Therefore, actual outcomes and results may differ materially from what is expressed or forecast in such forward-looking statements. Words such as "expect," "anticipate," "intend," "plan," "believe," "seek," "estimate," variations of such words and similar expressions are intended to identify such forward looking statements. General Linear Technology Corporation (together with its consolidated subsidiaries, "Linear Technology" or the "Company") designs, manufactures and markets a broad line of standard high performance linear integrated circuits. Applications for the Company's products include telecommunications, cellular telephones, networking products such as optical switches, notebook and desktop computers, computer peripherals, video/multimedia, industrial instrumentation, security monitoring devices, high-end consumer products such as digital cameras and MP3 players, complex medical devices, automotive electronics, factory automation, process control, and military and space systems. The Company was organized and incorporated in 1981 by a management team with significant experience in the design, manufacture and marketing of linear circuits. During fiscal year 2001, the Company reincorporated from California to Delaware. The Company competes primarily on the basis of performance, functional value, quality, reliability and service. The linear circuit industry Semiconductor components are the electronic building blocks used in electronic systems and equipment. These components are classified as either discrete devices (such as individual transistors) or integrated circuits (in which a number of transistors and other elements are combined to form a more complicated electronic circuit). Integrated circuits ("ICs") may be divided into two general categories, digital and linear (or analog). Digital circuits, such as memory devices and microprocessors, generally process on-off electrical signals, represented by binary digits, "1" and "0." In contrast, linear circuits monitor, condition, amplify or transform continuous analog signals associated with physical properties, such as temperature, pressure, weight, light, sound or speed, and play an important role in bridging between real world phenomena and a variety of electronic systems. Linear circuits also provide voltage regulation and power control to electronic systems, especially in hand-held battery powered systems. The Company believes that several factors generally distinguish the linear integrated circuit business from the digital circuit business, including: Importance of Individual Design Contribution. The Company believes that the creativity of individual design engineers is of particular importance in the linear circuit industry. The design of a linear integrated circuit generally involves a greater variety and less repetition of circuit elements than digital design. In addition, the interaction of linear circuit elements is complex, and the exact placement of these elements in the circuit is critical to the circuit's precision and performance. Computer-aided engineering and design tools for linear circuits are not as accurate in modeling circuits as those tools used for designing digital circuits. As a result, the contributions of a relatively small number of individual design engineers are generally of greater importance in the design of linear circuits than in the design of digital circuits. Smaller Capital Requirements. Digital circuit design attempts to minimize device size and maximize speed by increasing circuit densities. The process technology necessary for increased density requires very expensive wafer fabrication equipment. In contrast, linear circuit design focuses on precise matching and placement of circuit elements, and linear circuits often require large feature sizes to achieve precision and high voltage operation. Accordingly, the linear circuit manufacturing process generally requires smaller initial capital expenditures, particularly for photomasking equipment and clean room facilities, and less frequent replacement of manufacturing equipment because the equipment has, to date, been less vulnerable to technological obsolescence. Market Diversity; Relative Pricing Stability. Because of the varied applications for linear circuits, manufacturers typically offer a greater variety of device types to a more diverse group of customers, who typically 1 have smaller volume requirements per device. As a result, linear circuit manufacturers are often less dependent upon particular products or customers, linear circuit markets are generally more fragmented, and competition within those markets tends to be more diffused. The Company believes that competition in the linear circuit market is particularly dependent upon performance, functional value, quality, reliability and service. As a result, linear circuit pricing has generally been more stable than most digital circuit pricing. Less Japanese And Other Asian Competition. To date, Japanese and other Asian firms have concentrated their efforts on the high volume digital and consumer linear markets, as opposed to the high performance end of the linear circuit market served by the Company. Products and markets Linear Technology produces a wide range of products for a variety of customers and markets. The Company emphasizes standard products to address larger markets and to reduce the risk of dependency upon a single customer's requirements. The Company targets the high performance segment of the linear circuit market. "High performance" is characterized by higher precision, both high power or micropower, higher speed, more subsystem integration on a single chip and many other special features. The Company focuses virtually all of its design efforts on proprietary products which, at the time of introduction, are original designs by the Company offering unique characteristics differentiating them from those offered by competitors. Although the types and mix of linear products vary by application, the principal product categories are as follows: Amplifiers - These circuits amplify the voltage or output current of a device. The amplification represents the ratio of the output voltage or current to the input voltage or current. The most widely used device is the operational amplifier due to its versatility and precision. High Speed Amplifiers - These amplifiers are used to amplify signals above 5MHz for applications such as video, fast data acquisition and data communication. Voltage Regulators - Voltage regulators control the voltage of a device or circuit at a specified level. This category of product consists primarily of two types, the linear regulator and the switch mode regulator. Switch mode regulators are also used to convert voltage up or down within an electronic system for power management and battery charging. Voltage References - These circuits serve as electronic benchmarks providing a constant voltage for system usage. Precision references have a constant output independent of input, temperature changes or time. Interface - Interface circuits act as an intermediary to transfer digital signals between or within electronic systems. These circuits are used in computers, modems, instruments and remote data acquisition systems. Data Converters - These circuits change linear (analog) signals into digital signals, or vice versa, and are often referred to as data acquisition subsystems, A/D converters and D/A converters. The accuracy and speed with which the analog signal is converted to its digital counterpart is considered a key characteristic for these devices. Radio Frequency Circuits - These circuits include mixers, modulators, demodulators, amplifiers, drivers, and power detectors and controllers. They are used in wireless and cable infrastructure, cellphones, and wireless data communications. Other - Other linear circuits include buffers, battery monitors, motor controllers, hot swap circuits, comparators, sample-and-hold devices, modulators/demodulators, drivers and filters, both switched capacitor and continuous time, which are used to limit and/or manipulate signals in such applications as cellular telephones, base stations, navigation system instrumentation and detection circuitry. Linear circuits are used in various applications including telecommunications, cellular telephones, networking products such as optical switches, notebook and desktop computers, computer peripherals, video/multimedia, industrial instrumentation, security monitoring devices, high-end consumer products such as digital cameras and MP3 players, complex medical devices, automotive electronics, factory automation, process control, and military and space systems. The Company focuses its product development and marketing efforts on high performance applications where the Company believes it can position itself competitively with respect to product performance and functional value. 2 The following table sets forth, examples of product families by end market application and end-market: Market End Applications/Products Example Product Families -- Industrial Flow or rate metering | Position/pressure/ | temperature sensing and control | Robotics | Energy management | Process control data communication | Network and factory automation | Security and surveillance systems | Curve tracers | Data acquisition products Logic analyzers | High performance operational Multimeters | amplifiers Oscilloscopes | Interface (RS 485/232) products Test equipment | Instrumentation amplifiers Voltmeters | Line drivers Network analyzers | Line receivers Scales | Precision comparators Analytic instruments | Precision voltage references Gas chromatic graphs | Monolithic filters EKG, CAT scanners | Switching voltage regulators DNA analysis | Voltage references Blood analyzers | Hot swap circuits | DC-DC converters Space/Military Communications | and Automotive Satellite | Guidance and navigation systems | Displays | Firing control | Ground support equipment | Radar systems | Sonar systems | Surveillance equipment | GPS | Entertainment | Safety systems | Suspension systems __| -- Communications Cellular phones (CDMA/WCDMA/GPRS/3G) | DC - DC converters Cellular basestations | V.35 transceiver Pagers | High-speed amplifiers Modems/fax machines | Line drivers PBX switches | Line receivers GPS systems | Low noise operational amplifiers Optical networking | Micropower products ADSL modems | Power management Channel service unit/data service unit | Switched capacitor filters Cable modems | Voltage references Internet appliances | Voltage regulators Servers | Data acquisition products Routers | Hot Swap controllers Switches | Multi-protocol circuits | Thermal Electric Cooler | Power Amplifier Control | Modulators/Demodulators | Battery Chargers __| Multi-Phase Switching Regulators 3 -- Computer Communications/interface modems | Battery charging Disk drives | DC - DC converters Notebook computers | Data acquisition products Desktop computers | Hot Swap controllers Workstations | Line drivers LCD displays/monitors | Line receivers Plotters/printers | Low drop out linear regulators Digital still cameras | Micropower products Power supplies | Multi-Phase Switching Regulators Handheld PCs | PCMCIA power switching Battery chargers | Power management Video/multimedia | MP3 players | PDAs | Pet Robots __| Marketing and customers The Company markets its products worldwide, through a direct sales staff, electronics distributors, and a small network of independent sales representatives, to a broad range of customers in diverse industries. Within the United States, in late fiscal 2001, the Company transitioned its sales effort from a network of independent sales representatives primarily to a direct sales staff. Additionally in fiscal 2001 the Company reduced its number of large national distributors from two to one. The Company sells to over 15,000 Original Equipment Manufacturer (OEM) customers directly and/or through the sales distributor channel. Distributor and direct customers generally buy on an individual purchase order basis, rather than pursuant to long-term agreements. Of the Company's domestic distributors, one domestic distributor accounted for 16% of net sales and 17% of accounts receivable during fiscal 2002, and 12% of net sales and 13% of accounts receivable during fiscal 2001, two distributors accounted for approximately 14% and 11% of net sales in fiscal 2000. Distributors are not end customers, but rather serve as a channel of sale to many end users of the Company's products. No other distributor or customer accounted for 10% or more of net sales for fiscal 2002, 2001 or 2000. The Company's sales organization is divided into domestic and international regions, with sales offices located in the following metropolitan areas: Seattle, Baltimore, Denver, Philadelphia, Raleigh, Chicago, Dallas, Austin, Houston, San Jose, Los Angeles, Irvine, San Diego, Huntsville, Minneapolis, Cleveland, Portland, London, Stockholm, Helsinki, Ascheberg, Munich, Stuttgart, Paris, Lyon, Tokyo, Osaka, Taipei, Singapore, Seoul, Hong Kong, Bejing and Shanghai. The Company's products typically require a sophisticated technical sales effort. The Company has agreements with 4 independent sales representatives in the United States and 2 in Canada. Commissions are paid to sales representatives upon shipments either directly from the Company or through distributors. The Company has agreements with 2 independent distributors in North America, 5 in Europe, 2 in Japan, 2 each in China and Taiwan, and 1 each in Korea, Singapore, Malaysia, Thailand, South Africa, Philippines, India, Israel, Australia, and New Zealand. The Company's distributors purchase the Company's products for resale to customers. Additionally, domestic distributors often sell competitors' products. Under certain agreements, the Company's domestic distributors are entitled to price protection on inventory if the Company lowers the prices of its products. The agreements also generally permit distributors to exchange up to 3% of purchases on a semi-annual basis. See Note 1 of Notes to Consolidated Financial Statements incorporated herein by reference to Exhibit 13.1 of this Form 10-K, which contains certain information included in the Company's 2002 Annual Report to Stockholders. During fiscal 2002, 2001 and 2000, export sales were primarily to Europe, Japan and Asia and represented approximately 64%, 54% and 54% of net sales, respectively. Because most of the Company's export sales are billed and payable in United States dollars, export sales are generally not directly subject to fluctuating currency exchange rates. A strengthening of the dollar in relation to other currencies may, however, create pricing pressure. Although export sales are subject to certain control restrictions, including approval by the Office of Export Administration of the United States Department of Commerce, the Company has not experienced any material difficulties relating to such restrictions. 4 The Company's backlog of released and firm orders was approximately $46.1 million at June 30, 2002 as compared with $71.5 million at July 1, 2001. In addition to its backlog, the Company had $28.8 million of products sold to and held by domestic distributors at June 30, 2002 as compared to $31.8 million at July 1, 2001. Generally, shipments to domestic distributors are not recognized as sales until the distributor has sold the products to its customers. The Company defines backlog as consisting of distributor stocking orders and OEM orders for which a delivery schedule has been specified by the OEM customer for product shipment within six months. Although the Company receives volume purchase orders, most of these purchase orders are cancelable, generally outside of thirty days of delivery, by the customer without significant penalty. Lead-time for the release of purchase orders depends upon the scheduling practices of the individual customer and the availability of individual products, so the rate of booking new orders varies from month to month. The ordering practices of many semiconductor customers has shifted from a practice of placing orders with delivery dates extending over several months to the practice of placing orders with shorter delivery dates in concert with the Company's lead times. Also, the Company's agreements with certain distributors provide for price protection. Consequently, the Company does not believe that its backlog at any time is necessarily representative of actual sales for any succeeding period. In the operating history of the Company, seasonality of business has not been a material factor, although the results of operations for the first fiscal quarter of each year are impacted slightly by customary summer holidays, particularly in Europe. The Company warrants that its products, until they are incorporated in other products, are free from defects in workmanship and materials and conform to the Company's published specifications. Warranty expense has been nominal to date. Manufacturing The Company's wafer fabrication and manufacturing facilities are located in Milpitas, California ("Hillview") and Camas, Washington ("Camas"). Each facility was built to Company specifications to support a number of sophisticated process technologies and to satisfy rigorous quality assurance and reliability requirements of United States military specifications and major worldwide OEM customers. All of the Company's manufacturing facilities have received ISO 9001/ISO 9002 certification. The Company's wafer fabrication facility located in Camas, Washington commenced manufacturing operations in the second half of fiscal 1997, the facility is used to produce six-inch diameter wafers for use in the production of the Company's devices. In fiscal 1999, the Company added 40,000 square feet to the Camas facility and during fiscal 2001 the Company purchased an additional 16.5 acres adjacent to its Camas facility for future expansion. The Company's Hillview facility located in Milpitas, California was completed in fiscal 2001. Production for this six-inch wafer fabrication plant commenced in the third quarter of fiscal 2001. The Company currently uses similar manufacturing processes in both its Hillview and Camas facilities. During fiscal 2002, the Company discontinued production in its oldest 4-inch wafer fabrication plant located at the Milpitas, California headquarters. The Company's basic process technologies include high speed bipolar, high gain, low noise bipolar, radio frequency bipolar, silicon gate complementary metal-oxide semiconductor ("CMOS") and BiCMOS processes. The Company also has two proprietary complementary bipolar processes. The Company's bipolar processes are typically used in linear circuits where high voltages, high power, high frequency, low noise or effective component matching is necessary. The Company's proprietary silicon gate CMOS processes provide switch characteristics required for many linear circuit functions, as well as an efficient mechanism for combining linear and digital circuits on the same chip. The Company's CMOS processes were developed to address the specific requirements of linear circuit functions. The complementary bipolar processes were developed to address higher speed analog functions. The Company's basic processes can be combined with a number of adjunct processes to create a diversity of IC components. A minor portion of the Company's wafer manufacturing, particularly very small features size CMOS products, is done at an independent foundry. The accompanying chart provides a brief overview of the Company's IC process capabilities: 5 PROCESS CAPABILITIES Process Families Benefit/Market Advantage Product Application - ---------------- ------------------------ ------------------- P-Well SiGate CMOS General purpose, stability Switches, filters, data conversion, chopper amplifiers N-Well SiGate CMOS Speed, density, stability Switches, data conversion BiCMOS Speed, density, stability, flexibility Data conversion High Power Bipolar Power (100 watts), high current Linear and smart power products, (10 amps) switching regulators Low Noise Bipolar Precision, low current, low noise, Op amps, voltage references high gain High Speed Bipolar Fast, wideband, video high data Op amps, video, comparators, rate switching regulators JFETS Speed, precision, low current Op amps, switches, sample and hold Rad - Hard Total dose radiation hardened All space products Complementary Bipolar Speed, low distortion, precision Op amps, video amps, converters CMOS/ Thin Films Stability, precision Filters, data conversion High Voltage CMOS High voltage general-purpose, Switches, chopper amplifiers compatible with Bipolar Bipolar/Thin Films Precision, stability, matching Converters, amplifiers RF Bipolar High speed, low power RF wireless, high speed data communications The Company emphasizes quality and reliability from initial product design through manufacturing, packaging and testing. The Company's design team focuses on fault tolerant design and optimum location of circuit elements to enhance reliability. Linear Technology's wafer fabrication facilities have been designed to minimize wafer handling and the impact of operator error through the use of microprocessor-controlled equipment. The Company has obtained Defense Supply Center, Columbus (DSCC) qualification to participate in high reliability JAN38510 (class B) military business. The Company has also received Jan Class S Microcircuit Certification, which enables the Company to manufacture products intended for use in space or for critical applications where replacement is extremely difficult or impossible and where reliability is imperative. The Company is certified to comply with the ISO 9001/9002 international quality standard and QS 9000 automotive quality standard. This certification covers the Company's design, manufacturing and service organizations and is an important standard especially in the European marketplace. The Company has received MIL-PRF-38535 Qualified Manufacturers Listing (QML) certification for military products from DSCC. Processed wafers are sent to either the Company's assembly facility in Penang, Malaysia or to offshore independent assembly contractors where the wafers are separated into individual circuits and packaged. The Penang facility opened in October 1994 and services approximately 60% to 90% of the Company's assembly requirements for plastic packages. The Company completed an extension of approximately 75,000 square feet to the Penang facility in late fiscal 2000. Significant assembly subcontractors used by the Company are Carsem(M) Sdn, Carsem Semiconductor Sdn and Unisem(M) Sdn located in 6 Malaysia. The Company also maintains domestic assembly operations to satisfy particular customer requirements, especially those for military applications, and to provide rapid turnaround for new product development. After assembly, most products are sent to the Company's Singapore facility for final testing, inspection and packaging as required. Some products are returned to Milpitas for the same back-end processing. Linear Technology from time to time has experienced competition from other manufacturers seeking assembly of circuits by independent contractors. The Company currently believes that alternative foreign assembly sources could be obtained without significant interruption. Foreign assembly is subject to risks normally associated with foreign operations, including changes in local governmental policies, currency fluctuations, transportation delays and the imposition of export controls or increased import tariffs. From time to time certain materials, including silicon wafers and plastic molding compounds, have been in short supply. To date the Company has experienced no delays in obtaining raw materials which could have adversely affected production. As is typical in the industry, the Company must allow for significant lead times in delivery of its materials. Manufacturing of individual products, from wafer fabrication through final testing, may take from ten to sixteen weeks. Since the Company sells a wide variety of device types, and customers typically expect delivery of products within a short period of time following order, the Company maintains a substantial work-in-process and finished goods inventory. Based on its anticipated production requirements, the Company believes it will have sufficient available resources and manufacturing capacity for fiscal 2003. Patents, licenses and trademarks The Company has been awarded over 166 United States and International patents, and has filed 103 additional patent applications. Although the Company believes that these patents and patent applications may have value, the Company's future success will depend primarily upon the technical abilities and creative skills of its personnel, rather than on its patents. As is common in the semiconductor industry, the Company has at times been notified of claims that it may be infringing patents issued to others. If it appears necessary or desirable, the Company may seek licenses under such patents, although there can be no assurance that all necessary licenses can be obtained by the Company on acceptable terms. In addition, from time to time the Company may negotiate with other companies to license patents, products or process technology for use in its business. Government sales The Company currently has no material U.S. Government contracts. Risks and Competition In addition to the risks discussed below and elsewhere in this "Business section", see the "Factors Affecting Future Operating Results" section included in Exhibit 13.1-3, "Management's Discussion and Analysis," for further discussion of other risks and uncertainties that may affect the business. Semiconductor Industry The semiconductor market has historically been cyclical and subject to significant economic downturns at various times, including the recent decline in demand experienced during fiscal 2002. Many OEM customers have significant excess inventories in their channels thus making it difficult for the Company to know real end user demand. The cyclical nature of the semiconductor industry may cause the Company to experience substantial period-to-period fluctuations in results of operations. Typically, the Company's ability to meet its revenue goals and projections is dependent to a large extent on the orders it receives from its customers within the period. Historically, the Company has maintained low lead times, which have enabled customers to place orders close to their true needs for product. In defining its goals and projections the Company considers inventory on hand, backlog, production cycles and expected order patterns from customers. If the Company's estimates in these areas become inaccurate, it may not be able to meet its revenue goals and projections. In addition, some customers 7 require the Company to manufacture product and have it available for shipment, even though the customer is unwilling to make a binding commitment to purchase all, or even some, of the product. The semiconductor industry is characterized by rapid technological change, price erosion, occasional shortages of materials, capacity constraints, variations in manufacturing efficiencies, and significant expenditures for capital equipment and product development. New product introductions are a critical factor for future sales growth and sustained profitability. Although the Company believes that the high performance segment of the linear circuit market is generally less affected by price erosion or by significant expenditures for capital equipment and product development than other semiconductor market sectors, future operating results may reflect substantial period to period fluctuations due to these or other factors. Manufacturing The Company relies on its internal manufacturing facilities located in California and Washington to fabricate most of its wafers; however, the Company is dependent on outside silicon foundries for a small portion of its wafer fabrication. The Company could be adversely affected in the event of a major earthquake, which could cause temporary loss of capacity, loss of raw materials, and damage to manufacturing equipment. Additionally the Company relies on its internal and external assembly and testing facilities located in Singapore and Malaysia. The Company is subject to economic and political risks inherent to international operations, including changes in local governmental policies, currency fluctuations, transportation delays and the imposition of export controls or increased import tariffs. The Company could be adversely affected if any such changes are applicable to the Company's foreign operations. The Company's manufacturing yields are a function of product design and process technology, both of which are developed by the Company. The manufacture and design of integrated circuits is highly complex. To the extent the Company does not achieve acceptable manufacturing yields or there are delays in wafer fabrication, its results of operations could be adversely affected. Litigation The Company is subject to various legal proceedings arising out of a wide range of matters, including, among others, patent suits and employment claims. From time to time, as is typical in the semiconductor industry, the Company receives notice from third parties alleging that the Company's products or processes infringe such third parties' intellectual property rights. If the Company is unable to obtain a necessary license, and one or more of its products or processes is determined to infringe any such intellectual property rights of others, a court might enjoin the Company from further manufacture and/or sale of the affected products. In that case, the Company would need to reengineer the affected products or processes in such a way as to avoid the alleged infringement, which may or may not be possible. An adverse result in litigation arising from such a claim could involve an injunction to prevent the sales of a portion of the Company's products, a reduction or the elimination of the value of related inventories, and/or the assessment of a substantial monetary award for damages related to past sales. The Company does not believe that the current suits will have a material impact on its business or financial condition. However, current lawsuits and any future lawsuits will divert resources and could result in the payment of substantial damages. See "Item 3. Legal Proceedings." Key Personnel The Company's performance is substantially dependent on the performance of the executive officers and key employees. The loss of the services of the key officers, technical personnel or other key employees could harm the business. The success of the Company depends on its ability to identify, hire, train, develop and retain highly qualified technical and managerial personnel. Failure to attract and retain the necessary technical and managerial personnel could harm the Company. Competition Linear Technology competes in the high performance segment of the linear market. The Company's competitors include Analog Devices, Inc., Maxim Integrated Products, Inc., Motorola, Inc., Micrel Inc., National Semiconductor Corporation and Texas Instruments, Inc. Competition among manufacturers of linear integrated circuits is intense, and certain of the Company's competitors may have significantly greater financial, technical, manufacturing and marketing resources than the Company. The principal elements of competition include product performance, functional value, quality and reliability, technical service and support, price, diversity of product line and delivery capabilities. The Company believes it competes 8 favorably with respect to these factors, although it may be at a disadvantage in comparison to larger companies with broader product lines and greater technical service and support capabilities. Although the Company believes that it has the product lines, manufacturing facilities and technical and financial resources for its current operations, sales and profitability can be significantly affected by the above and other factors. Additionally, the Company's common stock could be subject to significant price volatility should sales and/or earnings fail to meet the expectations of the investment community. Furthermore, stocks of high technology companies are subject to extreme price and volume fluctuations that are often unrelated or disproportionate to the operating performance of these companies. Research and development The Company's ability to compete depends in part upon its continued introduction of technologically innovative products on a timely basis. To facilitate this need, the Company has organized its product development efforts into four groups: power management, signal conditioning, mixed signal and high frequency. Linear Technology's product development strategy emphasizes a broad line of standard products to address a diversity of customer applications. The Company's research and development efforts are directed primarily at designing and introducing new products and, to a lesser extent, developing new processes and advanced packaging. As of June 30, 2002, the Company had 681 employees involved in research, development and engineering related functions of which 336 employees are engaged in new product design. The Company had 214 employees engaged in new product design at its Milpitas headquarters as well as 14 employees at its Singapore design center, 46 employees at its Boston design center, 24 employees at its Colorado design center, 12 employees at its New Hampshire design center, 11 employees at its Raleigh design center which opened in fiscal 2000, 7 employees at its Santa Barbara design center which opened in fiscal 2001, and 8 at its Burlington design center which opened in fiscal 2002. For the fiscal years 2002, 2001, and 2000, the Company spent approximately $79.8 million, $102.5 million, and $78.3 million, respectively, on research and development. The reduction in expenses in 2002 from 2001 was due primarily to a reduction in profit sharing expense. Headcount in total R&D personnel increased from 670 in fiscal 2001 to 681 in fiscal 2002. Within R&D the number of actual circuit designers increased from 139 to 161 in fiscal 2002. Environmental regulation Federal, state and local regulations impose various environmental controls on the storage, use, discharge and disposal of certain chemicals and gases used in semiconductor processing. The Company's facilities have been designed to comply with these regulations, and the Company believes that its activities conform to present environmental regulations. Increasing public attention has, however, been focused on the environmental impact of electronics manufacturing operations. While the Company to date has not experienced any materially adverse business effects from environmental regulations, there can be no assurance that changes in such regulations will not require the Company to acquire costly remediation equipment or to incur substantial expenses to comply with such regulations. Any failure by semiconductor companies, including the Company, to control the storage, use or disposal of, or adequately restrict the discharge of hazardous substances could also subject them to significant liabilities. Employees As of June 30, 2002, the Company had 2,691 employees, including 256 in marketing and sales, 681 in research, development and engineering related functions, 1,664 in manufacturing and production, and 90 in management, administration and finance. The Company's success depends upon a number of key employees, the loss of whom could adversely impact the Company. The Company believes that its future success will depend in large part upon its ability to attract, retain and motivate highly skilled employees. In the San Jose/Silicon Valley area, where the Company's principal facilities are located, competition for such employees is intense. The Company has never had a work stoppage, no employees are represented by a labor organization, and the Company considers its employee relations to be good. 9 Executive Officers of the Registrant The executive officers of the Company, and their ages as of September 9, 2002, are as follows: Name Age Position - ---- --- -------- Robert H.

Item 3. Legal Proceedings To protect its intellectual property, and in particular its patent rights, the Company has been the plaintiff in various patent infringement lawsuits. The defendants' responses to litigation initiated by the Company have in certain cases included counterclaims or separate actions alleging infringement by the Company of unrelated patents owned by the defendant. One such instance has arisen in which Texas Instruments, Inc. (TI) filed suit against the Company on January 6, 2001, in federal court in Texas. This suit alleges that certain semiconductor manufacturing equipment, purchased by the Company from independent third party suppliers and used by the Company in its manufacturing processes, infringed three patents owned by TI. The suit seeks unspecified monetary damages and injunctive relief. In the course of defending the lawsuit brought by TI, the Company has filed third-party complaints against the manufacturers of the allegedly infringing equipment, seeking indemnity and alleging breach of contract, breach of warranty, fraud, and unfair business practices. While the Company believes that resolution of these actions should not have a material effect on the Company's financial position, it can give no assurances that it will prevail in them. Item 4.
