          Although our current business development focus is based on the end-market sectors noted above, we evaluate our financial performance and allocate our resources on a geographic basis (see Note 12 in Notes to Consolidated Financial Statements regarding our operating segments).
Materials and Suppliers
          We primarilytypically purchase raw materials, including printed circuit boards and electronic components, from manufacturers and distribution companies.as well as from electronic distributors. In addition, we may alsooccasionally purchase components from customers. The key electronic components we purchase include printed circuit boards, specialized components such as application-specific integrated circuits, semiconductors, interconnect products, electronic subassemblies (including memory modules, power supply modules and cable and wire harnesses), inductors, resistors and capacitors. Along with these electronic components, we also purchase components for useused in higher-level assembly and manufacturing. These components include injection-molded plastic,plastics, pressure-formed plastics, vacuum-formed plastics, sheet metal fabrications, aluminum extrusions, die castings and various other hardware and fastener components. TheseAll of these components range from standard to highly customized and they vary widely in terms of market volatilityavailability and price. From time to time, allocation of components
          Occasional component shortages and subsequent allocations by suppliers becomesare an integralinherent part of the electronics industry, and shortages can occur with respect to particular components. In response, weindustry. We actively manage our business in a way that seeksto try to minimize our exposure to materialsmaterial and component shortages. We have developed a corporate sourcing and procurement organization whose primary purpose is to develop supply-chain sources and create strong supplier alliances to ensure, as much as possible, a steady flow of components at competitive prices. Because we design products and therefore can influence whatthe selection of components are used in some new products, component manufacturers of components often provide us with priority access to a supply of materials and components, even during times of shortages. We have also established and continue to expand our strategic relationships with international purchasing offices, and we attempt to leverage our design position with suppliers. Beyond this, we have undertaken a series of initiatives, including the utilization of in-plant stores, point-of-use programs, assured supply programs and other efforts. All of these undertakings seekefforts to improve our overall supply chain flexibility and to accommodate the current marketplace. SALES AND MARKETING We market our servicesflexibility.
New Business Development
          Our new business development is directed primarily through our sales and marketing organization. During fiscal 2004, we reorganized our sales and marketing effortsan internal effort organized around key customer end-markets, or market sectors: namely, networking/ datacommunications, medical and industrial.sectors.

Competition
          The market for the products and services we provide is highly competitive. We compete primarily on the basis of meeting the unique needs of our customers, and providing flexible solutions, timely order fulfillment and strong engineering, testing and production capabilities, technological capabilities and the capacity for responsiveness, quality and price. There arecapabilities. We have many competitors in the electronics design and assembly industry. Larger and more geographically diverse competitors have substantially more resources than we do. Other, smaller competitors primarily compete only in specific sectors, typically within limited geographical areas. We also compete against companies that design or manufacture items in-house rather than by outsourcing.in-house. In addition, we compete against foreign, low labor costlow-labor-cost manufacturers. This foreign, low labor costlow-labor-cost competition tends to focus on commodity and consumer-related products, which is not our primary focus. INTELLECTUAL PROPERTY
Intellectual Property
          We own various service marks, including "Plexus,"“Plexus,” and "Plexus,“Plexus, The Product Realization Company." Although we own certain patents, they are not currently material to our business. We do not have any material copyrights. INFORMATION TECHNOLOGY We began to implement in
Information Technology
          In fiscal 2001, we began implementation of an enterprise resource planning ("ERP")ERP platform. This ERP platform is intended to augmentaugments our other management information systems and includes software from J.D. Edwards (now part of Peoplesoft)Oracle Corporation) and several other vendors. The ERP platform includes various software systems to enhance and standardize our ability to globally translate information from multiple production facilities into operational and financial information and create a consistent set of core business applications at our worldwide facilities.facilities worldwide. We believe the related software licenses are of a general commercial character on terms customary for these types of agreements. During fiscal 2004,2005, we converted one additional manufacturing facility to the common ERP platform and now manage a significant majority of our net sales on the common ERP platform. We anticipate converting at least one more facilityplan to extend the common ERP platform to the ERP platform in fiscal 2005. Theremaining Plexus sites over the next two years; however, the conversion timetable for the remaining Plexus sites and remaining project scope remainare subject to change based upon our evolving needs and sales levels. ENVIRONMENTAL COMPLIANCEneeds.
Environmental Compliance
          We are subject to a variety of environmental regulations relating to the use, storage, discharge and disposal of hazardous chemicals used during our manufacturing process. Although weWe believe that we are in compliance with all federal, state and local environmental laws and do not anticipate any significant expenditures in maintaining our compliance,compliance; however, there can be no assurancesassurance that violations will not occur which could have a material adverse effect on our financial results. EMPLOYEES
Employees
          Our employees are one of our primary strengths, and we make a considerable effortseffort to maintain a well-qualified staff.and motivated work force. We have been able to offer enhanced career opportunities to many of our employees. Our human resources department identifies career objectives and monitors specific skill developmentdevelopments for employees with potential for advancement. We invest at all levels of the organization to ensure that employees are well trained. We have a policy of involvement and consultation with employees in every facility and strive for continuous improvement at all levels.
          We employ approximately 6,0006,800 full-time employees. Given the quick response times required by our customers, we seek to maintain flexibility to scale our operations as necessary to maximize efficiency. To do so, we use skilled temporary labor in addition to our full-time employees. In Europe, approximately 70 of our employees are covered by union agreements. These union agreements are typically renewed at the beginning of each year, although in a few cases these agreements may last two or more years. Our employees in the United States, United Kingdom,Malaysia, China Malaysia and Mexico are not covered by union agreements. We have no history of labor disputes at any of our facilities. We believe that our employee relationships are good.

ITEM 3. LEGAL PROCEEDINGS
          As we have previously disclosed, the Company (along with hundreds ofmany other companies) has been sued by the Lemelson Medical, EducationalEducation & Research Foundation Limited Partnership ("Lemelson"(“Lemelson”) forrelated to alleged possible infringement of certain Lemelson patents. The complaint, which is one of a series of complaints by Lemelson against hundreds of companies, seeks injunctive relief, treble damages (amount unspecified) and attorneys'attorneys’ fees. The Company has obtained a stay of action pending developments in other related litigation. InOn January 23, 2004, the judge in the other related litigation ruled for the parties challenging the patents,against Lemelson, thereby declaring the Lemelson patents unenforceable and invalid. Lemelson has appealed this ruling. Ifruling and on September 9, 2005, the verdict is upheldU.S. Court of Appeals for the Federal Circuit affirmed the lower Court’s decision ruling that the Lemelson patents are unenforceable, and on November 16, 2005 denied a petition for rehearing. Lemelson may appeal it would likely result in dismissal of claimsthis decision to the U.S. Supreme Court. The lawsuit against the Company. The Company's lawsuitCompany remains stayed pending the outcome of that appeal. A decision on the appealoutcome.
          The Company is not expected until some time in 2005, at the earliest. Even if the verdict is not upheld, the Company believes the vendors from which patent-related equipment was purchased may be required to contractually indemnify the Company. However, based upon the Company's observation of Lemelson's actions in other parallel cases, it appears that Lemelson's primary objective is to cause defendants to enter into license agreements. Although the patents at issue would theoretically relate to a significant portion of our net sales, even if the verdict in the other case is overturned and a judgment is rendered in our case and/or a license fee required, it is the opinion of management that such judgment or fee would not be material to the Company's financial position, results of operations or cash flows. Lemelson Medical, Educational & Research Foundation Limited Partnership vs. Esco Electronics Corporation et al, US District Court for the District of Arizona, Case Number CIV 000660 PHX JWS (2000). We are party to other certain other lawsuits in the ordinary course of business. Management does not believe that these proceedings, individually or in the aggregate, will have a material adverse effect on the Company'sCompany’s financial position, results of operations or cash flows.

EXECUTIVE SUMMARY
          Our primary objective at the outset offocus as we entered fiscal 20042005 was to returnimprove the company to profitability. The restructuring actionsCompany’s profitability primarily by attaining profitable growth in revenues while improving operational efficiencies, including better management of working capital. Revenues in fiscal 2005 increased 18 percent over the prior year, and gross margins, both in absolute dollars and as a percentage of revenues, improved quarter-over-quarter throughout the fiscal year. Gross margins in the first half of the preceding years had lowered our cost structure and improved capacity utilization. We also strengthened and reorganized our sales, marketing and business development function to drive sales growth and strengthen our customer portfolio. As a result of this focus and improved industry demand, especially within the networking/datacommunication industry, we achieved fiscal 2004 sales growth of 29 percent, without making acquisitions. We believe this to be the highest organic growth rate within the EMS industry. This growth rate was well above the approximately 18 percent annual growth rate expected by various industry surveys for the broad EMS industry, so we believe we have consequently gained market share. The rapid sales growth in fiscal 2004 placed additional strains on the organization, and consequently, gross margins and overall profitabilityyear were adversely affected by manufacturing inefficiencies and material control issues in our facility in Juarez, Mexico (“Juarez”). In addition, we incurred anticipated start-up losses associated with a new facility in Penang, Malaysia (“Penang”), which attained profitability only later in the fiscal year. Profitability was enhanced by the economies of scale associated with higher new program-related transition and training expenses,revenues than in the prior year, as well as the needcontinued application of lean manufacturing initiatives.
          Better inventory management allowed us to gain experience manufacturing new programs. Year-over-year, we addedincrease revenues without substantially increasing inventory levels, and trained approximately 1,300 new production-related employees at sites located aroundinventory turnover increased to 6.4 from the world, principallyprior year’s 6.2. We also negotiated more favorable payment terms with many of our suppliers, which increased accounts payable balances and improved our cash conversion cycle. Our focus on improving working capital management allowed us to finance revenue growth internally and still generate positive cash flows from operations resulting in Asiaa $63.8 million increase in cash and Mexico, in order to support our sales growth. In addition, we purchased and substantially outfitted a second manufacturing and engineering facility in Penang, Malaysia ("Penang"). This expansion was driven by additional demand from our customers for more production in this relatively low-cost country.short-term investments.
          As we look toenter fiscal 2005, our primary objective2006, we are encouraged by the improved operational metrics achieved in the prior year. Our goal is to continue to improve profitability. We expectfinancial performance and to achieve this goal with improvements in capacity utilization and operating efficiencies through a combination of moderate sales expansion and lean manufacturing and inventory management initiatives. We also recently announced restructuring plans to close our Bothell, Washington ("Bothell") manufacturing and engineering facility in mid-fiscal 2005, which we expect will improve overall capacity utilization once the facility is closed. Additionally, we will remain intensely focused on working capital utilization andearn an after-tax return on capital employed.employed greater than our estimated 15 percent weighted average cost of capital. This, we believe, can be achieved by expanding operating margins and accelerating our capital employed turnover through further improvements in the management of working capital. Based on customer indications of expected demand and management estimates of new program wins, our internal projections currently anticipate full fiscal 20052006 sales growth of approximately 15 percent to 18 percent. We currently expect first quarter of fiscal 20052006 sales to be in the range of $280$315 million to $290$325 million; however, our results will ultimately depend on the actual levels of customer order levels. We anticipate thatorders.
FACILITY CLOSURES/ACQUISITIONS
          In fiscal 2005, we closed our Bothell engineering and manufacturing facility and transitioned the initial stages of production in the newremaining customer programs to other Plexus sites.
          In fiscal 2004, we purchased a second manufacturing facility in Penang, will impair our overall profitability through at leastwhich commenced manufacturing activities in the first halfquarter of fiscal 2005. Additionally, incremental costs associated with transitioning programsThe expansion was driven by additional demand from our recently announced closure of our Bothell facility and continued near-term weakness at a couple of our sites will also impair our overall profitabilitycustomers for more production in the first half of fiscal 2005. FACILITY CLOSURES/ACQUISITIONSthis relatively low-cost country. In fiscal 2004, we closed our PCB design operations in Hillsboro, Oregon ("Hillsboro"(“Hillsboro”) and announced plans to close our Bothell facility by the second quarter ofin fiscal 2005. In addition, we sold a small PCB design operationsoperation in Tel Aviv, Israel to a group of former employees; however, this transaction did not have a material impact on our consolidated financial statements.
          In fiscal 2003, we closed our manufacturing facilities in San Diego, California ("(“San Diego"Diego”) and Richmond, Kentucky ("Richmond"(“Richmond”), and ceased production in our oldest facility in Neenah, Wisconsin ("Neenah"(“Neenah”). In addition, we sold our PCB design operations in Nashua, New Hampshire to a group of former employees; however, this transaction did not have a material impact on our consolidated financial statements. In January 2002, we acquired certain assets of MCMS, Inc. ("MCMS"), an electronics manufacturing services provider, for approximately $42.0 million in cash. The assets purchased from MCMS include manufacturing operations in Penang, Malaysia; Xiamen, China; and Nampa, Idaho. The consideration for this acquisition did not include the assumption of any interest-bearing debt, but included the assumption of total liabilities of approximately $7.2 million. The results from MCMS's operations are reflected in our financial statements from the date of acquisition. No goodwill resulted from this acquisition. We incurred approximately $0.3 million of acquisition costs in the second quarter of fiscal 2002 associated with the acquisition of MCMS. 10

          Net sales for the fiscal year ended October 1, 2005 increased 18 percent from the year ended September 30, 2004. The increase reflects increased growth in all sectors, particularly in the wireless infrastructure, wireline/networking, industrial and medical sectors.
          The net sales growth in the wireline/networking and medical sectors was primarily associated with Juniper and GE, respectively, our largest customers. Net sales growth in the wireline/networking sector is expected to continue in fiscal 2006 based on current customer forecasts and the expected start-up of new programs. In the medical sector, we anticipate that net sales may decline in fiscal 2006 due largely to uncertainty over future manufacturing for a key customer in the United Kingdom (see further discussion below under “Fiscal 2005 Restructuring and Impairment CostsGoodwill Impairment”).
          The growth in the wireless infrastructure and industrial sectors reflect new program wins from both new and existing customers. Based on current customer forecasts, we anticipate that net sales in the industrial sector will be relatively flat in fiscal 2006. Although we achieved fiscal 2005 net sales growth in the wireless infrastructure sector, a key end-customer of one of our customers in this sector recently exercised an option to manufacture some of our customer’s product. The impact of this event on us is unknown; however, the event prompts a less optimistic outlook for the wireless infrastructure sector in the first half of fiscal 2006.
          In the defense/security/aerospace sector, we obtained new programs during fiscal 2005, which we anticipate will result in fiscal 2006 net sales growth in this sector as we move beyond start-up production for these new customers.
          Net sales for the fiscal year ended September 30, 2004 increased 29 percent from the year ended September 30, 2003. The increase reflects strengthened end-market demand particularly in the networking/ datacommunications,wireline/networking, wireless infrastructure, medical and industrialdefense/security/aerospace sectors, as well as new program wins from both new and existing customers.customers in all sectors. Net sales growth in the computer industry declined to 6 percent of consolidated net sales in fiscal 2004 from 12 percent of consolidated net sales in fiscal 2003wireline/networking sector was primarily associated with Juniper, our largest customer. The industrial/commercial sector remained relatively flat due primarily to weakened end-market demand from two customers. Net sales for the year ended September 30, 2003 decreased 9 percent from the year ended September 30, 2002. Our reduced sales reflected the continued slowdown in the technology markets served by Plexus, primarily in the network/datacommunications/ telecom, industrial/commercial and computer industries. Net sales in fiscal 2003 compared to net sales in fiscal 2002 were also adversely affected by the loss of the primary customer in our former San Diego facility. The slowdown in the technology markets in fiscal 2003 was offset, in part, by increased sales to the medical industry.one customer.
          The percentages of net sales to customers representing 10 percent or more of sales and net sales to our ten largest customers for the indicated periods were as follows:

          Sales to all of our largest customers may vary from time to time depending on the size and timing of program commencement, termination,commencements, terminations, delays, modifications and transitions. We remain dependent on continued sales to our significant customers, and weour customer concentration has increased during the year. We generally do not obtain firm, long-term purchase commitments from our customers. Customers'Customers’ forecasts can and do change as a result of their fluctuating end-market demand and other factors. Any material change in orders from these major accounts, or other customers, could materially affect our results of operations. For example, see Note 9 in Notes to Consolidated Financial Statements for matters which could affect our future sales to a significant customer in the United Kingdom. In addition, as our percentage of sales to customers in a specific industry becomes larger relative to other industries (as we are currently experiencing significant increases in the networking/datacommunications/telecomwireline/networking industry), we will become increasingly dependent upon economic and business conditions affecting that industry.

See Note 12 in Notes to Consolidated Financial Statements for certain financial information regarding our operating segments, including a detail of net sales by operating segment.
Gross profit.Gross profit and gross margins for the indicated periods were as follows (dollars in millions):
Fiscal years ended September 30, ----------------------------- 2004 2003 2002 ----------------------------- Gross Profit $ 86.8 $ 53.0 $ 81.3 Gross Margin 8.3% 6.6% 9.2%

  2005 2004 2003
Gross Profit $105.7  $86.8  $53.0 
Gross Margin  8.6%  8.3%  6.6%
          For the fiscal year ended October 1, 2005, gross profit improvements were primarily due to higher net sales and improved operating performances at several sites arising from lean manufacturing and other cost-reduction initiatives. Gross profit forand gross margin improvements were moderated, however, as a result of manufacturing inefficiencies and material control issues in our Juarez facility. Lower sales from traditionally higher-margin engineering services, and anticipated start-up costs related to a new facility in Penang also negatively impacted gross profit and gross margin in fiscal 2005.
          For the fiscal year ended September 30, 2004, increased $33.8 million from the fiscal year ended September 30, 2003, while gross margins increased to 8.3 percent from 6.6 percent over this same period. The improvement in gross profit and gross margin was primarily due to higher net sales and the benefits of the prior yearyear’s restructuring actions that resulted in enhanced manufacturing capacity utilization and better absorption of fixed manufacturing expenses.utilization. The primary prior yearfiscal 2003 restructuring actions benefiting fiscal 2004 gross margins includeincluded the closures of the San Diego and Richmond facility closures.facilities. The gross profit and gross margin improvements were somewhatpartially offset, however, by manufacturing inefficiencies related to the start of many new programs, higher compensation and benefits costs, including variable incentive compensation, and increased amortization of capitalized costs associated with an enterprise resource planning ("ERP")our common ERP platform. Gross profit for the fiscal year ended September 30, 2003 decreased $28.3 million from the fiscal year ended September 30, 2002, while gross margins decreased to 6.6 percent from 9.2 percent over this same period. The decline in gross profit and gross margin in fiscal 2003 from 2002 was due primarily to a slowdown in end-market demand, particularly in the networking/datacommunications/telecom and industrial/commercial industries, which resulted in reduced utilization of manufacturing capacity. Gross margins were also impacted by lower product pricing and higher costs incurred to transfer customer programs to other Plexus operating sites as a result of closing our San Diego and Richmond facilities.
          Gross margins reflect a number of factors that can vary from period to period, including product and service mix, the level of new facility start-up costs, inefficiencies attendant to the transition of new programs, product life cycles, sales volumes, price erosion within the electronics industry, overall capacity utilization, labor costs and efficiencies, the management of inventories, component pricing and shortages, the mix of turnkey and consignment business, fluctuations and timing of customer orders, changing demand for our customers'customers’ products and competition within the electronics industry. Additionally, turnkey manufacturing involves the risk of inventory management, and a change in component costs can directly impact average selling prices, gross margins and net sales. Although we focus on expanding gross margins, there can be no assurance that gross margins will not decrease in future periods.
          Most of the research and development we conduct is paid for by our customers and is therefore included in both sales and cost of sales. We conduct our own research and development, but that research and development is not specifically identified, and we believe such expenses are less than one percent of our sales. not material.

Operating expenses.Selling and administrative (S&A) expenses for the indicated periods were as follows (dollars in millions):
Fiscal years ended September 30, ----------------------------- 2004 2003 2002 ----------------------------- Selling and administrative expense $ 68.3 $ 65.2 $ 66.9 Percent of sales 6.6% 8.1% 7.6%
             
  Fiscal years ended
  October 1, September 30, September 30,
  2005 2004 2003
Selling and administrative expense $76.3  $68.3  $65.2 
Percent of sales  6.2%  6.6%  8.1%
          The dollar increase in S&A for the fiscal year ended October 1, 2005 was due to a combination of factors including increased spending for internal and external resources to comply with Section 404 of the Sarbanes-Oxley Act of 2002 (“Section 404”), an increase in bad debt expense, in part due to a small customer that encountered a liquidity issue during fiscal 2005, and the expense of additional personnel and other administrative expenses to support growth in Asia. These increases were offset in part by lower variable incentive compensation. The decrease in S&A as a percent of net sales was due primarily to the 18 percent increase in net sales in fiscal 2005 over the prior year.
          Through fiscal 2005, we accounted for stock option awards under the provisions of Accounting Principles Board No. 25, which resulted in no compensation expense in our consolidated results of operations. Effective in fiscal 2006, we will be required to adopt Statement of Financial Accounting Standards (“SFAS”) No 123(R), “Share-Based Payment: An Amendment of FASB Statements No. 123 and 95.” SFAS No 123(R) requires that we recognize stock-based compensation as an expense in our results of operations. The adoption of SFAS No. 123(R) is not expected to have a significant effect on our financial condition and will not affect consolidated cash flows; however, if stock options remain an important element of our long-term compensation for directors, officers and key employees, SFAS No. 123(R) is expected to have a significant adverse effect on our consolidated results of operations. Based on unvested options outstanding at October 1, 2005, the future compensation cost to be recognized as a result of the implementation of SFAS No. 123(R) is approximately $0.4 million, nearly all of which will be recognized in fiscal 2006.
          The dollar increase in S&A for the fiscal year ended September 30, 2004 increased $3.1 million from the fiscal year ended September 30, 2003was primarily due to variable incentive compensation expense and additional expenses for the support of information technology systems support related to the implementation of the newour common ERP platform, offset, in part, by $1.7 million of recoveries of accounts receivable that were either written off or reserved for in prior periods. In addition, we are currently undergoing a comprehensive effort to comply with Section 404 of the Sarbanes Oxley Act of 2002 ("Section 404"). During fiscal 2004, we devoted substantial internal resources in accounting, information technology and legal, supplemented by the use of external consultants, to the Section 404 compliance effort. We anticipate that we will continue to address our Section 404 compliance efforts in fiscal 2005 primarily through the use of internal resources. The significant decrease in S&A as a percent of net sales was due primarily to the highhigher level of net sales over the prior year.
Restructuring and impairment costs.The following table summarizes our restructuring and impairment costs for fiscal 2005, 2004, and 2003 (dollars in millions):
             
  Fiscal years ended 
  October 1,  September 30,  September 30,

Adjustments to asset impairments  0.4       
          
Total restructuring and impairment costs $39.2  $9.3  $59.3 
          
          The restructuring and impairment costs were associated with various segments. Such costs are not allocated to operating segments, as management excludes such costs when assessing the performance of the operating segments. See Note 12 S&A expensesin Notes to Consolidated Financial Statements for certain financial information regarding our operating segments, including a summary of restructuring and impairment costs by operating segment.
Fiscal 2005 restructuring and impairment costs:During fiscal 2005, we recorded pre-tax restructuring and impairment costs totaling $39.2 million. The restructuring and impairment costs were associated with goodwill impairment, the closure of the Bothell facility, the write-off of the remaining elements of a shop floor data-collection system, and other restructuring costs and adjustments to previously recognized restructuring and impairment actions.

15


Goodwill Impairment. We are required to perform goodwill impairment tests at a minimum on an annual basis, for which we selected the third quarter of each fiscal year, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. In the third quarter of fiscal 2005, we recorded goodwill impairment of $26.9 million, of which $16.1 million represented a partial impairment of goodwill associated with our operations in the United Kingdom (our European operating segment) and $10.8 million represented a full impairment of goodwill associated with our operations in Juarez (our Mexican operating segment). As of October 1, 2005, we have remaining goodwill of $7.0 million related to our operations in the United Kingdom.
          The impairment of goodwill associated with operations in the United Kingdom arose primarily from a significant medical customer’s recently expressed intention to transfer future production by the end of fiscal 2006 from the United Kingdom to a lower-cost location. The impairment also reflects lowered expectations for the United Kingdom’s electronics manufacturing services industry, in general. The impairment of goodwill associated with operations in Juarez reflects a lowered forecast of near-term profits and cash flows associated with recent operational issues and an anticipated transfer of a major customer’s program to another Plexus manufacturing facility.
          In July 2005, subsequent to our goodwill evaluation, our significant customer in the United Kingdom referred to above announced that it was under investigation by the Office of Communication (“OOC”), a government regulator in the United Kingdom, and would postpone the further installation of its product in the United Kingdom until the regulatory situation became clearer. In September 2005, the customer provided an updated announcement indicating that although the OOC’s investigation was still continuing, the investigation had appeared to diminish in scope, which the customer viewed as an encouraging step toward a positive resolution of the investigation. However, our future manufacturing for this customer remains uncertain.
Bothell Facility Closure. During fiscal year ended September 30, 2003 decreased2005, we incurred significant restructuring costs associated with the closure of the Bothell facility. We transferred key customer programs from the Bothell facility (a part of our United States operating segment) to other Plexus locations, primarily in the United States. This restructuring reduced our capacity by 97,000 square feet and affected approximately 160 employees. We completed the closure of the Bothell facility during fiscal 2005 (as previously announced in fiscal 2004). During fiscal 2005 and 2004, we incurred total restructuring and impairment costs associated with the Bothell facility closure of approximately $9.3 million, which consisted of the following elements:
$7.5 million was recorded in fiscal 2005 and consisted of $6.2 million for the facility lease, $1.1 million for employee retention costs and $0.2 million of other associated costs. The liability for the facility lease was recognized and measured at fair value for the future remaining lease payments subsequent to abandonment, less any estimated sublease income that could reasonably be obtained for the property;
$1.8 million was recorded in fiscal 2004 and consisted of $1.5 million for employee severance and $0.3 million for fixed asset impairments.
Shop Floor Data-Collection System Impairment.During fiscal 2005, we recorded a $3.8 million impairment of the remaining elements of a shop floor data-collection system. We had previously recorded a $1.7 million from the fiscal year ended September 30, 2002 primarily due to fiscal 2003 restructuring actions and reductions in corporate spending. These reductions were offset, in part, by approximately $1.2 million of additional expenses for information technology systems supportimpairment related to the implementationshop floor data-collection system in fiscal 2004 when it was determined that certain elements would not be utilized in any capacity. During the first quarter of fiscal 2005, we extended a maintenance and support agreement for the data-collection system through July 2005 to provide additional time to evaluate the remaining elements of the new ERP platform. Our ERP platform is intendedsystem. Based on our evaluation, we determined that the shop floor data-collection system was impaired. We abandoned deployment of these remaining elements of the shop floor data-collection system because the anticipated business benefits could not be realized. These costs were not allocated to augment our management information systems and includes various software systems to enhance and standardize our ability to globally translate information from production facilities into operational and financial information and create a consistent set of core business applications at our worldwide facilities.specific geographic operating segment.
Other Restructuring Costs. During fiscal 2004, one additional manufacturing facility was converted2005, we also recorded the following other restructuring and impairment costs:
$0.5 million, which consisted of $0.4 million associated with a workforce reduction and $0.1 million of asset impairments at the Juarez facility (our Mexican operating segment). The Juarez workforce reduction affected approximately 50 employees;
$0.3 million for severance associated with the elimination of a corporate executive position. These costs were not allocated to a specific geographic operating segment;

16


$0.2 million for a planned workforce reduction at a facility in Maldon, England (“Maldon”). As noted above, a significant customer in the United Kingdom intends to transfer future production from the United Kingdom to a lower-cost location by the end of fiscal 2006. As a result, we plan to consolidate the Maldon manufacturing operations into our facility in Kelso, Scotland and focus the Maldon facility on fulfillment and service and repair. This transition is anticipated to be completed by the end of fiscal 2006 and will result in a net workforce reduction of approximately 25 employees. During the transition period, we anticipate additional restructuring costs in the amount of $0.4 million to $0.6 million, most of which relates to employee retention costs;
$0.3 million of other restructuring costs. These costs were not allocated to a specific geographic operating segment.
Adjustments to the new ERP platform, which in additionProvisions: During fiscal 2005, we recorded certain adjustments to the two manufacturing facilities converted in 2003, results in approximately 50 percent of our net sales being managed on the new platform. We anticipate converting at least one more facilitypreviously recognized restructuring and impairment costs. All adjustments to the new ERP platform in fiscal 2005. Training and implementation costsprovisions are expected to continue over the next few quarters as we make system enhancements and convert an additional facility to the new ERP platform. The conversion timetable and project scope remain subject to change based upon our evolving needs and sales levels. In addition to S&A expenses associated with prior actions in the new ERP system, we continue to incur capital expenditures for hardware, softwareUnited States:
$0.4 million additional expense related to additional impairment of the closed facility in San Diego. During the first quarter of fiscal 2005, we subleased the remaining part of the San Diego facility, which resulted in the additional impairment to adjust the carrying value of the remaining part of the San Diego facility to its net present value of future sublease income;
a $0.4 million reduction in an accrual for lease exit costs associated with a warehouse located in Neenah. The Neenah warehouse was previously abandoned as part of a fiscal 2003 restructuring action; however, we reactivated use of the warehouse in the second quarter of fiscal 2005;
a $0.3 million reduction in an accrual for lease obligations for one of the closed facilities near Seattle. We subleased one of the two closed Seattle facilities held under operating leases.
          We currently expect that our fiscal 2005 restructuring actions will primarily benefit cost of sales through lower facilities costs and certain other costs for testing and installation. As of September 30, 2004, net property, plant and equipment includes $26.5 million related to the new ERP platform, including $3.9 million capitalized in fiscal 2004. We anticipate incurring at least an additional $6.0 million of capital expenditures for the ERP platform through fiscal 2005. employee expenses.
Fiscal 2004 restructuring and impairment actions:During fiscal 2004, we recorded pre-tax restructuring and impairment costs oftotaling $9.3 million. The restructuring and impairment costs were primarily associated with recognizingadjustments to previously recognized restructuring actions, specifically, additional lease obligations for two previously abandoned facilities near Seattle Washington (the "Seattle facilities"),facilities. In addition, we incurred restructuring and impairment costs associated with the planned closure of our Bothell engineering and manufacturing facility, the write-down of certain software components of our ERP platform and the consolidationclosure of a satellite PCB-design office in Hillsboro, Oregon into another Plexus design office.Oregon.
Adjustments to Provisions: The estimated cost for the closure of the Seattle facilities was included in our fiscal 2003 restructuring actions. The lease-related restructuring costs recorded in fiscal 2003 were based on future lease payments subsequent to abandonment, less estimated sublease income. As of September 30, 2004, the Seattle facilities had not been subleased. Based on the remaining term available to lease these facilities and the weaker than expected conditions in the local real estate market, we determined that we would most likely not be able to sublease the Seattle facilities. Accordingly, we recorded additional lease-related restructuring costs of $4.2 million in fiscal 2004. We also recorded $0.1 million of lease-related restructuring costs on a facility in Neenah, which had also been included in restructuring actions in fiscal 2003. As part ofThese adjustments were associated with our efforts to align our service offering with the evolving preferences of our customers, we are in the process of replicating the capabilities of our United States operating segment.
Bothell facility at other Plexus design and manufacturing locations that have higher productivity. We currently anticipate transferring key customer programs from the Bothell engineering and manufacturing facility to other Plexus locations primarily in the United States. This restructuring will reduce our manufacturing capacity by 97,000 square feet and affect approximately 160 employees. We currently expect the consolidation efforts will be completed by mid-fiscal 2005, subject to customer timelines.Facility Closure: In fiscal 2004, we incurred restructuring and impairment costs related to the Bothell closure of $1.8 million, which consisted of $1.5 million associated with employee terminations and $0.3 million associated with fixed asset impairments. In fiscal 2005, we anticipate the Bothell closure will result in additional restructuring costs of approximately $8.2 million, which will consist of $2.2 million associated with employee terminations and $6.0 million associated with the facility lease. Our fiscal 2004 restructuring actions, combined with other factors, also led to the establishment of a $36.8 million valuation allowance on our deferred income tax assets in fiscal 2004 (see discussion below).
Shop Floor Data-Collection System Impairment: We recorded a $1.7 million impairment of certain software components of our ERP platform, which primarily resulted from a change in our deployment strategy for a shop floor data-collection system. Someplatform. We determined that some elements of thea shop-floor data-collection system willwould not be deployed because the originally anticipated business benefits could not be realized. TheAlthough we continued to evaluate the remaining elements of the shop floor data-collection system are still under evaluation. As of September 30, 2004, the capitalized costs of the remaining elements of the shop floor data system totaled approximately $3.8 million. A change in the scope of this project could result ininto fiscal 2005, an impairment of the remaining elements of the shop floor data-collection system. Finally, wesystem was taken in fiscal 2005 after the evaluation was complete. These costs were not allocated to a specific geographic operating segment.

Closure of a PCB-Design Office: We incurred approximately $1.5 million of other restructuring and impairment costs in fiscal 2004 primarily related to the consolidation of the Hillsboro satellite PCB-design office into another Plexus design office. The Hillsboro related restructuring costs were primarily for employee termination costs and contract termination costs 13 associated with leased facilities and software service providers. In fiscal 2005, we anticipate incurring an additional $0.1 million of restructuring costs related to employee relocations. Approximately 40 employees were affected by this restructuring.
Fiscal 2003 restructuring and impairment actions:During fiscal 2003, we recorded pre-tax restructuring and impairment costs of $59.3 million. These costs resulted from actions taken in response to reductions in our end-market demand. Theserestructuring actions included closingthe closure of the San Diego and Richmond the consolidation of several leased facilities, re-focusing the PCB design group, a write-off of remaining goodwill associated with the acquisition of the San Diego facility, the write-down of underutilized assets to fair value at several locations, and the costs associated with reductions in work force in several manufacturing, engineering and corporate groups.various other actions. These measures were intended to align our capabilities and resources with lower industry demand.
San Diego Facility Closure: The Richmond facility was phased out of operation and sold in September 2003. Production was shifted to other Plexus operating sites in the United States and Mexico. The closure of Richmond resulted in a write-down of the building, a write-down of underutilized assets to fair value, and costs relating to the elimination of the facility's work force. Building impairment charges related to Richmond totaled $3.7 million. San Diego facility was closed in May 2003. The closure of the San Diego facility resulted in a write-off of remaining goodwill, the write-down of underutilized assets to fair value, and costs relating to the elimination of the facility'sfacility’s work force. Building impairment charges totaled $6.3 million. During fiscal 2003, goodwill impairment for San Diego totaled approximately $20.4 million, of which $14.8 million was impaired as a result of a transitional impairment evaluation under Statement of Financial Accounting Standards ("SFAS")SFAS No. 142 (see discussion below under "Cumulative“Cumulative effect of a change in accounting for goodwill"goodwill”) and $5.6 million was impaired as a result of our decision to close the facility.
Richmond Facility Closure: The Richmond facility was phased out of operation and sold in September 2003. Customer programs were shifted to other Plexus sites in the United States and Mexico. The closure of the Richmond facility resulted in a write-down of the building, a write-down of underutilized assets to fair value, and costs relating to severance for the facility’s work force. Building impairment charges related to Richmond totaled $3.7 million.
Other Restructuring and Impairment Costs: Other fiscal year 2003 restructuring and impairment actions included the consolidation of several leased facilities, the write-down of underutilized assets to fair value and work force reductions, which primarily affected operating sites in Juarez, Mexico ("Juarez"); Seattle; Neenah;Seattle, Neenah, and the United Kingdom ("UK").Kingdom. Restructuring actions also impacted our engineering and corporate organizations. Employee termination and severance costs for fiscal 2003 related to the termination ofwere for approximately 1,000 employees. Fiscal 2002 restructuring and impairment actions: During fiscal 2002, we recorded pre-tax restructuring and impairmentThese costs of $12.6 million. These charges resulted from actions taken in response to reductions in sales levels and capacity utilization and included the reduction of our work force and the write-off of certain underutilized assets to fair value at several locations. The employee termination and severance costs for fiscal 2002 affected approximately 700 employees. Thevarious operating site closures included two owned facilities: one located in Neenah (the oldest of our four facilities in Neenah) and the other located in Minneapolis, Minnesota. These facilities were no longer adequate to service the needs of our customers and would have required significant investment to upgrade. The Neenah facility was phased out of operation in February 2003 and is currently used for warehousing and administrative purposes. The Minneapolis facility was phased out of operation in July 2002 and sold in October 2002. There was no building impairment charge associated with the closure of these two facilities. The lease termination costs were primarily related to our facilities in Seattle and San Diego. The following table summarizes our restructuring and impairment costs for fiscal 2004, 2003 and 2002 (dollars in thousands):

14 segments.
          As of September 30, 2004,October 1, 2005, we have a remaining restructuring liability of approximately $11.8$12.0 million, of which $5.2$4.6 million is expected to be paid in fiscal 2005.2006. The remaining $6.6$7.4 million of accrued liabilities is expected to be paid through June 2008. We currently expect that our fiscal 2004 restructuring actions will result, when fully implemented, in annualized cost savings of approximately $2 million - $3 million. However, we currently expect that our operating performance will be impacted in our fiscal 2005 first and second quarters as we affect transfers from the Bothell facility to other locations. These savings will primarily benefit cost of sales through lower facilities and employee expenses. Fiscal 2002 merger and acquisition activity: For the year ended September 30, 2002, we also incurred approximately $0.3 million of acquisition costs related to the MCMS acquisition. October 2011.
Cumulative effect of a change in accounting for goodwill.We adopted SFAS No. 142 for the accounting for goodwill and other intangible assets as of October 1, 2002. Under the transitional provisions of SFAS No. 142, we identified locations with goodwill, performed impairment tests on the net goodwill and other intangible assets associated with each location using a valuation date as of October 1, 2002, and2002. We determined that a pre-tax transitional impairment charge of $28.2 million was required related to thefor goodwill associated with operations at San Diego and Juarez locations.Juarez. The impairment charge was recorded as a cumulative effect of a change in accounting for goodwill in our Consolidated Statements of Operations.
Income taxes.Income taxes for the indicated periods were as follows:

Effective annual tax rate  (12.9)%  515.0%  38.0%
          The reduction in fiscal 2005 income tax expense was primarily due to the inclusion of a $36.8 million valuation allowance in the prior year’s income tax expense (see further discussion below). Fiscal 2005 income tax expense of $1.4 million arose primarily from taxable income generated in the United Kingdom. Our expanding operations in Asia were profitable; however, those operations benefit from tax holidays which therefore resulted in no income tax expense for our Asian operations. Our U.S operations generated a pre-tax loss; however, a full valuation allowance against such losses eliminated any associated U.S. income tax benefit. As a result of the continued availability of deferred income tax assets, together with tax holidays in Asia, and if we are able to achieve our current profitability estimates, we anticipate that our effective tax rate for fiscal 2006 will be approximately 3 percent to 5 percent.

          The increase in fiscal 2004 income tax expense in fiscal 2004 was primarily due primarily to establishing a $36.8 million valuation allowance on all of our U.S. Federal and state deferred income tax assets. SFAS No. 109, "Accounting“Accounting for Income Taxes," requires that a valuation allowance be provided when it is more likely than not that the related income tax assets will not be utilized. Under SFAS No. 109, unless specific exceptions apply, historical operating results are a strong indicator of a company'scompany’s ability to generate future taxable income. In both fiscal 2003 and 2002, we hadAs a net loss. In fiscal 2004, although we achieved substantial sales growth and gross profit improvement, our fiscal 2004 restructuring actions resulted in only nominal operating income,result of the Company having a net loss in the U.S. for income tax purposes and anticipated additional restructuring charges that will be recorded in fiscal 2005. Consequently,2004, 2003 and 2002, we established a full valuation allowance on our U.S. deferred income tax assets in fiscal 2004. Although this valuation allowance reduces the carrying value of theour net deferred income tax assets, on the balance sheet, we may be able to utilize these deferred income tax assets in future profitable periods to reduce future tax obligations. As a result
          The effective income tax rate in fiscal 2005 decreased from fiscal 2004 due to the establishment of the continued availability of these deferredvaluation allowance in the prior year and the mix in tax jurisdictions in which income tax assets, together with tax holidays in Asia, and if we are able to achieve our current profitability estimates, our effective tax rate for fiscal 2005 would be approximately 5 percent to 8 percent.was earned. The effective income tax rate increased to 515 percent in fiscal 2004 compared to 38 percent infrom fiscal 2003 primarily due to the valuation allowance.
          In July 2005, a legislative body of the United Kingdom enacted the Finance Act (the “Finance Act”), which may limit the deduction of interest expense incurred in the United Kingdom when the corresponding interest income earned by the other party is not taxable to such party. We currently extend loans from a U.S. subsidiary to a United Kingdom subsidiary, which is affected by the Finance Act. The Finance Act is effective for interest expense incurred by the United Kingdom subsidiary on these loans arising or accrued after March 16, 2005. For the fiscal year ended October 1, 2005, we provided income tax rate increasedexpense for the full effect of the Finance Act on the non-deductibility of this interest expense based on our discussions to 38 percent in fiscal 2003 compared to 30 percent in fiscal 2002. The increasedate with the tax authorities in the effective tax rate was due primarily toUnited Kingdom regarding the absence in fiscal 2003application of non-deductible goodwill amortization expenses that were present in fiscal 2002. As of September 30, 2004 and 2003, we had recorded net deferred income tax assets of $1.7 million and $48.6 million, respectively. The net deferred income tax assets have arisen from available income tax losses and future income tax deductions. Our ability to use these income tax losses and future income tax deductions is dependent upon our future operations in the tax jurisdictions in which such losses or deductions arose. The decrease in deferred income tax assets in fiscal 2004 is due primarilyFinance Act to our recording of a $36.8 million valuation allowance as described above and the receipt of tax refunds. The deferred income tax assets that remain as of September 30, 2004 represent foreign deferred income tax assets for which realization is considered more likely than not.circumstances.
          In October 2004, the Working Families Tax Relief Act of 2004 and the American Jobs Creation Act of 2004 became(the “Jobs Act”) (see Note 1) was signed into law in the U.S. This legislation provides forUnited States. The Jobs Act includes a numberdeduction of changes in U.S. tax laws. In accordance with SFAS No. 109, effects85 percent of this new legislation will be reflected in our financial statements beginningcertain foreign earnings that are repatriated, as defined in the periodJobs Act. We may elect to apply this provision to qualifying earnings repatriations made in fiscal 2006. During fiscal 2005, we did not repatriate any qualified earnings pursuant to the Jobs Act. We have determined that $15.1 million to $26.4 million of existing foreign earnings will meet the requirements of the law's 15 enactment in October 2004.Jobs Act. We are presently reviewingevaluating the potential repatriation of earnings in the amounts ranging from $0 up to $15.1 million and currently estimate that a repatriation of earnings in this new legislationrange would result in income tax of up to determine the impacts on Plexus and our operations. approximately $0.8 million (or approximately 5 percent of any amounts repatriated).
LIQUIDITY AND CAPITAL RESOURCES
          Cash flows used inprovided by operating activities were ($21.4)$82.0 million for the year ended September 30, 2004,October 1, 2005, compared to cash flows used in operating activities of ($20.0)21.4) and cash flows provided by operating activities of $130.5($20.0) million for the years ended September 30, 20032004 and 2002,2003, respectively. During fiscal 2004,2005, cash used inprovided by operating activities was primarily drivenprovided by increased accounts payable and higher accrued liabilities and earnings (after adjusting for the non-cash effects of depreciation and amortization expense and non-cash asset impairments); these positive cash flow effects were offset, in part, by higher accounts receivable and inventory in support of higher sales, which were offset in part by higher earnings, after adjusting for the non-cash effect of depreciation and amortization, and the decrease in the deferred income tax assets, which primarily represented the establishment of a valuation allowance, and the receipt of tax refunds.sales.
          Our actual days sales outstanding in accounts receivable for the fiscal year ended September 30, 2004 increasedOctober 1, 2005 decreased to 5250 days in comparison to 50from 52 days for the prior year, primarily as a result of a higher percentage of fourth quarter net sales being recognized in the final month of fiscal 2004 as compared to the final month of fiscal 2003. During fiscal 2004, the allowance for losses on accounts receivable decreased $2.1 million, primarily as a result of a combination of collections and write-offs of accounts receivable that were reserved for in prior periods.stronger cash collections.
          Our inventory turns decreasedincreased to 6.4 turns for the year ended October 1, 2005 from 6.2 turns for the year ended September 30, 2004 from 6.5 turns for the year ended September 30, 2003.2004. Inventories increased $37.0$6.6 million from September 30, 2003,2004, primarily due to an increase in finished goods. Inventories increased as a result of certain new programs for the purchase of raw materials to support increased sales and the build up ofwhich we maintain finished goods in support of our customers’ needs. Although net sales increased 18 percent in fiscal 2005, raw material levels at October 1, 2005 were relatively flat in comparison to supportthe prior year end due to the establishment of certain new vendor managed inventory programs, all of which had a negative impact on inventory turns.programs.
          Cash flows used in investing activities totaled ($2.4)27.5) million for the year ended September 30, 2004.October 1, 2005. The primary uses wereinvestments included $21.7 million for purchases of property, plant and equipment offset by sales and maturities$6.0 million of net purchases of short-term investments.securities. Fiscal 2005 purchases of property, plant and equipment included $9.7 million, $10.4 million, $1.0 million and $0.6 million related to our U.S., Asian, United Kingdom and Mexican operations, respectively. Property, plant and equipment purchases within the U.S. included $1.2 million related to our common ERP platform. During fiscal 2005, we converted another manufacturing facility to the common ERP platform, and now manage a significant majority of our net sales on the common platform. As of October 1, 2005, net property, plant and equipment includes $22.3 million related to the new ERP platform.

          We utilized available cash a revolving credit facility and operating leases to fundcash flows as the principal sources for funding our operating requirements during fiscal 2004.2005. Our capital expenditures for fiscal 2004 were approximately $18.1 million. Ouractual level of capital expenditures for fiscal 20052006 will be dependentdepend on anticipated sales levels,demand, but we currently expect them to bespend in the range of $25$30 million to $30 million.$35 million, which includes approximately $16 million to $18 million for our Asian operations. We also plan to extend the common ERP platform to the remaining Plexus sites over the next two years; however, the conversion timetable for these remaining Plexus sites and project scope is subject to change based upon our evolving needs. Our anticipated fiscal 2006 capital expenditures include approximately $4 million to $5 million of capital expenditures for the common ERP platform.
          Cash flows provided by financing activities, totaling $4.2 million for the year ended September 30, 2004,October 1, 2005, primarily represent proceeds from the exercise of stock options and stock issuances under our Employee Stock Purchase Plan, and the exercise of stock options, offset by net payments on debt and capital lease obligations. We have suspended further employee stock purchases under the employee stock purchase plan as a result of SFAS No. 123(R), “Share-Based Payment an Amendment of FASB Statements No. 123 and 95.”
          Our secured revolving credit facility as(as amended, (the "Amended Securedthe “Secured Credit Facility"Facility”), allows us to borrow up to $150 million from a group of banks. Borrowing under the Amended Secured Credit Facility may be either through revolving or swing loans or letters of credit. The Amended Secured Credit Facility is secured by substantially all of our domestic working capital assets and a pledge of 65 percent of the stock of each of our foreign subsidiaries. Interest on borrowings varies with our total leverage ratio, as defined in our credit agreement, and begins at the Prime rate (as defined)defined in the agreement) or LIBOR plus 1.5 percent. We also are required to pay an annual commitment fee of 0.5 percent of the unused credit commitment. The Amended Secured Credit Facility matures on October 31, 2007 and includes certain financial covenants customary in agreements of this type. These covenants include a minimum adjusted EBITDA, a maximum total leverage ratio (not to exceed 2.5 times adjusted EBITDA)EBITDA for the trailing four quarters) and a minimum tangible net worth, all as defined in the agreement. The Secured Credit Facility includes a definition of adjusted EBITDA to exclude any impairment charges that may arise from time-to-time in our assessment of our goodwill. The exclusion of impairment charges from the adjusted EBITDA definition arose from a request made by us in connection with our annual evaluation of goodwill under SFAS No. 142, which occurs for Plexus in the third quarter of each fiscal year. For the third quarter of fiscal 2005, we identified $26.9 million of impairment losses related to our Juarez and United Kingdom operations (see “Fiscal 2005 Restructuring and Impairment Costs” above). We are allowed to repurchase common shares and pay cash dividends as long as we remain in compliance with the various covenants. We may not be able to arrange similar amendments in the future in order to accommodate changes or developments in our business or operations.
We believe that our Amendedprojected cash flows from operations, cash and short-term investments, the Secured Credit Facility and leasing capabilities and cash and short-term investments should be sufficient to meet our working capital and fixed capital requirements, as noted above, through fiscal 2005. However, the2006. Although our net sales growth anticipated for fiscal 2005 may2006 will increase our working capital needs.needs, we currently do not anticipate having to utilize our Secured Credit Facility to finance this growth. As thoseour financing needs increase, we may need to arrange additional debt or equity financing. We, therefore, evaluate and consider from time to time various financing alternatives to supplement our capital resources. However, we cannot be surecertain that we will be able to make any such arrangements on acceptable terms.
          We have not paid cash dividends in the past and do not anticipate paying them in the foreseeable future. We anticipate using any earnings to support the growth of our business. 16

DISCLOSURE ABOUT CRITICAL ACCOUNTING POLICIES
          Our accounting policies are disclosed in Note 1 to the Consolidated Financial Statements. During the year ended September 30, 2004,October 1, 2005, there were no material changes to these policies. Our more critical accounting policies are as follows: noted below:
Impairment of Long-Lived Assets - We review property, plant and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of property, plant and equipment is measured by comparing its carrying value to the projected cash flows that the property, plant and equipment are expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying value of the property exceeds its fair market value. The impairment analysis is based on significant assumptions of future results made by management, including salesrevenue and cash flow projections. Circumstances that may lead to impairment of property, plant and equipment include reductions in anticipatedreduced expectations for future performance of the asset, or industry demand and the restructuringpossible further restructurings. See Note 9 in Notes to Consolidated Financial Statements for discussion of our operations. additional asset impairments recorded in fiscal 2005.
Intangible Assets - We adopted SFAS No. 142, "Goodwill and Other Intangible Assets" effective October 1, 2002. Under SFAS No. 142, beginning“Goodwill and Other Intangible Assets,” which was effective October 1, 2002, we no longer amortize goodwill and intangible assets with indefinite useful lives, but instead we test those assets for impairment, at least annually, withand recognize any related losses recognized in earnings when incurred. We perform goodwill impairment tests annually during the third quarter of each fiscal year andor more frequently if an event or circumstance indicates that an impairment loss has occurred. See Note 9 in Notes to Consolidated Financial Statements for discussion of $26.9 million of goodwill impairment recorded in fiscal 2005.
          We measure the recoverability of goodwill under the annual impairment test by comparing a reporting unit'sunit’s carrying amount, including goodwill, to the reporting unit’s estimated fair market value, which is primarily estimated

21


using the present value of the reporting unit based on projected 17 discountedexpected future cash flows.flows, although market valuations may also be employed. If the carrying amount of the reporting unit exceeds its fair value, goodwill is considered impaired and a second test is performed to measure the amount of impairment. Circumstances that may lead to impairment of goodwill include, but are not limited to, the loss if any. of a significant customer or customers and unforeseen reductions in customer demand, future operating performance or industry demand.
Revenue - Net sales from manufacturing services isare generally recognized upon shipment of the manufactured product to our customers under contractual terms, which are generally FOB shipping point. Upon shipment, title transfers and the customer assumes risks and rewards of ownership of the product. Generally, there are no formal customer acceptance requirements or further obligations related to manufacturing services; if such requirements or obligations exist, then a sale is recognized at the time when such requirements are completed and such obligations fulfilled. Nets
          Net sales from engineering design and development services, which are generally performed under contracts of twelve months or less in duration, are recognized as costs are incurred utilizing thea percentage-of-completion method; any losses are recognized when anticipated. Net sales from engineering design and development services were less than ten percent of total sales for each of fiscal year 2004, 2003 and 2002.
          Sales are recorded net of estimated returns of manufactured product based on management'smanagement’s analysis of historical rates of returns, current economic trends and changes in customer demand. Net sales also include amounts billed to customers for shipping and handling.handling, if applicable. The corresponding shipping and handling costs are included in cost of sales.
Restructuring Costs - From fiscal 2002 through fiscal 2004,2005, we have taken a number of actions and recorded restructuring costs in response to reductions in sales andand/or reduced capacity utilization. These restructuring costs included employee severance and benefit costs, and costs related to plant closings, including leased facilities that will bewere abandoned (and subleased, as applicable). Prior to January 1, 2003, severance and benefit costs and lease exit costs were recorded in accordance with Emerging Issues Task Force ("EITF"(“EITF”) 94-3 and for leased facilities that were abandoned and subleased, the94-3. The estimated lease loss was accrued for future remaining lease payments subsequent to abandonment, less any estimated sublease income. As of September 30, 2004, theOctober 1, 2005, we have one significant facilities whichfacility in Seattle remaining to be subleased. If we planare able to sublease had not yet been subleased; and, accordingly, certainthe remaining Seattle facility, we would record a favorable adjustment to restructuring costs, as we did in fiscal 2005, when we recorded a $0.3 million favorable adjustment to restructuring costs as a result of our estimatesentering into a sublease for one of expected sublease income were changedthe Seattle facilities. See Note 9 in Notes to reflect factors that affect our ability to sublease those facilities such as general economic conditions and the local real estate markets. Changes in certainConsolidated Financial Statements for discussion of our estimates of sublease income resulted in additional restructuring costs recorded in fiscal 2004. Further changes in certain other estimates of sublease income could result in additional restructuring costs.2005.
          Subsequent to December 31, 2002, costs associated with a restructuring activity are recorded in compliance with SFAS No. 146, "Accounting“Accounting for Costs Associated with Exit or Disposal Activities." The timing and related recognition of recording severance and benefit costs that are not presumed to be an ongoing benefit, as defined in SFAS No. 146, dependsdepend on whether employees are required to render service until they are terminated in order to receive the termination benefits and, if so, whether employees will be retained to render service beyond a minimum retention period. During fiscal 2003, we concluded that we had a substantive severance plan based upon our past severance practices; therefore, we recorded certain severance and benefit costs in accordance with SFAS No. 112, "Employer's“Employer’s Accounting for Postemployment Benefits," which resulted in the recognition of a liability as the severance and benefit costs arose from an existing condition or situation and the payment was both probable and reasonably estimated.
          For leased facilities being abandoned and subleased, a liability is recognized and measured at fair value for the future remaining lease payments subsequent to abandonment, less any estimated sublease income that could reasonably be reasonably obtained for the property. For contract termination costs, including costs that will continue to be incurred under a contract for its remaining term without economic benefit to the entity, a liability for future remaining payments under the contract is recognized and measured at its fair value. See Note 109 in the Notes to Consolidated Financial Statements.Statements for discussion of a lease liability recorded in fiscal 2005 associated with the closure of our Bothell facility.
          The recognition of restructuring costs requires that we make certain judgments and estimates regarding the nature, timing and amount of costs associated with the planned exit activity. If our actual results in exiting these facilities differ from our estimates and assumptions, we may be required to revise the estimates of future liabilities, requiring thewhich would result in recording of additional restructuring costs or the reduction of liabilities already recorded. At the end of each reporting period, we evaluate the remaining accrued balances to ensure that no excess accruals are retained, no additional accruals are required and the utilization of the provisions are for their intended purpose in accordance with developed exit plans.

Income Taxes - Deferred income taxes are provided for differences between the bases of assets and liabilities for financial and income tax reporting purposes. The Company recordsWe record a valuation allowance against deferred income tax assets when management believes it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Realization of deferred income tax assets is dependent on our ability to generate sufficient future 18 taxable income. During fiscal 2004,Although we recorded a $36.8 million valuation allowance against all U.S. deferred income tax assets. See Note 5assets in fiscal 2004, we may be able to utilize these deferred income tax assets to offset future taxable income in the Notes to Consolidated Financial Statements. U.S.
NEW ACCOUNTING PRONOUNCEMENTS
          In November 2002,2004, the EITF reached a consensus regarding EITF Issue 00-21, "Accounting for Revenue Arrangements with Multiple Deliverables." The consensus addresses not only whenFinancial Accounting Standards Board (“FASB”) issued SFAS No. 151, “Inventory Costs, an amendment of ARB No. 43, Chapter 4” (“SFAS 151”), which requires that abnormal amounts of idle facility expense, freight, handling costs, and how an arrangement involving multiple deliverables shouldwasted material be divided into separate unitsrecognized as current period charges. In addition, this statement requires that allocation of accounting but also howfixed production overheads to the arrangement's consideration shouldcosts of conversion be allocated among separate units.

We will be required to adopt this statement in the first quarter of our fiscal 2004, but did2006. We do not anticipate that the implementation of this standard will have a material impact on our consolidatedfinancial position, results of operations or financial position.cash flows.
          In January 2003, theDecember 2004, FASB issued Interpretation No. 46, "ConsolidationStaff Position (“FSP”) FAS 109-2, “Accounting and Disclosure Guidance for the Foreign Earnings Repatriation Provision within the American Jobs Creation Act of Variable Interest Entities - an interpretation of ARB No. 51," which provides guidance on the identification of and reporting for variable interest entities.

          In May 2003,December 2004, the FASB issued SFAS No. 150, "Accounting for Certain Financial Instruments with Characteristics123(R), “Share-Based Payment: An Amendment of Both LiabilitiesFASB Statements No. 123 and Equity," which establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity.

Currently, we account for stock option awards under the provisions of APB No. 25, which to date has not resulted in compensation expense in our consolidated results of operations. We have selected a transition method in which prior period financial statements would not be restated. In addition, we will use the Black-Scholes valuation model, which is the same valuation model we use to value stock options for pro forma presentation of income and per-share data for SFAS No. 148 disclosure purposes (see Note 5 in Notes to Condensed Consolidated Financial Statements). The adoption of SFAS No. 123(R) is not expected to have a significant effect on our financial condition and will not affect consolidated cash flows; however, if stock options remain an important element revenue arrangements, supercededof long-term compensation for our officers and key employees, SFAS No. 123(R) is expected to have a significant adverse effect on our consolidated results of operations. Based on unvested options outstanding as of October 1, 2005, the future compensation expense to be recognized as a result of the issuance EITF 00-21, "Accountingimplementation of SFAS No. 123(R) is $0.4 million in fiscal 2006 and nominal amounts in each of fiscal 2007 and 2008 (Note 1 — New Accounting Pronouncements).
          In December 2004, the FASB issued SFAS No. 153, “Exchanges of Nonmonetary Assets — An Amendment of APB No. 29,” which eliminates the exception for Revenue Arrangementsnonmonetary exchanges of similar productive assets and replaces it with Multiple Deliverables." Additionally, SAB 104 rescinds the SEC's "Revenue Recognition in Financial Statements Frequently Asked Questions and Answers" document issued with SAB 101a general exception for exchanges of nonmonetary assets that had been codified in SEC Topic 13, Revenue Recognition. The adoption of this bulletin diddo not have an impactcommercial substance. Under SFAS 153, if a nonmonetary exchange of similar productive assets meets a commercial-substance criterion and the fair value is determinable, the transaction must be accounted for at fair value resulting in recognition of any gain or loss. We are required to adopt SFAS No. 153 for nonmonetary asset exchanges occurring in the first quarter of 2006 and our adoption is not expected to have a significant effect on our consolidated results of operations or financial position. condition.

          In March 2005, the FASB issued Interpretation No. 47, “Accounting for Conditional Asset Retirement Obligations” (“FIN 47”), which clarifies that an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value can be reasonably estimated even though uncertainty exists about the timing and/or method of settlement. We are required to adopt FIN 47 by the end of fiscal 2006. We are currently assessing the impact of FIN 47 on our results of operations and financial condition.
          In May 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections.” SFAS No. 154 replaces APB Opinion No. 20, “Accounting Changes,” and SFAS No. 3, “Reporting Accounting Changes in Interim Financial Statements,” and changes the requirements for the accounting for and reporting of a change in accounting principle. We are required to adopt SFAS No. 154 for accounting changes and error corrections in fiscal 2007. Our results of operations and financial condition will only be impacted by SFAS No. 154 if we implement changes in accounting principles that are addressed by the standard or have corrections of accounting errors.
          In June 2005, the FASB issued FSP No. FAS 143-1, “Accounting for Electronic Equipment Waste Obligations,” that provides guidance on how commercial users and producers of electronic equipment should recognize and measure asset retirement obligations associated with the European Directive 2002/96/EC on Waste Electrical and Electronic Equipment (“WEEE”). WEEE primarily impacts our operations in the United Kingdom. FSP No 143-1 is effective on the date that the United Kingdom adopts WEEE into law, which is anticipated sometime in fiscal 2006. We are currently assessing the impact of FSP No. 143-1 on our financial condition, results of operations and cash flows.
RISK FACTORS OUR CUSTOMER REQUIREMENTS AND OPERATING RESULTS VARY SIGNIFICANTLY FROM QUARTER TO QUARTER, WHICH COULD NEGATIVELY IMPACT THE PRICE OF OUR COMMON STOCK.
Our net sales and operating results may vary significantly from quarter to quarter, which could negatively impact the price of our common stock.
          Our quarterly and annual results and share price may vary significantly depending on various factors, many of which are beyond our control. These factors include: - the volume of customer orders relative to our capacity - the level and timing of customer orders, particularly in light of the fact that some of our customers release a significant percentage of their orders during the last few weeks of a quarter - the typical short life cycle of our customers' products - market acceptance of and demand for our customers' products - customer announcements of operating results and business conditions - changes in our sales mix to our customers - business conditions in our customers' industries - the timing of our expenditures in anticipation of future orders - our effectiveness in managing manufacturing processes - changes in cost and availability of labor and components - local events that may affect our production volume, such as local holidays - credit ratings and securities analysts' reports and - changes in economic conditions and world events. 19

A slowdown or flat performance in the U.S. or global economies,economy, or in particular in the industries served by us, may result in our customers reducing their forecasts. The demand for our services could weaken, or decrease, which in turn would impact our sales, capacity utilization, margins and financial results. Our sales were adversely affectedHistorically, we have seen periods, such as in fiscal 2003 and 2002, when our sales were adversely affected by thea slowdown in the networking/datacommunications/telecomwireline/networking and industrial/commercial markets,wireless infrastructure sectors, as a result of reduced end-market demand and reduced availability of venture capital to fund existing and emerging technologies.

When an increasing percentage of ourtotal net sales, is made to customers in a particular industry, we becomemaking us more dependent upon the performance of that industry and the economic and business conditions that affect it.
          Our quarterly and annual results are affected by the level and timing of customer orders, fluctuations in material costs and availabilities, and the degree of capacity utilization in the manufacturing process. THE MAJORITY OF OUR SALES COME FROM A RELATIVELY SMALL NUMBER OF CUSTOMERS AND IF WE LOSE ANY OF THESE CUSTOMERS, OUR SALES AND OPERATING RESULTS COULD DECLINE SIGNIFICANTLY.

24


The majority of our sales come from a relatively small number of customers, and if we lose any of these customers, our sales and operating results could decline significantly.
          Sales to our largest customer for the fiscal year ended October 1, 2005 represented 1419 percent of our net sales, while net sales to our largest customer in the fiscal 2004. A differentyear ended September 30, 2004 represented 14 percent of net sales. One other customer for the fiscal year ended October 1, 2005 represented 12 percent of our net sales insales. Sales to our largest customer for the fiscal 2003.year ended September 30, 2003 represented 12 percent of our net sales. We had no other customers that represented 10 percent or more of net sales in fiscal 2002.any of the periods. Sales to our ten largest customers have represented a majority, or near majority of our net sales in recent periods. Our ten largest customers accounted for approximately 60 percent, 51 percent 55 percent and 4855 percent of our net sales for the years ended October 1, 2005, September 30, 2004 2003 and 2002,September 30, 2003, respectively. Our principal customers have varied from year to year, and our principal customers may not continue to purchase services from us at current levels, if at all. Significant reductions in sales to any of these customers, or the loss of other major customers, could seriously harm our business. If we are not ablebusiness, such as the fiscal 2005 goodwill impairment associated with our operations in the United Kingdom that resulted from a significant customer’s announced intention to replace expired, canceledtransfer future production from our United Kingdom facility to a lower-cost location (see Note 9 in Notes Consolidated Financial Statements).
Our customers may cancel their orders, change production quantities or reduced contracts with new business on a timely basis, our sales will decrease. OUR CUSTOMERS MAY CANCEL THEIR ORDERS, CHANGE PRODUCTION QUANTITIES OR DELAY PRODUCTION. Electronics manufacturing service providersdelay production.
          EMS companies must provide rapid product turnaround for their customers. We generally do not obtain firm, long-term purchase commitments from our customers, and we continue to experience reduced lead-times in customer orders.customers. Customers may cancel their orders, change production quantities or delay production for a number of reasons that are beyond our control. The success of our customers'customers’ products in the market and the strength of the markets themselves affect our business. Cancellations, reductions or delays by a significant customer, or by a group of customers, could seriously harm our operating results. Such cancellations, reductions or delays have occurred and may continue to occur.
          In addition, we make significant decisions, including determining the levels of business that we will seek and accept, production schedules, component procurement commitments, facility requirements, personnel needs and other resource requirements, based on our estimates of customer requirements. The short-term nature of our customers'customers’ commitments and the possibility of rapid changes in demand for their products reduce our ability to accurately estimate the future requirements of those customers. Because many of our costs and operating expenses are relatively fixed, a reduction in customer demand can harm our gross margins and operating results.
          Customers may require rapid increases in production, which can stress our resources and reduce operating margins. Although we have had a net increase in our manufacturing capacity over the past few fiscal years, we have significantly reduced our capacity from its peak, and weWe may not have sufficient capacity at any given time to meet all of our customers'customers’ demands or to meet the requirements of a specific program. FAILURE TO MANAGE CONTRACTION AND GROWTH, IF ANY, MAY SERIOUSLY HARM OUR BUSINESS.
We invest in technology to support our operations; developments may impair those assets.
          We are involved in a multi-year project to install a common ERP platform and associated information systems at most of our manufacturing sites. Our ERP platform is intended to augment our management information systems and includes various software systems to enhance and standardize our ability to globally translate information from production facilities into operational and financial information and create a consistent set of core business applications at our worldwide facilities. As of October 1, 2005, facilities representing a significant majority of our net sales are currently managed on the common ERP platform. We plan to extend the common ERP platform to our remaining sites over the next two years; however, the conversion timetable and project scope for our remaining sites is subject to change based upon our evolving needs.
          During the year ended October 1, 2005, we recorded a $3.8 million impairment related to the remaining elements of a shop floor data-collection system. We partially impaired the shop floor data-collection system in the fourth quarter of fiscal 2004 when we determined that certain elements would not be utilized. During the first quarter of fiscal 2005, we extended a maintenance and support agreement for the data-collection system through July 2005 to provide additional time to evaluate the remaining elements of the system. Based on our evaluation, and as part of the preparation of our financial statements, we determined that the shop floor data-collection system was impaired. We determined that we would abandon deployment of these remaining elements of the shop-floor data-collection system because the anticipated business benefits could not be realized.
          As of October 1, 2005, overall ERP investments included in net property, plant and equipment totaled $22.3 million and we anticipate incurring up to an additional $4 million to $5 million of capital expenditures for the common

ERP platform in fiscal 2006. Changes in our technology needs may affect the utility of our common ERP platform and require additional expenditures in the future.
Failure to manage contraction and growth, if any, may seriously harm our business.
          Periods of contraction or reduced sales, such as the periods that occurred from fiscal 2001 through 2003, create tensions and challenges. We must determine whether all facilities remain productive, determine whether staffing levels need to be reduced, and determine how to respond to changing levels of customer demand. While maintaining multiple facilities or higher levels of employment increases short-term costs, reductions in employment could impair our ability to respond to later market improvements or to maintain customer relationships. Our decisions to reduce costs and capacity, such as the recent announcement to close thefiscal 2005 closure of our Bothell facility in fiscal 2005 and the fiscal year 2003 closures 20 of our San Diego and Richmond facilities and therelated reduction in the number of employees, can affect our expenses and, therefore, our short-term and long-term results. We have announced our intention
          Due to close our Bothell, Washington facilitycontinued growth in fiscal 2005. The exact timing of that closure will depend upon2005 and the arrangements for transitioning customer programs. Although we work to minimize the potential effects of any such transition, there are inherent risks that such a transition can result in the disruption of programs and customer relationships. We are involved in a multi-year project to install a common ERP platform and associated information systems. Our ERP platform is intended to augment our management information systems and includes various software systems to enhance and standardize our ability to globally translate information from production facilities into operational and financial information and create a consistent set of core business applications at our worldwide facilities. As of September 30, 2004, facilities generating approximately 50 percent of our net sales are being managed on the new platform. We anticipate converting at least one more facility to the new ERP platform in fiscal 2005. The conversion timetable and project scope remain subject to change based upon our evolving needs and sales levels. During fiscal 2004, we recorded a $1.7 million impairment of certain components of our ERP platform, which primarily resulted from a change in our deployment strategy for a shop floor data-collection system. Some elements of the shop-floor data-collection system will not be deployed because the originally anticipated business benefits could not be realized. The remaining elements of the shop floor data-collection system are still under evaluation. As of September 30, 2004, the capitalized costs of the remaining elements of the shop floor data system total approximately $3.8 million. A change in the scope of this project could result in impairment of the remaining elements of the shop floor data-collection system, As of September 30, 2004, overall ERP implementation costs included in net property, plant and equipment totaled $26.5 million and we anticipate incurring at least an additional $6.0 million in capital expenditures for the ERP platform through fiscal 2005; changes in the scope of the ERP platform could result in impairment of these capitalized costs. Due to recent rapid sales growth which occurred in fiscal 2004, we have experienced a significant need forneeded additional employees and facilities. We have added many employees aroundfacilities to meet incremental demand. In fiscal 2004, we began the world, and we are expandingexpansion of our operations in Penang, Malaysia. Our response to these changesMalaysia and added many employees, principally in business conditions in fiscal 2004, compared to the two previous fiscal years, hasAsia. These actions resulted in additional costs to support our growth. If we are unable to effectively manage thisthe growth and any future growth effectively,currently anticipated for fiscal 2006, our operating results could be harmed. OPERATING IN FOREIGN COUNTRIES EXPOSES US TO INCREASED RISKS.adversely affected.
          In addition, to meet our customers’ needs, or to achieve increased efficiencies, we sometimes require additional capacity in one location while reducing capacity in another. We are currently evaluating further expansion alternatives in Asia. Since customers’ needs and market conditions can vary and change rapidly, we may find ourselves in a situation where we simultaneously experience the effects of contraction in one location while incurring the costs of expansion in another location.
Operating in foreign countries exposes us to increased risks, including foreign currency risks.
          We have operations in China, Malaysia, Mexico and the United Kingdom. As noted above, we have expanded our operations in Malaysia, and we may in the future expand in these and/or into other international regions.locations. We have limited experience in managing geographically dispersed operations in these countries.operations. We also purchase a significant number of components manufactured in foreign countries. Because of theseThese international aspects of our operations we are subject us to the following risks that could materially impact our operating results: - economic or political instability - transportation delays or interruptions and other effects of less developed infrastructure in many countries - foreign exchange rate fluctuations - utilization of different systems and equipment - difficulties in staffing and managing foreign personnel and diverse cultures and -
economic or political instability
transportation delays or interruptions and other effects of the less-developed infrastructure in many countries
foreign exchange rate fluctuations
utilization of different systems and equipment
difficulties in staffing and managing foreign personnel in diverse cultures and
the effects of international political developments.
          In fiscal 2005, the Chinese and Malaysian governments revalued their currencies against the U.S. dollar. Both currencies had been relatively fixed to the U.S. dollar for the last several years, but both governments now appear to have adopted policies described as “managed floats” (that is, allowing their currencies to move in a tight range up or down from the previous day’s close). As our Asian operations expand, our failure to adequately hedge foreign currency transactions and/or currency exposures associated with assets and liabilities denominated in non-functional currencies could adversely affect our financial condition, results of operations and cash flows.
          In addition, changes in policies by the U.S. or foreign governments could negatively affect our operating results due to changes in duties, tariffs, taxes or limitations on currency or fund transfers. For example, our Mexican-based operation utilizesfacility in Mexico operates under the Mexican Maquiladora program, which provides for reduced tariffs and easeseased import regulations, andregulations; we could be adversely affected by changes in that program. Also, the Malaysian and Chinese subsidiaries currently receive favorable tax treatments from these governments which extend for approximately 29 years and 98 years, respectively, which may or may not be renewed. WE MAY NOT BE ABLE TO MAINTAIN OUR ENGINEERING, TECHNOLOGICAL AND MANUFACTURING PROCESS EXPERTISE.

26


We may not be able to maintain our engineering, technological and manufacturing process expertise.
          The markets for our manufacturing and engineering services are characterized by rapidly changing technology and evolving process development. The continued success of our business will depend upon our continued ability to: 21 - retain our qualified engineering and technical personnel - maintain and enhance our technological capabilities - develop and market manufacturing services which meet changing customer needs -
retain our qualified engineering and technical personnel
maintain and enhance our technological capabilities
develop and market manufacturing services which meet changing customer needs
successfully anticipate or respond to technological changes in manufacturing processes on a cost-effective and timely basis.
          Although we believe that our operations utilize the assembly and testing technologies, equipment and processes that are currently required by our customers, we cannot be certain that we will develop the capabilities required by our customers in the future. The emergence of new technology industry standards or customer requirements may render our equipment, inventory or processes obsolete or noncompetitive. In addition, we may have to acquire new assembly and testing technologies and equipment to remain competitive. The acquisition and implementation of new technologies and equipment may require significant expense or capital investment that could reduce our operating margins and our operating results. Our failure to anticipate and adapt to our customers'customers’ changing technological needs and requirements could have an adverse effect on our business. OUR MANUFACTURING SERVICES INVOLVE INVENTORY RISK.
Our manufacturing services involve inventory risk.
          Most of our contract manufacturing services are provided on a turnkey basis, whereunder which we purchase some, or all, of the required materials. These services involve greater resource investment and inventory risk than consignment services, where the customer provides these materials. Accordingly, various component price increases and inventory obsolescence could adversely affect our selling price, gross margins and operating results.
          In our turnkey operations, we need to order parts and supplies based on customer forecasts, which may be for a larger quantity of product than is included in the firm orders ultimately received from those customers. For example, fiscal 2004 saw a significant increase in inventories to support increased sales and expected growth in customer programs. Customers'Customers’ cancellation or reduction of orders can result in additional expense to us. While most of our customer agreements include provisions that require customers to reimburse us for excess inventory specifically ordered to meet their forecasts, we may not actually be reimbursed or be able to collect on these obligations. In that case, we could have excess inventory and/or cancellation or return charges from our suppliers.
          In addition, we provide a managed inventory programprograms for some of our key customers under which we hold and manage finished goods inventory for some of our key customers. Theinventories. These managed inventory programprograms may result in higher finished goods inventory levels, further reduce our inventory turns and increase our financial riskexposure with such customers, althoughcustomers. Even though our customers willgenerally have contractual obligations to purchase such inventories from us, we may remain subject to the inventory from us. WE MAY NOT BE ABLE TO OBTAIN RAW MATERIALS OR COMPONENTS FOR OUR ASSEMBLIES ON A TIMELY BASIS OR AT ALL.risk of enforcing those obligations.
We may not be able to obtain raw materials or components for our assemblies on a timely basis, or at all.
          We rely on a limited number of suppliers for many of the components used in the assembly process. We do not have any long-term supply agreements. At various times, there have been shortages of some of the electronic components that we use, and suppliers of some components have lacked sufficient capacity to meet the demand for these components. At times, component shortages have been prevalent in our industry, and in certain areassuch shortages may be expected to recur from time to time. In some cases, supply shortages and delays in deliveries of particular components have resulted in curtailed production, or delays indelayed production of assemblies, using that component, which contributed to an increase in our inventory levels. We expect that shortages and delays in deliveries of some components will continue from time to time, especially as demand for those components increases. An increase in economic activity could result in shortages, if manufacturers of components do not adequately anticipate the increased orders and/or have previously excessively cut back their production capability in view of reduced activity in recent years. World events, such as terrorism, armed conflict and epidemics, could also could affect supply chains. If we are unable to obtain sufficient components on a timely basis, we may experience manufacturing and shipping delays, which could harm our relationships with our customers and reduce our sales. A significant portion of our sales is derived from turnkey manufacturing in which we provide materials procurement.
          While most of our customer contracts permit quarterly or other periodic adjustments to pricing based on decreases and increaseschanges in component prices and other factors, we typically bear the risk of component price increases that occur between any such repricings or, if such repricing is not permitted, during the balance of the term of the particular customer contract. Accordingly, component price increases could adversely affect our operating results. 22 START-UP COSTS AND INEFFICIENCIES RELATED TO NEW OR TRANSFERRED PROGRAMS CAN ADVERSELY AFFECT OUR OPERATING RESULTS.

27


Start-up costs theand inefficiencies related to new or transferred programs can adversely affect our operating results.
          The management of labor and equipment resourcesproduction capacity in connection with the establishment of new programs and new customer relationships, and the need to estimate required resources in advance of production can adversely affect our gross margins and operating results.margins. These factors are particularly evident in the early stages of the life cycle of new products and new programs or program transfers. The effects of these start-up costs and inefficiencies can also occur when we open new facilities, such as our additionalnew facility in Penang, Malaysia, which began production in the first quarter of fiscal 2005. These factors also affect2005, or when we transfer programs, such as those made in connection with the fiscal 2005 closure of our ability to efficiently use labor and equipment. Due to the improved economy and ourBothell facility. Customer needs, capacity utilization rates and/or increased marketing efforts,demand may require that we expand certain facilities, or seek larger facilities in fiscal 2006, or future years. We are currently managing a number of new programs. Consequently, our exposure to these factors has increased. In addition, if any of these new programs or new customer relationships were terminated, our operating results could be harmed,worsen, particularly in the short term. WE ARE SUBJECT TO EXTENSIVE GOVERNMENT REGULATIONS.
          Although we try to minimize the potential losses of transitioning customer programs between Plexus facilities, there are inherent risks that such transitions can result in the disruption of programs and customer relationships.
We and our customers are subject to extensive government regulations.
          We are also subject to environmental regulations relating to the use, storage, discharge, recycling and disposal of hazardous chemicals used in our manufacturing process. If we fail to comply with present and future regulations, we could be subject to future liabilities or the suspension of business. These regulations could restrict our ability to expand our facilities or require us to acquire costly equipment or incur significant expense. While we are not currently aware of any material violations, we may have to spend funds to comply with present and future regulations or be required to perform site remediation. In addition, our
          Our medical device business, which represented approximately 3130 percent of our net sales in fiscal 2004,2005, is subject to substantial government regulation, primarily from the federal FDA and similar regulatory bodies in other countries. We must comply with statutes and regulations covering the design, development, testing, manufacturing and labeling of medical devices and the reporting of certain information regarding their safety. Failure to comply with these rulesregulations can result in, among other things, our and our customers being subject to fines, injunctions, civil penalties, criminal prosecution, recall or seizure of devices, or total or partial suspension of production. The FDA also has the authority to require repair or replacement of equipment, or refund of the cost of a device manufactured or distributed by our customers. Violations may lead to penalties or shutdowns of a program or a facility. In addition, failureFailure or noncompliance could have an adverse effect on our reputation.
          In addition, our customers’ failure to comply with applicable regulations or legal requirements, or even allegations of such failures, could affect our sales to those customers. For example, as discussed in Note 9 in Notes to Condensed Consolidated Financial Statements, a significant customer in the United Kingdom is under investigation by the Office of Communication, a government regulator in the United Kingdom. Even though our manufacturing services are not implicated in this investigation, it has delayed installations of the product and reduced our sales to that customer.
          In addition, there are two European Union (“EU”) directives which could affect our business and results. The first of these is the Restriction of the use of Certain Hazardous Substances (“RoHS”). RoHS becomes effective on July 1, 2006, and restricts within the EU the distribution of products containing certain substances, lead being the most relevant restricted substance to us. Although most of the EU member countries have not yet turned the mandates into legislation, it appears that we will be required to manufacture RoHS compliant products for customers intending to sell into the EU after the effective date. In addition, industry analysts indicate that similar legislation in the U.S. and Asia will eventually follow.
          The second EU directive is the Waste Electrical and Electronic Equipment directive, effective in August 2005, under which a manufacturer or importer will be required, at its own cost, to take back and recycle all of the products it either manufactured in or imported into the EU.
          Since both of these directives affect the worldwide electronics supply-chain, we expect to make collaborative efforts with our suppliers and customers to develop compliant processes and products. The cost of such efforts, the degree to which we will be expected to absorb such costs, the impact that the directive may have on product shipments, and our liability for non-compliant product is not yet known, but could have a material effect on our operations and results.

          In recent periods, our sales related to the defense industry, including homeland security,defense/security/aerospace sector have begun to increase. Companies that design and manufacture for this industrysector face governmental, security and other requirements that could materially affect their financial condition and results of operations. PRODUCTS WE MANUFACTURE MAY CONTAIN DESIGN OR MANUFACTURING DEFECTS THAT COULD RESULT IN REDUCED DEMAND FOR OUR SERVICES AND LIABILITY CLAIMS AGAINST US.
Products we manufacture may contain design or manufacturing defects that could result in reduced demand for our services and liability claims against us.
          We manufacture products to our customers'customers’ specifications that are highly complex and may at times contain design or manufacturing defects. Defects have been discovered in products we manufactured in the past and, despite our quality control and quality assurance efforts, defects may occur in the future. Defects in the products we manufacture, whether caused by a design, manufacturing or component defects,defect, may result in delayed shipments to customers or reduced or cancelled customer orders. If these defects occur in large quantities or too frequently, our business reputation may also be tarnished. In addition, these defects may result in liability claims against us. Even if customers are responsible for the defects, they may or may not be able to assume responsibility for any such costs or payments. OUR PRODUCTS ARE FOR THE ELECTRONICS INDUSTRY, WHICH PRODUCES TECHNOLOGICALLY ADVANCED PRODUCTS WITH SHORT LIFE CYCLES.required payments to us and we occasionally incur costs defending claims.
Our products are for the electronics industry, which produces technologically advanced products with relatively short life cycles.
          Factors affecting the electronics industry, in particular the short life cycle of products, could seriously harm our customers and, as a result, us. These factors include: -
the inability of our customers to adapt to rapidly changing technology and evolving industry standards that result in short product life cycles
the inability of our customers to develop and market their products, some of which are new and untested
the potential that our customers’ products may become obsolete or the failure of our customers’ products to gain widespread commercial acceptance.

          The end-markets for most of our customers in the networking/datacommunication/telecom industrywireline/networking and wireless infrastructure sectors are subject to regulation by the Federal Communications Commission, as well as by various state and foreign government agencies. The policies of these agencies can directly affect both the near-term and long-term consumer and provider demand and profitability of the industrysector and therefore directly impact the demand for products that we manufacture. INCREASED COMPETITION MAY RESULT IN DECREASED DEMAND OR PRICES FOR OUR SERVICES.
Increased competition may result in decreased demand or reduced prices for our services.
          The electronics manufacturing services industry is highly competitive and has become more so as a result of excess capacity in the industry. We compete against numerous U.S. and foreign electronics manufacturing services providers with global operations, as well as those whowhich operate on only a local or regional basis. In addition, current and prospective customers continually evaluate the merits of manufacturing products internally. Consolidations and other changes in the electronics manufacturing services industry result in a continually changing competitive landscape. The consolidation trend in the industry also results in larger and more geographically diverse competitors that may have significantly greater resources with which to compete against us.
          Some of our competitors have substantially greater managerial, manufacturing, engineering, technical, financial, systems, sales and marketing resources than we do. These competitors may: - respond more quickly to new or emerging technologies - have greater name recognition, critical mass and geographic and market presence - be better able to take advantage of acquisition opportunities - adapt more quickly to changes in customer requirements - devote greater resources to the development, promotion and sale of their services -

          We may be operating at a cost disadvantage compared to manufacturers who have greater direct buying power from component suppliers, distributors and raw material suppliers or who have lower cost structures. As a result,

competitors may have a competitive advantage and obtain business from our customers. Our manufacturing processes are generally not subject to significant proprietary protection, and companies with greater resources or a greater market presence may enter our market or increase their competition with us. Increased competition could result in price reductions, reduced sales and margins or loss of market share. WE DEPEND ON CERTAIN KEY PERSONNEL, AND THE LOSS OF KEY PERSONNEL MAY HARM OUR BUSINESS.

          Our success depends in large part on the continued service of our key technical and management personnel, and on our ability to attract and retain qualified employees, particularly those highly skilled design, process and test engineers involved in the development of new products and processes and the manufacture of existing products. The competition for these individuals is significant, and the loss of key employees could harm our business. WE MAY FAIL TO SUCCESSFULLY COMPLETE FUTURE ACQUISITIONS AND MAY NOT SUCCESSFULLY INTEGRATE ACQUIRED BUSINESSES, WHICH COULD ADVERSELY AFFECT OUR OPERATING RESULTS. Although we have previously grown through acquisitions,
Expansion of our current focus is on pursuing organic growth opportunities. If we were to pursue future growth through acquisitions, however, this would involve significant risks that could have a material adverse effect on us. These risks include: Operating risks, such as the: - inability to integrate successfullybusiness and operations may negatively impact our acquired operations' businesses and personnel - inability to realize anticipated synergies, economies of scale or other value - difficulties in scaling up production and coordinating management of operations at new sites - strain placed on our personnel, systems and resources - possible modification or termination of an acquired business's customer programs, including cancellation of current or anticipated programs and - loss of key employees of acquired businesses. 24 Financial risks, such as the: - use of cash resources, or incurrence of additional debt and related interest expenses - dilutive effect of the issuance of additional equity securities - inability to achieve expected operating margins to offset the increased fixed costs associated with acquisitions, and/or inability to increase margins at acquired entities to Plexus' desired levels - incurrence of large write-offs or write-downs - impairment of goodwill and other intangible assets - unforeseen liabilities of the acquired businesses. EXPANSION OF OUR BUSINESS AND OPERATIONS MAY NEGATIVELY IMPACT OUR BUSINESS.business.
          We have expanded our presence in Malaysia and may further expand our operations by establishing or acquiring other facilities or by expanding capacity in our current facilities. We may expand both in geographical areas in which we currently operate and in new geographical areas within the United States and internationally. We may not be able to find suitable facilities on a timely basis or on terms satisfactory to us. Expansion of our business and operations involves numerous business risks, including: -
the inability to successfully integrate additional facilities or capacity and to realize anticipated synergies, economies of scale or other value
additional fixed costs which may not be fully absorbed by the new business
difficulties in the timing of expansions, including delays in the implementation of construction and manufacturing plans
creation of excess capacity, and the need to reduce capacity elsewhere if anticipated sales or opportunities do not materialize
diversion of management’s attention from other business areas during the planning and implementation of expansions
strain placed on our operational, financial, management, technical and information systems and resources
disruption in manufacturing operations
incurrence of significant costs and expenses
inability to locate sufficient customers or employees to support the expansion.
Our operations could be negatively affected by an epidemic.
          We have a production facility in Xiamen, China, which is one of the countries that have been most at risk in the current outbreak of avian flu. We also operate in Malaysia, which is in the area in which avian flu has spread. To the best of our knowledge, concerns about the spread of avian flu have not affected our employees or operations in China or Malaysia, nor have we experienced any disruption in our supply chain as a result of these concerns. However, our production in Asia could be severely impacted by an epidemic spread of avian flu or a similar widespread disease or epidemic. Our facilities could be closed by government authorities, some or all of our workforce could be unavailable due to quarantine, fear of contagion or other factors, and transportation or other elements of the infrastructure could be affected, leading to delays or loss of production.
          Concerns relating to avian flu are currently limited to Asia; however, avian flu or other outbreaks of disease or epidemics could similarly affect our other facilities. These health-related factors could also affect our suppliers and lead to a shortage of components. They could also lead to a reduction in end-customer demand.
We may fail to successfully integrate additional facilities or capacitycomplete future acquisitions and to realize anticipated synergies, economies of scale or other value - additional fixed costs which may not be fully absorbed by the new business - difficulties in the timing of expansions, including delays in the implementation of construction and manufacturing plans - creation of excess capacity, and the needsuccessfully integrate acquired businesses, which could adversely affect our operating results.
          Although we have previously grown through acquisitions, our current focus is on pursuing organic growth opportunities. If we were to reduce capacity elsewhere if anticipated salespursue future growth through acquisitions, however, this would involve significant risks that could have a material adverse effect on us. These risks include:

          Operating risks, such as the:
inability to integrate successfully our acquired operations’ businesses and personnel
inability to realize anticipated synergies, economies of scale or other value
difficulties in scaling up production and coordinating management of operations at new sites
strain placed on our personnel, systems and resources
possible modification or termination of an acquired business’s customer programs, including cancellation of current or anticipated programs

WE MAY FAIL TO SECURE NECESSARY FINANCING.maintain necessary financing.
          We maintain an Amendeda Secured Credit Facility with a group of banks, which allows us to borrow up to $150 million.million depending upon compliance with related covenants and conditions. However, we cannot be sure that the Amended Secured Credit Facility will provide all of the financing capacity that we will need in the future.future or that we will be able to amend the Secured Credit Facility or revise covenants, if necessary or appropriate in the future, to accommodate changes or developments in our business and operations.
          Our future success may depend on our ability to obtain additional financing and capital to support increased sales and our possible future growth. We may seek to raise capital by: - issuing additional common stock or other equity securities - issuing debt securities - modifying existing credit facilities or obtaining new credit facilities -
issuing additional common stock or other equity securities
issuing debt securities
modifying existing credit facilities or obtaining new credit facilities
a combination of these methods.
          We may not be able to obtain capital when we want or need it, and capital may not be available on satisfactory terms. If we issue additional equity securities or convertible debt to raise capital, it may be dilutive to shareholders'shareholders’ ownership interests. Furthermore, any additional financing may have terms and conditions that adversely affect our business, such as restrictive financial or operating covenants, and our ability to meet any financing covenants will largely depend on our financial performance, which in turn will be subject to general economic conditions and financial, business and other factors. RECENTLY ENACTED CHANGES IN THE SECURITIES LAWS AND REGULATIONS ARE LIKELY TO INCREASE COSTS.
Recently enacted changes in the securities laws and regulations have increased our costs.
          The Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act"“Sarbanes-Oxley Act”) that became law in July 2002 has required changes in some of our corporate governance, securities disclosure and compliance practices. In response to the requirements of the Sarbanes-Oxley Act, the SEC and the NASDAQ Stock Market have promulgated new rules inon a 25 variety of subjects. Compliance with these new rules has increased our legal and accounting costs, and we expect these increased costs to continue indefinitely. These developments may also make it more difficult for us to attract and retain qualified members of our board of directors or qualified executive officers. IF WE RECEIVE OTHER THAN AN UNQUALIFIED OPINION ON THE ADEQUACY OF OUR INTERNAL CONTROL OVER FINANCIAL REPORTING AS OF SEPTEMBER 30,Compliance with these new rules has increased our legal and accounting costs, most significantly in fiscal 2005, AND FUTURE YEAR-ENDS AS REQUIRED BY THE SECTIONwhich was our first year of compliance. We expect our compliance costs to continue; however, absent significant changes in related rules (which we cannot assure), we anticipate these costs may be lower in future years as we become more efficient in our compliance processes.

If we reach other than an affirmative conclusion on the adequacy of our internal control over financial reporting as required by the Section 404 OF THE SARBANES-OXLEY ACT, INVESTORS COULD LOSE CONFIDENCE IN THE RELIABILITY OF OUR FINANCIAL STATEMENTS, WHICH COULD RESULT IN A DECREASE IN THE VALUE OF THE OUR COMMON STOCK.of the Sarbanes-Oxley Act, investors could lose confidence in the reliability of our financial statements, which could result in a decrease in the value of our common stock.
          As required by Section 404 of the Sarbanes-Oxley Act, the SEC adopted rules requiring public companies to include a report of management on the company'scompany’s internal control over financial reporting in their annual reports on Form 10-K10-K; that containsreport must contain an assessment by management of the effectiveness of the company'scompany’s internal control over financial reporting. In addition, the public accounting firm auditing a company'scompany’s financial statements must attest to and report on both management'smanagement’s assessment as to whether the company maintained effective internal control over financial reporting and on the effectiveness of the company'scompany’s internal control over financial reporting. We are currently undergoing
          In fiscal 2006, we will continue a comprehensive effort to comply with Section 404 of the Sarbanes-Oxley Act. If we are unable to complete our assessment in a timely manner or if we and/or our independent auditors issue other than an unqualified opinion ondetermine that there are material weaknesses regarding the design or operating effectiveness or management's assessment of our internal control over financial reporting, this could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements, which could cause the market price of our shares to decline. A weakness in Plexus' stock
The price could mean that investors will not be able to sell their shares at or above the prices that they paid. A weakness in stock price could also impair Plexus' ability in the future to offerof our common stock or convertible securities as a source of additional capital and/or as consideration in the acquisition of other businesses. THE PRICE OF OUR COMMON STOCK HAS BEEN AND MAY CONTINUE TO BE VOLATILE.has been and may continue to be volatile.
          Our stock price has fluctuated significantly in recent periods. The price of our common stock may fluctuate significantly in response to a number of events and factors relating to us, our competitors and the market for our services, many of which are beyond our control.
          In addition, the stock market in general, and especially the NASDAQ Stock Market, along with share prices for technology companies in particular, have experienced extreme volatility, including weakness, that sometimes has been unrelated to the operating performance of these companies. These broad market and industry fluctuations may adversely affect the market price of our common stock, regardless of our operating results. Our stock price and the stock price of many other technology companies remain below their peaks.
          Among other things, volatility and weakness in Plexus'Plexus’ stock price could mean that investors willmay not be able to sell their shares at or above the prices that they paid. Volatility and weakness could also impair Plexus'Plexus’ ability in the future to offer common stock or convertible securities as a source of additional capital and/or as consideration in the acquisition of other businesses.
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
          We are exposed to market risk from changes in foreign exchange and interest rates. To reduce such risks, weWe selectively use financial instruments. FOREIGN CURRENCY RISKinstruments to reduce such risks.
Foreign Currency Risk
          We do not use derivative financial instruments for speculative purposes. Our policy is to selectively hedge our foreign currency denominated transactions in a manner that substantially offsets the effects of changes in foreign currency exchange rates. Presently, we use foreign currency contracts to hedge only those currency exposures associated with certain assets and liabilities denominated in non-functional currencies. Corresponding gains and losses on the underlying transaction generally offset the gains and losses on these foreign currency hedges. Our international operations create potential foreign exchange risk. As of September 30, 2004,October 1, 2005, we had no foreign currency contracts outstanding. 26
          Our percentages of transactions denominated in currencies other than the U.S. dollar for the indicated periods were as follows:
Fiscal year ------------------------------ 2004 2003 2002 ------------------------------ Net Sales 10% 8% 9% Total Costs 14% 11% 11%
INTEREST RATE RISK
             
  Fiscal year
  2005 2004 2003
Net Sales  9%  10%  8%
Total Costs  13%  14%  11%

Interest Rate Risk
          We have financial instruments, including cash equivalents and short-term investments, which are sensitive to changes in interest rates. We consider the use of interest-rate swaps based on existing market conditions. We currently do not use any interest-rate swaps or other types of derivative financial instruments to hedge interest rate risk.
          The primary objective of our investment activities is to preserve principal, while maximizing yields without significantly increasing market risk. To achieve this, we maintain our portfolio of cash equivalents and short-term investments in a variety of highly rated securities, money market funds and certificates of deposit and limit the amount of principal exposure to any one issuer.
          Our only material interest rate risk is associated with our secured credit facility. A 10 percent change in our weighted average interest rate on our average long-term borrowings would have had only a nominal impact on net interest expense in fiscal 2005, 2004 2003 and 2002. 2003.

ITEM 9A. CONTROLS AND PROCEDURES
Disclosure Controls and Procedures:The Company maintains disclosure controls and procedures designed to ensure that the information the Company must disclose in its filings with the Securities and Exchange Commission (“SEC”) is recorded, processed, summarized and reported on awithin the time periods specified in the SEC’s rules and forms, and such information is accumulated and communicated to management, as appropriate to allow timely basis.decisions regarding required disclosure. The Company'sCompany’s principal executive officer and principal financial officer have reviewed and evaluated, with the participation of the Company'sCompany’s management, the Company'sCompany’s disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"“Exchange Act”) as of the end of the period covered by this report (the "Evaluation Date"“Evaluation Date”). Based on such evaluation, such officers have concluded that, as of the Evaluation Date, the Company'sCompany’s disclosure controls and procedures are effective in bringing to their attentioneffective.
Management’s Report on a timely basis material information relating to the Company required to be included in the Company's periodic filings under the Exchange Act. Internal Control Over Financial Reporting: As previously disclosed,Management of the Company commenced a phased implementation of a global Enterprise Resource Planning (ERP) platform in fiscal 2001. Through September 30, 2004, four facilities have been converted to the ERP platform, including one facility converted in fiscal 2004. The conversion of the facility in fiscal 2004is responsible for establishing and the related changes to the Company'smaintaining adequate internal control (asover financial reporting, as such term is defined in Exchange Act RulesRule 13a-15(f). Management of the Company, including its chief executive officer and 15(d)-15(f)) did not have a material effect on, nor is it reasonably likely to materially affect,chief financial officer, has assessed the Company'seffectiveness of its internal control over financial reporting. reporting as of October 1, 2005, based on the criteria established in “Internal Control — Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on its assessment and those criteria, management of the Company has concluded that, as of October 1, 2005, the Company’s internal control over financial reporting was effective.
          Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of the effectiveness to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.
          PricewaterhouseCoopers LLP, independent registered public accounting firm, has audited management’s assessment of the Company’s internal control over financial reporting as of October 1, 2005, as stated in their report included herein on page 37.
Changes in Internal Control Over Financial Reporting:There have been no other changes in the Company'sCompany’s internal control over financial reporting that occurred during the Company'sCompany’s most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company'sCompany’s internal control over financial reporting. The Company is currently undergoing a comprehensive effort to comply with Section 404 of the Sarbanes-Oxley Act of 2002. Compliance is required for our fiscal year-end September 30, 2005. This effort includes documenting and testing of internal controls.

          During the course of these activities,the Company’s assessment of its internal control over financial reporting, the Company has identified certain internal control issues which management believes should be improved. The Company's review continues, but to date the Company has not identified any material weaknesses in its internal control as defined by the Public Company Accounting Oversight Board. The Company is nonetheless making improvements to its internal controls over financial 27 reporting as a result of its review efforts.efforts; however, management does not believe these improvements represent a significant change that would be likely to materially affect the Company’s internal control over financial reporting. These planned improvements include additional information technology system controls, further formalization of policies and procedures, improved segregation of duties and additional monitoring controls.
          The matters noted herein have been discussed with the Company'sCompany’s Audit Committee. The Company believes that it is taking the necessary steps to monitor and maintain appropriate internal control during periods of change.

29 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

36


Report of Independent Registered Public Accounting Firm
To the Shareholders and
Board of Directors
of Plexus Corp.:
We have completed an integrated audit of Plexus Corp.’s 2005 consolidated financial statements and of its internal control over financial reporting as of October 1, 2005 and audits of its 2004 and 2003 consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits, are presented below.
Consolidated financial statements and financial statement schedules
In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of Plexus Corp. and its subsidiaries at September 30, 2004October 1, 2005 and September 30, 2003,2004, and the results of their operations and their cash flows for each of the three years in the period ended September 30, 2004October 1, 2005 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedules listed in the accompanying indexpresent fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. These financial statements and financial statement schedules are the responsibility of the Company'sCompany’s management. Our responsibility is to express an opinion on these financial statements and financial statement schedules based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit of financial statements includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
As discussed in Note 1, the Company adopted Statement of Financial Accounting Standards No. 142, "Goodwill“Goodwill and Other Intangible Assets," effective October 1, 2002.
Internal control over financial reporting
Also, in our opinion, management’s assessment, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A, that the Company maintained effective internal control over financial reporting as of October 1, 2005 based on criteria established inInternal Control — Integrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of October 1, 2005, based on criteria established inInternal Control — Integrated Frameworkissued by the COSO. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on management’s assessment and on the effectiveness of the Company’s internal control over financial reporting based on our audit. We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the

37


transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Consolidation Principles: Principles and Basis of Presentation:The consolidated financial statements have been prepared in accordance with generally accepted accounting principles and include the accounts of Plexus Corp. and its subsidiaries.Plexus. All significant intercompany transactions have been eliminated.
     Effective October 1, 2004, the Company’s fiscal year now ends on the Saturday closest to September 30 rather than on September 30, as was the case prior to fiscal 2005. In connection with the change to a fiscal year ending on the Saturday nearest September 30, the Company also changed the accounting for its interim periods to adopt a “4-4-5” weeks accounting system for the interim periods in each quarter. Each quarter, therefore, ends on a Saturday at the end of the 4-4-5 week period. The accounting periods for fiscal 2005 and 2004 each included 366 days.
Cash Equivalents and Short-Term Investments:Cash equivalents are highly liquid investments purchased with an original maturity of less than three months. Short-term investments include investment-grade short-term debt instruments with original maturities greater than three months. Short-term investments are generally comprised of securities with contractual maturities greater than one year but with optional or early redemption provisions or rate reset provisions within one year.
     Investments in debt securities are classified as "available-for-sale."“available-for-sale.” Such investments are recorded at fair value as determined from quoted market prices, and the cost of securities sold is determined on the specific identification method. If material, unrealized gains or losses are reported as a component of comprehensive income or loss, net of the related income tax effect. For fiscal 2005, 2004 2003 and 2002,2003, unrealized or realized gains and losses were not material.
     As of October 1, 2005 and September 30, 2004, and 2003, cash and cash equivalents included the following securities (in thousands):
2004 2003 ---- ---- Money market funds and other $15,797 $22,757 U.S. corporate and bank debt 16,297 28,877 State and municipal securities - 4,000 ------- ------- $32,094 $55,634 ======= =======

judgment. Customers may cancel their orders, change production quantities or delay production for a number of reasons that are beyond the Company'sCompany’s control. Any of these, or certain additional actions, could impact the valuation of inventory. Any actions taken by the Company'sCompany’s customers that could impact the value of its inventory are considered when determining the lower of cost or market valuations.
Property, Plant and Equipment and Depreciation:These assets are stated at cost. Depreciation, determined on the straight-line method, is based on lives assigned to the major classes of depreciable assets as follows: 35 PLEXUS CORP. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED
Buildings and improvements 15-50 years 15-50years
Machinery and equipment 3-10 years 3-10years
Computer hardware and software 3-10 years 3-10years
     Certain facilities and equipment held under capital leases are classified as property, plant and equipment and amortized using the straight-line method over the lease terms and the related obligations are recorded as liabilities. Lease amortization is included in depreciation expense (see Note 3) and the financing component of the lease payments is classified as interest expense.
     For the capitalization of software costs, the Company follows Statement of Position ("SOP"(“SOP”) 98-1, "Accounting“Accounting for the Costs of Computer Software Developed for Internal Use." The Company capitalizes significant costs incurred in the acquisition or development of software for internal use, including the costs of the software, consultants and payroll and payroll related costs for employees directly involved in developing internal use computer software once the final selection of the software is made (see Note 3). Costs incurred prior to the final selection of software and costs not qualifying for capitalization are expensed as incurred.
Goodwill and Other Intangible Assets:Assets: The Company adopted Statement of Financial Accounting Standards ("SFAS"(“SFAS”) No. 142, "Goodwill“Goodwill and Other Intangible Assets"Assets” effective October 1, 2002. Under SFAS No. 142, beginning October 1, 2002, the Company no longer amortizes goodwill and intangible assets with indefinite useful lives, but instead, the Company tests those assets for impairment at least annually, withand recognizes any related loss recognized in earningslosses when incurred. Recoverability of goodwill is measured at the reporting unit level. The Company'sUpon the adoption of SFAS No. 142, the Company’s goodwill was assigned to three reporting units: San Diego, California ("(“San Diego"Diego”), Juarez, Mexico ("Juarez"(“Juarez”) and Kelso, Scotland and Maldon, England ("(“United Kingdom"Kingdom”). As of September 30, 2004, only the Juarez and United Kingdom reporting units had goodwill remaining. SFAS No. 142 requiredOctober 1, 2005, the Company to perform a transitionalhad remaining goodwill impairment evaluation that required the Company to perform an assessment of whether there was an indication$7.0 million, all of goodwill impairment as of the date of adoption. The Company completed the evaluation and concluded that it had goodwill impairmentswhich related to San Diego and Juarez, since the estimated fair value based on expected future discounted cash flows to be generated from each reporting unit was significantly less than their respective carrying value. The Company then compared the respective carrying amounts of San Diego's and Juarez's goodwill to the implied fair value of each reporting unit's respective goodwill. The implied fair value was determined by allocating the fair value to each respective reporting unit's assets and liabilities in a manner similar to a purchase price allocation for an acquired business. Both values were measured at the date of adoption. The Company identified $28.2 million of transitional impairment losses ($23.5 million, net of income tax benefits) related to San Diego and Juarez, which were recognized as a cumulative effect of a change in accounting for goodwilloperations in the Consolidated Statements of Operations.United Kingdom.
     The Company is required to perform goodwill impairment tests at least on an annual basis, for which the Company selected the third quarter of each fiscal year, andor whenever events or changes in circumstances indicate that the carrying value may not be recoverable from estimated future cash flows. Inrecoverable. Since the first quarterCompany’s adoption of fiscal 2003,SFAS No. 142 and excluding the transitional goodwill impairment noted below, the Company has recorded aggregate goodwill impairment of $32.5 million, which includes $26.9 million, $0 and $5.6 million of goodwill was impaired as a result of the Company's decision to close the San Diego facility (see Note 10). The Company'srecorded in fiscal year2005, 2004 and 2003, annual impairment tests did not result in any further impairment. However, norespectively (see Note 9). No assurances can be given that future impairment tests of goodwill will not result in further goodwill impairment or that changes in circumstances will not arise which result in further goodwill impairment.
     We measure the recoverability of goodwill under the annual impairment test by comparing the reporting unit’s carrying amount, including goodwill, to the reporting unit’s estimated fair market value, which is primarily estimated using the present value of expected future cash flows, although market valuations may also be employed. If the carrying amount of the reporting unit exceeds its fair value, goodwill is considered impaired and a second test is performed to measure the amount of impairment. Circumstances that may lead to impairment of goodwill include, but are not limited to, the loss of a significant customer or customers and unforeseen reductions in customer demand, future operating performance or industry demand.
     As of the adoption date of SFAS No. 142, the Company was required to perform a transitional goodwill impairment evaluation. The Company concluded that it had goodwill impairment related to its San Diego and Juarez operations, since the estimated fair value based on expected future discounted cash flows to be generated from each operation was significantly less than their respective carrying value. The Company then compared the respective carrying amounts of goodwill for the San Diego and Juarez operations to the

implied fair value of each operation’s respective goodwill. The implied fair value was determined by allocating the fair value to each respective operation’s assets and liabilities in a manner similar to a purchase price allocation for an impairment. The following sets forth a reconciliationacquired business. Both values were measured at the date of net income (loss) and earnings per share information foradoption.

     The Company has a nominal amount of identifiable intangibles that are subject to amortization. These intangibles relate to patents with useful lives of twelve years. The Company has no intangibles, except goodwill, that are not subject to amortization. During fiscal 2004,2005, there were no additions to intangible assets. Intangible asset amortization expense was nominal for fiscal 2005, 2004 2003 and 2002. 2003.
Impairment of Long-Lived Assets: The Company adopted SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" effective October 1, 2002. SFAS No. 144 modifies and expands the financial accounting and reporting for the impairment or disposal of long-lived assets other than goodwill, which is specifically addressed in SFAS No. 142. SFAS No. 144 maintains the requirement that an impairment loss be recognized for a long-lived asset to be held and used if its carrying value is not recoverable from its undiscounted cash flows, with the recognized impairment being the difference between the carrying amount and fair value of the asset. With respect to long-lived assets to be disposed of other than by sale, SFAS No. 144 requires that the asset be considered held and used until it is actually disposed of, but requires that its depreciable life be revised in accordance with APB Opinion No. 20 "Accounting Changes." Impairment charges recorded in fiscal 2003 against the carrying value of certain of the Company's long-lived assets are discussed in Note 10. The Company reviews property, plant and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of property, plant and equipment is measured by comparing its carrying value to the projected cash flows the property, plant and equipment are expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying value of the property exceeds its fair market value. The impairment analysis is based on significant assumptions of future results made by management, including sales and cash flow projections. Circumstances that may lead to impairment of property, plant and equipment include decreases inreduced expectations for future performance or industry demand and the restructuring of the Company's operations. possible further restructurings.
Revenue Recognition:Net sales from manufacturing services are generally recognized upon shipment of the manufactured product to the Company'sCompany’s customers under contractual terms, which are generally FOB shipping point. Upon shipment, title transfers and the customer assumes risks and rewards of ownership of the product. Generally, there are no formal customer acceptance requirements or further obligations related to manufacturing services; if such requirements or obligations exist, then a sale is recognized at the time when such requirements are completed and such obligations are fulfilled.
     Net sales from engineering design and development services, which are generally performed under contracts of twelve months or less duration, are recognized as costs are incurred utilizing thea percentage-of-completion method; any losses are recognized when anticipated. Progress towards completion of product design and development contracts is based on units of work for labor content and costs incurred for component content. Net sales from engineering design and development services were less than ten percent of total sales in fiscal 2005, 2004 2003 and 2002.2003.
     Sales are recorded net of estimated returns of manufactured product based on management'smanagement’s analysis of historical returns, current economic trends and changes in customer demand. Net sales also include amounts billed to customers for shipping and handling. The corresponding shipping and handling costs are included in cost of sales.

Restructuring Costs:From time to time, the Company has recorded restructuring costs in response to the reduction in its sales levels and reduced capacity utilization. These restructuring charges included employee severance and benefit costs, costs related to plant closings, including leased facilities that will be abandoned (and subleased, as applicable), and impairment of equipment. Prior to January 1, 2003, severance and benefit costs were recorded in accordance with Emerging Issues Task Force ("EITF"(“EITF”) 94-3. For leased facilities that were abandoned and subleased, the estimated lease loss wasCompany accrued for future remaining lease payments subsequent to abandonment, less any estimated sublease income. As of September 30, 2004,October 1, 2005, certain of the significantCompany’s facilities which the Companyit plans to sublease have not yet been subleased and, accordingly, the Company'sCompany’s estimates of expected sublease income could change based on factors that affect its ability to sublease those facilities such as general economic conditions and the real estate market, among others. 38 PLEXUS CORP. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED
     Subsequent to December 31, 2002, costs associated with a restructuring activity are recorded in accordance with SFAS No. 146, "Accounting“Accounting for Costs Associated with Exit or Disposal Activities." The timing and related recognition of recording severance and benefit costs that are not presumed to be an ongoing benefit, as defined in SFAS No. 146, dependsdepend on whether employees are required to render service until they are terminated in order to receive the termination benefits and, if so, whether employees will be retained to render service beyond a minimum retention period. The Company concluded that it had a substantive severance plan based upon past severance practices; therefore, certain severance and benefit costs were recorded in accordance with SFAS No. 112, "Employer's“Employer’s Accounting for Postemployment Benefits," which resulted in the recognition of a liability as the severance and benefit costs arose from an existing condition or situation and the payment was both probable and reasonably estimated.
     For leased facilities that will be abandoned and subleased, a liability is recognized and measured at fair value for the future remaining lease payments subsequent to abandonment, less any estimated sublease income that could be reasonably obtained for the property, is recognized and measured at its fair value.property. For contract termination costs, including costs that will continue to be incurred under a contract for its remaining term without economic benefit to the entity,Company, a liability for future remaining payments under the contract is recognized and measured at its fair value.
     The recognition of restructuring costs requires that the Company make certain judgments and estimates regarding the nature, timing and amount of cost associated with the planned exit activity. If actual results in exiting these facilities differ from the Company'sCompany’s estimates and assumptions, the Company may be required to revise the estimates of future liabilities, requiring thewhich could result in recording of additional restructuring costs or the reduction of liabilities already recorded. At the end of each reporting period, the Company evaluates the remaining accrued balances to ensure that no excess accruals are retained, no additional accruals are required, and the utilization of the provisions are for their intended purpose in accordance with developed exit plans.
Income Taxes:Deferred income taxes are provided for differences between the bases of assets and liabilities for financial and income tax reporting purposes. The Company records a valuation allowance against deferred income tax assets when management believes it is more likely than not that some portion or all of the deferred income tax assets will not be realized (see Note 5). Realization of deferred income tax assets is dependent on ourthe Company’s ability to generate future taxable income.
Foreign Currency:For foreign subsidiaries using the local currency as their functional currency, assets and liabilities are translated at exchange rates in effect at year-end, with net sales, expenses and cash flows translated at the monthly exchange rates. Adjustments resulting from translation of the financial statements are recorded as a component of accumulated other comprehensive income. Exchange gains and losses arising from transactions denominated in a currency other than the functional currency of the entity involved and remeasurement adjustments for foreign operations where the U.S. dollar is the functional currency are included in the statement of operations. Exchange gains and losses(losses) on foreign currency transactions were not significant$(0.5) million, $0.5 million and $0.3 million for the years ended October 1, 2005 and September 30, 2004 and 2003, and 2002, respectively. Derivatives:
Derivatives: The Company periodically enters into derivative contracts, primarily foreign currency forward, call and put contracts which are designated as cash-flow hedges. The changes in fair value of these

Notes to Consolidated Financial Statements — Continued
contracts, to the extent the hedges are effective, are recognized in other comprehensive income until the hedged item is recognized in earnings. These amounts were not material during fiscal 2005, 2004 2003 and 2002. 2003.
Earnings Per Share:The computation of basic earnings per common share is based upon the weighted average number of common shares outstanding and net income (loss). The computation of diluted earnings per common share reflects additional dilution from stock options, unless such shares are antidilutive.
Stock-based Compensation: In December 2002, SFAS No. 148, "Accounting for Stock-Based Compensation -- Transition and Disclosure -- an amendment of SFAS No. 123" was issued. SFAS No. 148 provides alternative methods of transition for an entity that voluntarily changes to the fair-value-based method of accounting for stock-based employee compensation and is effective for fiscal years ending after December 15, 2002. In addition, SFAS No. 148 requires prominent disclosures in both annual and interim financial statements about the effects on reported net income of an entity's method of accounting for stock-based employee compensation. The disclosure provisions were effective for the Company in the second 39 PLEXUS CORP. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED quarter of fiscal 2003. The Company did not effect a voluntary change in accounting to the fair value method, and, accordingly, the adoption of SFAS No. 148 did not have a significant impact on the Company's results of operations or financial position. The Company accounts for its stock option plans under the guidelines of Accounting Principles Board Opinion No. 25, "Accounting“Accounting for Stock Issued to Employees." Accordingly, no compensation expense related to the stock option plans has been recognized in the Consolidated Statements of Operations.Operations and Comprehensive Income (Loss). The Company'sCompany’s stock-based employee compensation plans are more fully described in Note 11.10. In December 2004, the Financial Accounting Standards Board (“FASB”) published SFAS No. 123 (R), “Share-Based Payment: An Amendment of FASB Statements No. 123 and 95.” SFAS 123R, which is effective from the first annual period that begins after June 15, 2005, will require that compensation cost related to share-based payment transactions, including stock options, be recognized in the financial statements. Accordingly, the Company will implement the revised standard in the first quarter of fiscal year 2006 (see “New Accounting Pronouncements” section below for further discussion).
     On May 11, 2005, in response to SFAS No. 123 (R), the Compensation/Leadership Development Committee of the Company’s Board of Directors (the “Compensation Committee”) approved the acceleration of the vesting of approximately 660,000 shares of unvested stock options outstanding under the Company’s stock option plan with exercise prices per share of $12.20 or higher. The accelerated options have a range of exercise prices of $12.25 to $27.37 and a weighted average exercise price of $15.17. The effective date of the acceleration was May 11, 2005. The primary purpose of the accelerated vesting was to avoid recognizing compensation expense associated with these options upon adoption of SFAS No. 123(R). The aggregate pre-tax expense associated with the accelerated options would have been approximately $5.0 million, of which $2.8 million and $1.0 million would have been reflected in the Company’s consolidated statements of operations in fiscal years 2006 and 2007, respectively.
     On May 18, 2005, the Compensation Committee granted approximately 700,000 stock options to key officers and employees of the Company. In response to SFAS No. 123 (R), and as allowed under the Company’s 2005 Equity Incentive Plan, the Compensation Committee provided that these options would vest immediately. The primary purpose of the immediate vesting was to avoid recognizing compensation expense associated with these options upon adoption of SFAS No. 123(R). The aggregate pre-tax expense associated with the immediate vesting of these options would have been approximately $3.9 million, of which $1.3 million, $1.3 million and $0.8 million would have been reflected in the Company’s consolidated statements of operations in fiscal years 2006, 2007 and 2008, respectively.
     The Company utilizes the Black-Scholes option valuation model to value stock options for pro forma presentation of income and per-share data as if the fair value-based method in SFAS No. 148, “Accounting for Stock-Based Compensation-Transition and Disclosure-an amendment of SFAS No. 123,” had been used to account for stock-based compensation.

New Accounting Pronouncements: In November 2002, the EITF reached a consensus regarding EITF Issue 00-21, "Accounting for Revenue Arrangements with Multiple Deliverables." The consensus addresses not only when and how an arrangement involving multiple deliverables should be divided into separate units of accounting, but also how the arrangement's consideration should be allocated among separate units. The pronouncement was effective for the Company commencing with its first quarter of fiscal year 2004 but did2006. The Company does not anticipate that the implementation of this standard will have a material impact on its financial position, results of operations or cash flows.
     In December 2004, the FASB issued Staff Position (“FSP”) FAS 109-2, “Accounting and Disclosure Guidance for the Foreign Earnings Repatriation Provision within the American Jobs Creation Act of 2004,” (the “Jobs Act”). The Jobs Act became law in the U.S. in October 2004. This legislation provides for a number of changes in U.S. tax laws. FSP SFAS No. 109-2 requires recognition of a deferred tax liability for the tax effect of the excess of book over tax basis of an investment in a foreign corporate venture that is permanent in duration, unless a company firmly asserts that such amounts are indefinitely reinvested outside the company’s home jurisdiction. However, due to the lack of clarification of certain provisions within the Jobs Act, FSP SFAS No. 109-2 provides companies additional time beyond the financial reporting period of enactment to evaluate the effect of the Jobs Act on its plan for reinvestment or repatriation of foreign earnings for purposes of applying SFAS No. 109. Management is presently reviewing this new legislation, in conjunction with income tax legislation enacted in July 2005 in the United Kingdom (see Note 12), to determine the impact on the Company’s consolidated results of operations and financial position.
     In December 2004, the FASB issued SFAS No. 123(R), which requires measurement of the cost of employee services received in exchange for an award of equity instruments based on the fair value of the award at the grant date (with limited exceptions) and recognition of the compensation expense over the period during which an employee is required to provide service in exchange for the award. In March 2005, the U.S. Securities and Exchange Commission (“SEC”) issued Staff Accounting Bulletin No. 107 (“SAB 107”), which expresses views of the SEC staff regarding the application of SFAS No. 123(R). Among other things, SAB

Notes to Consolidated Financial Statements — Continued
107 provides interpretive guidance related to the interaction between SFAS No. 123(R) and certain SEC rules and regulations, as well as provides the SEC staff’s views regarding the valuation of share-based payment arrangements for public companies. The Company is required to adopt SFAS No. 123(R) in its first quarter of fiscal 2006. Currently, the Company accounts for its stock option awards under the provisions of APB No. 25, which to date has not resulted in compensation expense in the Company’s consolidated results of operations. Management has selected a transition method in which prior period financial statements would not be restated. In addition, management will use the Black-Scholes valuation model, which is the same valuation model the Company uses to value stock options for proforma presentation of income and per-share data for SFAS No. 148 disclosure purposes. The adoption of SFAS No. 123(R) is not expected to have a significant effect on the Company’s financial condition and will not affect consolidated cash flows; however, if stock options remain an important element of the Company’s long-term compensation for its officers and key employees, SFAS No. 123(R) is expected to have a significant adverse effect on the Company’s consolidated results of operations.
     Based on unvested options outstanding at October 1, 2005, the future compensation cost to be recognized as a result of the implementation of SFAS No. 123(R) is as follows (in thousands of dollars):

     In December 2004, the FASB issued SFAS No. 153, “Exchanges of Nonmonetary Assets — An Amendment of APB No. 29,” which eliminates the exception for nonmonetary exchanges of similar productive assets and replaces it with a general exception for exchanges of nonmonetary assets that do not have commercial substance. Under SFAS 153, if a nonmonetary exchange of similar productive assets meets a commercial-substance criterion and the fair value is determinable, the transaction must be accounted for at fair value resulting in recognition of any gain or loss. The Company is required to adopt SFAS No. 153 for nonmonetary asset exchanges occurring in the first quarter of 2006 and its adoption is not expected to have a significant effect on the Company’s results of operations or financial position.condition.

Notes to Consolidated Financial Statements — Continued
Use of Estimates:The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Fair Value of Financial Instruments:Accounts payable and accrued liabilities are reflected in the consolidated financial statements at cost because of the short-term duration of these instruments. Accounts receivables are reflected at net realizable value based on anticipated losses due to potentially uncollectible balances. Anticipated losses are based on management'smanagement’s analysis of historical losses and changes in customer credit status. The fair value of capital lease obligations is approximately $25.4$24.5 million and $26.0$25.4 million as of October 1, 2005 and September 30, 2004, and 2003, respectively. The Company uses quoted market prices when available or discounted cash flows to calculate these fair values.
Business and Credit Concentrations:Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash, cash equivalents, short-term investments and trade accounts receivable. The Company'sCompany’s cash, cash equivalents and short-term investments are managed by recognized financial institutions that follow the Company'sCompany’s investment policy. Such investment policy limits the amount of credit exposure in any one issue and the maturity date of the investment securities that typically comprise investment grade short-term debt instruments. Concentrations of credit risk in accounts receivable resulting from sales to major customers are discussed in Note 13.12. The Company, at times, requires advanced cash deposits for services performed. The Company also closely monitors extensions of credit. Related Party Transactions: The Company holds a minority equity interest in MemoryLink Corp. ("MemoryLink"). The minority equity interest represents less than a ten percent ownership interest in MemoryLink and is accounted for under the cost method. The Company had nominal sales to MemoryLink during fiscal 2004 and 2003 and no sales in fiscal 2002. The Company received the minority equity interest in fiscal 2002, as settlement for accounts receivable that had been previously written off. Due to uncertainty regarding MemoryLink's financial viability, the Company recorded the minority equity interest at a zero value.

     The Company entered intois a party to a secured three-year revolving credit facility (the "Secured(as amended, the “Secured Credit Facility"Facility”) with a group of banks that allows the Company to borrow up to $100$150 million. The Secured Credit Facility expires on October 31, 2007. Borrowings under the Secured Credit Facility may be either through revolving or swing loans or letter of credit obligations. As of October 1, 2005, we had no borrowings outstanding. The Secured Credit Facility is secured by substantially all of the Company'sCompany’s domestic working capital assets and a pledge of 65 percent of the stock of the Company'sCompany’s foreign subsidiaries. The Secured Credit Facility contains certain financial covenants, which include certain minimum adjusted EBITDA amounts, maximum outstanding borrowings (not to exceed 2.5 times the adjusted EBITDA for the trailing four quarters) and a minimum tangible net worth, all as defined in the amended agreement. Interest on borrowings varies with usagedepending upon the Company’s then-current total leverage ratio and begins at the Prime rate, as defined, or LIBOR plus 1.5 percent. The Company is also required to pay an annual commitment fee of 0.5 percent of the unused credit commitment. The Secured Credit Facility contains certain financial covenants, which include a maximum total leverage ratio, a $40.0 million minimum balance of domestic cash or marketable securities, a minimum tangible net worth and a minimum adjusted EBITDA, as defined in the agreement. The Company amended the Secured Credit Facility in October 2003, and in April, July, August and November 2004, to revise certain terms and covenants (the "Amended Secured Credit Facility"). The most significant amendments occurred in July 2004, and included an increase in the maximum borrowing amount to $150 million from $100 million, an approximate one-year extension of the maturity of the Amended Secured Credit Facility to October 31, 2007, elimination of the requirement to maintain a $40 million minimum balance of domestic cash or marketable securities, modification of a minimum adjusted EBITDA and a maximum total leverage ratio (not to exceed 2.5 times adjusted EBITDA), all as defined in the amended agreement. In addition, the interest rate on borrowings will vary depending upon the Company's then-current total leverage ratio; before amendment, the rate varied with usage. Origination fees and expenses totaled approximately $1.2 million, which$1.4 million. The origination fees and expenses have been deferred and are being amortized to interest expense over the term of the Amended Secured Credit Facility. Effective December 26, 2002,Interest expense related to the commitment fee, amortization of deferred origination fees and borrowings totaled approximately $1.2 million, $1.2 million and $0 in fiscal 2005, 2004 and 2003, respectively.
     On June 30, 2005, the Company amended the Secured Credit Facility to revise a financial covenant. The amendment revised the definition of adjusted EBITDA to exclude any impairment charges that may arise from time-to-time in the Company’s assessment of its goodwill. The amendment was requested by the Company in connection with its annual evaluation of goodwill under SFAS No. 142 (see Note 1), which occurs for Plexus in the third quarter of each fiscal year. For the third quarter of fiscal 2005, the Company identified $26.9 million of goodwill impairment losses related to its Juarez and United Kingdom operations (see Note 9).
     In fiscal 2003, the Company terminated its prior credit facility ("(“Old Credit Facility"Facility”). No amounts were outstanding during the first quarter of fiscal 2003 prior to the termination of the Old Credit Facility.

8. ACQUISITIONS AND MERGERS Acquisitions: In January 2002, the Company acquired certain assets of MCMS, Inc. ("MCMS"), an electronics manufacturing services provider, for approximately $42 million in cash. The assets purchased from MCMS include manufacturing operations in Penang, Malaysia; Xiamen, China; and Nampa, Idaho. The Company acquired these assets primarily to provide electronic manufacturing services in Asia and increase its customer base. The Company recorded the acquisition utilizing the accounting principles promulgated by SFAS No.'s 141 and 142. The consideration for this acquisition did not include the assumption of any interest-bearing debt but included the assumption of total liabilities of approximately $7.2 million. The Company allocated the purchase price primarily to accounts receivable, inventory and property, plant and equipment, based on a number of factors, including a third-party valuation. The results from MCMS' operations are reflected in the Company's financial statements from the date of acquisition. No goodwill resulted from this acquisition. The Company incurred approximately $0.3 million of acquisition costs during fiscal 2002 associated with the acquisition of the MCMS operations. Due to unique aspects of this acquisition, pro forma financial information is not meaningful and is therefore not presented. The factors leading to this determination included the selective MCMS assets acquired by the Company, the limited assumption of liabilities and the exclusion of certain customer relationships which were formerly significant to MCMS. 9. OPERATING LEASE COMMITMENTSOperating Lease Commitments
     The Company has a number of operating lease agreements primarily involving manufacturing facilities, manufacturing equipment and computerized design equipment. These leases are non-cancelable and expire on various dates through 2016. Rent expense under all operating leases for fiscal 2005, 2004 2003 and 20022003 was approximately $11.0 million, $11.2 million $14.1 million and $14.6$14.1 million, respectively. Renewal and purchase options are available on certain of these leases. Rental income from subleases amounted to $1.7 million, $1.5 million $1.3 million and $1.0$1.3 million in fiscal 2005, 2004 and 2003, and 2002, respectively.
     Future minimum annual payments on operating leases are as follows (in thousands):
2005 $14,754 2006 12,731 2007 10,697 2008 7,972 2009 7,318 Thereafter 24,601 ------- $78,073 =======

Thereafter  16,602 
    
  $58,558 
    
     For certain leased facilities that were abandoned as result of restructuring actions (see Note 10)9), the Company accrued estimated losses for future remaining lease payments subsequent to abandonment, less any estimated sublease income. The above table of future minimum annual payments on operating leases includes future payments totaling $9.5$11.5 million that are reflected as an obligation for lease exit costs as of September 30, 2004October 1, 2005 in the accompanying Consolidated Balance Sheets. 10. RESTRUCTURING AND IMPAIRMENT COSTS
9. Restructuring and Impairment Costs
Fiscal 2005 restructuring and impairment costs:During fiscal 2005, the Company recorded pre-tax restructuring and impairment costs totaling $39.2 million. The restructuring and impairment costs were associated with goodwill impairment, the closure of our Bothell facility, the write-off of the remaining elements of a shop floor data-collection system and other restructuring costs and adjustments to previously recognized restructuring actions.
Goodwill Impairment. The Company is required to perform goodwill impairment tests at least on an annual basis, for which it selected the third quarter of each fiscal year, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. In the third quarter of fiscal 2005, the Company recorded goodwill impairment of $26.9 million, of which $16.1 million represented a partial impairment of goodwill associated with operations in the United Kingdom and $10.8 million represented a full impairment of goodwill associated with operations in Juarez. As of October 1, 2005, the United Kingdom operations have remaining goodwill of $7.0 million.
     The impairment of goodwill associated with the United Kingdom arose primarily from a significant medical customer’s recently expressed intention to transfer future production by the end of fiscal 2006 from the United Kingdom to a lower-cost location. The impairment also reflects lowered expectations for the United Kingdom’s electronics manufacturing services industry in general. The impairment of goodwill associated with Juarez reflects a lowered forecast of near-term profits and cash flow associated with recent operational issues and an anticipated transfer of a major customer program to another Plexus manufacturing facility.
Bothell Facility Closure. During fiscal 2005, the Company incurred significant restructuring costs associated with the closure of the Bothell facility. The Company transferred key customer programs from the Bothell facility to other Plexus locations, primarily in the United States. This restructuring reduced the Company’s capacity and affected approximately 160 employees. The Company completed the closure of the Bothell facility during fiscal 2005 (as previously announced in fiscal 2004). During fiscal 2005 and 2004, we incurred total restructuring and impairment costs associated with the Bothell facility closure of approximately $9.3 million, which consisted of the following elements:

Plexus Corp.
Notes to Consolidated Financial Statements — Continued
$7.5 million was recorded in fiscal 2005 and consisted of $6.2 million for the facility lease, $1.1 million for employee retention costs and $0.2 million of other associated costs. The liability for the facility lease was recognized and measured at fair value for the future remaining lease payments subsequent to abandonment, less any estimated sublease income that could reasonably be obtained for the property;
$1.8 million was recorded in fiscal 2004 and consisted of $1.5 million for employee severance and $0.3 million for fixed asset impairments.
Shop Floor Data-Collection System Impairment.During fiscal 2005, the Company recorded a $3.8 million impairment of the remaining elements of a shop floor data-collection system. The Company had previously recorded a $1.7 million impairment related to the shop floor data-collection system in fiscal 2004 when it determined that certain elements would not be utilized in any capacity. During the first quarter of fiscal 2005, the Company extended a maintenance and support agreement for the data-collection system through July 2005 to provide it additional time to evaluate the remaining elements of the system. Based on the Company’s evaluation, it determined that the shop floor data-collection system was impaired. The Company determined that it would abandon deployment of these remaining elements of the shop floor data-collection system because the anticipated business benefits could not be realized.
Other Restructuring Costs. During fiscal 2005, the Company also recorded the following other restructuring and impairment costs:
$0.5 million, which consisted of $0.4 million associated with a workforce reduction and $0.1 million of asset impairments at the Juarez facility. The Juarez workforce reduction affected approximately 50 employees;
$0.3 million for severance associated with the elimination of a corporate executive position;
$0.2 million for a planned workforce reduction at the Maldon, England (“Maldon”) facility. As noted above, a significant customer in the United Kingdom intends to transfer future production from the United Kingdom to a lower-cost location by the end of fiscal 2006. As a result, the Company plans to consolidate its Maldon manufacturing operations into Kelso, Scotland and to focus the Maldon facility on fulfillment and service and repair.
$0.3 million of other restructuring costs.
Adjustments to Provisions: During fiscal 2005, the Company also recorded certain adjustments to previously recognized restructuring and impairment costs:
$0.4 million additional expense related to additional impairment of a closed facility in San Diego. During the first quarter of fiscal 2005, the Company subleased the remaining part of the San Diego facility, which resulted in the additional impairment to adjust the carrying value of the remaining part of the San Diego facility to its net present value of future sublease income;
a $0.4 million reduction in an accrual for lease obligations associated with a warehouse located in Neenah, Wisconsin (“Neenah”). The Neenah warehouse was previously abandoned as part of a fiscal 2003 restructuring action; however, the Company reactivated use of the warehouse in the second quarter of fiscal 2005;
a $0.3 million reduction in an accrual for lease obligations for one of the closed facilities near Seattle, Washington (“Seattle”). The Company was able to sublease one of the two closed Seattle facilities held under operating leases.

     On July 25, 2005, a significant customer in the United Kingdom announced that it was under investigation by the Office of Communication, a government regulator in the United Kingdom, and would postpone the further installation of its product in the United Kingdom until the regulatory situation became clearer. Consequently, future manufacturing for this customer is uncertain.
Fiscal 2004 Restructuring and Impairment Costs:During fiscal 2004, the Company recorded pre-tax restructuring and impairment costs oftotaling $9.3 million. The restructuring and impairment costs were primarily associated with adjustments to previously recognized restructuring actions, specifically, additional lease obligations for two previously abandoned facilities near Seattle Washington (the "Seattle facilities"),facilities. In addition, we incurred restructuring and impairment costs associated with the planned closure of the Company'sCompany’s Bothell Washington ("Bothell") engineering and manufacturing facility, the write-down of certain components of the Company's ERP software and the consolidationclosure of a satellite PCB-design office in Hillsboro, Oregon into another Plexus design office. 47 PLEXUS CORP. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED(“Hillsboro”).
Adjustments to Provisions: The originally estimated cost of the closure of the Seattle facilities was included in the Company'sCompany’s fiscal 2003 restructuring actions. The lease-related restructuring costs recorded in fiscal 2003 were based on future lease payments subsequent to abandonment, less estimated sublease income. As of September 30, 2004, the Seattle facilities had not been subleased. Based on the remaining term available to lease these facilities and the weaker than expected conditions in the local real estate market, the Company determined that it would most likely not be able to sublease the Seattle facilities. Accordingly, the Company recorded additional lease-related restructuring costs of $4.2 million in fiscal 2004. The Company also recorded $0.1 million of lease-related restructuring costs on a facility in Neenah, Wisconsin ("Neenah"(“Neenah”), which was also included in restructuring actions in fiscal 2003. EITF Issue No. 94-3 "Liability“Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)" is applicable to restructuring activities initiated prior to January 1, 2003, including subsequent restructuring cost adjustments related to such activities. As part of our efforts to align the Company's service offering with the evolving preferences of the Company's customers, the Company is in the process of replicating the focused capabilities of its
Bothell facility at other Plexus design and manufacturing locations that have higher productivity. The Company currently anticipates transferring key customer programs from the Bothell engineering and manufacturing facility to other Plexus locations primarily in the United States. This restructuring will reduce the Company's capacity by 97,000 square feet and affect approximately 160 employees. The Company currently expects the consolidation efforts will be completed by mid fiscal 2005, subject to customer timelines.Facility Closure: In fiscal 2004, the Company incurred restructuring costs of $1.8 million, which consisted of $1.5 million associated with employee terminations and $0.3 million associated with fixed asset impairments. In fiscal 2005, the Company anticipatescompleted the Bothell closure will resultwhich resulted in additional restructuring costs of $8.2$7.5 million which will consist of $2.2 million associated with employee terminations(see Fiscal 2005 Restructuring and $6.0 million associated with the facility lease.Impairment Costs above.)
Shop Floor Data-Collection System Impairment: The Company recorded a $1.7 million impairment related to certain ERP software, which primarily resulted from the Company'sCompany’s deployment strategy for a shop floor data-collection system. Some elements of the shop-floor data-collection system will not be deployed because the originally anticipated business benefits could not be realized. TheAlthough the Company continued to evaluate the remaining elements of the shop floor data-collection system, are still under evaluation. A change in the scope of this project could result in impairment of the remaining elements of the shop floor data-collection system. Assystem was taken in fiscal 2005.
Closure of September 30, 2004, the capitalized costs of the remaining elements of the shop floor data system total approximately $3.8 million and are included in Property, Plant and Equipment in the accompanying Consolidated Balance Sheet. Lastly, thea PCB-Design Office: The Company incurred approximately $1.5 million of other restructuring and impairment costs in fiscal 2004 primarily related to the consolidation of the Hillsboro satellite PCB-design office into another Plexus design office. The Hillsboro relatedHillsboro-related restructuring costs were primarily for employee termination costs and contract termination costs associated with leased facilities and software service providers. In fiscal 2005, the Company anticipates incurring an additional $0.1 million of restructuring costs related to employee relocations. Approximately 40 employees were affected by this restructuring.
Fiscal 2003 Restructuring and Impairment Costs:During fiscal 2003, the Company recorded pre-tax restructuring and impairment costs totaling $59.3 million. These costs resulted from the Company's actions taken in response to reductions in its end-market demand. Theserestructuring actions included closingthe closure of the San Diego and Richmond operating sites, the consolidation of several leased facilities re-focusing the PCB design group, a write-off of goodwill associated with San Diego, the write-down of underutilized assets to fair value at several locations, and the costs associated with reductions in the work force for manufacturing, engineering and corporate.various other actions. These measures were intended to align the Company'sCompany’s capabilities and resources with its customer demand. The Richmond facility was phased out of operations and sold in September 2003. Production was shifted to other Plexus operating sites in the United States and Mexico. The closure of Richmond resulted in a write-down of the building, a write-down of underutilized assets to fair value, and costs relating to the elimination of the facility's work force. Building impairment charges totaled $3.7 million related to the Richmond facility. 48 PLEXUS CORP. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED
San Diego Facility Closure: The San Diego facility was closed in May 2003. The closure of the San Diego facility resulted in a write-off of goodwill, the write-down of underutilized assets to fair value, and costs relating to the elimination of the facility'sfacility’s work force. Building impairment charges totaled $6.3 million related to the San Diego facility. During fiscal 2003, goodwill impairment for San Diego totaled approximately $20.4 million, of which $14.8 million was impaired as a result of a transitional impairment evaluation under SFAS No. 142 (see Note 1) and $5.6 million was impaired as a result of the Company'sCompany’s decision to close the facility.

Richmond Facility Closure: The Richmond facility was phased out of operations and sold in September 2003. Customer programs were shifted to other Plexus sites in the United States and Mexico. The closure of the Richmond facility resulted in a write-down of the building, a write-down of underutilized assets to fair value, and costs relating to severance for the facility’s work force. Building impairment charges totaled $3.7 million related to the Richmond facility.
Other Restructuring and Impairment Costs: Other fiscal year 2003 restructuring actions included the consolidation of several leased facilities, the write-down of underutilized assets to fair value and work force reductions, which primarily affected operating sites such as Juarez; Seattle, Washington; Neenah and the United Kingdom. It also impacted the Company'sCompany’s engineering and corporate organizations. The employee termination and severance costs for fiscal 2003 affectedwere for approximately 1,000 employees. Fiscal 2002 Restructuring and Impairment Costs: During fiscal 2002, the Company recorded restructuring and impairment costs totaling $12.6 million. These charges resulted from the Company's actions taken in response to reductions in its sales levels and capacity utilization and included a reduction in work force and the write-off of certain underutilized assets to fair value at several locations. The employee termination and severance costs for fiscal 2002 affected approximately 700 employees. The operating site closures included two owned facilities: one located in Neenah (the oldest of the Company's four facilities in Neenah) and the other located in Minneapolis, Minnesota ("Minneapolis"). These facilities were no longer adequate to service the needs of the Company's customers and would have required significant investment to upgrade. The Neenah facility was phased out of operations in February 2003 and is currently used for warehousing and administrative purposes. The Minneapolis facility was phased out of operation in July 2002 and sold in October 2002. There was no building impairment charge associated with the closure of these two facilities. Certain lease consolidations also occurred in fiscal 2002, which primarily affected the Company's facilities in Seattle and San Diego.

Deferred Compensation Plan:In September 1996, the Company entered into agreements with certain of its former executive officers under a nonqualified deferred compensation plan. Under the plan, the Company agreed to pay to these former executives, or their designated beneficiaries upon such executives'executives’ death, certain amounts annually for the first 15 years subsequent to their retirement. Life insurance contracts owned by the Company will fund this plan. Expense for this plan totaled approximately $0.4 million, $0.4 million and $1.8 million in fiscal 2004, 2003, and 2002, respectively.
     In fiscal 2000, the Company established an additional deferred compensation plan for its executive officers and other key employees (the "Executive“Executive Deferred Compensation Plan"Plan”). Under the Executive Deferred Compensation Plan, a covered executive may elect to defer some or all of his or her compensation into the plan, and the Company may credit the participant'sparticipant’s account with a discretionary employer contribution. Participants are entitled to payment of deferred amounts and any earnings, which may be credited thereon upon termination or retirement from Plexus. From fiscal 2000 through fiscal 2002, key employee salary deferrals in and discretionary contributions of the Company to the Executive Deferred Compensation Plan were effected through a split-dollar life insurance program, whereby Plexus entered into split-dollar life insurance agreements with various executive officers and key employees. Under these agreements, Plexus paid a minimum annual premium of $13,500 per policy, and such additional premiums as it determined. Upon the death of the covered employee, Plexus had an interest in the proceeds of the policy equal to the premiums paid. Premium payments made by the Company totaled approximately $0.1 million in fiscal 2002.
     In fiscal 2003, due to changes in the law, Plexus terminated thea split-dollar life insurance program and replaced it with a rabbi trust arrangement (the "Trust"“Trust”). The Trust allows investment of deferred compensation, held on behalf of the participants, into individual accounts and, within these accounts, into one or more designated investments. Investment choices do not include Plexus stock. During fiscal 2003, the cash value proceeds that were received upon the surrender of the split-dollar life insurance policies attributable to each plan participant totaled approximately $0.4 million and were placed into the Trust. In each of fiscal 2005, 2004 and 2003, the Company made a contributioncontributions to the participants'participants’ accounts in the amount of $13,500 per participant, or approximately $0.1 million in total in each period. The Trust assets are subject to the claims of the Company'sCompany’s creditors. As of October 1, 2005 and September 30, 2004, and 2003, the Trust assets totaled $1.1$1.9 million and $0.7$1.1 million, respectively and the related liability to the participants totaled approximately $1.2$2.1 million and $0.7$1.2 million, respectively. The Trust assets and the related liability to the participants are included in Other assets and Other liabilities, respectively, in the accompanying Consolidated Balance Sheets.
Other:The Company is not obligated to provide any post-retirement medical or life insurance benefits to employees. 12. CONTINGENCIES

     The Company (along with many other companies) has been sued by the Lemelson Medical, Education & Research Foundation Limited Partnership ("Lemelson"(“Lemelson”) related to alleged possible infringement of certain Lemelson patents. The complaint, which is one of a series of complaints by Lemelson against hundreds of companies, seeks injunctive relief, treble damages (amount unspecified) and attorney'sattorney’s fees. The Company has obtained a stay of action pending developments in other related litigation. On January 23, 2004, the judge in the other related litigation ruled against Lemelson, thereby declaring the Lemelson patents unenforceable and invalid. Lemelson has appealed this ruling.ruling, and on September 9, 2005 the U.S. Court of Appeals for the Federal Circuit affirmed the lower Court’s decision ruling that the Lemelson patents are unenforceable, and on November 16, 2005 denied a petition for rehearing. Lemelson may appeal this decision to the U.S. Supreme Court. The lawsuit against the Company remains stayed pending the outcome of that appeal. The Company believes the vendors from whom the patent equipment was purchased may be required to contractually indemnify the Company. However, based upon the Company's observation of Lemelson's actions in other parallel cases, it appears that the primary objective of Lemelson is to cause other parties to enter into license agreements. If a judgment is rendered and/or a license fee required, it is the opinion of management of the Company that such judgment, or fee, would not be material to the Company's financial position, results of operations or cash flows.outcome.
     In addition, the Company is party to other certain lawsuits in the ordinary course of business. Management does not believe that these proceedings, individually or in the aggregate, will have a material adverse effect on the Company'sCompany’s financial position, results of operations or cash flows. 52 PLEXUS CORP.

     Statement of Financial Accounting Standards No. 131, “Disclosures about Segments of an Enterprise and Related Information” (“SFAS No. 131”) establishes standards for reporting information about segments in financial statements. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or group, in assessing performance and allocating resources.

     As part of its annual assessment under SFAS No. 131, the Company operatesnoted changes in the economic performance and related long-term expectations of its operating segments during fiscal year 2005. This was especially acute in Europe and Mexico as evidenced by the $26.9 million goodwill impairment recorded in the third quarter of fiscal 2005 related to the Company’s UK and Mexico operations (See Note 9 — Restructuring and Impairment Costs). In addition, the Company continued to experience rapid sales growth in its Asian region during fiscal 2005. As a result, the Company has reclassified the manner in which it previously aggregated its operating segments from one business segment. Thesegment into four reportable geographical segments: United States, Asia, Mexico and Europe. As of October 1, 2005, the Company provides product realization services to electronic OEMs. The Company has three reportable geographic regions: North America, Europe and Asia. The Company has 19had 18 active manufacturing andand/or engineering facilities in North America, Europethe United States, Asia, Mexico and Asia to serve these OEMs.Europe.
     The Company uses an internal management reporting system, which provides important financial data to evaluate performance and allocate the Company'sCompany’s resources on a geographic basis. InterregionalNet revenues for segments are attributed to the region in which the product is manufactured or service is performed. The services provided, manufacturing processes used, class of customers serviced and order fulfillment processes used are similar and generally interchangeable across the segments. A segment’s performance is evaluated based upon its operating income (loss). A segment’s operating income (loss) includes its net sales less cost of sales and selling, general and administrative expenses, but excludes corporate and other costs, interest expense, other income (loss), and income tax expense. Corporate and other costs primarily represent corporate selling, general and administrative expenses, and restructuring and impairment costs. These costs are not allocated to the segments, as management excludes such costs when assessing the performance of the segments. Inter-segment transactions are generally recorded at amounts that approximate arm'sarm’s length transactions. The accounting policies for the regions are the same as for the Company taken as a whole.

     In the first, second and third quarters of fiscal 2005, the Company recorded pre-tax restructuring and impairment costs of $0.9 million, $10.6 million and $27.7 million, respectively. These costs were primarily associated with goodwill impairment, the closure of the Bothell facility and the write-down of certain ERP software.
     In the third and fourth quarters of fiscal 2004, the Company recorded pre-tax restructuring and impairment costs of $5.5 million and $3.8 million, respectively. These costs were primarily associated with lease obligations for two previously abandoned facilities near Seattle, Washington, the planned closure of the Bothell engineering and manufacturing facility, the write-down of certain ERP software and the consolidation of a satellite PCB-design office in Hillsboro, Oregon into another Plexus design office. In the fourth quarter of fiscal 2004, the Company also recorded a full valuation allowance on all of its U.S. deferred income tax assets. In the first, third and fourth quarters of fiscal 2003, the Company recorded pre-tax restructuring and impairment costs of $31.8 million, $19.6 million and $7.9 million, respectively. These costs resulted from our actions taken in response to reductions in our end-market demand. These actions included closing our San Diego and Richmond operating sites, the consolidation of several leased facilities, re-focusing our PCB design group, a write-off of goodwill associated with the San Diego operating site, the write-down of underutilized assets to fair value at several locations, and the costs associated with a reduction in work force in several operating sites, engineering and corporate groups. These measures were intended to align the Company's capabilities and resources with its lower demand. In addition, the Company adopted SFAS No. 142 for the accounting of goodwill and other intangible assets on October 1, 2002. Under the transitional provisions of SFAS No. 142, the Company identified reporting units with goodwill, performed impairment tests on the net goodwill and other indefinite-lived intangible assets associated with each reporting unit using a valuation date as of October 1, 2002, and determined that a pre-tax transitional impairment charge of $28.2 million was required at the San Diego and Juarez operating sites. The impairment charge was recorded in the first quarter of fiscal 2003 as a cumulative effect of a change in accounting for goodwill.
