We demonstrate the importance we place on these values through our goal setting and performance management process as well as providing ethics training to employees every year.

Along with the TTM Values and our Leadership Principles, we discuss and act in accordance with, and provide annual training for, our Code of Conduct, which outlines our expectations and provides guidance for all employees. Our Code of Conduct includes topics such as anti-corruption, discrimination, harassment, privacy, appropriate use of company assets, protecting confidential information, and reporting Code of Conduct violations. Our Code of Conduct reinforces the importance of fostering an open, welcoming environment in which all employees have a voice and a confidential outlet to raise concerns regarding potential violations.

Our commitment to our communities is demonstrated through our volunteer efforts, charitable donations, and sponsorships. Our facilities in the communities that they reside each choose local charitable organizations to affiliate with that best reflect the Company’s values. Some examples of the charities that our facilities contribute to locally are: Second Harvest Food Bank, Toys for Tots, United Way, Ronald McDonald House, and Habitat for Humanity.

In addition, the Company maintains high standards for all employees worldwide which include reasonable work hours and time off, no child labor, no forced labor, equal opportunity employment, and a professional work environment that does not tolerate any form of harassment or discrimination. The Company and its employees strive to achieve and maintain a positive work environment. In addition, the Company emphasizes health and wellness programs targeted to educate employees on healthy lifestyles and promote fitness plans. We review employee turnover rates paying particular attention to supervisor and technical retention. We believe the emphasis we place on selecting, training and coaching supervisors positively impacts their ability to lead people. Our leadership principles of communications, collaboration and career development are designed to improve the employee experience and strengthen working relationships. Through internal surveys, it is clear our employees value their relationships with their supervisors, career opportunities and the corporate culture.

Employee Health & Safety.    TTM moved quickly at the onset of the COVID-19 pandemic to ensure a safe environment for our employees by activating our global pandemic response plan. Applying early lessons learned from our Asia teams helped shape and guide our progressive safety protocols for the remainder of the Company. Our regional leadership teams, with guidance from corporate, developed and implemented safeguards consisting of policies, procedures, and lessons learned reports covering: COVID-19 symptom awareness, effective hygiene practices, travel restrictions, visitor vetting and screening, social distancing, face covering expectations, temperature and health screening, work-from-home requirements, enhanced workplace cleaning, and large-scale decontamination. Notable achievements from 2020 include:

Management Policies and Systems and Communication.    How we manage and communicate to our employee base is essential in delivering against our strategy. At TTM, a key differentiator is our culture, which has been shaped through considerable thought and energy. Our culture has served us well as we integrate acquired companies and optimize our organizational structures and teams to better serve our customers. The following elements underpin our culture:

In 2020, we pivoted to a virtual platform to hold our town hall sessions, change agent network meetings, and quarterly business updates with management teams. Our change agent network was created to improve communications from the factory and office floor up to the senior management team. We select several employees within each site who are respected, influential and representative of the employee base to serve as change agents. This network discusses and then communicates the key initiatives within the sites in addition to raising employee concerns. Additionally, these teams prioritize site initiatives around community activities, site improvement projects, recognition programs, and new communication methods.

Talent Development & Acquisition.    Talent development is a collective and continuous effort of all of our people managers. We engage in regular talent reviews to calibrate on performance and potential development gaps and progress, and evaluate the depth and strength of our integrated succession plans. Our approach to learning is a continuous one, regardless of experience level or tenure. We extend leadership development programs with individually tailored development plans anchored in dedicated coaching and separate internal mentors. Additionally, we extend competency-based training, sponsor job rotations, and form project teams comprised of emerging talents. In 2020, we expanded our online learning platforms, offerings, and tools, as we continued our effort to build a global learning management system. While we primarily develop internal talent for expanded roles, we have curated an annual summer technical internship program most recently focused on robotics and automation. Coupled with co-op programs in some locations, this technical talent pipeline feeds our succession planning efforts. We provide tuition reimbursement and assistance, as well as a monthly stipend to engineers to pay down student debt.

Ethical Sourcing and Supply Chain Standards.    TTM’s supply chain management urges its suppliers to maintain the values of TTM in its sourcing from responsible suppliers to meet the needs of TTM’s customers. TTM requires that all suppliers engage in ethical business practices, institute standards and policies to follow those practices, and actively works with suppliers in a shared commitment to meet our customers’ requirements. Our suppliers are required to follow terms of confidentiality with respect to intellectual property rights of not only TTM, but also those of other third parties. TTM maintains a robust conflict minerals program, with an emphasis on compliance with the Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and to source conflict minerals in compliance with such law. Suppliers are required to adhere to the values and principals of TTM’s Code of Conduct, which establishes our expectations for suppliers in the areas of labor and human rights, environment, health and safety, ethics and management systems. At least annually, each supplier is reminded of the need to avoid the acceptance of improper gifts as well as their need for absolute compliance with the Code of Conduct and its key values of Integrity, Responsibility and Honesty. In addition, with each purchase of materials or goods, suppliers are required to comply with all applicable laws and regulations, including but

not limited to the Foreign Corrupt Practices Act, in order to prevent fraud, bribery or corruption, and a hotline is used to allow anyone to report a potential violation. TTM also specifically prohibits child labor, forced labor (including slavery and human trafficking), unfair wages and working hours, discrimination and denying freedom of association for itself as well as its supply chain. Finally, TTM actively takes into account steps for itself as well as its suppliers to minimize any negative impact on the environment, seek to reduce waste and hazardous materials, and ensure compliance with all applicable regulations and laws.

Overall, TTM takes a holistic approach with its suppliers to ensure a supply chain that is ethical, abides by basic human rights, takes environmental obligations seriously, and maintains the health and welfare of its workforce. This policy is intended to ensure that TTM sources products in an ethical and consistent manner, while supporting suppliers in their objectives to improve their social and environmental practices.

Corporate Governance.    A key component of our success is a strong foundation of Corporate Governance practices and policies that promote transparency, accountability and engagement exemplified by our Board of Directors. We maintain our Corporate Governance Guidelines to provide direction to our Board of Directors and Senior Management on topics such as board member qualifications, the evaluation process for the CEO and board members and reporting conflicts of interest. In addition to the Guidelines and the strong governance practices that we employ that are described throughout this Proxy Statement, TTM also maintains a Code of Ethics for the CEO and Senior Financial Officers. Further, each committee of the Board of Directors has a charter. All of these documents are available on TTM’s website at https://investors.ttm.com/corporate-governance/highlights.

Meetings of the Board of Directors

Our boardBoard of directorsDirectors held seven meetings (regular and special) during 2018.2020. All of our directors attended more than 75% of the aggregate of (i) the total number of meetings of the boardBoard of directorsDirectors held during 2018,2020, and (ii) the total number of meetings held by all committees of our boardBoard of directorsDirectors on which such person served during 2018.2020. We have adopted a policy encouraging each of our directors to attend each annual meeting of stockholders and, to the extent reasonably practicable, we regularly schedule a meeting of the boardBoard of directorsDirectors on the same day as the annual meeting of stockholders. All of our directors attended the 20182020 annual meeting of stockholders.

Committees of the Board of Directors

The members and nomineesAfter the 2021 annual meeting of stockholders, the composition of our board will change. With the retirement of Mr. Klatell, the number of directors serving on our Board of Directors will reduce from nine to eight. Our Board of Directors has determined that if Mr. Geveden is re-elected at the 2021 annual meeting, immediately upon the retirement of Mr. Klatell, the Board of Directors will appoint Mr. Geveden to take the position as Chairman of the Board andof Directors. Further, our Board of Directors will change the membership of the committees of the Board of Directors after the annual meeting to replace Mr. Klatell on which they serve asthe committees that he currently serves.

As of the date of this Proxy Statement, the members and nominees of our Board of Directors and the committees of our Board of Directors on which they serve, are identified below:

Audit Committee.    Our audit committee reviewsAudit Committee provides assistance to the Company’s Board of Directors in fulfilling its responsibility to shareholders, the investment community and monitors our corporategovernmental agencies that regulate the activities of the Company with respect to oversight of: (i) the integrity of the Company’s accounting and financial reporting process, financial statements and our external audit, including, among other things, ourfinancial statement audits; (ii) the Company’s compliance with legal and regulatory requirements; (iii).the independent auditor’s qualifications, independence and performance; (iv) the performance of the Company’s internal audit function; and (v) the performance of the Company’s internal accounting controls, disclosure controls and procedures, and internal control functions, the results and scope of the annual

regarding the role of compensation consultants and executive officers in assisting our compensation committee in determining the amount or form of executive compensation may be found in “Compensation Discussion and Analysis” below. The current members of our compensation committee are Messrs. KlatellGeveden (chairman) and GevedenKlatell and Ms. Lenard, each of whom is an independent director under NASDAQ listing standards as well as under SEC rules. The compensation committee held eightseven meetings during 2018.2020.

Our compensation committee has a written charter that delineates its responsibilities, a full copy of which is posted on our website atwww.ttm.com. https://investors.ttm.com/corporate-governance/highlights.

Compensation Consultant and its Affiliates.    Mercer, LLC (“Mercer”) was retained by our compensation committee to provide an independent review of the Company’s board and executive compensation programs, including an analysis of the competitive market for 2018.2020. Our compensation committee assessed the independence of Mercer pursuant to SEC and NASDAQ rules and concluded that Mercer is independent and that the work of Mercer has not raised any conflict of interest. For further discussion of the work conducted by Mercer as our compensation consultant, see “Compensation Discussion and Analysis – Role of the Compensation Committee.”

Nominating and Corporate Governance Committee.    The nominating and corporate governance committee oversees the selection and composition of our Board of Directors and oversees the management continuity planning processes. It establishes, monitors, and recommends the purpose, structure, and operations of the various committees of our Board of Directors, the criteria and qualifications for membership of each board committee, and recommends whether rotations or term limits are appropriate for the chair or committee members of the various committees. In addition, the nominating and corporate governance committee recommends individuals to stand for election as directors and recommends directors to serve on each committee as a member or as chair of the committee. The nominating and corporate governance committee reviews director compensation and recommends changes in director compensation to our Board of Directors with the support of our compensation consultants, Mercer. The nominating and corporate governance committee reviews and makes recommendations regarding our governing documents (including our certificate of incorporation and bylaws) and our corporate governance principles. The nominating and corporate governance committee is also responsible for considering policies relating to the meetings of our Board of Directors and considers questions of independence and possible conflicts of interest of members of our Board of Directors and executive officers. Finally, the nominating and corporate governance committee oversees the evaluation of our Board of Directors and management.

The nominating and corporate governance committee will consider persons recommended by stockholders for inclusion as nominees for election to our Board of Directors if the information required by our bylaws is submitted in writing in a timely manner and addressed and delivered to our Company’s secretary at 200 East Sandpointe, Suite 400, Santa Ana, California 92707. A stockholder who intends to recommend a nominee to our Board of Directors must provide (a) all information relating to the individual subject to the nomination that is required to be disclosed in opposition proxy statements for election of directors filed by stockholders, at their own expense, in a contested election, or as otherwise required under Regulation 14A under the Securities Exchange Act of 1934, as amended (referred to as the Exchange Act), and (b) the individual’s written consent to being named in a proxy statement as a nominee and to serving as a director if elected. The stockholder making the nomination must also provide the information required by our bylaws relating to such stockholder, including information pertaining to ownership of our capital stock, and must make certain representations relating to voting intent and delivery of proxies. The stockholder’s nominee must also deliver to our secretary a written questionnaire with respect to the background and qualification of such person and the background of any other person or entity on whose behalf the nomination is being made. The questionnaire is available from our secretary upon written request and upon the requesting person’s providing certain written representations required by our bylaws.

The nominating and corporate governance committee identifies and evaluates nominees for our Board of Directors, including nominees recommended by stockholders, based on numerous factors it considers appropriate, some of which may include strength of character, mature judgment, career specialization, relevant technical skills, diversity, and the extent to which the nominee would fill a present need on our Board of Directors. The nominating and corporate governance committee evaluates nominees for director in the same manner, regardless of whether the nominee is recommended by a stockholder or other person or entity.

In making its selection of director candidates, our nominating and corporate governance committee bears in mind that the foremost responsibility of a director is to represent the interests of our stockholders as a whole. Directors are expected to exemplify the highest standards of personal and professional integrity and to constructively challenge management through their active participation and questioning. In consideration of these expectations, the nominating and corporate governance committee seeks directors with established strong professional reputations and expertise in areas relevant to the strategy and operations of our business. The activities and associations of candidates are reviewed for any legal impediment, conflict of interest, or other consideration that might prevent service on our Board of Directors.

The charter of our nominating and corporate governance committee provides that the value of diversity on our Board of Directors should be considered, and the nominating and corporate governance committee includes diversity as one of its criteria for board composition. While we do not have a formal policy outlining the diversity standards to be considered when evaluating director candidates, our objective is to foster diversity of thought on our Board of Directors. To accomplish that objective, the nominating and corporate governance committee considers ethnic and gender diversity, as well as differences in perspective, professional experience, education, national security qualifications, skill and other qualities in the context of the needs of our Board of Directors. The nominating and corporate governance committee evaluates its effectiveness in achieving diversity on the Board of Directors through its annual review of board member composition, which includes an assessment of directors’ ethnicity, gender, and industry experience, prior to recommending nominees for election.

The current members of our nominating and corporate governance committee are Messrs. Mayer (chairman) and Klatell and Ms. England, each of whom is an independent director under NASDAQ listing standards as well as under SEC rules. The nominating and corporate governance committee held five meetings during 2020.

Our nominating and corporate governance committee has a written charter that delineates its responsibilities, a full copy of which is posted on our website at https://investors.ttm.com/corporate-governance/highlights.

Government Security Committee.    As previously disclosed in our filings with the SEC, a portion of our business consists of manufacturing defense and defense-related items for various departments and agencies of the U.S. government, including the U.S. Department of Defense, which requires that we maintain facility security clearances under the National Industrial Security Program (referred to as NISP)(“NISP”). The NISP requires that a corporation maintaining a facility security clearance take steps to mitigate foreign ownership, control, or influence (referred to as FOCI). As we have also previously reported that we are party to a Special Security Agreement with the United States Defense Security Service. That special

Our Board of our board of directors.

Our board of directorsDirectors currently has eight independent members and twoone non-independent members,member, specifically Mr. Edman, our president and chief executive officer,officer. After the retirement of Mr. Klatell on May 12^th, 2021, our board will have seven independent directors and Mr. Tang.one non-independent member. A number of our independent board members are currently serving or have served as members of senior management of other public companies or governmental agencies and have served as directors of other public companies. We believe that the number of independent, experienced directors that make up our board, along with the independent oversight of the boardBoard of directorsDirectors by anon-executive chairman, benefits our Company and our stockholders.

The special security agreement to which we are a party establishes certain criteria for the qualifications of our directors and the composition of our boardBoard of directors,Directors, and also requires that a certain number of directors have strong national security qualifications, have no prior relationship with certain “affiliates” described in the special security agreement, and be U.S. citizens holding or eligible to hold personnel security clearances. Our current boardBoard of directorsDirectors meets the composition criteria and our board has determined to maintain a classified Board of Directors partly because it is critical that we meet this important criteria.

We believe that we have a strong corporate governance structure that ensures independent discussion among, evaluation of, and communication with and access to, senior management. With the exception of our government security committee of which Mr. Edman is a member, all of our board committees are composed solely of independent directors, which provide independent oversight of management. Also, our corporate governance guidelines provide that our independent directors will meet in executive session not less frequently than quarterly.

Risk Management and Oversight Process

Process.    While our management is primarily responsible for managing risk, our boardBoard of directorsDirectors and each of its committees play a role in overseeing our risk management practices. Our full boardBoard of directorsDirectors is ultimately responsible for risk oversight, and it discharges this responsibility by, among other things, receiving regular reports from our management concerning our business and the material risks that our Company faces. Our boardBoard of directorsDirectors annually reviews key enterprise risks identified by management, such as financial, reputational, safety and security, cyber security, social responsibility, environmental and compliance risks, and it monitors key risks through reports and discussions regarding key risk areas at meetings of our boardBoard of directorsDirectors and in committee meetings. Our boardBoard of directorsDirectors also focuses on specific strategic and emerging risks in periodic strategy reviews. Our boardBoard of directorsDirectors annually reviews and approves our corporate strategy and goals and our capital budgets, and in connection with that review, it considers risks associated with our Company.

Through the activities of our audit, compensation, nominating and corporate governance, and government security committees, as well as the full boardBoard of directors’Directors’ interactions with management concerning our business and the material risks that may impact our Company, the boardBoard of directorsDirectors and each respective committee is able to monitor our risk management process and offer critical insights to our management.

Our Insider Trading Policy prohibits the ability of our employees generally to purchase financial instruments (including prepaid variable forward contracts, equity swaps, collars, and exchange funds), or otherwise engage in transactions, that hedge or offset, or are designed to hedge or offset, any decrease in the market value of our equity securities. Our officers and directors are also further prohibited from engaging in these types of hedging transactions. See “Director Compensation – Stock Ownership, Hedging and Pledging Policies” and “Compensation Discussion and Analysis – Compensation Overview – Alignment of Compensation and Performance – Compensation Practices.”

Related Person Transaction Policies and Procedures

Procedures.    It is the responsibility of our full boardBoard of directorsDirectors and our audit committee to review and approve related party transactions. It is our management’s responsibility to bring such related party transactions to the attention of our boardBoard of directorsDirectors and members of our audit committee. From time to time, our nominating and corporate governance committee, in accordance with its charter, will also review potential conflict of interest transactions involving members of our boardBoard of directorsDirectors and our executive officers.

In accordance with our corporate governance guidelines, any monetary engagement (other than director or employee compensation or transactions which would not require disclosure under Item 404 of RegulationS-K) (a) between a director (including any entity of which the director is a director or executive officer and any member of a director’s family as defined in NASDAQ rules) and our Company or any of its affiliates or members of senior management or their families, and (b) between executive officers of our Company (as designated by our boardBoard of directors)Directors) and our Company or any of its affiliates, is subject to the approval of our audit committee or our independent directors. Each of our directors and executive officers must notify our boardBoard of directorsDirectors in advance of entering into any such transaction.

Our corporate governance guidelines task our boardBoard of directors,Directors, in consultation with our nominating and corporate governance committee, with reviewing annually the relationships that each director has with us, directly or indirectly.

directors meet the stock ownership guidelines as of December 28, 2020. In addition, the board recently adopted stock ownership guidelines for the Chief Executive Officer and his direct reports. For a full description of such guidelines, see page 39.

DIRECTOR COMPENSATION

Effective with the second quarter of 2018,2020, ournon-employee directors receive the following compensation: an annual cash retainer of $68,000, an annual cash retainer of $9,000 for each board committee of which such director is a member (except for the government security committee), and reimbursement of expenses relating to attendance at board and board committee meetings. In addition, the chairmanChairman of the boardBoard receives an annual cash retainer of an additional $68,000, and the chairmen of our various board committees receive annual cash retainers as follows: $22,000 to our audit committee chairman, $17,000 to our compensation committee chairman, $13,000 to our government security committee chairman, and $12,000 to our nominating and corporate governance committee chairman. Annually, our nominating and corporate governance committee, in consultation with Mercer, reviews our board compensation against the board compensation of our peer companies to develop a reasonable board compensation package. In May of 2020, due to the uncertain nature of the impact that the COVID-19 pandemic may have on our business, our Board of Directors determined not to increase board member compensation in 2020.

Upon initial election, eachnon-employee director receiveshas historically received an option to purchase 20,000 shares of our common stock. The options provided to thenon-employee directors expire on the tenth anniversary of the grant date and vest over a four-year period. In May 2018,2020, the chairmanChairman of the boardBoard received restricted stock units (referred to as RSUs)(“RSUs”) having a value on the award date of $140,000$170,000 and eachnon-employee director received restricted stock units having a value on the award date of $120,000$130,000 based upon the average closing price of our common stock over thesix-month period preceding the grant date. The RSUs awarded to thenon-employee directors vest in full on the first anniversary of the grant date; however, in an effort to further align board members’ interests with those of our stockholders, delivery of the shares of common stock underlying the RSUs is deferred until retirement from the boardBoard of directorsDirectors (or until one year after retirement in the case of certain prior grants).

Stock Ownership, Hedging and Pledging Policies.  Our board of directors recognizes that stock ownership by directors may strengthen their commitment to the long-term future of our Company and further align their interests with those of our stockholders. Accordingly, our corporate governance guidelines provide that our independent directors are ordinarily expected over time to beneficially own shares of our common stock (including shares owned outright, unvested shares, restricted stock units, and stock options) having a value of at least three times their annual retainer, and as our directors are subject to our insider trading policy, they are prohibited from pledging or hedging their shares. All of our directors, except for Ms. Lenard and Mr. Geveden, who joined our board in 2018, meet the stock ownership guidelines as of March 11, 2019. In addition, the board recently adopted stock ownership guidelines for the Chief Executive Officer and his direct reports. For a full description of such guidelines, see page 38.

Mr. Edman is not compensated for his service as a director. Mr. Edman’s compensation as our chief executive officer and president is described below under “Compensation Discussion and Analysis” and “Executive Compensation.” For the period between January 1 and March 31, 2018, Mr. Tang received total compensation of $77,281 for his service as Managing Director – Asia Pacific Region of one of the Company’s Hong Kong subsidiaries, which total compensation consisted of the following: (i) base salary of $63,638, (ii) an additionalpro-rata component of base salary in the amount of $10,461 paid in 2018 as is consistent with competitive practices in the region in recognition of the Chinese New Year, and (iii) $3,182 of contributions made by us on Mr. Tang’s behalf to the Mandatory Provident Fund, a savings program for the retirement of residents in Hong Kong. As of March 31, 2018, Mr. Tang and the Company agreed that he would no longer be an employee of the Company’s Hong Kong subsidiary. The Company and Mr. Tang agreed as part of his separation from employment, that Mr. Tang would receive a severance payment of $150,000 USD and unused leave pay in the amount of $42,774 USD. The amounts paid to Mr. Tang were paid in Hong Kong Dollars (HKD) and converted to U.S. Dollars (USD)

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table shows the amount of each class of common stock beneficially owned as of March 11, 201915, 2021 by (a) each of our directors and named executive officers; (b) all of our directors and executive officers as a group; and (c) each person known by us to own beneficially more than five percent of our outstanding common stock.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act requires our directors, officers, and persons who own more than 10% of a registered class of our securities to file reports of ownership and changes in ownership with the SEC. Directors, officers, and greater than 10% stockholders are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file.

Based solely upon our review of the copies of such forms that we received during the fiscal year ended December 31, 2018, and written representations that no other reports were required, we believe that each person who at any time during such year was a director, officer, or beneficial owner of more than 10% of our common stock complied with all Section 16(a) filing requirements during the fiscal year ended December 31, 2018.

COMPENSATION DISCUSSION AND ANALYSIS

The Compensation Discussion and Analysis, or CD&A, describes and analyzes our executive compensation philosophy and program in the context of the compensation paid during the last fiscal year to our chief executive officer, our chief financial officer, and each of our three other highest paid executive officers (collectively referred to as our named executive officers or NEOs).

Compensation Overview – Alignment of Compensation and Performance

Our goal is to tie the Company’s compensation closely with performance. The information below provides an executive summary of the Company’s financial performance for fiscal year 20182020 and how pay is aligned with performance. In 2020, TTM divested its mobility business in order to decrease the Company’s exposure to dependence on a single customer in the volatile consumer market. By this action, the Company expects it will increase its overall profitability while decreasing its total revenue in the short term. Also in 2020, the Company determined that, due to the uncertain nature of the impact that the COVID-19 pandemic may have on our business, that there would not be any base compensation increase for any employees with the title of Vice President or above, including the Company’s CEO and all NEO’s.

KEY ACCOMPLISHMENTS IN 20182020

TTM’s commitment to its strategy of diversification, differentiation and discipline led to TTM’s continued growth and financial strength in 2018. In an effort to further differentiate our product and service offerings to our customers, we purchased Anaren, Inc. in 2018 and have successfully integrated it into our organization. For 2018, our growth markets were aerospace and defense, computing, and medical, industrial and instrumentation, which offset the declines in our cellular phone, automotive and networking and communications end markets.2020. Due to disciplined operations and cost controls, we generated Non GAAPNon-GAAP net income of $190.4$116.7 million in 2018.2020.

20182020 SAY ON PAY VOTE

Approximately 99.2%99.71% of the votes cast on the matter were voted “For” such advisory“say-on-pay” approval, thereby providing the compensation committee with verification that its compensation practices align the interests of the Company’s executives with those of the Company’s stockholders.

Executive Compensation Philosophy and Objectives

Our executive compensation philosophy, which is established by the compensation committee of our boardBoard of directors,Directors, is intended to attract, motivate, and retain executives and reward the creation of stockholder value. We seek to provide executive compensation packages that are competitive with comparable companies and reward the achievement of short-term and long-term performance goals.

We use a combination of fixed and variable compensation programs to reward and incentivize strong performance, as well as to align the interests of our executives with those of our stockholders. We generally target total compensation between the 25th and 50th percentile of comparable companies. We believe that this philosophy will continue to enable us to remain competitive in attracting and retaining qualified executive officers while avoiding paying amounts in excess of what we believe is necessary to attract and retain such executive officers. However, our compensation committee’s decisions on target compensation for specific individuals are also influenced by a variety of additional factors, including compensation practices of businesses acquired by us and Company and individual performance.

Each year our compensation committee, together with our senior management, establishes performance targets for short-term and long-term incentive plans that require the achievement of significant financial results. Each year our compensation committee determines compensation by assessing prior year performance against these established financial targets, as well as other factors such as the compensation paid by comparable companies, achievement of strategic objectives, improvements in market share and the professional development and potential of individual officers. Ultimately, the amount of compensation awarded to our executives is determined based on performance and what our compensation committee believes is in the best interests of our stockholders.

We believe that our use of restricted stock units (referred to as RSUs) and performance-based restricted stock units, (referred to as PRUs), together with an annual incentive bonus program that is based on various combinations of global operating income, business unit operating income, and global cash flow from operations as a percentage of revenue,

officer, thenon-employee members of our boardBoard of directors.Directors. These decisions are based not only on our compensation committee’s deliberations, but also on input requested from outside advisors, including our compensation committee’s outside compensation consultant, with respect to, among other things, market data analyses. The final decisions relating to our chief executive officer’s compensation have historically been based on recommendations of our compensation committee and included discussions with and approval by all of ournon-employee directors without the presence of our chief executive officer or other management. Our compensation committee typically discusses proposals for our chief executive officer’s compensation package with him but always makes final decisions regarding his compensation when he is not present. Decisions regarding other executive officers have typically been made by our compensation committee after considering recommendations from our chief executive officer.

Compensation Consultant.    Our compensation committee has historically engaged the services of an outside compensation consultant to provide independent advice in connection with making executive compensation determinations. The chairman of our compensation committee, in consultation with other committee members, defines the scope of any consultant’s engagement and related responsibilities. These responsibilities may include, among other things, advising on issues of executive compensation and equity compensation structure and assisting in the preparation of compensation disclosure for inclusion in our SEC filings. In fulfilling its responsibilities, the outside compensation consultant may interact with management or our other outside advisors to the extent necessary or appropriate.

Our compensation committee continued our engagement with Mercer with respect to 20182020 compensation matters. Mercer (the “Compensation Consultant”) was retained to provide an independent review of the Company’s executive compensation programs, including an analysis of both the competitive market and the design of the programs.

Compensation Structure

Although the final structure may vary from year to year and officer to officer, our compensation committee utilizes three main components for executive officer compensation: base salary, annual incentive bonus and long-term equity incentives.

Pay Mix.    In determining the allocation each year among base salary, annual incentive bonus, and long-term equity incentive compensation, our compensation committee considers the following factors: our short-term and long-term business objectives, competitive trends within our industry, and the importance of creating a performance-based environment that ties a significant portion of each executive officer’s compensation to the achievement of performance targets and corporate objectives. When considering a proposed compensation package for an executive officer, our compensation committee considers the compensation package as a whole, including each element of total compensation. We have nopre-established policy for allocating between either cash andnon-cash or short-term and long-term compensation.

This peer group is not used for the stock price performance graph included in our Annual Report on Form10-K for the year ended December 31, 2018. That Form10-K performance graph compares the cumulative total stockholder return on our common stock against the cumulative total return on the NASDAQ Composite Index and the Dow Jones U.S. Electrical Components & Equipment Index.

Mercer recommended the use of peer group data (where available) combined with data obtained from a broader compensation survey conducted by Radford (the “Radford Survey”) for comparing compensation of our executive officers. Mercer recommended the use of the Radford Survey for companies in the semiconductor, computer storage and peripherals, and communications equipment industries with approximate annual revenues between $1.0 billion and $3.0 billion, in order to align with the criteria used to select our 2018 Peer Group.

As discussed above, our compensation committee has historically targeted the compensation levels of our executive officers between the 25th and 50th percentile of comparable officers at comparable companies, as derived from both peer group data and broader composite survey data. Our compensation committee may have varied from this target range for various elements of compensation depending on the executive officer’s job performance, skill set, level of responsibilities, prior compensation and business conditions. The compensation for our executive officers discussed herein for 2018 falls generally within this targeted range.

Our compensation committee intends to continue its practice of retaining consultants from time to time, as it deems appropriate, to advise it with respect to its policies and to provide compensation data from comparable companies.

Risk Management Considerations.    Our compensation committee believes that our performance-based bonus and equity programs for all management employees, including our executive officers, provide incentives to create long-term stockholder value. Several elements of the programs are also designed to discourage behavior that leads to excessive risk:

In response to the recommendations of management, our compensation committee based the Company’s incentive bonus plan on several metrics that the committee believed most closely aligned the executive’s incentive pay with metrics that the executive is responsible for managing. For 2018,2020, the incentive bonus for Messrs. Edman, Schull, Barber and Weber is allocated based upon 72% global operating income and 18% global cash flow from operations as a percentage of revenue. For Mr. Soder, the incentive bonus takes into account the performance of the Business Unit that he directs. For each executive, 10% of the award is based on individual goals. The below chart reflects the weight of each performance metricmetric.
