PROXY STATEMENT

General Information About the Meeting

General
The enclosed Proxy is solicited on behalf of the Board of Directors (the ‘‘Board’’) of Coherent, Inc. for use at the Annual Meeting of
Stockholders (the ‘‘Annual Meeting’’ or ‘‘meeting’’) to be held at 8:00 a.m., local time, on March 2, 2017 at the Hyatt Regency
Santa Clara, 5101 Great America Parkway, Santa Clara, California 95054, and at any adjournment(s) thereof, for the purposes
set forth herein and in the accompanying Notice of Annual Meeting of Stockholders. Our telephone number is (408) 764-4000.
These proxy solicitation materials were first mailed on or about January 26, 2017 to all stockholders entitled to vote at the Annual
Meeting.

Who May Vote at the Meeting?
You are entitled to vote at the Annual Meeting if our records
show that you held your shares as of the close of business on
our record date, January 19, 2017 (the ‘‘Record Date’’). On the
Record Date, 24,553,828 shares of our common stock, $0.01
par value, were issued and outstanding.

What Does Each Share of Common
Stock I Own Represent?
On all matters, each share has one vote, unless, with respect
to  Proposal  One  regarding 
the  election  of  directors,
cumulative voting is in effect. See ‘‘Election of Directors—Vote
Required’’  for  a  description  of  cumulative  voting  rights  with
respect to the election of directors.

How Does a Stockholder Vote?
Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy to ensure your vote is counted. If you are
entitled to vote, you may do so as follows:

• Through your broker: If your shares are held through a broker, bank or other nominee (commonly referred to as held in
‘‘street name’’), you will receive instructions from them that you must follow to have your shares voted. If you want to vote in
person, you will need to obtain a legal proxy from your broker, bank or other nominee and bring it to the meeting.

• In person: Attend the Annual Meeting and, if you request, we will give you a ballot at the time of voting. If you have previously
submitted a proxy card, you must notify us at the Annual Meeting that you intend to cancel your prior proxy and vote by ballot at
the meeting.

• Returning a Proxy Card: Simply complete, sign and date the enclosed proxy card and return it promptly in the envelope
provided. If your signed proxy card is received before the Annual Meeting, the designated proxies will vote your shares as you
direct.

• Using the Telephone: Dial toll-free 1-800-690-6903 using a touch-tone phone and follow the recorded instructions. You will

be asked to provide the control number from the enclosed proxy card.

• Through the  Internet: Go to www.proxyvote.com to complete  an electronic proxy card. You will  be  asked to  provide  the

control number from the enclosed proxy card.

For telephone or Internet use, your vote must be received by 11:59 P.M. Eastern Time on March 1, 2017 to be counted.

If you return a signed and dated proxy card without marking any voting directions, your shares will be voted ‘‘for’’ the election of
all seven nominees for director, ‘‘for’’ Proposals Two and Three and for ‘‘Abstain’’ with respect to Proposal Four.

General Information

Matters to be Presented at the Meeting
We are not aware of any matters to be presented at the meeting other than those described in this proxy statement. If any other
matter is properly presented at the Annual Meeting, your proxy holders (one of the individuals named on your proxy card) will vote
your shares in their discretion. The cost of this solicitation will be borne by us. We may reimburse brokerage firms and other
persons representing beneficial owners of shares for their expenses in forwarding solicitation material to such beneficial owners.
In addition, proxies may be solicited by certain of our directors, officers and regular employees, without additional compensation,
personally or by telephone, e-mail or facsimile.

Revoking Your Proxy
If you hold your shares in street name, you must follow the instructions of your broker, bank or other nominee to revoke your voting
instructions. If you are a holder of record and wish to revoke your proxy instructions, you must (i) advise the Corporate Secretary
in writing at our principal executive offices at 5100 Patrick Henry Dr., Santa Clara, California 95054 before the proxies vote your
shares at the meeting, (ii) timely deliver later-dated proxy instructions or (iii) attend the meeting and vote your shares in person.

Attendance at the Annual Meeting

All stockholders of record as of the Record Date may attend
the  Annual  Meeting.  Please  note  that  cameras,  recording
devices and similar electronic devices will not be permitted at
the Annual Meeting. No items will be allowed into the Annual
Meeting  that  might  pose  a  concern  for  the  safety  of  those
attending. Additionally, to attend the meeting you will need to
bring identification and proof sufficient to us that you were a

stockholder of record as of the Record Date or that you are a
duly authorized representative of a stockholder of record as of
the Record Date. For directions to attend the Annual Meeting
or  other  questions,  please  contact  Investor  Relations  by
telephone  at  (408)  764-4110  no  later  than  noon  (California
time) on March 1, 2017.

Quorum; Abstentions; Broker
Non-Votes

Our bylaws provide that stockholders holding a majority of the
shares of common stock issued and outstanding and entitled
to vote on the Record Date constitute a quorum at meetings of
stockholders.  Votes  will  be  counted  by  the  inspector  of
election appointed for the Annual Meeting, who will separately
count  ‘‘For’’  and  ‘‘Against’’  votes,  abstentions  and  broker
non-votes,  and  with  respect  to  Proposal  Four,  votes  for
‘‘1 year’’, ‘‘2 years’’ and ‘‘3 years.’’

A ‘‘broker non-vote’’ occurs when a nominee holding shares
for  a  beneficial  owner  does  not  vote  because  the  nominee
does not have discretionary voting power with respect to the

proposal and has not received instructions with respect to the
proposal  from  the  beneficial  owner.  Abstentions  will  not  be
taken into account in determining the outcome of the election
of  directors  and  will  have  no  effect  on  the  outcome  of
Proposals  Two,  Three  and  Four.  We  intend  to  separately
report  abstentions  and  our  Compensation  and  H.R.
Committee  will  generally  view  abstentions  as  neutral  when
considering the results of Proposal Three. Broker non-votes
represented  by  submitted  proxies  will  not  be  taken  into
account in determining the outcome of any proposal.

Director Independence
The Board has determined that, with the exception of Mr. Ambroseo, all of its current members and all of the nominees for director
are ‘‘independent directors’’ as that term is defined in the listing rules of the Nasdaq Stock Market.

Board Meetings and Committees

The Board held a total of five (5) formal meetings and acted
twice  by  unanimous  written  consent  during  fiscal  2016.
Additionally,  from  time  to  time  between  formal  meetings,
members  of  the  Board  participate  in  update  or  status
telephone calls and briefings, which are not included in these
totals.  During  fiscal  2016,  the  Board  had  three  standing
committees:  the  Audit  Committee;  the  Compensation  and
H.R.  Committee;  and  the  Governance  and  Nominating
Committee. From time to time, the Board may create, and has
in  the  past  created,  limited  ad  hoc  committees,  service  on
which does not provide additional compensation. No director
serving  during  fiscal  2016  attended  fewer  than  75%  of  the
aggregate of all meetings of the Board and the committees of
the Board upon which such director served.

‘‘independent’’ as defined under the listing rules of the Nasdaq
Stock Market. The Compensation and H.R. Committee held
four  (4)  meetings  during  fiscal  2016  and  acted  once  by
unanimous  written  consent.  The  Compensation  and  H.R.
Committee,  among  other  things,  reviews  and  approves  our
executive  compensation  policies  and  programs,  and  makes
equity grants to our employees, including officers, pursuant to
our  equity  plan.  This  committee  has  the  sole  authority
delegated to it by the Board to make employee equity grants,
which are done at a meeting rather than by written consent.
For  additional  information  about  the  committee’s  processes
and  procedures  for  the  consideration  and  determination  of
executive compensation, see ‘‘Compensation Discussion and
Analysis.’’

Audit Committee
The  Audit  Committee  consists  of  directors  James  (Chair),
Rogerson,  and  Skaggs.  The  Audit  Committee  held  twelve
(12) meetings during fiscal 2016. The Board has determined
that  directors  James,  Rogerson  and  Skaggs  are  ‘‘audit
committee  financial  experts’’  as  that  term  is  defined  in  the
rules of the SEC. Among other things, the Audit Committee
has  the  sole  authority  for  appointing  and  supervising  our
independent registered public accounting firm and is primarily
responsible  for  approving  the  services  performed  by  our
independent  registered  public  accounting 
for
reviewing  and  evaluating  our  accounting  principles  and  our
system of internal accounting controls.

Governance and Nominating Committee
The  Governance  and  Nominating  Committee  consists  of
directors  Rogerson  (Chair),  James  and  Krause.  The
Governance  and  Nominating  Committee  held 
three
(3)  meetings  during  fiscal  2016.  The  Governance  and
Nominating Committee, among other things, assists the Board
by  making  recommendations  to  the  Board  on  matters
concerning  director  nominations  and  elections,  board
committees  and  corporate  governance,  allocation  of  risk
oversight  amongst  the  Board  and  its  committees  and
compensation  for  directors.  For  fiscal  2016,  the  committee
retained an independent compensation consultant to advise it
on compensation for service on the Board.

The Compensation and H.R. Committee of the Board consists
of directors Vij (Chair), Flatley and Krause. As noted above, all

Attendance at Annual Meeting of Stockholders by the Members of the Board of
Directors
All directors are encouraged, but not required, to attend our annual meeting of stockholders. At our annual meeting held on
February 26, 2016, all members of the Board attended in person.

10

Process for Stockholders to
Recommend Candidates for Election
to the Board of Directors

The  Governance  and  Nominating  Committee  will  consider
nominees  properly 
recommended  by  stockholders.  A
stockholder  that  desires  to  recommend  a  candidate  for
election  to  the  Board  must  direct  the  recommendation  in
writing  to  us  at  our  principal  executive  offices  (Attention:
Corporate Secretary) and must include the candidate’s name,
age,  home  and  business  contact  information,  principal
occupation or employment, the number of shares beneficially
owned  by  the  nominee  and  the  stockholder  making  the
recommendation,  whether  any  hedging  transactions  have
been  entered  into  by  the  nominee  or  on  his  or  her  behalf,
information  regarding  any  arrangements  or  understandings
between  the  nominee  and  the  stockholder  nominating  the
nominee  or  any  other  persons  relating  to  the  nomination,  a
written  statement  by  the  nominee  acknowledging  that  the
nominee  will  owe  a  fiduciary  duty  to  Coherent  if  elected,  a
written  statement  of  the  nominee  that  such  nominee,  if
elected, intends to tender, promptly following such nominee’s
election  or  re-election,  an  irrevocable  resignation  effective
upon such nominee’s failure to receive the required vote for
re-election at the next meeting at which such nominee would
face re-election and upon acceptance of such resignation by
the  Board  in  accordance  with  Coherent’s  guidelines  or
policies,  and  any  other  information  required  to  be  disclosed
about the nominee if proxies were to be solicited to elect the
nominee as a director.

For  a  stockholder  recommendation  to  be  considered  by  the
Governance  and  Nominating  Committee  as  a  potential
candidate at a meeting of stockholders, nominations must be
received on or before the deadline for receipt of stockholder
proposals  for  such  meeting.  In  the  event  a  stockholder
decides  to  nominate  a  candidate  for  director  and  solicits
proxies for such candidate, the stockholder will need to follow
the rules set forth by the SEC and in our bylaws. See ‘‘General
Information  About  the  Meeting-Deadline  for  Receipt  of
Stockholder Proposals.’’

The  Governance  and  Nominating  Committee’s  criteria  and
process  for  evaluating  and  identifying  the  candidates  that  it
approves as director nominees are as follows:

• the  Governance  and  Nominating  Committee  regularly
reviews the current composition and size of the Board;

• the  Governance  and  Nominating  Committee  reviews  the
qualifications  of  any  candidates  who  have  been  properly
those
recommended  by  a  stockholder,  as  well  as 

11

Proposal One Election of Directors

in 

candidates  who  have  been  identified  by  management,
individual members of the Board or, if the Governance and
Nominating  Committee  determines,  a  search  firm.  Such
review  may,

Committee’s  discretion,

Committee  or  may  also  include  discussions  with  persons
familiar with the candidate, an interview with the candidate
or other actions that the committee deems proper;

include  a 

• the Governance and Nominating Committee evaluates the
performance  of  the  Board  as  a  whole  and  evaluates  the
qualifications of individual members of the Board eligible for
re-election at the annual meeting of stockholders;

• the Governance and Nominating Committee considers the
suitability of each candidate, including the current members
of the Board, in light of the current size and composition of
the Board. Except as may be required by rules promulgated
by  the  Nasdaq  Stock  Market  or  the  SEC,  it  is  the  current
belief  of  the  Governance  and  Nominating  Committee  that
there are no specific, minimum qualifications that must be
met by any candidate for the Board, nor are there specific
qualities or skills that are necessary for one or more of the
members  of  the  Board  to  possess.  In  evaluating  the
qualifications  of  the  candidates,  the  Governance  and
Nominating Committee considers many factors, including,
issues  of  character, 
independence,  age,
judgment, 
expertise,  diversity  of  experience,  length  of  service,  other
commitments and the like. While Coherent does not have a
formal policy with regard to the consideration of diversity in
identifying director nominees, as noted above, diversity of
experience  is  one  of  many  factors  that  the  committee
considers;

these 

• the Governance and Nominating Committee evaluates such
factors, among others, and does not assign any particular
weighting  or  priority 
factors.  The
to  any  of 
Governance  and  Nominating  Committee  considers  each
individual candidate in the context of the current perceived
needs of the Board as a whole. While the Governance and
Nominating  Committee  has  not  established  specific
minimum  qualifications 
the
committee  believes  that  candidates  and  nominees  must
reflect  a  Board  that  is  comprised  of  directors  who  (i)  are
predominantly  independent,  (ii)  are  of  high  integrity,
(iii)  have  qualifications  that  will  increase  the  overall
effectiveness of the Board, and (iv) meet other requirements

for  director  candidates, 

Proposal One Election of Directors

as  may  be  required  by  applicable  rules,  such  as  financial
literacy  or 
to  audit
committee members;

financial  expertise  with  respect 

• in  evaluating  and  identifying  candidates,  the  Governance
and Nominating Committee has the authority to retain and
terminate any third party search firm that is used to identify
director  candidates  and  has  the  authority  to  approve  the
fees and retention terms of any search firm; and

• after such review and consideration, the Governance and
Nominating  Committee  recommends  the  slate  of  director
nominees to the full Board for its approval.

The Governance and Nominating Committee will endeavor to
notify, or cause to be notified, all director candidates, including

those  recommended  by  a  stockholder,  of  its  decision  as  to
whether to nominate such individual for election to the Board.

Our  corporate  governance  guidelines  require  that  upon  a
member  of  the  Board  turning  72  years  old,  he  or  she  shall
submit  a  conditional  resignation  to  the  Governance  and
Nominating  Committee  effective  upon  the  next  annual
meeting  of  stockholders.  The  committee  then  determines
whether  to  recommend  that  the  Board  accept  of  such
resignation. Mr. Krause has so notified the committee, which
determined  that  it  was  not  in  the  best  interest  of  the
Company’s stockholders to accept such resignation and has
included  Mr.  Krause  in  the  slate  for  this  year’s  election  of
directors.

Majority Voting and Conditional
Resignations from the Board of
Directors

the 

recommendation  of 

Upon 
the  Governance  and
Nominating Committee the Board of Directors amended our
bylaws,  effective  December  1,  2013,  to  change  the  voting
standard for the election of directors that are not Contested
Elections (as defined below) from a plurality to a majority of the
votes cast. A majority of the votes cast means the number of
votes cast ‘‘for’’ a director’s election exceeds the number of
votes cast against that director’s election (with ‘‘abstentions’’
and ‘‘broker non-votes’’ not counted as a vote cast either ‘‘for’’
or ‘‘against’’ that director’s election). However, if the number of
nominees  exceeds  the  number  of  directors  to  be  elected  (a
‘‘Contested  Election’’),  the  directors  shall  be  elected  by  a
plurality of the votes cast.

Stockholder Communication with the
Board of Directors

While  the  Board  believes  that  management  speaks  for
Coherent, the Board encourages direct communication from
stockholders. Accordingly, any stockholder may contact any
member of our Board of Directors individually or as a group by
writing by mail to our principal executive offices (c/o Corporate
Secretary) at 5100 Patrick Henry Dr., Santa Clara, CA 95054.

In connection with the amendment to the Bylaws establishing
a  majority  vote  standard  for  the  election  of  directors  in
elections  that  are  not  Contested  Elections,  the  Board  also
adopted a director election policy to (i) establish procedures
under  which  any  incumbent  director  who  fails  to  receive  a
majority of the votes cast in an election that is not a Contested
Election shall tender his or her resignation to the Governance
and Nominating Committee for consideration; and (ii) provide
that  the  Governance  and  Nominating  Committee  will  make
recommendations  to  the  Board  regarding  the  actions  to  be
taken with respect to all such offers to resign. The Board shall
act on the resignation within 90 days following certification of
the  election  results.  In  the  event  that  the  Board  does  not
accept such resignation, then such director shall continue to
serve until such time as his or her successor is elected.

Any stockholder may report to us any complaints or comments
regarding accounting, internal accounting controls, or auditing
matters. Any stockholder who wishes to so contact us should
send  such  complaints  or  comments  to  the  Audit  Committee
c/o Corporate Secretary, at our principal executive offices.

Any stockholder communications that the Board receives will
first  go  to  our  Corporate  Secretary,  who  will  log  the  date  of

12

Proposal One Election of Directors

receipt  of  the  communication  as  well  as  the  identity  and
contact  information  of  the  correspondent  in  our  stockholder
communications log.

Our  Corporate  Secretary  will  review,  summarize  and,  if
appropriate,  investigate  the  complaint  under  the  direction  of
the appropriate committee of the Board in a timely manner. In
the case of accounting or auditing related matters, a member

of the Audit Committee, or the Audit Committee as a whole,
will  then  review  the  summary  of  the  communication,  the
results of the investigation, if any, and, if appropriate, the draft
response. The summary and response will be in the form of a
the  stockholder
memo,  which  will  become  part  of 
communications  log  that  the  Corporate  Secretary  maintains
with respect to all stockholder communications.

Independent Chair and Board Leadership
Our  Board  leadership  structure  consists  of  an  independent  Chairman,  who  is  elected  by  the  independent  directors,  and
independent  committee  chairs.  We  separate  the  positions  of  Chief  Executive  Officer  and  Chairman  in  recognition  of  the
differences between the two roles. The Board believes this structure provides independent Board leadership and engagement.

Given that our Chairman is an independent director, the Board does not feel the need for a separate ‘‘lead independent director,’’
as our independent Chairman performs that function. The Board takes its independence seriously and reinforces this standard
with six of its seven members, 87%, being independent.

The Role of the Board and its
Committees in Risk Oversight

The  Board  oversees  Coherent’s 
risk  profile  and
management’s  processes  for  assessing  and  managing  risk,
both  as  a  Board  and  through  its  committees,  with  our
Governance  and  Nominating  Committee  delegated 
the
responsibility for assigning oversight responsibilities to each
committee  and  the  Board  as  a  whole.  Our  senior  executive
team  provides  regular  updates  to  the  Board  and  each
committee  regarding  our  strategies  and  objectives  and  the
risks inherent with them.

those 

related 

Each  regular  meeting  of  the  Board  includes  a  discussion  of
risks related to the Company’s financial results and operations
and  each  committee  schedules  risk-related  presentations
regularly throughout the year. In addition our directors have
access to our management to discuss any matters of interest,
including 
risk.  Those  members  of
to 
management most knowledgeable of the issues attend Board
and committee meetings to provide additional insight on the
matters being discussed, including risk exposures. Our Chief
Financial Officer and General Counsel both report directly to
our Chief Executive Officer, providing him with further visibility
to our risk profile. A Vice President, Finance is the designated
officer  overseeing  our  enterprise  risk  management  program
and  works  closely  with  both  our  Chief  Financial  Officer  and
General Counsel on these matters.

These regular meetings also provide our Board members the
opportunity  to  discuss  issues  of  concern  directly  with
management.  In  general  the  Board  and  its  committees
oversee the following risk categories:

• the  Board  generally  oversees  the  Company’s  overall
enterprise  risk  management  process  and  specifically  with
regards to the areas of strategy, mergers and acquisitions,
communications and operations;

• the  Audit  Committee  generally  oversees  risks  primarily
related  to  financial  controls,  IT,  accounting,  tax,  treasury,
capital, legal, regulatory and compliance;

• the Compensation and H.R. Committee generally oversees
our compensation programs so that they do not incentivize
excessive  risk  taking  as  well  as  overseeing  human
resources related risks; and

• the Governance and Nominating Committee oversees the
assignment of risk oversight categories by each particular
committee  and/or  the  Board  as  a  whole  as  well  as  those
risks  related  to  compensation  of  members  of  the  Board,
succession  planning  for  the  Board  and  Chief  Executive
Officer.

Annually, management presents an assessment of the risks
associated  with  the  Company’s  compensation  plans.  The

13

Proposal One Election of Directors

the
Compensation  and  H.R.  Committee  agreed  with 
conclusion from the winter of calendar 2016 presentation that
the  risks  were  within  our  ability  to  effectively  monitor  and

manage and that these risks are not reasonably likely to have
a material adverse effect on the Company.

Additional Governance Matters

The Board of Directors (acting on the recommendation of the
Governance  and  Nominating  Committee)  has  approved  the
Company’s Corporate Governance Guidelines, which include,
among  other  items  (in  addition  to  those  items  described
elsewhere in this proxy):

• At  each  regular  meeting  of  the  Board  the  independent
directors  also  meet  in  executive  session  without  the
presence of management;

• To avoid ‘‘over-boarding’’ we maintain the following limits on

service on other boards:

• CEO—No  more  than  one  (1)  other  public  company
board  of  directors  in  addition  to  the  Company  (note,
however,  that  Mr.  Ambroseo  does  not  serve  on  any
public company boards other than ours);

• Independent  Directors—No  more  than  four  (4)  other
public  company  board  of  directors  in  addition  to  the
Company;

• Audit  Committee  members—No  more  than  three
(3) other public company audit committees in addition
to the Company;

• Each  independent  member  of  the  Board  must  within  five
years of initial appointment acquire and thereafter maintain
a  minimum  value  of  Company  stock  equal  to  three  times
such director’s annual Board cash retainer (exclusive of any
cash retainer for service as Chair or committee service);

• The  Board  is  responsible  for  reviewing  the  Company’s
succession planning and senior management development
on an annual basis;

• The  Board  maintains  an  age-based  term  limit  of  72
(provided, that the Governance and Nominating Committee
maintains the flexibility to not apply such limit on a facts and
circumstances basis).

Fiscal 2016 Director Compensation

The  Governance  and  Nominating  Committee  annually
reviews  Board  and  committee  compensation  with 
the
assistance of an independent compensation consultant, which
for  fiscal  2016  was  Compensia.  Compensia  is  separately
compensated  for  this  work  from  the  work  it  does  as  the

Compensation and H.R. Committee’s independent consultant
for executive compensation. As noted elsewhere in this proxy
statement, Compensia has not provided any other service for
the  Company  other  than  as  directed  by  a  committee  of  the
Board.

Vote Required

Every  stockholder  voting  for  the  election  of  directors  may
cumulate such stockholder’s votes and give one candidate a
number of votes equal to the number of directors to be elected
multiplied by the number of votes to which the stockholder’s
shares are entitled. Alternatively, a stockholder may distribute
his  or  her  votes  on  the  same  principle  among  as  many
candidates  as  the  stockholder  thinks  fit,  provided  that  votes
cannot be cast for more than seven (7) candidates. However,
no  stockholder  will  be  entitled  to  cumulate  votes  for  a
candidate unless (i) such candidate’s name has been properly
placed in nomination for election at the Annual Meeting prior to
the voting and (ii) the stockholder, or any other stockholder,
has  given  notice  at  the  meeting  prior  to  the  voting  of  the
intention  to  cumulate  the  stockholder’s  votes.  If  cumulative
voting occurs at the meeting and you do not specify how to
distribute  your  votes,  your  proxy  holders  (the  individuals

named  on  your  proxy  card)  will  cumulate  votes  in  such  a
manner as will ensure the election of as many of the nominees
listed  above  as  possible,  and  the  specific  nominees  to  be
voted for will be determined by the proxy holders.

If a quorum is present, each of the seven (7) nominees who
receives  more  ‘‘FOR’’  votes  than  ‘‘AGAINST’’  votes  will  be
elected.

Recommendation
The  Board  recommends  that  Stockholders  vote  ‘‘FOR’’
the seven nominees presented herein.

PROPOSAL TWO
RATIFICATION OF THE APPOINTMENT OF
DELOITTE & TOUCHE LLP AS INDEPENDENT
REGISTERED PUBLIC ACCOUNTING FIRM

The  Audit  Committee  of  the  Board  has  selected  Deloitte  &
Touche  LLP,  an  independent  registered  public  accounting
firm, to audit our financial statements for the fiscal year ending
September 30, 2017, and recommends that stockholders vote
for  ratification  of  such  appointment.  Deloitte  &  Touche  LLP
has  audited  our  financial  statements  since  the  fiscal  year
ended  September  25,  1976.  Although 
ratification  by
stockholders is not required by law, the Audit Committee has
determined  that  it  is  desirable  to  request  ratification  of  this
selection by the stockholders as a matter of good corporate
practice. Notwithstanding its selection, the Audit Committee,
in  its  discretion,  may  appoint  a  new  independent  registered
public accounting firm at any time during the year if the Audit

Committee believes that such a change would be in the best
interest of Coherent and its stockholders. If the stockholders
do not ratify the appointment of Deloitte & Touche LLP, the
Audit  Committee  may  reconsider  its  selection.  The  Audit
Committee  selected  Deloitte  &  Touche  LLP  to  audit  our
financial statements for the fiscal year ended October 1, 2016,
which was ratified by our stockholders.

Representatives of Deloitte & Touche LLP are expected to be
present at the meeting and will be afforded the opportunity to
make a statement if they desire to do so. The representatives
of Deloitte & Touche LLP are also expected to be available to
respond to appropriate questions.

PROPOSAL THREE
APPROVAL ON A NON-BINDING, ADVISORY BASIS,
OF OUR NAMED EXECUTIVE OFFICER
COMPENSATION

At  our  Annual  Meeting  in  March  2011,  our  stockholders
indicated that they would like to have an annual advisory vote
on  executive  compensation.  Accordingly,  our  Board  of
Directors  proposes 
that  stockholders  provide  advisory
(non-binding)  approval  of  the  compensation  of  our  named
executive officers, as disclosed pursuant to the compensation
disclosure  rules  of  the  SEC,  including  the  Compensation
the  Fiscal  2016  Summary
Discussion  and  Analysis, 
Compensation Table and related tables and disclosure.

As described in our Compensation Discussion and Analysis,
we  have  adopted  an  executive  compensation  philosophy
designed  to  provide  alignment  between  executive  pay  and
performance and to focus executives on making decisions that
enhance our stockholder value in both the short and long term.
Executives  are  compensated  in  a  manner  consistent  with
Coherent’s  strategy,  competitive  practices,  stockholder
interest  alignment,  and  evolving  compensation  governance
standards.

Recommendation
The  Board  of  Directors  unanimously  recommends  that
Stockholders vote ‘‘FOR’’ the approval, on a non-binding,
advisory  basis  of  our  named  executive  officer
compensation disclosed in this proxy statement.

Vote Required
Under  our  bylaws  the  affirmative  vote  of  the  holders  of  a
majority  of  the  votes  cast  is  required  to  approve  the
compensation  of  our  named  executive  officers  disclosed  in
this  proxy  statement.  The  vote  is  an  advisory  vote,  and
therefore  not  binding.  Our  Board  of  Directors  values  the
opinions  of  our  stockholders  and  to  the  extent  there  is  any
the  named  executive  officer
significant  vote  against 
compensation  as  disclosed  in  this  proxy  statement,  we  will
consider  our  stockholders’  concerns  and  the  Compensation
and  H.R.  Committee  will  evaluate  whether  any  actions  are
necessary to address those concerns.

20

PROPOSAL FOUR
APPROVAL ON A NON-BINDING, ADVISORY BASIS,
OF THE FREQUENCY WITH WHICH
STOCKHOLDERS WILL VOTE ON OUR NAMED
EXECUTIVE OFFICER COMPENSATION

At  our  Annual  Meeting  in  March  2011,  our  stockholders
indicated that they would like to have an annual advisory vote
the
on  executive  compensation.  We  are  required  by 
Dodd-Frank  Act  to  seek  a  separate  advisory  vote  at  least
every six years regarding the frequency of the ‘‘say-on-pay’’

vote. Stockholders may indicate whether they would prefer an
advisory vote on named executive officer compensation once
every one, two or three years. Stockholders may abstain by
submitting a proxy card without instruction on Proposal Four
or by checking the box labeled ‘‘Abstain.’’

Recommendation
The Board of Directors does not make a recommendation
on the frequency with which stockholders will vote on our
named executive officer compensation.

Vote Required
The affirmative vote of the holders of a majority of the votes
cast  is  required  to  approve  the  frequency  with  which
stockholders will cast advisory votes at our annual meetings to
approve named executive officer compensation. If none of the
alternatives  of  every  one  year,  two  years  or  three  years
receives a majority vote, we will consider the highest number
of  votes  cast  by  stockholders  to  be  the  frequency  that  has
been selected by stockholders. However, because this vote is
advisory and not binding on the Board of Directors in any way,
the Board of Directors may decide that it is in the best interests
of  our  stockholders  to  hold  an  advisory  vote  on  executive
compensation  more  or  less  frequently  than  the  option
approved by our stockholders.

Compliance

Section  16(a)  of  the  Securities  Exchange  Act  of  1934  (the
‘‘Exchange  Act’’)  requires  our  officers  and  directors,  and
persons who own more than ten percent of a registered class
of  our  equity  securities  to  file  reports  of  ownership  and
changes in ownership with the SEC. Such officers, directors
and ten-percent stockholders are also required by SEC rules
to furnish us with copies of all forms that they file pursuant to

Section  16(a).  Based  solely  on  our  review  of  the  copies  of
such  forms  received  by  us,  and  on  written  representations
from  certain  reporting  persons  that  no  other  reports  were
required for such persons, we believe that, during fiscal 2016,
our officers, directors and, to our knowledge, greater than ten
percent 
complied  with  all  applicable
stockholders 
Section 16(a) filing requirements.

COMPENSATION DISCUSSION AND ANALYSIS

Introduction
In this section, we describe the material components of our executive compensation program for our ‘‘Named Executive Officers’’
or ‘‘NEOs’’: Ms. Simonet and Messrs. Ambroseo, Palatnik, Sobey, Sechrist and DiMarco. Mr. Palatnik was hired in February 2016
and Ms. Simonet retired in 2016.

We also provide an overview of our executive compensation philosophy, principal compensation policies and practices by which
the Compensation and H.R. Committee, or the committee, arrives at its decisions regarding NEO compensation.

NEO Compensation Overview
The following chart sets forth our compensation philosophy and design principles:

Compensation Philosophy

Compensation Design Principles

Retain and hire talented
executives

Pay for performance, with both
short and long-term
measurements

Our executives should have market competitive compensation and the committee
orients our target total compensation generally near the 50th percentile of the
committee’s selected peer group, with actual compensation falling above or below
depending upon our financial performance and the performance of our stock price
against the Russell 2000 Index over a three-year vesting period. Compensation
components may be above or below such percentile target and varies by
individual executive.
A significant portion of the annual compensation of our executives is designed to
vary with annual business performance and the long-term relative performance of
our stock price in comparison to the Russell 2000 Index (by way of a single three
year vesting period).

Align compensation with
stockholder interests

Tie compensation to performance Our fiscal 2016 annual cash incentive plan was dependent upon corporate
achievement of two demanding performance targets: revenue and adjusted
of the core business
EBITDA dollars. The committee determined that these were the most effective
metrics for tying management’s compensation directly to our core operating
results for fiscal 2016.
Our stockholders benefit from continued strong operating performance by the
Company and we believe that having a significant portion of compensation tied to
equity with both time and performance-based vesting requirements directly aligns
management to stockholder returns. Performance-based RSUs make up the
largest potential portion of the equity grants for our CEO, and make up a
significant potential portion of the equity grants of our other NEOs. Grants of
performance-based RSUs in fiscal 2016 have the same measurement as in fiscal
2015: a single vesting date three years from grant solely dependent upon the
performance of our common stock price measured against the Russell 2000
Index, with target at meeting the index’s performance.

Compensation Overview
Compensation  Philosophy. We 
total
compensation  to  stockholder  value  with  two  measures:  our
operational  results  and  the  comparative  performance  of  our
stock price. This approach provides strong alignment between
executive  pay  and  performance  and  focuses  executives  on
making decisions that enhance our stockholder value in both
the  short  and 
long-term.  We  design  our  executive
compensation program to achieve the following goals:

• Pay  for  performance,  with  both  short  and  long-term
measurements—A  significant  portion  of 
the  annual
compensation  of  our  executives  is  designed  to  vary  with
annual  business  performance  and  the  long-term  relative
performance of Coherent’s stock price in comparison to the
Russell 2000 Index (by way of a single three year vesting
period).  The  committee  and  management  set  demanding
performance  targets,  so  that  even  though  the  Company’s
financial  performance  was  solid  in  fiscal  2014  and  2015,
payouts were not as robust. In fiscal 2016, the Company’s
financial performance was stronger than expected, resulting
in high payouts under our annual cash incentive plan.

• Tie  compensation 

to  performance  of 

the  core
business—Our fiscal 2016 annual cash incentive plan was
dependent  upon  Coherent’s  achievement  against  two
criteria:  adjusted  EBITDA  dollars  and  revenue.  The
committee  determined  that  these  were  the  most  effective
metrics  for  tying  management’s  compensation  directly  to
Coherent’s core operating results for fiscal 2016.

• Retain  and  hire  talented  executives—Our  executives
should  have  market  competitive  compensation  and  the
committee orients our target total compensation generally
near  the  50th  percentile  of  the  committee’s  selected  peer
group  (as  noted  below),  with  actual  compensation  falling
above  or  below  depending  upon  Coherent’s  financial
performance.

performance-based  RSUs  make  up  the  largest  potential

measurement as in fiscal 2015: a single vesting date three
years from grant solely dependent upon the performance of

stockholder 

to 

Coherent’s  common  stock  price  measured  against  the
Russell  2000  Index,  with  target  at  meeting  the  index’s
performance. For each 1% that Coherent’s common stock
exceeds the performance of the Russell 2000 Index for the
trailing 90 trading days from the vesting measurement date
against the comparable period from the date of grant, the
grant  recipient  will  get  a  2%  increase  in  the  number  of
shares  above  target  (up  to  a  maximum  cap  of  200%  of
target),  and  for  each  1%  below  the  Russell  2000  Index’s
performance, a 4% decrease in the number of shares below
target (down to zero). As a result, compensation decreases
faster for failing to achieve the target than it increases for
exceeding it. If Coherent’s stock underperforms the Russell
2000  performance  by  more  than  25%,  then  there  is  no
payout,  but  in  order  to  hit  the  maximum  possible  payout,
Coherent’s  stock  has  to  outperform  the  index  by  at  least
50%.  Accordingly,  for  our  executives  to  achieve  the
committee’s  targeted  compensation,  Coherent’s  common
stock must at least meet the Russell 2000 Index. The chart
below illustrates this structure:

Elements  of  Executive  Compensation. During  fiscal  2016,
the compensation of our NEOs primarily consisted of (A) base
salary, (B) participation in our annual variable compensation
plan (referred to herein as our ‘‘annual cash incentive plan’’ or
‘‘VCP’’),  and  (C)  long-term  equity  incentive  awards  divided
between  time-based  RSUs  and  performance-based  RSUs.
For fiscal 2016, on average, approximately 77% of our NEO’s
target  compensation  and  approximately  87%  of  our  CEO’s

• Our performance-based RSU program is measured by the
Company’s  stock  price  achievement  against  the  Russell
2000  over  a  three  year  period,  which  the  committee
believes is a direct connection to long-term total stockholder
return;

• The committee is composed entirely of directors who satisfy
the  standards  of  independence  in  Coherent’s  Corporate
Governance Guidelines and Nasdaq listing standards;

• The committee makes decisions regarding Mr. Ambroseo’s

compensation without him present;

• Executive incentive compensation programs include limits
on  maximum  payouts  to  contain  the  risk  of  excessive
payouts;

Our  CEO’s  performance-based  cash  compensation  was

Compensation  Governance.
‘‘Pay  for  performance’’  has
been  and  remains  at  the  core  of  Coherent’s  executive
compensation coupled with appropriately managing risk and
aligning  our  compensation  programs  with 
long-term
stockholder interests. We accomplish this primarily by having
a majority of our NEOs’ potential compensation being ‘‘at risk’’
through  a  combination  of  (i)  a  fiscal  year  variable  cash
incentive program tied to achievement of financial metrics and
(ii) equity grant vesting tied to achievement of a performance
metric.  The  committee  monitors  and  considers  evolving
governance  approaches  and  standards 
in  executive
compensation, as well as communications it receives directly
from stockholders.

As more fully discussed below, recent examples of how this
philosophy  is  applied  and  changes  made  pursuant  to
compensation  practices  as  well  as  governance  practices  in
effect during fiscal 2016, include:

• We have a recoupment or ‘‘claw-back’’ policy for our Chief
Executive Officer and Chief Financial Officer, as described
below;

• We  have  minimum  share  ownership  requirements  for  our
Chief  Executive  Officer  and  members  of  the  Board  of
Directors;

• Our  change-of-control  plan  provides  for  payment  only  in
‘‘double-trigger’’ circumstances, that is a change of control
coupled with a termination of employment;

• None of our NEOs are entitled to any ‘‘gross-up’’ to offset
the  impact  of  IRS  Code  Sections  280G  or  4999  in
connection with a change of control; and

• None of our NEOs have other than ‘‘at will’’ employment.

Our  stockholders  have  historically  strongly  supported  our
executive compensation philosophy and design as seen in the
significant  majorities  approving  our  ‘‘say  on  pay’’  proposal

Compensation Discussion and Analysis

Role of Management
The committee regularly meets with Mr. Ambroseo, our Chief
Executive Officer, to obtain recommendations with respect to
the compensation programs, practices and packages for our
NEOs other than Mr. Ambroseo. Additionally, Mr. Palatnik, our
Executive  Vice  President  and  Chief  Financial  Officer,
Mr. DiMarco, our Executive Vice President. General Counsel
and  Corporate  Secretary,  and  members  of  our  human
resources department are regularly invited to meetings of the
committee or otherwise asked to assist the committee.

providing  legal  advice,  developing  compensation  proposals
for  consideration,  and  providing  insights  regarding  our
employees  (executive  and  otherwise)  and  the  business
context for the committee’s decisions. NEOs attend portions of
committee meetings when invited by the committee, but leave
the  meetings  when  matters  potentially  affecting  them  are
discussed.

Role of the Committee’s Compensation Consultant
The  committee  utilizes  the  services  of  an  independent
fiscal  2016,  engaged
compensation  consultant  and 
Compensia  as  its  independent  compensation  consultant.
Compensia assisted the committee by:

in 

• Reviewing  and  analyzing  our  executive  compensation
program,  including  providing  NEO  tally  sheets  to  the
Committee at each of its regular meetings;

• Providing  market  data  and  ranges 

for 

fiscal  2016

compensation; and

• Providing  further  insight  on  compensation  governance

trends.

Additionally,  in  fiscal  2016,  Compensia  was  retained  by  the
Governance  and  Nominating  Committee  to  review,  analyze
and  make  recommendations  regarding  compensation  for
service on the Board of Directors and its committees.

The  independent  compensation  consultant  serves  at  the
discretion of the committee and is not permitted to do other
work  for  Coherent  unless  expressly  authorized  by  the
committee.  Since  retention,  Compensia  has  not  performed
any work for Coherent other than its work with the committee,
the  Board  of  Directors  or  other  committees  of  the  Board  of
Directors.  The  committee  is  focused  on  maintaining  the
independence  of 
its  compensation  consultant  and,
accordingly, does not anticipate having its consultant perform
any other work for the Company in addition to its direct work
for  the  committee,  the  Board,  or  another  committee  of  the
Board.  The  committee  has  assessed  the  independence  of
Compensia and concluded that no conflict of interest exists.

in  and  maintains  a
The  Company  also  participates 
subscription to the Radford Global Technology Survey. This
survey provides benchmark data and compensation practices
reports  of  a  broad  cross-section  of  technology  companies
similar  in  size  to  Coherent  to  assist  us  with  regards  to
employee compensation generally.

Pay Positioning Strategy and
Benchmarking of Compensation
Philosophically  the  committee  initially  orients  target  total
compensation for our NEOs generally near the 50th percentile
of our peers (as measured by our designated peer group and,
when  applicable,  data  from  the  Radford  Global  Technology
Survey),  resulting  in  targeted  total  compensation  that  is
competitive  for  performance  that  meets  the  objectives
established by the committee. An NEO’s actual salary, cash
incentive compensation opportunity and equity compensation
grant value may fall below or above the target position based
on  the  individual’s  experience,  seniority,  skills,  knowledge,
performance  and  contributions  as  well  as  the  historical  pay
structure  for  each  executive.  These  factors  are  weighed
individually  by  the  committee  in  its  judgment,  and  no  single
factor takes precedence over others nor is any formula used in
making these decisions. In light of the fact that the committee

32

has  designed  the  significant  majority  of  the  Chief  Executive
Officer’s  compensation  to  be  at  risk,  including  2⁄3  of  his
long-term equity compensation, for fiscal 2016 the committee
asked  Compensia  to  provide  information  at  the  50th  and
75th  percentile  for  our  Chief  Executive  Officer.  Given  the
significant  ties  to  performance  and  with  such  a  large
percentage  of  his  potential  compensation  at  risk,  the
committee  oriented  his  compensation  target  closer  to  the
75th percentile.

The Chief Executive Officer’s review of the performance of the
other  NEOs  is  considered  by  the  committee  in  making
individual pay decisions. With respect to the Chief Executive
Officer, 
the
performance  of  Coherent  as  a  whole  and  the  views  of  the

committee  additionally 

considered 

the 

Board  of  Directors  regarding  the  Chief  Executive  Officer’s
performance. Actual realized pay is higher or lower than the
targeted amounts for each individual based primarily on the
Company’s  performance.  For  example,  the  performance
RSUs granted in 2013 only vested in 2016 as to 60% of target,
which resulted in value received that is significantly lower than
the ‘‘accounting value’’ for equity compensation for each NEO
reflected in the summary compensation table for that year.

In analyzing our executive compensation program relative to

this 
information  provided  by

its 
consultant,  which  includes  an  analysis  of  data  from  peer
companies’  proxy  filings  with  respect  to  similarly  situated
individuals  at  the  peer  companies  (when  available)  and  the
Radford  Global  Technology  Survey  (as  a  supplement  when
peer  group  company  data  is  unavailable).  It  is  important  to
note that these are the peers selected by the committee. The
committee uses criteria as described below in determining the
appropriate  group.  There  are  proxy  advisory  services  which
use  their  own  criteria  to  select  peers  for  the  Company  and,
accordingly, stockholders should be aware that these advisory
services do not, in fact, follow the same methodology of the
committee  and  there  may  be  wide  variances  between  the
different peer groups used by these services. Any comparison
of  company  performance  or  market  data  for  executive
compensation  using  a  completely  different  peer  group  will,
therefore,  naturally  result 
in  a  different  analysis.  We
encourage our stockholders to consider the peer group used
in any comparisons and direct any questions to the committee
regarding  such  comparisons  or  any  other  matters  when
considering how to vote on Proposal Three.

For pay decisions made for fiscal 2016, after consulting with
our  independent  compensation  consultant,  the  committee
determined  that  the  following  companies  comprise  the  peer
group for fiscal 2016:

Several factors are considered in selecting the peer group, the
most important of which are:

Primary Criteria
• Industry (primarily companies in the Electronic Equipment
and Semiconductor sub-industry classifications defined by
the Global Industry Classification Standard (GICS) system);
and

• Revenue level (primarily companies with annual revenues

between 0.5x-2.0x that of Coherent).

Secondary Criteria
• Market capitalization between 0.25x and 3.0x of Coherent;

• Market  capitalization  as  a  multiple  of  revenues  of  greater

than 1.5x; and

• A disclosed peer of a peer company.

The  committee  reviews  the  composition  of  the  peer  group
annually to ensure it is the most relevant set of companies to
use for comparison purposes.

Components of Our Executive
Compensation Program
The  principal  components  of  our  executive  officer
compensation  and  employment  arrangements  during  fiscal

Base Salary
Base salary is the foundation to providing an appropriate total
direct  compensation  package.  We  use  base  salary  to  fairly
and competitively compensate our executives for the jobs we
ask them to perform. This is the most stable component of our
executive compensation program, as this amount is not at risk.
The committee reviewed market data information provided by
Compensia  with  respect  to  similarly  situated  individuals  to
assist  it  in  determining  the  base  salary  for  each  NEO,
depending  upon 
the  particular  executive’s  experience,
seniority,  skills,  knowledge,  performance  and  contribution.
There were no increases to the base salaries of our NEOs for
fiscal 2016.

Variable Cash Incentive Compensation
A substantial portion of each individual’s potential short-term
compensation  is  in  the  form  of  variable  incentive  cash
compensation  tied  to  committee-established  goals.  In  fiscal

34

2016, Coherent maintained one incentive cash program under
which executive officers were eligible to receive annual cash
incentives,  the  2016  Variable  Compensation  Plan  (‘‘2016
VCP’’).

2016 VCP
The  2016  VCP  was  designed  as  an  ‘‘at  risk’’  bonus
compensation  program  to  promote  a  focus  on  Coherent’s
growth  and  profitability.  It  provided  incentive  compensation
opportunity  in  line  with  targeted  market  rates  to  our  NEOs.
Under  the  2016  VCP,  participants  were  eligible  to  receive
bi-annual bonuses (with measurement periods for the first half
and  the  second  half  of  the  2016  fiscal  year).  In  setting  the
performance  goals  at  the  beginning  of  the  fiscal  year,  the
committee assessed the anticipated difficulty and importance
to  the  success  of  Coherent  of  achieving  the  performance
goals.

The  actual  awards  (if  any)  payable  for  each  semi-annual
period  varied  depending  on  the  extent  to  which  actual
performance met, exceeded or fell short of the goals approved
by the committee. The 2016 VCP goals were tied to Coherent
achieving  varying  levels  of  revenue  and  adjusted  EBITDA
dollars (‘‘adjusted EBITDA $’’), with revenue weighted at 25%
and adjusted EBITDA $ weighted at 75%. Each performance
metric  is  measured  and  paid  out  independently,  but  the
revenue payout is capped at 100% achievement until adjusted
EBITDA $ reaches a minimum dollar target. Adjusted EBITDA
is  defined  as  earnings  before  interest,  taxes,  depreciation,
amortization  and  certain  other  non-operating  income  and
expense items and other items, such as the impact of stock
option  expensing  under 
the  Accounting  Standards
Codification 718, ‘‘Compensation—Stock Compensation’’ and
certain  acquisition  related  expenses.  The  Committee  also
reviews  the  financial  impact  of  mergers  and  acquisitions  to
determine if any adjustments in VCP are required.

Each  measurement  period  had  the  same  range  of  between
zero  and  200%,  with  target  at  100%  of  the  executive’s
participation rate.

Fiscal 2016 Variable Compensation
Plan Scale for NEOs
Revenue  achievement  for  the  first  half  of  fiscal  2016  was
$390.2 million, with a corresponding cash incentive payout of
approximately  16.7%  of 
target.  Adjusted  EBITDA  $
achievement for the first half of fiscal 2016 was $88.7 million,
with a corresponding cash incentive payout of approximately
130.2%  of  target.  The  weighted,  combined  cash  incentive
payout for the first half was approximately 101.8% of target.

Equity Awards
We  believe  that  equity  awards  provide  a  strong  alignment
between the interests of our executives and our stockholders.
We  seek  to  provide  equity  award  opportunities  that  are
consistent  with  our  compensation  philosophy,  with  the
potential  for  increase  for  exceptional  financial  performance,
consistent with the reasonable management of overall equity
compensation  expense  and  stockholder  dilution.  Finally,  we
believe that long-term equity awards are an essential tool in
promoting executive retention. For fiscal 2016, our long-term
incentive program included the grant of time-based RSUs and

35

Compensation Discussion and Analysis

performance-based  RSUs.  These  components  provide  a
reward for past corporate and individual performance and as
an incentive for future performance. Our performance-based
RSU grants are tied to the Company’s performance and, as a
result, may fluctuate from no vesting to vesting which is above
target.  When  making

its  compensation  decisions, 

Fiscal 2016 Equity Grants
For fiscal 2016, the committee based the equity program on a
combination  of  time-based  and  performance-based  RSUs
over  a  three  year  period.  In  particular,  the  committee
determined  to  measure  achievement  for  the  performance
grants by the relative performance of Coherent’s stock price in
comparison  to  the  Russell  2000  Index.  The  committee
believed that using the Russell 2000 Index (in which Coherent
is  a  member)  as  a  proxy  of  total  stockholder  return  directly
aligns executive compensation with stockholder interest. The
committee determined that both the performance-based and
time-based RSU grants provide a further retention tool in that

the  time-based  grants  vest  over  three  years  with  pro  rata
annual  vesting  and,  for  the  performance-based  grants,  a
single measurement period three years from the date of grant
with  three-year  cliff  vesting  shortly  thereafter  if  such  grants
vest  at  all  since  such  grants  vest  purely  based  on
performance.

Performance-based  RSU  grants  in  fiscal  2016  vest  solely
dependent  upon  the  performance  of  Coherent’s  common
stock  price  measured  against  the  Russell  2000  Index.  For
each  1%  that  Coherent’s  common  stock  exceeds  the
performance  of  the  Russell  2000  Index  for  the  trailing  90
trading days from the vesting measurement date against the
comparable period from the date of grant, the grant recipient
will get a 2% increase in the number of shares above target
(up to a maximum cap of 200% of target), and for each 1%
below the Russell 2000 Index’s performance, a 4% decrease
in  the  number  of  shares  (down  to  zero).  As  a  result,
compensation decreases faster for failing to achieve the target
than  it  increases  for  exceeding  it.  The  performance-based
RSUs  make  up  the  largest  potential  portion  of  the  equity
grants for our Chief Executive Officer.

The following table summarizes some of the key features of our fiscal 2016 equity grants:

For our Chief Executive Officer, greater than half of his total
equity awards are performance-based. Accordingly, for our
Chief  Executive  Officer,  at  target,  approximately  66%  of  his
equity  awards  are  performance-based  and  at  maximum
achievement  that  percentage  increases  to  approximately
80%.

In  the  event  of  a  change  of  control  of  the  Company,  the
performance-based grants will be measured, with respect to

performance periods not yet completed, by the relative stock
performance of Coherent in comparison to the Russell 2000
Index  through  the  date  of  the  change  of  control  and  such
performance-based shares would, subject to the terms of the

Equity Award Practices
Equity  grants  to  our  employees  are  driven  by  our  annual
review  process.  Grant  guidelines  are  based  on  competitive
market  practices.  Typically,  an  eligible  employee  is  granted
first  committee  meeting  after  beginning
equity  at 
employment and may be eligible for periodic grants thereafter.
Eligibility  for  and  the  size  of  grants  are  influenced  by  the
then-current  guidelines  for  non-executive  officer  grants  and
the individual’s performance or particular requirements at the
time of hire. No option grants have been made to an employee
since 2010.

In fiscal 2016 the committee granted an aggregate of 379,295

shares  subject

representing
approximately  1.56%  of  Coherent’s  outstanding  common
stock  as  of  September  30,  2016  (excluding  automatic  and
initial grants to directors). With the assistance of Compensia,
the  committee  has  reviewed  this  burn  rate  relative  to  peer
practices  and  guidance 
Institutional  Shareholder
from 
Services (ISS) and found that the total dilution was consistent
with  the  median  of  peer  practices  and  complied  with  ISS
guidelines.

During fiscal 2016 equity grants were only made at meetings
of the committee.

Chief Executive Officer Minimum Stock Ownership
Guidelines
During fiscal 2012, the committee adopted mandatory stock
ownership  guidelines  for  our  Chief  Executive  Officer.  Our
guidelines require that the Chief Executive Officer hold shares
with  a  value  of  at  least  three  times  base  salary,  without
counting vested or unvested option grants or unvested grants
of  RSUs.  Compliance  is  measured  as  of  the  date  of  each
year’s annual meeting based on the stock price of the shares
as of the date of their acquisition. In the event that our Chief
Executive Officer does not satisfy the minimum requirements,
then 25% of the net after-tax shares (e.g. exercised options/
shares received on the vesting of RSUs) are required to be
held until the guidelines are met. As of December 31, 2016,
Mr. Ambroseo held outstanding stock worth approximately 31
times his base salary and, accordingly, significantly exceeded
the minimum stock ownership guidelines.

The  following  charts  show  the  aggregate  composition  of
equity grants for fiscal 2016 to our Chief Executive Officer, at
target and at maximum achievement under the terms of the
performance-based grants:

Other Benefits
Retirement Plans
Executive  officers  are  eligible  to  participate  in  our  401(k)
Retirement  Plan  on  the  same  terms  as  all  other  U.S.
employees, including a 4% Company matching contribution.
Our 401(k) Retirement Plan is intended to be a tax-qualified
plan and therefore is subject to certain Internal Revenue Code
limitations  on  the  dollar  amounts  of  deferrals  and  Company
contributions  that  can  be  made  to  plan  accounts.  These
limitations apply to our more highly-compensated employees
(including the NEOs).

We  maintain  a  Deferred  Compensation  Plan  for  certain
employees  and  members  of  the  Board.  The  Deferred
Compensation  Plan  permits  eligible  participants  to  defer
receipt of compensation pursuant to the terms of the plan. The
to
Deferred  Compensation  Plan  permits  participants 
contribute, on a pre-tax basis, up to 75% of their base salary
earnings, up to 100% of their bonus pay and commissions and
up  to  100%  of  directors’  annual  retainer  earned  in  the
upcoming  plan  year.  We  provide  no  matching  or  other
additional contributions to such Deferred Compensation Plan.
Plan participants may invest deferrals in a variety of different
deemed  investment  options.  To  preserve  the  tax-deferred
status of deferred compensation plans, the IRS requires that
the  available 
‘‘deemed
investments.’’ Participants do not have an ownership interest
in the funds they select; the funds are only used to measure
the  gains  or  losses  that  are  attributed  to  the  participant’s
deferral account over time.

investment  alternatives  be 

The committee considers the Deferred Compensation Plan to
be  a  reasonable  and  appropriate  program  because  it
promotes  executive  officer  retention  by  offering  a  deferred
compensation plan that is comparable to and competitive with
what is offered by our peer group of companies.

Employee Stock Purchase Plan
Our stockholders have approved an employee stock purchase
plan whereby employees can purchase shares for a discount,

subject to various participation limitations. As employees, our
NEOs are eligible to participate in this plan.

Severance and Change of Control Arrangements
Our  Change  of  Control  Severance  Plan  (the  ‘‘Change  of
Control  Plan’’)  provides  certain  benefits  in  the  event  of  a
change of control of Coherent for certain executives, including
each of our NEOs. Benefits are provided if there is a change in
ownership  of  Coherent,  a  change  in  effective  control  of
Coherent, or a change in ownership of a substantial portion of
Coherent’s  assets  (in  each  case  as  construed  under
Section  409A  of  the  Internal  Revenue  Code  and  the
regulations thereunder)(a ‘‘change of control’’) and within two
years  thereafter  (or  within  two  months  prior  thereto)  the
participant’s  employment  is  terminated  without  cause  or
voluntarily  terminates  following  a  constructive  termination
event.  The  committee  believes  the  Change  of  Control  Plan
serves as an important retention tool in the event of a pending
change of control transaction.

The committee completed its review of the provisions of the
Change of Control Plan during fiscal 2015 and determined to
review the plan again in four years. Compensia assisted the
Committee in its review and analysis of the Change of Control
Plan.  The  committee  believes  that  reviewing  the  Change  of
Control Plan every four years allows for the right balance in
providing  certainty  for  the  participants  while  providing  the
committee with the opportunity to revise the plan consistent
with  corporate  governance  best  practices,  evolving  peer
group practices and regulatory changes.

The committee does not consider the potential payments and
benefits  under 
these  arrangements  when  making
compensation decisions for our NEOs. These arrangements
serve specific purposes unrelated to the determination of the
NEOs’ total direct compensation for a specific year.

Tax and Accounting Considerations
Accounting for Stock-Based Compensation—We account for
stock-based  compensation 
the
requirements  of  ASC  718.  We  also  take  into  consideration
ASC 718 and other generally accepted accounting principles
in determining changes to policies and practices for our stock-
based compensation programs.

in  accordance  with 

Section 162(m) of the Internal Revenue Code—This section
limits  Coherent’s  income  tax  deduction  of  compensation  for
our  Chief  Executive  Officer  and  our  four  other  most  highly
compensated  NEOs  (other  than  the  Chief  Financial  Officer)
unless  the  compensation  is  less  than  $1  million  during  any
fiscal year or is ‘‘performance-based’’ under Section 162(m).
Our 2001 Stock Plan and 2011 Plan are designed to permit

38

Compensation Discussion and Analysis

option  grants  and  certain  performance-based  full  value
awards  to  be  fully  tax-deductible.  Cash  compensation
(including  both  base  salary  and  payments  under  our  2016
VCP)  and  time-based  full-value  awards  are  not  qualified  as
‘‘performance-based’’  compensation  under  Section  162(m).
We may from time to time pay compensation to our executive
officers  (including  under  our  VCP)  that  may  not  be  tax
deductible  when, 
that  such
compensation is appropriate and in the best interests of the
stockholders  after  taking  various  factors  into  consideration,
including  business  conditions  and  the  performance  of  the
executive  officer.  In  addition,  due  to  the  ambiguities  and

for  example,  we  believe 

uncertainties  as  to  the  application  and  interpretation  of
Section 162(m) as well as operational issues, no assurances
can be given that compensation, even if intended to satisfy the
requirements for deductibility under Section 162(m), would in
fact do so.

Section  409A  of  the  Internal  Revenue  Code—Section  409A
imposes  additional  significant  taxes  in  the  event  that  an
executive  officer,  director  or  service  provider  received
‘‘deferred  compensation’’ 
the
requirements of Section 409A. We consider Section 409A in
the design and operation of any plans.

that  does  not  satisfy 

Other Compensation Policies
To further align our executive compensation program with the
interests  of  our  stockholders,  at  the  end  of  fiscal  2009,  a
committee of the Board approved a recoupment policy. The
recoupment policy provides that, in the event that there is an
accounting  restatement  and  there  is  a  finding  by  the  Board
that such restatement was due to the gross recklessness or
intentional misconduct of the Chief Executive Officer or Chief
Financial Officer and it caused material noncompliance with
any financial reporting requirement, then Coherent shall seek
disgorgement of any portion of the bonus or other incentive or

equity  based  compensation  related  to  such  accounting
restatement received by such individual during the 12-month
period following the originally filed financial document. Under
our  Insider  Trading  Policy,  no  employees  or  directors  are
allowed  to  hedge  or  pledge  Coherent  securities.  The
Committee continues to monitor the SEC rule-making related
to Section 954 of the Dodd-Frank Act. Following the final rules
being adopted by the SEC, the Committee intends to review
and update its clawback policy.

Compensation Committee Interlocks and Insider Participation
During fiscal 2016, the Compensation and H.R. Committee of the Board consisted of Messrs. Vij (Chair), Flatley and Krause.
None of the members of the committee has been or is an officer or employee of Coherent. None of our executive officers serve on
the  board  of  directors  or  compensation  committee  of  a  company  that  has  an  executive  officer  that  serves  on  our  Board  or
Compensation and H.R. Committee. No member of our Board is an executive officer of a company in which one of our executive
officers serves as a member of the board of directors or compensation committee of that company.

Committee Independence
Each of the members of the committee qualifies as (i) an ‘‘independent director’’ under the requirements of The Nasdaq Stock
Market, (ii) a ‘‘non-employee director’’ under Rule 16b-3 of the Securities Exchange Act of 1934 (the ‘‘1934 Act’’), (iii) an ‘‘outside
director’’ under Section 162(m) of the Code and (iv) an ‘‘independent outside director’’ as that term is defined by ISS.

Compensation and H.R. Committee Report
The Compensation and H.R. Committee of the Board has reviewed and discussed the Compensation Discussion and Analysis
required by Item 402(b) of Regulation S-K with management and, based on such review and discussions, the Compensation and
H.R. Committee recommended to the Board that the Compensation Discussion and Analysis be included in this Proxy Statement.

Failure to meet a minimum level of performance would have resulted in no bonus paid out under the 2016 Variable Compensation Plan.

(2) Reflects the amount earned under the 2016 Variable Compensation Plan during the 2016 fiscal year.

(3) Reflects the dollar amount recognized for financial statement reporting purposes (disregarding an estimate of forfeitures related to service-based vesting

conditions) for fiscal 2016 in accordance with ASC 718, and includes grants made in fiscal 2016. The assumptions used in the valuation of these awards are set

forth in Note 12 ‘‘Employee Stock Option and Benefits Plans’’ of the Financial Statements in the Annual Report on Form 10-K. For informational purposes, if the

maximum level of performance for the PRSU awards was achieved, the value, calculated by multiplying the closing price of the Company’s common stock on

the date of grant by the number of shares issuable upon achievement of the maximum level of performance under the PRSU is $4,182,610, $1,322,160,

$525,360, $447,814 and $457,950, for Mr. Ambroseo, Mr. Palatnik, Mr. Sobey, Mr. Sechrist and Mr. DiMarco, respectively. These amounts do not correspond

to the actual value, if any, that will be recognized by the NEOs. See ‘‘Compensation Discussion and Analysis-Equity Awards’’ for a description of the PRSUs.

Summary Compensation and Equity Tables

Potential Payments upon Termination or Change of Control

The following table shows the potential payments and benefits
that  we  (or  our  successor)  would  be  obligated  to  make  or
provide  upon  termination  of  employment  of  each  our  NEOs
pursuant  to  the  terms  of  the  Change  of  Control  Severance
Plan.  Other  than  this  plan,  there  are  no  other  executive
employment  agreements  or  other  contractual  obligations
triggered upon a change of control. For purposes of this table,
it is assumed that each NEO’s employment terminated at the
close  of  business  on  September  30,  2016  (the  last  trading
date  before  the  end  of  our  fiscal  year  on  October  1,  2016).
These payments are conditioned upon the execution of a form
release  of  claims  by  the  NEO  in  favor  of  us.  The  amounts
reported  below  do  not  include  the  nonqualified  deferred

compensation distributions that would be made to the NEOs
following a termination of employment (for those amounts and
descriptions, see the prior table). There can be no assurance
that  a  triggering  event  would  produce  the  same  or  similar
results as those estimated below if such event occurs on any
other  date  or  at  any  other  price,  of  if  any  other  assumption
used  to  estimate  potential  payments  and  benefits  is  not
correct. Due to the number of factors that affect the nature and
amount  of  any  potential  payments  or  benefits,  any  actual
payments and benefits may be different. These are aggregate
payments  and  do  not  reflect  such  individual’s  net  after  tax
benefit.  No  officer  is  entitled  to  any  ‘‘gross  up’’  to  offset  the
impact of IRS Code Section 280G.

(1) Reflects salary as in effect as of December 31, 2016. Bonus severance is based on a percentage of salary as in effect as of

December 31, 2016.

(2) Equity Compensation Acceleration is the in-the-money value of unvested stock options, time-based restricted stock units
and performance-based restricted stock units, in each case as of September 30, 2016 (the last trading date before the end
of  our  fiscal  year)  at  the  closing  stock  price  on  that  date  ($110.54).  The  value  of  accelerated  stock  options  are  thus

46

Summary Compensation and Equity Tables

calculated by multiplying the number of unvested shares subject to acceleration by the difference between the exercise
price  and  the  closing  stock  price  on  September  30,  2016;  the  value  of  accelerated  restricted  stock  is  calculated  by
multiplying the number of unvested shares subject to acceleration by the closing stock price on September 30, 2016. This
assumes immediate release and vesting of the performance-based restricted stock units at the maximum, or 200% of
target, achievement. The amounts reflected for Equity Compensation Acceleration do not reflect any applicable taxes, just
gross proceeds. Since the table assumes a triggering event on September 30, 2016, only those stock options and restricted
stock/RSU grants outstanding as of that date are included in the table.

(3) Aggregate Healthcare Related Monthly Payment is a monthly payment of $2,750 in lieu of receiving company subsidized
COBRA benefits, life insurance premiums and/or other welfare benefits, 36 months for the Chief Executive Officer and
24 months for the other NEOs.

To assist with the transition in connection with her retirement
as the Company’s Chief Financial Officer, Ms. Simonet agreed
to remain as a special advisor to the Chief Executive Officer as
a  non-executive  employee  from  February  22,  2016  through
April 4, 2016, at which time she transitioned to a consultant to
the  Company  for  the  period  from  April  5,  2016  through
December 30, 2016. The Company entered into a transition
services  agreement  with  Ms.  Simonet  continuing  her

compensation  through  April  4,  2016  and  providing  for  an
aggregate of $100,000 (paid in equal monthly increments) for
no more than 20 hours of consulting services per month from
April 5, 2016 through December 30, 2016. During the term of
the transition services agreement, Ms. Simonet continued to
vest in her existing equity grants pursuant to the terms of the
2011  Plan.  The  transition  services  agreement  included
confidentiality obligations.

Review, Approval or Ratification of Related Person Transactions
In accordance with the charter for the Audit Committee of the Board, the members of the Audit Committee, all of whom are
independent directors, review and approve in advance any proposed related person transactions. Additionally, from time to time
the  Board  may  directly  consider  these  transactions.  For  purposes  of  these  procedures,  the  individuals  and  entities  that  are
considered ‘‘related persons’’ include:

• Any of our directors, nominees for director and executive officers;

• Any person known to be the beneficial owner of five percent or more of our common stock (a ‘‘5% Stockholder’’); and

• Any immediate family member, as defined in Item 404(a) of Regulation S-K, of a director, nominee for director, executive officer
and 5% Stockholder. We will report all such material related person transactions under applicable accounting rules, federal
securities laws and SEC rules and regulations.

Related Person Transactions
We  have  entered  into  indemnification  agreements  with  each  of  our  executive  officers  and  directors.  Such  indemnification
agreements require us to indemnify these individuals to the fullest extent permitted by law. We also intend to execute these
agreements with our future directors and officers.

REPORT OF THE AUDIT COMMITTEE OF THE
BOARD OF DIRECTORS

The  Audit  Committee  is  responsible  for  overseeing  our
accounting and financial reporting processes and audits of our
financial  statements,  including  reviewing  and  approving  the
fees  for  the  performance  of  the  audit  by  our  independent
auditors. As set forth in its charter, the Audit Committee acts
only  in  an  oversight  capacity  and  relies  on  the  work  and
assurances  of  both  management,  which  has  primary
responsibilities  for  our  financial  statements  and  reports,  as
well as the independent registered public accounting firm that
is responsible for expressing an opinion on the conformity of
our  audited  financial  statements  to  generally  accepted
accounting principles.

The Audit Committee met twelve (12) times either in person or
by  telephone  during  fiscal  2016.  In  the  course  of  these
meetings,  the  Audit  Committee  met  with  management,  the
internal  auditors  and  our  independent  registered  public
accounting firm and reviewed the results of the internal and
external  audit  examinations,  evaluations  of  our  internal
controls and the overall quality of our financial reporting.

the 

internal  auditors  and 

The Audit Committee believes that a candid, substantive and
focused  dialogue  with 
the
independent registered public accounting firm is fundamental
to the Audit Committee’s oversight responsibilities. To support
this belief, the Audit Committee periodically meets separately
with  the  internal  auditors  and  the  independent  auditors,
without management present. In the course of its discussions
in  these  meetings,  the  Audit  Committee  asked  a  number  of
questions  intended  to  bring  to  light  any  areas  of  potential
concern related to our financial reporting and internal controls.
These questions include:

• Are there any significant accounting judgments, estimates
or  adjustments  made  by  management  in  preparing  the
financial statements that would have been made differently
had 
themselves  prepared  and  been
responsible for the financial statements;

the  auditors 

• Based on the auditors’ experience, and their knowledge of
our business, do our financial statements fairly present to
investors,  with  clarity  and  completeness,  our  financial
position  and  performance  for  the  reporting  period  in
accordance with generally accepted accounting principles
and SEC disclosure requirements;

• Based on the auditors’ experience, and their knowledge of
our  business,  have  we  implemented  internal  controls  and

internal  audit  procedures  that  are  appropriate  for  our
business.

The Audit Committee approved the engagement of Deloitte &
Touche LLP as our independent registered public accounting
firm for fiscal 2016, including the fees to be paid for their audit
work, and reviewed with the internal auditors and independent
registered public accounting firm their respective overall audit
scope  and  plans.  In  approving  Deloitte  &  Touche  LLP,  the
Audit  Committee  considered  the  qualifications  of  Deloitte  &
Touche LLP and discussed with Deloitte & Touche LLP their
independence, including a review of the audit and non-audit
services provided by them to us. The Audit Committee also
discussed with Deloitte & Touche LLP the matters required to
be discussed by Auditing Standard No. 16, ‘‘Communications
with  Audit  Committees’’  issued  by  the  Public  Company
Oversight  Board  (PCAOB),  and  it  received  the  written
disclosures and the letter from Deloitte & Touche LLP required
by  the  applicable  requirements  of  the  Public  Company
regarding  Deloitte  &
Accounting  Oversight  Board 
Touche  LLP’s  communications  with  Audit  Committee
concerning  independence  and  has  discussed  Deloitte  &
Touche LLP’s independence with Deloitte & Touche LLP.

the 

reporting, 

Management  has  reviewed  and  discussed  the  audited
financial statements for fiscal 2016 with the Audit Committee,
including a discussion of the quality and acceptability of the
reasonableness  of  significant
financial 
accounting  judgments  and  estimates  and  the  clarity  of
disclosures in the financial statements. In connection with this
review and discussion, the Audit Committee asked a number
of  follow-up  questions  of  management  and  the  independent
registered  public  accounting  firm  to  help  give  the  Audit
Committee comfort in connection with its review.

In reliance on the reviews and discussions referred to above,
the  Audit  Committee  recommended  to  the  Board  that  the
audited financial statements be included in the annual report
on Form 10-K for the fiscal year ended October 1, 2016, for
filing with the SEC.

PART I

ITEM 1. BUSINESS

GENERAL

Business  Overview

Our fiscal year ends on the Saturday  closest to September 30. Fiscal years 2016,  2015 and 2014
ended on October 1, October 3, and  September 27, respectively, and are referred to in this annual
report as fiscal 2016, fiscal 2015 and fiscal 2014  for convenience. Fiscal  years 2016 and 2014 included
52 weeks and fiscal year 2015 included  53 weeks.

We  are one of the  world’s leading providers  of lasers and laser-based technology in a  broad range
of scientific, commercial and industrial applications. We  design, manufacture, service and market lasers
and related accessories for a diverse  group of customers. Since  inception in 1966,  we have  grown
through internal expansion and through  strategic acquisitions of complementary businesses,
technologies, intellectual property, manufacturing processes  and product  offerings.

We  are organized into two operating  segments:  Specialty Lasers and Systems (‘‘SLS’’) and

Commercial Lasers and Components (‘‘CLC’’). This  segmentation reflects the go-to-market strategies
for various products and markets. While  both  segments deliver cost-effective photonics solutions, SLS
develops and manufactures configurable,  advanced  performance  products largely serving the
microelectronics, scientific research and government programs and  original equipment manufacturer
(‘‘OEM’’) components and instrumentation  markets. The size  and complexity of many  of the SLS
products require service to be performed at the customer site by  factory-trained field service engineers.
CLC focuses on higher volume products  that are offered  in set configurations. The product
architectures are designed for easy exchange  at the  point of use such that substantially  all  product
service and repairs are based upon advanced replacement and depot (i.e., factory)  repair. CLC’s
primary markets include materials processing, OEM components and instrumentation and
microelectronics.

Income from operations is the measure of  profit and loss that our  chief operating decision maker

(‘‘CODM’’) uses to assess performance and make  decisions. Income from operations represents  the
sales less the cost of sales and direct  operating expenses incurred within the operating segments as well
as allocated expenses such as shared sales  and manufacturing costs.  We  do not allocate to our
operating segments certain operating expenses, which  we manage separately  at the  corporate level.
These unallocated costs include stock-based compensation  and corporate  functions (certain  advanced
research and development, management, finance, legal  and human resources)  and are included  in
Corporate and other. Management does not consider unallocated Corporate  and other costs in its
measurement of segment performance.

We  were originally incorporated in California on May 26, 1966  and reincorporated  in Delaware  on

October 1, 1990. Our common stock  is listed on the NASDAQ  Global  Select Market and we  are a
member of the Standard & Poor’s SmallCap 600  Index and  the  Russell 2000  Index.

Additional information about Coherent,  Inc. (referred to herein  as the Company,  we, our, or
Coherent) is available on our web site  at www.coherent.com. We  make available, free of charge on our
web site, access to our annual report on  Form  10-K, our quarterly reports  on Form 10-Q, our current
reports on Form 8-K and amendments  to  those reports filed or furnished pursuant  to  Section 13(a) or
15(d) of the Securities Exchange Act of 1934, as  amended (the ‘‘Exchange  Act’’), as soon as  reasonably
practicable after we file or furnish them electronically with the  Securities  and Exchange
Commission (‘‘SEC’’). Information contained  on our web site is not part of this annual report  or our
other filings with the SEC. Any product,  product name, process, or technology described  in these
materials is the property of Coherent.

RECENT EVENTS

On November 7, 2016, we completed  our  previously announced  acquisition of Rofin-Sinar

Technologies Inc. (‘‘Rofin’’) pursuant  to  the Merger Agreement  dated March 16, 2016. Rofin is  one  of
the world’s leading developers and manufacturers  of high-performance industrial laser sources and
laser-based solutions and components.  As  a  condition  of the acquisition, we are required to divest
ourselves  of Rofin’s low power CO2 laser  business  based in Hull, United  Kingdom, and  will report  this
business separately as a discontinued operation  until it  is divested.  The  acquisition  was an all-cash
transaction at a price of $32.50 per share  of Rofin common  stock.  The aggregate consideration paid by
us to the former Rofin stockholders was  approximately $904.5 million, excluding related transaction
fees and expenses. We also paid $15.3  million  due  to  the cancellation of options held by employees of
Rofin. We funded the payment of the aggregate consideration with a  combination of  our available cash
on hand  and the proceeds from the Euro Term  Loan described below.

As a result of the acquisition of Rofin,  and  subsequent  to  fiscal  2016 year-end, we  announced that

in the first quarter of fiscal 2017 we will reorganize our existing two segments into two new reporting
segments for the combined company,  OEM Laser Systems and  Industrial Lasers and Systems.
Accordingly, our segment information will  be restated retroactively in  the first quarter of fiscal 2017.

On November 7, 2016, we entered into a  Credit Agreement (the ‘‘Credit Agreement’’) with
Barclays  Bank PLC, Bank of America,  N.A., and The  Bank of  Tokyo-Mitsubishi UFJ, Ltd. The Credit
Agreement provided for a 670.0 million  Euro senior secured  term loan  facility  and a  $100.0 million
senior secured revolving credit facility.  On November 7, 2016,  the  Euro  Term Loan was  drawn  in full
and its proceeds were used to finance  the acquisition of Rofin and pay related fees and  expenses. Also,
on November 7, 2016, we used 10.0 million  Euro  of  the capacity under the revolving credit  facility for
the issuance of a letter of credit.

INDUSTRY BACKGROUND

The word ‘‘laser’’ is an acronym for ‘‘light  amplification by stimulated emission of radiation.’’ A

laser emits an intense coherent beam  of  light with some  unique and  highly useful properties. Most
importantly, a laser is orders of magnitude brighter  than  any  lamp. As a result of its coherence, the
beam can be focused to a very small and intense spot,  useful for applications requiring very high power
densities including cutting and other materials processing procedures. The laser’s high spatial resolution
is also useful for microscopic imaging  and inspection applications.  Laser light  can be monochromatic—
all of the beam energy is confined to a narrow wavelength band. Some lasers  can be used to create
ultrafast output—a series of pulses with pulse durations as  short as attoseconds  (i.e., 10(cid:3)18 seconds).

There are many types of lasers and one  way of classifying them is by the material or  medium  used
to create the lasing action. This can be in  the form  of a gas, liquid,  semiconductor,  solid state crystal  or
fiber. Lasers can also be classified by their output wavelength:  ultraviolet, visible, infrared or
wavelength tunable. We manufacture all of these laser types. There  are  also many options in terms of
pulsed output versus continuous wave, pulse duration,  output power, beam dimensions,  etc. In fact,
each  application has its specific requirements  in terms of  laser performance. The broad  technical depth
at Coherent enables us to offer a diverse set  of product  lines  characterized by lasers targeted at  growth
opportunities and key applications. In all  cases, we aim  to  be the supplier of choice by offering a
high-value combination of superior technical performance and high reliability.

Photonics has taken its place alongside electronics as a critical enabling technology  for the  twenty-

first century. Photonics based solutions  are  entrenched in a broad array of industries that include
industrial automation, textile processing,  microelectronics,  flat  panel displays  and medical diagnostics,
with adoption continuing in ever more diverse applications. Growth  in these applications stems from
two sources. First, there are many applications where the  laser is displacing conventional technology
because it can do the job faster, better  or more economically.  Second, there are  new applications where

6

the laser is the enabling tool that makes  the work possible (e.g., the production  of sub 50 micron
microvias); these lasers are used in the  manufacturing of high  density printed circuit  boards (‘‘PCBs’’)
found in the latest smart phones and  tablet computers.

Key laser applications include: semiconductor inspection; manufacturing of advanced  PCBs;  flat

panel  display manufacturing; solar cell production; medical and  bio-instrumentation; materials
processing; metals cutting and welding;  industrial process and quality control; marking; imaging and
printing; graphic arts and display; and,  research and  development. For example, ultraviolet  (‘‘UV’’)
lasers are enabling the move towards  miniaturization, which drives  innovation and growth  in many
markets. In addition, the advent of industrial  grade  ultrafast lasers continues to open up  new
applications for laser processing.

OUR STRATEGY

We  strive to develop innovative and proprietary  products and solutions that meet the  needs  of  our
customers and that are based on our core  expertise  in lasers and optical  technologies.  In pursuit  of our
strategy, we intend to:

(cid:127) Leverage our technology portfolio and application engineering to  lead the  proliferation of
photonics into broader markets—We will continue to identify opportunities in which our
technology portfolio and application engineering  can be used to offer  innovative solutions and
gain access to new markets. We plan to utilize  our  expertise to increase our  market  share in the
mid to high power material processing applications.

(cid:127) Optimize our leadership position in existing markets—There are a number of markets where we
have historically been at the forefront of technological development  and product deployment
and from which we have derived a substantial portion of our  revenues.  We plan to optimize our
financial returns from these markets.

(cid:127) Maintain and develop additional strong collaborative customer and industry relationships—We
believe that the Coherent brand name and reputation  for  product quality,  technical performance
and customer satisfaction will help us to further  develop our  loyal customer base. We plan to
maintain our current customer relationships  and develop new ones with customers  who are
industry leaders and work together with these customers  to design and develop innovative
product systems and solutions as they  develop new technologies.

(cid:127) Develop and acquire new technologies and market share—We will continue to enhance our

market position through our existing technologies  and  develop new  technologies through our
internal research and development efforts, as well as through the acquisition of additional
complementary technologies, intellectual property, manufacturing processes and product
offerings.

(cid:127) Streamline our manufacturing structure and improve our cost structure—We will focus on
optimizing the mix of products that we manufacture internally and externally. We will  utilize
vertical integration where our internal manufacturing process is considered proprietary and seek
to leverage external sources when the capabilities and cost structure are well  developed  and on a
path towards commoditization.

APPLICATIONS

Our products address a broad range  of applications that  we group  into  the following  markets:
Microelectronics, Materials Processing, OEM Components and Instrumentation  and Scientific Research
and Government Programs.

Microelectronics

Nowhere is the trend towards miniaturization  more prevalent than in the  Microelectronics market

where  smart phones, tablets, personal computers (‘‘PC’s’’), televisions (‘‘TV’s’’) and ‘‘wearables’’  are
driving advances in displays, integrated  circuits and  PCBs. In response to  market demands and
expectations, semiconductor and device manufacturers are continually seeking to improve  their process
and design technologies in order to manufacture smaller, more  powerful and more  reliable devices at
lower cost. New laser applications and  new laser  technologies are a key element  in delivering higher
resolution and higher precision at lower  manufacturing cost.

We  support three major markets in the microelectronics industry:  (1) flat panel display  (‘‘FPD’’)

manufacturing, (2) advanced packaging and interconnects (‘‘API’’) and (3) semiconductor front-end
(‘‘SEMI’’).

Microelectronics—flat panel display  manufacturing

The high-volume consumer market is  driving the production of  FPDs in applications such as
mobile phones, tablets, laptop computers, TVs and wearables. There are several types  of  established
and emerging displays based on quite  different  technologies, including liquid crystal (‘‘LCD’’)  and
organic light emitting diodes (‘‘OLED’’).  Each of these technologies utilize laser applications due to the
fact that lasers enable higher process speed,  better yield, improved battery life, lower cost and/or
superior display brightness and resolution.

Several display types require a high-density pattern  of  silicon  thin film  transistors  (‘‘TFTs’’).  If this
silicon is polycrystalline as opposed to amorphous, the display  performance  is greatly enhanced. In the
past, these polysilicon layers could only  be  produced on expensive special glass at high temperatures.
However, excimer-based processes, such  as  excimer  laser annealing  (‘‘ELA’’) have allowed high-volume
production of low-temperature polysilicon  (‘‘LTPS’’) on conventional glass substrates as  well as flexible
displays on plastic substrates. Our excimer lasers provide a unique solution for LTPS because they are
the only industrial-grade excimer lasers optimized for this application. The current state-of-the-art
product  for this application is our excimer  VYPER  laser, which  delivers  over 1000W of  power,  enabling
customers to scale to current Generation 5.5 &  6 substrates all the way up to Generation 8 sizes. These
systems are integral to the manufacturing process on all leading LTPS-based  smart phone displays, with
the highest commercially available pixel densities of greater  than 300 pixels per inch (ppi),  with the
current trends going to even higher ppi (>500 ppi) for  high end  smart phones, and  hold  the potential
for deployment in tablet display and  OLED TV manufacturing. Excimer based LTPS is  also enabling a
new generation of  flexible OLED displays which have already seen some  implementation in  leading
smart phones and wearables and are poised for rapid  growth in  the near future.

Our AVIA, Rapid, Talisker, Monaco  and  DIAMOND CO2 and CO lasers are also used in other

production processes for FPDs. These  processes include drilling, cutting, patterning, marking and  yield
improvement.

Microelectronics—advanced packaging and interconnects

After a wafer is patterned, there are then a host  of  other processes,  referred  to  as back-end

processing, which finally result in a packaged  encapsulated silicon chip. Ultimately, these  chips are then
assembled into finished products. The advent  of high-speed logic  and high-memory content devices has

8

caused chip manufacturers to look for  alternative technologies  to  improve  performance and lower
process costs. In terms of materials, this search  includes new types  of  materials, such  as low-k  and
thinner silicon. Our AVIA, Rapid, Talisker, Monaco and Matrix lasers provide economical  methods of
cutting and scribing these wafers while  delivering  higher yields than  traditional mechanical  methods.

There are similar trends in chip packaging  and  PCB manufacturing requiring more compact
packaging and denser interconnects.  In  many  cases, lasers  present  enabling technologies. For instance,
lasers are now the only economically  practical method for  drilling microvias in chip substrates  and in
both rigid and flexible PCBs. These microvias are tiny interconnects that are essential for  enabling
high-density circuitry commonly used  in  smart  phones, tablets  and advanced computing systems. Our
DIAMOND CO2 and AVIA diode pumped solid state  (‘‘DPSS’’) lasers  are the lasers of choice in this
application. The ability of these lasers  to  operate at very high repetition  rates  translates  into  faster
drilling speeds and increased throughput in  microvia processing  applications.  In  addition, multi-layer
circuit boards require more flexible production methods than conventional printing technologies can
offer, which has led to widespread adoption of laser direct imaging (‘‘LDI’’). Our Paladin  laser is used
for this application.

Lasers have also become a valuable tool in high-brightness (‘‘HB’’) light-emitting diode (‘‘LED’’)

manufacturing, improving LED performance and yield. LEDs have widespread  adoption as the light
source in all categories of LCD displays, from phones all the way to full size  TVs and  moving into
general lighting. Our lasers are used in  back-end processing of  HB-LEDs.

Microelectronics—semiconductor front-end

The term ‘‘front-end’’ refers to the production  of semiconductor  devices which occurs prior to

packaging.

As semiconductor device geometries decrease in size, devices  become increasingly  susceptible to
smaller defects during each phase of the  manufacturing  process and these defects can negatively impact
yield. One of the semiconductor industry’s responses to the increasing vulnerability of semiconductor
devices to smaller  defects has been to use defect  detection and inspection techniques that are  closely
linked to the manufacturing process.  For example, automated laser-based inspection systems are now
used to detect and locate defects as small as 0.01  micron,  which may not be observable by conventional
optical microscopes.

Detecting the presence of defects is only the first  step in  preventing their recurrence. After

detection, defects must be examined in  order to identify their size, shape and the process step in which
the defect occurred. This examination is  called defect  classification. Identification of the sources of
defects in the lengthy and complex semiconductor manufacturing process has become essential  for
maintaining high yield production. Semiconductor manufacturing has become an around-the-clock
operation and it is important for products  used  for inspection, measurement and  testing to be reliable
and  to have long lifetimes. Our Azure,  Paladin  and  Excimer lasers  are used to detect and characterize
defects in semiconductor chips.

Materials processing

Lasers are widely accepted today in many  important industrial manufacturing  applications
including cutting, welding, joining, drilling, perforating, and marking of metals and nonmetals.  We
supply high-power lasers for metal processing and low-to-medium power lasers  for laser  marking,
nonmetals processing and precision micromachining.

Our high power industrial laser systems  are  used  for cutting,  welding,  cladding and hardening  of

metals, as well as other materials processing applications.

9

Our Semiconductor business provides higher power arrays  with powers in  excess of 50 kilowatts
through proprietary cooling and stacking  technology. This  unique  technology provides the engine for
both our Highlight direct diode systems as well  as our Highlight multi-kilowatt  class fiber lasers. Our
differentiated fiber laser design offers our customers a higher level of  integration and  additional
options for product serviceability. Our fiber  lasers are  used  for  metal cutting, cladding,  welding  and
additive manufacturing applications.

Complementing our high power solid state  lasers is our industry leading  DIAMOND E1000  CO2

laser. This laser remains in high demand  due to its high power, small size  and completely sealed
design—all ideal for materials processing.

With the broadest product portfolio in the  laser industry, we  offer solutions for  almost any

application on any material to our customers. Combining  the high power Direct Diode,  Fiber and CO2
products with our META flatbed cutting  tool provides  a strong,  compelling  four-pronged approach  to
meeting  the needs of our diverse high power materials processing customers.  We are  vertically
integrated with world class diode and active fiber  manufacturing,  which makes us very well positioned
to succeed in both the near and long  term in the  high power fiber laser  market.

We  also participate in the low to medium power area, including such  applications  as the cutting,
drilling  and joining of a host of materials using our DIAMOND CO and CO2 lasers; Highlight fiber
array product (‘‘FAP’’) semiconductor lasers in OEM opportunities and direct  end user applications
with META cutting tools; applications  including cutting, perforating and scoring of paper, thin metals
and packaging materials; and various cutting and patterning  applications in the textile, wood  and sign
industries. In the specific area of textiles  and clothing,  our DIAMOND lasers service older applications,
such as cutting complex shapes in leather for footwear,  as well  as newer applications such as creating
detailed fade patterns on designer denims.

Laser marking and coding are generally considered part of the  precision materials  processing
applications market for which we remain a leading supplier. The optimum choice of laser depends on
the material being marked, whether it  is  a surface mark (engraved) or a sub-surface  mark,  and the
specific  economics of the application. Our DIAMOND J, C  and GEM Series  of CO2 lasers provide
many  systems manufacturers with a reliable  cost effective  source  for marking and  engraving on
non-metals. In addition, our Matrix and  Helios product  lines of reliable, compact  and low-cost  DPSS
lasers provide an ideal solution for marking of  other  materials in high volume manufacturing.

With our large portfolio of Ultrafast  laser  technology, we serve customers with a  variety of  laser

micromachining solutions, including our  Integrated  Optics  Systems  group which will develop sub
systems and new applications in the fast growing micro materials processing market.

OEM components and instrumentation

Instrumentation is one of our more mature commercial applications. Representative  applications
within this market include bio-instrumentation, medical OEMs, graphic arts and display and  machine
vision.  We also support the laser-based  instrumentation market with a range of laser-related
components, including diode lasers for optical pumping. Our  OEM component business includes  sales
to other, less integrated laser manufacturers participating in OEM markets  such as materials
processing, scientific, and medical.

Bio-instrumentation

Bio-instrumentation applications for  lasers  include  bio-agent  detection for  point source and
standoff detection of pathogens or other bio-toxins;  confocal microscopy for  biological  imaging that
allows researchers and clinicians to visualize cellular and subcellular structures and processes with an
incredible amount of detail; DNA sequencing that  provides automation and  data  acquisition  rates  that

10

would be impossible by any other method; drug discovery—genomic and proteomic analyses that enable
drug discovery to proceed at very high throughput rates; and flow cytometry for  analyzing  single  cells or
populations of cells in a heterogeneous mixture, including blood samples. Our OBIS,  Flare, Galaxy,
Sapphire, BioRay and Genesis lasers  are  used  in several  bio-instrumentation applications.

Medical Therapy

We  sell a variety of components and lasers  to  medical  laser companies  in end-user applications
such as ophthalmology, aesthetic, surgical,  therapeutic  and dentistry. Our DIAMOND series CO2 lasers
are widely used in ophthalmic, aesthetic and surgical markets.  We have  a  leading position in Lasik and
photorefractive keratectomy surgery methods with our ExciStar XS excimer laser  platform. We also
provide ultrafast lasers for use in cataract surgery, a growing applications space.

The unique ability of our optically pumped semiconductor lasers  (‘‘OPSL’’) technology to match a
wavelength to an application has led to the  development of a high-power yellow (577nm) laser for  the
treatment of eye related diseases, such as  Age  Related Macular Degeneration and  retinal diseases
associated with diabetes. The 577nm wavelength was designed to match the peak in  absorption of
oxygenated hemoglobin thereby allowing  treatment to occur  at  a  lower  power level, and  thus reducing
stress and heat-load placed on the eye with traditional  green-based  (530nm)  solid  state lasers. Other
applications where our OBIS, Genesis and Sapphire series of  lasers  are  used include  the retinal
scanning market in diagnostic imaging  systems as well  as new ground breaking in-vivo  imaging.

Scientific research and government programs

We  are widely recognized as a technology innovator and the scientific market has historically
provided an ideal ‘‘test market’’ for our leading-edge innovations. These have  included ultrafast lasers,
DPSS lasers, continuous-wave (‘‘CW’’)  systems, excimer gas lasers  and water-cooled  ion gas  lasers. Our
portfolio of lasers that address the scientific research market is broad and includes  our  Chameleon,
COMPexPro, Evolution, Fidelity, Legend, Libra, MBD,  MBR, Monaco, Vitara, Mephisto, Mira and
Verdi  lasers. Many of the innovations and  products pioneered  in the scientific marketplace have
become  commercial successes for both  our OEM customers and us.

We  have a large installed base of scientific lasers  which are used in a wide  range of applications

spanning virtually every branch of science  and engineering.  These  applications include  biology and life
science, engineering, physical chemistry and physics. Most of these applications require the  use of
ultrafast lasers that enable the generation  of pulses short enough to be measured in femto- or
attoseconds (10(cid:3)15 to 10(cid:3)18 seconds). Because of these very short pulse durations,  ultrafast lasers
enable the study of fundamental physical and chemical  processes with temporal resolution unachievable
with any other tool. These lasers also  deliver very  high  peak power and  large bandwidths, which can be
used to generate many exotic effects. Some of these are now finding their way into mainstream
applications, such as microscopy or materials processing. The use of  ultrafast lasers such as the
Chameleon in microscopy is now a common  occurrence in bio-imaging  labs, and they have become a
crucial tool in modern brain research. We recently released  a new  product called the Chameleon
Discovery targeted to this market.

FUTURE TRENDS

Microelectronics

Lasers  are widely used in mass production microelectronics applications largely because they
enable entirely new application capabilities  that cannot  be  realized by any other known means. These
laser-based fabrication and testing methods provide a level of precision, typically  on a micrometer and
nanometer level, that are unique, faster, are touch free, deliver superior end products, increase yields,
and/or cut production costs. We anticipate  this trend  to  continue, driven primarily by the increasing

11

sophistication and  miniaturization of consumer electronic  goods and their  convergence  via the  internet,
resulting in increasing demand for better  displays, more bandwidth and memory, and  all  packaged into
devices which are lighter, thinner and consume less  power. Although this market follows the macro-
economic trends and carries inherent  risks,  we believe  that we are well  positioned to continue  to
capitalize on the current market trends  and that we  will see continued increased adoption of our solid-
state, CO2, fiber, direct diode and excimer lasers, as all  these  lasers  enable  entirely new applications,
performance improvements and reduced  process  costs.

Excimer laser based LTPS is a key technology for producing high  resolution  OLED displays in
general and flexible OLED displays in particular. We believe  we  are  well positioned to take advantage
of the rapid growth that is projected  for OLED  displays in  smart phones  and other mobile  devices over
the next several years with our Vyper and  LineBeam systems.

CO2, Avia, Matrix, Rapid, Talisker, Helios and direct  diode  lasers all seem  aligned with the  need

for related FPD touch panel, film cutting,  light guide  technology, repair, frit welding, as well  as
sapphire and glass-cutting applications.

The trend for thinner and lighter devices  is impacting the glass substrates  used in today’s mobile
devices requiring thinner glass with higher  degrees of mechanical  strength and scratch resistance. This
trend also includes use of sapphire instead of glass. Mechanical  means of cutting  these glass and
sapphire pieces are no longer adequate to meet future  requirements and we expect  lasers to play an
increased role. Our CO, CO2, Monaco and Rapid lasers are well positioned to take advantage  of  this
trend.

Semiconductor devices look set to continue  Moore’s  Law,  shrinking device geometries  for at least

another decade, as well as expanding  vertically  into new 3D  structures. As a result we believe our  many
UV laser sources (such as Azure, Paladin,  Avia, Rapid,  ExiStar and  Matrix) will continue to find
increasing adoption, since their unique  optical properties align well  with the  process demands of a
nanometer scale world.

The same lasers plus Monaco, Rapid  FX, CO  and CO2 are also widely adopted for back end
Advanced Packaging and Interconnect  (API)  applications.  With  dimension  roadmaps showing a decade
of dimension shrink on PCBs, interconnects, Silicon &  LED  scribe widths  and wafer thickness,  we
believe that our portfolio of lasers aligns  well with these demands as well as new processes that seem
likely to be enabled by our lasers, to meet  the increasing demands and decreasing tolerances of these
markets.

Materials processing

The market for low to medium power CO2, solid state and semiconductor lasers  used  in industrial
materials processing is very diverse. New  product introductions such  as our Diamond  J-series CO2 and
CO lasers continue to support our growth in this area. These lasers represent a  cost-effective
manufacturing solution for cutting, joining, marking and engraving of  non-metal materials including
marking/coding, flat bed cutting, engraving, as well as the production of capital equipment  for apparel
and leather goods  manufacturing.

The market for kW class fiber lasers  has  seen strong growth in recent  years,  replacing legacy
multi-kW CO2 lasers in metal cutting and other applications. This trend will  likely continue into the
future. The favorable cost of ownership  of high  power  diode and fiber lasers has  expanded  their use in
a number of metal processing applications in  addition  to  cutting.  They have  seen adoption in  welding
and brazing applications as well as newer  growth areas in  additive manufacturing like  cladding and
3D printing. We believe we are well  positioned to benefit from  these large and  growing  markets  with
our  line of kW fiber and diode lasers.

12

We  have developed an expanded portfolio of  lasers with  a broad spectrum  of wavelengths  and
power levels, enabling optimum solutions for virtually  every metal and non-metal  material  type. At the
same time, the higher reliability of these  products has lowered the  cost of ownership.

OEM components and instrumentation

The bio instrumentation market is on  a steady path in the most  important areas: microscopy, flow

cytometry and DNA sequencing, which  all are enjoying  solid  research funding on  a worldwide basis
with some local variations. In this field, our OPSL technology gives us differentiated products  at a
number of important wavelengths. This  advantage coupled with strong  focus on  meeting our  customers’
demands  for more compact and cost  effective sources has made us very successful and we  expect that
to continue. Our OPSL technology resulted in the first truly continuous wave  solid-state  UV laser
which  enables the use of UV in a clinical as well  as a research  environment.

In the medical therapeutic area, we see solid business with several opportunities for  growth. We
supply excimer lasers used in refractive eye surgery  and are  actively involved in further developments in
laser vision correction including the use of ultrafast lasers in applications  such as  laser cataract surgery
where  higher precision and use of advanced implants enable better and more reliable  patient  outcomes.
Laser cataract surgery is still at a relatively  early stage of adoption and is expected to see continued
growth over the next several years. We  also have opportunities  in dental  procedures for  both  hard and
soft tissue ablation, with greatly improved patient  comfort and outcome. In the area of
photocoagulation, our Genesis OPSL  yellow lasers  are being used as  the wavelength  is particularly
suitable  for the treatment of blood vessels.  In  aesthetic laser procedures,  we are  an OEM supplier of
CO2 and semiconductor lasers to the major  manufacturers  of equipment  used  in the latest procedures
in dermatology and hair removal.

Scientific research and government programs

Worldwide scientific funding seems very  stable overall, with  some regions growing and others just
holding their current level. Bright spots  include the strong push  in neuroscience to better understand
how the brain functions. Lasers play a very  important  role in  imaging brain  structure as  well as tracking
activity in animal brains using techniques  such  as optogenetics. We  believe that our  current and
upcoming products are well positioned  to  take advantage  of  this exciting opportunity.  In  physics  and
chemistry applications, our recent product introductions of high performance  and industrially hardened
ultrafast products have been very well received. While this is a  very competitive market, we  expect that
our  new products will position us for  growth.

In addition to products we provide, we  invest  routinely in the  core technologies needed to create
substantial differentiation for our products in the marketplace. Our semiconductor,  crystal, fiber and
large form factor optics facilities all maintain an external  customer base providing value-added
solutions. We direct significant engineering efforts  to  produce  unique solutions targeted  for internal
consumption. These investments, once  integrated into our broader  product portfolio, provide  our
customers with uniquely differentiated solutions  and the  opportunity  to  substantially enhance  the
performance, reliability and capability  of  the products we  offer.

TECHNOLOGIES

Diode-pumped solid-state lasers

DPSS lasers use semiconductor lasers  to pump  a crystal to produce  a laser beam.  By changing the
energy, optical components and the types  of crystals used in the laser, different  wavelengths and types
of laser light can be produced.

The efficiency, reliability, longevity and relatively low cost  of DPSS lasers make  them ideally suited

for a wide range of OEM and end-user applications, particularly those requiring 24-hour  operations.
Our DPSS systems are compact and  self-contained sealed  units. Unlike  conventional tools and other
lasers, our DPSS lasers require minimal  maintenance since they  do not have internal controls or
components that require adjusting and cleaning to maintain consistency.  They  are also less affected by
environmental changes in temperature  and humidity,  which can alter alignment and inhibit performance
in many systems.

We  manufacture a variety of types of  DPSS  lasers for different applications including
semiconductor inspection; advanced packaging  and  interconnects; laser  pumping; spectroscopy;
bio-agent detection; DNA sequencing; drug discovery;  flow cytometry; forensics; computer-to-plate
printing; entertainment lighting (display);  medical; rapid  prototyping and marking, welding, engraving,
cutting and drilling.

Fiber lasers

Fiber  lasers use semiconductor lasers  to  pump a doped  optical  fiber to produce a  laser beam. The

unique  features of a fiber laser make them suitable for  producing high power, continuous wave laser
beams. We introduced a multi kilowatt fiber  laser platform in fiscal 2015. Our fiber  laser design has
several unique features including a modular design  for  improved serviceability and diode bar based
pumping. Due to packaging efficiency,  diode bars reduce the overall cost  of a fiber laser.  Some  of the
most critical components inside a fiber laser include the gain  fiber itself  and the  diodes providing  the
pump power. We are well positioned  as  a fiber laser supplier since we are  vertically integrated  with
respect to these key technologies; we use  diode bars and fiber  manufactured in-house. We  plan to
continue to drive cost reduction in our diode laser pumps and demonstrate the scalability  of  the
platform by moving up the power scale into the multi kilowatt regime. This platform will address the
large growing high power metal cutting  and joining  market.

Gas lasers (CO, CO2, Excimer, Ion)

The breadth of our gas laser portfolio is industry leading, encompassing CO, CO2, excimer and ion
laser technologies. Gas lasers derive their name from the  use of one or more gases as a  lasing medium.
They collectively span an extremely diverse  and  useful emission range, from  the very deep ultraviolet to
the far infrared. This diverse range of  available wavelengths,  coupled with high optical output power,
and an abundance of other attractive characteristics, makes gas lasers extremely useful and popular for
a variety of microelectronics, scientific, medical therapeutic and materials processing applications.

15

Optically Pumped Semiconductor Lasers  (‘‘OPSL’’)

Our OPSL platform is a surface emitting semiconductor  laser that is  energized or pumped by a

semiconductor laser. The use of optical  pumping circumvents  inherent power scaling  limitations of
electrically pumped lasers, enabling very high powered devices. A wide range of wavelengths can  be
achieved by varying the semiconductor materials  used  in the device and changing the  frequency  of the
laser beam using techniques common  in solid state  lasers. The platform leverages high reliability
technologies developed for telecommunications and produces  a  compact, rugged, high power,
single-mode laser.

Our OPSL products are well suited to  a wide range  of applications, including the

bio-instrumentation, medical therapeutics and  graphic  arts and display markets. We continue to expand
our  ultraviolet version of the OPSL platform called the Genesis,  which was developed for the
bio-instrumentation market.

Semiconductor lasers

High power edge emitting semiconductor diode lasers  use the  same  principles as widely-used CD

and DVD lasers, but produce significantly higher power levels. The advantages of this type  of  laser
include smaller size, longer life, enhanced  reliability and greater efficiency. We  manufacture a wide
range of discrete semiconductor laser products  with wavelengths ranging from 650nm to over  1000nm
and output powers ranging from 1W  to  over 100W, with  highly  integrated  products in the kW range.
These products are available in a variety  of industry standard form factors including the following:  bare
die, packaged and fiber coupled single emitters and bars,  monolithic  stacks and fully integrated
modules with microprocessor controlled units that contain power supplies and  active  coolers.

Our semiconductor lasers are used internally as  the pump lasers in DPSS,  fiber  and OPSL

products that are manufactured by us,  as  well  as a wide variety of  external  medical,  OEM, military and
industrial applications, including aesthetic (hair removal,  cosmetic dentistry), graphic arts,  counter
measures, rangefinders, target designators,  cladding, hardening and plastic welding.

Ultrafast  (‘‘UF’’) Lasers

Ultrafast  lasers are lasers generating light pulses with  durations  of  a  few femtoseconds
(10(cid:3)15 seconds) to a few tens of picoseconds  (10(cid:3)11 seconds). These types of lasers are used for
medical, advanced microelectronics and  materials processing applications as well as scientific research.
UF laser oscillators generate a train of  pulses at 50-100 MHz, with peak powers of tens of  kilowatts,
and UF laser amplifiers generate pulses  at 1-2000 kHz, with peak powers up to several Terawatts.

The extremely short duration of UF  laser pulses  enables temporally resolving fast events like the
dynamics of atoms or electrons. In addition,  the high peak power enables  so-called non-linear effects
where  several photons can be absorbed by a molecule at  the same time. This  type of process enables
applications like multi-photon excitation microscopy or UF ablation of materials with high  precision
and minimal thermal damage. The use  of  our ultrafast lasers in applications outside  science has been
growing rapidly over the last several years, particularly  in  microelectronics and  materials processing
applications.

SALES AND MARKETING

We  primarily market our products in the United States through a direct sales force.  We  sell
internationally through direct sales personnel located  in Canada, France, Germany, Italy, Japan, the
Netherlands, China, South Korea, Taiwan  and the  United  Kingdom, as well  as through independent
representatives in certain jurisdictions around  the world.  Our foreign sales are  made principally to
customers in South Korea, Japan, Germany, China  and other European and Asia-Pacific countries.

16

Foreign sales accounted for 76% of our  net sales  in fiscal 2016, 73% of our net sales in  fiscal 2015 and
74% of our net sales in fiscal 2014. Sales made to independent representatives and distributors are
generally priced in U.S. dollars. A large portion of  foreign sales that  we  make directly  to  customers are
priced in local currencies and are therefore subject  to  currency  exchange fluctuations. Foreign sales are
also subject to other normal risks of  foreign operations such as  protective tariffs, export and import
controls and political instability.

We  had one customer, Advanced Process Systems  Corporation, who contributed more than 10% of

revenue during fiscal 2016, 2015 and 2014.  We  had another major customer, Japanese Steel
Works, Ltd., who contributed more than 10% of revenue during fiscal 2016.

To support our sales efforts we maintain and continue  to  invest  in a number of applications centers

around the world, where our applications  experts  work closely with  customers on developing laser
processes to meet their manufacturing  needs. The applications span a  wide  range, but are mostly
centered around the materials processing and  microelectronics  markets. Locations include several
facilities in the US, Europe and Asia.

We  maintain customer support and field service  staff  in major  markets within the United States,
Europe, Japan, China, South Korea, Taiwan and other Asia-Pacific countries. This organization works
closely with customers, customer groups and  independent representatives in servicing equipment,
training customers to use our products and exploring additional  applications of our technologies.

We  typically provide parts and service warranties  on our lasers, laser-based systems,  optical and
laser components and related accessories and services.  Warranties on some of our products  and services
may be shorter or longer than one year.  Warranty reserves, as  reflected on our consolidated balance
sheets, have generally been sufficient  to  cover product warranty repair and replacement costs.  The
weighted average warranty period covered is approximately  15 months.

RESEARCH AND DEVELOPMENT

We  are constantly developing and introducing  new products  as well  as improving and  refining
existing products to better serve the  markets we  participate in. Our development efforts  are focused on
designing and developing products, services and solutions that  anticipate  customers’  changing needs and
emerging technological trends. Our efforts are also focused on  identifying the  areas where we believe
we can make valuable contributions.  Research and development expenditures for fiscal 2016 were
$81.8 million, or 9.5% of net sales compared to $81.5  million,  or  10.2% of net  sales for fiscal 2015  and
$79.1 million, or 10.0% of net sales for  fiscal 2014. We work closely with  customers, both  individually
and through our sponsored seminars,  to  develop products  to  meet customer application and
performance needs. In addition, we are  working with  leading research and educational institutions to
develop new photonics based solutions.

MANUFACTURING

Strategies

One  of our core manufacturing strategies is to tightly  control our  supply of key parts, components,

sub-assemblies and outsourcing partners.  We  primarily utilize vertical integration when  we have
proprietary internal capabilities that  are  not  cost-effectively available from  external sources. We  believe
this  is essential to maintain high quality products  and enable rapid development and  deployment  of
new products and technologies. We provide  customers with 24-hour technical expertise and quality that
is International Organization for Standardization (‘‘ISO’’)  certified at our principal manufacturing sites.

Committed to quality and customer satisfaction, we  design and produce many  of our  own
components and sub-assemblies in order to retain quality and performance control.  We have also

17

outsourced certain components, sub-assemblies and finished goods  where we can maintain our high
quality standards while improving our cost structure.

As part of our strategy to increase our market share and  customer support  in Asia  as well as  our

continuing efforts to manage costs, we have transferred the production of additional products  into  both
of our Singapore and Malaysia factories. In addition,  we expanded our repair  activities in  our China
and South Korea operations and also  opened a tube refurbishment manufacturing site  in South Korea.
This has allowed us to reduce service  response time and inventories, providing benefits  to  us  and to our
customers. We have also established an International Procurement Office in  Singapore and have been
increasing our sourcing of materials from  Asia to reduce  material costs on a global  basis. In fiscal 2015,
we increased  our vertical integration  capabilities with the asset  acquisition of the  Tinsley Optics
business from L-3 Communications Corporation.

We  have designed and implemented proprietary manufacturing tools, equipment and  techniques in

an effort to provide products that differentiate us from  our competitors.  These proprietary
manufacturing techniques are utilized in  a number of our product  lines including  our gas laser
production, crystal growth, beam alignment as well as the  wafer growth for our  semiconductor  and
optically pumped semiconductor laser  product family.

Raw materials or sub-components required in the  manufacturing  process are generally available
from several sources. However, we currently purchase several key components  and materials, including
exotic materials, crystals and optics, used  in the manufacture of our  products  from sole source or
limited source suppliers. We also purchase assemblies and turnkey solutions from  contract
manufacturers based on our proprietary  designs. We rely on  our own production and  design capability
to manufacture and specify certain strategic components,  crystals, fibers, semiconductor lasers,  lasers
and laser based systems.

For a  discussion of the importance to our business of, and the risks attendant  to  sourcing, see
‘‘Risk Factors’’ in item 1A—‘‘We depend on  sole source  or limited source  suppliers, both internal  and
external, for some of our key components  and  materials, including  exotic  materials, certain cutting-edge
optics and crystals, in our products, which  make us susceptible to supply shortages or price  fluctuations
that could adversely affect our business.’’

Operations

Our products are manufactured at our sites in  Santa  Clara, Sunnyvale  and  Richmond, California;

Wilsonville, Oregon; East Hanover, New Jersey;  Bloomfield, Connecticut; Salem, New  Hampshire;
L¨ubeck, Germany; G¨ottingen, Germany; Kaiserslautern, Germany; Glasgow, Scotland; YongIn-Si, South
Korea; Kallang Sector, Singapore; and Penang, Malaysia. In  addition,  we also use contract
manufacturers for the production of  certain assemblies and turnkey  solutions.  Our ion gas lasers, a
portion of our DPSS lasers that are used  in microelectronics, scientific research and  materials
processing applications, semiconductor lasers, OPS  lasers, fiber lasers and  ultrafast scientific lasers are
manufactured at our Santa Clara, California site.  Our laser  diode  module products, laser
instrumentation products, test and measurement equipment  products are manufactured  in Wilsonville,
Oregon. We manufacture exotic crystals in East Hanover,  New  Jersey and both active and passive fibers
are manufactured in our Salem, New  Hampshire facility. Our CO2 and CO gas lasers are manufactured
in Bloomfield, Connecticut. We manufacture  our  LMT products in  Bloomfield, Connecticut and
Singapore. We manufacture a portion of our DPSS lasers used  in microelectronics and  OEM
components and instrumentation applications in  L¨ubeck, Germany. We manufacture a  portion of our
DPSS lasers used in microelectronics,  OEM components and  instrumentation and materials processing
applications in Kaiserslautern, Germany.  Our  excimer  gas laser products are manufactured  in
G¨ottingen, Germany. We refurbish excimer tubes at our  manufacturing  site in South Korea. We
manufacture the fiber-based lasers and a  portion  of our DPSS lasers used in  microelectronics  and

18

scientific research applications in Glasgow, Scotland. Our facility in Sunnyvale, California grows the
aluminum-free materials that are incorporated into our semiconductor  lasers. Our facility  in Richmond,
California manufactures large form factor optics for our Linebeam excimer laser annealing systems. We
have transferred several products and subassemblies for manufacture at our Singapore and  Malaysia
facilities and are continuing to transfer  additional product manufacturing to Singapore and Malaysia as
part of our worldwide manufacturing  cost  reduction  strategy.

INTELLECTUAL PROPERTY

We  rely  on a combination of patent, copyright, trademark  and trade secret laws and restrictions on

disclosure to protect our intellectual property rights. As of  October 1, 2016, we held  approximately
565 U.S. and foreign patents, which expire from  2016 through 2032  (depending on  the payment  of
maintenance fees) and we have approximately 133  additional  pending patent applications that have
been filed. The issued patents cover  various  products in  all of the major  markets  that  we serve.

For a  discussion of the importance to our business of, and the risks attendant  to  intellectual
property rights, see ‘‘Risk Factors’’ in  Item 1A—‘‘We  may not be able to protect our proprietary
technology which could adversely affect  our competitive advantage’’  and ‘‘We may, in the future,  be
subject to claims or litigation from third parties, for claims of  infringement of their proprietary  rights or
to determine the scope and validity of our  proprietary  rights or the  proprietary rights of competitors or
other rights holders. These claims could result in costly litigation and the diversion of our technical and
management personnel. Adverse resolution of litigation may  harm  our operating results or financial
condition.’’

COMPETITION

Competition in the various photonics  markets  in which we provide products is very intense. We

compete against a number of large public  and private  companies including CVI  Melles Griot,
Novanta Inc., IPG Photonics Corporation, Lumentum  Holdings Inc., MKS  Instruments,  Inc., and
Trumpf GmbH, as well as other smaller  companies. We compete globally based  on our broad product
offering, reliability, cost, and performance  advantages for  the widest range of commercial and scientific
research applications. Other considerations by our customers  include warranty, global  service  and
support and distribution.

BACKLOG

At fiscal 2016 year-end, our backlog of orders scheduled for  shipment (within one year) was
$605.3 million compared to $309.5 million  at fiscal 2015 year-end. By segment, backlog for  SLS was
$515.2 million and $219.3 million, respectively,  at fiscal 2016 and 2015  year-ends.  Backlog for  CLC was
$90.1 million and $90.2 million, respectively,  at fiscal 2016  and 2015  year-ends.  The increase in  SLS
backlog from fiscal 2015 to fiscal 2016 year-end is  primarily  due to timing  of large excimer laser
annealing system orders, net of shipments,  for the  flat panel display market, which explains the  increase
in overall company backlog as well. Orders used to compute backlog are generally cancelable and,
depending on the notice period, are subject to rescheduling by our customers without  substantial
penalties. Historically, we have not experienced a significant rate of cancellation or rescheduling,
though we cannot guarantee that the  rate of cancellations or rescheduling will not increase  in the
future.

SEASONALITY

We  have historically experienced decreased revenue  in the first  fiscal  quarter  compared to other
quarters in our fiscal year due to the impact of  time off and business  closures at our facilities and  those
of many of our customers due to year-end  holidays. For example over the  past 10 years we have noted,

19

excluding certain recovery years, our  first  fiscal  quarter revenues have ranged 2%-12% below the fourth
quarter of the prior fiscal years. This historical pattern should not be considered a reliable indicator of
the Company’s future net sales or financial  performance.

EMPLOYEES

As of fiscal 2016 year-end, we had 2,787 employees.  Approximately  396 of our employees  are

involved in research and development;  1,786  of  our  employees are  involved in  operations,
manufacturing, service and quality assurance; and 605 of our employees are involved in sales,  order
administration, marketing, finance, information technology, general  management and other
administrative functions. Our success  will  depend in large  part upon our ability to attract  and retain
employees. We face competition in this regard from  other  companies, research and academic
institutions, government entities and  other organizations. We consider  our relations with our employees
to be good.

ACQUISITIONS

On November 7, 2016, we acquired Rofin, one of the world’s leading  developers and

manufacturers of high-performance industrial laser sources and laser-based solutions and components.
See ‘‘Recent Developments’’ for further  discussion of the  acquisition  and  the  Credit Agreement.

In July 2015, we acquired certain assets  of Raydiance, Inc. (‘‘Raydiance’’) for approximately

$5.0 million, excluding transaction costs.  Raydiance manufactured complete tools and lasers  for
ultrafast processing systems and subsystems  in the precision micromachining processing  market.  The
Raydiance assets have been included  in our Specialty Lasers and  Systems  segment.

In July 2015, we acquired the assets and certain liabilities of the  Tinsley Optics  (‘‘Tinsley’’)
business from L-3 Communications Corporation for approximately $4.3 million, excluding transaction
costs. Tinsley is a specialized manufacturer  of high precision optical  components and  subsystems sold
primarily in the aerospace and defense industry. Tinsley manufactures the large form  factor optics for
our  excimer laser annealing systems. The  Tinsley  assets have been included in our  Specialty  Lasers and
Systems segment.

Please refer to ‘‘Note 3. Business Combinations’’ of Notes to  Consolidated Financial Statements

under Item 15 of this annual report for further  discussion of recent acquisitions completed.

GOVERNMENT REGULATION

Environmental regulation

Our operations are subject to various federal,  state, local and foreign environmental regulations
relating to the use, storage, handling  and disposal of  regulated materials, chemicals, various radioactive
materials and certain waste products.  In the  United States, we are subject to the federal regulation and
control of the Environmental Protection  Agency.  Comparable  authorities are involved  in other
countries. Such rules are subject to change by the governing  agency  and we monitor those changes
closely. We expect all operations to meet  the legal and regulatory environmental  requirements and
believe that compliance with those regulations will  not  have a material  adverse effect  on our capital
expenditures, earnings and competitive and financial  position.

Although we believe that our safety procedures for  using,  handling, storing and disposing  of such

materials comply with the standards required by federal and state laws and regulations, we cannot
completely eliminate the risk of accidental contamination or  injury from these  materials. In  the event of
such an accident involving such materials,  we could be liable for  damages and such liability could
exceed the amount of our liability insurance  coverage  and the resources of our business.

20

We  may face the potential of increasing  complexity  in our product  designs and procurement
operations due to the evolving nature  of  product compliance standards. Those  standards may impact
the material composition of our products entering specific markets. Such regulations  went  into  effect  in
the European Union (‘‘EU’’) in 2006, (The  Restriction of Hazardous Substances Directive (RoHS)) and
2007 (Registration, Evaluation, Authorisation  and Restriction of Chemicals (REACH)), and China in
2007 (Management Methods for Controlling Pollution Caused by  Electronic  Information Products
Regulation (China-RoHS)), and the US  Dodd-Frank  Wall Street  Reform and Consumer Protection Act
of 2010. Furthermore, we could face  costs and  liabilities in connection with product take-back
legislation. Beginning in 2006, the EU  Waste Electrical and Electronic  Equipment Directive made
producers of electrical goods financially responsible for  specified collection, recycling, treatment and
disposal of past and future covered products. Similar laws are  now pending in various  jurisdictions
around the world, including the United  States.

Environmental liabilities

Our operations are subject to various laws  and  regulations governing  the environment,  including
the discharge of pollutants and the management and disposal  of hazardous substances. As a result of
our  historic as well as on-going operations,  we could incur substantial costs,  including remediation
costs. The costs under environmental laws and the timing  of these costs are  difficult  to  predict. Our
accruals for such costs and liabilities may  not be adequate because the estimates on  which the accruals
are based depend on a number of factors including  the nature of the matter, the  complexity of the site,
site geology, the nature and extent of  contamination, the type  of remedy, the outcome  of  discussions
with regulatory agencies and other Potentially  Responsible Parties (PRPs) at  multi-party sites  and the
number and financial viability of other PRPs.

We  further discuss the impact of environmental regulation  under ‘‘Risk  Factors’’ in  Item 1A—
‘‘Compliance or the failure to comply with current and future  environmental regulations  could  cause us
significant expense.’’

SEGMENT INFORMATION

We  are organized into two operating  segments:  SLS  and  CLC. This segmentation reflects  the
go-to-market strategies for various products and markets.  While  both segments deliver cost-effective
photonics solutions, SLS develops and manufactures configurable, advanced performance products
largely serving the microelectronics, scientific research and government programs and OEM
components and instrumentation markets.  The size  and complexity of many of the SLS products
require service to be performed at the customer  site by  factory-trained field service engineers. CLC
focuses on higher volume products that  are  offered  in set configurations.  The product  architectures are
designed for easy exchange at the point of use such  that  substantially all product  service  and repairs are
based upon advanced replacement and  depot (i.e., factory) repair. CLC’s primary  markets  include
materials processing, OEM components  and instrumentation and microelectronics.

We  have identified SLS and CLC as  operating segments for which  discrete financial information
was available. Both units have dedicated engineering,  manufacturing,  product business management  and
product  line management functions. A  small portion  of our outside revenue is  attributable to projects
and recently developed products for which  a segment has  not  yet been determined. The associated
direct and indirect costs are presented in the  category  of  Corporate  and other,  along with  other
corporate costs.

FINANCIAL INFORMATION ABOUT  FOREIGN AND DOMESTIC OPERATIONS AND  EXPORT

SALES

Financial information relating to foreign and domestic operations  for fiscal years 2016, 2015  and

2014, is set forth in Note 15, ‘‘Segment  and Geographic  Information’’ of our Notes to Consolidated
Financial Statements under Item 15 of  this annual report.

ITEM 1A. RISK FACTORS

You should carefully consider the followings  risks when considering  an investment in our  Common
Stock. These risks could materially affect our business, results of operations or financial  condition, cause  the
trading price of our Common Stock to  decline  materially or  cause our actual results  to differ materially
from those expected or those expressed in any forward-looking statements  made by us. These  risks  are not
exclusive, and additional risks to which we are subject include,  but  are not limited to, the factors mentioned
under ‘‘Forward-Looking Statements’’  and  the risk of our businesses described elsewhere in this annual
report. Additionally, these risks and uncertainties described herein are  not  the only  ones  facing  us.  Other
events  that we do not currently anticipate or that we currently deem  immaterial  also may affect our business,
results of operations or financial condition.

RISKS RELATED TO THE MERGER WITH ROFIN

We may  not be able to integrate the business  of Rofin successfully with  our own  or realize  the anticipated
benefits of the merger.

We  will be required to devote significant management attention and resources to integrating our

business practices with those of Rofin. Potential difficulties  that we may  encounter as part of the
integration process include the following:

(cid:127) the inability to successfully combine our business with Rofin  in a  manner that permits the

combined company to achieve the full synergies and other benefits  anticipated  to  result from the
merger;

(cid:127) complexities associated with managing  the combined businesses, including  difficulty addressing
possible differences in corporate cultures and management philosophies and the challenge  of
integrating products, services, complex and different information technology systems, technology,
networks and other assets of each of  the companies in  a cohesive  manner; and

(cid:127) potential unknown liabilities and unforeseen increased expenses or delays related  to  the merger

and the integration of Rofin, including as a result of the  requirement for holding separate
Rofin’s business located in Hull, England.

In addition, we have operated independently prior to the  merger and it is  possible  that  the

integration process following the merger  could result in:

(cid:127) diversion of the attention of our management;  and

(cid:127) the disruption of, or the loss of momentum in, our business or inconsistencies in  standards,
controls, procedures or policies, any of which  could adversely affect  our ability to maintain
relationships with customers, suppliers,  employees and other constituencies or our ability to
achieve the anticipated benefits of the merger, or could reduce  our earnings or  otherwise
adversely affect our business and financial results.

(cid:127) In  addition, prior to the merger, Rofin’s business  faced risks and uncertainties, including those
faced by our business and identified  below.  Rofin’s business may not meet future expectations
due to these factors despite our integration efforts.

Our future results will suffer if we do not effectively  manage our  expanded operations  following the merger.

Following the merger, the size of the business of the combined company has increased

significantly. Our future success depends, in part, upon our ability  to  manage  this expanded business,
which  will pose substantial challenges for management, including challenges  related to the  management
and monitoring of new operations and  associated increased  costs and complexity. There  can be no

22

assurances that we will be successful or  that we  will  realize the expected synergies  and benefits
anticipated from the merger.

We have  incurred and will continue to  incur substantial expenses  related to the merger  with and the
integration of Rofin.

We  have and expect to continue to incur substantial expenses in connection with the  merger  and

the integration of Rofin. There are a  large number of processes,  policies,  procedures,  operations,
technologies and systems that will need to be integrated,  including purchasing, accounting and finance,
sales, payroll, pricing, marketing and employee benefits. While we have assumed  that  a certain level  of
expenses will be incurred, there are many  factors beyond  our  control  that could affect  the total amount
or the timing of the integration expenses.  Moreover, many of the  expenses that will be incurred are, by
their nature, difficult to estimate accurately. These expenses  could, particularly in the  near term, exceed
the savings we expect to achieve from the  elimination of duplicative expenses and the realization of
economies of scale and cost savings. These integration expenses could result  in significant  charges to
earnings which we cannot currently quantify.

Charges to earnings resulting from the  application of the purchase method of  accounting  to the Rofin
acquisition may adversely affect our results  of operations.

In accordance with generally accepted  accounting principles, we will account for  the Rofin

acquisition using the purchase method of accounting, which  will result in charges to earnings that could
have a material adverse effect on the  market  value of our  common  stock following  completion  of the
acquisition. Under the purchase method  of accounting, we will allocate the total purchase price  of
Rofin’s net tangible and identifiable intangible assets based upon their estimated fair  values  at the
acquisition date. The excess of the purchase price over net tangible and identifiable intangible assets
will be recorded as goodwill. We will incur additional depreciation and amortization expense over  the
useful lives of certain of the net tangible  and intangible assets  acquired in connection with the
acquisition. In addition, to the extent  the value of goodwill or  intangible assets with indefinite  lives
becomes impaired, we may be required  to  incur  material charges  relating  to  the impairment of those
assets. These depreciation, amortization and  potential impairment charges could have a  material  impact
on our results of operations.

Our indebtedness following the merger is substantially  greater  than our  indebtedness  prior to the  merger.  This
increased level of indebtedness could adversely affect us, including by decreasing our business  flexibility, and
will increase our borrowing costs.

In November 2016 we entered into the Credit  Agreement which provides for a 670  million  Euro

term loan, all of which has been drawn, and a  $100 million revolving  credit facility, under which a
10 million Euro letter of credit has been issued. We may incur additional indebtedness in the future  by
accessing the revolving credit facility under the Credit Agreement and/or entering into new financing
arrangements. Our ability to pay interest  and repay the  principal  of  our current indebtedness is
dependent upon our ability to manage our business operations and the ongoing interest rate
environment. There can be no assurance  that  we will be able to manage  any of these risks successfully.

The Credit Agreement contains customary affirmative covenants, including covenants regarding the

payment of taxes and other obligations,  maintenance  of  insurance, reporting requirements  and
compliance with applicable laws and regulations, and  negative covenants,  including covenants  limiting
the ability of us and our subsidiaries to, among other things, incur debt, grant liens, make investments,
make certain restricted payments, transact with  affiliates,  and sell assets.  The  Credit  Agreement also
requires us and our subsidiaries to maintain a senior secured  net leverage  ratio as  of  the last  day of
each  fiscal quarter of less of than or equal  to  3.50 to 1.00. The  Credit Agreement contains customary
events of default that include, among other things, payment defaults,  cross defaults with  certain other

23

indebtedness, violation of covenants, inaccuracy  of  representations and  warranties  in any  material
respect, change in  control of the Company  and  the Borrower, judgment  defaults, and bankruptcy and
insolvency events. If an event of default exists, the lenders may require  the  immediate payment of  all
Obligations, as defined in the Credit Agreement, and  may exercise certain other rights and  remedies
provided for under the Credit Agreement, the  other loan documents and applicable law. The
acceleration of such obligations is automatic upon  the occurrence  of a bankruptcy and insolvency event
of default. There can be no assurance  that we  will  have sufficient financial  resources  or we  will be able
to arrange financing to repay our borrowings at such time.

Our substantially increased indebtedness  and higher debt-to-equity ratio following completion of

the merger in comparison to that prior to the merger will have  the effect, among other things, of
reducing our flexibility to respond to  changing business and economic conditions and will  increase our
borrowing costs. In addition, the amount  of  cash  required to service  our increased indebtedness levels
and thus the demands on our cash resources will be greater than the amount of cash flows required  to
service our indebtedness or that of Rofin  individually  prior to the merger.  The  increased  levels of
indebtedness  could also reduce funds  available for our investments  in product development as well  as
capital expenditures, dividends, share  repurchases and other activities and  may create  competitive
disadvantages for us relative to other  companies with lower  debt levels.

We may  not be able to divest the Rofin  business located in Hull, England  on favorable terms.

On October 26, 2016, the European Commission approved  under the  EU Merger  Regulation our
acquisition of Rofin, conditional on the divestment of Rofin’s  low  power CO2 laser business based in
Hull, United Kingdom (the ‘‘Hull Business’’) after the closing of the acquisition. We are  required to
hold the Hull Business separate until  such  time as it is divested.  During  fiscal  years  2013 through 2015,
the Hull Business had annual revenues  of approximately 23-25  million  British Pound Sterling and,
accordingly, we will not have the revenue from the  Hull Business  once it is sold.  If we  are unable to
successfully timely divest the Hull Business or  if the  European Commission does not approve a
proposed sale thereof, then a divestiture trustee may  be  appointed by  the European  Commission and
the terms for any sale of the Hull Business will be at the discretion of such trustee. During the period
of time in which we are holding the Hull Business separate, the conditions for such structure may be a
distraction on certain members of our senior management team.

BUSINESS ENVIRONMENT AND INDUSTRY TRENDS

Our operating results, including net sales,  net income (loss)  and  adjusted  EBITDA in dollars  and as a
percentage of net sales, as well as our stock  price  have varied in the past, and our future operating  results,
including those results from the newly acquired Rofin business,  will  continue to be subject  to quarterly  and
annual fluctuations based upon numerous  factors, including  those discussed in this Item 1A and throughout
this report. Our stock price will continue to be subject to daily variations as well. Our future operating  results
and stock price may not follow any past trends or meet our guidance and expectations.

Our net  sales and  operating results, such as  adjusted EBITDA percentage, net  income  (loss)  and

operating expenses, and our stock price have varied  in the  past  and may vary  significantly  from quarter
to quarter and from year to year in the future.  We believe a number of factors, many of which are
outside of our control, could cause these variations and make them difficult to predict, including:

(cid:127) general economic uncertainties in the macroeconomic  and local economies facing us,  our

customers and the markets we serve;

(cid:127) fluctuations in demand for our products or downturns in  the industries that we  serve;

24

(cid:127) the ability of our suppliers, both internal and external, to  produce and  deliver  components and
parts, including sole or limited source  components, in a timely  manner,  in the quantity, quality
and prices desired;

(cid:127) the timing of receipt and conversion  of  bookings  to  net sales;

(cid:127) the concentration of a significant amount of our backlog,  and  resultant net sales, with a few

customers;

(cid:127) rescheduling of shipments or cancellation of orders by our  customers;

(cid:127) fluctuations in our product mix;

(cid:127) the ability of our customers’ other  suppliers to provide  sufficient material to support our

customers’ products;

(cid:127) currency fluctuations and stability, in particular the Euro, the  Japanese Yen,  the South Korean

Won, the Chinese RMB and the US dollar  as compared to other currencies;

(cid:127) commodity pricing;

(cid:127) introductions of new products and product  enhancements by  our competitors, entry of new

competitors into our markets, pricing pressures and other competitive factors;

(cid:127) our ability to develop, introduce, manufacture  and  ship new and  enhanced products in a  timely

manner without defects;

(cid:127) our ability to successfully expand our manufacturing capacity  in G¨ottingen, Germany and add

optics fabrication capacity at our site in Richmond, California;

(cid:127) our ability to manage our manufacturing capacity and that of our suppliers;

(cid:127) our reliance on contract manufacturing;

(cid:127) the rate of market acceptance of our new products;

(cid:127) the ability of our customers to pay  for our products;

(cid:127) expenses associated with acquisition-related activities;

(cid:127) seasonal sales trends;

(cid:127) access  to applicable credit markets by  us, our  customers and their end  customers;

(cid:127) delays or reductions in customer purchases of our  products  in anticipation of the introduction of

new and enhanced products by us or our competitors;

(cid:127) our ability to control expenses;

(cid:127) the level of capital spending of our  customers;

(cid:127) potential excess and/or obsolescence of our  inventory;

(cid:127) costs and timing of adhering to current and developing governmental regulations and reviews

relating to our products and business;

(cid:127) costs related to acquisitions of technology or businesses;

(cid:127) impairment of goodwill, intangible  assets and other  long-lived assets;

(cid:127) our ability to meet our expectations and forecasts and those of public market analysts  and

investors;

25

(cid:127) the availability of research funding by  governments with regard  to  our customers in the scientific

business, such as universities;

(cid:127) continued government spending on  defense-related projects where we  are a subcontractor;

(cid:127) maintenance of supply relating to products sold to the government on  terms which  we would

prefer not to accept;

(cid:127) changes in policy, interpretations, or challenges to the allowability of costs  incurred under

government cost accounting standards;

(cid:127) damage to our reputation as a result of coverage in  social  media, Internet  blogs or  other  media

outlets;

(cid:127) managing our and other parties’ compliance with contracts in multiple  languages and

jurisdictions;

(cid:127) managing our internal and third party sales  representatives and distributors, including

compliance with all applicable laws;

(cid:127) impact of government economic policies on macroeconomic conditions;

(cid:127) costs and expenses from litigation;

(cid:127) costs associated with designing around or payment  of licensing fees associated  with issued

patents in our fields of business;

(cid:127) government support of alternative energy industries,  such as solar;

(cid:127) negative impacts related to the recent  ‘‘Brexit’’ vote  by the United Kingdom, particularly with
regard to sales from our Glasgow, Scotland  facility  to  other  jurisdictions and purchases of
supplies from outside the United Kingdom  by  such facility;

(cid:127) the future impact of legislation, rulemaking, and changes  in accounting, tax, defense

procurement, or export policies; and

(cid:127) distraction of management related to acquisition or divestment activities.

In addition, we often recognize a substantial portion of our sales in the  last month of our fiscal

quarters. Our expenses for any given quarter are typically based on expected sales and  if sales are
below expectations in any given quarter, the adverse impact of the shortfall on our operating results
may be magnified by our inability to  adjust spending quickly enough to compensate for the shortfall.
We  also base our manufacturing on our  forecasted product mix  for the  quarter.  If the actual  product
mix varies significantly from our forecast,  we may not be able to fill  some orders during that quarter,
which  would result in delays in the shipment of our products. Accordingly, variations in timing  of  sales,
particularly for our higher priced, higher  margin products, can cause  significant fluctuations  in quarterly
operating results.

Due to these and other factors, such as varying product mix, we believe that quarter-to-quarter and
year-to-year comparisons of our historical operating results may  not  be  meaningful. You should  not  rely
on our results for any quarter or year as  an  indication of  our future performance. Our  operating results
in future quarters and years may be below public market analysts’  or investors’ expectations, which
would likely cause the price of our stock  to  fall. In addition, over the  past several years, U.S. and
global  equity markets have experienced significant price and volume fluctuations that have affected the
stock prices of many technology companies  both in and outside our  industry.  There has not always
been a direct correlation between this volatility  and the  performance of particular  companies subject to
these stock price fluctuations. These factors, as well  as general economic  and political conditions or

26

investors’ concerns regarding the credibility of  corporate financial statements,  may have a material
adverse effect on the market price of our stock in the future.

We depend on sole source or limited source suppliers,  both internal  and external, for some of our key
components and materials, including exotic materials, certain cutting-edge  optics and  crystals,  in our products,
which make us susceptible to supply shortages or price fluctuations that could adversely affect  our business,
particularly our ability to meet our customers’ delivery requirements.

We  currently purchase several key components  and materials used in the manufacture of our
products from sole source or limited  source suppliers, both internal  and external. In  particular, from
time-to-time our customers require us to ramp  up production and/or  accelerate delivery schedules of
our  products. Our key suppliers may not have  the ability to increase their production in  line with our
customers’ demands. This can become  acute during times of high growth in our customers’ businesses.
Our failure to timely receive these key  components and materials would  likely cause delays in the
shipment of our products, which would  likely  negatively impact both our customers and our  business.
Some of these suppliers are relatively small private  companies that may discontinue  their operations at
any time and which may be particularly  susceptible  to  prevailing economic  conditions. Some of our
suppliers are located in regions which  may be susceptible  to  natural disasters, such  as the flooding in
Thailand and the earthquake, tsunami and resulting nuclear  disaster in Japan and severe flooding and
power loss in the Eastern part of the United States in recent years. Some may  be  vulnerable to
man-made disasters, such as the recent  worldwide shortage of neon gas as  a result of the  conflict in
Ukraine. We typically purchase our components and materials through  purchase  orders  or agreed upon
terms and conditions and we do not  have  guaranteed supply  arrangements  with many of these
suppliers. For certain long-lead time supplies or  in order to  lock-in pricing, we  may be obligated to
place purchase orders which are not  cancelable or otherwise assume liability for a large amount of the
ordered supplies, which limit our ability  to  adjust down our inventory  liability  in the event of  market
downturns or other customer cancellations or rescheduling of their purchase  orders  for our products.
Some of our products, particularly in the  flat panel display industry,  require designs and specifications
which  are at the cutting-edge of available technologies. Our and  our customers’ designs and
specifications frequently change to meet rapidly  evolving  market  demands. Accordingly, certain of  our
products require components and supplies which  may  be  technologically difficult and unpredictable to
manufacture. By their very nature, these types of components may only be available by a single
supplier. These characteristics further  pressure the timely delivery of such components.  We may fail  to
obtain these supplies in a timely manner  in the future. We  may experience difficulty  identifying
alternative sources of supply for certain components used in our products and may have  to  incur
expenses and management distraction in assisting  our current and future  suppliers to meet our and our
customers’ technical requirements. We would experience further delays while identifying,  evaluating  and
testing the products of these potential alternative suppliers.  Furthermore,  financial or  other difficulties
faced by these suppliers or significant  changes in  demand  for these components  or materials could limit
their availability. We continue to consolidate  our supply base  and move supplier locations. When we
transition locations we may increase  our inventory of such  products as  a  ‘‘safety stock’’ during the
transition, which may cause the amount of inventory reflected on our balance sheet to increase.
Additionally, many of our customers  rely  on sole source  suppliers. In  the event of a  disruption of our
customers’ supply chain, orders from our  customers  could decrease or be delayed.

Any interruption or delay in the supply of any of these components or materials, or  the inability to

obtain these components and materials  from alternate sources  at acceptable prices  and within a
reasonable amount of time, or our failure  to  properly manage these moves,  would impair our ability to
meet scheduled product deliveries to our  customers and could  cause customers to cancel  orders.  We
have historically relied exclusively on  our  own production capability  to  manufacture certain strategic
components, crystals, semiconductor lasers, lasers and laser-based  systems and recently acquired the
capability to manufacture certain large format optics. Because we  manufacture, package and test these

27

components, products and systems at our own facilities, and such components, products and  systems
are not readily available from other sources, any interruption in manufacturing would  adversely affect
our  business. Since many of our products have  lengthy qualification  periods, our ability to introduce
multiple suppliers for parts may be limited. In addition, our  failure to achieve  adequate manufacturing
yields of these items at our manufacturing facilities may materially and  adversely affect our operating
results and financial condition.

We participate in the microelectronics market, which  requires  significant  research and  development  expenses to
develop and maintain products and a failure  to  achieve market  acceptance for  our products  could have a
significant negative impact on our business  and  results of operations.

The microelectronics market is characterized by rapid technological  change,  frequent product

introductions, the volatility of product  supply and  demand,  changing  customer requirements and
evolving industry standards. The nature of this market requires significant research and  development
expenses to participate, with substantial  resources invested in advance  of material sales  of our  products
to our customers in this market. Additionally,  our product offerings may become obsolete given the
frequent introduction of alternative technologies. In the event either  our customers’  or our products  fail
to gain market acceptance, or the microelectronics market fails  to  grow, it  would likely  have a
significant negative effect on our business and results  of operations.

We participate in the flat panel display  market, which has  a relatively limited number of end customer
manufacturers. Our backlog, timing of net  sales and results  of  operations could be  negatively impacted in the
event our customers reschedule or cancel  orders.

In the flat panel display market, there are  a relatively limited number  of manufacturers who are
the end customers for our annealing  products. In fiscal 2016, Advanced Process Systems Corporation,
an integrator in the flat panel display market based in South  Korea, and Japanese Steel  Works, Ltd., an
integrator in the flat panel display market based  in Japan, contributed more  than 10%  of our  revenue.
Given macroeconomic conditions, varying consumer demand and technical process  limitations at
manufacturers, our customers may seek to reschedule or cancel  orders.  This was  recently  seen with  a
requested expedited shipment of a Linebeam 1500 product  for our  third  fiscal  quarter  of 2015, which
delivery date was then changed at the  customer’s request  back to its originally scheduled  date in  the
fourth fiscal quarter of 2015. These larger  flat panel-related systems have large average  selling prices.
Any rescheduling or canceling of such  orders  by  our customers will likely have a significant impact on
our  quarterly or annual net sales and results of operations and could negatively  impact  inventory values
and backlog. Additionally, challenges  in meeting evolving technological requirements for these complex
products by us and our suppliers could also result in  delays in  shipments, rescheduled or  canceled
orders by our customers. This could  negatively impact  our backlog, timing of net  sales  and results of
operations.

As of October 1, 2016, flat panel display  systems represented 63% of our  backlog, compared
to 32% at October 3, 2015. Since our backlog  includes higher  average  selling  price flat panel display
systems, any delays or cancellation of shipments could have a material  adverse effect on  our  financial
results.

Some of our laser systems are complex  in  design and may contain  defects that are  not  detected until deployed
by  our customers, which could increase  our costs and reduce our net  sales.

Lasers  and laser systems are inherently  complex in  design and require ongoing regular

maintenance. The manufacture of our lasers, laser products and systems  involves  a highly  complex and
precise process. As a result of the technological  complexity  of  our products,  in particular the flat panel
annealing systems, changes in our or  our  suppliers’  manufacturing processes or the  inadvertent use of
defective materials by us or our suppliers could result in a material adverse  effect on our ability to

28

achieve acceptable manufacturing yields  and product  reliability. To the extent that we do not achieve
and maintain our projected yields or product reliability, our business, operating results, financial
condition and customer relationships would be adversely affected. We  provide warranties on  a majority
of our product sales, and reserves for  estimated  warranty costs are recorded during the  period of  sale.
The determination of such reserves requires us to make estimates of failure rates and  expected costs to
repair or replace the products under  warranty. We  typically  establish warranty reserves based  on
historical warranty costs for each product  line. If actual  return rates and/or  repair and replacement
costs differ significantly from our estimates, adjustments  to cost of sales may be required in future
periods which could have an adverse effect on  our  results of operations.

Our customers may discover defects in our products after the  products have been fully  deployed

and operated, including under the end user’s peak stress conditions. In addition, some of our products
are combined with products from other  vendors, which may contain  defects. As a  result, should
problems occur, it may be difficult to  identify the source of the  problem. If  we are  unable to identify
and fix defects or other problems, we could  experience,  among  other things:

(cid:127) loss of customers or orders;

(cid:127) increased costs of product returns  and warranty expenses;

(cid:127) damage to our brand reputation;

(cid:127) failure to attract new customers or achieve market acceptance;

(cid:127) diversion of development, engineering  and  manufacturing  resources; and

(cid:127) legal actions by our customers and/or their end users.

The occurrence of any one or more of  the foregoing factors could seriously harm our business,

financial condition and results of operations.

Continued volatility in the advanced packaging and semiconductor  manufacturing markets could adversely
affect our business, financial condition  and  results of operations.

A portion of our net sales in the microelectronics  market  depends  on the demand  for our products

by advanced packaging applications and semiconductor equipment  companies. These markets have
historically been characterized by sudden  and severe  cyclical variations  in product supply and  demand,
which  have often severely affected the  demand for semiconductor manufacturing equipment, including
laser-based tools and systems. The timing,  severity and duration  of  these market  cycles are difficult to
predict, and we may not be able to respond effectively  to  these cycles. The continuing uncertainty in
these markets severely limits our ability  to predict our business prospects or financial results  in these
markets.

During  industry downturns, our net sales  from these markets  may  decline suddenly and
significantly. Our ability to rapidly and  effectively reduce our  cost structure  in response to such
downturns is limited by the fixed nature of many of our expenses  in the near  term and by our  need  to
continue our investment in next-generation product  technology and to support and service our
products. In addition, due to the relatively long manufacturing lead times for  some of the  systems and
subsystems we sell to these markets, we may incur expenditures or purchase raw  materials or
components for products we cannot sell. Accordingly, downturns in the semiconductor capital
equipment market may materially harm our operating results. Conversely, when upturns  in these
markets occur, we must be able to rapidly  and effectively increase our  manufacturing capacity  to  meet
increases in customer demand that may  be  extremely  rapid, and if we  fail  to  do  so we may lose
business to our competitors and our relationships with  our customers  may  be  harmed.

29

We are exposed to risks associated with  worldwide economic conditions and related uncertainties which could
negatively impact demand for our products  and results  of  operations.

Volatility and disruption in the capital and credit markets, depressed consumer confidence,
government economic policies, negative  economic  conditions, volatile corporate  profits and reduced
capital spending could negatively impact demand  for our products. In particular, it  is difficult to
develop and implement strategy, sustainable business models and efficient operations,  as well as
effectively manage supply chain relationships in the  face of such conditions including uncertainty
regarding the ability of some of our suppliers to continue operations  and  provide us with uninterrupted
supply flow. Our ability to maintain our research and development investments in  our  broad product
offerings may be adversely impacted  in the  event that our sales  decline and do not increase in  the
future. Spending and the timing thereof  by consumers  and  businesses have a significant impact on  our
results and, where such spending is delayed or  canceled, it could  have a material negative impact on
our  operating results. Current global  economic conditions remain  uncertain and challenging. Weakness
in our end markets could negatively impact our  net sales, gross margin and  operating expenses, and
consequently have a material adverse  effect on  our  business, financial condition  and results of
operations.

Uncertainty in global fiscal policy has  likely had an  adverse impact  on global  financial markets and

overall economic activity in recent years.  Should this uncertain financial policy recur, it  would likely
negatively impact global economic activity.  Any  weakness in global economies would  also likely have
negative repercussions on U.S. and global credit and financial markets, and  further exacerbate
sovereign debt concerns in the European Union. All  of  these factors would  likely adversely impact the
global  demand for our products and  the  performance of  our investments, and  would likely  have a
material adverse effect on our business, results of operations and  financial condition.

The financial turmoil that has affected  the banking system and financial markets in  recent years

could result in tighter credit markets  and lower levels of liquidity  in some financial markets. There
could be a number of follow-on effects from a  tightened credit environment on our business, including
the insolvency of key suppliers or their  inability to obtain credit to finance development and/or
manufacture products resulting in product delays; inability of customers to obtain credit to finance
purchases of our products and/or customer  insolvencies; and failure of  financial institutions negatively
impacting our treasury functions. In the  event  our  customers are unable to obtain credit or otherwise
pay for our shipped products it could significantly impact our ability  to  collect on our outstanding
accounts receivable. Other income and expense also could vary materially  from expectations depending
on gains or losses realized on the sale or  exchange of financial instruments;  impairment charges
resulting from revaluations of debt and equity securities and other investments; interest rates; cash
balances; and changes in fair value of  derivative instruments. Volatility  in the financial markets and any
overall economic uncertainty increase the  risk  that the actual amounts realized in the future  on our
financial instruments could differ significantly from  the fair values currently assigned to them.
Uncertainty about current global economic conditions could also  continue to increase the  volatility  of
our  stock price.

In addition, political and social turmoil related to international  conflicts,  terrorist  acts,  civil unrest
and mass migration may put further  pressure on economic  conditions in the United States and the rest
of the world. Unstable economic, political and social  conditions make  it difficult  for our customers, our
suppliers and us to accurately forecast and plan  future business activities. If such  conditions persist,  our
business, financial condition and results  of operations could suffer. Additionally, unstable  economic
conditions can provide significant pressures and burdens on individuals, which could cause  them to
engage in inappropriate business conduct. See ‘‘Part II,  Item 9A. CONTROLS AND PROCEDURES.’’

30

Our cash and cash equivalents and short-term investments are managed through various banks around the
world and volatility in the capital and credit market conditions could cause financial institutions to fail or
materially harm service levels provided by  such banks, both  of  which  could  have  an  adverse impact  on our
ability to timely access funds.

World capital and credit markets have  been and may continue to experience volatility and
disruption. In some cases, the markets  have  exerted downward pressure  on  stock  prices and credit
capacity  for certain issuers, as well as  pressured the solvency of some financial institutions. These
financial institutions, including banks,  have  had difficulty timely performing regular  services  and in
some cases have failed or otherwise been  largely  taken  over by governments. We maintain our cash,
cash equivalents and short-term investments  with a number of financial institutions around  the world.
Should some or all of these financial institutions fail or otherwise be unable to timely  perform
requested services, we would likely have a  limited ability to  timely  access our cash  deposited with such
institutions, or, in extreme circumstances the failure of such institutions  could cause us to be unable to
access cash for the foreseeable future. If  we are unable to quickly access  our  funds when we need
them, we may need to increase the use of our  existing credit lines or access  more expensive credit, if
available. If we are unable to access  our  cash or if we access  existing or  additional credit or are unable
to access additional credit, it could have a  negative  impact on our operations, including our  reported
net income. In addition, the willingness  of  financial institutions to continue to accept our cash deposits
will impact our ability to diversify our  investment risk among institutions.

We are exposed to credit risk and fluctuations in the  market values of our investment portfolio.

Although we have not recognized any material losses on our cash,  cash equivalents and short-term
investments, future declines in their market values could have  a  material adverse effect on our  financial
condition and operating results. Given the  global nature  of our  business,  we have investments both
domestically and internationally. There has  recently been growing  pressure on the creditworthiness of
sovereign nations, particularly in Europe  where  a significant  portion of our cash,  cash equivalents and
short-term investments are invested, which results in corresponding  pressure on the valuation of the
securities issued by such nations. Additionally, our  overall investment portfolio is  often  concentrated  in
government-issued securities such as U.S.  Treasury securities and government agencies, corporate notes,
commercial paper and money market  funds. Credit ratings and pricing of these investments  can be
negatively impacted by liquidity, credit deterioration or  losses,  financial  results,  or other factors.
Additionally, liquidity issues or political  actions by sovereign nations could result  in decreased values
for our  investments in certain government securities. As a  result, the  value or  liquidity of our cash,  cash
equivalents and short-term investments  could decline or become materially impaired, which could have
a material adverse effect on our financial  condition and operating  results. See ‘‘Item 7A.  Quantitative
and Qualitative Disclosures about Market Risk.’’

Our future success depends on our ability to increase our  sales  volumes and decrease our  costs to  offset
potential declines in the average selling  prices (‘‘ASPs’’) of our products and,  if we are  unable to realize
greater sales volumes and lower costs, our  operating results  may  suffer.

Our ability to increase our sales volume and our future success depends on  the continued growth

of the markets for  lasers, laser systems and related accessories, as  well as our ability to identify, in
advance, emerging markets for laser-based systems.  We cannot  assure you  that  we will be able to
successfully identify, on a timely basis, new  high-growth markets  in the  future. Moreover, we cannot
assure you that new markets will develop  for our products  or our customers’  products, or  that  our
technology or pricing will enable such  markets to develop. Future demand for  our  products is uncertain
and will depend to a great degree on continued  technological development and the introduction of new
or enhanced products. If this does not continue, sales of our  products may decline and our business will
be harmed.

31

We  have in the past experienced decreases in  the ASPs of some of our products. As  competing
products become more widely available,  the ASPs of  our products may decrease.  If we  are unable to
offset any decrease in our ASPs by increasing  our  sales volumes, our net sales will decline. In addition,
to maintain our gross margins, we must continue to reduce the  cost of manufacturing our products
while maintaining their high quality.  From  time to time, our products, like many complex technological
products, may fail in greater frequency than anticipated. This can  lead to further charges, which can
result in higher costs, lower gross margins and lower operating results. Furthermore,  as ASPs of our
current products decline, we must develop  and introduce new products and product  enhancements with
higher  margins. If we cannot maintain our gross  margins, our operating results could be seriously
harmed, particularly if the ASPs of our  products decrease  significantly.

Our future success depends on our ability to develop and successfully introduce  new and enhanced products
that meet the needs of our customers.

Our current products address a broad range  of commercial and  scientific research  applications  in

the photonics markets. We cannot assure you that the  market  for  these  applications  will continue to
generate significant or consistent demand  for our products.  Demand for our  products could be
significantly diminished by disrupting  technologies or products  that replace them or render them
obsolete. Furthermore, the new and enhanced products  in certain markets generally continue to be
smaller in size and have lower ASPs,  and  therefore,  we have  to  sell more units to maintain revenue
levels. Accordingly, we must continue to invest in research and development in order  to  develop
competitive products.

Our future success depends on our ability to anticipate our  customers’ needs and develop products
that address those needs. Introduction  of new products  and product enhancements will require that we
effectively transfer production processes  from research and  development to manufacturing and
coordinate our efforts with those of our suppliers  to  achieve volume production rapidly.  If we  fail to
transfer production processes effectively,  develop product enhancements  or  introduce new products  in
sufficient quantities to meet the needs of  our customers  as scheduled, our net sales may  be  reduced
and our business may be harmed.

We face risks associated with our foreign  operations and sales that  could harm our financial condition  and
results of operations.

For fiscal 2016, fiscal 2015 and fiscal  2014, 76%, 73%  and 74%, respectively,  of  our  net sales  were

derived from customers outside of the  United States. A  majority of Rofin’s sales have also been to
customers outside of the United States in  recent  years.  We anticipate  that  foreign sales,  particularly in
Asia, will continue to account for a significant portion of  our net  sales in the foreseeable future.

A global economic slowdown or a natural  disaster could have a negative effect on  various foreign
markets in which we operate, such as  the  earthquake, tsunami and resulting nuclear  disaster in Japan
and the flooding in Thailand in recent years. Such a slowdown may cause us to reduce  our  presence in
certain countries, which may negatively  affect the  overall level of business in  such countries. Our
foreign sales are primarily through our  direct sales force. Additionally,  some foreign  sales are made
through foreign distributors and representatives.  Our  foreign operations  and  sales  are subject to a
number of risks, including:

(cid:127) longer accounts receivable collection periods;

(cid:127) the impact of recessions and other  economic conditions in economies outside the United  States;

(cid:127) unexpected changes in regulatory requirements;

(cid:127) certification requirements;

32

(cid:127) environmental regulations;

(cid:127) reduced protection for intellectual property rights  in some  countries;

(cid:127) potentially adverse tax consequences;

(cid:127) political and economic instability;

(cid:127) import/export regulations, tariffs and trade  barriers;

(cid:127) compliance with applicable United States and foreign anti-corruption  laws;

(cid:127) cultural and management differences;

(cid:127) reliance in some jurisdictions on third party sales channel partners;

(cid:127) preference for locally produced products;  and

(cid:127) shipping and other logistics complications.

Our business could also be impacted  by international conflicts, terrorist and military activity, civil
unrest and pandemic illness which could cause a slowdown in customer orders, cause customer order
cancellations or negatively impact availability of supplies or  limit our  ability to timely service our
installed base of products.

We  are also subject to the risks of fluctuating foreign currency  exchange rates, which  could
materially adversely affect the sales price  of  our products in  foreign markets, as  well as the  costs and
expenses of our foreign subsidiaries. While  we use forward  exchange  contracts and other risk
management techniques to hedge our foreign currency exposure, we remain exposed to the  economic
risks of foreign currency fluctuations.

We may  not be able to protect our proprietary technology which could adversely affect our competitive
advantage.

Maintenance of intellectual property rights and the protection thereof is important  to  our business.

We  rely  on a combination of patent, copyright, trademark  and trade secret laws and restrictions on
disclosure to protect our intellectual property rights. Our patent applications  may not be approved, any
patents that may be issued may not sufficiently protect our  intellectual property and any issued patents
may be challenged by third parties. Other parties may independently  develop similar  or competing
technology or design around any patents that may be issued to us.  We cannot  be  certain  that  the steps
we have taken will prevent the misappropriation  of  our  intellectual  property,  particularly in foreign
countries where the laws may not protect  our  proprietary  rights as  fully as  in the United States.
Further, we may be required to enforce  our intellectual property or other proprietary  rights through
litigation, which, regardless of success,  could result  in substantial  costs  and diversion of management’s
attention. Additionally, there may be  existing patents of which we are unaware that could be pertinent
to our business and it is not possible for  us to know  whether there are patent  applications pending  that
our  products might infringe upon since these applications  are often not publicly  available until  a patent
is issued or published.

We may, in the future, be subject to claims  or  litigation  from third parties, for  claims  of infringement  of their
proprietary rights or to determine the scope  and validity of our proprietary rights or the  proprietary rights of
competitors or other rights holders. These  claims could  result in costly litigation and the  diversion of our
technical and management personnel. Adverse resolution of litigation may harm our operating results or
financial condition.

In recent years, there has been significant  litigation in the United States and around the world
involving patents and other intellectual  property rights.  This has been seen in our industry, for example

33

in the recently concluded patent-related litigation between IMRA America,  Inc. (‘‘Imra’’) and IPG
Photonics Corporation and in Imra’s recently brought  litigation against two of  our German subsidiaries.
From time to time, like many other technology companies, we have  received  communications from
other parties asserting the existence of patent  rights, copyrights, trademark rights  or other intellectual
property rights which such third parties  believe may cover certain of our  products, processes,
technologies or information. In the future,  we may be a  party to litigation to protect  our intellectual
property or as a result of an alleged infringement of others’ intellectual property whether through
direct claims or by way of indemnification claims of our customers,  as, in  some cases, we contractually
agree to  indemnify our customers against  third-party  infringement claims  relating  to  our  products.
These claims and any resulting lawsuit,  if successful, could subject us to significant liability for  damages
or invalidation of our proprietary rights. These lawsuits, regardless of their success, would likely be
time-consuming and expensive to resolve and would  divert  management time and  attention. Any
potential intellectual property litigation could  also force us to do one or more of the following:

(cid:127) stop manufacturing, selling or using our products  that use the  infringed intellectual property;

(cid:127) obtain from the owner of the infringed intellectual property right  a  license  to  sell or  use the

relevant technology, although such license  may  not  be  available on reasonable  terms, or at all; or

(cid:127) redesign the products that use the technology.

If we  are forced to take any of these  actions or are otherwise a party  to  lawsuits  of this  nature, we

may incur significant losses and our business  may  be  seriously harmed. We do not have insurance to
cover potential claims of this type.

If our goodwill or intangible assets become  impaired, we may be required to record a significant  charge to
earnings.

Under accounting principles generally  accepted in the  United States, we review our intangible
assets for impairment when events or  changes in circumstances indicate  the carrying value may not be
recoverable. Goodwill is required to  be  tested for  impairment  at  least annually.  Factors that may  be
considered in determining whether a  change in circumstances indicating that the carrying value  of  our
goodwill or other intangible assets may not be recoverable include  declines  in our stock price and
market capitalization or future cash flows projections. A decline  in our stock price, or  any other
adverse change in market conditions,  particularly if such  change has the effect  of  changing one of  the
critical assumptions or estimates we used  to calculate the  estimated  fair value of our reporting units,
could result in a change to the estimation  of fair value that  could result in an impairment  charge. Any
such material charges, whether related to goodwill or purchased intangible assets, may  have a material
negative impact on our financial and operating results.

We depend on skilled personnel to operate our  business effectively in a rapidly changing market, and if we are
unable to retain existing or hire additional personnel when  needed, our ability to  develop and sell our products
could be harmed.

Our ability to continue to attract and  retain highly skilled  personnel will  be a  critical factor in

determining whether we will be successful in  the future.  Recruiting  and retaining highly skilled
personnel in certain functions continues  to  be  difficult.  At certain locations where we operate, the  cost
of living is extremely high and it may  be  difficult to retain key employees  and management at  a
reasonable cost. We may not be successful  in attracting,  assimilating or retaining qualified personnel to
fulfill our current or future needs. Our  failure to attract  additional employees and  retain our existing
employees could adversely affect our growth and our business.

Our future success depends upon the continued services of  our executive officers  and other  key
engineering, sales, marketing, manufacturing and  support personnel,  any of  whom  may leave and our

34

ability to effectively transition to their  successors. Our  inability to retain or to effectively  transition  to
their successors could harm our business and our results of operations.

The long sales cycles for our products may cause us to incur significant expenses without  offsetting net  sales.

Customers often view the purchase of our products as a significant and strategic  decision. As a
result, customers typically expend significant effort  in evaluating, testing and  qualifying our products
before making a decision to purchase them, resulting  in a lengthy initial sales cycle. While our
customers are evaluating our products  and before they place an order  with us,  we may incur substantial
sales and marketing and research and development expenses  to  customize our products to the
customers’ needs. We may also expend significant management efforts,  increase manufacturing capacity
and order long lead-time components  or  materials  prior to receiving an  order. Even after this
evaluation process, a potential customer  may not purchase our products. As  a result, these long  sales
cycles may cause us to incur significant  expenses without ever receiving net sales to offset  such
expenses.

The markets in which we sell our products are  intensely competitive and  increased competition  could cause
reduced sales levels, reduced gross margins  or the loss  of market  share.

Competition in the various photonics  markets  in which we provide products is very intense. We

compete against a number of large public  and private  companies, including CVI  Melles Griot,
Novanta Inc., IPG Photonics Corporation, Lumentum  Holdings Inc., MKS  Instruments,  Inc. and
Trumpf GmbH, as well as other smaller  companies. Some of our competitors are  large companies that
have significant financial, technical, marketing  and  other  resources.  These  competitors may be able to
devote greater resources than we can to the development, promotion,  sale and support of  their
products. Some of our competitors are  much better positioned than  we are  to  acquire other companies
in order to gain new technologies or  products that  may displace our  product lines. Any of these
acquisitions could give our competitors  a  strategic advantage.  Any  business combinations  or mergers
among our competitors, forming larger  companies with greater resources, could result in increased
competition, price reductions, reduced  margins  or loss  of market  share, any of which could materially
and adversely affect our business, results of operations and financial condition.

Additional competitors may enter the markets in which we serve, both  foreign and  domestic,  and

we are likely to compete with new companies  in the future. We may  encounter potential customers
that, due to existing relationships with our competitors,  are committed  to  the products  offered by these
competitors. Further, our current or potential  customers may determine to develop and produce
products for their own use which are  competitive to our products. As  a  result of  the foregoing factors,
we expect that competitive pressures  may  result in price reductions, reduced  margins, loss of sales and
loss of market share. In addition, in markets where there  are a  limited  number of customers,
competition is particularly intense.

If we fail to accurately forecast component and material requirements for  our products,  we could incur
additional costs and incur significant delays in shipments, which  could result in  a loss  of customers.

We  use rolling forecasts based on anticipated  product orders and material requirements planning

systems to determine our product requirements. It  is very  important that we accurately  predict both the
demand for our products and the lead times required to obtain the necessary components and
materials. We depend on our suppliers for most  of our product  components  and materials. Lead times
for components and materials that we order vary significantly and depend on factors including  the
specific  supplier requirements, the size  of  the order, contract terms and  current market demand for
components. For substantial increases  in  our sales levels  of  certain products, some  of  our  suppliers may
need at least nine months lead-time.  If we overestimate our  component  and material requirements, we
may have excess inventory, which would  increase our costs. If  we  underestimate our component and

35

material requirements, we may have inadequate inventory,  which could interrupt and delay  delivery of
our  products to our customers. Any of  these occurrences would  negatively impact our net sales,
business or operating results.

Our reliance on contract manufacturing  and outsourcing may adversely  impact our financial results and
operations due to our decreased control over the performance and timing of certain aspects of our
manufacturing.

Our manufacturing strategy includes  partnering with contract  manufacturers to outsource non-core

subassemblies and less complex turnkey products,  including  some performed at international sites
located in Asia and Eastern Europe.  Our  ability to resume  internal manufacturing operations for
certain products and components in a  timely manner may be eliminated. The cost,  quality, performance
and availability of contract manufacturing  operations  are and will  be  essential to the  successful
production and sale of many of our products. Our financial condition or results of  operation could be
adversely impacted if any contract manufacturer  or other supplier is  unable for  any reason, including as
a result of the impact of worldwide economic  conditions, to meet our cost,  quality, performance, and
availability standards. We may not be  able  to  provide contract  manufacturers  with product volumes  that
are high enough to achieve sufficient cost  savings. If shipments  fall below forecasted levels,  we may
incur increased costs or be required  to  take ownership of the  inventory. Also,  our  ability  to  control the
quality of products produced by contract manufacturers may be limited and quality issues  may not be
resolved  in a timely manner, which could  adversely  impact our financial condition or results  of
operations.

If we fail to effectively manage our growth or, alternatively, our spending during downturns, our business
could be disrupted, which could harm our operating  results.

Growth in sales, combined with the challenges  of  managing geographically dispersed operations,

can place a significant strain on our  management  systems and resources, and  our anticipated growth  in
future operations could continue to place such a strain.  The  failure to effectively manage our growth
could disrupt our business and harm our operating results. Our ability to  successfully  offer our products
and implement our business plan in evolving markets  requires  an effective planning and management
process. In economic downturns, we must  effectively manage our spending and  operations  to  ensure
our  competitive position during the downturn, as well as our future  opportunities when  the economy
improves, remain intact. The failure  to  effectively  manage our spending  and operations could disrupt
our  business and harm our operating  results.

Historically, acquisitions have been an important element  of  our  strategy. However,  we may not find suitable
acquisition candidates in the future and we  may not be able to successfully integrate  and manage acquired
businesses. Any acquisitions we make could disrupt our business and harm  our  financial condition.

We  have in the past made strategic acquisitions  of other corporations  and  entities, including  Rofin

in November 2016, as well as asset purchases,  and we continue to evaluate potential strategic
acquisitions of complementary companies, products and technologies. In the event of  any future
acquisitions, we could:

(cid:127) issue stock that would dilute our current  stockholders’ percentage  ownership;

(cid:127) pay cash that would decrease our working capital;

(cid:127) incur debt;

(cid:127) assume liabilities; or

(cid:127) incur expenses related to impairment of goodwill and amortization.

36

Acquisitions also involve numerous risks, including:

(cid:127) problems combining the acquired operations, systems, technologies or products;

(cid:127) an inability to realize expected operating efficiencies or product integration benefits;

(cid:127) difficulties in coordinating and integrating  geographically separated  personnel, organizations,

systems and facilities;

(cid:127) difficulties integrating business cultures;

(cid:127) unanticipated costs or liabilities, including the costs  associated  with improving the internal

controls of the acquired company;

(cid:127) diversion of management’s attention  from our core businesses;

(cid:127) adverse effects on existing business  relationships  with suppliers  and customers;

(cid:127) potential loss of key employees, particularly  those of  the purchased organizations;

(cid:127) incurring unforeseen obligations or liabilities in  connection with acquisitions; and

(cid:127) the failure to complete acquisitions even  after signing definitive agreements which,  among  other
things, would result in the expensing  of potentially  significant professional fees and other charges
in the period in which the acquisition or  negotiations are  terminated.

We  cannot assure you that we will be able to successfully identify appropriate acquisition

candidates, to integrate any businesses,  products,  technologies or  personnel that we might acquire  in
the future or achieve the anticipated benefits  of such transactions, which may  harm our business.

Our market is unpredictable and characterized  by rapid technological  changes and evolving standards
demanding a significant investment in  research and development, and,  if  we fail to  address changing market
conditions, our business and operating  results will  be harmed.

The photonics industry is characterized by extensive research and development,  rapid technological

change, frequent new product introductions,  changes in customer requirements and  evolving  industry
standards. Because this industry is subject  to rapid change, it is  difficult  to  predict its  potential size or
future growth rate. Our success in generating net sales in this industry will depend on,  among  other
things:

(cid:127) maintaining and enhancing our relationships with our customers;

(cid:127) the education of potential end-user  customers about  the benefits of lasers and laser systems; and

(cid:127) our ability to accurately predict and develop our products to meet industry standards.

For our fiscal years 2016, 2015 and 2014,  our research and development costs  were $81.8  million

(9.5% of net sales), $81.5 million (10.2% of net sales) and $79.1 million (10.0% of net sales),
respectively. We cannot assure you that our expenditures  for  research  and development will  result in
the introduction of new products or,  if such products  are introduced, that those products will  achieve
sufficient market acceptance or to generate sales to offset the costs  of  development. Our failure to
address rapid technological changes in our markets could adversely affect our business and  results of
operations.

We are exposed to lawsuits in the normal course of business which could have a  material adverse  effect on  our
business, operating results, or financial  condition.

We  are exposed to lawsuits in the normal  course of our  business,  including product liability claims,

if personal injury, death or commercial  losses occur from the  use of our products. While we  typically

37

maintain business insurance, including directors’  and  officers’  policies, litigation can  be  expensive,
lengthy, and disruptive to normal business  operations,  including the  potential  impact  of indemnification
obligations for individuals named in any  such lawsuits.  We may not, however, be able  to  secure
insurance coverage on terms acceptable  to us in  the future.  Moreover,  the results of  complex legal
proceedings are difficult to predict. An  unfavorable resolution of  a  particular lawsuit, including  a recall
or redesign of products if ultimately determined to be defective,  could have a material adverse effect
on our business, operating results, or financial  condition.

We use standard laboratory and manufacturing materials that could be considered hazardous  and  we could be
liable for any damage or liability resulting from accidental  environmental contamination  or injury.

Although most of our products do not incorporate  hazardous or toxic materials  and chemicals,
some of the gases used in our excimer  lasers  and  some of the  liquid dyes  used in some of our scientific
laser products are highly toxic. In addition, our operations involve the use of standard laboratory and
manufacturing materials that could be considered hazardous. Also, if  a facility fire were to occur  at our
Sunnyvale, California site and were to spread to a reactor used to grow semiconductor wafers, it could
release highly toxic emissions. We believe that our safety procedures for handling  and disposing of such
materials comply with all federal, state  and offshore regulations  and standards. However, the risk of
accidental environmental contamination  or injury from such materials cannot be entirely eliminated.  In
the event of such an accident involving such materials, we  could be liable for damages and  such liability
could exceed  the amount of our liability insurance coverage and  the  resources of our business which
could have an adverse effect on our  financial results or our business as a whole.

Compliance or the failure to comply with current and future environmental regulations  could cause us
significant expense.

We  are subject to a variety of federal, state,  local and foreign  environmental regulations relating to
the use, storage, discharge and disposal  of hazardous chemicals  used  during  our manufacturing process
or requiring design changes or recycling of products we manufacture.  If we fail to comply with any
present  and future regulations, we could be subject  to  future liabilities,  the suspension of  production or
a prohibition on the sale of products we manufacture. In addition, such  regulations could restrict  our
ability to expand our facilities or could require us to acquire costly equipment,  or to incur other
significant expenses to comply with environmental  regulations, including expenses associated with  the
recall of any non-compliant product and the management of historical waste.

From time to time new regulations are  enacted, and it is difficult to anticipate  how such

regulations will be implemented and  enforced.  We continue  to  evaluate the  necessary  steps  for
compliance with regulations as they are enacted.  These regulations include, for example, the
Registration, Evaluation, Authorization  and Restriction of Chemical  substances (‘‘REACH’’), the
Restriction on the Use of Certain Hazardous Substances in Electrical  and  Electronic Equipment
Directive (‘‘RoHS’’) and the Waste Electrical and Electronic  Equipment Directive (‘‘WEEE’’)  enacted
in the European Union which regulate  the  use of certain  hazardous substances in, and require the
collection, reuse and recycling of waste  from,  certain products we manufacture.  This and similar
legislation that has been or is in the  process of being enacted in Japan, China, South Korea and various
states of the United States may require  us to re-design our  products to ensure compliance with the
applicable standards, for example by  requiring  the use of  different  types of materials. These redesigns
or alternative materials may detrimentally  impact the performance of  our products, add greater testing
lead-times for product introductions  or  have other similar effects. We believe we comply with all such
legislation where our products are sold and we will continue to monitor these laws and the regulations
being adopted under them to determine  our responsibilities. In addition,  we are  monitoring legislation
relating to the reduction of carbon emissions from industrial operations to determine  whether we may
be required to incur any additional material costs  or expenses associated with our operations. We are

38

not currently aware of any such material costs or expenses. The SEC has  promulgated  rules requiring
disclosure regarding the use of certain ‘‘conflict minerals’’ mined from the Democratic  Republic  of
Congo and adjoining countries and procedures regarding  a  manufacturer’s efforts to prevent the
sourcing of such minerals. The implementation of such rules has  required us to incur additional
expense and internal resources and may continue to do so in the  future, particularly in the  event that
only a limited pool of suppliers are available to certify that products are free from ‘‘conflict  minerals.’’
Our failure to comply with any of the foregoing  regulatory requirements or contractual obligations
could result in our being directly or indirectly liable  for  costs, fines or penalties and third-party claims,
and could jeopardize our ability to conduct business in the United States and foreign countries.

Our and our customers’ operations would be seriously harmed if our logistics or facilities or those of our
suppliers, our customers’ suppliers or our  contract manufacturers were to experience  catastrophic loss.

Our operations, logistics and facilities  and those of our customers, suppliers and  contract

manufacturers could be subject to a catastrophic  loss from fire, flood,  earthquake, volcanic eruption,
work stoppages, power outages, acts  of war, pandemic  illnesses, energy  shortages, theft of assets,  other
natural disasters or terrorist activity.  A  substantial portion of our  research  and development activities,
manufacturing, our corporate headquarters and other critical  business operations are located near
major earthquake faults in Santa Clara,  California, an  area with  a history of seismic events. Any such
loss or detrimental impact to any of our  operations, logistics  or  facilities could disrupt our operations,
delay production, shipments and net sales  and result  in large expenses to repair or  replace the  facility.
While we have obtained insurance to cover most  potential  losses, after  reviewing  the costs  and
limitations associated with earthquake insurance, we have  decided not  to  procure  such insurance.  We
believe that this decision is consistent  with decisions reached by  numerous other companies located
nearby. We cannot assure you that our existing insurance  coverage  will be adequate against all other
possible losses.

Difficulties with our enterprise resource planning  (‘‘ERP’’)  system  and  other parts of  our  global information
technology system could harm our business  and results of operation.  If our network security measures  are
breached and unauthorized access is obtained to a  customer’s data or our  data  or our information technology
systems, we may incur significant legal and  financial exposure  and liabilities.

Like many modern multinational corporations, we  maintain  a global information technology
system, including software products licensed from third parties.  Any system, network or  Internet
failures, misuse by system users, the hacking  into  or disruption caused by  the unauthorized access by
third parties or loss of license rights could disrupt our ability to timely and accurately  manufacture and
ship products or to report our financial  information in compliance with  the timelines mandated  by  the
SEC. Any such failure, misuse, hacking, disruptions  or loss  would likely cause  a diversion of
management’s attention from the underlying business and could harm our operations. In addition,  a
significant failure of our global information technology  system could adversely affect our  ability to
complete an evaluation of our internal  controls and attestation activities pursuant to Section 404  of  the
Sarbanes-Oxley Act of 2002.

Our information systems are subject to  attacks, interruptions and failures.

As part of our day-to-day business, we store our data and certain data about our customers  in our
global  information technology system. While our  system is designed with access security,  if a  third  party
gains unauthorized access to our data,  including any regarding  our customers, such a security  breach
could expose  us to a risk of loss of this  information, loss  of  business,  litigation and  possible liability.
Our security measures may be breached  as a  result of third-party action, including intentional
misconduct by computer hackers, employee error, malfeasance  or otherwise.  Additionally, third  parties
may attempt to fraudulently induce employees  or customers into disclosing sensitive information  such

39

as user names, passwords or other information in  order to gain access to  our customers’ data or  our
data, including our intellectual property  and other confidential  business  information, or  our  information
technology systems. Because the techniques used to obtain unauthorized  access, or  to  sabotage systems,
change frequently and generally are not  recognized until launched  against a target,  we may be unable
to anticipate these techniques or to implement adequate  preventative  measures.  Any  unauthorized
access could result in a loss of confidence by our customers,  damage our  reputation,  disrupt  our
business, lead to legal liability and negatively impact our future sales. Additionally, such  actions could
result in significant costs associated with loss of our  intellectual property, impairment  of our  ability to
conduct our operations, rebuilding our network and systems,  prosecuting and defending litigation,
responding to regulatory inquiries or actions, paying damages or taking other remedial  steps.

Changes in tax rates, tax liabilities or tax  accounting rules could affect future  results.

As a global company, we are subject to  taxation in the  United States and various  other  countries

and jurisdictions. Significant judgment  is  required  to  determine  our worldwide  tax liabilities.  A number
of factors may affect our future effective tax rates including, but not limited to:

(cid:127) changes in the composition of earnings in countries or states with  differing  tax rates;

(cid:127) changes the assessment of the ability to recognize  our deferred tax assets  and change in the

valuation of our deferred tax liabilities;

(cid:127) the resolution of issues arising from tax audits with  various tax authorities, and in particular,  the
outcome of the German tax audits of our tax returns for fiscal years 2011  - 2014 and the U.S.
tax audit of our tax return for fiscal year 2013;

(cid:127) changes in our global structure that involve  acquisitions including the  Rofin acquisition, or an

increased investment in technology outside of the United  States  to  better align  asset ownership
and business functions with revenues and profits;

(cid:127) adjustments to estimated taxes upon finalization of various tax returns;

(cid:127) increases in expenses not deductible for tax purposes, including impairments of goodwill in

connection with acquisitions;

(cid:127) our ability to meet the eligibility requirements  for tax holidays  of limited time  tax-advantage

status;

(cid:127) changes in available tax credits;

(cid:127) changes in share-based compensation;

(cid:127) changes in the tax laws or the interpretation  of such tax laws, including the Base Erosion  Profit
Shifting  (‘‘BEPS’’) project being conducted by the Organization  for Economic  Co-operation and
Development (‘‘OECD’’);

(cid:127) changes in generally accepted accounting principles; and

(cid:127) the repatriation of non-U.S. earnings for which we have  not  previously  provided for U.S.  taxes.

We  are also engaged in discussions with various tax authorities regarding the  appropriate  level of

profitability for Coherent entities and  this  may result  in changes  to  our worldwide tax liabilities. In
addition, we are subject to regular examination  of our income tax  returns by the Internal Revenue
Service (‘‘IRS’’) and other tax authorities.  From time  to  time the United States, foreign and state
governments make substantive changes  to  tax  rules and the  application  of rules to companies, including
various announcements from the United States government  potentially impacting our ability to defer
taxes on  international earnings. We regularly  assess the likelihood of favorable or unfavorable  outcomes
resulting from these examinations to  determine the  adequacy of our provision for  income  taxes.

40

Although we believe our tax estimates  are reasonable,  there can  be  no assurance that any  final
determination will not be materially different than  the treatment reflected  in our historical income tax
provisions and accruals, which could materially and adversely affect our operating  results and financial
condition.

Changing laws, regulations and standards relating  to corporate governance and public disclosure  may create
uncertainty regarding compliance matters.

Federal securities laws, rules and regulations,  as well  as the rules and regulations of self-regulatory

organizations such as NASDAQ and the  NYSE,  require companies to maintain extensive corporate
governance measures, impose comprehensive reporting and disclosure  requirements, set  strict
independence and financial expertise standards  for audit and  other committee members and impose
civil and criminal penalties for companies and their chief executive officers,  chief financial officers and
directors for securities law violations.  These laws, rules and regulations have increased and will
continue to increase the scope, complexity and cost  of  our  corporate  governance,  reporting and
disclosure practices, which could harm our results of operations and divert management’s attention
from business operations. Changing laws,  regulations and standards relating to corporate governance
and public disclosure may create uncertainty regarding compliance matters. New or changed laws,
regulations and standards are subject  to  varying interpretations  in many cases. As  a result, their
application in practice may evolve over time. We  are committed to maintaining  high standards of  ethics,
corporate governance and public disclosure.  Complying with evolving  interpretations of new or changed
legal requirements may cause us to incur higher  costs as we revise current  practices, policies and
procedures, and may divert management  time  and  attention  from revenue generating to compliance
activities. If our efforts to comply with new  or changed  laws,  regulations and standards differ from  the
activities intended by regulatory or governing bodies due to ambiguities related to practice, our
reputation may also be harmed.

Governmental regulations, including duties, affecting the import or  export of products could  negatively affect
our net sales.

The United States and many foreign  governments  impose tariffs  and duties  on the import and

export of products, including some of those  which we  sell. In particular, given our worldwide
operations, we pay duties on certain products when they are  imported  into the United States for  repair
work as well as on certain of our products which are manufactured by our foreign subsidiaries. These
products can be subject to a duty on the product  value. Additionally, the United States and various
foreign governments have imposed tariffs, controls,  export license requirements and  restrictions on the
import or export of some technologies, especially encryption technology. From time  to  time,
government agencies have proposed additional regulation of encryption technology,  such as requiring
the escrow and governmental recovery  of  private encryption keys. Governmental regulation of
encryption technology and regulation  of  imports or exports, or our failure to obtain required  import or
export approval for our products, could  harm  our  international and  domestic  sales  and adversely  affect
our  net sales. From time to time our duty  calculations and  payments are audited by government
agencies. For example, we were audited in South Korea for customs  duties and value-added-tax for the
period March 2009 to March 2014. We  were liable for additional  payments,  duties, taxes and penalties
of $1.6 million, which we paid in the  second quarter of  fiscal 2016. Any future assessments  could  have
a material adverse effect on our business or financial position, results of operations,  or cash  flows.

In addition, compliance with the directives  of the Directorate  of Defense  Trade Controls

(‘‘DDTC’’) may result in substantial expenses  and diversion of management. Any failure to adequately
address the directives of DDTC could  result  in civil fines  or suspension  or loss  of  our  export privileges,
any of which could have a material adverse effect on our  business  or  financial position,  results of
operations, or cash flows.

41

Failure to maintain effective internal controls may cause a loss of investor confidence in the  reliability of our
financial statements or to cause us to delay  filing our periodic reports  with the  SEC and adversely affect  our
stock price.

The SEC, as directed by Section 404 of the Sarbanes-Oxley Act of 2002, adopted rules requiring

public companies to include a report  of management on internal  control over financial reporting  in
their annual reports on Form 10-K that contain an assessment by management of the  effectiveness  of
our  internal control over financial reporting. In addition, our independent  registered public  accounting
firm must attest to and report on the  effectiveness  of our internal control over financial reporting.
Although we test our internal control over financial reporting in order to ensure  compliance with  the
Section 404 requirements, our failure  to  maintain  adequate internal controls over  financial  reporting
could result in an adverse reaction in the  financial marketplace  due to a loss of  investor confidence  in
the reliability of our financial statements or  a delay  in our ability to timely file our periodic reports
with the SEC, which ultimately could  negatively  impact  our stock price.

Provisions of our charter documents and Delaware law, and  our Change-of-Control Severance Plan may have
anti-takeover effects that could prevent or  delay a change in control.

Provisions of our certificate of incorporation and bylaws may discourage, delay  or prevent a  merger

or acquisition or make removal of incumbent directors or officers more difficult. These  provisions may
discourage takeover attempts and bids for  our common stock at a premium over the market price.
These provisions include:

(cid:127) the ability of our Board of Directors  to  alter our bylaws without  stockholder  approval;

(cid:127) limiting the ability of stockholders  to call  special meetings; and

(cid:127) establishing advance notice requirements for  nominations  for election  to  our Board of Directors

or for proposing matters that can be acted on  by  stockholders at stockholder meetings.

We  are subject to Section 203 of the Delaware General Corporation Law, which prohibits a
publicly-held Delaware corporation from engaging in a  merger,  asset or stock sale or other  transaction
with an interested stockholder for a period of  three years following the date such person became an
interested stockholder, unless prior approval of our board of directors is obtained or as otherwise
provided. These provisions of Delaware  law also  may  discourage, delay or prevent someone  from
acquiring or merging with us without  obtaining  the prior approval of our  board  of  directors, which may
cause  the market price of our common  stock  to  decline. In  addition,  we have  adopted a  change of
control severance plan, which provides for  the payment  of  a cash severance benefit  to  each eligible
employee based on the employee’s position.  If a change  of  control occurs, our successor or  acquirer
will be required to assume and agree  to  perform all of our obligations  under the change of  control
severance plan which may discourage  potential acquirers or  result  in a lower stock price.

ITEM 3. LEGAL PROCEEDINGS

We  are subject to legal claims and litigation arising  in the ordinary course of business, such as
product  liability, employment or intellectual property claims, including, but not limited  to,  the matters
described below. On May 14, 2013, IMRA America (‘‘Imra’’)  filed a complaint for  patent  infringement
against two of our subsidiaries in the Regional Court of D¨usseldorf, Germany, captioned In re IMRA
America Inc. versus Coherent Kaiserslautern  GmbH et.  al. 4b O 38/13. The complaint alleges  that  the
use of certain of the Company’s lasers infringes upon EP Patent No. 754,103,  entitled ‘‘Method For
Controlling Configuration of Laser Induced  Breakdown  and  Ablation,’’ issued November 5,  1997. The
patent, now expired in all jurisdictions, is owned  by the University of Michigan and licensed to Imra.
The complaint seeks unspecified compensatory  damages, the cost of court proceedings and seeks to
permanently enjoin the Company from infringing the patent in the future. Following the filing of the
infringement suit, our subsidiaries filed  a  separate nullity action with the Federal  Patent  Court in
Munich, Germany requesting that the  court hold that  the Patent was invalid based on prior art. On
October 1, 2015, the Federal Patent Court ruled  that the German portion of the Patent was invalid.
Imra has appealed this decision to the  Federal  Court  of  Justice, the highest civil jurisdiction court in
Germany. The infringement action is  currently stayed pending the outcome of such  appeal.
Management has made an accrual with respect to this  matter and has determined, based on its current
knowledge, that the amount or range  of reasonably possible  losses  in excess of the amounts  already
accrued is not reasonably estimable.  Although we do  not  expect that such legal claims and litigation
will ultimately have a material adverse  effect on our consolidated financial position, results of
operations or cash flows, an adverse  result in one or more matters could negatively affect our results in
the period in which they occur.

The United States and many foreign  governments  impose tariffs  and duties  on the import and
export of certain products we sell. From  time to time our duty calculations and payments are audited
by government agencies. During the  second quarter of fiscal 2016, we concluded an  audit in South

44

Korea for customs duties and value added tax for the period  March 2009  to  March 2014. We paid
$1.6 million related to this matter in the second quarter of fiscal  2016 and  have no remaining accrual at
October 1, 2016.

Income Tax Audits

We  are subject to taxation and file income tax returns in the U.S. federal  jurisdiction  and in many

state and foreign jurisdictions. For U.S. federal income tax purposes, all  years  prior to fiscal 2011 are
closed. The Company agreed to extend the statutes of limitations for its fiscal  2011 and  2012 U.S.
federal tax returns to June 17, 2017 due  to an  ongoing Advanced Pricing Agreement (‘‘APA’’) between
the U.S.  and Korea. In March 2016, the  Internal  Revenue  Service (IRS) issued an audit notice and
Information Documentation Requests  (IDRs) for  fiscal 2013. The audit is  currently  in progress and the
statute of limitation was extended to December 31, 2017. In our major foreign jurisdictions and our
major state jurisdictions, the years prior to fiscal 2011  and 2012, respectively, are  closed  to  examination.
Earlier years in our various jurisdictions  may remain open  for adjustment  to  the extent that we  have
tax attribute carryforwards from those years.

In December 2011 and January 2012, three of our  German subsidiaries  received  notices  of  tax
audits for the fiscal years 2006 through  2010. The audits were completed in  the third quarter of fiscal
2016. As a result of the settlement, our  gross  uncertain  tax  positions decreased by approximately
$4.9 million. The net provision impact  of  the  adjustments  was immaterial to the  consolidated  statement
of operations.

In July 2015 and March 2016, Coherent Kaiserslautern GmbH (formerly Lumera Laser GmbH)

received tax audit notices for the fiscal  years  2010 to 2014. The audit began in August 2015. We
acquired the shares of Lumera Laser  GmbH  in December  2012 and,  pursuant to the terms  of the
acquisition agreement, we should not have  responsibility for any assessments related  to  the
pre-acquisition period. In June, 2016, Coherent Holding GmbH and Coherent  Deutschland  GmbH
each  received a tax audit notice for the fiscal years 2011 to  2014. The audit  began  in the fourth quarter
of fiscal 2016. Coherent GmbH, Coherent  LaserSystems GmbH &  Co. KG and Coherent
Germany GmbH received audit notices  for the period that they were in existence during the fiscal years
2011 through 2014 and the audit work is  scheduled to commence in  January 2017.

We  regularly engage in discussions and negotiations with  tax authorities  regarding tax matters  in

various jurisdictions and management  believes that it has adequately  provided reserves for any
adjustments that may result from tax  examinations.

In November 2015, the FASB issued  amended guidance that clarifies  that  in a classified statement
of financial position, an entity shall classify deferred  tax  liabilities  and assets as noncurrent
amounts. The new guidance supersedes ASC  740-10-45-5 which  required the  valuation allowance
for a particular tax jurisdiction be allocated between current  and noncurrent deferred tax assets for
that tax jurisdiction on a pro rata basis. We  elected  to  early adopt the  standard retrospectively in
fiscal 2016, which resulted in the reclassification of  current deferred  income tax  assets to
non-current deferred income tax assets and non-current  deferred income tax liabilities on our
consolidated balance sheets for fiscal  2016 and 2015. The impact  of  the reclassifications to deferred
tax assets and liabilities for fiscal 2014, 2013  and 2012 was immaterial.

(1) Includes $6.4 million of after tax  costs related  to  the acquisition of Rofin, a  $1.4 million after-tax
loss on our hedge of our foreign exchange risk related to the commitment  of our  term loan to
finance the acquisition of Rofin, $0.8 million after-tax interest expense on the commitment of our
term loan to finance the acquisition of Rofin and  a benefit of  $1.2 million from the renewal of the
R&D tax credit for fiscal 2015.

(2) Includes a charge of $1.3 million  after tax for  the impairment of  our investment  in SiOnyx, a
$1.3 million after-tax charge for an accrual related to an  ongoing  customs audit, a benefit  of
$1.1 million from the renewal of the R&D tax credit for  fiscal 2014 and $1.3  million gain  on our
purchase of Tinsley in the fourth quarter of fiscal  2015.

(3) Includes a tax benefit of $1.4 million  from the  renewal of the R&D tax credit for fiscal 2012.

48

(4) Includes a charge of $4.3 million  after tax related  to  the write-off  of  previously  acquired  intangible

assets and inventories, a $2.8 million  tax  benefit due to decreases  in valuation  allowances  against
deferred tax assets and a $1.6 million  tax  benefit related  to  the release  of  tax reserves and related
interest as a result of the closure of open tax years.

(5) See Note 2, ‘‘Significant Accounting Policies’’ in our Notes to Consolidated Financial Statements
under Item 15 of this annual report for an explanation of the  determination  of  the number  of
shares used in computing net income (loss) per share.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION  AND

RESULTS OF OPERATIONS

The following discussion and analysis of our  financial condition and  results of  operations should be

read in conjunction with our Consolidated Financial Statements and related notes included in  Item 8,
‘‘Financial Statements and Supplementary Data’’ in this annual report.  This discussion contains
forward-looking statements, which involve risks and uncertainties. Our actual  results could differ
materially from those anticipated in the forward-looking  statements as a result of certain  factors,
including but not limited to those discussed in  Item  1A,‘‘Risk Factors’’  and  elsewhere in  this  annual
report. Please see the discussion of forward-looking statements at  the beginning of this annual  report
under ‘‘Special Note Regarding Forward-Looking Statements.’’

KEY PERFORMANCE INDICATORS

Below is a summary of some of the quantitative  performance indicators (as defined  below) that are

evaluated by management to assess our financial performance. Some of the indicators are  non-GAAP
measures and should not be considered as an alternative to any other  measure for  determining
operating performance that is calculated  in accordance with generally accepted accounting principles.

Definitions and analysis of these performance indicators are as follows:

Bookings and Book-to-Bill Ratio

Bookings represent orders received during  the current period for products  and services.  While  we

generally have not experienced a significant  rate  of  cancellation,  bookings  are generally cancelable,
depending on the notice period, by our customers  without  substantial  penalty and, therefore, we cannot
assure all bookings will be converted  to  net sales.

The book-to-bill ratio is calculated as annual bookings divided by  annual net sales.  This is an
indication of the strength of our business  but can sometimes be impacted  by  a single large order or a
single large shipment. A ratio greater  than 1.0 indicates that demand for our products is  greater  than
what we supply in the year whereas a ratio of less  than 1.0  indicates that  demand for our  products is
less  than what we supply in the year.

50

Fiscal 2016 bookings increased 85%  from bookings  in fiscal  2015 and our book-to-bill ratio

increased from 0.95 in fiscal 2015 to  1.65 in fiscal 2016. The bookings increase included increases in  the
microelectronics (170%), materials processing (13%) and  OEM components and instrumentation (9%)
markets partially offset by decreases  in the scientific (3%)  market.  Although fiscal 2016  bookings
increased, bookings in the fourth quarter of fiscal  2016 decreased  36% from the  third quarter of  fiscal
2016, with decreases in the microelectronics, materials processing and OEM components and
instrumentation markets partially offset by increases in the scientific market.

Fiscal 2015 bookings decreased 14% from bookings  in fiscal  2014 and our book-to-bill ratio
decreased from 1.12 in fiscal 2014 to 0.95  in fiscal 2015.  The  bookings decrease included  decreases in
the microelectronics (19%), OEM components and instrumentation (14%), materials processing (8%)
and scientific (2%) markets. Although fiscal 2015 bookings decreased,  bookings in  the fourth  quarter of
fiscal 2015 increased 16% from the third quarter of fiscal 2015, with increases in all four  markets.

Backlog represents orders which we expect to be shipped  within 12 months and the current  portion

of service contracts. For a discussion of  backlog, see ‘‘RESULTS  OF OPERATIONS—BACKLOG’’.

Microelectronics

Although fiscal 2016 bookings increased  170% from bookings  in fiscal 2015 and  the book-to-bill

ratio for the year was 2.17, bookings  in  the fourth quarter of fiscal 2016 decreased 48% from  the third
quarter of fiscal 2016 primarily due to  decreased systems orders net  of higher service orders for the flat
panel  display market.

Flat panel display orders for fiscal 2016 increased 310% from orders in fiscal  2015 primarily due to

the timing and mix of order placement by customers with orders received from multiple customers for
large format Linebeam systems to be used in flexible organic light-emitting diode (OLED) production.
Fourth quarter fiscal 2016 orders were 56% lower than  those in  the third quarter of fiscal 2016
primarily due to lower orders for Linebeam  1500 and 1000 systems,  net of higher service bookings. We
expect continued fluctuations in order volumes on a  quarterly basis. After building significant flat panel
display  backlog during the first three  quarters of fiscal 2016, in the fourth quarter system  orders
temporarily returned to a more modest level  while flat panel display service orders and revenue were
very strong. Some  customers are adding  capacity to take  a larger share  of the first wave of OLED
adoption while others believe OLED  will  replace LCDs  everywhere from handsets to mobile computing
to TVs and signage. These customers  are  securing capacity to capitalize  on  these potential  trends and,
as a result, we have already booked $100 million of new  orders in the first  quarter  of  fiscal 2017, which
together with our existing backlog fills out  most of our existing fiscal 2018 capacity.

Advanced packaging (‘‘API’’) orders decreased  29% for the full fiscal  year  and fourth quarter fiscal

2016 orders decreased 12% from orders  in the third quarter of  fiscal  2016. The API market  continues
to demonstrate variability based on project specific activity. There  is an increased use  of SiPs,  or system
in package, in the newest smartphones, which increases the number of interconnects and functionality
in a smaller footprint. This will maintain pressure on the via drilling market in  the next few quarters,
but we believe the impact will be temporary since  new applications like virtual reality need large
amounts of processing power.

Orders from semiconductor capital equipment OEMs  increased  5%  for fiscal 2016 and were 26%

higher  in the fourth quarter of fiscal  2016  compared to the third quarter of  fiscal  2016 due to increases
in wafer inspection (investments for  mobile logic  chips) and  ink jet  nozzle printing applications. Service
orders and shipments remain strong  due  to  high utilization rates  in most fabs. In addition, we  saw
favorable inventory corrections at certain  customers that resulted in increased sales that we  believe are
sustainable. We do not anticipate any  significant reduction in orders from the recent collapse  of  two
proposed mergers in the semiconductor capital equipment market since they  were largely
complementary with respect to our ongoing business.

51

OEM Components and Instrumentation

Bookings in fiscal 2016 increased 9% from  fiscal 2015 and the book-to-bill ratio  for the  year was

1.08. However, orders in the fourth quarter  of fiscal 2016 decreased 3%  from orders in the third
quarter of fiscal 2016 due to lower orders for  medical  applications.

Instrumentation orders decreased 1% for the  full fiscal year and fourth  quarter  fiscal 2016 orders
increased 12% compared to the third  quarter of fiscal 2016  due to timing  of  orders.  Demand  is strong
for all submarkets in bioinstrumentation. In flow cytometry, market adoption of  the test  protocols  and
the proliferation of desktop instruments from existing  and new market entrants  are fueling growth.
Bookings for confocal microscopy were  solid.  Our  efforts in high-speed  gene  sequencing are  resulting in
increasing orders as we secure more design  wins.

Orders for medical OEM products increased 13% for  the full fiscal year 2016,  but fourth quarter

fiscal 2016 orders decreased 32% compared to the third quarter of fiscal 2016. In  spite  of  the decrease
in orders, the medical OEM market  remains  strong.  The  medical OEM market is  being  affected by
M&A activity and reorganizations within  existing customers, which is  causing changes  in demand,
inventory practices and R&D spending. From our historical experience, we believe these are  mostly
temporary factors. By contrast, the consumables  business is  robust,  suggesting the  number of
procedures being performed is stable to increasing.

Materials Processing

Annual bookings increased 13% from fiscal 2015  and fiscal 2016’s  book-to-bill  ratio was 1.05.
However, bookings in the fourth quarter of fiscal  2016 decreased  26% from the  prior quarter due to
lower orders for metal cutting and engraving applications. Bookings volumes in our materials
processing business can vary significantly from quarter  to  quarter.  In  spite of the  decrease in the  fourth
quarter of fiscal 2016, it was a record year for  orders  and  sales in  our materials  processing  business.  A
number of applications contributed to our  success including thin  metal cutting in  consumer electronics
packaging and additive manufacturing  as well as  short  pulse  processing for the automotive, medical
device and machine tool industries.

Scientific and Government Programs

Although fiscal 2016 orders decreased 3% from bookings in fiscal 2015, the book-to-bill ratio for
the year was 1.03. Orders in the fourth quarter of fiscal 2016  increased  37% from the third quarter of
fiscal 2016 as the U.S., Asian and European  markets  delivered a typically strong fourth  quarter
performance. Our Astrella(cid:4) ultrafast amplifier is the leading solution in  the research  marketplace
based upon performance and unit volumes; bookings were particularly strong in China, where  funding
for applied physics and physical chemistry is similar to that  in the U.S. The Chameleon Discovery(cid:4),
our  most advanced light source for multiphoton  imaging, had  record unit and dollar  bookings in  the
fourth quarter of fiscal 2016.

Net Sales

Net sales include sales of lasers, laser tools,  related accessories and service. Net sales for fiscal
2016 increased 7% from fiscal 2015. Net  sales for  fiscal 2015 increased  1% from fiscal 2014. For  a
description of the reasons for changes in  net sales  refer to the ‘‘Results of Operations’’  section  below.

Gross  Profit as a Percentage of Net Sales

Gross profit as a percentage of net sales (‘‘gross profit percentage’’) is calculated as gross profit for

the period divided by net sales for the  period. Gross profit  percentage for SLS increased to 48.3%  in
fiscal 2016 from 45.3% in fiscal 2015 and from 42.1%  in fiscal  2014. Gross profit percentage for CLC
increased to 35.0% in fiscal 2016 from  34.9% in fiscal 2015 and from  33.9% in fiscal 2014. For  a
description of the reasons for changes in  gross profit refer to the ‘‘Results of Operations’’ section
below.

Research and Development as a Percentage of Net Sales

Research and development as a percentage of net  sales  (‘‘R&D  percentage’’) is  calculated as

research and development expense for  the period divided by net sales  for  the period.  Management
considers R&D percentage to be an  important indicator in managing  our business as investing  in new
technologies is a key to future growth. R&D percentage decreased  to  9.5% in fiscal  2016 from 10.2%
in fiscal 2015 and 10.0% in fiscal 2014. For  a description  of the reasons for changes in R&D spending
refer to the ‘‘Results of Operations’’ section below.

Net Cash Provided by Operating Activities

Net cash provided by operating activities  shown on our  Consolidated Statements of Cash Flows
primarily represents the excess of cash  collected from billings to our  customers and other receipts  over
cash paid to our vendors for expenses  and  inventory purchases to run our  business.  We  believe that
cash flows from operations are an important performance indicator because cash generation over  the
long term is essential to maintaining  a  healthy business  and providing funds  to  help fuel  growth. For  a
description of the reasons for changes in  Net  Cash Provided by  Operating Activities  refer to the
‘‘Liquidity and Capital Resources’’ section below.

Days Sales Outstanding in Receivables

We  calculate days sales outstanding (‘‘DSO’’) in  receivables as  net receivables at the end  of  the
period divided by net sales during the  period and then multiplied  by the  number of days in the period,
using 360 days for years. DSO in receivables indicates  how well we are managing our collection of
receivables, with lower DSO in receivables resulting  in higher working capital  availability. The more
money we have tied up in receivables,  the  less money we  have available for research and  development,
acquisitions, expansion, marketing and  other  activities to grow our business. Our  DSO in receivables  for
fiscal 2016 increased to 69.6 days from  63.8 days  in fiscal 2015. The increase in  DSO  in receivables is
primarily due to a higher concentration of receivables in Asia  and  Japan where DSOs are typically
higher  and the unfavorable impact of  foreign exchange rates partially offset  by  a lower concentration of
sales in the last month of the fiscal year in all regions.

Annualized Fourth Quarter Inventory  Turns

We  calculate annualized fourth quarter inventory  turns as cost  of  sales  during  the fourth  quarter

annualized and divided by net inventories  at  the end of  the fourth  quarter.  This indicates  how well we
are managing our inventory levels, with higher inventory turns  resulting in more  working capital
availability and a higher return on our  investments in inventory.  The  more money we  have tied  up in
inventory, the less money we have available for research and development,  acquisitions,  expansion,
marketing and other activities to grow our business. Our annualized fourth quarter inventory turns for
fiscal 2016 decreased to 2.5 turns from 3.0 turns in fiscal 2015  primarily due to the planned build-up of
inventory levels in certain business units, primarily  in microelectronics, to support  increased demand  for
our  large format Linebeam systems.

Capital Spending as a Percentage of Net  Sales

Capital spending as a percentage of net  sales  (‘‘capital  spending percentage’’)  is calculated as

capital expenditures for the period divided by net sales for the period. Capital  spending  percentage
indicates the extent to which we are  expanding or improving our operations, including  investments in
technology and equipment. Management  monitors  capital spending levels  as this assists us in  measuring
our  cash flows, net of capital expenditures.  Our capital  spending  percentage increased to 5.8%  in fiscal
2016 from 2.8% in fiscal 2015 and 2.9%  in fiscal 2014.  The fiscal 2016 increase was primarily due to
increased investments to expand our  manufacturing  capacity in G¨ottingen, Germany, upgrade certain of

53

our  production facilities in California  and  New  Jersey  and higher  purchases of production-related
assets, partially offset by the impact of  higher revenues  in fiscal 2016. The  fiscal 2015 decrease  was
primarily due to lower purchases of production-related assets.

Adjusted EBITDA  as a Percentage of Net  Sales

We  define adjusted EBITDA as operating  income  adjusted for depreciation, amortization, stock-

based compensation, major restructuring  costs  and  certain other non-operating  income  and expense
items, such as costs related to the acquisition of Rofin. Key  initiatives  to reach  our  goals for EBITDA
improvements include utilization of our  Asian manufacturing locations,  rationalizing our supply  chain
and continued leveraging of our infrastructure.

We  utilize a number of different financial  measures, both GAAP  and non-GAAP,  such as  adjusted
EBITDA as a percentage of net sales, in analyzing  and assessing our  overall business performance, for
making operating decisions and for forecasting  and  planning future periods. We consider the use of
non-GAAP financial measures helpful  in  assessing our current financial performance  and ongoing
operations. While  we use non-GAAP  financial measures as a tool  to  enhance  our understanding of
certain aspects of our financial performance, we  do not consider these  measures  to  be  a substitute for,
or superior to, the information provided by  GAAP financial  measures.  We provide  adjusted EBITDA in
order to enhance investors’ understanding of our ongoing operations. This  measure  is used by some
investors when assessing our performance.

Below is the reconciliation of our net income as a percentage of net sales to our adjusted EBITDA

SIGNIFICANT EVENTS

Acquisitions and related financing

On November 7, 2016, we completed  our  previously announced  acquisition of Rofin pursuant  to

the Merger Agreement dated March 16, 2016. Rofin is one of the  world’s leading developers and
manufacturers of high-performance industrial laser sources and laser-based solutions and components.
As a condition of the acquisition, we are required to divest ourselves of Rofin’s  low power CO2  laser
business based in Hull, United Kingdom, and will report this business separately as  a discontinued
operation until it is divested. The acquisition was an all-cash transaction  at a price of $32.50 per share
of Rofin common stock. The aggregate  consideration  paid  by  us to the former  Rofin stockholders was
approximately $904.5 million, excluding related transaction fees and  expenses.  We  also paid
$15.3 million due to the cancellation of options held by employees of Rofin. We funded the  payment of

54

the aggregate consideration with a combination  of  our  available cash  on hand and  the proceeds  from
the Euro Term Loan described below.  See  Note 16,  ‘‘Subsequent Events’’ in our Notes to Consolidated
Financial Statements under Item 15 of  this annual report for further discussion of the acquisition.

On November 7, 2016, we entered into a  Credit Agreement (the ‘‘Credit Agreement’’) with

Barclays  Bank PLC (‘‘Barclays’’), Bank of America,  N.A. (‘‘BAML’’) and The Bank of Tokyo-
Mitsubishi UFJ, Ltd. (‘‘MUFG’’). The  Credit Agreement  provided for a 670.0 million  Euro  senior
secured term loan facility (the ‘‘Euro Term  Loan’’) and  a $100.0 million senior secured revolving credit
facility. On November 7, 2016, the Euro  Term Loan was drawn in full and its proceeds  were used to
finance the acquisition of Rofin and  pay  related fees and expenses. Also,  on November 7, 2016,  we
used 10.0 million Euro of the capacity  under the revolving credit facility for the issuance of a letter of
credit. See Note 16, ‘‘Subsequent Events’’  in our Notes to Consolidated Financial Statements under
Item 15 of this annual report for further discussion of the Credit Agreement.

In relation to the acquisition of Rofin, we  paid Barclays,  our financial advisor, a fee of

approximately $9.5 million, $1.0 million of which  was  paid upon  delivery of the fairness  opinion in the
second  quarter of fiscal 2016, and was recorded in the selling, general and administrative line of the
consolidated statements of operations, and the remaining portion of which was paid upon
consummation of the acquisition in the  first quarter of  fiscal 2017. We also paid Barclays,  BAML and
MUFG together approximately $17.0 million and $5.6 million for underwriting and upfront fees,
respectively, upon the close of the financing  on November 7, 2016. See Note 16, ‘‘Subsequent Events’’
in our Notes to Consolidated Financial Statements under  Item 15 of this  annual  report for  further
discussion of the completion of the acquisition and  issuance  of  the financing.

On July 24, 2015, we acquired certain assets  of Raydiance, Inc.  (‘‘Raydiance’’)  for approximately

$5.0 million, excluding transaction costs.  Raydiance manufactured complete tools and lasers  for
ultrafast processing systems and subsystems  in the precision micromachining processing  market.  The
Raydiance assets have been included  in our Specialty Lasers and  Systems  segment.

On July 27, 2015, we acquired the assets  and  certain liabilities of the Tinsley Optics (‘‘Tinsley’’)

business from L-3 Communications Corporation for approximately $4.3 million, excluding transaction
costs. Tinsley is a specialized manufacturer  of high precision optical  components and  subsystems sold
primarily in the aerospace and defense industry. Tinsley manufactures the large form  factor optics for
our  excimer laser annealing systems. The  Tinsley  assets have been included in our  Specialty  Lasers and
Systems segment.

On June 8, 2010, we invested $2.0 million  in SiOnyx, Inc.,  a privately-held company. The

investment was included in other assets and was being carried on a cost basis. During  the third quarter
of fiscal 2015 we determined that our investment  became other-than temporarily impaired. As  a result,
we recorded a non-cash charge of $2.0  million to operating  expense in  our results of operations in the
third quarter of fiscal 2015.

Stock Repurchases

On August 25, 2015, our Board of Directors  authorized a stock repurchase program  to  repurchase

up to $25.0 million of our outstanding  common stock from time to time through August 31, 2016.
During  the fourth quarter of fiscal 2015,  we repurchased and retired 437,534  shares of outstanding
common stock under this plan at an  average  price of $57.14 per share for a total of  $25.0 million.

On January 21, 2015, our Board of Directors  authorized a stock repurchase program  to  repurchase

up to $25.0 million of our outstanding  common stock from time to time through January  31, 2016.
During  the fourth quarter of fiscal 2015,  we repurchased and retired 430,675  shares of outstanding
common stock under this plan at an  average  price of $58.05 per share for a total of  $25.0 million.

55

On July 25, 2014, the Board of Directors authorized a buyback program  whereby we were

authorized to repurchase up to $25.0  million of our  common  stock from time to time  through July  31,
2015. During the first and second quarters of  fiscal  2015, we repurchased  and retired 434,114 shares of
outstanding common stock at an average  price of $57.59 per share  for a total of $25.0 million,
excluding expenses.

Backlog

Backlog represents orders which we expect to be shipped  within 12 months and the current  portion

of service contracts. Orders used to compute backlog are generally  cancelable and, depending on the
notice period, are subject to rescheduling  by our  customers without substantial penalties. Historically,
we have not experienced a significant  rate of cancellation or rescheduling, though we cannot  guarantee
that the rate of cancellations or rescheduling will  not increase in  the future.  We had a backlog  of
orders shippable within 12 months of  $605.3 million at October  1, 2016, including a  significant
concentration in the flat panel display  market  (63%) for customers which  are primarily located in Asia.

During  fiscal 2016, net sales increased by $54.9 million, or 7%, compared to fiscal  2015, including

decreases due to the unfavorable impact  of foreign exchange rates, with  sales  increases in the
microelectronics, materials processing  and  scientific and government  programs  markets  partially offset
by decreases in the OEM components and instrumentation market. Microelectronics sales increased
$48.7 million, or 12%, primarily due to higher shipments for flat panel display annealing  systems and
higher  shipments for semiconductor applications  partially offset by lower  shipments for advanced
packaging applications. Materials processing sales  increased  $13.0 million, or 12%,  during  fiscal 2016
primarily due to higher shipments for cutting,  marking  and other materials processing applications. The
increase in scientific and government  programs market sales of $0.3 million, or 0%, during  fiscal  2016
was primarily due to higher demand for  advanced research applications used by university and
government research groups. The decrease  in the OEM  components  and  instrumentation  market of
$7.2 million, or 4%, during fiscal 2016  was primarily due to lower  shipments for medical and  machine
vision  applications  partially offset by  higher shipments for military  and bio-instrumentation applications.

During  fiscal 2015, net sales increased by $7.8 million, or 1%, compared to fiscal  2014, with sales

increases in the microelectronics market partially offset  by  decreases in  the materials processing,
scientific and government programs and  OEM components and  instrumentation markets.
Microelectronics sales increased $21.6 million, or 6%, primarily due to higher shipments for  flat  panel
display  annealing systems partially offset by  lower shipments for  semiconductor and advanced packaging
applications. Materials processing sales decreased $7.6 million, or 6%, during fiscal 2015 primarily due
to lower shipments for marking, non-metal drilling and non-metal  cutting applications. The decrease in
scientific and government programs market  sales  of  $4.9 million, or 4%,  during  fiscal 2015 was
primarily due to lower demand for advanced  research  applications used by  university and government
research groups in Europe. The decrease  in the  OEM components  and instrumentation market of
$1.2 million, or 1%, during fiscal 2015  was primarily due to lower  shipments for medical and  machine
vision  applications  partially offset by  higher shipments for bio-instrumentation and forensic applications,
including the impact of the acquisitions  of Tinsley and Raydiance assets  ($2.0  million).

The timing for shipments of our higher average selling price  excimer  products in the flat panel

display  market have historically fluctuated and are in  the future  expected to fluctuate  from
quarter-to-quarter due to customer scheduling,  our  ability to manufacture these products  and/or
availability of critical component parts  and supplies. As a result, the timing to convert orders for these
products to net sales will likely fluctuate from quarter-to-quarter.

57

Looking at our prior ten years of actual results,  excluding a couple  of  recovery years, our first

quarter revenues generally ranged 2% to 12% below the fourth quarter of the  prior fiscal year.

In fiscal  2016, 2015 and 2014, one customer accounted  for 13%, 17% and 13% of  net sales,

respectively. In fiscal 2016, another customer accounted for 16% of net  sales.

Segments

We  are organized into two reportable operating segments: Specialty Lasers and Systems (‘‘SLS’’)

and Commercial Lasers and Components  (‘‘CLC’’). SLS develops  and manufactures configurable,
advanced-performance products largely serving  the microelectronics, scientific  research  and government
programs and OEM components and  instrumentation markets. CLC focuses on higher volume products
that are offered in set configurations. CLC’s  primary  markets include materials processing, OEM
components and instrumentation and  microelectronics.

Net sales for fiscal 2016 increased $54.9 million, or 7%, compared  to  fiscal  2015, with increases of
$71.7 million, or 13%, in our SLS segment and decreases  of  $16.8 million, or 7%,  in our CLC segment.
Both the fiscal 2016 increase in SLS and  decrease in CLC  segment  sales, respectively, included
decreases due to the unfavorable impact  of foreign exchange rates. Net sales for fiscal 2015  increased
$7.8 million, or 1%, compared to fiscal 2014,  with increases of $13.8  million, or 6%, in our CLC
segment and decreases of $6.0 million,  or 1%, in  our  SLS  segment. Both the fiscal 2015  increase and
decrease in CLC and SLS segment sales,  respectively, included decreases due  to  the unfavorable impact
of foreign exchange rates.

The increase in our SLS segment sales in fiscal 2016 was primarily due to higher  shipments of flat

panel  display annealing systems and higher  service revenue  as well  as higher shipments for
semiconductor and military applications partially offset by lower shipments for  medical  and advanced
packaging applications. The fiscal 2016  increase includes an increase of $11.3 million, primarily in
military and scientific applications, resulting from our acquisitions of Tinsley and  Raydiance assets  in
the fourth quarter of fiscal 2015. The decrease in  our  SLS  segment sales in fiscal 2015  was primarily
due to lower shipments for medical,  semiconductor, bioinstrumentation  and advanced packaging
applications partially offset by higher shipments of flat panel  display annealing  systems. The fiscal  2015
decrease includes an increase of $2.0  million, primarily in  military applications, resulting from  our
acquisitions of Tinsley and Raydiance assets.

The decrease in our CLC segment sales from fiscal 2015 to fiscal 2016  was  primarily due to lower
medical and advanced packaging application  sales. The  increase in our  CLC  segment sales from fiscal
2014 to fiscal 2015 was primarily due  to  higher medical, bioinstrumentation  and flat panel display
application sales.

Gross Profit

Consolidated

Our gross profit rate increased by 2.7%  to  44.5% in fiscal  2016 from 41.8% in fiscal 2015 primarily

due to favorable product margins (2.2%)  resulting  from the impact of higher volumes  in certain
business units (primarily flat panel display  applications) and  the favorable impact from foreign currency
fluctuations (primarily the Euro and Yen) as well as favorable mix  in the microelectronics market,
particularly for flat panel display applications,  net of unfavorable mix  in the OEM  components and
instrumentation market. In addition, the  margin also  benefited from  lower other costs  (0.3%) due
primarily to an accrual in the third quarter of fiscal 2015  for a customs audit in South  Korea and lower
inventory charges for excess or obsolete inventory  as well  as  lower  warranty  costs (0.2%) due to fewer
warranty events.

Our gross profit rate increased by 2.4%  to  41.8% in fiscal  2015 from 39.4% in fiscal 2014 primarily

due to favorable product margins (1.2%)  resulting  from favorable  mix in the microelectronics market
and the favorable impact from foreign  currency fluctuations net of the impact of  lower volumes  in
certain business units. In addition, the margin also benefited  from lower warranty  costs (0.6%) due to
fewer warranty events in both segments, lower other costs (0.5%)  due primarily to lower inventory
charges for excess or obsolete inventory and lower  intangibles amortization (0.1%).

Our gross profit rate has been and will continue  to  be  affected by a variety of factors including

market and product mix, pricing on volume orders, shipment volumes, our ability to manufacture
advanced and more complex products,  manufacturing efficiencies, excess and obsolete inventory write-
downs, warranty costs, amortization of intangibles, pricing by competitors or  suppliers, new product
introductions, production volume, customization and reconfiguration of systems, commodity  prices and
foreign currency fluctuations, particularly  the recent volatility of the  Euro  and a  lesser extent, the
Japanese Yen and South Korean Won.

Specialty Lasers and Systems

Our SLS gross profit rate increased by 3.0% to 48.3% in fiscal 2016  from 45.3%  in fiscal 2015
primarily due to favorable product margins (2.7%), lower warranty costs (0.2%) due to fewer warranty
events and lower intangibles amortization expense (0.1%). The 2.7% product margin improvement
resulted from the impact of higher volumes in  most business units  and the favorable impact from
foreign currency fluctuations (primarily  the Euro and Yen)  as well as  favorable mix in  the
microelectronics market, particularly  for flat panel display applications, including favorable service mix
net of unfavorable mix in the OEM components  and  instrumentation  market.

Our SLS gross profit rate increased by 3.2% to 45.3% in fiscal 2015  from 42.1%  in fiscal 2014
primarily due to favorable product margins (1.7%), lower other costs (0.8%) primarily  due  to  lower
inventory charges for excess or obsolete inventory  net of the amortization  of the inventory step up  from
the Tinsley and Raydiance asset acquisitions, lower  warranty costs (0.6%) due to fewer warranty events
and lower intangibles amortization expense (0.1%).  The 1.7% product  margin improvement  resulted
from favorable product mix in the microelectronics and OEM components  and instrumentation markets
as well as favorable service mix and the  favorable impact from foreign currency fluctuations.

Commercial Lasers and Components

Our CLC gross profit rate increased by 0.1%  to  35.0% in fiscal 2016 from 34.9%  in fiscal 2015
primarily due to lower other costs (0.8%) due to lower freight and packaging costs as well as  lower
inventory charges for excess or obsolete inventory  partially offset by unfavorable  product margin  (0.5%)
and higher warranty costs (0.2%) due to more  warranty events. The 0.5% product margin deterioration

59

resulted from unfavorable yields and  lower  volumes in certain business units partially offset by
favorable mix in the OEM components  and  instrumentation  and materials  processing  markets.

Our CLC gross profit rate increased by 1.0%  to  34.9% in fiscal 2015 from 33.9%  in fiscal 2014

primarily due to a favorable product margin  (0.5%) and lower warranty costs (0.5%) due to fewer
warranty events. The 0.5% product margin improvement resulted  from favorable mix in the OEM
components and instrumentation and  materials  processing markets partially offset by unfavorable yields
in certain business units.

Research and development

Fiscal 2016 research and development (‘‘R&D’’) expenses increased $0.3  million,  or less than 1%,

from fiscal 2015, but decreased to 9.5% of sales, compared  to  10.2%  in fiscal  2015. The $0.3 million
increase was primarily due to $2.0 million incremental spending from the asset acquisitions from
Tinsley and Raydiance, both of which were acquired in the fourth quarter of fiscal 2015, $0.3 million
higher  stock-based compensation expense and $0.3  million higher  charges for increases  in deferred
compensation plan liabilities. The increases  were  partially  offset  by $2.3 million lower project spending
including the favorable impact of foreign exchange rates, lower spending on labor and  materials and
higher  customer reimbursements. On a segment basis,  SLS spending increased $0.7 million primarily
due to the asset acquisitions from Tinsley  and  Raydiance partially offset by lower  project spending
including the favorable impact of foreign exchange rates. CLC spending decreased $1.4 million
primarily due to lower spending on projects and higher  customer  reimbursements. Corporate and other
spending increased $1.0 million primarily  due to higher  charges for  increases  in deferred  compensation
plan  liabilities and higher stock-based compensation expense.

Fiscal 2015 research and development (‘‘R&D’’) expenses increased $2.4  million,  or 3%, from

fiscal 2014, and increased to 10.2% from  10.0% of  net sales. The $2.4  million  increase was primarily
due to $2.5 million higher project spending as a  result of lower customer  reimbursements for
development projects and higher spending  on various projects net  of the favorable  impact  of  foreign
exchange rates as well as an increase  of $0.6 million from  the impact of the  acquisitions of Tinsley  and
Raydiance assets in the fourth quarter  of fiscal 2015. The  increases  were partially offset by $0.7 million
lower other spending including lower charges for  increases in deferred  compensation plan  liabilities
with the related income for increases  in deferred compensation  assets recorded in other income
(expense) and lower stock-based compensation expense.  On  a segment basis, SLS spending increased

60

$0.8 million primarily due to higher net spending  on projects due to lower  customer reimbursements
and the impact of the acquisitions of Tinsley and Raydiance  assets, in the  fourth quarter of  fiscal  2015,
partially offset by the favorable impact  of  foreign  exchange  rates. CLC spending  increased  $2.1 million
primarily due to higher spending on  projects  and  lower customer  reimbursements. Corporate and other
spending decreased $0.5 million due  to lower charges for  increases in  deferred compensation plan
liabilities and lower stock-based compensation expense.

Selling, general and administrative

Fiscal 2016 selling, general and administrative  (‘‘SG&A’’) expenses  increased  $19.3 million, or 13%,

from fiscal 2015. The increase was primarily due to a net  $8.5 million higher consulting and legal  costs
related to acquisitions in fiscal 2016 compared  to  fiscal 2015 (of which $9.8 million was related to the
acquisition of Rofin in fiscal 2016) and $6.2 million higher payroll spending primarily due to higher
variable compensation and higher sales commissions net of the favorable impact of foreign exchange
rates. In addition, the increase includes $1.8  million  higher charges for increases  in deferred
compensation plan liabilities, $1.6 million  higher stock-based compensation expense due to (1) a  higher
average stock price during fiscal 2016,  (2)  a higher number  of  restricted stock shares outstanding and
(3) the expense related to accounting  for  the transition agreement of our former CFO, and $1.2 million
higher  other net variable spending including incremental spending from the asset acquisitions of  Tinsley
and Raydiance. On a segment basis as compared to the prior year period, SLS segment expenses
increased $4.0 million primarily due to  higher payroll spending and the impact due to the asset
acquisitions from Tinsley and Raydiance  net of the favorable impact of foreign  exchange rates. CLC
spending increased $1.9 million primarily  due to higher payroll  spending net of the favorable impact of
foreign exchange rates. Spending for Corporate and other increased $13.4 million primarily due to
higher  consulting and legal costs related to acquisitions, higher charges for increases  in deferred
compensation plan liabilities, higher  stock-based compensation expense and higher payroll  spending.

Fiscal 2015 SG&A expenses decreased $4.2 million, or  3%, from fiscal 2014.  The decrease was
primarily due to $3.7 million lower charges for increases  in deferred compensation  plan liabilities with
the related income for increases in deferred compensation assets  recorded in other income (expense)
and $0.7 million lower stock-based compensation expense. The decreases were partially offset  by
$0.2 million higher other net variable spending  due to higher payroll related spending from higher
variable compensation, salaries and benefits, higher legal and consulting costs including  costs related to
acquisitions and higher bad debt expenses partially offset by  the favorable impact of foreign exchange
rates and lower demo amortization. On  a segment basis,  SLS segment expenses decreased $1.7 million
primarily due to lower variable spending.  CLC spending decreased $1.2 million primarily due to lower
variable spending. Spending for Corporate  and other  decreased $1.3  million  primarily due to lower
charges for increases in deferred compensation plan liabilities and lower stock-based compensation
expense partially offset by higher variable  spending including $1.3 million of legal and  consulting  costs
related to acquisitions and higher payroll  spending.

Gain on business combination

On July 27, 2015, we acquired the assets  and  certain liabilities of the Tinsley business from

L-3 Communications Corporation for approximately  $4.3 million, excluding transaction  costs (See
Note 3). The purchase price was lower than the fair value of net assets  purchased, resulting  in a gain of
$1.3 million recorded in our consolidated statements  of  operations for our fiscal year 2015.

Impairment of investment

On June 8, 2010, we invested $2.0 million  in SiOnyx, Inc.,  a privately-held company. The

investment was included in other assets and was being carried on a cost basis. During  the third quarter
of fiscal 2015 we determined that our investment  became other-than temporarily impaired. As  a result,

61

we recorded a non-cash impairment charge of $2.0 million to operating expense in our  results of
operations in the third quarter of fiscal 2015.

Amortization of intangible assets

Amortization of intangible assets increased $0.2 million, or  6%,  from fiscal 2015  to  fiscal  2016
primarily due to increases due to the write-off of IPR&D of $0.4  million  related to our acquisition of
Innolight and due to the asset acquisition from  Raydiance in  the fourth quarter of fiscal 2015 partially
offset by the completion of amortization  of certain  intangibles  from prior  acquisitions.

Amortization of intangible assets decreased  $0.8 million, or 22%,  from  fiscal 2014 to fiscal  2015

primarily due to the completion of amortization of certain  intangibles from prior acquisitions partially
offset by amortization due to the asset  acquisition from  Raydiance in  the fourth  quarter  of  fiscal 2015.

Other income (expense), net

Other income (expense), net, changed by $3.5  million  from  other expense  of  $1.2 million in fiscal

2015 to other expense of $4.7 million fiscal  2016. The higher expenses were primarily due to higher net
foreign exchange losses ($4.9 million)  and  $1.3 million  higher interest expense primarily  for the
commitment of our term loan to finance  the acquisition of Rofin partially offset by $2.1 million higher
gains, net of expenses, on our deferred  compensation  plan assets  and  $0.5 million  higher interest
income due to higher balances of cash and short-term investments. The higher  foreign exchange  losses
were primarily due to (1) higher unhedged  exposure in  fiscal 2016, (2)  a loss of $2.2 million on our
hedge of our foreign exchange risk related to the  commitment of our term loan to finance the
acquisition of Rofin, (3) the significant movement of rates in June 2016  due  to  the Brexit  vote  and
(4) higher forward points on our hedging  contracts.

Other income (expense), net, changed by $3.5  million  from  other income of $2.4  million in fiscal

2014 to other expense of $1.2 million in  fiscal 2015. The decrease was primarily due to $4.6 million
lower gains, net of expenses, on our deferred compensation plan  assets partially offset  by  lower net
foreign currency exchange losses ($0.9  million)  and  $0.2 million  higher interest income due to higher
balances of cash and short-term investments. Net foreign currency exchange losses decreased due to
higher  unhedged exposure in fiscal 2014  and  the significant  movement of the Japanese  Yen  versus the
Euro  in the last month of the first quarter of fiscal 2014. In addition, favorable  changes in foreign
exchange rates in the second quarter  of fiscal 2015 compared to the  timing of hedge contracts  were
partially offset by an unfavorable impact in fiscal 2015  due  to  the weakening of certain Asian  currencies
against the U.S. Dollar.

Income taxes

The effective tax rate on income before  income  taxes for  fiscal 2016 of 28.8% was lower than the
statutory rate of 35.0%. This was primarily due to differences  related  to  the benefit of income subject
to foreign tax rates that are lower than  U.S. tax rates including the Singapore  tax exemption,  the
benefit of foreign tax credits and the benefit  of federal research and development tax credits  including
renewal of the federal research and development  tax  credits for fiscal  2015. These  amounts  are partially
offset by deemed dividend inclusions  under  the Subpart F  tax rules, stock-based compensation not
deductible for tax purposes and limitations on  the deductibility of compensation under  IRC
Section 162(m).

The effective tax rate on income before  income  taxes for  fiscal 2015 of 23.3% was lower than the
statutory rate of 35.0%. This was primarily due to differences  related  to  the benefit of income subject
to foreign tax rates that are lower than  U.S. tax rates including South Korea and  Singapore tax
exemptions, the benefit of foreign tax  credits and the benefit  of  federal research and development  tax
credits including renewal of the federal research and development tax credits for fiscal 2014. These

62

amounts are partially offset by deemed dividend  inclusions under the Subpart F tax  rules,  stock-based
compensation not deductible for tax  purposes  and limitations on  the deductibility of compensation
under IRC Section 162(m).

The effective tax rate on income before  income  taxes for  fiscal 2014 of 25.4% was lower than the
statutory rate of 35.0%. This was primarily due to differences  related  to  the benefit of income subject
to foreign tax rates that are lower than  U.S. tax rates including South Korea and  Singapore tax
exemptions and the benefit of foreign tax  credits.  These amounts  are  partially offset by deemed
dividend inclusions under the Subpart F tax rules, stock-based compensation not deductible for tax
purposes  and limitations on the deductibility  of  compensation under IRC Section  162(m).

During  fiscal 2016, we increased our valuation  allowance  on deferred  tax  assets by $2.1  million to
$17.6 million primarily due to the increase  in California and  other states research and  development tax
credits which are not expected to be  recognized. During fiscal 2015, we increased our valuation
allowance on deferred tax assets by $1.2 million to $15.6  million primarily due to the  reduced  ability  to
utilize California and other states research and development tax credits.  In making the determination
to record the valuation allowance, management  considered the likelihood of future  taxable  income  and
feasible and prudent tax planning strategies to realize  deferred tax assets. In the  future, if we  determine
that we expect to realize deferred tax  assets, an  adjustment to the valuation allowance will  affect
income in the period such determination  is made.

In October 2016, Coherent Singapore received an  amended Pioneer Status  tax exemption  from the

Singapore authorities effective from fiscal 2012  through fiscal 2021. The tax  holiday continues  to  be
conditional upon our meeting certain revenue,  business spending and employment thresholds.  The
impact of this tax exemption decreased Singapore income taxes  by approximately $0.7  million in fiscal
2016. There are no tax benefits for fiscal 2015 and fiscal 2014  due to the utilization of net  operating
loss.

FINANCIAL CONDITION

Liquidity and capital resources

At October 1, 2016, we had assets classified as  cash and cash equivalents  and  short-term

investments, in an aggregate amount  of  $400.0  million, compared  to  $325.5 million at October 3, 2015.
At October 1, 2016, approximately $331.0 million of  this cash and securities  was held in certain  of  our
foreign subsidiaries, $93.1 million of which was denominated in currencies other than the U.S. dollar.
At October 1, 2016, we had approximately  $313.8 million  of  cash  held  by foreign subsidiaries where we
intend to permanently reinvest our accumulated earnings  in these entities and our  current plans do not
demonstrate a need for these funds to  support our domestic  operations. If, however,  a portion of these
funds  are needed for and distributed to our  operations  in the United States, we  may be subject to
additional U.S. income taxes and foreign  withholding taxes. An  exception  to  U.S. taxation  may be the
repatriation of foreign funds that had  been previously taxed  in the  U.S. as  Subpart  F income. The
amount of the U.S. and foreign taxes due would  depend  on the amount and manner of repatriation, as
well as the location from where the funds  are repatriated. We actively  monitor the third-party
depository institutions that hold these assets,  primarily focusing  on the  safety of principal and
secondarily maximizing yield on these  assets. We  diversify our cash and  cash  equivalents and
investments among various financial institutions, money market funds, sovereign debt and other
securities in order to reduce our exposure  should any one of these  financial institutions or financial
instruments fail or encounter difficulties. To  date, we have not experienced any  material  loss or  lack of
access to our invested cash, cash equivalents  or short-term  investments. However,  we can provide no
assurances that access to our invested cash,  cash equivalents or  short-term investments  will not be
impacted by adverse conditions in the financial markets.  In  the first  quarter of fiscal 2017,  we spent a
significant portion of our foreign funds  on the Rofin  acquisition.  We did not repatriate foreign funds to

63

our  domestic operations to fund this acquisition. We  expect to have  adequate foreign  funds  in the
future to service the acquisition debt  and  do not anticipate  any repatriation of foreign funds  to  operate
our  domestic business.

In the second quarter of fiscal 2016,  the first quarter of fiscal 2016, the second quarter of fiscal
2015 and the fourth quarter of fiscal 2014, we  converted $22.6 million, $33.0 million, $42.3 million and
$62.7 million, respectively, of cash and  securities held in certain  of  our foreign subsidiaries to U.S.
dollars and invested those funds within  a European subsidiary whose functional currency is the U.S.
dollar. At October 1, 2016, this subsidiary  had $226.8  million  of U.S. dollar  denominated investments
primarily in money market funds and commercial paper.  Accordingly, there is  no translation expense
arising from this entity holding U.S. dollar denominated  investments.  The converted funds are  not
intended to be repatriated to the U.S.  and no U.S.  tax  was triggered on the transfer of these funds to
the European subsidiary. See ITEM  7A.  QUANTITATIVE AND  QUALITATIVE DISCLOSURES
ABOUT MARKET RISK below for  more  information  about  risks and trends  related to foreign
currencies.

Sources and Uses of Cash

Historically, our primary source of cash has been provided by  operations.  Other sources of  cash in

the past three fiscal years include proceeds  received from  the sale of our stock through our employee
stock purchase plan as well as borrowings  under our domestic line of credit. Our  historical uses of cash
have primarily been for the repurchase  of our common stock, capital  expenditures and acquisitions of
businesses and technologies. Supplemental information pertaining  to  our  historical sources and uses of
cash is presented as follows and should  be  read  in conjunction  with our Consolidated Statements of
Cash Flows and notes thereto (in thousands):

Net cash provided by operating activities  decreased by $19.2  million  in fiscal 2016 compared to
fiscal 2015 and increased by $33.1 million  in fiscal 2015 compared to fiscal  2014. The decrease in cash
provided by operating activities in fiscal  2016 was primarily due to lower cash  flows  from the timing of
shipments of large systems from inventory  and lower cash  flows from accounts receivable  partially
offset by higher net income and higher accrued payroll and accounts payable  balances.  The increase in
cash provided by operating activities  in  fiscal  2015 was primarily due to higher  net income and  higher
cash flows from the timing of shipments of large systems  from inventory partially offset by lower cash
flows from prepaid income taxes and accounts receivable.  We believe  that  our existing cash,  cash
equivalents and short term investments  combined with cash  to  be  provided by operating activities,
amounts available under our revolving  credit facility  will  be  adequate to cover our working capital
needs and planned capital expenditures  for at least the  next 12 months to the extent  such items are
known or are reasonably determinable  based on  current business and  market  conditions. However,  we
may elect to finance certain of our capital expenditure requirements through other sources of capital.
We  continue to follow our strategy to further strengthen our financial position by using available cash
flow to fund operations.

64

We  intend to continue pursuing acquisition opportunities at valuations  we believe are reasonable
based upon market conditions. However, we cannot accurately predict the timing, size and  success of
our  acquisition efforts or our associated  potential capital commitments.  Furthermore, we  cannot assure
you that  we will be able to acquire businesses  on terms acceptable to us. We expect to fund future
acquisitions through additional borrowings (as in our acquisition of  Rofin), existing cash balances and
cash flows from operations. If required, we  will consider the issuance of securities. The extent  to  which
we will be willing or able to use our  common stock to make  acquisitions will depend  on its market
value at the time and the willingness  of potential sellers to accept it as  full or partial  payment.

On November 7, 2016, we entered into a  Credit Agreement by and  among us, Coherent

Holding GmbH, as borrower (the ‘‘Borrower’’), and certain  of  our direct  and indirect subsidiaries from
time to time party thereto, as guarantors, the lenders  from time to time party thereto, Barclays
Bank PLC, as administrative agent and L/C Issuer, Bank  of  America, N.A.,  as L/C  Issuer,  and The
Bank of Tokyo-Mitsubishi UFJ, Ltd., as L/C  Issuer. The Credit Agreement provided  for a  670.0 million
Euro  senior secured term loan facility (the ‘‘Euro Term Loan’’) and  a  $100.0 million senior secured
revolving credit facility (‘‘Revolving Credit Facility’’) with a  $30.0 million  letter of credit sublimit and
$10.0 million swing line sublimit. We  may increase the  aggregate revolving commitments  or borrow
incremental term loans in an aggregate principal amount of up to $150.0 million,  subject to certain
conditions, including obtaining additional commitments from the  lenders then party  to  the Credit
Agreement or new lenders. On November  7, 2016, we borrowed the full 670.0 million Euro under the
Euro  Term Loan and its proceeds were  used  to  finance  the acquisition of Rofin  and pay  related fees
and expenses. Also, on November 7, 2016,  we used 10.0  million  Euro  of the $100.0 million capacity
under the Revolving Credit Facility for  the issuance of  a letter of  credit;  the remainder  of the
Revolving Credit Facility is available.  We  expect to use future loans under the  Revolving Credit Facility,
if any, for general  corporate purposes. The  Credit Agreement replaces  our  existing $50.0 million Credit
Agreement with Union Bank of California.

Loans under the Credit Agreement bear interest,  at the  Borrower’s  option,  at a rate equal to
either (i) the London interbank offered rate (the ‘‘Eurocurrency  Rate’’)  or (ii) a base rate (the  ‘‘Base
Rate’’) equal to the highest of (x) the  federal funds rate, plus 0.50%, (y) the prime  rate then  in effect
and (z) the Eurocurrency Rate for loans  denominated in  U.S.  dollars  applicable  to  a one-month
interest period, plus 1.0%, in each case, plus an  applicable margin. The applicable margin for term
loans borrowed as Eurocurrency Rate loans, is 3.50% initially,  and  following the  first  anniversary  of  the
Closing Date ranges from 3.00% to 3.50%  depending  on the consolidated total gross leverage  ratio at
the time of determination. For term  loans borrowed as Base  Rate Loans, the applicable margin initially
is 2.50%, and following the first anniversary of the Closing Date ranges from 2.00% to 2.50%
depending upon the consolidated total  gross leverage ratio  at the  time of determination. The applicable
margin for revolving loans borrowed as  Eurocurrency Rate Loans, ranges from 3.75% to 4.25%, and
for revolving loans borrowed as Base  Rate  Loans, ranges from  2.75%  to 3.25%, in  each case, based  on
the consolidated total gross leverage  ratio at the time of determination. Interest on Base  Rate Loans is
payable quarterly in arrears. Interest  on  Eurocurrency Rate Loans is  payable at the end of  the
applicable interest period. Interest periods for Eurocurrency Rate loans may be, at the Borrower’s
option, one, two, three or six months.

The Credit Agreement requires the Borrower to make scheduled quarterly  payments on the Euro

Term Loan of 0.25% of the original principal amount of the Euro Term  Loan, with  any remaining
principal payable at maturity. A commitment fee accrues on any unused portion  of the revolving  loan
commitments under the Credit Agreement  at a  rate  of  0.375% or  0.5%  depending  on the consolidated
total gross leverage ratio at any time of determination. The Borrower is also obligated to pay other
customary fees for a credit facility of  this size  and  type.

The Credit Agreement contains customary affirmative covenants, including covenants regarding the

payment of taxes and other obligations,  maintenance  of  insurance, reporting requirements  and

65

compliance with applicable laws and regulations, and  negative covenants,  including covenants  limiting
the ability of us and our subsidiaries to, among other things, incur debt, grant liens, make investments,
make certain restricted payments, transact with  affiliates,  and sell assets.  The  Credit  Agreement also
requires us and our subsidiaries to maintain a senior secured  net leverage  ratio as  of  the last  day of
each  fiscal quarter of less of than or equal  to  3.50 to 1.00. The  Credit Agreement contains customary
events of default that include, among other things, payment defaults,  cross defaults with  certain other
indebtedness, violation of covenants, inaccuracy  of  representations and  warranties  in any  material
respect, change in  control of us and the  Borrower, judgment defaults, and  bankruptcy  and insolvency
events. If an event of default exists, the lenders may  require  the immediate payment of all Obligations,
as defined in the Credit Agreement, and  may exercise certain other rights and remedies provided for
under the Credit Agreement, the other  loan documents and applicable law. The acceleration of such
obligations is automatic upon the occurrence of a bankruptcy  and  insolvency event of default.

The aggregate consideration paid by  us  to  the former Rofin  stockholders was  approximately
$904.5 million, excluding related transaction fees and expenses.  We also paid $15.3 million due to the
cancellation of options held by employees  of Rofin.

We  paid $5.2 million of debt issuance costs in fiscal  2016 and expect to pay  approximately
$25.0 million to $30.0 million of debt issuance costs  in the first quarter  of  fiscal  2017. In the fourth
quarter of fiscal 2016, and the first quarter  of fiscal 2017, we recorded  an  interest  charge of
$1.1 million and $2.7 million, respectively,  in other income (expense) in our consolidated statement of
operations related to the debt financing  commitment.

In relation to the acquisition of Rofin, we  paid Barclays,  our financial advisor, a fee of

approximately $9.5 million, $1.0 million of which  was  paid upon  delivery of the fairness  opinion in the
second  quarter of fiscal 2016, and was recorded as SG&A expense,  and the remaining portion  of which
was paid upon consummation of the  acquisition in the first quarter of fiscal  2017.

Additional sources of cash available  to  us  were domestic and international  currency  lines  of  credit

and bank credit facilities totaling $63.2 million  as of October 1,  2016, of which $40.5 million  was
unused and available. These unsecured international credit facilities were used in  Europe and Japan
during fiscal 2016. As of October 1, 2016,  we had utilized $1.6 million of the  international  credit
facilities as guarantees. Our domestic  line of  credit consisted of a $50.0 million unsecured  revolving
credit account, under which we had drawn  $20.0 million and used $1.1 million for  letters of  credit as  of
October 1, 2016. On November 4, 2016, we  repaid the outstanding  balance, plus accrued  interest, on
our  domestic line of credit and terminated  the credit  facility.

In fiscal  2015, under plans authorized by the Board of Directors, we repurchased and retired

1,302,323 shares of outstanding common  stock  at an  average price  of $57.59 per share  for a  total  of
$75.0 million.

Our ratio of current assets to current liabilities was 4.0:1 at October 1,  2016, compared to 5.3:1  at

October 3, 2015. The decrease in our  ratio is primarily due  to  increases in other current liabilities,
short-term borrowings, taxes payable and accounts  payable partially offset by increases in  cash and
short-term investments, inventories, accounts receivable and prepaid expenses and other assets. Our
cash and cash equivalents, short-term investments  and working capital  are as follows (in thousands):

Because of the uncertainty as to the timing of such payments, we have excluded cash payments
related to our contractual obligations for  our deferred compensation plans aggregating  $30.0 million at
October 1, 2016.

As of October 1, 2016, we recorded  gross  unrecognized tax benefits of $20.6  million including
gross  interest and  penalties of $0.2 million. As of October 3, 2015,  we recorded  gross unrecognized tax
benefits of $24.3 million including gross  interest and penalties  of $1.8 million. Both gross unrecognized
tax benefits and gross interest and penalties are classified as non-current liabilities in the consolidated
balance sheet. At this time, we are unable  to make a reasonably  reliable estimate of the timing of
payments in individual years due to uncertainties  in  the timing of tax audit outcomes. As a result, these
amounts are not included in the table  above.

Changes in financial condition

Cash provided by operating activities in fiscal 2016 was $105.3 million, which included net income
of $87.5 million, depreciation and amortization of $34.4 million, stock-based compensation expense of
$20.2 million and $0.9 million other,  partially  offset by cash used by  operating assets and liabilities of
$27.9 million (primarily increases in inventories net of increases in accrued payroll and deferred
income) and increases in net deferred  tax assets  of $9.8  million.  Cash provided by operating activities in
fiscal 2015 was $124.5 million, which included net income  of $76.4  million, depreciation and
amortization of $33.1 million, stock-based compensation expense of $18.2 million, the  impairment of
our  investment in SiOnyx of $2.0 million, decreases  in  net deferred tax assets of  $0.8 million and
$0.6 million other, partially offset by cash used by operating assets and liabilities of $5.3 million and the
net effect of the gain from acquisition of  Tinsley asset  of $1.3 million.

Cash provided by investing activities  in fiscal 2016 of $103.4 million included $152.2 million net
sales and maturities of available-for-sale securities partially offset by $48.8  million, net, used to acquire
property and equipment, purchase and  upgrade  buildings, net of proceeds from  dispositions. Cash
provided by investing activities in fiscal  2015 of $3.2 million included $33.5 million net sales and
maturities of available-for-sale securities  partially offset by  $21.0 million, net, used to acquire  property
and equipment and improve buildings  net of proceeds from  dispositions and $9.3 million used to
acquire Tinsley and Raydiance assets.

Cash provided by financing activities  in fiscal 2016  was  $17.2  million, which included $20.0 million

net borrowings, and $7.8 million generated from our  employee stock option and purchase plans
partially offset by $5.4 million outflows  due to net settlement of  restricted stock and $5.2 million of
debt issuance costs. Cash used in financing activities in fiscal 2015 was $73.0 million, which included
$75.0 million repurchases of common  stock and $5.3 million outflows due to net settlement  of

67

restricted stock partially offset by $7.3  million generated from  our employee stock option  and purchase
plans.

Changes in exchange rates in fiscal 2016 resulted in a decrease in cash balances of $2.2  million.

Changes in exchange rates in fiscal 2015  resulted in a decrease in cash balances of $15.2  million.

RECENT ACCOUNTING PRONOUNCEMENTS

See Note 2. ‘‘Significant Accounting Policies’’ in  the Notes to Consolidated  Financial Statements
for a full description of recent accounting  pronouncements, including the respective dates of adoption
or expected adoption and effects on  our  consolidated financial position, results of operations and cash
flows.

APPLICATION OF CRITICAL ACCOUNTING POLICIES

Our discussion and analysis of financial  condition  and  results of operations are  based upon our

consolidated financial statements, which  have  been prepared in accordance  with accounting principles
generally accepted in the United States of  America and  pursuant to the rules and regulations  of the
SEC. The preparation of these financial  statements requires  management to make estimates  and
assumptions that affect the reported amounts  of assets and liabilities and disclosure of  contingent assets
and liabilities at the date of the financial  statements  and  the reported amounts of revenues and
expenses during the reporting period.  We have  identified the following as the  items  that  require the
most significant judgment and often involve  complex estimation:  revenue  recognition, accounting  for
long-lived assets (including goodwill and intangible assets), inventory valuation, warranty reserves,
stock-based compensation and accounting for  income taxes.

Revenue Recognition

We  recognize revenue when all four  revenue recognition criteria  have been met: persuasive
evidence of an arrangement exists, the  product has  been delivered or  the  service  has been  rendered,
the price is fixed or determinable and collection is probable.  Revenue from  product sales is  recorded
when all of the foregoing conditions are met and  risk  of  loss  and title passes to the customer. Our
products typically include a warranty and the estimated cost of product  warranty claims  (based  on
historical experience) is recorded at the  time  the sale is recognized. Sales to customers are generally
not subject to any price protection or return  rights.

The majority of our sales are made to original equipment manufacturers (‘‘OEMs’’), distributors,

representatives and end-users in the non-scientific market.  Sales  made to these customers do not
require installation of the products by  us and are not subject to other post-delivery obligations,  except
in occasional instances where we have  agreed to perform  installation  or provide training. In those
instances, we defer revenue related to  installation  services or training  until these  services have been
rendered. We allocate revenue from multiple element arrangements to the various  elements based upon
fair values or a selling price hierarchy,  as more fully described in Note  2, ‘‘Significant Accounting
Policies—Revenue Recognition,’’ in our consolidated financial statements.

Should changes in conditions cause management to determine these criteria  are not met  for
certain future transactions, revenue recognized for  any reporting  period could be adversely  affected.
Failure to obtain anticipated orders due  to  delays or  cancellations of  orders  could  have a material
adverse effect on our revenue. In addition, pressures from  customers to reduce  our  prices or to modify
our  existing sales terms may have a material adverse  effect on our  revenue in  future periods.

Our sales to distributors, representatives and  end-user  customers typically  do not have customer
acceptance provisions and only certain  of  our  sales  to  OEM customers and  integrators have customer
acceptance provisions. Customer acceptance  is generally limited to performance under  our published

68

product  specifications. For the few product sales that have customer acceptance provisions because  of
higher  than published specifications, (1)  the products are tested  and  accepted by the customer at our
site or the customer accepts the results of our  testing program prior  to  shipment to the customer, or
(2) the revenue is deferred until customer  acceptance  occurs.

Sales to end-users in the scientific market typically  require installation and, thus, involve
post-delivery obligations; however our  post-delivery  installation  obligations are not essential to the
functionality of our products. We defer  revenue related  to installation  services until completion of these
services.

For most products, training is not provided; therefore,  no post-delivery training  obligation exists.

However, when training is provided to  our customers,  it is typically priced separately and  recognized as
revenue as these services are provided.

For multiple element arrangements which include extended maintenance contracts,  we allocate  and

defer the amount of consideration equal to the separately stated  price and  recognize revenue on a
straight-line basis over the contract period.

Long-Lived Assets and Goodwill

We  evaluate long-lived assets and amortizable intangible  assets whenever events or  changes in

business circumstances or our planned  use of assets  indicate  that their carrying amounts may  not  be
fully recoverable or that their useful  lives are no longer  appropriate. Reviews are  performed  to
determine whether the carrying values of the assets are impaired based on  comparison  to  the
undiscounted expected future cash flows identifiable  to  such long-lived  and  amortizable  intangible
assets. If the comparison indicates that impairment exists,  the impaired asset is  written  down to its fair
value.

We  have determined that our reporting units  are the same as our operating  segments as each

constitutes a business for which discrete financial information is available  and for which  segment
management regularly reviews the operating results. We  make this determination in  a manner
consistent with how the operating segments  are managed.  Based  on  this  analysis, we have identified two
reporting units which are our reportable  segments: SLS and CLC.

Goodwill is tested for impairment on  an annual  basis and between annual tests in certain

circumstances, and written down when impaired (see Note 7 ‘‘Goodwill and Intangible  Assets’’ in  the
Notes to Consolidated Financial Statements). We generally  perform our annual impairment  tests  during
the fourth quarter of each fiscal year using the  opening balance sheet as  of the first day of the  fourth
fiscal quarter, with any resulting impairment recorded in  the fourth quarter of the fiscal year.

In fiscal  2014, 2015 and 2016, we conducted a qualitative assessment of the goodwill  in the SLS
reporting unit during the fourth quarter of each fiscal year using the  opening balance sheet as  of  the
first day of the fourth quarter and concluded that  it was more  likely than not that the fair value  of  the
reporting unit exceeded its carrying amount.  In assessing  the qualitative factors, we considered the
impact of these key factors: macroeconomic conditions, fluctuations  in foreign  currency,  market  and
industry conditions, our operating and competitive  environment, regulatory and political developments,
the overall financial performance of our reporting units including cost  factors  and budgeted-to-actual
revenue results. We also considered our  market  capitalization, stock price performance and the
significant excess calculated in the prior  year between estimated fair  value  and the  carrying value of
SLS. Based on our assessment, goodwill  in the  SLS reporting unit  was not impaired  as of the first day
of the fourth quarter of fiscal 2014, 2015 or 2016. As  such, it was not necessary to perform the two-step
goodwill impairment test at that time in any of those fiscal years.

For our CLC reporting unit we elected to bypass the qualitative assessment in fiscal 2014,  2015

and 2016 and proceeded directly to performing the first  step of goodwill impairment.  Accordingly, we

69

performed the Step 1 test during the  fourth quarter  of  fiscal 2016, 2015  and 2014. We determined the
fair value of the reporting unit for the Step  1 test using  a 50-50% weighting of the  Income (discounted
cash flow) approach and Market (market comparable) approach. The  Income approach utilizes the
discounted cash flow model to provide  an estimation  of fair value based on the  cash flows that a
business expects to generate. These cash  flows are based  on forecasts  developed internally by
management which are then discounted  at  an after  tax rate of  return  required by equity and  debt
market participants of a business enterprise. This rate of return or cost of capital is weighted based on
the capitalization of comparable companies. The Market  approach determines fair  value by comparing
the reporting units to comparable companies in similar lines of business  that  are publicly traded. Total
Enterprise Value (TEV) multiples such  as TEV to revenues and TEV to earnings  (if applicable)  before
interest and taxes of the publicly traded  companies are calculated.  These multiples are then  applied to
the reporting unit’s operating results to obtain an estimate of fair value. Each of these two approaches
captures aspects of value in each reporting unit. The  Income approach captures our  expected future
performance, and the Market approach captures  how investors view the  reporting units through  other
competitors. We believe these valuation  approaches are proven valuation techniques and methodologies
for our  industry and are widely accepted by investors. As neither  was  perceived by us to deliver any
greater indication of value than the other,  and  neither approach individually computed a fair  value less
than the carrying value of the segment, we  weighted  each  of  the approaches equally. Management
completed and reviewed the results of the  Step 1 analysis and concluded that a Step  2 analysis  was not
required as the estimated fair value of the CLC reporting  unit was substantially in  excess  of its  carrying
value. Between the completion of that testing  and  the end of the  fourth quarter of  fiscal  2016, we
noted no indications of impairment or  triggering  events for either reporting unit to cause us to review
goodwill for potential impairment.

At October 1, 2016, we had $101.5 million of goodwill ($95.1 million SLS and $6.4 million in
CLC), $13.9 million of purchased intangible  assets and $127.4 million of property and equipment  on
our  consolidated balance sheet.

Inventory Valuation

We  record our inventory at the lower of cost  (computed on  a first-in, first-out basis) or market. We
write-down our inventory to its estimated  market  value based on  assumptions about future  demand and
market conditions. Inventory write-downs are generally recorded within guidelines  set by management
when the inventory for a device exceeds  12 months of its demand or when management has  deemed
parts are no longer active or useful. If actual market conditions are less favorable  than those projected
by management, additional inventory write-downs may be required which  could  materially affect our
future results of operations. Due to rapidly changing forecasts and orders, additional write-downs for
excess or obsolete inventory, while not  currently expected, could be required  in the future. In  the event
that alternative future uses of fully written down inventories  are identified, we may experience better
than normal profit margins when such inventory  is sold. Differences between actual results and
previous estimates of excess and obsolete  inventory  could  materially affect  our  future results of
operations. We write-down our demo  inventory by  amortizing the  cost of demo inventory  over a twenty
month period starting from the fourth month after such  inventory is  placed in  service.

Warranty Reserves

We  provide warranties on the majority of our product  sales and allowances for estimated warranty
costs are recorded during the period of  sale. The determination of  such allowances  requires us to make
estimates of product return rates and  expected  costs to repair or replace the products under warranty.
We  currently establish warranty reserves based on historical  warranty costs for each product  line. The
weighted average warranty period covered is approximately  15 months. If actual  return  rates  and/or

70

repair and replacement costs differ significantly  from our estimates, adjustments to cost of  sales may  be
required in future periods.

Stock-Based Compensation

We  account for stock-based compensation using fair value.  We estimate  the fair value of

performance restricted stock units granted  using a Monte  Carlo simulation model. We use  historical
data to  estimate pre-vesting option forfeitures and record  stock-based compensation  expense only for
those awards that are expected to vest.  We value service-based restricted  stock units  using the intrinsic
value method and amortize the value on  a straight-line basis  over the restriction  period. We  value
performance restricted stock units using  a Monte Carlo simulation model and  amortize the value over
the performance period, with no adjustment  in future periods,  based upon  the actual shareholder
return  over the performance period.

U.S. Generally Accepted Accounting Principles  (‘‘GAAP’’)  requires the use  of option  pricing
models  that were not developed for use in valuing  employee stock options. The Black-Scholes option-
pricing model was developed for use in estimating the  fair value of short-lived exchange traded  options
that have no vesting restrictions and  are  fully  transferable. In addition, option-pricing models require
the input of highly subjective assumptions, including  the options expected life,  the expected  price
volatility of the underlying stock and an estimate of expected forfeitures. Our  computation of expected
volatility considers historical volatility  and  market-based implied volatility. Our estimate of  expected
forfeitures is based on historical employee  data and could  differ  from actual forfeitures.

See Note 12 ‘‘Employee Stock Award and Benefit Plans’’ in the notes to  the Consolidated
Financial Statements for a description of  our stock-based employee  compensation  plans and the
assumptions we use to calculate the fair value  of  stock-based employee compensation.

Income Taxes

As part of the process of preparing our  consolidated financial statements,  we are  required to
estimate our income tax provision (benefit)  in each of the  jurisdictions  in which we operate. This
process involves us estimating our current income tax provision (benefit)  together  with assessing
temporary differences resulting from  differing treatment of items  for tax  and accounting  purposes.
These differences result in deferred tax assets  and  liabilities, which are  included within our consolidated
balance sheets.

We  record a valuation allowance to reduce our deferred  tax assets  to  an amount that more likely

than not will be realized. While we have  considered future  taxable income and  ongoing prudent and
feasible tax planning strategies in assessing the  need  for the  valuation  allowance,  in the event we were
to determine that we would be able to realize our deferred tax assets  in the future in excess of  our net
recorded  amount, an adjustment to the  allowance  for  the deferred tax asset  would increase income in
the period such determination was made. Likewise, should we determine that we  would not be able to
realize all or part of our net deferred tax asset in the future, an adjustment to the valuation allowance
for the deferred tax asset would be charged to income in  the period such determination was made.

During  fiscal 2016, we increased our valuation  allowance  on deferred  tax  assets by $2.1  million to

$17.6 million, primarily due to the increase  in California and  certain state research and  development
tax credits, which are not expected to  be  recognized. The Company had U.S. federal deferred tax assets
related to research and development credits, foreign  tax  credits and other tax attributes that can be
used to offset federal taxable income in  future periods. These  credit carryforwards will expire if they
are not used within certain time periods.  As of October 1, 2016, management determined  that  there is
sufficient positive evidence to conclude that it  is more likely than not sufficient taxable income will
exist in the future allowing us to recognize these deferred  tax  assets. It is possible that some or all
these attributes could ultimately expire  unused. If facts and  circumstances change in  the future,

71

management may determine at that time  a valuation allowance is necessary. A valuation  allowance
would materially increase our tax expense in  the period  applied and would  adversely affect  our results
of operations and  statement of financial condition. Changes in the Company’s  underlying  facts or
circumstances, such as the impact of  the Rofin-Sinar merger, will be assessed  as they  occur and the
Company will re-evaluate its position  accordingly.

Federal and state income taxes have not been provided on  a portion of the unremitted earnings of
foreign subsidiaries because such earnings are intended  to  be  permanently reinvested. The total amount
of unremitted earnings (including accumulated translation adjustments) of foreign subsidiaries for which
we have not yet recorded federal and  state income taxes was approximately $574.0  million  at fiscal
2016 year-end. The amount of federal and state income taxes that would  be payable  upon repatriation
of such earnings is not practicably determinable. We have  not,  nor  do we  anticipate the need to,
repatriate funds to the United States to satisfy domestic liquidity needs arising in the  ordinary course of
business.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES  ABOUT MARKET  RISK

Market risk disclosures

We  are exposed to market risk related  to  changes in interest rates and foreign currency exchange

rates. We do not use derivative financial instruments for speculative or trading  purposes.

Interest rate sensitivity

A portion of our investment portfolio is  composed of fixed income securities. These securities are
subject to interest rate risk and will fall in value if market interest rates increase. If interest  rates  were
to increase immediately (whether due to changes in overall market rates or credit worthiness of the
issuers of our individual securities) and  uniformly by  10% from  levels at fiscal 2016 year-end, the fair
value of the portfolio, based on quoted  market  prices in  active  markets involving similar  assets, would
decline  by an immaterial amount due to their short-term maturities. We  have the ability to generally
hold our fixed income investments until maturity  and therefore  we  would not expect  our  operating
results or cash flows to be affected to any significant degree by the  effect of a sudden change in market
interest rates on our securities portfolio. If necessary, we may sell short-term investments  prior to
maturity to meet our liquidity needs.

At fiscal 2016 year-end, the fair value  of  our available-for-sale debt securities  was  $25.1 million, all

of which was classified as short-term investments. There were no gross  unrealized gains and losses on
available-for-sale debt securities at fiscal  2016 year-end. At fiscal 2015  year-end, the  fair value  of our
available-for-sale debt securities was  $178.4  million,  all of which was classified as short-term
investments. Gross unrealized gains and losses on available-for-sale debt securities were  $1.1 million
and $(2,000), respectively, at fiscal 2015  year-end.

Foreign currency exchange risk

We  maintain operations in various countries outside of the United States and have foreign

subsidiaries that manufacture and sell our products in various global  markets. The  majority of our sales
are transacted in U.S. dollars. However, we do generate revenues in  other  currencies, primarily  the
Euro,  the Japanese Yen, the South Korean  Won and the  Chinese RMB. Additionally, we have
operations in different countries around the world with costs incurred in  other  local currencies, such  as
British Pound Sterling, Singapore Dollars  and Malaysian Ringgit. As  a  result, our earnings,  cash flows
and cash balances are exposed to fluctuations in foreign currency  exchange rates.  For example,  we have
significant manufacturing operations  in  Europe  so that a  weakening Euro is advantageous to our
financial results. We attempt to limit these exposures through  financial  market  instruments. We utilize
derivative instruments, primarily forward  contracts with maturities  of two  months or less, to manage

72

our  exposure associated with anticipated cash  flows  and net  asset  and liability  positions  denominated in
foreign currencies. Gains and losses on the  forward contracts are mitigated by gains and losses  on the
underlying instruments. We do not use  derivative financial  instruments  for trading purposes.

On occasion, we enter into currency  forward exchange  contracts to hedge specific anticipated
foreign currency denominated transactions generally expected to occur within the next  12 months.
These cash flow hedges are designated  for hedge  accounting treatment  and  gains and  losses on  these
contracts are recorded in accumulated other comprehensive income in  stockholder’s  equity and
reclassified into earnings at the time that  the related  transactions being hedged are recognized  in
earnings. See Note 6 ‘‘Derivative Instruments and Hedging Activities’’.

On August 1, 2016, we purchased forward contracts totaling 670.0 million Euro, with  a value  date
of November 30, 2016, to limit our foreign  exchange  risk related to the commitment of our term loan
(denominated in Euros) in an amount  of the Euro equivalent of $750.0 million to finance the U.S.
dollar payment for the acquisition of  Rofin. In the fourth quarter of  fiscal  2016, we  recognized an
unrealized loss of $2.2 million on these hedges.  Subsequent to October 1, 2016, we settled these hedges
at a net gain of $3.1 million, resulting  in  a realized gain of  $5.3 million  in the first quarter of fiscal
2017. See Note 6 ‘‘Derivative Instruments and Hedging Activities’’  to  our consolidated financial
statements in Part IV of this report.

We  do not anticipate any material adverse effect on our consolidated financial position, results  of

operations or cash flows resulting from the  use of these instruments.  There can be no assurance that
these strategies will be effective or that  transaction losses can be minimized or forecasted accurately.
While we model currency valuations  and  fluctuations,  these  may  not  ultimately be accurate. If a
financial counterparty to any of our hedging arrangements  experiences  financial difficulties  or is
otherwise unable to honor the terms  of  the  foreign currency hedge,  we  may experience material
financial losses. In the current economic environment, the risk of failure of a financial party  remains
high.

At October 1, 2016, approximately $331.0 million of  our cash, cash equivalents  and short-term
investments were held outside the U.S.  in  certain of  our foreign operations, $93.1 million of which  was
denominated in currencies other than the U.S. dollar. See Note 16,  ‘‘Subsequent  Events’’ in our  Notes
to Consolidated Financial Statements under Item  15 of this  annual report for  further discussion of the
completion of our acquisition of Rofin and the  use of cash to finance the acquisition.

A hypothetical 10% change in foreign currency  rates on our forward contracts  would not have a

material impact on our results of operations, cash flows  or financial position.

The following table provides information about our foreign exchange forward  contracts at

October 1, 2016. The table presents the  weighted  average contractual foreign currency exchange  rates,
the value of the contracts in U.S. dollars  at the  contract exchange rate as  of  the contract  maturity date
and fair value. The U.S. fair value represents the fair value  of the contracts valued at October  1, 2016
rates.

ITEM 9A. CONTROLS AND PROCEDURES

Management’s Evaluation of Disclosure Controls and Procedures

We  have evaluated the effectiveness of the design  and operation of  our disclosure  controls and
procedures, as such term is defined in  Rule  13a-15(e)  under the  Securities  Exchange Act  of  1934, as of
the end of the period covered by this  annual  report (‘‘Evaluation Date’’). The controls evaluation  was
conducted under the supervision and with the  participation of management,  including our Chief
Executive Officer and Chief Financial  Officer. Based on this evaluation,  our  Chief Executive Officer
and Chief Financial Officer concluded  as of the Evaluation Date  that our  disclosure controls and
procedures were effective in providing reasonable assurance that  information required  to  be  disclosed
by us in reports that we file or submit under  the Securities Exchange Act  of 1934, as  amended, is
(i) recorded, processed, summarized  and  reported  within the time periods specified in  the Securities
and Exchange Commission’s rules and  forms and (ii) accumulated and communicated to our
management, including our Chief Executive Officer and Chief Financial Officer,  as appropriate, to
allow timely decisions regarding required  disclosures.

Management’s Report on Internal Control Over Financial Reporting

Management, including our Chief Executive Officer and  Chief Financial  Officer, is responsible for
establishing and maintaining adequate internal control  over  financial reporting (as defined in  Exchange
Act Rules 13a-15(f) and 15d-15(f)) for  the Company.

Management assessed the effectiveness of our internal control over financial  reporting as of
October 1, 2016, utilizing the criteria  set  forth by  the Committee of Sponsoring  Organizations  of the
Treadway Commission (‘‘COSO’’) in  Internal Control-Integrated  Framework (2013). Based on the
assessment by management, we determined  that our  internal  control over financial reporting was
effective as of October 1, 2016. The effectiveness of our internal control  over  financial  reporting as of
October 1, 2016 has been audited by  Deloitte & Touche LLP, our independent  registered public
accounting firm, as stated in their report  which appears below.

Inherent Limitations Over Internal Controls

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 (‘‘GAAP’’). Because  of its
inherent limitations, internal control over  financial reporting  may  not prevent or  detect  misstatements.
Also, projections of any evaluation of effectiveness for 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.  Our internal control  over  financial  reporting is
designed to provide reasonable assurance  regarding  the reliability of financial reporting  and the
preparation of the financial statements for  external purposes  in accordance with  GAAP. Our  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 our assets;

(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 our receipts and expenditures are being made only in  accordance  with
authorizations of our management and directors; and

(iii) provide reasonable assurance regarding prevention or timely detection of  unauthorized

acquisition, use, or disposition of our assets  that could  have a material  effect  on the financial
statements.

75

Management, including our CEO and CFO, does  not  expect  that our internal controls will prevent

or detect all errors and all fraud. A control system, no matter how well  designed 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 internal  controls can  provide absolute assurance that all control  issues
and instances of fraud, if any, have been  detected. Also, any  evaluation of the  effectiveness  of  controls
in future periods are subject to the risk  that those internal controls may become inadequate because of
changes in business conditions, or that the degree of compliance with  the policies or procedures may
deteriorate.

Changes  in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the

quarter ended October 1, 2016 that have materially affected, or are reasonably likely to materially
affect, our internal control over financial  reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders  of
Coherent, Inc.
Santa Clara, CA

We  have audited the internal control over  financial reporting of  Coherent,  Inc. and  its  subsidiaries

(collectively, the ‘‘Company’’) as of October 1,  2016, based  on the criteria established  in Internal
Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations  of  the
Treadway Commission. The Company’s  management  is responsible for  maintaining effective internal
control over financial reporting and for  its assessment of the effectiveness of internal  control over
financial reporting included in the accompanying Management’s Report  on Internal Control  Over
Financial Reporting. Our responsibility  is to express an opinion  on the Company’s internal  control over
financial reporting based on our audit.

We  conducted our audit in accordance with the standards of  the Public Company Accounting
Oversight Board (United States). Those  standards require that we  plan and perform the audit to obtain
reasonable assurance about whether  effective  internal control over financial reporting was maintained
in all material respects. Our audit included  obtaining an understanding  of internal control  over
financial reporting, assessing the risk that a  material weakness exists, testing and evaluating the design
and operating effectiveness of internal control based  on the assessed risk, and performing such other
procedures as we considered necessary in  the circumstances. We  believe that our audit provides a
reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed by, or  under the

supervision of, the company’s principal executive and principal financial  officers,  or persons performing
similar functions, and effected by the company’s board of directors, management, and other personnel
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
(1) pertain to the maintenance of records  that, in  reasonable  detail,  accurately and  fairly reflect the
transactions and dispositions of the assets of  the company;  (2) 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
(3) 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 the inherent limitations of internal  control over  financial reporting, including  the
possibility of collusion or improper management override of controls, material misstatements  due  to
error or fraud may not be prevented or detected  on a  timely basis. Also, projections of any evaluation
of the effectiveness of the internal control over financial reporting to future periods are subject  to  the
risk that the controls may become inadequate  because of changes in conditions, or  that  the degree of
compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal  control  over

financial reporting as of October 1, 2016, based  on the criteria  established  in Internal Control—
Integrated Framework (2013) issued by the Committee of Sponsoring  Organizations  of  the Treadway
Commission.

We  have also audited, in accordance  with the standards of  the Public Company Accounting
Oversight Board (United States), the  consolidated financial statements as  of  and for the year ended
October 1, 2016, of the Company and  our  report dated November 29, 2016, expressed an unqualified
opinion on those consolidated financial  statements.

STATEMENT OF MANAGEMENT RESPONSIBILITY

Management is responsible for the preparation,  integrity, and objectivity of the Consolidated
Financial Statements and other financial  information included in  the Company’s  2016 Annual Report
on Form 10-K. The Consolidated Financial Statements have been prepared in conformity with U.S.
generally  accepted accounting principles and reflect  the  effects  of certain estimates and judgments
made by management. It is critical for investors and other  readers  of the Consolidated Financial
Statements to have confidence that the financial information that we provide is timely, complete,
relevant and accurate.

Management, with oversight by the Company’s Board of Directors, has  established and maintains a

corporate culture that requires that the Company’s affairs be conducted to the highest  standards of
business ethics and conduct. Management also maintains a system of  internal controls that is designed
to provide reasonable assurance that  assets are safeguarded  and that transactions are  properly recorded
and  executed in accordance with management’s authorization. This system is regularly monitored
through  direct management review, as  well as extensive audits conducted  by  internal auditors
throughout the organization.

Our Consolidated Financial Statements as of and for the year ended October 1, 2016  have been
audited by Deloitte & Touche LLP, an independent  registered  public accounting firm. Their  audit was
conducted in accordance with the standards  of the Public Company Accounting Oversight  Board
(United States) and included an integrated  audit under such standards.

The Audit Committee of the Board of Directors meets regularly  with management, the internal

auditors and the independent registered public accounting firm  to  review accounting, reporting,
auditing and internal control matters. The Audit Committee  has direct and private  access to both
internal and external auditors.

See  Item 9A for Management’s Report  on Internal Control  Over  Financial Reporting.

We are committed to enhancing shareholder value and fully understand and  embrace our fiduciary
oversight  responsibilities. We are dedicated  to  ensuring that  our high standards  of  financial  accounting
and  reporting as well as our underlying system  of  internal controls are maintained. Our  culture
demands integrity and we have the highest confidence  in our  processes, internal controls, and people,
who are objective in their responsibilities and operate under the highest  level of ethical standards.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders  of
Coherent, Inc.
Santa Clara, CA

We  have audited the accompanying consolidated balance sheets of Coherent, Inc.  and its

subsidiaries (collectively, the ‘‘Company’’) as of  October 1, 2016 and October 3, 2015, and the related
consolidated statements of operations, comprehensive  income, stockholders’ equity, and  cash flows for
each  of the three years in the period  ended  October 1,  2016. These consolidated financial  statements
are the responsibility of the Company’s  management. Our responsibility is  to  express  an opinion on
these consolidated financial statements  based on  our  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 audit to obtain
reasonable assurance about whether  the  financial  statements are free  of material misstatement.  An
audit includes examining, on a test basis, evidence  supporting the amounts and disclosures  in the
financial statements. An audit also includes assessing the accounting  principles used  and significant
estimates made by management, as well as  evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable  basis for our opinion.

In our opinion, such consolidated financial  statements  present fairly, in  all  material  respects, the

financial position of the Company as of  October 1, 2016  and  October 3, 2015, and  the results of  its
operations and its cash flows for each  of  the  three years in the  period  ended October 1, 2016, in
conformity with accounting principles  generally  accepted in the United States of America.

We  have also audited, in accordance  with the standards of  the Public Company Accounting

Oversight Board (United States), the  Company’s  internal control over financial reporting as  of
October 1, 2016, based on the criteria established in Internal Control—Integrated Framework (2013)
issued by the Committee of Sponsoring  Organizations of the Treadway  Commission and our report
dated November 29, 2016 expressed an unqualified opinion on the Company’s internal control over
financial reporting.

Fiscal Year

Our fiscal year ends on the Saturday  closest to September 30. Fiscal years 2016,  2015 and 2014

ended on October 1, 2016, October 3,  2015  and September 27, 2014, respectively, and are referred to
in these financial statements as fiscal  2016, fiscal 2015,  and fiscal 2014 for  convenience. Fiscal years
2016 and 2014 include 52 weeks and fiscal year  2015 includes 53  weeks. The  fiscal years of the majority
of our international subsidiaries end  on September 30.  Accordingly, the  financial  statements  of these
subsidiaries as of that date and for the  years  then ended have  been used for our consolidated financial
statements. Management believes that the  impact  of  the use of  different  year-ends is immaterial to our
consolidated financial statements taken  as a whole.

Use of Estimates

The preparation of consolidated financial statements in conformity with Generally  Accepted
Accounting Principles (‘‘GAAP’’) requires  management to make estimates  and assumptions that affect
the reported amounts of assets and liabilities and disclosure  of contingent assets and  liabilities  at the
date  of  the consolidated financial statements  and  the reported amounts of revenues and expenses
during the reporting period. Actual results could differ  from those  estimates.

Basis of Presentation

The consolidated financial statements  include the accounts  of Coherent, Inc.  and its majority-
owned subsidiaries (collectively, the ‘‘Company’’, ‘‘we’’, ‘‘our’’, or  ‘‘Coherent’’). Intercompany  balances
and transactions have been eliminated.

Fair  Value of Financial Instruments

The carrying amounts of certain of our financial instruments  including  accounts receivable,

accounts payable and accrued liabilities approximate fair  value  due to their short maturities.  Short-term
investments are comprised of available-for-sale securities, which are carried at fair value. Other
non-current assets include trading securities and life insurance contracts  related  to  our deferred
compensation plans; trading securities  are  carried  at fair value  and life insurance contracts are  carried
at cash surrender values, which due to their ability to be converted  to  cash at that amount, approximate
their fair values. Foreign exchange contracts  are stated at  fair value based  on prevailing  financial
market information.

Cash Equivalents

All highly liquid investments with maturities of three  months or  less at the time of purchase are

classified as cash equivalents. At fiscal  2016 year-end, cash and cash equivalents included cash  and
money market funds.

Concentration of Credit Risk

Financial instruments that may potentially  subject us to concentrations of credit  risk consist

principally of cash equivalents, short-term investments  and accounts  receivable. At fiscal 2016 year-end,
the majority of our short-term investments were in  commercial paper and equity  securities. Cash
equivalents and short-term investments  are  maintained with several  financial institutions and may
exceed the amount of insurance provided  on such balances. At October  1, 2016, we held cash and  cash
equivalents and short-term investments  outside the U.S. in certain of our foreign  operations  totaling
approximately $331.0 million, $93.1 million of which  was  denominated in currencies  other  than the  U.S.
dollar. The majority of our accounts receivable  are derived from sales  to  customers  for commercial
applications. We perform ongoing credit  evaluations of our customers’  financial condition and  limit the
amount of credit extended when deemed necessary  but generally require no collateral. In certain
instances, we may require customers to issue a letter of credit. We maintain reserves  for potential
credit losses. Our products are broadly  distributed  and there  was one customer who accounted  for
18.0% and 21.4% of accounts receivable at fiscal 2016 and fiscal 2015  year-end. We had another
customer who accounted for 18.7% of  accounts receivable at fiscal 2016  year-end.

Derivative Financial Instruments

Our primary objective for holding derivative financial instruments is to manage  currency  exchange

rate risk. Principal currencies hedged  include the Euro, South Korean Won, Japanese Yen, British
Pound, Chinese Renminbi, Malaysian  Ringgit  and  Singapore dollar.  Our derivative financial instruments
are recorded at fair value, on a gross basis, and are included in  other  current assets and  other current
liabilities.

Our accounting policies for derivative financial  instruments are based on  whether they  meet the
criteria for designation as a cash flow hedge. Changes in  the fair  value of these cash flow hedges that
are highly effective are recorded in accumulated other comprehensive income and reclassified into
earnings in the same line item on the  consolidated  statements of operations as the  impact  of  the
hedged transaction during the period  in which  the hedged transaction affects earnings.  The ineffective
portion of cash flow hedges are recognized immediately in  other  income and  expenses. Derivatives that
we designate as cash flow hedges are classified in  the consolidated  statements of cash  flows  in the same
section as the underlying item, primarily within cash flows from operating activities.  The  changes in fair
value of derivative instruments that are  not  designated as  hedges  are recognized immediately in other
income (expense).

We  formally document all relationships between  hedging instruments and hedged  items,  as well as

the risk management objective and strategy for  undertaking various hedge  transactions. This  process
includes linking all derivatives that are designated as cash-flow hedges to specific forecasted
transactions. We also assess, both at  the hedge’s inception and on  an ongoing basis,  whether  the
derivatives that are used in hedging transactions  are highly effective in offsetting changes  in cash flows
of the hedged items.

Asset  Retirement Obligations

The fair value (the present value of estimated cash flows)  of a liability for an asset  retirement
obligation is recognized in the period  in which  it is  incurred if a reasonable estimate  of  fair value can
be made. The fair value of the liability  is  added to the carrying  amount  of  the associated asset  and this
additional carrying amount is depreciated over the life  of the asset. All of our existing asset  retirement
obligations are associated with commitments to return the  property to its  original  condition  upon lease
termination at various sites and costs to clean  up and dispose of certain fixed assets at  our Sunnyvale,
California site. We estimated that as of fiscal  2016 year-end, gross expected  future cash flows of
$3.1 million would be required to fulfill these  obligations.

The following table reconciles changes in  our  asset retirement liability for fiscal 2016  and 2015 (in

thousands):

At October 1, 2016 and October 3, 2015, the asset retirement  liability  is included in Other

long-term liabilities on our consolidated  balance sheets.

Long-lived Assets

We  evaluate the carrying value of long-lived assets, including intangible  assets, whenever events or

changes in business circumstances or our  planned use of long-lived assets indicate that their carrying
amounts may not be fully recoverable or  that their useful  lives  are  no  longer appropriate. Reviews are
performed to determine whether the carrying values of long-lived assets  are impaired based on a
comparison to the undiscounted expected  future net cash flows.  If the comparison indicates that
impairment exists, long-lived assets that are classified as held  and used are written down to their
respective fair values. When long-lived  assets are  classified as held  for sale, they are  written  down to
their respective fair values less costs to sell. Significant management judgment is required in  the
forecast of future operating results that is used in the preparation  of expected undiscounted  cash flows.
For fiscal years 2016, 2015 and 2014,  there were  no significant asset impairments recorded other than
the $2 million impairment of our investment in  SiOnyx in  fiscal 2015 (See Note  8. ‘‘Balance Sheet
Details’’).

Goodwill

Goodwill is tested for impairment on  an annual basis and between annual tests in certain
circumstances, and written down when impaired (see  Note  7. ‘‘Goodwill and Intangible  Assets’’). In

98

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

testing for impairment, we have the option  to  first assess  qualitative factors to determine  whether it  is
more likely than not (that is, a likelihood  of more  than 50%) that the fair value of a reporting  unit is
less  than its carrying amount. Moreover,  an entity can  bypass the qualitative assessment  for any
reporting unit in any period and proceed  directly  to  step  one  of  the impairment test, and then resume
performing the qualitative assessment in  any subsequent period.  In both our fiscal 2016 and 2015
annual testing, we performed a qualitative assessment of the goodwill for our SLS reporting unit using
the opening balance sheet as of the first day of the fourth quarter and  noted no  impairment. For  the
CLC reporting unit, we elected to bypass the qualitative assessment and proceed directly to performing
the first step of the goodwill impairment test. Accordingly, we performed our Step 1  test using the
opening balance sheet as of the first day of  the fourth  quarter and noted  no impairment in both fiscal
2016 and 2015. (See Note 7 for additional discussion of the fiscal 2016 analysis.)

Intangible Assets

Intangible assets, including acquired existing technology, customer lists  and  trade name are
amortized on a straight-line basis over  their estimated useful lives, currently 3  year to 15 years (See
Note 7. ‘‘Goodwill and Intangible Assets’’).

Warranty Reserves

We  provide warranties on the majority of our product  sales and reserves for estimated warranty
costs are recorded during the period of  sale. The determination of  such reserves  requires us to make
estimates of product return rates and  expected  costs to repair or replace the products under warranty.
We  currently establish warranty reserves based on historical  warranty costs for each product  line. The
weighted average warranty period covered is approximately  15 months. If actual  return  rates  and/or
repair and replacement costs differ significantly  from our estimates, adjustments to cost of  sales may  be
required in future periods.

Components of the reserve for warranty costs during fiscal 2016, 2015 and 2014 were as follows (in

Loss contingencies

We  are subject to the possibility of various loss  contingencies arising  in the ordinary course of
business. We consider the likelihood  of  loss or impairment  of  an asset, or the incurrence of a liability,
as well as our ability to reasonably estimate  the amount of loss, in determining loss contingencies. An

99

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

estimated loss contingency is accrued when  it is  probable that an asset has been  impaired  or a liability
has been incurred and the amount of  loss  can be reasonably estimated. If  we determine that a loss is
possible and the range of the loss can be reasonably determined,  then  we disclose the  range of the
possible loss. We regularly evaluate current information available to us  to determine whether an  accrual
is required, an accrual should be adjusted  or a range  of possible  loss should be disclosed.

Revenue Recognition

When a sales arrangement contains multiple elements, such as products and/or services, we
allocate revenue to each element based on  a selling  price hierarchy. Using the  selling price  hierarchy,
we determine the selling price of each deliverable using vendor specific objective evidence (‘‘VSOE’’),
if it  exists, and otherwise third-party  evidence (‘‘TPE’’). If neither VSOE nor TPE  of selling  price
exists, we use estimated selling price  (‘‘ESP’’).  We  generally  expect  that we will not be able to establish
TPE due to the nature of the markets in which we compete,  and, as such, we  typically will  determine
selling price using VSOE or if not available,  ESP.

Our basis for establishing VSOE of a deliverable’s selling price consists of standalone sales

transactions when the same or similar  product or service is sold separately. However,  when services are
never sold separately, such as product installation services, VSOE  is based on the product’s estimated
installation hours based on historical experience multiplied by  the standard service billing rate. In
determining VSOE, we require that a substantial majority of the selling price for a product or service
fall within a reasonably narrow price  range, as defined by us. We also consider  the geographies  in
which  the products or services are sold,  major product and service groups,  and other  environmental
variables in determining VSOE. Absent  the existence of  VSOE and TPE, our determination  of a
deliverable’s ESP involves evaluating several factors based on the specific facts  and circumstances  of
these arrangements, which include pricing  strategy and policies driven  by  geographies, market
conditions, competitive landscape, correlation between  proportionate selling price and list price
established by management having the  relevant authority,  and  other environmental variables in which
the deliverable is sold.

For multiple element arrangements which include extended maintenance contracts,  we allocate  and

defer the amount of consideration equal to the separately stated  price and  recognize revenue on a
straight-line basis over the contract period.

We  recognize revenue when all four  revenue recognition criteria  have been met: persuasive
evidence of an arrangement exists, the  product has  been delivered or  the  service  has been  rendered,
the price is fixed or determinable and collection is reasonably  assured. Revenue from  product sales is
recorded  when all of the foregoing conditions are  met and risk of loss and title passes  to  the customer.
Sales to customers are generally not subject  to  any  price protection  or  return rights.

The majority of our sales are made to original equipment manufacturers (‘‘OEMs’’), distributors,

representatives and end-users in the non-scientific market.  Sales  made to these customers do not
require installation of the products by  us and are not subject to other post-delivery obligations,  except
in occasional instances where we have  agreed to perform  installation  or provide training. In those
instances, we defer revenue related to  installation  services or training  until these  services have been
rendered. We allocate revenue from multiple element arrangements to the various  elements based upon
relative fair values.

100

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

Our sales to distributors, representatives and  end-user  customers typically  do not have customer
acceptance provisions and only certain  of  our  sales  to  OEM customers and  integrators have customer
acceptance provisions. Customer acceptance  is generally limited to performance under  our published
product  specifications. For the few product sales that have customer acceptance provisions because  of
higher  than published specifications, (1)  the products are tested  and  accepted by the customer at our
site or the customer accepts the results of our  testing program prior  to  shipment to the customer, or
(2) the revenue is deferred until customer  acceptance  occurs.

Sales to end-users in the scientific market typically  require installation and, thus, involve
post-delivery obligations; however, our  post-delivery  installation  obligations are not essential to the
functionality of our products. We defer  revenue related  to installation  services until completion of these
services.

For most products, training is not provided; therefore,  no post-delivery training  obligation exists.

However, when training is provided to  our customers,  it is typically priced separately and  is recognized
as revenue as these services are provided.

We  record taxes collected on revenue-producing  activities on a net basis.

Research and Development

Research and development expenses include salaries, contractor and consultant fees, supplies and
materials, as well as costs related to other overhead  such as  depreciation, facilities, utilities  and other
departmental expenses. The costs we  incur with respect  to internally  developed  technology and
engineering services are included in research and development expenses as incurred as they do not
directly relate to any particular licensee, license agreement or license fee.

We  treat third party and government  funding of our research and development activity, where  we
are the primary beneficiary of such work conducted, as  a reduction  of research and  development cost.
Research and development reimbursements of $2.7  million,  $2.5 million and  $7.2 million were  offset
against research and development costs in fiscal  2016, 2015 and 2014,  respectively.

Foreign Currency Translation

The functional currencies of our foreign subsidiaries are generally their respective local  currencies.
Accordingly, gains and losses from the  translation of the financial statements  of the foreign subsidiaries
are reported as a separate component of accumulated other comprehensive income (‘‘OCI’’).  Foreign
currency transaction gains and losses  are  included  in earnings.

Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the  change in equity of a business enterprise during a

period from transactions and other events and circumstances from non-owner sources. Accumulated
other comprehensive income (loss) (net  of tax) at fiscal 2016 year-end is  substantially comprised  of
accumulated translation adjustments  of  $(8.6) million and unrealized gain on  marketable equity
securities of $3.3 million. Accumulated  other  comprehensive income (loss) (net of tax) at fiscal
2015 year-end is substantially comprised  of accumulated  translation  adjustments of $(10.4)  million.

Earnings Per Share

Basic earnings per share is computed based on the weighted average number  of  shares outstanding
during the period, excluding unvested  restricted stock. Diluted  earnings per share  is computed based  on
the weighted average number of shares outstanding during  the period increased by the  effect of dilutive
employee stock awards, including stock  options, restricted  stock awards and  stock  purchase  contracts,
using the treasury  stock method.

Stock-Based Compensation

We  account for stock-based compensation using the  fair value of the  awards granted. We  value
restricted stock units using the intrinsic  value method, which is based  on the  fair market value  price on
the grant date. We use a Monte Carlo  simulation  model to estimate the fair  value of  performance
restricted stock units. We use historical  data  to  estimate pre-vesting option and restricted stock unit
forfeitures and record stock-based compensation expense only  for those  awards that are expected to
vest. We amortize the fair value of stock  awards on  a straight-line basis over the requisite service
periods of the awards, which are generally the  vesting  periods. See Note 12 ‘‘Employee Stock  Award,
Option and Benefit Plans’’ for a description of our stock-based employee compensation plans and the
assumptions we use to calculate the fair value  of  stock-based employee compensation.

Shipping and Handling Costs

We  record costs related to shipping and  handling  of  net sales  in cost of sales for  all  periods

presented. Shipping and handling fees  billed to customers  are included in net sales. Custom duties
billed to customers are recorded in cost  of sales.

Income Taxes

As part of the process of preparing our  consolidated financial statements,  we are  required to
estimate our income tax provision (benefit)  in each of the  jurisdictions  in which we operate. This
process involves us estimating our current income tax provision (benefit)  together  with assessing
temporary differences resulting from  differing treatment of items  for tax  and accounting  purposes.

102

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

These differences result in deferred tax assets  and  liabilities, which are  included within our consolidated
balance sheets.

We  account for uncertain tax issues pursuant to ASC  740-10 Income Taxes, which creates a single

model to address accounting for uncertainty in  tax positions by prescribing a  minimum recognition
threshold that a tax position is required to meet before being recognized  in the financial statements.
This standard provides a two-step approach  for  evaluating tax positions. The  first  step,  recognition,
occurs when a company concludes (based  solely on the technical  aspects of the matter)  that  a tax
position is more likely than not to be sustained upon examination by  a taxing authority. The second
step, measurement, is only considered  after  step one has been satisfied and measures  any tax benefit at
the largest amount that is deemed more  likely  than not to be realized upon ultimate settlement of the
uncertainty. These determinations involve  significant judgment  by management. Tax positions that fail
to qualify for initial recognition are recognized in the  first  subsequent interim period that they meet the
more likely than not standard or when  they are resolved through  negotiation  or litigation with  factual
interpretation, judgment and certainty.  Tax laws and regulations themselves are  complex and are subject
to change as a result of changes in fiscal  policy, changes in  legislation, evolution  of regulations and
court filings. Therefore, the actual liability for U.S. or foreign  taxes may be materially different from
our  estimates, which could result in the  need to record additional  tax  liabilities or potentially  to  reverse
previously recorded tax liabilities.

We  record a valuation allowance to reduce our deferred  tax assets  to  an amount that more likely

than not will be realized. While we have  considered future  taxable income and  ongoing prudent and
feasible tax planning strategies in assessing the  need  for the  valuation  allowance,  in the event we were
to determine that we would be able to realize our deferred tax assets  in the future in excess of  our net
recorded  amount, an adjustment to the  allowance  for  the deferred tax asset  would increase income in
the period such determination was made. Likewise, should we determine that we  would not be able to
realize all or part of our net deferred tax asset in the future, an adjustment to the allowance for the
deferred tax asset would be charged  to  income in the  period  such determination  was made.

Federal and state income taxes have not been provided on  a portion of the unremitted earnings of
foreign subsidiaries because such earnings are intended  to  be  permanently reinvested. The total amount
of unremitted earnings (including accumulated translation adjustments) of foreign subsidiaries for which
we have not yet recorded federal and  state income taxes was approximately $574.0  million  and
$471.9 million at fiscal 2016 and 2015  year-end, respectively.  The  amount  of federal  and state income
taxes that would be payable upon repatriation of  such earnings is not practicably determinable.  We
have not, nor do we anticipate the need to, repatriate funds  to  the United States  to  satisfy domestic
liquidity needs arising in the ordinary  course of business.

Adoption of New Accounting Pronouncements

In November 2015, the FASB issued amended guidance that clarifies that  in a classified  statement

of financial position, an entity shall classify deferred  tax  liabilities  and assets as noncurrent amounts.
The new guidance supersedes ASC 740-10-45-5 which required  the valuation allowance  for a  particular
tax jurisdiction be allocated between  current and noncurrent deferred tax assets for  that  tax jurisdiction
on a pro rata basis. We elected to early adopt the  standard retrospectively in the  first  quarter  of  fiscal
2016, which resulted in the reclassification of $28.1 million from current deferred income tax assets to

103

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

non-current deferred income tax assets and non-current  deferred income tax liabilities as  of  October 3,
2015.

In April 2015, the FASB issued amended guidance that simplifies the  presentation of debt issuance

costs by requiring that debt issuance costs related to a recognized debt liability be presented in the
balance sheet as a direct deduction from  the carrying  amount  of that  debt  liability,  consistent with  debt
discounts. The recognition and measurement  guidance for  debt issuance costs are not affected by the
amended guidance. The new standard  will  become effective  for our fiscal year beginning October 2,
2016. We elected to early adopt the standard in the  second quarter  of fiscal 2016  and have  recorded
the debt issuance costs of $5.2 million  as  of October 1, 2016 in other  assets for  the debt  commitment
we entered into in the second quarter of fiscal 2016. The  debt  issuance cost related to the  term loan
facility will be reclassified to debt in the first quarter  of  fiscal  2017.

Recently Issued Accounting Pronouncements

In October 2016, the FASB issued amended guidance  that  improves the accounting  for the  income

tax consequences of intra-entity transfers of  assets other than inventory. Under the new guidance, an
entity should recognize the income tax consequences  of  an intra-entity  transfer of an asset  other than
inventory when the transfer occurs. The  new  standard will become  effective for  our fiscal  year
beginning October 1, 2018. We are currently assessing the impact of this amended guidance and the
timing of  adoption.

In May 2016, accounting guidance was issued  to  clarify  the not yet effective revenue  recognition

guidance issued in May 2014. This additional guidance does not change the core  principle of the
revenue recognition guidance issued in  May 2014, rather, it provides clarification  of  accounting for
collections of sales taxes as well as recognition of  revenue (i) associated  with contract  modifications,
(ii) for noncash consideration, and (iii)  based  on the  collectability of the consideration from the
customer. The guidance also specifies when a contract should be considered ‘‘completed’’ for purposes
of applying the transition guidance. The effective date and transition requirements for  this  guidance are
the same as the effective date and transition requirements for  the  guidance previously issued in 2014,
which  is effective for our fiscal year beginning September 30,  2018. We  are currently  evaluating  the new
guidance and have not determined the  impact this  standard may have on our financial statements nor
have we decided upon the method of adoption.

In March 2016, the FASB issued amended  guidance that simplifies several  aspects of the

accounting for employee share-based  payment transactions, including the  accounting for  income  taxes,
forfeitures, and statutory tax withholding  requirements,  as well  as classification in the  statement  of cash
flows. Under the new guidance, an entity recognizes  all  excess  tax  benefits and tax  deficiencies as
income tax expense or benefit in the income  statement. This change eliminates  the notion of the APIC
pool and significantly reduces the complexity  and  cost of accounting for excess tax benefits  and tax
deficiencies. The new standard will become effective for our fiscal year beginning October  1, 2017. We
are currently assessing the impact of this  amended guidance and the  timing of adoption.

In February 2016, the FASB issued amended  guidance to increase  transparency and comparability

among organizations by recognizing lease assets  and  lease  liabilities  on  the balance sheet  and disclosing
key information about leasing arrangements.  The  new guidance  clarifies the criteria for distinguishing
between a finance lease and operating lease,  as well  as classification between the two types  of  leases,
which  is substantially unchanged from the  previous lease guidance.  Further,  the new guidance  requires

104

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

a lessee to recognize in the statement of financial position a  liability  to  make lease payments (the lease
liability) and a right-of-use asset, initially  measured at the present value of the lease  payments. For
finance leases, a lessee should recognize interest on the  lease liability separately from amortization of
the right-of-use asset. For operating leases, a lessee should recognize a  single lease cost, calculated  so
that the cost of the lease is allocated over  the lease  term on  a  generally straight-line basis.  For leases
with a term of 12 months or less, a lessee  is permitted to make an accounting policy  election not to
recognize lease assets and lease liabilities. The new  standard will become effective for our fiscal year
beginning September 29, 2019. We are  currently assessing the impact  of  this amended guidance and the
timing of  adoption.

In January 2016, the FASB issued amended guidance that  revises the recognition and measurement

of financial instruments. The new guidance  requires equity investments (except those  accounted for
under the equity method of accounting, or those that result in consolidation of the  investee) to be
measured at fair value with changes  in fair value recognized in net income, requires  public  business
entities to use the exit price notion when  measuring the  fair value of financial instruments for
disclosure purposes, requires separate  presentation of financial assets  and  financial  liabilities  by
measurement category and form of financial asset, and  eliminates the requirement  for public business
entities to disclose the method(s) and significant  assumptions used to estimate the fair value that is
required to be disclosed for financial instruments measured at amortized cost. The new  standard will
become  effective for our fiscal year beginning September 30, 2018.  We  are currently assessing the
impact of this amended guidance and the  timing of adoption.

The purchase price allocated to goodwill was finalized  in the first quarter of fiscal  2016, with an
increase of $0.4 million and a corresponding decrease of $0.4 million  to  tangible  assets, and has been
updated from the preliminary allocation in the  fourth quarter  of fiscal 2015.

Results of operations for the business  have been included in our  consolidated financial statements

subsequent to the date of acquisition  and pro forma results of operations  in accordance with
authoritative guidance for prior periods have not been presented because the effect  of  the acquisition
was not material to our prior period  consolidated financial results.

The identifiable intangible assets are  being  amortized over  their respective useful lives of three to

five years.

None of the goodwill from this purchase  is deductible for  tax purposes.

We  expensed $0.1 million of acquisition-related  costs as selling, general and  administrative

expenses in our consolidated statements  of  operations for  our fiscal year  2015.

Tinsley Optics

On July 27, 2015, we acquired the assets  and  certain liabilities of the Tinsley Optics (‘‘Tinsley’’)

business from L-3 Communications Corporation for approximately $4.3 million, excluding transaction
costs. Tinsley is a specialized manufacturer  of high precision optical  components and  subsystems sold
primarily in the aerospace and defense industry. Tinsley manufactures the large form  factor optics for
our  excimer laser annealing systems. Tinsley has been included in our Specialty Lasers and Systems

The purchase price was lower than the fair value of net  assets purchased,  resulting in a  gain of
$1.3 million recorded as a separate line item in our consolidated statements of  operations for our fiscal
year 2015. The Company reassessed the  recognition and  measurement of  identifiable assets acquired
and liabilities assumed and concluded  that all acquired assets and assumed  liabilities were  recognized
and that the valuation procedures and resulting measures were  appropriate.

Results of operations for the business  have been included in our  consolidated financial statements

4. FAIR VALUES

We  measure our cash equivalents and marketable securities  at fair value. The  fair values of our

financial assets and liabilities are determined  using quoted market prices of identical assets or  quoted
market prices of similar assets from active markets.  We recognize transfers between  levels within the
fair value hierarchy, if any, at the end  of  each quarter.  There  were no transfers  between levels  during
the periods presented. As of October 1,  2016 and October  3, 2015, we did not have any assets  or
liabilities valued based on Level 3 valuations.

Financial assets and liabilities measured at  fair value as  of  October 1, 2016 and October  3, 2015

used to value these instruments generally consist  of  market yields,  reported  trades, broker/dealer quotes  or
alternative pricing sources with reasonable  levels  of  price transparency. Pricing sources include  industry
standard data providers, security master files  from large financial  institutions,  and  other  third  party  sources

which are input into a distribution-curve-based  algorithm  to  determine  a daily  market  value.  This creates  a
‘‘consensus price’’  or a  weighted average price  for each  security.

(3) The principal market in which we execute  our foreign  currency  contracts is  the  institutional market  in an

over-the-counter environment with a relatively  high  level  of price  transparency. The  market participants
usually are large  commercial banks. Our foreign  currency  contracts’ valuation  inputs  are  based  on quoted
prices and quoted pricing intervals from public  data sources  and do  not  involve  management judgment.  At
October 1, 2016, prepaid expenses and other assets include  $889 non-designated forward  contracts;  other
current liabilities include $3,100 non-designated  forward  contracts.  At  October 3,  2015, prepaid  expenses  and
other assets include $217 non-designated  forward contracts  and $41  foreign  currency  contracts designated for
cash flow hedges, respectively; other current  liabilities include  $239  non-designated  forward contracts  and  $0
foreign currency contracts designated for cash flow hedges,  respectively. See  Note 6,  ‘‘Derivative  Instruments
and Hedging Activities’’.

(4) The fair value of mutual funds is determined  based  on quoted  market  prices. Securities traded  on  a  national

exchange are stated at the last reported sales  price on  the day  of valuation;  other  securities traded in
over-the-counter markets and listed securities  for which  no sale was  reported  on that date  are stated as  the
last quoted bid price.

5. SHORT-TERM INVESTMENTS

We  consider all highly liquid investments with  maturities of three months or  less  at the time of

purchase to be cash equivalents. Investments classified as  available-for-sale are reported  at fair  value
with unrealized gains and losses, net  of related income taxes, recorded  as a  separate component of  OCI
in stockholders’ equity until realized.  Interest and  amortization of premiums and  discounts for debt
securities are included in interest income. Gains and losses on  securities sold are  determined based  on
the specific identification method and  are  included in  other  income  (expense).

6. DERIVATIVE INSTRUMENTS AND  HEDGING  ACTIVITIES

We  maintain operations in various countries outside of the United States and have foreign

subsidiaries that manufacture and sell our products in various global  markets. The  majority of our sales
are transacted in U.S. dollars. However, we do generate revenues in  other  currencies, primarily  the
Euro,  Japanese Yen, South Korean Won  and Chinese Renminbi (RMB). As a  result, our earnings,  cash
flows and cash balances are exposed to fluctuations in foreign  currency exchange  rates. We  attempt to
limit these exposures through financial  market  instruments.  We utilize derivative  instruments, primarily
forward contracts with maturities of seven months or less, to manage  our exposure associated with

109

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

6. DERIVATIVE INSTRUMENTS AND  HEDGING  ACTIVITIES (Continued)

anticipated cash flows and net asset and  liability positions denominated in foreign currencies. Gains  and
losses on the  forward contracts are mitigated by gains and  losses  on the underlying instruments. We do
not use derivative financial instruments for  speculative or trading purposes. The credit risk  amounts
represent the Company’s gross exposure  to  potential accounting loss on derivative instruments that are
outstanding or unsettled if all counterparties  failed to perform  according to the terms  of  the contract,
based on then-current currency rates at each respective date.

For derivative instruments that are not  designated as hedging instruments, gains and losses are

recognized in other income (expense).

On August 1, 2016, we purchased forward contracts totaling 670.0 million Euros, with a value date

of November 30, 2016, to limit our foreign  exchange  risk related to the commitment of our term loan
(denominated in Euros) in an amount  of the Euro equivalent of $750.0 million to finance the U.S.
dollar payment for the acquisition of  Rofin. As of October  1, 2016, we had recognized  an unrealized
loss of $2.2 million on these contracts  in  other  income  (expense)  net. Subsequent  to  October 1,  2016,
we settled these hedges at a net gain  of $3.1  million,  resulting in a realized  gain of $5.3 million in  the
first quarter of fiscal 2017.

are evaluated for effectiveness quarterly. The  effective portion of the gain or loss on these  hedges  is
reported as a component of OCI in stockholder’s  equity and is reclassified  into  earnings when  the
underlying transaction affects earnings. We had no  cash flow hedges outstanding  at October 1, 2016.
Changes in the fair value of currency forward contracts due to changes in  time value are  excluded from
the assessment of effectiveness and recognized in  other  income (expense)  as incurred.  We classify  the
cash flows from the foreign exchange  forward contracts  that  are  accounted  for as cash  flow hedges in
the same section as the underlying item, primarily  within cash flows from operating  activities since we
do not designate our cash flow hedges  as investing or financing activities.

We  had entered into certain derivative forward  contracts  to sell  Japanese Yen  and buy Euro to
hedge revenue exposures related to our  photonics-based solutions  in Asia. In order to facilitate the
hedge, we transacted with counterparties in the U.S.  directly and then allocated the  hedge contracts to
our  affiliates through a back-to-back relationship with  our German subsidiary. The German subsidiary
designated these hedge contracts as cash  flow hedges under ASC 815.  The  hedges  were settled prior to
October 1, 2016

The fair value of our derivative instruments is  included in prepaid expenses  and other  assets and in

other current liabilities in our Consolidated  Balance Sheets (See Note  4); such amounts were not

During  the fiscal year ended October 1, 2016 and October  3, 2015, we  recognized losses of $31,000

and $107,000, respectively, in other income (expense)  as ineffectiveness related to a portion  of an
anticipated hedged transaction that failed to occur within  the original hedge period plus  two months.
The remainder of the hedged transaction  occurred as  expected  and effective amounts were recognized
in revenue or cost of sales as disclosed  in the  above table.

The amounts that will be reclassified  from OCI to earnings are generally offset by the recognition
of the hedged transactions (e.g., anticipated  cost of sales) in earnings,  thereby achieving the realization
of prices contemplated by the underlying risk  management strategies  and  will vary from  the expected
amounts presented above as a result  of  changes in foreign exchange rates.

To mitigate credit risk in derivative transactions, we  enter into  master netting  arrangements that

allow each counterparty in the arrangements to net settle amounts of multiple and separate derivative
transactions under certain conditions.  We  present the fair value  of  derivative assets and  liabilities within
the our consolidated balance sheet on a gross  basis even when derivative transactions  are subject to
master netting arrangements and may otherwise qualify for  net  presentation. Our derivative  contracts
do not contain any credit risk related contingent features  and  do not require collateral or other security
to be furnished by us or the counterparties.

7. GOODWILL AND INTANGIBLE ASSETS

Goodwill is tested for impairment on  an annual  basis and between annual tests if events or
circumstances indicate that an impairment loss may have  occurred, and we write down these assets
when impaired. We perform our annual impairment  tests during  the fourth  quarter  of each fiscal year
using the opening balance sheet as of  the first  day  of the fourth quarter, with  any resulting impairment
recorded  in the fourth quarter of the  fiscal year.

During  fiscal 2016, Coherent had two  reporting units: Specialty Laser  Systems (‘‘SLS’’)  and

Commercial Lasers and Components (‘‘CLC’’). In  our fiscal 2016 annual testing, we performed a
qualitative assessment of the goodwill for our  SLS reporting unit  during the fourth quarter of fiscal
2016 using the opening balance sheet  as of  the first day of the  fourth quarter and concluded  that  it was
more likely than not that the fair value  of the  reporting unit exceeded its carrying amount. In assessing
the qualitative factors, we considered the  impact  of  these  key factors:  macroeconomic conditions,
fluctuations in foreign currency, market  and  industry conditions, our operating and competitive

113

environment, regulatory and political developments, the overall financial performance of the reporting
unit including cost factors and budgeted-to-actual revenue results. We also considered our market
capitalization, stock price performance and the  significant excess between  the estimated fair value and
carrying  value of the SLS reporting unit. Based  on our assessment,  goodwill in the SLS reporting  unit
was not impaired as of the first day of the fourth quarter of fiscal 2016. As such, it was not necessary
to perform the two-step goodwill impairment test at that time. For the  CLC reporting unit,  we elected
to bypass the qualitative assessment and proceed  directly  to performing  the first step of the goodwill
impairment test. We performed our Step  1 test using the  opening balance sheet as  of the first day of
the fourth quarter and noted no impairment.  We determined  the  fair value of the CLC  reporting unit
for the Step 1 test using a 50-50% weighting  of the Income (discounted cash  flow) approach and
Market (market comparable) approach.  Management completed  and reviewed  the results of  the Step 1
analysis and concluded that a Step 2  analysis was not required as the  estimated  fair value of the CLC
reporting unit was  significantly in excess  of its carrying  value. Between the  completion  of that testing
and the end of the fourth quarter of  fiscal 2016, we noted no  indications of  impairment or triggering
events with either  reporting unit to cause us to review goodwill for potential impairment.

(1) Gross amount of goodwill for our  CLC segment was  $25.7  million  at both  October 1,

2016 and October 3, 2015. At both October  1, 2016 and October 3,  2015, the accumulated
impairment loss for the CLC reporting unit  was $19.3 million reflecting an  impairment
charge in fiscal 2009.

(2) Gross amount of goodwill for our  SLS segment was $97.4 million  and $97.8 million  at

October 1, 2016 and October 3, 2015. At  both  October 1, 2016 and October  3, 2015, the
accumulated impairment loss for the  SLS  reporting unit was $2.4 million reflecting an
impairment charge in fiscal 2003.

We  evaluate long-lived assets and amortizable intangible  assets whenever events or  changes in

business circumstances or our planned  use of assets  indicate  that their carrying amounts may  not  be
fully recoverable or that their useful  lives are no longer  appropriate. Reviews are  performed  to
determine whether the carrying values of assets are  impaired based on comparison to the  undiscounted
expected future cash flows identifiable to such long-lived and amortizable intangible assets. If the
comparison indicates that impairment exists, the  impaired asset is written down to its fair  value.

For accounting purposes, when an intangible asset is  fully amortized, it is removed from the

disclosure schedule.

Amortizable intangible assets include intangible assets acquired through  business  combinations as

well as through direct purchases or licenses.

The weighted average remaining amortization period for existing technology is approximately
2.1 years, the weighted average remaining  amortization period for customer lists is  2.8 years, and  the
weighted average remaining amortization period for trade name is  3.1 years. Amortization  expense for
intangible assets during fiscal years 2016, 2015, and 2014  was  $8.5 million, $8.2 million and $9.6 million,
respectively, which includes $6.0 million, $6.3 million  and  $7.5  million,  respectively, for amortization of
existing technology. The change in accumulated amortization  also includes $0.4 million  and $2.9 million
of foreign exchange impact for fiscal  2016 and fiscal 2015, respectively.

In fiscal  2010, we invested $2.0 million in SiOnyx, Inc., a privately-held company. The  investment

was included in other assets and was being carried on a cost basis.  During the  third  quarter  of  fiscal
2015 we determined that our investment became  other-than temporarily impaired. As a  result, during
the third quarter of fiscal 2015, we recorded  a non-cash  charge  of $2.0 million in our results of
operations to impair this investment.  In  determining the fair value of the cost  method investment, we
considered many factors including but not limited to operating performance  of the investee, the amount
of cash that the investee has on-hand, the ability  to  obtain  additional  financing  and the  overall market
conditions in which the investee operates. The  fair value of the cost  method investment  represents a
Level 3 valuation as the assumptions  used  in valuing the  investment were not directly or indirectly
observable.

For our $750.0 million debt financing commitment  with certain lenders  (See Note 9 ‘‘Borrowings’’),

we paid $5.2 million of debt issuance  costs in  fiscal 2016 and recorded it to other assets.  The debt
issuance cost related to the term loan facility will  be  reclassified to debt in the  first  quarter  of  fiscal
2017.

9. BORROWINGS

We  have several lines of credit which allow us  to  borrow  in the applicable local currency. We have
a total of $13.2 million of unsecured  foreign lines of credit as  of October 1, 2016. At October  1, 2016,
we had used $1.6 million of these available  foreign lines  of credit  as guarantees. These credit  facilities
were used in Europe and Japan during  fiscal 2016. In addition, our domestic line  of  credit consists of a
$50.0 million unsecured revolving credit  account. The agreement will  expire on  May 31,  2017. The line
of credit is subject to covenants related to financial  ratios and tangible net  worth with  which we  are
currently in compliance. We have an outstanding  balance  of  $20.0 million and have used $1.1  million
for letters of credit against our domestic  line  of  credit  as of October 1, 2016.  On November 4, 2016, we
repaid the outstanding balance, plus  accrued  interest, on our domestic line  of  credit and terminated the
credit facility.

On November 7, 2016, we entered into a  Credit Agreement (the ‘‘Credit Agreement’’) with

Barclays  Bank PLC (‘‘Barclays’’), Bank of America,  N.A. (‘‘BAML’’) and The Bank of Tokyo-
Mitsubishi UFJ, Ltd. (‘‘MUFG’’). The  Credit Agreement  provided for a 670.0 million  Euro  senior
secured term loan facility (the ‘‘Euro Term  Loan’’) and  a $100.0 million senior secured revolving credit
facility. On November 7, 2016, the Euro  Term Loan was drawn in full and its proceeds  were used to
finance the acquisition of Rofin and  pay  related fees and expenses. Also,  on November 7, 2016,  we
used 10.0 million Euro of the capacity  under the revolving credit facility for the issuance of a letter of
credit. We paid $5.2 million of debt issuance costs in fiscal  2016 and recorded it  to  other  assets on our

consolidated balance sheets as we had not drawn  down  the debt as of October 1, 2016.  The debt
issuance cost related to the term loan facility will  be  reclassified to debt in the  first  quarter  of  fiscal
2017. In the fourth quarter of fiscal 2016,  we  recorded an interest charge of $1.1  million interest
expense within other income (expense)  in our consolidated statement of operations related to the debt
financing commitment. See Note 16, ‘‘Subsequent Events’’ for  further discussion of the  issuance  of  the
financing.

As of October 1, 2016, we had total purchase  commitments for inventory of  approximately

Contingencies

We  are subject to legal claims and litigation arising  in the ordinary course of business, such as
product  liability, employment or intellectual property claims, including, but not limited  to,  the matters
described below. On May 14, 2013, IMRA America (‘‘Imra’’)  filed a complaint for  patent  infringement
against two of our subsidiaries in the Regional Court of D¨usseldorf, Germany, captioned In re IMRA
America Inc. versus Coherent Kaiserslautern  GmbH et.  al. 4b O 38/13. The complaint alleges  that  the
use of certain of the Company’s lasers infringes upon EP Patent No. 754,103,  entitled ‘‘Method For
Controlling Configuration of Laser Induced  Breakdown  and  Ablation,’’ issued November 5,  1997. The
patent, now expired in all jurisdictions, is owned  by the University of Michigan and licensed to Imra.
The complaint seeks unspecified compensatory  damages, the cost of court proceedings and seeks to
permanently enjoin the Company from infringing the patent in the future. Following the filing of the
infringement suit, our subsidiaries filed  a  separate nullity action with the Federal  Patent  Court in

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

10. COMMITMENTS AND CONTINGENCIES (Continued)

Munich, Germany requesting that the  court  hold that  the Patent was invalid based on prior art. On
October 1, 2015, the Federal Patent Court ruled  that the German portion of the  Patent was invalid.
Imra has appealed this decision to the  Federal  Court  of  Justice, the  highest civil jurisdiction court in
Germany. The infringement action is  currently  stayed pending the  outcome of such  appeal.
Management has made an accrual with respect to this matter  and has determined, based on its current
knowledge, that the amount or range  of reasonably  possible  losses  in excess of the amounts  already
accrued is not reasonably estimable.  Although we do not expect  that such legal claims and litigation
will ultimately have a material adverse  effect on our consolidated financial position, results of
operations or cash flows, an adverse  result in one or more matters could negatively  affect our results  in
the period in which they occur.

The United States and many foreign  governments  impose tariffs  and duties  on the import and
export of certain products we sell. From  time to time our duty calculations and payments are audited
by government agencies. During the  second quarter  of  fiscal  2016, we concluded an  audit in  South
Korea for customs duties and value added tax for the period  March 2009  to  March 2014. We paid
$1.6 million related to this matter in the second quarter of fiscal  2016 and  have no remaining accrual at
October 1, 2016.

On November 7, 2016, we entered into a  Credit Agreement with Barclays, BAML  and MUFG. See

Note 9 ‘‘Borrowings’’ and Note 16 ‘‘Subsequent Events’’ for  further discussion of the issuance of  the
financing.

In relation to the acquisition of Rofin, we  paid Barclays,  our financial advisor, a fee of

approximately $9.5 million, $1.0 million of which  was  paid upon  delivery of the fairness  opinion in the
second  quarter of fiscal 2016, and was recorded in the selling, general and administrative line of the
consolidated statements of operations, and the remaining portion of which was paid upon
consummation of the acquisition in the  first quarter of  fiscal 2017. We also paid Barclays,  BAML and
MUFG together approximately $17.0 million and $5.6 million for underwriting and upfront fees,
respectively, upon the close of the financing  on November 7, 2016.

11. STOCK REPURCHASES

On July 25, 2014, our Board of Directors authorized  a buyback  program whereby we  were

authorized to repurchase up to $25.0  million of our  common  stock from time to time  through July  31,
2015. During the first and second quarters of  fiscal  2015, we repurchased  and retired 434,114 shares of
outstanding common stock under this  plan  at an  average price  of $57.59 per share  for a  total  of
$25.0 million.

On January 21, 2015, our Board of Directors  authorized an  additional  stock repurchase  program to

repurchase up to $25.0 million of our  outstanding common stock from time to time through
January 31, 2016. During the fourth quarter of fiscal 2015,  we repurchased and retired 430,675 shares
of outstanding common stock under this  plan at an average price of $58.05 per share for  a total of
$25.0 million.

On August 25, 2015, our Board of Directors  authorized an  additional  stock repurchase  program to
repurchase up to $25.0 million of our  outstanding common stock from time to time through August  31,
2016. During the fourth quarter of fiscal  2015, we  repurchased  and retired  437,534 shares  of

Deferred Compensation Plans

Under our deferred compensation plans (‘‘plans’’), eligible employees  are permitted to make

compensation deferrals up to established  limits set under the plans and accrue  income  on these
deferrals based on reference to changes  in  available investment options.  While not required  by  the
plan,  the Company chooses to invest in insurance contracts and mutual funds in order to approximate
the changes in the liability to the employees. These investments and the liability to the employees  were

Coherent Employee Retirement and Investment Plan

Under the Coherent Employee Retirement and  Investment  Plan,  we match employee contributions

to the plan up to a maximum of 4% of  the employee’s individual earnings subject to IRS limitations.
Employees become eligible for participation on their first day of employment and for  Company
matching contributions after completing one year of service. Effective November  1, 2016, employees
became eligible for participation and Company matching contributions  on their first day of
employment. The Company’s contributions (net  of  forfeitures) during fiscal 2016, 2015,  and 2014 were
$4.1 million, $3.6 million and $3.6 million, respectively.

Employee Stock Purchase Plan

We  have an Employee Stock Purchase Plan (‘‘ESPP’’) whereby eligible  employees may  authorize

payroll  deductions of up to 10% of their  regular base salary to purchase shares at  the lower of 85%  of
the fair market value of the common  stock on the date  of commencement  of  the offering  or on  the last
day of the six-month offering period. During fiscal 2016, 2015  and 2014, a total of 141,340 shares,
132,004 shares and 134,321 shares, respectively, were purchased by and distributed to employees at  an
average price of $46.81, $51.34 and $48.68 per share, respectively. At  fiscal 2016 year-end, we  had
520,560 shares of our common stock  reserved  for future issuance under  the plan.

Stock Award Plans

We  maintain a stock plan for which employees, service providers and non-employee  directors are

eligible participants. This plan, the 2011 Equity  Incentive Plan (the ‘‘2011 Plan’’),  provides for grants of
options, time-based restricted stock units  and  performance  restricted stock units.  In prior years, we had
a stock  plan for which employees and service providers were eligible  participants  and a  non-employee
Directors’ Stock Option Plan for which only  non-employee directors  were  eligible participants. Those
prior plans have expired. Under the 2011  Plan,  Coherent may grant  options and awards (time-based
restricted stock units and performance  restricted  stock  units) to purchase up to 6,747,691  shares of
common stock, of which 5,230,398 shares  remained available for  grant at fiscal 2016  year-end.

Historically option grants to employees generally expired four  years  from the original grant  date.

Since adoption of the 2011 Plan, no stock options have been granted to employees.

Director options were previously automatically  granted to our non-employee directors. New
directors now initially receive an award  of  restricted stock  units  of 3,500 shares which  vest over  a two
year period. The annual grant for non-employee directors is 3,500 shares  of restricted  stock  units that
vest on February 15 of the calendar year  following the  grant.

Restricted stock awards and restricted  stock units are typically subject to  vesting restrictions—
either time-based or market-based conditions for  vesting.  Until restricted  stock  vests,  shares (including
those issuable upon vesting of the applicable restricted stock  unit) are subject to forfeiture if
employment or service to the Company  terminates prior to the  release of restrictions and  cannot be
transferred.

(cid:127) The service based restricted stock awards generally vest within  three years from the  date of

grant.

121

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

12. EMPLOYEE STOCK AWARD AND  BENEFIT PLANS  (Continued)

(cid:127) The service based restricted stock unit awards are generally subject to annual vesting over three

years from the date of grant.

(cid:127) The performance restricted stock unit award grants are generally  either subject  to  annual vesting
over three years from the date of grant or subject to a single vest measurement  three years from
the date of grant, depending upon achievement of performance measurements based on the
performance of the Company’s total shareholder returns (as defined in  the plan) compared  with
the performance of the Russell 2000  Index.

Fair  Value of Stock Compensation

We  recognize compensation expense  for all share-based payment awards based  on the fair value of
such awards. The expense is recognized on a straight-line basis per tranche over the  respective requisite
service period of the awards.

Determining Fair Value

Valuation and amortization method—We estimate the fair value of employee stock purchase shares

using the Black-Scholes-Merton option-pricing formula.  This  fair value is then  amortized on a
straight-line basis over the purchase period.

Expected  Term—The expected term represents the period of our employee stock purchase  plan.

Expected Volatility—Our process for computing expected volatility considers both  historical volatility
and market-based implied volatility; however our estimate of expected  forfeitures is based on historical
employee data and could differ from  actual  forfeitures.

Risk-Free Interest Rate—The risk-free interest rate used in the Black-Scholes-Merton valuation
method is based on the implied yield currently available on  U.S. Treasury zero-coupon issues with an
equivalent remaining term.

The fair values of shares purchased under  the employee stock  purchase plan  for fiscal 2016, 2015

and  2014 were estimated using the following weighted-average assumptions:

Performance Restricted Stock Units

We  grant performance restricted stock  units to officers  and certain  employees. The performance
stock unit agreements provide for the  award of performance stock units with each unit representing the
right to receive one share of our common stock to be issued after the  applicable  award  vesting period.
The final number of units awarded, if  any,  for these  performance grants will  be  determined as of  the
vesting dates, based upon our total shareholder return over  the performance  period compared to the
Russell 2000 Index and could range from  no units to a maximum of twice the initial  award  units. The
weighted average fair value for these performance units was  determined  using a Monte  Carlo
simulation model incorporating the following weighted average  assumptions:

Total stock-based compensation cost capitalized as part of inventory during fiscal 2016 was
$2.7 million; $2.6 million was amortized into income  during fiscal 2016, which  includes amounts
capitalized in fiscal 2016 and amounts carried over from  fiscal 2015.  Total stock-based compensation
cost capitalized as part of inventory during fiscal  2015 was $2.5 million; $2.5  million was  amortized into
income during fiscal 2015, which includes amounts  capitalized in  fiscal 2015 and amounts carried over
from fiscal 2014. Management has made  an  estimate of expected forfeitures  and is recognizing
compensation costs only for those equity  awards expected  to vest.

At fiscal 2016 year-end, the total compensation cost related  to  unvested stock-based awards

granted to employees under the Company’s stock plans but not yet  recognized  was approximately
$21.2 million, net of estimated forfeitures of $0.8  million.  This cost will be amortized  on a  straight-line

basis over a weighted-average period of  approximately 1.4  years  and will be adjusted for subsequent
changes in estimated forfeitures.

At fiscal 2016 year-end, the total compensation cost related  to  options  to purchase common  shares
under the ESPP but not yet recognized was approximately $0.2 million. This cost will be amortized on
a straight-line basis over a weighted-average period of approximately one month.

The stock option exercise tax benefits reported in the statement of cash flows results  from the

excess tax benefits arising from tax deductions  in excess of  the  stock-based  compensation cost
recognized, determined on a grant-by-grant basis. During  fiscal  2016, 2015  and 2014  we have  not
generated any excess tax benefits as cash flows from  financing activities.

Stock Awards Activity

At fiscal 2016, 2015 and 2014 year-end, we had 33,500, 86,000  and 107,000 shares subject to stock

options outstanding.

The effective tax rate on income before  income  taxes for  fiscal 2016 of 28.8% was lower than the
statutory rate of 35.0%. This was primarily due to differences  related  to  the benefit of income subject
to foreign tax rates that are lower than  U.S. tax rates including the Singapore  tax exemption,  the
benefit of foreign tax credits and the benefit  of federal research and development tax credits  including
renewal of the federal research and development  tax  credits for fiscal  2015. These  amounts  are partially
offset by deemed dividend inclusions  under  the Subpart F  tax rules, stock-based compensation not
deductible for tax purposes and limitations on  the deductibility of compensation under  IRC
Section 162(m).

In October 2016, Coherent Singapore received an  amended Pioneer Status  tax exemption  from the

Singapore authorities effective from fiscal 2012  through fiscal 2021. The tax  holiday continues  to  be
conditional upon our meeting certain revenue,  business spending and employment thresholds.  The
impact of this tax exemption decreased Singapore income taxes  by approximately $0.7  million in fiscal
2016. There are no tax benefits for fiscal 2015 and fiscal 2014  due to the utilization of net  operating
loss.

In determining our fiscal 2016 and 2015 tax provisions under ASC  Subtopic 740, we calculated the
deferred tax assets and liabilities for  each separate  tax  entity. We  then  considered a  number of  factors
including the positive and negative evidence regarding  the realization of our deferred tax  assets to
determine whether a valuation allowance should be recognized with respect to our deferred  tax assets.
We  determined that a valuation allowance was appropriate  for  a  portion of the  deferred tax assets  of
our  California and certain state research and  development tax  credits, foreign  tax attributes  and foreign
net operating losses at fiscal 2016 and  2015 year-ends.

During  fiscal 2016, we increased our valuation allowance on deferred  tax  assets by $2.1  million to

$17.6 million, primarily due to the increase in California and  certain state research and  development
tax credits which are not expected to  be  recognized. The  Company had U.S. federal deferred tax assets
related to research and development credits,  foreign tax credits and other tax attributes that can be
used to offset federal taxable income in  future periods.  These  credit carryforwards will expire if they
are not used within certain time periods.  As of October  1, 2016, management determined  that  there is
sufficient positive evidence to conclude that  it is  more likely than not sufficient taxable income will
exist in the future allowing us to recognize  these deferred tax  assets. It is possible that some or all
these attributes could ultimately expire  unused. If facts  and  circumstances change in  the future,
management may determine at that time  a  valuation  allowance is necessary. A valuation  allowance
would materially increase our tax expense in the period applied and would  adversely affect  our results
of operations and  statement of financial condition.  Changes in the Company’s  underlying  facts or

We  have various tax attribute carryforwards which include the following:

(cid:127) Foreign gross net operating loss carryforwards are  $13.7 million, of which  $12.8 million have no
expiration date and of which $0.9 million are scheduled  to  expire beginning in  fiscal  year  2030.
A valuation allowance totaling $5.0 million has  been provided  against the foreign gross  net
operating loss carryforwards in certain jurisdictions since the recovery  of the carryforwards  are
uncertain. California gross net operating loss  carryforwards are $12.4  million and are scheduled
to expire in fiscal year 2032. The tax benefit relating to approximately $7.3  million of  the state
gross  net operating loss carryforwards  will  be  credited to additional  paid-in-capital when
recognized.

(cid:127) Federal gross capital loss carryforwards of $0.8  million are scheduled to expire  in fiscal year

2020. State gross capital loss carryforwards of  $1.3 million are scheduled  to  expire in  fiscal  year
2020. No valuation allowance is recorded against the federal gross capital loss  and the  state
gross  capital loss carryforwards since we anticipate that it is  more likely  than not we will  be  able
to utilize the capital loss in the future.

(cid:127) Federal R&D credit carryforwards  of $29.1 million are  scheduled to expire  in fiscal years 2024

to 2036. The tax benefit relating to approximately $0.9 million of  the  federal tax credit
carryforwards will be credited to additional paid-in-capital when recognized. California  R&D
credit carryforwards of $24.6 million have no  expiration date. The tax benefit relating to
approximately $0.5 million of the state tax credit carryforwards will be credited to additional
paid-in-capital when recognized. A valuation allowance totaling $16.0  million, before federal
benefit, has been recorded against California R&D  credit carryforwards  since  the recovery of the
carryforwards are uncertain. Other states  R&D credit carryforwards of $1.8  million are
scheduled to expire in fiscal years 2017  to  2030. A valuation allowance totaling $0.7 million,
before federal benefit, has been recorded against  certain state  R&D  credit carryforwards since
the recovery of the carryforwards is uncertain.

(cid:127) Federal foreign tax credit carryforwards of $14.0 million are scheduled  to  expire in  fiscal  years
2018 to 2023. The tax benefit relating  to  approximately $13.0  million  of the federal foreign tax
credit carryforwards will be credited  to  additional paid-in-capital when  recognized.

We  are subject to taxation and file income tax returns in the U.S. federal  jurisdiction  and in many

state and foreign jurisdictions. For U.S. federal income tax purposes, all  years  prior to fiscal 2011 are
closed. The Company agreed to extend the statutes of limitations for its fiscal  2011 and  2012

U.S. federal tax returns to June 17, 2017 due to an ongoing Advanced Pricing  Agreement (‘‘APA’’)
between the U.S. and Korea. In March  2016, the Internal Revenue  Service (IRS) issued an audit notice
and Information Documentation Requests (IDRs) for fiscal 2013.  The  audit is currently in progress and
the statute of limitation was extended to December  31, 2017. In our major foreign jurisdictions and our
major state jurisdictions, the years prior to fiscal 2011  and 2012, respectively, are  closed  to  examination.
Earlier years in our various jurisdictions  may remain open  for adjustment  to  the extent that we  have
tax attribute carryforwards from those years.

In December 2011 and January 2012, three of our  German subsidiaries  received  notices  of  tax
audits for the fiscal years 2006 through  2010. The audits were completed in  the third quarter of fiscal
2016. As a result of the settlement, our  gross  uncertain  tax  positions decreased by approximately
$4.9 million. The net provision impact  of  the  adjustments  was immaterial to the  consolidated  statement
of operations.

In July 2015 and March 2016, Coherent Kaiserslautern GmbH (formerly Lumera Laser GmbH)

received tax audit notices for the fiscal  years  2010 to 2014. The audit began in August 2015. We
acquired the shares of Lumera Laser  GmbH  in December  2012 and,  pursuant to the terms  of the
acquisition agreement, we should not have  responsibility for any assessments related  to  the
pre-acquisition period. In June, 2016, Coherent Holding GmbH and Coherent  Deutschland  GmbH
each  received a tax audit notice for the fiscal years 2011 to  2014. The audit  began  in the fourth quarter
of fiscal 2016. Coherent GmbH, Coherent  LaserSystems GmbH &  Co. KG and Coherent
Germany GmbH received audit notices  for the period that they were in existence during the fiscal years
2011 through 2014 and the audit work is  scheduled to commence in  January 2017.

We  regularly engage in discussions and negotiations with  tax authorities  regarding tax matters  in

various jurisdictions and management  believes that it has adequately  provided reserves for any
adjustments that may result from tax  examinations.

As of October 1, 2016, the total amount of gross unrecognized tax benefits including  gross interest

and penalties was $20.6 million, of which  $15.6 million, if recognized, would affect  our effective  tax
rate. Our total gross unrecognized tax  benefit  was  classified  as a  long-term taxes payable in the
consolidated balance sheets after reduction  by  certain deferred tax assets.  We include interest and
penalties related to unrecognized tax  benefits within  the provision  for income taxes. As of  October 1,
2016, the total amount of gross interest and penalties accrued was $0.2 million  and it is  classified as
long-term taxes payable in the consolidated  balance  sheets. As of  October 3, 2015, we had accrued
$1.8 million for the gross interest and  penalties and it is classified as  long-term taxes  payable in  the
consolidated balance sheets.

Management believes that it has adequately provided for any adjustments that may result  from tax

examinations. We regularly engage in discussions and negotiations with tax  authorities  regarding tax
matters in various jurisdictions. It is reasonably  possible that  certain  federal, foreign  and state tax
matters may be concluded in the next  12 months.

15. SEGMENT AND GEOGRAPHIC INFORMATION

At October 1, 2016, we were organized into  two  reportable operating segments:  Specialty Lasers
and Systems (‘‘SLS’’) and Commercial Lasers and Components (‘‘CLC’’). This segmentation  reflects the
go-to-market strategies for various products and markets.  While  both segments work to deliver
cost-effective solutions, SLS develops and  manufactures configurable, advanced-performance products
largely serving the microelectronics, scientific research and government programs and OEM
components and instrumentation markets.  The size  and complexity of many of our SLS products
require service to be performed at the customer  site by  factory-trained field service engineers. CLC
focuses on higher volume products that  are  offered  in set configurations.  The product  architectures are
designed for easy exchange at the point of use such  that  product service  and repairs are based  upon
advanced replacement and depot (i.e., factory)  repair. CLC’s  primary  markets  include materials
processing, OEM components and instrumentation and microelectronics.

We  have identified SLS and CLC as  operating segments for which  discrete financial information  is

available. Both units have dedicated  engineering, manufacturing, product  business management and
product  line management functions. A  small portion  of our outside revenue is  attributable to projects
and recently developed products for which  a segment has  not  yet been determined. The associated
direct and indirect costs are presented in the  category  of  Corporate  and other,  along with  other
corporate costs as described below.

Our Chief Executive Officer has been  identified as the  chief  operating decision maker (CODM) as

he assesses the performance of the segments and decides  how to allocate resources  to  the segments.

15. SEGMENT AND GEOGRAPHIC INFORMATION (Continued)

Income from operations is the measure of  profit and loss that our  CODM uses  to  assess performance
and make decisions. As assets are not  a measure used to assess the performance  of  the company by the
CODM, asset information is not tracked  or compiled by segment and is  not  available to be reported  in
our  disclosures. Income from operations  represents the net  sales  less the  cost of sales and direct
operating expenses incurred within the operating segments  as well as  allocated  expenses such as shared
sales and manufacturing costs. We do  not  allocate  to  our  operating segments certain  operating expenses
which  we manage separately at the corporate level. These  unallocated costs  include stock-based
compensation and corporate functions (certain research and development, management, finance, legal
and human resources) and are included  in the results  below  under Corporate and other in the
reconciliation of operating results. Management does not consider unallocated Corporate and other
costs in its measurement of segment  performance.

Acquisition of Rofin

On November 7, 2016, we completed  our  previously announced  acquisition of Rofin pursuant  to

the Merger Agreement dated March 16, 2016. Rofin is one of the  world’s leading developers and
manufacturers of high-performance industrial laser sources and laser-based solutions and components.
As a condition of the acquisition, we are required to divest ourselves of Rofin’s  low power CO2  laser

business based in Hull, United Kingdom, and will report this business separately as  a discontinued
operation until it is divested. The acquisition was an all-cash transaction  at a price of $32.50 per share
of Rofin common stock. The aggregate  consideration  paid  by  us to the former  Rofin stockholders was
approximately $904.5 million, excluding related transaction fees and  expenses.  We  also paid
$15.3 million due to the cancellation of options held by employees of Rofin. We funded the  payment of
the aggregate consideration with a combination  of  our  available cash  on hand and  the proceeds  from
the Euro Term Loan described below.  We are in the process of evaluating the business combination
accounting considerations, including the consideration  transferred and the  initial purchase price
allocation.

Execution of the Credit Agreement

On November 7, 2016, we entered into the  Credit  Agreement by and among us, Coherent

Holding GmbH, as borrower (the ‘‘Borrower’’), and certain  of  our direct  and indirect subsidiaries from
time to time party thereto, as guarantors, the lenders  from time to time party thereto, Barclays
Bank PLC, as administrative agent and L/C Issuer, Bank  of  America, N.A.,  as L/C  Issuer,  and The
Bank of Tokyo-Mitsubishi UFJ, Ltd., as L/C  Issuer. The Credit Agreement provided  for a  670.0 million
Euro  senior secured term loan facility and a $100.0 million senior secured  revolving credit facility with
a $30.0 million letter of credit sublimit  and a  $10.0 million swing line sublimit. We may  increase the
aggregate revolving commitments or  borrow incremental term  loans  in an  aggregate principal amount
of up to $150.0 million, subject to certain  conditions, including obtaining additional commitments from
the lenders then party to the Credit  Agreement  or new lenders. On  November 7, 2016, we borrowed
the full 670.0 million Euros under the Euro Term  Loan and its proceeds  were used  to  finance the
acquisition of Rofin and pay related  fees  and expenses. Also, on November 7,  2016, we  used
10.0 million Euro of the capacity under  the  Revolving Credit Facility for the issuance of a letter of
credit. We expect to use future loans  under the Revolving Credit Facility, if any,  for general corporate
purposes. The Credit Agreement replaces our existing  $50.0 million Credit Agreement with Union
Bank of California.

The terms of the Credit Agreement require Borrower  to  prepay  the  term loans  in certain
circumstances, including from excess  cash  flow  beyond  a threshold amount,  from the receipt of
proceeds from certain dispositions or  from the incurrence of certain indebtedness, and from
extraordinary receipts resulting in net  cash proceeds in excess of $10  million  in any fiscal year.
Borrower has the right to prepay loans  under the Credit Agreement  in whole  or in part at  any time
without premium or penalty. Revolving  loans may be borrowed, repaid and reborrowed until  the fifth
anniversary of the Closing Date, at which  time all outstanding revolving loans must be repaid. The
Euro  Term Loan matures on the seventh  anniversary of  the Closing Date, at which  time all outstanding
principal and accrued and unpaid interest on the Euro Term Loan must be repaid.

Loans under the Credit Agreement bear interest,  at the  Borrower’s  option,  at a rate equal to
either (i) the London interbank offered rate (the ‘‘Eurocurrency  Rate’’)  or (ii) a base rate (the  ‘‘Base
Rate’’) equal to the highest of (x) the  federal funds rate, plus 0.50%, (y) the prime  rate then  in effect
and (z) the Eurocurrency Rate for loans  denominated in  U.S.  dollars  applicable  to  a one-month
interest period, plus 1.0%, in each case, plus an  applicable margin. The applicable margin for term
loans borrowed as Eurocurrency Rate loans, is 3.50% initially,  and  following the  first  anniversary  of  the
Closing Date ranges from 3.00% to 3.50%  depending  on the consolidated total gross leverage  ratio at
the time of determination. For term  loans borrowed as Base  Rate Loans, the applicable margin initially

is 2.50%, and following the first anniversary of the Closing Date ranges from 2.00% to 2.50%
depending upon the consolidated total  gross leverage ratio  at the  time of determination. The applicable
margin for revolving loans borrowed as  Eurocurrency Rate Loans, ranges from 3.75% to 4.25%, and
for revolving loans borrowed as Base  Rate  Loans, ranges from  2.75%  to 3.25%, in  each case, based  on
the consolidated total gross leverage  ratio at the time of determination. Interest on Base  Rate Loans is
payable quarterly in arrears. Interest  on  Eurocurrency Rate Loans is  payable at the end of  the
applicable interest period. Interest periods for Eurocurrency Rate loans may be, at the Borrower’s
option, one, two, three or six months.

The Credit Agreement requires the Borrower to make scheduled quarterly  payments on the Euro

Term Loan of 0.25% of the original principal amount of the Euro Term  Loan, with  any remaining
principal payable at maturity. A commitment fee accrues on any unused portion  of the revolving  loan
commitments under the Credit Agreement  at a  rate  of  0.375% or  0.5%  depending  on the consolidated
total gross leverage ratio at any time of determination. The Borrower is also obligated to pay other
customary fees for a credit facility of  this size  and  type.

On the Closing Date, we and certain  of  our  direct and indirect subsidiaries, as guarantors,

provided an unconditional guaranty of  all obligations of the  Borrower  and  the other loan parties  arising
under the Credit Agreement, the other  loan documents and under swap contracts and treasury
management agreements with the lenders or their affiliates (with  certain limited exceptions).  The
Borrower and the guarantors have also  granted security interests in  substantially  all  their  assets to
secure such obligations.

The Credit Agreement contains customary affirmative covenants, including covenants regarding the

payment of taxes and other obligations,  maintenance  of  insurance, reporting requirements  and
compliance with applicable laws and regulations, and  negative covenants,  including covenants  limiting
the ability of us and our subsidiaries to, among other things, incur debt, grant liens, make investments,
make certain restricted payments, transact with  affiliates,  and sell assets.  The  Credit  Agreement also
requires us and our subsidiaries to maintain a senior secured  net leverage  ratio as  of  the last  day of
each  fiscal quarter of less of than or equal  to  3.50 to 1.00. The  Credit Agreement contains customary
events of default that include, among other things, payment defaults,  cross defaults with  certain other
indebtedness, violation of covenants, inaccuracy  of  representations and  warranties  in any  material
respect, change in  control of us and the  Borrower, judgment defaults, and  bankruptcy  and insolvency
events. If an event of default exists, the lenders may  require  the immediate payment of all Obligations,
as defined in the Credit Agreement, and  may exercise certain other rights and remedies provided for
under the Credit Agreement, the other  loan documents and applicable law. The acceleration of such
obligations is automatic upon the occurrence of a bankruptcy  and  insolvency event of default.

Segment Restatement

As a result of the acquisition of Rofin,  and  subsequent  to  fiscal  2016 year-end, we  announced that

in the first quarter of fiscal 2017 we will reorganize our existing two segments into two new reporting
segments for the combined company,  OEM Laser Systems and  Industrial Lasers and Systems.
Accordingly, our segment information will  be restated retroactively in  the first quarter of fiscal 2017.
