we see opportunity

GARY B. SMITH

Chief Executive Officer
and Director 

FELLOW SHAREHOLDERS

After a challenging year for the telecommunications
industry, we at CIENA find ourselves in a much different
position than many of our peers and competitors; and
while we do not underestimate the challenges that lie
ahead, we see opportunity.

Industry analysts estimate that service providers’

spending on optical networking equipment fell from nearly
$27 billion in 2000, to $20 billion in 2001, to $9.4 billion in
2002—an unprecedented, market-wide decline. Like others
in the industry, CIENA was affected. Our 2002 revenues
declined from the previous year, and totaled $361 million. 
During the last year, we took difficult steps to adjust

the size of our business to a much different market
environment. However, CIENA’s strong balance sheet
enables us to make decisions that allow us to navigate
to win—not just survive. As a result, we have pursued 
a strategy of balancing continued, strategic investment
in our business with careful financial management and
cost control. We believe achieving this balance will enable
us to capitalize on opportunity.

That opportunity—for us, for our customers and for
their customers—is data. As carriers pursue a growing
enterprise data market, they are faced with the obsoles-
cence of their most valuable assets—their existing voice
networks. Simultaneously, escalating operating costs
remain a significant challenge. CIENA’s vision is to provide
the next-generation hardware and software solutions
that enable carriers to evolve their existing network
infrastructure into data-aware, all-service networks—
enabling new, revenue-generating data services, while at
the same time automating their networks and reducing
operating costs. 

In the meantime, many of our competitors are in the

midst of serious financial challenges. All have gone
through numerous, dramatic restructurings. Some 
have discontinued products or exited product lines 
altogether, and all have significantly reduced their
research and development budgets. As a result, customers
are uncertain—in some cases about the overall financial
viability of vendors and, in others, about the future
direction or delivery of products.

It is this combination—the fit of CIENA’s solutions to
our customers’ business challenges and our competitors’
continuing difficulties—that provides opportunity for
CIENA. Our strong financial position and our commitment
to continued investment are reassuring to customers, 
and the ability of our solutions to solve our customers’ 
business problems—not just their network problems—
differentiates us. 

CIENA’s plan consists of three key elements:
1. Increase our presence with incumbent carriers
Historically, we have not focused our sales and 
marketing efforts on incumbent carriers. However, 
it is clear that these incumbent carriers will be the
industry survivors, and in order for CIENA to be 
successful, we must expand our presence with them.

In recent months, we have targeted these carriers,
and thus far, we are making good progress, securing
business with both AT&T and TELMEX. Unlike our
competitors, from whom we aim to take market
share, these incumbents represent new opportunity
for us. 

2. Expand our product offerings through internal

development and strategic partnerships
We expect that overall carrier spending levels will
remain relatively flat for several years. To grow our
business in this environment, we must expand our
addressable market. Last year, CIENA took several
steps toward this end. In addition to expanding the
feature sets of existing products, we acquired ONI
Systems, which expanded our metropolitan offerings.
We also formed strategic partnerships that further
extend our product offerings. We intend to further
expand our addressable market by:
• Pushing our reach further toward the network
edge to provide a rich set of access services in
data, storage and TDM formats;

• Moving our capabilities up the network hierarchy
so that we can further converge network layers to
achieve additional capex and opex savings; and,
• Uniting all CIENA offerings with our “LightWorks

OS” network operating system for a solution that
enables network-wide discovery and automation
across our entire product portfolio. 

3. Balance strategic investment with prudent 

financial management
We believe success with incumbent carriers and
expansion of our addressable market will speed our
return to profitability, but both require continued
investment in our business. Last year, we took difficult
steps to align our business with a much-changed
market environment, and we will continue to monitor
market dynamics closely and make adjustments 
as required. 

If we successfully strike a balance between investing

toward the opportunities we see and managing our
business in this challenging environment, I believe CIENA
has the potential to grow despite a flat carrier spending
market over the next several years. If so, our success
should be evident in growing revenues, improving
financial performance and returning to profitability.

My sincere thanks to CIENA’s employees who have
worked so hard to give CIENA the opportunity to win.
My thanks also to our customers and shareholders for
their continued belief in and support of our business.

Item 1. Business

General
Overview
CIENA, a leader in intelligent optical networking systems and software, offers telecommunications network
solutions to service providers and enterprises worldwide. Our customers include long-distance carriers, local
exchange carriers, Internet service providers, wireless and wholesale carriers, systems integrators, govern-
ments, and large businesses and non-profit institutions. CIENA offers network solutions that enable service
providers to provision, manage and deliver economic, high-bandwidth services to their customers. In early
2001, the telecommunications industry began a severe decline, which has affected almost all of its segments,
including equipment suppliers like CIENA. That decline, which has continued in 2002, has caused the market
for our equipment to shrink substantially, with a resulting adverse impact on our revenues and profitability.

The Company had revenue of $361 million for its fiscal year ended October 31, 2002, a decrease of more

than 77% when compared with fiscal 2001 revenue of $1,603 million. The Company recorded a net loss of
$1,597 million in fiscal 2002 compared with a net loss of $1,794 million for fiscal 2001.

For the fiscal year ended October 31, 2002, the Company recorded revenue from sales to a total of 
77 customers. This represents an increase of more than 45% over 2001’s customer base of 53. During fiscal
2002, AT&T and Sprint each represented more than 10% of CIENA’s total revenues.

On June 21, 2002, we acquired by merger ONI Systems Corp. (“ONI”), which offered optical transport and
access products for metropolitan networks and enterprises. The addition of ONI’s products to CIENA’s product
portfolio allows CIENA to offer its customers a broader and more comprehensive set of solutions for addressing
the bandwidth and service requirements of their networks and opens up additional market opportunities.

Through fiscal 2001, we derived the majority of our revenue from sales of long-distance optical transport

equipment using dense wave division multiplexing (“DWDM”). In 2001, we began selling our CoreDirector
intelligent optical core switch. During fiscal 2002, our revenues from that product exceeded our revenues from
long-distance transport equipment. Today we believe we hold an industry-leading market share in the important
emerging core switching product category. During fiscal 2002, we also recognized revenue from our metro-
politan optical transport products including the MultiWave Metro product line and the ONLINE products
that we acquired through our merger with ONI and from our multi-service metropolitan access and switching
platform, MetroDirector K2.

In fiscal 2003, CIENA will focus on evolving from an optical networking equipment producer into a strategic
provider of complete network solutions. We intend to increase our presence with incumbent carriers, expand
our addressable market and strike a careful balance between prudent cash management and strategic invest-
ment in the business.

The matters discussed in this section should be read in conjunction with the Consolidated Financial

Statements found under Part II, Item 8 of this annual report on Form 10-K.

Industry Background
Optical Networking
Modern communications systems consist in substantial part of optical networks that transmit digitized voice
and data information over optical fiber using pulses of infrared light. Optical networking technology has
evolved rapidly over the last few years resulting in significant reductions in carriers’ capital and operating
costs. Among other advances, newer technology allows transmission of multiple signals on a single strand of
optical fiber, each signal using a different wavelength of light. This DWDM technology permits optical fibers
to carry more information and reduces the need for carriers to add more fiber to their networks to handle

increased traffic. DWDM technology has been critical to fueling the growth of the global Internet by dramati-
cally reducing the cost to transmit information over long distances and enabling service providers to rapidly
scale their networks to accommodate data traffic demands. More recently, intelligent optical switching
technology has driven down the cost of managing networking equipment based on DWDM technology 
by consolidating and simplifying optical networks. The application of intelligent and distributed software 
to optical switching also has allowed carriers to build more automated networks that can quickly deliver
various telecommunications services to customers without human intervention.

Industry Trends
Deregulation in the United States and privatization in many other countries during the 1990’s began a transition
from a telecommunications 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 facing declining prices for their services with operating expenses growing faster than reve-
nues. 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.

Beginning near the end of 2000, capital markets tightened, leading to a period of uncertainty for service
providers. As access to capital lessened, many service providers curtailed further network build-outs and dra-
matically reduced their overall capital spending. In addition, the industry saw the emergence and general avail-
ability of next-generation optical networking equipment that enabled carriers to spend less and do more. As a
result of increased competition, carriers saw their revenues level off or even decline. The combined effect of
these developments was a sharp decline in the demand for legacy telecommunication equipment and a gen-
eral overall slowdown in carriers’ equipment purchases. As a result, many equipment vendors experienced
financial challenges of their own because of the slowdown and reduced the level of vendor financing they were
able to provide. 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 over-capacity in their networks. Some carriers, with no access to additional capital
and inadequate revenue, failed. Others have declared bankruptcy and are in the process of working through
restructurings leading to uncertainty about their business, their networks and their customers. During this time,
some service providers looked to new products and technologies, in particular optical networking solutions,
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.

Strategy
CIENA is pursuing a strategy of balancing continued investment in our business with prudent cost manage-
ment. We believe that this will better position us for growth as the telecommunications market recovers. We are
currently investing in research and development efforts to expand the features and functionalities of our prod-
ucts and reduce their manufacturing costs. We believe continued innovation is required to deliver networking
solutions that will enable carriers to return to healthy business models by generating more revenues more
quickly for more services. We are also investing in our sales organization and infrastructure in the belief that this
will enable us to gain market share as our competitors wrestle with their own financial and organizational chal-
lenges. While continuing to invest in these areas of our business, we are taking steps to reduce our costs and
operating expenses in an effort to achieve profitability sooner and to preserve our strong cash balance.

•

In implementing the strategy, we are undertaking 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, systems integrators and enterprises.

Broaden the Reach of Our Product Portfolio. In addition to selling to new customers, CIENA intends to
sell more products by expanding our product portfolio through a combination of internal efforts and strate-
gic relationships. Our goal is both to extend our products farther into the edge of the network and to offer
products designed to enable carriers to deliver and sell services beyond simple transport and switching.
Target the Largest Carriers. The nature and relatively small number of customers in our target market
generally require a focused sales effort on a customer-by-customer basis. We plan to devote the bulk
of our sales effort toward the top carriers throughout the world.
Sustain Our Investment in Research and Development. We believe our future success will depend
heavily on our ability to offer products that will allow our customers to reduce their capital expenditures
and operating costs and to address the changing needs of their end-user customers. 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 networking
technology and, where appropriate, make strategic investments or acquisitions designed to help us
maintain our technological leadership.
Prudently Manage Costs and Preserve Our Strong Cash Position. We believe CIENA’s strong cash
balance and low long-term debt significantly differentiates us from our competition. We will continue
to balance strategic investment in our business with our efforts to carefully manage our operating costs
and to preserve our strong cash position.
Pursue Business and Strategic Partnerships. We will pursue cooperative efforts and strategic alliances
with other equipment vendors so as to broaden our product portfolio reach and the breadth of solutions
we can offer our customers. We also are working to develop new sales channels, including relationships
with systems integrators and value-added resellers, to address portions of the enterprise market that we
cannot reach with our own sales force.
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 differ-
entiating factors in our efforts to maintain and enhance our market position.
Reduce Expenses and Increase Flexibility by Outsourcing Manufacturing. CIENA has historically
done much of its manufacturing in-house. Under current market conditions, we believe we can gain effi-
ciencies in manufacturing by outsourcing a larger percentage of manufacturing.
Leverage Our Traffic Management and 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 that the bandwidth and capacity management enabled by next-generation equip-
ment 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. We also believe that carriers want to be able to offer new
and more profitable data services that cannot be offered cost-effectively with currently available equip-
ment. CIENA expects to leverage the core competencies it has developed in the design, development
and deployment of optical networking equipment by pursuing internal product development efforts,
forming strategic alliances and making acquisitions to address these expected opportunities.
Pursue the Opportunity for Solution Sales. As one of the few equipment vendors with a complete next-
generation product portfolio, CIENA is in a position to pursue a “solution sale” approach with carriers.
CIENA plans to offer carriers a choice between an open architecture approach to building networks—
one that combines equipment from multiple vendors, or an integrated solution—one that utilizes only
CIENA equipment. With an integrated CIENA network, service providers will be able to take advantage
of significant capital cost savings. In addition, an integrated CIENA network will offer customers signifi-
cant 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 the ability to offer carriers an inte-
grated solution that delivers significant capital and operational cost savings over other vendors’ solutions
will be a strategic advantage.

CIENA’S Solutions
CIENA’s intelligent networking solutions are designed to enable service providers to transition from inefficient,
legacy, voice-centric networks to more efficient data-friendly, networks. CIENA’s systems address the network
scalability, 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 opera-
tions expenses.
The software functionality of CIENA’s equipment creates a network environment where distributed
intelligence—intelligence at the network element level—takes the place of centralized network intelli-
gence. As a result, CIENA networks can “think” for themselves, making dynamic decisions without
human intervention thereby facilitating provisioning and protection capabilities and lowering associated
operating costs.
CIENA’s equipment is designed to reduce 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.

• With the bandwidth flexibility and availability enabled by CIENA’s optical transport equipment utilizing
DWDM and coarse wave division multiplexing (“CWDM”) 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.
Our optical networking product portfolio is targeted at the critical areas of service provider net-

works: intelligent optical switching, long-distance optical transport, short-distance optical transport and
network management.
•

Intelligent Optical Switching. Our family of intelligent optical core switches, CoreDirector, and 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 using
sophisticated software to incorporate the functionality of multiple network elements into a single net-
work element with previously unavailable switching and bandwidth management capabilities.

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. MetroDirector K2
has been designed to easily integrate into existing network environments and deliver superior levels of
bandwidth optimization, reliability, service flexibility, provisioning capabilities, and support for circuit-
switched and data-centric traffic.

Through alliances with Équipe Communications Corporation (“Équipe”) and WaveSmith Networks, Inc.
(“WaveSmith”), we also offer equipment that enables multi-service switching in both the core and at the
edge of the optical network.

• Optical Transport. CIENA’s long-distance optical transport products, CoreStream, MultiWave Sentry,

MultiWave 1600, and our short-distance products, MultiWave Metro, MultiWave Metro One, and ONLINE
Metro, utilize DWDM technology that enables carriers to add critical network bandwidth cost-effectively
when and where they need it. As a result, service providers are better able to scale their networks to meet
demand. CIENA’s short-distance product, ONLINE Edge, utilizes CWDM technology, enabling delivery
of a comprehensive set of high-bandwidth services to customers’ sites at the optical edge of their metro
networks. CIENA’s ONLINE products utilize the ONWAVE multiplexer cards to combine multiple SONET/SDH
or data signals into an individual wavelength channel. The ONWAVE product family currently includes the
ONWAVE OC-48 SONET/SDH Add/Drop Multiplexer (ADM), ONWAVE OC-192/STM-64 Multiplexer, ESCON
Multiplexer and Data Multiplexer which can be configured for gigabit ethernet or fibre channel services.

• Network Management and Network Design. ON-Center, CIENA’s fully integrated family of software-
based tools for comprehensive element, network and service layer management and network design, is
designed to enable accelerated deployment of new, differentiating optical services. ON-Center is designed
to reduce network operating and management costs.
Services. CIENA offers complete engineering, furnishing and installation services as well as full-time
customer support from strategic locations worldwide.

•

Product Development
We believe that to be successful we must continue to enhance our existing products and develop new prod-
ucts that meet our customers’ needs and maintain our technological competitiveness. As a result, CIENA has
continued to pursue strategic investment in our products and their feature sets despite the downturn in the
communications industry. Research and development expenses (exclusive of stock compensation cost of
$15.7, $17.8 and $0.0 million) were $239.6, $235.8 and $125.4 million for fiscal 2002, 2001 and 2000, respec-
tively. For more information regarding our research and development expenses, see Item 7. “Management’s
Discussion and Analysis of Financial Conditions and Results of Operations.”

We plan to continue to make investments in research and development on enhancements of our existing
products that we believe will enable service providers to increase revenues or improve operating costs, including
adding transport functionality to our switching products, extending the reach of our long-haul products and
enhancing our network management platform. We also have engineering efforts focused on cost reductions
for our products. In addition, we plan to continue to invest in the development of new products, especially
products that operate at the edge of the network and products that enable sophisticated services beyond
transport and switching.

Our product development process is driven by market demand and a close collaboration among our

marketing, sales and product development organizations. We also incorporate feedback from our customers
in the product development process. In addition, we participate in industry and standards organizations where
appropriate and incorporate information from these contacts throughout the product development process.

Marketing and Distribution
CIENA’s intelligent networking solutions require substantial investment. Our target customers in the fiber
optic telecommunications market—where network capacity and reliability are critical—are 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 can lead
to a very long sales cycle for much of our optical networking equipment, often more than a year between
initial introduction to the Company and commitment to purchase. This has led CIENA to pursue sales efforts
on a focused, customer-by-customer basis.

We believe that our long-term success depends significantly on our ability to attract incumbent carriers

as customers. These include the regional Bell operating companies (“RBOCs”) in the United States, the large,
traditional telecommunications operators (“TOs”) in the rest of the world, many of which were formerly gov-
ernment-owned “post, telephone and telegraph” enterprises. In order to become a vendor to these service
providers, we must execute on all the elements of our strategy discussed in this section with the needs of
these carriers in mind. In addition, we must also ensure that our products will function effectively in the estab-
lished networks of these companies.

CIENA has organized its worldwide direct sales activities by four geographical regions: North America,
East; North America, West/Latin America; Europe, Middle East, and Africa; and Asia Pacific. Another segment
of our sales force is dedicated to selling through channels such as systems integrators and resellers. For direct
sales, account teams comprised of an account manager and systems engineer are assigned responsibility for
each customer account. In some countries, CIENA makes use of distributors, independent marketing repre-
sentatives or independent sales consultants. For financial information about geographic areas and a description
of risks attendant to our international operations, see Item 7. “Management’s Discussion and Analysis of
Financial Conditions and Results of Operations.”

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
Prior to fiscal 2002, CIENA did much of the manufacturing of its optical transport products in-house. However,
in response to changing market conditions, we have outsourced a larger percentage of our manufacturing.
CIENA now relies on a small number of contract manufacturers to assemble and test its CoreDirector,
MetroDirector K2, and ONLINE products. We work closely with these suppliers to manage quality, cost and
delivery times. We continue to perform much of the assembly and testing of the CoreStream, MultiWave Sentry,
MultiWave 1600, MultiWave Metro and MultiWave Metro One products, but outsource all of the printed circuit
board assembly and some of the optical assembly and module functional testing. We manufacture in-house
all the in-fiber Bragg gratings used in our optical transport products. All products undergo a final system test
performed by us in our Maryland facility.

CIENA will continue to evaluate the extent to which third party manufacturers can do even more of our

manufacturing on a reliable and cost-effective basis. We believe that this approach has allowed us to:
•
•
•
•

reduce the capital equipment expenditures that would be required for a full manufacturing operation;
reduce our facilities requirements by limiting the amount of space dedicated to manufacturing and operations;
conserve working capital by reducing the amount of inventory we must stock; and
respond to changes in market demand.
We rely on numerous vendors to manufacture and supply the components for our products, including several
high performance components made to our specifications. While we endeavor to minimize the risk of production
interruption by selecting and qualifying alternative vendors for components, some key optical and electronic com-
ponents are currently available from sole or limited sources, and in some cases, that source also is a competitor.

Competition
Competition in the telecommunications equipment industry is intense and has become increasingly so as the
market for optical networking products has declined. 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 multi-national, 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 Alcatel Alsthom Group
(“Alcatel”), Cisco Systems, Inc. (“Cisco”), Fujitsu Group (“Fujitsu”), Hitachi Ltd. (“Hitachi”), Huawei Technologies
Co. Ltd (“Huawei”), Lucent Technologies Inc. (“Lucent”), NEC Corporation (“NEC”), Northern Telecom, Inc.
(“Nortel”), Siemens AG (“Siemens”), and Telefon AB LM Ericsson (“Ericsson”). There are also several smaller,
but established, companies, such as ADVA AG Optical Networking (“ADVA”), Corvis Corporation (“Corvis”),
Sycamore Networks, Inc. (“Sycamore”), and Tellium, Inc. (“Tellium”), that offer one or more products that
compete directly or indirectly with our offerings. In addition, there are a variety of earlier-stage companies
with products targeted at the optical networking market in some stage of development or deployment, most
of them employing advanced technology that could offer advantages over products offered by CIENA.

In addition to optical networking equipment suppliers, traditional TDM-based transmission, SONET multi-

plexing, and digital cross-connect equipment suppliers compete with CIENA in the market for transmission
capacity and switching capabilities. Alcatel, Fujitsu, Hitachi, Lucent, NEC, Nortel, and Tellabs, Inc. (“Tellabs”)
are already providers of a full complement of such transmission and switching equipment.

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. These licenses expire when the last of the licensed patents
expires or is abandoned. We have also utilized publicly available technology associated with Erbium-doped
fiber amplifiers and applied our design, engineering and manufacturing skills to develop our optical transport
and switching systems. CIENA also licenses from third parties certain software components for its network

7

10-K CIENA Corporation

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

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.

We are currently engaged in significant patent lawsuits. See Item 3. “Legal Proceedings.” In addition,
parties who claim that we may be infringing one or more of their patents approach us from time demanding
that we take a license from them. We are currently engaged in discussions with one such company.

Item 2. Properties

As of October 31, 2002, all of CIENA’s properties are leased. CIENA’s principal executive offices are
located in Linthicum, Maryland. We lease nine facilities related to ongoing operations, including the 
five buildings located at various sites near Linthicum, Maryland, one as an engineering facility, three as
manufacturing facilities, and one as an administrative and sales facility. The Company also has engineering
and/or service facilities located in Alpharetta, Georgia; San Jose, California; and Durham, North Carolina.
The Company also leases various small offices in the United States and abroad to support its sales and
installation services.

CIENA leases a number of properties that we no longer occupy. As part of its restructuring costs, CIENA
provides for the estimated cost of the net lease expense for these facilities. The cost is based on the future
minimum lease payments under contractual obligations offset by estimated future sublease payments. As of
October 31, 2002, CIENA’s accrued restructuring liability related to these properties was $87.8 million. If actual
market conditions are less favorable than those projected by management, additional restructuring costs
associated with these facilities may be required. For additional information regarding the Company’s lease
obligations, See Item 8. “Financial Statements and Supplementary Data.”

Item 3. Legal Proceedings

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. The complaint seeks injunctive relief, royalties and damages. CIENA has still not
been served in the case. We are currently engaged in discussions with the plaintiff regarding settlement of
the matter. We are unable to determine whether the litigation or any settlement we may reach will have an
adverse effect on us.

On July 19, 2000, CIENA and CIENA Properties, Inc., a wholly owned subsidiary of CIENA, filed a com-

plaint 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 three 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. On February 7, 2001, CIENA and
CIENA Properties, Inc. filed an amendment to the complaint to add two additional patents relating to CIENA’s
optical networking communications systems and technology. On March 19, 2001, Corvis filed an Answer and
Counterclaim to the amended complaint alleging invalidity, non-infringement and unenforceability of the
newly asserted patents. The discovery phase of the litigation is now completed. The court has postponed the
trial, originally scheduled to begin on April 1, 2002. We anticipate that it will now take place in February 2003.
CIENA believes that Corvis’ counterclaims are without merit, and intends to defend itself vigorously.

On August 19, 2002, Pirelli S.p.A. and certain of its affiliates (“Pirelli”) filed a complaint against us in the
United States District Court for the District of Delaware alleging that we were in breach of our obligation to pay
royalties under a license agreement that was part of the resolution of an earlier series of disputes between us
and Pirelli. We have reached an agreement with Pirelli to resolve the lawsuit. Under the terms of the settlement,
we will pay Pirelli $11.0 million, and Pirelli will forego claims to all other royalties, past or future.

Upon acquiring ONI Systems, we became the defendant in a lawsuit originally brought on March 10, 2000,
against ONI by Nortel Networks in the United States District Court for the Northern District of California. The
suit alleges that ONI Systems’ products infringe a patent held by Nortel Networks, and sets forth allegations
of misappropriation of trade secrets, unlawful business practices and common law unfair competition. Nortel
Networks is seeking preliminary and permanent injunctions and damages in connection with its claims. If it
were to obtain an injunction preventing the sale of the allegedly infringing products, we could lose revenue
or be required to incur expenses to modify the products to avoid infringement. We could also be ordered to
pay damages, which could be substantial. We believe, however, that we have valid defenses to the claims, and
we intend to continue to defend the lawsuit vigorously. Trial in the case is currently scheduled for January 2003.
In addition, on November 27, 2002, Nortel Networks filed a complaint in the United States District Court

for the Eastern District of Texas alleging that additional CIENA products infringe patents held by Nortel
Networks. The complaint seeks injunctive relief, royalties and damages. CIENA has still not been served in the
case. We believe we have good defenses to the complaint, and if Nortel prosecutes it, we intend to defend
the action vigorously. If Nortel Networks were to prevail, however, there is a possibility that we may have to
negotiate a license agreement, pay substantial royalties or modify our products to avoid infringement.

As a result of the merger with ONI, we also became a defendant in two substantially identical purported

class actions on behalf of ONI security holders originally brought against ONI and members of its board of
directors. The complaints allege that the director defendants breached their fiduciary duties to ONI in approv-
ing the merger with CIENA and seek declaratory, injunctive and other relief permitted by equity. The plaintiffs
failed to obtain an injunction against completion of the merger. We believe that these lawsuits are without
merit and will continue to defend them vigorously. The first of these cases was filed on February 20, 2002, in
the Superior Court of the State of California, County of San Mateo, and is encaptioned K.W. Sams, On Behalf
of Himself and All Others Similarly Situated v. ONI Systems Corporation, et al. The second case was brought
on March 19, 2002, in the Superior Court of the State of California, County of Santa Clara, and is encaptioned
Steven Myeary, On Behalf of Himself and All Others Similarly Situated v. ONI Systems Corporation.

As a result of the merger with ONI, we also became a defendant in a securities class action lawsuit.
Beginning in August 2001, a number of substantially identical class action complaints alleging violations of
the federal securities laws were filed in the United States District Court for the Southern District of New York.
These complaints name ONI, Hugh C. Martin, ONI’s former chairman, president and chief executive officer;
Chris A. Davis, ONI’s former executive vice president, chief financial officer and administrative officer; and cer-
tain underwriters of ONI’s initial public offering as defendants. The complaints were consolidated into a single
action, and a consolidated amended complaint was filed on April 24, 2002. The amended complaint alleges,
among other things, that the underwriter defendants violated the securities laws by failing to disclose alleged
compensation arrangements (such as undisclosed commissions or stock stabilization practices) in the initial
public offering’s registration statement and by engaging in manipulative practices to artificially inflate the
price of our common stock after the initial public offering. The amended complaint also alleges that ONI and
the named former officers violated the securities laws on the basis of an alleged failure to disclose the under-
writers’ alleged compensation arrangements and manipulative practices. No specific amount of damages has
been claimed. Similar complaints have been filed against more than 300 other issuers that have had initial
public offerings since 1998, and all of these actions have been included in a single coordinated proceeding.
We intend to defend these actions vigorously.

On May 3, 2002, a shareholder derivative complaint alleging violations of California state law was filed
in the Superior Court of the State of California, County of Santa Clara against ONI. As a result of the merger
with ONI, we have also become a defendant in the lawsuit. The complaint names Hugh Martin; the other
members of ONI’s former board of directors; Terrence J. Schmid, ONI’s former chief financial officer and vice
president, finance and administration; and certain underwriters of ONI’s initial public offering as defendants.
The complaint alleges that the defendants breached their fiduciary duties, acted negligently and were unjustly
enriched in determining the offering price of ONI Systems common stock in ONI’s initial public offering. No
specific amount of damages has been claimed. The complaint is encaptioned Sabrina J. Kurzman and Michael J.
Kurzman, Derivatively on Behalf of ONI Systems Corp. v. Hugh C. Martin. In September 2002, we filed a
motion to dismiss the complaint. Our motion to dismiss was granted by the court on November 6, 2002. On
December 2, 2002, the plaintiffs filed a notice of appeal from the court’s order.

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, a leader in intelligent optical networking systems and software, offers telecommunications network
solutions to service providers and enterprises worldwide. Our customers include long-distance carriers, local
exchange carriers, Internet service providers, wireless and wholesale carriers, systems integrators, governments,
large businesses and non-profit institutions. CIENA offers network solutions that enable service providers to
provision, manage and deliver economic, high-bandwidth services to their customers. In early 2001, the
telecommunications industry began a severe decline, which has affected almost all of its segments, including
equipment suppliers like CIENA. That decline, which has continued in 2002, has caused the market for our
equipment to shrink substantially, with a resulting adverse impact on our revenues and profitability.

For the last several years, the market for our equipment was influenced by the entry of a substantial

number of new companies into the communications services business. In the United States, this was largely
due 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 capital
improvements, causing an acceleration in the growth of the market for telecommunications equipment.

The last two years have 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. More recently, several of the
more established carriers have experienced significant financial distress. These developments have 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, but the economies in virtually all
of the countries we market our products. The combination of these factors has caused our customers to become
more conservative in their capital investment plans and more uncertain about their future purchases. As a conse-
quence, we are facing a market that is both reduced in size and more difficult to predict and plan for.

These trends have had a number of significant effects on our business during fiscal 2002, including the reduc-
tion of revenues by $1,242.0 million compared to fiscal 2001, the incurrence of $286.5 million of costs related to
obsolete inventory and excess purchase commitments, restructuring charges of $225.4 million, goodwill impairment
charges of $557.3 million, provisions for bad debt expense of $14.8 million, $15.7 million in losses on equity invest-
ments and a net income tax charge of approximately $110.7 million to establish a valuation allowance against our
deferred tax assets. Our net loss of $1,597.5 million during fiscal 2002 was primarily attributable to these factors.
On June 21, 2002, we acquired by merger ONI Systems Corp. (“ONI”), a NASDAQ-listed corporation

headquartered in San Jose, California. In anticipation of and following the merger, the two companies took
steps to eliminate functional redundancies and achieve operational cost synergies anticipated as a result of
their combination. During the quarter ended July 31, 2002, CIENA and ONI reduced their combined work-
force by approximately 283 employees. Approximately $3.8 million of costs associated with the ONI workforce
reduction qualify for treatment under EITF 95-3 “Recognition of Liabilities in Connection with a Purchase
Combination” and were recorded as an element of the acquisition.

As of October 31, 2002, CIENA and its subsidiaries employed approximately 2,118 persons, which was 

a net reduction of 1,660 persons from the approximate 3,778 employed on October 31, 2001.

Critical Accounting Policies and Estimates
The preparation of consolidated financial statements requires CIENA to make estimates and judgments that
affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent
assets and liabilities. On an on-going basis, CIENA re-evaluates its estimates, including those related to bad
debts, inventories, investments, intangible assets, goodwill, income taxes, warranty obligations, restructuring,
and contingencies and litigation. CIENA bases its estimates on historical experience and on various other

assumptions that are believed to be reasonable under the circumstances, the results of which form the basis
for making judgments about the carrying values of assets and liabilities that are not readily apparent from
other sources. Actual results may differ from these estimates under different assumptions or conditions. CIENA
believes the following critical accounting policies affect its more significant judgments and estimates used in
the preparation of its consolidated financial statements.

Revenue Recognition
CIENA recognizes product revenue in accordance with the shipping terms specified and where collection is reason-
ably 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 installa-
tion 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 trans-
actions 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.

Allowances for Doubtful Accounts
CIENA maintains allowances for doubtful accounts for estimated losses resulting from the inability of its
customers to make required payments. If the financial condition of CIENA’s customers were to deteriorate,
resulting in an impairment of their ability to make payments, additional allowances may be required. As of
October 31, 2002, our accounts receivable balance, net of allowances for doubtful accounts of $9.5 million,
was $28.7 million, which included three customers who accounted for 19.3%, 15.0%, and 12.8% of the net
trade accounts receivable, respectively.

Warranties
CIENA provides for the estimated cost of product warranties at the time revenue is recognized. CIENA
engages in extensive product quality programs and processes including actively monitoring and evaluating
the quality of its component suppliers and third party contractors. CIENA’s warranty obligation is affected 
by product failure rates and material usage and service delivery costs incurred in correcting a product failure.
Should actual product failure rates, material usage or service delivery costs differ from CIENA’s estimates, revi-
sions to the estimated warranty liability would be required.

Reserve for Inventory Obsolescence
CIENA writes down its inventory for estimated obsolescence or unmarketable inventory equal to the difference
between the cost of inventory and the estimated market value based on assumptions about future demand
and market conditions. As a result of the further decline in capital spending by our customers and a further
decline in forecasted revenues of existing products, we recorded provisions for inventory, including purchase
commitments, of $286.5 million during fiscal 2002. If actual market conditions are less favorable than those
projected by management, additional inventory write-downs may be required.

Restructuring
As part of its restructuring costs, CIENA provides for the estimated cost of the net lease expense for facilities
that are no longer being utilized. The cost is based on the future minimum lease payments under contractual
obligations offset by estimated future sublease payments. As of the end of fiscal 2002, CIENA’s accrued restruc-
turing liability related to net lease expense and other related charges was $87.8 million. If actual market con-
ditions are less favorable than those projected by management, additional restructuring costs associated with
these facilities may be required.

Minority Investments
CIENA holds minority interests in companies having operations or technology in areas within its strategic
focus. As of October 31, 2002, $16.1 million of these investments are included in other long-term assets.
CIENA records an investment impairment charge when it believes an investment has experienced a decline 
in value that is other than temporary. During fiscal 2002, we recorded a charge of $16.6 million from a decline
in the fair value of our equity investments that was determined to be other than temporary. Future adverse
changes in market conditions or poor operating results of underlying investments could result in losses or an
inability to recover the carrying value of the investments that may not be reflected in an investment’s current
carrying value, thereby possibly requiring an impairment charge in the future.

Impairment of Goodwill
CIENA adopted Statement of Financial Accounting Standards No. 142 “Goodwill and Other Intangible Assets”
(SFAS No. 142) effective November 1, 2001 and upon adoption ceased to amortize goodwill. As of October 31,
2002, CIENA’s assets include $212.5 million related to goodwill. SFAS No. 142 requires goodwill amortization
to cease and for goodwill to be tested for impairment on an annual basis and between annual tests if an event
occurs or circumstances change that would more likely than not reduce the fair value of CIENA below its earn-
ings amount. CIENA performed the required annual impairment assessment of goodwill balances in accordance
with the provisions of SFAS No. 142 during the fourth quarter fiscal 2002 which resulted in a goodwill impairment
charge of $557.3 million. If actual market conditions are less favorable than those projected by management
or if an event occurs or circumstances change that would more likely than not reduce the fair value of CIENA
below its earnings amount, additional goodwill impairment charges may be required.

Deferred Tax Valuation Allowance
As of October 31, 2002, CIENA has recorded a valuation allowance of $739.6 million against our gross deferred
tax assets of $739.6 million. The valuation allowance is calculated in accordance with the provisions of Statement
of Financial Accounting Standards No. 109, “Accounting for Income Taxes” (“SFAS 109”) which requires an
assessment of both positive and negative evidence when measuring the need for a valuation allowance. Positive
evidence, such as operating results during the most recent three-year period, is given more weight when, due
to our current lack of visibility, there is a greater degree of uncertainty that the level of future profitability needed
to record the deferred assets will be achieved. Our results over the most recent three-year period were heavily
affected by our recent deliberate and planned business restructuring activities. The Company’s cumulative loss
in the most recent three-year period represents sufficient negative evidence to require a valuation allowance
under the provisions of SFAS 109. The Company intends to maintain a valuation allowance until sufficient positive
evidence exists to support its reversal.

Results of Operations
Fiscal Years Ended 2002, 2001 and 2000
Revenue. We recognized $361.2, $1,603.2, and $858.8 million in revenue for the fiscal years 2002, 2001, and
2000, respectively. The decrease in revenue of $1,242.0 million, or 77.5% from fiscal 2001 to 2002 was due
primarily to the reduction in demand for optical networking products worldwide. This decrease in revenue
occurred even though we had sales to 77 customers in fiscal 2002 as compared to 53 customers in fiscal 2001.
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 across all product lines.

During fiscal 2000 and 2001, we derived the majority of our revenue from sales of long-distance optical

transport equipment using DWDM. In 2001, we began selling our CoreDirector intelligent optical core switch.
During fiscal 2002, our revenues from that product exceeded our revenues from long-distance transport equip-
ment. Today we believe we hold an industry-leading market share in the important emerging core switching
product category. During fiscal 2002, we also recognized revenue from our metropolitan optical transport prod-
ucts including MultiWave Metro and the ONLINE products that we acquired through our merger with ONI and
from our multi-service metropolitan access and switching platform, MetroDirector K2.

Historically, we have relied on a limited number of customers for a substantial portion of our revenue.
During fiscal 2002, Sprint and AT&T each accounted for at least 10% of our revenue and, combined, accounted
for 36.8%. During fiscal 2001, Sprint and Qwest Communications each accounted for at least 10% of our reve-
nue and, combined, accounted for 50.5%. During fiscal 2000, Sprint, Qwest Communications and GTS Network
Ltd. each accounted for at least 10% of our revenue and, combined, accounted for 60.9%. We expect that a
significant portion of our 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 CIENA’s financial condition or operating results. During the following fiscal years,
customers who each accounted for at least 10% of our revenues during the respective periods are as follows

Gross Profit (Loss). Gross profit (loss) was ($234.9), $698.7 and $381.4 million for fiscal 2002, 2001, and

2000, respectively. The $933.6 million decrease in gross profit in fiscal 2002 compared to fiscal 2001 was
the result of decreased revenues and an increase in excess and obsolete inventory charges. As a result of
the further decline in capital spending by our customers and a further decline in forecasted revenues of
existing products, we recorded a provision for inventory, including purchase commitments, of approximately
$286.5 million in fiscal 2002. The $317.3 million increase in gross profit in fiscal 2001 compared to fiscal 2000
was the result of increased revenue.

Gross margin was (65.0%), 43.6% and 44.4% for fiscal 2002, 2001 and 2000, respectively. The decrease in
gross margin from fiscal 2001 compared to fiscal 2002 was largely attributable to increases in inventory obso-
lescence costs, lower manufacturing volumes resulting in reduced manufacturing efficiencies and changes in
product mix resulting in sales of higher proportion of revenue from lower margin installation and tech support
services. The decrease in gross margin from fiscal 2000 to fiscal 2001 was due primarily to an increase in inven-
tory obsolescence costs and price reductions resulting from competitive pressures, which were partially offset
by increased sales of higher margin products such as CoreDirector systems and ON-Center network element
and service management software.

Research and Development Expenses. Research and development expenses (exclusive of stock com-
pensation costs of $15.7, $17.8 and $0.0 million) were $239.6, $235.8 and $125.4 million for fiscal 2002, 2001
and 2000, respectively. The $3.8 million, or 1.6% increase from fiscal 2001 to fiscal 2002 was primarily related
to increases in depreciation expense that were partially offset by reductions in prototype parts and employee
related costs. The $110.4 million, or 88.0% increase from fiscal 2000 to 2001 was related to increases in staffing,
prototype parts and depreciation expenses. During fiscal 2002, 2001 and 2000, research and development
expenses were 66.3%, 14.7% and 14.6% of revenue, respectively. CIENA expects that its research and develop-
ment expenditures will decrease in absolute dollars and as a percentage of revenue during fiscal 2003 due
to its ongoing efforts to align its research and development activities with the current industry environment.
CIENA has expensed research and development costs as incurred.

Selling and Marketing Expenses. Selling and marketing expenses (exclusive of stock compensation of
$3.6, $8.4 and $0.0 million) were $130.3, $146.9 and $90.9 million for fiscal 2002, 2001 and 2000, respectively.
The $16.6 million or 11.3% decrease from fiscal 2002 to 2001 was primarily the result of decreases in staffing
levels, commissions earned, trade show participation and promotional costs. The $56.0 million or 61.6%
increase from fiscal 2000 to 2001 was primarily the result of increases in staffing levels, commissions earned,
depreciation expenses, trade show participation and promotional costs. During fiscal 2002, 2001 and 2000,
selling and marketing expenses were 36.1%, 9.2% and 10.6% of revenue, respectively. We anticipate that our
selling and marketing expenses will decrease in absolute dollars and as a percentage of revenue during fiscal
2003 due to ongoing efforts to align selling and marketing activities with the current industry environment.
General and Administrative Expenses. General and administrative expenses (exclusive of stock com-
pensation of $1.1, $15.2, and $0.0 million) were $50.8, $57.9, and $34.0 million for fiscal 2002, 2001 and 2000,
respectively. The $7.1 million or 12.2% decrease from fiscal 2001 to 2002 was primarily due to decreases in
employee-related costs. The $23.9 million or 70.4% increase from fiscal 2000 to 2001 was primarily the result
of increased staffing levels and outside consulting services. During fiscal 2002, 2001 and 2000 general and
administrative expenses were 14.1%, 3.6% and 4.0% of revenue, respectively. We anticipate that our general
and administrative expenses will decrease in absolute dollars and as a percentage of revenue during fiscal
2003 due to ongoing efforts to align administrative activities with the current industry environment.

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 former 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 $20.3 and $41.4 million
during fiscal 2002 and 2001 respectively. As part of our acquisition of ONI, we recorded deferred stock com-
pensation of $8.8 million relating to the unvested stock options and restricted stock assumed in the acquisition.
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 was $0, $177.8 and $3.2 million for fiscal 2002, 2001
and 2000, respectively. The $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 of $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 acquired from the Cyras purchase was
amortized using a straight-line method based upon a three to seven-year period during fiscal 2001. The
Company adopted SFAS No. 142 effective November 1, 2001 and upon adoption ceased to amortize goodwill.
Amortization of Intangible Assets. Amortization of intangible assets was $9.0, $4.4 and $0.4 million for
fiscal 2002, 2001 and 2000, respectively. The $4.6 million, or 103.3% increase in amortization from 2002 to 2001
is related to our acquisition of ONI, for which we recorded $15.1 million of other intangible assets. The intangible

assets from ONI will be amortized over periods ranging from 2 months to seven years. The $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.

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 esti-
mated value of purchased in-process technology related to Cyras’ 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. During fiscal 2002, we incurred $225.4 million in restructuring charges associated
with our ongoing efforts to align our operations with the current telecommunications industry environment.
The restructuring charge included $32.9 million associated with work force reductions of approximately
1,946 employees, $70.3 million primarily related to lease terminations and non-cancelable lease costs and
an $122.2 million write-down related to property and equipment consisting primarily of leasehold improve-
ments, production equipment and research test equipment.

During fiscal 2001, we recorded a restructuring charge of $15.4 million relating to consolidation of excess
facilities. The consolidation included the closure of certain manufacturing warehouse facilities and the consoli-
dation 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. It is possible that we may incur similar charges in the future as a result of our efforts
to bring costs in line with revenue expectations.

Goodwill Impairment. On adoption of SFAS No. 142, we determined that CIENA’s operations represent
a single reporting unit. We completed an impairment review of the goodwill associated with our reporting unit
during the three months ended January 31, 2002. We compared the fair value of CIENA’s reporting unit at
November 1, 2001 to the carrying value, including goodwill, for the unit at November 1, 2001, and determined
that the carrying value, including goodwill, did not exceed the unit’s fair value. As a result no impairment charge
was required on adoption.

In accordance with SFAS 142, which requires annual testing to determine and measure goodwill impair-
ment on a reporting unit basis, and with the assistance from independent valuation experts, we performed
an assessment of the fair value of CIENA’s single reporting unit and its intangible assets as of September 27,
2002. We compared CIENA’s fair value to its carrying value including goodwill and determined that CIENA’s
carrying value, including goodwill, exceeded fair value. As a result, we then assessed the fair value of CIENA’s
assets, including identified intangible assets, and liabilities and derived an implied fair value for CIENA’s
goodwill. Since the carrying amount of goodwill was greater than its implied fair value, an impairment loss 
of $557.3 million was recognized.

We determined the fair value of CIENA using the average market price of CIENA’s common stock over a
10-day period before and after September 27, 2002 and a control premium of 25%. We determined the esti-
mated fair value of identified intangible assets and non-goodwill intangible assets and liabilities using dis-
counted cash flows. The cash flow periods used were eight years, applying annual growth rates of 10% to
86%. CIENA used discount rates of 10% to 32% based on the specific risks and circumstances associated
with the identified intangible asset or other non-goodwill assets or liability being evaluated. The assump-
tions supporting the estimated cash flows for identified intangible assets and other non-goodwill assets
and liabilities, including the discount rate, reflects management’s estimates. The discount rate was based
upon CIENA’s weighted average cost of capital as adjusted for the risks associated with its operations.

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 connec-
tion with the acquisition of Cyras. We performed the assessment pursuant to Statement Financial Accounting

21

22

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
CIENA’s current operations and expected future sales of MetroDirector K2 as well as the general decline of tech-
nology valuations. The conclusion of that assessment was that the decline in market conditions within CIENA’s
industry was significant and other than temporary. As a result, we 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 was 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 rate 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 CIENA’s
weighted average cost of capital as adjusted for the risks associated with its operations.

Pirelli Litigation. On August 19, 2002, Pirelli S.p.A. and certain of its affiliates (“Pirelli”) filed a complaint
against us in the United States District Court for the District of Delaware alleging that we were in breach of
our obligation to pay royalties under a license agreement that was part of the resolution of an earlier series
of disputes between us and Pirelli. We have reached an agreement with Pirelli to resolve the lawsuit. Under the
terms of the settlement, we will pay Pirelli $11.0 million and Pirelli will forego claims to all other royalties, past
or future. We accounted for the $11.0 million liability by recording an expense of $1.8 million in fiscal 2002
related to the settlement of the litigation, $0.8 million had been reserved for prior to fiscal 2002 and related to
past unpaid royalties, and the remaining $8.4 million was recorded as an intangible asset and will be amortized
over eight years based upon the expected life of the royalty-free technology acquired in the settlement.

Provision for Doubtful Accounts. CIENA performs ongoing credit evaluations of its customers and gen-
erally does not require collateral or other forms of security from its customers. CIENA maintains an allowance
for potential losses when identified. Provision for doubtful accounts expenses were $14.8, ($6.6) and $28.0 mil-
lion for fiscal 2002, 2001 and 2000, respectively. CIENA expected to realize $8.9 million of the gross outstand-
ing accounts receivable balance of $36.9 million due from iaxis Limited as of October 31, 2000. In fiscal 2001,
we received payment for $15.4 million of the gross outstanding accounts receivable balance due from iaxis
Limited primarily through our sales agreement with Dynegy. Accordingly, we recognized a reduction of $6.6 mil-
lion in the provision for doubtful accounts during fiscal 2001. We recorded a provision for doubtful accounts
of approximately $14.8 million during fiscal 2002. This provision related to the estimated losses of $18.1 million
from three customers, each of whom filed for bankruptcy protection during fiscal 2002, offset by $3.3 million
of the gross outstanding accounts receivable balance due from iaxis Limited through our sales agreement
with Dynegy.

Interest and Other Income, Net. Interest income and other income, net were $61.1 million, $63.6 million
and $13.0 million for fiscal 2002, 2001 and 2000, respectively. Interest and other income, net, consists of interest
income earned on our cash, cash equivalents and available-for-sale short and long-term investments.

Interest Expense. Interest expense was $45.3 million, $30.6 million and $0.3 million for fiscal 2002, 2001
and 2000, respectively. The $14.7 million, or 48.2%, increase from fiscal 2001 to fiscal 2002 was attributable
to the acquisition of debt obligations related to ONI. The $30.3 million, or 889.7% increase from fiscal 2000
to fiscal 2001 was primarily attributable to the increase in our debt obligations between the two periods
related to the issuance of CIENA notes.

Loss on Equity Investments, Net. Loss on equity investments, net was $15.7 million for fiscal 2002. We

realized a loss of $1.9 million from the sale of a public equity investment and a loss of $16.6 million from a
decline in the fair value of a certain equity investments that were determined to be other than temporary. On
November 16, 2001, CIENA sold 80.1% of its ownership in ATI International Investments, Inc., the parent com-
pany of ATI Telecom International Ltd. (“Alta”), which resulted in a gain of $2.8 million. CIENA retains a 19.9%
ownership in ATI International Investments, Inc.

Loss on Extinguishment of Debt. During the fourth quarter of fiscal 2002, CIENA purchased, on the
open market, $97.1 million of the $300 million outstanding ONI convertible subordinated notes. On June 21,
2002, CIENA assumed the outstanding ONI 5.00% convertible subordinated notes, in an aggregate principal

amount of $300 million, due October 15, 2005. The ONI convertible subordinated notes were initially recorded
at a value of $218.0 million based upon the present value of the outstanding notes at the time of the acquisition.
We are accreting the difference between the present value of the notes at the time of the acquisition and the
principal value over the remaining period to October 15, 2005, such that the carrying value of the outstanding
notes equals the principal value at the time the notes become due. We paid $75.2 million for notes with a
cumulative accreted book value of $72.5 million at the time of the purchase. The difference in the purchase
price and accreted book value of the notes resulted in a loss on early extinguishment of debt of $2.7 million
for fiscal 2002.

Provision for Income Taxes. CIENA’s income taxes were (7.4)%, (5.1)% and 32.5% of pre-tax earnings

(loss) for fiscal 2002, 2001 and 2000, respectively. The income tax provision for 2002 was $110.7 million. The
Company’s income tax provision for 2002 differed from the expected statutory benefit of 35% primarily due
to the establishment of a valuation allowance against our deferred tax assets and the non-deductibility of
the goodwill impairment. The income tax provision for 2001 differed from the expected 35% benefit primarily
due to the non-deductibility of the goodwill impairment, and in-process research and development. The
income tax provision for 2000 differed from the expected 35% provision primarily due to benefits from research
and development tax credits.

Liquidity and Capital Resources
At October 31, 2002, CIENA’s principal source of liquidity was its cash and cash equivalents, and short-term
and long-term investments. The Company had $377.2 million in cash and cash equivalents, and $1,701.3 million
short-term and long-term investments.

CIENA’s operating activities consumed $25.5 million net cash during fiscal 2002 and provided net cash of
$163.2 million and $59.0 million for fiscal 2001, and 2000, respectively. Cash used in operating activities during
fiscal 2002 was primarily attributable to CIENA’s net loss, offset by non-cash charges related to goodwill impair-
ment, amortization of other intangibles, deferred stock compensation and debt issuance costs, non-cash
portion of restructuring charges, depreciation expense, provision for inventory excess and obsolescence,
decrease in deferred income tax asset and decrease in accounts receivable.

Cash provided by investment activities in fiscal 2002 was $236.6 million. Cash used in investment activities

in fiscal 2001 and 2000 was $1,490.6 million and $103.2 million, respectively. Investment activities included
the net redemption of $26.0 million and $23.8 million of short and long-term investments during 2002 and
2000 respectively and the net purchase of $1,293.2 million of short and long-term investments during 2001.
Investment activities also include approximately $10.0 million, $13.0 million and $3.0 million of equity invest-
ments in private companies during fiscal 2002, 2001 and 2000, respectively. Also included in investment
activities were additions to capital equipment and leasehold improvements in fiscal 2002, 2001 and 2000 of
$66.3 million, $238.5 million and $123.9 million, respectively. The capital equipment expenditures were primarily
for test, manufacturing equipment, computer equipment and leasehold improvements. In fiscal 2002, CIENA
acquired cash of $286.9 million net of expenditures in connection with its acquisition of ONI. The Company
expects additional combined capital equipment and leasehold improvement expenditures of approximately
$48.5 million to be made during fiscal 2003. These capital expenditures will be used to support selling and
marketing, manufacturing and product development activities and the construction of leasehold improvements
for our facilities. We will use our cash and cash equivalents to fund these purchases.

Cash used in financing activities was $231.8 million during fiscal 2002. During fiscal 2001 and 2000, cash

generated from financing activities was $1,582.2 million, and $43.9 million, respectively. The primary use of
cash for financing activities during fiscal 2002 related to the redemption of all outstanding Cyras Systems LLC
4.5% convertible subordinated notes for $178.4 million and the purchase of ONI 5.0% convertible subordinated
notes with a cumulative accreted book value of $72.5 million. Also during fiscal 2002, we received $15.1 mil-
lion from the exercise of stock options and the sale of stock through our employee stock purchase plan and
$5.0 million from the repayment of notes receivable from stockholders. 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 and $4.6 million for the repayment of notes receivable from stockholders. On February 9, 2001, we com-
pleted a public offering of 11,000,000 shares of common stock at a price of $83.50 per share less underwriters’

23

10-K CIENA Corporation

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.

On December 12, 2002, CIENA filed with the U.S. Securities and Exchange Commission a Tender Offer

Statement on Schedule TO (the “Schedule TO”), relating to an offer by CIENA to purchase the remaining
outstanding $202.9 million ONI 5.0% convertible subordinated notes. CIENA’s purpose in seeking to repurchase
the notes is to reduce its annual interest expense and eliminate the need to repay or refinance the debt at
maturity in 2005. The tender offer is not contingent on financing. The notes are convertible into CIENA com-
mon stock at a conversion rate of approximately 7.7525 shares per $1,000 principal amount held, subject to
adjustment. The purchase price for the notes will be $860 in cash per $1,000 principal amount, plus accrued
and unpaid interest up to but not including, the date of payment. If CIENA succeeds in purchasing all of the
outstanding ONI notes at $860 in cash per $1,000 principal amount, plus accrued and unpaid interest, CIENA
will record a loss of $18.7 million related to the extinguishment of the ONI convertible subordinated notes.
The loss is due to the fact that the accreted value of the note is less than the purchase price. We will use our
cash and cash equivalents, and short-term investments to fund the note purchase.

CIENA does not engage in any off-balance sheet financing arrangements. In particular, we do not have

any interest in so-called limited purpose entities, which include special purpose entities (SPEs) and structured
finance entities.

Based on past performance and current expectations, we believe that our cash and cash equivalents,
short-term investments, and cash generated from operations will satisfy our working capital needs, capital
expenditures, investment requirements, ONI note purchase, commitments (see Note 15 to the Consolidated
Financial Statements), and other liquidity requirements associated with our existing operations through at
least the next 12 months.

Effects of Recent Accounting Pronouncements
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 obli-
gations in the period in which they are incurred, which typically could be upon completion or shortly there-
after. The FASB decided to limit the scope to legal obligation and the liability will be recorded at fair value.
We believe the adoption of this standard will not have a material effect on the consolidated financial statements.
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”. We believe the adoption of this standard will not
have a material effect on the consolidated financial statements.

In April 2002, the Financial Accounting Standards Board issued Statement of Financial Accounting Standard

No. 145, “Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No. 13, and
Technical Corrections” (SFAS 145). SFAS 145 clarifies guidance related to the reporting of gains and losses
from extinguishment of debt and resolves inconsistencies related to the required accounting treatment of
certain lease modifications. SFAS 145 is effective for financial statements issued for fiscal years beginning
after May 15, 2002. We believe the adoption of this standard will not have a material effect on the consolidated
financial statements.

In June 2002, the Financial Accounting Standards Board issued Statement of Financial Accounting Standard
No. 146, “Accounting for Costs Associated with Exit or Disposal Activities” (SFAS No. 146). SFAS 146 nullifies
previous guidance on accounting for costs associated with exit or disposal activities and requires a liability
for these costs to be recognized and measured at its fair value in the period in which the liability is incurred.
SFAS 146 is effective for exit or disposal activities initiated after December 31, 2002. We believe the adoption
of this standard will not have a material effect on the consolidated financial statements.

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 Could Continue to Be Adversely Affected by Unfavorable and Uncertain Conditions in the
Communications Industry and the Economy in General
Over the last two years, there has been a sharp contraction of the availability of capital to finance communi-
cations networks, and many of our customers and potential customers have experienced significant financial
distress. This industry trend has been compounded by the slowing not only of the United States economy but
the economies in virtually all of the countries in which we are marketing our products. These developments
have caused a substantial reduction in demand for our products which has adversely affected our revenues
and operating results. In addition, most of our customers have become more conservative and uncertain
about their future purchases which has made managing our business difficult.

We expect the factors described above to continue to affect our business for an indeterminate period,

in several significant ways:
our markets will be characterized by reduced capital expenditures by our customers;
•
•
we will continue to have only limited ability to forecast the volume and product mix of our sales;
• managing our expenditures will be difficult in light of the uncertainties surrounding our business;

28

10-K CIENA Corporation

•

•

•

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 will enable 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 bankruptcies or weakened financial condition of some of our customers may require us to write off
amounts due us from prior sales.
The result of any one or a combination of these factors could lead to further reduced revenues and

increased operating losses.

We Face Intense Competition That 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, Fujitsu, Hitachi, Lucent,
NEC, Nortel, Siemens and Ericsson, have historically dominated the telecommunications equipment industry.
They all have greater financial, marketing, manufacturing and intellectual property resources than CIENA. 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 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.
In addition, several of our largest competitors are experiencing financial difficulties. In competition with
these vendors for the business of customers to which the competitor has been historically a major supplier,
we have confronted situations in which the competitor contends that unless the customer awards it the busi-
ness, the competitor may fail, leaving the customer without support for the competitor’s equipment already
in the network. To the extent that such arguments are successful, we may be at a disadvantage in winning
new business.

Tactics such as those described above can be particularly effective in a highly concentrated customer
base like 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 impor-
tant factor in customer decisions. This 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 reduc-
tion 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 continue to emerge to compete with our products. They often base their products on
the latest available technology. They may achieve commercial availability of their products more quickly due
to the narrower focus of their efforts. Our inability to compete successfully against these companies would
harm our business, financial condition and results of operations.

Economic Conditions May Require Us to Reduce the Size of Our Business Further
In November 2001, February 2002, March 2002, June 2002 (in connection with the ONI merger) and again in
September 2002, we undertook significant reductions in force, some of which were accompanied by dispositions
of assets, as part of our effort to reduce the size of our operations to better match the reduced sales of our
products and services. Weakness in the global economy generally and the telecommunications equipment
market in particular continue to affect our business substantially. We may be required to undertake further
reductions in force. Any such steps would likely result in significant charges from write-downs or write-offs of
assets, costs of lease terminations, and expenses resulting from the termination of personnel.

Product Performance Problems Could Limit Our Sales Prospects
The development and production of new products with high technology content, including optical networking
products, often involves problems with software, components and manufacturing methods. If significant relia-
bility, quality or network monitoring problems develop, including those due to defects in software or faulty
components, a number of negative effects on our business could result, including:
•
•
•
•
•
•
•
•

costs associated with fixing software defects or reworking our manufacturing processes;
high service and warranty expenses;
payment of liquidated damages for performance failures;
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 cause us to
lose customers or otherwise harm our business.

29

10-K CIENA Corporation

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;

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:
•
•
•
•
•
•
•
•
• 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.

30

10-K CIENA Corporation

Our intelligent optical networking products require large investments. We have a limited number of poten-
tial 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 and market conditions have made it more difficult to make reliable estimates of future
revenues. Fluctuations in our revenue can lead to even greater fluctuations in our operating profits. Our bud-
geted expense levels depend in part 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 pur-
chases. 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, our levels of inventory, operating expenses and general
overhead would be high relative to our revenue, reducing our profitability, and perhaps resulting in additional
operating losses.

Our Future Success Will Depend on Our Ability to Acquire New Customers and Expand Our Product Portfolio
Historically, a large percentage of our sales have been made to emerging carriers, many of which have
recently experienced 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 lengthy sales cycles. Many
have long-standing supplier relationships with other vendors, and our experience in selling to them is limited.
These customers often require extensive testing of 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. If we do not succeed 
in penetrating this segment of the market, our business could suffer.

We sell some of our products to systems integrators and, to a limited extent, directly to large enterprises.

We have limited experience with sales through business partners, and it is uncertain to what extent we will
be successful in pursuing them.

In order to make our offerings more attractive both to our existing customers and the new customers we
hope to attract, we believe it is important that we expand our portfolio to include more products that operate
at the edge of the network and add products that enable sophisticated services beyond transport and switching.
We plan to implement this strategy through a combination of internal development, acquisition of smaller
companies, and forming strategic alliances with other vendors. If we fail to execute this strategy, our address-
able market may not be large enough to enable us to reach profitability at our current size.

The Success of Our Strategy Depends on Our Ability to Increase Our Revenue Substantially
We believe that, as a matter of strategy, we must maintain a size and breadth of product portfolio that enables
us to be successful in selling to the largest communications providers. In order to carry out that strategy, we
have deliberately chosen to continue to spend on research and development, sales, and other operating
expenses at levels that will not permit us to return to profitability unless we can increase our revenues sub-
stantially. If we fail to do so, we will be required to modify our strategy, which would likely have an adverse
effect on our financial condition.

We May Not Be Successful in Enhancing and Upgrading Our Products
The market for optical networking products is characterized by rapid technological change, frequent introduc-
tions 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. Failure to keep pace with technological advances would impair the
competitiveness of our products and sooner or later do serious harm to our business.

Our products are based on complex technology that could result in unanticipated delays in developing,
improving, manufacturing or deploying them. Modifying our products to enable customers to integrate them
into a new type of network architecture entails similar development risks.

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
CoreDirector product line over the life of the product and we expect to continue to enhance features of our
CoreStream, ONLINE, and 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
CoreDirector, ONLINE, and MetroDirector K2 product lines; and schedule delays are common in the final vali-
dation 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.

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 uncollectible 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 mate-
rial 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 develop-
ment 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 amortiza-
tion expenses related to intangible assets. In the fourth quarter fiscal 2001 and fourth quarter fiscal 2002, we
incurred a significant write-off of goodwill associated with our previous acquisitions. 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.

31

10-K CIENA Corporation

32

10-K CIENA Corporation

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.

We Face Risks in Reselling the Products of Other Companies
We have recently entered into agreements that permit us to distribute the products of Équipe and WaveSmith.
To the extent we succeed in reselling their products, or products of other vendors with which we may enter
into similar arrangements, we may be required by customers to assume warranty and service obligations.
While these suppliers have agreed to support us with respect to those obligations, they are relatively small
companies with limited financial resources. If they should be unable, for any reason, to provide the required
support, we may have to expend our own resources on doing so. This risk is amplified by the fact that the
equipment has been designed and manufactured by others, and is thus subject to warranty claims whose
magnitude we are currently unable to fully evaluate.

We May Not Be Successful in Selling Our Products through New Channels
Our direct sales force is not designed or equipped to enable us to sell into the enterprise or government mar-
kets, or certain geographic markets. We are accordingly taking steps to develop new sales channels through
distributors and systems integrators for sales of those of our products, particularly the ONLINE Edge, that are
suitable for those markets. We have limited experience in developing and managing such channels, and it is
possible that our efforts may not succeed according to plan, which could reduce our revenues and profitability.

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 compo-
nents 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.

Furthermore, one of our suppliers has recently announced its intention to exit the market for optical com-

ponents. This, or similar decisions by other suppliers, could result in reduced competition and higher prices
for components we purchase. In addition, the loss of a source of supply of key components could require us
to re-engineer products that use those components, which would increase our costs.

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 busi-
ness. 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 perform the majority of the manufacturing opera-
tions for our 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 some 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. If we underestimate our future product requirements, the contract manufacturers

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 man-
ufacturers and forecast future demand, or if they fail to deliver products or components on time, our busi-
ness 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. We buy components from Alcatel, NEC, Nortel, and Siemens. Each of these
companies offers optical communications systems and equipment that compete against 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 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 have filed an intellectual prop-
erty lawsuit to enforce our intellectual property right, and may become involved with additional disputes in
the future. Such lawsuits can be costly and may significantly divert the time and attention of our personnel.
We have received, and may receive in the future, notices from holders of patents in the optical technol-
ogy 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 intellectual property disputes
regarding the possible infringement of our products. In the past, we have been forced to take a license from
the owner of allegedly 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.

We are a defendant in a lawsuit originally brought by Nortel Networks against ONI accusing ONI of
patent infringement and theft of trade secrets. Nortel has also recently filed a separate action against us
alleging that CIENA is infringing several Nortel patents. If Nortel were to win either of these lawsuits, there
is a possibility that we could be required to pay Nortel substantial damages, to negotiate a license agreement
that would require us to pay substantial royalties, or both.

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 inter-
national 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. In some countries, our success will depend in part on our ability to form relationships with local
partners. We cannot be sure that we will be able to identify appropriate partners or reach mutually satisfac-
tory arrangements with them for sales of our products. There is a risk that we may sometimes choose the
wrong partner. For these reasons, we may not be able to maintain or increase international market demand
for our products.

33

10-K CIENA Corporation

34

10-K CIENA Corporation

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.

The Market for Our Long-Haul Product Line Has Substantially Diminished
Our business was originally built on the success of our “long-haul” optical transmission products, Sentry and
CoreStream, which allowed multiple optical signals to be combined for transmission from point to point over
a single optical fiber. During the last several years, carriers around the world, both incumbents and challengers,
have laid and “lit” with optical equipment like ours, a substantial amount of long-haul optical fiber. This has
created what appears to be an oversupply of new communications “bandwidth” on many long-haul routes.
In addition, since the introduction of these products, technological advances have enabled the transmission
of more optical signals over greater distances for less cost. As a consequence, the market opportunity for
long-haul optical equipment, including ours, has declined steeply, dramatically reducing our revenues from
these products. We do not know when, if ever, the market for our long-haul products will return.

Our Stock Price Is Volatile
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 divergence between our actual or anticipated financial results and pub-
lished 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 announce-

ments 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 con-
tinue 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 expecta-
tions, contain projections of results of operations or financial condition or state other “forward-looking” infor-
mation. 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, 2002, the fair value of the portfolio would decline by approximately $134.3 million.

Foreign Currency Exchange Risk. As a global concern, the Company faces exposure to adverse move-

ments 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, 2002, 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 opera-
tions, of cash flows and of changes in stockholders’ equity present fairly, in all material respects, the financial posi-
tion of CIENA Corporation and its subsidiaries at October 31, 2002 and 2001, and the results of their operations
and their cash flows for each of the three years in the period ended October 31, 2002 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

CIENA Corporation
Notes to Consolidated Financial Statements

(1) The Company and Significant Accounting Policies and Estimates
Description of Business
CIENA, a leader in intelligent optical networking systems and software, offers telecommunications network
solutions to service providers and enterprises worldwide. CIENA’s customers include long-distance carriers,
local exchange carriers, Internet service providers, wireless and wholesale carriers, systems integrators, 
governments, and large businesses and non-profit institutions. CIENA offers network solutions that enable
service providers to provision, manage and deliver economic, high-bandwidth services to their customers. 
In early 2001, the telecommunications industry began a severe decline, which has affected almost all of its
segments, including equipment suppliers like CIENA. That decline, which has continued in 2002, has caused
the market for CIENA’s equipment to shrink substantially, with a resulting adverse impact on CIENA’s revenues
and profitability.

Principles of Consolidation
CIENA has 24 wholly owned U.S. and international subsidiaries, which have been consolidated in the accom-
panying financial statements. On June 21, 2002, CIENA acquired all of the outstanding capital stock, and
assumed the options of ONI Systems Corp. (“ONI”), a NASDAQ-listed corporation headquartered in San
Jose, California. 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. Both of these
transactions constituted a tax-free reorganization and were recorded using the purchase accounting method.
The accompanying consolidated financial statements include the accounts of CIENA 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 2, 2002, November 3, 2001, and October 28, 2000). For purposes of financial state-
ment presentation, each fiscal year is described as having ended on October 31. Fiscal 2001 was comprised
of 53 weeks. Fiscal 2002 and 2000 were comprised of 52 weeks.

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 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.

CIENA also has certain other minority equity investments in non-publicly traded companies. These invest-

ments 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, 2001 and October 31, 2002,

41

10-K CIENA Corporation

42

10-K CIENA Corporation

$16.1 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 some or all of these companies. CIENA monitors these
investments for impairment and makes appropriate reductions in carrying values when necessary. During fis-
cal 2002, CIENA recorded a charge of $16.6 million from a decline in the fair values of certain equity invest-
ments that were determined to be other than temporary. 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 serv-
ices and purchased software license costs, are capitalized and amortized over the estimated useful life of
the asset.

Goodwill and Purchased Intangible Assets—Adoption of Statement 142
The Company has recorded goodwill and purchased intangible assets from several acquisitions. See Note 2.
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 purchased intangible assets
to determine if there has been an impairment to their carrying value. Impairments of 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”).

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 state-
ment 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
adopted the provisions of this standard for its first quarter of fiscal 2002.

The following table presents the impact of SFAS 142 on net income (loss) and net income (loss) per share

had SFAS 142 been in effect for the fiscal years 2000, 2001 and 2002 (in thousands):

Concentrations
Substantially all of CIENA’s cash and cash equivalents, short-term and long-term investments, are custodied
at four major U.S. financial institutions. The majority of CIENA’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, CIENA has relied on a limited number of customers for a substantial portion of the Company’s
revenue. During fiscal 2002, Sprint and AT&T each accounted for at least 10% of CIENA’s revenue and combined
accounted for 36.8%. During fiscal 2001, Sprint and Qwest Communications each accounted for at least 10% of
CIENA’s revenue and, combined, accounted for 50.5%. During fiscal 2000, Sprint, Qwest Communications and
GTS Network Ltd. each accounted for at least 10% of CIENA’s revenue and, combined, accounted for 60.9%.
CIENA expects that a significant portion of the Company’s 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 CIENA’s financial condition or operating results.

Additionally, CIENA’s access to certain raw materials is dependent upon single and sole source suppliers.

The inability of any supplier to fulfill supply requirements of CIENA could affect future results. CIENA relies
on a small number of contract manufacturers to perform the majority of the manufacturing operations for its
products. If CIENA cannot effectively manage these manufacturers and forecast future demand, or if they fail
to deliver products or components on time, CIENA’s business may suffer.

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 installa-
tion 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 defer-
ral 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 reve-
nue 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 attrib-
utable 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 invest-
ments, 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 sub-
sidiaries 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 2000, 2001 and 2002 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 state-
ment 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 11.

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 develop-
ment 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 meas-
urement 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 14.

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 oper-
ating 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. See Note 16.

Newly Issued Accounting Standards
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 Company
believes the adoption of this standard will not have a material effect on the consolidated financial statements.

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 Company believes the adoption of this standard
will not have a material effect on the consolidated financial statements.

In April 2002, the Financial Accounting Standards Board issued Statement of Financial Accounting Standard

No. 145, “Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No. 13, and
Technical Corrections” (SFAS 145). SFAS 145 clarifies guidance related to the reporting of gains and losses
from extinguishment of debt and resolves inconsistencies related to the required accounting treatment of
certain lease modifications. SFAS 145 is effective for financial statements issued for fiscal years beginning
after May 15, 2002. The Company believes the adoption of this standard will not have a material effect on
the consolidated financial statements.

10-K CIENA Corporation

In June 2002, the Financial Accounting Standards Board issued Statement of Financial Accounting
Standard No. 146, “Accounting for Costs Associated with Exit or Disposal Activities” (SFAS No. 146). SFAS 146
nullifies previous guidance on accounting for costs associated with exit or disposal activities and requires a
liability for these costs to be recognized and measured at its fair value in the period in which the liability is
incurred. SFAS 146 is effective for exit or disposal activities initiated after December 31, 2002. The Company
believes the adoption of this standard will not have a material effect on the consolidated financial statements.

Reclassification
Certain prior year amounts have been reclassified to conform to current year consolidated financial state-
ment presentation.

(2) Business Combinations
ONI Systems
On February 18, 2002, CIENA announced that it had entered into an agreement to acquire by merger ONI
Systems Corp. (“ONI”), a NASDAQ-listed corporation headquartered in San Jose, California. ONI is a provider
of optical networking equipment specifically designed to address bandwidth and service limitations of regional
and metropolitan networks. Under the terms of the agreement, each outstanding share of capital stock of ONI
was exchanged for 0.7104 shares of CIENA common stock, and CIENA assumed all ONI outstanding options
and warrants as well as the ONI outstanding convertible debt. The acquisition was consummated on June 21,
2002. The stockholders of ONI received 101,120,724 shares of CIENA common stock of which 1,039,429 are
restricted and subject to repurchase.

Additionally, CIENA converted approximately 18,193,345 ONI options and warrants into 12,924,552

options and warrants to purchase CIENA common stock. The aggregate purchase price was $978.2 million,
including CIENA common stock valued at $875.7 million, CIENA options, warrants and restricted stock valued
at $89.2 million and transaction costs of $13.3 million. In determining the purchase price, CIENA used an esti-
mated value of CIENA common stock of approximately $8.75 per share based on the average closing price
of CIENA’s common stock for the two trading days before the February 18, 2002 announcement and the two
trading days after the announcement.

No amount of the purchase price was assigned to in-process research and development. In-process

research and development is purchased in-process technology that, as of the date of the acquisition, had not
reached technological feasibility and had no alternative future use. Based on valuation assessments, the value
of these projects was determined by estimating the resulting net cash flows from the sale of the products

resulting from the completion of the projects, reduced by the portion of the revenue attributable to developed
technology and the percentage of completion of the project. The resulting cash flows were then discounted
back to their present values at appropriate discount rates.

The $13.0 million assigned to the value of existing technology represents purchased technology for which
development had been completed as of the date of acquisition. This amount was determined using the income
approach. This method consisted of estimating future net cash flows attributable to existing technology for a
discrete projection period and discounting the net cash flows to their present value. The existing technology
will be amortized over a seven-year period. The $2.1 million assigned to the other intangible assets, non-
compete agreements and contracts, will be amortized over a range of two months to one year.

During the quarter ended July 31, 2002, CIENA and ONI reduced their combined workforce by approxi-

mately 283 employees. Approximately $3.8 million of costs associated with the ONI workforce reduction qual-
ify for treatment under EITF 95-3 “Recognition of Liabilities in Connection with a Purchase Combination” and
were recorded as an element of the acquisition.

The $80.2 million assigned to the value of the unfavorable lease commitments was based upon the
present value of the assumed lease obligations based upon current rental rates at the time of the acquisition.
These unfavorable lease commitments will be paid over the respective lease terms through fiscal 2011. The
$218.0 million assigned to the value of the ONI $300.0 million principal amount of 5.0% convertible subordi-
nated notes due October 15, 2005 was based upon the present value of the notes at the time of the acquisition.
CIENA is accreting the difference between the present value of the notes and the outstanding principal value
over the remaining period to October 15, 2005, such that the carrying value of the notes equals the principal
value at the time the notes become due.

The amount of goodwill allocated to the purchase price was $590.9 million and is not deductible for tax
purposes. The Company operates in one operating segment and reports only certain enterprise-wide disclo-
sures. Accordingly, the goodwill from this transaction is not part of a reportable segment.

The following unaudited pro forma data summarizes the results of operations for the period indicated as
if the ONI 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 June 21, 2002 acquisition, adjusted to include
the pro forma effect of amortization of intangibles, deferred stock compensation costs, and the tax effects
to the pro forma adjustments. 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.)

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’ convertible subordinated indebtedness.
The Cyras K2 product, which has become CIENA’s MetroDirector K2, enables carriers of metropolitan area
networks to consolidate multiple legacy network elements into a single switching platform.

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 pur-
chased in-process technology related to Cyras’ K2 product development that had not yet reached techno-
logical 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 attrib-
utable to existing K2 technology for a discrete projection period and discounting the net cash flows back to
their present value.

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

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

(3) Restructuring Costs and Impairment Charges
Restructuring
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 cer-
tain 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.

On November 12, 2001, the Company announced a workforce reduction of approximately 380 employees
concentrated in manufacturing operations staff. The Company recorded a restructuring charge of $6.8 million
associated with this action in the first quarter of fiscal 2002.

On February 5, 2002, CIENA announced a workforce reduction of approximately 400 employees largely
concentrated in manufacturing operations and research and development activities associated with the clo-
sure of CIENA’s Marlborough, Massachusetts research and development facility. On March 26, 2002, CIENA
announced a company-wide workforce reduction of approximately 650 employees. CIENA recorded a restruc-
turing charge of $121.4 million associated with the workforce reductions, lease terminations, non-cancelable
lease costs and the write-down of certain property, equipment and leasehold improvements associated with
this action in the second quarter of fiscal 2002.

During the third quarter of fiscal 2002, CIENA and ONI reduced their combined workforce by approximately

283 employees. Approximately $3.8 million of costs associated with the ONI workforce reduction qualify for
treatment under EITF 95-3 “Recognition of Liabilities in Connection with a Purchase Combination” and were
recorded as an element of the acquisition. As a result of these integration and restructuring activities, CIENA
recorded a charge of $11.0 million during the quarter ended July 31, 2002 associated with workforce reductions
of approximately 66 employees, lease terminations, non-cancelable lease costs and the write-down of certain
property, equipment and leasehold improvements. Also during the quarter ended July 31, 2002, the Company
recorded an additional restructuring charge of approximately $7.6 million to increase the estimated cost of
the net lease expense for previously restructured facilities.

On September 20, 2002, CIENA announced a company-wide workforce reduction of approximately
450 employees. The Company recorded a restructuring charge of $78.7 million associated with the workforce
reductions, lease terminations, non-cancelable lease costs and the write-down of certain property, equipment
and leasehold improvements associated with this action in the fourth quarter of fiscal 2002.

During the twelve months ended October 31, 2002, approximately 1,946 CIENA employees were termi-

nated. The remaining balance of the charges associated with the workforce reductions will be paid by the
second quarter of fiscal 2003.

Since the fourth quarter of fiscal 2001, the Company has recorded a net charge of $122.2 million related

to the write-down and disposal of certain property, equipment and leasehold improvements. These assets are
being carried at their fair market value less selling and disposal costs. The remaining facilities balance is related
to the net lease expense. This will be paid over the respective lease terms through fiscal 2019.

Impairment Charges
The Company adopted SFAS No. 142 effective November 1, 2001 and upon adoption ceased to amortize
goodwill. On adoption of SFAS No. 142, the Company determined that its operations represent a single
reporting unit. The Company completed an impairment review of the goodwill associated with its reporting
unit during the three months ended January 31, 2002. The Company compared the fair value of its reporting
unit at November 1, 2001 to the carrying value including goodwill for the unit at November 1, 2001, and
determined that the carrying value, including goodwill, did not exceed the unit’s fair value. As a result, no
impairment charge was required on adoption.

In accordance with SFAS 142, which requires annual testing to determine and measure goodwill impair-

ment on a reporting unit basis, and with the assistance from independent valuation experts management
performed an assessment of the fair value of the Company’s single reporting unit and its intangible assets
as of September 30, 2002. The Company compared its fair value to its carrying value including goodwill and
determined that its carrying value, including goodwill, exceeded fair value. As a result, the Company then
assessed the fair value of its assets, including identified intangible assets, and liabilities and derived an implied
fair value for its goodwill. Since the carrying amount of goodwill was greater than its implied fair value, an
impairment loss of $557.3 million was recognized.

The fair value of the Company was determined using the average market price of the Company’s common
stock over a 10-day period before and after September 27, 2002 and a control premium of 25%. The Company
determined the estimated fair value of identified intangible assets and non-goodwill intangible assets and
liabilities using discounted cash flows. The cash flow periods used were eight years, applying annual growth
rates of 10% to 86%. The Company used discount rates of 10% to 32% based on the specific risks and circum-
stances associated with the identified intangible asset or other non-goodwill assets or liability being evaluated.
The assumptions supporting the estimated cash flows for identified intangible assets and other non-goodwill
assets and liabilities, including the discount rate, reflects management’s estimates. The discount rate was based
upon the Company’s weighted average cost of capital as adjusted for the risks associated with its operations.
The changes in the carrying amount of goodwill for the fiscal year 2002 are as follows (in thousands):

Balance as of November 1, 2001

As part of CIENA’s review of financial results for fiscal 2001, CIENA performed an assessment of the carry-

ing value of the Company’s 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 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 ter-
minal 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 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.

(5) Accounts Receivable
As of October 31, 2002, the trade accounts receivable included three customers who each accounted for
19.3%, 15.0%, and 12.8% of the trade accounts receivable, respectively. 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.

CIENA performs ongoing credit evaluations of its customers and generally has not required collateral
or other forms of security 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, 2002 and October 31, 2001
was $9.5 million and $1.5 million, respectively. CIENA expected to realize approximately $8.9 million of the
gross outstanding accounts receivable balance of $36.9 million due from iaxis Limited as of October 31, 2000.
In fiscal 2001, CIENA received payment for approximately $15.4 million of the gross outstanding accounts
receivable balance due from iaxis Limited primarily through the Company’s sales agreement with Dynegy.
Accordingly, CIENA recognized a reduction in the provision for doubtful accounts of $6.6 million during fiscal
year 2001. CIENA recorded a provision for doubtful accounts of approximately $14.8 million during fiscal 2002.
This provision relates to the estimated losses of $18.1 million from three customers, each of whom filed for
bankruptcy protection during fiscal 2002, offset by a payment of $3.3 million of the gross outstanding accounts
receivable balance due from iaxis Limited through the Company’s sales agreement with Dynegy.

The Company writes down its inventory for estimated obsolescence or unmarketable inventory equal

to the difference between the cost of inventory and the estimated market value based on assumptions
about future demand and market conditions. As a result of the further decline in capital spending by the
Company’s customers and a further decline in forecasted revenues of existing products in fiscal 2002, the
Company recorded a provision for excess inventory and purchase commitments of $286.5 million, which
included charges of $250.5 million for excess inventory and obsolescence and $36.0 million for excess
inventory purchase commitments.

(10) 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):

On June 21, 2002, CIENA assumed the outstanding ONI 5.00% convertible subordinated notes, in an aggre-

gate principal amount of $300 million, due October 15, 2005. Interest is payable on April 15 and October 15
of each year. The ONI convertible subordinated notes were initially recorded at a value of $218.0 million based
upon the present value of the outstanding notes at the time of the acquisition. CIENA is accreting the difference
between the present value of the notes at the time of the acquisition and the principal value over the remaining
period to October 15, 2005, such that the carrying value of the outstanding notes equals the principal value
at the time the notes become due. Accretion of the principal was $8.2 million for the period of June 21, 2002
to October 31, 2002.

The ONI convertible subordinated notes may be converted into shares of CIENA’s common stock at any

time before their maturity. The conversion rate is 7.7525 shares per each $1,000 principal amount of notes,
subject to adjustment in certain circumstances. On or after October 16, 2003, 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 principal amount):

During the fourth quarter of fiscal 2002, CIENA purchased on the open market $97.1 million of the
$300 million outstanding ONI convertible subordinated notes. The Company paid $75.2 million for notes
with a cumulative accreted book value of $72.5 million, which resulted in a loss on early extinguishment 
of debt of $2.7 million.

(11) 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).

(12) 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 share-
holders 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 exer-
cise 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
were 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.

10-K CIENA Corporation

During fiscal 2002, the Company established a valuation allowance against its deferred tax assets. The

Company intends to maintain a valuation allowance until sufficient positive evidence exists to support its reversal.
As of October 31, 2002, the Company had a $1.5 billion net operating loss carry forward and a $63.2 million
income tax credit carry forward which begin to expire in fiscal year 2020 and 2012 respectively. The Company’s
ability to use net operating losses and credit carry forwards may be subject to limitations pursuant to the
ownership change rules of the Internal Revenue Code Section 382.

The income tax provision does not reflect the tax savings resulting from deductions associated with the

Company’s stock. Approximately $83.2 million of the valuation allowance as of October 31, 2002 was attribut-
able to deductions associated with the Company’s stock, the benefit of which will be credited to additional
paid-in capital when realized. Tax benefits from deductions associated with the Company’s stock of approxi-
mately $154.6 million and $71.6 million in fiscal 2000 and fiscal 2001 respectively, were credited directly to
additional paid in capital.

Approximately $252.3 million of the valuation allowance as of October 31, 2002 was attributable to deferred

tax assets associated with the acquisition of ONI, that when realized, will first reduce goodwill, then other
non-current intangibles of ONI, and then income tax expense.

The IRS is currently scheduled to examine the Company’s federal income tax returns for fiscal 1999 and

fiscal 2000. 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 flow.

(14) 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, 2002, 57,175,278 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, 2002, 51,805,752 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 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 employee 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 result of the Company’s purchase of ONI, the Company assumed the ONI 1997 Stock Option Plan, the
ONI 1998 Stock Option Plan, the ONI 1999 Stock Option Plan and the ONI 2000 Stock Option Plan (“the ONI
2000 Plan”). The ONI 2000 Plan provided for the granting of stock options to employees and consultants 
of ONI. Options granted under the ONI 2000 Plan were either incentive stock options or non-statutory stock
options. Incentive stock options (“ISO”), could be granted only to ONI employees (including officers and
directors who were also employees). Non-statutory stock options (“NSO”) could be granted to ONI employees
and consultants. The Company has reserved 23,551,823 shares of Common Stock for outstanding options
under the plan. Early exercised options 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 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. Early exercised options 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 Option
Plan (“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. Early exercised options 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. Early exercised options 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 deter-
mined by the Board of Directors.

upon exercise. As of October 31, 2002, approximately 66.0 million shares are available for issuance under
these plans.

On April 17, 2002, and subsequently amended on April 19 and May 2, 2002, CIENA filed with the U.S.

Securities and Exchange Commission a Tender Offer Statement on Schedule TO (the “Schedule TO”), relating
to an offer by the Company to exchange options outstanding under the Third Amended and Restated 1994
Stock Option Plan (the “1994 Plan”), the 1999 Non-Officer Stock Option Plan (the “1999 Plan”) and the Cyras
Systems, Inc. 1998 Plan (“the Cyras Plan”) held by eligible employees to purchase shares of the Company’s
common stock, par value $0.01 per share (the “Common Stock”), having an exercise price greater than
$12.00 per share (the “Options”) for new options (the “New Options”) to purchase shares of the Common
Stock. The New Options exchanged for Options tendered under the 1994 and the 1999 Plan are to be
granted under the 1999 Plan, and the New Options exchanged for Options tendered under the Cyras Plan
are to be granted under the Cyras Plan, all upon the terms and subject to the conditions described in the
Offer to Exchange and the related Letter of Transmittal (the “Letter of Transmittal” and, together with the
Offer to Exchange, “Offer”). Except for options that were granted after October 16, 2001, the Company will
grant a New Option for one Option Share for every Option for two Option Shares that the Company accepted
for exchange, and the number of shares of Common Stock subject to the New Options will be equal to one
half of the number of shares of Common Stock subject to the Options that are accepted for exchange. With
respect to options that were granted after October 16, 2001, the Company will grant a New Option to purchase
the number of shares of Common Stock equal to the number of shares of Common Stock subject to the
Options that are accepted for exchange. Employees tendered Options to purchase 15.1 million shares on
May 17, 2002. On November 19, 2002, CIENA reissued New Options for approximately 6.4 million shares of
stock. The exercise price of the New Options was $4.53.

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 1,927,000, 424,000, and 693,000 shares of common stock have been issued for $10.0 mil-
lion, $7.8 million, and $5.8 million during fiscal 2002, 2001 and 2000, respectively. As of October 31, 2002
approximately 1.3 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 2000, 2001 and 2002 consistent with the provi-
sions 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 2001 would have been increased to the

The weighted average fair value of each option granted under the various stock option plans for 2000,

2001 and 2002 is $64.99, $27.92 and $4.88 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 2000, 2001 and 2002:

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 60% 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 each pay period, with a five year vesting plan applicable to the Company’s contribution with
the exception that participants vest immediately upon turning age fifty-five. Employees that involuntarily sepa-
rated from CIENA due to a reduction in force were also 100% vested in the employer match. During fiscal 2000,
2001 and 2002 the Company made matching contributions of approximately $2.3 million, $3.7 million and
$4.1 million respectively.

(15) Commitments and Contingencies
Operating Lease Commitments
The Company has certain minimum obligations under non-cancelable operating leases expiring on various
dates through 2019 for equipment and facilities. Future annual minimum rental commitments under non-
cancelable operating leases at October 31, 2002 are as follows (in thousands):

Rental expense for fiscal 2000, 2001 and 2002 was approximately $13.7 million, $19.5 million and $24.7 mil-

lion, respectively. In addition the Company paid approximately $0.0, $0.0 and $7.2 million related to rent
costs for restructured facilities and unfavorable lease commitments, respectively, which was offset against
the Company’s restructuring liabilities and unfavorable lease obligations, respectively.

Purchase Commitments with Contract Manufacturers and Suppliers
The Company relies on a small number of contract manufacturers to perform the majority of the manufacturing
operations for its products. In order to reduce lead times and ensure adequate component supply, the Company
enters into agreements with these suppliers which allows them to procure inventory for the Company’s forecasted
future demands. As of October 31, 2002, the Company has purchase commitments of $35.6 million.

Litigation
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. The complaint seeks injunctive relief, royalties and damages. CIENA has still not
been served in the case. CIENA is currently engaged in discussions with the plaintiff regarding settlement of
the matter. CIENA is unable to determine whether the litigation or any settlement CIENA may reach will have
an adverse effect on us.

On July 19, 2000, CIENA and CIENA Properties, Inc., a wholly owned subsidiary of CIENA, filed a com-

plaint 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 three 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. On February 7, 2001, CIENA and CIENA
Properties, Inc. filed an amendment to the complaint to add two additional patents relating to CIENA’s opti-
cal networking communications systems and technology. On March 19, 2001, Corvis filed an Answer and
Counterclaim to the amended complaint alleging invalidity, non-infringement and unenforceability of the newly
asserted patents. The discovery phase of the litigation is now completed. The court has postponed the trial,
originally scheduled to begin on April 1, 2002. CIENA anticipates that it will now take place in February 2003.
CIENA believes that Corvis’ counterclaims are without merit, and intends to defend itself vigorously.

On August 19, 2002, Pirelli S.p.A. and certain of its affiliates (“Pirelli”) filed a complaint against us in the
United States District Court for the District of Delaware alleging that CIENA was in breach of the Company’s
obligation to pay royalties under a license agreement that was part of the resolution of an earlier series of
disputes between us and Pirelli. CIENA has reached an agreement with Pirelli to resolve the lawsuit. Under
the terms of the settlement, CIENA will pay Pirelli $11.0 million, and Pirelli will forego claims to all other royal-
ties, past or future.

Upon acquiring ONI Systems, CIENA became the defendant in a lawsuit originally brought on March 10,
2000, against ONI by Nortel Networks in the United States District Court for the Northern District of California.
The suit alleges that ONI Systems’ products infringe a patent held by Nortel Networks, and sets forth allega-
tions of misappropriation of trade secrets, unlawful business practices and common law unfair competition.
Nortel Networks is seeking preliminary and permanent injunctions and damages in connection with its claims.
If it were to obtain an injunction preventing the sale of the allegedly infringing products, CIENA could lose
revenue or be required to incur expenses to modify the products to avoid infringement. CIENA could also be
ordered to pay damages, which could be substantial. CIENA believes, however, that we have valid defenses
to the claims, and CIENA intends to continue to defend the lawsuit vigorously. Trial in the case is currently
scheduled for January 2003.

In addition, on November 27, 2002, Nortel Networks filed a complaint in the United States District Court

for the Eastern District of Texas alleging that additional CIENA products infringe patents held by Nortel
Networks. The complaint seeks injunctive relief, royalties and damages. CIENA has still not been served in the
case. CIENA believes CIENA has good defenses to the complaint, and if Nortel prosecutes it, CIENA intends
to defend the action vigorously. If Nortel Networks were to prevail, however, there is a possibility that CIENA
may have to negotiate a license agreement, pay substantial royalties or modify the Company’s products to
avoid infringement.

As a result of the merger with ONI, CIENA also became a defendant in two substantially identical pur-

ported class actions on behalf of ONI security holders originally brought against ONI and members of its
board of directors. The complaints allege that the director defendants breached their fiduciary duties to
ONI in approving the merger with CIENA and seek declaratory, injunctive and other relief permitted by

63

10-K CIENA Corporation

equity. The plaintiffs failed to obtain an injunction against completion of the merger. CIENA believes that
these lawsuits are without merit and will continue to defend them vigorously. The first of these cases was
filed on February 20, 2002, in the Superior Court of the State of California, County of San Mateo, and is encap-
tioned K.W. Sams, On Behalf of Himself and All Others Similarly Situated v. ONI Systems Corporation, et al.
The second case was brought on March 19, 2002, in the Superior Court of the State of California, County of
Santa Clara, and is encaptioned Steven Myeary, On Behalf of Himself and All Others Similarly Situated v. ONI
Systems Corporation.

As a result of the merger with ONI, CIENA also became a defendant in a securities class action lawsuit.
Beginning in August 2001, a number of substantially identical class action complaints alleging violations of
the federal securities laws were filed in the United States District Court for the Southern District of New York.
These complaints name ONI, Hugh C. Martin, ONI’s former chairman, president and chief executive officer;
Chris A. Davis, ONI’s former executive vice president, chief financial officer and administrative officer; and cer-
tain underwriters of ONI’s initial public offering as defendants. The complaints were consolidated into a single
action, and a consolidated amended complaint was filed on April 24, 2002. The amended complaint alleges,
among other things, that the underwriter defendants violated the securities laws by failing to disclose alleged
compensation arrangements (such as undisclosed commissions or stock stabilization practices) in the initial
public offering’s registration statement and by engaging in manipulative practices to artificially inflate the
price of the Company’s common stock after the initial public offering. The amended complaint also alleges
that ONI and the named former officers violated the securities laws on the basis of an alleged failure to dis-
close the underwriters’ alleged compensation arrangements and manipulative practices. No specific amount
of damages has been claimed. Similar complaints have been filed against more than 300 other issuers that
have had initial public offerings since 1998, and all of these actions have been included in a single coordinated
proceeding. CIENA intends to defend these actions vigorously.

On May 3, 2002, a shareholder derivative complaint alleging violations of California state law was filed
in the Superior Court of the State of California, County of Santa Clara against ONI. As a result of the merger
with ONI CIENA has also become a defendant in the lawsuit. The complaint names Hugh Martin; the other
members of the ONI’s board of directors; Terrence J. Schmid, ONI’s former chief financial officer and vice
president, finance and administration; and certain underwriters of ONI’s initial public offering as defendants.
The complaint alleges that the defendants breached their fiduciary duties, acted negligently and were unjustly
enriched in determining the offering price of ONI Systems common stock in ONI’s initial public offering.
No specific amount of damages has been claimed. The complaint is encaptioned Sabrina J. Kurzman and
Michael J. Kurzman, Derivatively on Behalf of ONI Systems Corp. v. Hugh C. Martin. In September 2002,
CIENA filed a motion to dismiss the complaint. The Company’s motion to dismiss was granted by the court
on November 6, 2002. On December 2, 2002, the plaintiffs filed a notice of appeal from the court’s order.

(16) 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 oper-
ating 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.

(17) Subsequent Events
On December 12, 2002, CIENA filed with the U.S. Securities and Exchange Commission a Tender Offer
Statement on Schedule TO (the “Schedule TO”), relating to an offer by CIENA to purchase the remaining
outstanding $202.9 million ONI 5.0% convertible subordinated notes. CIENA’s purpose in seeking to repurchase
the notes is to reduce its annual interest expense and eliminate the need to repay or refinance the debt at
maturity in 2005. The tender offer is not contingent on financing. The notes are convertible into CIENA common
stock at a conversion rate of approximately 7.7525 shares per $1,000 principal amount held, subject to adjustment.
The purchase price for the notes will be $860 in cash per $1,000 principal amount, plus accrued and unpaid
interest up to but not including, the date of payment. If CIENA succeeds in purchasing all of the outstanding
ONI notes at $860 in cash per $1,000 principal amount, plus accrued and unpaid interest, CIENA will record a
loss of $18.7 million related to the extinguishment of the ONI convertible subordinated notes. The loss is due
to the fact that the accreted value of the note is less than the purchase price. CIENA will use the Company’s
cash and cash equivalents, and short-term investment to fund the note purchase.
