5OTk4ZjIyYTg5Y2U4YTc2Nl84NS9mcmFnOjI2ZTBmZWE2MGMwNDQwNWNhNDFiOThlMjc4NDEwN2E4L3RleHRyZWdpb246MjZlMGZlYTYwYzA0NDA1Y2E0MWI5OGUyNzg0MTA3YThfNDY4Mjg_a7a387a1-a03e-48f2-b060-4f742f42d7ea" escape="true">Ciena provides for the estimated costs to fulfill customer warranty obligations upon recognition of the related revenue.

Ciena performs ongoing credit evaluations of its customers and generally has not required collateral or other forms of security from them. In determining the appropriate balance for Ciena&#8217;s allowance for doubtful accounts receivable, management considers each individual customer account receivable in order to determine collectibility. In doing so, management considers creditworthiness, payment history, account activity and communication with the customer. If a customer&#8217;s financial condition changes, or if actual defaults are higher than Ciena&#8217;s historical experience, Ciena may be required to take a charge for an allowance for doubtful accounts receivable, which could have an adverse impact on its results of operations.</ix:nonNumeric> </span></div><div style="text-indent:15.75pt"><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Research and Development</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"><ix:nonNumeric contextRef="i47b22543b9a64c3aa3ab2ae85daad67f_D20191103-20201031" name="us-gaap:ResearchDevelopmentAndComputerSoftwarePolicyTextBlock" id="id3VybDovL2RvY3MudjEvZG9jOjJkOTU2NjYzYWY1ZDQ3Zjk5OThmMjJhODljZThhNzY2L3NlYzoyZDk1NjY2M2FmNWQ0N2Y5OTk4ZjIyYTg5Y2U4YTc2Nl84NS9mcmFnOjI2ZTBmZWE2MGMwNDQwNWNhNDFiOThlMjc4NDEwN2E4L3RleHRyZWdpb246MjZlMGZlYTYwYzA0NDA1Y2E0MWI5OGUyNzg0MTA3YThfNDY5MjA_984e06d5-0242-4aee-909d-6524b59370e8" escape="true">Ciena charges all research and development costs to expense as incurred.

Ciena estimates the fair value of each option-based award on the date of grant using the Black-Scholes option-pricing model. This model is affected by Ciena&#8217;s stock price as well as estimates regarding a number of variables, including expected stock price volatility over the expected term of the award and projected employee stock option exercise behaviors. Ciena recognizes the estimated fair value of restricted stock units subject only to service-based vesting conditions by multiplying the number of shares underlying the award by the closing price per share of Ciena common stock on the grant date. In each case, Ciena only recognizes expense in its Consolidated Statement of Operations for those stock options or restricted stock units that are expected ultimately to vest. Awards with performance-based vesting conditions (i) require the achievement of certain operational, financial or other performance criteria or targets or (ii) vest based on Ciena&#8217;s total shareholder return as compared to an index of peer companies, in whole or in part. Ciena recognizes the estimated fair value of restricted stock units subject to performance-based vesting conditions other than total shareholder return by assuming the satisfaction of any performance-based objectives at the &#8220;target&#8221; level and multiplying the corresponding number of shares earned based upon such achievement by the closing price per share of Ciena common stock on the grant date. Ciena recognizes the estimated fair value of performance based awards subject to total shareholder return as compared to an index of peer companies using a Monte Carlo simulation valuation model on the date of grant. At the end of each reporting period, Ciena reassesses the probability of achieving the performance targets and the performance period required to meet those targets.</ix:nonNumeric> See Note 23 below.</span></div><div style="text-indent:15.75pt"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Stock Repurchase Plan</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"><ix:nonNumeric contextRef="i47b22543b9a64c3aa3ab2ae85daad67f_D20191103-20201031" name="us-gaap:StockholdersEquityPolicyTextBlock" id="id3VybDovL2RvY3MudjEvZG9jOjJkOTU2NjYzYWY1ZDQ3Zjk5OThmMjJhODljZThhNzY2L3NlYzoyZDk1NjY2M2FmNWQ0N2Y5OTk4ZjIyYTg5Y2U4YTc2Nl84NS9mcmFnOjI2ZTBmZWE2MGMwNDQwNWNhNDFiOThlMjc4NDEwN2E4L3RleHRyZWdpb246MjZlMGZlYTYwYzA0NDA1Y2E0MWI5OGUyNzg0MTA3YThfNDY4NTE_c2a1d0e8-a28e-4554-8385-455f4622a5f0" continuedAt="i6f775a796cba4f60bc3b54ecaea309e5" escape="true">Shares repurchased pursuant to Ciena&#8217;s share repurchase program are immediately retired upon purchase. Repurchased common stock is reflected as a reduction of stockholders&#8217; equity. Ciena&#8217;s accounting policy related to its share repurchases is to reduce its common stock based on the par value of the shares and to reduce its capital surplus for the excess of the repurchase price over the par value. Since the inception of its share repurchase program in December 2018, Ciena has had an accumulated deficit balance; therefore, the excess over the par value has been applied to additional paid-in capital. Once Ciena has retained earnings, the excess will be charged entirely to retained earnings.</ix:nonNumeric></span></div></ix:continuation><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">82</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i2d956663af5d47f9998f22a89ce8a766_7">Table of Contents</a></span></div></div><div style="text-indent:18pt"><span><br/></span></div><ix:continuation id="i18cb6e65f2e647a8b744ce3c3a20607e" continuedAt="i109b0b9699744612b0431654eeedbd3a"><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"><ix:continuation id="i6f775a796cba4f60bc3b54ecaea309e5">Due to the continued uncertainty surrounding the duration and severity of potential macroeconomic impacts of COVID-19, Ciena considered it prudent to temporarily suspend purchases of its common stock under its stock repurchase program effective as of March 17, 2020.

Accordingly, Ciena has not capitalized any software development costs.</ix:nonNumeric></span></div><div style="text-indent:18pt"><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Newly Issued Accounting Standards - Effective</span></div><div><span><br/></span></div><ix:nonNumeric contextRef="i47b22543b9a64c3aa3ab2ae85daad67f_D20191103-20201031" name="us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock" id="id3VybDovL2RvY3MudjEvZG9jOjJkOTU2NjYzYWY1ZDQ3Zjk5OThmMjJhODljZThhNzY2L3NlYzoyZDk1NjY2M2FmNWQ0N2Y5OTk4ZjIyYTg5Y2U4YTc2Nl84NS9mcmFnOjI2ZTBmZWE2MGMwNDQwNWNhNDFiOThlMjc4NDEwN2E4L3RleHRyZWdpb246MjZlMGZlYTYwYzA0NDA1Y2E0MWI5OGUyNzg0MTA3YThfNDY4ODc_73ef8a6f-d5ce-4d43-9f69-d0cfcbfa166a" continuedAt="i150240f97f124e959f6d8540b2bf46bd" escape="true"><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Leases</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In February 2016, FASB issued ASC 842</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">, Leases</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">, which requires an entity to recognize assets and liabilities on the balance sheet for the rights and obligations created by leased assets and to provide additional disclosures.

As a practical expedient, Ciena has elected not to capitalize leases with a term of 12 months or less without a purchase option that it is likely to exercise. Also as a practical expedient, Ciena has elected not to separate lease and non-lease components of operating and finance leases. Lease components are payment items directly attributable to the use of the underlying asset, while non-lease components are explicit elements of a contract not directly related to the use of the underlying asset, including pass-through operating expenses like common area maintenance and utilities. In connection with its adoption of ASC 842, Ciena has implemented new accounting policies and processes, and incorporated such into its existing internal control environment as necessary to support the requirements of ASC 842.</span></div><div style="text-align:justify;text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Upon adoption, Ciena recorded Operating ROU assets of $<ix:nonFraction unitRef="usd" contextRef="ia81f4e2b16a94c47956142691311810a_I20191103" decimals="-5" format="ixt:numdotdecimal" name="us-gaap:OperatingLeaseRightOfUseAsset" scale="6" id="id3VybDovL2RvY3MudjEvZG9jOjJkOTU2NjYzYWY1ZDQ3Zjk5OThmMjJhODljZThhNzY2L3NlYzoyZDk1NjY2M2FmNWQ0N2Y5OTk4ZjIyYTg5Y2U4YTc2Nl84NS9mcmFnOjI2ZTBmZWE2MGMwNDQwNWNhNDFiOThlMjc4NDEwN2E4L3RleHRyZWdpb246MjZlMGZlYTYwYzA0NDA1Y2E0MWI5OGUyNzg0MTA3YThfOTM0NTg0ODg5MTQ3Ng_a514d9ae-4df8-448a-af45-976ef32b572e">53.3</ix:nonFraction>&#160;million and lease liabilities of $<ix:nonFraction unitRef="usd" contextRef="ia81f4e2b16a94c47956142691311810a_I20191103" decimals="-5" format="ixt:numdotdecimal" name="us-gaap:OperatingLeaseLiability" scale="6" id="id3VybDovL2RvY3MudjEvZG9jOjJkOTU2NjYzYWY1ZDQ3Zjk5OThmMjJhODljZThhNzY2L3NlYzoyZDk1NjY2M2FmNWQ0N2Y5OTk4ZjIyYTg5Y2U4YTc2Nl84NS9mcmFnOjI2ZTBmZWE2MGMwNDQwNWNhNDFiOThlMjc4NDEwN2E4L3RleHRyZWdpb246MjZlMGZlYTYwYzA0NDA1Y2E0MWI5OGUyNzg0MTA3YThfOTM0NTg0ODg5MTUwNQ_a876cc02-d52d-4b31-9c8a-559cb09ec337">76.0</ix:nonFraction>&#160;million related to its operating leases.

Because our stockholders do not have cumulative voting rights, our stockholders holding a majority of the shares of common stock outstanding will be able to elect all of our directors. Our amended and restated certificate of incorporation provides for the removal of any of our directors, with or without cause, but only with a stockholder vote by the holders of at majority of the voting power of the then outstanding voting capital stock. Other than a vacancy resulting from such removal, which may be filled at a special meeting of stockholders, any vacancy on our board of directors, however occurring, may only be filled by a majority vote of the directors then in office, though less than a quorum. Furthermore, the authorized number of directors may be changed only by a resolution of our board of directors. This system of electing and removing directors, filling vacancies and fixing the size of our board may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of us, because it generally makes it more difficult for stockholders to replace a majority of the directors. </font></div><div style="text-indent:24pt"><font><br></font></div><div style="text-indent:24pt"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%">Amendment of Certificate of Incorporation and Bylaws.</font><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"> Our amended and restated certificate of incorporation provides that the approval of the holders of at least 66 2&#47;3% of the voting power of the then outstanding voting capital stock is necessary for the amendment or repeal of certain sections thereof.</font><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%"> </font><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">Our amended and restated certificate of incorporation also provides that any adoption, amendment or repeal of our amended and restated bylaws by our stockholders requires the approval the holders of at least 66 2&#47;3% of the voting power of the then outstanding voting capital stock.</font></div><div style="text-indent:24pt"><font><br></font></div><div style="text-indent:24pt"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%">Section 203 of the Delaware General Corporation Law.</font><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"> We are subject to Section 203 of the Delaware General Corporation Law, which, with specified exceptions, prohibits a Delaware corporation from engaging in any &#8220;business combination&#8221;

Foreign property, including Restricted Stock Units, shares of Stock acquired under the Plan and other rights to receive shares (e.g., Restricted Stock Units) of a non-Canadian company held by a Canadian resident must generally be reported annually on a Form T1135 (Foreign Income Verification Statement) if the total cost of the foreign property exceeds C$100,000 at any time during the year.  Thus, such Restricted Stock Units must be reported - generally at a nil cost - if the C$100,000 cost threshold is exceeded because other foreign property is held by you.  When shares of Stock are acquired, their cost generally is the adjusted cost base (&#8220;ACB&#8221;) of the shares.  The ACB would ordinarily equal the fair market value of the shares at the time of acquisition, but if you own other shares of the same company, this ACB may have to be averaged with the ACB of the other shares.  You should consult with your personal tax advisor to determine your reporting requirements.</font></div><div style="text-align:justify"><font><br></font></div><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:700;line-height:120%">COLOMBIA</font></div><div style="text-align:justify"><font><br></font></div><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%">Terms and Conditions</font></div><div style="text-align:justify"><font><br></font></div><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%">Acknowledgment of Nature of Grant</font><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">.

In addition, the sale of shares of Stock must also be declared on D-6 form filed with the DGCI in January, unless the sale proceeds exceed the applicable threshold (currently &#8364;1,502,530), in which case, the filing is due within one month after the sale. </font></div><div style="text-align:justify"><font><br></font></div><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">In addition, you may be required to electronically declare to the Bank of Spain any foreign accounts (including brokerage accounts held abroad), any foreign instruments (including shares of Stock acquired under the Plan), and any transactions with non-Spanish residents (including any payments of shares of Stock made pursuant to the Plan), depending on the balances in such accounts together with the value of such instruments as of December 31 of the relevant year, or the volume of transactions with non-Spanish residents during the relevant year.</font></div><div style="text-align:justify"><font><br></font></div><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%">Foreign Account &#47; Assets Reporting Information</font><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">.

Foreign property, including Restricted Stock Units, shares of Stock acquired under the Plan and other rights to receive shares (e.g., Restricted Stock Units) of a non-Canadian company held by a Canadian resident must generally be reported annually on a Form T1135 (Foreign Income Verification Statement) if the total cost of the foreign property exceeds C$100,000 at any time during the year.  Thus, such Restricted Stock Units must be reported - generally at a nil cost - if the C$100,000 cost threshold is exceeded because other foreign property is held by you.  When shares of Stock are acquired, their cost generally is the adjusted cost base (&#8220;ACB&#8221;) of the shares.  The ACB would ordinarily equal the fair market value of the shares at the time of acquisition, but if you own other shares of the same company, this ACB may have to be averaged with the ACB of the other shares.  You should consult with your personal tax advisor to determine your reporting requirements.</font></div><div style="margin-bottom:12pt;text-align:justify"><font><br></font></div><div style="text-align:justify"><font><br></font></div></td><td colspan="3" style="padding:0 1pt"></td></tr></table></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div><font><br></font></div></div></div><hr style="page-break-after:always"><div style="min-height:42.75pt;width:100%"><div><font><br></font></div></div><div style="margin-top:5pt;text-align:center"><table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:100.000%"><tr><td style="width:1.0%"></td><td style="width:31.759%"></td><td style="width:0.1%"></td><td style="width:1.0%"></td><td style="width:51.816%"></td><td style="width:0.1%"></td><td style="width:1.0%"></td><td style="width:13.125%"></td><td style="width:0.1%"></td></tr><tr><td colspan="3" style="padding:2px 1pt;text-align:left;vertical-align:top"><div><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:700;line-height:115%">United Kingdom Residents</font></div></td><td colspan="3" style="padding:2px 1pt;text-align:left;vertical-align:top"><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:115%">With respect to United Kingdom residents only&#58;</font></div><div style="text-align:justify"><font><br></font></div><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%">Taxes.</font><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"> This section supplements the Share Delivery Pursuant to Vested Restricted Stock Units&#59; Tax-Related Items section above&#58;</font></div><div><font><br></font></div><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">Without limitation to the provisions contained in the Share Delivery Pursuant to Vested Restricted Stock Units&#59; Tax-Related Items section of this Agreement, you agree that you are liable for all Tax-Related Items and hereby covenant to pay all such Tax-Related Items as and when requested by the Company or the Employer or by Her Majesty&#8217;s Revenue and Customs (&#8220;HMRC&#8221;) (or any other tax authority or any other relevant authority).</font><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:12pt;font-weight:400;line-height:120%">  </font><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">You also agree to indemnify and keep indemnified the Company and the Employer against any Tax-Related Items that they are required to pay or withhold on your behalf or have paid or will pay to HMRC (or any other tax authority or any other relevant authority).</font></div><div><font><br></font></div><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%">Joint Election. </font><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">As a condition of your participation in the Plan and of the vesting of the Restricted Stock Units, you agree to accept any liability for secondary Class 1 National Insurance Contributions which may be payable by the Company and&#47;or the Employer with respect to the vesting of the Restricted Stock Units or otherwise payable in connection with the shares of Stock and the right to acquire shares of Stock (&#8220;Employer NICs&#8221;).</font></div><div><font><br></font></div><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">Without limitation to the foregoing, you agree to execute a joint election with the Company or the Employer, the form of such joint election being formally approved by HMRC (the &#8220;Joint Election&#8221;), and any other required consents or elections as provided to you by the Company or the Employer.

Thus, such Restricted Stock Units must be reported - generally at a nil cost - if the C$100,000 cost threshold is exceeded because other foreign property is held by you.  When shares of Stock are acquired, their cost generally is the adjusted cost base (&#8220;ACB&#8221;) of the shares.  The ACB would ordinarily equal the fair market value of the shares at the time of acquisition, but if you own other shares of the same company, this ACB may have to be averaged with the ACB of the other shares.  You should consult with your personal tax advisor to determine your reporting requirements.</font></div></td></tr><tr><td colspan="3" style="padding:2px 1pt;text-align:left;vertical-align:top"><div><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:700;line-height:115%">United Kingdom Residents</font></div></td><td colspan="3" style="padding:2px 1pt;text-align:left;vertical-align:top"><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">With respect to United Kingdom residents only&#58;</font></div><div style="text-align:justify"><font><br></font></div><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%">Taxes.</font><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"> This section supplements the Share Delivery Pursuant to Vested Restricted Stock Units&#59; Tax-Related Items section above&#58;</font></div><div style="text-align:justify"><font><br></font></div><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">Without limitation to the provisions contained in the Share Delivery Pursuant to Vested Restricted Stock Units&#59; Tax-Related Items section of this Agreement, you agree that you are liable for all Tax-Related Items and hereby covenant to pay all such Tax-Related Items as and when requested by the Company or the Employer or by Her Majesty&#8217;s Revenue and Customs (&#8220;HMRC&#8221;) (or any other tax authority or any other relevant authority).

Fiscal 2020 and fiscal 2019 each consisted of a 52-week fiscal year and fiscal 2018 consisted of a 53-week fiscal year. Effective the second quarter of fiscal 2020, Ciena changed the presentation of reporting for its financial statements and notes thereto to reflect the actual dates on which fiscal years ended. Because these dates can change from period to period, for consistency purposes, Ciena previously presented such information indicating that its fiscal years ended on October&#160;31. This change, affecting only the presentation of such information, was made on a prospective basis and it does not impact comparability of previous financial results. Reference to prior reported periods have been changed to reflect the actual period end dates of November&#160;2, 2019, November&#160;3, 2018 and October&#160;28, 2017 for periods reported herein.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Business Combinations&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena records acquisitions using the purchase method of accounting. All of the assets acquired, liabilities assumed, contractual contingencies and contingent consideration are recognized at their fair value as of the acquisition date. The excess of the purchase price over the estimated fair values of the net tangible and net intangible assets acquired is recorded as goodwill. The application of the purchase method of accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed, in order to properly allocate purchase price consideration between assets that are depreciated and amortized from goodwill. These assumptions and estimates include a market participant&#x2019;s use of the asset and the appropriate discount rates for a market &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;participant. Ciena&#x2019;s estimates are based on historical experience, information obtained from the management of the acquired companies and, when appropriate, include assistance from independent third-party appraisal firms. Significant assumptions and estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted-average cost of capital and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable. In addition, unanticipated events and circumstances may occur which may affect the accuracy or validity of such estimates.&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Use of Estimates&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The preparation of the financial statements and related disclosures in conformity with Generally Accepted Accounting Principles (&#x201c;GAAP&#x201d;)&#160;requires management to make estimates and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. Estimates are used for selling prices for multiple element arrangements, shared-based compensation, bad debts, valuation of inventories and investments, recoverability of intangible assets, other long-lived assets and goodwill, income taxes, warranty obligations, restructuring liabilities, derivatives, contingencies and litigation. Ciena bases its estimates on historical experience and assumptions that it believes are reasonable. Actual results may differ materially from management&#x2019;s estimates.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Cash and Cash Equivalents&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Any restricted cash collateralizing letters of credit is included in other current assets and other long-term assets depending on the duration of the restriction.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:15.75pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Investments&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena&#x2019;s investments in debt securities are classified as available-for-sale and reported at fair value, with unrealized gains and losses recorded in accumulated other comprehensive income (loss). Ciena recognizes losses in the income statement when it determines that declines in the fair value of its investments below their cost basis are other-than-temporary. In determining whether a decline in fair value is other-than-temporary, Ciena considers various factors, including market price (when available), investment ratings, the financial condition and near-term prospects of the investee, the length of time and the extent to which the fair value has been less than Ciena&#x2019;s cost basis, and Ciena&#x2019;s intent and ability to hold the investment until maturity or for a period of time sufficient to allow for any anticipated recovery in market value. Ciena considers all marketable debt securities that it expects to convert to cash within one year or less to be short-term investments, with all others considered to be long-term investments.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena has minority equity investments in privately held technology companies that are classified in other long-term assets. These investments are carried at cost because Ciena owns less than 20% of the voting equity and does not have the ability to exercise significant influence over the company. Ciena monitors these investments for impairment and makes appropriate reductions to the carrying value when necessary. As of&#160;October&#160;31, 2020, the combined carrying value of these investments was&#160;$13.4 million. Ciena elects to estimate the fair value at cost minus impairment, if any, plus or minus observable price changes in orderly transactions for identical or similar investments of the same issuer. Ciena evaluates these investments for impairment or observable price changes quarterly and records adjustments to interest and other income (loss), net on the Consolidated Statements of Operations. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Inventories&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Inventories are stated at the lower of cost or market, with cost computed using standard cost, which approximates actual cost, on a first-in, first-out basis. Ciena records a provision for excess and obsolete inventory when an impairment has been identified.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Segment Reporting&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena&#x2019;s chief operating decision maker, its chief executive officer, evaluates the Company&#x2019;s performance and allocates resources based on multiple factors, including measures of segment profit (loss). Operating segments are defined as components of an enterprise that engage in business activities that may earn revenue and incur expense, for which discrete financial information is available, and for which such information is evaluated regularly by the chief operating decision maker for purposes of allocating resources and assessing performance. Ciena has the following operating segments for reporting purposes: (i) Networking Platforms; (ii) Platform Software and Services; (iii) Blue Planet Automation Software and Services; and (iv) Global Services. See Note 24 below.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Goodwill&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&#160;&#160;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Goodwill is the excess of the purchase price over the fair values assigned to the net assets acquired in a business combination. Ciena tests goodwill for impairment on an annual basis, which it has determined to be the last business day of fiscal September each year. Ciena also tests goodwill for impairment between annual tests if an event occurs or circumstances change that would, more likely than not, reduce the fair value of the reporting unit below its carrying value. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena tests goodwill impairment by comparing the fair value of the reporting unit with the unit&#x2019;s carrying amount, including goodwill. If this test indicates that the fair value is less than the carrying value, then an impairment loss is recognized limited to the total amount of goodwill allocated to that reporting unit. A non-cash goodwill impairment charge would have the effect of decreasing earnings or increasing losses in such period. If Ciena is required to take a substantial impairment charge, its operating results would be materially adversely affected in such period.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Long-lived Assets&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Long-lived assets include: equipment, building, furniture and fixtures, ROU assets, finite-lived intangible assets and maintenance spares. Ciena tests long-lived assets for impairment whenever triggering events or changes in circumstances indicate that the asset&#x2019;s carrying amount is not recoverable from its undiscounted cash flows. An impairment loss is measured as the amount by which the carrying amount of the asset or asset group exceeds its fair value. Ciena&#x2019;s long-lived assets are assigned to asset groups that represent the lowest level for which cash flows can be identified.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Equipment, Building, Furniture and Fixtures and Internal Use Software&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Equipment, building, furniture and fixtures are recorded at cost. Depreciation and amortization are computed using the straight-line method over useful lives of&#160;two years&#160;to&#160;five years for equipment and furniture and fixtures and the shorter of useful life or lease term for leasehold improvements.&#160;&#160;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&#160;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Qualifying internal use software and website development costs incurred during the application development stage, which consist primarily of outside services and purchased software license costs, are capitalized and amortized straight-line over the estimated useful lives of&#160;two years&#160;to&#160;five years.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Leases&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;At the inception of a contract, Ciena must determine whether the contract is or contains a lease. The contract is or contains a lease if the contract conveys the right to control the use of the property, plant, or equipment for a designated term in exchange for consideration. Ciena&#x2019;s evaluation of its contracts follows the assessment of whether there is a right to obtain substantially all of the economic benefits from the use and the right to direct the use of the identified asset in the contract. Operating leases are included in the Operating right-of-use assets (&#x201c;Operating ROU assets&#x201d;), Operating lease liabilities and Long-term operating lease liabilities in the Consolidated Balance Sheets. Finance leases are included in Equipment, building, furniture and fixtures, net (&#x201c;Finance ROU assets&#x201d;), Accrued liabilities and other short-term obligations and Other long-term obligations in the Consolidated Balance Sheets.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena has operating and finance leases that primarily relate to real property. Ciena has elected not to capitalize leases with a term of 12 months or less without a purchase option that it is likely to exercise. Ciena has elected not to separate lease and non-lease components of operating and finance leases. Lease components are payment items directly attributable to the use of the underlying asset, while non-lease components are explicit elements of a contract not directly related to the use of the underlying asset, including pass-through operating expenses like common area maintenance and utilities.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Operating ROU assets and lease liabilities and Finance ROU assets and lease liabilities are recognized on the Consolidated Balance Sheets at the present value of the future lease payments over the life of the lease term. Ciena uses discount rates based on incremental borrowing rates, on a collateralized basis, for the respective underlying assets, for terms similar to the respective leases when implicit rates for leases are not determinable. Operating lease costs are included as rent expense in the Consolidated Statements of Operations. Fixed base payments on operating leases paid directly to the lessor are recorded as lease expense on a straight-line basis. Related variable payments based on usage, changes in an index, or market rate are expensed as incurred. Finance ROU assets are generally amortized on a straight-line basis over the lease term with the interest expense on the lease liability recorded using the interest method. The amortization and interest expense are recorded separately in the Consolidated Statements of Operations. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Intangible Assets&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena has recorded finite-lived intangible assets as a result of several acquisitions. Finite-lived intangible assets are carried at cost less accumulated amortization. Amortization is computed using the straight-line method over the expected economic lives of the respective assets, up to seven years, which approximates the use of intangible assets. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Maintenance Spares&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Maintenance spares are recorded at cost. Spares usage cost is expensed ratably over four years. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Concentrations&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Substantially all of Ciena&#x2019;s cash and cash equivalents are maintained at a small number of major U.S. financial institutions. The majority of Ciena&#x2019;s cash equivalents consist of money market funds. Deposits held with banks may exceed the amount of insurance provided on such deposits. Because these deposits generally may be redeemed upon demand, management believes that they bear minimal risk.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Historically, a significant percentage of Ciena&#x2019;s revenue has been concentrated among sales to a small number of large communications service providers and Web-scale providers. Consolidation among Ciena&#x2019;s customers has increased this concentration. Consequently, Ciena&#x2019;s accounts receivable are concentrated among these customers. See Note 24 below. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Additionally, Ciena&#x2019;s access to certain materials or components is dependent on sole or limited source suppliers. The inability of any of these suppliers to fulfill Ciena&#x2019;s supply requirements, or significant changes in supply cost, could affect future results. Ciena relies on a small number of contract manufacturers to perform the majority of the manufacturing for its products. If Ciena cannot effectively manage these manufacturers or forecast future demand, or if these manufacturers fail to deliver products or components on time, Ciena&#x2019;s business and results of operations may suffer.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Revenue Recognition&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena recognizes revenue when control of the promised products or services is transferred to its customer, in an amount that reflects the consideration to which Ciena expects to be entitled in exchange for those products or services.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena determines revenue recognition by applying the following five-step approach:&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:32.5pt"&gt;identification of the contract, or contracts, with a customer;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:32.5pt"&gt;identification of the performance obligations in the contract;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:32.5pt"&gt;determination of the transaction price;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:32.5pt"&gt;allocation of the transaction price to the performance obligations in the contract; and&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:32.5pt"&gt;recognition of revenue when, or as, Ciena satisfies a performance obligation.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Generally, Ciena makes sales pursuant to purchase orders placed by customers under framework agreements that govern the general commercial terms and conditions of the sale of Ciena&#x2019;s products and services. These purchase orders under framework agreements are used to determine the identification of the contract or contracts with this customer. Purchase orders typically include the description, quantity, and price of each product or service purchased. Purchase orders may include one-line bundled pricing for both products and services. Accordingly, purchase orders can include various combinations of products and services that are generally distinct and accounted for as separate performance obligations. Ciena evaluates each promised product and service offering to determine whether it represents a distinct performance obligation. In doing so, Ciena considers, among other things, customary business practices, whether the customer can benefit from the product or service on its own or together with other resources that are readily available, and whether Ciena&#x2019;s commitment to transfer the product or service to the customer is separately identifiable from other obligations in the purchase order. For transactions where Ciena delivers the product or services, Ciena is typically the principal and records revenue and costs of goods sold on a gross basis.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:3pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Purchase orders are invoiced based on the terms set forth either in the purchase order or the framework agreement, as applicable. Generally, sales of products and software licenses are invoiced upon shipment or delivery. Maintenance and software subscription services are invoiced quarterly or annually in advance of the service term. Ciena&#x2019;s other service offerings are generally invoiced upon completion of the service. Payment terms and cash received typically range from 30 to 90 days from the invoicing date. Historically, Ciena has not provided any material financing arrangements to its customers. As a practical expedient, Ciena does not adjust the amount of consideration it will receive for the effects of a significant financing &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:3pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;component as it expects, at contract inception, that the period between Ciena transfer of the products or services to the customer, and customer payment for the products or services will be one year or less. Shipping and handling fees invoiced to customers are included in revenue, with the associated expense included in product cost of goods sold. Ciena records revenue net of any associated sales taxes.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena recognizes revenue upon the transfer of control of promised products or services to a customer. Transfer of control occurs once the customer has the contractual right to use the product, generally upon shipment or delivery to the customer. Transfer of control can also occur over time for services such as software subscription, maintenance, installation, and various professional services as the customer receives the benefit over the contract term. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Significant Judgments &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Revenue is allocated among performance obligations based on standalone selling price (&#x201c;SSP&#x201d;). SSP reflects the price at which Ciena would expect to sell that product or service on a stand-alone basis at contract inception and that Ciena would expect to be entitled to receive for the promised products or services. SSP is estimated for each distinct performance obligation, and judgment may be required in its determination. The best evidence of SSP is the observable price of a product or service when Ciena sells the products separately in similar circumstances and to similar customers. In instances where SSP is not directly observable, Ciena determines SSP using information that may include market conditions and other observable inputs. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena applies judgment in determining the transaction price, as Ciena may be required to estimate variable consideration when determining the amount of revenue to recognize. Variable consideration can include various rebate, cooperative marketing, and other incentive programs that Ciena offers to its distributors, partners and customers. When determining the amount of revenue to recognize, Ciena estimates the expected usage of these programs, applying the expected value or most likely estimate and updates the estimate at each reporting period as actual utilization data becomes available. Ciena also considers any customer right of return and any actual or potential payment of liquidated damages, contractual or similar penalties, or other claims for performance failures or delays in determining the transaction price, where applicable.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;When transfer of control is judged to be over time for installation and professional service arrangements, Ciena applies the input method to determine the amount of revenue to be recognized in a given period. Utilizing the input method, Ciena recognizes revenue based on the ratio of actual costs incurred to date to the total estimated costs expected to be incurred. Revenue for software subscription and maintenance is recognized ratably over the period during which the services are performed. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Capitalized Contract Acquisition Costs&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena has considered the impact of the guidance in ASC 340-40, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Other Assets and Deferred Costs; Contracts with Customers&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;, and the interpretations of the Financial Accounting Standards Board (&#x201c;FASB&#x201d;) Transition Resource Group for Revenue Recognition with respect to capitalization and amortization of incremental costs of obtaining a contract. In conjunction with this interpretation, Ciena considers each customer purchase in combination with the corresponding framework agreement, if applicable, as a contract. Ciena has elected to implement the practical expedient, which allows for incremental costs to be recognized as an expense when incurred if the period of the asset recognition is one year or less. If the period of the asset recognition is greater than one year, Ciena amortizes these costs over the period of performance. Ciena considers sales commissions incurred upon receipt of purchase orders placed by customers as incremental costs to obtain such purchase orders. The practical expedient method is applied to the purchase order as a whole and thus the capitalized costs of obtaining a purchase order is applied even if the purchase order contains more than one performance obligation. In cases where a purchase order includes various distinct products or services with both short-term (one year or less) and long-term (more than a year) performance periods, the cost of commissions incurred for the total value of the purchase order is capitalized and subsequently amortized as each performance obligation is recognized.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;For the additional disclosures on capitalized contract acquisition costs, see Note 2 below.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Warranty Accruals&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena provides for the estimated costs to fulfill customer warranty obligations upon recognition of the related revenue. Estimated warranty costs include estimates for material costs, technical support labor costs and associated overhead. Warranty is included in cost of goods sold and is determined based on actual warranty cost experience, estimates of component failure rates and management&#x2019;s industry experience. Ciena&#x2019;s sales contracts do not permit the right of return of the product by the customer after the product has been accepted.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Accounts Receivable, Net&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena&#x2019;s allowance for doubtful accounts receivable is based on its assessment, on a specific identification basis, of the collectibility of customer accounts. Ciena performs ongoing credit evaluations of its customers and generally has not required collateral or other forms of security from them. In determining the appropriate balance for Ciena&#x2019;s allowance for doubtful accounts receivable, management considers each individual customer account receivable in order to determine collectibility. In doing so, management considers creditworthiness, payment history, account activity and communication with the customer. If a customer&#x2019;s financial condition changes, or if actual defaults are higher than Ciena&#x2019;s historical experience, Ciena may be required to take a charge for an allowance for doubtful accounts receivable, which could have an adverse impact on its results of operations. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:15.75pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Research and Development&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena charges all research and development costs to expense as incurred. Types of expense incurred in research and development include employee compensation, prototype equipment, consulting and third-party services, depreciation, facility costs and information technology.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Government Grants&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena accounts for proceeds from government grants as a reduction of expense when there is reasonable assurance that Ciena has met the required conditions associated with the grant and that grant proceeds will be received. Grant benefits are recorded to the particular line item of the Consolidated Statement of Operations to which the grant activity relates. See Note&#160;26&#160;below.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Advertising Costs&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena expenses all advertising costs as incurred.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Legal Costs&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena expenses legal costs associated with litigation as incurred.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:15.75pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Share-Based Compensation Expense&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena measures and recognizes compensation expense for share-based awards based on estimated fair values on the date of grant. Ciena estimates the fair value of each option-based award on the date of grant using the Black-Scholes option-pricing model. This model is affected by Ciena&#x2019;s stock price as well as estimates regarding a number of variables, including expected stock price volatility over the expected term of the award and projected employee stock option exercise behaviors. Ciena recognizes the estimated fair value of restricted stock units subject only to service-based vesting conditions by multiplying the number of shares underlying the award by the closing price per share of Ciena common stock on the grant date. In each case, Ciena only recognizes expense in its Consolidated Statement of Operations for those stock options or restricted stock units that are expected ultimately to vest. Awards with performance-based vesting conditions (i) require the achievement of certain operational, financial or other performance criteria or targets or (ii) vest based on Ciena&#x2019;s total shareholder return as compared to an index of peer companies, in whole or in part. Ciena recognizes the estimated fair value of restricted stock units subject to performance-based vesting conditions other than total shareholder return by assuming the satisfaction of any performance-based objectives at the &#x201c;target&#x201d; level and multiplying the corresponding number of shares earned based upon such achievement by the closing price per share of Ciena common stock on the grant date. Ciena recognizes the estimated fair value of performance based awards subject to total shareholder return as compared to an index of peer companies using a Monte Carlo simulation valuation model on the date of grant. At the end of each reporting period, Ciena reassesses the probability of achieving the performance targets and the performance period required to meet those targets. See Note 23 below.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:15.75pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Stock Repurchase Plan&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Shares repurchased pursuant to Ciena&#x2019;s share repurchase program are immediately retired upon purchase. Repurchased common stock is reflected as a reduction of stockholders&#x2019; equity. Ciena&#x2019;s accounting policy related to its share repurchases is to reduce its common stock based on the par value of the shares and to reduce its capital surplus for the excess of the repurchase price over the par value. Since the inception of its share repurchase program in December 2018, Ciena has had an accumulated deficit balance; therefore, the excess over the par value has been applied to additional paid-in capital. Once Ciena has retained earnings, the excess will be charged entirely to retained earnings.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Due to the continued uncertainty surrounding the duration and severity of potential macroeconomic impacts of COVID-19, Ciena considered it prudent to temporarily suspend purchases of its common stock under its stock repurchase program effective as of March 17, 2020. See Note 27 below for information related to the resumption of purchases under this plan in fiscal 2021. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Income Taxes&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena accounts for income taxes using an asset and liability approach. This approach recognizes deferred tax assets and liabilities (&#x201c;DTA&#x201d;) for the expected future tax consequences attributable to differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax bases, and for operating loss and tax credit carryforwards. In estimating future tax consequences, Ciena considers all expected future events other than the enactment of changes in tax laws or rates. Valuation allowances are provided if, based on the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In the ordinary course of business, transactions occur for which the ultimate outcome may be uncertain. In addition, tax authorities periodically audit Ciena&#x2019;s income tax returns. These audits examine significant tax filing positions, including the timing and amounts of deductions and the allocation of income tax expenses among tax jurisdictions. Ciena is currently under audit in India for 2012 and 2014 through 2018, in Canada for 2013 through 2015, and in the United Kingdom for 2014 through 2018. Management does not expect the outcome of these audits to have a material adverse effect on Ciena&#x2019;s consolidated financial position, results of operations or cash flows. Ciena&#x2019;s major tax jurisdictions and the earliest open tax years are as follows: United States (2017), United Kingdom (2014), Canada (2013), and India (2012). Limited adjustments can be made to federal U.S. tax returns in earlier years in order to reduce net operating loss carryforwards. Ciena classifies interest and penalties related to uncertain tax positions as a component of income tax expense.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena has not provided for U.S. deferred income taxes on the cumulative unremitted earnings of its non-U.S. affiliates, as it plans to indefinitely reinvest these foreign earnings outside the U.S. As of October&#160;31, 2020, the cumulative amount of such temporary differences for which a deferred tax liability has not been recognized totaled approximately $375.0 million. If these earnings were distributed to the U.S. in the form of dividends, or otherwise, or if the shares of the relevant foreign subsidiaries were sold or otherwise transferred, Ciena would be subject to additional U.S. income taxes (subject to an adjustment for foreign tax credits) and foreign withholding taxes.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena is required to record excess tax benefits or tax deficiencies related to stock-based compensation as income tax benefit or expense when share-based awards vest or are settled. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena adopted ASU 2016-09, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Improvements to Employee Share-Based Payment Accounting, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;in the first quarter of fiscal 2018. In connection with the adoption of this guidance, Ciena recognized approximately $62.1 million of deferred tax assets related to previously unrecognized tax benefits. This was recorded as a cumulative-effect adjustment to retained earnings as of the beginning of the first quarter of fiscal 2018.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Tax Cuts and Jobs Act (the &#x201c;Tax Act&#x201d;) includes provisions that affected Ciena in fiscal 2019 and fiscal 2020, including a provision designed to tax global intangible low-taxed income (&#x201c;GILTI&#x201d;). An accounting policy choice is allowed to either treat taxes due on future U.S. inclusions related to GILTI in taxable income as a current-period expense when incurred (the &#x201c;period cost method&#x201d;) or factor such amounts into the measurement of deferred taxes (the &#x201c;deferred method&#x201d;). The calculation of the deferred balance with respect to the GILTI tax provisions will depend, in part, on analyzing global income to determine whether future U.S. inclusions in taxable income are expected related to GILTI and, if so, what the impact is expected to be. Ciena is electing to use the period cost method for future GILTI inclusions. Additionally, Ciena is electing to use the incremental cash tax savings approach when determining whether a valuation allowance needs to be recorded against the U.S. net operating loss (&#x201c;NOL&#x201d;) due to the GILTI inclusions.&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Tax Act also introduced an alternative tax known as the base erosion and anti-abuse tax (&#x201c;BEAT&#x201d;).&#160;An accounting policy choice has been made to consider BEAT as a period cost when incurred.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Loss Contingencies&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena 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. Ciena considers the likelihood of loss or the incurrence of a liability, as well as Ciena&#x2019;s ability to estimate the amount of loss reasonably, in determining loss contingencies. 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. Ciena regularly evaluates &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;current information available to it in order to determine whether any accruals should be adjusted and whether new accruals are required.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Fair Value of Financial Instruments&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The carrying value of Ciena&#x2019;s cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximates fair market value due to the relatively short period of time to maturity. For information related to the fair value of Ciena&#x2019;s term loan, see Note 18 below.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Fair value for the measurement of financial assets and liabilities is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. Ciena utilizes a valuation hierarchy for disclosure of the inputs for fair value measurement. This hierarchy prioritizes the inputs into three broad levels as follows: &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities; &lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;Level 2 inputs are quoted prices for identical or similar assets or liabilities in less active markets or model-derived valuations in which significant inputs are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; and&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;Level 3 inputs are unobservable inputs based on Ciena&#x2019;s assumptions used to measure assets and liabilities at fair value. The fair values are determined based on model-based techniques using inputs Ciena could not corroborated with market data.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;By distinguishing between inputs that are observable in the marketplace, and therefore more objective, and those that are unobservable, and therefore more subjective, the hierarchy is designed to indicate the relative reliability of the fair value measurements. A financial asset&#x2019;s or liability&#x2019;s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Restructuring&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;From time to time, Ciena takes actions to better align its workforce, facilities and operating costs with perceived market opportunities, business strategies and changes in market and business conditions and redesign business processes. Ciena recognizes a liability for the cost associated with an exit or disposal activity in the period in which the liability is incurred, except for one-time employee termination benefits related to a service period, typically of more than 60 days, which are accrued over the service period. See Note 4 below.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Foreign Currency&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Certain of Ciena&#x2019;s foreign branch offices and subsidiaries use the U.S. Dollar as their functional currency because Ciena Corporation, as the U.S. parent entity, exclusively funds the operations of these branch offices and subsidiaries. For those subsidiaries using the local currency as their functional currency, assets and liabilities are translated at exchange rates in effect at the balance sheet date, and the statement of operations is translated at a monthly average rate. Resulting translation adjustments are recorded directly to a separate component of stockholders&#x2019; equity. Where the monetary assets and liabilities are transacted in a currency other than the entity&#x2019;s functional currency, re-measurement adjustments are recorded in interest and other income (loss), net on the Consolidated Statement of Operations. See Note 5 below.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Derivatives&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena&#x2019;s&#160;3.75%&#160;Convertible Senior Notes due October 15, 2018 (the &#x201c;New Notes&#x201d;) included a conversion feature that was accounted for as a separate embedded derivative. The embedded conversion feature was recorded at fair value using the underlying stock price, time to maturity and expected volatility of Ciena&#x2019;s stock and conversion price. These changes are included in interest and other income (loss), net on the Consolidated Statement of Operations. On November 15, 2018, Ciena settled this embedded conversion feature. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;From time to time, Ciena uses foreign currency forward contracts to reduce variability in certain forecasted non-U.S. Dollar denominated cash flows. Generally, these derivatives have maturities of 24 months or less. Ciena also has interest rate swap arrangements to reduce variability in certain forecasted interest expense associated with its term loan. All of these derivatives &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;are designated as cash flow hedges. At the inception of the cash flow hedge, and on an ongoing basis, Ciena assesses whether the derivative has been effective in offsetting changes in cash flows attributable to the hedged risk during the hedging period. The derivative&#x2019;s net gain or loss is initially reported as a component of accumulated other comprehensive income (loss), and, upon occurrence of the forecasted transaction, is subsequently reclassified to the line item in the Consolidated Statement of Operations to which the hedged transaction relates. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena records derivative instruments in the Consolidated Statements of Cash Flows within operating, investing, or financing activities consistent with the cash flows of the hedged items.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;From time to time, Ciena uses foreign currency forward contracts to hedge certain balance sheet foreign exchange exposures. These forward contracts are not designated as hedges for accounting purposes, and any net gain or loss associated with these derivatives is reported in interest and other income (loss), net on the Consolidated Statement of Operations. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;See Notes 7 and 15 below.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Computation of Net Income (Loss) per Share &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena calculates basic earnings per share by dividing earnings attributable to common stock by the weighted average number of common shares outstanding for the period. Diluted net income (loss) per potential common share (&#x201c;Diluted EPS&#x201d;) includes other potential dilutive shares that would be outstanding if securities or other contracts to issue common stock were exercised or converted into common stock. Ciena uses a dual presentation of basic net income (loss) per common share (&#x201c;Basic EPS&#x201d;) and Diluted EPS on the face of its income statement. A reconciliation of the numerator and denominator used for the Basic EPS and Diluted EPS computations is set forth in Note 20 below.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Software Development Costs&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena develops software for sale to its customers. GAAP requires the capitalization of certain software development costs that are incurred subsequent to the date technological feasibility is established and prior to the date the product is generally available for sale. The capitalized cost is then amortized using the straight-line method over the estimated life of the product. Ciena defines technological feasibility as being attained at the time a working model is completed. To date, the period between Ciena achieving technological feasibility and the general availability of such software has been short, and software development costs qualifying for capitalization have been insignificant. Accordingly, Ciena has not capitalized any software development costs.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Newly Issued Accounting Standards - Effective&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Leases&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In February 2016, FASB issued ASC 842&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;, Leases&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;, which requires an entity to recognize assets and liabilities on the balance sheet for the rights and obligations created by leased assets and to provide additional disclosures. Effective November 3, 2019, Ciena adopted ASC 842, which requires right-of-use ("ROU") assets and lease liabilities to be recorded on the balance sheet, on a modified retrospective basis, such that related amounts in prior periods have not been restated.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;As a practical expedient for disclosure, Ciena has elected the &#x201c;package of practical expedients&#x201d; and, as a result, did not reassess existing lease identifications, lease classifications or initial direct costs. As a practical expedient, Ciena has elected not to capitalize leases with a term of 12 months or less without a purchase option that it is likely to exercise. Also as a practical expedient, Ciena has elected not to separate lease and non-lease components of operating and finance leases. Lease components are payment items directly attributable to the use of the underlying asset, while non-lease components are explicit elements of a contract not directly related to the use of the underlying asset, including pass-through operating expenses like common area maintenance and utilities. In connection with its adoption of ASC 842, Ciena has implemented new accounting policies and processes, and incorporated such into its existing internal control environment as necessary to support the requirements of ASC 842.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Upon adoption, Ciena recorded Operating ROU assets of $53.3&#160;million and lease liabilities of $76.0&#160;million related to its operating leases. As of November&#160;2, 2019, the restructuring reserve liability for vacated office space of $11.1&#160;million was included in Accrued liabilities and other short-term obligations and Other long-term obligations on the Consolidated Balance Sheet under prior accounting guidance. Upon adoption of ASC 842, the existing lease reserve liability was reclassified as a reduction to the Operating ROU assets. ROU assets will be tested for impairment when circumstances indicate that the carrying &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;values may not be recoverable. The adoption of this guidance did not require a cumulative effect adjustment or have an impact on the Consolidated Statements of Operations or Consolidated Statements of Cash Flows.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times

Because these dates can change from period to period, for consistency purposes, Ciena previously presented such information indicating that its fiscal years ended on October&#160;31.

All of the assets acquired, liabilities assumed, contractual contingencies and contingent consideration are recognized at their fair value as of the acquisition date. The excess of the purchase price over the estimated fair values of the net tangible and net intangible assets acquired is recorded as goodwill. The application of the purchase method of accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed, in order to properly allocate purchase price consideration between assets that are depreciated and amortized from goodwill. These assumptions and estimates include a market participant&#x2019;s use of the asset and the appropriate discount rates for a market participant. Ciena&#x2019;s estimates are based on historical experience, information obtained from the management of the acquired companies and, when appropriate, include assistance from independent third-party appraisal firms. Significant assumptions and estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted-average cost of capital and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable. In addition, unanticipated events and circumstances may occur which may affect the accuracy or validity of such estimates.</us-gaap:BusinessCombinationsPolicy>

Ciena recognizes losses in the income statement when it determines that declines in the fair value of its investments below their cost basis are other-than-temporary. In determining whether a decline in fair value is other-than-temporary, Ciena considers various factors, including market price (when available), investment ratings, the financial condition and near-term prospects of the investee, the length of time and the extent to which the fair value has been less than Ciena&#x2019;s cost basis, and Ciena&#x2019;s intent and ability to hold the investment until maturity or for a period of time sufficient to allow for any anticipated recovery in market value. Ciena considers all marketable debt securities that it expects to convert to cash within one year or less to be short-term investments, with all others considered to be long-term investments.Ciena has minority equity investments in privately held technology companies that are classified in other long-term assets. These investments are carried at cost because Ciena owns less than 20% of the voting equity and does not have the ability to exercise significant influence over the company. Ciena monitors these investments for impairment and makes appropriate reductions to the carrying value when necessary. As of&#160;October&#160;31, 2020, the combined carrying value of these investments was&#160;$13.4 million. Ciena elects to estimate the fair value at cost minus impairment, if any, plus or minus observable price changes in orderly transactions for identical or similar investments of the same issuer. Ciena evaluates these investments for impairment or observable price changes quarterly and records adjustments to interest and other income (loss), net on the Consolidated Statements of Operations.</us-gaap:InvestmentPolicyTextBlock>

The contract is or contains a lease if the contract conveys the right to control the use of the property, plant, or equipment for a designated term in exchange for consideration. Ciena&#x2019;s evaluation of its contracts follows the assessment of whether there is a right to obtain substantially all of the economic benefits from the use and the right to direct the use of the identified asset in the contract. Operating leases are included in the Operating right-of-use assets (&#x201c;Operating ROU assets&#x201d;), Operating lease liabilities and Long-term operating lease liabilities in the Consolidated Balance Sheets. Finance leases are included in Equipment, building, furniture and fixtures, net (&#x201c;Finance ROU assets&#x201d;), Accrued liabilities and other short-term obligations and Other long-term obligations in the Consolidated Balance Sheets.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena has operating and finance leases that primarily relate to real property. Ciena has elected not to capitalize leases with a term of 12 months or less without a purchase option that it is likely to exercise. Ciena has elected not to separate lease and non-lease components of operating and finance leases. Lease components are payment items directly attributable to the use of the underlying asset, while non-lease components are explicit elements of a contract not directly related to the use of the underlying asset, including pass-through operating expenses like common area maintenance and utilities.&lt;/span&gt;&lt;/div&gt;Operating ROU assets and lease liabilities and Finance ROU assets and lease liabilities are recognized on the Consolidated Balance Sheets at the present value of the future lease payments over the life of the lease term. Ciena uses discount rates based on incremental borrowing rates, on a collateralized basis, for the respective underlying assets, for terms similar to the respective leases when implicit rates for leases are not determinable. Operating lease costs are included as rent expense in the Consolidated Statements of Operations. Fixed base payments on operating leases paid directly to the lessor are recorded as lease expense on a straight-line basis. Related variable payments based on usage, changes in an index, or market rate are expensed as incurred. Finance ROU assets are generally amortized on a straight-line basis over the lease term with the interest expense on the lease liability recorded using the interest method. The amortization and interest expense are recorded separately in the Consolidated Statements of Operations.</us-gaap:LesseeLeasesPolicyTextBlock>

The majority of Ciena&#x2019;s cash equivalents consist of money market funds. Deposits held with banks may exceed the amount of insurance provided on such deposits.

The inability of any of these suppliers to fulfill Ciena&#x2019;s supply requirements, or significant changes in supply cost, could affect future results. Ciena relies on a small number of contract manufacturers to perform the majority of the manufacturing for its products.

These purchase orders under framework agreements are used to determine the identification of the contract or contracts with this customer. Purchase orders typically include the description, quantity, and price of each product or service purchased. Purchase orders may include one-line bundled pricing for both products and services. Accordingly, purchase orders can include various combinations of products and services that are generally distinct and accounted for as separate performance obligations. Ciena evaluates each promised product and service offering to determine whether it represents a distinct performance obligation. In doing so, Ciena considers, among other things, customary business practices, whether the customer can benefit from the product or service on its own or together with other resources that are readily available, and whether Ciena&#x2019;s commitment to transfer the product or service to the customer is separately identifiable from other obligations in the purchase order. For transactions where Ciena delivers the product or services, Ciena is typically the principal and records revenue and costs of goods sold on a gross basis.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:3pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Purchase orders are invoiced based on the terms set forth either in the purchase order or the framework agreement, as applicable. Generally, sales of products and software licenses are invoiced upon shipment or delivery. Maintenance and software subscription services are invoiced quarterly or annually in advance of the service term. Ciena&#x2019;s other service offerings are generally invoiced upon completion of the service. Payment terms and cash received typically range from 30 to 90 days from the invoicing date. Historically, Ciena has not provided any material financing arrangements to its customers. As a practical expedient, Ciena does not adjust the amount of consideration it will receive for the effects of a significant financing &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:3pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;component as it expects, at contract inception, that the period between Ciena transfer of the products or services to the customer, and customer payment for the products or services will be one year or less. Shipping and handling fees invoiced to customers are included in revenue, with the associated expense included in product cost of goods sold. Ciena records revenue net of any associated sales taxes.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena recognizes revenue upon the transfer of control of promised products or services to a customer. Transfer of control occurs once the customer has the contractual right to use the product, generally upon shipment or delivery to the customer. Transfer of control can also occur over time for services such as software subscription, maintenance, installation, and various professional services as the customer receives the benefit over the contract term. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Significant Judgments &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Revenue is allocated among performance obligations based on standalone selling price (&#x201c;SSP&#x201d;). SSP reflects the price at which Ciena would expect to sell that product or service on a stand-alone basis at contract inception and that Ciena would expect to be entitled to receive for the promised products or services. SSP is estimated for each distinct performance obligation, and judgment may be required in its determination. The best evidence of SSP is the observable price of a product or service when Ciena sells the products separately in similar circumstances and to similar customers. In instances where SSP is not directly observable, Ciena determines SSP using information that may include market conditions and other observable inputs. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena applies judgment in determining the transaction price, as Ciena may be required to estimate variable consideration when determining the amount of revenue to recognize. Variable consideration can include various rebate, cooperative marketing, and other incentive programs that Ciena offers to its distributors, partners and customers. When determining the amount of revenue to recognize, Ciena estimates the expected usage of these programs, applying the expected value or most likely estimate and updates the estimate at each reporting period as actual utilization data becomes available. Ciena also considers any customer right of return and any actual or potential payment of liquidated damages, contractual or similar penalties, or other claims for performance failures or delays in determining the transaction price, where applicable.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;When transfer of control is judged to be over time for installation and professional service arrangements, Ciena applies the input method to determine the amount of revenue to be recognized in a given period. Utilizing the input method, Ciena recognizes revenue based on the ratio of actual costs incurred to date to the total estimated costs expected to be incurred. Revenue for software subscription and maintenance is recognized ratably over the period during which the services are performed. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Capitalized Contract Acquisition Costs&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena has considered the impact of the guidance in ASC 340-40, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Other Assets and Deferred Costs; Contracts with Customers&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;, and the interpretations of the Financial Accounting Standards Board (&#x201c;FASB&#x201d;) Transition Resource Group for Revenue Recognition with respect to capitalization and amortization of incremental costs of obtaining a contract. In conjunction with this interpretation, Ciena considers each customer purchase in combination with the corresponding framework agreement, if applicable, as a contract. Ciena has elected to implement the practical expedient, which allows for incremental costs to be recognized as an expense when incurred if the period of the asset recognition is one year or less. If the period of the asset recognition is greater than one year, Ciena amortizes these costs over the period of performance. Ciena considers sales commissions incurred upon receipt of purchase orders placed by customers as incremental costs to obtain such purchase orders. The practical expedient method is applied to the purchase order as a whole and thus the capitalized costs of obtaining a purchase order is applied even if the purchase order contains more than one performance obligation. In cases where a purchase order includes various distinct products or services with both short-term (one year or less) and long-term (more than a year) performance periods, the cost of commissions incurred for the total value of the purchase order is capitalized and subsequently amortized as each performance obligation is recognized.&lt;/span&gt;&lt;/div&gt;</us-gaap:RevenueFromContractWithCustomerPolicyTextBlock>

Ciena performs ongoing credit evaluations of its customers and generally has not required collateral or other forms of security from them. In determining the appropriate balance for Ciena&#x2019;s allowance for doubtful accounts receivable, management considers each individual customer account receivable in order to determine collectibility. In doing so, management considers creditworthiness, payment history, account activity and communication with the customer. If a customer&#x2019;s financial condition changes, or if actual defaults are higher than Ciena&#x2019;s historical experience, Ciena may be required to take a charge for an allowance for doubtful accounts receivable, which could have an adverse impact on its results of operations.</us-gaap:ReceivablesPolicyTextBlock>

Ciena estimates the fair value of each option-based award on the date of grant using the Black-Scholes option-pricing model. This model is affected by Ciena&#x2019;s stock price as well as estimates regarding a number of variables, including expected stock price volatility over the expected term of the award and projected employee stock option exercise behaviors. Ciena recognizes the estimated fair value of restricted stock units subject only to service-based vesting conditions by multiplying the number of shares underlying the award by the closing price per share of Ciena common stock on the grant date. In each case, Ciena only recognizes expense in its Consolidated Statement of Operations for those stock options or restricted stock units that are expected ultimately to vest. Awards with performance-based vesting conditions (i) require the achievement of certain operational, financial or other performance criteria or targets or (ii) vest based on Ciena&#x2019;s total shareholder return as compared to an index of peer companies, in whole or in part. Ciena recognizes the estimated fair value of restricted stock units subject to performance-based vesting conditions other than total shareholder return by assuming the satisfaction of any performance-based objectives at the &#x201c;target&#x201d; level and multiplying the corresponding number of shares earned based upon such achievement by the closing price per share of Ciena common stock on the grant date. Ciena recognizes the estimated fair value of performance based awards subject to total shareholder return as compared to an index of peer companies using a Monte Carlo simulation valuation model on the date of grant. At the end of each reporting period, Ciena reassesses the probability of achieving the performance targets and the performance period required to meet those targets.</us-gaap:ShareBasedCompensationOptionAndIncentivePlansPolicy>

Repurchased common stock is reflected as a reduction of stockholders&#x2019; equity. Ciena&#x2019;s accounting policy related to its share repurchases is to reduce its common stock based on the par value of the shares and to reduce its capital surplus for the excess of the repurchase price over the par value. Since the inception of its share repurchase program in December 2018, Ciena has had an accumulated deficit balance; therefore, the excess over the par value has been applied to additional paid-in capital. Once Ciena has retained earnings, the excess will be charged entirely to retained earnings.Due to the continued uncertainty surrounding the duration and severity of potential macroeconomic impacts of COVID-19, Ciena considered it prudent to temporarily suspend purchases of its common stock under its stock repurchase program effective as of March 17, 2020.

This approach recognizes deferred tax assets and liabilities (&#x201c;DTA&#x201d;) for the expected future tax consequences attributable to differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax bases, and for operating loss and tax credit carryforwards. In estimating future tax consequences, Ciena considers all expected future events other than the enactment of changes in tax laws or rates. Valuation allowances are provided if, based on the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In the ordinary course of business, transactions occur for which the ultimate outcome may be uncertain. In addition, tax authorities periodically audit Ciena&#x2019;s income tax returns. These audits examine significant tax filing positions, including the timing and amounts of deductions and the allocation of income tax expenses among tax jurisdictions. Ciena is currently under audit in India for 2012 and 2014 through 2018, in Canada for 2013 through 2015, and in the United Kingdom for 2014 through 2018. Management does not expect the outcome of these audits to have a material adverse effect on Ciena&#x2019;s consolidated financial position, results of operations or cash flows. Ciena&#x2019;s major tax jurisdictions and the earliest open tax years are as follows: United States (2017), United Kingdom (2014), Canada (2013), and India (2012). Limited adjustments can be made to federal U.S. tax returns in earlier years in order to reduce net operating loss carryforwards. Ciena classifies interest and penalties related to uncertain tax positions as a component of income tax expense.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena has not provided for U.S. deferred income taxes on the cumulative unremitted earnings of its non-U.S. affiliates, as it plans to indefinitely reinvest these foreign earnings outside the U.S. As of October&#160;31, 2020, the cumulative amount of such temporary differences for which a deferred tax liability has not been recognized totaled approximately $375.0 million. If these earnings were distributed to the U.S. in the form of dividends, or otherwise, or if the shares of the relevant foreign subsidiaries were sold or otherwise transferred, Ciena would be subject to additional U.S. income taxes (subject to an adjustment for foreign tax credits) and foreign withholding taxes.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena is required to record excess tax benefits or tax deficiencies related to stock-based compensation as income tax benefit or expense when share-based awards vest or are settled. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena adopted ASU 2016-09, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Improvements to Employee Share-Based Payment Accounting, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;in the first quarter of fiscal 2018.

An accounting policy choice is allowed to either treat taxes due on future U.S. inclusions related to GILTI in taxable income as a current-period expense when incurred (the &#x201c;period cost method&#x201d;) or factor such amounts into the measurement of deferred taxes (the &#x201c;deferred method&#x201d;). The calculation of the deferred balance with respect to the GILTI tax provisions will depend, in part, on analyzing global income to determine whether future U.S. inclusions in taxable income are expected related to GILTI and, if so, what the impact is expected to be. Ciena is electing to use the period cost method for future GILTI inclusions. Additionally, Ciena is electing to use the incremental cash tax savings approach when determining whether a valuation allowance needs to be recorded against the U.S. net operating loss (&#x201c;NOL&#x201d;) due to the GILTI inclusions.&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Tax Act also introduced an alternative tax known as the base erosion and anti-abuse tax (&#x201c;BEAT&#x201d;).&#160;An accounting policy choice has been made to consider BEAT as a period cost when incurred.&lt;/span&gt;&lt;/div&gt;</us-gaap:IncomeTaxPolicyTextBlock>

As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.

This hierarchy prioritizes the inputs into three broad levels as follows: &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities; &lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;Level 2 inputs are quoted prices for identical or similar assets or liabilities in less active markets or model-derived valuations in which significant inputs are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; and&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;Level 3 inputs are unobservable inputs based on Ciena&#x2019;s assumptions used to measure assets and liabilities at fair value.

GAAP requires the capitalization of certain software development costs that are incurred subsequent to the date technological feasibility is established and prior to the date the product is generally available for sale. The capitalized cost is then amortized using the straight-line method over the estimated life of the product. Ciena defines technological feasibility as being attained at the time a working model is completed. To date, the period between Ciena achieving technological feasibility and the general availability of such software has been short, and software development costs qualifying for capitalization have been insignificant.

Effective November 3, 2019, Ciena adopted ASC 842, which requires right-of-use ("ROU") assets and lease liabilities to be recorded on the balance sheet, on a modified retrospective basis, such that related amounts in prior periods have not been restated.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;As a practical expedient for disclosure, Ciena has elected the &#x201c;package of practical expedients&#x201d; and, as a result, did not reassess existing lease identifications, lease classifications or initial direct costs. As a practical expedient, Ciena has elected not to capitalize leases with a term of 12 months or less without a purchase option that it is likely to exercise. Also as a practical expedient, Ciena has elected not to separate lease and non-lease components of operating and finance leases. Lease components are payment items directly attributable to the use of the underlying asset, while non-lease components are explicit elements of a contract not directly related to the use of the underlying asset, including pass-through operating expenses like common area maintenance and utilities. In connection with its adoption of ASC 842, Ciena has implemented new accounting policies and processes, and incorporated such into its existing internal control environment as necessary to support the requirements of ASC 842.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Upon adoption, Ciena recorded Operating ROU assets of $53.3&#160;million and lease liabilities of $76.0&#160;million related to its operating leases. As of November&#160;2, 2019, the restructuring reserve liability for vacated office space of $11.1&#160;million was included in Accrued liabilities and other short-term obligations and Other long-term obligations on the Consolidated Balance Sheet under prior accounting guidance. Upon adoption of ASC 842, the existing lease reserve liability was reclassified as a reduction to the Operating ROU assets. ROU assets will be tested for impairment when circumstances indicate that the carrying &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;values may not be recoverable.

The new standard replaces the incurred loss impairment model. Under this standard, Ciena will be required to use a forward-looking expected credit loss model for accounts receivable, contract assets, and other financial instruments. ASU 2016-13 is effective for Ciena beginning in the first quarter of fiscal 2021 on a modified retrospective basis with the cumulative effect of adoption recorded as an adjustment to retained earnings. This standard will not have a material impact on Ciena&#x2019;s Consolidated Financial Statements and disclosures at adoption.&lt;/span&gt;&lt;/div&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The acquisition of DonRiver included a $28.5 million three-year earn-out arrangement that consisted of both a contingent consideration element and a contingent compensation element. The contingent consideration element required additional cash consideration to be paid based on the future revenues generally derived from the DonRiver business over a 25-month period from the acquisition date through October 31, 2020. The undiscounted amounts potentially payable by Ciena under the contingent consideration element ranged from $0.0 million to $15.0 million in the aggregate over the period. The $10.9 million fair value of the contingent consideration element as of the acquisition date was estimated by applying the income approach based on a discounted cash flow technique using Monte Carlo simulations. See Note 7 below. The contingent compensation element of the earn-out arrangement included an employment condition for the selling shareholders who became employees of Ciena upon the completion of the acquisition. The range of amounts that Ciena could pay under the contingent compensation element is between $0.0 million and $13.5 million in the aggregate over the period. These amounts are accrued over the period earned and recorded as expense in the acquisition and integration costs line item in the Consolidated Statement of Operations. During fiscal 2020, fiscal 2019 and fiscal 2018, Ciena recorded $6.9&#160;million, $5.1 million and $0.4 million, of contingent compensation associated with the earn-out arrangement, respectively.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The contingent consideration liability established at closing had an acquisition date fair value of $10.9 million. As of November 2, 2019, the fair value of the contingent consideration liability was $8.1&#160;million. During fiscal 2020 and fiscal 2019, decreases of $3.7&#160;million and $2.8&#160;million, respectively, were recorded as reductions to expense in the acquisition and integration cost line item in the Consolidated Statement of Operations. During fiscal 2019, $4.4&#160;million of the total contingent consideration liability was earned. This payment was paid during the first quarter of fiscal 2020. As of October&#160;31, 2020, no contingent consideration liability remained.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; Customer relationships and contracts represent agreements with existing DonRiver customers. Customer relationships and contracts are amortized on a straight-line basis over their estimated useful life of seven years. Fair value was determined using the multi-period excess earnings method&#160;based on the present value of the incremental after-tax cash flows (or &#x201c;excess earnings&#x201d;) attributable to customer relationships for a discrete projection period.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Developed technology represents purchased technology that had reached technological feasibility and for which DonRiver had substantially completed development as of the date of acquisition. Fair value was determined using future discounted cash flows related to the projected income stream of the developed technology for a discrete projection period. Cash flows were discounted to their present value as of the closing date. Developed technology is amortized on a straight-line basis over its estimated useful life of seven years.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The goodwill generated from the acquisition of DonRiver is primarily related to expected synergies. The total goodwill amount was recorded in the previous Software and Software-Related Services segment.

currency; however, some of its foreign branch offices and subsidiaries use the local currency as their functional currency. During fiscal 2020, 2019 and 2018, Ciena recorded $13.0 million, $9.8 million and $19.4 million, respectively, in exchange rate losses, as a result of monetary assets and liabilities that were transacted in a currency other than the entity&#x2019;s functional currency, and the related remeasurement adjustments were recorded in interest and other income (loss), net. From time to time, Ciena uses foreign currency forwards to hedge these balance sheet exposures. These forwards are not designated as hedges for accounting purposes, and any net gain or loss associated with these derivatives is also reported in interest and other income (loss), net. During fiscal 2019, Ciena recorded minimal gains from non-hedge designated foreign currency forward contracts. For fiscal 2020 and fiscal 2018, Ciena recorded gains of $5.6 million and $6.8 million, respectively, from non-hedge designated foreign currency forward contracts.</us-gaap:OtherNonoperatingIncomeAndExpenseTextBlock>

during the periods presented.As of October&#160;31, 2020, none of Ciena&#x2019;s existing liabilities were classified as Level 3. As of November&#160;2, 2019, Ciena&#x2019;s Level 3 liability included $3.7 million in accrued liabilities and other short-term obligations. This reflected a contingent consideration element of a three-year payout arrangement associated with Ciena&#x2019;s purchase of DonRiver in the fourth quarter of fiscal 2018. During the third quarter of fiscal 2020, the total contingent consideration liability was recorded as a reduction to expense in acquisition and integration costs on the Consolidated Statements of Operations to reflect the fair value of the consideration using the income approach. No contingent consideration liability remains in Other long-term obligations on the Consolidated Balance Sheets as of October&#160;31, 2020.</us-gaap:FairValueDisclosuresTextBlock>

As of November&#160;2, 2019, one customer accounted for 12.0% of net accounts receivable. Ciena has not historically experienced a significant amount of bad debt expense.

for estimated obsolescence or unmarketable inventory by an amount equal to the difference between the cost of inventory and the estimated net realizable value based on assumptions about future demand, which are affected by changes in Ciena&#x2019;s strategic direction, discontinuance of a product or introduction of newer versions of products, declines in the sales of or forecasted demand for certain products, and general market conditions. During fiscal 2020, fiscal 2019 and fiscal 2018, Ciena recorded a provision for excess and obsolescence of $24.7 million, $28.1 million, and $30.6 million, respectively, primarily related to a decrease in the forecasted demand for certain Networking Platforms products.

carrying amount of the term loan totaled $2.9 million at October&#160;31, 2020 and $3.6 million at November&#160;2, 2019. Deferred debt issuance costs are amortized using the straight-line method, which approximates the effect of the effective interest rate method, through the maturity of the term loan. The amortization of deferred debt issuance costs for this term loan is included in interest expense, and was $0.6 million during each of fiscal 2020 and fiscal 2019.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:3pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;As of October&#160;31, 2020, the estimated fair value of the term loan was $686.1 million. Ciena&#x2019;s term loan is categorized as Level 2 in the fair value hierarchy.

In connection with the transaction, Ciena received a loan in the amount of $699.1&#160;million, net of original discount, from the Old 2025 Term Loan and simultaneously repaid $394.0&#160;million of outstanding principal under the 2022 Term Loan, resulting in proceeds of $305.1&#160;million. On January 23, 2020, Ciena entered into a Refinancing Amendment to Credit Agreement pursuant to which Ciena refinanced the entire outstanding amount of the Old 2025 Term Loan with an outstanding aggregate principal amount of $693.0&#160;million as of January 23, 2020 and incurred a new senior secured term loan in an aggregate principal amount of $693.0&#160;million and maturing on September 28, 2025 (the &#x201c;New 2025 Term Loan&#x201d;). The New 2025 Term Loan requires Ciena to make installment payments of $1.73&#160;million on a quarterly basis. Based on the continuation of existing lenders, this arrangement was primarily accounted for as a modification of debt and, as such, $0.4&#160;million of debt issuance costs associated with the New 2025 Term Loan were expensed.

The program may be modified, suspended, or discontinued at any time. Due to the continued uncertainty surrounding the duration and severity of potential macroeconomic impacts of COVID-19, Ciena considered it prudent to temporarily suspend purchases of its common stock under its stock repurchase program effective as of March 17, 2020. The reinstatement of the program and the amount and timing of repurchases are subject to a variety of factors including liquidity, cash flow, stock price, and general business and market

style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;On December 22, 2017, the Tax Act was enacted. The Tax Act significantly revised the U.S. corporate income tax by, among other things, lowering the statutory corporate income tax rate (&#x201c;federal tax rate&#x201d;) from 35% to 21% effective January 1, 2018, implementing a modified territorial tax system, and imposing a mandatory one-time transition tax on accumulated earnings of foreign subsidiaries. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;As a result of the decrease in the federal tax rate from 35% to 21% effective January 1, 2018, Ciena computed its income tax expense for the November 3, 2018 fiscal year using a blended federal tax rate of&#160;23.41%. Ciena remeasured its DTA using the federal tax rate that will apply when the related temporary differences are expected to reverse.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Our future income tax provisions and deferred tax balances may be affected by the amount of pre-tax income, the jurisdictions where it is earned, the existence and utilizability of tax attributes, changes in tax laws and business reorganizations. Ciena continues to monitor these items and will adopt strategies to address their impact as appropriate.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In December 2017, the SEC issued Staff Accounting Bulletin No. 118, which addresses how a company recognizes provisional amounts when it does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the effect of the changes due to the Tax Act. The measurement period ends when a company has obtained, prepared and analyzed the information necessary to finalize its accounting, but cannot extend beyond one year. The final impact of the Tax Act may differ from the above amounts to the extent they are provisional due to changes in interpretations of the Tax Act, legislative action to address questions that arise because of the Tax Act, changes in accounting standards for income taxes and related interpretations in response to the Tax Act, and any updates or changes to estimates used in the provisional amounts. The enactment of the Tax Act resulted in Ciena recording a provisional tax expense of $472.8 million in fiscal 2018. In the first quarter of fiscal 2019, the measurement period under the Tax Act concluded, which resulted in immaterial adjustments to Ciena&#x2019;s provisional estimates.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena is also required to make accounting policy elections as a result of the Tax Act.&#160;These include whether a valuation allowance is recorded for the estimated effect of the application of GILTI and BEAT or if these will be treated as period costs when incurred.&#160;Ciena had made the incremental cash tax cost policy election with respect to analyzing the impact of GILTI on the assessment of the realizability of net operating losses. The realizability of U.S. tax carryforwards is not impacted by the BEAT, and the BEAT is a period cost when incurred. Ciena is also required to elect to either treat taxes due on future GILTI inclusions in U.S. taxable income as a current period expense when incurred or reflect such portion of the future GILTI inclusions in U.S. taxable income that relate to existing basis differences in Ciena&#x2019;s current measurement of deferred taxes.&#160;Ciena&#x2019;s accounting policy election is to treat the taxes due on future U.S. inclusions in taxable income under GILTI as a period cost when incurred.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span

and $3.0 million of interest and penalties, respectively, related to unrecognized tax benefits within other long-term liabilities in the Consolidated Balance Sheets. Interest and penalties of $0.9 million and $1.1 million were recorded as an expense to the provision for income taxes during fiscal 2020 and fiscal 2018, respectively. During fiscal 2019, Ciena recorded a provision for interest and penalties in its provision for income taxes of $1.0&#160;million. If recognized, the entire balance of unrecognized tax benefits would impact the effective tax rate. Over the next 12&#160;months, Ciena does not estimate any material changes in unrecognized income tax benefits.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena has not provided for U.S. deferred income taxes on the cumulative unremitted earnings of its non-U.S. affiliates, as it plans to indefinitely reinvest these foreign earnings outside the U.S. As of October&#160;31, 2020, the cumulative amount of such temporary differences for which a deferred tax liability has not been recognized is an estimated $375.0 million. If these earnings were distributed to the U.S., Ciena would be subject to additional foreign withholding taxes of approximately $25.0 million. Additionally, there are no other significant temporary differences for which a deferred tax liability has not been recognized.&lt;/span&gt;&lt;/div&gt;&lt;div

All equity awards granted on or after March 23, 2017 are made exclusively from the 2017 Plan. Ciena also makes shares of its common stock available for purchase under its Amended and Restated 2003 Employee Stock Purchase Plan (the &#x201c;ESPP&#x201d;). Each of the 2017 Plan and the ESPP are described below.&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;2017 Plan&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The 2017 Plan has a ten-year term and authorizes the issuance of awards including stock options, restricted stock units (RSUs), restricted stock, unrestricted stock, stock appreciation rights (SARs) and other equity and/or cash performance incentive awards to employees, directors and consultants of Ciena. Subject to certain restrictions, the Compensation Committee of the Board of Directors has broad discretion to establish the terms and conditions for awards under the 2017 Plan, including the number of shares, vesting conditions, and the required service or performance criteria. Options and SARs have a maximum term of ten years, and their exercise price may not be less than 100% of fair market value on the date of grant. Repricing of stock options and SARs is prohibited without stockholder approval. Certain change in control transactions may cause awards granted under the 2017 Plan to vest, unless the awards are continued or substituted for in connection with the transaction. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;At Ciena&#x2019;s 2020 Annual Meeting of Stockholders on April 2, 2020, Ciena&#x2019;s stockholders approved an amendment to the 2017 Plan to increase the number of shares available for issuance thereunder by 12.2&#160;million shares, which became effective as of such date. The 2017 Plan authorizes and reserves 21.1 million shares for issuance. In addition, any shares that remained available for issuance under the 2008 Plan as of March 23, 2017 were added to the 2017 Plan and are available for issuance thereunder. The number of shares available under the 2017 Plan will also be increased from time to time by: (i)&#160;the number of shares subject to outstanding awards granted under Ciena&#x2019;s prior equity compensation plans that are forfeited, expire or are canceled without delivery of common stock following the effective date of the 2017 Plan, and (ii)&#160;the number of shares subject to awards assumed or substituted in connection with the acquisition of another company. As of October&#160;31, 2020, the total number of shares authorized for issuance under the 2017 Plan was 21.1 million and approximately 14.7 million shares remained available for issuance thereunder.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Stock Options&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;There were no stock options granted by Ciena during fiscal 2020, fiscal 2019 or fiscal 2018.

At the end of each reporting period, Ciena reassesses the probability of achieving the performance targets and the performance period required to meet those targets. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena recognizes the estimated fair value of restricted stock units subject only to service-based vesting conditions by multiplying the number of shares underlying the award by the closing price per share of Ciena common stock on the grant date. Ciena recognizes the estimated fair value of restricted stock units subject to performance-based vesting conditions other than total shareholder return by assuming the satisfaction of any performance-based objectives at the &#x201c;target&#x201d; level and multiplying the corresponding number of shares earned based upon such achievement by the closing price per share of Ciena common stock on the grant date. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena recognizes the estimated fair value of performance based awards subject to total shareholder return as compared to an index of peer companies using a Monte Carlo simulation valuation model.

are performance based awards subject to total shareholder return, respectively. The total fair value of restricted stock units that vested and were converted into common stock during fiscal 2020, fiscal 2019 and fiscal 2018 was $83.5 million, $79.2 million and $54.3 million, respectively. The weighted average fair value of each restricted stock unit granted by Ciena during fiscal 2020, fiscal 2019 and fiscal 2018 was $41.61, $34.53 and $22.46, respectively. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The fair value of each restricted stock unit award is based on the closing price on the date of grant. Share-based expense for service-based restricted stock unit awards is recognized ratably over the vesting period on a straight-line basis. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Share-based expense for performance-based restricted stock unit awards is recognized ratably over the performance period based on Ciena&#x2019;s determination of whether it is probable that the performance targets will be achieved. At each reporting period, Ciena reassesses the probability of achieving the performance targets and the performance period required to meet those targets. The estimation of whether the performance targets will be achieved involves judgment, and the estimate of expense is revised periodically based on the probability of achieving the performance targets. Revisions are reflected in the period in which the estimate is changed. If any performance goals are not met, no compensation cost is ultimately recognized against that goal and, to the extent previously recognized, compensation expense is reversed. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Share-based compensation expense is recognized only for those awards that are ultimately expected to vest. In the event of a forfeiture of an award, the expense related to the unvested portion of that award is reversed. Reversal of share-based compensation expense based on forfeitures can materially affect the measurement of estimated fair value of Ciena&#x2019;s share-based compensation.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Amended and Restated ESPP&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Under the ESPP, eligible employees may enroll in a twelve-month offer period that begins in December&#160;and June&#160;of each year. Each offer period includes two six-month purchase periods. Employees may purchase a limited number of shares of Ciena common stock at 85% of the fair market value on either the day immediately preceding the offer date or the purchase date, whichever is lower. The ESPP is considered compensatory for purposes of share-based compensation expense. Pursuant to the ESPP&#x2019;s &#x201c;evergreen&#x201d; provision, on December&#160;31 of each year, the number of shares available under the ESPP increases by up to 0.6 million shares, provided that the total number of shares available at that time shall not exceed 8.2 million.

Under these agreements, Ciena can receive up to an aggregate CAD$57.6 million (approximately $43.2 million) in reimbursement from the three Canadian government entities for eligible costs over a period commencing on February 20, 2017 and ending on March 31, 2022.

Fiscal 2020 and fiscal 2019 each consisted of a 52-week fiscal year and fiscal 2018 consisted of a 53-week fiscal year. Effective the second quarter of fiscal 2020, Ciena changed the presentation of reporting for its financial statements and notes thereto to reflect the actual dates on which fiscal years ended. Because these dates can change from period to period, for consistency purposes, Ciena previously presented such information indicating that its fiscal years ended on October&#160;31.

The excess of the purchase price over the estimated fair values of the net tangible and net intangible assets acquired is recorded as goodwill. The application of the purchase method of accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed, in order to properly allocate purchase price consideration between assets that are depreciated and amortized from goodwill. These assumptions and estimates include a market participant&#8217;s use of the asset and the appropriate discount rates for a market </span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">participant.

Ciena recognizes losses in the income statement when it determines that declines in the fair value of its investments below their cost basis are other-than-temporary. In determining whether a decline in fair value is other-than-temporary, Ciena considers various factors, including market price (when available), investment ratings, the financial condition and near-term prospects of the investee, the length of time and the extent to which the fair value has been less than Ciena&#8217;s cost basis, and Ciena&#8217;s intent and ability to hold the investment until maturity or for a period of time sufficient to allow for any anticipated recovery in market value.

As of&#160;October&#160;31, 2020, the combined carrying value of these investments was&#160;$13.4 million. Ciena elects to estimate the fair value at cost minus impairment, if any, plus or minus observable price changes in orderly transactions for identical or similar investments of the same issuer.

Ciena tests goodwill for impairment on an annual basis, which it has determined to be the last business day of fiscal September each year.

If this test indicates that the fair value is less than the carrying value, then an impairment loss is recognized limited to the total amount of goodwill allocated to that reporting unit. A non-cash goodwill impairment charge would have the effect of decreasing earnings or increasing losses in such period.

These purchase orders under framework agreements are used to determine the identification of the contract or contracts with this customer. Purchase orders typically include the description, quantity, and price of each product or service purchased. Purchase orders may include one-line bundled pricing for both products and services. Accordingly, purchase orders can include various combinations of products and services that are generally distinct and accounted for as separate performance obligations. Ciena evaluates each promised product and service offering to determine whether it represents a distinct performance obligation. In doing so, Ciena considers, among other things, customary business practices, whether the customer can benefit from the product or service on its own or together with other resources that are readily available, and whether Ciena&#8217;s commitment to transfer the product or service to the customer is separately identifiable from other obligations in the purchase order.

SSP is estimated for each distinct performance obligation, and judgment may be required in its determination. The best evidence of SSP is the observable price of a product or service when Ciena sells the products separately in similar circumstances and to similar customers.

In conjunction with this interpretation, Ciena considers each customer purchase in combination with the corresponding framework agreement, if applicable, as a contract. Ciena has elected to implement the practical expedient, which allows for incremental costs to be recognized as an expense when incurred if the period of the asset recognition is one year or less. If the period of the asset recognition is greater than one year, Ciena amortizes these costs over the period of performance. Ciena considers sales commissions incurred upon receipt of purchase orders placed by customers as incremental costs to obtain such purchase orders. The practical expedient method is applied to the purchase order as a whole and thus the capitalized costs of obtaining a purchase order is applied even if the purchase order contains more than one performance obligation. In cases where a purchase order includes various distinct products or services with both short-term (one year or less) and long-term (more than a year) performance periods, the cost of commissions incurred for the total value of the purchase order is capitalized and subsequently amortized as each performance obligation is recognized.</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For the additional disclosures on capitalized contract acquisition costs, see Note 2 below.</span></div><div style="text-indent:18pt"><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Warranty Accruals</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Ciena provides for the estimated costs to fulfill customer warranty obligations upon recognition of the related revenue.

In doing so, management considers creditworthiness, payment history, account activity and communication with the customer.

Ciena estimates the fair value of each option-based award on the date of grant using the Black-Scholes option-pricing model. This model is affected by Ciena&#8217;s stock price as well as estimates regarding a number of variables, including expected stock price volatility over the expected term of the award and projected employee stock option exercise behaviors. Ciena recognizes the estimated fair value of restricted stock units subject only to service-based vesting conditions by multiplying the number of shares underlying the award by the closing price per share of Ciena common stock on the grant date. In each case, Ciena only recognizes expense in its Consolidated Statement of Operations for those stock options or restricted stock units that are expected ultimately to vest. Awards with performance-based vesting conditions (i) require the achievement of certain operational, financial or other performance criteria or targets or (ii) vest based on Ciena&#8217;s total shareholder return as compared to an index of peer companies, in whole or in part. Ciena recognizes the estimated fair value of restricted stock units subject to performance-based vesting conditions other than total shareholder return by assuming the satisfaction of any performance-based objectives at the &#8220;target&#8221; level and multiplying the corresponding number of shares earned based upon such achievement by the closing price per share of Ciena common stock on the grant date. Ciena recognizes the estimated fair value of performance based awards subject to total shareholder return as compared to an index of peer companies using a Monte Carlo simulation valuation model on the date of grant.

This approach recognizes deferred tax assets and liabilities (&#8220;DTA&#8221;) for the expected future tax consequences attributable to differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax bases, and for operating loss and tax credit carryforwards. In estimating future tax consequences, Ciena considers all expected future events other than the enactment of changes in tax laws or rates. Valuation allowances are provided if, based on the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In the ordinary course of business, transactions occur for which the ultimate outcome may be uncertain. In addition, tax authorities periodically audit Ciena&#8217;s income tax returns. These audits examine significant tax filing positions, including the timing and amounts of deductions and the allocation of income tax expenses among tax jurisdictions. Ciena is currently under audit in India for 2012 and 2014 through 2018, in Canada for 2013 through 2015, and in the United Kingdom for 2014 through 2018. Management does not expect the outcome of these audits to have a material adverse effect on Ciena&#8217;s consolidated financial position, results of operations or cash flows. Ciena&#8217;s major tax jurisdictions and the earliest open tax years are as follows: United States (2017), United Kingdom (2014), Canada (2013), and India (2012). Limited adjustments can be made to federal U.S. tax returns in earlier years in order to reduce net operating loss carryforwards.

An accounting policy choice is allowed to either treat taxes due on future U.S. inclusions related to GILTI in taxable income as a current-period expense when incurred (the &#8220;period cost method&#8221;) or factor such amounts into the measurement of deferred taxes (the &#8220;deferred method&#8221;).

Ciena is electing to use the period cost method for future GILTI inclusions.

consideration element and a contingent compensation element. The contingent consideration element required additional cash consideration to be paid based on the future revenues generally derived from the DonRiver business over a 25-month period from the acquisition date through October 31, 2020. The undiscounted amounts potentially payable by Ciena under the contingent consideration element ranged from $0.0 million to $15.0 million in the aggregate over the period. The $10.9 million fair value of the contingent consideration element as of the acquisition date was estimated by applying the income approach based on a discounted cash flow technique using Monte Carlo simulations. See Note 7 below. The contingent compensation element of the earn-out arrangement included an employment condition for the selling shareholders who became employees of Ciena upon the completion of the acquisition. The range of amounts that Ciena could pay under the contingent compensation element is between $0.0 million and $13.5 million in the aggregate over the period. These amounts are accrued over the period earned and recorded as expense in the acquisition and integration costs line item in the Consolidated Statement of Operations. During fiscal 2020, fiscal 2019 and fiscal 2018, Ciena recorded $6.9&#160;million, $5.1 million and $0.4 million, of contingent compensation associated with the earn-out arrangement, respectively.</span></div><div style="margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The contingent consideration liability established at closing had an acquisition date fair value of $10.9 million.

During fiscal 2019, $4.4&#160;million of the total contingent consideration liability was earned. This payment was paid during the first quarter of fiscal 2020.

offices and subsidiaries use the local currency as their functional currency. During fiscal 2020, 2019 and 2018, Ciena recorded $13.0 million, $9.8 million and $19.4 million, respectively, in exchange rate losses, as a result of monetary assets and liabilities that were transacted in a currency other than the entity&#8217;s functional currency, and the related remeasurement adjustments were recorded in interest and other income (loss), net. From time to time, Ciena uses foreign currency forwards to hedge these balance sheet exposures. These forwards are not designated as hedges for accounting purposes, and any net gain or loss associated with these derivatives is also reported in interest and other income (loss), net. During fiscal 2019, Ciena recorded minimal gains from non-hedge designated foreign currency forward contracts. For fiscal 2020 and fiscal 2018, Ciena recorded gains of $5.6 million and $6.8 million, respectively, from non-hedge designated foreign currency forward contracts.<span></span>

transfers between Level 1 and Level 2 fair value measurements during the periods presented.As of October&#160;31, 2020, none of Ciena&#8217;s existing liabilities were classified as Level 3. As of November&#160;2, 2019, Ciena&#8217;s Level 3 liability included $3.7 million in accrued liabilities and other short-term obligations. This reflected a contingent consideration element of a three-year payout arrangement associated with Ciena&#8217;s purchase of DonRiver in the fourth quarter of fiscal 2018. During the third quarter of fiscal 2020, the total contingent consideration liability was recorded as a reduction to expense in acquisition and integration costs on the Consolidated Statements of Operations to reflect the fair value of the consideration using the income approach. No contingent consideration liability remains in Other long-term obligations on the Consolidated Balance Sheets as of October&#160;31, 2020.<span></span>

introduction of newer versions of products, declines in the sales of or forecasted demand for certain products, and general market conditions. During fiscal 2020, fiscal 2019 and fiscal 2018, Ciena recorded a provision for excess and obsolescence of $24.7 million, $28.1 million, and $30.6 million, respectively, primarily related to a decrease in the forecasted demand for certain Networking Platforms products.

The program may be modified, suspended, or discontinued at any time. Due to the continued uncertainty surrounding the duration and severity of potential macroeconomic impacts of COVID-19, Ciena considered it prudent to temporarily suspend purchases of its common stock under its stock repurchase program effective as of March 17, 2020. The reinstatement of the program and the amount and timing of repurchases are subject to a variety of factors including liquidity, cash flow, stock price, and general business and market conditions.</span></div><div style="margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The following

enacted. The Tax Act significantly revised the U.S. corporate income tax by, among other things, lowering the statutory corporate income tax rate (&#8220;federal tax rate&#8221;) from 35% to 21% effective January 1, 2018, implementing a modified territorial tax system, and imposing a mandatory one-time transition tax on accumulated earnings of foreign subsidiaries. </span></div><div style="margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">As a result of the decrease in the federal tax rate from 35% to 21% effective January 1, 2018, Ciena computed its income tax expense for the November 3, 2018 fiscal year using a blended federal tax rate of&#160;23.41%.

The measurement period ends when a company has obtained, prepared and analyzed the information necessary to finalize its accounting, but cannot extend beyond one year. The final impact of the Tax Act may differ from the above amounts to the extent they are provisional due to changes in interpretations of the Tax Act, legislative action to address questions that arise because of the Tax Act, changes in accounting standards for income taxes and related interpretations in response to the Tax Act, and any updates or changes to estimates used in the provisional amounts. The enactment of the Tax Act resulted in Ciena recording a provisional tax expense of $472.8 million in fiscal 2018. In the first quarter of fiscal 2019, the measurement period under the Tax Act concluded, which resulted in immaterial adjustments to Ciena&#8217;s provisional estimates.</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Ciena is also required to make accounting policy elections as a result of the Tax Act.&#160;These include whether a valuation allowance is recorded for the estimated effect of the application of GILTI and BEAT or if these will be treated as period costs when incurred.&#160;Ciena had made the incremental cash tax cost policy election with respect to analyzing the impact of GILTI on the assessment of the realizability of net operating losses. The realizability of U.S. tax carryforwards is not impacted by the BEAT, and the BEAT is a period cost when incurred. Ciena is also required to elect to either treat taxes due on future GILTI inclusions in U.S. taxable income as a current period expense when incurred or reflect such portion of the future GILTI inclusions in U.S. taxable income that relate to existing basis differences in Ciena&#8217;s current measurement of deferred taxes.&#160;Ciena&#8217;s accounting policy election is to treat the taxes

All equity awards granted on or after March 23, 2017 are made exclusively from the 2017 Plan. Ciena also makes shares of its common stock available for purchase under its Amended and Restated 2003 Employee Stock Purchase Plan (the &#8220;ESPP&#8221;).

Subject to certain restrictions, the Compensation Committee of the Board of Directors has broad discretion to establish the terms and conditions for awards under the 2017 Plan, including the number of shares, vesting conditions, and the required service or performance criteria. Options and SARs have a maximum term of ten years, and their exercise price may not be less than 100% of fair market value on the date of grant. Repricing of stock options and SARs is prohibited without stockholder approval. Certain change in control transactions may cause awards granted under the 2017 Plan to vest, unless the awards are continued or substituted for in connection with the transaction. </span></div><div style="margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">At Ciena&#8217;s 2020 Annual Meeting of Stockholders on April 2, 2020, Ciena&#8217;s stockholders approved an amendment to the 2017 Plan to increase the number of shares available for issuance thereunder by 12.2&#160;million shares, which became effective as of such date. The 2017 Plan authorizes and reserves 21.1 million shares for issuance. In addition, any shares that remained available for issuance under the 2008 Plan as of March 23, 2017 were added to the 2017 Plan and are available for issuance thereunder. The number of shares available under the 2017 Plan will also be increased from time to time by: (i)&#160;the number of shares subject to outstanding awards granted under Ciena&#8217;s prior equity compensation plans that are forfeited, expire or are canceled without delivery of common stock following the effective date of the 2017 Plan, and (ii)&#160;the number of shares subject to awards assumed or substituted in connection with the acquisition of another company.

At each reporting period, Ciena reassesses the probability of achieving the performance targets and the performance period required to meet those targets. The estimation of whether the performance targets will be achieved involves judgment, and the estimate of expense is revised periodically based on the probability of achieving the performance targets. Revisions are reflected in the period in which the estimate is changed. If any performance goals are not met, no compensation cost is ultimately recognized against that goal and, to the extent previously recognized, compensation expense is reversed. </span></div><div style="margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Share-based compensation expense is recognized only for those awards that are ultimately expected to vest.

Under these agreements, Ciena can receive up to an aggregate CAD$57.6 million (approximately $43.2 million) in reimbursement from the three Canadian government entities for eligible costs over a period commencing on February 20, 2017 and ending on March 31, 2022.

<td class="text">Ciena records acquisitions using the purchase method of accounting. All of the assets acquired, liabilities assumed, contractual contingencies and contingent consideration are recognized at their fair value as of the acquisition date. The excess of the purchase price over the estimated fair values of the net tangible and net intangible assets acquired is recorded as goodwill. The application of the purchase method of accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed, in order to properly allocate purchase price consideration between assets that are depreciated and amortized from goodwill. These assumptions and estimates include a market participant&#8217;s use of the asset and the appropriate discount rates for a market participant. Ciena&#8217;s estimates are based on historical experience, information obtained from the management of the acquired companies and, when appropriate, include assistance from independent third-party appraisal firms. Significant assumptions and estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted-average cost of capital and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable. In addition, unanticipated events and circumstances may occur which may affect the accuracy or validity of such estimates.<span></span>

Ciena recognizes losses in the income statement when it determines that declines in the fair value of its investments below their cost basis are other-than-temporary. In determining whether a decline in fair value is other-than-temporary, Ciena considers various factors, including market price (when available), investment ratings, the financial condition and near-term prospects of the investee, the length of time and the extent to which the fair value has been less than Ciena&#8217;s cost basis, and Ciena&#8217;s intent and ability to hold the investment until maturity or for a period of time sufficient to allow for any anticipated recovery in market value. Ciena considers all marketable debt securities that it expects to convert to cash within one year or less to be short-term investments, with all others considered to be long-term investments.Ciena has minority equity investments in privately held technology companies that are classified in other long-term assets. These investments are carried at cost because Ciena owns less than 20% of the voting equity and does not have the ability to exercise significant influence over the company. Ciena monitors these investments for impairment and makes appropriate reductions to the carrying value when necessary. As of&#160;October&#160;31, 2020, the combined carrying value of these investments was&#160;$13.4 million. Ciena elects to estimate the fair value at cost minus impairment, if any, plus or minus observable price changes in orderly transactions for identical or similar investments of the same issuer. Ciena evaluates these investments for impairment or observable price changes quarterly and records adjustments to interest and other income (loss), net on the Consolidated Statements of Operations.<span></span>

These purchase orders under framework agreements are used to determine the identification of the contract or contracts with this customer. Purchase orders typically include the description, quantity, and price of each product or service purchased. Purchase orders may include one-line bundled pricing for both products and services. Accordingly, purchase orders can include various combinations of products and services that are generally distinct and accounted for as separate performance obligations. Ciena evaluates each promised product and service offering to determine whether it represents a distinct performance obligation. In doing so, Ciena considers, among other things, customary business practices, whether the customer can benefit from the product or service on its own or together with other resources that are readily available, and whether Ciena&#8217;s commitment to transfer the product or service to the customer is separately identifiable from other obligations in the purchase order. For transactions where Ciena delivers the product or services, Ciena is typically the principal and records revenue and costs of goods sold on a gross basis.</span></div><div style="text-indent:13.5pt"><span><br/></span></div><div style="margin-top:3pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Purchase orders are invoiced based on the terms set forth either in the purchase order or the framework agreement, as applicable.

SSP is estimated for each distinct performance obligation, and judgment may be required in its determination. The best evidence of SSP is the observable price of a product or service when Ciena sells the products separately in similar circumstances and to similar customers.

In conjunction with this interpretation, Ciena considers each customer purchase in combination with the corresponding framework agreement, if applicable, as a contract. Ciena has elected to implement the practical expedient, which allows for incremental costs to be recognized as an expense when incurred if the period of the asset recognition is one year or less. If the period of the asset recognition is greater than one year, Ciena amortizes these costs over the period of performance. Ciena considers sales commissions incurred upon receipt of purchase orders placed by customers as incremental costs to obtain such purchase orders. The practical expedient method is applied to the purchase order as a whole and thus the capitalized costs of obtaining a purchase order is applied even if the purchase order contains more than one performance obligation. In cases where a purchase order includes various distinct products or services with both short-term (one year or less) and long-term (more than a year) performance periods, the cost of commissions incurred for the total value of the purchase order is capitalized and subsequently amortized as each performance obligation is recognized.</span></div><span></span>

<td class="text">Ciena measures and recognizes compensation expense for share-based awards based on estimated fair values on the date of grant. Ciena estimates the fair value of each option-based award on the date of grant using the Black-Scholes option-pricing model. This model is affected by Ciena&#8217;s stock price as well as estimates regarding a number of variables, including expected stock price volatility over the expected term of the award and projected employee stock option exercise behaviors. Ciena recognizes the estimated fair value of restricted stock units subject only to service-based vesting conditions by multiplying the number of shares underlying the award by the closing price per share of Ciena common stock on the grant date. In each case, Ciena only recognizes expense in its Consolidated Statement of Operations for those stock options or restricted stock units that are expected ultimately to vest. Awards with performance-based vesting conditions (i) require the achievement of certain operational, financial or other performance criteria or targets or (ii) vest based on Ciena&#8217;s total shareholder return as compared to an index of peer companies, in whole or in part. Ciena recognizes the estimated fair value of restricted stock units subject to performance-based vesting conditions other than total shareholder return by assuming the satisfaction of any performance-based objectives at the &#8220;target&#8221; level and multiplying the corresponding number of shares earned based upon such achievement by the closing price per share of Ciena common stock on the grant date. Ciena recognizes the estimated fair value of performance based awards subject to total shareholder return as compared to an index of peer companies using a Monte Carlo simulation valuation model on the date of grant.
