      This business strategy enables us to win large outsourcing programs from leading multinational OEMs. Our customers consist of OEMs that operate in a range of industries, and include Alcatel, Cisco, Dell, EchoStar, Ericsson, HP, IBM, McData, Nokia, Nortel and Roche. Our net sales, operating income, long-lived assets, depreciation and amortization, and capital expenditures attributable to geographic segments are presented in Note 11 to our consolidated financial statements included in Item 15 of this report.

Industry Overview

      EMS companies are the principal beneficiaries of the increased use of outsourced manufacturing services by the electronics and other industries. Outsourced manufacturing refers to OEMs’ use of EMS companies, rather than internal manufacturing capabilities, to manufacture their products. Historically, EMS companies generally manufactured only components or partial assemblies. As the EMS industry has evolved, OEMs have increased their reliance on EMS companies for additional, more complex manufacturing services, including design services. Some EMS companies now often manufacture and test complete systems and manage the entire supply chains of their customers. Industry leading EMS companies offer end-to-end services, including product design and engineering, volume manufacturing, final system assembly and test, direct order fulfillment, after-market product service and support and global supply chain management.

      Increased outsourced manufacturing by OEMs is expected to continue because it allows OEMs to:

      Reduce Operating Costs and Capital Investment. In the current economic environment, OEMs are under significant pressure to reduce manufacturing costs and capital expenditures. EMS companies can provide OEMs with flexible, cost-efficient manufacturing services. In addition, as OEM products have become more technologically advanced, the manufacturing and system test processes have become increasingly automated and complex, requiring significant capital investments. EMS companies enable OEMs to access technologically advanced manufacturing and test equipment and facilities, without additional capital expenditures.

      Focus on Core Competencies. The electronics industry is highly competitive and subject to rapid technological change. As a result, OEMs increasingly are focusing their resources on activities and technologies in which they expect to add the greatest value. By offering comprehensive manufacturing services and supply chain management, EMS companies enable OEMs to focus on their core competencies, including next generation product design and development as well as marketing and sales.

      Access Leading Design and Engineering Capabilities. The design and engineering of electronics products has become more complex and sophisticated and in an effort to become more competitive, OEMs are increasingly relying on EMS companies to provide product design and engineering support services. EMS companies’ design and engineering services can provide OEMs with improvements in the performance, cost and time required to bring products to market. EMS companies are providing more sophisticated design and engineering services to OEMs, including the design and engineering of complete products following an OEM’s development of a product concept.

      Improve Supply Chain Management and Purchasing Power. OEMs face challenges in planning, procuring and managing their inventories efficiently due to fluctuations in customer demand, product design changes, short product life cycles and component price fluctuations. EMS companies employ sophisticated production management systems to manage their procurement and manufacturing processes in an efficient and cost-effective manner so that, where possible, components arrive on a just-in-time, as-and-when needed basis. EMS companies are significant purchasers of electronic components and other raw materials, and can capitalize on the economies of scale associated with their relationships with suppliers to negotiate price discounts, obtain components and other raw materials that are in short supply, and return excess components. EMS companies’ expertise in supply chain management and their relationships with suppliers across the supply chain enable them to help OEMs reduce their cost of goods sold and inventory exposure.

      Access Global Manufacturing Services. OEMs seek to reduce their manufacturing costs by having EMS companies manufacture their products in the lowest cost locations that are appropriate for their products and end customers. OEMs also are increasingly requiring particular products to be manufactured simultaneously

Our Business Strategy

      Our objective is to maintain and enhance our leadership position in the EMS industry. Key elements of our strategy include:

      Capitalizing on Our Comprehensive Services. We intend to capitalize on our end-to-end services, which we believe will allow us to both sell additional services to our existing customers and attract new customers. Our end-to-end services include product design and engineering, volume manufacturing, final system assembly and test, direct order fulfillment, after-market product service and support and supply chain management. Our vertically integrated volume manufacturing services enable us to manufacture additional system components and subassemblies for our customers. When we provide a customer with a number of services, such as component manufacturing or higher value-added services, we often are able to improve our margins and profitability. Consequently, our goal is to increase the number of manufacturing programs for which we provide multiple services. To achieve this goal, our sales and marketing organization seeks to cross-sell our services to customers.

      Extending Our Technology Leadership. We rely on advanced processes and technologies to provide our vertically integrated volume manufacturing services. We strive continually to improve our manufacturing processes and have adopted a number of quality improvement and measurement techniques to monitor our performance. We work with our customers to anticipate their future manufacturing requirements and align our technology investment activities to meet their needs. We use our design expertise to develop product technology platforms that we can customize by incorporating other components and subassemblies to meet the needs of particular OEMs. These technologies enhance our ability to manufacture high value added, complex products, allowing us to continue to win business from existing and new customers.

      Original Design Manufacturing Solutions. As a result of customer demand, and their desire to contain research and development expenses, we have begun to offer product designs that the customer can either brand or integrate into their own system solution. In this model, we play the role of the original design manufacturer, or ODM, provider to the customer. For ODM products, we retain the intellectual property rights and earn royalty or licensing fees, in addition to the manufacturing revenue associated with building and shipping the product. Our current ODM portfolio covers several end markets, including enterprise computing,

      Continuing to Penetrate Diverse End Markets. We focus our marketing efforts on major end markets within the electronics industry. We have targeted markets that offer significant growth opportunities and for which OEMs sell complex products that are subject to rapid technological change, as the manufacturing of these products requires higher value added services. Our approach to our target markets is two-fold — we intend to strengthen our significant presence in the communications and computing markets, while also focusing on other under-penetrated target markets, including the medical, industrial and semiconductor capital equipment and defense and aerospace industries, many of which have not extensively relied upon EMS companies in the past. Our diversification across market segments and customers reduces our dependence on any particular market.

      Pursuing Focused Acquisition Strategy. We seek acquisitions that give us the opportunity to access new customers, manufacturing and service capabilities, technologies and geographic markets and further develop existing customer relationships. In some cases, OEMs may not be willing to outsource manufacturing without engaging in a divestiture transaction. In light of the current market environment, we are pursuing a disciplined acquisition strategy that focuses on OEM divestiture transactions in which we can augment existing strategic customer relationships with favorable supply agreement terms or build new relationships with customers in attractive end markets. We intend to continue to evaluate and pursue acquisition opportunities on a highly selective and strategic basis.

      Continuing to Seek Cost Savings and Efficiency Improvements. We seek to optimize our facilities to provide cost-efficient services for our customers. We provide extensive operations in lower cost locations, including Latin America, Eastern Europe, China and Southeast Asia, and we plan to expand our presence in these lower cost locations, as appropriate to meet the needs of our customers. We believe that we are well positioned to take advantage of future opportunities on a global basis as a result of our vertically integrated volume manufacturing strategy.

Our Products and Services

      We offer our OEM customers end-to-end services that span the entire product life cycle. Examples of products that we manufacture for OEMs include wireless and wireline communications switches, personal computers, high-end computers and servers, avionics, medical imaging systems and digital satellite set-top boxes. The manufacture of these products may require us to use all or some of our end-to-end services.

      Each element of our end-to-end services is described in greater detail below.

      Product Design and Engineering. Our design and engineering group, which we believe is one of the strongest in the EMS industry, provides customers with design and engineering services for initial product development, detailed product design and preproduction. This group complements our vertically integrated volume manufacturing capabilities by providing manufacturing design services for the manufacture of printed circuit boards, backplanes and enclosures. We provide initial product development and detailed product design and engineering services for products such as communications base stations, optical switches and modules, radio frequency amplifier modules, network switches, personal computers and servers.

	•	Initial Product Development. We provide a range of design and engineering services to customers to complement their initial product development efforts. During this phase, our design engineers work with our customers’ product development engineers to assist with design reviews and product concepts.
	•	Detailed Product Design. During the detailed product design phase, we work with our customers’ product development engineers to optimize product designs to improve the efficiency of the volume manufacturing of these products and reduce manufacturing costs. We further analyze product design to improve the ability of tests used in the manufacturing process to identify product defects and failures. We provide software development support for product development, including installing operating

Table of Contents

		systems on hardware platforms, developing software drivers for electronic devices, and developing diagnostic, production test and support software. We design components that are incorporated into our customers’ products, including printed circuit boards, backplanes and enclosures.
	•	Preproduction. After a detailed product design has been completed and the product is released for prototype production, we can build a prototype on a quick turn around basis. We then analyze the feasibility of manufacturing the product prototype and make any necessary design modifications to the prototype and test the prototype to validate its design. We also provide early-stage test development during the prototype phase. We evaluate prototypes to determine if they will meet safety and other standards, such as standards published by Underwriters Laboratories, an independent product safety testing and certification organization, and other similar domestic and international organizations. We review the material and component content of customers’ designs with a view to designing in alternative components that may provide cost savings. Our preproduction services help our customers reduce the time required to bring new products to market.
	•	Manufacturing Design Services. We provide our own designs for our vertically integrated system components and subassemblies, including:

	—	Printed Circuit Board and Backplane Design. We have a dedicated printed circuit board design group that designs and engineers complex printed circuit boards and backplanes. These printed circuit boards and backplanes incorporate high layer counts and large form factors and are used in complex products such as optical networking products and communications switches. Our designs also incorporate component miniaturization technologies and other advanced technologies that increase the number and density of components that can be placed on a printed circuit board. These technologies enable OEMs to provide greater functionality in smaller products. We also provide signal integrity engineering services, which involve the maintenance of the quality and integrity of high speed electrical signals as they travel through a system.
	—	Enclosure Design. We have a dedicated enclosure design group that designs and engineers complex enclosures. We can design custom enclosures to meet customer specifications and offer a range of proprietary designs tailored to particular applications. Our enclosure design services include the design of thermal management systems, which dissipate heat generated by the components within an enclosure. We design enclosures that are used in both indoor and outdoor environments. We also design enclosures that include both stackable and rackmount chassis configurations. In stackable configurations, component modules are stacked on top of each other, while in rackmount configurations, component modules slide into racks within the enclosure. Rackmount configurations often are used for complex products, such as communications switches that are frequently upgraded in the field by inserting new components. Our design engineers work with a range of materials, including metal, plastic and die-cast material. We design indoor and outdoor wireless base station cabinets, enclosures for high-end servers and data storage systems and enclosures for magnetic resonance imaging systems. We recently developed a sophisticated proprietary enclosure with a thermal management system for high density servers used for managed hosting in data center applications. We offer this enclosure platform to our customers who can then customize it with modules and subsystems designed and manufactured to their specifications. By using our common platform customers reduce their enclosure costs.

      Volume Manufacturing. Volume manufacturing includes our vertically integrated manufacturing services described in greater detail below.

	•	Printed Circuit Boards. Our ability to reliably produce printed circuit boards with high layer counts and narrow circuit track widths makes us an industry leader in complex printed circuit board fabrication. Printed circuit boards are made of laminated materials and contain electrical circuits and connectors that interconnect and transmit electrical signals among the components that make up electronic devices. We are among a small number of manufacturers that specialize in manufacturing complex multi-layer printed circuit boards. Multi-layering, which involves placing numerous layers of electrical circuitry on a single printed circuit board, expands the number of circuits and components

Table of Contents

		that can be contained on a printed circuit board and increases the operating speed of the system by reducing the distance that electrical signals must travel. Increasing the density of the circuitry in each layer is accomplished by reducing the width of the circuit tracks and placing them closer together on the printed circuit board. We are currently capable of efficiently producing printed circuit boards with up to 60 layers and circuit track widths as narrow as three mils. We use sophisticated circuit interconnections between certain layers to improve the performance of printed circuit boards. We have developed a proprietary material technology known as buried capacitance as well as various other processes that are designed to provide improved electrical performance and greater connection densities on printed circuit boards.
	•	Printed Circuit Board Assembly and Test. Printed circuit board assembly involves attaching electronic components, such as integrated circuits, capacitors, microprocessors, resistors and memory modules, to printed circuit boards. The most common technologies used to attach components to printed circuit boards are surface mount technology, or SMT, and pin-through-hole assembly, or PTH. SMT involves the use of an automated assembly system to solder components to the printed circuit board. In PTH, components are placed on the printed circuit board by insertion into holes punched in the circuit board. Components also may be attached using press-fit technology in which components are pressed into connectors affixed to the printed circuit board. We use SMT, PTH, press-fit as well as new attachment technologies that are focused on miniaturization and increasing the density of component placement on printed circuit boards. These technologies, which support the needs of our OEM customers to provide greater functionality in smaller products, include chip-scale packaging, ball grid array, direct chip attach and high density interconnect. We perform in-circuit and function testing of printed circuit board assemblies. In-circuit testing verifies that all components have been properly inserted and attached and that the electrical circuits are complete. We perform functional tests to confirm that the board or assembly operates in accordance with its final design and manufacturing specifications. We either design and procure test fixtures and develop our own test software, or we use our customers’ test fixtures and test software. In addition, we provide environmental stress tests of the board or assembly that are designed to confirm that the board or assembly will meet the environmental stresses, such as heat, to which it will be subject.
	•	Backplanes and Backplane Assemblies. Backplanes are very large printed circuit boards that serve as the backbones of sophisticated electronics products and provide interconnections for printed circuit boards, integrated circuits and other electronic components. We fabricate backplanes in our printed circuit board plants. Backplane fabrication is significantly more complex than printed circuit board fabrication due to the large size of backplanes. We manufacture backplane assemblies by attaching electronic components and printed circuit boards to backplanes using SMT, PTH, press-fit and other advanced component attachment technologies. We also perform in-circuit and functional tests on backplane assemblies. We manufacture complex optical backplanes that are 30 by 50 inches in size, have 48 layers and 65,000 holes for component placement, as well as our 10-gigabit copper-based backplane design. These are among the largest and most complex commercially manufactured backplanes, and we are one of a limited number of manufacturers of these complex backplanes.
	•	Enclosures. Enclosures are cabinets that house and protect complex and fragile electronic components, modules and subsystems. Our enclosure manufacturing services include fabrication of cabinets and chassis and racks that are placed inside the cabinets to hold the subassemblies and modules that comprise electronic devices. We integrate power and thermal management subsystems into our enclosures. We manufacture a broad range of enclosures with a broad range of materials including metal, plastics and die cast materials. Enclosures we manufacture range from basic enclosures, such as enclosures for personal computers, to large and highly complex enclosures, such as those for indoor and outdoor communications base station products. We have recently developed a proprietary enclosure with a thermal management system designed for high density servers for managed hosting in data center applications. Our customers can have their unique products built on this platform by inserting their proprietary modules and subsystems.

	•	Memory Modules. Memory modules are integrated subsystems that use industry standard integrated circuits including digital signal processors, or DSPs, non-volatile flash memory and random access memory, or RAM. These modules consist of standard products that are sold for a range of applications to a broad base of customers and custom modules that are built for use in a particular OEM’s product or system. We design and manufacture a variety of modular solutions, including standard and custom DSP, flash memory modules and RAM. In addition, we are a leading supplier of solutions to increase memory component density on printed circuit boards. We offer advanced NexMod memory modules that contain multiple memory layers vertically stacked and mounted to a printed circuit board. NexMod solutions are tailored for network infrastructure and complex server applications. We also provide innovative DDRI and DDRII DRAM modules utilizing stacked CSP technology offering high densities and small form factors. We provide custom module solutions including mixed memory and our proprietary foldable rigid assembly microelectronics module, or FRAMM. Our FRAMM technology incorporates two memory modules with a flexible cable between them. The module folds over itself, effectively doubling the memory capacity that can be plugged into a memory slot. We integrate both standard and custom modules in products that we manufacture.

      Final System Assembly and Test. We provide final system assembly and test in which assemblies and modules are combined to form complete, finished products. We often integrate printed circuit board assemblies manufactured by us with enclosures, cables and memory modules that we also produce. Our final assembly activities also may involve integrating components and modules that others manufacture. The complex, finished products that we produce typically require extensive test protocols. Our test services include both functional and environmental tests. We also test products for conformity to applicable industry, product integrity and regulatory standards. Our test engineering expertise enables us to design functional test processes that assess critical performance elements, including hardware, software and reliability. By incorporating rigorous test processes into the manufacturing process, we can help to assure customers that their products will function as designed. Products for which we currently provide final system assembly and test include wireless base stations, wireline communications switches, optical networking products, high-end servers and personal computers.

      Direct Order Fulfillment. We provide direct order fulfillment for our OEM customers. Direct order fulfillment involves receiving customer orders, configuring products to quickly fill the orders and delivering the products either to the OEM, a distribution channel (such as a retail outlet) or directly to the end customer. We manage our direct order fulfillment processes using a core set of common systems and processes that receive order information from the customer and provide comprehensive supply chain management, including procurement and production planning. These systems and processes enable us to process orders for multiple system configurations, and varying production quantities, including single units. Our direct order fulfillment services include BTO and CTO capabilities. BTO involves building a system having the particular configuration ordered by the OEM customer. CTO involves configuring systems to an end customer’s order. The end customer typically places this order by choosing from a variety of possible system configurations and options. We are capable of meeting a 48 to 72 hour turn-around-time for BTO and CTO by using advanced

      After-Market Product Service and Support. We provide a range of after-market product service and support services, including replacing products at customer locations, product repair, re-manufacturing and maintenance at repair depots, logistics and parts management, returns processing, warehousing and engineering change management. We also provide support services for products that are nearing the end of their life cycles. These end-of-life support services involve both customer support and manufacturing support activities. We support the customer by providing software updates and design modifications that may be necessary to reduce costs or design-in alternative components due to component obsolescence or unavailability. Manufacturing support involves test engineering support and manufacturability enhancements. We also assist with failure product analysis, warranty and repair and field service engineering activities.

Global Supply Chain Management

      Supply chain management involves the planning, purchasing and warehousing of product components. The objective of our supply chain management services is to reduce excess component inventory in the supply chain by scheduling deliveries of components on a just-in-time, as-and-when-needed basis. We use sophisticated production management systems to manage our procurement and manufacturing processes in an efficient and cost effective manner. We collaborate with our customers to enable us to respond to their changing component requirements for their products and to reflect any changes in these requirements in our production management systems. These systems often enable us to forecast future supply and demand imbalances and develop strategies to help our customers manage their component requirements. Our enterprise-wide software systems provide us with company-wide information regarding component inventories and orders to standardize planning and purchasing at the plant level. These systems enable us to transfer product components between plants to respond to changes in customer requirements or to address component or other raw material shortages.

      We purchase large quantities of electronic components and other raw materials from a range of suppliers. As a result, we often receive volume discounts or other favorable terms from suppliers, which can enable us to provide our customers with greater cost reductions than they can obtain themselves. Our supplier relationships often enable us to obtain electronic components and other raw materials that are in short supply or return excess inventories to suppliers even when they are not contractually obligated to accept them.

Our End Markets

      We have targeted markets that offer significant growth opportunities and for which OEMs sell complex products that are subject to rapid technological change, as the manufacturing of these products requires higher value added services. We believe that markets involving complex, rapidly changing products offer us opportunities to produce products with higher margins because these products require higher value added manufacturing services and may also include our advanced vertically integrated components. Our approach to our target markets is two-fold — we intend to strengthen our significant presence in the communications and computing markets, while also focusing on other under-penetrated target markets, including the medical, automotive, industrial and semiconductor capital equipment and defense and aerospace industries, many of which have not extensively relied upon EMS companies in the past.

      Computing:     Personal and Business (Enterprise) Computing and Storage Systems. We provide services for OEMs of personal computer, or PC, systems, enterprise computing, and storage systems.

      We provide services to multiple major PC manufacturers. These services include primarily BTO and CTO manufacturing of desktop PC systems serving primarily the enterprise markets. Our PC manufacturing plants can build and configure systems and have them ready for shipment within 48 to 72 hours of receipt of a customer order. These plants are typically located in the geographic region to which the finished system will be shipped to rapidly deliver finished products. We manufacture a wide variety of desktop and laptop PCs and other PC components for our customers, including Dell, HP and IBM.

      We also provide services to the storage and server markets. Our expertise in manufacturing products for the storage and server markets stems from our technological capabilities and vertical integration. We are also the leading vertically integrated supplier of complex, multilayer printed circuit boards and backplanes, and many high-end computer designs incorporate these components. We have developed a proprietary enclosure design for high density servers used in data center applications. High-end computing products we manufacture include complex, fault tolerant servers and enterprise storage. Our customers in the storage and server markets include EMC, HP, IBM and Sun.

      Multimedia. We manufacture digital satellite set-top boxes, personal video recorders, digital home gateways and internet protocol entertainment devices. For our multimedia OEM customers, we manage the production process for multimedia products, including product design and engineering, test development, supply chain management, manufacturing of printed circuit boards and assemblies, final system assembly and test, and direct order fulfillment, including our BTO and CTO capabilities. Our major multimedia customers include EchoStar, Nokia, and Royal Philips Electronics.

      Industrial and Semiconductor Systems. Our expertise in manufacturing industrial instrumentation products includes production of semiconductor capital equipment, front-end environmental chambers, computer controllers, and test and inspection equipment. We also have significant experience manufacturing scanning equipment and devices, flat panel display test and repair equipment, optical inspection and x-ray equipment for use in the printed circuit board assembly industry, and deep ultraviolet photolithography equipment. Our industrial and semiconductor systems customers include GE and Honeywell International Inc, or Honeywell.

      Defense and Aerospace. In December 2001, we merged with SCI Systems, Inc., or SCI. SCI began operations as Space-Craft, Inc., in the early 1960’s and was then principally a supplier to the defense and aerospace industries. We continue to offer our end-to-end services to the defense and aerospace industry. We believe that this industry currently represents a significant growth opportunity due to increased defense spending, as well as the growing desire of defense and aerospace OEMs to outsource non-core manufacturing activities to reduce costs. Our experience in serving the aerospace industry, as well as our product design and engineering capabilities, represent key competitive strengths for us in the defense and aerospace market. Defense and aerospace products that we manufacture include avionics systems, weapons guidance systems, cockpit communications systems, spread spectrum communications systems, and space systems. Key defense and aerospace customers include The Boeing Company, Honeywell, Lockheed Martin Corporation and Raytheon Company.

      Medical. We provide comprehensive manufacturing and related services to the medical industry, including design and regulatory approval support. The manufacturing of products for the medical industry requires compliance with domestic and foreign regulations, including the Food and Drug Administration’s, or FDA’s, quality system regulations and the European Union’s medical device directive. In addition to complying with these standards, our medical manufacturing facilities comply with ISO 13485 (formerly EN 46002) and ISO 9001:2000. Medical products that we manufacture include magnetic resonance imaging equipment, blood glucose meters, computer tomography scanners, respiration monitors, ventilators, anesthesia

      Automotive. In recent years, the electronics content in automobiles has increased substantially as new entertainment, wireless communication and navigation systems are being offered as standard features or factory options. We believe that this increased usage of electronic devices in automobiles will continue, and that there will be significant opportunities for EMS companies to manufacture automotive electronics. Accordingly, we have formed an automotive products group to focus on these opportunities.

Customers

      Our ten largest customers (listed in alphabetical order) are Alcatel, Dell, EchoStar, Ericsson, Hitachi, HP, IBM, Nokia, Nortel and Roche.

      A relatively small number of customers historically have been responsible for a significant portion of our net sales. Sales to our ten largest customers accounted for 68.5% of our fiscal 2003 net sales and 65.8% of our fiscal 2002 net sales. For fiscal 2003, our two largest customers, IBM and HP, accounted for approximately 28.8% and 9.6%, respectively, of our net sales.

      We seek to establish and maintain long-term relationships with our customers and have served many of our principal customers for several years. Historically, we have had substantial recurring sales from existing customers. We have also expanded our customer base through acquisitions and our marketing and sales efforts. We have been successful in broadening relationships with customers by providing vertically integrated products and services, as well as multiple products and services in multiple locations.

      We typically enter into supply agreements with our major OEM customers with terms ranging from three to five years. Many of these supply agreements were entered into in connection with divestiture transactions, which are transactions in which we also acquire plants, equipment and inventory from the OEM. In these divestiture-related supply agreements, the customer typically agrees to purchase its requirements for particular products in particular geographic areas from us. Our OEM customer supply agreements that were not entered into in connection with divestitures typically do not require the customer to purchase their product requirements from us, and in these cases customers may have alternate sources of supply available to them. Our supply agreements with our OEM customers generally do not obligate the customer to purchase minimum quantities of products. However, the customer typically remains liable for the cost of the materials and components that we have ordered to meet the customer’s production forecast but which are not used, provided that the material was ordered in accordance with an agreed-upon procurement plan. In some cases, the procurement plan contains provisions regarding the types of materials for which our customers will assume responsibility. Our supply agreements typically contain provisions permitting cancellation and rescheduling of orders upon notice and subject, in some cases, to cancellation and rescheduling charges. Order cancellation charges typically vary by product type and depend upon how far in advance of shipment a customer notifies us of the cancellation of an order. In some circumstances, our supply agreements with customers provide for cost reduction objectives during the term of the agreement.

      We generally do not obtain firm, long-term commitments from our customers under supply agreements. As a result, customers can cancel their orders, change production quantities or delay orders. Uncertain economic conditions and our general lack of long-term purchase contracts with our customers make it difficult for us to accurately predict revenue over the longer-term. Even in those cases where customers are contractually obligated to purchase products from us or repurchase unused inventory from us that we have ordered for them, we may elect not to immediately enforce our contractual rights because of the long-term nature of our customer relationships and for other business reasons, and instead may negotiate accommodations with customers regarding particular situations.

Backlog

      At September 27, 2003, our backlog was $2.1 billion, compared to $2.7 billion at September 28, 2002. Backlog consists of purchase orders received, including, in some instances, forecast requirements released for production under customer contracts. Cancellation and postponement charges generally vary depending upon the time of cancellation or postponement, and a portion of our backlog may be subject to cancellation or postponement without significant penalty. Customers may cancel scheduled deliveries and backlog may therefore not be a meaningful indicator of future financial results.

Marketing and Sales

      Our corporate marketing, sales and customer service staff consists of approximately 800 people. Our sales efforts are organized and managed on a regional basis, with regional sales managers in geographic regions in the United States and internationally.

      We develop relationships with our customers and market our vertically integrated volume manufacturing services through our direct sales force and customer support specialists. Our sales resources are directed at multiple management and staff levels within target accounts. Our direct sales personnel work closely with the customers’ engineering and technical personnel to better understand their requirements. Our marketing and sales staff supports our business strategy of providing end-to-end services by encouraging cross-selling of vertically integrated volume manufacturing services and component manufacturing across a broad range of major OEM products. To achieve this objective, our marketing and sales staff works closely with our various manufacturing and design and engineering groups and engages in marketing and sales activities targeted towards key customer opportunities.

      Our key customer accounts are managed by a dedicated account team, including a global business manager directly responsible for account management. Global business managers coordinate activities across divisions to effectively satisfy customer requirements and have direct access to our senior management to quickly address customer concerns. Local customer account teams further support the global teams and are linked by a comprehensive communications and information management infrastructure. In addition, our senior management, including our chief executive officer, Jure Sola, and our president and chief operating officer, Randy Furr, are heavily involved in customer relations and devote significant attention to broadening existing, and developing new, customer relationships.

Competition

      We face competition from other major global EMS companies such as Celestica, Inc., Flextronics International Ltd., Jabil Circuit, Inc. and Solectron Corporation, as well as other EMS companies that often have a regional or product, service or industry specific focus. In addition, our potential customers may also compare the benefits of outsourcing their manufacturing to us with the merits of manufacturing products themselves.

      We compete with different companies depending on the type of service or geographic area. We believe that the primary basis of competition in our target markets is manufacturing technology, quality, responsiveness, the provision of value-added services and price. To remain competitive, we must continue to provide technologically advanced manufacturing services, maintain quality levels, offer flexible delivery schedules, deliver finished products on a reliable basis and compete favorably on the basis of price. We believe that our primary competitive strengths include our ability to provide global end-to-end services, our product design and engineering resources, advanced technologies, high quality manufacturing assembly and test services, customer focus, expertise in serving diverse end markets and an experienced management team.

      In addition to EMS companies, we also compete, with respect to certain of the EMS services we provide, with ODMs. These companies, typically based in Asia, design products and product platforms that are then sold to OEMs, system integrators and others who configure and resell them to end users. To date, ODM penetration has been greatest in the personal computer, including both desktop and notebook computers, and server markets.

Intellectual Property

      We hold various United States and foreign patents primarily related to printed circuit boards, methods of manufacturing printed circuit boards, and enterprise computing. For other proprietary processes, we rely primarily on trade secret protection. We also have registered trademarks in the United States and many other countries throughout the world. As the level of ODM services we provide increases, intellectual property will become of greater importance to our business.

      Although we do not believe that our current trademarks, manufacturing processes or patents infringe on the intellectual property rights of third parties, we cannot assure you that third parties will not assert infringement claims against us in the future. If such an assertion were to be made, it may become necessary or useful for us to enter into licensing arrangements or to resolve such an issue through litigation. However, we cannot assure you that such license rights would be available to us on commercially acceptable terms if at all or that any such litigation would be resolved favorably. Additionally, such litigation could be lengthy and costly and could materially harm our financial condition regardless of the outcome of such litigation.

      We are currently a party to an intellectual property dispute in which Gemstar-TV Guide International, Inc., or Gemstar, and StarSight Telecast, Inc., or StarSight, alleged, with respect to SCI, certain violations of the Tariff Act of 1930, including patent infringement, in the importation of set-top multimedia boxes manufactured outside the United States by SCI for EchoStar, another party in the case. This proceeding was filed before the U.S. International Trade Commission, or ITC, in February 2001. Gemstar and StarSight filed a related patent infringement case against SCI in the United States District Court for the Northern District of Georgia in February 2001, which is currently pending. A trial at the ITC before an administrative law judge concluded in December 2001. On June 21, 2002, the presiding administrative law judge issued his final initial determination in the proceedings. The judge found that the patent claims in issue were not infringed by the respondents, including SCI, and found no violation by the respondents, including SCI, of the Tariff Act. In July 2002, Gemstar filed a petition for review of the administrative law judge’s determinations with the ITC. In August 2002, the ITC upheld the administrative law judge’s finding that the respondents, including SCI, had not violated the Tariff Act. Gemstar appealed the ITC’s determination to the U.S. Court of Appeals for the Federal Circuit. Oral arguments were heard by the U.S Court of Appeals on October 10, 2003 and the appeal is now under submission for decision to a panel of the Federal Circuit. If the Court of Appeals subsequently determines that SCI infringes Gemstar’s and StarSight’s patents, such determination could prohibit the importation of infringing products into the United States. To the extent that our customer, EchoStar, cannot “design around” the allegedly infringing design or build the product in the United States thereby avoiding the importation of potentially infringing products, revenue from this customer, and potentially other like customers using the allegedly infringing technology, could be at risk. Any “design around” would by necessity originate with EchoStar. Labor costs in the United States may make production of allegedly infringing products in the United States uncompetitive. We believe we have meritorious defenses to this action, and therefore we believe that the outcome of this matter will not materially harm our business.

Environmental Controls

      We are subject to a variety of local, state and federal environmental laws and regulations in the United States, as well as foreign laws and regulations, relating to the treatment, storage, use, discharge, emission and disposal of chemicals, solid waste and other hazardous materials used during our manufacturing processes, as well as occupational safety and health laws, and product take back, product labeling and product content requirements. Proper waste disposal is a major consideration in particular for printed circuit board manufacturers because metals and chemicals are used in the manufacturing process. Water used in the printed circuit board manufacturing process must be treated to remove metal particles and other contaminants before it can be discharged into municipal sanitary sewer systems.

      In addition, although the electronics assembly process generates significantly less wastewater than printed circuit board fabrication, maintenance of environmental controls is also important in the electronics assembly process because such operations can generate lead dust. We are undertaking remediation of lead dust in the

Table of Contents

      Asbestos containing materials, or ACM, are present at several of our manufacturing facilities. Although the ACM is being managed and controls have been put in place pursuant to ACM operations and maintenance plans, the presence of ACM could give rise to affirmative remediation obligations and other liabilities. No third-party claims relating to ACM have been brought at this time.

      Each plant, to the extent required by law, operates under environmental permits issued by the appropriate governmental authority. These permits must be renewed periodically and are subject to revocation in the event of violations of environmental laws. Any such revocation could require us to cease or limit production at one or more of our facilities, thereby having an adverse impact on our results of operations.

      We have incurred liabilities associated with environmental contamination at our current and former facilities, and those of the companies that we have acquired. These liabilities include ongoing investigation and remediation activities at a number of sites, including our facilities located in Irvine, California (acquired as part of our acquisition of Elexsys), Owego, New York (a current facility of our Hadco subsidiary), Derry, New Hampshire (a current facility of our Hadco subsidiary) and Fort Lauderdale, Florida (a former facility of our Hadco subsidiary). Currently, we are unable to anticipate whether any third-party claims will be brought against us for the existence of such contamination. There can be no guarantee that third-party claims will not arise and will not result in material liability to us. In addition, there are several sites, including our facilities in Wilmington, Massachusetts, Clinton, North Carolina, Brockville, Ontario and Gunzenhausen, Germany that are known to have groundwater contamination caused by a third party, and that third party has provided indemnity to us for the liability. Although we cannot guarantee you that we will not incur liability for clean-up costs or expenses at any of these sites, we have no reason to believe that such liability will occur and that it will be material to our business.

      We have also been named as a potentially responsible party at several contaminated disposal sites including the Casmalia Resources site, as a result of the past disposal of hazardous waste by companies we have acquired or by our corporate predecessors. Although liabilities for such historic disposal activities have not materially affected our financial condition to date, we cannot guarantee you that past disposal activities will not result in liability that will materially affect us in the future.

      We use an environmental consultant to assist us in evaluating the environmental liabilities of the companies that we acquire as well as those associated with our ongoing operations, site contamination issues and historical disposal activities in order to establish appropriate accruals in our financial statements. We have also undertaken a process of re-evaluating and updating the reserves over time. As of September 27, 2003, based on the evaluations of our consultants, we have accrued $21.1 million for such environmental liabilities. Although we believe these accruals are adequate, we cannot be certain that environmental liabilities will not exceed the accrued amounts.

      Due to the large number of mergers and acquisitions we have undertaken, we have a number of facilities that have different environmental management systems, auditing programs and policies in place. We are in the process of developing corporate-wide standardized environmental management systems, auditing programs and policies to make these matters easier to manage.

Employees

      As of September 27, 2003, we had 45,008 full-time employees, including 42,457 in manufacturing and engineering, 782 in corporate marketing and sales and 1,769 in corporate general administration and finance. None of our U.S. employees are represented by a labor union. In certain international locations, particularly in Western Europe, our employees are represented by labor unions on either a national or plant level. Western European countries also often have mandatory legal provisions regarding terms of employment, severance

      Facilities. Our customers market numerous products throughout the world and therefore need to access manufacturing services on a global basis. To enhance our EMS offerings, we seek to locate our facilities either near our customers and our customers’ end markets in major centers for the electronics industry or, where appropriate, in lower cost locations. Many of our plants located near customers and their end markets are focused primarily on final system assembly and test, while plants located in lower cost areas are engaged primarily in less complex component and subsystem manufacturing and assembly.

      As of September 27, 2003, we manufacture products in approximately 100 decentralized plants, consisting of more than 68 electronics assembly facilities, six printed circuit board fabrication facilities, six cable assembly facilities, 21 enclosure assembly facilities, as well as other specialized manufacturing facilities, located both domestically and internationally. Our domestic plants are located in key electronics industry centers including Silicon Valley, Southern California, New England, Texas, Northern Alabama, the Research Park Triangle area, New York, as well as in several other locations. Internationally, we have plants in Australia, Latin America (Brazil and Mexico), Canada, Western Europe (United Kingdom, Ireland, France, Germany, Spain, Sweden, and Finland), Eastern Europe (Hungary), Israel and Asia (Peoples’ Republic of China, Japan, Malaysia, Singapore, and Thailand). For fiscal 2003, approximately 69.6% of our net sales were from operations outside of the United States.
