About Plexus Corp. — The Product Realization Company

Plexus (www.plexus.com) is an award-winning participant in the Electronic Manufacturing Services (EMS) industry.

Plexus is passionate about its goal to be the best EMS company in the world at providing services for customers that
have mid-to-low volume requirements and a higher mix of products. To support our strategy, we have uniquely aligned
our business processes, workforce and financial metrics.

We operate flexible manufacturing facilities and processes designed to accommodate customers with multiple
product-lines and configurations as well as unique quality, reliability and regulatory requirements. Each of our
customers are supported by a multi-disciplinary customer team and one or more uniquely configured “focus factories”
supported by a supply-chain and logistics solution specifically designed to meet the flexibility and responsiveness
required to support that customer’s fulfillment requirements.

Our go-to-market strategy is also tailored to our target market sectors and business strategy, with business development
and customer management teams dedicated to each of the five sectors we serve. These teams are accountable to
understand sector participants, technology, unique quality and regulatory requirements and longer-term trends. These
teams also help set our strategy for growth in their sectors with a particular focus on expanding the services and value-
add that we provide customers.

In addition, our financial model is aligned with our business strategy, with our primary focus to earn a return on
invested capital (“ROIC”) in excess of our weighted average cost of capital (“WACC”). Lower manufacturing volumes,
flexibility and fulfillment requirements, our sector-based go-to-market strategy, and complex quality and regulatory
compliance requirements typically result in higher investments in inventory and selling and administrative costs
relative to our competitors. By exercising discipline to generate a ROIC in excess of our WACC, our goal is to ensure
that Plexus creates a value proposition for our shareholders as well as our customers.

Established in 1979, Plexus has approximately 7,900 employees located in 19 active facilities around the world. These
facilities are strategically located to support the global supply chain, manufacturing and engineering needs of OEMs in
our targeted market sectors. Plexus’ global footprint is outlined below:

ANNUAL MEETING OF SHAREHOLDERS 
FEBRUARY 4, 2009 

COMMONLY ASKED QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING 

Q: WHEN IS THIS PROXY MATERIAL FIRST AVAILABLE TO SHAREHOLDERS? 

A:  On  or  about  December  22,  2008,  Plexus  Corp.  (“Plexus”,  “we”  or  the  “Company”)  expects  to  mail  most 
shareholders a Notice of Internet Availability of Proxy Materials containing instructions on how to access the proxy 
material over the internet and to mail printed copies of the proxy material to the rest of our shareholders. 

Q: WHY DID I RECEIVE A NOTICE OF INTERNET AVAILABILITY OF PROXY MATERIALS INSTEAD 
OF A PRINTED COPY OF THE PROXY MATERIALS? 

A:  Pursuant to the rules recently adopted by the Securities and Exchange Commission, we are permitted to provide 
access  to  our  proxy  material  over  the  internet  instead  of  mailing  a  printed  copy  of  the  proxy  material  to  each 
shareholder.  As a result, on or about December 22, 2008, we expect to mail most shareholders a Notice of Internet 
Availability  of  Proxy  Materials  containing instructions regarding how  to access our proxy  material,  including  our 
proxy  statement  and  annual  report,  and  vote  via  the  internet.    If  you  receive  a  Notice  of  Internet  Availability  of 
Proxy  Materials  by  mail,  you  will  not  receive  a  printed  copy  of  the  proxy  material  unless  you  request  one  by 
following the instructions included in the Notice of Internet Availability of Proxy Material or provided below. 

Important Notice Regarding the Availability of Proxy Materials for 
 the Shareholder Meeting to Be Held on February 4, 2009 

The proxy statement and annual report are available at www.proxyvote.com.

At  www.proxyvote.com,  shareholders  can  view  the  proxy  material,  cast  their  vote  and  request  to  receive  paper 
copies of the proxy material by mail. 

Q:  HOW CAN SHAREHOLDERS REQUEST PAPER COPIES OF THE PROXY MATERIAL? 

A:  Shareholders may request that paper copies of the proxy material, including an annual report, proxy statement 
and proxy card, be sent to them without charge as follows:

Q: WHAT AM I VOTING ON? 

A:  At the annual meeting you will be voting on two proposals: 

1.  The election of nine directors to the board of directors to serve until Plexus’ next annual meeting and until 

their successors have been duly elected.  This year’s nominees are: 

(cid:2)  Ralf R. Böer 
(cid:2)  Stephen P. Cortinovis 
(cid:2)  David J. Drury 
(cid:2)  Dean A. Foate 
(cid:2)  Peter Kelly 

(cid:2)  John L. Nussbaum  
(cid:2)  Michael V. Schrock 
(cid:2)  Charles M. Strother, MD 
(cid:2)  Mary A. Winston 

2.  A  proposal  to  ratify  the  Audit  Committee’s  selection  of  PricewaterhouseCoopers  LLP  as  Plexus’ 

independent auditor for 2009. 

Q: WHAT ARE THE BOARD’S VOTING RECOMMENDATIONS? 

A:  The board of directors is soliciting this proxy and recommends the following votes: 

(cid:2)  FOR each of the nominees for election to the board of directors; and 

(cid:2)  FOR  the  ratification  of  the  Audit  Committee’s  selection  of  PricewaterhouseCoopers  LLP  as  Plexus’ 

independent auditors for 2009. 

Q: WHAT VOTE IS REQUIRED TO APPROVE EACH PROPOSAL? 

A:  To  conduct  the  annual  meeting,  more  than  50%  of  the  Plexus’  outstanding  shares  entitled  to  vote  must  be 
present in person or by duly authorized proxy. This is referred to as a “quorum.”  Abstentions and shares which are 
the  subject  of  broker  non-votes  will  be  counted  for  the  purpose  of  determining  whether  a  quorum  exists;  shares 
represented at a meeting for any purpose are counted in the quorum for all matters to be considered at the meeting. 

Assuming  a  quorum  is  present,  directors  are  elected  by  a  plurality  of  the  votes  cast  in  person  or  by proxy  by  the 
holders  of  Plexus  common  stock  entitled  to  vote  at  the  election  at  the  meeting.    “Plurality”  means  that  the 
individuals  who  receive  the  highest  number  of  votes  are  elected  as  directors,  up  to  the  number  of  directors  to  be 
chosen at the meeting.  Any votes attempted to be cast “against” a candidate are not given legal effect and are not 
counted as votes cast in the election of directors.  Therefore, any shares which are not voted, whether by withheld 
authority, broker non-vote or otherwise, have no effect in the election of directors except to the extent that the failure 
to vote for any individual results in another individual receiving a relatively larger number of votes. 

Ratification  of  PricewaterhouseCoopers  LLP  as Plexus’  independent auditors  will be determined  by  a  majority  of 
the shares voting on that matter, assuming a quorum is present.  Therefore, abstentions and broker non-votes will not 
affect the vote, except insofar as they reduce the number of shares which are voted. 

Q: WHAT IF I DO NOT VOTE? 

A:  The effect of not voting will depend on how your share ownership is registered. 

If you own shares as a registered holder and you do not vote, the shares that you do not vote will not be represented 
at the meeting and will not count toward the quorum requirement. If a quorum is obtained, then the shares that you 
have not voted will not affect whether a proposal is approved or rejected. 

If you are a shareholder whose shares are not registered in your name and you do not vote, then your bank, broker or 
other  holder  of  record  may  still  represent  your  shares  at  the  meeting  for  purposes  of  obtaining  a  quorum.  In  the 

2

absence of your voting instructions, your bank, broker or other holder of record may or may not vote your shares in 
its discretion depending on the proposal before the meeting. Your broker may vote your shares in its discretion on 
routine matters such as the election of directors and ratification of the Plexus’ independent auditors. 

Q: WHO MAY VOTE? 

A:  You  may  vote  at  the  annual  meeting  if  you  were  a  shareholder  of  record  of  Plexus  common  stock  as  of  the 
close of business on December 1, 2008, which is the “Record Date.”  As of the Record Date, Plexus had 39,327,417 
shares  of  common  stock  outstanding.    Each  outstanding  share  of  common  stock  is  entitled  to  one  vote  on  each 
matter presented.  Any shareholder entitled to vote may vote either in person or by duly authorized proxy.    

Q: HOW DO I VOTE? 

A:  We  offer  four  methods  for  you  to  vote  your  shares  at  the  annual  meeting—in  person;  via  the  internet;  by 
telephone; or by mail. You may vote in person at the annual meeting or authorize the persons named as proxies on 
the proxy card, John L. Nussbaum, Dean A. Foate and Angelo M. Ninivaggi, to vote your shares.  We recommend 
that you vote as soon as possible, even if you are planning to attend the annual meeting, so that the vote count will 
not be delayed. 

While  we  offer  four  methods,  we  encourage  you  to  vote  via  the  internet,  as  it  is  the  most  cost-effective  method 
available.    There  is  no  charge  to  vote  your  shares  via  the  internet,  though  you  may  incur  costs  associated  with 
electronic access, such as usage charges from internet access providers. If you choose to vote your shares via the 
internet, there is no need for you to request or mail back a proxy card. 

(cid:2)   By internet:  Go to www.proxyvote.com.  Please have either the notice or proxy card we sent to you in 

hand because each has your personal 12 digit control number(s) needed for your vote. 

(cid:2)   By telephone:  On a touch-tone telephone, call 1-800-690-6903.  Please have either the notice or proxy 
card we sent to you in hand because each has your personal 12 digit control number(s) 
needed for your vote. 

(cid:2)   By mail: 

If you only received a notice, please request written materials as provided on page 1 of 
the proxy statement.  Complete, sign, and date the proxy card and return it to the address 
indicated on the proxy card.  

If your shares are not registered in your name, then you vote by giving instructions to the firm that holds your shares 
rather than using any of these methods. Please check the voting form of the firm that holds your shares to see if 
it offers internet or telephone voting procedures. 

Q: WHAT DOES IT MEAN IF I RECEIVE MORE THAN ONE REQUEST TO VOTE? 

A: 
It  means  your  shares  are  held  in  more  than  one  account.  You  should  vote  the  shares  on  all  of  your  proxy 
requests. You may help us reduce costs by consolidating your accounts so that you receive only one set of proxy 
materials in the future. To consolidate your accounts, please contact our transfer agent, American Stock Transfer & 
Trust Company, LLC, toll-free at 1-800-937-5449. 

Q:  WHAT  IF  I  OWN  SHARES  AS  PART  OF  PLEXUS’  401(k)  SAVINGS  PLAN  AND/OR  EMPLOYEE 
STOCK PURCHASE PLANS? 

A:  Shareholders  who  own  shares  as  part  of  Plexus’  401(k)  Savings  Plan  (the  “401(k)  Plan”)  and/or  the  Plexus 
2000  and  2005  Employee  Stock  Purchase  Plans  (the  “Purchase  Plans”)  will  receive  a  separate  means  for  proxy 
voting  their  shares  held  in  each  account.    Shares  held  by  the  401(k)  Plan  for  which  participant  designations  are 
received will be voted in accordance with those designations; those shares for which designations are not received 
will be voted proportionally, based on the votes for which voting directions have been received from participants.  
Shares held in accounts under the Purchase Plans will be voted in accordance with management recommendations 
except for shares for which contrary designations from participants are received.

Q: WHO WILL COUNT THE VOTE? 

A:  Broadridge Financial Solutions, Inc. will use an automated system to tabulate the votes. Its representatives will 
also serve as the election inspectors. 

Q: WHO CAN ATTEND THE ANNUAL MEETING? 

A:  All shareholders of record as of the close of business on December 1, 2008, can attend the meeting.  However, 
seating is limited and will be on a first arrival basis. 

To attend the annual meeting, please follow these instructions: 

(cid:2)  Bring proof of ownership of Plexus common stock and a form of identification; or 
(cid:2)  If a broker or other nominee holds your shares, bring proof of ownership of Plexus common stock through 

such broker or nominee and a form of identification. 

Q: CAN I CHANGE MY VOTE AFTER I RETURN OR SUBMIT MY PROXY? 

A:  Yes. Even after you have submitted your proxy, proxies may be revoked at any time prior to the voting thereof 
either by written notice filed with the secretary or acting secretary of the meeting or by oral notice to the presiding 
officer during the meeting.  Presence at the annual meeting of a shareholder who has appointed a proxy does not in 
itself revoke a proxy. 

Q: MAY I VOTE AT THE ANNUAL MEETING? 

A: 
If you complete a proxy card or vote via the internet, you may still vote in person at the annual meeting. To 
vote  at  the  meeting,  please  either  give  written  notice  that  you  would  like  to  revoke  your  original  proxy  to  the 
secretary or acting secretary of the meeting or oral notice to the presiding officer during the meeting. 

If a broker, bank or other nominee holds your shares and you wish to vote in person at the annual meeting you must  
obtain a proxy issued in your name from the broker, bank or other nominee; otherwise you will not be permitted to 
vote in person at the annual meeting. 

Q: WHO IS MAKING THIS SOLICITATION? 

A:  This solicitation is being made on behalf of Plexus by its board of directors. Plexus will pay the expenses in 
connection with the solicitation of proxies.  Upon request, Plexus will reimburse brokers, dealers, banks and voting 
trustees, or their nominees, for reasonable expenses incurred in forwarding copies of the proxy material and annual 
report to the beneficial owners of shares which such persons hold of record.  Plexus will solicit proxies by mailing 
proxy  material  to  certain  shareholders  and  a  Notice  of  Internet  Availability  of  Proxy  Materials  to  all  other 
shareholders; for shareholders that do not receive the full proxy material, paper copies will be sent upon request as 
provided  above  and  as  provided  in  Plexus’  Notice  of  Internet  Availability  of  Proxy  Materials.    Proxies  may  be 
solicited  in  person,  or  by  telephone,  e-mail  or  fax,  by  officers  and  regular  employees  of  Plexus  who  will  not  be 
separately compensated for those services. 

To help assure that sufficient shares are represented at the meeting, Plexus also has engaged D.F. King & Co., Inc. 
to assist in the solicitation of proxies and provide related informational support and analysis, for a services fee and 
the reimbursement of customary out-of-pocket expenses that are not expected to exceed $25,000 in the aggregate. 

Q: WHEN ARE SHAREHOLDER PROPOSALS DUE FOR THE 2010 ANNUAL MEETING? 

A:  The Corporate Secretary must receive a shareholder proposal no later than August 24, 2009, in order for the 
proposal  to  be  considered  for  inclusion  in  our  proxy  materials  for  the  2010  annual  meeting.  The  2010  annual 
meeting  of  shareholders  is  tentatively  scheduled  for  February 10,  2010.    To  otherwise  bring  a  proposal  or 
nomination  before  the  2010  annual  meeting,  you  must  comply  with  our  bylaws.    Currently,  our  bylaws  require 
written notice to the Corporate Secretary between October 13, 2009, and November 7, 2009.  The purpose of this 

4

requirement  is  to  assure  adequate  notice  of,  and  information  regarding,  any  such  matter  as  to  which  shareholder 
action may be sought.  If we receive your notice after November 7, 2009, then your proposal or nomination will be 
untimely.  In  addition,  your  proposal  or  nomination  must  comply  with  the  procedural provisions  of our  bylaws.  If 
you do not comply with these procedural provisions, your proposal or nomination can be excluded. Should the board 
nevertheless choose to present your proposal, the named Proxies will be able to vote on the proposal using their best 
judgment. 

Q: WHAT IS THE ADDRESS OF THE CORPORATE SECRETARY? 

A:  The address of the Corporate Secretary is: 

Plexus Corp. 
Attn: Corporate Secretary 
55 Jewelers Park Drive

ELECTION OF DIRECTORS 

Plexus believes that it needs to attract and retain talented, focused, and motivated leadership to deliver the 
innovation and economic success its shareholders expect. For Plexus, the concept of leadership is not limited to the 
leadership within the company; leadership also includes the individuals who serve on Plexus’ board.   

In accordance with Plexus’ bylaws, the board of directors has determined that there shall be nine directors 
elected  at  the  annual  meeting  of  shareholders  to  serve  until  their  successors  are  duly  elected  and  qualified.    The 
persons  who  are  nominated  as  directors,  and  for  whom  proxies  will  be  voted  unless  a  shareholder  specifies 
otherwise, are named below.  If any of the nominees should decline or be unable to act as a director, which is not 
foreseen, the proxies will be voted with discretionary authority for a substitute nominee designated by the board of 
directors.  Plexus’ bylaws authorize up to nine directors, as determined by the board.  The Plexus board may expand 
the board up to the number of directors authorized in Plexus’ bylaws and elect directors to fill empty seats, including 
those created by an expansion, between shareholders’ meetings.

Board of Directors Meetings 

CORPORATE GOVERNANCE 

The board of directors held five meetings during fiscal 2008.  As part of these meetings, non-management 
directors  regularly  meet  without  management  present.    During  the  period  in  which  each  director  served,  each 
director  attended  at  least  75%  of  the  total  meetings  of  the  board  and  the  committees  of  the  board  on  which  that 
director  served.    The  Plexus  board  of  directors  conducts  an  annual  self-evaluation  process,  reviewing  the 
performance of each individual board member as well as the performance of the board as a whole. 

Plexus encourages all of its directors to attend the annual meeting of shareholders.  Plexus generally holds a 
board  meeting  coincident  with  the  annual  meeting  of  shareholders  to  minimize  director  travel  obligations  and 
facilitate their attendance at the shareholders’ meeting.  All then-serving directors attended the 2008 annual meeting 
of shareholders except for Mr. Kelly, who was detained in transit to the meeting due to inclement weather.

Director Independence 

As a matter of good corporate governance, we believe that the board of directors should provide a strong 
voice  in  the  governance  of  our  company.    Therefore,  under  our  corporate  governance  policies  and  in  accordance 
with Nasdaq Global Select Market rules, at least a majority of our directors must be “independent directors.”  

When the board of directors makes its determination regarding which directors are independent, the board 
first considers and follows the Nasdaq Global Select Stock Market rules.  The board also reviews other transactions 
and relationships, if any, involving Plexus and the directors or their family members or related parties; see “Certain 
Transactions”  herein  for  a  discussion  of  our  policy  regarding  such  transactions.    Plexus  expects  its  directors  to 
inform it of any transaction, whether direct or indirect through an immediate family member or any business entity 
controlled  by  any  of  them,  involving  the  director;  Plexus  also  surveys  directors  periodically  to  confirm  this 
information.  Plexus does not use any dollar amount to screen transactions that should be reported to the Company.  
The  board  reviews  the  information  submitted  by  its  directors  for  its  separate  determination  of  materiality  and 
compliance with Nasdaq and other standards when it determines independence. 

In determining independence for the coming year, the board considered two relationships that, upon review, 

the board did not believe affected the independence of the directors.  

(cid:2)

The law firm of which Mr. Böer is a partner and the Chairman and CEO, Foley & Lardner LLP, 
began representing the Company in a significant lawsuit and other matters in fiscal 2007.  During 
fiscal  2008,  Foley  &  Lardner’s  accrued  billings  for  fees  and  services  to  Plexus  were  $513,000.  
This  amount  represented  significantly  less  than  one-tenth of  one  percent  of  each  of  Foley  & 
Lardner’s and Plexus’ annual revenues.

(cid:2) Mr. Schrock is an executive officer of Pentair, Inc., which is a supplier to Plexus.  Pentair’s sales 
to Plexus in fiscal 2008 were $388,000, which represented less than one-tenth of one percent of 
each of Pentair’s and Plexus’ annual revenues.  It is anticipated that Pentair’s sales to Plexus will 
increase in the coming years.  

Based  on  the  applicable  standards  and  the  board’s  review  and  consideration,  the  board  of  directors  has 
determined  that  Messrs.  Böer,  Cortinovis,  Drury,  Kelly  and  Schrock,  Dr.  Strother  and  Ms.  Winston  are  each 
“independent” under applicable rules and guidelines.  Mr. Foate, as chief executive officer of the Company, and Mr. 
Nussbaum, who is a former chief executive officer of Plexus and receives retirement payments from Plexus, are not 
considered to be “independent.” 

Our independent directors have the opportunity to meet in executive session, without the other directors or 

management, as part of each regular board meeting. 

10

Board Committees 

The board of directors has three standing committees, all comprised solely of independent directors: Audit, 
Compensation  and  Leadership  Development,  and  Nominating  and  Corporate  Governance.    The  committees  on 
which our directors currently serve, and the chairs of those committees, are identified in the following table:

Messrs.  Foate  and  Nussbaum  are  not  “independent”  directors;  therefore,  they  are  not  eligible  to  serve  on  these 
committees under Nasdaq rules or the committees’ charters. 

Audit Committee 

The  Audit  Committee  met  eight  times  in  fiscal  2008.    The  Audit  Committee  chooses  the  Company’s 
independent  auditors  and  oversees  the  audit  process  as  well  as  the  Company’s  accounting  and  finance  functions. 
Among its other responsibilities, the Committee also oversees the Company’s ethics and whistle-blowing reporting 
programs.  See also “Report of the Audit Committee.” 

Audit Committee Financial Experts

 The board has determined that Messrs. Drury and Kelly and Ms. Winston are “audit committee financial 
experts” based on a review of each individual’s educational background and business experience.  For purposes of 
Securities  and  Exchange  Commission  (“SEC”)  and  Nasdaq  rules,  Messrs.  Drury  and  Kelly  and  Ms.  Winston  are, 
along with Mr. Cortinovis, the other member of the Audit Committee, “independent” of Plexus.  All members of the 
Audit Committee are “financially literate” and meet the other SEC and Nasdaq requirements for Audit Committee 
membership.  

Compensation and Leadership Development Committee 

The  Compensation  and  Leadership  Development  Committee  (in  this  subsection,  the  “Committee”)  held 
four meetings during fiscal 2008.  The Committee establishes the general compensation philosophies and plans for 
Plexus,  determines  the  CEO’s  and  other  executive  officers’  compensation  and  approves  grants  and  awards  under 
Plexus’ compensation plans.  The Committee also considers and makes recommendations to the board with respect 
to  other  employee  compensatory  plans  and  arrangements.    Further,  the  Committee  is  responsible  for  reviewing 
Plexus’ leadership structure, talent management efforts, leadership development and executive succession plans.  In 
addition  to  the  following  subsection,  see  also  “Compensation  Disclosure  and  Analysis”  and  “Compensation 
Committee  Report”  below  for  further  information  on  the  Committee’s  philosophies  and  practices,  and  its 
determinations in fiscal 2008. 

Overview of the Compensation Decision-Making Process 

In  accordance  with  the  philosophy  and  the  goals  described  below  in  “Compensation  Discussion  and 
Analysis,”  Plexus  compensates  its  executive  officers  through  salaries  and  various  other  compensation  plans.  The 
Committee considers many factors in its decision-making process about the compensation of Plexus' leadership and 
the design of compensation plans company-wide. 

11

 
 
 
 
 
 
 
 
 
 
When  determining  compensation  in  fiscal  2008,  as  in  past  years,  the  Committee  compared  the 
compensation  of  Plexus’  executive  officers  with  that  paid  by  other  companies  in  the  general  industries  in  which 
Plexus  recruits,  comparable  companies  in  the  electronic  manufacturing  services  industry,  companies  with  similar 
financial profiles and numerous general and electronics industry published surveys.  The Committee determined the 
peer  group  with  assistance  from  its  compensation  consultants,  Sibson  Consulting  (“Sibson”).    Companies  were 
chosen using filtering criteria, such as industry codes, peer groups, relative size and employee base; anomalies or 
special circumstances (primarily acquisitions or significant size differences) which caused certain companies to not 
be in fact comparable were also reviewed.  In addition, the Committee and Sibson also identified financial peers that 
were not in a similar business but which were similar in size and financial performance to Plexus. 

Our resulting core peer list for fiscal 2008 consisted of: 

(cid:2)
3Com Corporation 
(cid:2) Altera Corporation 
(cid:2) Amkor Technology, Inc. 
(cid:2) Arris Group, Inc. 

(cid:2) Atmel Corporation

(cid:2)
(cid:2) Molex Incorporated 

Linear Technology Corporation 

(cid:2) Novellus Systems, Inc. 

(cid:2)

Respironics, Inc. 

This  peer  group  was  also  used  for  fiscal  2007.    In  conjunction  with  the  peer  group  proxy  data,  the  Committee 
reviewed other information, such as a compensation assessment report compiled by Sibson.  The report addressed 
the following three issues: 

(cid:2)

(cid:2)

(cid:2)

The competitiveness of the pay opportunity for executive officers.

The appropriateness of the CEO’s pay and equity opportunities.

Sibson’s recommendations for pay for the top executive officers.

The report compared Plexus’ executive officer pay levels to those of comparable executive officers in similar roles 
at companies in Sibson’s survey database and to executive officers in similar roles at the peer companies. 

The  Committee  also  considers  data  comparing  the  currently  vested  equity  versus unvested  equity  for  the 
CEO  and  an  internal  fairness  assessment.    The  Committee  uses  the  vested  and  unvested  equity  information  to 
balance the level of existing awards with the desire to reward performance and to provide retention incentives.  The 
internal fairness assessment identifies the proportionality of the CEO’s pay to the pay of executives at other levels in 
the organization and compares this information with published survey data. 

In  addition  to reviewing  compensation  to  help  assure  that  it  provides  an  incentive  for  superior  Company 
performance, the Company and the Committee regularly review comparable information from peer group companies 
and  other  sources,  as  discussed  above,  to  maintain  a  competitive  compensation  package  that  aids  in  executive 
retention  and  fairly  compensates  the  executives  for  performance.    However,  it  does  not  aim  for  any  numerical  or 
percentile tests within this comparable information.  The Committee believes that it is important for it to take this 
information and then use its judgment in applying it in individual cases, rather than arbitrarily attempting to aim for 
a  particular  numerical  equivalence.    In  that  consideration,  the  Committee  discusses  total  compensation  (including 
outstanding  equity  awards)  for  all  executive  officers,  the  level  of  experience  and  leadership  each  provides,  and 
financial  and  personal  performance  results.    The  Committee  seeks  to  balance  different  types  of  compensation  in 
order to promote retention and strong Plexus performance.  The Committee believes this approach best results in a 
comprehensive and thoughtful compensation review process because it allows the Committee to use discretion when 
appropriate  in  responding  to  particular  circumstances.    The  Committee  intends  to  continue  these  practices  in  the 
future. 

12

Management  Participation.  Members  of  management,  particularly  the  CEO  and  human  resources 
personnel, regularly participate in the Committee’s meetings at the Committee’s request.  Management’s role is to 
contribute  information  to  the  Committee  and  provide  staff  support  and  analysis  for  its  discussions.    However, 
management does not make the final determination of the CEO’s or the other executive officers’ amount or form of 
executive compensation, nor does management make any recommendation for the CEO’s compensation.  The CEO 
does recommend compensation for the other executive officers to the Committee, subject to the Committee’s final 
decision.    To  assist  in  determining  compensation  recommendations  for  the  other  executive  officers,  the  CEO 
considers Plexus’ compensation philosophy and, in partnership with the human resources management team, utilizes 
the  same  compensation decision-making process  as  the Committee.    Decisions regarding  the  compensation  of  the 
CEO are made in executive sessions at which the Committee  members participate with select members of human 
resources management and staff to review competitive practices and overall plan expense.  The sessions generally 
focus on the CEO’s performance achievement and the elements of his compensation.  The Committee also discusses 
and reviews materials comparing the CEO’s compensation to peer group and survey data as well as Plexus’ overall 
performance relative to the companies in our peer group.  Materials presented also include a pay comparison of the 
CEO  to  our  other  executive  officers  and  a  review  of  the  CEO’s  vested  and  unvested  equity  grants  in  an  effort  to 
assess possible retention risks.

Use of Consultants.  The Committee uses outside compensation consultants to assist it in analyzing Plexus’ 
compensation programs and in determining appropriate levels of compensation and benefits.  The decision to retain 
consultants, and if so which consultant(s) to retain, is determined solely by the Committee.  Management has the 
authority  to  approve  compensation  consultant  fees  on  a  project  basis,  although  the  Committee  reviews  all  fees 
relating to executive compensation. 

Plexus  human  resources  personnel  meet  with  the  compensation  consultants  to  help  the  consultants 
understand  Plexus’  business  model,  organizational  structure  and  compensation  philosophy.    This  interaction 
provides the consultants with a framework to Plexus’ approach to compensation and its application.  As part of its 
staff support function, Plexus human resources personnel also discuss results and conclusions with the compensation 
consultants.    These  discussions  permit  Plexus  human  resources  personnel  to  be  aware  of  the  consultants’ 
recommendations and analysis, as well as to understand the rationale and methodology behind their conclusions. 

In fiscal 2007, the Committee retained Sibson to conduct a review of the executive compensation program.  
Sibson analyzed all of Plexus’ compensation programs, and the analysis was reviewed by the CEO, human resources 
management  and  the  Committee  Chair.    The  analysis  and  recommendations  made  by  Sibson  were  presented  in 
writing at a Committee  meeting in August 2007.  Sibson was asked to be available by conference call during the 
meeting to discuss any questions or issues that may have arisen as a result of their analysis and recommendations.  
Sibson’s  analysis  and  other  supporting  peer  group  and  published  competitive  data  compiled  by  Plexus’  human 
resources  personnel,  in  accordance with  Sibson’s  methodologies,  were used  by  the  Committee  in  determining  the 
appropriate  CEO  compensation.      The  Sibson  analysis  and  recommendations  were  also  utilized  by  the  CEO  and 
human  resources  management  in  conjunction  with  other  peer  group  and  published  survey  data  to  make 
recommendations regarding other executive officer compensation for fiscal 2008.    

The  Committee  felt  it  was  appropriate  to  add  a  different  perspective  to  compensation  discussions  after 
working with Sibson for two years and chose Watson Wyatt Worldwide (“Watson Wyatt”), a benefits and human 
resources consulting firm, as its compensation consultant for fiscal 2009.  In August 2008, Plexus’ internal human 
resources personnel conducted a competitive pay analysis similar to Sibson’s prior year analysis; that analysis was 
reviewed and evaluated by Watson Wyatt.  During the process of making fiscal 2009 compensation decisions, the 
Committee expanded its use of tally sheets and conducted an accumulated wealth analysis.  The tally sheets provide 
a  comprehensive  view  of  Plexus’  compensation  payout  exposure  under  various  termination  scenarios;  the 
Committee also used these tally sheets to evaluate the reasonableness of compensation as a whole.  The accumulated 
wealth  analysis  examines  the  CEO’s  accumulation  of  wealth  through  the  deferred  compensation  plan  and  annual 
equity awards. 

Neither  the  Company  nor  the  Committee  places  any  limitations  or  restrictions  on  its  consulting  firms  or 
their  reviews.    Sibson  and  Watson  Wyatt  have  been  retained  by  the  Company  only  for  projects  related  to  the 
Company’s executive and directors’ compensation programs.  The Company does provide substantive information 
about Plexus to help its consultants better understand the Company.  Human resources personnel also meet with the 
consultants to discuss the consultants’ conclusions as to Plexus’ executive pay practices, organizational matters, the

duties  and  responsibilities  of  particular  positions,  and  overall  conclusions  based  upon  Plexus’  compensation 
principles and goals. 

Compensation Committee Interlocks and Insider Participation

Each  of  the  members  of  the  Compensation  Committee  was  an  independent  director  and  there  were  no 
relationships or transactions in fiscal 2008 with those members requiring disclosure under SEC rules.  See, however, 
“Director  Independence”  above  for  certain  other  relationships  that  the  board  considered  when  determining  the 
independence of the directors. 

Nominating and Corporate Governance Committee 

The Nominating and Corporate Governance Committee (the “Nominating Committee”) met three times in 
fiscal 2008.  The Nominating Committee considers candidates for board membership, reviews the effectiveness of 
the  board,  makes  recommendations  to  the  board  regarding  directors’  compensation,  monitors  Plexus’  compliance 
efforts, and evaluates and oversees corporate governance and related issues.   

The Nomination Process 

The Nominating Committee generally utilizes a director search firm to identify candidates, but it evaluates 
those  individuals  on  its  own;  the  Committee  would  also  consider  candidates  suggested  by  outside  directors, 
management and/or shareholders.  Plexus’ corporate board member selection criteria include honesty and integrity, 
high level of education and/or business experience, broad-based business acumen, understanding of Plexus’ business 
and industry, strategic thinking and willingness to share ideas and network of contacts.  The Nominating Committee 
also considers the diversity of experiences, expertise and backgrounds among board members in identifying areas 
which could be augmented by new members.  To help assure that directors have the time to devote to their duties, 
Plexus  directors  may  not  serve  on  the  boards  of  more  than  three  additional  public  companies.    The  Nominating 
Committee  does  not  evaluate  proposed  nominees  differently  depending  upon  who  has  proposed  the  potential 
nominee.  

The  Nominating  Committee  would  consider  proposed  nominees  to  the  board  submitted  to  it  by 
shareholders.    If  a  qualified  candidate  expresses  a  serious  interest,  and  if  there  is  a  position  available  and  the 
candidate’s  experience  indicates  that  the  candidate  may  be  an  appropriate  addition  to  the  board,  the  Nominating 
Committee  reviews  the  background  of  the  candidate  and,  if  appropriate,  meets  with  the  candidate.    A  decision  is 
then made whether to nominate that person to the board. 

Ms.  Winston,  who  was  elected  to  the  board  of  directors  in  July  2008,  is  an  independent  director.  Ms. 
Winston  was  first  suggested  as  a  director-nominee  as  a  result  of  a  search  conducted  by  The  Prout  Group,  an 
executive recruiting firm retained by the Nominating Committee and paid a fee for researching and recommending 
potential candidates. 

If a shareholder wishes to propose someone as a director for the Nominating Committee’s consideration, 
the name of that nominee and related personal information should be forwarded to the Nominating Committee, in 
care  of  the  Secretary,  at  least  six  months  before  the  next  annual  meeting  of  shareholders  to  assure  time  for 
meaningful consideration by the Nominating Committee.  See also “Shareholder Proposals and Notices” for bylaw 
requirements for nominations.  Plexus has neither received nor rejected any candidates put forward by significant 
shareholders. 

Communications with the Board 

Any  communications  to  the  board  of  directors  should  be  sent  to  Plexus’  headquarters  office  in  care  of 
Plexus’ Secretary, Angelo Ninivaggi.  Any communication sent to the board in care of the Chief Executive Officer, 
the Corporate Secretary or any other corporate officer is forwarded to the board.  There is no screening process and 
any  communication  will  be  delivered  directly  to  the  director  or  directors  to  whom  it  is  addressed.    Any  other 
procedures which may be developed, and any changes in those procedures, will be posted as part of our Corporate 
Governance  Guidelines  on  Plexus’  website  at  www.plexus.com,  under  the  link  titled  “Investor  Relations”  then 
“Corporate Governance” (or at http://www.plexus.com/corporategovernanceguidelines.php).

Code of Ethics, Committee Charters and Other Corporate Governance Documents 

Plexus regularly reviews and augments its corporate governance practices and procedures.  As part of its 
corporate governance practices, Plexus has adopted a Code of Conduct and Business Ethics, Corporate Governance 
Guidelines and written charters for each of its board committees discussed above.  Plexus will be responding to and 
complying with related SEC and Nasdaq Global Select Stock Market directives as they are finalized, adopted and 
become effective.  Plexus has posted on its website, at www.plexus.com, under the link titled “Investor Relations” 
then “Corporate Governance” (or at http://www.plexus.com/corporategovernanceguidelines.php), copies of its Code 
of Conduct and Business Ethics, its Corporate Governance Guidelines, the charters for its Audit, Compensation and 
Leadership  Development,  and  Nominating  and  Corporate  Governance  Committees,  director  selection  criteria 
(included as an appendix to our Corporate Governance Guidelines) and other corporate governance documents.  If 
those  documents  (including  the  committee  charters,  the  Code  of  Conduct  and  Business  Ethics  and  the  Corporate 
Governance Guidelines) are changed, waivers from the Code of Conduct and Business Ethics are granted, or new 
procedures  are  adopted,  those  new  documents,  changes,  waivers  and/or  procedures  will  be  posted  on  Plexus’ 
corporate website at the address above.

Directors’ Compensation 

The Nominating and Corporate Governance Committee of the board of directors recommends, subject to 
board approval, compensation paid to non-employee directors, including equity awards to non-employee directors 
under  the  Plexus  2008  Long-Term  Incentive  Plan  (the  “2008  Long-Term  Plan”)  and,  formerly,  under  the  Plexus 
2005 Equity Incentive Plan (the “2005 Equity Plan”).  In determining the compensation paid to the non-employee 
directors,  the  Nominating  and  Corporate  Governance  Committee  considers  the  same  types  of  factors,  including 
comparison  with  peer  companies  and  company  performance,  that  are  considered  by  the  Compensation  and 
Leadership Development Committee when determining executive compensation. 

During fiscal 2008, each Plexus director who was not a full-time Plexus officer or employee (all directors 
except Mr. Foate) received an annual director’s fee of $35,000 plus meeting fees of $2,000 for each board meeting 
attended in person ($1,000 if attended other than in person) and an additional $1,000 for each committee meeting 
attended in person ($500 if other than in person).  In fiscal 2008, the chairs of each committee received additional 
fees  for  service  as  a  committee  chair;  the  chair  of  the  Audit  Committee  received  $12,000,  the  chair  of  the 
Compensation  and  Leadership  Development  Committee  received  $10,000  and  the  chair  of  the  Nominating  and 
Corporate  Governance  Committee  received  $7,000.    For  fiscal  2009,  the  annual  director’s  fee  will  increase  to 
$42,000 and the fees for chairing the Audit Committee and the Nominating and Corporate Governance Committee 
will  increase  to  $15,000  and  $10,000,  respectively.    Additionally,  in  certain  circumstances  directors  may  be 
reimbursed  for  attending  educational  seminars  or,  in  each  individual’s  capacity  as  a  director,  other  meetings  at 
Plexus’ behest. 

Directors  may  also  participate  in  the  2008  Long-Term  Plan,  which  permits  the  grant  of  options,  stock-
settled stock appreciation rights (“SARs”), restricted stock, which may be designated as restricted stock awards or 
restricted  stock  unit  awards,  performance  stock  awards,  and  cash  bonus  awards  to  officers,  key  employees  and 
directors.  In the past, options were granted to directors on or about December 1 of a year, continuing the date used 
in the formulaic provision in a predecessor plan.  Beginning for fiscal 2008 grants, the directors adopted a quarterly 
schedule for option grants to directors.  Under that schedule, the first grant is five days after the November board 
meeting  and  each  of  the  remaining  three  grants  is  on  the  third  business  day  after  the  Company’s  subsequent 
quarterly earnings release.  The exercise price is equal to the average of the high and low sale prices of Plexus stock 
on  the  Nasdaq  Global  Select  Market  on  the  grant  date.    One  half  of  the  options  granted  vest  immediately  on  the 
grant date and the balance vest on the first anniversary of the grant date.

123(R), “Shared Based Payments” (“SFAS 123(R)”), which requires us to recognize compensation expense for 
stock options and other stock-related awards granted to our employees and directors based on the estimated fair 
value  of  the  equity  instrument  at  the  time  of  grant.    Compensation  expense  is  recognized  over  the  vesting 
period.    Plexus  adopted  SFAS  123(R)  effective  October 5,  2005.    The  assumptions  used  to  determine  the 
valuation of the awards are discussed in footnote 11 to our consolidated financial statements.

Each  non-employee  director,  other  than  Ms.  Winston  (who  joined  the  board  on  July  28,  2008),  was  awarded 
options for 2,500 shares on each of November 23, 2007, January 28, 2008, April 28, 2008, and July 29, 2008.  
The options granted on November 23, 2007, are now fully vested.   One half of the options granted on each of 
the other dates vested immediately on the respective grant date and the balance vest on the first anniversary of 
the respective grant date.  Options granted to non-employee directors expire on the earlier of (a) ten years from 
the  date of grant, or (b) one year  after  termination of  service  as  a director.   On  November  19, 2008,  the first 
quarterly grant of options for fiscal 2009 was made; those options were granted at $14.17 per share, with other 
terms the same as the prior year’s options.   

(3)  Other than Mr. Nussbaum, the non-employee directors do not receive any additional benefits although they are 
reimbursed  for  their  actual  expenses  of  attending  board,  committee  and  shareholder  meetings.    For  Mr. 
Nussbaum,  this  represents  the  amounts  paid  to  him  in  fiscal  2008  under  his  deferred  compensation 
arrangements  plus  the  value  of  the  health  and  other  welfare  benefits,  as  well  as  Company  matching 
contributions to the 401(k) Plan, provided to him.  See the discussion immediately below. 

Compensation of Current and Former Executive Officers who Serve on the Board 

See  “Executive  Compensation” for  Mr. Foate’s  compensation  as  an  executive officer  of  Plexus generally 

and his employment and change in control agreements. 

Mr. Nussbaum is a former executive officer of Plexus.  He ceased being considered an executive officer or 
employee of Plexus when he retired as its Chief Executive Officer in 2002.  However, as a consequence of his many 
years  of  service  as  an  executive  officer  of  Plexus,  he  continues  to  be  compensated  under  deferred  compensation 
arrangements which were put in place during his service as an executive officer and as the non-executive Chairman 
of the Board. 

In  1996,  the  Compensation  and  Leadership  Development  Committee  established  special  retirement 
arrangements for Mr. Nussbaum and for two other executive officers and directors who subsequently retired.  Those 
arrangements were both to reward past service and to maintain an additional incentive for those officers’ continued 
performance on behalf of Plexus.  The related supplemental retirement agreement for Mr. Nussbaum is designed to 
provide specified retirement and death benefits to him in addition to those provided under the 401(k) Plan.  Plexus’ 
commitment  was  fully  funded  in  fiscal  2002.    Mr. Nussbaum  has  received  payments  under  the  special  retirement 
arrangements  since  2002,  including  payments  of  $301,068  for  fiscal  2007  and  $313,110  for  fiscal  2008.    Future 
payments may be adjusted, depending upon the performance of underlying investments. 

The contributions for Mr. Nussbaum’s special retirement arrangement are invested in life insurance policies 
acquired by Plexus on his life.  The supplemental retirement agreement  provides for a 15-year annual installment 
payment stream to Mr. Nussbaum.  Lump sum payments to Mr. Nussbaum based on policy cash values become due 
if at any time after a change in control Plexus’ consolidated tangible net worth drops below $35 million, or if the 
ratio  of  Plexus’  consolidated  total  debt  to  consolidated  tangible  net  worth  becomes  greater  than 2.5  to 1.    To  the 
extent that any of the payments constitute excess parachute payments subjecting Mr. Nussbaum to an excise tax, the 
agreement provides for an additional payment (the “gross-up payment”) to be made by Plexus to him so that after 
the payment of all taxes imposed on the gross-up payment, he retains an amount of the gross-up payment equal to 
the  excise  tax  imposed.    If  Mr. Nussbaum  dies  prior  to  receiving  all  of  the  15-year  annual  installment  payments, 
specified death benefit payments become due. 

For his service as Plexus’ non-executive Chairman of the Board, Mr. Nussbaum received $52,000 in fiscal 
2008  plus  health  and  other  welfare  benefits,  as  well  as  Company  matching  contributions  to  the  401(k)  Plan,  in 
addition  to  the  above  retirement  payments  and  his  regular  board  fees.    The  $52,000  fee  was  decreased  from  the 
$72,000  received  in  fiscal  2007  at  Mr.  Nussbaum’s  suggestion.    Since  his  retirement,  Mr. Nussbaum  has  been 
eligible to receive additional options or stock awards in his capacity as a non-employee director and has received the 
same awards as other non-employee directors under Plexus’ stock incentive plans.

Stock Ownership Guidelines 

Plexus believes that it is important for directors and executive officers to maintain an equity stake in Plexus 
to  further  align  their  interests  with  those of  our  shareholders.   Directors  and  executive  officers  must  comply  with 
stock ownership guidelines as determined from time to time by the board.  The ownership guidelines for directors 
currently require that directors must own 5,000 shares of common stock within five years of election or appointment 
to  the  board,  of  which  2,000  shares  must  be  owned  within  the  first  year  of  service.    Unexercised  stock  options 
(whether  or  not  vested)  do  not  count  toward  a  director’s  ownership  for  purposes  of  these  guidelines.    The  stock 
ownership  guidelines  for  executive  officers  are  discussed  at  “Compensation  Discussion  and  Analysis—Elements 
and Analysis of Direct Compensation—Equity Ownership Guidelines.”

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires Plexus’ officers and directors, and persons 
who  beneficially  own  more  than  10%  of  Plexus’  common  stock,  to  file  reports  of  ownership  and  changes  in 
ownership  with  the  Securities  and  Exchange  Commission.    These  “insiders”  are  required  by  SEC  regulation  to 
furnish Plexus with copies of all forms they file under Section 16(a). 

All publicly-held companies are required to disclose the names of any insiders who fail to make any such 
filing on a timely basis within the preceding fiscal year, and the number of delinquent filings and transactions, based 
solely on a review of the copies of the Section 16(a) forms furnished to Plexus, or written representations that no 
such  forms  were  required.    On  the  basis  of  filings  and  representations  received  by  Plexus,  Plexus  believes  that 
during fiscal 2008 Plexus’ insiders have complied with all Section 16(a) filing requirements which were applicable 
to them.

COMPENSATION DISCUSSION AND ANALYSIS 

The  Compensation  and  Leadership  Development  Committee  (in  this  section,  the  “Committee”)  of  the 
Plexus  board  of  directors  sets  general  compensation  policies  for  Plexus.    The  Committee  makes  decisions  with 
respect to compensation of the Chief Executive Officer and other Plexus executive officers and grants stock options, 
restricted stock units and other awards.  This section discusses the Committee’s executive compensation philosophy 
and decisions on executive compensation. 

Plexus  provides  further  detail  regarding  executive  compensation  in  the  tables  and  other  information 

included in the “Executive Compensation” section of this proxy statement. 

Fiscal 2008 Committee Highlights 

Among  the  key  compensation  issues  addressed  by  the  Committee  in  fiscal  2008,  which  are  discussed 

further below, were the following: 

(cid:2) New  Long-Term  Incentive  Plan.      The  2008  Long-Term  Plan  was  adopted  by  the  Committee  and  was 
approved  by  shareholders  at  the  2008  annual  meeting  of  shareholders.    The  2008  Long-Term  Plan  was 
adopted  due  to  the  limited  number  of  shares  remaining  for  issuance  under  the  2005  Equity  Plan  and  the 
Committee’s continued desire to provide long-term incentives to Plexus employees.   

(cid:2) New  Long-Term  Incentive  Mix  and  Issuance  Process.    In  fiscal  2008,  the  Committee  began  a  new 
approach  to  issuing  long-term  incentives  that  utilizes  a  portfolio  of  equity  awards  for  executive  officers: 
restricted  stock  units  (the  right  to  receive  shares  of  Plexus  common  stock  in  the  future,  if  conditions  are 
met)  (“RSUs”),  non-qualified  stock options (“options”),  and  long-term  cash  awards.      This  new  program 
balances the objectives of attracting and retaining key talent, promoting ownership among executives, and 
aligning  executives’  interests  with  those of shareholders  with  the  Company’s  cost  considerations  such  as 
expense,  dilution  and  tax  implications.    Previous  long-term  incentives  to  Plexus  executive  officers 
consisted of stock options only. 

Under this program, the Committee issues executives RSUs and long-term cash awards on an annual basis 
and makes annual determinations of option amounts, which are then granted on a quarterly basis.  Issuing 
options on a quarterly basis assists Plexus in managing the associated expense of these equity awards due to 
the historically high volatility of Plexus’ stock price.  Relative to a single annual grant, the quarterly grant 
process for options also reduces the risk to Plexus and its employees of experiencing either intermittently 
high or low exercise prices.  Plexus continued granting options, and commenced issuing RSUs, in the first 
fiscal quarter of 2008.  The Committee also decided to grant certain executive officers, and employees who 
are not executive officers, stock-settled stock appreciation rights (the right to receive, in shares of Plexus 
common  stock,  the  appreciation  value  of  a  stated  number  of  shares  of  Plexus  common  stock)  (“SARs”) 
rather than options. 

At the August 2007 meeting, the Committee approved a grant schedule to support the new quarterly grant 
process which states that each quarterly grant date will be three days subsequent to the release of Plexus’ 
quarterly  earnings,  not  including  the  day  of  the  release.    Since  this  methodology  is  specific  and  formula 
driven, there is no margin for subjectivity or consideration of the volatility of the stock price during this 
time period. 

(cid:2) Review of Agreements with Executive Officers.  In fiscal 2008, the Committee initiated a review of Mr. 
Foate’s  employment  agreement  as  well  as  the  Plexus  change  in  control  agreements  with  its  executive 
officers and other key employees.  In the review, the Committee sought to determine appropriate levels of 
potential benefits under those agreements and to assure complete compliance with recent Internal Revenue 
Code changes, particularly regarding Section 409A. 

As  a  result  of  the  review,  the  Committee  adopted  a  standard  methodology  for  determining  the  levels  of 
benefits  under  the  change  in  control  agreements  with  its  officers  and  employees,  which  levels  vary 
according to levels of responsibility.  Generally, that methodology left the levels of benefits unchanged for 

19

executive  officers.    The  Committee  believes  that  the  levels  of  potential  benefits  continue  to  promote 
Plexus’  interest  of  providing  security  for  its  key  employees  without  impeding  a  beneficial  potential 
acquisition or excessively benefiting executive officers.  The Committee retained the same overall level of 
benefits  under  Mr.  Foate’s  employment  agreement  as  it  determined  that  the  level  of  benefits  were 
appropriate.    The  Committee  also  made  changes  in  the  forms  of  the  change  in  control  agreements  to 
enhance their readability by employees as well as to assure compliance with tax laws. 

Executive Compensation Philosophy, Goals and Process 

The  Committee’s  philosophy  is  to  fairly  compensate  all  individuals,  including  executives,  for  their 
contributions to Plexus, appropriately motivate employees to provide value to Plexus’ shareholders, and consider the 
ability  of  Plexus  to  fund  any  compensation  decisions,  plans  or  programs.    Fair  compensation  must  balance  both 
short-term  and  long-term  considerations  and  take  into  consideration  competitive  forces,  best  practices,  and  the 
performance  of  Plexus  and  the  individual.    Compensation  packages  should  also  motivate  executives  to  make 
decisions and pursue opportunities that are aligned with the interests of our shareholders.  Finally, the Committee 
considers Plexus’ financial condition, the conditions in Plexus’ industry and end-markets, and the effects of those 
conditions on Plexus’ sales and profitability in making compensation decisions. 

Plexus’ executive compensation program is designed to provide a rational, consistent reward system that: 

(cid:2)

(cid:2)

attracts, motivates and retains the talent needed to lead a global organization; 
drives global financial and operational success that creates shareholder value; 
creates  an  ownership  mindset  and  drives  behaviors  that  improve  Plexus'  performance  and 
maximize shareholder value; and 
appropriately  balances  Company  performance  and  individual  contribution  towards  the 
achievement of success. 

For a discussion of the Committee’s decision-making process, its use of consultants and the role of Plexus’ 
executive  officers  and  staff,  see  “Corporate  Governance—Board  Committees—Compensation  and  Leadership 
Development  Committee—Overview  of  the  Compensation  Decision-Making  Process”  above  in  this  proxy 
statement. 

Elements and Analysis of Direct Compensation 

Overview of Direct Compensation 

Plexus  uses  three  primary  components  of  total  direct  compensation—salary,  annual  cash  incentive 
payments under the Variable Incentive Compensation Plan (“VICP”) and long-term equity-based awards under the 
2008 Long-Term Plan (and the 2005 Equity Plan, its predecessor).  Each of these components is complementary to 
the  others,  addressing  different  aspects  of  direct  compensation  and  seeking  to  motivate  employees,  including 
executive officers, in varying ways. 

(cid:2) Base  salary  is  intended  to  provide  compensation  which  is  not  “at  risk”;  however,  salary  levels  and 

subsequent increases are not guaranteed. 

(cid:2)

The opportunity to earn annual cash incentive payments under the VICP provides a substantial portion 
of  compensation  that  is  at  risk  and  that  depends  upon  the  achievement  of  measurable  corporate 
financial goals and individual objectives.  We use payouts from the VICP to provide further incentives 
for  our  executive  officers  and  employees  to  achieve  these  corporate  financial  goals  and  individual 
objectives. 

(cid:2) A  substantial  part  of  compensation,  which  is  also  at  risk,  is  longer-term  equity-based  compensation 
typically  awarded  to  date  in  the  form  of  stock  options  and,  beginning  in  fiscal  2008,  RSUs.    The 
Committee accompanies RSUs with time-vested long-term cash awards to defray the tax effects to the 
grantees upon the vesting of the RSUs as an incentive to those persons to continue to hold their shares 

20

upon vesting because they will not need to sell shares to raise cash to pay taxes; we also use long-term 
cash awards to round out the compensation package.  Those awards are intended to provide incentives 
to enhance corporate performance as well as to further align the interests of our executive officers with 
those  of  our  shareholders.    Total  compensation,  consistent  with  practices  in  our  industry,  places  a 
particular  emphasis  on  equity-based  compensation.    The  reported  values  of  the  long-term  incentive 
opportunities under equity plans can vary significantly from year to year as a percentage of total direct 
compensation because they are determined by valuing the equity-based awards on the same basis that 
we  use  for  financial  statement  purposes;  that  value  depends  significantly  on  our  stock  price  and  its 
volatility  at  the  time  of  the  awards.    Going  forward,  the  Committee  intends  to  continue  using  stock 
options, supplemented with RSUs and long-term cash awards. 

(cid:2)

For most non-executive officers who receive equity-based compensation, in fiscal 2008 the Committee 
began  to  grant  stock-settled  SARs  because  that  practice  would  promote  employee  share  ownership, 
reduce dilution and further the preservation of shares under Company plans.  The Committee plans to 
continue that practice. 

The  Committee  does  not  use  any  specific  numerical  or  percentage  test  to  determine  what  percentage  of 
direct compensation will be paid in base salary versus the compensation at risk through the VICP or equity-based 
compensation.    However,  the  Committee  believes  that  a  meaningful  portion  of  compensation  should  be  at  risk.  
VICP targets for executive officers other than the CEO ranged from 30% to 50% of base salary in fiscal 2008 with 
the opportunity to earn a bonus beyond the target if company financial goals were met or exceeded.  In the case of 
the CEO, the potential compensation at risk as a percentage of base salary was 100%, reflecting his overall greater 
responsibility for the corporation.  Long-term incentives for most executive officers are in the form of stock options, 
which contain an inherent amount of risk since no value is received unless there is an appreciation in stock price, 
and  RSUs  and  long-term  cash  awards  that  vest  based  on  continued  service.    After  determining  each  element,  the 
Committee also reviews the resulting total compensation to determine that it is reasonable as a whole. 

In addition, we provide all of our employees in the United States with various other benefits, such as health 
and life insurance.  We generally provide these benefits to our executive officers on the same basis as other salaried 
employees in the United States, although some benefit programs, as discussed elsewhere, are specifically targeted to 
our executive officers’ specific circumstances.  

Beyond  direct  compensation,  we  believe  it  is  important  to  provide  the  401(k)  Plan  as  a  means  for  our 
employees to save for their retirement.  To attract qualified employees and meet competitive conditions, Plexus also 
contributes to that plan.  As a consequence of Internal Revenue Code limitations on compensation which may be 
attributed to tax-qualified retirement plans, we have also developed a supplemental executive retirement plan for our 
executive officers to address their particular circumstances and promote long-term loyalty to Plexus until retirement. 

Plexus does not generally have employment agreements with its executive officers.  However, we do have 
such an agreement with our Chief Executive Officer in order to recognize his specific position, help assure Plexus of 
the continuing availability of his services and protect Plexus from post-employment competition by him. 

As  with  many  other  publicly-held  companies,  we  have  change  in  control  agreements  with  our  executive 
officers and certain other key employees.  As described further below, we reassessed these agreements in fiscal 2008 
and  revised  and  updated  them  to  reflect  tax  code  changes  and  to  better  coordinate  benefits.    We  have  these 
agreements in place to both help assure that executive officers will not be distracted by personal interests if Plexus 
were to be the subject of a potential acquisition, as well as to maintain their continuing loyalty to Plexus.  We also 
believe  that  competitive  factors  require  us  to  provide  these  protections  to  attract  and  retain  talented  executive 
officers and key employees. 

Base Salary 

(cid:2)

Purpose. Our base salaries are designed to provide regular compensation for the fulfillment of the duties 
and responsibilities associated with job roles.  Fixed salaries provide bi-weekly compensation to meet the 
living  needs  of  our  executives  and  their  families.    They  are  also  important  because  they  provide  most 

21

persons  with  a  starting  point  for  considering  compensation  when  we  seek  to  attract  and  retain  talented 
individuals. 

(cid:2)

Structure. The Company and the Committee use market-based comparisons, peer group analysis and other 
third-party  survey  data  to  establish  appropriate  base  salaries  for  its  executive  officers.    An  in-depth  total 
rewards  analysis,  including base  salary,  is  completed  annually  for  each  executive  position  using  the peer 
group and survey data as indicated above.  While we do not aim for particular numerical or percentage tests 
as compared to the peer group or the surveys, we generally target base salaries within ranges near market 
medians of those groups, with adjustments made to reflect individual circumstances. The effective date of 
any base salary increase is typically at or near the start of the fiscal year. 

(cid:2) Determination  Process;  Factors  Considered.  Prior  to  establishing  base  salary  increases  for  the  CEO  and 
confirming  salary  levels  for  other  executive  officers,  the  Committee  takes  into  consideration  various 
factors. These factors include compensation data from the proxies of our peer group, salary increase trends 
for executive base pay and other information provided in published surveys.  The Committee also considers 
the individual executive officers’ duties and responsibilities and their relative authority within Plexus. 

Executive officer base salary increases may include two components—competitive adjustments and merit 
increases.    If  executive  officer  salaries  are  found  to  fall  below  the  competitive  median  range  when  we 
compare them to our peer group and survey data, we consider increasing the salaries to a more competitive 
level.    In  some  cases  these  competitive  adjustments  may  take  place  over  a  multi-year  period  and  may 
depend  on  individual  performance.    If  executive  officer  salaries  are  found  to  be  at  an  appropriate  level 
when we compare them to the peer group and general industry survey data for the position, then a merit 
increase is provided if appropriate.  The merit increase amount is based on individual performance.  

With respect to increases in CEO base salary (as well as other compensation actions that impact our CEO), 
the  Committee  uses  this  input  and  meets  in  executive  session  to  discuss  appropriate  pay  positioning  and 
pay mix based on the data gathered.  With respect to the other executive officers, the CEO uses similar data 
and  submits  his  recommendations  to  the  Committee  for  final  determination.    The  data  gathered  in  the 
determination  process  helps  the  Committee  to  test  for  fairness,  reasonableness  and  competitiveness. 
However,  taking  into  account  the  compensation  policies  and  goals  and  a  holistic  approach  to  executive 
compensation packages, the Committee’s final determination may incorporate the subjective judgments of 
its members as well.   

(cid:2)

2008 Determinations.  For fiscal 2008, the Committee approved a base salary adjustment of $105,000 for
the CEO, increasing his annual salary to $675,000. This was an 18.4% increase from his fiscal 2007 base 
salary  and  reflected  strong  company  performance  in  fiscal  2007,  as  well  as  the  competitiveness  of  the 
CEO’s  salary  as  compared  to  the  market.    The  Committee  believed  that  the  CEO’s  compensation  was 
below  market  based  on  peer  group  survey  information,  particularly  in  view  of  the  Company’s  strong 
financial  performance.    Therefore,  it  approved  this  increase  to  provide  base  compensation  at  a  more 
competitive  level.    Our  CEO’s  base  salary  is  higher  than  that  of  other  executive  officers  because  of  his 
more extensive and challenging duties and responsibilities.

Increases for other executive officers varied from no increase to 12.5%, and were as follows for the other 
named  executive  officers:  Ms.  Jones—10.0%;  Mr.  Verstegen—4.0%;  Mr.  Ninivaggi—4.1%;  and  Mr. 
Lim—10.1%.   The  salary determinations  for  the  executive  officers  reflected  the  factors  discussed  above; 
some of the higher increases resulted from increased duties and responsibilities.  Ms. Jones was hired as an 
executive during fiscal 2007 and subsequently was named Chief Financial Officer.  Her initial salary was 
determined as part of the hiring process; her salary was below the salary of her predecessor, primarily as a 
reflection of her predecessor’s many years of experience as a chief financial officer, including with Plexus.  
Ms. Jones’ increase in fiscal 2008 reflected her promotion to CFO and the results of her initial time with 
Plexus.    The  increase  for  Mr.  Lim  reflected  his  promotion  to  an  executive  officer  position  late  in  fiscal 
2007 and the related increase in his responsibilities.  The compensation and benefits package of Mr. Lim 
also  reflects  regional  survey  data  of  the  Malaysian  markets.    Other  variations  between  the  executive 
officers  reflect  competitive  conditions  and  the  Committee’s  view  of  the  executive  officers’  duties, 
responsibilities and performance.

(cid:2)

2009 Determinations.  For fiscal 2009, the CEO’s salary is $750,000, an 11.1% increase from fiscal 2008.  
The Committee sought to reward the CEO for the strong financial results achieved in fiscal 2008, as well as 
to  keep  his  base  compensation  in  line  with  the  market  range  for  his  position.    The  fiscal  2009  salary 
increases for the other executive officers ranged from 3.0% to 20.0%.  Of those increases, the smaller ones 
reflected merit increases for performance over the past year when salaries were otherwise in line with the 
market;  larger  increases  represented  a  combination  of  competitive  adjustments  and  merit  increases.    The 
increases  for  the  other  named  executive  officers  were:    Ms.  Jones—10.7%;  Mr.  Verstegen—5.0%;  Mr. 
Ninivaggi—7.0%;  and  Mr.  Lim—10.0%.    For  Ms.  Jones  and  Mr. Lim,  the  increases  also  reflected  the 
significant  new  duties  they  assumed  in  fiscal  2008;  these  individuals  became  executive  officers  in  late 
fiscal 2007 and the scopes of their respective duties were not reflected in their previous salaries. 

Annual Incentive 

(cid:2)

(cid:2)

Purpose. Our annual cash incentive compensation plan, the VICP, is designed to reward employees for the 
achievement  of  important  corporate  financial  goals.  There  is  also  a  small  component  of  the  VICP  that 
rewards employees for the attainment of individual objectives. The establishment of the specific corporate 
financial  goals  is  derived  from  our  annual  financial  plan.    The  design  of  the  VICP  provides  incentives 
based on our direct performance, as distinguished from equity-based compensation, which is significantly 
affected by market factors that may be unrelated to our results. 

Plan Structure. The VICP provides annual cash incentives to approximately 2,500 participants, including 
our CEO and other executive officers. The VICP operates the same for all participants. Each participant has 
a targeted award that is expressed as a percentage of base salary.  For example, in fiscal 2008 the targeted 
award opportunity for the CEO was 100% of base salary, and the opportunities for other executive officers 
varied from 30% to 50% of base salaries.  Higher levels of duties and responsibilities within Plexus lead to 
higher  bonus  opportunities  under  the  VICP  because  the  Committee  believes  that  the  higher  ranking  the 
position,  the  more  influence  the  individual  can  have  on  corporate  performance.    In  addition,  market 
information  indicates  that  competitive  factors  make  relatively  higher  reward  possibilities  important  for 
those positions.  In fiscal 2008, Ms. Jones, our Chief Financial Officer, had the opportunity to earn up to 
50% of her salary as a VICP bonus at target; other officers’ percentages were 50% for Mr. Verstegen, 35% 
for Mr. Ninivaggi and 40% for Mr. Lim.   The opportunities for non-executive officer participants varied 
from 3% to 30% of base salaries.  For each participant, 80% of the targeted award is keyed to the corporate 
financial  goals;  the  remaining  20%  of  the  targeted  award  is  keyed  to  the  achievement  of  individual 
objectives. 

The  VICP  provides  for  payments  relating  to  corporate  financial  goals  both  below  and  over  the  targeted 
awards by establishing specific “threshold levels” of corporate performance at which payments begin to be 
earned and “maximum levels” beyond which no further payment is earned.  The payout at the “maximum 
level,” which is based solely on achieving the corporate financial goals, is 180% of the targeted award for 
the CEO and the other executive officers.   

Under the VICP, the Committee has the authority to adjust results, for example, to reflect acquisitions or 
unusual gains or charges.  No such discretion was used by the Committee in fiscal 2008. 

(cid:2)

2008 Plan Design – Company Goals

The specific corporate financial goals for fiscal 2008, each of which stood independently of the other with 
regard  to  award opportunities,  were revenue  and return  on  capital  employed  (“ROCE”).    The  goals were 
chosen  because  they  aligned  performance-based  compensation  to  the  key  financial  metrics  that  the 
Company used internally to measure its ongoing performance and that it used in its financial plans.  Our 
fiscal 2008 targets for these goals were set as part of the annual financial planning process.    For each of 
the  corporate  financial  goals,  we  also  established  specific  “threshold”  and  “maximum”  levels  of 
achievement as part of that process. 

For  these  purposes,  ROCE  is  defined  as  annual  operating  income  excluding  unusual  charges  and 
equity-based compensation costs divided by the five-point quarterly average of Capital Employed during 
the  year.    Capital  Employed  is  defined  as  equity  plus  debt  less  cash,  cash  equivalents  and  short-term 

23

investments.    The  Company  excludes  equity-based  compensation  costs  because  such  costs  can  influence 
results  due  to  external  market  factors.    Additionally,  ROCE  is  calculated  excluding  the  impact  of  any 
restructuring and/or non-recurring charges because these factors do not reflect the operating performance of 
the Company, which the VICP is intended to reward.   

No award is paid for any component of the VICP if Plexus incurs a net loss for the fiscal year (excluding 
non-recurring  or  restructuring  charges  and  equity-based  compensation  costs).    Awards  for  performance 
between  the  “threshold”  level  and  “targeted”  level  are  calculated  by  straight-line  interpolation,  as  are 
awards between the “targeted” level and the “maximum” level. 

For  fiscal  2008,  in  accordance  with  Plexus’  strategic  plan,  the  Committee  set  both  revenue  growth  and 
ROCE targets at aggressive, yet achievable levels to incent growth, but also to deter undue risk-taking.  The 
2008 revenue target represented approximately 19% growth over fiscal 2007 revenue.  The Committee felt 
this  target  was  challenging,  but  achievable,  based  on  industry  conditions  and  Plexus’  financial  plan.    To 
help assure that revenue growth would continue to result in shareholder value, the Committee set a ROCE 
target at a substantial level; the target level set for fiscal 2008 was below the level achieved in fiscal 2007 
to recognize the effects of product mix changes in fiscal 2007 that resulted in higher ROCE achievement.    
Since  the  ROCE  target  was  set  at  a  substantial  level,  the  Committee  emphasized  revenue  growth  when 
setting the VICP maximum threshold.    

The  following  table  sets  forth  the  fiscal  2008  financial  targets  and  potential  VICP  payout  amounts  (as  a 
percent of targeted VICP bonus) for the named executive officers, at the threshold, targeted and maximum 
performance levels.  In accordance with the VICP, the ROCE targets excluded the impacts of restructuring 
charges and equity-based compensation costs.

In  fiscal  2008,  revenue  was  $1,842  million  and  ROCE  was  26.6%.    Therefore,  based  on  the  corporate 
financial  goals  described  above,  Plexus  exceeded  the  target  level  for  both  revenue  and  ROCE  and  paid  
awards  to  executive  officers  and  other  employees  based  on  those  two  components.    Extrapolating  the 
results, payments based on revenue represented 54.4% as compared to the target of 40% for the revenue 
component.    Payments  based  on  ROCE  represented  40%,  as  target  ROCE  was  achieved.    Thus,  total 
payments based on revenue and ROCE represented 94.4% versus the target of 80% for corporate financial 
performance.  Plexus' actual performance in fiscal 2008 as compared to these targets is illustrated by the

2008 Plan Design – Individual Objectives

Individual  participants  typically  set  several  individual  objectives  for  the  plan  year,  which  are  developed 
with, reviewed by and approved by the participant’s manager.  Some of the individual objectives are shared 
by multiple executives when they team to focus on an objective.  Attainment of the individual objectives 
represents  20%  of  the  potential  targeted  award.    The  Committee  determines  and  approves  the  individual 
objectives established for the CEO.  The Committee also reviews and approves, with input from the CEO, 
the individual objectives established for the other executive officers.  The Committee’s assessment of all 
executive officers’ individual objectives is based on their likely impact on the achievement of the annual 
financial  plan  and  other  longer-term  strategic  priorities,  their  effect  on  shareholder  value  and  their 
alignment with one another.  

The following are summaries of the individual objectives for our named executive officers in fiscal 2008:  

– Dean A. Foate:  Mr. Foate’s individual objectives related to:  designing strategies to support 
global  expansion;  developing  and  implementing  an  annual  operating  system  that  efficiently 
and  logically  connects  the  Company’s  strategic  planning,  governance  and  organizational 
development  activities;  developing  a  process  to  evaluate  organizational  effectiveness  and 
leadership  talent;  creating  an  internal  process  to  evaluate  potential  acquisitions;  and 
establishing  expectations  and  a  vision  for  the  design  and  planning  of  a  new  corporate 
headquarters.

– Ginger  M.  Jones:    Ms.  Jones’  individual objectives related  to:    supporting global  expansion 
and  development;  creating  an  internal  process  to  evaluate  potential  acquisitions;  improving 
financial reporting and forecasting; developing and implementing an annual operating system 
that  efficiently  and  logically  connects  the  Company’s  major  planning,  governance  and 
organizational  development  activities;  optimizing  the  Company’s  overall  cash  cycle  and 
improving return on invested capital; redesigning annual cash incentive plans; and designing 
an investor relations program.  

– Michael  T.  Verstegen:    Mr.  Verstegen’s  individual  objectives  related  to:    supporting  global 
expansion  and  development;  improving  the  costing  process;  overseeing  the  development  of 
and  project  planning  for  a  new  corporate  headquarters;  redesigning  annual  cash  incentive 
plans; and creating an internal process to evaluate potential acquisitions.

– Angelo M. Ninivaggi:  Mr. Ninivaggi’s individual objectives related to:  recommending and 
designing  improvements  to  Plexus’  Enterprise  Risk  Management;  aligning  the  contract 
management  process  with  Plexus’  business  sectors;  implementing  a  new  sector  market 
development  and  customer  service  team;  creating  an  internal  process  to  evaluate  potential 
acquisitions; and implementing specified corporate governance improvements.

– Yong  Jin  Lim: Mr.  Lim’s  individual  objectives  related  to:    supporting  the  expansion  of 
operations in Asia; improving financial forecasting; promoting a “lean” culture; improving the 
costing process; monitoring customer feedback; and organizational development.

Achievement  of  individual  objectives,  for  which  there  was  a  potential  payout  equivalent  to  20%  of  the 
“targeted” bonus award, varied among executive officers from 14.5% to 20% of the total targeted amount.  
These percentages were based upon  the  Committee’s  determination  of  the degree  to which  the  executive 
achieved his or her objectives.  The CEO provided the Committee with an assessment of the performance 
of  all  of  the  executive  officers  other  than  himself  and  recommended  resultant  bonus  levels  based  on  the 
achievement by each executive officer of his or her individual objectives.  Individual determinations were 
as  follows  for  the  named  executive  officers:  Mr.  Foate—19.2%;  Ms.  Jones—17.8%;  Mr.  Verstegen—
18.7%; Mr. Ninivaggi—19.1%; and Mr. Lim—17.6%.

Long-Term Incentives 

(cid:2)

(cid:2)

(cid:2)

Purpose.  Our  long-term  incentives  are  designed  to  tie  the  major  part  of  our  key  executives’  total 
compensation opportunities to Plexus’ market performance and the long-term enhancement of shareholder 
value.  The 2008 Long-Term Plan and its predecessor, the 2005 Equity Plan, are also designed to encourage 
the long-term retention of these executives.   

Plan Structure.  The shareholder-approved 2008 Long-Term Plan and 2005 Equity Plan allow for various 
award  types,  including  options,  SARs,  restricted  stock,  RSUs,  and  performance  awards  (payable  in  cash 
and/or  equity).    Prior  to  fiscal  2008,  the  Committee  granted  only  time-vested  stock  options,  although  it 
continued to study the potential use of other forms of long-term incentive compensation.  The Committee 
has  generally  used  stock  options  because  of  their  prevalence  in  our  industry.    In  addition,  with  stock 
options, recipients receive value only when the value of the shares held by Plexus’ shareholders increases.  
The Committee’s policy is to not “back-date” equity grants and no equity grant was “back-dated” in fiscal 
2008.   

This  year,  the  Committee  approved  a  new  long-term  incentive  strategy  that  allows  for  use  of  a  portfolio 
approach  when  granting  awards.      The  Committee  intends  that  each  element  of  the  portfolio  addresses  a 
different aspect of long-term incentive compensation, as set forth below:  

–

Stock  options  and  stock-settled  SARs  provide  rewards  based  upon  the  appreciation  in  value  to 
shareholders  as  measured  by  the  increase  in  our  share  price;  the  Committee  uses  stock-settled 
SARs rather than options for less senior employees because stock-settled SARs do not require a 
cash outlay on exercise and promote employee share ownership.  Stock-settled SARs also allow 
the Committee to preserve shares available under the plans. 

– RSUs  provide  an  interest  in  the  value  of  the  Company’s  shares,  because,  even  though  they  vest 
over time, they provide recipients with a certain equity interest, assuming continued employment. 
RSUs further align executives’ interests with the interests of shareholders and provide a long-term 
ownership mentality as well as motivation to succeed in the long-term because the value of RSUs 
does not solely depend upon increases in the market price of our shares over a short-term period. 

–

Long-term cash awards that accompany grants of RSUs are intended to defray tax effects to the 
grantees upon the vesting of the RSUs as an incentive to those persons to continue to hold their 
shares upon vesting because they will not need to sell shares to raise cash to pay taxes; we also use 
long-term cash awards to round out the compensation package. 

Award  Determination  Process.    Pursuant  to  its  portfolio  approach,  the  Committee  distributes  the  entire 
value  of  each  grant  to  each  executive  officer  among  four  types  of  awards—options,  stock-settled  SARs, 
RSUs  and  long-term  cash  according  to  a  formula  based  on  the  duties  and  responsibilities  of  the  award 
recipient.  The awards are valued at their SFAS 123(R) value when making these determinations. For most 
executive  officers—those  with  the  most  senior  level  of  responsibilities  (and  including  all  of  the  named 
executive  officers)—the  Committee  uses  a  distribution  formula  weighted  toward  stock  options,  so  as  to 
particularly promote increasing shareholder value; for the remaining executive officers and for those at the 
manager or director level, Plexus uses a distribution weighted toward stock-settled SARs.  The allocation 
formulas for these two groups are illustrated in the pie charts below: 

Senior Executive Officers

Long-Term Cash 
15%

RSUs
25%

Options
60%

RSUs
30%

Stock-settled
SARs
70%

26

Other employees who receive awards receive 100% of the value of their awards in stock-settled SARs. 

– Option/SARs  Pool  Determination.    Each  year  the  Committee  is  presented  a  recommended  total 
pool  of  options  and  stock-settled  SARs  to  be  awarded  to  eligible  participants.    The  Committee 
reviews  the  estimated  cost  of  the  pool,  as  well  as  the  recommended  grant  guidelines;  the 
Committee  uses  a  relatively  constant  pool  size  because  it  wishes  to  control  the  expense  to  the 
Company under SFAS 123(R) and manage dilution to shareholders.  The options and stock-settled 
SARs  granted  to  executive  officers  and  employees  in  fiscal  2008  were  for  a  total  of  492,366 
shares.  That amount excludes options for 70,000 shares awarded to the non-employee directors.  
The total grant in fiscal 2008 was greater than the amount granted in fiscal 2007, because quarterly 
grants were made only in the third and fourth fiscal quarters of fiscal 2007. 

– Option/SARs  Pool  Allocation.    The  Committee  determines  the  grants  for  the  CEO  and  other 
executive  officers.    Those  awards  are  developed  by  considering  the  total  pool  of  options  to  be 
awarded,  which  is  recommended  by  management,  subject  to  the  Committee’s  review  and 
approval.  The Committee chooses a grant size that balances the need to provide fair compensation 
with the desire to keep related compensation expense relatively stable from period to period and to 
manage  shareholder  dilution.    The  numbers  granted  to  each  executive  officer  primarily  vary 
according  to  the  executive  officers’  duties  and  responsibilities  within  the  Company  and  also 
include a review of performance.  Those in positions with more responsibility tend to receive more 
options to reflect their role in the Company and the market comparisons for their compensation.  
Also,  as  discussed  above,  for  the  CEO,  the  Committee  uses  the  vested  and  unvested  equity 
information to balance the level of existing awards with the desire to reward performance and to 
provide retention incentives. The CEO provides the Committee with initial recommendations as to 
the number of options to be granted to each executive officer other than himself.  The remaining 
pool, which is comprised of stock-settled SARs (and RSUs as discussed below), is then allocated 
to  high-performing  key  employees  based  upon  recommendations  by  executive  officers  in 
accordance  with  a  grant  range  grid,  which  assigns  a  range  of  stock-settled  SARs  grant  sizes  to 
each employee responsibility level.  For fiscal 2008, options for 75,000 shares were granted to the 
CEO,  and  options  for  88,500  shares  were  granted  to  the  other  executive  officers  as  a  group.  
Additionally, stock-settled SARs for 6,050 shares were granted to other executive officers.  

– RSU and Long-Term Cash Award Determinations.  Once the Committee determines the levels of 
options to award, it then grants RSUs and long-term cash awards in accordance with the formulas 
discussed above, in order to effectively balance the motivations provided by the different types of 
awards.  A similar process occurs for those receiving stock-settled SARs.  In fiscal 2008, 104,313 
RSUs  were  granted  to  executive  officers  and  key  employees,  along  with  $705,375  in  long-term 
cash  awards.    As  noted  above,  RSUs  and  the  corresponding  long-term  cash  awards  were  not 
granted in previous years.  

2008 Awards.  Using these principles, in fiscal 2008, the Committee made total grants of options and an 
annual grant of RSUs and long-term cash to the named executive officers as follows:

Options  vest  in  two  annual  increments  and  grants  of  RSUs  and  long-term  cash  awards  vest  on  the  third 
anniversary of the grant, all subject to early vesting on a change in control. 

Basis  for  Determination  of  Timing  of  Grants.    The  Committee  now  makes  quarterly  option  grants  rather 
than annual grants due to the volatility of the stock market, including for Plexus stock in particular, since 

27

(cid:2)

(cid:2)

granting  stock  options  all  on  one  date  in  the  year  can  make  the  strike  price  and  related  expense  vary 
significantly in ways that do not necessarily reflect long-term performance of Plexus stock.   

The Committee’s formula to support the quarterly grant strategy states that the grant date will occur three 
days subsequent to the release of quarterly earnings, not including the day of the release.  The Committee 
uses  a  future  date,  as  is  permitted  by  the  2008  Long-Term  Plan  and  the  2005  Equity  Plan,  because  that 
minimizes the opportunity to choose a date based upon market performance known or knowable at the time 
of grant.  Those plans provide that the exercise price of a stock option is not less than the fair market value 
on the stock option grant date.  New hire option and stock-settled SARs grants are determined at or around 
the time of hire, and commence on the next quarterly grant date following the date of hire. 

Grants of RSUs and long-term cash awards are made annually, at the same time as the initial option and 
stock-settled SARs grants for the fiscal year. 

Equity  Ownership  Guidelines. To  complement  the  2005  Equity  Plan’s  and  the  2008  Long-Term  Plan’s  goals  of 
increasing the alignment between the interests of management and shareholders, the Committee adopted executive 
stock ownership guidelines. These guidelines require most executive officers, including all of the named executive 
officers  in  the  “Summary  Compensation  Table”  below,  to  own,  at  a  minimum,  Plexus  stock  with  a  market  value 
equal  to  one  times  their  annual  base  salary.    There  is  no  specific  time  requirement  to  meet  these  guidelines.  
However, an executive officer is generally not permitted to sell Plexus shares that were acquired while an executive 
officer  until  the  ownership  requirement  is  met;  there  are  exceptions,  including  financing  the  exercise  of  stock 
options when the shares will be held or with prior approval under special circumstances. 

Benefits. Consistent with competitive practice,  the Committee approves certain perquisites and other benefits for 
our CEO and the other executive officers in addition to those received by all U.S. salaried employees.  Substantially 
all  U.S.  employees  receive  health  insurance  benefits.    In  addition,  the  other  benefits  for  certain  of  our  executive 
officers are: a flexible perquisite benefit valued at up to $10,000 per calendar year,  which amount is grossed up for 
taxes, to be used for miscellaneous expenses such as personal financial planning, spouse travel costs in connection 
with business-related travel, club memberships and/or tax and estate advice; a company car; and additional disability 
insurance for the CEO, due to the dollar limits of the Company’s disability insurance policies.  As a result of local 
law and custom, different but comparable insurance programs and other benefits may apply to personnel, including 
Mr. Lim, who are located in countries outside of the United States. 

Elements and Analysis of Retirement and Other Compensation 

In addition to direct compensation, Plexus uses several other types of compensation, some of which are not 
subject  to  annual  Committee  action.    These  include  retirement  plans,  other  stock  ownership  opportunities,  and 
employment  or  change  in  control  agreements.
These  are  intended  to  supplement  the  previously  described 
compensation methodologies by focusing on long-term employee security and retention.  Certain of these plans allow 
employees to acquire Plexus stock. 

Retirement Planning – 401(k) Plan

(cid:2)

(cid:2)

Purpose.  Plexus maintains the 401(k) Plan, which is available to substantially all U.S. salaried employees, 
to help our employees provide for their retirement.  The 401(k) Plan includes a Plexus stock fund as one of 
its choices to permit employees to maintain Plexus ownership if they wish.

Plan  Structure.    The  401(k)  Plan  allows  employees  to  defer  a  portion  of  their  annual  salaries  into  their 
personal  accounts  maintained  under  the  401(k)  Plan.    In  addition,  Plexus  matches  a  portion  of  each 
employee’s  contributions,  up  to  a  maximum  of  $5,750  per  calendar  year.    Employees  have  a  choice  of 
investment vehicles, including a Plexus stock fund, in which to invest those funds.  

Supplemental Executive Retirement Plan 

(cid:2)

Purpose.    Plexus’  supplemental  executive  retirement  plan  (the  “SERP”)  is  a  deferred  compensation  plan 
which allows participants to defer taxes on current income.  Most executive officers, including all of the 

28

named executive officers other than Mr. Lim, participate in this program.  Additionally, the Company can 
credit a participant’s account with a discretionary employer contribution.  Such opportunities are common 
practice in general industry.  The SERP also provides a vehicle for the Company to restore the lost deferral 
and matching opportunity caused by tax regulation limitations on such deferrals and matched contributions 
for highly compensated individuals.  The Committee believes that further retirement compensation through 
the SERP is appropriate to meet the market for executive compensation and to provide a stronger incentive 
for executives to remain with Plexus through retirement.

(cid:2)

Plan Structure. During fiscal 2000, the Committee established the current SERP arrangement.  Under this 
plan,  several  key  executives,  including  the  named  executive  officers  (other  than  Mr.  Lim),  may  elect  to 
defer some or all of their compensation.  Plexus may also make discretionary contributions.  Additionally, 
Plexus  has  purchased  Company-owned  life  insurance  on  the  lives  of  certain  executives  to  meet  the 
economic  commitments  associated  with  this  plan.    A  rabbi  trust  arrangement  was  established  under  this 
plan and allows investment of deferred compensation amounts on behalf of the participants into individual 
accounts  and  within  these  accounts,  into  one  or  more  designated  mutual  funds  or  investments.  These 
investment choices do not include Plexus stock. Deferred amounts and any earnings which may be credited 
become payable upon termination or retirement from Plexus.  

(cid:2)

Fiscal 2008 Plan Activity. 

– Contribution Formula.  Under a funding plan adopted by the Committee in fiscal 2006, the SERP 
provides for an annual discretionary contribution of the greater of (a) 7% of the executive’s total 
targeted  cash  compensation,  minus  Plexus’  permitted  contributions  to  the  executive  officer’s 
account in the 401(k) Plan, or (b) $13,500.  Total targeted cash compensation is defined as base 
salary  plus  the  targeted  annual  incentive  plan  bonus  at  the  time  of  the  Company’s  contribution.  
The  Committee  adopted  this  approach  for  discretionary  contributions  to  reflect  competitive 
practices based on the research, analysis and recommendations of Towers Perrin, its compensation 
consultant for that program.

–

–

Employer Contributions.  For fiscal 2008, the total employer contributions to the SERP accounts 
was  $238,131  for  all  participants  as  a  group,  including  $88,750  for  the  CEO  but  excluding  the 
special contribution discussed below.  See footnote 4 to the “Summary Compensation Table.”

Special Contribution.  The SERP also allows the Committee to make discretionary contributions.  
The  Committee  did  not  make  any  such  contributions  in  fiscal  2008  to  the  named  executive 
officers, although the Committee  made a special contribution of $265,500 to a  former executive 
officer of Plexus upon his permanent leave in recognition of his prior service and contributions to 
the Company. 

(cid:2)

Foreign Arrangements.  Since Mr. Lim is not a United States resident, he does not participate in the SERP 
or  the  401(k)  Plan.    Rather,  he  participates  in  the  Employees  Provident  Fund  which  is  mandated  by 
Malaysian law.  Under law, minimum contributions of 12% of an employee’s wages (salary plus bonus) are 
required  to  be  made  by  an  employer;  Plexus  chose  to  make  a  contribution  of  17%  in  fiscal  2008  in  Mr. 
Lim’s case since it is Plexus’ practice in Malaysia to make higher contributions than the statutory minimum 
for personnel with relatively high levels of seniority and responsibility.

Employee Stock Purchase Plans 

(cid:2)

Purpose, Structure and Termination.  The Committee believed it was useful to provide all employees with 
opportunities to own Plexus stock and therefore established the Purchase Plans as a means of facilitating 
purchases  with  a  small  discount  available  to  substantially  all  employees  in  the  United  States  and  certain 
other  locations  on  the  same  terms.    The  Purchase  Plans  allowed  employees  to  purchase  stock  at  a  5% 
discount from the fair market value of the shares at the end of the purchase period.  However, the Purchase 
Plans’  utility  and  attractiveness  diminished as  a  result  of  subsequent  accounting  changes.    Therefore,  the 
Committee terminated further purchases under the Purchase Plans in January 2008.

Employment and Change in Control Agreements 

(cid:2)

(cid:2)

Purpose.    Plexus  maintains  an  employment  agreement  with  our  Chief  Executive  Officer  in  order  to 
recognize  the  importance  of  his  position,  to  help  assure  Plexus  of  continuing  availability  of  Mr.  Foate’s 
services  over  a  period  of  time,  and  to  protect  the  Company  from  competition  post-employment.    All 
executive  officers  (with  the  exception  of  Mr.  Foate,  who  has  change  in  control  provisions  as  part  of  his 
employment agreement) have change in control agreements, to both help assure that executive officers will 
not be distracted by personal interests in the case of a potential acquisition of Plexus as well as to maintain 
their continuing loyalty.

The  Agreements.    Mr.  Foate’s  employment  agreement  is  described  below  in  “Executive  Compensation –
 Employment Agreements and Potential Payments Upon Termination or Change in Control – Mr. Foate’s 
Employment  Agreement.”    The  change  in  control  agreements  with  our  executive  officers  (with  the 
exception of Mr. Foate) are described below in “Executive Compensation – Employment Agreements and 
Potential Payments upon Termination or Change in Control – Change in Control Arrangements.”  Please 
refer to those discussions for a further explanation of those agreements.

In fiscal 2008, we entered into a new employment agreement with Mr. Foate and adopted a new form of 
change  in  control  agreement  for  all  other  employees  covered  by  those  agreements,  including  the  other 
executive officers.  These new agreements did not substantially change the level of benefits payable under 
the prior agreements; we adopted the agreements to better comply with the provisions of Section 409A of 
the  Internal  Revenue  Code, to  better  coordinate  benefits, and  to  enhance  the  readability  of  the  change  in 
control  agreements.    Prior  to  entering  into  the  new  employment  agreement,  Mr.  Foate  had  separate 
employment and change in control agreements; as part of the changes, we incorporated change in control 
provisions  into  Mr.  Foate’s  employment  agreement  rather  than  having  him  enter  into  a  new  change  in 
control agreement.  The potential change in control benefits payable under Mr. Foate’s new employment 
agreement  stayed  substantially  the  same  as  those  that were  payable  under  his  previous  change  in  control 
agreement.   

(cid:2) Determination  of  Benefit  Levels.

In  general,  the  change  in  control  agreements  with  executive  officers 
provide  that,  upon  termination  in  the  event  of  a  change  in  control,  executive  officers  will  receive 
compensation equaling two or three times annual salary plus targeted bonus, a continuation of health and 
retirement benefits for that period, and a gross-up payment for excise taxes.  (The executive officers with 
three  year  agreements  are  generally  those  in  more  senior  positions,  with  greater  seniority  in  those 
positions.)    In  addition,  under  the  2008  Long-Term  Plan  and  the  2005  Equity  Plan,  upon  a  change  in 
control,  all  unvested  awards  will  automatically  vest  for  all  award  holders.    Certain  other  key  employees 
also have change in control agreements on substantially the same terms, although generally with only one 
to two years’ coverage.  The Committee believes it is important that executives and key employees have 
protection of their livelihood in the face of a potential acquisition to help them maintain their focus on the 
best interests of the Company’s shareholders even if it may have adverse consequences to them personally.   

The  Committee  set  these  benefit  levels  in  2008,  when  the  agreements  were  updated  and  revised.    The 
Committee  determined  that  the  level  of  benefits,  combined  with  the  “double  trigger”  requiring  both  a 
change  in  control  and  a  termination  of  employment,  continue  to  provide  an  appropriate  balancing  of  the 
interests  of  the  Company,  its  shareholders  and  its  executives.      Benefit  levels,  particularly  the  use  of  a 
measurement of up to three-times salary and a gross up for excise taxes, were adopted by the Committee at 
that time because it believed that, while the amounts were generous to the executive officers, they were in 
line with competitive standards and Plexus’ overall compensation policy and level of other benefits, as well 
as necessary and appropriate to attract and retain executive talent, particularly since most executives do not 
have  an  employment  agreement.    The  Committee  also  believed  that  it  was  general  market  practice  to 
provide that unvested awards will vest on a change in control, which is the case under the 2008 Long-Term 
Plan and the 2005 Equity Plan, as approved by Plexus’ shareholders.  The Committee believed that it was 
important to maintain its executive officers’ focus on performance for the Company’s shareholders even in 
the  event  of  a  potential  change  in  control.    Therefore,  offering  a  generous  package,  but  one  that  was 
consistent with market practices, was appropriate to help motivate executives to focus on the Company’s 
shareholders,  even  when  the  circumstance  might  jeopardize  their  employment.    The  Committee  also 
intended that the potential expense of the agreements be reasonable as compared to total enterprise value; 

30

the Committee estimated that the agreements represented approximately 3.0% of the average of fiscal 2007 
and fiscal 2006 total enterprise value at the time they were adopted.  Though the agreements were revised, 
the Committee did retain a “double trigger” so that the benefits would only be paid to the executive officers 
in the event of a substantial impact upon their employment and compensation. 

In  fiscal  2008,  the  Committee  also  approved  new  guidelines  to  determine  which  employees  should  have 
change in control agreements.  These new guidelines focus on position, classification code, responsibilities 
and compensation level in order to minimize subjectivity. 

The Committee periodically reviews the scope and context of the change in control agreements, as it did in 
2008.  The  Committee  continues  to  believe  that  the  change  in  control  agreements  will  help  motivate  the 
executive officers to respond appropriately, for the benefit of the Company and its shareholders, in the case 
of a proposed acquisition of the Company which they might perceive would jeopardize their employment.  

Tax Aspects of Executive Compensation

The Committee generally attempts to preserve the tax deductibility under the Internal Revenue Code (the 
“Code”)  of  all  executive  compensation.    However,  at  times  and  under  certain  circumstances,  it  believes  that  it  is 
more important to provide appropriate incentives irrespective of tax consequences.

Section  162(m)  of  the  Code  generally  limits  the  corporate  tax  deduction  for  compensation  paid  to  the 
executive officers  that  is not “performance-based”  to  $1 million  annually  per  executive officer.   Plexus has  taken 
action  with  respect  to  the  provisions  of  Section  162(m)  so  that  compensation  income  relating  to  stock  options, 
SARs,  performance-based  restricted  stock  and  cash  bonuses  under  the  2008  Long-Term  Plan  (and  predecessor 
plans) is exempt.  Compensation under these shareholder approved plans which is performance-based is generally 
not subject to the $1 million limitation; however, the grant of restricted shares without performance goals would not 
be  considered  to  be  performance-based  and  therefore  would  be  subject  to  the  limit  along  with  cash  salaries  and 
bonuses.    As  a  result  of  the  shareholders’  approval  of  the  2008  Long-Term  Plan  (and  its  predecessor)  and  the 
Purchase Plans, the Committee believes that most compensation income under these plans (other than any awards in 
the future of restricted stock or RSUs without performance goals, as is the case for the time vested RSUs granted in 
fiscal 2008) would not be subject to the Code’s deduction limitation.  However, if such restricted stock awards are 
made  and/or  any  executive  earns  a  sufficiently  high  VICP  bonus,  the  covered  compensation  of  some  individuals 
could exceed $1 million and, in those cases, the excess would not be tax deductible.  In some years, including fiscal 
2008,  the  Company  has  foregone  a  portion  of  its  tax  deduction  as  a  result  of  the  size  of  a  high  VICP  bonus.  
Although  the  Company  has  considered  strategies  for  dealing  with  these  tax  consequences  in  the  future,  the 
Committee has determined that the mix of compensation that it has used is nonetheless beneficial to achieving the 
Company’s goals. 

Other  provisions  of  the  Code  also  can  affect  the  decisions  which  we  make.    Section  280G  of  the  Code 
imposes  a  20%  excise  tax  upon  executive  officers  who  receive  “excess”  payments  upon  a  change  in  control  of  a 
publicly-held corporation to the extent the payments received by them exceed an amount approximating three times 
their  average  annual  compensation.    The  excise  tax  applies  to  all  payments  over  one  times  average  annual 
compensation.  Plexus would also lose its tax deduction for “excess” payments.  Our change in control agreements 
provide that benefits under them will be “grossed up” so that we also reimburse the executive officer for these tax 
consequences.  Although these gross up provisions and loss of deductibility would increase Plexus’ tax expense, the 
Committee  believes  it  is  important  that  the  effects  of  this  Code  provision  not  negate  the  protections  which  it 
provides by means of the agreements. 

The  Code  was  amended  to  provide  a  surtax  under  Section  409A,  relating  to  various  features  of  deferred 
compensation  arrangements  of  publicly-held  corporations  for  compensation  deferred  after  December  31,  2004.  
Section 409A becomes fully effective on January 1, 2009.  We have conducted an extensive review of our benefit 
plans and employment arrangements to help assure they comply with Section 409A and that there are no adverse 
effects on Plexus or our executive officers as a result of these Code amendments.  We have made various changes to 
some of these plans and arrangements, including Mr. Foate’s employment agreement, to ensure full compliance with 
the  new  rules  under  Section  409A;  however,  we  do  not  expect  these  changes  to  have  a  material  tax  or  financial 
consequence on Plexus.

(1)  Includes amounts voluntarily deferred by the named persons under the Plexus Corp. 401(k) Savings Plan (the 
“401(k)  Plan”)  and  the  Plexus  supplemental  executive  retirement  plan  (the  “SERP”).    The  amounts  deferred 
under  the  SERP  are  also  included  in  the  “Executive  Contributions  in  Last  FY”  column  of  the  “Nonqualified 
Deferred Compensation” table below. 

(2)  Both  the  “Bonus”  and  the  “Non-Equity  Incentive  Plan  Compensation”  columns  represent  amounts  that  were 
earned  during  fiscal  2008  and  fiscal  2007,  respectively,  under  our  Variable  Incentive  Compensation  Plan 
(“VICP”).    Under  the  VICP,  annual  bonuses  for  executive  officers  are  determined  by  a  combination  of  the 
degree to which Plexus achieves specific pre-set corporate financial goals during the fiscal year and individual 
objectives.  To the extent a payment was based on individual objectives, it is in the “Bonus” column.  To the 
extent that the bonus resulted from corporate financial performance, that portion of the bonus is included under 
the “Non-Equity Incentive Plan Compensation” column.  We include more information about the VICP under 
“Grants of Plan-Based Awards” below.  The amounts shown in the “2008” row were earned in fiscal 2008 but 
will be paid in fiscal 2009 and the amounts shown in the “2007” row were earned in fiscal 2007 and were paid 
in 2008. 

(3)  This column represents the value of stock and option awards granted under the 2008 Long-Term Plan and the 
2005  Equity  Plan,  which  are  explained  further  below  under  “Grants  of  Plan-Based  Awards.”    The  amounts 
shown represent the amounts expensed in fiscal 2008 and fiscal 2007 for grants and awards made in those and 
prior  years.    SFAS  123(R)  requires  us  to  recognize  compensation  expense  for  stock  options  and  other 
stock-related  awards  granted  to  our  employees  and  directors  based  on  the  estimated  fair  value  of  the  equity 
instrument  at  the  time  of  grant.    Compensation  expense  is  recognized  over  the  vesting  period.    The

requirements of SFAS 123(R) became effective for Plexus beginning in the first quarter of fiscal 2006.  The 
assumptions  which  we  used  to  determine  the  valuation  of  the  awards  are  discussed  in  footnote  11  to  our 
consolidated financial statements.  Please also see the “Grants of Plan-Based Awards” table below for further 
information about the options granted in fiscal 2008, and the “Outstanding Equity Awards at Fiscal Year End” 
table below relating to all outstanding option awards at the end of fiscal 2008. 

(4)  The  amounts  listed  under  the  column  entitled  “All  Other  Compensation”  in  the  table  include  Company 
contributions to the 401(k) Plan and the SERP (for Mr. Lim, this represents the Company’s contribution to the 
Malaysian Employees Provident Fund), reimbursement made by Plexus under its executive flexible perquisite 
benefit, the value of the company car provided to the executive, relocation expenses (including a gross-up for 
income  taxes)  related  to  a  move  to  Plexus’  Neenah  headquarters,  and  additional  life  and  disability  insurance 
coverage for Mr. Foate and Mr. Lim.  Per person detail is listed in the table below:

Mr. Foate 

Ms. Jones 

Mr. Verstegen 

Mr. Ninivaggi 

Mr. Lim 

As  a  matter  of  policy,  Plexus  avoids  providing  perquisites  beyond  a  company  car  to  its  executive  officers.  
However,  under  the  executive  flexible  perquisite  benefit,  most  executive  officers  may  be  reimbursed  for 
expenses  up  to  $10,000  (plus  a  gross  up  for  taxes)  in  a  calendar  year  for  miscellaneous  expenses  such  as 
personal  financial  planning,  spouse  travel  costs  in  connection  with  business-related  travel,  club  memberships 
and/or  tax  and  estate  advice.    The  amounts  in  this  column  include  the  reimbursements  under  that  program  in 
fiscal  2008,  including  the  related  tax  gross-up  amounts;  these  amounts  may  exceed  $10,000  due  to  the  tax 
gross-up and the difference between the fiscal and calendar year.

(5)  Ms.  Jones  joined  Plexus  on  April 9,  2007,  became  an  executive  officer  on  May 10,  2007,  and  was  named 
Plexus’ Chief Financial Officer on August 29, 2007.  The amounts listed in the “2007” row of the “Summary 
Compensation Table” above include all compensation paid by Plexus to Ms. Jones in the fiscal 2007, including 
amounts paid when she was not an executive officer. 

(6)  Mr. Lim was designated an executive officer on August 29, 2007.  The amounts listed in the “2007” row of the 
“Summary  Compensation  Table”  above  include  all  compensation  paid  by  Plexus  to  Mr.  Lim  in  fiscal  2007, 
including amounts paid when he was not an executive officer.

GRANTS OF PLAN-BASED AWARDS 
2008 

The following table sets forth information about stock and option awards which were granted to the named 
executive officers in fiscal 2008 under the 2008 Long-Term Plan and the 2005 Equity Plan, as well as information 
about the potential cash bonus awards dependent on quantifiable corporate performance goals which those executive 
officers could earn for fiscal 2008 performance (to be paid in fiscal 2009) under the VICP.  As a result of fiscal 2008 
corporate  performance,  bonuses  based  on  these  criteria  were  earned  in  2008,  as  set  forth  under  the  “Non-Equity 
Incentive Compensation” column in the “Summary Compensation Table” above.  We provide further information 
about both potential compensation under the VICP and awards under the 2008 Long-Term Plan and the 2005 Equity 
Plan in fiscal 2008 in the table below, and additional information about those plans below the table.

*  Represents a potential bonus payment for fiscal 2008 at various performance levels under the VICP to the extent 
they would result from corporate performance; other grants are stock options under the 2005 Equity Plan and the 
2008  Long-Term  Plan.    Based  on  Plexus’  actual  performance  in  fiscal  2008,  bonuses  were  earned  based  on 
corporate  financial  performance;  those  amounts  are  shown  in  the  “Summary  Compensation  Table”  and  were 
between the target and maximum amounts. 

(1) Amounts  in  the  row  labeled  “VICP*”  reflect  potential  bonus  payments  which  would  depend  upon  Plexus 
meeting corporate financial goals; these exclude potential bonus amounts for individual objectives.  The amount 
in the “Threshold” column indicates a payment for performance just above the threshold; there is no minimum 
payment once the threshold has been exceeded.  The amounts in the “Target” column of the row labeled “RSUs 
& long-term cash” represent long-term cash awards, which accompany grants of RSUs to offset taxes due on the 
vesting of RSUs in order to encourage retention of the shares received, as well as to round out the compensation 
package. 

(2) Options were granted  at  the average  of  the  high  and  low  trading  prices  on  the date  of  grant.    Under  the  2005 
Equity  Plan,  fair  market  value  was  determined  either  as  the  closing  price  or  the  average  of  the  high  and  low 
trading prices, either on the date of grant or as an average for a short period of time prior to the grant.  Under the 
2008 Long-Term Plan, fair market value may be determined as the average of the high and low trading prices on 
the date of grant or as an average for a short period of time prior to the grant.  The stock options which were 
granted  in  fiscal  2008  under  both  the  2005  Equity  Plan  and  the  2008  Long-Term  Plan  vest  over  a  two  year 
period, with 50% of the options vesting on the first anniversary of their grant date and the remainder vesting on 
the second anniversary.  

(3) The RSUs vest on November 5, 2010, assuming continued employment.  Grants of RSUs were accompanied by 
long-term cash awards, which vest on the same schedule and according to the same circumstances as the RSUs.  
Long-term cash awards were granted to help offset the taxes due upon the vesting of RSUs in order to encourage 
retention of the shares received, as well as to round out the compensation package.  See the discussions below 
under the captions “2008 Long-Term Plan” and “2005 Equity Plan.”  

VICP

Under the VICP, our executive officers may earn bonuses which depend in substantial part upon the degree 
to which Plexus achieves corporate financial goals which are set by our Compensation and Leadership Development 
Committee shortly after the beginning of our fiscal year.  Each executive officer also may earn a portion of his or 
her bonus by achieving individual objectives set for that executive officer.  The amounts included in the table are 
potential  future  payouts  under  non-equity  incentive  awards  which  could  be  earned  pursuant  to  the  corporate 
financial  goals  under  the VICP.    The amounts  in  the  columns  represent,  respectively,  the  amount  which  could be 
earned in the event minimum results were achieved so as to result in a threshold payment to the executive officer, 
the  amounts  which  could  be  received  if  each  performance  target  was  exactly  met  at  the  targeted  level,  and  the 
maximum amount which could be earned under the VICP.  Actual corporate performance was between the target 
and maximum levels on sales and exceeded the target level on ROCE, so amounts were paid accordingly between 
target  and  maximum,  as  reported  in  the  “Non-Equity  Incentive  Compensation”  column  in  the  “Summary 
Compensation Table” above. 

In addition, a portion of each individuals’ award could be earned based on individual objectives applicable 
specifically  to  that  individual.    These  awards  are  intended  to  reflect  in  each  instance  an  individual’s  performance 
which may not be reflected in financial performance for the entire company.  The maximum amount that could be 
earned based on individual performance was $134,596 for Mr. Foate (which would have been 20% of his bonus at 
the  targeted  levels)  and  varied  from  $16,018  to $30,197  for  the other  named  executive  officers (also representing 
20%).    The  actual  amounts  earned  by  these  persons  are  included  above  in  the  “Bonus”  column  in  the  “Summary 
Compensation Table.” 

2008 Long-Term Plan

Under the 2008 Long-Term Plan, the Compensation and Leadership Development Committee of the board 
of directors may grant directors, executive officers and other officers and key employees of Plexus stock options, 
stock-settled  SARs,  restricted  stock,  which  may  be  designated  as  restricted  stock  awards  or  RSUs,  performance 

36

stock awards (which may be settled in cash or stock), and cash bonus awards in periodic grants.  In fiscal 2007, as a 
result of the volatility of the stock market, particularly for Plexus stock, the Committee began the practice of making 
quarterly option grants.  This facilitates overall compensation planning near the beginning of the fiscal year, as the 
total target amounts for grants for a year are set at that time.  The Committee continues to make quarterly option 
grants; the specific dates of each grant are determined in advance.  Option grants must be at the fair market value of 
the underlying shares when the grant is made. 

Beginning in fiscal 2008, the Committee granted RSUs under the predecessor to the 2008 Long-Term Plan.  
In 2008, the grants were made at the beginning of the fiscal year and vest three years from the date of the grant, 
assuming  continued  employment;  the  Committee  anticipates  continuing  this  practice.    The  grants  of  RSUs  were 
accompanied by long-term cash awards, which are intended to defray tax effects to the grantees upon vesting of the 
RSUs as an incentive to those persons to continue to hold their shares upon vesting because they will not need to sell 
shares to raise cash to pay taxes; we also use long-term cash awards to round out the compensation package.  Long-
term cash awards will vest on the same schedule and under the same circumstances as grants of RSUs.

2005 Equity Plan

Previously, under the 2005 Equity Plan, the Compensation and Leadership Development Committee of the 
board of directors granted directors, executive officers and other officers and key employees of Plexus stock options, 
SARs,  RSUs  and/or  shares  of  restricted  stock  in  periodic grants.    Through  the  end  of fiscal  2007,  the  Committee 
only granted stock options under the 2005 Equity Plan.  The Committee began to grant RSUs and SARs in fiscal 
2008; grants of RSUs were accompanied by long-term cash awards, which vest on the same schedule and under the 
same  circumstances  as  RSUs.    Through fiscal  2006,  the Committee  made  annual  grants  of options  approximately 
one  week  after  the  May  board  meeting,  on  a  date  set  in  advance  to  help  avoid  the  possibility  of  market  timing. 
Option grants were at the fair market value of the underlying shares when the grant was made.

The 2005 Equity Plan was replaced by the 2008 Long-Term Plan, upon its approval by shareholders at the 
2008  annual  meeting  of  shareholders.    No  further  grants  are  being  made  under  the  2005  Equity  Plan  except,  in 
certain  circumstances,  to  employees  in  the  United  Kingdom.    Any  such  grants  are  subtracted  from  the  shares 
available for issuance under the 2008 Long-Term Plan.

 (1)  Option award, under the 2008 Long-Term Plan or its predecessor plan.  All options have an exercise price equal 
to  the  market  price  of  our  common  stock  on  the  date  of  grant.    Since  2005,  the  market  price  has  been 
determined using the average of the high and low trading prices on the grant date.  Prior to that date, the market 
price was determined by an average of the high and low trading prices over a period of five to ten trading days 
prior to the grant date.  Options granted in fiscal 2005 vested immediately.  Options granted in fiscal 2006 vest 
one-third  on  each  of  the  first  three  anniversaries  of  the  grant  date.    Options  granted  in  fiscal  2007  and  fiscal 
2008 vest one-half on each of the first two anniversaries of the grant date. 

(2)  Consists of RSUs awarded in fiscal 2008 under the 2005 Equity Plan. The RSUs vest on November 5, 2010,

NONQUALIFIED DEFERRED COMPENSATION 
2008 

Plexus  does  not  maintain  any  defined  benefit  pension  plans.    Plexus’  only  retirement  savings  plans  are 
defined contribution plans: the 401(k) Savings Plan (the “401(k) Plan”) for all qualifying U.S. employees; and the 
supplemental  executive  retirement  plan  (the  “SERP”)  for  designated  executive  officers  and  certain  other  key 
employees.  Because these are defined contribution plans, Plexus’ obligations are fixed at the time contributions are 
made, rather than Plexus being liable for future potential shortfalls in plan assets to cover the fixed benefits that are 
promised in defined benefit plans.

The 401(k) Plan is open to all U.S. Plexus employees meeting specified service and related requirements.  
Under the plan, employees may voluntarily contribute up to 50% of their annual compensation, up to a maximum 
tax code mandated limit of $15,500; Plexus will match 100% of the first 2.5% of salary which an employee defers, 
up to $5,750 in calendar year 2008.  There are several investment options available to participants under the 401(k) 
Plan, including a Plexus stock fund. 

Plexus maintains the SERP as an additional deferred compensation mechanism for most executive officers; 
the individuals covered in fiscal 2008 include Ms. Jones and Messrs. Foate, Verstegen and Ninivaggi.  Mr. Lim does 
not participate because he is not a United States resident.  Under the SERP, a covered executive may elect to defer 
some  or  all  of  his  or  her  compensation  through  the  plan,  and  Plexus  may  credit  the  participant’s  account  with  a 
discretionary employer contribution.  Participants are entitled to the payment of deferred amounts and any earnings 
which  may  be  credited  thereon  upon  termination  or  retirement  from  Plexus,  subject  to  the  participants’  deferral 
elections and Section 409A of the Code.  The rabbi trust arrangement established under the SERP allows investment 
of deferred compensation held on behalf of the participants into individual accounts and, within these accounts, into 
one or more designated mutual funds or investments.  These investment choices do not include Plexus stock. 

Executive  officers’  personal  voluntary  deferrals  to  the  SERP  for  fiscal  year  2008  totaled  $222,542, 
including  those  by  the  named  executive  officers  as  set  forth  in  the  table  below.    In  addition,  the  plan  allows  for 
discretionary Plexus contributions.  Since fiscal 2006, discretionary contributions have been the greater of (a) 7% of 
the  executive’s  total  targeted  cash  compensation,  minus  Plexus’  permitted  contributions  to  the  executive  officer’s 
account  in  the  401(k)  Plan,  or  (b)  $13,500.    The  Committee  may  also  choose  to  make  additional  or  special 
contributions; none were  made  in fiscal  2008 other  than a  special  contribution of $265,500  to  a  former  executive 
officer of Plexus upon his permanent leave in recognition of his prior service and contributions to the Company. 

40

 
Mr.  Lim  does  not  participate  in  these  plans  because  he  is  a  resident  of  Malaysia  and  is  covered  by  a 
different system.  Under Malaysian law, an employer must make a contribution to the fund of at least 12% of every 
employee’s  salary  during  the  year  to  the  Employees  Provident  Fund,  which  is  a  retirement  savings  program 
established under Malaysian law.  In accordance with its practice in Malaysia, Plexus made a contribution of 17% 
for Mr. Lim to reflect his seniority and responsibilities. 

The following table includes information as to contributions under the SERP or, in the case of Mr. Lim, the 
Malaysian  Employees  Provident  Fund.    Since  the  401(k)  Plan  is  a  tax-qualified  plan  generally  available  to  all 
employees, contributions on behalf of the executive officers and earnings in that plan are not included in this table; 
however, company contributions under both are among the items included in the “All Other Compensation” column 
in the “Summary Compensation Table” above.

EMPLOYMENT AGREEMENTS AND POTENTIAL PAYMENTS UPON TERMINATION OR 
CHANGE IN CONTROL 

In this section, we are providing information about specific agreements with our executive officers relating 
to  employment  and  their  post-employment  compensation.    As  discussed  further  below,  only  Mr.  Foate  has  an 
employment  agreement.    All  of  our  executive  officers  have  change  in  control  agreements  which  will  provide,  in 
certain circumstances, for payments to the executive officers in the event of a change in control of Plexus. 

Mr. Foate’s Employment Agreement

Plexus does not generally have employment agreements with its executive officers.  However, when Mr. 
Foate became Plexus’ Chief Executive Officer in 2002, the Compensation and Leadership Development Committee 
and the board believed it was important to enter into an employment agreement with Mr. Foate to set forth the terms 
of his  employment  and  to  provide  incentives  for  him  to  continue  with  the  Company  over  the  long  term.    In  May 
2008, the Company entered into a new employment agreement with Mr. Foate.  The new employment agreement, 
which  was  approved  by  the  Compensation  and  Leadership  Development  Committee  and  the  board,  amended  and 
superseded Mr. Foate’s previous employment agreement with the Company.  Changes were made in order to more 

41

fully comply with changes made to Internal Revenue Code (the “Code”) Section 409A and to integrate the change in 
control  provisions  into  the  employment  agreement;  however,  the  benefits  payable  under  the  new  agreement  are 
substantially unchanged from those under the previous agreements. 

Mr.  Foate’s  new  employment  agreement  is  for  an  initial  term  of  three  years  and  automatically  extends 
(unless terminated) by one year every year, so that it maintains a rolling three-year term.  The agreement specifies 
when Plexus may terminate Mr. Foate for cause, or when Mr. Foate may leave the Company for good reason, and 
determines  the  compensation  payable  upon  termination.    The  definition  of  “cause”  and  “good  reason”  are 
substantially similar to those under the change in control agreements, as described below, although “good reason” 
would also include a failure of Plexus to renew the employment agreement.  If Mr. Foate is terminated for cause or 
voluntarily  leaves  without  good  reason, dies  or  becomes  disabled,  or  the  agreement  is  not  renewed, Plexus  is  not 
required to make any further payments to  Mr. Foate other than with respect to obligations accrued on the date of 
termination.  If Plexus terminates Mr. Foate without cause, or he resigns with good reason, Mr. Foate is entitled to 
receive  compensation  including  his  base  salary  for  a  three  year  period  following  his  separation  date,  a  pro-rated 
VICP bonus keyed to the actual attainment of performance targets for the year in which Mr. Foate is involuntarily 
terminated, and certain lump sum payments designed to ensure that his benefits approximate those provided under 
the previous employment agreement.  The lump sum payments are equal to the sum of one hundred percent (100%) 
of Mr. Foate’s annual base salary prior to his separation date and the maximum amount of Company contributions 
for a full plan year under the 401(k) Plan and the Company’s deferred compensation plans.  Mr. Foate would also be 
eligible to participate in the Company’s medical, dental and vision plans, subject to his payment of any premiums 
required by such plans, for a three year period following his separation from Plexus.  Any payments triggered by a 
termination of employment are to be delayed until six months after termination, as required by Section 409A of the 
Code. 

Mr. Foate was previously covered by a separate change in control agreement with Plexus; however, change 
in  control  provisions  were  incorporated  into  Mr.  Foate’s  new  employment  agreement  and  the  previous  change  in 
control agreement with Plexus was terminated.  The change in control provisions are substantially identical to those 
provided in the change in control agreements described below under the caption “Change in Control Agreements,” 
with Mr. Foate’s payment amount being three times the relevant salary plus benefits. 

Under Mr. Foate’s employment agreement, Plexus is also protected from competition by Mr. Foate after his 
employment with Plexus would cease.  Upon termination, Mr. Foate agrees to not interfere with the relationships 
between the customers, suppliers or employees of Plexus for two years, and that he will not compete with Plexus 
over the same period and in geographical locations proximate to Plexus’ operations.  Further, Mr. Foate has agreed 
to related confidentiality requirements after the termination of his employment. 

Under  the  2008  Long-Term  Plan  and  predecessor  plans,  optionholders  (or  their  representatives)  have  a 
period of time in which they may exercise vested stock options after death, disability, retirement or other termination 
of  employment,  except  in  the  case  of  termination  with  cause.    Options  do  not  continue  to  vest  after  termination 
except  for  full  vesting  upon  a  change  in  control  or,  when  provided  in  related  option  agreements,  upon  death  or 
disability.    See  “Outstanding  Equity  Awards  at  Fiscal  Year  End”  above  for  information  as  to  Mr.  Foate’s 
outstanding stock options at September 27, 2008.  Mr. Foate would also receive accrued and vested benefits under 
the 401(k) Plan and the SERP, and payment for accrued but unused vacation, upon a termination of employment for 
any  reason;  those  amounts  are  not  included  in  “Potential  Benefits  Table”  below.    See  “Nonqualified  Deferred 
Compensation” above for further information. 

Change in Control Agreements

In May 2008, the board approved a new form of change in control agreement.  Apart from changes required 
by  Section  409A  of  the  Code,  including  delaying  payment  triggered  by  a  termination  of  employment  until  six 
months after the termination if the employee is among the Company’s 50 top-paid employees, and changing certain 
definitions  to  be  consistent  with  Section  409A,  the  new  change  in  control  agreements  do  not  contain  any  other 
material changes from the previous change in control agreements.  Additionally, the benefits payable under the new 
change in control agreements are the same in all material economic respects to the benefits provided by the previous 
change in control agreements. 

42

Plexus has change in control agreements with Ms. Jones and Messrs. Verstegen, Ninivaggi and Lim, and its 
other  executive  officers  (with  the  exception  of  Mr.  Foate  as  described  above  under  the  caption  “Mr.  Foate’s 
Employment  Agreement”)  and  certain  other  key  employees.    Under  the  terms  of  these  agreements,  if  there  is  a 
change  in  control  of  Plexus,  as  defined  in  the  agreement,  the  executive  officers’  authorities,  duties  and 
responsibilities shall remain at least commensurate in all material respects with those prior to the change in control.  
Their  compensation  may  not  be  reduced.    Their  benefits  must  be  commensurate  with  those  of  similarly  situated 
executives of the acquiring firm, and their location of employment must not be changed significantly as a result of 
the change in control. 

Within 24 months after a change in control, in the event that any covered executive officer is terminated 
other than for cause, death or disability, or an executive officer terminates his or her employment with good reason, 
Plexus is obligated to pay the executive officer, in a cash lump sum, an amount equal to either two or three times 
(from one to two times for other key employees) the executive officer’s base salary plus targeted bonus payment, 
and to continue retirement payments and certain other benefits.  The change in control agreements designate three 
times salary plus benefits for each of Ms. Jones and Messrs. Verstegen, Ninivaggi and Lim.  The agreements further 
provide for payment of additional amounts which may be necessary to “gross up” the amounts due to such executive 
officer  in  the  event  of  the  imposition  of  an  excise  tax  upon  the  payments.    The  agreements  do  not  preclude 
termination of the executive officer, or require payment of any benefit, if there has not been a change in control of 
Plexus, nor do they limit the ability of Plexus to terminate these persons thereafter for cause. 

Under our change in control agreements: 

(cid:2)

(cid:2)

(cid:2)

A termination for a “cause” would occur if the executive officer willfully and continually fails to 
perform  substantial  duties  or  willfully  engages  in  illegal  conduct  or  gross  misconduct  which 
injures Plexus. 

After  a  change  in  control,  an  executive  may  terminate  for  “good  reason”  which  would  include: 
requiring  the  executive  to  perform  duties  inconsistent  with  the  duties  provided  under  his  or  her 
agreement;  Plexus  not  complying  with  provisions  of  the  agreement;  the  Company  requiring  the 
executive  to  move;  or  any  attempted  termination  of  employment  which  is  not  permitted  by  the 
agreement. 

A  change  in  control  would  occur  in  the  event  of  a  successful  tender  offer  for  Plexus,  other 
specified  acquisitions  of  a  substantial  portion  of  the  Company’s  outstanding  stock,  a  merger  or 
other business combination involving the Company, a sale of substantial assets of the Company, a 
contested  director’s  election  or  a  combination  of  these  actions  followed  by  any  or  all  of  the 
following  actions:  change  in  management  or  a  majority  of  the  board  of  the  Company  or  a 
declaration of a “change in control” by the board of directors. 

Also, under the 2008 Long-Term Plan and predecessor plans, award holders (or their representatives) have 
a period of time in which they may exercise vested awards after death, disability, retirement or other termination of 
employment, except in the case of termination with cause.  Awards do not continue to vest after termination, except 
for full vesting upon death or permanent disability when provided in the related award agreements or upon a change 
in  control.    See  “Outstanding  Equity  Awards  at  Fiscal  Year  End”  above  for  information  as  to  executive  officers’ 
outstanding stock options at September 27, 2008 (the named executive officers do not hold any stock-settled SARs).  
Executives would also receive accrued and vested benefits under the 401(k) Plan and the SERP, and payment for 
accrued but unused vacation, upon a termination of employment for any reason; those amounts are not included in 
the table.  See “Nonqualified Deferred Compensation” above for further information. 

Plexus does not have employment agreements with its executive officers other than Mr. Foate.  It also does 
not  have  a  formal  severance  plan  for  other  types  of  employment  termination,  except  in  the  event  of  a  change  in 
control as described above.  Although Plexus has a general practice of providing U.S. salaried employees with two 
weeks’  severance  pay  for  every  year  worked  in  the  case  of  termination  without  cause,  actual  determinations  are 
made on a case-by-case basis.  Therefore, whether and to what extent Plexus would provide severance benefits to 
the  named  executive  officers,  or  other  executive  officers,  upon  termination  (other  than  due  to  death,  permanent 
disability  or  a  change  in  control)  would  depend  upon  the  facts  and  circumstances  at  that  time.    As  such,  we  are 
unable to estimate the potential payouts under other employment termination scenarios.

Potential Benefits Table

The following table provides information as to the amounts which will be payable (a) to Mr. Foate under 
his  employment  agreement  if  he  is  terminated  by  Plexus  for  cause  or  without  cause,  (b) to  the  named  executive 
officers in the event of death or permanent disability, and (c) to the named executive officers in the event they were 
terminated without cause, or the executive terminated with good reason, in the event of a change in control.  The 
payments are calculated assuming a termination as of September 27, 2008, the last day of our previous fiscal year.  
The table includes only benefits that would result from death or permanent disability, a termination or a change in 
control, not vested benefits that are payable irrespective of a change.

(1) This  amount  represents  payments  relating  to  the  executives’  base  salary  and  VICP  bonus  to  the  extent  they 
would be paid after termination, based on the salary in effect at the end of fiscal 2008 and the target VICP bonus 
for 2008.  Under the change in control agreements, this payment equals three years salary, as it was in effect at 
the time of termination, plus three times the targeted VICP compensation for the year of termination.  There are 
similar provisions for a termination without cause in Mr. Foate’s employment agreement. 

(2) All outstanding unvested stock options would become vested upon a change in control, and the unvested options 
also would vest upon death or disability.  The amount shown represents the difference in value of the unvested 
options between their exercise price and market price, based on Plexus’ closing stock price of $21.70 per share

(3) All outstanding RSUs and long-term cash awards would become vested upon a change in control.  The amount 
shown represents the difference in value of the unvested RSUs and long-term cash awards between their grant 
price and market price, based on Plexus’ closing stock price of $21.70 per share on September 26, 2008, the last 
trading day of fiscal 2008. 

(4) Under  the  change  in  control  agreements,  the  Company  would  be  required  to  continue  payments  to  the  401(k) 
Plan  and  SERP  for  three  years  at  the  same  level  during  the  year  preceding  the  change  in  control.    There  are 
similar  provisions  for  a  termination  without  cause  in  Mr.  Foate’s  employment  agreement.    This  column 
represents  the total  amount  of  those  payments.    The  executive  officers would  also  receive  accrued  and vested 
benefits under the 401(k) Plan and the SERP, and payment for accrued but unused vacation, upon a termination 
of  employment  for  any  reason;  those  amounts  are  not  included  in  the  table.    See  “Nonqualified  Deferred 
Compensation” for further information. 

(5) These  amounts  include  continuing  payments  of  health  and  welfare  benefits,  accrued  vacation,  executive 
reimbursement plan expenses, company car and other benefits for three years, as provided in the agreement. 

(6) In  the  event  of  a  change  in  control  in  Plexus,  the  change  in  control  agreements  with  our  executive  officers 
provide that we will pay them an additional benefit to reimburse the “golden parachute” excise taxes which they 
would  owe  pursuant  to  Internal  Revenue  Code  Section 280G.    This  column  provides  an  estimate  of  these 
payments, reflecting each executive’s base compensation under Section 280G. 

(7) Excludes life or disability insurance payments from third party insurers. 

CERTAIN TRANSACTIONS

Plexus  has  a  written  policy  requiring  that  transactions,  if  any,  between  Plexus  on  the  one  hand  and  its 
executive officers, directors or employees (or related parties) on the other hand must be on a basis that is fair and 
reasonable to the Company and in accordance with Plexus’ Code of Conduct and Business Ethics and other policies.  
Plexus’  policy  focuses  on  related  party  transactions  in  which  its  insiders  or  their  families  have  a  significant 
economic interest; while the policy requires disclosure of all transactions, it recognizes that there may be situations 
where Plexus has ordinary business dealings with other large companies in which insiders may have some role but 
little  if  any  stake  in  a  particular  transaction.    Although  these  transactions  are  not  prohibited,  any  such  transaction 
must be approved by either a disinterested majority of the board of directors or by the Audit Committee.   

Please  see  “Corporate  Governance-Director  Independence”  for  certain  transactions  and  relationships 
between Plexus and two directors which the board considered when determining the independence of the directors.  
There were no other transactions in an amount or of a nature which were reportable under applicable SEC rules in 
fiscal 2008. 

REPORT OF THE AUDIT COMMITTEE 

The  Audit  Committee  of 

the  board  of  directors,  which  was  established  in  accordance  with 
Section 3(a)(58)(A) of the Securities Exchange Act, oversees and monitors the participation of Plexus’ management 
and  independent  auditors  throughout  the  financial  reporting  process  and  approves  the  hiring  and  retention  of  and 
fees paid to the independent auditors.  The Audit Committee also generally reviews other transactions between the 
Company  and  interested  parties  which  may  involve  a  potential  conflict  of  interest.    No  member  of  the  Audit 
Committee  is  employed  or  has  any  other  material  relationship  with  Plexus.    The  members  are  “independent 
directors”  as  defined  in  Rule  4200(a)(15)  of  the  NASD  listing  standards  applicable  to  the  Nasdaq  Global  Select 
Stock  Market  and  relevant  SEC  rules.    The  Plexus  board  of  directors  has  adopted  a  written  charter  for  the  Audit 
Committee, and the current version is available on Plexus’ website. 

45

In  connection  with  its  function  to  oversee  and  monitor  the  financial  reporting  process  of  Plexus  and  in 
addition  to  its  quarterly  review  of  interim  unaudited  financial  statements,  the  Audit  Committee  has  done  the 
following: 

(cid:129) 

(cid:129) 

(cid:129) 

reviewed  and  discussed  the  audited  financial  statements  for  the  fiscal  year  ended  September 27, 
2008 with Plexus management; 
discussed  with  PricewaterhouseCoopers  LLP,  Plexus’  independent  auditors,  those  matters which 
are    required  to  be  discussed  by  Statement  on  Auditing  Standards  No.  114,  “The  Auditor’s 
Communication  with  Those  Charged  with  Governance”  and  SEC  Regulation  S-X,  Rule  2-07 
“Communication with Audit Committees”; and 
received the written disclosure and the letter from PricewaterhouseCoopers LLP required by the 
applicable  standards  of  the  Public  Company  Accounting  Oversight  Board  regarding  the 
independent  accountant's  communications  with  the  Audit  Committee  concerning  independence, 
and has discussed with PricewaterhouseCoopers LLP its independence. 

Based  on  the  foregoing,  the  Audit  Committee  recommended  to  the  board  of  directors  that  the  audited 
financial  statements  be  included  in  Plexus’  annual  report  on  Form  10-K  for  the  fiscal  year  ended  September 27, 
2008.  The Audit Committee further confirmed the independence of PricewaterhouseCoopers LLP. 

Members of the Audit Committee:  David J. Drury, Chair 

Peter Kelly 

AUDITORS 

Stephen P. Cortinovis 
Mary A. Winston

Subject  to  ratification  by  shareholders,  the  Audit  Committee  intends  to  reappoint  the  firm  of 
PricewaterhouseCoopers  LLP  as  independent  auditors  to  audit  the  financial  statements  of  Plexus  for  fiscal  2009.  
Representatives of PricewaterhouseCoopers LLP are expected to be present at the annual meeting of shareholders to 
respond to questions and make a statement if they desire to do so. 

Fees and Services 

Fees  (including  reimbursements  for  out-of-pocket  expenses)  paid  to  PricewaterhouseCoopers  LLP  for 

services in fiscal 2008 and 2007 were as follows:   

Audit fees: 
Audit-related fees: 
Tax fees: 
All other fees: 

     2008  

   2007

$1,056,000 
        -- 
       44,100 
         --   

$1,057,200 
         --   
       30,000 
        -- 

The above amounts relate to services provided in the indicated fiscal years, irrespective of when they were billed.  
Audit  fees  related  to  Plexus’  annual  audit  and  quarterly  professional  reviews;  audit  fees  also  included substantial
work related to the certification of Plexus’ internal controls as required by the Sarbanes-Oxley Act.  Tax services 
consisted  primarily  of  compliance  and  other  tax  advice  regarding  special  Plexus  projects.    The  Audit  Committee 
considered  the  compatibility  of  the  non-audit  services  provided  by  PricewaterhouseCoopers  LLP  with  the 
maintenance of that firm’s independence. 

The Audit Committee generally approves all engagements of the independent auditor in advance, including 
approval of the related fees.  The Audit Committee approves an annual budget (and may from time to time approve 
amendments thereto), which specifies projects and the approved levels of fees for each.  To the extent that items are 
not  covered  in  the  annual  budget  or  fees  exceed  the  budget,  management  must  have  such  items  approved  by  the 
Audit Committee or, if necessary between Audit Committee meetings, by the Audit Committee chairman on behalf 
of the Audit Committee.  There were no services in fiscal 2008 or 2007 which were not approved in advance by the 
Audit Committee under this policy.

PART 1

ITEM 1. 

BUSINESS 

Overview 

Plexus Corp. and its subsidiaries (together “Plexus,” the “Company,” or “we”) participate in the Electronic 

Manufacturing Services (“EMS”) industry.  We provide product realization services to original equipment manufacturers 
(“OEMs”) and other technology companies in the wireline/networking, wireless infrastructure, medical, 
industrial/commercial and defense/security/aerospace market sectors.  We provide advanced electronics design, 
manufacturing and testing services to our customers with a focus on the mid-to-lower-volume, higher-mix segment of 
the EMS market.  Our customers’ products typically require exceptional production and supply-chain flexibility, 
necessitating an optimized demand-pull-based manufacturing and supply chain solution across an integrated global 
platform.  Many of our customers’ products require complex configuration management and direct order fulfillment to 
their customers across the globe.  In such cases we provide global logistics management and after-market service and 
repair.   Our customers’ products may have stringent requirements for quality, reliability and regulatory compliance.  We 
offer our customers the ability to outsource all phases of product realization, including product specifications; 
development, design and design validation; regulatory compliance support; prototyping and new product introduction; 

1

 
manufacturing test equipment development; materials sourcing, procurement and supply-chain management; product 
assembly/manufacturing, configuration and test; order fulfillment, logistics and service/repair.   

Plexus is passionate about its goal to be the best EMS company in the world at providing services for customers 

that have mid-to-lower-volume requirements and a higher mix of products.  We have tailored our engineering services, 
manufacturing operations, supply-chain management, workforce, business intelligence systems, financial goals and 
metrics specifically to support these types of programs.  Our flexible manufacturing facilities and processes are designed 
to accommodate customers with multiple product-lines and configurations as well as unique quality and regulatory 
requirements.  Each of these customers is supported by a multi-disciplinary customer team and one or more uniquely 
configured “focus factories” supported by a supply-chain and logistics solution specifically designed to meet the 
flexibility and responsiveness required to support that customer’s fulfillment requirements.  

Our go-to-market strategy is also tailored to our target market sectors and business strategy.  We have business 
development and customer management teams that are dedicated to each of the five sectors we serve.  These teams are 
accountable for understanding the sector participants, technology, unique quality and regulatory requirements and 
longer-term trends.  Further, these teams help set our strategy for growth in their sectors with a particular focus on 
expanding the services and value-add that we provide to our current customers while strategically targeting select new 
customers to add to our portfolio. 

Our financial model is aligned with our business strategy, with our primary focus to earn a return on invested 

capital (“ROIC”) in excess of our weighted average cost of capital (“WACC”).  The smaller volumes, flexibility 
requirements and fulfillment needs of our customers typically result in greater investments in inventory than many of our 
competitors, particularly those that provide EMS services for high-volume, less complex products with less stringent 
requirements (such as consumer electronics).  In addition, our cost structure relative to these peers includes higher 
investments in selling and administrative costs as a percentage of sales to support our sector-based go-to-market strategy, 
smaller program sizes, flexibility, and complex quality and regulatory compliance requirements.  By exercising 
discipline to generate a ROIC in excess of our WACC, our goal is to ensure that Plexus creates a value proposition for 
our shareholders as well as our customers. 

Our customers include both industry-leading OEMs and other technology companies that have never 
manufactured products internally.  As a result of our focus on serving market sectors that rely on advanced electronics 
technology, our business is influenced by technological trends such as the level and rate of development of 
telecommunications infrastructure, the expansion of networks and use of the Internet.  In addition, the federal Food and 
Drug Administration’s approval of new medical devices, defense procurement practices and other governmental 
approval and regulatory processes can affect our business.  Our business has also benefited from the trend to increased 
outsourcing by OEMs.  

We provide most of our contract manufacturing services on a turnkey basis, which means that we procure 

some or all of the materials required for product assembly.  We provide some services on a consignment basis, which 
means that the customer supplies the necessary materials, and we provide the labor and other services required for 
product assembly.  Turnkey services require material procurement and warehousing, in addition to manufacturing, and 
involve greater resource investments than consignment services.  Other than certain test equipment and software used 
for internal operations, we do not design or manufacture our own proprietary products. 

Established in 1979 as a Wisconsin corporation, we have approximately 7,900 full-time employees, including 

approximately 1,300 engineers and technologists dedicated to product development and design, test equipment 
development and design, and manufacturing process development and control, all of whom operate from 19 active 
facilities in 14 locations, totaling approximately 2.6 million square feet.   

We maintain a website at www.plexus.com.  We make available through that website, free of charge, copies of 

our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Reports on Form 8-K, and amendments to those 
reports, as soon as reasonably practical after we electronically file those materials with, or furnish them to, the 
Securities and Exchange Commission (“SEC”).  Our Code of Conduct and Business Ethics is also posted on our 
website. You may access these SEC reports and the Code of Conduct and Business Ethics by following the links under 
“Investor Relations” at our website. 

Services

Plexus offers a broad range of integrated services as more fully described below; our customers may utilize 

any, or all, of the following services and tend to use more of these services as their outsourcing strategies mature: 

2

Product development and design.  We provide comprehensive conceptual design and value-engineering 

services. These product design services include project management, feasibility studies, product conceptualization, 
specification development for product features and functions, circuit design (including digital, microprocessor, power, 
analog, radio frequency (RF), optical and micro-electronics), field programmable gate array design (FPGA), printed 
circuit board layout, embedded software design, mechanical design (including thermal analysis, plastic components, 
sheet metal enclosures, and castings), development of test specifications and product validation testing. We invest in the 
latest design automation tools and technology.  We also provide comprehensive value-engineering services for our 
customers that extend the life cycles of their products.  These value-added services include engineering change-order 
management, cost reduction redesign, component obsolescence management, product feature expansion, test 
enhancement and component re-sourcing.   

Prototyping and new product introduction services.  We provide assembly of prototype products within our 
operating sites.  We supplement our prototype assembly services with other value-added services, including materials 
management, analysis of the manufacturability and testability of a design, test implementation and pilot production runs 
leading to volume production.  These services link our engineering and our customers’ engineering to our volume 
manufacturing facilities.  These links facilitate an efficient transition from engineering to manufacturing.  We believe 
that these services provide significant value to our customers by accelerating their products’ time-to-market schedule, 
reducing change activity and providing a robust product set. 

Test equipment development.  Enhanced product functionality has led to increasingly complex components and 

assembly techniques; consequently, there is a need to design and assemble increasingly complex in-circuit and 
functional test equipment for electronic products and assemblies.  Our internal development of this test equipment 
allows us to rapidly specify, implement, maintain and enhance test solutions that efficiently test printed circuit 
assemblies, subassemblies, system assemblies and finished products.  We also develop specialized equipment that 
allows us to environmentally stress-test products during functional testing to assure reliability.  We believe that the 
internal design and production of test equipment is an important factor in our ability to provide technology-driven 
products of consistently high quality. 

Material sourcing and procurement.  We provide contract manufacturing services on either a “turnkey” basis, 

which means we source and procure the materials required for product assembly, or on a “consignment” basis, which 
means the customer supplies the materials necessary for product assembly. Turnkey services include materials 
procurement and warehousing in addition to manufacturing and involve greater resource investment and potential 
inventory risk than consignment services.  Substantially all of our manufacturing services are currently on a turnkey 
basis.

Agile manufacturing services.   We have the manufacturing services expertise required to assemble very 
complex electronic products that utilize multiple printed circuit boards and subassemblies.  These manufacturing 
services, which we endeavor to provide on an agile and rapid basis, include developing and implementing materials and 
manufacturing strategies that meet our customers' requirements for demand flexibility, for assembling printed circuit 
boards utilizing a wide range of assembly technologies, and for building and configuring final product and system 
boxes and testing assemblies to meet customers' requirements.  These complex products are typically configured to 
fulfill unique end-customer requirements and many are shipped directly to our customers’ end users. 

Higher-level assembly (HLA).  We are increasingly providing more advanced assembly solutions for larger 

equipment to our customers.  These products can be very large and contain a number of printed circuit board 
assemblies, complex subassemblies and other components.  These services include assembly of kiosk products, finished 
medical products and complex electro-mechanical assemblies known as mechatronics. These products often combine 
many of the other integrated services we provide and may require more unique facility configurations than we typically 
employ. 

Fulfillment and logistic services. We provide fulfillment and logistic services to many of our customers.  
Direct Order Fulfillment (“DOF”) entails receiving orders from our customers that provide the final specifications 
required by the end-customer.  We then Build to Order (“BTO”) and Configure to Order (“CTO”) and deliver the 
product directly to the end-customer.  The DOF process relies on Enterprise Resource Planning (“ERP”) systems 
integrated with those of our customers to manage the overall supply chain from parts procurement through 
manufacturing and logistics. 

After-market support.  We provide service support for manufactured products requiring repair and/or upgrades, 

which may or may not be under a customer's warranty.  In support of certain customers, we provide these services for 

3

some products which we did not originally manufacture.  We provide in and out bound logistics required to support 
fulfillment and service.   

Regulatory requirements.  In addition, we have developed certain processes and tools to meet industry-specific 
requirements.  Among these are the tools and processes to assemble finished medical devices that meet U.S. Food and 
Drug Administration Quality Systems Regulation requirements and similar regulatory requirements in other countries. 

Our manufacturing and engineering facilities are ISO certified to 9001:2000 standards.  We have additional 

certifications and/or registrations held by certain of our facilities in various geographic locations: 

Environmental Standard ISO – 14001 – Asia, Europe 
21 CFR Part 820 (FDA) (Medical) – United States, Asia, Mexico 
Telecommunications Standard TL 9000  – United States, Asia

(cid:2)
(cid:2) ANSI/ESD (Electrostatic Discharge Control Program) S20.20 – United States 

ITAR (International Traffic and Arms Regulation) self-declaration – United States 

Customers and Market Sectors Served 

We provide services to a wide variety of customers, ranging from large multinational companies to smaller 

emerging technology companies. During fiscal 2008, we provided services to over 145 customers.  For many 
customers, we provide design and production capabilities, thereby allowing these customers to concentrate on research 
and development, concept development, distribution, marketing and sales.  This helps accelerate their time to market, 
reduce their investment in engineering and manufacturing capacity and optimize total product cost.   

Juniper Networks, Inc. (“Juniper”) accounted for 20 percent of our net sales in fiscal 2008.  Juniper and 
General Electric Company (“GE”) accounted for 21 percent and 10 percent, respectively, of our net sales in fiscal 2007 
and 19 percent and 12 percent, respectively, of our net sales in fiscal 2006.  No other customer accounted for 10 percent 
or more of our net sales in fiscal 2008, 2007 or 2006.  The loss of any of our major customers could have a significant 
negative impact on our financial results. 

Many of our large customers contract with us through independent multiple divisions, subsidiaries, production 

facilities or locations.  We believe that in most cases our sales to any one such division, subsidiary, facility or location 
are not dependent on sales to others.    

The distribution of our net sales by market sectors is shown in the following table:

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 13 in Notes to Consolidated 
Financial Statements regarding our reportable segments). 

Materials and Suppliers 

We typically purchase raw materials, including printed circuit boards and electronic components, from 

manufacturers as well as from electronic distributors.  In addition, we occasionally purchase components from 
customers. The key electronic components we purchase include 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 

4

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
components, we also purchase components used in higher-level assembly and manufacturing.  These components 
include injection-molded plastics, pressure-formed plastics, vacuum-formed plastics, sheet metal fabrications, 
aluminum extrusions, die castings and various other hardware and fastener components.  All of these components range 
from standard to highly customized and vary widely in terms of market availability and price.   

Occasional component shortages and subsequent allocations by suppliers are an inherent part of the electronics 

industry.  We actively manage our business to try to minimize our exposure to material and component shortages.  We 
have 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 the selection of components used in some new products, 
component manufacturers often provide us with priority access to materials and components, even during times of 
shortages.  We have undertaken a series of initiatives, including the utilization of in-plant stores, point-of-use programs, 
assured supply programs and other efforts, to improve our overall supply chain flexibility.  

New Business Development 

Our new business development is directed primarily through an internal effort organized around end-markets, 
or market sectors.  Each market sector has a team of dedicated, empowered resources including sector vice presidents, 
customer management vice presidents, sales account executives, customer managers, customer development directors, 
market sector analysts, and service specialists.  Our sales and marketing efforts focus on generating both new customers 
and expanding business with existing customers.  Our ability to provide a full range of product realization services is a 
marketing advantage; our service specialists participate in marketing through direct customer contact and participation 
in industry events and seminars. 

Competition 

The market for the 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.  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.  In addition, we compete against foreign, low-labor cost 
manufacturers.  This foreign, low-labor cost competition tends to focus on commodity and consumer-related products, 
which is not our focus. 

Intellectual Property 

We own various service marks, including “Plexus,” and “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 

In 2008, we completed the implementation of an integrated ERP platform that serves all manufacturing sites.  

This ERP platform augments our other management information systems and includes software from J.D. Edwards 
(now part of the Oracle Corporation) and several other vendors.  The ERP platform includes various software systems 
to enhance and standardize our ability to translate information from multiple production facilities into operational and 
financial information and create a consistent set of core business applications at our facilities worldwide.  We believe 
the related software licenses are of a general commercial character on terms customary for these types of agreements.   

Environmental Compliance 

We are subject to a variety of environmental regulations relating to air emission standards and the use, storage, 

discharge and disposal of hazardous chemicals used during our manufacturing process.  We believe that we are in 
compliance with all federal, state and foreign environmental laws and do not anticipate any significant expenditures in 
maintaining our compliance; however, there can be no assurance that violations will not occur which could have a 
material adverse effect on our financial results. 

Two European Union (“EU”) directives particularly affect our business from an environmental perspective.  
The first of these is the Restriction of the use of Certain Hazardous Substances (“RoHS”).  RoHS restricts within the 

5

 
 
EU the distribution of products containing certain substances, with lead being the restricted substance most relevant to 
us.  The second EU directive is the Waste Electrical and Electronic Equipment directive, which requires a manufacturer 
or importer, 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 EU directives affect the worldwide electronics supply-chain, we expect that there will be 
further collaborative efforts with our suppliers and customers to develop compliant processes and products, although to 
date the cost of such efforts to us and our liability for non-compliance has been nominal. 

Employees 

Our employees are one of our primary strengths, and we make a considerable effort to maintain a well-
qualified 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 developments 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 at every facility and strive for continuous 
improvement at all levels.  

We employ approximately 7,900 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 150 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, Malaysia, China 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 1A 

RISK FACTORS 

Our net sales and operating results may vary significantly from period to period. 

Our  quarterly  and  annual  results  may  vary  significantly  depending  on  various  factors,  many  of  which  are 

beyond our control. These factors include: 

(cid:2)
(cid:2)
(cid:2)
(cid:2)
(cid:2)
(cid:2)
(cid:2)

(cid:2)
(cid:2)

(cid:2)
(cid:2)

the volume and timing of customer orders relative to our capacity 
the typical short life-cycle of our customers’ products 
customers’ operating results and business conditions  
changes in our customers’ sales mix 
failures of our customers to pay amounts due to us 
volatility of customer orders for certain programs and sectors 
possible  non-compliance  with  the  statutes  and  regulations  covering  the  design,  development,  testing, 
manufacturing and labeling of medical devices   
the timing of our expenditures in anticipation of future orders 
our  effectiveness  in  planning  production  and  managing  inventory,  fixed  assets  and  manufacturing 
processes
changes in cost and availability of labor and components and 
changes in U.S. and global economic and political conditions and world events. 

The majority of our net sales come from a relatively small number of customers and a limited number of market 
sectors;  if  we  lose  any  of  these  customers  or  there  are  problems  in  those  market  sectors,  our  net  sales  and 
operating results could decline significantly.

Net sales to our ten largest customers have represented a majority of our net sales in recent periods.  Our ten 
largest customers accounted for approximately 60 percent, 61 percent and 59 percent of our net sales for fiscal 2008, 
2007 and 2006, respectively.  For fiscal 2008 there was one customer that represented 10 percent or more of our net 
sales.  For 2007 and 2006, there were two customers that represented 10 percent or more of our net sales.  Our principal 
customers may vary from period to period, and our principal customers may not continue to purchase services from us 
at current levels, or at all.  Significant reductions in net sales to any of these customers, or the loss of other major 
customers, could seriously harm our business.   

6

 
In addition, we focus our net sales to customers in only a few market sectors.  For example, net sales to 

customers in the wireline/networking sector recently have increased significantly in absolute dollars, making us more 
dependent upon the performance of that sector and the economic and business conditions that affect it.  In addition, net 
sales in the defense/security/aerospace sector have become increasingly important in some periods; however, net sales 
in this sector are particularly susceptible to significant period-to-period variations.  Any weakness in the market sectors 
in which our customers are concentrated could affect our business and results of operations. 

The global credit market crisis and economic weakness may adversely affect our earnings, liquidity and financial 
condition.  

Global  financial  and  credit  markets  recently  have  been,  and  continue  to  be,  extremely  unstable  and 
unpredictable.  Worldwide economic conditions have been weak and may be further deteriorating.  The instability of 
the markets and weakness of the economy could affect the demand for our customers' products, the amount, timing and 
stability  of  their  orders  to  us,  the  financial  strength  of  our  customers  and  suppliers,  their  ability  or  willingness  to  do 
business with us, our willingness to do business with them, and/or our suppliers' and customers' ability to fulfill their 
obligations to us.  These factors could adversely affect our operations, earnings and financial condition.   

In addition, continued, and potentially increased, volatility, instability and weakness in the financial and credit 

markets could affect our ability to sell our investment securities and other financial assets, which in turn could 
adversely affect our liquidity and financial position.  We encountered a situation in which we were unable to make such 
sales as described below in Item 7A, “Quantitative and Qualitative Disclosures About Market Risk – Auction Rate 
Securities.”  This instability also could affect the prices at which we could make any such sales, which also could 
adversely affect our earnings and financial condition.  These conditions could also negatively affect our ability to secure 
funds or raise capital, if needed. 

Our customers do not make long-term commitments and may cancel or change their production requirements. 

EMS companies must respond quickly to the requirements of their customers.  We generally do not obtain 

firm, long-term purchase commitments from our customers.  Customers also cancel requirements, change production 
quantities or delay production for a number of reasons that are beyond our control.  The success of our 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 based on our estimates of customers’ requirements, 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.  The short-term nature of our 
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.  Since many of our operating expenses are fixed, a 
reduction in customer demand can harm our operating results.   Moreover, since our margins vary across customers and 
specific programs, a reduction in demand with higher margin customers or programs will have a more significant 
adverse effect on our operating results. 

Rapid increases in customer requirements may stress personnel and other capacity resources.  We may not 
have sufficient resources at any given time to meet all of our customers’ demands or to meet the requirements of a 
specific program. 

Defense contracting can be subject to extensive procurement processes and other factors that can affect the 

timing and duration of contracts and orders.  For example, defense orders are subject to continued Congressional 
appropriations for these programs, as well as continued determinations by the Department of Defense regarding 
whether to continue them.  Products for the military are also subject to continued testing of their operations in the field 
and changing military operational needs, which could affect the possibility and timing of future orders.  While those 
arrangements may result in a significant amount of net sales in a short period of time as happened in the first half of 
fiscal 2008, they may or may not result in continuing long-term projects or relationships.  Even in the case of 
continuing long-term projects or relationships, orders in the defense sector can be episodic and vary significantly from 
period to period. 

7

 
 
 
 
Our manufacturing services involve inventory risk. 

Most of our contract manufacturing services are provided on a turnkey basis, under which we purchase some, 

or all, of the required raw materials and component parts.  Excess or obsolete inventory could adversely affect our 
operating results. 

In our turnkey operations, we order materials and components based on customer forecasts and/or orders.  

Suppliers may require us to purchase materials and components in minimum order quantities that may exceed customer 
requirements.  A customer’s cancellation, delay or reduction of forecasts or orders can also result in excess inventory or 
additional expense to us.  Engineering changes by a customer may result in obsolete raw materials or component parts.  
While we attempt to cancel, return or otherwise mitigate excess and obsolete materials and components and require 
customers to reimburse us for excess and obsolete inventory, we may not actually be reimbursed timely or be able to 
collect on these obligations.   

In addition, we provide managed inventory programs for some of our key customers under which we hold and 
manage finished goods or work-in-process inventories.  These managed inventory programs result in higher inventory 
levels, further reduce our inventory turns and increase our financial exposure with such customers.  Even though our 
customers generally have contractual obligations to purchase such inventories from us, we remain subject to the risk of 
enforcing those obligations.  

We may experience raw material and component parts shortages and price fluctuations. 

We do not have any long-term supply agreements.  At various times, we have experienced raw material and 
component parts shortages due to supplier capacity constraints or their failure to deliver.  At times, raw material and 
component parts shortages have been prevalent due to industry-wide conditions, and such shortages can be expected to 
recur from time to time.  World events, such as foreign government policies, terrorism, armed conflict, economic 
recession and epidemics, could also affect supply chains.  We rely on a limited number of suppliers for many of the raw 
materials and component parts used in the assembly process and, in some cases, may be required to use suppliers that 
are the sole provider of a particular raw material or component part.  Such suppliers may encounter quality problems or 
financial difficulties which could preclude them from delivering raw materials or component parts timely or at all.  
Supply shortages and delays in deliveries of raw materials or component parts have resulted in delayed production of 
assemblies, which have increased our inventory levels and adversely affected our operating results in certain periods.  
An inability to obtain sufficient inventory on a timely basis could also harm relationships with our customers. 

Raw material and component part supply shortages and delays in deliveries have also resulted in increased 
pricing.  While many of our customers permit quarterly or other periodic adjustments to pricing based on changes in 
raw material or component part prices and other factors, we typically bear the risk of 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.  Conversely, raw material and component part price reductions have contributed positively to our operating 
results in the past.  Our inability to continue to benefit from such reductions in the future could adversely affect our 
operating results.   

Failure to manage periods of growth or contraction, if any, may seriously harm our business. 

Our industry frequently sees periods of expansion and contraction to adjust to customers’ needs and market 
demands.  Plexus regularly contends with these issues and must carefully manage its business to meet customer and 
market requirements.  If we fail to manage these growth and contraction decisions effectively, we can find ourselves 
with either excess or insufficient resources and our business, as well as our profitability, may suffer. 

Expansion can inherently include additional costs and start-up inefficiencies. We are currently contemplating 
possible expansion of our operations to other countries.  In fiscal 2007, we expanded our operations in Asia, including 
the addition of a third facility in Penang, Malaysia, as well as the doubling of capacity in our existing facility in 
Xiamen, China.  We recently announced a planned expansion in Hangzhou, China.  If we are unable to effectively 
manage our currently anticipated growth, or related anticipated net sales are not realized, our operating results could be 
adversely affected.  In addition, we may expand our operations in new geographical areas where currently we do not 
operate.  Other risks of current or future expansion include: 

(cid:2)

(cid:2)

the inability to successfully integrate additional facilities or incremental capacity and to realize anticipated 
synergies, economies of scale or other value 
additional fixed costs which may not be fully absorbed by new business 

8

 
 
 
 
 
 
 
(cid:2)

(cid:2)

(cid:2)
(cid:2)

difficulties in the timing of expansions, including delays in the implementation of construction and 
manufacturing plans 
diversion of management’s attention from other business areas during the planning and 
implementation of expansions 
strain placed on our operational, financial and other systems and resources and 
inability to locate sufficient customers, employees or management talent to support the expansion. 

Periods of contraction or reduced net sales create other challenges.  We must determine whether facilities 

remain viable, whether staffing levels need to be reduced, and how to respond to changing levels of customer demand.  
While maintaining multiple facilities or higher levels of employment entail short-term costs, reductions in facilities 
and/or employment could impair our ability to respond to market improvements or to maintain customer relationships.  
Our decisions to reduce costs and capacity can affect our short-term and long-term results.  When we make decisions to 
reduce capacity or to close facilities, we frequently incur restructuring charges. 

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.  For example, we recently announced that we 
would close our Ayer, Massachusetts facility in fiscal 2009, even though we are expanding in other areas.  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 and expansion in another location, such as those 
noted above.   

Operating in foreign countries exposes us to increased risks, including foreign currency risks. 

We have operations in China, Malaysia, Mexico and the United Kingdom, which in the aggregate represented 
approximately 39 percent of our revenues for fiscal 2008, compared to 37 percent of revenue in fiscal 2007.  We have 
announced expansion plans in China and are considering expanding to additional countries.  We also purchase a 
significant number of components manufactured in foreign countries.  These international aspects of our operations 
subject us to the following risks that could materially impact our operating results: 

(cid:2)
(cid:2)
(cid:2)
(cid:2)
(cid:2)
(cid:2)

economic, political or civil instability 
transportation delays or interruptions  
foreign exchange rate fluctuations 
difficulties in staffing and managing foreign personnel in diverse cultures  
the effects of international political developments and 
foreign regulatory requirements. 

We do not generally “hedge” foreign currencies.  As our foreign operations expand, our failure to adequately 
hedge foreign currency transactions and/or the currency exposures associated with assets and liabilities denominated in 
non-functional currencies could adversely affect our consolidated 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 facility in 
Mexico operates under the Mexican Maquiladora program, which provides for reduced tariffs and eased import 
regulations; we could be adversely affected by changes in that program or our failure to comply with its requirements.  
Also, our Malaysian and Chinese subsidiaries currently receive favorable tax treatments from these governments which 
extend for approximately 11 years and 5 years, respectively, which may not be extended.  Finally, China and Mexico 
have passed new tax laws that took effect on January 1, 2008.  These new laws did not materially impact our tax rates in 
fiscal 2008, but may result in higher tax rates on our operations in those countries in future periods. 

We and our customers are subject to extensive government regulations. 

We are subject to extensive regulation relating to the products we design and manufacture and as to how we 
conduct  our  business.    These  regulations  affect  the  sectors  we  serve  and  every  aspect  of  our  business,  including  our 
labor,  employment,  workplace  safety,  environmental  and  import/export  practices,  and  many  other  facets  of  our 
operations.  Our failure to comply with these regulations could seriously affect our operations and profitability.  

Our medical sector business, which represented approximately 21 percent of our net sales for fiscal 2008, is 
subject to substantial government regulation, primarily from the federal Food and Drug Administration (“FDA”) and 

9

 
 
 
 
 
 
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 regulations can result in, among other things, 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 the 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.  Failure or 
noncompliance could have an adverse effect on our reputation as well as our results of operations.  

We also design and manufacture products for customers in the defense and aerospace industries.  Companies 

that design and manufacture products for these industries face significant regulation by the Department of Defense, 
Federal Aviation Authority, and other governmental agencies.  Failure to comply with those requirements could result 
in fines, penalties, injunctions, criminal prosecution, and an inability to participate in contracts with the government or 
their contractors, any of which could materially affect our financial condition and results of operations.   

The end-markets for most of our customers in the wireline/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 demand and profitability of 
the sector and therefore directly impact the demand for products that we manufacture.

At the corporate level, as a publicly-held company, we are subject to increasingly stringent laws, regulation 
and other requirements affecting among other things our accounting, corporate governance practices, and securities 
disclosures.  Our failure to comply with these requirements could materially affect our financial condition and results of 
operations.   

The growth and changing requirements of our business are imposing on us heightened import and export 
compliance requirements.  We have been notified that we are a potential candidate for audit by U.S. Customs.  The 
timing and scope of this audit is uncertain.  In preparation for a potential audit, we have reassessed internal policies, 
procedures and controls respecting import law compliance.  We have uncovered some deficiencies during this 
assessment but do not yet know whether such deficiencies affected duties owed by us and, if so, whether they will have 
a material adverse effect on Plexus or our results of operations. 

Our operations are subject to federal, state, and local environmental regulations pertaining to air, water, and 
hazardous waste and the health and safety of our workplace.  If we fail to comply with present and future regulations, 
we could be subject to 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  associated  with  the  ongoing 
operation of our business or remediation efforts.  

Our customers are also required to comply with various government regulations and legal requirements, 

including many of the industry-specific regulations which we discuss above.  Our customers' failure to comply could 
affect their businesses, which in turn would affect our sales to them.  The processes we engage in for these customers 
must comply with the relevant regulations.  In addition, if our customers are required by regulation or other legal 
requirements to make changes in their product lines, these changes could significantly disrupt particular projects for 
these customers and create inefficiencies in our business.

If we are unable to maintain our engineering, technological and manufacturing process expertise, our results 
may be adversely affected.

The markets for our manufacturing and engineering services are characterized by rapidly changing technology 

and evolving process developments.  Our manufacturing and design processes are also subject to these factors.  The 
continued success of our business will depend upon our continued ability to: 

retain our qualified engineering and technical personnel 

(cid:2)
(cid:2) maintain and enhance our technological capabilities 
(cid:2)
(cid:2)
(cid:2)

successfully manage the implementation and execution of information systems  
develop and market manufacturing services which meet changing customer needs and 
successfully anticipate, or respond to, technological changes 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 

10

 
 
 
requirements may render our equipment, inventory or processes obsolete or noncompetitive.  In addition, we may have 
to acquire new design, 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 liquidity and negatively affect our operating results.  Our failure to anticipate and adapt to our customers’ 
changing technological needs and requirements could have an adverse effect on our business. 

Start-up costs and inefficiencies related to new or transferred programs can adversely affect our operating 
results.

The management of labor and production 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 and operating margins.  These factors are particularly evident in the early stages of the life-cycle of new 
products and new programs as well as in program transfers between facilities.  We are managing a number of new 
programs at any given time.  Consequently, we are exposed to these factors.  In addition, if any of these new programs 
or new customer relationships were terminated, our operating results could worsen, particularly in the short term. 

The effects of these start-up costs and inefficiencies can also occur when we transfer programs between 

locations.  We conduct those transfers on a regular basis to address factors such as meeting customer needs, seeking 
long-term efficiencies or responding to market conditions.  As a result of our decision to close our Ayer, Massachusetts 
facility, we will also be transitioning customer programs from that site to other Plexus facilities.  Although we try to 
minimize the potential losses arising from transitioning customer programs between Plexus facilities, there are inherent 
risks that such transitions can result in operational inefficiencies and the disruption of programs and customer 
relationships. 

There may be problems with the products we design or manufacture that could result in claims against us and 
reduced demand for our services. 

The products that we design and/or manufacture may be subject to liability or claims in the event that defects 

are discovered or alleged.  We design and manufacture products to our customers’ specifications, many of which are 
highly complex.  Despite our quality control and quality assurance efforts, problems may occur, or may be alleged, in 
the design and/or manufacturing of these products.  Problems in the products we manufacture, whether real or alleged, 
whether caused by faulty customer specifications or in the design or manufacturing processes or by a component defect, 
and whether or not we are responsible, may result in delayed shipments to customers and/or reduced or cancelled 
customer orders.  If these problems were to occur in large quantities or too frequently, our business reputation may also 
be tarnished.  In addition, problems may result in liability claims against us, whether or not we are responsible.  These 
potential claims may include damages for the recall of a product and/or injury to person or property.  Even if customers 
or third parties, such as component suppliers, are responsible for defects, they may not, or may not be able to, assume 
responsibility for any such costs or required payments to us.  We occasionally incur costs defending claims and any 
such disputes could affect our business relationships.   

Intellectual property infringement claims against our customers or us could harm our business.  

Our design and manufacturing services and the products offered by our customers involve the creation and use 

of intellectual property rights, which subject us and our customers to the risk of claims of intellectual property 
infringement from third parties.  In addition, our customers may require that we indemnify them against the risk of 
intellectual property infringement.  If any claims are brought against us or our customers for infringement, whether or 
not these have merit, we could be required to expend significant resources in defense of those claims.  In the event of an 
infringement claim, we may be required to spend a significant amount of money to develop non-infringing alternatives 
or obtain licenses.  We may not be successful in developing alternatives or obtaining licenses on reasonable terms or at 
all.  Infringement by our customers could cause them to discontinue production of some of their products, potentially 
with little or no notice, which may reduce our net sales to them and disrupt our production. 

Additionally, if third parties on whom we rely for products or services, such as component suppliers, are 

responsible for an infringement (including through the supply of counterfeit parts), we may or may not be able to hold 
them responsible and we may incur costs in defending claims or providing remedies.  Such infringements may also 
cause our customers to abruptly discontinue selling the impacted products, which would adversely affect our net sales 
of those products, and could affect our customer relationships more broadly.

We are defendants in a securities class action lawsuit.  

Two securities class action lawsuits were filed against us and several of our current or former officers and/or 
directors during June 2007.  The two actions were consolidated, and a consolidated class action complaint was filed on 
February 1, 2008.  Although the Company and the individual defendants filed a motion to dismiss the consolidated 
class action complaint, the plaintiff has asked the court to deny our motion and the court has not yet held a hearing or 
ruled on it.  The consolidated complaint alleges securities law violations and seeks unspecified damages relating 
generally to the Company’s statements regarding its defense sector business in early calendar 2006.  We could be 
subject to additional or related lawsuits or other inquiries in connection with this matter.  The defense of this lawsuit, 
and any future lawsuits, could result in the diversion of management’s time and attention away from business 
operations and negative developments with respect to the lawsuits and the costs incurred defending ourselves could 
have an adverse impact on our business and our stock price.  Adverse outcomes or settlements could also require us to 
pay damages or incur liability for other remedies that could have a material adverse effect on our consolidated results of 
operations, financial position and cash flows. 

Our products are for the electronics industry, which produces technologically advanced products with relatively 
short life-cycles. 

Factors affecting the electronics industry, in particular short product life-cycles, could seriously affect our 

customers and, as a result, Plexus.  These factors include: 

(cid:2)

(cid:2)

(cid:2)

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 
and
the potential that our customers’ products may become obsolete or the failure of our customers’ products 
to gain widespread commercial acceptance. 

Even if our customers successfully respond to these market challenges, their responses, including any 
consequential changes we must make in our business relationships with them and our production for them, can affect 
our production cycles, inventory management and results of operations. 

Increased competition may result in reduced demand or reduced prices for our services. 

The EMS 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 EMS providers with global operations, as well as those which operate 
on only a local or regional basis.  In addition, current and prospective customers continually evaluate the merits of 
manufacturing products internally and may choose to manufacture products themselves rather than outsource that 
process.  Consolidations and other changes in the EMS industry result in a 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 ourselves.  These competitors may: 

(cid:2)
(cid:2)
(cid:2)
(cid:2)
(cid:2)
(cid:2)

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 and 
be better positioned to compete on price for their services. 

We may operate at a cost disadvantage compared to other EMS providers which have lower internal cost 

structures or have greater direct buying power with component suppliers, distributors and raw material suppliers.  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 become increasingly competitive.  Increased 
competition could result in price reductions, reduced sales and margins or loss of market share. 

12

 
 
 
 
 
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 services of our key technical and management personnel, 

and on our ability to attract and retain qualified employees, particularly 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.   

From time to time, there are changes and developments, such as retirements, disability, death and other 
terminations of service that affect our executive officers and other key employees.  Transitions of responsibilities 
among officers and key employees, particularly those that are unplanned, inherently can cause disruptions to our 
business and operations, which could have an effect on our results. 

Energy price increases may reduce our profits. 

We use some components made with petroleum-based materials. In addition, we use various energy sources 
transporting, producing and distributing products.  Energy prices have recently been subject to increases and volatility 
caused by market fluctuations, supply and demand, currency fluctuation, production and transportation disruption, 
world events, and changes in governmental programs. 

Energy price increases raise both our material and operating costs.  We may not be able to increase our prices 

enough to offset these increased costs.  Increasing our prices also may reduce our level of future customer orders and 
profitability. 

We may fail to successfully complete future acquisitions and may not successfully integrate acquired businesses, 
which could adversely affect our operating results. 

We have previously grown, in part, through acquisitions.  If we were to pursue future growth through 
acquisitions, this would involve significant risks that could have a material adverse effect on us.  These risks include: 

Operating risks, such as: 

(cid:2)
(cid:2)
(cid:2)
(cid:2)
(cid:2)

(cid:2)

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

Financial risks, such as: 

(cid:2)
(cid:2)
(cid:2)

(cid:2)
(cid:2)
(cid:2)

the use of cash resources, or incurrence of additional debt and related interest expense 
the dilutive effect of the issuance of additional equity securities 
the inability to achieve expected operating margins to offset the increased fixed costs associated with 
acquisitions, and/or inability to increase margins of acquired businesses to our desired levels 
the incurrence of large write-offs or write-downs 
the impairment of goodwill and other intangible assets and 
the unforeseen liabilities of the acquired businesses. 

We may fail to secure or maintain necessary financing. 

Under our Amended Credit Facility, we have borrowed $150 million in term loans and can borrow up to $200 

million in revolving loans of which $100 million is currently available, depending upon compliance with its defined 
covenants and conditions.  However, we cannot be certain that the credit facility will provide all of the financing 
capacity that we will need in the future or that we will be able to change the credit facility or revise covenants, if 
necessary or appropriate in the future, to accommodate changes or developments in our business and operations. 

13

 
 
 
 
 
Our future success may depend on our ability to obtain additional financing and capital to support possible 
future growth and future initiatives.  We may seek to raise capital by issuing additional common stock, other equity 
securities or debt securities, modifying our existing credit facilities or obtaining new credit facilities or 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 securities to raise capital, it may be dilutive to 
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. 

If we are unable to maintain effective internal control over our financial reporting, investors could lose 
confidence in the reliability of our financial statements, which could result in a reduction 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’s internal control over financial reporting in their annual reports on 
Form 10-K; that report must contain an assessment by management of the effectiveness of our internal control over 
financial reporting. In addition, the independent registered public accounting firm auditing a company’s financial 
statements must attest to and report on the effectiveness of the company’s internal control over financial reporting.  

We are continuing our comprehensive efforts to comply with Section 404 of the Sarbanes-Oxley Act.  If we 

are unable to maintain effective internal control over financial reporting, this could lead to a failure to meet our 
reporting obligations to the SEC, which in turn could result in an adverse reaction in the financial markets due to a loss 
of confidence in the reliability of our financial statements. 

The price of our common stock 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 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 share prices for technology companies in particular, have from 
time to time experienced extreme volatility, including weakness, that sometimes has been unrelated to the operating 
performance of these companies.  These broad market and industry fluctuations, and concerns affecting the economy 
generally, may adversely affect the market price of our common stock, regardless of our operating results.   

Among other things, volatility and weakness in our stock price could mean that investors may not be able to 

sell their shares at or above the prices that they paid.  Volatility and weakness could also impair our 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.

LEGAL PROCEEDINGS

Two securities class action lawsuits were filed in the United States District Court for the Eastern District of 

Wisconsin on June 25 and June 29, 2007, against the Company and certain Company officers and/or directors.  On 
November 7, 2007, the two actions were consolidated, and a consolidated class action complaint was filed on February 
1, 2008.  The consolidated complaint names the Company and the following individuals as defendants:  Dean A. Foate, 
President, Chief Executive Officer and a Director of the Company; F. Gordon Bitter, the Company's former Senior Vice 
President and Chief Financial Officer; and Paul Ehlers, the Company’s former Executive Vice President and Chief 
Operating Officer.  The consolidated complaint alleges securities law violations and seeks unspecified damages relating 
generally to the Company’s statements regarding its defense sector business in early calendar 2006.  On April 15, 2008, 
the Company and the individual defendants filed a motion to dismiss the consolidated class action complaint.  The 
plaintiff is opposing the dismissal.  The briefing on the defendants’ motion has been completed; however, the Court has 
not yet held a hearing or ruled on the motion. 

The Company believes the allegations in the consolidated complaint are wholly without merit and it intends to 
vigorously defend against them.  Since these matters are in the preliminary stages, the Company is unable to predict the 
scope or outcome or quantify their eventual impact, if any, on the Company.  At this time, the Company is also unable 
to estimate associated expenses or possible losses.  The Company maintains insurance that may reduce its financial 
exposure for defense costs and liability for an unfavorable outcome, should it not prevail.

The  Company  is  party  to  certain  other  lawsuits  in  the  ordinary  course  of  business.   Management  does  not 
believe  that  these  proceedings  or  the  securities  class  actions  referenced  above,  individually  or  in  the  aggregate,  will 
have a material adverse effect on the Company's consolidated financial position, results of operations or cash flows.

In fiscal 2008, we recorded pre-tax restructuring costs totaling $2.1 million which related primarily to the 
closure of our Ayer, Massachusetts (“Ayer”) facility and the reduction of our workforce in Juarez, Mexico 
(“Juarez”). 

In fiscal 2007, we recorded pre-tax restructuring and impairment costs totaling $1.8 million which related 
primarily to the closure of our Maldon, England (“Maldon”) facility and the reduction of our workforces in 
Juarez and Kelso, Scotland (“Kelso”). 

In fiscal 2006, we recorded a favorable adjustment of $17.7 million in the Consolidated Statements of 
Operations related to the reduction of a previously recorded valuation allowance on our deferred income tax 
assets in the United States.  In addition, we recorded $0.5 million loss, net of tax, related to a cumulative effect 
of a change in accounting principle related to the adoption of Financial Accounting Standards Board 
Interpretation No. 47, “Accounting for Conditional Asset Retirement Obligations.” 

In fiscal 2005, we recorded pre-tax restructuring and impairment costs totaling $39.2 million. The restructuring 
and impairment costs were associated with the impairments of goodwill related to our operations in the United 
Kingdom and Mexico, the closure of our Bothell, Washington (“Bothell’) facility (announced in fiscal 2004), 
the write-off of the remaining elements of a shop floor data-collection system, and other restructuring costs. 
We also recorded certain adjustments to previously recognized restructuring and impairment costs.

In fiscal 2004, we recorded restructuring and impairment costs of approximately $9.3 million, which were 
primarily associated with the remaining lease obligations for two previously abandoned facilities near Seattle, 
Washington (the “Seattle facilities”), severance costs associated with the closure of our Bothell facility, the 
impairment of certain abandoned software, and the remaining lease obligation and severance costs related to 
the consolidation of a satellite PCB-design office in Hillsboro, Oregon into another Plexus design office.  In 
addition, we recorded a $36.8 million valuation allowance for deferred income tax assets. 

We have not paid cash dividends in the past and do not anticipate paying them in the foreseeable future. 

ITEM 7.  

MANAGEMENT’S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND 
RESULTS OF OPERATIONS 

OVERVIEW

Plexus Corp. and its subsidiaries (together “Plexus,” the “Company,” or “we”) participate in the Electronic 

Manufacturing Services (“EMS”) industry.  We provide product realization services to original equipment manufacturers 
(“OEMs”) and other technology companies in the wireline/networking, wireless infrastructure, medical, 
industrial/commercial and defense/security/aerospace market sectors.  We provide advanced electronics design, 
manufacturing and testing services to our customers with a focus on the mid-to-lower-volume, higher-mix segment of 
the EMS market.  Our customers’ products typically require exceptional production and supply-chain flexibility, 
necessitating an optimized demand-pull-based manufacturing and supply chain solution across an integrated global 
platform.  Many of our customers’ products require complex configuration management and direct order fulfillment to 
their customers across the globe.  In such cases we provide global logistics management and after-market service and 
repair.   Our customers’ products may have stringent requirements for quality, reliability and regulatory compliance.  We 
offer our customers the ability to outsource all phases of product realization, including product specifications; 
development, design and design validation; regulatory compliance support; prototyping and new product introduction; 
manufacturing test equipment development; materials sourcing, procurement and supply-chain management; product 
assembly/manufacturing, configuration and test; order fulfillment, logistics and service/repair.   

Plexus is passionate about its goal to be the best EMS company in the world at providing services for customers 

that have mid-to-lower-volume requirements and a higher mix of products.  We have tailored our engineering services, 
manufacturing operations, supply-chain management, workforce, business intelligence systems, financial goals and 
metrics specifically to support these types of programs.  Our flexible manufacturing facilities and processes are designed 
to accommodate customers with multiple product-lines and configurations as well as unique quality and regulatory 
requirements.  Each of these customers is supported by a multi-disciplinary customer team and one or more uniquely 
configured “focus factories” supported by a supply-chain and logistics solution specifically designed to meet the 
flexibility and responsiveness required to support that customer’s fulfillment requirements.  

Our go-to-market strategy is also tailored to our target market sectors and business strategy.  We have business 
development and customer management teams that are dedicated to each of the five sectors we serve.  These teams are 
accountable for understanding the sector participants, technology, unique quality and regulatory requirements and 
longer-term trends.  Further, these teams help set our strategy for growth in their sectors with a particular focus on 
expanding the services and value-add that we provide to our current customers while strategically targeting select new 
customers to add to our portfolio. 

Our financial model is aligned with our business strategy, with our primary focus to earn a return on invested 

capital (“ROIC”) in excess of our weighted average cost of capital (“WACC”).  The smaller volumes, flexibility 
requirements and fulfillment needs of our customers typically result in greater investments in inventory than many of 
our competitors, particularly those that provide EMS services for high-volume, less complex products with less 
stringent requirements (such as consumer electronics).  In addition, our cost structure relative to these peers includes 
higher investments in selling and administrative costs as a percentage of sales to support our sector-based go-to-market 
strategy, smaller program sizes, flexibility, and complex quality and regulatory compliance requirements.  By 
exercising discipline to generate a ROIC in excess of our WACC, our goal is to ensure that Plexus creates a value 
proposition for our shareholders as well as our customers. 

Our customers include both industry-leading original equipment manufacturers and technology companies that 

have never manufactured product internally. As a result of our focus on serving market sectors that rely on advanced 
electronics technology, our business is influenced by technological trends such as the level and rate of development of 
telecommunications infrastructure and the expansion of networks and use of the Internet.  In addition, the federal Food 

21

and Drug Administration’s approval of new medical devices, defense procurement practices and other government 
approval and regulatory processes can affect our business.  Our business has also benefited from the trend to increased 
outsourcing by OEMs. 

We provide most of our contract manufacturing services on a turnkey basis, which means that we procure 

some or all of the materials required for product assembly.  We provide some services on a consignment basis, which 
means that the customer supplies the necessary materials, and we provide the labor and other services required for 
product assembly.  Turnkey services require material procurement and warehousing, in addition to manufacturing, and 
involve greater resource investments than consignment services.  Other than certain test equipment and software used 
for internal manufacturing, we do not design or manufacture our own proprietary products. 

The following information should be read in conjunction with our consolidated financial statements included 

herein and “Risk Factors” included in Item 1A herein. 

EXECUTIVE SUMMARY 

Fiscal 2008.  Net sales for fiscal 2008 increased by $295.3 million, or 19 percent, over fiscal year 2007 to 
$1,841.6 million.  Our sector-focused business development strategy delivered growth in all five of our end-market 
sectors.  Net sales in the defense/security/aerospace sector exhibited the highest percentage growth due to new program 
wins and strong end-market demand from the top three customers in this sector and strong demand from our largest 
defense customer in the first half of fiscal 2008.  However, net sales to this customer decreased significantly in the 
second half of fiscal 2008, from $82.6 million in the first half of the year to $3.1 million in the second half.  Net sales in 
our wireline/networking sector also increased due to increased demand from several customers, including Juniper 
Networks, Inc. (“Juniper”), our largest customer.  

Gross margin was 11.2 percent for fiscal 2008, which compared favorably to 10.6 percent for fiscal 2007.  

Gross margin in fiscal 2008 benefited from the operating leverage gained on increased revenues while moderating the 
increase in fixed manufacturing costs, favorable changes in the customer and sector mix and further operational 
efficiencies.

Selling and administrative expenses were $100.8 million for fiscal 2008, an increase of $18.6 million, or 22.6 
percent, from the $82.3 million for fiscal 2007.  The current-year period had increased variable incentive compensation 
of $5.5 million over the prior-year period, as well as increased stock-based compensation expense of $1.9 million.  In 
addition, salaries and benefits increased, reflecting wage increases and additional headcount.   

Net income for fiscal 2008 was $84.1 million and diluted earnings per share were $1.92, which compared 

favorably to net income of $65.7 million, or $1.41 per diluted share, for fiscal 2007.  Fiscal 2008 was favorably 
impacted by an 18 percent effective tax rate, a decrease from the 22 percent effective tax rate in fiscal 2007.        

Fiscal 2007.  Net sales for fiscal 2007 increased by $85.7 million, or 6 percent, over fiscal 2006 to $1,546.3 

million.  Net sales in our wireline/networking sector in fiscal 2007 were positively impacted by increased demand from 
several customers, including Juniper. Our wireless infrastructure sector experienced flat revenues, while our remaining 
sectors were impacted unfavorably by reduced demand from several customers.  Net sales in the 
defense/security/aerospace sector experienced episodic demand from our largest defense sector customer during fiscal 
2007.   

Gross margin was 10.6 percent for fiscal 2007, which compared unfavorably to 10.9 percent for fiscal 2006.  

Gross margin in fiscal 2007 was negatively impacted by increased fixed manufacturing costs to support growth in Asia, 
lower pricing, changes in customer mix and the write-down of inventory. 

Selling and administrative expenses were $82.3 million for fiscal 2007, an increase of $3.8 million or 4.9 

percent over fiscal 2006.  The increase was attributable to additional headcount and associated salaries and expenses to 
augment business development as well as increased stock-based compensation expense, partially offset by less variable 
incentive compensation.  

Net income for fiscal 2007 was $65.7 million, and diluted earnings per share were $1.41, which compared 

unfavorably to net income of $100.0 million, or $2.15 per diluted share for fiscal 2006.  Fiscal 2006 included a 
favorable adjustment of $17.7 million to the tax provision for a reduction in the valuation allowance on deferred income 
tax assets in the United States, whereas fiscal 2007 was unfavorably impacted by a 22 percent effective tax rate.  

22

Other. The effective income tax rates for fiscal 2008, 2007 and 2006 were 18 percent, 22 percent and (20.6) 

percent, respectively.  The decrease in our effective tax rate from fiscal 2007 to fiscal 2008 is primarily due to a higher 
proportion of income in Malaysia and China, where we currently have reduced tax rates due to tax holidays which 
extend through 2019 and 2013, respectively.  Our effective tax rate increased in fiscal 2007 from fiscal 2006 because 
we recorded a tax provision associated with U.S. pre-tax income in fiscal 2007 whereas no such tax provision was 
required for the prior fiscal year.  During fiscal 2006, we recorded minimal income tax expense as a result of the 
establishment in fiscal 2004 of a full valuation allowance on U.S. deferred income tax assets and increased income in 
Malaysia and China, which benefit from tax holidays, and reduced pre-tax income in the United Kingdom.  In the 
fourth quarter of fiscal 2006, we reversed $17.7 million of the previously recorded valuation allowance as a credit to 
income tax.     

We currently expect the annual effective tax rate for fiscal 2009 to be approximately 15 percent due to the mix 

of pre-tax income expected to occur in each tax jurisdiction.  Due to significant tax rate differences in the jurisdictions 
in which we operate, our effective tax rate can change significantly as the relative amount of income earned in these 
jurisdictions changes.  China and Mexico passed new tax laws that were effective on January 1, 2008.  Those new laws 
may result in higher tax rates on our operations in those countries in fiscal 2009 and beyond.     

ROIC.  One of our metrics for measuring financial performance is after-tax ROIC, which in fiscal 2008 

exceeded our estimated 15 percent WACC.  We define after-tax ROIC as tax-effected operating income, excluding 
unusual charges, divided by average capital employed over a rolling five quarter period.  Capital employed is defined as 
equity plus debt, less cash and cash equivalents and short-term investments.  ROIC was 20.1 percent, 17.6 percent and 
28.8 percent for fiscal 2008, 2007 and 2006, respectively.  See the table below for our calculation of ROIC (dollars in 
millions):

For a reconciliation of ROIC to our financial statements that were prepared using generally accepted 

accounting priciples (“GAAP”), see Exhibit 99.1 to this annual report on Form 10-K, which exhibit is incorporated 
herein by reference. 

Fiscal 2009 outlook.  Our financial goals for fiscal 2009 are to build on the prior year’s achievements and to 

focus on attaining organic net sales growth and further improvements in operating income while maintaining our ROIC 
above our estimated WACC.  Over the past several years, we have consistently set our target annual revenue growth 
range at 15 percent to 18 percent.  However, given the current macroeconomic environment and our uncertainty in 
longer range customer forecasts, we are refraining from providing full year fiscal 2009 revenue targets until forecasts 
begin to stabilize and visibility improves.       

We currently expect net sales in the first quarter of fiscal 2009 to be in the range of $455 million to $480 
million; however, our results will ultimately depend upon the actual level of customer orders, which could vary.  
Assuming that net sales are in the range noted above, we would currently expect to earn, before any restructuring and 
impairment costs, between $0.38 to $0.43 per diluted share in the first quarter of fiscal 2009.  

See “Risk Factors,” in Item 1A hereof, which sets forth some of the other factors which could effect our net 

sales, operations and earnings going forward.

(cid:2) United States:   

Net sales for fiscal 2008 increased $187.2 million, or 17.3 percent, over fiscal 2007 to $1,267.9 million.  This 
growth reflected higher demand from an unnamed defense/security/aerospace customer, a wireless 
infrastructure customer and several wireline /networking customers, including Juniper.  Operating income for 
fiscal 2008 improved $19.1 million from fiscal 2007 primarily as a result of increased sales and favorable 
changes in customer mix, offset by bad debt expense of approximately $1.3 million related to a customer that 
filed Chapter 11 bankruptcy during the year.  In addition, operating income in the prior-year period was 
negatively impacted by a $5.9 million write-down of inventories.        

Net sales for fiscal 2007 increased $28.2 million, or 2.7 percent, over fiscal 2006 to $1,080.7 million.  This 
growth reflected increased sales to several customers within the wireline/networking sector, including Juniper.  
Operating income for fiscal 2007 declined $6.1 million from fiscal 2006, due to an unfavorable customer mix, 
lower pricing, a $1.3 million warranty-related charge and a $5.9 million write-down of inventories in the 
second quarter of fiscal 2007 due to financial concerns about a customer.  In the third and fourth quarters of 
fiscal 2007, we partially offset the inventory write-down discussed above due to recognition of $4.7 million of 
revenue associated with the cash collection and subsequent shipments of this customer’s inventory, which 
resulted in a pre-tax net impact recovery of $4.0 million. 

(cid:2) Asia:

Net sales for fiscal 2008 increased $146.9 million, or 34.4 percent, over fiscal 2007 to $574.1 million.  This 
growth reflected increased net sales to several customers, with the most significant customer growth coming 
from a customer in the medical sector, two customers in the wireline/networking sector and a customer in the 
industrial/commercial sector.  Operating income improved $18.8 million to $59.5 million for fiscal 2008 as 
compared to fiscal 2007.  Operating income improved primarily as a result of higher net sales and operating 
efficiencies resulting from higher production levels.  Increased operating income was partially offset by higher 
fixed manufacturing costs associated with the expansion of facilities and related production equipment, as well 
as additional selling and administrative costs incurred to support growth. 

Net sales for fiscal 2007 increased $111.8 million, or 35.4 percent, over fiscal 2006 to $427.2 million.  This 
growth reflected increased demand from wireline/networking, wireless infrastructure and medical customers as 
well as the transfer of a medical program from the United States.  Operating income improved $12.9 million to 
$40.7 million for fiscal 2007 as compared to fiscal 2006.  Earnings benefited from the incremental net sales 
and the operating efficiencies from the higher production levels. The increase in operating income was

moderated by the increased fixed manufacturing costs associated with the expansion of facilities as well as 
additional selling and administrative costs incurred to support the revenue growth. 

(cid:2) Mexico:

Net sales for fiscal 2008 increased $2.0 million, or 2.6 percent, over fiscal 2007 to $78.3 million.  The net sales 
increase was primarily driven by increased demand from an industrial/commercial customer as well as a new 
wireline/networking customer, offset by decreased demand from two medical customers.  Operating loss 
improved $8.9 million from the prior-year period to a loss of $2.7 million.  The significant improvement from 
fiscal 2007 resulted from a concentrated effort to improve operating results and profitability.  This included the 
replacement of certain key members of the leadership team, headcount reductions to better align the cost 
structure to revenue and assistance from other Plexus resources as needed.  In addition, fiscal 2008 results 
benefited from approximately $2.6 million of revenue from shipping previously written-down inventories and 
the ramping up of production for several new customers of the site.     

Net sales in fiscal 2007 declined by $11.1 million, or 12.7 percent, from fiscal 2006, to $76.3 million.  The 
decline in net sales was related to a wireless infrastructure customer going end-of-life as well as reduced 
demand from an industrial customer that disengaged.  Operating losses widened to $(7.4) million as a result of 
the reduction in net sales and the write-down of $2.6 million of inventory for customers going end-of-life.   

(cid:2)

Europe:

Net sales for fiscal 2008 increased $0.5 million, or 0.7 percent, over fiscal 2007 to $78.3 million.  The change 
in net sales can be attributed to increased demand from two customers offsetting the loss of three customer 
programs that went end-of-life.  Operating income improved $3.6 million to $7.3 million for fiscal 2008 as 
compared to fiscal 2007, primarily as a result of favorable changes in customer mix and the recognition of $1.2 
million of revenue related to the shipment of previously written-down inventories.   

Net sales in fiscal 2007 declined by $26.1 million, or 27.6 percent, from fiscal 2006, to $68.3 million.  The 
revenue decline was attributable to three programs going end of life.  Operating income increased $0.2 million 
or 5.0 percent, to $3.7 million for fiscal 2007 due to the reduced fixed manufacturing and administrative costs 
associated with the closure of the Maldon facility in the second quarter of fiscal 2007 as well as the recognition 
of $0.6 million of revenue related to the cash collection and subsequent shipment of previously written down 
inventory for a financially distressed customer in fiscal 2006.   

For  our  significant  customers,  we  generally  manufacture  products  in  more  than  one  location.    Net  sales  to 
Juniper, our largest customer, occur in the United States and Asia.  Net sales to GE, another significant customer, occur 
in the United States, Asia, Mexico and Europe.  See Note 13 in Notes to Consolidated Financial Statements for certain 
financial information regarding our reportable segments, including a detail of net sales by reportable segment.

FACILITY CLOSURES/EXPANSIONS  

In early fiscal 2009, we purchased a second manufacturing facility in Appleton, Wisconsin.  The new facility 

provides an additional 205,000 square feet of manufacturing space.  We expect to begin manufacturing in this facility in 
the first half of fiscal 2009.  See Note 15 in Notes to Consolidated Financial Statements for a discussion of this 
subsequent event.  

In fiscal 2008, we announced our intention to close our Ayer manufacturing facility and transition the 
customer programs to other facilities in our organization.  The decision was the result of our proactive strategic 
planning process.  After this analysis we determined that the Ayer facility was not strategically aligned with our future 
growth prospects and we could provide greater value to its customers by providing services at other Plexus locations.  
The closure of the facility is expected by March 2009. 

In fiscal 2008, we announced the addition of a new facility in Hangzhou, China.  The leased facility is 
expected to require an investment of approximately $1.5 million for the leasehold and building improvements.  The new 
facility will provide approximately 106,000 square feet of manufacturing space.  We expect to begin manufacturing in 
the new facility during the first quarter of fiscal 2009. 

25

 
 
In fiscal 2006, we announced our intention to close the Maldon manufacturing facility and transition the 
customer programs to our Kelso manufacturing facility.  The decision was the result of reduced customer demand in the 
United Kingdom.  The Maldon facility was closed in the second quarter of fiscal 2007. 

In fiscal 2006, we announced the purchase of a third manufacturing and engineering facility in Penang, 
Malaysia (“Penang”).  The new facility provides an additional 364,000 square feet of manufacturing space.  The initial 
investment for the facility of approximately $11.0 million was completed in the first quarter of fiscal 2007; we began 
manufacturing in the second quarter of fiscal 2007.   

In fiscal 2006, we also announced the expansion of our manufacturing facility in Xiamen, China by 
approximately 60,000 square feet.  This increased our manufacturing capacity at this facility to 120,000 square feet.  
We began manufacturing in the additional space during the second quarter of fiscal 2008.

Net sales for fiscal 2008 increased 19 percent from fiscal 2007.  The net sales growth was due to increased 

demand from customers in each of our five end-market sectors.  Significant increases were noted in our 
wireline/networking, defense/security/aerospace and industrial/commercial sectors.  Increases in the 
wireline/networking sector included increases with our largest customer, Juniper.          

Net sales for fiscal 2007 increased 6 percent from fiscal 2006.  The net sales growth reflected increased 
demand from several customers within the wireline/networking sector, including Juniper, our largest customer.   
Reduced demand from customers within the medical, the industrial/commercial and the defense/security/aerospace 
sectors moderated the overall increase in fiscal 2007 net sales.

Net sales to our customers may vary from time to time depending on the size and timing of customer program 

commencements, terminations, delays, modifications and transitions.  We remain dependent on continued net sales to 
our significant customers, and our customer concentration has remained at or above 60 percent during the year.  We 
generally do not obtain firm, long-term purchase commitments from our customers.  Customers’ forecasts can and do 
change as a result of changes in their end-market demand and other factors.  Any material change in forecasts or orders 
from these major accounts, or other customers, could materially affect our results of operations.  In addition, as our 
percentage of net sales to customers in a specific sector becomes larger relative to other sectors, we become 
increasingly dependent upon economic and business conditions affecting that sector.

For fiscal 2008, gross profit and gross margin were impacted by the following factors: 

increased net sales in all four (U.S., Asian, Mexican and European) reportable segments 
favorable changes in customer mix, including an increase in sales during the first half of fiscal 2008 to the 
large unnamed defense customer, which helped to improve operating efficiencies 
a moderate increase in fixed manufacturing costs in the U.S. and Asian reportable segments primarily due to 
higher salaries and benefits, as a result of additional employees to support net sales growth, and increased 
variable incentive compensation  
an increase in depreciation expense and other fixed manufacturing expenses as a result of our expanded 
facilities in Penang being operational for an entire fiscal year and 
recognition of $3.8 million of net sales in the European and Mexican reportable segments associated with   
shipments of previously written-down inventories. 

For fiscal 2007, gross profit and gross margin were impacted by the following factors:   

the inventory write-downs of $8.5 million in the U.S. and Mexican reportable segments 
recognition of $5.3 million of revenue associated with the cash collection and subsequent shipments of 
previously written down inventory for two financially distressed customers in the U.S. and European 
reportable segments 
$1.3 million of warranty-related expense in the U.S. reportable segment 
an increase in fixed manufacturing costs as a result of our expansion in Penang and 
reduced net sales in the European and Mexican reportable segments, changes in customer mix, price reductions 
and increased depreciation expense, all of which unfavorably impacted gross margin.

Gross margin reflects 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 resulting from the transition of new programs, product life 
cycles, sales volumes, price reductions, 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’ 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 margin and net sales. Although we focus on maintaining gross margin, 
there can be no assurance that gross margin will not decrease in future periods.   

Design work performed by us is not our proprietary property and all costs incurred with this work are generally 
considered reimbursable by our customers.  We do not track research and development costs that are not reimbursed by 
our customers and we consider these amounts immaterial.

The dollar increase in S&A for fiscal 2008 was due to increased salaries and benefits, reflecting wage 
increases, additional headcount to augment business development activities and additional expense for variable 
incentive compensation and stock-based compensation expense.  Variable incentive compensation increased $5.5 
million over the prior-year period as a result of strong financial performance compared to incentive plan targets.       

The dollar increase in S&A for fiscal 2007 was related to several factors that impacted compensation expense.  

We added additional headcount to augment business development activities.  In addition, we were impacted by wage 
increases as well as incremental stock-based compensation of $2.2 million in fiscal 2007.  Offsetting these increases 
was variable incentive compensation, which decreased by $4.8 million in fiscal 2007 from fiscal 2006.  The decrease in 
S&A as a percent of net sales was due to a 6 percent increase in net sales in fiscal 2007 over fiscal 2006.

The restructuring and impairment costs were associated with various reportable segments. Such costs were not 

allocated to our reportable segments, as management excludes such costs when assessing the performance of the 
reportable segments. See Note 13 in Notes to Consolidated Financial Statements for certain financial information 
regarding our reportable segments, including a summary of restructuring and impairment costs by reportable segment. 

Fiscal 2008 restructuring and asset impairment costs: For fiscal 2008, we recorded pre-tax restructuring and 

asset impairment costs of $2.1 million, related to the announcement of the closure of our Ayer facility and the reduction 
of our workforce in Juarez.  The details of these fiscal 2008 restructuring actions are listed below. 

Ayer Facility Closure:  During the fourth quarter of fiscal 2008, we announced our intention to close our Ayer 
facility.  In fiscal 2008, we recorded pre-tax restructuring charges of $1.9 million, related to severance for 170 impacted 
employees and costs to retain certain employees.  In addition to the costs in fiscal 2008, approximately $0.4 million of 
costs related to the disposal of certain assets and costs to exit the leased facility are expected to be incurred through the 
second fiscal quarter of 2009.       

Other Restructuring Costs.  In fiscal 2008, we recorded pre-tax restructuring costs of $0.2 million related to 

severance at our Juarez facility.  The Juarez workforce reductions affected approximately 20 employees.  

Fiscal 2007 restructuring and asset impairment costs: For fiscal 2007, we recorded pre-tax restructuring and 

asset impairment costs of $1.8 million, related to the closure of our Maldon facility and the reduction of our workforces 
in Juarez and Kelso.  The details of these fiscal 2007 restructuring actions are listed below:

Maldon Facility Closure:  The Maldon facility ceased production on December 12, 2006, and the closure 

resulted in a workforce reduction of 75 employees at a cost of $0.5 million.  During the second fiscal quarter of 2007, 
the Company sold the Maldon facility for $4.4 million and recorded a $0.4 million gain on this transaction.    

Other Restructuring Costs.  In fiscal 2007, we recorded pre-tax restructuring costs of $1.0 million related to 

severance at our Juarez facility. The Juarez workforce reductions affected approximately 125 employees.  During fiscal 
2007, we also recorded pre-tax restructuring costs of $0.3 million related to severance at our Kelso facility.  The Kelso 
workforce reductions affected approximately 10 employees.   

Fiscal 2006 restructuring and asset impairment costs: For fiscal 2006, we recorded pre-tax restructuring and 

asset impairment costs of $1.0 million, related to the decisions to initially convert and then ultimately close our Maldon 
facility and to reduce the workforce in Juarez.  For fiscal 2006, these restructuring costs were offset by favorable 
adjustments in lease obligations of $0.8 million, as a result of entering into lease termination or sublease agreements for 
three of our previously closed facilities in the Bothell and Seattle, Washington area, as well as favorable adjustments of 
$0.2 million, related to other restructuring accruals. The details of these fiscal 2006 restructuring actions are listed 
below:  

Maldon Facility Closure:   We announced the decision to close our Maldon facility in July 2006.  For fiscal 

2006, we recorded $0.5 million for severance and asset impairments related to the closure of the Maldon facility.  This 
restructuring affected 75 employees.     

Maldon Facility Conversion:   In the third quarter of fiscal 2005, we announced a planned workforce reduction 

at the Maldon facility to convert this manufacturing facility to a fulfillment, service and repair facility.  As a result of 
this planned conversion, we recorded expenses of $0.2 million for retention costs (severance cost) for fiscal 2006 
related to the workforce reduction as part of the Maldon facility conversion. This restructuring affected 43 employees.   

Other Restructuring Costs.  In fiscal 2006, we recorded pre-tax restructuring costs of $0.3 million related to 

severance at our Juarez facility. The Juarez workforce reductions affected approximately 46 employees.

Other income (expense) for fiscal 2008 decreased $5.0 million, to $0.2 million of expense from $4.8 million of 

income in fiscal 2007.  This was due to increased interest expense of $3.4 million, primarily related to servicing the 
$150 million term loan drawn in April 2008, and reduced interest income of $1.4 million, which was due to reduced 
effective interest rates and lower average cash balances during fiscal 2008. Miscellaneous income (expense) fluctuated 
unfavorably due primarily to foreign currency translation adjustments.

Other income (expense) for fiscal 2007 increased $1.7 million, to $4.8 million of income, over fiscal 2006 due 

to increased interest income related to higher average cash balances as well as a higher effective interest rate during 
fiscal 2007.  Interest expense remained comparable between fiscal years. Miscellaneous income (expense) fluctuated 
unfavorably due primarily to foreign currency translation adjustments.

The decrease in our effective tax rate from fiscal 2007 to fiscal 2008 is primarily due to a higher proportion of 
income in Malaysia and China where we currently have reduced tax rates due to tax holidays that extend through 2019 
and 2013, respectively.   

Our effective tax rate increased in fiscal 2007 from fiscal 2006 because we recorded a tax provision associated 

with U.S. pre-tax income in fiscal 2007 whereas no such tax provision was required for the prior fiscal years.  During 
fiscal 2006, we recorded minimal income tax expense as a result of the establishment in fiscal 2004 of a full valuation 
allowance on U.S. deferred income tax assets (see further discussion below) and increased income in Malaysia and 
China, which benefit from tax holidays, and reduced pre-tax income in the United Kingdom.  In the fourth quarter of 
fiscal 2006, we reversed $17.7 million of the previously recorded valuation allowance as a credit to income tax.  

Under Statement of Financial Accounting Standards (“SFAS”) No. 109, “Accounting for Income Taxes” 

(“SFAS No. 109”), historical and projected financial results (along with any other positive or negative evidence) should 
be considered when assessing our ability to generate future taxable income and realize any net deferred income tax 
assets.  Our U.S. operations generated significant pre-tax income in fiscal 2006.  Based on our fiscal 2006 pre-tax 
income and an assessment of expected future profitability in the U.S., we concluded that it was more likely than not that 
the tax benefits of our cumulative net deferred income tax assets in the U.S. would be utilized in the future.  Therefore, 
we reversed $17.7 million of the valuation allowance as noted above.   

As a result of using the with-and-without method under SFAS No. 123(R), “Share-Based Payment” (“SFAS 

No. 123(R)”), we recorded a valuation allowance against the amount of net operating loss and credit carryforwards 
related to tax deductions in excess of compensation expense for stock options until such time as the related deductions 
actually reduce income taxes payable.  We had recorded a valuation allowance of $16.7 million in fiscal 2006 against 
our net operating loss carryforwards as of September 30, 2006.  During fiscal 2007, we realized a reduction of our 
income taxes payable for all of our federal net operating loss carryforwards and a portion of our state net operating loss 
carryforwards.  Consequently, we reversed approximately $15.0 million of this valuation allowance with a 
corresponding credit to additional paid in capital.  During fiscal 2008, we released an additional $0.6 million to 
additional paid in capital due to the usage of our state net operating loss carryforwards.  As a result, we had a remaining 
valuation allowance of $1.1 million related to tax deductions associated with stock-based compensation as of 
September 27, 2008.    

In addition, there was a remaining valuation allowance of $1.5 million as of September 27, 2008, related to 

various state deferred income tax assets for which utilization was uncertain due to a lack of sustained profitability and 
limited carryforward periods in those states. 

We currently expect the annual effective tax rate for fiscal 2009 to be approximately 15 percent.  China and 

Mexico have passed new tax laws that were effective on January 1, 2008.  Those new laws may result in higher tax 
rates on our operations in those countries during fiscal 2009 or in the future. 

Net Income.  As a result of the above factors, our net income increased by $18.4 million, or 28.0 percent, in 

fiscal 2008 compared to fiscal 2007.  Diluted earnings per share increased 36.2 percent.  The per share earnings 
increased at a higher rate than net income due to the effects of our stock repurchase program, which was conducted 
during fiscal 2008.  Net income decreased by $34.3 million, or 34.3 percent, in fiscal 2007 compared to fiscal 2006; 
diluted earnings per share decreased 34.4 percent.      

LIQUIDITY AND CAPITAL RESOURCES 

Cash flows provided by operating activities were $64.2 million for fiscal 2008, compared to cash flows 
provided by operating activities of $38.5 million and $83.1 million for fiscal 2007 and 2006, respectively.  During fiscal 
2008, cash provided by operating activities was primarily provided by earnings (after adjusting for the non-cash effects 

30

 
 
of depreciation and amortization expense, deferred income taxes and stock-based compensation expense).  These 
positive cash flow effects were offset, in part, by higher accounts receivable and inventory to support increased 
customer demand in the first quarter of fiscal 2009.   

Our annualized days sales outstanding in accounts receivable for fiscal 2008 decreased from 54 days in fiscal 

2007 to 50 days in fiscal 2008, primarily as a result of stronger cash collections. 

Our inventory turns decreased from 5.5 turns for fiscal 2007 to 5.3 turns for fiscal 2008.  Inventories increased 

by $64.4 million from September 29, 2007, primarily as a result of increased finished goods to enhance flexibility and 
support inventory models such as DOF for various customers.    

Cash flows used in investing activities totaled $1.1 million for fiscal 2008.  The primary investments included 

$54.3 million for purchases of property, plant and equipment, offset by $53.0 million of net sales of short-term 
securities.  Fiscal 2008 purchases of property, plant and equipment included $27.6 million, $22.3 million, $2.9 million 
and $1.5 million related to our Asian, U.S., Mexican and European reportable segments, respectively.   

We utilized available cash and operating cash flows as the principal sources for funding our operating 

requirements during fiscal 2008.  Our actual level of capital expenditures for fiscal 2009 will depend on anticipated 
demand, but we currently expect to spend in the range of $70 million to $75 million.  

Cash flows utilized by financing activities, totaling $49.6 million for fiscal 2008, primarily represent the 

purchases of common stock related to our share repurchase program, offset by proceeds from the issuance of a $150 
million term loan in April 2008.   

On February 25, 2008, Plexus adopted a common stock buyback program that permitted it to acquire shares of 

its common stock for an amount up to $200 million.  The authorized stock repurchase program consisted of a $100 
million accelerated stock repurchase (“ASR”) program and an additional $100 million of open market purchases. 

During the second quarter of fiscal 2008, under our ASR plan, we purchased a total of 3.8 million shares 

classified as treasury stock at a volume-weighted average price of $26.51 per share.  In addition to the ASR plan 
purchases, the Company repurchased 3.6 million shares at a volume-weighted average price of $27.25 per share in the 
open market during the third and fourth fiscal quarters of 2008.  Therefore, the Company completed the $200 million 
share repurchase program with a total purchase of 7.4 million shares at a volume-weighted average price of $26.87 per 
share.  See Note 7 to the Consolidated Financial Statements for further information regarding our share repurchase 
program. 

On April 4, 2008, we entered into a second amended and restated credit agreement (the “Amended Credit 

Facility”) with a group of banks which allows us to borrow $150 million in term loans and $100 million in revolving 
loans.  The $150 million in term loans was immediately funded and the $100 million revolving credit facility is 
currently available.  The Amended Credit Facility is unsecured and may be increased by an additional $100 million (the 
“accordion feature”) if we have not previously terminated all or any portion of the Amended Credit Facility, there is no 
event of default existing under the credit agreement and both we and the administrative agent consent to the increase.  
The Amended Credit Facility expires on April 4, 2013.  Borrowings under the Amended Credit Facility may be either 
through term loans or revolving or swing loans or letter of credit obligations.  As of November 10, 2008, we have term 
loan borrowings of $142.5 million outstanding and no revolving borrowings under the Amended Credit Facility. 

The Amended Credit Facility amended and restated our prior revolving credit facility (“Revolving Credit 

Facility”) with a group of banks that allowed us to borrow up to $200 million of which $100 million was committed.  
The Revolving Credit Facility was due to expire on January 12, 2012 and was also unsecured.  It also contained other 
terms and financial conditions, which were substantially similar to those under the Amended Credit Facility. 

The Amended Credit Facility contains certain financial covenants, which include a maximum total leverage 

ratio, maximum value of fixed rentals and operating lease obligations, a minimum interest coverage ratio and a 
minimum net worth test, all as defined in the agreement. As of September 27, 2008, we were in compliance with all 
debt covenants.  If we incur an event of default, as defined in the Amended Credit Facility (including any failure to 
comply with a financial covenant), the group of banks has the right to terminate the remaining Revolving Credit Facility 
and all other obligations, and demand immediate repayment of all outstanding sums (principal and accrued interest).  
Interest on borrowing varies depending upon our then-current total leverage ratio; as of September 27, 2008, the 
Company could elect to pay interest at a defined base rate or the LIBOR rate plus 1.25%.  Rates would increase upon 
negative changes in specified Company financial metrics and would decrease upon reduction in the current total 

31

 
 
leverage ratio to no less than LIBOR plus 1.00%.  We are also required to pay an annual commitment fee on the unused 
credit commitment based on our leverage ratio; the current fee is 0.30 percent.  Unless the accordion feature is 
exercised, this fee applies only to the initial $100 million of availability (excluding the $150 million of term 
borrowings).  Origination fees and expenses associated with the Amended Credit Facility totaled approximately $1.3 
million and have been deferred.  These origination fees and expenses will be amortized over the five-year term of the 
Amended Credit Facility.  Quarterly principal repayments on the term loan of $3.75 million each began June 30, 2008, 
and end on April 4, 2013, with a final balloon repayment of $75.0 million. 

The Amended Credit Facility allows for the future payment of cash dividends or the future repurchases of shares 

provided that no event of default (including any failure to comply with a financial covenant) is existing at the time of, or 
would be caused by, the dividend payment or the share repurchases. 

As of September 27, 2008, we held $2.0 million of auction rate securities, which were classified as long-term 

investments and whose underlying assets were in guaranteed student loans backed by a U. S. government agency.  
Auction rate securities are adjustable rate debt instruments whose interest rates are reset every 7 to 35 days through an 
auction process, with underlying securities that have original contractual maturities greater than 10 years. Auctions for 
these investments failed during the second, third and fourth quarters of fiscal 2008 and there is no assurance that future 
auctions on these securities will succeed.  

An auction failure means that the parties wishing to sell their securities could not do so. As a result, our ability 

to liquidate and fully recover the carrying value of our adjustable rate securities in the near term may be limited or not 
exist. These developments have resulted in the classification of these securities as long-term investments in our 
consolidated financial statements.  If the issuers of these adjustable rate securities are unable to successfully close future 
auctions or their credit quality deteriorates, we may in the future be required to record an impairment charge on these 
investments. We may be required to wait until market stability is restored for these instruments or until the final 
maturity of the underlying notes to realize our investments’ recorded value. 

Based on current expectations, we believe that our projected cash flows from operations, available cash and 

short-term investments, the Amended Credit Facility, and our leasing capabilities should be sufficient to meet our 
working capital and fixed capital requirements through fiscal 2009.  Although net sales growth anticipated for fiscal 
2009 is expected to increase our working capital needs, we currently do not anticipate having to use our Amended 
Credit Facility to finance this growth.  If our future financing needs increase, we may need to arrange additional debt or 
equity financing.  Accordingly, we evaluate and consider from time to time various financing alternatives to supplement 
our financial resources.  However, particularly due to the current instability of the credit and financial markets, we 
cannot be certain that we will be able to make any such arrangements on acceptable terms. 

We anticipate using our earnings to support the future growth of our business.  We have not paid cash 

dividends in the past and do not anticipate paying them in the foreseeable future.  We may in the future consider 
repurchasing some of our outstanding shares, although at this time no board authorization is in place for additional 
purchases.  The future payment of cash dividends or the future repurchase of shares would be dependent upon being 
compliant with the financial covenants existing under the Amended Credit Facility.  These covenants require that there 
be no event of default existing at the time of, or be caused by, a dividend payment or share repurchase.

As of April 4, 2008, we entered into an amended and restated credit agreement and immediately funded a term 
loan for $150 million.  As of September 27, 2008, the outstanding balance was $146.3 million.  See Note 4 in 
Notes to Consolidated Financial Statements for further information. 

As of September 27, 2008, purchase obligations consisted of purchases of inventory and equipment in the 
ordinary course of business. 

As of September 27, 2008, other long-term obligations on the balance sheet included deferred compensation 
obligations to certain of our former and current executive officers and other key employees, and an asset 
retirement obligation related to FASB Interpretation No. 47, “Accounting for Conditional Asset Retirement 
Obligations.”  We have excluded from the above table the impact of approximately $5.0 million related to 
unrecognized income tax benefits as of September 27, 2008, due to the adoption of FASB interpretation No. 
48, “Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement No. 109.”  The 
Company cannot make reliable estimates of the future cash flows by period related to this obligation. 

As of September 27, 2008, other long-term obligations not on the balance sheet consisted of a commitment for 
salary continuation in the event employment of one executive officer of the Company is terminated without 
cause.  We did not have, and were not subject to, any lines of credit, standby letters of credit, guarantees, 
standby repurchase obligations, other off-balance sheet arrangements or other commercial commitments that 
were material.   

DISCLOSURE ABOUT CRITICAL ACCOUNTING POLICIES

Our accounting policies are disclosed in Note 1 of Notes to the Consolidated Financial Statements.  During 
fiscal 2008, there were no material changes to these policies.  Our more critical accounting policies are noted below: 

Stock-Based Compensation - Effective October 2, 2005, we adopted SFAS No. 123(R), “Share-Based 
Payment” , which revised SFAS No. 123, “Accounting for Stock-Based Compensation” and supersedes APB Opinion 
No. 25, “Accounting for Stock Issued to Employees”.  SFAS No. 123(R) requires all share-based payments to 
employees, including grants of employee stock options, to be measured at fair value and expensed in the consolidated 
statement of operations over the service period (generally the vesting period) of the grant. Upon adoption, we 
transitioned to SFAS No. 123(R) using the modified prospective application, under which compensation expense is 
only recognized in the consolidated statements of operations beginning with the first period that SFAS No. 123(R) is 
effective and continuing to be expensed thereafter. Prior periods’ stock-based compensation expense is still presented 
on a pro forma basis.  We continue to use the Black-Scholes valuation model to value stock options.  See Note 1 in 
Notes to Consolidated Financial Statements for further information.

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 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 revenue and 
cash flow projections.  Circumstances that may lead to impairment of property, plant and equipment include reduced 
expectations for future performance or industry demand and possible further restructurings.   

Intangible Assets – Under SFAS No. 142, “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, and recognize any related losses when incurred.  We perform goodwill 
impairment tests annually during the third quarter of each fiscal year or more frequently if an event or circumstance 
indicates that an impairment has occurred.   

We measure the recoverability of goodwill under the annual impairment test by comparing a 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. 

Revenue – Net sales from manufacturing services are recognized when the product has been shipped, the risk 

of ownership has transferred to the customer, the price to the buyer is fixed or determinable, and recoverability is 
reasonably assured.  This point depends on contractual terms and generally occurs upon shipment of the goods from 
Plexus.  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.   

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 a percentage-of-completion method; any 
losses are recognized when anticipated.  

Sales are recorded net of estimated returns of manufactured product based on management’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, if applicable.  The corresponding shipping and handling costs are 
included in cost of sales.  

Derivatives and Hedging Activities – All derivatives are recognized on the balance sheet at their estimated fair 

value.  On the date a derivative contract is entered into, the Company designates the derivative as a hedge of a 
recognized asset or liability (a “fair value” hedge), a hedge of a forecasted transaction or of the variability of cash flows 
to be received or paid related to a recognized asset or liability (a “cash flow” hedge), or a hedge of the net investment in 
a foreign operation. The Company does not enter into derivatives for speculative purposes. Changes in the fair value of 
a derivative that qualify as a fair value hedge are recorded in earnings along with the gain or loss on the hedged asset or 
liability. Changes in the fair value of a derivative that qualifies as a cash flow hedge are recorded in “Accumulated 
other comprehensive income”, until earnings are affected by the variability of cash flows. Changes in the fair value of a 
derivative used to hedge the net investment in a foreign operation are recorded in the “Accumulated other 
comprehensive income” accounts within shareholders’ equity. 

In June 2008, the Company entered into three interest rate swap contracts related to the $150 million in term 
loans under the Amended Credit Facility that have a total notional value of $150 million and mature on April 4, 2013. 
These interest rate swap contracts will pay the Company variable interest at the three month LIBOR rate, and the 
Company will pay the counterparties a fixed interest rate.  The fixed interest rates for each of these contracts are 
4.415%, 4.490% and 4.435%, respectively.  These interest rate swap contracts were entered into to convert $150 million 
of the variable rate term loan under the Amended Credit Facility into fixed rate debt. Based on the terms of the interest 
rate swap contracts and the underlying debt, these interest rate contracts were determined to be effective, and thus 
qualify as a cash flow hedge. As such, any changes in the fair value of these interest rate swaps are recorded in 
“Accumulated other comprehensive income” on the accompanying Consolidated Balance Sheets until earnings are 
affected by the variability of cash flows. Any gain or loss on the derivatives will be recorded in the income statement in 

34

“Interest expense”.  The total fair value of these interest rate swap contracts is $3.0 million at September 27, 2008, and 
the Company has recorded this amount in “Other” current liabilities and “Other liabilities” in the accompanying 
Consolidated Balance Sheets.

Income Taxes – Deferred income taxes are provided for differences between the bases of assets and liabilities 

for financial and income tax reporting purposes.  We 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 taxable 
income. Although our net deferred income tax assets as of September 27, 2008 still reflect a $1.5 million valuation 
allowance against certain deferred income tax assets, we may be able to utilize these deferred income tax assets to offset 
future taxable income in certain states.  We also have a remaining valuation allowance of $1.1 million related to tax 
deductions associated with stock-based compensation as of September 27, 2008.   

NEW ACCOUNTING PRONOUNCEMENTS 

In March 2008, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 161, “Disclosures 

about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133” (“SFAS No. 161”).  
This statement changes the disclosure requirements for derivative instruments and hedging activities.  SFAS No. 161 
requires enhanced disclosures about (a) how and why an entity uses derivative instruments, (b) how derivative 
instruments and related hedged items are accounted for under “Accounting for Derivative Instruments and Hedging 
Activities” (“SFAS No. 133”), and its related interpretations, and (c) how derivative instruments and related hedged 
items affect an entity’s financial position, financial performance, and cash flows.  This statement is effective for 
financial statements issued for fiscal years and interim periods beginning after November 15, 2008.  The Company is 
currently assessing the impact of SFAS No. 161 on its consolidated results of operations, financial position and cash 
flows. 

In December 2007, the FASB issued SFAS No. 160, “Non-controlling Interests in Consolidated Financial 

Statements - an amendment to ARB No. 51” (“SFAS No. 160”).  SFAS No. 160 will change the accounting and 
reporting for minority interests, which will now be termed “non-controlling interests.” SFAS No. 160 requires non-
controlling interests to be presented as a separate component of equity and requires the amount of net income 
attributable to the parent and to the non-controlling interest to be separately identified on the consolidated statement of 
operations. SFAS No. 160 is effective for fiscal years beginning on or after December 15, 2008. The Company is 
currently assessing the impact of SFAS No. 160 on its consolidated results of operations, financial position and cash 
flows. 

In December 2007, the FASB issued Statement of Financial Accounting Standards No. 141R, “Business 

Combinations” (“SFAS No. 141R”).  SFAS No. 141R states that all business combinations (whether full, partial or step 
acquisitions) will result in all assets and liabilities of an acquired business being recorded at their fair values.  Certain 
forms of contingent consideration and certain acquired contingencies will be recorded at fair value at the acquisition 
date.  SFAS No. 141R also states acquisition costs will generally be expensed as incurred and restructuring costs will be 
expensed in periods after the acquisition date.  This statement is effective for financial statements issued for fiscal years 
beginning after December 15, 2008, and will impact the Company’s accounting for future acquisitions. 

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial 
Liabilities – Including an Amendment of FASB Statement No. 115” (“SFAS No. 159”).  This standard permits an entity 
to choose to measure many financial instruments and certain other items at fair value.  The fair value option permits a 
company to choose to measure eligible items at specified election dates.  A company will report unrealized gains and 
losses on items for which the fair value option has been elected in earnings after adoption.  The effective date for SFAS 
No. 159 is as of the beginning of fiscal years that start subsequent to November 15, 2007.  The Company is currently 
assessing the impact of SFAS No. 159 on its consolidated results of operations, financial position and cash flows. 

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS No. 157”).  This 

standard defines fair value, establishes a framework for measuring fair value in generally accepted accounting 
principles and establishes a hierarchy that categorizes and prioritizes the sources to be used to estimate fair value. SFAS 
No. 157 also expands financial statement disclosures about fair value measurements.  On February 12, 2008, the FASB 
issued FASB Staff Position (“FSP”) 157-2 (“FSP 157-2”) which delays the effective date of SFAS No. 157 for one 
year, for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in 
the financial statements on a recurring basis (at least annually).  FAS No. 157 and FSP 157-2 are effective for financial 
statements issued for fiscal years beginning after November 15, 2007.  The Company is currently assessing the impact 
of SFAS No. 157 and FSP 157-2 on its consolidated results of operations, financial position and cash flows.

ITEM 7A. 

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

We are exposed to market risk from changes in foreign exchange and interest rates.  We selectively use 

financial instruments 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.  Historically, we have used 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 27, 2008, we had no foreign currency contracts 
outstanding.   

Our percentages of transactions denominated in currencies other than the U.S. dollar for the indicated periods 

were as follows: 

Net Sales 
Total Costs 

Interest Rate Risk 

Fiscal year 
2007 
5% 
11% 

2006 
7% 
12% 

2008 
4% 
11% 

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 and have 
entered into interest rate swaps for $150 million in term loans as described in Note 5 in Notes to Consolidated Financial 
Statements.     

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 Amended Credit Facility under which we borrowed 
$150 million on April 4, 2008.  Through the use of interest rate swaps, as described above, we have fixed the basis on 
which we pay interest, thus eliminating much of our interest rate risk.  A 10 percent change in the weighted average 
interest rate on our average long-term borrowings would have had only a nominal impact on net interest expense.   

Auction Rate Securities 

As of September 27, 2008, we held $2.0 million of auction rate securities, which were classified as long-term 

other assets.  On February 21, 2008, we were unable to liquidate these investments, whose underlying assets were in 
guaranteed student loans backed by a U.S. government agency.  We have the ability and intent to hold these securities 
until a successful auction occurs and these securities are liquidated at par value.  At this time, we believe that the 
securities will eventually be recovered.  However, we may be required to hold these securities until market stability is 
restored for these instruments or final maturity of the underlying notes to realize our investments’ recorded value.  
Accordingly, we have classified these securities as long-term other assets.

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 a timely basis.  The Company’s principal executive officer 
and principal financial officer have reviewed and evaluated, with the participation of the Company’s management, the 
Company’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”) as of the end of the period covered by this report (the 
“Evaluation Date”).  Based on such evaluation, the chief executive officer and chief financial officer have concluded 
that, as of the Evaluation Date, the Company’s disclosure controls and procedures are effective (a) in recording, 
processing, summarizing and reporting, on a timely basis, information required to be disclosed by the Company in the 
reports the Company files or submits under the Exchange Act, and (b) are accumulated and communicated to the 
Company’s management, including the chief executive officer and chief financial officer, as appropriate to allow timely 
decisions regarding required disclosure. 

Management’s Annual Report on Internal Control Over Financial Reporting: Management of the Company is 

responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined 
in Exchange Act Rules 13a-15(f) and 15d-15(f).  Management of the Company, including its chief executive officer and 
chief financial officer, has assessed the effectiveness of its internal control over financial reporting as of September 27, 
2008, 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 September 27, 2008, the Company’s internal control over 
financial reporting was effective. 

The independent registered public accounting firm of PricewaterhouseCoopers LLP has audited the 
Company’s internal control over financial reporting as of September 27, 2008, as stated in their report included herein 
on page 41. 

Changes in Internal Control Over Financial Reporting: There have been no changes in the Company’s 

internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that 
occurred during the Company’s most recent fiscal quarter that have materially affected, or are reasonably likely to 
materially affect, the Company’s internal control over financial reporting. 

Limitations on the Effectiveness of Controls: Our management, including our chief executive officer and chief 
financial officer, does not expect that our disclosure controls and internal controls will prevent all errors and all fraud. A 
control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that 
the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are 
resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent 
limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and 
instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that 
judgments in decision-making can be faulty, and that breakdowns can occur because of simple errors or mistakes. 
Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, 
or by management override of the control. The design of any system of controls also is based in part upon certain 
assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in 
achieving its stated goals under all potential future conditions; over time, a control may become inadequate because of 
changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the 
inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be 
detected.

Notwithstanding the foregoing limitations on the effectiveness of controls, we have nonetheless reached the 

conclusions set forth above on our disclosure controls and procedures and our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm 

To the Shareholders 
and Board of Directors 
of Plexus Corp: 

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 27, 2008 and September 29, 2007, and 
the results of their operations and their cash flows for each of the three years in the period ended September 27, 2008 in 
conformity with accounting principles generally accepted in the United States of America.  In addition, in our opinion, 
the financial statement schedule listed in the accompanying index presents fairly, in all material respects, the 
information set forth therein when read in conjunction with the related consolidated financial statements.  Also in our 
opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of 
September 27, 2008, based on criteria established in Internal Control - Integrated Framework issued by the Committee 
of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for 
these financial statements and financial statement schedules, for maintaining effective internal control over financial 
reporting and for its assessment of the effectiveness of internal control over financial reporting, included in 
Management's Annual Report on Internal Control Over Financial Reporting appearing under Item 9A. Our 
responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the 
Company's internal control over financial reporting based on our integrated audits.  We conducted our audits in 
accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards 
require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are 
free of material misstatement and whether effective internal control over financial reporting was maintained in all 
material respects.  Our audits of the financial statements included 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.  Our audit of internal control over 
financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk 
that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control 
based on the assessed risk.  Our audits also included performing such other procedures as we considered necessary in 
the circumstances. We believe that our audits provide a reasonable basis for our opinions. 

As discussed in Note 1, the Company adopted FASB Interpretation No. 48, "Accounting for Uncertainty in Income 
Taxes - an interpretation of FASB Statement No. 109" ("FIN 48"), effective at the beginning of fiscal year 2008.  

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 
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.

Notes to Consolidated Financial Statements

Description of Business and Significant Accounting Policies

Description of Business:  Plexus Corp. and its subsidiaries (together “Plexus” or the “Company”) 

participate in the Electronic Manufacturing Services (“EMS”) industry.  As a contract manufacturer, we 
provide product realization services to original equipment manufacturers (“OEMs”) and other technology 
companies in the wireline/networking, wireless infrastructure, medical, industrial/commercial, and 
defense/security/aerospace market sectors.  The Company provides advanced electronics design, 
manufacturing and testing services to our customers with a focus on complex and global fulfillment solutions, 
high technology manufacturing and test services, and high reliability products.  The Company offers our 
customers the ability to outsource all stages of product realization, including development and design; 
materials sourcing, procurement and management; prototyping and new product introduction; testing; 
manufacturing; product configuration; logistics and test/repair. 

The Company provides most of our contract manufacturing services on a turnkey basis, which 

means that we procure some or all of the materials required for product assembly.  The Company provides 
some services on a consignment basis, which means that the customer supplies the necessary materials and 
the Company provides the labor and other services required for product assembly.  Turnkey services require 
material procurement and warehousing, in addition to manufacturing, and involve greater resource 
investments than consignment services.  Other than certain test equipment and software used for internal 
manufacturing, the Company does not design or manufacture our own proprietary products. 

Consolidation 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.  All significant intercompany transactions have been eliminated. 

The Company’s fiscal year ends on the Saturday closest to September 30.  The Company also uses a 
“4-4-5” weekly accounting system for the interim periods in each quarter.  Each quarter, therefore, ends on a 
Saturday at the end of the 4-4-5 period.  The accounting years for fiscal 2008, 2007 and 2006 each included 
364 days.  Periodically, an additional week must be added to the fiscal year to re-align with the Saturday 
closest to September 30. Fiscal 2009 will include this additional week and the fiscal year-end will be October 
3, 2009. Therefore the accounting year for 2009 will include 371 days.  The additional week will be added to 
our first quarter which will include 98 days and end on January 3, 2009. 

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.”  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 2008, 2007 and 2006, 
unrealized or realized gains and losses were not material.   

As of September 27, 2008 and September 29, 2007, cash and cash equivalents included the 

following securities (in thousands):

Plexus Corp. 
Notes to Consolidated Financial Statements - Continued

Short-term investments as of September 29, 2007 consisted of state and municipal auction rate 

securities.   

Inventories: Inventories are valued at the lower of cost or market.  Cost is determined by the first-in, 

first-out (FIFO) method.  Valuing inventories at the lower of cost or market requires the use of estimates and 
judgment.  Customers may cancel their orders, change production quantities or delay production for a number 
of reasons that are beyond the Company’s control.  Any of these, or certain additional actions, could impact 
the valuation of inventory.  Any actions taken by the Company’s customers that could impact the value of its 
inventory are considered when determining the lower of cost or market valuations. 

Customer deposits primarily include amounts received, per contractual terms, for obsolete and 

excess inventory.     

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: 

Buildings and improvements 
Machinery and equipment 
Computer hardware and software 

15-50 years 
 3-10 years 
 2-10 years 

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”) 98-1, 

“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.  

Expenditures for maintenance and repairs are expensed as incurred. 

Goodwill and Other Intangible Assets:  The Company adopted Statement of Financial Accounting 

Standards (“SFAS”) No. 142, “Goodwill and Other Intangible Assets” (“SFAS No. 142”) effective October 1, 
2002. Under SFAS No. 142, 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, and recognizes any 
related losses when incurred.  Recoverability of goodwill is measured at the reporting unit level.  

The Company is required to perform goodwill impairment tests at least annually, for which the 
Company selected the third quarter of each fiscal year, or whenever events or changes in circumstances 
indicate that the carrying value may not be recoverable. 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.

For the years ended September 27, 2008 and September 29, 2007 changes in the carrying amount of 

goodwill for the European reportable segment were as follows (in thousands):

               (787)

  $ 

7,275

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.  Intangible asset amortization expense 
was nominal for fiscal 2008, 2007 and 2006.  The Company has no intangibles, except goodwill, that are not 
subject to amortization.  During fiscal 2008, there were no additions to intangible assets.   

Impairment of Long-Lived Assets: 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 reduced expectations 
for future performance or industry demand and possible further restructurings.   

Revenue Recognition:  Net sales from manufacturing services are recognized when the product has 

been shipped, the risk of ownership has transferred to the customer, the price to the buyer is fixed or 
determinable, and recoverability is reasonably assured.  This point depends on contractual terms and 
generally occurs upon shipment of the goods from Plexus.  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 with a duration of twelve months or less, are recognized as costs are incurred utilizing a 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 five percent 
of total sales in fiscal 2008, 2007 and 2006. 

Sales are recorded net of estimated returns of manufactured products based on management’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 closures, including leased facilities that will be 
abandoned (and subleased, as applicable), and impairment of equipment.   

Costs associated with a restructuring activity are recorded in accordance with SFAS No. 146, 

“Accounting for Costs Associated with Exit or Disposal Activities” (“SFAS No. 146”).  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, depend on whether employees are required to render service until they are 

48

 
Plexus Corp. 
Notes to Consolidated Financial Statements - Continued

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 Accounting for Postemployment Benefits” (“SFAS 
No. 112”), 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.  For contract termination costs, including costs 
that will continue to be incurred under a contract for its remaining term without economic benefit to the 
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’s estimates and assumptions, the Company may be 
required to revise the estimates of future liabilities, which could result in recording 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 6). Realization of deferred income tax 
assets is dependent on the Company’s ability to generate future taxable income.  The Company records 
windfall tax benefits upon stock option exercises using the with-and-without method. 

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 average 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 our Statements of Operations as a component of miscellaneous other income 
(expense).  Exchange gains (losses) on foreign currency transactions were $(1.7) million, $(1.5) million and 
$0.4 million for the fiscal years ended September 27, 2008, September 29, 2007 and September 30, 2006, 
respectively.

Derivatives:  The Company periodically enters into derivative contracts such as foreign currency 

forward, call and put contracts, which are designated as cash-flow hedges.  All derivatives are recognized on 
the balance sheet at their estimated fair value.  On the date a derivative contract is entered into, the Company 
designates the derivative as a hedge of a recognized asset or liability (a “fair value” hedge), a hedge of a 
forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or 
liability (a “cash flow” hedge), or a hedge of the net investment in a foreign operation. The Company does 
not enter into derivatives for speculative purposes. Changes in the fair value of a derivative that qualify as a 
fair value hedge are recorded in earnings along with the gain or loss on the hedged asset or liability. Changes 
in the fair value of a derivative that qualifies as a cash flow hedge are recorded in “Accumulated other 
comprehensive income”, until earnings are affected by the variability of cash flows. Changes in the fair value 
of a derivative used to hedge the net investment in a foreign operation are recorded in the “Accumulated other 
comprehensive income” accounts within shareholders’ equity.  Our interest rate swaps are treated as cash 
flow hedges and therefore $(1.7) million for 2008 was recorded in “Accumulated other comprehensive 
income.”  These amounts were not material during fiscal 2007 or 2006.  

49

Plexus Corp. 
Notes to Consolidated Financial Statements - Continued

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 and restricted stock awards, unless 
such options are antidilutive.  

Stock-based Compensation:  Effective October 2, 2005, the Company adopted SFAS No. 123(R), 

“Share-Based Payment” (“SFAS No. 123(R)”), which revised SFAS No. 123, “Accounting for Stock-Based 
Compensation” and supersedes Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued 
to Employees.”  SFAS No. 123(R) requires all share-based payments to employees, including grants of 
employee stock options, to be measured at fair value and expensed in the consolidated statement of 
operations over the service period (generally the vesting period) of the grant. Upon adoption, the Company 
transitioned to SFAS No. 123(R) using the modified prospective application, under which compensation 
expense is only recognized in the consolidated statements of operations beginning with the first period that 
SFAS No. 123(R) is effective and continuing to be expensed thereafter.   

Comprehensive Income:  The Company has adopted SFAS No. 130, “Reporting Comprehensive 

Income” (“SFAS No. 130”). SFAS No. 130 establishes standards for reporting comprehensive income, which 
it defines as the changes in equity of an enterprise except those resulting from stockholder transactions.  

Accumulated other comprehensive income consists of the following as of September 27, 2008 and 

September 29, 2007 (in thousands):

Conditional Asset Retirement Obligations: In March 2005, the Financial Accounting Standards 

Board (“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.  Upon adoption of FIN 47 in the fourth quarter of fiscal 2006, we 
recorded an increase in property, plant and equipment, net of $0.1 million and recognized an asset retirement 
obligation of $0.6 million.  This resulted in the recognition of a non-cash charge of $0.5 million ($0.5 million 
after-tax, or $0.01 per share) for the year ended September 30, 2006 that was reported as a cumulative effect 
of an accounting change.  The liability is adjusted for any additions or deletions of related property, plant and 
equipment.    

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 were reflected in the 

consolidated financial statements at cost because of the short-term duration of these instruments.  Accounts 
receivable were reflected at net realizable value based on anticipated losses due to potentially uncollectible 
balances. Anticipated losses were based on management’s analysis of historical losses and changes in 
customer credit status. The fair value of capital lease obligations was approximately $22.9 million and $28.5 
million as of September 27, 2008 and September 29, 2007, respectively.  The fair value of the Company’s 
term loan debt was $120.4 million and $0 as of September 27, 2008 and September 29, 2007, 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 consisted of cash, cash equivalents, short-term investments and trade accounts 
receivable.  In accordance with the Company’s investment policy, the Company’s cash, cash equivalents and 
short-term investments were placed with recognized financial institutions.  The Company’s 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.  The Company, at times, requires 
advanced cash deposits for services performed.  The Company also closely monitors extensions of credit.  

New Accounting Pronouncements:   In September 2006, the FASB issued SFAS No. 157, “Fair 
Value Measurements” (“SFAS No. 157”).  This standard defines fair value, establishes a framework for 
measuring fair value in generally accepted accounting principles and establishes a hierarchy that categorizes 
and prioritizes the sources to be used to estimate fair value.  SFAS No. 157 also expands financial statement 
disclosures about fair value measurements.  On February 12, 2008, the FASB issued FASB Staff Position 
(“FSP”) 157-2 (“FSP 157-2”) which delays the effective date of SFAS No. 157 for one year, for all 
nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in 
the financial statements on a recurring basis (at least annually).  FAS No. 157 and FSP 157-2 are effective for 
financial statements issued for fiscal years beginning after November 15, 2007.  The Company is currently 
assessing the impact of SFAS No. 157 and FSP 157-2 on its consolidated results of operations, financial 
position and cash flows. 

In February 2007, the FASB issued Statement No. 159, “The Fair Value Option for Financial Assets 

and Financial Liabilities – Including an Amendment of FASB Statement No. 115” (“SFAS No. 159”).  This 
standard permits an entity to choose to measure many financial instruments and certain other items at fair 
value.  The fair value option permits a company to choose to measure eligible items at specified election 
dates.  A company will report unrealized gains and losses on items for which the fair value option has been 
elected in earnings after adoption.  The effective date for SFAS No. 159 is as of the beginning of fiscal years 
that start subsequent to November 15, 2007.  The Company is currently assessing the impact of SFAS No. 
159 on its consolidated results of operations, financial position and cash flows. 

In December 2007, the FASB issued SFAS No. 141R, “Business Combinations” (“SFAS No. 
141R”).  SFAS No. 141R states that all business combinations (whether full, partial or step acquisitions) will 
result in all assets and liabilities of an acquired business being recorded at their fair values.  Certain forms of 
contingent consideration and certain acquired contingencies will be recorded at fair value at the acquisition 
date.  SFAS No. 141R also states acquisition costs will generally be expensed as incurred and restructuring 
costs will be expensed in periods after the acquisition date.  This statement is effective for financial 
statements issued for fiscal years beginning after December 15, 2008.   

In December 2007, the FASB issued SFAS No. 160, “Non-controlling Interests in Consolidated 

Financial Statements — an amendment to ARB No. 51” (“SFAS 160”).  SFAS No. 160 will change the 
accounting and reporting for minority interests, which will now be termed “non-controlling interests.” 
SFAS No. 160 requires non-controlling interests to be presented as a separate component of equity and 
requires the amount of net income attributable to the parent and to the non-controlling interest to be 
separately identified on the consolidated statement of operations. SFAS No. 160 is effective for fiscal years 
beginning on or after December 15, 2008. The Company is currently assessing the impact of SFAS No. 160 
on its consolidated results of operations, financial position and cash flows. 

In March 2008, the FASB issued SFAS No. 161, “Disclosures about Derivative Instruments and 

Hedging Activities, an amendment of FASB Statement No. 133” (“SFAS No. 161”).  This statement changes 
the disclosure requirements for derivative instruments and hedging activities.  SFAS No. 161 requires 
enhanced disclosures about (a) how and why an entity uses derivative instruments, (b) how derivative 
instruments and related hedged items are accounted for under SFAS No. 133, “Accounting for Derivative 
Instruments and Hedging Activities” (“SFAS No. 133”) and its related interpretations, and (c) how derivative 
instruments and related hedged items affect an entity’s financial position, financial performance, and cash

beginning after November 15, 2008.  The Company is currently assessing the impact of SFAS No. 161 on its 
consolidated results of operations, financial position and cash flows.

On April 4, 2008, the Company entered into a second amended and restated credit agreement (the 

“Amended Credit Facility”) with a group of banks which allows the Company to borrow $150 million in term 
loans and $100 million in revolving loans.  The $150 million in term loans was immediately funded and the 
$100 million revolving credit facility is currently available.  The Amended Credit Facility is unsecured and 
the revolving credit facility may be increased by an additional $100 million (the “accordion feature”) if the 
Company has not previously terminated all or any portion of the Amended Credit Facility, there is no event 
of default existing under the Amended Credit Facility and both the Company and the administrative agent 
consent to the increase.  The Amended Credit Facility expires on April 4, 2013.  Borrowings under the 
Amended Credit Facility may be either through term loans or revolving or swing loans or letter of credit 
obligations.  As of September 27, 2008, the Company has term loan borrowings of $146.3 million 
outstanding and no revolving borrowings under the Amended Credit Facility. 

The Amended Credit Facility amended and restated the Company’s prior revolving credit facility 

(“Revolving Credit Facility”) with a group of banks that allowed the Company to borrow up to $200 million 
of which $100 million was committed.  The Revolving Credit Facility was due to expire on January 12, 2012 
and was also unsecured.  It also contained other terms and financial conditions, which were substantially 
similar to those under the Amended Credit Facility.   

 The Amended Credit Facility contains certain financial covenants, which include a maximum total 
leverage ratio, maximum value of fixed rentals and operating lease obligations, a minimum interest coverage 
ratio and a minimum net worth test, all as defined in the agreement.  As of September 27, 2008, the Company 
was in compliance with all debt covenants.  If the Company incurs an event of default, as defined in the 
Amended Credit Facility (including any failure to comply with a financial covenant), the group of banks has 
the right to terminate the remaining Revolving Credit Facility and all other obligations, and demand 
immediate repayment of all outstanding sums (principal and accrued interest).  Interest on borrowing varies 
depending upon the Company’s then-current total leverage ratio; as of September 27, 2008, the Company 
could elect to pay interest at a defined base rate or the LIBOR rate plus 1.25%.  Rates would increase upon 
negative changes in specified Company financial metrics and would decrease upon reduction in the current 
total leverage ratio to no less than LIBOR plus 1.00%.  The Company is also required to pay an annual 
commitment fee on the unused credit commitment based on its leverage ratio; the current fee is 0.30 percent.  
Unless the accordion feature is exercised, this fee applies only to the initial $100 million of availability 
(excluding the $150 million of term borrowings).  Origination fees and expenses associated with the Amended 
Credit Facility totaled approximately $1.3 million and have been deferred.  These origination fees and 
expenses will be amortized over the five-year term of the Amended Credit Facility.  Equal quarterly principal 
repayments of the term loan of $3.75 million per quarter began June 30, 2008 and end on April 4, 2013 with a 
balloon repayment of $75.0 million.  

The Amended Credit Facility allows for the future payment of cash dividends or the future repurchases 

of shares provided that no event of default (including any failure to comply with a financial covenant) is existing at 
the time of, or would be caused by, a dividend payment or a share repurchase.

Interest expense related to the commitment fee and amortization of deferred origination fees and 

expenses for the Amended Credit Facility totaled approximately $0.5 million, $0.6 million and $1.2 million 
for fiscal 2008, 2007 and 2006, respectively. 

Cash paid for interest in fiscal 2008, 2007 and 2006 was $4.2 million, $2.8 million and $2.9 million, 

respectively. 

5. 

Derivatives 

All derivatives are recognized in the Consolidated Balance Sheets at their estimated fair value.  On 

the date a derivative contract is entered into, the Company designates the derivative as a hedge of a recognized 
asset or liability (a “fair value” hedge), a hedge of a forecasted transaction or of the variability of cash flows to 
be received or paid related to a recognized asset or liability (a “cash flow” hedge), or a hedge of the net 
investment in a foreign operation. The Company does not enter into derivatives for speculative purposes. 
Changes in the fair value of a derivative that qualify as a fair value hedge are recorded in earnings along with 
the gain or loss on the hedged asset or liability. Changes in the fair value of a derivative that qualifies as a cash 
flow hedge are recorded in “Accumulated other comprehensive income” in the Consolidated Balance Sheets 
until earnings are affected by the variability of cash flows. Changes in the fair value of a derivative used to 
hedge the net investment in a foreign operation are recorded in the “Accumulated other comprehensive 
income” account within shareholders’ equity.  

In June 2008, the Company entered into three interest rate swap contracts related to the $150 million 
in term loans under the Amended Credit Facility that have a total notional value of $150 million and mature 
on April 4, 2013. These interest rate swap contracts will pay the Company variable interest at the three month 
LIBOR  rate,  and  the  Company  will  pay  the  counterparties  a  fixed  interest  rate.    The fixed  interest  rates  for 
each of these contracts are 4.415%, 4.490% and 4.435%, respectively.  These interest rate swap contracts were 
entered  into  to  convert  $150  million  of  the  variable  rate  term  loan  under  the  Amended  Credit  Facility  into 
fixed rate debt. Based on the terms of the interest rate swap contracts and the underlying debt, these interest 
rate contracts were determined to be effective, and thus qualify as a cash flow hedge. As such, any changes in 
the fair value of these interest rate swaps are recorded in “Accumulated other comprehensive income” on the 
Consolidated Balance Sheets until earnings are affected by the variability of cash flows. The total fair value of 
these interest rate swap contracts is $3.0 million at September 27, 2008, and the Company has recorded this in 
“Other” current liabilities and “Other liabilities” in the accompanying Consolidated Balance Sheets.

The Company recorded income tax expense of $18.5 million for both fiscal 2008 and fiscal 2007.  

The reduction to the income tax expense recorded as compared to our normal statutory rates is primarily due 
to the effect of pre-tax income in Malaysia and China, which benefit from reduced effective tax rates due to 
tax holidays.  

During fiscal 2006, the Company recorded minimal income tax expense as a result of the 
establishment in fiscal 2004 of a full valuation allowance on our U.S. deferred income tax assets as well as 
increased pre-tax income in Malaysia and China, which benefit from tax holidays, and reduced pre-tax 
income in the U.K..  In the fourth quarter of fiscal 2006, the Company reversed $17.7 million of the 
previously recorded valuation allowance as a credit to income taxes.

Under SFAS No. 109, “Accounting for Income Taxes,” historical and projected financial results 

(along with any other positive or negative evidence) should be considered when assessing our ability to 
generate future taxable income and realize any net deferred income tax assets.  The Company’s U.S. 
operations generated significant pre-tax income in fiscal 2006.  Based on our fiscal 2006 U.S. pre-tax income 
and an assessment of expected future profitability in the U.S., the Company concluded that it was more likely 
than not that the tax benefits of our cumulative net deferred income tax assets in the U.S. would be utilized in 
the future.  Therefore, the Company reversed $17.7 million of the valuation allowance as noted above.   

As a result of using the with-and-without method under SFAS No. 123(R), the Company recorded a 

valuation allowance against the amount of net operating loss and credit carryforwards related to tax 
deductions in excess of compensation expense for stock options until such time as the related deductions 
actually reduce income taxes payable.  The Company recorded a valuation allowance of $16.7 million in 
fiscal 2006 against its $42.5 million net operating loss carryforwards as of September 30, 2006.  During fiscal 
2007 and 2008, the Company realized a reduction of its income taxes payable for all of its federal net 
operating loss carryforwards and a portion of its state net operating loss carryforwards.  Consequently, the 
Company reversed approximately $15.0 million and $0.6 million of this valuation allowance with 
corresponding credits to additional paid in capital in fiscal 2007 and fiscal 2008, respectively.   

In addition, there is a remaining valuation allowance of $1.5 million as of September 27, 2008 

related to various state deferred income tax assets for which utilization is uncertain due to a lack of sustained 
profitability and limited carryforward periods in these states. 

In October 2007, the Mexican Congress enacted a series of new tax laws, effective beginning on 

January 1, 2008.  These laws did not have a material effect for our fiscal 2008 tax year.  However, these laws 
could have a significant effect on the taxes levied on our Mexican income in the future.   

In March 2007, the Chinese government made significant changes to its tax law with a bias toward a 
unified tax rate for domestic and foreign enterprises of 25 percent.  The law was effective on January 1, 2008.  
The effect of the law on enterprises with agreed-upon incentives requires that their China federal taxes will be 
increased to the new unified tax rate over a five-year period beginning in calendar 2008.  This law did not 
have a material effect on our income taxes for our fiscal 2008 tax year.  However, depending upon the 
relative amount of income earned in China in the future, the increased tax rates on our China income could 
create a material effect.

In July 2005, a legislative body in the United Kingdom enacted the Finance Act (the “Finance Act”), 

which limits 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. The Company currently extends loans 
from a U.S. subsidiary to a United Kingdom subsidiary, which is affected by the Finance Act.  For fiscal 
2008, 2007 and 2006, management provided income tax expense for the effect of the Finance Act on the non-
deductibility of this interest expense based on proposed agreement with the tax authorities in the United 
Kingdom regarding the application of the Finance Act to the Company’s circumstances. 

The Company has been granted tax holidays for its Malaysian and Chinese subsidiaries.  These tax 

holidays expire in 2019 and 2013, respectively, and are subject to certain conditions with which the Company 
expects to comply.  In fiscal 2008, 2007 and 2006, these subsidiaries generated income, which resulted in tax 
reductions of approximately $13.6 million, $8.6 million and $6.9 million, respectively.  

The Company does not provide for taxes that would be payable if undistributed earnings of foreign 

subsidiaries were remitted because the Company considers these earnings to be invested for an indefinite 
period.  The aggregate undistributed earnings of the Company’s foreign subsidiaries for which a deferred 
income tax liability has not been recorded is approximately $143.0 million as of September 27, 2008.  

In October 2004, the American Jobs Creation Act of 2004 (the “Jobs Act”) was signed into law in 

the United States.  The Jobs Act includes a deduction of 85 percent of certain foreign earnings that are 
repatriated, as defined in the Jobs Act.  During fiscal 2008, 2007 and 2006, the Company did not repatriate 
any qualified earnings pursuant to the Jobs Act.   

As of September 27, 2008, the Company has approximately $67.3 million of state net operating loss 

carryforwards that expire between fiscal 2009 and 2026.    

Cash paid for income taxes in fiscal 2008, 2007 and 2006 was $22.7 million, $2.2 million and $3.2 

million, respectively. 

In June 2006, the FASB issued interpretation No. 48, “Accounting for Uncertainty in Income Taxes -  
an interpretation of FASB Statement No. 109” (“FIN 48”).  FIN 48 addresses the determination of whether tax 
benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements by 
standardizing the level of confidence needed to recognize uncertain tax benefits and the process for measuring 
the amount of benefit to recognize.  FIN 48 also provides guidance on derecognition, classification, interest 
and penalties, accounting in interim periods, disclosure and transition.   

Effective at the beginning of fiscal 2008, the Company adopted FIN 48.  Upon adoption, the 

Company recorded an increase in income tax liabilities for uncertain tax benefits and a decrease in valuation 
allowance of approximately $0.8 million, which resulted in no cumulative effect adjustment to retained 
earnings.  During the three months ended June 28, 2008, approximately $1.0 million of valuation allowance 
was recorded to retained earnings as an out-of-period adjustment as a result of the additional review of the 
interaction between the assessment of valuation allowances and FIN 48.  The Company does not believe the 
adjustment was material to its Consolidated Financial Statements for fiscal 2008, or any previously issued 
financial statements.   

As required by FIN 48, the Company has classified the amounts recorded for uncertain tax positions 

in the Consolidated Balance Sheets as “Other liabilities” (non-current) to the extent that payment is not 
anticipated within one year.  Prior year financial statements have not been restated.  Presented below is a 
reconciliation of the beginning and ending amounts of unrecognized income tax benefits:

Approximately $5.1 million and $3.8 million of the balances as of September 27, 2008, and at the 

beginning of fiscal 2008, respectively, would reduce the Company’s effective tax rate if recognized.   

The Company recognizes accrued interest and penalties related to unrecognized tax benefits in 

income tax expense.  The total accrued penalties and net accrued interest with respect to income taxes was 
approximately $0.4 million and $0.1 million as of September 27, 2008, and upon the Company’s adoption of 
FIN 48 at the beginning of fiscal 2008, respectively.  The Company recognized $0.4 million of expense for 
accrued penalties and net accrued interest in the Consolidated Statements of Operations for the year ended 
September 27, 2008. 

It is reasonably possible that a number of uncertain tax positions related to federal and state tax 
positions may be settled within the next 12 months.  Settlement of these matters is not expected to have a 
material effect on the Company’s consolidated results of operations, financial position and cash flows.     

Upon adoption, the Company had tax years from fiscal 2004 and forward open and subject to 

examination by the Internal Revenue Service (“IRS”).  For the major state tax jurisdictions, the Company has 
fiscal 2001 and forward open and subject to examination. 

7. 

Shareholders’ Equity  

On February 25, 2008, the Company announced approval by its board of directors of a new share 

repurchase program authorizing the Company to repurchase up to $200 million of common stock.  The new 
repurchase authorization replaced the Company’s existing authorization to repurchase up to $25 million in 
common stock. 

Also on February 25, 2008, the Company entered into two accelerated stock repurchase (“ASR”) 

agreements with Morgan Stanley & Co. Incorporated (“Morgan Stanley”) to repurchase an aggregate of $100 
million of its common stock.  On February 26, 2008, the Company paid $100 million to Morgan Stanley in 
exchange for a variable number of shares over a variable period of time.  The final total number of shares to 
be repurchased under the ASR agreements was based generally on the volume-weighted average price of the 
Company’s common stock during the term of the agreements.  Purchases under one of the ASR agreements 
were subject to collar provisions that established minimum and maximum numbers of shares based on the 
average price at which Morgan Stanley purchases shares over an initial hedge period to establish its hedge 
position.  Under the collared ASR agreement, the Company’s common stock repurchases totaled $50 million.  
The remaining $50 million of share repurchases under the ASR program were not subject to collar provisions.  
On April 24, 2008, the Company completed its ASR program with a total of 3.8 million shares purchased at a 
volume-weighted average price of $26.51 per share.  

In addition to the ASR agreements, the Company announced that the remaining $100 million of 

authorized share repurchases would be repurchased in the open market.  The Company repurchased 3.6 
million shares at a volume-weighted average price of $27.25 per share in the open market.  Therefore, the 
Company completed the $200 million share repurchase program with a total purchase of 7.4 million shares at 
a volume-weighted average price of $26.87 per share.  The Company’s Amended Credit Facility allows the 
Company to repurchase its common shares and pay cash dividends as long as it remains in compliance with 
the various covenants (see Note 4). 

As of August 28, 2008, the Company declared a dividend of one preferred share purchase right (a 

“Right”) for each outstanding share of common stock, par value $0.01 per share, of the Company.  The 
dividend was payable on September 26, 2008 to the shareholders of record upon the close of business on 
September 12, 2008.  Each Right entitled the registered holder to purchase from the Company one one-
hundredth of a share of Series B Junior Participating Preferred Stock, $0.01 par value per share (“Preferred 
Share”), of the Company, at a price of $125.00 per one one-hundredth of a Preferred Share, subject to 
adjustment.  The Rights will expire on August 28, 2018, subject to extension.  This was the renewal of a 
similar plan that expired on August 12, 2008.

In fiscal 2008, stock options and stock-settled stock appreciation rights (‘SARs”) to purchase 
approximately 1.5 million shares were outstanding but were not included in the computation of diluted 
earnings per share because the options’ and SARs’ exercise prices were greater than the average market price 
of the common shares and, therefore, their effect would be antidilutive.  In fiscal 2007 and 2006, options to 
purchase 1.9 million and 0.9 million shares, respectively, of common stock were outstanding but not included 
in the computation of diluted earnings per share because the options’ exercise prices were greater than the 
average market price of the common shares and, therefore, their effect would be antidilutive.

Operating 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 2008, 2007 and 
2006 was approximately $11.5 million, $10.6 million and $10.4 million, respectively.  Renewal and purchase 
options are available on certain of these leases.  Rental income from subleases amounted to $0, $0, and $0.2 
million in fiscal 2008, 2007 and 2006, respectively.

Restructuring and Impairment Costs 

Fiscal 2008 restructuring and impairment costs:  For fiscal 2008, we recorded pre-tax restructuring 
and asset impairment costs of $2.1 million, related to the closure of our Ayer, Massachusetts (“Ayer”) facility 
and the restructuring of our workforce in Juarez, Mexico (“Juarez”).  The details of these fiscal 2008 
restructuring actions are listed below: 

Ayer Facility Closure:  During the fourth quarter of fiscal 2008, we announced our intention to close 

our Ayer facility.  In fiscal 2008, we recorded pre-tax restructuring charges of $1.9 million, related to 
severance for 170 impacted employees and costs to retain certain employees.  In addition to the costs in fiscal 
2008, approximately $0.4 million of costs related to the disposal of certain assets and costs to exit the leased 
facility are expected to be incurred through the second fiscal quarter of 2009.  The closure of the facility is 
expected by March 2009. 

Other Restructuring Costs.  In fiscal 2008, we recorded pre-tax restructuring costs of $0.2 million 

related to severance at our Juarez facility.  The Juarez workforce reductions affected approximately 20 
employees. 

Fiscal 2007 restructuring and asset impairment costs: For fiscal 2007, we recorded pre-tax 

restructuring and asset impairment costs of $1.8 million, related to the closure of our Maldon, England 
(“Maldon”) facility and the reduction of our workforces in Juarez and Kelso, Scotland (“Kelso”).  The details 
of these fiscal 2007 restructuring actions are listed below:  

Maldon Facility Closure:  The Maldon facility ceased production on December 12, 2006, and its 

closure resulted in a workforce reduction of 75 employees at a cost of $0.5 million.  During the second fiscal 
quarter, the Company sold the Maldon facility for $4.4 million and recorded a $0.4 million gain on this 
transaction.    

Other Restructuring Costs.  In fiscal 2007, we recorded pre-tax restructuring costs of $1.0 million 

related to severance at our Juarez facility. The Juarez workforce reductions affected approximately 125 
employees.  During fiscal 2007, we also recorded pre-tax restructuring costs of $0.3 million related to 
severance at our Kelso facility.  The Kelso workforce reductions affected approximately 10 employees.

Fiscal 2006 restructuring and asset impairment costs: For fiscal 2006, the Company recorded pre-

tax restructuring and asset impairment costs of $1.0 million, related to the decision to close its Maldon 
facility and to reduce the workforce in Juarez.  For fiscal 2006, these restructuring costs were offset by 
reductions in lease obligations of $0.8 million, as a result of the Company entering into lease termination or 
sublease agreements for three of its previously closed facilities in the Bothell and Seattle, Washington area, as 
well as favorable adjustments totaling $0.2 million for fiscal 2006, related to other restructuring accruals. The 
details of the fiscal 2006 restructuring actions are listed below:  

Maldon Facility Closure:   The Company announced in July 2006 its intention to close the Maldon 

facility.  In fiscal 2006 the Company recorded $0.5 million for severance and asset impairments related to the 
expected closure of the Maldon facility.  This restructuring affected 75 employees.     

Maldon Facility Conversion:   In the third quarter of fiscal 2005, the Company announced a planned 
workforce reduction at the Maldon facility as the Company decided to convert this manufacturing facility to a 
fulfillment, service and repair facility.  As a result of this planned conversion, the Company recorded 
expenses of $0.2 million for retention costs in fiscal 2006 related to the workforce reduction as part of the 
Maldon facility conversion. This restructuring affected 43 employees.   

Other Restructuring Costs.  For fiscal 2006, the Company recorded pre-tax restructuring costs of 

$0.3 million related to severance at its Juarez facility. The Juarez workforce reductions affected 
approximately 46 employees.

Benefit Plans 

Employee Stock Purchase Plans: Under the shareholder-approved 2005 Employee Stock Purchase 

Plan (the “2005 Purchase Plan”), the Company could issue up to 1.2 million shares of its common stock. The 
terms of the 2005 Purchase Plan originally allowed for qualified employees to participate in the purchase of 
the Company’s common stock at a price equal to the lower of 85 percent of the average high and low stock 
price at the beginning or end of each semi-annual stock purchase period. The 2005 Purchase Plan was 
effective on July 1, 2005.   

As subsequently amended, the 2005 Purchase Plan allowed qualified employees to purchase the 

Company’s common stock at a price equal to 95 percent of the average high and low stock price at the end of 
each semi-annual purchase period.  The effect of the amendment was to reduce the discount available to 
employees who purchase shares under the 2005 Purchase Plan.  With the amendment, the Company did not 
record any compensation expense related to the 2005 Purchase Plan under SFAS No. 123(R) in fiscal 2008 
and 2007.  

The Company issued 6,976 shares and 17,751 shares under the 2005 Purchase Plan during the fiscal 
years ended September 27, 2008 and September 29, 2007, respectively.  Purchases under the 2005 Purchase 
Plan were terminated by the board of directors in January 2008.  Therefore, no additional shares will be 
offered or issued under the 2005 Purchase Plan, which will expire in 2010.     

401(k) Savings Plan:  The Company’s 401(k) Savings Plan covers all eligible U.S. employees.  The 

Company matches employee contributions, after one year of service, up to 2.5 percent of eligible earnings.  
The Company’s contributions for fiscal 2008, 2007 and 2006 totaled $2.8 million, $2.4 million and $2.2 
million, respectively.

Stock-based  Compensation  Plans:  In  February  2008,  the  Company’s  shareholders  approved  the 
Plexus Corp. 2008 Long-Term Incentive Plan (the “2008 Plan”), a stock-based incentive plan for officers, key 
employees  and  directors;  the  2008  Plan  includes  provisions  by  which  the  Company  may  grant  stock-based 
awards, including stock options, stock-settled stock appreciation rights (“SARs”), restricted stock, restricted 
stock  units  (“RSUs”)  and  performance  stock,  in  addition  to  long-term  cash  awards,  to  directors,  executive 
officers  and  other  officers  and  key  employees.    The  maximum  number  of  shares  of  Plexus  common  stock 
which may be issued pursuant to the 2008 Plan is 5,500,000 shares; in addition, long-term cash awards of up 
to $1.5 million may be granted annually.  The exercise price of each stock option and SAR granted must not 
be  less  than  the  fair  market  value  on  the  date  of  grant.    The  Compensation  and  Leadership  Development 
Committee  (the  “Committee”)  of  the  board  of  directors  may  establish  a  term  and  vesting  period  for  stock 
options,  SARs  and  other  awards  under  the  2008  Plan  as  well  as  accelerate  the  vesting  of  such  awards.  
Currently,  stock  options  vest  in  two  annual  installments  and  have  a  term  of  ten  years,  SARs  vest  in  two 
annual installments and have a term of seven years, and RSUs fully vest on the third anniversary of the grant 
date  (assuming  continued  employment),  which  is  also  the  date  as  of  which  the  underlying  shares  will  be 
issued.

The 2008 Plan replaces the shareholder-approved 2005 Equity Incentive Plan (the “2005 Plan”). 
The 2005 Plan constituted a stock-based incentive plan for the Company and included provisions by which 
the Company could grant stock-based awards to directors, executive officers and other officers and key 
employees. The maximum number of shares of Plexus common stock that could be issued pursuant to the 
2005 Plan was 2.7 million shares, all of which could be issued pursuant to stock options, although up to 1.2 
million shares could be issued pursuant to the following: up to 0.6 million shares as SARs and up to 0.6 
million shares as RSUs. The exercise price of each stock option granted must have been not less than the fair 
market value on the date of grant.  The Committee could establish the term and vesting period of stock 
options, as well as accelerate the vesting of stock options. Unless otherwise directed by the Committee, stock 
options vested over a three-year period from date of grant and had a term of ten years.  In fiscal 2007, the 
Committee established that the vesting period for stock options would be two years.  The 2005 Plan 
terminated upon the approval of the 2008 Plan, except that outstanding awards continue until expiration.   

During fiscal 2007, the Committee changed the timing of stock option grants so that they would be 

determined annually, but granted on a quarterly basis going forward.  In fiscal 2008, the Committee 
continued that practice under the 2008 Plan and extended it to grants of SARs.  However, grants of RSUs and 
long-term cash awards are made only on an annual basis. 

For options issued to the members of the board of directors in fiscal 2008, fiscal 2007 and fiscal 

2006, 50 percent of their stock options vested immediately at the date of grant.  Their remaining stock options 
vested over one year.   

The Company granted options, SARs and RSUs to purchase 2.1 million shares of the Company’s 

common stock under the 2005 Plan from the approval date of the 2005 Plan through September 27, 2008.  In 
fiscal 2008, the Company granted options to purchase 0.1 million shares of the Company’s stock, which had a 
term of ten years and 0.2 million stock-settled SARs, which had a term of seven years.  Additionally, the 
Committee made awards of RSUs for 0.1 million shares of common stock and long-term cash awards that 
totaled $0.7 million, all of which vest on the third anniversary of grant.  Under the 2008 Plan, the Company 
granted options to purchase 0.1 million shares of the Company’s common stock and 0.2 million stock-settled 
SARs from the approval date of the 2008 Plan through September 27, 2008. 

The Company recognized $8.7 million of compensation expense associated with stock options and 

SARs for the fiscal year ended September 27, 2008, and $6.2 million and $3.0 million of compensation 
expense associated with stock options for the fiscal years ended September 29, 2007 and September 30, 2006, 
respectively.  No SARs were granted in fiscal 2007 or 2006.

The Company continues to use the Black-Scholes valuation model to value options and SARs. The 

Company used its historical stock prices as the basis for its volatility assumptions. The assumed risk-free 
rates were based on U.S. Treasury rates in effect at the time of grant with a term consistent with the expected

The weighted average fair value per share of options and SARs issued for the fiscal years ended 

September 27, 2008, September 29, 2007, and September 30, 2006 were $11.30, $11.05 and $20.04,

For the fiscal years ended September 27, 2008 and September 29, 2007, the total intrinsic value of 

options exercised was $4.9 million and $1.9 million, respectively. 

As of September 27, 2008, there was $8.9 million of unrecognized compensation cost related to non-

The Company uses the fair value at the date of grant to value RSUs.  As of September 27, 2008, 

there was $2.2 million of total unrecognized compensation cost related to restricted stock unit awards granted 
under the 2005 Plan. 

Deferred Compensation Arrangements:  In September 1996, the Company entered into agreements 

with certain of its former executive officers to provide nonqualified deferred compensation.  Under those 
agreements, the Company agreed to pay to these former executives, or their designated beneficiaries upon 
such executives’ deaths, certain amounts annually for the first 15 years subsequent to their retirements.  Life 
insurance contracts owned by the Company fund this plan.   

In fiscal 2000, the Company established a supplemental executive retirement plan (the “SERP”) as 

an additional deferred compensation plan for executive officers and other key employees.  Under the SERP, a 
covered executive may elect to defer some or all of the participant’s compensation into the plan, and the

Company may credit the participant’s account with a discretionary employer contribution.  Participants are 
entitled to payment of deferred amounts and any related earnings upon termination or retirement from Plexus.  

In fiscal 2003, due to changes in the law, Plexus terminated a split-dollar life insurance program 

under the SERP and replaced it with a rabbi trust arrangement (the “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 in the Trust.  In fiscal 
2008, 2007 and 2006, the Company made contributions to the participants’ SERP accounts in the amount of 
$0.5 million, $0.4 million and $0.3 million, respectively.  The increase in the Company’s contributions in 
fiscal 2006 was the result of the Company’s board of directors’ determination to increase the Company’s 
discretionary contributions to the greater of 7 percent of the executive’s total target cash compensation less 
the Company’s permitted contributions to the executive’s 401(k) Savings Plan account or $13,500.  The 
contributions were made in fiscal 2006 as though this policy had been in effect for fiscal 2005 as well.   

As of September 27, 2008 and September 29, 2007, the SERP assets held in the Trust totaled $5.1 
million and $5.1 million, respectively and the related liability to the participants totaled approximately $3.7 
million and $4.8 million, respectively.  The Trust assets are subject to the claims of the Company’s creditors.  
The Trust assets and the related liabilities 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.

Litigation 

Two securities class action lawsuits were filed in the United States District Court for the Eastern 
District of Wisconsin on June 25 and June 29, 2007, against the Company and certain Company officers 
and/or directors.  On November 7, 2007, the two actions were consolidated, and a consolidated class action 
complaint was filed on February 1, 2008.  The consolidated complaint names the Company and the 
following individuals as defendants:  Dean A. Foate, President, Chief Executive Officer and a Director of the 
Company; F. Gordon Bitter, the Company's former Senior Vice President and Chief Financial Officer; 
and Paul Ehlers, the Company’s former Executive Vice President and Chief Operating Officer.  The 
consolidated complaint alleges securities law violations and seeks unspecified damages relating generally to 
the Company’s statements regarding its defense sector business in early calendar 2006.  On April 15, 2008, 
the Company and the individual defendants filed a motion to dismiss the consolidated class action complaint.  
The plaintiff is opposing the dismissal.  The briefing on the defendants’ motion has been completed; 
however, the Court has not yet held a hearing or ruled on the motion.

The Company believes the allegations in the consolidated complaint are wholly without merit and it 
intends to vigorously defend against them.  Since these matters are in the preliminary stages, the Company is 
unable to predict the scope or outcome or quantify their eventual impact, if any, on the Company.  At this 
time, the Company is also unable to estimate associated expenses or possible losses.  The Company maintains 
insurance that may reduce its financial exposure for defense costs and liability for an unfavorable outcome, 
should it not prevail. 

The Company is party to 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’s consolidated results of operations, financial position or cash flows.  Due to their immateriality, all 
expenses associated with these lawsuits are expensed as incurred.

Reportable Segment, Geographic Information and Major Customers 

SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information” (“SFAS No. 

131”) establishes standards for reporting information about segments in financial statements.  Reportable 
segments are defined as components of an enterprise about which separate financial information is available 

66

 
Plexus Corp.

that is evaluated regularly by the chief operating decision maker, or group, in assessing performance and 
allocating resources.   

The Company uses an internal management reporting system, which provides important financial 

data to evaluate performance and allocate the Company's resources on a geographic basis.  Net sales 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 and administrative expenses, but excludes corporate and other costs, interest expense, 
interest income, other income (expense) and income tax expense (benefit). Corporate and other costs 
primarily represent corporate selling 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's length transactions. The accounting policies for the regions are the same as for the Company taken as a 
whole.  

Information about the Company’s four reportable segments in fiscal 2008, 2007 and 2006 were as

Guarantees  

The Company offers certain indemnifications under its customer manufacturing agreements. In the 

normal course of business, the Company may from time to time be obligated to indemnify its customers or its 
customers’ customers against damages or liabilities arising out of the Company’s negligence, misconduct, 
breach of contract, or infringement of third party intellectual property rights.  Certain of the agreements have 
extended broader indemnification rights, and while most agreements have contractual limits, some do not.  
However, the Company generally does not provide for such indemnities, and seeks indemnification from its 
customers, for damages or liabilities arising out of the Company’s adherence to customers’ specifications or 
designs, or use of materials furnished, or directed to be used, by its customers.  The Company does not 
believe its obligations under such indemnities are material. 

In the normal course of business, the Company also provides its customers a limited warranty 
covering workmanship, and in some cases materials, on products manufactured by the Company.  Such 
warranty generally provides that products will be free from defects in the Company’s workmanship and meet 
mutually agreed upon specifications for periods generally ranging from 12 months to 24 months.  If a product 
fails to comply with the Company’s limited warranty, the Company’s obligation is generally limited to 
correcting, at its expense, any defect by repairing or replacing such defective product.  The Company’s 
warranty generally excludes defects resulting from faulty customer-supplied components, design defects or 
damage caused by any party or cause other than the Company.  

The Company provides for an estimate of costs that may be incurred under its limited warranty at the 

time product revenue is recognized and establishes additional reserves for specifically identified product 
issues.  These costs primarily include labor and materials, as necessary, associated with repair or replacement 
and are included in our Consolidated Balance Sheets in other current accrued liabilities.  The primary factors 
that affect the Company’s warranty liability include the value and the number of shipped units and historical 
and anticipated rates of warranty claims.  As these factors are impacted by actual experience and future

expectations, the Company assesses the adequacy of its recorded warranty liabilities and adjusts the amounts 
as necessary.
