The table below sets forth the beneficial ownership of shares of Lam common stock by: (1) each person or entity who we believe based on our review of filings made with the United States Securities and Exchange Commission, or the “SEC,” beneficially owned as of September 11, 2017, more than 5% of Lam’s common stock on the date set forth below; (2) each current director of the Company; (3) each NEO identified below in the “Compensation Matters – Executive Compensation and Other Information – Compensation Discussion and Analysis” section; and (4) all current directors and current executive officers as a group. With the exception

of 5% owners, and unless otherwise noted, the information below reflects holdings as of September 11, 2017, which is the Record Date for the 2017 annual meeting and the most recent practicable date for determining ownership. For 5% owners, holdings are as of the dates of their most recent ownership reports filed with the SEC, which are the most practicable dates for determining their holdings. The percentage of the class owned is calculated using 162,496,503 as the number of shares of Lam common stock outstanding on September 11, 2017.

Section 16(a) of the Exchange Act requires our executive officers, directors, and people who own more than 10% of a registered class of our equity securities to file an initial report of ownership (on a Form 3) and reports on subsequent changes in ownership (on Forms 4 or 5) with the SEC by specified due dates. Our executive officers, directors, and greater-than-10% stockholders are also required by SEC rules

to furnish us with copies of all section 16(a) forms they file. We are required to disclose in this proxy statement any failure to file any of these reports on a timely basis. Based solely on our review of the copies of the forms that we received from the filers, and on written representations from certain reporting persons, we believe that all of these requirements were satisfied during fiscal year 2017.

Our Board and members of management are committed to responsible corporate governance to manage the Company for the long-term benefit of its stockholders. To that end, the Board and management periodically review and update, as appropriate, the Company’s corporate governance policies and practices. As part of that process, the Board and management consider the requirements of federal and state law, including rules and regulations of the SEC; the listing standards for the Nasdaq Global Select Market, or “Nasdaq;” published guidelines and recommendations of proxy advisory firms; published guidelines of some of our top stockholders; published guidelines of other selected public companies; and any feedback we receive from our stockholders. A list of key corporate governance practices is provided in the “Proxy Statement Summary” above.

Corporate Governance Policies

We have instituted a variety of policies and procedures to foster and maintain responsible corporate governance, including the following:

Board committee charters. Each of the Board’s audit, compensation, and nominating and governance committees has a written charter adopted by the Board that establishes practices and procedures for the committee in accordance with applicable corporate governance rules and regulations. Each committee reviews its charter annually and recommends changes to the Board, as appropriate. Each committee charter is available on the Investors section of our website at http://investor.lamresearch.com/corporate-governance.cfm. The content on any website referred to in this proxy statement is not a part of or incorporated by reference in this proxy statement unless expressly noted. Also see “Board Committees” below for additional information regarding these committees.

Corporate governance guidelines. We adhere to written corporate governance guidelines, adopted by the Board and reviewed annually by the nominating and governance committee and the Board. Selected provisions of the guidelines are discussed below, including in the “Board Nomination Policies and Procedures,” “Director Independence Policies,” and “Other Governance Practices” sections below. The corporate governance guidelines are available on the Investors section of our website at http://investor.lamresearch.com/corporate-governance.cfm.

Corporate code of ethics. We maintain a code of ethics that applies to all employees, officers, and members of the Board.

The code of ethics establishes standards reasonably necessary to promote honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships, and full, fair, accurate, timely, and understandable disclosure in the periodic reports we file with the SEC and in other public communications. We will promptly disclose to the public any amendments to, or waivers from, any provision of the code of ethics to the extent required by applicable laws. We intend to make this public disclosure by posting the relevant material on our website, to the extent permitted by applicable laws. A copy of the code of ethics is available on the Investors section of our website at http://investor.lamresearch.com/corporate-governance.cfm.

Global standards of business conduct policy. We maintain written standards of appropriate conduct in a variety of business situations that apply to our worldwide workforce. Among other things, these global standards of business conduct address relationships with one another, relationships with Lam (including conflicts of interest, safeguarding of Company assets, and protection of confidential information), and relationships with other companies and stakeholders (including anti-corruption).

Insider trading policy. Our insider trading policy restricts the trading of Company stock by our directors, officers, and employees, and includes provisions addressing insider blackout periods and prohibiting hedges and pledges of Company stock.

Board Nomination Policies and Procedures

Board membership criteria. Under our corporate governance guidelines, the nominating and governance committee is responsible for assessing the appropriate balance of experience, skills, and characteristics required for the Board and for recommending director nominees to the independent directors.

The guidelines direct the committee to consider all factors it considers appropriate. The committee need not consider all of the same factors for every candidate. Factors to be considered may include but are not limited to: experience; business acumen; wisdom; integrity; judgment; the ability to make independent analytical inquiries; the ability to understand the Company’s business environment; the candidate’s willingness and ability to devote adequate time to board duties; specific skills, background, or experience considered necessary or desirable for board or committee service; specific experiences with other businesses or

organizations that may be relevant to the Company or its industry; diversity with respect to any attribute(s) the Board considers appropriate, including geographic, gender, age, and ethnic diversity; and the interplay of a candidate’s experiences and skills with those of other Board members.

The specific skills, background, and experiences that are evaluated in connection with board service include (but are not limited to or required):

The Board and the nominating and governance committee regard board refreshment as important, and strive to maintain an appropriate balance of tenure, turnover, diversity, and skills on the Board.

For many years, the composition of the Board has reflected the Board’s commitment to diversity. For example, the Board has had at least two female directors since 2006, and over the last 10 years has expanded the experiences and areas of substantive expertise of the directors, as illustrated by the information provided in their biographies under “Voting Proposals – Proposal No. 1: Election of Directors – 2017 Nominees for Director” below. Most recently, the Board has increased its geographic diversity with the appointment of two directors whose careers include significant leadership

experience with major non-U.S. customers and who reside in Asia.

Regarding tenure, the Board believes that new perspectives and ideas are important to a forward-looking and strategic board as is the ability to benefit from the valuable experience and familiarity of longer-serving directors. In line with the Board’s pursuit of board refreshment and balanced tenure, including consideration of any resignations, the Board appointed two new directors within the last fiscal year, and has appointed 12 new directors in the last 10 years.

Prior to recommending the nomination of an incumbent non-employee director for reelection, the committee reviews the experiences, skills, and qualifications of the director to assess the continuing relevance of his or her experiences, skills, and qualifications to those considered necessary or desirable for the Board at that time.

To be nominated, a new or incumbent candidate must provide an irrevocable conditional resignation that will be effective upon (1) the director’s failure to receive the required majority vote at an annual meeting at which the nominee faces re-election and (2) the Board’s acceptance of such resignation. In addition, no director, after having attained the age of 75 years, may be nominated for re-election or reappointment to the Board.

Nomination procedure. The nominating and governance committee identifies, screens, evaluates, and recommends qualified candidates for appointment or election to the Board. The committee considers recommendations from a variety of sources, including search firms, Board members, executive officers, and stockholders. Nominations for election by the stockholders are made by the independent members of the Board. See “Voting Proposals – Proposal No. 1: Election of Directors – 2017 Nominees for Director” below for additional information regarding the 2017 candidates for election to the Board.

Certain provisions of our bylaws apply to the nomination or recommendation of candidates by a stockholder. For example, in February 2017, the Board amended and restated our bylaws to provide that under certain circumstances, a stockholder, or group of up to 20 stockholders, who have maintained continuous ownership of at least three percent (3%) of our common stock for at least three years may nominate and include a specified number of director nominees in our annual meeting proxy statement that cannot exceed the greater of two or 20% of the aggregate number of directors then serving on the Board (rounded down). Information regarding the nomination procedure is provided in the “Voting and Meeting Information – Other Meeting Information – Stockholder-Initiated Proposals and Nominations for 2018 Annual Meeting” section below.

Director Independence Policies

Board independence requirements. Our corporate governance guidelines require that a majority of the Board members be independent. No director will qualify as “independent” unless the Board affirmatively determines that the director qualifies as independent under the Nasdaq rules and has no relationship that would interfere with the exercise of independent judgment as a director. In addition, no non-employee director may serve as a consultant or service provider to the Company without the approval of a majority of the independent directors (and any such director’s independence must be reassessed by the full Board following such approval).

Board member independence. The Board has determined that all current directors, other than Messrs. Anstice and Newberry, are independent in accordance with Nasdaq criteria for director independence.

Board committee independence. All members of the Board’s audit, compensation, and nominating and governance committees must be non-employee or outside directors and independent in accordance with applicable Nasdaq criteria as well as, in the case of the compensation committee, applicable rules under section 162(m) of the Internal Revenue Code of 1986, as amended, or the “Code,” and Rule 16b-3 of the Securities Exchange Act of 1934, as amended, or the “Exchange Act.” See “Board Committees” below for additional information regarding these committees.

Lead independent director. Our corporate governance guidelines authorize the Board to designate a lead independent director from among the independent members. Mr. Talwalkar was appointed the lead independent director, effective August 27, 2015. See “Leadership Structure of the Board” below for information regarding the responsibilities of the lead independent director.

Executive sessions of independent directors. The Board and its audit, compensation, and nominating and governance committees hold meetings of the independent directors and committee members, without management present, as part of each regularly scheduled meeting and at any other time at the discretion of the Board or committee, as applicable.

Board access to independent advisors. The Board as a whole, and each standing Board committee separately, has the complete authority to retain, at the Company’s expense, and terminate, in their discretion, any independent consultants, counselors, or advisors as they deem necessary or appropriate to fulfill their responsibilities.

Board education program. Our corporate governance guidelines provide that directors are expected to participate in educational events sufficient to maintain their understanding of their duties as directors and to enhance their ability to fulfill their responsibilities. In addition to any external educational

opportunities that the directors find useful, the Company and the board leadership are expected to facilitate such participation by arranging for appropriate educational presentations from time to time.

Leadership Structure of the Board

The current leadership structure of the Board consists of a chairman and a lead independent director. The chairman, Mr. Newberry, served as chief executive officer of the Company from June 2005 to January 2012. The Board believes that this is the appropriate board leadership structure at this time. Lam and its stockholders benefit from having Mr. Newberry as its chairman, as he brings to bear his experience as CEO as well as his other qualifications in carrying out his responsibilities as chairman, which include (1) preparing the agenda for the Board meetings with input from the CEO, the Board, and the committee chairs; (2) upon invitation, attending meetings of any of the Board committees on which he is not a member; (3) conveying to the CEO, together with the chair of the compensation committee, the results of the CEO’s performance evaluation; (4) reviewing proposals submitted by stockholders for action at meetings of stockholders and, depending on the subject matter, determining the appropriate body, among the Board or any of the Board committees, to evaluate each proposal and making recommendations to the Board regarding action to be taken in response to such proposal; (5) performing such other duties as the Board may reasonably request from time to time; and (6) providing reports to the Board on the chairman’s activities under his agreement. The Company and its stockholders also benefit from having a lead independent director to provide independent board leadership. The lead independent director is responsible for: (1) coordinating the activities of the independent directors; (2) consulting with the chairman regarding matters such as (a) schedules of and agendas for Board meetings, (b) the quality, quantity, and timeliness of the flow of information from management, and (c) the retention of consultants who report directly to the Board; and (3) developing the agenda for and moderating executive sessions of the Board’s independent directors.

Other Governance Practices

In addition to the principal policies and procedures described above, we have established a variety of other practices to enhance our corporate governance, including the following:

Board and committee assessments. Every year, the Board conducts a self-evaluation of the Board, its committees, and the individual directors, overseen by the nominating and governance committee and generally led by the lead independent director and the chairman of the Board. From time to time, the evaluation is facilitated by an independent third-party consultant. The evaluation solicits the opinions of the directors regarding the effectiveness of the Board, committees, and individual directors in fulfilling its/their

obligations. Feedback on Board and committee effectiveness is provided to the full Board for discussion, and feedback regarding individual director performance is provided to each individual director. The Board and committees identify and hold themselves accountable for any action items stemming from the assessment. The results of the evaluations are also considered as part of the director nomination process.

Director resignation or notification of change in executive officer status. Under our corporate governance guidelines, any director who is also an executive officer of the Company must offer to submit his or her resignation as a director to the Board if the director ceases to be an executive officer of the Company. The Board may accept or decline the offer, in its discretion. The corporate governance guidelines also require a non-employee director to notify the nominating and governance committee if the director changes or retires from his or her executive position at another company. The nominating and governance committee reviews the appropriateness of the director’s continuing Board membership under the circumstances, and the director is expected to act in accordance with the nominating and governance committee’s recommendations.

Limitations on other board and committee memberships. Board members may not serve on more than four public company boards (including service on the Company’s Board). Non-employee directors who are sitting executives may not serve on more than three public company boards (including the Company’s Board). The nominating and governance committee will review the appropriateness of continued Board membership if a non-employee director who is a sitting executive serves on more than two such boards, and the director is expected to follow the recommendation of the nominating and governance committee. In addition, non-employee directors may not serve on more than three audit committees of public company boards (including the Company’s audit committee).

Director and executive stock ownership. Under the corporate governance guidelines, each director is expected to own at least the lesser of five times the value of the annual cash retainer (not including any committee chair or other supplemental retainers for directors) or 5,000 shares of Lam common stock, by the fifth anniversary of his or her initial election to the Board. Guidelines for stock ownership by designated members of the executive management team are described below under “Compensation Matters – Executive Compensation and Other Information – Compensation Discussion and Analysis.” All of our directors and designated members of our executive management team were in compliance with the Company’s applicable stock ownership guidelines at the end of fiscal year 2017 or have a period of time remaining under the program to do so.

Communications with Board members. Any stockholder who wishes to communicate directly with the Board, with any Board committee, or with any individual director regarding the

Company may write to the Board, the committee, or the director c/o Secretary, Lam Research Corporation, 4650 Cushing Parkway, Fremont, California 94538. The Secretary will forward all such communications to the appropriate director(s).

Any stockholder, employee, or other person may communicate any complaint regarding any accounting, internal accounting control, or audit matter to the attention of the Board’s audit committee by sending written correspondence by mail (to Lam Research Corporation, Attention: Board Audit Committee, P.O. Box 5010, Fremont, California 94537-5010) or by telephone (855-208-8578) or internet (through the Company’s third-party provider website at www.lamhelpline.ethicspoint.com). The audit committee has established procedures to ensure that employee complaints or concerns regarding audit or accounting matters will be received and treated anonymously (if the complaint or concern is submitted anonymously and permitted under applicable law).

Meeting Attendance

Our Board held a total of six meetings during fiscal year 2017. The number of committee meetings held is shown in Figure 6. All of the directors attended at least 75% of the aggregate number of Board meetings and meetings of Board committees on which they served during their tenure in fiscal year 2017, with the exception of Mr. Cannon due to medical reasons. We expect his attendance going forward to be consistent with prior years.

We expect our directors to attend the annual meeting of stockholders each year unless unusual circumstances make attendance impractical. All but one of the individuals who were directors as of the 2016 annual meeting of stockholders attended that meeting.

Board Committees

The Board has three standing committees: an audit committee, a compensation committee, and a nominating and governance committee. The purpose, membership, and charter of each are described below.

Figure 6. Committee Membership

Audit committee. The purpose of the audit committee is to oversee the Company’s accounting and financial reporting processes and the audits of our financial statements, including the system of internal controls. As part of its responsibilities, the audit committee reviews and oversees the potential conflict of interest situations, transactions required to be disclosed pursuant to Item 404 of Regulation S-K of the SEC, and any other transaction involving an executive or Board member. A copy of the audit committee charter is available on the Investors section of our website at http://investor.lamresearch.com/corporate-governance.cfm.

The Board concluded that all audit committee members are non-employee directors who are independent in accordance with the Nasdaq listing standards and SEC rules for audit committee member independence and that each audit committee member is able to read and understand fundamental financial statements as required by the Nasdaq listing standards. The Board also determined that Messrs. Brandt and Cannon (both members of the committee) are each, and Messrs. Anstice, Newberry, and Talwalkar and Ms. Lego (members of the Board) each qualify as, an “audit committee financial expert” as defined in the SEC rules.

Compensation committee. The purpose of the compensation committee is to discharge certain responsibilities of the Board relating to executive compensation; to oversee incentive, equity-based plans, and other compensatory plans in which the Company’s executive officers and/or directors participate; and to produce an annual report on executive compensation for inclusion as required in the Company’s annual proxy statement. The compensation committee is authorized to perform the responsibilities of the committee referenced above and described in the charter. A copy of the compensation committee charter is available on the Investors section of our website at http://investor.lamresearch.com/corporate-governance.cfm.

The Board concluded that all members of the compensation committee are non-employee directors who are independent in accordance with Rule 16b-3 of the Exchange Act and the Nasdaq criteria for director and compensation committee member independence and who are outside directors for purposes of section 162(m) of the Code.

Nominating and governance committee. The purpose of the nominating and governance committee is to identify individuals qualified to serve as members of the Board of the Company, to recommend nominees for election as directors of the Company, to oversee self-evaluations of the Board’s performance, to develop and recommend corporate governance guidelines to the Board, and to provide oversight with respect to corporate governance. A copy of the nominating and governance committee charter is available on the Investors section of our website at http://investor.lamresearch.com/corporate-governance.cfm.

The Board concluded that all nominating and governance committee members are non-employee directors who are independent in accordance with the Nasdaq criteria for director independence.

The nominating and governance committee will consider for nomination persons properly nominated by stockholders in accordance with the Company’s bylaws and other procedures described below under “Voting and Meeting Information – Other Meeting Information – Stockholder-Initiated Proposals and Nominations for 2018 Annual Meeting.” Subject to then-applicable law, stockholder nominations for director will be evaluated by the Company’s nominating and governance committee in accordance with the same criteria as is applied to candidates identified by the nominating and governance committee or other sources.

Board’s Role and Engagement

General. The Board directs and oversees the management of the business and affairs of the Company. In this oversight role, the Board serves as the ultimate decision-making body of the Company, except for those matters reserved for the stockholders.

The Board and its committees have the primary responsibilities of:

Risk oversight. The Board is actively engaged in risk oversight. Management regularly reports to the Board on its risk assessments and risk mitigation strategies for the major risks of our business. Generally, the Board exercises its oversight responsibility directly; however, in specific cases, such responsibility has been delegated to committees of the Board. Committees that have been charged with risk oversight regularly report to the Board on those risk matters within their areas of responsibility. Risk oversight responsibility has been delegated to committees of the Board as set forth below.

Our director compensation is designed to attract and retain high-caliber directors and to align director interests with those of stockholders. Director compensation is reviewed and determined annually by the Board (in the case of Messrs. Newberry and Anstice, by the independent members of the Board), upon recommendation from the compensation committee. Non-employee director compensation (including the compensation of Mr. Newberry, who is currently our non-employee chairman) is described below. Mr. Anstice, whose compensation as CEO is described below under “Compensation Matters – Executive Compensation and Other Information – Compensation Discussion and Analysis,” does not receive additional compensation for his service on the Board.

Non-employee director compensation. Non-employee directors receive annual cash retainers and equity awards. The chairman of the Board, committee chairs, the lead independent director, and committee members receive additional cash retainers. Non-employee directors who join the Board or a committee midyear receive pro-rated cash retainers and equity awards, as applicable. Our non-employee director compensation program is based on service during the calendar year; however, SEC rules require us to report compensation in this proxy statement on a fiscal-year basis. Cash compensation paid to non-employee directors for the fiscal year ended June 25, 2017, together with the annual cash compensation program components in effect for calendar years 2016 and 2017, is shown in the table below.

Figure 7. Director Annual Retainers

Each non-employee director also receives an annual equity grant on the first Friday following the annual meeting with a targeted grant date value equal to $200,000 (the number of RSUs subject to the award is determined by dividing $200,000 by the closing price of a share of Company common stock as of the date of grant, rounded down to the nearest 10 shares). These grants generally vest on October 31 in the year following the grant and are subject to the terms and conditions of the Company’s 2015 Stock Incentive Plan, as amended, or the “2015 Plan,” and the applicable award agreements. These grants immediately vest in full: (1) if a non-employee director dies or becomes subject to a “disability” (as determined pursuant to the 2015 Plan), (2) upon the occurrence of a “Corporate Transaction” (as defined in the 2015 Plan), or (3) on the date of the annual meeting if the annual meeting during the year in which the award was expected to vest occurs prior to the vest date and the non-employee director is not re-elected or retires or resigns effective immediately prior to the annual meeting. Non-employee directors who

commence service after the annual award has been granted receive on the first Friday following the first regularly scheduled, quarterly Board meeting attended a pro-rated grant based on the number of regularly scheduled, quarterly Board meetings remaining in the year as of the effective date of the director’s appointment. The pro-rated grants are subject to the same vesting schedule, terms and conditions as the annual equity awards, except that if the award is granted on the first Friday following the regularly scheduled quarterly November Board meeting, the grant vests immediately.

On November 11, 2016, Dr. Tsai, who was appointed to the Board effective September 13, 2016, received a pro-rated grant of 510 RSUs for service during calendar year 2016 that vested immediately.

On November 11, 2016, each director other than Mr. Anstice and Dr. Koh, who was appointed a director on May 10, 2017, received a grant of 2,050 RSUs for service during calendar year 2017.

On May 12, 2017, Dr. Koh, who was appointed to the Board effective May 10, 2017, received a pro-rated grant of 1,000 RSUs for service during calendar year 2017.

Unless there is an acceleration event, these RSUs granted to each current director for service during calendar year 2017 will vest in full on October 31, 2017, subject to the director’s continued service on the Board.

Chairman compensation. Mr. Newberry, who served as vice-chairman from December 7, 2010 to November 1, 2012 and since such date has served as chairman, has a chairman’s agreement documenting his responsibilities, described above under “Governance Matters – Corporate Governance – Leadership Structure of the Board,” and compensation. Mr. Newberry entered into a chairman’s agreement with the Company commencing on January 1, 2017, and expiring on December 31, 2017, subject to the right of earlier termination in certain circumstances and a one-year extension upon mutual written agreement of the parties. The agreement provides that Mr. Newberry will serve as chairman (and not as an employee or officer) and in addition to his regular compensation as a non-employee director, he receives an additional cash retainer of $160,000 on the same date.

Mr. Newberry was eligible to participate through 2014 in the Company’s Elective Deferred Compensation Plan that is generally applicable to executives of the Company, subject to the general terms and conditions of such plan. He continues to maintain a balance in the plan until he no longer performs service for the Company as a director but is no longer eligible to defer any compensation into the plan.

The following table shows compensation for fiscal year 2017 for persons serving as directors during fiscal 2017 other than Mr. Anstice:

Figure 8. FY2017 Director Compensation

Other benefits. Any members of the Board enrolled in the Company’s health plans on or prior to December 31, 2012, can continue to participate after retirement from the Board in the Company’s Retiree Health Plans. The Board eliminated this benefit for any person who became a director after December 31, 2012. The most recent valuation of the Company’s accumulated post-retirement benefit obligation under Accounting Standards Codification 715, Compensation-Retirement Benefits, or “ASC 715,” as of June 25, 2017, for eligible former directors and the current directors who may become eligible is shown below. Factors affecting the amount of post-retirement benefit obligation include age at enrollment, age at retirement, coverage tier (e.g., single, plus spouse, plus family), interest rate, and length of service.

Figure 9. FY2017 Accumulated Post-Retirement Benefit Obligations

To understand our executive compensation program fully, we believe it is important to understand:

Our Business, Our Industry Environment, and Our Financial Performance

Lam Research has been an innovative supplier of wafer fabrication equipment and services to the semiconductor industry for more than 35 years. Our customer base includes leading semiconductor memory, foundry, and integrated device manufacturers that make products such as non-volatile memory (NVM), DRAM memory, and logic devices. We aim to increase our strategic relevance with our customers by contributing more to their continued success. Our core technical competency is integrating hardware, process,

materials, software, and process control enabling results on the wafer.

Our products and services are designed to help our customers build smaller, faster, and better performing devices that are used in a variety of electronic products, including mobile phones, personal computers, servers, wearables, automotive devices, storage devices, and networking equipment.

Semiconductor manufacturing, our customers’ business, involves the complete fabrication of multiple dies or integrated circuits on a wafer. This involves the repetition of a set of core processes and can require hundreds of individual steps. Fabricating these devices requires highly sophisticated process technologies to integrate an increasing array of new materials with precise control at the atomic scale. Along with meeting technical requirements, wafer processing equipment must deliver high productivity and be cost-effective.

Demand from the Cloud, Internet of Things (IoT), and other markets is driving the need for increasingly powerful and cost-efficient semiconductors. At the same time, there are growing technical challenges with traditional two-dimensional scaling. These trends are driving significant inflections in semiconductor manufacturing, such as the increasing importance of vertical scaling strategies like 3D architectures as well as multiple patterning to enable shrinks.

We believe we are in a strong position with our leadership and competency in deposition, etch, and single-wafer clean to facilitate some of the most significant innovations in semiconductor device manufacturing. Several factors create opportunity for sustainable differentiation for us: our focus on research and development, with a breadth of programs across sustaining engineering, product and process development, and concept and feasibility; our ability to effectively leverage cycles of learning from our broad installed base; and our collaborative focus with ecosystem partners.

Although we have a June fiscal year end, our executive compensation program is generally designed and oriented on a calendar-year basis to correspond with our calendar-year-based business planning. This CD&A generally reflects a calendar-year orientation rather than a fiscal-year orientation, as shown below. The Executive Compensation Tables at the end of this CD&A are based on our fiscal year, as required by SEC regulations.

Figure 12. Executive Compensation Calendar-Year Orientation

In calendar year 2016, demand for semiconductor equipment increased relative to calendar year 2015 as technology inflections led to higher investments. Against this backdrop, Lam delivered record financial performance.

Highlights for calendar year 2016:

In the first half of calendar year 2017, investments for wafer fabrication equipment spending have remained solid as customers transition to next-generation technology nodes, which are increasingly complex and more costly to produce.

Lam has continued to generate solid operating income and cash generation with revenues of $4.5 billion, and cash flows from operations of $1.2 billion earned from the March and June 2017 quarters combined.

Executive Compensation Philosophy and Program Design

Executive Compensation Philosophy

The philosophy of our compensation committee that guided this year’s awards and payout decisions is that our executive compensation program should:

Our compensation committee’s executive compensation objectives are to motivate:

Program Design

Our program design uses a mix of annual and long-term components, and a mix of cash and equity components. Our executive compensation program includes base salary, an annual incentive program, or “AIP,” and a long-term incentive program, or “LTIP,” as well as stock ownership guidelines and a compensation recovery policy. As illustrated below, our program design is weighted towards performance and stockholder value. The performance-based program components include AIP cash payouts and market-based equity and stock option awards under the LTIP.

For senior vice presidents and above, we also have stock ownership guidelines that foster a long-term orientation. See next paragraph for additional information.

Our stock ownership guidelines for our NEOs and certain other senior executives are shown below. The requirements are specified in the alternative of shares or dollars to allow for stock price volatility. Ownership levels as shown below must be achieved within five years of appointment to one of the below positions. Increased requirements due to promotions or

an increase in the ownership guideline must be achieved within five years of promotion or a change in the guidelines. At the end of fiscal year 2017, all NEOs were in compliance with our stock ownership guidelines or have a period of time remaining under the guidelines to meet the required ownership level.

Compensation Recovery, or “Clawback” Policy

Our executive officers covered by section 16 of the Exchange Act are subject to the Company’s compensation recovery, or “clawback,” policy. The clawback policy was adopted in August 2014 and will enable us to recover, within 36 months of the issuance of the original financial statements, the excess amount of cash incentive-based compensation issued starting in calendar year 2015 to officers covered by section 16 of the Exchange Act when a material restatement of financial results

is required. A covered individual’s fraud must have materially contributed to the need to issue restated financial statements in order for the clawback policy to apply to that individual. The recovery of compensation is not the exclusive remedy available in the event that the clawback policy is triggered.

Executive Compensation Highlights

Highlights of our executive compensation program are listed in Figure 4. Executive Compensation Highlights.

Role of the Compensation Committee

Our Board has delegated certain responsibilities to the compensation committee, or the “committee,” through a formal charter. The committee¹ oversees the compensation programs in which our chief executive officer and his direct executive and senior vice president reports participate. The independent members of our Board approve the compensation packages and payouts for our CEO. The CEO is not present for any decisions regarding his compensation packages and payouts.

Committee responsibilities include but are not limited to: reviewing and approving the Company’s executive compensation philosophy, objectives, and strategies; reviewing and approving the appropriate peer group companies for purposes of evaluating the Company’s compensation competitiveness; causing the Board to perform a periodic performance evaluation of the CEO; recommending to the independent members of the Board (as determined under both Nasdaq’s listing standards and section 162(m) of the Code) corporate goals and objectives under the Company’s compensation plans, compensation packages (e.g., annual base salary level, annual cash incentive award, long-term incentive award and any employment agreement, severance arrangement, change-in-control arrangement, equity grant, or special or supplemental benefits, and any material amendment to any of the foregoing) as applicable to the CEO, and compensation payouts for the CEO; annually reviewing with the CEO the performance of the Company’s other executive officers in light of the Company’s executive compensation goals and objectives and approving the compensation packages and compensation payouts for such individuals; reviewing and recommending for appropriate Board action all cash, equity-based and other compensation packages, and compensation payouts applicable to the chairman and other members of the Board; and reviewing, and approving where appropriate, equity-based compensation plans.

The committee is authorized to delegate such of its authority and responsibilities as the committee deems proper and consistent with legal requirements to members of the committee, any other committee of the Board and one or more officers of the Company in accordance with the provisions of the Delaware General Corporation Law. For additional information on the committee’s responsibilities and authorities, see “Governance Matters – Corporate Governance – Board Committees – Compensation Committee” above.

In order to carry out these responsibilities, the committee receives and reviews information, analysis and proposals prepared by our management and by the committee’s compensation consultant (see “Role of Committee Advisors” below).

Role of Committee Advisors

The committee is authorized to engage its own independent advisors to assist in carrying out its responsibilities. The committee has engaged the services of Compensia, Inc., or “Compensia,” a national compensation consulting firm, as the committee’s compensation consultant. Compensia provides the committee with independent and objective guidance regarding the amount and types of compensation for our chairman, non-employee directors, and executive officers and how these amounts and types of compensation compare to other companies’ compensation practices, as well as guidance on market trends, evolving regulatory requirements, compensation of our independent directors, peer group composition and other matters as requested by the committee.

Representatives of Compensia regularly attend committee meetings (including executive sessions without management present), communicate with the committee chair outside of meetings, and assist the committee with its consideration of performance metrics and goals. Compensia reports to the committee, not to management. At the committee’s request, Compensia meets with members of management to gather and discuss information that is relevant to advising the committee. The committee may replace Compensia or hire additional advisors at any time. Compensia has not provided any other services to the committee or to our management, and has received no compensation from us other than with respect to the services described above. The committee assessed the independence of Compensia pursuant to SEC rules and Nasdaq listing standards, including the following factors: (1) the absence of other services provided by it to the Company; (2) the fees paid to it by the Company as a percentage of its total revenue; (3) its policies and procedures to prevent conflicts of interest; (4) the absence of any business or personal relationships with committee members; (5) the fact that it does not own any Lam common stock; and (6) the absence of any business or personal relationships with our executive officers. The committee assessed this information and concluded that the work of Compensia had not raised any conflict of interest.

Role of Management

Our CEO, with support from our human resources and finance organizations, develops recommendations for the compensation of our other executive officers. Typically, these

recommendations cover base salaries, annual incentive program target award opportunities, long-term incentive program target award opportunities, and the criteria upon which these award opportunities may be earned, as well as actual payout amounts under the annual and long-term incentive programs.

The committee considers the CEO’s recommendations within the context of competitive compensation data, the Company’s compensation philosophy and objectives, current business conditions, the advice of Compensia, and any other factors it considers relevant. At the request of the committee, our chairman also provides input to the committee.

Our CEO attends committee meetings at the request of the committee, but leaves the meeting for any deliberations related to and decisions regarding his own compensation, when the committee meets in executive session, and at any other time requested by the committee.

Peer Group Practices and Survey Data

In establishing the total compensation levels of our executive officers as well as the mix and weighting of individual compensation elements, the committee monitors compensation data from a group of comparably sized companies in the technology industry, or the “Peer Group,” which may differ from peer groups used by stockholder advisory firms. The committee selects the companies constituting our Peer Group based on their comparability to our lines of business and industry, annual revenue, and market capitalization, and our belief that we are likely to compete with them for executive talent. Our Peer Group is focused on U.S. based, public semiconductor, semiconductor equipment and materials companies, and similarly sized high-technology equipment and hardware companies with a global presence and a significant investment in research and development. The table below summarizes how the Peer Group companies compare to the Company:

Figure 15. 2017 Peer Group Revenue and Market Capitalization

Based on these criteria, the Peer Group and targets may be modified from time to time. Our Peer Group was reviewed in August 2016 for calendar year 2017 compensation decisions and based on the criteria identified above, two companies were added to the peer group (Micron Technology and

Skyworks Solutions) and three companies (Avago Technologies, Freescale Semiconductor, and Marvel Technology Group Ltd.) were removed. Our Peer Group consists of the companies listed as follows.

Figure 16. CY2017 Peer Group Companies

We derive revenue, market capitalization, and NEO compensation data from public filings made by our Peer Group companies with the SEC and other publicly available sources. Radford Technology Survey data may be used to supplement compensation data from public filings as needed. The committee reviews compensation practices and selected data on base salary, bonus targets, total cash compensation, equity awards, and total compensation drawn from the Peer Group companies and/or the Radford Technology Survey as a reference to help ensure compensation packages are consistent with market norms.

Base pay levels for each executive officer are generally set with reference to market competitive levels and in reflection of each officer’s skills, experiences, and performance. Variable pay target award opportunities and total direct compensation for each executive officer are generally designed to deliver market competitive compensation for the achievement of stretch goals with downside risk for underperforming and upside reward for success. For those executive officers who are new to their roles, compensation arrangements may be designed to deliver below market compensation for a period of time. However, the committee does not “target” pay at any specific percentile. Rather, individual pay positioning depends on a variety of factors, such as prior job performance, job scope and responsibilities, skill set, prior experience, time in position, internal comparisons of pay levels for similar skill levels or positions, our goals to attract and retain executive talent, Company performance, and general market conditions.

Assessment of Compensation Risk

Management, with the assistance of Compensia, the committee’s independent compensation consultant, conducted a compensation risk assessment in 2017 and concluded that the Company’s current employee compensation programs are not reasonably likely to have a material adverse effect on the Company’s business.

2016 Say on Pay Voting Results; Company Response

We evaluate our executive compensation program annually. Among other things, we consider the outcome of our most recent Say on Pay vote and input we receive from our stockholders. In 2016, our stockholders approved our 2016

advisory vote on executive compensation, with 98.32% of the votes cast in favor of the advisory proposal. We believe that our most recent Say on Pay vote signifies our stockholders’ support of our executive compensation program and practices. We did not make any material changes to our programs and practices in fiscal year 2017.

This section describes the components of our executive compensation program. It also describes, for each component, the payouts to our NEOs for calendar year 2016 and the forward-looking actions taken with respect to our NEOs in calendar year 2017.

Base Salary

We believe the purpose of base salary is to provide competitive compensation to attract and retain top talent and to provide compensation to employees, including our NEOs, with a fixed and fair amount of compensation for the jobs they perform. Accordingly, we seek to ensure that our base salary levels are competitive in reference to Peer Group practice and market survey data. Adjustments to base salary are generally considered by the committee each year in February.

For calendar years 2017 and 2016, base salaries for NEOs were determined by the committee in February of each year and became effective on March 1 or the first day of the pay period that included March 1 (if earlier), based on the factors described above. The following base salary adjustments for 2017 were made to remain competitive against our Peer Group and reflect performance as follows: Mr. Archer’s base salary was increased by 5%, Mr. Anstice’s was increased by 3.1%, Mr. Bettinger’s and Ms. O’Dowd’s were increased by 3%, and Dr. Gottscho’s was increased by 2%. The base salaries of the NEOs for calendar years 2017 and 2016 are as follows:

Figure 17. NEO Annual Base Salaries

Annual Incentive Program

Design

Our annual incentive program is designed to provide annual, performance-based compensation that: (1) is based on the achievement of pre-set annual financial, strategic, and operational objectives aligned with outstanding performance, and (2) will allow us to attract and retain top talent, while maintaining cost-effectiveness to the Company. The committee establishes individual target award opportunities for each NEO as a percentage of base salary. Specific target award opportunities are determined based on job scope and responsibilities, as well as an assessment of Peer Group data. Awards have a maximum payment amount defined as a multiple of the target award opportunity. The maximum award for 2016 and 2017 was set at 2.25 times target, consistent with prior years.

Annual incentive program components

Annual incentive program components, each of which plays a role in determining actual payments made, include:

The Funding Factor is set by the committee to create a maximum payout amount from which annual incentive program payouts may be made. The committee may exercise negative (but not positive) discretion against the Funding Factor result, and generally the entire funded amount is not paid out. Achievement of a minimum level of performance against the Funding Factor goals is required to fund any program payments. In February 2016, for calendar year 2016, the committee set non-GAAP operating income as a percentage of revenue as the metric for the Funding Factor, with the following goals:

The committee selected non-GAAP operating income as a percentage of revenue because it believes that operating income as a percentage of revenue is the performance metric that best reflects core operating results.² Non-GAAP operating income is considered useful to investors for analyzing business trends and comparing performance to prior periods. By excluding certain costs and expenses that are not indicative of core results, non-GAAP results are more useful for analyzing business trends over multiple periods.

As a guide for using negative discretion against the Funding Factor results and for making payout decisions, the committee primarily tracks the results of the following two components that are weighted equally in making payout decisions, and against which discretion may be applied in a positive or negative direction, provided the Funding Factor result is not exceeded:

The specific metrics and goals, and their relative weightings, for the Corporate Performance Factor are determined by the committee based upon the recommendation of our CEO, and the Individual Performance Factors are determined by our CEO, or in the case of the CEO, by the committee.

The metrics and goals for the Corporate and Individual Performance Factors are set annually. Goals are set depending on the business environment, ensuring that they

are stretch goals regardless of changes in the business environment. Accordingly, as business conditions improve, goals are set to require better performance, and as business conditions deteriorate, goals are set to require stretch performance under more difficult conditions.

We believe that, over time, outstanding business results create stockholder value. Consistent with this belief, multiple performance-based metrics (non-GAAP operating income, product market share, and strategic operational, and organizational metrics) are established for our NEOs as part of the Corporate and Individual Performance Factors.

We believe the metrics and goals set under this program, together with the exercise of discretion by the committee as described above, have been effective to motivate our NEOs and the organizations they lead and to achieve pay-for-performance results.

Calendar year 2016 annual incentive program parameters and payout decisions

In February 2016, the committee set the calendar year 2016 target award opportunity and established the metrics and goals for the Funding Factor, the metrics and annual goals for the Corporate Performance Factor, and the metrics and goals for the Individual Performance Factors for each NEO were established. In February 2017, the committee considered the actual results under these factors and made payout decisions for the calendar year 2016 program, all as described below.

2016 Annual Incentive Program Target Award Opportunities. The annual incentive program target award opportunities for calendar year 2016 for each NEO were as set forth in Figure 19 below in accordance with the principles set forth above under “Executive Compensation Governance and Procedures – Peer Group Practices and Survey Data.”

2016 Annual Incentive Program Corporate Performance Factor. In February 2016, the committee set non-GAAP operating income as a percentage of revenue as the metric for the calendar year 2016 Corporate Performance Factor, and set:

These goals were designed to be stretch goals. Actual non-GAAP operating income as a percentage of revenue was 22.9% for calendar year 2016. This performance resulted in a total Corporate Performance Factor for calendar year 2016 of 1.29.

2016 Annual Incentive Program Organization/Individual Performance Factor. For 2016, the organization-specific performance metrics and goals for each NEO’s Individual Performance Factor were set on an annual basis, and were designed to be stretch goals. The Individual Performance Factor for Mr. Anstice for calendar year 2016 was based on the average of the Individual Performance Factors of all the

executive and senior vice presidents reporting to him. For all other NEOs, their respective Individual Performance Factors were based on market share and/or strategic, operational, and organizational performance goals specific to the organizations they managed, as described in more detail below.

The accomplishments of actual individual performance against the established goals described below during 2016 were considered.

In consideration of the CEO’s assessment of each individual’s achievements and the teamwork demonstrated to deliver the overall strong company performance in 2016, the committee exercised discretion such that each NEO received an Individual Performance Factor of 1.29 (equal to the Corporate Performance Factor) for the 2016 calendar year.

2016 Annual Incentive Program Payout Decisions. In February 2017, in light of the Funding Factor results and based on the above results and decisions, the committee approved the following payouts for the calendar year 2016 annual incentive program for each NEO, which were substantially less than the maximum payout available under the Funding Factor:

Calendar year 2017 annual incentive program parameters

In February 2017, the committee set the target award opportunity for each NEO as a percentage of base salary, and consistent with prior years set a cap on payments equal to 2.25 times the target award opportunity. The target award opportunity for each NEO is shown below.

Figure 20. CY2017 Annual Incentive Program Target Award Opportunities

The committee also approved the annual metric for the Funding Factor and the Corporate Performance Factor as non-GAAP operating income as a percentage of revenue, and set the annual goals for the Funding Factor and the Corporate Performance Factor. Consistent with the program design, the Corporate Performance Factor goal is more difficult to achieve than the Funding Factor goal. Individual Performance Factor metrics and goals were also established for each NEO. These include strategic and operational performance goals specific to individuals and their business organization. As a result, each NEO has multiple performance metrics and goals under this program. All Corporate and Individual Performance Factor goals were designed to be stretch goals.

Long-Term Incentive Program

Design

Our long-term incentive program, or “LTIP,” is designed to attract and retain top talent, provide competitive levels of compensation, align pay with achievement of business objectives and with stock performance over a multi-year period, reward our NEOs for outstanding Company performance, and create stockholder value over the long term.

Under the current long-term incentive program, at the beginning of each multi-year performance period, target award opportunities (expressed as a U.S. dollar value) and performance metrics are established for the program. Of the total target award opportunity, 50% is awarded in Market-based PRSUs, and the remaining 50% is awarded in a combination of stock options and service-based RSUs with at least 10% of the award in each of these two vehicles. The specific percentage of service-based RSUs and stock options are reviewed annually to determine whether service-based RSUs or stock options are the more efficient form of equity for the majority of the award based on criteria such as the current business environment and the potential value to motivate and retain the executives. We consider performance-based RSUs and stock options as performance-based, but do not classify service-based RSUs as performance-based. This means that if options constitute 10% of the total target award opportunity, the long-term incentive program will be 60% performance-based. If options constitute 40% of the total target award opportunity, the long-term incentive program will be 90% performance-based.

Figure 22. Market-based PRSU Vesting Summary

Target Award Opportunity

Under the long-term incentive program, the committee sets a target award opportunity for each participant based on the NEO’s position and responsibilities and an assessment of competitive compensation data. The target award opportunities for each participant are expressed in a U.S. dollar value. The target amounts for each NEO under the program cycles affecting fiscal year 2017 are as follows:

Figure 23. LTIP Target Award Opportunities

Calendar Year 2014/2016 LTIP Award Parameters and Payouts

On February 18, 2014, the committee granted to each NEO as part of the calendar year 2014/2016 long-term incentive program, or “2014/2016 LTIP Awards,” Market-based PRSUs, and service-based RSUs and stock options with a total target award opportunity shown below. The service-based RSUs and stock options vested over three years, one-third on each anniversary of the grant date. The Market-based PRSU’s cliff vested three years from the grant date.

Figure 24. 2014/2016 LTIP Awards

In February 2017, the committee determined the payouts for the calendar year 2014/2016 LTIP Awards of Market-based PRSUs. The number of shares represented by the Market-based PRSUs earned over the performance period was based on our stock price performance compared to the market price performance of the SOX index.

Based on the above formula and Market-based PRSU Vesting Summary set forth in Figures 21-22, the Company’s stock price performance over the three-year performance period was equal to 110.32% and performance of the SOX index (based on market price) over the same three-year performance period was equal to 76.27%. While Lam’s stock price outperformed the SOX index by 34.05%, which would have resulted in a performance payout of 168% to target under our Market-based PRSU program, the actual number of shares paid represented by the Market-based PRSUs was limited to the maximum payout of 150% of the target number of Market-based PRSUs granted to each NEO. Based on such

results, the committee made the following payouts to each NEO for the 2014/2016 LTIP Award of Market-based PRSUs.

Calendar Year 2017 LTIP Awards

Calendar year 2017 decisions for the 2017/2019 long-term incentive program. On March 1, 2017, the committee made a grant under the 2017/2019 long-term incentive program, of Market-based PRSUs, stock options, and service-based RSUs on the terms set forth in Figure 21 with a combined value equal to the NEO’s total target award opportunity, as shown in the following table.

Figure 26. 2017/2019 LTIP Awards

Employment/Change in Control Arrangements

The Company enters into employment/change in control agreements to help attract and retain our NEOs and believes that these agreements facilitate a smooth transaction and transition planning in connection with change in control events. Effective January 2015, the Company entered into new three-year term employment agreements with Messrs. Anstice, Archer, and Bettinger and Dr. Gottscho, and a new change in control agreement with Ms. O’Dowd. The employment agreements generally provide for designated

payments in the event of an involuntary termination of employment, death or disability, as such terms are defined in the applicable agreements. The employment agreements, and also the change in control agreements, generally provide for designated payments in the case of a change in control when coupled with an involuntary termination (i.e., a double trigger is required before payment is made due to a change in control), as such terms are defined in the applicable agreements.

For additional information about these arrangements and detail about post-termination payments under these arrangements, see the “Potential Payments upon Termination or Change in Control” section below.

Other Benefits Not Available to All Employees

Elective Deferred Compensation Plan

The Company maintains an elective deferred compensation plan that allows eligible employees (including all the NEOs) to voluntarily defer receipt of all or a portion of base salary and certain incentive compensation payments until a date or dates elected by the participating employee. This allows the employee to defer taxes on designated compensation amounts. In addition, the Company provides a limited Company contribution to the plan for all eligible employees.

Supplemental Health and Welfare

We provide certain health and welfare benefits not generally available to other employees, including the payment of premiums for supplemental long-term disability insurance and Company-provided coverage in the amount of $1 million for both life and accidental death and dismemberment insurance for all NEOs. Until January 1, 2013, the Company also provided an executive medical, dental, and vision reimbursement program that reimbursed NEOs’ cost of medical, dental, and vision expenses in excess of the regular employee plans through the end of 2012.

We also provide post-retirement medical and dental insurance coverage for eligible former executive officers under our Retiree Health Plans, subject to certain eligibility requirements. The program was closed to executive officers who joined the Company or became executive officers through promotion effective on or after January 1, 2013. We have an independent actuarial valuation of post-retirement benefits for eligible NEOs conducted annually in accordance with generally accepted accounting principles. The most recent valuation was conducted in June 2016 and reflected the following retirement benefit obligation for the NEOs:

Figure 27. NEO Post-Retirement Benefit Obligations

Deductibility of Executive Compensation

Section 162(m) of the Internal Revenue Code of 1986, as amended, or the “Code,” imposes limitations on the deductibility for federal income tax purposes of compensation in excess of $1 million paid to our chief executive officer, and any of our three other most highly compensated executive officers (other than our chief financial officer) in a single tax year. Generally, compensation in excess of $1 million may only be deducted if it is qualified as “performance-based compensation” within the meaning of the Code.

The committee monitors the application of section 162(m) and the associated Treasury regulations and considers the advisability of qualifying our executive compensation for deductibility of such compensation. The committee’s policy is to qualify our executive compensation for deductibility under applicable tax laws to the extent practicable and where the committee believes it is in the best interests of the Company and the Company’s stockholders.

When we design our executive compensation programs, we take into account whether a particular form of compensation will qualify as “performance-based” for purposes of section 162(m).

To facilitate the deductibility of compensation payments under section 162(m):

The annual program awards to our NEOs are generally administrated under the AIP and intended to qualify for deductibility under section 162(m) to the extent practicable.

Consistent with the EIP or SIP, and the regulations under section 162(m), compensation income realized upon the exercise of stock options generally will be deductible because the awards are granted by a committee whose members are outside directors and the other conditions of the 162(m) are satisfied. However, compensation associated with RSUs may not be deductible unless vesting is based on specific performance goals (such as with the Market-based PRSUs) and the other conditions of the EIP or SIP (as applicable) are satisfied. Therefore, compensation income realized upon the vesting of service-based RSUs or upon the vesting of equity awards not meeting the conditions required by the EIP or SIP are not deductible to the Company to the extent that the 162(m) compensation threshold is exceeded.

Taxation of “Parachute” Payments

Sections 280G and 4999 of the Code provide that “disqualified individuals” within the meaning of the Code (which generally includes certain officers, directors and employees of the Company) may be subject to additional tax if they receive payments or benefits in connection with a change in control of the Company that exceed certain prescribed limits. The Company or its successor may also forfeit a deduction on the amounts subject to this additional tax.

We did not provide any of our executive officers, any director, or any other service provider with a “gross-up” or other reimbursement payment for any tax liability that the individual might owe as a result of the application of sections 280G or 4999 during fiscal year 2017, and we have not agreed and are not otherwise obligated to provide any individual with such a “gross-up” or other reimbursement as a result of the application of sections 280G and 4999.

Internal Revenue Code Section 409A

Section 409A of the Code imposes significant additional taxes on an executive officer, director, or service provider that

receives non-compliant “deferred compensation” that is within the scope of section 409A. Among other things, section 409A potentially applies to the cash awards under the LTIP, the Elective Deferred Compensation Plan, certain equity awards, and severance arrangements.

To assist our employees in avoiding additional taxes under section 409A, we have structured the LTIP, the Elective Deferred Compensation Plan, and our equity awards in a manner intended to qualify them for exclusion from, or compliance with, section 409A.

Accounting for Stock-Based Compensation

We follow Financial Accounting Standards Board Accounting Standards Codification Topic 718, or “ASC 718,” for accounting for our stock options and other stock-based awards. ASC 718 requires companies to calculate the grant date “fair value” of their stock option grants and other equity awards using a variety of assumptions. This calculation is performed for accounting purposes. ASC 718 also requires companies to recognize the compensation cost of stock option grants and other stock-based awards in their income statements over the period that an employee is required to render service in exchange for the option or other equity award.

Compensation Committee Report

The compensation committee has reviewed and discussed with management the Compensation Discussion and Analysis

required by Item 402(b) of SEC Regulation S-K. Based on this review and discussion, the compensation committee has recommended to the Board that the Compensation Discussion and Analysis be included in this proxy statement and the Company’s Annual Report on Form 10-K.

This Compensation Committee Report shall not be deemed “filed” with the SEC for purposes of federal securities law, and it shall not, under any circumstances, be incorporated by reference into any of the Company’s past or future SEC filings. The report shall not be deemed soliciting material.
