	•	Telecommunications. Service providers in the telecommunications industry are faced with deregulation, globalization, increased competition, and often a substantial debt burden. As a result, they must control infrastructure costs while maintaining or improving services to existing customers and at the same time identifying and developing compelling new revenue streams in order to grow their business. Network Appliance’s products and solutions allow these providers to quickly and cost-effectively build the network storage infrastructure and content delivery networks required by the global telecommunications industry.

Customer Challenges

Network Appliance enterprise network storage solutions directly address the major information technology challenges that enterprises face — consolidating rapidly growing quantities of storage, reducing costs associated with data center operations, ensuring business continuance, and managing data throughout the globally distributed enterprise.


	•	Storage consolidation. Managing the explosive growth of data is one of the greatest challenges enterprises face today. Network Appliance gives enterprises the scalable solutions they need to consolidate storage from hundreds or thousands of servers and manage storage efficiently in a mixed server environment.

	•	Data center operations. More than just applications and hardware, the data center is the nerve center of an organization, controlling the flow of information throughout the enterprise. Many of the costs that drive up the total cost of information technology (IT) ownership are associated with data center operations, and include tasks such as data backup and recovery, hardware and software maintenance, performance management, and resource allocation. Our simplified appliance architecture automates or eliminates many of these administrative tasks, and delivers simple, centrally managed, and flexible data storage that leverages and increases the performance of existing IT infrastructures.

	•	Business continuance. Many enterprises are increasingly focused on disaster preparedness and recovery and must avoid costly downtime in the event of a major disaster or localized disruption. Minutes of downtime are costly, and hours of downtime can be catastrophic. Working in tandem with


		the existing network infrastructure (both Fibre Channel and Ethernet), our storage appliances and data management software enable customers to implement disaster recovery and data mirroring plans quickly and effectively, while minimizing incremental telecommunications and administration costs.

	•	Distributed enterprise. As enterprises grow, it becomes increasingly difficult to provide timely information to remote locations and branch offices, jeopardizing their productivity. NetApp products accelerate information access and application performance while reducing bandwidth costs, and also reduce the cost and complexity associated with managing the data in these distributed offices. Our solutions enable enterprises to quickly replicate and relay information to and from one or many locations, fully protecting data in remote offices and locations.

A Solution-Based Approach

To solve these customer challenges, Network Appliance offers a growing number of integrated solutions that address the specific data management hurdles faced by our enterprise customers. These turnkey solutions, which include hardware, software, service, and financing components, enable our customers to simplify their storage management, leverage their existing infrastructure, and increase their return on investment. The solutions that have received the greatest level of interest to date include:

Our partnerships with service providers such as Accenture, Computer Sciences Corporation, and IBM Global Services allow us to better serve customers by broadening service offerings, as well as leveraging existing service and support relationships that customers may already have in place.

Classes of Data

NetApp products and solutions are based on the premise that not all data is created equal. Enterprise customers face a significant challenge in designing networked storage infrastructures that balance the availability requirements of their applications and associated data with the cost of the storage solution. Storing all data on an expensive, monolithic, mainframe-class array is no longer acceptable to customers who must carefully evaluate the value of their information. As a result, data is being classified by availability and performance requirements in relation to cost.


	•	Business-critical data. Business-critical applications, including trading-floor applications and ERP systems, require the highest levels of availability and reliability, have more dedicated management resources, and exhibit the least amount of cost sensitivity. If this data is unavailable, the business is typically not generating revenue and may incur other financial penalties.

	•	Business operations data. This category includes data used by externally visible business operations applications, including e-mail, customer support applications, and external Web sites. If this data is unavailable, it may be apparent to customers and prospects, impacting revenue and reflecting poorly on the organization. As such, this data has higher reliability and availability requirements, and typically requires more significant storage infrastructure and data management software investments.

	•	Business internal data. This class of data is accessed by internal employees, and while the availability of the data is not important to customers outside the business, it can have a big impact on the users of the data inside the business. Examples of business internal data could include corporate intranets, HR systems, and data warehouses used for analytical purposes.

	•	Departmental and remote office data. Departmental and remote-office deployments also require a low-cost solution, but typically need higher levels of availability with low management overhead. Data in this class is typically not used outside the department or remote office, and if the data becomes unavailable, the impact to the overall business is minimal.

	•	Reference data. Types of reference data include e-mail archives; bank, brokerage, and billing statements; medical images and records; MCAD drawings; integrated chip designs; and seismic and satellite data. Customers require fast data access at costs comparable to much slower high-end tape or optical libraries, with minimal ongoing management cost.


	•	Archive data. Enterprises require a very low-cost storage solution for archive data and backups, which have historically been stored on magnetic tape. Many customers are now storing archive data on more flexible disk-based systems, such as the NetApp NearStore^TM, which reduces backup windows and enables rapid recovery in the event of a disaster.

Network Appliance solutions meet the needs of archive, reference, departmental/remote office, business internal, business operations, and business critical data with a common product architecture and data management methodology, enabling customers to easily deploy and manage all their networked storage infrastructure in the same way.

System Products

NetApp products consist of fabric-attached storage (FAS) appliances, also known as filers, NearStore systems, NetCache® content delivery appliances, data management and content delivery software, and professional and support services. Our configured appliances range in price from $4,000 to more than $1,000,000.

All NetApp systems come packaged in rack-mountable enclosures that can be installed in a customer’s existing server racks or factory-installed and configured in cabinets. Our appliances are based primarily on commodity hardware, including Intel® Pentium® processors, an advanced implementation of the industry-standard PCI bus architecture, standard Ethernet adapters, and either Fibre Channel-Arbitrated Loop (FC-AL), Advanced Technology Attachment (ATA), or Small Computer System Interface (SCSI) disk interconnects.


	Filers

NetApp filers are scalable, highly available, field-proven, unified networked storage systems for data storage and simplifying data management. The filer appliances are easy to install, configure, and manage. They are specifically designed for highly scalable, network-centric IT system architectures, and support both network-attached storage (“NAS”) and storage-attached networks (“SAN”) on a single, unified platform. Our filers are designed for and deliver lower total cost of ownership than alternative competitive systems. Heterogeneous data sharing allows our systems to deliver simultaneous data access to Linux, UNIX, Windows, and Web-based servers and clients, dramatically lowering the total cost of ownership and management complexity versus homogeneous storage systems. Filers are available in either single-node configurations or fully redundant, active/active cluster configurations that provide high data availability for business-critical environments.

	•	NetApp F880c/F880 and F825c/F825 enterprise servers. The balance of capacity and performance with flexible I/O configuration enables the NetApp F880c and F825c to power a broad range of large-scale applications. Currently deployed in the largest service provider networks and data-intensive


		environments, including those running database/ERP and other enterprise-level applications, the F880 and F825 are proven high-performance workhorses.

	•	NetApp F810c/F810. The NetApp F810c server is designed for small to medium-size enterprise applications. By using the same Data ONTAP^TM operating system as higher-capacity, higher-performance servers, the F810c is fully compatible with them and serves as a cost-efficient starting point in building a network infrastructure on NetApp systems.

	•	NetApp FAS250 filer. The NetApp FAS250 is an entry-level enterprise filer supporting capacities up to 1TB in a compact form factor. The FAS250 is completely software compatible with all other NetApp products and uses the same storage shelves and Fibre Channel disks currently available for the F800 and FAS900 series filers. The FAS250 provides customers with an attractive entry-level price and a simple upgrade path to higher-capacity, higher-performance filers.

	•	NetApp F87 filer. The NetApp F87 filer is targeted at workgroup and remote branch office environments.

Segment and Geographic Information

See Note 8 to the Consolidated Financials Statements accompanying this Annual Report on Form 10-K.

Seasonality

Although operating results have not been materially and adversely affected by seasonality in the past, because of the significant seasonal effects experienced within the industry, particularly in Europe, our future operating results could be materially adversely affected by seasonality. See “Risk Factors — Factors beyond our control could cause our quarterly results to fluctuate” and “Risks inherent in our international operations

could have a material adverse effect on our operating results” accompanying this Annual Report on Form 10-K.

Sales and Marketing

Network Appliance markets and distributes products globally in over 90 countries employing a multichannel distribution strategy, which focuses on product sales to end users through a direct sales force, value-added resellers, system integrators, and original equipment manufacturers (OEM). In North America, we employ all forms of distribution previously mentioned, with a focus on direct sales to our strategic and named accounts. In Europe, we employ a mix of resellers and direct sales channels to sell to end users. In Asia, our products are primarily sold through resellers, which are supported by channel sales representatives and technical support personnel. No single customer accounted for 10% or more of net sales in fiscal 2003, 2002, or 2001.

Backlog

Network Appliance manufactures products based on a combination of specific order requirements and forecasts of our customers’ demand. Orders are generally placed by customers on an as-needed basis. Products are typically shipped within one to four weeks following receipt of an order. In certain circumstances, customers may cancel or reschedule orders without penalty. For these reasons, “orders” may not constitute a firm backlog and may not be a meaningful indicator of revenues.

Manufacturing

Manufacturing operations, with insourced and outsourced locations in Sunnyvale, California, and Glasgow, Scotland, include materials procurement, commodity management, component engineering, test engineering, manufacturing engineering, product assembly, product assurance, quality control, and final test. We rely on many suppliers for materials, as well as several key subcontractors for the production of certain subassemblies and finished systems. Our strategy has been to develop close relationships with our suppliers, exchanging critical information and implementing joint quality-training programs. We also use contract manufacturers for the production of major subassemblies to improve our manufacturing redundancy. See “Risk Factors — We rely on a limited number of suppliers” and “Risk Factors — The loss of our contract manufacturers.” This manufacturing strategy minimizes capital investment and overhead expenditures and creates flexibility for rapid expansion. We were awarded the ISO 9001 certification on May 29, 1997, and continue to be ISO-certified.

Research and Development

During fiscal year 2003, Network Appliance launched unified storage platforms designed to support both SAN and NAS simultaneously. We introduced a number of new systems, including the F825 midrange filer, the FAS940 and FAS960 high-end filers, the NetCache C1200 and C2100, and the NearStore R150, which continues to define a new category of storage solution. We completed the development of the new FAS250 entry-level enterprise filer, and began delivery to customers in the first quarter of fiscal year 2004. We also launched new software products that significantly improve data management capabilities, provide new solutions in the areas of data protection and backup and recovery, and enable new business continuance functionality.

See “Risk Factors — If we are unable to develop and introduce new products and respond to technological change, or if our new products do not achieve market acceptance, our operating results could be materially adversely affected.”

Competition

The storage and content delivery markets are intensely competitive and are characterized by rapidly changing technology.

In the storage market, our FAS appliances and data management software compete primarily against storage products and data management software from EMC Corporation, Hitachi Data Systems, Hewlett-Packard Company (including the integrated Compaq Computer Corporation), IBM Corporation, and Sun Microsystems, Inc. We have also historically encountered less-frequent competition from companies including Dell, LSI Logic Corp., MTI Corp., Procom Technology, and Silicon Graphics, Inc.

In the content delivery market, our NetCache appliances and content delivery software compete against caching appliance and content delivery software vendors including Akamai Technologies, Inc., BlueCoat Systems (formerly CacheFlow, Inc.), and Cisco Systems, Inc.

Additionally a number of new, privately held companies are currently attempting to enter the storage and content delivery markets, some of which may become significant competitors in the future.

See “Risk Factors — An increase in competition could materially adversely affect our operating results” and “If we are unable to develop and introduce new products and respond to technological change, or if our new products do not achieve market acceptance.”

Proprietary Rights

We currently rely on a combination of copyright and trademark laws, trade secrets, confidentiality procedures, contractual provisions, and patents to protect our proprietary rights. We seek to protect our software, documentation, and other written materials under trade secret, copyright, and patent laws, which afford only limited protection. We have registered our Network Appliance name and logo, FAServer®, FilerView, NetApp, NetCache, SecureShare® SnapManager, SnapMirror, SnapRestore, and WAFL as trademarks in the United States (“U.S.”). Other U.S. trademarks and some of the other U.S. registered trademarks are registered internationally as well. We will continue to evaluate the registration of additional trademarks as appropriate. We generally enter into confidentiality agreements with our employees, resellers, and customers. We currently have multiple U.S. and international patent applications pending and multiple U.S. patents issued. See “Risk Factors — If we are unable to protect our intellectual property, we may be subject to increased competition that could materially adversely affect our operating results.”

Employees

As of April 25, 2003, we had 2,345 employees. Of the total, 1,199 were in sales and marketing, 526 in research and development, 283 in finance and administration, and 337 in manufacturing and customer service operations. Our future performance depends in significant part on our key technical and senior management personnel, none of whom is bound by an employment agreement. We have never had a work stoppage and consider relations with our employees to be good.

Risk Factors

The following risk factors and other information included in this Annual Report on Form 10-K should be carefully considered. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we presently deem less significant may also impair our business operations. Please see page [3] of this Annual Report on Form 10-K for additional discussion of these forward-looking statements. If any of the following risks actually occur, our business, operating results, and financial condition could be materially adversely affected.


	*Factors beyond our control could cause our quarterly results to fluctuate.*

We believe that period-to-period comparisons of our results of operations are not necessarily meaningful and should not be relied upon as indicators of future performance. Many of the factors that could cause our quarterly operating results to fluctuate significantly in the future are beyond our control and include, but are not limited to, the following:


	•	changes in general economic conditions and specific economic conditions in the computer, storage, and networking industries;

	•	general decrease in global corporate spending on information technology leading to a decline in demand for our products;

	•	the effects of terrorist activity and international conflicts, which could lead to business interruptions and difficulty in forecasting;

	•	the level of competition in our target product markets;

	•	the size, timing, and cancellation of significant orders;

	•	product configuration and mix;

	•	the extent to which our customers renew their service and maintenance contracts with us;

	•	market acceptance of new products and product enhancements;

	•	announcements, introductions, and transitions of new products by us or our competitors;

	•	deferrals of customer orders in anticipation of new products or product enhancements introduced by us or our competitors;

	•	changes in pricing by us in response to competitive pricing actions;

	•	our ability to develop, introduce, and market new products and enhancements in a timely manner;

	•	supply constraints;

	•	technological changes in our target product markets;

	•	the levels of expenditure on research and development and sales and marketing programs;

	•	our ability to achieve targeted cost reductions;

	•	excess facilities;

	•	future accounting pronouncements and changes in accounting policies; and

	•	seasonality.

In addition, sales for any future quarter may vary and accordingly be inconsistent with our plans. We manufacture products based on a combination of specific order requirements and forecasts of our customer

demands. Products are typically shipped within one to four weeks following receipt of an order. In certain circumstances, customers may cancel or reschedule orders without penalty. Product sales are also difficult to forecast because the network storage market is rapidly evolving and our sales cycle varies substantially from customer to customer.

Due to all of the foregoing factors, it is possible that in one or more future quarters our results may fall below the expectations of public market analysts and investors. In such event, the trading price of our common stock would likely decrease.


	*Our gross margins may vary based on the configuration of our products, and such variation may make it more difficult to forecast our earnings.*

We derive a significant portion of our sales from the resale of disk drives as components of our filers, and the resale market for hard disk drives is highly competitive and subject to intense pricing pressures. Our sales of disk drives generate lower gross margin percentages than those of our filer products. As a result, as we sell more highly configured systems with greater disk drive content, overall gross margin percentages may be negatively affected.

Our gross margins have been and may continue to be affected by a variety of other factors, including:


	•	demand for storage and content delivery products;

	•	discount levels and price competition;

	•	direct versus indirect sales;

	•	product and add-on software mix;

	•	the mix of services as a percentage of revenue;

	•	the mix and average selling prices of products;

	•	the mix of disk content;

	•	new product introductions and enhancements;

	•	excess inventory purchase commitments as a result of changes in demand forecasts and possible product and software defects as we transition our products; and

	•	the cost of components, manufacturing labor, and quality.


	*A significant percentage of our expenses are fixed, which could affect our net income.*

Our expense levels are based in part on our expectations as to future sales and a significant percentage of our expenses are fixed. As a result, if sales levels are below expectations or previously higher levels, net income will be disproportionately affected in a material and adverse manner.


	*Cost and expense control may be critical to maintaining positive cash flow from operations and profitability.*

In fiscal 2002, we reduced fixed costs through workforce reductions and a consolidation of facilities. We believe strict cost containment is essential to maintaining positive cash flow from operations and remaining profitable in future quarters, especially since the outlook for future quarters is uncertain. Additional measures to reduce expenses may be undertaken if revenues and market conditions do not improve. A number of factors could preclude us from successfully bringing costs and expenses in line with our revenues, such as our inability to accurately forecast business activities and deterioration of our revenues. If we are not able to effectively control our costs and achieve an expense structure commensurate with our business activities and revenues, our cash flow and net income will be adversely affected.


	Our future financial performance depends on growth in the network storage and content delivery markets; if these markets do not continue to grow at the rates at which we forecast growth, our operating results will be materially and adversely impacted.

All of our products address the storage and content delivery markets. Accordingly, our future financial performance will depend in large part on continued growth in the storage and content delivery markets and on our ability to adapt to emerging standards in these markets. We cannot assure you that the markets for storage and content delivery will continue to grow or that emerging standards in these markets will not adversely affect the growth of UNIX, Windows, and the World Wide Web server markets upon which we depend. In addition, our business also depends on general economic and business conditions. A reduction in demand for network storage and content delivery caused by weakening economic conditions and decreases in corporate spending have resulted in decreased revenues and lower revenue growth rates. The network storage and content delivery market growth declined significantly beginning in the third quarter of fiscal 2001, causing both our revenues and operating results to decline. If the network storage and content delivery markets grow more slowly than anticipated or if emerging standards other than those adopted by us become increasingly accepted by these markets, our operating results could be materially adversely affected.


	*The market price for our common stock has fluctuated significantly in the past and will likely continue to do so in the future.*

The market price for our common stock has experienced substantial volatility in the past, and several factors could cause the price to fluctuate substantially in the future. These factors include:


	•	fluctuations in our operating results;

	•	fluctuations in the valuation of companies perceived by investors to be comparable to us;

	•	economic developments in the network storage market as a whole;

	•	international conflicts and acts of terrorism;

	•	a shortfall in revenues or earnings compared to securities analysts’ expectations;

	•	changes in analysts’ recommendations or projections;

	•	announcements of new products, applications or product enhancements by us or our competitors;

	•	changes in our relationships with our suppliers, customers and strategic partners; and

	•	general market conditions.

In addition, the stock market has experienced volatility that has particularly affected the market prices of equity securities of many high-technology companies. Additionally, certain macroeconomic factors such as changes in interest rates, the market climate for the high-technology sector, and levels of corporate spending on information technology could also have an impact on the trading price of our stock. As a result, the market price of our common stock may fluctuate significantly in the future and any broad market decline, as well as our own operating results, may materially adversely affect the market price of our common stock.


	If we are unable to develop and introduce new products and respond to technological change, if our new products do not achieve market acceptance, or if we fail to manage the transition between our new and old products, our operating results could be materially adversely affected.

Our future growth depends upon the successful development and introduction of new hardware and software products. Due to the complexity of storage subsystems and Internet caching devices, and the difficulty in gauging the engineering effort required to produce new products, such products are subject to significant technical risks. However, we cannot assure you that any of our new products will achieve market acceptance. Additional product introductions in future periods may also impact the sales of existing products. In addition, our new products must respond to technological changes and evolving industry standards. If we are unable, for technological or other reasons, to develop and introduce new products in a timely manner in

response to changing market conditions or customer requirements, or if such products do not achieve market acceptance, our operating results could be materially adversely affected.

In particular, in conjunction with the introduction of our product offerings in the fabric-attached storage market, we introduced products with new features and functionality that address the storage area network market. During fiscal 2003, we introduced iSCSI-enabled unified storage solutions. We also introduced Direct Access File System (DAFS) protocol-capable products and NearStore backup and recovery products during fiscal 2002. We face risks relating to these product introductions, including risks relating to forecasting of demand for such products, as well as possible product and software defects and a potentially different sales and support environment associated with selling these new systems. If any of the foregoing occur, our operating results could be adversely affected.

As new or enhanced products are introduced, we must successfully manage the transition from older products in order to minimize disruption in customers’ ordering patterns, avoid excessive levels of older product inventories, and ensure that enough supplies of new products can be delivered to meet customers’ demands.


	*Our business could be materially adversely affected as a result of a natural disaster, terrorist acts, or other catastrophic event.*

Our operations, including our suppliers’ and contract manufacturers’ operations, are susceptible to outages due to fire, floods, power loss, power shortages, telecommunications failures, break-ins, and similar events. In addition, our headquarters are located in Northern California, an area susceptible to earthquakes. If any significant disaster were to occur, our ability to operate our business could be impaired.

Weak economic conditions or terrorist actions could lead to significant business interruptions. If such disruptions result in cancellations of customer orders, a general decrease in corporate spending on information technology, or direct impacts on our marketing, manufacturing, financial functions, or our suppliers’ logistics function, our results of operations and financial condition could be adversely affected.


	We depend on attracting and retaining qualified technical and sales personnel; if we are unable to attract and retain such personnel, our operating results could be materially and adversely impacted.

Our continued success depends, in part, on our ability to identify, attract, motivate, and retain qualified technical and sales personnel. Because our future success is dependent on our ability to continue to enhance and introduce new products, we are particularly dependent on our ability to identify, attract, motivate, and retain qualified engineers with the requisite education, backgrounds, and industry experience. In spite of the economic downturn, competition for qualified engineers, particularly in Silicon Valley, can be intense. The loss of the services of a significant number of our engineers or sales people could be disruptive to our development efforts or business relationships and could materially adversely affect our operating results.


	*Risks inherent in our international operations could have a material adverse effect on our operating results.*

We conduct business internationally. For fiscal 2003, approximately 42.1% of our total revenues were from international customers (including U.S. exports). Accordingly, our future operating results could be materially adversely affected by a variety of factors, some of which are beyond our control, including regulatory, political, or economic conditions in a specific country or region, trade protection measures and other regulatory requirements, government spending patterns, and acts of terrorism and international conflicts.

Our international sales are denominated in U.S. dollars and in foreign currencies. An increase in the value of the U.S. dollar relative to foreign currencies could make our products more expensive and, therefore, potentially less competitive in foreign markets. For international sales and expenditures denominated in foreign currencies, we are subject to risks associated with currency fluctuations. We hedge risks associated with foreign currency transactions in order to minimize the impact of changes in foreign currency exchange rates on earnings. We utilize forward contracts to hedge our currency exposure associated with certain assets

and liabilities as well as anticipated foreign currency cash flow. All balance sheet hedges are marked to market through earnings every period, while gains and losses on cash flow hedges are recorded in other comprehensive income. There can be no assurance that such hedging strategy will be successful and that currency exchange rate fluctuations will not have a material adverse effect on our operating results.

Additional risks inherent in our international business activities generally include, among others, longer accounts receivable payment cycles, difficulties in managing international operations, and potentially adverse tax consequences. Such factors could materially adversely affect our future international sales and, consequently, our operating results.

Although operating results have not been materially adversely affected by seasonality in the past, because of the significant seasonal effects experienced within the industry, particularly in Europe, our future operating results could be materially adversely affected by seasonality.

We cannot assure you that we will be able to maintain or increase international market demand for our products.


	*An increase in competition could materially adversely affect our operating results.*

The storage and content delivery markets are intensely competitive and are characterized by rapidly changing technology.

Additionally a number of new, privately held companies are currently attempting to enter the storage and content delivery markets, some of which may become significant competitors in the future.

We believe that the principal competitive factors affecting the storage and content delivery markets include product benefits such as response time, reliability, data availability, scalability, ease of use, price, multiprotocol capabilities, and customer service and support. Although we believe that our products currently compete favorably with respect to these factors, we cannot assure you that we can maintain our competitive position against current and potential competitors, especially those with significantly greater financial, marketing, service, support, technical, and other resources.

Increased competition could result in price reductions, reduced gross margins, and loss of market share, any of which could materially adversely affect our operating results. Our competitors may be able to respond more quickly than we can to new or emerging technologies and changes in customer requirements, or devote greater resources to the development, promotion, sale, and support of their products. In addition, current and potential competitors have established or may establish cooperative relationships among themselves or with third parties. Accordingly, it is possible that new competitors or alliances among competitors may emerge and rapidly acquire significant market share. We cannot assure you that we will be able to compete successfully against current or future competitors. Competitive pressures we face could materially adversely affect our operating results.


	We rely on a limited number of suppliers, and any disruption or termination of these supply arrangements could delay shipment of our products and could materially adversely affect our operating results.

We rely on a limited number of suppliers of several key components utilized in the assembly of our products. We purchase most of our disk drives through a single supplier. We purchase computer boards and

microprocessors from a limited number of suppliers. Our reliance on a limited number of suppliers involves several risks, including:


	•	a potential inability to obtain an adequate supply of required components because we do not have long-term supply commitments;

	•	supplier capacity constraints;

	•	price increases;

	•	timely delivery; and

	•	component quality.

Component quality is particularly significant with respect to our suppliers of disk drives. In order to meet product performance requirements, we must obtain disk drives of extremely high quality and capacity. In addition, there are periodic supply-and-demand issues for disk drives, microprocessors, and for semiconductor memory components, which could result in component shortages, selective supply allocations, and increased prices of such components. We cannot assure you that we will be able to obtain our full requirements of such components in the future or that prices of such components will not increase. In addition, problems with respect to yield and quality of such components and timeliness of deliveries could occur. Disruption or termination of the supply of these components could delay shipments of our products and could materially adversely affect our operating results. Such delays could also damage relationships with current and prospective customers.

In addition, we license certain technology and software from third parties that is incorporated into our products. If we are unable to obtain or license the technology and software on a timely basis, we will not be able to deliver product to our customers in a timely manner.


	The loss of any contract manufacturers or the failure to accurately forecast demand for our products or successfully manage our relationship with our contract manufacturers could negatively impact our ability to manufacture and sell our products.

We currently rely on several contract manufacturers to manufacture most of our products. Our reliance on our third-party contract manufacturers reduces our control over the manufacturing process, exposing us to risks including reduced control over quality assurance, production costs, and product supply. If we should fail to effectively manage our relationship with our contract manufacturers, or if our contract manufacturers experience delays, disruptions, capacity constraints, or quality control problems in their manufacturing operations, our ability to ship products to our customers could be impaired and our competitive position and reputation could be harmed. Qualifying a new contract manufacturer and commencing volume production are expensive and time-consuming. If we are required to change contract manufacturers or assume internal manufacturing operations, we may lose revenue and damage our customer relationships. If we inaccurately forecast demand for our products, we may have excess or inadequate inventory, or incur cancellation charges or penalties, which could adversely impact our operating results.

We intend to regularly introduce new products and product enhancements, which will require us to rapidly achieve volume production by coordinating with our contract manufacturers and suppliers. We may need to increase our material purchases, contract manufacturing capacity, and internal test and quality functions to meet anticipated demand. The inability of our contract manufacturers to provide us with adequate supplies of high-quality products, or the inability to obtain raw materials, could cause a delay in our ability to fulfill orders.


	*If we are unable to maintain our existing relationships and develop new relationships with major strategic partners, our revenue may be impacted negatively.*

An element of our strategy to enhance revenue is to strategically partner with major third-party software and hardware vendors who integrate our products into their products and also comarket our products. A number of these strategic partners are industry leaders that offer us expanded access to segments of the storage

market. There is intense competition for attractive strategic partners, and even if we can establish strategic relationships with these partners, we cannot assure you that these partnerships will generate significant revenue or that the partnerships will continue to be in effect for any specific period of time.

We intend to continue to establish and maintain business relationships with technology companies to accelerate the development and marketing of our storage solutions. To the extent we are unsuccessful in developing new relationships and maintaining our existing relationships, our future revenue and operating results could be impacted negatively. In addition, the loss of a strategic partner could have a material adverse effect on the progress of new products under development with that partner.


	*We may incur problems with current or future equity investments and acquisitions, and these investments may not achieve our objectives.*

From time to time, we make equity investments for the promotion of business and strategic objectives. We have already made strategic investments in a number of network storage-related technology companies. Equity investments may result in the loss of investment capital. The market price and valuation of our equity investments in these companies may fluctuate due to market conditions and other circumstances over which we have little or no control, and recent events have adversely affected the public equity market. To the extent that the fair value of these securities is less than our cost over an extended period of time, our results of operations and financial position could be negatively impacted. In fiscal 2003, we recorded a non-cash, other-than-temporary write-down of $0.7 million related to the impairment of our investment in a publicly traded company. In the second quarter of fiscal 2002, we recorded a noncash, other-than-temporary write-down of $13.0 million related to impairments in publicly traded and private companies.

As part of our strategy, we are continuously evaluating opportunities to buy other businesses or technologies that would complement our current products, expand the breadth of our markets, or enhance our technical capabilities. We have acquired two companies since the beginning of fiscal 2001. We may engage in future acquisitions that dilute our stockholders’ investments and cause us to use cash, to incur debt, or to assume contingent liabilities.

Acquisitions of companies entail numerous risks, and we may not be able to successfully integrate acquired operations and products or to realize anticipated synergies, economies of scale, or other value. In addition, we may experience a diversion of management’s attention, the loss of key employees of acquired operations, or the inability to recover strategic investments in development stage entities. Any such problems could have a material adverse effect on our business, financial condition, and results of operation.

In addition, we adopted Statement of Financial Accounting Standards (“SFAS”) 142 “Goodwill and Other Intangible Assets,” which changes the accounting for goodwill from an amortization method to an impairment-only approach. As of May 1, 2002, the fair value for each of our reporting units exceeded the reporting unit’s carrying amount and no impairment was recognized. On an ongoing basis, goodwill is reviewed annually for impairment (or more frequently if indicators of impairment arise). As of April 30, 2003, there had been no impairment of goodwill and intangible assets. There can be no assurance that future impairment tests will not result in a charge to earnings. See Note 13 under Notes to Consolidated Financial Statements.


	We do not have exclusive relationships with our resellers and accordingly there is a risk that those resellers may give higher priority to products of other suppliers, which could materially adversely affect our operating results.

Our reseller partners generally offer products from several different companies, including products of our competitors. Accordingly, there is risk that these resellers may give higher priority to products of other suppliers, which could materially adversely affect our operating results.


	Undetected software, hardware errors, or failures found in new products may result in loss of or delay in market acceptance of our products, which could increase our costs and reduce our revenues.

Our products may contain undetected software, hardware errors, or failures when first introduced or as new versions are released. Despite testing by us and by current and potential customers, errors may not be found in new products until after commencement of commercial shipments, resulting in loss of or delay in market acceptance, which could materially adversely affect our operating results.


	If actual results or events differ materially from those contemplated by us in making estimates and assumptions, our reported financial condition and results of operation for future periods could be materially affected.

The preparation of the consolidated financial statements and related disclosure in conformity with accounting principles generally accepted in the United States of America requires management to establish policies that contain estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Note 2 of the Notes to Consolidated Financial Statements describes the significant accounting policies essential to preparing our consolidated financial statements. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures. We base our estimates on historical experience and assumptions that we believe to be reasonable under the circumstances. Actual future results may differ materially from these estimates. We evaluate, on an ongoing basis, our estimates and assumptions. In addition, see our Critical Accounting Policies under Item 7.


	*If we are unable to protect our intellectual property, we may be subject to increased competition that could materially adversely affect our operating results.*

Our success depends significantly upon our proprietary technology. We currently rely on a combination of copyright and trademark laws, trade secrets, confidentiality procedures, contractual provisions, and patents to protect our proprietary rights. We seek to protect our software, documentation, and other written materials under trade secret, copyright, and patent laws, which afford only limited protection. Some U.S. trademarks and some U.S.-registered trademarks are registered internationally as well. We will continue to evaluate the registration of additional trademarks as appropriate. We generally enter into confidentiality agreements with our employees and with our resellers, strategic partners, and customers. We currently have multiple U.S. and international patent applications pending and multiple U.S. patents issued. The pending applications may not be approved and if patents are issued, such patents may be challenged. If such challenges are brought, the patents may be invalidated. We cannot assure you that we will develop proprietary products or technologies that are patentable, that any issued patent will provide us with any competitive advantages or will not be challenged by third parties, or that the patents of others will not materially adversely affect our ability to do business.

Litigation may be necessary to protect our proprietary technology. Any such litigation may be time-consuming and costly. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or to obtain and use information that we regard as proprietary. In addition, the laws of some foreign countries do not protect proprietary rights to as great an extent as do the laws of the U.S. We cannot assure you that our means of protecting our proprietary rights will be adequate or that our competitors will not independently develop similar technology, duplicate our products, or design around patents issued to us or other intellectual property rights of ours.

We are subject to intellectual property infringement claims. We may, from time to time, receive claims that we are infringing third parties’ intellectual property rights. Third parties may in the future claim infringement by us with respect to current or future products, patents, trademarks, or other proprietary rights. We expect that companies in the appliance market will increasingly be subject to infringement claims as the number of products and competitors in our industry segment grows and the functionality of products in different industry segments overlaps. Any such claims could be time-consuming, result in costly litigation, cause product shipment delays, require us to redesign our products or require us to enter into royalty or

licensing agreements, any of which could materially adversely affect our operating results. Such royalty or licensing agreements, if required, may not be available on terms acceptable to us or at all.


Item 2.	*Properties*

Our headquarters site for corporate general administration, sales and marketing, research and development, customer services, and manufacturing operations occupies approximately 675,000 square feet of buildings in Sunnyvale, California. In fiscal 2002, we terminated our operating lease obligations for our Sunnyvale headquarters site by purchasing the land and buildings for $249.8 million.

We lease other sales offices and research and development facilities throughout the U.S. and internationally. We believe that our existing facilities and those being developed in Sunnyvale are adequate for our requirements over at least the next two years and that additional space will be available as needed.

As a result of reductions in headcount in fiscal 2002, we have exited office space under noncancellable leases in both the U.S. and Europe. If we are unable to successfully sublease our vacated and unoccupied office space, our operating results may be adversely affected. See Note 12 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

See additional discussion regarding properties in “Note 4 under Item 8. Financial Statements and Supplementary Data — Notes to Consolidated Financial Statements” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources.”


Item 3.	*Legal Proceedings*

We are subject to legal proceedings, claims, and litigation arising in the ordinary course of business. We defend ourselves vigorously against any such claims. While the outcome of these matters is currently not determinable, management does not expect that the ultimate costs to resolve these matters will have a material adverse effect on our consolidated financial position, results of operations, or cash flows.


Item 4.	*Submissions of Matters to a Vote of Security Holders*

No matters were submitted to a vote of security holders during the fourth quarter of the fiscal year covered by this Annual Report on Form 10-K.

PART II


Item 5.	*Market for Registrant’s Common Equity and Related Stockholder Matters*

Our common stock commenced trading on the Nasdaq National Market on November 21, 1995, and is traded under the symbol “NTAP.” As of April 25, 2003, there were 1,016 holders of record of the common stock. The following table sets forth for the periods indicated the high and low closing sale prices for our common stock as reported on the Nasdaq National Market.



	Fiscal 2003				Fiscal 2002

	High		Low		High		Low

First Quarter	$	18.04	$	9.25	$	28.21	$	9.88
Second Quarter		10.64		5.63		15.27		6.54
Third Quarter		14.35		8.92		26.89		11.78
Fourth Quarter		14.88		9.40		21.74		15.32

We believe that a number of factors may cause the market price of our common stock to fluctuate significantly. See “Item 1. Business — Risk Factors.”

We have never paid cash dividends on our capital stock. We currently anticipate retaining all available funds, if any, to finance internal growth and product development as well as other management initiatives, including stock repurchases and acquisitions. Payment of dividends in the future will depend upon our

earnings and financial condition and such other factors as the directors may consider or deem appropriate at the time.

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

The following discussion of our financial condition and results of operations should be read together with the financial statements and the related notes set forth under “Item 8. Financial Statements and Supplementary Data” and the Risk Factors set forth in “Item 1. Business.”


	*Code of Business Conduct and Ethics*

We maintain a code of business conduct and ethics for directors, officers and employees, and will promptly disclose any waivers of the code for directors or executive officers. Our code of business practices addresses conflicts of interest; confidentiality; compliance with laws, rules and regulations (including insider trading laws); and related matters.

Critical Accounting Policies

Our discussion and analysis of financial condition and results of operations is based upon our Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these Consolidated Financial Statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses, and related disclosure. We evaluate, on an ongoing basis, our estimates and judgments, including those related to sales returns, bad debts, excess inventory and purchase commitments, investments, intangible assets, lease losses and restructuring accruals, income taxes, and contingencies. We base our estimates on historical experience and assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates.

We believe the accounting policies described below, among others, are the ones that most frequently require us to make estimates and judgments, and therefore are critical to the understanding of our results of operations:


	•	revenue recognition and allowances;

	•	inventory write-down;

	•	restructuring accruals;


	•	loss contingencies;

	•	impairment losses on investments;

	•	accounting for stock-based compensation; and

	•	accounting for income taxes.


	*Revenue Recognition and Allowances*

We apply the provisions of SOP 97-2, “Software Revenue Recognition” and related interpretations to all revenue transactions. We recognize revenue when:


	•	Persuasive Evidence of an Arrangement Exists. It is our customary practice to have a purchase order prior to recognizing revenue on an arrangement.

	•	Delivery has Occurred. Our product is physically delivered to our customers, generally with standard transfer terms as FOB shipping point. Products shipped with acceptance criteria or return rights are not recognized as revenue until all criteria are achieved. If undelivered products or services exist that are essential to the functionality of the delivered product in an arrangement, delivery is not considered to have occurred.

	•	The Fee is Fixed or Determinable. Arrangements with payment terms extending beyond our standard terms and condition practices are not considered to be fixed or determinable. Revenue from such arrangements is recognized as the fees become due and payable.

	•	Collection is Probable. Probability of collection is assessed on a customer-by-customer basis. Customers are subject to a credit review process that evaluates the customers’ financial position and ultimately their ability to pay. If it is determined from the outset of an arrangement that collection is not probable based upon our review process, revenue is recognized upon cash receipt.

For arrangements with multiple elements, we allocate revenue to each element using the residual method based on vendor specific objective evidence of the undelivered items. We defer the portion of the arrangement fee equal to the fair value of the undelivered elements until they are delivered. Vendor specific objective evidence is based on the price charged when the element is sold separately.

A typical arrangement includes product, software subscription, and maintenance. Some arrangements include training and consulting. Software subscriptions include unspecified product upgrades and enhancements on a when-and-if-available basis, bug fixes, and patch releases, and are included in product revenues. Service maintenance includes contracts for technical support and hardware maintenance. Revenue from software subscriptions and service is recognized ratably over the contractual term, generally one to three years. Revenue from training and consulting is recognized as the services are performed.

We record reductions to revenue for estimated sales returns at the time of shipment. These estimates are based on historical sales returns, changes in customer demand, and other factors. If actual future returns and allowances differ from past experience, additional allowances may be required.


	*Allowance for Doubtful Accounts*

We also maintain a separate allowance for doubtful accounts for estimated losses based on our assessment of the collectibility of specific customer accounts and the aging of the accounts receivable. We analyze accounts receivable and historical bad debts, customer concentrations, customer solvency, current economic and geographic trends, and changes in customer payment terms and practices when evaluating the adequacy of the allowance for doubtful accounts. If the financial condition of our customers deteriorates, resulting in an impairment of their ability to make payments, additional allowances may be required.


	*Inventory Write-down*

We write down inventory and record purchase commitment liabilities for estimated excess and obsolete inventory equal to the difference between the cost of inventory and the estimated fair value based upon assumptions about future demand and market conditions. Although we strive for accuracy in our forecasts of future product demand, any significant unanticipated changes in demand or technological developments could have a significant impact on the value of our inventory and commitments, and our reported results. If actual market conditions are less favorable than those projected, additional write-downs and other charges against earnings may be required. If actual market conditions are more favorable, we may realize higher gross margin in the period when the written-down inventory is sold.

We engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers. We also provide for the estimated cost of known product failures based on known quality issues when they arise. Should actual cost of product failure differ from our estimates, revisions to the estimated liability would be required.


	*Restructuring Accruals*

In fiscal 2002, as a result of continuing unfavorable economic conditions and a reduction in IT spending rates, we implemented two restructuring plans, which included reductions in workforce and a consolidation of facilities. These restructuring accruals were accounted for in accordance with EITF Issue No. 94-3, Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring), and included various assumptions such as the time period over which the facilities will be vacant, expected sublease terms, and expected sublease rates. These estimates are reviewed and revised periodically and may result in a substantial change to restructuring expense should different conditions prevail than were anticipated in original management estimates. See Note 12 to the Condensed Consolidated Financial Statements for further discussion.


	*Loss Contingencies*

We are subject to the possibility of various loss contingencies arising in the ordinary course of business. We consider the likelihood of the loss or impairment of an asset or the incurrence of a liability as well as our ability to reasonably estimate the amount of loss in determining loss contingencies. An estimated loss contingency is accrued when it is probable that a liability has been incurred or an asset has been impaired and the amount of loss can be reasonably estimated. We regularly evaluate current information available to us to determine whether such accruals should be adjusted.


	*Impairment Losses on Investments*

We perform periodic reviews of our investments for impairment. Our investments in publicly held companies are generally considered impaired when a decline in the fair value of an investment as measured by quoted market prices is less than its carrying value, and such a decline is not considered temporary. Our investments in privately held companies are considered impaired when a review of the investees’ operations and other indicators of impairment indicate that the carrying value of the investment is not likely to be recoverable. Such indicators include, but are not limited to, limited capital resources, limited prospects of receiving additional financing, and limited prospects for liquidity of the related securities. In the first quarter of fiscal 2003, we recorded a non-cash, other-than-temporary write-down of $0.7 million related to impairments of our investments in a publicly traded company. In the second quarter of fiscal 2002, we recorded a non-cash, other-than-temporary write-down of $13.0 million related to impairments of our investments in publicly traded and private companies.

Accounting for Stock-based Compensation

We account for stock-based compensation in accordance with the provisions of Accounting Principle Board Opinion No. 25 (“APB” No. 25), Accounting for Stock Issued to Employees, and comply with the disclosure provisions of Statement of Financial Accounting Standards (“SFAS”) No. 123 “Accounting for

Stock-Based Compensation,” as amended by SFAS 148, Accounting for Stock-Based Compensation — Transition and Disclosures. Deferred compensation recognized under APB No. 25 is amortized to expense using the graded vesting method. We account for stock options issued to non-employees in accordance with the provisions of SFAS No. 123 and EITF No. 96-18 under the fair value based method.


	*Accounting for Income Taxes*

The determination of our tax provision is subject to judgments and estimates due to operations in several tax jurisdictions outside the U.S. Earnings derived from our international business are generally taxed at rates that are lower than U.S. rates, resulting in a reduction of our effective tax rate. The ability to maintain our current effective tax rate is contingent upon existing tax laws in both the U.S. and in the respective countries in which our international subsidiaries are located. Future changes in domestic or international tax laws could affect the continued realization of the tax benefits we are currently receiving and expect to receive from international business. In addition, a decrease in the percentage of our total earnings from our international business or in the mix of international business among particular tax jurisdictions could increase our overall effective tax rate. Also, our current effective tax rate assumes that U.S. income taxes are not provided for undistributed earnings of certain non-U.S. subsidiaries. These earnings could become subject to incremental foreign withholding or federal and state income taxes should they be either deemed or actually remitted to the U.S.

The carrying value of our net deferred tax assets, which is made up primarily of income tax deductions, credits, and net operating loss carryforwards resulting from stock option exercises, assumes that we will be able to generate sufficient future income to fully utilize these tax deductions and credits. If we do not generate sufficient future income, the realization of these deferred tax assets may be impaired resulting in additional income tax expense. We have provided a valuation allowance on certain of our deferred tax assets because of uncertainty regarding their realizability due to expectation of future employee stock option exercises.

New Accounting Standards

In June 2002, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities,” which addresses accounting for restructuring and similar costs. SFAS No. 146 supersedes previous accounting guidance, principally EITF Issue No. 94-3. The Company adopted the provisions of SFAS No. 146 for restructuring activities initiated after December 31, 2002. SFAS No. 146 requires that the liability for costs associated with an exit or disposal activity be recognized when the liability is incurred. Under EITF Issue No. 94-3, a liability for an exit cost was recognized at the date of the Company’s commitment to an exit plan. SFAS No. 146 also establishes that the liability should initially be measured and recorded at fair value. Accordingly, SFAS No. 146 may affect the timing of recognizing future restructuring costs as well as the amounts recognized.

In November 2002, the FASB issued Interpretation No. 45, “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others” (“FIN 45”). FIN 45 requires certain guarantees to be recorded at fair value and requires a guarantor to make disclosures, even when the likelihood of making any payments under the guarantee is remote. For those guarantees and indemnifications that do not fall within initial recognition and measurement requirements of FIN 45, the Company must continue to monitor the conditions that are subject to the guarantees and indemnifications, as required under existing generally accepted accounting principles, to identify if a loss has been incurred. If the Company determines that it is probable that a loss has been incurred, any such estimable loss would be recognized. The initial recognition and measurement requirements do not apply to the Company’s product warranties or to the provisions contained in the majority of the Company’s software license agreements that indemnify licensees of the Company’s software from damages and costs resulting from claims alleging that the Company’s software infringes the intellectual property rights of a third party. The Company has provided disclosures for the year ended April 30, 2003 as required by FIN 45 in Note 14 to its consolidated financial statements. The Company does not expect adoption of the liability recognition provisions to have a material impact on its financial position or results of operations.

In December 2002, the EITF reached a consensus on EITF 00-21, “Revenue Arrangements with Multiple Deliverables.” This issue addresses certain aspects of the accounting by a vendor for arrangements under which it will perform multiple revenue-generating activities. In some arrangements, the different revenue-generating activities (deliverables) are sufficiently separable and there exists sufficient evidence of their fair values to separately account for some or all of the deliverables (that is, there are separate units of accounting). In other arrangements, some or all of the deliverables are not independently functional, or there is not sufficient evidence of their fair values to account for them separately. This issue addresses when and, if so, how an arrangement involving multiple deliverables should be divided into separate units of accounting. This issue does not change otherwise applicable revenue recognition criteria. The guidance in this issue is effective for revenue arrangements entered into in fiscal periods beginning after June 15, 2003. The Company does not expect that the adoption of EITF 00-21 will have a material effect on its consolidated financial statements.

In December 2002, the FASB issued SFAS 148, “Accounting for Stock-Based Compensation — Transition and Disclosure, an amendment to FASB Statement 123.” SFAS 148 provides alternative methods of transition for a voluntary change to the fair value based method of accounting of stock-based employee compensation. In addition, SFAS 148 amends the disclosure requirements of SFAS 123, “Accounting for Stock-Based Compensation,” to require prominent disclosures in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. The Company adopted the disclosure provisions of SFAS 148 effective April 30, 2003.

In January 2003, the FASB issued Interpretation No. 46 (“FIN 46”), “Consolidation of Variable Interest Entities.” FIN 46 requires an investor with a majority of the variable interests in a variable interest entity to consolidate the entity and also requires majority and significant variable interest investors to provide certain disclosures. A variable interest entity is an entity in which the equity investors do not have a controlling interest or the equity investment at risk is insufficient to finance the entity’s activities without receiving additional subordinated financial support from the other parties. The Company does not expect to identify any variable interest entities that must be consolidated.

In April 2003, the FASB issued SFAS No. 149, “Amendment of SFAS No. 133 on Derivative Instruments and Hedging Activities.” SFAS No. 149 amends and clarifies accounting for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities under SFAS No. 133. In particular, this Statement clarifies under what circumstances a contract with an initial net investment meets the characteristic of a derivative. It also clarifies when a derivative contains a financing component that warrants special reporting in the statement of cash flows. SFAS No. 149 is generally effective for contracts entered into or modified after June 30, 2003 and is not expected to have an impact on the Company upon adoption.

In May 2003, the FASB has issued SFAS No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity.” The Statement improves the accounting for certain financial instruments that, under previous guidance, issuers could account for as equity. The new Statement requires that those instruments be classified as liabilities in statements of financial position. This statement is effective for interim periods beginning after June 15, 2003. The Company is currently evaluating the effect of this statement on its consolidated financial statement.

Fiscal 2003 Compared to Fiscal 2002

Product revenues — Product revenues increased by 9.9% to $802.3 million in fiscal 2003, from $729.9 million in fiscal 2002. Product revenues growth was across all geographies. This increase in product revenues was specifically attributable to increased software licenses and software subscriptions and an increase in units shipped, as compared to the prior year.

Our revenue growth was primarily driven by new product innovation as we continue to enhance and extend our full-line enterprise portfolio, providing customers with a lower overall cost of ownership. We expanded both our customer base and strategic partnerships with enterprise infrastructure providers and gained market acceptance for our new and expanded unified storage, NearStore and NetCache products. We believe our competitive advantage is a result of lower total cost of ownership from a combination of four factors: lower acquisition cost, reduced administrative overhead, minimized service cost, and reduced downtime of critical business applications.

Product revenues were favorably impacted by the following factors:


	•	increased sales from industry verticals, including energy, telecommunications, financial services, manufacturing, life sciences, and the government;

	•	a higher average selling price for our newer products: FAS960, FAS940, F825 filer, F87 filer, C2100 and C1200 NetCache products, as well as NearStore R100 and R150 nearline storage systems and software features;

	•	data management software offering a unique set of features to enable mission-critical availability, while reducing the complexity of enterprise storage management;

	•	higher sales of software subscription upgrades, representing 8.4% and 6.6% of total revenues for fiscal 2003 and 2002, respectively;

	•	increased revenues from our new product introductions such as: FAS960, FAS940, F825, F810 and F87 filer products; NearStore R100 and R150 systems; and NetCache C2100 and C1200 appliances; and

	•	increased sales through indirect channels, including sales through our OEM partners, representing 46.5% and 39.1% of total revenues for fiscal 2003 and 2002, respectively.

Product revenues were negatively impacted by the following factors:


	•	continued weakness in demand for our products resulting from unfavorable economic conditions and capital spending environment;

	•	continued weakness in technology spending from Internet- and technology-related customers;

	•	decreased cost per megabyte as a result of larger disk capacity; and

	•	declining average selling price and unit sales of our older filer and caching products.

Service revenues — Service revenues, which include hardware support, professional services, and educational services, increased by 31.2% to $89.8 million in fiscal 2003, from $68.5 million in fiscal 2002. Service revenues are generally deferred and, in most cases, recognized ratably over the service period obligations, which are typically one to three years. The increase in service revenues (representing 10.1% and 8.6% of total revenues for fiscal 2003 and 2002, respectively) was due to an increasing number of enterprise customers, who typically purchase more complete service packages. Higher service revenues was also related to a growing installed base resulting in new customer support contracts in addition to support contract renewals by existing customers. While it is an element of our strategy to expand and offer a more comprehensive, global enterprise support and service solution, we cannot assure you that service revenue will grow at the current rate in fiscal 2004.

International total revenues (including U.S. exports) increased by 11.9% for fiscal 2003 as compared to fiscal 2002. International total revenues were $375.2 million, or 42.1% of total revenues for fiscal 2003. The increase in international sales for fiscal 2003 was primarily a result of European and Asia Pacific net revenues growth, driven by larger storage implementations and new products, and positive foreign exchange effects from a weak U.S. dollar, as compared to the prior year.

Product gross margin — Product gross margin increased to 65.1% of product revenues for fiscal 2003 as compared to 63.3% in fiscal 2002. Amortization of existing technology included in cost of product revenue was $5.5 and $5.7 million, respectively, for fiscal 2003 and 2002. For fiscal 2004, estimated future amortization expense is $3.0 million and none thereafter.

Product gross margin was favorably impacted by:


	•	favorable product and add-on software mix;

	•	competitive pricing solutions with our core filer products bundled with software features;

	•	higher average selling prices for our new products;


	•	growth in software subscription upgrades and software licenses due primarily to a larger installed base and an increasing number of new enterprise customers; and

	•	manufacturing cost management.

Product gross margin was negatively impacted by:


	•	increased sales through indirect channels;

	•	higher disk content with an expanded storage capacity for the higher-end products;

	•	sales price reductions due to competitive pricing pressure and selective pricing discounts;

	•	lower average selling price of certain add-on software options.

Service gross margin — Service gross margin increased to 26.5% for fiscal 2003 compared to 18.2% for fiscal 2002. Investments in customer service increased by 17.8% to $66.0 million in fiscal 2003 from $56.0 million in fiscal 2002. The improvement in service gross margin in fiscal 2003 was primarily due to operational and cost efficiencies in the global customer service organizations, combined with the ramping up of our service infrastructure in fiscal 2002 in anticipation of service revenue growth.

Sales and marketing — Sales and marketing expenses consist primarily of salaries, commissions, advertising and promotional expenses, and certain customer service and support costs. Sales and marketing expenses increased 7.0% to $304.2 million for fiscal 2003, from $284.4 million for fiscal 2002. These expenses were 34.2% and 35.6% of total revenues for fiscal 2003 and fiscal 2002, respectively. The increase was attributed to the continued worldwide investment in our sales and customer service organizations associated with selling complete solutions at the enterprise level, marketing and various advertising programs, and expenses associated with our growing mix of enterprise customers and associated global account programs. Sales and marketing headcount decreased to 1,199 in fiscal 2003, from 1,224 in fiscal 2002.

We expect to continue to selectively add sales capacity in an effort to expand domestic and international markets, introduce new products, establish and expand new distribution channels, and increase product and company awareness. We expect to increase our sales and marketing expenses commensurate with future revenue growth.

Research and development — Research and development expenses consist primarily of salaries and benefits, prototype expenses, non-recurring engineering charges, and fees paid to outside consultants. Research and development expenses decreased 3.3% to $112.9 million in fiscal 2003, from $116.7 million in fiscal 2002. These expenses represented 12.7% and 14.6% of total revenues for fiscal 2003 and 2002, respectively. Research and development expenses decreased in absolute dollars, primarily as a result of cost control, reduction in discretionary spending efforts, the impact of fiscal 2002 restructuring activities. Research and development headcount increased to 526 in fiscal 2003, from 514 in fiscal 2002. We expect to continuously support current and future product development and enhancement efforts, and incur prototyping expenses and non-recurring engineering charges associated with the development of new products and technologies.

We believe that our future performance will depend in large part on our ability to maintain and enhance our current product line, develop new products that achieve market acceptance, maintain technological competitiveness, and meet an expanding range of customer requirements. We intend to continuously expand our existing product offerings and introduce new products, and expect that expenditures for these purposes will increase in absolute dollars. For both fiscal 2003 and 2002, no software development costs were capitalized.

General and administrative — General and administrative expenses decreased 8.4% to $36.8 million in fiscal 2003, from $40.2 million in fiscal 2002. These expenses represented 4.1% and 5.1% of total revenues for fiscal 2003 and 2002, respectively. Decreases in absolute dollars were primarily due to cost control, reduction in discretionary spending efforts, the successful collection of previously accrued customer-specific bad debt allowances, partially offset by expenses associated with initiatives to enhance and implement an enterprise-wide ERP system. General and administrative headcount increased to 283 in fiscal 2003 from 246 in fiscal 2002. We believe that our general and administrative expenses will increase in absolute dollars in fiscal 2004 due to the investment in our enterprise-wide ERP system and expanded regulatory requirements.

Amortization of Goodwill — Due to the adoption of SFAS No. 142, goodwill is no longer amortized in fiscal 2003 as compared to amortization expense of $15.2 million in fiscal 2002.

Stock compensation — We account for stock-based employee compensation arrangements in accordance with the provisions of APB No. 25, “Accounting for Stock Issued to Employees,” and comply with the provisions of SFAS No. 123, “Accounting for Stock-Based Compensation,” for non-employee compensation awards. Accordingly, we recognize the intrinsic value for employees and the fair value for non-employees as stock compensation expense over the vesting terms of the awards. Stock compensation expenses were $3.6 million and $7.2 million in fiscal 2003 and 2002, respectively. This decrease was primarily due to $2.2 million of lower deferred stock compensation amortization in fiscal 2003 compared to fiscal 2002 attributed to forfeitures of unvested options assumed in the WebManage acquisition; a decrease of $2.1 million of stock compensation as 165,310 contingently issuable milestone shares relating to Orca valued at $3.0 million were released in fiscal 2002 as compared to the release of 99,186 shares valued at $0.9 million in fiscal 2003; offset by an increase of $0.7 million relating to the fair value of options granted to a member of the Board of Directors. Estimated future deferred stock compensation amortization relating to assumed WebManage unvested options and deferred salary investment options for fiscal 2004 are expected to be $1.2 million. For fiscal 2005, estimated future stock compensation amortization expenses are $0.2 million and none thereafter.

Restructuring charges — In fiscal 2002, as a result of continuing unfavorable economic conditions and a reduction in IT spending rates, we implemented two restructuring plans, which included reductions in workforce and a consolidation of facilities.


	*Fiscal 2002 Second Quarter Restructuring Plan*

In August 2001, we implemented the first restructuring plan, which included a reduction in workforce by approximately 200 employees and a consolidation of facilities. The action was required to properly align and manage the business commensurate with our then current revenue levels. All functional areas of the Company were affected by the reduction. We completed our actions during the second quarter of fiscal 2002. As a result of this restructuring, we incurred a charge of $8.0 million. The restructuring charge included $4.8 million of severance-related amounts, $2.7 million of committed excess facilities and facility closure expenses, and $0.5 million in fixed assets write-offs. The reserve balances of $0.8 million and $0.5 million, respectively, at April 30, 2003 and 2002, were included in other accrued liabilities.

During fiscal 2002, we purchased our Sunnyvale headquarters site and terminated the operating leases. As a result, an adjustment was made to reduce the previously recorded estimated facilities lease losses by $1.5 million. During fiscal 2003, we recorded a net restructuring adjustment of $0.3 million due to changes in the estimated costs of certain actions and final resolution of certain restructuring activities. In the event that the foreign facilities are not subleased, we will be obligated for additional total lease payments of approximately $0.7 million to be payable through January 2006.

The following analysis sets forth the significant components of the restructuring reserve at April 30, 2003 and 2002 (in thousands):


	Severance-			Fixed Assets
	Related Amounts			Write-Off			Facility			Total

Restructuring charge	$	4,796		$	528		$	2,656		$	7,980

Reserve balance at April 30, 2003	$	667		$	—		$	140		$	807


	*Fiscal 2002 Fourth Quarter Restructuring Plan*

In April 2002, we announced and substantially completed a restructuring related to the closure of an engineering facility and consolidation of resources to the Sunnyvale headquarters, which included a headcount reduction of 34 employees. As a result of this restructuring, we incurred a charge of $5.9 million. The restructuring charge included $0.8 million of severance-related amounts, $4.6 million of committed excess facilities and facility closure expenses, and $0.5 million in fixed assets write-off. Of the reserve balance at April 30, 2003, $1.5 million was included in other accrued liabilities and the remaining $3.1 million was classified as long-term obligations.

In January 2003, we updated our assumptions and estimates based on certain triggering events, which resulted in an additional net charge of $0.9 million, primarily relating to our engineering facility lease. Our estimates are reviewed and revised periodically and may result in a substantial charge to restructuring expense should different conditions prevail than were anticipated in original management estimates. Such estimates included various assumptions such as the time period over which the facilities will be vacant, expected sublease terms, and expected sublease rates. In the event that the engineering facility is not subleased, we will be obligated for additional total lease payments of $3.4 million to be payable through November 2010.

The following analysis sets forth the significant components of the restructuring reserve at April 30, 2003 and 2002 (in thousands):


	Severance-			Fixed Assets
	Related Amounts			Write-Off			Facility			Total

Restructuring charge	$	813		$	473		$	4,564		$	5,850
Cash payments		(629	)		—			(32	)		(661	)
Non-cash portion		—			(473	)		—			(473	)

Non-cash portion		—			—			—			—
Adjustments		(107	)		—			1,030			923

Reserve balance at April 30, 2003	$	—		$	—		$	4,571		$	4,571

Of the reserve balances at April 30, 2003 and 2002, $1.5 million and $1.1 million, respectively were included in other accrued liabilities and the remaining $3.1 million and $3.7 million, respectively, were classified as long-term obligations.

Interest income — During fiscal 2003, interest income was $12.2 million, as compared to $18.5 million in fiscal 2002. The decrease in interest income was primarily due to lower average interest rates, partially offset by higher investment balances provided by operating activities. We expect interest income to decline further in fiscal 2004, as existing investments mature and proceeds are reinvested in a lower interest-rate environment.

Other income (expense), net — Other income (expense), net, included a net exchange loss from foreign currency transactions of $1.0 million and $1.8 million, respectively, for fiscal 2003 and 2002.

Net loss on investments — Our investments in publicly held companies are generally considered impaired when a decline in the fair value of an investment as measured by quoted market prices is less than its carrying value, and such a decline is not considered temporary. In fiscal 2003, we recorded a noncash, other-than-temporary write-down of $0.7 million related to the impairment of our investment in a publicly traded company. In fiscal 2002, we recorded a noncash, other-than-temporary write-down of $13.0 million related to impairments of our investments in publicly traded and private companies. During fiscal 2003, we sold shares of certain privately held investments and realized a net loss of $0.5 million. During fiscal 2002, we sold shares of certain marketable investments and the realized gain was not material.

Gain on sale of intangible assets — We recorded a gain on sale of intangible assets of $0.6 million in fiscal 2003 related to the sale of our ContentReporter^TM software. We intend to resell this software through a licensing arrangement.

Provision (benefit), for income taxes — For fiscal 2003, our effective tax rate was 21.8%. The effective tax rate for fiscal 2003 differed from the U.S. statutory rate primarily due to credits, and foreign earnings in a lower tax jurisdiction. For fiscal 2002, we applied an annual benefit rate of 19.7% to pretax loss. Our effective tax rate is based on existing tax laws and distributions of income/(loss) among different entities and tax jurisdictions.

Fiscal 2002 Compared to Fiscal 2001

Product revenues — Product revenues decreased by 23.8% to $729.9 million in fiscal 2002, from $957.8 million in fiscal 2001. The decline in product revenues was due to a decrease in product sales to Internet-based companies and reduced capital spending among technology companies across all geographies, but primarily in North America. This decrease in product revenues for fiscal 2002 was specifically attributable to a lower volume of units and software licenses shipped, as compared to fiscal 2001.

Product revenues were negatively impacted by the following factors:


	•	reduced demand for our products resulting from deteriorating macroeconomic conditions;

	•	continued weakness in technology spending from Internet- and technology-related customers;

	•	decreased sales through indirect channels, including sales through our OEM partners, representing 39.1% and 28.2% of total revenues for fiscal 2002 and 2001, respectively;

	•	declining average selling price of the F700 filers and older caching products; and

	•	declining unit sales of our older products.

Product revenues were favorably impacted by the following factors:


	•	increased sales from new industry verticals: energy, telecommunications, financial services, manufacturing, life sciences and the government;

	•	a higher average selling price of our new products: our high-end F880 and low-end F87 filer products, as well as new NetCache appliances and software features;

	•	competitive pricing advantage as a result of lower total cost of ownership in four aspects: lower acquisition cost, reduced administrative overhead, minimized service cost and reduced downtime of critical business applications;


	•	data management and content delivery software offering a unique set of features to ensure mission-critical availability, while reducing the complexity of enterprise storage management;

	•	higher sales of software subscription upgrades, representing 6.6% and 3.6% of total revenues for fiscal 2002 and 2001, respectively;

	•	increased add-on software revenue from multiprotocol solutions; and

	•	introduction of NearStore systems for business continuance and online recovery.

Service revenues — Service revenues increased by 41.6% to $68.5 million in fiscal 2002, from $48.4 million in fiscal 2001. Service revenue is generally deferred and, in most cases, recognized ratably over the service period obligations, which are typically one to three years. The increase in service revenues (representing 8.6% and 4.8% of total revenues for fiscal 2002 and 2001, respectively) was primarily related to a growing installed base resulting in new customer support contracts in addition to support contract renewals by existing customers.

International total revenues (including U.S. exports) decreased by 12.4% for fiscal 2002 as compared to fiscal 2001. International total revenues were $335.2 million, or 42.0% of total revenues for fiscal 2002. The decline in international sales for fiscal 2002 was primarily a result of a slower demand in the Europe and Asia Pacific markets offset by our increased sales and marketing efforts internationally.

Product gross margin — Product gross margin decreased to 63.3% of product revenues for fiscal 2002 as compared to 64.0% in fiscal 2001. Amortization of existing technology included in cost of product revenue was $5.7 and $2.6 million, respectively, for fiscal 2002 and 2001.

Product gross margin was negatively impacted by:


	•	the decrease in product sales volume;

	•	sales price reductions due to competitive pricing pressure and selective pricing discounts;

	•	lower of cost or market adjustments to inventory;

	•	decreased licensing of our software due to lower volume of units shipped;

	•	lower average selling price of certain add-on software options; and

	•	higher disk content with an expanded storage capacity for the higher-end filers including the F840 and F880 filers.

Product gross margin was favorably impacted by:


	•	lower costs of key components and subsystems;

	•	favorable product and software mix;

	•	a faster-than-expected shift to our new high-density storage subsystem due to a favorable average selling price on the enclosures, electronics and power systems sold with the disk systems, and efficient hardware packaging;

	•	higher average selling prices for our new products;

	•	manufacturing overhead cost control and reduction efforts, including the restructuring impact;

	•	December and July partial facility shutdowns; and

	•	growth in software subscription upgrades due primarily to a larger installed base.

Service gross margin — Service gross margin increased to 18.2% for fiscal 2002 as compared to a negative gross margin of 23.8% in fiscal 2001. Investments in customer service decreased by 6.5% to $56.0 million in fiscal 2002, from $59.9 million in fiscal 2001. The improvement in service gross margin in fiscal 2002 was primarily due to operational and cost efficiencies in the global customer service organizations. The negative

service gross margin in fiscal 2001 was due to the ramping up and continued investment in our service infrastructure in anticipation of service revenue growth.

Sales and marketing — Sales and marketing expenses consist primarily of salaries, commissions, advertising and promotional expenses, and certain customer service and support costs. Sales and marketing expenses decreased 1.6% to $284.4 million for fiscal 2002, from $289.0 million for fiscal 2001. These expenses were 35.6% and 28.7% of total revenues for fiscal 2002 and fiscal 2001, respectively. The decrease in absolute dollars was attributed to various cost control and reduction measures, restructuring impact, lower commission expenses and other profit-dependent payroll-related expenses, and disposal of certain capital assets in fiscal 2001, partially offset by the continued worldwide investment in our sales and customer service organizations. Sales and marketing headcount decreased to 1,224 in fiscal 2002, from 1,277 in fiscal 2001 due primarily to the restructuring impact.

Research and development — Research and development expenses consist primarily of salaries and benefits, prototype expenses, non-recurring engineering charges, and fees paid to outside consultants. Research and development expenses decreased 3.5% to $116.7 million in fiscal 2002, from $120.9 million in fiscal 2001. These expenses represented 14.6% and 12.0% of total revenues for fiscal 2002 and 2001, respectively. Research and development expenses decreased in absolute dollars, primarily as a result of cost control, reduction in discretionary spending efforts, restructuring impact, the two holiday facility shutdowns, lower headcount, and lower profit-dependent payroll related expenses, partially offset by the operating impact of the Orca and WebManage acquisitions. Research and development headcount decreased to 514 in fiscal 2002, from 566 in fiscal 2001.

General and administrative — General and administrative expenses decreased 0.1% to $40.2 million in fiscal 2002, from $40.2 million in fiscal 2001. These expenses represented 5.0% and 4.0% of total revenues for fiscal 2002 and 2001, respectively. Decreases in absolute dollars were primarily due to cost controls, reductions in discretionary spending, the impact of restructuring, the two holiday facility shutdowns, and lower profit-dependent payroll related expenses, partially offset by expenses associated with initiatives to enhance enterprise-wide management information systems, general legal costs, and an increase in the allowance for bad debts. General and administrative headcount decreased to 246 in fiscal 2002, from 253 in fiscal 2001.

Amortization of Goodwill — Due to the adoption of SFAS No. 142, goodwill is no longer amortized in fiscal 2003 as compared to amortization expense of $15.2 million in fiscal 2002 and $9.1 million in fiscal 2001.

In-process research and development — We incurred in-process research and development charges of approximately $26.7 million in the first quarter of fiscal 2001 related to the acquisition of Orca. The purchase price of the transaction was allocated to the acquired assets and liabilities based on their estimated fair values as of the date of the acquisition. Approximately $26.7 million was allocated to in-process research and development and charged to operations, because the acquired technology had not reached technological feasibility and had no alternative uses. The value was determined by estimating the costs to develop the acquired in-process technology into commercially viable products, estimating the resulting net cash flows from such projects, and discounting the net cash flows back to their present value. The discount rate included a factor that took into account the uncertainty surrounding the successful development of the acquired in-process technology. These estimates are subject to change, given the uncertainties of the development process, and no assurance can be given that deviations from these estimates will not occur.

The Orca acquisition has been successfully utilized for the design and development of the DAFS protocol. By eliminating much of the traditional operating system overhead, DAFS allows for improved I/O performance while using fewer CPU cycles. The protocol leverages next generation networking technologies that provide remote memory transfer capabilities, including Remote Direct Memory Access (“RDMA”) implemented in Virtual Interface (“VI”) and Infiniband. The DAFS protocol has good industry support and is now under consideration as an industry standard. We introduced DAFS capable products in April 2002.

provisions of SFAS No. 123, “Accounting for Stock-Based Compensation,” for non-employee compensation awards. Accordingly, we recognize the intrinsic value for employees and the fair value for non-employees as stock compensation expense over the vesting terms of the awards. Stock compensation expenses were $7.2 million and $6.2 million in fiscal 2002 and 2001, respectively. This increase was primarily attributable to the recognition of stock compensation on options assumed in the WebManage acquisition and the release of 165,310 contingently issuable milestone shares relating to Orca valued at $3.0 million.

Restructuring charges — In August 2001, we implemented a restructuring plan, which included a reduction in workforce by approximately 200 employees and a consolidation of facilities. The action was required to properly align and manage the business commensurate with our then-current revenue levels. All functional areas of the Company were affected by the reduction. We completed our actions during the second quarter of fiscal 2002. As a result of this restructuring, we incurred a charge of $8.0 million. The restructuring charge included $4.8 million of severance-related amounts, $2.7 million of committed excess facilities and facility closure expenses, and $0.5 million in fixed assets write-offs.

During the fourth quarter of fiscal 2002, we purchased our Sunnyvale headquarters site and terminated the operating leases. As a result, an adjustment was made to reduce the previously recorded estimated facilities lease losses by $1.5 million.

As of April 30, 2002, we had paid substantially all of the severance liability. Of the balance at April 30, 2002, $0.5 million was included in other accrued liabilities.

The following analysis sets forth the significant components of the second quarter fiscal 2002 restructuring at April 30, 2002 (in thousands):


	Severance-			Fixed Assets
	Related Amounts			Write-Off			Facility			Total

Restructuring charge	$	4,796		$	528		$	2,656		$	7,980

In April 2002, we announced and substantially completed a restructuring related to the closure of an engineering facility and consolidation of resources to the Sunnyvale headquarters, which included a headcount reduction of 34 employees. As a result of this restructuring, we incurred a charge of $5.9 million. The restructuring charge included $0.8 million of severance-related amounts, $4.6 million of committed excess facilities and facility closure expenses, and $0.5 million in fixed assets write-offs. Of the reserve balance at April 30, 2002, $1.1 million was included in other accrued liabilities and the remaining $3.6 million was classified as long-term obligations.

The following analysis sets forth the significant components of the fourth quarter fiscal 2002 restructuring at April 30, 2002 (in thousands):


	Severance-			Fixed Assets
	Related Amounts			Write-Off			Facility			Total

Restructuring charge	$	813		$	473		$	4,564		$	5,850
Cash payments		(629	)		—			(32	)		(661	)
Non-cash portion		—			(473	)		—			(473	)

Reserve balance at April 30, 2002	$	184		$	—		$	4,532		$	4,716

Interest income and other, net — During fiscal 2002, interest income and other, net was $16.6 million, as compared to $23.4 million in fiscal 2001. The decrease in interest income was primarily due to lower average interest rates, partially offset by higher average investment balances from cash, short-term investments and

restricted cash generated from operations. Interest income and other, net also included gains and losses from foreign currency transactions.

Net loss on investments — We perform periodic reviews of our investments for impairment. Our investments in publicly held companies are generally considered impaired when a decline in the fair value of an investment as measured by quoted market prices is less than its carrying value, and such a decline is not considered temporary. Our investments in privately held companies are considered impaired when a review of the investees’ operations and other indicators of impairment indicate that the carrying value of the investment is not likely to be recoverable. Such indicators include, but are not limited to, limited capital resources, limited prospects of receiving additional financing, and limited prospects for liquidity of the related securities. In the second quarter of fiscal 2002, we recorded a noncash, other-than-temporary write-down of $13.0 million related to impairments of our investments in publicly traded and private companies. During fiscal 2002 and 2001, we sold shares of certain marketable equity securities and the realized gains for those periods were not material.

Provision (benefit), for income taxes — For fiscal 2002, we applied an annual benefit rate of 19.7% to pretax loss. For fiscal 2001, our effective tax rate was 34.5%, which excluded the effect of non-deductible amortization of goodwill and the write-off of acquired in-process research and development. Our effective tax rate is based on existing tax laws and distributions of income/(loss) among different entities and tax jurisdictions.

Liquidity and Capital Resources

As of April 30, 2003, as compared to the April 30, 2002 balances, our cash, cash equivalents, and short-term investments increased by $164.7 million to $618.8 million. We derive our liquidity and capital resources primarily from our cash flow from operations and from working capital. Working capital increased by $124.9 million to $588.5 million as of April 30, 2003, compared to $463.6 million as of April 30, 2002. We generated cash from operating activities totaling $195.3 million and $143.9 million in fiscal 2003 and 2002, respectively. Net cash provided by operating activities in fiscal 2003 was principally related to net income of $76.5 million, increases in other accrued liabilities, accrued compensation and related benefits, income taxes payable, deferred revenue, coupled with depreciation, net loss on investments, amortization of intangible assets and stock compensation, partially offset by decreased accounts payable, and increases in accounts receivable, inventories, deferred income taxes and prepaid expenses and other assets.

We used $61.3 million and $284.2 million of cash in fiscal 2003 and 2002, respectively, for capital expenditures. The fiscal 2002 property and equipment expenditure included the purchase of the land and buildings at our Sunnyvale headquarters site for $249.8 million. Excluding the Sunnyvale headquarters land and buildings acquisition, the increase in capital purchases year over year was primarily attributed to upgrades of our ERP infrastructure, computer-related purchases, and building improvements. We used net proceeds of $90.0 million and $149.9 million in fiscal 2003 and 2002, respectively, for net purchases of short-term investments. Investing activities in fiscal 2003 and 2002 also included new investments in privately-held companies of $0.7 million and $1.1 million, respectively. During fiscal 2003, we sold certain privately held investments and received proceeds of $0.8 million.

We received $29.2 million and $230.2 million in fiscal 2003 and 2002, respectively, from financing activities. The change in cash flow from financing in fiscal 2002 included the effects of a decrease in restricted cash requirements of $193.7 million. This requirement was eliminated in April 2002 in conjunction with the purchase of our Sunnyvale headquarters and termination of our operating leases, and thus had no effect on cash flows from financing activities in fiscal 2003. The decrease in cash flow from financing activities was also a result of lower proceeds from stock option exercises as a result of the decline in our stock price.

Our capital and liquidity requirements depend on numerous factors, including risks relating to fluctuating operating results, continued growth in the network storage and content delivery markets, customer and market acceptance of our products, dependence on new products, rapid technological change, dependence on qualified technical and sales personnel, risk inherent in our international operations, competition, reliance on a limited number of suppliers and contract manufacturers, relationships with strategic partners, dependence on

proprietary technology, intellectual property rights, the value of our investments in equity securities and real estate, and other factors. We believe that our existing liquidity and capital resources are sufficient to fund our operations for at least the next twelve months.

Item 7a. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk related to fluctuations in interest rates, market prices and foreign currency exchange rates. We use certain derivative financial instruments to manage these risks. We do not use derivative financial instruments for speculative or trading purposes. All financial instruments are used in accordance with management-approved policies.

Market Interest and Interest Income Risk

Interest and Investment Income — As of April 30, 2003, we had short-term investments of $334.7 million. Our investment portfolio primarily consists of highly liquid investments with original maturities at the date of purchase of greater than three months, which are classified as available-for-sale, and investment in marketable equity securities in primarily technology companies. These highly liquid investments, consisting primarily of government and corporate debt securities, are subject to interest rate and interest income risk and will decrease in value if market interest rates increase. A hypothetical 10% increase in market interest rates from levels at April 30, 2003, would cause the fair value of these short-term investments to decline by approximately $0.7 million. Because we have the ability to hold these investments until maturity we would not expect any significant decline in value of our investments caused by market interest rate changes. Declines in interest rates over time will, however, reduce our interest income. We do not use derivative financial instruments in our investment portfolio.

Market Price Risk

Equity Securities — We are also exposed to market price risk on our equity securities included in our short-term investments, which are primarily in publicly traded companies in the volatile high-technology industry sector. In fiscal 2003, we recorded a non-cash, other-than-temporary write-down of $0.7 million related to the impairment of our investment in a publicly traded company. In fiscal 2002, we recorded a noncash, other-than-temporary write-down of $13.0 million related to impairments in publicly traded and private companies.

We do not attempt to reduce or eliminate our market exposure on these securities and, as a result, the amount of income and cash flow that we ultimately realize from our investment in future periods may vary materially from the current fair value. A 50% adverse change in the equity price would result in an approximate $0.1 million decrease in the fair value of our equity security as of April 30, 2003.

The hypothetical changes and assumptions discussed above will be different from what actually occurs in the future. Furthermore, such computations do not anticipate actions that may be taken by management,

should the hypothetical market changes actually occur over time. As a result, the effect on actual earnings in the future will differ from those described above.

Foreign Currency Exchange Rate Risk and Foreign Exchange Forward Contracts

We hedge risks associated with foreign currency transactions in order to minimize the impact of changes in foreign currency exchange rates on earnings. We utilize forward contracts to hedge against the short-term impact of foreign currency fluctuations on certain assets and liabilities denominated in foreign currencies. All balance sheet hedges are marked to market through earnings every period. We also use foreign exchange forward contracts to hedge foreign currency forecasted transactions related to certain sales and operating expenses. These derivatives are designated as cash flow hedges under SFAS 133. For cash flow hedges, the gains or losses were included in other comprehensive income and were not material at April 30, 2003.

We do not enter into foreign exchange contracts for speculative or trading purposes. In entering into forward foreign exchange contracts, we have assumed the risk that might arise from the possible inability of counterparties to meet the terms of their contracts. We attempt to limit our exposure to credit risk by executing foreign contracts with credit worthy multinational commercial banks. All contracts have a maturity of less than one year.

2.	Significant Accounting Policies

Fiscal Year — We operate on a 52-week or 53-week year ending on the last Friday in April. For presentation purposes we have indicated in the accompanying consolidated financial statements that our fiscal year end is April 30. Fiscal 2003, 2002 and 2001 were 52-week fiscal years.

Basis of Presentation — The consolidated financial statements include the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions are eliminated in consolidation. Certain amounts from prior years have been reclassified to conform to current-year presentation. These reclassifications did not change previously reported total assets, liabilities, stockholders’ equity or net income.

Cash and Cash Equivalents — We consider all highly liquid debt investments with original maturities of three months or less to be cash equivalents.

Short-Term Investments — Available-for-sale investments with original maturities of greater than three months are classified as short-term investments, as these investments generally consist of highly marketable securities that are intended to be available to meet current cash requirements. All of our investments are classified as available-for-sale, which are carried at fair market value, and unrealized gains or losses recorded in accumulated other comprehensive loss, which is a separate component of stockholders’ equity, net of taxes. Any gains or losses on sales of investments are computed based upon specific identification. For all periods presented, realized gains and losses on available-for-sale investments were not material. Management determines the appropriate classification of debt and equity securities at the time of purchase and reevaluates the classification at each reporting date. Available-for-sale investments are reviewed for evidence of reductions in market value that are other than temporary. We perform periodic reviews of our investments for impairment. Our investments in publicly held companies are generally considered impaired when a decline in the fair value of an investment as measured by quoted market prices is less than its carrying value and such a decline is not considered temporary. During fiscal 2003 and 2002, we recorded a noncash, other-than-temporary write-down of $726 and $3,641, respectively, related to impairment of our investments in publicly traded companies. These write-downs are included in net loss on investments on the income statement. No write-downs were recorded during fiscal 2001.

Investments in Nonpublic Companies — We have certain investments in nonpublicly traded companies in which we have less than 20% of the voting rights and in which we do not exercise significant influence. As of April 30, 2003 and 2002, $909 and $1,724 of these investments are included in other long-term assets on the balance sheet and are carried at cost. We perform periodic reviews of our investments for impairment. Our investments in privately held companies are considered impaired when a review of the investees’ operations and other indicators of impairment indicate that the carrying value of the investment is not likely to be recoverable. Such indicators include, but are not limited to, limited capital resources, limited prospects of

NETWORK APPLIANCE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

receiving additional financing, and limited prospects for liquidity of the related securities. During fiscal 2002, we recorded a noncash, other-than-temporary write-down of $9,367 related to impairments of our investments in private companies. No write-downs were recorded during fiscal 2003 and 2001. During fiscal 2003, we sold shares of certain privately held investments and realized a net loss of $503.

Inventories — Inventories are stated at the lower of cost (first-in, first-out basis) or market.

Property and Equipment — Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which generally range from three to five years. The land at the Sunnyvale headquarters site acquired in April 2002 is not being depreciated. Leasehold improvements are amortized over the shorter of the estimated useful lives of the assets or the remaining term of the lease. Building improvements are amortized over the estimated lives of the assets, which generally range from ten to forty years. Construction in progress will be amortized over the estimated useful lives of the respective assets when they are ready for their intended use.

We review the carrying values of long-lived assets whenever events and circumstances indicate that the net book value of an asset may not be recovered through expected future cash flows from its use and eventual disposition. The amount of impairment loss, if any, is measured as the difference between the net book value and the estimated fair value of the asset.

Goodwill and Purchased Intangible Assets — Goodwill and purchased intangible assets include goodwill and other intangible assets such as existing workforce and existing technology, which are carried at cost less accumulated amortization. For business combinations consummated before July 1, 2001, goodwill and existing workforce were amortized through April 30, 2002 using the straight-line method over an estimated useful life of three to five years. Amortization of other purchased intangibles is computed using the straight-line method over the expected useful life of three to five years. We evaluate the impairment of goodwill and purchased intangible assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. See Note 13 — Goodwill and Purchased Intangible Assets.

Revenue Recognition and Allowance — We apply the provisions of SOP 97-2, “Software Revenue Recognition,” and related interpretations to all revenue transactions. We recognize revenue when:


	•	Persuasive Evidence of an Arrangement Exists. It is our customary practice to have a purchase order prior to recognizing revenue on an arrangement.

	•	Delivery has Occurred. Our product is physically delivered to our customers, generally with standard transfer terms as FOB shipping point. Products shipped with acceptance criteria or return rights are not recognized as revenue until all criteria are achieved. If undelivered products or services exist that are essential to the functionality of the delivered product in an arrangement, delivery is not considered to have occurred.

	•	The Fee is Fixed or Determinable. Arrangements with payment terms extending beyond our standard terms and condition practices are not considered to be fixed or determinable. Revenue from such arrangements is recognized as the fees become due and payable.

	•	Collection is Probable. Probability of collection is assessed on a customer-by-customer basis. Customers are subjected to a credit review process that evaluates the customers’ financial position and ultimately their ability to pay. If it is determined from the outset of an arrangement that collection is not probable based upon our review process, revenue is recognized upon cash receipt.

NETWORK APPLIANCE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The following table presents the components of revenues, stated as a percentage of total revenues:



			Years Ended April 30,

			2003			2002			2001

Revenues:
	Products			81.5	%		84.8	%		91.6	%
	Software subscriptions			8.4	%		6.6	%		3.6	%

		Product revenue		89.9	%		91.4	%		95.2	%
	Service revenue			10.1	%		8.6	%		4.8	%

Total revenues				100.0	%		100.0	%		100.0	%

We also maintain a separate allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. We analyze accounts receivable and historical bad debts, customer concentrations, customer solvency, current economic and geographic trends, and changes in customer payment terms and practices when evaluating the adequacy of the allowance for doubtful accounts. If the financial condition of our customers deteriorates, resulting in an impairment of their ability to make payments, additional allowances may be required.

Software Development Costs — The costs for the development of new software products and substantial enhancements to existing software products are expensed as incurred until technological feasibility has been established, at which time any additional costs would be capitalized in accordance with SFAS No. 86, “Accounting for the Costs of Software to be Sold, Leased, or Otherwise Marketed.” Because we believe our current process for developing software is essentially completed concurrently with the establishment of technological feasibility, which occurs upon the completion of a working model, no costs have been capitalized for any of the periods presented. In accordance with SOP 98-1, “Accounting for the Costs of Computer Software Developed or Obtained for Internal Use,” the cost of internally-developed software is capitalized and included in property and equipment at the point at which the conceptual formulation, design and testing of possible software project alternatives have been completed and management authorizes and commits to funding the project. Pilot projects and projects where expected future economic benefits are less than probable are not capitalized. Internally-developed software costs include the cost of software tools and licenses used in the development of our systems, as well as consulting costs. Completed projects are transferred to property and equipment at cost and are amortized on a straight-line basis over their estimated useful lives, generally three years.

Foreign Currency Translation — For subsidiaries whose functional currency is the local currency, gains and losses resulting from translation of these foreign currency financial statements into U.S. dollars are recorded within stockholders’ equity as part of accumulated other comprehensive loss. For subsidiaries where the functional currency is the U.S. dollar, gains and losses resulting from the process of remeasuring foreign currency financial statements into U.S. dollars are included in other income.

NETWORK APPLIANCE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

In fiscal 2002, we determined that the functional currency of one of our subsidiaries had changed from the Euro to the U.S. Dollar. Accordingly, all monetary assets and liabilities were translated at the current exchange rate in effect as of the balance sheet date, nonmonetary assets and liabilities were translated at historical rates, and total revenues and expenses were translated at average exchange rates in effect during the period. Transaction gains and losses are included in other income (expense) in the accompanying consolidated statements of operations.

Derivative Instruments — We adopted SFAS 133, “Accounting for Derivative Instruments and Hedging Activities.” Derivatives that are not designated as hedges are adjusted to fair value through earnings. If the derivative is designated as a hedge, depending on the nature of the exposure being hedged, changes in fair value will either be offset against the change in fair value of the hedged asset or liability through earnings, or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of the hedge is recognized in earnings immediately. The adoption of this accounting standard did not have a significant impact on our financial position, results of operations, or cash flow.

As a result of our significant international operations, we are subject to risks associated with fluctuating exchange rates. We use derivative financial instruments, principally currency forward contracts, to attempt to minimize the impact of exchange rate movements on our balance sheet relating to certain foreign currency assets and liabilities and operating results. We do not enter into derivative financial instruments for speculative or trading purposes. Currently, we do not enter into any foreign exchange forward contracts to hedge exposures related to firm commitments or equity investments. Our major foreign currency exchange exposures and related hedging programs are described below:

Balance Sheet. We utilize currency forward contracts to hedge currency exchange rate fluctuations related to certain foreign currency assets and liabilities. Gains and losses on these undesignated derivatives offset gains and losses on the assets and liabilities being hedged and the net amount is included in earnings. In fiscal 2003, net gains generated by hedged assets and liabilities totaled $9,910, which were offset by losses on the related derivative instruments of $10,932. In fiscal 2002, net gains generated by hedged assets and liabilities totaled $1,684, which were offset by losses on the related derivative instruments of $3,485. In fiscal 2001, net losses generated by hedged assets and liabilities totaled $2,250, which were offset by gains on the related derivative instruments of $3,898.

Forecasted transactions. We use currency forward contracts to hedge exposures related to forecasted sales and operating expenses denominated in Euros and British Pounds. These contracts are designated as cash flow hedges when the transactions are forecasted and in general closely match the underlying forecasted transactions in duration. The contracts are carried on the balance sheet at fair value and the effective portion of the contracts’ gains and losses is recorded as other comprehensive income until the forecasted transaction occurs.

If the underlying forecasted transactions do not occur, or it becomes probable that they will not occur, the gain or loss on the related cash flow hedge is recognized immediately in other income. During fiscal 2003, we did not record any gains or losses related to forecasted transactions that did not occur or became improbable.

We measure the effectiveness of hedges of forecasted transactions on at least a quarterly basis by comparing the fair values of the designated currency forward contracts with the fair values of the forecasted transactions. No ineffectiveness was recognized in earnings during fiscal 2003.

Use of Estimates — The preparation of the consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to establish accounting policies which contain estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

NETWORK APPLIANCE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Concentration of Credit Risk — Financial instruments which potentially subject us to concentrations of credit risk consist primarily of cash equivalents, short-term investments, and accounts receivable. Cash, cash equivalents, and short-term investments consist primarily of U.S. government agencies, corporate bonds, and municipal bonds, cash accounts held at various banks, and money market funds held at several financial institutions. We sell our products primarily to large organizations in different industries and geographies. Credit risk is mitigated by our credit evaluation process and limited payment terms. We do not require collateral or other security to support accounts receivable. In addition, we maintain an allowance for potential credit losses. In entering into forward foreign exchange contracts, we have assumed the risk that might arise from the possible inability of counterparties to meet the terms of their contracts. The counterparties to these contracts are major multinational commercial banks, and we do not expect any losses as a result of counterparty defaults.

Comprehensive Income — Comprehensive income is defined as the change in equity during a period from non-owner sources. Comprehensive income for the years ending April 30, 2003, 2002, and 2001 has been disclosed within the consolidated statement of stockholders’ equity and comprehensive income.

The components of accumulated other comprehensive loss at April 30, were as follows:


	2003			2002			2001

Accumulated translation adjustments, net		(1,238	)		(2,202	)		(3,317	)

Total accumulated other comprehensive loss		(96	)		(2,366	)		(4,735	)

Net Income per Share — Basic net income per share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for that period. Diluted net income per share is computed giving effect to all dilutive potential shares that were outstanding during the period. Dilutive potential common shares consist of incremental common shares subject to repurchase and common shares issuable upon exercise of stock options.

At April 30, 2003, 2002, and 2001, 44,582, 30,991, and 18,005 shares of common stock options with a weighted average exercise price of $30.98, $40.17, and $59.45 respectively, were excluded from the diluted net income per share computation, as their exercise prices were greater than the average market price of the common shares for the periods.

Stock-Based Compensation — We account for stock-based compensation in accordance with the provisions of APB No. 25, Accounting for Stock Issued to Employees, and comply with the disclosure provisions of SFAS No. 123 as amended by SFAS 148, Accounting for Stock-Based Compensation — Transition and Disclosures. Deferred compensation recognized under APB No. 25 is amortized to expense using the graded vesting method. We account for stock options issued to non-employees in accordance with the provisions of SFAS No. 123 and EITF No. 96-18 under the fair value based method.

We adopted the disclosure-only provisions of SFAS 123, and accordingly, no expense has been recognized for options granted to employees under the various Plans. We amortize deferred stock-based compensation on the graded vesting method over the vesting periods of the applicable stock purchase rights and stock options, generally four years. The graded vesting method provides for vesting of portions of the overall awards at interim dates and results in greater vesting in earlier years than the straight-line method. Had compensation expense been determined based on the fair value at the grant date for awards, consistent with

NETWORK APPLIANCE, INC.

the provisions of SFAS 123, the Company’s pro forma net loss and net loss per share would be as follows (in thousands, except per share data):

Basic and diluted net loss per share, pro forma			$	(0.28	)	$	(0.78	)	$	(0.46	)

During the preparation of the Company’s fiscal 2003 consolidated financial statements, management determined that the pro forma net loss and the pro forma net loss per share for fiscal 2002 and 2001 (for purposes of recording compensation for stock-based awards to employees under SFAS 123 for disclosure purposes) did not include the add-back of the APB 25 stock compensation expense and accordingly such amounts have been reflected. These changes did not impact the Company’s consolidated balance sheet, consolidated statements of income, consolidated statements of stockholders’ equity and comprehensive income and consolidated statements of cash flow for any of the periods presented.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model, and is not subject to revaluation as a result of subsequent stock price fluctuations. The following weighted-average assumptions are used:



	Employee									Employee
	Stock Option Plans									Stock Purchase Plan

	Years Ended April 30,									Years Ended April 30,

	2003			2002			2001			2003			2002			2001

Volatility		76%- 79	%		92	%		80	%		76%- 79	%		92	%		80	%
Expected dividend		—			—			—			—			—			—

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. We use projected volatility rates, which are based upon historical volatility rates since our initial public offering, trended into future years. Because our 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 our options.

Recently Issued Accounting Standards — In June 2002, FASB issued SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities,” which addresses accounting for restructuring and similar costs. SFAS No. 146 supersedes previous accounting guidance, principally EITF Issue No. 94-3. The Company adopted the provisions of SFAS No. 146 for restructuring activities initiated after December 31, 2002. SFAS No. 146 requires that the liability for costs associated with an exit or disposal activity be recognized when the liability is incurred. Under EITF Issue No. 94-3, a liability for an exit cost was recognized at the date of the Company’s commitment to an exit plan. SFAS No. 146 also establishes that the liability should initially be measured and recorded at fair value. Accordingly, SFAS No. 146 may affect the timing of recognizing future restructuring costs as well as the amounts recognized.

so, how an arrangement involving multiple deliverables should be divided into separate units of accounting. This issue does not change otherwise applicable revenue recognition criteria. The guidance in this issue is effective for revenue arrangements entered into in fiscal periods beginning after June 15, 2003. The Company does not expect that the adoption of EITF 00-21 will have a material effect on its consolidated financial statements.

In December 2002, the FASB issued SFAS 148, “Accounting for Stock-Based Compensation — Transition and Disclosure, an amendment to FASB Statement 123.” SFAS 148 provides alternative methods of transition for a voluntary change to the fair value based method of accounting of stock-based employee compensation. In addition, SFAS 148 amends the disclosure requirements of SFAS 123, “Accounting for Stock-Based Compensation,” to require prominent disclosures in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. The Company adopted the disclosure provisions of SFAS 148 effective April 30, 2003.

In January 2003, the FASB issued Interpretation No. 46, “Consolidation of Variable Interest Entities.” FIN 46 requires an investor with a majority of the variable interests in a variable interest entity to consolidate the entity and also requires majority and significant variable interest investors to provide certain disclosures. A variable interest entity is an entity in which the equity investors do not have a controlling interest or the equity investment at risk is insufficient to finance the entity’s activities without receiving additional subordinated financial support from the other parties. The Company does not expect to identify any variable interest entities that must be consolidated.

4. Commitments and Contingencies

In fiscal 2002, we terminated our operating lease obligations for our Sunnyvale headquarters site by purchasing the land and buildings for $249,840. As a result of headcount reductions in fiscal 2002, we are not currently utilizing certain existing spaces at our California headquarters site. Additionally, we have also exited office spaces under non-cancellable leases in other locations both in the U.S. and Europe. If we are unable to successfully sublease our vacated and unoccupied office space under operating leases, our operating results may be adversely affected. See “Note 12: Restructuring Charges.”

We lease other sales offices and research and development facilities throughout the U.S. and internationally. These sales offices are also leased under operating leases which expire through fiscal 2019. We are responsible for certain maintenance costs, taxes, and insurance under these leases. The aggregate annual minimum rent commitment under our operating leases is included in the minimum annual lease payments schedule below.

Future minimum annual lease payments as of April 30, 2003, are as follows:

Rent expense was $12,609, $18,150, and $18,090 for the years ended April 30, 2003, 2002, and 2001, respectively. Rent expense under certain of our facility leases is recognized on a straight-line basis over the term of the lease. The difference between the amounts paid and the amounts expensed is classified as long-term obligations in the accompanying consolidated balance sheets.

In the past, we entered into agreements and established Network Appliance accounts with Deutsche Banc Alex. Brown whereby we had the option to guarantee any defaults of certain margin loans made to two corporate officers by the financial institution on their Network Appliance stock. In the past, we also entered into an agreement and established a Network Appliance account with Goldman, Sachs and Co. whereby we

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

had the option to guarantee any default of a certain margin loan made to a third corporate officer by the financial institution on his Network Appliance stock. The amount of the guarantee was limited to the excess, if any, of the amount of such loans over the fair market value of the Network Appliance stock securing the loans. As of August 26, 2002, these accounts with Deutsche Banc Alex. Brown and Goldman, Sachs and Co. were closed.

In May 2000, we entered into a split dollar insurance arrangement with our CEO. Under the arrangement, we will pay the annual premiums on several insurance policies on the life of the survivor of our CEO and his wife, and our CEO will reimburse us each year for a portion of those premiums equal to the economic value of the term insurance coverage provided him under the policies. For each of the 2001, 2002 and 2003 fiscal years, we paid an aggregate net annual premium on these split dollar polices in the amount of $2,050. Under the arrangement, we will be reimbursed for all premium payments made on those policies, and it is intended that we will be reimbursed not later than May 2005. Upon the death of both our CEO and his wife or any earlier cash-out of the policies, we will be entitled to a refund of all cumulative premiums paid on these policies by us, and the balance will be paid to our CEO or his designated beneficiaries. The arrangement is terminable by us upon thirty (30)-days prior notice, and such termination will trigger a refund of the net cumulative premiums paid by us on the policies.

From time to time, we have committed to purchase various key components used in the manufacture of our products. Our loss accrual for such commitments to these key component vendors is based on our current forecasts of inventory usage. We establish accruals for estimated losses on purchased components for which we believe it is probable that they will not be utilized in future operations. To the extent that such forecasts are not achieved, our commitments and associated accruals may change.

We are subject to various legal proceedings and claims which may arise in the normal course of business. We do not believe that any current litigation or claims will have a material adverse effect on our business, operating results, or financial condition.

5. Line of Credit

In July 1998, we negotiated a $5,000 unsecured revolving credit facility with a domestic commercial bank. Under terms of the credit facility, which expires in December 2003, we must maintain various financial covenants. Any borrowings under this agreement bear interest at either LIBOR plus 1% or at the lender’s “prime” lending rate, such rate determined at our discretion. As of April 30, 2003, the amounts outstanding under this line of credit amounted to $1,194 relating to workers’ compensation and a foreign lease.

We also have foreign exchange facilities used for hedging arrangements with several banks that allow us to enter into foreign exchange contracts of up to $125,000, of which $7,484 was available at April 30, 2003.

6. Stockholders’ Equity

Preferred Stock — Our Board of Directors has the authority to issue up to 5,000 shares of preferred stock and to determine the price, rights, preferences, privileges, and restrictions, including voting rights, of those shares without any further vote or action by the stockholders.

Stock Option Plans — We adopted the 1993 Stock Option/ Stock Issuance Plan (the “1993 Plan”) in April 1993. In September 1995, we adopted the 1995 Stock Incentive Plan (the “1995 Plan”). The 1995 Plan replaced the 1993 Plan and provides for the grant of options and the issuance of common stock under terms substantially the same as those provided under the 1993 Plan, except that the 1995 Plan does not allow for the exercise of options prior to vesting. Accordingly, all options and shares issued under the 1993 Plan were incorporated into the 1995 Plan upon the effectiveness of our initial public offering.

NETWORK APPLIANCE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Under the 1995 Plan, the Board of Directors may grant to employees, directors and consultants options to purchase shares of our common stock. The exercise price for an incentive stock option and a nonqualified stock option cannot be less than 100% and 85%, respectively, of the fair market value of our common stock as determined by the Board of Directors on the date of grant. Options granted under the 1995 Plan generally vest at a rate of 25% on the first anniversary of the vesting commencement date and then ratably over the following 36 months. Options expire as determined by the Board of Directors, but not more than ten years after the date of grant.

In April 1997, the Board of Directors adopted the Special Non-officer Stock Option Plan (the “Non-officer Plan”) which provides for the grant of options and the issuance of common stock under terms substantially the same as those provided under the 1995 Plan, except that the Non-officer Plan allows only for the issuance of nonqualified options to non-officer employees.

In August 1999, the Board of Directors adopted the 1999 Stock Option Plan (the “1999 Plan”), which is comprised of two separate equity incentive programs: (i) the Discretionary Option Grant Program under which options may be granted to eligible individuals during the service period at a fixed price per share and (ii) the Automatic Option Grant Program under which nonemployee board members will automatically receive special option grants at designated intervals over their period of board service.

The 1999 Plan will supplement the existing 1995 Plan and Non-officer Plan and those plans will continue to remain in full force and effect until all available shares have been issued under each such plan. However, the Automatic Option Grant Program previously in effect under the 1995 Plan terminated as of October 26, 1999, and all automatic option grants made to nonemployee board members on or after that date will be made under the 1999 Plan.

Under the 1999 Plan, the Board of Directors may grant to employees, directors and consultants and other independent advisors options to purchase shares of our common stock during their period of service with us. The exercise price for an incentive stock option and a nonstatutory option cannot be less than 100% of the fair market value of the common stock on the grant date. Options granted under the 1999 Plan generally vest at a rate of 25% on the first anniversary of the vesting commencement date and then ratably over the following 36 months. Options will have a term of ten years after the date of grant, subject to earlier termination upon the occurrence of certain events. In fiscal 2003, the 1999 plan was amended to increase the share reserve by an additional 14,000 shares of common stock and effect certain changes to the Automatic Option Grant Program in effect for the nonemployee members of the Board of Directors.

Options granted under the 1999 Plan are subject to the cancellation/ regrant program with the following limitations: (i) only options held by employees who are neither executive officers nor members of the board can be repriced; and (ii) the total number of repriced options will not exceed 10% of the total number of shares of common stock authorized for issuance under the 1999 Plan.

In fiscal 2001, we assumed various stock option plans in connection with our Orca and WebManage acquisitions. Pursuant to the provisions of the merger agreements, outstanding shares were exchanged under certain exchange ratios in effect at the time of each merger. Options granted under these plans generally vest at a rate of 25% on the first anniversary of the vesting commencement date and then ratably over the following 36 months. Options expire as determined by the Board of Directors, but not more than ten years after the date of grant.

Employee Stock Purchase Plan — Under the Employee Stock Purchase Plan (“ESPP”), employees are entitled to purchase shares of our common stock at 85% of the fair market value at certain specified dates. In fiscal 2003, the plan was amended to increase the share reserve by an additional 2,400 shares of common stock. Of the 13,600 shares authorized to be issued under this plan, 5,156 shares were available for issuance at April 30, 2003, 1,414, 1,094, and 448 shares were issued in fiscal 2003, 2002, and 2001, respectively, at a weighted average price of $10.74, $14.60, and $27.96 respectively.

Deferred Stock Compensation — We recorded $1,171, $1,301, and $14,127 of deferred compensation in fiscal 2003, 2002 and 2001, respectively, primarily related to the recognition of stock compensation of unvested options assumed in the WebManage acquisition, and the grant of stock options to certain highly compensated employees. We reversed $1,612, $5,381 and $34 of deferred compensation in fiscal 2003, 2002, and 2001, respectively, due to employee terminations. The reversals were primarily related to the forfeiture of unvested options assumed in the WebManage acquisition as a result of employee terminations.

Under terms of the 1995 Stock Option Plan, highly compensated employees as defined by our management are eligible to contribute between $15 and $75 in annual salary for the rights to be granted nonqualified stock options. The discount from fair market value, which is equal to the amount of salary contributed, has been recorded as deferred stock compensation expense. The deferred compensation expense is amortized ratably over a one-year period.

Estimated future deferred stock compensation amortization relating to assumed WebManage unvested options and deferred salary investment options for fiscal 2004 are expected to be $1,187. For fiscal 2005, estimated future stock compensation amortization expenses are $176 and none thereafter.

Under terms of the acquisition agreement with Orca, we released shares of common stock to former Orca shareholders upon Orca’s meeting certain performance criteria. The fair market values of these shares were measured on the date the performance criteria were met and were recognized as stock compensation. During fiscal 2003 and 2002, we released an additional 99 and 165 shares of common stock, respectively, valued in the aggregate at $921 and $3,015, respectively. There are no additional performance milestones remaining.

We recorded $748 in compensation expense in fiscal 2003 for the fair value of options granted to a member of the Board of Directors in recognition for services performed outside of the normal capacity of a board member. The 100 common shares under the 1999 Plan were granted at an exercise price of $15.72 per share, the fair market value per share on the grant date. The option has a term of 10 years measured from the grant date, subject to earlier termination following his cessation of board service, and will vest in a series of 48 successive equal monthly installments upon his completion of each month of board service over the 48 month period measured from the grant date.

In fiscal 2003, we reached a final settlement of the escrow fund arrangement under the WebManage acquisition agreement. We have determined the total amount of our losses under the settlement arrangement and 11 restricted shares were released from the escrow and delivered to Network Appliance, valued in the aggregate at $1,210 based on the fair market value of our common stock as of the date of the acquisition. Accordingly, an adjustment was made to the cost of the WebManage acquisition. The balance of the escrow shares has been distributed to former shareholders of WebManage in proportion to their share ownership in WebManage, as provided in the original merger agreement.

In fiscal 2001, under terms of the acquisition agreement with WebManage, we issued an additional 101 shares of common stock to former WebManage stockholders upon WebManage’s meeting certain performance criteria. The fair market value of the shares of $3,000 was measured on the date the performance criteria were met and was recognized as stock compensation.

Current net deferred tax assets are $27,444 and $32,529 as of fiscal 2003 and 2002, respectively. Non-current net deferred tax assets for fiscal 2003 and 2002 are $40,631 and $16,383 respectively, and are included in other assets within the accompanying consolidated balance sheets.

As of fiscal 2003, the federal and state net operating loss carryforwards for income tax purposes were approximately $771,661 and $151,454, respectively. The federal net operating loss carryforwards will begin to expire in fiscal 2011, and the state net operating loss carryforwards will begin to expire in fiscal 2006. As of fiscal 2003, we had federal and state credit carryforwards of approximately $36,380 and $32,112, respectively, available to offset future taxable income. These federal and state credit carryforwards will begin to expire in fiscal 2009.

We have provided a valuation allowance on certain of our deferred tax assets because of uncertainty regarding their realizability due to expectation of future employee stock option exercises. Deferred tax assets of approximately $336,037 and $367,613 at the end of fiscal 2003 and 2002, respectively, pertain to certain tax credits and net operating loss carryforwards resulting from the exercise of employee stock options. If recognized, the tax benefit of these credits and losses will be accounted for as a credit to stockholders’ equity rather than as a reduction of the income tax provision.

operational performance based upon revenue by geographic regions of the segment. Under paragraph 17 of SFAS No. 131, we have one reportable segment as all the geographic operating segments identified can be aggregated into one reportable segment. For the years ended April 30, 2003, 2002 and 2001, we recorded revenue from customers throughout the U.S. and Canada; Europe; Latin America, Australia and Asia Pacific.

The following presents total revenues for the years ended April 30, 2003, 2002, and 2001 by geographic area and long-lived assets as of April 30, 2003 and 2002 by geographic area.

No customer accounted for 10% or more of total revenues in fiscal 2003, 2002, or 2001.


9.	Fair Value of Financial Instruments

The following summary disclosures are made in accordance with the provisions of SFAS No. 107, “Disclosures About Fair Value of Financial Instruments,” which requires the disclosure of fair value information about both on-and off-balance sheet financial instruments where it is practicable to estimate the value. Fair value is defined in SFAS 107 as the amount at which an instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. Because SFAS 107 excludes certain financial instruments and all non-financial instruments from its disclosure requirements, any aggregation of the fair value amounts presented would not represent the underlying value of the Company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

We do not use derivative financial instruments for speculative or trading purposes. We enter into forward foreign exchange contracts to hedge trade and intercompany receivables and payables as well as future sales and operating expenses against future movement in foreign exchange rates.

The forward foreign exchange contracts require us to exchange foreign currencies for U.S. dollars or vice versa and generally mature in less than one year. As of April 30, 2003, we had $117,468 of outstanding foreign exchange contracts in Australian Dollars, British Pounds, Swiss Francs, Canadian Dollars and European Currency Units, that had remaining maturities of five months or less. For the balance sheet hedges, these contracts are adjusted to fair value at the end of each month and are included in other income (expense), net. For the cash flow hedges, the related gains or losses are included in other comprehensive income. As of April 30, 2002, we had $90,459 of outstanding foreign exchange contracts in Australian Dollars, British Pounds, Swiss Francs and European Currency Units, that had remaining maturities of one month or less. These foreign exchange contracts are adjusted to the fair value at the end of every month and are included in other income (expense), net. Gains and losses on these foreign exchange contracts are offset by losses and gains on the underlying assets and liabilities. At April 30, 2003 and 2002, the estimated fair values of forward foreign exchange contracts were $117,516 and $90,603, respectively. Unrealized gains or losses on foreign exchange contracts were not significant at April 30, 2003. The fair value of foreign exchange contracts is based on prevailing financial market information. Other than foreign exchange contracts, we have not entered into any other material financial derivative instruments.

The fair values of cash and cash equivalents, short-term investments and restricted cash reported in the consolidated balance sheets approximate their carrying value. The fair value of short-term investments and foreign exchange contracts is based on quoted market prices. Other investments in equity securities comprise investments in companies in the volatile high-technology market.


10.	Employee Benefit Plan

We have established a 401(k) tax-deferred savings plan (“Savings Plan”). Employees meeting the eligibility requirements, as defined, may contribute specified percentages of their salaries. We contributed $1,315, $1,235 and $1,109 for fiscal 2003, 2002, and 2001, respectively.

11. Acquisitions

In June 2000, we completed the acquisition of Orca, a Waltham, Massachusetts-based developer of high performance Virtual Interface (VI) Architecture software for enterprise-class UNIX and Windows systems. The acquisition fits with our strategy of developing highly available and reliable intelligent storage solutions that improve the performance of today’s Internet and enterprise applications and strengthen our ability to develop next generation storage networking architectures and protocols. The acquisition was accounted for as a purchase. Under terms of the agreement, we acquired Orca for $50,037 in common stock, assumed options and cash, with an obligation to provide 264 shares of common stock, which will result in additional stock compensation charges if certain performance criteria are achieved. Orca met certain performance criteria and as such, we issued and recorded during fiscal 2003 and 2002 an additional 99 and 165 shares of common stock. The fair market value of such shares of $921 and $3,015, respectively, was measured on the date Orca met the performance criteria and was recognized as stock compensation in fiscal 2003 and 2002. There are no additional performance milestones remaining. We also paid certain transaction costs and assumed certain operating assets and liabilities.

The purchase price of the transaction was allocated to the acquired assets and liabilities based on their estimated fair values as of the date of the acquisition. Approximately $26,688 was allocated to in-process research and development and charged to operations because the acquired technology had not reached technological feasibility and had no alternative uses. The value was determined by estimating the costs to develop the acquired in-process technology into commercially viable products, estimating the resulting net

NETWORK APPLIANCE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

cash flows from such projects, and discounting the net cash flows back to their present value. The discount rate included a factor that took into account the uncertainty surrounding the successful development of the acquired in-process technology. These estimates are subject to change, given the uncertainties of the development process, and no assurance can be given that deviations from these estimates will not occur. Costs incurred prior to establishment of technological feasibility are charged to research and development expense and have not been material through April 30, 2003. The Orca acquisition has been successfully utilized for the design and development of the DAFS protocol. By eliminating much of the traditional operating system overhead, DAFS allows for improved I/ O performance while using fewer CPU cycles. The protocol leverages next generation networking technologies that provide remote memory transfer capabilities, including RDMA implemented in VI and Infiniband. The DAFS protocol has good industry support and is now under consideration as an industry standard. We introduced DAFS capable product in April 2002.

In November 2000, we completed the acquisition of WebManage, a Chelmsford, Massachusetts-based software developer of content management, distribution, and analysis solutions. WebManage develops software that intelligently distributes content between various points on the Internet and enables organizations to plan, manage and deliver Internet/intranet services. The acquisition was accounted for as a purchase. Under terms of the agreement, we acquired WebManage for $59,371 in common stock, assumed options, and cash. We also had an obligation to provide shares of common stock to be valued at $3,000 if WebManage achieved certain performance criteria. WebManage met these performance criteria in March 2001 and as such, the contingent consideration was recorded as stock compensation in the fourth quarter of 2001. We also paid certain transaction costs and assumed certain operating assets and liabilities.

In accordance with FASB interpretation No. 44, “Accounting for Certain Transactions involving Stock Compensation,” we recorded the intrinsic value, measured as the difference between the grant price and fair market value on the acquisition consummation date, of unvested options assumed in the WebManage acquisition as deferred stock compensation. Such deferred stock compensation, which aggregated to $12,304, is recorded as a separate component of stockholders’ equity in the accompanying condensed consolidated balance sheet and will be amortized over the vesting term of the related options.

The operating results of Orca and WebManage have been included in the condensed consolidated statements of operations since the respective acquisition dates. The following unaudited pro forma consolidated amounts give effect to these acquisitions as if they had occurred on April 30, 2000 by consolidating the results of operations of the acquired entities with our results for the year ended April 30, 2001.

The pro-forma results of operations give effect to certain adjustments, including amortization of purchased intangibles, goodwill, contingently issuable shares, common stock, and assumed options in connection with the acquisitions. The $26,688 charge for purchased in-process research and development has been excluded from the pro-forma results, as it is a material nonrecurring charge.

12. Restructuring Charges


	*Fiscal 2002 Second Quarter Restructuring Plan*

In August 2001, we implemented a restructuring plan, which included a reduction in workforce by approximately 200 employees and a consolidation of facilities. The action was required to properly align and manage the business commensurate with our then current revenue levels. All functional areas of the Company were affected by the reduction. We completed our actions during the second quarter of fiscal 2002. As a result of this restructuring, we incurred a charge of $7,980. The restructuring charge included $4,796 of severance-related amounts, $2,656 of committed excess facilities and facility closure expenses, and $528 in fixed assets write-offs. The reserve balance of $807 at April 30, 2003 was included in other accrued liabilities.

During fiscal 2002, we purchased our Sunnyvale headquarters site and terminated the operating leases. As a result, an adjustment was made to reduce the previously recorded estimated facilities lease losses by $1,509. During fiscal 2003, we recorded a net restructuring adjustment of $334 due to changes in the estimated costs of certain actions and final resolution of certain restructuring activities. In the event that the foreign facilities are not subleased, we will be obligated for additional total lease payments of approximately $659 to be payable through January 2006.

	*Fiscal 2002 Fourth Quarter Restructuring Plan*

In April 2002, we announced and substantially completed a restructuring related to the closure of an engineering facility and consolidation of resources to the Sunnyvale headquarters, which included a headcount reduction of 34 employees. As a result of this restructuring, we incurred a charge of $5,850. The restructuring charge included $813 of severance-related amounts, $4,564 of committed excess facilities and facility closure expenses, and $473 in fixed assets write-off. Of the reserve balance at April 30, 2003, $1,485 was included in other accrued liabilities and the remaining $3,086 was classified as long-term obligations.

In January 2003, we updated our assumptions and estimates based on certain triggering events, which resulted in an additional net charge of $923, primarily relating to our engineering facility lease. Our estimates are reviewed and revised periodically and may result in a substantial charge to restructuring expense, should different conditions prevail than were anticipated in original management estimates. Such estimates included various assumptions such as the time period over which the facilities will be vacant, expected sublease terms, and expected sublease rates. In the event that the engineering facility is not subleased, we will be obligated for additional total lease payments of $3,385 to be payable through November 2010.

The following analysis sets forth the significant components of the restructuring reserve at April 30, 2003 and 2002:

Of the reserve balances at April 30, 2003 and 2002, $1,485 and $1,061, respectively, were included in other accrued liabilities and the remaining $3,086 and $3,655, respectively, were classified as long-term obligations.

13. Goodwill and Purchased Intangible Assets

We adopted SFAS No. 142 “Goodwill and Other Intangible Assets” effective May 1, 2002. Upon adoption of SFAS No. 142, we discontinued the amortization of our recorded goodwill of $49,422 as of that date, identified our reporting units based on our current segment reporting structure and allocated all recorded goodwill, as well as other assets and liabilities, to the reporting units. We concluded that our reporting units are the same as our operating segments. Under SFAS No. 142, goodwill attributable to each of our reporting units is required to be tested for impairment by comparing the fair value of each reporting unit with its carrying value. As of May 1, 2002, this evaluation indicated that the fair value for each of our reporting units exceeded the reporting unit’s carrying amount and no impairment was recognized. On an ongoing basis, goodwill is reviewed annually for impairment (or more frequently if indicators of impairment arise). As of April 30, 2003, there had been no impairment of goodwill and intangible assets. There can be no assurance that future impairment tests will not result in a charge to earnings.

In connection with the adoption of SFAS No. 142, we also reassessed the useful lives and the classification of our purchased intangible assets and determined that they continued to be appropriate except for acquired workforce net of deferred tax liabilities of $502, which was reclassified into goodwill.

A reconciliation of our previously reported net income and net income per share to amounts for the exclusion of goodwill amortization net of the related income tax effect follows:

Existing technology is amortized over three years and total amortization expense for existing technology was $5,478, $5,726 and $2,625 in fiscal 2003, 2002 and 2001, respectively and such amounts were included in cost of product revenue. For fiscal 2004, estimated future amortization expense is $2,954 and none thereafter.

14. Guarantees

As of April 30, 2003, our financial guarantees consisted of standby letters of credit outstanding, bank guarantee, and restricted cash, which were related to facility lease requirements, product performance guarantees, customs and duties guarantees, VAT requirements, and workers’ compensation plans. The maximum amount of potential future payments under these arrangements was $2,630 as of April 30, 2003. Of this maximum exposure, $1,142 of restricted cash was classified under Other Assets on our balance sheet at April 30, 2003. We have not recorded any liability at April 30, 2003 related to these guarantees.

We provide both recourse and non-recourse lease financing options to our customers. Under the terms of recourse leases, which are generally 3 years or less, we remain liable for the aggregate unpaid remaining lease payments. We defer 100% of the recourse lease obligation and recognize revenue over the term of the lease as the lease payments become due. As of April 30, 2003 the maximum recourse exposure totaled approximately $4,940. Under the terms of the non-recourse leases, we do not have any continuing obligations or liabilities. To date, we have not experienced significant losses under this lease financing program.

We do not maintain a general warranty reserve for estimated costs of product warranties at the time revenue is recognized due to our extensive product quality program and processes and because our customer service inventories utilized to correct product failures are carried at zero cost.

We defend and indemnify our customers for damages and reasonable costs incurred in any suit or claim brought against them alleging that our products sold to our customers infringe any U.S. patent, copyright, trade secret or similar right. If a product becomes the subject of an infringement claim, we may, at our option: (i) replace the product with another non-infringing product that provides substantially similar performance; (ii) modify the infringing product so that it no longer infringes but remains functionally equivalent; (iii) obtain the right for the customer to continue using the product at our expense and for the reseller to continue selling the product; (iv) take back the infringing product and refund to customer the purchase price paid less depreciation amortized on a straight line basis. We have not been required to make material payments pursuant to these provisions historically. We have not identified any losses that are probable under these provisions and, accordingly, we have not recorded a liability related to these indemnification provisions.

15. Subsequent Events

On May 13, 2003, we announced that the Board of Directors has approved a $150,000 stock repurchase program to purchase shares of our outstanding common stock. The duration of the repurchase program is open-ended. Under the program, Network Appliance, Inc. could purchase shares of common stock through open market transactions at prices deemed appropriate by management. The timing and amount of repurchase transactions under this program will depend on market conditions and corporate and regulatory considerations. The purchases will be funded from available working capital. The stock repurchase program may be suspended or discontinued at any time.

Item 14.	*Controls and Procedures*

Disclosure Controls are procedures designed to ensure that information required to be disclosed in our reports filed under the Exchange Act, such as this Annual Report, is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms. Disclosure Controls are also designed to ensure that such information is accumulated and communicated to our management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

Based on their evaluation, as of a date within 90 days of the filing of this Annual Report on Form 10-K, the Company’s Chief Executive Officer and Chief Financial Officer have concluded the Company’s disclosure controls and procedures (as defined in Rule 13a-14 and 15d-14 under the Securities Exchange Act of 1934) are effective. There have been no significant changes in internal controls or in other factors that could significantly affect those controls subsequent to the date of their evaluation, including any corrective actions with regard to significant deficiencies and material weaknesses. However, in May 2003, we implemented new enterprise-wide software, as well as new business processes and procedures to support the software. These changes are the result of our normal business process to evaluate and upgrade or replace our systems software and related business processes to support our evolving operational needs. The new software and processes will be used to record and report our financial results for fiscal 2004.
