GENERAL

Overview

CIENA is a leader in the intelligent optical networking equipment market. We offer a portfolio of products for communications service providers worldwide. Our customers include long-distance carriers, competitive and incumbent local exchange carriers, Internet service providers, wireless and wholesale carriers. CIENA offers optical transport and intelligent optical switching systems that enable service providers to provision, manage and deliver high-bandwidth services to their customers. We have pursued a strategy to develop and leverage the power of disruptive technologies to change the fundamental economics of building carrier-class tele- and data-communications networks, thereby providing our customers with a competitive advantage. CIENA’s intelligent optical networking products are designed to enable carriers to deliver any time, any size, any priority bandwidth to their customers.

The Company had revenues of $1,603.2 million for its fiscal year ended October 31, 2001, an increase of more than 86% when compared with fiscal 2000 revenues of $858.8 million. The Company recorded a net loss of $1,794.1 million in fiscal 2001 compared with net income of $81.4 million for fiscal 2000. The net income for fiscal 2001 and fiscal 2000, adjusted to exclude payroll tax on stock options, settlement of accrued contract obligation, deferred compensation costs, amortization of goodwill, amortization of intangible assets, in-process research and development, restructuring costs, goodwill impairment and provision for doubtful accounts (which we refer to as “adjusted net income”) was $195.3 million and $100.9 million, respectively.

For the fiscal year ended October 31, 2001, the Company recorded revenue from sales of intelligent optical networking equipment to a total of 53 customers. This represents an increase of more than 65% over 2000’s customer base of 32. During fiscal 2001, Qwest and Sprint each represented more than 10% of CIENA’s total revenues.

CIENA believes it holds the leading position in the global next-generation optical networking market with approximately 33% market share. Our belief is based upon estimates developed from a variety of sources, including vendors’ public statements regarding their optical networking businesses, CIENA internal estimates, and recent discussions with industry analysts, such as RHK, CIR, Dell’Oro, Infonetics, KMI, and IDC.

Historically, the majority of CIENA’s revenue has come from the sale of products in a single product category: long-distance optical transport equipment. CIENA believes it is one of the worldwide market leaders in field deployment of open-architecture long-distance optical transport equipment utilizing dense wavelength division multiplexing (“DWDM”) technology. The majority of CIENA’s fiscal 2001 revenue was derived from sales of its long distance optical transport products. During the fiscal year 2001, CIENA also recognized meaningful revenue for the first time from the sale of its intelligent optical core switch, MultiWave CoreDirector. CIENA believes it holds an industry-leading market share in this important emerging product category. In addition, during 2001, CIENA also recognized revenue from the sale of its metropolitan optical transport product line, MultiWave Metro, and its next-generation multi-service access and switching platform MultiWave MetroDirector K2.

Our research and development efforts as well as potential future acquisition and partnership activities are targeted at capitalizing on our installed base of carrier customers and leveraging our position as a leader in the rapidly growing optical networking market.

INDUSTRY BACKGROUND

The world’s tele- and data-communications infrastructure is formed by fiber optic networks owned and operated by service providers. In recent years, the combination of several factors, including global deregulation which fueled competition among service providers and increased bandwidth demand resulting from the proliferation of the Internet and the emergence of electronic commerce, gave rise to the increased deployment of optical networking equipment.

Deregulation in the United States telecom industry and privatization in the international telecom industry during the 1990’s began a transition from an industry characterized by a small number of heavily regulated large service providers to one in which numerous insurgent competitors began to emerge. Rapid traffic growth and readily available capital further fueled the growth in the number of service providers as emerging carriers built networks and fought to take market share from the incumbents. This rush of capital and new competitors into the market left many service providers with a situation in which capital and operating expenses grew faster than revenues. In addition, many equipment vendors offered substantial vendor financing to service providers as a means to encourage sales, thereby creating a temporary, and ultimately unsustainable demand for networking equipment.

Toward the end of calendar 2000 and into calendar 2001, capital markets tightened, leading to what appears to be a new period of consolidation among service providers. As access to capital lessened, many service providers curtailed further network build-outs and dramatically reduced their overall capital spending. In addition, the industry saw the emergence and general availability of next generation optical networking equipment that enabled carriers to spend less and do more. This new equipment offered carriers the ability to grow their networks more efficiently while lowering both initial capital expenditures and ongoing operational expenses. The combined effect of these developments was a sharp decline in the demand for legacy telecom equipment and a general overall slowdown in carriers’ equipment purchases. As a result, many equipment vendors, who were now experiencing financial challenges of their own because of the slowdown in demand, stepped away from their previous practice of providing vendor financing. This only exacerbated the capital crunch and caused further capital spending reductions by carriers. In addition, several carriers found that they had built networks in anticipation of demand that failed to materialize and now faced an over capacity situation. Some carriers, with no access to additional capital and inadequate revenue, failed.

During this time service providers looked to new products and technologies, in particular optical networking equipment, to help them more efficiently scale their networks to handle the increased traffic load while also bringing their spending and expenses in line with their revenue growth.

CIENA’S SOLUTIONS

CIENA’s intelligent optical networking equipment was designed to enable service providers to transition from inefficient, legacy, voice-centric networks to more efficient data-optimized, intelligent optical networks. CIENA’s systems address the network scalability and capital spending challenges and the escalating operational costs faced by service providers.

	•		CIENA leverages its expertise in optics, software, systems and Application Specific Integrated Circuits (“ASICs”), to develop innovative products designed to lower the cost of constructing and operating communications networks.

	•		CIENA’s equipment can replace multiple legacy network elements with fewer, more intelligent network elements, thereby simplifying the network and lowering carriers’ initial capital costs and ongoing operations expenses.

	•		With the bandwidth flexibility and availability enabled by CIENA’s optical transport equipment utilizing DWDM technology, service providers are able to ramp their network bandwidth with demand, adding bandwidth when and where it is needed and only paying for capacity as it is added and turned up.

	•		CIENA’s equipment is designed to lower network operating costs by enabling carriers to manage network traffic and network bandwidth more efficiently.

	•		CIENA’s equipment also is designed to enable carriers to shorten the time it takes to provision services, in

			some cases from months to nearly real-time, thereby accelerating revenue generation.

	•		In addition to capital and operational cost savings, CIENA’s equipment and network management software is designed to enable carriers to offer new, revenue-generating and service-differentiating optical services.

	•		*Intelligent Optical Core Switching*. Our family of intelligent optical core switches, MultiWave CoreDirector, and MultiWave CoreDirector CI, enable carriers to manage network bandwidth more efficiently. CoreDirector and CoreDirector CI help carriers solve both the challenges of network scalability and escalating operating costs by incorporating the functionality of multiple network elements into a single network element with previously unavailable switching and bandwidth management capabilities.

	•		*Multi Service Access and Switching*. MultiWave MetroDirector K2 is CIENA’s next-generation multi-service access and switching platform designed for service providers seeking increased availability of usable, cost-effective bandwidth. MultiWave MetroDirector K2 has been designed to easily integrate into existing network environments and deliver superior levels of price/performance, bandwidth optimization, reliability, service flexibility, provisioning capabilities, and support for circuit-switched and data-centric traffic. The MultiWave MetroDirector K2 platform has an innovative architecture that helps service providers alleviate traffic gridlock in metropolitan networks, while providing the opportunity for increased revenues and improved performance from their existing network.

	•		*Optical Transport*. CIENA’s long-distance optical transport products, MultiWave CoreStream, MultiWave Sentry, MultiWave 1600, and our short distance products, MultiWave Metro, MultiWave Metro One and MultiWave Firefly, utilize DWDM technology which enables carriers to cost effectively add critical network bandwidth when and where they need it. As a result, service providers are better able to scale their networks to meet demand.

	•		*Network Management*. ON-Center, CIENA’s fully integrated family of software-based tools for comprehensive element, network and service layer management, is designed to enable accelerated deployment of new, differentiating optical services. ON-Center is designed to reduce network operating and management costs.

CIENA calls the network architecture created by these products “LightWorks.” The components of CIENA’s LightWorks architecture can be sold together as a complete network solution or separately as best-of-breed solutions. CIENA’s LightWorks architecture is designed to dramatically simplify a carrier’s network by reducing the number of network elements. We believe this network simplification will lead to lower capital equipment cost and lower operating cost.

STRATEGY

CIENA’s strategy is to maintain and build upon its market leadership in the deployment of intelligent optical networking systems and to leverage our technologies in order to provide solutions for both voice and data communications-based network architectures. We believe that the technological, operational and cost benefits of our optical networking solutions create competitive advantages for service providers worldwide. We believe our solutions will become increasingly important as these service providers are being pressed by their customers to deliver services to address the dramatic growth in Internet and other data communications traffic and at the same time need to find ways to reduce operating and capital expenses while ultimately realizing and improving profits. CIENA’s strategy includes the following:

•

Expand Our Base of Customers Using Our Optical Networking Solutions. We believe that achieving early widespread operational deployment of our systems in a particular carrier’s network will provide CIENA significant competitive advantages with respect to additional optical networking deployments and will enhance our marketing to other carriers as a field-proven supplier. While continuing to aggressively serve our existing customers, we intend to actively pursue additional optical networking deployment opportunities among carriers in domestic and foreign long distance, interoffice and local exchange markets.

•		*Target Incumbent Carriers*. The nature of our customer base requires a focused sales effort on a customer-by-customer basis. We plan to shift the focus of our sales and marketing efforts towards incumbent carriers.

•		*Sustain Our Investment in Research and Development.* We believe our future success will depend heavily on our ability to offer products that excel in meeting the needs of our customers – products that will allow them to reduce their capital expenditures and operating costs and to address the obstacles they will confront as they build out, grow and operate next generation optical networks. In order to meet this challenge, we believe we must make significant and sustained investments in enhancing our existing products and developing new ones. We must also continue to monitor developments in optical networking technology and, where appropriate, make strategic investments or acquisitions designed to help us maintain our technological leadership. We will take advantage of our strong balance sheet to continue to make investments in these areas even during periods in which our revenues are reduced by temporary declines in demand.

•		*Continue to Emphasize Technical Support and Customer Service*. CIENA markets technically advanced systems to sophisticated customers. The nature of CIENA’s systems and market require a high level of technical support and customer service. We believe we have a good reputation for our technical support and customer service and we intend to emphasize our global service, and support capabilities as differentiating factors in our efforts to maintain and enhance our market position. CIENA offers complete engineering, furnishing and installation services as well as full-time customer support from strategic locations worldwide.

•		*Maintain World Class Manufacturing Capability*. CIENA’s optical networking systems play a critical role in our customers’ networks. Quality assurance and manufacturing excellence are necessary for CIENA to achieve success. CIENA believes it has developed a world class optical manufacturing and system test capability and this capability provides CIENA with a competitive advantage. In addition, CIENA expects to utilize this expertise to leverage our manufacturing capability with contract manufacturers.

•		*Leverage the Company’s High Bandwidth Technologies and Know-How*. We believe there will be further opportunities for the application of next generation solutions in service provider networks. We believe, for instance, that the bandwidth and capacity management enabled by next generation equipment at the core of service provider networks will result in the need for more efficient traffic handling and management toward the edge of the network. CIENA expects to leverage the core competencies it has developed in the design, development and manufacturing of its optical transport and intelligent optical switching product lines by pursuing internal product development efforts, forming strategic alliances and making acquisitions to address these expected opportunities, CIENA intends to move aggressively to maintain leadership in the design and development of intelligent optical networking equipment and software that will both respond to customer needs and help customers move toward newer, higher capacity, more cost-efficient network designs for the future.

•		*Pursue the Opportunity for Solution Sales.* As one of the few equipment vendors with a complete next generation product set, CIENA is in a position to pursue a “solution sale” approach with carriers. CIENA is developing the capability to offer carriers a choice of choosing either an open architecture approach to building networks – one that potentially combines equipment from multiple vendors, or an integrated solution from CIENA – one that utilizes only CIENA equipment. With an integrated CIENA network, service providers will be able to take advantage of significant capital cost savings through the application of integrated optics across CIENA’s product lines. In addition, an integrated CIENA network will offer customers significant network management and service provisioning benefits that have the potential to lower operations costs. CIENA believes that during challenging economic times, service providers will look to consolidate the number of vendors from which they purchase. CIENA believes that its ability to offer carriers an integrated solution that delivers significant capital and operational cost savings over other vendors’ solutions will be a strategic advantage.

PRODUCTS

Our optical networking product portfolio is targeted at the critical areas of service provider networks: intelligent optical switching, long-distance optical transport, short-distance optical transport and network management.

MARKETING AND DISTRIBUTION

CIENA’s intelligent optical networking systems require substantial investment, and our target customers in the fiber optic telecommunications market — where network capacity and reliability are critical — are highly demanding and technically sophisticated. There are only a small number of such customers in any country or geographic market. Also, every network operator has unique configuration requirements, which affect the integration of optical networking systems with existing transmission equipment. The convergence of these factors leads to a very long sales cycle for optical networking equipment, often more than a year between initial introduction to the Company and commitment to purchase, and has further led CIENA to pursue sales efforts on a focused, customer-by-customer basis. See Item 7. “Management’s Discussion and Analysis of Financial Conditions and Results of Operations.”

CIENA has organized worldwide sales activities by geographical regions: North America; Latin America; Europe, Middle East, and Africa; and Asia Pacific. Sales teams, comprised of an account manager, systems engineers and technical support and training personnel, are assigned responsibility for each customer account. In some countries CIENA makes use of distributors, independent marketing representatives or independent sales consultants. CIENA has established offices in Belgium, Brazil, Canada, China, France, Germany, Japan, Korea, Mexico, Spain, Sweden, United Kingdom and United States.

In support of its worldwide selling efforts, CIENA conducts marketing communications programs intended to position and promote its products within the telecommunications industry. Marketing personnel also coordinate our participation in trade shows and conduct media relations activities with trade and general business publications.

MANUFACTURING

CIENA conducts most of the optical assembly, final assembly and final component, module and system test functions for its optical transport products at its manufacturing facilities in Maryland. It also manufactures the in-fiber Bragg gratings used in its optical transport product lines. CIENA relies on a small number of contract manufacturers to manufacture its MultiWave CoreDirector and MultiWave MetroDirector K2 product lines, with final system test and assembly performed by CIENA. We also rely on third party manufacturers to manufacture the majority of the components for our products and continue to evaluate whether additional portions of our manufacturing can be done on a reliable and cost-effective basis by third party manufacturers.

CIENA believes that portions of its manufacturing technologies and processes represent a competitive advantage. We have invested significantly in automated production capabilities, production process control systems, and manufacturing process improvements. Certain critical manufacturing functions require a highly skilled work force, and CIENA invests significant resources in training and in maintaining the quality of its manufacturing personnel.

CIENA’s optical transport product lines utilize hundreds of individual parts, many of which are customized for us. Component suppliers in the specialized, high technology end of the optical communications industry are generally not as plentiful or, in some cases, as reliable, as component suppliers, in more mature industries. CIENA works closely with its strategic component suppliers to pursue new component technologies that could either reduce cost or enhance the performance of our products.

COMPETITION

Competition in the telecommunications equipment industry is intense, particularly in that portion of the industry focused on delivering higher bandwidth and more cost effective services throughout the telecommunications network. CIENA believes that its position as a leading supplier of open architecture optical networking equipment gives it a competitive advantage and expects to leverage that advantage by gaining general market acceptance of its core and access switching products. However, competition has been and will continue to be very intense. See Item 7. “Management’s Discussion and Analysis of Financial Conditions and Results of Operations.”

CIENA’s competition is dominated by a small number of very large, usually multinational, vertically integrated companies, each of which has substantially greater financial, technical and marketing resources, and greater manufacturing capacity as well as better established relationships with the incumbent carriers than CIENA. Included among CIENA’s competitors are Lucent Technologies Inc., (“Lucent”), Northern Telecom Inc. (“Nortel”), Alcatel Alsthom Group (“Alcatel”), NEC Corporation (“NEC”), Cisco Systems, Inc. (“Cisco”), Siemens AG (“Siemens”), Fujitsu Group (“Fujitsu”), Hitachi Ltd. (“Hitachi”) and Telefon AB LM Ericsson (“Ericsson”). CIENA also believes that several smaller companies, such as ONI Systems Corp. (“ONI”), Sycamore Networks, Inc. (“Sycamore”), Corvis Corporation (“Corvis”), and Tellium, Inc. (“Tellium”), will be able to win some share of the optical networking market. CIENA believes each of its major competitors is engaged in the development, introduction or deployment of products directly competitive with CIENA’s optical transport, core switching and next-generation multi-service access and switching platforms.

In addition to optical networking equipment suppliers, traditional TDM-based transmission, SONET multiplexing, and digital cross-connect equipment suppliers compete with CIENA in the market for transmission capacity and switching capabilities. Lucent, Alcatel, Tellabs, Inc. (“Tellabs”), Nortel, Fujitsu, Hitachi and NEC are already providers of a full complement of such transmission and switching equipment. These and other competitors have introduced or are expected to introduce equipment that will offer 10 Gbps transmission and/or switching capability.

Patents and Other Intellectual Property Rights

CIENA has licensed intellectual property from third parties, including certain key enabling technologies with respect to the production of in-fiber Bragg gratings; utilized publicly available technology associated with Erbium-doped fiber amplifiers; and applied its design, engineering and manufacturing skills to develop its optical transport systems. These licenses expire when the last of the licensed patents expires or is abandoned. CIENA also licenses from third parties certain software components for its network management products. These licenses are perpetual but will generally terminate after an uncured breach of the agreement by CIENA. CIENA also relies on contractual rights, trade secrets and copyrights to establish and protect its proprietary rights in its products.

CIENA enforces its intellectual property rights vigorously against infringement or misappropriation. CIENA’s practice is to require its employees and consultants to execute non-disclosure and proprietary rights agreements upon commencement of employment or consulting arrangements with CIENA. These agreements acknowledge CIENA’s exclusive ownership of all intellectual property developed by the individual during the course of his or her work with CIENA, and require that all proprietary information disclosed to the individual will remain confidential. CIENA’s employees generally also sign agreements not to compete with CIENA for a period of twelve months following any termination of employment.

As of November 2001, CIENA had received 81 United States patents, and 213 pending U.S. patent applications. We also have a number of foreign patents and patent applications. Of the United States patents that have been issued to CIENA, the earliest any will expire is 2015. Pursuant to an agreement between CIENA and General Instrument Corporation dated March 10, 1997, CIENA is a co-owner with General Instrument Corporation of a portfolio of 27 United States and foreign patents relating to optical communications, primarily for video-on-demand applications. See Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

EMPLOYEES

As of October 31, 2001, CIENA and its subsidiaries employed 3,778 persons, of whom 962 were primarily engaged in research and development activities, 1,624 in manufacturing, 275 in installation services, 578 in sales, marketing, customer support and related activities and 339 in administration. On November 12, 2001, CIENA announced a reduction in its manufacturing and manufacturing support workforce of approximately 10 percent or approximately 380 employees. None of CIENA’s employees are currently represented by a labor union. CIENA considers its relations with its employees to be good.

COMPANY

CIENA Corporation was incorporated in Delaware in November 1992. We completed our initial public offering on February 7, 1997, a secondary offering on July 2, 1997, and a follow-on offering on February 9, 2001. CIENA’s principal executive offices are located at 1201 Winterson Road, Linthicum, Maryland 21090. Our telephone number is (410) 865-8500.

Item 2. Properties

As of October 31, 2001, all of CIENA’s properties are leased. CIENA’s principal executive offices are located in Linthicum, Maryland. We lease space at 14 buildings located at various sites near Linthicum, Maryland, two as engineering facilities, nine as manufacturing facilities, two as sales facilities and one as an administrative facility. The company has engineering and or manufacturing facilities located in Marlborough, Massachusetts; Alpharetta, Georgia; Cupertino, California; and Fremont, California.

The company also leases various small offices in the United States and abroad to support its sales and installation services. For additional information regarding the Company’s lease obligations. See Item 8. “Financial Statements and Supplementary Data”

We recorded a restructuring charge of $15.4 million relating to consolidation of excess facilities during fiscal 2001. The consolidation included the closure of certain manufacturing warehouse facilities and the consolidation of certain operational centers related to business activities that have been restructured. The charge included $7.0 million primarily related to lease terminations and non-cancelable lease costs and also included $8.4 million write-down related to property and equipment consisting primarily of leasehold improvements and production equipment.

Item 3. Legal Proceedings

On July 19, 2000, CIENA and CIENA Properties, Inc., a wholly owned subsidiary of CIENA, filed a complaint in the United States District Court for the District of Delaware requesting damages and injunctive relief against Corvis Corporation. The complaint charges Corvis Corporation with infringing several patents relating to CIENA’s optical networking communication systems and technology. On September 8, 2000, Corvis filed an Answer and Counterclaim alleging invalidity, non-infringement and unenforceability of the asserted patents, and tortious interference with prospective economic advantage. CIENA believes that Corvis’ counterclaims are without merit, and intends to defend itself vigorously. The suit is still in discovery proceedings. The trial of the matter is scheduled to begin on April 1, 2002. On the basis of the proceedings so far, we continue to believe we have a strong case on both our own claim and the counterclaim. Litigation is inherently uncertain, however, and there remains a possibility that we could lose either or both.

On October 3, 2000, Stanford University and Litton Systems filed a complaint in U.S. District Court for the Central District of California alleging that optical fiber amplifiers incorporated into CIENA’s products infringe U.S. Patent No. 4,859,016. We are unable to estimate what impact, if any, an adverse outcome would have on the Company. To date, we have not been served with a complaint in the proceeding. If served, we intend to defend the action vigorously.

Item 4. Submission of Matters to a Vote of Security Holders

No matters were submitted to a vote of security holders during the fourth quarter of fiscal 2001.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with “Selected Consolidated Financial Data” and the Company’s consolidated financial statements and notes thereto included elsewhere in this report on Form 10-K.

Overview

CIENA’s LightWorks architecture is an optical networking architecture designed to reduce both the capital and the operating costs of building service provider networks. The LightWorks architecture addresses the critical areas of optical networking: long-distance optical transport, short-distance optical transport, intelligent optical switching, and network management. It allows us to combine the functionalities that previously required several network elements into a single element, thereby lowering the customer’s capital equipment requirements and simplifying its network so as to reduce operating costs.

The products included in CIENA’s LightWorks architecture can be sold together as a complete network solution or separately as best-of-breed solutions. Products include four generations of long distance optical transport systems: MultiWave 1600, MultiWave Sentry 1600, MultiWave Sentry 4000, and MultiWave CoreStream. LightWorks also includes CIENA’s short distance optical transport products: MultiWave Firefly, MultiWave Metro, and MultiWave Metro One. CIENA’s LightWorks architecture also includes its MultiWave CoreDirector family of optical core switching products: MultiWave CoreDirector and MultiWave CoreDirector CI. Our Lightworks architecture also includes MultiWave MetroDirector K2. The recently introduced MultiWave MetroDirector K2 is a next generation multi-service access and switching platform designed to help carriers alleviate metro area gridlock, while providing the opportunity for increased revenue and performance from their existing networks.

On February 9, 2001, we completed a public offering of 11,000,000 shares of common stock at a price of $83.50 per share less underwriters’ discounts and commissions. Concurrent with this offering we also completed a public offering of 3.75% convertible notes with an aggregate principal amount of $690 million. The aggregate net proceeds from these offerings were approximately $1.6 billion, after deducting underwriting discounts, commissions and offering expenses. Pending our use of the net proceeds, we have invested them in interest bearing, investment grade securities.

On March 29, 2001, CIENA acquired all of the outstanding capital stock, and assumed the options of Cyras Systems, Inc. (“Cyras”), a privately held provider of next-generation optical networking systems based in Fremont, California. The purchase price was approximately $2.2 billion and consisted of the issuance of approximately 26.1 million shares of CIENA common stock, the assumption of approximately 1.9 million stock options and the indirect assumption of $150 million principal amount of Cyras’s convertible subordinated indebtedness. The Cyras K2 product, which has become CIENA’s MultiWave MetroDirector K2, became available for shipment in the third quarter of fiscal 2001.

As part of our review of financial results for 2001, we performed an assessment of the carrying value of our long-lived assets including significant amounts of goodwill and other intangible assets recorded in connection with the acquisition of Cyras. Pursuant to Statement Financial Accounting Standards No. 121 “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of” (SFAS 121) the assessment was performed because of the significant negative industry and economic trends affecting both the Company’s current operations and expected future sales of MultiWave MetroDirector K2 as well as the general decline of technology valuations. It was concluded that the decline in market conditions within the Company’s industry was significant and other than temporary. As a result, the Company recorded a charge of $1.7 billion to reduce goodwill during the fourth quarter of 2001 based on the amount by which the carrying amount of these assets exceeded their estimated fair value. The write down is related to the goodwill associated with the Cyras transaction.

In the fourth quarter of fiscal 2001, we also recorded a restructuring charge of $15.4 million related to the consolidation of excess facilities. The consolidation included the closure of certain manufacturing warehouse facilities and the consolidation of certain operational centers related to business activities that have been restructured. The restructuring charge had two primary components. The first component was $7 million related lease terminations and non-cancelable lease costs. This amount is included in the Company’s accrued liabilities at October 31, 2001. As of October 31, 2001, none of these exit costs have been paid; the Company expects to pay these costs over the remaining lease terms. There have been no adjustments to the lease liability. The second component of the restructuring was a write-down to fair value of leasehold improvements and fixed assets associated with the leases being consolidated. The company determined the fair value of these assets based on current market conditions and recent sales activity from this type of asset. The write-down of these assets is classified in the restructuring charges on the statement of operations.

As of October 31, 2001, the Company and its subsidiaries employed approximately 3,778 persons, which was an increase of 1,003 persons over the approximate 2,775 employed on October 31, 2000. On November 12, 2001, we announced a workforce reduction of approximately 380 employees concentrated in manufacturing operations staff. Affected employees will be paid through January 10, 2002 and will be eligible for additional severance packages. They also received outplacement assistance and training. CIENA will record a restructuring charge of between $5 million and $6 million associated with this action, in the first quarter of fiscal 2002.

For much of the last five years the market for our equipment has been influenced by the entry into the communications services business of a substantial number of new companies. In the United States this was due largely to changes in the regulatory environment, in particular those brought about by the Telecommunications Act of 1996. These new companies raised billions of dollars in capital, much of which they invested in new plant, causing an acceleration in the growth of the market for telecommunications equipment.

The last year or so has seen a reversal of this trend, including the failure of a large number of the new entrants and a sharp contraction of the availability of capital to the industry. This, in turn, has caused a substantial reduction in demand for telecommunications equipment, including our products.

This industry trend has been compounded by the slowing not only of the United States economy – which is now in recession – but the economies in virtually all of the countries in which we are marketing our products. Moreover, the economic uncertainty has been accentuated by the events of September 11, 2001. The combination of these factors has caused most of our customers to become more conservative in their capital investment plans and more uncertain about their future purchases. As a consequence, we are facing a market that is, both reduced in absolute size and more difficult to predict and plan for.

Results of Operations

Fiscal Years Ended 2001, 2000 and 1999

Revenue. We recognized $1,603.2 million, $858.8 million and $482.1 million in revenue for the fiscal years ended October 31, 2001, 2000, and 1999, respectively. The increase in revenue of approximately $744.4 million, or 86.7% from fiscal 2000 to 2001 was due primarily to an increase in shipments of both long distance optical transport products, primarily configured for 10.0 Gbps transmission rates, and intelligent core switching products. The increase in revenue of approximately $376.7 million, or 78.1%, from fiscal 1999 to fiscal 2000 was due primarily to an increase in shipments across all product lines.

CIENA recognized revenues from a total of 53, 32 and 27 optical equipment customers during fiscal 2001, 2000, and 1999, respectively. During fiscal 2001, Sprint and Qwest Communications each accounted for at least 10% of our revenue and together they accounted for 50.5% of total revenue. During fiscal 2000, Sprint, Qwest Communications and GTS Network Ltd. each accounted for at least 10% of our revenue and combined they accounted for 60.9% of total revenue. During fiscal 1999 Sprint, WorldCom, and GTS Network Ltd., each accounted for at least 10% of our revenue and combined they accounted for 46.2% of total revenue. Revenue from overseas sales accounted for approximately 23.9%, 33.0% and 44.3%, of our total revenue during fiscal 2001, 2000 and 1999 respectively.

For the reasons discussed above in the overview, we anticipate our revenue for first quarter of fiscal 2002, will be less, and possibly significantly less than our revenues in the 4th fiscal quarter 2001. Given the current uncertainty in the market we have limited visibility of our revenues for fiscal 2002. See “Risk Factors.”

Gross Profit. Cost of goods sold consists of component costs, direct compensation costs, warranty and other contractual obligations, royalties, license fees, inventory obsolescence costs and overhead related to the Company’s manufacturing and engineering, furnishing and installation operations. Gross profit was $698.7 million, $381.4 million and $182.3 million for fiscal 2001, 2000, and 1999, respectively. Gross margin was 43.6%, 44.4% and 37.8% for fiscal 2001, 2000 and 1999, respectively. The decrease in gross margin from fiscal 2000 to fiscal 2001 was due primarily to an increase in inventory obsolescence costs and price reductions resulting from competitive pressures, which were partially offset by increased sales of higher margin products such as MultiWave CoreDirector systems and LightWorks On-Center network element and service management software. The increase in gross margin from fiscal 1999 to fiscal 2000 was due primarily to lower component costs and improved production efficiencies.

As discussed above, our current ability to make reliable forecasts for fiscal 2002 is limited. It is possible, however, that we could experience reductions of gross margins compared to fiscal 2001 as a result of one or more of several factors, including changes in product mix, downward pressure on pricing due to more aggressive competition, decreased manufacturing efficiencies, increases in inventory obsolescence, and increased costs of components.

Research and Development Expenses. Research and development expenses were $235.8 million, $125.4 million and $101.0 million for fiscal 2001, 2000 and 1999, respectively. The approximate $110.4 million, or 88.0% increase from fiscal 2000 to 2001 was related to increases in staffing, prototype parts and depreciation expenses. The approximate $24.4 million, or 24.2% increase from fiscal 1999 to 2000 in research and development expenses related to increased staffing levels, purchases of materials used in development of new or enhanced product prototypes, and outside consulting services in support of certain developments and design efforts. During fiscal 2001, 2000 and 1999, research and development expenses were 14.7% 14.6% and 21.0% of revenue, respectively. CIENA expects that its research and development expenditures will continue to increase in absolute dollars and as a percentage of revenue during fiscal 2002 to support the continued development of CIENA’s intelligent optical networking products, the exploration of new or complementary technologies, and the pursuit of various cost reduction strategies. CIENA has expensed research and development costs as incurred.

Selling and Marketing Expenses. Selling and marketing expenses were $146.9 million, $90.9 million and $61.6 million for fiscal 2001, 2000 and 1999, respectively. The approximate $56.0 million or 61.6% increase from fiscal 2000 to 2001 and the approximate $29.3 million or 47.6% increase from fiscal 1999 to 2000 in selling and marketing expenses were primarily the result of increases in staffing levels, commissions earned, depreciation expenses, trade show participation and promotional costs. During fiscal 2001, 2000 and 1999 selling and marketing expenses were 9.2%, 10.6% and 12.8% of revenue, respectively. The Company anticipates that its selling and marketing expenses will increase in absolute dollars and as a percentage of revenue during fiscal 2002 as additional personnel are hired and additional offices are opened to pursue new customers and market opportunities. The Company also expects the portion of selling and marketing expenses attributable to technical assistance and field support, specifically in Europe, Latin America, and Asia, will increase as the Company’s installed base of operational MultiWave systems increases.

General and Administrative Expenses. General and administrative expenses were $57.9 million, $34.0 million and $22.7 million for fiscal 2001, 2000 and 1999, respectively. The approximate $23.9 million or 70.4% increase from fiscal 2000 to 2001 and the $11.2 million or 49.5% increase from fiscal year 1999 to 2000 were primarily the result of increased staffing levels and outside consulting services. During fiscal 2001, 2000 and 1999 general and administrative expenses were 3.6%, 4.0% and 4.7% of revenue, respectively. The Company believes that its general and administrative expenses will increase in absolute dollars and as a percentage of revenue during fiscal 2002 as a result of the expansion of the Company’s administrative staff required to support its expanding operations.

Settlement of Accrued Contract Obligation. The $8.5 million gain from settlement of accrued contract obligation recorded in fiscal 2000 relates to the July 2000 termination of certain accrued contract obligations that CIENA received from iaxis Limited, one of CIENA’s European customers. In September 2000, CIENA was informed that an administrative order had been issued by a London court against iaxis Limited. As a result of this order, joint administrators were appointed to manage the business of iaxis Limited while they marketed the business for sale and formulated a reorganization of the company. See “Provision for Doubtful Accounts” below.

Deferred Stock Compensation Costs. Deferred stock compensation costs were $41.4 million during fiscal 2001. As part of our acquisition of Cyras, we recorded $98.5 million of deferred stock compensation relating to the unvested stock options and restricted stock assumed in the acquisition. Deferred stock compensation is presented as a reduction of stockholders’ equity and is amortized over the remaining vesting period of the applicable options.

Amortization of Goodwill. Amortization of goodwill costs were $177.8 million, $3.2 million and $3.2 million for fiscal 2001, 2000 and 1999, respectively. The approximate $174.6 million increase in amortization of goodwill from fiscal 2000 to 2001 was related to CIENA’s acquisition of Cyras, which was accounted for under the purchase method of accounting. We recorded goodwill and workforce related intangibles of approximately $2.1 billion representing the excess of the purchase price paid over the fair value of the net tangible and other intangible assets acquired. The goodwill and workforce acquired from the Cyras purchase was amortized using a straight-line method based upon a three to seven-year period during fiscal 2001. As a result of the issuance of SFAS No. 142, we will not record amortization in subsequent fiscal years. See “Goodwill Impairment” below.

Amortization of Intangible Assets. Amortization of intangible assets was $4.4 million, $0.4 million and $0.4 million for fiscal 2001, 2000 and 1999, respectively. The approximate $4.0 million, or 907.5% increase in amortization from 2000 to 2001 is related to our acquisition of Cyras, for which we recorded $47.7 million worth of other intangible assets. The other intangible assets from the Cyras purchase will be amortized over a seven-year period. See “Goodwill Impairment” below.

In-Process Research and Development. In connection with the Cyras acquisition, we recorded a $45.9 million charge for in-process research and development during fiscal 2001. This represents the estimated value of purchased in-process technology related to Cyras’s K2 product development that had not yet reached technological feasibility and had no alternative future use at the time of the acquisition. The amount of purchase price allocated to in-process research and development was determined using the discounted cash flow method. This method consisted of estimating future net cash flows attributable to the in-process K2 technology for a discrete projection period and discounting the net cash flows back to their present value.

Restructuring Costs. We recorded a restructuring charge of $15.4 million relating to consolidation of excess facilities during fiscal 2001. The consolidation included the closure of certain manufacturing warehouse facilities and the consolidation of certain operational centers related to business activities that have been restructured. The charge included $7.0 million primarily related to lease terminations and non-cancelable lease costs and also included an $8.4 million write-down related to property and equipment consisting primarily of leasehold improvements and production equipment.

Goodwill Impairment. As part of our review of financial results for fiscal 2001, we performed an assessment of the carrying value of our long-lived assets including significant amounts of goodwill and other intangible assets recorded in connection with the acquisition of Cyras. The assessment was performed pursuant to Statement Financial Accounting Standards No. 121 “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of” (SFAS 121) because of the significant negative industry and economic trends affecting both the Company’s current operations and expected future sales of MultiWave MetroDirector K2 as well as the general decline of technology valuations. The conclusion of that assessment was that the decline in market conditions within the Company’s industry was significant and other than temporary. As a result, the Company recorded a charge of $1.7 billion to reduce goodwill during the fourth quarter of 2001 based on the amount by which the carrying amount of these assets exceeded their fair value. The write down is related to the goodwill associated with the Cyras transaction. Fair value was determined based on discounted future cash flows for the operating entity, which had separately identifiable cash flows. The cash flow periods used were six years, applying annual growth rates ranging from 25% to 100%. The discount rate used was 11.3%, and the terminal values were estimated based upon a terminal growth rates of 4%. The assumptions supporting the estimated future cash flows, including the discount rate and estimated terminal values, reflect management’s best estimates. The discount rate was based upon the Company’s weighted average cost of capital as adjusted for the risks associated with its operations.

Merger Related Costs. The merger costs for fiscal 1999 of approximately $13.0 million were related to CIENA’s acquisition of Omnia and Lightera. These costs include an $8.1 million non-cash charge for the acceleration of warrants based upon CIENA’s common stock price on June 30, 1999 and $4.9 million for fees, legal and accounting services and other costs. The warrants were issued to one of Omnia’s potential customers and became exercisable upon the consummation of the merger between CIENA and Omnia.

Provision for Doubtful Accounts. CIENA performs ongoing credit evaluations of its customers and generally does not require collateral from its customers. CIENA maintains an allowance for potential losses when identified. CIENA’s allowance for doubtful accounts as of October 31, 2001 and October 31, 2000 was $1.5 million and $29.6 million, respectively. Approximately $27.8 million of the October 31, 2000 balance relates to provisions made for doubtful accounts associated with iaxis Limited, one of CIENA’s European customers. In September 2000, CIENA was informed that an administrative order had been issued by a London court against iaxis Limited. As a result of this order, joint administrators were appointed to manage the business of iaxis Limited while they marketed the business for sale and formulated a reorganization of the company. In November 2000, CIENA was notified that Dynegy Inc. had entered into a proposed agreement to acquire the assets and stock of iaxis Limited from the administrators. As a consequence of the terms of (a) the proposed agreement between the administrators of iaxis Limited and Dynegy, and of (b) a related sales agreement between CIENA and Dynegy, CIENA expected to realize approximately $8.9 million of the gross outstanding accounts receivable balance due from iaxis Limited as of October 31, 2000. In July 2001 CIENA received approximately $15.4 million of the gross outstanding accounts receivable balance due from iaxis Limited primarily through the sales agreement with Dynegy. Accordingly, CIENA recognized a reduction in the provision for doubtful accounts of $6.6 million during fiscal 2001.

Other Income (Expense), Net. Other income (expense), net, consists of interest income earned on the Company’s cash, cash equivalents and available-for-sale securities, net of interest expense associated with the Company’s debt obligations. Other income (expense), net, was $33.0 million, $12.7 million and $13.9 million for fiscal 2001, 2000 and 1999, respectively. The increase in other income (expense) from fiscal 2000 to 2001 was due to increases in cash, cash equivalents and available-for-sale securities offset by increased interest expense. The decrease in other income (expense) from fiscal 1999 to fiscal 2000 was due to lower balances of cash, cash equivalents and short-term investments in fiscal 2000 as compared to fiscal 1999.

Provision (Benefit) For Income Taxes. CIENA’s provision (benefit) for income taxes was (5.1)%, 32.5% and (34.5%) of pre-tax earnings (loss) for fiscal 2001, 2000 and 1999, respectively. The income tax provision for 2001 was $87.3 million. The income tax provision for 2001 was higher than the expected 35% benefit due to the non-deductibility of the goodwill impairment, and in-process research and development. The income tax provision for 2000 was lower than the expected 35% primarily due to benefits from research and development tax credits. The benefit for fiscal 1999 was less than the expected statutory benefit of 35% due to non-deductible merger costs. As of October 31, 2001, CIENA’s deferred tax asset was $186.9 million. The realization of this asset could be adversely affected if future earnings are lower than anticipated.

Liquidity and Capital Resources

At October 31, 2001, CIENA’s principal source of liquidity was its cash and cash equivalents, and short-term and long-term investments. The Company had $397.9 million in cash and cash equivalents, and $1,397.3 million short-term and long-term investments.

The Company’s operating activities provided cash of $157.0 million, $59.0 million and $28.7 million for fiscal 2001, 2000 and 1999, respectively. Cash provided by operations in fiscal 2001 was primarily attributable to a net loss adjusted for the non-cash charges of amortization of goodwill, other intangibles, deferred stock compensation and debt issuance costs, depreciation, in-process research and development, tax benefit related to exercise of stock options, inventory obsolescence, and warranty, increases in accounts payable and accruals, and deferred revenue and other obligations, offset by increases in accounts receivable, inventories and prepaid expenses.

Cash used in investment activities in fiscal 2001, 2000 and 1999 was $1,490.6 million, $103.2 million and $149.7 million, respectively. Investment activities included the net redemption of $23.8 million of short and long-term investments during 2000 and the net purchase of $103.0 million and $1,293.2 million of short and long-term investments during 1999 and 2001, respectively. Investment activities also include approximately $3.0 million and $13.0 million of equity investments in private companies during fiscal 2000 and 2001, respectively. Also included in investment activities were additions to capital equipment and leasehold improvements in fiscal 2001, 2000 and 1999 of $238.5 million, $123.9 million and $46.8 million, respectively. The capital equipment expenditures were primarily for test, manufacturing and computer equipment. The Company expects additional combined capital equipment and leasehold improvement expenditures of approximately $90.0 million to be made during fiscal 2002 to support selling and marketing, manufacturing and product development activities and the construction of leasehold improvements for its facilities, and we will use our cash and cash equivalents to fund these purchases.

We generated $1,588.4 million, $43.9 million and $13.8 million in cash from financing activities in fiscal 2001, 2000 and 1999, respectively. During fiscal 2001, CIENA received $31.9 million from the exercise of stock options and the sale of stock through our employee stock purchase plan. On February 9, 2001, we completed a public offering of 11,000,000 shares of common stock at a price of $83.50 per share less underwriters’ discounts and commissions. Concurrent with the offering of common stock, we completed a public offering of 3.75% convertible notes with an aggregate principal amount of $690 million. Net proceeds from these offerings were approximately $1,547.8 million, after deducting underwriting discounts, commissions and offering. During fiscal 2000, CIENA received $44.0 million from the exercise of stock options and the sale of stock through our employee stock purchase plan. During fiscal 1999, CIENA received $11.3 million from the exercise of stock options, the sale of stock through our employee stock purchase plan, and from the additional capitalization of Omnia and Lightera.

Cyras Systems LLC, our wholly owned subsidiary, has $150 million of 4.5% convertible subordinated notes outstanding. In the event that the holders of the Cyras notes convert their notes into our common stock, we would have to issue a significant number of shares of additional common stock. Based on the exchange ratio for the Cyras acquisition of approximately 0.13, we will have to issue approximately 1,037,055 shares of our common stock if holders of the entire $150 million of convertible notes decided to convert their notes. At our current stock price it appears more likely that the holders of the Cyras notes will not elect to convert them into our common stock before March 31, 2002. As a result, it is probable that we will have to make an offer to repurchase the notes at 118.942% of their principal balance on April 30, 2002. If all of the note holders accept that offer, we will have to expend approximately $178 million of our cash and cash equivalents for the repurchase.

We believe that our existing cash balances and investments, together with cash flow from operations, will be sufficient to meet our liquidity and capital spending requirements at least through the end of fiscal 2002. However, investments in or acquisitions of complementary businesses, products or technologies may require us to seek additional financing prior to that time. We cannot be certain that additional debt or equity financing will be available when required or, if available, that we can secure it on terms satisfactory to us.

Effects of Recent Accounting Pronouncements

combinations, and prohibits the pooling-of-interests method of accounting. This statement is effective for all business combinations initiated after June 30, 2001 and supercedes APB Opinion No. 16, “Business Combinations” as well as Financial Accounting Standards Board Statement of Financial Accounting Standards No. 38, “Accounting for Preacquisition Contingencies of Purchased Enterprises”.

SFAS No. 142 addresses how intangible assets that are acquired individually or with a group of other assets should be accounted for in financial statements upon their acquisition. This statement requires goodwill amortization to cease and for goodwill to be periodically reviewed for impairment, for fiscal years beginning after October 31, 2001. SFAS No. 142 supercedes APB Opinion No. 17, “Intangible Assets”. The company will adopt the provisions of this standard for its first quarter of fiscal 2002. The Company has recorded goodwill amortization expense of $3.2 million, $3.2 million, and $177.8 million for fiscal years 1999, 2000 and 2001, respectively, and will no longer be recorded in subsequent fiscal year.

In August 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standard No. 143, “Accounting for Asset Retirement Obligation” (SFAS No. 143). SFAS No. 143 is effective for fiscal years beginning after June 15, 2002, and will require companies to record a liability for asset retirement obligations in the period in which they are incurred, which typically could be upon completion or shortly thereafter. The FASB decided to limit the scope to legal obligation and the liability will be recorded at fair value. The effect of adoption of this standard on our results of operations and financial positions is being evaluated.

In October 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standard No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (SFAS No. 144). SFAS No. 144 is effective for fiscal years beginning after December 15, 2001. It provides a single accounting model for long-lived assets to be disposed of and replaces SFAS No. 121 “Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of.” The effect of adoption of this standard on our results of operations and financial positions is being evaluated.

CIENA’s quarterly operating results have varied, and we expect them to vary in the future. The detailed discussion of risk factors below addresses the principal factors that have caused these variations in the past, and may cause similar variations in the future. See “Risk Factors”.

CIENA’s revenues increased during each of the seven quarters beginning in the first quarter of fiscal 2000 through the third quarter of fiscal 2001 due to a strong demand across existing products and introduction of new products such as MultiWave CoreStream long-distance optical transport systems configured for both 2.5 Gbps and 10.0 Gbps transmission rates, and our intelligent optical core switching product the MultiWave CoreDirector. The decline in revenues during the fourth quarter of fiscal 2001 compared to the third quarter of fiscal 2001 was primarily the result of a reduction in sales of our long-distance optical transport systems partially offset by a continued increase in sales of our intelligent optical switching and multi-service access products, the MultiWave CoreDirector and MultiWave MetroDirector K2.

CIENA’s gross margin percentage improved from the first quarter fiscal 2000 to the second quarter fiscal 2001 as a result of component cost reductions, production efficiencies, favorable product mix and relative stable sales pricing. The decline in gross margins in the third quarter of fiscal 2001 was primarily the result of increased inventory obsolescence costs due to the sudden decrease in demand for our older generation long-distance optical transport products. The further decline in gross margin during the fourth quarter of fiscal 2001 was primarily the result of increased production inefficiencies and costs due to lower demand requirements. CIENA’s operating expenses have increased in each of the last eight quarters due to continued investments in research and development, selling and marketing, and infrastructure activities. During fiscal 2002, CIENA’s operating expenses will continue to increase in absolute dollars and as percentage of revenue. We expect to preserve and enhance our market leadership and build on our installed base with new and additional products in conjunction with increased investments in selling, marketing, and customer service activities. See “Risk Factors”.

RISK FACTORS

Investing in our securities involves a high degree of risk. In addition to the other information contained in this annual report, including the reports we incorporate by reference, you should consider the following factors before investing in our securities.

Our Business Has Been Adversely Affected by Recent Developments in the Communications Industry and the Economy in General

For much of the last five years the market for our equipment has been influenced by the entry into the communications services business of a substantial number of new companies. In the United States this was due largely to changes in the regulatory environment, in particular those brought about by the Telecommunications Act of 1996. These new companies raised billions of dollars in capital, much of which they invested in new plants, causing an acceleration in the growth of the market for telecommunications equipment.

We expect the factors described above to affect our business, for at least several quarters if not longer, in several significant ways compared to the recent past:

	•		it is likely that our markets will be characterized by reduced capital expenditures by our customers;

	•		our ability to forecast the volume and product mix of our sales will be substantially reduced;

	•		managing our expenditures will be significantly more difficult in light of the uncertainties surrounding in our business;

	•		increased competition resulting from reduced demand will put substantial downward pressures on the pricing of our products, tending to reduce our profit margins;

	•		increased competition has also enabled customers to insist on more favorable terms and conditions for sales, including extended payment terms or other financing assistance, as a condition of procuring their business; and

	•		the result in any or combination of these factors could be reduced revenues and profitability and perhaps losses in particular periods or for the entire year.

Our Results Can Fluctuate Unpredictably

In general, our revenues and operating results in any reporting period may fluctuate significantly due to a variety of factors including:

	•		fluctuations in demand for our products;

	•		changes in our pricing policies or the pricing policies of our competitors;

	•		the timing and size of orders from customers;

	•		changes in customers’ requirements, including changes or cancellations to orders from customers;

	•		the introduction of new products by us or our competitors;

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

	•		readiness of customer sites for installation;

	•		satisfaction of contractual customer acceptance criteria and related revenue recognition issues;

	•		manufacturing and shipment delays and deferrals;

	•		increased service, installation, warranty or repair costs;

	•		the timing and amount of employer payroll tax to be paid on employee gains on stock options exercised; and

	•		changes in general economic conditions as well as those specific to the telecommunications and intelligent optical networking industries.

Our intelligent optical networking products require large investments. We have only a limited number of potential customers in each geographic market, and each has unique needs. Our customers are generally technically sophisticated and demanding. As a result, the sales cycles for our products are long, often as much as a year or two between initial contact with a potential customer and the recognition of revenue from sales to the customer. Our customers’ purchases tend to be large and sporadic, depending upon their need to build a customer base, their plans for expanding their networks, the availability of financing, and the effects of regulatory and business conditions in the countries in which they operate. As a result, their purchase decisions can be unpredictable and subject to unanticipated changes. Our results, in turn, tend to fluctuate unpredictably. This tendency has been amplified by conditions arising from the current uncertain economic environment.

Current economic conditions have made it more difficult to make reliable estimates of future revenues. Fluctuations in our revenues can lead to even greater fluctuations in our operating profits. We budget expense levels on our expectations of long-term future revenue. These budgets reflect the substantial investments in financial, engineering, manufacturing and logistics support resources we must make to support large customers, even though we are unsure of the volume, duration or timing of their purchases. In addition, we continue to make substantial expenditures on the development of new and enhanced products. Any substantial adjustment to expenses to account for lower levels of revenue is difficult and takes time. Consequently if our revenue does decline, in the short run our levels of inventory, operating expenses and general overhead would be high relative to our revenue, reducing our profitability, and perhaps resulting in operating losses.

Our Future Success Will Depend on Our Ability to Acquire New Customers

Historically, a large percentage of our sales have been made to emerging carriers, many of which have recently begun to experience severe financial difficulties. Consequently, we expect our sales to emerging carriers to be reduced, and our future success will depend on our ability to increase our sales to incumbent carriers, including, in the United States, the regional Bell operating companies (“RBOCs”), and abroad, the large, traditional telecommunications operators (“TOs”), many of which were formerly government-owned “post, telephone and telegraph” enterprises. These large companies typically require longer sales cycles, many have long-standing supplier relationships with other vendors, and our experience in selling to them is limited. If we do not succeed in penetrating this segment of the market, our business could suffer.

We May Not Be Able to Successfully Complete Development and Achieve Commercial Acceptance of New Products

It is necessary for us to continually enhance our products Certain enhancements to our products are in the development phase and are not yet ready for commercial manufacturing or deployment. For example, we expect to offer additional feature enhancement releases of the MultiWave CoreDirector product line over the life of the product and we expect to continue to enhance features of our MultiWave CoreStream, MultiWave Metro and MultiWave MetroDirector K2 products over the life of these products. The maturing process from laboratory prototype to customer trials, and subsequently to general availability, involves a number of steps, including:

	•		completion of product development;

	•		the qualification and multiple sourcing of critical components, including ASICs;

	•		validation of manufacturing methods and processes;

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

	•		validation of software; and

	•		establishment of systems integration and systems test validation requirements.

Each of these steps in turn presents serious risks of failure, rework or delay, any one of which could decrease the speed and scope of product introduction and marketplace acceptance of the product. Specialized ASICs and intensive software testing and validation are key to the timely introduction of enhancements to the MultiWave CoreDirector and MultiWave MetroDirector K2 product lines; and schedule delays are common in the final validation phase, as well as in the manufacture of specialized ASICs. In addition, unexpected intellectual property disputes, failure of critical design elements, and a host of other execution risks may delay or even prevent the introduction of these products. If we do not develop and successfully introduce these products in a timely manner, our business, financial condition and results of operations would be harmed.

The markets for our MultiWave CoreDirector and MultiWave MetroDirector K2 product lines are relatively new. We are only beginning to establish commercial acceptance of these products, and we cannot be certain that the substantial sales and marketing efforts necessary to achieve commercial acceptance in traditionally long sales cycles will be successful. If the markets for these products do not develop, or the products are not accepted by the market, our business, financial condition and results of operations would suffer. We have recently written down the value of the goodwill associated with our acquisition of Cyras, the source of our MultiWave MetroDirector K2 product, in recognition of what we believe to be a significant and permanent decline in the market for these types of products.

We Face Intense Competition which Could Hurt Our Sales and Profitability

The market for optical networking equipment is extremely competitive. Competition in the optical networking market is based on varying combinations of price, functionality, software functionality, manufacturing capability, installation, services, scalability and the ability of the system solution to meet customers’ immediate and future network requirements. A small number of very large companies, including Alcatel, Cisco Systems, Fujitsu Group, Hitachi, Lucent Technologies, NEC Corporation, Nortel Networks, Siemens AG and Telefon AB LM Ericsson, have historically dominated the telecommunications equipment industry. They all have substantial financial, marketing, manufacturing and intellectual property resources and greater resources than CIENA to develop or acquire new technologies. They also often have existing relationships with our potential customers.

Because we sell systems that compete directly with product offerings of these companies, and in some cases displace or replace their equipment, we represent a competitive threat. The continued expansion of our product offerings with the MultiWave CoreDirector and MultiWave MetroDirector K2 product lines and enhancements to our MultiWave CoreStream and MultiWave Metro product lines likely will increase this perceived threat. The recent decline in the market for optical networking equipment has resulted in even greater competitive pressures. We expect that the aggressive tactics we have confronted on the part of many of these competitors will continue, and perhaps become more severe. These tactics include:

	•		price discounting; particularly when a competitor is selling used equipment or inventory that a competitor has written down or written off;

	•		early announcements of competing products and other marketing efforts;

	•		“one-stop shopping” options;

	•		customer financing assistance;

	•		marketing and advertising assistance; and

	•		intellectual property disputes.

These tactics can be particularly effective in a highly concentrated customer base such as ours. Our customers are under increasing competitive pressure to deliver their services at the lowest possible cost. This pressure may result in the pricing of optical networking systems becoming a more important factor in customer decisions, which may favor larger competitors that can spread the effect of price discounts in their optical networking products across a larger array of products and services and across a larger customer base than ours. If we are unable to offset any reductions in the average sales price for our products by a reduction in the cost of our products, our gross profit margins will be adversely affected. Our inability to compete successfully against our competitors and maintain our gross profit margins would harm our business, financial condition and results of operations.

Many of our customers have indicated that they intend to establish a relationship with at least two vendors for optical networking products. With respect to customers for whom we are the only supplier of intelligent optical products, we do not know when or if these customers will select a second vendor or what impact the selection might have on purchases from us. If a second optical networking supplier is chosen, these customers could reduce their purchases from us, which could in turn have a material adverse effect on us.

New competitors are emerging to compete with our existing products as well as our future products. We expect new competitors to continue to emerge as the optical networking market continues to expand. These companies may achieve commercial availability of their products more quickly due to the narrow and exclusive focus of their efforts. Several of these competitors have raised significant cash and they have in some cases offered stock in their companies, positions on technical advisory boards, or have provided significant vendor financing to attract new customers. Our inability to compete successfully against these companies would harm our business, financial condition and results of operations.

If We Fail to Respond Rapidly to Technological Changes, Our Products Will Become Obsolete, Damaging Our Short-Term Prospects and Threatening Our Long-Term Survival

The market for optical networking products is likely to be characterized by rapid technological change, frequent introductions of new products, and recurring changes in customer requirements. To succeed in this market, we must continue to develop new products and new features for existing products. Doing so is difficult and costly, and there is no assurance that we will continue to be successful. In addition, we must be able to identify and gain access to promising new technologies. A failure to keep pace with technological advances would impair the competitiveness of our products and sooner or later do serious harm to our business.

Several of our new products, including the MultiWave CoreDirector, the MultiWave MetroDirector K2 and enhancements to the MultiWave CoreStream and MultiWave Metro, are based on complex technology which could result in unanticipated delays in the development, manufacturing or deployment of these products. Our LightWorks initiative, which involves modifying these products to enable customers to implement a new type of network architecture, entails similar development risks.

Our customers often require extensive testing of new products before accepting them, and we are typically unable to recognize revenue until the tests are completed satisfactorily. The certification process for new telecommunications equipment used in the networks of the RBOCs and TOs tends to be particularly lengthy and difficult. Complying with these certification requirements may involve unanticipated delays that could adversely affect the timing of our ability to sell our products to these larger carriers.

Concentration of Customers.

Although the number of customers who make purchases from us continues to grow, a substantial fraction of our revenues continues to come from sales to a small number of customers. In fiscal 2001, 50.5% of our revenues came from our two most significant customers, Sprint and Qwest. The loss of, or a substantial reduction in purchases by, either of these customers could reduce our revenues materially. Both of these companies have been affected to some extent by the current economic recession and the even more difficult conditions in the communications industry. The communications industry is, moreover, undergoing a period of consolidation. It is possible that either of these customers could become a party to a merger or other business combination. The distraction and uncertainty inevitably attendant on such a transaction could delay or alter decisions on network deployments or capital expenditures, and this could result in delayed or reduced purchases from us.

We Are Exposed to the Credit Risk of Our Customers

Industry and economic conditions have weakened the financial position of some of our customers. To sell to some of these customers we may be required to take risks of uncollectable accounts. While we monitor these situations carefully and attempt to take appropriate measures to protect ourselves, it is possible that we may have to write down or write off doubtful accounts. Such write-downs or write-offs, if large, could have a material adverse effect on our operating results and financial condition.

We also continue to experience demands from customer that we finance sales to them. While we have done only a limited amount of such financing in the past, the increasingly competitive environment in which we are now operating may require us to engage in more customer financing in the future. Our ability to recognize revenue from financed sales will depend on the relative financial condition of the specific customer, among other factors. Further, we will need to evaluate the collectability of receivables from these customers if their financial condition deteriorates in the future. Any change in the financial condition of customers to which we provide financing could have a material adverse effect on our operating results and financial condition.

Our Strategy Involves Pursuing Strategic Acquisitions and Investments that May Not Be Successful

Our business strategy includes acquiring or making strategic investments in other companies with a view to expanding our portfolio of products and services, acquiring new technologies, and accelerating the development of new or improved products. To do so, we may issue equity that would dilute our current shareholders’ percentage ownership or incur debt or assume indebtedness. In addition, we may incur significant amortization expenses related to intangible assets. In the fourth quarter fiscal 2001 we incurred a significant write-off of goodwill associated with our Cyras acquisition completed in March 2001.

Acquisitions and strategic investments involve numerous risks, including difficulties in integrating the operations, technologies, and products of the acquired companies; diversion of management’s attention from our core business; potential difficulties in completing projects of the acquired company; the potential loss of key employees of the acquired company; and dependence on unfamiliar or relatively small supply partners. In addition acquisitions and strategic investments may involve risks of entering markets in which we have no or limited direct prior experience and where competitors in such markets have stronger market positions and of obtaining insufficient revenues to offset increased expenses associated with acquisitions. Mergers and acquisitions are inherently risky. Not all of those we have made in the past have been successful; and it is possible that acquisitions we make in the future may be unsuccessful, even to the extent of materially and adversely affecting our business.

We Depend on a Limited Number of Suppliers, and for Some Items We Do Not Have a Substitute Supplier

We depend on a limited number of suppliers for components of our products, as well as for equipment used to manufacture and test our products. Our products include several high-performance components for which reliable, high-volume suppliers are particularly limited. Furthermore, some key optical and electronic components we use in our optical transport systems are currently available only from sole or limited sources, and in some cases, that source also is a competitor. Any delay in component availability for any of our products could result in delays in deployment of these products and in our ability to recognize revenues. These delays could also harm our customer relationships and our results of operations.

Failures of components affect the reliability and performance of our products and can reduce customer confidence in them, perhaps to the extent of adversely affecting our financial performance. On occasion, we have experienced delays in receipt of components and have received components that do not perform according to their specifications. Any future difficulty in obtaining sufficient and timely delivery of components could result in delays or reductions in product shipments which, in turn, could harm our business. A consolidation among suppliers of these components or adverse developments in their businesses affecting their ability to supply us, could adversely impact the availability of components on which we depend. Delayed deliveries of key components from these sources could adversely affect our business.

Any delays in component availability for any of our products or test equipment could result in delays in deployment of these products and in our ability to recognize revenue from them. These delays could also harm our customer relationships and our results of operations.

We Rely on Contract Manufacturers for Our Products

We rely on a small number of contract manufacturers to manufacture our MultiWave CoreDirector and MultiWave MetroDirector K2 product lines and some of the components for our other products. The qualification of these manufacturers is an expensive and time-consuming process, and these contract manufacturers build modules for other companies, including our competitors. In addition, we do not have contracts in place with many of these manufacturers. We may not be able to effectively manage our relationships with our manufacturers and we cannot be certain that they will be able to fill our orders in a timely manner. We provide forecasts of our demand to our contract manufacturers several months prior to scheduled delivery of products. If we overestimate our future product requirements, the contract manufacturers may have excess inventory, which would increase our costs. Conversely, if we underestimate our future product requirements the contract manufacturer may not have enough product to meet our customer requirements, and this could result in delays in the shipment of our products and our ability to recognize revenue. If we cannot effectively manage these manufacturers and forecast future demand, or if they fail to deliver components on time, our business may suffer.

Some of Our Suppliers Are Also Competitors

Some of our component suppliers are both primary sources for components and major competitors in the market for system equipment. For example, we buy components from Alcatel, Lucent Technologies, NEC Corporation, Nortel Networks, and Siemens AG. Each of these companies offers optical communications systems and equipment that are competitive with our products. A decline in reliability or other adverse change in these supply relationships could harm our business.

Our Ability to Compete Could Be Harmed If We Are Unable to Protect and Enforce Our Intellectual Property Rights or If We Infringe on Intellectual Property Rights of Others

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. We also enter into non-disclosure and proprietary rights agreements with our employees and consultants, and license agreements with our corporate partners, and control access to and distribution of our products, documentation and other proprietary information. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain and use our products or technology. Monitoring unauthorized use of our products is difficult and we cannot be certain that the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. If competitors are able to use our technology, our ability to compete effectively could be harmed. We are involved in an intellectual property dispute regarding the use of our technology and may become involved with additional disputes in the future. Such lawsuits can be costly and may significantly divert time and attention from some members of our personnel.

We have received, and may receive in the future, notices from holders of patents in the optical technology field that raise issues of possible infringement by our products. Questions of infringement in the optical networking equipment market often involve highly technical and subjective analysis. We cannot assure you that any of these patent holders or others will not in the future initiate legal proceedings against us, or that we will be successful in defending against these actions. We are involved in an intellectual property dispute regarding the possible infringement of our products. In the past, we have been forced to take a license from the owner of the infringed intellectual property, or to redesign or stop selling the product that includes the challenged intellectual property. If we are sued for infringement and are unsuccessful in defending the suit, we could be subject to significant damages, and our business and customer relationships could be adversely affected.

Product Performance Problems Could Limit Our Sales Prospects

The production of new optical networking products and systems with high technology content involves occasional problems as the technology and manufacturing methods mature. If significant reliability, quality or network monitoring problems develop, including those due to faulty components, a number of negative effects on our business could result, including:

	•		costs associated with reworking our manufacturing processes;

	•		high service and warranty expenses;

	•		high inventory obsolescence expense;

	•		high levels of product returns;

	•		delays in collecting accounts receivable;

	•		reduced orders from existing customers; and

	•		declining interest from potential customers.

Although we maintain accruals for product warranties, actual costs could exceed these amounts. From time to time, there will be interruptions or delays in the activation of our products at a customer’s site. These interruptions or delays may result from product performance problems or from aspects of the installation and activation activities, some of which are outside our control. If we experience significant interruptions or delays that we can not promptly resolve, confidence in our products could be undermined, which could harm our business.

We Face Risks Associated with our International Operations

We market, sell and service our products globally. We have established offices around the world, including in North America, Europe, Latin America and in the Asia Pacific region. We will continue to expand our international operations and enter new international markets. This expansion will require significant management attention and financial resources to develop successfully direct and indirect international sales and support channels. We may not be able to maintain or increase international market demand for our products.

International operations are subject to inherent risks, and our future results could be adversely affected by a variety of uncontrollable and changing factors. These include greater difficulty in collecting accounts receivable and longer collection periods; difficulties and costs of staffing and managing foreign operations; the impact of recessions in economies outside the United States; unexpected changes in regulatory requirements; certification requirements, reduced protection for intellectual property rights in some countries; potentially adverse tax consequences; political and economic instability; trade protection measures and other regulatory requirements; service provider and government spending patterns; and natural disasters. Such factors could have a material adverse impact on our operating results and financial condition.

Leverage and Debt Service Obligations May Adversely Affect Our Cash Flow and Our Ability to Repay or Repurchase our Notes

We have approximately $840 million of outstanding principal indebtedness, primarily related to notes offered by us and the assumption of notes from the acquisition of Cyras Systems, Inc. As a result of this indebtedness, we have significant principal and interest payment obligations. There is the possibility that we may be unable to generate sufficient cash to pay the principal of, interest on and other amounts due in respect of our indebtedness, including the notes, when due. We may also add equipment loans and lease lines to finance capital expenditures and may obtain additional long-term debt, working capital lines of credit and lease lines.

Our leverage could have important negative consequences, including:

	•		increasing our vulnerability to general adverse economic and industry conditions;

	•		limiting our ability to obtain additional financing;

	•		requiring the dedication of a substantial portion of our expected cash flow from operations to service our indebtedness, thereby reducing the amount of our expected cash flow available for other purposes, including capital expenditures;

	•		limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we compete;

	•		placing us at a possible competitive disadvantage relative to less leveraged competitors and competitors that have better access to capital resources; and

	•		making it difficult or impossible for us to pay the principal amount of the notes at maturity or the repurchase price of the notes upon a change of control, thereby causing an event of default under the indenture.

Our Stock Price May Exhibit Volatility

Our common stock price has experienced substantial volatility in the past, and is likely to remain volatile in the future. Volatility can arise as a result of the activities of short sellers and risk arbitrageurs, and may have little relationship to our financial results or prospects. Volatility can also result from any divergence between our actual or anticipated financial results and published expectations of analysts, and announcements that we, our competitors, or our customers may make.

Divergence between our actual results and our anticipated results, analyst estimates and public announcements by us, our competitors, or by customers will occur from time to time in the future, with resulting stock price volatility, irrespective of our overall year-to-year performance or long-term prospects. As long as we continue to depend on a limited customer base, and particularly when a substantial majority of their purchases consist of newly-introduced products, there is substantial chance that our quarterly results will vary widely.

Forward Looking Statements

Some of the statements contained, or incorporated by reference, in this annual report discuss future expectations, contain projections of results of operations or financial condition or state other “forward-looking” information. Those statements are subject to known and unknown risks, uncertainties and other factors that could cause the actual results to differ materially from those contemplated by the statements. The “forward-looking” information is based on various factors and was derived using numerous assumptions. In some cases, you can identify these so-called “forward-looking statements” by words like “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of those words and other comparable words. You should be aware that those statements only reflect our predictions. Actual events or results may differ substantially. Important factors that could cause our actual results to be materially different from the forward-looking statements are disclosed throughout this report, particularly under the heading “Risk Factors” above.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

The following discussion about the Company’s market risk disclosures involves forward-looking statements. Actual results could differ materially from those projected in the forward-looking statements. The Company is exposed to market risk related to changes in interest rates and foreign currency exchange rates. The Company does not use derivative financial instruments for speculative or trading purposes.

Interest Rate Sensitivity. The Company maintains a short-term and long-term investment portfolio. These available-for-sale securities are subject to interest rate risk and will fall in value if market interest rates increase. If market interest rates were to increase immediately and uniformly by 10 percent from levels at October 31, 2001, the fair value of the portfolio would decline by approximately $115.5 million.

Foreign Currency Exchange Risk. As a global concern, the Company faces exposure to adverse movements in foreign currency exchange rates. These exposures may change over time as business practices evolve and if our exposure increases, adverse movement in foreign currency exchange rates could have a material adverse impact on the Company’s financial results. Historically the Company’s primary exposures have been related to non-dollar denominated operating expenses in Europe and Asia where the Company sells primarily in U.S. dollars. The Company is prepared to hedge against fluctuations in foreign currency if this exposure becomes material. As of October 31, 2001, the assets and liabilities of the Company related to non-dollar denominated currencies were not material. Therefore we do not expect an increase or decrease of 10% in the foreign exchange rate would have a material impact on the Company’s financial position.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Stockholders of CIENA Corporation

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of cash flows and of changes in stockholders’ equity present fairly, in all material respects, the financial position of CIENA Corporation and its subsidiaries at October 31, 2001 and 2000, and the results of their operations and their cash flows for each of the three years in the period ended October 31, 2001 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

CIENA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES

Description of Business

CIENA is a leader in the intelligent optical networking equipment market. The Company offers a portfolio of products for communications service providers worldwide. CIENA’s customers include long-distance carriers, competitive and incumbent local exchange carriers, Internet service providers, wireless and wholesale carriers. CIENA offers optical transport and intelligent optical switching systems that enable service providers to provision, manage and deliver high-bandwidth services to their customers. CIENA has pursued a strategy to develop and leverage the power of disruptive technologies to change the fundamental economics of building carrier-class tele- and data-communications networks, thereby providing our customers with a competitive advantage. CIENA’s intelligent optical networking products are designed to enable carriers to deliver any time, any size, any priority bandwidth to their customers.

Principles of Consolidation

The Company has seventeen wholly owned U.S. and international subsidiaries which have been consolidated in the accompanying financial statements. On March 29, 2001, CIENA acquired all of the outstanding capital stock, and assumed the options of Cyras Systems, Inc. (“Cyras”), a Delaware company based in Fremont, California. The Company completed a merger with Omnia Communications, Inc. (“Omnia”), a Delaware company headquartered in Marlborough, Massachusetts, on July 1, 1999. On March 31, 1999 the Company completed a merger with Lightera Networks, Inc. (“Lightera”), a Delaware company headquartered in Cupertino, California. The Cyras transaction constituted a tax-free reorganization and was recorded using the purchase accounting method. The Omnia and Lightera transactions constituted tax-free reorganizations and have been accounted for as poolings of interests under Accounting Principles Board Opinion No. 16. Accordingly, all prior period consolidated financial statements presented have been restated to include the combined results of operations, financial position and cash flows of Omnia and Lightera as though they had been a part of CIENA.

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation.

Fiscal Year

The Company has a 52 or 53 week fiscal year, which ends on the Saturday nearest to the last day of October in each year (November 3, 2001, October 28, 2000, and October 30, 1999). For purposes of financial statement presentation, each fiscal year is described as having ended on October 31. Fiscal 2001 was comprised of 53 weeks. Fiscal 2000 and 1999 were comprised of 52 weeks. Prior to the merger, Omnia’s fiscal year ended on December 31.

The fiscal year ended October 31, 1999 contains two months of Omnia’s financial results, which are also recorded in the fiscal year ending October 31, 1998. The net loss for these two months, November and December 1998, was $1.6 million.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires the Company to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, together with amounts disclosed in the related notes to the financial statements. Actual results could differ from the recorded estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents.

Investments

CIENA’s short-term and long-term investments are classified as available-for-sale as of October 31, 2001 and are reported at fair value, with unrealized gains and losses, net of tax, recorded in accumulated other comprehensive income. Realized gains or losses and declines in value determined to be other than temporary, if any, on available-for-sale securities will be reported in other income or expense as incurred. As of October 31, 2000, CIENA’s marketable securities were classified as held-to-maturity securities and were recorded at their amortized cost.

CIENA also has certain other minority equity investments in non-publicly traded companies. These investments are generally carried at cost as CIENA owns less than 20% of the voting equity and does not have the ability to exercise significant influence over these companies. As of October 31, 2000 and October 31, 2001, $3.0 million and $16.1 million of these investments are included in other long-term assets, respectively. These investments are inherently high risk as the market for technologies or product manufactured by these companies are usually early stage at the time of the investment by CIENA and such markets may never be significant. CIENA could lose its entire investment in certain or all of these companies. CIENA monitors these investments for impairment and makes appropriate reductions in carrying values when necessary. No write-downs were recorded during fiscal 2000 or fiscal 2001.

Inventories

Inventories are stated at the lower of cost or market, with cost determined on the first-in, first-out basis. The Company records a provision for excess and obsolete inventory whenever such an impairment has been identified.

Equipment, Furniture and Fixtures

Equipment, furniture and fixtures are recorded at cost. Depreciation and amortization are computed using the straight-line method over useful lives of 2-5 years for equipment, furniture and fixtures and 2-10 years for leasehold improvements.

Internal use software and web site development costs are capitalized in accordance with Statement of Position (SOP) No. 98-1, “Accounting for the Costs of Computer Software Developed or Obtained for Internal Use,” and Emerging Issues Task Force (EITF) Issue No. 00-02, “Accounting for Web Site Development Costs.” Qualifying costs incurred during the application development stage, which consist primarily of outside services and purchased software license costs, are capitalized and amortized over the estimated useful life of the asset.

Goodwill and Purchased Intangible Assets

The Company has recorded goodwill and purchased intangible assets from several acquisitions. See Note 7. Goodwill and purchased intangible assets are carried at cost less accumulated amortization. Amortization is computed using the straight-line method over the economic lives of the respective assets, generally three to seven years. It is the Company’s policy to assess periodically the carrying amount of its goodwill and purchased intangible assets to determine if there has been an impairment to their carrying value. Impairments of goodwill and other intangibles assets are determined in accordance with Statement of Financial Accounting Standard No. 121, “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of” (“SFAS No. 121”). The Company has recorded goodwill amortization expense of $3.2 million, $3.2 million, and $177.8 million for fiscal years 1999, 2000 and 2001, respectively.

Concentrations

Substantially all of the Company’s cash and cash equivalents, short-term and long-term investments, are custodied at four major U.S. financial institutions. The majority of the Company’s cash equivalents consist of U.S. Government Federal Agency Securities, short-term marketable securities, and overnight repurchase agreements. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally these deposits may be redeemed upon demand and, therefore, bear minimal risk.

Historically, the Company has relied on a limited number of customers for a substantial portion of its revenue. During fiscal year 2001, Sprint and Qwest Communications each accounted for at least 10% or more of CIENA’s revenue and combined accounted for 50.5% of the Company’s fiscal 2001 revenue. During fiscal year 2000, Sprint, Qwest Communications and GTS Network Ltd. each accounted for at least 10% of CIENA’s revenue and all three combined accounted for 60.9% of the Company’s fiscal 2000 revenue. During fiscal year 1999 Sprint, MCI WorldCom, and GTS Network Ltd. each accounted for at least 10% of CIENA’s revenue and all three combined

accounted for 46.2% of the Company’s fiscal 1999 revenue. The Company expects that a significant portion of its future revenue will continue to be generated by a limited number of customers. The loss of any one of these customers or any substantial reduction in orders by any one of these customers could materially adversely affect the Company’s financial condition or operating results. Additionally, the Company’s access to certain raw materials is dependent upon single and sole source suppliers. The inability of any supplier to fulfill supply requirements of the Company could affect future results.

CIENA performs ongoing credit evaluations of its customers and generally does not require collateral from its customers. CIENA maintains an allowance for potential losses on a specific identification basis. CIENA’s allowance for doubtful accounts as of October 31, 2001 and October 31, 2000 was $1.5 million and $29.6 million, respectively. Approximately $27.8 million of the October 31, 2000 balance relates to provisions made for doubtful accounts associated with iaxis Limited, one of CIENA’s European customers. In September 2000, CIENA was informed that an administrative order had been issued by a London court against iaxis Limited. As a result of this order, joint administrators were appointed to manage the business of iaxis Limited while they marketed the business for sale and formulated a reorganization of the company. In November 2000, CIENA was notified that Dynegy Inc. and its subsidiaries had entered into a proposed agreement to acquire the assets and stock of iaxis Limited from the administrators. As a consequence of the terms of (a) the proposed agreement between the administrators of iaxis Limited and Dynegy, and of (b) a related sales agreement between CIENA and Dynegy, CIENA expected to realize approximately $8.9 million of the gross outstanding accounts receivable balance due from iaxis Limited as of October 31, 2000. In July 2001 CIENA recovered approximately $15.4 million of the gross outstanding accounts receivable balance due from iaxis Limited primarily through the sales agreement with Dynegy. Accordingly, CIENA recognized a reduction in the provision for doubtful accounts of $6.6 million during fiscal year 2001.

As of October 31, 2001, the trade accounts receivable included three customers who each accounted for 38%, 18%, and 15% of the trade accounts receivable, respectively. As of October 31, 2000, the trade accounts receivable included three customers who each accounted for 28%, 16%, and 13% of the trade accounts receivable, respectively.

Revenue Recognition

CIENA recognizes product revenue in accordance with the shipping terms specified and where collection is reasonably assured. For transactions where CIENA has yet to obtain customer acceptance, revenue is deferred until the terms of acceptance are satisfied. Revenue for installation services is recognized as the services are performed unless the terms of the supply contract combine product acceptance with installation, in which case revenues for installation services are recognized when the terms of acceptance are satisfied and installation is completed. Revenues from installation service fixed price contracts are recognized on the percentage-of-completion method, measured by the percentage of costs incurred to date compared to estimated total costs for each contract. Amounts received in excess of revenue recognized are included as deferred revenue in the accompanying balance sheets. For transactions involving the sale of software, revenue is recognized in accordance with Statement of Position No. 97-2 (SOP 97-2), “Software Revenue Recognition”, including deferral of revenue recognition in instances where vendor specific objective evidence for undelivered elements is not determinable. For distributor sales where risks of ownership have not transferred, CIENA recognizes revenue when the product is shipped through to the end user.

Revenue-Related Accruals

The Company provides for the estimated costs to fulfill customer warranty and other contractual obligations upon the recognition of the related revenue. Such reserves are determined based upon actual warranty cost experience, estimates of component failure rates, and management’s industry experience. The Company’s sales contracts generally do not permit the right of return of product by the customer after the product has been accepted.

Research and Development

The Company charges all research and development costs to expense as incurred.

Advertising Costs

The Company expenses all advertising costs as incurred.

Income Taxes

The Company accounts for income taxes in accordance with Statement of Financial Accounting Standards No. 109 (SFAS No. 109), “Accounting for Income Taxes”. SFAS No. 109 is an asset and liability approach that requires the recognition of deferred tax assets and liabilities 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 carry forwards. In estimating future tax consequences, SFAS No. 109 generally considers all expected future events other than the enactment of changes in tax laws or rates. Valuation allowances are provided if, based upon 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. Tax savings resulting from deductions associated with stock options and certain stock warrants are credited directly to additional paid in capital when realization of such benefit is fully assured and to deferred tax liabilities prior to such point. See Note 13.

Fair Value of Financial Instruments

The carrying amounts of the Company’s financial instruments, which include short-term and long-term investments, accounts receivable, accounts payable, and other accrued expenses, approximate their fair values due to their short maturities.

Foreign Currency Translation

The majority of the Company’s foreign branches and subsidiaries use the U.S. dollar as their functional currency, as the U.S. parent exclusively funds the branches and subsidiaries’ operations with U.S. dollars. 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. Resulting translation adjustments are recorded directly to a separate component of stockholders’ equity. Where the U.S. dollar is the functional currency, translation adjustments are recorded in other income. The net gain (loss) on foreign currency re-measurement and exchange rate changes for fiscal 1999, 2000 and 2001 was immaterial for separate financial statement presentation.

Computation of Basic Net Income (Loss) per Common Share and Diluted Net Income (Loss) per Common and Dilutive Potential Common Share

The Company calculates earnings per share in accordance with the Statement of Financial Accounting Standards No. 128, “Earnings per Share” (SFAS No. 128). SFAS No. 128 simplifies the earnings per share (EPS) computation and replaces the presentation of primary EPS with a presentation of basic EPS. This statement also requires dual presentation of basic and diluted EPS on the face of the income statement for entities with a complex capital structure and requires a reconciliation of the numerator and denominator used for the basic and diluted EPS computations. See Note 10.

Software Development Costs

Statement of Financial Accounting Standards No. 86, “Accounting for the Costs of Computer Software to be Sold, Leased or Otherwise Marketed” (“SFAS No. 86”), requires the capitalization of certain software development costs 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 over the estimated product life. The Company defines technological feasibility as being attained at the time a working model is completed. To date, the period between achieving technological feasibility and the general availability of such software has been short and software development costs qualifying for capitalization have been insignificant. Accordingly, the Company has not capitalized any software development costs.

Accounting for Stock Options

In October 1995, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 123 (SFAS No. 123), “Accounting for Stock-Based Compensation”. SFAS No. 123 allows companies to either account for stock-based compensation under the new provisions of SFAS No. 123 or using the intrinsic value method provided by Accounting Principles Board Opinion No. 25 (APB No. 25), “Accounting for Stock Issued to Employees”, but requires pro forma disclosure in the footnotes to the financial statements as if the measurement provisions of SFAS No. 123 had been adopted. The Company has elected to continue to account for its stock based compensation in

accordance with the provisions of APB No. 25 as interpreted by FASB Interpretation No. 44, “Accounting for Certain Transactions Involving Stock Compensation, and Interpretation of APB Opinion No. 25”, (“FIN 44”) and present the pro forma disclosures required by SFAS No. 123. See Note 13.

Segment Reporting

In June 1997, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 131 (SFAS No. 131), “Disclosures about Segments of an Enterprise and Related Information”. SFAS No. 131 establishes annual and interim reporting standards for operating segments of a company. It also requires entity-wide disclosures about the products and services an entity provides, the material countries in which it holds assets and reports revenues, and its major customers. The Company is not organized by multiple operating segments for the purpose of making operating decisions or assessing performance. Accordingly, the Company operates in one operating segment and reports only certain enterprise-wide disclosures.

Newly Issued Accounting Standards

In July 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 141 “Business Combinations” (SFAS No. 141) and Statement of Financial Accounting Standards No. 142 “Goodwill and Other Intangible Assets” (SFAS No. 142). SFAS No. 141 addresses financial accounting and reporting for business combinations. This statement requires the purchase method of accounting to be used for all business combinations, and prohibits the pooling-of-interests method of accounting. This statement is effective for all business combinations initiated after June 30, 2001 and supercedes APB Opinion No. 16, “Business Combinations” as well as Financial Accounting Standards Board Statement of Financial Accounting Standards No. 38, “Accounting for Preacquisition Contingencies of Purchased Enterprises”.

Reclassification

Certain prior year amounts have been reclassified to conform to current year consolidated financial statement presentation.

(2) BUSINESS COMBINATIONS

Cyras

On March 29, 2001, CIENA acquired all of the outstanding capital stock, and assumed the options of Cyras Systems, Inc. (“Cyras”), a privately held provider of next-generation optical networking systems based in Fremont, California. The purchase price was approximately $2.2 billion and consisted of the issuance of approximately 26.1 million shares of CIENA common stock, the assumption of approximately 1.9 million stock options and the indirect assumption of $150 million principal amount of Cyras’s convertible subordinated indebtedness. Cyras is designing and developing next-generation optical networking solutions for telecommunications carriers. The Cyras K2 product, which has become CIENA’s MultiWave MetroDirector K2, enables carriers of metropolitan area networks to consolidate multiple legacy network elements into a single switching platform.

The transaction was recorded using the purchase accounting method with the allocation of the purchase price summarized below (in thousands):


Tangible assets		$	80,712
Deferred tax asset			37,201
Developed technology			47,700
In-process research and development			45,900
Workforce			11,600
Goodwill			2,059,899
Deferred stock compensation			98,456
Acquisition costs			(14,790	)
Other assumed liabilities			(21,124	)
Convertible subordinated notes			(167,700	)
Employee loans			7,784

	Total purchase price	$	2,185,638

The amortization period for the goodwill and intangibles, based on management’s estimate of the useful life of the acquired technology, is three to seven years. As a result of the issuance of SFAS No. 142, amortization related to goodwill will no longer be recorded in subsequent fiscal years.

In connection with the Cyras acquisition, the Company recorded a $45.9 million charge in the period ended April 30, 2001 for in-process research and development. This represents the estimated value of purchased in-process technology related to Cyras’s K2 product development that had not yet reached technological feasibility and had no alternative future use at the time of the acquisition. The amount of purchase price allocated to in-process research and development was determined using the discounted cash flow method. This method consisted of estimating future net cash flows attributable to in-process K2 technology for a discrete projection period and discounting the net cash flows back to their present value. The discount rate includes a factor that takes into account the uncertainty surrounding the successful development of the purchased in-process technology.

In connection with the Cyras acquisition, the Company recorded a $47.7 million intangible asset related to developed technology. This represents the estimated value of the portion of the purchased technology for which development had been completed. The amount of purchase price allocated to purchased technology was determined using the income approach. This method consisted of estimating future net cash flows attributable to existing K2 technology for a discrete projection period and discounting the net cash flows back to their present value.

In conjunction with the Cyras acquisition, the Company recorded deferred stock compensation of $98.4 million. The unamortized deferred stock compensation was $53.6 million at October 31, 2001.

The following unaudited pro forma data summarizes the results of operations for the period indicated as if the Cyras acquisition had been completed as of the beginning of the periods presented. The unaudited pro forma data gives effect to actual operating results prior to the acquisition, adjusted to include the pro forma effect of amortization of intangibles, deferred stock compensation costs, the elimination of the charge for acquired in-process research and development, the tax effects to the pro forma adjustments and the recognition of the tax benefits arising from Cyras’s net operating loss carry forwards. These pro forma amounts do not purport to be indicative of the results that would

have actually been obtained if the acquisition occurred as of the beginning of the periods presented or that may be obtained in the future (in thousands, except per share data).

Omnia

On July 1, 1999, the Company completed a merger with Omnia in a transaction valued at approximately $483 million. Omnia is a telecommunications equipment supplier which focuses on developing solutions to allow public telephone network operators to offer services cost effectively over integrated metropolitan fiberoptic access and transport networks. Under the terms of the merger agreement, the Company acquired all of the outstanding shares and assumed the stock options of Omnia in exchange for approximately 30.4 million shares of CIENA common stock and 1.6 million CIENA shares issuable upon exercise of stock options. The transaction constituted a tax-free reorganization and has been accounted for as a pooling of interests under Accounting Principles Board Opinion No. 16. Accordingly, all prior period consolidated financial statements presented have been restated to include the combined results of operations, financial position and cash flows of Omnia as though it had been a part of CIENA.

The following table shows the separate historical results of CIENA and Omnia for the periods prior to the consummation of the merger of the two entities. No financial information has been presented for the fiscal year ended 1996 as Omnia did not commence operations until June 1997. Omnia’s fiscal year end was December 31. CIENA’s results for the years ended October 31, 1997 and 1998 include Omnia’s financial results from June 3, 1997 (date of inception) to December 31, 1997 and January 1, 1998 to December 31, 1998, respectively (in thousands).

Lightera

On March 31, 1999 the Company completed a merger with Lightera in a transaction valued at approximately $459 million. Lightera is a developer of carrier class optical core switches for fiberoptic communications networks. Under the terms of the merger agreement, the Company acquired all of the outstanding shares and assumed outstanding stock options and warrants of Lightera in exchange for approximately 35.0 million shares of CIENA common stock and 5.8 million CIENA shares issuable upon exercise of stock options and warrants. The transaction constituted a tax-free reorganization and has been accounted for as a pooling of interests under Accounting Principles Board Opinion No. 16. Accordingly, all prior period consolidated financial statements presented have been restated to include the combined results of operations, financial position and cash flows of Lightera as though it had been a part of CIENA.

The following table shows the separate historical results of CIENA and Lightera for the periods prior to the consummation of the merger of the two entities.

(3) RESTRUCTURING COSTS AND IMPAIRMENT CHARGES

During the fiscal year ended October 31, 2001 the Company recorded a restructuring charge of $15.4 million relating to consolidation of excess facilities. The consolidation of excess facilities included the closure of certain manufacturing warehouse facilities and the consolidation of certain operational centers related to business activities that have been restructured. The charge included $7.0 million primarily related to lease terminations and non-cancelable lease costs and also included an $8.4 million write-down related to property and equipment consisting primarily of leasehold improvements and production equipment.

As part of our review of financial results for fiscal 2001, we performed an assessment of the carrying value of our long-lived assets including significant amounts of goodwill and other intangible assets recorded in connection with the acquisition of Cyras. The assessment was performed pursuant to Statement Financial Accounting Standards No. 121 “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of” (SFAS 121) because of the significant negative industry and economic trends affecting both the Company’s current operations and expected future sales of MultiWave MetroDirector K2 as well as the general decline of technology valuations. The conclusion of that assessment was that the decline in market conditions within the Company’s industry was significant and other than temporary. As a result, the Company recorded a charge of $1.7 billion to reduce goodwill during the fourth quarter of 2001 based on the amount by which the carrying amount of these assets exceeded their fair value. The write down is related to the goodwill associated with the Cyras transaction. Fair value was determined based on discounted future cash flows for the operating entity, which had separately identifiable cash flows. The cash flow periods used were six years, applying annual growth rates of 25% to 100%. The discount rate used was 11.3%, and the terminal value was estimated based upon terminal growth rates of 4%. The assumptions supporting the estimated future cash flows, including the discount rate and estimated terminal value reflect management’s best estimates. The discount rate was based upon the Company’s weighted average cost of capital as adjusted for the risks associated with its operations.

(8) CONVERTIBLE NOTES PAYABLE

On February 9, 2001, CIENA completed a public offering of 3.75% convertible notes, in an aggregate principal amount of $690 million, due February 1, 2008. Interest is payable on February 1 and August 1 of each year beginning August 1, 2001. The notes may be converted into shares of CIENA’s common stock at any time before their maturity or their prior redemption or repurchase by CIENA. The conversion rate is 9.5808 shares per each $1,000 principal amount of notes, subject to adjustment in certain circumstances. On or after the third business day after February 1, 2004, CIENA has the option to redeem all or a portion of the notes that have not been previously converted at the following redemption prices (expressed as percentage of principle amount):


		Redemption
Period		Price

Beginning on the third business day after February 1, 2004 and
	ending on January 31, 2005		102.143	%
Beginning on February 1, 2005 and ending on January 31, 2006			101.607	%
Beginning on February 1, 2006 and ending on January 31, 2007			101.071	%
Beginning on February 1, 2007 and ending on January 31, 2008			100.536	%

In August 2000, Cyras issued $150 million of 4.5% convertible subordinated notes due August 15, 2005. Interest is payable on February 15 and August 15 of each year, beginning February 15, 2001. CIENA indirectly assumed the convertible subordinated notes on March 29, 2001 as a result of its acquisition of Cyras. CIENA recorded the estimated fair value of the notes on the date of the acquisition at $167.7 million. The notes may be converted into shares of CIENA’s common stock at any time before their maturity or their prior redemption. The conversion rate is 6.9137 shares per each $1,000 principal amount of notes, subject to adjustment in certain circumstances. Cyras Systems LLC is the successor to Cyras Systems Inc. and a wholly owned subsidiary of CIENA. If an IPO of Cyras Systems LLC has not occurred on or before March 31, 2002, CIENA will be obligated to make an offer to repurchase the notes at 118.9% of the principal balance thereof on April 30, 2002. CIENA is accreting the redemption premium over the remaining period to April 30, 2002, such that the carrying value of the notes equals the redemption price at the date of the redemption obligation. Accretion of the redemption premium was $6.2 million during the fiscal year 2001.

(9) ACCRUED LIABILITIES

Accrued liabilities are comprised of the following (in thousands):

(10) EARNINGS (LOSS) PER SHARE CALCULATION

The following is a reconciliation of the numerators and denominators of the basic net income (loss) per common share (“basic EPS”) and diluted net income (loss) per common and dilutive potential common share (“diluted EPS”). Basic EPS is computed using the weighted average number of common shares outstanding. Diluted EPS is computed using the weighted average number of common shares outstanding, stock options and warrants using the treasury stock method (in thousands except per share amounts).

Basic EPS		$	(0.01	)	$	0.29	$	(5.75	)

Diluted EPS		$	(0.01	)	$	0.27	$	(5.75	)

Approximately 23.8 million, 1.2 million and 16.4 million options and restricted stock were outstanding during fiscal 1999, 2000 and 2001 respectively, but were not included in the computation of the Diluted EPS as the effect would be anti-dilutive.

(11) STOCKHOLDERS’ EQUITY

Authorized Shares

On March 12, 2001, the shareholders of the Company approved an increase to the number of authorized shares of common stock from 460 million to 980 million shares.

Stock Split

The Board of Directors authorized the splitting of the Company’s common stock on a two-for-one basis for shareholders of record on August 28, 2000 and the resulting shares from the split were distributed on September 18, 2000. All references to share and per-share data for all periods presented have been adjusted to give effect to this two-for-one stock split.

Stockholder Rights Plan

In December 1997, the Company’s Board of Directors adopted a Stockholder Rights Plan. This plan is designed to deter any potential coercive or unfair takeover tactics in the event of an unsolicited takeover attempt. It is not intended to prevent a takeover of the Company on terms that are favorable and fair to all shareholders and will not interfere with a merger approved by the Board of Directors. Each right entitles shareholders to buy a “unit” equal to one one-thousandth of a share of Preferred Stock of the Company. The rights will be exercisable only if a person or a group acquires or announces a tender or exchange offer to acquire 15% or more of the Company’s common stock or if the Company enters into certain other business combination transactions not approved by the Board of Directors.

In the event the rights become exercisable, the rights plan allows for CIENA shareholders to acquire stock of the surviving corporation, whether or not CIENA is the surviving corporation, having a value twice that of the exercise price of the rights. The rights were distributed to shareholders of record in January 1998. The rights will expire December 2007 and are redeemable for $0.001 per right at the approval of the Company’s Board of Directors.

Public Offerings

On February 9, 2001, CIENA completed a public offering of 11,000,000 shares of common stock at a price of $83.50 per share less underwriters’ discounts and commissions. Net proceeds from the public offering was approximately $878.5 million, after deducting underwriting discounts, commissions and offering expenses. Pending use of the net proceeds, the Company has invested them in interest bearing, investment grade securities.

Other Offerings

During fiscal 1999 Omnia issued 368,990 shares of common stock in exchange for approximately $66,000. In fiscal 1999, Lightera issued 1,937,022 shares of common stock in exchange for approximately $104,000.

As of October 31, 2001, the Company had a $199.1 million net operating loss carry forward and a $31.3 million income tax credit which begin to expire in fiscal 2021 and 2014, respectively. Management believes that, after considering the anticipated future operating results of the Company, the net deferred tax assets will be realized. However, there cannot be complete assurance that this will occur.

The income tax provision does not reflect the tax savings resulting from deductions associated with the Company’s stock option plans. Tax benefits from exercises of stock options of approximately $11.0 million, $154.6 million and $71.6 million in fiscal 1999, fiscal 2000 and fiscal 2001, respectively, were credited directly to additional paid-in-capital.

The IRS is currently examining the Company’s federal income tax returns for fiscal 1997 and fiscal 1998. Management does not expect the outcome of these examinations to have a material adverse affect on the Company’s consolidated financial position, results of operations or cash flows.

(13) EMPLOYEE BENEFIT PLANS

Stock Incentive Plans

In August of 1999, the Company approved the 1999 Non-Officer Incentive Stock Plan (the “1999 Plan”). Under the 1999 Plan, as of October 31, 2001, 39,000,000 shares of the Company’s authorized but unissued Common Stock were reserved for options issuable to employees who are not executive officers of the Company. This number will

increase on the last day of each fiscal year by 4.2% of the number of issued and outstanding shares of common stock on that date. These options vest to the employee over four years and are exercisable once vested. Options under the 1999 Plan are categorized as non-qualified, and the exercise price for each option shall be established by the Board of Directors provided the price is not less than 85% of fair market value.

The Company has an Amended and Restated 1994 Stock Option Plan (the “1994 Plan”). Under the 1994 Plan, as of October 31, 2001, 48,560,167 shares of the Company’s authorized but unissued Common Stock were reserved for options issuable to employees. This number increases by 0.75% of the number of issued and outstanding shares of the common stock on the last day of the fiscal years 2002, 2003, and 2004. Certain of these options are immediately exercisable upon grant, and both the options and the shares issuable upon exercise of the options generally vest to the employee over a four year period. The Company has the right to repurchase any exercised and non-vested shares at the original purchase price from the employees upon termination of employment. Under the 1994 Plan, options may be incentive stock options or non-qualified options, and the exercise price for each option shall be established by the Board of Directors provided, however, that the exercise price per share shall not be not less than 100% of the fair market value.

In June 1996, the Company approved the 1996 Outside Directors Stock Option Plan (the “1996 Plan”). Under the 1996 Plan, 1,500,000 shares of the Company’s authorized but unissued Common Stock are reserved for options issuable to outside members of the Company’s Board of Directors. These options vest to the director over periods from one to three years, depending on the type of option granted, and are exercisable once vested. Under the 1996 Plan, options may be incentive stock options or non-qualified options, and the exercise price for each option shall be established by the Board of Directors provided, however, that the exercise price per share shall not be not less than the fair market value for incentive stock options and not less than 85% of fair market value for non-qualified stock options.

As a result of the Company’s purchase of Cyras, the Company assumed the Cyras 1998 Stock Plan Option Plan (“the Cyras 1998 Plan”). The Cyras 1998 Plan provided for the granting of stock options to employees and consultants of Cyras. Options granted under the Cyras 1998 Plan were either incentive stock options or non-statutory stock options. Incentive stock options (“ISO”), could be granted only to Cyras employees (including officers and directors who were also employees). Non-statutory stock options (“NSO”) could be granted to Cyras employees and consultants. The Company has reserved 2,015,783 shares of Common Stock for outstanding options under the plan. Options exercised are immediately subject to a repurchase right held by the Company which lapse over a maximum period of four years at such times and under such conditions as determined by the Board of Directors.

As a result of the Company’s merger with Omnia, the Company assumed the Omnia 1997 Stock Plan Option (“the 1997 Plan”). The 1997 Plan provided for the granting of stock options to employees and consultants of Omnia. Options granted under the 1997 Plan were either incentive stock options or non-statutory stock options. Incentive stock options (“ISO”), could be granted only to Omnia employees (including officers and directors who were also employees). Non-statutory stock options (“NSO”) could be granted to Omnia employees and consultants. The Company has reserved 1,519,778 shares of Common Stock for outstanding options under the plan. Options exercised are immediately subject to a repurchase right held by the Company which lapse over a maximum period of four years at such times and under such conditions as determined by the Board of Directors.

As a result of the Company’s merger with Lightera, the Company assumed the Lightera 1998 Stock Option Plan (“the 1998 Plan”). The 1998 Plan provided for the granting of stock options to employees and consultants of Lightera. Options granted under the 1998 Plan were either incentive stock options or non-statutory stock options. Incentive stock options (“ISO”), could be granted only to Lightera employees (including officers and directors who were also employees). Non-statutory stock options (“NSO”) could be granted to Lightera employees and consultants. The Company has reserved 5,058,322 shares of Common Stock for outstanding options under the plan. Options exercised are immediately subject to a repurchase right held by the Company which lapse over a maximum period of five years at such times and under such conditions as determined by the Board of Directors.

At October 31, 2001, approximately 1.5 million shares of Common Stock subject to repurchase by the Company had been issued upon the exercise of options and restricted stock purchase agreements, and 12.5 million of the total outstanding options were vested and not subject to repurchase by the Company upon exercise. As of October 31, 2001, approximately 66.4 million shares are available for issuance under these plans.

Employee Stock Purchase Plan

In March 1998, the shareholders approved the Corporation’s 1998 Stock Purchase Plan (“the Purchase Plan”) under which 5.0 million shares of common stock have been reserved for issuance. Eligible employees may purchase a limited number of shares of the Company’s stock at 85% of the market value at certain plan-defined dates. Approximately 424,000, 693,000 and 607,000 shares of common stock have been issued for $7.8 million, $5.8 million and $3.3 million during fiscal 2001, 2000 and 1999, respectively. As of October 31, 2001 approximately 3.3 million shares are available for issuance under this plan.

Pro forma Stock-Based Compensation

Had compensation cost for the Company’s stock option plans and the Purchase Plan been determined based on the fair value at the grant date for awards in fiscal years 1999, 2000 and 2001 consistent with the provisions of SFAS No. 123, the Company’s net income and net income per share for fiscal 2000 would have been decreased and the net loss and the net loss per share for fiscal 1999 and 2001 would have been increased to the pro forma amounts indicated below (in thousands, except per share):


		October 31,

		1999			2000			2001

Net income (loss) applicable to common stockholders –
	as reported	$	(3,924	)	$	81,387		$	(1,794,062	)

Net loss applicable to common stockholders –
	pro forma	$	(40,067	)	$	(26,244	)	$	(2,118,722	)

Basic net income (loss) per share – as reported		$	(0.01	)	$	0.29		$	(5.75	)

Basic net loss per share – pro forma		$	(0.15	)	$	(0.09	)	$	(6.79	)

Diluted net loss per share – as reported		$	(0.01	)	$	0.27		$	(5.75	)

Diluted net loss per share – pro forma		$	(0.15	)	$	(0.09	)	$	(6.79	)

The above pro forma disclosures are not necessarily representative of the effects on reported net income or loss for future years.

The weighted average fair value of each option granted under the various stock option plans for 1999, 2000 and 2001 is $9.45, $64.99 and $27.92 respectively. The fair value of each option grant is estimated on the date of grant using the Black-Scholes Option Pricing Model with the following weighted average assumptions for fiscal years 1999, 2000, and 2001:


	Employee Stock Option Plans									Employee Stock Purchase Plan
	October 31,									October 31,

	1999			2000			2001			1999			2000			2001

Expected volatility		88	%		106	%		131	%		88	%		106	%		131	%
Risk-free interest rate		5.5	%		6.1	%		3.6	%		5.5	%		6.1	%		3.6	%
Expected life (years)		2.8			2.7			2.6			0.5			0.5			0.5
Expected dividend yield		0.0	%		0.0	%		0.0	%		0.0	%		0.0	%		0.0	%

The Black-Scholes option pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option pricing models require the input of highly subjective assumptions including the expected stock price volatility. The Company uses projected volatility rates, which are based upon historical volatility rates trended into future years. Because the Company’s employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of the Company’s options.

Employee 401(k) Plan

The Company has a 401(k) defined contribution profit sharing plan. The plan covers all full-time employees who are not covered by a collective bargaining agreement where retirement benefits are subject to good faith bargaining. Participants may contribute up to 15% of pre-tax compensation, subject to certain limitations. The Company may make discretionary annual profit sharing contributions of up to the lesser of $30,000 or 25% of each participant’s compensation. The Company has made no profit sharing contributions to date. The plan also includes an employer matching contribution equal to 100% of the first 3% of participating employee contributions, with a five year vesting plan applicable to the Company’s contribution with the exception that participants vest immediately upon turning age

fifty-five. During fiscal 1999, 2000 and 2001 the Company made matching contributions of approximately $1.7 million, $2.3 million and $3.7 million, respectively

(14) COMMITMENTS AND CONTINGENCIES

Operating Lease Commitments

The Company has certain minimum obligations under non-cancelable operating leases expiring on various dates through 2006 for equipment and facilities. Future annual minimum rental commitments under non-cancelable operating leases at October 31, 2001 are as follows (in thousands):


Fiscal year ending October 31,

2002	$	23,562
2003		20,439
2004		19,852
2005		18,873
2006		16,285
Thereafter		50,346

	$	149,357

Rental expense for fiscal 1999, 2000 and 2001 was approximately $9.5 million, $13.7 million and $19.5 million, respectively.

Litigation

On July 19, 2000, CIENA and CIENA Properties, Inc., a wholly owned subsidiary of CIENA, filed a complaint in the United States District Court for the District of Delaware requesting damages and injunctive relief against Corvis Corporation. The complaint charges Corvis Corporation with infringing several patents relating to CIENA’s optical networking communication systems and technology. On September 8, 2000, Corvis filed an Answer and Counterclaim alleging invalidity, non-infringement and unenforceability of the asserted patents, and tortuous interference with prospective economic advantage. CIENA believes that Corvis’ counterclaims are without merit, and intends to defend itself vigorously. The suit is still in discovery proceedings. The trial of the matter is scheduled to begin on April 1, 2002. On the basis of the proceedings so far, the Company continues to believe they have a strong case on both the claim and counterclaim. Litigation is inherently uncertain, however, and there remains a possibility that CIENA could lose either or both.

On October 3, 2000, Stanford University and Litton Systems filed a complaint in U.S. District Court for the Central District of California alleging that optical fiber amplifiers incorporated into CIENA’s products infringe U.S. Patent No. 4,859,016. CIENA is unable to estimate what impact, if any, an adverse outcome would have on the Company. To date, CIENA has not been served with a complaint in the proceeding. If served, the Company intends to defend the action vigorously.

(15) FOREIGN SALES

The Company has sales and marketing operations outside the United States in Belgium, Brazil, Canada, China, France, Germany, Japan, Korea, Mexico, Spain, Sweden, and the United Kingdom. Included in revenues are export sales of approximately $213.6 million, and $283.1 million and $382.5 million in fiscal years 1999, 2000 and 2001, respectively.

(16) SUBSEQUENT EVENTS

Restructuring Costs

On November 12, 2001, the Company announced an immediate workforce reduction of approximately 380 employees. The workforce reduction was concentrated in the Company’s manufacturing operations staff. Affected employees will be paid through January 10, 2002 and will be eligible for additional severance packages. They will also receive outplacement assistance and training. CIENA will record a restructuring charge of between $5.0 million to $6.0 million, associated with this workforce reduction action, in the first fiscal quarter of 2002
