ANNUAL MEETING OF SHAREHOLDERS 
FEBRUARY 13, 2013 

COMMONLY ASKED QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING 

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

A:  On or about December 14, 2012, 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 13, 2013 

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

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 
•  Rainer Jueckstock 

•  Peter Kelly 
•  Phil R. Martens 
•  Michael V. Schrock 
•  Mary A. Winston 

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

independent auditors for 2013. 

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 2013; 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.    In  addition,  assuming  a  quorum  is  present,  the 
results of the advisory vote to approve the compensation of the Company’s named executive officers will also be 
determined by a majority of shares voting on such matter.  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 to approve 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 6, 2012, which is the “Record Date.”  As of the Record Date, Plexus had 34,968,050 
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, Dean A. Foate, Ginger M. Jones 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 6, 2012, 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 
2014 ANNUAL MEETING? 

A:  The Secretary must receive a shareholder proposal no later than August 16, 2013, in order for the proposal to be 
considered  for  inclusion  in  our  proxy  materials  for  the  2014  annual  meeting.  The  2014  annual  meeting  of 
shareholders is tentatively scheduled for February 12, 2014.  To otherwise bring a proposal or nomination before the 
2014  annual  meeting,  you  must  comply  with  our  bylaws.    Currently,  our  bylaws  require  written  notice  to  the 
Secretary between October 5, 2013, and October 30, 2013.  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

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. 

John  L.  Nussbaum,  a  co-founder  of  Plexus  and  our  former  Chief  Executive  Officer,  will  be  retiring  as 
Chairman  of  the  Board  effective  as  of  the  annual  meeting  on  February  13,  2013.    Plexus  and  the  board  both 
sincerely thank Mr. Nussbaum for his years of dedicated service and many valuable contributions to Plexus.

Board of Directors Meetings 

CORPORATE GOVERNANCE 

The board of directors held four meetings during fiscal 2012.  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  2012  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 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 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  2012  represented  less  than  two-tenths  of  one 
percent of each of Plexus’ and NXPs annual revenues. 

• Mr.  Schrock  is  an  executive  officer  of  Pentair  Ltd.,  which  is  a  supplier  to  Plexus.    Plexus’ 
payments  to  Pentair  in  fiscal  2012  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, and that Mr. Jueckstock would be “independent” if elected to 
the  board.    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.

Board Leadership Structure  

Mr.  Nussbaum,  our  former  Chief  Executive  Officer,  currently  serves  as  the  Chairman  of  the  Board.  As 
previously announced, Mr. Nussbaum will be retiring and Mr. Foate, our current Chief Executive Officer, has been 
elected as Chairman, effective after the annual meeting on February 13, 2013.  The Company believes that having 
Mr. Nussbaum serve as Chairman in recent years has been an appropriate leadership structure for the board because 
Mr. Nussbaum, as our former CEO, has extensive knowledge of the Company and the EMS industry, which have 
been valuable in communicating with and leading the board in his role as Chairman.  

In  connection  with  its  succession  planning  efforts,  the  board  evaluated  its  leadership  structure  and 
determined that upon Mr. Nussbaum’s retirement, Mr. Foate would be appointed as Chairman primarily due to his 
in-depth  knowledge  of  the  Company  and  EMS  industry,  keen  understanding  of  the  Company’s  operations  and 
strategies,  proven  leadership  and vision  for  Plexus,  which  position  him  to  be  able  to  provide  strong  and  effective 
leadership of the board going forward.  In addition, the board believes that Mr. Foate will be in the best position as 
Chairman and CEO to lead board discussions regarding the Company’s business and strategy, and to help the board 
respond quickly and effectively to any challenges faced by the Company.   

The  board  does  not  have  a  policy  that  requires  the  separation  of  the  roles  of  Chairman  and  CEO,  and 
believes the Company should adopt the board leadership structure that best serves its needs at any particular time.  
Pursuant  to  the  Company’s  Corporate  Governance  Guidelines,  if  the  Chairman  is  also  the  CEO,  the  independent 
directors, meeting in executive session, will elect a lead director from among the independent directors.  Therefore, 
in  connection  with  the  leadership  changes  discussed  above,  in  November  2012,  the  independent  directors  of  the 
Company’s board elected Mr. Schrock as lead director, also effective after the annual meeting on February 13, 2013.  
The  Company  believes  that  the  designation  of  an  independent  lead  director,  whose  duties  are  described  below, 
provides  essentially  the  same  benefits  as  having  an  independent  chairman  in  terms  of  oversight,  access  and  an 
independent voice with significant input into corporate governance. 

The  duties  of  the  board’s  lead  director  include:  (i)  presiding  at  all  meetings  of  the  board  at  which  the 
Chairman is not present, including executive sessions of the independent directors; (ii) serving as liaison between 
the  Chairman  and  the  independent  directors;  (iii)  together  with  the  Chairman,  approving  the  agendas  for  board 
meetings;  (iv) together with  the  Chairman, approving  meeting schedules  to  assure  that  there  is  sufficient  time  for 
discussion of all agenda items; (v) providing input to the Chairman as to the content, quality, quantity and timeliness 
of  information  from  Company  management  to  the  board;  (vi)  having  the  authority  to  call  meetings  of  the 
independent directors and develop the agendas for such meetings with input from the other independent directors; 
(vii) serving as a liaison for consultation and direct communication with major shareholders; and (viii) performing 
such other duties as the board or Chairman may from time to time delegate. 

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, 
compliance and ethics. 

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.  Mr. Jueckstock’s prospective committee membership 
has not yet been determined. 

Audit Committee 

The  Audit  Committee  met  eight  times  in  fiscal  2012.    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.” 

Audit Committee Financial Experts

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

Compensation and Leadership Development Committee 

The Compensation and Leadership Development Committee (in this subsection, the “Committee”) held six 
meetings  during  fiscal  2012.    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 2012. 

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  2012,  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 several 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 

14 

 
 
 
 
 
 
 
 
 
 
 
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 2012 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 2013 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 

15 

 
resources management to review competitive practices and overall plan expense; the CEO is not present for these 
discussions.    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  Committee  is 
directly  responsible  for  the  appointment,  termination,  compensation  and  oversight  of  the  work  of  any  such 
compensation consultant(s). The Company provides appropriate funding, as determined by the Committee, for the 
payment of compensation to the compensation consultant(s) employed by the Committee.  The Committee currently 
retains Towers Watson as its compensation consultant. 

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 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.  In future years, the Committee may retain Tower Watson or another independent compensation consultant to 
conduct a detailed analysis of the Company’s executive compensation package.

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 Committee 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.  After considering the factors set forth in the final SEC and proposed 
Nasdaq rules, the Committee does not believe its relationship with Towers Watson has given rise to any conflict of 
interest. 

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  2012  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 five times in 
fiscal 2012.  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 

16 

 
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. 

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.”

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 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,” 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 2012, each Plexus director who was not a full-time Plexus officer or employee (all directors 
except Mr. Foate, who does not receive additional fees for serving on the board) received an annual director’s fee of 
$55,000  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  in  such  roles;  the  Audit  Committee  Chair 
received  $15,000,  the  Compensation  and  Leadership  Development  Committee  Chair  received  $12,500  and  the 
Nominating and Corporate Governance Committee Chair received $10,000.  Mr. Nussbaum received an additional 
fee of $75,000 in fiscal 2012 for serving as Plexus’ non-executive Chairman of the Board.  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 2013, board and committee meeting attendance fees, and the 
chairman of the board fee, have been eliminated.  The annual director’s fee will increase to $65,000 and the lead 
director will receive an additional annual fee of $20,000 for serving in that role.  Committee chair fees will remain 
the same.  The other members of the committees will receive annual retainers for their service as follows:  Audit 
Committee  -  $9,000;  Compensation  and  Leadership  Development  Committee  -  $7,500;  and  Nominating  and 
Corporate Governance Committee - $5,250. 

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.  In fiscal 2012, stock options were granted to directors quarterly, at the same time as employee grants, and 
vested  immediately  on  the respective grant dates.   The  exercise price of  each  stock option grant was  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 were granted to directors at the same time as employee equity grants during the 
second quarter of the fiscal 2012.  Beginning in calendar year 2013, it is anticipated that directors will be granted 
restricted stock units, instead of a mix of stock options and unrestricted stock awards, during the second quarter of 
the fiscal year; the restrictions on these awards will lapse on the first anniversary of the applicable grant date.  The 
use  of  equity  awards  is  designed  to  align  directors’  interests  with  the  long-term  ownership  interests  of  our 
shareholders.

(1)  Includes annual retainer, meeting, committee and chairmanship fees and, in the case of Mr. Nussbaum, his fee 

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  2012.    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  10  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 2012, 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 
September  29,  2012.    The  Company  began  granting  unrestricted  stock  awards  to  directors  in  fiscal  2010; 
restricted stock awards were not granted to directors in fiscal 2012 or in any prior years.

Each non-employee director serving at the time was awarded options for 1,250 shares on each of October 31, 
2011, January 23, 2012, April 23, 2012, and July 23, 2012.  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  23,  2012,  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 Market on that date was 
$36.79.  Messrs. Böer, Cortinovis, Martens and Nussbaum and Ms. Winston each elected to defer receipt of the 
2012 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  2012  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. 

Retirement Arrangement for Mr. Nussbaum 

Mr. Nussbaum is a former executive officer of Plexus.  He ceased being considered an executive officer or 
employee of Plexus when he retired as our Chief Executive Officer in 2002, and has been eligible to receive board 
fees and equity grants as a non-employee director since that time.  However, as a consequence of his many years of 
service  as  an  executive  officer  of  Plexus,  he  continues  to  be  compensated  under  deferred  compensation 
arrangements which were put in place during his service as an executive officer and as the non-executive Chairman 
of the Board. 

In  1996,  the  Compensation  and  Leadership  Development  Committee  established  special  retirement 

arrangements for Mr. Nussbaum 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  fiscal  2002  and  prior  years.    Mr. Nussbaum  has  received 
payments  under  the  special  retirement  arrangements  since  2002,  including  payments  of  $338,660  for  fiscal  2010, 
$352,742 for fiscal 2011 and $366,853 for fiscal 2012.  

The contributions for Mr. Nussbaum’s special retirement arrangement are invested in life insurance policies 
on  his  life,  which  were  acquired  by  Plexus.    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,  death  benefit  payments  specified  in  the  arrangement 
become due.

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, the Company believes that 
during fiscal 2012 our insiders have complied with all applicable Section 16(a) filing requirements.

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  (“RSUs”)  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. 

Focus on Growth and Return on Invested Capital 

The  Committee  seeks  to  maintain  a  compensation  program  that  aligns  executive  compensation  with 
creating and maximizing value for our shareholders.  The Committee and Company believe that shareholder value is 
maximized through revenue growth and generating a return on invested capital (“ROIC”) exceeding the Company’s 
weighted average cost of capital (“WACC”).  These metrics together, when achieved, deliver growth and economic 
profit.  The importance of achieving revenue growth and ROIC goals has been emphasized by making a substantial 
component of each executive officer’s compensation dependent on the Company’s achievement of these goals, with 
executives  maximizing  their  annual  incentive  compensation  opportunity  if  the  Company  achieves  its  enduring 
financial  goals  of  15%  organic  revenue  growth  and  an  ROIC  that  exceeds  the  Company’s  WACC  by  500  basis 
points.  In fiscal 2012, executive compensation was further weighted toward achieving these goals.  The Company’s 
annual incentive compensation plan uses return on capital employed (“ROCE”), a derivative measure to ROIC that 
excludes  taxes  and  equity-based  compensation  costs  because  these  items  do  not  reflect  the  Company’s  operating 
performance, which is what the plan is designed to reward.

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 

Annual Incentive 

Long-Term Incentives 

Benefits

Retirement Plans 

Agreements 

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. 

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.  As distinguished from equity-based 
compensation, which is significantly affected by market factors that may be unrelated to 
our results, the design of the VICP offers incentives based on our direct performance.  
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 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 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.  One of 
these  retirement  plans,  the  401(k)  Retirement  Plan  (the  “401(k)  Plan”),  includes  a 
Plexus  stock  fund  as  one  of  its  investment  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’ 2012 annual meeting of shareholders, the Company held a shareholder advisory vote to approve 
executive compensation.  Over 94% 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 55% to 70% of base salary in fiscal 2012 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 110%, 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 2012 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 

24 

 
 
 
 
 
 
 
 
 
 
 
expects  to  make  determinations  of  base  salary  adjustments  for  our  executive  officers  in  December  2012, 
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.   

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.   

2012 Base Salary Adjustments.  Base salary adjustments for fiscal 2012 were approved by the Committee 
in  December  2011.    For  fiscal  2012,  the  Committee  did  not  increase  our  CEO’s  base  salary,  which 
remained near the intended 50th percentile of peer group and market comparisons.  Instead, the Committee 
placed  a  greater  emphasis  on  annual  and  long-term  incentive  opportunities  since  they  are  performance-
based, represent compensation that is at risk, promote the creation of shareholder value and are intended to 
further align the interests of our CEO with those of our shareholders.  Our CEO’s base salary is 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 2.6% to 7.1%; 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. The  Committee believed that base salaries for our other executive officers were aligned with 
peer group and market comparisons; therefore, fiscal 2012 base salary percentage increases were generally 
lower than in previous years.  Similar to the adjustments to the compensation package for our CEO noted 
above,  a  greater  emphasis  was  placed  on  annual  and  long-term  incentive  opportunities  in  order  to  more 
strongly link executive compensation with Company performance and shareholder returns  Presented below 
are  the  fiscal  2012  base  salaries  and  percentage  increases  as  compared  to  fiscal  2011  for  our  named 
executive officers:

Annual Incentive 

Plan Structure. The VICP provides annual cash incentives to approximately 3,400 participants, including 
our CEO and other executive officers.  For executive officers, 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 2012 the targeted award opportunity for our CEO was 110% of base salary, and the 
targeted  award  opportunities  for  other  executive  officers  varied  from  55%  to  70%  of  base  salaries;  the 
award  opportunities  for  non-executive  officer  participants  varied  from  3%  to  45%  of  base  salaries.    The 
targeted  award  opportunity  for  our  CEO  was  increased  by  ten  percentage  points  in  fiscal  2012  to  better 
align with peer group and market comparisons, and, in combination with the lack of a base salary increase, 
to  shift  a  higher  portion  of  his  potential  compensation  toward  performance-based  elements  of  our 
compensation program.  Annual incentive opportunity targets for our other executive officers increased by 
five to ten percentage points in fiscal 2012 as a result of adjustments for  market competitiveness and, in 
certain cases, increases in responsibilities, as well as an increased emphasis on incentive compensation. In 
addition, offering a greater percentage of compensation at risk was intended to more strongly link executive 
compensation with Company performance and shareholder returns. 

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  2012  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 2012.  

26 

 
2012 Plan Design – Company Goals. The specific corporate financial goals for fiscal 2012, each of which 
stood independently of the other with regard to award opportunities, were revenue and ROCE.  The goals 
were  chosen  because  they  aligned  performance-based  compensation  to  the  key  financial  metrics  that  the 
Company used internally to measure its ongoing performance and that it used in its financial plans.  Our 
fiscal 2012 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  and  excluding 
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 taxes and equity-based compensation costs because these factors do 
not reflect the operating performance of the Company, which is what the VICP is intended to reward.  For 
the  same  reasons,  the  Committee  may,  at  its  discretion,  exclude  restructuring  costs  and/or  non-recurring 
charges when determining ROCE for VICP awards; no such discretion was exercised by the Committee in 
fiscal 2012. 

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 2012, in accordance with Plexus’ strategic plan, the Committee set performance levels for each 
metric with a focus on achieving our enduring financial goals using the philosophy below:  

Threshold 

Target 

Revenue 

ROCE

Growth approximately 
equal to inflation 
Equal to Plexus’ 
WACC plus 300 basis

Midpoint between threshold 
and maximum payout

We  believe  that  setting  the  maximum  payout  levels for revenue  and  ROCE  consistent  with  our  enduring 
financial  goals  fully  aligns  employees  with  financial  results  that  maximize  value  to  our  shareholders, 
without encouraging inappropriate risk-taking.  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 to be challenging, but achievable, based on industry conditions and Plexus’ financial plan.   

The  following  table  sets  forth  the  fiscal  2012  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  fiscal  2012,  revenue  was  $2,306.7  million  and  ROCE  was  18.7%.    Therefore,  the  Company’s 
performance was below the threshold level for revenue and between the target and maximum payout levels 
for  ROCE;  as  a  result,  Plexus  paid  awards  to  executive  officers  and  other  employees  based  on  ROCE

2012 Plan Design – Individual Objectives. Individual participants typically set several individual objectives 
for the plan year.  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  90.3%  to  95.5%  of  the 
individual’s potential payout for personal objectives, with the CEO achieving 93.2%.  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 2012:  

– 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;  and

Company.

– Ginger  M.  Jones:    Ms.  Jones’  individual  objectives  related  to:    designing  strategies  for  the 
continued development and deployment of a global information technology (“IT”) platform;

Long-Term Incentives 

Plan Structure.  Total compensation, consistent with practices in our industry, places a particular emphasis 
on  equity-based  compensation  for  executive  officers.    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  2012.    The  reported  values  of  the  long-term  incentive  opportunities  under  equity 
plans can vary significantly from year to year as a percentage of total direct compensation because they are 
determined  by  valuing  the  equity-based  awards  on  the  same  basis  that  we  use  for  financial  statement 
purposes; that value depends significantly on our stock price and its volatility at the time of the awards.   

The Committee’s long-term incentive strategy allows for use of a portfolio approach when granting awards.  
For  fiscal  2012  the  Committee  used,  and  going  forward  the  Committee  intends  to  continue  using,  a 
combination  of  stock  options  and  RSUs  in  order  to  align  all  long-term  incentives  with  the  Company’s 
overall performance and shareholder returns. 

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. 
In  addition  to  promoting  retention,  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 

29 

 
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 senior non-executive key employees who are eligible for equity awards, Plexus uses a mix of 
RSUs and 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  minimize  dilution.  For  other  non-executive 
employees eligible for equity awards, Plexus uses RSUs for the reasons noted above. 

The  allocation  formulas  used  in  fiscal  2012  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.   

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  2012,  options  for  91,750  shares  and  38,000  RSUs  were  granted  to  the  CEO,  and  options  for 
171,000 shares and 71,600 RSUs were granted to the other executive officers as a group.  These amounts 
increased  from  the  fiscal  2011  grant  levels  as  a  result  of  adjustments  for  market  competitiveness.    In 
addition,  as  mentioned  above,  in  fiscal  2012,  the  Committee  focused  on  increasing  incentive  award 
opportunities for our executive officers as a portion of total potential compensation, rather than approving 
larger  base  salary  increases,  in  order  to  more  strongly  link  executive  compensation  with  Company 
performance and shareholder returns.  

Equity  awards  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. 

30 

 
 
 
 
 
 
 
 
 
 
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 grants of RSUs to executive officers in fiscal 2012.  In fiscal 2009, the Committee made 
retention-related  grants  of  RSUs  to  all  executive  officers  other  than  Mr.  Foate,  which  vested  in  August 
2012.  The Committee believes that these grants had their intended retention effect. 

2012 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  2012,  the 
Committee made total grants of options and RSUs to the named executive officers as follows:

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

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  executive  officers  are  in  compliance  with  the  procedural  requirements  of  the  guidelines,  while  seven  of  our 
executive officers, including our CEO, have met the ultimate ownership amounts required by the guidelines.

Clawback  Policy.    Pursuant  to  the  Plexus  Corp.  Executive  Compensation  Clawback  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 

31 

 
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.  The Company’s Insider Trading Policy explicitly prohibits 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.  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  $10,000  per 
calendar year.  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 

32 

 
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 2012 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) 9%  of  the  executive’s  total  targeted  cash 
compensation,  minus  Plexus’  permitted  contributions  to  the  executive  officer’s  account  in  the 
401(k) Plan, or (b) $13,500.  Total targeted cash compensation is defined as base salary plus the 
targeted annual incentive plan 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,  after  reviewing  the  results  of  a 
competitive  analysis  performed  by  Towers  Watson,  the  Committee  increased  the  Company 
contribution to its current level in order to be more in line with current market practice.

Employer Contributions.  For fiscal 2012, the total employer contributions to the SERP accounts 
was $395,840 for all participants as a group, including $139,315 for the CEO.  See footnote 4 to 
the “Summary Compensation Table.”

Special Contribution.  The SERP also allows the Committee to make discretionary contributions 
over and above the annual contribution noted above.  In fiscal 2012, the Committee did not make 
any such contributions to any of the executive officers, including the named executive officers.    

–

–

Fiscal 2013 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 2012 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 

33 

 
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 reviews the benefit levels under these agreements 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 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 3.7% 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’ 

34 

 
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 time vested RSUs) 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, as was the case in fiscal 2012. 

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. 

COMPENSATION COMMITTEE REPORT 

The duties and responsibilities of the Compensation and Leadership Development Committee of the board 
of  directors  are  set  forth  in  a  written  charter  adopted  by  the  board,  as  set  forth  on  the  Company’s  website  as 
described above under “Corporate Governance—Board Committees—Compensation and Leadership Development 
Committee.”    The  Committee  reviews  and  reassesses  this  charter  annually  and  recommends  any  changes  to  the 
board for approval.  

As part of the exercise of its duties, the Committee has reviewed and discussed with management the above 
“Compensation  Discussion  and  Analysis”  contained  in  this  proxy  statement.    Based  upon  that  review  and  those 
discussions, the Committee recommended to the board of directors that the Compensation Discussion and Analysis 
be  incorporated  by  reference  in  Plexus’  annual  report  to  shareholders  on  Form  10-K  and  included  in  this  proxy 
statement.

(1)  Includes  amounts  voluntarily  deferred  by  the  named  persons  under  the  Plexus  Corp.  401(k)  Retirement  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 2012, fiscal 2011 and fiscal 2010, 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, it is in the 
“Bonus” column.  To the extent that the cash incentive resulted from corporate financial performance, and, for 
fiscal  2012  and  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 “2012” row were earned in fiscal 2012 but 
will be paid in fiscal 2013, the amounts shown in the “2011” row were earned in fiscal 2011 and were paid in 
fiscal 2012, and the amounts shown in the “2010” row were earned in fiscal 2010 and were paid in fiscal 2011.  
The amounts in the “Non-Equity Incentive Plan Compensation” column for fiscal 2010 also include the value 

36 

 
of  long-term  cash  awards  granted  in  that  year,  which  vest  on  the  third  anniversary  of  their  respective  grant 
dates; no equivalent grants were made for fiscal 2012 or fiscal 2011. 

(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 2012, fiscal 2011 and fiscal 
2010  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  that  we  used  to 
determine  the  valuation  of  the  awards  are  discussed  in  footnote  10  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  2012,  and  the  “Outstanding  Equity  Awards  at  Fiscal  Year  End”  table  below 
relating to all outstanding stock and option awards at the end of fiscal 2012. 

(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. Lim 

Under  the  executive  flexible  perquisite  benefit,  executive  officers  may  be  reimbursed  for  expenses  up  to 
$15,000 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.  This benefit is not 
grossed  up  for  taxes.  The  amounts  in  the  “Executive  Flexible  Perquisite  Benefit”  column  above  include  the 
reimbursements under that program in the fiscal years listed; these amounts may exceed the calendar year limits 
due to 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.

GRANTS OF PLAN-BASED AWARDS 
2012 

The following table sets forth information about stock and option awards that were granted to the named 
executive officers in fiscal 2012 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  2012  performance  (to  be  paid  in  fiscal  2013)  under  the  VICP.    As  a  result  of  fiscal  2012 
corporate  performance,  cash  incentive  awards  based  on  these  criteria  were  earned  in  2012,  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

*  Represents  a  potential  cash  incentive  payment  for  fiscal  2012  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  2012,  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.  Pursuant to 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 2012 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  23,  2015,  assuming  continued  employment.  See  the  discussions  below  under  the 

caption “2008 Long-Term Plan.” 

VICP

The VICP (as it applies to our executive officers) is 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  2012  was  below  the  threshold  level  for  revenue  and  between  the 
target and maximum payout levels for return on capital employed (“ROCE”); therefore, total cash incentives based 
on  corporate  financial  goals  (which,  for  fiscal  2012,  were  only  paid  based  on  ROCE  performance)  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 $171,692 for Mr. Foate 
(which would have been 20% of his cash incentive award at the targeted levels) and varied from $41,578 to $52,177 
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.    As  a  result  of the  volatility  of  the  stock  market  in  recent 
years,  particularly  for  Plexus  stock,  the  Committee  makes,  and  anticipates  continuing  to  make,  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  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 2012, annual grants were made in 
January 2012, 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.

NONQUALIFIED DEFERRED COMPENSATION 
2012 

Plexus  does  not  maintain  any  defined  benefit  pension  plans.    Plexus’  only  retirement  savings  plans  are 
defined  contribution  plans:  the  401(k)  Plan  for  all  qualifying  U.S.  employees;  and  the  supplemental  executive 
retirement plan (the “SERP”) for executive officers (other than Mr. Lim, as described below).  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 
Internal Revenue Code (the “Code”) mandated limit of $17,000 ($22,500 if age 50 or older) in calendar year 2012; 
Plexus will match 100% of the first 4.0% of salary which an employee defers, 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 2012 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  2012.    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,  the 
discretionary contribution is the greater of (a) 9% of the executive’s total targeted cash compensation, minus Plexus’ 
permitted contributions to the executive officer’s account in the 401(k) Plan, or (b) $13,500.  The Committee may 
also choose to make additional or special contributions; no such contributions were made in fiscal 2012. 

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 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 September 29, 2012.  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 September 29, 2012 (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 September 29, 2012, 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 2012 and the target 
VICP  cash  incentive  payment  for  2012.    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.    Certain  outstanding  unvested  stock  options  had  no  immediately 
realizable  value  because  the  respective  exercise  prices  were  higher  than  $30.29,  the  closing  price  of  Plexus’ 
common stock on September 28, 2012, the last trading day of fiscal 2012.  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 $30.29 per share on September 28, 2012, the last 
trading date of fiscal 2012.  Grants of long-term cash awards were discontinued after fiscal 2010 in order to align 
all long-term incentives with the Company’s overall performance and the interests of shareholders. 

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  September  29,  2012,  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 2012, 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 2012. 

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 

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 September 29, 2012, 
with Plexus management; 
discussed  with  PricewaterhouseCoopers  LLP,  Plexus’  independent  auditors,  those  matters  which  are  
required  to  be  discussed  by  Statement  on  Auditing  Standards  No.  61,  “Communication  with  Audit 
Committees,”  as  amended  (AICPA,  Professional  Standards,  Vol.  1,  AU  section  380),  and  SEC 
Regulation S-X, Rule 2-07 “Communication with Audit Committees”; and 
received  the  written  disclosure  and  the  letter  from  PricewaterhouseCoopers  LLP  required  by  the 
applicable  standards  of  the  Public  Company  Accounting  Oversight  Board  regarding  the  independent 
accountant’s communications with the Audit Committee concerning independence, and has discussed 
with PricewaterhouseCoopers LLP its independence. 

Based  on  the  foregoing,  the  Audit  Committee  recommended  to  the  board  of  directors  that  the  audited 
financial  statements  be  included  in  Plexus’  annual  report  on  Form  10-K  for  the  fiscal  year  ended  September  29, 
2012.  The Audit Committee further confirmed the independence of PricewaterhouseCoopers LLP. 

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

Peter Kelly 

AUDITORS 

Stephen P. Cortinovis 
Mary A. Winston

Subject  to  ratification  by  shareholders,  the  Audit  Committee  intends  to  reappoint  the  firm  of 
PricewaterhouseCoopers  LLP  as  independent  auditors  to  audit  the  financial  statements  of  Plexus  for  fiscal  2013.  
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 2012 and 2011 were as follows: 

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

      2012  

      2011

  $1,105,890 
          --   
         44,575 
          --   

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

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 2012 or 2011 that were not approved in advance by the 
Audit Committee under this policy.

“SAFE HARBOR” CAUTIONARY STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM 
ACT OF 1995: 

The  statements  contained  in  this  Form  10-K  which  are  guidance  or  which  are  not  historical  facts  (such  as  statements  in  the 
future  tense  and  statements  including  believe,  expect,  intend,  plan,  anticipate,  goal,  target  and  similar  terms  and  concepts), 
including  all  discussions  of  periods  which  are  not  yet  completed,  are  forward-looking  statements  that  involve  risks  and 
uncertainties. These risks and uncertainties include, but are not limited to: the risk of customer delays, changes, cancellations or 
forecast  inaccuracies  in  both  ongoing  and  new programs;  the  poor  visibility  of  future  orders,  particularly  in  view  of  current 
economic  conditions;  the  effects  on  Plexus  of  Juniper  Network's  intended  disengagement;  the  economic  performance  of  the 
industries,  sectors  and  customers  we  serve;  the  effects  of  the  volume  of  revenue  from  certain  sectors  or  programs  on  our 
margins in particular periods; the risk that our agreement with Kontron does not result in the revenues or margins anticipated 
by  us;  our  ability  to  secure  new  customers,  maintain  our  current  customer  base  and  deliver  product  on  a  timely  basis;  the 
particular risks relative to new or recent customers or programs, which risks include customer and other delays, start-up costs, 
potential  inability  to  execute,  the  establishment  of  appropriate  terms  of  agreements,  and  the  lack  of  a  track  record  of  order 
volume  and  timing;  the  risks  of  concentration  of  work  for  certain  customers;  our  ability  to  manage  successfully  a  complex 
business model characterized by high customer and product  mix, low volumes and demanding quality, regulatory, and other 
requirements; the risk that new program wins and/or customer demand may not result in the expected revenue or profitability; 
the  fact  that  customer  orders  may  not  lead  to  long-term  relationships;  the  effects  of  shortages  and  delays  in  obtaining 
components  as  a  result  of  economic  cycles  or  natural  disasters;  the  risks  associated  with  excess  and  obsolete  inventory, 
including  the  risk  that  inventory  purchased  on  behalf  of  our  customers  may  not  be  consumed  or  otherwise  paid  for  by  the 
customer, resulting in an inventory write-off; the weakness of areas of the global economy and the continuing instability of the 
global  financial  markets  and  banking  system,  including  the  potential  inability  of  our  customers  or  suppliers  to  access  credit 
facilities;  the  effect  of  changes  in  the  pricing  and  margins  of  products;  the  effect  of  start-up  costs  of  new  programs  and 
facilities,  such  as  our  announced plans  to  replace  facilities  in  Romania  and  the United  States,  and other  recent,  planned  and 
potential  future  expansions;  increasing  regulatory  and  compliance  requirements;  possible  unexpected  costs  and  operating 
disruption in transitioning programs; raw materials and component cost fluctuations; the potential effect of fluctuations in the 
value of the currencies in which we transact business; the potential effects of regional results on our taxes and ability to use 
deferred tax assets; the potential effect of world or local events or other events outside our control (such as drug cartel-related 
violence in Mexico, changes in oil prices, terrorism and weather events); the impact of increased competition; and other risks 
detailed below in “Risk Factors”, otherwise herein, and in our Securities and Exchange Commission filings. 

In addition, see Risk Factors in Part I, Item 1A and Management's Discussion and Analysis of Financial Condition and Results 
of Operations in Part II, Item 7 for a further discussion of some of the factors that could affect future results.

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 solutions to our customers through our unique Product Realization Value 
Stream.   Our  customer-focused  solutions  model  seamlessly  integrates  innovative  product  conceptualization,  design, 
commercialization, manufacturing, fulfillment and sustaining solutions. Plexus delivers comprehensive end-to-end solutions for 
customers in the Americas (“AMER”), Europe, Middle East, and Africa (“EMEA”) and Asia-Pacific (“APAC”) regions.   

We provide award-winning customer service to more than 140 branded product companies in the Networking/Communications, 
Healthcare/Life Sciences (formerly known as Medical), Industrial/Commercial and Defense/Security/Aerospace market sectors.  
Beginning in fiscal 2013, we renamed our Medical market sector as the Healthcare/Life Sciences market sector.  This change 
stems from our evolving strategy and enhanced capabilities within this market and reflects the industry's progression to holistic 
patient care.  We believe Healthcare/Life Sciences more accurately defines this growing industry and aligns with our existing 
and targeted customer base.    

Our  customers  have  stringent  quality,  reliability  and  regulatory  requirements,  mandating  exceptional  production  and  supply 
chain agility. Their products require complex configuration management, direct order fulfillment (to end customers) and global 
logistics  management  and  sustaining  solutions.  To  service  the  complexities  our  customers'  products  demand,  we  utilize  our 
Product Realization Value Stream, addressing our customers' products from concept to end of life—conceptualization, design, 
commercialization, manufacturing, fulfillment and sustaining solutions.  

Plexus  is  passionate  about  striving  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.    To 
support  and  deliver  on  our  strategy,  we  align  our  operations,  processes,  workforce  and  financial  metrics  through  a 
multidimensional business strategy that includes:  

(cid:129)  A high performance, accountable organization with a highly skilled and talented workforce that strives to provide 

customer service excellence 

(cid:129)  A customer driven, disciplined deployment of strategic growth through sector based go-to-market strategies 
(cid:129)  Execution  through  continuous  evaluation  and  optimization  of  our  business  processes,  supporting  our  return  on 

invested capital (“ROIC”) goal 

We operate flexible manufacturing facilities and processes designed to accommodate customers with multiple product lines and 
configurations.  Each of our customers is supported by a multi-disciplinary customer team. One or more uniquely configured 
“focus factories,” supported by a supply chain and logistics solution, are designed to meet the flexibility and responsiveness to 
support customer fulfillment requirements. 

Our go-to-market strategy is tailored by business development and customer management teams dedicated to each of the four 
sectors we serve. These teams execute our sector strategies through expertise in advancements within markets and technology 
as well as unique quality and regulatory capabilities. Our sector teams help define Plexus' strategy for growth with a particular 
focus on expanding the value-added solutions we offer customers.  

Our financial model aligns with our business strategy. Our primary focus is 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;  at  the  end  of  fiscal  2012  we  reduced  our  estimated  WACC  from  12.5%  to  12.0%  for  fiscal  2013.    We  believe 
economic  profit  is  a  fundamental  driver  of  shareholder  value.    Plexus  measures  economic  profit  by  taking  the  difference 
between ROIC and WACC and multiplying it by invested capital.  By exercising discipline to generate an ROIC in excess of 
our WACC, with focus on economic profit, our goal is to ensure that Plexus creates value for our shareholders.   

Relative to our competition, overriding factors such as lower manufacturing volumes, flexibility and fulfillment requirements, 
as well as complex regulatory environments, typically result in higher investments in inventory and selling and administrative 
costs. The cost variance from our competitors is especially evident relative to those that provide EMS services for high-volume, 
less complex products, with less stringent requirements (e.g., consumer electronics).

Plexus serves a diverse customer landscape that includes industry-leading, branded product companies, along with many other 
technology pioneering start-ups or emerging companies that may or may not maintain manufacturing capabilities.  As a result 
of  serving  market  sectors  that  rely  on  advanced  electronics  technology,  our  business  is  influenced  by  critical  technological 
trends such as the level and rate of development of wired and wireless telecommunications infrastructure, communications data 
and data  bandwidth growth,  and Internet usage.   In  addition  to prime  technology  advancements,  key  government  and policy 
trends  impact  our  business,  including  the  U.S.  Food  and  Drug  Administration's  (“FDA”)  approval  of  new  medical  devices, 
defense  procurement  practices,  and  other  government  and  regulatory  processes.    Plexus  may  benefit  from  increasing 
outsourcing trends. 

We  provide  most  of  our  optimized  solutions  on  a  turnkey  basis,  and  we  procure  some  or  all  materials  required  for  product 
assembly.    We  provide  select  services  on  a  consignment  basis,  meaning  the  customer  supplies  the  necessary  materials  and 
Plexus  provides  the  labor  and  other  services  required  for  product  assembly.    In  addition  to  manufacturing,  turnkey  services 
require material procurement and warehousing 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 9,600 full-time employees, including approximately 
1,850 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  25  active  facilities  in  16  locations,  totaling 
approximately 3.0 million square feet. Plexus' facilities are strategically located to support the global supply chain, as well as 
manufacturing and engineering needs of customers in our targeted market sectors. 

Plexus maintains a website at www.plexus.com. As soon as is reasonably practical, and after we electronically file or furnish all 
filings to the Securities and Exchange Commission (“SEC”), we provide online copies, free of charge. These reports include: 
Annual  Reports  on  Form  10-K,  Quarterly  Reports  on  Form  10-Q,  Current  Reports  on  Form  8-K,  and  amendments  to  those 
reports.  Our Code of Conduct and Business Ethics is also posted on our website. You may access these SEC reports and the

Solutions 

As  an  integrated,  fully  accountable  partner,  we  deliver  optimized  product  realization  solutions  that  carry  our  customers' 
products  from  concept  to  end  of  life.    Tailoring  our  Product  Realization  Value  Stream  to  each  product  and  program,  Plexus 
provides unique solutions designed to meet the needs of each of our customers.  As our partnerships grow and mature, we aim 
to engage our customers in full utilization of our Product Realization Value Stream. 

Conceptualize.  During  the  product  development  and  conceptualization  phases,  new  product  ideas  are  created  and  evaluated 
with  both  the  customer's  and  Plexus'  engineering  teams.    We  closely  collaborate  with  our  customers  to  capture  their  new 
product vision and clarify requirements. Our industrial design team attempts to analyze a product through the end user's eyes 
focusing  on  ergonomics,  use  case  research,  user  interface,  aesthetics  and  evaluation  mockups.  Upon  completion  of  concept 
evaluations,  the  Plexus  team  prototypes  what  it  believes  to  be  the  most  promising  designs,  working  concurrently  with 
engineering, manufacturing and supply chain teams. Future phases ensure design intent is maintained, while realizing the final 
product solution. 

Design.  Plexus  invests  in  the  latest  technology,  design  and  automation  tools  to  provide  comprehensive  design  and  value-
engineering solutions. Product design includes, but is not limited to, the following solutions: 

Program management

Plexus also provides comprehensive value-engineering solutions, extending the product life cycle. Our value-add solutions span 
a wide range—engineering change-order management, cost reduction redesign, component obsolescence management, product 
feature expansion, test enhancement and component re-sourcing. 

Commercialize. Of all the phases in our Product Realization Value Stream, the commercialize phase carries the most influence 
with respect to converting ideas into viable products. Commercialization starts early in the design phase and extends through 
manufacturing  transition,  often  in  tandem  with  Design  for  Excellence  (“DFX”).    Our  DFX  solutions  encompass  a  wide 
collection  of  specific  design  solutions  including  design  for  test,  design  for  manufacturability/assembly  and  design  for 
fabrication.    The  goal  of  DFX  is  to  facilitate  an  efficient  transition  from  engineering  to  manufacturing.    The  commercialize 
phase  also  includes  prototyping,  new  product  introduction,  design  for  supply  chain,  test  development  and  transition 
management.  We believe our commercialization solutions provide significant value by accelerating time-to-market, reducing 
change activity and providing customers with a robust and enduring product. 

Manufacture. Plexus applies an optimized manufacturing approach, not a one-size-fits-all model. Our scalable manufacturing 
solutions  integrate  flexibility  for  our  customers  through  tailored  supply  chain  solutions.  Our  focus-factory  model  provides  a 
dedicated  team  designed  to  drive  success  while  saving  time  and  money.  Focus-factories  place  the  customer  at  the  center  of 
operations, executing within a culture of continuous improvement. Plexus exclusively focuses on mid-to-low volume, higher-
complexity  programs  that  range  from  lower-level  assemblies  to  finished  electro-mechanical  products.  Our  manufactured 
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 

(cid:129) 
(cid:129)  Basic assembly - a sub-assembly that includes PCBs and other components 
(cid:129) 

System integration - a finished product or sub-system assembly that includes more complex components such as 
PCBs, basic assemblies, custom engineered components, displays, optics, metering and measurement or thermal 
management 

(cid:129)  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  and  mechatronic  integration  products  run  larger  in  size  than  other  assemblies;  the  products  range  from  kiosks  to 
finished healthcare devices and life sciences equipment to other complex electro-mechanical assemblies. These products often 
combine other integrated solutions we provide and may require further unique facility configurations or supply chain solutions.  

Fulfill. Plexus offers fulfillment and logistics solutions to all our customers in the forms of Direct Order Fulfillment (“DOF”), 
Build  to  Order  (“BTO”)  and Configure  to Order  (“CTO”).  Plexus  receives  DOF  orders  from  our  customers  that  provide  the 
final specifications required by their end customer.  Through BTO and CTO, Plexus delivers the product directly to the end 
customer.  The DOF process relies on Enterprise Resource Planning (“ERP”) systems integrating the overall supply chain, from 
parts procurement through manufacturing and logistics. 

Sustain. Plexus provides our customers with a range of solutions support after product launch including sustaining engineering, 
supply chain, and manufacturing solutions.  In support of certain customers, we may provide these tailored sustaining solutions 
for products that we may not have originally manufactured:  

Failure and root cause analysis

have  capabilities  to  assemble  finished  medical  devices  meeting  FDA  Quality  Systems  Regulation  requirements,  and  similar 
regulatory requirements in other countries. 

Our  manufacturing  and  engineering  facilities  are  certified  to  the  most  current  revision  of  the  ISO  9001  standard.    We  have 
additional certifications and/or registrations held by certain facilities in the following regions:

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 2012, we served approximately 140 customers. We offer advanced design and production 
capabilities, allowing our customers to concentrate on their core competencies.  Plexus helps accelerate our customers' time to 
market, reduce their investment in engineering and manufacturing capacity, and optimize total product cost.   

Juniper Networks, Inc. (“Juniper”) accounted for 16 percent of our net sales in fiscal 2012, 17 percent in fiscal 2011 and 16 
percent in fiscal 2010. No other customer accounted for 10 percent or more of our net sales in fiscal 2012, 2011 or 2010. The 
loss of any of our major customers could have a significant negative impact on our financial results. 

On  November  5,  2012,  Juniper,  the  Company's  largest  customer,  notified  the  Company  that  it  will  disengage  from  Plexus.  
Sales to Juniper are primarily made from the Company's AMER and APAC segments.  The specific timing of the transition of 
the Juniper business from Plexus is not known at this time, although it is currently expected to occur by the end of fiscal 2013. 
 The Company is currently evaluating the financial, operational and other impacts of the disengagement. 

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  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. 

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 independent of 
sales to others.    

The distribution of our net sales by market sectors for fiscal 2012, 2011 and 2010 is shown in the following table:

Although  our  current  business  development  focus  is  based  on  our  targeted  market  sectors,  we  evaluate  our  financial 
performance and allocate our resources geographically (see Note 12 in Notes to Consolidated Financial Statements regarding 
our reportable segments).  Plexus offers a uniform array of services for customers in each market sector and we do not dedicate 
operational  equipment,  personnel, facilities  or other resources  to particular  market  sectors,  nor  internally  track  our costs  and 
resources per market sector. 

Materials and Suppliers 

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

We  may  also  purchase  non-electronic  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 components range 
from standard to highly customized and vary widely in terms of market availability and price.  

Component  shortages  and  subsequent  allocations  by  suppliers  are  an  inherent  risk  to  the  electronics  industry,  and  have 
particularly been an issue for us and the industry in recent years.  We discuss the causes of these shortages 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.   

The Plexus global supply chain management organization attempts to create strong supplier alliances and ensure a steady flow 
of components and products at competitive prices.  Our global expediting and escalation processes track and analyze supply 
chain  health  and  anticipate  constraints.  Plexus  can  often  influence  the  selection  of  new  product  components  throughout  the 
design phase of the Product Realization Value Stream.  The advanced supply chain solutions we develop in partnership with 
our customers improve the continuity of supply and supply chain flexibility.  

New Business Development 

Our new business development is organized around our targeted market sectors.  Each market sector has a team of dedicated 
resources.  A market development vice president and customer management vice president oversee and provide direct or matrix 
leadership to business development directors, customer directors, customer managers, business development, supply chain and 
manufacturing  subject  matter  experts,  and  market  sector  analysts.    Our  sales  and  marketing  efforts  focus  on  targeting  new 
customers and expanding business with existing customers.  We believe our ability to provide a full range of product realization 
services  gives  Plexus  a  marketing  advantage;  our  sector  teams  participate  in  marketing  through  direct  customer  contact  and 
participation in industry events and seminars. 

Competition 

Plexus operates in a highly competitive market, with a goal to be best-in-class at meeting the unique needs of our customers.  
We provide flexible solutions, timely order fulfillment, and strong engineering, testing and production capabilities.  A number 
of  competitors  may  provide  electronics  manufacturing  and  engineering  services  similar  to  Plexus.  Others  may  be  more 
established  in  certain  industry  sectors,  or  have  greater  financial,  manufacturing  or  marketing  resources.  Smaller  competitors 
compete  mainly  in  specific  sectors  and  within  limited  geographical  areas.    Plexus  occasionally  competes  with  in-house 
capabilities  of  current  and  potential  customers.  Plexus  maintains  strong  awareness  and  knowledge  of  our  competitors' 
capabilities, in order to remain highly competitive within the broad scope of the EMS industry. 

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, warehouse management and shop floor control systems serve all of our manufacturing sites, providing a 
core  set  of  consistent,  global  business  applications.    This  consistency  augments  our  other  management  information  systems, 
allowing  us  to  standardize  our  ability  to  translate  data  from  multiple  production  facilities  into  operational  and  financial 
information.    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. 

Social Responsibility 

We are committed to social responsibility within all our business and operations practices. Our strategies, objectives and targets 
exemplify  thoughtful  concern  in  the  areas  of  human  rights,  labor  practices,  the  environment,  worker  health  and  safety,  fair 
operating practices and the social impact of the organization in the communities where we operate.  Our approach to ensuring 
socially  responsible  business  practices  is  based  on  the  concepts  contained  within  the  International  Organization  for 
Standardization's “Guidance on Social Responsibility” (ISO 26000), input from the Electronics Industry Citizenship Coalition 
(EICC) and local and federal legal requirements. 

In order to uphold our reputation and continue to be a responsible and engaged community member, it is imperative that Plexus 
employees and our business partners follow the highest standards of ethical behavior and personal integrity. Our Employee and 
Supplier Codes of Conduct and Business Ethics represent a foundation for these principles; employees and business partners 
worldwide are expected to adopt and practice their standards. 

Plexus works to provide a better planet for tomorrow through environmental sustainability efforts. While providing what we 
believe  are  best-in-class,  high-quality  product  realization  solutions  for  the  electronics  industry,  we  continue  to  focus  on 
minimizing  our  impact  on  the  world  around  us.  Our  manufacturing  operations  are  100%  certified  under  ISO  14001.  We 
maintain  Company-wide  reduction  targets  for  both  carbon  emissions  and  waste  generation.  We  strive  to  comply  with  all 
federal, state and foreign environmental laws and do not anticipate any significant expenditure 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 development opportunities 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 9,600 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  228  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 China, Germany, Malaysia, Mexico, Romania and the United States 
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 generally positive and stable.

RISK FACTORS 

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

Our quarterly and annual results may vary significantly depending on various factors, many of which are beyond our control. 
These factors include:

(cid:129) 

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, as well as the volatility of these changes 
variations in sales and margins among geographic regions 
varying gross margins among different programs, including as a result of pricing concessions to certain customers 
failures of our customers to pay amounts due to us 
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 
exchange rates 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 60 percent of our net sales for the fiscal year ended September 29, 2012, and 55 percent of our net 
sales for the fiscal year ended October 1, 2011. For each of the fiscal years ended September 29, 2012 and 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, particularly given 
the volatile nature of certain programs.  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.  On November 5, 2012, our largest customer, Juniper, notified us that it will disengage with 
Plexus.    The  specific  timing  of  the  transition  of  the  Juniper  business  from  Plexus  is  not  known  at  this  time,  although  it  is 
currently expected to occur by the end of fiscal 2013.  We are currently evaluating the financial, operational and other impacts 
of the disengagement. 

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,  business  and/or  regulatory  conditions  that 
affect  the  sector,  or  our  failure  to  choose  appropriate  sectors  can  particularly  impact  Plexus.  For  instance,  sales  in  the 
Healthcare/Life  Sciences  sector  are  substantially  affected  by  trends  in  the  healthcare  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,  including  as  a  result  of  the  Patient  Protection  and  Affordable  Care  Act  (the  "Affordable  Care  Act").  
Further, potential reductions in U.S. defense spending, including those due to sequestration if the Budget Control Act of 2011 
goes into effect on January 1, 2013, 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. 

From  time  to  time,  our  customers,  including  formerly  significant  customers,  have  been  affected  by  merger  and  acquisition 
activity.  While these transactions may present Plexus with opportunities to capture new business, they also create the risk that 
these customers will partially or completely disengage as a result of transitioning such business to other contract manufacturers 
or deciding to manufacture the products internally.  

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

Global financial markets have been, and continue to be, unstable and unpredictable. Worldwide economic conditions have been 
weak and may deteriorate further. For example, substantial financial and credit issues have arisen in the European Union as a 

10 

 
 
 
 
 
result of the sovereign debt crisis, currency instability and other factors affecting economies worldwide. The instability of the 
markets  and  areas  of  weakness  in  the  global  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, 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  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. 

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 
changes in labor markets, such as government mandated wage increases, and difficulties in appropriately staffing and 
managing personnel in multiple cultures 
compliance  with  laws,  such  as  the  U.S.  Foreign  Corrupt  Practices  Act  and  the  U.K.  Bribery  Act,  applicable  to 
companies with global operations 
significant natural disasters and other events or factors impacting local infrastructure 
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  appropriately  address  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,  as  well  as  government  imposed  restrictions  on  producing 
certain products  in,  or  shipping  them  to,  specific  countries.  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 in both design and production. 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 engineering or other service 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. 

11 

 
 
  
 
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. 

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  for  multiple  programs  of  varying  sizes  simultaneously,  including  in 
multiple locations.  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 result in claims against us and/or 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  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; in addition, as a result of production startup costs, new programs 
are inherently less efficient in their earlier phases than mature programs. 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 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 materials or components. While we attempt to cancel, return or otherwise mitigate excess and 
obsolete inventory and require customers to reimburse us for these items, we may not actually be reimbursed timely or be able 
to collect on these obligations.  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  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 

12 

 
 
 
 
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.  During  fiscal  2012,  we  opened  a  new 
manufacturing  facility  in  Malaysia  (Penang),  entered  into  a  strategic  arrangement  with  Kontron  and  further  expanded  our 
employment in Germany (Darmstadt).  We expect to open a new manufacturing facility in China (Xiamen) in the first half of 
fiscal 2013.  In addition, in the second half of fiscal 2012, construction began on a facility in Romania (Oradea) to replace a 
leased facility and on a new manufacturing facility in the U.S. (Neenah, Wisconsin) to replace two existing leased facilities.  
We anticipate that both of these facilities will open in the second half of fiscal 2013.  If we are unable to effectively manage our 
currently anticipated growth, or related anticipated net sales are not realized, our operating results could be adversely affected. 
In addition, we may expand our operations in new geographical areas where currently we do not operate. Other risks of current 
or future expansion include:

(cid:129) 

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 excess capacity or higher levels of employment entail short-term costs, reductions in 
capacity 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, particularly when the production requirements of certain products is site-specific, or 
to achieve increased efficiencies, we sometimes require additional capacity in one location while reducing capacity in another.  
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. 

Changes  in  tax  laws,  potential  tax  disputes,  negative  or  unforeseen  tax  consequences  and/or  further  developments 
affecting our deferred tax assets 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 expiration of the tax holiday in China is not expected to have a material impact on 
the  effective  tax  rate.    However,  the  Company  cannot  provide  assurances  as  to  the  effect  and  will  continue  to  monitor  the 
projected impact.   

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.    In  addition,  other  recently  adopted  or  potential  changes  to  tax  laws  in  the  other  jurisdictions  in  which  we 
operate could also affect our results.     

13 

 
 
  
 
 
Plexus  is  eligible  for  up  to  $15  million  in  Wisconsin  state  tax  credits  in  connection  with  the  construction  of  our  new 
manufacturing facility in Neenah, if we meet certain requirements related to, among other matters, job creation and retention, 
employee training and capital investment.  If we do not comply with these requirements, we may not be able to realize all, or 
any,  of  these  tax  credits.    As  of  September 29,  2012,  approximately  $1.0  million  has  been  recognized  as  a  miscellaneous 
receivable related to the credits.   

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. In 
the  fourth  quarter  of  fiscal  2012,  as  a  result  of  a  reduction  in  forecasted  near  term  profitability  in  the  AMER  region,  we 
established  a  valuation  allowance  resulting  in  an  additional  tax  provision  of  approximately  $22.8  million,  with  an  offset  to 
other comprehensive income of $2.2 million, for a net deferred tax asset reduction of $20.6 million.  Adverse changes in the 
profitability  and  financial  outlook  in  the  U.S.  or  foreign  jurisdictions  may  require  the  creation  of  an  additional  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,  customer-driven  and  industry 
standards and third party certification requirements. 

We are subject to extensive government regulation and industry standards relating to the products we design and manufacture 
as well as how we conduct our business. These regulations and standards affect the sectors we serve and every aspect of our, 
and our customers’, business, including our labor, employment, workplace safety, environmental, sourcing 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, as well as customer-driven and industry standards, could 
seriously affect our operations, customer relationships, reputation and profitability. 

Our Healthcare/Life Sciences sector 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, including as a result of the Affordable Care Act, and how medical devices are taxed, could affect the willingness 
and ability of end customers to purchase the products of our customers in this sector as well as impact our margins. 

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 countries.  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.  Failure  to  comply  with  related  requirements  and  regulations,  including  the 
International Traffic in Arms Regulation, the Export Administration Regulation, the Foreign Assets Control Regulation and the 
Federal Acquisition 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 Networking/Communications sector 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 those resulting from the Sarbanes-Oxley Act and the Dodd-Frank Wall Street Reform and Consumer 

14 

 
Protection  Act,  affecting,  among  other  areas,  our  accounting,  internal  controls,  corporate  governance  practices,  securities 
disclosures  and  reporting;  for  instance,  the  SEC  recently  adopted  disclosure  requirements  related  to  the  use  of  specified 
minerals ("conflict minerals") that are necessary to the functionality or production of products manufactured, or contracted to 
be  manufactured  by  publicly-held  companies.  Our  failure  to  comply  with  these  requirements  could  materially  affect  our 
reputation, 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. 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 and/or fines to us as well as affect our reputation. 

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,  industry  standards  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. 

In addition to government regulations and industry standards, our customers may require us to comply with their own social 
responsibility or other business policies or standards, which may be more restrictive than current laws and regulations as well 
as our pre-existing policies, before they commence, or continue, doing business with us.  Our compliance with these procedures 
or standards could be costly, and our failure to comply could result in the loss of business with such customers, damage to our 
reputation and/or have a material adverse affect on our business, financial condition and results of operations. 

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 

(cid:129) 
(cid:129)  maintain and enhance our technological capabilities 
(cid:129) 
(cid:129) 
(cid:129) 
(cid:129) 

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 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,  and  our  need  to  maintain  our 
personnel and other resources during times of fluctuating demand,  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,  privacy, 
reliability, compliance, 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 

15 

 
 
  
 
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. 

In  the  current environment,  our revenue  growth has been  heavily  biased  toward ramping new program  wins  as  compared  to 
end-market growth of mature programs.  The management of resources in connection with the establishment of new or recent 
programs  and  customer  relationships,  as  well  as  program  transfers  between  facilities,  and  the  need  to  estimate  required 
resources in advance of production can adversely affect our gross and operating margins and level of working capital. 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 production efficiencies in the early stages.  We are managing a number of new programs at 
any  given  time;  therefore,  we  are  exposed  to  these  factors  in  varying  magnitudes.  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 meet customer needs, seek long-term efficiencies or respond 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. 

While these factors tend to affect new, recent or transferred programs, they can also impact more mature, or maturing programs 
and customer relationships, especially programs where end-market demand can be somewhat volatile. 

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

We do not have any long-term supply agreements.  At various times, including fiscal 2012, we have experienced raw material 
and  component  shortages  due  to  supplier  capacity  constraints  or  their  failure  to  deliver.    Periodic  shortages  are  expected  to 
occur  in  the  future.    Such  constraints  can  also  be  caused  by  world  events,  such  as  government  policies,  terrorism,  armed 
conflict, natural disasters, economic recession and other localized events.  We rely on a limited number of suppliers for many 
of the raw materials and components 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.  Such suppliers may encounter quality problems, labor disputes, 
financial difficulties or business continuity issues that could preclude them from delivering raw materials or components 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  components  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  materials  and  components  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 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 prices and 
other  factors,  we  may  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, as a result of our pricing strategies 
and practices, raw material and component 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. 

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, and produce 
products for industries, such as health care, defense and aerospace, that tend to have higher risk profiles. Despite our quality 
control  and  quality  assurance  efforts,  problems  may  occur,  or  may  be  alleged,  in  the  design  and/or  manufacturing  of  these 
products, including as a result of business continuity issues.  Whether or not we are responsible, problems in the products we 
manufacture, whether real or alleged, whether caused by faulty customer specifications, the design or manufacturing processes 

16 

 
 
 
or  a  component  defect,  may  result  in  delayed  shipments  to  customers  and/or  reduced  or  canceled  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 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: 

(cid:129) 

(cid:129) 
(cid:129) 

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 economic challenges affecting the industry and 
the economy as a whole. 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, including the inability to hire and retain sufficient personnel, may harm our business. 

Our success depends in large part on the continued services of our key technical and management personnel, and on our ability 
to attract, 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. 

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, including internationally, we need to attract 
and 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,  wage  pressure  and  changing  wage 
requirements, increasing health care costs, differing employment laws and regulations in various countries, local competition 
for  employees  as  well  as  high  turnover,  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. 

We  have  increased  our  borrowings  in  recent  years.    However,  we  cannot  be  certain  that  our  existing  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,  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.  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. 

18 

 
 
 
 
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,  as  well  as  strategic  arrangements, and  may  not  successfully 
integrate acquired businesses or recognize the anticipated benefits, which could adversely affect our operating results. 

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

Operating risks, such as: 
(cid:129) 
(cid:129) 
(cid:129) 
(cid:129) 
(cid:129) 

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. 

(cid:129) 

Financial risks, such as: 
(cid:129) 
(cid:129) 
(cid:129) 

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. 

(cid:129) 
(cid:129) 
(cid:129) 

In fiscal 2012, we pursued growth through a strategic arrangement with Kontron AG ("Kontron"), as previously disclosed.  Our 
results may be adversely affected if this arrangement does not deliver the expected revenues and/or margins. 

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.

ITEM 3.  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. In August 2012, CBP issued its final determination of duties and fees owed by Plexus. We 
have paid into a CBP-maintained escrow account the duties and fees claimed by CBP, pending a ruling from CBP Headquarters 
which could reduce the duties and fees owed by Plexus. Plexus has implemented improved processes and procedures and has 
reviewed 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. The accrual 
has been reduced to reflect our payment into the CBP escrow account.  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.    As  a  result  of  the 
anticipated resolution of this matter, we do not intend to further report on it absent material developments. 

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 14, 2012, there were approximately 600 shareholders of record. We have not paid any cash dividends in the 
past. 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  Resources”,  for  a  discussion  of  the 
Company’s intentions regarding dividends, and loan covenants which could restrict dividend payments. 

Issuer Purchases of Equity Securities 

On  October  23,  2012,  the  Company's  Board  of  Directors  approved  a  share  repurchase  program  that  authorizes  Plexus  to 
repurchase up to  $50  million  of  its  common  stock.    However, Plexus  did  not  repurchase  any  shares of  its  common  stock  in 
fiscal 2012.

In fiscal 2012, we established a valuation allowance against our U.S. deferred tax assets resulting in an additional tax 
provision  of  approximately  $20.6  million  ($22.8  million  provision,  offset  by  $2.2  million  to  other  comprehensive 
income) and a decrease in diluted earnings per share of $0.64.  Return on invested capital excludes the $20.6 million net 
deferred tax asset reduction.    

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 Mexico.

The  Company  defines  return  on  invested  capital  as  tax-effected  annualized  operating  income  divided  by  average 
invested  capital  over  a rolling  five-quarter period.    Invested capital  is  defined  as  equity  plus debt,  less  cash  and  cash 
equivalents.

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  ("AMER"),  Europe,  Middle  East  and  Africa  ("EMEA")  and  Asia-Pacific  ("APAC")  regions. 
Customer  service  is  provided  to  over  140  branded  product  companies  in  the  Networking/Communications,  Healthcare/Life 
Sciences,  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. 

Beginning in fiscal 2013, we renamed our Medical market sector as the Healthcare/Life Sciences market sector.  This change 
stems from our evolving strategy and enhanced capabilities within this market and reflects the industry's progression to holistic 
patient care.  We believe Healthcare/Life Sciences more accurately defines this growing industry and aligns with our existing 
and targeted customer base. 

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.

Net sales. Net sales for fiscal 2012 increased $75.5 million, or 3.4 percent, as compared to fiscal 2011. The net sales increase 
resulted from higher net sales in all of our market sectors, except for a decrease in the networking/communications sector.  The 
net sales increase primarily related to the continued ramp of production for a significant industrial/commercial sector customer  
and  $81.9  million  of  incremental  revenue  from  the  previously  announced  strategic  arrangement  with  Kontron  (the  "Kontron 
arrangement"),  as  well  as  program  ramps  from  several  other  existing  customers.    These  increases  in  net  sales  were  partially 
offset by decreased sales in the networking/communications sector due to lower end-market demand and the two previously 
announced  customer  disengagements  due  to  the  acquisition  of  such  customers.    See  below  regarding  an  intended 
disengagement by Juniper, our largest customer. 

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 networking/communications sector. The net sales 
increase  primarily  related  to  the  ramp  of  production  for  a  then-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 healthcare/life sciences sectors during fiscal 2011, which were partially offset by the two customer 
disengagements noted above in the networking/communications market sector. 

Our net sales by market sector for fiscal 2012, 2011 and 2010 were as follows (in millions):

Networking/Communications.  Net  sales  for  the  networking/communications  sector  decreased $126.3  million  for  fiscal  2012 
compared to fiscal 2011. The decline in the sector was primarily the result of the impact from the prior year disengagement of 
two  significant  customers  noted  above  of  approximately  $74.9  million  and  overall  unfavorable  end-market  trends  reflecting 
global economic uncertainty.  Net sales to Juniper did not change significantly from fiscal 2011. 

Net  sales  for  the  networking/communications  sector  decreased  $70.1  million  for  fiscal  2011  compared  to  fiscal  2010.  The 
decline in the sector was a result of the disengagements and end-market trends noted above.  Net sales to Juniper in fiscal 2011 
increased  as  a  result  of  improved  end-market  demand  for  the  mix  of  Juniper  products  we  produce  as  well  as  new  product 
launches. 

Industrial/Commercial.  Net  sales  for  the  industrial/commercial  sector  increased  $142.8  million  for  fiscal  2012  compared  to 
fiscal  2011.  The  increase  was  primarily  attributable  to  the  continued  ramp  of  a  significant  customer  and  $81.9  million  of 
incremental revenue related to the Kontron arrangement, as well as the addition of a new customer in this sector. 

Net sales for the industrial/commercial sector increased $169.0 million for fiscal 2011 compared to fiscal 2010. The increase in 
the sector was a result of the ramp of production for the significant customer noted above.   

Healthcare/Life Sciences. Net sales for the healthcare/life sciences sector increased $24.2 million for fiscal 2012 compared to 
fiscal 2011. The increase was primarily due to market share gain and new programs with existing customers. 

Net sales for the healthcare/life sciences sector increased $70.9 million for fiscal 2011 compared to fiscal 2010. The increase 
was due to higher overall end-market demand in the market sector.   

Defense/Security/Aerospace.  Net  sales  for  the  defense/security/aerospace  sector  increased  $34.8  million  for  fiscal  2012 
compared to fiscal 2011. The increase was primarily due to stronger end-market demand in the aerospace market as well as the 
addition of a new customer in this sector. 

Net  sales  for  the  defense/security/aerospace  sector  increased  $48.0  million  for  fiscal  2011  compared  to  fiscal  2010.  The 
increase in the sector was primarily due to increased demand from an existing customer as a result of new program wins and a 
program ramp for a new customer.

The percentages of net sales to customers representing 10 percent or more of net sales and net sales to our ten largest customers 
for fiscal 2012, 2011 and 2010 were as follows:

On  November  5,  2012,  Juniper  notified  us  that  it  will  disengage  with  Plexus.    The  specific  timing  of  the  transition  of  the 
Juniper business from Plexus is not known at this time, although it is currently expected to occur by the end of fiscal 2013.  The 
Company is currently evaluating the financial, operational and other impacts of the disengagement. 

Gross  profit.  For  fiscal  2012,  gross  profit  increased  $5.2  million  compared  to  fiscal  2011  primarily  due  to  the  net  sales 
increase.    The  increase  was  partially  offset  by  increased  fixed  expenses  related  to  higher  headcount  to  support  the  revenue 
growth, costs related to the addition of a fourth facility in Penang, Malaysia of approximately $5.9 million, transition costs due 
to the Kontron arrangement, and an unfavorable change in customer mix.  Customer mix negatively impacted gross profit due 
to a higher portion of sales from new programs, which tend to be inherently less profitable during early production stages than 
mature  programs.    Gross  profit  was  also  negatively  impacted  by  escalated  pricing  pressure,  particularly  in  our 
networking/communications sector.  These factors led to the reduction in gross margin from 9.6 percent for fiscal 2011 to 9.5 
percent for fiscal 2012.  

For fiscal 2011, gross profit increased $7.8 million compared to fiscal 2010 primarily due to increased net sales in all of our 
market sectors except networking/communications, 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.  This increase was 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 ramped 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.  These factors led to the reduction in gross 
margin from 10.3 percent for fiscal 2010 to 9.6 percent for fiscal 2011.  

Operating income. For fiscal 2012, operating income increased $3.0 million compared to fiscal 2011. The operating income 
increase reflected the $5.2 million increase in gross profit described above, partially offset by a $2.2 million increase in selling 
and administrative expenses (“S&A”).  The dollar increase in S&A is primarily due to a $1.5 million increase in stock-based 
compensation  expense,  $1.3  million  of  amortization  expense  resulting  from  an  intangible  asset  related  to  the  Kontron 
arrangement, and an increase in other personnel expenses.  These increases were partially offset by approximately $2.4 million 
of recoveries of receivables previously at risk.  As a result of the factors discussed above, for fiscal 2012 compared to fiscal 
2011, operating margin remained at 4.5 percent. 

For fiscal 2011, operating income increased $1.5 million compared to fiscal 2010. The operating income increase reflected the 
$7.8 million increase in gross profit described above, partially offset by a $6.3 million increase in S&A. 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. These increases were partially offset by approximately $4.1 million of lower variable incentive compensation in fiscal 
2011 as compared to fiscal 2010.  The above factors led to a reduction of operating margin to 4.5 percent for fiscal 2011 from 
4.9 percent for fiscal 2010. 

Other  income  (expense).  Other  expense  increased  to  $12.9  million  for  fiscal  2012  from  $9.1  million  for  fiscal  2011.  The 
increase  in  expense  was  largely  due  to  $4.4  million  of  increased  interest  expense  primarily  related  to  the  $175  million  of 
borrowings  under  the  Note  Purchase  Agreement  that  the  Company  entered  into  during  the  third  quarter  of  fiscal  2011,  as 
discussed in "Liquidity and Capital Resources" below. 

Other  expense  for  fiscal  2011  decreased  to  $9.1  million  from  $9.2  million  in  fiscal  2010.  This  change  was  driven  by  the 
favorable  fluctuation  in  foreign  currency  transactions  of  $2.4  million,  partially  offset  by  increased  interest  expense  of  $2.1 
million,  primarily  related  to  the  $175  million  of  borrowings  noted  above,  which  we  entered  into  during  the  third  quarter  of 
fiscal 2011, as discussed in “Liquidity and Capital Resources” below.

Income taxes. Income taxes and effective annual income tax rates for fiscal 2012, 2011 and 2010 were as follows (dollars in 
millions): 

Income tax expense, as reported  
Effective annual tax rate, as reported  

2012 
$29.1 
31.9% 

2011 
$2.8 
3.1% 

2010 
$0.9 
1.0% 

Income tax expense for fiscal 2012 increased to $29.1 million compared $2.8 million for fiscal 2011 and $0.9 million for fiscal 
2010, as a result of the increase in our effective tax rate.  These rates primarily vary from the U.S. statutory rate of 35 percent 
as a result of the amount of earnings from different U.S. and foreign jurisdictions, and tax holidays granted to our subsidiaries 
in  China  and  Malaysia,  where  we  derive  a  significant  portion  of  our  earnings.  The  effective  tax  rate  for  fiscal  2012  is 
significantly higher than the effective rate for fiscal 2011 primarily as a result of the additional valuation allowance recorded on 
deferred tax assets in the U.S. of $22.8 million, which is discussed further below.  The fiscal 2012 effective tax rate, adjusted 
for the valuation allowance to 7%, and the effective tax rate for fiscal 2011 were higher than the effective tax rate for 2010 
primarily as a result of increased profitability in the U.S. tax jurisdiction.  Our effective tax rate could fluctuate in the future 
depending on the geographic distribution of our worldwide earnings.  

During the preparation of the Company's fiscal 2012 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.”  Under these accounting rules, the weight given to positive 
and  negative  evidence  is  proportionate  with  the  extent  to  which  the  evidence  may  be  objectively  verified.    It  is  generally 
difficult for positive evidence regarding projected future taxable income exclusive of reversing taxable temporary differences to 
outweigh objectively verifiable negative evidence of recent financial reporting losses. Accordingly, as of September 29, 2012, 
the Company established an additional valuation allowance of $20.6 million ($22.8 million provision, offset by $2.2 million to 
other comprehensive income) against our U.S. deferred tax assets.  This was based on the significant negative evidence of the 
Company's U.S. cumulative loss position and the deterioration of our forecasts late in the fourth quarter of fiscal 2012 for fiscal 
2013, which has impacted forecasted profitability in the near term in the AMER region.  

We currently expect the annual effective tax rate for fiscal 2013 to be approximately 6 to 8 percent. The rate is consistent with 
the fiscal 2012 rate before the effects of the valuation allowance are taken into account.   

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.  The expiration 
of the tax holiday in China is not expected to have a material impact on the effective tax rate.  However, we cannot provide any 
assurances as to the effect and will continue to monitor the projected impact.  In fiscal 2012, 2011 and 2010, these subsidiaries 
generated income, which resulted in tax reductions of approximately $17.5 million ($0.50 per basic share), $21.7 million ($0.57 
per basic share) and $23.0 million ($0.58 per basic share), respectively. 

Net Income.  Primarily as a result of the valuation allowance adjustment discussed above, net income for fiscal 2012 decreased 
by $27.2 million, or 30.4 percent, to $62.1 million from fiscal 2011.  Excluding the valuation allowance adjustment, net income 
was $84.9 million, a decrease of $4.4 million, or 4.9 percent from fiscal 2011 as a result of higher fixed expenses and increased 
interest expense, partially offset by the effect of higher net sales. 

Primarily as a result of lower gross margins and increases to income tax expense, net income for fiscal 2011 decreased by $0.3 
million, or 0.3 percent, to $89.3 million from fiscal 2010.  

Diluted earnings per share. Diluted earnings per share decreased to $1.75 for fiscal 2012 from $2.30 for fiscal 2011 primarily 
as  a  result  of  the  valuation  allowance  adjustment  discussed  above.    Excluding  the  valuation  allowance  adjustment,  diluted 
earnings  per  share  increased  to  $2.39  for  fiscal  2012.    The  increase  in  diluted  earnings  per  share  excluding  the  valuation 
allowance adjustment was primarily due to the effect of a decrease in diluted weighted average shares outstanding as a result of 
our share repurchases completed late in fiscal 2011, partially offset by lower net income. 

Diluted earnings per share increased to $2.30 for fiscal 2011 from $2.19 for fiscal 2010.  The increase in diluted earnings per 
share  was  primarily  due  to  the  effect  of  a  decrease  in  diluted  weighted  average  shares  outstanding  as  a  result  of  our  share 
repurchases completed in fiscal 2011, partially offset by the slight decrease in net income previously noted.

Return  on  Invested  Capital  (“ROIC”).  We  use  a  5-10-5  financial  model  which  is  aligned  with  our  business  strategy,  and 
includes a ROIC goal of 500 basis points over our weighted average cost of capital (“WACC”), a 10% gross margin target and 
a 5% operating margin target. Our primary focus is our ROIC goal, which is designed to create shareholder value and generate 
enough cash to self-fund our targeted organic revenue growth rate of 15%. 

We  review  our  internal  calculation  of  WACC  annually,  and  our  estimated  WACC  was  12.5  percent  for  fiscal  2012.  By 
exercising discipline  to generate  ROIC  in  excess of  our WACC,  our  goal  is  to  create  value  for  our shareholders. ROIC was 
15.5%  (excluding  $20.6  million  net  deferred  tax  asset  reduction),  15.6%  and  19.5%  for  fiscal  2012,  2011  and  2010, 
respectively. The decrease from fiscal 2011 to fiscal 2012 was due primarily to slightly lower tax-effected annualized operating 
income as a result of a higher effective tax rate.  See the table below for our calculation of ROIC (dollars in millions):

We define ROIC as tax-effected annualized operating income divided by average invested capital over a rolling five-quarter 
period for the fiscal year. Invested capital is defined as equity plus debt, less cash and cash equivalents. Other companies may 
not define or calculate ROIC in the same way. ROIC is a non-GAAP financial measure which should be considered in addition 
to, not as a substitute for, measures of our 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 because we view ROIC as an important measure in evaluating the efficiency 
and effectiveness of our long-term capital requirements. We also use a derivative measure of ROIC as a performance criteria in 
determining certain elements of compensation. 

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.

Americas (AMER): 

Net  sales  for  fiscal  2012  decreased  $49.0  million,  or  3.8  percent,  from  fiscal  2011,  primarily  as  a  result  of  decreased  end-

networking/communications customers, one as a result of a previously announced customer disengagement and the other as a

offset by the ramp of production for our significant industrial/commercial sector customer and the addition of a new customer 
in this sector as well.  Net sales to Juniper did not change significantly from fiscal 2011.  Operating income for fiscal 2012 
increased  $22.4  million  from  fiscal  2011  due  to  a  favorable  customer  mix,  an  increase  in  engineering  design  and  services 
profitability of approximately $5.1 million and $2.4 million of recoveries of receivables previously at risk. 

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  networking/communications  customers,  as  noted  above.  Operating  income  for  fiscal 
2011 decreased $5.7 million from fiscal 2010 due to fiscal 2010 benefiting from a $3.2 million litigation settlement, as well as 
unfavorable changes in customer mix in fiscal 2011. 

Asia-Pacific (APAC): 

Net sales for fiscal 2012 increased $47.3 million, or 4.4 percent, from fiscal 2011. This growth reflected incremental revenue 
from  the  Kontron  arrangement  of  approximately  $81.9  million  as  well  as  higher  net  sales  to  multiple  customers  across  our 
market sectors. These increases were partially offset by decreased net sales from the previously announced disengagement of 
one  customer  in  the  networking/communications  sector  and  a  decline  in  end-market  demand  for  the  mix  of  products  we 
produce for another customer in this sector as well for an industrial/commercial sector customer.  Operating income decreased 
$16.2 million in fiscal 2012 as compared to fiscal 2011, primarily as a result of costs related to the addition of a fourth facility 
in  Penang,  Malaysia  of  approximately  $5.9  million,  increased  expenses  related  to  higher  headcount  to  support  capacity 
investments, transition costs for the Kontron arrangement and escalated pricing pressure. 

Net sales for fiscal 2011 increased $137.7 million, or 14.9 percent, from 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 networking/communications sector as well as a drop in end-market demand for the mix of products we produce 
for an additional networking/communications 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 unfavorable changes in customer mix and higher 
fixed expenses. 

Europe, Middle East and Africa (EMEA): 

Net sales for fiscal 2012 increased $3.2 million, or 3.5 percent, from fiscal 2011. The increase in net sales was driven primarily 
by  the  addition  of  new  customers  in  each  of  our  market  sectors,  partially  offset  by  decreased  net  sales  to  an 
industrial/commercial  customer  as  a  result  of  reduced  end-market  demand  for  the  mix  of  products  we  produce  for  that 
customer.    Operating  results  improved  in  the  current  year  as  compared  to  the  prior  year  due  to  increased  profitability  in 
Romania based on the mix of customers and increased leverage at the facility.   

Net  sales  for  fiscal  2011  increased  $19.6  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 fiscal 2011 as compared to fiscal 2010 due to increased operating costs from our Romania facility and our 
new engineering facility in Darmstadt, Germany. 

LIQUIDITY AND CAPITAL RESOURCES 

Cash and cash equivalents were $297.6 million as of September 29, 2012 compared to $242.1 million as of October 1, 2011. 
The  increase  in  the  balance of our  cash  and  cash  equivalents  was due primarily  to  cash  generated  from  operations,  partially 
offset by cash used for the Kontron arrangement, capital expenditures and payments on debt. 

As  of  September 29,  2012,  approximately  two-thirds  of  our  cash  balance  was  held  outside  of  the  U.S.  by  our  foreign 
subsidiaries.  Certain  foreign  countries  impose  taxes  and  overall  penalties  on  transfers  of  cash;  however,  our  intent  is  to 
permanently reinvest funds held in these countries. If this cash were remitted to the U.S., additional tax obligations may result 
that would reduce the amount of cash ultimately available to us in the U.S. Currently, we believe that cash held in the U.S., 
together with cash available under U.S. credit facilities and cash from foreign subsidiaries that could be remitted to the U.S. 

31 

 
without tax consequences, will be sufficient to meet our U.S. liquidity needs for the next twelve months and for the foreseeable 
future.

Operating  Activities. Cash  flows  provided  by  operating  activities  were  $157.5  million  for  fiscal  2012,  as  compared  to  cash 
flows provided by operating activities of $158.5 million for fiscal 2011.  Cash flows provided by operating activities decreased 
slightly due to lower net income, partially offset by overall improved working capital management. 

Cash flows provided by operating activities were $158.5 million for fiscal 2011, as compared to cash flows used in operating 
activities of $(7.6) million for fiscal 2010.  During fiscal 2011, the increase in cash flows provided by operating activities was 
primarily the result of improvements in working capital management.

We calculate days in accounts receivable as accounts receivable for the respective quarter divided by annualized sales for the 
respective quarter by day. We calculate days in inventory, accounts payable, and cash deposits as each balance sheet line item 
for the respective quarter divided by annualized cost of sales for the respective quarter by day. 

Days  in  accounts  receivable  for  the  three  months  ended  September 29,  2012  increased  by  one  day  compared  to  the  three 
months ended October 1, 2011, primarily due to the timing of net sales at the end of the current year period.   

Days  in  inventory  for  the  three  months  ended  September 29,  2012  decreased  by  seven  days  compared  to  the  three  months 
ended October 1, 2011, due to our efforts to actively manage inventory levels down with the assistance of our customers, while 
continuing to meet our customers’ needs for flexibility and agility as well as support revenue growth. 

Days in accounts payable for the three months ended September 29, 2012 increased by one day compared to the three months 
ended October 1, 2011, primarily due to the timing of the purchases during the quarter.    

Days in cash deposits for the three months ended September 29, 2012 were consistent with the three months ended October 1, 
2011 at six days.  

We calculate cash cycle as the sum of days in accounts receivable and days in inventory, less days in accounts payable and 
days in cash deposits. As of September 29, 2012 cash cycle days decreased by seven days compared to  October 1, 2011 due to 
the factors noted above. 

Free  Cash  Flow.    Free  cash  flow  (“FCF”),  which  we  define  as  cash  flow  provided  by  (used  in)  operations  less  capital 
expenditures,  increased  for  fiscal  2012,  to  $93.8  million,  as  compared  to  FCF  of  $87.6  million  for  fiscal  2011.  Better 
management of working capital partially offset by lower net income led to this improvement for fiscal 2012. 

FCF  is  a  non-GAAP  financial  measure  which  should  be  considered  in  addition  to,  not  as  a  substitute  for,  measures  of  our 
financial performance prepared in accordance with U.S. GAAP.  We provide FCF because we believe it offers insight into the 

32 

 
 
 
 
 
 
 
 
 
 
 
 
metrics that are driving management decisions. We view FCF as an important financial metric as it demonstrates our ability to 
generate cash and allows us to pursue opportunities that enhance shareholder value.   

Below  is  a  reconciliation  of  FCF  to  our  financial  statements  that  was  prepared  using  GAAP  for  fiscal  2012  and  2011  (in 
millions):

Investing  Activities. Cash  flows  used  in  investing  activities  totaled  $92.2  million  for  fiscal  2012  as  compared  to  cash  flows 
used in investing activities of $68.7 million for fiscal 2011. Cash flows used in investing activities increased primarily due to 
the  expenditure  of  $34.2  million  of  cash  related  to  the  Kontron  arrangement  in  fiscal  2012.    Cash  flows  used  in  investing 
activities  for  fiscal  2011  increased  slightly  from  fiscal  2010  to  $68.7  million  primarily  due  to  capital  expenditures  for  new 
facilities in Penang, Malaysia and Xiamen, China. 

We utilized available cash and operating cash flows as the sources for funding our operating requirements during fiscal 2012. 
We currently estimate capital expenditures for fiscal 2013 to be approximately $100 million.  A significant portion of the fiscal 
2013 capital expenditures is anticipated to be used for the construction of our previously announced manufacturing facilities in 
Neenah,  Wisconsin  and  Oradea,  Romania  to  replace  leased  buildings  in  both  locations.  We  believe  the  estimated  capital 
expenditures  will  continue  to  be  funded  from  operations,  and  may  be  supplemented  by  short-term  borrowings,  if  required, 
although we can provide no assurances. 

Financing Activities. Cash flows used in financing activities totaled $10.8 million for fiscal 2012, as compared to cash flows 
used  in  financing  activities  of  $37.0  million  for  fiscal  2011.    Cash  flows  used  in  financing  activities  for  fiscal  2012  were 
comprised primarily of payments on debt, partially offset by debt proceeds and proceeds from the exercise of stock options.   
Cash flows used in financing activities for fiscal 2011 were comprised primarily of repurchases of common stock and payments 
on debt, partially offset by debt proceeds and proceeds from the exercise of stock options.  Cash flows provided by financing in 
fiscal 2010 were primarily due to proceeds from the exercise of stock options, partially offset by payments on our term debt 
and capital leases. 

On  May 15,  2012,  the  Company  entered  into  a  five-year,  $250  million  senior  unsecured  credit  facility  that  terminates  on 
May 15, 2017 (the “Credit Facility”). The Credit Facility includes a $160 million revolving credit facility and a $90 million 
term loan. The revolving credit facility potentially may be increased by $100 million (the "increase option") to $260 million 
generally by mutual agreement of the Company, the lenders, the letter of credit issuers and the administrative agent named in 
the related credit agreement (the "Credit Agreement"), subject to certain customary conditions. The Credit Facility was used to 
refinance the Company's then-existing $100 million senior unsecured revolving credit facility (no amounts were outstanding as 
of May 15, 2012) and its $150 million senior unsecured term loan (balance of $90.0 million as of May 15, 2012), both of which 
were scheduled to mature on April 4, 2013, and for general corporate purposes.  Quarterly principal repayments of the Credit 
Facility term loan of $3.75 million per quarter began June 29, 2012 and end on March 28, 2013.  The final $75 million payment 
is due on May 15, 2017.     

The financial covenants (as defined under the Credit Facility) require that the Company maintain, as of each fiscal quarter end, 
a  maximum  total  leverage  ratio  and  a  minimum  interest  coverage  ratio.    As  of  September 29,  2012,  the  Company  was  in 
compliance  with  all  covenants  of  the  Credit  Facility.    Borrowings  under  the  Credit  Facility,  at  the  Company's  option,  bear 
interest at a defined base rate or the LIBOR rate plus, in each case, an applicable margin based upon the Company's leverage 
ratio as defined in the Credit Agreement.  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% or the base rate plus 
0%. We are also required to pay an annual commitment fee on the unused revolver credit commitment based on our leverage 
ratio; the fee was 0.20% as of September 29, 2012.  

During the third quarter of fiscal 2011, we entered into a Note Purchase Agreement (the “Note Purchase Agreement”) for $175 
million  in  principal  amount  of  5.20%  Senior  Notes,  due  June 15,  2018  (the  “Notes”).  We  issued  $100  million  in  principal 
amount of the Notes on April 21, 2011, and the remaining $75 million on June 15, 2011.    

33 

 
 
 
 
 
The Note Purchase Agreement contains certain financial covenants, which include a maximum total leverage ratio, a minimum 
interest coverage ratio and a minimum net worth test, all as defined in the agreements. As of September 29, 2012, we were in 
compliance with all debt covenants. 

The Credit Facility and Note Purchase Agreement allow 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. We have not paid cash dividends in the past and do not 
currently anticipate paying them in the future. However, we evaluate from time to time potential uses of excess cash, which in 
the future may include share repurchases, a special dividend or recurring dividends. 

On October 23, 2012, the Company received approval from the Board of Directors for a new stock repurchase program under 
which the Company is authorized to repurchase up to $50 million of its common stock.  It is anticipated that this program will 
be funded with existing cash and is expected to be executed quarterly, on a relatively consistent basis, during fiscal 2013. 

Based on current expectations, we believe that our projected cash flows from operations, available cash and cash equivalents, 
the Credit Facility, and our leasing capabilities should be sufficient to meet our working capital and fixed capital requirements 
for the next twelve months and for the foreseeable future. Further, $160 million of committed credit is currently available under 
the Credit Facility, with another $100 million potentially available pursuant to the increase option. 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 uncertainty of the 
credit and financial markets, we cannot be assured that we will be able to make any such arrangements on acceptable terms. 

Additionally, the Company enters interest rate swaps and foreign currency derivatives to hedge against variable cash flows.  All 
derivatives are recognized on the Consolidated Balance Sheets at their estimated fair value.  The Company does not enter into 
derivatives for speculative purposes.  See Note 6 - Derivatives and Fair Value Measurements for further details. 

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 the Notes 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.

During  the  third  quarter of  fiscal  2011, we  entered  into  the Note Purchase  Agreement  and  issued  $175.0  million  in 
principal  amount  of  notes.    As  of  September 29,  2012,  the  outstanding  balance  was  $175.0  million.    The  amounts 
listed above include interest; see Note 5 in Notes to Consolidated Financial Statements for further information. 

As of September 29, 2012, purchase obligations consist of commitments to purchase inventory and equipment in the 
ordinary course of business. 

As  of  September 29,  2012,  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  $7.6  million,  as  of 
September 29, 2012, 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  September 29,  2012,  other  long-term  obligations  not  on  the  balance  sheet  consisted  of  commitments  to  build 
new  manufacturing  facilities  in  Neenah,  Wisconsin  and  Oradea,  Romania  as  well  as  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 we believe are material.  

DISCLOSURE ABOUT CRITICAL ACCOUNTING POLICIES 

Our accounting policies are disclosed in Note 1 of Notes to the Consolidated Financial Statements. During fiscal 2012, 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  10  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. 

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 

35 

 
 
 
 
 
 
“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 6 – 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  potentially  enhance  the  likelihood  of  realization  of  a  deferred  tax  asset.    In  the  fourth  quarter  of  fiscal 
2012, as a result of a reduction in forecasted near term profitability in the AMER region, we established a valuation allowance 
resulting in an additional tax provision of approximately $22.8 million, with an offset to other comprehensive income of $2.2 
million, for a net additional allowance amount of $20.6 million.

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.    We 
enter  into  forward  contracts  to  hedge  a  portion  of  our  foreign  currency  denominated  transactions  in  our  APAC  reportable 
segment, as described in Note 6, "Derivatives and Fair Value Measurements," to Notes to Consolidated Financial Statements. 

Our percentages of transactions denominated in currencies other than the U.S. dollar for fiscal 2012, 2011, and 2010 were as 
follows: 

Net Sales 
Total Costs 

2012 
5%

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 September 29, 
2012, 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 based on existing market conditions. We have entered into 
interest  rate  swaps  for  $82.5  million  in  term  loans,  as  described  in  Note  6,  "Derivatives  and  Fair  Value  Measurements,"  in 
Notes to Consolidated Financial Statements. As is common with these types of agreements, our interest rate swaps 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 September 29, 2012, is associated with our Credit Facility under which we borrowed 
$90 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.

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  September 29,  2012,  based  on  the  criteria 
established  in  “Internal  Control  –  Integrated  Framework”  issued  by  the  Committee  of  Sponsoring  Organizations  of  the 
Treadway  Commission  (“COSO”).  Based  on  its  assessment  and  those  criteria,  management  of  the  Company  has  concluded 
that, as of September 29, 2012, the Company’s internal control over financial reporting was effective. 

The independent registered public accounting firm of PricewaterhouseCoopers LLP has audited the Company’s internal control 
over financial reporting as of September 29, 2012, as stated in their report included herein on page 42. 

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. 

37 

 
 
  
  
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 September 29, 2012 and October 1, 2011, and the results of their 
operations  and  their  cash  flows  for  each  of  the  three  years  in  the  period  ended  September 29,  2012  in  conformity  with 
accounting principles generally accepted in the United States of America.  In addition, in our opinion, the financial statement 
schedule listed in the accompanying index presents fairly, in all material respects, the information set forth therein when read in 
conjunction with the related consolidated financial statements.  Also in our opinion, the Company maintained, in all material 
respects, effective internal control over financial reporting as of September 29, 2012, 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.

Notes to Consolidated Financial Statements 

1. 

Description of Business and Significant Accounting Policies 

Description of Business:  Plexus Corp. and its subsidiaries (together “Plexus” or the “Company”) participate in the Electronic 
Manufacturing Services (“EMS”) industry. Plexus delivers 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"),  Europe,  Middle  East,  and  Africa  ("EMEA"),  and  Asia-Pacific 
("APAC") regions. Customer service is provided to over 140 branded product companies in the Networking/Communications, 
Healthcare/Life Sciences, Industrial/Commercial and Defense/Security/Aerospace market sectors. The Company's 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  the  Company's  customers’  products 
require  complex  configuration  management  and  direct  order  fulfillment  to  their  customers  across  the  globe.  In  such  cases 
Plexus  provides  global  logistics  management  and  after-market  service  and  repair.  The  Company's  customers’  products  may 
have  stringent  requirements  for  quality,  reliability  and  regulatory  compliance.  Plexus  offers  its  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.  The 
accounting years for fiscal 2012, 2011 and 2010 each included 364 days. 

The  Company’s  reportable  segments  consist  of  the  AMER,  APAC  and  EMEA  segments.  Refer  to  Note  12,  "Reportable 
Segments, Geographic Information and Major Customers," for further details on reportable segments.  

Revision of Prior Period Financial Statements:  During the second quarter of fiscal 2012, the Company revised its previously 
issued  financial  statements  as  a  result  of  a  correction  to  the  classification  of  upfront  payments  made  for  land  use  rights  in 
certain  foreign  countries.  Refer  to  Note  16,  "Revision  of  Prior  Period  Financial  Statements,"  for  further  discussion  of  these 
revisions. 

Cash and Cash Equivalents:  Cash equivalents are highly liquid investments purchased with an original maturity of less than 
three  months  and  are  classified  as  Level  1  in  the  fair  level  hierarchy  described  below.    As  of  September 29,  2012  and 
October 1, 2011, cash and cash equivalents were the following (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.

Plexus Corp. 
Notes to Consolidated Financial Statements 

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 
  3-10 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  4,  "Property,  Plant  and  Equipment")  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. 

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 for each of fiscal 2012, 
2011 and 2010. 

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  7,  "Income  Taxes").  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:  The Company translates 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.  The  Company 
translates 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

Notes to Consolidated Financial Statements 

included  in  our  Statements  of  Operations  as  a  component  of  miscellaneous  income  (expense).  Exchange  gains  (losses)  on 
foreign currency transactions were $0.2 million, $1.0 million, and $(1.5) million for fiscal 2012, 2011 and 2010, 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 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. The Company's interest rate swaps and forward contracts are treated as cash flow hedges and, therefore, 
$6.8  million,  $(0.4)  million  and  $2.0  million  were  recorded  in  “Accumulated  other  comprehensive  income”  for  fiscal  2012, 
2011 and 2010, respectively. 

Grants  from Government  Authorities:   Grants  from  governments  are  recognized  at  their  fair value where  there  is  reasonable 
assurance that the grant funds will be received and the Company will comply with all attached conditions to the grant.  

Government grants relating to property, plant and equipment are recorded as an offset to the carrying value of the related assets 
at  the  time  of  capitalization.    Government  grants  relating  to  other  costs  incurred  are  recognized  as  an  offset  to  those  related 
costs, for which the grants are intended to compensate for, at the time they are recognized. 

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  September 29,  2012  and  October 1,  2011  (in 
thousands):

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 6, "Derivatives and Fair Value Measurements." 

Conditional  Asset  Retirement  Obligations:  The  Company  recognizes  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 ("GAAP") 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 $13.7 million and $15.8 million as of September 29, 2012 and October 1, 2011, respectively. The fair value of 
the  Company’s  long-term  debt  was  $256.8  million  and  $274.3  million  as  of  September 29,  2012  and  October 1,  2011, 
respectively.    The  Company  uses  quoted  market  prices  when  available  or  discounted  cash  flows  to  calculate  fair  value.    If 

49 

 
 
 
 
Plexus Corp. 
Notes to Consolidated Financial Statements 

measured at fair value in the financial statements, long-term debt and capital lease obligations (including the current portion) 
would be classified as Level 2 in the fair value hierarchy described below.  The fair values of the Company’s derivatives are 
disclosed in Note 6, "Derivatives and Fair Value Measurements."  

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 12, "Reportable Segments, Geographic Information and Major Customers."  The Company, at times, requires advanced 
cash deposits for services performed. The Company also closely monitors extensions of credit. 

New  Accounting  Pronouncements:  In  December  2011,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  an 
amendment  to  disclosures  about  offsetting  assets  and  liabilities.  The  amended  standard  requires  an  entity  to  disclose 
information  about  offsetting  and  related  arrangements  to  enable  users  of  its  financial  statements  to  understand  the  effect  of 
those  arrangements  on  its  financial  position.  An  entity  is  required  to  apply  the  amendments  for  annual  reporting  periods 
beginning on or after January 1, 2013, and interim periods within those annual periods. An entity should provide the disclosures 
required by those amendments retrospectively for all comparative periods presented. 

In June 2011, the 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.  

Reclassifications:    Certain  amounts  in  prior  year  periods  within  financing  activities  on  the  Consolidated  Statements  of  Cash 
Flows were reclassified to conform to current year presentation.

Business Combination 

In the second quarter of fiscal 2012, Plexus and Kontron AG (“Kontron”) entered into a strategic manufacturing arrangement, 
and  completed  the  related  asset  purchase  transaction  described  below.    Under  this  arrangement,  Kontron  transitioned  all 
manufacturing  of  its  Kontron  Design  Manufacturing  Services  (M) Sdn.  Bhd.  subsidiary  (“KDMS”)  located  in  Penang, 
Malaysia to Plexus facilities in Penang.  Plexus acquired the inventory and equipment of KDMS for an adjusted purchase price 
of $34.2 million, reflecting certain post-closing adjustments, which was paid with cash on-hand, and hired substantially all of 
KDMS's  employees.    No  real  estate  was  included  in  this transaction.    This  transaction  has  been  accounted  for  as  a business 
combination. The purchase price was allocated primarily to inventory and equipment.  An identifiable intangible asset of $4.0 
million  related  to  a  customer  relationship  was  recorded  within  other  non-current  assets  in  the  Company's  accompanying 
Consolidated  Balance  Sheets  as  a  result  of  the  arrangement  and  will  be  amortized  on  a  straight-line  basis  over  a  two  year 
period. Under this arrangement, Kontron also committed to approximately $100 million of incremental revenue annually for 
two  years.    Assuming  this  transaction  had  been  made  at  the  beginning  of  any  period  presented,  the  consolidated  pro  forma 
results would not have been materially different from reported results.

The building and improvements category in the above table includes a manufacturing facility in San Diego, California, which 
was closed during fiscal 2003 and is no longer used by the Company. The Company has subleased the facility. The San Diego 
facility is recorded at the net present value of the sublease income, net of cash outflows for broker commissions and building 
improvements associated with the subleases. The net book value of the San Diego facility is reduced on a monthly basis by the 
amortization of the sublease cash receipts, net of certain cash outflows associated with the subleases. The net book value of the 
San Diego facility is approximately $8.4 million as of September 29, 2012. 

Amortization of assets held under capital leases totaled $0.8 million, $0.9 million, and $1.0 million for fiscal 2012, 2011 and 
2010, respectively. There were $0.1 million capital lease additions in fiscal 2012, $0 million for fiscal 2011 and $0.9 million for 
fiscal 2010. 

As  of  September 29,  2012  ,  October 1,  2011  and  October 2,  2010,  accounts  payable  included  approximately  $11.5  million, 
$12.3 million and $6.3 million, respectively, related to the purchase of property, plant and equipment, which have been treated 
as non-cash transactions for purposes of the Consolidated Statements of Cash Flows.

On  May 15,  2012,  the  Company  entered  into  a  five-year,  $250  million  senior  unsecured  credit  facility  that  terminates  on 
May 15, 2017 (the “Credit Facility”). The Credit Facility includes a $160 million revolving credit facility and a $90 million 
term loan. The revolving credit facility may be increased by $100 million (the "increase option") to $260 million generally by 
mutual agreement of the Company, the lenders, the letter of credit issuers and the administrative agent named in the related 
credit agreement (the "Credit Agreement"), subject to certain customary conditions. The Credit Facility was used to refinance 
the Company's then-existing $100 million senior unsecured revolving credit facility (no amounts were outstanding as of May 
15, 2012) and its $150 million senior unsecured term loan (balance of $90.0 million as of May 15, 2012), both of which were 
scheduled  to  mature  on  April 4,  2013  (the  “Prior  Credit  Facility”),  and  for  general  corporate  purposes.    Quarterly  principal

Notes to Consolidated Financial Statements 

repayments of the Credit Facility term loan of $3.75 million per quarter began June 29, 2012 and end on March 28, 2013. The 
final $75.0 million payment is due on May 15, 2017.  As of September 29, 2012, the Company had term loan borrowings of 
$82.5 million outstanding under the Credit Facility, and the Company had $97.5 million of term loan borrowing outstanding 
under  the  Prior  Credit  Facility  as of  October 1, 2011.   There were  no revolving borrowings under either credit facility as of 
September 29, 2012 and October 1, 2011. 

The financial covenants (as defined under the Credit Facility) require that the Company maintain, as of each fiscal quarter end, 
a  maximum  total  leverage  ratio  and  a  minimum  interest  coverage  ratio.    As  of  September 29,  2012,  the  Company  was  in 
compliance  with  all  covenants  of  the  Credit  Facility.    Borrowings  under  the  Credit  Facility,  at  the  Company's  option,  bear 
interest at a defined base rate or the LIBOR rate plus, in each case, an applicable margin based upon the Company's leverage 
ratio as defined in the Credit Agreement.  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 1.0% or base rate plus 0%.  
As of September 29, 2012, the Company had a borrowing rate of LIBOR plus 1.13%.  The Company is also required to pay an 
annual commitment fee on the unused revolver credit commitment based on the Company's leverage ratio; the fee was 0.2% as 
of September 29, 2012.  

In connection with the Credit Facility, the Company incurred approximately $0.9 million in new debt issuance costs, which are 
being amortized over the five-year term of the Credit Facility.   

During  the  third  quarter  of  fiscal  2011,  the  Company  entered  into  a  Note  Purchase  Agreement  with  certain  institutional 
investors and issued $175 million in principal of 5.20% Senior Notes, due on June 15, 2018 (the “Notes”). The Company had 
$175  million  principal  of  Notes  outstanding  as  of  both  September 29,  2012  and  October 1,  2011.    The  Note  Purchase 
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  Note  Purchase 
Agreement.  As of September 29, 2012, the Company was in compliance with all such covenants. 

Cash paid for interest in fiscal 2012, 2011 and 2010 was $16.4 million, $8.6 million and $9.2 million, respectively.  

6. 

Derivatives and Fair Value Measurements 

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

The  Company’s  Malaysian  operations  have  entered  into  forward  exchange  contracts  on  a  rolling  basis  with  a  total  notional 
value of $54.1 million as of September 29, 2012. 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 $1.1 million asset as of 
September 29, 2012, and a $1.5 million liability as of October 1, 2011. 

The  Company  entered  into  three  interest  rate  swap  contracts  related  to  the  $150  million  in  term  loans  under  its  Prior  Credit 
Facility that had an initial total notional value of $150 million and mature on April 4, 2013. These interest rate swap contracts 
continued into the Credit Facility and pay the Company variable interest at the three month LIBOR rate, and the Company pays 
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 originally entered into to convert $150 million of the variable rate term 
loan  under  the  Prior  Credit  Facility  into  fixed  rate  debt.    Based  on  the  terms  of  the  interest  rate  swap  contracts  and  the 
underlying debt, these interest rate contracts were determined to be effective, and thus qualify as a cash flow hedge.  As such, 
any changes in the fair value of these interest rate swaps are recorded in “Accumulated other comprehensive income” on the 
accompanying Consolidated Balance Sheets until earnings are affected by the variability of cash flows.  The total fair value of 
these  interest  rate  swap  contracts  was  a  $1.7  million  liability  as  of  September 29,  2012  and  a  $5.2  million  liability  as  of 
October 1, 2011. As of September 29, 2012, the total remaining combined notional amount of the Company’s three interest rate 
swaps was $82.5 million. 

The Company’s Mexican operations were parties to forward exchange contracts all of which were settled as of the third quarter 
of fiscal 2012. The total fair value of these forward contracts was a $1.0 million liability as of October 1, 2011.

Notes to Consolidated Financial Statements 

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  the  Company’s  fourth  facility  in 
Malaysia;  these  contracts  were  settled  as  of  the  end  of  the  first  quarter  of  fiscal  2012.  The  total  fair  value  of  these  forward 
contracts was a $0.1 million liability as of October 1, 2011. 

During fiscal 2011, the Company entered into 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.    During  the  third 
quarter of fiscal 2011, when the fixed interest rate for the debt issuance was determined, all 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.

The Company recorded income tax expense of $29.1 million, $2.8 million and $0.9 million for fiscal 2012, 2011 and 2010, 
respectively.  The increase to the income tax expense recorded in fiscal 2012 as compared to fiscal 2011 and fiscal 2010 is the 
result of the Company recording an additional valuation allowance against the U.S. deferred tax assets based on the significant 
negative  evidence  of    the  Company's  U.S.  cumulative  loss  position  and  the  deterioration  of  its  forecasts  late  in  the  fourth 
quarter of fiscal 2012 for fiscal 2013, which has impacted forecasted profitability in the near term in the AMER region. Plexus 
believes  the  cumulative  losses  for  the  previous  three  fiscal  years  are  a  significant  factor  in  establishing  such  an  allowance 
coupled  with  the  lesser  weight  of  evidence  pertaining  to  longer  range  forecasts.    As  the  weight  given  to  the  positive  and 
negative evidence is proportionate with the extent to which the evidence may be objectively verified, it is generally difficult for 
positive evidence regarding projected future taxable income exclusive of reversing taxable temporary differences to outweigh 
objectively verifiable negative evidence of recent financial reporting losses. Accordingly, the Company, based on the weight of 
the  available  positive  and  negative  evidence,  established  an  additional  valuation  allowance  of  $20.6  million  ($22.8  million 
provision, offset by $2.2 million to other comprehensive income) on the U.S deferred tax assets as of September 29, 2012.   

The  components  of  the  net  deferred  income  tax  asset  as  of  September 29,  2012  and  October 1,  2011,  consisted  of  (in

As  discussed  above,  during  fiscal  2012  the  Company  established  a  full  valuation  allowance  of  $20.6  million  ($22.8  million 
provision, offset by $2.2 million to other comprehensive income, for a net deferred tax asset reduction of $20.6 million) against 
the U.S. net deferred assets.  In addition, during fiscal 2012 the Company added valuation allowances of $0.9 million and $0.4 
million  in  Germany  and  Romania,  respectively,  to  offset  the  increase  in  net  deferred  tax  assets  in  those  jurisdictions  which,

Plexus Corp. 
Notes to Consolidated Financial Statements 

more  likely  than  not,  will  not  be  realized.    In  fiscal  2011  and  fiscal  2010  the  Company  added  valuation  allowances  of  $0.3 
million and $0.2 million in the United Kingdom, respectively, and $0.9 million and $0.6 million in Romania, respectively.   

During the fiscal year ended September 29, 2012, tax legislation was adopted in various jurisdictions. None of these changes 
are expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows.  

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 2012, 
2011 and 2010, these subsidiaries generated income, which resulted in tax reductions of approximately $17.5 million ($0.50 per 
basic share), $21.7 million ($0.57 per basic share) and $23.0 million ($0.58 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  permanently  reinvested.    The  aggregate  undistributed  earnings  of  the 
Company’s  foreign  subsidiaries  for  which  a  deferred  income  tax  liability  has  not  been  recorded  was  approximately  $467.1 
million as of September 29, 2012. 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 September 29, 2012, the Company had approximately $78.9 million of state net operating loss carryforwards that expire 
between fiscal 2013 and 2032, which also have a full valuation allowance against them. 

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.  As of the end of fiscal 2012 there was a valuation allowance of $2.3 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.   

Cash paid for income taxes in fiscal 2012 and 2010 was $9.0 million and $3.5 million, respectively.  Cash refund for income 
taxes in fiscal 2011 was $2.2 million.  

The Company has approximately $7.6 million of uncertain tax benefits as of September 29, 2012. 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 $6.5 million and $6.3 million, respectively of the balance as of September 29, 2012, and October 1, 2011 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 $0.9 million, $0.7 million and $0.5 
million as of September 29, 2012, October 1, 2011 and October 2, 2010, 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 
September 29, 2012.

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.  The Company is currently under examination by taxing authorities in the U.S. 
for fiscal years 2008 through 2010 and is not undergoing any tax examinations in any of its major foreign jurisdictions. The 
U.S. examination may be resolved within the next twelve months, but at this time it is not possible to estimate the amount of 
the effects of any changes to the Company's previously recorded uncertain tax positions.   

The  Company  files  income  tax  returns,  including  returns  for  its  subsidiaries,  with  federal,  state,  local  and  foreign  taxing 
jurisdictions. The following tax years remain subject to examination by the respective major tax jurisdictions:

In fiscal 2012, 2011 and 2010, stock options and stock-settled stock appreciation rights (‘SARs”) to purchase approximately 
1.4 million, 1.3 million and 1.2 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.

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 2012, 2011 and 2010 was approximately $14.2 million, $12.8 million and 
$11.8 million, respectively. Renewal and purchase options are available on certain of these leases.

Benefit Plans 

401(k) Savings Plan: The Company’s 401(k) Retirement 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  2012,  2011  and  2010 
totaled $6.9 million, $5.8 million and $4.9 million, respectively. 

Stock-based  Compensation  Plans:  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 exercise, expiration or forfeiture. 

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.  

Options and SAs issued to the members of the Board of Directors in fiscal 2012, 2011 and 2010 vested immediately on the date 
of grant.  

In fiscal 2012, under the 2008 Plan, the Company granted options to purchase 0.3 million shares of the Company’s common 
stock and 0.2 million stock-settled SARs. Additionally, the Committee made awards of RSUs for 0.3 million shares of common 
stock, and the Committee granted SAs for 6.0 thousand shares of common stock. 

In fiscal 2011, under the 2008 Plan, the Company granted options to purchase 0.3 million shares of the Company’s common 
stock and 0.3 million stock-settled SARs. Additionally, the Committee made awards of RSUs for 0.1 million shares of common 
stock, and the Committee granted SAs for 10.0 thousand shares of common stock. 

In fiscal 2010, under the 2008 Plan, the Company granted options to purchase 0.3 million shares of the Company’s common 
stock and 0.3 million stock-settled SARs. Additionally, the Committee made awards of RSUs for 0.1 million shares of common 

59 

 
 
 
 
 
 
 
Plexus Corp. 
Notes to Consolidated Financial Statements 

stock and long-term cash awards that totaled $0.9 million, and the Committee granted SAs for 16.0 thousand shares of common 
stock. 

The  Company  recognized  $12.5  million,  $11.0  million,  and  $9.5  million  of  compensation  expense  associated  with  stock 
options, SARs, RSUs and SAs for fiscal 2012, 2011 and 2010, respectively. The related deferred tax benefit recognized was 
$0.0 million, $3.7 million, and $3.2 million for fiscal 2012, 2011 and 2010, 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 SARs 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 granted for fiscal 2012, 2011 and 2010 were $13.13, $13.40 and 
$14.25, 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:

The fair value of options and SARs vested for fiscal 2012, 2011 and 2010 were $4.3 million, $3.6 million and $3.1 million, 
respectively. 

For fiscal 2012, 2011 and 2010, the total intrinsic value of options and SARs exercised was $7.6 million, $6.5 million and $8.5 
million, respectively. 

As of September 29, 2012, there was $6.3 million of unrecognized compensation cost related to non-vested options and SARs 
that is expected to be recognized over a weighted average period of 1.22 years.

The Company uses the fair value at the date of grant to value RSUs and SAs. The fair values of RSUs and SAs that vested for 
fiscal  2012,  2011  and  2010  were  $1.4  million,  $0.6  million  and  $0.5  million,  respectively.    There  were  193,684  RSUs  and 
6,000 SAs that vested during the fiscal year ended September 29, 2012.  There were 88,112 RSUs and 10,000 SAs that vested 
during the fiscal year ended October 1, 2011.  There were 16,000 SAs that vested during the fiscal year ended October 2, 2010; 
there were no RSUs that vested in fiscal 2010.  

As of September 29, 2012, there was $9.2 million of unrecognized compensation cost related to RSUs that is expected to be 
recognized over a weighted average period of 2.07 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  these  former  executives,  or  their 
designated  beneficiaries  upon  such  executives’  deaths,  certain  amounts  annually  for  the  first  15  years  subsequent  to  their 
retirements.

Plexus Corp. 
Notes to Consolidated Financial Statements 

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  2012,  2011  and  2010,  the  Company  made  contributions  to  the 
participants’ SERP accounts in the amount of $0.4 million, $0.3 million and $0.2 million, respectively. 

As  of  September 29,  2012  and  October 1,  2011,  the  SERP  assets  held  in  the  Trust  totaled  $7.7  million  and  $6.2  million, 
respectively, and the related liability to the participants totaled approximately $4.8 million and $3.9 million as of September 29, 
2012 and October 1, 2011, 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 

Plexus  was  notified  in  April  2009  by  U.S.  Customs  and  Border  Protection  (“CBP”)  of  its  intention  to  conduct  a  customary 
Focused Assessment of the Company's import activities during fiscal 2008 and of its 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. In August 2012, CBP issued its final determination of duties and fees owed by Plexus. 
The Company paid into a CBP-maintained escrow account the duties and fees claimed by CBP, pending a ruling from CBP 
Headquarters  which  could  reduce  the  duties  and  fees  owed  by  Plexus.  Plexus  has  implemented  improved  processes  and 
procedures and has reviewed these corrective measures with CBP.  The Company 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.  The  accrual  has  been  reduced  to  reflect the  Company's  payment  into  the  CBP  escrow  account.   At  this 
time, Plexus does 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 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. 

In  fiscal  2010,  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. 

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 

62 

 
  
 
  
 
Plexus Corp. 
Notes to Consolidated Financial Statements 

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.

Due to the Company being a contract manufacturer which produces unique products and services related to each contract, it is 
impracticable to provide revenue by product/service information.  

Long-lived assets as of September 29, 2012 and October 1, 2011 exclude other long-term assets and deferred income tax assets 
which totaled $46.5 million and $48.1 million, respectively. 

The percentages of net sales to customers representing 10 percent or more of total net sales for fiscal 2012, 2011 and 2010 were 
as follows: 

Juniper Networks, Inc. (“Juniper”)

2012 
16% 

2011 
17% 

2010 
16% 

For our significant customers, we generally manufacture products in more than one location. For example, net sales to Juniper, 
our largest customer, occur in the AMER and APAC reportable segments.  On November 5, 2012, Juniper notified us that they 
will disengage with Plexus.  The specific timing of the transition of the Juniper business from Plexus is not known at this time, 
although  it  is  currently  expected  to  occur  by  the  end  of  fiscal  2013.   The  Company  is  currently  evaluating  the  financial 
statement impact, if any, of the recent notification.

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. 

Below is a table summarizing the activity related to the Company’s limited warranty liability for the fiscal years 2012 and 2011 
(in thousands):

Revision of Prior Period Financial Statements

In the second quarter of fiscal 2012, the Company identified prior period errors in its consolidated financial statements related
to the Consolidated Balance Sheets and Consolidated Statements of Cash Flows classification of upfront payments made for 
land use rights. Specifically, the Company had historically accounted for the upfront payments for the land use rights as capital 
leases  within  property,  plant  and  equipment  and  as  investing  activities  in  the  Consolidated  Statements  of  Cash  Flows.  The 
Company has determined that the upfront payments made for land use rights should have been reflected as an operating lease 
within  other  long-term  assets  on  the  Consolidated  Balance  Sheets  and  as  operating  activities  within  the  Consolidated 
Statements  of  Cash  Flows.  There  was  no  impact  of  the  error  corrections  on  the  Consolidated  Statements  of  Operations.  In 
evaluating whether the Company’s previously issued consolidated financial statements were materially misstated, the Company 
considered the guidance in Accounting Standard Codification (ASC) Topic 250, Accounting Changes and Error Corrections, 
ASC  Topic  250-10-S99-1,  Assessing  Materiality,  and  ASC  Topic  250-10-S99-2,  Considering  the  Effects  of  Prior  Year 
Misstatements  when Quantifying  Misstatements  in  Current  Year  Financial  Statements.  The  Company  concluded  these  errors 
were not material individually or in the aggregate to any of the prior reporting periods. The impact of these corrections to the
applicable  prior  periods  are  reflected  in  the  financial  information  and  notes  herein  and  will  be  reflected  in  future  filings 
containing affected financial information. The impact of these revisions on the financial statements included in the Company’s 
2011 Annual Report on Form 10-K and previously filed 2012 and 2011 Forms 10-Q is described below. In addition, footnotes 
impacted by the above error will also be revised in future filings.

Notes to Consolidated Financial Statements 

Revisions to the Consolidated Balance Sheets reflect a decrease in property, plant and equipment and an increase to other long-
term assets in the amounts of $17.6 million, $17.7 million, and $14.8 million as of December 31, 2011, October 1, 2011, and 
October 2, 2010, respectively. 

During the fourth quarter of fiscal 2010 and the first quarter of fiscal 2011, the Company made upfront payments for land use 
rights  in  the  amount  of  $9.6  million  and  $3.2  million,  respectively.  These  payments  were  classified  as  capital  expenditures 
within investing activities in the Consolidated Statements of Cash Flows for fiscal 2010 and 2011 and each quarterly period in 
fiscal  2011.  The  classification  of  these  payments  has  been  corrected  to  properly  reflect  these  amounts  as  operating  cash 
outflows rather than investing cash outflows in the financial information included herein and will be corrected in the relevant 
periods in future filings. There will also be inconsequential revisions to depreciation and change in prepaid expense and other

Subsequent Event 

On November 5, 2012, Juniper, the Company's largest customer, notified the Company that it will disengage from Plexus.  In 
fiscal  2012,  Juniper's  sales  approximated  16  percent  of  consolidated  net  sales.  Sales  to  Juniper  are  primarily  made  from  the 
Company's  AMER  and  APAC  segments.   The  specific  timing  of  the  transition  of  the  Juniper  business  from  Plexus  is  not 
known at this time, although it is currently expected to occur by the end of fiscal 2013.  The Company is currently evaluating 
the financial, operational and other impacts of the disengagement.
