PROXY STATEMENT
FOR 2016 ANNUAL MEETING OF STOCKHOLDERS

QUESTIONS AND ANSWERS ABOUT THE 2016 ANNUAL MEETING AND
PROCEDURAL MATTERS

We expect to mail the Notice of Internet Availability of Proxy Materials (the “Notice”) on or about April 29, 2016. Copies of our proxy materials and 2015 Annual Report are available at www.envisionreports.com/FTNT.

The 2016 Annual Meeting will be held at Fortinet’s principal executive offices, located at 899 Kifer Road, Sunnyvale, CA 94086. The telephone number at that location is (408) 235-7700. As a stockholder, you are invited to attend the 2016 Annual Meeting and are requested to vote on the proposals described in this proxy statement.

Choosing to receive future proxy materials by email will save us the cost of printing and mailing documents to you and will reduce the impact of our annual meetings on the environment. If you choose to receive future proxy materials by email, you will receive an email next year with instructions containing a link to those materials and a link to the proxy voting site.

TABLE OF CONTENTS

If your shares are held by a brokerage account or by another nominee, you are considered the “beneficial owner” of shares held in “street name,” and the Notice is being forwarded to you together with voting instructions on behalf of your broker, trustee or nominee. As the beneficial owner, you have the right to direct your broker, trustee or nominee how to vote, and you are also invited to attend the 2016 Annual Meeting. Your broker, trustee or nominee has enclosed or provided voting instructions for you to use in directing the broker, trustee or nominee how to vote your shares. Because a beneficial owner is not the stockholder of record, you may not vote these shares in person at the 2016 Annual Meeting unless you obtain a “legal proxy” from the broker, trustee or nominee that holds your shares, giving you the right to vote the shares at the 2016 Annual Meeting. If you hold your shares through a broker and do not provide your broker with specific voting instructions, under the rules that govern brokers in such circumstances, your broker will have the discretion to vote such shares on routine matters but not on non-routine matters. Even though we are a NASDAQ-listed company, the New York Stock Exchange (“NYSE”) rules govern how a broker licensed by the NYSE can vote shares it holds on behalf of stockholders of NASDAQ-listed companies. As a result:

Because the proposals to be acted upon at the 2016 Annual Meeting include both routine and non-routine matters, if you do not give voting instructions to your broker, trustee or nominee, your broker, trustee or nominee may either (1) vote your shares on routine matters or (2) leave your shares unvoted.

A broker “non-vote” occurs when your broker, trustee or nominee does not vote on a particular proposal because the broker, trustee or nominee does not have discretionary voting power with respect to that item and has not received voting instructions from you as the beneficial owner.

TABLE OF CONTENTS

By mail — If you are a stockholder of record, you may vote by submitting a proxy card — please refer to the voting instructions in the Notice or below. If you hold shares beneficially in street name, you may vote by submitting voting instructions to your broker, trustee or nominee — please refer to the voting instructions provided to you by your broker, trustee or nominee.

By Internet — Stockholders of record of Fortinet common stock with Internet access may submit proxies by following the “Vote by Internet” instructions described in the Notice until 11:59 p.m., Eastern time, on June 16, 2016 or by following the instructions at www.envisionreports.com/FTNT. Most Fortinet stockholders who hold shares beneficially in street name may vote by accessing the web site specified in the voting instructions provided by their brokers, trustees or nominees. Please check the voting instructions for Internet voting availability.

By telephone — Depending on how your shares are held, you may be able to vote by telephone. If this option is available to you, you will have received information with the Notice or the voting instruction card provided by your broker, trustee or nominee explaining this procedure.

Under Delaware law, abstentions and broker non-votes are counted as present and entitled to vote for purposes of determining whether a quorum is present at the 2016 Annual Meeting. However, as discussed above, under “What is the difference between holding shares as a stockholder of record or as a beneficial owner?” brokers have limited discretionary authority to vote shares that are beneficially owned and, therefore, are not entitled to vote on non-routine matters in the absence of voting instructions from the beneficial owner of such shares.

The affirmative vote of a majority of the shares of our common stock that are present in person or represented by proxy at the 2016 Annual Meeting and entitled to vote is required to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm (Proposal Two) and approve the advisory resolution on executive compensation (Proposal Three).

TABLE OF CONTENTS

Abstentions are deemed to be shares present or represented by proxy and entitled to vote. Abstentions have no effect on Proposal One and the same effect as a vote against Proposals Two and Three. Broker non-votes are not deemed to be shares entitled to vote on and will have no effect on Proposals One and Three. Brokers have discretionary authority to vote shares that are beneficially owned on Proposal Two. If a broker chooses not to vote shares for or against Proposal Two, it would have the same effect as an abstention.

All shares entitled to vote and represented by properly submitted proxies received prior to the 2016 Annual Meeting (and not revoked) will be voted at the 2016 Annual Meeting in accordance with the instructions indicated by such proxy. If no instructions are indicated on such proxy, the shares represented by that proxy will be voted as recommended by the Board of Directors.

If you are the stockholder of record, you may change your vote (1) by granting a new proxy bearing a later date (which automatically revokes the earlier proxy) using any of the methods described above (and until the applicable deadline for each method), (2) by providing a written notice of revocation to Fortinet’s Corporate Secretary at Fortinet, Inc., 899 Kifer Road, Sunnyvale, CA 94086 prior to your shares being voted, or (3) by attending the 2016 Annual Meeting and voting in person. Attendance at the meeting will not cause your previously granted proxy to be revoked unless you specifically so request.

If you are a beneficial owner of shares held in street name, you may change your vote (1) by submitting new voting instructions to your broker, trustee or nominee or (2) if you have obtained a legal proxy from the broker, trustee or nominee that holds your shares giving you the right to vote your shares, by attending the 2016 Annual Meeting and voting in person.

If a broker, trustee or nominee beneficially holds your shares in street name and you wish to attend the 2016 Annual Meeting and vote in person, you must obtain a legal proxy from the broker, trustee or nominee that holds your shares giving you the right to vote the shares. If you are a beneficial owner and you wish to attend the 2016 Annual Meeting but do not intend to vote in person or revoke your prior voting instructions, you do not need to obtain a legal proxy but you will need to bring proof of ownership and photo identification.

TABLE OF CONTENTS

If you choose to access the proxy materials and/or vote over the Internet, you are responsible for Internet access charges you may incur. If you choose to vote by telephone, you are responsible for telephone charges you may incur.

For inclusion in Fortinet’s proxy materials — Stockholders may present proper proposals for inclusion in Fortinet’s proxy statement and for consideration at the next annual meeting of stockholders by submitting their proposals in writing to Fortinet’s Corporate Secretary in a timely manner. In order to be included in the proxy statement for the 2017 Annual Meeting, stockholder proposals must be received by Fortinet’s Corporate Secretary no later than December 30, 2016, and must otherwise comply with the requirements of Rule 14a-8 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

To be brought before the annual meeting — In addition, Fortinet’s bylaws establish an advance notice procedure for stockholders who wish to present certain matters before an annual meeting of stockholders. In general, nominations for the election of directors may be made (1) by or at the direction of the Board of Directors, or (2) by a stockholder who has delivered written notice to Fortinet’s Secretary within the Notice Period (as defined below) and who was a stockholder at the time of such notice and as of the record date. The notice must contain specified information about the nominees and about the stockholder proposing such nominations.

TABLE OF CONTENTS

Fortinet’s bylaws also provide that the only business that may be conducted at an annual meeting is business that is (1) properly brought before the meeting pursuant to Fortinet’s proxy materials with respect to such meeting, (2) properly brought before the meeting by or at the direction of the Board of Directors, or (3) properly brought before the meeting by a stockholder who has delivered written notice to Fortinet’s Corporate Secretary at its principal executive offices within the Notice Period (as defined below) and who was a stockholder at the time of such notice and as of the record date. The notice must contain specified information about the matters to be brought before such meeting and about the stockholder proposing such matters.

The “Notice Period” is defined as that period not less than 45 days nor more than 75 days prior to the one year anniversary of the date on which Fortinet mailed its proxy materials or the Notice (whichever is earlier) to stockholders in connection with the preceding year’s annual meeting of stockholders. As a result, the Notice Period for the 2017 Annual Meeting will start on February 13, 2017 and end on March 15, 2017.

If a stockholder who has notified Fortinet of his or her intention to present a proposal at an annual meeting does not appear to present his or her proposal at such meeting, Fortinet need not present the proposal for vote at such meeting.

A copy of the full text of the bylaw provisions discussed above may be obtained by writing to Fortinet’s Corporate Secretary at our principal executive offices or by accessing Fortinet’s filings on the SEC’s website at www.sec.gov. All notices of proposals by stockholders, whether or not included in Fortinet’s proxy materials, should be sent to Fortinet’s Corporate Secretary at our principal executive offices.

TABLE OF CONTENTS

PROPOSAL ONE
 
ELECTION OF DIRECTORS

General

Our Board of Directors currently consists of seven members who are divided into three classes with staggered three-year terms. Each director holds office until that director’s successor is duly elected and qualified. Our bylaws permit our Board of Directors to establish by resolution the authorized number of directors, and seven directors are currently authorized. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one third of the directors.

Nominees

Two candidates have been nominated for election as Class I directors at the 2016 Annual Meeting for a three-year term expiring in 2019. Upon recommendation of the Nominating and Corporate Governance Committee, the Board of Directors has nominated Ming Hsieh and Christopher B. Paisley for election as Class I directors. Biographical information about each of the nominees is contained in the following section. A discussion of the qualifications, attributes and skills of each nominee that led our Board of Directors and the Nominating and Corporate Governance Committee to the conclusion that he should serve as a director has been added following each of the director and nominee biographies.

Each person nominated for election has agreed to serve if elected, and management has no reason to believe that any nominee will be unavailable to serve. In the event any nominee is unable or declines to serve as a director at the time of the 2016 Annual Meeting, the proxies will be voted for any nominee who may be proposed by the Nominating and Corporate Governance Committee and designated by the present Board of Directors to fill the vacancy.

If you sign your proxy card or voting instruction card or vote by telephone or over the Internet but do not give instructions with respect to the voting of directors, your shares will be voted for the two persons recommended by our Board of Directors. If you wish to give specific instructions with respect to the voting of directors, you may do so by indicating your instructions on your proxy or voting instruction card or when you vote by telephone or over the Internet. If you do not give voting instructions to your broker, your broker will leave your shares unvoted on this matter.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE
“FOR” THE ELECTION OF MING HSIEH AND CHRISTOPHER B. PAISLEY.

General

The Audit Committee has selected Deloitte & Touche LLP as Fortinet’s independent registered public accounting firm to audit the financial statements of Fortinet for the fiscal year ending December 31, 2016, which will include an audit of the effectiveness of Fortinet’s internal control over financial reporting. A representative of Deloitte & Touche LLP is expected to be present at the 2016 Annual Meeting, will have the opportunity to make a statement if he or she desires to do so, and is expected to be available to respond to appropriate questions.

If the appointment is not ratified, the Audit Committee will consider whether it should select other independent auditors. Even if the appointment is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm as Fortinet’s independent auditors at any time during the year if the Audit Committee determines that such a change would be in Fortinet’s and its stockholders’ best interests.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE RATIFICATION OF THE
APPOINTMENT OF DELOITTE & TOUCHE LLP AS FORTINET’S INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2016.

TABLE OF CONTENTS

PROPOSAL THREE
 
ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

As required by Schedule 14A of the Securities Exchange Act and the corresponding SEC rules, Fortinet is seeking stockholder approval, on an advisory or non-binding basis, of the compensation of our named executive officers as disclosed in accordance with the SEC’s rules in the “Executive Compensation” section of this proxy statement. This proposal, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to express their views on our named executive officers’ compensation as a whole. This vote is not intended to address any specific item of compensation or any specific named executive officer but rather the overall compensation of all of our named executive officers and the compensation philosophy, policies and practices described in this proxy statement.

The say-on-pay vote is advisory, and therefore not binding on Fortinet, the Compensation Committee or our Board of Directors. Following the 2016 Annual Meeting, the next such non-binding advisory vote to approve our named executive officers’ compensation as a whole is scheduled to occur at the 2017 Annual Meeting.

Our Board of Directors and our Compensation Committee value the opinions of our stockholders and the say-on-pay vote provides information to us regarding investor sentiment about our executive compensation philosophy, policies and practices, which the Compensation Committee will be able to consider when determining executive compensation for the remainder of the current fiscal year and beyond. To the extent there is any significant vote against the named executive officer compensation as disclosed in this proxy statement, we will consider our stockholders’ concerns, and the Compensation Committee will evaluate whether any actions are necessary to address those concerns. We believe that the information we have provided in the “Executive Compensation” section of this proxy statement, and in particular the information discussed in “Executive Compensation — Compensation Discussion and Analysis,” demonstrates that our executive compensation program was designed appropriately and is working to ensure management’s interests are aligned with our stockholders’ interests. Accordingly, we ask our stockholders to vote “FOR” the following resolution at the 2016 Annual Meeting:

“RESOLVED, that Fortinet’s stockholders approve, on an advisory basis, the compensation of the named executive officers, as disclosed in Fortinet’s proxy statement for the 2016 Annual Meeting pursuant to the Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, the compensation tables and narrative discussion, and the other related disclosure.”

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THIS PROPOSAL.

Fortinet will disclose on its website any amendment to the Code of Business Conduct and Ethics, as well as any waivers of the Code of Business Conduct and Ethics, that are required to be disclosed by the rules of the SEC or The NASDAQ Stock Market LLC (“NASDAQ”).

Corporate Governance Guidelines

We have adopted Corporate Governance Guidelines to establish the corporate governance policies which provide a structure within which our Board of Directors and management can effectively pursue Fortinet’s objectives for the benefit of our stockholders. Fortinet’s Corporate Governance Guidelines are available on Fortinet’s website at investor.fortinet.com/governance.cfm.

Majority Voting Standard for Director Elections and Director Resignation Policy

Our Bylaws provide for a majority voting standard for uncontested elections of directors and require that stockholder director nominations include a written statement as to whether the nominee intends to tender his or her irrevocable resignation upon his or her election or re-election. The majority voting standard provides that in uncontested director elections, a director nominee will be elected only if the number of votes cast FOR the nominee exceeds the number of votes cast AGAINST the nominee. In addition our Corporate Governance Guidelines address, among other provisions, the “holdover” director situation under the Delaware General Corporation Law (pursuant to which a director remains on the board of directors until his or her successor is elected and qualified), by requiring each incumbent nominee to submit an irrevocable contingent resignation letter. Such resignation becomes effective only upon (x) such nominee’s failure to receive the requisite number of votes for re-election at any future meeting at which such person would face re-election and (y) our Board of Directors’ acceptance of such resignation. If the nominee does not receive more votes cast FOR his election than AGAINST his election, our Nominating and Corporate Governance Committee will make a recommendation to our Board of Directors as to whether to accept or reject the resignation, or whether other action should be taken. The Board of Directors will act on the Nominating and Corporate Governance Committee’s recommendation and publicly disclose its decision and the rationale behind it within 90 days from the date of the certification of the election results.

Director Independence

Our Board of Directors has determined that, with the exception of Messrs. Ken Xie and Michael Xie, who are employees of Fortinet, all of the current members of the Board of Directors and nominees for director are “independent directors” as that term is defined in NASDAQ’s listing standards.

Board Meetings and Committees

During fiscal 2015, the Board of Directors held six meetings. Each director attended at least 75% of the aggregate of all meetings of the Board of Directors and all meetings held by all committees of the Board of Directors on which he or she served during the past fiscal year. The Board of Directors has three standing committees: an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee.

Audit Committee

The Audit Committee, which has been established in accordance with Section 3(a)(58)(A) of the Exchange Act, is currently comprised of Messrs. Hsieh and Paisley and Ms. Sim, each of whom is “independent” as such term is defined for audit committee members by the listing standards of NASDAQ. Mr. Paisley is the Chairman of the Audit Committee. The Board of Directors has determined that Mr. Paisley is an “audit committee financial expert” as defined in the rules of the SEC.

TABLE OF CONTENTS

The Audit Committee is responsible for, among other things:

The Audit Committee held nine meetings during fiscal 2015. The Audit Committee has adopted a written charter approved by the Board of Directors, which is available on Fortinet’s website at investor.fortinet.com/governance.cfm.

The Audit Committee Report is included in this proxy statement on page 41.

Compensation Committee

Our Compensation Committee is currently comprised of Messrs. Hsieh, Neukom and Paisley, each of whom qualifies as an independent director under the listing standards of NASDAQ. Mr. Neukom is currently the Chairman of our Compensation Committee.

Our Compensation Committee is responsible for, among other things:

See “Executive Compensation — Compensation Discussion and Analysis” and “Executive Compensation — Compensation of Directors” for a description of Fortinet’s processes and procedures for the consideration and determination of executive officer and director compensation.

The Compensation Committee held four meetings during fiscal 2015. The Compensation Committee has adopted a written charter approved by the Board of Directors, which is available on Fortinet’s website at investor.fortinet.com/governance.cfm.

The Compensation Committee Report is included in this proxy statement on page 27.

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance committee is currently comprised of Messrs. Hsieh, Locke and Neukom, each of whom qualifies as an independent director under the listing standards of NASDAQ. Mr. Locke is the Chairman of the Nominating and Corporate Governance Committee.

Our Nominating and Corporate Governance Committee is responsible for, among other things:

TABLE OF CONTENTS

The Nominating and Corporate Governance Committee will consider recommendations of candidates for the Board of Directors submitted by stockholders of Fortinet; see “Process for Recommending Candidates for Election to the Board of Directors” below.

The Nominating and Corporate Governance Committee held three meetings during fiscal 2015. The Nominating and Corporate Governance Committee has adopted a written charter approved by the Board of Directors, which is available on Fortinet’s website at investor.fortinet.com/governance.cfm.

Compensation Committee Interlocks and Insider Participation

Messrs. Hsieh, Neukom and Paisley served as members of the Compensation Committee during fiscal 2015. In addition, Chenming Hu served as a member of the Compensation Committee during fiscal 2015 until our annual meeting in June 2015. None of the members of our Compensation Committee during fiscal 2015 is or has in the past served as an officer or employee of our company. None of our executive officers currently serves, or in the past year has served, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving on our Board of Directors or Compensation Committee during fiscal 2015.

Board Leadership Structure

Our Corporate Governance Guidelines provide the Board of Directors with flexibility to select the appropriate leadership structure depending on what the Board of Directors determines is in the company’s best interests at a given time. In making leadership structure determinations, the Board of Directors considers many factors, including the specific needs of the business and what is in the best interests of our stockholders. A copy of our Corporate Governance Guidelines is available on our website at investor.fortinet.com/governance.cfm.

Mr. Paisley currently serves as our Lead Independent Director and Mr. Ken Xie serves as our Chairman and Chief Executive Officer. In addition to the duties of all members of the Board of Directors, Mr. Paisley’s principal responsibilities as the Lead Independent Director of the Board of Directors are to preside over executive sessions of the Board of Directors, review and comment on the agenda for meetings of the Board of Directors in consultation with the Chairman and Chief Executive Officer and other members of the Board of Directors, act as principal liaison between the independent directors and the Chairman and Chief Executive Officer on sensitive issues, raise issues with management on behalf of the independent directors when appropriate and assess the quality, quantity and timeliness of the flow of information from management that is necessary for the independent directors to effectively and responsibly perform their duties.

Our Board of Directors believes that the current leadership structure provides an appropriate balance between strong leadership from our Chairman and Chief Executive Officer and oversight by independent directors. In particular, this structure capitalizes on the expertise and experience of Messrs. Ken Xie and Paisley as it permits Mr. Xie to serve as a bridge between the Board of Directors and management, helping both to act with a common purpose, and providing critical leadership for carrying out our strategy and confronting challenges, while Mr. Paisley ensures independence of the Board of Directors from management and as Lead Independent Director can call and chair meetings of the independent directors separate and apart from the Chairman. The Board of Directors also believes that there may be other advantages to having a Lead Independent Director for matters such as communications and relations between the Board of Directors, the Chief Executive Officer, and other senior management, and in assisting the Board of Directors in reaching consensus on particular strategies and policies. Messrs. Ken Xie and Michael Xie, as the only two management directors, do not participate in sessions of non-management directors, and non-management directors meet regularly in executive session without management.

TABLE OF CONTENTS

Board’s Role in Risk Oversight

The Board of Directors oversees an enterprise-wide approach to risk management, designed to support the achievement of organizational objectives, including strategic objectives, to improve long-term organizational performance and to enhance stockholder value. A fundamental part of risk management is not only understanding the most significant risks a company faces and what steps management is taking to manage those risks but also understanding what level of risk is appropriate for the company. The involvement of the full Board of Directors in reviewing Fortinet’s business is an integral aspect of its assessment of management’s tolerance for risk and also its determination of what constitutes an appropriate level of risk for Fortinet.

While the Board of Directors has the ultimate oversight responsibility for the risk management process, various committees of the Board of Directors also have responsibility for risk management. The charter of the Audit Committee provides that one of the Audit Committee’s responsibilities is oversight of certain compliance matters. In addition, in setting compensation, the Compensation Committee strives to create incentives that encourage a level of risk-taking consistent with Fortinet’s business strategy and to encourage a focus on building long-term value at Fortinet.

At periodic meetings of the Board of Directors and its committees and in other meetings and discussions, management reports to and seeks guidance from the Board of Directors and its committees with respect to the most significant risks that could affect our business, such as legal risks and financial, tax and audit related risks. In addition, management provides the Audit Committee periodic reports on Fortinet’s compliance programs and efforts, investment policy and practices.

Process for Recommending Candidates for Election to the Board of Directors

The Nominating and Corporate Governance Committee is responsible for, among other things, determining the criteria for membership to the Board of Directors and recommending candidates for election to the Board of Directors. It is the policy of the Nominating and Corporate Governance Committee to consider recommendations for candidates to the Board of Directors from stockholders. Stockholder recommendations for candidates to the Board of Directors must be directed in writing to Fortinet, Inc., 899 Kifer Road, Sunnyvale, CA 94086, Attention: Corporate Secretary, and must include the candidate’s name, home and business contact information, detailed biographical data and qualifications, information regarding any relationships between the candidate and Fortinet within the last three years and evidence of the nominating person’s ownership of Fortinet’s common stock. Such recommendations must also include a statement from the recommending stockholder in support of the candidate, particularly within the context of the criteria for membership on the Board of Directors, including issues of character, judgment, diversity, including whether the person is a current or former CEO or CFO of a public company or the head of a division of a large international organization, independence, expertise, corporate experience, length of service, other commitments and the like, personal references, and an indication of the candidate’s willingness to serve. There are no differences in the manner by which the Nominating and Corporate Governance Committee evaluates nominees for director based on whether the nominee is recommended by a stockholder or the Board of Directors.

The Nominating and Corporate Governance Committee’s criteria and process for evaluating and identifying the candidates that it recommends to the full Board of Directors for selection as director nominees are as follows:

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

The following discussion and analysis provides information about the 2015 compensation arrangements for each individual who served as one of our executive officers during 2015, who were as follows:

We refer to these individuals as “named executive officers” in this proxy statement. This compensation discussion and analysis should be read together with the compensation tables and related disclosures that follow it. This discussion contains forward looking statements that are based on our current plans, considerations, expectations and determinations regarding future compensation programs. Actual compensation programs that we adopt may differ materially from currently planned programs as summarized in this discussion.

    Overview

We compete with many other technology companies in seeking to attract and retain a skilled workforce. We also seek to keep our employees motivated. To meet these challenges, we designed our compensation programs to attract, retain and motivate our named executive officers to enhance stockholder value by:

Because our compensation programs are designed to align our executives’ compensation to our operating, financial and stock price performance, you should consider our executive compensation decisions in the context of these areas of performance during fiscal 2015, including:

    Role of the Compensation Committee in Executive Compensation Decisions

The Compensation Committee of our Board of Directors has overall responsibility for approving the compensation of our named executive officers. Members of the Compensation Committee are appointed by our Board of Directors. See “Corporate Governance — Board Meetings and Committees — Compensation Committee” for more detail about the responsibilities and procedures of the Compensation Committee.

TABLE OF CONTENTS

    Role of Compensation Consultant

In determining executive compensation, the Compensation Committee of our Board of Directors has considered, at least annually, an analysis from an independent third-party compensation consultant and reserves the right to consider analyses from more than one compensation consultant.

For fiscal 2015, the Compensation Committee engaged Compensia to provide a competitive market assessment of Fortinet’s executive compensation program and to report on the results of such assessment. The compensation consultant has provided market and peer company compensation data as one consideration for the Compensation Committee as discussed in more detail below under “— Determining the Amount of Elements of Executives’ Compensation in 2015.” Based on consideration of the various factors set forth in the SEC rules and NASDAQ listing standards, the Compensation Committee does not believe that its relationship with Compensia and the work of Compensia on behalf of the Compensation Committee has raised any conflict of interest.

    Role of Executives in Executive Compensation Decisions

Our Compensation Committee generally seeks input from our Chief Executive Officer, Mr. Ken Xie, when discussing the performance of and compensation levels for named executive officers other than for himself and Mr. Michael Xie. Neither Mr. Ken Xie nor any of our other named executive officers participates in deliberations relating to their own compensation, and Messrs. Ken Xie and Michael Xie do not participate in deliberations related to each other’s compensation.

Our stockholders will have the opportunity again at this year’s Annual Meeting to vote on our named executive officer compensation through the stockholder advisory vote on executive compensation (commonly known as a “say-on-pay” vote) included as Proposal Three in this proxy statement. At each of our past two annual meetings of stockholders, over 98% of the stockholder votes cast were cast in favor of our named executive officer compensation. The Compensation Committee considers input from stockholders and the outcome of our annual say-on-pay votes when making future executive compensation decisions and, to the extent there is any significant vote against the named executive officer compensation as disclosed in this proxy statement, the Compensation Committee will consider our stockholders’ concerns and will evaluate whether any actions are appropriate to address those concerns. Since the 2015 stockholder vote on executive compensation occurred after the Compensation Committee had established all of the compensation elements for 2015, our Compensation Committee would only take into consideration last year’s stockholder vote in establishing executive compensation in 2016. We encourage you to review this “Executive Compensation” section, together with the compensation tables that follow, prior to casting your advisory vote on the “say-on-pay” proposal.

Elements of Our Compensation Program

The four key elements of our compensation package for named executive officers are base pay, equity-based awards, variable pay and our benefits programs. As a total package, we design our compensation program to enable us to attract and retain talent who add to Fortinet’s long-term value. The individual elements of Fortinet’s compensation program are designed to satisfy this larger goal in specific ways as described below. For a detailed discussion of the amounts awarded to our named executive officers during 2015, see “— Determining the Amount of Elements of Executives’ Compensation in 2015 ” below.

Base Pay.  We establish base pay that is both reasonable and competitive in relation to the surveyed market of similar companies in the technology industry. We monitor competitive base pay levels at least annually and make adjustments to base pay as appropriate. In general, a named executive officer’s base pay level should reflect that individual’s overall sustained performance and contribution over time. We design base pay to provide the ongoing reward for each named executive officer’s work and contribution and to be competitive in attracting or retaining the executive. Any increases in base pay are provided generally on an annual basis.

Equity-Based Awards.  We design our equity programs to be both reasonable and competitive in relation to the market. Stock options, restricted stock units (“RSUs”), which represent a right to receive shares of our common stock upon vesting over time, and performance stock units (“PSUs”), which are similar to RSUs but for which payout is based on the satisfaction of performance criteria determined by our Compensation

TABLE OF CONTENTS

Committee, which are designed to reflect and reward sustained performance over time, as reflected in improved overall company value. As described in more detail below, we design equity-based compensation to help retain talent over a period of time and to provide named executive officers with a long-term reward that aligns their interests with those of our stockholders. A number of factors are considered when determining the size of equity grants, including peer group data, named executive officer performance, retention value, the value of unvested equity awards already held by the named executive officer, and a review of the named executive officer’s overall compensation package, which takes into account our approach to base pay and variable pay. Initial grants upon hire are generally designed to attract experienced executives with established records of success and help retain them over the long term. Subsequent grants to named executive officers are designed to help retain and incentivize named executive officers.

The Compensation Committee granted refresh awards of RSUs and PSUs to named executive officers in January 2015. The Compensation Committee grants PSUs in order to create a stronger and more visible link between executive pay and the company’s stock price performance; to further align our executives’ interests with those of our stockholders; to mitigate the impact of the volatility of the broader stock market on our equity programs; to better incentivize and retain our senior executives; and to move to a long-term incentive program that is more consistent with practices at peer companies. The PSUs granted in 2015 vest up to 50% at the end of a two-year service period ending in February 2017, and up to the remaining 50%, plus any unvested shares from the two-year period, at the end of a three-year service period ending in February 2018, based on the company’s relative stock price performance over those respective periods compared to the performance of the NASDAQ Composite Index, with the “Award Multiplier” below applied to the amount of the original grant to vest:

Fortinet Stock Price Performance Relative to NASDAQ Composite Index		Award Multiplier
+25% points or greater			150	%
+12.5% points			125	%
0% points			100	%
-16.7% points			50	%
-33.3% points or less			0	%

Stock price performance is measured using the average share price of the applicable stock during the final 90 trading days of the two- or three-year performance period divided by the average share price during the 90 trading days ending on the trading day prior to the first day of the two- or three-year performance period, including the value attributable to reinvestment of dividends, if any. The Compensation Committee believes that RSUs and PSUs serve to align executive pay with stockholder value because the ultimate compensation opportunity correlates with the company’s stock price over an extended period of time and, in the case of the PSUs, with Fortinet’s performance compared to that of the broader stock market, represented by the NASDAQ Composite Index.

Although the Compensation Committee has decided to grant RSUs and PSUs based on the structure above, it retains the ability to change its approach to equity grants as a form of long-term equity incentive at its discretion.

Variable Pay.  Rewarding performance through variable pay is an important element of named executive officer compensation. We design our variable pay programs to be both reasonable and competitive in relation to the market. We consider adjusting our variable pay programs as appropriate for our named executive officers. Our senior management incentive bonus program is designed to motivate our named executive officers to achieve goals and to align payouts with actual results. The variable pay incentives are based on a formulaic assessment of our financial performance and an assessment of each individual’s performance. The Compensation Committee has the discretion to increase or decrease a payout under the variable pay programs at any time in the event that it determines that circumstances warrant adjustment. A key factor in this evaluation is our executive “peer review” process, in which our broader executive team reviews the performance of certain other executives, including certain named executive officers, on a quarterly basis, and their confidential feedback is reviewed by our Compensation Committee when considering individual variable pay incentives. We believe the executive peer review motivates executive officers to work together in a productive fashion.

TABLE OF CONTENTS

Benefits Programs.  We provide our named executive officers the following benefits: employee retirement; health and welfare benefits, such as our 401(k) retirement plan; group health insurance plans; and life, disability and accidental death insurance plans. Our named executive officers generally receive the same benefits as those provided to our other U.S. employees and do not receive additional perquisites. Our employee benefits programs are typically established and adjusted by our human resources department with approval, as necessary, from senior management and are consistent with the competitive practices of companies similar to us.

Determining the Amount of Elements of Executives’ Compensation in 2015

Overview.  In analyzing elements of our compensation program in 2015, the Compensation Committee engaged Compensia to provide an assessment of the compensation we offer to our named executive officers. The Compensation Committee also engaged Compensia for the limited purpose of gaining access to the compensation data that Compensia compiles for use in setting compensation for employees other than named executive officers. With respect to Compensia’s engagement in 2015, Compensia considered the compensation practices of the technology companies listed below, each of which had annual revenues ranging from approximately $288 million to $847 million, market capitalization generally ranging from $2.0 billion to $6.5 billion, and between 669 and 5,735 employees.

3D Systems Corporation		FireEye, Inc.
ANSYS, Inc.		Informatica Corporation
Aruba Networks, Inc.		IPG Photonics Corporation
Aspen Technology, Inc.		NetSuite Inc.
Check Point Software Technologies Ltd.		Palo Alto Networks, Inc.
CommVault Systems, Inc.		Solera Holdings Inc.
Concur Technologies, Inc.		The Ultimate Software Group, Inc.
CoStar Group Inc.		Verint Systems Inc.
FactSet Research Systems Inc.		VeriSign, Inc.

Base Pay.  As part of our annual performance review process and review of named executive officers’ compensation, early each year the Compensation Committee assesses the performance of the named executive officers, considering factors such as company performance, department performance, and individual performance, including the named executive officer’s expertise, position, past contributions to Fortinet and potential future contributions to Fortinet. Largely as a result of this assessment and taking into account reasonable annual base pay increase practices, the Compensation Committee considered whether and how much to adjust the base pay of the named executive officers.

Taking into consideration performance and reasonable merit increases, in January 2015, the Compensation Committee raised the annual base pay of Mr. Ken Xie by 12.6% to $425,000, Mr. Michael Xie by 12% to $375,000, Mr. Del Matto by 3% to $391,400 and Mr. Whittle by 5% to $344,532. After these increases, the base pay of Mr. Ken Xie was below Compensia’s 25^th percentile of market data, Mr. Michael Xie’s was at Compensia’s 75^th percentile of market data, Mr. Del Matto’s was near Compensia’s 55^th percentile of market data and Mr. Whittle’s was near Compensia’s 40^th percentile of market data.

Equity-Based Awards.  In granting RSUs and PSUs to our named executive officers in 2015, the Compensation Committee exercised its judgment and considered, among other things, the role and contribution of the named executive officer and the value of unvested stock options, RSUs and PSUs already held by the executive.

In January 2015, the Compensation Committee approved refresh awards of 40,000 RSUs for each of Mr. Ken Xie and Mr. Michael Xie and 30,000 RSUs for each of Mr. Del Matto and Mr. Whittle. Each of these RSUs was granted in accordance with Fortinet’s Equity Award Grant Policy discussed in “— Timing of Equity Awards” below, and vests over four years with 25% vesting approximately one year from the date of grant and the remainder vesting quarterly thereafter.

TABLE OF CONTENTS

Also in January 2015, the Compensation Committee approved refresh awards of 40,000 PSUs for Mr. Ken Xie, 30,000 PSUs for Mr. Michael Xie and 20,000 PSUs for each of Mr. Del Matto and Mr. Whittle. Each of these PSUs vests 50% at the end of a two-year service period and up to the remaining 50%, plus any unvested from the two-year period, at the end of a three-year service period with a multiplier based on Fortinet’s relative stock price performance over those respective periods compared to the performance of the NASDAQ Composite Index, as described in more detail under “— Elements of Our Compensation Program — Equity Based Awards” above.

Variable Pay.  We determine the executive’s actual level of variable compensation in accordance with the terms of the variable pay programs. In developing the framework, we seek to set total cash compensation (base salary plus variable pay) to meet our goal of ensuring that our cash compensation levels are competitive and to enable us to retain and motivate our named executive officers.

In 2015, our variable pay programs for named executive officers fell under the Fortinet, Inc. Bonus Plan (the “Bonus Program”), with the Compensation Committee establishing, each year, a more detailed incentive bonus program within the parameters of our Bonus Program. In 2015, the Compensation Committee based the Bonus Program funding on achievement of revenue and operating income targets, as set forth in more detail below, with 75% of the bonus pool funding based on revenue achievement and 25% based on operating income achievement. We weight the Bonus Program funding more heavily toward achieving revenue over operating income targets because we believe that, at this stage, a focus on growing revenues will help drive our long-term success and result in greater opportunity for profit in the future and enhanced stockholder value. We believe it is important for our executives to monitor expenses closely as well, so we also base a portion of the bonus pool funding on the operating income target. Operating income for purposes of the Bonus Program is not calculated in accordance with U.S. generally accepted accounting principles and is defined as net income plus income taxes, stock-based compensation, interest income and foreign exchange currency gains or losses.

A minimum percentage of the revenue and operating income target must be met before funding can occur. For 2015, with respect to Messrs. Ken Xie and Michael Xie, the minimum percentage of both the revenue target and the operating income target was 95%. Once the threshold performance target is realized, the funding for Messrs. Ken Xie and Michael Xie increases on a graduated basis for each of the revenue portion and the operating income portion as follows:

Revenue Performance		Funding Amount
95% – 100%		70% funding of the revenue-based portion for performance at 95% and 6% funding for every additional 1% of performance between 95% and 100%
100% – 150%		0.8% funding for every additional 1% of performance between 100% and 150%

Operating Income Performance		Funding Amount
95% – 100%		70% funding of the operating income-based portion for performance at 95% and 6% funding for every additional 1% of performance between 95% and 100%
100% – 150%		0.8% funding for every additional 1% of performance between 100% and 150%

For example, for the revenue portion for Messrs. Ken Xie and Michael Xie:

TABLE OF CONTENTS

For 2015, with respect to Messrs. Del Matto and Whittle, the minimum percentage of the revenue target was 90% and the minimum percentage of the operating income target was 85%. Once the threshold performance target is realized, the funding for Messrs. Del Matto and Whittle increases on a graduated basis for each of the revenue portion and the operating income portion as follows:

Revenue Performance		Funding Amount
90% – 100%		40% funding of the revenue-based portion for performance at 90% and 6% funding for every additional 1% of performance between 90% and 100%
100% – 150%		0.8% funding for every additional 1% of performance between 100% and 150%

Operating Income Performance		Funding Amount
85% – 90%		8% funding of the operating income-based portion for every additional 1% of performance over 85%
90% – 100%		6% funding for every additional 1% of performance between 90% and 100%
100% – 150%		0.8% funding for every additional 1% of performance between 100% and 150%

For example, for the revenue portion for Messrs. Del Matto and Whittle:

Bonuses are calculated and awarded quarterly. Individual target bonuses under the Bonus Program are expressed as a percentage of the named executive officer’s base salary for 100% goal achievement. During 2015, our chief executive officer made bonus recommendations to the Compensation Committee for Messrs. Del Matto and Whittle, taking into consideration company achievement versus the financial targets discussed below and peer review data. The Compensation Committee in turn gave final approval after discussing the recommendations. The Compensation Committee approved bonuses for Messrs. Ken Xie and Michael Xie based upon the same criteria under the Bonus Program. The compensation framework of variable pay for our named executive officers was approximately based on a market 50^th percentile target.

For 2015, the Compensation Committee approved bonus targets of 100% of base salary for Mr. Ken Xie, 65% of base salary for Mr. Del Matto and 50% of base salary for Messrs. Michael Xie and Whittle. In addition, for 2015, Mr. Whittle was eligible for up to an additional 10% bonus for his strategic alliances and corporate development responsibilities. See “— 2015 Summary Compensation Table” below.

TABLE OF CONTENTS

As noted above, the Bonus Program is based on internal revenue and operating income performance targets set at the beginning of the year. The targets were set at levels determined to be challenging and requiring substantial effort on the part of senior management. For 2015, we achieved between 97% and 137% of our quarterly and annual operating income targets and we achieved between 100% and 104% of our quarterly and annual revenue targets. We paid bonuses to our senior management for 2015 based on achievement of these corporate goals and the peer reviews as discussed above. The charts below set forth our internal revenue and operating income performance targets compared to the revenue and operating income actually achieved, and indicates the percentages of target revenue actually achieved.

Benefits Programs.  In 2015, our named executive officers received the same employee benefits as our other U.S.-based employees. We design our employee benefits programs to be both cost-effective and competitive in relation to the market as well as compliant with applicable laws and practices. We adjust our benefits programs as needed based upon regular monitoring of applicable laws and practices and the overall market.

    Severance and Change of Control Agreements

In February 2016, we entered into Amended and Restated Change of Control Severance Agreements with each of Messrs. Ken Xie, Michael Xie, Del Matto and Whittle. The amendments were entered into to clarify the prior Change of Control Severance Agreements and did not reflect substantive changes. The Amended and Restated Change of Control Severance Agreements provide for payments and benefits upon termination of

their employment in specified circumstances. These arrangements (including potential payments and terms) are discussed in more detail in the “— Potential Payments Upon Termination or Change of Control” section below. We believe that these severance agreements help us from a retention standpoint, and they are particularly necessary in an industry such as ours, where there has been market consolidation. We believe that entering into these agreements helps the named executive officers maintain continued focus and dedication to their assigned duties to maximize stockholder value. The terms of these agreements were determined after review by the Compensation Committee of our retention goals for each named executive officer, as well as analysis of market data, similar agreements established by our peer group, and applicable law.

    Timing of Equity Awards

The Compensation Committee granted both refresh RSUs and refresh PSUs to executives in January 2015. The Board of Directors and Compensation Committee reserve the right, however, to grant refresh RSUs and PSUs, or other equity awards at other times during the year, and to grant more or fewer than two refresh grants per year. With respect to newly hired employees, our practice is typically to make stock grants at the first quarterly meeting of the Compensation Committee following such employee’s hire date.

Pursuant to our Equity Award Grant Policy, equity awards are granted effective as of the date that is the tenth trading day on the NASDAQ Global Market following the date of our next quarterly earnings announcement following the meetings of our Compensation Committee or Board of Directors when such equity awards were approved.

    Performance-Based Compensation Recovery Policy

The Compensation Committee has adopted a compensation recovery policy that allows us to recover or “clawback” performance-based cash compensation from certain employees who participate in the Bonus Program in the event of a material restatement of our financial results. Under the policy, if the material restatement would result in any performance-based cash compensation paid under the Bonus Program during the three years preceding the restatement to have been lower had it been calculated based on such restated results, we may recover the amounts in excess of what would have been paid under the restatement, from any participant who received such performance-based cash compensation who is determined to have engaged in intentional or unlawful misconduct that materially contributed to the need for such restatement. Our Board of Directors (or a committee designated by the Board of Directors) has the sole authority to enforce this policy, and it is limited by applicable law.

    Effect of Accounting and Tax Treatment on Compensation Decisions

In the review and establishment of our compensation programs, we consider the anticipated accounting and tax implications to us and our executives. In this regard, we use RSUs and PSUs, and reserve the right to use other forms of equity, as additional forms of equity compensation incentives in response to changes in the accounting treatment of equity awards and taking into consideration potential impact on dilution and competitive practices. While we consider the applicable accounting and tax treatment, these factors alone are not determinative, and we also consider the cash and non-cash impact of the programs and whether a program is consistent with our overall compensation philosophy and objectives.

Section 162(m) of the Internal Revenue Code of 1986, as amended (“Code”) imposes limits on the amount of compensation that a public company may deduct in any one year for the compensation of the chief executive officer and other highly compensated executive officers, unless specific and detailed criteria are satisfied. Performance-based compensation (including stock options), as defined in the Code, is fully deductible if the programs are approved by stockholders and meet other requirements. We have determined that we will not seek to limit executive compensation so that it is deductible under Section 162(m). However, from time to time, we may choose to structure our compensation programs to satisfy the requirements of Section 162(m). We seek to maintain flexibility in designing a comprehensive plan for our executives that promotes our corporate goals and therefore our Compensation Committee has not adopted a policy requiring all compensation to be deductible. To that end, our Board of Directors previously adopted, and our stockholders previously approved, the Fortinet, Inc. Cash and Equity Incentive Plan to permit cash bonuses and certain equity compensation to be considered “performance-based compensation” within the meaning of Section 162(m) of the Code and therefore fully deductible by us for federal income tax purposes.

Potential Payments Upon Termination or Change of Control

    Termination or Change of Control Arrangements

Ken Xie.  On February 4, 2016, we entered into an Amended and Restated Change of Control Severance Agreement with Ken Xie, our Chief Executive Officer, under which he may receive certain benefits upon certain terminations of employment, provided that he has provided us with an executed release of claims and subject to non-solicitation and non-competition for a period of twelve months. The amendment was entered into to clarify Mr. Ken Xie’s prior Change of Control Severance Agreement and did not reflect substantive changes. The term of Mr. Ken Xie’s Amended and Restated Change of Control Severance Agreement expires on August 7, 2019.

This agreement provides that, if Mr. Ken Xie’s employment is terminated without Cause (as defined below), or if he terminates his employment with us for Good Reason (as defined below), prior to, or absent, a Change of Control (as defined below) or after twelve months following a Change of Control, he will be entitled to a severance payment in an amount equal to twelve months of his then-current base salary and twelve months of medical, dental, and/or vision benefits for him and/or his eligible dependents. If Mr. Ken Xie is terminated without Cause, or if he terminates his employment with us for Good Reason, within one

TABLE OF CONTENTS

year following a Change of Control, in addition to receiving twelve months of base salary (as in effect immediately prior to the Change of Control or his termination, whichever is greater) and twelve months of medical, dental, and/or vision benefits for him and/or his eligible dependents, Mr. Ken Xie’s unvested equity awards will immediately vest as of his termination date. The awards will remain exercisable, to the extent applicable, following the termination for the period prescribed in the respective stock plan and agreement for each award. In the event any payment to Mr. Ken Xie is subject to the excise tax imposed by Section 4999 of the Code (as a result of a payment being classified as a parachute payment under Section 280G of the Code), he will be entitled to receive such payment as would entitle him to receive the greatest after-tax benefit of either the full payment or a lesser payment which would result in no portion of such severance benefits being subject to excise tax.

Michael Xie.  On February 4, 2016, we entered into an Amended and Restated Change of Control Severance Agreement with Michael Xie, our President and Chief Technology Officer, under which he may receive certain benefits upon certain terminations of employment, provided that he has provided us with an executed release of claims and subject to non-solicitation and non-competition for a period of twelve months. The amendment was entered into to clarify Mr. Michael Xie’s prior Change of Control Severance Agreement and did not reflect substantive changes. The term of Mr. Michael Xie’s Amended and Restated Change of Control Severance Agreement expires on August 7, 2019.

This agreement provides that, if Mr. Michael Xie’s employment is terminated without Cause, or if he terminates his employment with us for Good Reason, prior to, or absent, a Change of Control or after twelve months following a Change of Control, he will be entitled to a severance payment and/or benefits as determined by us in our sole discretion. If he is terminated without Cause, or if he terminates his employment with us for Good Reason, within one year following a Change of Control, he will receive a severance payment equal to six months of his base salary (as in effect immediately prior to the Change of Control or his termination, whichever is greater), twelve months of medical, dental, and/or vision benefits for him and/or his eligible dependents, and the unvested portion of his equity awards will immediately vest as of his termination date. The awards will remain exercisable, to the extent applicable, following the termination for the period prescribed in the respective stock plan and agreement for each award. In the event any payment to Mr. Michael Xie is subject to the excise tax imposed by Section 4999 of the Code (as a result of a payment being classified as a parachute payment under Section 280G of the Code), he will be entitled to receive such payment as would entitle him to receive the greatest after-tax benefit of either the full payment or a lesser payment which would result in no portion of such severance benefits being subject to excise tax.

Andrew Del Matto.  On February 4, 2016, we entered into an Amended and Restated Change of Control Severance Agreement with Andrew Del Matto, our Chief Financial Officer, under which he may receive certain benefits upon certain terminations of employment, provided that he has provided us with an executed release of claims and subject to non-solicitation and non-competition for a period of twenty-four months. The amendment was entered into to clarify Mr. Del Matto’s prior Change of Control Severance Agreement and did not reflect substantive changes. The term of Mr. Del Matto’s Change of Control Severance Agreement terminates on December 17, 2018.

This agreement provides that, if Mr. Del Matto’s employment is terminated without Cause, or if he terminates his employment with us for Good Reason, prior to, or absent, a Change of Control or after twelve months following a Change of Control, he will be entitled to a severance payment equal to nine months of base salary (as in effect immediately prior to his termination), nine months of medical, dental and/or vision benefits for him and/or his eligible dependents and his unvested equity awards will immediately vest as to the awards that would have vested over the next nine months and such accelerated awards become exercisable in full, and our right of repurchase or reacquisition with respect to such awards will lapse. If Mr. Del Matto is terminated without Cause, or if he terminates his employment with us for Good Reason, within one year following a Change of Control, he will be entitled to a severance payment equal to twelve months of base salary (as in effect immediately prior to the Change of Control or his termination, whichever is greater), twelve months of medical, dental and/or vision benefits for him and/or his eligible dependents and his unvested equity awards will immediately vest as of his termination date. The awards will remain exercisable, to the extent applicable, following the termination for the period prescribed in the respective stock plan and agreement for each award. In the event any payment to Mr. Del Matto is subject to

the excise tax imposed by Section 4999 of the Code (as a result of a payment being classified as a parachute payment under Section 280G of the Code), he will be entitled to receive such payment as would entitle him to receive the greatest after-tax benefit of either the full payment or a lesser payment which would result in no portion of such severance benefits being subject to excise tax.

John Whittle.  On February 4, 2016, we entered into an Amended and Restated Change of Control Severance Agreement with John Whittle, our Vice President of Corporate Development, General Counsel and Corporate Secretary, under which he may receive certain benefits upon certain terminations of employment, provided that he has provided us with an executed release of claims and subject to non-solicitation and non-competition for a period of twelve months. The amendment was entered into to clarify Mr. Whittle’s prior Change of Control Severance Agreement and did not reflect substantive changes. The term of Mr. Whittle’s Amended and Restated Change of Control Severance Agreement expires on August 7, 2019.

This agreement provides that, if Mr. Whittle’s employment is terminated without Cause, or if he terminates his employment with us for Good Reason, prior to, or absent, a Change of Control or after twelve months following a Change of Control, he will be entitled to a severance payment equal to twelve months of base salary (as in effect immediately prior to his termination) and his unvested equity awards will immediately vest as to the awards that would have vested over the next twelve months and such accelerated awards become exercisable in full, and our right of repurchase or reacquisition with respect to such awards will lapse. If Mr. Whittle is terminated without Cause, or if he terminates his employment with us for Good Reason, within one year following a Change of Control, then in addition to receiving twelve months base salary (as in effect immediately prior to the Change of Control or his termination, whichever is greater), he will receive twelve months of medical, dental and/or vision benefits for him and/or his eligible dependents and all of his unvested equity awards immediately vest as of his termination date. The awards will remain exercisable, to the extent applicable, following the termination for the period prescribed in the respective stock plan and agreement for each award. In the event any payment to Mr. Whittle is subject to the excise tax imposed by Section 4999 of the Code (as a result of a payment being classified as a parachute payment under Section 280G of the Code), he will be entitled to receive such payment as would entitle him to receive the greatest after-tax benefit of either the full payment or a lesser payment which would result in no portion of such severance benefits being subject to excise tax.

For the purpose of our Change of Control Severance Agreements with the above-mentioned executives:

Notwithstanding the foregoing, a transaction that does not constitute a change of control event under Treasury Regulation 1.409A-3(i)(5)(v) or (vii) shall not be considered a Change of Control.

TABLE OF CONTENTS

The executive may not resign for Good Reason without first providing us with written notice of the acts or omissions constituting the grounds for “Good Reason” within 90 days of the initial existence of the grounds for Good Reason and a reasonable cure period of not less than 30 days following the date of such notice.

    Estimated Payments Upon Termination or Change in Control

The following table provides information concerning the estimated payments and benefits that would be provided in the circumstances described above for each of the named executive officers. Except where otherwise noted, payments and benefits are estimated assuming that the triggering event took place on the last business day of fiscal 2015 (December 31, 2015), and the price per share of Fortinet’s common stock is the closing price on the NASDAQ Global Market as of that date ($31.17). There can be no assurance that a triggering event would produce the same or similar results as those estimated below if such event occurs on any other date or at any other price, of if any other assumption used to estimate potential payments and benefits is not correct. Due to the number of factors that affect the nature and amount of any potential payments or benefits, any actual payments and benefits may be different.

Prior to our 2015 Annual Meeting, on which date the annual cash retainer was increased to $40,000, the annual cash retainer for serving on the Board of Directors was $33,000, paid quarterly. Prior to July 17, 2015, on which date the initial RSU grant and annual refresh RSU grant for serving on the Board of Directors were changed to the above, non-employee directors received an initial grant of 20,000 RSUs vesting over a 4-year period and an annual refresh grant of 6,000 RSUs vesting over a 4-year period for serving on the Board of Directors. Otherwise, the compensation described above remained unchanged from the date of the 2015 Annual Meeting.

    Termination or Change of Control Arrangements

We have entered into change of control agreements with each of the non-employee directors. These agreements provide that upon a Change of Control, 100% of the unvested equity awards held by such directors will immediately vest.

“Change of Control” in our change of control agreements with our non-employee directors has the same meaning as used in our Change of Control Severance Agreements with the named executive officers. See “— Potential Payments Upon Termination or Change of Control — Termination or Change of Control Arrangements.”

    Other Arrangements

While non-employee directors are not typically paid or reimbursed for travel, lodging and related expenses associated with attending meetings of the Board of Directors or committees of the Board of Directors and for participating in activities related to service on the Board of Directors, we have from time-to-time paid or reimbursed our non-employee directors for reasonable expenses associated with attendance at meetings of the Board of Directors or committees of the Board of Directors.

Equity Compensation Plan Information

We currently maintain the following two equity compensation plans that provide for the issuance of shares of common stock to our officers and other employees, directors and consultants: the 2009 Equity Incentive Plan, as amended (the “2009 Plan”), and the 2011 Employee Stock Purchase Plan, each of which has been approved by stockholders, and the Meru Networks, Inc. 2010 Equity Incentive Plan (the “Meru 2010 Plan”), which has not been approved by stockholders. The Meru 2010 Plan was assumed by Fortinet on July 8, 2015 pursuant to an Agreement and Plan of Merger by and among Fortinet, Meru Network, Inc. and Malbrouck Acquisition Corp., dated as of May 27, 2015. We previously maintained the Amended and Restated 2000 Stock Plan (the “2000 Plan”) and 2008 Stock Plan (the “2008 Plan”), both of which we terminated in connection with our initial public offering in 2009. The termination of the 2000 Plan and 2008 Plan did not affect awards outstanding under the plans, which continue to be governed by the terms and conditions of the respective plans.

The following table summarizes the number of outstanding options and rights and number of securities remaining available for future issuance under our equity compensation plans as of December 31, 2015.
