Plexus is passionate about its goal to be the leading Electronic Manufacturing Services company in the
world at servicing mid-to-low volume, higher complexity customer programs characterized by unique
flexibility, technology, quality and regulatory requirements. We have aligned our business operations,
processes, workforce and financial metrics to support this strategy.

We operate flexible manufacturing facilities and processes designed to accommodate customers with
multiple product-lines and configurations. 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 in these sectors. These teams also help set our strategy for growth in these 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”) 500 basis points 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 value for our
shareholders.

Established in 1979, Plexus has approximately 9,000 employees located in 24 active facilities around the
world. These facilities are strategically located to support the global supply chain, manufacturing and
engineering needs of original equipment manufacturers in our targeted market sectors. Plexus’ global
manufacturing and engineering footprint is outlined below:

ANNUAL MEETING OF SHAREHOLDERS 
FEBRUARY 15, 2012 

COMMONLY ASKED QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING 

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

A:  On or about December 16, 2011, Plexus Corp. (“Plexus”, “we” or the “Company”) expects to mail shareholders 
a Notice of Internet Availability of Proxy Materials containing instructions on how to access the proxy material over 
the internet. 

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

A:  Pursuant to the rules 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, we are mailing 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.    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 Materials or provided below.  

Important Notice Regarding the Availability of Proxy Materials for 
 the Shareholder Meeting to Be Held on February 15, 2012 

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?

1

Q: WHAT AM I VOTING ON? 

A:  At the annual meeting you will be voting on three 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: 

•  Ralf R. Böer 
•  Stephen P. Cortinovis 
•  David J. Drury 
•  Dean A. Foate 
•  Peter Kelly 

•  Phil R. Martens 
•  John L. Nussbaum  
•  Michael V. Schrock 
•  Mary A. Winston 

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

independent auditor for 2012. 

3.  An  advisory  proposal  to  approve  the  compensation  of  the  Company’s  named  executive  officers,  as 

disclosed in “Compensation Discussion and Analysis” and “Executive Compensation” herein. 

Q: WHAT ARE THE BOARD’S VOTING RECOMMENDATIONS? 

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

•  FOR each of the nominees for election to the board of directors; 

•  FOR  the  ratification  of  the  Audit  Committee’s  selection  of  PricewaterhouseCoopers  LLP  as  Plexus’ 

independent auditors for 2012; and 

• FOR approval of the compensation of the Company’s named executive officers. 

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 that 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  that  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.    The  plurality  of  votes  cast  will  also  be  used  to 
determine the results of the advisory vote to approve the compensation of the Company’s named executive officers.  
Abstentions and broker non-votes will not affect these votes, except insofar as they reduce the number of shares that 
are voted. 

2

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 
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  no  longer  vote  your  shares  in  its 
discretion in the election of directors; therefore, you must vote your shares if you want them to be counted in the 
election of directors.  In addition, your broker is also not permitted to vote your shares in its discretion regarding 
matters  related  to  executive  compensation,  including  advisory  votes  on  executive  compensation.    However,  your 
broker may vote your shares in its discretion on routine matters such as the 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 8, 2011, which is the “Record Date.”  As of the Record Date, Plexus had 34,625,591 
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. 

•   By internet:  Go to www.proxyvote.com.  Please have the notice we sent to you in hand because it has 

your personal 12 digit control number(s) needed for your vote. 

•   By telephone:  On a touch-tone telephone, call 1-800-690-6903.  Please have the notice we sent to you in 

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

•   By mail: 

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. 

3

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 8, 2011, 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: 

•  Bring proof of ownership of Plexus common stock and a form of identification; or 
•  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? 

If you complete a proxy card or vote via the internet, you may still vote in person at the annual meeting. To 
A: 
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. 

4

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 a 
Notice of Internet Availability of Proxy Materials to all shareholders; paper copies of the proxy material will be sent 
upon request as provided above as well as in the 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. 

Q: WHEN  ARE  SHAREHOLDER  PROPOSALS  AND  SHAREHOLDER  NOMINATIONS  DUE  FOR  THE 
2013 ANNUAL MEETING? 

A:  The Secretary must receive a shareholder proposal no later than August 18, 2012, in order for the proposal to be 
considered  for  inclusion  in  our  proxy  materials  for  the  2013  annual  meeting.  The  2013  annual  meeting  of 
shareholders is tentatively scheduled for February 13, 2013.  To otherwise bring a proposal or nomination before the 
2013  annual  meeting,  you  must  comply  with  our  bylaws.    Currently,  our  bylaws  require  written  notice  to  the 
Secretary between October 7, 2012, and November 1, 2012.  The purpose of this 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 1, 2012, 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

ELECTION OF DIRECTORS  

Plexus believes that it needs to attract and retain talented, focused, and motivated leadership to develop the 
long-term  strategy  and  deliver  the  economic  profit  that  our  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 ten 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.

The  following  is  the  Company’s  current  matrix  of  experience  for  our  board,  which  together  with  the 
directors’ principal occupations and business experience described above, as well as the Company’s board member 
selection criteria, provide the reasons that each individual is being re-nominated as a director.  Boxes marked with 
an “X” in the matrix below indicate that the particular experience is one of the specific reasons that the director has 
been re-nominated to serve on the board.  The lack of an “X” does not mean that the director does not possess that 
experience,  but  rather  that  it  is  not  a  particular  area  of  focus  or  expertise  of  the  director  which  was  specifically 
identified as a reason for that director’s nomination.

Board of Directors Meetings 

CORPORATE GOVERNANCE 

The board of directors held four meetings during fiscal 2011.  As part of these meetings, non-management 
directors  regularly  meet  without  management  present.    All  of  our  directors  attended  at  least  75%  of  the  total 
meetings  of  the  board  and  the  committees  of  the  board  on  which  they  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  directors  attended  the  2011  annual  meeting  of 
shareholders.

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 Stock 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. 

• Mr.  Kelly  is  an  executive  officer  of  NXP  Semiconductors  N.V.,  which  is  a  supplier  to  Plexus.  
Plexus’  payments  to  NXP’s  distributors  in  fiscal  2011  were  $3,146,621,  which  represented 
approximately one-tenth of one percent of each of Plexus’ and NXPs annual revenues. 

• Mr.  Schrock  is  an  executive  officer  of  Pentair,  Inc.,  which  is  a  supplier  to  Plexus.    Plexus’ 
payments to Pentair in fiscal 2011 were $1,693,419, which represented less than one-tenth of one 
percent of each of Plexus’ and Pentair’s annual revenues. 

Based  on  the  applicable  standards  and  the  board’s  review  and  consideration,  the  board  of  directors  has 
determined  that  Messrs.  Böer,  Cortinovis,  Drury,  Kelly,  Martens  and  Schrock,  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. 

12 

 
Board Leadership Structure  

Mr. Nussbaum, our former Chief Executive Officer, serves as the Chairman of the Board.  The Company 
believes  that  having  our former  CEO  serve  as  Chairman  is  an  appropriate  leadership  structure  at  the  current  time 
because  Mr.  Nussbaum  has  extensive  knowledge  of  the  Company  and  the  EMS  industry,  which  continue  to  be 
valuable in communicating with and leading the board in his role as Chairman. 

The Company’s bylaws do not mandate, nor does the board have a policy that requires, the separation or 
combination  of  the  CEO  and  Chairman  roles.    The  board  may  reconsider  our  leadership  structure  in  the  future, 
including in connection with its succession planning efforts, based on the best interests of the Company at that time. 

Board’s Role in Risk Oversight 

It  is  management’s  responsibility  to  manage  the  Company’s  enterprise  risks  on  a  day-to-day  basis.  
Through  regular  updates,  the  board  of  directors  oversees  management’s  efforts  to  ensure  that  they  effectively 
identify, prioritize, manage and monitor all material business risks to Plexus’ strategy.   

The  board  delegates  certain  risk  management  oversight  responsibilities  to  its  committees.    The  Audit 
Committee  reviews  and  discusses  the  Company’s  major  financial  risk  exposures  and  the  steps  management  has 
taken  to  identify,  monitor  and  control  such  risks.    The  Compensation  and  Leadership  Development  Committee  is 
responsible  for  overseeing  risk  related  to  the  Company’s  compensation  programs,  including  considering  whether 
such  programs  are  in  line  with  the  Company’s  strategic  objectives  and  incentivize  appropriate  risk-taking.    The 
Nominating  and  Corporate  Governance  Committee  is  tasked with  risks  associated  with  corporate  governance  and 
compliance. 

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  2011.    The  Audit  Committee  chooses  the  Company’s 
independent auditors and oversees the audit process as well as the Company’s accounting, finance and tax functions.  
Among its other responsibilities, the Committee also oversees the Company’s ethics and whistle-blowing reporting 
programs,  in  conjunction  with  the  Nominating  and  Corporate  Governance  Committee.    See  also  “Report  of  the 
Audit Committee.”

 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 six 
meetings  during  fiscal  2011.    The  Committee  establishes  the  general  compensation  philosophies  and  plans  for 
Plexus,  determines  the  CEO’s  and  other  executive  officers’  compensation  and  approves  equity  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  Discussion  and  Analysis”  and 
“Compensation  Committee  Report” below  for further  information  on  the  Committee’s philosophies and  practices, 
and its determinations in fiscal 2011. 

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. 

When  determining  compensation  in  fiscal  2011,  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  performed  a 
full  review  of  the  composition  of  the  peer  group  during  fiscal  2010  because,  due  to  acquisitions  within  the  peer 
group and other changes, the Committee believed that certain companies had become less comparable to Plexus than 
when  they  were  originally  selected.    The  Committee  intends  to  conduct  reviews  of  the  peer  group  and  selection 
criteria  on  a  periodic  basis  to  ensure  that  both  are  appropriate.    Consistent  with  the  selection  of  its  previous  peer 
group,  companies  were  chosen  using  filtering  criteria,  such  as  industry  codes,  peer  companies  identified  as 
competitors,  company  size  and  employee  base,  profitability, geographic  location,  company  complexity  and  recent 
financial  performance;  anomalies  or  special  circumstances  (primarily  acquisitions  or  significant  size  differences) 
that  caused  certain  companies  to  not  be  in  fact  comparable  were  also  reviewed.    In  addition,  the  Committee  also 
identified  financial  peers  that  were  not  in  a  similar  business  but  which  were  similar  in  size  and  financial 
performance to Plexus. 

Our resulting peer group for fiscal 2011 compensation planning consisted of: 

• Agilent Technologies, Inc. 
• Altera Corporation 
• Amphenol Corporation 
• Arris Group, Inc. 
• AVX Corporation 
•

Benchmark Electronics, Inc. 

Bruker Corporation 
Celestica Inc. 
Esterline Technologies Corporation 

•
•
•
• Harris Corporation 
•
•

Invacare Corporation 
Jabil Circuit, Inc. 

• Molex Incorporated 
•
Regal-Beloit Corporation 
•
Sanmina-SCI Corporation 
•
Teledyne Technologies Incorporated 
•
Trimble Navigation Limited 
• Vishay Intertechnology, Inc. 

This peer group is being used for fiscal 2012 executive compensation planning.

When making compensation determinations, the Committee’s analysis includes a review of the Company’s 
financial  results,  an  internal  calibration  of  pay  and  equity  award  levels  and  an  accumulated  value  analysis.    In 
performing  these  analyses,  the  Committee  continues  to  use  tally  sheets,  which  provide  a  comprehensive  view  of 
Plexus’  compensation  payout  exposure  under  various  performance  scenarios,  and  also  assist  in  the  Committee’s 
evaluation of the reasonableness of compensation as a whole.  The accumulated value analysis examines the CEO’s 
accumulation of wealth through the deferred compensation plan and annual equity awards.  These assessments also 
identify the proportionality of the CEO’s pay to the pay of executives at other levels in the organization and compare 
this  information  with  published  survey  data.    In  addition,  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. 

In  addition  to  reviewing  compensation  to  help  assure  that  it  provides  an  incentive  for  strong  Company 
performance,  the  Company  and  the  Committee  periodically  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 use its judgment in applying this information 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  Company  performance.    The Committee  believes  this  approach 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. 

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 any recommendation for the CEO’s compensation, nor does management make the final 
determination of the CEO’s or the other executive officers’ amount or form of executive 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 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,  as  well  as 
accumulated value, 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.

For fiscal 2011 compensation planning, at the direction of the Committee, Towers Watson was engaged to 
conduct  a  detailed  analysis  of  the  Company’s  current  executive  compensation  package,  as  described  above.    For 
fiscal 2012 compensation planning, the Committee directed the Company’s internal human resources staff to prepare 
an  analysis  of  the  Company’s  executive  compensation  package  consistent  with  prior  years.  Plexus’  internal  staff 
obtained  market-based  data  to  provide  the Committee  with  the  same  data  and  analysis  as  in  previous  years.    It  is 
expected that an external firm will perform a detailed analysis of the Company’s executive compensation package 
every other year going forward; therefore, we anticipate that Towers Watson will be preparing such an analysis for 
fiscal 2013 compensation planning.

Neither  the  Company  nor  the  Committee  places  any  limitations  or  restrictions  on  its  consulting  firms  or 
their reviews.  Towers Watson and previous consulting firms have been retained by the Company only for projects 
related to the Company’s executive and director 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  Committee  was  an  independent  director  and  there  were  no  relationships  or 
transactions  in  fiscal  2011  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  two times in 
fiscal 2011.  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 
and ethics efforts, and evaluates as well as 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.  As described above in “Election of Directors,” in accordance with the Company’s 
board  member  selection  criteria,  the  Nominating  Committee  considers  the  diversity  of  backgrounds,  skills  and 
experiences 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 composition of the Board is reviewed annually to insure that an appropriate mix 
of  skills,  experiences  and  backgrounds  is  represented;  the  membership  mix  of  the  Board  may  also  be  changed  as 
necessary to meet business needs.    

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 would review the background of the candidate and, if appropriate, meet with the candidate.  A decision 
would then be made whether to nominate that person to the board.  The Nominating Committee’s policy is to not 
evaluate proposed nominees differently depending upon who has proposed the potential nominee. 

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  “Commonly  Asked  Questions  and  Answers 
About the Annual Meeting” for bylaw requirements for nominations.  Plexus has neither received nor rejected any 
candidates put forward by significant shareholders. 

16 

 
Communications with the Board 

Any  communications  to  the  board  of  directors  should  be  sent  to  Plexus’  headquarters  office  in  care  of 
Plexus’  Secretary,  Angelo  M.  Ninivaggi.    Any  communication  sent  to  the  board  in  care  of  the  Chief  Executive 
Officer, the 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), director and officer stock ownership guidelines, 
compensation  clawback  policy  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  2008  Long-Term  Plan.    In  determining  the  compensation  paid  to  the  non-employee  directors,  the 
Nominating  and  Corporate  Governance  Committee  considers similar  types of  factors,  including  comparisons with 
peer companies and company performance, that are considered by the Compensation and Leadership Development 
Committee when determining executive compensation. 

During fiscal 2011, 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 $45,000 plus meeting fees of $2,000 for each board meeting 
attended in person ($1,000 if attended other than in person) and an additional $1,500 for each committee meeting 
attended in person ($750 if other than in person).  The chairs of each committee received additional annual fees for 
service as a committee chair; the chair of the Audit Committee received $15,000 and the chairs of the Compensation 
and Leadership Development Committee and the Nominating and Corporate Governance Committee each received 
$10,000.  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.  For fiscal 2012, the annual director’s 
fee will increase to $55,000, and the fee for serving as the chair of the Compensation and Leadership Development 
Committee  will  increase  to  $12,500.    Directors  are  eligible  to  defer  their  cash  fees,  as  well  as  stock  awards 
(excluding  options),  through  the  Non-Employee  Directors  Deferred  Compensation  Plan.    Prior  to  fiscal  2011, 
directors  were  eligible  to  defer  their  cash  fees  through  Plexus’  supplemental  executive  retirement  plan,  which  is 
described in “Compensation Discussion and Analysis” below. 

Directors  may  also  participate  in  the  2008  Long-Term  Plan,  which  permits  the  grant  of  stock  options, 
stock-settled  stock  appreciation  rights  (“SARs”),  restricted  stock  (which  may  be  designated  as  restricted  stock 
awards  or  restricted  stock  unit  awards),  unrestricted  stock  awards,  performance  stock  awards,  and  cash  incentive 
awards.  Stock options are generally granted to directors quarterly, at the same time as employee grants, and vest 
immediately on the respective grant dates.  The exercise price of stock options 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.  In addition, unrestricted 
stock awards are granted to directors at the same time as employee equity grants during the second quarter of the 

17 

 
fiscal year.  The mix of unrestricted stock awards and stock options is designed to balance the Company’s goal of 
aligning directors’ interests, through stock awards, with the long-term ownership interests of our shareholders with 
the incentives offered by stock options, which provide rewards based on the increase in our share price. 

The  following  table  sets  forth  the  compensation  that  was  paid  by  Plexus  to  each  of  our  non-employee 

directors in fiscal 2011:

for serving as Chairman of the Board.  See below regarding Mr. Nussbaum’s compensation. 

(2)  The  amounts  shown  represent  the  grant  date  fair  value  computed  in  accordance  with  Accounting  Standards 
Codification  Topic  718  of  stock  options  and  unrestricted  stock  awards  granted  in  fiscal  2011.    Generally 
accepted accounting principles (“GAAP”) require 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 
assumptions  used  to  determine  the  valuation  of  the  awards  are  discussed  in  footnote  11  to  our  consolidated 
financial statements.   

The following table provides cumulative information about the grant date fair value of options and stock awards 
granted  to directors  in  fiscal 2011, determined  as of  the  respective grant  dates  in  accordance  with  GAAP.   It 
also provides the number of outstanding stock options that were held by our non-employee directors at October 
1, 2011.  The Company began granting unrestricted stock awards to directors in fiscal 2010; however, restricted 
stock awards were not granted to directors in fiscal 2011 or any prior years.

Each non-employee director serving at the time was awarded options for 1,250 shares on each of November 1, 
2010, January 24, 2011, April 25, 2011, and July 25, 2011.  All options granted to non-employee directors vest 
immediately on the respective grant dates.  Options granted to non-employee directors expire on the earlier of 
(a) ten years from the date of grant, or (b) two years after termination of service as a director.  In addition, on 
January  24,  2011,  each  non-employee  director  received  an  unrestricted  stock  award  for  2,000  shares;  the 
average of the high and low trading prices of our shares on the Nasdaq Global Select Stock Market on that date 
was  approximately  $27.14.    Messrs.  Böer,  Cortinovis  and  Nussbaum  and  Ms.  Winston  each  elected  to  defer 
receipt of the 2011 unrestricted stock award. 

(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  2011  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. 

(4)  Dr. Strother did not stand for re-election at the Company’s 2011 annual meeting and, therefore, left the board on 

February 16, 2011. 

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 Committee established special retirement arrangements for Mr. Nussbaum as well as for two 
other executive officers and directors who subsequently retired.  Those arrangements were intended to both reward 
past service and maintain an additional incentive for those officers’ continued performance on behalf of Plexus.  The 
related supplemental executive retirement agreement for Mr. Nussbaum was amended in 2009 in order to align the 
agreement’s  provisions  regarding  the  determination  of  payment  amounts  to  a  fixed  15-year  annual  installment 
payment stream.  The amendment was consistent with the intent of the original agreement and with the manner in 
which the agreement operated in practice.  The arrangements are designed to provide specified retirement and death 
benefits to Mr. Nussbaum in addition to those provided under the 401(k) Plan.  Plexus’ commitment was funded in 

19 

 
 
fiscal 2002 and prior years.  Mr. Nussbaum has received payments under the special retirement arrangements since 
2002, including payments of $325,635 for fiscal 2009, $338,660 for fiscal 2010 and $352,742 for fiscal 2011.    

The contributions for Mr. Nussbaum’s special retirement arrangement are invested in life insurance policies 
acquired  by  Plexus  on  his  life.    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 a fee of $75,000 
in fiscal 2011 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.  Since his retirement, Mr. Nussbaum has 
been  eligible  to  receive  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.  Currently, all 
of our directors are in compliance with 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 2011 our insiders have complied with all Section 16(a) filing requirements that were applicable to them 
with  the  following  exceptions.    Mr.  Foate  and  Joseph  E.  Mauthe,  Plexus’  Senior Vice  President  – Global  Human 
Resources,  each  timely  reported  the  vesting  of  restricted  stock  units  on  November  5,  2010,  but  reported  the 
withholding of a portion of the shares received upon such vesting for tax purposes late.  The related transactions by 
Messrs.  Foate  and  Mauthe,  which  involved  3,746  shares  and  204  shares,  respectively,  were  each  reported  on 
December 23, 2010.

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. 

Executive Summary 

Executive Compensation Philosophy, Goals and Process 

The  Committee’s  philosophy  is  to  fairly  compensate  all  employees,  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  employee.    Compensation  packages  should  also  motivate  executives  to  make 
decisions  and  pursue  opportunities  that  are  aligned  with  the  interests  of  our  shareholders  while  not  exposing  the 
Company  to  inappropriate  risk.    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: 

•
•

•

•

attracts, motivates and retains the talent needed to lead a strong global organization; 
drives  global  financial  and  operational  success  that  creates  shareholder  value  without 
encouraging inappropriate risk-taking; 
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. 

Overview of Executive Compensation and Benefits 

Plexus  uses  the  following  compensation  reward  components  working  together  to  create  competitive 

compensation arrangements for our executive officers:   

Reward Component 

Base Salary 

Purpose

Base salary is intended to provide compensation which is not “at risk”; however, salary 
levels and subsequent increases are not guaranteed.  Our base salaries are designed to 
offer  regular  fixed  compensation  for  the  fulfillment  of  the  duties  and  responsibilities 
associated with the job roles of our executives and employees.  They are also important 
because  they  present  a  starting  point  for  considering  compensation  when  we  seek  to 
attract and retain talented individuals. 

21 

 
 
Reward Component 

Annual Incentive 

Long-Term Incentives 

Benefits

Retirement Plans 

Agreements 

Purpose

Our  annual  cash  incentive  compensation  plan,  the  Variable  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 and/or  team  objectives.  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.    The  design  of  the  VICP  offers 
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.    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.  As it applies to executive officers, the VICP is now a sub-plan of 
the 2008 Long-Term Plan. 

A  substantial  part  of  compensation,  which  is  also  at  risk,  is  long-term  equity-based 
compensation, typically awarded in the form of stock options and restricted stock units 
(“RSUs”) under the 2008 Long-Term Plan.  Our long-term incentives are designed to tie 
a major part of our key executives’ total compensation opportunities to Plexus’ market 
performance and the long-term enhancement of shareholder value, as well as encourage 
the long-term retention of these executives. 

The  health  and  well-being  of  our  employees  and  their  families  is  important  to  us.  
Therefore, we provide all of our employees in the United States with various benefits, 
such as health and life insurance.  Offering these benefits also assists the Company in 
attracting, as well as retaining, executive officers and key personnel. 

The  Company  maintains  retirement  plans  to  help  our  employees  provide  for  their 
retirement on a tax-advantaged basis.  Offering retirement plans helps the Company to 
attract  and  retain  qualified  employees,  as  well  as  meet  competitive  conditions.    The 
401(k) Plan includes a Plexus stock fund as one of its choices to permit employees to 
maintain  Plexus  ownership  if  they  wish.    The  Company  also  provides  a  supplemental 
executive  retirement  plan  under  which  certain  executive  officers  may  elect  to  defer 
some or all of their compensation and the Company makes additional contributions on 
their behalf. 

Only our Chief Executive Officer has an employment agreement, which is intended to 
help assure the continuing availability of his services over a period of time and protect 
the Company from competition post-employment.  All executive officers have change 
in control agreements to help assure that they will not be distracted by personal interests 
in  the  case  of  a  potential  acquisition  of  Plexus  and  to  assist  in  maintaining  their 
continuing loyalty. 

At Plexus’ 2011 annual meeting of shareholders, the Company held its first shareholder advisory vote on 
executive compensation.  Over 96% of shares voting supported the proposal and, therefore, the advisory resolution 
regarding executive compensation was approved.  Although the vote was non-binding, the Company, the board of 
directors  and  the  Committee  all  pay  close  attention  to  communications  received  from  shareholders  regarding  the 
Company’s  executive  compensation  policies  and  decisions.    The  Committee  reviewed  the  results  of  the  vote  and 
considered  the  high  approval  rate  as  an  indication  that  shareholders  generally  support  the  Company’s  executive 
compensation philosophy, program and decisions.

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  VICP  and  long-term  equity-based  awards  under  the  2008  Long-Term  Plan.    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. 

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 45% to 60% of base salary in fiscal 2011 with 
the opportunity to earn cash incentives beyond those levels if company financial goals were exceeded.  In the case of 
the CEO, the potential target compensation at risk as a percentage of base salary was 100%, reflecting his overall 
greater responsibility for the Company.  Long-term incentives for 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 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.

Base salary adjustments and equity awards are generally targeted for implementation in the second quarter 
of each fiscal year.  The Committee believes this timing aligns employee rewards with the Company’s processes to 
evaluate employees’ performance and forges a strong link between performance and pay. 

The resulting total targeted direct compensation mix used for fiscal 2011 for the Chief Executive Officer 
and the other executive officers named in the Summary Compensation Table herein (the “named executive officers”) 
is illustrated in the charts below:

Structure.  The  Company  and  the  Committee  review  market-based  comparisons,  peer  group  analysis  and 
other  third-party  survey  data  as  reference  points  for  compensation  practices  as  well  as  sources  of 
comparative  information  to  assist  in  establishing  appropriate  base  salaries  for  its  executive  officers.  
Through  this  form  of  benchmarking,  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  Committee 
expects  to  make  determinations  of  base  salary  adjustments  for  our  executive  officers  in  December  2011 
after  it  has  reviewed  and  considered  the  analysis  discussed  above  in  “Corporate  Governance–Board 
Committees–Compensation  and  Leadership  Development  Committee–Overview  of  the  Compensation 
Decision-Making Process–Use of Consultants.”  The effective date of any base salary adjustment for our 
executive officers is generally targeted for January in order to be aligned with the Company’s other U.S. 
salaried employees.    

23 

 
Factors  Considered  in  Determining  Base  Salary.  Prior  to  establishing  base  salary  increases  for  the  CEO 
and  approving  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.    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.  The Committee also considers the individual executive officers’ duties and 
responsibilities and their relative authority within Plexus. 

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. 

Executive officer base salary increases may include the following two components: 

–

Competitive  Adjustments.    If  executive  officer  salaries  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. 

– Merit Increases.  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 
separate merit increase may be provided based on individual performance, if appropriate.   

2011 Base Salary Adjustments.  Base salary adjustments for fiscal 2011 were approved by the Committee 
in December 2010.  For fiscal 2011, the Committee approved a base salary adjustment of $25,000 for the 
CEO, a 3.2% increase from his fiscal 2010 base salary, to $800,000.  As a result of that adjustment, our 
CEO’s  salary  is  near  the  intended  50th  percentile  of  peer  group  and  market  comparisons;  the  salary  was 
approximately  7%  above  the  50th  percentile  in  the  market  comparison,  but  was  8%  below  the  50th 
percentile  in  the  peer  group  comparison.    The  Committee  believed  this  increase  to  be  appropriate, 
particularly  in  view  of  the  Company’s  strong  financial  performance  in  fiscal  2010  and  the  fact  that  the 
CEO’s total compensation is more heavily weighted toward performance-based compensation than the total 
compensation of our other executive officers.  Our CEO’s base salary is also higher than that of our other 
executive officers because of his more extensive and challenging duties and responsibilities.

Increases  for  the  other  executive  officers  varied  from  3.6%  to  20.7%  and  reflected  the  factors  discussed 
above; the smaller adjustments reflected merit increases for performance over the past year when salaries 
were  otherwise  in  line  with  the  market  while  larger  increases  represented  a  combination  of  competitive 
adjustments,  merit  increases  and,  in  certain  cases,  increases  in  responsibilities.    In  addition,  Mr.  Lim’s 
compensation and benefits package also reflects regional survey data of the Asian markets. Other variations 
between  the  executive  officers  reflect  competitive  conditions  and  the  Committee’s  view  of  the  executive 
officers’  duties,  responsibilities  and  performance. Presented  below  are  the  fiscal  2011  base  salaries  and 
percentage increases as compared to fiscal 2010 for our named executive officers:

variation in currency exchange rates, the increase in base salary measured in MYR was 6.5%. 

Annual Incentive 

Plan Structure. The VICP provides annual cash incentives to approximately 3,200 participants, including 
our CEO and other executive officers.  For executive officers, beginning in fiscal 2011, the VICP is a sub-
plan  of  the  2008  Long-Term  Plan.    The  award  opportunity  levels  for  each  participant  are  expressed  as  a 
percentage  of  base  salary.    For  example,  in  fiscal  2011  the  targeted  award  opportunity  for  the  CEO  was 
100% of base salary, and the targeted award opportunities for other executive officers varied from 45% to 
60% of base salaries; the award opportunities for non-executive officer participants varied from 3% to 45% 
of base salaries.  The targeted award opportunities for executive officers other than our CEO increased in 
fiscal 2011, generally by ten percentage points, as a result of adjustments for market competitiveness and, 
in certain cases, increases in responsibilities.  In addition, offering a greater percentage of compensation at 
risk was intended to further align executive compensation with Company performance and the interests of 
shareholders.  Our CEO and other executive officers also have the opportunity to earn above their targeted 
award  opportunities  based  on  the  achievement  of  corporate  financial  goals.    Higher  levels  of  duties  and 
responsibilities  within  Plexus  lead  to  higher  cash  incentive  opportunities  under  the  VICP  because  the 
Committee believes that the higher the level of responsibility, the more influence the individual can have 
on  corporate  performance.    In  addition,  competitive  factors  make  relatively  higher  reward  possibilities 
important  for  those  positions.    For  each  executive  officer,  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  table  below  lists  the  fiscal  2011  targeted  VICP  award  opportunities  for  the 
named executive officers, expressed as a percentage of base salary:

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  payout  levels”  beyond  which  no  further  payment  is  earned.    The  payout  at  the 
“maximum payout 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.   Payments  to participants  are not  permitted 
under the VICP unless the Company achieves net income for the plan year. 

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 2011.   

2011 Plan Design – Company Goals. The specific corporate financial goals for fiscal 2011, 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 

25 

 
key financial metrics that the Company used internally to measure its ongoing performance and that it used 
in  its  financial  plans.    Our  fiscal  2011  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 payout” levels of achievement as part of that process.  

For the purposes of the VICP, ROCE is defined as annual operating income before taxes 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 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 “target” level are calculated by straight-line interpolation, as are awards 
between the “target” level and the “maximum payout” level. 

For fiscal 2011, in accordance with Plexus’ strategic plan, the Committee set performance levels for each 
metric with a focus on achieving our enduring financial goals—15% organic revenue growth and ROCE of 
500 basis points above our weighted average cost of capital (“WACC”)—using the philosophy below:  

Threshold

Consistent with target revenue 
growth and planned 
investments 

Maximum Payout 
(Enduring Goals) 

15% revenue growth 

Equal to Plexus’ WACC plus 
500 basis points 

We  believe  that  setting  the  maximum  payout  levels for revenue  and  ROCE  consistent  with  our  enduring 
financial  goals  fully  aligns  employees  with  the  financial  results  that  deliver  value  to  our  shareholders.  
Threshold levels for both metrics were set at the minimum levels of performance at which Plexus believes 
it  begins  generating  value  for  our  shareholders.  Target  levels  for  revenue  and  ROCE,  which  were  set 
between  the  threshold  and  maximum  payout  levels,  were  intended  be  aggressive,  yet  achievable,  to 
incentivize  growth,  but  also  deter  inappropriate  risk-taking.    The  2011  revenue  target  represented 
approximately  10%  growth  over  2010  revenue;  the  2011  ROCE  target  was  below  the  level  achieved  in 
fiscal 2010 to recognize the higher levels of capital investment and working capital planned for fiscal 2011.  
The  Committee  felt  these  performance  levels  were  challenging,  but  achievable,  based  on  industry 
conditions and Plexus’ financial plan. 

The  following  table  sets  forth  the  fiscal  2011  financial  targets  and  potential  VICP  payout  amounts  (as  a 
percent  of  targeted  VICP  cash  incentive)  for  the  named  executive  officers,  at  the  threshold,  target  and 
maximum  payout  performance  levels.    In  accordance  with  the  VICP,  the  ROCE  targets  excluded  the 
impacts of restructuring charges and equity-based compensation costs.

In fiscal 2011, revenue was $2,231 million and ROCE was 17.9%.  Therefore, the Company’s performance 
was between the target and maximum payout levels for revenue and between the threshold and target levels 
for  ROCE;  thus,  Plexus  paid  awards  to  executive  officers  and  other  employees  based  on  those  two 
components.  As a consequence, total payments based on revenue and ROCE represented 70.6% versus the 
target of 80% for corporate financial performance. Plexus’ actual performance in fiscal 2011 as compared 
to these performance levels is illustrated by the following graph:

2011 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 work as part of a team to focus on 
an objective.  Attainment of the individual objectives represents 20% of the potential targeted VICP award; 
however, no such award may be earned based on individual objectives unless the Company achieves net 
income for the plan year.  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.   

Achievement  of  individual  objectives,  for  which  there  was  a  potential  payout  equivalent  to  20%  of  the 
“targeted”  award,  varied  among  the  other  named  executive  officers  from  72.8%  to  75.1%  of  the 
individual’s potential payout for personal objectives, with the CEO achieving 87.0%.  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  award  percentage  levels  based  on  the 
achievement by each executive officer of his or her individual objectives. 

The following are summaries of the individual objectives for our named executive officers in fiscal 2011:   

– Dean A. Foate:  Mr. Foate’s individual objectives related to:  designing strategies to support 
global expansion and to expand the Company’s engineering solutions business; implementing 
branding  strategies  to  more  effectively  communicate  Plexus’  value  proposition  in  the 
marketplace;  refining  the  Company’s  crisis  management  strategies;  and  sharpening  the

Long-Term Incentives 

Plan Structure.  Total compensation, consistent with practices in our industry, places a particular emphasis 
on equity-based compensation.  The shareholder-approved 2008 Long-Term Plan allows for various award 
types,  including  options,  SARs,  restricted  stock,  RSUs,  unrestricted  stock  awards,  performance  stock 
awards and cash incentive awards.  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.  
The Committee’s policy is to not “back-date” equity grants and no equity grant was “back-dated” in fiscal 
2011.    The  reported  values  of  the  long-term  incentive  opportunities  under  equity  plans  can  vary 

28 

 
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.   

The Committee’s long-term incentive strategy allows for use of a portfolio approach when granting awards.  
For  fiscal  2011  the  Committee  used,  and  going  forward  the  Committee  intends  to  continue  using,  a 
combination of stock options and RSUs.  Prior to fiscal 2011, the Committee also granted long-term cash 
awards, which served as a stable retention incentive of a known value.  In order to more strongly align all 
long-term  incentives  with  the  Company’s  overall  performance  and  the  interests  of  shareholders,  the 
Committee  discontinued  the  use  of  long-term  cash  awards  beginning  in  fiscal  2011,  and  somewhat 
increased the number of RSUs to provide equivalent value. 

The  Committee  intends  that  each  element  of  the  portfolio  addresses  a  different  aspect  of  long-term 
incentive compensation, as set forth below:  

–

Stock options provide rewards based upon the appreciation in value to shareholders, as measured 
by the increase in our share price, and there is no value to these awards if our share price does not 
increase.

– 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, which may occur over a 
short period of time. 

–

For  non-executives  and  key  employees  who  are  eligible  for  equity  awards,  Plexus  uses  a 
distribution  weighted  toward  stock-settled  stock  appreciation  rights  (“SARs”).    Stock-settled 
SARs provide rewards  based  upon  the appreciation  in value  to  shareholders as  measured by  the 
increase in our share price while promoting employee share ownership.  Stock-settled SARs also 
allow the Committee to preserve shares available under the plan and minimizes dilution.  

The allocation formulas used in fiscal 2011 for executive officers and other non-executive employees 
receiving equity grants are illustrated in the charts below:

Annual  Award  Determination  and  Allocation  Process.    Each  year  the  Committee  is  presented  a 
recommended  total  pool  of  options,  stock-settled  SARs  and  RSUs  to  be  awarded  to  eligible 
participants.    The  Committee  reviews  the  estimated  cost  of  the  pool  and  the  recommended  grant 
guidelines  prior  to  making  grants.    Pursuant  to  its  portfolio  approach,  the  Committee  distributes  the 
entire value of each grant among the three types of awards—options, stock-settled SARs and RSUs—
as shown above.  The awards are valued at their Black-Scholes fair-market value when making these 
determinations.  For  current  executive  officers,  the  Committee  uses  a  distribution  formula  weighted 
toward stock options, so as to particularly promote increasing shareholder returns.   

29 

 
The Committee determines the grants for the CEO and other executive officers. The CEO provides the 
Committee  with  initial  grant  recommendations  for  each  executive  officer  other  than  himself.    The 
Committee determines the grant value for each executive officer by balancing the need to provide fair 
compensation  with  the  desire  to  keep  related  compensation  expense  relatively  stable  from  period  to 
period.    When  making  individual  grants,  the  Committee  considers  each  executive  officer’s  duties, 
responsibilities  and  performance.    Those  in  positions  with  more  responsibility  tend  to  receive  larger 
grants 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, as well 
as  the  accumulated  value  analysis,  to  balance  the  level  of  existing  awards  with  the  desire  to  reward 
performance and to provide retention incentives. 

For fiscal 2011, options for 82,000 shares and 32,800 RSUs were granted to the CEO, and options for 
143,250 shares and 58,800 RSUs were granted to the other executive officers as a group.  

Equity awards, consisting of stock-settled SARs and RSUs, are also allocated to high-performing key 
employees based upon recommendations by executive officers in accordance with a grant range grid, 
which assigns a range of grant sizes to each employee responsibility level. 

Basis  for  Determination  of  Timing  of  Grants.    The  Committee  makes  quarterly  stock  option  and  stock- 
settled SARs grants rather than annual grants due to the volatility of the stock market and of Plexus’ stock 
in particular.  Granting stock options and SARs all on one date in the year can make the strike price, its 
related  expense,  and  the  opportunity  it  represents  to  employees  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 dates will occur three 
days subsequent to the release of quarterly earnings, not including the day of the release.  The Committee 
uses future dates, as is permitted by the 2008 Long-Term Plan, because that minimizes the opportunity to 
choose a date based upon market performance known or knowable at the time of determination.  The 2008 
Long-Term Plan provides that the exercise price of a stock option is not permitted to be less than the fair 
market  value  on  the  stock  option  grant  date.    New  hire  option  and  stock-settled  SAR  grant  levels  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 are generally made once a year during the fiscal second quarter.  The Committee did not 
make  any  special  retention-related  grants of  RSUs  in  fiscal  2011,  as  the Committee  continued  to  believe 
that the fiscal 2009 retention-related grants of RSUs had their intended retention effect and, therefore, no 
additional special grants were necessary. 

2011 Awards.  Based on the Committee’s long-term incentive strategy as well as individual responsibility 
and  performance  considerations,  and  reflecting  all  of  the  grants  discussed  above,  in  fiscal  2011,  the 
Committee made total grants of options and RSUs to the named executive officers as follows:

Equity  Ownership  Guidelines. To  complement  the  2008  Long-Term  Plan’s  goal  of  increasing  the  alignment 
between  the  interests  of  management  and  shareholders,  the  Committee  adopted  executive  stock  ownership 
guidelines. These guidelines require our CEO to own Plexus stock with a market value equal to at least three times 
his  annual  base  salary;  executive  officers  other  than  our  CEO,  including  the  named  executive  officers  in  the 
“Summary Compensation Table” below, are required 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 or awarded while an executive 
officer  until  the  ownership  requirement  is  met;  there  are  exceptions,  including  financing  the  exercise  of  stock 
options and any applicable taxes when the shares will be held or with prior approval under special circumstances.  
All  officers  are  in  compliance  with  the  procedural  requirements  of  the  guidelines,  while  five  of  our  officers, 
including our CEO, have met the ultimate ownership amounts required by the guidelines.  

Clawback  Policy.    The  board  of  directors  adopted  the  Plexus  Corp.  Executive  Compensation  Clawback  Policy, 
effective November 2010.  Pursuant to the policy, in the event of a material restatement of the Company’s financial 
results as a result of significant non-compliance with financial reporting requirements, the Committee will review 
incentive compensation that was paid to the Company’s executive officers under the VICP (or any successor plan 
thereto) based solely on the achievement of specific corporate financial goals (“covered compensation”) during the 
period of the restatement.  If any covered compensation would have been lower had the covered compensation been 
calculated  based  on  the  Company’s  restated  financial  results,  the  Committee  will,  as  and  to  the  extent  it  deems 
appropriate, recoup any portion of covered compensation paid in excess of what would have been paid based on the 
restated  financial  results.    The  Committee  may  seek  the  recovery  of  covered  compensation  for  up  to  three  years 
preceding the date on which the Company is required to restate its financial results. 

This policy applies in addition to any right of recoupment against the Company’s Chief Executive Officer and Chief 
Financial Officer pursuant to the Sarbanes-Oxley Act of 2002.  The policy does not apply in any situation where a 
restatement  is  not  the  result  of  significant  non-compliance  with  financial  reporting  requirements,  such  as  any 
restatement  due  to  a  change  in  applicable  accounting  rules,  standards  or  interpretations,  a  change  in  segment 
designations or the discontinuance of an operation. 

Anti-Hedging  Policy.    In  August  2011,  the  Company  revised  its  Insider  Trading  Policy  to  explicitly  prohibit 
directors, officers and employees from engaging in transactions designed to hedge or offset a decrease in the price of 
the  Company’s  common  stock.    Short  sales  of  the  Company’s  securities  are  also  prohibited  under  the  Insider 
Trading Policy. 

Elements and Analysis of 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 benefits, retirement plans 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. 

Benefits

Structure.  We generally provide health and welfare 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. 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.  The other benefits for certain of our executive 
officers are: a flexible perquisite benefit valued at up to $15,000 per calendar year to be used for 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 life and disability insurance 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  as  well  as  to  executive  officers  who  may  be 
temporarily assigned outside of the United States.

Retirement Planning – 401(k) Plan

Structure.    The  401(k)  Plan,  which  is  available  to  substantially  all  U.S.  salaried  employees,  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 
$9,800  per  calendar  year  (increasing  to  $10,000  in  calendar  year  2012).    Employees  have  a  choice  of 
investment alternatives, including a Plexus stock fund, in which to invest those funds. 

Retirement Planning – Supplemental Executive Retirement Plan 

Structure.  As  a  consequence  of  Internal  Revenue  Code  limitations  on  compensation  which  may  be 
attributed  to  tax  qualified  retirement  plans  (such  as  the  401(k)  Plan),  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’ supplemental executive retirement plan 
(the “SERP”) is a deferred compensation plan which allows participants to defer taxes on current income.  
Under  this  plan,    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.  The plan 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,  retirement  from  Plexus, or in  accordance with 
the executive’s individual deferral election. 

All  executive  officers,  other  than  Mr.  Lim,  participate  in  this  program.    Additionally,  the  Company  can 
credit  a  participant’s  account  with  a  discretionary  employer  contribution.  Any  employer  contributions  to 
the  SERP  require  Board  approval.    The  SERP  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  these  limitations  make 
supplemental  retirement  plans  common  practice  in  general  industry.    The  Committee  also  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. 

Fiscal 2011 Plan Activity. 

– Contribution Formula.  Under a funding plan adopted by the Committee, the SERP provides for an 
annual  discretionary  contribution  of  the  greater  of  (a) 7%  of  the  executive’s  total  targeted  cash 
compensation  (increased  to  9%  beginning  in  August  2011,  as  described  below),  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 cash 
incentive 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  Watson,  its 
compensation consultant for that program. In fiscal 2011, at the request of the Committee, Towers 
Watson  conducted  a  competitive  analysis  of  the  contribution  formula.    While  the  contribution 
formula was found to reasonable, it was determined to be slightly lower than current competitive 
practice.  Therefore, the Committee decided to increase the Company contribution from 7% to 9% 
of the executive’s total targeted cash compensation, beginning in August 2011, in order to be more 
in line with current market practice.

–

Employer Contributions.  For fiscal 2011, the total employer contributions to the SERP accounts 
was $280,534 for all participants as a group, including $108,768 for the CEO.  See footnote 4 to 
the “Summary Compensation Table.”

32 

 
–

Special Contribution.  The SERP also allows the Committee to make discretionary contributions 
over and above the annual contribution noted above.  In fiscal 2011, the Committee did not make 
any such contributions to any of the executive officers, including the named executive officers.  

Fiscal 2012 Payment Schedule.  The annual contribution made by the Company will be paid throughout the 
year on a bi-weekly basis.  This schedule allows for dollar cost averaging and spreads the expense of the 
contribution across the fiscal year.  If necessary, a true-up payment will  be made at the end of the fiscal 
year if the Company contribution for any executive officer is less than $13,500. 

Foreign Retirement 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 2011 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.

Employment and Change in Control Agreements 

Structure.  We do not generally have employment agreements with our executive officers; however, Plexus 
does  maintain  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 and 
certain other key employees have change in control agreements (with the exception of Mr. Foate, who has 
change  in  control  provisions  as  part  of  his  employment  agreement),  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.  We also believe that competitive factors require us to provide these 
protections to attract and retain talented executive officers and key employees.

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. 

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  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.  In addition, under the 2008 
Long-Term Plan (and its predecessor) 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    or  two  years’  of  coverage.    In  determining  which 
employees should have change in control agreements, the Committee utilizes its guidelines, which focus on 
position, responsibilities and compensation level in order to minimize subjectivity. 

The Committee originally set these benefit levels in 2008, when the agreements were updated and revised, 
and  reviews  them  annually.    It  is  the  Committee’s  view  that  the  level  of  benefits,  combined  with  the 
“double  trigger”  requiring  both  a  change  in  control  and  a  termination  of  employment,  provides  an 
appropriate balancing of the interests of the Company, its shareholders and its executives.   Benefit levels 
are  believed  to  be  both  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.    The 
Committee believes it is 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 its predecessor), as approved by Plexus’ 
shareholders.  Therefore, offering a package that is consistent with market practices, is appropriate to help 
motivate executives to focus on the Company’s shareholders, even when the circumstance might jeopardize 

33 

 
their employment.  The Committee also intends that the potential expense of the agreements is reasonable 
as  compared  to  total  enterprise  value.    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;  potential  expense  was  estimated  at  2.6%  of  total  enterprise  value  as  of  the  date  of  the 
Committee’s most recent determination.  As noted above, the agreements contain a “double trigger,” which 
provides that benefits would only be paid to the executive officers in the event of a substantial impact upon 
their employment and compensation. 

The  Committee  periodically  reviews  the  scope  and  context  of  the  change  in  control  agreements.  The 
Committee continues to believe, as noted above, 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  incentive  awards,  including  those  made  to  executive  officers 
pursuant  to  the  VICP,  under  the  2008  Long-Term  Plan  (and  predecessor  plans)  is  exempt.    Compensation  under 
these  shareholder  approved  plans  that  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), 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 since fiscal 2008) would not be subject to the Code’s deduction limitation.  
However, if such restricted stock awards are made, the covered compensation of some individuals could exceed $1 
million  and,  in  those  cases,  the  excess  would  not  currently  be  tax  deductible.    In  some  years,  the  Company  has 
foregone  a  portion  of  its  tax  deduction  as  a  result  of  the  size  of  VICP  cash  incentive  payments.    However,  to 
ameliorate  those  tax  consequences,  the  Company  sought  and received  shareholder  approval  of  the  amendment  to, 
and restatement of, the 2008 Long-Term Plan at the 2011 annual meeting so that VICP awards to executive officers 
may be granted under that plan; therefore, in fiscal 2011, such deduction was not foregone. 

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 also provides 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 
became fully effective on January 1, 2009.  We 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  made  various  changes  to  some  of  these  plans  and 
arrangements to ensure full compliance with the 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”),  the  Plexus  supplemental  executive  retirement  plan  (the  “SERP”)  and,  for  Mr.  Lim,  the 
Malaysian  Employees  Provident  Fund.    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 2011, fiscal 2010 and fiscal 2009, respectively, under our Variable Incentive Compensation 
Plan (“VICP”).  Under the VICP, annual cash incentives 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  in  fiscal  2010  and  fiscal 
2009,  it  is  in  the  “Bonus”  column.    To  the  extent  that  the  cash  incentive  resulted  from  corporate  financial 
performance, and, for fiscal 2011, individual objectives, that portion of the cash incentive 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 “2011” row were earned in fiscal 2011 but 
will be paid in fiscal 2012, the amounts shown in the “2010” row were earned in fiscal 2010 and were paid in 
fiscal 2011, and the amounts shown in the “2009” row were earned in fiscal 2009 and were paid in fiscal 2010.  
The amounts in the “Non-Equity Incentive Plan Compensation” column for fiscal 2010 and 2009 also include 
the  value  of  long-term  cash  awards  granted  in  those  years,  which  vest  on  the  third  anniversary  of  their 
respective grant dates; no equivalent grants were made for fiscal 2011. 

36 

 
(3)  This  column  represents  the  grant  date  fair  value  computed  in  accordance  with  Accounting  Standards 
Codification Topic 718 (“ASC 718”) of stock and option awards granted in fiscal 2011, fiscal 2010 and fiscal 
2009  under  the  2008  Long-Term  Plan,  which  are  explained  further  below  under  “Grants  of  Plan-Based 
Awards.”  These awards are not subject to performance conditions.  Generally accepted accounting principles 
(“GAAP”)  require  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  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  stock  and 
option  awards  granted  in  fiscal  2011,  and  the  “Outstanding  Equity  Awards  at  Fiscal  Year  End”  table  below 
relating to all outstanding stock and option awards at the end of fiscal 2011. 

(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 benefit provided to the executive, additional life and disability insurance 
coverage and benefits related to an overseas assignment.  Per person detail is listed in the table below:

Mr. Foate 

Ms. Jones 

Mr. Buseman 

Mr. Kelsey 

Mr. Lim 

In  fiscal  2009  and  essentially  all  of  the  first  quarter  of  fiscal  2010,  under  the  executive  flexible  perquisite 
benefit,  executive  officers  could  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.    Beginning  January  1,  2010,  the 
executive flexible perquisite benefit was valued at up to $15,000 per calendar year, but the gross-up for taxes 
was  eliminated.    The  amounts  in  the  “Executive  Flexible  Perquisite  Benefit”  column  above  include  the 
reimbursements under that program in the fiscal years listed, including the related tax gross-up amounts; these 
amounts may exceed the calendar year limits due to the tax gross-up and the difference between the fiscal and 
calendar year. 

Ms.  Jones  was  on  a  temporary  assignment  for  Plexus  in  Malaysia  for  a  portion  of  fiscal  2011.    The  amount 
reported above in the “Overseas Assignment” column reflects benefits related to this assignment beyond those 
that were integral and necessary to the business purpose of the assignment, including expenses for a rental car 
for her spouse, as well as the related tax gross-up, and a $15,000 overseas allowance, which amount was not 
grossed up for taxes.

(5)  Although Mr. Kelsey has been an executive officer since 2007, he was a named executive officer for the first 
time in fiscal 2010.  In accordance with SEC rules, information for fiscal 2009 is not required to be presented.

GRANTS OF PLAN-BASED AWARDS 
2011 

The following table sets forth information about stock and option awards that were granted to the named 
executive officers in fiscal 2011 under the 2008 Long-Term Plan, as well as information about the potential cash
incentive awards dependent on quantifiable corporate performance and individual goals that those executive officers 
could  earn  for  fiscal  2011  performance  (to  be  paid  in  fiscal  2012)  under  the  VICP.    As  a  result  of  fiscal  2011 
corporate  performance,  cash  incentive  awards  based  on  these  criteria  were  earned  in  2011,  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 in fiscal 
2011 in the table below, and additional information about those plans following the table.

*  Represents  a  potential  cash  incentive  payment  for  fiscal  2011  at  various  performance  levels  under  the  VICP 
(amounts in the “Maximum” column correspond to the “maximum payout level” under the VICP); other grants 
are stock options and restricted stock units (“RSUs”) under the 2008 Long-Term Plan.  As a result of Plexus’ 
actual  performance  in  fiscal  2011,  overall  cash  incentive  awards  were  earned  based  on  corporate  financial 
performance  between  the  threshold  and  target  levels,  as  reflected  in  the  “Summary  Compensation  Table”  and 
discussed in “Compensation Discussion and Analysis” above. 

(1) Amounts in the rows labeled “VICP*” reflect potential cash incentive payments that depend on Plexus meeting 
corporate  financial  goals  and  the  named  executive  officers  achieving  individual  objectives  (assuming  such 
officers do not meet any of their individual objectives at “Threshold” and meet them fully at both “Target” and 

38 

 
the “maximum payout level”).  The amounts in the “Threshold” column indicate a payment for performance just 
above the threshold; there is no minimum payment once the threshold has been exceeded. 

(2) Options were granted  at  the average  of  the  high  and  low  trading  prices  on  the date  of 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 that were granted in 
fiscal 2011 under 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  January  24,  2014,  assuming  continued  employment.  See  the  discussions  below  under  the 

caption “2008 Long-Term Plan.” 

VICP

Beginning in fiscal 2011, the VICP (as it applies to our executive officers) is now a sub-plan of the 2008 
Long-Term Plan.  Under the VICP, our executive officers may earn cash incentive awards that depend in substantial 
part  upon  the degree  to  which  Plexus  achieves  corporate financial  goals,  which  are  set  by  our  Compensation  and 
Leadership Development Committee (the “Committee”) shortly after the beginning of our fiscal year.  As long as 
Plexus  achieves  net  income  for  the  plan  year,  each  executive  officer  also  may  earn  a  portion  of  his  or  her  cash 
incentive award by accomplishing the individual objectives set for that executive officer.  These awards are intended 
to reflect, in each instance, an individual’s performance that may not be reflected in the financial performance of the 
entire Company.  The amounts included in the table are potential future payouts under non-equity incentive awards 
that could be earned pursuant to both corporate financial and individual 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 met exactly at the targeted level and the maximum amount that could be earned under the 
VICP, which is known as the “maximum payout level.”  As noted above, the potential payouts reported in the table 
assume  that  the  named  executive  officers  do  not  meet  any  of  their  individual  objectives  at  threshold  and  achieve 
them fully at both target and the maximum payout level. 

Actual  Company  performance  in  fiscal  2011  was between  the  target  and  the  maximum  payout  levels  for 
revenue and was between the threshold and target levels for return on capital employed (“ROCE”); thus, total cash 
incentives based on corporate financial goals were paid between the threshold and target levels, as reported in the 
“Non-Equity Incentive Compensation” column in the “Summary Compensation Table” above. 

The maximum amount that could be earned based on individual performance was $158,654 for Mr. Foate 
(which would have been 20% of his cash incentive award at the targeted levels) and varied from $33,584 to $43,017 
for the other named executive officers (also representing 20%). 

2008 Long-Term Plan

Under the 2008 Long-Term Plan, the Committee 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, unrestricted stock awards, performance stock awards (which may be settled in cash 
or  stock)  and  cash  incentive  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 
grant  schedule  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. 

The Committee grants RSUs under the 2008 Long-Term Plan.  In fiscal 2011, annual grants were made in 
January 2011, and vest three years from the date of the grant, assuming continued employment.  Going forward, the 
Committee anticipates continuing to make grants of RSUs in the second quarter of each fiscal year.

(1)  Option award under the 2008 Long-Term Plan or a 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 (and 
to Ms. Jones in April 2007) vested one-third on each of the first three anniversaries of the grant date.  Options 
granted in fiscal 2007 and after vest one-half on each of the first two anniversaries of the grant date. 

(2)  Based on the $22.62 per share closing price of a share of our common stock on September 30, 2011, the last 

trading day of fiscal 2011. 

(3)  Consists  of  RSUs  awarded  in  fiscal  2009  under  the  2008  Long-Term  Plan.  The  RSUs  vested  on  October  31,

NONQUALIFIED DEFERRED COMPENSATION 
2011 

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 executive officers.  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 75% of their annual compensation, up to a maximum 
tax code mandated limit of $16,500 ($22,000 if age 50 or older) in calendar year 2011 (increasing to up to $17,000 
and  $22,500,  respectively,  in  calendar  year  2012);  Plexus  will  match  100%  of  the  first  4.0%  of  salary  which  an 
employee defers, up to $9,800 in calendar year 2011 (increasing to up to $10,000 in calendar year 2012).  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 its executive officers; 
the individuals covered in fiscal 2011 include Ms. Jones and Messrs. Foate, Buseman and Kelsey.  Mr. Lim does not 
participate because he is not a United States resident.  Under the SERP, an 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 plan 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, including the named executive officers, did not make any personal voluntary deferrals 
to  the  SERP  for  fiscal  year  2011.    The  plan  also  allows  for  discretionary  Plexus  contributions.    As  discussed  in 
“Compensation Discussion and Analysis—-Elements and Analysis of Other Compensation—Retirement Planning - 
Supplemental  Executive  Retirement  Plan,”  in  fiscal  2011,  the  Committee  approved  an  increase  in  the  Company 
contribution to the SERP after reviewing a competitive analysis prepared by Towers Watson.  As a result, beginning 
in  August  2011,  the  discretionary  contribution  is  the  greater  of  (a)  9%  of  the  executive’s  total  targeted  cash 
compensation (increased from 7%), 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; no such 
contributions were made in fiscal 2011. 

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 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.  The Company entered into a new employment 
agreement with Mr. Foate in 2008.  The new employment agreement, which was approved by the Committee and 
the board, amended and superseded Mr. Foate’s previous employment agreement with the Company.  Changes were 
made in order to more 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 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 

45 

 
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 cash incentive award 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. 

Change  in  control  provisions  are  included  in  Mr.  Foate’s  current  employment  agreement  and  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 October 1, 2011.  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

Plexus  has  change  in  control agreements  with  Ms.  Jones  and  Messrs.  Buseman,  Kelsey  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  three  times  (one  to  two 
times  for  other  key  employees)  the  executive  officer’s  base  salary  plus  targeted  cash  incentive  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. Buseman, Kelsey 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.  It is the Committee’s view that the 
level  of  benefits,  combined  with  the  “double  trigger”  requiring  both  a  change  in  control  and  a  termination  of 
employment, provides an appropriate balancing of the interests of the Company, its shareholders and its executives. 

46 

 
Under our change in control agreements: 

•

•

•

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  October 1,  2011  (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  (generally  to  a  maximum  of  13  weeks)  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 October 1, 2011, 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 cash incentive awards to the 
extent they would be paid after termination, based on the salary in effect at the end of fiscal 2011 and the target 
VICP  cash  incentive  payment  for  2011.    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.    Outstanding  unvested  stock  options  had  no  immediately  realizable 
value because the respective exercise prices were higher than $22.62, the closing price of Plexus’ common stock 
on September 30, 2011, the last trading day of fiscal 2011. See “Outstanding Equity Awards at Fiscal Year End” 
for further information regarding all stock options owned by the named executive officers, including those that 
have already fully vested. 

(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 $22.62 per share on September 30, 2011, the last 
trading date of fiscal 2011.  As previously discussed, grants of long-term cash awards were discontinued after 
fiscal 2010. 

48 

 
(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.    Based on  Mr. Foate’s  average 
annual  compensation  and  the  manner  in  which  Section  280G  operates,  he  would  have  not  qualified  for  such 
payments had there been a change in control on October 1, 2011, but could be eligible to receive these payments 
in future years. 

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

COMPENSATION AND RISK 

During fiscal 2011, the Company reviewed its compensation policies, programs and procedures, including 
the incentives they create and mitigating factors that may reduce the likelihood of excessive risk taking, to determine 
whether they present a significant risk to the Company.  Management assessed risk factors associated with specific 
compensation programs, as well as enterprise-level compensation risk factors, and a risk rating was assigned to each 
factor.    The  program-specific  risk  factors  assessed  included  payout  potential,  payout  as  a  percentage  of  total 
compensation,  risk of  manipulation,  discretion  to  modify  awards,  overall  plan design  and  market  appropriateness.  
Enterprise-level risk factors evaluated included the balance between performance rewarded and the sustainability of 
that  performance,  the  overall  compensation  mix,  consistency  between  annual  and  long-term  objectives  as  well  as 
metrics, achievability of performance goals without undue risk-taking, the relationship of long-term awards to the 
Company’s pay philosophy, stock ownership requirements, the weighting and duration of performance metrics, the 
value of severance packages, the degree to which pay programs (including retirement benefits) and/or grants may be 
considered disproportionate, and the interaction of compensation plans with the Company’s financial performance 
and  strategy.    The  Compensation  and  Leadership  Development  Committee  reviewed  management’s  evaluation 
process as well as its results, and determined that both the process and conclusions reached were reasonable. 

Based on this review, the Company has concluded that its compensation policies, programs and procedures 

are not reasonably likely to have a material adverse effect on the Company.

ADVISORY VOTE ON EXECUTIVE COMPENSATION 

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), 
publicly-traded companies like Plexus are required to hold an advisory vote of their shareholders at least once every 
three years to approve the compensation of named executive officers, as disclosed in the company’s proxy statement 
pursuant  to  the  SEC's  Regulation  S-K  Item  402;  Plexus  discloses  those  items  in  “Compensation  Discussion  and 
Analysis” and “Executive Compensation” herein.  Plexus currently holds these votes annually. 

As  described  in  “Compensation  Discussion  and  Analysis”  above,  we  design  our  executive  compensation 
programs  to  attract,  motivate  and  retain  the  talent  needed  to  lead  a  strong  global  organization,  to  drive  global 
financial  and  operational  success,  to  create  an  ownership  mindset  and  to  appropriately  balance  Company 
performance  and  individual  contributions  towards  the  achievement  of  success.    A  meaningful  portion  of  our 
executive officers’ compensation is at risk, reflecting the Company’s emphasis on pay that reflects performance and 
drives long-term shareholder value.  We believe the Company’s compensation program as a whole is well suited to 
promote the Company’s objectives in both the short and long term. 

Accordingly,  the  following  resolution  will  be  submitted  to  our  shareholders  for  approval  at  the  annual 

meeting:  

“RESOLVED,  that  the  compensation  paid  to  the  Company’s  named  executive  officers,  as 
disclosed  pursuant  to  Item  402  of  Regulation  S-K,  including  the  Compensation  Discussion  and 
Analysis, compensation tables and narrative discussion, is hereby approved.”  

As  an  advisory  vote,  this  proposal  is  not  binding  on  the  Company.    However,  the  Compensation  and 
Leadership  Development  Committee,  which  is  responsible  for  designing  and  administering  the  Company’s 
executive compensation programs, values the opinions expressed by our shareholders, and will consider the outcome 
of the vote when making future compensation decisions on the Company’s executive compensation programs.  

The board unanimously recommends that shareholders vote FOR approval of the compensation of 

the Company’s executive officers as described in this proxy statement. 

CERTAIN TRANSACTIONS

Plexus  has  a  written  policy  requiring  that  transactions,  if  any,  between  Plexus  and  its  executive  officers, 
directors  or  employees  (or  related  parties)  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.  
See  also  “Corporate  Governance–Directors’  Compensation–Compensation  of  Current  and  Former  Executive 
Officers who Serve on the Board” regarding agreements with two directors.  There were no other transactions in an 
amount or of a nature that were reportable under applicable SEC rules in fiscal 2011. 

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 5605(a)(2) of the NASD listing standards applicable to the Nasdaq Global Select Stock 

50 

 
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. 

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: 

• 

• 

• 

reviewed and discussed the audited financial statements for the fiscal year ended October 1, 2011, 
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 October 1, 2011.  
The Audit Committee further confirmed the independence of PricewaterhouseCoopers LLP. 

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

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  2012.  
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 2011 and 2010 were as follows: 

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

      2011  

      2010

  $1,017,965 
          --   
         47,475 
          --   

  $952,300 
        -- 
      49,990 
        -- 

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 tax 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 2011 or 2010 that were not approved in advance by the 
Audit Committee under this policy.

ITEM 1. 

BUSINESS 

Overview 

PART I

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

Manufacturing Services (“EMS”) industry.  We deliver optimized Product Realization solutions through a unique 
Product Realization Value Stream services model.  This customer focused services model seamlessly integrates 
innovative product conceptualization, design, commercialization, manufacturing, fulfillment and sustaining services to
deliver comprehensive end-to-end solutions for customers in the Americas (“AMER”), European (“EMEA”) and Asia-
Pacific (“APAC”) regions.  Award-winning customer service is provided to over 130 branded product companies in the 
Wireline/Networking, Wireless Infrastructure, Medical, Industrial/Commercial and Defense/Security/Aerospace market 
sectors.  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 verification; 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 leading EMS company in the world at servicing mid-to-low 

volume, higher complexity customer programs characterized by unique flexibility, technology, quality and regulatory 
requirements.  We have aligned our business operations, processes, workforce and financial metrics to support this 
strategy.

We operate flexible manufacturing facilities and processes designed to accommodate customers with multiple 
product-lines and configurations.  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 in these sectors.  These teams also help set our strategy for growth in these 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”) 500 basis points in excess of our weighted average cost of capital (“WACC”).  We review 
our internal calculation of WACC annually, and at the end of fiscal 2011 reduced our estimated WACC to 12.5%.  
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, particularly those that provide EMS services for high-volume, less 
complex products with less stringent requirements (such as consumer electronics).  By exercising discipline to generate 
a ROIC in excess of our WACC, our goal is to ensure that Plexus creates value for our shareholders. 

Our customers include both industry-leading original equipment manufacturers (“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 

2

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 9,000 full-time employees, including 

approximately 1,700 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 24 active 
facilities in 15 locations, totaling approximately 2.6 million square feet.  These facilities are strategically located to 
support the global supply chain, manufacturing and engineering needs of customers in our targeted market sectors. 

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: 

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

services. These product design services include program management, feasibility studies, product conceptualization, 
specification development for product features and functionality, 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, fluidics, 
robotics, plastic components, sheet metal enclosures, and castings), development of test specifications and product 
verification 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, are typically configured to fulfill unique end-

3

 
  
customer requirements and many are shipped directly to our customers’ end users.  We provide a range of higher level 
assembly services to our customers; these products typically fall into one of the following categories in our assembly 
spectrum: 

•
•
•

Printed circuit board assembly – a printed circuit board (“PCB”) populated with electronic components. 
Basic assembly – a sub-assembly that includes PCBs and other components. 
System integration – a finished product or sub-system assembly that includes more complex components 
such as PCB’s, basic assemblies, custom engineered components, displays, optics, metering and 
measurement or thermal management. 

• Mechatronic integration – more complex system integration that combines electronic controls with 

mechanical systems and processes such as motion control, robotics, drive systems, fluidics, hydraulics or 
pneumatics. 

System integration and mechatronic integration products can be very large and could include products such as 
kiosks, finished medical products and complex electro-mechanical assemblies. These products often combine many of 
the other integrated services we provide and may require more unique facility configurations as well as supply chain 
solutions 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 
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 9001:2008 standards.  We have additional 

certifications and/or registrations held by certain of our facilities in the following regions: 

Environmental Standard ISO – 14001 – AMER, APAC, EMEA 
Environmental Standard OSHAS 18001 – APAC, EMEA 
21 CFR Part 820 (FDA) (Medical) – AMER, APAC 
Telecommunications Standard TL 9000  – AMER, APAC 

• Medical Standard ISO 13485:2003 – AMER, APAC, EMEA 
•

• Aerospace Standard AS9100 – AMER, APAC, EMEA 
• NADCAP certification – AMER, APAC 
•
FAR 145 certification (FAA repair station) – AMER 
•

• ANSI/ESD (Electrostatic Discharge Control Program) S20.20 – AMER, APAC 
• ATEX/IECEx certification – APAC, EMEA 
•
•

SFDA (Medical) – APAC 
JMGP accreditation – APAC, AMER, EMEA 

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 2011, we served approximately 130 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.   

4

Juniper Networks, Inc. (“Juniper”) accounted for 17 percent of our net sales in fiscal 2011, 16 percent in fiscal 
2010 and 20 percent in fiscal 2009.  No other customer accounted for 10 percent or more of our net sales in fiscal 2011, 
2010 or 2009.  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).  Our array of services for customers in each of these end 
markets is essentially the same and we do not dedicate operational equipment, personnel, facilities or other resources to 
particular end markets, nor do we internally track our costs and resources on this basis. 

Materials and Suppliers 

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

manufacturers and distributors.  In addition, under certain circumstances, we will purchase components from brokers, 
customers or competitors. 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 components, we also purchase components used in manufacturing and higher-level assembly.  These 
components include molded/formed plastics, sheet metal fabrications, aluminum extrusions, robotics, motors, vision 
sensors, motion/actuation, fluidics, displays, 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 risk of the electronics 

industry.  Components shortages have been an issue for the industry and for us in fiscal 2011 and fiscal 2010; these 
shortages are discussed more fully in “Risk Factors” in Part I, Item 1A herein.  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.  We also have a global expediting and 
escalation process that we believe provides Plexus the ability to effectively track and manage component shortages.  
Since 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 use of advanced supply chain solutions to improve 
continuity of supply and supply chain flexibility.   

New Business Development 

Our new business development is organized around end markets, or market sectors.  Each market sector has a 
team of dedicated resources including a business development vice president, a customer management vice president, 
sales account executives, customer directors, customer managers, engineering and manufacturing subject matter 
experts, and market sector analysts.  Our sales and marketing efforts focus on both targeting new customers and 
expanding business with existing customers.  We believe our ability to provide a full range of product realization 
services is a marketing advantage; our sector teams 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 EMS 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 that we use in our business; these marks are registered in the trademark offices 

of the United States and other countries.  Although we own certain patents, they are not currently material to our 
business.  We do not have any material copyrights.  

Information Technology 

Our integrated ERP platform serves all of our manufacturing sites.  This ERP platform augments our other 

management information systems and includes various software systems to enhance and standardize our ability to 
translate information from multiple production facilities into operational and financial information as well as 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. 

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 9,000 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 the United Kingdom, approximately 140 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, 
Romania, Germany, 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.

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: 

•
•
•
•
•
•
•
•
•
•

•
•

the volume and timing of customer demand relative to our capacity 
the typical short life-cycle of our customers’ products 
customers’ operating results and business conditions  
changes in our, and our customers’, sales mix 
varying gross margins among different programs 
failures of our customers to pay amounts due to us 
volatility of customer demand for certain programs and sectors 
challenges associated with the engagement of new customers or additional work from existing customers 
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 if 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 55 percent of our net sales for the fiscal year ended October 1, 2011, and   
57 percent of our net sales for the fiscal year ended October 2, 2010.  For the fiscal year ended October 1, 2011, there 
was one customer 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.  
Especially given our discrete number of customers, significant reductions in net sales to any of these customers, the loss 
of major customers or our failure to make appropriate choices as to the customers we serve could seriously harm our 
business.  

In addition, we focus our net sales to customers in only a few market sectors, and we endeavor to carefully 

choose those sectors.  Each of these sectors is subject to macroeconomic conditions as well as trends and conditions that 
are sector specific.  Shifts in the performance of a sector served by Plexus, as well as the economic and business 
conditions that affect the sector, or our failure to choose appropriate sectors can particularly impact Plexus.  For 
instance, sales in the medical sector are substantially affected by trends in that industry, such as government 
reimbursement rates and uncertainties relating to the financial health of, and pending changes in the structure of, the 
U.S. health care sector generally.  Further, potential reductions in U.S. defense spending could substantially affect our 
opportunities in our Defense/Security/Aerospace sector.  Any weakness in the market sectors in which our customers 
are concentrated could affect our business and results of operations. 

In the current economic environment, we are seeing increased merger and acquisition activity that has already 
affected, and may continue to impact, our customers. Specifically, two of our significant customers were acquired in the 
first quarter of fiscal 2010 and substantially disengaged in fiscal 2011.      

Instability in the global credit markets and continuing economic weakness may adversely affect our earnings, 
liquidity and financial condition.

Global financial and credit markets have been, and continue to be, unstable and unpredictable.  Worldwide 

economic conditions have been weak and may deteriorate further.  For example, substantial credit issues have arisen in 
the European Union as a result of the sovereign debt crisis and other factors affecting economies worldwide.  The 
instability of the markets and weakness of the economy could continue to affect the demand for our customers' 
products, the amount, timing and stability of their product demand from 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 and/or the ability of us, our customers or our suppliers 
to obtain credit.  Further, global credit market and economic challenges may affect the ability of counterparties to our 
agreements, including our credit agreement and interest rate swap agreements, to perform their obligations under those 
agreements.  These factors could adversely affect our operations, earnings and financial condition.

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

We do not have any long-term supply agreements.  At various times, including fiscal 2011, we have 
experienced raw material and component parts shortages due to supplier capacity constraints or their failure to deliver.  
Part shortages were prevalent during portions of fiscal 2011 and fiscal 2010 across the EMS industry, based on the 
relatively quick recovery of the demand for technological equipment and the resulting capacity constraints at suppliers; 
shortages have continued into, and are expected to persist in the future.  Such constraints can also be caused by world 
events, such as government policies, terrorism, armed conflict and economic recession.  In addition, the March 2011 
earthquake and tsunami in Japan disrupted the global supply chain for certain components manufactured in Japan that 
are incorporated in the products we manufacture and the flooding in Thailand during our fiscal fourth quarter of 2011 
had a similar impact.  While we have yet to experience material adverse effects resulting from these events, the 
magnitude and duration of the impact on us resulting from these events are not yet known.  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.  Some suppliers have ceased doing business due to economic or other 
circumstances, and more may do so in the future.  Supply shortages and delays in deliveries of raw materials or 
component parts have in some cases 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. 

In addition, raw material and component parts that are delivered to us may not meet our specifications or other 
quality criteria.  Certain materials provided to us may be counterfeit or violate the intellectual property rights of others.  
The need to obtain replacement materials and parts may negatively affect our manufacturing operations.  The 
inadvertent use of any such parts or products may also give rise to liability claims. 

Raw material and component part supply shortages and delays in deliveries can also result 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 repricing 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.   

Plexus is a multinational corporation and operating in multiple countries exposes us to increased risks, including 
adverse local developments and currency risks. 

We have operations in many countries; operations outside of the U.S. in the aggregate now represent a 

majority of our revenues.  We also purchase a significant number of components manufactured in various countries.  
These international aspects of our operations, which are likely to increase over time, subject us to the following risks 
that could materially impact our operations and operating results: 

•
•
•
•
•

•
•
•

economic, political or civil instability, including significant drug cartel-related violence in Juarez, Mexico 
transportation delays or interruptions  
exchange rate fluctuations 
difficulties in staffing and managing personnel in diverse cultures 
compliance with laws, such as the U.S. Foreign Corrupt Practices Act and the U.K. Anti-Bribery Act, 
applicable to companies with global operations  
significant natural disasters 
the effects of international political developments and 
regulatory requirements and potential changes to those requirements. 

We continue to monitor our risk associated with foreign currency translation and have entered into limited 

forward contracts to address this risk.  As our international 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 other 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.

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, and frequently do not have visibility as to their future 
demand.  Customers also cancel requirements, change production quantities, delay production or revise their forecasts 
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 and negatively affect our working capital levels.  
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, working capital management, 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 as well as product demand.  For example, defense procurement is 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, they may or may not result 
in continuing long-term programs or relationships.  Even in the case of continuing long-term programs or relationships, 
orders in the defense sector can be episodic, can vary significantly from period to period, and are subject to termination. 

We have a complex business model, and our failure to properly manage that model could affect our operations 
and financial results. 

Our business model focuses on products and services in the mid-to-lower-volume, higher-mix segment of the 

EMS market.  Our customers’ products typically require significant production and supply-chain flexibility, 
necessitating optimized demand-pull-based manufacturing and supply chain solutions across an integrated global 
platform.  The products we manufacture are also typically complex, highly regulated, and require complicated 
configuration management and direct order fulfillment capabilities to global end customers.  Relative to many of our 
competitors that manufacture more standardized products with larger production runs, our business model requires a 
greater degree of attention and resources,  including working capital, management and technical personnel, and the 
development and maintenance of systems and procedures to manage diverse  manufacturing, regulatory, and service 
requirements.  If we fail to effectively manage our business model, we may lose customer confidence and our reputation 
may suffer.  The Company’s reputation is the foundation of our relationships with key stakeholders.  If we are unable to 
effectively manage real or perceived issues, which could negatively impact sentiments toward the Company, our ability 
to maintain or expand business opportunities could be impaired and our financial results could suffer on a going-
forward basis.  

In addition, the complexity of our service model often results in complex and challenging contractual 
obligations as well as commitments from us to our customers.  If we fail to meet those obligations, it could affect our 
reputation and our ability to obtain future business, as well as impair our ability to enforce our rights (including those 
related to payment) under those contracts. 

Challenges associated with the engagement of new customers or programs could affect our operations and 
financial results. 

Our engagement with new customers, as well as the addition of new work for existing customers, can present 

challenges in addition to opportunities.  We must initially determine whether it would be in our interests from a 
business perspective to pursue a particular potential new customer or program, including evaluating the customer’s 
and/or program’s fit with our value proposition as well as their end market success.  If we make the decision to proceed, 
we need to ensure that our terms of engagement, including our pricing and other contractual provisions, appropriately 

9

 
 
 
 
 
 
 
reflect the anticipated costs, risks, and rewards of an opportunity. The failure to make prudent engagement decisions 
and/or to establish appropriate terms of engagement could adversely affect our profitability and margins.   

Also, there are inherent risks associated with the timing and ultimate realization of a new program’s 

anticipated revenue; these factors can sometimes extend for a significant period.  Some new programs require us to 
devote significant capital and personnel resources to new technologies and competencies.  We may not meet customer 
expectations, which could damage our relationships with the affected customers and impact our ability to deliver 
conforming product on a timely basis.  Further, the success of new programs may depend heavily on factors such as 
product reliability, market acceptance, regulatory approvals and/or economic conditions.  The failure of a new program 
to meet expectations on these factors, or our inability to effectively execute on a new program’s requirements, could 
result in lost financial opportunities and adversely affect our results of operations. 

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, or other failures to manage our 
working capital, could adversely affect our operating results, including our return on invested capital. 

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 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.  

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 expect to open a new 

manufacturing facility in Malaysia (Penang) during the first quarter of fiscal 2012 and anticipate completing a new 
manufacturing facility in China (Xiamen) in the second half of fiscal 2012.  We have also announced our intention to 
construct a facility in Romania (Oradea) to replace a leased facility and further expand employment in Germany 
(Darmstadt).  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: 

•

•
•

•

•

•
•

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 
a reduction of our return on invested capital, including as a result of excess inventory or excess capacity at 
new facilities 
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, or other factors affecting particular sites, 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-

10

 
 
 
 
 
 
 
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, in early fiscal 2009 we ceased 
operations at our former Ayer, Massachusetts facility and reduced headcount in Juarez, Mexico and other North 
American facilities, even though we continued to expand 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. 

Changes in tax laws, and potential tax disputes, could affect our results. 

The Company has been granted tax holidays for its Malaysian and Xiamen, China subsidiaries.  These tax 

holidays expire in 2024 and 2013, respectively, and are subject to certain conditions with which the Company expects 
to comply and would risk adverse tax consequences if we do not.  The Malaysian Investment Development Authority 
granted approval to extend our tax holiday in Malaysia for a period of five years through December 31, 2024, subject to 
certain conditions.  Mexico adopted tax reform legislation that took effect on January 1, 2010, and provides for a 
temporary increase in its income tax and value added tax rates from 28% to 30% and 15% to 16%, respectively, along 
with certain other changes.  While we continue to analyze the impact of this legislation, we do not currently believe it 
will have a material impact on our effective income tax rate in future periods.  Given the scope of our international 
operations and our international tax arrangements, proposed changes to the manner in which U.S. based multinational 
companies are taxed in the U.S. could have a material impact on our operating results and competitiveness.   

We may experience negative or unforeseen tax consequences. 

The Company reviews the probability of the realization of our net deferred tax assets each period based on 
forecasts of taxable income in both the U.S. and foreign jurisdictions.  This review uses historical results, projected 
future operating results based upon approved business plans, eligible carryforward periods, tax planning opportunities 
and other relevant considerations.  Adverse changes in the profitability and financial outlook in the U.S. or foreign 
jurisdictions may require the creation of a valuation allowance to reduce our net deferred tax assets.  Such changes 
could result in material non-cash expenses in the period in which the changes are made.

We and our customers are subject to increasingly extensive government regulations and third party certification 
requirements.

We are subject to extensive government 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, and our 
customers', business, including our labor, employment, workplace safety, environmental and import/export practices, as 
well as many other facets of our operations.  In addition, as a result of customer requirements and the need to enhance 
our competitive position, we seek to obtain and maintain various certifications from third parties relating to our quality 
systems and standards.  The regulatory climate in the U.S. and other countries has become increasingly complex and 
regulatory activity has increased in recent periods, which can affect both our operations as well as the opportunities in 
the markets we serve due to the effects on our customers and their end users.  The regulatory climate can itself affect 
the demand for our services, and our failure to comply with regulations and certifications could seriously affect our 
operations, customer relationships, reputation and profitability.   

Our medical sector business is subject to substantial government regulation, primarily from the federal Food 

and Drug Administration (“FDA”) and similar regulatory bodies in other countries.  We must comply with statutes and 
regulations covering the design, development, testing, manufacturing and labeling of medical devices and the reporting 
of certain information regarding their safety.  Failure to comply with these 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.  
In addition, government reimbursement rates and other regulations, as well as the financial health of health care 
providers, and pending changes in how health care in the U.S. is structured and how medical devices are taxed, could 
affect the willingness and ability of end customers to purchase the products of our customers in the medical sector.  

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, 
Department of State, Federal Aviation Authority, and other governmental agencies in the U.S. as well as in other 

11

 
 
 
 
 
countries.  Failure to comply with related requirements and regulations, including the International Traffic in Arms 
Regulation, 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 governmental 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, including the Dodd-Frank Wall Street Reform and Consumer Protection Act, affecting, among 
other areas, 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.

Governments worldwide are becoming increasingly aggressive in enforcing and adopting anti-corruption laws.  

The U.S. Foreign Corrupt Practices Act, the U.K. Anti-Bribery Act, and the China Anti-Unfair Competition Law, 
among others, apply to us and our operations.  These requirements result in compliance costs, and the failure to comply 
with these requirements could result in substantial further costs to us as well as affect our reputation.   

The growth and changing requirements of our business are imposing a heightened level of activity involving 

import and export compliance requirements on us.  We were notified in April 2009 by U.S. Customs and Border 
Protection (“CBP”) of its intention to conduct a customary Focused Assessment of our import activities during fiscal 
2008 and of our processes and procedures to comply with U.S. Customs laws and regulations.  During September 2010 
the Company reported errors relating to import trade activity from July 2004 to the date of Plexus’ report.  CBP has 
indicated that on-site fieldwork for the audit was completed as of June 2011 and the Company is currently awaiting 
final determination of CBP duties and fees.  Plexus has agreed that it will implement improved processes and 
procedures and review these corrective measures with CBP.  We recorded an accrual in other current accrued liabilities 
in the first quarter of fiscal 2010 when the amount became estimable and probable, which was not material to the 
financial statements.  At this time, we do not believe that any deficiencies in processes or controls or unanticipated 
costs, unpaid duties or penalties associated with this matter will have a material adverse effect on Plexus or the 
Company’s consolidated financial position, results of operations or cash flows. 

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, legal requirements, and 

certification requirements, including many of the industry-specific regulations discussed above.  Our customers' failure 
to comply could affect their businesses, which in turn would affect our sales to them.  In addition, if our customers are 
required by regulation or other requirements to make changes in their product lines, these changes could significantly 
disrupt particular programs 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, engineering and other services are characterized by rapidly changing 

technology and evolving process developments.  Our internal 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, and attract additional such personnel 

•
• maintain and enhance our technological capabilities 
•
•
•
•

choose and maintain appropriate technological and service capabilities 
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 
requirements may render our equipment, inventory or processes obsolete or noncompetitive.  In addition, we may have 

12

 
 
 
 
 
 
 
 
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. 

An inability to successfully manage the procurement, development, implementation, or execution of information 
systems, or to adequately maintain these systems and their security, may adversely affect our business. 

As a global company with a complex business model, we heavily depend on our information systems to 

support our customers’ requirements and to successfully manage our business.  Any inability to successfully manage 
the procurement, development, implementation, execution or maintenance of our information systems, including 
matters related to system security, reliability, performance and  access, as well as any inability of these systems to fulfill 
their intended purpose within our business, could have an adverse effect on our business. In addition, our failure to 
maintain adequate data security for both our and our customers’ financial, product and other information, could 
substantially affect our business, compliance with regulations and reputation in the industry.  

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

The management of labor and production capacity in connection with the establishment of new or recent 
programs and customer relationships, such as our arrangements with The Coca-Cola Company, 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 programs, which lack a track record of 
order volume and timing, 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 programs or 
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 these transfers on a regular basis to address factors such as meeting customer needs, seeking 
long-term efficiencies or responding to market conditions, as well as due to facility openings and closures.   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 liability 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.  While we seek to insure 
against many of these risks, insurance coverage may be either inadequate or unavailable, either in general or for 
particular types of products.  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 

13

 
 
 
 
 
 
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.   Similarly, claims affecting our suppliers 
could cause those suppliers to discontinue selling materials and components upon which we rely. 

Our products are for end markets that require technologically advanced products with relatively short life-
cycles.

Factors affecting the technology-dependent end markets that we serve, in particular short product life-cycles, 

could seriously affect our customers and, as a result, Plexus.  These factors include: 

•

•

•

the inability of our customers to adapt to rapidly changing technology and evolving industry standards that 
result in short product life-cycles 
the inability of our customers to develop and market their products, some of which are new and untested 
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 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.   

Some of our competitors have substantially greater managerial, manufacturing, engineering, technical, 

financial, systems, sales and marketing resources than ourselves.  These competitors may: 

•
•
•
•
•
•

respond more quickly to new or emerging technologies  
have greater name recognition, critical mass and geographic and market presence 
be better able to take advantage of acquisition opportunities  
adapt more quickly to changes in customer requirements 
devote greater resources to the development, promotion and sale of their services and 
be better positioned to compete on price for their services. 

We may operate at a cost disadvantage compared to other EMS providers that have lower internal cost 
structures or 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 significant price reductions, reduced sales and margins, or loss of market share. 

We depend on our workforce, including certain key personnel, and the loss of key personnel or other personnel 
disruptions 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, develop 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 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.   

14

 
 
 
 
 
 
 
 
We also depend on good relationships with our workforce generally.  Any disruption in our relationships with 

our personnel, including as a result of potential union organizing activities, work actions or other labor issues, could 
substantially affect our operations and results.  

In addition, when we expand operations in either existing areas or new locations, we need to retain the services 

of sufficient qualified personnel to conduct those operations.  If we fail to retain and maintain sufficient qualified 
personnel, the operations at those locations, and consequently our financial results, could be adversely affected.  In new 
or existing facilities we may be subject to local labor practices or union activities, differing employment laws and 
regulations in various countries, and other issues affecting our workforce, all of which could affect operations at 
particular locations, which also could have adverse effects on our operational results.   

Natural disasters and other events outside our control, and the ineffective management of such events, may harm 
our business.  

Some of our facilities are located in areas that may be impacted by natural disasters, including hurricanes, 

earthquakes, water shortages, tsunamis and floods.  All facilities are subject to other natural or man-made disasters such 
as those related to global climate change, fires, acts of terrorism, breaches of security and failures of utilities.  If such an
event was to occur, our business could be harmed due to the event itself or due to our inability to effectively manage the 
effects of the particular event; potential harms include the loss of business continuity, the loss of business data and 
damage to infrastructure.   

In addition, some of our facilities possess certifications necessary to work on specialized products that our 

other locations lack.  If work is disrupted at one of these facilities, it may be impractical or we may be unable to transfer 
such specialized work to another facility without significant costs and delays.  Thus, any disruption in operations at a 
facility possessing specialized certifications could adversely affect our ability to provide products and services to our 
customers, and thus negatively affect our relationships and financial results. 

We have increased our borrowings, and we may fail to secure or maintain necessary financing. 

Under our credit agreement (the “Credit Facility”) and Note Purchase Agreement , over the past several years 

we have borrowed $325 million in term loans and notes, of which $273 million was outstanding at October 1, 2011, 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.  The Credit Facility may be increased by an additional $100 
million to a total of $200 million if we have not previously terminated all or any portion of the Credit Facility, there is 
no event of default existing under the Credit Facility and both we and the administrative agent consent to the increase.  
However, we cannot be certain that the credit facilities will provide all of the financing capacity that we will need in the 
future or that we will be able to change the credit facilities or revise covenants, if necessary or appropriate in the future, 
to accommodate changes or developments in our business and operations.  In addition, as a consequence of the turmoil 
in the global financial markets and banking systems, it is possible that counterparties to our financial agreements, 
including our credit agreement and our interest rate swap agreements, may not be willing or able to meet their 
obligations. 

Our future success may depend on our ability to obtain additional financing and capital to support possible 

future growth and future initiatives.  For example, in fiscal 2011 we issued $175 million in principal amount of 5.20% 
senior notes, due in 2018, to support our share repurchase program.  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. 

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: 

15

 
 
 
 
 
 
 
Operating risks, such as: 

•
•
•
•
•

•

the inability to integrate successfully our acquired operations’ businesses, systems 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: 

•
•
•

•
•
•

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. 

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 

We were notified in April 2009 by U.S. Customs and Border Protection (“CBP”) of its intention to conduct a 

customary Focused Assessment of our import activities during fiscal 2008 and of our processes and procedures to 
comply with U.S. Customs laws and regulations.  During September 2010 the Company reported errors relating to 
import trade activity from July 2004 to the date of Plexus’ report.  CBP has indicated that on-site fieldwork for the audit 
was completed as of June 2011 and the Company is currently awaiting final determination of CBP duties and fees.  
Plexus has agreed that it will implement improved processes and procedures and review these corrective measures with 
CBP.    We recorded an accrual in other current accrued liabilities in the first quarter of fiscal 2010 when the amount 
became estimable and probable, which was not material to the financial statements.  At this time, we do not believe that 
any deficiencies in processes or controls or unanticipated costs, unpaid duties or penalties associated with this matter 
will have a material adverse effect on Plexus or the Company’s consolidated financial position, results of operations or 
cash flows. 

The Company is party to certain other lawsuits in the ordinary course of business.  Management does not 

believe that these proceedings, individually or in the aggregate, will have a material adverse effect on the Company's 
consolidated financial position, results of operations or cash flows.

Shareholders of Record; Dividends 

As of November 11, 2011, there were approximately 630 shareholders of record.  We have not paid any cash 

dividends.  We currently anticipate that the majority of earnings in the foreseeable future will be retained to finance the 
development of our business.  However, the Company evaluates from time to time potential uses of excess cash, which 
in the future may include share repurchases, a special dividend or recurring dividends.  See also Part II, Item 7, 
“Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital

In fiscal 2009, we recorded goodwill impairment charges related to our United Kingdom operations of $5.7 
million.  In addition, we recorded pre-tax restructuring costs totaling $2.8 million which related primarily to 
the reduction of workforce in the United States and Mexico as well as fixed assets written down related to the 
closure of our Ayer, Massachusetts (“Ayer”) facility.  A favorable tax adjustment of approximately $1.4 
million, primarily related to the conclusion of federal and state audits, was also recorded. 

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

In fiscal 2007, we recorded pre-tax restructuring and asset 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”). 

We have not paid cash dividends in the past and do not currently anticipate paying them in the future.  
However, the Company evaluates from time to time potential uses of excess cash, which in the future may include share 
repurchases, a special dividend or recurring dividends.

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 deliver optimized Product Realization solutions through a unique 
Product Realization Value Stream services model.  This customer focused services model seamlessly integrates 
innovative product conceptualization, design, commercialization, manufacturing, fulfillment and sustaining services to 
deliver comprehensive end-to-end solutions for customers in the Americas, European and Asia-Pacific regions.  
Customer service is provided to over 130 branded product companies in the Wireline/Networking, Wireless 
Infrastructure, Medical, Industrial/Commercial and Defense/Security/Aerospace market sectors.   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 
verification; 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.   

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. 

In response to the evolving markets and to better reflect our customers’ end markets, we have decided to 

combine our Wireline/Networking and Wireless Infrastructure market sectors and rename them as our 
Networking/Communications market sector, beginning with our fiscal 2012 reporting. 

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

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

EXECUTIVE SUMMARY 

Fiscal 2011.  Net sales for fiscal 2011 increased by $217.8 million, or 10.8 percent, from fiscal year 2010 to 

$2,231.2 million.  Net sales increased in all of our market sectors during fiscal 2011, except for a decrease in the 
wireless infrastructure sector.   The overall higher net sales were from both new and existing customers, such as the 
ramp of production for our newer industrial commercial sector customer, as well as an increase in net sales to Juniper 
Networks, Inc. (“Juniper”), our largest customer, as a result of improved end-market demand for the mix of Juniper 
products we produce as well as new product launches.  We also experienced strong demand from a medical customer 
and a defense/security/aerospace customer during the year as a result of increased end market demand for the products 
they produce.  These increases were partially offset by decreased net sales to two significant customers, one in the 
wireline/networking sector and one in the wireless infrastructure sector, related to previously announced 
disengagements as a result of acquisitions, and decreased sales from one additional wireless infrastructure customer as a 
result of a drop in end-market demand for the mix of its products that we produce.     

Gross margin was 9.6 percent for fiscal 2011, which compared unfavorably to 10.3 percent for fiscal 2010.  

Gross margins in fiscal 2011 were lower as a result changes in our customer mix, higher fixed expenses related to 
higher headcount to support the revenue growth and increased depreciation expense.  The prior year also included 
proceeds from a litigation settlement (see Note 12).   

Selling and administrative expenses were $113.6 million for fiscal 2011, an increase of $6.3 million, or 5.9 

percent, from the $107.3 million for fiscal 2010.  The majority of the increase was due to higher employee 
compensation and relocation expense as a result of higher headcount to support revenue growth as well as higher stock 
based compensation expense.  This was partially offset by lower variable incentive compensation in fiscal 2011 as 

23

compared to fiscal 2010.  Selling and administrative expenses were 5.1 percent of sales for fiscal 2011, as compared to 
5.3 percent in fiscal 2010.      

Other expense for fiscal 2011 decreased slightly from 2010, driven primarily by the favorable fluctuation in 

foreign currency translation, partially offset by increased interest expense.      

Net income for fiscal 2011 was $89.3 million and diluted earnings per share were $2.30, which compared to 
net income of $89.5 million, or $2.19 per diluted share, for fiscal 2010.  Net income decreased slightly from the prior 
year period due to changes in customer mix and higher fixed and selling and administrative expenses, partially offset by 
increased sales.  Diluted earnings per share increased from the prior year period due to lower average shares 
outstanding related to our share repurchase program.  The effective tax rate in the current year period was 
approximately 3 percent, which compares unfavorably to the 1 percent tax rate in the prior year period primarily due to 
the mix of the Company’s fiscal 2011 pre-tax income.

Fiscal 2010.  Net sales for fiscal 2010 increased by $396.8 million, or 24.5 percent, from fiscal year 2009 to 

$2,013.4 million.  Net sales increased in all of our market sectors during fiscal 2010, except for a slight decrease in the 
defense/security/aerospace sector.   The overall higher net sales were driven primarily by stronger end-market 
conditions, as well as the ramp of production for new customer programs in the wireless infrastructure, 
wireline/networking, industrial/commercial, and medical sectors.  These increases were partially offset by decreased net 
sales from two defense/security/aerospace sector customers, as well as decreased net sales to Juniper.  Net sales to 
Juniper declined slightly as a result of decreased end-market demand for the mix of Juniper products produced by us.   

Gross margin was 10.3 percent for fiscal 2010, which compared favorably to 9.6 percent for fiscal 2009.  

Gross margins in fiscal 2010 were higher due to the increased net sales, changes in customer mix and proceeds from a 
litigation settlement (see Note 12), partially offset by increases in variable incentive compensation expense due to 
strong financial performance as well as fixed expenses as a result of higher headcount.   

Selling and administrative expenses were $107.3 million for fiscal 2010, an increase of $14.2 million, or 15.3 

percent, from the $93.1 million for fiscal 2009.  Sixty percent of the increase was due to higher variable incentive 
compensation in fiscal 2010 as compared to fiscal 2009.  The remainder of the increase was driven primarily by 
increased employee compensation expense as a result of higher headcount to support revenue growth.    

For fiscal 2010, the Company did not incur any restructuring or impairment charges as compared to charges of 

$8.6 million in fiscal 2009.     

Net income for fiscal 2010 was $89.5 million and diluted earnings per share were $2.19, which compared 

favorably to net income of $46.3 million, or $1.17 per diluted share, for fiscal 2009.  Net income increased from fiscal 
2009 due to overall increased sales and higher gross margins and the absence of restructuring charges, offset by 
increased fixed expenses and selling and administrative expenses.  The effective tax rate in fiscal 2010 was 1 percent, 
which compares unfavorably to the 2 percent tax benefit in fiscal 2009.  The increase in effective tax rate from fiscal 
2009 was primarily due to the mix of the Company’s fiscal 2010 pre-tax income and the absence in 2010 of a net $1.4 
million tax benefit resulting from a discrete event that occurred in fiscal 2009.  

Other. The effective income tax rates (benefits) for fiscal 2011, 2010 and 2009 were 3 percent, 1 percent and 

(2) percent, respectively.  The increase in effective tax rate from fiscal 2009 to fiscal 2010 was primarily due to the mix 
of the Company’s fiscal 2010 pre-tax income and the absence in 2010 of a net $1.4 million tax benefit resulting from a 
discrete event that occurred in fiscal 2009.   The change in our effective tax rate from fiscal 2010 to fiscal 2011 is 
primarily due to changes in the mix of income in the tax jurisdictions in which we operate.        

ROIC.  One of our metrics for measuring financial performance is after-tax ROIC.  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 15.6 percent, 19.5 percent and 13.2 percent for fiscal 2011, 2010 and 2009, respectively.  See 
the table below for our calculation of ROIC (dollars in millions):

ROIC is a non-GAAP financial measure which should be considered in addition to, not as a substitute for, 

measures of the Company’s financial performance prepared in accordance with United States generally accepted 
accounting principles (“GAAP”).  Non-GAAP financial measures, including ROIC, are used for internal management 
assessments because such measures provide additional insight into ongoing financial performance. In particular, we 
provide ROIC because we believe it offers insight into the metrics that are driving management decisions as well as 
management’s performance under the tests which it sets for itself. 

For a reconciliation of ROIC to our financial statements that were prepared using GAAP, see Exhibit 99.1 to 

this annual report on Form 10-K, which exhibit is incorporated herein by reference.

Net sales for fiscal 2011 increased $217.8 million, or 10.8 percent, as compared to fiscal 2010.  The net sales 
increase resulted from higher net sales in all of our market sectors, except for a decrease in the wireless infrastructure 
sector.  The net sales increase primarily related to the ramp of production for a newer industrial commercial sector 
customer.  Net sales to Juniper increased as a result of improved end-market demand for the mix of Juniper products we 
produce as well as new product launches.  Overall, we had net sales increases spread across new and existing customers 
in both the industrial commercial and medical sectors during fiscal 2011, which were partially offset by the two 
previously announced disengagements as a result of acquisitions (with one each in the wireline/networking and the 
wireless infrastructure market sectors), as well as decreased sales from one additional wireless infrastructure customer 
as a result of a drop in end-market demand for the mix of its products that we produce.    

Net sales for fiscal 2010 increased $396.8 million, or 24.5 percent, as compared to fiscal 2009.  The net sales 

increase resulted from higher net sales in all of our market sectors, except for the defense/security/aerospace sector.  
The overall higher net sales were driven primarily by strong end-market conditions, as well as the addition of new 
customers in the wireless infrastructure, wireline/networking, industrial/commercial and medical sectors.  These net 
sales increases were offset in part by decreased net sales to two defense/security/aerospace customers, as well as lower 
net sales to Juniper as a result of a decline in end-market demand for the mix of Juniper products produced by us.

Net sales to our largest 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 with our top 10 customers remained at or above 53 
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, including 
global economic conditions.  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 will become increasingly dependent upon the economic and business 
conditions affecting that sector.   

In the current economic environment, we are seeing increased merger and acquisition activity that has 

impacted our customers.  Specifically, we previously announced that two of our customers were acquired in the first 
quarter of fiscal 2010.  The customer in the Wireline/Networking sector began to reduce orders to us at the end of fiscal 
2010 and substantially disengaged in fiscal 2011.  The customer in the Wireless Infrastructure sector began 
disengagement in fiscal 2011 and also substantially disengaged in fiscal 2011.

For fiscal 2011, gross profit and gross margin were impacted by the following factors: 

•

•

•
•

increased net sales in all of our market sectors except wireless infrastructure, driven by demand from new and 
existing customers across the majority of our market sectors, partially offset by unfavorable changes in 
customer mix, which together accounted for approximately $32.4 million of the net increase in gross profit 
partially offset by an increase in fixed manufacturing costs due to increased headcount expenses to support 
revenue growth of approximately $15.5 million.  Fixed costs also grew as a percentage of sales as a result of 
expansion in our APAC and EMEA regions as they ramp to capacity, as well as the underutilization of two 
AMER facilities, due to the disengagement of a significant customer and the slower ramp of a significant 
customer 
increased depreciation expense of $5.5 million due to the expansions mentioned above, and 
the effect of the non-recurrence of a $3.2 million benefit in the first quarter of fiscal  2010 from a litigation 
settlement. 

For fiscal 2010, gross profit and gross margin were impacted by the following factors: 

•

increased net sales in all of our reportable segments, driven by strong end-market conditions, as well as the 
addition of new customers in the wireless infrastructure, wireline/networking, industrial/commercial and 
medical sectors, as well as favorable changes in customer mix, which together accounted for approximately 
$38.8 million of the increase in gross profit

•

•

increased capacity utilization from the higher revenue levels 
proceeds of $3.2 million received from a litigation settlement, which was recorded as a reduction to cost of 
sales, and  
partially offset by increased variable compensation expense of approximately $6.6 million as a result of 
improved financial performance and fixed expenses, primarily in the AMER and APAC reportable segments, 
due to increased headcount to support the revenue growth.  

Design work performed by the Company is not the proprietary property of Plexus and substantially all costs 

incurred with this work are 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.

For fiscal 2011, the increase in S&A expenses was due to increased employee compensation and relocation 

expense of approximately $8.1 million as a result of higher headcount to support revenue growth, as well as higher 
stock-based compensation expense of approximately $1.1 million.  This was partially offset by lower variable incentive 
compensation in fiscal 2011 as compared to fiscal 2010 of approximately $4.1 million. S&A expenses as a percentage 
of net sales decreased during fiscal 2011 as a result of net sales expanding more quickly than these cost increases.  

For fiscal 2010, sixty percent of the increase in S&A expenses was due to higher variable incentive 
compensation expense as a result of strong financial performance.  The remainder of the increase was driven primarily 
by an increase in headcount to support our revenue growth.  S&A expenses as a percentage of net sales decreased 
during fiscal 2010 as a result of net sales expanding more quickly than these cost increases.  

Restructuring and asset impairment charges.  For both fiscal 2011 and fiscal 2010, we did not incur any 
restructuring or asset impairment charges.   Our restructuring and asset impairment costs for fiscal 2009 were as follows 
(dollars in millions):

The restructuring and asset impairment charges for fiscal 2009 were associated with various reportable 
segments. Management excludes such charges when analyzing the performance of the reportable segments. See Note 13

Other income (expense) for fiscal 2011 decreased $0.1 million, to $9.1 million of expense from $9.2 million of 

expense in fiscal 2010.  This change was driven by the favorable fluctuation in foreign currency translation and 
transaction adjustments of $2.4 million, partially offset by increased interest expense of $2.1 million, primarily related 
to our private placement debt, which we entered into during the third quarter of fiscal 2011 as discussed in “Liquidity 
and Capital Resources” below.      

Other income (expense) for fiscal 2010 increased $1.5 million, to $9.2 million of expense from $7.7 million of 

expense in fiscal 2009.  This change was driven by the unfavorable fluctuation in foreign currency translation and 
transaction adjustments of $2.1 million and reduced interest income of $0.9 million due to lower effective interest rates, 
partially offset by decreased interest expense of $1.3 million, primarily related to servicing the $150 million term loan 
drawn in April 2008.

(2.0)% 

The change in our effective tax rate from fiscal 2009 to fiscal 2011 is primarily due to change in mix in the tax 

jurisdictions in which we operate.     

As a result of using the with-and-without method under the requirements for accounting for stock-based 
compensation, the Company recorded a valuation allowance for federal and state taxes 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.  As of the end of fiscal 2010 there was a 
valuation allowance of $1.0 million for federal and state taxes against the amount of net operating loss and credit 
carryforwards related to tax deductions in excess of compensation expense for stock options.  During fiscal 2011 the 
Company recorded an additional valuation allowance $1.3 million.  As a result, we had a remaining valuation allowance 
of approximately $2.3 million related to tax deductions associated with stock-based compensation as of October 1, 
2011.   

During the preparation of the Company’s fiscal 2011 consolidated financial statements, the Company 
performed an analysis of all available evidence, both positive and negative, regarding the need for a valuation 
allowance against our deferred tax assets, consistent with the provisions of ASC Topic 740, “Income Taxes.”  The 
Company’s U.S. operations generated losses during the fiscal 2009, 2010 and 2011 years.  While we believe these 
losses could be a significant factor in establishing such an allowance, we believe that based on the weight of all the 
evidence, both positive and negative, it is more likely than not that the Company will be able to utilize its U.S. net 
deferred tax assets of approximately $21.7 million.  See Note 6 – Income Taxes for further details. 

In addition, there was a remaining valuation allowance of $1.6 million as of October 2, 2010, 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.  There was no change in the valuation allowance during fiscal 2011.   If the U.S. 
operations continue to generate losses, there may be a need to provide a valuation allowance on our net U.S. deferred 
tax assets, which totaled $21.7 million as of October 1, 2011.

During fiscal 2011 the Company added a valuation allowance of $0.3 million and $0.9 million in the United 
Kingdom and Romania, respectively, to offset the increase in net deferred tax assets in those jurisdictions which more 
likely than not will not be realized. 

We currently expect the annual effective tax rate for fiscal 2012 to be approximately 8 to 10 percent.  The rate 

increase is due mainly to the increase in projected income in the United States and lower projected income in low tax 
Malaysia and China jurisdictions.   

The Company has been granted tax holidays for its Malaysian and Xiamen, China subsidiaries.  These tax 

holidays expire in 2024 and 2013, respectively, and are subject to certain conditions with which the Company expects 
to comply.  In fiscal 2011, 2010 and 2009, these subsidiaries generated income, which resulted in tax reductions of 
approximately $21.7 million ($0.57 per basic share), $23.0 million ($0.58 per basic share) and $15.2 million ($0.38 per 
basic share), respectively. 

Net Income.  As a result of the above factors, our net income decreased by $0.3 million, or (0.3) percent, in 
fiscal 2011 as compared to fiscal 2010.  Diluted earnings per share increased by 5.0 percent due to the effects of our 
fiscal 2011 stock repurchases.  Net income increased by $43.2 million, or 93.3 percent, in fiscal 2010 compared to fiscal 
2009; diluted earnings per share increased 87.2 percent.      

REPORTABLE SEGMENTS 

In the first quarter of fiscal 2011, we completed our migration to a regional reporting structure, and as a result, 

modified our reportable segments.  See Note 1 – Description of Business and Significant Accounting Policies for 
further information.

Americas (AMER):    

Net sales for fiscal 2011 increased $60.2 million, or 4.8 percent, from fiscal 2010, which reflected the ramp of 
production for our newer industrial commercial sector customer.  Net sales to Juniper also increased as a result 
of improved end-market demand for the mix of Juniper products we produce in the region as well as new 
product launches.  These increases were offset by reduced net sales to two significant wireless infrastructure 
customers, one as a result of a previously announced disengagement and the other as a result of a drop in end-
market demand for the mix of products we produce for that customer.  Operating income for fiscal 2011 
decreased $5.7 million from fiscal 2010 due to the prior year period benefitting from a $3.2 million litigation 
settlement, as well as changes in customer mix in the current year.    

Net sales for fiscal 2010 increased $160.4 million, or 14.8 percent, from fiscal 2009.  This increase reflected 
higher end-market demand from numerous existing customers in each of our market sectors and the ramp of

production for new customers in the wireline/networking, wireless infrastructure, industrial/commercial and 
medical sectors.  These increases were partially offset by reduced net sales to our largest customer, Juniper, 
due to the transfer of manufacturing of some products to our APAC reportable segment, as well as decreased 
end-market demand for the mix of Juniper products produced by us.  Operating income for fiscal 2010 
increased $13.2 million from fiscal 2009 primarily as a result of higher revenues from the customers noted 
above, improved operating efficiencies resulting from higher production levels and proceeds received from a 
litigation settlement.  

Asia-Pacific (APAC):   

Net sales for fiscal 2011 increased $137.7 million, or 14.9 percent, over fiscal 2010.  This growth reflected 
higher net sales to multiple customers across our market sectors as well as increased demand from a new 
customer in the industrial/commercial sector.  These increases were partially offset by decreases in net sales 
from the previously announced disengagement of one customer in the wireline/networking sector as well as a 
drop in end-market demand for the mix of products we produce for a wireless infrastructure customer.  
Operating income improved $3.3 million in fiscal 2011 as compared to fiscal 2010, primarily as a result of the 
net sales growth, partially offset by changes in customer mix and higher fixed expenses.   

Net sales for fiscal 2010 increased $337.3 million, or 57.4 percent, over fiscal 2009.  This growth reflected 
higher net sales to multiple customers across our market sectors, increased demand from a new customer in the 
industrial/commercial sector and the transfer of the manufacturing of some Juniper products to the APAC 
reportable segment from the AMER reportable segment, partially offset by the decrease in demand from 
Juniper described above.  Operating income improved $51.1 million in fiscal 2010 as compared to fiscal 2009, 
primarily as a result of the net sales growth and operating efficiencies resulting from higher production levels.   

Europe, Middle East and Africa (EMEA):

Net sales for fiscal 2011 increased $19.7 million, or 27.2 percent, from fiscal 2010.  The change in net sales 
was driven by higher demand from two existing customer programs as well as the ramp of production for two 
new customers.  Operating results were lower in the current year as compared to the prior year due to increased 
operating costs from our Romania facility and our new engineering facility in Darmstadt, Germany. 

Net sales for fiscal 2010 increased $16.9 million, or 30.4 percent, from fiscal 2009.  The change in net sales 
can be attributed to higher demand from the ramp of production for two existing customer programs in the 
industrial/commercial sector.  Operating results were lower in the current year as compared to the prior year 
due to operating costs from our new Romania facility.   

For our significant customers, we generally manufacture products in more than one location.  For example, 
sales to Juniper occur in AMER and APAC.  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. 

LIQUIDITY AND CAPITAL RESOURCES 

Cash flows provided by operating activities were $161.7 million for fiscal 2011, compared to cash flows 
provided by operating activities of $2.0 million and $170.3 million for fiscal 2010 and 2009, respectively.  During fiscal 
2011, the increase in cash flows provided by operating activities was primarily the result of improvements in working 
capital.         

Inventory decreased by $36.6 million during fiscal 2011 as compared to fiscal 2010.  Inventory turns increased 

to 4.3 turns in fiscal 2011 from 4.1 turns in fiscal 2010.  Days in inventory changed favorably as of October 1, 2011 to 
85 days as compared to 90 days at October 2, 2010.  The decrease in inventory, both in dollars and days of cash cycle, 
was the result of our efforts to actively manage our inventory levels down with the assistance of our customers, while 
continuing to meet our customers’ needs for flexibility and agility.  As part of our continued efforts to mitigate 
inventory risk, we have collected approximately $29.8 million in cash deposits from our customers, which are classified 
as customer deposits on the Consolidated Balance Sheets, and have also continued to work with customers that have 
excess inventory issues in accordance with contractual obligations.   

The overall decrease in accounts receivable of $27.2 million during fiscal 2011 as compared to fiscal 2010 was 

mainly due to two customers, one in each of the industrial/commercial and the wireline/networking sectors, prepaying 

30

   
 
their respective accounts in fiscal 2011.  Our annualized days sales outstanding in accounts receivable for fiscal 2011 
decreased favorably from 51 days in fiscal 2010 to 48 days in fiscal 2011. 

Cash flows used in investing activities totaled $71.9 million for fiscal 2011.  The primary investments included 

$74.1 million for purchases of property, plant and equipment, mainly in our APAC region, partially offset by proceeds 
from the sale of property, plant, and equipment.  Investments were for new equipment to support customer demand in 
all of our regions as well as investments in new facilities in Penang, Malaysia and Xiamen, China to increase capacity.  
We expect our fourth Penang, Malaysia facility to be operational in our first quarter of fiscal 2012 and our second 
Xiamen, China facility to be operational in the second half of fiscal 2012.  See Note 13 in Notes to Consolidated 
Financial Statements for further information regarding our capital expenditures by reportable segment.  Fiscal 2011 
purchases of property, plant and equipment included $48.1 million, $15.7 million, and $10.3 million related to our 
APAC, AMER, and EMEA reportable segments, respectively.      

We utilized available cash and operating cash flows as the principal sources for funding our operating 
requirements during fiscal 2011.  We currently estimate capital expenditures for fiscal 2012 to be approximately $90-95 
million.  A significant portion of the fiscal 2012 capital expenditures is anticipated to be used for the completion of the 
two facilities mentioned above (Penang, Malaysia and Xiamen, China).  We also anticipate announcing, during the first 
half of fiscal 2012, the construction of a larger facility in Oradea, Romania to replace leased buildings that served as our 
start-up solution in lower-cost Europe. 

Cash flows used in financing activities totaled $37.0 million for fiscal 2011, primarily due to purchases of 

common stock related to our stock repurchase program as well as payments on our term note and capital leases, offset 
by proceeds from our private placement debt issuance and proceeds from the exercise of stock options.   

On February 16, 2011 the Company’s Board of Directors approved a share repurchase program that authorized 

the Company to repurchase up to $200 million of common stock.  On August 15, 2011, the Company completed its 
share repurchase program with a total of 6.3 million shares purchased at a volume-weighted average of $31.69 per 
share.  The Company did not repurchase any shares in fiscal 2010. 

To support our new share repurchase program, we entered into a Note Purchase Agreement (the “Agreement”) 
for $175 million in principal amount of 5.20% Senior Notes, due June 15, 2018 (the “Notes”) during the third quarter of 
fiscal 2011.  We issued $100 million in principal amount of the Notes on April 21, 2011, and the remaining $75 million 
on June 15, 2011.  The Agreement includes operational and financial covenants which include a maximum total 
leverage ratio, a minimum interest coverage ratio and restrictions on additional indebtedness, liens and dispositions, all 
as defined in the Agreement.  We are currently in compliance with all such covenants.  Origination fees and expenses 
associated with the private placement totaled approximately $0.9 million and have been deferred.  These origination 
fees and expenses are being amortized over the seven-year term of the Notes.  Semi-annual interest payments began on 
June 15, 2011 and end on June 15, 2018 with full repayment of the total principal of the Notes. 

During the second quarter of fiscal 2011, we entered into two separate treasury rate lock hedge contracts to 

hedge the variability of the fixed interest rate on the then forecasted issuance of $175 million of fixed rate debt using a 
treasury lock transaction.  The fixed interest rates for each of these contracts are 2.77% and 2.72%, respectively, with a 
notional value of $150 million.  On April 4, 2011, we entered into a final treasury rate lock hedge transaction for the 
remaining $25 million of exposure at a rate of 2.88%.  On April 8, 2011, when the fixed interest rate for the debt 
issuance was determined, all three treasury rate lock contracts were settled and we received proceeds of $2.3 million, 
which is being amortized over the seven year term of the related debt. 

On April 4, 2008, we entered into our credit agreement (the “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 Credit Facility is 
unsecured and may be increased by an additional $100 million to a total of $200 million (the “accordion feature”).  This 
is possible if we have not previously terminated all or any portion of the 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 Credit 
Facility expires on April 4, 2013.  Borrowings under the Credit Facility may be either through term loans or revolving 
or swing loans or letter of credit obligations.  As of October 1, 2011, we had term loan borrowings of $97.5 million 
outstanding and no revolving borrowings under the Credit Facility. 

The 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 October 1, 2011, we were in compliance with all debt covenants.  If 

31

   
    
 
 
we incur an event of default, as defined in the Credit Facility (including any failure to comply with a financial 
covenant), the group of banks has the right to terminate the Credit Facility and all other obligations, and demand 
immediate repayment of all outstanding sums (principal and accrued interest).  The interest rate on the borrowing varies 
depending upon our then-current total leverage ratio; as of October 1, 2011, the Company could elect to pay interest at a 
defined base rate or the LIBOR rate plus 1.50%.  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%.  We are also required to pay an annual commitment fee on the unused credit commitment based on our leverage 
ratio; the current fee is 0.375%.  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 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 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 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) exists at the time of, or would be caused 
by, the dividend payment or the share repurchases. 

Additionally, the Company enters interest rate swaps and foreign currency derivatives to hedge against 

variable cash flows.  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.  See Note 5 – Derivatives and Fair Value Measurements for further details.

In February 2010, the Company negotiated the settlement of a capital lease in Kelso, Scotland.  The termination of 
this capital lease obligation and acquisition of the property was effected through a cash payment by Plexus of $3.9 million. 

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

short-term investments, the Credit Facility, and our leasing capabilities should be sufficient to meet our working capital 
and fixed capital requirements for the next twelve months.  $100 million of committed credit is currently available 
under the Credit Facility, with another $100 million available in an “accordion” facility, which is contingent upon 
compliance with the Credit Agreement and lender approval.  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 have not paid cash dividends in the past and do not currently anticipate paying them in the future.  
However, the Company evaluates from time to time potential uses of excess cash, which in the future may include share 
repurchases, a special dividend or recurring dividends.

As of April 4, 2008, we entered into the Credit Facility and immediately funded a term loan for $150 million.  
As of October 1, 2011, the outstanding balance was $97.5 million.  The amounts listed above include interest, 
as we intend to hold the loan to maturity.  See Note 4 in Notes to Consolidated Financial Statements for further 
information. 

As of April 21, 2011, we entered into the Note Purchase Agreement and immediately issued $100 million in 
principal amount and another $75 million in principal amount of notes on June 15, 2011.  The amounts listed 
above include interest, as we intend to hold the notes to maturity.  See Note 4 in Notes to Consolidated 
Financial Statements for further information. 

As of October 1, 2011, purchase obligations consist of purchases of inventory and equipment in the ordinary 
course of business. 

As of October 1, 2011, other long-term obligations on the balance sheet included deferred compensation 
obligations to certain of our former and current executive officers, as well as other key employees, and an asset 
retirement obligation.  We have excluded from the above table the impact of approximately $7.4 million, as of 
October 1, 2011, related to unrecognized income tax benefits.  The Company cannot make reliable estimates of 
the future cash flows by period related to this obligation. 

As of October 1, 2011, 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 
are material.   

DISCLOSURE ABOUT CRITICAL ACCOUNTING POLICIES

Our accounting policies are disclosed in Note 1 of Notes to the Consolidated Financial Statements.  During 
fiscal 2011, there were no material changes to these policies.  Our more critical accounting policies are noted below: 

Stock-Based Compensation – The Financial Accounting Standard Board (“FASB”) requires all share-based 
payments to employees, including grants of employee stock options, to be measured at fair value and expensed in the 
consolidated statements of operations over the service period (generally the vesting period) of the grant. We used the 
modified prospective application, under which compensation expense is only recognized in the consolidated statements 
of operations beginning with the first period that we adopted the FASB regulation and continuing to be expensed 
thereafter. 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 management’s assumptions, including future 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 – During the second quarter of fiscal 2009, we recorded a goodwill impairment charge of 

$5.7 million, related to the Company’s sole goodwill asset.   The impairment wrote off the entire carrying value of our 
goodwill related to our Kelso facility, which was the sole reporting unit in the EMEA reportable segment.  The 
impairment charge was driven by adverse macroeconomic conditions that contributed to an overall reduction in demand 
for the Company’s offerings from the Kelso facility.  These conditions led to an “interim triggering event”, leading 
management to perform an interim goodwill impairment test.  This test resulted in the determination that the carrying 
value of the goodwill relating to Kelso was fully impaired and therefore an impairment charge of $5.7 million was 
taken.  

Should we have goodwill and intangible assets with indefinite useful lives in the future, we would test those 

assets for impairment, at least annually, and recognize any related losses when incurred.     

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 

with durations of twelve months or less, are typically recognized as costs are incurred utilizing the proportional 
performance model.  The completed performance model is used if certain customer acceptance criteria exist.  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.  See Note 5 – Derivatives and Fair Value Measurements 
for further details.

Income Taxes – The Company accounts for income taxes in accordance with ASC Topic 740, “Income 

Taxes.”  Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences 
between financial statement carrying amounts of existing assets and liabilities and their respective tax bases and 
operating loss and tax credit carryforwards.  Deferred tax assets and liabilities are measured using enacted tax rates 
expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or 
settled.  Accordingly, the Company does not currently provide for additional U.S. and foreign income taxes which 
would become payable upon repatriation of undistributed earnings of certain foreign subsidiaries.  The Company 
maintains valuation allowances when it is more likely than not that all or a portion of a deferred tax asset will not be 
realized.  In determining whether a valuation allowance is required, the Company takes into account such factors as 
prior earnings history, expected future earnings, carryback and carryforward periods, and tax strategies that could 

34

potentially enhance the likelihood of realization of a deferred tax asset.  If the U.S. operations continue to generate 
losses, there may be a need to provide a valuation allowance on our net U.S. deferred tax assets, which totaled $21.7 
million as of October 1, 2011.

See Note 1 in Notes to Consolidated Financial Statements regarding recent accounting pronouncements. 

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 partially offsets the effects of changes in foreign currency 
exchange rates.  We typically use foreign currency contracts to hedge only those currency exposures associated with 
certain assets and liabilities denominated in non-functional currencies.  Corresponding gains and losses on the 
underlying transaction generally offset the gains and losses on these foreign currency hedges. Our international 
operations create potential foreign exchange risk.  Beginning in July 2009, we entered into forward contracts to hedge a 
portion of our foreign currency denominated transactions in our APAC reportable segment and beginning in July 2011, 
we entered into forward contracts to hedge a portion of our foreign currency denominated transactions in Mexico, as 
described in Note 5 to Notes to Consolidated Financial Statements.     

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

were as follows: 

Net Sales 
Total Costs 

Fiscal year 
2010 
5% 
13% 

2009 
4% 
11% 

2011 
6% 
14% 

The Company has evaluated the potential foreign currency exchange rate risk on transactions denominated in 

currencies other than the U.S. dollar for the periods presented above.  Based on the Company’s overall currency 
exposure, as of October 1, 2011, a 10 percent change in the value of the U.S. dollar relative to our other transactional 
currencies would not have a material effect on the Company’s financial position, results of operations, or cash flows. 

Interest Rate Risk 

We have financial instruments, including cash equivalents and short-term investments as well as debt, which 

are sensitive to changes in interest rates.  We consider the use of interest-rate swaps and treasury rate locks based on 
existing market conditions.  We have entered into interest rate swaps for $97.5 million in term loans, as described in 
Note 5 in Notes to Consolidated Financial Statements.  As is common with these types of agreements, our interest rate 
swap and treasury rate lock agreements are subject to the further risk that the counterparties to these agreements may 
fail to comply with their obligations thereunder.   

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 as of October 1, 2011, is associated with our Credit Facility under which we 

borrowed $150 million.  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 interest expense.

FINANCIAL DISCLOSURE

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) in assuring that information is 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 October 1, 
2011, based on the criteria established in “Internal Control – Integrated Framework” issued by the Committee of 
Sponsoring Organizations of the Treadway Commission (“COSO”).  Based on its assessment and those criteria, 
management of the Company has concluded that, as of October 1, 2011, 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 October 1, 2011, 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 

conclusion that our disclosure controls and procedures and our internal control over financial reporting are effective at 
the reasonable assurance level.

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 October 1, 2011 and October 2, 2010, and the 
results of their operations and their cash flows for each of the three years in the period ended October 1, 2011 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 
October 1, 2011, 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 schedule, 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. 

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.

Description of Business and Significant Accounting Policies

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

“we”) participate in the Electronic Manufacturing Services (“EMS”) industry.  We deliver optimized Product 
Realization solutions through a unique Product Realization Value Stream services model.  This customer 
focused services model seamlessly integrates innovative product conceptualization, design, 
commercialization, manufacturing, fulfillment and sustaining services to deliver comprehensive end-to-end 
solutions for customers in the Americas, European, and Asia-Pacific regions.  Customer service is provided to 
over 130 branded product companies in the Wireline/Networking, Wireless Infrastructure, Medical, 
Industrial/Commercial and Defense/Security/Aerospace market sectors.   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 verification; 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.   

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 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.  Periodically, an additional week must be added to the fiscal year to 
re-align with the Saturday closest to September 30.  Fiscal 2009 included this additional week and the fiscal 
year ended on October 3, 2009.  Therefore fiscal 2009 included 371 days.  The additional week was added to 
the first fiscal quarter, ended January 3, 2009, which included 98 days.  The accounting years for fiscal 2011 
and 2010 each included 364 days. 

In the first quarter of fiscal 2011, as previously announced, we completed our migration to a regional 

reporting structure.  This change included establishing regional targets for various financial metrics, 
delegating additional authority to the regions to manage their business, and changing our related internal 
reporting.  Given this change to regional reporting and management, as well as in the information used by 
management for assessing performance and allocating Company resources, we modified our reporting 
segments.  Prior to fiscal 2011, the Company’s reportable segments consisted of the United States, Asia, 
Europe and Mexico.  During the first quarter of fiscal 2011, we combined our United States and Mexico 
segments into the “Americas” (“AMER”) segment and renamed our Asia segment “Asia-Pacific” (“APAC”) 
and our Europe segment “Europe, Middle East and Africa” (“EMEA”) to better represent our long-range 
regional focus.  As a result, we have conformed all prior period segment presentations to be consistent with 
our current reportable segments.  See Note 13 - Reportable Segments, Geographic Information and Major 
Customers for further information.

Cash and Cash Equivalents: Cash equivalents are highly liquid investments purchased with an 

original maturity of less than three months (in thousands):

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. 

Per contractual terms, customer deposits are received by the Company to offset obsolete and excess 

inventory risks.     

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 capitalizes significant costs incurred in the 
acquisition or development of software for internal use, including the costs of the software, consultants as 
well as payroll and payroll-related costs for employees directly involved in developing internal use computer 
software once the final selection of the software is made. 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:  During fiscal 2009, the Company recorded a goodwill 

impairment charge of $5.7 million, writing off the entire carrying value of its goodwill related to its Kelso, 
Scotland (“Kelso”) facility.  The impairment charge was driven by macroeconomic conditions that 
contributed to an overall reduction in demand for the Company’s offerings from the Kelso facility.  These 
conditions led to an “interim triggering event,” leading management to perform an interim goodwill 
impairment test.  This test resulted in the determination that the carrying value of the goodwill relating to 
Kelso, the Company’s sole remaining goodwill asset, was fully impaired and therefore an impairment charge 
of $5.7 million was recorded. 

Should the Company have goodwill and intangible assets with indefinite useful lives in the future, 

the Company would test those assets for impairment at least annually, and recognize any related losses when 
incurred.  Recoverability of goodwill would be measured at the reporting unit level.  The Company would 
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 would be 
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 would be 

46 

 
 
 
 
 
 
 
 
 
 
Plexus Corp. 
Notes to Consolidated Financial Statements

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. 

Impairment of Long-Lived Assets: Long-lived assets, including property, plant and equipment and 

intangible assets with finite lives are reviewed for impairment and written down to fair value when facts and 
circumstances indicate that the carrying value of long-lived assets may not be recoverable through estimated 
future undiscounted cash flows.  If an impairment has occurred, a write-down to estimated fair value is made 
and the impairment loss is recognized as a charge against current operations.  The impairment analysis is 
based on management’s assumptions, including future 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, among others.  

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 typically recognized as program costs are incurred 
utilizing the proportional performance model.  The completed performance model is used if certain customer 
acceptance criteria exist.  Any losses are recognized when anticipated.  Net sales from engineering design and 
development services were less than five percent of total sales in fiscal 2011, 2010 and 2009. 

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.  

Income Taxes:  Deferred income taxes are provided for the difference between the financial 

statement balance of assets and liabilities and their respective tax basis.  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.  Recognition of 
deferred income tax assets is evaluated and tax reserves are recorded to address potential exposures related to 
income tax positions taken by the Company.  These reserves are based on the assumptions and past 
experiences of the Company and provide for the uncertainty surrounding the application of statutes, rules, 
regulations, and interpretations to its income tax filings.  It is possible that the actual costs or benefits relating 
to these matters may be materially more or less than the amount the Company estimated.   

Foreign Currency Translation:  We translate assets and liabilities of subsidiaries operating outside 

of the U.S. with a functional currency other than the U.S. dollar into U.S. dollars using exchange rates in 
effect at year-end.  We translate net sales, expenses and cash flows at the average monthly exchange rates 
during the respective periods.  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 income (expense).  Exchange 
gains (losses) on foreign currency transactions were $1.0 million, $(1.5) million, and $0.7 million for the 
fiscal years ended October 1, 2011, October 2, 2010, and October 3, 2009, respectively.  

Derivatives:  The Company periodically enters into derivative contracts such as foreign currency 
forwards and interest rate swaps, 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 

47 

Plexus Corp. 
Notes to Consolidated Financial Statements

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 qualifies 
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” within shareholders’ equity, 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 “Accumulated other comprehensive income” within shareholders’ equity.  Our interest rate 
swaps and forward contracts are treated as cash flow hedges and, therefore, $(0.4) million, $2.0 million and 
$(3.2) million were recorded in “Accumulated other comprehensive income” for fiscal 2011, 2010 and 2009, 
respectively.

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.  The computation of diluted 
earnings per common share reflects additional dilution from stock options and restricted stock, excluding any 
with an antidilutive effect.  

Stock-based Compensation:  The Company measures all share-based payments to employees, 

including grants of employee stock options, at fair value and expenses them in the Consolidated Statements 
of Operations over the service period (generally the vesting period) of the grant.  

Comprehensive Income:  The Company follows the established standards for reporting 

comprehensive income, which is defined as the changes in equity of an enterprise except those resulting from 
shareholder transactions.  

Accumulated other comprehensive income consists of the following as of October 1, 2011 and 

October 2, 2010 (in thousands):  

Foreign currency translation adjustment 
Cumulative change in fair market value of derivative instruments, net 
of  tax                    
Accumulated other comprehensive income 

     $    11,460 

     $      9,789 

 (3,331)
  $      8,129 

 (2,924)
  $      6,865

2011 

2010

The change in fair market value of derivative instruments, net of tax adjustment that is recorded to 
“Accumulated other comprehensive income” is more fully explained in Note 5 – Derivatives and Fair Value 
Measurements. 

Conditional Asset Retirement Obligations: We 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.  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 are reflected in the 
consolidated financial statements at cost because of the short-term duration of these instruments.  Accounts 
receivable are 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 
customers’ credit status. The fair value of capital lease obligations was approximately $15.8 million and 
$18.3 million as of October 1, 2011 and October 2, 2010, respectively.  The fair value of the Company’s 

48 

 
 
 
 
   
 
   
 
Plexus Corp. 
Notes to Consolidated Financial Statements

long-term debt was $274.3 million and $105.2 million as of October 1, 2011 and October 2, 2010, 
respectively.  The fair values of the Company’s derivatives are disclosed in Note 5.  The Company uses 
quoted market prices when available or discounted cash flows to calculate fair value. 

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a 

liability (or exit price) in the principal or most advantageous market for the asset or liability in an orderly 
transaction between market participants on the measurement date. Valuation techniques used to measure fair 
value must maximize the use of observable inputs and minimize the use of unobservable inputs.  The 
accounting guidance establishes a fair value hierarchy based on three levels of inputs that may be used to 
measure fair value.   The input levels are:  

Level 1:  Quoted (observable) market prices in active markets for identical assets or liabilities.  

Level 2:  Inputs other than Level 1 that are observable, such as quoted prices for similar assets or 

liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be 
corroborated by observable market data for substantially the full term of the asset or liability.  

Level 3:  Unobservable inputs that are supported by little or no market activity and that are 

significant to the fair value of the asset or liability. 

Business and Credit Concentrations:  Financial instruments that potentially subject the Company to 

concentrations of credit risk consist of cash, cash equivalents,  trade accounts receivable and derivative 
instruments, specifically related to counterparties.  In accordance with the Company’s investment policy, the 
Company’s cash, cash equivalents and derivative instruments 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 June 2011, the Financial Accounting Standards Board 

(“FASB”) issued an amendment to comprehensive income guidance, which eliminates the option to present 
other comprehensive income (“OCI”) and its components in the statement of shareholders’ equity.  The 
Company can elect to report components of comprehensive income in either (1) a continuous statement of 
comprehensive income or (2) two separate but consecutive statements.  Under the two-statement approach, 
the first statement would include the components of net income, and the second statement would include the 
components of OCI.  This guidance is effective for financial statements issued for fiscal years, and interim 
periods within those years, beginning after December 15, 2011.  The adoption of this guidance is not 
anticipated to have a material impact on our consolidated results of operations, financial position and cash 
flows. 

In May 2011, the FASB issued an amendment regarding common fair value measurement and 

disclosure requirements in U.S. GAAP and international financial reporting standards (“IFRS”). The 
amendments change the wording used to describe many of the requirements in U.S. GAAP for measuring fair 
value and for disclosing information about fair value measurements. To improve consistency in application 
across jurisdictions some changes in wording are necessary to ensure that U.S. GAAP and IFRS fair value 
measurement and disclosure requirements are described in the same way.  The amendment also provides for 
additional accounting guidance and disclosures related to fair value measurements.  This guidance is effective 
for financial statements issued for fiscal years, and interim periods within those years, beginning after 
December 15, 2011.  The adoption of this guidance is not anticipated to have a material impact on our 
consolidated financial position, results of operations and cash flows.  

In October 2009, the FASB issued new accounting guidance for Multiple-Deliverable Revenue 

Arrangements, which establishes a selling price hierarchy for determining the selling price of a deliverable, 
replaces the term “fair value” in the revenue allocation guidance with “selling price,” eliminates the residual 
method of allocation by requiring that arrangement consideration be allocated at the inception of the 
arrangement to all deliverables using the relative selling price method and requires that a vendor determine its 

49 

 
Plexus Corp. 
Notes to Consolidated Financial Statements

best estimate of selling price in a manner that is consistent with that used to determine the price to sell the 
deliverable on a stand-alone basis. This guidance is effective for financial statements issued for fiscal years 
beginning after June 15, 2010.  The Company adopted this guidance beginning October 3, 2010, and the 
adoption did not have a material effect on the Company’s consolidated results of operations, financial 
position, and cash flows.

On April 4, 2008, the Company entered into its 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 
Credit Facility is unsecured and may be increased by an additional $100 million to a total of $200 million (the 
“accordion feature”).  This is possible if the Company has not previously terminated all or any portion of the 
Credit Facility, there is no event of default existing under the credit agreement and both the Company and the 
administrative agent consent to the increase.  The Credit Facility expires on April 4, 2013.  Borrowings under 
the Credit Facility may be either through term loans, revolving or swing loans or letter of credit obligations.  
As of October 1, 2011, the Company has term loan borrowings of $97.5 million outstanding and no revolving 
borrowings under the Credit Facility.  Average outstanding revolving borrowings for the fiscal year ended 
October 1, 2011 were $6.6 million, and there were no draws against the revolving credit facility during the 
fiscal year ended October 2, 2010. 

 The 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 October 1, 2011, the Company was in 
compliance with all debt covenants.  If the Company incurs an event of default, as defined in the Credit 
Facility (including any failure to comply with a financial covenant), the group of banks has the right to 
terminate the remaining Credit Facility and all other obligations, and demand immediate repayment of all 
outstanding sums (principal and accrued interest).  The interest rate on borrowing varies depending upon the 
Company’s then-current total leverage ratio; as of October 1, 2011, the Company could elect to pay interest at 
a defined base rate or the LIBOR rate plus 1.50%.  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 0.375%.  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 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 Credit Facility.  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 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. 

On April 21, 2011, the Company entered into a Note Purchase Agreement (the “Agreement”) with 
certain institutional investors related to $175 million in principal amount of 5.20% Senior Notes, due on June 
15, 2018 (the “Notes”).  The Company issued $100 million in principal amount of the Notes on April 21, 
2011, and the remaining $75 million on June 15, 2011.  The Agreement includes operational and financial 
covenants which include a maximum total leverage ratio, a minimum interest coverage ratio and restrictions 
on additional indebtedness, liens and dispositions, all as defined in the Agreement.  As of October 1, 2011, the 
Company was in compliance with all debt covenants.  The Notes are unsecured and rank at least equally and 
ratably in point and security with the other unsecured and unsubordinated financing facilities of the Company.

Our effective interest rate on the Notes after the treasury rate lock agreement discussed in Note 5 – 
Derivatives and Fair Value Measurements is 4.97%.  Origination fees and expenses associated with the 
Agreement totaled approximately $0.9 million and have been deferred.  These origination fees and expenses 
are being amortized over the seven-year term of the Notes.  Semi-annual interest payments began on June 15, 
2011, and end on June 15, 2018, with full repayment of the total principal of the Notes. 

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

expenses for the Credit Facility and Agreement totaled approximately $0.7 million in each of fiscal 2011, 
2010 and 2009. 

Cash paid for interest in fiscal 2011, 2010 and 2009 was $8.6 million, $9.2 million and $10.5 million, 

respectively.

Derivatives and Fair Value Measurements 

All derivatives are recognized in the accompanying Consolidated Balance Sheets at their estimated 

fair values.  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 currently has cash flow hedges related 
to variable rate debt and forecasted foreign currency payments.  The Company does not enter into derivatives 
for speculative purposes. Changes in the fair value of the derivatives that qualify as cash flow hedges are 
recorded in “Accumulated other comprehensive income” in the accompanying Consolidated Balance Sheets 
until earnings are affected by the variability of the cash flows.  

During the fourth quarter of fiscal 2011, the Company’s Mexican operations entered into forward 

exchange contracts on a rolling basis with a total notional value of $5.9 million as of October 1, 2011.  These 
forward contracts will fix the exchange rates on foreign currency cash used to pay a portion of local currency 
expenses.  The total fair value of these forward contracts was a $1.0 million liability as of October 1, 2011. 

During the second quarter of fiscal 2011, the Company entered into forward exchange contracts to 

fix the exchange rates on foreign currency cash used to pay for capital expenditures related to the 
construction of our fourth facility in Malaysia.  As of October 1, 2011, the total notional value of the forward 
contracts was $2.5 million and the total fair value of these forward contracts was a $0.1 million liability.     

The Company’s Malaysian operations have also entered into forward exchange contracts on a rolling 

basis with a total notional value of $57.2 million as of October 1, 2011.  These forward contracts will fix the 
exchange rates on foreign currency cash used to pay a portion of local currency expenses.  The total fair value 
of these forward contracts was a $1.5 million liability as of October 1, 2011 and a $2.6 million asset as of 
October 2, 2010. 

During the second quarter of fiscal 2011, the Company entered into two separate treasury rate lock 
contracts to hedge the variability of the fixed interest rate on the then forecasted issuance of $175 million of 
fixed rate debt using a treasury lock transaction.  The fixed interest rates for each of these contracts were 
2.77% and 2.72%, respectively, with a combined notional value of $150 million.  On April 4, 2011, the 
Company entered into a final treasury rate lock transaction for the remaining $25 million of exposure at a rate 
of 2.88%.  On April 8, 2011, when the fixed interest rate for the debt issuance was determined, all three 
treasury rate lock contracts were settled and the Company received proceeds of $2.3 million, which is being 
amortized over the seven year term of the related debt.   

In June 2008, the Company entered into three interest rate swap contracts related to the $150 million 

in term loans under the Credit Facility that had an initial 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 Credit Facility into fixed 

53

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.  The total fair value of these 
interest rate swap contracts was a $5.2 million liability as of October 1, 2011 and a $9.0 million liability as of  
October 2, 2010.  As of October 1, 2011, the total remaining combined notional amount of the Company’s 
three interest rate swaps was $97.5 million.

The fair value of interest rate swaps and foreign currency forward contracts is determined using a 

market approach, which includes obtaining directly or indirectly observable values from third parties active in 
the relevant markets.  The primary input in the fair value of the interest rate swaps is the relevant LIBOR 
forward curve.  Inputs in the fair value of the foreign currency forward contracts include prevailing forward 
and spot prices for currency and interest rate forward curves.

The Company recorded income tax expense of $2.8 million and $0.9 million for fiscal 2011 and 

fiscal 2010, respectively.  The Company recorded income tax benefit of $(0.9) million for fiscal 2009.  The 
increase to the income tax expense recorded in fiscal 2011 as compared to fiscal 2010 and fiscal 2009 is 
primarily due to the change in the mix of income in the tax jurisdictions in which we operate.  The difference 
in our effective income tax rate as compared to our normal statutory rate is primarily due to the effect of pre-
tax income in Malaysia and Xiamen, China, where we benefit from reduced effective tax rates due to tax 
holidays.

During the preparation of the Company’s fiscal 2011 consolidated financial statements, the 
Company performed an analysis of all available evidence, both positive and negative, regarding the need for a 
valuation allowance against our deferred tax assets, consistent with the provisions of ASC Topic 740, 
“Income Taxes.”  The Company’s U.S. operations generated losses during the fiscal 2009, 2010 and 2011 
years.  While we believe these losses could be a significant factor in establishing such an allowance, we 
believe that based on the weight of all the evidence, both positive and negative, it is more likely than not that 
the Company will be able to utilize its U.S. net deferred tax assets of approximately $21.7 million.

Plexus Corp. 
Notes to Consolidated Financial Statements

The positive evidence relied upon is as follows: 1) orders for a new large U.S. industrial/commercial 

customer are currently projected to significantly increase in fiscal 2012, which we believe would result in 
income for the Company’s U.S. operations in fiscal 2012 and beyond; 2) the effect of the deep U.S. recession 
during this period was considered atypical; 3) the Company’s U.S. operations created cumulative pretax 
income for fiscal years 2006 through 2008 of more than $150 million; 4) the federal tax losses in fiscal 2009 
and 2010 were able to be fully utilized through loss carrybacks to prior years; and 5) the federal loss 
carryforward at the end of fiscal 2011 has a 20 year carryforward period. 

As a result of using the with-and-without method under the requirements for accounting for stock-
based compensation, the Company recorded a valuation allowance for state taxes 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 
reversed approximately $0.1 million of this valuation allowance with corresponding credits to additional 
paid-in capital in fiscal 2009.  As of the end of fiscal 2010 there was a valuation allowance of $1.0 million for 
federal and state taxes against the amount of net operating loss and credit carryforwards related to tax 
deductions in excess of compensation expense for stock options.   During fiscal 2011 the Company recorded 
an additional valuation allowance of $1.3 million.  As a result, we had a remaining valuation allowance of 
approximately $2.3 million related to tax deductions associated with stock-based compensation as of October 
1, 2011.    

In addition, there is a remaining valuation allowance of $1.6 million as of October 1, 2011, related to 
various state deferred income tax assets where it is more likely than not that the asset will not be realized due 
to a lack of sustained profitability and limited carryforward periods in these states. 

During fiscal 2011 the Company added a valuation allowance of $0.3 million and $0.9 million in the 

United Kingdom and Romania, respectively to offset the increase in net deferred tax assets in those 
jurisdictions which, more likely than not, will not be realized. 

On November 1, 2009, Mexico adopted tax reform legislation that took effect January 1, 2010, and 
provides for a temporary increase in its income tax and value added tax rates from 28% to 30% and 15% to 
16%, respectively, along with certain other changes.  These laws did not have a material impact on our 
effective income tax rate in fiscal 2011, 2010 or 2009; however, they could have a material effect on future 
periods.  On November 5, 2009, the United States adopted the “Worker, Homeownership, and Business 
Assistance Act of 2009”, which provides for an increase in the net operating loss carryback period from two 
years to five years for tax periods beginning or ending in calendar years 2008 and 2009, along with certain 
other tax law changes.  This law did not have a material impact on our effective tax rate in fiscal 2011, 2010 
or 2009 and we do not currently believe that it will create a material impact on our effective income tax rate 
in future periods.  

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 that began in calendar 2008.  This law did not 
have a material effect on our income taxes for our fiscal 2011, 2010 or 2009 tax years.  However, depending 
upon the relative amount of income earned in China in the future, the increased tax rates on our China income 
could have a material effect.   

On July 19, 2011, the United Kingdom enacted The Finance (No. 3) Act 2011, which reduced its 

corporate income tax rate from 28% to 26% effective April 1, 2011 and to 25% effective April 1, 2012.   This 
law did not have a material impact on our effective income tax rate in fiscal 2011; however, it could have a 
material effect on future periods.  In July 2005, 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 
years 2011, 2010 and 2009, management provided income tax expense for the effect of the Finance Act on 
the non-deductibility of this interest expense based on the current 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 Xiamen, China subsidiaries.  

These tax holidays expire in 2024 and 2013, respectively, and are subject to certain conditions with which the 
Company expects to comply.  In fiscal 2011, 2010 and 2009, these subsidiaries generated income, which 
resulted in tax reductions of approximately $21.7 million ($0.57 per basic share), $23.0 million ($0.58 per 
basic share) and $15.2 million ($0.38 per basic share), 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 was approximately $406.8 million as of October 1, 2011.  If such 
earnings were repatriated, additional tax expense may result, although the calculation of such additional taxes 
is not practicable at this time.  

As of October 1, 2011, the Company had approximately $75.6 million of state net operating loss 

carryforwards that expire between fiscal 2012 and 2029.    

Cash  refund  for  income  taxes  in  fiscal  2011  was  $2.2  million,  and  cash  paid  for  income  taxes  in 

fiscal 2010 and 2009 was $3.5 million and $2.9 million, respectively. 

The Company has approximately $7.4 million of uncertain tax benefits as of October 1, 2011.  The 
Company has classified these amounts in the Consolidated Balance Sheets as “Other liabilities” (noncurrent) 
to the extent that payment is not anticipated within one year.  Presented below is a reconciliation of the 
beginning and ending amounts of unrecognized income tax benefits (in thousands):

Approximately $6.3 million and $4.8 million, respectively of the balance as of October 1, 2011, and 

October 2, 2010 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 $0.7 million, $0.5 million and $0.3 million as of October 1, 2011, October 2, 2010 and October 
3, 2009, respectively. The Company recognized $0.2 million of expense for accrued penalties and net accrued 
interest in the Consolidated Statements of Operations for the fiscal year ended October 1, 2011. 

During the second quarter of fiscal 2009, tax expense decreased by approximately $1.4 million, 
consisting of approximately $1.6 million, including interest, related to the conclusion of federal and state 
audits, which resulted in a reduction of the liability related to uncertainty in income taxes, offset by an 
additional provision of $0.2 million for changes in state tax laws. 

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.

Shareholders’ Equity  

On February 16, 2011 the Company’s Board of Directors approved a share repurchase program that 

authorized the Company to repurchase up to $200 million of common stock.  On August 15, 2011, the 
Company completed its share repurchase program; a total of 6.3 million shares were purchased at a volume-
weighted average of $31.69 per share.    

Pursuant to the Company's Rights Agreement, each preferred share purchase right (a "Right") 

entitles the registered holder to purchase from the Company one one-hundredth of a share of the Company's 
Series B Junior Participating Preferred Stock, $0.01 par value per share (“Preferred Share"), at a price of 
$125.00 per one one-hundredth of a Preferred Share, subject to adjustment.  The Rights are exercisable only 
if a person or group acquires beneficial ownership of more than 20% of the Company's outstanding common 
stock or commences, or announces an intention to make, a tender offer or exchange offer that would result 
in such person or group acquiring the beneficial ownership of more than 20% of the Company's common 
stock.  The Rights expire on August 28, 2018, subject to extension.

purchase approximately 1.3 million, 1.2 million and 2.7 million shares, respectively, 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 our common shares and, therefore, their effect would be 
antidilutive.  In fiscal 2009, restricted stock units (“RSUs”) of approximately 20,000 were outstanding but

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 2021.  Rent expense under all operating leases for fiscal 2011, 2010 and 
2009 was approximately $12.8 million, $11.8 million and $11.9 million, respectively.  Renewal and purchase 
options are available on certain of these leases.

Restructuring and Asset Impairment Charges 

Fiscal 2011 and fiscal 2010 restructuring and asset impairment charges: For fiscal 2011 and fiscal 

2010, the Company did not incur any restructuring or impairment charges.  

Fiscal 2009 restructuring and asset impairment charges: For fiscal 2009, we recorded pre-tax 

restructuring and asset impairment charges of $8.6 million, related to goodwill impairment in our EMEA 
reportable segment, the closure of our Ayer, Massachusetts (“Ayer”) facility and the reduction of our 
workforce across our facilities in the United States and Juarez, Mexico (“Juarez”).  The details of these fiscal 
2009 restructuring actions are listed below: 

Goodwill Impairment:  During the second quarter of fiscal 2009, the Company recorded a goodwill 
impairment charge of $5.7 million, writing off the entire carrying value of our goodwill related to our Kelso, 
Scotland (“Kelso”) facility.  The impairment charge was driven by macroeconomic conditions that 
contributed to an overall reduction in demand for the Company’s offerings from the Kelso facility.  These 
conditions led to an “interim triggering event”, leading management to perform an interim goodwill 
impairment test.  This test resulted in the determination that the carrying value of the goodwill relating to 
Kelso was fully impaired and therefore an impairment charge of $5.7 million was recorded.    

Ayer Facility Closure:  During the third quarter of fiscal 2009, we closed our Ayer facility.  In fiscal 

2009, we recorded pre-tax restructuring charges of $0.4 million, related to the disposal of certain assets and 
costs to exit this leased facility.       

Other Restructuring Charges.  In fiscal 2009, we recorded pre-tax restructuring charges of $2.0 

million related to severance at facilities in the United States as well as Juarez.  These workforce reductions 
affected approximately 450 employees.  We also recorded approximately $0.5 million of asset impairment 
charges at Corporate.

Benefit Plans 

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

Effective January 1, 2010, the Company began matching employee contributions up to 4 percent of eligible 
earnings.  Previously, the Company matched employee contributions up to 2.5 percent of eligible earnings.  
The Company’s contributions for fiscal 2011, 2010 and 2009 totaled $5.8 million, $4.9 million and $2.9 
million, respectively. 

Stock-based Compensation Plans: The Company’s shareholders approved the Plexus Corp. 2008 

Long-Term Incentive Plan (the “2008 Plan”), which was last approved by shareholders in February 2011, is 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”), unrestricted stock awards (“SAs”) and 
performance stock awards, in addition to cash incentive 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, cash incentive awards of up to $4.0 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, 
RSUs and other awards under the 2008 Plan as well as accelerate the vesting of such awards.  Generally, 
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 replaced 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 exercise price of each stock option granted must not have been less than the fair market value 
on the date of grant.  The 2005 Plan terminated upon the approval of the 2008 Plan, except that outstanding 
awards continue until expiration.   

Individual stock option and SARs grants are determined annually, but granted on a quarterly basis.  

However, grants of RSUs are generally made only on an annual basis.  Beginning in fiscal 2011, the 
Company discontinued the use of long-term cash awards and increased the number of RSUs to provide 
equivalent value.  In fiscal 2009, the Company made a special grant consisting solely of RSUs to certain key

employees (excluding our Chief Executive Officer) to encourage retention, but did not make similar special 
grants in fiscal 2011 or fiscal 2010.   

For options issued to the members of the Board of Directors in fiscal 2009, 50 percent of their stock 

options vested immediately at the date of grant and their remaining stock options vested on the first 
anniversary of the grant date.  Options issued to the members of the Board of Directors in fiscal 2011 and 
2010 vested immediately on the date of grant.  In fiscal 2011 and fiscal 2010, the Company granted members 
of the board of directors SAs, which vested immediately on grant.  

In fiscal 2011, under the 2008 Plan, the Company granted options, which had a term of ten years, to 
purchase 0.3 million shares of the Company’s common stock and 0.3 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, all of which vest on the third anniversary of grant, and the Committee granted SAs for 0.1 million 
shares of common stock. 

In fiscal 2010, under the 2008 Plan, the Company granted options, which had a term of ten years, to 
purchase 0.3 million shares of the Company’s common stock and 0.3 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 $0.9 million, all of which vest on the third anniversary of grant.  
In addition, in fiscal 2010, the Committee granted SAs for 0.1 million shares of common stock. 

In fiscal 2009, under the 2008 Plan, the Company granted options, which had a term of ten years, to 
purchase 0.3 million shares of the Company’s common stock and 0.3 million stock-settled SARs, which had a 
term of seven years.  Additionally, the Committee made awards of RSUs for 0.2 million shares of common 
stock and long-term cash awards that totaled $1.0 million, all of which vest on the third anniversary of grant. 

The Company recognized $11.0 million, $9.5 million, and $9.4 million of compensation expense 
associated with stock options, SARs, RSUs and SAs for the fiscal years ended October 1, 2011, October 2, 
2010 and October 3, 2009, respectively.  The related deferred tax benefit recognized was $3.7 million, $3.2 
million, and $2.4 million for the fiscal years ended October 1, 2011, October 2, 2010, and October 3, 2009, 
respectively.

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 
option and SAR lives.  The expected option and SAR lives represent the period of time that the options and 
SARs granted are expected to be outstanding and were based on historical experience.   

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

October 1, 2011, October 2, 2010 and October 3, 2009 were $13.40, $14.25 and $8.72, respectively.  The fair 
value of each option and SAR grant was estimated at the date of grant using the Black-Scholes option-pricing 
model based on the assumption ranges below:

and October 3, 2009 were $3.6 million, $3.1 million and $6.3 million, respectively. 

For the fiscal years ended October 1, 2011, October 2, 2010, and October 3, 2009, the total intrinsic 

value of options and SARs exercised was $6.5 million, $8.5 million and $1.2 million, respectively. 

As of October 1, 2011, there was $7.7 million of unrecognized compensation cost related to non-
vested options and SARs that is expected to be recognized over a weighted average period of 1.29 years.

The Company uses the fair value at the date of grant to value RSUs and SAs.  The fair value of 
RSUs and SAs that vested for the fiscal year ended October 1, 2011 was $0.6 million.  There was 88,112 
RSUs and 10,000 SAs that vested during the fiscal year ended October 1, 2011.  There were not any RSUs 
and 16,000 SAs that vested during the fiscal year ended October 2, 2010 and there were not any RSUs or SAs 
that vested during the fiscal year ended October 3, 2009.   

As of October 1, 2011, there was $5.1 million of unrecognized compensation cost related to RSU 

awards that is expected to be recognized over a weighted average period of 1.8 years. 

Deferred Compensation Arrangements:  The Company has 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.   In August 2009, amendments 
were entered into in order to align the provisions regarding the determination of payment amounts to a fixed 
15-year annual installment payment stream.  The amendments were consistent with the intent of the original 
agreements and with the manner in which the agreements had operated in practice.  

The Company has 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.  

The SERP operates under 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.  In fiscal 2011, 
2010 and 2009, the Company made contributions to the participants’ SERP accounts in the amount of $0.3 
million, $0.2 million and $0.2 million, respectively.     

As of October 1, 2011 and October 2, 2010, the SERP assets held in the Trust totaled $6.2 million 
and $6.0 million, respectively, and the related liability to the participants totaled approximately $3.9 million 
and $4.0 million as of October 1, 2011 and October 2, 2010, 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 non-current “Other assets” and non-current “Other liabilities”, respectively, in the accompanying 
Consolidated Balance Sheets. 

Other:  The Company currently does not and is not obligated to provide any postretirement medical 

or life insurance benefits to employees.

Litigation 

In fiscal 2010, the Company incurred approximately $1.1 million of costs relating to non-
conforming inventory received from a supplier.  The Company reached a settlement with the supplier during 
the first quarter of fiscal 2011 for $0.9 million, which was received and recorded in selling and administrative 
expenses in fiscal 2011.     

We were notified in April 2009 by U.S. Customs and Border Protection (“CBP”) of its intention to 

conduct a customary Focused Assessment of our import activities during fiscal 2008 and of our processes and 
procedures to comply with U.S. Customs laws and regulations.  During September 2010 the Company 
reported errors relating to import trade activity from July 2004 to the date of Plexus’ report.  CBP has 
indicated that on-site fieldwork for the audit was completed as of June 2011 and the Company is currently 
awaiting final determination of CBP duties and fees.  Plexus has agreed that it will implement improved 
processes and procedures and review these corrective measures with CBP.    We recorded an accrual in other 
current accrued liabilities in the first quarter of fiscal 2010 when the amount became estimable and probable, 
which was not material to the financial statements.  At this time, we do not believe that any deficiencies in 
processes or controls or unanticipated costs, unpaid duties or penalties associated with this matter will have a 
material adverse effect on Plexus or the Company’s consolidated financial position, results of operations or 
cash flows.

In December 2009, the Company received settlement funds of approximately $3.2 million related to 
a court case in which the Company was a plaintiff.  The settlement related to prior purchases of inventory and 
therefore was recorded as a reduction of cost of sales.   

The Company is party to certain other lawsuits in the ordinary course of business.  Management 

does not believe that these proceedings, individually or in the aggregate, will have a material adverse effect 
on the Company's consolidated financial position, results of operations or cash flows.

Reportable Segments, Geographic Information and Major Customers 

Reportable segments are defined as components of an enterprise about which separate financial 

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

In the first quarter of fiscal 2011, we completed our migration to a regional reporting structure, and 

as a result, modified our reportable segments.  See Note 1 – Description of Business and Significant 
Accounting Policies for further information. 

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

data to evaluate performance and allocate the Company's resources on a regional 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, other 
income (loss), and income taxes. Corporate and other costs primarily represent corporate selling and 
administrative expenses, and restructuring and impairment costs, if any. 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.(cid:3)(cid:3)

Long-lived assets as of October 1, 2011 and October 2, 2010 exclude other long-term assets and 

deferred income tax assets which totaled $30.5 million and $28.7 million, respectively. 

Restructuring and asset impairment charges are not allocated to reportable segments, as management 

excludes such charges when assessing the performance of the reportable segments, but rather includes such 
charges within the “Corporate and other costs” section of the above table of operating income (loss). In fiscal 
2011 and fiscal 2010 the Company did not incur any restructuring or asset impairment charges.  In fiscal

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 agreements have 
extended broader indemnification, 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.
