PROXY STATEMENT 

INFORMATION CONCERNING SOLICITATION AND VOTING 

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”) to be held at 9:00 a.m., local time, on March 31, 2011 at the Garden Court Hotel, 
520 Cowper Street, Palo Alto, California 94301, 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 February 25, 2011 to all stockholders entitled to vote at the Annual Meeting. 

Record Date and Share Ownership 

Stockholders of record at the close of business on February 16, 2011 (the “Record Date”) are entitled to notice of and to vote 

at the meeting and at any adjournment(s) thereof.  On the Record Date, 25,428,104 shares of our common stock, $0.01 par value, 
were issued and outstanding. 

Revocability of Proxies 

Any proxy given pursuant to this solicitation may be revoked by the person giving it at any time before its use (i) by 

delivering to us at our principal offices (Attention: Bret M. DiMarco, Corporate Secretary) a written notice of revocation or a duly 
executed proxy bearing a later date, (ii) in the case of a stockholder who has voted by telephone or through the Internet, by making a 
timely and valid telephone or Internet vote, as the case may be, or (iii) by attending the meeting and voting in person.  Please note, 
however, that if your shares are held of record by a broker, bank or other nominee and you wish to vote at the meeting, you must 
obtain a proxy issued in your name from that record holder, and you will need to provide a copy of such proxy at the meeting. 

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 other 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 representative of a stockholder 
of record as of the Record Date for a stockholder of record that is not a natural person.  For directions to attend the Annual Meeting, 
please contact Investor Relations by telephone at (408) 764-4110. 

Voting and Costs of Solicitation 

On all matters, other than the election of directors, each share has one vote.  See “Election of Directors—Vote Required” for 

a description of your cumulative voting rights with respect to the election of directors. 

If you are a stockholder of record as of the Record Date, you may vote in person at the Annual Meeting, vote by proxy using 

the enclosed proxy card, vote by proxy over the telephone or vote by proxy via the Internet.  Whether or not you plan to attend the 
Annual Meeting, we urge you to vote by proxy to ensure your vote is counted.  As stated above, you may still attend the Annual 
Meeting and vote in person if you have already voted by proxy. 

•               To vote in person:  Come to the Annual Meeting and we will give you a ballot at the time of voting.  If you have 

previously turned in a proxy card, please notify us at the Annual Meeting that you intend to cancel the proxy and vote by 
ballot.

•               To vote using the proxy card:  Simply complete, sign and date the enclosed proxy card and return it promptly in the 

envelope provided.  If you return your signed proxy card to us before the Annual Meeting, the designated proxies will 
vote your shares as you direct. 

•               To vote over 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.  Your vote must be 
received by 11:59 P.M. Eastern Time on March 30, 2011 to be counted. 

•               To vote on 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.  Your vote must be received by 11:59 P.M. Eastern Time on March 30, 
2011 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 six nominees for director and for all other proposals other than Proposal Five, which will be voted as “abstain”. 

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 or 
facsimile. 

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 (with respect to proposals other than the election of directors) 
“Against” votes, abstentions and broker non-votes.  A “broker non-vote” occurs when a nominee holding shares for a beneficial owner 
does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that proposal and 
has not received instructions with respect to that proposal from the beneficial owner.  Abstentions will be counted towards the vote 
total for each proposal, and will have the same effect as “Against” votes.  Because directors are elected by a plurality vote, abstentions 
in the election of directors have no impact once a quorum exists.  Abstentions and broker non-votes represented by submitted proxies 
will not be taken into account in determining the outcome of the election of directors.  Abstentions and broker non-votes represented 
by submitted proxies will not be taken into account in determining the outcome of Proposals Two through Five. 

If you hold shares in your name, and you sign and return a proxy card without giving specific voting instructions, your shares 

will be voted as recommended by our Board on all matters and as the proxy holders may determine in their discretion with respect to 
any other matters that properly come before the meeting. 

Deadline for Receipt of Stockholder Proposals 

Proposals of stockholders that are intended to be presented by such stockholders at the annual meeting of stockholders for the 
2011 fiscal year must be received by us no later than the close of business on the 45th day, nor earlier than the close of business on the 
75th day, prior to the one year anniversary of the date these proxy materials were first mailed by us unless the annual meeting of 
stockholders is held prior to March 1, 2012 or after May 30, 2012, in which case, the proposal must be received by us not earlier than 
the 120th day prior to the annual meeting and not later than the later of the 90th day prior to the annual meeting and the tenth day 
following public announcement of the date the annual meeting will be held and must otherwise be in compliance with applicable laws 
and regulations in order to be considered for inclusion in the proxy statement and form of proxy relating to that meeting.  Under the 
federal securities laws, for such a matter to be included in the proxy materials for annual meeting of stockholders for the 2011 fiscal 
year, timely notice must be delivered to us at our principal executive offices to the attention of Bret M. DiMarco, our Corporate 
Secretary, not less than 120 days before the date of our proxy statement released to stockholders in connection with the previous 
year’s annual meeting, which will be October 28, 2011.  Stockholder proposals must otherwise comply with the requirements of 
Rule 14a-8 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).  If a stockholder who has notified us of his or 
her intention to present a proposal at an annual meeting does not appear to present his or her proposal at such meeting, we need not 
present the proposal for vote at such meeting. 

2 
 
  
  
  
   
  
  
  
  
  
  
  
However, if a stockholder wishes only to recommend a candidate for consideration by the Governance and Nominating 

Committee as a potential nominee for the Company’s Board, see the procedures discussed in “Proposal One — Election of Directors 
— Board Meetings and Committees — Process for Recommending Candidates for Election to the Board of Directors.” 

The attached proxy card grants to the proxyholders discretionary authority to vote on any matter raised at the Annual 

Meeting. 

Delivery of Voting Materials to Stockholders Sharing an Address 

To reduce the expense of delivering duplicate voting materials to our stockholders who may hold shares of Coherent common 

stock in more than one stock account, we are delivering only one set of the proxy solicitation materials to certain stockholders who 
share an address, unless otherwise requested.  A separate proxy card is included in the voting materials for each of these stockholders.  
We will promptly deliver, upon written or oral request, a separate copy of the annual report or this proxy statement to a stockholder at 
a shared address to which a single copy of the documents was delivered.  To obtain an additional copy, you may write us at 5100 
Patrick Henry Drive, Santa Clara, California 95054, Attn: Investor Relations, or contact us by telephone at (408) 764-4000 and request 
to be connected to our Investor Relations department.  Similarly, if you share an address with another stockholder and have received 
multiple copies of our proxy materials, you may contact us at the address or telephone number specified above to request that only a 
single copy of these materials be delivered to your address in the future.  Stockholders sharing a single address may revoke their 
consent to receive a single copy of our proxy materials in the future at any time by contacting our distribution agent, Broadridge, 
either by calling toll-free at 1-800-542-1061, or by writing to Broadridge, Householding Department, 51 Mercedes Way, Edgewood, 
NY 11717.  Broadridge will remove such stockholder from the Householding program within 30 days of receipt of such written 
notice, after which each such stockholder will receive an individual copy of our proxy materials. 

Further Information 

We will provide without charge to each stockholder solicited by these proxy solicitation materials a copy of 

Coherent’s annual report on Form 10-K for the fiscal year ended October 2, 2010 without exhibits and any amendments 
thereto on Form 10-K/A upon request of such stockholder made in writing to Coherent, Inc., 5100 Patrick Henry Drive, Santa 
Clara, California 95054, Attn: Investor Relations.  We will also furnish any exhibit to the annual report on Form 10-K if 
specifically requested in writing.  You can also access our Securities and Exchange Commission (“SEC”) filings, including our

(Attention: Bret M. DiMarco, 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, 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 the Company if elected, 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 an annual meeting, 
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 “Information Concerning Solicitation and Voting—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 
recommended by a stockholder, as well as those 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, in 
the Governance and Nominating Committee’s discretion, include a review solely of information provided to the 
Governance and Nominating Committee or may also include discussions with persons familiar with the candidate, an 
interview with the candidate or other actions that the Governance and Nominating Committee deems proper; 

•                  the Governance and Nominating Committee evaluates the performance of the Board as a whole and evaluates the 

performance and 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, judgment, 
independence, age, expertise, diversity of experience, length of service, other commitments and the like.  The 
Governance and Nominating Committee evaluates such factors, among others, and does not assign any particular 
weighting or priority to any of these factors.  The 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 for director candidates, the Governance and Nominating 
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 as may be required by applicable rules, such as financial literacy or 
financial expertise with respect to audit committee members; 

•                  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.

Stockholder Communication with the Board of Directors 

We believe that management speaks for Coherent.  Any stockholder may contact any of our directors by writing to them by 
mail c/o Bret M. DiMarco, Corporate Secretary, at our principal executive offices, the address of which appears on the cover of this 
proxy statement. 

Any stockholder may report to us any complaints regarding accounting, internal accounting controls, or auditing matters.  
Any stockholder who wishes to so contact us should send such complaints to the Audit Committee c/o Bret M. DiMarco, Corporate 
Secretary, at our principal executive offices, the address of which appears on the cover of this proxy statement. 

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

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 memo, which will become part of 
the stockholder communications log that the Corporate Secretary maintains with respect to all stockholder communications.

The amounts shown reflect the grant date fair value of stock options determined pursuant to FASB ASC Topic 718. These 
options vest annually over a three year period. Pursuant to FASB ASC Topic 718, the amounts shown here exclude the effect 
of estimated forfeitures related to service-based vesting conditions. The assumptions used in the valuation of these awards are 
set forth in Note 14, “Employee Stock Option and Benefit Plans” of the Financial Statements in our annual report on 
Form 10-K. 

The directors’ aggregate holdings of RSUs as of the end of fiscal 2010 were as follows (the vesting for which is 100% on 
March 19, 2011 for 2,000 shares (other than for Mr. Krause), 100% on March 11, 2012 for 2,000 shares and 100% on

Our 1998 Directors’ Stock Plan was adopted by the Board on November 24, 1998 and was approved by the stockholders on 

March 17, 1999. The 1998 Directors’ Stock Plan was amended on March 23, 2003, and was further amended on March 30, 2006, 
when the 1998 Directors’ Stock Plan was renamed the 1998 Director Stock Plan (the “1998 Director Plan”). As of September 30, 
2007, 150,000 shares were reserved for issuance thereunder. Under the terms of the 1998 Director Plan, the number of shares reserved 
for issuance thereunder is increased each year by the number of shares necessary to restore the total number of shares reserved to 
150,000 shares.  In the event that the stockholders approve  the adoption of the 2011 Equity Incentive Plan (see Proposal Three), all 
future director grants shall be under such plan and the 1998 Director Plan will terminate other than for outstanding historical grants 
made thereunder. 

9 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The 1998 Director Plan provided for the automatic and non-discretionary grant of a non-statutory stock option to purchase 

24,000 shares of the Company’s common stock to each non-employee director on the date on which such person becomes a director. 
Thereafter, each non-employee director will be automatically granted a non-statutory stock option to purchase 6,000 shares of 
common stock on the date of and immediately following each Annual Meeting of Stockholders at which such non-employee director 
is reelected to serve on the Board, if, on such date, he or she has served on the Board for at least three months. Such plan provides that 
the exercise price must be equal to the fair market value of the common stock on the date of grant of the options. 

Additionally, the 1998 Director Plan provides for the automatic and non-discretionary grant of 2,000 restricted stock units 

(“RSUs”) to each non-employee director on the date on which such person becomes a director. Thereafter, each non-employee 
director will be automatically granted 2,000 RSUs on the date of and immediately following each Annual Meeting of Stockholders at 
which such non-employee director is reelected to serve on the Board, if, on such date, he or she has served on the Board for at least 
three months. The Board of Directors, upon recommendation of its independent compensation consultant, has approved a change 
whereby beginning with our annual meeting on March 31, 2011, non-employee members of our Board of Directors will receive annual 
grants of 3,500 RSUs and no annual stock option grants. 

The 1998 Director Plan provides that with respect to any options held by a director who retires after at least eight years of 
service on the Board, such director will fully vest in and have the right to exercise his or her option as to both vested and unvested 
shares as of such date. The option will remain exercisable for the lesser of (i) two (2) years following the date of such director’s 
retirement or (ii) the expiration of the option’s original term. 

As of October 2, 2010, 344,000 shares have been issued upon the exercise of options and the vesting of restricted stock units 

under the 1998 Director Plan. There were no options exercised by non-employee directors during fiscal 2010. 

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 six (6) 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, the six (6) nominees receiving the highest number of votes will be elected to the Board.  See 

“Information Concerning Solicitation and Voting—Quorum; Abstentions; Broker Non-Votes.” 

THE BOARD RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THE SIX NOMINEES PRESENTED HEREIN.

PROPOSAL TWO 
 RATIFICATION OF APPOINTMENT OF 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 October 1, 2011, 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 2, 2010, 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. 

Principal Accounting Fees and Services 

The following table sets forth fees for services provided by Deloitte & Touche LLP, the member firms of Deloitte Touche 

Tohmatsu, and their respective affiliates (collectively, “Deloitte”) during fiscal years 2010 and 2009:

Represents fees for professional services provided in connection with the integrated audit of our annual financial statements 
and internal control over financial reporting and review of our quarterly financial statements, advice on accounting matters 
that arose during the audit and audit services provided in connection with other statutory or regulatory filings. 

Represents the annual subscription for access to the Deloitte Accounting Research Tool, which is a searchable on-line 
accounting database ($2,000) in both fiscal years, and due diligence associated with our acquisition activities in fiscal 2009. 

Pre-Approval of Audit and Non-Audit Services 

The Audit Committee has determined that the provision of non-audit services by Deloitte is compatible with maintaining 

Deloitte’s independence. In accordance with its charter, the Audit Committee approves in advance all audit and non-audit services to 
be provided by Deloitte. In other cases, the Chairman of the Audit Committee has the delegated authority from the Committee to pre-
approve certain additional services, and such pre-approvals are communicated to the full Committee at its next meeting. During fiscal 
year 2010, 100% of the services were pre-approved by the Audit Committee in accordance with this policy. 

Vote Required 

The affirmative vote of a majority of the votes cast will be required to ratify the selection of Deloitte & Touche LLP as our 

independent registered public accounting firm for the fiscal year ending October 1, 2011. 

THE AUDIT COMMITTEE UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THE 
RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS OUR INDEPENDENT REGISTERED 
PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING OCTOBER 1, 2011.

PROPOSAL THREE 
 APPROVAL OF OUR 2011 EQUITY INCENTIVE PLAN 

Our Board of Directors believes that we must offer a competitive equity incentive program if we are to continue to 
successfully attract and retain the best possible candidates for positions of substantial responsibility within Coherent. Our current form 
of company-wide equity plan, the 2001 Stock Plan, was first adopted in 2001. We believe it appropriate to adopt a new form of 
company-wide equity plan consistent with current best compensation practices. Accordingly, the Compensation and H.R. Committee 
of our Board of Directors has adopted our 2011 Equity Incentive Plan (the “Plan”), subject to, and effective as of, approval from our 
stockholders at the annual meeting.  

If stockholders approve the Plan, there will be no further grants of equity-based awards under the 2001 Stock Plan. However, 

the 2001 Stock Plan will continue to govern awards previously granted under it. The maximum aggregate number of shares that may 
be issued under the Plan is 4,500,000 shares plus any forfeited or cancelled shares subject to outstanding awards under the 2001 Stock 
Plan, 1995 Stock Plan and 1998 Director Option Plan that are outstanding up to a maximum of an additional 2,382,000 shares.  The 
aggregate number of outstanding shares of common stock subject to options  under such plans as of January 1, 2011 was 1,389,314, 
with a weighted average exercise price per share of $28.61 and a weighted average remaining contractual term of 4.1 years.  As of 
January 1, 2011, the aggregate number of unvested full-value awards outstanding was 547,098.  As of the record date, no benefits or 
amounts relating to the 4,500,000 new shares have been received by, or allocated to, any individuals, other than as may be issued 
pursuant to the automatic grants to our non-employee directors discussed elsewhere in this proxy statement.  

The Plan is also designed to allow us to deduct in full for federal income tax purposes the compensation recognized by our 

executive officers in connection with certain awards granted under the Plan. Section 162(m) of the Internal Revenue Code of 1986, as 
amended (the “Code”), generally denies a corporate tax deduction for annual compensation exceeding $1 million paid to the chief 
executive officer and other “covered employees” as determined under Section 162(m) of the Code and applicable guidance 
(“Section 162(m)”). However, certain types of compensation, including performance-based compensation, are generally excluded 
from this deductibility limit. To enable compensation in connection with stock options, stock appreciation rights and certain restricted 
stock grants, stock units, performance shares and performance units awarded under the Plan to qualify as “performance-based” within 
the meaning of Section 162(m), the Plan limits the sizes of such awards as further described below. By approving the Plan, our 
stockholders will be approving, among other things, eligibility requirements for participation in the Plan, performance measures upon 
which specific performance goals applicable to certain awards would be based, limits on the numbers of shares or compensation that 
could be made to participants. The Plan is attached as Appendix A to this proxy statement.  

The Plan permits the granting by our Board of Directors or any of its committees (the “administrator”) of:  

• 

Incentive stock options.  Incentive stock options are options that are intended to qualify for U.S. federal income tax 
purposes as an incentive stock option within the meaning of Section 422 of the Code; 

•  Nonstatutory stock options.  Nonstatutory stock options are options that are not intended to qualify for U.S. federal 

income tax purposes as an incentive stock option;   

•  Restricted stock. Awards of restricted stock are rights to acquire or purchase shares of our common stock, which vest in 
accordance with the terms and conditions established by the administrator in its sole discretion. The award agreement 
will generally grant us a right to repurchase or reacquire the unvested shares upon the termination of the participant’s 
service with us for any reason (including death or disability). The administrator will determine the number of shares 
granted pursuant to an award of restricted stock; 

•  Restricted stock units (RSUs).  Awards of RSUs result in a payment to a participant only if the vesting criteria the 

administrator establishes are satisfied. Upon satisfying the applicable vesting criteria, the participant will be entitled to 
the payout specified in the award agreement. The administrator, in its sole discretion, may pay earned RSUs in cash, 
shares, or a combination thereof. On the date set forth in the award agreement, all unearned restricted stock units will be 
forfeited to us. The administrator determines the number of RSUs granted to any participant; 

• 

Stock appreciation rights (SARs).  The administrator will be able to grant SARs, which are the rights to receive the 
appreciation in fair market value of common stock between the exercise date and the date of grant. We can pay the 
appreciation in cash, common stock of equivalent value, or a combination thereof.  SARs will become exercisable at the 
times and on the terms established by the administrator, subject to the terms of the Plan. The administrator, subject to the 
terms of the Plan, will have complete discretion to determine the terms and conditions of SARs granted under the Plan; 

12 
 
 
 
 
 
 
 
 
 
 
 
provided, however, that the exercise price may not be less than 100% of the fair market value of a share on the date of 
grant; 

•  Performance units and performance shares.  The administrator will be able to grant performance units and performance 
shares, which are awards that will result in a payment to a participant only if the performance goals or other vesting 
criteria the administrator may establish are achieved or the awards otherwise vest. The administrator will establish 
performance or other vesting criteria in its sole discretion, which, depending on the extent to which they are met, will 
determine the number and/or the value of performance units and performance shares to be paid out to participants; 

•  Deferred stock units.  Deferred stock units consist of a restricted stock, RSU, performance share or performance unit 

award that the administrator permits to be paid out in installments or on a deferred basis; and 

•  Dividend equivalents.  Dividend equivalents are credits, payable in cash, made at the discretion of the Plan administrator, 
to the account of a participant in an amount equal to the cash dividends paid on one share for each share represented by 
an Award (other than an SAR or option) held by such participant. 

For purposes of determining shares available for future grant under the Plan, any awards covering shares with a per share or 

per unit price lower than 100% of the fair market value of the shares on the date of grant shall be counted as 2.15 shares against the 
Plan reserve.   

In the event of a merger or change in control, each outstanding award will be assumed or an equivalent option or right 

substituted by the successor corporation or a parent or subsidiary of the successor corporation. In the event that the successor 
corporation refuses to assume or substitute for the award, the participant will fully vest in and have the right to exercise all of his or 
her outstanding options or SARs, including shares as to which such awards that would not otherwise be vested or exercisable, all 
restrictions on restricted stock will lapse, all RSUs will fully vest, and, with respect to awards with performance-based vesting, all 
performance goals or other vesting criteria will be deemed achieved at 100% of target levels and all other terms and conditions met 
unless otherwise expressly provided for in the award agreement. In addition, if an award becomes fully vested and exercisable in lieu 
of assumption or substitution in the event of a change of control, the administrator will notify the participant in writing or 
electronically that the award will be fully vested and exercisable for a period of time determined by the administrator in its sole 
discretion, and the award will terminate upon the expiration of such period. 

Our Board of Directors expects that the Plan will be an important factor in attracting, retaining and rewarding the high caliber 

employees essential to our success and in providing incentive to these individuals to promote the success of the company. If 
stockholders do not approve the Plan we would soon be unable to continue making grants under our 2001 Stock Plan. This would 
make it extremely difficult for us to attract and retain talent. If this proposal is approved, we expect to have an adequate number of 
shares to continue making grants consistent with recent practices for the next two to three years.  The number of awards that an 
employee, director or consultant may receive under the Plan is at the discretion of the administrator and therefore cannot be 
determined in advance. The following table sets forth (i) the aggregate number of shares of common stock subject to options granted 
under the 2001 Stock Plan during the fiscal year ended October 2, 2010, (ii) the average per share exercise price of such options, 
(iii) the aggregate number of restricted stock units granted under the 2001 Stock Plan during the fiscal year ended October 2, 2010, 
and (iv) the dollar value of such restricted stock units. There were no shares issued pursuant to awards of restricted stock, SARs, 
performance units or performance shares granted under the 2001 Stock Plan and 1998 Director Plan during the fiscal year ended 
October 2, 2010.

Vote Required 

The affirmative vote of the holders of a majority of the votes cast will be required to approve our 2011 Equity Incentive Plan.

PROPOSAL FOUR 
ADVISORY VOTE ON EXECUTIVE COMPENSATION 

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 
Discussion and Analysis, the Fiscal 2010 Summary Compensation Table and related tables and disclosure.  

Our Board of Directors recognizes the interest our investors have in the compensation of our executives. In recognition of 

that interest and as required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Dodd-Frank Act"), we 
are providing our stockholders with the opportunity to cast a non-binding advisory vote on the compensation of our named executive 
officers, as disclosed pursuant to the compensation disclosure rules of the SEC (also referred to as "say-on-pay").  

As described in our Compensation Discussion and Analysis, we have adopted an executive compensation philosophy 

designed to provide strong 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. The committee 
positions the midpoint of our target compensation ranges near the 50th percentile of our peers, with actual compensation falling above 
or below depending upon the Company’s financial performance.  

Vote Required  

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 significant vote against the named executive officer 
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.  

Recommendation  

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THE 
APPROVAL OF OUR NAMED EXECUTIVE OFFICER COMPENSATION DISCLOSED IN THIS PROXY STATEMENT 

15 
 
         
PROPOSAL FIVE 
ADVISORY VOTE ON THE FREQUENCY OF ADVISORY VOTES ON EXECUTIVE COMPENSATION 

Our Board of Directors proposes that stockholders provide advisory (non-binding) approval of the frequency of advisory 

votes on executive compensation for upcoming annual meetings of stockholders. 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 Five or by checking the box labeled, “abstain”.  

We are required by the Dodd-Frank Act to provide stockholders with a "say-on-pay" vote every one, two or three years, as 

determined by a separate advisory stockholder vote held at least once every six years.  

Vote Required  

The affirmative vote of the holders of a majority of the votes cast is required to approve the frequency of advisory votes taken 

at 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.  

THE BOARD DOES NOT MAKE A RECOMMENDATION ON THE FREQUENCY OF ADVISORY VOTES ON THE 
COMPENSATION OF THE COMPANY'S EXECUTIVE OFFICERS NAMED IN THE PROXY STATEMENT'S 
SUMMARY COMPENSATION TABLE.

Based upon 25,199,816 shares of Coherent common stock outstanding as of December 31, 2010. Beneficial ownership is 
determined in accordance with the rules of the SEC and generally includes voting or investment power with respect to the 
securities. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, 
each share of Coherent common stock subject to options held by that person that are currently exercisable or will be 
exercisable within 60 days of December 31, 2010 and all RSUs that will vest within 60 days of December 31, 2010, are 
deemed outstanding. For Drs. Ambroseo and Sobey, Ms. Simonet, Messrs. Spinelli, and DiMarco, no shares of performance-
based restricted stock units are included. In addition, such shares, are not deemed outstanding for the purpose of computing 
the percentage ownership of any other person.  This table has been updated to reflect Schedule 13Gs filed with the SEC 
subsequent to the filing of our Form 10-K/A and corrects the holdings of certain individuals due to the vesting of equity 
securities.

Section 16(a) Beneficial Ownership Reporting 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 2010, 
our officers, directors and greater than ten percent stockholders complied with all applicable Section 16(a) filing requirements.

Compensation Discussion and Analysis  

Introduction 

This Compensation Discussion and Analysis addresses the fiscal 2010 compensation for the principal executive officer, the 

principal financial officer, and the other three executive officers at our fiscal year-end who were the most highly compensated 
executive officers of Coherent. These executives are our “Named Executive Officers” (“NEO” or “NEOs”) for fiscal 2010: 

• 

John R. Ambroseo, Ph.D., our president and chief executive officer; 

•  Helene Simonet, our executive vice president and chief financial officer; 

19 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•  Mark S. Sobey, Ph.D., our executive vice president and general manager, specialty laser systems; 

•  Bret M. DiMarco, our executive vice president, general counsel and corporate secretary; and 

•  Luis Spinelli, our executive vice president and chief technology officer. 

This Compensation Discussion and Analysis describes the material elements of our executive compensation program during 

fiscal 2010, as well as compensation decisions made by our Compensation & H.R. Committee (the “committee”) during fiscal 2011 
prior to this analysis. It also provides an overview of our executive compensation philosophy, principal compensation policies and 
practices. Finally, it details how the committee arrived at the specific compensation decisions for our NEOs in fiscal 2010 and the key 
factors considered in these determinations. 

Compensation Overview 

Compensation Philosophy.  Our executive compensation programs are designed to provide strong 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. The committee positions the midpoint of our target compensation ranges 
near the 50th percentile of our peers, with actual compensation falling above or below depending upon the Company’s financial 
performance. Our executive compensation program is designed to foster practices that will enable us to attract, retain, and motivate 
our executives to: 

•  Ensure that the executive team has clear goals and accountability with respect to our financial performance; 

• 

• 

Provide market levels of pay for meeting target performance expectations, with above market pay for performance above 
target and below market pay for performance below target; and 

Promote our culture of integrity by properly rewarding appropriate risk taking, while not promoting excessive risk 
taking. 

Elements of Executive Compensation.  During fiscal 2010, the compensation of our NEOs, primarily consisted of base salary, 

an annual cash incentive award opportunity, and long-term equity incentive awards. For fiscal 2010, on average, 73% of our NEO’s 
target compensation was delivered in the form of variable annual cash incentives or long-term equity incentives. 

The average target pay mix for our named executive officers during fiscal 2010 can be illustrated as follows: 

Average NEO Target FY 10 Pay Mix

Long Term Equity 
Incentives 47%

Base Salary 27%

Annual Cash 
Incentive 26%

Note: The annual cash incentive amounts represent target awards based on base salary and target bonuses in effect during 
Fiscal Year 2010. The Long Term Incentives include Stock Options (based on the dollar amount recognized for financial statement 
reporting purposes for fiscal 2010 in accordance with ASC 718) and Restricted Stock Units (using the grant date face value). This 
chart does not include other benefits, such as perquisites. 

Compensation Governance.  “Pay for performance” is at the core of Coherent’s executive compensation approach. This is 
accomplished primarily by having a majority of the NEOs’ potential compensation being “at risk” through a combination of a fiscal 
year variable cash bonus program and performance metrics in equity grants. In addition to this core philosophy the committee 

20 
 
 
 
 
monitors and considers evolving governance approaches and standards in executive compensation. As more fully discussed below, 
recent examples of how this philosophy is applied and changes made pursuant to compensation best practices, include: 

•  The elimination of the chief executive officer’s 280G “tax gross-up” provision in the change of control severance plan in 

fiscal 2011; 

•  The elimination and phasing-out of all perquisites and Company deferred compensation contributions for executive 

officers beginning in calendar 2011; 

• 

In fiscal 2009 the NEOs received less than $5,000 in total bonus pay-out, as neither the committee nor management 
recommended any modifications to the previously established performance metrics; 

•  Despite the Company meeting the adjusted EBITDA percentage performance goals for pay-out under the 

performance-based RSU grants, the Company did not meet the record revenue threshold set by the committee. Therefore, 
no performance- based RSUs vested at the measurement date in the first quarter of fiscal 2011; 

•  Named executive officers did not receive salary increases for fiscal 2009 or 2010; 

•  Maintained the same target bonus percentage for each NEO in both fiscal 2010 and fiscal 2011; 

• 

In fiscal 2009, the Company adopted a claw-back policy for our chief executive officer and chief financial officer in 
certain circumstances; and 

•  Aside from the change of control severance plan, our executive officers do not have employment or severance 

agreements. 

Certain Fiscal 2010 Operating Results.  Coherent had strong operating performance in fiscal 2010 as compared to fiscal 

2009, including net sales growth of 38.8%, or $169 million, with a corresponding net income growth of over $70 million. 
Accordingly, in fiscal 2010, the compensation for our NEOs increased as compared to fiscal 2009, largely due to the significantly 
improved financial results resulting in the maximum payout under the Company’s fiscal 2010 variable cash incentive plan. 

Compensation process 

Role and Authority of Our Compensation and H.R. Committee 

The committee held six (6) meetings in fiscal 2010. Following our annual meeting in April, 2010, the committee consisted of 

Messrs. Vij (Chair), Krause and Tomlinson and Dr. Rogerson. 

The committee oversees our executive compensation philosophy and administers our executive compensation program. In 

particular, the committee reviews the corporate goals and objectives and approves the compensation for our Named Executive 
Officers. The committee has the sole authority delegated to it by the Board to make equity grants to our Named Executive Officers. 

The committee has adopted a charter, a copy of which may be found on our website at “www.coherent.com”—“Company”—

“Corporate Governance.” The committee targets a review of its charter annually. 

The committee may meet with or without management present, at its discretion. At most of its meetings, the committee 

conducts an executive session without management present. 

Role of Management 

The Compensation and H.R. Committee regularly meets with Dr. Ambroseo, our chief executive officer, to obtain 
recommendations with respect to the compensation programs, practices and packages for our Named Executive Officers other than 
Dr. Ambroseo. Additionally, Ms. Simonet, our executive vice president and chief financial officer, and Mr. DiMarco, our executive 
vice president and general counsel are regularly invited to meetings of the committee or otherwise asked to assist the committee. 
Additionally, during fiscal 2010, members of our human resources group regularly attended the committee’s meetings. The assistance 
of these individuals includes providing financial information and analysis for the committee and its compensation consultant, taking 
minutes of the meeting or 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. Named Executive Officers 

21 
 
will attend portions of committee meetings when requested, but leave the meetings when matters potentially affecting them are 
discussed. At the invitation of the committee, outside legal counsel frequently attends committee meetings. The committee makes 
decisions regarding Dr. Ambroseo’s compensation without him present. 

Role of Compensation Consultants 

In fiscal 2010, the Compensation and H.R. Committee engaged Farient Advisors (“Farient”) as its independent compensation 

consultants. Farient was retained to: 

•  Review and analyze our executive compensation program; 

•  Make recommendations for fiscal 2010 compensation; and 

•  Review the Company’s change of control severance plan. 

Additionally in fiscal 2010, the Board of Directors retained a separate independent compensation consultant, 

Compensia, Inc., to review Board-related compensation matters. After reviewing prevailing governance practices and interviewing 
several compensation consultants, during the fourth quarter of fiscal 2010 the committee determined to consolidate all of the 
independent compensation consultant work with Compensia. Farient completed its work for the committee in the fourth quarter of 
fiscal 2010. In fiscal 2011, the committee worked with Compensia. 

The independent compensation consultant serves at the discretion of the committee and is not permitted to do other work for 

the Company unless expressly authorized by the committee. Since their retention, neither Farient nor Compensia has performed any 
work for the Company other than its work with the committee or for the Board. 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 or the Board. 

We also participate in and maintain a subscription to the Radford Global Technology Survey. This survey provides 
benchmark data and compensation practices reports to assist us with regards to employee compensation generally. Such data includes 
executive compensation data which is presented to the committee at its request. 

Pay Positioning Strategy and Benchmarking of Compensation 

We have striven to position the midpoint of our target compensation ranges near the 50th percentile of our peers, resulting in 

targeted total compensation that is competitive within our labor market for performance that meets the objectives established by the 
committee. A Named Executive Officer’s actual salary, cash incentive compensation opportunity and equity compensation may fall 
below or above the target position based on the individual’s experience, seniority, skills, knowledge, performance and contributions. 
These factors are weighed individually by the committee in its judgment, and no one factor neither takes precedence over others nor is 
any formula used in making these decisions. The chief executive officer’s review of the performance of the other Named Executive 
Officers is considered by the committee in making individual pay decisions. With respect to the chief executive officer, the committee 
additionally considered the performance of Coherent as a whole and the views of 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. 

In analyzing our executive compensation program relative to this target market positioning, the committee reviews 

information provided by its independent compensation consultant, which includes an analysis of data from peer companies’ proxy 
filings with respect to similarly situated individuals at the peer companies and from compensation survey sources, including a broad 
cross-section of technology companies of similar size to Coherent from the Radford Global Technology Survey. 

For pay decisions made in fiscal 2010, Farient recommended that the committee approve modifications to the group of peer 

companies for conducting compensation analyses from proxies to better reflect our size, strategy and business. Accordingly, the 
committee removed Axcelis Technologies, Inc. and GSI Group, Inc. and added Finisar Corp., Infinera Corp., Opnext, Inc., Varian 
Semiconductor and Veeco Instruments to the peer group for fiscal 2010. The committee also was mindful and took into consideration 
Institutional Shareholder Services’ practices with regards to its formulation and use of peer groups and the relative size of peers, 
although the peer group selected is not confined to the Global Industrial Classification System (GICS) code for Coherent. For fiscal 
2011, no changes were made to the group of peer companies. The peer group for fiscal 2010 comprised the following companies: 

Altera Corp. 
Cymer Inc. 
FEI Company 
Finisar Corp. 
FLIR Systems, Inc. 

Integrated Device Tech. 
JDS Uniphase 
Linear Technology 
Newport Corporation 
Opnext, Inc. 

PMC-Sierra, Inc.

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

• 

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

•  Revenue level (as a proxy for complexity) (primarily companies with between $300 million and $1.5 billion in 

revenues); 

•  Geographic location (U.S. technology markets); and 

•  Emphasizing companies with a significant R&D component, a focus on manufacturing and seeking a balance between 

semiconductors and other equipment manufacturers. 

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

for comparison purposes. 

Components of Compensation 

The principal components of our executive officer compensation and employment arrangements during fiscal 2010 included: 

•  Base salary; 

•  Variable cash incentive payments; 

•  Equity awards; and 

•  Other benefits. 

These components were selected because the committee believes that a combination of salary, incentive pay and benefits is 

necessary to help us attract and retain the executive talent on which Coherent’s success depends. The variable cash and equity 
components are structured to allow the committee to reward performance throughout the fiscal year and to provide an incentive for 
executives to appropriately balance their focus on short-term and long-term strategic goals. 

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 information provided by its independent compensation 
consultant with respect to similarly situated individuals at the peer companies to assist it in determining the base salary for each 
Named Executive Officer, depending upon the particular executive’s experience and historical performance. 

During the first quarter of fiscal 2010, upon management’s recommendation, the committee determined to maintain the base 

salaries of the NEOs at their fiscal 2009 levels. 

Effective beginning with the second quarter of fiscal 2011, based on data provided by Compensia, the committee increased 
the base salaries of Drs. Ambroseo and Sobey and Mr. Spinelli as a market adjustment to bring them in line with peer data for their 
positions. Additionally, all Named Executive Officers received a one-time salary increase of $35,000 to help offset the phased-out 
elimination of perquisites. These increases brought certain of the Named Executive Officers above the 50th percentile in the short-
term, which the committee determined was consistent with the phased-out elimination of the perquisites coupled with the strong 
financial performance by the Company in fiscal 2010.

Variable Cash Incentive Compensation 

To focus each executive officer on the importance of the financial performance of Coherent, a substantial portion of each 

individual’s potential short-term compensation is in the form of variable incentive pay tied to committee- established goals. In fiscal 
2010, Coherent maintained one incentive cash program under which executive officers were eligible to receive bonuses, the 2010 
Variable Compensation Plan (“2010 VCP”). 

2010 VCP 

The 2010 VCP was designed to promote the growth and profitability of Coherent. It provided incentive compensation 

opportunity in line with targeted market rates to our Named Executive Officers. Under the 2010 VCP, participants were eligible to 
receive bi-annual bonuses (with measurement periods for the first half and the second half of the 2010 fiscal year). In setting the 
performance goals, the Compensation and H.R. 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 2010 VCP goals were tied to the Company achieving varying 
levels of adjusted EBITDA as a percentage of sales (“adjusted EBITDA %”), with a payout modifier tied to the level of the adjusted 
EBITDA % for each measurement period. Adjusted EBITDA was defined as earnings before interest, taxes, depreciation, amortization 
and certain other non-operating income and expense items and other items, such as the fiscal impact of stock option expensing under 
Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC 718, stock option-related litigation 
costs and settlement related thereto, 2010 VCP earned, impairment or restructuring charges, and the impact of significant acquisitions. 

Due to the continuing worldwide economic downturn, the committee provided for a lower adjusted EBITDA % target in the 
first half of the fiscal year, with a payout cap of 100%. In order to incentivize management to drive improvement in adjusted EBITDA 
% over the course of the year, the committee approved a meaningful step up during the second half of the year and an increased 
payout cap of 200%. For the first half of fiscal 2010 no payout under the 2010 VCP would occur until the Company was profitable on 
a pro forma pre-tax basis, with a minimum revenue threshold. For the second half of fiscal 2010, the minimum threshold of 
achievement for any payment to be made required an adjusted EBITDA % greater than 12.5% in the second half of the year, with a 
minimum revenue threshold. Due to the Company’s significantly improved operating performance, the payout cap was reached for 
both periods.

The committee, in consultation with its compensation consultant, chose these operating results so that the executives were 
incentivized to deliver the type of sustainable operations that benefits our stockholders. Given that only a modest payout was earned 
under the 2009 variable compensation plan, the committee believed that the goals were reasonably difficult to achieve in fiscal 2009. 
Accordingly, when setting the performance goals for the 2010 VCP, the committee again established reasonably difficult achievement 
goals. The Company’s financial performance during fiscal 2010 resulted in a number of all-time financial records for Coherent and, 
accordingly, the payout under the 2010 VCP was demonstrably higher than in the prior fiscal year.

percentage of base salary, (ii) the potential award range as a percentage of base salary, and (iii) the actual award earned for the

This reflects the aggregate bonuses earned by the Named Executive Officers for the applicable half of fiscal 2010 under the 
2010 VCP. 

Variable Compensation Plan 2011 Performance Metrics 

In the first quarter of fiscal 2011, the Committee established performance metrics for the 2011 Variable Compensation Plan 

(the “2011 VCP”). These performance metrics are based upon achieving semi-annual (each six month period of the fiscal year) pro 
forma EBITDA dollar targets, subject to achieving certain bi-annual revenue thresholds. For purposes of the 2011 VCP, “pro forma 
EBITDA” is defined as earnings before interest, taxes, depreciation, amortization, equity compensation expenses, major restructuring 
charges, the impact of mergers and acquisitions and certain other non-operating income and expense items. 

The amount each participant may receive can vary between 0% and 300% of the targeted amount. If the Company fails to 

meet at least the minimum goal for adjusted EBITDA dollar achievement and the revenue threshold for a particular semi-annual 
period, the participant would not receive any bonus for that particular period. The adjusted EBITDA dollar and revenue achievement 
are calculated after the conclusion of each applicable semi-annual fiscal period. The Committee determined the target percentage of 
salary in the 2011 VCP for our NEOs, should remain the same as fiscal 2010: John Ambroseo: 100%; Helene Simonet: 70%; Mark 
Sobey: 60%; Bret DiMarco: 50%; and Luis Spinelli: 50%.

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 targeted peer group median, with the potential for increase for 
exceptional Company financial performance, consistent with the reasonable management of the Company’s overall equity 
compensation expense and stockholder dilution. Finally, we believe that long-term equity awards are an essential tool in promoting the 
retention of our executives. Our long-term incentive program includes the grant of stock options, time-based restricted stock/units 
and/or performance-based restricted stock/units. These components provide a reward for past corporate and individual performance 
and as an incentive for future performance. 

When making its compensation decisions, the committee reviews the compensation overview prepared by its independent 
compensation consultant which reflects potential realizable value under current short and long term compensation arrangements for 
each Named Executive Officer. 

Fiscal 2010 Equity Grants 

In fiscal 2010, the committee granted a combination of non-qualified stock options and time-based restricted stock units. To 

ensure that the grants provided retention and both short and long term incentives, the grants vest over three years through one-year 
annual cliff vesting. 

The following table reflects the grants for the Named Executive Officers for the time-based restricted stock units and non-

qualified stock option grants during fiscal 2010 (in shares):

Fiscal 2011 Equity Grants 

For fiscal 2011, the committee determined to base the equity program on a combination of time-based and 

performance-based restricted stock units. In particular, the committee determined to measure achievement for the performance grants 
against the Company’s relative performance of its common stock versus that of the Russell 2000 Index. The committee believes that 
using the Russell 2000 Index (in which the Company is a member) as a representative of total stockholder return directly aligns 
executive compensation with stockholder interest. The committee determined that both the performance-based and time-based 
restricted stock unit grants provide a further retention tool in that the grants vest over three years with one-year annual cliff vesting 
and, for the performance-based grants, a measurement period for each of the next three years. At target achievement, all Named 
Executive Officers (other than the chief executive officer) will receive an equity distribution of 50% time-based and 50% 
performance-based equity award payouts and the chief executive officer will receive greater than half of his total equity award in 
performance-based equity awards. 

26 
 
 
 
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 performance of the Company’s common stock against the Russell 2000 Index 
through the date of the change of control and such performance-based shares would then convert to time-based vesting with a 
maximum of three one-year vesting cliffs from the grant date.

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 employee is granted an option or restricted stock unit upon beginning employment and may be eligible for 
periodic grants thereafter. The size of grants (and eligibility for the same) is influenced by the then-current guidelines for non-
executive officer grants and the individual’s performance or particular requirements at the time of hire. Employees, including the 
Named Executive Officers, are also eligible to participate in our Employee Stock Purchase Plan. Stock options are granted with an 
exercise price equal to the fair market value of the shares of the Company’s common stock on the grant date (or, on the date of grant 
effectiveness of the grant in the case of grants made during closed window periods). The exercise price for our stock options is based 
on the last quoted price per share of the Company’s common stock as reported on the NASDAQ Global Market on the grant date. 

In fiscal 2010, the Compensation and H.R. Committee granted an aggregate of 681,250 shares subject to options and time-

based restricted stock units, representing 2.76% of Coherent’s outstanding common stock as of October 2, 2010 (excluding automatic 
grants to directors under the Director Option Plan). With the assistance of Farient, the committee has reviewed this burn rate relative 
to peer practices and guidance from RiskMetrics and found that the total dilution was consistent with the median of peer practices and 
complied with RiskMetrics guidelines. 

Stock Grant Process 

The committee’s process for granting equity awards is as follows: 

•  The Compensation and H.R. Committee has the authority to make equity grants to both executive officers and other 

service providers; 

•  The Compensation and H.R. Committee will make grants in open trading window periods with grants effective on the 
date of such meeting, or if they meet during a closed window period, the exercise price of the option grant will be the 
trading date effective 45 days thereafter (or the next trading date thereafter if the date falls on a non-trading day); and 

•  The Compensation and H.R. Committee may not grant equity awards by written consent. 

27 
 
 
 
During fiscal 2010 equity grants were only made by the Compensation and H.R. Committee. 

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 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 Named Executive Officers). 

We maintain a Deferred Compensation Plan for executive management personnel 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 Deferred 
Compensation Plan permits participants to 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. 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 investment alternatives be “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. 

For plan year 2010 for contributions which were in excess of the Internal Revenue Code limit to qualified 401(k) plans, the 

Company will make a non-qualified deferred compensation plan contribution on behalf of the Named Executive Officers. The 
calculation for this non-qualified plan contribution is 4% of eligible compensation (as defined under the Company’s 401(k) plan) less 
the 401(k) plan match limit. In fiscal 2010 the Company made a contribution for the 2009 plan year at a 4% contribution rate. The 
Company will make a similar contribution for the 2010 plan year (which shall be contributed during calendar 2011). The Company 
contribution was eliminated for plan year 2011 and beyond. 

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. 

Severance and Change of Control Arrangements 

We have adopted the Change of Control Severance Plan (the “Change of Control Plan”) which provides certain benefits in 

the event of a change in control of Coherent for certain executives, including each of our Named Executive Officers. Benefits are 
provided if there is a tender offer or merger resulting in Coherent being acquired by another entity and within two years thereafter the 
participant’s employment is terminated without cause or is voluntarily terminated following a constructive termination. 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 Change of Control Plan was amended and restated in the first quarter of fiscal 2011. Among the amendments made to the 

plan in fiscal 2011 were: (i) the elimination of the gross-up payment to be made to the chief executive officer for any excise taxes 
resulting from the application of Section 280G of the Internal Revenue Code; and (ii) the addition of a monthly payment of $2,750 for 
participants in lieu of receiving company- subsidized COBRA benefits, life insurance premiums and/or any other welfare benefits 
under the Plan (36 months for the chief executive officer and 24 months for the other Named Executive Officers). The Change of 
Control Plan was amended in fiscal 2010 for Internal Revenue Code Section 409A-related matters and other administrative matters. 

The committee reviews the provisions of the Change of Control Plan at a minimum every two years at or immediately prior 
to the termination of the plan. The committee believes that reviewing the Change of Control Plan every two years allows for the right 
balance in providing certainty for the participants thereof and 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. 

Executive perquisites and Other Personal Benefits 

In the first quarter of fiscal 2011, the committee determined, upon recommendation from management and in consultation 

with Compensia, to eliminate and phase-out executive perquisites effective January 1, 2011. The use of Company-leased automobiles 

28 
 
was phased-out due to the contractual cost of early termination of the leases. The Company leases of automobiles used by executives 
will terminate in April 2012 (Dr. Ambroseo) and October 2011 (Ms. Simonet and Mr. DiMarco). 

During fiscal 2010, the Company provided our executive officers with an automobile benefit and a capped medical 

reimbursement. 

Automobile Benefit.  During fiscal 2010, the Named Executive Officers were eligible to receive either (a) a monthly 

automobile allowance, or (b) a leased vehicle with up to an aggregate purchase price of up to: (i) $95,000 for the chief executive 
officer and (ii) $75,000 for other Named Executive Officers. For those individuals utilizing the automobile allowance alternative, the 
allowance amount was set annually utilizing a prescribed formula, which equaled $1,500 per month in fiscal 2010. The leased 
automobile alternative is administered by a third party financing agency and the Company pays the monthly lease amount. Executive 
officers are either reimbursed for or provided gas, oil, maintenance and insurance for automobiles leased under this program. 
Participants in the automobile program incur annual imputed income on the personal use of any vehicles under the program, including 
fuel and miles, as determined using the Internal Revenue Code rules. 

Medical Reimbursement.  During fiscal 2010, each Named Executive Officer also received up to $5,000 per calendar year of 

reimbursement for uninsured medical expenses with the Company also paying such executive’s taxes on the amount of the benefit. 

The committee determined, with advice from Farient, that the use of a company-leased vehicle or a car allowance and a 

medical reimbursement benefit were reasonable in the context of the overall compensation levels of our Named Executive Officers, 
were consistent with a number of other peer companies, had been historical components of compensation for executive officers at the 
Company and aided in executive retention. 

One-Time Payment for Equity Expiration 

During the period from November 1, 2006 to December 31, 2007, the Company had imposed a company-wide blackout on 

the exercise of stock options because the Company was not current in its periodic reporting obligations due to its ongoing internal 
investigation into its historical stock option granting practices. Certain non-executive officer employees had option grants expire 
during such period pursuant to the terms of grant. Following such expiration, the Company paid such employees an amount to 
compensate them determined by the difference between $34.21 (which was the highest sales price of the Company’s common stock 
during the blackout period) and the exercise price of their expired stock options. In the first quarter of fiscal 2010, the committee 
approved the payment of the following amounts to certain of the Company’s NEOs, which amounts were determined pursuant to the 
same formula described above for non-executive officer employees. Additionally, as a condition to payment each executive officer 
executed a general release with regards to the expired option grants.

Tax and Accounting Considerations 

The Company’s compensation programs are affected by each of the following: 

•  Accounting for Stock-Based Compensation—The Company accounts for stock-based compensation in accordance with 
the requirements of ASC 718. The Company also takes into consideration ASC 718 and other generally accepted 
accounting principles in determining changes to policies and practices for its stock-based compensation programs. 

• 

Section 162(m) of the Internal Revenue Code—This section limits the deductibility of compensation for our chief 
executive officer and our other most highly compensated Named Executive Officers (other than our 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 Equity Incentive Plan are designed so that option grants and certain 
performance-based full value awards thereunder are fully tax-deductible. Cash compensation and time-based full-value 
awards are generally not qualified as “performance-based” compensation under Section 162(m). We may from time to 
time pay compensation to our executive officers that may not be deductible when, for example, we believe 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 such executive officer. 

29 
 
 
• 

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” that does not satisfy the requirements of 
Section 409A. We believe that we have designed and operated any plans to appropriately comply with Section 409A. 

Other Compensation Policies 

To further align our executive compensation program with the interests of our stockholders, at the end of fiscal 2009, the 

special litigation 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 the Company 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 original financial 
document. 

Compensation Committee Interlocks and Insider Participation and Committee Independence 

During fiscal 2010, the Compensation and H.R. Committee of the Board consisted of Messrs. Vij (Chair), Krause and 

Tomlinson and Dr. Rogerson. John Hart, a former member of the Board, was a member of the committee until his retirement in the 
second quarter of fiscal 2010. None of the members of the Compensation and H.R. Committee has been or is an officer or employee of 
Coherent. None of our executive officers serves 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. 

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 Institutional 
Shareholder Services. 

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 the Company’s Annual Report

Reflects the dollar amount of salary earned in fiscal year 2010. Due to the timing of our fiscal year, fiscal year 2009 included 
27 payroll periods compared to 26 payroll periods in fiscal 2010 and 2008. 

Dr. Sobey was promoted to Executive Vice President and General Manager of Specialty Lasers and Systems (SLS) and 
became an executive officer on April 1, 2010. Accordingly, information for 2009 and 2008 for Dr. Sobey has been omitted. 

Amounts shown reflect the grant date fair value of awards granted in accordance with Financial Accounting Standards Board 
(FASB) Accounting Standards Codification (ASC) Topic 718. 

The amounts shown reflect the grant date fair value of stock options determined pursuant to FASB ASC Topic 718. These 
options vest annually over a three year period. Pursuant to FASB ASC Topic 718, the amounts shown here exclude the effect 
of estimated forfeitures related to service-based vesting conditions. The assumptions used in the valuation of these awards are 
set forth in Note 14, “Employee Stock Option and Benefit Plans” of the Financial Statements in our annual report on 
Form 10-K. These amounts do not correspond to the actual value, if any, that may ultimately be recognized by the Named 
Executive Officers. 

Reflects the dollar amounts earned under the Variable Compensation Plan (VCP) during fiscal 2010, fiscal 2009 and fiscal 
2008. 

For Dr. Ambroseo, Mr. Spinelli and Ms. Simonet “All Other Compensation” includes a payment for expired stock option 
grants that we previously disclosed on Form 8-K dated December 9, 2009. As noted in the Form 8-K, during November 1, 
2006 to December 31, 2007, we imposed a company-wide blackout on the exercise of stock options because we were not 
current in our financial reporting obligations due to an internal historical stock option grant practices investigation. The 
Compensation and H.R. Committee approved payments to these individuals, which amounts were determined pursuant to the 
same formula used for non-executive officers. 

For fiscal 2010, includes (a) amounts contributed by us under the Company’s 401(k) plan ($8,902) and deferred 
compensation plan ($10,177), (b) the use of a Company-leased and maintained automobile (“Car Allowance”) ($12,436), 
(c) the payment described in footnote (6) above ($237,000), (d) payment for buy-out of earned vacation ($1,785) and 
(e) amounts reimbursed pursuant to executive medical reimbursement ($5,228). For fiscal year 2009, includes (a) amounts 
contributed by us under the Company’s 401(k) plan ($13,541) and deferred compensation plan ($20,402), (b) debt 
forgiveness which was reflected on Dr. Ambroseo’s W-2 form during the first quarter of fiscal 2009 for his promissory note 
which was fully forgiven prior to the end of fiscal 2009 ($10,000), (c) a Car Allowance ($29,760), and (d) amounts 
reimbursed pursuant to executive medical reimbursement ($10,236). For fiscal year 2008, includes amounts (a) contributed 
by us under the Company’s 401(k) plan ($13,501) and deferred compensation plan ($19,356), (b) payment for buy-out of

($8,539) and (e) amounts reimbursed pursuant to executive medical reimbursement ($5,463).

The exercise prices indicated are the prices originally recorded by the Company at grant and have not been adjusted to reflect 
any new measurement date as a result of the Company’s historical stock option review. 

Market Value is determined by multiplying the number of shares by $40.20, the closing price of the Company’s common 
stock on October 1, 2010, the last trading date of the fiscal year. 

The performance-based restricted stock units vesting determination date was November 14, 2010. The performance based 
restricted stock units were to vest in an amount which is 0-300% of the target, subject to the achievement of certain 
performance metrics. The amount reflected in the table is the maximum amount or 300% of the target, although none of the 
performance-based restricted stock units vested in November, 2010.

Amounts in this column consist of salary and/or bonus earned during fiscal 2010, which is also reported in the Summary 
Compensation Table. 

Amounts reflect Company contribution payments in excess of the Internal Revenue Code Sections 401(a)(17) and 402(g) 
qualified plan limits made to the non-qualified “Deferred Compensation Plan” for plan year 2009 made in fiscal 2010. 
Amounts reported in this column are also reported in the “All Other Compensation” column of the Summary Compensation 
Table. 

The deferred compensation in a participant’s account is fully vested and is credited with positive or negative investment 
results based on the plan investment options selected by the participant. 

Amounts represent account balances and earnings from the Supplementary Retirement Plan (SRP) which was suspended. 
Deferrals (both executive and Company) into this plan have been suspended. The Deferred Compensation Plan is the only 
non-qualified deferred compensation plan currently available for executive officers. 

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 Named Executive Officers pursuant to the terms of our Change of Control 
Severance Plan in effect as of October 1, 2010. The Change of Control Plan was amended and restated in December, 2010 to, among 
other things, eliminate the tax “gross-up” provisions for the chief executive officer. Other than this plan, there are no other 
employment agreements or other contractual obligations triggered upon a change of control. For purposes of this table, it is assumed 
that each Named Executive Officer’s employment terminated at the close of business on October 1, 2010 (the last business day before 
the end of our fiscal year end on October 2, 2010). These payments are conditioned upon the execution of a form release of claims by 
the Named Executive Officer in favor of us. The amounts reported below do not include the nonqualified deferred compensation 
distributions that would be made to the Named Executive Officers 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 

35 
 
 
 
 
 
 
 
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. The Total Benefit per individual in the table below is does not add to the 
total of the individual components due to rounding within each component.

Equity Compensation Acceleration is the in-the-money value of unvested stock options, time-based restricted stock units 
(RSUs) and performance-based restricted stock units, in each case as of October 1, 2010 at the closing stock price on that 
date ($40.20). The value of accelerated stock options are thus calculated by multiplying the number of unvested shares 
subject to acceleration by the difference between the exercise price and the closing stock price on October 1, 2010; the value 
of accelerated restricted stock is calculated by multiplying the number of unvested shares subject to acceleration by the 
closing stock price on October 1, 2010. This assumes immediate release and vesting of the performance-based restricted 
stock units at the maximum, or 300% of target, achievement. As discussed above, none of these performance-based restricted 
stock units vested in November 2010 and the grants were canceled. The amounts reflected for Equity Compensation 
Acceleration do not reflect any applicable taxes, just gross proceeds. Since the table assumes a triggering event on October 1, 
2010, only those stock options and restricted stock/RSU grants outstanding as of that date are included in the table. 

Estimated reimbursement (by way of a tax “gross-up”) for a 20% excise tax that would be due under Section 4999 of the 
Internal Revenue Code of 1986 on a portion of the amounts reported.  This reimbursement provision was eliminated as part 
of the amendment and restatement of the change of control plan in December, 2010. 

Health Insurance is an estimate of the cost of covering the individual and his or her covered dependents for three years, in the 
case of the chief executive officer and for two years for the other Named Executive Officers. 

The change in control plan provides for the payment of specified compensation and benefits upon certain terminations of the 

employment of the participants following a change in control of the Company. The Board has evaluated the economic and social 
impact of an acquisition or other change of control on its key employees. The Board recognizes that the potential of such an 
acquisition or change of control can be a distraction to its key employees and can cause them to consider alternative employment 
opportunities. The Board has determined that it is in the best interests of Coherent and its stockholders to assure that Coherent will 
have the continued dedication and objectivity of its key employees. The Board believes that the change of control plan will enhance 
the ability of our key employees to assist the Board in objectively evaluating potential acquisitions or other changes of control. 

36 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Furthermore, the Board believes a change of control plan aids us in attracting and retaining the highly qualified, high 
performing individuals who are essential to our success. The plan’s assurance of fair treatment will ensure that key employees will be 
able to maintain productivity, objectivity and focus during the period of significant uncertainty that is inherent in an acquisition or 
other change of control. A change in control of Coherent is defined under the change of control plan as an occurrence of a business 
combination, an acquisition by any person directly or indirectly of fifty percent or more of the combined voting power of our common 
stock or a change in the composition of the Board where less than fifty percent are incumbent directors. 

The change of control plan provides that if within 24 months after a change in control the executive’s employment is 

terminated other than by reason of his or her death, disability, retirement or for cause, or the executive officer terminates his or her 
employment for “good reason,” the executive will receive a lump sum severance payment equal to 2.99 (in the case of Dr. Ambroseo) 
or 2.0 (in the case of Ms. Simonet, Dr. Sobey and Messrs. Spinelli and DiMarco) times the executive’s annual base salary and annual 
bonus (assuming achievement of all performance requirements thereof). “Good reason” is defined in each Agreement as any of the 
following that occurs after a change in control of the Company: certain reductions in compensation; certain material changes in 
employee benefits and perquisites; a change in the site of employment; reduction in the executive’s duties and responsibilities; the 
Company’s failure to obtain the written assumption by its successor of the obligations set forth in the Agreement; attempted 
termination of employment on grounds insufficient to constitute a basis of termination for cause under the terms of the change of 
control plan; or the Company’s breach of any of the provisions of the change of control plan. Under the terms of the plan, the 
executives will also have acceleration of all vesting conditions for equity grants and a payment in lieu of health care for the executive 
(and his or her covered family members) will be provided on the same terms for two years and, in the case of Dr. Ambroseo, three 
years.

These weighted average exercise prices do not reflect the shares that will be issued upon the payment of outstanding awards 
of RSUs. 

This number does not include any options which may be assumed by us through mergers or acquisitions, however, we do 
have the authority, if necessary, to reserve additional shares of common stock under these plans to the extent necessary for 
assuming such options. 

This number of shares includes 300,745 shares of common stock reserved for future issuance under the Employee Stock 
Purchase Plan, 132,000 shares reserved for future issuance under the 1998 Director Plan and 2,388,066 shares reserved for 
future issuance under the 2001 Stock Plan. 

The 1998 Director Plan provides for annual increases to the number of shares available for issuance under the 1998 Director 
Plan so that the total number of shares reserved is not less than 150,000 shares.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS 

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.  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 eleven (11) times either in person or by telephone during fiscal 2010.  In the course of these 

meetings, the Audit Committee met with management, the internal auditors and our independent auditors 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 Audit Committee believes that a candid, substantive and focused dialogue with the internal auditors and 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 the auditors themselves prepared and been responsible 
for the financial statements? 

•                  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 2010 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 Statement on 
Auditing Standards No. 61, as amended, (AICPA, Professional Standards, Vol. 1 AU section 380), as adopted by the Public Company 
Accounting Oversight Board in Rule 3200T, and it received the written disclosures and the letter from Deloitte & Touche LLP 
required by the applicable requirements of the Public Company Accounting Oversight Board regarding Deloitte & Touche LLP’s 
communications with Audit Committee concerning independence and has discussed Deloitte & Touche LLP’s independence with 
Deloitte & Touche LLP. 

Management has reviewed the audited financial statements for fiscal 2010 with the Audit Committee, including a discussion 

of the quality and acceptability of the financial reporting, the reasonableness of significant 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 (and the Board 

approved) that the audited financial statements be included in the annual report on Form 10-K for the fiscal year ended October 2, 
2010, for filing with the SEC.

ITEM 1.  BUSINESS 

GENERAL 

Business Overview 

Our fiscal year ends on the Saturday closest to September 30. Fiscal years 2010, 2009 and 2008 ended on October 2, 
October 3, and September 27, respectively, and are referred to in this annual report as fiscal 2010, fiscal 2009 and fiscal 2008 
for convenience. Fiscal year 2009 included 53 weeks; fiscal years 2010 and 2008 included 52 weeks. 

We are one of the world’s leading suppliers of photonics-based solutions in a broad range of commercial and 
scientific research 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: Commercial Lasers and Components (“CLC”) and Specialty Lasers 

and Systems (“SLS”). This segmentation reflects the go-to-market strategies for various products and markets. While both 
segments deliver cost-effective photonics solutions, 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 and original equipment manufacturer (“OEM”) components and instrumentation. SLS develops and 
manufactures configurable, advanced performance products largely serving the microelectronics, OEM components and 
instrumentation and scientific research and government programs 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. 

Effective as of the beginning of the first quarter of fiscal 2009, we moved our diode pumped solid state (“DPSS”) 

Germany and Crystal product families from the CLC segment into the SLS segment. This concentrated all DPSS product 
families in the SLS segment. All reporting has been aligned to reflect the revised reportable operating segments (CLC and 
SLS) and prior periods have been restated. See additional discussion in Note 18 “Segment and Geographic Information” of 
our Notes to Consolidated Financial Statements. 

Income (loss) from operations is the measure of profit and loss that our chief operating decision maker (“CODM”) 
uses to assess performance and make decisions. Income (loss) 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.

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 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., 10−18 seconds). 

4 
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 or solid state crystal. We manufacture all of these types 
of lasers. Lasers can also be classified by their output wavelength: ultraviolet, visible, infrared or wavelength tunable. We 
also 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 broad 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 the laser is the enabling tool that makes the work possible (e.g. the production of sub 50 micron microvias). 

Key laser applications include: micro and nanotechnologies; solar cell production; semiconductor inspection; 

microlithography; measurement, test and repair of electronic circuits; flat panel display manufacturing; medical and bio-
instrumentation; industrial process and quality control; materials processing; 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. The short wavelength of lasers that produce light in the UV spectral region 
makes it possible to manufacture extremely small structures with maximum precision—consistent with the latest state-of-the-
art technology. 

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: 

•  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 expand into new markets, such as laser based processing development tools for solar 
manufacturing and high power materials processing solutions. 

•  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. 

•  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. 

•  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. 

• 

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. 

•  Focus on long-term improvement of adjusted EBITDA, in dollars and as a percentage of net sales—We 
define adjusted EBITDA as earnings before interest, taxes, depreciation, amortization, stock compensation 
expenses and certain other non-operating income and expense items. Key initiatives to reach our goals for 
EBITDA improvements include our program of consolidating manufacturing locations, rationalizing our supply 
chain and selective outsourcing of manufacturing operations. 

5 
APPLICATIONS 

Our products address a broad range of applications that we group into the following markets: Microelectronics, 

Scientific Research and Government Programs, OEM Components and Instrumentation and Materials Processing. 

Microelectronics 

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

phones, tablets, personal computers (“PC’s”) and televisions (“TV’s”) are driving advances in displays, integrated circuits 
and printed circuit boards (“PCB’s”). 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 four major markets in the microelectronics industry: (1) semiconductor front-end, (2) advanced 
packaging and interconnects, (3) flat panel display manufacturing, and (4) solar cell production and other emerging 
processes. 

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, Sapphire, and Excimer lasers are used to detect and characterize defects in semiconductor 
chips. 

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 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 wafers based on low-k 
materials and thinner silicon. Our AVIA and Matrix lasers are providing economic methods of cutting and scribing these 
wafers while delivering higher yields than traditional mechanical methods. Our DIAMOND carbon dioxide (“CO2”) lasers 
are used for singulating packages and printed circuit boards into individual components for final assembly. Our Talisker 
lasers are used in a broad range of applications requiring high precision and low heat damage, such as in thin wafer cutting 
and drilling. 

These same trends are also driving integration and miniaturization, blurring the traditional lines between formerly 
discrete applications such as assembly and PCB fabrication. Lasers are playing several enabling roles in this integration and 
miniaturization. For instance, lasers are now the only economically practical method for drilling microvias in chip assemblies 
and in both rigid and flexible printed circuit boards. These microvias are tiny interconnects that are essential for enabling 
high-density circuitry commonly used in mobile handsets and advanced computing systems. Our AVIA and DIAMOND 
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. 

6 
Other applications have developed as well. For instance, the high density of the latest circuit boards is reaching the 
limits of conventional printing technologies, causing wider adoption of laser direct write methods. Our Paladin laser is used 
for this application. 

Microelectronics—flat panel display manufacturing 

The high-volume consumer market is driving the production of flat panel displays (“FPDs”) in applications such as 

mobile telephones, tablets, laptop computers, television monitors, digital cameras, personal digital assistants (“PDAs”) and 
car navigation systems. There are several types of established and emerging displays based on quite different technologies, 
including plasma (“PDP”), liquid crystal (“LCD”) and organic polymers (“OLED”). Lasers have found applications in each 
of these technologies given that the laser provides higher process speed, better yield, 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, the 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”) 
and sequential lateral solidification, have allowed high-volume production of low-temperature polysilicon (“LTPS”) on 
conventional glass substrates. Our excimer lasers provide an invaluable solution for both ELA and sequential lateral 
solidification because they are the only industrial-grade excimer lasers with the high pulse energy these methods require. The 
current state-of-the-art product for this application is our excimer VYPER laser. 

Our AVIA and DIAMOND lasers are also used in other production processes for FPDs. These processes include 

drilling, cutting, patterning, marking and yield improvement. 

Lasers have also become a valuable tool in high-brightness (HB) LED manufacturing, improving LED performance 
and yield. LED has seen rapid growth in the last year due to wide spread adoption as the light source in all categories of LCD 
displays, from phones all the way to full size TV’s. Our lasers are used in the back-end processing of HB-LEDs. 

Microelectronics—solar cell production 

Numerous areas of microelectronics can be grouped as “emerging technologies.” Some of these are transitioning to 

volume production in the present timeframe while others are more forward-looking. 

Today’s higher energy costs have led to heightened interest in solar panels. The recent growth and interest in solar 

cell technology coupled with the intense focus on improving cell efficiency, is driving the adoption of laser technology in the 
manufacturing of solar cells. Our lasers, such as AVIA, Paladin, Matrix and Talisker, are already being used in the 
production of solar panels for cell isolation and transparent conductive oxide (“TCO”) scribing purposes. 

We have introduced a number of complete solutions for certain processes in the manufacturing of solar cells 

including the Coherent Equinox laser system and the Aethon laser system. These systems are based on Coherent lasers and 
can be used in a production or process development environment. 

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, Legend, Libra, MBD, MBR, Micra, 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. 

Subsequently, 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 as short as few attoseconds (10-18 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. 

7 
OEM Components and Instrumentation 

Instrumentation is one of our more mature commercial applications. Representative applications within this market 
include bio-instrumentation, graphic arts and display, machine vision, and medical OEMs. We also support the laser-based 
instrumentation market with a range of laser-related components, including diode lasers for optical pumping. Some of 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 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. Specifically, our Sapphire, Compass 
and Coherent CUBE 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. Our Compass and Sapphire series of lasers are used in the retinal scanning market 
in diagnostic imaging systems as well as new ground breaking in-vivo imaging applications. In addition, we have a leading 
position in Lasik and photorefractive keratectomy (“PRK”) surgery methods with our ExciStar XS excimer laser platform. 

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. This technology is 
finding traction with both medical OEMs and ophthalmologists. 

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 cladding and hardening of metals, joining materials, and other 
materials processing applications. Other applications include welding of plastics and direct metal welding. In April 2007, we 
acquired Nuvonyx, Inc., a technology leader in high-power laser diode components, arrays, and industrial laser systems for 
materials processing and defense applications. The Nuvonyx products, now integrated within our Semiconductor business, 
provide high power arrays with powers in excess of 50 Kilowatts through its proprietary cooling and stacking technologies. 
Our HighLight product is a direct diode system for metal processing based on the Nuvonyx technology. Complementing our 
progress into higher powered lasers, in fiscal 2009, we introduced the DIAMOND E 1000, the highest power, completely 
sealed CO2 laser for use in materials processing. 

We also participate in the low to medium power area, including such applications as the cutting and joining of 

plastics using both our DIAMOND CO2 lasers and Highlight FAP semiconductor lasers; the cutting, perforating and scoring 
of paper and packaging materials; and various cutting and patterning applications in the textile industry. 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. 

During 2010 we acquired Beam Dynamics, Inc., a manufacturer of flexible laser cutting tools for the materials 

processing market. These tools, when combined with Coherent’s medium to high power CO2 lasers, offer a unique blend of 
performance and precision in a small lightweight tool for cutting of metals and non-metals. Enabled with the DIAMOND 
E1000, the new METABEAM 1000 offers the industry’s most compact 1kW tool, with tools footprints at least 50% smaller 
than competitive designs. Operating costs, due to the sealed nature of the DIAMOND series of CO2 lasers are 75% less than 
similar, but larger tools. 

8 
Laser marking and coding are generally considered part of the precision materials processing applications market for 

which we remain a leading supplier. One such area where applications are growing rapidly is the displacement of ink-jet 
coding due to both aesthetic and environmental pressures. 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. We 
provide lasers for all-important marking applications. Our DIAMOND 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 
product line of reliable, compact and low-cost diode pumped solid state lasers provides an ideal solution for marking of other 
materials in high volume manufacturing. 

FUTURE TRENDS 

Microelectronics 

After several years of process development, lasers are now used in mass production applications because these 

laser-based fabrication and testing methods are faster, deliver superior end products, increase yields, and/or cut production 
costs. We anticipate this trend to continue, driven primarily by the increasing sophistication of consumer electronic goods 
and their convergence via the internet, resulting in increasing demand for better displays, more bandwidth and memory, while 
at the same time consuming less power. Although this market follows the macro-economic trends and carries inherit risks, we 
believe that Coherent is very well positioned to continue to capitalize on the current market trends and that we will see 
continued increased adoption of solid-state, CO2 and excimer lasers, as all these lasers enable performance improvements and 
reduced process costs. In particular, we expect future demands in the flat panel display for excimer laser-based tools, since 
these are the best commercial technology which can be used in the recrystalization of Silicon to enhance display brightness. 

Lasers have emerged as an essential technology in the manufacturing of solar cells. We expect that this trend will 
continue over the next few years as solar cell manufacturing capacity increases. There will be a need for laser sources and 
systems in both process development and production tools as the need for higher solar cell efficiency increases. 

Scientific research and government programs 

The scientific market has benefited from stimulus funding during fiscal 2010, with applications in ultrashort pulses 
and in bio-research being the drivers of this anticipated expansion. We anticipate an increasingly competitive market and a 
flattening of demand; however we expect to retain and improve our market share through new product development and 
maintain our service commitment to this area. 

OEM components and instrumentation 

The instrumentation market is seeing a gradual migration from the use of mature laser technologies, such as 

water-cooled ion gas lasers, to new technologies, primarily based on solid state and semiconductors. Using our unique 
portfolio of solid-state and semiconductor lasers, and our patented OPSL technology, we are able to both assist and stimulate 
this transition as well as to be the technology of choice for developing applications such as security and clinical diagnostics. 
Our OPSL technology resulted in the first truly continuous solid-state UV laser which enables the use of UV in a clinical as 
well as a research environment. Furthermore we anticipate greater future opportunities in bio-instrumentation, including 
DNA sequencing, drug discovery, flow cytometry, and microscopy, based on our product enhancements and evolving market 
developments. Our newer laser technologies are the basis of a number of clinical procedures. In the area of photocoagulation, 
the Genesis OPSL yellow lasers are being used as the wavelength is particularly suitable for the treatment of blood vessels. In 
aesthetic laser surgery, we are an OEM supplier of CO2 lasers to the major manufacturers of aesthetic equipment used in the 
latest procedures for skin enhancement. 

Materials processing 

The market for low to medium power lasers used in industrial materials processing has experienced a nice rebound 

and is expected to continue for the foreseeable future. Key design wins as well as more favorable markets 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. Several factors are enabling us to gain market share in the materials 
processing market. First, we have developed an expanded portfolio of lasers with a broad spectrum of wavelengths, enabling 
optimum marking solutions for virtually every metal and non-metal material type. At the same time, the reliability of these 
products has been achieved at even higher levels, lowering the cost of ownership.

*Coherent sells its laser measurement and control products into a number of these applications. 

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 and crystal 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 (“DPSS”) 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. In fiscal 2008, we 
launched our first product based on fiber laser technology, the Talisker. This is an industrial ultrafast laser system which 
incorporates fiber laser technologies as a key part of the laser design. The Talisker is a new laser platform based on a fiber 
oscillator and crystal amplifier and is illustrative of our strategy of developing and incorporating fiber lasers where they can 
generate unique and cost-effective performance. We expect the Talisker platform will lead to a series of new ultrafast lasers 
for a number of commercial markets including microelectronics and medical. In fiscal 2009, we demonstrated a 1KW fiber 
laser product based on our high power diode laser system, the Highlight 1000F. This prototype demonstrated the platform for 
a scalable, kilowatt class fiber laser based on a bar pumping design. Due to packaging efficiency, diode bars reduce the 
overall cost of a fiber laser. 

Fiber laser technology continues to be an important investment and product development area and we anticipate 

more products that incorporate fiber as the active gain medium. Earlier this year, we acquired the business assets of Stocker-
Yale, Inc. which included a fiber manufacturing facility capable of producing both active and passive fibers. 

Gas lasers (CO2, Excimer, Ion) 

The breadth of our gas laser portfolio is industry leading, encompassing CO2, excimer and ion 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, and materials processing applications. 

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 and graphic 

arts and display markets. In fiscal 2009, our Genesis yellow laser continued to make progress in ophthalmology and we have 
expanded our offerings in the area of entertainment lighting using a variety of products across the visible spectrum. We also 
continued 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 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. 

11 
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, and plastic 
welding. 

Ultrafast (“UF”) Lasers 

Ultrafast lasers are lasers generating light pulses with durations of a few femtoseconds (10-15 seconds) to a few tens 

of picoseconds (10-11 seconds). These types of lasers are primarily used for scientific research and also are finding use in 
sophisticated materials processing applications. Ultrafast lasers are usually pumped by a green DPSS laser. 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 10-500 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 minimal thermal damage. 

SALES AND MARKETING 

We market our products domestically through a direct sales force. Our foreign sales are made principally to 
customers in Europe, Japan and other Asia-Pacific countries. We sell internationally through direct sales personnel located in 
Canada, France, Germany, Italy, Japan, the Netherlands, the People’s Republic of China, South Korea, and the United 
Kingdom, as well as through independent representatives in certain jurisdictions around the world. Foreign sales accounted 
for 67% of our total net sales in fiscal 2010, 66% of our total net sales in fiscal 2009 and 68% of our total net sales in fiscal 
2008. In fiscal 2010, sales to Asian markets grew at a faster rate than sales to other geographic regions. 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. Our products are broadly distributed and no one customer accounted for more than 10% of total net sales 
during fiscal 2010, 2009 or 2008. 

We maintain a customer support and field service staff in major markets within the United States, Europe, Japan, the 

People’s Republic of China, Korea 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 committed to the development of new products, as well as the improvement and refinement of existing 

products, including better cost-of-ownership. 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 2010 were $72.4 million, or 12.0% of net sales compared to $61.4 million, or 14.1% of net sales for 
fiscal 2009 and $74.3 million, or 12.4% of net sales for fiscal 2008. 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 
available from external sources cost-effectively. 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. 

12 
Committed to quality and customer satisfaction, we design and produce many of our own components and sub-

assemblies in order to retain quality control. We have also outsourced certain components, sub-assemblies and finished goods 
where we can maintain our high quality standards while improving our cost structure. We have consolidated and closed 
certain of our manufacturing facilities in order to reduce our footprint, realize synergies, and improve our cost structure and 
operating leverage. In fiscal 2007, we completed the transfer of production of laser power supplies from Auburn, California 
to a global electronics contract manufacturer. During fiscal 2008, we consolidated our Munich DPSS manufacturing into our 
Lübeck, Germany site. The transfer was completed in the fourth quarter of fiscal 2008. In the first quarter of fiscal 2009, we 
announced the consolidation of the remainder of our Munich facility (primarily Excimer laser manufacturing) into our 
Göttingen site. The transfer was completed in the third quarter of fiscal 2009. In fiscal 2009, we outsourced one of our laser 
product lines to a contract manufacturer located in Asia and outsourced our laser optics manufacturing to an optics 
manufacturer located in North America. The supply from these strategic contract manufacturers is covered by long term 
supply agreement contracts. During the second quarter of fiscal 2009, we announced the consolidation of our St. Louis, 
Missouri facility into our Santa Clara, California site. The transfer was completed in the fourth quarter of fiscal 2009. During 
the second quarter of fiscal 2009, we announced our plans to close our Tampere, Finland facility and establish manufacturing 
capabilities at our Sunnyvale, California site. The closing of our Finland facility is expected to be completed during the third 
quarter of fiscal 2011. During the first quarter of fiscal 2010, we announced the acquisition of certain assets of StockerYale 
and our plans to vacate its Montreal facility. We completed the outsourcing and transfer of the Montreal operations during the 
third quarter of fiscal 2010. 

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 and crystals, 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, 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—We 

depend on sole source or limited source suppliers, both internal and external, for some of our key components and materials, 
including exotic materials and crystals, in our products, which make us susceptible to supply shortages or price fluctuations 
that could adversely affect our business” in Item 1A, which is incorporated herein by reference. 

Operations 

Our products are manufactured at our sites in Santa Clara and Sunnyvale, California; Wilsonville, Oregon; East 

Hanover, New Jersey; Bloomfield, Connecticut; Lübeck, Germany; Göttingen, Germany; Glasgow, Scotland; Salem, New 
Hampshire and Tampere, Finland. 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, 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 New Hampshire facility. Our CO2 gas lasers are manufactured in 
Bloomfield, Connecticut. We manufacture a portion of our DPSS lasers used in microelectronics and OEM components and 
instrumentation applications in Lübeck, Germany. Our excimer gas laser products are manufactured in Göttingen, Germany. 
We manufacture the fiber lasers and a portion of our DPSS lasers used in microelectronics and scientific research 
applications in Glasgow, Scotland. Our facilities in Tampere, Finland and Sunnyvale, California grow the aluminum-free 
materials that are incorporated into our semiconductor lasers. Effective the third quarter of fiscal 2011, we expect that the 
entire demand for this material will be grown in our Sunnyvale, California facility. 

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 2, 2010, we held approximately 395 U.S. and foreign patents, which 
expire from 2010 through 2027 (depending on the payment of maintenance fees) and we have approximately 132 additional 
pending patent applications that have been filed. The issued patents cover various products in all of the major markets that we 
serve. 

13 
For a discussion of the importance to our business of, and the risks attendant to intellectual property rights, see “Risk 

Factors—Risks Associated with Our Industry, Our Business and Market Conditions” ‘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. 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 Item 1A, which is incorporated herein by reference. 

COMPETITION 

Competition in the various photonics markets in which we provide products is very intense. We compete against a 
number of companies including CVI Melles Griot, Cymer, Inc., GSI Group, Inc., IPG Photonics Corporation, JDS Uniphase 
Corporation, Newport Corporation, Rofin-Sinar Technologies, 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 2010 year-end, our backlog of orders scheduled for shipment (generally within one year) was 

$262.0 million compared to $164.3 million at fiscal 2009 and $183.5 million at fiscal 2008 year-ends. Orders used to 
compute backlog are generally cancelable without substantial penalties. Historically, the rate of cancellation experienced by 
us has not been significant. 

SEASONALITY 

We have historically experienced decreased bookings and 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 many of our customers due to year-end 
holidays. This historical pattern should not be considered a reliable indicator of the Company’s future net sales or financial 
performance. 

EMPLOYEES 

As of fiscal 2010 year-end, we had 2,006 employees. Approximately 341 of our employees are involved in research 
and development; 1,154 of our employees are involved in operations, manufacturing, service and quality assurance; and 511 
of our employees are involved in sales, marketing, finance, legal 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 April 29, 2010, we acquired Beam Dynamics, Inc. for $5.9 million in cash and $0.3 million in deferred 

compensation related to an employment contract, which will be recognized in expense as earned. Beam Dynamics 
manufactures flexible laser cutting tools for the materials processing market. Beam Dynamics has been included in our 
Commercial Lasers and Components segment. 

On October 13, 2009, we acquired all the assets and certain liabilities of StockerYale, Inc. (“StockerYale”)’s laser 

module product line in Montreal and its specialty fiber product line in Salem, New Hampshire for $15.0 million in cash. 
StockerYale designs, develops and manufactures low power laser modules, light emitting diode (LED) systems and specialty 
optical fiber products. These assets and liabilities have been included in our Commercial Lasers and Components segment. 

We consummated no acquisitions in fiscal 2009 or 2008. 

Please refer to “Note 4. Business Combinations” of Notes to Consolidated Financial Statements under Item 15 of 

this Annual Report on Form 10-K for further discussion of the acquisitions completed during fiscal 2010. 

14 
RESTRUCTURINGS AND CONSOLIDATION 

During the first quarter of fiscal 2010, we acquired the assets and certain liabilities of StockerYale, Inc’s laser 

module product line in Montreal, Canada and began to transition those activities to other Coherent facilities in Salem, 
Massachusetts, Wilsonville, Oregon and Sunnyvale, California. The transfer is scheduled to be completed by the end of 
March 2011. The current year severance related costs are primarily comprised of severance pay, outplacement services, 
medical and other related benefits for employees being terminated due to the transition of activities out of Montreal, Canada, 
and Tampere, Finland. 

During the second quarter of fiscal 2009, we announced our plans to close our facilities in Tampere, Finland and 

St. Louis, Missouri. The closure of our St. Louis, Missouri and Yokohama, Japan sites were completed in the fourth quarter 
of fiscal 2009. The closure of our Finland site was scheduled for completion by the end of fiscal 2010, but we have delayed 
the closure due to a significant increase in demand for products manufactured in Finland. We currently anticipate exiting the 
facility in the third quarter of fiscal 2011. These closure plans have resulted in charges primarily for employee termination 
and other exit related costs associated with a plan approved by management. 

During fiscal 2008, we consolidated our German DPSS manufacturing into our Lübeck, Germany site. The transfer 

was completed in our fourth quarter of fiscal 2008. On October 13, 2008, we announced the consolidation of the remainder of 
our Munich facility into our Göttingen site. The transfer was completed in our third quarter of fiscal 2009. The consolidation 
and transfers have resulted in charges primarily for employee terminations, other exit related costs associated with a plan 
approved by management and a grant repayment liability. 

On April 16, 2008, we announced that we entered into an agreement to sell certain assets of our Auburn Optics 

(“Auburn”) manufacturing operation to Research Electro-Optics, Inc. (“REO”), a privately held optics manufacturing and 
technology company. We also entered into a strategic supply agreement with REO. REO is providing optical manufacturing 
capabilities for us, including fabrication and coating of optical components. The transition of the optics manufacturing assets 
from Auburn to REO was substantially completed in second quarter of fiscal 2009. The transition has resulted in charges 
primarily for employee terminations, supplier qualification, moving costs for related equipment, and other exit related costs 
associated with a plan approved by management. 

GOVERNMENT REGULATION 

Environmental regulation 

Our operations are subject to various federal, state and local environmental protection regulations governing the use, 
storage, handling and disposal of hazardous 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. We believe that compliance with federal, state and local environmental protection 
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. 

We may face potentially increasing complexity in our product designs and procurement operations as we adjust to 

requirements relating to the materials composition of products entering specific markets. Such regulations went into effect in 
the European Union (“EU”) in 2006, and China in 2007. We could face significant 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. In addition, the EU has added the Registration, Evaluation and Authorization of Chemicals 
Regulation, otherwise known as the REACH Regulation, which further regulates substances and products imported, 
manufactured or sold within the EU. Similar laws are now pending in various jurisdictions around the world, including the 
United States. 

We further discuss the impact of environmental regulation under “Risk Factors—Compliance or the failure to 

comply with current and future environmental regulations could cause us significant expense.” 

15 
SEGMENT INFORMATION 

We are organized into two operating segments: Commercial Lasers and Components (“CLC”) and Specialty Lasers 

and Systems (“SLS”). This segmentation reflects the go-to-market strategies for various products and markets. While both 
segments work to deliver cost-effective photonics solutions, 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 OEM 
components and instrumentation and materials processing. SLS develops and manufacturers configurable, 
advanced-performance products largely serving the microelectronics and scientific research 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. 

We have identified CLC and SLS as operating segments for which discrete financial information was available. 

Both units have engineering, marketing, product business management and product line management. 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. 

Effective as of the beginning of the first quarter of fiscal 2009, in order to align all of our diode-pumped solid state 

(“DPSS”) technology into the same reportable operating segment, management moved the DPSS Germany and Crystal 
product families from the CLC segment into the SLS segment. This allows for leverage and efficiencies in many parts of the 
business. Crystal is primarily an internal supplier that supports the DPSS product family. This concentrates all DPSS product 
families in the SLS segment effective as of the first quarter of fiscal 2009. All reporting has been aligned to reflect the revised 
reportable operating segments (CLC and SLS) and prior periods have been restated. 

FINANCIAL INFORMATION ABOUT FOREIGN AND DOMESTIC OPERATIONS AND EXPORT SALES 

Financial information relating to foreign and domestic operations for fiscal years 2010, 2009 and 2008, is set forth in 

Note 18, “Segment and Geographic Information” of our Notes to Consolidated Financial Statements. 

ITEM 1A.  RISK FACTORS 

BUSINESS ENVIRONMENT AND INDUSTRY TRENDS 

Risks Associated with Our Industry, Our Business and Market Conditions 

Our operating results, including net sales, net income (loss) and adjusted EBITDA percentage 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 will 
continue to be subject to quarterly and annual fluctuations based upon numerous factors, including those listed in this 
section and throughout this report. Our stock price will continue to be subject to daily variations as well. In addition, 
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 has 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: 

• 

• 

• 

• 

• 

• 

general economic uncertainties in the macroeconomic and local economies facing us, our customers and the 
markets we serve; 

access to applicable credit markets by us, our customers and their end customers; 

fluctuations in demand for our products or downturns in the industries that we serve; 

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; 

timing or cancellation of customer orders and shipment scheduling; 

fluctuations in our product mix;

currency fluctuations; 

commodity pricing; 

introductions of new products and product enhancements by our competitors, entry of new competitors into our 
markets, pricing pressures and other competitive factors; 

our ability to develop, introduce, manufacture and ship new and enhanced products in a timely manner without 
defects; 

our ability to manage our capacity and that of our suppliers; 

our increased reliance on domestic and foreign contract manufacturing; 

delay of achievement of our footprint consolidation effort; 

the rate of market acceptance of our new products; 

the ability of our customers to pay for our products; 

expenses associated with acquisition-related activities; 

seasonal sales trends; 

delays or reductions in customer purchases of our products in anticipation of the introduction of new and 
enhanced products by us or our competitors; 

our ability to control expenses; 

the level of capital spending of our customers; 

potential excess and/or obsolescence of our inventory; 

costs and timing of adhering to current and developing governmental regulations and reviews relating to our 
products and business; 

costs related to acquisitions of technology or businesses; 

impairment of goodwill, intangible assets and other long term assets; 

our ability to meet our expectations and forecasts and those of public market analysts and investors; 

costs and expenses from litigation; 

the availability of research funding by the United States and foreign governments with regard to our customers 
in the scientific business, such as universities; 

continued spending by the United States government on defense-related projects where we are a subcontractor; 

government support of the alternative energy industries, such as solar; 

•  maintenance of supply relating to products sold to the government on terms which we would prefer not to 

accept; 

• 

changes in policy, interpretations, or challenges to the allowability of costs incurred under government cost 
accounting standards; 

17 
• 

the future impact of legislation, rulemaking, and changes in accounting, tax, defense procurement, or export 
policies; and 

• 

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, 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, the stock market 
has experienced extreme price and volume fluctuations that have affected the stock prices of many technology companies. 
There has not always been a direct correlation between this volatility and the performance of particular companies subject to 
these stock price fluctuations. Further, over the last twelve months, equity markets around the world have significantly 
fluctuated across most sectors. These factors, as well as general economic and political conditions or 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 are exposed to risks associated with worldwide economic conditions and related uncertainties. 

Volatility and disruption in the capital and credit markets, depressed consumer confidence, 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 has a significant 
impact on our results and, where such spending is delayed or canceled, it could cause a material negative impact on our 
operating results. The current global economic conditions remain uncertain and challenging. Weakness in our end markets 
could negatively impact our revenue, gross margin and operating expenses, and consequently have a material adverse effect 
on our business, financial condition and results of operations. 

The recent financial turmoil affecting the banking system and financial markets and the possibility that additional 
financial institutions may consolidate or go out of business have resulted in continued tightening in the credit markets, and 
lower levels of liquidity in some financial markets. There could be a number of follow-on effects from the 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 and terrorist acts may put further pressure 

on economic conditions in the United States and abroad. 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, thus fostering an atmosphere of greater potential exposure for 
inappropriate business conduct. See “Part I, Item 4. CONTROLS AND PROCEDURES—Inherent Limitations over Internal 
Control.” 

18 
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 affect on our ability to timely access funds. 

World capital and credit markets have been and continue to experience extreme 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, 
we may need to increase our 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. 

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, which results in corresponding 
pressure on the valuation of the securities issued by such nations. Additionally, our overall investment portfolio is often 
concentrated in certificates of deposit and money market funds. We maintain a certain mix of government-issued securities. 
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 and result in a material impairment, which could have a material 
adverse effect on our financial condition and operating results. See “Item 7A. Quantitative and Qualitative Disclosures about 
Market Risk.” 

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 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. We recorded a material charge during the first quarter of fiscal 2009 related to 
the impairment of goodwill in our CLC operating segment. 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 sole source or limited source suppliers, both internal and external, for some of our key components and 
materials, including exotic materials and crystals, in our products, which make us susceptible to supply shortages or price 
fluctuations that could adversely affect our business. 

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. 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. 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. 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. 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. Additionally, we continue to consolidate 
our supply base or 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. 

19 
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. Because we manufacture, package and test these 
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. 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. 

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 therefore, 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. 

We have historically been the photonics industry’s high quality supplier of laser systems. 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 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. 

During fiscal years 2010, 2009 and 2008, our research and development expenses have been in the range of 12% to 

14% of net sales. 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 2010, fiscal 2009 and fiscal 2008, 67%, 66% and 68%, respectively, of our net sales were derived from 
customers outside of the United States. We anticipate that foreign sales, particularly in Asia, will continue to account for a 
significant portion of our revenues in the foreseeable future. A global economic slowdown could have a negative effect on 
various foreign markets in which we operate. 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 resellers. Our foreign operations and 
sales are subject to a number of risks, including: 

20 
• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

longer accounts receivable collection periods; 

the impact of recessions and other economic conditions in economies outside the United States; 

unexpected changes in regulatory requirements; 

certification requirements; 

environmental regulations; 

reduced protection for intellectual property rights in some countries; 

potentially adverse tax consequences; 

political and economic instability; 

import/export regulations, tariffs and trade barriers; 

cultural and management differences; 

preference for locally produced products; and 

impairment of our shipping and other logistics. 

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 or cause customer order cancellations. 

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. We cannot assure you that our patent applications will be approved, that any patents that may be issued will 
protect our intellectual property or that any issued patents will not 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. 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 involving patents and other intellectual 

property rights. This has also been seen in our industry as well, for example in the litigation brought by IMRA America, Inc. 
against IPG Photonics Corporation. 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 

21 
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: 

• 

• 

stop manufacturing, selling or using our products that use the infringed intellectual property; 

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 

• 

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 for which we do not have insurance and our business may be seriously harmed. We do not have insurance 
to cover potential claims of this type. 

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 maintain customary levels of 
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 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, which 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 revenues. 

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 customer’s 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 revenue to offset such expenses. 

22 
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, Cymer, Inc., GSI Group, Inc., IPG Photonics 
Corporation, JDS Uniphase Corporation, Newport Corporation, Rofin-Sinar Technologies, 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 
competitors 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. 

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 revenues. 

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, 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 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 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: 

• 

• 

• 

• 

• 

• 

loss of customers; 

increased costs of product returns and warranty expenses; 

damage to our brand reputation; 

failure to attract new customers or achieve market acceptance; 

diversion of development and engineering resources; and 

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. 

23 
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 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 increased reliance on contract manufacturing and other 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. 
Additionally, we have outsourced the manufacture of certain of our optics components to a third party. 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 footprint consolidation effort, our business could be disrupted, which could harm our 
operating results. 

We have previously announced our intent to reduce our global operating footprint. If we are not able to effectively 
and timely transition the activities from one site to another or effectively close these facilities (including the manufacture of 
any applicable increased safety stock) there could be an adverse impact on our results of operations. 

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

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, 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: 

• 

issue stock that would dilute our current stockholders’ percentage ownership; 

24 
• 

• 

• 

• 

pay cash that would decrease our working capital; 

incur debt; 

assume liabilities; or 

incur expenses related to impairment of goodwill and amortization. 

Acquisitions also involve numerous risks, including: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

problems combining the acquired operations, systems, technologies or products; 

an inability to realize expected operating efficiencies or product integration benefits; 

difficulties in coordinating and integrating geographically separated personnel, organizations, systems and 
facilities; 

difficulties integrating business cultures; 

unanticipated costs or liabilities, including the costs associated with improving the internal controls of the 
acquired company; 

diversion of management’s attention from our core businesses; 

adverse effects on existing business relationships with suppliers and customers; 

potential loss of key employees, particularly those of the purchased organizations; 

incurring unforeseen obligations or liabilities in connection with acquisitions; and 

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 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. 

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 Tampere, Finland or our Sunnyvale, California sites 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 

25 
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, 
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 not currently aware of 
any such material costs or expenses. 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. 

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

Our operations, logistics and facilities and those of our suppliers and contract manufacturers could be subject to a 

catastrophic loss from fire, flood, earthquake, volcanic eruption, work stoppages, 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 revenue 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. 

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: 

• 

• 

• 

the ability of our Board of Directors to alter our bylaws without stockholder approval; 

limiting the ability of stockholders to call special meetings; and 

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 acquirors or result in a lower stock price. 

26 
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 worldwide tax liabilities. Our future tax rates could be affected by changes in 
the composition of earnings in countries or states with differing tax rates, changes in the valuation of our deferred tax assets 
and liabilities, or changes in the tax laws. In addition, we are subject to regular examination of our income tax returns and 
other tax-related filings 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 the recent announcement 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. 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 other tax-related accruals, which could materially and adversely affect our 
operating results and financial condition. 

Compliance with changing regulation of 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 
revenues. 

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 
revenues. From time to time our duty calculations and payments are audited by government agencies. For example, after our 
fiscal 2010 year-end, we received notice that the United States Customs and Border Protection Agency will be performing an 
audit on the classification and valuation of certain of our imported goods for purposes of duty calculation. We believe that we 
have complied with the applicable classification and valuation requirements. In the event any government agency disagrees 
with our determination of product values or classifications, we could be required to pay additional duties on such products, 
which could have an adverse effect on our operating results. 

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. 

27 
We may experience difficulties with our enterprise resource planning (“ERP”) system and other IT systems. System 
failure or malfunctioning may result in disruption of operations and the inability to process transactions, and this could 
adversely affect our ability to timely or accurately provide our financial results. 

System failure or malfunctioning could disrupt our ability to timely and accurately process and report key 
components of our results of operations, financial position and cash flows. Any disruptions or difficulties that may occur in 
connection with our ERP system or other systems could also adversely affect our ability to complete important business 
processes such as the evaluation of our internal controls and attestation activities pursuant to Section 404 of the 
Sarbanes-Oxley Act of 2002. If we encounter unforeseen problems with regard to our ERP system or other systems, our 
business and resulting financial reporting could be adversely affected. 

If our security measures are breached and unauthorized access is obtained to a customer’s data or our data, our service 
may be perceived as not being secure, customers may curtail or stop using our service and we may incur significant legal 
and financial exposure and liabilities. 

Our operations include the storage of customers’ proprietary information, and security breaches could expose us to a 
risk of loss of this information, litigation and possible liability. If our security measures are breached as a result of third-party 
action, employee error, malfeasance or otherwise, and, as a result, someone obtains unauthorized access to our data or our 
customers’ data, our reputation could be damaged, our business may suffer and we could incur significant liability. 
Additionally, third parties may attempt to fraudulently induce employees or customers into disclosing sensitive information 
such as user names, passwords or other information in order to gain access to our data or our customers’ data, which could 
result in significant legal and financial exposure and a loss of confidence in the security of our service that would harm our 
future business prospects. 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. If an actual or perceived breach of our security occurs, the market 
perception of the effectiveness of our security measures could be harmed and we could lose sales and customers. 

We employ technology licensed from third parties for use in or with our solutions, and the loss or inability to maintain 
these licenses or errors in the software we license could result in increased costs, or reduced service levels, which would 
adversely affect our business. 

Our hosted solutions incorporate certain technology obtained under licenses from other companies, such as Oracle 

and Salesforce.com. We anticipate that we will continue to license technology and development tools from third parties in the 
future. Although we believe that there are commercially reasonable software alternatives to the third-party software we 
currently license, this may not always be the case, or we may license third-party software that is more difficult or costly to 
replace than the third party software we currently license. In addition, integration of our products with new third-party 
software may require significant work and require substantial allocation of our time and resources. Also, to the extent that our 
products depend upon the successful operation of third-party products in conjunction with our products, any undetected 
errors in these third-party products could prevent the implementation or impair the functionality of our products, delay new 
product introductions and injure our reputation. Our use of additional or alternative third-party software would require us to 
enter into license agreements with third parties, which could result in higher costs. 

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 revenues in 
this industry will depend on, among other things: 

•  maintaining and enhancing our relationships with our customers; 

• 

• 

the education of potential end-user customers about the benefits of lasers and laser systems; and 

our ability to accurately predict and develop our products to meet industry standards. 

28 
For our fiscal years 2010, 2009 and 2008, our research and development costs were $72.4 million (12.0% of net 

sales), $61.4 million (14.1% of net sales) and $74.3 million (12.4% 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 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 (particularly in the semiconductor industry), 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. 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. 

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

A portion of our net sales in the microelectronics market depend on the demand for our products by semiconductor 

equipment companies. The semiconductor market has 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 this market severely limits our 
ability to predict our business prospects or financial results in this market. 

During industry downturns, our revenues from this market 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 this market, 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 this market 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. 

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 the Company’s 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.

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. The outcome of any 
such matters is currently not determinable. Although we do not expect that such legal claims and litigation will ultimately 
have a material adverse effect on our consolidated financial position or results of operations, an adverse result in one or more 
matters could negatively affect our results in the period in which they occur. 

Derivative Lawsuits 

Between February 15, 2007 and March 2, 2007, three purported shareholder derivative lawsuits were filed in the 

United States District Court for the Northern District of California against certain of the Company’s current and former 
officers and directors. The Company is named as a nominal defendant. The complaints generally allege that the defendants 
breached their fiduciary duties and violated the securities laws in connection with the granting of stock options, the 
accounting treatment for such grants, the issuance of allegedly misleading public statements and stock sales by certain of the 
individual defendants. On May 30, 2007, these lawsuits were consolidated under the caption In re Coherent, Inc. Shareholder 
Derivative Litigation, Lead Case No. C-07-0955-JF (N.D. Cal.). On June 25, 2007, plaintiffs filed an amended consolidated 
complaint. The consolidated complaint asserts causes of action for alleged violations of federal securities laws, violations of 
California securities laws, breaches of fiduciary duty and/or aiding and abetting breaches of fiduciary duty, abuse of control, 
gross mismanagement, constructive fraud, corporate waste, unjust enrichment, insider selling and misappropriation of 
information. The consolidated complaint seeks, among other relief, disgorgement and damages in an unspecified amount, an 
accounting, rescission of allegedly improper stock option grants, punitive damages and attorneys’ fees and costs. 

The Company’s Board of Directors appointed a Special Litigation Committee (“SLC”) comprised of independent 

director Sandeep Vij to investigate and evaluate the claims asserted in the derivative litigation and to determine what 
action(s) should be taken with respect to the derivative litigation. On September 8, 2009, Coherent, Inc., by and through the 
SLC, plaintiffs, and certain of Coherent’s former and current officers and directors filed with the court a Stipulation of 
Settlement reflecting the terms of a settlement that would resolve all claims alleged in the consolidated complaint. The terms 
of the settlement include a financial benefit to Coherent of over $6 million, which is comprised of a cash payment of 
$5.25 million to the Company and the waiver by certain former officers and directors of potential claims relating to expired 
stock options valued at $762,305. The settlement terms also include the implementation and/or agreement to maintain certain 
corporate governance changes, and a payment by the Company to plaintiffs’ counsel of $3 million in attorneys’ fees and 
expenses. 

On September 14, 2009, the United States District Court for the Northern District of California issued an order 

granting preliminary approval of the settlement. On November 20, 2009, the court held a hearing for final approval of the 
settlement, and on November 24, 2009, the court entered an Order and Final Judgment, which approved the settlement and 
dismissed the action with prejudice. Coherent received the cash payment of $2.25 million on December 11, 2009. 

Income Tax Audits 

The Internal Revenue Service (“IRS”) has reviewed and accepted the examination report for the audits of our 2003 

and 2004 U.S. federal income tax returns and this matter is now closed. We had previously agreed to various adjustments 
proposed by the IRS in its Notices of Proposed Adjustments (“NOPAs”) to these returns and there were no additional 
adjustments prior to the IRS concluding the audits and accepting the examination report. The IRS has indicated that it may 
consider an audit of our 2005 and 2006 tax returns. The IRS is also auditing the research and development credits generated 
in the years 1999 through 2001 and carried forward to future tax years. We received a NOPA from the IRS in October 2008 
to decrease the amount of research and development credits generated in years 2000 and 2001. We responded to this NOPA 
and we are disputing the adjustment with the IRS through the appeals process available to us and we have an opening 
conference scheduled in December 2010. We believe that we have provided adequate reserves for any adjustments related to 
these credits that may be determined under the IRS appeals process and therefore we do not anticipate any material impact to 
our financial statements. 

In the third quarter of fiscal 2010, the German tax authorities had concluded the audit of our subsidiary in Göttingen 
for the tax years 1999 through 2001. As a result of the audit settlement, there was a release of income tax reserves under ASC 
740, “Income Taxes,” (formerly FIN 48) net of the tax audit assessment and the amount was not material. After fiscal 
2010 year-end, the German tax authorities also concluded and issued an assessment for the audit of this subsidiary for the tax 
years 2002 through 2005. Since the written tax audit assessment was received after fiscal 2010 year-end, there was no 
adjustment to the ASC 740 net tax reserves in fiscal 2010. The reserve will be released in fiscal year 2011 and the impact of 
the net tax expense will not be material.

The number of stockholders of record as of December 1, 2010 was 1,190. No cash dividends have been declared or 

paid since Coherent was founded and we have no present intention to declare or pay cash dividends. 

On April 29, 2010, we announced that the Board of Directors had authorized the repurchase of up to $50 million of 

our common stock. During the year ended October 2, 2010, we repurchased and retired 1,195,919 shares of outstanding 
common stock at an average price of $36.21 per share for a total of $43.3 million, excluding expenses. Such repurchases 
were accounted for as a reduction in additional paid in capital. At October 2, 2010, $6.7 million remains authorized for 
repurchase under our current stock repurchase program. The timing and size of any purchases will be subject to market 
conditions. The program is authorized for 12 months. 

In February 2008, the Board of Directors authorized the Company to repurchase up to $225 million of its common 

stock through a modified “Dutch Auction” tender offer and an additional $25 million of its common stock, following the 
completion or termination of the tender offer, under its stock repurchase program, terminating no later than February 11, 
2009. On March 17, 2008, we completed our tender offer, repurchased and retired 7,972,313 shares of outstanding common 
stock for a total of $228.2 million. The repurchases were accounted for as a reduction in additional paid in capital.

Condensa building in Santa Clara, California, and a $0.7 million after-tax gain from the sale of substantially all of 
the net assets of our Coherent Imaging Optics Limited (COIL) subsidiary to CVI Laser. 

Includes a $11.7 million tax benefit primarily resulting from the consolidation of two wholly owned Japanese 
entities in which the income of one of the Japanese subsidiaries and a portion of the income of its German parent 
that were previously treated as permanently reinvested were deemed distributed to the U.S. and the income and the 
associated tax credits were reported for U.S. tax purposes, a $3.5 million after-tax charge for acquisition related 
costs from the terminated merger agreement with Excel, an additional $1.5 million after tax in purchase price and 
related legal and other fees associated with the acquisition of the remaining interest of our Lambda Physik 
subsidiary, $0.6 million after-tax Excel pre-merger integration related costs, a facility closure charge of $0.4 million 
after tax and an after tax IPR&D charge of $0.4 million associated with the purchase of the assets of Iolon in the first 
quarter of fiscal 2006.

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 “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.”

Definitions and analysis of these performance indicators are as follows: 

Bookings and Book-to-Bill Ratio 

Bookings represent orders expected to be shipped within 12 months and services to be provided pursuant to service 

contracts. While we generally have not experienced a significant rate of cancellation, bookings are generally cancelable 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, with a ratio greater than 1.0 indicating that demand is for our products is greater than what we 
supply in the year. 

Fiscal 2010 bookings reached a new record. Bookings increased 66.0% from fiscal 2009, with increases in all four 
markets led by a significant increase in the microelectronics market. Bookings increases by market compared to fiscal 2009 
were microelectronics (140%), materials processing (69%), OEM components and instrumentation (51%) and scientific 
(10%). 

Fiscal 2009 bookings were weak, decreasing 29.4% from fiscal 2008, particularly in the microelectronics and OEM 
components and instrumentation markets that were most impacted by the decline in consumer confidence and spending. As a 
result of the macroeconomic conditions in fiscal 2009, three of our markets experienced significant declines in bookings for 
the full fiscal year when compared to fiscal 2008: microelectronics (43%), materials processing (38%) and OEM components 
and instrumentation (35%). Scientific bookings increased 6% from fiscal 2008 to fiscal 2009. 

Microelectronics 

Record-setting bookings in fiscal 2010 increased 140% from fiscal 2009 and the book-to-bill ratio for the year was 

1.26. 

35 
 
 
 
Of the markets that we participate in, none gets more attention from analysts and investors than semiconductor 

capital equipment even though it represents only a modest portion of our overall business. Our business in fiscal 2011 should 
be resilient due to prior design wins with a number of key customers that have signaled stable capital equipment spending for 
advanced node logic and memory applications. We are investing in new technologies that will support higher resolution, 
better throughput and enhanced yields. 

There are several trends that will define the advanced packaging market for fiscal 2011, including the continued 

proliferation of mobile and tablet devices, accelerated migration towards laser-based direct imaging and via drilling systems 
and continued penetration of light-emitting diode (LED) devices for high-end displays. The growth outlook for mobile 
handsets and a projected increase in the number of tablets in 2011 bode well for our business in this market. One area that 
should benefit are lasers used in circuit board manufacturing, either for patterning through laser direct imaging or via drilling 
for high density interconnects. In 2010, we saw significant growth in lasers used for LED manufacturing. And while fab 
buildouts are continuing, the current glut in older generation LCD panel inventories has caused the market to pause. We 
anticipate that price incentives going into calendar year-end will clear the inventory and growth will return in the first half of 
calendar 2011. 

We took advantage of flat panel display manufacturing opportunities in the fourth quarter of fiscal 2010 with a 

multi-unit order for LCD annealing systems for mobile and tablet displays and significant orders for lasers used in light guide 
plate manufacturing for LED-based displays. We have recently received a multi-unit order for OLED manufacturing totaling 
approximately $37 million. The order was largely for Vyper™ lasers, our most advanced excimer light source, and line beam 
optics. All systems covered by this order are scheduled to ship within fiscal 2011. 

Growing pains persist in the solar market as most crystalline silicon manufacturers run at high capacity, but face 

dropping module prices. Interest remains high in techniques that improve efficiency and decrease cost. We are working with 
multiple customers on doping applications with many of them describing their work at the recent solar show in Valencia, 
Spain. 

OEM Components and Instrumentation 

Bookings in fiscal 2010 increased 51% from fiscal 2009 and the book- to-bill ratio for the year was 1.09. Orders of 

$165.3 million in the fourth quarter of fiscal 2010 set a new quarterly record. 

We received a number of large and/or annual orders in the fourth quarter of fiscal 2010, which we interpret as 

confidence in the midterm business outlook. While all geographies contributed, our OEM customers have highlighted the 
rising importance of Asian customers to their business. This is consistent with developing economies and growing 
discretionary income that can be applied to aesthetic or vision correction procedures. We have seen similar trends in the 
diagnostic market. 

Within in the product families, our OPS™ platform is doing well, especially within bioinstrumentation where form, 
function and reliability are critical. Demand for Existar™ excimer lasers used in refractive surgery is reflecting global trends 
including Asia. In addition, the machine vision business, whose products we acquired in the first quarter fiscal 2010 from 
StockerYale has shown solid demand. 

Materials Processing 

Although annual bookings increased significantly (69%) from fiscal 2009 and fiscal 2010’s book-to-bill ratio was 

1.10, bookings in the fourth quarter of fiscal 2010 decreased from the third quarter of fiscal 2010 due to the timing of several 
larger orders rather than a change in market sentiment, and seasonal softness in China that was offset by gains in Europe. The 
mix of low power applications and technologies remains relatively consistent with prior quarters. 

Orders increased for high power products such as the E-1000 CO2 laser and direct diode modules for use in cutting, 
welding and cladding. The development of our high power fiber laser product remains on track. We have completed several 
important program milestones including cutting metals with market-competitive speed and quality. 

The laser tools business is tracking to expectations and, at the same time, is providing an interesting contrast to the 

laser OEM business. The most notable differences are the amount of content we deliver and our involvement in process 
development. The end user and laser OEM customer response has been positive, so we see limited risk to stand-alone laser 
sales. The response at tradeshows has been strong. 

36 
Scientific and Government Programs 

Record-setting bookings in fiscal 2010 increased 10% from fiscal 2009 and the book-to-bill ratio for the year was 

1.05. 

The high order rate reflected pent-up demand from the third quarter of fiscal 2010 as well as lingering American 
Recovery and Reinvestment Act of 2009 (ARRA) funds in the United States. On the product front, we recognized record 
orders for Chameleon™ lasers for biological imaging applications and ultrafast amplifier systems for use in chemistry, 
physics and materials science research. We are also pleased with the acceptance of our OPS™ platform as a pump source for 
a growing number of applications. For the full year, we benefitted from stimulus funding in the U.S. and abroad and share 
gains, particularly in Asia. We estimate that ARRA contributed between $7 and $10 million in bookings. 

Net Sales 

Net sales include sales of lasers, laser tools, related accessories and service contracts. Net sales for fiscal 2010 

increased 38.8% from fiscal 2009. Net sales for fiscal 2009 decreased 27.3% from fiscal 2008. For a more complete 
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 CLC increased to 36.2% in fiscal 2010 from 26.4% in fiscal 
2009 and decreased from 39.8% in fiscal 2008. Gross profit percentage for SLS increased to 47.0% in fiscal 2010 from 
41.4% in fiscal 2009 and 43.7% in fiscal 2008. For a more complete 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 12.0% from 14.1% in fiscal 2009 and 12.4% in fiscal 2008. R&D percentage decreased primarily due to higher 
sales volumes, partially offset by higher project development spending. For a more complete 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 is 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 more complete 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 
2010 increased 4.3 days from fiscal 2009 to 65.6 days. The increase in DSO in receivables is primarily due to slower 
collections, particularly in Japan, and a higher concentration of sales in the fourth quarter. 

37 
Annualized Inventory Turns 

We calculate annualized 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 inventory turns for fiscal 2010 increased 
0.5 days from fiscal 2009 to 3.4 days. The improvement in inventory turns is primarily due to higher revenues in fiscal 2010 
compared to fiscal 2009 and efforts to control inventories such as site consolidations, increases in outsourcing and other 
inventory reduction programs. 

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. Management monitors capital spending levels as this assists 
management in measuring our cash flows, net of capital expenditures. Our capital spending percentage decreased from 5.0% 
in fiscal 2009 to 2.5% in fiscal 2010 and increased from 3.8% in fiscal 2008 to 5.0% in fiscal 2009. The fiscal 2010 decrease 
was primarily due to higher sales volumes in fiscal 2010 net of fiscal 2009 spending for the purchase of assets in support of a 
more effective business model for our semiconductor business and building investments related to our facilities consolidation 
and relocation programs. The fiscal 2009 increase was primarily due to lower revenues in fiscal 2009 as well as the purchase 
of assets in support of a more effective business model for our semiconductor business and building investments related to 
our facilities consolidation and relocation programs. We expect capital spending for fiscal 2011 to be approximately 4% of 
net sales. 

SIGNIFICANT EVENTS 

On February 12, 2008, the Company announced that the Board of Directors had authorized the Company to 

repurchase up to $225 million of its common stock through a modified “Dutch Auction” tender offer and an additional 
$25 million of its common stock, following the completion or termination of the tender offer, under its stock repurchase 
program, terminating no later than February 11, 2009. On March 17, 2008, we completed our tender offer and repurchased 
and retired 7,972,313 shares of outstanding common stock at a price of $28.50 per share for a total of $228.2 million, 
including expenses. Such repurchases were accounted for as a reduction in additional paid in capital. 

Effective March 31, 2008, we entered into a $40 million unsecured revolving credit account with Union Bank of 

California, which, as amended, expires on March 31, 2012. Our Union Bank of California agreement is subject to covenants 
related to financial ratios and tangible net worth. 

On April 16, 2008, we announced that we entered into an agreement to sell certain assets of our Auburn Optics 

manufacturing operation to Research Electro-Optics, Inc. (“REO”), a privately held optics manufacturing and technology 
company. We also entered into a strategic supply agreement with REO. REO is providing optical manufacturing capabilities 
for us, including fabrication and coating of optical components. The transition of the optics manufacturing assets from 
Auburn to REO was substantially completed by the end of the second quarter of fiscal 2009. 

During the first quarter of fiscal 2009, our stock price declined substantially, which combined with expectations of 

declines in forecasted operating results due to the slowdown in the global economy, led us to conclude that a triggering event 
for review for potential goodwill impairment had occurred. Accordingly, as of December 27, 2008, we performed an interim 
goodwill impairment evaluation. The performance of this test is a two-step process. Management reviewed the results of the 
Step 1 analysis and concluded that a Step 2 analysis was required only for the CLC reporting unit. Our preliminary analysis 
indicated that the entire balance of the goodwill in the CLC reporting unit at that date was impaired and we recorded a non-
cash goodwill impairment charge of $19.3 million in the first quarter of fiscal 2009. The estimated fair value of our SLS 
reporting unit exceeded its carrying value so no further impairment analysis was required for this reporting unit. 

In fiscal 2009, we initiated the planning phase of a multiyear project, with a targeted completion date of September 
2010, to exit our epitaxial growth facility in Tampere, Finland and establish enhanced capabilities in Sunnyvale, California. 
We decided to delay the closure due to a significant increase in demand for our products manufactured in Finland and we 
currently anticipate exiting the facility in the third quarter of fiscal 2011. We completed the consolidation of the remainder of 
our Munich facility into our Göttingen site during third quarter of fiscal 2009. During the second quarter of fiscal 2009, we 
substantially completed the transition of our optics manufacturing assets from Auburn, California to REO, and announced 
that we would be exiting our facility in St. Louis, Missouri. We completed the exit from St. Louis, Missouri in the fourth 
quarter of fiscal 2009. 

38 
On October 13, 2009, we acquired all the assets and certain liabilities of StockerYale’s laser module product line in 

Montreal and its specialty fiber product line in Salem, New Hampshire for $15.0 million in cash. StockerYale designs, 
develops and manufactures low power laser modules, light emitting diode (LED) systems and specialty optical fiber products. 
These assets and liabilities have been included in our Commercial Lasers and Components segment. 

On April 29, 2010 we announced that our Board of Directors authorized the Company to repurchase up to 
$50 million of our common stock under a stock repurchase program. In the second half of fiscal 2010, we repurchased and 
retired 1,195,829 shares of outstanding common stock for a total of $43.3 million, excluding expenses. The timing and size of 
any future purchases will be subject to cash balances and general business and market conditions. The program is authorized 
for 12 months from the date of announcement. 

On April 29, 2010, we acquired Beam Dynamics for $6.25 million, excluding transaction fees. Beam Dynamics 

manufactures flexible laser cutting tools for the materials processing market. These assets and liabilities have been included 
in our Commercial Lasers and Components segment. 

On November 4, 2010, we announced that we entered into a definitive agreement to acquire the business assets of 

privately-held Hypertronics for approximately $15.0 million in an all cash transaction. The transaction is subject to a number 
of closing conditions and is expected to close during our second fiscal quarter of 2011. 

RESULTS OF OPERATIONS—FISCAL 2010, 2009 AND 2008 

Fiscal 2009 included 53 weeks; fiscal 2010 and 2008 included 52 weeks.

During fiscal 2010, net sales increased by $169.2 million, or 39%, compared to fiscal 2009, including an increase of 
$6.1 million due to the impact of foreign currency exchange rates, with sales increasing in all four markets. Microelectronics 
sales increased $98.6 million, or 75%, primarily due to higher sales in advanced packaging, flat panel display, semiconductor 
and solar applications. The increase in the OEM components and instrumentation market of $31.5 million, or 26%, during 
fiscal 2010 was primarily due to higher shipments for flow cytometry applications and for machine vision applications due to 
the acquisition of certain product lines from StockerYale in the first quarter of fiscal 2010. Materials processing sales 
increased $21.1 million, or 35%, during fiscal 2010 primarily due to higher shipments for marking applications. The increase 
in scientific and government program market sales of $18.0 million, or 15%, during fiscal 2010 was due to higher demand for 
advanced research applications used by university and government research groups in part due to Federal stimulus money. 

During fiscal 2009, net sales decreased by $163.4 million, or 27%, compared to fiscal 2008, including a decrease of 
$7.0 million due to the impact of foreign currency exchange rates, with sales decreasing in all four markets. Microelectronics 
sales decreased $74.1 million, or 36%, primarily due to lower sales in advanced packaging, flat panel display and 
semiconductor applications. A drop in consumer confidence and spending continued to impact this market negatively during 
fiscal 2009. The decrease in the OEM components and instrumentation market of $54.0 million, or 31%, during fiscal 2009 
was primarily due to reduced consumer spending for medical applications, decreased shipments for bioinstrumentation 
applications, lower shipments for military applications (primarily due to the sales of assets and outsourcing of our optics 
manufacturing) and lower shipments for graphic arts and display applications. Materials processing sales decreased 
$33.1 million, or 35%, during fiscal 2009 primarily due to lower laser shipments to customers providing consumer-based 
applications. The decrease in scientific and government program market sales of $2.1 million, or 2%, during fiscal 2009 was 
due to lower demand from university and government research groups. 

In fiscal 2010, 2009 and 2008, no customers accounted for greater than 10% of net sales. 

Segments 

We are organized into two reportable operating segments: Commercial Lasers and Components (“CLC”) and 
Specialty Lasers and Systems (“SLS”). CLC focuses on higher volume products that are offered in set configurations. CLC’s 
primary markets include OEM components and instrumentation and materials processing. SLS develops and manufacturers 
configurable, advanced-performance products largely serving the microelectronics and scientific research markets.

Net sales for fiscal 2010 increased $169.2 million, or 39%, compared to fiscal 2009, with increases of $86.1 million, 
or 28%, in our SLS segment and increases of $83.1 million, or 66%, in our CLC segment. Net sales for fiscal 2009 decreased 
$163.4 million, or 27%, compared to fiscal 2008, with decreases of $90.3 million, or 23%, in our SLS segment and decreases 
of $73.1 million, or 37%, in our CLC segment. 

The increase in our CLC segment sales from fiscal 2009 to fiscal 2010 was primarily due to higher advanced 

packaging, materials processing, flat panel display and instrumentation application sales. The decrease in our CLC segment 
sales from fiscal 2008 to fiscal 2009 was primarily due to lower sales in advanced packaging, materials processing and 
semiconductor applications sales. 

The increase in our SLS segment sales from fiscal 2009 to fiscal 2010 was primarily due to higher sales for 

advanced packaging, semiconductor, solar, scientific and flat panel display applications. The decrease in our SLS segment 
sales from fiscal 2008 to fiscal 2009 was primarily due to lower revenue for bio-instrumentation, medical, microelectronics 
and semiconductor applications. 

Gross Profit 

Consolidated 

Our gross profit rate increased by 6.1% to 43.1% in fiscal 2010 from 37.0% in fiscal 2009. The increase in the gross 
profit rate was primarily due to higher sales volumes and a lower manufacturing cost structure as well as lower restructuring 
costs. The improvement includes lower other costs primarily due to lower need for inventory provisions for excess and 
obsolete items (2.3%), the benefit of a lower manufacturing cost structure (1.8%), lower restructuring costs (1.4%) and lower 
warranty and installation costs (0.7%) due to the benefit of increasing volumes net of the cost resulting from replacement of 
non-compliant vendor components. 

Our gross profit rate decreased by 5.0% to 37.0% in fiscal 2009 from 42.0% in fiscal 2008. The decrease in the gross 

profit rate was primarily due to higher other costs (1.8%) due to the need for higher inventory provisions and the impact of 
lower sales volumes, unfavorable impact of fixed manufacturing costs on lower sales volumes net of the benefit of a 
weakened Euro and favorable product mix in the instrumentation market partially offset by the less favorable 
microelectronics market mix (1.8%) and the incremental impact of restructuring activities (1.5%) partially offset by lower 
stock-based compensation expense (0.2%). 

Our gross profit rate has been and will continue to be affected by a variety of factors including market mix, 
manufacturing efficiencies, excess and obsolete inventory write-downs, warranty costs, pricing by competitors or suppliers, 
new product introductions, production volume, customization and reconfiguration of systems, commodity prices and foreign 
currency fluctuations. 

Commercial Lasers and Components 

Our CLC gross profit rate increased by 9.8% to 36.2% in fiscal 2010 from 26.4% in fiscal 2009. The increase in 

gross profit rate was primarily due to lower other costs (4.3%) primarily due to lower need for inventory provisions and the 
impact of higher sales volumes, lower restructuring costs (1.9%), the impact of increased volumes and cost reduction efforts 
(1.9%) and lower warranty and installation costs (1.6%) due to the benefit of increasing volumes net of the cost resulting 
from replacement of non-compliant vendor components. 

41 
 
 
 
Our CLC gross profit rate decreased by 13.4% to 26.4% in fiscal 2009 from 39.8% in fiscal 2008. The decrease in 

gross profit rate was primarily due to higher product costs primarily due to the impact of lower volumes and unfavorable 
product mix with a higher proportion of net sales in lower margin markets (6.5%), higher other costs (3.3%) due to the need 
for higher inventory provisions, the incremental impact of restructuring activities (2.8%) and higher warranty and installation 
costs (0.8%). 

Specialty Lasers and Systems 

Our SLS gross profit rate increased by 5.6% to 47.0% in fiscal 2010 from 41.4% in fiscal 2009. The increase in 

gross profit rate was primarily due to the impact of increased volumes and cost reduction efforts as well as favorable product 
mix in the microelectronics and solar markets (2.5%), lower other costs (1.7%) due to lower need for inventory provisions 
and the impact of higher sales volumes and lower restructuring costs (1.3%). Although warranty and installation costs as a 
percentage of net sales were flat, the benefit of increasing volumes was offset by the cost resulting from replacement of non-
compliant vendor components. 

Our SLS gross profit rate decreased by 2.3% to 41.4% in fiscal 2009 from 43.7% in fiscal 2008. The decrease in 

gross profit rate was primarily due to higher other costs (1.3%) due to the need for higher inventory provisions and the impact 
of lower sales volumes, the incremental impact of restructuring activities (1.0%) and the impact of lower sales volumes net of 
a favorable product mix from the instrumentation market and less favorable mix from the microelectronics market and the 
benefit of a weakened Euro (0.2%) partially offset by lower warranty and installation costs (0.1%).

Research and development 

Fiscal 2010 research and development (“R&D”) expenses increased $10.9 million, or 18%, from fiscal 2009. The 

increase was primarily due to higher payroll spending ($4.2 million) due to higher performance-related compensation net of 
lower severance-related restructuring costs and the elimination of mandatory time off, higher project spending ($3.6 million), 
the acquisition of certain product lines from StockerYale in the first quarter of fiscal 2010 and Beam Dynamics in the third 
quarter of fiscal 2010 ($2.6 million), higher charges for increases in deferred compensation plan liabilities ($0.7 million) with 
the related earnings for increases in deferred compensation plan assets recorded in other income (expense), $0.3 million 
higher stock-based compensation expense and higher other spending ($0.2 million) partially offset by lower non-severance 
related restructuring costs ($0.7 million). 

Fiscal 2009 R&D expenses decreased $12.9 million, or 17%, from fiscal 2008. The decrease was primarily due to 

lower payroll and bonus spending including mandatory time off in fiscal 2009 and the impact of lower headcount 
($9.2 million), lower spending on projects ($4.3 million), the impact of foreign currency exchange rates ($2.1 million), lower 
stock-based compensation expense ($1.1 million) and a higher benefit due to decreases in deferred compensation plan 
liabilities ($0.5 million) with the related decreases in deferred compensation plan assets recorded in other income (expense), 
partially offset by lower net reimbursements from customers for development projects ($2.4 million) and higher restructuring 
costs ($1.9 million). On a segment basis, CLC spending decreased $6.2 million primarily due to lower project spending 
including lower payroll and bonus spending. SLS spending decreased $5.9 million primarily due to lower spending on 
projects, lower payroll and bonus spending and the impact of foreign currency exchange rates. Corporate and other spending 
decreased $0.8 million. 

42 
 
 
 
 
Selling, general and administrative 

Fiscal 2010 selling, general and administrative (“SG&A”) expenses increased $15.5 million, or 14%, from fiscal 

2009. The increase was primarily due to $11.0 million higher payroll spending due to higher performance-related 
compensation spending and the elimination of mandatory time off net of savings from site consolidations and other 
restructuring activities, $4.3 million higher charges due to increases in deferred compensation plan liabilities with the related 
earnings for increases in deferred compensation plan assets recorded in other income (expense), the acquisition of certain 
product lines from StockerYale ($2.8 million), higher other spending ($1.2 million), $0.9 million higher stock-based 
compensation expense and the impact of foreign currency exchange rates ($0.6 million) partially offset by $3.3 million lower 
costs incurred for litigation resulting from our internal stock option investigation primarily due to a receipt from the 
settlement of the litigation and $2.0 million lower spending on facilities due to site consolidations. On a segment basis, CLC 
spending increased $6.1 million primarily due to higher payroll spending and the acquisition of certain product lines from 
StockerYale. SLS segment expenses increased $3.0 million primarily due to higher payroll spending net of savings from site 
consolidations. Spending for Corporate and other increased $6.4 million primarily due to higher charges due to increases in 
deferred compensation plan liabilities and higher performance-related compensation spending partially offset by lower costs 
incurred for litigation resulting from our internal stock option investigation. 

Fiscal 2009 SG&A expenses decreased $38.3 million, or 26%, from fiscal 2008. The decrease was primarily due to 

$14.1 million lower payroll and bonus spending including the impact of lower headcount and mandatory time off in fiscal 
2009, $7.9 million lower costs related to our restatement of financial statements and litigation resulting from our internal 
stock option investigation, the impact of foreign currency exchange rates ($4.2 million), $3.8 million lower stock-based 
compensation expense, $2.7 million lower spending on depreciation and equipment, $2.7 million lower spending on travel, 
demo depreciation and advertising, $2.4 million lower spending on legal and other consulting, a higher benefit due to 
decreases in deferred compensation plan liabilities ($1.9 million) with the related decreases in deferred compensation plan 
assets recorded in other income (expense) and lower other spending ($0.7 million), partially offset by $2.1 million higher 
restructuring costs. On a segment basis, SLS SG&A expenses decreased $12.2 million and CLC SG&A expenses decreased 
$7.1 million, both primarily due to lower payroll and bonus spending, the impact of foreign currency exchange rates, lower 
depreciation and lower spending on travel and advertising. Corporate and other spending decreased $19.0 million primarily 
due to lower costs related to our restatement of financial statements and litigation resulting from our internal stock option 
investigation, lower stock-based compensation expense, a higher benefit due to decreases in deferred compensation plan 
liabilities, lower payroll and bonus spending and lower spending on legal and other consulting. 

Impairment of goodwill 

Under generally accepted accounting principles, goodwill is tested for impairment on an annual basis and between 

annual tests in certain circumstances, and written down when impaired. During the first quarter of fiscal 2009, our stock price 
declined substantially, which combined with expectations of declines in forecasted operating results due to the slowdown in 
the global economy, led the Company to conclude that a triggering event for review for potential goodwill impairment had 
occurred. Accordingly, as of December 27, 2008, we performed an interim goodwill impairment evaluation which indicated 
that the goodwill was fully impaired. We recorded a non-cash goodwill impairment charge of $19.3 million in the CLC 
reporting unit in the first quarter of fiscal 2009. 

Amortization of intangible assets 

Amortization of intangible assets increased $0.5 million, or 7%, from fiscal 2009 to fiscal 2010 primarily due to the 
acquisition of certain product lines from StockerYale and the acquisition of Beam Dynamics partially offset by completion of 
amortization of certain intangibles related to prior acquisitions. 

Amortization of intangible assets decreased $1.2 million, or 14%, from fiscal 2008 to fiscal 2009 primarily due to 

the completion of amortization of certain intangibles related to prior acquisitions. 

Other income (expense), net 

Other income (expense), net, increased $1.8 million from fiscal 2009 to fiscal 2010. The increase was primarily due 

to the recovery in the market value of our deferred compensation plan assets ($5.1 million) partially offset by lower benefit 
from Japan consumption tax savings ($2.5 million) as the benefit expired in the fourth quarter of fiscal 2009, lower interest 
income ($0.6 million) as a result of lower rates of return net of interest on tax refunds and the impact of higher average cash, 
cash equivalents and short-term investments balances and higher foreign currency exchange losses ($0.3 million). 

43 
Other income (expense), net, decreased $15.4 million from fiscal 2008 to fiscal 2009. The decrease was primarily 
due to lower interest income ($8.4 million) as a result of lower rates of return and lower average cash, cash equivalents and 
short-term investments balances, higher expense due to decreases in deferred compensation plan assets ($3.3 million) and 
higher foreign currency exchange losses ($3.1 million). 

Income taxes 

The effective tax rate on income before income taxes for fiscal 2010 of 36.3% was higher than the statutory rate of 
35.0%. This was primarily due to stock compensation not deductible for tax purposes and an increase in valuation allowance 
against capital loss carryforwards, California research and development tax credits as a result of California legislation enacted 
in February 2009 and certain foreign net operating loss carryforwards. These increases are partially offset by the benefit of 
income subject to foreign tax rates that are lower than U.S. tax rates and research and development credits. 

During fiscal 2010, we increased our valuation allowance on deferred tax assets by $0.6 million to $7.4 million, 
primarily due to a capital loss limitation true-up, the reduced ability to utilize California R&D tax credits as a result of the 
current apportionment factor and the reduced ability to utilize foreign net operating losses. During fiscal year 2009, we 
increased our valuation allowance on deferred tax assets to $6.8 million, primarily due to California R&D tax credits as a 
result of new California legislation and the reduced ability to utilize foreign net operating losses. During fiscal 2008, we 
decreased our valuation allowance on deferred tax assets to $1.7 million, primarily due to the expiration of federal and state 
capital loss carryforwards and the valuation allowance with respect to the loss from the disposal of our Auburn facility in 
California was also reduced with a corresponding increase in uncertain tax positions. 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. 

The “Worker, Homeownership and Business Assistance Act of 2009” was enacted on November 6, 2009. Under the 

Act, businesses with net operating losses for 2008 and 2009 may carry back those losses for up to five years. We elected to 
carry back the net operating loss generated in the tax year ended October 3, 2009 to the tax year ended September 30, 2006 
and we received a refund of $2.7 million. 

In September 2008, the state of California approved its budget which limited our ability to utilize available state net 

operating losses and tax credits. Under this tax law, the utilization of net operating losses was suspended for tax years 2008 
and 2009 and the expiration date of net operating loss carryforwards was extended for a two-year period. Additionally, for tax 
years 2008 and 2009, taxpayers may only utilize available tax credits to reduce 50% of their current tax liability. The new law 
does not affect the amount of net operating loss or tax credit carryforwards that we expect to ultimately use to offset future 
California taxes. However, it did limit the amount of net operating losses and tax credits that we were able to utilize to reduce 
our taxes payable for fiscal year 2010. This amount is not considered material. 

On October 8, 2010, the state of California approved its 2010-2011 budget that includes modifications to tax law 

provisions that were previously set to become effective with tax years beginning on or after January 1, 2011. We are 
assessing the effects of the change in the tax law and will recognize any impacts in fiscal year 2011. 

The difference between the statutory rate of 35.0% and our effective tax rate of 1.5% on income (loss) before 

income taxes for fiscal 2009, which represents a current year benefit, was due primarily to permanent differences related to 
the non-deductibility of the goodwill impairment charge, an increase in valuation allowance against California research and 
development tax credits as a result of California legislation enacted in February 2009 and certain foreign net operating loss 
carryforwards, and deemed dividend inclusions under the Subpart F tax rules. These amounts are partially offset by 
permanent differences related to the benefit of foreign tax credits and the benefit of federal research and development tax 
credits, including additional credits reinstated from fiscal 2008 resulting from the enactment of the “Emergency Economic 
Stabilization Act of 2008.” 

The effective tax rate on income before income taxes for fiscal 2008 of 37.2% was higher than the statutory rate of 

35.0%. This was primarily due to permanent differences related to foreign currency exchange gains on previously taxed 
income distributions from foreign subsidiaries and deemed dividend inclusions under the Subpart F rules, partially offset by 
the benefit of foreign tax credits and research and development tax credits.

FINANCIAL CONDITION 

Liquidity and capital resources 

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 option and purchase plans, as 
well as through debt borrowings. Our historical uses of cash have primarily been for the repurchase of our common stock, 
capital expenditures, acquisitions of businesses and technologies and payments of principal and interest on outstanding debt 
obligations. 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 increased by $39.8 million in fiscal 2010 compared to fiscal 2009 and 

decreased by $29.3 million in fiscal 2009 compared to fiscal 2008. The increase in cash provided by operating activities in 
fiscal 2010 was primarily due to higher net income and higher cash flows due to new tax legislation which allows the carry 
back of net operating losses for up to five years partially offset by lower cash flows from increased working capital (accounts 
receivable and inventories, net of increases in accounts payable and accrued expenses) needed to support increased sales and 
projected sales volumes. The decrease in cash provided by operating activities in fiscal 2009 was primarily due to lower net 
income and lower net cash flows from deferred income taxes partially offset by higher cash flows as a result of declining 
balances of inventories and accounts receivable. We believe that our existing cash, cash equivalents and short term 
investments combined with cash to be provided by operating activities 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 borrowings under our bank credit facilities or other sources of capital. We continue to 
follow our strategy to further strengthen our financial position by using available cash flow to fund operations. 

We intend to continue pursuing acquisition opportunities at valuations we believe are reasonable based upon market 

conditions as demonstrated by our acquisition of businesses from StockerYale in the first quarter of fiscal 2010 and Beam 
Dynamics in the third quarter of fiscal 2010 as well as the pending acquisition of the business assets of Hypertronics in the 
first quarter of fiscal 2011 (see Note 19 “Subsequent Events” in the Notes to Consolidated Financial Statements). 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 primarily through existing cash balances and cash flows from operations. If required, we 
will look for additional borrowings or 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 from time to time and the willingness of 
potential sellers to accept it as full or partial payment. 

On April 29, 2010, we announced that the Board of Directors had authorized us to repurchase up to $50 million of 

our common stock under our stock repurchase program. The program is authorized for 12 months. In fiscal 2010, we 
repurchased and retired 1,195,829 shares of outstanding common stock for a total of $43.3 million, excluding expenses. 

During fiscal year 2008, we initiated restructuring plans to decrease costs by consolidating facilities and reducing 
our workforce. As of October 2, 2010, we had made payments in connection with the restructuring plans in the amount of 
$25.2 million. We expect to complete payments for substantially all anticipated costs related to the restructuring plans by the 
third quarter of fiscal 2011. 

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

facilities totaling $56.1 million as of October 2, 2010, of which $54.1 million was unused and available. These credit 
facilities were used in Europe during fiscal 2010 as guarantees. Our domestic line of credit includes a $40 million unsecured 
revolving credit account with Union Bank of California, which expires on March 31, 2012 and is subject to covenants related 
to financial ratios and tangible net worth. No amounts have been drawn upon our domestic line of credit and $2.0 million has 
been used of the international currency lines as of October 2, 2010. 

45 
 
 
Our ratio of current assets to current liabilities was 4.1:1 at October 2, 2010, compared to 5.6:1 at October 3, 2009. 

The decrease in our ratio is primarily due to increases in other current liabilities and accounts payable. Our cash and cash 
equivalents, short-term investments, restricted cash, working capital and debt obligations are as follows (in thousands):

Contractual Obligations and Off-Balance Sheet Arrangements 

We have no off-balance sheet arrangements as defined by Regulation S-K of the Securities Act of 1933. The

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 $24.3 million at October 2, 2010. 

As of October 2, 2010, we recorded gross unrecognized tax benefits of $50.1 million and gross interest and penalties 

of $6.9 million. As of October 3, 2009, we recorded gross unrecognized tax benefits of $58.1 million and gross interest and 
penalties of $7.7 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 2010 was $78.8 million, which included net income of $36.9 million, 

depreciation and amortization of $29.7 million, increases in net deferred tax assets of $13.3 million, stock-based 
compensation expense of $8.3 million and non-cash restructuring charges of $4.3 million partially offset by cash used by 
operating assets and liabilities of $13.2 million and $0.5 million other. 

Cash used in investing activities in fiscal 2010 of $11.9 million included $20.7 million used to acquire certain assets 

of StockerYale and our acquisition of Beam Dynamics, $15.1 million used to acquire property and equipment and improve 
buildings, a $2 million investment in SiOnyx and a $0.6 million increase in restricted cash partially offset by $24.4 million of 
net proceeds from sales of available-for-sale securities and $2.1 million in proceeds from dispositions of property and 
equipment. 

Cash used in financing activities in fiscal 2010 was $10.2 million, including $43.3 million used to repurchase our 
common stock and $0.3 million other partially offset by $33.4 million generated from our employee stock purchase plans. 

46 
 
 
 
Changes in exchange rates in fiscal 2010 resulted in a decrease in cash balances of $11.3 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 vast majority of our sales are made to original equipment manufacturers (OEMs), distributors, resellers 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. 

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, resellers and end-user customers typically do not have customer acceptance provisions and 

only certain of our sales to OEM customers 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 by the customer’s acceptance of 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. 

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 

47 
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: CLC and SLS. 

Goodwill is tested for impairment on an annual basis and between annual tests in certain circumstances, and written 
down when impaired (see Note 8 “Goodwill and Intangible Assets” in the Notes to Consolidated Financial Statements). We 
perform our annual impairment tests at the beginning of 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. 

During the first quarter of fiscal 2009, our stock price declined substantially which, combined with expectations of 

declines in forecasted operating results due to the slowdown in the global economy, led the Company to conclude that a 
triggering event for review for potential goodwill impairment had occurred. Accordingly, as of December 27, 2008, we 
performed an interim goodwill impairment evaluation. Goodwill is tested for impairment by comparing the respective fair 
value with the respective carrying value of the reporting unit. If such comparison indicates a potential impairment, then the 
impairment is determined as the difference between the recorded value of goodwill and its fair value. The performance of this 
test is a two-step process. 

Step 1 of the impairment test involves comparing the fair values of the applicable reporting units with their 

aggregate carrying values, including goodwill. If the carrying amount of a reporting unit exceeds the reporting unit’s fair 
value, we perform Step 2 of the goodwill impairment test to determine the amount of impairment loss if any. Step 2 of the 
goodwill impairment test involves comparing the implied fair value of the affected reporting unit’s goodwill against the 
carrying value of that goodwill. 

We have historically relied on the Income approach to determine the fair value of our reporting units. In the first 

quarter of fiscal 2009, when we determined that a triggering event had occurred, we subsequently determined that it would be 
appropriate to rely on the following three valuation approaches to determine the fair value of both of our reporting units. 
(1) 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. (2) 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. (3) The Transaction approach estimates the fair value of the reporting unit based on 
market prices in actual transactions. A comparison is done between the reporting units and other similar businesses. Total 
Enterprise Value multiples for revenue and earnings as noted in the Market approach above are calculated from the 
comparable companies and then applied to the reporting unit’s operating results to obtain an estimate of fair value. Each of 
these three approaches captures aspects of value in each reporting unit. The Income approach captures our expected future 
performance, the Market approach captures how investors view the reporting units through other competitors; and, the 
Transaction approach captures value through transactions for sales of similar types of companies. We believe these valuation 
approaches are proven valuation techniques and methodologies for our industry and are widely accepted by investors. 

As none were perceived by us to deliver any greater indication of value than the other, we weighted each of the 

approaches equally. The sensitivity analysis performed by management determined that by changing the weighting placed on 
the three approaches, the result of the Step 1 test for both reporting units was not affected. 

The valuation analysis requires significant judgments and estimates to be made by management in particular related 
to the forecast. The assumed growth rates and gross margins as well as period expenses were determined based on internally 
developed forecasts considering our future plans. The assumptions used were management’s best estimates based on 
projected results and market conditions as of the date of testing. In order to test the sensitivity of these fair values, 
management further reviewed other scenarios relative to these assumptions to see if the resulting impact on fair values would 
have resulted in a different Step 1 conclusion for the CLC and SLS reporting units. 

48 
Based on these forecast scenarios, the fair value of both reporting units was re-calculated. In addition, this sensitivity 

analysis applied more conservative assumptions with regard to control premiums as well as multipliers used in the Market 
approach and the Transaction approach. In each of the sensitivity analyses performed, the CLC reporting unit failed and the 
SLS reporting unit passed. None of the outcomes of the sensitivity analyses performed would have impacted our Step 1 
conclusions or the non-cash impairment charge for goodwill of $19.3 million recorded in the first quarter of fiscal 2009. 

Sensitivity was also applied to the discount rate used in the Income approach for both the CLC and SLS reporting 
units. At December 27, 2008, the discount rate for the CLC reporting unit could have been reduced by more than 40% and 
still resulted in a failure. For the SLS reporting unit, the discount rate could have been increased by more than 40% and still 
resulted in no impairment. 

During the second quarter of fiscal 2009, our expectations of declines in forecasted operating results due to the 
slowdown in the global economy and the further declines in our stock price led us to conclude that a triggering event for 
review for potential goodwill impairment had occurred. Accordingly, as of April 4, 2009, we performed an interim goodwill 
impairment evaluation. This interim impairment evaluation utilized the same valuation techniques used in our impairment 
valuation in the first quarter of fiscal 2009. A similar sensitivity analysis was also done at April 4, 2009 where we determined 
that the discount rate used in the Income approach for the SLS reporting unit could have been increased by approximately 
20% and still resulted in no impairment. Based on the results of our Step 1 analysis, we determined that no additional 
goodwill impairment was indicated. 

During the third and fourth quarters of fiscal 2009, and the first three quarters of fiscal 2010, we noted no 

indications of impairment or triggering events to cause us to review goodwill for potential impairment. 

At October 2, 2010, we had $70.8 million of goodwill, $19.9 million of purchased intangible assets and 
$90.3 million of property and equipment on our consolidated balance sheet. We performed our annual goodwill impairment 
testing at the beginning of the fourth quarter using the opening balance sheet as of the first day of the fourth fiscal quarter and 
noted no impairment. As noted in the valuation analysis discussion above, such analysis requires significant judgments and 
estimates to be made by management in particular related to the forecast. The assumed growth rates and gross margins as 
well as period expenses were determined based on internally developed forecasts considering our future plans. The 
assumptions used were management’s best estimates based on projected results and market conditions as of the date of 
testing. Utilizing the Income Approach, we noted no impairment. Based on our evaluation, the fair values of each of the two 
operating segments significantly exceeded their carrying value. In order to test the sensitivity of these fair values, 
management further reviewed other scenarios relative to these assumptions to see if the resulting impact on fair values would 
have resulted in a different conclusion for the CLC and SLS reporting units. Sensitivity was applied to the discount rate used 
in the Income approach for both the CLC and SLS reporting units. The discount rate for the CLC and SLS reporting units 
could have been increased by more than 25% and still resulted in no impairment. Based on the outcome of this testing and 
sensitivity analysis, we decided it would not be necessary to utilize all three testing methods for this annual test. 

As no impairment indicators were present during the fourth quarter of fiscal 2010, we believe these values remain 

recoverable. 

It is reasonably possible that the estimates of anticipated future net revenue, the remaining estimated economic life 

of the products and technologies, or both, could differ from those used to assess the recoverability of these assets. In addition, 
if the price of our common stock were to significantly decrease combined with any other adverse change in market 
conditions, thus indicating that the underlying fair value of our reporting units or other long-lived assets may have decreased, 
we may be required to assess the recoverability of such assets in the period such circumstances are identified. In that event, 
additional impairment charges or shortened useful lives of certain long-lived assets may be required. Such testing was done 
on our long-lived assets and intangibles in the Step 1 testing discussed above, and no impairment was noted. 

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 and when individual parts have been in inventory for greater than 12 months. 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. 

49 
Warranty Reserves 

We provide warranties on certain 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 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 stock options granted using 

the Black-Scholes Merton 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 amortize the fair value of stock options on a 
straight-line basis over the requisite service periods of the awards, which are generally the vesting periods. We value 
restricted stock units using the intrinsic value method. We amortize the value of restricted stock units on a straight-line basis 
over the restriction period. 

U.S. 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 14 “Employee Stock Option 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. 

Federal income taxes have not been provided for 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 of foreign 
subsidiaries for which we have not yet recorded federal income taxes was approximately $129.4 million at fiscal 2010 year-
end. In addition to federal income taxes (which are not practicably determinable), withholding taxes of approximately 
$5.9 million would be payable upon repatriation of such earnings which would result in additional foreign tax credits. 

The “Worker, Homeownership and Business Assistance Act of 2009” was enacted on November 6, 2009. Under the 

Act, businesses with net operating losses for 2008 and 2009 may carry back those losses for up to five years. We elected to 
carry back the net operating loss generated in the tax year ended October 3, 2009 to the tax year ended September 30, 2006 
and we received a refund of $2.7 million.

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 market interest rates were to increase immediately and 
uniformly by 10% from levels at fiscal 2010 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. 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 2010 year-end, the fair value of our available-for-sale debt securities was $17.4 million, all of which was 

classified as short-term investments. Gross unrealized gains and losses on available-for-sale debt securities were $82,000 and 
($2,000), respectively, at fiscal 2010 year-end. At fiscal 2009 year-end, the fair value of our available-for-sale debt securities 
was $41.2 million, all of which was classified as short-term investments. Gross unrealized gains and losses on available-for-
sale debt securities were $19,000 and ($2,000), respectively, at fiscal 2009 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 and the Japanese Yen. As a result, our earnings 
and cash flows 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 two months or 
less, to manage 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. 

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. 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. 

A hypothetical 10% change in foreign currency rates would not have a material impact on our results of operations 

or financial position. 

The following table provides information about our foreign exchange forward contracts at October 2, 2010. 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. notional fair value represents the 
contracted amount valued at October 2, 2010 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 done 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 2, 2010, 

utilizing the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in 
Internal Control-Integrated Framework. Based on the assessment by management, we determined that our internal control 
over financial reporting was effective as of October 2, 2010. The effectiveness of our internal control over financial reporting 
as of October 2, 2010 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 

Our internal control over financial reporting is 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. The Company’s internal control over financial reporting includes those policies and procedures that: 

(i) 

(ii) 

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions 
and dispositions of the Company’s assets; 

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial 
statements in accordance with generally accepted accounting principles, and that the Company’s receipts 
and expenditures are being made only in accordance with authorizations of the Company’s management 
and directors; and 

(iii) 

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the Company’s assets that could have a material effect on the financial statements. 

52 
Management, including our CEO and CFO, does not expect that the Company’s 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 2, 2010 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.: 

We have audited the internal control over financial reporting of Coherent, Inc. and its subsidiaries (collectively, the 

“Company”) as of October 2, 2010, based on the criteria established in Internal Control—Integrated Framework 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 2, 2010, based on the criteria established in Internal Control—Integrated Framework 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 2, 2010, of the Company and our report 
dated December 14, 2010, expressed an unqualified opinion on those consolidated financial statements.

Pre-Approval of Audit and Non-Audit Services 

The Audit Committee has determined that the provision of non-audit services by Deloitte is compatible with 
maintaining Deloitte’s independence. In accordance with its charter, the Audit Committee approves in advance all audit and 
non-audit services to be provided by Deloitte. In other cases, the Chairman of the Audit Committee has the delegated 
authority from the Committee to pre-approve certain additional services, and such pre-approvals are communicated to the full 
Committee at its next meeting. During fiscal year 2010, 100% of the services were pre-approved by the Audit Committee in 
accordance with this policy.

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 2010 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 users 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 control 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 2, 2010 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 Financing 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.: 

We have audited the accompanying consolidated balance sheets of Coherent, Inc. and its subsidiaries (collectively, 

the “Company”) as of October 2, 2010 and October 3, 2009, and the related consolidated statements of operations, 
stockholders’ equity, and cash flows for each of the three years in the period ended October 2, 2010. 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 2, 2010 and October 3, 2009, and the results of its operations and its cash flows for each of the 
three years in the period ended October 2, 2010, 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 2, 2010, based on the criteria established in 
Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission and our report dated December 14, 2010 expressed an unqualified opinion on the Company’s internal control 
over financial reporting.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1. DESCRIPTION OF BUSINESS 

Founded in 1966, Coherent, Inc. provides photonics-based solutions in a broad range of commercial and scientific 

research applications. We design, manufacture, service and market lasers, laser tools and related accessories for a diverse 
group of customers. Headquartered in Santa Clara, California, we have worldwide operations including research and 
development, manufacturing, sales, service and support capabilities. 

2. SIGNIFICANT ACCOUNTING POLICIES 

Fiscal Year 

Our fiscal year ends on the Saturday closest to September 30. Fiscal years 2010, 2009 and 2008 ended on October 2, 

October 3, and September 27, respectively, and are referred to in these financial statements as fiscal 2010, fiscal 2009, and 
fiscal 2008 for convenience. Fiscal 2009 included 53 weeks; fiscal 2010 and 2008 included 52 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. 
Investments in business entities in which we do not have control, but have the ability to exercise significant influence over 
operating and financial policies (generally 20-50% ownership) are accounted for by the equity method. 

Fair Value of Financial Instruments 

The carrying amounts of certain of our financial instruments including cash and cash equivalents, 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 related to our deferred compensation plans, which are carried at fair value. The recorded carrying amount of 
our long-term obligations approximates fair value at fiscal 2010 and 2009 year-ends. 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. 

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 2010 year-end, the majority of our short-term 
investments are in bank certificates of deposit, federal agency obligations and money market funds. Cash equivalents and 
short-term investments are maintained with several financial institutions and may exceed the amount of insurance provided 
on such balances. 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. We maintain reserves for potential credit losses. Our products are 
broadly distributed and there were no customers who accounted for more than 10% of accounts receivable at fiscal 2010 or 
fiscal 2009 year-end.

Accounts Receivable Allowances 

Accounts receivable allowances reflect our best estimate of probable losses inherent in our accounts receivable 

balances. We regularly review allowances by considering factors such as historical experience, credit quality, the age of the 
accounts receivable balances and current economic conditions that may affect a customer’s ability to pay.

The fair value 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 Finland site. We estimated that as of fiscal 2010 year-end, 
gross expected future cash flows of $2.1 million would be required to fulfill these obligations.

At October 2, 2010, $328,000 of the asset retirement liability is reported in other current liabilities and $1,409,000 is 

reported in other long-term liabilities on our consolidated balance sheets. At October 3, 2009, $337,000 of the asset 
retirement liability is reported in other current liabilities and $1,342,000 is reported 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 2010, 2009 and 2008, there were no significant asset 
impairments recorded. 

Goodwill 

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

down when impaired (see Note 8). Goodwill is tested for impairment by comparing the respective fair value with the 
respective carrying value of the reporting unit. Fair value is determined using the Income Approach (discounted cash flow 
approach) valuation methodology. Absent any impairment indicators, we perform our annual impairment tests at the 
beginning of the fourth quarter of each fiscal year using 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. 

Intangible Assets 

Intangible assets, including acquired existing technology, patents, customer lists, order backlog, trade name, non-

compete agreements, production know-how and in-process research and development are amortized on a straight-line basis 
over estimated useful lives of one year to fifteen years. 

Warranty Reserves 

We provide warranties on certain 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.

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 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 vast majority of our sales are made to original equipment manufacturers (“OEMs”), distributors, resellers 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. 

Our sales to distributors, resellers and end-user customers typically do not have customer acceptance provisions and 

only certain of our sales to OEM customers 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 by the customer’s acceptance of 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 credit to research and development cost. Amounts offset against research and 
development costs were not material in any of the periods presented. 

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. 

68 
 
 
Derivatives 

U.S. GAAP requires that all derivatives, whether designated in hedging relationships or not, be recorded on the 

balance sheet at fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative 
and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow 
hedge, the effective portions of the changes in the fair value of the derivative are recorded in OCI and are recognized in the 
income statement when the hedged item affects earnings. Ineffective portions of changes in the fair value of cash flow hedges 
are recognized in other income (expense). 

Our objective of holding derivatives is to minimize the risks of foreign currency fluctuation by using the most 

effective methods to eliminate or reduce the impact of these exposures. Principal currencies hedged include the Euro, 
Japanese Yen, British Pound, Korean Won, Chinese Renminbi and Canadian dollar. 

For foreign currency forward contracts, hedge effectiveness is measured by comparing the cumulative change in the 

hedge contract with the cumulative change in the hedged item, both of which are based on forward rates. For foreign 
currency option contracts, hedge effectiveness is asserted when the critical elements representing the total changes in the 
option’s cash flows continue to match the related elements of the hedged forecasted transaction. Should discrepancies arise, 
effectiveness is measured by comparing the change in option value and the change in value of a hypothetical derivative 
mirroring the critical elements of the forecasted transaction. 

Forwards not designated as hedging instruments are also used to hedge the impact of the variability in exchange 

rates on accounts receivable and collections denominated in certain foreign currencies. Our forward contracts have maturities 
of two months or less and changes in fair value of these derivatives are recognized in other income (expense). 

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 and is presented in our Consolidated Statements of 
Stockholders’ Equity and in Note 15, “Accumulated Other Comprehensive Income (Loss).” 

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. 

The following table presents information necessary to calculate basic and diluted earnings (loss) per share (in 

thousands, except per share data):

share calculation for fiscal 2010, 2009 and 2008, respectively, as their effect was anti-dilutive. 

69 
 
 
 
Stock-Based Compensation 

We account for stock-based compensation using the fair value of the awards granted. We estimate the fair value of 

stock options granted using the Black-Scholes Merton 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 amortize the fair value of 
stock options on a straight-line basis over the requisite service periods of the awards, which are generally the vesting periods. 
We value restricted stock units using the intrinsic value method. We amortize the value of restricted stock units on a straight-
line basis over the restriction period. See Note 14 “Employee Stock 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 revenue in cost of sales for all periods presented. 

Advertising Costs 

Advertising costs are expensed as incurred and were $2.6 million, $2.2 million and $2.3 million in fiscal 2010, fiscal 

2009 and fiscal 2008, respectively. 

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 allowance for the deferred tax 
asset would be charged to income in the period such determination was made. 

Federal income taxes have not been provided for 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 of foreign 
subsidiaries for which we have not yet recorded federal income taxes was approximately $129.4 million at fiscal 2010 year-
end. In addition to federal income taxes (which are not practicably determinable), withholding taxes of approximately 
$5.9 million at fiscal 2010 year-end would be payable upon repatriation of such earnings which would result in additional 
foreign tax credits. 

Adoption of New Accounting Pronouncements 

In December 2007 the Financial Accounting Standards Board (“FASB”) revised the authoritative guidance for 

business combinations. The revised guidance retains the fundamental requirements of the original pronouncement requiring 
that the purchase method be used for all business combinations, however these rules, (including additional guidance issuance 
after December 2007), change certain elements of accounting for business combinations such as: 

•  The acquisition date is the date that the acquirer achieves control. 

•  Acquisition related costs are recognized separately from the acquisition and recorded as an expense. 

•  Assets acquired and liabilities assumed in a business combination that arise from contingencies are recognized 

at fair value if fair value can be reasonably estimated; if fair value cannot be reasonably estimated during the 
measurement period, the contingent asset or liability is recognized in accordance with the guidance on 
contingencies. 

70 
We adopted this guidance for acquisitions completed after October 4, 2009, the beginning of our fiscal year 2010. 

The impact of adoption will be largely dependent on the size and nature of the business combinations completed. 

In February 2008, the FASB issued guidance which delayed the effective date regarding fair value measurements 

and disclosures of nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in 
the financial statements on a recurring basis. We adopted this update for fiscal year 2010. The adoption of this standard did 
not have a material impact on our consolidated financial position, results of operations and cash flows. 

In 2008, the FASB issued new requirements regarding the determination of the useful lives of intangible assets and 
accounting for acquired defensive assets. This guidance amends the factors that should be considered in developing renewal 
or extension assumptions used to determine the useful life of a recognized intangible; an entity needs to consider its own 
historical experience adjusted for entity specific factors. In the absence of that experience, an entity shall consider the 
assumptions that market participants would use about renewal or extension options. Defensive assets should be assigned 
useful lives based on the period during which the asset would diminish in value. We adopted this guidance for our fiscal year 
2010 and it is being applied prospectively to intangible assets as we make acquisitions. 

In January 2010, the FASB issued an accounting standard update amending the disclosure requirements for financial 
instruments under fair value. New disclosures required include the amount of significant transfers in and out of levels 1 and 2 
fair value measurements and the reasons for the transfers. In addition, the reconciliation for level 3 activity will be required 
on a gross rather than net basis. The update provides additional guidance related to the level of disaggregation in determining 
classes of assets and liabilities and disclosures about inputs and valuation techniques. We adopted this guidance for our fiscal 
quarter beginning January 3, 2010 and it did not have an impact on our consolidated financial position, results of operations 
and cash flows. 

Recently Issued Accounting Pronouncements 

In June 2009, the FASB issued amendments to the accounting rules for variable interest entities (VIEs) and for 

transfers of financial assets. The new guidance eliminates the quantitative approach previously required for determining the 
primary beneficiary of a variable interest entity and requires ongoing qualitative reassessments of whether an enterprise is the 
primary beneficiary. The determination of whether a company is required to consolidate an entity is based on, among other 
things, an entity’s purpose and design and a company’s ability to direct the activities of the entity that most significantly 
impact the entity’s economic performance. In addition, qualifying special purpose entities (“QSPE”) are no longer exempt 
from consolidation under the amended guidance. The amendments also limit the circumstances in which a financial asset, or 
a portion of a financial asset, should be derecognized when the transferor has not transferred the entire original financial asset 
to an entity that is not consolidated with the transferor in the financial statements being presented, and/or when the transferor 
has continuing involvement with the transferred financial asset. These pronouncements are effective for our first quarter of 
fiscal year 2011. We do not expect them to have a material impact on our consolidated financial position, results of 
operations and cash flows. 

In September 2009, the FASB issued a standard which modifies the revenue recognition guidance for arrangements 
that involve the delivery of multiple elements, such as product, software, services or support, to a customer at different times 
as part of a single revenue generating transaction. This standard provides principles and application guidance to determine 
whether multiple deliverables exist, how the individual deliverables should be separated and how to allocate the revenue in 
the arrangement among those separate deliverables. The standard also expands the disclosure requirements for multiple 
deliverable revenue arrangements. We will adopt this standard on a prospective basis for our first quarter of fiscal year 2011 
and do not expect it to have a material impact on our consolidated financial position, results of operations and cash flows. 

In July 2010, the FASB issued an accounting standard update defining a milestone and determining what criteria 

must be met to apply the milestone method of revenue recognition for research or development transactions. The update 
provides guidance on the criteria which must be met to determine if the milestone method of revenue recognition is 
appropriate, whether a milestone is substantive and the disclosures that must be made if the method is elected. This standard 
should be applied on a prospective basis for milestones reached in fiscal years, and interim periods within those years, 
beginning on or after June 15, 2010. We will adopt this standard on a prospective basis for our first quarter of fiscal year 
2011 and do not expect it to have a material impact on our consolidated financial position, results of operations and cash 
flows.

3. RESTRUCTURING ACTIVITIES 

On April 16, 2008, we announced that we entered into an agreement to sell certain assets of our Auburn Optics 

(“Auburn”) manufacturing operation to Research Electro-Optics, Inc. (“REO”), a privately held optics manufacturing and 
technology company. We also entered into a strategic supply agreement with REO. REO is providing optical manufacturing 
capabilities for us, including fabrication and coating of optical components. The transition of the optics manufacturing assets 
from Auburn to REO was completed in fiscal 2009. The transition resulted in charges primarily for employee terminations, 
supplier qualification, moving costs for related equipment, and other exit related costs associated with a plan approved by 
management. 

During fiscal 2008, we consolidated our German DPSS manufacturing into our Lübeck, Germany site. The transfer 

was completed in our fourth quarter of fiscal 2008. On October 13, 2008, we announced the consolidation of the remainder of 
our Munich facility into our Göttingen site. The transfer was completed in our third quarter of fiscal 2009. The consolidation 
and transfers resulted in charges primarily for employee terminations, other exit related costs associated with a plan approved 
by management and a grant repayment liability. 

During the second quarter of fiscal 2009, we announced our plans to close our facilities in Tampere, Finland and 
St. Louis, Missouri. The closure of our St. Louis site was completed in the fourth quarter of fiscal 2009. The closure of our 
Finland site was scheduled for completion by the end of fiscal 2010, but we delayed the closure due to increased demand for 
products manufactured in Finland. We currently anticipate exiting the facility in the third quarter of fiscal 2011. These 
closure plans have resulted in charges primarily for employee termination and other exit related costs associated with a plan 
approved by management. 

During the first quarter of fiscal 2010, we acquired the assets and certain liabilities of StockerYale, Inc’s laser 

module product line in Montreal, Canada and began to transition those activities to other Coherent facilities in Salem, 
Massachusetts, Wilsonville, Oregon and Sunnyvale, California. The transfer is scheduled to be completed by the end of 
March 2011. These closure plans have resulted in charges primarily for employee termination and other exit related costs 
associated with a plan approved by management. 

Restructuring charges in fiscal 2010 and 2009 are recorded in cost of sales, research and development and selling, 

general and administrative expenses in our consolidated statements of operations. 

The following table presents our current liability as accrued on our balance sheets for restructuring charges. The 

table sets forth an analysis of the components of the restructuring charges and payments and other deductions made against 
the accrual for fiscal 2010 and 2009 (in thousands):

The current year severance related costs are primarily comprised of severance pay, outplacement services, medical 

and other related benefits for employees being terminated due to the transition of activities out of Tampere, Finland and 
Montreal, Canada. The remaining severance related restructuring accrual balance of approximately $0.9 million at October 2, 
2010 is expected to result in cash expenditures through the third quarter of fiscal 2011. The current year facilities related 
charges are primarily related to a loss on the sale of our Finland facility. The other restructuring costs are primarily for a grant 
repayment liability and other exit related costs associated with a plan approved by management.

4. BUSINESS COMBINATIONS 

Beam Dynamics, Inc. 

On April 29, 2010, we acquired Beam Dynamics, Inc. for $5.9 million in cash as allocated below and $0.3 million in 

deferred compensation related to an employment contract, which will be recognized in expense as earned. Beam Dynamics 
manufactures flexible laser cutting tools for the materials processing market. Beam Dynamics has been included in our 
Commercial Lasers and Components segment.

The goodwill recognized from this acquisition resulted primarily from access to anticipated growth in the laser tool 

market and was included in our Commercial Lasers and Components (“CLC”) segment. None of the goodwill from this 
purchase is deductible for tax purposes. 

The identifiable intangible assets are being amortized over their respective useful lives of one to six years. 

In-process research and development (“IPR&D”) consists of three development projects that have not yet reached 
technological feasibility. Acquired IPR&D assets are initially recognized at fair value and are classified as indefinite-lived 
assets until the successful completion or abandonment of the associated research and development efforts. The value assigned 
to IPR&D was determined by considering the value of the products under development to the overall development plan, 
estimating the resulting net cash flows from the projects when completed and discounting the net cash flows to their present 
value. During the development period, these assets will not be amortized as charges to earnings; instead these assets will be 
subject to periodic impairment testing. Upon successful completion of the development process for the acquired IPR&D 
projects, the assets would then be considered finite-lived intangible assets and amortization of the assets will commence. 

We expensed $0.2 million of acquisition-related costs as selling, general and administrative expenses in our 

consolidated statements of operations for our fiscal year 2010. 

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. 

As of October 2, 2010, we had $0.6 million remaining in an escrow account that will be applied towards remaining 

closing costs for the acquisition and payments to the shareholders. The amount is included in current restricted cash on our 
consolidated balance sheet. 

StockerYale, Inc. 

On October 13, 2009, we acquired all the assets and certain liabilities of StockerYale, Inc. (“StockerYale”)’s laser 

module product line in Montreal and its specialty fiber product line in Salem, New Hampshire for $15.0 million in cash. 
StockerYale designs, develops and manufactures low power laser modules, light emitting diode (LED) systems and specialty 
optical fiber products. These assets and liabilities have been included in our Commercial Lasers and Components segment.

The goodwill recognized from this acquisition resulted primarily from anticipated increases in market share and 
synergies of combining these entities and was included in our CLC segment. None of the goodwill from this purchase is 
deductible for tax purposes. 

The identifiable intangible assets are being amortized over their respective useful lives of one to seven years. 

We expensed $0.2 million of acquisition-related costs incurred as selling, general and administrative expenses in our 

consolidated statements of operations for our fiscal year 2010. 

Results of operations for the acquired product lines 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. 

5. FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES 

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. Level 1 valuations are obtained from real-time quotes for transactions in active exchange markets involving 
identical assets. Level 2 valuations are obtained from quoted market prices in active markets involving similar assets. Level 3 
valuations would be based on unobservable inputs to a valuation model and include our own data about assumptions market 
participants would use in pricing the asset or liability based on the best information available under the circumstances; as of 
October 2, 2010 and October 3, 2009, we did not have any assets or liabilities valued based on Level 3 valuations.

6. 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 other comprehensive income (“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).

During fiscal 2010, we received proceeds totaling $28.4 million from the sale of available-for-sale securities and 

realized gross gains of less than $0.1 million. During fiscal 2009, we received proceeds totaling $45.7 million from the sale 
of available-for-sale securities and realized gross losses of less than $0.1 million. 

At October 2, 2010, $0.6 million of cash was restricted for remaining closing costs for the Beam Dynamics 

acquisition and payments to former shareholders. 

At October 2, 2010, gross unrealized losses on our investments with unrealized losses that are not deemed to be 

other-than-temporarily impaired were $2,000 on U.S. Treasury and agency obligations and corporate notes and obligations of 
$15,811,000. 

7. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES 

All derivatives, whether designated in hedging relationships or not, are recorded on the balance sheet at fair value. 

We enter into foreign exchange forwards to minimize the risks of foreign currency fluctuation of specific assets and liabilities 
on the balance sheet; these are not designated as hedging instruments. 

76 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We maintain operations in various countries outside of the United States and 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 and the Japanese Yen. As a result, our earnings and cash flows 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 two months or less, to manage 
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 speculative or trading purposes. 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. 

For derivative instruments that are not designated as hedging instruments, gains and losses are recognized in other 

income (expense).

8. GOODWILL AND INTANGIBLE ASSETS 

During the first quarter of fiscal 2009, our stock price declined substantially which, combined with expectations of 

declines in forecasted operating results due to the slowdown in the global economy, led the Company to conclude that a 
triggering event for review for potential goodwill impairment had occurred. Accordingly, as of December 27, 2008, we 
performed an interim goodwill impairment evaluation. Goodwill is tested for impairment first by comparing each reporting 
unit’s fair value to its respective carrying value. If such comparison indicates a potential impairment, then the impairment is 
determined as the difference between the recorded value of goodwill and its fair value. The performance of this test is a two-
step process. 

77 
 
 
 
 
 
 
 
 
 
 
 
Step 1 of the impairment test involves comparing the fair values of the applicable reporting units with their 

aggregate carrying values, including goodwill. If the carrying amount of a reporting unit exceeds the reporting unit’s fair 
value, we perform Step 2 of the goodwill impairment test to determine the amount of impairment loss. Step 2 of the goodwill 
impairment test involves comparing the fair value of the affected reporting unit’s goodwill against the carrying value of that 
goodwill. 

The reporting units we evaluated for goodwill impairment were determined to be the same as our operating 
segments, Commercial Lasers and Components (“CLC”) and Specialty Lasers and Systems (“SLS”). We determined the fair 
value of our reporting units for the Step 1 test using a weighting of the Income (discounted cash flow), Market and 
Transaction approach valuation methodologies. Management completed and reviewed the results of the Step 1 analysis and 
concluded that a Step 2 analysis was required only for the CLC reporting unit. Our preliminary analysis indicated that the 
entire balance of the goodwill in the CLC reporting unit at that date was impaired and we recorded a non-cash goodwill 
impairment charge of $19.3 million in the first quarter of fiscal 2009. During the second quarter of fiscal 2009, we completed 
the Step 2 analysis for the CLC reporting unit as of December 27, 2008 and determined that no further adjustments for CLC 
were required. The estimated fair value of our SLS reporting unit exceeded its carrying value so no further impairment 
analysis was required for this reporting unit. 

During the second quarter of fiscal 2009, our expectations of declines in forecasted operating results due to the 
slowdown in the global economy and the further declines in our stock price led us to conclude that a triggering event for 
review for potential goodwill impairment had occurred. Accordingly, as of April 4, 2009, we performed an interim goodwill 
impairment evaluation. This interim impairment evaluation utilized the same valuation techniques used in our impairment 
valuation in the first quarter of fiscal 2009. Based on the results of our Step 1 analysis, we determined that no additional 
goodwill impairment was indicated. During the remainder of fiscal 2009 and the first three quarters of fiscal 2010, we noted 
no indications of impairment or triggering events to cause us to review goodwill for potential impairment. 

We performed our annual impairment testing as of the beginning of the fourth quarter using the opening balance 

sheet as of the first day of the fourth quarter of fiscal 2010. Between the completion of that testing and the end of the fourth 
quarter of fiscal 2010, we noted no indications of impairment or triggering events to cause us to review goodwill for potential 
impairment; based on our evaluation, the fair values of each of the two operating segments significantly exceeded their 
carrying value as of that date.

2008, respectively. 

As of October 2, 2010, we had total purchase commitments for inventory of approximately $37.6 million and 

purchase obligations for fixed assets and services of $3.6 million compared to $9.9 million of purchase commitments for 
inventory and $5.2 million of purchase obligations for fixed assets and services at October 3, 2009.

Contingencies 

We are subject to legal claims and litigation arising in the ordinary course of business, such as employment or 

intellectual property claims, including, but not limited to, the matters described below. The outcome of any such matters is 
currently not determinable. Although we do not expect that such legal claims and litigation will ultimately have a material 
adverse effect on our consolidated financial position or results of operations, an adverse result in one or more matters could 
negatively affect our results in the period in which they occur. 

Between February 15, 2007 and March 2, 2007, three purported shareholder derivative lawsuits were filed in the 

United States District Court for the Northern District of California against certain of the Company’s current and former 
officers and directors. The Company is named as a nominal defendant. The complaints generally allege that the defendants 
breached their fiduciary duties and violated the securities laws in connection with the granting of stock options, the 
accounting treatment for such grants, the issuance of allegedly misleading public statements and stock sales by certain of the 
individual defendants. On May 30, 2007, these lawsuits were consolidated under the caption In re Coherent, Inc. Shareholder 
Derivative Litigation, Lead Case No. C-07-0955-JF (N.D. Cal.). On June 25, 2007, the plaintiffs filed an amended 
consolidated complaint. The Company’s Board of Directors appointed a Special Litigation Committee (“SLC”) comprised of 
independent director Sandeep Vij to investigate and evaluate the claims asserted in the derivative litigation and to determine 
what action(s) should be taken with respect to the derivative litigation. On September 8, 2009, Coherent, Inc., by and through 
the SLC, plaintiffs, and certain of Coherent’s former and current officers and directors filed with the court a Stipulation of 
Settlement reflecting the terms of a settlement that would resolve all claims alleged in the consolidated complaint. On 
September 14, 2009, the United States District Court for the Northern District of California issued an order granting 
preliminary approval of the settlement of the three purported shareholder derivative lawsuits. On November 20, 2009, the 
court held a hearing for final approval of the settlement, and on November 24, 2009, the court entered an Order and Final 
Judgment, which approved the settlement and dismissed the action with prejudice. Following receipt of insurance proceeds 
and the payment of the plaintiff attorneys’ fees and expenses, we received a net cash benefit of $2.2 million from the 
settlement on December 11, 2009, which was recorded in selling general and administrative expenses in the Consolidated 
Statement of Operations for the first quarter of fiscal 2010. 

13. STOCKHOLDERS’ EQUITY 

On April 29, 2010, we announced that the Board of Directors had authorized the repurchase of up to $50 million of 

our common stock. During fiscal 2010, we repurchased and retired 1,195,829 shares of outstanding common stock at an 
average price of $36.21 per share for a total of $43.3 million, excluding expenses. Such repurchases were accounted for as a 
reduction in additional paid in capital. At October 2, 2010, $6.7 million remains authorized for repurchase under our current 
stock repurchase program. The timing and size of any purchases will be subject to market conditions. The program is 
authorized for 12 months. 

On February 12, 2008, we announced that the Board of Directors had authorized the repurchase of up to 
$225 million of our common stock through a modified “Dutch Auction” tender offer and an additional $25 million of our 
common stock, following the completion or termination of the tender offer, under our stock repurchase program, terminating 
no later than February 11, 2009. On March 17, 2008, we completed our tender offer, repurchased and retired 7,972,313 
shares of outstanding common stock at a price of $28.50 per share for a total of $228.2 million, including expenses. Such 
repurchases were accounted for as a reduction in additional paid in capital. There were no other repurchases during fiscal 
2009 or fiscal 2008 and the program has expired.

14. EMPLOYEE STOCK OPTION AND BENEFIT PLANS 

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 a limited 
number of 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 as follows (in thousands): 

Cash surrender value of life insurance contracts ......................................
Fair value of mutual funds........................................................................
Total assets ...............................................................................................

Life insurance premiums loads, policy fees and cost of insurance that are paid from the asset investments and gains 
and losses from the asset investments for these plans are recorded as components of other income or expense; such amounts 
were a net gain of $0.7 million in fiscal year 2010, a net loss of $4.3 million in fiscal year 2009 and a net loss of $1.1 million 
in fiscal year 2008. Changes in the obligation to plan participants are recorded as a component of operating expenses and cost 
of sales; such amounts were an expense of $1.6 million in fiscal year 2010, a benefit of $3.6 million in fiscal year 2009 and a 
benefit of $1.4 million in fiscal year 2008. Liabilities associated with participant balances under our deferred compensation 
plans are affected by individual contributions and distributions made, as well as gains and losses on the participant’s 
investment allocation election. 

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. Employees become eligible for participation on their first day of 
employment and for Company matching contributions after completing one year of service. The Company matching 
contribution percentage was decreased from 6% to 4% during fiscal 2009. Our contributions (net of forfeitures) during fiscal 
2010, 2009, and 2008 were $2.6 million, $3.4 million and $4.8 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 2010, 2009 
and 2008, a total of 229,172 shares, 224,226 shares and zero shares, respectively, were purchased by and distributed to 
employees at an average price of $18.50, $19.83 and zero per share, respectively. At fiscal 2010 year-end, we had 371,138 
shares of our common stock reserved for future issuance under the plan. 

In the second quarter of fiscal 2007, the ESPP was suspended and employee contributions made to the ESPP were 

returned while a voluntary review of our historical stock option practices was conducted. The ESPP was reopened on 
March 2, 2008 with an 8 month offering period ending October 31, 2008 and employees began making contributions during 
the second quarter of fiscal 2008. 

82 
 
 
 
 
 
 
 
Stock Option Plans 

We have two Stock Option Plans for which employees and service providers are eligible participants and a non-

employee Directors’ Stock Option Plan for which only non-employee directors are eligible participants. The Directors’ Stock 
Option Plan is designed to work automatically without administration, however to the extent administration is necessary, it 
will be performed by the Board of Directors (or an independent committee thereof). Under these plans, Coherent may grant 
options to purchase up to an aggregate of 5,500,000, 6,300,000 and 689,000 shares of common stock, respectively, of which 
zero, 2,388,066 and 132,000, respectively, remain available for grant at fiscal 2010 year-end. Employee options are generally 
exercisable between two and four years from the grant date at a price equal to the fair market value of the common stock on 
the date of the grant and generally vest 25% to 50% annually. The Company settles stock option exercises with newly issued 
shares of common stock. Grants under employee plans generally expire six years from the original grant date. Director 
options are automatically granted to our non-employee directors. Such directors initially receive a stock option for 24,000 
shares exercisable over a three-year period and an award of restricted stock units of 2,000 shares. Currently, the non-
employee directors receive an annual stock option grant of 6,000 shares exercisable as to 50% of the shares on the day prior 
to each of the next two annual stockholder meetings. Grants under director plans expire ten years from the original grant date. 
In addition, currently each non-employee director receives an annual grant of 2,000 shares of restricted stock units that vest 
on the day prior to the annual stockholder meeting held in the third calendar year following the date of grant. Beginning with 
our next annual meeting of stockholders in 2011, the annual grant for non-employee directors will be 3,500 shares of 
restricted stock units that will vest on February 15 of the calendar year following the grant. 

In the second quarter of fiscal 2007, the Company stopped granting stock options while a voluntary review of our 
historical stock option practices was conducted. The Company resumed granting stock options in the first quarter of fiscal 
2008. 

In April 2008, we initiated a tender offer for non-executive officer employees related to certain discount options 

discovered during our voluntary review of our historical stock option practices. Discount options are options with an exercise 
price that is less than the fair market value of the shares underlying the option at the time of grant. The discounted options 
included in this offer were certain options which vested after December 31, 2004. During the tender offer period, employees 
had the ability to amend the exercise price per share for eligible options to the fair market value of the underlying option as of 
the measurement date of that option, and receive a cash payment for the difference between the discounted share price and 
the amended share price. This amendment was designed to allow holders of discount options to avoid certain adverse tax 
consequences associated with discount options. The offer expired on May 9, 2008. The incremental stock compensation 
expense resulting from the offer was $0.4 million which was recognized immediately as all eligible options were fully vested. 
During fiscal 2010, 2009 and 2008, we also recorded expense of $0.2 million, $0.5 million and $2.5 million, respectively, for 
tax payments to be made to United States and United Kingdom tax authorities on behalf of employees in connection with 
these amended shares. 

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 over the respective requisite service period of the awards. 

Determining Fair Value 

Valuation and amortization method—We estimate the fair value of stock options granted using the 

Black-Scholes-Merton option-pricing formula and a single option award approach. This fair value is then amortized on a 
straight-line basis over the requisite service periods of the awards, which is generally the vesting period. 

Expected Term—The expected term represents the period that our stock-based awards are expected to be 
outstanding and was determined based on historical experience of similar awards, giving consideration to the contractual 
terms of the stock-based awards, vesting schedules and expectations of future employee behavior as influenced by changes to 
the terms of its stock-based awards. 

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. 

83 
Expected Dividend—The expected dividend assumption is based on our current expectations about our anticipated 

dividend policy. 

The fair values of the Company’s stock options granted to employees and shares purchased under the stock purchase 

plan for fiscal 2010, 2009 and 2008 were estimated using the following weighted-average assumptions: 

2008

Total stock-based compensation cost capitalized as part of inventory during fiscal 2010 was $0.9 million. 
$0.9 million was amortized into income during fiscal 2010, which includes amounts capitalized in fiscal 2010 and amounts 
carried over from fiscal 2009. Total stock-based compensation cost capitalized as part of inventory during fiscal 2009 was 
$0.8 million. $0.9 million was amortized into income during fiscal 2009, which includes amounts capitalized in fiscal 2009 
and amounts carried over from fiscal 2008. Management has made an estimate of expected forfeitures and is recognizing 
compensation costs only for those equity awards expected to vest. 

At fiscal 2010 year-end, the total compensation cost related to unvested stock-based awards granted to employees 

under the Company’s stock option and award plans but not yet recognized was approximately $10.1 million, net of estimated 
forfeitures of $1.4 million. This cost will be amortized on a straight-line basis over a weighted-average period of 
approximately 1.3 years and will be adjusted for subsequent changes in estimated forfeitures. 

At fiscal 2010 year-end, the total compensation cost related to options to purchase common shares under the ESPP 

but not yet recognized was approximately $0.1 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 2010 and fiscal 2009, we recorded approximately $0.9 million and $0.0 million, respectively, of excess tax 
benefits as cash flows from financing activities. 

During fiscal 2008, our Board of Directors approved an extension of the exercise period to August 25, 2009 for 

397,500 fully vested stock options previously granted by the Company to employees. As a result, we recorded approximately 
$0.5 million in compensation expense related to the stock option modification during fiscal 2008. There were no extensions 
granted during fiscal 2010 or 2009. 

During fiscal 2010 and fiscal 2008, we recorded cash-based compensation expense of $0.3 million and $0.6 million, 

respectively for cash payments to employees for options that were not able to be exercised due to the internal stock option 
investigation. In addition, we recorded compensation expense of $0.5 million and $1.6 million, respectively, in fiscal 2009 
and fiscal 2008 for tax payments to be made to United States and United Kingdom tax authorities on behalf of employees in 
connection with discounted options previously exercised, for the adverse tax consequences associated with these discount 
options. We also recorded $0.4 million in fiscal 2008 for tax payments to be made to United States tax authorities on behalf 
of employees in connection with shares amended to allow the holders of unexercised discount options to avoid certain 
adverse tax consequences associated with those discount options.

The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying options and 

the quoted price of our common stock for in-the-money options. During fiscal 2010, 2009 and 2008, the aggregate intrinsic 
value of options exercised under the Company’s stock option plans were $6.0 million, $0.1 million and $6.0 million, 
respectively, determined as of the date of option exercise. 

Under our 2001 Stock Plan, employees and non-employee directors are eligible for grants of restricted stock awards 

and/or restricted stock units. Restricted stock awards and restricted stock units are independent of option grants and are 
typically subject to vesting restrictions—either time-based or performance-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 terminates prior to the release of restrictions and cannot be transferred. 

•  The service based restricted stock awards generally vest three years from the date of grant. 

•  The service based restricted stock unit awards are generally subject to annual vesting over three years from the 

date of grant. 

•  The performance-based restricted stock unit award grants are generally subject to a single vest measurement 

three years from the date of grant, depending upon achievement of performance measurements (“Performance 
RSUs”). 

85 
 
The Company granted Performance RSUs during the second quarter of fiscal 2008 which have a single vesting 

measurement date of November 14, 2010. These RSUs vest as to anywhere between 0% and 300% of the targeted amount 
based upon achievement by the Company of (a) an annual revenue threshold amount and (b) adjusted EBITDA percentage 
targets. The Company has determined that the performance target has not been met and these awards were cancelled in fiscal 
2011 with no shares vesting. For the purposes of calculating potentially dilutive shares, performance RSUs have not been 
included. 

The cost of the restricted stock awards and units, determined to be the fair market value of the shares at the date of 

grant, is expensed ratably over the period the restrictions lapse. We had 480,931 units of restricted stock outstanding at fiscal 
2010 year-end and 356,528 shares and units of restricted stock outstanding at fiscal 2009 year-end. 

The following table summarizes our restricted stock award and restricted stock unit activity for fiscal 2010, 2009

In determining our fiscal 2010, 2009 and 2008 tax provisions under ASC Subtopic 740, “Income Taxes”, 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 R&D tax credits, foreign net operating losses and capital 
loss carryforwards at fiscal 2010, 2009 and 2008 year-ends. 

88 
 
 
 
 
 
 
 
 
 
 
 
During fiscal 2010, we increased our valuation allowance on deferred tax assets by $0.6 million to $7.4 million, 

primarily due to capital losses, the reduced ability to utilize California R&D tax credits as a result of the current 
apportionment factor and the reduced ability to utilize foreign net operating losses. 

The net deferred tax asset is classified on the consolidated balance sheets as follows (in thousands): 

Current deferred income tax assets...........................................................
Current deferred income tax liabilities .....................................................
Non-current deferred income tax assets ...................................................
Non-current deferred income tax liabilities..............................................
Net deferred tax assets..............................................................................

We have various tax attribute carryforwards which include the following:

(9,651)
(6,231) 
$65,038  $78,108

• 

• 

• 

Foreign net operating loss carryforwards are $9.8 million, of which $6.3 million have no expiration date and of 
which $3.5 million will expire in fiscal years 2019 to 2030. 

Federal capital loss carryforwards of $1.0 million which will expire in fiscal year 2011 to 2015. State capital 
loss carryforwards of $1.0 million which will expire in fiscal 2011 to 2015. 

Federal R&D credit carryforwards of $12.4 million which will expire in fiscal years 2022 to 2030. California 
R&D credit carryforwards of $15.4 million that have no expiration date. 

• 

Federal foreign tax credit carryforwards of $19.6 million which will expire in fiscal years 2016 to 2019. 

Included in the net deferred tax asset balance is $4.2 million of deferred tax liabilities related to the accumulated 

translation adjustment. The associated tax expenses are recorded as a part of other comprehensive income. 

The Internal Revenue Service (“IRS”) has reviewed and accepted the examination report for the audits of our 2003 

and 2004 U.S. federal income tax returns and this matter is now closed. We had previously agreed to various adjustments 
proposed by the IRS in its Notices of Proposed Adjustments (“NOPAs”) to these returns and there were no additional 
adjustments prior to the IRS concluding the audits and accepting the examination report. The IRS has indicated that it may 
consider an audit of our 2005 and 2006 tax returns. The IRS is also auditing the research and development credits generated 
in the years 1999 through 2001 and carried forward to future tax years. We received a NOPA from the IRS in October 2008 
to decrease the amount of research and development credits generated in years 2000 and 2001. We responded to this NOPA 
and we are disputing the adjustment with the IRS through the appeals process available to us and we have an opening 
conference scheduled in December 2010. We believe that we have provided adequate reserves for any adjustments related to 
these credits that may be determined under the IRS appeals process and therefore we do not anticipate any material impact to 
our financial statements. 

In the third quarter of fiscal 2010, the German tax authorities had concluded the audit of our subsidiary in Göttingen 

for the tax years 1999 through 2001. As a result of the audit settlement, there was a release of income tax reserves under 
ASC 740, “Income Taxes,” (formerly FIN 48) net of the tax audit assessment and the amount was not material. After fiscal 
2010 year-end, the German tax authorities also concluded and issued an assessment for the audit of this subsidiary for the tax 
years 2002 through 2005. Since the written tax audit assessment was received after fiscal 2010 year end, there was no 
adjustment to the ASC 740 net tax reserves in fiscal year 2010. The reserve will be released in fiscal year 2011 and the 
impact of the net tax expense is not material. 

As of October 2, 2010, the total amount of gross unrecognized tax benefits was $50.1 million, of which 
$27.9 million, if recognized, would affect our effective tax rate. As of October 3, 2009, we recorded gross unrecognized tax 
benefits of $58.1 million of which $32.5 million, if recognized, would affect our effective tax rate. Our total gross 
unrecognized tax benefit was classified as long-term taxes payable in the consolidated balance sheets. We include interest 
and penalties related to unrecognized tax benefits within the provision for income taxes. As of October 2, 2010, the total 
amount of gross interest and penalties accrued was $6.9 million, which is classified as long-term taxes payable in the 
consolidated balance sheets. As of October 3, 2009, we had accrued $7.7 million for the gross interest and penalties relating 
to the gross unrecognized tax benefits. 

89 
 
 
Management believes that it has adequately provided for any adjustments that may result from tax examinations. 

However, the outcome of tax audits cannot be predicted with certainty. Should any issues addressed in our tax audits be 
resolved in a manner not consistent with management’s expectations, we could be required to adjust our provision for income 
tax in the period such resolution occurs. Although timing of the resolution and/or closure of audits is highly uncertain, we do 
not believe it is reasonably possible that our unrecognized tax benefits would materially change in the next twelve months. 
We expect to settle the German tax audit previously mentioned within the next twelve months and we anticipate a reduction 
of $1.9 million in our unrecognized tax benefits with no material impact on our effective tax rate. 

A reconciliation of the change in gross unrecognized tax benefits, excluding interest and penalties, is as follows (in 

thousands):

As noted in our table above, we had a reduction of $6.6 million in our gross uncertain tax positions during fiscal 

2010. We recorded a comparable reduction in deferred tax assets, primarily relating to competent authority for these types of 
items and as a result, this reduction did not have an impact on our effective tax rate for fiscal 2010. 

A summary of the fiscal tax years that remain subject to examination, as of October 2, 2010, for our major tax 

jurisdictions is: 

United States—Federal................................................................................... 1999—forward 
United States—Various States ....................................................................... 2001—forward 
Netherlands..................................................................................................... 2005—forward

Japan............................................................................................................... 2004—forward 
United Kingdom ............................................................................................. 2008—forward 

The “Worker, Homeownership and Business Assistance Act of 2009” was enacted on November 6, 2009. Under the 

Act, businesses with net operating losses for tax years 2008 and 2009 may carry back those losses for up to five years. We 
elected to carry back the net operating loss generated in the tax year ended October 3, 2009 to the tax year ended 
September 30, 2006 and we received a refund of $2.7 million. 

In September 2008, the state of California approved its budget which limited our ability to utilize available state net 

operating losses and tax credits. Under this tax law, the utilization of net operating losses was suspended for tax years 2008 
and 2009 and the expiration date of net operating loss carryforwards was extended for a two-year period. Additionally, for tax 
years 2008 and 2009, taxpayers may only utilize available tax credits to reduce 50% of their current tax liability. The new law 
does not affect the amount of net operating loss or tax credit carryforwards that we expect to ultimately use to offset future 
California taxes. However, it did limit the amount of net operating losses and tax credits that we were able to utilize to reduce 
our taxes payable for fiscal year 2010. This amount is not considered material. 

On October 8, 2010, the state of California approved its 2010-2011 budget that includes modifications to tax law 

provisions that were previously set to become effective with tax years beginning on or after January 1, 2011. We are 
assessing the effects of the change in the tax law and will recognize any impacts in fiscal year 2011.

18. SEGMENT AND GEOGRAPHIC INFORMATION 

We are organized into two reportable operating segments: Commercial Lasers and Components (“CLC”) and 
Specialty Lasers and Systems (“SLS”). This segmentation reflects the go-to-market strategies for various products and 
markets. While both segments work to deliver cost-effective solutions, 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 
OEM components and instrumentation and materials processing. SLS develops and manufacturers configurable, 
advanced-performance products largely serving the microelectronics and scientific research 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. 

We have identified CLC and SLS as operating segments for which discrete financial information was available. 

Both units have engineering, marketing, product business management and product line management. 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. Income (loss) 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 (loss) 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, 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. 

The following table provides sales and income (loss) from operations for our operating segments (in thousands):
