related disclosures in conformity with accounting principles generally accepted in the United States of America (&#8220;GAAP&#8221;) requires Ciena to make judgments, assumptions, and estimates that affect the amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. The inputs into certain of Ciena&#8217;s judgments, assumptions, and estimates reflect, among other things, the information available to Ciena regarding the economic implications of the COVID-19 pandemic, and expectations as to its impact on Ciena&#8217;s business. Among other things, these estimates form the basis for judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions. To the extent that there are material differences between Ciena&#8217;s estimates and actual results, Ciena&#8217;s consolidated financial statements will be affected. In addition, because the duration and severity of COVID-19 pandemic are uncertain, certain of these estimates could require further judgment or modification and therefore carry a higher degree of variability and volatility. As events continue to evolve, Ciena&#8217;s estimates may change materially in future periods.</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%">In the opinion of management, the financial statements included in this report reflect all normal recurring adjustments that Ciena considers necessary for the fair statement of the results of operations of Ciena for the interim periods covered and of the financial position of Ciena at the date of the interim balance sheets. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with GAAP&#160;have been condensed or omitted pursuant to SEC rules and regulations. The Condensed Consolidated Balance Sheet as of October&#160;30, 2021 was derived from audited financial statements, but does not include all disclosures required by GAAP. However, Ciena believes that the disclosures are adequate to understand the information presented herein. The operating results for interim periods are not necessarily indicative of the operating results for the entire year. These financial statements should be read in conjunction with Ciena&#8217;s audited consolidated financial statements and the notes thereto included in Ciena&#8217;s annual report on Form 10-K for fiscal 2021 (the &#8220;2021 Annual Report&#8221;).</span></div></ix:continuation><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%"><ix:continuation id="if118c14943a440c999f9397aec0eafe7">Ciena has a 52 or 53-week fiscal year, with quarters ending on the Saturday nearest to the last day of January, April, July and October, respectively, of each year.

Ciena continues to monitor these items and will adopt strategies to address their impact as appropriate. In certain jurisdictions, Ciena provides a valuation allowance for its deferred tax assets in excess of deferred tax liabilities because Ciena has concluded that it is more likely than not that such deferred tax assets will ultimately not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (including the reversals of deferred tax liabilities) during the periods in which those deferred tax assets will become deductible. Ciena assesses available positive and negative evidence regarding its ability to realize deferred tax assets and record a valuation allowance when it is more likely than not that deferred tax assets will not be realized. To form a conclusion, management considers its recent financial results and trends and makes judgments and estimates related to projections of profitability, the timing and extent of the use of net operating loss carryforwards, and tax planning strategies. </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:112%">Ciena will continue to evaluate future financial performance to determine whether such profitability is both sustainable and significant enough to provide sufficient evidence to support reversal of all or a portion of the valuation allowance. Any future release of valuation allowance may be recorded as a tax benefit increasing net income or as an adjustment to paid-in capital, based on tax ordering

We provide hardware, software and services that enable the transport, routing, switching, aggregation, service delivery and management of video, data and voice traffic on communications networks. Our solutions are used globally by communications service providers, cable and multiservice operators, Web-scale providers, submarine network operators, governments, enterprises, research and education institutions and emerging network operators. Our portfolio is designed to enable what we refer to as the Adaptive Network&#8482;, our vision for a network end state that emphasizes a programmable and scalable network infrastructure, software control and automation capabilities, network analytics and intelligence, and related advanced services. Our solutions include Networking Platforms, including our Converged Packet Optical and Routing and Switching portfolios, which can be applied from the network core to end-user access points, and which allow network operators to scale capacity, increase transmission speeds, allocate traffic efficiently and adapt dynamically to changing end-user service demands. To complement our Networking Platforms, we offer Platform Software, which includes a wide array of software solutions that deliver operations, administration, maintenance, and provisioning (OAM&amp;P) functionality, as well as domain control, orchestration, operational support systems (OSS) and service assurance to achieve closed loop automation across multi-vendor and multi-domain network environments.

Our quarterly order volumes during this period have significantly exceeded our  revenue and historical order volumes, with some concentration of orders among certain existing Webscale and North America-based service provider customers. We believe that we are benefiting from certain shifts in business and consumer behaviors, in part accelerated by the COVID-19 pandemic, that represent positive, long-term trends for our business. These include 5G, enterprise and consumer cloud network adoption, increasing demands on the network edge, and network operator focus on resilience and automation. We believe some portion of these orders also reflects customer acceleration of future orders due to lengthened lead times or the implementation of security of supply strategies to address the supply constraints described below. As a result, our backlog has grown from $2.2 billion at the end of fiscal 2021 to $4.4&#160;billion at the end of the third quarter of fiscal 2022. However, our order growth relative to revenue has begun to moderate from the first half of fiscal 2022 and we expect it to continue to moderate over time; and our backlog should not necessarily be viewed as an accurate indicator of revenue for any particular period. See &#8220;Risk Factors&#8221; in Item 1A of Part II of this report for further discussion of risks related to the demand environment.</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:115%">Supply Chain Constraints</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 the face of extraordinary demand across a range of industries, global supply for certain raw materials and components, including, in particular, semiconductor, integrated circuits and other electronic components used in most of our products, has experienced substantial constraint and disruption in recent periods. As a result, we have experienced significant component shortages, extended lead times, increased costs, and unexpected cancellation or delay of previously committed supply of key components across our supplier base. Beginning in the second half of fiscal 2021, we started placing significant, advanced orders for supply of certain long lead time components to address our expected customer demand for fiscal 2022 and the then emerging supply chain challenges. Since that time, we have continued to extend the duration of our purchase commitments, or placed non-cancellable, advanced orders with or through suppliers, particularly for long lead time components. As of July&#160;30, 2022 we had $2.1&#160;billion in outstanding purchase order commitments to our contract manufacturers and component suppliers for inventory. </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%">During the third quarter of fiscal 2022, reliability of supply improved and the majority of our suppliers were able to deliver components by their promised, though in many cases, extended, lead times. However, we continued to experience substantial delays and lower-than-expected component deliveries from a small group of our suppliers of integrated circuit components that represent a small fraction of our overall materials but are essential for delivering finished products. Ongoing supply constraints and the unpredictable performance of our supply chain are impacting our ability to meet customer demand and our level of revenue and growth in fiscal 2022, in particular for our Converged Packet Optical products. At the same time, increased supply chain costs, including purchase price increases, supply premiums, expediting fees and freight and logistics, have impacted our gross margin and profitability in fiscal 2022. We expect these constrained supply conditions to increase our costs of goods sold in the near term and to adversely impact our ability to continue to reduce the cost to produce our products in a manner </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%">28 </span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span><br/></span></div></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">consistent with prior periods.

We believe that this approach positions us to produce finished goods more quickly when supply constraints ease for those components for which delivery continues to be delayed. As a result of this strategy, our inventory has increased from $374.3 million at the end of fiscal 2021 to $826.7 million at the end of the third quarter of fiscal 2022. We have also implemented additional mitigation strategies, including multi-sourcing activities, qualifying alternative parts, and product redesign, and expect, over time, to realize the benefits of these mitigation activities. See &#8220;Risk Factors&#8221; in Item 1A of Part II of this report for further discussion of risks related to our supply chain and our mitigation activities.</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%">Impact of Global Events on our Business and 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:120%">COVID-19 Pandemic. </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The impact of the COVID-19 pandemic and countermeasures taken to contain its spread remain dynamic. We continue to monitor the situation and actively assess further implications for our business, supply chain, fulfillment operations and customer demand. For example, we reopened a significant number of our offices globally during fiscal 2022. We continue to take meaningful precautions in accordance with relevant guidelines to protect the health and safety of our employees. Variants continue to emerge, efforts to mitigate or contain the impacts of the pandemic continue to evolve, and the duration and severity of the impact of the pandemic on our business and results of operations in future periods remain uncertain. If the COVID-19 pandemic or its adverse effects, including the effects of government-mandated lockdowns in several cities in China during fiscal 2022, become more severe or prevalent or are prolonged in the locations where we, our customers, suppliers or manufacturers conduct business, or we experience more pronounced disruptions in our business or operations, or in economic activity and demand for our products and services generally, our business and results of operations in future periods could be materially adversely affected.

We regularly evaluate our liquidity position, debt obligations, and anticipated cash needs to fund our operating or investment plans, and will continue to consider capital raising and other market opportunities that may be available to us. We regularly evaluate alternatives to manage our capital structure and market opportunities to enhance our liquidity and provide further operational and strategic flexibility. While the COVID-19 pandemic has not materially impacted our liquidity and capital resources to date, it has led to disruptions and volatility in capital markets and credit markets. The duration and severity of any further economic or market impact of the COVID-19 pandemic remains uncertain and there can be no assurance that it will not have an adverse effect on our liquidity and capital resources, including our ability to access capital markets, in the future. </span></div><div style="margin-top:6pt"><span style="color:#000000;font-family:'Times New

We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. The inputs into certain of our judgments, assumptions, and estimates reflect, among other things, the information available to us regarding the economic implications of the COVID-19 pandemic and the armed conflict between Russia and Ukraine, and expectations as to their impacts on our business and on our critical and significant accounting estimates. Among other things, these estimates form the basis for judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions. To the extent that there are material differences between our estimates and actual results, our consolidated financial statements will be affected. In addition, because the duration, severity, and impact of the COVID-19 pandemic remain uncertain, certain of our estimates could require further judgment or modification, and therefore carry a higher degree of variability and volatility. As events continue to evolve, our estimates may change materially in future periods. </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%">Our critical accounting policies and estimates have not changed materially since&#160;October&#160;30, 2021.

This constrained supply environment has adversely affected, and could further affect, component availability, lead times and cost, and could increase the likelihood of unexpected cancellations or delays of previously committed supply of key components. During the third quarter of fiscal 2022, we continued to experience substantial delays and lower-than-expected component deliveries from a small group of our suppliers of integrated circuit components that are essential for delivering finished products. In an effort to mitigate these risks, we have incurred higher costs to secure available inventory, extended our purchase commitments and placed non-cancellable, advanced orders with or through suppliers, particularly for long lead time components. Our efforts to expand our manufacturing capacity and multi-source and pre-order components and finished goods inventory may fail to reduce the impact of these adverse supply chain conditions on our 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:115%">Despite our mitigation efforts, constrained supply conditions have and are expected to continue to adversely impact our revenue, results of operations and our ability to meet customer demand in fiscal 2022. For example, revenue for the first nine months of fiscal 2022 was adversely impacted by a range of disruptions in our supply chain, including later-than-expected deliveries, lower-than-expected component deliveries, extension of component delivery timelines into future periods, and third-party manufacturing disruptions that took production offline for periods of time. At the same time, increased costs associated with supply premiums, expediting fees and freight and logistics have impacted and can be expected to continue to adversely impact our gross margin, profitability and ability to reduce the cost to produce our products in a manner consistent with prior periods. The COVID-19 pandemic has also contributed to and exacerbated this strain, and there can be no assurance that the impacts of the pandemic on our supply chain will not continue, or worsen, in the future. The current supply chain challenges could also impact customer satisfaction or future business opportunities with customers, and result in increased use of cash, engineering design changes, and delays in new product introductions, each of which could adversely impact our business and  </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%">42 </span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span><br/></span></div></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">financial results.

Matching necessary inventory to fulfill that demand within the current supply constrained environment is challenging. We have and continue to take a number of steps to mitigate the current supply chain challenges, including extending our purchase commitments and placing non-cancellable, advanced orders with or through suppliers, particularly for long lead time components. As of July&#160;30, 2022 we had $2.1&#160;billion in outstanding purchase order commitments to our contract manufacturers and component suppliers for inventory. We have also been expanding our manufacturing capacity and have been accumulating raw materials inventory of components that are available, in some cases with expanded lead times, in an effort to prepare us to be able to produce finished goods more quickly when supply constraints ease for certain common components, including integrated circuit components, for which delivery continues to be delayed. As a result of this strategy, our inventory has increased from $374.3 million at the end of fiscal 2021 to $826.7 million at the end of the third quarter of fiscal 2022. These inventory practices further introduce obsolescence risk and are resulting in increased costs and use of cash that could adversely impact our financial results. While we have not experienced material cancellations of customer orders to date, if as a result of  increased lead times for fulfilling customer orders due to the current constrained supply environment, our customers were to cancel orders, inventory could become obsolete and we could be required to write off or write down the inventory associated with those orders. In addition, if customers were to cancel orders for which we have significant outstanding commitments to our contract manufacturers or suppliers, we may be required to purchase inventory under these commitments that we are unable to sell. 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 to meet demand and customer expectations. Our supply mitigation efforts, particularly within the current demand and supply environment, have and will continue to cause us to incur additional cost and may increase our inventory risk, each of which could adversely impact our results of operations and could result in loss of revenue, increased costs, or delays that could adversely impact customer satisfaction.</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:107%">We are experiencing unprecedented demand, and our backlog may not be an accurate indicator of our level and timing of future revenues.</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:107%">As a result of order volumes growth in recent periods, our backlog has grown from $2.2 billion at the end of fiscal 2021 to $4.4&#160;billion at the end of the third quarter of fiscal 2022. Backlog may be fulfilled several quarters following receipt of a purchase order, either due to customer purchasing schedules or due to delays caused by supply chain constraints, or in the case of certain service obligations, may relate to a multi-year support period. Our ability to fulfill backlog is being adversely impacted by the current global supply constraints described above. 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 have been rare historically. As a result, backlog should not necessarily be viewed as an accurate indicator of future revenue for any particular period. In addition, we believe that some portion of our increased order volumes in recent periods reflects customer acceleration of future orders due to the implementation of security of supply strategies, or spending that was delayed or deferred in prior years due to COVID-19 related impacts, and we do not expect this level of order volume to be sustainable in the long-term. </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:107%">We rely on third-party contract manufacturers, and our business and results of operations may be adversely affected by risks associated with their businesses, financial condition and the geographies in which they operate.</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 rely on third-party contract manufacturers, including those with facilities in Canada, Mexico, Thailand, and the United States, to perform a substantial portion of our supply chain activities, including component sourcing, manufacturing, product testing and quality, and fulfillment and logistics relating to the distribution and support of our products.

We also rely upon third-party contract manufacturers, including those with facilities in Canada, Mexico, Thailand and the United States, to manufacture, support and ship our products. Physical, regulatory, technological, market, reputational, and legal risks related to climate change in these regions and globally are increasing in impact and diversity and the magnitude of any short term or long term adverse impact on our business or results of operations remains unknown. The physical impacts of climate change, including as a result of certain types of natural disasters occurring more frequently or with more intensity or changing weather patterns, could disrupt our supply chain, result in damage to or closures of our facilities, and could otherwise have an adverse impact on our business, operating results, and financial condition. </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:112%">Our international operations are subject to complex foreign and U.S. laws and regulations, including anti-bribery and corruption laws, antitrust or competition laws, data privacy laws, such as the GDPR, and environmental regulations, among others. In particular, recent years have seen a substantial increase in anti-bribery law enforcement activity by U.S. regulators, and we currently operate and seek to operate in many parts of the world that are recognized as having greater potential for corruption. Violations of any of these laws and regulations could result in fines and penalties, criminal sanctions against us or our employees, prohibitions on the conduct of our business and on our ability to offer our products and services in certain geographies, and significant harm to our business reputation. Our policies and procedures to promote compliance with these laws and regulations and to mitigate these risks may not protect us from all acts committed by our employees or third-party vendors, including contractors, agents and services partners. Additionally, the costs of complying with these laws (including the costs of investigations, auditing and monitoring) could adversely affect our current or future business.</span></div><div style="text-indent:18pt"><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%">44 </span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span><br/></span></div></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:112%">In addition, there may be changes to our business, operations and financial results if there is instability, disruption or destruction in a significant geographic region, regardless of cause, including: war, terrorism, riot, civil insurrection or social unrest; natural or man-made disasters; or public health emergencies. For example, in February 2022, armed conflict escalated between Russia and Ukraine. The United States and certain other countries have imposed sanctions on Russia and could impose further sanctions, which could damage or disrupt international commerce and the global economy. We are complying with a broad range of U.S. and international sanctions and export control requirements imposed on Russia and, on March 7, 2022, we announced our decision to suspend our business operations in Russia immediately. Although this decision has not materially impacted our results of operations for the second or third quarters of fiscal 2022 due to the limited amount of business that we conducted in Russia historically, it is not possible to predict the broader or longer-term consequences of this conflict, which could include further sanctions, embargoes, regional instability, geopolitical shifts and adverse effects on macroeconomic conditions, security conditions, currency exchange rates and financial markets. Such geopolitical instability and uncertainty could have a negative impact on our ability to sell to, ship products to, collect payments from, and support customers in certain regions based on trade restrictions, embargoes and export control law restrictions, and logistics restrictions including closures of air space, and could increase the costs, risks and adverse impacts from supply chain and logistics challenges. </span></div><div style="text-indent:18pt"><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%">The success of our international sales and operations will depend, in large part, on our ability to anticipate and manage these risks effectively. Our failure to manage any of these risks could harm our international operations, reduce our international sales, and could give rise to liabilities, costs or other business difficulties that could adversely affect our operations and financial results. </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%">Data security breaches and cyber-attacks could compromise our intellectual property or other sensitive information and cause significant damage to our business, reputation and operational capacity.</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:112%">In the ordinary course of our business, we maintain on our network systems, and on the networks of our third-party providers, certain information that is confidential, proprietary or otherwise sensitive in nature. This information includes intellectual property, financial information and confidential business information relating to us and our customers, suppliers and other business partners. Companies in the technology industry, and in particular in the telecommunications industry, have been increasingly subjected to a wide variety of security incidents, cyber-attacks and other attempts to gain unauthorized access to networks or sensitive information. Our network systems, storage and other business applications, and the systems, storage and other business applications maintained by our third-party providers, have been in the past, and may be in the future, subjected to attempts to gain unauthorized access to our network or information, malfeasance or other system disruptions. In some cases, it is difficult to anticipate or to detect immediately such incidents and the damage caused thereby. If an actual or perceived breach of security occurs in our network or any of our third-party providers&#8217; networks, we could incur significant costs, our operations could be impacted, and our reputation could be harmed. In addition, the internet has experienced an increase in cyber threats during the COVID-19 pandemic in the form of phishing emails, malware attachments and malicious websites. These risks, as well as the number and frequency of cybersecurity events globally, may also be heightened during times of geopolitical tension or instability between countries, including, for example, the ongoing military conflict between Russia and Ukraine, from which a number of recent cybersecurity events have been alleged to have originated.</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:112%">While we work to safeguard our internal network systems and validate the security of our third-party providers to mitigate these potential risks, including through information security policies and employee awareness and training, there is no assurance that such actions will be sufficient to prevent future cyber-attacks or security breaches. We have been subjected in the past, and expect to be subjected in the future, to a range of incidents including phishing, emails purporting to come from a company executive or vendor seeking payment requests, and communications from look-alike corporate domains, as well as security-related risks created by the use of third-party software and services. While these types of incidents to which we have been subjected have not had a material effect on our business or our network security to date, future incidents involving access to or improper use of our systems, networks or products could compromise confidential or otherwise protected information, destroy or corrupt data, or otherwise disrupt our operations. These security events could also negatively impact our reputation and our competitive position and could result in litigation with third parties, regulatory action, loss of business, potential liability and increased remediation costs, any of which could have a material adverse effect on our financial condition and results of operations.</span></div><div style="margin-bottom:10pt;text-indent:18pt"><span><br/></span></div><div id="iba2a7caac6a64e079e6494e81bc3de03_169"></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%"> Item&#160;2.

The inputs into certain of Ciena&#8217;s judgments, assumptions, and estimates reflect, among other things, the information available to Ciena regarding the economic implications of the COVID-19 pandemic, and expectations as to its impact on Ciena&#8217;s business. Among other things, these estimates form the basis for judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions. To the extent that there are material differences between Ciena&#8217;s estimates and actual results, Ciena&#8217;s consolidated financial statements will be affected. In addition, because the duration and severity of COVID-19 pandemic are uncertain, certain of these estimates could require further judgment or modification and therefore carry a higher degree of variability and volatility. As events continue to evolve, Ciena&#8217;s estimates may change materially in future periods.</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%">In the opinion of management, the financial statements included in this report reflect all normal recurring adjustments that Ciena considers necessary for the fair statement of the results of operations of Ciena for the interim periods covered and of the financial position of Ciena at the date of the interim balance sheets. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with GAAP&#160;have been condensed or omitted pursuant to SEC rules and regulations. The Condensed Consolidated Balance Sheet as of October&#160;30, 2021 was derived from audited financial statements, but does not include all disclosures required by GAAP. However, Ciena believes that the disclosures are adequate to understand the information presented herein. The operating results for interim periods are not necessarily indicative of the operating results for the entire year. These financial statements should be read in conjunction with Ciena&#8217;s audited consolidated financial statements and the notes thereto included in Ciena&#8217;s annual report on Form 10-K for fiscal 2021 (the &#8220;2021 Annual Report&#8221;).</span></div>Ciena has a 52 or 53-week fiscal year, with quarters ending on the Saturday nearest to the last day of January, April, July and October, respectively, of each year.

During the third quarter of fiscal 2021, Ciena completed an internal transfer of certain of its non-U.S. intangible assets, which created amortizable tax basis resulting in the discrete recognition of a $124.2&#160;million deferred tax asset with a corresponding tax benefit. The impact of this transfer is reflected in Ciena&#8217;s effective tax rate for the quarter and nine months ended July 31, 2021, which had a significant, one-time impact on its net income for these 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-weight:400;line-height:112%">Ciena&#8217;s 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 ability to utilize tax attributes and changes in tax laws and business reorganizations. Ciena continues to monitor these items and will adopt strategies to address their impact as appropriate. In certain jurisdictions, Ciena provides a valuation allowance for its deferred tax assets in excess of deferred tax liabilities because Ciena has concluded that it is more likely than not that such deferred tax assets will ultimately not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (including the reversals of deferred tax liabilities) during the periods in which those deferred tax assets will become deductible. Ciena assesses available positive and negative evidence regarding its ability to realize deferred tax assets and record a valuation allowance when it is more likely than not that deferred tax assets will not be realized. To form a conclusion, management considers its recent financial results and trends and makes judgments and estimates related to projections of profitability, the timing and extent of the use of net operating loss carryforwards, and tax planning strategies. </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:112%">Ciena will continue to evaluate future financial performance to determine whether such profitability is both sustainable and significant enough to provide sufficient evidence to support reversal of all or a portion of the valuation allowance. Any future release of valuation allowance may be recorded as a tax benefit increasing net income or as an adjustment to paid-in capital, based on tax ordering requirements.</span></div><span></span>

that are available, in some cases with expanded lead times, in an effort to prepare Ciena to produce finished goods more quickly when supply constraints ease for certain common components, including integrated circuit components, for which delivery continues to be delayed. The increase in raw materials inventory is related to these steps to mitigate the impact of current supply chain constraints and the global market shortage of semiconductor parts. Ciena writes down its inventory for estimated obsolescence </span></div>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&#8217;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 the first nine months of fiscal 2022, Ciena recorded a provision for inventory excess and obsolescence of $12.0 million, primarily related to a decrease in the forecasted demand for certain Networking Platforms products. Deductions from the provision for excess and obsolete inventory relate primarily to the sale of previously reserved items and disposal activities.<span></span>

An operating segment may engage in business activities for which it has yet to earn revenues, for example, start-up operations may be operating segments before earning revenues.</p></div>

The inputs into certain of Ciena&#x2019;s judgments, assumptions, and estimates reflect, among other things, the information available to Ciena regarding the economic implications of the COVID-19 pandemic, and expectations as to its impact on Ciena&#x2019;s business. Among other things, these estimates form the basis for judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions. To the extent that there are material differences between Ciena&#x2019;s estimates and actual results, Ciena&#x2019;s consolidated financial statements will be affected. In addition, because the duration and severity of COVID-19 pandemic are uncertain, certain of these estimates could require further judgment or modification and therefore carry a higher degree of variability and volatility. As events continue to evolve, Ciena&#x2019;s estimates may change materially in future periods.&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 the opinion of management, the financial statements included in this report reflect all normal recurring adjustments that Ciena considers necessary for the fair statement of the results of operations of Ciena for the interim periods covered and of the financial position of Ciena at the date of the interim balance sheets. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with GAAP&#160;have been condensed or omitted pursuant to SEC rules and regulations. The Condensed Consolidated Balance Sheet as of October&#160;30, 2021 was derived from audited financial statements, but does not include all disclosures required by GAAP. However, Ciena believes that the disclosures are adequate to understand the information presented herein. The operating results for interim periods are not necessarily indicative of the operating results for the entire year. These financial statements should be read in conjunction with Ciena&#x2019;s audited consolidated financial statements and the notes thereto included in Ciena&#x2019;s annual report on Form 10-K for fiscal 2021 (the &#x201c;2021 Annual Report&#x201d;).&lt;/span&gt;&lt;/div&gt;Ciena has a 52 or 53-week fiscal year, with quarters ending on the Saturday nearest to the last day of January, April, July and October, respectively, of each year. Fiscal 2022 and 2021 are 52-week fiscal years.</us-gaap:OrganizationConsolidationAndPresentationOfFinancialStatementsDisclosureTextBlock>

During the third quarter of fiscal 2021, Ciena completed an internal transfer of certain of its non-U.S. intangible assets, which created amortizable tax basis resulting in the discrete recognition of a $124.2&#160;million deferred tax asset with a corresponding tax benefit. The impact of this transfer is reflected in Ciena&#x2019;s effective tax rate for the quarter and nine months ended July 31, 2021, which had a significant, one-time impact on its net income for these periods.&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:112%"&gt;Ciena&#x2019;s 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 ability to utilize tax attributes and changes in tax laws and business reorganizations. Ciena continues to monitor these items and will adopt strategies to address their impact as appropriate. In certain jurisdictions, Ciena provides a valuation allowance for its deferred tax assets in excess of deferred tax liabilities because Ciena has concluded that it is more likely than not that such deferred tax assets will ultimately not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (including the reversals of deferred tax liabilities) during the periods in which those deferred tax assets will become deductible. Ciena assesses available positive and negative evidence regarding its ability to realize deferred tax assets and record a valuation allowance when it is more likely than not that deferred tax assets will not be realized. To form a conclusion, management considers its recent financial results and trends and makes judgments and estimates related to projections of profitability, the timing and extent of the use of net operating loss carryforwards, and tax planning strategies. &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:112%"&gt;Ciena will continue to evaluate future financial performance to determine whether such profitability is both sustainable and significant enough to provide sufficient evidence to support reversal of all or a portion of the valuation allowance. Any future release of valuation allowance may be recorded as a tax benefit increasing net income or as an adjustment to paid-in capital, based on tax ordering requirements.&lt;/span&gt;&lt;/div&gt;</us-gaap:IncomeTaxDisclosureTextBlock>

accumulating raw materials inventory of components that are available, in some cases with expanded lead times, in an effort to prepare Ciena to produce finished goods more quickly when supply constraints ease for certain common components, including integrated circuit components, for which delivery continues to be delayed. The increase in raw materials inventory is related to these steps to mitigate the impact of current supply chain constraints and the global market shortage of semiconductor parts. Ciena writes down its inventory for estimated obsolescence &lt;/span&gt;&lt;/div&gt;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 the first nine months of fiscal 2022, Ciena recorded a provision for inventory excess and obsolescence of $12.0 million, primarily related to a decrease in the forecasted demand for certain Networking Platforms products. Deductions from the provision for excess and obsolete inventory relate primarily to the sale of previously reserved items and disposal activities.</us-gaap:InventoryDisclosureTextBlock>

The interest rate swaps fix the LIBOR rate for $350.0 million of the 2025 Term Loan (as defined in Note 16 below) at 2.957% through September 2023.

The total notional amount of forward starting swaps effective September 2023 was $350.0&#160;million as of July&#160;30, 2022.

On December 13, 2021, Ciena entered into an accelerated share repurchase agreement (the &#x201c;ASR Agreement&#x201d;) with Goldman, Sachs &amp;amp; Co.

Under the terms of the ASR Agreement, Ciena paid the Repurchase Price to Goldman, and received approximately 3.6&#160;million shares of its common stock from Goldman, calculated based on the average of the volume-weighted average prices of Ciena&#x2019;s common stock of $69.78 for the period from December 14, 2021 to February 11, 2022, less a discount, which completed the repurchases contemplated by the ASR Agreement.
