IPG Photonics Corporation
2020 Annual Letter
Valentin P. Gapontsev, Ph.D.
Chairman and Chief Executive Officer
ltrphoto_gapontsev.jpg
To Our Stockholders,
Although 2019 proved to be a challenging year, we demonstrated good progress in a number of key growth initiatives. We delivered product cost reductions and differentiated new features and accessories for our core products. Furthermore, we are leveraging one of the largest R&D investments in the laser industry to launch leading edge laser products and systems for new markets to enhance our growth and margin profile and provide greater geographic and end market diversification.
The weaker global macroeconomic backdrop, US-China trade conflict and a more intense competitive landscape in China affected our 2019 financial performance. As a result of these challenges, we experienced a significant decrease in the average selling prices for our products in China, which reduced the dollar value of the laser cutting market. Although we shipped a record number of high power lasers, increasing laser units at 1 kilowatt or greater by 23%, achieving revenue growth was challenging. Despite this challenge, we continue to see customers in the laser cutting market adopt higher power solutions. We increased sales of lasers at 10 kilowatts or greater by more than 25%, even though the second half of the year was weaker for these ultra high power solutions.

ltrquote1.jpg
However, multiple IPG customers are launching new cutting systems using our 12 kilowatt lasers, and we increased sales of 20 kilowatt lasers for cutting applications 8-fold. Many of these are sold with our new ultra high power cutting heads. In addition, we sold our first lasers with high peak power (HPP) and adjustable mode beam (AMB) capability. HPP products deliver peak energy twice the average power of the laser, increasing cutting speed and quality while reducing scrap through closer nesting of parts. Our new AMB lasers permit the broadest range of beam tunability, enabling spatterless welding and enhancing the speed of electric vehicle battery production. When combined with our unique high power pulsed lasers for foil cutting and ultra high power continuous wave (CW) lasers for welding, we see significant opportunities in the electric vehicle battery market in 2020 and beyond.
Augmenting our laser solutions with high power optical heads is a key differentiator versus our laser competitors. In 2019, we delivered record sales of optical heads and other beam delivery accessories, growing sales of these products by 10%. We also shipped our first volume orders of our Laser Depth Dynamics (LDD) process monitoring systems, our patented real-time weld monitoring solution. LDD enables greater use of laser-based welding in automated production environments, and we are pursuing multiple million dollar plus opportunities with this technology and associated laser product sales.
Further, we sold a record number of systems for materials processing in 2019 with revenue increasing 33% excluding Genesis, acquired in December 2018. Standard and custom systems for vehicle and battery production, medical device manufacturing, pipe welding, cleaning and inspection applications drove systems growth. We plan to leverage Genesis’ expertise in robotic systems integration to accelerate laser processing within the transportation, aerospace and industrial end markets.

footer_logo.jpg1


Product innovation remains core to our success and the source of growth over the coming years. In 2019, new product sales were 19% of total revenue and 24% in the fourth quarter alone. Sales of green pulsed lasers used to improve solar cell efficiency increased by more than 60% in 2019. Sales of ultrafast pulsed lasers increased more than 80% year over year off a small base, with more than 50 new projects for these lasers across a wide range of applications processing glass, ceramics, circuit boards, OLED film, batteries and solar cells. We plan to enhance the pulse energy and expand the portfolio of new green, ultraviolet and ultrafast pulsed lasers to increase our available markets.
Sales of medical lasers increased 80% in 2019 as our fiber laser-based system solution received approvals in China and the US. We expect sales into urology and other soft tissue applications to ramp over the coming years off a low base. Our lithotripsy medical laser application uses consumable fibers, which have the potential to develop into a more meaningful recurring revenue stream as the number of installed systems increases. We continue to invest in transformative new products for new application areas as well, including new medical treatments, mid-infrared lasers for spectroscopy, inspection and sensing applications, and ultra high power single mode lasers for aerospace and defense.
We have one of the strongest balance sheets in the industrial automation industry, with more than $1 billion net cash and ample liquidity. This strength allows us to prioritize R&D investments and capital expenditures focusing on long-term objectives - diversifying our business with new products, finding new markets and driving innovations to maintain and increase margins. In 2019, we spent $130 million on research and development and $134 million on capital expenditures for these purposes. In addition, we repurchased $41 million worth of stock and have offset all dilution from employee equity compensation since our anti-dilutive repurchase program began in July 2016.
ltrquote2.jpg
We believe we have significant long-term growth opportunities in laser welding, fine processing of electric vehicle batteries and our portfolio of new products addressing opportunities in micro processing, medical, systems and beam delivery solutions. Within our core business, we believe there is no company that can deliver high power laser solutions at our quality, scale, cost and lead time. We will rely on our core scientific strengths to optimize investment in strategic initiatives critical to the long-term success of the Company, enabling IPG to deliver strong growth in revenue and cash flow.
I want to thank our talented employees for their hard work during a difficult year. I would also like to thank you, our stockholders, for your loyalty and support. As ever, I remain confident in our ability to execute during this more challenging period and deliver on our mission to make our fiber laser technology the tool of choice in mass production.

What Matters Am I Being Asked to Vote On at the Meeting and What Vote is Required to Approve Each Matter?
You are being asked to vote on four proposals.

Proposal 1 requests the election of directors. Each director will be elected by the vote of the plurality of the votes cast when a quorum is present. A "plurality of the votes cast" means that the ten persons receiving the greatest number of votes cast "for" will be elected. "Votes cast" excludes "withhold votes" and any broker non-votes (as defined below). Accordingly, withhold votes and broker non-votes will have no effect on Proposal 1. If you hold your shares in "street name", it is critically important that you submit your voting instructions to your bank or broker if you want your shares to count for Proposal 1.

Only independent directors sit on our three standing Board Committees. Several years ago, the Board established the role of a presiding independent director who is elected annually by the independent directors.11

Proposal

Election of Nine Directors
The Board of Directors recommends a vote FOR each director nominee named in this Proxy Statement.
Annual Election of Entire Board. Stockholders elect each director annually. We do not have a classified board.

Related Person Transactions. Our Nominating and Corporate Governance Committee is responsible for approving or ratifying transactions involving our Company and related persons and determining if the transaction is in, or not inconsistent with, the best interests of our Company and our stockholders.

Stock Ownership Guidelines. Our directors and executive officers are required to own a minimum amount of IPG Photonics shares. We believe that stock ownership requirements align the interests of the directors and officers with our stockholders. Our directors and executive officers fully complied with our guidelines in 2016.

Prohibition on Hedging; Limits on Pledging. Our insider trading policy expressly prohibits directors and employees from engaging in short sales of our common stock or buying or selling puts, calls or derivative securities in connection with IPG Photonics shares. The policy also limits the pledging of IPG Photonics shares.

Annual Self-Assessments. Our Board engages in annual self-evaluations and our committees perform bi-annual self-assessments to determine if they are functioning effectively.

Oversight of Risk Management. As part of its oversight, the entire Board reviews Company strategy and performance and the principal risks involved. The Board allocates risk oversight responsibility among the full Board, the independent directors acting as a group and the three standing committees.
Director Qualifications
Additional information is provided below regarding these and certain other key corporate governance policies, which we believe enable us to manage our business in accordance with high standards of business practices and in the best interest of our stockholders. Several of our policies may be found at investor.ipgphotonics.com/corporate-governance/governance-documents. Note that information on our website does not constitute part of this proxy statement.
Corporate Governance Guidelines
Our Board has adopted Corporate Governance Guidelines that outline, among other matters, the roles and functions of the Board, the responsibilities of various Board committees and the mission of the Board. Each of the Board committees has a written charter that sets forth the purposes, goals and responsibilities of the committees as well as qualification for committee membership, procedures for committee membership, appointment and removal, committee structure and operations and committee reporting to the entire Board.

The Corporate Governance Guidelines provide, among other things, that:
a majority of our Board must be independent,
the Presiding Independent Director presides over executive sessions of independent directors,
the Board appoints all members and chairpersons of the Board committees,
the Audit, Compensation, and Nominating and Corporate Governance Committees consist solely of independent directors,
the independent directors meet periodically in executive sessions without the presence of the non-independent directors or members of our management,
directors may not serve on the boards of more than three other public companies or on more than two other audit committees of public companies,
evaluation of the Board is conducted annually and
the Board and key officers should have a meaningful financial stake in the Company.
The Board reviews changing legal and regulatory requirements, evolving best practices and other developments. The Board modifies the Corporate Governance Guidelines and its other corporate governance policies and practices from time to time, as appropriate.
Executive Sessions. Our independent directors meet privately, without employee directors or management present, at least four times during the year. These private sessions are generally held in conjunction with the regular quarterly Board meetings. Other private meetings of the independent directors are held as often as deemed necessary by them. The Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee meet without employee directors or management present from time to time as they deem necessary.
Director Meetings and Policy Regarding Board Attendance. It has been the practice of our Board and its committees to hold at least four in-person regular meetings each year. The Board and its committees also have telephone meetings throughout the year. In accordance with our Corporate Governance Guidelines, our directors are expected to prepare for, attend and actively participate in meetings of the Board and its committees. Our directors are expected to spend the time needed at each meeting and to meet as frequently as necessary to properly discharge their responsibilities. We encourage members of our Board to attend annual meetings of stockholders, but we do not have a formal policy requiring them to do so.
Stock Ownership Guidelines. The Board adopted stock ownership guidelines to more closely align the interests of our directors and executive officers with those of our long-term stockholders. Under the guidelines, the following persons are expected to maintain a minimum investment in our common stock as follows: for non-employee directors, the lesser of 3,000 shares or three times their annual cash Board retainer (excluding committee retainers); for the Chief Executive Officer, five times his annual salary; and for senior executive officers, the lesser of 5,000 shares or one times their respective annual salaries. Vested stock options and unvested restricted stock units count toward the stock ownership levels. Indirect ownership of shares through a separate legal entity counts toward fulfillment of the ownership guidelines. These ownership levels are to be achieved no later than four years after the election as a director or as an executive officer, except that prior to such time the director or officer is expected to retain a certain portion of stock issued upon exercise of stock options or vesting of restricted stock units until the minimum ownership levels are attained. All directors and executive officers were in compliance with our stock ownership guidelines as of December 31, 2016.
Board Self-Assessments. The Board conducts annual self-evaluations and the committees conduct bi-annual self-assessments to determine whether they are functioning effectively. The Nominating and Corporate Governance Committee oversees(the "NCGC") is responsible for identifying and evaluating nominees for director and for recommending to the Board a slate of nominees for election at the Annual Meeting. The NCGC has recommended, and the Board has approved, the following nominees for terms expiring at the annual meeting to be held in 2021, until a successor is elected and qualified or until his or her earlier death, resignation or removal and, unless otherwise marked, a proxy will be voted for such nominees: Dr. Gapontsev, Dr. Scherbakov, Mr. Samartsev, Mr. Child, Mr. Dougherty, Ms. Lego, Mr. Meurice, Mr. Peeler and Mr. Seifert. All of the director nominees set forth in our proxy card have consented to being named in this Proxy Statement and to serving if elected.

Additionally, our directors participate in continuing education sessions to remain informed on recent trends applicable to their committee duties.

New committee members are also provided training on committee policies, practices and trends. As part of this program, directors are invited to participate in a tour of selected facilities of the Company.

Board Leadership Structure
As of the date of this proxy statement, the positions of Chairman of the Board and Presiding Independent Director are held by two different individuals. Dr. Gapontsev, our Chief Executive Officer, also serves as the Chairman of the Board. Our independent directors determined several years ago that, for effective board governance, it is important to have a presiding independent director. Mr. Gauthier has been selected as the Presiding Independent Director for the term ending June 2017.
Dr. Gapontsev became our Chief Executive Officer and Chairman in 1998. His dual role was created when the Board was first established in 2000. Our directors believe that each of the possible leadership structures for a board has its particular benefits and drawbacks which must be considered in the context of the specific circumstances, culture and challenges facing a company, and that such consideration is the responsibility of a company's board that has a diversity of views and experiences. Our directors come from a variety of organizational backgrounds and have direct experience with a wide range of leadership and management structures. The makeupmember of our Board puts it in a very strong positionsince 2006. At the Annual Meeting our Board size is being reduced from ten to evaluate the pros and cons of the various types of board leadership structures and to ultimately decide which form is in the best interests of our stockholders. The independent directors believe that having Dr. Gapontsev serve in both capacities is in the best interest of the Company and its stockholders because it allows Dr. Gapontsev to more effectively execute the Company's strategic initiatives and business plans. He is the founder of the Company and beneficially owns approximately 14% of the Company's common stock. The duality of Dr. Gapontsev's roles as Chairman and Chief Executive Officer creates clear and unambiguous authority, which is essential to effective management. The Board and management can respond more effectively to a distinct line of authority. Further, given that he is closer to the Company's business than any other Board member and he has the benefit of over nineteen years of operations and executive management experience within the Company, Dr. Gapontsev is best-positioned to set the Board's agenda and provide leadership. Dr. Gapontsev's extensive scientific and business experience also gives him vast industry knowledge, which the Board believes is critical for the chairman of the board of a company that operates in a highly technical industry. The combined Chairman/Chief Executive structure is a leadership model that has served our stockholders well for many years.nine directors.

The Board also recognizes the importance of having in place, and building upon, a counterbalancing structure to ensure that it functions in an appropriately independent manner. As a result, the Board enhanced its governance structure several years ago by creating the position of Presiding Independent Director with leadership authority and responsibilities. The duties and responsibilities of the Presiding Independent Director include: setting the agenda for, and leading, executive sessions of the independent directors; providing consolidated feedback from those meetings to the Chairman and Chief Executive Officer; providing input on the agenda for Board meetings; periodically providing feedback on the quality and quantity of information flow from management; having the authority to call meetings of the independent directors; facilitating discussions outside of scheduled Board meetings among the independent directors on key issues as required; serving as a non-exclusive liaison with the Chairman and Chief Executive Officer in consultation with the other independent directors; interviewing Board candidates as appropriate; and leading the determination of the goals and objectives for the Chairman and Chief Executive Officer with the input of the independent directorsIn considering each director nominee and the annual performance evaluation for him with the inputcomposition of the independent directors and providing that evaluation to the Compensation Committee. In the event of a crisis, the Presiding Independent Director would have an increased role in crisis management oversight. The independent directors of our Board elected Mr. Gauthier as the Presiding Independent Director for the term ending June 2017, and this position is voted upon annually by our independent directors.
The Board believes that the position and responsibilities of a presiding independent director and the regular use of executive sessions of the independent directors without the Chief Executive Officer or other executive officers present, along with the Company's strong committee system and substantial majority of independent directors, allow the Board to maintain effective oversight.
Risk Oversight
The Board and management recognize that effectively monitoring and managing risk are essential to the successful execution of the Company's strategy. The Board reviews strategy regularly with management and provides input to management. As part of its oversight of operations, the entire Board reviews and discusses the performance of the Company and the principal risks involved in the operations and management of the Company. The Board allocates risk oversight responsibility among the full Board, the independent directors acting as a group and the three standing committees of the Board. The Nominating and Corporate Governance Committee

11





periodically reviews risk oversight matters and responsibilities, then makes recommendations to the Board to allocate risk oversight responsibilities.
The Board as a whole, reviews risk management practicesthe NCGC evaluates members based on their expertise and diverse perspectives, experiences, qualifications, attributes and skills because the NCGC believes that these attributes enable a number ofdirector nominee to make significant risks in the course of its reviews of corporate strategy, management reports and other presentations. The independent directors as a group participate in senior executive succession and resource planning. The standing committees also contribute to succession and resource planning oversight for management. The Audit Committee oversees certain financial risks and recommends guidelines to monitor and control such exposures. The Compensation Committee reviews the Company's executive compensation programs, their effectiveness at both linking executive pay to performance and aligning the interests of our executives and our stockholders, and oversees an entity-wide compensation risk assessment. The Nominating and Corporate Governance Committee reviews significant related person transactions with directors, executives and managers and may conduct negotiations on behalf of the Company in connection with related person transactions and retain independent advisors to assist it. The Board's risk oversight role is independent from the Company's day-to-day management, as more than two-thirds of the current directors are independent and therefore have no conflicts that might discourage critical review of the Company's risks.

Board Refreshment and Composition
Board Succession Planning
Our Board’s succession planning focuses primarily on the composition of our Board and its committees, anticipated retirements, succession plans for committee members and chairs, our commitment to Board diversity, and recruiting strategies for adding new directors. In its succession planning, the NCGC and our Board consider the results of our Board’s annual self-assessment, as well as other appropriate information, including the types of skills and experience desirable for future Board members and the needs of our Board and its committees at the time in light of the Company’s long-term strategy.
Thoughtful, Deliberate Board Refreshment Process. The Board’s refreshment actions reflect a thoughtful and deliberate process that was informed by our Company’s strategic needs as well as the Board’s annual self-assessment and director nomination processes.
Appropriately Balance Experience and Perspectives While Ensuring an Orderly Transition. Our Board has taken care as part of its Board refreshment process to appropriately balance new perspectives and the experience of existing directors while undergoing an orderly transition of roles and responsibilities on the Board and its committees.
Importance of Board Diversity. In addition, our Board continues to focus on the importance of Board diversity. One of the two new directors who joined our Board since 2016 is female. Gender diverse candidates have been and are included in our board searches.
DIRECTOR TENURE AND RETIREMENT AGE POLICIES
•    No Term Limits; Appropriate Balance of Skills, Knowledge, Experience and Perspectives.
•    Our Board recognizes the importance of periodic Board refreshment and maintaining an appropriate balance of tenure, experience and perspectives on the Board.
•    We believe it is desirable to maintain a mix of longer-tenured, experienced directors with institutional memory and understanding of our business and culture and newer directors with fresh perspectives. However, we do not impose director tenure limits.
•    The Board believes that directors should not have an expectation of being renominated annually and that the NCGC’s assessment is a key component of its director nomination process.
•    In connection with the Board’s annual self-assessment and director nomination processes, the Board considers upcoming retirements, the average tenure and overall mix of individual director tenures of the Board, the overall mix of the skills, knowledge, experience and diversity, each individual director’s performance and contributions to the work of the Board and its committees, the personal circumstances and other time commitments of directors, along with other factors the Board deems appropriate.
•    The Board believes that, as an alternative to term limits, non-management directors should submit their resignation from the Board upon attaining the age of 72 and on each subsequent anniversary. The Board then considers the needs and circumstances confronting the Board and, upon recommendation of the NCGC, determines whether to accept or decline the resignation.
•    Our Board’s age resignation policy is intended to facilitate our Board’s recruitment of new directors with appropriate skills, experience and backgrounds and provide for an orderly transition of leadership on our Board.

Board Roles and Responsibilities
Role in Risk Management
BOARD OVERSIGHT OF RISK
The Board recognizes that effectively monitoring and managing risk are essential to the successful execution of the Company’s strategy. The Board has oversight for risk management at IPG with a focus on the most significant risks facing the Company, including strategic, operational, financial and compliance risks.
Upon recommendation of the NCGC, the Board allocates risk oversight responsibility among the full Board, the independent directors acting as a group and the three standing committees of the Board as described below. Throughout the year, the Board, the independent directors and the committees to which the Board has delegated responsibility dedicate a portion of their meetings to review and discuss specific risk topics in greater detail.
p23_greyarrowupanddown.jpg
AUDIT COMMITTEE
The Audit Committee oversees the policies, processes and risk relating to the financial statements, financial reporting processes, auditing, cybersecurity and compliance risks. The Audit Committee discusses with management the Company’s risk assessment and risk management practices and, when reviewing and approving the annual audit plan for the Company’s internal audit function, prioritizes audit focus areas based on their potential risk.
COMPENSATION COMMITTEE
The Compensation Committee oversees risk associated with management resources, including executive retention and non-CEO succession planning. It reviews the Company’s executive compensation practices, their effectiveness at linking executive pay to performance and aligning the interests of our executives and our stockholders, without encouraging excessive risk taking. The Compensation Committee annually reviews management’s assessment of compensation risk.
THE NOMINATING AND CORPORATE GOVERNANCE COMMITTEE
The NCGC oversees risk related to the Company’s governance structure and processes, and risks arising from related person transactions. It reviews processes and risk related to Board succession planning, authority delegated to management and certain compliance risk.
p23_greyarrowupanddown.jpg
FULL BOARD
Our entire Board as a whole reviews risk management practices and a number of significant risks in the course of its reviews of corporate strategy, management reports and others.
p23_greyarrowupanddown.jpg
INDEPENDENT DIRECTORS
As a group, the independent directors oversee risks related to CEO succession planning.
The Board’s risk oversight process builds upon management’s risk assessment and mitigation processes, which include reviews of strategic and operational planning; compliance under the Company’s Code of Business Conduct and other policies; the Company’s integrity programs; health, safety and environmental compliance; financial reporting and controllership; and information technology companiesand cybersecurity programs. The Board's oversight role is independent from the Company’s day-to-day management, as well as her membershipsmore than two-thirds of the current directors are independent and therefore have no conflicts that might discourage critical review of the Company’s risks.

Proposal 1 Election of Nine Directors

Role in Management Succession Planning
The Board is focused on ensuring that the Company has emergency and long-term succession plans in place for key senior executive positions. The entire Board annually reviews with the CEO the Company’s plan for succession for the position of the chief executive officer, including the appropriate individual or individuals who are candidates to succeed to this position. In the event of an unexpected departure of the CEO, an emergency succession plan allows for smooth transfer of responsibilities to an individual who may or may not be permanently tasked with the new role. The Compensation Committee, composed entirely of independent directors, periodically reviews the Company’s plan for succession for other audit,senior executive officers.
If the succession plan is triggered for any of these roles, the full Board would participate in the discussion and consideration of any action with a final decision to be made by the full Board. In the event of a senior executive’s departure, both internal and external candidates may be considered for permanent appointment to a given role.
Role in Ethics
All directors, officers and employees are required to abide by IPG’s Code of Business Conduct to ensure that our business is conducted in a consistently legal and ethical manner. These policies form the foundation of a comprehensive process that includes compliance with corporate policies and procedures and a Company-wide focus on uncompromising integrity in every aspect of our operations. Our Code of Business Conduct covers many topics, including antitrust and competition law, conflicts of interest, financial reporting, protection of confidential information, and compliance with all laws and regulations applicable to the conduct of our business. All of our directors and employees receive bi-annual training on our Code of Business Conduct, which is posted on our website at investor.ipgphotonics.com/governance/governance-documents. If the Board grants any waivers from our Code of Business Conduct to any directors or executive officers, or if we amend our Code of Business Conduct, we will, if required, disclose these matters via updates on our website.
Role in Stockholder Engagement
Accountability to our stockholders is an important component of the Company’s success. We recognize the value of building informed relationships with our investors that promote further transparency and accountability.

All three Board committees composed of Acterna.independent directors
Independent directors meet in executive session at each of the Board's in person meetings and as needed outside of regular meetings
There is no single board leadership structure that is optimal in all circumstances. The Board, with its diverse skills and experience, considers the most appropriate leadership structure for the Company in the context of the specific circumstances and challenges facing IPG. The directors come from a variety of organizational backgrounds with direct experiences a wide range of leadership and management structures. The independent directors, who comprise two-thirds of our Board, appropriately challenge management and demonstrate the independence necessary for effective oversight. As a result, the Board is in the best position to evaluate the relative benefits and challenges of different leadership structures and ultimately decide which one best serves the interests of our stockholders.
The independent directors believe that having Dr. Gapontsev serve in the combined role of Chairman and CEO is in the best interest of the Company and its stockholders because it allows Dr. Gapontsev to more effectively execute the Company’s strategic initiatives and business plans. He is the Company's founder and beneficially owns approximately 14% of the Company’s common stock. The duality of Dr. Gapontsev’s roles creates clear and unambiguous authority, which is essential to effective management. Further, given that he is closer to the Company’s business than any other Board member and has the benefit of thirty years of operations, technology, strategy and executive management experience within the Company and its subsidiaries, the Board believes that Dr. Gapontsev is best-positioned to set the Board’s agenda and provide leadership of the board of a B.S.company operating in a highly technical industry.
The Board also recognizes the importance of having in place, and M.E.building upon, a counterbalancing structure to ensure that it functions in Electrical Engineeringan appropriately independent manner. The governance structure approved by the Board endows the position of Presiding Independent Director with leadership duties and responsibilities including:
setting the agenda for and leading executive sessions of the independent directors;
providing consolidated feedback from those meetings to the UniversityChairman and CEO;
providing input on Board meeting agendas;
providing feedback on the quality and quantity of Virginia.information flow from management;

serving as a liaison with the Chairman and CEO;

interviewing Board candidates; and
leading the independent directors in setting the Chairman's and CEO's compensation, goals and objectives, and his annual performance evaluation.

In the event of a crisis, the Presiding Independent Director has an increased role in crisis management oversight. The independent directors of our Board elected Mr. Peeler as the Presiding Independent Director for the term ending May 2020, and this position is voted upon annually by our independent directors.

The Board believes that the position and responsibilities of the Presiding Independent Director and the regular use of executive sessions of the independent directors without the CEO or other executive officers present, along with the Company’s strong committee system and substantial majority of independent directors, allow the Board to maintain effective oversight.


Key Attributes, Experience and Skills

The Audit Committee assists the Board by providing oversight of financial management, the internal auditor function and the independent auditor and providing oversight with respect to our internal controls including that management is maintaining an adequate system of internal control such that there is reasonable assurance that assets are safeguarded and that financial reports are properly prepared; that there is consistent application of generally accepted accounting principles; and that there is compliance with management's financial reporting policies and procedures. The Audit Committee also pre-approves auditing and permissible non-audit services by our independent auditor, reviews and discusses our annual and quarterly financial statements and related disclosures, and coordinates the oversight of our internal and external controls over financial reporting, disclosure controls and procedures and code of business conduct.

Nomination of Directors

Director Eligibility. Our Corporate Governance Guidelinesoften as deemed necessary by them and director membership guidelines approvedare lead by the NominatingPresiding Independent Director. The Audit Committee, the Compensation Committee and Corporate Governance Committee contain Board membership criteria considered by the Nominating and Corporate Governance Committee in recommending nominees for a position on IPG’s Board. The Nominating and Corporate Governance Committee believes that, at a minimum, a director candidate must possess the qualities of high personal integrity and ethics, sound business judgment and support for our Code of Business Conduct. A director candidate must also have sufficientNCGC meet without employee directors or management present from time to devote to the affairs of IPG and service on the Board and committees, and not be engaged in any activity adverse to the Company's interest. The Nominating and Corporate Governance Committee considers, among other things, the following criteria when reviewing a director candidate or an incumbent director:time as they deem necessary.

20





the extent that the director/potential director has demonstrated excellence, leadership and significant experience in a field of endeavor,
whether the director/potential director assists in achieving a collective membership on the Board with a broad spectrum of experience and expertise,
whether the director/potential director meets the independence requirements of the listing standards of the NASDAQ guidelines and SEC rules (where independence is desired),
whether the director/potential director can read and understand financial statement fundamentals and is committed to representing the long-term interests of the Company’s stockholders, while keeping in perspective the interests of the Company’s customers, employees and the public and
whether the director/potential director, by virtue of relevant technical expertise, experience or specialized skill relevant to IPG’s current or future business, can add specific value as a Board member.
In addition, no potential director (excluding any incumbent director) with an age less than 21 years or greater than 72 years is eligible for election as a Board member. Each director/potential director must comply with the limits on other board memberships in our Corporate Governance Guidelines.

The Nominating and Corporate Governance Committee does not assign specific weights to particular criteria and no particular criterion is necessarily applicable to all prospective nominees. In addition to the criteria set forth above, the Nominating and Corporate Governance Committee considers how the skills and attributes of each individual candidate or incumbent director work together to create a Board that is collegial, engaged and effective in performing its duties. The Nominating and Corporate Governance Committee seeks a Board that reflects diversity, in experience, gender and ethnicity, although it does not have formal objective criteria for determining the degree of diversity desired on the Board.

Director Nomination Process. The Nominating and Corporate Governance Committee identifies potential director nominees through contacts of the Board, executives and a variety of other sources. The Committee may retain a search firm or utilize third-party database search tools to identify director nominees. Stockholders may nominate candidates for election as directors as described below.

The Nominating and Corporate Governance Committee will consider several factors prior to nominating a candidate. Generally, the Committee will consider the existing size, future requirements of the Board, composition and skills of the Board, evaluate biographical information and other background material and interview each candidate selected. The Nominating and Corporate Governance Committee will apply any director selection criteria adopted by it based on the circumstances at the time and the criteria set forth in our Corporate Governance Guidelines.

The Nominating and Corporate Governance Committee will consider all director candidates identified through the processes described above and will evaluate each of them, including incumbents, based on the same criteria. Director candidates are evaluated at regular or special meetings of the Nominating and Corporate Governance Committee and may be considered at any point during the year. If based on the Committee’s initial evaluation, a director candidate continues to be of interest to the Nominating and Corporate Governance Committee, the chair of such Committee and other Committee members will interview the candidate and communicate the evaluation to the Committee and executive management. Additional interviews are conducted and all members of the Board may interview the final candidates. Ultimately, the Nominating and Corporate Governance Committee will meet to finalize its list of recommended candidates for the Board’s consideration.

The Nominating and Corporate Governance Committee will also consider candidates for nomination as a director submitted by stockholders. The Nominating and Corporate Governance Committee’s evaluation process and criteria does not vary based upon whether a candidate is recommended by a stockholder. However, the procedural requirements set forth in our by-laws and the procedures described under "Other Matters - 2018 Annual Meeting and Nominations" must be met.

Director Meetings and Policy Regarding Board Attendance
It has been the practice of our Board and alignits committees to hold at least four in-person regular meetings each year.

In 2019, six of the directors in office attended the annual meeting of stockholders.
The table below sets forth the number of meetings held by each committee and the full Board in 2019. All incumbent directors attended 75% or more of the aggregate meetings of the Board and committees on which they served during 2019.

The Board receives presentations from professionals with expertise in corporate law, governance and other related topics. These experts have specialized knowledge of regulatory actions, governance trends and various other corporate governance topics. In 2019, the Board and its committees received presentations on board oversight and stockholder engagement, SEC rulemaking, governance trends, critical accounting matter disclosures and cybersecurity. Additionally, our directors engage in continuing education to remain informed on recent trends applicable to their committee duties.

Further, the performance of the Presiding Independent Director is evaluated annually. The NCGC oversees the Board and committee self-assessments.

Transactions with Related Parties
The Board adopted a related person transaction policy that requires the NCGC to approve or ratify any transaction or series of transactions exceeding $100,000 in which our Company is a participant and any related person has a direct or indirect material interest (other than solely as a result of being a director or trustee or less than 10% owner of another entity) ("Related Party Transactions"). Related persons include our directors, director nominees and officers and their immediate family members and persons sharing their households. It also includes persons controlling more than 5% of our outstanding common stock. Subject to certain exceptions in the policy, related parties are required to notify the NCGC of the Related Party Transaction for an assessment of whether the transaction or proposed transaction should be permitted. Management also has established procedures for monitoring transactions that could be subject to approval or ratification under the Related Party Transactions policy.
In deciding whether to approve or ratify the Related Party Transaction, the NCGC considers relevant facts and circumstances. The committee will take into account, among other factors, whether the transaction is on terms no more favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction. Once a Related Party Transaction has been identified, the NCGC will review all of the relevant facts and circumstances and approve or disapprove entry into the transaction. Members of the NCGC having an interest in a transaction excuse themselves for the consideration and approval of the transaction in which they have an interest. Certain transactions are exempt from the policy including compensation plan described below.

The Board’s risk oversight process builds upon management’s risk assessment and mitigation processes, which include reviews of strategic and operational planning; compliance under the Company’s Code of Business Conduct and other policies; the Company’s integrity programs; health, safety and environmental compliance; financial reporting and controllership; and information technology and cybersecurity programs. The Board's oversight role is independent from the Company’s day-to-day management, as more than two-thirds of the current directors are independent and therefore have no conflicts that might discourage critical review of the Company’s risks.

Proposal 1 Election of Nine Directors

Role in Management Succession Planning
The Board is focused on ensuring that the Company has emergency and long-term succession plans in place for key senior executive positions. The entire Board annually reviews with the CEO the Company’s plan for succession for the position of the chief executive officer, including the appropriate individual or individuals who are candidates to succeed to this position. In the event of an unexpected departure of the CEO, an emergency succession plan allows for smooth transfer of responsibilities to an individual who may or may not be permanently tasked with the new role. The Compensation Committee, composed entirely of independent directors, periodically reviews the Company’s plan for succession for other senior executive officers.
If the succession plan is triggered for any of these roles, the full Board would participate in the discussion and consideration of any action with a final decision to be made by the full Board. In the event of a senior executive’s departure, both internal and external candidates may be considered for permanent appointment to a given role.
Role in Ethics
All directors, officers and employees are required to abide by IPG’s Code of Business Conduct to ensure that our business is conducted in a consistently legal and ethical manner. These policies form the foundation of a comprehensive process that includes compliance with corporate policies and procedures and a Company-wide focus on uncompromising integrity in every aspect of our operations. Our Code of Business Conduct covers many topics, including antitrust and competition law, conflicts of interest, financial reporting, protection of confidential information, and compliance with all laws and regulations applicable to the conduct of our business. All of our directors and employees receive bi-annual training on our Code of Business Conduct, which is posted on our website at investor.ipgphotonics.com/governance/governance-documents. If the Board grants any waivers from our Code of Business Conduct to any directors or executive officers, or if we amend our Code of Business Conduct, we will, if required, disclose these matters via updates on our website.
Role in Stockholder Engagement
Accountability to our stockholders is an important component of the Company’s success. We recognize the value of building informed relationships with our investors that promote further transparency and accountability.
While proxy voting is one direct way to influence corporate behavior, proactive engagement with our investors can be effective and impactful. Investor views are continuously communicated to the Board and are instrumental in the development of our governance, compensation and other policies and inform our business strategy. The Board continues to seek investor input on a range of issues and practices in furtherance of enhancing long-term stockholder value.

All three Board committees composed of independent directors
Independent directors meet in executive session at each of the Board's in person meetings and as needed outside of regular meetings
There is no single board leadership structure that is optimal in all circumstances. The Board, with its diverse skills and experience, considers the most appropriate leadership structure for the Company in the context of the specific circumstances and challenges facing IPG. The directors come from a variety of organizational backgrounds with direct experiences a wide range of leadership and management structures. The independent directors, who comprise two-thirds of our Board, appropriately challenge management and demonstrate the independence necessary for effective oversight. As a result, the Board is in the best position to evaluate the relative benefits and challenges of different leadership structures and ultimately decide which one best serves the interests of our stockholders.
The independent directors believe that having Dr. Gapontsev serve in the combined role of Chairman and CEO is in the best interest of the Company and its stockholders because it allows Dr. Gapontsev to more effectively execute the Company’s strategic initiatives and business plans. He is the Company's founder and beneficially owns approximately 14% of the Company’s common stock. The duality of Dr. Gapontsev’s roles creates clear and unambiguous authority, which is essential to effective management. Further, given that he is closer to the Company’s business than any other Board member and has the benefit of thirty years of operations, technology, strategy and executive management experience within the Company and its subsidiaries, the Board believes that Dr. Gapontsev is best-positioned to set the Board’s agenda and provide leadership of the board of a company operating in a highly technical industry.
The Board also recognizes the importance of having in place, and building upon, a counterbalancing structure to ensure that it functions in an appropriately independent manner. The governance structure approved by the Board endows the position of Presiding Independent Director with leadership duties and responsibilities including:
setting the agenda for and leading executive sessions of the independent directors;
providing consolidated feedback from those meetings to the Chairman and CEO;
providing input on Board meeting agendas;
providing feedback on the quality and quantity of information flow from management;
calling and managing meetings of the independent directors;
facilitating discussions outside of scheduled Board meetings among the independent directors on key issues;
serving as a liaison with the Chairman and CEO;
interviewing Board candidates; and
leading the independent directors in setting the Chairman's and CEO's compensation, goals and objectives, and his annual performance evaluation.
In the event of a crisis, the Presiding Independent Director has an increased role in crisis management oversight. The independent directors of our Board elected Mr. Peeler as the Presiding Independent Director for the term ending May 2020, and this position is voted upon annually by our independent directors.
The Board believes that the position and responsibilities of the Presiding Independent Director and the regular use of executive sessions of the independent directors without the CEO or other executive officers present, along with the Company’s strong committee system and substantial majority of independent directors, allow the Board to maintain effective oversight.



26 NOTICE OF 2020 ANNUAL MEETING AND PROXY STATEMENT


Proposal 1 Election of Nine Directors

Director Independence
Seven of our ten current directors are independent as defined by Nasdaq and SEC rules. A predominantly independent Board ensures that the Board is acting objectively and in the best interests of our stockholders. The independent directors also bring expertise and a diversity of perspectives to the Board. The culture of the Board enables directors to openly express their opinions in the boardroom and to raise challenges. Nasdaq listing standards governing independence require that a majority of the members of the Board be independent as defined by Nasdaq. The Board conducted its annual review of director independence in March 2020. During this review, the Board examined all direct and indirect transactions or relationships between the Company or any of its subsidiaries and each current director and any immediate family member of the director and determined that no material relationships with the Company existed during 2019. On the basis of this review, the Board determined that each of the following directors qualifies as an independent director as defined in Nasdaq guidelines and SEC rules: Michael C. Child, Gregory P. Dougherty, Henry E. Gauthier, Catherine P. Lego, Eric Meurice, John R. Peeler and Thomas J. Seifert. Additionally, the Board has determined that each member of the Audit Committee and the Compensation Committee meets the independence standards specific for members of such committees under Nasdaq guidelines and SEC rules.
Our Corporate Governance Guidelines require that a majority of the Board members must consist of independent directors. In general, our Corporate Governance Guidelines also require that an independent director must have no material relationship with the Company, directly or indirectly, that might interfere with the exercise of independent judgment in the performance of director responsibilities. The Board determines independence on the basis of the standards specified by Nasdaq, the additional standards referenced in our Corporate Governance Guidelines, and other facts and circumstances the Board considers relevant. The NCGC conducts an annual review of the independence of the directors (and candidates for membership on the Board), taking into account all relevant facts and circumstances, and reports its findings to the full Board.
Executive Sessions. Our independent directors meet privately, without employee directors or management present, at least four times during the year. These private sessions are generally held in conjunction with the regular quarterly Board meetings. Other private meetings of the independent directors are held as often as deemed necessary by them and are lead by the Presiding Independent Director. The Audit Committee, the Compensation Committee and the NCGC meet without employee directors or management present from time to time as they deem necessary.
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
No member of our Compensation Committee (Ms. Lego and Messrs. Dougherty, Meurice and Peeler) is or has been an officer or employee of our Company or any of our subsidiaries. None of our executive officers served as a member of:
the compensation committee of another entity in which one of the executive officers of such entity served on our Compensation Committee;
the compensation committee of another entity in which one of the executive officers of such entity served as a member of our Board; or
the board of directors of another entity, one of whose executive officers served on our Compensation Committee.

Director Meetings and Policy Regarding Board Attendance
It has been the practice of our Board and its committees to hold at least four in-person regular meetings each year. The Board and its committees also have telephone meetings throughout the year. Our directors are expected to spend the time needed to prepare for and participate in each meeting and to meet as frequently as necessary to properly discharge their responsibilities.

In 2019, six of the directors in office attended the annual meeting of stockholders.

Proposal 1 Election of Nine Directors

Corporate Governance Guidelines
Our Board adopted Corporate Governance Guidelines that outline, among other matters, the roles and functions of the Board, the responsibilities of various Board committees and the mission of the Board. Our Corporate Governance Guidelines can be found at investor.ipgphotonics.com/governance/governance-documents. Information on our website does not constitute part of this Proxy Statement.
The Corporate Governance Guidelines provide, among other things, that:
a majority of our Board must be independent
the Presiding Independent Director presides over executive sessions of independent directors
the Board appoints all members and chairpersons of the Board committees
the Audit Committee, Compensation Committee, and NCGC consist solely of independent directors
the independent directors meet periodically in executive sessions without the employee directors or management
independent directors may not serve on the boards of more than three other public companies or, with the permission of the Board, four; the CEO may not serve on more than one other public company board
Board self-assessments are conducted annually and
the Board and key officers should have a meaningful financial stake in the Company.
The Board monitors changing legal and regulatory requirements, evolving best practices and other developments. The Board modifies the Corporate Governance Guidelines and its other corporate governance policies and practices from time to time, as appropriate.
Director Orientation and Continuing Education
The Board and its committees proactively monitor legislative and regulatory initiatives, as well as other corporate governance trends and their potential impact on the Company. The Board receives presentations from professionals with expertise in corporate law, governance and other related topics. These experts have specialized knowledge of regulatory actions, governance trends and various other corporate governance topics. In 2019, the Board and its committees received presentations on board oversight and stockholder engagement, SEC rulemaking, governance trends, critical accounting matter disclosures and cybersecurity. Additionally, our directors engage in continuing education to remain informed on recent trends applicable to their committee duties.
Likewise, newly elected directors attend a comprehensive director orientation program that covers, among other things, our strategy, business structure, financial performance, and competitive landscape. New committee members are also provided training on committee policies, practices and trends. As part of this program, directors are asked to tour facilities as appropriate. To further familiarize directors with our expanding operations, we conduct Board meetings at our major manufacturing facilities from time to time.
Board Performance Evaluations
The Board conducts annual self-assessments and its committees conduct bi-annual self-assessments to determine whether they are functioning effectively. Further, the performance of the Presiding Independent Director is evaluated annually. The NCGC oversees the Board and committee self-assessments. Each committee also reviews its own performance bi-annually and reports the results to the Board. Each committee reviews and reassesses the adequacy of its charter annually and recommends proposed changes to the Board.
Prohibition on Hedging; Limits on Pledging
Under our insider trading policy, no director or employee, including NEOs, may engage in shorting shares of our common stock; buying or selling puts, calls or derivatives related to our common stock or other Company securities, which includes equity compensation; or engaging in hedging transactions, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars and exchange funds. No director or officer, including NEOs, may pledge shares constituting more than 20% of his or her total stock ownership. Pledges of shares constituting 20% or less of total stock ownership are subject to certain conditions.

Communication with our Board of Directors
Interested parties wishing to write to the Board, a specified director or a committee of the Board should send correspondence to the Office of the Secretary, IPG Photonics Corporation, 50 Old Webster Road, Oxford, Massachusetts 01540. All written communications received in such manner from stockholders of the Company will be forwarded to the members or committee of the Board to whom the communication is directed or, if the communication is not directed to any particular member(s) or committee(s) of the Board, the communication shall be forwarded to all members of the Board.
Procedures for Submitting Complaints
We have procedures to treat complaints regarding accounting, internal accounting controls, auditing matters, fight against bribery, banking, and financial crime, including submission of confidential and anonymous concerns regarding questionable accounting, internal accounting controls or auditing matters raised by our directors, officers and employees. These procedures are posted on our website at investor.ipgphotonics.com/governance/governance-documents.
Transactions with Related Parties
The Board adopted a related person transaction policy that requires the NCGC to approve or ratify any transaction or series of transactions exceeding $100,000 in which our Company is a participant and any related person has a direct or indirect material interest (other than solely as a result of being a director or trustee or less than 10% owner of another entity) ("Related Party Transactions"). Related persons include our directors, director nominees and officers and their immediate family members and persons sharing their households. It also includes persons controlling more than 5% of our outstanding common stock. Subject to certain exceptions in the policy, related parties are required to notify the NCGC of the Related Party Transaction for an assessment of whether the transaction or proposed transaction should be permitted. Management also has established procedures for monitoring transactions that could be subject to approval or ratification under the Related Party Transactions policy.
In deciding whether to approve or ratify the Related Party Transaction, the NCGC considers relevant facts and circumstances. The committee will take into account, among other factors, whether the transaction is on terms no more favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction. Once a Related Party Transaction has been identified, the NCGC will review all of the relevant facts and circumstances and approve or disapprove entry into the transaction. Members of the NCGC having an interest in a transaction excuse themselves for the consideration and approval of the transaction in which they have an interest. Certain transactions are exempt from the policy including compensation paid by the Company for service as a director or an officer.
Pursuant to our Corporate Governance Guidelines, we expect each of our directors to ensure that other existing and future commitments do not conflict with or materially interfere with his or her service as a director. In addition, directors are required to inform the chairman of our NCGC prior to joining the Board of another public company to ensure that any potential conflicts, excessive time demands or other issues are carefully considered.
The NCGC reviewed and approved the following Related Party Transaction for 2019 in compliance with our policy:
Dr. Gapontsev leases the annual right to use 25% of the Company’s corporate aircraft under a July 2017 lease agreement (the “Aircraft Lease”) in connection with the purchase of an aircraft. The Aircraft Lease expires in July 2022. The annual lease rate under the Aircraft Lease is $924,700 and future rent payments are adjusted annually. Dr. Gapontsev paid the Company $923,712 in 2019 for use of the aircraft, and in addition, directly paid an unrelated flight management firm for the operating costs of his private use, including pilot fees, fuel and other costs.

The aggregate amount of equity compensation and vesting conditions remain the same.

COMPENSATION COMMITTEE REPORT

The Compensation Committee of the Board of Directors has reviewed and discussed with management the Compensation Discussion and Analysis included in this proxy statement. Based on this review and discussion, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in the Company's proxy statement for the Company's 2017 annual meeting of stockholders and in the Company's Annual Report on Form 10-K for the year ended December 31, 2016.
The information in this Compensation Committee Report shall not be considered "soliciting material" or "filed" with the SEC, nor shall this information be incorporated by reference into any previous or future filings under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except to the extent that the Company incorporates it by specific reference.

COMPENSATION COMMITTEE
John R. Peeler, ChairThe Compensation Committee oversees risk associated with management resources, including executive retention and non-CEO succession planning. It reviews the Company’s executive compensation practices, their effectiveness at linking executive pay to performance and aligning the interests of our executives and our stockholders, without encouraging excessive risk taking. The Compensation Committee annually reviews management’s assessment of compensation risk.
THE NOMINATING AND CORPORATE GOVERNANCE COMMITTEE
William S. HurleyThe NCGC oversees risk related to the Company’s governance structure and processes, and risks arising from related person transactions. It reviews processes and risk related to Board succession planning, authority delegated to management and certain compliance risk.
p23_greyarrowupanddown.jpg
FULL BOARD
Our entire Board as a whole reviews risk management practices and a number of significant risks in the course of its reviews of corporate strategy, management reports and others.
p23_greyarrowupanddown.jpg
INDEPENDENT DIRECTORS
As a group, the independent directors oversee risks related to CEO succession planning.
The Board’s risk oversight process builds upon management’s risk assessment and mitigation processes, which include reviews of strategic and operational planning; compliance under the Company’s Code of Business Conduct and other policies; the Company’s integrity programs; health, safety and environmental compliance; financial reporting and controllership; and information technology and cybersecurity programs. The Board's oversight role is independent from the Company’s day-to-day management, as more than two-thirds of the current directors are independent and therefore have no conflicts that might discourage critical review of the Company’s risks.


24 NOTICE OF 2020 ANNUAL MEETING AND PROXY STATEMENT


Proposal 1 Election of Nine Directors

Role in Management Succession Planning
The Board is focused on ensuring that the Company has emergency and long-term succession plans in place for key senior executive positions. The entire Board annually reviews with the CEO the Company’s plan for succession for the position of the chief executive officer, including the appropriate individual or individuals who are candidates to succeed to this position. In the event of an unexpected departure of the CEO, an emergency succession plan allows for smooth transfer of responsibilities to an individual who may or may not be permanently tasked with the new role. The Compensation Committee, composed entirely of independent directors, periodically reviews the Company’s plan for succession for other senior executive officers.
If the succession plan is triggered for any of these roles, the full Board would participate in the discussion and consideration of any action with a final decision to be made by the full Board. In the event of a senior executive’s departure, both internal and external candidates may be considered for permanent appointment to a given role.
Role in Ethics
All directors, officers and employees are required to abide by IPG’s Code of Business Conduct to ensure that our business is conducted in a consistently legal and ethical manner. These policies form the foundation of a comprehensive process that includes compliance with corporate policies and procedures and a Company-wide focus on uncompromising integrity in every aspect of our operations. Our Code of Business Conduct covers many topics, including antitrust and competition law, conflicts of interest, financial reporting, protection of confidential information, and compliance with all laws and regulations applicable to the conduct of our business. All of our directors and employees receive bi-annual training on our Code of Business Conduct, which is posted on our website at investor.ipgphotonics.com/governance/governance-documents. If the Board grants any waivers from our Code of Business Conduct to any directors or executive officers, or if we amend our Code of Business Conduct, we will, if required, disclose these matters via updates on our website.
Role in Stockholder Engagement
Accountability to our stockholders is an important component of the Company’s success. We recognize the value of building informed relationships with our investors that promote further transparency and accountability.
While proxy voting is one direct way to influence corporate behavior, proactive engagement with our investors can be effective and impactful. Investor views are continuously communicated to the Board and are instrumental in the development of our governance, compensation and other policies and inform our business strategy. The Board continues to seek investor input on a range of issues and practices in furtherance of enhancing long-term stockholder value.

Proposal 1 Election of Nine Directors

Board Structure
Board Leadership Structure
Chairman of the Board and Chief Executive Officer: Dr. Valentin P. Gapontsev
Presiding Independent Director: John R. Peeler
Presiding Independent Director position is appointed annually by independent directors
All three Board committees composed of independent directors
Independent directors meet in executive session at each of the Board's in person meetings and as needed outside of regular meetings
There is no single board leadership structure that is optimal in all circumstances. The Board, with its diverse skills and experience, considers the most appropriate leadership structure for the Company in the context of the specific circumstances and challenges facing IPG. The directors come from a variety of organizational backgrounds with direct experiences a wide range of leadership and management structures. The independent directors, who comprise two-thirds of our Board, appropriately challenge management and demonstrate the independence necessary for effective oversight. As a result, the Board is in the best position to evaluate the relative benefits and challenges of different leadership structures and ultimately decide which one best serves the interests of our stockholders.
The independent directors believe that having Dr. Gapontsev serve in the combined role of Chairman and CEO is in the best interest of the Company and its stockholders because it allows Dr. Gapontsev to more effectively execute the Company’s strategic initiatives and business plans. He is the Company's founder and beneficially owns approximately 14% of the Company’s common stock. The duality of Dr. Gapontsev’s roles creates clear and unambiguous authority, which is essential to effective management. Further, given that he is closer to the Company’s business than any other Board member and has the benefit of thirty years of operations, technology, strategy and executive management experience within the Company and its subsidiaries, the Board believes that Dr. Gapontsev is best-positioned to set the Board’s agenda and provide leadership of the board of a company operating in a highly technical industry.
The Board also recognizes the importance of having in place, and building upon, a counterbalancing structure to ensure that it functions in an appropriately independent manner. The governance structure approved by the Board endows the position of Presiding Independent Director with leadership duties and responsibilities including:
setting the agenda for and leading executive sessions of the independent directors;
providing consolidated feedback from those meetings to the Chairman and CEO;
providing input on Board meeting agendas;
providing feedback on the quality and quantity of information flow from management;
calling and managing meetings of the independent directors;
facilitating discussions outside of scheduled Board meetings among the independent directors on key issues;
serving as a liaison with the Chairman and CEO;
interviewing Board candidates; and
leading the independent directors in setting the Chairman's and CEO's compensation, goals and objectives, and his annual performance evaluation.
In the event of a crisis, the Presiding Independent Director has an increased role in crisis management oversight. The independent directors of our Board elected Mr. Peeler as the Presiding Independent Director for the term ending May 2020, and this position is voted upon annually by our independent directors.
The Board believes that the position and responsibilities of the Presiding Independent Director and the regular use of executive sessions of the independent directors without the CEO or other executive officers present, along with the Company’s strong committee system and substantial majority of independent directors, allow the Board to maintain effective oversight.

Director Independence
Seven of our ten current directors are independent as defined by Nasdaq and SEC rules. A predominantly independent Board ensures that the Board is acting objectively and in the best interests of our stockholders. The independent directors also bring expertise and a diversity of perspectives to the Board. The culture of the Board enables directors to openly express their opinions in the boardroom and to raise challenges. Nasdaq listing standards governing independence require that a majority of the members of the Board be independent as defined by Nasdaq. The Board conducted its annual review of director independence in March 2020. During this review, the Board examined all direct and indirect transactions or relationships between the Company or any of its subsidiaries and each current director and any immediate family member of the director and determined that no material relationships with the Company existed during 2019. On the basis of this review, the Board determined that each of the following directors qualifies as an independent director as defined in Nasdaq guidelines and SEC rules: Michael C. Child, Gregory P. Dougherty, Henry E. Gauthier, Catherine P. Lego, Eric Meurice, John R. Peeler and Thomas J. Seifert. Additionally, the Board has determined that each member of the Audit Committee and the Compensation Committee meets the independence standards specific for members of such committees under Nasdaq guidelines and SEC rules.
Our Corporate Governance Guidelines require that a majority of the Board members must consist of independent directors. In general, our Corporate Governance Guidelines also require that an independent director must have no material relationship with the Company, directly or indirectly, that might interfere with the exercise of independent judgment in the performance of director responsibilities. The Board determines independence on the basis of the standards specified by Nasdaq, the additional standards referenced in our Corporate Governance Guidelines, and other facts and circumstances the Board considers relevant. The NCGC conducts an annual review of the independence of the directors (and candidates for membership on the Board), taking into account all relevant facts and circumstances, and reports its findings to the full Board.
Executive Sessions. Our independent directors meet privately, without employee directors or management present, at least four times during the year. These private sessions are generally held in conjunction with the regular quarterly Board meetings. Other private meetings of the independent directors are held as often as deemed necessary by them and are lead by the Presiding Independent Director. The Audit Committee, the Compensation Committee and the NCGC meet without employee directors or management present from time to time as they deem necessary.
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
No member of our Compensation Committee (Ms. Lego and Messrs. Dougherty, Meurice and Peeler) is or has been an officer or employee of our Company or any of our subsidiaries. None of our executive officers served as a member of:
the compensation committee of another entity in which one of the executive officers of such entity served on our Compensation Committee;
the compensation committee of another entity in which one of the executive officers of such entity served as a member of our Board; or
the board of directors of another entity, one of whose executive officers served on our Compensation Committee.

Stockholders should understand that the designation of Ms. Lego and Mr. Seifert each as an “audit committee financial expert” is an SEC disclosure requirement and that it does not impose upon them any duties, obligations or liabilities that are greater than those imposed on them as members of the Audit Committee and the Board in the absence of such designation.

p30_timelinegraphica01.jpg
Director Meetings and Policy Regarding Board Attendance
It has been the practice of our Board and its committees to hold at least four in-person regular meetings each year. The Board and its committees also have telephone meetings throughout the year. Our directors are expected to spend the time needed to prepare for and participate in each meeting and to meet as frequently as necessary to properly discharge their responsibilities. We encourage members of our Board to attend annual meetings of stockholders, but we do not have a formal policy requiring them to do so. In 2019, six of the directors in office attended the annual meeting of stockholders.
The table below sets forth the number of meetings held by each committee and the full Board in 2019. All incumbent directors attended 75% or more of the aggregate meetings of the Board and committees on which they served during 2019.

Corporate Governance Guidelines
Our Board adopted Corporate Governance Guidelines that outline, among other matters, the roles and functions of the Board, the responsibilities of various Board committees and the mission of the Board. Our Corporate Governance Guidelines can be found at investor.ipgphotonics.com/governance/governance-documents. Information on our website does not constitute part of this Proxy Statement.
The Corporate Governance Guidelines provide, among other things, that:
a majority of our Board must be independent
the Presiding Independent Director presides over executive sessions of independent directors
the Board appoints all members and chairpersons of the Board committees
the Audit Committee, Compensation Committee, and NCGC consist solely of independent directors
the independent directors meet periodically in executive sessions without the employee directors or management
independent directors may not serve on the boards of more than three other public companies or, with the permission of the Board, four; the CEO may not serve on more than one other public company board
Board self-assessments are conducted annually and
the Board and key officers should have a meaningful financial stake in the Company.
The Board monitors changing legal and regulatory requirements, evolving best practices and other developments. The Board modifies the Corporate Governance Guidelines and its other corporate governance policies and practices from time to time, as appropriate.
Director Orientation and Continuing Education
The Board and its committees proactively monitor legislative and regulatory initiatives, as well as other corporate governance trends and their potential impact on the Company. The Board receives presentations from professionals with expertise in corporate law, governance and other related topics. These experts have specialized knowledge of regulatory actions, governance trends and various other corporate governance topics. In 2019, the Board and its committees received presentations on board oversight and stockholder engagement, SEC rulemaking, governance trends, critical accounting matter disclosures and cybersecurity. Additionally, our directors engage in continuing education to remain informed on recent trends applicable to their committee duties.
Likewise, newly elected directors attend a comprehensive director orientation program that covers, among other things, our strategy, business structure, financial performance, and competitive landscape. New committee members are also provided training on committee policies, practices and trends. As part of this program, directors are asked to tour facilities as appropriate. To further familiarize directors with our expanding operations, we conduct Board meetings at our major manufacturing facilities from time to time.
Board Performance Evaluations
The Board conducts annual self-assessments and its committees conduct bi-annual self-assessments to determine whether they are functioning effectively. Further, the performance of the Presiding Independent Director is evaluated annually. The NCGC oversees the Board and committee self-assessments. Each committee also reviews its own performance bi-annually and reports the results to the Board. Each committee reviews and reassesses the adequacy of its charter annually and recommends proposed changes to the Board.
Prohibition on Hedging; Limits on Pledging
Under our insider trading policy, no director or employee, including NEOs, may engage in shorting shares of our common stock; buying or selling puts, calls or derivatives related to our common stock or other Company securities, which includes equity compensation; or engaging in hedging transactions, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars and exchange funds. No director or officer, including NEOs, may pledge shares constituting more than 20% of his or her total stock ownership. Pledges of shares constituting 20% or less of total stock ownership are subject to certain conditions.

Communication with our Board of Directors
Interested parties wishing to write to the Board, a specified director or a committee of the Board should send correspondence to the Office of the Secretary, IPG Photonics Corporation, 50 Old Webster Road, Oxford, Massachusetts 01540. All written communications received in such manner from stockholders of the Company will be forwarded to the members or committee of the Board to whom the communication is directed or, if the communication is not directed to any particular member(s) or committee(s) of the Board, the communication shall be forwarded to all members of the Board.
Procedures for Submitting Complaints
We have procedures to treat complaints regarding accounting, internal accounting controls, auditing matters, fight against bribery, banking, and financial crime, including submission of confidential and anonymous concerns regarding questionable accounting, internal accounting controls or auditing matters raised by our directors, officers and employees. These procedures are posted on our website at investor.ipgphotonics.com/governance/governance-documents.
Transactions with Related Parties
The Board adopted a related person transaction policy that requires the NCGC to approve or ratify any transaction or series of transactions exceeding $100,000 in which our Company is a participant and any related person has a direct or indirect material interest (other than solely as a result of being a director or trustee or less than 10% owner of another entity) ("Related Party Transactions"). Related persons include our directors, director nominees and officers and their immediate family members and persons sharing their households. It also includes persons controlling more than 5% of our outstanding common stock. Subject to certain exceptions in the policy, related parties are required to notify the NCGC of the Related Party Transaction for an assessment of whether the transaction or proposed transaction should be permitted. Management also has established procedures for monitoring transactions that could be subject to approval or ratification under the Related Party Transactions policy.
In deciding whether to approve or ratify the Related Party Transaction, the NCGC considers relevant facts and circumstances. The committee will take into account, among other factors, whether the transaction is on terms no more favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction. Once a Related Party Transaction has been identified, the NCGC will review all of the relevant facts and circumstances and approve or disapprove entry into the transaction. Members of the NCGC having an interest in a transaction excuse themselves for the consideration and approval of the transaction in which they have an interest. Certain transactions are exempt from the policy including compensation paid by the Company for service as a director or an officer.
Pursuant to our Corporate Governance Guidelines, we expect each of our directors to ensure that other existing and future commitments do not conflict with or materially interfere with his or her service as a director. In addition, directors are required to inform the chairman of our NCGC prior to joining the Board of another public company to ensure that any potential conflicts, excessive time demands or other issues are carefully considered.
The NCGC reviewed and approved the following Related Party Transaction for 2019 in compliance with our policy:
Dr. Gapontsev leases the annual right to use 25% of the Company’s corporate aircraft under a July 2017 lease agreement (the “Aircraft Lease”) in connection with the purchase of an aircraft. The Aircraft Lease expires in July 2022. The annual lease rate under the Aircraft Lease is $924,700 and future rent payments are adjusted annually. Dr. Gapontsev paid the Company $923,712 in 2019 for use of the aircraft, and in addition, directly paid an unrelated flight management firm for the operating costs of his private use, including pilot fees, fuel and other costs.

Following our annual meeting of stockholders in 2019, we granted to non-employee directors their annual equity award: one-third of the award value (determined pursuant to ASC Topic 718) was granted as service-based stock options and two-thirds of the award value was granted as service-based restricted stock units ("RSUs"). The annual awards vest in a single installment on the earlier of the first anniversary of the date of grant or the next annual meeting of stockholders.
Upon election to the Board, each new non-employee director receives a grant (determined pursuant to ASC Topic 718) of $125,000 in stock options and $125,000 in RSUs vesting on the first anniversary of the date of grant subject to the director’s continued service on the Board.

The exercise price of the stock options is the closing market price of our common stock on the date of grant. Any director who retires after at least eight years of service on the Board will be entitled to full vesting of all options and RSUs then held by the director.
2020 Update.Based upon changes to Company-wide equity compensation practices approved for 2020 and based upon recommendations and data provided by the Compensation Committee's independent compensation consultant, Radford, the Board approved changes to the mix of equity-based compensation paid to non-employee directors. Effective after the 2020 Annual Meeting, non-employee directors will receive their entire annual equity award in RSUs. The aggregate amount of equity compensation and vesting conditions remain the same.

Proposal 1 Election of Nine Directors

Objectives of Director Compensation
Quality non-employee directors are critical to our success. We believe that the two primary duties of non-employee directors are to effectively represent the long-term interests of our stockholders and to provide guidance to management. As such, our compensation program for non-employee directors is designed to meet several key objectives:
Adequately compensate directors for their responsibilities and time commitments and for the personal liabilities and risks that they face as directors of a public company;
Attract the highest caliber non-employee directors by offering a compensation program consistent with those at companies of similar size, complexity and business character;
Align the interests of directors with our stockholders by providing a significant portion of compensation in equity and requiring directors to own our stock; and
Provide compensation that is simple and transparent to stockholders and reflects corporate governance best practices.
We also believe in aligning director compensation with stockholder interests. In 2019, approximately 80% of independent director compensation was at-risk by being subject to stock price performance.
Elements of Director Compensation
We believe that the following components of our director compensation program support the objectives above:
We provide cash compensation through retainers for Board and committee service, as well as additional cash retainers to the Presiding Independent Director and chairs of our standing Board committees. We do not provide Board and committee meeting fees. Compensating our directors in this manner simplifies the administration of our program and creates greater equality in rewarding service on committees of the Board. The additional retainers compensate directors for the additional responsibilities and time commitments involved with chairperson responsibilities.
We pay for, provide or reimburse directors for expenses, including business class travel, incurred to attend Board and committee meetings and director education programs.
Directors do not have a retirement plan.
Directors who are our employees receive no additional compensation for service on the Board.
Determining Director Compensation
Our Compensation Committee reviews our director compensation program periodically to confirm that the program remains appropriate and competitive and recommends any changes to our full Board for consideration and approval.
The Compensation Committee engaged Radford to provide a comprehensive review of compensation for non-employee directors in comparison to the same compensation peer group used for the Company’s executive compensation analysis. The analysis included review of cash retainer, initial and annual equity grants, vesting schedules, meeting fees for Board and committee service. After considering the analysis provided by Radford in early 2019, the Committee did not change non-employee director compensation from 2018.

PROCESS FOR DETERMINING NON-EMPLOYEE DIRECTOR COMPENSATION
     
1
p22_greyarrow.jpg

p22_greyarrow.jpg

The Compensation Committee engages independent compensation consultant to review compensation of non-employee directors as compared to peer group. 
The Compensation Committee evaluates independent compensation consultant report, compensation trends, and need to retain and attract high caliber non-employee directors consistent with comparable companies.

 The Board considers changes to non-employee directors compensation program recommended by the Compensation Committee. Approved changes generally take effect after disclosure in the proxy statement and the annual meeting of stockholders.
     
Director and Executive Officer Stock Ownership Guidelines
The Board adopted stock ownership guidelines to more closely align the interests of our directors and executive officers with those of our long-term stockholders. Under the guidelines, the following persons are expected to maintain a minimum investment in our common stock as follows:
Non-employee directors, the lesser of 3,000 shares or three times their annual cash Board retainer (excluding committee retainers);
The CEO, five times his annual salary; and
Senior executive officers, the lesser of 5,000 shares or one times their respective annual salaries.
Vested stock options and unvested RSUs count toward required stock ownership levels. Indirect ownership of shares through a separate legal entity counts toward fulfillment of the ownership guidelines. Ownership requirements are to be achieved no later than four years after the election as a director or as an executive officer, except that prior to such time the director or officer is expected to retain a certain portion of stock issued upon exercise of stock options or vesting of RSUs until the minimum ownership levels are attained. All directors and executive officers were in compliance with our stock ownership guidelines on December 31, 2019.
2020 Update: After a review of peer practices, the NCGC recommended and the Board approved, the following increased stock ownership requirements effective February 2020:
Non-employee directors, five times their annual cash Board retainer (excluding committee retainers); and
Senior executive officers, two times their respective annual salaries.
The CEO's stock ownership requirement was not changed. Also, vested stock options no longer count toward required stock ownership levels.

Advisory Approval of Our Executive Compensation
We are asking our stockholders to cast an advisory vote to approve the compensation of the Named Executive Officers as disclosed in this Proxy Statement in accordance with the requirements of Section 14A of the Exchange Act. This proposal gives our stockholders the opportunity to express their views on the design and effectiveness of our executive compensation program. As most recently approved by our stockholders in 2017, we submit this proposal for a non-binding vote on a triennial basis. At the annual meeting of stockholders in 2017, the last time this proposal was up for a non-binding, advisory vote, over 98% of stockholders voted in favor of our executive compensation practices as disclosed in our 2017 proxy statement.
Our compensation program is designed to be simple, effective and link pay to performance. It reflects the size, scope and success of IPG’s business as well as the responsibilities of our NEOs. We believe our compensation program strikes the appropriate balance between utilizing responsible, measured pay practices and effectively incentivizing our executives to dedicate themselves fully to value creation for our stockholders. We encourage you to read the Compensation Discussion and Analysis below and the compensation tables and narrative disclosures that follow for additional details about our 2019 executive compensation program for our NEOs, including information about 2020 compensation.
As an advisory vote, the results of this vote will not be binding upon the Board or the Company. However, the Compensation Committee and the Board value the opinions expressed by our stockholders on this proposal and will consider the outcome of the vote when making future decisions on the compensation of our NEOs.
Thus, the Company is submitting to stockholders the following resolution for their consideration and approval:
RESOLVED, that the stockholders approve, on an advisory basis, the compensation of the Company’s Named Executive Officers as disclosed in this Proxy Statement pursuant to the compensation disclosure rules of the Securities and Exchange Commission (including in the Compensation Discussion and Analysis, the accompanying compensation tables and related narrative).
The Board of Directors recommends that you vote FORapproval of our executive compensation.
Compensation Committee Report
The Compensation Committee of the Board has reviewed and discussed with management the Compensation Discussion and Analysis included in this Proxy Statement. Based on this review and discussion, the Compensation Committee recommended to the Board that the Compensation Discussion and Analysis be included in the Company’s Proxy Statement for the Company’s 2020 Annual Meeting of Stockholders and in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

Financial and Strategic Highlights of 2019
We shipped a record number of high power lasers in 2019 and increased sales of lasers at 10 kilowatts or greater by more than 25%. However, given weaker industrial demand trends resulting from escalation of the US-China trade conflict and macroeconomic challenges in our largest regions, revenue in 2019 decreased by 10%. As we enhance our capability in providing complete laser solutions to end customers, we sold a record number of laser systems for materials processing in 2019. Furthermore, we are leveraging one of the largest R&D investments in the laser industry to launch leading edge products, and in 2019 new product sales were 19% of total revenue. Because of lower absorption of fixed costs in our vertically-integrated production model, lower product pricing, foreign exchange headwinds and other factors, our industry-leading gross margin declined to 46%. We delivered operating cash flow of $324 million in 2019 and maintain one of the strongest balance sheets in the industrial automation industry, with more than $1 billion net cash and ample liquidity at December 31, 2019.
2019 Executive Compensation Highlights and Changes to 2020 Compensation Program
The Compensation Committee held 2019 executive base salaries, target annual incentives and long term equity incentives at 2018 levels, reflecting the global macroeconomic environment existing at the start of 2019. Financial performance fell short of targets in 2019, which resulted in no 2019 annual incentive payouts for financial performance. Variable cash compensation opportunity is based upon annual net sales and profitability against threshold, target and maximum performance goals. Our NEOs earned a smaller payout based upon their individual performance evaluation as they undertook operational improvements to reduce expenses and increase cash flow as the demand downturn continued.
In 2019, our equity-based award program for executives included service-based stock options, service-based RSUs, and performance-based stock units ("PSUs"), with each award type representing approximately one-third of the overall 2019 long-term incentive opportunity (at target for the PSUs). In 2019, the Compensation Committee changed the index against which the relative performance of the Company’s stock is measured for the 2019 PSU awards to the S&P Composite 1500 Electronic Equipment, Instrument and Components Index (“S&P Electronics Index”) because this index has a higher overall correlation among constituents with the Company, and because the Company’s market cap, revenue and volatility are more in line with the range of such measures in the S&P Electronics Index as compared to the Russell 3000 Index used for prior years. IPG is a member of the S&P Electronics Index. Also in 2019, the Compensation Committee modified executive employment agreements allowing the Company to terminate employment for cause if the executive violates the Company’s Code of Business Conduct, and placing limits on certain outside activities without consent of the Board.
For 2020, executive base salaries and target annual incentives remain at 2018 levels; however, changes were made to the amount of equity incentives provided to Dr. Scherbakov and Mr. Mammen. Consistent with our pay-for-performance philosophy, the Compensation Committee modified our executive equity-based award program increasing the percentage of performance-based awards, which will now include an award based upon an operating metric. The Compensation Committee approved 2020 awards comprised of service-based RSUs (50%), and PSUs based upon relative total stockholder return (at target, 25%), and operating cash flow (at target, 25%).

IPG continued its net sales and income growth“say-on-pay” advisory vote, voting 98% in 2016, finishing another record year, while we continued to make investments for the future.
In 2016, we:
continued strong sales growth at 12% in 2016 and achieved a four-year compounded annual growth rate of 16%,

Executive Compensation Best Practices
PRACTICES WE EMPLOYPRACTICES WE AVOID
üAlign our NEO Pay with Performance: Strong links of compensation to Company performance and stockholder returns for annual and long term incentives. Annual bonus tied to revenue and net income and long term incentives include performance-based stock units which are earned based upon IPG’s total stockholder return relative to a broad stock market index and stock options which have value only if the stock price increases over the grant date price.
üBalance Annual and Long-Term Incentives: Incentive programs provide an appropriate balance of annual and long-term performance, alignmentincentives and include multiple measures of performance.
üUse Long-Term Incentives to stockholders'Link Executive Pay to Company Performance: Approximately 74% of NEO (other than the CEO) pay consists of long-term incentives linked to increasing our stock price. CEO receives no equity.
üCap Incentive Award Payouts: Annual incentive plan award payouts and certain long-term incentive awards are capped.
üMaximize Stockholder Value While Mitigating Risk: Service-based equity awards vest over four years. This incentivizes long-term growth and discourages short-term risk taking.
üIndependent Compensation Consultant: The Compensation Committee retains a compensation consultant, who is independent and without conflicts of interest with the Company.
üRobust Stock Ownership Requirements: Officers and directors are subject to stock ownership guidelines to further align their interests with stockholder interests. Our NEOs substantially exceed the ownership guidelines.
üClawbacks on Executive Compensation: We adopted a compensation recovery policy covering cash and equity.
ûNo Guaranteed Annual Bonuses: Our annual incentive compensation plan is performance-based and does not include any minimum payout levels.
ûNo Retirement Benefits: We have no supplemental executive retirement plans (SERPs) or defined benefit pension plans.
ûNo Tax Gross-Ups: We do not provide tax gross reimbursements for change in control payouts or executive perquisites.
ûNo Significant Perquisites: We provide limited perquisites to our NEOs.
ûHedging of Company Stock is Prohibited.
ûNo Severance For “Cause” Terminations.
ûNo Single-Trigger Change in Control Provisions. Equity awards for NEOs generally require a “double-trigger” of both a change-in-control and termination of employment for both cash and equity compensation acceleration.
ûNo Stock Option Repricing without Stockholder Approval. Our equity plans prohibit repricing underwater stock options.
û Pledging of Company stock is limited.

Proposal 2 Advisory Approval of Our Executive Compensation

2019 Compensation of Named Executive Officers
Our Business and Our Compensation Philosophy
The guiding principles of our executive compensation philosophy and practices continue to be pay-for-performance, accountability for annual and long-term performance, alignment to stockholders’ interests, and providing competitive pay to attract and retain executives. We believe our compensation program strikes the appropriate balance between utilizing responsible, measured pay practices and effectively incentivizing our executives to dedicate themselves fully to value creation for our stockholders.
Our executive compensation program is designed to focus our executive officers on both annual and long-term financial and operational performance without encouraging unnecessary risk. The following graphs show that approximately 22% of the CEO’s total direct compensation and approximately 78% of the average total direct compensation of all of the other NEOs’, as reflected in the 2019 column of the Summary Compensation Table, is at risk.
Our CEO, the Company’s founder, does not receive long-term incentive compensation because of his significant level of common stock ownership which the independent directors believe provides him with sufficient incentives to act in the best long-term interest of our stockholders. As a result, a smaller percentage of his total compensation is performance-based as compared to the chief executives of our peer companies who typically receive additional compensation in the form of substantial long-term incentives.

Base Salary
We provide base salary to our Named Executive Officers and other employees to compensate them for services rendered on a day-to-day basis during the fiscal year. Unlike annual cash incentives and long-term equity incentives, base salary is not subject to performance risk. The Compensation Committee reviews information provided by its compensation consultant and considers the experience, skills, knowledge and responsibilities of the executive and the individual's performance assessment provided by the Chief Executive Officer to assist it in evaluating base salary for each Named Executive Officer. With respect to the Chief Executive Officer, the Compensation Committee additionally considers the performance of the Company as a whole.
In 2016, the Compensation Committee evaluated the base salaries and total cash compensation for the Named Executive Officers with the assistance of Radford. The Compensation Committee reviewed Radford's assessment in connection with positioning the midpoint of the Company's target total cash compensation range near the 65thpercentile of our peer group. Based upon this review, the Compensation Committee approved increases of the Named Executive Officers in the following manner; Dr. Gapontsev received an increase in base salary of 11% bringing his base salary in line with the market 65th percentile of our peer group. In addition, the salary of Dr. Scherbakov was increased from approximately $452,900 to $500,000 bringing his base salary within the competitive range of the target market 65th percentile. Messrs. Mammen and Ness and Dr. Ovtchinnikov also received increases to their base salaries of 3%.

Update 2017. In 2017, the Compensation Committee approved merit increases of 5% to the 2016 base salaries of Mr.Mammen and Dr. Ovtchinnikov, following an assessment of base salaries and total cash compensation conducted by Radford. Mr. Ness’s base salary increased by 8%. The CEO's base salary was increased 13% to $832,000, bringing his base closer to the target market 65th percentile. Likewise, the salary

33





of Dr. Scherbakov increased from approximately $500,000 to $540,000 in consideration of his additional management responsibilities related to his appointment as Chief Operating Officer in February 2017.
2016 Cash Incentive Awards
To focus each executive officer on the importance of the Company's performance, a significant portion of the individual's potential short-term compensation is in the form of annual cash incentive pay that is tied to the achievement of goals set by the Compensation Committee. Our Named Executive Officers participate in our Senior Executive Annual Incentive Plan (the "AIP") administered by the Compensation Committee. The Compensation Committee determines who is eligible to receive awards under the AIP, defines performance goals and objectives for executives, establishes target awards for each participant for the relevant performance period, and determines the percentage of the target award that should be allocated to the achievement of each of the chosen performance goals in consultation with the Chief Executive Officer with respect to other executive officers. The target award percentages established by the Compensation Committee are chosen with input from the compensation assessment conducted by Radford and the seniority level of the executive.
Consistent with prior years, in 2016 the Compensation Committee identified two financial performance measures: net sales and adjusted EBIT and assigned a 50% weighting factor to each financial performance goal. "Adjusted EBIT" is a performance measure that is equal to our earnings before interest income and expense, income taxes, equity-based compensation expenses and expenses for certain litigation matters approved by the Compensation Committee. Further, the Compensation Committee intentionally focused on net sales growth and pretax profits so that our executive officers would be incentivized to deliver the types of growth that benefit our stockholders, namely increasing sales and profits.
Under the 2016 AIP, the executives could receive cash incentive payments in the table below as a percentage of base salaries based upon achievement of the minimum to maximum objectives for both financial performance measures and for individual performance. If the financial performance exceeds one or more of the maximum objectives, the incentive payments to the executive would increase as determined by linear interpolation, subject to limits on award payouts. Consistent with our pay-for-performance philosophy, no cash incentive payments would be made if the minimum financial objectives established by the Compensation Committee in 2016 were not met. The individual goals and objectives for the Chief Executive Officer include operational and strategic targets determined by the independent directors.
The overall target awards in the table below are a percentage of the respective base salaries. The company-wide financial objectives are the same for all executive officers in order to foster a shared commitment among executives.

(1)Target Awards include both financial and individual performance targets.

While objectives were intended to be achievable by the Company, a maximum bonus would require very high levels of Company performance. The Compensation Committee adjusted the targets in 2016 to reflect the acquisition of Menara Networks, Inc. in May 2016 and to exclude the effect of an impairment charge for a long-lived asset. The Compensation Committee's adjusted minimum and maximum targets for net sales were $873 million and $1,181 million, respectively, representing an increase of 16.7% for both the minimum and maximum targets from the prior year. The minimum and maximum targets for Adjusted EBIT were set from $314 million to $473 million, representing an increase to the minimum and maximum targets of 15.2% and 15.5%, respectively. The adjusted target levels for net sales and Adjusted EBIT were $1,027 million and $393 million, respectively.

34





During 2016, the Company achieved net sales of $1,006 million and Adjusted EBIT of $394 million. These results represent a 12% increase in net sales and a 9% increase in Adjusted EBIT over 2015 levels.  However, the Company's financial performance for 2016 was slightly below the net sales target and was slightly above the Adjusted EBIT target. The independent directors set the individual goals and objectives for the Chief Executive Officer in 2016. The Compensation Committee reviewed the Chief Executive Officer's attainment of the goals and objectives (with input from the independent directors) in early 2017 and awarded him 25.0% of his base salary for his individual performance during 2016. Also, the Compensation Committee, with input from the Chief Executive Officer, awarded Dr. Scherbakov and Messrs. Mammen and Ness 19.0%, and Dr. Ovtchinnikov 16.7%, of their respective base salaries for their individual performances in 2016.

The Compensation Committee may award discretionary bonuses to executives for exceptional performance. For 2016, the Compensation Committee did not exercise this right.
Equity-Based Incentives Granted in 2016
The goal of our equity-based award program is to provide employees and executives with the perspective of an owner with a long-term financial stake in our success, further increasing alignment with stockholders. Our equity-based incentives align the interests of our executives and stockholders by motivating executive officers to increase long-term stockholder value.

In 2016, our equity-based award program for executives included service-based stock options (33%), service-based restricted stock units (33%), and performance-based stock units (at target, 33%). These grants reflected a 2015 review by our Compensation Committee with the assistance of Radford of grant practices at peer companies. The value of stock options, restricted stock units and performance-based stock units are tied to the Company stock price which links pay to performance.

Consistent with our pay-for-performance philosophy, the service-based stock option awards have no value unless our stock price increases after the grant date. Another reason why we use service-based stock options is because it fosters an innovative environment focused on long-term growth of the Company and stockholder value. With respect to the performance-based stock units, the Compensation Committee decided to measure performance of the Company's stock as compared to the Russell 3000 Index, which includes the Company. The addition of performance-based stock units in 2015 to the equity mix increases the portion of the executives' compensation that is based upon the Company's performance. Also, it directly aligns executives' compensation with stockholders interest because the number of shares earned depends upon performance against the Russell 3000 Index and the value of the shares fluctuates based on the stock price. For each 1% that IPG's common stock exceeds the performance of the Russell 3000 Index for the trailing 60 trading days from the end of the performance measurement period (March 1, 2019) against the comparable period from the beginning of the performance measurement period (March 1, 2016), the grant recipient would receive a 2% increase in the number of shares above target (up to a maximum cap of 200% of the target award). For each 1% below the Russell 3000 Index's performance, the grant recipient would receive a 2% decrease in the number of shares (down to zero). The vesting date is March 1, 2020, should any performance-based stock units vest at all.

In 2016, the Compensation Committee targeted granting equity compensation near the 65th percentile of the target compensation of our peer group, balancing the perspective of delivering competitive compensation based upon Black-Scholes option pricing values. The Compensation Committee analyzed several aspects of the equity grant program, including (i) the "in the money" value, the degree to which executives have incentives to remain employed by the Company through unvested option values, and (ii) the aggregate equity usage in terms of (a) annual usage, typically called burn rate, and (b) cumulative equity delivery, typically called overhang, to determine the dilutive effect of equity awards on investors. The majority of outstanding equity award holdings of the executives were allocated to unvested shares in the aggregate, and all such executives had a minimum of four years' worth of annual award values in unvested equity value. Based upon this information, Radford advised the Compensation Committee that our equity program provides strong retention incentives.
Since the Company's initial public offering in 2006, the Compensation Committee has not granted the Chief Executive Officer any equity compensation awards. As the Company's founder and the beneficial

35





owner of a large number of our shares, he has the perspective of an owner with a significant financial stake in the Company's success. This practice has resulted in substantially lower total compensation earned by our Chief Executive Officer as compared to the chief executives of our named peers despite our outstanding business and earnings growth. In addition, this practice results in a lower compensation expense and lower equity burn rate for the Company.
The table below provides information on grants of service-based stock options, service-based restricted stock units and performance-based stock units to the Named Executive Officers in 2016. All awards in the table below vest on March 1, 2020.

The Compensation Committee believes that four-year vesting for annual awards provides a strong incentive for executives to remain employed by us and to focus on increasing our financial performance over the long-term, while discouraging excessive short-term risk taking. The service-based restricted stock units granted in 2016 may be entitled to dividends, should any be paid, at the discretion of the Compensation Committee. Any dividends on shares underlying the performance-based stock units,s do not vest until the performance-based stock units,s vest.

2017 Update. The Compensation Committee approved the grant of service-based stock options, service-based restricted stock units and performance-based stock units to the Named Executive Officers in February 2017. All equity awards in the table below vest according to the revised vesting schedule approved by the Compensation Committee: stock options and service-based restricted stock units vest 25% on each anniversary of March 1, 2017 and performance-based stock units vest on March 1, 2020, the last day of the performance period which is three years after the start of the performance period on March 1, 2017.

Severance Benefits.The severance benefits we offer assist us in recruiting and retaining talented individuals and are consistent with the range of severance benefits offered by our peer group. The severance provisions of our employment agreements are summarized below in the section titled "Potential Payments upon Termination or Change in Control."
Retirement Benefits.We do not offer an executive retirement plan or a non-qualified deferred compensation plan. Executive officers in the United States are eligible to participate in our 401(k) retirement savings plan on the same terms as all other U.S. employees. Our 401(k) retirement savings 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 made matching contributions to our employees at a rate of 50% of deferrals subject to a maximum of 6% of eligible compensation under the 401(k) retirement savings plan, including the Named Executive Officers, who participate in the plan as set forth in the Summary Compensation Table. Our executives outside of the United States participate in government-sponsored retirement programs.

Base Salary
We provide base salary to our NEOs and other employees to compensate them for services rendered on a day-to-day basis during the fiscal year. Unlike annual cash incentives and long-term equity incentives, base salary is not subject to performance risk. The Compensation Committee reviews data provided by its compensation consultant and considers the factors when setting base salaries of the NEOs: experience, skills, seniority, knowledge and responsibilities of the executive and the individual’s performance assessment provided by the CEO. With respect to the CEO, the Compensation Committee additionally considers the performance of the Company as a whole in its recommendation to the independent directors, who set CEO compensation.

Proposal 2 Advisory Approval of Our Executive Compensation

In 2019, the Compensation Committee evaluated the base salaries and total cash compensation for the NEOs with the assistance of Radford, its independent compensation consultant. Due to the challenging macroeconomic and foreign trade conditions beginning in 2018 and continuing into 2019, the independent directors accepted the Compensation Committee’s recommendation to not increase the base salary of the CEO and the Compensation Committee concurred with the CEO’s recommendation to not increase the base salaries of the other NEOs in 2019.
Annual Incentives
To focus each NEO on the importance of the Company’s performance, a significant portion of the individual’s potential short-term compensation is in the form of annual cash incentive pay that is tied to the achievement of goals set by the Compensation Committee. Our NEOs participate in our Senior Executive Annual Incentive Plan (the “AIP”) administered by the Compensation Committee. The Compensation Committee determines who is eligible to receive awards under the AIP, defines performance goals and objectives for executives, establishes target awards for each participant for the relevant performance period, and determines the percentage of the target award that should be allocated to the achievement of each of the chosen performance goals in consultation with the CEO with respect to other executives.

Non-GAAP “Adjusted EBIT” is an internally defined performance measure that is derived from GAAP net income by adding back the provision for income taxes, interest expense and do not discriminate in favorstock-based compensation expenses and deducting interest income.
Under the 2019 AIP target approved by the Compensation Committee in February 2019, the NEOs could receive cash incentive payments as a percentage of their base salaries based upon Company performance relative to the financial performance goals. Under the 2019 AIP, if a performance goal is met at the target level as determined by the Compensation Committee, the target bonus is paid for that goal. Performance above target results in a payout of a higher percentage of salary, up to 200% of the NEO’s target cash bonus. Performance below target results in a lower bonus payout for that goal if a minimum threshold is met, with 18.75% of the NEO’s target cash bonus as the minimum in such circumstance, or no payout if the minimum threshold is not met. At target, the financial performance payout accounts for 75% of the overall target award. The CEO and COO can earn up to 25% of their respective target awards based upon goals and objectives determined by the independent directors. For 2019, targets included strategic planning and execution, executive development, inventory management and business growth drivers. The other NEOs also are eligible for payouts up to 25% of the target award based on their individual performance and other factors the Compensation Committee deems relevant.

Revenue in 2019 was $1,315 million and adjusted EBIT in 2019 was $312 million, both of which were below the threshold performance required for a payout based on financial performance. At the beginning of 2019, the Compensation Committee set aggressive goals for management based upon improving business conditions seen in late 2018 and early 2019. However, the expected improvements did not materialize as the Company faced worsening conditions from escalations in the U.S.-China trade war in the second quarter, including escalating tariffs and increased customer uncertainty. Continuing macroeconomic challenges in 2019 affected capital equipment purchases in Europe and China, our two largest regions. The impact of increased price competition together with lower industrial machinery purchasing activity adversely affected both revenues and earnings. Each NEO earned the full payouts with respect to the individual performance component as they took undertook operational improvements to reduce expenses and increase cash flow as increased competition and the demand downturn continued. NEOs also guided continued investments in and development of new products.

Benefits are intendedtarget. As noted above, the NEOs received payouts only with respect to be competitive with the overall market in order to facilitate attraction and retention of high-quality employees. The Compensation Committee compared the Company's executive perquisites against the 2016 peer group and made no changes . The Company provides the use of a corporate aircraft to the Chief Executive Officer and other executivesindividual performance for business travel integral to the performance of their duties. Executives are encouraged to use the aircraft for efficiency, safety and security. However, executives are not allowed to use the aircraft for unreimbursed personal use but family and other guests may accompany executives on the aircraft for business travel. The Company provides the Chief Executive Officer with a car and driver in the United States so that he may use his travel time for company purposes. The Company also provides Dr. Scherbakov use of an automobile, as it does for other high-ranking employees in Germany.2019.
None of the NEOs' target bonus percentages were increased in 2019 or 2020.
Long-Term Incentives
The goal of our equity-based award program is to provide employees and executives with the perspective of an owner with a long-term financial stake in our success, further increasing alignment with stockholders. Our equity-based incentives align the interests of our executives and stockholders by motivating executives to increase long-term stockholder value.
In 2019, our equity-based award program for our NEOs (other than our CEO) included service-based stock options, service-based RSUs, and PSUs, with each award type representing approximately one-third of the overall 2019 long-term incentive award opportunity (at target for the PSUs). The type and proportion of the equity grants reflected a 2019 review by our Compensation Committee with the assistance of Radford of grant practices at peer companies. The value of stock options, RSUs and PSUs are tied to the Company's stock price which links pay to performance.
Consistent with our pay-for-performance philosophy, the service-based stock option awards have no value unless our stock price increases after the grant date.
The Compensation Committee believes that vesting of awards of service-based options and RSUs over four years provides a strong incentive for executives to remain employed by us and to focus on increasing our financial performance over the long-term, while discouraging excessive short-term risk taking. The Compensation Committee believes that PSUs should vest over three years, rather than four years, because having a four-year performance period would reduce the utility of the performance award and not properly align pay with performance. Service-based RSUs granted in 2019 may be entitled to dividends, should any be paid, at the discretion of the Compensation Committee. Any dividends on shares underlying the PSUs do not vest until the PSUs vest.

Proposal 2 Advisory Approval of Our Executive Compensation

In 2019, the Compensation Committee used competitive market data from the total compensation study of peer companies, balancing the perspective of delivering competitive compensation based upon Black-Scholes option pricing values and Monte Carlo simulations for PSUs. The Compensation Committee analyzed several aspects of the equity grant program, including (i) the “in the money” value, the degree to which executives have incentives to remain employed by the Company through unvested option values, and (ii) the aggregate equity usage in terms of (a) annual usage, typically called burn rate, and (b) cumulative equity delivery, typically called overhang, to determine the dilutive effect of equity awards on investors. The majority of outstanding equity award holdings of the executives were allocated to unvested shares in the aggregate, and all such executives had a minimum of two years’ worth of annual award values in unvested equity value. Based upon this information, Radford advised the Compensation Committee that our equity program provides strong retention incentives.
Since the Company’s initial public offering in 2006, the Compensation Committee has not granted the CEO any equity compensation awards. As the Company’s founder and the beneficial owner of a large number of our shares, he has the perspective of an owner with a significant financial stake in the Company’s success and a long-term outlook. This practice has resulted in substantially lower total compensation earned by our CEO as compared to the chief executives of our named peers despite our outstanding business and earnings growth over the long term. In addition, this practice results in a lower compensation expense and lower equity burn rate for the Company.
For the 2019 PSU awards, the Compensation Committee changed the index against which the relative performance of the Company’s stock is measured. The Compensation Committee considered the analysis of Radford with respect to the current peer index, the Russell 3000, and other peer index alternatives. The Committee selected the S&P Composite 1500 Electronic Equipment, Instrument and Components Index (“S&P Electronics Index”) as the 2019 relative stock index for the PSUs in part because it has a higher overall correlation among constituents with the Company, and the Company’s market cap, revenue and volatility are in line with the range of such measures in the index. IPG is a member of the index. This directly aligns executives’ compensation with stockholders interest because the number of shares earned depends upon performance against the S&P Electronics Index and the value of the shares fluctuates based on the stock price. For each 1% by which the Company's common stock exceeds the performance of the S&P Electronics Index for the trailing 60 trading days from the end of the performance measurement period (March 1, 2022) against the comparable period from the beginning of the performance measurement period (March 1, 2019), the grant recipient would receive a 2% increase in the number of shares above target (up to a maximum share cap of 200% of the target award).
For each 1% by which the Company's common stock falls below the S&P Electronics Index’s performance, the grant recipient would receive a 2% decrease in the number of shares (down to zero). In addition, NEOs cannot receive a number of shares that exceeds 600% of the value of the target award on the date of grant.
The table below provides information on grants of service-based stock options, service-based RSUs and PSUs to the NEOs in 2019. All awards in the table below vest 25% on each anniversary of March 1, 2019, except for the PSUs, which vest on March 1, 2022, the last day of the three-year performance measurement period.

Other Compensation
Severance Benefits.The severance benefits that we offer to our NEOs assist us in recruiting and retaining talented individuals and are consistent with the range of severance benefits offered by our peer group. The severance provisions of our NEO employment agreements are summarized in Potential Payments upon Termination or Change in Control below.
Retirement Benefits. We do not offer an executive retirement plan or a non-qualified deferred compensation plan. Executives in the United States are eligible to participate in our 401(k) retirement savings plan on the same terms as all other U.S. employees. Our 401(k) retirement savings 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 NEOs). We made matching contributions to our employees at a rate of 50% of deferrals subject to a maximum of 6% of eligible compensation under the 401(k) retirement savings plan, including the NEOs, who participate in the plan as set forth in the Summary Compensation Table. Dr. Scherbakov, who resides in Germany, participates in a German government-sponsored retirement program.

Personal Benefits. Our executives are eligible to participate in employee benefit plans, including medical, dental, life and disability insurance and vacation plans as well as an employee stock purchase plan, which is intended to be qualified under Section 423 of the Code. The employee stock purchase plan allows participants to purchase Company shares at a price equal to 85% of the lesser of the fair market value at the first day or last day of the six month offering period, subject to limitations on the amount of shares. These plans generally are available to all salaried employees and do not discriminate in favor of executives. Benefits are intended to be competitive with the overall market in order to facilitate attraction and retention of high-quality employees.
The Compensation Committee compared the Company’s executive perquisites policies against the 2019 peer group and made no changes. The Company provides the use of a corporate aircraft to the CEO and other executives for business travel integral to the performance of their duties. Executives are encouraged to use the aircraft for efficiency, safety and security. However, executives are not allowed to use the aircraft for personal use that has not been paid for, except that family and other guests may accompany executives on the aircraft for business travel. The Company provides the CEO with a car and driver in the United States so that he may use his travel time for company purposes. The Company also provides Dr. Scherbakov use of an automobile, as it does for other high-ranking employees in Germany.
Executive Compensation Decision-Making
Role of Compensation Committee
The Compensation Committee determines, approves and administers the compensation programs for our executive officers, including our Named Executive Officers.NEOs. The Compensation Committee recommends to the independent directors the CEO’s annual base salary, annual incentive opportunity and long-term incentive opportunity. The independent directors approve the CEO’s compensation and our Compensation Committee approves the compensation for other executive officers in consultation with our CEO. Our Compensation Committee is also responsible for making recommendations to the Board with respect to the adoption of equity plans and certain other benefit plans. The Compensation Committee and the independent directors meet in executive decisions when determining executive compensation.
The Compensation Committee may delegate authority whenever it deems appropriate. In 2016,2019, the Compensation Committee delegated authority to grant equity awards for non-executive officersnon-executives to the Chief Executive OfficerCEO, subject to certain conditions, including amounts of awards and review of awards by the Compensation Committee.
Our Compensation Committee'sCommittee’s policy is to set executive officer pay in accordance with the objectives of the Company'sCompany’s compensation programs as described above. In the Compensation Committee'sCommittee’s view, the Company'sCompany’s executive compensation program provides an overall level of compensation opportunity that is competitive with peer companies. Actual compensation levels may be greater or less than target compensation levels provided by similar companies based upon short-termannual and long-term Company performance, as well as individual performance, contributions, skills, seniority, knowledge, experience and responsibilities.

Role of Independent Consultant

The Compensation Committee engaged Radford, an independent compensation consultant, to conduct a comprehensive review and analysis of our executive and non-employee director compensation programs and to make recommendations for compensation related to 2016.2019. The consultation included non-executive compensation data and valuation services for equity incentives. Radford’s parent company, Aon Hewitt, does not perform any other work for the Company. The Compensation Committee reviews the independence of Radford in light of SEC rules and NASDAQNasdaq listing standards regarding compensation consultants. The Compensation Committee believes that there were no actual or potential conflicts of interest with Radford in 2016.2019.

Pay Positioning Strategy and Peer Group

In 2016,Consistent with prior years, in 2019 the midpoint of the Company's target total cash compensation range was adjusted to near the 65thpercentile. The Compensation Committee also increasedused competitive compensation data from the long-term incentive range to near the 65th percentile as a result of management’s strong performance in 2016 and also to align the long-term incentive range with the market.

These adjustments have positioned our targetedannual total compensation competitively within ourstudy of peer group. An individual's actualcompanies to inform its decisions about overall compensation may fall below or aboveopportunities and specific compensation elements. Additionally, the target positions based onCommittee used multiple reference points when establishing targeted compensation levels. Within the individual's experience, seniority, skills, knowledge, performance, responsibilities and contributions as well ascomparative framework, the Company's performance. These factors are weighedprimary data was the named peer group of specific peers selected by the Compensation Committee and the secondary data was broader, size-appropriate comparisons in itsthe high technology industry using Radford High Technology Survey Data. The Committee does not benchmark specific compensation elements or total compensation to any specific percentile relative to the peer companies or the broader United States market. Instead, the Committee applies judgment and nodiscretion in establishing targeted pay levels, taking into account not only competitive market data, but also factors such as Company, business and individual performance, scope of responsibility, critical needs and skill sets, leadership potential and succession planning. No single factor takes precedence over othersany other, nor is any formula used in making these decisions.
In analyzing our executive compensation program relative to this target market positioning, the Compensation Committee utilizes a comparative analysis of the compensation of our executive officers measured against a group ofThe peer companies selected by the Compensation Committee. The peer companiesCommittee are companies that operate in the laser sourcesemiconductor equipment and photonics industry, as well as a broader groupelectronic manufacturing industries, and are comparable in terms of technology companies of comparable sizerevenue, market capitalization and complexity that have similar growth rates and international scopes.headcount.

The Compensation Committee reviews this peer group annually with input from Radford to ensure that the comparisons are meaningful. In this review, the Compensation Committee considers several factors in developing a peer group: it considers the current peer group to determine appropriateness, the peers used by institutional governance advisors, the companies that list our company as a peer to understand crossover peers and broader research based upon established selection criteria to identify potential future peers. The Committee then develops criteria for business sector, revenue, market capitalization revenue and headcount. Radford also supplements its peer analysis with the data from a broader list of high-technology public company participants in the AON Radford Executive Technology Survey targeting technology companies with comparable revenue levels. Companies that are no longer publicly traded have beenare omitted from the peer group. Based upon the process and applying the criteria above, the Compensation Committee (i) added Barnes Group, Inc., OSI Systems, Inc., National Instruments, Inc., Nordson Corporationapplied the methodology above and Zebra Technologies, Inc. todetermined the peer group and (ii) removed Chart Industries, Inc., Newport Corporation, RBC Bearings Inc., Riverbed Technology, Inc. and Veeco Instruments, Inc. from the peer group.approved for 2018 continued to be appropriate for 2019.

COMPANY VS. PEER GROUP
p45_peergroupgraphic.jpg
2020 Update.For 20172020 compensation determinations, the Compensation Committee appliedreviewed the methodology aboveanalysis from Radford regarding the Company’s peer group. Radford performed an analysis of similarly-situated public companies, supplemented the peer group with published survey data providing a broad market representation of companies and removed Analogic Corporation, Brooks Automation,deeper position reporting, as well as set parameters for the peer group study. For 2020, the analysis by Radford proposed adding Watts Water Technologies. Inc. (industrial machining) and Lumentum Holdings Inc. (communications networks and lasers), Diodes, Inc., FEI Company and Rofin-Sinarremoving Zebra Technologies Inc.(electronics equipment and instruments) and Arista Networks (communications networks) because such peers fell below the targeted scope of one or more of market values, revenues and headcount or were acquired. Additionally, thetheir different business focuses. The Compensation Committee added Dolby Laboratories, Inc., Fabrinet, IDEX Corporation, ITT, Inc. and Trimble Navigation Limitedapproved the proposed changes to the peer group for 2017.2020 compensation determinations.
Other Factors Affecting Compensation
Tax Deductibility under Section 162(m). Section 162(m) of the Internal Revenue Code ("(“Section 162(m)"), limits the deductibility for federal income tax purposes of certain compensation paid in any year by a publicly held corporation to its chief executive officer“covered employees” as defined by Section 162(m) (generally, our current and its three other most highly compensated officers other than its chief financial officerformer NEOs) to $1 million per executive (the "$“$1 million cap"cap”). ThePrior to the enactment of the Tax Cuts and Jobs Act (“TCJA”), Section 162(m) provided an exception from this deduction limitation for certain forms of “performance-based compensation,” which included annual incentive pa youts, the gain recognized by NEOs upon the exercise of stock options and the income recognized on the vesting of performance share awards. Due to the TCJA, the “performance-based” compensation exception to the $1 million cap does not apply to "performance-based" compensation as defined under Section 162(m). The Compensation Committee's policy with respect to Section 162(m)for tax years after 2017, unless certain limited transition relief is to consider the tax deductibility of awards as a factor in the compensation setting process while providing our executive officers with appropriate rewards for their performance.met. The Compensation Committee retains the discretion to providegrant or pay compensation that may exceedexceeds the $1 million cap or may not qualify for the performance-based compensation exception to Section 162(m). The Compensation Committee believes it is appropriate to retain the flexibility to authorize payments of compensation that may not qualify for deductibility if, in the Compensation Committee’s judgment, it is in the Company’s best interest to do so. In the past, the Compensation Committee generally sought to structure performance-based compensation for our covered employees, and to undertake the required ministerial actions, in a manner that complies with Section 162(m) in order to provide for the deductibility of such compensation to the extent possible. We generally will continue to emphasize performance-based compensation, even though it may no longer be deductible.
Accounting Considerations. We consider the accounting implications of our executive compensation program. In addition, accounting treatment is just one of many factors impacting plan design and pay determinations. Our executive compensation program is designed to achieve a favorable accounting and tax treatment as long as doing so does not conflict with the intended plan design or program objectives.

Compensation Risk
Management conducts an annual risk assessment of the Company'sCompany’s compensation policies and practices for all employees, including non-executive officers,non-executives, and reports its findings to the Compensation Committee. In 2016,2019, management concluded that the Company'sCompany’s compensation policies and practices are balanced and do not motivate imprudent risk taking. Management believes that IPG’sthe Company's compensation policies do not create risks that are reasonably likely to have a material adverse effect on IPG.the Company.
In reaching this conclusion, they considered the following factors:
our compensation program is designed to provide a mix of both fixed and variable incentive compensation,compensation;
our senior executives are subject to stock ownership guidelines, which we believe incentivize our executives to consider the long-term interests of the Company and our stockholders and discourage excessive risk-taking that could negatively impact our stock price andprice;
our senior executives are subject to compensation recovery policy, which discourages excessive risk-taking that could negatively affect our stock price;
our incentive compensation programs are designed with vesting terms that are relatively consistent, spread out over several years, and do not contain steep payout "cliffs"“cliffs” that might encourage short-term business decisions in order to meet a vesting or payout threshold.threshold; and
our senior executive incentive compensation program caps the amounts that may be paid for performance above target level.
Other Policies
Anti-Hedging and Limitations on Pledging of Company Stock.The Board adopted policies prohibiting hedging transactions and limiting the pledging of our common stock. Under our insider trading policy, no director or employee may engage in shorting shares of our common stock or any type of securities that we may issue, or buying or selling puts, calls or derivatives related to our common stock. A director or officer of the Company may not pledge shares constituting more than 20% of his or her total stock ownership. Pledges of shares constituting 20% or less of total stock ownership are subject to certain conditions.

Stock Ownership Guidelines.The Board adopted stock ownership guidelines to closely align the interests of our executive officersexecutives with those of our long-term stockholders. Under the guidelines, the Chief Executive OfficerCEO is expected to maintain a minimum investment on our common stock of five times his annual salary and other senior executive officersexecutives are expected to maintain a minimum investment on our common stock of the lesser of 5,000 shares or one times their respective annual salaries. All of our senior executive officersexecutives substantially exceed the ownership requirements under our stock ownership guidelines. These ownership levels are to be achieved no later than four years after the election as an executive officer, except that prior to such time the officer is expected to retain a certain portion of stock issued upon exercise

of stock options or vesting of restricted stock awards until the minimum ownership levels are attained. For more information, including recent updates to these guidelines, see "Corporate GovernanceProposal 1 - Director Compensation - Director and Executive Officer Stock Ownership Guidelines."

Clawback Policies.In 2015, the Compensation Committee approved a compensation recovery policy that allows the Company to recapture cash and equity performance-based compensation from executives if the amount of the award was based upon achieving certain financial results that were later restated due to the participant'sparticipant’s misconduct. In addition, all equity awarded to employees since 2007 contain a provision under which employees may be required to forfeit equity awards or profit from equity awards if they engage in certain conduct, including competing against the Company, disclosing confidential information, or soliciting its employees or customers.

The awards are reported based on the fair value as of the grant date determined pursuant to ASC Topic 718.

The option exercise price has not been deducted from the amounts indicated above and we disregard an estimate of forfeitures. Regardless of the value placed on an equity award on the grant date, the actual value of the equity award will depend on the market value of our common stock at such date in the future when the RSU vests or the stock option is exercised, and the performance of our common stock in relation to the S&P Composite 1500 Electronic Equipment, Instrument and Components stock index on the measurement date with respect to the PSU. For informational purposes, if the maximum level of performance were achieved for the PSUs, the values as limited by the 600% value cap are $5,403,197, $2,611,169, $2,274,664 and $2,253,796 for Dr. Scherbakov, Messrs.

Amounts shown include the payouts under the AIP for 2016 financial performance at the three goals plus individual performance at maximum for each. The performance goals used in determining AIP payments are discussed in the Compensation Discussion and Analysis above. Actual amounts paid for 2016 performance are shown in the "Non-Equity Incentive Plan Compensation" column in the Summary Compensation Table above.
(2)
For a description of the performance-based stock units, see Compensation Discussion and Analysis-Equity-Based Incentives Granted in 2016.
(3)The amounts listed reflect restricted stock units and stock options granted under our 2006 Incentive Compensation Plan and are described in the Outstanding Equity Awards Table below.
(4)The awards are reported based on the fair value of such award as of the grant date determined pursuant to ASC Topic 718. The assumptions that we used with respect to the valuation of equity awards are set forth in Note 2 to our Consolidated Financial Statements in our Annual Report on Form 10-K filed with the SEC on February 27, 2017. The option exercise price has not been deducted from the amounts indicated above and we disregard an estimate of forfeitures. Regardless of the value placed on an equity award on the grant date, the actual value of the equity award will depend on the market value of our common stock at such date in the future when the restricted stock unit vests or the stock option is exercised, and the performance of our common stock in relation to the Russell 3000 on the measurement date with respect to the award. For informational purposes, if the maximum level of performance was achieved for the performance-based stock units, the values, calculated by multiplying the closing stock price on the grant date by the number of shares issuable upon achievement of the maximum level of performance, are $749,406, $749,406, $631,152 and $614,766 for Mr. Mammen, Drs. Scherbakov and Ovtchinnikov, and Mr. Ness, respectively.

If the employment period of any of the Named Executive OfficersNEOs terminates and the Company does not offer such officerNEO continued employment in the same or a substantially similar position or in a higher position than the officer'sNEO's position at the end of the employment period and at a compensation level that is the same or substantially similar to the compensation level in effect at the end of the employment period, then such officerNEO may resign from employment and would receive continuation of salary and health benefits for twelve months, except for the Chief Executive OfficerCEO who would receive the same for twenty-four months, plus a portion of the annualpro-rated bonus that the executive would have received had he remained employed through the end of the applicable bonus period, based on actual performance, including the individual performance element (the portion based upon the percentage offor the year that he was employed by the Company).

Executive Compensation Tables

The following table provides information regarding compensation and benefits that would be payable to our Named Executive OfficersNEOs as of December 31, 2016,2019, upon an Involuntary Termination absent a change in control and preceded by a change in control and upon terminations in other circumstances. The incentive plan severance was calculated using the actual amount awarded under the 20162019 AIP. There can be no assurance that the event triggering payments would produce the same or similar results as those described below if such event occurs on any other date or at any other price, or if any other assumption used to estimate the potential payments and benefits is incorrect. Any actual payments and benefits may be different due to a number of factors that affect the nature and amount of any potential payments or benefits.

56 NOTICE OF 2020 ANNUAL MEETING AND PROXY STATEMENT


Executive Compensation Tables


CEO Pay Ratio
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are providing the following information on the relationship of the annual total compensation of our employees and the annual total compensation of Dr. Valentin P. Gapontsev, our CEO.
Determining our Median Employee: As permitted by SEC rules, because there has been no change in our employee population or employee compensation arrangements that we believe would significantly impact the pay ratio disclosure, the Company determined to use the same median employee in our pay ratio calculation as was used in the proxy statement for the 2018 and 2019 annual meeting of stockholders. However, the median employee used in the proxy statement for the 2018 and 2019 annual meeting of stockholders terminated employment with the Company in 2019. Therefore, as permitted under SEC rules, the Company identified an alternate median employee with comparable pay as the median employee in 2018 for this Proxy Statement.
Calculating the Pay Ratio: As required by the SEC rules, we calculated our median employee’s total annual compensation in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K (which is the calculation method for reporting CEO compensation in the Summary Compensation Table).
The total compensation of our median employee was $31,205. Our CEO’s total compensation as reported in the Summary Compensation Table for 2019 was $1,251,984. Therefore, our CEO to median employee pay ratio in 2019 was approximately 40.1:1.
The pay ratio included in this information is a reasonable estimate calculated in a manner consistent with rules promulgated by the SEC. This information is being provided solely for compliance purposes. The Compensation Committee does not consider this ratio when evaluating compensation arrangements.

EQUITY COMPENSATION PLANS
Equity Plans
Our 2006 Incentive Compensation Plan (the “2006 Plan”) enables the Company to make stock-based and non-stock awards to its eligible employees, non-employee directors and independent contractors. The 2006 Plan provides for the grant of: incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, stock units, performance shares, performance units, cash awards, and any combination of the foregoing. The purpose of the 2006 Plan is to motivate employees, non-employee directors and independent contractors by providing an opportunity to acquire cash or equity incentive awards, and to provide a means through which the Company, its affiliates and group companies may attract the highest-quality individuals to enter employment or engagement with the Company or its affiliates and to align the interests of such individuals with the Company's stockholders.
The 2006 Plan was approved by our stockholders in 2006 and amendments were approved by stockholders in 2011 and again in 2015. The 2006 Plan terminates in June 2025. The maximum number of shares authorized for issuance under the 2006 Plan is 10,279,192 shares, which includes the 10,000,000 shares approved at the 2011 annual meeting of stockholders, 84,273 shares previously authorized and approved for issuance but not awarded under the IPG Photonics 2000 Incentive Compensation Plan (the “2006 Plan”) and rolled into the 2006 Plan and 194,919 shares previously authorized and approved for issuance but not awarded under the IPG Photonics Corporation Non-Employee Directors Stock Plan which were rolled into the 2006 Plan.
Generally, any shares underlying an award under the 2006 Plan that expire without being exercised, or are forfeited, canceled or otherwise terminated without a distribution to a participant of shares, cash, or other benefit in lieu of shares will again be available for issuance under the 2006 Plan. Notwithstanding the foregoing, the following shares may not be recycled into the 2006 Plan and again become available for issuance: (i) shares tendered to pay the exercise price of stock options and stock appreciation rights (including through "net exercise"), (ii) the total number of shares granted pursuant to stock-settled stock appreciation rights, (iii) any shares withheld by the Company to satisfy tax obligations with respect to any awards, and (iv) shares repurchased on the open market with the proceeds of the stock option exercise price.
The 2006 Plan provides for the following award limitations:
The maximum aggregate number of shares underlying all stock options, stock appreciation rights and any other awards that are intended to qualify as performance-based compensation under Internal Revenue Code Section 162(m) and are measured in shares (whether payable in shares, cash or a combination of both) that may be granted to any single participant (other than a non-employee director) in any single calendar year is 1,000,000 shares, as adjusted for any Company recapitalization, reorganization, stock dividend or similar event.

The Company may not grant cash awards intended to qualify as performance-based compensation under Internal Revenue Code Section 162(m) with respect to more than $4,000,000 to any single participant in any single calendar year.

In determining a cash award payout to a single "covered employees" (as defined in Internal Revenue Code Section 162(m)) in a single year through the use of an incentive pool, the percentage of the incentive pool allocated to such covered employee may not exceed 30% of the total incentive pool. In addition, the aggregate payments to all incentive pool participants may not exceed 100% of the incentive pool.

The maximum aggregate number of shares underlying all awards measured in shares (whether payable in shares, cash or a combination of both) that may be granted to any single participant who is a non-employee director in any period beginning on an annual stockholder meeting date and ending on the day immediately preceding the following annual stockholder meeting date is 50,000 shares, as adjusted for any Company recapitalization, reorganization, stock dividend or similar event.

The Company may not grant total cash awards (inclusive of annual retainer amounts under the director compensation plan) more than $250,000 to any single non-employee director in any single calendar year.

No more than 833,333 shares may be cumulatively available for awards of incentive stock options under the 2006 Plan and maximum aggregate number of shares underlying awards that may be granted in any calendar year to any participant as incentive stock options is 133,333.

Each share of restricted stock, stock unit, performance share, performance unit or other award under the 2006 Plan with value denominated in full shares shall equate to 1.60 shares of common stock for purposes of determining any individual or aggregate award limitations under the 2006 Plan and for purposes of calculating the aggregate number of shares available for awards under the 2006 Plan. If any such awards again become available for issuance under the 2006 Plan as described above, the number of shares added back to the 2006 Plan will follow the same 1.60 per share ratio.
Stock options, stock appreciation rights, restricted stock, stock units, performance shares, performance units, and other equity-based awards under the 2006 Plan are subject to a minimum required vesting period of one year, except that up to 5% of the shares reserved for issuance under the 2006 Plan may be granted to participants without regard to any minimum vesting periods. The 2006 Plan prohibits the granting of dividend equivalent rights with respect to stock options and stock appreciation rights. Also, the 2006 Plan provides a limited exception to double-trigger vesting by causing awards granted under the 2006 Plan to immediately vest upon a change in control only if the successor entity does not agree to assume outstanding awards or replace outstanding awards with economically equivalent awards. If the If the awards are assumed or replaced with economically equivalent awards, then such awards are treated the same as under the Current Plan-the vesting of awards will only be accelerated if, within two years following a change in control, the participant's employment is terminated by the Company without "Cause" or by the participant for "Good Reason" (each term as defined in the 2006 Plan).
In the event of a change in control (as defined in the 2006 Plan) and a participant's subsequent termination within 24 months of the change in control either (i) by the Company other than for "Cause" or (ii) by the participant for "Good Reason," unless the Compensation Committee expressly provides otherwise in an applicable award agreement, any outstanding awards held by the participant will immediately become vested and exercisable in full. "Cause" and "Good Reason" have the meanings set forth in any applicable employment, consulting, severance or other written agreement between the Company and the participant or, if none, any award agreement or, if none, the 2006 Plan. The Compensation Committee has the discretion to terminate all or a portion of any outstanding awards upon a change in control, after giving notice to each affected participant. Each affected participant would receive an amount equal to the value of such award on the date of the change in control or, with respect to each share of stock subject to a stock option or stock appreciation right, an amount equal to the excess of the fair market value of the shares of stock immediately prior to the occurrence of the change in control over the exercise price per share of such stock option or stock appreciation right. Such amounts would be payable in cash, other property or a combination thereof, in the Committee's discretion. Awards granted to non-employee directors vest upon a change in control.
The 2006 Plan is administered by the Compensation Committee and has delegated to our Chief Executive Officer the authority to grant up to a specific number of equity awards to current or prospective employees (other than those individuals subject to Section 16(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") at the time of grant) in the Chief Executive Officer's discretion.
Employee Stock Purchase Plan
We maintain an employee stock purchase plan, which is intended to be qualified under Section 423 of the Code. Each of our U.S. employees and a limited group of our German employees who customarily work more than 20 hours per week and more than five months in any calendar year is eligible to participate in this plan after completing six months of service. To participate in the plan, an employee may designate prior to the commencement of a six-month offering period the amount of payroll deductions to be made from his or her paycheck for the purchase of shares of our common stock under the plan, which amount may not exceed 10% of his compensation. On each purchase date, shares of our stock are purchased automatically for each participant with the amounts withheld from his or her payroll deductions at a price equal to 85% of the lesser of the fair market value of the shares on the purchase date or the fair market value of the shares on the first day of the offering period. An employee may not participate in an offering period if, immediately after the purchase of shares, the employee would own shares or hold options to purchase shares of our stock possessing 5% or more of the total combined voting power or value of all classes of our stock. The employee stock purchase plan includes a "Non-Code Section 423 Component" for the employees of subsidiaries outside the United States.

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION
In accordance with the requirements of Section 14A of the Exchange Act and the related rules of the SEC, our stockholders have the opportunity to cast an advisory vote to approve the compensation of our Named Executive Officers as disclosed pursuant to the SEC's compensation disclosure rules, including the Compensation Discussion and Analysis, the compensation tables and the narrative disclosures that accompany the tables (a "say-on-pay proposal").
Our compensation program is designed to be simple, effective and link pay to performance. It reflects the size, scope and success of IPG's business as well as the responsibilities of our Named Executive Officers. We believe our compensation program strikes the appropriate balance between utilizing responsible, measured pay practices and effectively incentivizing our executives to dedicate themselves fully to value creation for our stockholders. This balance is evidenced by IPG Photonics' best pay practices:
What We DoWhat We Don't Do
Align our Officer Pay with Performance:
Compensation is tied to Company performance and stockholder returns, including performance stock units which are earned based upon IPG's total stockholder return.
No Retirement Benefits:
We have no supplemental executive retirement plans (SERPs) or defined benefit pension plans.
Balance Annual and Long-Term Incentives:
Incentive programs provide an appropriate balance of annual and long-term incentives and include multiple measures of performance.
No Tax Gross-Ups: We do not provide tax gross reimbursements for change in control payments or executive perquisites, which are limited.
Use Long-Term Incentives to Link Executive Pay to Company Performance: 52% of NEO (other than the CEO) pay consists of long-term incentives linked to increasing our stock price.
Hedging of Company Stock is Prohibited. We have Limits on Pledging
Cap Incentive Awards:  Annual incentive plan awards and certain long-term incentives plan awards are capped.
No Severance For "Cause" Terminations
Maximize Stockholder Value While Mitigating Risk: Annual option and restricted stock unit equity awards vest over four years. These incentives drive growth over the long-term, discouraging short-term risk taking.
No Single-Trigger Change in Control Provisions
Have Stringent Stock Ownership Requirements:
NEOs substantially exceed our ownership guidelines.
No Stock Option Repricing without Stockholder Approval

Impose Clawbacks on Executive Compensation: In 2015, weadopted a compensation recovery policy.


As an advisory vote, the results of this vote will not be binding upon the Board or the Company. However, the Compensation Committee and the Board values the opinions expressed by our stockholders on this proposal and will consider the outcome of the vote when making future decisions on the compensation of our Named Executive Officers.
Before you vote, we encourage you to review the Compensation Discussion and Analysis on pages 30-40 of this proxy statement for additional details on our executive compensation.

OUR BOARD OF DIRECTOR RECOMMENDS
A VOTE "FOR" APPROVAL OF EXECUTIVE COMPENSATION

PROPOSAL 3: VOTE ON THE FREQUENCY OF ADVISORY VOTES ON EXECUTIVE COMPENSATION
In accordance with the requirements of Section 14A of the Exchange Act and the related rules of the SEC, our stockholders have the opportunity to cast an advisory vote to approve the compensation of our named executive officers as described in Proposal 2. This Proposal 3 affords stockholders the opportunity to cast an advisory vote on how often we should include a similar say-on-pay proposal in our proxy materials for future stockholder meetings or any special meetings for which we include executive compensation information in the proxy statement for that meeting (a "say-on-pay frequency proposal"). Under this Proposal 3, stockholders may vote to have the say-on-pay vote every one year, two years or three years. In addition, stockholders may abstain from voting.
The law requires the Company to hold an advisory vote on say-on-pay frequency at least once every six years. Our stockholders voted on a similar proposal in 2011 with the three year say-on-pay frequency receiving a greater number of votes than the one year or two year alternatives. We continue to believe that the say-on-pay vote should be conducted every three years and that this frequency is appropriate for the following reasons:
our compensation programs do not change significantly from year to year and we seek to be consistent,
a longer frequency is consistent with long-term compensation objectives (we do not want to encourage a short-term view in our compensation practices),
our compensation programs are designed to reward and incentivize long-term performance and a triennial vote closely corresponds with the three- to four-year vesting of our long-term incentive awards,
our directors, including members of the Compensation Committee, are elected annually for terms of one year, allowing stockholders to express their views through the annual election process and
our stockholders overwhelmingly approved our executive compensation in our say-on-pay advisory votes, with 99% of the votes cast in favor our executive compensation in both 2014 and 2011, signaling strong stockholder approval of alignment of our executive compensation with performance.
We encourage our stockholders to evaluate our executive compensation programs over a multi-year horizon. A triennial say-on-pay vote reflects the appropriate time frame for the Compensation Committee to evaluate the results of the most recent say-on-pay vote, to discuss the implications of that vote with stockholders to the extent needed, to develop and implement any adjustments to our executive compensation programs that may be appropriate in light of a past say-on-pay vote, and for stockholders to observe and evaluate the Compensation Committee’s actions in context. Some institutional stockholders believe that triennial say-on-pay votes support a longer-term focus on Company performance.
Because the say-on-pay vote occurs after we have already implemented our executive compensation programs for the current year, and because the different elements of compensation are designed to operate in an integrated manner and to complement one another, we expect that in certain cases it may not be appropriate or feasible to fully address and respond to any one year’s say-on-pay vote by the time of the following year’s annual meeting of stockholders.
We are aware that some stockholders believe that annual say-on-pay votes will enhance or reinforce accountability. However, we will continue to be engaged with our stockholders. Thus, we view the say-on-pay vote as an additional but not exclusive opportunity for our stockholders to communicate with us regarding their views on the Company’s executive compensation programs.

51





 In addition, because our executive compensation programs have typically not changed materially from year to year and are designed to operate over the long term and to enhance long-term performance, we are concerned that an annual say-on-pay vote could lead to a near-term perspective that is inappropriate for evaluating our executive compensation programs.

Finally, although we believe that holding a say-on-pay vote every three years will reflect the right balance of considerations in the normal course, we will periodically reassess that view and can provide for a say-on-pay vote on executive compensation on a more frequent basis if changes in our compensation programs or other circumstances indicate that such a vote would be appropriate.

OUR BOARD OF DIRECTORS RECOMMENDS
A VOTE TO HOLD SAY-ON-PAY VOTES EVERY THREE YEARS
AS OPPOSED TO EVERY ONE YEAR OR TWO YEARS

AUDIT COMMITTEE REPORT
The primary role of the Audit Committee is to assist the Board of Directors in fulfilling its oversight responsibilities by reviewing the financial information proposed to be provided to stockholders and others, the adequacy of the system of internal control over financial reporting and disclosure controls and procedures established by management and the Board, and the audit process and the independent registered public accounting firm's qualifications, independence and performance.
Management has primary responsibility for the financial statements and is responsible for establishing and maintaining the Company's system of internal controls and for preparation of the Company's financial statements. The Company's independent registered public accounting firm, Deloitte & Touche LLP, is responsible for performing an integrated audit of the Company's consolidated financial statements and the effectiveness of internal controls over financial reporting in accordance with standards of the Public Company Accounting Oversight Board (United States) (PCAOB) and issuing an opinion on the financial statements and the effectiveness of internal controls over financial reporting. The Audit Committee also employs an international auditing firm to conduct internal audits throughout the Company of various financial, operational and information technology areas as selected each year by the Audit Committee. The Audit Committee periodically met and held separate discussions with the internal auditors and the Company's independent registered public accounting firm, with and without management present, to review the adequacy of the Company's internal controls, financial reporting practices and audit process.
The Audit Committee has reviewed and discussed the Company's audited consolidated financial statements for the year ended December 31, 2016 with management and the independent registered public accounting firm. As part of this review, the Audit Committee discussed with Deloitte & Touche LLP the required communications described in Auditing Standard No. 16, Communication with Audit Committees, and those matters required to be reviewed pursuant to Rule 2-07 of Regulation S-X as well as the results of their audit of the effectiveness of internal controls over financial reporting.
The Audit Committee has received from Deloitte & Touche LLP a written statement describing all relationships between that firm and the Company that might bear on their independence, consistent with PCAOB Ethics and Independence Rule 3526, Communications with Audit Committees Concerning Independence. The Audit Committee has discussed the written statement with the independent registered public accounting firm and has considered whether its provision of any other non-audit services to the Company is compatible with maintaining the auditors' independence.
Based on the above-mentioned reviews and discussions, the Audit Committee recommended to the Board of Directors that the Company's audited consolidated financial statements be included in its Annual Report on Form 10-K for the year ended December 31, 2016, as filed with the SEC.
The information in this Audit Committee Report shall not be considered "soliciting material" or "filed" with the SEC, nor shall this information be incorporated by reference into any previous or future filings under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except to the extent that the Company incorporated it by specific reference.

PROPOSAL 4: RATIFY INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
Deloitte & Touche LLP currently serves as our independent registered public accounting firm and audited our consolidated financial statements for the year ended December 31, 2016.2019. Our Audit Committee has appointed Deloitte & Touche LLP to serve as our independent registered public accounting firm for 2017,2020, and to conduct an integrated audit of our consolidated financial statements for the year ending December 31, 20172020 and of our internal control over financial reporting as of December 31, 2017.2020. Deloitte & Touche LLP has served as the Company’s auditor since 1999. A representative of Deloitte & Touche LLP will attend the Annual Meeting where he or she will have the opportunity to make a statement, if he or she desires, and will be available to respond to appropriate stockholder questions.
The Audit Committee is solely responsible for the appointment, retention, termination and oversight of the work of our independent registered public accounting firm, including the approval of all engagement fees, terms, and the annual audit plan. In determining whether to reappoint Deloitte & Touche LLP as the Company'sCompany’s independent external auditor, the Audit Committee took into consideration several factors, including an assessment of the professional qualifications and past performance of the lead audit partner and the Deloitte & Touche LLP team, the quality and level of transparency of the Audit Committee'sCommittee’s relationship and communications with Deloitte & Touche LLP. The Audit Committee considered, among other things, the knowledge and skills of Deloitte & Touche LLP'sLLP’s auditing experts that would be providing services to the Company, international scope and knowledge of the Company and its operations. After its assessment, the Audit Committee concluded that the best course of action was to reappoint Deloitte & Touche LLP as the Company'sCompany’s independent external auditor for 2017.2020. Lead and concurring audit partners are subject to rotation requirements that limit the number of consecutive years an individual partner may provide services. The maximum number of consecutive years of service in that capacity is five years and 2019 will be2024 is a year of lead audit partner rotation. The Audit Committee was directly involved in the selection process of the current and prior lead audit partners. In 2014, the process for rotation of the Company's lead audit partner involvedinvolves an inquiry into the backgrounds and experiences of several potential lead partners, a narrowing of the list to one or more, a meeting between the candidate or candidates for the role with the Chair of the Audit Committee, and the successor candidate, as well as meetings with management. This is accompanied by several discussions with and a final approval by the entire Audit Committee. The Company and Audit Committee followed this process in the 2019 selection of the lead audit partner from Deloitte & Touche LLP.

Proposal
4
Stockholder Proposal to Prepare a Report on Management Team Diversity
The Company has received notice of the intention of a stockholder to present a proposal for voting at the Annual Meeting. The text of the stockholder proposal and supporting statement appear below exactly as received by the Company. All statements contained in the stockholder proposal and supporting statement are the sole responsibility of the proponent of the stockholder proposal. The Company will provide the name, address and stockholdings (to the Company’s knowledge) of the proponent upon request made to Office of the Secretary, IPG Photonics Corporation, 50 Old Webster Road, Oxford, Massachusetts 01540 or by calling (508) 373-1100.
If the proponents of this proposal, or representatives who are qualified under state law, are present at our directorsannual meeting and submit the proposal for a vote, then the proposal will be voted upon.
Beginning of Stockholder Proposal and Statement of Support:
Stockholder Proposal regarding a Report on Diversity in Executive Leadership
WHEREAS:
We believe that diversity, inclusive of gender and race, are critical attributes of a well-functioning executive team and necessary to meaningfully drive diversity throughout an organization.
Currently, IPG Photonics management team has no woman and an undeterminable number of people of color.
The business case for workforce diversity is compelling. McKinsey & Company, found in 2015, and in a larger 2017 study that highly diverse executive teams had higher returns on equity and earnings performance than those with low diversity. ISS Analytics examined companies where the CEO had a tenure of at least three years and found companies that combined gender diversity in the boardroom and the C-Suite showed, overall, the best results in terms of risk-adjusted quality of performance. (ISS Analytics/Governance Insights/October, 2018)
Yet, the number of women and people of color in leadership roles remains low. Nine percent of top executive roles in the Russell 3000 are held by women. Among S&P500 companies women comprise 44.7 percent of all employees yet just 26.5 percent of executives, senior officials and managers. Women of color face a wider gap.
Companies across industries are setting goals to address this significant issue. Intel has been tracking diversity data since 2014 and ties diversity goals to incentive compensation. In 2018, two years ahead of schedule, Intel achieved full representation of underrepresented minorities and women in its U.S. workforce. Symantec set a goal to increase the percentage of women in leadership (Director-level and above) to thirty percent by 2020. Citigroup, in 2018, announced plans to reverse “falling diversity” by setting public quantitative goals and holding senior leaders accountable for meeting them.
IPG Photonics has strengthened diversity on its board of directors. It is time to extend focus and accountability to building diversity in its leadership ranks.
To address the lack of diversity in senior roles we believe the Board must set clear policies to attract, retain and promote women and people of color, including reporting on gender pay equity, establishing sponsorship programs, and family support programs.
Further, we believe that linking diversity performance metrics to senior executive compensation packages can sharpen management’s ability to manage human capital risks, increase accountability and successfully reach inclusion and diversity goals.
RESOLVED: Shareholders request that the Board of Directors prepare a report (at a reasonable cost, in a reasonable time, and omitting confidential information) providing its assessment of the current state of its management team diversity and if and how it plans to make the Company’s management team more diverse in terms of race, ethnicity, and gender.
Supporting Statement: A report adequate for investors to assess IPG Photonic’s strategy and performance could include disclosures such as use of “Rooney Rule” practices when interviewing for open positions, and hiring and promotion rates of women and people of color across employment.
End of Stockholder Proposal and Statement of Support

Proposal 4 Stockholder Proposal

BOARD OF DIRECTORS STATEMENT IN OPPOSITION
The Board of Directors carefully considered the stockholder proposal and does not believe that the proposal is in the best interests of the Company or its stockholders for the reasons below.
The Company and its leadership have a long-standing commitment to diversity, inclusion and advancement. We believe that we are made better and stronger by having a diverse and inclusive workforce shaping our business choices, and we are culturally enriched by having the unique perspectives of people of all backgrounds.
The Board acknowledges the benefits of diversity throughout the Company, including its management team. Our Company has been fortunate to not experience impactful senior management turnover. Despite this, we have made strides to increase diversity in manager positions below our upper management, building internal resources for potential future executive openings. For example, women and minorities comprise over 40% of our global management below the executive level. In addition, we have increased diversity exceeding our recent affirmative action plans.
Even in the midst of unprecedented trade uncertainties and competitive challenges facing the Company in 2018 and 2019, we have taken a number of actions to promote our diversity and inclusion initiatives, including the following:
Our executive team has made improvements in making our hiring and promotion of women and minorities a priority and correspondingly the Company has attained improvement in its diversity.
The Company has been subject to two audits of the Office of Federal Contract Compliance Programs (A federal government office monitoring employment discrimination at government contractors), without any adverse findings.
We recruit and develop candidates for available leadership and other positions at the Company identifying persons from diverse backgrounds and with a variety of life experiences, including posting on national and local diversity job boards as well as partnerships with organizations, community groups and colleges that focus on the needs of minority candidates.
We annually send letters to our recruiters informing them of our commitment to recruit and draw from diverse pool of applicants including women and minority candidates.
We actively recruit at universities having higher than average populations of women and minorities in STEM (science, technology, engineering and math) related programs. Also, we support our female engineering employees in attending conferences of their peers and sponsor a female development program at a local college.
We maintain a “Diversity & Inclusion” microsite on our website, available under the “Our People and Communities” link on the “Our Company” page of our website, which provides potential candidates with insight into our diversity and inclusiveness initiatives as well as a view into our diverse and inclusive culture and workforce.
We focus on identifying persons from diverse backgrounds, skills and with a variety of life experiences as candidates for our Board as promoted by our director membership guidelines.
We support our diverse workforce and our commitment to an equal opportunity for all employees through a variety of methods, including a confidential ethics hotline, which promotes reporting of concerns regarding conduct that violates our Code of Business Conduct.
In summary, the Company remains fully committed to our ongoing efforts to promote diversity and foster an inclusive environment for all employees throughout the Company, but we do not believe that this stockholder proposal would advance those goals, nor do we believe that the reporting obligations expected in the stockholder proposal would provide a demonstrated benefit to our stockholders.
The Board of Directors unanimously recommends that you vote AGAINSTthis proposal.

WHERE:
IPG Photonics Corporation
50 Old Webster Road
Oxford, Massachusetts 01540
What is the Impact of COVID-19 on the Annual Meeting?
Circumstances are changing rapidly. We currently intend to file reportshold the Annual Meeting in person. We are monitoring coronavirus (COVID-19) developments and the related recommendations and protocols issued by public health authorities and federal, state, and local governments. If we determine that alternative Annual Meeting arrangements are advisable or required, which may include switching to a virtual meeting format, or changing the time, date or location of ownershipthe Annual Meeting, then we will announce our decision via press release and the filing of and transactions in, our securitiesadditional proxy materials with the SEC. Please monitor our investor website at investor.ipgphotonics.com in advance of the Annual Meeting date if you are planning to attend in person. Please note that: (i) we will not be serving food and drink as we had in past years and (ii) we do not intend to have a presentation concerning the results from 2019.
What is the Purpose of These Materials?
The Board is soliciting proxies from our stockholders in connection with our annual meeting of stockholders to be held on Thursday, May 28, 2020 and any and all adjournments thereof. This Proxy Statement and our Annual Report are first being made available to stockholders of record on or about April 9, 2020 at investor.ipgphotonics.com. Information on the website does not constitute part of this Proxy Statement. Unless otherwise noted, the information in this Proxy Statement covers our 2019 fiscal year, which ran from January 1, 2019 through December 31, 2019.
What Matters Am I Being Asked to Vote On at the Meeting and What Vote is Required to Approve Each Matter?
You are being asked to vote on four proposals.
Proposal 1 requests the election of directors executive officers and 10% stockholders are also required to furnish us with copiesnamed in this Proxy Statement. Our bylaws require that, in uncontested elections, each director be elected by the majority of all Section 16(a) forms that they file. Based solely on its review of such forms received by it and the written representations of its Reporting Persons, the Company has determined that no such persons known to it were delinquentvotes cast with respect to their reporting obligationssuch director. This means that the number of shares voted “for” a director nominee must exceed the number of votes cast “against” that nominee in order for that nominee to be elected. Only votes “for” or “against” are counted as set forthvotes cast with respect to a director. Abstentions and broker non-votes (as defined below) will have no effect on Proposal 1. To be elected in Section 16(a)a “contested election” of directors, which our bylaws define as an election in which the number of nominees for director is greater than the number of directors to be elected, as determined as of the tenth day preceding the date the Company first mails its notice of meeting to stockholders, a director nominee must receive a plurality of the votes cast. The election of directors at the Annual Meeting is an uncontested election.
Proposal 2 requests the approval of our executive compensation. Proposal 2 is an advisory vote, which means that it is not binding on the Company.                    
Proposal 3 requests the ratification of the appointment of our independent registered public accounting firm for 2020.
Proposal 4 is a stockholder proposal, if properly presented at the meeting.
The affirmative vote of the holders of a majority of the outstanding shares which are present at the meeting in person or by proxy, and entitled to vote thereon, is required for approval of Proposals 2, 3 and 4. Abstentions have the same effect as voting against Proposals 2, 3 and 4. Broker non-votes have no effect on Proposals 2 and 4. Because Proposal 3 is considered a “routine” matter, broker non-votes are not expected to occur with respect to this Proposal.
No business can be conducted at the Annual Meeting unless a majority of all outstanding shares entitled to vote are either present in person or represented by proxy at the meeting. As far as we know, the only matters to be brought before the Annual Meeting are those referred to in this Proxy Statement. If any additional matters are presented at the Annual Meeting, the persons named as proxies may vote your shares in their discretion.

Questions and Answers About the Meeting and Voting

What Happens if a Director Nominee Fails to Receive a Majority Vote in an Uncontested Election at the Annual Meeting?
If a nominee who currently is serving as a director does not receive the affirmative vote of at least a majority of the votes cast in an uncontested election, Delaware law provides that the director would continue to serve on the Board as a “holdover director.” However, under our bylaws, each incumbent director is required to submit a letter of resignation as a condition of becoming a nominee of the Board, with the resignation contingent upon not receiving a majority of the votes cast in an uncontested election and acceptance of the resignation by the Board. In such event, the NCGC (or another committee designated by the Board) would make a recommendation to the Board as to whether to accept or reject the tendered resignation, or whether other action should be taken. The Board would act on the tendered resignation, taking into account the committee’s recommendation, and would publicly disclose its decision regarding the resignation within 90 days after the results of the election are certified. If the resignation is not accepted, the director would continue to serve until the next annual meeting of stockholders and until the director’s successor is elected and qualified.
Who Is Entitled to Vote at the Annual Meeting?
You are entitled to vote at the Annual Meeting if you owned shares of IPG (directly or in “street name,” as defined below) as of the close of business on April 1, 2020, the record date for the Annual Meeting. On that date, 53,142,181 shares of our common stock were outstanding and entitled to vote and no shares of our preferred stock were outstanding. Each share of our common stock is entitled to one vote with respect to each matter on which it is entitled to vote. There is no cumulative voting with respect to any proposal.
What Do I Need to Do If I Plan to Attend the Annual Meeting in Person?
If you plan to attend the Annual Meeting in person, you must provide proof of your ownership of our common stock and a form of personal identification, such as a driver’s license, for admission to the Annual Meeting. If you are a stockholder of record, the top half of your proxy card is your admission ticket and will serve as proof of ownership. If you hold your shares in street name, a recent brokerage statement or a letter from your bank or broker are examples of proof of ownership. If you hold your shares in street name and you also wish to be able to vote at the Annual Meeting, you must obtain a proxy, executed in your favor, from your bank or broker.
What Is the Difference Between Holding Shares Directly as a Stockholder of Record and Holding Shares in “Street Name” at a Bank or Broker?
Most of our stockholders hold their shares directly through a broker, bank or other nominee rather than directly in their own name. As summarized below, there are differences between shares held of record and those held in “street name.”
Stockholder of Record: If your shares are registered directly in your name with our transfer agent, Computershare, N.A., you are considered the stockholder of record with respect to those shares, and the Proxy Statement and Annual Report were sent directly to you. As the stockholder of record, you have the right to vote your shares as described herein.
“Street Name” Stockholder: If your shares are held by a bank, broker or other nominee on your behalf, you are considered the beneficial owner of shares held in “street name,” and the Proxy Statement and Annual Report were forwarded to you by your bank, broker or other nominee who is considered the stockholder of record with respect to those shares. Your bank, broker or other nominee sent to you, as the beneficial owner, a document describing the procedure for voting your shares. You should follow the instructions provided by your bank, broker or other nominee to vote your shares. You are also invited to attend the Annual Meeting. However, if you wish to be able to vote at the meeting, you must obtain a proxy card, executed in your favor, from your bank, broker or other nominee.
What Does it Mean to Give a Proxy?
Your properly completed proxy/voting instruction card will appoint Valentin P. Gapontsev and Angelo P. Lopresti as proxy holders or your representatives to vote your shares in the manner directed therein by you. Dr. Gapontsev is our Chairman of the Board and CEO. Mr. Lopresti is our Senior Vice President, General Counsel and Secretary. Your proxy permits you to direct the proxy holders to vote “For,” “Against,” or “Abstain” for each of the proposals included in this Proxy Statement.
All of your shares entitled to vote and represented by a properly completed proxy or voting instruction received prior to the Annual Meeting and not revoked will be voted at the meeting in accordance with your instruction.

Questions and Answers About the Meeting and Voting

What Happens If I Sign, Date and Return My Proxy But Do Not Specify How I Want My Shares Voted on One of the Proposals?
Stockholder of Record: Your proxy will be counted as a vote “For” all of the nominees for director (Proposal 1), “For” the advisory approval of our executive compensation, “For” the ratification of the appointment of our independent registered accounting firm (Proposal 3) and "Against" the stockholder proposal (Proposal 4).
“Street Name” Stockholder: Your bank, broker or nominee may vote your shares only on those proposals on which it has discretion to vote. Under the rules of Nasdaq, your bank, broker or nominee does not have discretion to vote your shares on non-routine matters, such as the election of directors (Proposal 1), advisory approval of our executive compensation (Proposal 2) and the stockholder proposal (Proposal 4). This is called a “broker non-vote.” However, your bank, broker or nominee does have discretion to vote your shares on routine matters such as the vote to ratify the appointment of our independent registered public accounting firm (Proposal 3). Accordingly, if you do not give your bank, broker or nominee specific instructions with respect to Proposal 3, your shares will be voted in such entity’s discretion (but only with respect to Proposal 3). We urge you to promptly provide your bank, broker or nominee with appropriate voting instructions so that all of your shares may be voted at the Annual Meeting.
Can I Change My Vote Before the Annual Meeting?
You can change your vote at any time before your proxy is exercised by delivering a properly executed, later-dated proxy (including an Internet or telephone vote), by revoking your proxy by written notice to the Secretary of IPG, or by voting in person at the Annual Meeting. If you choose to revoke your proxy by attending the Annual Meeting, you must vote your shares for revocation to be effective. The method by which you vote by a proxy will in no way limit your right to vote at the meeting if you decide to attend in person.
If your shares are held in street name, please refer to the information forwarded by your bank, broker or nominee for procedures on changing your voting instructions.
Is the Proxy Statement Available on the Internet?
Yes. We are delivering this Proxy Statement and the Annual Report pursuant to the Securities and Exchange Act.Commission rules that allow companies to furnish proxy materials to their stockholders over the Internet. On or about April 9, 2020, we will mail to our stockholders a notice (the “Notice”) containing instruction on how to access this Proxy Statement and the Annual Report and to vote via the Internet or by telephone. Stockholders can view these documents on the Internet by accessing the website at investor.ipgphotonics.com.
2018What Does it Mean If I Receive More Than One Notice of Internet Availability of Proxy Materials?
You may receive more than one Notice, more than one e-mail or multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you may receive a separate Notice, a separate e-mail or a separate voting instruction card for each brokerage account in which you hold shares. If you are a stockholder of record and your shares are registered in more than one name, you may receive more than one Notice, more than one e-mail or more than one proxy card.
To vote all of your shares by proxy, you must complete, sign, date and return each proxy card and voting instruction card that you receive and vote over the Internet the shares represented by each Notice that you receive (unless you have requested and received a proxy card or voting instruction card for the shares represented by one or more of those Notices).
Who Is Soliciting My Proxy and Who is Paying for the Cost of This Proxy Solicitation?
The Board of IPG is soliciting your proxy to vote at the Annual Meeting. IPG will bear the expense of preparing, posting to the Internet, printing and mailing proxy materials, as well as the cost of any required solicitation. We may also reimburse banks, brokers and other custodians, nominees and fiduciaries for reasonable expenses incurred in forwarding proxy materials to beneficial owners of our stock and obtaining their proxies. In addition to the mailing of proxy materials, the solicitation of proxies may be made in person, by telephone, or by electronic communication by our directors, officers or employees, without additional compensation, on our behalf. We have also retained Innisfree M&A Incorporated, an independent proxy solicitation firm, to assist us in soliciting proxies. We will pay Innisfree M&A Incorporated a fee of up to $15,000, plus reimbursement of certain out-of-pocket expenses for these services.

Questions and Answers About the Meeting and Voting

Who Counts the Votes?
We have engaged Computershare, N.A. as our independent agent to receive and tabulate stockholder votes. Computershare, N.A. will separately tabulate “For” and “Against” votes, abstentions and broker non-votes. Computershare, N.A. will also act as independent election inspector to certify the results, determine the existence of a quorum and the validity of proxies and ballots, and perform any other acts required under the General Corporation Law of Delaware.
How Can I Vote?
Most stockholders have a choice of voting in one of four ways:
via the Internet,
using a toll-free telephone number,
completing a proxy/voting instruction card and mailing it in the postage-paid envelope provided or
in person at the meeting.
The telephone and Internet voting facilities for stockholders of record will close at 1:00 a.m. Central Time on May 28, 2020. The Internet and telephone voting procedures are designed to authenticate stockholders by use of a control number and to allow you to confirm that your instructions have been properly recorded.
If you hold your shares in “street name,” your bank, broker or other nominee will send you a separate package describing the procedures and options for voting your shares. Please read this information carefully. If you hold your shares in “street name,” and wish to vote in person at the Annual Meeting, you must obtain a “legal proxy” from the organization that holds your shares. A legal proxy is a written document that will authorize you to vote your shares held in “street name” at the Annual Meeting. Please contact the organization that holds your shares for instructions regarding obtaining a legal proxy. You must bring a copy of the legal proxy to the Annual Meeting and ask for a ballot when you arrive.
What Is the Quorum Required to Transact Business?
At the close of business on April 1, 2020, the record date, there were 53,142,181 shares of our common stock outstanding. Our bylaws require that a majority of our common stock be represented, in person or by proxy, at the Annual Meeting in order to constitute the quorum we need to transact business at the meeting. We will count broker non-votes and proxies marked “abstain” as present in determining whether a quorum exists.
